Objective To explore the impact of HR-HPV infection on pregnancy outcomes and vaginal microbiota. Methods 128 pregnant women who underwent prenatal examinations at Mingshan Branch of the First Affiliated Hospital of Chengdu Medical College were selected as the research subjects. Both vaginal microbiota and HR-HPV testing were conducted, and single factor analysis and multiple linear regression analysis were used to identify the relevant factors of HR-HPV infection in pregnant women. The impact of HR-HPV infection on pregnancy outcomes and vaginal microbiota was studied. Results Among the 49 cases in the infection group, 30 cases contracted with type 16 HPV, accounting for 61.22%, 13 type 18 HPV, accounting for 26.53%, and 1 type 31, 33, 51, 52, 53, and 58, respectively. Univariate analysis showed that HR-HPV infections were significantly correlated with age of first sexual activity, condom use, number of sexual partners, reproductive tract inflammation, and smoking history (P < 0.05). Multivariate analysis showed that age of first sexual activity ≤ 20 years, concurrent reproductive tract inflammation, multiple sexual partners, and smoking history were independent risk factors for HR-HPV infection, while condom use was an independent protective factor for HR-HPV infection. There were significant differences in the number of lactobacilli, candida infections, and vaginal cleanliness between the two groups (P < 0.05). The incidence of spontaneous abortion and fetal growth restriction in the HR-HPV-infected group was significantly higher than that in the HR-HPV-uninfected group (P < 0.05). Conclusions Pregnant women with HR-HPV infections are closely related to factors such as premature sexual conduct, number of sexual partners, reproductive tract inflammation, and smoking. Infections with HR-HPV during pregnancy can cause changes in the vaginal microenvironment and lead to adverse pregnancy outcomes. [ABSTRACT FROM AUTHOR]

Objective: To analyze the characteristics of GBS infections in pregnant women in late pregnancy, associated factors, and their impact on reproductive tract microbiology, pregnancy outcomes. Methods: From June 2022 to June 2023, 982 late-pregnant pregnant women admitted to Yubei People's Hospital in Chongqing who received vaginal secretion examination, according to GBS infection, were divided into infected (98 cases) and uninfected (884 cases) groups. Factors influencing GBS infection in pregnant women in late pregnancy analyzed using univariate and Logistic regression, and the detection of genital tract microorganisms and pregnancy outcomes between the infected and uninfected groups were compared. Results: Age, body mass index (BMI), presence of preconception examination, presence of combined gestational hypertension, presence of combined gestational diabetes mellitus, and presence of vaginal and cervical inflammation were statistically different between the infected group and the uninfected group (P<0.05). Age ≥35 years, BMI ≥28 kg/m², combined gestational hypertension, combined gestational diabetes mellitus, and the presence of vaginal and cervical inflammation were the independent risk factors (OR=2.477, 3.077, 4.586, 3.540, and 2.942, P<0.05); and that pre-pregnancy checkups were the protective factor (OR=0.465, P<0.05). The detection rates of trichomonas, fungi, vaginosis and the incidence of premature rupture of membranes, intrauterine distress, neonatal pneumonia, and neonatal jaundice were higher in the infected group when compared to the uninfected group (P<0.05). Conclusion: GBS infection in pregnant women in late pregnancy were associated with age ≥35 years, BMI ≥28 kg/m², comorbid gestational hypertension, comorbid gestational diabetes mellitus, presence of vaginal and cervical inflammation, and pre-pregnancy checkups, and GBS infection could affect the microenvironment of the reproductive tract and cause the development of adverse pregnancy outcomes.

Performance artist Deborah de Robertis performed at the Musée d'Orsay in Paris on May 29, 2014, she showed her sexual organs to the public in front of Gustave Courbet's work 'The Origin of the World', and was immediately stopped, and persuaded to leave by the exhibition's female staff. This performance art caused an uproar, but also pointed out the central question of the aesthetic value of contemporary art: censorship. At 2011, Frédéric Durand-Baïssas, a French teacher, was suspended by Facebook for posting a picture of The Origin of the World on Facebook. Such cases of "challenging social norms in the name of art" are not uncommon in the field of contemporary art. These kinds of contemporary art creations, with their tendency to challenge norms, point to the core of contemporary art. Nathalie Heinich, sociologist of art, has analyzed this "tolerant contradiction" of contemporary art. [ABSTRACT FROM AUTHOR]

In order to investigate the effects of different combinations of plant growth regulators on the growth and development of cotton, Zhongmiansuo 117 was used as the test variety, and mepiquat was used to combine with low, medium, and high concentrations of diethyl aminoethyl hexanoate, 24- epibrassinolide and prohexadione calcium in a randomized block group trial, and three sprays were carried out from the early to the full bloom stage of cotton to analyze the effects of the spraying on cotton agronomic traits, dry matter accumulation, yield, and quality and other indexes. The results showed that: mepiquat 98% SP 45 g/hm² + diethyl aminoethyl hexanoate 5% SL 120 mL/hm² and mepiquat 98% SP 45 g/hm² + prohexadione calcium 10% SC 450 mL/hm² showed a good effect on stemming control, increased the number of fruiting shoots and the diameter of the main stems, and promoted the bolling of cotton plants. The combination of mepiquat 98% SP 45 g/hm² + diethyl aminoethyl hexanoate 5% SL 120 mL/hm² significantly increased the seed cotton yield, the number of bolls per hectare and the weight of single bolls, and also improved the degree of neatness to a certain extent; the endogenous GA3 increased, and the IAA and ABA decreased, which helped to increase the quality of the yield in the actual production. The combination of mepiquat 98% SP 45 g/hm² + prohexadione calcium 10% SC 450 mL/hm² significantly increased the amount of aboveground dry matter accumulation and dry matter distribution ratio of reproductive organs. It also regulated the increase of endogenous ABA and effectively promoted nutrient transfer to reproductive organs. The study showed that the combination of mepiquat 98% SP 45 g/hm² + diethyl aminoethyl hexanoate 5% SL 120 mL/hm² and mepiquat 98% SP 45 g/hm² + prohexadione calcium 10% SC 450 mL/hm² could realize the trait control and yield increase through the endogenous hormone regulation, which is of practical application in production.

Objective Soil nitrogen and groundwater table are two abiotic factors affecting crop growth in the middle and low reaches of the Yangtze River in Southern China. This paper aims to investigate the combined impact of nitrogen fertilization and controlled drainage on growth, nitrogen uptake and yield of cotton. Method The variety Jinghua Mian 112 was used as the model plant, and the experiment consisted of two drainage treatments: conventional drainage (FKS) and controlled drainage (KS). Each irrigation had five nitrogen treatments: applying 0 (N0), 90 (N1), 180 (N2), 270 (N3) and 360 kg/hm2 (N4) of nitrogen. In each treatment, we measured the leaf SPAD at fertility stage, plant height and leaves at blooming stage, dry matter accumulation in different organs at maturity stage, as well as nitrogen uptake, and yield of the cotton. Result Compared with FKS, controlled drainage combined with a reduction in nitrogen application significantly increased leaf SPAD and plant height at flowering stage, dry matter accumulation and nitrogen uptake at maturity stage, boll numbers per plant, boll weight per boll and yield at maturity stage. Reducing nitrogen application without implementing controlled drainage reduced cotton yield, while under controlled drainage, reducing nitrogen application from N4 to N3 did not give rise to a noticeable reduction in cotton yield. KS+N3 increased the dry matter mass, nitrogen uptake per unit dry matter, and total nitrogen uptake in the bud and boll, significantly. Conclusion Reducing nitrogen application currently used by farmers by 25% combined with a controlled drainage is not only beneficial to cotton growth and promotes dry matter accumulation, but also increases nitrogen uptake and its subsequent allocation to reproductive organs, thereby increasing cotton yield.

There are many kinds of reproductive tract flora, which are symbiotic and antagonistic to each other. They play an important role in defending infection, promoting pregnancy and maintaining a normal intrauterine environment. The metabolites produced by the interaction between the reproductive tract flora and the host are not only related to flora imbalance and host immunity, but also related to adverse pregnancy outcomes. In recent years, the research on the correlation between the role of reproductive tract flora in pregnancy has gradually attracted the attention of the academic community. Therefore, this article attempts to explain the complex interaction between the reproductive tract flora and the host from the aspects of the role of vaginal and cervical flora, uterine cavity flora, fallopian tube and follicular fluid flora in normal pregnancy, as well as the correlation between common microorganisms in the reproductive tract and adverse pregnancy outcomes, in order to provide a basis for studying the mechanism and treatment of adverse pregnancy outcomes.

Through analyzing the views of various experts and collecting the records of testis in ancient and modern literature, this paper summarizes and discusses the visceral manifestation of the testis. The testis is included in the seminal chamber (male cell) and can be attributed to the extraordinary fu-organ. It has the characteristic of “ like zang-organ like fu-organ and capable of storing and excreting” . The essence stored in the testis plays a key role in male fertility and female pregnancy, so the testis is also one of the effective organs that reflects the function of the kidney in governing reproduction. Shaped like a ball, the testis is located in the male’ s external genitalia, and in ancient times it had names including “egg”, “pill”, “yin pill”, and “drop”. Its physiological characteristics are delicate testis, preference for cool and aversion to heat, easy to be susceptible to external forces, temperature, humidity, mood and other factors. Moreover, the testis is yin in property and yang in function, which manifests as follows: the anatomical testis filling with yin essence refers to yin in property, while the testicular functions based on kidney qi refer to yang in function. Based on physiological characteristics, the testis is crucial for the production, storage, and excretion of reproductive essence. It promotes the development of male reproductive organs and thereby ensures male fertility and female pregnancy. [ABSTRACT FROM AUTHOR]

Objective: To analyze the influencing factors of incision infection after cesarean section in patients with gestational diabetes mellitus (GDM) and to explore the predictive value of serum procalcitonin (PCT) and glycosylated hemoglobin (HbA1c) on the infection risk. Methods: 253 patients with GDM who underwent cesarean section in our hospital from January 2020 to January 2022 were selected, and they were divided into infection group and non-infection group according to whether incision infection occurred after cesarean section. Serum PCT and HbA1c levels were detected. Univariate and multivariate Logistic regression were used to analyze the influencing factors of incision infection after cesarean section in patients with GDM. Receiver operating characteristic (ROC) curve was used to analyze the predictive value of serum PCT and HbA1c on incision infection after cesarean section in patients with GDM. Results: The incidence of incision infection after cesarean section in 253 patients with GDM was 15.02% (38/253). Univariate analysis showed that age greater than or equal to 35 years, operation time≥ 1 h, intraoperative blood loss greater than or equal to 500 mL, anal examination/vaginal examination≥ 3 times, amniotic fluid contamination, premature rupture of membranes, genital tract inflammation ratio, PCT and HbA1c in the infection group were higher than in the non-infection group, and the proportion of prophylactic use of antibiotics was lower than that in the non-infection group (all p<0.05). Multivariate Logistic regression analysis showed that operation time≥ 1 h, anal examination/vaginal examination≥ 3 times, amniotic fluid contamination, premature rupture of membranes, genital tract inflammation, increased PCT, and increased HbA1c were independent risk factors for incision infection after cesarean section in patients with GDM (P<0.05). Prophylactic use of antibiotics was an independent protective factor (P<0.05). ROC curve analysis showed that the area under curve of serum PCT and HbA1c in predicting incision infection after cesarean section in patients with GDM were 0.797, 0.774 and 0.875, respectively. Conclusion: Operation time, prophylactic use of antibiotics, anal examination/vaginal examination, ammiotic fluid contamination, premature rupture of membranes, genital tract inflammation, PCT and HbA1c are the influencing factors of incision infection after cesarean section in patients with GDM. The combined preoperative serum PCT and HbA1c has a high value in predicting incision infection after cesarean section. [ABSTRACT FROM AUTHOR]

BACKGROUND: Cardiomyocyte apoptosis plays a critical role in ischemia/reperfusion injury. Recent studies have shown that PIWI-Interacting RNA (piRNA), a reproductive system regulator, participates in the pathogenesis of cardiac disorder. However, the role of piRNA in cardiomyocyte apoptosis has not been clarified; especially the mitochondria-dependent pathway involved is poorly understood. OBJECTIVE: To study the role and molecular mechanism of piRNA-5938 in cardiomyocyte apoptosis and mitochondrial fission. METHODS: The abundance of piRNA in normal and ischemic/reperfusion hearts of mice and rats was detected by deep sequencing, and the results were verified by real-time fluorescence quantitative PCR. Cardiac apoptosis was induced by hydrogen peroxide or anoxia/reoxygenation, in which the expression level of piRNA-5938 was detected by real-time fluorescence quantitative PCR. piRNA-5938 antagomir was synthesized and transfected into cardiomyocytes and then the cells were treated with hydrogen peroxide. Apoptosis was detected by TUNEL and mitochondrial division was evaluated by MitoTracker. RNAhybrid software was used to predict microRNAs that interact with piRNA-5938. RESULTS AND CONCLUSION: Compared with the sham group, the expression levels of 422 piRNAs were changed in the mouse ischemic/reperfusion heart, of which 289 were up-regulated and 133 were down-regulated, and piRNA-5938 expression increased significantly (P < 0.01). The expression level of piRNA-5938 was significantly up-regulated after cardiomyocyte apoptosis induced by H2O2 in a concentration-dependent manner (P < 0.05). piRNA-5938 was significantly increased after anoxia/reoxygenation-induced cardiomyocyte apoptosis (P < 0.01). Compared with the negative control group, knockdown of piRNA-5938 significantly reduced the apoptosis rate of cardiomyocytes induced by hydrogen peroxide (P < 0.05). The mitochondrial fission induced by hydrogen peroxide was significantly inhibited by the knockdown of piRNA-5938 (P < 0.05). piRNA-5938 was highly conserved in complementation with mitochondrial fission regulators mir-324 and Mir-668. To conclude, piRNA-5938 regulates cardiomyocyte apoptosis and mitochondrial fission, which probably functions through targeting mir-324 or mir-668. [ABSTRACT FROM AUTHOR]

Immunosuppressants are widely used in the treatment of rheumatic immune diseases, but most of them have toxic side effects, causing damage to the immune, digestive, reproductive and other systems, not only reducing patient compliance, but also seriously affecting disease prognosis. At present, Western medicine has no clear solution for the toxic side effects of immunosuppressants. The theory of traditional Chinese medicine(TCM) states that immunosuppressants such as glucocorticoids and cytotoxic drugs are mainly aggressive products. Long-term use of immunosuppressants can damage the lung, spleen and kidney, damage the vital qi of the body, and lead to deficiency symptoms occur. “ Treating deficiency with three sources and two systems” is the great method developed by Wang Qishi, a doctor in the late Ming Dynasty, to treat deficiency and fatigue. After continuous enrichment and development in later generations, this has become a classic theory for treating consumption diseases. We studied the toxic side effects of immunosuppressants from the perspective of “treating deficiency with three sources and two systems”. We believe that the symptom of consumption caused by immunosuppressants should be treated from the “ three sources” of lung, spleen and kidney, and the two types of syndromes of kidney yin deficiency and kidney yang deficiency should be treated from the “two systems” of lung and spleen. In clinical practice, we can determine the corresponding treatment principles according to different system’s injury syndromes, so as to provide a TCM scheme for safe clinical drug use and expand the theoretical system of toxicity reduction based on TCM.

Persistent genital arousal disorder (PGAD) and genito-pelvic dysesthesia (GPD) jointly known as persistent genital arousal disorder/genito-pelvic dysesthesia syndrome (PGAD/GPD) , which was a unique disorder characterized by spontaneous or secondary genital arousal and dysesthesia in the genital and pelvic areas discovered abroad in recent years. In addition, no relevant reports on PGAD/GPD have been found in CNKI, WanFang Data, and VIP. Discovery of posture secret (DPS) is a manual therapy technique with the 4R principle as the core developed from the integration of various mainstream posture correction techniques in the world, which has unique curative effect on improving musculoskeletal pain and abnormal posture. This article reports a domestic case of complete remission of symptoms of PGAD/GPD treated with DPS, and reviews relevant foreign literature on PGAD/GPD, in order to raise the attention of domestic peers.

[Objectives] To identify morphological criteria for sexing Trigonorhinus sp., an important wood-boring pest of Caragana liouana Zhao Y. Chang & Yakovlev. [Methods] The following morphological characteristics of adult Trigonorhinus sp. were measured; body length, body width and length of the 6th abdominal plate, as well as whether the wing sheath completely covered the end of the abdomen. [Results] 1) The end of the abdomen of females is concave and bifid in the center, whereas that of males is bluntly rounded. 2) The 6th abdominal plate of females is significantly longer (0.48± 0.01) mm than the 5th plate of males which was significantly shorter [(0.30±0.01) mm]. The proportion of body length comprised by the 6th abdominal plate [(0.16±0.01) mm] is greater in females than in males [(0.11±0.02) mm]. 3) Wing sheaths completely cover the end of abdomen in females, but not in males. [Conclusion] Although is difficult to sex adult Trigonorhinus sp. on the basis of body size alone, they can be readily sexed by the length of the 6th belly plate. However, definitive sexing requires examination of the external genitalia. [ABSTRACT FROM AUTHOR]

Background and purpose: Peutz-Jeghers syndrome (PJS)-related diseases in female reproductive system include lobular endocervical glandular hyperplasia (LEGH), gastric type adenocarcinoma of the uterine cervix (GAS) and sex cord tumor with annular tubules (SCTAT), etc. In particularly, PJS-related LEGH has an early age-onset, and the disease could progress rapidly to GAS. Early diagnosis is difficult, and the prognosis has been proved poor, which brings great challenges to the diagnosis and treatment of patients. Research data are limited, especially in China. The purpose of this study was to investigate the clinical manifestations, disease pattern, related risk factors, and the status of disease screening, management of gynecological diseases in Chinese PJS patients, providing more clinical evidence and helping with the early screening and early diagnosis of gynecological diseases, especially malignant diseases in female PJS patients. Methods: Based on the status of management of gynecological diseases in female patients with PJS and patients’ feedback, our questionnaire was designed and launched from March 26th, 2022 to July 29th, 2022. The general condition, past family history, past medical history, gynecological clinical manifestations and management of the patients were investigated. A stratified analysis of each item was conducted to find out the high-risk factors and protective factors associated. Results: A total of 154 valid questionnaires were recruited in our study, and 5 patients were excluded according to the inclusion/exclusion criteria. 114/149 patients (76.51%) had gynecological symptoms, and the main complaint was abnormal uterine bleeding (83 patients, 55.70%), nearly half of them had vaginal watery discharge (62 patients, 41.61%), 47.65% (71/149) had received cervical screening tests, and the human papilloma virus (HPV) positive rate was only 7.04%. Only one-third of the patients (55/149, 36.91%) had received genetic testing, and 52 patients had STK11 mutations (94.5%). 64.52% were truncating mutations, but with no significant differences in the incidence and oneset age of gynecological disease compared with non-truncating mutations in our cohort. STK11 germline mutations were found all over the whole gene, while no mutation found in non-coding exon 9. Exon7 was found with the highest mutation rate (25.81%). Unrelated patients with the same STK11 mutation had completely different disease spectrum and onset age of gynecological diseases. Among the patients with gynecological cancer treated with surgery, 1/3 were found with synchronous mucinous metaplasia and neoplasia of the female genital tract (SMMN-FGT) on pathology. Less than half received standardized intervention and prompt surgery, and only 73.33% of them received adjuvant therapy. Only 40% of the patients completed fertility before surgery, and none received PGT. Conclusion: This study first put the focus on the gynecological symptoms, diagnosis and management of Chinese women with PJS. We found that abnormal uterine bleeding and vaginal watery discharge were the main symptoms in half of the women with PJS, and the age of onset was significantly shifted to the younger population. Truncating mutations, as the main mutation type in Chinese women with PJS, has no significant association with clinical phenotype, for which the mutation type does not affect their risk of cancer or age onset. Environmental factors may play an important role in disease development and progression of PJS patients as the age onset and disease spectrum of unrelated females carrying the same STK11 mutation were completely different. At the same time, the awareness of genetic counseling and gynecological disease screening system have not been established in the PJS female population, as the genetic test coverage is low (1/3), and only less than half of the patients with gynecological cancer received standard surgery and adjuvant therapy. PJS patients with gynecological cancer generally have low fertility rate, and only one case received PGT in our cohort, which is mainly due to the low cognition and understanding of PJS in our society. The low coverage of genetic counseling, and the delay of intervention made PJS patients, especially females with gynecological diseases lose their fertility opportunity. [ABSTRACT FROM AUTHOR]

BACKGROUND: It has been recently discovered that vitamin D receptor is widely distributed in the female reproductive system such as the ovary and uterus, which is closely related to adverse pregnancy outcomes such as spontaneous abortion and gestational diabetes mellitus, but its specific mechanism is still unclear. OBJECTIVE: To investigate potential differentially expressed miRNAs and related regulatory networks via a whole transcriptome analysis of the uterine tissue of vitamin D-deficient mice. METHODS: Eighteen female C57BL/6J mice were randomly divided into two groups: a vitamin D deficiency group and a normal control group. Mice in the vitamin D deficiency group were fed with vitamin D deficiency diet, and mice in the normal control group were fed with vitamin D sufficiency diet. The body mass of the mice was recorded every week. After 8 weeks, the serum levels of 25,(OH)D3 and hormones in the mice were tested. Hematoxylin-eosin staining was used to detect mouse uterine tissue. Uterine tissue samples of two groups were collected for transcriptome sequencing, and bioinformatics analyses of gene ontology and Kyoto encyclopedia of genes and genomes. RESULTS AND CONCLUSION: There was no difference in body mass between the two groups. Compared with the normal control group, the levels of 25,(OH)D3 and estradiol in mouse serum were significantly reduced, and the testosterone level was significantly increased in the vitamin D deficiency group. Hematoxylin-eosin staining of uterine tissue showed a reduction in the endometrial folds of mice in the vitamin D deficiency group. Twenty-five differentially expressed miRNAs were screened out by transcriptome sequencing, of which 9 were up-regulated (such as miR-541-5p and miR-205-5p) and 16 were down-regulated (such as miR-378d and miR-708-5p). At the same time, vitamin D deficient mice showed significantly differences in multiple gene ontology enrichment categories, such as developmental process, cell composition, tissue or biogenesis. In addition, the functional enrichment results of Kyoto genes and genomes encyclopedia showed that differentially expressed genes were mostly related to biochemical metabolic pathways and signal transduction pathways. Differentially expressed genes in these enrichment pathways mainly affected PI3K-Akt signaling pathway, MAPK signaling pathway, insulin signaling pathway, gonadotropin releasing hormone signaling pathway, and oocyte meiosis pathway, all of which were closely related to the regulation of the reproductive system. To conclude, vitamin D deficiency can lead to poor uterine implantation conditions in female mice, which is related to multiple signaling pathways, such as insulin regulation, in mouse reproductive system.

Objective To evaluate the effects of underground coal mine work on semen quality, sperm function, and the outcome and their offsprings of assisted reproductive technology. Material and methods Clinical data of 56 male infertility coal miners with genital tract ureaplasma urealyticum positive who underwent assisted reproductive treatments from January 2016 to December 2020 (the experiment group) were retrospectively analyzed. Other 103 men with normal and natural history of fertility was set as the control group. Semen quality, sperm function, and the outcome and their offsprings of assisted reproductive technology were comparatively analyzed between the experiment group and the control group. Result There were no significant differences between the experimental group and the control group in the average age and years of infertility, the number of the antral follicle, E2 level on HCG day, basic FSH, basic LH, intimal thickness on HCG day in male and female patients. There were no significant differences between the two groups in semen volume, sperm concentration, but there was a significant difference in percentages of progressively motile sperm, sperm motilityand morphologically normal sperm. There were no significant differences in acrosin activity and sperm hyaluronic acid binding rate between the two groups. The sperm DNA fragmentation and sperm nucleoprotein transition in the experiment group were higher than those in the control group, and the difference were statistically significant. The fertility rate and optimal embryos rate in the control group were higher than those in the experiment group. There were no significant differences in the cleavage rate, implantation rate,biochemical pregnancy rate, and clinical pregnancy rate of embryo rate between two groups. There were no significant differences in abortion rate,the pregnancy rate of heavy twins, the proportion of male babies and the rate of birth defects between the two groups. Conclusion Long term coal mine work may have adverse effects on semen quality, sperm function and the outcome of assisted reproductive pregnancy, but little effects on their offsprings of assisted reproductive pregnancy.

Insufficient or excessive intake of trace copper by livestock and poultry bodies has a negative impact on their reproductive systems, restricting the development of breeding pigs, eggs, dairy and other industries. Copper, as an essential trace element for animal bodies, has functions such as bactericidal and anti-oxidation, which is often used as a feed additive in pharmacological doses in animal production. Reproductive health is very important to animal production. The article reviews the effects of trace copper elements on animal reproductive performance and the copper content in feeds, to provide reference for the rational use of copper in animal production.

BACKGROUND: As the core organ of female reproductive system, ovary exerts female reproductive function through ovulation and hormone secretion, and affects the tissues and organs of the whole body. With the acceleration of population aging and a variety of inducements, the number of people with ovarian aging is increasing, but ovarian aging is still in the preliminary research stage, which is still a scientific problem to be solved. OBJECTIVE: To investigate the effect of bone marrow mesenchymal stem cells on the repair of ovary of aging macaques. METHODS: Ten healthy old female monkeys, aged 23-27 years old and weighing 4.5-8.0 kg, were randomly divided into elderly control group (n=4) and elderly treatment group (n=6). The P4 bone marrow mesenchymal stem cells of young macaques were intravenously infused into elderly macaques, once a day, every other day, for three consecutive times. The elderly control group was infused with equal volume of normal saline at the same time. At the 8th month after the infusion of bone marrow mesenchyme stem cells, macaques were euthanized to take ovarian tissues, weighed, and fixed with 40 g/L paraformaldehyde. Hematoxylin-eosin staining was used to observe the structural changes of various levels of follicles for ovary. TUNEL staining was used to calculate the apoptosis rate. Masson staining was applied to analyze the area ratio of collagen. Immunohistochemistry was employed to observe the number of CD34-labeled positive blood vessel. RESULTS AND CONCLUSION: (1) The ovarian organ index of the elderly control group was 1.8×10-5, and the ovarian organ index of the elderly treatment group was 6.0×10-5. There was significant difference between the two groups (P < 0.05). (2) Hematoxylin-eosin staining results showed that original, primary, secondary and atresic follicles were seen in the elderly treatment group, but mature follicle was not found; the medulla and stroma were obvious, and there were a few calcium nodules; the elderly control group basically had no follicular structure, only atresic follicle was seen in the local area, which was filled with a lot of fatty tissue. (3) Masson staining results showed that the area ratio of collagen fibers was significantly lower in the elderly treatment group than that in the elderly control group, and significant difference was found between the two groups (P < 0.05). (4) TUNEL staining results showed that the apoptosis rate was lower in the elderly treatment group than that in the elderly control group, and significant difference was found between the two groups (P < 0.05). (5) The results of immunohistochemistry showed that the number of blood vessels in the elderly treatment group was more than that in the elderly control group, and significant difference was found between the two groups (P < 0.05). (6) Results suggest that bone marrow mesenchymal stem cells can promote follicle regeneration, improve ovarian tissue structure, reduce ovarian cell apoptosis, inhibit the progression of ovarian fibrosis, and promote blood vessel regeneration, to delay even reverse ovarian senescence.

Habitats influent the divergence of floral traits. To test whether habitats change could affect the floral traits and resources allocation of Rhododendron plants and investigate the distribution of Rhododendron plants in different colors. R. delavayi, R. agastum and R. irroratum in high, medium and low intensity human interference habitats were taken as materials. Five-point sampling method was used to count the number of Rhododendron plants in different habitats, floral traits were measured by a vernier caliper, the number of pollen grains were counted by a light microscope, the spectral reflectance of colors was measured by an ocean spectrometer, and the Gephi software was used to draw network diagrams of the number of plants. The results were as follows:(1)The plant number of R. agastum was significantly higher than that of R. delavayi and R. irroratum.(2)The trait indexes of vegetative and reproductive organs of R. delavayi in low intensity interference habitat were higher than those in high and medium intensity interference habitats; Different intensity interference habitats had no significant influence on floral traits of R. agastum; The trait indexes of vegetative and reproductive organs of R. irroratum in medium and low intensity interference habitats were significantly higher than those in high intensity interference habitats.(3)The colors of R. delavayi and R. agastum showed higher reflection values at 400-500 nm wavelengths, while colors of R. irroratum showed higher reflection values at 400-700 nm wavelengths.(4)R. agastum was distributed closely with the other two species of Rhododendron in high and medium intensity interference habitats, while R. delavayi and R. agastum were more closely distributed in low intensity interference habitat. This study provides a crucial theoretical basis for the population management and biodiversity conservation of Rhododendron species. [ABSTRACT FROM AUTHOR]

BACKGROUND: There is no objective and systematic analysis of data reported in the literature regarding pelvic reduction techniques, which is not conducive to the rapid and intuitive understanding of relevant research trends. OBJECTIVE: To search Chinese and English databases for all research data on pelvic reduction techniques, and to analyze the current regional characteristics, research status and development trends of pelvic reduction techniques. METHODS: A search of CNKI and Web of Science was performed for all relevant literatures on pelvic reduction published from inception to March 26, 2020. CiteSpace software was used to perform a document visual analysis in terms of publication year, country, journal content as well as author cooperation, document types, and key words. RESULTS AND CONCLUSION: In total, 149 articles were included, and the number of publications was generally on the rise. The number of publications was the most in the United Stated, with the highest citations, whereas China ranked 5th, with mutual references with the United Kingdom, Canada, and Australia ranking at the top. The research hotspots in this field mainly include the application of pelvic reduction techniques to deal with diseases of orthopedics and traumatology, and American chiropractic treatments for pelvic reduction that affect the reproductive and urinary systems in men and women. The clinical application of pelvic reduction techniques was relatively simple in the early stage, and mostly limited to related diseases of orthopedics and traumatology. With the development and maturity of medical technology, related reduction techniques have developed to focus on orthopedics and traumatology, rehabilitation, as well as rehabilitative therapies for diseases in gynecology, obstetrics, urology, and sports. With the continuous deepening of research on pelvic reconstruction techniques, increasingly closed exchanges between China and foreign countries and more complete data sharing platform, related applications and research prospects look promising. Existing pelvic reduction techniques focus on the displacement of bony joints, whereas further exploration on the longterm efficacy is warranted. Pelvic reduction makes some changes in tissue structure displacement, which influences vascular hemodynamics, nerve conduction, biochemical factors and signal pathways. This may be the future direction of in-depth research. [ABSTRACT FROM AUTHOR]

[ Objective] The purpose of this study was to investigate the effects of light duration on the morphology and structure of ovary and fallopian tube and the main reproductive hormones of Guizhouhuang chickens. [ Method] The serum levels of follicle stimulating hormone ( FSH), luteinizing hormone ( LH) and estradiol ( E2) in Guizhouhuang chickens were measured at 140, 200 and 480 days of age, respec tively, under the condition of Half-housed breeding ( house feeding + sports field) and with natural light as the control, and the develop ment of main reproductive organs and the histological characteristics of reproductive organs were observed. [Result] At 140 days of age, ovi duct weight under increased light treatment was significantly lower than that under natural light treatment, and the maximum follicle diameter under light treatment was significantly higher than that under natural light treatment. There were no significant differences in ovary weight, o viduct length, the number of large yellow follicles and the number of small yellow follicles between the two treatments. At 200 days of age, there was no significant difference in ovarian weight and maximum follicle diameter between the two treatments. All the other indexes were significantly higher under increased light than those under natural light. At 480 days of age, the tubal weight of increased light treatment was significantly lower than that of natural light treatment, but there were no significant differences among other indexes. Increasing light had no significant effect on the ovarian tissue structure. The contents of FSH and E2 under increased light treatment were significantly higher than those under natural light treatment at 140 and 200 days of age. FSH, LH and E2 at 480 days of age had no significant differences among treatments. [Conclusion] Appropriate increase of light can improve the production performance of Guizhouhuang chicken.

The objective of this study is to explore the effects of degradation properties of different biodegradable films on water environment and yield formation of cotton（Gossypium hirsutum L.）field under drip irrigation conditions. A single factor field experiment was established, completely randomized block design：Four kinds of biodegradable films Tianzhuang-1（T1）, Tianzhuang-2（T2）, Jinfa （JF）, Basf（BSF）, and polyethylene agricultural film（PE, CK）were applied. The experiment was carried out in southern Xinjiang in 2018. During the experiment, the degradation rate of biodegradable films, soil water content, dry matter accumulation and seed yield were measured. Water use efficiency（WUE）was calculated based on the evapotranspiration. The results showed that, the degradation rate of the films decreased, in the order of T2>T1>JF>BSF. Only T2 entered into the full degradation phase at the end of the growth period, while the other mulching films were still in the fragmentation stage. Soil moisture content of BSF treatment was 17.9% and 18.5% respectively, higher than that of the polyethylene film in bud stage and flowering stage, and remained relatively stable. For T2 treatment, very early degradation occurred, soil moisture rapidly evaporated, deep water consumption increased, and dry matter accumulation decreased. For JF treatment, it was the last one to enter into the rapid dry matter accumulation（78 d after covering film）. The number of bolls per plant was 1.69 less, and single boll weight was 0.14 g lower than that of polyethylene film, resulting in 40.82% reduction in yield. For T1 treatment, there was no significant decrease on soil moisture content, and reproductive organ ratio during boll opening stage, seed cotton yield, and WUE in the cotton field were observed and compared with that of polyethylene film. T1 mulching film could reduce the pollution caused by residual film, while ensuring stable yield under the local environment. [ABSTRACT FROM AUTHOR]

Hopea chinensis is one of the representative tree species of tropical seasonal rainforests in China. It is an endangered and protected plant with beautiful tree shape and cold tolerance. To clarify its pollination biology, and breeding system and demonstrate its reproductive potential in Guilin, where this species was introduced for protection, we conducted the following experiments: the observation of flowering phenology, the measurement of floral size and scent, the estimation of the breeding system by out-crossing index(OCI), the pollen-ovule ratio(P/O), pollen viability and the stigma receptivity and self-pollination, the observation of pollinators and the test of their pollination effectiveness, the assessment of reproductive potential and pollination limitation by hand cross-pollination. The results were as follows:(1)The flowering season of H. chinensis in Guilin Botanical Garden is from the end of July to the end of September. It lasts about 60 d. An inflorescence flowers for about 12 d, and the anthesis of a single flower lasts about 3 d. The flowers begin opening from 17:00 to 18:45.(2)H. chinensis is not dichogamous but herkogamous with stigmas higher than anthers. The period of high pollen vigor and that of high stigma receptivity largely coincide.(3)The outcrossing index(OCI)was four and pollen/ovule ratio(P/O)was 10 788±984.(4)Neither flowers self-pollinated nor thoses bagged all the tome set any fruitse, fruit set did not differ significantly between natural pollination and hand cross-pollination.(5)Fungus gnats were the only flower visitor to the H. chinensis in Guilin Botanical Garden and flowers set no fruits with fungus gnat excluded.(6)The floral scent is dominated by β-elemene,(E)-7,11-dimethyl-3-methylene-1,6,10-dodecatriene and 1-caryophyllene. In conclusion, H. chinensis breeding system is self-incompatible, and it relies on fungus gnats for fruit production. It can set fruits and produce mature seeds in Guilin. The results can promote the protection and propagation of H. chinensis. [ABSTRACT FROM AUTHOR]

To explore the correlation between female genital tract Ureaplasma urealyticum (Ureaplasma urealyticum, UU) infection and premature rupture of membranes and neonatal asphyxia. From June 2017 to June 2019, 108 cases of pregnant women who were selected as outpatients in the region were selected, all the cases were to detect the genital tract Ureaplasma urealyticum infection. The general information, delivery methods, premature rupture of membranes, and neonatal asphyxia were investigated for all pregnant women and were given correlation analysis. There were 48 cases were detected Ureaplasma urealyticum infection in the 108 cases that the infection rates were 44.4 %. There were no significant difference in age, body mass index, parity, pregnancy time, years of education, and gestational age compared between the infected group and the non-infected group (P>0.05). The incidences of premature rupture of membranes and neonatal asphyxia in the infected group were 22.9 % and 18.8 %, respectively, which were significantly higher than that in the non-infected group of 3.3 % and 1.7 %(P<0.05). The cesarean section rates in the infected group were higher than that in the non-infected group, and the natural delivery rate were lower than that in the non-infected group that compared the differences were statistically significant(P<0.05). In the 108 pregnant women, Pearson analysis showed that Ureaplasma urealyticum infection were associated with premature rupture of membranes and neonatal asphyxia(P<0.05). Ureaplasma urealyticum infection in female genital tract is relatively common, which can lead to an increase in the incidence of cesarean section, premature rupture of membranes, and neonatal asphyxia. It is also significantly associated with premature rupture of membranes and neonatal asphyxia. [ABSTRACT FROM AUTHOR]
