In order to investigate the vertical distribution characteristics of soil organic carbon and its influence mechanism in Castanopsis orthacantha evergreen broad-leaved forest in Central Yunnan Plateau, we selected Castanopsis orthacantha forest at different altitudes(2 090-2 490 m) and different slope directions as objective to investigate the spatial distribution characteristics of organic carbon(SOC), microbial biomass carbon(MBC), soluble organic carbon(DOC), easily oxidized organic carbon(ROC), and granular organic carbon(POC) at 0-60 cm depths of soil. The results revealed:the contents of SOC, MBC, ROC, and POC initially increased and then decreased with increase of elevation, and the content of DOC decreased gradually with increase of elevation; the contents variation of the four active organic carbon fractions were followed as POC>ROC>MBC>DOC. The contents of soil organic carbon and active fractions were higher on the shady slope compared to the sunny slope, and decreased with soil depth significantly, the contents in 0-20 cm depth were higher obviously than that in 20-40 cm and 40-60 cm depth. The proportion of each soil active organic carbon component in soil organic carbon was POC/SOC>ROC/SOC>MBC/SOC>DOC/SOC, the particulate organic carbon(POC) was the main carbon pool among the four active carbon pools. The ratios of MBC/SOC have no significant variation with increase of elevation, while the ratios of ROC/SOC and POC/SOC finitially increased and then decreased. The contents of SOC, MBC, ROC and POC were positively correlated with each other, labile organic carbon was significantly negatively correlated with pH of soil. Altitude and soil depth have extremely significant impact on SOC, DOC, MBC, ROC and POC content. Slope direction highly significant effect on SOC, POC content and significantly affects DOC content.

The Tarim River is the largest inland river in our country. Its basin has formed a diverse natural ecosystem with water as the link from the upper reaches to the lower reaches. However, due to its location in an arid region, the ecological fragility within the basin has been a concern. With the increase in population and water consumption in the middle and upper reaches, the downstream ecological water use of the Tarim River was greatly squeezed, leading to year-round flow cessation, degradation of the ecological environment, and severe land desertification. Since 2000, our country has vigorously implemented ecological water diversion projects, providing artificial intermittent water supply to the downstream of the Tarim River for 20 consecutive years. This has significantly raised the groundwater level in the downstream area, greatly improving the vegetation and species diversity along the desert riverbanks, and making a huge contribution to the restoration and sustainability of the ecosystem in the downstream of the Tarim River. The article summarizes a large number of studies on the adaptive renewal and physiological responses of the Tamarix population in the lower reaches of the Tarim River since the implementation of the ecological water conveyance project. It focuses on the characteristics of Tamarix seedling growth adaptation and the reality of water and salt stress in the downstream area. It explores the relationship between the occurrence of Tamarix seedlings and ecological water overflow in the lower reaches of the Tarim River. It analyzes the reasons for the difficulty of natural renewal of Tamarix populations downstream. Based on this, it proposes a "strong-weak alternation" water conveyance model, aiming to more effectively utilize water overflow to achieve large-scale natural renewal of the Tamarix population in the lower reaches of the Tarim River, reduce the risk of population decline from the perspective of reproductive ecology, and enhance the stability of the desert riparian ecosystem.

Background Chronic insomnia is characterized by a prolonged and recurrent course. The efficacy of repeated transcranial magnetic stimulation (rTMS) as a physical therapy method to improve sleep quality remains inadequately supported by evidence, particularly regarding its relationship with personality traits. Objective To explore the efficacy and influencing factors of rTMS in the treatment of chronic insomnia, and to provide insights into its therapeutic potential. Method A total of 46 patients who met the diagnostic criteria for chronic insomnia according to the Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5), and were treated at the Third Hospital of Mianyang from September 2022 to September 2023 were selected. Prior to treatment, participants underwent assessments using the Eysenck Personality Questionnaire (EPQ), Hamilton Depression Scale-17 item (HAMD-17) and Hamilton Anxiety Scale (HAMA). The Pittsburgh Sleep Quality Index (PSQI) was used to assess sleep quality before treatment, at the end of the second week of treatment and one week post-treatment. Results At the end of the second week of treatment, patients exhibited significantly improved total PSQI score and subscale scores related to subjective sleep quality, sleep latency, sleep duration, sleep efficiency, sleep disturbance and daytime dysfunction (t=4. 755~13. 361,P<0. 01), with 24 cases (54. 35%) showing effective treatment outcomes. Multiple linear regression analysis showed that introverted and extroverted personality traits contributed significantly to the regression equation (B=0. 317,P<0. 01), explaining 29. 90% of the total variation (R² =0. 299). Conclusion rTMS treatment may effectively improve the sleep quality of patients with chronic insomnia, with its therapeutic effect appearing to associated with introverted and extroverted personality traits.

A self-designed questionnaire was used anonymously to investigate the knowledge and awareness level of human papilloma viruses（HPV）and vaccination behavior among interns from four hospitals in Jiangsu Province. This study aims to explore the influencing factors of vaccination behavior. A total of 1 250 questionnaires were distributed，and 1 230 valid copies were recalled. The results showed that the awareness rate of cervical cancer was 53.6%，while that of HPV was 33.3% and 54.7% of the students were aware of HPV vaccination. The knowledge of vaccine was obtained through school education（42.0%），official propaganda （36.1%），media communication（35.2%），and interpersonal communication（30.2%）. More than 60% of the respondents believed vaccine’s safety，efficacy，and immunity duration would affect its promotion，and 54.3% of them could accept vaccines at a cost less than 500 yuan. The vaccination rate of sampled female students was 15.7%. Multi -factor logistic regression analysis showed that the higher acceptable cost of the vaccine，getting the knowledge of the vaccine through interpersonal communication，the belief that HPV can be reinfected after recovery，and education level were important factors in promoting the vaccination behavior. Learning about the vaccine through media，such as television networks，negatively impacts vaccination behavior. Therefore，it is necessary to adopt comprehensive measures to improve the vaccination rate and emphasize interpersonal communication as a means of information dissemination. [ABSTRACT FROM AUTHOR]

Objective To explore the relationship between the age at first birth and mild cognitive impairment in the elderly rural women in Guizhou Province, so as to provide scientific basis for improving the current situation of their cognitive function. Methods A total of 1 653 elderly people from 5 townships in 2 counties (districts) of Guizhou Province were selected by multi-stage cluster sampling from July to August, 2019. Among them, 952 rural elderly women were investigated by questionnaire and physical examination, and the cognitive function was tested by Mini-Mental State Examination (MMSE). SPSS 26.0 software was used for univariate χ² or rank sum test, to compare the difference of the cognitive function in old age among rural womon with dfifferent dermgrophic characteristics and ages at first birth, and multivariate Logistic regression was used to analyze the influence of age at first birth on mild cognitive impairment. Results A total of 380 cases of mild cognitive impairment were detected, with a total detection rate of 39.92% (380/952). The results of univariate analysis showed that the differences in the rates of mild cognitive impairment among elderly rural women were statistically significant in terms of the following factors: age groups (χ²=45.074, P<0.001), ethnic groups (χ²=15.979, P<0.001), education level (χ²=10.394, P<0.05), BMI (χ²=18.961, P<0.001), daily exercise time (χ²=9.199, P<0.05), marital status (χ²=13.150, P<0.001), and smoking (χ²=4.318, P<0.05). In the age group of ≥ 70 years old, the detection rate of mild cognitive impairment was higher in those aged above 23 years than those aged ≤ 23 years at first birth, and the total scores of MMSE (Z=-1.961, P<0.05), immediate memory (Z=-2.108, P<0.05), and delayed memory (Z=-3.047, P<0.05) were significantly lower than the latter. The results of multivariate unconditional Logistic regression analysis in the age group ≥ 70 years old showed that the age at first birth > 23 years old (OR=1.537, 95%CI: 1.053-2.244) was a risk factor for mild cognitive impairment. Conclusion The detection rate of mild cognitive impairment is high in rural elderly women in Guizhou Province. The age at first birth may be the etiological clue of mild cognitive impairment in rural women aged 70 and above in Guizhou Province, and its causal relationship needs further study.

Objective To investigate whether sarcopenia before concurrent chemoradiotherapy is prone to grade≥3 acute adverse reactions (AAR) and shorten survival in patients with advanced esophageal squamous cell carcinoma (ESCC). Methods Data of advanced patients with pathologically diagnosed ESCC and CCRT (FP regimen) from August 2018 to July 2022 were reviewed retrospectively. Skeletal muscle mass and body composition were measured using pre-treatment CT images, and patients were divided into sarcopenia and non-sarcopenia groups. Grade≥3 AAR was diagnosed based on CTCAE5.0 and acute radiation injury criteria of the US RTOG. Risk factors for developing grade≥3 AAR were analyzed, and survival rates were calculated by Kaplan-Meier method. Results Among 132 patients with ESCC (87 in the sarcopenia group and 45 in the non-sarcopenia group), 23(17.4%) experienced grade≥3 AAR. In multivariate regression analysis, independent risk factors for grade ≥3 AAR included the following: sarcopenia (OR: 6.034, 95%CI: 1.206-30.190, P=0.029), decreased SMD (OR: 0.693, 95%CI: 0.492-0.976, P=0.036), decreased SMI (OR: 0.841, 95%CI: 0.721-0.982, P=0.028), and increased FMI (OR: 2.433, 95%CI: 1.194-4.958; P=0.014). The OS rates were 16.01 months (95%CI: 14.89-17.13) in the sarcopenia group and 19.27 months (95%CI: 14.45-24.09) in the non-sarcopenia group (χ2 =5.326, P=0.021) as well as 14.86 months (95%CI: 11.30-18.42) for patients with grade≥3 AAR and 16.67 months (95%CI: 14.91-18.43) for patients with grade 0-2 AAR (χ2 =5.47, P=0.019). Among patients with grade≥3 AAR, the OS rates were 12.13 months (95%CI: 10.15-14.11) in the sarcopenia group and 18.69 months (95%CI: 12.85-21.88) in the non-sarcopenia group (χ2 =4.466, P=0.035). Conclusion Sarcopenia, decreased skeletal muscle density, and increased fat mass are important predictors of grade≥3 AAR. The OS of patients with sarcopenia and grade≥3 AAR may be reduced.
