Objective To investigate the effects of quadratus lumborum block on inflammatory response and postoperative intestinal function recovery in patients undergoing laparoscopic colorectal cancer surgery. Methods A total of 60 patients scheduled for laparoscopic colorectal cancer surgery were randomly divided into two groups：quadratus lumborum block combined with general anesthesia group（group QA, n = 30）and sole general anesthesia group（group GA, n = 30）. The patients in group QA received bilateral quadratus lumborum block 30 minutes before induction of general anesthesia, and in group GA received simple general anesthesia, respectively. The concentration of serum TNF-α, IL-6 and IL-10 was measured at the following time points：5 minutes before anesthesia induction（T0）, at the completion of pneumoperitoneum establishment（T1）, 6 h（T2）and 24 h（T3）after operation. The time of first exhaust and first walking time after operation, the incidence and degree of abdominal distension were recorded. Results Compared with the group GA, the levels of inflammatory factors at all time points in the group QA were significantly lower（P < 0.05）. The time of first exhaust in the group QA was significantly shorter than that in the group GA（P < 0.05）, and the first walking time after operation in the group QA was significantly longer than that in the group GA（P < 0.05）. The incidence of postoperative abdominal distension in the group QA was significantly lower than that in the group GA（P < 0.05）. Conclusions Quadratus lumborum block before operation can significantly reduce the inflammatory response and promote the rapid recovery of intestinal function in patients undergoing laparoscopic colorectal cancer surgery.

OBJECTIVE: To probe into the mechanism of gynecological Tiaoqi Jiedu formula on chronic endometritis. METHODS: Through network pharmacology, the possible key targets and key pathways of gynecological Tiaoqi Jiedu formula on endometritis were identified. On the basis of this theory, the mouse model of endometritis was established and divided into the blank group, model group, western medicine group (levofloxacin hydrochloride), and low-dose group, medium-dose group and high-dose group (low-dose, medium-dose and high-dose gynecological Tiaoqi Jiedu formula). The network pharmacology results were verified by enzyme-linked immunosorbent assay (ELISA), real-time fluorescent quantitative polymerase chain reaction (PCR) and Western blotting. RESULTS: A total of 219 compounds and 698 corresponding targets were screened from gynecological Tiaoqi Jiedu formula. A total of 36 key targets were obtained by intersections with endometritis targets. Seventy-seven metabolic pathways were obtained by Kyoto encyclopedia of genes and genomes enrichment, including nuclear factor κB ( NF-κB) signaling pathway, advanced glycation end products (AGE)-AGE receptor signaling pathway, tumor necrosis factor signaling pathway and interleukin (IL)-17 signaling pathway. ELISA results showed that the levels of MPO, IL-6 and IL-1β in the model group were significantly higher than those in the blank group (P<0. 01). Compared with the model group, the lowdose gynecological Tiaoqi Jiedu formula group had a significant reduction in IL-6, with statistically significant difference (P<0. 05), but there was no significant difference in MPO and IL-1β between two groups (P> 0. 05). Compared with the model group, MPO, IL-6 and IL-1β in the medium-dose group, high-dose group and western medicine group decreased significantly,with statistically significant differences (P< 0. 01). The results of real-time fluorescence quantitative PCR and Western blotting showed that the gene and protein expression of P-P65 and TLR4 in the uterine tissue of the model group were significantly higher than those of the normal group, with statistically significant differences ( P < 0. 01 or P < 0. 001). Compared with the model group, the low-dose group could not significantly inhibit the expression of P-P65 and TLR4 mRNA and protein (P>0. 05), while the expression of P-P65 mRNA and TLR4 mRNA in the medium-dose group, high-dose group and western medicine group decreased significantly (P<0. 05 or P<0. 01, P<0. 001), the expression of P-P65 protein and TLR4 protein in the high-dose group and western medicine group decreased significantly (P<0. 01 or P<0. 05), the differences were statistically significant. There was no significant difference in the expression of P65 mRNA and protein in each group ( P > 0. 05). CONCLUSIONS: Gynecological Tiaoqi Jiedu formula can significantly down-regulate the levels of inflammatory factors and inhibit the expression of key genes in TLR4/ NF-κB signaling pathway in the mouse model of lipopolysaccharide (LPS)-induced endometritis, so as to achieve the purpose of anti-inflammatory and endometrial protection.

Objective To investigate the expression of fusion genes and clinical characteristics in children with acute lymphoblastic leukemia (ALL). Methods The clinical data of 341 newly diagnosed ALL children patients admitted to Henan Children's Hospital from January 2018 to December 2021 were enrolled and retrospectively analyzed. The patients were divided into positive group and negative group according to the detection of fusion genes, and the clinical characteristics, complete response rate, recurrence rate and mortality as well as other indicators were compared among different groups. Results The positive detection rate of fusion genes in 341 children with ALL was 48.1% (164/341), with a total of 15 fusion genes were detected, including TEL⁃AML1, KMT2A rearrangement, E2A⁃PBX1, BCR⁃ABL1, MEF2D rearrangement, SIL⁃TAL1, etc. There was a statistically significant difference in fusion gene expression among different age groups (P<0.001), with KMT2A rearrangement and MEF2D rearrangement more common in the <1 years old group and the >10 years old group, respectively. Hyperleukopenia was more common in children with KMT2A rearrangement+, BCR⁃ABL1+, MEF2D rearrangement+ and SIL⁃TAL1+, and the children patients with latter three types were more prone to central nervous system involvement. KMT2A rearrangement (P<0.001), BCR⁃ABL1 (P=0.001), and MEF2D rearrangement (P=0.001) were more common in the high⁃risk patients. The detection rate of gene mutation in the fusion gene positive group was significantly lower than that in the negative group (27.9% vs 53.6%, P<0.001). The Ph⁃like gene was only detected in children with acute B⁃lymphocytic leukemia, and the highest detection rate was found in the IK6 subtype, with 40% (8/20) of the IK6 subtype associated with BCR⁃ABL1. In the evaluation on the 33rd day and the 12th week of treatment, the complete remission rate of minimal residual desease (MRD) detected by polymerase chain reaction in BCR⁃ABL1+ ALL patients was lower than that of MRD detected by flow cytometry at the corresponding time point (P<0.05). The recurrence rate of the fusion gene positive group was significantly higher than that of the negative group (P<0.001), while there was no statistically significant difference in mortality between the two groups (P=0.080). The highest recurrence and mortality were observed in the KMT2Arearrangement+ group. Conclusions Childrenwith newly diagnosed ALL exhibit significant differences in clinical characteristics, treatment response rate, recurrence rate, and mortality. Monitoring MRD during treatment is an important basis for assessing risk stratification and predicting prognosis. [ABSTRACT FROM AUTHOR]

This study accurately evaluated the lateral sealing ability of faults in the Pinghu formation in the K area of the East China Sea Basin and its influence on hydrocarbon accumulation. Based on a previous analysis of the fault lateral sealing mechanism and influencing factors, starting from the fault lateral sealing type, the evaluation model and lower threshold were established for lithologic juxtaposition type and fault rock type sealing faults, respectively, in order to evaluate the fault lateral sealing property and ability. The N-1 well block was used as an example to analyze the control effect of sealing on hydrocarbon accumulation. The results indicated that the fault lateral sealing type of the Pinghu formation in the K area is mainly of the fault rock type. The fault sealing ability is affected by the clay content of the fault rock (SGR), and the lower threshold of fault lateral sealing is 15%. In this section, the SGR value of the Pinghu formation fault rocks gradually decreases from bottom to top, the sealing ability gradually weakens, and some sealed faults gradually turn open. On the plane, the lateral sealing ability of large-scale faults with long-term activity in the central and northern areas was clearly stronger than that of the southern faults. Considering that the lateral sealing property of the fault and whether hydrocarbons can accumulate in the reservoir are the two geological factors that restrict each other, the fault is laterally sealed and the reservoir is developed only when the SGR value of the fault rock is between 15% and 58 %. Therefore, fault-related traps are conducive to hydrocarbon accumulation. These research results have high theoretical and practical significance for clarifying the law of hydrocarbon accumulation and risks of reducing drilling in the K area of the East China Sea Basin.

Objective To study the effects of body surface temperature sensory block level on the maternal body temperature, labor analgesia effect, labor progress and instrument assisted delivery during epidural labor analgesia. Methods One hundred parturients with epidural labor analgesia in this hospital from May 2021 to April 2022 were randomly divided into the high level group (T6 group) and low level group (T8 group), 50 cases in each group, and 0. 075% ropivacaine + 0. 5%μg/mL sufentanil mixture liquid was used for epidural analgesia. The T6 group: the temperature level of epidural block was controlled at T6;the T8 group: the temperature level of epidural block was controlled at T8. The effect of temperature sensory block level on maternal body temperature, as well as the influences of analgesic effect, intrapartum fever, labor process time, time from rupture of membrane to delivery, oxytocin use rate and instrument midwifery rate were observed. Results The analgesic effect in the T6 group was better than that in the T8 group, but the rate of intrapartum fever and use rate of oxytocin in the T6 group were higher than those in the T8 group, and the time of labor, time from rupture of membrane to delivery in the T6 group were longer than those in the T8 group, the differences were statistically significant (P＜0. 05). There was no statistically significant difference of the instrumental midwifery rate between the two groups (P＞0. 05). Conclusion During epidural labor analgesia, the control of temperature block level at T6 is better than at T8, but which will increase the rate of intrapartum fever, prolong the duration of labor and increase the use rate of oxytocin.

To observe the clinical efficacy of Yufu Jiedu ointment in the treatment of hand foot syndrome caused by capecitabine chemotherapy in patients with colorectal cancer, so as to provide a reasonable treatment plan for clinical use. From January 2021 to May 2022, 60 patients with hand foot syndrome caused by capecitabine regimen chemotherapy for colorectal cancer diagnosed in the outpatient or inpatient department of Hunan Cancer Hospital were selected. All patients were divided into the Yufu Jiedu ointment group and the urea ointment group by coin toss method, 30 patients in each group. Yufu Jiedu ointment group was treated with Yufu Jiedu ointment, urea ointment group was treated with urea ointment, and both groups were treated continuously for 21 days. The improvement of hand foot syndrome grading, clinical efficacy, TCM syndrome score, pain visual analog score (VAS), hand foot skin reaction quality of life scale (HF-QoL) score and self rating anxiety scale (SAS) score were observed in the two groups. Yufu Jiedu ointment group was superior to urea ointment group in reducing the grade of hand foot syndrome and improving the total effective rate of treatment (P<0.05). After treatment, the scores of TCM syndromes, VAS, HF-QoL and SAS in the two groups were lower than those before treatment (P<0.05), and the scores in the Yufu Jiedu ointment group were lower than those in the urea ointment group (P<0. 05). Yufu Jiedu ointment has a definite clinical effect on the treatment of hand foot syndrome caused by capecitabine chemotherapy in colorectal cancer patients. It can effectively reduce the clinical grading of patients, reduce TCM syndrome scores, relieve pain symptoms, and improve the quality of life and anxiety of patients.It has a certain clinical application value and worthy of clinical promotion and application.
