Objective To explore the impacts of remimazolam on intraoperative intracranial pressure(ICP)and cerebral oxygenation in patients undergoing laparoscopic lower abdominal and pelvic surgery under CO2 pneumoperitoneum combined with Trendelenburg position.Methods Eighty-eight patients scheduled to undergo laparoscopic lower abdominal and pelvic surgery were randomly assigned to the remimazolam group(n=44)and the sevoflurane group(n=44).In the remimazolam group,continuous infusion of remimazolam at a rate of 1 mg/(kg·h)was administered for anesthesia maintenance.In contrast,the sevoflurane group inhaled 2％sevoflurane.Heart rate(HR),mean arterial pressure(MAP),peak airway pressure(Peak),plateau airway pressure(Plat),end-tidal CO2(PETCO2),regional cerebral oxygen saturation(rSO2),and optic nerve sheath diameter(ONSD)of both eyes were measured and recorded at the following time points:prior to anesthesia induction(T0),5 minutes after induction(T1),10 minutes(T2),30 minutes(T3),and 60 minutes(T4)after the establishment of pneumo-peritoneum in Trendelenburg position,as well as 30 minutes after deflation in the supine position(T5).Results No significant intergroup differences were detected in HR,MAP,Peak,Plat,or PETCO2 at any time point(P>0.05).In both groups,Peak and Plat values were significantly higher at T2-T4 compared to T1(P<0.05).Regard-ing the ONSD)no intergroup differences were noted at T0 and T1(P>0.05).From T2 to T5,ONSD in both groups increased significantly relative to T0..It gradually rose with the prolongation of pneumoperitoneum and Trendelen-burg positioning and showed a slight decrease at T5(P<0.05).Specifically,at T3 and T4,the remimazolam group exhibited significantly smaller ONSD values than the sevoflurane group(P<0.05).Throughout the study,no inter-group differences in rSO2 were observed(P>0.05).Conclusion In laparoscopic lower abdominal and pelvic surgeries performed in the Trendelenburg position,intravenous anesthesia with remimazolam may be more effective in mitigating the elevation of intracranial pressure compared to sevoflurane inhalation.

OBJECTIVE: To compare the clinical efficacy of acupuncture with yin-yang regulation method versus local acupuncture in treating chronic low back pain (CLBP) in elderly patients with lumbar disc herniation (LDH), and to evaluate the changes in the multifidus muscle before and after treatment using musculoskeletal ultrasound. METHODS: A total of 128 elderly patients with CLBP due to LDH were randomly assigned to an observation group (64 cases, 2 cases dropped out) and a control group (64 cases, 2 cases dropped out). The control group received local acupuncture at bilateral L₃-L₅ Jiaji points (EX-B2), Shenshu (BL23), Dachangshu (BL25), Weizhong (BL40), Yaoyangguan (GV3), and ashi points. The observation group received acupuncture with yin-yang regulation method, which included an abdominal protocol with Baihui (GV20), Zhongwan (CV12), Qihai (CV6), Guanyuan (CV4), bilateral Tianshu (ST25), and Dahe (KI12), etc., and a lumbar protocol with Baihui (GV20), Dazhui (GV14), Jizhong (GV6), Yaoyangguan (GV3), and ashi points, etc., alternated bilaterally. Both groups were treated once every other day, three times per week, for a total of 12 sessions. The visual analogue scale (VAS) score, Oswestry disability index (ODI) score, and the indexs of musculoskeletal ultrasound multifidus muscle (resting and functional thickness and Young's modulus values) were observed before and after treatment, and the clinical efficacy was evaluated in the two groups. RESULTS: After 1 and 4 weeks of treatment, both groups showed lower VAS scores compared to baseline (P<0.05), the VAS scores in the observation group were lower than those in the control group (P<0.001). ODI scores in both groups were decreased after 1 and 4 weeks of treatment compared to baseline (P<0.05), with a further reduction at 4 weeks of treatment compared to 1 week of treatment (P<0.05); the observation group showed lower ODI score than the control group after 1 week of treatment (P<0.001). After treatment, both groups demonstrated increased resting and functional multifidus muscle thickness bilaterally compared to baseline (P<0.01), with an increased right-side thickness change rate (P<0.01), though no significant difference was observed between groups (P>0.05). Compared to baseline, after treatment, the observation group exhibited decreased Young's modulus values for bilateral resting and functional multifidus muscle (P<0.01), while the control group showed reductions only in bilateral resting and right-side functional Young's modulus values (P<0.01). After treatment, the bilateral functional Young's modulus values in the observation group were lower than that in the control group (P<0.05), and the bilateral resting and functional changes in Young's modulus values were greater in the observation group than those in the control group (P<0.01). The overall effective rate was 93.5% (58/62) in the observation group, which was higher than 79.0% (49/62) in the control group (P<0.05). CONCLUSION Acupuncture with yin-yang regulation method effectively alleviates pain, improves functional disability, increases multifidus muscle thickness, and reduces Young's modulus values in elderly patients with CLBP due to LDH, which has superior therapeutic effect compared to local acupuncture.

Objective To delve into the causal relationship between 211 gut microbiota and sepsis employing bidirectional Mendelian randomization(MR).Methods The gut microbiota genome-wide association study(GWAS)data from the Microbiome Genetics Consortium(MiBioGen,n = 18 340)and sepsis GWAS data from the FinnGen(n = 286 146)were harnessed for this study.Initially,single nucleotide polymorphisms(SNP)significantly associated with the relative abundance of 211 gut microbiota taxa were identified as instrumental variables using predefined selection criteria.The primary analytical approach was characterized by the application of inverse variance weighting(IVW),with the effect measure represented by the odds ratio(OR)to assess the results of MR.To ensure precision and reliability,analyses were conducted,including leave-one-out analysis,heterogeneity testing,and tests for pleiotropy at both coherent and incoherent levels.Results The increased risk of sepsis was associated with the elevated abundance of Collinsella[OR = 1.28,95%confidence interval(95%CI)was 1.06-1.56,P = 0.01]and Ruminococcus(OR = 1.19,95%CI was 1.05-1.35,P = 0.005).Furthermore,a protective effect against the development of sepsis was observed in association with the increased abundance of Prevotella(OR = 0.88,95%CI was 0.79-0.97,P = 0.01)and Firmicutes(OR = 0.86,95%CI was 0.75-0.996,P = 0.04).No obvious heterogeneity and irrelevant level pleiotropy were detected.Conclusion Collinsella and Ruminococcus increase the risk of sepsis,while Prevotella and Firmicutes have protective effects against sepsis.
