Objective This study aimed to investigate the potential relationship between urinary metals copper (Cu), arsenic (As), strontium (Sr), barium (Ba), iron (Fe), lead (Pb) and manganese (Mn) and grip strength. Methods We used linear regression models, quantile g-computation and Bayesian kernel machine regression (BKMR) to assess the relationship between metals and grip strength.Results In the multimetal linear regression, Cu (β=-2.119), As (β=-1.318), Sr (β=-2.480), Ba (β=0.781), Fe (β= 1.130) and Mn (β=-0.404) were significantly correlated with grip strength (P < 0.05). The results of the quantile g-computation showed that the risk of occurrence of grip strength reduction was -1.007 (95％ confidence interval:-1.362, -0.652; P < 0.001) when each quartile of the mixture of the seven metals was increased. Bayesian kernel function regression model analysis showed that mixtures of the seven metals had a negative overall effect on grip strength, with Cu, As and Sr being negatively associated with grip strength levels. In the total population, potential interactions were observed between As and Mn and between Cu and Mn (Pinteractions of 0.003 and 0.018, respectively).Conclusion In summary, this study suggests that combined exposure to metal mixtures is negatively associated with grip strength. Cu, Sr and As were negatively correlated with grip strength levels, and there were potential interactions between As and Mn and between Cu and Mn.

The anti-inflammatory effect of simplified Zhiqin Decoction was observed by using lipopolysaccharide (LPS)-induced inflammation mouse model. The main chemical constituents and the main mechanism of action of simplified Zhiqin Decoction were predicted by network pharmacology. Animal experiments verified the anti-inflammatory mechanism of simplified Zhiqin Decoction (this experiment was approved by the Animal Experiment Ethics Committee of Southwest University, approval number: IACUC-20210825-02). Simplifying Zhiqin Decoction has a significant anti-inflammatory effect on inflammatory mice, can significantly improve the overall macro shape of mice, reduce body temperature, water intake, increase the number of autonomous activities; alleviate liver, lung, spleen, thymus inflammation and pathological damage; decrease tumor necrosis factor-α (TNF-α), interleukin (IL)-1β and IL-6, nitric oxide (NO), prostaglandin E₂ (PGE₂) content in serum and urine. The contents of serum immune factors IgG, IgA and IgM were increased. Network pharmacology predicted 66 potential anti-inflammatory active components of simplified Zhiqin Decoction involving 132 inflammatory targets, and the key anti-inflammatory signaling pathway involved PI3K/AKT, TNF, JAK-STAT, etc. Animal experiments show that simplified Zhiqin Decoction can significantly reduce the expression of JAK2/STAT-PI3K/AKT-NF-κB-TNF signaling pathway related proteins in lung tissue of inflammatory mice. The results of this study showed that simplified Zhiqin Decoction had significant anti-inflammatory effects, and its main anti-inflammatory components were quercetin, β-sitosterol, kaempferol, wogonin, stigmasterol, luteolin, neobaicalein, etc. The main mechanism of its anti-inflammatory action is that it significantly inhibits the expression of JAK2/STAT-PI3K/AKT-NF-κB-TNF signaling pathway protein.

Liver-wood and spleen-earth are in the relation of mutual promotion and mutual restriction.The liver governs the free flow of qi and the spleen governs transportation and transformation,and the coordination of their function serves as the pivot for the human body to maintain life and function well.If the function between the liver and the spleen becomes uncoordinated,the liver will fail to govern the free flow of qi and the spleen will fail to govern transportation and transformation,and then the pathological state of wood constraint and earth congestion appears,which will affect the stability of intestinal flora and the function of the nervous system,and will result in the disordered brain-gut axis mechanism and cause the occurrence and progression of menopausal hypertension.Based on years of clinical experience,Professor SONG Yin-Zhi proposes that wood constraint and earth congestion can cause menopausal hypertension,and puts forward the thoughts for preventing and treating menopausal hypertension with the therapy of soothing the liver and activating the spleen by analyzing the pathological mechanism based on the achievements of modern research.The specific measures for soothing the liver and activating the spleen include method of strengthening and activating the spleen and eliminating phlegm and resolving turbidity,method of soothing the liver and relieving constraint and supplementing qi and blood,and method of prevention before illness and regulating the heart spirit.The prescriptions of Liujunzi Decoction,Banxia Baizhu Tianma Decoction,and Xiaoyao San can be chosen separately.The application of therapy of soothing the liver and activating the spleen will enable the liver qi go smoothly and the emotions be pleased,and then the spleen and intestine function well,which will enable the stable equilibrium of intestinal flora,keep the normal lipid metabolism,and maintain the blood pressure fluctuations in the normal range.It is indicated that the treatment of menopausal hypertension can start from the liver and spleen,and the therapy of soothing the liver and activating the spleen is the starting point and is the key to the treatment of menopausal hypertension.

BACKGROUND: Polycystic ovary syndrome (PCOS) is the primary cause of anovulatory infertility, bringing serious harm to women's physical and mental health. Acupuncture may be an effective treatment for PCOS. However, systematic reviews (SRs) on the efficacy and safety of acupuncture for PCOS have reported inconsistent results, and the quality of these studies has not been adequately assessed. OBJECTIVE: To summarize and evaluate the current evidence on the efficacy and safety of acupuncture for PCOS, as well as to assess the quality and risks of bias of the available SRs. SEARCH STRATEGY: Nine electronic databases (Cochrane Library, MEDLINE, Embase, PsycINFO, CINAHL, Chinese National Knowledge Infrastructure, Wanfang Data, Chongqing VIP Chinese Science and Technology Periodical Database, and China Biology Medicine disc) were searched from their establishment to July 27, 2022. Based on the principle of combining subject words with text words, the search strategy was constructed around search terms for "acupuncture," "polycystic ovary syndrome," and "systematic review." INCLUSION CRITERIA: SRs of randomized controlled trials that explored the efficacy and (or) safety of acupuncture for treating patients with PCOS were included. DATA EXTRACTION AND ANALYSIS: Two authors independently extracted study data according to a predesigned form. Tools for evaluating the methodological quality, risk of bias, reporting quality, and confidence in study outcomes, including A Measurement Tool to Assess Systematic Reviews 2 (AMSTAR 2), Risk of Bias in Systematic Reviews (ROBIS), Preferred Reporting Items for Systematic Reviews and Meta-analyses for Acupuncture (PRISMA-A), and the Grading of Recommendations Assessment, Development and Evaluation (GRADE), were used to score the included SRs. RESULTS: A total of 885 studies were retrieved, and 11 eligible SRs were finally included in this review. The methodological quality of 2 SRs (18.18%) was low, while the other 9 SRs (81.82%) were scored as extremely low. Four SRs (36.36%) were considered to be of low risk of bias. As for reporting quality, the reporting completeness of 9 SRs (81.82%) was more than 70%. Concerning the confidence in study results, 2 study results were considered to have a high quality of evidence (3.13%), 14 (21.88%) a "moderate" quality, 28 (43.75%) a "low" quality, and 20 (31.24%) considered a "very low" quality. Descriptive analyses suggested that combining acupuncture with other medicines can effectively improve the clinical pregnancy rate (CPR) and ovulation rate, and reduce luteinizing hormone/follicle-stimulating hormone ratio, homeostasis model assessment of insulin resistance, and body mass index (BMI). When compared with medicine alone, acupuncture alone also can improve CPR. Further, when compared with no intervention, acupuncture had a better effect in promoting the recovery of menstrual cycle and reducing BMI. Acupuncture was reported to cause no adverse events or some adverse events without serious harm. CONCLUSION The efficacy and safety of acupuncture for PCOS remains uncertain due to the limitations and inconsistencies of current evidence. More high-quality studies are needed to support the use of acupuncture in PCOS.

OBJECTIVE: To access the efficacy and safety of the double-ProGlide technique for the femoral vein access-site closure in cryoballoon ablation with uninterrupted oral anticoagulants (OAC), and its impact on the electrophysiology laboratory time as well as hospital stay after the procedure in this observational study. METHODS: Patients with atrial fibrillation undergoing cryoballoon ablation with uninterrupted OAC at Department of Cardiology, Beijing Anzhen Hospital, Capital Medical University, Beijing, China from May 2019 to May 2021 were enrolled in this study. From October 2020, double-ProGlide technique was consistently used for hemostasis (ProGlide group), and before that conventional manual compression was utilized (manual compression group). The occurrence of vascular and groin complications was accessed during the hospital stay and until the three-month follow-up. RESULTS: A total of 140 participants (69.30% of male, mean age: 59.21 ± 10.29 years) were evaluated, 70 participants being in each group. Immediate hemostasis was achieved in all the patients with ProGlide closure. No major vascular complications were found in the ProGlide group while two major vascular complications were occurred in the manual compression group. The incidence of any groin complication was obviously higher in subjects with manual compression than patients with ProGlide devices (15.71% vs. 2.86%, P = 0.009). In addition, compared with the manual compression group, the ProGlide group was associated with significantly shorter total time in the electrophysiology laboratory [112.0 (93.3-128.8) min vs. 123.5 (107.3-158.3) min, P = 0.006], time from sheath removal until venous site hemostasis [3.8 (3.4-4.2) min vs. 8.0 (7.6-8.5) min, P < 0.001], bed rest time [8.0 (7.6-8.0) h vs. 14.1 (12.0-17.6) h, P < 0.001] and hospital stay after the procedure [13.8 (12.5-17.8) h vs. 38.0 (21.5-41.0) h, P < 0.001]. CONCLUSIONS Utilization of the double-ProGlide technique for hemostasis after cryoballoon ablation with uninterrupted OAC is feasible and safe, which has the clinical benefit in reducing the total electrophysiology laboratory time and the hospital stay length after the procedure.

Objective:To compare the clinical efficacy of robot-assisted versus fluoroscopy-assisted sacroiliac screw internal fixation for posterior pelvic ring fractures.Methods:China National Knowledge Infrastructure (CNKI), Wanfang Data, Chinese Medical Journal Full-text Database, PubMed, Web of Science and ScienceDirect were searched for literature on robot-assisted versus fluoroscopy-assisted sacroiliac screw internal fixation for posterior pelvic ring fractures. The search time was from the establishment of each database to March 2023. Meta-analysis was performed on the included literature. The random-effects model was used when the heterogeneity between groups was large, and the fixed-effects model was used when the heterogeneity between groups was small.Results:A total of 15 studies were included in the meta-analysis, including 465 patients in the robot-assisted group and 396 patients in the fluoroscopy-assisted group. Meta-analysis showed that the number of fluoroscopies [ SMD=-3.12, 95% CI (-4.34, -1.89), P<0.001], the number of guide pin adjustments [ SMD=-3.75, 95% CI (-6.77, -0.72), P=0.015], intraoperative blood loss [ SMD=-0.83, 95% CI (-1.18, -0.49), P<0.001], and operative time [ SMD=-2.59, 95% CI (-4.11, -1.08), P<0.001] were smaller than those in the fluoroscopy-assisted group. The rate of excellent screw implantation [ OR=10.13, 95% CI (3.67,27.98), P<0.001] of the robot-assisted was larger than the fluoroscopy-assisted group. There was no significant difference in Majeed functional score [ SMD=0.28, 95% CI (-0.0003, 0.55), P=0.050] and fracture healing time [ SMD=-0.14, 95% CI (-0.46, 0.17), P=0.367] between the two groups. Conclusion:Robot-assisted percutaneous sacroiliac screw fixation for posterior pelvic ring fractures has the advantages of less fluoroscopy, less guide pin adjustment, less intraoperative blood loss, shorter operation time, and higher rate of excellent screw position. However, there is no difference in Majeed score and fracture healing time between robot-assisted percutaneous sacroiliac screw fixation and fluoroscopy-assisted percutaneous sacroiliac screw fixation.
