Objective To explore the influence factors of the metabolic syndrome in the continuous ambu-latory peritoneal peptide(CAPD)patients. Methods A total of 104 CAPD in the PD center of the First and the Second Affiliated Hospital of Guangxi Medical University from June 2014 to June 2016 were enrolled in this study. Patients were divided into the metabolic syndrome(MS)and the non-metabolic syndrome(non-MS)group. The clinical data of patients with MS and non-MS was compared,and the influence factors of the MS in PD patients were analyzed. Results Twelve patients were diagnosed as metabolic syndrome. Significant differences in age, urine volume,serum phosphorus(P)and uric acid(UA)were observed between group MS and non-MS(P<0.05). Twenty people were overweight,with the prevalence rate of 19.2%. Compared with the normal and overweight group,age,high density lipoprotein(HDL),P and serum iron were statistically significant(P < 0.05). Thirty-one people were diagnosed as dyslipidemia,with the prevalence rate of 29.8%. Compared with the normal group, albumin,UA,BMI and D/P were statistically significant in the dyslipidemia group(P < 0.05). Ten patients were diagnosed as hyperglycemia,with the prevalence rate of 9.6 %. Significant differences in hemoglobin and the dia-stolic blood pressure(DBP)were found between the hyperglycemia group and the normal group(P < 0.05). Age and P were shown as independent risk factors for PD patients with MS(P<0.05,respectively).Conclusion The peritoneal dialysis patients were more likely to have metabolic syndrome than the normal population.Age and serum phosphorus are the factors influencing the occurrence of MS in peritoneal dialysis patients.

OBJECTIVE:The effect of post-activation potentiation on sports performance is characterized by increased muscle mobility and increased rate of muscle force generation.In this paper,Meta-analysis is used to quantitatively evaluate the effects of post-activation potentiation on sprint speed,jumping performance,and kinetic parameters(peak impulse,peak power,maximum ground reaction force,rate of force generation,etc.)after activation of relative strength levels in the lower limbs. METHODS:Electronic databases such as CNKI,WanFang,Web of Science,PubMed,and Medline were retrieved for randomized control,random crossover,or clear grouping according to the relative strength levels of the lower limbs(non-randomized controls)on the post-activation potentiation effect after activation induced by the relative strength level of the lower limbs.Free weight equipment and rapid telescopic compound exercises were used as main intervention methods in each group.The publication time of the literature was from the inception of each database until August 5,2023.Endnote software was used to manage the literature.Literature quality assessment was conducted using the PEDro scale for randomized controlled trials and ROBINS-I 2.0 standards for non-randomized controlled trials.Revman5.4 and Stata15.0 software were used to conduct publication bias evaluation,subgroup analysis and sensitivity analysis of the extracted data,and forest plots were produced for Meta-analysis. RESULTS:Eleven documents(seven randomized controlled trials and four non-randomized controlled trials)were finally included,including 216 subjects.Overall,the methodological quality of the literature was high.According to the grouping standard of 1-repetition maximum/body mass>2 for the strong group and 1-repetition maximum/body mass≤2 for the normal group,there were 99 subjects in the strong group and 117 subjects in the normal group,all of whom were male.The positive effect of post-activation potentiation on sprint performance in the strong group was significantly higher than that in the normal group[standardized mean difference(SMD)=-1.34,95%confidence interval(CI):-1.74 to-0.93,P<0.000 01];the positive effect of post-activation potentiation on vertical jump height showed no significant difference between the strong and normal group(SMD=0.30,95%CI:-0.07 to 0.66,P=0.11);the positive effect of post-activation potentiation showed no significant difference between the strong and normal groups in terms of peak impulse(SMD=-0.07,95%CI:-0.62 to 0.47,P=0.61],peak power(SMD=0.21,95%CI:-0.29 to 0.72,P=0.12),maximum ground reaction force(SMD=0.31,95%CI:-0.20 to 0.81,P=0.16)and force generation rate(SMD=0.36,95%CI:-0.11 to 0.82,P=0.39). CONCLUSION:The post-activation potentiation effect in the strong group can significantly increase the short-distance sprint speed.The potentiation effect after activation of the relative strength level of the lower limbs has similar effects on the kinematic and kinetic parameters,including explosive vertical jump height,peak impulse,peak power,maximum ground reaction force and force generation rate.

Objective: To investigate the mental health status and related factors among primary and secondary school students in western Yunnan Province, so ao to provide scientific evidences for advancing mental health education. Methods: In June 2024, a stratified cluster sampling method was employed to select 4 584 students from 18 schools across Diqing Tibetan Autonomous Prefecture, Lincang City and Baoshan City three regions in western Yunnan Province. The Mental Health Test (MHT) was used for assessment. Latent class analysis (LCA) and Logistic regression were applied for data classification and related factor analysis respectively. Results: The overall positive detection rate of MHT was 11.81%, with a mean total score of 40.50±19.25. The predominant issues were learning anxiety (58.4%), hypersensitivity tendency (31.1%), and self blame tendency (23.1%). LCA categorized students into four groups:severe psychological problems group (74.4% detection rate), learning anxiety hypersensitivity group ( 16.4 %), learning anxiety physical symptoms group (9.2%), and healthy group (0). Logistic regression revealed that compared with the healthy group, the severe problems group showed higher risks among females ( OR =3.01), junior/senior high school students ( OR =1.88/4.02), and those with authoritarian parenting ( OR =3.54); the anxiety hypersensitivity group had higher risks for females ( OR =1.87), senior high students ( OR =1.54), boarders ( OR =1.31), and authoritarian parenting recipients ( OR = 1.85 ); the anxiety physical symptoms group demonstrated increased risks among females ( OR =2.22), senior high students ( OR =2.58), and authoritarian parenting recipients ( OR =2.74), while lower risks were observed for students with parent/grandparent guardians ( OR =0.38) and non only children ( OR =0.58) (all P <0.05). Conclusions Mental health problems are prominent among students in western Yunnan, with gender, grade level, boarding status, guardian type, and parenting style being key determinants. Recommendations include strengthening mental health education, prioritizing left behind children s psychological well being and promoting healthy development.

Inorganic arsenic (iAs) is a toxic metalloid found ubiquitously in the environment. In humans, exposure to iAs can result in toxicity and cause toxicological manifestations. Arsenic trioxide (As2O3) has been used in the treatment for acute promyelocytic leukemia. The kidney is the critical target organ of trivalent inorganic As (iAsIII) toxicity. We examine if oral administration of astaxanthin (AST) has protective effects on nephrotoxicity and oxidative stress induced by As2O3 exposure (via intraperitoneal injection) in rats. Markers of renal function, histopathological changes, Na+-K+ ATPase, sulfydryl, oxidative stress, and As accumulation in kidneys were evaluated as indicators of As2O3 exposure. AST showed a significant protective effect against As2O3-induced nephrotoxicity. These results suggest that the mechanisms of action, by which AST reduces nephrotoxicity, may include antioxidant protection against oxidative injury and reduction of As accumulation. These findings might be of therapeutic benefit in humans or animals suffering from exposure to iAsIII from natural sources or cancer therapy.

OBJECTIVE：To evaluate the dissolution behavior consistency between the generic drugs and original drugs of Oxcarbazepine scored tablets ，and to compare the appearance ，the friability of the split portions ，loss of mass of the split portions as well as crystal form and morphology of raw material from different enterprises. METHODS ：HPLC method was adopted. The paddle method （rotation speed of 60 r/min，the temperature of 37.0℃）was adopted to determine accumulative dissolution rate of generic and original drugs in 4 mediums [ 0.6％ SDS hydrochloric acid solution （pH＝1.2），0.6％ SDS acetate buffer solution （pH＝4.5），0.6％ SDS phosphate buffer solution （pH＝6.8）and 0.6％ SDS water solution]. The similarity factor method was used to evaluate the similarity of dissolution curves as well as intra-batch uniformity of the split portions and whole tablets. The friability tester and electronic balance were used to determine the friability and the loss of mass of the split portions. X-ray diffractometer and scanning electron microscope were used to observe the crystal form and crystal morpho logy of the raw materials of different enterprises. RESULTS ：The linear range of oxcarbazepine was LOD was 0.04 μg/mL；RSDs of precision ，stability，reprodu- cibility and durability tests were lower than 2.0％；the reco- veries were 99.80％-101.63％（RSD＝0.37％-0.91％，n＝3）. The average cumulati ve dissolution rate of generic drug A ， generic drug B and original drug in 4 different dissolution media at 90 min were 92％，87％，90％ [0.6％ SDS hydrochloric acid solution（pH＝1.2）]；94％，94％，90％ [0.6％ SDS acetate buffer solution （pH＝4.5）]；95％，95％，91％ [0.6％ SDS phosphate buffer solution （pH 6.8）]；97％，98％，95％（0.6％ SDS water solution ）. The similarity factors of generic drug A ，generic drug B and original drug in 4 kinds of different dissolution media were 66 and 81，71 and 69，71 and 61，59 and 39. In the first 15 min，the difference of dissolution rate of split portions and whole tablets were －3％-13％，－2％-24％ and －3％-7％ for generic drug A ， generic drug B and original drug ，respectively. RSDs of accumulative dissolution rate of split portions and whole tablets were 6％-14％ and 2％-9％ for generic drug A （n＝12），4％-10％ and 1％-8％ for generic drug B （n＝12）and 2％-7％ and 2％-8％ for original drug. The appearance of the original drug was fusiform ，and the notch was deep ；the shape of the generic drug was different from each other ，and the notch of the generic drug was significantly shallower than that of original drug. The friability ， the loss of mass of the split portions for generic drug A and generic drug B ，original drug were 0.62％and 0.67％，0.12％ and 0.11％，0.08％ and 0.05％. The domestic raw materials possessed irregular lumps and debris ，while the raw materials produced by original drug enterprises possessed regular flat cuboids and regular strips with little debris ；but X-ray diffraction peaks of them were basically the same. CONCLUSIONS ：The dissolution behavior of generic drug A in 4 medium is consistent with that of the original drug；dissolution behavior of generic drug B in water containing 0.6％SDS is different from that of the original drug ；there is no significant change in the homogeneity of the original drug before and after splitting ，but the homogeneity of the generic drug A and B after splitting is lower than that of the whole tablet ；the fragility of generic drugs and loss of mass of split portions are higher than those of the original drugs ；two kinds of raw material have the same crystal form but different crystal morphology.

INTRODUCTION: Image-guided thermal ablation, preferably with ultrasonography (US), is increasingly used for treatment of small liver tumours. Perfluorobutane-contrast-enhanced US (pCEUS) is a promising tool that may allow for targeting of tumours that are otherwise imperceptible on greyscale US. Although pCEUS has been reported to be effective, the literature has been limited outside of Japan and South Korea. We aimed to provide data that supports the use of pCEUS in the thermal ablation of sonographically occult liver tumours. METHODS: We conducted a retrospective single-centre study of 35 consecutive patients who underwent pCEUS-guided ablation of 48 liver tumours with a median size of 1.2 cm. Periprocedural, one-month post-treatment and relevant follow-up imaging studies were reviewed. Electronic records were also obtained, with long-term follow-up data of 12-28 months being available for 32 patients. RESULTS: 36 (75%) tumours that were imperceptible on greyscale US became visible with pCEUS. Overall, complete tumour ablation at one month was 89%. 1 (3%) patient developed a major complication following treatment, while 6 (17%) had minor post-treatment complaints. The local tumour progression rate was 17%, with a median time of 14 months. CONCLUSION pCEUS has a role in US-guided thermal ablation of liver tumours, offering a high technical success rate that is comparable to reported data. Additional benefits may include improved procedural time and freedom from ionising radiation.

There are many chemical components in the volatile oil of Dictamni Cortex. The complex network relationship of "component-target-disease" can be revealed by using the network pharmacology method, and the mechanism of the efficacy of Dictamni Cortex can be revealed. In this study, we used Swiss Target Prediction database to predict the target of action, STRING database to build protein interaction network, and Cytoscape software to build "component-target-disease" network. The results showed that the antibacterial, anti-inflammatory and antiallergic effects of Dictamni Cortex were closely related to the components of thymol methyl ether, elemenol, anethole, and the related targets of each component were cross-linked to play a multi-target pharmacodynamic role. This study laid a foundation for the study of the effective substance basis and quality control evaluation of the Dictamni Cortex, and provided a scientific basis for further revealing its mechanism.
