BACKGROUND: Currently, more and more infertility couples are opting for combined acupuncture to improve success rate of in vitro fertilization (IVF). However, evidence from acupuncture for improving IVF pregnancy outcomes remains a matter of debate. OBJECTIVE: To quantitatively summarized the evidence of the efficacy of acupuncture among women undergoing IVF by means of systematic review and meta-analysis. METHODS: Four English (PubMed, Web of Science, EMBASE, and Cochrane Register of Controlled Clinical Trials) and Four Chinese databases (Wanfang Databases, Chinese National Knowledge Infrastructure, Chinese Science and Technology Periodical Database, and SinoMed) were searched from database inception until July 2, 2023. Randomized controlled trials (RCTs) that evaluated the acupuncture's effects for women undergoing IVF were included. The subgroup analysis was conducted with respect to the age of participants, different acupuncture types, type of control, acupuncture timing, geographical origin of the study, whether or not repeated IVF failure, and acupuncture sessions. Sensitivity analyses were predefifined to explore the robustness of results. The primary outcomes were clinical pregnancy rate (CPR) and live birth rate (LBR), and the secondary outcomes were ongoing pregnancy rate and miscarriage rate. Random effects model with I² statistics were used to quantify heterogeneity. Publication bias was estimated by funnel plots and Egger's tests. RESULTS: A total of 58 eligible RCTs representing 10,968 women undergoing IVF for pregnant success were identifified. Pooled CPR and LBR showed a signifificant difference between acupuncture and control groups [69 comparisons, relative risk (RR) 1.19, 95% confifidence intervals (CI) 1.12 to 1.25, I²=0], extremely low evidence; 23 comparisons, RR 1.11, 95%CI 1.02 to 1.21, I²=14.6, low evidence, respectively). Only transcutaneous electrical acupoint stimulation showed a positive effect on both CPR (16 comparisons, RR 1.17, 95%CI 1.06 to 1.29; I²=0, moderate evidence) and LBR (9 comparisons, RR 1.20, 95%CI 1.04 to 1.37; I²=8.5, extremely low evidence). Heterogeneity across studies was found and no studies were graded as high-quality evidence. CONCLUSION Results showed that the convincing evidence levels on the associations between acupuncture and IVF pregnant outcomes were relatively low, and the varied methodological design and heterogeneity might inflfluence the fifindings.

OBJECTIVE: To investigate the spatial patterns of the prevalence, awareness, treatment, and control rates of dyslipidemia at the provincial level in China. METHODS: A national and provincial representative cross-sectional survey was conducted among 178,558 Chinese adults in 31 provinces in mainland China in 2018-2019, using a multi-stage, stratified, cluster-randomized sampling design. Subjects, as households, were selected, followed by a home visit to collect information. Both descriptive and linear regression procedures were applied in the analyses. RESULTS: The overall prevalence of dyslipidemia was 35.6%, and wide geographic variations of prevalence, treatment, and control rates of dyslipidemia were identified among 178,558 eligible participants with a mean age of 55.1 ± 13.8 years. The highest-lowest difference regarding the provincial level prevalence rates were 19.7% vs. 2.1% for high low-density lipoprotein cholesterol, 16.7% vs. 2.5% for high total cholesterol, 35.9% vs. 5.4% for high triglycerides, and 31.4% vs. 10.5% for low high-density lipoprotein cholesterol. The treatment rate of dyslipidemia was correlated with the socio-demographic index ( P < 0.001), urbanization rate ( P = 0.01), and affordable basic technologies and essential medicines ( P < 0.001). CONCLUSION Prevailing dyslipidemia among the Chinese population and its wide geographic variations in prevalence, treatment, and control suggest that China needs both integrated and localized public health strategies across provinces to improve lipid management.

Objective: To investigate the independent and joint effects of chronotype and sleep duration on self-rated health in medical students. Methods: A cross-sectional study was conducted in 1 526 medical students selected through proportional stratified cluster random sampling from a medical university in Zhejiang province. A questionnaire survey was conducted to collect the information about their basic demographic characteristics, chronotype, sleep duration, and other lifestyle factors such as midnight snack, sedentary behavior, physical activity, meal time, and self-rated health. The independent and joint effects of chronotype and sleep duration on self-rated health were assessed by logistic regression model after controlling for confounding variables. Results: The numbers of the students with evening chronotype, neutral chronotype, and morning chronotype were 664 (43.5%), 442 (29.0%), and 420 (27.5%), respectively. Among the medical students, 42.8% (653) had poor self-rated health. Compared with those with the morning chronotype, the adjusted ORs for those with neutral chronotype and evening chronotype were 1.69 (95%CI: 1.23-2.31) and 2.43 (95%CI: 1.81-3.26), respectively, trend test P<0.001. Compared with those with sleep duration of 8 h or above per night, the adjusted ORs for those with sleep duration of 7 and ≤6 h per night were 1.40 (95%CI: 1.07-1.84) and 2.38 (95%CI: 1.69-3.37), respectively, trend test P<0.001. In the joint effect, compared with those with the morning chronotype and sleep duration of 8 h or above per night, the adjusted OR for those with evening chronotype and sleep duration of ≤6 h per night was 6.53 (95%CI: 3.53-12.09). Conclusions: Both evening chronotype and insufficient sleep were associated with increased odds of poor self-rated health in medical students, and they had joint effects. Therefore, it is necessary to promote early to bed, early to rise and adequate sleep in medical student to maintain their health.

OBJECTIVE: To compare the effect of Sheng-Xue-Xiao-Ban Capsule (SXXBC) and indirubin to the peripheral platelets of the Idiopathic thrombocytopenic purpura (ITP) model mouse. METHODS: The ITP mouse model was established by the method of passive immunization. SXXBC and indirubin were used for intervention treatment. Then the hemorrhagic phenomena of ITP mice were observed and the numbers of peripheral platelets, hemoglobin and white blood cells, bone marrow megakaryocytes and their classification and coagulation function were detected and compared. RESULTS: The improvement rate of hemorrhage in SXXBC group was 40% for small dose, 60% for medium dose and 80% for high dose, while the improvement rate of hemorrhage in indirubin group was 30% for small dose, 50% for medium dose and 60% for high dose. There was no statistically significant difference in the improvement rate of hemorrhage between the two groups (P＞0.05). Compared with the model control group, PLT and Hb increased in different doses of SXXBC and indirubin group 4th-8th day after drug intervention (P＜0.05, 0.01). However, there was no significant difference between the different doses of SXXBC group and indirubin group (P＞0.05). Compared with the model control group, the WBC in each group was significantly lower (P＜0.05, 0.01) on the 4th-8th day after drug intervention; However, there was no statistical significance between the two groups of SXXBC and indirubin (P＞0.05). Compared with the model control group, the total number of megakaryocytes in each treatment group were decreased (P＜0.05, P＜0.01), in which the number of primary megakaryocytes in the large and medium dose groups of SXXBC and indirubin were decreased (P＜0.05, 0.01), and the number of juvenile megakaryocytes in the large dose group of SXXBC and indirubin were also decreased (P＜0.05). The number of granular megakaryocytes were decreased in each intervention groups (P＜0.05, 0.01), and the number of thromocytogenic megakaryocyte was increased in the high and medium dose groups of SXXBC and indirubin (P＜0.01). The time of prothrombin was shortened in the high and medium dose groups of SXXBC and indirubin (P＜0.05), and the fibrinogen (FIB) content in the high and medium dose groups of SXXBC was close to that of the normal control group. CONCLUSION Both of the SXXBC and the indirubin standard all show good hemostatic effects. Indirubin shows a positive effect on increasing the peripheral platelet and hemoglobin in ITP model mice, regulating the immune response, reducing the total number of bone marrow megakaryocytes, increasing the thromocytogenic megakaryocyte, and increasing coagulation function.

Objective To evaluate the relationship between the failed mechanism of sevoflurane postconditioning-induced myocardial protection and the activity of dynamin-related protein 1(Drp1)in dia-betic rats. Methods Pathogen-free healthy adult male Sprague-Dawley rats, weighing 220-280 g, in which diabetes mellitus was induced by combination of high-fat and high-sucrose diet and intraperitoneal injection of streptozotoein 30 mg∕kg, were studied.Sixty rats with diabetes mellitus were divided into 5 groups(n=12 each)using a random number table: sham operation group(group Sham), myocardial ischemia∕reperfusion (I∕R)group(group I∕R), sevoflurane postconditioning group(group SP), Drp1 inhibitor mitochondrial division inhibitor-1(Mdivi-1)group(group M)and Mdivi-1 plus sevoflurane postconditioning group(group M-SP). Myocardial I∕R was induced by occluding the left anterior descending branch of the coronary artery for 30 min followed by 120 min reperfusion except for group Sham. Mdivi-1 1.2 mg∕kg was intraperito-neally injected at 15 min before ischemia in M and M-SP groups, and 2.5% sevoflurane was inhaled starting from 5 min of reperfusion in SP and M-SP groups. Blood samples were collected from the right internal jugular vein at 120 min of reperfusion for measurement of serum cardiac troponin I(cTnI)concentrations(by en-zyme-linked immunosorbent assay). Rats were then sacrificed and myocardial specimens were obtained for de-termination of the myocardial infarct size(by TTC), cell apoptosis(by TUNEL), expression of Bax, Bcl-2 and activated caspase-3(by Western blot)and nicotinamide adenine dinucleotide(NAD+)content(by spectrophotometry). Apoptosis index(AI)and Bax∕Bcl-2 ratio were calculated. Results Compared with group Sham, the percentage of myocardial infarct size, serum concentration of cTnI, AI and Bax∕Bcl-2 ratio were significantly increased, the expression of activated caspase-3 was up-regulated, and the NAD+content was decreased in the other four groups(P<0.05). Compared with group I∕R, the percentage of myocardial infarct size, serum concentration of cTnI, AI and Bax∕Bcl-2 ratio were significantly decreased, the expres-sion of activated caspase-3 was down-regulated, and the NAD+content was increased in group M-SP(P<0.05), and no significant change was found in the parameters mentioned above in SP and M groups(P>0.05). Compared with group SP, the percentage of myocardial infarct size, serum concentration of cTnI, AI and Bax∕Bcl-2 ratio were significantly decreased, the expression of activated caspase-3 was down-regulated, and the NAD+content was decreased in group M-SP(P<0.05), and no significant change was found in the parameters mentioned above in group M(P>0.05). ConclusionThe failed mechanism of sevoflurane postconditioning-induced myocardial protection may be related to the activity of Drp1 in diabetic rats.

Objective: To explore the difference of liver inflammation and fibrosis in patients with chronic hepatitis B virus (HBV) infection and chronic hepatitis C virus (HCV) infection, and to investigate the relationship between hepatic pathology and alanine aminotransferase (ALT). Methods: 57 patients with chronic HCV infection and 346 patients with chronic HBV infection who were hospitalized at Shengjing Hospital of China Medical University from January 2012 to September 2016 were enrolled. In chronic HBV infection, including 88 cases whose ALT were more than two times of upper limited of normal (ALT≥2×ULN) and 258 cases whose ALT were less than two times of upper limited of normal (ALT < 2×ULN).All the patients were underwent liver biopsy. Chronic HBV infection (ALT≥2×ULN and ALT < 2×ULN) and chronic HCV infection were compared respectively. Statistical analyses were performed using a Univariate χ²-test and Mann–Whitney U test for comparison. Correlations between variables were analyzed using Spearman's rank correlation. Results: In chronic HBV infection group, 169 cases (48.8%) had inflammation grade≥2 (G≥2), 98 cases (28.3%) had fibrosis stage≥2 (S≥2), 81 cases (23.4%) with G≥2 and S≥2.In the ALT < 2×ULN group, there were 109 cases (42.2%) with G≥2, 62 cases (24%) with S≥2, 49 cases (19%) with G≥2 and S≥2. In the ALT≥2×ULN group, 60 cases (68.2%) with G≥2, 35 cases (39.8%) with S≥2, 31 cases (35.2%) with G≥2 and S≥2. The grade of inflammation and fibrosis have significantly different between ALT≥2×ULN group and ALT < 2×ULN group (χ² = 17.66, χ² = 8.06, P < 0.01). In chronic HCV infection group, 47 cases (82.5%) with G≥2, 20 cases (35.1%) with S≥2, 20 cases (35.1%) with G≥2 and S≥2. ALT had no correlation with inflammation and fibrosis (P > 0.05). The grade of inflammation was significantly different between chronic HCV infection and chronic HBV infection whose ALT < 2×ULN (χ² = 30.19, P < 0.01) but the fibrosis have no difference (χ² = 2.96, P > 0.05). Compared with chronic HBV infection whose ALT≥2×ULN, both inflammation and fibrosis had no significantly different (χ² = 3.65, χ² = 0.32, P > 0.05 respectively). Conclusion In chronic HBV infection whose ALT < 2×ULN, about 30%-40% liver tissue with significant necroinflammation and /or fibrosis. About 80% chronic HCV infection with significant necroinflammation, and the grade of inflammation has no correlation with ALT. The grade of inflammation has significantly different between chronic HCV infection group and chronic HBV infection group whose ALT < 2×ULN.

OBJECTIVETo investigate the effects of the furin inhibitor α1-PDX on the growth, invasion, and tumorigenicity of cervical cancer cells and explore the mechanisms.

METHODSThe changes in the growth, migration and invasion of α1-PDX-transfected HeLa cells were observed using MTT assay, Boyden migration and invasion assay. The protein levels of furin and MT1-MMP were measured using Western blotting and furin activity was detected by enzyme activity assay in the transfected cells. HeLa cells were seeded subcutaneously in nude mice and the tumor volume changes were recorded.

RESULTSCompared with the control cells, α1-PDX-treated cells showed a significant growth inhibition by 18.4% at 24 h (P<0.01) with obviously lowered migration ability and cell invasiveness (P<0.01). Treatment with α1-PDX significantly reduced furin enzyme activity and MTI-MMP protein levels in HeLa cells. In nude mice, α1-PDX-treated HeLa cells exhibited a delayed and lowered tumorigenicity with reduced size of the tumors.

CONCLUSIONα1-PDX can inhibit the growth, metastasis and tumorigenicity of HeLa cells, the mechanism of which may involve a decreased furin activity and MTI-MMP expression.
