Objective:To investigate the correlation of serum visfatin and resistin levels with cardiometabolic index (CMI) and bone mineral density (BMD) in elderly patients with essential hypertension (EH) complicated with osteoporosis (OP) .Methods:From Feb. 2021 to Feb. 2023, 120 elderly patients with EH complicated with OP in Department of Cardiovascular Medicine, Hangzhou Hospital of Traditional Chinese Medicine were chosen (the EH complicated with OP group), and 50 healthy physical examination subjects (the NC group) and 50 EH complicated with low bone mass (the EH complicated with low bone mass group) were chosen as the control. Venous blood samples were collected from all patients, serum visfatin and resistin levels were measured, and CMI and BMD were tested. Statistical methods were used to analyze the data.Results:In EH patients with decreased bone mass or OP, the level of serum visfatin was often low, but resistin was elevated, which showed significant differences compared with that in the NC group ( F visfatin = 26.02, F resistin = 9.50, P < 0.001). The CMI in NC group was lower than that in the other two groups ( F = 52.54, P < 0.001). In terms of bone mass, BMD in NC group was higher than that in the other two groups, especially in the key parts of lumbar spine ( F=21.44, P < 0.001), femoral neck ( F=10.54, P < 0.001), Chinese triangle ( F=12.30, P < 0.001) and femoral trochanter ( F=4.87, P < 0.001), etc. BMD in EH complicated with low bone mass was also higher than that in EH complicated with OP group, including lumbar spine ( t=4.60, P < 0.001), femoral neck ( t=2.32, P=0.022), Chinese triangle ( t=4.58, P < 0.001) and femoral trochoid ( t=4.33, P < 0.001). In addition, visfatin was positively correlated with bone mass ( P < 0.05), lumbar spine ( r=0.36, P < 0.001), femoral neck ( r=0.38, P < 0.001), Chinese triangle ( r=0.28, P=0.020) and femoral trochoid ( r=0.37, P < 0.001), while resistin was negatively correlated with bone mass, lumbar spine ( r=-0.40, P < 0.001), femoral neck ( r=-0.50, P < 0.001), and femoral trochanter ( r=-0.40, P < 0.001). However, there was no significant correlation between CMI and visfatin ( r=0.06, P > 0.05) and resistin ( r=0.11, P > 0.05). Logistic analysis showed that visfatin level was a risk factor of OP in EH patients ( P < 0.001), and resistin was a protective factor ( P = 0.008) . Conclusion:Serum visfatin and resistin levels in elderly EH patients complicated with OP are correlated with BMD, suggesting that they may play an important role in disease development and treatment.

Objective:To evaluate the effects of Huoxue Bushen Formula Granules on endometrial receptivity (ER) in patients with polycystic ovary syndrome (PCOS) in ovulation induction cycle.Methods:A randomized controlled trial was conducted. Totally 50 patients with PCOS infertility in Xiyuan Hospital of China Academy of Chinese Medical Sciences from January 2019 to January 2023 were selected as the observation objects, and were divided into observation group (29 cases) and control group (21 cases) according to the random number table method. Both groups were given oral clomiphene citrate on the 5th day of menstrual cycle or progesterone withdrawal. On this basis, the observation group was given Huoxue Bushen Formula Granules on the 5th day of menstruation, while the control group was given estradiol valerate tablets. 7 days after taking medication and injecting hCG from the 10th day of menstruation, ovulation was monitored and sexual intercourse was guided. Both groups were treated for 3 menstrual cycles and followed up for 3 months. B-ultrasound was performed on 6-8 days after ovulation to obtain uterine artery pulsatility index (PI) and blood flow resistance index (RI). TCM syndrome scores were evaluated before and after treatment, and the endometrial receptivity score (Salle score) was used to evaluate the level of ER. The pregnancy and adverse reactions during treatment were recorded in the two groups.Results:After treatment, TCM syndrome score in the observation group [14.0 (13.0, 15.0) vs. 16.0 (14.5, 19.5), Z=-3.23] was lower than that of the control group ( P<0.001). The Salle score of the observation group after treatment [12.0 (9.5.0, 13.5) vs. 10.0 (9.0, 11.0), Z=-3.84] was higher than that before treatment ( P<0.001). The PI (0.68±0.52 vs. 0.81±0.06, t=18.25), RI (1.65±0.36 vs. 2.24±0.45, t=22.78) after treatment in the observation group and the control group were lower than those before treatment ( P<0.001), without statistical significance ( t values were -0.39, -1.37, respectively, P>0.05). The total effective rate of the observation group was 75.86% (22/29), and that of the control group was 71.43% (15/21), without statistical significance ( χ2=0.12, P=0.724). The pregnancy rate of the observation group was 82.76% (24/29), and that of the control group was 57.14% (12/21), with statistical significance ( χ2=3.96, P=0.046). The incidence of adverse reactions of the observation group was 3.45% (1/29) and that of the control group was 9.52% (2/21), without statistical significance ( χ2=0.80, P=0.372). Conclusion:Huoxue Bushen Formula Granules can improve the ER of PCOS infertility patients with kidney deficiency and blood stasis syndrome, improve the pregnancy rate, reduce the TCM syndrome score, improve the quality of life of patients with high safety.

Objective:To explore the value of serum activin A (ACT-A) level in early identification of moderate and severe acute pancreatitis (AP).Methods:A prospective case control study was conducted. A total of 120 patients with AP admitted to department of hepatobiliary surgery of Affiliated Nanhua Hospital of Hengyang Medical College of University of South China between October 2020 and April 2022 were recruited. According to the revised Atlanta classification, all patients were classified into mild AP group and moderate-to-severe AP group. The blood samples within 24 hours of onset were drawn, and the serum ACT-A and C-reactive protein (CRP) levels were detected by enzyme-linked immunosorbent assay (ELISA). The Ranson score and the modified CT severity index (MCTSI) were performed. Pearson correlation method was used to analyze the correlation of various parameters. The receiver operator characteristic curve (ROC curve) was plotted to analyze the predictive value of ACT-A and CRP for moderate-to-severe AP.Results:A total of 120 patients with AP were enrolled, including 83 patients with mild AP and 37 patients with moderate-to-severe AP. Serum ACT-A and CRP levels within 24 hours of onset in the moderate-to-severe AP group were significantly higher than those in the mild AP group [ACT-A (ng/L): 140.4±37.7 vs. 53.9±30.5, lg CRP: 1.42±0.91 vs. 0.77±0.70, both P < 0.01], and the Ranson score and MCTSI score were also significantly higher than those in the mild AP group (Ranson score: 5.3±1.3 vs. 1.8±1.6, MCTSI score: 5.5±1.0 vs. 2.7±1.2, both P < 0.01). Correlation analysis showed that the serum ACT-A level was positively correlated with serum CRP level, Ranson score and MCTSI score ( R2 value was 0.272, 0.841, 0.616, respectively, all P < 0.05). ROC curve analysis showed that the serum ACT-A, CRP and Ranson score had predictive value for moderate-to-severe AP. The area under the ROC curve (AUC) was 0.948 [95% confidence interval (95% CI) was 0.909-0.986], 0.711 (95% CI was 0.606-0.815), 0.946 (95% CI was 0.910-0.982), respectively. When serum ACT-A > 112.6 ng/L, the sensitivity and specificity of predicting moderate-to-severe AP were 78.38% and 96.39%, respectively, which was better than serum CRP with sensitivity and specificity of 72.92% and 66.27%, respectively, and the specificity was better than Ranson score (71.08%). Conclusion:ACT-A can be detected in the early stage of AP, and it is positively correlated with the disease severity, which can early identify moderate-to-severe AP.

Objective:To investigate the clinical difference between primary suture and T tube drainage in laparoscopic choledocholithotomy.Methods:The clinical data of 124 patients treated by laparoscopic choledocholithotomy in Suzhou Municipal Hospital from December 2018 to February 2020 were retrospectively studied. The patients were divided into the primary suture group (71 cases) and the T tube drainage group (53 cases) according to the different surgical methods, and the differences in the relevant treatment indicators were compared between the two groups.Results:There were no statistically significant differences between the two groups in gender, hypertension, diabetes mellitus, preoperative aspartate aminotransferase, preoperative alanine aminotransferase, preoperative total bilirubin, preoperative common bile duct diameter, postoperative length of stay, total cost of hospitalization, postoperative exhaust time, or postoperative biliary leakage, et al. Compared with the T tube drainage group, the primary suture group had more single choledocholithiasis before operation (33 cases vs. 15 cases), shorter operation time: (100.14 ± 38.90) h vs. (140.45 ± 54.17) h, less intraoperative bleeding: (35.70 ± 30.17) ml vs. (49.53 ± 34.58) ml, and later extraction time of Winslow hole drainage tube after operation: (7.15 ± 2.61) d vs. (5.45 ± 3.35) d, and the differences were statistically significant ( P<0.05). Conclusions:Under the condition of strictly controlling the indications of primary suture and being operated by general surgeons who can skillfully operate laparoscope and choledochoscope, laparoscopic choledocholithotomy for primary suture has better curative effect than T tube drainage, and has higher clinical application value.

Objective To study the radiation-induced mitochondrial damage and energy metabolic alteration in pancreatic exocrine cells,and to explore underlying mechanism.Methods Rat pancreatic exocrine cells (AR42 J) were divided into control group and experimental group irradiated with 6 Gy of X-rays.Mitochondrial membrane potential was detected at 24,48,72 and 96 h,the lactic acid and ATP production were detected at 24 h and 48 h,and reactive oxygen species (ROS) were detected at 24 h after irradiation.The expressions of energy metabolism related factors of HIF-1α,LDHA and PDH were detected by Western blot.The animal experiments were conducted to confirm the changes.According to random number table,eight rats were randomly divided into two groups with 4 rats in each.The irradiated group was exposed to 12 Gy of X-rays,while the control group sham-irradiated.Results Compared with the nonirradiated control group,the mitochondrial membrane potential (△Ψm) of the experimental group was progressively decreased at 24-96 h after irradiation (t =5.438-17.687,P＜0.05).The ATP content in the experimental group decreased at 24 h and 48 h (q=17.300,8.328,P＜0.05),the lactic acid increased (q =21.790,16.250,P＜0.05),and the ROS level increased (t =7.935,P＜0.05).The expressions of HIF-1α and LDHA were significantly increased,but PDH was reduced after radiation.Silencing HIF-1α by siRNA eliminated radiation-induced energy metabolic alteration.These changes were confirmed with animal experiments by locally irradiating rats.Conclusions The expression of HIF-1α is upregulated by irradiation,which leads to the change of energy metabolism as the enhancement of glycolysis pathway and the inhibition of aerobic oxidation of mitochondria in pancreatic exocrine cells.

Objective To research the clinical application value of laparoscopic bile duct exploration and the first stage suture for choledocholithiasis. Methods The clinical data of 86 patients with choledocholithiasis were analyzed retrospectively from January 2015 to January 2017 in Affiliated Suzhou Hospital of Nanjing Medical University. According to the different methods of laparoscopic bile duct exploration, they were divided into one stage suture group (observation group, 46 cases) and T tube drainage group (control group, 40 cases). Results The recovery time of gastrointestinal function, hospitalization time and hospitalization expenses in observation group were significantly better than those in control group: (22.71 ± 10.92) h vs. (35.63 ± 11.12) h, (8.4 ± 2.6) d vs. (13.5 ± 2.3) d and (12.1 ± 3.2) thousand yuan vs. (13.5 ± 4.2) thousand yuan, and there were statistical differences (P＜0.05). Conclusions Compared with T tube drainage, the first stage suture after laparoscopic common bile duct exploration has shorter hospitalization time, lower treatment cost and faster recovery. It is a safe and feasible operation method, and is worthy of popularization and application.
