In the context of non-alcoholic fatty liver disease (NAFLD), characterized by dysregulated lipid metabolism in hepatocytes, the quest for safe and effective therapeutics targeting lipid metabolism has gained paramount importance. Sanhuang Xiexin Tang (SXT) and Baihu Tang (BHT) have emerged as prominent candidates for treating metabolic disorders. SXT combined with BHT plus Cangzhu (SBC) has been used clinically for Weihuochisheng obese patients. This retrospective analysis focused on assessing the anti-obesity effects of SBC in Weihuochisheng obese patients. We observed significant reductions in body weight and hepatic lipid content among obese patients following SBC treatment. To gain further insights, we investigated the effects and underlying mechanisms of SBC in HFD-fed mice. The results demonstrated that SBC treatment mitigated body weight gain and hepatic lipid accumulation in HFD-fed mice. Pharmacological network analysis suggested that SBC may affect lipid metabolism, mitochondria, inflammation, and apoptosis-a hypothesis supported by the hepatic transcriptomic analysis in HFD-fed mice treated with SBC. Notably, SBC treatment was associated with enhanced hepatic mitochondrial biogenesis and the inhibition of the c-Jun N-terminal kinase (JNK)/nuclear factor-kappa B (NF-κB) and extracellular signal-regulated kinase (ERK)/NF-κB pathways. In conclusion, SBC treatment alleviates NAFLD in both obese patients and mouse models by improving lipid metabolism, potentially through enhancing mitochondrial biogenesis. These effects, in turn, ameliorate inflammation in hepatocytes.

Objective:To investigate the effect of core strength training based on total resistance exercise (TRX) for the flying personnel with nonspecific low back pain (NLBP).Methods:Flying personnel with NLBP who recuperated in Air Force Healthcare Center for Special Services Hangzhou from October of 2019 to June of 2021 were selected. They were divided into test group and control group by simple random sampling. The test group received 4 weeks of TRX core strength training, and the control group received 4 weeks of traditional core strength training. The isokinetic muscle strength testing instrument was used to measure the muscle strength characteristics of lumbar and abdominal flexor and extensor muscle groups of the subjects. The differences in Visual Analogue Scale (VAS) and Oswestry Disability Index (ODI) were compared between 2 groups before and after training.Results:A total of 40 subjects were included with 20 cases in the test group and 20 cases in the control group, all of them were helicopter flying personnel. After training, the scores of VAS in both groups were lower than those before training ( t=22.01, 17.15, both P<0.001), and the VAS score of the test group was lower than that of the control group, with a significant difference ( t=6.55, P<0.001). After training, the ODI scores of subjects in both groups were lower than those before training ( t=32.05, 27.45, both P<0.001), and the score of the test group was lower than that of the control group, with a significant difference ( t=4.85, P<0.001). After training, the relative peak moment of lumbar and abdominal flexor and extensor muscle groups of the test group were higher than those of control group, and the differences were significant ( t=2.65, 2.41, 2.04, 3.31, P=0.026, 0.037, 0.047, 0.005). Conclusions:TRX core strength training can significantly improve the muscle strength of the lumbar and abdominal flexor and extensor muscle groups of flying personnel with NLBP, which can be used as a training program to prevent NLBP for flying personnel.

Objective:To investigate the predictive value of serum D-dimer combined with myocardial injury markers on admission for early identification of high-risk patients with acute myocarditis.Methods:Patients hospitalized for acute myocarditis in China-Japan Friendship Hospital were retrospectively enrolled from 2010 to 2021. Patients were divided into the high D-dimer level group and low D-dimer level group according to the median value of D-dimer measured by immunoturbidimetry within 24 h of admission. In-hospital adverse events were defined as death, cardiogenic shock, malignant ventricular arrhythmia and new-onset heart failure. Multivariate logistic analysis was used to explore the independent predictors of in-hospital adverse events, and receiver operating characteristic curve was used to evaluate the predictive value.Results:A total of 106 patients were analyzed, including 52 high level D-dimer patients and 54 low level D-dimer patients, with an average age of (36±16) years, and 62.3% were male. Compared with the low D-dimer level group, patients in the high D-dimer level group had lower mean systolic blood pressure [(114±21) mmHg vs. (121±14) mmHg] and diastolic blood pressure [(71±13) mmHg vs. (76±10) mmHg], higher heart rate [(97±26) beats/min vs. (79±15) beats/min], higher C-reactive protein levels [6.82 (1.61, 20.05) mg/dL vs. 1.30 (0.13, 8.93) mg/dL] and creatinine levels [86.95 (67.63, 117.83) μmol/L vs. 68.80 (60.18, 81.93) μmol/L] on admission. The proportion of patients having QRS interval >120 ms on electrocardiogram was higher in high D-dimer level group (25.0% vs. 7.4%). There was no significant difference in patients with positive myocardial injury biomarkers between the two groups. The incidence of in-hospital adverse events was higher in the high D-dimer level group (67.3% vs. 22.2%, P<0.001). Multivariate logistic analysis showed that serum D-dimer levels and elevated myocardial injury markers on admission were independently associated with in-hospital adverse events. The area under the curve (AUC) of elevated serum D-dimer level on admission for predicting in-hospital adverse events was 0.781 (95% CI: 0.690-0.873), the sensitivity was 74.5%, and the specificity was 71.2%. When combined with positive cardiac biomarkers, the AUC was 0.831 (95% CI: 0.752-0.910) with a sensitivity of 80.9% and a specificity of 78.0%. Conclusions:Elevated D-dimer level on admission can predict the risk of in-hospital adverse events in patients with acute myocarditis. The combination of cardiac injury biomarkers can improve the predictive value.

Objective:To study the strength characteristics of waist and abdominal flexor and extensor muscles of helicopter pilots in order to provide the basis for waist and abdominal strength training, endurance training and prevention of the lumbar injury.Methods:Seventy-eight male helicopter pilots, whose average age was 38.9±7.5 yrs, height was 173.3±3.0 cm, weight was 72.7±7.7 kg and BMI was 24.2±2.2 kg/m 2, were selected as subjects. Strength characteristics and work of waist and abdominal flexor and extensor muscles of helicopter pilots were detected with 2 angular velocities of 60°/s and 180°/s by using Isomed 2 000 Isokinetic Test System. The peak torques and the relative peak torques of flexor and extensor muscles were compared under same angular velocity and between different angular velocities. The difference of peak torques of flexor and extensor and the relative peak torques of flexor and extensor were compared between age groups (20-39 yrs and 40-59 yrs). Results:At the same angular velocity, the peak torque and relative peak torque of the waist and abdominal extensor muscles of helicopter pilots were higher than those of the flexor muscles ( t=5.43-8.90, P<0.01). The peak torque and relative peak torque of the waist and abdominal extensor and flexor muscles reduced with the increasing of angular velocity ( t=11.36-12.19, P<0.01). The peak torque of the waist and abdominal extensor and flexor muscles in significantly reduced with the increasing of age, but the relative peak torque of the waist and abdominal flexor and extensor muscles reduced, and the difference was statistically significant ( P<0.05 or 0.01). The qualification rate of peak moment ratio was very low, and the balance of flexor and extensor muscles was weakened. Waist and abdominal extensor muscle endurance was weaker than flexor muscle endurance, but the differences was not significant. Conclusion:It is suggested that we should scientifically strengthen the strength training of flexor muscles and the endurance training of extensor muscles, so as to improve the balance of flexor and extensor muscles, and to slow down the decline of lumbar and abdominal muscle strength with age growing.

To construct the eukaryotic expression plasmid containing the p55 gene fragment of Pneumocystis and to investigate the efficient expression in COS-7 cells, the gene fragment conaining the whole length of p55 gene was used as template to amplify this fragment with PCR and the amplified fragment was then cloned to vector pGEM-T. After enzyme digestion, p55 gene was cloned to the eukaryotic expression vector pcDNA3.1(+) to construct the plasmid pcDNA3.1(+)-582. This plasmid was then transfected to the eukaryotic expression cells COS-7 and PCR and SDS-PAGE assays were used to confirm the presence of target protein in these cells. In these ways, the eukaryotic expression vector for the p55 gene of Pneumocystis of rats was successfully constructed and expressed in COS-7 cells, thus providing the basis for further studies on the nucleic acid vaccine.

The historical surveillance results showed, there were 10 schistosomiasis cases in Huangshan City from 1994 to 2006. The survey in 2007 showed, the positive rates of blood examination for schistosomiasis in migrant workers and immigrant workers were 0.49% and 0.47% , respectively, but no schistosome-infected patients were detected by using the stool examination. An area with snails of 3 000 m~2 was found in the residence of the immigrant workers, but no infected snails were found. It is indicated that the mobile population has some impact on the transmission of schistosomiasis in the transmission-interrupted area. The surveillance and health education for the mobile population should be strengthened, and the imported infectious source should be prevented.
