Association between body mass index and physical fitness index among secondary school students in Jiangxi Province / 中国学校卫生

Objective@#To measure the body mass index (BMI) of secondary school students and analyze its association with the physical fitness index, so as to improve the physical health of middle school students.@*Methods@#Using a randomized cluster stratified sampling method, 3 813 secondary school students from six cities (Ganzhou, Ji an, Fuzhou, Nanchang, Shangrao and Jiujiang) in Jiangxi Province, China, were selected in September 2022. Questionnaire survey was administered to obtain basic information and to assess the nutritional status and physical fitness tests were conducted among secondary school students. The study was stratified by gender and age, and the Kruskal Wallis H test was used to compare the differences in the mean values of grip strength, sit-ups, standing long jump performance and strength quality among secondary school students with different BMI levels, while the correlation between BMI and strength quality index was inferred by using curve regression analysis.@*Results@#There was statistical significance in the strength quality index of middle school students with different BMI level ( H=56.79, 8.84, P <0.05). Except 13 years old group, the difference of physical fitness by BMI grade strength quality index of boys in other age groups was statistically significant ( H =22.21, 16.23, 17.98, 18.21, 8.08), while the difference of physical fitness by BMI of girls at 14 years old was statistically significant ( H =9.11)( P <0.05). The curve fitting using regression showed that the physical fitness index and BMI of middle school students (boys and girls) show an inverted U-shaped curve. The physical fitness index was higher in the middle region of BMI ( Z-score) and lower in the two end regions, while showing a decreasing trend from the middle to the two ends.@*Conclusion@#An association is found between BMI and physical fitness among secondary school students in Jiangxi Province, and wasting and overweight/obesity are negatively correlated with physical fitness. Greater attention should be paid to the nutritional status of secondary school students to ensure the normal development of physical fitness.

Characteristics of serum bile acids among healthy children in Zhejiang province / 中华儿科杂志

Objective: To characterize the serum bile acid profiles of healthy children in Zhejiang Province. Methods: A cross-sectional study was conducted on 245 healthy children who underwent imaging and laboratory biochemical tests during routine physical examinations at the Children's Hospital of Zhejiang University School of Medicine from January 2020 to July 2022. Overnight fasting venous blood samples were collected, and the concentrations of 18 individual bile acids in the serum were accurately quantitated using tandem mass spectrometry. The concentration difference of bile acid were compared between different genders and to explore the correlation between age and bile acid levels. Used the Mann-Whitney U test for intergroup comparison and Spearman test to correlation analysis. Results: A total of 245 health children with a age of 10 (8, 12) years including 125 boys and 120 girls. There were no significant differences in levels of total bile acids, primary and secondary bile acids, free and conjugated bile acids between the two gender groups (all P>0.05). The serum concentrations of ursodeoxycholic acid and glycoursodeoxycholic acid in girls were significantly higher than those in boys (199.0 (66.9, 276.5) vs. 154.7 (49.3, 205.0) nmol/L, 274.0 (64.8, 308.0) vs. 181.0 (43.8, 209.3) nmol/L, Z=2.06, 2.71, both P<0.05). The serum taurolithocholic acid in both boys and girls were positively correlated with age (r=0.31, 0.32, both P<0.05). The serum chenodeoxycholic acid and glycochenodeoxycholic acid in the boys group were positively correlated with age (r=0.20, 0.23, both P<0.05), whereas the serum tauroursodeoxycholic acid in the girls group was negatively correlated with age (r=-0.27, P<0.05), and the serum cholic acid was positively correlated with age (r=0.34, P<0.05). Conclusions: The total bile acid levels are relatively stable in healthy children in Zhejiang province. However, individual bile acids showed gender differences and were correlated with age.

Current studies of targeted alpha-particle therapy for hematologic malignancies / 中华核医学与分子影像杂志

Hematological malignancies are suitable diseases for radioimmunotherapy because of their high sensitivity to radiation and well-defined immunophenotypes. Beta emitters like 131I and 90Y have achieved some outcomes in radioimmunotherapy of hematological malignancies. Compared with beta particles, alpha particles have higher linear energy transfer, greater relative biological effects and shorter range, which give alpha particles the ability to kill tumor cells more effectively with less damage to normal tissue. This review summarizes the current studies of targeted alpha-particle therapy in hematological malignancies.

Anti-inflammatory effects of acupuncture in the treatment of chronic obstructive pulmonary disease / 中西医结合学报

Numerous randomised controlled trials have suggested the positive effects of acupuncture on chronic obstructive pulmonary disease (COPD). However, the underlying therapeutic mechanisms of acupuncture for COPD have not been clearly summarized yet. Inflammation is central to the development of COPD. In this review, we elucidate the effects and underlying mechanisms of acupuncture from an anti-inflammatory perspective based on animal studies. Cigarette smoke combined with lipopolysaccharide is often used to establish animal models of COPD. Electroacupuncture can be an effective intervention to improve inflammation in COPD, and Feishu (BL13) and Zusanli (ST36) can be used as basic acupoints in COPD animal models. Different acupuncture types can regulate different types of inflammatory cytokines; meanwhile, different acupuncture types and acupoint options have similar effects on modulating the level of inflammatory cytokines. In particular, acupuncture exerts anti-inflammatory effects by inhibiting the release of inflammatory cells, inflammasomes and inflammatory cytokines. The main underlying mechanism through which acupuncture improves inflammation in COPD is the modulation of relevant signalling pathways: nuclear factor-κB (NF-κB) (e.g., myeloid differentiation primary response 88/NF-κB, toll-like receptor-4/NF-κB, silent information regulator transcript-1/NF-κB), mitogen-activated protein kinase signalling pathways (extracellular signal-regulated kinase 1/2, p38 and c-Jun NH2-terminal kinase), cholinergic anti-inflammatory pathway, and dopamine D2 receptor pathway. The current synthesis will be beneficial for further research on the effect of acupuncture on COPD inflammation.

β-Elemene induces apoptosis and autophagy in colorectal cancer cells through regulating the ROS/AMPK/mTOR pathway / 中国天然药物

β-Elemene is an effective anti-cancer ingredient extracted from the genus Curcuma (Zingiberaceae familiy). In the present study, we demonstrated that β-elemene inhibited the proliferation of colorectal cancer cells and induced cell cycle arrest in the G2/M phase. In addition, β-elemene induced nuclear chromatin condensation and cell membrane phosphatidylserine eversion, decreased cell mitochondrial membrane potential, and promoted the cleavage of caspase-3, caspase-9 and PARP proteins, indicating apoptosis in colorectal cancer cells. At the same time, β-elemene induced autophagy response, and the treated cells showed autophagic vesicle bilayer membrane structure, which was accompanied by up-regulation of the expression of LC3B and SQSTM1. Furthermore, β-elemene increased ROS levels in colorectal cancer cells, promoted phosphorylation of AMPK protein, and inhibited mTOR protein phosphorylation. In the experiments in vivo, β-elemene inhibited the tumor size and induced apoptosis and autophagy in nude mice. In summary, β-elemene inhibited the occurrence and development of colon cancer xenografts in nude mice, and significantly induced apoptosis and autophagy in colorectal cancer cells in vitro. These effects were associated with regulation of the ROS/AMPK/mTOR signaling. We offered a molecular basis for the development of β-elemene as a promising anti-tumor drug candidate for colorectal cancer.

PXR activation impairs hepatic glucose metabolism partly via inhibiting the HNF4α-GLUT2 pathway

Drug-induced hyperglycemia/diabetes is a global issue. Some drugs induce hyperglycemia by activating the pregnane X receptor (PXR), but the mechanism is unclear. Here, we report that PXR activation induces hyperglycemia by impairing hepatic glucose metabolism due to inhibition of the hepatocyte nuclear factor 4-alpha (HNF4α)‒glucose transporter 2 (GLUT2) pathway. The PXR agonists atorvastatin and rifampicin significantly downregulated GLUT2 and HNF4α expression, and impaired glucose uptake and utilization in HepG2 cells. Overexpression of PXR downregulated GLUT2 and HNF4α expression, while silencing PXR upregulated HNF4α and GLUT2 expression. Silencing HNF4α decreased GLUT2 expression, while overexpressing HNF4α increased GLUT2 expression and glucose uptake. Silencing PXR or overexpressing HNF4α reversed the atorvastatin-induced decrease in GLUT2 expression and glucose uptake. In human primary hepatocytes, atorvastatin downregulated GLUT2 and HNF4α mRNA expression, which could be attenuated by silencing PXR. Silencing HNF4α downregulated GLUT2 mRNA expression. These findings were reproduced with mouse primary hepatocytes. Hnf4α plasmid increased Slc2a2 promoter activity. Hnf4α silencing or pregnenolone-16α-carbonitrile (PCN) suppressed the Slc2a2 promoter activity by decreasing HNF4α recruitment to the Slc2a2 promoter. Liver-specific Hnf4α deletion and PCN impaired glucose tolerance and hepatic glucose uptake, and decreased the expression of hepatic HNF4α and GLUT2. In conclusion, PXR activation impaired hepatic glucose metabolism partly by inhibiting the HNF4α‒GLUT2 pathway. These results highlight the molecular mechanisms by which PXR activators induce hyperglycemia/diabetes.

Objective:To investigate the application value of Da Vinci robotic transanal minimally invasive surgery (R-TAMIS) for local resection of rectal neoplasms.Methods:The retros-pective and descriptive study was conducted. The clinicopathological data of 7 rectal neoplasms patients undergoing R-TAMIS in Daping Hospital of Army Medical University from June 2017 to March 2021 were collected. There were 3 males and 4 females, aged (60±7)years. Observation indicators: (1) intraoperative situations; (2) postoperative recovery; (3) postoperative histopatholo-gical examinations; (4) follow-up. Follow-up was conducted using telephone interview or outpatient examination to detect readmission of patients within postoperative 30 days, tumor recurrence and metastasis and survival of patients. Follow-up was performed at postoperative 1, 3, 6 months and once every 6 months thereafter up to April 2021. Measurement data with normal distribution were represented as Mean± SD, and measurement data with skewed distribution were represented as M(range). Count data were described as absolute numbers. Results:(1) Intraoperative situations. All the 7 patients underwent R-TAMIS successfully without conversion to laparotomy or laparoscopic surgery. Of the 7 patients, 2 cases underwent full-thickness rectal resection and 5 cases underwent submucosal dissection of tumor. The rectal wounds were not sutured in 2 cases because of large lesions, and the rectal wounds were sutured with synthetic sutures in 5 cases after resection of lesions. Transanal drainage tube was placed in 2 cases and not in 5 cases. The volume of intra-operative blood loss of the 7 patients was 15(range, 2?50)mL. The total operation time of the 7 patients was (91.4±18.4)minutes, including (19.1±2.3)minutes for transanal platform placement and Da Vinci robotic surgical system installation, and (72.3±16.6)minutes for operation. There was no intraoperative complication such as urethral injury. (2) Postoperative recovery. All the 7 patients started water drinking and out-of-bed activities at postoperative day 1 and liquid food intake at postoperative day 2. The time to postoperative first flatus of the 7 patients was 1(range, 1?3)days. The two cases with transanal drainage underwent removing of transanal drainage at postoperative day 2. There was no postoperative complication and the duration of postoperative hospital stay of the 7 patients was 3(range, 3?9)days. (3) Postoperative histopathological examinations. Of the 7 patients, 3 cases had villous adenoma, 2 cases had villous adenoma combined with high grade intraepithelial neoplasia, local canceration and tumor invasion into submucosa (stage SM1), 1 case had villous adenoma combined with high grade intraepithelial neoplasia, local canceration and tumor localized in the inner mucosa (stage Tis) and 1 case had moderately differentiated adeno-carcinoma with tumor invasion into superficial muscle layer (stage T2). All the 7 patients had negative surgical margins with none of tumor cell remained in the base. (4) Follow-up. All the 7 patients were followed up for 18(range, 1?42)months. One of the 7 patients showed rectal adenocarcinoma with tumor invasion into superficial muscle layer by the postoperative histopathological examina-tion and was recommended for remedial radical surgery. The patient refused further surgery and underwent 3 courses of oral capecitabine chemotherapy. The other 6 patients did not receive postoperative chemotherapy. None of 7 patients underwent readmission within postoperative 30 days, and no patient had tumor local recurrence, distant metastasis or death during the follow-up.Conclusion:R-TAMIS for local resection of rectal neoplasms is safe and feasible for patients with rectal adenoma and early rectal cancer, with reliable short-term efficacy and short-term oncological efficacy.

Significance of serum miRNA-126 and miRNA-449a expression levels in the therapeutic efficacy and prognostic evaluation of pemetrexed combined with cisplatin for treatment of non-small cell lung cancer / 肿瘤研究与临床

Objective:To investigate the effects of serum miRNA-126 (miR-126) and miRNA-449a (miR-449a) expression levels on the efficacy and prognostic evaluation of pemetrexed combined with cisplatin in treatment of non-small cell lung cancer (NSCLC).Methods:The data of 100 NSCLC patients admitted to Wuhan Hankou Hospital from January 2016 to January 2017 were retrospectively analyzed. Before treatment, the relative expression levels of miR-126 and miR-449a in serum of both groups were detected by using real-time fluorescence quantitative polymerase chain reaction. A total of 100 healthy volunteers during the same period were treated as the control group. The efficacy was evaluated after 2 courses of treatment, and the correlation of miR-126 and miR-449a relative expression levels with clinicopathological characteristics, efficacy and prognosis of patients was analyzed.Results:The relative expression levels of serum miR-126 and miR-449a in NSCLC patients were lower than those in the control group (1.23±0.34 vs. 2.22±0.57, 0.95±0.21 vs. 2.13±0.43), and the differences were statistically significant ( F = 14.92, 24.66; all P < 0.01). There were significant differences in the relative expression levels of serum miR-126 and miR-449a in NSCLC patients with different therapeutic effects ( F = 80.65, 22.43, all P < 0.01). Spearman correlation analysis showed that the relative expression levels of serum miR-126 and miR-449a were correlated with the therapeutic effect ( ρ = 0.782, 0.618, all P < 0.01). The relative expression levels of serum miR-126 and miR-449a in NSCLC patients with different gender and age had no statistically significant difference (all P > 0.05). The relative expression levels of serum miR-126 and miR-449a in NSCLC patients with different TNM staging, pathological type, tumor diameter, degree of differentiation showed significant differences (all P < 0.05). Univariate Cox regression analysis showed TNM staging, tumor diameter, degree of differentiation, relative expression levels of serum miR-126 and miR-449a were correlated with the survival of NSCLC patients (all P < 0.05). Multivariate Cox regression analysis revealed TNM staging, tumor diameter, degree of differentiation and the relative expression levels of miR-126 and miR-449a were independent factors affecting the survival of NSCLC patients after surgery. The overall survival of patients with the high expressions of miR-126 and miR-449a was better than that of patients with the low expressions (all P < 0.05). Conclusions:The relative expression levels of serum miR-126 and miR-449a can be used as a potential serologic indicator to analyze the prognosis of NSCLC patients treated with pemetrexed combined with cisplatin.
