Objective: To compare the effects of aerobic exercise at maximal fat oxidation (FATmax) and FATmax intensity exercise combined with resistance training (RT), and dietary restriction on the body composition, vascular endothelial function and ferroptosis in obese female university students, so as to provide a reference for exploring the mechanisms by which exercise improves vascular endothelial function. Methods: From February to May 2024, 70 obese female university students were recruited from Shanxi University and randomly divided into control group ( n =24), FATmax group ( n =24) and FATmax+RT group ( n =22). From March 4 to May 26, 2024 control group maintained their normal living habits, FATmax group performed aerobic exercise at FATmax intensity three times per week for 60 minutes per session; FATmax +RT group performed combined aerobic and resistance exercise at FATmax intensity three times per week for 60 minutes per session. The daily dietary calorie intake for all groups was determined according to resting energy expenditure. Body composition, vascular endothelial function and ferroptosis were measured before and after the intervention. Results: After 12 weeks of intervention, there were statistically significant differences in body mass, BMI, body fat, waist hip ratio and muscle mass among the three groups ( F =10.93, 5.88, 65.28, 21.14, 2.25, all P < 0.05). Compared with the control group, participants in both the FATmax group and the FATmax+RT group showed significant reductions in body weight, BMI, body fat and waist hip ratio (all P <0.05). Body fat and waist hip ratio in FATmax+RT group were lower than those in FATmax group, and muscle mass was higher than those in FATmax group and control group (both P <0.05). After 12 weeks of intervention, significant differences were observed among the three groups in serum NO, GSH, serum ferritin levels and FMD ( F = 9.14, 9.67, 4.78, 135.70, all P <0.05). Compared with the control group, the serum NO, GSH levels and FMD significantly increased, and the serum ferritin level decreased (all P <0.05) of obese female university students in FATmax group and FATmax+RT group. Serum GSH level and FMD increased and serum ferritin level decreased in FATmax +RT group when compared with FATmax group (all P <0.05). Conclusions With the same exercise training duration and frequency, FATmax intensity aerobic exercise, alone or combined with resistance and dietary restriction, can significantly improve the body composition, vascular endothelial function and inhibit ferroptosis of obese female university students. However, FATmax intensity aerobic exercise combined with resistance training has more pronounced effects.

Hypoxic pulmonary hypertension(HPH)is a kind of chronic high-altitude sickness disease,which is also the initiation link of high-altitude sickness such as pneumocardial disease and high-altitude pulmonary edema.Its main features are persistent vasoconstriction and irreversible remodeling of blood vessels.HPH has greatly impacted the health of people in the plat-eau section.As a typical representative of ethnic medicine,Zang medicine embodies the wisdom of the Zang people in their long-term struggle against diseases.Adapting to local conditions for a long time,Zang medicine has unique advantages in the treatment of HPH.By reviewing the pathogenesis of HPH and the research of single Zang medicine and the complex prescription of Zang medicine in the treatment of HPH,this article aims to provide a theoretical basis for the physiological and pathological research of HPH and to provide a reference for the clinical application of Zang medicine.

Objectives:To compare the efficacy of the combination of excimer laser coronary angioplasty(ELCA)and drug-coated balloon(DCB)for in-stent restenosis(ISR)and to evaluate the impact of neointimal tissue characteristics on treatment outcomes. Methods:A total of 96 ISR lesions from 86 patients who underwent optical coherence tomography(OCT)evaluation and DCB with or without ELCA treatment at The First Medical Center of Chinese PLA General Hospital from January 2019 to May 2023 were retrospectively analyzed.ISR lesions were divided into ELCA+DCB group(n=30)and DCB group(n=66).Additionally,ISR lesions were classified as homogeneous and non-heterogeneous patterns based on the OCT characteristics of the neointimal tissue,and the impact on acute lumen gains was compared between different ISR patterns.Acute lumen gain(ΔMLA)was defined as the changes in minimum lumen area before and after the intervention. Results:The ELCA+DCB group had a significantly greater ΔMLA than the DCB group([3.2±0.8]mm2 vs.[2.6±1.4]mm2,P=0.015).Among the ISR with a homogeneous pattern,the ΔMLA of the ELCA+DCB group was significantly greater than that of the DCB group([3.0±0.9]mm2 vs.[2.2±1.1]mm2,P=0.030).There was no significant difference in ΔMLA between the two ISR groups with the non-homogeneous pattern([3.4±0.7]mm2 vs.[3.2±1.5]mm2,P=0.533).There was no death,the rate of target lesion revascularization was similar between the patients with lesions receiving DCB treatment and patients receiving ELCA +DCB treatment(7.4%vs.4.2%,P＞0.05). Conclusions:The combination of ELCA and DCB is an effective strategy for treating ISR,which can achieve greater acute lumen gain compared to DCB treatment alone,especially for the treatment of homogenous ISR pattern characterized by OCT.

Objective To observe the effects of 12-week pilates exercise and trunk strength training on the scores of visual analog scale(VAS)and Roland-Morris disability questionnaire(RMDQ),trunk extension/flexion strength and dynamic balance of female college students with chronic non-specific low back pain(CNSLBP),so as to offer a practical-based evidence for the rehabilitation treatment for female college students with CNSLBP.Methods A total of 45 female college students with CNSLBP were randomly divided into pilates(n=22)and strength training groups(n=23).Then,the scores of VAS and RMDQ,trunk extension/flexion strength and dynamic balance were measured before and after the exercise.Results After the 12-week exercise program,compared with the pre-exercise period,the VAS and RMDQ scores in the pilates and strength training groups were significantly decreased;the extensor peak torque(EPT)at 30°/s and 90°/s angular velocities in both groups and the flexor peak torque(FPT)at 90°/s angular velocities in the Pilates group were significantly increased,and the ratio of flexor/extensor(F/E)at 30°/s and 90°/s angular velocities in both groups were significantly decreased.In the eyes-open condition,only the anterior/posterior stability index(APSI)significantly decreased in the Pilates group.With eyes closed,the APSI,stability index(SI),and medial/lateral stability index(MLSI)significantly decreased in the pilates group,and only the APSI significantly decreased in the strength training group.After 12-week exercise,compared with strength training group,the VAS scores and F/E at 30°/s and 90°/s angular velocities decreased significantly in the pilates group,and EPT at 30°/s and 90°/s angular velocities increased significantly.In the eyes-closed condition,the SI,APSI,and MLSI in the pilates group were significantly lower than those in strength training group.Conclusions Compared with strength training,pilates exercise can significantly increase and balance the trunk flexion/extension muscle strength of female college students with NSLBP,enhance dynamic balance ability under eyes-closed conditions,and improve the low back pain of CNSLBP female college students with CNSLBP.

Objective:To study the relationship between hemoglobin glycation index (HGI) and blood lipid indices such as low-density lipoprotein cholesterol (LDL-C), non-high-density lipoprotein cholesterol (non-HDL-C), and plasma atherogenic index (AIP).Methods:This cross-sectional study included 16 049 participants from the Beijing Apple Garden community between December 2011 and August 2012. The subjects were divided into three groups based on the HGI quartile: low ( n=5 388), medium ( n=5 249), and high ( n=5 412). The differences in blood lipid indicators between different HGI groups were compared and multivariate logistic regression model was established to analyze the association between HGI and dyslipidemia. And multivariate logistic regression model was established to analyze the relationship between HGI and blood lipid indicators in different glucose metabolism populations. Results:There were 16 049 participants in all (mean age: 56 years), including 10 452 women (65.1%). They were classified into normal glucose tolerance (9 093 cases), prediabetes (4 524 cases), and diabetes (2 432 cases) based on glucose tolerance status. In the general population, with the increase of HGI, LDL-C, non-HDL-C, and AIP gradually increased (all P values for trends were <0.05), and the proportion of abnormalities increased significantly ( χ2=101.40, 42.91, 39.80; all P<0.001). A multivariate logistic regression model was established, which suggested a significant correlation between HGI and LDL-C, non-HDL-C, and AIP (all P<0.05), after adjusting for factors such as age, sex, fasting blood glucose, hypertension, body mass index, smoking, and alcohol consumption. In the overall population, normal glucose tolerance group, and diabetes group, HGI had the highest correlation with non-HDL-C ( OR values of 1.325, 1.678, and 1.274, respectively); in the prediabetes group, HGI had a higher correlation with LDL-C ( OR value: 1.510); and in different glucose metabolism groups, AIP and HGI were both correlated ( OR: 1.208-1.250), but not superior to non-HDL-C and LDL-C. Conclusion:HGI was closely related to LDL-C, non HDL-C, and AIP in the entire population and people with different glucose metabolism, suggesting that HGI may be a predictor of atherosclerotic cardiovascular disease.

Esophageal squamous cell carcinoma (ESCC) is a kind of malignant tumor with high incidence and mortality in the digestive system. The aim of this study is to explore the function of lnc-ABCA12-3 in the development of ESCC and its unique mechanisms. RT-PCR was applied to detect gene transcription levels in tissues or cell lines like TE-1, EC9706, and HEEC cells. Western blot was conducted to identify protein expression levels of mitochondrial apoptosis and toll-like receptor 4 (TLR4)uclear factor kappa-B (NF-κB) signaling pathway. CCK-8 and EdU assays were carried out to measure cell proliferation, and cell apoptosis was examined by flow cytometry. ELISA was used for checking the changes in glycolysis-related indicators.Lnc-ABCA12-3 was highly expressed in ESCC tissues and cells, which preferred it to be a candidate target. The TE-1 and EC9706 cells proliferation and glycolysis were obviously inhibited with the downregulation of lnc-ABCA12-3, while apoptosis was promoted. TLR4 activator could largely reverse the apoptosis acceleration and relieved the proliferation and glycolysis suppression caused by lnc-ABCA12-3 downregulation. Moreover, the effect of lnc-ABCA12-3 on ESCC cells was actualized by activating the TLR4/NF-κB signaling pathway under the mediation of exosome. Taken together, the lnc-ABCA12-3 could promote the proliferation and glycolysis of ESCC, while repressing its apoptosis probably by regulating the TLR4/NF-κB signaling pathway under the mediation of exosome.

BACKGROUND: The hemoglobin glycation index (HGI) was developed to quantify glucose metabolism and individual differences and proved to be a robust measure of individual glycosylated hemoglobin (HbA1c) bias. Here, we aimed to explore the relationship between different HGIs and the risk of 5-year major adverse cardiovascular events (MACEs) by performing a large multicenter cohort study in China. METHODS: A total of 9791 subjects from the Risk Evaluation of Cancers in Chinese Diabetic Individuals: a Longitudinal Study (the REACTION study) were divided into five subgroups (Q1-Q5) with the HGI quantiles (≤5th, >5th and ≤33.3th, >33.3th and ≤66.7th, >66.7th and ≤95th, and >95th percentile). A multivariate logistic regression model constructed by the restricted cubic spline method was used to evaluate the relationship between the HGI and the 5-year MACE risk. Subgroup analysis between the HGI and covariates were explored to detect differences among the five subgroups. RESULTS: The total 5-year MACE rate in the nationwide cohort was 6.87% (673/9791). Restricted cubic spline analysis suggested a U-shaped correlation between the HGI values and MACE risk after adjustment for cardiovascular risk factors ( χ2 = 29.5, P <0.001). After adjustment for potential confounders, subjects with HGIs ≤-0.75 or >0.82 showed odds ratios (ORs) for MACE of 1.471 (95% confidence interval [CI], 1.027-2.069) and 2.222 (95% CI, 1.641-3.026) compared to subjects with HGIs of >-0.75 and ≤-0.20. In the subgroup with non-coronary heart disease, the risk of MACE was significantly higher in subjects with HGIs ≤-0.75 (OR, 1.540 [1.039-2.234]; P = 0.027) and >0.82 (OR, 2.022 [1.392-2.890]; P <0.001) compared to those with HGIs of ≤-0.75 or >0.82 after adjustment for potential confounders. CONCLUSIONS We found a U-shaped correlation between the HGI values and the risk of 5-year MACE. Both low and high HGIs were associated with an increased risk of MACE. Therefore, the HGI may predict the 5-year MACE risk.

Objective:To investigate the value of the decrease rate of parathyroid hormone (PTH) in predicting permanent hypoparathyroidism (PHP) in one month after operation of papillary thyroid carcinoma (PTC) .Methods:The clinical data of 322 patients with PTC who underwent at least total thyroidectomy and unilateral central lymph node dissection in the Thyroid Surgery Center of West China Hospital of Sichuan University from Jan. 2013 to Jun. 2018 were retrospectively analyzed. There were 257 women and 65 men. According to the time when PTH returned to normal, they were divided into 307 cases in the temporary hypoparathyroidism (THP) group and 15 cases in the PHP group. The decrease rate of PTH and the incidence of hypoparathyroidism in one month after operation were counted, the clinical characteristics and operation information were observed, and the risk factors of PHP were analyzed. SPSS 23.0 statistical software was used for data processing. χ 2 test and t test were used for comparison between THP and PHP. The related factors were analyzed by multivariate logistic regression. Results:307 cases of THP and 15 cases of PHP were included. Multivariate logistic analysis showed that age ≥ 55 years old ( OR, 35.193; 95% CI, 2.936 - 421.870; P=0.005) and PTH before operation closer to normal lower limit ( OR, 2.349; 95% CI, 1.161 - 4.755; P = 0.018) were independent risk factors for PHP. Patients with PHP had a higher rate of PTH decline in 1 month after operation ( OR, 373.439; 95% CI, 26.568 - 5248.983; P=0.000) . The ROC curve showed that the sensitivity and specificity of predicting PHP were 86.7% and 94.8% respectively. Conclusions:The age of patients with PTC ≥ 55 years old and PTH before operation closer to normal lower limit are independent risk factors for the occurrence of PHP. The decline rate of PTH in one month after operation which more than 73.2% can predict PHP.

OBJECTIVE: To carry out genetic testing and prenatal diagnosis for a Chinese pedigree with Lesch-Nyhan syndrome (LNS) but no specimen from the affected probands. METHODS: All affected individuals in this pedigrees were male and had deceased during childhood, with no biological specimen left. Based on their typical neurological dysfunction and tendency for self-mutilation, the diagnosis of LNS was suspected. Sanger sequencing was carried out to detect potential variant of the HPRT1 gene among female members from the pedigree. Following the identification of the pathogenic variant, prenatal diagnosis was provided for a high-risk fetus. RESULTS: The proband's mother and three other females were found to harbor heterozygous c.500_501delGGinsC (p.Arg167fs*23) variant of the HPRT1 gene, which was unreported previously. Prenatal diagnosis showed that the fetus was a male and had inherited the same pathogenic variant. CONCLUSION The c.500_501delGGinsC variant of the HPRT1 gene probably underlay the LNS in this pedigree. Above finding has provided a basis for prenatal diagnosis and genetic counseling for this pedigree.
