Comparison of Efficacy Between Prone Split-leg Position and Traditional Prone Position Percutaneous Nephrolithotomy for Upper Urinary Tract Stones / 中国微创外科杂志

Objective To explore the application effect of prone split-leg position in percutaneous nephrolithotomy(PCNL).Methods A total of 79 patients with upper urinary tract stones who underwent surgery in our department from July 2021 to July 2022 were selected.According to the surgical position,the patients were divided into prone split-leg position group(n =35)and traditional prone position group(n =44).The two groups were compared regarding operation time,intraoperative blood loss,postoperative and preoperative hemoglobin changes,postoperative complications,one-stage stone free rate,and duration of hospitalization.Results The prone split-leg position group had significantly shorter operative time and higher one-stage stone free rate than those in the traditional prone position group[(69.6±20.7)min vs.(90.5±35.3)min,t =-3.280,P =0.002;97.1%(34/35)vs.79.5%(35/44),χ2 =3.984,P =0.037].There were 1 case of infection,3 cases of fever,and 1 case of bleeding in the prone split-leg position group,while 4 cases of postoperative fever and 2 cases of bleeding in the traditional prone position group,without significant difference in the incidence of complications between the two groups(χ2 =0.000,P =1.000).There were no statistical differences in intraoperative blood loss,number of working channel,hemoglobin changes,and duration of hospitalization(P>0.05).Conclusion Prone split-leg position PCNL can shorten the operation time,improve the one-stage stone free rate,and will not increase the risk of postoperative complications,with good safety and effectiveness.

Correlation analysis between sleep quality and carotid atherosclerosis in low and moderate risk individuals for cardiovascular and cerebrovascular diseases / 上海交通大学学报（医学版）

Objective·To explore the relationship between sleep quality and carotid atherosclerosis in the population with low or moderate risk of cardiovascular and cerebrovascular diseases.Methods·Based on the population-based cohort study of chronic diseases in Xinjiang,the researchers selected residents aged 35-75 from two fixed communities in Urumqi and Korla,in Northern and Southern Xinjiang,respectively,using a two-stage random cluster sampling method from July 2019 to September 2021.In the population without a history of coronary heart disease and cerebrovascular events,the prediction model for atherosclerotic cardiovascular disease(ASCVD)risk in China(China-PAR)was used to evaluate the risk of cardiovascular and cerebrovascular diseases.Low and moderate risk population of cardiovascular and cerebrovascular diseases were included.Participants completed physical examinations,questionnaires[including the Risk Factors Assessment Scale of Cardiovascular and Cerebrovascular Diseases in Xinjiang,Pittsburgh Sleep Quality Index(PSQI),International Physical Activity Questionnaire(IPAQ),and Food Frequency Questionnaire],cardiovascular and metabolic biochemical examinations,and carotid color doppler.Carotid intima-media thickness(CIMT)and plaque formation were used to determine the carotid atherosclerosis of the study subjects.Multivariate Logistic regression model and restricted cubic spline(RCS)were used to analyze the relationship between sleep quality and carotid intima-media thickening/plaque formation in the population with low and moderate risk of cardiovascular and cerebrovascular diseases.Results·A total of 1 528 subjects were included in the study,the mean age was(49.4±8.2)years,and 685(44.8％)were male.In the included population,there were 581(38.0％)subjects with carotid intima-media thickening and 305(20.0％)subjects with carotid plaque formation.Among them,intima-media thickening and plaque formation both occurred in 154(10.1％)people.Therefore,the prevalence of carotid atherosclerosis was 47.9％(732 subjects).Compared with the group without carotid artery thickening,the group with carotid intima-media thickening/plaque formation had higher levels of general cardiovascular and cerebrovascular risk factors,including age,male ratio,blood lipid levels and obesity,and higher PSQ1 sleep score[(7.06±2.13)vs(7.43±2.51),P=0.001].The proportion of patients with poor sleep quality was higher(6.5％vs 12.1％,P=0.001).Multivariate Logistic regression analysis showed that poor sleep quality was an independent risk factor for carotid atherosclerosis[adjusted OR(aOR)=1.22,95％CI 1.004-1.492,P=0.040].RCS analysis suggested that PSQI and the risk of carotid atherosclerosis showed a positive linear correlation,that is,the worse quality of sleep,the higher risk of carotid atherosclerosis.Conclusion·Although the traditional metabolic risk factors are at a low risk level,the prevalence of carotid atherosclerosis is high and poor sleep quality is an independent risk factor for carotid atherosclerosis in the low and moderate risk population of cardiovascular and cerebrovascular diseases.

Total triterpenes of Euphorbium alleviates rheumatoid arthritis via Nrf2/HO-1/GPX4 pathway / 中国中药杂志

This study aims to investigate the effect and mechanism of total triterpenes of Euphorbium in treating rheumatoid arthritis(RA). The rat model of RA was established with Freund's complete adjuvant(FCA). Male rats were randomly assigned into control, model, Tripterygium glycosides(7.5 mg·kg~(-1)), and low-, medium-, and high-dose total triterpenes of Euphorbium(32, 64, and 128 mg·kg~(-1), respectively) groups, with 10 rats in each group. In other groups except the control group, 0.2 mL FCA was injected into the right hind toe. Rats in the intervention groups were administrated with corresponding drugs by gavage, and the control group and the model group with the same volume of 0.5% CMC-Na solution once a day. During the treatment period, the swelling degree of the hind paw was measured and the arthritis was scored until day 30. At the end of drug administration, the pathological changes of the joint tissue were observed by hematoxylin-eosin staining. The content of malondialdehyde(MDA), glutathione(GSH), and Fe~(2+) and the activity of superoxide dismutase(SOD) in the joint tissue were measured by biochemical colorimetry. RT-PCR was performed to determine the mRNA levels of nuclear factor erythroid 2-related factor 2(Nrf2), glutathione peroxidase 4(GPX4), and acyl-CoA synthetase long chain family member 4(ACSL4) in the joint tissue. Western blot was employed to determine the protein levels of Nrf2, Kelch-like ECH-associated protein 1(Keap1), heme oxygenase-1(HO-1), NAD(P)H quinone oxidoreductase 1(NQO1), SOD2, GPX4, and ACSL4 in the joint tissue. The results showed that the treatment with Tripterygium glycosides(7.5 mg·kg~(-1)) and total triterpenes of Euphorbium(32, 64, and 128 mg·kg~(-1)) alleviated the swelling degree of bilateral hind limbs, decreased the arthritis score, reduced joint tissue lesions and the content of MDA and Fe~(2+) in the joint tissue, and increased GSH content and SOD activity. Furthermore, the interventions up-regulated the protein and mRNA levels of Nrf2 and GPX4, down-regulated the protein and mRNA levels of ACSL4, and up-regulated the protein levels of Keap1, NQO1, HO-1, and SOD2 in the Nrf2/HO-1/GPX4. In summary, the total triterpenes of Euphorbium can treat RA by inhibiting lipid peroxidation and abnormal ferroptosis, which may involve the Nrf2/HO-1/GPX4 signaling pathway.

Objective: To explore the relationship between sleep/physical activity and metabolic syndrome (MS) in urban population of Xinjiang. Methods: This is a prospective, cross-sectional study. From July 2019 to September 2021, a two-stage random sampling method was used to randomly select residents aged 30-74 years from two communities in Urumqi of northern Xinjiang and Korla of southern Xinjiang. General situation questionnaire, Pittsburgh Sleep Quality Index Scale (PSQI) survey, International Physical Activity Questionnaire (IPAQ) survey, physical examination, physiological and biochemical indicators were obtained and analyzed. The dose-response curves of healthy sleep score and physical activity with metabolic syndrome were plotted using restricted cubic spline curves. Multivariate logistic regression model was used to analyze the independent and combined effects of sleep quality and physical activity on MS risk. Results: A total of 10 209 participants were included. The mean age of the subjects was (47.1±9.1) years, and males accounted for 51.3% (5 275/10 209). The prevalence of MS was significantly associated with the healthy sleep score and physical activity. Compared to the subjects with healthy sleep, OR (95%CI) of MS with intermediate, and poor sleep were 1.20(1.06-1.35), 1.23(1.04-1.45), respectively. Compared to the subjects with high physical activity, OR (95%CI) of MS with medium, low physical activity was 1.34(1.15-1.56), 1.42(1.19-1.70), respectively. There was a significant interaction between sleep and physical activity in MS (P for interaction=0.002). Compared to the subjects with high physical activity and healthy sleep, OR (95%CI) of MS with poor sleep and high physical activity was 2.03 (1.24-3.33, P for trend=0.016). Conclusion: Poor sleep quality and lack of physical activity are not only independent risk factors for an increased risk of MS but also have a combined effect with an increased risk of MS.
