Objective To investigate the ameliorative effect and the related mechanism of rotating magnetic fields(RMF)on sevoflurane(SEV,a commonly used inhalational anesthetics in clinics)-induced cognitive impairments in elderly rats.Methods The cognitive functions of 24 elderly male SD rats which were allocated into 3 experimental groups(Control group,SEV group,and SEV+RMF group;n=8 per group)were assessedviawater maze testing,and the damage and repair of hippocampal neurons were detected using ELISA and Western blotting assays.Water maze testing was also conducted on additional 24 elderly male SD rats which were randomized into 3 groups(SEV group,SEV+RMF group,and SEV+autophagy inhibitor+RMF group;n=8 per group)for assessing their cognitive functions.Results Compared with SEV group,RMF intervention significantly reduced the escape latency and swimming distance in water maze test(P<0.01),while increasing the number of platform crossovers(P<0.001).RMF downregulated the serum levels of tumor necrosis factor-α,interleukin-1β,and interleukin-6 in SEV-treated rats(P<0.001),and led to remarkable reductions in both serum neuron-specific enolase and β-amyloid protein levels(P<0.001).Moreover,RMF upregulated the expressions of nerve growth factor and brain-derived neurotrophic factor in hippocampal neurons(P<0.001),suppressed the expression of apoptotic protein caspase-3 and autophagy related protein p62 in the hippocampus,and upregulate the expression of autophagy related protein Beclin-1(P<0.001).However,the administration of autophagy inhibitor 3-MA abolished the ameliorative effects of RMF on SEV-induced cognitive impairments in elderly rats(P<0.001).Conclusion RMF can effectively improves SEV-induced cognitive dysfunction in elderly rats,and this neuroprotective effect is mediated by the autophagy activation in hippocampal neurons.

With the rapid development of preimplantation genetic testing (PGT) technology in recent years, risks in clinical application have arisen at the same time. Related risks include identification of pathogenic variants for PGT, negative impact of disease for PGT on ovarian reservation in female carriers, control of ovarian stimulation, and safety of ovarian simulation in hereditary cancer gene carriers. Risk management should be performed in different steps of the PGT processes.

Objective:To observe the effects of acupuncture and moxibustion on ubiquitin-like containing PHD and RING finger domains 1(UHRF1)and DNA methyltransferase 1(DNMT1)in ectopic endometrium of rats with endometriosis(EMS). Methods:Forty Sprague-Dawley rats were randomly divided into a sham operation group with 10 rats and a model-building group with 30 rats according to body mass.EMS rat models were established in the model-building group and then were divided into a model group,an acupuncture and moxibustion group,and a progesterone group,with 10 rats in each group.All rats were fixed by a fixator.The sham operation group and the model group were given normal saline by gavage.The acupuncture and moxibustion group received acupuncture at Xuehai(SP10)and Sanyinjiao(SP6),moxibustion at Guanyuan(CV4),and gavage of normal saline.The progesterone group was given the mixed liquid made of dydrogesterone and normal saline by gavage.After 28 d of treatments,the three diameters(length,width,and height)of EMS rats'ectopic cysts were measured,the cyst volumes were calculated,the volumes before intervention were subtracted,and the difference values were used to evaluate the growth of ectopic cysts.UHRF1 and DNMT1 mRNA and protein levels in normal endometrium,eutopic endometrium,and ectopic endometrium were detected by real-time polymerase chain reaction and immunohistochemistry. Results:There was no significant difference in the ectopic cyst volume difference between the acupuncture and moxibustion group and the progesterone group(P>0.05),but they were smaller than that of the model group(P<0.05).The levels of UHRF1 and DNMT1 mRNA and protein in the ectopic endometrium of the model group were lower than those in the normal endometrium(P<0.05).The levels of DNMT1 mRNA and UHRF1 protein in the eutopic endometrium of the model group were lower than those in the normal endometrium(P<0.05).The levels of UHRF1 mRNA and protein and the level of DNMT1 protein in the ectopic endometrium of the acupuncture and moxibustion group were higher than those in the model group(P<0.05),and the level of UHRF1 mRNA was higher than that in the progesterone group(P<0.05).The level of DNMT1 mRNA in the eutopic endometrium of the acupuncture and moxibustion group was higher than that in the model group(P<0.05).The levels of UHRF1 and DNMT1 mRNA and protein in the acupuncture and moxibustion group were insignificantly different from those in the normal endometrium(P>0.05). Conclusion:Acupuncture and moxibustion may up-regulate the levels of UHRF1 mRNA and UHRF1 and DNMT1 proteins in the ectopic endometrium to the normal level so as to reduce the volume of ectopic cysts and cure EMS in rats.

Objective:To investigate the Kub stage classification of clinical renal tuberculosis and provide a reference for disease evaluation and management.Methods:A retrospective analysis was conducted on clinical data from 180 patients diagnosed with renal tuberculosis who were admitted to the First Affiliated Hospital of Dali University between January 2011 and December 2022. The 180 cases included 82 males and 98 females. The average age was (44.56±9.62) years. The tuberculosis lesions of 101 cases were on left kidney, while that of 79 cases were on right kidney. Localized/multiple lesions were observed in 118 cases, whereas extensive destruction was found in 62 cases. Moreover, the ureters were involved in 165 cases, and bladder invasion occurred in 139 cases. For patients undergoing renal preservation treatment, a comprehensive approach was employed, including ureteral stricture stenting and regular replacement of double-J stent, percutaneous nephrostomy, excision of tuberculosis lesions or partial nephrectomy, ureter reconstruction, and sigmoidocystoplasty. In cases requiring nephrectomy, either laparoscopic or open surgical approaches are utilized. Based on the results of patient imaging and endoscopy, staging and classification were performed based on the extent of tuberculosis lesions involving the kidneys (K), ureters (u), and bladder (b). The state for each above organ was divided into four stages: K stage (K 1-4), u stage (u 0-u 3), and b stage (b 0-b 3), which were then combined with the actual disease condition for further categorization. The classifications included local intrarenal type(K 1-2u 0b 0), local renal-ureteral involvement type(K 1-2u 1-2b 0-2), multiple renal-ureteral invasion type(K 3u 1-3b 0-2) and extensive destruction type(K 4u 1-3b 1-3). Further analysis was conducted on kidney preservation and subsequent disease progression among patients with different subtypes. Results:Among the 180 patients, 15 cases of local intrarenal type underwent kidney-preserving treatment. Out of these cases, 6 patients (4 patients in stage K 1u 0b 0 and 2 patients in stage K 2bu 0b 0) achieved clinical cure after receiving a pure durative anti-tuberculosis for two years. Additionally, 4 patients in stage K 2au 0b 0 attained clinical cure following anti-tuberculosis drugs combined with partial nephrectomy after two years of follow-up. Furthermore, 5 patients in stage K 2bu 0b 0 underwent ureteroscopy and D-J stent placement for regular stent replacement. The stents were subsequently removed after two years, and the patients remained clinically stable. Among the 47 cases with localized renal-ureteral involvement type, all initially underwent kidney-preserving treatment. Of these, 5 patients in stage K 1u 1b 0-2 achieved clinical remission, while disease progression necessitated nephrectomy for 3 patients in stage K 2au 1-2b 0-2 and 7 patients in stage K 2bu 1-2b 0-2. The remaining patients maintained stable conditions. Among the 56 cases of multiple renal-ureteral invasion type, stable conditions were observed in 9 out of 24 patients with stage K 3u 1-2b 0-2, while disease progression necessitated nephrectomy in 15 cases. Nephrectomy was performed for all 32 patients with stage K 3u 3b 0-2. In instances of extensive destruction type, nephrectomy was conducted for all 62 cases. The progression rates of the local renal-ureteral involvement type and the multiple renal-ureteral invasion type were 21.28% (10/47) and 48.39% (15/31), and the difference was statistically significant ( P<0.05). The kidney preservation rates of the local renal-ureteral involvement type and multiple renal-ureteral invasion type were 78.72% (37/47) and 16.07% (9/56), and the difference was statistically significant ( P<0.001). Conclusions:The Kub stage classification can provide reference to management and monitoring for renal tuberculosis. The patients in the local intrarenal type and local renal-ureteral involvement type are often treated with anti-tuberculosis plus ureteral stent implantation or partial nephrectomy or ureteral reconstruction. The patients in the multiple renal-ureteral invasion type and extensive destruction type are mostly managed by nephrectomy.

Objective: To explore the factors affecting carotid plaque formation among high-risk populations for stroke, so as to provide the reference for early intervention for carotid atherosclerosis among the populations. Methods: Permanent residents were selected from Minhang District, Shanghai Municipality using the multi-staged cluster random sampling method from April to September 2021. Basic information, family history of stroke and past medical history were collected by the Community and Township Population Screening Scale for Cardiovascular and Cerebrovascular Disease Risk Factors. High-risk populations for stroke were identified according to the Technical Specifications for Stroke Screening and Prevention. Carotid plaque status was assessed using carotid ultrasonography. Factors affecting carotid plaque formation were analyzed using a multivariable logistic regression model. Results: Among the 25 666 permanent residents surveyed, 8 459 were identified as high-risk populations for stroke, including 3 362 males and 5 097 females, with a male-to-female ratio of 0.66︰1. The median age was 66.00 (quartile range, 11.00) years. Carotid plaque were detected in 4 305 cases among high-risk population for stroke, accounting for 50.89%. Multivariable logistic regression analysis showed that advanced age (OR=1.052, 95%CI: 1.043-1.061), family history of stroke (OR=1.297, 95%CI: 1.103-1.526), hypertension (OR=1.245, 95%CI: 1.025-1.512) and diabetes (OR=1.439, 95%CI: 1.241-1.669) were associated with a higher risk of carotid plaque formation in male high-risk population for stroke, advanced age (OR=1.058, 95%CI: 1.051-1.066), lack of exercise (OR=1.138, 95%CI: 1.001-1.294), family history of stroke (OR=1.201, 95%CI: 1.062-1.357), significant overweight or obesity (OR=1.269, 95%CI: 1.127-1.430) and hypertension (OR=1.169, 95%CI: 1.003-1.362) were associated with a higher risk of carotid plaque formation in female high-risk population for stroke. Conclusion The main influencing factors for carotid plaque formation among high-risk populations for stroke include age, family history of stroke, exercise, significant overweight or obesity, hypertension and diabetes, with gender differences observed.

Hypertensive intracerebral hemorrhage(HICH)is a disease with a rapid onset,rapid progression,high mortality rate,and long-term impact on the ability to function.Non-contrast agent-based CT(NCCT)is a common method for evaluating and identifying HICH.Recent radiomics in image processing and machine learning(ML)have enabled the extraction of high-dimensional feature information from medical images,which can be used to rapidly and accurately diagnose HICH and predict its course of disease.The paper describes the application of radiomics and ML techniques in HICH diagnosis and treatment,and identifies possible directions for future research.

Objective: To investigate the core information about tuberculosis prevention and control knowledge among residents in Jiangxi Province, so as to provide insights into formulation of health education strategy for tuberculosis prevention and control. Methods: Permanent residents at ages of 15 years and older were sampled from Jiangxi Province using a multi-stage stratified cluster sampling method from January to June 2021. Participants' demographic features and access to health education for tuberculosis prevention and control were collected through questionnaires, and the awareness of core information about tuberculosis prevention and control was investigated according to Key Points for Core Information and Knowledge about Tuberculosis Prevention and Control (2016 version). Results: A total of 1 280 questionnaires were allocated, and 1 217 valid questionnaires were recovered, with an effective recovery rate of 95.08%. The respondents included 605 men (49.71%) and 612 women (50.29%), and had a mean age of (50.05±15.78) years. The overall awareness of core information of tuberculosis prevention and control was 80.46%, and the awareness rates of “Pulmonary tuberculosis is suspected and timely healthcare-seeking is required if you have cough or expectoration for more than 2 weeks”, “Pulmonary tuberculosis is mainly transmitted via respiratory tract, and everyone is likely to be infected”, “No spit anywhere, covering mouth and nose when coughing or sneezing, and wearing a mouth mask may reduce the transmission of pulmonary tuberculosis”, “Pulmonary tuberculosis is a chronic infectious disease that poses a long-term damage to health” and “Most patients may be cured and others are avoided to be infected following standard whole-process treatment” were 90.22%, 86.52%, 85.95%, 80.03% and 59.57%, respectively. There were 491 respondents that were aware of all core information about tuberculosis prevention and control (40.35%), and network was the predominant route for acquiring health education about tuberculosis prevention and control (62.08%, 586/944). Conclusions The overall awareness of core information about tuberculosis prevention and control did not achieve the target set in the 13th Five-year Plan for Tuberculosis Prevention and Control, and the awareness of tuberculosis treatment-related knowledge was low.
