Objective To observe the effects of lα-hydroxyvitamin D3 on renal tubular function in the patients with IgA ne phropathy(IgAN) accompanied with proteinuria.Methods Forty-eight eligible patients with IgAN were selected as the IgAN group and divided into the treatment group and control group according to the random number table method,meanwhile 30 healthy adults undergoing healthy physical examination were selected as the normal group.On the routine treatment such as maintaining the double dose of renin-angiotensin system(RAS) blocker,the treatment group took oral l α-hydroxyvitamin D3 capsule (0.5 μg,once a day);the control group continued to adopt the original treatment scheme.The treatment course lasted for 12 weeks.The changes of urinary cystatin C(Cys-C),α1-microglobulin(α1-MG),N-acetyl-β-D-glucosaminidase (NAG),24 h urinary total protein (UTP),blood urea nitrogen (BUN),serum creatinine (Scr),serum calcium (Ca),serum phosphorus (P) and intact parathyroid hormone (iPTH) in two groups were respectively compared between before and after treatment.Results Compared with the normal group,urinary Cys-C,αl-MG and NAG levels in the IgAN group were significantly increased (P＜ 0.01).After 12-week treatment,the levels of Cys-C,α1-MG and NAG were obviously declined compared with that before treatment and in the control group,the differences were statistically significant (P＜ 0.05),meanwhile the UTP level had statistical difference between the two groups after treatment and between before and after treatment in the same group (P＜0.05),but the decrease in the treatment group was more significant than that in the control group(P＜0.05).There was no statistically significant difference in BUN,Scr,Ca,P and iPTH between the two groups before and after treatment(P＞0.05).Conclusion There exists tubulointerstitial injury in IgAN with proteinuria.1α-hydroxyvitamin D3 can significantly decrease urine protein and improves the renal tubular function in the patients with IgAN.

BACKGROUND:Mouse nerve growth factor can promote the repair and regeneration of injured nerves, but current experimental research shows that the effects of different treatment methods are stil controversial.
OBJECTIVE:To evaluate the effect of mouse nerve growth factor injection via different ways on the treatment of peripheral nerve injury.
METHODS:Total y 52 patients with peripheral nerve injury were randomly assigned into two groups:experimental group (local injection of mouse nerve growth factor, n=27) and control group (systemic administration of mouse nerve growth factor, n=25). The treatment was performed once a day, and lasted for 4 weeks. Then, the clinical efficacy and recovery of neurological function were compared.
RESULTS AND CONCLUSION:The good and effective rates were 85%(n=23) and 93%(n=25) in the experimental group, while 72%(n=18) and 84%(n=21) in the control group, respectively, which were significantly better in the experimental group than the control group (P<0.05). In the experimental group, 13 cases developed transient pain at injection site, including one case of remission undergoing oral analgesics;in the control group, 12 cases had transient pain at injection site, without any treatment. The results suggest that both local and total body injection of mouse nerve growth factor are safe and effective for treatment of peripheral nerve injury, but local injection is superior to systemic administration.

Objective To investigate the effect of intervention management of hypertension and related risk factors.Methods One hundred and twenty hypertension patients are intervened in terms of blood uric acid,unbalanced diet,overweight,obesity,smoking,excessive drinking,stress and lack of physical activity.And after the medication,comparative analysis is carried out after 1 years follow-up supervision.Results There were significant differences in terms of systolic blood pressure,diastolic blood pressure,waist circumference,body mass index(BMI),fasting blood glucose,total cholesterol,low density lipoprotein (LDL),triglyceride (TG),high density lipoprotein (HDL),blood uric acid and halophilic,stroke like adaptation and cognitive ability in hypertension before and after intervention (t =10.44,8.93,3.98,2.76,7.82,5.39,3.11,3.88,2.24,2.73,5.31,5.11,6.44,3.60,6.58 respectively ;P ＜ 0.01).There weren't significant differences regarding of smoking habit,unregularly life style and stress (P ＞ 0.05).Conclusion The intervention on blood pressure and related risk factors based on changing lifestyles is proved to be with high efficiency in University Communities.

An increasing number of studies have recently indicated the important effects of gut microbes on various functions of the central nervous system.However, the underlying mechanisms by which gut microbiota regulate brain functions and behavioral phenotypes remain largely unknown. We therefore used isobaric tags for relative and absolute quantitation (iTRAQ)-based quantitative proteomic analysis to obtain proteomic profiles of the hippocampus in germ-free (GF), colonized GF, and specific pathogen-free (SPF) mice. We then integrated the resulting proteomic data with previously reported mRNA microarray data, to further explore the effects of gut microbes on host brain functions. We identified that 61 proteins were upregulated and 242 proteins were downregulated in GF mice compared with SPF mice. Of these, 124 proteins were significantly restored following gut microbiota colonization. Bioinformatic analysis of these significant proteins indicated that the glucocorticoid receptor signaling pathway and inflammation-related pathways were the most enriched disrupted pathways. This study provides new insights into the pathological mechanisms of gut microbiota-regulated diseases.

Objective:To analyze the application value of PAD (Presentation-Assimilation-Discussion) class and case teaching combined with brainstorming in the practice teaching of nursing students in the department of cardiovascular surgery.Methods:A total of 81 undergraduate nursing students who practiced in the Department of Cardiovascular Surgery, The First Affiliated Hospital of Air Force Medical University from June 2019 to April 2020 were selected as the research objects. They were randomly divided into the control group ( n=40, brainstorming teaching) and the observation group ( n=41, PAD class combined with case teaching). After one month of intervention, the teaching effect on the two groups of nursing students were evaluated through the nursing students' clinical communication ability scale, Chinese version of self-assessment of clinical reflection and reasoning (SACRR), and competency inventory for registered nurse (CIRN). And the teaching quality was assessed by the clinical nursing teacher teaching behavior assessment scale. SPSS 22.0 was used for t-test. Results:The scores of each dimension and total scores of clinical communication ability scale, Chinese version SACRR and CIRN of nursing students in the observation group were higher than those in the control group ( P<0.05). The scores of nursing teaching behavior evaluation of clinical teachers in the observation group were higher than those in the control group ( P<0.05). Conclusion:The combination of PAD class and case teaching with brainstorming can improve the clinical communication ability of nursing students in cardiovascular surgery practice, help to promote the transformation of their clinical thinking ability, improve their core competences, and play an important role in improving the teaching quality.
