Objective To observe the clinical efficacy of yang-supplementing fire moxibustion in treating chronic obstructive pulmonary disease (COPD) in stable stage. Method Totally 120 COPD patients of yang deficiency type in stable stage were divided into 3 groups by the random number table, a yang-supplementing fire moxibustion group (yang-supplementing group), a dry mild moxibustion group (mild moxibustion group), and a regular Western medication group (regular group), 40 cases in each group, and 30-day treatment was taken as a course. They were treated and observed for a course, followed by a 3-month follow-up study. The pulmonary function indexes, yang-deficiency signs, quality of life, and comprehensive therapeutic efficacy were observed in the three groups. Result After treatment, the pulmonary function indexes, yang deficiency signs, quality of life, and comprehensive therapeutic efficacy were significantly improved in the three groups (P<0.01); the percent of predicted forced expiratory volume in one second (FEV1%) and yang deficiency signs were significantly improved after intervention in the mild moxibustion group (P<0.05); meanwhile, the quality of life was also significantly improved after intervention in the mild moxibustion group and regular group (P<0.01); the therapeutic efficacy of the yang-supplementing group was better than that of the mild moxibustion group and regular group, and the efficacy of the mild moxibustion group was better than that of the regular group. Conclusion Yang-supplementing fire moxibustion can improve the pulmonary function, postpone the progressive decrease of pulmonary function, significantly improve the yang deficiency constitution, enhance the quality of life and comprehensive therapeutic efficacy in treating yang-deficient COPD patients in stable stage.

BACKGROUND:Although the nickel-titanium occluder in the treatment of congenital heart disease has a better clinical effect, arrhythmia wil be more likely to develop in late stage. OBJECTIVE:To investigate the effect of nickel-titanium wire on expression of sarcoplasmic reticulum Ca~(2+)-ATPase and ryanodine receptor of rat myocardial cels. METHODS:Thirty Sprague-Dawley rats were obtained and randomly divided into two groups: experimental and control groups. The nickel-titanium wire was implanted to the apex of heart of rats in the experimental group. Rats in the control group received no special treatment. Rat mycardial cels were harvested at the 1th, 3rdand 6th months after operation. The gene and protein expressions of sarcoplasmic reticulum Ca~(2+)-ATPase and ryanodine receptor of rat myocardial cels were detected using RT-PCR and immunohistochemistry, respectively. The inflammatory reactions were detected using hematoxylin-eosin staining. RESULTS AND CONCLUSION:After the nickel-titanium wire was implanted into the rat myocardium, inflammatory reaction was induced by inflammatory cel infiltration in the experimental group, with hyperplasia of fibrous tissue. The inflammatory reaction gradualy disappeared as the implanted time extended. No inflammatory cel infiltration was visible in the control group. There was no significant difference in the gene and protein expressions of sarcoplasmic reticulum Ca~(2+)-ATPase and ryanodine receptor of rat myocardial cels at different time points after operation between these two groups. It showed that nickel-titanium wire had no influence on the expressions of sarcoplasmic reticulum Ca~(2+)-ATPase and ryanodine receptor of rat myocardial cels. These results suggest that nickel-titanium occluder-related arrhythmia may have little relationship with abnormal protein expression of sarcoplasmic reticulum Ca~(2+)-ATPase and ryanodine receptor.

BACKGROUND: Insufficient bone mass in the posterior maxilla region often increases the difficulty of dental implantation. The application of maxillary sinus floor elevation successfully solves this problem. In the surgery bone grafting can be used to obtain sufficient bone mass. However, nonuse of graft materials can shorten the cycle of patient's treatment and reduce trauma and cost. OBJECTIVE: Combining the latest relevant research trends, to review the advances in the study of maxillary sinus floor elevation with and without bone grafting. METHODS: The first author searched PubMed, VIP, WanFang and CNKI databases using computer for relevant articles published from January 1985 to August 2018. The key words were "dental implant, maxillary sinus, bone augmentation, bone substitute" in English and Chinese, respectively. Finally, 78 articles were included in result analysis after screening and summarizing. RESULTS AND CONCLUSION: Ideal results can be achieved in the maxillary sinus floor elevation with or without simultaneous bone grafting In addition, the nonuse of grafting materials have the advantages of simplifying surgical procedures, shortening treatment cycles, reducing trauma and pain, reducing treatment costs, reducing complications and failure rates, thus gaining the favor of doctors and patients. Therefore, the maxillary sinus floor elevation without simultaneous bone grafting will be the primary choice of the doctors engaged in dental implantation in the future.

ObjectiveTo investigate the mental health condition of college students during the Corona Virus Disease 2019 （COVID-19） ， and to provide accurate basis for their psychological intervention. MethodsThrough the way of electronic questionnaire， questionnaire star as tools， random investigation of college students in a university in Sichuan. Self-rating Anxiety Scale （SAS）， Self-rating Depression Scale （SDS） and Somatization Symptom Scale （SSS） were used to evaluate their anxiety， depression and somatization symptoms. At the same time， a self-made questionnaire was used to investigate their styles of help seeking， and the relationships between them. ResultsA total of 551 valid questionnaires were collected， including 4.90% of anxiety symptoms， 28.68% of depression and 17.97% of somatization symptoms. In terms of somatization， the detection rate was higher in urban college students than those in rural （23.35% vs. 13.27%， P<0.05）， non-medical students was higher than medical students （21.40% vs. 13.89%， P<0.05）. Women's SSS score was higher than men's ［（26.51 ± 5.44） vs. （25.27 ± 5.78）］， urban college students' SSS score were higher than rural ［（26.69 ± 5.98） vs. （25.38 ± 5.12）］， and non-medical students’ SSS score were higher than medical students ［（26.65 ± 5.59） vs. （25.21 ± 5.45）］， and the differences were statistically significant （P<0.05）. Partial correlation analysis showed that SSS score was positively correlated with SAS score （r=0.110， P=0.010） and negatively correlated with SDS score （r=-0.087， P=0.042）. The top three common ways of help-seeking pattern among college students were self-regulation （81.85%）， talking to family or friends （70.78%） and offline psychological counseling （28.31%）. ConclusionUnder the COVID-19 epidemic， the detection rate of depressive symptoms and somatization symptoms of college students is high. The detection rate of somatization symptoms of female， urban and non-medical college students is high. Self-regulation and talking to family or friends are the main psychological styles of help seeking for college students.

BACKGROUND: There is little published evidence about the role of non-alcoholic fatty liver disease (NAFLD) in the progression from prehypertension to hypertension. This study was conducted to investigate the association of NAFLD and its severity with the risk of hypertension developing from prehypertension. METHODS: The study cohort comprised 25,433 participants from the Kailuan study with prehypertension at baseline; those with excessive alcohol consumption and other liver diseases were excluded. NAFLD was diagnosed by ultrasonography and stratified as mild, moderate, or severe. Univariable and multivariable Cox proportional hazard regression was used to calculate the hazard ratios (HRs) and 95% confidence intervals (CIs) of incident hypertension according to the presence and 3 categories of severity of NAFLD. RESULTS: During a median of 12.6 years of follow-up, 10,638 participants progressed to hypertension from prehypertension. After adjusting for multiple risk factors, patients with prehypertension and NAFLD had a 15% higher risk of incident hypertension than those without NAFLD (HR = 1.15, 95% CI 1.10-1.21). Moreover, the severity of NAFLD was associated with the incidence of hypertension, which was higher in patients with more severe NAFLD (HR = 1.15 [95% CI 1.10-1.21] in the mild NAFLD group; HR = 1.15 [95% CI 1.07-1.24] in the moderate NAFLD group; and HR = 1.20 [95% CI 1.03-1.41] in the severe NAFLD group). Subgroup analysis indicated that age and baseline systolic blood pressure may modify this association. CONCLUSIONS NAFLD is an independent risk factor for hypertension in patients with prehypertension. The risk of incident hypertension increases with the severity of NAFLD.

An effective therapeutic regimen for hepatic fibrosis requires a deep understanding of the pathogenesis mechanism. Hepatic fibrosis is characterized by activated hepatic stellate cells (aHSCs) with an excessive production of extracellular matrix. Although promoted activation of HSCs by M2 macrophages has been demonstrated, the molecular mechanism involved remains ambiguous. Herein, we propose that the vitamin D receptor (VDR) involved in macrophage polarization may regulate the communication between macrophages and HSCs by changing the functions of exosomes. We confirm that activating the VDR can inhibit the effect of M2 macrophages on HSC activation. The exosomes derived from M2 macrophages can promote HSC activation, while stimulating VDR alters the protein profiles and reverses their roles in M2 macrophage exosomes. Smooth muscle cell-associated protein 5 (SMAP-5) was found to be the key effector protein in promoting HSC activation by regulating autophagy flux. Building on these results, we show that a combined treatment of a VDR agonist and a macrophage-targeted exosomal secretion inhibitor achieves an excellent anti-hepatic fibrosis effect. In this study, we aim to elucidate the association between VDR and macrophages in HSC activation. The results contribute to our understanding of the pathogenesis mechanism of hepatic fibrosis, and provide potential therapeutic targets for its treatment.
