Late-onset hypogonadism (LOH) is a clinical and bio-chemical syndrome associated with advancing age in males and seriously affects the quality of life of some of the patients. A classical therapeutic option for LOH is testosterone supplementary treatment (TST). Its effectiveness has been verified, whereas its long-term safety remains to be further evaluated. With deeper insights into LOH, many new therapeutic strategies have been proposed, which include the treatments with gonadotropins, testosterone precursors (such as dehydroepiandrosterone [DHEA]), non-aromatizable androgens (such as dihydrotestosterone [DHT]), antiestrogens (such as aromatase inhibitors and estrogen receptor antagonists), and Chinese medicine. Meanwhile, studies on the transplantation of Leydig stem cells, selective androgen receptor modulators (SARMs), and selective estrogen receptor beta (ERbeta) agonists have shed new light on the treatment of LOH.

Hypertension is one of the high prevalence diseases in Xinjiang,which severely affect the body-mind heath of the people.In Northwest area,particularly in xinjiang,dryness syndrome is prevailed owing to environmental factor.Therefore,dryness syndrome of climacteric hypertension in xinjiang is more prevalent than that in other areas.Discussion on the effect of environmental factors on climacteric hypertension is a main aspect of Northwest dryness syndrome study.It may provide reliable and helpful basis of prevention and treatment of climacteric hypertension in xinjiang.

Objective To observe the therapeutic effect of Jingganquzhi decoction(JQ,净肝祛脂汤) in treating non-alcoholic fatty liver.Methods Eighty patients with non-alcoholic fatty liver were randomly divided into treatment group to receive JQ and control group to receive Dongbaogantai(DG,东宝肝泰) orally for 3 months.The changes of liver function,blood lipids,B ultrasonic examination were observed.Results After the treatment,the liver function criteria: alanine aminotransferase(ALT),aspartate aminotransferase(AST),alkaline phosphatase(ALP),?-glutamyltransferase(?-GGT) and blood lipids of triglycerides(TG),total cholesterol(TC) were lower than those before the treatment,while the high-density lipoprotein cholesterol(HDL-C) was higher than that before the treatment in both groups(all P

The Haemophilus influenzae (Hi) is a common opportunistic pathogen from human respiratory tract. The lower immunity can cause the disease. After the biofilm (BF) is formatted by Hi at the site of infection, the antibiotic sensitivity is declined, which often causes the chronic disease, inducing the difficulty in clinical treatment. In recent years, the pathogenic?ity of Hi BF and BF form related factors have gradually become the focus of clinical and basic research. This paper reviewed recent studies as following.

To explore the anti-atherosclerotic mechanism of estrogen and especially observe the effect of estradiol on the content of cholesterol in J774a.1 mouse mononuclear/macrophage-derived foam cells which were incubated with oxidized low-density lipoproteins (ox-LDL). J774a.1 mouse mononuclear/macrophages were incubated with ox-LDL or with both ox-LDL and estradiol (1, 0.1 or 0.01 micromol x L(-1)). Oil red O staining was used to observe the formation of foam cells, and cholesterol oxidase fluorometric was used to determine the content of cellular cholesterol content. Western blotting and RTFQ-PCR were used to observe the expressions of scavenger receptor class B type I (SR-B I ) in J774a.1 foam cells. Compared with the control cells, J774a.1 mouse mononuclear/macrophage-derived foam cells showed significantly increased contents of total cholesterol and cholesterol ester (P < 0.001) and decreased SR-B I mRNA expression (P < 0.01). Estradiol treatment significantly lowered the contents of total cholesterol and cholesterol ester (P < 0.05), and increased SR-B I protein and mRNA expression (P < 0.01) in the foam cells in a dose-dependent manner. Estradiol can inhibit the formation of mononuclear/macrophage-derived foam cells by decreasing the contents of total cholesterol and cholesterol ester and up-regulating the expression of SR-B I in the foam cells.

ObjectiveTo determine the current students' social anxiety status and maternal factors in school students( grade 5-7) in Harbin,and provided scientific guidance relevant to students'social anxiety.Methods 1526 mother-child pairs collected by random cluster sampling,children completed the social anxiety scale for children (SASC),security scale,coping strategies questionnaire( consist of ambivalence and avoidance subscale),acceptance scale and psychological control scale,and mothers completed the center for epidemiologic studies depression inventory (CES-D),self-rating anxiety scale (SAS).ResultsThe total positive detection rate of social anxiety was 13.6％,there was no significantly difference between boys and girls (P ＞ 0.05) ; the positive detection rate of Grade 6 was higher than Grade 5 and Grade 7.There were positive correlation between social anxiety and mother's psychological control,mother's depression,mother's anxiety ( r =0.228,0.143,0.122) ; negative correlation with mother's acceptance( r =-0.214).Linear regression indicated that only three variables (mother's psychological control,mother's acceptance,mother's depression) were at the P ＜ 0.05 level.The regression coefficients for the three variables were 1.557,- 1.092 and 0.040,respectively.ConclusionMaternal highly psychological control,lowly acceptance and maternal anxiety depression all play a role in promoting the occurrence of students' social anxiety.

ObjectiveTo analyze the internet-based cognitive behavior therapy (ICBT) intervent medical university students' social anxiety,and provide experiences and theoretical basis for future social anxiety interventions.Methods45 medical students of social anxiety were voluntarily divided into the one-to-one intervention group,one-to-five intervention group and control group.The control group did not intervene,one-to-one intervention group and one-to-five intervention group were interfered single person or team by cognitive behavioral therapy,respectively.The level and symptom of social anxiety of the 3 groups were assessed before and after the intervention by social phobia inventory(SPIN) and Social anxiety symptoms interview inventory.ResultsAfter the intervention,the scores of SPIN and the 3 subscales within it (fear,avoidance and physiological) of one-to-one ICBT group and one-to-five ICBT group were lower than those of the control group (SPIN scores:one-to-one ICBT group 15.60 ±7.87,one-to-five ICBT group 14.87 ± 8.83,control group 20.20 ± 11.46).Variance analysis showed that,in addition to physiological subscale(F =0.641,P ＞ 0.05 ),the scores of SPIN,fear and avoidance subscales had significant differences among the3 groups (F=3.764,P=0.018; F=3.606,P=0.021 ; F=5.444,P=0.005).In the analysis of participants'social anxiety symptoms,after treatment,in one-to-one ICBT group,there was 1 participant changed into subthreshold social anxiety and 1 participant into normal in the 2 threshold social anxiety participants.All the 3 subthreshold social anxiety participants changed into normal.In one-to-five ICBT group,there was 1 threshold social anxiety participant lapsed to subthreshold social anxiety,1 subthreshold social anxiety participants still remained in subthreshold social anxiety,2 symptomatic social anxiety participants changed into normal.But there were no significant changes in control group.ConclusionsAll the two methods of intervention have a certain effect.The effect of one-to-one intervention therapy is most significant.
