Besides 36 (28 single-tablets and 8 fixed-dose combinations) used antiretroviral drugs clinically, there are a number of investigational antiretroviral agents currently in phase 2-3 clinical trial. Tenofoviralafenamidefumarate (TAF) is a novel nucleoside analogue reverse transcriptase inhibitor that is potent and less toxicity than tenofovir (TDF). Doravirine is a non-nucleoside analogue reverse transcriptase inhibitor that demonstrates activity against NNRTI-resistant viral strains. GSK744 is an integrase inhibitor with a long acting preparation. In addition, several drugs with new mechanisms are also noted, for example, BMS-663 068 is a small molecule CD4 attachment inhibitors and cenicriviroc is a novel CCR5/CCR2 antagonist with antiretroviral activity and anti-inflammatory effects. Several drug classes that target known pathways in HIV latency have being developed, and leading the list are histone deacetylase inhibitors. Other agents include protein kinase C activators, positive transcription elongation factor activators, DNA methyl-transferase inhibitors and histone methyl-transferase inhibitors and so on. This review is focused on the above-mentioned drug candidates that may be used in clinical in next couple of years and those compounds that can reverse latent HIV infections.

Objective:This study aims to evaluate the effect of an elevated preoperative neutrophil to lymphocyte ratio (NLR) on outcome after comprehensive staging laparotomy or optimal tumor debulking surgery for epithelial ovarian cancer (EOC) and determine the value of the NLR as an independent prognostic prediction marker. Methods:A total of 80 women with primary EOC and with complete clinical and pathological information documented at the time of surgery were selected for this study. The optimum cut-off value of the preoperative NLR was identified through receiver operator characteristic (ROC) curve, and the patients were then classified into two groups: low and high NLR group. Univariate and multivariate analyses were performed to assess the prognostic effect of the preoperative NLR patients who underwent comprehensive staging laparotomy or optimal tumor debulking surgery. The levels of expression of CD68 were measured through immunohistochemistry. Results:The optimal cut-off value of the NLR was 3.8. The preoperative NLR differed significantly in the FIGO stage between the low NLR group (NLR ≤3.8) and the high NLR group (NLR>3.8), but no discrimination was observed in other parameters. The mean follow-up time was 45 months, and the post-operative 1-and 3-year survival rates were 93.7%and 60.0%, respectively. The preoperative NLR>3.8 and stageⅢ/Ⅳwere all risk factors for poor overall and disease-free survival. Multivariate analysis revealed the patients with high NLR (P<0.05) and stage Ⅲ/Ⅳ (P<0.05) had prognostic significance for poor overall survival. The number of CD68-positive tumor-associated macrophages was significantly higher in the high NLR group than in the low NLR group (54.65 ± 8.78 and 41.78 ± 9.10, respectively; P<0.001). Conclusion: An elevated blood preoperative NLR indicates poor prognosis in patients with EOC. Preoperative NLR may function as an important independent prognostic factor for patients with EOC.

Objective To develop a new instrument, the resilience scale for military personnel, and examine its reliability and validity. Methods The resilience scale for military personnel was compiled according to open-ended inventory survey . The sample consisted of 860 soldiers, 50 of them were re-tested with the new scale, another 80 tested by Chinese Military Mental Health Scale (CMMHS) at the same time. Factor analysis and Pearson's correlations were used to examine the reliability and validity of the resilience scale for military personnel. Results Based on factor analysis result, 5 factors were extracted, and added 1 lie factor, there were 32 items in theformal scale. The the Cronbach'α of total scale was 0.925, and subscales 0.597～0.810(P<0.01) , split-half reliability was 0.895 of total scale, and 0.384～0.739 of subscales (P < 0.01) ; retest reliability was 0.447 of total scale, and 0.494～0.658 of subscales(P<0.01 or P<0.05). The correlation was significant between the factors of this scale and factors of CMMHS. Conclusion The resilience scale for military personnel has good reliability and validity. The resilience scale has good psychological quality and proves to be applicable to Chinese military personnel in evaluating their resilience.

How to block angiotensin Ⅱ has been a focus of nephrology. This article reviewed the progress in traditional Chinese medicine against renal fibrosis with angiotensin Ⅱ as research target.

Objective To develop a mental resilience scale for military personnel and examine the reliability and validity of this scale.MethodsA total of 2611 male officers and soldiers chosen by random cluster sampling to outline the mental resilience scale for military personnel,with the subjects divided into group A and group B.In group A (n=1112) exploratory factor analysis and correlation analysis were used,and in group B (n=1499) confirmatory factor analysis was used.ResultsThe results of exploratory factor analysis and correlation analysis indicated that the Cronbach'? coefficient of total scale was 0.833,and that of subscales was 0.535-0.880;split-half reliability coefficient of total scale was 0.787,and that of subscales 0.339-0.611;retest-reliability coefficient of total scale was 0.401,and that of subscales 0.302-0.668.The correlation coefficients of total scale scores and each factor were 0.445-0.786 (P

Objective To investigate the protective effect of antihypertensive drug NO.1 on brain cortical tissue in spontaneously hypertensive rats.Methods A total of 60 spontaneously hypertensive rats (SHR,30 males and 30 females) and 12 healthy Wistar rats (6 males and 6 females) weighed (200 20) g,were randomly divided into 6 groups.Model group (SHR,n=12) and control group (healthy Wistar rats,n=12) were given the same dose of placebo.Captopril group (SHR,n=12) were given captopril 5 mg · kg-1 · d-1.The low-,median-and high-dose groups of antihypertensive drug NO.1 were given 0.25,0.5 and 1 g · kg 1 · d-1 respectively.After 4 weeks of treatment,carotid artery blood pressure was detected.All rats were sacrificed,and brain tissue samples were taken.The expressions of Bcl-2,Bax,necrosis factor NF-κB P65,chloride channel 2 and 3 (CLC-2 and CLC-3) were determined by RT-PCR and Western blotting.Results After 4 weeks of antihypertensive NO.1 treatment,SHR carotid artery blood pressure was (182.8 ± 7.3)mmHg in low dose group,(170.3±9.4) mmHg in medium dose group,and (163.9±10.6) mmHg in high dose group; and (205.4 ± 11.3)mmHg in the model group.Antihypertensive drug NO.1 significantly reduced blood pressure in spontaneously hypertensive rats,and had a concentrationresponse relationship (P＜0.05).Antihypertensive drug NO.1 decreased the expressions of Bax,CLC-2 and CLC-3,and increased the expressions of Bcl-2 and NF-κB P65.Conclusions Antihypertensive drug NO.1 plays a protective role in hypertension-induced cell injury by changing the metabolic enhancement in hypertension-induced cell volume decrease.

Objective To explore the mechanism of quercetin against the toxicity of amyloid β(Aβ)to neuroblastoma cell SK -N -SH.Methods In the experiment,SK -N -SH cells were divided to four groups,control group,Aβgroup,Aβ+quercetin group and quercetin group,and treated for 72h.The proliferation of cells,the concen-trations of reactive oxygen species (ROS)and glutathione (GSH)in cells were determined.Results Compared with the control group,Aβ[AβgrouP =(50.6 ±2.5)]could significantly suppress the proliferation of neuroblastoma cells (P =0.000).However,Aβgroup added with quercetin[Aβ+quercetin =(88.0 ±9.1)]showed decreased cellular toxicity induced by Aβ(P =0.001).Additionally,there was no significant difference between the control group and quercetin group.Likely,the concentration of ROS increased in Aβgroup (523.3 ±22.5 ),which was higher than (190.3 ±25.7)in the control group and (224.0 ±56.0)in quercetin group (P =0.000).At last,quercetin could increase GSH level in SK -N -SH cells and higher than Aβgroup[(3.0 ±0.2),P =0.004]and Aβ+quercetin [(5.6 ±1.1),P =0.008].Conclusion Quercetin could attenuate the suppression of proliferation of SK -N -SH cells induced by Aβ,that might be though increased concentration of GSH and decreased level of ROS.These data suggested that quercetin has clinical potentials in neurology.

Stress-related diseases are closely related to an abnormal cortisol secretion.Recent research implied that hair cortisol concentration which retrospectively records long-term cortisol basal level might possess superiority in the diagnosis of stresS-related diseases.This paper reviewed recent progresses in application of hair cortisol concentration in stress-related diseases (metabolic syndrome,obesity,cardiovascular disease,depression,PTSD,etc.) which showed abnormal long-term cortisol secretion in a wide range of situationS.This review proposed that the future research needs to take into accounts exclusion and/or balance of the influence factors,a longitudinal design in combination with acute-stress and chronic-stress biomarkers,and to develop new bio-markers related to hair cortisol concentration for study of stress related diseases,and establishment of standard protocols and clinical standards.
