Contents of magnolol and honokiol in Magnolia officinalis Rehd. et Wils. and its processed products,yellow-fried, burn -fried and ginger-fried M. officinalis Rehd. et Wils. as well as commercially available M.officinalis Rehd. et Wils. and its processed products were assayed by TLC Scanning. Results showed that contents of the two constituents decreased after M. officinalis Rehd. et Wils. was processed. Among them the burn-fried product showed a most pronounce decrease of 30%, while both yellow-fried and ginger-fried products decreased about 20%. The contents of magnolol and honokiol in commercial M. officinalis Rehd. et Wils. and its ginger-fried product available in other provinces and cities differed greatly with some almost contain no magnolol and honokiol.

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 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.

Renal fibrosis is the final common pathway for all kinds of chronic kidney diseases to end-stage renal diseases. Angiotensin Ⅱ plays an important role in the process of renal fibrosis. 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.

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.

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.

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 prognostic factors in patients with sepsis and to provide the theoretical basis for clinical diagnosis and treatment. Methods A total of 141 septic patients were analyzed retrospectively. Patients were divided into two groups:those who were alive at time of ICU discharge ( survivors;n=83 ) and those who died or to give up before terminal stage ( nonsurvivors;n=58 ) . Then the clinical data were statistically ana-lyzed. Results In the death group: age, APACHE II score, blood urea nitrogen, serum creatinine, C-reactive protein were significantly higher than the survival group (P<0. 01) while albumin, pre albumin were lower than that in the survival group (P<0.01). The Logistic regression analysis illustrated: age ( > 60 years), APACHEIIscore ( >20 score) and blood urea nitrogen ( > 9 mmol/L) , serum creatinine ( > 176 μmol/L) , C-reactive protein level were independent predictors of death in patients with sepsis ( P<0 . 05 ) . Then drew the receiver oper-ating characteristic curve ( ROC curve) and analyzed the respective risk factor for predicting prognosis value of sep-sis with the help of ROC curve. Conclusion Age, high APACHE II score in early sepsis, increased urea nitro-gen, elevated serum creatinine and increased C-reactive protein levels were regarded as prognostic value indicators for adverse clinical outcomes in patients with sepsis.
