Statins is first choice of hypercholesteroiemia. Recently, clinical investigations have shown that statins can correct blood pressure in hypertension patients accompanied with lipid abnormalities. This result can be observed not only in untreated patients but also in patients treated with antihypertensive drugs. But some researches did not support this result completely. To some extend, the mechanisms responsible for the hypotensive effect seem to be largely independent on the effect of statins on lipid profile, and may be related to the improvement of endothelial function and the regulation of angiotensin II receptors.

A new compound and five known compounds were isolated from the ethanolic extract of the leaves of Ilex pernyi Franch. Their structures were established on the basis of spectral analysis and identified as trans-isoeugenyl-α-L-arabinopynosyl(1→6)-β-D-glucopyranoside (1), kaempferol-3-O-sambubioside (2), quercetin-3-O-sambubioside (3), isoquercitrin (4), (+)-syringaresinol-O-β-D-glucopyranoside (5), amarantholidoside IV (6). Among them, compound 1 is a new phenolic glycoside, named as ilexperphenoside A, and compounds 2-6 were isolated from this plant for the first time.

Human parvovirus B19, generally referred to as B19 virus, has been closely associated with a variety of different autoimmune diseases due to the features of its capsid protein. B19 virus VP1 unique region protein that has sites of phospholipase A2 and several antigenic determinants is exposed on the outside of the viral capsid protein. As a result of that, B19 virus VP1 unique region protein can stimulate the host to produce autoantibodies, which induces and/or aggravates the autoimmune diseases. The biological characteristics of B19 virus VP1 unique region protein and its relationships with autoimmune diseases are de-scribed in this review based upon the published literatures and the work achieved by our research team. This review will be helpful to the prevention and treatment of B19 virus infection.

Objective To evaluate the role of miR219‐2‐3p in gastric cancer and the underlying mechanisms .Methods Real time RT‐PCR was employed to quantify the expression level of miR219‐2‐3p in matched tissues of 82 patients .In vitro cell proliferation , the expression of tumorgenesis related protein ERK1/2 was performed by overexpressing miR‐219‐2‐3p in gastric cancer cell line MGC803 .Results The expression level of miR‐219‐2‐3p significantly decreased in late stage gastric cancer (P< 0 .05) .The cell proliferation rate was significantly reduced in gastric cancer cell lines overexpressing miR‐219‐2‐3p .Furthermore ,the expression level of p‐ERK that activated form of ERK was significantly decreased whereas the total level of ERK was unchanged after overex‐pressing of miR‐219‐2‐3p in MGC803 cell lines .The expression level of p‐ERK was also increased in gastric cancer tissues .Conclu‐sion miR‐219‐2‐3p may acts as a tumor suppressor in gastric cancer by decreasing the activity of ERK 1/2 signaling pathway .

Objective To assess the feasibility and efficacy of robot-assisted laparoscopic simple prostatectomy (RALSP) for the treatment of benign prostatic hyperplasia (BPH) with large prostate.Methods From January 2014 to July 2015,16 patients with large prostate (≥80 ml) were treated by RALSP.The average patient's age was 69 years.The prostate volume was (98.3 ± 12.9) ml,preoperative residual urine was (78.0 ± 24.8) ml,the average IPSS was (22.9 ± 5.9),the average QOL was (4.8 ±1.5) and the average Qmax was (8.9 ± 3.7) ml/s,respectively.All patients agreed to accept RASP.The pre-operative and three months post-operative IPSS,QOL,residual urine and Qmax were compared and analyzed.Results All 16 patients underwent the surgeries uneventfully.The average operation time was (92.5 ± 15.5) minutes,the estimated blood loss was (125.5 ±25.5) ml,drainage time was (4.6 ±0.8)days,catheterization time was (7.9 ± 1.2) days and postoperative hospital stay was (5.1 ± 1.1) days.Three months after surgery,patient's IPSS was (11.8 ± 3.1),QOL was (1.6 ± 0.9),the average residual urine was (12.3 ± 2.6) ml and Qmax was (29.4 ± 11.6) ml/s,respectively.All the parameters significantly improved compared with the preoperative data (P ＜ 0.05).Conclusions Robot-assisted laparoscopic simple prostatectomy is a safe and effective method for the treatment of BPH patients with prostate volume larger than 80 ml.

Objective To analyze the correlation between CD4+ T cell count and HLA-DR or CD38 expression on peripheral CD8+ T cells in treatment-naive Chinese HIV/AIDS patients.Methods A total of 471 treatment-naive HIV-infected patients and 53 healthy volunteers were enrolled.HLA-DR or CD38 expression on peripheral CD8+ T cells, CD4+ T cell count, naive CD4+ T cell subsets and CD28 expression on T cells were measured by flow cytometry.Plasma HIV RNA load was quantified by real-time PCR (COBAS TaqMan RT-PCR).Mann-Whitney U test and Spearman's rank correlation test were used for statistical analysis.Results CD38 expression intensity on CD8+ T cells was negatively correlated with CD4+ T cell count (r =-0.53, P ＜ 0.001) and naive CD4+ T cell count (r =-0.48, P ＜ 0.001).CD38 expression on CD8+ T cells also displayed significantly negative correlation with CD28 expression on CD8+ T cells (r =-0.46, P ＜ 0.001).HLA-DR expression on CD8+ T cells did not show significant correlation with CD4+ T cell count.Only weak positive correlation was found between CD38 intensity on CD8+ T cells and plasma HIV RNA load.Conclusions Compared with HLA-DR, CD38 expression on CD8+ T cells shows more significant negative correlation with CD4+ T cell count in treatment-naive patients.CD38 and HLA-DR may play different roles on the persistent immune activation in HIV infection.
