OBJECTIVETo investigate the effects of simvastatin on the proliferation and apoptosis of prostatic epithelial RWPE-1 cells.

METHODSRWPE-1 cells cultured in vitro were treated with simvastatin at 0, 10, 20, and 40 μmol/L for 24, 48, and 72 hours followed by determination of their proliferation by MTT assay, and their apoptosis by flow cytometry. The mRNA and protein expressions of Bcl-2, Bax, and Cx43 were detected by fluorescence quantitative RT-PCR and Western blot, respectively.

RESULTSAfter 72 hours of treatment with simvastatin at 10, 20, and 40 μmol/L, the inhibition rates of the RWPE-1 cells were (21.07 ± 6.41)%, (34.87 ± 9.65)%, and (47.18 ± 10.88)%, respectively, significantly higher than (1.21 ± 0.54)% in the control group (P < 0.05) and in a dose-dependent manner (P < 0.05); the cell apoptosis rates were (0.066 ± 0.016)%, (0.126 ± 0.023)%, and (0.192 ± 0.025)%, respectively, remarkably higher than (0.015 ± 0.005)% in the control (P < 0.05) and also in a dose-dependent manner (P < 0.05); the mRNA and protein expressions of Bcl-2 were decreasing while those of Bax and Cx43 increasing with the increased concentration of simvastatin (P < 0.05). The expression of Cx43 was correlated negatively with that of Bcl-2 but positively with that of Bax.

CONCLUSIONSimvastatin inhibits the proliferation of prostate epithelial cells and induce their apoptosis by acting on the gap junctional intercellular communication.

OBJECTIVETo determine whether oral statins can delay the progression of benign prostatic hyperplasia (BPH) and lower urinary tract symptoms (LUTS).

METHODSWe conducted a retrospective cohort study of 50-69-year-old males who came for physical examination in our hospital between January 2003 and December 2008. We designed the inclusion criteria, followed them up for 5 years, and investigated the relationship of oral statins with the clinical progression of BPH and LUTS.

RESULTSTotally, 653 men met the inclusion criteria and were included in this study, of whom 283 were treated with oral statins (group 1) while the other 370 with none (group 2). There were no statistically significant differences between the two groups in age and baseline IPSS, Qmax, and prostate volume (PV) (P > 0.05). During the follow-up, 24 cases in group 1 and 35 cases in group 2 were excluded for obvious dys-uria. A gradual increase was observed in IPSS in both groups 1 and 2 year by year from the baseline to the 5th year of follow-up, but significantly lower in the former group (4.27 +/- 1.16, 4.63 +/- 1.05, 5.27 +/- 0.96, 6.41 +/- 1.04, 7.21 +/- 1.21, and 7.93 +/-1.50) than in the latter (4.24 +/- 1.35, 5.26 +/- 1.23, 6.84 +/- 1.20, 8.75 +/- 1.84, 10.82 +/- 3.01, and 12.98 +/- 4.21) (P < 0.01); a gradual decrease was seen in Qmax, though markedly higher in group 1 ([26.56 +/- 2.09], [24.06 +/- 1.94], [21.33 +/- 1.66], [19.24 +/- 1.54], [17.44 +/- 1.53], and [16.27 +/- 1.37] ml/s) than in group 2 ([26.74 +/- 2.40], [23.62 +/- 2.01], [20.63 +/- 1.69], [17.72 +/- 1.48], [14.82 +/- 1.11], and [11.86 +/- 1.24] ml/s) (P < 0.01); and a gradual increase was found in PV, but remarkably smaller in the former group ([19.82 +/- 4.94], [22.60 +/- 4.99], [25.80 +/- 5.20], [27.92 +/- 5.05], [29.11 +/- 5.24], and [29.97 +/- 5.26] ml) than in the latter ([20.21 +/- 4.78], [24.30 +/- 4.98], [28.50 +/- 5.14], [32.84 +/- 4.77], [36.99 +/- 4.78], and [40.90 +/- 4.78] ml) (P < 0.01). Longer medication of statins was associated with better efficacy.

CONCLUSIONOral statins can significantly delay the clinical progression of BPH and LUTS.

OBJECTIVETo explore the efficacy of Qishen Huoxue Granules (QHG) for auxiliary treatment of critical patients with acute kidney injury (AKI).

METHODSFifty-two AKI patients came from critical care medical department of Beijing Friendship Hospital were randomly assigned to two groups: Group A (25 patients) was treated with QHG (consisted of Radix Astragali, Radix Salviae miltiorrhizae, Radix Paeoniae rubra, Flos Carthami, and Radix Angelicae sinensis, etc., 10 g/bag, administered via gastric perfusion, 3 times per day, 10 g in each time) and continuous renal replacement therapy (CRRT); Group B (27 cases) was treated only by CRRT, all for 14 days. Besides, mechanical ventilation and vasoactive drugs were applied in case of necessary. The time of renal function recovery, days in ICU, 28-day mortality, changes of serum Cystatin C concentration as well as the time of mechanical ventilation (T-V) and vasoactive drugs application (T-D) in patients, who received corresponding treatment were observed.

RESULTSThe renal function recovery time in Group A was markedly earlier than that in Group B (P < 0.05), with concentration of serum Cystatin C began to decrease from day 10. T-V and T-D in Group A were markedly shorter than those in Group B, respectively (P < 0.05). No significantly statistical difference between the two groups for days in ICU and 28-day mortality was found (P > 0.05).

CONCLUSIONQHG shows favorable prospect in treating critical AKI patients, it can significantly accelerate the renal function recovery time, shorten the duration of mechanical ventilation and vasoactive drugs application.

Activation of acid-sensing ion channels (ASICs) plays an important role in neuroinflammation.Macrophage recruitment to the sites of inflammation is an essential step in host defense.ASIC 1 and ASIC3 have been reported to mediate the endocytosis and maturation of bone marrow derived macrophages.However,the expression and inflammation-related functions of ASICs in RAW 264.7 cells,another common macrophage,are still elusive.In the present study,we first demonstrated the presence of ASIC 1,ASIC2a and ASIC3 in RAW 264.7 macrophage cell line by using reverse transcriptase polymerase chain reaction (RT-PCR),Western blotting and immunofluorescence experiments.The non-specific ASICs inhibitor amiloride and specific homomeric ASIC 1 a blocker PcTx 1 reduced the production of iNOS and COX-2 by LPS-induced activating RAW 264.7 cells.Furthermore,not only amiloride but also PcTx 1 inhibited the migration and LPS-induced apoptosis of RAW 264.7 cells.Taken together,our findings suggest that ASICs promote the inflammatory response and apoptosis of RAW 264.7 cells,and ASICs may serve as a potential novel target for immunological disease therapy.

OBJECTIVETo explore the clinicopathological features, immunophenotype, differential diagnosis, pathogenesis and prognosis of villous adenoma with poorly differentiated adenocarcinoma of the urinary tract.

METHODSClinical and pathologic findings of 3 cases of villous adenoma with poorly differentiated adenocarcinoma of the urinary tract were analyzed by gross examination, microscopic investigation and immunohistochemical staining. The related literatures were reviewed.

RESULTSAll of the three cases were middle-aged or elderly patients. Three cases all presented with hematuria and mucusuria. Endoscopic examination identified that case 1 had a polyp with broad attachment in the dome of bladder, case 2 had a solid mass in the ureter, and case 3 had a exophytic fungating tumor in the renal pelvis. Microscopically, case 1 revealed a papillary lesion with finger-like processes lined by pseudostratified columnar epithelium with abundant goblet cells. The cells demonstrated moderate degree dysplasia. In case 2 and case 3, both villous adenomas and poorly differentiated adenocarcinoma were observed, the adenoma cells arranged in a cribriform pattern, and the tumor cells showed severe atypia, mitotic activity, and transition with invasive poorly differentiated adenocarcinoma. Immunohistochemically, the tumor cells in three cases were positive for CK20, CEA,EMA and MUC-1; none of them expressed cdx-2 and PSA; In case 2 and 3, the same immunophenotype of villous adenomas and their associated adenocarcinomas was observed, but the number of the positive cells of p53 and Ki-67 staining were significantly increased in the area of adenocarcinomas than in that of the villous adenomas.

CONCLUSIONSVillous adenoma of the urinary tract is rare. It can occur in the urinary bladder, urachus, renal pelvis, ureter and urethra. These lesions may have malignant potential and frequently coexist with other malignant tumors. So, villous adenoma of the urinary tract should be removed completely and sampled thoroughly to avoid missing a more aggressive component.

OBJECTIVETo explore the characteristics of B cell-activating factor (BAFF) secreted by peripheral blood monocyte-derived dendritic cell (MoDC) in chronic idiopathic thrombocytopenic purpura (cITP) and the function of MoDC on B cell proliferation.

METHODSTen cITP patients were studied dynamically before and after treatment. The BAFF levels in serum and the supernatant of LPS stimulated MoDC were tested with ELISA. The BAFF gene expression in LPS stimulated MoDC was tested with RQ-PCR, the B cell proliferation co-cultured with the supernatant of LPS stimulated MoDC for 5 days was tested with flow cytometry for CFSE and (3)H thymidine incorporation.

RESULTSThe BAFF level in serum (serum BAFF) \[(2461 ± 483) ng/L\], and supernatant of LPS stimulated MoDC (supernatant BAFF) \[(1113 ± 113) ng/L\] and BAFF mRNA in LPS stimulated MoDC (BAFF mRNA) (1.70 ± 0.23) before treatment were higher than that after treatment \[(621 ± 53) ng/L, (490 ± 49) ng/L and 0.37 ± 0.12\] and normal group \[(742 ± 77) ng/L, (582 ± 63) ng/L and 0.52 ± 0.08\]. There was a positive correlation among serum BAFF, supernatant BAFF and BAFF mRNA, and a negative correlation among serum BAFF, supernatant BAFF and BAFF mRNA and blood platelet count (BPC) in all ITP patients. The supernatant of LPS-stimulated MoDC from untreated patients enhanced B cell proliferation as compared with the supernatant of LPS-stimulated MoDC from treated patients and normal group.

CONCLUSIONBAFF might contribute to disease development in cITP. MoDC may directly increase B cell proliferation by secreting BAFF without T cell help, playing an important role in the antibody production in cITP.

OBJECTIVETo study the therapeutic effect of combined therapy with Chinese drugs and immuno-suppressors, mainly anti-lymphocyte globulin/anti-thymus globulin (ALG/ATG), for the treatment of severe aplastic anemia (SAA), the efficacy associated factors and adverse effects as well.

METHODSA retrospective analysis was conducted on 65 patients with SAA treated by combined therapy which was supplemented with cyclosporin A, androgen, hematopoietic growth factor, etc.

RESULTSOf the 57 patients followed-up, 26 (45.6%) were basically cured, 15 (26.3%) remitted, and 8 (14.0%) improved markedly, the total effective rate being 85.9%. By separately comparing with a single item of clinical data, it was shown that the therapeutic effectiveness was correlated, to a certain extent, with age, illness duration, neutrophil count, and bone marrow proliferation in patients before treatment, as well as with infection that occurred in the follow-up period. It was obviously higher in patients with peripheral neutrophil count > 0.5 x 10 10(9)/L (P<0.05). Various degrees of serum sickness-like reactions occurred in the treatment of 36 patients, including fever in 36 (63.2%), skin rash in 8 (14.0%), and musculoskeletal pain in 5 (8.8%).

CONCLUSIONSThe therapeutic effect of combined therapy with Chinese drugs and ALG/ATG in treating SAA could be affirmed, showing some superiority as compared with Western medicine alone. The patients' age, duration of illness, neutrophil count, and bone marrow proliferation before treatment, and degree of infection that occurred could affect the therapeutic efficacy to a certain extent. Adverse reactions resulting from the combined therapy are less, showing the toxicity reducing and effect enhancing action of Chinese drugs.

OBJECTIVETo investigate the correlation between different Chinese medicine (CM) syndromes and variations in microcirculation in septic shock patients.

METHODSseventy Septic shock patients were divided into four groups: heat damaging qi-yin group (HDQY, 23 cases); yin exhaustion and yang collapse group (YEYC, 26 cases); excessive heat in Fu organ group (EHFO, 10 cases); and heat damaging nutrient-blood group (HDNB, 11 cases). Sublingual microcirculation parameters were observed by sidestream dark-field (SDF) imaging and scored by Acute Physiology and Chronic Health Evaluation II (APACHE II) and the Sequential Organ Failure Assessment (SOFA), and parameters of microcirculation perfusion variations and prognoses were analyzed.

RESULTSCompared with those with qi-yin heat damage, perfused vessel density (PVD) in other groups decreased dramatically (P<0.05), and APACHE II scores increased significantly (P<0.05). In addition, the recovery time was prolonged substantially (P<0.05), and the mixed venous oxygen saturation (SVO2) decreased (P<0.05). Blood lactic acid increased significantly (P<0.05), and the mixed SVO decreased (P<0.05), in the YEYC group. Compared with the thermal injury camp blood group, sublingual microcirculation parameter variations showed no obvious difference in the YEYC and EHFO groups (P>0.05). There were significant positive correlations between CM syndromes and APACHE II scoring in different groups (r=0.512, P<0.05). There were negative correlations between PVD and APACHE II scoring (r=-0.378, P=0.043), the proportion of perfused vessels (PPV) and APACHE II scoring (r=-0.472, P=0.008), as well as between the microvascular flow index (MFI) and APACHE II scoring (r=-0.424, P=0.023) in different patients.

CONCLUSIONSublingual microcirculation may serve as a clinical diagnostic parameter of the patient condition, as well as being a prognostic indicator.
