OBJECTIVETo analyze the effects of Ling Qi Juan Gan capsule drug-containing serum at different concentrations on the platelet-derived growth factor (PDGF)-induced proliferative capabilities of and JAK2 and p-STAT3 protein expression in hepatic stellate cells (HSC) using an in vitro system.

METHODSTwenty-five Sprague-Dawley rats were randomly divided into five equal groups for intragastric administration of physiological saline (10 ml/kg; group A), Fufang Biejia Ruangan tablet solution (1.5 g/kg; group B), or Ling Qi Juan Gan capsule solution at low dose (2.125 g/kg; group C1), mid dose (4.25 g/kg; group C2), or high dose (8.5 g/kg; group C3). The post-administration serum isolated from each rat (200 ml/L) was used to treat the HSC-T6 cell line following induction by PDGF (10 ng/ml). At 24, 48 and 72 h post-exposure, the cells' proliferation was measured using the Cell Counting Kit-8 (CCK-8) colorimetric assay. In addition, at 24 h post-exposure the expression of JAK2 and p-STAT3 was measured by western blotting (expressed as grey scale intensity). Multiple group comparison of repeated measures data was made by one-way ANOVA with Student-Newman-Keuls post hoc test.

RESULTSCompared to group A, groups C2 and C3 had significantly higher inhibited proliferation at all post-exposure time points examined (24 h: A = 1.550 +/- 0.065, C2 = 1.335 +/- 0.106, C3 = 1.241 +/- 0.205; 48 h: A = 1.311 +/- 0.650, C2 = 1.090 +/- 0.106, C3 = 0.909 +/- 0.191; 72 h: A = 1.039 +/- 0.103, C2 = 0.719 +/- 0.116, C3 = 0.641 +/- 0.110, F = 36.292, all P less than 0.05); in contrast, compared to group A, group C1 showed no inhibition of proliferation at 24 h (1.522 +/- 0.128, P = 0.717) but showed significantly higher inhibition of proliferation at 48 h and 72 h (1.153 +/- 0.183 and 0.753 +/- 0.210, respectively, F = 36.292, P less than 0.05). Compared with group A, all Ling Qi Juan Gan capsule-containing serum-treated groups showed significantly lower expression of both JAK2 (A = 1.605 +/- 0.024 vs. C1 = 1.170 +/- 0.042, C2 = 0.842 +/- 0.036, C3 = 0.555 +/- 0.036, F = 43.091) and p-STAT3 (A = 1.401 +/- 0.030 vs. C1 = 1.229 +/- 0.025, C2 = 0.668 +/- 0.034, C3 = 0.630 +/- 0.026, F = 78.426, all P less than 0.01).

CONCLUSIONLing Qi Juan Gan capsule drug-containing serum can inhibit the proliferation of HSC-T6 cells in a dose-dependent manner and cause an overall decrease in the expression of JAK2 and p-STAT3 in activated HSC, thereby leading to a suppression of the JAK/STAT signal transduction pathway.

OBJECTIVETo explore the method and effect of inter-locking intramedullary nail and tripus in closed reduction for treating tibial fracture.

METHODSOne hundred and twenty-six patients of tibial fractures were treated by inter-locking intramedullary nail and tripus in closed reduction. There were 76 males and 50 females aged from 25 to 68, the mean age was 38; There were 86 close fractures and 40 open fractures (Gustilo I and II type). AO classification system was used for all cases, fracture type A in 49 cases, type B in 41 cases, type C in 36 cases.

RESULTSAll patients were followed up for 10 to 16 months. Fratures were cured, according to the criteria of Johner-Wruhs, the results were excellent in 103 cases, good in 18 cases, fair in 5 cases.

CONCLUSIONInter-locking intramedullary nail is the optimal operation method in treating tibial fracture. Static locking should be a routine way, and closed reduction, no stripping periosteum, infectious rate and complications are reduced. Through tripus work intensity are reduced and reduction easily during operation.

Objective To analyze the clinical and imaging features of a family(3 patients)with familial hemangioblastoma,and their diagnosis and prognosis.Methods The detailed data about clinical and imaging features of all patients diagnosed as familial hemangioblastoma,admitted to our hospital from October 2004 to May 2010,were analyzed,and the lesions of other regions,besides the tumor lesion,were observed.Results No lesions of other regions were noted in these 3 patients.Cranial MRI showed that 2 had cystic and solid tumor and 1 had solid tumor;,total removal was performed on these patients under microscope; regular follow-up was given and no recurrence was noted.Conclusion Familiar hemangioblastoma is serious hereditary disease; and MRI is the most important detective method; microsurgical operation is the most important therapy.Early diagnosis and treatment should be given to the patients with familiar hemangioblastoma due to its high recunence rate,having difficulty in operation and its trend to combining with other lesions of the other parts.

OBJECTIVETo observe the clinical effect of low-dose testosterone undecanoate capsules combined with tadalafil on late-onset hypogonadism (LOH) accompanied with ED.

METHODSNinety cases of LOH accompanied with ED who met the inclusion criteria were randomly divided into a control group and a combination therapy group, the former treated with tadalafil and the latter with low-dose testosterone undecanoate capsules combined with tadalafil. The LOH symptoms, IIEF-5 scores, sexual encounter profile (SEP) scores, prostate volumes, and the levels of total testosterone (TT), free testosterone (FT) and prostatic specific antigen (PSA) were recorded and compared between the two groups before and after treatment.

RESULTSThe IIEF-5 and SEP scores and the TT and FT levels were 20.6 +/- 3.8, 4.02 +/- 1.08, (15.4 +/- 3.4) nmol/L and (0.391 +/- 0.062) nmol/L, respectively, in the combination therapy group after treatment, significantly higher both than 15.7 +/- 3.9, 1.49 +/- 0.82, (10.1 +/- 1.2) nmol/L and (0.200 +/- 0.045) nmol/L before treatment (P < 0.01) and than 8.6 +/- 3.6, 3.50 +/- 1.21, (10.2 +/- 1.2) nmol/L and (0.210 +/- 0.051) nmol/L in the control group after treatment (P < 0.01).

CONCLUSIONLow-dose testosterone undecanoate capsules combined with tadalafil has a definite clinical effect and no obvious adverse reactions in the treatment of LOH accompanied with ED.

OBJECTIVETo investigate the effect of low-dose daily de-escalatory administration of tadalafil on psychological erectile dysfunction (ED).

METHODSWe randomized 84 psychological ED patients into an observation and a control group of equal number to receive low-dose daily de-escalatory administration and on-demand medication of tadalafil, respectively, both for 2 months. We compared the scores on IIEF-5 and erection hardness (EHS) between the two groups before and after the treatment.

RESULTSThe treatment and follow-up were accomplished for 79 cases, with 5 withdrawals in the control group. The IIEF-5 and EHS scores were remarkably improved in both the observation and control groups after treatment. The rate of therapeutic effectiveness was significantly higher in the observation group than in the control (95.2% vs 86.5%, P < 0.05).

CONCLUSIONLow-dose daily de-escalatory administration of tadalafil is highly effective and even better than on-demand medication of tadalafil for psychological ED.
