AIM: To investigate the influence of Astragalus Injection on morphology,cell cycle and oxidative stress of rat's glomerular mesangial cells(GMC) cultured with advanced glycation end products(AGEs). METHODS: GMC were incubated in culture medium containing AGEs in the presence of Astragalus Injection and aminoguanidin for 48 h.At the same time,the normal and control groups were established.Then the cultured GMC was stained by mixed fluorescence liquid and observed under fluorescence microscope.Cell cycle of GMC was analyzed using flowcytometry.The activity of SOD、MDA and GSH-PX in GMC supernatant were measured by test kit.The level of ROS was detected by flowcytometry. RESULTS: Morphology analysis showed that the morphology and structure of normal GMC were normal.The structure of most cells in AGEs was unclear,cell counts increased markedly and they grew intensively.Cell cycle analysis showed that cell percentage of S phase increased and G_0/G_1 reduced.The level of ROS,MDA remarkably increased,and SOD,GSHPX activity reduced.Whereas Astragalus Injection was added,cell morphology tended to be basically normal and cell counts decreased,the percentage of S phase also decreased.The level of ROS,MDA and the SOD,GSH-PX activity restored in comparison with the control groups. CONCLUSION: Astragalus Injection can prevent GMC from lesion caused by AGEs.Astragalus Injection may protect GMC from retarding the progression of diabetic nepropathy by partially inhibiting the occurrence of oxidative stress.

Objective To explore the cause,treatment and prognosis of delayed massive haemorrhage (DMH) after pancreatic resection.Method Clinical data of 1554 patients undergoing pancreatectomy in our hospital from Aug 2003 to Aug 2013 were retrospectively analyzed.Results 16 patients suffered from DMH,including 13 patients who had undergone pancreaticoduodenectomy,and 3 patients who had had resection of pancreatic body and tail.Gastrointestinal haemorrhage occurred in 6 patients,intra-abdominal haemorrhage occurred in 10 patients,respectively.Reoperations were performed in 11 patients,transcatheter arterial embolization (TAE) undertaken in 2 patients,and endoscopic treatment in 3 patients.10 patients recovered after treatment,6 patients (6/16) died.Conclusions The mortality of DMH after pancreatic surgery is high.Postoperative pancreatic leak and gastrointestinal stress ulcer are the most possible risk factors,intra-abdominal arterial haemorrhage is the main cause of death.

Objective To compare the clinical efficacy between continuous and intermittent androgen deprivation in high risk prostate cancer.Methods Sixty-four patients with high risk prostate cancer were treated from January 2008 to April 2009,36 cases who accepted goserelin and bicalutamide were taken as intermittent hormonal therapy (intermittent treatment group),while 28 cases who accepted bilateral orchiectomy in addition to flutamide were regarded as continuous hormonal therapy (continuous treatment group).The comparison of tumor specific mortality,time of prostate specific antigen (PSA) to nadir,tine to PSA recurrence,serum testerone and quality of life score were assessed between the two groups.Results In continuous treatment group and intermittent treatment group,follow-up period was (26.4 ± 10.3) and (28.1 ± 8.7) months,the time of PSA to nadir was (3.8 ± 2.1 ) and (4.0 ± 3.6) months,the time to PSA recurrence was (20.1 ± 12.3) and (24.5 ± 14.6) months,respectively.There was no significant difference between the two groups.At the time of 18,24 and 30 months after therapy,serum testerone was 0.85,0.88,0.89 μg/L in continuous treatment group,while 1.21,1.36,1.48 μg/L in intermittent treatment group,respectively (P ＜ 0.05 ).Similarly,quality of life score was 38.7,40.5,39.8 scores in continuous treatment group,while 49.2,51.4,52.3 scores in intermittent treatment group at the time of 12,18 and 30 months after therapy,respectively (P ＜ 0.05 ).Conclusions Clinical efficacy could not been found between continuous and intermittent endocrinic therapy of prostate cancer.During intermittent,quality of life seems to be better and increases in accordance with serum testerone recurrence at given time.

OBJECTIVETo explore the expression of tyrosine phosphatase containing C-src homology SH-2 (SHP-1 and SHP-2) in benign prostate hyperplasia.

METHODSWith En Vision two-step method, the expression of SHP-1 and SHP-2 was detected in 10 cases of normal prostate tissue, 30 cases of BPH, 20 cases of PIN, 20 cases of high differential Pca and 20 cases of low differential Pca.

RESULTThe expression of SHP-2 in normal group was mainly distributed in the cytoplasm of secretive cells and basal cells, and a little part in the nucleu. In BPH it was distributed equally in the plasm and nucleu. In PIN, high differential Pca and low differential Pca, SHP-2 expressed mainly in nucleu. The average dyeing index of SHP-2 in each group is 0.4, 1.7, 2.1, 2.2 and 2.6. SHP-1 positive expression in normal prostate, BPH, PIN and high differential Pca showed differentiating layer staining in the cytoplasm of secretive cells and basal cells, while not in low differential Pca. The average dyeing index of SHP-1 in each group is 1.8, 1.8, 1.5, 1.2 and 0.4.

CONCLUSIONThere are transformation in signal transduction relation with SHP-1 and SHP-2 in the progress of prostate cell proliferation, differentiation and malignant. The abnormal activation and distribution of SHP-2 might induce prostate reconstruction and hyperplasia, even carcinoma.

OBJECTIVETo observe the effect of Jianpi Yangzheng Xiaozheng Recipe (JYXR) on the tumor inhibition rate of subcutaneous transplanted tumor gastric cancer cell line MGC-803 in BALB/c nude mice, and to study its molecular mechanism of apoptosis and autophagy.

METHODSGastric cancer cell line MGC-803 was subcutaneously inoculated to nude mice for preparing transplanted gastric cancer models. Totally 32 BALB/c nude mice were randomly divided into 4 groups according to random digit table, i.e., the negative control group, the positive control group, the high dose JYXR group, the low dose JYXR group, 8 in each group. Normal saline was administered to mice in the negative control group by gastrogavage. 5-fluorouracil (5-Fu) at 2. 5 mg/kg was administered to mice in the positive control group by gastrogavage. JYXR at 85 and 43 g/kg was administered to mice in the high dose JYXR group and the low dose JYXR group by gastrogavage, once per day for 10 successive days. The effect of JYXR on the tumor inhibition rate of subcutaneous transplanted tumor was observed. Effects of JYXR on gene expression levels of Bax, Bcl-2, Fas, Cyclin D1, Cyclin D2, and Cyclin D3 in transplanted tumor were observed by real-time PCR. Effects of JYXR on protein expression levels of Procaspase-3, Procaspase-8, Procaspase-9, cleaved-PARP, Beclin-1, and LC3B were detected using Western blot.

RESULTS(1) Compared with the negative control group, the tumor weight was obviously reduced in the rest three groups (P <0. 05). The tumor weight was higher in the high dose JYXR group and the low dose JYXR group than in the positive control group (P <0. 05). (2) Results of RT-PCR indicated that, compared with the negative control group, expression levels of Bax were up-regulated, but expression levels of Bcl-2, Cyclin D1, Cyclin D2, and Cyclin D3 were down-regulated in the positive control group and JYXR groups (P <0. 05). The expression level of Fas was up-regulated in the positive control group and the high dose JYXR group (P <0. 05). Compared with the positive control group, expression levels of Fas, and Bax were all down-regulated, but expression levels of Bcl-2, Cyclin D2, and Cyclin D3 were all up-regulated in the high dose JYXR group and the low dose JYXR group (all P <0. 05). The expression level of Cyclin D1 was down-regulated in the high dose JYXR group, but it was up-regulated in the low dose JYXR group ( both P <0. 05). (3) Results of Western blot showed, compared with the negative control group, expression levels of Procaspase-3, Procaspase-8, and Procaspase-9 were down-regulated, but expression levels of cleaved-PARP, Beclin-1, and LC3B II were up-regulated in the high dose JYXR group and the low dose JYXR group (all P <0.05). Compared with the negative control group, expression levels of Procaspase-3, Procaspase-8, Procaspase-9, and LC3B II were down-regulated, but expression levels of cleaved-PARP, Beclin-1, and LC3B I were up-regulated in the positive control group (all P <0. 05).

CONCLUSIONSJYXR showed significant inhibition on subcutaneous transplanted tumor gastric cancer cell line MGC-803 in BALB/c nude mice. Its mechanism might be associated with activating apoptosis and autophagy correlated factors.
