[Objective] Examine the expression of Galectin-3 (Gal-3),B cell lymphoma-2 protein (Bcl-2) in epithelial ovarian cancer tissues with regard to clinicopathological and survival variables,testing whether they can serve as prognostic markers and provide evidence for further research.[Methods] 98 EOC tissues and 10 normal ovarian tissues were collected,as well as their clinical documents.The expression of Gal-3 and Bcl-2 was tested via immunohistochemical staining analysis.Then the correlation between these two proteins and the clinicopathological and survival variables of these patients were evaluated.[Results] Of the 98 EOC,Gal-3 and Bcl-2 were all cytoplasmic staining.Gal-3 was observed in a majority of the EOC tumor cell proper (75/98,76.5％) but not in normal ovarian tissues.Bcl-2 was observed in a majority of the EOC tumor cell proper (50/98,51.0％) but not in normal ovarian tissue.Spearman bivariate correlation test show that there was no correlation between the expression Gal-3 and Bcl-2 (P =0.867).Gal-3 expression in EOC was associated with histology and platinum sensitivity (P =0.043,P =0.038),while Bcl-2 was associated with FIGO stage (P =0.029).Cox univariate analysis revealed that Gal-3,Bcl-2 expression,platinum sensitivity,stage were associated with overall survival (P =0.008,P =0.021,P ＜ 0.001,P ＜ 0.001).Further multivariate analysis showed that only Gal-3 expression,platinum sensitivity,stage affected the survival of these patients (P =0.014,P =0.021,P ＜ 0.001).[Conclusions]The expression of Gal-3 and Bcl-2 in EOC was significantly higher than that in normal ovarian tissue,supposed that they may involve in the development and progression of EOC.Gal-3 expression was associated with histology,platinum sensitivity and survival,it may be an independent predictive factor for EOC prognosis.There was no correlation between the expression Gal-3 and Bcl-2 in EOC,the functional mechanism between these two protein need further research.

Objective To investigate the effect of Shenmai injection in treating elderly with orthostatic hypotension. Methods The total of 97 cases of patients with orthostatic hypotension were randomly divided into 2 groups, which was injected intravenously with 100 mL Shenmai injection once daily as the treatment group, with 100 mL glucose as the control.The treatment lasted 14 days. The clinical symptom score, the difference of blood pressure, the P￣selectin, and the platelet maximum aggregation were measured. Results Compared with the control, Shenmai injection significantly reduced the clinical symptom scores of patients (P<0.05), lowered the difference of blood pressure for upright and supine significantly (P<0.05), decreased the platelet maximum aggregation and P￣selectin remarkably (P<0.05). Conclusion Shenmai injection significantly reduces the difference of blood pressure for upright and supine of the elderly with orthostatic hypotension, and inhibits the activities of platelets, thus improves the clinical symptoms.

Objective To investigate the association between the systolic/diastolic orthostatic hypotension (OH-S/OH-D) and myoeardial infarction (MI) in the elderly.Methods Health screening physical examination were carried in 1081 subjects without MI aged over 65 years in Guangzhou Military region.The orthostatic blood pressure and heart rate were measured in supine position after resting for more than 5 minutes and at 0 and 2 minutes after standing.All the cases were divided into systolic or diastolic group on the basis of definition of orthostatic hypotension and followed up by telephone or inpatient medical records with mean period of 315.8 days.The primary endpoint was MI occurrence.Results The prevalence of OH in this cohort was 24.5％ ( OH-S/OH-D:19.3％/17.2％ ).Significant differences in the occurrence of OH and OH-S were found in the elderly and the very elderly subjects( ≥80 years) (26.1％ vs 20.1％,P=0.045; 21.0％ vs 14.6％,P =0.018),while no difference was found in OH-D.The prevalence of MI in the OH positive subjects was significantly higher than that in the OH negative subjects,as well as in OH-S or OH-D group.After adjustment of age,supine blood pressure,creatinine and cerebrovascular history by logistic regression,the association was observed between MI and OH ( HR 15.635,95 ％ CI 3.299-74.091,P=0.001),OH-S(HR 8.760,95％CI2.487-30.851,P=0.001)and OH-D(HR 3.889,95％ CI 1.097-13.790,P =0.035 ).Conclusion OH-S and OH-D hypotension are robust predictors for MI in the elderly.

Objective To review the survival outcomes in patients with endometrial stromal sarcoma(ESS)in Cancer Hospital，Peking Union Medical College，Chinese Academy of Medical Sciences，and to discuss prognostic factors and the role of post-operative adjuvant radiotherapy and chemotherapy.Methods Hospital records and pathology reports for 97 patients with ESS were reviewed.Among 97 patients，69 had low-grade ESS(LGESS)，16 had high-grade ESS(HGESS)and 12 had unclear grade.The median age at diagnosis was 44.0 years.The median follow-up time was 62 months(5-277 months).Atypical vaginal bleeding(43％)and prolonged and increased menses(36％)were the main symptoms.Results Totally 2-year and 5-year cumulative survival rates were 93％and 84％，respectively.Cumulative survival curves were significantly different between LGESS and HGESS，and so did cumulative survival curves between stage Ⅰ-Ⅱ and stage Ⅲ-Ⅳ(P＜0.05).Totally，34 patients(37％)had local or distant recurrence.The median time-to-recurrence(TTR)was 27 months.The recurrence rates of the patients with or without preserve of ovary were 89％and 24％，respectively(P=0.000).The local-control-rates of the patients who received or did not receive post-operative radiotherapy were 81％and 43％，respectively(P=0.011).Conclusions The prognosis of HGESS is obviously worse than that of LGESS.The risk of recurrence of patients with preserve of ovary was remarkably higher than that of patients without preserve of ovary.Postoperative radiotherapy could increase the local-control-rates.

Objective To study the effect of brucine on the growth of a hepatocellular carcinoma cell line in vitro. Methods Brucine was added into a liver cancer cell line of SMMC-7721 in vitro, at drug concentration of brucine from 2. 5 μg/ml to 400 μg/ml. The inhibition rate of cell growth was measured by MTT technique after the cells were cultured for 72 hours. The protein and mRNA expression of PCNA,cyclin D1 and FAS were respectively assayed with Western blotting and fluorescent quantitation RT-PCR techniques at 24, 48, 72 h. Results The inhibition rate of liver cancer cell was near 100% when the brucine concentration was at 320 μg/ml. The protein and mRNA expression of FAS were of no significant difference at 24 h vs 48 h ( seperately F = 2. 547,1. 582, all P ＞ 0. 05 ), and significant difference existed at 24 h vs 72 h( seperately F = 1. 036, 1. 137, all P ＜ 0. 05 ). The protein and mRNA expression of PCNA,Cyclin D1 were of no significant difference between various time period( seperately PCNA F = 3.612,2. 174,3.029;Cyclin D1 F=2.361,2.915,1.976,all P＞0.05). Conclusions Brucine inhibits the growth of liver cancer cells, by inducing increased apoptosis of the cells probably through FAS overexpression.

Objective To evaluate the clearance efficacy of resin hemoperfusion(HP) on the removal of organophosphorus in the rabbits poisoned by methamidophos(MAP) and its effects on organ injury. Method Six-teen healthy Japanese white rabbits were randomly divided into HP group and non-HP group. MAP was given through gastric tube in a dosage of 20 mg/kg to rabbits of both groups. Rabbits of liP group received resin hemop-ersion plus conventional treatment including early gastric lavage, atropine and pralidoxime. Rabbits of non-HP group received only conventional treatment. The plasma concentration of MAP was determined by using gas chro-matography before and after rabbits were poisoned at different intervals. Serum choline esterase (ChE),lactic de-hydrogenase (LDH), alanine aminotransferase (ALT), aspartate aminotransferase (AST), creatine kinase (CK) and creatine kinase isoenzyme (CK-MB) of rabbits of both groups were assayed 6 hours after rabbits poisoned. Pathological changes in lung, liver, kidney and muscle were investigated simutaneously. SPSS 10.0 software was used for statistical analysis. The comparison between groups was carried out by using t -test. Results ① The typical symptoms of organophospborus poisoning were occurred in rabbits within 5 - 10 minutes after ingestion of MAP. In HP group, the plasma levels of rabbits before,and 30 min,60 min,90 min and 120 min after hemoperfu-sion were (11.43±1.56),(7.82±1.54),(4.97±1.58),(5.66±1.75) ,(5.49±1.68) μg/mL, respectively (P <0.01). After hemoperfusion, the plasma MAP levels of rabbits in HP group were lower than those in non-HP groups (P < 0.01). The improveme, nt of clinical presentation of rabbits was observed shortly after HP. ② The blood choline esterase activity of rabbits were depressed in hoth groups without significant difference. In contrast, the blood levels of ALT, AST,LDH,CK and CK-MB of rabbits in non-HP group elevated significantly than in HP group (P < 0.01). ③ The more severe injury of muscle, liver, kidnet and lung of rabbits can could be seen in non-HP group. Conclusions ① HP can effectively eliminate the plasma MAP and has the potential to improve the clinical presentation of intoxication in rabbits. ② Early intervention of Hp exerts a protection from organ dam-age of organophosphorus pesticide.

Batch and continuous fermentation were adopted to investigate the effect of specific growth rate and amino acid components on RNA accumulation in Candida tropicalis ATCC 20408 in fermentation medium ( FM), yeast peptone dextrose medium (YPD), molasses fermentation medium ( MFM) and FM without corn steep liquor. The data showed that obvious differences in intracellular RNA accumulation were observed at different cell growth phases in bath fermentation prosess, and RNA level reached 11. 8% (g-RNA /g-DCW) during exponential phase, and only 6.9% during stationary phases. It was also found that intracellular RNA accumulation increased with the increase of specific growth rate in continue fermentation prosess, and the highest RNA level reached 15. 6% with the glucose conversion rate of 42. 8% at the dilution rate of 0. 5 h-1. Furthermore, the data showed that RNA lever was notably increased in batch fermentation process when amino acids or peptone was added into the fermentation medium containing no corn steep liquor. Taken together, it was reported for the first time that specific growth rate and amino acid components plays a leading role on the intracellular RNA accumulation in C. tropica lis, and specific growth rate is more important.
