OBJECTIVE:To study the general pattern and characteristics of adverse drug reactions(ADR) induced by tinidazole.METHODS:Tinidazole-induced ADR cases reported in the internal pharmaceutical journals retrieved from Jan.1994 to Jun.2006 were analyzed statistically.RESULTS:The ADR induced by tinidazole were diversified in clinical manifestation,but allergic response was the most common type,followed by the lesion of nervous system and digestive system etc.CONC-LUSION:Clinicians should attach great importance to the ADR induced by tinidazole.

As the increasing of digital imagilag modalities,a close-at-hand challenge to deal with is the storage and transmission requirement of enormous data of medical images.Compression is one of the indispensable techniques to solve this problem.A comprehensive review and discussions are made in this paper over the medial image compression techniques applied in medical image domain,including the latest achievements in this field.Different compression algorithm including ROI-based coding,lossless compression,DWT,neural net are introduced and some quality evaluation methods are introduced.Foreground of the field is given from our point of view.

Objective To research the effect of letrozole combined with clomiphene on women with polycystic ovary induced infertility and the effect on matrix metalloproteinases-9(MMP-9),vascular endothelial growth factor(VEGF)and hepatocyte growth factor(HGF)levels.Methods 108 patients with polycystic ovary syndrome combined with infertility from February 2013 to August 2015 in our hospitolwere divided into control group and experimental group by lottery,54 cases in each groups,control group treated with clomiphene,the experimental group based on control group treatment with letrozole,the linical curative effect,MMP-9,VEGF and HGF level,sex hormones,insulin resistance index,adverse drug reactions of two groups were compared.Results The number of ovulation,advantage of ovulation number,normal rate of menstruation,ovulation rate and pregnancy ratesofin experimental group was higherthan the control group,the difference was statistically significant(P<0.05).The MMP-9,VEGF and HGF levels of experimental group was lower than the control group,the difference was statistically significant(P<0.05).The sex hormone level of experimental group was better than that of control group(P<0.05).The adverse reactions was no differences between the two groups.Conclusion The efficacy of letrozole combined with clomiphene in treatment of polycystic induced infertility,can inhibits MMP-9,VEGF and HGF expression,and with high safety.

Objective:To investigate the expression and correlation of EHD2 and E-cadherin in hepatocellular carcinoma (HCC). Meth-ods:Western blot and immunohistochemistry were used to detect the expression of EHD2 and E-cadherin in HCC specimens and adja-cent noncancerous tissues. The correlations of EHD2 and E-cadherin with the clinicopathological characteristics and prognosis of pa-tients were further analyzed using Pearsonχ2 test and Kaplan-Meier method. Results:EHD2 expression, along with E-cadherin, was markedly reduced in HCC tissues than in adjacent noncancerous tissues. Moreover, EHD2 and E-cadherin expression were correlated with histological grade, microvascular invasion, and lymph node metastasis (P<0.05). Kaplan-Meier survival analysis showed that HCC patients with decreased EHD2 and E-cadherin expression had shorter overall survival time than those with higher expression. Conclu-sion:The abnormal expression of EHD2 and E-cadherin possibly promote HCC. Detection of EHD2 and E-cadherin may be valuable for diagnosing HCC and evaluating malignancy extent and prognosis.

Objective:To investigate the expressions and their clinical significance of vascular endothelial growth factor (VEGF) and extracellular matrix (ECM) components in non-small cell lung cancer (NSCLC). Methods:Expressions of VEGF and ECM components (fibronectin, FN and collagen Ⅳ, cⅣ) in 50 cases of NSCLC tissues and 20 cases of normal lung tissues were detected by immunohistological analysis. Their relationship with clinical features of NSCLC and the correlation of expression of VEGF and Fn and cⅣ were analyzed.Results:The positive expression rates of VEGF, Fn, and cⅣ were 96%, 78%, and 50% in NSCLC tissues. The expressions of VEGF and Fn were significantly higher than those in normal lung tissues (P<0.05). The expression of Fn and over-expression of VEGF were associated with lymph node metastasis (r=1.00, P<0.001). The survival rate of patients with over-expression of VEGF was greatly lower than that with weak expression of VEGF (P=0.022). The survival rate of Fn-negative patients was markedly higher than that of Fn-positive patients (P=0.046). Conclusion:VEGF and ECM component Fn were highly expressed in NSCLC, which correlated with lymph node metastasis and survival rate. Expression of ECM and VEGF had positive correlations, suggesting that ECM might be one of the anti-angiogenesis targets for tumor therapy.

Objective:To make a prospective study on the effectiveness and safety of toremifene (TOR) combined with novelbine/cisplatin (NP) in the treatment of patients with advanced non-small cell lung cancer (NSCLC) whose first line platinum-based chemotherapy was failure. Methods:Forty-four patients with stage ⅡB-Ⅳ NSCLC, who failed in the first line cisplatin-based chemotherapy from January 2004 to February 2006, were enrolled in this study. All the patients received TOR combined with NP second line chemotherapy for two cycles. The response rate and adverse reaction were evaluated. The survival rate was analyzed.Results:The 44 patients received average 1.8 cycles of chemotherapy (1-3 cycles). The response of 37 patients could be evaluated including 21 patients who received NP regimen before and 16 patients who received platinum-based chemotherapy. After second line therapy, 4 of the 37 patients had partial response (PR), 19 had stable disease (SD), 14 had progressive disease (PD), and no patient had complete response (CR). The total response rate (CR+PR) was 10.8% (4/37). The disease-controlling rate (CR+PR+SD) was 62.2% (23/37). The response rate and disease-controlling rate of squamous cell lung cancer (SCC) were 27.3% (3/12) and 72.7% (8/12), which were significantly higher than adenocarcinoma [0% (0/18) and 44.4% (8/18), P<0.05]. The median survival time was 8.2 months, the median time for SD was 4.0 months (1.0-10.2 months), and the 1-year survival rate was 24.4%. The median survival time and 1-year survival rate of SCC patients had no significant difference compared with adenocarcinoma patients (9.2 vs 7.1 months; 33.3% vs 27.7%, P＝0.72). There was no significant difference in survival rate between male and female patients. One patient stopped therapy for liver function injury (hyperbilirubinemia). The adverse reactions induced by chemotherapy mainly included gastrointestinal reaction, bone marrow suppression, and liver function injury. No serious adverse reaction occurred. Conclusion:The clinical efficacy of second line TOR combined with NP regimen is similar with the first line regimen for NSCLC patients, especially for SCC patients. The frequency of adverse reaction is not increased.

0.05). Conclusions Autop-hagy/lysosomal pathway was activated immediately after recurrent seizures as indicated by the elevated expression of Beclin1 in cerebral cortex. 3-MA was involved in the regulation of autophagy/lysosomal pathway by down-regulating the expression of Beclin1.

Objective To discuss the diagnosis and surgical management of acute gangrenous cholecystitis (AGC) early after EST and ERCP. Methods Clinical and pathological data of 1468 cases receiving EST and ERCP in our hospital from 2005 to 2007 were retrospectively analyzed. Results AGC occurredin 16 cases and the incidence was 1.09%. Its main manifestations were pain in the right upper abdomen with local pertonitis and fever 1 to 3 d after operation, blood WBC exceeding 15.0× 109/L in 15 cases (93.8%), gallbladder tumefaction and double layer structure by B mode ultrasound, the diagnostic accuracy before operations was 81.3 %. We performed cholecystectomy in 10 cases, cholecystectomy and choledochotomy for common bile duct exploration and stone removal and T-tube drainage in 2, partial cholecystectomy in 3, cholecystostomy in 1. Pathological examination showedthat it was AGC in all the patients. Conclusion Latency in 1 to 3 d, local pertonitis, high blood WBC and B mode ultrasound are main managements in diagnosis of AGC and it should be diagnosed carefully distinguished from perforation and severe acute pencreatitis. It is suggested to undergoing early surgi-cal management once diagnosed definitely.
