OBJECTIVE:To detect and analyze the safety signals of pemetrexed in post-marketing,and provide references for rational drug use in the clinic. METHODS:A form of data mining techniques was used to detect the safety signals of pemetrexed in American adverse events reporting system and the analysis of signal effect factors i.e.,gender,age,dosage and indication was per-formed by SPSS 19.0. RESULTS:173 signals related to pemetrexed were excavated in 5 397 235 reports,and the number of report-ed adverse event in blood-lymphatic system was the most(491)and the number of signals in gastrointestinal system was the most (17). There was no statistical significance in the distribution of blood-lymphatic system and gastrointestinal system in gender(P=0.075) and age (P=0.726) compared to other system adverse event,but there was statistical significance in dosage (P=0.007) and indication(P=0.001). CONCLUSIONS:Adverse events induced by pemetrexed in blood-lymphatic system and gastrointestinal system should be monitored at the same time,especially combined with non-steroidal anti-inflammatory drugs.

Purpose To investigate the clinicopathological features, histogenesis, morphological characteristics, immunophenotypes and differential diagnosis of primary extragonadal yolk sac tumor ( eYST) . Methods Clinicopathological data, morphological charac-teristics and immunophenotypes results of 40 cases of eYST were retrospectively studied and the relevant literatures were reviewed. Re-sults All 40 patients, which included 24 male and 16 female, aged from 6 months to 42 years with a 12 years average age and 17 (42.5%) cases were over 12 years old. Mediastinum, sacrococcygeal, retroperitoneal, pineal gland and vagina were involved in 16 (40.0%), 12(30.0%), 5(12.5%), 4(10.0%) and 3(7.5%), respectively. All 40 cases included 32(80.0%) cases pure YSTs, while other 8(20.0%) cases contained other one or two types of germ cell tumor (GCT) components. Conclusions Primary eYST is rare, mediastinum and sacrococcygeal are the most common anatomic sites for eYST, and these mediastinal tumor patients are overwhelmingly confined to adult males, whose average age are significantly older than that in sacrococcygeal, retroperitoneal, pineal gland and vaginal tumor patients (P<0.05), while other sites eYST are restricted to prepubertal children. Adult eYST contain other types of GCT components in some cases, and children's counterparts are always pure YST. Extragonadal eYST manifestate pleomorphic histological features, which combine with immunohistochemical markers is definite value for diagnosis, differential diagnosis.

Objective To discuss the operative technical details in reducing complications after thyroid diseases reoperation, especially how to choose operative method and preserve laryngeal recurrent nerve and parathyroid gland. Methods The study protocols of 183 patients undergoing reoperation for thyroid disease from Jan. 2000 to Mar. 2009 were reviewed. There were 115 cases of benign and 68 cases of malignant thyroid diseases to observe the postoperative complications. Results The rates of temporary and permanent laryngeal recurrent nerve injury were 4.92% (9/183) and 1.64% (3/183), respectively. The rates of temporary and permanent hypocalcemia were 4.37% (8/183) and 0.55% (1/183), respectively. The rate of postoperative internal hemorrhage was 0.55%(1/183). Conclusions The thyroid reoperation was more difficult and can seduced a high rate surgical complication. The thyroid reoperation can be successfully performed if the operators could pay attention to the operative skill.

Objective To study the protective effects of aqueous extract and alcohol-soluble extract of Isodon lophanthoides var.gerardianus (Benth.)Hara (ILVG) on immunity hepatic injury induced by concanavalin A (Con A) in mice.Methods One hundred and eight NIH mice were allocated into normal control group,model group,ILVG groups of aqueous extract and alcohol-soluble extract (low-,middle-and high-dosage),and bifendate group randomly.In the experimental groups,mice received either ILVG aqueous extract or alcohol-soluble extract (18.20 g?kg-1,9.10 g?kg-1,4.55 g?kg-1 respectively) or Bifendate (45 mg?kg-1) by gastric perfusion daily for consecutive 5 days.In the 5th day,Con A (20 mg?kg-1) was injected into mice via the tail vein 4h after administration.And then the blood was obtained by picking out the eyeball and the serum was separated after 8-hour fasting.The serum levels of ALT and AST were analyzed,the body weight as well as the weight of liver,spleen and thymus were measured,and pathological features of hepatic tissue were observed.Results ILVG can decrease the ALT and AST,restrain the enlargement of liver and the shrinkage of thymus and reduce the necrosis of hepatic tissue.Conclusion Aqueous extract and alcohol-soluble extract of ILVG possess the effects of protecting liver from immunity injury induced by Con A in NIH mice.

OBJECTIVE:To study the effects of rAd-p53 injection on the proliferation,apoptosis and autophagy of nephroblas-toma cells. METHODS:Nephroblastoma cells were respectively cultured 20 h with high,medium,low concentration(1×109,1× 108,1×107 VP/mL)of Recombinant human rAd-p53 injection,cells with no injection were the blank control. Cell proliferation,cy-cle,apoptosis and related gene p21,Bax protein expressions were detected,and autophagy gene LC-3,Atg7,Atg12 expressions and number of autophagosomes were also detected. RESULTS:The proliferation inhibition rates of high,medium,low concentra-tion of Recombinant human rAd-p53 injection to nephroblastoma cells were(42.86±3.18)%,(33.64±7.25)%,(16.26±9.07)%;apoptotic rates were (53.85 ± 9.36)%,(37.35 ± 9.64)%,(23.64 ± 10.65)%,respectively. Compared with blank control,cells at period G0/G1 were increased under high,medium,low concentration Recombinant human rAd-p53 injection,effects were relatively obvious under high,medium concentration (P<0.05 or P<0.01);p21,Bax protein and LC-3,Atg7,Atg12 gene expressions were enhanced under high concentration,the number of autophagosomes was increased(P<0.01);Bax protein expression was en-hanced under medium concentration(P<0.05),the other indicators had no obvious changed(P>0.05). CONCLUSIONS:Recom-binant human rAd-p53 injection can inhibit the cell proliferation of nephroblastoma,and induce its apoptosis and autophagy.

Objective To observe the effects of Suoquan Wan(SQW) on the endocrine and immune function of the polyuria rats with kidney-yang deficiency. Methods The model rats were induced by gastric infusion of adenine(250 mg/kg) for 4 weeks, then treated respectively with SQW (at low, middle and high dose respectively), Shenqi Wan and desmopressin for another 4 weeks. The bodyweight and organ index were recorded, and serum cortisone concentration were detected. T cell subsets in peripheral blood were determined by flow cytometry. Results The bodyweight of rats in model group was lower than that in the normal control group. And the bodyweight of rats in desmopressin group, middle-and high-dose SQW groups differed from that in the model group (P
