OBJECTIVE:To discuss the manifestation characteristics of mezlocillin injection-induced ADR.METHODS:Mezlocillin injection-induced ADR cases reported in domestic pharmaceutical journals between 1999 and July.2006 were retrieved from China Hospital Digital Library(CHDL) and analyzed statistically.RESULTS:The clinical manifestation of ADR induced by mezlocillin was characterized by allergic reactions or even anaphylactic shock.The major ADR types were first-using immediate type and the speedy outbreak type.CONCLUSION:Great importance should be attached to allergic reactions induced by mezlocillin injection.

OBJECTIVE:To discuss the general rules and characteristics of adverse drug reactions(ADRs)of lamivudine.METHODS:43national case reports of ADRs of lamivudine between1999and2005were classified and analyzed statistically.RESULTS:The affected patients ranged in age from8years to45years,with more males than females.There were no rules in the onset time of ADRs.The ADRS were mainly characterized by nervous system responses and aggravation of hepatitis in clinic.CONCLUSION:Great importance should be attached to ADRs of lamivudine to ensure the safety of drug use in clinic.

Plasma D-dimer is one of the degradation products of the cross-linked fibrin hydrolyzed by fibrinolysin and is also a unique metabolite of secondary fibrolysis.The change of its content is a reliable indicator for the identification of the hypercoagulabale state in vivo and primary and secondary fibrinolysis,as well as for the observation of the effectiveness of thrombolytic therapy.In recent years,D-dimer determination has gained new clinical application.

Objective To explore the influence of no drainage on pelvic lymphocyst following laparoscopic radical hysterectomy and pelvic lymphadenectomy . Methods A total of 105 patients with cervical cancer undergoing laparoscopic radical hysterectomy and pelvic lymphadenectomy in this hospital from January 2012 to February 2016 were divided into either non-drainage group (50 cases) or drainage group (55 cases) according to whether the pelvic drainage tube was placed after surgery .Comparative analyses on the incidence of postoperative complications such as pelvic lymphocyst were made between the two groups . Results No significant difference in lymphocyst rate was found between the two groups [27.3%(15/55) vs.24.0%(12/50), χ2 =0.147, P=0.702].The incidence of pelvic infection was lower in the non-drainage group (2.0%, 1/50) than that in the drainage group (14.5%, 8/55), but the difference was not statistically significant (χ2 =3.781, P=0.052).Other postoperative complications including urinary retention , urinary fistula, and deep venous thrombosis of lower limb had no statistical differences between the two groups (P>0.05). Conclusions Drainage after radical hysterectomy and pelvic lymphadenectomy for cervical cancer does not make a difference to the incidence of lymphocyst .Non-drainaging doesn ’ t increase the risk of infection .

Semaphorin 4D (SEMA4D), also known as CD100, is a protein that belongs to class IV semaphorin. Its physiologic role in the nervous system has been extensively explored. However, the roles of SEMA4D have extended beyond the traditionally studied territories. Collective data proved that SEMA4D has an important role in the regulation of immune system, angiogenesis, and tumorigenesis, among others. Specifically, SEMA4D enhanced the angiogenesis in malignant diseases. This review summarized the latest progression in the research on SEMA4D, including the structure, receptors, mechanism, and biological functions in tumor angiogenesis and progression.

Garcinol, a benzenetriol compound extracted from Garcinia cambogia, has antitumor activity, however, its antitumor mechanism remains unclear. The aim of this study was to investigate the role and mechanism of garcinol as a novel potential proteasome inhibitor. We applied the drug affinity responsive target stability (DARTS) method coupled to mass spectrometry to determine the binding protein of garcinol; the proteasome activity assay was used to determine the effect of garcinol on its hydrolase activity; immunofluorescence and proximity ligation assay (PLA) were used to detect the effects of garcinol on ubiquitin and RPN6; and flow cytometry were used to determine the effects of garcinol on cell apoptosis; and the anti-cancer effect was studied in organoid models. The results showed that RPN6 was a direct binding protein of garcinol; garcinol inhibited the hydrolase activity of proteasome, and induced the accumulation and aggregation of ubiquitin protein, and its proteasomal inhibitory effect was dependent on RPN6; further studies showed that garcinol induced oligomerization of RPN6 and formation of granules in the nucleus; finally, it was verified that garcinol induced apoptosis of tumor cells, and inhibited the growth of organoids of Apc^min/+ small intestine mice. These results suggest that garcinol is a potential proteasome inhibitor, which inhibits proteasome activity by directly targeting RPN6 on proteasome 19S, which in turn induces cell apoptosis and inhibits tumor growth.

Background The main mechanism of diabetic retinopathy (DR) is the formation of retinal neovascularization. Vascular endothelial growth factors (VEGF) is primarily factor for DR. Objective The goal of this study was to investigate the effects of angelicae sinensis decoction for supplementing blood ( ASD), a kind of traditional prescription of Chinese herbal medicine, on vascular endothelial growth factor (VEGF) level in vitreous and serum of STZ-induced type 2 diabetes mellitus. Methods Thirty-four SPF male SD rats were fed using high fat diet for 8 weeks and then the streptozocin of 25 mg/kg was intraperitoneally injected to create the type 2 diabetic models. ASD (3.6 g/kg) and 10 mg/kg Gli of 5 mi were administered intragastrically from the 4th day of high fat die though 8 weeks respectively. Other 10 matched rats were used as normal control group. The body weight, blood glucose level ,triglycerides (TG) and high density lipoprotein (HDL) were detected in 4 and 8 weeks after usage of drug. The vitreous and serum samples were obtained in the 8 th weeks for the VEGF detection by enzyme-linked immunosorbent assay (ELISA). This experiment comlied with the Regulations for the Administration of Affair Concerning Experimental Animals by State Science and Technology Commission. Results The body weight and HDL in DM group were significantly lower than those of normal control group in 4 or 8 weeks ( P＜0. 01 ), but in ASD and Gli groups ,the body weight and HDL were higher than those of the DM group (P＜0. 05 ). the blood glucose level and TG were elevated in DM group compared with normal control group (P＜0. 01 ), but those in ASD group and Gli group were decreased in comparison with DM group ( P＜0.05 ). EIISA revealed that no significant differences were found in VEGF levels between normal control group and ASD group or Gli group (P＞0. 05 ), but in DM group, the serum VEGF level (147.65±4. 55 ng/L) was reduced and vitreous VEGF level (673.45± 100. 85 ng/L) was raised,showing the considerable differences (P＜ 0.05 ). No any correlation was found between serum VEGF level and vitreous VEGF level (r=0.314,P＞0. 05). Conclusion ASD can decrease the VEGF level in vitreous,implying that ASD postpone the occurrence of diabetic retinopathy in DM rat.
