OBJECTIVE: To study the compatibility stability of Chinese material medica injection for reference of clinical rational administration. METHODS: The pertinent literature about the compatibility stabililty of Chinese material medica injection during 1999-2006 retrieved from CHKD were statistically analyzed. RESULTS: The analysis on temperature, pH, corpuscle and concentration et exactly and directly revealed that Chinese material medica injection was stable under any infusion condition, which serves as reference for clinical medication. CONCLUTION: Because of the complexity of the components and process of preparation or extraction, the Chinese material medica injection often induce adverce reaction during intervenous drop infusion, thus great importance should be attached to the compatibility stability in centralized pharmacy admixture to ensure the clinical medication safety and decrease the incidence of adverse drug reaction.

Objective To analyze the surgical management and prognosis of hilar cholangiocarcinoma(HCC).MethodClinical data of 72 patients with HCC were retrospectively analyzed.Results There was a significant difference in the 3- and 5- year survival rates and median survivals among the groups treated with different surgical methods(x2 =28.1,P＜ 0.01 ).Univariate analyses conducted for the 16 factors which might affect prognosis showed the surgical method,lymphatic metastasis,positive margin,as well as the type of pathology and staging were of statistically significant prognostic value (P＜0.05).On a multivariate analysis using the Cox proportional hazards model,surgical management,lymphatic metastasis and the type of pathology and staging were independent prognostic factors (regression coefficient 1.4157,1.1072,1.6435).ConclusionRadical excision is an important prognostic factor for HCCa and extended resection improved the long-term survival rates of radical surgery.

Objective: To study the role of IL-6 in the dental pulp indirect injury by gunshot. Methods: The mandible was wounded by gunshot at (961.18?8.94) m/s in 17 dogs.2 h,6 h,1 d,3 d,7 d after injury molars,caspids,and lateral incisors were sampled respectively for IL-6 detection by immunohistochemical method in dental pulp. Results: The results showed that positive staining of IL-6 was observed predominantly in infiltrating inflammatory cells, vascular endothelial cells and some fibroblasts,IL-6 expression was consistent with the recruitment and activation of inflammatory cells, and with the severity duration of pulpal tissue injury and response. IL-6 level was increased in the dental pulp 6 h～3 d after injury.Conclusion: IL-6 is involved in regulating physiologic responses of dental pulp injuries in maxillofacial trauma by a projectile.

Objective To investigate the application values of thymosin α1 in severe sepsis.Methods Selected 94 patients with severe sepsis in our hospital from September 2014 to October 2016,were randomly divided into observation group(n=45)and control group(n=49),the control group was given routine treatment,the observation group was given thymosin α1 on the basis of conventional treatment,observed two groups before and after treatment T cell subsets and CD14+monocyte human leukocyte antigen(HLA-DR)and so on.Results The observation group the duration of ventilator use and ICU treatment were(12.51±3.82)d and(15.81±3.18)d,significantly shorter than the control group(P< 0.05).There was no significant difference in 28d mortality between the observation group and the control group; After treatment,the CD14+monocytes HLA-DR,CD3+and CD4+T cells in the observation group were significantly improved than before treatment(P<0.05);The HLA-DR,CD3+and CD4+T cells in the observation group after treatment were(36.04± 8.90)％,(58.93±8.74)％and(43.20±9.90)％,significantly higher than those in the control group(P<0.05);The observation group after treatment TNF-α,endotoxin and CRP respectively(56.40±11.78)ng/L,(27.83±9.98)ng/L and(53.20±9.73)g/mL,significantly lower than the control group(P< 0.05).Conclusion Application of thymosin α1 in the treatment of severe sepsis,which can improve the cellular immune function,adjust the state of inflammatory response,shorten the duration of mechanical ventilation and ICU stay.

Objective To study the growth inhibition of human hepatoma cells tranfected with type Ⅱ insulin like growth factor receptor (IGF ⅡR) antisense gene. Methods We constructed the recombinant eucaryotic expression plasmids of IGF ⅡR sense and antisense genes, which were transfected into SMMC 7721 human hepatoma cell line using calcium phosphate coprecipitation, and selected in DMEM supplemented with 500 ?g/ml G418(Geneticin) for 2～3 weeks. Then the total number of colonies formed was counted. The effect of IGF ⅡR antisense gene transfection on endogenous IGF ⅡR mRNA levels was examined by Northern blot, and the growth rate and the ability of the transfected cells to form colonies in soft agar medium were also examined. Results The hepatoma cells transfected with IGF ⅡR antisense gene exhibited significant reduction in endogenous IGF ⅡR messenger RNA(mRNA) levels and loss of their ability for anchorage independent growth in soft agar. The IGF ⅡR antisense gene supressed the formation of colonies of SMMC 7721 cells resistant to G418 without alteration on cell growth curve. Conclusion The IGF ⅡR antisense gene expression effectively blocks IGF Ⅱ to IGF ⅡR autocrine and/or paracrine signal transduction pathway and reverses certain aspects of the cell malignant phenotype.

AIM To evaluate the antagonizing activity of iQWcF, a modified tripeptide, to endothelin receptors. METHORDS ①Vasoconstriction experiments with aorta strips of rats. ② In vivo experiments:male normotensive Wistar rats were anesthetized with pentobarbital Na (50 mg?kg -1 ),and catheterized into the carotic artery for measurement of blood pressure, and into the femoral vein for administration of iQWcF (30 mg?kg -1 ) and ET 1(0 9 nmol?kg -1 ). The test compound was given intravenously 5 min before the bolus injection of ET 1. Control animals received saline on the same time schedule.The blood pressure was recorded at different time interval after injecting ET 1. RESULTS ①iQWcF prohibited the vascontriction of aorta induced by ET 1 in a concentration dependent fashion.②The compound(30 mg?kg -1 .iv) markedly antagonized ET 1 induced the long lasting pressor phase mediated by ET A without affecting early transient depressor phase by ET B. CONCLUSION iQWcF is one of ET A selective antagonists.

Objective To explore the changes and significance of somatostatin (SS) and acetylcholine (Ach) contents in vascular dementia rats. Methods Model of vascular dementia rats was established. Active avoidance responase (AAR) ratio was used as the index for the judgement of the learning and memory abilities of vascular dementia rats. The SS and Ach contents in different cerebral sections of rats with and without intervention of huperzine A were determined by radioimmunoassay. Results A remarkable decrease in SS and Ach contents was found in vascular dementia rats, which could be reversed by intervention of huperzine A. Conclusion The decreased SS content in cerebrum after ischemia is related with vascular dementia. SS may be involved in the pathological process of vascular dementia through the mutual regulation with Ach.
