OBJECTIVE:To provide references for rational clinical application of human serum albumin. METHODS:By adopting retrospective analysis,medical records of 256 tumor inpatients administered with human serum albumin in the affiliated cancer hospital of zhengzhou university during Jan. and Jun. 2014 were randomly selected to statistically analyze the drug consump-tion amount per capita,average course of treatment and the concentration of serum albumin in the patient before administration. RE-SULTS:In our hospital,human serum albumin was used in 15 clinical departments,mainly in non-surgical departments. The pa-tients received drugs at a single dose ranging from 10 to 20 g. Postoperative patients with hypoalbuminemia topped the list in terms of daily consumption amount of human serum albumin(15.82 g/d)and patients with hypoalbuminemia accompanied by ascites and pleural effusion experienced the longest average course of treatment(6.93 d). Human serum albumin was mainly used for hypopro-teinemia. CONCLUSIONS:The use of human serum albumin in our hospital conformed to the dispensatory and the regulations on the medical insurance organizations of Henan Province. However,it is not in compliance with the regulations on the medical insur-ance organizations of Beijing and the guidelines of the hospital associations of American universities. Therefore,the indication of human serum albumin needs to be further defined,and priority should be given to nutrition supply for the inpatient with hypoalbu-minemia caused by malnutrition.

Objective To report a case of kerion caused by Geotrichum in China. Methods A 9 year-old-boy had kerion-form lesion on his scalp with swollen posterior auricular lymph nodes, and did not show other definite underlying disease. The pathogenic fungus was identified according to culture, scanning electron microscopy, biochemical tests and DNA sequencing. The hair infection test was performed and the infected hairs were examined by scanning electron microscope. Animal test confirmed the pathogenicity of the fungus. Results The fungal colonies were the same when the tissue cultures were repeated. The colonies showed milky white to yellowish in color. The hyphae could be identified at the periphery on Sabouraud′s agar culture at 27 ℃, which were moist and smooth on the surface at 37 ℃. Under microscope, there were many rectangular arthrospores, round or oval spores with or without buddings, as well as branched hyphae. The isolated fungus was identified as a Geotrichum silvicola by culture, scanning electron microscope, biochemical test and DNA sequencing. The patient′s condition was improved markedly after treatment of terbinafine for 4 weeks. Conclusions This is the first case report of kerion caused by Geotrichum in China, and terbinafine is effective.

Background Excessive production,deposition and contraction of extracellular matrix (ECM) of human lens endothelial cells (LECs) is one of main causes to posterior capsular opacification (PCO).Researches indicated that Wnt3a protein was involved in production of ECM and fibrosis in epithelial cells,but its effect on LECs is still unclear.Objective This study aimed to elucidate the roles of Wnt3a in production of ECM and gel contraction of LECs.Methods Lipofectamine-mediated transient transfection technique was used to introduce cDNA of Wnt3a gene and pcDNA3-HA vector into the LEC cell line SRA01/04 to act as Wnt3a transfection group and control group respectively.After 48 h of transfection,Western blot was used to detect the expression of Wnt3a,main components of ECM Col-Ⅰ,Col-Ⅳ and integrin β1.Immunofluorescence was used to detect the expression and distrubition of α-SMA and F-actin;collagen contraction was observed by mingling SRA01/04 cells with Col-Ⅰ.Results After 48 hours of transfection using lipofectamine 2000,the expressions of wnt3a protein in SRA01/04 cells was 0.703 ±0.105 in the wnt3a transfected group,and that in the control group was 0.290 ± 0.066,showing a significant difference between the two groups (t =5.782,P＜0.01).Western blot assay showed that the expression levels of Col-Ⅰ and Integrin β1 was 0.697±0.021 and 0.875±0.055 in the Wnt3a transfected group,and which was significantly higher than 0.370±0.020 and 0.580±0.030 in the control group (t =19.600,8.156,both P＜0.01).The expression level of Col Ⅳ in the Wnt3a transfected group was higher than that of the control group (0.430±0.020 vs 0.383 ±0.031),but the difference was not significant (t =2.514,P＞0.05).Immunofluorescence assay revealed that F-actin and α-SMA were weakly expressed in the cell membrane primarily in the control group,while they were strongly expressed in the cell membrane,cytoplasma in the Wnt3a transfected group.Tewnty-four hours after addtion of Col-Ⅰ,the gel contraction area ratio appeared to be more obvious in comparison with the 8 hours (64.1％ ±2.3％ vs 98.9％ ± 1.0％),and gel contraction area ratio was lower in the Wnt3a transfected group than that in the control group (64.1％ ± 2.3％ vs 93.9％ ± 3.1％).Conclusions The overexpression of Wnt3a activates the production of ECM,and the remodeling of celluar skeleton and cellular contraction.

This article was aimed to study the preparation process of glycyrrhetinic acid (GA)-tanshinone IIA (TSN)-salvianolic acid B (SalB) compound liposomes with 3-succinic-30-stearyl glycyrrhetinic acid (18-GA-Suc) which is one of amphiphilicglycyrrhetinic acid derivatives as targeting molecule. The structure of the targeting molecule was validated by 1H-NMR and 13C-NMR methods. The feed ratio of 18-GA-Suc was optimized through single factor test and the incorporation ratio of 18-GA-Suc was determined by low-speed centrifugation. Meanwhile, physicochemi-cal properties between Suc-GTS-Lip and GTS-Lip were compared. In vitro release studies of three components in Suc-GTS-Lip were conducted by equilibrium dialysis method. The results showed that the optimum conditions were when the feed ratio of 18-GA-Suc was 10%lipid liposomal membrane (mol·mol-1). It revealed that the incorpora-tion ratio of 18-GA-Suc was 96.58%, and the encapsulation efficiencies of GA, TSN, and SalB were about 86.15%, 81.70%, and 91.05%, respectively. In addition, the Suc-GTS-Lip was spherical and uniformly dispersed with parti-cle size of 128.7 nm and zeta potential of-15.5 mV. The release model of GA and TSN was fitted well with Higuchi equation, while SalB was fitted well with Hixon-crowell equation. It was concluded that Glycyrrhetinic acid deriva-tives (18-GA-Suc) can be successfully expressed in the liposome membrane, and the optimal preparation method of Suc-GTS-Lip was stable. All three components encapsulated into liposomes had sustained-release effects, which laid a good foundation for its further study about liver-targeting.

Objective To investigate effects of Baishile Capsules on cAMP-CREB-BDNF signal pathway about hippocampal neurogenesis in model rats with chronic unpredicted stress depression. Methods SD rats were randomly divided into blank group, model group, fluoxetine hydrochloride group, and Baishile Capsules high, medium, and low dose groups. Chronic stress depression rat model was established by chronic and mild unpredictable stressors. All groups were given relevant medicine for 21 days. The open-field test, sugar consumption experiment, place navigation test, and space searching experiment were used to detect behavior changes of the rats. ELISA was used to detect content of corticosterone in plasma. The protein expressions of PKA, BDNF, and CREB were detected by immunohistochemical method. Results Compared with model group, Baishile Capsules high dose and medium dose groups could remarkably increase the number of vertical and horizontal activities and 1% sucrose partial eclipse. Platform latency and target quadrant searching time decreased significantly in Baishile Capsules high dose group (P<0.05), and content of corticosterone in plasma increased obviously (P<0.05) in Baishile Capsules all dose groups. Protein expressions of PKA, CREB, and BDNF in hippocampal DG and CA3 area increased significantly (P<0.05) in Baishile Capsules high dose group. Conclusion Baishile Capsules can promote hippocampal neurogenesis through the cAMP-CREB-BDNF signal pathway and realize anti-depression effect.
