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.

Objective To explore the differences and similarities of clinical characteristics,pathological features, treatment and prognosis between primary gastric lymphoma(PGL)and primary intestinal lymphoma (PIL). Methods The clinical characteristics, pathological features, therapeutic results, the detection of Helicobacter pylori (Hp) and prognosis of 48 PGL cases and 15 PIL cases were retrospectively analyzed. Results There was no statistical significance in age, gender, abdominal pain, gastrointestinal bleeding, B symptoms, clinical stage, mortality between PGL and PIL groups (P>0. 05). However, there were significant differences in the pathological type, acute abdomen emergency surgery between these two groups (P<0. 05). There was 12 Hp positive cases in mucosalassociated lymphoid tissue (MALT) lymphoma of PGL group (12/19), and 5 Hp positive cases in diffuse large B-cell lymphoma (DLBCL) (5/20). There was significant difference in Hp detection rate of these two pathological types. Hp was not found in PIL group. The Cox multivariate analysis indicated that stage Ⅲ-Ⅳ was the independent adverse factors affecting PGL prognosis (P<0. 05).Conclusions Mainly histological types are DLBCL and MALT lymphoma in PGL, and DLBCL in PIL.PIL predispose to T-cell lymphoma compared with PGL. MALT lymphoma is rare in PIL group. The mainly clinical stage is Ⅲ-Ⅳ both in PGL group and PIL group. Emergency surgery is often needed in PIL because of intussusception or perforation. The prognosis of PGL is correlated with the stage and the prognosis of PIL are correlated with the stage, B symptoms and T cell phenotype.

Objective To assess the relationship between muscle strength , creatine kinase ( CK) and electromyography ( EMG) in patients with lipid storage myopathy ( LSM).Methods Motor and sensory nerve conduction study, F wave, and quantity EMG were performed in 30 patients with LSM.Muscle strength and CK were studied before EMG.The relationship between EMG , muscle strength and CK were analyzed.Results EMG showed myopathic changes in 19 patients,myopathic coexistence with neuropathic changes in five , and neuropathic changes in two.Four patients had normal EMG.Motor nerve conduction studies showed decreased compound muscle action potential amplitude in seven nerves of two patients , while abnormal sensory nerve conduction in 16 nerves of five patients.Quantity EMG was performed in 78 muscles.Thirty-eight muscles of 21 patients had decreased amplitude and short duration motor unit potential ( MUP) , 6 muscles of 2 patients had increased amplitude and long duration MUP , and 30 muscles of 16 patients had normal MUP.Abnormal spontaneous activities ( SA) were detected in 16 muscles.The M( Q25 , Q75 ) of serum CK was 295.5 (201.0, 4 845.8) U/L in patients with abnormal SA in EMG , and 482.0 (292.8, 963.8) U/L in patients without abnormal SA in EMG (Z=0.281, P=0.778).Medical Research Council ( MRC) Scale in deltoid muscle was 4.3 ±0.7 in muscles with SA and 4.1 ±0.8 in muscles without SA (t=0.490, P=0.628), and that in quadriceps femoris was 3.9 ±0.6 for muscles with SA and 3.7 ± 0.6 for muscles without SA ( t =0.725 , P =0.474 ).MRC Scale in deltoid muscle was 4.1 ±0.7 in muscles with myogenic MUP and 4.1 ±0.9 in muscles without myogenic MUP ( t=0.101, P=0.920), which in quadriceps femoris was 3.8 ±0.6 for muscles with myogenic MUP and 3.7 ±0.7 for muscles without myogenic MUP ( t=0.368 , P=0.716 ).Conclusions Neurogenic or normal MUP and abnormal sensory nerve conduction can be presented in some patients with LSM , while SA is not common.The changes in MUP and SA are neither correlated with CK nor with muscle strength.

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.
