Objective To investigate the effects of resistin on mesangial cells proliferation induced by high glucose and subsequent change of p38MAPK signal pathway. Methods Human macrophrages were cultured and treated with adenovirus encoding for resistin (Ad-resistin) for 48 h and were then co-cultured with human mesangial cells stimulated by high glucose for another 48 h. Mesangial ceils were harvested and their proliferation was measured by 3H-TdR. Activator protein 1 (AP-1) was examined by immunocytochemistry and laminin of excellular matrix was observed with immuofluorescence. Protein levels of p38MAPK and TGF-β1 were measured by Western blot. Smad2 phosphatase activity was aslo detected by Western blot. Results The mRNA and protein levels of resistin were significantly higher in Ad-resistin treated macrophages than those in Ad treated cells (P<0.01). Over-expression of resistin up-regulated p38MAPK protein levels of human mesangial cells(P<0.05). Resistin also promoted the proliferation of mesangial cells (P<0.01) and the synthesis of laminin stimulated by high glucose. The expression of TGF-β1 and phosphorylation of Smad2 were up-regulated in the mesangial cells (P< 0.05). Conclusion Macrophage cytokine resistin may promote mesangial cells proliferation and abnormal accumulation of excellular matrix stimulated by high glucose via activating p38MAPK signal passway.

To investigate the potential use of synthetic stabilized ribozymes for the treatment of chronic hepatitis C virus (HCV) infection,we designed and synthesized 2 hammerhead ribozymes (Rz213 and Rz498) targeting conserved sites in the 5′noncoding region (NCR) and C gene of HCV RNA.Constructed to the eukaryotic vector pcDNA3, the two ribozymes were respectively or simultaneously transfected with lipofectamine into WISHnc transgenic cells, which could express permanently HCV C luciferase protein under the control of HCV 5′NCR.The expression of C luciferase was measured by luminometer.The results showed that the luciferase activities were significantly down regulated in the WISHnc cells, and the inhibitory rates were 42.94%～67.81% within 7 days after ribozymes transfection. There was no significant differences between Rz213 or Rz498 and co transfection, but adding the target site of ribozymes might prevent host cells from the loss of ribozyme therapeutic effect due to viral gene mutation.

Objective: To develop an HPLC method for the simultaneous determination of 3 ultraviolet absorbers (benzylidene camphor sulfonic acid, camphor benzalkonium methosulfate, 4-methylbenzylidene camphor) in cosmetics.Methods: After extracted by acetonitrile-methanol-ammonium acetate aqueous solution-tetrahydrofur(30∶35∶30∶5, v/v)(for lotion and milk) or acetonitrile-methanol-ammonium acetate aqueous solution(30∶20∶50, v/v)(for cream and powder), the UV absorbers were separated on a Thermo scientific C18 column (250 mm×4.6 mm,5 μm) at 35 ℃ with methanol, acetonitrile and 0.02 mol·L-1ammonium acetate aqueous solution (pH 5.15 adjusted by glacial acetic acid) as the mobile phase with gradient elution at the flow rate of 1.0 ml·min-1, and then analyzed by a DAD detector at the wavelength of 288 nm and 300 nm.Results: Benzylidene camphor sulfonic acid, camphor benzalkonium methosulfate and 4-methylbenzylidene camphor showed good linearity within the range of 12.26-98.06 μg·ml-1(r=0.999 9), 9.31-74.48 μg·ml-1(r=0.999 9) and 6.86-54.88 μg·ml-1(r=0.999 9), respectively.The limit of detection (LOD) and the limit of quantitation (LOQ) were 4.6, 6.4 and 1.6 ng and 17.4, 15.9 and 5.5 ng, respectively.The average recovery was 99.2%(RSD=1.58%), 99.8%(RSD=2.38%) and 99.2%(RSD=2.03%)(n=36), respectively.Conclusion: The method is simple, rapid, reproducible, accurate and reliable, and can be applied in the determination of ultraviolet absorbers in cosmetics.

Objective To observe the clinical curative effect of combination of traditional Chinese and western medicine for treatment of patients with hepatitis B virus (HBV) related acute-on-chronic (subacute) liver failure (ACLF). Methods A prospective randomized controlled trial was conducted; 66 cases of HBV-ACLF patients were randomly divided into two groups: a test group (44 cases) and a control group (22 cases). Conventional western medicine treatment was given to both groups; the patients in test group additionally received the traditional Chinese medicine (TCM) in accord to the principles of differentiation of syndromes in TCM, in cases with damp-heat and blood stasis syndrome with yellow appearance, Liangxue Jiedu Huayu decoction (Paeoniae Radix Rubra 60 - 150 g, Artemisiae Scopariae Herba 30 - 90 g, Gardeniae Fructus 9 - 12 g, Hedyotis diffusa Willd 20 - 30 g, Salviae Miltiorrhizae Radix et Rhizoma 30 g, Atractylodis Macrocephalae Rhizoma 30 g, Rubiae Radix et Rhizoma 30 - 45 g, Siegesbeckiae Herba 30 - 45 g, Bletillae Rhizoma 15 g ) was given, in cases with Qi deficiency and blood stasis with yellow appearance, Yiqi Jiedu Huayu decoction (Astragali Radix Preparata Cum Melle 30 g, Pseudostellariae Radix 15 g, Artemisiae Scopariae Herba 30 - 60 g, Polygoni Cuspidati Rhizoma et Radix 15 - 30 g, Salviae Miltiorrhizae Radix et Rhizoma 30 g, Aconiti Lateralis Radix Preparata 10 - 15 g, Atractylodis Macrocephalae Rhizoma 30 g, Rubiae Radix et Rhizoma 30 - 45 g, Siegesbeckiae Herba 30 - 45 g, Gigeriae Galli Endothelium Corneum 20 g) was given, the dosage in both groups being 1 dose daily, one dose was prepared to a water decoction 250 - 300 mL which was divided into two parts, one part taken twice a day; the control group received only western medicine treatment. After 2 weeks of treatment, the clinical comprehensive curative effect, the syndrome score efficacy, and the changes of main indexes of liver function,cholinesterase (ChE), albumin (Alb), prothrombin activity (PTA) were observed in the two groups.Results The clinical total efficacy in the test group was significantly higher than that in the control group [75.0% (33/44) vs. 45.5% (10/22),P < 0.05]. The syndrome score total efficacy in the test group was also higher than that in the control group [75.0% (33/44) vs. 63.6% (14/22)], but the difference was not statistically significant (P > 0.05). After treatment, the alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBil) and direct bilirubin (DBil) were all lower than those before treatment in both groups, while the ChE, Alb and PTA were higher than those before treatment, and the degree of changes was more significant in the test group [test group: ALT (U/L): 63.28±99.28 vs. 574.58±571.08, AST (U/L): 86.84±92.88 vs. 438.20±482.74, TBil (μmol/L): 161.90±178.34 vs. 269.46±95.10, DBil (μmol/L): 115.32±126.51 vs. 209.12±79.78, ChE (U/L): 4 239.14±1 505.00 vs. 3 341.49±1 609.40, Alb (g/L): 32.65±4.77 vs. 29.73±3.31, PTA: (69.69±44.92)% vs. (32.84±7.47)%; control group: ALT (U/L): 93.28±93.86 vs. 365.24±376.98, AST (U/L): 126.26±121.35 vs. 287.17±301.04, TBil (μmol/L): 226.80±187.38 vs. 281.02±103.73, DBil (μmol/L): 172.50±147.32 vs. 227.96±87.20, ChE (U/L): 4 484.66±1 886.53 vs. 3 918.77±1 417.77, Alb (g/L): 33.17±4.76 vs. 30.47±3.03, PTA: (63.80±36.80)% vs. (33.96±6.32)%,P < 0.05 orP < 0.01].Conclusion The combination of TCM and western medicine for treatment of HBV-ACLF can improve liver function, and the prognosis is superior to using western medicine treatment alone.

The paper is to systematically evaluate the efficacy and safety of Deng Zhan Xi Xin injection ( DZXXI) as an adjuvant treatment for patients with angina pectoris. The Cochrane Library, Medline, EMbase, CBM, CNKI, VIP, and Wan fang Data base were searched. Randomized controlled trials (RCTs) of DZXXI combined with western medicine routine treatment versus western medicine routine treatment alone for angina pectoris patients were all included. All trials were assessed according to the Cochrane Reviewer' s Handbook 5.1 for Systematic Reviews of Intervention and Meta analyses were performed by RevMan 5. 2 Software. A total of 30RCTs (3 086 patients including 1 572 patients of treatment group and 1 514 patients of control group) were included. Meta-analysis of treatment group compared with control group showed superior effect over reducing cardiovascular events ( OR = 0.33; 95% CI: [0.16, 0.67], P = 0.002, improving effective rate of DZXXI as adjuvant treatment for angina pectoris patients (OR = 3.97; 95% CI: [3.15, 5.02]; P < 0.000 010 and electrocardiogram curative effect (OR = 2.21; 95% CI; [1.83, 2.68]; P < 0.000 010. Funnel figure seemed that there was publication bias. The current limited evidence showed that when compared with the control group, treatment group was superior in improving patients with angina pectoris. But based on the limitations of the study, rigorous design with long follow up clinical trials are necessary for further evidence.

0.05) between the Zhuang and Han races.3. The sagittal diameter and shape of the spinal canal were not consistent with the external feature of the cord at C_3—C_6 vertebral levels where the sagittal diameter became physiologically reduced and at C_4 (12.92mm) it was the narrowest.4. Forms of the spinal canal (except C_1) were divided into four different types: a) circular, b) triangular, c) transitional and d) scalene.The shape of the spinal canal at C 1,2 the circular and it changed gradually from a semicircular to a triangular type at C_6 (81.31%). The triangular type then assumed the shape of a clam and polygon and become the circular type at T_6 (84.76%). The circular type became triangular again and assumed the shape of a clam at L_5 (99%). The triangular shape tended to assume the shape of a trefoil and then a bell from L_3 to L_5. The percentage of the trefoil shape of the lumbar vertebral canal was 5.02%.The results of the present study support the views of Eisenstein: i. e. the trefoil configuration is a common non-pathological condition, and is not necessarily dependent on, or related to, increasing age, osteophytosis or spinal stenosis. It is probably a developmental variation of normal anatomy.

The acute iv and ig LD50 of sudoxicam synthesized by Shanyan Ph-armaceutic College was calculated to be 135?10. 7 and 320 ? 96 mg/kg in mice. In polyarthritic rats, Sud at 2 and 4 mg/kg/d for 28 days did not induce changes in serum AKP, SGPT, BUN the morphal-ogic characteristics of the gastrointestinal tract, liver and kidney. In 3 dogs orally given Sud 16 mg/kg/d for 5 consecutive days, 2/3 died at days 10 to 13. In other 3 dogs given Sud 16 mg/kg/d every other day, plasma concentrations of Sud were determined by ultra violet spectrophotometry. It was found that on the days 10 to 20 , the concentration time curves had attained a intoxicant steady state with plasma sudoxicam concentrations as high as 44. 9 ? 73. 9?g/ml ,and all of them died after 17~25 days. Their bleeding time and coagu- lation time were prolonged to 2 or 3 times of the control and serum BUN was increased. In one dog autopsy revealed the interstitial inflammation of the kidney and small local necrosis of the live, but not in other dogs.Gastric ulceration in rats can be produced by the oral administration of verious doses of Sud. The UD50 of Sud was 15.47mg/kg. It was found that the gastric ulceration in rats is related to the plasma levels
