To study and observe the changes of serum, aqueous humor and tear lL - 2, slL - 2, NO, TAC, and SOD of patients with cataract.
●METHODS: Totally 60 patients with cataract in our hospital from November 2011 to September 2013 were included as the observation group, and 60 patients with eye traumas were as the control group. The serum, aqueous humor and tear lL - 2, slL - 2, NO, TAC, and SOD of two groups were detected and compared, and the detection levels of patients with different stages were compared.
●RESULTS: The serum, aqueous humor and tear lL-2, TAC, and SOD of observation group were all lower than those of control group, the slL-2 and NO were all higher than those of control group. The serum, aqueous humor and tear detection levels of patients at different stages had obvious differences, and the aqueous humor lL - 2 were lower than those of serum and tear, the slL-2 were higher than those of serum and tear, with statistically significant differences.
●CONCLUSlON: The change of serum, aqueous humor and tear lL-2, slL-2, NO, TAC, and SOD of patients are all great, and the influence of the stages for those indexes are great too, the inflammatory response state of aqueous humor are more obvious.

Some immune responses induced by atherosclerosis may aggravate the state of the illness by inducing persistent arterial inflammation, whereas others may inhibit arterial inflammation and atherosclerosis.Thus, the prevention and treatment of atherosclerosis may be achieved by the method of immunomodulation, by which selectively suppress proatherogenic immune responses or activate antiatherogenic ones.

Using chemically defined medium as the control, mechanism of corn steep liquor (CSL) in complex medium during glycerol production by Candida glycerinogenes was studied.The results showed that there were three key factors in CSL that had some great influences on glycerol fermentation of C.glycerinogenes, including phosphorus, nitrogen, and trace elements.The maximum glycerol yield of 53.44% was achieved at an optimal phosphorus concentration of 121.75mg/L, where the CSL concentration was 14g/L.Phosphorus in CSL could control the distribution of carbon metabolism flux between EMP pathway and HMP pathway.With the increase in CSL concentrations, superfluous phosphorus could restrain HMP pathway and activate EMP pathway, thus resulting in remarkable changes in various fermentation parameters of complex medium.Nitrogen in CSL could play a cooperative role in the regulative function of phosphorus.However, it was not a suitable nitrogen source for C.glycerinogenes.Trace elements in CSL could markedly improve the glucose consumption rate, accelerate the cell growth, and enhance the glycerol yield.

To establish a rat model of diabetes-associated cerebral ischemia due to qi and yin deficiency and blood stasis, and to investigate the effects of Radix Ginseng, Rhizoma Chuanxiong, Rhizoma Polygonati Odorati and Rhizoma Polygonati Sibirici Granule (Shenxiong Yujing Granule), which has the function of strengthening qi, nourishing yin, and activating blood, on proliferation, differentiation and survival of neural cells in rats with diabetes-associated cerebral ischemia.

Aim To investigate whether ischemic postconditioning could induce ischemic tolerance to focal cerebral reperfusion injury and comparison with ischemic preconditioning. Methods A reversible middle cerebral artery occlusion (MCAO)was used in this study. Fifty male Sprague-dawley rats were randomized into five groups(n=10): sham-operated group,MCAO group,preconditioning group, postconditioning group and nimodipin group . The neurological function was scored and the infarct volume was measured after operation. The grouping,experimental methods and procedures of another fifty rats were as above except that ipsilateral brain of infarction was dissected and made into homogenate,then the contents of MDA,SOD,GSH and LA were quantitatively measured. Results The postconditioning and preconditioning improved the neurological function,reduced the cerebral infarction volumes and cerebral swelling significantly compared with those of the MCAO group. Contents of LA and MDA were lower, while the activity of SOD in the brain tissues were higher in preconditioning group and postconditioning group than those of the MCAO group. Conclusion Postconditioning could induce brain tolerance, and increase the antioxidant activity, which might be an important mechanism of induction of brain tolerance.

Objective To investigate the role of Xuebijing injection in inhibiting perioperative inflammatory responses and protecting the function of multiple organs.Methods A single-blind,randomized,parallel controlled trial was conducted.60 patients in the First Affiliated Hospital of Zhejiang University School of Medicine,aged 18 to 80 years,ASA grade Ⅰ-Ⅲ,undergoing elective abdominal surgery,were enrolled.The patients were randomly divided into the control group (n =30) and the treatment group (n =30).In the control group,after induction of anesthesia,a continuous infusion of 0.9％ normal saline (NS) 200 mL was given in a speed of 2 mL/min,while a continuous infusion of Xuebijing 2 mL/kg in 100 mL of 0.9％ NS was given at 2 mL/min in the treatment group after induction of anesthesia.The blood sample was drawn,and body temperature,routine blood test,C-reactive protein (CRP),liver and kidney function,fasting glucose (Glu),and serum interleukin-6 (IL-6),high mobility group protein B 1 (HMGB 1) levels were determined in all the patients before anesthesia (T1),at the end of operation (T2),12 hours after operation (T3),or at 5:00 am on the third day after operation (T4).At the same time the adverse reactions were recorded for evaluation of the safety of Xuebijing.Results After using Xuebijing injection,T3 body temperature and the T3-T1 temperature difference in treatment group were significantly lower than those of the control group(℃℃:36.70 ± 0.37 vs.37.38 ± 0.47,t＝6.199,P＝0.000; 0.07 ± 0.50 vs.0.85 ±0.58,t＝5.598,P＝0.000).Postoperative white blood cell count,neutrophil percentage,and CRP were significantly higher than those before the operation,but the differences between two groups were not statistically significant.Compared with the control group,alanine aminotransferase (ALT),aspartate transaminase (AST),total bilirubin (TBil) levels at T3 of treatment group were significantly reduced [ALT (U/L):17.56 ± 9.80 vs.88.60 ± 179.76,AST(U/L):27.53 ± 13.12 vs.84.16 ± 151.14,TBil(μ,mol/L):15.46 ± 9.79 vs.25.63 ± 25.33,all P＜0.05].Difference of conjugated bilirubin (CB),blood urea nitrogen (BUN),creatinine (Cr),Glu were not statistically significant between two groups.IL-6 showed an increasing trend after the operation in both groups,and IL-6 level (ng/L) at T2 of the treatment group was significantly lower than that of the control group (41.42 ± 59.74 vs.124.84 ± 119.66,t=3.405,P=0.001).The HMGB 1 level of two groups at T4 were lower than those at T1,but it decreased significantly only in treatment group (μg/L:22.03 ± 15.73 vs.45.09 ± 33.79,P＜0.05),and there was no significant difference between two groups.No serious adverse events occurred during the clinical trial.Conclusions Application of Xuebijing injection during anesthesia can significantly diminish postoperative inflammatory injury,which plays an important role in the protection of liver function,helps restore organ function and improve prognosis,and it is safe and effective.

Objective: To compare the efficacy difference between moxibustion at sensitized-acupoints and non-sensitized- acupoints using the same group of acupoints. Methods: A total of 139 patients with chronic superficial gastritis were divided into a sensitized acupoint group (102 cases) and a non-sensitized acupoint group (37 cases) based on whether acupoint sensitization occurred. The SPSS version 19.0 statistical software propensity score matching function was used to balance the baseline data between the groups. Finally, 29 pairs of matched patients were included, namely 29 cases in the sensitized acupoint group and 29 cases in the non-sensitized acupoint group. Both groups were treated with moxibustion therapy. The treatment lasted for 30 min per time, and was performed every other day for 8 weeks. Changes in the traditional Chinese medicine (TCM) symptom score and the short-form 36-item health survey (SF-36) score in both groups were observed before and after treatment, as well as the clinical efficacy. Results: The covariates of age, course of disease, TCM symptom score and SF-36 score in the two groups were balanced after matching (all P>0.05). After treatment, the total effective rate was 100.0％ in the sensitized acupoint group and 79.3％ in the non-sensitized acupoint group. The difference in the total effective rate between the two groups was statistically significant (P<0.01). After treatment and at the 4-week follow-up, the TCM symptom scores in the sensitized acupoint group were significantly lower than those in the non-sensitized acupoint group (all P<0.01); the SF-36 scores in the sensitized acupoint group were significantly higher than those in the non-sensitized acupoint group (all P<0.01). Conclusion: With the same group of acupoints, the sensitized acupoints have a better therapeutic effect and long-term efficacy than the non-sensitized acupoints in the treatment of chronic superficial gastritis.

SMART-RACE was performed after isolating the total RNA of Armillariella tabescens to amplify the full-length cDNA of arabinosidase (GenBank Accession No. AJ620046). Bioinformatics analysis was used to analyze the code frame of arabinosidase, to predict its structure and function. Recombinant plasmid pPIC9-AF was constructed and then electroporated into methylotrophic yeast Pichia pastoris GS115. The secreted 6 ? His fusion protein was purified to analyze its enzymology property. This arabinosidase had high activity at 30-35℃ under acid condition, and was stable within wide range of pH and temperature. It maintained about 80% activity at the range of pH4. 0-8.0 and 20-40℃,wider than many other cloned arabinosidase. So it was worthy to go step further to study this enzyme, and recombinant expression provided a chance of highly expressing arabinosidase.
