Three different procedures of Guipi Oral Liquid have been studied. By comparison of TLC spots of n-buranol and n-hexane extracts from the sample and the UV absorption spectrum of the main component, ferulic acid, the rational production process was developed, which provides an experimental base for preparation improvement.

0.05).The recurrence of pterygium was related to the age.If the age increased five years,the risk of recurrence decreased 18.1%. Conclusion The application of MMC(during) the operation could decrease the recurrence rate of pterygium.The recurrence rate of pterygium was not related to the time of application of 0.02% MMC,and detainment for 3 min was enough during the operation.

Objective To study the time course of effect of methylene blue on inducible nitric oxide synthase (iNOS) mRNA transcription and protein expression in lung tissue of rats with sepsis, and its mechanism. Methods 126 female Wistar rats were randomly divided into sham group, sepsis group and methylene blue group. Each group was subdivided into 0-, 6-, 12-, 18-, 24-, 30-, and 36-hour subgroups according to the time after operation, with 6 rats in each subgroup. A model of sepsis was reproduced by cecal ligation and puncture (CLP), and the rats in sham group were only opened the abdominal cavity and isolated the membrane of the appendix without CLP. Rats in methylene blue group were given injection of 15 mg/kg methylene blue at all time points after CLP, the remaining rats were given 0.9%NaCl solution in same amount. Six hours after the injection, the rats were sacrificed and the lung tissue was harvested immediately. The expression of iNOS mRNA and protein in lung tissues were determined by real-time quantitative reverse transcription-polymerase chain reaction (RT-qPCR) and Western Blot respectively, and the changes in histopathology were observed using hematoxylin and eosin (HE) staining. Results Compared with sham group, the expression of iNOS mRNA was significantly up-regulated at 6, 12, 18 and 24 hours after CLP in sepsis group (2-ΔΔCt: 2.42±0.66 vs. 1.00±0.38 at 6 hours, P = 0.002; 2.54±0.76 vs. 1.00±0.27 at 12 hours, P = 0.000; 5.46±2.26 vs. 1.00±0.38 at 18 hours, P = 0.000; 3.03±0.62 vs. 1.00±0.33 at 24 hours, P = 0.001), and iNOS protein expression was significantly up-regulated at 12, 18 and 24 hours (gray value: 2.54±0.45 vs. 1.00±0.35 at 12 hours, P = 0.000; 2.65±0.64 vs. 1.00±0.33 at 18 hours, P = 0.000; 3.03±0.59 vs. 1.00±0.24 at 24 hours, P = 0.000). Compared with sepsis group, the expression of iNOS mRNA was significantly down-regulated at 6, 12, 18 and 24 hours in methylene blue group (2-ΔΔCt: 1.55±0.82 vs. 2.42±0.66 at 6 hours, P = 0.034; 1.84±0.42 vs. 2.54±0.76 at 12 hours, P = 0.016; 2.66±1.09 vs. 5.46±2.26 at 18 hours, P = 0.003; 2.20±0.29 vs. 3.03±0.62 at 24 hours, P = 0.002), and iNOS protein expression was significantly lowered at 12, 18 and 24 hours (gray value: 1.84±0.18 vs. 2.54±0.45 at 12 hours, P = 0.003; 1.87±0.27 vs. 2.65±0.64 at 18 hours, P = 0.008; 2.20±0.50 vs. 3.03±0.59 at 24 hours, P = 0.008). Histopathological observation showed that the degree of lung injury at each time point, including red blood cells effusion, lung interstitial edema, inflammatory cell infiltration, alveolar collapse etc., in sepsis group and methylene blue group were significantly higher than that of sham group, and the degree of lung injury in rats with methylene blue was not significantly improved as compared with that of sepsis group. Conclusions Lung iNOS mRNA expression was significantly increased at 6-24 hours after CLP induced sepsis in rat, and protein expression was increased at 12-24 hours. Methylene blue could inhibit mRNA transcription and protein expression of iNOS in lung of septic rat, but failed to reduce the degree of lung injury in sepsis.

Objective　To observe the effects of Ang-Ⅱ on expressions of c-fos mRNA and pro-α1［Ⅰ］mRNA in fibroblasts (FBC) of rat embryo in the course of collagen synthesis.Methods　The change of free Ca2+(［Ca2+］i) was tested in fluorometry and the expressions of c-fos mRNA and pro-α1［Ⅰ］mRNA were tested by RT-PCR method in incubated FBC.Results　The level of［Ca2+］i in FBC and the expressions of c-fos mRNA and pro-α1［Ⅰ］mRNA were enhanced with the increase of Ang-Ⅱ concentration(10-8～10-5and 10-7～10-6mol/L).Conclusions　The expressions of c-fos mRNA and pro-α1［Ⅰ］mRNA were induced by Ang-Ⅱ activating signal system in FBC.

Objective To investigate the clinical efficacy of nephrotic syndrome in children adjunctively treated by underatured lactalbumin.Methods Thirty-six cases of nephrotic syndrome were studied for about 1 year.The changes in red blood cells of reduced glutathione(GSH) were analyzed in 18 cases of underatured lactalbumin treatment group and 18 cases of control group.The clinical presentations were observed in both groups.Results GSH levels increased in underatured lactalbumin treatment group when compared with control group.The frequency of relapse and upper respiratory tract infection in underatured lactalbumin treatment group were significantly reduced compared with control group.Conclusion Underatured lactalbumin can provide support for the potential use of an antioxidant therapy in these patients.

OBJECTIVE: To observe the effects of Ginkgolides inhalation on eosinophils infiltration in airway of asthmatic guinea pig model. METHODS: Guinea pigs were divided into seven groups(n=8 in each group): model group, ginkgolides inhalation low, medium and high dosage groups(5, 10, 20mg?kg-1, respectively), ginkgolides ip group (at a dosage of 20 mg?kg-1), Dexamethasone ip group (at a dosage of 10 mg?kg-1), normal control group. The eosinophils (EOS) in bronchoalveolar lavage fluid (BALF) and trachea were counted. RESULTS: As compared with normal control group, the number of EOS in BALF was significantly increased in model group, but that in BALF and trachea of the Ginkgolides inhalation group was significantly reduced(P
