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.

The evolution of the quality control concepts of medical products within the global context and the development of the quality control technology of Chinese medicine are briefly described. Aimed at the bottlenecks in the regulation and quality control of Chinese medicine, using Big Data technology to address the significant challenges in Chinese medicine industry is proposed. For quality standard refinements and internationalization of Chinese medicine, a technological innovation strategy encompassing its methodology, and the R&D direction of the subsequent core technology are also presented.

This paper briefly analyzed and discussed the current status and major scientific challenges of traditional Chinese medicine (TCM) formulaology research. To promote formulaology research, a new strategy and corresponding technology, network formulaology, were proposed to reveal the complex interaction between functional chemome and biological responses network. The research framework and directions of network formulaology were also summarized and prospected.

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.
