ABSTRACT

Objective To investigate the effect and safety of Gukang capsule combined with sodium hyaluronate injection on the treatment of the patients with osteoarthritis. Methods 94 osteoarthritis patients selected from December 2015 to March 2017 were randomly divided into study group (n=47) and control group (n=47). The control group were given sodium hyaluronate injection, the study group were received local injection of sodium hyaluronate combined with Gukang capsule. The changes of knee joint function (HSS scale score) and adverse reaction rate were recorded and compared before and after treatment in the two groups. Results Before treatment, there was no significant difference in HSS scores between the two groups. After treatment, the HSS score in the study group was significantly better than that in the control group (P<0.05). There were no significant differences in the adverse reactions between the 2 groups during the treatment. Conclusion Local injection of sodium hyaluronate combined with Gukang capsule on the treatment of osteoarthritis, which can significantly improve the clinical efficacy, the security is higher. .

ABSTRACT

Abstract?AIM: To obtain the prevalence and risk factors of symptomatic dry eye disease ( SDED ) among college students in China.?METHODS:Population-based cross-sectional study. Students in Medical School of Lanzhou University were approached. A questionnaire was used to evaluate the prevalence of SDED and its risk factors. The diagnosis of SDED was based on reported symptoms and was established if the participants reported “often” or “all the time” once or more for 6-item questionnaire. Positive tests included a tear-film breakup time ( TBUT)≤10s and a fluorescein staining score ( FSS ) ≥1. Demographic information and possible factors that may contribute to SDED were analyzed in a step-wise multivariate logistic regression modelto assess risk factors of SDED.? RESULTS: There were 1139 participants ( 84. 37%response rate ) have completed the questionnaire, 475 males and 664 females aged 16-26y. The prevalence of SDED was 18. 70% [95% confidence interval ( CI)= 16. 59-20. 81]. A TBUT of ≤10s and a FSS≥1 were noted in 47. 67%(95% CI=44. 95-50. 57) and 13. 97%(95% CI=11. 95-15. 99) for all participants, respectively. The multivariate regression analysis revealed the following risk factors:daily reading time of≥4h(OR=1. 58,95% CI=1. 15-2. 18), daily computer use of≥4h ( OR= 1. 52, 95% CI= 1. 02-2. 25), and constant eyeglasses wearing (OR=1. 54,95%CI=1. 08-2. 13). The female gender, refractive surgery and contact lens ( CLs) wearing were not risk factors for SDED in this analysis.? CONCLUSION: The prevalence for SDED is high in Chinese college students. The risk factors include daily reading time of≥4h, daily computer use of≥4h and constant eyeglasses wearing.

ABSTRACT

PURPOSE: The degradation of the extracellular matrix has been shown to play an important role in the treatment of hepatic cirrhosis. In this study, the effect of thalidomide on the degradation of extracellular matrix was evaluated in a rat model of hepatic cirrhosis. MATERIALS AND METHODS: Cirrhosis was induced in Wistar rats by intraperitoneal injection of carbon tetrachloride (CCl4) three times weekly for 8 weeks. Then CCl4 was discontinued and thalidomide (100 mg/kg) or its vehicle was administered daily by gavage for 6 weeks. Serum hyaluronic acid, laminin, procollagen type III, and collagen type IV were examined by using a radioimmunoassay. Matrix metalloproteinase-13 (MMP-13), tissue inhibitor of metalloproteinase-1 (TIMP-1), and alpha-smooth muscle actin (alpha-SMA) protein in the liver, transforming growth factor beta1 (TGF-beta1) protein in cytoplasm by using immunohistochemistry and Western blot analysis, and MMP-13, TIMP-1, and TGF-beta1 mRNA levels in the liver were studied using reverse transcriptase polymerase chain reaction. RESULTS: Liver histopathology was significantly better in rats given thalidomide than in the untreated model group. The levels of TIMP-1 and TGF-beta1 mRNA and protein expressions were decreased significantly and MMP-13 mRNA and protein in the liver were significantly elevated in the thalidomide-treated group. CONCLUSION: Thalidomide may exert its effects on the regulation of MMP-13 and TIMP-1 via inhibition of the TGF-beta1 signaling pathway, which enhances the degradation of extracellular matrix and accelerates the regression of hepatic cirrhosis in rats.

ABSTRACT

Objective To understand epidemiological characteristics of self -reported acute gastroenteritis in Hangzhou -Jiaxing -Huzhou area in Zhejiang Province.Methods According to the population capacity,the household interview was conducted among families selected by multi stage sampling method from July 2010 to June 2011,and one person who was approaching birthday in every family was selected for investigation, including symptoms and treatment of acute gastroenteritis.Results Totally 9 548 people were investigated.The monthly prevalence of acute gastroenteritis among the surveyed population was 2.95% and the incidence was 0.39 per person year.It was estimated that there would be 5.875 6 million cases of acute gastroenteritis occurred during this year in the area.Logistic regression analysis showed that monthly prevalence in female was higher than in male.The monthly prevalence reached the high level in July and August.The monthly prevalence in preschool children was the highest.The monthly prevalence in rural population was higher than that in the urban population.Besides,the monthly prevalence in those of family number ≥3 was higher than that of family number less than 3.Totally,56.38% of the cases visited docter,and 54.67% of the cases took antibiotics;13.48%reported work absence and 2.13% reported school absence due to the illness.Conclusion The disease burden of acute gastroenteritis could be heavy in Hangzhou -Jiaxing -Huzhou area.Gender,education,season,residence and the size of family may have some effects on the occurrence of acute gastroenteritis.

ABSTRACT

Plenty of data and tests suggested that flavonoids have strong physiological and pharmacological activities. In this paper, the absorption, distribution and metabolism of flavonoids in gaster, gut and liver were introduced. The research of absorption, distribution and metabolism on flavonoids will provide theoretical basis for developing new drugs of flavoniods.

ABSTRACT

Flammulin, an anti-tumor protein, was purified from the aqueous extract of basidiomes of Flammulina Velutipes. Purified flammulin emulsified with Freund's adjuvant was injected subcutaneously into New Zealand white rabbits. After several immune enhancements, these animals were bled and sera were separated. Antiserum against flammulin in Western blots were applied to determine if flammulin be present in the liquid state culture or fruiting body. The result showed that anti-flammulin serum could recognize the aqueous extract of fruiting body in SDS-PAGE gels under the reducing conditions, no flammulin was detected in mycelia of Flammulina Velutipes.
