Objective To explore the effect of TLR2 on collagen Ⅰ(colⅠ) in adipose tissue of high-fat-diet induced obese mice.Methods Male C57bl/6J mice and TLR2 knockout mice were divided into groups according to high fat diet or normal chow.Total collagen, TLR2, colⅠ, MMP1, MMP2, TIMP1, colⅠα1 mRNA and colⅠα2 mRNA in adipose tissue were measured at the end of the experiments.Results Total collagen, TLR2, colⅠ, MMP2, TIMP1, colⅠα1 mRNA, and colⅠα2 mRNA in adipose tissue increased while MMP1 in adipose tissue decreased in mice with high fat diet.Decreased levels of total collagen, colⅠ, MMP2, TIMP1, colⅠα1 mRNA and colⅠα2 mRNA in adipose tissue were detected in TLR2 gene knockout mice with high fat diet.However, there was an increased level of MMP1 in TLR2 gene knockout mice with high fat diet.Conclusion In high-fat-diet induced obese mice, deposition of colⅠ in adipose tissue seems to be alleviated by TLR2 gene knockout via MMP1 and TIMP1.

Objective To optimize the processing method of Codonopsis pilozula prepared product by the factorial design and response surface methodology. Method In the two different optimizing processing, methods were optimized respectively on basis of preplanned experiment design and the percentage of extracts were also determined respectively. Drying temperature and time, bran parching temperature and time respectively as independent variable, their OD value as dependent variable, multiple regression equation was obtained and binomial equation was simulated as well. Results The r2 of Codonopsis pilozula dried product and Codonopsis pilozula parched product were respectively 0.976 4 and 0.987 9, meanwhile their optimized processing methods were drying temperature 80 ℃, drying time 2 hours and parching temperature 250 ℃, parching time 1 minute. Conclusion The effect of independent variable to dependent variable can be analyzed on three-dimensional chart with the factorial design and response surface methodology, consequently it will help to optimize processing method of prepared product.

Objective To establish a suitable formulation for the dispersible tablets of breviscapinum. Methods The preparative process was scanned out by single factor test and orthogonal design. A comprehensive scoring analysis was performed with disintegrating time and rigidity as the indexes. Results The demonstration for the dispersible tablets from the optimized formulation,being totally disintegrated within three minutes and sifted through the sieve in size of the 2nd,show better dissolubility in-vitro in comparison with the common tablets and their quality meets with the requirement for the dispersible in Phamarcopoeia of the People's Republic of China. Conclusion The formulation screened out for the dispersible tablets of breviscapinum is suitable for the production on a large scale.

OBJECTIVE: To evaluate the diagnostic value of multi-slice spiral CT (MSCT) for plasma cell mastitis. METHODS: Radiographs of MSCT for forty-six patients with plasma cell mastitis diagnosed by pathological examination were reviewed. RESULTS: The findings of MSCT of plasma cell mastitis could be divided into four types, including the inflammation type, the abscess type, the sinus and fistula type, and the mixed type, and each type had its radiographic characteristics. CONCLUSION: MSCT is helpful for diagnosing plasma cell mastitis and should be used as an examination of first choice for the patients.

Objective To evaluate the clinical application of the fistulography of multi-slice spiral CT(MSCT)in the diagnosis of anal fistula.Methods A total of 28 patients who were verified operatively of fistula in ano underwent preoperative fistulography of MSCT.The multi-planar reformation(MPR)and surface shadow display(SSD)images were generated and analyzed retrorespectively.Results There were 8 cases with perianal abscess and 20 cases with anal fistula in 28 patients.Complex fistula was diagnosed in 16 cases,and simple inter-sphincteric fistula was found in 4 cases;the inner orificiums of anal fistulas were revealed accurately with MPR images in 18 cases.Conclusion The fistulography of MSCT is valuable for preoperative assessment of anal fistula,in particular for investigation of the inner orificiums of anal fistulas with MPR.

Objective To investigate the hospital mortality of rheumatic heart disease (RHD)and major cause of death. Methods One hundred and thirty patients with RHD prepared to take valve replacement from January 2006 to November 2009 were involved in this study. They were divided into two groups according to all clinical data: death group (10 cases ) and survival group (120 cases ). The clinical data and complications were collected, and the hospital mortality and their causes were analyzed with Logistic regression analysis. Results Univariate analysis: total bilirubin and indirect bilirubin levels in death group [(30.31 ± 19.10), (22.38 ± 17.34) μmol/L] were significantly higher than those in survival group [(19.47 ± 8.61),(12.92 ± 7.30) μmol/L] (P ＜ 0.01). The incidence of postoperative complications,history of cerebral infarction and cardiovascular complications in death group were significantly higher than those in survival group (P ＜0.01). The Logistic regression analysis showed that the postoperative complications was an independent risk factor for hospital mortality (P =0.002). Conclusions RHD with postoperative complications is identified as an independent predictor of hospital mortality. It is very important to enhance the treatment and care during hospitalization.

Wuhan Pu Ai Hospital implemented the pharmaceutical direct supply mode since October 2006 as an experiment.The pilot proved the mode as successful in reducing drug costs proportion,promoting rational use of drugs,and raising business volume of the hospital.Authors also recommend to further efforts in drug supply price supervision mechanism,government subsidy mechanism,direct supply catalogue and drug supply mode among others.Other recommendations include innovation in directly supply mode,hospital internal reform,packaged performance appraisal and incentive mechanism for medical workers,and building a ceiling mechanism for total medical expense control.

According to the correlative analyses on Chinese medicine essence, dosage forms and quality control level, it expounds the precise concept of Chinese medicine, and its quality advantages and characteristics in this paper, furthermore discusses how to achieve the ideal drugs and Chinese medicine quality precision in expectation. Base on the Chinese medicine essence, using the concept of nature medicine and its drug system to construct Chinese medicine effective material basis and its drugs, with the correlative analyses of whole view and reductionism, the problems of uncertainty quality of original natural medicinal resources and preparations may well be solved, and further with the macroscopic to microcosmic construction of drug system, the precision in expectations of Chinese medicine quality and higher production lever may well be achieved.

Purpose To investigate the expression of estrogen receptor ( ER) and progesterone receptor ( PR) in endometrial tissue in patients with intrauterine adhesion ( IUA) and their clinical significance. Methods Two experimental methods, immunohistochemical MaxVision two step method and real-time fluorescencequantitative PCR ( qRT-PCR) , were used for detection of ER and PR in endome-trial tissue both in group IUA ( study group) and non IUA group ( control group) . Results MaxVision immunohistochemical method showed that ER protein expression in the study group (3. 52 ± 0. 71) was significantly higher than that (2. 75 ± 1. 00) in the control group (P=0. 01), ER mRNA expression by qRT-PCR was also significantly higher in the study group (1. 59 ± 0. 26) than that (1. 00 ± 0. 19) in the control group (P=0. 00). The immunohistochemical detection of showed that PR protein expression in the study group (3.26 ±0.70) had no significant different from that (3.58 ±0.28) in the control group (P=0.12), qRT-PCR also showed that ER mRNA in the study group (1.15 ±0.21) had no significantly different from that (1.00 ±0.31) in the control group (P=0. 21 ) . Immunohistochemical expression of ER and PR proteins showed a significant difference between the endometrial glands and en-dometrial stroma (χ2 =5. 797, P=0. 016,χ2 =4. 857, P=0. 027). Conclusion The expression of ER in endometrial tissue in the study group is higher than that in the control group, but the expression of PR has no different between the two groups, ER and PR pro-teins expression are higher in endometrial glands than that in endometrial stroma. These provide a theoretical reference for clinical use of estrogen and progesterone to IUA patients.
