OBJECTIVE： To observe the effect of drug loading， medium composition， transdermal enhancer， lauryl alcohol and azone on percutaneous permeation of oxaprozin gel in vitro.METHODS： Drug permeation test was carried out by using modified Franz-type double compartment diffusion cell and isolated mice skin in vitro as transdermal barrier.RESULTS： Under the condition of an effective area of 5.77cm2， it was found that the result was stable and the reproducibility was well with drug loading more than 1.2g， the receiver solution ethanol to normal saline=7∶ 3(v∶ v);The transdermal enhancing effect of lauryl alcohol was superior to that of azone， the effect of mixed transdermal enhancer 3％ AZ＋ 10％ LA was the best.CONCLUSION： The selection of both the optimum release condition and the best penetration enhancers provided reference for oxaprozin transdermal delivery.The standardization of gel percutaneous test in vitro was discussed preliminarily.

Objective To study the DNA extraction and its typing in cigarette butts. Method Chelex 100 extraction method was used to extract DNA of 170 cigarette butts, STR loci were typed after PCR amplification by Profiler Plus kit. Results 21 cigarette butts from one volunteer have no results, the others were all obtained typing results. The samples which were added a little tobacco have no results. Sometimes DNA in sponge contacted with mouth was typed. The small fragment loci were typed in cigarette butts which had been reserved for six months. Conclusion Cigarette butt can be typed by DNA analysis, which is useful in forensic identification.

In recent years, the problems about the protection of intellectual property rights on the traditional medicine has got attentions around the world. Among them, Thailand explored a set of national legislations to protect the intellectual property right about the traditional medicine knowledge, which is very instructive to the developing countries. On the basis of summing up the Thailand traditional medicine intellectual property protection policy, the thesis proposed ideas on the protection of the traditional medicine in China.

Purpose To investigate the correlation between promoter methylation of RKIP and the clinicopathological features of gastric carcinoma and to analyze the correlation between promoter methylation of RKIP and expression of RKIP. Methods The protein ex-pression and promoter methylation of RKIP were detected in 45 cases of surgically resected gastric carcinoma specimens and 21 cases of corresponding normal tissues using the immunohistchemistry SP method and methylation-specific PCR ( MSP) . Results The positive rate of promoter methylation of RKIP was 48. 89% in gastric carcinoma tissues and 4. 8% in adjacent tissues (P<0. 05). The positive rate of the expression of RKIP protein was 42. 22% in gastric carcinoma tissues and 90. 48% in adjacent tissues (P<0. 05). The pro-tein expression and promoter methylation of RKIP were correlated with the degree of differentiation and lymph node metastasis ( P<0. 05) . Expression of RKIP protein in gastric carcinoma was associated with promoter methylation of RKIP. Conclusions Promoter abnormal methylation of RKIP may be one reason of the deletion of expression of RKIP protein, which correlates with occurrence and development of gastric carcinoma.

Objective To explore the effect of anterior decompression plus posterior intradural release in treatment of old thoracolumbar fractures with paraparesis. Methods A total of 22 patients with old thoracolumbar fractures with paraparesis were admitted to our hospital since January 2004 to Jan-uary 2008. Before admission, all patients were treated with decompression and internal fixation with pos-terior pedicle system, with bony compression to the spinal cord found through CT scanning and intact spi-nal cord found by MRI but without obvious neurofunction recovery. Of all, 20 patients were kept with the original posterior fixation except for two patients that were fixed with Z-plate after removal of posterior hardware. Autologous bone grafts from iliac were utilized in all patients. Intradural release was done 3-6 months after anterior decompression. Results Of all, 19 patients were followed up for 17-49 months (average 28 months). Twenty patients obtained varied recovery of neurofunction after anterior decompres-sion, with ASIA motor scores increasing from average 59.4 points before decompression to 71.3 after de-compression. The followed-up patients won further recovery after secondary posterior intradural release, with ASIA motor scores further increasing to average 80.6 points. Conclusion For patients with old thoracolumbar fractures combined with paraparesis, the release of intradural sear and fibrocompression is also important besides anterior decompression.

We analyze the characteristics of foreign students and the problems in biochemistry teaching process by summarizing the practice of medical biochemistry teaching for undergraduate foreign students in Wenzhou Medical College. After careful thought on these problems,we brought forward some ideas and methods which may be useful to reform the teaching mode and improve the teaching results of medical biochemistry for foreign students.

Aim To study the effect of simvastatin(Sim) on left ventricular remodeling and heart function in rats with myocardial infarction(MI).Methods Myocardial infarction models were successfully induced by ligation of anterior descending coronary artery.24 h later the survivals were randomly divided into 3 groups.① MI group;② 20 mg Sim group(20 mg?kg~(-1)?d~(-1));③ 40 mg Sim group(40 mg?kg~(-1)?d~(-1)).The rats with sham ligation formed sham group.After 8 weeks,hemodynamic parameters,blood serum lipids,the ratio of RV and LV weight to body weight(RVWI,LVWI) were examined.The pathomorphological change and the collagen volume fraction(CVF) were analyzed by PSR dyeing.Results There were no significant differences in values of serum lipids among 4 groups.Compared with sham group,the left ventricular end-diastolic pressure(LVEDP) was increased and left ventricular systolic pressure(LVSP) was depressed significantly in MI group; the RVWI and LVWI and the CVF in border infarcted zone and Ⅰ/Ⅲ ratio were increased in MI group too.Compared with MI group,Sim partially normalized LVSP and LVEDP;abated ventricular weight index;reduced CVF in non-infarction zone in both Sim groups.Conculusion Simvastatin improves LV remodeling and heart function in rats with MI,which is associated with the effect of limiting myocardial hypertrophy and interstitial fibrosis.

Aim To assess the effect of HMG-CoA inhibitors simvastatin on collagen remodeling in rats after myocardial infarction. Methods Myocardial infarction models were induced by ligation of anterior descending coronary artery. 24 hours later the survivals were randomly divided into 3 groups: (1) MI group; (2) 20 mg Sim group(20 mg? kg-1? d-1); (3) 40 mg Sim group(40 mg? kg-1? d-1). Rats with sham ligation formed into Sham group. After 8 weeks, the ratios of LV and RV weight to body weight (RVWI, LVWI) were examined and the collagen content was detected. The type Ⅰ and type Ⅲ collagen volume fraction (CVF) and Ⅰ/Ⅲ ratio in infarcted and non-infarcted zones were examined with PSR dyeing; also the mRNA expressions of type Ⅰ and type Ⅲ collagen in non-infarcted zone (NIZ) were detected with RT-PCR.Results Comparing with Sham group,the RVWI and LVWI in MI group increased significantly. The type Ⅰ CVF and type Ⅲ CVF in NIZ and the Ⅰ/Ⅲ ratio were increased in MI group. The mRNA expressions of type Ⅰ and type Ⅲ collagen in NIZ in MI group were higher than those in Sham group. Comparing with MI group, the RVWI and LVWI in both Sim groups were decreased significantly. The type Ⅰ CVF and type Ⅲ CVF in NIZ and the Ⅰ/Ⅲ ratio were depressed in both Sim groups, and the mRNA expressions of collagens were also lower than those in MI group, but higher than those in Sham group. Conculusion Simvastatin could attenuate the development of myocardial interstitial fibrosis in non-infarction zone to improve myocardial interstitial remodeling in rats after MI.
