China Pharmacy 2001;12(6):331-333
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.

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.

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.

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.

Objective To investigate the expressions of CXCR4 in Barrett esophagus (BE), esophageal adenocarcinoma (EADC) and esophageal squamous cell carcinoma (ESCC), and its relationship with pathology, clinical staging and lymph node metastasis. Methods The expressions of CXCR4 in 56 cases of normal esophageal mucosa, 80 BE (including 22 BE with multifocal dysplasia), 25 EADC and 48 ESCC were examined with immunohistochemical method. Results CXCR4 was expressed in most samples of BE (80. 8% ), EADC (68. 0% ) and ESCC (78.4%) without significant difference ( P > 0. 05 ), which was significantly higher than that in normal esophageal mucosa (39. 3%, P <0. 01 ). The level of CXCR4 expression in BE, EADC or ESCC were not related with gender, age, or location of the foci ( P > 0. 05). There was no significant difference in CXCR4 expression between BE without dysplasia or BE with multifocal dysplasia ( P > 0. 05 ). CXCR4 expression level in well-differentiated EADC was significantly higher than that of mild or poorly differentiated (P < 0. 05 ). CXCR4 expression level was higher in EADC with lymph node metastasis than those without ( P < 0. 05 ). CXCR4 level in ESCC with TNM staging grades Ⅲ -Ⅳ was higher than that of grades Ⅰ - Ⅱ, and this variable was also higher in cases with lymph node metastasis than those without (P < 0. 05), so was the case of well and poorly differentiated ESCC (P < 0. 01 ). Conclusion Increased expression level of CXCR4 may be a common feature of EADC and ESCC, which is irrelevant to pathological types. CXCR4 level rises at the stage of BE, which is associated with the degree of tumor differentiation, lymph node metastasis and TNM staging. CXCR4 expression is of guiding significance in the diagnosis of BE, EADC and ESCC, and is the potential drug target.
