Objective:To study the therapeutic effect of Liyanling granules on chronic pharyngitis. Methods:The chronic pharyn-gitis rat models were established, and administered orally for 7 days. The influence of Liyanling granules on the pathology of pharyngeal tissue and the contents of PGE2 , IL-1β and TNF-α were observed. The blood was withdrawn to detect the whole blood viscosity and plasma viscosity, and the anti-inflammatory effects were observed in two kinds of rat models:foot pad swelling induced by carrageenin and agar-induced chronic granuloma. Results:Liyanling granule could significantly decrease the levels of PGE2 , IL-1βand TNF-α( P<0. 05 or P<0. 01) and the viscosity of blood and plasma(P<0. 05 or P<0. 01), improve the pathological morphology of rat pharynge-al tissues(P<0. 05 or P<0. 01), inhibit the swelling of foot pad induced by carrageenin and the granuloma induced by agar in rats(P<0. 05 or P<0. 01). Conclusion:Liyanling granules has a certain therapeutic effect on chronic pharyngitis in rats, and the mecha-nism may be related with the inhibition of inflammatory cytokines PGE2 ,IL-1β and TNF-α and the improvement of blood rheology.

Objective To investigate the value of multi-slice spiral CT (MSCT) in diagnosis of colorectal carcinoma. Methods MSCT images of 42 cases of colorectal carcinoma proved by surgery and pathology were retrospectively analyzed. Multiplanar reconstruction (MPR) in all cases, and curved planar reconstruction (CPR), shaded surface display (SSD), CT virtual colonoscopy (CTVC) and Raysum were performed in some of the cases. MSCT findings were analyzed in comparison with operative and pathologic features. Results The detecting rate and quatitative rate of colorectal carcinomas with MSCT were 100%,respectively.The accurate rates were 82.9%(29/35) and 100%(7/7) in detection of invasion of surrounding structures and metastasis in abdominal organs respectively,the sensitivity and specificity for detetion of lymph node metastasis were 71%(22/31) and 100% with MSCT imaging.Conclusion MSCT scan with multiform reconstruction techniques can make definite diagnosis of colorectal carcinoma, which is helpful for treatment plan.

Objective Investigation and analysis of intelligence and psychomotor function in children born after implementingt universal salt iodization(USI). Methods Historical serious illness areas of water iodine below 10μg/L were selected as study sites, water iodine in 50 - 100 μg/L in the historical non-endemic areas were as control points in Henan, 2008. Cluster sampling was used to select children aged 6 - 15 years as observing subjects,IQ were measured with CRT- Man Test(CRT-C2). A "Tianjin Medical psychomotor test battery" (JPB) was carry out to test psychomotor function. Results In IDD regions 230 children were surveyed post-USI and 1284 children preUSI. The IQs post and pre USI were 99.3 and 99.9, respectively, and the proportion of IQ ≤69 were 2.17%(6/230) and 2.80%(36/1284), respectively. In non-IDD regions 650 children were surveyed post-USI and 2079children pre-USI. The IQs post and pre USI were 95.3 and 93.8, respectively, and the proportion of IQ ≤ 69 were 2.31%(15/650) and 3.37%(70/2079), respectively. In IDD regions, the abnormal rate of T scores and damage index post USI were 3.6%(2/56), 5.3%(3/56), respectively, significantly lower than pre USI [18.1%(29/160),18.1%(29/160), x2 = 7.54, 6.86, all P ＜ 0.01]. Conclusions USI could increase the IQs of children and decrease the positive rate of JPB, and significantly improve the quality of whole nation and persistently eliminating IDD.

For the purpose of expanding the analysis scope of medicines,a RPHPLC assay procedure has been established for quantitative analysis of indomethacin in human plasma.Analytical column was YWG C18(?4 6 mm?200mm).Mobile phase was methanol water acetic acid solution(67∶33∶0 1)(v/v) and wavelength of detector was 254nm.The linear relationship,precision,method of extraction and recovery were comparatively investigated by standard blank human plasma spiked with indomethacin.Indomethacin leved in the blood of the healthy volunteers was detected by using this method.The linear range of the method was 0 1～5 0?g?ml -1 .The calibration curve was linear (?=0 9995). The detection limit was 0 02?g?ml -1 (S/N≥3) and the recovery of indomethacin in human blood was between 97 5%～104 2%. Intra and inter day prccision of the mothod were(1 1?0 2)%(n=4) and(2 7?0 6)%(n=4)respectively.The CV% were no more than 3 0% (n=4).The method shows a high sensitivity,precision,fast and excellent selectivity.Thus it is suitable for investigation of the indomethacin in human blood and its toxicological analysis as well as the pharmacokinetic study.

ObjectiveTo observe the effect of community-based rehabilitation (CBR) on older stroke patients in ability of activities of daily living (ADL).Methods50 older stroke patients were randomly divided into the rehabilitation group and control group. The rehabilitation group was treated with motor function exercise and ADL training, while the control group only took medicine. Two groups were evaluated with Barthel index before and after treatment. ResultsScores of Barthel index on the rehabilitation group were higher than that on the control group after treatment, and there was a significantly difference between two groups (P<0.01). Conclusions CBR has the significant effect on improving ADL in older stroke patients.

Drug therapy is one of the efficient methods for prostate cancer treatment. However, drug resistance greatly hindered the treatment of prostate cancer patients. Herein, the mechanisms of drug resistance in prostate cancer have been exhaustively reviewed, and that can provide an alternative strategy and new targets for anti-prostate cancer therapy.

Objective:To study the effect of portal vein occlusion on intestinal mucosal barrier in rats and the protection of ulinastatin to the injury,to present the experimental data for the clinical surgery.Methods:70 Sprague-Dawley rats were randomly divided into controlled group (n=10),operation group (n=30) and operation+medication group (n=30).The portal vein were occlused 40 min in the operation groups and operation+medication groups.2ml blood from portal vein,lymph nodes around appendix,1cm small intestine wall were taken for endotoxin levels,bacterial translocation and pathiology examinations in the all rats 280 mins after operation.The mocusal barrier and microscopic structure of intestine were observed.Results:Compared between the control group and the operation group,endotoxin levels,bacterial translocation rates rise greatly and gut structure change obviously in the latter.Compared between the operation group and operation+medication group,the former changes is also obvious.Conclusion:The occlusion of portal vein can leads the decrease of intestine mocusal barrier and the increase of its permeability.Ulinastatin has a good protective effect on the damages above.

Background and purpose:Tumor microenvironment plays an important role in the introduction of foreign factors that mediate tumor acquired resistance. The antitumor effects of many chemotherapeutic agents depend on the level of oxygen pressure (pO2) in tumor microenvironment. This study aimed to evaluate electron paramagnetic reso-nance (EPR)-based monitoring on an oxygen-enriched tumor microenvironment to increase chemotherapeutic sensitivity. Methods:MCF-7 cells were used to establish human breast cancer in nude mice. EPR was used to directly measure pO2 levelin vivo. Tumor tissues were collected, and mitochondrial activity was assayed on the basis of the kinetics of enzyme-catalyzed reactions. A laser Doppler monitor was used to detect regional blood flow. Tumor apoptotic rate was analyzed by flow cytometry.Results:The tumor volume decreased more evidently in the chemotherapy group with oxy-gen-enriched environment than that in the conventional chemotherapy group after the treatment was administered (P<0.01). After chemotherapy was completed, the apoptotic rate of tumor cells was significantly higher in the chemotherapy group with oxygen-enriched environment than that in the conventional chemotherapy group (P<0.001). This study examined the mechanism ofpO2 changes in tumor microenvironment: This was related to the change of the balance between the oxygen consumption and the regional blood flow in the tumor tissues after chemotherapy.Conclusion:Based on the characteristics ofpO2 changes in the tumor microenvironment after chemotherapy was completed, the selection of chemotherapy mode forthe treatment inpO2 peak time window improves the sensitivity of chemotherapy, which provides a new idea for individual-ized chemotherapy in clinical applications.
