The new generation cyclooxygenase (COX-2) inhibitor could reduce the gastrointestinal side effect of NSAID drugs, but eventually increase the cardiovascular risk, because its selective inhibition of COX-2 induces the imbalance between PGI2 and TXA2 and the reduction of vasodilatory NO. Under pathological conditions, active oxygen species (O2-*2, etc) were used to induce endo- thelial dysfunction, activate NF-κB to induce expressions of pro-inflammatory cytokines IL-1β and TNF-α, increase ET-1, TXA2 with vasoconstrictor effect, reduce PGI2 and NO with vasodilatory effect, generate further oxidative damage together with NO, and reduce the bioavailability of NO. NO-NSAIDs and NO-Coxibs drugs raised the level of NO by introducing NO-donor (ONO2). NSAIDs drugs enhanced the anti-inflammatory activity of COX-2 and reduced gastrointestinal side effects by inhibiting selectively COX-2. If antioxidant structures with active ingredients of traditional Chinese medicines were introduced to improve the antioxidant activity of NSAIDs, they could scavenge the active oxygen species to protect the normal function of vascular endothelia and enhance the bioavailability of NO, which is conducive to enhance the cardiovascular safety of cyclooxygenase (COX-2) inhibitor.

Objective To explore the clinical curative effect of laparoscopic cholecystectomy (LC) in treatment of patients with acute calculouscholecystitis in acute stage. Methods We retrospectively analysed the data of 1353 patients with acute calculouscholecystitis in acute stage who received laparoscopic cholecystectomy in Dept.of General Surgery, The First Affiliated Hospital of Nanyang Medical College and Dept.of Hepatopancreatobiliary Surgery 3,The 2nd Affiliated Hospital of Kunming Medical University from August 2008 to December 2012. Results In 1353 patients, 1316 patients were performed LC successfully (97.27%) . One patient was found with bile duct injury and was cured after Laparoscopic T tube drainage. Two patients were found with postoperative bile leakage, one of them was found with wing hole effusion after removal of the abdominal cavity drainage tube, and was cured after continuous drainage. The operation time was 26-168 minutes, with an average of 47 minutes, the hospitalization time was 3-15 days, with an average of 7.3 days. No incision infection was found . 37 patients were transferred to laparotomy because of common bile duct injury in 2 cases, unclear gallbladder triangle in 23 cases, difficult operation after decompression result from high gall bladder pressure caused by big calculus incarceration in the gallbladder neck in 3 cases, gallbladder gallstone disease in 2 cases, atrophic and vitrified acute cholecystitis and biliary calculus in 2 cases, gallbladder artery bleeding in 4 cases and severe abdominal cavity adhesion in 1 case. Conclusion For patients with acute calculous cholecystitis in acute stage, LC is asafe, effective, and minimally invasive treatment method with quick recovery and low cost, but the operator must be familiar with the anatomy of Calot triangle,and has skilled LC operation skills.

The high and continuing soaring incidence of diabetes may become a huge obstacle to China's development. The antidiabetic drug development is one way to solve the problem. Animal model is a powerful tool for drug development. This paper compares and analyzes the three kinds of animal models for antidiabetic drug development in replicating principle, methods and characteristic, then summarized the application in the research of traditional Chinese medicine. At the same time, the analysis of the market, application and clinical advantages of hypoglycemic medicine from traditional Chinese medicine, is given in this paper, based on the literature analysis. From the point of the clinic advantage embodiment and new drug development, this paper will provide advisory and assistance support for the anti-diabetic fighting with traditional Chinese medicine.

OBJECTIVEWith functional magnetic resonance imaging (fMRI), cerebral function imaging of acupuncture and sham acupuncture at Taichong (LR 3) in patients with essential hypertension (EH) was observed to analyze central mechanism of Taichong (LR 3) to treat EH.
METHODSEighteen EH patients were divided into a twisting acupuncture group (10 cases) and a sham acupuncture group (8 cases), which were treated with twisting manipulation and sham acu- puncture at right Taichong (LR 3), respectively. The treatments were both given with 30-second manipulation and 30- second interval for totally 5 min. During the acupuncture, fMRI was adopted to scan the cerebral function imaging of EH patients on resting state, and the acquired data were analyzed with SPM2 module in Matlab software.
RESULTSAcupunc- ture at Taichong (LR 3) in EH patients mainly increased opposite-side oxygen consumption, which generally activated left anterior cingulated gyrus (BA 32), left inferior parietal lobule (BA 40), left inferior temporal gyrus (BA 19), left middle temporal gyrus (BA 37) and right anterior central gyrus (BA 6). The activated areas were related to motor, vision and cognition of emotion. Stimulation region of sham acupuncture mainly included right anterior cingulated gyrus (BA 24), left inferior parietal lobule (BA 40) and left inferior frontal gyrus (BA 7).
CONCLUSIONThe central mechanism of Tai- chong (LR 3) on antihypertensive effect and symptom improvement is not in thalamus and medulla that are traditionally believed to control blood pressure. Taichong (LR 3) could activate anterior cingulated gyrus to regulate parasympathetic nerve and lower blood pressure, and through anterior cingulated gyrus, the connection with the surrounding areas is strengthened to improve the cognitive impairment caused by long-term hypertension.
