This study is to investigate the therapeutic effect of syringin on adjuvant arthritis (AA) in rats and its mechanisms. Complete Freund's adjuvant (FCA) was used to induce AA in rats. Secondary paw swelling of AA rats was measured with volume meter. Pain response and polyarthritis index were scored. Meanwhile, splenic lymphocyte proliferation response induced by concanavalin A (ConA) or lipopolysaccharide (LPS) was examined with MTT assay. IL-2 production of splenic lymphocytes and IL-1 beta, TNF-alpha production of peritoneal macrophage (PM phi) were estimated by enzyme linked immunosorbent assay (ELISA). The secondary inflammation of AA rats appeared on the 14th day after injection of FCA. Syringin and tripterygium glycosides (TG) were given by intragastric administration for 16 days from the 14th day. Treatment of AA rats with syringin and TG from the 22th day significantly attenuated the secondary hind paw swelling, as well as relieved the pain response and the polyarthritic symptoms of the whole body as compared with that of the AA model group. The suppressed lymphocyte proliferation and IL-2 production of splenic lymphocytes in AA rats were reversed by treatment with syringin. Meanwhile, syringin remarkably down-regulated IL-1 beta, TNF-alpha productions from PM phi. These results indicate that anti-inflammatory effects of syringin on AA rats are mediated by modulating the immune function of abnormal cells and the balance of cytokines.

Objective To investgate the proper perioperative management of Debakey Ⅰ aortic dissection by new type of three branches aortic arch covered stent graft implantation. Methods A total of 56cases with Debakey Ⅰ aortic dissection were enrolled into the study and operated by new type of three branches aortic arch covered stent graft implantation from July 2009 to August 2010. Results The cardiopulmonary bypass time during the operation was 90. 0 -248.0 min( median time 180. 6 ains) ,aortic cross clamp time was 69. 0 - 180. 0 min(median time 108. 2 mins) ,circulation arrest time was 17.0 -37.0 min ( median time 22. 6mins) ,the time using reathing apparatus was 16.0 -260.0 hours (median time 42. 8 hours),ICU residence time was 3.0 -23. 0 days( median time 6. 6 days). Fifty-four patients got well and were discharged. One patient died of multi-organ failure postoperatively and another died of large area of acute myocardial infarction. After the operation, six cases had acute renal failure, five cases had tracheotomy, three cases had reoperation for hemorrhage,one case had retardant pericardial tamponade, one case suffered from spinal cord injury, one had cerebral hemorrhage, and five cases had refractory arrhythmias. Conclusion The new type of three branches aortic arch covered stent graft simplified the procedures of aortic arch operation and lowered the operative risk in treatment of Debakey Ⅰ aortic dissection. Properly control of blood pressure and pain before surgery, shorten circulatory arrest time, maintain good organ perfusion seem to be the key points to improve the prognosis in patients with aortic dissection.

OBJECTIVE:To provide reference for clinical rational drug use.METHODS:Computer network system(CNS)of clinical rational drug use was constructed by using Hospital Information System(HIS),electronic medical records for both outpatients and inpatients and Prescription automatic screening system(PASS),which was then used for real time monitoring of clinical drug use.RESULTS & CONCLUSION:CNS has become an indispensable means for hospital management and clinical drug use in that it can provide support for the data analysis of clinical rational drug use,improve the level of clinical rational drug use,standardize the medical behavior and imrpove the treatment quality.

Polymalic acid, known as a bioactive material, is completely biodegradable, and has far reaching application potential in medical field. Combined with our own findings, we summarized advances in polymalic acid metabolism, microbial fermentation synthesis, and application research in the medical field. Finally, prospect for further research was addressed.

We present a rare case of dental foreign body from maxillary sinus in a 21-year woman who was hospitalized because of oral cavity and nasal sinus leak for 3 months when doing cheek-bulging action. Admission diagnosis :dental maxillary sinus"foreign body" (left); chronic maxillary sinusitis (left). Computed tomographic scan showed irregular high density shadow in the left maxillary sinus. The "foreign body" was removed via anteri- or prelacrimal recess approach, which was supposed to be the iatrogenic foreign body - alveolar bone.

Aim To study the effect of Echinacoside on immune function and the hepatocyte mitochondrial DNA relative content of experimentally aging model mice. Methods Mice were given sc 10%D-galactose 10 ml?kg-1,once daily for 8 weeks to establish the model of aging mice. Vitamin E group ,and ECH groups were given ig Vitamin E 40 mg?kg-1 and ECH 20,40,60 mg?kg-1,respectively at one time. The interleukin-2(IL-2) and interleukin-6(IL-6) content in peripheral blood was measured by ELISA method.Phagocytosis of peritoneal macrophages was tested by neutral red test. Proliferation and transformation of spleen lymphocytes induced by ConA were determined by MTT method. The mitochondrial DNA relative content of liver cells was measured by the means of SDS alkali decomposition from liver.Results The IL-2 content,phagocytosis of peritoneal macrophages and proliferation of spleen lymphocytes were obviously decreased in the aging model group as compared with those in the normal control group.The IL-6 content and mitochondrial DNA relative content of liver cells were significantly increased. ECH 20,40,60 mg?kg-1 and Vitamin E 40 mg?kg-1 could improve the IL-2 content,phagocytosis of peritoneal macrophages and transformation of spleen lymphocytes,and reduce the IL-6 content and mitochondrial DNA relative content of liver cells. Conclusion ECH can enhance immune function and reduce the mitochondrial DNA relative content of liver cells,which may be one of the mechanisms of anti-aging.

Objective To investigate improvements in the diagnosis and treatment of primary malignant tumor of the duodenum. Methods The clinical data of 54 patients with primary malignant tumor of the duodenum treated during a period of 6 years were analysed retrospectively. Results Tumors located in the first, second, third and fourth parts accounted for 6 cases(11.1%), 44 cases(81.5%), 2 cases(3.7%), and 2 cases(3.7%) respectively; and among them, ampullary tumor accounted for 38 cases(86.4%) of tumor of descending portion of duodenum and 70.4% of the total number of duodenal tumors. The main clinical presentation included jaundice, upper abdominal pain, weight loss, abdominal distention, and gastrointestinal obstruction. Upper abdominal pain, no positive signs and abdominal mass were found in 72.0%, 20.0% and 8.0% respectively on abdominal examination. Preoperative associated cholecystopathy accounted for 37.0%. The accuracy rate of duodenoscopy and ERCP in preoperative diagnosis was 94.4%, and 77.8% respectively. Preoperative diagnostic accuracy rate was 27.8%. Panceaticoduodenectomy was performed in 38 cases, duodenectonmy in 1 case, palliative resection of tumor in 9 cases, and tumor was inoperable in 6 cases. Radical resection rate was 72.2%. The postoperative 3- and 5-year survival rate was 40.6% and 21.9%, respectively. After palliative resection, death occurred from 1month to 24months. Conclusions The tumors in the ampullary region account for the majority of primary malignant tumors of the duodenum and are mainly adenocarcinoma. The symptoms of advanced stage are complicated, and specific signs on abdominal examination are few. Associated cholecystopathy is relatively ferquent and preoperative accurate diagnostic rate is low. The examinations of first choice are duodenoscopy and ERCP, and radical panceaticoduodenectomy can extend survival time.

With the rapid increase of the number of cardiovascular disease patients in China, and the popular trend of cardiovascular disease risk factors is becoming more and more obvious, the control of risk factors for cardiovascular disease has become an important public health problem as well as a great challenge to social and economic development. Recent studies show that resistance training plays a positive impact on the control of risk factors for cardiovascular disease. This article reviewed the related literature in recent years for the resistance training control risk factors of the cardiovascular disease, and stated the precautions and challenges during the process of the implementation of resistance training in order to provide new clues to the research and practice for control the risk factors of cardiovascular disease .
