To analyze the composition regularity of prescriptions containing Scutellaria baicalensis in Drug Standard of Ministry of Public Health of the Peoples Republic of China--Chinese Patent Medicines and Preparations on the basis of the traditional Chinese medicine inheritance support system (TCMISS), in order to provide reference for new drug R&D. the platform's software V2.0 was applied to establish a database of prescriptions containing S. baicalensis. The software's statistical statement module, association rules and improved mutual information method and other data mining technologies were adopted to analyze commonly used drugs, combination rules and core combination of S. baicalensis prescriptions. Having analyzed 477 prescriptions containing S. baicalensis, the researchers summarized 45 most commonly used drug combinations, whose ingredients mostly had functions of heat-clearing and damp-drying, purging fire for removing toxin and hemostasis. Drugs adopted in core combinations were relatively concentrated and selected according to definite composition methods. There were 23 diseases that S. baicalensis were most frequently applied in the treatment. Having compared three highly frequent diseases--cold, cough and dizziness, the researchers concluded that S. baicalensis could show different therapeutic effects through different combination ratios. Therefore, TCMISS (V2.0) is an important tool in analyzing the composition regularity of traditional Chinese medicines. The longitudinal and parallel comparison method is an effective method for studying the clinical composition regularity of S. baicalensis, while providing reference for new drug R&D.

Objective To investigate the features and significance of pathologic changes in apoptosis of small bowel allograft during acute rejection in rats. Methods All 24 recipients were equally divided into four groups ; group A: nonoperative control; group B: allograft ; group C: isograft, group D: treatment control. The graft samples were harvested on day 3, 5, 7, 10 after transplantation, and subjected to histologic examination . Mucosal thickness, villous height and crypt depth were measured, and apoptotic cells of intestinal mucosa of grafts on day 3,5 and 7 after transplantation were examined. Results The mucosal structure was normal in group A; The degree of the inflammatory infiltrated cells ,intestinal mucosa cell apoptosis and structural injury of mucosa in group B were significantly severe compared with groups C and D. As the post-transplanted time increased, the number of musocal apoptotic cells and the degree of mucosal structural injury were significantly increased. The degree of mucosal structural injury in group C was milder than in group B. A few infiltrated cells and mild edema of mucosa occurred in group D , but no mucosal structural injury was found. Conclusions Inflammatory cell infiltration, mucosal epithelial cell apoptosis and mucosal structural damage are the main pathologic features of small bowel allograft during acute rejection. Dynamic observation of the pathologic changes and cell apoptosis of small bowel graft is of certain value in the diagnosis of acute rejection of small bowel graft and in assessment of the degree of small bowel injury.

Objective To evaluate the clinical efficacy of oral Sarpogrelate hydrochloride in the treatment of chronic arterial ischemia of the lower extremities.Methods In this study 892 patients,who suffered from arteriosclerosis (ASO) or thromboangiitis obliterans ( TAO ) or diabetic foot ( DF ),with symptoms of intermittent claudication, sensation of cold, pain, ulcer, and without a history of vasotransplantation or bypass grafting or interventional therapy, were treated by taking Sarpogrelate hydrochloride tablets 100 mg tid for consecutive 8 weeks.The improvement rate of concomitant symptoms and the total effective rate of ASO, TAO, DF were evaluated.Drug adverse reaction were recorded.Results The improvement rate of intermittent claudication,sensation of cold,pain and ulcer were 96.9％,97.1％,89.0％ and 86.9％ respectively.The total effective rate for ASO,TAO,DF was 83.5％.A total of 81 cases (9.1％) reported mild side effects,including 7 patients with mild rash after 2- 5 days' medication,21 patients with mild nausea and 53 patients with stomach discomfort after 1 - 2 days' medication.Symptoms were managed conservatively without discontinuing taking sarpogrelate hydrochloride.Conclusions Sarpogrelate hydrochloride oral is a safe and effective therapy for chronic arterial ischemia diseases of the lower extremities.

In this study, nattokinase gene was amplified by PCR using bacillus subtilis chromosomal DNA as template and cloned into expressed vector pBV220. After transforming recombinant plasmid into E.coli HB101, the recombinant strain was yielded. It was proved that expression products was secretive and expression protein was 12% of total cell protein by SDS-PAGE. Optimum culture time and inducing time was determined as 6h and 5h respectively. The plasmid stability studies showed that recombinant plasmid has excellent segregational stability but the structural stability was not good in the host cell.

OBJECTIVETo explore clinical outcomes and advantages of anterior small-incision focus debridement with posterior internal fixation through muscle spa ring in treating patients with lumbar spinal tuberculosis.

METHODSFrom February 2010 to February 2014, totally 82 patients with lumbar spinal tuberculosis were treated by posterior individual fixation with small-incision focus debridement,including 50 males and 32 females with an average of 50.5 years old. All patients were divided into two groups according to different procedures. Forty-nine patients in group A were treated with anterior small-incision focus debridement with posterior internal fixation through muscle spa ring at stage I ; and 33 patients in group B were treated with focus debridement with posterior internal fixation by extraperitoneal approach at stage I . Postoperative mechanical ventilation time, preoperative and postoperative Cobb angle, visual analogue scale (VAS), erythrocyte sedimentation rate (ESR) and Frankel grading were observed and compared. Postoperative complications, stability of internal fixation and bone union were compared.

RESULTSAll patients were followed-up from 15 to 36 months with an average of 23.7 months. Psoas abscess of three patients in group A and 1 patient in group B on the opposite side increased and were healed by the secondary apocenosis. The other 78 cases were healed at stage I, and no sinus tract formation, incisional hernia, leakage of cerebrospinal and occurrence of spinal tuberculosis were occurred. Fracture healing time ranged from 3 to 7 months with an average of 4.6 months. Postoperative mechanical ventilation time and VAS score in group A was better than group B. There were no statistical differences in Cobb angle, ESR and Frankel grading at the final following-up between two groups.

CONCLUSIONAnterior small-incision focus debridement with posterior internal fixation through muscle spa ring in treating patients with lumbar spinal according to degree of damage is a safe and effective method.
