To research the structure-activity relationship (SAR) of glycinamide-bearing compounds that used as inhibitors of dipeptidyl peptidase IV (DPP-IV), P32/98 and compound A were chosen as the leading compounds, heterocycles containing nitrogen atom were introduced to form amide, and different residues on a-position of carbonyl were designed. The nineteen designed compounds were synthesized by a simple route and were evaluated as inhibitors of DPP-IV. All of the structures were characterized by 1H NMR and HRMS. The preliminary SAR result was obtained.

Objective To compare the application,safety and theraputic effect of local resection of early rectal tumours by transanal endoscopic microsurgery(TEM) and the conventional transanal excision(TAE).Methods The data of seventy-six patients who were treated by conventional transanal excision from January 2003 to July 2006 and fifty-three patients who were treated by transanal endoscopic microsurgery from September 2006 to February 2010 in Ruijin Hospital Affiliated to Shanghai Jiao Tong University School of Medicine were reviewed.Results Age,sex,tumour size,blood loss,postoperative hospital stay were similar in the two groups(P＞0.05).The median distance from the anal verge was significantly higher in the TEM group ( TEM/TAE =7.0/5.0 cm,P ＜ 0.01 ).The operation time was significantly longer in the TEM group (TEM/TAE =70.00/30.00 min,P ＜ 0.01 ).There was no operation-related mortality in both groups (P ＞ 0.05 ).Two patients in the TEM group developed postoperative haemorrhage,and one patient developed pulmonary infection and retention of urine respectively.There were two secondary haemorrhage cases in the TAE group.On median follow-up of 30 months,there was 7.8％ recurrence rate in the TEM group,compared with 23.2％ the in TAE group.Conclusions Transanal endoscopic microsurgery is a safe and effective mininally invasive surgical technique for the treatment of early rectal neoplasm.It has broader indication,and better theraputic effect than the conventional transanal excision.

Objective To elucidate the evaluation of therapeutic effects and surgical treatments of 45 cases of inflammatory bowel disease. Methods Clinical data of 45 cases with inflammatory bowel disease by surgical treatment in recent 6 years were retrospectively analyzed. Results Patients received emergency operation in 16 cases, Crohn' s disease in 9 cases, Ulcerative Colitis( UC) in 7 cases. Among 13 cases of Crohn' s disease, partial enterectomy occured in 6 cases, partial enterectomy and colectomy and anastomosis in 1 patient because of internal fistula, repair of ileal perforation in 1 case, laparoscopic ileocolic resection in 5 cases. Among 32 cases of UC, 25 cases underwent ileal pouch-anal anastomosis operation, 3 cases underwent ileostomy with total colectomy, and 4 cases only underwent ileostomy. Twenty- seven cases were cured by operation, 14 cases were improved and 4 cases died. Conclusion It is the key point to achieve successful operation that the corresponding operative modes for varied manifestations of inflammatory bowel disease should be adopted.

Objective To assess the clinical significance of ankle-brachial index (ABI)in the diagnosis of peripheral arterial disease and its relationship with some interfering factors in type 2 diabetes mellitus. Methods One hundred and ten type 2 diabetes mellitus patients were selected.The systolic blood pressure and blood flow waveform in brachial artery,dorsal artery of foot or posterior tibial artery were surveyed with Doppler flow imaging survey meter ES-1000 SPM.ABI was calculated and the patients were divided into peripheral arterial disease group (group A) and non-peripheral arterial disease group (group B).Clinical data and risk factors were analyzed.Results In 110 patients,there were 20 cases (18.2%) with ABI<0.9.Age,TC,LDL-C,24 hours urinary microalbumin (24hUMA) and the prevalence of coronary heart disease were all higher in group A than those in group B (P＜0.05).LDL-C and the prevalence of coronary heart disease were independent risks variable for peripheral arterial disease. Conclusions ABI can assess objectively peripheral arterial disease in type 2 diabetes mellitus.which offers reliable base to active therapy.Advanced age,hypercholesteremia and hyper 24hUMA are the main factors of peripheral arterial disease.

In order to clarify material basis of effective parts of liangxue tongyu prescription, blood-heat and blood-stasis rat model induced by dry yeast was established. The changes of rectal temperature, blood viscosity and plasma viscosity were used to evaluate the cooling-blood and activating-blood effects of liangxue tongyu prescription and its parts. Compared with the model group, the extract from liangxue tongyu prescription, its volatile oil and n-butanol part could significantly reduce rectal temperature (P<0.01), and also reduce blood viscosity and plasma viscosity to various degrees (P<0.01 or P<0.05). So volatile oil and n-butanol part were primarily identified as effective parts of liangxue tongyu prescription. By using GC-MS with normalization method of area to analyze volatile oil of liangxue tongyu prescription, 70 compounds were identified, accounting for about 92.54%, mainly as β-asarone, paeonol, α-asarone and shyobunone. 42 compounds such as peony glycosides, tannins, and iridoid glycosides were identified by HPLC-MS techniques and standard comparison. The study determined the effective parts of liangxue tongyu prescription and clarified the chemical composition providing the foundation for further studies on material basis of liangxue tongyu prescription.

Objective To evaluate the long-term therapeutic results of intersphincteric resection (ISR) in the treatment of ultra-low rectal cancer.Methods Sixty cases of ultra-low rectal cancer with the inferior border of the tumor within 5 cm to the edge of anus underwent intersphincteric resection (ISR),and the clinical data were analyzed retrospectively.There were 39 males,21 females and their average age was 55 years old (range from 30 to 77 years old).The inferior border of the tumor were from 28 to 50 mm to the edge of anus,averaging 42 mm.Results Sixty patients underwent intersphincteric resection successfully with 3 cases developing anastomotic leakage and 2 cases anastomotic stenosis postoperatively.After a median follow-up period of 49 months (range from 18 to 90 months),local and distant recurrence were observed in 6 and 4 patients respectively.Five-year overall survival rate and disease-free survival rate were 88.3％ and 83.3％ respectively.The mean stool frequency were (3.8 ± 1.3) times in each day based on data from 53 patients,and the stool control function of 73.6％ of all patients was preserved satisfactorily according to Kirwan classification.Conclusions This study indicated that intersphincteric resection might be a candidate technique in the treatment of early stage ultra-low rectal cancer restricted within rectal wall and could achieve satisfactory long-term results in both oncologic and functional respects.

Aim To investigate the effects of dioscin ( Dio) on rat myocardial contractility. Methods Left ventricular contractile function was measured using the Langendorff non-recirculating mode of isolated rat heart perfusion. Effects of low, middle and high concentra-tion of Dio were investigated by measuring left ventricu-lar systolic pressure ( LVSP ) and left ventricular end diastolic pressure ( LVEDP) . Also, peak rates of rise/fall of left ventricular pressure ( ± dp/dtmax ) of isolated rat heart were calculated. Effects of Dio on intracellu-lar free calcium concentration in rat H9 c2 cells were measured by using the confocal microscopy. Mitochon-drial membrane potential was detected with multifunc-tional microplate reader. Results With 0. 1, 1 μmol · L-1 Dio, LVSP were significantly enhanced from (11. 55 ± 0. 52), (10. 53 ± 0. 28) kPa to (13. 08 ± 0. 72), (12. 53 ±0. 64) kPa(P<0. 01); +dp/dtmax were dramatically increased from ( 0. 38 ± 0. 10 ) , (0. 40 ± 0. 07) kPa·ms-1 to (0. 42 ± 0. 11), (0. 43 ± 0. 02) kPa·ms-1(P<0. 05). With the 10μmol· L-1 Dio, LVSP and + dp/dtmax were both decreased from (12. 13 ± 0. 33) kPa and (0. 42 ± 0. 04) kPa· ms-1 to ( 9. 46 ± 0. 77 ) kPa and ( 0. 24 ± 0. 04 ) kPa ·ms-1 (P <0. 01). With 0. 1, 1, 10 μmol·L-1 Dio, the relative fluorescence intensity of intracellular free calcium concentrations was increased significantly from (16. 62 ± 0. 89) to (21. 48 ± 0. 80), (25. 68 ± 0. 69) and (19. 84 ± 0. 66)(P <0. 01)respectively. 0. 1, 1μmol·L-1 Dio showed no significant effects on the mitochondrial membrane potential of rat H9 c2 cells, while with effects of 10 μmol·L-1 Dio, the ra-tio of JC-1 monomer and J-aggregates was changed from (1. 14 ± 0. 03) to (1. 35 ± 0. 06)(P<0. 01), indica-ting a decrease in the mitochondrial membrane poten-tial. Conclusion Low and middle concentrations of Dio show a positive inotropic effect on isolated rat heart, as the LVSP and + dp/dtmax are enhanced, which may concern with the increase of the intracellu-lar concentration of Ca2+. It will not cause the calcium overload while the intracellular concentration of Ca2+ is increased by low and middle concentration of Dio in the myocytes except high concentration of Dio.

Choosing the right solvent and timely use is the basis of rational drug use and the most direct and efficient way to improve the safety of traditional Chinese medicine injections. This study aimed to evaluate the influence of solvent and drug preparation time on Shuanghuanglian injection inducing pseudo-allergic reactions with mouse mode. The two tests were carried out: (1) Comparative experiment between different solvent: Shuanghuanglian injection preparation to the appropriate concentration with 0.9% sodium chloride injection and 5% dextrose injection, mixed with Evans blue, at one time intravenous injected into mice, 30 minutes later, the mouse ears vascular permeability were observed and compared. (2) Comparative experiment among different preparation time: placed 10 min, 2.5 h, 6 h and 24 h after Shuanghuanglian injection were prepared and then to detect the pseudo-allergic reactions in mice using the same methods as in (1). The results showed that there was no significant difference in the pseudo-allergic reactions in mice which induced by the same dose of Shuanghuanglian injection, respectively with 0.9% sodium chloride injection and 5% dextrose injection preparation, and with the extension of preparation time, the degree of pseudo-allergic reactions of Shuanghuanglian injection was gradually severe.
