OBJECTIVETo evaluate the intervention effect of diet, exercise and Jiangtang Bushen Recipe (JBR, a Chinese herbal recipe) in preventing the progress of patients with impaired glucose tolerance (IGT) to diabetes mellitus (DM) type 2.

METHODSFifty-one patients with IGT, with their diagnosis conformed to the diagnosis standard of WHO, 1999, were randomly divided into the control group (n = 26) and the TCM group (n = 25). Patients in the control group attended to the educational course for DM and received dietotherapy and kinetotherapy, and to those in the TCM group, under these treatments, JBR was given additionally. Oral glucose tolerance test (OGTT), body weight index (BWI), levels of blood lipids and fasting insulin of all the patients were examined after 3 months, 6 months and 12 months of treatment. The total observation time was 1 year.

RESULTSExcept the 6 cases out of the 51 patients (11.7%), on whom the observation discontinued, in the control group, as compared with before treatment, levels of fasting insulin and fasting blood glucose after treatment were not changed significantly (P > 0.05), also insignificant difference was shown in levels of total cholesterol (TC) and triglyceride (TG), though the two indexes lowered slightly after treatment (P > 0.05), but significant difference was shown in comparison of OGTT/2 h, blood glucose and BWI (P < 0.05). While in the TCM group, fasting blood glucose was changed insignificantly (P > 0.05), but there was significant difference in comparison of fasting insulin, TC, BWI, OGTT/2 h and plasma glucose levels (P < 0.01) respectively before and after treatment. At the end of the study, the cumulative cases with conversion to diabetes were 3 (13.6%) in the control group, and 1 (4.3%) in the TCM group, chi 2 test showed insignificant difference in comparison of diabetes conversion rate between the two groups (P > 0.05), however, the TCM group showed a better year conversion rate of normal glucose tolerance than that in the control group (chi 2 = 8.31, P < 0.01).

CONCLUSIONTCM intervention is possibly effective in delaying the conversion of IGT to DM type 2, and plays integrative effeciency in impelling IGT patients to health. The favorable education and treatment of DM controlling, including dieto- and kineto-therapy may also be advantageous in IGT intervention, but could not be effective in blocking the advance of IGT.

OBJECTIVETo investigate the mechanism of how curcumin improves pulmonary vascular remodeling associated with chronic pulmonary arterial hypertension.

METHODSThe model of chromic hypoxia hypercapniapulmoary remodeling was made. Twenty-four male rats were randomly divided into 4 groups (n = 6): group I (normoxia control group), group II (hypxia and hypercapnia model group), group II (disodium cromoglycate control group), group IV (curcumin treated group). The last 3 group rats were put in a hypoxia cabin where the concentrate of O2 was 8% - 11% and the concentrate of CO2 was 3% - 5%, for 8 h a day and lasting 4 w in total. Group III rats were intraperitoneally injected with disodium cromoglycate (20 mg/kg) and group IV rats were administrated with curcumin by gavage (150 mg/kg). The morphological changes of pulmonary vessel walls and the ultrastructure of mast cells were observed by the optics microscope and the transmission electron microscope. Mast cells and its degranulation state were measured by toluidine blue staining and immunohistochemistry. Data were expressed as means ± SD (standard deviation) and analyzed with SPSS17.0 software.

RESULTS(1) By optics microscopy observation, the value of WA/TA was significantly higher in II group than other groups (P < 0.05). (2) Electron microscope showed that the endothelial cells of pulmonary arterioles in III and IV group were near to I group and the proliferation of pulmonary arterial media smooth cell layer and collagen fibers in adventitia was much lighter than those in II group. The membrane of mast cells was more intact in I, III, IV group than II group. (3) The number of mast cells, the degranulation rate of master cells and the number of positive tryptase stained cells in II group were significantly more than those in other groups. (P < 0.05).

CONCLUSIONCurcumin may inhibit the remodeling of pulmonary vessel induced by chronic hypoxia hypercapnia by mast cell regulation.

Objective:To evaluate the safety and effectiveness of one-stop hybrid therapy for triple-vessel coronary disease.Methods:Totally 34 patients with triple vessel coronary disease were treated by off-pump coronary artery bypass graft (OPCAB)combined with percutaneous coronary intervention(PCI)from Jan.2011 to Jun.2014.All 34 patients received PCI firstly,46 stents implanted in coronary arteries,and then OPCAB were performed,41 distal anastomosis were completed. Results:The one-stop hybrid procedure was successful in all patients.Selective coronary angiography immediately after one-stop hybrid procedure showed that grafts and stents were unobstructed.There was no death during the operation and perioperative period,no episodes of angina attack,no cardio-cerebrovascular events,no bleeding postoperatively and second exploratory thoracotomy.All patients remained free from angina,cardiac function improved significantly and no patient need medical intervention during the(36 ± 8)months follow-up period.Conclusions:One-stop hybrid cardiac surgery provides a reasonable,feasible,and safe alternative for treating patients with coronary artery triple-vessel lesions,and it has good prognosis.

AIMTo demonstrate the specific killing of folate receptor (FR)-positive tumor cells can be achieved by folate-targeted penicillin-G amidase (PGA) combined with its prodrug substrate N-(phenylacetyl) doxorubicin (DOXP).

METHODSFolic acid was covalently linked to PGA and folate content value was determined by quantitative UV spectrophotometry. The ability of folate conjugated PGA to hydrolyze DOXP was measured by RP-HPLC. Visual demonstration of uptake by FR (+) HeLa and SKOV3 cells was detected by using FITC labeled folate-PGA and a fluorescence microscopy. The cytotoxicity of DOXP towards the cells in the presence or absence of folate-PGA was assayed by using MTT method.

RESULTSThe folate-PGA has a specific activity of 29. 8 U x mg(-1) (protein). FR selectivity was confirmed by fluorescence microscopy. The combination of DOXP prodrug with folate-PGA generated higher cytotoxicity towards the FR (+) cells than free doxorubicin. The IC50 was 0.72 micromol x L(-1) for HeLa cells and 0.75 micromol x L(-1) for SKOV3 cells, respectively. Further, the enhanced cytotoxicity reduced greatly with the addition of free folic acid.

CONCLUSIONFolate conjugated PGA did not significantly compromise PGA catalytic activity and enabled binding prodrug-activating enzyme PGA to folate receptor expressing cells, and increased the sensitivity of the cells to doxorubicin followed by administration of its prodrug substrate.

The presence of large segmental defects of the diaphyseal bone is challenging for orthopedic surgeons. Free vascularized fibular grafting (FVFG) is considered to be a reliable reconstructive procedure. Stress fractures are a common complication following this surgery, and hypertrophy is the main physiological change of the grafted fibula. The exact mechanism of hypertrophy is not completely known. To the best of our knowledge, no studies have examined the possible relationship between stress fractures and hypertrophy. We herein report three cases of patients underwent FVFG. Two of them developed stress fractures and significant hypertrophy, while the remaining patient developed neither stress fractures nor significant hypertrophy. This phenomenon indicates that a relationship may exist between stress fractures and hypertrophy of the grafted fibula, specifically, that the presence of a stress fracture may initiate the process of hypertrophy.

OBJECTIVETo evaluate the clinical outcome of surgical venous thrombectomy and simultaneous stenting in patients with acute, symptomatic iliofemoral deep venous thrombosis (DVT).

METHODSFrom October 2008 to December 2010, a total of 15 patients with acute symptomatic DVT underwent combined surgical venous thrombectomy and endovascular stenting in ipsilateral iliac vein. There were 6 male and 9 female patients, with a mean age of 57.4 years (ranging from 36 to 71 years). All patients underwent Duplex ultrasonography for diagnosis of DVT. The location of thrombosis was femoro-ilio-caval vein in 2 cases, bilateral iliac vein in 1 case and left iliofemoral vein in 12 cases. All patients had leg swelling and 12 cases had severe leg pain. The mean time of symptomatic DVT occurring at operation was 3.3 d. The factors related to DVT were operation in 6 cases, DVT reoccur in 2 cases. Coexist diseases were digestive tract bleeding in 1 case, gastric ulcer in 1 case, hypertension in 3 cases and 1 case had cerebral infarction. The inferior vena cava filter was inserted before thrombectomy, iliac vein compression and residual stenosis were treated with a self-expandable stent after thrombectomy.

RESULTSIntraoperative venography showed severe venous stenosis in all patients including 80% of iliac vein compression syndrome, 18 self-expandable stents were inserted successfully, the procedural successful rate was 100%, the 30-day mortality rate was 0.One case was suffered from hematoma at incision after operation. 3 patients were lost during follow-up. Median follow-up was 10.3 months (ranging from 2 to 26 months). There was no case of re-thrombosis. Leg pain was disappeared in all cases and only 2 patients showed slight leg swelling after excise.

CONCLUSIONCombined surgical thrombectomy and endovascular treatment for patients with acute symptomatic iliofemoral venous thrombosis is an effective and safe technique with low morbidity and good clinical results.
