This study was aimed to observe the effect of Danzhi Jiangtang Capsule ( DJC ) on expression of solu-ble thrombomodulin ( sTM ) and soluble endothelial cell protein C receptor ( sEPCR ) in experimental rats of type 2 diabetes mellitus (T2DM). This study also explored possible mechanisms of Yiqi Yangyin Huoxue method on vascular endothelial tissue and discussed mechanisms of prevention and management of T2DM vascular lesions . A total of 60 male Sprague-Dawley ( SD ) rats were fed for one week and then randomly divided into the nor-mal control group ( group N , n = 12 , rats were fed with routine food ) and diabetes mellitus group ( n = 48 , rats were fed with high-fat diet). After 4 weeks, rats in the diabetes mellitus group were injected with strepto-zotocin ( STZ ) to induce T2DM . According to the blood glucose level , rats were divided into three groups , wh ich were the model group (group M), pioglitazone (group P), and pioglitazone combined with DJC (group D). Group P was treated with pioglitazone (10 mg?kg-1?d-1), group D was given pioglitazone (10 mg?kg-1?d-1) and DJC ( 0 . 47 g?kg-1?d-1 ) . The group N and group M were treated with sodium chloride ( 5 mL?kg -1?d-1 ) . After four-week drug administration , the levels of sTM , sEPCR , PT , APTT and FIB in each group were tested . The results showed that compared with the control group , the levels of sTM , sEPCR and FIB in group M , group P and group D were significantly increased ( P < 0 . 05 ) , and the levels of PT and APTT were obviously reduced ( P < 0 . 05 ) . Compared with group P , the levels of sTM , sEPCR , FIB of group D were significantly reduced ( P< 0 . 01 ) , and the level of APTT was significantly increased ( P < 0 . 05 ) . However , there was no significant dif-ference in the increasing of PT. It was concluded that the Yiqi Yangyin Huoxue method can reduce the levels of sTM and sEPCR , and effectively improve coagulation . The possible mechanisms of protective effect on the vascular endothelium can be from reducing levels of sTM and sEPCR in order to enhance the activity of anti-coagulation and fibrinolysis , regulate the function of blood coagulation to improve hypercoagulable state .

Objective Analyzing NNT epidemiological characteristics and the influeutial factors in Guangdong province from 2001 to 2005 in order to formulate the strategies for elimination NNT.Methods To make descriptive study on the data collected from NNT surveillance system. Results 2832 cases were concentrated in the Pearl River Delta and the west of Guangdong.About 72.04% NNT cases occurred in the migrant children.Through analyzing the data of the year of 2004 and 2005,73.81% of migrant NNT cases occurred in the Pearl River Delta.The cases happened in the Pearl River Delta accounted for 90.18% of whole cases.Most of local cases occurred in the west of Guangdong,which accounted for 39.04% of local cases.The cases occurred all around the year.A seasonal peak of NNT was found from June to August.Most of the onset of disease were during 2～10 days after birth.There were a higher ratio of reported male cases to the female.The ratio was 2.08∶1.Most of the NNT cases were happened to the infants who delivered at home and most of the midmives who were responsible for delivery lacked of training.99.75% mothers did not kown or administe the tetanus toxoid vaccine. Conclusion The elimination of neonatal tetanus is a difficult task in Guangdong province.Publicity to the mass should be strenghtened.The cooperation between sectors should be conducted for NNT eliminodion.

[Objective]To investigate the pathogenesis of osteoarthritis by increasing stiffness of subchondral bone to simulate subchondral bone sclerosis to induce the osteoarthritis.[Methods]The proportion between polymethylmethacrylate(PMMA),methylmethacrylate(MMA),hydroxyapatite(HA) and distilled water was adjusted to keep the maximum reaction temperature under 40℃.The composite material PMMA/HA was obtained and compressed on a mechanical material machine to determine its ultimate strength and stiffness,which were compared with those of subchondral bone.The subchondral bone of medial tibial plateau was scraped,where the composite material PMMA /HA was implanted into.Rabbits were sacrificed at 3,6,9 and 12 weeks,respectively.The articular cartilages of the medial tibial plateau were harvested for histological observation.Immunohistochemical analysis was adopted to record the expression and distribution of collagen type Ⅱ and MMP-1 in cartilage at protein level,which were compared with the blank and control groups.Transmission electron microscope was used to examine the ultramicroscopic changes of chondrocytes in blank and 6,12-week-postsurgery groups.[Results]With the time going,the experimental groups gradually presented degeneration,and had increased histological Mankin score.TEM demonstrated degenerative changes of chondrocytes.Collagen type Ⅱ expressed mainly in transition zone and upper deep zone,and MMP-1 expressed predominantly in the superficial and upper intermediate layers of cartilage.Both expressions steadily increased with time passing.[Conclusion]The increased stiffness of subchondral bone induced osteoarthritis in rabbits,which suggests that subcondral bone sclerosis may induce cartilage damage,and that subcondral bone sclerosis is one of the initial pathogenesis of osteoarthritis.

AIM: The phagocytotic function and morphological changes of pulmonary alveolar macrophages (AM) of rat in high glucose or high glucose and high insulin conditions were studied. METHODS: AM were harvested from Wistar rats by bronchoalveolar lavage and were activated by Bacille Calmette - Guerin (BCG), interferon a - 2b (IFNa - 2b)or BCG and IFNa - 2b. The adherent rate, nitroblue retrazolium (NBT). reduction function and the concentrations of NO and TNF-a in culture rat AM were evaluated. The ultrastructure of AM was Observed by using transmission elects microscopy and scanning electron microscopy. RESULTS: In high glucose or high glucose glucose and high insulin conditions, the adherence of AM postponed(P＜ 0.01 ), NBT reduction of AM significantly decreased(P＜0.01); the volume of NO and TNF-a produced by AM after stimulation with BCG and IFNa-2b + BCG was significantly lower in high glucose groups than in the controls (P ＜ 0.01); their surface pseudopodia was reduced and shortened and the numbers of Golgi apparatus and rough endoplasmic reticulum decreased. CONCLUSIONS:The impaired phagocytotic function and ultrastructure of activated rat AM were much the same regardless of high glucose or high glucose and high insulin level in a short time. Diabetic subjects were predisposed to infection of the lung, which was frequently recurrent or even fatal.

Objective To investigate the risk factors of postoperative complications of delayed hemorrhage,perforation and digestive tract stenosis after endoscopic submucosal dissection (ESD).Methods The complete data of 793 patients with digestive tract disease who underwent the endoscopic submucosal dissection in the Department of Digestive Surgery in our hospital from January 2011 to December 2014 were retrospectively analyzed.All of the patients were divided into delayed hemorrhage group (n =67) and nonbleeding group (n =726);perforation group (n =47) and non-perforation group (n =746);and digestive tract stenosis group (n =38) and non-stenosis group (n =755).The clinical basic data,lesion related data,and operation related data were independent risk factor and analyzed by single factor analysis and Logistic multiple factor regression analysis.Results The incidence of delayed bleeding,perforation and stenosis in patients with ESD were 8.45％,5.93％,and 4.79％,respectively.The results of single factor analysis:the risk factors for delayed bleeding were long-term use of anticoagulant drugs,gastric sinus disease,lesion diameter,and lesion excision (P ＜ 0.05).The risk factors for postoperative perforation were the diameter of the lesion and the time of operation (P ＜ 0.05).The risk factors of digestive tract stenosis were the esophageal lesions,the diameter of the lesion,and the depth of the lesion to the intrinsic muscle layer (P ＜ 0.05).The results of multi factor Logistic regression analysis:the risk ranking of risk factors for delayed bleeding was gastric antrum occurrence lesion ＞ lesions graded resection ＞ long-term use of anticoagulants ＞ lesion diameter (≥5 mm).The risk ranking of risk factors for perforation was operation time (≥90 mm) ＞ lesion diameter (≥5 mm).The risk ranking of risk factors for digestive tract stenosis was esophageal lesion ＞ lesion diameter (≥ 5 mm) ＞ lesions depth to the muscularis propria.Conclusions For long-term anticoagulation,gastric antrum and fractional resection lesions of patients should pay attention to delayed bleeding.Patients with long operation time are easy to cause postoperative perforation.For long-term anticoagulation,gastric antrum and fractional resection lesions of patients should pay attention to delayed bleeding.
