OBJECTIVE: To investigate the relationship between syndrome differentiation of traditional Chinese medicine (TCM) and characteristic changes of vascular endothelial function in patients with diabetic arterial occlusion (DAO) of lower extremities. METHODS: Forty patients with DAO were selected as trial group. Twenty patients among them were attributed to blood stasis syndrome (group A1), and the others were attributed to syndrome of pathogenic dampness-heat attacking the lower limb (group A2) according to syndrome differentiation type of TCM. Patients with diabetes (group B), arteriosclerosis obliterans (group C) and healthy people (group D) were observed as the control groups, respectively. There were 20 cases in each group. Endothelium-dependent dilation (EDD) and endothelium-independent dilation (EID) were measured by high resolution ultrasound in the 100 subjects and the changes of vascular tension factors were also studied. RESULTS: The results showed that EDD in group A was reduced significantly as compared with that in the groups B, C and D. The levels of vascular contractile factors such as endothelin-1 (ET-1) and thromboxane B2 (TXB2) in group A were higher than those in the groups B, C and D, while the levels of vascular dilatory factors such as nitric oxide (NO) and 6-keto-prostaglandin F1alpha(6-Keto-PGF1alpha) were declined significantly as compared with those in the groups B and D. Linear correlation analysis showed that EDD was correlated positively with the levels of NO and 6-Keto-PGF1alpha, while the levels of ET-1 and TXB2 had negative correlation with EDD. EDD and EID in group A2 were declined significantly as compared with those in group A1. CONCLUSION: Our findings indicate that endothelial dysfunction may play an important role in the pathogenesis of DAO and may be associated with syndrome differentiation of TCM.

Objective To studied perioperative changes in blood coagulation and the fibrinolytic system in patients undergoing acute aortic disec tion repair analyse the reason and outcome for these changes.Methods Between August 2011 and December 2011,30 patientsk[22 male and 8 female,mean aged (43.0±9.13) years] had undergone open repairs of aortic dissection or aneurysm with DHCA.Indications for surgical intervention were type A sortic dissection in 26 patients and aortic aneurysm in 4 patients.According to the time from clinical onset of the dissection to operation,acute group(less than 7 days,A group) 20 patients; chronic group (more than 30 days and aortic aneurysm,C group) 10 patients.Data were gathered for muhiple preoperative and intraoperative factors including age,sex,diagnosis,aortic dissection type,preoperative ejection fraction,aortic surgery history,surgical intervention type,cardiopulmonary bypass (CPB) time,aortic cross-clamp time,blood transfusion volume (PRBC),mechanic ventilation time,ICU length of stay and hospital length of stay.Platelet (PLT),fibrin degredation product (FDP),D-dimmer,thrombin-antithrombin (TAT),and soluble fibrin monomer complex (SFMC) were assayed before and after operation,as well as 0 h,24 h,48 h,72 h.These valuables were recorded and compared statistically between two groups.Results Preoperative serum level and postoperative peak level of FDP and D-dimmer in group A were significant higher than in gnoup C (P ＜ 0.05)and postopertive serum peak level in group C were significant higher than preoperative level (P ＜ 0.05 ).Preoperative snd postoperative most hours there was significant intergroup difference on the serum levels of SFMC and TAT (P ＜ 0.05 ).Preoperative level of PLT in group A is lower than in group C significantly (P ＜ 0.05 ).The level of PLT in each hour after surgery were much lower than the level before surgery in both group (P ＜0.05 ).In addition,thromhus fonantion in ascending aortic falsc lumen in group A was much moee common than in group C (P ＜0.05 ).There was significant difference on incidence of postoperative complications between two groups (P ＜ 0.05 ).Conclusion Activation of coagulation and fibrinolysis which results from acute aortic dissection and surgical procedure was obscrved before and after surgery to treat acute aortic dissection.There is increasing risk for consumption coagulopathy and thromboembolism during perioperative period.

The aim of the present study, performed on two different groups of volunteers, is to characterize the pharmacokinetics of lisinopril/hydrochlorothiazide combined tablet. After administration of high, medium and low doses of lisinopril/hydrochlorothiazide combined tablets, AUC and C(max) of two compounds both increase significantly with increase of dose. Neither normalized AUC/Dose nor C(max)/Dose has significant difference between every two tested dose groups. The similar results can be observed as for the parameters of t(max). Lisinopril and hydrochlorothiazide are both eliminated with linear characteristics. After repeated administration of lisinopril/hydrochlorothiazide combined tablets, AUC, C(max) and C(min) of lisinopril in the steady state increase. AUC and C(min) increase significantly. As for hydrochlorothiazide, AUC, C(max), C(min), and t(max) also increase in steady state. AUC and C(min) increase significantly. Administered with the test medication, lisinopril has an fluctuation index (FI) value of 2.29 and reaches a relative steady concentration. But hydrochlorothiazide has an FI value of 4.09 with relatively large fluctuating concentrations.

This study was aimed to observe the protection ofZi-Bu Pi-Yin recipe (ZBPYR) on the cortex mitochondrial dysfunction of diabetes-associated cognitive dysfunction rats. SD rats were randomly divided into four groups, which were the control (Con) group, the diabetes (DM) group, the ZBPYR treatment (ZBPYR1) group and the ZBPYR protection (ZBPYR2) group. Morris water maze test was taken to evaluate the learning and memory ability of rats. The transmission electron microscope (TEM) was used to detect the ultrastructure and quantity changes of cortex mitochondria. Western blot was used to detect the expression of Cyto C. The results showed that compared to Con group, the learning and memory ability were decreased in the DM group (P < 0.05); the learning and memory ability of the ZBPYR1 group was improved compared to the DM group (P < 0.05); compared to the DM group, the ZBPYR2 group was significantly improved (P < 0.01). Compared with the Con group, the number of cortex mitochondria in DM group was decreased (P< 0.05), and the structure was disordered, blurred, or even completely destroyed. After ZBPYR intervention, these pathological changes were reduced obviously. And the number of mitochondria in the ZBPYR2 group was increased than that of the DM group (P < 0.05). The expression of Cyto C in cytoplasm of the DM group was significantly higher than that of the Con group (P < 0.01). After ZBPYR intervention, the expression of Cyto C was decreased. It was concluded that ZBPYR regulated the mitochondrial morphology and changes of volume in the cortex, prevented the releasing of Cyto C from mitochondria to cytoplasm, and improved the cognitive function of diabetes rats.

Objective To evaluate the effects of the project of ditching for drain on Oncomelania hupensis snail control and flood prevention security and explore the optimal engineering design plan in Dongting Lake region. Methods A retrospective study was performed on the previous studies about the project of ditching for drain. The reference values of project indices were determined. The outside levee of Nanhu New Distinct of Yueyang City in Dongting Lake region was selected as the study area , and the cross section of marshland perpendicular to the center line of the levee was extracted to research. According to the situa?tions of various water levels,a dynamic simulation was performed on the effect and security of the project of ditching for drain through the software FLAC3D. Results The retrospective study showed that the project would be effective when the relatively subsoil water level decreased by 0.35 m,and the soil water content decreased correspondingly. The dynamic simulation by FLAC3D showed that the minimum safe distances between transverse ditch 1,vertical ditch and levee toe should be 25 m and 13 m respectively. The digging depth of transverse ditch and vertical ditch should be 1.2 m and 1.0 m respectively. If the width of marshland in drought period was less than 500 m,one transverse ditch was efficient. Otherwise,more transverse ditches should be set with the intervals of 300 m. Conclusions The project of ditching for drain is an effective ecological snail elimination method. Optimizing the digging depth of ditches and distances between transverse ditches,vertical ditch and levee toe will en?sure the effects and security of the project.
