Chinese Journal of Hypertension 2007;0(07):-
Objective To observe the effect of depside salt from Salvia Miltiorrhiza on platelet endothelial nitric oxide synthase(eNOS) activity in health adults.Methods Peripheral venous blood was collected,platelets were isolated with gel-filtration chromatography and incubated with eNOS agonist histamine,eNOS inhibitor L-NAME and different concentrations of depside salt from Salvia Miltiorrhiza(0.1,1,10,100,1000 mg/L) for 30 minutes,then eNOS activity was measured as formation of 3H-L-citrulline from 3H-L-arginine.Results(1)Platelet eNOS activity was significantly inhibited after incubated platelets with L-NAME and increased after incubated with histamine(P

Chinese Journal of General Surgery 2001;0(10):-
Objective To explore the role of apoptosis in the pathogenesis of acute pancreatitis(AP)and to (investigate) the effect of ligustrazin(LGT) on the apoptosis in acute pancreatitis .Methods Experimental animals were divided into three groups randomly: (1) AP group, (2) comparison group,and (3) therapy group. Pathologic score and TUNEL method were used to detect the pathologic mophology of pancreatic tissue and the pancreatic cell apoptosis index in the 3 groups. Results In the early stage of AP,the majority of cells are apototic and the degree of AP is slight.In the late stage of AP,the majority of cells show necrosis,and the degree of AP is severe.The (induction) of cell apoptosis can lessen the pathologic state of AP. Conclusions The degree of pathologic changes in AP can be lessened by the induction of cell apoptosis,but there is a definte time limit.
6.Treatment options of unstable distal radial fractures in elderly patients
Chinese Journal of Geriatrics 2010;29(7):563-565
Objective To study the advantage and disadvantage of different treatments of unstable distal radial fractures in elderly patients. Methods In the period from August 2005 to January 2010, 55 elderly patients with unstable d istal radial fractures were treated with manual diaplasis and external plaster splint fixation, operation and internal plate fixation, or external fixation. Clinical outcomes were evaluated by Gartland-Werley wrist scoring systems and questionnaire of the disabilities of the Arm, Shoulder and Hand (DASH). We used SPSS13.0 software package for statistical analysis. Results Compared with the manual diaplasis group, the operation and internal plate fixation group or external fixation group was better in Gartland-Werley scores, the differences were statistically significant (P<0.05), but there were no differences in DASH scores among the 3 groups. Conclusions The treatment of unstable distal radial fractures in elderly patients should be chosen based on the characteristics of the fractare and patients desire.

Objective To study a simple surgical method for continuous rapid tissue expansion and its clinical application. Methods The operation was accomplished in two-stage procedures. First, expanders were placed in the subcutaneous pocket through interlesional perpendicular short incisions. Continuous expansion by trace syringe pump began from the second day after expander placement. The speed of water injection was set according to patient's algesthesia reaction and vascularity of skin. The second operation was carried out at the third to fifth day after the expansion completed.Results The method was put into clinical practice in 22 cases (16 cases of scar, 2 cases of capillary angioma, and 4 cases of black nevus), and 35 expanders were placed. The speed of water injection was set in 0.2~0.8ml/hr/100ml.The mean time of water injection was 15.3 days. In the process of expansion, all cases were satisfactory except 1 case, in which the expander exposed in the incision. After the second operation, all flaps survived except one showing distal skin necrosis. The result was satisfactory after 3 months to 1 year follow-up. Conclusion The procedure consists of expander placement through interlesional perpendicular short incisions and continuous expansion in advance, which maximally shortens the time of expansion and hospitalization. This expansion method is a simple, safe, reliable, and ideal rapid tissue expansion technique.

Objective Previously, there was an argument on the surgery way of unilateral papillary thyroid microcarcinoma(PTMC).The purpose of this study was to investigate the predictive factors of occult thyroid carcinoma in unilateral thyroid papillary microcarcinoma, and to compare the surgical methods of unilateral thyroid papillary microcarcinoma.Methods We retrospective analyzed 327 cases of unilateral PTMC patients confirmed by preoperative color Doppler ultrasound examination from January 2014 to January 2016 in Department of Breast Surgery, First Affiliated Hospital of Harbin Medical University.According to the presence of occult cancer, patients were divided into unilateral glandular foci (n=278) and bilateral glandular foci(n=49);according to whether carry out the prevention of central lymph node dissection, patients were divided into lymph node dissection(n=117) and without lymph node dissection(n=210) to further analyze the predictive factors of contralateral gland occult cancer and postoperative complications of preventive central lymph node dissection.Results 55 cases had central lymph node metastasis in 117 cases with lymph node dissection, the metastasis rate was 47.0%.The multiple foci in the ipsilateral gland is a risk factor for the presence of occult foci in the contralateral gland (OR=4.924, 95%CI: 1.605~15.107).There was no significant difference in postoperative complications between lymph node dissection and without lymph node dissection(P>0.05).Conclusion multiple foci in the unilateral thyroid papillary thyroid microcarcinoma can help us to predict the contralateral gland occult cancer, and the central lymph node metastasis rate is higher, therefore, for the unilateral glands of multiple tumors in the papillary thyroid microcarcinoma, we recommended the total thyroidectomy+prophylactic central lymph node dissection surgery way.
