1.Mechanical versus manual anastomoses for artery in clinical renal transplantation
Journal of Chongqing Medical University 2007;0(09):-
Objective:This study compares titanium ring-pin stapler and hand-sutures in the end-to-end anastomosis between renal artery and internal iliac artery in clinical kidney transplant. Methods:In 75 renal allograft recipients, the arterial reconstruction were randomly assigned to anastomoses with either 6/0 interrupted nylon sutures(39 patients) or titanium ring-pin stapler(36 cases). Results:Arterial anastomosis with ring-pin stapler was significantly faster(17.8 versus 28.1 min). In 2 cases, a lower pole artery was successfully anastomosed to the epigastric artery with 2 mm ring. All 75 renal arteries were patented without episodes of postoperative bleeding, or need for revision of the anastomosis in both groups. Mechanical anastomosis resulted in slightly but not statistically significantly less artery stenosis during 2-5-year follow-up.Conclusion:Renal artery anastomosis with ring-pin stapler is as safe and effective as hand-suture. The time required for mechanical anastomosis is only about 1/2 that required for suture anastomosis.
2.Effect of penehyclidine hydrochloride combined with mechanical ventilation on inflammation in rats with acute respiratory distress syndrome induced by hydrochloric acid inhalation
Chinese Journal of Integrated Traditional and Western Medicine in Intensive and Critical Care 2014;(1):50-54
Objective To observe the effect of penehyclidine hydrochloride (PHCD) combined with mechanical ventilation on inflammatory response in rats with acute respiratory distress syndrome(ARDS)induced by hydrochloric acid(HCl)inhalation. Methods 32 adult healthy male Sprague-Dawley(SD)rats were randomly divided into four groups:sham operation group,ARDS model group,PHCD group(intraperitoneal injection of 0.5 mg/kg PHCD at 30 minutes before HCl instillation)and mechanical ventilation group〔mechanical ventilation was given after PHCD treatment,ventilator settings were as follows:tidal volume(VT)=4 mL/kg,respiratory rate(RR)= 70 beats/min,the time ratio of inspiration to expiration(I:E)=1:2,fraction of inspired oxygen concentration(FiO2)=0.21〕,8 rats in each group. The rat ARDS model was created by HCl(0.1 mol/L,1.2 mL/kg) intratracheal instillation. After mechanical ventilation for 4 hours,the experiment was stopped. Arterial partial pressure of oxygen(PaO2)was measured,and the oxygenation index as well as lung wet/dry weight ratio(W/D)were calculated respectively. The pathological changes in lung tissues were observed under light microscope,and the pathological score was evaluated. The levels of myeloperoxidase(MPO),interlukin-8(IL-8)and nuclear factor-κB (NF-κB)in homogenate of lung tissues were all measured respectively by enzyme linked immunosorbent assay (ELISA). Results In rats of ARDS model group, there were significant infiltration of inflammatory cells, collapse of extensive pulmonary alveoli and hyaline membrane formation in lung tissues,but the edema in pulmonary mesenchymal tissue and congestion of micro vessels were not obvious. Compared with sham operation group,the lung tissue pathological score(9.88±2.03 vs. 1.38±0.92),lung W/D ratio(7.67±0.96 vs. 4.08±0.65)were significantly increased(both P<0.01),while oxygenation index〔mmHg(1 mmHg=0.133 kPa):213±29 vs. 428±28〕was markedly decreased in model group(P<0.01);and the concentrations of MPO(μg/L:34.18±3.99 vs. 20.92±1.40), IL-8(ng/L:864±53 vs. 583±91)and NF-κB(ng/L:1 229±133 vs. 803±130)in homogenate of lung tissues were significantly higher in model group(all P<0.01). The pathological changes in lung tissues including inflammatory cell infiltration,collapse of alveoli and pulmonary edema,etc. were obviously improved when treated by PHCD or mechanical ventilation and the lung pathological score and W/D ratio were significantly decreased compared with those of model group,oxygenation index in these two groups were both significantly increased,meanwhile, the concentrations of MPO,IL-8 and NF-κB were sharply decreased when compared with those of model group (all P<0.05). The degree of improvement in all above indexes were greater in mechanical ventilation group than those in PHCD group(lung injury score:5.63±1.85 vs. 7.63±1.67,lung W/D ratio:5.35±1.05 vs. 6.46±1.17, oxygenation index:325±57 vs. 272±44,MPO:25.80±3.36 vs. 29.88±3.93,IL-8:736±53 vs. 802±53, NF-κB:984±75 vs. 1 109±118,all P<0.05),however they did not reach the levels of the sham operation group (P<0.05 or P<0.01). Conclusion PHCD can inhibit the inflammatory response in ARDS rats induced by HCl inhalation,thus it may protect the lung tissue from injury induced by HCl,and the protective role of PHCD plus menchanical ventilation is superior to that of PHCD only.

Acta Nutrimenta Sinica 1956;0(02):-
A gas chromatographic method was established for determination of cholesterol. The egg yolk was directly saponified with 1ml 40% potassium hydroxide and 20ml ethylene glycol. The unsaponifiable substances were extracted by diethyl ether and then dried with anhydrous sodium sulfate. The extract (2?l) was injected into the gas chromatograph. The average percentage of recovery was 100.0?2.6%. The precision of the method was good, the coefficient of variation was 1.9%. The mean cholesterol content of egg yolk determined by this method was 1247.1?80.1 mg/100g and agreed with the value reported in literature.
5.HYPOTENSIVE EFFECT AND MECHANISMS OF SOPHOCARPINE
Chinese Pharmacological Bulletin 1986;0(06):-
Sophocarpine ( SC ) , an alkaloid extracted from sophora alope -curoides L. , was found to have a rapid and significant hypotensive action both in anesthetized dogs and in conscious renal hypertensive rats. On superior cervical ganglia and nictitating membrane preparation ,SC 15mg, administered via lingual artery, briefly relaxes the rigid contraction of nictitating membrane caused by continuous stimulation of sympathetic preganglionic fibers. SC 50, 100, 200?g/kg reduced the vascular resistance index 13.1 ?1.6%, 20.5?4.6%, 27.8?4.1% respectively when perfused into the femoral artery .Measurement of the changes of hemodynamics with constant voltage transthoracic admittance plethysmograph in 5 intact anesthetized dogs showed that SC iv 25mg/ kg enhenced the index of myocardial contractility 18% and heart beat index 40%, shortened Q -Y interval 37%.These results suggest that hypotensive action of SC should be realized by both relaxing the peripheral vascular smooth muscules and blocking the transmission of impulse through the sympathetic ganglia.

Chinese Journal of Primary Medicine and Pharmacy 2009;16(5):771-772
Objective To investigate the effect of batroxobin on the plasma levels of endothelin (ET) and calcitonin gene-related peptide(CGRP) in patients with acute cerebral infarction(ACI). Methods 60 patients with ACI were randomly divided into therapy group(n = 30) and control group(n = 30),500 ml of 5% GS plus 1.0g ramme of Troxerutin was intravenously dripped par day and ticlopidine 250mg/day in the control group. Based on the control group therapy,Batroxobin was intravenously dripped with 10U on the 1st day and 5U on the 3rd and 5th day for seven days. The plasma levels of ET and CGRP were detected pre and post treatment by radioimmunoassay. Results Plasma levels of ET and CGRP in batroxobin therapy group post treatment ( 81.25±27.38 ) ; ( 44. 13±13.30) ng/L were significantly different from those pre treatment(109. 83±38.24) ; (24. 73±13.59) ng/L (all P<0. 01 ) ,and were also significantly different from those post treatment in the control group(98.07±30. 39) ; (37.02±12. 41 )ng/L (all P<0. 01 ). Conclusion Batroxobin can accommodate the equilibration between ET and CGRP, and protect brain cell and blood vessel endothelial cell.

Cancer Research and Clinic 2010;22(7):436-439
Target therapy is a major progress in treatment of advanced colorectal cancer. Cetuximab and bevacizumab are the most widely used target agents in colorectal cancer, which target against EGFR and VEGF respectively. The addition of target agent to chemotherapy improve efficacy and prolong survival in the first line setting, as well as in the second line setting. The increased respectability of liver metastases from colorectal cancer is of great importance, k-ras gene mutation is a definite predictor of cetuximab, however, there is no clear predictor for bevacizumab.
