Objective To compare the changes of serum levels of heme oxygenase‐1(HO‐1) ,C‐reactive protein(CRP) and Chitinase‐3‐1ike protein 1(YKL‐40) in patients with rectal cancer after laparoscopic‐assisted radical operation versus open radical surgery .Methods According the integration and elimination standard ,60 cases of patients with rectal cancer were selected and di‐vided into laparoscopic group (30 cases) and open group (30 cases) ,the concentrations of HO‐1 ,YKL‐40 and CRP in peripheral blood of patients were detected on the first and third postoperative day and preoperative day(P<0 .05) ,and were compared between the two groups .Results The serum levels of HO‐1 ,YKL‐40 and CRP in the laparoscopic group were significantly lower than those in the open group on the first and third postoperative day(P<0 .05) .The serum levels of HO‐1 ,YKL‐40 and CRP were significant‐ly increased after surgery ,and serum levels of HO‐1 and CRP on third postoperative day were significantly increased compared with that on the first postoperative day in the two groups after surgery ,while serum level of YKL‐40 on the third postoperative day was significantly lower than that on the first postoperative day in the two groups after surgery .Conclusion The stress reaction is com‐paratively mild in patients with rectal cancer after laparoscopic assisted radical operation ,and the postoperative period may be shor‐ter in patients treated with laparoscopic assisted radical operation than those treated with open radical surgery .

Objective To investigate the effect of dexmedetomidine on the outcome of rats with acute lung injury following blunt chest trauma.Method Forty male SD rats weighing 250～300 g were randomly (random number)divided into 5 groups(n=8 each),namely,group C(normal),group D(normal plus dexmedetomidine),group T(trauma),group TD(trauma plus dexmedetomidine),group TDY(trauma plus dexmedetomidine plus yohimbine).Au rats were sacrificed by using exsanguination from arteria femoralis 6 hours later.The TNF-α and IL-1β levels in plasma were examined by using ELISA.Lung wet/dry(W/D)weight and the percentage of neutrophil in leucocytes in bronehoalveolar lavage fluid(BALF)of rats were detected.HE staining was performed to observe the injury of lung tissue under microscope.Results There was significant lung injury after blunt chest trauma.The serum concentrations of TNF-α and IL-1β,PMN%and lung wet/dry(W/D)weight were significantly higher in traumatic group(P<0.05,P<0.01).chest trauma,but this protective effect of dexmedetomidine could be blocked by yohimbine,at least in part,via the inhibition of α2-adrenergie receptor.Conclusions Dexmedetomidine has a certain protective effect on acute traumatic acute lung injury in rats.

Objective To evaluate the role of by NO in reduction of myocardial ischemia-reperfusion (IR)injury by ginsenoside Rb1 preconditioning in diabetic rats. Methods Forty healthy adult male SD rats weighing 220-280 g were used in this study. Diabetes mellitus was induced by intraperitoneal streptozotocin 65 mg/kg and confirmed by fasting blood glucose ＞ 16.7 mmol/L. The animals were randomly divided into 4 groups ( n = 10each): sham operation group (group S), group IR, ginsenoside Rb1 group (group R) and L-NAME + ginsenoside Rb1 group (group LR). IR was produced by occlusion of the anterior descending branch of left coronary artery (LAD) for 30 min followed by 120 min reperfusion in group IR, R and LR. In group S, LAD was exposed but not occluded. In group LR, L-NAME 10 mg/kg was injected iv 25 min before ischemia. In group R and LR, ginsenoside Rb1 40 mg/kg was injected iv 10 min before ischemia. In group S and IR, eaqual volume of normal saline was injected instead of ginsenoside Rb1. The blood sample was taken from carotid artery at 120 min of reperfusion for determination of serum activities of creatine kinase (CK) and lactate dehydrogenase (LDH). Then the animals were sacrificed and myocadial tissues were obtained for determination of infarct size, endothelial nitric oxide synthase (eNOS) expression, MDA and NO contents, SOD activity and microscopic examination. Results The serum activities of CK and LDH were significantly increased and the myocardial infarct size was enlarged in group IR, R and LR, and eNOS expression was significantly down-regulated, MDA content was increased, and SOD activity and NO content was significantly decreased in group IR and LR compared with group S ( P ＜ 0.05). The serum activities of CK and LDH, and MDA content were significantly decreased, the myocardial infarct size was reduced, the expression of eNOS was up-regulated and the activity of SOD was increased in group R compared with group IR and LR ( P ＜ 0.05). There was no significant difference in the indices mentioned above between group IR and LR ( P＞ 0.05). Conclusion Ginsenoside Rb1 preconditioning can attenuate myocardial IR injury in diabetic rats via activation of eNOS, increase in NO production, and inhibition of the lipid peroxidation reaction.

Objective: To investigate the effects of low molecular weight heparin(LMWH) on vascular endothelial growth factor(VEGF) expression of early diabetic nephropathy. Methods: Ninety-five male SD rats were randomly divided into three groups: normal control rats, STZ-induced diabetic rats and diabetic rats treated with LMWH. The renal tissues were subjected to immunohistochemical staining after 1,2,4,6,and 8 weeks’ treatment respectively to quantify the VEGF expression. Results: Immunohistochemical staining demonstrated an increasing in VEGF positive cells in diabetic rats. It was found that there were significant differences in VEGF staining intensity between diabetic rats and normal control rats and between LMWH treated rats and untreated diabetic rats after two weeks treatment. Conclusion: The inhibition of VEGF expression may be one of the mechanisms of LMWH’s renal protective effects on early diabetic nephropathy.

OBJECTIVE:To evaluate the pharmacoeconomics of pantoprazole vs. ranitidine in the treatment of gastricesophagitis reflux disease(GERD). METHODS:Retrieved from PubMed,EMBase,The Cochrane Library,CNKI,VIP and Wanfang database, RCTs about pantoprazole vs. ranitidine in the treatment of GERD were selected until Sept. 2014. Two reviewers independently screened literature in accordance with the inclusion and exclusion criteria,and extracted the data of included studies. Stata 12.0 soft-ware was used to estimate therapeutic efficacy index and cost,and cost-effectiveness analysis was performed with the decision tree model. RESULTS:A total of 7 RCTs were included,involving 1 389 patients. Cost-effectiveness analysis showed that for gradeⅠ-Ⅲ(by Savary-Miller standard)GERD,cost-effectiveness ratios of ranitidine were all lower than those of pantoprazole(gradeⅠ:18.86 vs. 57.93;gradeⅡorⅢ:35.58 vs. 146.13);gradeⅠ,Ⅱ,Ⅲincremental cost-effectiveness ratio(ICER)were 335.53,349.85,349.85. Sensitivity analysis supported this conclusion. CONCLUSIONS:Ranitidine is more economic therapy plan for gradeⅠ-Ⅲ GERD, but its ICER fluctuates greatly. Individual therapy plan should be formulated according to disease condition and economic condition.

Objective To analysis the diagnostic values and characteristics of ultrasound and ultrasound guided fine needle aspiration cytology (FNAC) in patients with papillary thyroid carcinoma (PTC) before operation. Methods The data of ultrasound and ultrasound guided FNAC in 129 patients (including 148 PTC nodules) with PTC were collected from January 2014 to February 2017, and the diagnostic reports and feature descriptions of ultrasound and ultrasound guided FNAC were analyzed retrospectively. Results Among the 148 PTC nodules, the ultrasonographic imaging showed that 84.5% (125/148) with low echo-level solid nodules, 61.5% (91/148) with echo heterogenicity, 77.7% (115/148) with a ratio ≥ 1 in longitudinal/breadth, 69.6 % (103/148) with fuzzy boundary, 75.0% (111/148) with microcalcification in nodules, 97.3% (144/148) without or with incomplete aureole, 64.9% (96/148) with rich blood flow and 7.0% (9/129) with enlargement of cervical lymph nodes. The FNAC diagnosis showed that 78.4% (116/148) was diagnosed with suspected papillary carcinoma, 1.4% (2/148) was diagnosed with malignent tumor, 11.5% (17/148) was diagnosed with atypia of undetermined significance (AUS), 1.4% (2/148) was diagnosed with benign lesion, 0.7% (1/148) was diagnosed with follicular neoplasm and 6.7% (10/148) could not be diagnosed. If the suspected papillary carcinoma and malignent tumor were defined as cytodiagnosis, the diagnostic accordance rate with intraoperative pathology was 79.7%. Conclusion The preoperative accuracy rates of ultrasound diagnosis and ultrasound guided FNAC diagnosis for patients with PTC are high, and the characteristics of the both are also typical. The two examinations before operation are helpful for early diagnosis and treatment formulation for patients with PTC.
