Methods In twenty patients with perforating duodenal ulcers, laparoscopic repair of the perforation and laparoscopic freeing of the vagus nerves and highly selective vagotomy(LHSV) were performed, using ultrasonic dissector. Results In all twenty cases the operation was successful. No patient was converted into open HSV. Ulcer symptoms of 15 patients disappeared after operation, and follow up gastroscopy after 6 months showed that the ulcers had healed. The postoperative ulcer symptoms of 5 patients were markedly relieved and were easily controlled by medication. Conclusions The treatment of perforative duodenal ulcer by LHSV has the advantages of minor trauma, rapid postoperative recovery and good results. LHSV is a good procedure for the treatment of perforative duodenal ulcer .

Objective To study the clinical efficacy of acupuncture combined with medication plus joint mobilization in the treatment of lumbar intervertebral disc protrusion accompanied with secondary lumbar spinal stenosis.MethodsTotally 66 cases of lumbar intervertebral disc protrusion accompanied with secondary lumbar spinal stenosis were collected randomly and divided into treatment group (34 cases) and control group (32 cases). The control group was given treatment of simple acupuncture and TCM medication, while the treatment group was given joint mobilization treatment besides acupuncture and TCM medication. Functions of lumbar vertebra were evaluated by ODI scale and the degrees of pain were evaluated by VAS. The clinical efficacy in the two groups was compared. Results ODI in both groups were significantly improved after treatment compared with that before treatment. However, the changing range of the ODI of the treatment group was more significant than that in control group (P<0.01). After treatment, VAS scores were relieved (P<0.05) in both groups, and treatment group was more significant than that in control group (P<0.05). The total clinical efficacy was 97.06% (33/34) in the treatment group, and 84.38% (27/32) in the control group, with statistical significance (P<0.05).Conclusion Acupuncture combined with medication plus joint mobilization in the treatment of lumbar intervertebral disc protrusion accompanied with secondary lumbar spinal stenosis has good efficacy.

AIM: To explore the effect and mechanism of endothelin receptor antagonist on local angiotensin system of hypertrophic myocardial tissue. METHODS: Twenty four rats were randomly divided into 3 groups, control group (CG), hypertrophy group (HG) and endothelin receptor antagonist group (EG). The ratios of left ventricle weight to body weight (LVW/BW) and left ventricle weight to heart weight (LVW/HW) were measured to reflect myocardial hypertrophy. Protein expression of AT1R was detected by immunohistochemistry. The concentration of Ang Ⅱ was determined by ria. Activity of ACE was examined by spectrophotometry. A piece of myocardial tissue was observed in light microscope after HE or VG dyeing. RESULTS:(1) In comparison to CG, LVW/BW, LVW/HW, ACE activity, the concentration of Ang Ⅱ and the expression of AT1R of HG were increased significantly (P

0.05),between the two groups,but in body mass index [(24.451?3.752) vs(22.468?2.434),P=0.030],previous history of pancreatitis(23.8% vs.7.5%,P=0.046) and bloody ascites(95.24% vs.46.24%,P0.05).MODS rate was higher in HL-group(52.4% vs.29%,P=0.04).The two groups had similar operation rates(66.7% vs 80.6%,P=0.178),hospitalization days [(25.476?14.383) vs(22.796?7.191),P=0.216] and mortality rate(28.6% vs.11.8%,P=0.069).Conclusions Hyperlipidemic severe acute pancreatitis has the characters of heavier weight habitus,history of frequent recurrence,high incidence of bloody ascites and prone to develop MOF.

Posterior reversible encephalopathy syndrome is a clinical imaging syndrome associated with multiple pathogenic factors.The main clinical manifestations were headache,seizures,psychotic symptoms,visual disturbance,disturbance of consciousness,etc.The parieto-occipital reversible white matter lesions are the main manifestations of the imaging.If this disease can be diagnosed and treated in time,the clinical symptoms and imaging changes of most patients can be disappeared.If the diagnosis and treatment cannot be obtained in time,it may happen some irreversible damage,serious and even life-threatening,so it is very important to strengthen the understanding,diagnosis and treatment of this disease.At present,the pathogenesis of the disease is still not clear,now reviewed its pathogenesis and imaging manifestation in order to strengthen the clinician's understanding of the disease's pathophysiological mechanism and improve the level of diagnosis.

ObjectiveTo explore the effect of carotid artery sympathetic net exfoliation combined with hyperbaric oxygen therapy on athetosic type cerebral palsy (CP).Methods46 CP children (athetosic type) were divided into the treatment group (n=25) and control group (n=21). All cases of two groups were treated with carotid artery sympathetic net exfoliation as well as children of the treatment group were added with drug and hyperbaric oxygen therapy. Therapeutic effect of two groups was compared.ResultsOne week after operation, the effect rate was 66.67% in control group and 64% in treatment group with no significant difference between two groups. 3 months after operation, the effect rate of the treatment group increased to 96.00%, but that of the control group was not changed, there was a significant difference between two groups (P<0.05).ConclusionCarotid artery sympathetic nerve net exfoliation can improve the symptoms of athetosic type CP children, if combined with hyperbaric oxygen therapy, the curative effect will be further improved.

Objective To study the correlation between the rescue time and the spot survival rate.Method The data of spot-rescued victims in a large public place of Dujiangyan City from 14:35 on May 12,2008 to 11:40 on May 15,2008 were analyzed.The searched-out victims included the spot death and spot survival,and they were statistically analyzed with Chi-Square test and Partitions of X2 method in order to find out correlation between rescue time and survival rate.Results Out of the 366 spot-rescued victims from the ruins,87 ones survived and the spot survival rate was 23.77%.The spot survival rate in the first 24 hours was much higher than that in the second 24 hours(X2=22.62,P＜0.0125)and that in the third 24 hours(X2=37.84,P＜0.0125),and no obvious difference in the spot survival rate between the second and the third 24 hours was found(X2=1.92,P＞0.0125).The first 24 hours was further divided into 3 periods in equal length of time in order to find more subtle differences in early rescue.The spot survival rates in the first and the sccond 8 hours were much higher than that in the third 8 hours(x2=19.33 and 7.11,respectively,P＜0.012 5)while there was no statistical difference in the spot survival rate between the first 8 hours and the second 8 hours(X2=1.75,P＞0.012 5).Conclusions The"golden time"for spot rescuing the victims is the first 24 hours after seismic disaster,the chances to find the survivals is decreasing as the time elapsing.The earlier spot rescue starts in the first golden24 hours,the higher spot survival rate of the seismic victims will be.

A newly developed topological vector of atom Y_C, equilibrium electro-negativity of atom q_e, molecular structural information parameter[N_H~i(i=α, β)] and γ calibration parameter were used to describe the local chemical microenvironment of 63 acyclic alcoholic compounds. Quantitative structural spectrum relationships (QSSR) was systematically made on relationship between ~(13)C NMR chemical shifts of 353 carbon atoms and their molecular structure descriptors. By partial least square regression(PLS), the statistical results indicated that the model correlation coefficient and standard error were 0.9915 and 2.4827, respectively. And the average absolute error was only 2.01×10~(-6) between the calculated and experimental chemical shifts for 353 carbon atoms. To validate the estimation stability for internal samples and the predictive capability for external samples of resulting models, leave-molecule-out(LMO) cross validation(CV) and external validation were performed. Compared with the reported result, not only the number of descriptors employed in this study was much fewer, but also the calculation was much easier.

Objective To investigate the clinical features, operation procedures and clinical outcomes of cervical spondy-lotic myelopathy with different imageological characteristics. Methods Two hundred and twenty one cervical myelopathy with different imageological characteristics patients between November 2011 and October 2013 were involved in this retrospective study. Patients were distributed into three groups, namely mild group (A), moderate group (B) and severe group(C), based on severi-ty of complexity by imageological variables (severity of cervical spine degeneration, the number of spinal cord compression, severi-ty of spinal cord compression and difficulty in operation). Preoperative and postoperative Japanese Orthopaedic Association (JOA) score and mean recovery rate were collected to evaluate the postoperative clinical effects. Demographic data and imageological characteristics were recorded;Univariate analysis or analysis of variance was conducted to analyze the correlation between post-operative JOA recovery rate with gender, age, course of disease, severity of spinal cord compression, the number of segment with spinal cord compression, severity of disc degeneration, MRI T2 increased signal intensity, cervical instability, cervical kyphosis, developmental cervical spinal stenosis and ossification of posterior longitudinal ligament. Results There was no significant differ-ence in gender between three groups. There was significant difference in age, preoperative JOA score and improvement rate be-tween group A and group B (C). All patients received decompression and reconstruction by anterior or posterior approach. The ra-tio of anterior approach in group A, B and C was 91.1%(72/79), 79.8%(71/89), 35.8%(18/53). The last follow-up JOA recovery rate of group A, B and C was 75.4%±6.4%、67.7%±8.7%、62.8%±10.4%. The last follow-up JOA recovery rate was correlated with duration of disease, the number of spinal cord compression and severity of spinal cord compression. Age, duration of course, preop-erative JOA score, degree of cord compression, the number of segment with cord compression, degree of disc degeneration, MRI T 2 increased signal intensity, cervical instability, cervical kyphosis, developmental cervical spinal stenosis and OPLL. Conclusion Patients suffering from cervical myelopathy with different imageological have good prognosis by appropriate operation procedure.
