Objective To clone and sequence human OPRMI-EXON1, mark it by way of nonisotope-biotin-label, and prepare its probe to study the expression and function of human OPRMI-EXON1. Methods The target gene fragment was amplified by polymerase chain reaction (PCR), and connected to the pGEM-T vector plasmid, then recombined and cloned in competent cell. After that, it was identified by cutting with restriction endonucleases and gene sequence. Finally, we marked it and prepared its probe by nonisotope-biotin-label technique. Results It was demonstrated that the target gene length (2.2kb) amplified by polymerase chain reaction had the same size with the reckoned size in theory and had the same sequence with that of NCBI database. The probe which was used to study the opioid receptor gene was successfully prepared. Conclusion The human OPRMI-EXON1 can be successfully cloned and the probe successfully prepared from the genome, which creates a favorable basis for further research of the morphine-related genes and the expression of their dependence.

Objective To compare the clinical efficacy between laparoscopy and open cholecystectomy for patients of acute calculous cholecystitis. Methods Fifty patients of acute cholecystitis from February 2014 to February 2017 were divided into control group treated with open cholecystectomy and observation group with laparoscopic cholecystectomy;a retrospective analysis was conducted to compare time of resuming peristaltic sound ,postoperative 24h VAS score and hospitalization time. Results There were shorter time of resuming peristaltic sound,higher postoperative 24 h VAS score and shorter hospitalization time in observation group when compared with those in control group (P < 0.05). Conclusions For patients of acute calculous cholecystitis , laparoscopic cholecystectomy,is conducive to shortening patient′s recovery time,alleviating patients′ pain signifi-cantly and decreasing the incidence of complication.

Molecular biology is the fundamental course of life science,and its experimental teaching is difficult to offer due to its long process and need of expensive equipments.Virtual laboratory platform is an important approach for practice teaching in recent years.This article discussed the advantages and requirements,provided the experience of its applying at our university,and suggested that virtual laboratory platform can play a key role in molecular biology experimental teaching.

Objective To investigate the effects of 3％ and 7.5％ hypertonic saline (HS) on hemorrhagic shock patients in Emergency Department.Methods From December 2008 to February 2012,patients older than 15 years with severe trauma and systolic blood pressure (SBP) ≤70 mmHg or 70 to 90 mmHg with heart rate≥ 108 per minute were divided into three groups randomly (random number).Group A:patients treated with 3％ hypertonic saline (HS) 300 mL + lactated Ringer' s solutions (LRS).Group B:patients treated with 7.5％ HS 300 mL + LRS.Group C:patients treated with LRS.The mean arterial pressure (MAP),blood pressure (BP),heart rate (HR) were recorded before infusion and at 10,30,45,60 minutes successively after infusion.Incidence of complications and mortality rates were compared between groups.Results Atotal of 148 patients were enrolled in this study.Compared with LRS grouop,MAP was restored more promptly and maintained persistently in 3％ HS group and 7.5％ HS group,and the total volume of fluid infused was decreased to almost 50％ of LRS in the first 1 hour.No significant differences in MAP levels were observed between group A and B except 30 minutes after infusion.Single bolus of 7.5％ HS infusion resulted in increased of HR to mean 127 beats per minute at 10 minutesafter fluid resuscitation.Higher incidence of arrhythmia and transient hypotension occurred in 7.5％ HS group.There were no statistical differences of changes of electrolytic indices,mortality rates,incidences of ARDS and MODS among three groups.Conclusions Resuscitation with 3％ HS provide similar benefits and lower risk of complications compared with 7.5％ HS and LRS.This study demonstrates the practicability and safety of 3％ HS for fluid resuscitation of patients with hypovolemic shock.

Objective To analyze the anatomic variation of the portal vein based on magnetic resonance angiography using THRIVE sequence in one-stop examination of the liver.Methods Reconstructed three-dimensional images of 648 cases of hepatic portal vein acquired by THRIVE sequence were analyzed.Anatomic variation of the hepatic portal vein was investigated and the diameters of main portal vein (MPV), splenic vein (SV), superior mesenteric vein (SMV) and inferior mesenteric vein (IMV) were measured.Results (1)Four types of different variations of intrahepatic portal vein were observed, with normal type accounting for 79.2% (514/648), type Ⅰ 8.3% (54/648), type Ⅱ 9.0% (58/648) and type Ⅲ 3.4% (22/648), respectively.(2)Four types of different variations of extrahepatic portal vein were also observed, with type Ⅰ accounting for 37.4% (167/447), type Ⅱ 20.4% (91/447), type Ⅲ 36.2% (162/447) and other 6.0% (27/447), respectively.(3)Diameter of MPV, SV, SMV and IMV were (14.03±2.44) mm, (9.51±2.40) mm, (11.14±1.99) mm and (6.01±0.78) mm, respectively.Conclusion It is feasible to analyze anatomic variation in the hepatic portal vein using reconstructed three-dimensional images acquired by THRIVE sequence in one-stop examination of the liver.

It remains a common problem that the evaluation model of course learning for stu-dents is so simple in the higher education of China. Moreover, the teachers are usually used to evalu-ating student's course learning by summative appraisal and ignore process appraisal, so that the stu-dents are usually lack of learning enthusiasm for self study. Besides, the course learning evaluation of students generally lacks the uniform and detail standard in the country. To resolve these problems, a comprehensive evaluation model of course learning based on the principle of talent evaluation has been practiced and improved since 2007 in some basic medical courses at our university. This model is composed of four parts:the evaluation of mastering basic knowledge, the evaluation of the ability to resolve problems through applied knowledge, the evaluation of practical study and the evaluation of learning initiatives. The model has showed in the practice the characteristics of powerful operability, pluralistic evaluating indicators, combining summative appraisal and process one, reflecting objectively the mastering degree of expertise of students and promoting the self-study of students.

Objective To explore the anticancer mechanism of esophageal cancer vaccines and clinical effect.Methods Esophagus cancer cells (Eca109) were cultured and the soluble antigen were extracted from the cells.Esophagus cancer vaccine was constructed with the antigen and superantigen SEC.Lymphocytes were isolated from peripheral blood and then stimulated with the vaccine in vitro.Phenotypes of the cells were checked by FCM and killing activity was tested with cytotoxic assays.One hundred and six early esophageal cancer patients were selected after surgery,who were divided into the observation group of 53 cases with esophageal cancer vaccine therapy and 53 cases in the control group with conventional treatment.Then clinical effect was observated and 3 year follow-up survival rate was observed of the of two groups of patients.Results Proliferation of vaccine stimulated lymphocyte group was the strongest,and high peaked at 72 h (A =0.22),and raise CD8+ T cell populations of CTLs.The killing activity of lymphocyte group stimulated by the vaccine against target cells was significantly higher than that of lymphocyte group ((97.36±2.11) ％) vs.(79.27±5.57) ％,F =38.62,P＜0.01).Three years follow up shows that the survival rates of experiment group were 48.27％ (male) and 45.83％ (female) respectively,and control group were 21.43％ (male) and 24.00％ (female),and the difference was significant (x2 =5.06,6.28,P ＜ 0.05).Conclusion The tumor vaccine constructed with esophagus cancer antigen and superantigen SEC can induce PBMC to activate and proliferate into CD8+ CTL with specific cytotoxicity against the cells which the antigen comes from.The vaccine may raise the survival rate of the patients with Esophagus cancer.
