Objective To discuss application value of intestinal electromyography in patients with hepatic cirrhosis and to observe intestinal myoeletric activity.Methods There were 65 cases of hepatic cirrhosis in expermental group and 30 cases in control group. All the cases were recorded body surface intestinal electromyography using gastrointestinal myoelectric analyzer(WCDF-4B, Hefei , P.R.China). The parameters included average peak range-Ap, main frequency-Fp, average over zero frequency-Fz and special wave form were surveyed.Results Sharp higher Fz abnormal rate and emergence rate of special wave form in hepatic cirrhosis group were higher than in control group,P0 05.Conclusions In hepatic cirrhosis group,Fz was much higher than that in control group. And the intestinal myoelectric activity increased in the patients with hepatic cirrhosis,which represented by appearance of characteristic wave form that was frequent micromigration wave as well as load wave. Those changes accounted for heighten and irregularity of excitability intestinal myoelectric activity. Moreover, it will increase for the incidence of abnormality of intestinal myoelectric activity along with damage degree of hepatic function. Intestinal electromyography is a reliable method to judge intestinal myoelectric activity, the method has characteristics of harmless,free pain, convenient, safty and steady.

During the teaching activities, to stimulate students' subject awareness and encour-age them to play the main role in class activities are inevitable trends in the reform of college educa-tion. Students’ subjective activity is a key to the teaching effect of regional anatomy, a course mainly based on experimental program. Department of Human Anatomy in Chongqing Medical University lay-outs regional anatomy teaching program to develop the students' subjective activities in learning from the course specialty: in preview and review, to train students' image-thinking by drawing; in anatomi-cal operation link, to cultivate students' interest in learning and innovation by discussing the relation-ship of anatomical structure and clinical disease and identifying the variation of structure; in the eval-uation process, taking the formative evaluation system to promote the students' initiatives and ensure the objectiveness and fairness. The implementation of these measures promotes the regional anatomy teaching quality.

Objective To investigate the levels of IL-6 in serum and gastric mucosa of servicemen before and after mili-tary maneuver and their significance .Methods The level of serum IL-6 in 60 servicemen was studied by enzyme-linked immunosorbent assay .The expression of IL-6 in gastric mucosa from the 60 servicemen was detected by immunochemical staining.Results The level of IL-6 in serum of servicemen after military maneuver was significantly higher than that before military maneuver (P<0.01).IL-6 was found to be expressed in the cytoplasm of epithelioglandular cells and also in the cytoplasm of mesenchymal cells .The expression of IL-6 in gastirc mucosa was significantly stronger after military maneuver than before military maneuver (P<0.01).Conclusion IL-6 might be involved in the development of pathological changes in gastric mucosa caused by military stress in troops .Examination of the level of IL-6 in the early stage of military stress might help assess the chance of gastric mucosa lesion and its severity .

Objective:To study the safety and efficacy on timing of associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) stageⅡbased on increase in remnant liver volume.Methods:19 patients (male: female 13: 6; average age 53 years) with liver tumors treated by ALPPS from April 2014 to December 2020 were retrospectively studied. Patients with FLV/ESLV (future liver volume/ estimated standard liver volume) increase of more than 50% within 1 week followed by stageⅡALPPS were included into the rapid group ( n=8). Those who failed to have 50% increase in FLV/ESLV within 1 week were included into the control group ( n=11). The two groups were compared in the ALPPS stage II in operating time, blood loss, postoperative complications, mortality rate and hospital stay. Results:All 19 patients underwent ALPPS stage II uneventfully. One patient in the control group died from liver failure within 30 days of operation. The operation time (3.2±1.8)h, blood loss (554±227) ml and postoperative hospital stay (12.6±2.4) d in the rapid group were significantly better than those in the control group (4.7±2.2) h, [(760±314) ml, (18.2±6.4) d (all P<0.05)]. The two groups had similar complication rates in both post stageⅠ[37.5%(3/8) vs. 45.4%(5/11)] , or stageⅡ [37.5%(3/8) vs. 36.4%(4/11)] (both P>0.05). Conclusion:Rapid increase in FLR volume of more than 50% within a week was safe and feasible to proceed to ALPPS stage II. This conclusion needs to be confirmed by further studies using large sample sizes.

It is an important way to improve the teaching quality by carrying out innovative experiments among medical students. In the process of experimental teaching, anatomy teachers expand the anatomy knowledge to basic scientific research techniques, so as to enhance students' confidence in participating in innovative experimental projects. Meanwhile, the teachers combine introduction of the anatomical structures with hot medical research issues, in order to help students to select appropriate innovative experimental topics. What's more, the new media teaching is integrated into the teaching of anatomy, enlightening students to perfect the experimental designs. Finally, in the teaching practice of regional anatomy, students are guided to carry out innovative experiments and write research papers. Abovementioned measures not only improve the teaching quality of anatomy, but also improve the students' scientific research ability, laying a foundation for them to participate in innovative experimental projects.

Objective To investigate the correlation between atherogenic index of plasma (AIP) and the severity of hypertriglyceridemic acute pancreatitis (HTG-AP) and the value of AIP combined with Bedside Index for Severity in Acute Pancreatitis (BISAP) score in the early prediction of severe HTG-AP (sHTG-AP). Methods A retrospective analysis was performed for the clinical data of 170 patients with HTG-AP who were hospitalized in The General Hospital of Central Theater Command from January 2017 to December 2021, and according to related guidelines, they were divided into the sHTG-AP group with 28 patients and non-sHTG-AP group with 142 patients. Peripheral blood samples were collected from all patients within 24 hours after admission, and the two groups were compared in terms of sex, age, laboratory test results, AIP, BISAP score, and modified CT severity index (MCTSI) score. The chi-square test or the Fisher's exact test was used for comparison of categorical data between groups; the Mann-Whitney U test was used for comparison of continuous data between groups. The Spearman rank correlation test was used to investigate the correlation between each factor and the severity of HTG-AP, and the binary logistic regression analysis were used to investigate the independent risk factors for sHTG-AP. The receiver operating characteristic (ROC) curve was plotted to assess the predictive efficacy of each indicator. Results There were significant differences between the two groups in the medical history of diabetes, lymphocyte count, albumin, Ca 2+ , triglyceride, high-density lipoprotein cholesterol, AIP, BISAP score, MCTSI score, length of hospital stay, and hospital costs (all P < 0.05). The sHTG-AP group had a longer length of hospital stay, higher hospital costs, and a higher AIP value. AIP (odds ratio [ OR ]=1.244, 95% confidence interval [ CI ]: 1.062-1.458, P =0.007), BISAP score ( OR =5.525, 95% CI : 1.646-18.543, P =0.006), and MCTSI score ( OR =2.029, 95% CI : 1.245-3.305, P =0.004) were risk factors for sHTG-AP. AIP, BISAP score, and MCTSI score were positively correlated with the severity of HTG-AP ( r =0.291, 0.631, and 0.649, all P < 0.001), and AIP was positively correlated with BISAP score and MCTSI score ( r =0.190 and 0.215, both P < 0.05). AIP had an optimal cut-off value of 1.095 in predicting sHTG-AP, and AIP, BISAP score, and AIP combined with BISAP score had an area under the ROC curve of 0.759, 0.887, 0.925, respectively, a sensitivity of 0.821, 0.857, and 0.786, respectively, and a specificity of 0.627, 0.817, and 0.937, respectively (all P < 0.001). Conclusion AIP is a risk factor for sHTG-AP and is correlated with disease severity, and AIP combined with BISAP score has a relatively high value in the early prediction of sHTG-AP.
