Surgical resection remains the only curative option of treatment for hepatocellular carcinoma,but centrally located tumors remain problematic.Extended right or left hepatectomy removes 60% to 85% of the hepatic parenchyma and is associated with more hepatic failure.Mesohepatectomy,resection of central hepatic segments (Couinaud's segments Ⅳ,Ⅴ,Ⅷ) and leaving the right and left segments in situ,preserves more functional hepatic tissues than extended hepatectomy.Despite its technical demands,mesohepatectomy should be considered as an alternative treatment for central huge hepatic tumors.

Objective:To investigate the impact of self-concealment,self-disclosure,coping style and per- ceived social support on university students'loneliness.Methods:Loneliness and related factors were assessed among 482 university students using scales including UCLA Loneliness Scale,Self-concealment Scale(SCS),Self-disclosure Index(SDI),Simplified Coping Style Questionnaire(SCSQ)and Perceived Social Support Scale(PSSS).Results: The level of university students'loneliness was not high(36.5?7.4);males experienced more loneliness than fe- males(37.4?7.5/35.4?7.3,F=8.25,P0.05). Regression analysis showed that SCS,SCSQ and PSSS predicted UCLA effectively(?=0.207,-0.218,0.157, -0.380).The testing of mediating effect indicated that SCS had direct and indirect impact on UCLA through nega- tive coping style and PSSS;SDI had only indirect impact on UCLA through positive coping style and PSSS.Conclusion:SCS,SDI,SCSQ and PSSS are important factors influencing UCLA,and the intervention of univer- sity students'loneliness should focus on these variables.

Objective:To investigate the clinical efficacy of pancreaticodudenectomy (PD) using anterior approach in situ technique for pancreatic head cancer.Methods:The retrospective cohort study was conducted. The clinicopathological data of 285 patients with pancreatic head cancer who were admitted to the First Affiliated Hospital of Kunming Medical University from January 2012 to June 2018 were collected. There were 164 males and 121 females, aged from 40 to 76 years, with an average age of 57 years. Of the 285 patients, 196 patients who underwent PD using anterior approach in situ technique were set as anterior approach group, 89 patients who underwent PD using traditional approach were set as traditional approach group. Observation indicators: (1) surgical situations; (2) postoperative situations; (3) follow-up. Follow-up was performed by outpatient examination, telephone or network interview once every 2 to 3 months to detect tumor recurrence, metastasis and survival of patients up to December 2018. The endpoint of follow-up was death of patients, and the secondary endpoint of follow-up was tumor recurrence or metastasis. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was analyzed by the t test. Measurement data with skewed distribution were represented as M (range), and comparison between groups was analyzed by the Mann-Whitney U test. Count data were represented as absolute numbers or percentages, and comparison between groups was analyzed by the chi-square test. Kaplan-Meier method was used to draw the survial curve and calculate the survival rates. Survival analysis was done by the Log-rank test. Results:(1) Surgical situations: 285 patients underwent surgery successfully. Cases with pylorus-preservaction, cases with superior mesenteric vein/ portal vein (SMV/PV) resection and reconstruction (end to end anastomosis, artificial vascular replacement, lateral wall resection and anastomosis), operation time, volume of intraoperative blood loss were 118, 37 (17, 11, 9), (303±107)minutes, 350 mL(range, 100-750 mL) in the anterior approach group, and 48, 9 (7, 1, 1), (335±103)minutes, 400 mL(range, 100-900 mL) in the traditional approach group, respectively, showing no significant difference between the two groups ( χ2=0.990, 3.474, t=0.722, Z=1.729, P>0.05). (2) Postoperative situations: the rate of R 0 resection, the number of lymph node dissected, the number of positive lymph node dissected, rate of nerve invasion, rate of vascular invasion, cases with postoperative severe complica-tions, the number of perioperative death, cases with postoperative chemotherapy were 93.88%(184/196), 12(range, 5-19), 4(range, 0-15), 45.41%(89/196), 31.12%(61/196), 28, 3, 69 in the anterior approach group, and 85.39%(76/89), 7(range, 4-17), 5(range, 0-13), 32.58%(29/89), 23.60%(21/89), 11, 2, 41 in the traditional approach group, respectively. There were significant differences in the rate of R 0 resection, the number of lymph node dissected, rate of nerve invasion between the two groups ( χ2=5.506, Z=4.637, χ2=4.149, P<0.05), while there was no significant difference in the number of positive lymph node dissected, rate of vascular invasion, cases with postoperative severe complications, the number of perioperative death, cases with postoperative chemotherapy between the two groups ( Z=0.052, χ2=1.962, 0.192, 0.001, 3.048, P>0.05). (3) Follow-up: of the 285 patients, 252 and 228 achieved the secondary endpoint and the endpoint of follow-up respectively with the follow-up time of 35 months (range, 6-58 months). There were 181 and 176 of 196 patients in the anterior approach group achieving the secondary endpoint and the endpoint of follow-up respectively with the follow-up time of 38 months (range, 6-58 months). There were 71 and 52 of 89 patients in the traditional approach group achieving the second endpoint and the endpoint of follow-up respectively with the follow-up time of 33 months (range, 7-53 months). The median tumor free survival time and median overall survival time were 31 months and 37 months in the anterior approach group, respectively, versus 24 months and 31 months in the traditional approach group. There was a significant difference in the tumor free survival between the two groups ( χ2=7.646, P<0.05), while no significant difference in the overall survival between the two groups ( χ2=3.265, P>0.05). Conclusion:PD using anterior approach in situ technique is safe and feasible for pancreatic head cancer, which can improve the rate of R 0 resection and prolong the tumor free survival time of patients.

Primary intrahepatic stones (PIS) is a refractory disease with a high incidence rate in southwest China, and some patients still require surgery again or even more times after initial treatment. Many studies in recent years have shown that some specific flora can colonize in the intrahepatic bile duct, leading to chronic infection and inflammation of the biliary system, and these specific types of flora, called "stone-causing flora", can produce metabolites such as β-glucuronidase and play an important role in the formation of pigmented stones. This article analyzes the role of stone-causing flora in the pathogenesis of PIS, so as to provide more treatment options for PIS patients.

Background: Cardiopulmonary resuscitation (CPR) strategies in COVID-19 patients differ from those in patients suffering from cardiogenic cardiac arrest. During CPR, both healthcare and non-healthcare workers who provide resuscitation are at risk of infection. The Working Group for Expert Consensus on Prevention and Cardiopulmonary Resuscitation for Cardiac Arrest in COVID-19 has developed this Chinese Expert Consensus to guide clinical practice of CPR in COVID-19 patients. Main recommendations: 1) A medical team should be assigned to evaluate severe and critical COVID-19 for early monitoring of cardiac-arrest warning signs. 2) Psychological counseling and treatment are highly recommended, since sympathetic and vagal abnormalities induced by psychological stress from the COVID-19 pandemic can induce cardiac arrest. 3) Healthcare workers should wear personal protective equipment (PPE). 4) Mouth-to-mouth ventilation should be avoided on patients suspected of having or diagnosed with COVID-19. 5) Hands-only chest compression and mechanical chest compression are recommended. 6) Tracheal-intubation procedures should be optimized and tracheal-intubation strategies should be implemented early. 7) CPR should be provided for 20-30 min. 8) Various factors should be taken into consideration such as the interests of patients and family members, ethics, transmission risks, and laws and regulations governing infectious disease control. Changes in management: The following changes or modifications to CPR strategy in COVID-19 patients are proposed: 1) Healthcare workers should wear PPE. 2) Hands-only chest compression and mechanical chest compression can be implemented to reduce or avoid the spread of viruses by aerosols. 3) Both the benefits to patients and the risk of infection should be considered. 4) Hhealthcare workers should be fully aware of and trained in CPR strategies and procedures specifically for patients with COVID-19.
