RESUMO
Objective:To investigate the clinical characteristics of de novo malignancies (DNMs) after liver transplantation (LT) and to study the clinical management strategies.Methods:Adult LT recipients who were regularly followed-up in the Organ Transplantation Center, the Affiliated Hospital of Qingdao University from January 2005 to April 2021 were enrolled in this study. The clinical characteristics of DNMs were retrospectively analyzed. Of 601 LT recipients, there were 105 females and 496 males, aged (51.4±9.6) years old. They were divided into the DNMs group ( n=26) and the non-DNMs group ( n=575) according to whether there were DNMs on followed-up. Clinical data including age, sex, basic diseases before LT and operation time were collected. These patients were follow-up in outpatient clinics. Results:Twenty-six patients were diagnosed to develop DNMs after LT, but there were 28 DNMs (of which 2 patients were diagnosed to have DNMs twice). The incidence of DNMs after LT was 4.3% (26/601), the median time from LT to DNMs was 42 (20, 70) months, and the cumulative incidence rates of DNMs were 0.5%, 2.0%, 6.3%, 21.0% and 34.5% at 1, 3, 5, 10 and 15 years after LT, respectively. Among the 28 DNMs, digestive system tumors were most common, with 17 lesions (60.7%), followed by 3 lesions (11.1%) of lung cancer, 2 lesions (7.4%) of lymphoproliferative diseases, and 1 lesion (3.7%) of cervical cancer, thyroid cancer, soft palate cancer, eyelid cancer, laryngeal cancer, and prostate cancer. The follow-up time of 55.9 (36.6, 102.5) months in the DNMs group after LT was longer than the 33.4 (18.5, 58.9) months in the non-DNMs group ( P<0.001). The 1, 5, and 10 year survival rates of patients with DNMs after LT were 96.3%, 83.5%, and 49.8%, respectively. The 1, 5, and 10 year survival rates of patients with non-DNMs after LT were 94.5%, 77.7%, and 75.4%, respectively. There was no significant difference in the cumulative survival rates between the two groups (log rank=0.402, P=0.526). Conclusion:The incidence of DNMs in LT recipients was 4.3%. The majority of them were digestive system tumors. Early diagnosis and treatment of DNMs significantly improved the prognosis and quality of life of these patients.

RESUMO
Objective To investigate the effect of mosquito control at public environment in residential areas with property management in Wuhan from 2016 to 2018, and to provide background information for making scientific mosquito control strategies in residential areas. Methods The control rate of mosquito route index was taken as the evaluation index. A retrospective analysis of the ocular monitoring results of mosquito breeding sites in the public external environment of property communities in Wuhan from 2016 to 2018 was conducted. Chi-square test was used to compare the route index control rate between different years. Results The residential areas with property management that were effectively incorporated into surveillance were 179 in 2016, 437 in 2017 and 548 in 2018, while the control rate of route index was 51.40%, 59.27% and 41.06%, respectively. The outcome of statistical analysis indicated that the control rate of mosquito route index monitored in 2018 at external environment of residential areas with property management was significantly lower than that in 2017 (χ2=26.342，P<0.001). However, there was no significant difference between the control rate of route index monitored in 2016 and that in later two years. Conclusion Mosquito control effect at public environment on property management areas in Wuhan declined during the consolidation phase of the establishment of national health city. Relevant departments should make effort to explore more reasonable and scientific management strategies and measures for mosquito control to provide more healthy and safe living environment for city residents in Wuhan.

RESUMO
Objective To analyze regularities in selection of analogous points for acupuncture and moxibustion treatment of restless legs syndrome in modern Chinese literature. Three large Chinese databases, China National Knowledge Infrastructure (CNKI), Wan Fang database (Wanfang) and VIP Database (VIP), were searched by computer to retrieve literature on acupuncture and moxibustion treatment of restless legs syndrome. A database of acupuncture and moxibustion prescriptions was set up. The characteristics of and regularities in selection of analogous points for acupuncture and moxibustion treatment of restless legs syndrome were analyzed by use of data mining techniques. Results A total of 107 related articles were included, involving 105 selected acupoints. The main analogous points for modern acupuncture and moxibustion treatment of restless legs syndrome are Zusanli, Sanyinjiao, Chengshan and Yanglingquan. The main meridians that the analogous points belong to are the Bladder Meridian of Foot-Taiyang, the Gallbladder Meridian of Foot-Shaoyang and the Spleen Meridian of Foot-Taiyin. Most of these acupoints are distributed on the lower limb and the lumbodorsal region. The most frequently used specific points that the analogous points belong to are Five Shu points and lower He-Sea point. Association rule analysis shows that the points that are most highly correlated are Yanglingquan and Zusanli. Attention is paid to acupoint selection based on syndrome differentiation and compatible application of local acupoints.Conclusions Selection of analogous points that have the same or similar indications for modern acupuncture and moxibustion treatment of restless legs syndrome makes acupoint combinations produce a synergistic effect and can improve the clinical therapeutic effect.
RESUMO
OBJECTIVE:To establish the method for the determination of plasma concentration of magnesium isoglycyrrhiz-inate in portal vein and peripheral venous blood of patients underwent liver resection,to further validate and evaluate pharmacoki-netic characteristics,rational and safe use of drugs in the clinic. METHODS:31 patients underwent liver resection in our hospital during Oct. 2014-Mar. 2015 were given magnesium isoglycyrrhizinate intravenously at the beginning of surgery. Portal vein and pe-ripheral venous blood of patients were drawn at 1 hour after drug use,and HPLC-UV detection method was used to determine the plasma concentration of drug. RESULTS:The retention time of isoglycyrrhizinate magnesium was 4.5 min,which showed a good peak shape,and was not interfered with the determination by plasma endogenous peak. The plasma concentration ranged from 0.55 to 55.00 mg/L. The minimum quantitative concentration was 0.55 mg/L. The extraction recoveries were 84.7%-87.1%,and method recoveries were 101.2%-105.4%,and RSDs of intra-day and inter-day were less than 6%. Plasma concentration of magnesium iso-glycyrrhizinate in portal vein blood was significantly higher than in peripheral vein blood of patients underwent liver resection (close to 2 times);and plasma concentration was not affected by primary liver diseases and underlying diseases such as cirrhosis. CONCLUSIONS:The method is simple and has high recovery rate of extraction,high accuracy and high sensitivity. It can meet the needs of pharmacokinetic study. After the application of magnesium isoglycyrrhizinate during liver resection,there is higher blood concentration of magnesium isoglycyrrhizinate in portal vein,which is beneficial to protect liver cells and improve liver func-tion. It is suitable during perioperative period of liver.

Objective To investigate the prognostic factors of sorafenib treatment in patients with advanced hepatocellular carcinoma (HCC) underwent surgical therapy or transcatheter arterial chemoembolization (TACE).Methods 62 patients with advanced HCC underwent surgical therapy or TACE were post-treated with sorafenib (400mg,bid).The overall survival (OS) and progress-free survival (PFS) were evaluated by Kaplan-Meier method.Results There were 30 patients in surgical group and 32 patients in TACE group.The median OS in surgical group and TACE group were 12.2 and 5.7 months (P =0.019) and the median PFS were 16.7 and 10.6 months (P =0.033),respectively.The liver cancer volume / liver volume ＞50 ％ and Child-Pugh classification were independent risk factors for PFS in surgical group,the Child-Pugh classification and vascular invasion were independent risk factors for OS in surgical group.Conclusion The patients' PFS and OS in surgical group by oral sorafenib are better than those of patients in TACE group.The effective ways to prolong the PFS include decreasing volume of liver cancer and the better liver function.
RESUMO
@# Objective To explore the optimal experiment conditions of CCK-8 and MTS for cell proliferation assays in human amniotic epithelial cells and to evaluate the cytotoxicity of these reagents. Methods Human amniotic epithelial cells (hAECs) in logarithm growth stages were prepared in different cell concentrations with DMEM/F12 and 10% FBS. The sensitivity and optimal wavelengths was determined based on the optical density (OD) measured at 450 nm and 492 nm. The optimal time was determined under the conditions of the same cell concentration and defined OD values. HAECs were treated with DMSO, CCK-8 and MTS for 1 h, 2 h, 3 h, and 4 h, respectively. 24 h later, cytotoxicity of the CCK-8 and MTS was evaluated by determination of cell proliferation and Trypan Blue staining. Results The optimal detection wavelength was 450 nm for CCK-8, and 492 nm for MTS. The sensitivity of CCK-8 was slightly lower then that of MTS. The optimal time for incubation hAECs with CCK-8 was 4 h within 1~4 h. The inhibitory on cell proliferation and cytotoxicity of CCK-8 were weaker then those of MTS. Conclusion CCK-8 is a convenient reagent with low cytotoxicity for detection of the proliferation of hAECs.
RESUMO
Objective To investigate the prognosis of patients with primary liver cancer in different pathological types after hepatectomy,and to analyze the effects of clinicopathological factors on the survival.Methods The clinical data of 567 patients with primary liver cancer who received hepatectomy at the Affiliated Hospital of Qingdao University from January 1997 to December 2008 were retrospectively analyzed.All patients were divided into hepatocellular carcinoma (HCC) group,cholangiocarcinoma (CC) group and combined hepatocellular carcinoma and cholangiocarcinoma (cHCC-CC) group.The survival and risk factors of the patients were analyzed.All data were analyzed by using the chi-square test,t test,analysis of variance.The survival curve was drawn by the Kaplan-Meier method and the survival of the 3 groups was compared by the Log-rank test.The risk factors were analyzed by the one-way analysis of variance and COX regression model.Results The results of pathological examination confirmed that 92.9％ (527/567) patients were with HCC,4.6％ (26/576) with CC and 2.5％ (14/567)with cHCC-CC.The median cumulative survival time of patients with HCC was 48 months,which was significantly longer than 19 months of patients with CC and 14 months of patients with cHCC-CC (Log-rank value =4.354,8.847,P ＜ 0.05).The median tumor-free survival time of patients with HCC was 26 months,which was significantly longer than 9 months of patients with CC and 9 months of patients with cHCC-CC (Log-rank value =6.479,7.708,P ＜ 0.05).The tumor recurrence rate within 1 year of patients with HCC was 28.8％ (152/527),which was significantly lower than 57.7％ (15/26) of patients with CC or 9/14 of patients with cHCC-CC (F =17.046,P ＜ 0.05).No vascular thrombosis was detected in patients with CC,but the regional lymph node metastasis rate was 19.2％ (5/26),which was significantly higher than 2.8％ (15/527) of patients with HCC (x2 =19.082,P ＜ 0.05).Level of alpha-fetoprotein,TNM staging,tumor diameter,multiple foci,liver capsule invasion,satellite foci and lymph node metastasis were risk factors for the survivals of patients with primary liver cancer after hepateetomy (x2 =8.648,118.786,59.548,7.639,13.200,43.842,15.540,P ＜ 0.05).Vascular tumor thrombosis and Child-Pugh classification were the risk factors for the survivals of patients with HCC or cHCC-CC (x2 =70.446,6.230,P ＜ 0.05).TNM staging,tumor diameter,satellite foci and vascular tumor thrombusis were the independent risk factors for the survivals of patients with primary liver cancer (RR =1.420,1.050,1.513,1.899,P ＜ 0.05) ; TNM staging,tumor diameter and vascular tumor thrombosis were the independent risk factors for the survivals of patients with HCC (RR =1.432,1.888,1.052,P ＜ 0.05).TNM staging and tumor diameter were the independent risk factors for the survivals patients with CC (RR =1.473,1.503,P ＜ 0.05).Conclusion Although CC and cHCC-CC take small proportion in the primary liver cancer,the tumor recurrence rate is higher and the survival rate is lower when compared with patients with HCC.
RESUMO
Objective To study the cause,prevention and treatment of postpancreaticoduodenectomy hemorrhage.Method The clinical data of 422 patients who underwent PD in our hospital between January 2000 and January 2012 were retrospective analyzed.Results The incidence of postoperative hemorrhage was 8.1％ (34/422),and the mortality was 20.6％ (7/34).Early and delayed hemorrhage occurred in 19 and 15 patients,respectively.Intra-abdominal and gastrointestinal hemorrhage occurred in 20 and 14 patients,respectively.For the 19 patients who underwent reoperation,the mortality was 20.6％ (7/34).When compared with the delayed hemorrhage group,the mortality of the early hemorrhage group was significantly lower (P＜0.05).Conclusions Meticulous operation and reliable hemostasis during operation and prevention of pancreatic fistula,biliary fistula and peritoneal fluid collection after operation are the key points in reducing postoperative hemorrhage.A timely and decisive reoperation is important to manage postoperative hemorrhage.
