Objective To observe the efficacy and safety of percutaneous transhepatic cholangial drainage(PTCD)for treating isolated bilioenteric anastomotic stenosis(BAS)after liver transplantation in children.Methods Totally 31 children with BAS after liver transplantation were retrospectively enrolled.PTCD was performed,and the drainage tubes were placed into bilioenteric anastomosis of the second and the third biliary tract for long-term support.Complications after PTCD,success rate of extubation,serum total bilirubin after PTCD and performance of the secondary liver transplantation or not were recorded.Results All 31 cases were successfully treated with PTCD.Delayed recovery after general anesthesia occurred in 1 case after PTCD,which was considered as anesthesia related complication and relieved after symptomatic treatments.No PTCD related complication,such as hemorrhage,infection and biliary fistula occurred.The serum total bilirubin before PTCD was(64.09±24.40)μmol/L,which returned to normal at the first reexamined after treatment with an average of(19.98±3.99)μmol/L.The drainage tubes were successfully extubated in 27 cases,with the success rate of 87.10%(27/31)and the mean drainage time of(7.0±3.7)months.Among the rest 4 cases,further observation was necessary in 2 cases due to intermittent fever,while severe obstruction of bilioenteric anastomosis was found during PTCD,the drainage tube of non-obstruction segment was removed but of obstruction segment was retained in the other 2 cases.No secondary liver transplantation was performed.Conclusion PTCD was effective and safe for treating BAS after liver transplantation in children.

The efficacy of HPV vaccine in preventing cervical cancer has been demonstrated in numerous clinical trials and clinical uses. The follow-up after clinical trials usually last for 5-6 years to evaluate the long-term efficacy, and a series of long-term follow-up studies have been conducted in some regions. The literature retrieval of HPV vaccine long term efficiency research both at home and abroad indicated that the protective efficacy of the vaccine against vaccine-type-related cervical intraepithelial neoplasia grade 2 and above is higher than 90%.

The complement C1q/TNF related protein (CTRP) family is rapidly growing and currently comprises 15 members. Although CTRP proteins share a common structure composed of four distinct domains: a signal peptide at the N terminus, a short variable region, a collagenous domain, and a C-terminal globular domain, which is homologous to adiponectin, each CTRP has a unique tissue expression profile and varied function. In this review we focus on the biochemistry and pleiotropic functions of CTRPs as new molecular mediators regulating cardiovascular metabolic disorders and its related risk factors diseases.

Human epidermal growth factor receptor 2 (HER2) proteins are overexpressed in a high proportion of gastric cancer (GC) cases and affect the maintenance of cancer stem cell (CSC) subpopulations, which are used as targets for the clinical treatment of patients with HER2-positive GC. Despite improvements in survival, numerous HER2-positive patients fail treatment with trastuzumab, highlighting the need for more effective therapies. In this study, we generated a novel type of genetically modified human T cells, expressing a chimeric antigen receptor (CAR), and targeting the GC cell antigen HER2, which harbors the CD137 and CD3ζ moieties. Our findings show that the expanded CAR-T cells, expressing an increased central memory phenotype, were activated by the specific recognition of HER2 antigens in an MHC-independent manner, and effectively killed patient-derived HER2-positive GC cells. In HER2-positive xenograft tumors, CAR-T cells exhibited considerably enhanced tumor inhibition ability, long-term survival, and homing to targets, compared with those of non-transduced T cells. The sphere-forming ability and in vivo tumorigenicity of patient-derived gastric cancer stem-like cells, expressing HER2 and the CD44 protein, were also inhibited. Our results support the future development and clinical application of this adoptive immunotherapy in patients with HER2-positive advanced GC.

Objective To explore the knowledge and training needs of cardiopulmonary resuscitation (CPR) among a health checkup population, and to provide evidence for promoting cardiopulmonary resuscitation knowledge and skills at physical examination centers. Methods Using physical examination numbers, the random number table method was used to randomly select 1 000 people from a health checkup population, information collected including their basic information, cognitive status of cardiopulmonary resuscitation, and attitudes and behaviors toward cardiopulmonary resuscitation. The statistical analysis was performed using χ2test, a one-way ANOVA, and multivariate logistic regression analysis. Results Questionnaires was acquired from 997 consenting adult subjects. From which, 26% had received CPR training, and they demonstrated a low ratio of cognitive knowledge, scoring only 9.94 ± 6.36 (from a possible score of 30). Additionally, 92.1% had a willingness to learn CPR skills, and the CPR performance score was 23.12±3.27 (the highest score was 28). Unmarried people younger than 25 years old, professional and technical personnel, and military men had higher CPR scores than other groups. The CPR learning efficiency of military men, undergraduates, and people younger than 25 years old was higher than other groups. Older people had a lower willingness to learn cardiopulmonary knowledge and the better the feel-good status, the lower the willingness to learn CPR skills, of which OR values were 0.787 and 0.657, respectively (P<0.05). The rate of people learning CPR skills for relatives was higher than for strangers (P<0.05), and 83.8% were willing to receive medical training. Conclusion The health checkup population had a low cognitive level of CPR knowledge, and the willingness to learn CPR was high. To address this, free CPR training should be conducted at medical examination institutions.

Objective: An innovative technique was established to rapidly construct various cell lines that could be induced to express multiple influenza A virus (IAV) proteins. Method: The HA protein genes of multiple IAVs were cloned into the Cumate-induced expression system which was positioned between two PiggyBac transposon sites. These HA plasmids were transfected into the HEK293A cell line with the PiggyBac transposase plasmids. The transfected cells were screened with puromycin, and after that the corresponding virus proteins were induced with Cumate. Results: The results of flow cytometry and Western blotting showed that the virus proteins were expressed in most of the cells in corresponding lines after the induction of Cumate. Conclusion Cell lines which were inducible to express IVA HA protein can be efficiently constructed by using the PiggyBac transposon system.

Objective To study CT-guided localization of additional pulmonary nodules with microcoils prior to video-assisted thoracoscopic surgery (VATS) resection in patients with suspected lung cancer.Methods Eleven patients suspected lung cancer underwent preoperative microcoils localization towards additional small pulmonary nodules.The head of microcoil was pinpointed adjacent to the target nodule while its end tail remained above the visceral pleura.VATS were performed within 24 hours, and comprehensive assessments were conducted according to surgical and pathological outcomes of primary and additional lesions, and suitable surgical processes were followed.Results All 11 localizing pulmonary nodules (4-15 mm in diameter) were successfully removed after VATS, 9 microcoils'' end tails of which were placed above visceral pleural surface.There were no serious complications related with localizing procedure.Other 16 lesions including 11 primary ones were resected.The surgical and pathological outcomes for lung lesions were utterly assessed.Conclusion Microcoil preoperative localization provides helpful orientation for complete resection and assessment of multiple pulmonary lesions in patients with suspected lung cancer.
