The incidence of cervical cancer is the first place in gynecological malignant tumors in China. About 500,000 new cases accounts for 5% of all new cancer patients appeared per year all over the world.How to prolong the progression free survival and overall survival of patients with cervical carcinoma is a very important issue in the field of gynecology.So it is very important to take effective treatment.This paper reviewed the research progress of cervical carcinoma treatment in recent years,including surgical treatment,chemotherapy drugs thera?py,angiogenesis inhibitors targeted therapy,immunization therapy.

Objectives: To assess the feasibility and stability of right ventricular outflow tract (ROVT) pacing under current technology by comparing the results of ROVT pacing with the traditional right ventricular apex (RVA) pacing. Methods: A total of 42 patients (at mean age of 63.5±10.4 years) without structural heart disease were randomly divided into two groups. RVA pacing group (n=14),and RVOT pacing group(n=28). An active fixation lead was implanted in all patients whose pacemaker could automatically measure the pacing threshold every day. The operation time,X-ray exposure time and lead parameters detected during the operation were collected to evaluate the feasibility of RVOT pacing. The complications related to lead and implantation procedure and the trend of threshold change during the follow-up time were used to assess the stability of RVOT pacing.Results: There were no statistic differences between RVA pacing group and RVOT pacing group in terms of operation time,X-ray exposure time and lead parameters. In RVOT group,the change of threshold during acute period was similar to those in RVA group (P=0.23). Chronic pacing threshold was also comparable between two groups,mean threshold at 6 months follow-up time was 0.55±0.11V and 0.54±0.09V at 0.4 pulse width in RVA group and RVOT group respectively (P=0.787).Conclusion: RVOT pacing was feasible and stable in operation time and lead characteristics compared with the conventional RVA pacing under current pacing technology.

The neurofilament proteins (NFPs) from different neuronal tissues including Alzheimer and Huntington disease gray matter, rat brain gray, white matter and spinal cord were separated biochemically into two major fractions. A systematic investigation on the distribution, expression and phosphorylation of NFPs in those fractions was undertaken in the present study. It was found that only non-phosphorylated NF-H and NF-M, but not NF-L subunit were detected in Alzheimer brain gray matter high speed supernatant, whereas all neurofilament subunits including non-phosphorylated and phosphorylated were measured in high speed pellet fraction of the same tissue. The hyperphosphorylation of NF-H and NF-M in Alzheimer brain was shown by phosphorylation dependent monoclonal antibodies SMI31 and SMI34. This hyperphosphorylation was confirmed by non-phosphorylation dependent antibody SMI32 with dephosphosphorylation of the samples. Furthermore, an increased amount of NF-H, NH-M and NF-L, detected by SMI33 and NR4 respectively, was also observed in Alzheimer samples, in which the elevation in NF-L was significant. A significantly different immunoblot patterns in distribution, expression and phosphorylation were determined in various position of the neural system and alternative fractions. To our best knowledge, this is the first data shown definite abnormality of NFPs in Alzheimer disease. The information obtained in the present study will be extremely valuable in further study of the proteins both in physiological and pathological conditions.

Objective:To identify the risk factors for postoperative nausea and vomiting (PONV) in the patients undergoing thoracic surgery.Methods:The medical records of patients of either sex, aged 18-80 yr, of American Society of Anesthesiologists physical status Ⅰ-Ⅲ, underwent elective thoracic surgery from January 2018 to January 2020, were collected retrospectively.The age, gender, educational background, American Society of Anesthesiologists physical status, motion sickness, history of smoking, history of drinking, history of heart disease, history of hypertension, history of diabetes, preoperative blood routine, liver function, parameters of electrolytes; operation method, type of operation, operation time, intraoperative nerve block, consumption of dexamethasone before anesthesia induction and intraoperative sufentanil and dexmedetomidine, use of postoperative patient-controlled intravenous analgesia (PCIA), and postoperative rescue opioid analgesics and antiemetics were recorded.The patients were divided into PONV group and non-PONV group depending on the occurrence of nausea and vomiting within 24 h after operation.PONV group was further divided into nausea group (PON group) and vomiting group (POV group) according to whether vomiting occurred.Logistic regression analysis was used to identify the risk factors for PONV.Results:A total of 3 791 patients were enrolled in this study, with 144 cases in PONV group and 3 647 cases in non-PONV group.The incidence of PONV was 3.80%.There were 38 patients in POV group, and the incidence was 26.4%.The results of logistic regression analysis showed that motion sickness, female, pulmonary wedge resection, postoperative PCIA and increased use of postoperative rescue opioid analgesics were risk factors for PONV in the patients undergoing thoracic surgery, intraoperative use of dexmedetomidine was a protective factor for PONV; motion sickness, female and history of hypertension were risk factors for postoperative vomiting in the patients at risk for PONV ( P<0.05). Conclusions:Motion sickness, female, pulmonary wedge resection, postoperative PCIA, and increased use of postoperative rescue opioid analgesics are risk factors and intraoperative use of dexmedetomidine is a protective factor for PONV in the patients undergoing thoracic surgery; motion sickness, female and history of hypertension are risk factors for postoperative vomiting in the patients at risk for PONV.

Non-alcoholic fatty liver disease (NAFLD) is characterized by increased fat depositions in the liver while the patients do not have drinking history.NAFLD has a prevalence of 10％ ～40％ in global,25％ ～26％ in Western populations.From 2004 to 2013,the numbers of new patients on the waitlist who had NASH increased by 170％ in America.The prevalence of NAFLD in China is 20％.With the decrease of HBV and HCV and the increase of diabetes mellitus type 2 and obesity,NAFLD will become the most common chronic liver disease in China over the next 20 years.NAFLD related end-stage liver disease will become the most common indication of liver transplantation.In this paper,the epidemiological features,pathogenesis,indication and prognosis of liver transplantation are reviewed.

Objective:To identify the risk factors for postoperative sleep disturbances in elderly patients undergoing thoracic surgery.Methods:A total of 200 elderly patients of both sexes, aged>65 yr, of American Society of Anesthesiology physical status Ⅱ or Ⅲ, scheduled for elective thoracic surgery, were enrolled in the study.Data regarding patient age, gender, body mass index (BMI), American Society of Anesthesiologists physical status, history of hypertension, history of diabetes mellitus, operation method, type of operation, operation time, intraoperative blood loss, use of intraoperative nerve block and use of dexmedetomidine in patient-controlled intravenous analgesia (PCIA) were collected.The patients were followed up after operation, the occurrence of postoperative pain at 48 h after operation was recorded, and patients′ subjective sleep quality at 48 h after operation was assessed using the Pittsburgh Sleep Quality Index Questionnaire (PSQI). Patients were divided into 2 groups according to PSQI score: non-postoperative sleep disturbances group (PSQI score<5) and postoperative sleep disturbances group (PSQI score≥5). A multivariate logistic regression was used to identify the risk factors for postoperative sleep disturbances in elderly patients undergoing thoracic surgery.Results:A total of 169 patients were included in this study, and the incidence of postoperative sleep disturbances was 45%.The results of logistic regression analysis showed that history of preoperative insomnia, BMI≥24 kg/m 2, diabetes mellitus, thoracic surgery, radical resection of lung cancer, radical resection of esophageal cancer, operation time≥120 min and moderate and severe postoperative pain were risk factors for postoperative sleep disturbances in elderly patients undergoing thoracic surgery, and use of intraoperative nerve block and use of dexmedetomidine during PCIA were protective factors for postoperative sleep disturbances in elderly patients ( P<0.05). Conclusion:History of preoperative insomnia, BMI≥24 kg/m 2, diabetes mellitus, thoracic surgery, radical resection of lung cancer, radical resection of esophageal cancer, operation time≥120 min, moderate and severe postoperative pain are risk factors and use of intraoperative nerve block and use of dexmedetomidine during PCIA are protective factors for postoperative sleep disturbances in elderly patients undergoing thoracic surgery.

Primary liver cancer has the features of high malignancy, rapid progression, frequent recurrence/metastasis, and high mortality, and therefore, most patients have developed intrahepatic or extrahepatic metastasis when attending the hospital and thus lost the opportunity for surgical treatment. Chimeric antigen receptor T-cell (CAR-T) immunotherapy has achieved good efficacy in the treatment of B-cell acute lymphoblastic leukemia, and clinical trials have been initiated to explore its applications in solid tumors such as primary liver cancer, pancreatic cancer, gastric cancer, and prostate cancer. This article reviews the efficacy of CAR-T immunotherapy in the clinical trials for primary liver cancer and discusses the difficult issues that need to be solved in clinical practice, such as the lack of suitable tumor targets, the inhibitory effect of tumor microenvironment on CAR-T cells, and the poor infiltration of CAR-T cells in tumor tissue, so as to provide a reference for related clinical studies.
