ABSTRACT

Cancer-associated fibroblasts (CAFs) are one of the most important cellular components of the tumor microenvironment in pancreatic ductal adenocarcinoma. CAFs acquire an activated phenotype via various cytokines, promote tumor proliferation and growth, accelerate invasion and metastasis, induce angiogenesis, and enhance chemical drug resistance. Therefore, studies on the interaction between CAFs and pancreatic ductal adenocarcinoma cells are expected to improve the diagnostic and therapeutic value of patients with pancreatic ductal adenocarcinoma from the perspective of tumor microenvironment.

ABSTRACT

Objective To investigate the clinical features and treatment of residual gallbladder lesions after cholecystectomy.Methods The retrospective cross-sectional study was conducted.The clinicopathological data of 83 patients with residual gallbladder lesions after cholecystectomy who were admitted to the Affiliated Hospital of Inner Mongolia Medical University between January 2009 and April 2016 were collected.Among the 83 patients,74 had residual gallbladder (41 combined with bile duct stones and 33 with simple residual gallbladder)and 9 had simple residual bile duct stones.Patients received laboratory and imaging examinations,and then selected suitable surgery according to residual lesions.Observation indicators included:(1) clinical features:medical history,clinical manifestation,features of laboratory and imaging examinations;(2) surgical and postoperative situations:surgical procedure,operation time,volume of intraoperative blood loss,time of drainagetube removal,postoperative complications and duration of postoperative hospital stay;(3) postoperative pathological examination;(4) follow-up situation.Follow-up using outpatient examination and telephone interview was performed to detect survival of patients and recurrence of lesions using abdomen color Doppler ultrasound up to October 2016.Measurement data with normal distribution were represented as ~ ±s.Results (1) Clinical features:① medical history:all the 83 patients had histories of cholecystectomy,including 57 with emergency operation and 26 with selective operation.② Clinical manifestation:initial clinical manifestation occurred at 1-324 months postoperatively,with an average time of 96 months.Of 83 patients,49 had right upper abdominal colic associated with right shoulder or back rediating pain,fever,nausea and vomiting,24 had jaundice as the main symptoms,8 had gradually worse conditions,with right upper quadrant abdominal pain,chills and fever associated with jaundice in the advanced stage and 2 had abdominal discomfort associated with incomplete intestinal obstruction.③ Laboratory examination:elevated alanine transaminase (ALT) and aspartate transaminase (AST) levels were detected in 48 patients,elevated total bilirubin (TBil) level in 28 patients and elevated serum and urinary amylase level in 4 patients,respectively.④ Imaging examination:of 83 patients,77 had positive results of magnetic resonanced eholangio-pancreatography (MRCP),43 had positive results of abdominal color Doppler ultrasound and 39 (4 combined with pancreatitis) had positive results of abdominal computed tomography (CT).(2) Surgical and postoperative situations:all the 83 patients underwent surgery.Of 74 patients with residual gallbladder,72 underwent residual gallbladder resection (of 41 combined with bile duct stones,35 undergoing residual gallbladder resection + bill duct exploration and removing the stone + T-tube drainage,6 initially undergoing endoscopic sphincterotomy for removing bile duct stones and then residual gallbladder resection and 31 undergoing simple residual gallbladder resection),1 combined with residual gallbladder cancer underwent residual gallbladder resection + common bile duct resection + hepatic duct-jejunum internal drainage and 1 combined with residual gallbladder cancer and common bile duct space-occupying lesion underwent palliative biliary-enterostomy.Nine patients with simple residual bile duct stones underwent endoscopic sphincterotomy for removing bile duct stones.Operation time,volume of intraoperative blood loss,time of drainage-tube removal and duration of postoperative hospital stay were (92±39)minutes,(63±12)mL,(5±4)days and (9±5)days in 74 patients with residual gallbladder,respectively.There was no severe postoperative complication.Operation time,volume of intraoperative blood loss and duration of postoperative hospital stay were (57±33)minutes,(25±9)mL and (5 ± 3) days in 9 patients with simple residual bile duct stones,respectively.No severe complication was occurred in 9 patients.(3) Postoperative pathological examination:the length of residual cystic duct in 74 patients with residual gallbladder was (2.8 ± 1.0) cm,combining with stones.Of 74 patients,simple hyperplasia of residual gallbladder were detected in 54 patients,dysplasia in 14 patients,tumor-like hyperplasia and benign tumor in 4 patients and adenocarcinoma in 2 patients.(4) Follow-up situation:all the 83 patients were followed up for 6-71 months,with a median time of 33 months.Eighty-one patients were healthy survival,without recurrence of lesions.One patient had recurrence of bile duct stones at 34 months postoperatively,and then was cured by choledochojejunostomy,without recurrence up to the end of follow-up.One patient with residual gallbladder cancer complicated with common bile duct space-occupying lesion died at 9 months postoperatively.Conclusions Patients have recurrent right upper abdominal colic associated with right shoulder or back rediating pain,fever and jaundice after cholecystectomy,and lesions of residual gallbladder or bile duct stones should be considered.Reoperation is safe and feasible for patients,with a good clinical outcome.

ABSTRACT

Objective To better understand the knowledge, attitudes, practice (KAP) status and relative demand to post abortion family planning service (PAFPS) in medical staffs of obstetrics and gynecology department in Tianjin. Meth?ods By using random, stratified and clustered sampling approach, 290 obstetrics and gynecology personnels in Tianjin were selected. A Self-Administered Questionnaire on PAFPS KAP was employed to survey the general characteristics, aware?ness of PAFPS knowledge, attitudes to PAFPS and the occurrence of unintended pregnancy themselves, and service capabili?ties of PAFPS and request of continuing education. Results The respondents showed defects in PAFPS forms, follow-up ar?rangements and contraceptive method after abortion. The average knowledge score was higher in tertiary medical institution than that of secondary medical institutions. The score was higher in clinical doctors than that of nurses, and the higher the ti?tle, the higher the score. The 95.34%of respondents believed that it was necessary to develop PAFPS widely. But 93.55%of respondents thought that it can be difficult to carry out PAFPS as being required because of unclear service process, shortage of funds, human resource constraints, inadequate facilities and weak sense of services. The 53.36%of respondents, who had sexual life history, occurred unintended pregnancy themselves. The current defects of PAFPS were no standardized service processes, missing of medium-term and long-term follow-up, missing of collective consulting, providing contraceptives not timely and hadn′t pay attention to contraceptive advice. There were 90.68%medical personnels showed demand on relative training. Conclusion It′s necessary to perform continuing education about PAFPS to obstetrics and gynecology personnels via different intervention. At the same time, we should increase investment and make the service processes perfectly, so as to improve the level of PAFPS in obstetrics and gynecology medical staffs.

ABSTRACT

Objective: In order to observe the kinds and intensity of the working noise of Yansan Petrochemical Co. and the effects caused by the working noise on the workers' vestibular and auditory function. Method :The intensity and frequency of the working noise were recorded by exactolnoisemeter in the workshop. One hundred and seventeen workers were tested in routine pure-tone tested method. The SPVN and ABR were tested within fifty-one workers of all. Result:The working noise of Yansan Petrochemical Co. belongs to the broad band and steady noise. The intensity of the working noise were during 85.7~104.0 dB (A) and the main frequency were during 1~8 kHz. About 59 percent workers who exposed to the working noise had hearing loss. The most hearing-loss were in the high frequency. The hearing-loss of speech frequency were slight. Workers who have more six years standing have obviously increased hearing-loss than the workers who have less five years standing. There were significant differences the ABR thresholds and wave-interval between the tested and controlled groups. The SPVN and CP were abnormal in more than 17.4 percent workers with hearing loss. Conclusion: The working noise of Yansan Petrochemical Co. belongs to the broad band and steady noise. Working noise can lead to workers' hearing loss of certain degrees who exposed in the noise for a long time. Obvious correlation was not defined between the hearing-loss and the abnormal vestibular response group.
