Objective To investigate the clinical safety of preoperative lymphatic chemotherapy in the treatment of reetal cancer.Methods The regional and systemic symptoms,postoperatwe stoma healing,haematogenesis.functions of hean,liver and kidney after lymphatic chemotherapy,and the level of CD3+,CD4+,CD8+,CD4+/CD8+,CD(16+56)+in blood 30 minutes before and 48 hours after lymphatic chemotherapv were detected.Results There were no significant effects of lymphatic chemotherapy on the regional and systemic symptoms,postoperative stoma healing,haematogenesis and the functions of heart,liver and kidney.The level of CD4+/CD8+48 hours after lymphatic chemotherapy was significantly increased(t=7.145,P＜0.05),while no significant changes of CD3+,CIM+,CD8+,CD(16+56)+were detected(t=1.782,1.151,1.184,0.955,P＞0.05),when compared with those 30 minutes before lymphatic chemotherapy.Conclusions Preoperative lymphatic chemotherapy is safe and can enhance patients'immunity in early stage.

Different human thyroid carcinoma cell lines were treated with all-trans retinoic acid(RA). RA could inhibit cell growth,improve iodide uptake and increase some thyroid specific genes and retinoid acid receptor(RAR)mRNA expressions in FTC-133 cells.However,RA had no effect in C643,HTH74 and XTC. UC1 cells.These findings indicate that different thyroid carcinoma cells display diverse responses to RA.

Objective To explore the effect of perioperative continuous use of aspirin on bleeding in laparoscopic anterior resection for rectal cancer (RC) in patients taking low dose aspirin.Methods The prospective study was conducted.The clinicopathological data of 96 RC patients taking low dose aspirin who were admitted to the Shengjing Hospital of China Medical University from September 2014 to September 2016 were collected.All the 96 patients were divided into the aspirin group (perioperative continuous use of aspirin) and non-aspirin group (discontinuation of aspirin at 7 days preoperatively and taking aspirin at 3 days postoperatively)by random number table.Laparoscopic anterior resection for RC was applied to patients by the same team of doctors.Observation indicators:(1) comparison of surgical and postoperative situations between the 2 groups;(2) follow-up situations.Follow-up using outpatient examination and telephone interview was performed to detect the postoperative survival of patients up to January 2017.Measurement data with normal distribution were represented as (x)±s.Comparisons between groups were evaluated with the t test.Comparisons of count data were analyzed using the chi-square test and Fisher exact probability.Comparison of ordinal data was analyzed using the nonparametric test.Results All the 96 patients were enrolled into the study,including 50 in the aspirin group and 46 in the non-aspirin group.(1) Comparison of surgical and postoperative situations between the 2 groups:96patients underwent successful laparoscopic anterior resection for RC,including 1 with conversion to open surgery and 95 undergoing laparoscopic anterior resection for RC,without perioperative death,postoperative blood transfusion and rcoperation.Cases with conversion to open surgery,operation time,volume of intraoperative blood loss,decreasing value of postoperative hemoglobin (Hb),time to anal exsufflation,peritoneal drainage volume from 1-3 days postoperatively,cases with postoperative hematoehezia,cardio-cerebrovascular complications and overall complications (including postoperative hematochezia and cardio-cerebrovascular complications),duration of hospital stay,hospital expenses,cases in stage Ⅰ,Ⅱ and Ⅲ of postoperative TNM stage,postoperative coagulation indexes of platelet,prothrombin time,international normalized ratio,prothrombin activity,activated partial thromboplastin time,thrombin time and fibrinogen were 0,(112± 18) minutes,(39± 18) mL,(4.3±2.8)g/L,(57±24)hours,(22±9)mL/d,6,0,10,(8.6±2.5)days,(6 739±481)yuan,11,35,4,(236±80) × 109/L,(12.7± 1.1) seconds,1.00±0.08,101％ ± 15％,(28 ±4) seconds,(15.5 ± 1.9) seconds,(3.2±1.0)g/L in the aspirin group and 1,(118±16)minutes,(38±22)mL,(3.5±3.0)g/L,(55±29)hours,(20±8)mL/d,4,1,8,(9.1±2.3)days,(6606±510)yuan,5,36,5,(211±49)×109/L,(12.5±0.7)seconds,1.00±0.06,103％±11％,(29±3)seconds,(15.3±1.7)seconds,(3.1±0.7)g/L in the non-aspirin group,respectively,with no statistically significant difference between the 2 groups (t =-1.737,0.204,1.416,0.380,1.365,x2=0.038,0.107,t=-1.082,1.322,Z=-1.370,t=1.850,0.978,0.872,-0.712,-1.291,0.311,0.585,P＞0.05).Ten patients with postoperative hematochezia in the 2 groups were cured,without special treatment.One patient in the non-aspirin group was complicated with deep venous thrombosis and then was cured by single anticoagulant drug.Two and 2 patients in the aspirin group were respectively complicated with urinary retention and urinary tract infection.One,1 and 1 patients in the non-aspirin group were respectively complicated with inflammatory intestinal obstruction,urinary retention and urinary tract infection,and then were cured by conservative treatment.(2) Follow-up situations:of 96 patients,95 were followed-up for 4-27 months,with a median time of 13 months.During the follow-up,3 patients died and 92 had survival.Conclusion The perioperative continuous use of aspirin cannot increase risk of bleeding in laparoscopic anterior resection for RC in patients taking low dose aspirin.

Background and purpose:The aim of this study was to analyze the prognostic factors in uterine adenocarcinoma and adenosquamous carcinoma treated with a combination of neoadjuvant chemoradiotherapy and surgery.Methods:Clinicopathologic data from 50 patients with stageⅠB2-ⅡA2 uterine cervical cancer were collected from the First Afifliated Hospital of Bengbu Medical College between Apr. 2005 and Oct. 2011. All patients underwent neoajuvant chemoradiotherapy, followed by radical hysterectomy and pelvic lymph node dissection. Before surgery, an intravenous chemotherapy was given. A particular vaginal brachytherapy was given to those with tumor diameter≥6 cm. The survival and recurrence in patients were analyzed retrospectively to investigate the prognostic factors. Results:In 50 patients withⅠB2-ⅡA2 uterine adenocarcinoma and adenosquamous carcinoma, 15 died during the follow-up period. The 2-year and 5-year progression-free survival rates were 80.12% and 72.24%, respectively, and median progression-free survival was 68 months. The 2-year and 5-year overall survival rates were 95.38% and 73.56%, respectively, and median overall survival was 80 months. Univariate analysis revealed that pelvic lymph node metastasis, cervical stromal invasion, parametrial infiltration, tumor diameter reduction <3 cm and advanced stage were the prognostic factors in patients with cervical cancer (P<0.05). Age, postoperative radiochemotherapy, lymphatic clearance involvement, FIGO stage, preservation of ovary and pathologic type were not associated with prognosis (P>0.05). Multivariate Cox proportional analysis revealed that pelvic lymph node metastasis and tumor diameter reduction after radiation and chemotherapy were the independent prognostic factors in patients with cervical cancer. Conclusion:The combination of neoadjuvant chemotherapy and surgery improves the resectable rate of patients withⅠB2-ⅡA2 uterine adenocarcinoma and adenosquamous carcinoma. Pelvic lymph node metastasis and tumor diameter reduction after radiation and chemotherapy are the independent prognostic factors in patients with cervical cancer.

Objective To elucidate the biocompatibility differences of 4 dialyzers with different membranes in maintenance hemodialysis (MHD)patients. Methods A total of 60 MHD patients were enrolled in the prospective,randomized,control,cohort study.In baseline,synthetic polysulfone(PS)membrane dialyzer was used in all the patients for at least 3 months.Then the patients were randomly divided into three groups:ployethersulfone(PES)membrane group,cellulose triacetate (CTA)membrane group,and synthetic polymethylmethacrylate(PMMA)membrane group.Study duration was 6 months.No dialyzer was reused.The biocompatibility markers were detected repeatedly at different time points and compared with each other in different dialyzer groups. Results The blood levels of high sensitive C reactive protein,interleukin-1β and interleukin-13 were not significantly different among different groups on every time point.However,the blood complements levels and WBC count were significantly different among four kinds of dialyzer.When the dialyzers changed from PS to PMMA membrane,C3a levels and WBC count changed significantly(P＜0.05).Moreover,the change of C5a level was significantly different between PES group and PMMA group on month 3(P＜0.05). Conclusion There are some differences of biocompatibiliy among different dialyzer membranes.

Objectives To investigate the clinical effect of hemoperfusion in severe juvenile dermatomyositis. Meth-ods Two patients with severe juvenile dermatomyositis, who accepted hemoperfusion treatment, were retrospectively analyzed. Results In these 2 patients, the hemoperfusion process were smooth. The muscle pain was reduced and the muscle enzymes were decreased. After hemoperfusion, one patient refused to continue treatment and the disease recurrent. The other patient con-tinued to accept the immunosuppressive therapy and eventually improved. Conclusions For juvenile dermatomyositis, hemo-perfusion was a safe and effective auxiliary treatment. It could be applied when the general treatment was invalid.

Objective To investigate the effects of ulinastatin (UTI) combined with magnesium isoglycyrrhizinate (MgIG) on the expression of transforming growth factor-β1 (TGF-β1) and connective tissue growth factor (CTGF) in lung tis?sue of rats with pulmonary fibrosis induced by bleomycin (BLM). Methods Ninety Wistar rats were randomly divided into five groups: BLM group, methylprednisolone (MTH) group, UTI group, MgIG group and UTI combined with MgIG (UTI+MgIG) group, n=18 for each group. The rat model of pulmonary fibrosis was established by injecting bleomycin through tra?chea in five groups. Twenty-four hours after treatment with BLM,rats were treated with normal saline every day in BLM group, and rats were treated by corresponding drugs in other groups. Six rats of each group were killed at the 7th,14th and 28th day respectively. The pathological changes of alveolitis and pulmonary fibrosis were evaluated by HE staining, and ex?pression levels of TGF-β1 and CTGF in lung tissues were detected by immunohistochemistry method. Results (1) Com?pared with BLM group, the degree of alveolitis and pulmonary fibrosis was reduced in other groups. There was significant dif?ference in alveolitis at the 7th and 14th day between UTI+MgIG group and BLM group. And there was significant difference in pulmonary fibrosis at the 14th and 28th day between UTI+MgIG group and BLM group (P<0.05). (2) Compared with BLM group, the expression levels of TGF-β1 and CTGF were decreased in other groups. In UTI+MgIG group, the expres?sion levels of TGF-β1 were significantly lower at the 7th and 14th day compared with those in UTI group and MgIG group, and which were significantly lower at the 28th day than those in MTH group, UTI group and MgIG group (P<0.05). The ex?pression levels of CTGF were significantly lower at the 7th day in UTI + MgIG group than those in UTI group and MgIG group, and which were significantly lower at the 14th and 28th day than those in MTH group, UTI group and MgIG group (P<0.05). Conclusion The combination of UTI and MgIG can alleviate alveolitis and fibrosis in BLM-induced pulmonary fibrosis rats, which might related with the down-regulation of TGF-β1 and CTGF expressions.

OBJECTIVETo explore the value of multidetector CT on aiding intraoperative judgement of serosal invasion of gastric cancer.

METHODSClinical data of 206 cases of gastric cancer undergoing radical surgery in the First Hosptial of China Medical University from August 2009 to June 2011 were analyzed retrospectively. Preoperative CT findings and intraoperative judgement of serosal invasion in gastric cancer were compared with pathological results in order to investigate their values.

RESULTSThe sensitivity and specificity of preoperative CT findings and intraoperative judgement of serosal invasion were 88.5%, 81.5% and 98.9%, 61.3%, respectively. The accuracy of preoperative CT in diagnosing serosal invasion was higher than that of intraoperative judgement, while the difference was not statistically significant (84.5% vs. 77.2%, P=0.060). The rates of serosal invasion of normal type, reactive type, nodular type, tendonoid type and color-diffused type were 0 (0/29), 2.5% (1/40), 40.5% (15/37), 59.2% (29/49), and 82.4% (42/51) respectively. The accuracy of preoperative CT in diagnosing serosal invasion of gastric cancer with tendonoid type was higher than that of intraoperative judgement, and the difference was statistically significant (61.2% vs. 87.8%, P=0.002).

CONCLUSIONSMultidetector CT plays an important role in aiding intraoperation judgement of serosal invasion of gastric cancer. For gastric cancer with tendonoid and color-diffused macroscopic serosal appearance, surgeons should pay attention to the value of preoperative CT findings.
