Objective To observe effects of different concentrations of sevoflurane combined with propofol on recovery quality in patients undergoing partial hepatic resection.Methods Seventy-eight patients,aged 20-70 years old,selected for partial hepatic resection were randomly divided into three groups,26 patients in each group:total intravenous propofol anesthesia group (group T), propofol combined with 0.5 MAC sevoflurane anesthesia group (group S1),propofol combined with 1.0 MAC sevoflurane anesthesia group (group S2).Spontaneous respiration recovery time,recovery time,extubation time and modified Aldrete score of 9 time were recorded after operation.Modified OAA/S scores as well as modified Aldrete score at extubation immediate time (T1 )and 5 min (T2 ), 1 5 min(T3 ),30 min(T4 )after extubation were also recorded.Results Total amount of propofol in groups S1,S2 significantly less than group T and total amount of propofol in group S2 significantly less than group S1(P <0.05).The recovery time,extubation time,modified Aldrete score of 9 time in groups S1 and S2 were significantly shorter than group T (P <0.05).Modified OAA/S scores at T1 ,T2 and the modified Aldrete scores at T1 in both groups S1 and S2 were significantly higher than group T,while group S2 was significantly higher than group S1 (P <0.05).Conclusion Compared with total intravenous propofol anesthesia,both propofol combined with 0.5 MAC sevoflurane and propofol combined with 1.0 MAC sevoflurane anesthesia improves the recovery quality in patients un-dergoing partial hepatic resection,and the recovery time was decreased in propofol combined with 1.0 MAC sevoflurane anesthesia.

Objective To investigate and evaluate the detection and the variety of histology type constituent of the thyroid malignant tumor before and after universal salt iodization.Methods 1011 clinical pathological data of thyroid malignant tumor confirmed pathologically from 1961 to 2000 was retrospectively analyzed.The detection rate of thyroid malignant tumor,the constituent ratios of each histology type and the changes of age and sex distribution in main types of thyroid malignant tumor were determined.Results The total detection rate of thyroid malignant tumor after universal salt iodization (USI) (0.69%) were obviously increased compared with before universal salt iodization(0.46%,P40 years old) than before USI(≤40 years old).The incidence rates of thyroid malignant tumor in female patients were higher than male patients before and after USI.Conclusion The proportion and average age of thyroid malignant tumor increases after USI.The histological types of thyroid carcinoma have changes after USI:the proportion of PC increases obviously,the proportion of FC decreases accordingly.The average age of thyroid malignant tumor sufferers tends to increase and the peak ages of PC,FC and UC raise after USI.

Objective Little research has been done on the risk factor analysis of BK virus(BKV) infection in renal transplant recipients in Chinese population.The article aimed to investigate BKV infection and analyze its risk factors in renal transplant recipients in China.Methods Renal transplant recipients who had received the detection of BKV DNA in urine and blood samples in Nanjing General Hospital from June 2015 to July 2016 were selected, while the patients with uremia hemodialysis and healthy living donors were included as control group.According to the detection results of BKV DNA in urine and blood samples, renal transplant recipients were divided into BKV DNA positive group(n=89, positive urine or blood and urine BKV DNA) and BKV DNA negative group(n=359, negative blood and urine BKV DNA).Analysis was made on BKV infection in renal transplant recipients in order to investigate the effects of factors including clinical condition, postoperative complications and immunosuppressive regimen on BKV infection.Results The positive rate of BKV DNA in urine samples of renal transplant recipients was 19.9%, which was higher than those of patients with dialysis and healthy living donors(6.3% and 4.2% respectively, P<0.001).Multivariate logistic regression analysis showed BKV infection was associated with pulmonary infection(OR[95%CI], 3.468[1.227-9.802];P=0.019) , acute rejection (OR[95%CI], 2.645[1.142-6.127];P=0.023), and FK506 (OR[95%CI], 2.408[1.104-5.254];P=0.027).Conclusion The incidence of BKV infection in renal transplant recipients increases significantly.Pulmonary infection, acute rejection and FK506-based immunosuppressive regimen are risk factors leading to BKV infection.

Objective BK virus-associated nephropathy ( BKVAN) after kidney transplantation is a key factor that influence the prognosis of transplant kidney .To our knowledge , it is believed to be associated with immune suppression .We observed the cura-tive effect and influencing factorsof anti-rejection scheme that Leflunomide was administered instead of Mycophenolate Mofetil ( MMF) on transplant kidney BKVAN .. Methods This study included 15 kidney transplant recipients with pathologically confirmed BKVAN in Nanjing General Hospital of Nanjing Military Region form March 2007 to March 2013 .Leflunomide was administered instead of Myco-phenolate Mofetil ( MMF) .Serum creatinine level , renal allograft loss rate and side effects of leflunomide were monitored after medica-tion switch.The patients were divided into two groups , which were renal allograft loss group and renal allograft survival group , for fur-ther analyses . The differences between each groups in clinical characteristics as well as histochemical features of the transplanted kidneys were analyzed to determine the cause of renal allograft loss in patients with BKVAN . Results Six patients experienced renal al-lograft loss after switching to leflunomide and needed hemodialysis , and 9 patients had stable renal allograft function , renal allograft loss rate was 40.0%.Hyperuricemia occurred in 8 patients in the period before the medication switch and in 5 patients after the switch;a decrease in blood white cell orplateletcount was found in 2 patients during both periods;an increase in Alanine aminotransferase ( ALT) level occurred in one patient after the medication switch .There were no statistically significant differences in any of the above parame-ters before and after the medication switch.Compared to allograft survival group, serum creatinine level[(1.80 ±0.53)mg/dL vs (2.74 ±0.58)mg/dL, P=0.007], the number of B lymphocytes [(206.44 ±144.96) vs (439.67 ±267.77), P=0.047] and CD68[(588.44 ±271.80) vs (944.67 ±259.32), P=0.025] in renal allograft tissue were significantly higherin the allograft loss group. ConclusionLeflunomide is a safe and effective medication for BKVAN .Patients with significantly increased serum creatinine level might have a poorer prognosis .Significantly increased B lymphocytes and CD 68 cells in renal allograft tissue might indicate a poor prognosis.

Objective Sirolimus ( SRL) is a potent immunosuppressive drug used to prevent acute allograft rejection after re-nal transplantation.Nevertheless, the occurrence of proteinuria has recently been recognized among patients treated with SRL-based therapy.The aim of this study was to investigate the therapeutic effect of tripterygium wilfordii hook F ( T II) on proteinuria caused by SRL in renal transplant recipients who were treated by trilogy immunosuppressive therapy of sirolimus combined with mycophenolate and hormone. Methods 52 recipients were divided into 2 groups randomly:TⅡgroup (n=27) and valsartan group (n=25).The TⅡgroup was administered 1 mg/kg/d, and the valsartan group 80-160 mg/d for consecutive 12 months.Based on primary trilogy immu-nosuppressive therapy of sirolimus combined with mycophenolate and hormone, the dosage of sirolimus was adjusted according to the target concentration 6-10 ng/ml( ELASA approach) and mycophenolate was administered 750 mg twice per day, adjusting dosage ac-cording to the mycophenolate AUC 0-12 level(35-45 mg· h/L).The evaluation of therapeutic effect includes: complete remission, proteinuria decreased by>50%; partial remission, proteinuria decreased by 20% to 50%; ineffective, proteinuria decreased by<20%. Results During the 12 month follow-up, the total effective rates in the TⅡgroup and the valsartan group were 95.2%and 86.7%respectively, in which the TⅡ group decreased more significantly (P<0.01).The total cholesterol level and triglyceride level in TⅡgroup were obviously lower than those in valsartan group(P<0.01). The total cholesterol level and triglyceride level in valsartan group increased ([6.60±0.2]mmol/L vs [7.11±1.13]mmol/L, [2.47± 1.48]mmol/L vs [2.49±0.32] mmol/L).The serum protein level in TⅡ group was obviously higher than that in valsartan group ([41.1±1.2]g/L vs [37.9±4.2]g/L, P<0.05).At 3 month, 6 month and 12 month follow-up, the average serum creatinine levels in TⅡgroup were obviously lower than those in valsartan group ([1.5±0.4]mg/dl vs [1.6±0.3]mg/dl, P<0.05), ([1.3±0.3]mg/dl vs [1.8±0.5]mg/dl, P<0.05), ([1.1±0.4]mg/dl vs [2.1±0.5]mg/dl, P<0.05).The incidence rate of adverse reaction in valsartan group was obviously greater compared with TⅡgroup( P<0.05) . Conclusion Both tripterygium wilfordii multiglycosides and valsar-tan can reduce proteinuria caused by SRL in renal transplant patients,while the application of TⅡhas more remarkable effect.

Objective To evaluate the efficacy of rescue treatment for recurrent esophageal cancer after radical esophagectomy, and to provide insights into the development of comprehensive treatment for esophageal cancer.Methods The clinical data of 218 patients who were confirmed with recurrent metastatic esophageal cancer after R0 resection and received rescue treatment in our hospital from 2004 to 2014 were retrospectively reviewed.The survival rate was determined by the Kaplan-Meier method.Univariate and multivariate prognostic analyses were performed using the log-rank test and Cox proportional hazards model, respectively.Results The median post-recurrence follow-up time was 53 months.The 1-and 3-year overall survival (OS) rates after recurrence were 57.2% and 24.4%, respectively.Among the 163 patients with local recurrence, the 1-and 3-year OS rates were 70% and 42% for patients treated with chemoradiotherapy (n=40), 55% and 24% for those with radiotherapy alone (n=106), and 23% and 8% for those with supportive therapy (n=13)(chemoradiotherapy vs.radiotherapy alone P=0.045, radiotherapy alone vs.supportive therapy P=0.004;none of the patients who were treated with chemotherapy alone survived for one year or more).Univariate analysis showed that N staging, TNM staging, and post-recurrence rescue treatment regimen were independent prognostic factors for esophageal cancer (all P=0.001).On the other hand, multivariate analysis indicated that only rescue treatment regimen was the independent prognostic factor for esophageal cancer (P=0.013).Conclusions Rescue chemoradiotherapy or radiotherapy alone can bring significant survival benefits for patients with recurrent and metastatic, especially locally recurrent, esophageal cancer following radical esophagectomy.

OBJECTIVE: To study the change of laryngeal carcinoma cell apoptosis before and after radiotherapy. METHOD: Living tissue of diseased region obtained from 27 cases of laryngeal carcinoma before and during radiotherapy 10, 30 and 60 Gy were used in this study. With terminal deoxynucleotidyl transferase mediated dUTP biotin nick end labeling (TUNEL), the spontaneous and radiation-induced apoptotic rate (AR)were examined. RESULT: The AR of living tissue of laryngeal carcinoma before and during radiotherapy 10, 30 and 60 Gy were (21.0 +/- 0.7)%, (60.0 +/- 1.5)%, (42.0 +/- 1.3)%, (25.0 +/- 1.9)%, respectively. The radiation-induced apoptotic rate was significantly higher than that of spontaneous apoptotic rate (P< 0 . 5). In laryngeal carcinoma, spontaneous apoptosis was positively correlated with the radiation-induced apoptosis. CONCLUSION Detecting of AR of laryngeal carcinoma cells before and during radiotherapy may be helpful to predict the sensitivity of radiotherapy in laryngeal carcinoma patients.

Objective To investigate the epidemiology characteristics of crawfish related rhabdomyolysis (RM) in Nanjing, 2016.Methods Outpatient and inpatient electronic medical system of 21 hospitals in Nanjing during 2016 were retrospectively searched, and all the patients diagnosed with RM were selected. The patients with none crayfish-related RM was excluded. The epidemiology characteristics were depicted. The geographic information system (GIS) was used to collect, manage and analyze the spatial data, to visualize it, to analyze the spatial distribution features of the disease, and to explore the cause of disease prediction. GeoDa 1.8 software was used to analyze the global and local spatial auto-correlation.Results A total of 1183 patients with crawfish related RM were initially screened, excluding 59 patients with RM caused by trauma, severe exercise, heat stroke, myositis, poisoning, drugs, and genetic diseases, and 1124 patients were enrolled. The proportion of men was 36.48% (410/1124) with an incidence of 12.54/100 thousands; while of women was 63.52% (714/1124) with an incidence of 21.86/100 thousands. The median age at onset was 34 (28, 43) years. From July to August, the incidence of crawfish related RM was the highest, accounting for 96.53% of the total number of cases. The top four incidence areas were Pukou (41.54/100 thousands), Jianye (25.94/100 thousands), Qixia (25.73/100 thousands), Gulou (25.04/100 thousands), all of which were adjacent to the Yangtze River. Global spatial autocorrelation analysis showed: MoranI = 0.427,Z = 2.646,P = 0.003, suggesting that the crawfish related RM had positive spatial autocorrelation. The results showed that the spatial structure of crawfish related RM existed in Nanjing in 2016. Local spatial autocorrelation analysis showed that the high-high concentration areas were Pukou, Jianye and Liuhe. The incidences of above three areas which were the Nanjing section of the lower reaches of the Yangtze River flowed through the region and surrounding areas were higher than the overall incidence of Nanjing.Conclusion The prevalence of crawfish related RM in Nanjing during 2016 had an obvious region-concentrated character and global spatial autocorrelation with the high prevalent regions mainly concentrated in the urban areas adjacent to the Yangtze River.

Objective: To evaluate the efficacy and safety of bortezomib in kidney transplant recipients with chronic active antibody-mediated rejection (cABMR). Methods: A retrospective study wad conducted in patients(n=136)fulfilling the Banff 2017 criteria for cABMR from January 2004 to July 2017, including 29 patients bortezomib group and 97 patients in control group. Identified cABMR patients were dichotomized into bortezomib and control groups with a 1∶1 match using the propensity score matching method. The primary outcome was initiation of replacement therapy or an estimated glomerular filtration rate(eGFR)declined to <15 ml·min^-1·(1.73m²)^-1. The prognosis and adverse reactions of two groups were analyzed and evaluated. Results: No significant inter-group differences existed in age, sex ratio, immunosuppressive regimen, allograft age, serum creatinine, eGFR, urine protein, serum albumin, hemoglobin or HCV positive rate(all P>0.05). There were no significant inter-group differences in Banff scores (g, i, t, v, ah, mm, ci, ct, cv, ptc, c4d, all P>0.05). The median survival for bortezomib group and control group was 40.7 months and 36.9 months respectively. No statistically significant difference in graft survival between the two groups was observed(P=0.83), even after propensity score adjustment(P=0.29). The incidence of nausea, diarrhea and thrombocytopenia in bortezomib group was higher than those in control group (P<0.05). Conclusions Bortezomib does not seem to improve the prognosis of cABMR while is associated with higher incidence of adverse reactions.
