Objective To compare the efficacy and toxicity of in patients with advanced colorectal cancer. Methods Seventy-six patients were enrolled in this study.38 patients(treatment group)received chemotherapy regimen of sodium cantharidate 0 3mg,CF 200mg/m 2, and 5-Fu 375mg/m 2 intravenous infusion from the first day to the tenth day. 38 patients(control group)received chemotherapy regimen of CF 200mg/m 2 and 5-Fu 375mg/m 2 intravenous infusion from the first day to the tenth day. ALL patients underwent two cycles of the therapy at least. Results The efficacy of the treatment group and control group was 39 5% and 18 4% respectively, which had a significant difference. The hematologic toxicities in the treatment group, especially leukopenia and anemia, were significantly than those in the control group less. Conlusion The results indicated that sodium cantharidate combined with 5-FU and CF treatment of colorectal cancer had moderate activity and less toxicity, further clinical investigation of which should be performed.

Objective To evaluate the renal involvement and therapeutic effect on ANCA-associated vasculitis(ASV) . Methods Fifty-six cases were diagnosed as ASV from Oct 1997 to Mar 2001. Among them, 21 cases received renal biopsies. According to disease activity and severity, Use following treatment protocols were choosed: (1) double pulse therapy; (2) single pulse therapy; (3) oral prednisone and/or low dose of CTX; (4) blood purification technique and/or immunosuppressive therapy. Remission rate was also analyzed. Results 96. 4% of case suffered with renal involvement. 91. 1% with acute renal failure, 96.4% with severe renal failure, 98. 2% with multiple organs involvement. The mortality was 19. 6% and the remission rate 67. 9%. 12. 5% of cases lost follow-up. ConclusionsRenal involvement is common and serious in ASV patients. Individualized and early therapy, as well as valuable urgent renal biopsy are necessary. To those who have entered ESRD, immunosuppressive agents could be used to decrease the extra-renal complication.

Objective To investigate the effect of hypoxia on renal tubular cells and the mechanism of renal interstitial fibrosis. Methods Effect of chronic hypoxia on the proliferation, cell cycle and expression of TGF-?1 mRNA in cultured MDCK cells was examined. Quiescent cells were exposed to hypoxia (3%O2) or normoxia (18%O2) for 24, 48, 72 and 96 hours. At the end of each incubation, cellular proliferation and cell cycle were assessed by MTT method and flow cytometry, respectively. TGF-?1 mRNA level of cells were analyzed by semi-quantity RT-PCR. Results Exposure of MDCK cells to hypoxia induced a significant increase in proliferation and a significant decrease in the percentage of G0-G1 stage and a significant increase in the percentage of G2-M stage at 24, 48 and 72 hours. Meanwhile, TGF-?1 mRNA expression increased in a time-dependent manner as compared with normoxia group when MDCK cells were stimulated with 24, 48, 72 and 96 hours in hypoxia condition. Conclusion Chronic hypoxia-induced proliferation of MDCK cells is associated with increased expression of TGF-?1. Chronic hypoxia of renal tubular cells may be one of the causes of renal interstitial fibrosis.

Objective To investigate the expression of metastin and its significance in benign breast disease,normal breast tissue and breast carcinoma.Methods SP immunohistochemistry was used to determine the expression of metastin in 16 benign breast disease,12 normal breast tissue and 56 breast carcinoma.Results The positive rates of metastin in benign breast disease,normal breast tissue and breast carcinoma were 68.8%,75% and 30.4%,respectively.The expression of metastin in breast carcinoma was much lower than that in benign breast disease and normal breast tissue(P

Objective To investigated the inhibitory effect of an IgG-Fc region specific inhibitory peptide on the ANCA-accelerated apoptosis of neutrophils. Methods The peptide was prepared by solid-phase peptide synthesis and its biological activity was identified by rosette formation assay. ANCA was prepared from the sera of active Wegener's granulomatosis (WG) and microscopic polyangiitis (MPA) patients. Neutrophils isolated from the blood of healthy volunteers were primed with TNF-?(2 ng/ml) then incubated with ANCA. At different intervals(3, 6, 12, 18 hours) the neutrophils were harvested to assess the apoptosis by flow cytometric analysis of JC-1 staining, Sub-G1 population and fonnation TUNEL technique. Results Tg19320 bound tightly to human IgG dose-dependendy and inhibited statistically the rosette formation between SRBC-IgG and U937 cells(20.3% vs 53.2% ,P

Objective Intradialytic hypotension (IDH) is one of the common complications during hemodialysis,however its diagnostic criteria are highly controversial at present.In order to fully understand the prevalence of IDH in our center and figure out which diagnostic criteria is better for Chinese maintenance hemodialysis (MHD) patients,we choose several IDH definitions by reviewing published literatures and analyze their association with mortality.Methods The patients were recruited from Blood Purification Center of Ruijin Hospital undergoing hemodialysis during July 2012.Pre-,intra-and post-dialysis blood pressure were recorded.Patients' clinical characteristics,laboratory results and cardiac ultrasound results were collected.Based on several IDH definitions,we investigated the prevalence rate of IDH and its frequency among MHD patients.SPSS 23.0 was used to analyze data and conduct survival analysis.Results Totally 219 MHD patients underwent 16084 hemodialysis in 6 months.The prevalence rate,overall and individual frequency of IDH fluctuated between 45.21％-100.00％,4.64％-37.60％ and 0.00％-33.00％ respectively.For every IDH criteria,the patients were recruited into the group IDH(+) if they ever met the corresponding definition,otherwise the group IDH(-).Survival analysis found that IDH (the criteria of an absolute systolic blood pressure (SBP) ＜ 90 mmHg or with a decrease of SBP≥ 20 mmHg) could decrease the risk of patients' cardiovascular mortality but was not relevant to all-cause mortality.Further analysis showed these patients had better cardiac functions mainly reflecting in lower Pro-BNP (2880 ng/L vs 6909 ng/L),lower prevalence rate of left ventricular hypertrophy (52％ vs 83％) and higher left ventricular ejection fraction (65.0％ vs 62.5％) than IDH(-) patients.No correlation was found between other IDH criteria and mortality.Conclusions The prevalence rate,overall and individual IDH frequency of IDH are of high variability when diagnosed by different IDH criteria.All IDH episodes defined by our selected definitions are of no association with all-cause mortality.An absolute SBP ＜ 90 mmHg or with a decrease of SBP≥20 mmHg can decrease the risk of cardiovascular mortality due to their better cardiac function.Large scale researches should be conducted to find optimal IDH definition and explore the association of IDH and mortality.

Objective:To determine the prevalence of sarcopenia and explore related influencing factors of sarcopenia in maintenance hemodialysis (MHD) patients.Methods:MHD patients aged ≥18 years old and receiving therapies of ≥3 months from March 2019 to December 2019 in Blood Purification Centre of Ruijin Hospital Affiliated to Shanghai Jiao Tong University School of Medicine were retrospectively enrolled in this study. General data of the patients were collected. Grip strength was measured by the Jamar dynamometer and the chair stand was measured by a chair of standard height to assess skeletal muscle strength and appendicular skeletal muscle mass was measured by dual energy X-ray absorptiometry. Baseline data between MHD patients with and without myasthenia were compared. Logistic regression analysis method was used to analyze the influencing factors for sarcopenia in MHD patients.Results:A total of 125 MHD patients were enrolled, with 68 males (54.4%), age of (59.4±14.9) years and median dialysis age of 51.0(23.5, 101.0) months. Sarcopenia was diagnosed in 39 cases (31.2%). Compared with MHD patients without sarcopenia, age, tumor necrosis factor-α, von Willebrand factor (vWF) and proportion of using α ketones were higher, and serum carbondioxide combining power (CO 2CP), prealbumin, albumin and proportion of regular exercise were lower in MHD patients with sarcopenia (all P<0.05). Multivariable logistic regression analysis results showed that low CO 2CP ( OR=0.717, 95% CI 0.576-0.892, P=0.003), high vWF ( OR=1.037, 95% CI 1.016-1.058, P<0.001) and no regular exercise ( OR=0.309, 95% CI 0.118-0.810, P=0.017) were independent influencing factors of sarcopenia in MHD patients. Conclusions:The prevalence of sarcopenia in MHD patients is high. Low CO 2CP, high vWF and no regular exercise are independent influencing factors for sarcopenia in MHD patients.

Objective To investigate the effects of advanced oxidation protein products (AOPP) in type 2 diabetic ocular muscles palsy (DOMP). Methods 58 DOMP patients and 50 type 2 diabetes patients were included in the research. Hemoglobin A1c (HbA1c), blood glucose (FPG), fasting insulin (FINS) and triglycerides (TG), total cholesterol (TC), high-density lipoprotein (HDL), low-density lipoprotein (LDL) were measured and recorded. Homeostasis model assessment was performed to evaluate the status of insulin resistance (HOMA-IR), basal insulin secretion (HOMA-β) and the insulin sensitivity index (ISI). Serum AOPP was measured by enzyme linked immunosorbent assay. Unconditional logistic regression model was used to evaluate the influencing factors of DOMP. Results The DOMP group showed higher levels of plasma AOPP, TG, LDL, FPG, FINS, HbA1c and HOMA-IR, but lower levels of HDL, HOMA-β and ISI than those of the T2DM group. Unconditional logistic regression analysis revealed that AOPP was an independent risk factors for DOMP (OR =3.01, P = 0.002). Conclusion AOPP may be involved in the pathogenesis of DOMP. AOPP could be a useful indicator for monitoring the development of DOMP and for evaluating its severity.

Objective To explore the change of glyoxalase I in type 2 diabetic ocular muscles palsy (DOMP) and its associations with advanced oxidation protein products (AOPP) and oxidative stress. Methods 58 DOMP patients, 50 T2DM and 30 normal controls were enrolled in this study. Levels of blood lipids, fasting blood glucose, hemoglobin A1c, insulin, serum glyoxalase I, AOPP, malondialdehyde (MDA), superoxide dismutase (SOD) and total antioxidant capacity (T-AOC) were measured. Homeostasis model assessment was performed to evaluate the status of insulin resistance (IR). Results Levels of high-density lipoprotein cholesterol, SOD and T-AOC were positively correlated with glyoxalase I and inversely associated to AOPP. Levels of triglycerides , low-density lipoprotein cholesterol , fasting blood glucose , hemoglobin A1c , IR and MDA were negatively correlated with glyoxalase I and positively related to AOPP. AOPP had an inverse association with glyoxalase I (r = -0.823, P < 0.001). Multivariate regression analysis showed that serum levels of glyoxalase I (Sβ = 0.554) and AOPP (Sβ= -0.469) were influencing factors of groups. Conclusion Serum glyoxalase I levels were significantly decreased in DOMP and correlated with AOPP and levels of oxidative stress , which suggest that glyoxalase I could play crucial roles on the development of DOMP.

Objective To analyze the clinical features and pulmonary radiological findings of primary anti-neutrophil cytoplasmic antibody(ANCA)-associated vasculitis (AAV).Methods Clinical data of 271 ANCA positive primary AAV patients admitted in Shanghai Ruijin Hospital from January 2003 to November 2015 were retrospectively analyzed.Among 271 patients,there were 211 myeloperoxidase (MPO)-ANCA positive cases (MPO subgroup),52 proteinase 3 (PR3)-ANCA positive cases (PR3 subgroup),and 8 dual positive cases (dual subgroup) according to ANCA classification.The demography,clinical characteristics,pulmonary radiological manifestation and renal function were compared among three subgroups.Results MPO subgroup had more renal (x2 =4.968,P =0.026) and constitutional symptoms (x2.=8.901,P =0.003) than PR3 group,while PR3 group had more ENT symptoms (x2 =19.843,P ＜ 0.001),cough (x2 =6.623,P =0.010),hemoptysis (x2 =8.656,P =0.003),dyspnea (x2 =5.127,P =0.024),buccal and ocular mucosal symptoms (x2 =4.818,P =0.028) than MPO group.In lung radiology,interstitial manifestations were displayed more frequently in MPO than PR3 group (x2 =4.237,P =0.040),while pulmonary nodules was more frequent in PR3 than MPO group (x2 =4.503,P =0.034).Dual subgroup tended to have more nervous,respiratory and renal impairment.Renal function showed that MPO subgroup had higher creatinine (Z =-5.529,P ＜ 0.001),urea (Z =-4.646,P ＜ 0.001) and uric acid levels (Z =-2.331,P =0.020) than PR3 subgroup.Dual subgroup had higher creatinine (Z =-3.251,P =0.001) and urea (Z =-2.882,P =0.004) levels than PR3 subgroup,but there was no difference with MPO subgroup.Conclusion There are significant differences in both clinical and pulmonary radiological manifestations between the MPO and PR3-ANCA subgroup of primary AAV.
