Objective: To analyze chromosome aberrations in bladder transitional cell carcinoma with exfoliated cells, and to evaluate the clinical value of fluorescence in situ hybridization (FISH) in bladder cancer. Methods: FISH was performed using centromeric probes of 3, 7, 17 and locus probe of p16 to examine chromosome aberrations of exfoliated cells of 56 bladder cancer patients and 20 healthy controls to analyze the correlation of chromosome aberration with the pathological features of bladder cancer. The urine cytology of the 56 bladder cancer patients was performed. Results: The rates of aneuploidy of chromosomes 3, 7, and 17 were 58.9%, 39.3%, 58.9% and 75.0% for aberration of p16 in exfoliated cells from the 56 bladder cancer patients. All of the aberrations had no correlation with tumor stage (P>0.05). The aberrations of chromosomes 3, 7, and 17 were significantly correlated with pathological grade (P<0.05). The sensitivity of the 4 chromosome probes for detecting bladder cancer was 80.4%. The detection rate of FISH was obviously higher than that of udne cytology. Conclusion: Chromosome aberration is correlated with the growth of bladder cancer. The detection of FISH has significance for early di-agnosis, prognosis evaluation, and recurrence monitoring of bladder cancer.

ObjectiveTo investigate the etiology, diagnosis and choice of treatment for massive hemobilia. MethodsA retrospective analysis was made on the clinical data of 20 patients with massive hemobilia treated from August 1998 to August 2008. ResultsInitially conservative therapy was used on 20 patients and bleeding stopped in 4 patients. For the seven patients who were treated with hepatic artery angiography and embolization, bleeding stopped in 6 patients. 10 patients were treated by operation and bleeding stopped in all these patients. No patient died in this series. ConclusionsHepatic artery angiography and embolization should be used to treat patients with massive hemobilia. Surgery should be offered if conservative therapy and hepatic artery embolization fail.

OBJECTIVETo determine the role of zinc finger protein 1 (ZEB 1) in liver fibrosis and in regards to expression of the tumor growth factor-beta (TGFb) signaling factor using a rat model system.
METHODSSprague-Dawley rats were randomly divided into a normal (control) group, liver fibrosis (model) group and a liver fibrosis + therapy (ZEB1 intervention) group. The model group and the ZEB1 intervention group were given intraperitoneal injections of dimethylnitrosamine (DMN) for the first 3 days of each week over a 7-week period; starting at week 5, the ZEB 1 intervention group was started on a routine of every other day tail vein injections of recombinant ZEB1. During this 7-week period, the control group was given intraperitoneal injections of 0.9% NaC1 alone on the DMN schedule. Liver tissues were collected for pathological examination (with hematoxylin-eosin and Masson staining) and for detection of TGFb1 and ZEB 1 expression (by RT-PCR and western blotting). Measurement data were compared between groups using the single-factor analysis of variance test, followed by the least significant difference LSD test. Count data were analyzed by Fisher's exact test.
RESULTSThe model group's liver tissues showed degeneration and necrosis, as well as obvious fibrous septa accompanied by pseudo lobules. The ZEB 1 intervention group's liver tissues showed a significantly higher degree of fibrosis (x²=21.63, P=0), with more coarse fiber cords. The expression of ZEB1 and TGFb1 was significantly higher in the model group than in the control group (both P less than 0.05). However, the ZEB 1 intervention group showed the highest levels of ZEB 1 and TGFb1 expression (vs. model group, P less than 0.05).
CONCLUSIONZEB 1 may promote the development of liver fibrosis in rats through a mechanism involving the TGFb/Smad signaling pathway.

Objective:To analyze the feasibility, safety and clinical efficacy of laparoscopic side-to-side jejunoileal anastomosis in the treatment of non-obese type 2 diabetes patients (BMI≤32.5 kg/m 2). Methods:The clinical data of 135 patients who underwent laparoscopic side-to-side jejunoileal anastomosis at our hospital from Jan 2018 to Oct 2018 were retrospectively analyzed. They were followed up for 12 months until the end of Oct 2019. SPSS software was used to compare patients′ fasting blood glucose, glycosylated hemoglobin, c-peptide, insulin, body weight, BMI with the values after 12 months of the surgery, and then evaluate factors affecting the prognosis.Results:135 patients successfully completed laparoscopic side-to-side jejunoileal anastomosis without conversion to open surgery. After 12 months of the operation, the patients′ fasting blood glucose was (5.80±0.18)mmol/L, glycosylated hemoglobin was 5.9%±0.4%, fasting c-peptide was(1.32±0.21) nmol/L, and fasting insulin was (42±54) mU/L ( t=10.654, 12.657, 11.214, 10.698, all P<0.05). The body weight was (72.4±9.9)kg, BMI was( 25.6±2.8)kg/m 2, and the difference was not statistically significant ( t=7.658, 6.958, P>0.05). In patients with preoperative glycosylated hemoglobin controlled below 8% and the duration of T2DM less than 10 years, the chances being cured was better than that of those with glycosylated hemoglobin>8% and the medical history >10 years. Conclusion:Laparoscopic side-to-side jejunoileal anastomosis in the treatment of non-obese type 2 diabetes is effective, safe and reliable.

Objective:To investigate the therapeutic effect of human umbilical cord mesenchymal stem cells (MSCs) on psoriasis-like mouse models induced by imiquimod and the underlying mechanisms.Methods:Eighteen C57BL/6 mice were randomly and equally divided into vaseline group, model group and treatment group according to a random number table. The mice in the model group and treatment group received topical treatment with 5% imiquimod cream at a dose of 62.5 mg once a day for 6 consecutive days on the shaved back, and those in the vaseline group received the treatment with the same amount of vaseline ointment; the mice in the treatment group were injected with 1.5×10 6 human umbilical cord MSCs via the caudal vein on days 1 and 4. The severity of skin lesions on the back of the mice was assessed everyday according to the psoriasis area and severity index (PASI) . Twenty-four hours after the last treatment, that is, on day 7, blood samples were taken, and the mice were sacrificed. The dorsal skin tissues were resected and subjected to hematoxylin and eosin (HE) staining. A single cell suspension of the resected spleen was prepared, and flow cytometry was performed to detect the Th1 and Th17 cell subsets in the spleen cells. Enzyme-linked immunosorbent assay was conducted to detect serum levels of cytokines interleukin (IL) -17A and tumor necrosis factor (TNF) -α. One-way analysis of variance was used for comparisons among groups, Tukey test for multiple comparisons, and repeated measures analysis of variance for the analysis of changes in the PASI score over time. Results:On day 7, there was obvious scaly erythema on the back of the mice in the model group, and the skin thickness and number of infiltrating inflammatory cells were significantly higher in the model group (78.73 ± 23.11 μm, 36.16 ± 2.95 cells/mm 2) than in the vaseline group (13.28 ± 4.57 μm, 13.33 ± 1.15 cells/mm 2, q=19.25, 7.21, respectively, both P < 0.001) . The treatment group showed significantly decreased PASI score, epidermal thickness and number of infiltrating inflammatory cells compared with the model group (all P < 0.001) . The percentage of Th17 cell subsets in the spleen cells and serum level of TNF-α were significantly lower in the treatment group than in the model group (both P < 0.05) . There were no significant differences in the spleen weight, spleen index, spleen cell count, Th1 cell percentage or serum IL-17A level between the treatment group and the model group (all P>0.05) . Conclusion:Human umbilical cord MSCs can effectively alleviate skin inflammation induced by imiquimod in the psoriasis-like mouse models, likely by inhibiting Th17 cell formation and TNF-α expression.
