Purpose:To improve the diagnostic accuracy of gastric submucosal tumor whose endoscopy was negative. Methods:Six cases of gastric submucosal tumor with “negative” results of endoscopy were analyzed. Results:Before operation 3 were recieved by medicinal management, 5 were diagnosed as malignant tumor by CT, 2 were shown to be tumor by ultrasound. There were 3 gastric lymphoma, 1 gastric adenocarcinoma, 1 gastric Schwannoma and 1 gastric leiomyosarcoma confirmed by postoperational pathologic diagnosis. Conclusions:If suspicion remains in endoscopy diagnosis, procedure should involve careful physical examination, CT, B US, GI and so on to improve the diagnostic accuracy. [

Objective To study the differences between renal clear cell renal cell carcinoma (CCRCC)and angiomyolipoma (AML)with minimal fat,whose size were both smaller than 3cm and the lesions center were both located outside the renal contour. Methods 6 cases of CCRCC and 18 cases of AML with minimal fat were analyzed retrospectively.All the lesions were confirmed pathologically.The morphological characteristics,plain and enhanced CT values were obtained for compare.Results The lesion length diameter,morphology,the early excretory phase CT value and the pattern of enhancement were not significant different between the two groups (P>0.05).There was significant difference in the focal cystic and necrotic between CCRCC group and AML group (P<0.05).Plain scan density,enhanced uniformity,pseudo capsule sign,plain CT values,medullary junction CT value and the pattern of enhancement from medullary junction phase were statistically different between those two groups (P< 0.001).Conclusion The focal cystic and necrotic,plain scan density, enhanced uniformity,pseudo capsule signs,plain CT values,the cortex and medullary junction CT value and the enhanced amplitude were very important role in differential diagnosis of CCRCC and AML with minimal fat.

Objective To investigate the diagnosis and treatment of the posterior fossa solid hemangioblastomas (PFSHs).Methods The data of 23 patients with PFSHs verified by surgery and pathology were analyzed retrospectively.Results Nineteen cases were diagnosed with PFSHs before surgery.Total tumor removal was achieved in 22 patients.No case died of operation.A follow-up time was 0.33 -9.00 (2.96 ±2.73) years,20 patients returned to work,1 patient had self-handling living,and 2 patients died.Conclusions MRI and digital subtraction angiography are major preoperatively diagnostic modalities for PFSHs.PFSHs is still a kind of challenging neoplasms.Applicating special microsurgical technique and improving the operative manipulation can improve the surgical efficacy.

Objective To investigate the effect of sleeve gastrectomy on the intestinal barrier of obesity rats fed with high-fat diet.Methods Thirty obesity rats fed with high-fat diet were randomly divided into three groups including common diet group (CD,n=10),sham operation group (SO,n=10) and sleeve gastrectomy group (SG,n=10).The lactulose/mannitol ratios (L/M) in 24-hour urine and endotoxin in portal vein were evaluated four weeks after surgery.The levels of tight junction proteins including claudin-1 and occludin in intestinal mucosa were analyzed by western blot.Results The body weight of SG group was significantly decreased than those of CD group (P<0.001) and SO group (P<0.001) four weeks after surgery.The L/M ratio in 24-hour urine of SG group was significantly lower than those of CD group (P<0.001) and SO group (P<0.01).The endotoxin level in portal vein of SG group was significantly lower than those of CD group (P<0.01) and SO group (P<0.05).The claudin-1 level in intestinal mucosa of SG group was significantly higher than those of CD group (P<0.001) and SO group (P<0.01) four weeks after surgery.The occludin level in intestinal mucosa of SG group was significantly higherthan those of CD group (P<0.001) and SO group (P<0.001).Conclusions Sleeve gastrectomy can reduce body weight,L/M ratio in 24-hour urine and endotoxin level in portal vein of obesity rat fed with high-fat diet and increase the levels of claudin-1 and occludin in intestinal mucosa.

ObjectiveTo explore the role of parameters of organ function during heat stroke (HS) on the prognosis, and to form the treatment strategy through an analysis of parameters of organ function during HS. Methods A retrospective study was conducted. Thirty-seven patients with HS (HS group) and 54 patients with mild-to-moderate stroke (stroke group) admitted to Zhejiang Xiaoshan Hospital from 2011 to 2014 were enrolled. The experimental results of organs function indicators for patients were recorded including:① cardiac markers:troponin I (TnI);② myocardium zymogram: creatine kinase (CK), MB isoenzyme of creatine kinase (CK-MB), lactate dehydrogenase (LDH), and aspartate aminotransferase (AST);③ renal function indexes: blood urea nitrogen (BUN), uric acid (UA), and serum creatinine (SCr);④ electrolyte: serum K+, Na+, and Cl-;⑤coagulation function: prothrombin time (PT), international normalized ratio (INR), activated partial thromboplastin time (APTT), thrombin time (TT), fibrinogen (FIB), and D-dimer;⑥ blood gas analysis: pH value, arterial partial pressure of carbon dioxide (PaCO2), base excess (BE), standard bicarbonate (SB), and actual bicarbonate (AB);⑦ routine blood test: blood platelet count (PLT);⑧ hepatic function: alanine aminotransferase (ALT). Abnormal rates of laboratory parameters of 37 HS patients were statistically analyzed. Various laboratory parameters of organs function as well as the initial value and extreme value (maximum or minimum value) during treatment of CK and PLT in HS patients were compared between two groups.Results The abnormal rates of 37 HS patients were more than 70%, including incipient value of TnI, CK, LDH, AST, serum Na+, ALT, D-dimer, PaCO2, AB, maximum value of CK, and minimum value of PLT, the abnormal rates being 73.0%, 70.3%, 81.1%, 78.4%, 78.4%, 70.3%, 70.3%, 70.3%, 75.7%, 81.1%, 75.7%, respectively. The abnormal rates of other parameters were less than 70%. There were significant differences in incipient value of TnI, CK, LDH, AST, serum K+, serum Na+, D-dimer, and PLT between HS group and mild-to-moderate stroke group [TnI (μg/L): 0.087 (0.026, 0.306) vs. 0.007 (0.004, 0.110),Z = -7.017,P = 0.000;CK (U/L): 392.30 (287.60, 524.10) vs. 137.10 (106.33, 607.80),Z = -7.930,P = 0.000; LDH (U/L): 317.98±122.74 vs. 207.85±57.71, t = 1.678,P = 0.000; AST (U/L): 94.90 (52.80, 155.80) vs. 26.10 (18.13, 317.40),Z = -6.157, P = 0.000; serum K+ (mmol/L): 3.46±0.65 vs. 3.86±0.57,t = 1.662,P = 0.001; serum Na+ (mmol/L): 129.75±7.34 vs. 138.79±4.26,t = 1.674,P = 0.000; D-dimer (mg/L): 2.53 (0.63, 6.00) vs. 0.30 (0.21, 9.71),Z = -5.084, P = 0.000; PLT (×109/L): 144.62±86.14 vs. 219.48±64.76,t = 1.669,P = 0.000]. There were also statistically significant differences in the initial value and extreme value of CK and PLT between HS group and mild-to-moderate stroke group [CK (U/L): 392.30 (287.60, 524.10) vs. 721.50 (546.30, 964.10),Z = -6.351,P = 0.000; PLT (×109/L):132.40±82.55 vs. 68.24±44.62,t = 1.688,P = 0.000].Conclusions HS can impair several organs and systems, having complications, and it is a heavy insult for body. Increasing of CK and decreasing of PLT has some value to assess illness changes. It is helpful of laboratory results for doctors to estimate complications on time.

Objective To evaluate the effect of technical improvement of radical retropubic prostatectomy (RRP) for patients with localized prostatic cancer. Methods RRP was performed in 32 cases (mean age,68 years) of prostatic cancer at clinical T 1 and T 2 stages.Technical improvements included extensive lymph node clearance,protection of the neurovascular bundle,suture and ligation of the dorsal vein complex,preservation of the distal prostatic urethra,and intussusception of the bladder neck. Results The mean operative time was 3.5 h.The mean blood loss was 450 ml;blood transfusion was conducted in 17 cases.Postoperative pathologic findings revealed tumor confined disease in 30 cases,positive surgical margin in 1, and lymph node metastasis in 1.All the patients survived and were followed up for a mean of 22 months (range 8 to 48 months),with PSA

Expressions of interleukin-6 (IL-6) and its receptor (gp80、gp130) in 8 patients with Graves' disease (GD) were compared with those in 8 euthyroid patients with nodular goiter or benign thyroid adenoma. The thyroid tissues of GD expressed significantly higher IL-6 mRNA, gp130 mRNA and IL-6 protein than those of the control group, suggesting that activated IL-6/gp130 signal pathway in the thyroid tissue may contribute to the pathogenesis of GD.
