More and more studies suggest that endocrine-metabolic diseases and liver diseases influence each other. Endocrine-metabolic diseases may lead to abnormal liver function, and liver diseases are found also to cause disturbance of endocrine-metabolic system.

Objective To investigate the effects of chemokine antagonist,Met-RANTES,on the acute rejection of islet allograft in the rat model.Methods According to the different treatments,rats were divided into 2 group: control group,allogeneic islet transplant untreated;experiment group,allogeneic islet transplant treated with Met-RANTES(200 ?g/day, i.p) for 7 days post-operation.The survival time of rat of islet transplant and blood sugar were recorded,and the pathological changes of islet allograft were observed.Scintillation counter was used to count the count per min(cpm) of monocytes.Flow cytometry was used to detect the ratio of CD4~+/CD8~+ phenotypes and CCR5 expression of peripheral blood lymphocytes.Results The mean survival time of islet allograft in experiment group was(23.0)?(10.5) days,obviously longer than in the control group((3.8)?(4.5) days,P

Objective To investigate the inhibitory effects of Argatroban on the instant bloodmediated inflammatory reaction(IBMIR)after islet transplantation.Methods Rat islets were isolated and purified rat islets,and were divided into blank control group,control group and experimental group.In the control group,the blood and the islets were directly mixed,and in the experimental group the Argatroban was added to the mixture based on the control group.while the blank control group was added with blood alone without the islets.Each group was reacted at 37℃for 60min,and then the content was filtered through trap valve of 70 μm.The residual thrombus and tissues were filtered by the trap valve in both the experimental and control groups,detected by the thinprep cytologic test(TCT),and the filtrate received blood routine test,and the function of islet was determined using insulin releasing test.Results The number of blood platelets,white blood cells,mononuclear cells,and lymphocytes percentage in the experimental group were significantly higher than in the control group after 60 min(P＜0.05).Under the environment of the high and low concentrations of glucose,the insulin release in experimental group was significantly increased as compared with the control group,and the insulin release index of former was 2.25±0.18,significantly higher than that of the latter 3.36±0.18(P＜0.05).The residual thrombus and tissues had few islet cells in the control group,the structure was damaged seriously,the capsule was not intact,and there were a large mumber of micro-thrombosis around the islets formed by red blood cells.But there were a large number of islet cells in the experimental group.the structure was intact in a mass,and no obvious micro-thrombosis around the islets was found.Conclusion Argatroban can effectively inhibit IBMIR in vitro,and alleviate the damage to the islet cells.

Objective To evaluate the diagnosis and treatment of vipoma based on our experience on 4 cases.Method Clinical manifestations,laboratory examination,imaging features,surgical findings,and pathology of 4 patients with vipoma admitted in our hospital from 1991 were discussed.Results Watery diarrhea and hypokalemia were the main clinical manifestations.Hepatic metastasis OCCurred in two patients.Tumor located in the head of the pancreas in one case.Two tumors were shown in the pancreatic body and one tumor was in the pancreatic tail.Resection of tumor and hepatic metastatic lesions with repeat resection of metastases Was performed in 1 patient.Resection of the pancreatic body and tail was done in one patient.Pancreatoduodenectomy Was performed in one patient.Laparotomy only was done in one patient because of invasion of the superior mesenteric vein and duodenum.Conclusion Typical symptoms play an important role in the diagnosis of vipoma.Hepatic metastasis is common.Surgery is the most effective means for treatment.

Objective To investigate the correlation and significance of cyclooxygenase-2 (COX-2)and the breast cancer resistance protein (BCRP) expressions in non-Hodgkin lymphoma(NHL). Methods Ten patients with reactive lymph nodes (RLN) were considered as a control group. Compared with β-actin as internal control, the BCRP mRNA expressions of 61 NHL samples and 10 lymph tissues in control group were detected by semi-quantitative revere transcription polymerase chain reaction (RT-PCR) assay, while the expressions of COX-2 protein of the above specimens were detected by SP immunohistochemistry. Results The positive rates of COX-2 and BCRP in NHL were 50.8 %(31/61) and 45.8 % (28/61), respectively , and were higher than those in the control group (P ＜0.05). The expression of COX-2 was statistically positive correlated to that of BCRP (X2 =8.795, r=0.355, P＜0.05). The expressions of COX-2 and BCRP were not correlated to clinical and pathological factors, such as age, sex, IPI, LDH, β2-microglobulin level and Ann Arbor stage, however, the expression of BCRP was statistically correlated to chemotherapy efficacy.Conclusion BCRP may be involved in multi-drug resistance (MDR) of NHL, so it may contribute to the assessment of chemotherapy and prediction of NHL. Since there is a strong correlation between COX-2 expression and MDR in NHL, the application of COX-2 inhibitors may enhance sensitivity of chemotherapy.

The application of resonance charging circuit to electro-hydraulic impulse apparatus for treating wastewater is introduced in this paper.The circuit permits the graduating increase of current without influence from time.The unique change of voltage on capacitor is favorable for the recovery of electric strength of electro-hydraulic impulse apparatus.The theory and design method of resonance charging circuit are provided.

In this experiment we used the model of the orthotopic liver transplantation with three cuff technique in rats.In treated group,coenzyme Q_(10) was injected intravenously into donor rats before donor hepatectomy.At the 4th hour after transplant,the activity of superoxide dismu- tase (SOD) and the level of lipid peroxidation (LPO) both in the blood and in the liver tissue were measured,meanwhile,the specimens of the grafted liver tissue were sent for microscope and elec- tromicroscope studies.The results showed:(1) The activity of SOD in treated group were higher than that in control group (P

Objective To explore the surgical method and effects of posterior expansive open-door laminoplasty extended to C1,2 levels.Methods 16 cervical spinal stenosis patients with cervical myelopathy were posterior cervical surgery in our hospital from February 2013 to September 2015,including 11 males and 5 females;aged 51-76,average 62.8.4 cases merged C1spinal stenosis,the line which operated by C1～7 spinal posterior open-door expansion of the forming with mini titanium fixation;12 cases merged C2 spinal stenosis,which had the operation of C2～7 posterior open-door laminoplasty with Micro Titanium fixation plate.According to the patient imaging data to assess the stability of the cervical spine,and spinal cord compression fixation position before and after their surgery evaluated;the preoperative and postoperative pain using visual analog scale (VAS);application Japanese Orthopaedic Association (JOA) score spinal cord score was used to evaluated spinal cord function,and calculates the rate of improvement of neurological function;surgery patients before and after application Frankel grading was used to evaluate neurological function.Results All patients were followed up,for an average of 11.58 months (2-33 months).16 patients showed no loosening,fracture fixation and related complications,C1,2 showed no instability;cerebrospinal fluid surrounding the spinal cord with in the C1-7 range of the signal on MRI T2WI showed continuous recovery;preoperative VAS score was 6.7 points,postoperative VAS score was 1.8 points;the first 16 cases of patients with preoperative JOA score average (8.3± 1.6) points,postoperative JOA score was (14.6±1.4) points,postoperative neurological improvement rate was 91.6％;Frankel grade C before operation and grade E in postoperation;postoperative follow-up neurological improvement rate excellent 7 cases,good 7 cases,general 2 cases.Conclusion Treatment of cervical spinal stenosis combined with cervical myelopathy may use a C 1-7 posterior spinal expand within the single door molding fixation with mini titanium plate,which can release the compression of the cervical spinal cord nerve and reconstruct a stable structure of posterior of cervical spine.
