Objective To study the therapeutic effect of EUS-guided biliary drainage (EUS-BD) on patients with malignant obstructive jaundice when ERCP failed.Methods From January 2014 to January 2016,all patients with malignant obstructive jaundice during hospitalization underwent EUS-guided biliary drainage (group A,36 cases) or PTCD treatment (group B,30 cases) by draw after failed ERCP.Operation success rate,liver function recovery time,complication rates,length of hospital stay and hospital costs were observed and compared.Results There was no significant difference in the operation success rates between two groups [94.44％ (34/36) VS 86.67％ (26/30),P＞0 05)].And there were significant differences in liver function recovery time (25.79± 6.48 d VS 30.24 ± 8.49 d),incidence of complications [5.56％ (2/36) VS 23.33％ (7/30)],length of hospital stay (21.54±4.73 d VS 25.68 ± 8.56 d) and hospitalization costs (23.5±8.4 thousand yuan VS 32.8±6.5 thousand yuan,P＜0.05).Conclusion EUS-guided biliary drainage could be the first option for its noninvasiveness and efficacy,when ERCP failed in patients with malignant obstructive jaundice.

Objective To investigate the effect of Jinqi Jiangtang tablet on the activation of T helper type 17 (Th17) and the expressions of interleukin (IL)-17 and IL-23 in kidney of diabetic rats. Methods A total of 45 male SD rats were randomly divided into normal control group (NC, n=15) and experimental group (n=30). Diabetes was induced by tail vein injection with streptozotocin (STZ, 45 mg/kg). The well-established 28 diabetic model rats were then randomly divided into diabetes group (DM, n=14) and Jinqi Jiangtang tablet administration group (Jinqi, n=14). The rats in Jinqi group were given Jinqi Jiangtang tablet solution by gavage at a single dose of 2.1 g·kg-1·d-1 for 18 weeks, while NC group and DM group were given 0.9%NaCl in the same way. All rats were sacrificed after 18 weeks. The circulating Th17 frequencies were assessed using flow cytometry. Serum IL-17 and IL-23 levels were measured by enzyme-linked immunosorbent assay. The pathological changes in kidney were studied by electron microscope. The expressions of IL-17 and IL-23 in kidney were detected using immunohistochemistry. Results (1) Compared with the group NC, the circulating Th17 frequencies were significantly increased in group DM and group Jinqi. The circulating Th17 frequencies were significantly lower in group Jinqi than those in group DM. (2) Compared with the group NC, the serum IL-17 and IL-23 levels were significantly increased in group DM and group Jinqi. The serum IL-17 and IL-23 levels were significantly lower in group Jinqi than those in group DM. (3) In group DM, irregular thickening of glomerular basement membrane, fusion of epithelial cell foot processes and mesangial expansion were observed by electron microscope. The above-mentioned pathological changes were improved inthe group Jinqi. (4) Compared with the group NC, the expressions of IL-17 and IL-23 in the renal cortex were significantly increased in group DM and group Jinqi, and those were significantly lower in group Jinqi than those in group DM. Conclusion The activation of Th17 and the increased expressions of IL-17 and IL-23 in kidney play a potential role in diabetic nephropathy. Jinqi Jiangtang tablet can improve diabetic nephropathy through inhibiting the activating Th 17 and decreasing the expression of IL-17 and IL-23 in kidney.

Objective To evaluate the safety and diagnostic accuracy of preoperative endoscopic ultrasound-guid﹣ed fine-needle aspiration in patients with pancreatic cancer. Methods 256 patients with pancreatic cancer from Jan﹣uary 2010 to December 2014, 82 were considered resectable on the basis of cross-sectional imaging findings. Of these patients, 54 underwent EUS-FNA before surgery (FNA+group) and 28 underwent surgery without preoperative EUS-FNA (FNA- group), the diagnosis result of EUS-FNA and the survival time of the two groups were observed. Results All 54 lesions were visible on EUS, and all 54 attempts at FNA were technically successful. The diagnostic accuracy according to cytology and histology findings was 94.44 % (51/54) and 88.89% (48/54), respectively, and the total accuracy was 94.44 % (51/54). Two patients developed mild pancreatitis and two hemorrhage after EUS-FNA but were successfully treated by conservative therapy. No severe complications occurred after EUS-FNA. In the FNA+and FNA- groups, the median relapse-free survival (RFS) was 282 and 265 d, respectively (P>0.05), and the median overall survival (OS) was 568 and 557 d, respectively (P>0.05). RFS and OS were therefore not inferior in the FNA+group. These data indicate that the usage of EUS-FNA did not influence RFS or OS, nor did it increase the risk of other complications. Conclusions Preoperative EUS-FNA is a safe and accurate diagnostic method.

Objective To investigate the therapy effect of fermented cordyceps powder on diabetic cardiomyopathy, and the effect on expressions of NLRP3, Caspase-1 and interleukin (IL)-1βin myocardium of diabetic rats. Methods A total of 45 male SD rats were randomly divided into normal control group (group CON), diabetes group (group DM) and fermented cordyceps powder administration group (group CS, 1 g · kg-1 · d-1). Diabetes rat model was induced by tail vein injection with streptozotocin (45 mg/kg) in group DM and group CS. The rats in group CS were given fermented cordyceps powder solution by gavage at a single dose of 1 g·kg-1·d-1 for 18 weeks. Rats of group CON and group DM were given 0.9%NaCl in the same way. All rats were sacrificed after 18 weeks. The pathological changes in myocardium were observed by HE staining and electron microscope. The expression of NLRP3 in myocardium was detected by Western blotting. The expression levels of NLRP3, Caspase-1 and IL-1βin myocardium were detected by immunohistochemistry. Results (1) Myocardial necrosis and fibrosis and mitochondrial damages were observed under electron microscope in group DM. The above-mentioned pathological changes were improved in the group CS. (2) The result of Western blotting showed that the expression of NLRP3 in myocardium was significantly increased in group DM and group CS than that in group CON, and the expression of NLRP3 was significantly lower in group CS than that in group DM. (3) The result of immunohistochemistry showed that, compared with the group CON, the expressions of NLRP3, Caspase-1 and IL-1β in myocardium were significantly increased in group DM and group CS, and which were significantly lower in group CS than those in group DM. Conclusion Fermented cordyceps powder can improve diabetic cardiomyopathy through decreasing the expressions of NLRP3, Caspase-1 and IL-1βin myocardium.

Objective To investigate the expression levels of tumor necrosis factor alpha (TNF-α),interleukin-6(IL-6) and the change of serum ferritin in patients with intracranial aneurysm and its clinical significance.Methods 22 patients with intracranial aneurysm and 16 cases of traumatic brain injury who recevied operation in Department of Neurosurgery in Quzhou People's Hospital from Jan.2014 to Jan.2015 were enrolled as observation group and control group.The intracranial aneurysm tissues and normal cerebral vascular tissues were collected respectively to detect the situation of inflammatory cell infiltration,and the expression of TNF-α and IL-6 was detected by HE staining and immunohistochemical staining.The serum was collected on hospitalized,postoperative 3 days and postoperative 7 days to detect serum ferritin.Results The positive cells were observed in the observation group after immunohistochemical staining,in which the expression levels of TNF-α [(0.194 ± 0.074) vs.(0.135 ± 0.047),t =2.799] and IL-6 [(0.152 ± 0.057) vs.(0.103 ± 0.028),t =3.494] were significantly higher than those in the control group(P =0.008,0.001).The serum ferritin level in the observation group was significantly higher than that in the control group at postoperative 3d [(232.25 ± 105.26) ng/mL vs.(169.51 ± 66.24) ng/mL,t =2.097] and postoperative 7d[(263.39 ± 114.73) ng/mL vs.(166.57 ± 73.71) ng/mL,t =2.955] (P =0.043,0.005).The difference of serum ferritin on different day in the observation group also was statistically significant(F =8.625,P =0.003).Conclusion The expression levels of TNF-α and IL-6 in intracranial aneurysms were high,which may be one of the important factors in the formation of intracranial aneurysms,and it provides an important reference of early prevention and drug treatment for patients with intracranial aneurysm.The serum ferritin is related to the rupture and hemorrhage of intracranial aneurysm,which can be used to judge prognosis and guide rational treatment,and worth further study to confirm.

Objective To study the effect of blood glucose fluctuations on the prognosis of thrombolytic therapy in patients with acute cerebral infarction. Methods A total of 83 consecutive patients with acute cerebral infarction admitted to the Department of Neurology,General Hospital of Beijing Military Command ( the Affiliated 81st Brain Hospital ) from January to November 2013 were enrolled retrospectively. They were divided into cerebral infarction with type 2 diabetes mellitus group (DMCI group,n=47) and cerebral infarction without type 2 diabetes mellitus group (NDMCI group,n=36) according to whether they had diabetes mellitus or not and the results of oral glucose tolerance test at day 7 after admission. Continuous glucose monitoring system ( CGMS) was used to monitor glucose for 72 hours at day 7 after admission. The mean blood glucose, standard deviation of blood glucose level, mean blood glucose fluctuation,and hemorrhagic transformation during the follow-up period,as well as vascular recanalization were observed and compared. At day 90,the modified Rankin scale (mRS) score was used to evaluate the prognosis of the patients. Results ( 1 ) Comparing the dynamic glucose parameters of the patients with acute cerebral infarction in both groups,the mean blood glucose,standard deviation of blood glucose level,mean blood glucose fluctuations at 24 hours in patients of the DMCI group were higher than those of the NDMCI group ( 8 . 3 ± 2 . 6 mmol/L vs. 5 . 8 ± 1 . 3 mmol/L,2. 1 ± 0. 4 mmol/L vs. 1. 6 ± 0. 6 mmol/L,4. 3 ± 0. 8 mmol/L vs. 3. 6 ± 0. 5 mmol/L). There were significant differences (t=31. 419, 15.537,and 15. 372,respectively;all P<0. 01). (2) Four patients (8.5%) in the DMCI group had hemorrhagic transformation during the follow-up period,17 cases (36. 2%) had good recanalization,and 15 cases (31.9%) had good prognosis (the mRS score < 2 at day 90);1 patient (2.8%) in the NDMCI group had hemorrhagic transformation,21 patients (58. 3%) had good recanalization,and 21 cases (58. 3%) had good prognosis. There was significant difference between the recanalization after thrombolysis and the prognosis in patients of both groups (P<0. 05). Conclusion The great fluctuations of blood glucose in acute cerebral infarction patients with type 2 diabetes mellitus may be an important factor of affecting its prognosis of thrombolytic therapy.
