Objective In the heart,autophagy is important for the turnover of organelles at low basal levels under normal conditions,but is upregulated in response to stresses such as ischemia/reperfusion and in cardiovascular diseases such as heart failure. It can prevent the heart from injury under stress conditions. This study was designed to test the hypothesis that autophagy would be upregulated in the myocardium of children with cyanotic congenital cardiac defects. Methods Eighteen children with cyanotic (n=10) or acyanotic cardiac defects (n=8) who were admitted in our hospital from October 2008 to April 2009 and received surgical treatment were investigated. Samples from the right ventricular myocardium taken immediately after aortic clamping were morphologically studied with transmission electron microscopy for the ultrastructure. Microtubule-associated protein 1 light chain 3 (LC-3) was detected by Western blot analysis in the obtained samples. Results Children with cyanotic cardiac defects had higher oxyhemoglobin saturation before operation than those with acyanotic cardiac defects. Electron microscopy showed that the former group had more mitochondria,disordered arrangement,swollen endoplasmic reticulum and typical autophagosomes in the myocardial cytosol. LC3-II were significantly elevated in patients with cyanotic compared with those with acyanotic congenital cardiac defects (P

Objective [WT5”BZ] To evaluate the surgical treatment of insulinomas in the head and neck of the pancreas. [WT5”HZ]Methods [WT5”BZ] Data of 43 patients with insulinomas located in the head and neck of the pancreas during the past 16 years in PUMC Hospital were analyzed retrospectively.[WT5”HZ] Results [WT5”BZ] The average age of patients was 37 years old with an average preoperative history of 2 7 years. The preoperative accuracy of PTPC, DSA, B ultrasound, CT and MRI were 89 5%,72 5%,22 4%,25 3% and 66 7% respectively. The accuracy of intraoperative palpation was 97 8%. Enucleation of tumors was usually applied, and distal pancreatectomy or Roux en Y pancreaticojejunostomy were performed in 7 cases. The incidence of postoperative pancreatic leakage was 32 6%.[WT5”HZ] Conclusions [WT5”BZ] Selection of operation methods depends on the relationship of tumor with pancreatic duct and bile duct. Intraoperative monitoring of blood glucose is an essential mean to verify the complete resection of tumors. [WT5”HZ]

Objective To investigate the pathogenesis of diagnosis and treatment for delayed gastric emptying(DGE) after pancreaticoduodenectomy(PD).Methods The clinical data of 226 patients admitted between 1983 and 2001 undergoing PD were retrospectively analysed.Results In 226 PD cases DGE was observed in 62 patients(27.4%). Patients with DGE had longer duration of nasogastric tube drainage(21 days vs. 5.6 days).All patients were treated by non-operative methods. The average recovery time was 21 days.Conclusions It is emphasized that DGE has been associated with several factors, including preoperative status of diabetes, bowel obstruction, and jaundice,and postoperative pancreatic fistula, intra-abdominal abscess. Octreotide administration had no relation with the occurrence of DGE.

OBJECTIVETo observe the prevention and clinical efficacy of combination of Liuwei Dihuang Pill (LDP) and Ginkgo Leaf Tablet (GLT) for early diabetic retinopathy (DR).

METHODSUsing randomized, double-blind, double simulation, parallel controlled clinical trial, 140 type 2 diabetes mellitus (T2DM) outpatients were recruited and assigned to the treatment group and the control group, 70 in each group. All patients received basic Western medicine treatment (such as blood glucose and pressure control). Patients in the treatment group took LDP (8 pills each time, 3 times per day) and GLT (19.2 mg each time, 3 times per day), while those in the control group took LDP placebos and GLT placebos. All treatment lasted for 24 consecutive months. All subjects were followed-up every month. The general clinical data as sex, age, and metabolic data such as blood glucose, blood pressure, blood lipid, and DR prevalence rate were collected and statistically analyzed.

RESULTSThere was no significant difference in levels of blood glucose, blood pressure, or blood lipid between the two groups (P > 0.05). After treatment the DR incidence rate was significantly lower in the treatment group than in the control group [3.1% (2/64) vs 18.6% (11/59), P < 0.05)]. Meanwhile, the DR prevalence rate of the treatment group was also significantly lower than that of the control group [6.3% (4/64) vs 20.0% (13/59), P < 0.05].

CONCLUSIONCombination of LDP and GLT could effectively prevent and treat the development of DR in T2DM patients.

ObjectiveTo investigate the correlation between the level of resistin and the insulin resistance(IR) and the incorporation of microamount albuminuria(MA) of type 2 diabetes mellitus (T2DM).MethodsTwo hundred and twenty T2DM patients and 40 normal subjects (control group) were enrolled in this study.Two hundred and twenty T2DM patients were divided into 4 groups,IR group (group A,79 cases),non-IR group (group B,48 cases),IR complicating MA group (group C,51 cases),non-IR complicating MA group(group D,42 cases).The fasting serum resistin was measured by enzyme-linked immunosorbant assay (ELISA),and the fasting plasma glucose (FPG),glycosylated hemoglobin (HbA1c),fasting insulin (FINS) was also determined.ResultsThe level of fasting serum resistin in group A,B,C and D was higher than that in control group [(33.45 ± 1.37),(23.36 ± 1.47),(44.45 ± 1.39),(37.45 ±1.57) μ g/L vs.( 17.44 ± 1.26 ) μ g/L],and there was significant difference among 5 groups (P ＜ 0.01 ).The level of fasting serum resistin in group A was higher than that in group B (P ＜ 0.01 ),and the level of fasting serum resistin in group C was higher than that in group D (P ＜ 0.01 ).The level of fasting serum resistin was both higher in group C and D than that in goup A and B (P＜ 0.01 ).Correlation analysis showed the fasting serum resistin was positively correlated with body mass index(BMI),FPG,HbA1c and FINS in group A(r =0.35,0.46,0.37,0.49,P ＜0.05),and the fasting serum resistin was positively correlated with HbA1c,BMI,systolic blood pressure and diastolic blood pressure in group C(r =0.45,0.32,0.37,0.29,P ＜ 0.05 ).ConclusionsSerum resistin may participate in the process of IR and the formation of MA.It may become one of the diagnostic standard of the IR and one of the important index to estimate the MA.

Objective To investigate the expression level of miRNA-146a (miR-146a) in retinal pigment epithelial (RPE) cells aging and age-related macular degeneration (AMD),and discuss its regulation mechanism of AMD by repressing VEGF-A.Methods The expressions of miR-146 and VEGF-A were examined by qRT-PCR in RPE cells in mice aged 2 months,8 months,12 months,18 months or 24 months,and in RPE cells from 75 years old AMD patients.The protein level of VEGF-A was also detected by Western Blotting.Finally,the effects of overexpression of miR-146a in APRE-19 cell line on expression of VEGF-A was checked.Results MiR-146 was up-regulated to 8 times or 24 times at 18 months or 24 months aged mice,and the expression of VEGFA was down-regulated in aging RPE from 1.5 times to 0.8 times.However,the expression of miR-146 decreased to 14.5 times and VEGF-A increased in RPE cells of AMD.In cultured cells,overexpression of miR-146a inhibited the expression of VEGF-A.Conclusion Up-regulation of miR-146a in aging RPE cells and its down-regulation in AMD suggest a potential of miR-146a as molecular marker.MiR-146a overexpression inhibits the expression of VEGF-A,supporting a potential clinical treatment of miR-146 in AMD.

Objective To investigate the effect of vascular tortuosity and bending radius on the new type knitting stents (LVIS stent ) releasing on the cavernous sinus segment of internal carotid artery. Methods From December 2015 to January 2016,31 consecutive patients with wide-neckedaneurysm treated with LVIS stents and the proximal end of the stent released in the cavernous segment at the Department of Neurosurgery,Changhai Hospital,the Second Military Medical University were enrolled. According to whether the stents completely adhered to the walls or not after the first release,they were divided into two groups:a satisfactorily release group (n =23 )or an unsatisfactorily release group (n =8 ). The differences of vascular tortuosity and bending radius of the 2 groups were compared.Results Thevascular tortuosities of the satisfactorily release group and the unsatisfactorily release group were 118° ± 23° and 147° ± 19° respectively. There was significant difference (P=0. 028). The vascular bending radii were 3. 4 ± 0. 7 mm and 2. 8 ± 0. 7 mm respectively. There was significant difference (P=0. 042). The mean vascular tortuosity was larger and the mean vascular bending radius was smaller in the unsatisfactorily release group. Conclusions The greater the vascular tortuosity,the smaller the vascular bending radius may be connected with the unsatisfactorily release in the LVIS stent. The evaluation of vascular tortuosity is conductive to the guidance of the stent release technique before stent implantation.
