Objective To investigate the risk factor for new-onset diabetes after transplantation (NODAT) and the relationship between NODAT and arterial stiffness. Methods Oral glucose tolerance test (OGTT) was performed on 195 patients with renal transplantation. The degree of arterial stiffness, which was determined by brachial ankle pulse wave velocity (baPWV), anklebrachial blood pressure index (ABPI) and intima-media thickness (IMT) of the carotid artery, was evaluated. Results Twenty-nine patients diagnosed as NODAT had significantly higher fasting plasma glucose before transplantation, blood pressure and incidence of hepatitis C virus (HCV) infection than in patients without NODAT. Multivariate regression analysis revealed that the risk factor of NODAT was fasting plasma glucose pre-transplantation, HCV infection and systolic blood pressure.The independent determinant of the advanced arterial stiffness on NODAT was the statement of hypertension and age. Conclusions High fasting plasma glucose prior to transplantation, HCV infection and high blood pressure are risk factors for NODAT in patients after renal transplantation.Strict control of blood pressure is the key way to prevent the NODAT and atherosclerosis.

Objective To compare the license issuance and status of administration of laboratory animals in Jiangsu and Zhejiang provinces in the last five years, and to study the status of laboratory animal license management and industry development level in the two provinces.Methods Taking a combination of current status investigation, literature search, information collection and comparative analysis, to study the similarities and differences in the annual issuance of laboratory animal licenses, level of environmental facility, type of institution division, regional distribution of institutions, etc.in the two provinces over the last five years.Results Over the past five years, the total number of the issued laboratory animal licenses and approved institutions in Jiangsu province are significantly more than in Zhejiang province.The proportion of barrier environmental facilities in Jiangsu is slightly higher than that in Zhejiang.Laboratory animal institutions cover most areas of the provinces, relatively concentrated in the capital cities and economically developed cities.The business type institutions account for the highest percentage in the two provinces.Animal species in the two provinces are approximately the same.Conclusions The industrial structure of the laboratory animals in Jiangsu province is more perfect than that in Zhejiang province.Industrialization and socialization get a higher degree in Jiangsu province.The range of regular species of the laboratory animals needs to be further expanded.The competent departments need further optimize and promote license management system of the laboratory animals.

Objective To investigate the preventive effect of the artificial nerve canal on irritating neuralgia after neurilemmoma resection.Methods Thirty patients diagnosed as neurilemmoma were divided into artificial nerve group and control group at randomly.There were 15 patients in each group.The nerves in artificial nerve group were enclosed using the artificial nerve besides neurilemmoma resection.The nerves in control group only had neurilemmoma resection.All patients were assessed with VAS for the degree of irritating neuralgia at 3 time points after operation.Calculate the incidence of irritating neuralgia and analyze the data using statistical methods.Results In control group,the VAS scores were 7.5,5.1,2.8,and the incidences of irritating neuralgia were 80％,67％,40％,respectively.In artificial nerve group,the VAS scores were 3.2,1.5,0,and the incidences of irritating neuralgia were 33％,13％,0.The VAS scores and the incidences of irritating neuralgia of two groups had significant difference by statistical analysis (P ＜ 0.05).Conclusion The artificial nerve canal can relieve the degree and decrease the incidence of irritating neuralgia after neurilemmoma resection,which is a useful method to prevent irritating neuralgia in clinic.

Background Aheration of eyeball wall caused by ocular axial extension is associated with multiple complications of high myopia.However,the study on quantitative analysis of choroidal thickness and axial length in adult high myopic patients is less.Objective This study was to investigate the choroidal thickness in high myopic eyes of adult patients and estimate the correlation of choroidal thickness with axial length,age,and spherical equivalent(SE).Methods A prospective cohort study was designed.Seventy-five eyes of 75 adult patients with high myopia were entrolled from December 2012 to May 2013,and 70 eyes of 70 age-and gendermatched healthy volunteers were included in Renmin Hospital of Wuhan University.Enhanced depth imaging (EDI)on Cirrus spectral-domain optical coherence tomography (SD-OCT) was used to measure the choroidal thickness from the outer border of the retinal pigment epithelium through the inner scleral boarder among the 11 meridians in a 500 μm intervals and range of 2 500 μm for each from fovea toward temporal and nasal lateral.The differences of choroidal thickness and axial length were compared between the high myopia group and normal control group,and the correlation of choroidal thickness with axial length,age,SE were analyzed.Results The subfoveal and mean choroidal thickness values were (146±52) μm and (142±63) μm in the high myopia group,and those in the normal control group were (306±60) μm and (271 ±71) μm,with significant differences between the two groups (t =-17.130,P=0.000; t=-15.890,P=0.000).Choroid was thickest in the temporal and then was subfovea and nasal in the high myopia group,but in the normal control group,it was subfovea,temporal and nasal in turn,and the choroidal thicknesses in various areas were thinner in the high myopia group than those in the normal control group.A negative correlation was found between the choroidal thickness and axial length in high myopia group(r =-0.580,P =0.000),and the regression equation determined a decrease of 17.943 μm per millimeter of axial length.Conclusions SD-OCT determines that choroidal thickness is decreased in highly myopic eyes compared with normal eyes.Choroidal thickness varies with the change of axial length in adult high myopia patient.These findings indicate that abnormalities of the choroids may play a role in the pathogenesis of complication of high myopia.

Objective To study the early clinical outcome of patients undergone minimally invasive direct coronary bypass(MIDCAB) surgery,and the mid-term patency of left internal mammary artery(LIMA)-left anterior descending(LAD) anastomosis.Methods From Jannuary 2007 to May 2014,47 cases underwent MIDCAB surgery in our department,with 35 males and 12 females,aged 48-76 years,with the average of (62.9 ± 8.1) years old.Types of LAD lesions were as followed:1 case was ostial total obstruction,28 severe stenosis at proximal segment,10 long and severe stenosis,3 calcified lesion with severe stenosis,5 myocardial bridge.All patients had symptomatic angina,typical myocardial ischemia could be detected by electrocardiogram for all patients with myocardial bridge.Comorbidities included:hypertension 38 cases,27 diabetes mellitus,3 COPD and 3 chronic kidney disease.Results All surgery went well without transfer to mid-sternotomy.LIMA harvest time was 38-53 minutes,mean LIMA flow rate was(22 ± 6) ml/min after anastomosis.Surgery duration was 117-143 minutes,blood loss was less than 100 ml for each operation.No blood transfusion was required.Tracheal intubation time was 4-16 hours,ICU stay time was 22-45 hours,hospital stay time was 6-10 days.There was no peri-operative death,either no myocardial infarction or cerebral vessel accident.During follow-up,all LIMA-LAD appeared to be patent by coronary CT angiography.Conclusion High patency rate of LIMA-LAD anastomosis could also be obtained during MIDCAB surgery.It was reserved as a safe and effective surgery for well-selected patients.

Objective To explore the effect of MICA-Ab expression on the prognosis of sensitized renal transplantation recipients.Methods A total of 51 sensitized recipients (PRA more than 20%) in our hospital from August 2007 to April 2010 were enrolled in the study.In these patients,29 cases received protein A immunoadsorption and detection of MICA-Ab was performed before and after protein A immunoadsorption.Other 22 patients received MICA-Ab detection when they were hospitalized.Associations of PRA,HLA-matches,acute rejection,and serum creatinine of postoperative week 1 and week 4 with MICA-Ab were analyzed retrospectively.Results Sixteen recipients (31.4%) had positive MICA-Ab expression but their acute rejection rate was not higher as compared to the patients with negative MICA-Ab expression.Recipients with PRA＞40% showed higher expression level of MICA-Ab than recipients with PRA≤40% (P≤0.05).HLA-match did not show influence on MICA-Ab expression.MICA-Ab positive group had no higher serum creatinine level than negative group in postoperative week 4.MICA-Ab level decreased significantly after protein A immunoadsorption.Conclusions MICA-Ab expression increases in the sensitive recipients but does not influence the prognosis.Protein Aimmunoadsorption can eliminate MICA-Ab effectively in sensitized recipients.

Objective To explore the expression of anti-MICA antibodies and evaluate its influence on acute rejection and renal function in early period after renal transplantation. Methods A total of 29 sensitized subjects (PRA＞20 %) were enrolled in this study. All the patients underwent protein A immunoabsorption treatment and the expression of anti-MICA antibodies was detected before and after treatment. Triple immunosuppressive regimen consisting of tacrolimus, mycophenolate mofetil (MMF) and steroid was given to prevent graft rejection. The correlation between the expression of anti-MICA antibodies and acute rejection or serum creatinine (SCr) level was analyzed.Results The expression of anti-MICA antibodies was detected in 8 candidates (27. 6 % ,8/29) ,and 6 kinds of anti-MICA antibodies simultaneously expressed were found in one individual, 3 kinds in one case,and sole kind in 6 patients. There was no significant difference in acute rejection rate between positive anti-MICA antibodies group and negative group [37.5 % (3/8) vs 38. 1% (8/21), P＞0.05). The positive expression rate of anti-MICA antibodies in the recipients with PRA ≥40% was higher than that in those with PRA ＜40% [43. 8 % (7/16) vs 7. 7 % (1/13),P＜0.05]. The SCr level in patients positive for anti-MICA antibodies was markedly higher than that in those negative anti-MICA antibodies at the 1st week postoperatively ( 135.4 ± 21.4 vs 108. 6 -+ 31.6 μmol/L, P＜0.05). The SCr level in the patients with positive anti-MICA antibodies, however, was reduced to the normal range at the 2nd week after surgery (P＞0.05). The levels of anti-MICA antibodies were continuously decreased in the candidates undergoing protein A irnmunoadsorption treatment. Conclusion Higher expression of anti-MICA antibodies exists in sensitized recipients and possesses an influence on the recovery of renal function in early postoperative period. Protein A immunoadsorption can eliminate anti-MICA antibodies effectively in sensitized recipients.

Objective To investigate the effect and mechanism of oetreotide (OCT) on DENA related hepatoeareinogenesis in rats. Methods Fresh diethylnitrosamine (DENA) solution was given to induce the model of rat hepatoeellular carcinoma. The rats were divided randomly into two groups: OCT treatment group and control group. The survival rate and hepatoeareinogenesis rate were observed. SSTR2 mRNA and protein expression were measured. Results The survival rote of OCT treatment group (70.0%, 7/10) was significantly higher than that of control group (30.0%, 6/20) (X2 = 4.344, P<0.05). 16 weeks after DENA treatment, the difference of bepatoearcinogenesis rate between the two groups was not remarkable though the value of OCT treatment group (0%, 0/10) was lower than that of control groups (30.0%, 6/20)(X2 = 3.750, P＞0.05). However, 22 weeks after DENA treatment, hepatoeareinogenesis in control group (83.3%, 10/12) was markedly higher than that in OCT treatment group (22.2% , 2/9)(X2 =7.843, P<0.01). With liver cirrhosis progressing, the expressions of SSTR2 mRNA and protein increased, and reached the peak 16 weeks after DENA treatment, then began to decrease. The expressions of SSTR2 mRNA and protein in hepatocellular carcinoma were significantly lower than those in the liver 22 weeks after DENA treatment (F = 35.010 and 13. 386, P<0.01). The expression levels in OCT treatment group were similar to those in control group 8 and 16 weeks after DENA treatment. But the expression levels in OCT group 22 weeks after DENA treatment didn't lower markedly, and were higher significantly than those in control group (t = 2.806 and 4.498, P<0.05). Conclusion OCT can inhibit efficiently hepatocareinogenesis and reduce the mortality of rots treated with DENA possibly by a mechanism maintaining the expression levels of SSTR2.

Objective To study the difference in post-resuscitation lung injury between cardiac arrest induced by anoxia and ventricular fibrillation in porcine model.Methods WuZhiShan inbred miniature pigs were randomly (random number) divided into the asphyxia (AS,n =24) and ventricular fibrillation group (VF,n =24).Cardiac arrest (CA) was induced by endotracheal tube clamping or programmed electric stimulation.Cardiopulmonary resuscitation (CPR) or defibrillation was performed for returning of spontaneous circulation (ROSC).Pulmonary perfusion/ventilation measured with isotope scanand positron emission tomography-computed tomography (PET-CT) scanning were done before and 4hrs after ROSC.The oxygenation index (OI),respiratory index (RI),oxygen delivery (DO2),blood lactic acid,and dynamic pulmonary compliance (Cdyn),airway resistance (Raw),extra-vascular lung water index (EVLWI),pulmonary vascular permeability index (PVPI),were measured before cardiac arrest,ROSC 0 h,ROSC15 min,ROSC 30 min,ROSC 1 h,ROSC 2 h,ROSC 4 h and ROSC 6 h.All pigs were sacrificed with euthanasia at ROSC 6 h and the lungs were dissected for observing histopathological changes.The level of Na +-K +-ATPase,Ca2+-ATPase,superoxide dismutase (SOD),Methane Dicarboxylic Aldehyde (MDA),Bcl-2,Bax,Caspase3 and apoptosis index (AI％) in lung were measured.Results The ROSC rate and ROSC 6hrs survival rate of in AS group was lower (P ＜0.01) than those of the VF group.The damages of lung in AS group were more severe than that in VF group by the results of enzymology and protein detection (Na +-K +-ATPase,Ca2 +-ATPase,SOD,MDA,Bax,Bcl-2 and Caspase3).AI％ was higher in AS group (P＜0.01).The deterioration of the indexes (OI,RI,DO2,Lac,Cdyn,Raw,EVLWI,PVPI) at all time points were more severe in AS group than those in VF group.Obvious filling-defect was found by the PET-CT scan of both groups,but not revealed by the isotope scan.Conclusions The lung injury after CA was closely related to the cause of CA rather than the external chest compression.Asphyxia induced more serious lung injury than ventricular fibrillation.

Spinal fractures are a big challenge to orthopedists.Thoracolumbar Injury Classification and Severity Score (TLICS),a newly developed evaluation system for thoracolumbar fractures,has proved to be valid and reliable in the last decade.However,there have still been many problems in the clinical application of TLICS in China.We discussed nine issues about the clinical application of TLICS in this article,hoping to promote better understanding and application of TLICS in Chinese spinal surgeons in their daily practice.
