Objective To investigate the efficacies of laparoscopic Roux-en-Y gastric bypass (LRYGB) surgery in the treatment of patients with different body mass indexes (BMI) and type 2 diabetes mellitus.Methods The clinical data of 40 patients with type 2 diabetes mellitus who underwent LRYGB surgery at the Shengjing Hospital of China Medical University from January 2013 to December 2013 were retrospectively analyzed.According to different BMI,8 patients with BMI ＜ 27.5 kg/m2 were allocated into group 1,14 patients with BMI≥27.5 kg/m2 and ＜32.5 kg/m2 in group 2 and 18 patients with BMI≥32.5 kg/m2 in group 3.Forty patients were followed up via telephone interview and food habits questionnaire by weight loss file managers of Shengjing Hospital and the fourth Affiliated Hospital of China Medical University.All the patients received the reexamination of blood test and data collection at postoperative year 1.The preoperative and postoperative 1-year fasting plasma glucose,glycosylated hemoglobin (HbA1 c),BMI and C-peptide were collected and detected.The fasting plasma glucose ＜ 7.00 mmol/L and HbA1 c ＜ 7.00％ were used as a standard of complete remission.Count data and comparison of rates were analyzed using the chi-square test.Measurement data with normal distribution were presented as x ± s and analyzed by the t test.Skew distribution data were described as M (range) and analyzed by the Wilcoxon rank sum test.Repeated measurement data were analyzed by the repeated measures ANOVA.Results Forty patients received successful LRYGB surgery without perioperative complications,and were followed up for 1 year at the Shengjing Hospital (23 patients),the fourth Affiliated Hospital (8 patients) and other hospitals (9 patients).Of the 40 patients,85.0％ (34/40) of patients had no postoperative long-term obvious malnutrition,anastomotic stenosis,ion disorders and digestive tract dynamic obstacles,15.0％ (6/40) of patients were not adapted to the change of life habits such as frequent nausea and vomiting.Five patients with different degrees of frequent vomiting,abdominal pain and night heartburn within postoperative 1 month had the remission of synptoms after symptomatic treatment.One patient in group 2 had a symptom of hypertonic coma due to intake of oral high-sugar drinks at postoperative 1 week and then was cured by hospitalization.The fasting plasma glucose,HbA1c and BMI in group 1 from preoperation to postoperation were decreased from 11.07 mmol/L (range,6.00-17.00 mmol/L) to 7.18 mmol/L (range,6.00-15.00 mmol/L),from 8.85％ (range,6.00％-11.00％) to 6.35％ (range,6.00％-9.00％) and from 26.0 kg/m2 (range,22.0-27.0 kg/m2) to 22.2 kg/m2 (range,20.0-25.0 kg/m2),with significant differences (F =2.413,3.256,6.750,P ＜ 0.05).C-peptide from preoperation to postoperation was decreased from 1.20 nmol/L (range,1.00-3.00 nmol/L) to 1.07 nmol/L (range,1.00-2.00 nmol/L),with no significant difference (F =1.678,P ＞ 0.05).The remission rate of diabetes in group 1 was 3/8.The fasting plasma glucose and HbA1c in group 2 from preoperation to postoperation were decreased respectively from 10.73 mmol/L (range,7.00-19.00 mmol/L) to 5.89 mmol/L (range,5.00-9.00 mmol/L) and from 8.00％ (range,6.00％-15.00％) to 5.85％ (range,5.00％-8.00％).The BMI from preoperation to postoperation was decreased from 31.0 kg/m2 (range,29.0-32.0 kg/m2) to 25.5 kg/m2 (range,21.0-29.0 kg/m2),with significant differences in the above 3 indexes (F =5.449,4.008,-3.296,P ＜ 0.05).C-peptide from preoperation to postoperation was decreased from 1.53 nmol/L (range,1.00-5.00 nmol/L) to 1.52 nmol/L (range,1.00-6.00 nmol/L),with no significant difference (F =-0.251,P ＞ 0.05).The remission rate of diabetes in group 2 was 10/14.The fasting plasma glucose,HbA1c and BMI in group 3 from preoperation to postoperation were decreased from 9.44 mmol/L (range,5.00-16.00 mmol/L) to 6.65 mmol/L (range,4.00-15.00 mmol/L),from 7.90％ (range,6.00％-11.00％) to 6.45％ (range,5.00％-9.00％) and from 36.9 kg/m2 (range,33.0-47.0 kg/m2) to 27.7 kg/m2 (range,23.0-34.0 kg/m2),with significant differences (F =-3.027,-3.410,-3.724,P ＜ 0.05).C-peptide from preoperation to postoperation was decreased from 2.91 nmol/L (range,0.00-9.00 nmol/L) to 2.13 nmol/L (range,0.00-6.00 nmol/L),with no significant difference (F =-3.724,P ＞ 0.05).The remission rate of diabetes in group 3 was 14/18.There was no significant difference in the remission rate of diabetes of 3 groups (x2 =4.460,P ＞ 0.05).There were significant differences in the changing trends of fasting plasma glucose and BMI among the 3 groups (F =3.200,22.500,P ＜ 0.05).There were no significant differences in the changing trends of HbA1c and C-peptide among the 3 groups (F =0.720,1.640,P ＞ 0.05).Conclusion LRYGB surgery is feasible for the treatment of type 2 diabetes mellitus with effectively decreasing fasting glucose,and should be performed on patients with BMI ≥ 27.5 kg/m2 instead of patients with BMI ＜ 27.5 kg/m2 according to a correlation of blood glucose control and preoperative BMI.

OBJECTIVETo summarize the clinical manifestation and diagnosis of ganglioneuroma in spine and investigate the clinical effect of surgical treatment.

METHODSThe clinical data of 6 patients underwent a surgery for ganglioneuroma in spine from January 2008 to January 2015 were retrospectively analyzed. There were 4 males and 2 females, aged from 2 to 63 years old with an average of 34.6 years. The courses of disease were from 3 days to 17 years. Five patients complicated with superficial hypesthesia in correlative level of tumor, and the muscle strength under tumor plane had decreased at different levels, with the strength of grade II-IV. Two cases complicated with hypermyotonia and positive bilateral Hoffmann's and Babinski sign. Five cases were sporadic lesion in correlative spinal canal and one case complicated with the giant occupying lesion in thoracic cavity.

RESULTSSix operations had been performed including 5 en bloc and 1 subtotal resection. Postoperative pathological results showed tumor cells scattered or fasciculated inserted into Schwann cells in the stroma. In 2 patients complicated with radiculalgia before operation, 1 case was relieved and 1 was invariant after operation. All 4 patients with preoperative dyscinesia in the limbs obtained improvement after operation. All the patients were followed up from 0.3 to 6.8 years with an average of 2.5 years. At the final follow-up, according to ASIA grade, 5 cases were good and 1 case was invariant. During the follow-up, only 1 patient experienced chemoradiation because of merging ganglioneuroblastoma and receiving subtotal resection. No recurrence in other 5 cases.

CONCLUSIONGanglioneuroma is a benign and rare tumors in spine. Clinically, radicular pain and sensory-motor disorders are the main manifestations. Its diagnosis depends on pathological examination. Prognosis of surgical treatment is good.

Objective To explore the effects of comprehensive rehabilitation on elbow joint dysfunction in preschool children with humeral supracondylar fracture. Methods 16 cases of humeral supracondylar fracture with elbow joint dysfunction were treated with fumigation of Chinese medicine combined with manipulation and physical therapy. The range of motion (ROM) and Hospital for Special Surgery Scoring System (HSS2) were used to evaluate the effects of treatment. Results ROM of elbow joint improved significantly after treatment (P<0.001), and all the children reached "excellence" after treatment according to HSS2. Conclusion Comprehensive rehabilitation is effective on elbow joint dysfunction in preschool children with humeral supracondylar fracture.

Medical biochemistry is a very important basic curricular in medicine teaching.But its theory is abstract,so it is difficult for teachers to teach.On the other hand,the students feel it hard to learn too,because they don't know how these theories are applied.We have applied case-based teaching in medical biochemistry teaching.These methods effectively improve students' enthusiasm to study and to train their scientific thinking in preliminary.Following this way we have explored a new way to elevate teaching qualities and search new teaching model and to further reform present medical biochemistry teaching model.

Objective To investigate the prevalence of adult epileptic patients with interictal depression symptoms(IDs) and identify early predictors of IDs. Methods Adult patients with epilepsy were recruited ( n =110,45 females and 65 males) ,age between 16 and 67 years ( median 24 years). The sociodemographic and clinical factors of patients were recorded. Hamilton Depression Scale ( HAMD ) were applied to evaluate interictal symptoms of depression ( at least 72 hours after the last epileptic seizure). According to HAMD score,the epileptic patients were divided into IDs ( ≥8 ) and non-IDs(＜8) groups. The sociodemographic and clinical factors were compared between the two groups to identify the prevalence and early predictors of IDs in adult epileptic patients.Results The prevalence of IDs in adult patients with epilepsy was 38.2% ,49.0% in active epilepsy and 12.1 %in seizure freedom. 30.0% ,5.5% ,and 2.7% were experiencing mild-to-moderate (HAMD score≥8),moderateto-severe ( ≥ 18 ) and severe ( ≥25 ) depression. 42 patients who met the HAMD score≥8 were classified as IDs group,and the remaining 68 patients were classified as non-IDs group. With multiple stepwise backward logistic regreasion, independent predictors of IDs were epileptic seizures ( OR = 8. 845, P = 0. 003 ); symptomatic or cryprogenic epilepsy ( OR = 3.132, P = 0. 045 ); prolonged duration of illness ( OR = 1. 106, P = 0.004 ) and employment status (OR =0. 154, P=0.001 ). There were no relationship between seizure frequency and severity of IDs ( Kruskal-Wallis test, x2 = 4.5, P = 0. 104). Conclusion IDs is a frequent psychiatric comorbidity in adult patients with epilepsy. The prevalence of IDs is higher in those with active epilepsy compared with those in seizure freedom and most of them are mild-to-moderate. Epileptic seizure, symptomatic or cryprogenic epilepsy, prolonged duration of illness and employment status are independent predictors of IDs, but seizure frequency has nothing to do with the IDs severity of patients.

Objective To assess the neuropsychological characteristics in active epileptic patients and investigate itsrisk factors. Methods Ninety adult epileptic patients included 60 active epileptic patients (two or more unprovoked seizures within 12 months) and 30 age-, sex-, education-, course of disease- and seizure type-matched seizure-free subjects (without epileptic seizure for at least 1 year) . The neuropsychological tests including trail making test,digit symbol test, verbal fluency test,digit span test and hamilton depression scale( HAMD) ,were used to detect mental and motor speed, attention, language, working memory and depression symptoms respectively. The neuropsychological tests were compared between active and seizure-free epileptic patients and identified the risk factors of neuropsychological deficits in active epileptic patients. Results Compared to seizure-free subjects, active epileptic patients had significantly worse scores in digit symbol test, verbal fluency test, digit span test ((47.45 ±18. 812) vs(56.40 ±13. 631), (25. 25 ±8. 163) vs(30.40 ±8. 414), (10. 39 ±2. 228) vs( 11. 80 ± 2.074) respectively) ; more time to accomplish the trail making test A and B((64. 35 ±31.710) vs( 45. 47 ± 16. 309) , ( 133. 18 ± 47. 331 ) vs ( 98. 00 ± 35. 003 ) respectively) ; and higher scores in depressive symptoms ((9.12 ±6.219)vs(3.77 ±3.997) ,all P<0.05). Within active epileptic group,significant predictors of neuropsychological deficits were identified in a stepwise linear regression analysis: advancing age was significantly negatively correlated with digit symbol test(β = -0. 468, P = 0. 000) , digit span test (β = -0. 439, P = 0. 000), trail making test A (β =0.365, P = 0.003) and B(β = 0.346, P=0.002) ; higher scores on depressive symptoms was significantly negatively correlated with digit symbol test (β = -0.244, P = 0.015) ; mental work,high-education level and monotherapy were positively correlated with some of the cognitive function subscales. Conclusion This study suggests that active epilepsy can have a direct adverse effect on cognition and depression symptoms. Multi-drug therapy, severity of depression symptoms, advancing age, low-education level and non-mental work are the predictors of neuropsychological impairment in active epilepsy. In addition, good seizure control even after 1 year can have a beneficial impact on cognitive and depression prognosis.

Objective: To evaluate the feasibility ofin vitro balloon dilatation for treating aortic coarctation infants younger than 6 months. Methods: A total of 13 aortic coarctation infants treated in our hospital from 2011-01 to 2015-12 were summarized. The patients were at the mean age of 3.4 months (from 20 days to 6 months), with the mean body weight of 4.8 kg (from 3.6 kg to 6.2 kg) including 9 male. Aortic coarctation segments were resected during the operation and the resected segments were expanded by percutaneous transluminal angioplasty (PTA) via (2-4) times diameter balloon dilatation. The diameters of resected aortic segments were recorded before and after expansion; the change of vascular middle smooth muscle layer was observed by HE staining. Results: There were 8 cases with non-restricted ventricular septal defect (VSD) and 3 of them received staging operation, 2 with atrial septal defect (ASD), 3 with bicuspid aortic valve, 3 with patent ductus arteriosus (PDA) and 1 with pericardial effusion. The resected aortic segments presented that 9 patients had diaphragm type narrow and 4 had tube type narrow. After PTA, the diameters of resected aortic segments were slightly increased for the mean of 0.2 mm and no obvious change was observed; HE staining showed that the vascular inner mucosa was shed, while the middle smooth muscle layer was intact. Conclusion: Balloon dilatation had the poor effect for treating aortic coarctation infants younger than 6 months; surgical procedure could be applied for treating the relevant patients.

Objective To discuss one-stage surgical repair of interrupted aortic arch ( IAA) in neonates and young in-fants, summarize follow-up results and subsequent treatments.Methods From September 2010 to December 2014, a series of 38 consecutive neonates and young infants ( M/F =26/12 ) with IAA were admitted in our surgical group to receive surgical treatment, with a median age of 11 days(1 day to 5 months) and a median body weight of 4.1 kg(1.8 to 5.8 kg).IAA was type A in 24 cases, type B in 13 cases and type C in 1 case.Associated cadiovascular anomalies were common except 2 cases, including atrial septal defect(n=23), ventricular septal defect(n=36), left ventricular outlet tract obstruction(LVOTO)(n=7), anomalous left pulmonary artery from aorta(n=1), truncus arteriosus(n=1).There were 5 cases of airway stenosis in 28 cases of CT angiography and 3D airway reconstruction.All the 38 cases were admitted with differential cyanosis.36 cases were recieved one-stage surgical repair except 2 cases died before operation.35 cases of IAA associated with intracardiac anom-alies were repaired through a median sernotomy.Cardiopulmonary bypass(CPB) was performed with two canulations in ascend-ing aorta and main pulmonary artery.Selective cerebral perfusion(n=21) or circulatory arrest(n =14) was carried out with body temperature of 18℃-23℃.After the patent ductus arteriosus tissue was completely resected , a continuous end-to-end or end-to-side suturing with 7/0(8/0) prolene was performed.In 1 type B cases with expected excessive anastomotic tension, the left subclavian artery was cut off to release the aortic arch .The associated anomalies were repaired during the cooling or re-warming period.Chest close was delayed to carry out no more than 24-72 h postoperatively in 16 cases.The other one type A IAA case without intracardiac anomaly was repaired through a standard left posterior lateral incision .Patients were strictly fol-lowed up with a standard protocol.Complications such as aortic arch restenosis, new LVOTO, new airway stenosis, and so on, were specialy focused on during the follow-up period.If needed, reoperation or transcatheter intervention was applied to treat the complications.Results Two cases died before operation and another 2 died in the early period postoperatively because of pulmonary hypertension crisis and severe tracheal stenosis, respectively.Sudden death was in 1 case during the follow-up peri-od.Median CPB time was 138 min(105-208 min) and median selective cerebral perfusion or circulatory arrest time was 24 min(16-35 min) .Mechanical ventilation time was 2-25 days.Blood pressure difference between the upper and lower limbs was less than 20 mmHg in all the patients before discharge.29 cases(85.29%) was followed up for 28 months(9 -60 months).3 cases were received reoperation in 5 cases of newly detected LVOTO.One case received reoperation in the 7 preop-erative LVOTO cases because of newly detected LVOTO(blood pressure gradient more than 40 mmHg).Two cases with aortic arch restenosis received percutaneous transcatheter ballon dilation .One case with new left main bronchus stenosis after opera-tion was strictly followed up.Conclusion IAA is a rare and severe congenital heart disease.Positive surgical repair should be performed after definite diagnosis being made .Although satisfactory results can be obtained with one-stage primary operation , IAA is a kind of progressive chronic disease.New postoperative LVOTO should be focused on becasue it will need reoperation or even the third operation .

Objective To detect COX-2 expressions in primary tumor and axillary lymph node tissues of breast cancer,and to study the relationship between COX-2 expression in breast cancer and lymph node metastasis.Methods The expressions of COX-2 in 9 normal breast tissues,50 primary breast cancer tissues,19 positive axillary lymph nodes and 31 negative axillary lymph nodes were detected with immunohistochemistry S-P method.Results COX-2 staining was granular and localized to the cytoplasm of tumor cells.In normal breast tissues,COX-2 staining was granular and localized to mesenchymocyte.In negative lymph nodes,COX-2 staining was granular and localized to macrophagus cytoplasm.The positive expression rates of COX-2 in normal breast tissues,primary breast cancer tissues,positive axillary lymph nodes and negative axillary lymph nodes were 11.1%,60.0%,84.2%,and 32.3%,respectively.There were significant differences of COX-2 positive expression rates between normal breast tissues,primary breast cancer tissues and positive axillary lymph nodes(P
