Objective To investigate the value of prevention of cerebral ischemia with multi-modality neuroelectrophysiological monitoring in intracranial aneurysm embolization. Methods The clinical data of 44 patients with intracranial aneurysm treated with endovascular embolization from May 2013 to June 2014 were analyzed retrospectively. The patients were divided into two groups according to whether they used intraoperative neuroelectrophysiological monitoring. There were 21 patients in a monitoring group and 21 in a non-monitoring group. According to the site of the aneurysms,somatosensory evoked potential ( SEP),motion evoked potential( MEP),scalp electroencephalogram,and brainstem auditory evoked potential (BAEP)were monitored,and at one day after procedure,their newly developed neurological deficits and the follow up observation after 3 months in both groups were compared and analyzed. Results The intraoperative SEP,MEP,and scalp EEG changes in the monitoring group were observed in 9,3 and 4 patients,respectively. Timely preventive measures were taken for 9 of the patients with cerebral ischemia revealed by neuroelectro-physiological monitoring. At the first day after procedure,the incidence of patients with new neurological deficit was 17. 4%(4/23)in the monitoring group,and that was 47. 6%(10/21)in the non-monitoring group. There was significant difference between the 2 groups(χ2 =4. 623;P<0. 05). There was significant difference in the good prognosis rates(87. 0%[20/23]vs. 57. 1%[12/21])after 3-month follow-up (χ2 =4. 919;P<0. 05)between the 2 groups. There were no deaths in both groups. Conclusion Multimode in combination with neuroelectrophysiological monitoring may decrease ischemic complications in aneurysm interventional treatment and improve the safety of procedure.

Objective To explore the protocol of tissue matching and anti-rejection therapy in highly sensitized patients (HSP). Method The panel reactive antibody (PRA), human leukocyte antigen (HLA) matching and renal transplantation outcomes of 45 HSPs were retrospectively analyzed. Results Hyperacute rejection occurred in 2 patients. Acute rejection occurred in 9 patients and reversed by anti-rejection therapy. One year patient/graft survival rate was 95.6% / 91.1% respectively. Conclusions To avoid specific antibody through HLA matching is the key point for successful renal transplantation of HSP. Antithymocyte globulin (ATG) induction therapy combined with tacrolimus, mycophenolate mofetil therapy can decrease the rate of acute rejection and prolong graft survival.

Objective To investigate the expression of Bcl-2 associated athanogene 3 (BAG3) in cervical cancer tissues and cells and its role in epithelial mesenchymal transition (EMT) of cervical cancer.Methods (1) Cervical cancer samples were collected from September 2015 to March 2017 in the Qilu Hospital of Shandong University and Shangdong Provincial Hospital.While,50 normal tissues were collected from August 2015 to March 2017 in the Dezhou Municiple Hospital,which were obtained from patients with uterine mnyoma underwent hysterectomy and patients with cervical biopsy.Reverse transcription (RT)-PCR and western blot were used to detect the expression of BAG3 mRNA and protein,and their clinical significances were analyzed.(2) The expression of BAG3 mRNA and protein was detected using RT-PCR and western blot method in HeLa and SiHa cell lines and normal cervical epithelial cells.The experiment was divided into two groups,BAG3 small interfering RNA transfected group (st-BAG3) and the control group transfected with small interfering RNA (siRNA).Cell counting kit 8 (CCK-8) analysis was used to detect cell proliferation of two groups.Wound-healing and transwell assay were used to detect the migration and invasion ability of HeLa and SiHa cells.The xenograft model of cervical cancer in nude mice was used to observe the effect of BAG3 on tumor xenografts and the tumor-related biomarkers were tested by western blot.Results (1) The expression levels of BAG3 mRNA and protein in cervical carcinoma tissues were 1.20±0.15 and 1.10±0.16,which were significantly higher than that in normal cervical tissue,0.23± 0.04 and 0.29 ± 0.03 (both P＜0.01).The results showed that the expression levels of BAG3 mRNA and protein were significantly correlated with cervical carcinoma staging and lymph node metastasis (P＜0.05).However,its expression was not conrelated with the patient's age,pathological grade,and diameter of tumor (all P＞0.05).(2) Compared with normal cervical epithelial cells,the expression of BAG3 mRNA and protein levels in HeLa and SiHa cells were significantly increased (P＜0.01),the expression levels of BAG3 mRNA and protein in HeLa and SiHa cells transfected with si-BAG3 were significantly lower than that in control group (all P＜0.01).After post-transfected 72 hours,A value of HeLa and SiHa with transfection were significantly lower than those in control group [(0.88±0.08) vs (1.22±0.13),(0.92±0.09) vs (1.35±0.12);both P＜0.01].After post-transfected 24 hours,the migration level of HeLa and SiHa cells with transfection were significantly lower than those in the control group [(20.1±2.1)％ vs (58.6±5.6)％,and (21.1±2.1)％ vs (61.7± 5.4)％;both P＜0.01].The transmembrane cell number in HeLa and SiHa cells with transfection were 76± 11 and 71±8,which were significantly less than those in control group (131± 12 and 129± 14;both P＜0.01).After the inoculation into nude mice,tumor formation time of HeLa and SiHa cells with transfection were (9.5±0.5) and (10.5 ± 1.3) days,respectively,which were significantly longer than those in control group [(4.5±0.5) and (5.2± 1.1) days;both P＜0.05].Compared with those in the control group,the expression level of Slug,N-cadherin and matrix metalloproteinase-2 (MMP-2) protein in HeLa and SiHa cells with transfected in tumor tissues were significantly decreased (all P＜0.01),while the expression level of E-cadberin protein was significantly increased (P＜0.01).Conclusion BAG3 could be involved in the proliferation,migration and invasion of cervical cancer cells by affecting cervical cancer EMT,and BAG3 may be an effective target for the treatment of cervical cancer.

Objective To explore the feasibility and efficacy of desensitization protocol for highly sensitized renal transplant patients (HSP). Methods Thirty-five HSPs ( HLA class-Ⅰ panel reactive antibody ＞50 %), including 27 patients with a positive T and/or B cell cytotoxicity crossmatch (XM) and 8 patients with a negative T and B cell XM, received plasmapheresis plus intravenous immunoglobulin (PP-IVIG)treatment. Results The positive XM was rendered negative by PP-IVIG treatment in 25 of 27 (92.6 %)HSPs, and subsequent transplantation was performed. Two patients did not receive renal transplants due to persistent positive XM. In 25 patients receiving renal transplants, no hyperacute rejection occurred. There were 8 cases of acute rejection, including 5 cases of acute humoral rejection (AHR). All rejection episodes were reversed. During a follow-up period of 52 ± 26 months, the serum creatinine levels at 12th and 24th month were 112± 18 and 130 ± 38 mol/L respectively. The 1- and 3-year graft survival rate was 96. 0 %and 80. 0 % respectively. Conclusion The desensitization therapy by PP-IVIG is effective for HSP. High rate of AHR is the major defect of this protocol. The short-term graft survival rate after this protocol is acceptable but the long-term survival rate needs to be defined.

Objective To observe the effect of abdominal obesity on lung function in the perioperative period of complete video-assisted thoracoscopic lobectomy.Methods Collected 36 cases of peripheral lung cancer and could complete video-assisted thoracoscopic lobectomy by access conditions,18 cases in abdominal obesity group who had body mass index (BMI) ＞ 35 kg/m2 and the waist circumference ＞ 95 cm on men the waist circumference ＞ 90 cm on women,18 cases in normal weight group who had BMI ＜ 25 kg/m2 and the waist circumference ＜ 85 cm on men the waist circumference ＜ 80 cm on women.All cases had complete video-assisted thoracoscopic lobectomy and lymph node dissection with 4 holes,and recorded the operation time,before and after operation had blood gas analysis and lung function,at the same time recorded the cases of complication after operation,compared the parameters in two groups.Results The blood gas analysis had no difference before operation,but after 12 h of operation,the arterial blood oxygen partial pressure (PaO2) declined and alveolar-arterial blood oxygen partial pressure difference(PA-aO2) increased in abdominal obesity group,while the PaO2 declined and arterial blood CO2 partial pressure (PaCO2),PA-aO2 increased compared with normal weight group(P ＜ 0.05).The forced vital capacity (FVC),forced expiratory volume in 1 second(FEV1) had statistical significance in two groups before operation(P ＜ 0.05),on the third day after operation,the abdominal obesity group to himself the FVC,FEV1,maximal voluntary rentilation (MVV),functional residual capacity (FRC),carbon monoxide diffusion amount (DLCO) declined obviously except FEV1/FVC (P ＜ 0.05),compared with normal weight group,the FVC,FEV1,FRC,DLCO declined obviously (P ＜ 0.05).After operation,the lung function in abdominal obesity group,the FVC,FEV1,MVV,FRC,DLCO declined 25.8％,27.8％,20.4％,32.1％,39.1％,compared with normal weight group the FVC,FEV1,FRC,DLCO declined 31.8％,37.2％,30.2％,30.6％.The abdominal obesity group had more complication.Conclusion In the perioperative period of complete video-assisted thoracoscopic lobectomy,the abdominal obesity has more effect to lung function and must have more attentions on it,and effective weight control has important significance to operation patients.

Objective To study the relationship between neurodevelopment and early nutritional status of very low birth weight(VLBW)infants in NICU.Methods VLBW infants admitted to NICU of our hospital from January 2013 to December 2014 and received regular follow-up management at our high-risk infant outpatient clinic were retrospectively studied. All infantsˊdevelopmental quotient ( DQ) were evaluated at 3 months of corrected gestational age ( cGA) . DQ ≥130 was defined as excellent, 115-129 above medium, 85-114 medium, 70 -84 below medium and ≤69 abnormal. According to their DQ scores, infants were assigned into two groups, normal neurodevelopment group ( DQ≥85 ) and abnormal neurodevelopment group ( DQ<85 ) . Nutritional status during hospitalization between the two groups were compared.Results A total of 125 VLBW infants were recruited.At three months of cGA, 2 cases ( 1. 6℅) had excellent DQ score; 3 ( 2. 4℅) above medium; 63 ( 50. 4℅) medium;57 (45. 6℅) below medium. 68 cases (54. 4℅) in the normal development group and 57 (45. 6℅) in the abnormal group. The total energy intake, the proportion of enteral energy supply on 4 d, 7 d, 14 d after birth and amino acid supply on 4 d, 7 d were significantly higher in the normal neurodevelopment group than the abnormal group (P<0. 05). Comparing with the abnormal group, weight loss of VLBW infants in the normal neurodevelopment group was less; the time needed to reach birth weight and exclusive enteral nutrition in the normal neurodevelopment group was shorter. The differences were statistically significant between the two groups(P<0.05).Conclusions VLBW infantsˊearly nutritional status may influence their neurodevelopmental outcome.

Objective To compare the clinical effect of non-operative and operative treatment for flail chest.Methods A retrospective case control study was made on 60 cases of flail chest treated from March 2013 to April 2016.There were 42 males and 18 females,at the age range of 36-62 years [(49.8 ± 10.3)years].According to the treatment methods,the patients were divided into non-operation group (28 cases) and operation group (32 cases).Chest CT,pulmonary function and 36-item short-form health survey(SF-36) were measured in all patients 3 months and 6 months after injury.Differences in atelectasis,chest wall deformity,delayed fracture healing,pulmonary function and life quality were analyzed between the two groups.Results Compared to non-operative group at postoperative 3 months,rates of atelectasis,chest wall deformity and delayed fracture healing in operation group were obviously lower,while indices of pulmonary function pulmonary function including forced vital capacity (FVC),forced expiratory volume in one second(FEV1),one second rate (FEV1/FVC) and maximal voluntary ventilation measured value (MVV) in operation group wcre higher,and SF-36 parameters including physical functioning (PF),role-physical (RP),bodily pain (BP),general health (GH),vitality (VT),social functioning (SF) and mental health (MH) in operation group were better (all P ＜ 0.05).As to the data measured 6 months after injury,there were no significant differences between the two groups,except that the rate of chest wall deformity in non-operative group (6 cases,39％) was higher than that in operation group (11 cases,19％) (P ＜ 0.05).As to c hest CT,indices of pulmonary function and SF-36 parameters (P ＜ 0.05),there were no significant differences within operation group at postoperative 3 months and 6 months (P ＞ 0.05).Non-operation group showed better results in rate of atelectasis,rate of delayed fracture healing,indices of pulmonary function and SF-36 parameters measured 6 months after injury than the detections at postoperative 3 months (P ＜ 0.05),without difference in rate of chest wall deformity (P ＞ 0.05).Conclusions Surgical treatment of flail chest can accelerate fracture healing,reduce rate of chest wall deformity and improve life quality of patients early compared to non-operative treatment.Although there is no obvious difference in life quality of patients between operative and non-operative treatment 6 months after injury,but the chest wall deformity remains significantly different.

Objective To assess the incidence,clinic feature,pathological characteristics and prognosis of incidental prostate cancer from specimens via radical cystoprostatectomy (RCP) for muscleinvasive bladder cancer.The postoperative erectile function in patients with NVB operation are also to be evaluated.Methods Between Jan 2002 and Jan 2015,150 male patients with bladder cancer who underwent radical cystoprostatectomy in our center were included in this study.133 patients underwent open surgery and 17 cases underwent laparoscopic operation (13 patients underwent NVB operation).The average age of 150 patients was 63 years (ranging 41 to 83 years).The average tPSA was 3 ng/ml(ranging 0.2 to 7.8 ng/ml).The digital rectal examination was negative,CT results didnt exhibit the evident of abnormality in prostate.Results Overall,incidental prostate cancer was diagnosed in 11 male patients (7.3％).The pathological diagnosis are all prostatic adenocarcinoma.In those patients,the mean age was 65.5 years (ranging 42 to 82 years).The mean tPSA at the time of surgery was 2.6 ng/ml (0.3-4.0 ng/ml).There was no statistical significance of tPSA values in the incidental prostate cancer group and non risk group (2.6vs.3.2ng/ml)(P ＞ 0.05).The preoperative enhanced CT imaging showed normal prostate in 7 cases,prostate hyperplasia in 2 cases,prostate calcification in 1 cases and bladder cancer invasion into the prostate in 1 cases.9 cases of incidental prostate cancer are low risk grade (Gleason score ≤ 6,the clinical stage ≤T2).Among 11 cases,bladder cancer histologic type in 10 cases was transitional cell carcinoma and small cell carcinoma in 1 case.According to the TNM classification,4 cases were less than pT2 stage and 7 cases were more than pT3 stage.11 patients were followed up between 6 to 24 months (mean 10 months).All patient survived at the end of study without the treatment of castration.Among 13 cases accepted NVB operation,8 cases achieve the preoperative level of erectile function to achieve.Conclusions The rate of incidental prostate cancer from RCP specimens is low,Most patients have low risk level,and there was no statistical significance of tPSA values between the incidental prostate cancer group and non risk group.

Objective To investigate the application value of perioperative enhanced recovery after surgery (ERAS) combined with laparoscopic common bile duct exploration (LCBDE) in the treatment of choledocholithiasis.Methods The clinical data of 84 patients with choledocholithiasis who were admitted to the Yijishan Hospital from January 2011 to December 2013 were prospectively analyzed.A single-blind,randomized,controlled study was performed in the 75 patients who were allocated into the control group and the enhanced recovery after surgery group (ERAS group) based on a random number table.All the patients underwent LCBDE,the patients in the control group received conventional perioperative management and the patients in the ERAS group received perioperative management according to enhanced recovery rehabilitation program.All the patients were followed up by outpatient interview till postoperative month 6.The clinical features,liver function and residual stones in the patients were observed.The operation time,postoperative complications,postoperative intestinal function recovery,duration of hospital stay and hospital expenses in the two groups were compared.Measurement data with normal distribution were presented as x ± s.Comparison between groups were evaluated with an independant sample t test.Count data were analyzed using the chi-square test.Results All the 75 eligible patients undergoing successful operation were randomly divided into the control group (35 patients) and the ERAS group (40 patients).The operation time and volume of intraoperative blood loss in the control group and the ERAS group were (185 ±46)minutes and (124 ±28)mL,(178 ±37) minutes and (114 ±32)mL,respectively,with no significant difference (t =0.729,1.431,P ＞ 0.05).There were 12,14 and 10 patients in the control group and 5,6 and 4 patients in the ERAS group with postoperative incision pain,vomit and infection,showing a significant difference (x2=5.054,5.966,4.241,P ＜ 0.05).The level of white blood cell,alanine aminotrausferase and direct bilirubin in the control group and in the ERAS group were (11.4 ± 3.5) × 109/L,(128 ± 33)U/L,(38 ±14) μmol/L and (10.6 ± 3.0) × 109/L,(135 ± 35) U/L,(44 ± 16) μmol/L at postoperative day 1,compared with (7.8 ±2.9) × 109/L,(48 ± 14) U/L,(21 ± 8) μmol/L and (6.9 ±2.1) × 109/L,(43 ± 13) U/L,(20 ±7) μmol/L in the 2 groups at postoperative day 4,respectively,showing no significant difference between the 2 groups (t =1.018,-0.872,-1.767,1.553,1.836,1.044,P ＞ 0.05).The postoperative first flatus day,time of food intake,time of postoperative infusion and duration of hospital stay were (42 ± 13)hour,(45 ±14) hours,(6.8 ±2.3)days and (11.3 ±4.5)days in the control group,and (35± 11)hours,(19 ±7)hours,(4.2 ± 1.8) days and (9.6 ± 2.4) days in the ERAS group,with a significant difference between the 2 groups (t =2.741,10.524,5.485,2.077,P ＜ 0.05).The total hospital expenses was (18 729 ± 3 127) yuan in the control group,which was significantly greater than (16 981 ±2 756) yuan in the ERAS group (t =2.574,P ＜ 0.05).The liver function of all the patients was recovered at the postoperative month 1.Four patients with residual stones in the 2 groups were detected by T-tube cholangiography,and were cured by removal of gallstones by choledochoscopy.There were no complications of the abdominal pain,jaundice and fever in all the patients till the end of follow-up.Conclusion ERAS combined with LCBDE for the treatment of choledocholithiasis is safe and feasible,with the advantages of low morbidity,quick recovery,short duration of hospital stay and less hospital expenses.
