Hepatic myelopathy is a rare disease with high mortality. There has been no report of an effective treatment to date. In order to evaluate the beneficial effect of orthotopic liver transplantation in patient with hepatic myelopathy. One patient, who was suffering from hepatie myelopathy complicating hepatic pathology, underwent liver transplantation in 2002 was studied. The muscle strength of the patient’s extremities was carefully assessed both pre-operatively and postoperatively. It was found that symptoms and signs of hepatic myelopathy were improved, especially the muscle strength recovered from 1-2 degree to 3-4 degree half a year after the operation. Therefore it is our belief that liver transplantation might be beneficial to patients who are suffering from hepatic myelopathy as a complication of the hepatic disease.

Objective To observe the therapeutic effects and side-effects of tacrolimus (FK506) in the recipients who had undergone liver transplantation, and summarize the clinical experience of its use. Method The clinical data of 36 recipients of allogeneic liver transplants followed by tacrolimus-based anticoagulant regimen were retrospectively analyzed. After liver transplantation, all the recipients received the triple-drug immunosuppressive protocol, including tacrolimus as the basic drug, mycophenolat-mofetil (MMF), and prednisone. Twenty-four of 36 cases received Zenapax as an antibody induction therapy. Results Acute rejection occurred in 3 of 36 cases. After the use of methylprednisolone and OKT3, acute rejection was reversed. The main side-effects of tacrolimus were nervous system disturbance(40.0%), hypertension(13.3%), hyperglycemia(26.7%), and liver dysfunction(6.7%). Conclusion Tacrolimus is a safe and potent immunosuppressive agent, which can decrease the incidence of rejection in liver transplant recipients. The dosage of tacrolimus should be adjusted according to trough level with in the therapeutic window. The timely and appropriate adjustment of the immunosuppressive strategy is essential for the recipient and graft survival. Meanwhile, it is emphasized that the regime should be individualized.

Objective To exploration the value of color Doppler ultrasounographhy(CDU) in the diagnosis of breast mass. Methods The clinical data of 600 cases of breast tumor treated in our hospital in recent 3 years were retrospectively analysed, all patients were examined with CDU before operation. Results CDU found breast small tumor in 163 cases(27.2%) which couldn’t detected by hands, found multiple masses in 307 cases(51.2%);and suspected malignancy in 75 cases,of the 75 cases,malignancies were comfirmed by pathological examination in 72 cases(96.0%).Conclusions CDU can find small breast mass which can not be detected by hands,and can determin the mass is a tumor or not.CDU can also find early stage of breast cancer.CDU is non-traumatic,rasily to be perfomed and repeated.CDU can improve the preoperative diagnosis rate of breast mass.

Objective To investigate the levels of blood sugar and electrolyte in nonage of 125 patients with liver transplantation.Methods According to the parameters of blood sugar and electrolytes,the usage of insulin and electrolyte was adjusted whenever necessary.The levels of blood sugar and electrolytes were maintained respectively in 6～10 mmol/L and normal limits.The oxygen inhalation,antibiotics,immunosuppressant,liver protectant,diuretics and vasodilators were also used in the preoperative period.Results Of 125 cases of liver transplantation recipients,there were 50(40%) cases with blood sugar heightened remarkably.Massive potassium chloride and sodium chloride was used to keep electrolytes in normal limits.Conclusion The levels of blood sugar and electrolytes are not stable in nonage of liver transplantation and it is very important to maintain them in normal limits for the success of liver transplantation.

BACKGROUND: Hepatic myelopathy results from liver disease, which lacks of effective cure method. Liver transplantation has attempted to cure this disease; however, the long-term therapeutic effect is rarely reported. OBJECTIVE: To explore the long-term therapeutic effect of liver transplantation in patients with hepatic myelopathy. METHODS: The clinical data of 2 patients with hepatic myelopathy, who underwent orthotopic liver transplantation, in August 2002 and November 2004, at the 309 Hospital of Chinese PLA, were analyzed retrospectively. The time of follow-up was 18 and 43 months, respectively. The muscle strength of double lower limbs in 2 patients was assessed prior to and after operation. RESULTS AND CONCLUSION: Two patients recovered well at 4 weeks after transplantation, the clinical symptom and physical signs of patients were improved obviously, the blood routine examination and other biochemical index were normal,and the function of transplanted kidney was normal. Two patients discharged at 6 weeks after transplantation. Patient 1 could stand for a long time at months 6 after transplantation, walked slowly with the supporter after 12 months and without the supporter at 43 months. The muscular strength of two lower limbs was grade 4. And the liver function was normal. Patients 2 could move his lower limbs in bed at months 6 after transplantation, walked with the supporter at 18 months. The muscular strength of two lower limbs was grade 3. The liver function was normal. It demonstrated that liver transplantation is beneficial to control hepatic myelopathy and recover muscular strength of two lower limbs. It is a newly developed, effective curing method for treating hepatic myelopathy. However, the numbers were small with short time observation, thus, the long-term therapeutic effect still need to be explored.

Objective To explore the roles of B lymphocyte and plasma cell in liver allograft re-jection to find the evidences of humoral factor participating in the rejection. Methods Immunohisto-chemical inspection of C4d, CD20+ B lymphocytes and CD138+ plasma cells were performed in 34 liver biopsy specimens from 25 patients with hepatic injury and their preoperative specimens. Then we ob-served the variances of the above parameters in the liver biopsy specimens and the differences of them with different hepatic injuries. We further observed the relation of the presence of CD20+ B lympho-cytes and CD138+ plasma cells to C4d positivity. Meanwhile, we compared the difficulties of clinical therapy with different presences of CD20+ B lymphocytes and CD138+ plasma cells in the liver biopsy specimens. Results The positive ratios of CD20+B lymphocytes and CD138+ plasma cells were signif-icantly higher in the acute rejection group than in the non-rejection group(P<0. 05 and P<0. 01).The positive ratios of CD20+ B lymphocytes were markedly higher in the chronic rejection group than in the non-rejection group(P<0. 05). There was no difference in CD138+ plasma cells between the 2 groups. The degrees of hepatic injury could not influence the positive ratioes of CD138+ plasma, but the positive ratioes of CD20+ B lymphocytes in the heavy hepatic injury groups was higher than in the slight hepatic injury groups(P<0. 05). CD20+ B lymphocytes and CD138+ plasma cells presented fol-lowing C4d(P<0. 01 and P<0. 05). The effective power of steroid in the all-positive group was obvi-ously lower than in the all-negative group(P<0. 05). Conclusion Humoral immune may participate in some liver allograft rejection. It would be more favorable for observing and prewarning the humoral re-jection by finding CD20, CD138 and C4d by immunohistochemical staining in liver biopsy specimens with hepatic injury after liver transplantation. It would be helpful for choosing the therapeutic regi-mens of liver allograft rejection.

Objective To assess the value of preoperative neutrophil-lymphocyte ratio ( NLR) for predict the prognosis in patients with high grade T1 bladder.Methods From January 2004 to December 2014, the data of 307 patients diagnosed as bladder cancer of Stage 1 and high grade after undergoing TURBT were analyzed, including gender, age, smoking status, tumor number and size, hydronephrosis, intravesical instillations and preoperative blood transfusion of 307 patients diagnosed as bladder cancer of stage 1 and high grade after undergoing TURBT were analyzed retrospectively.All patients were primary urothelial carcinoma.According to preoperative NLR,patients were divided into the low NLR group( NLR≤2.42,n=197) and the high NLR group(NLR >2.42,n =110).Recurrence-free survival (RFS) and progression-free survival ( PFS) were calculated according to the Kaplan-Meier model and compared by the log-rank model.Cox regression models were used for multivariate analyses of the association between NLR and bladder cancer, then the prognostic factors affecting RFS and PFS were evaluated.Result of these 307 patients, the low NLR group accounted for 64.2%(197/307), and the high NLR group accounted for 35. 8%(110/307).The mean follow-up period was 71(range, 1-123)months.The recurrence rate in the low NLR group and the high NLR group recurrence rate were 19.2%( 38/197 ) and 34.5%( 38/110 ) respectively, RFS were 73.0(range, 2-123)months and 67.5(range, 1-122)months respectively.The progression rates were 4.1%(8/197) and 10.9%(12/110) respectively.The recurrence and progression rates in the high NLR group is higher than those in the low NLR group(P<0.01 and P=0.008), and RFS was shorter( P=0.002).Multivariable Cox regression analysis showed that NLR>2.42(P=0.007,HR=1.912)and hydronephrosis (P<0.01, HR =2.485 ) are associated with higher risk of recurrence.Conclusion Elevated preoperative NLR is an independent predictor of RFS and PFS in patients with high grade T1 bladder cancer.

Objective To discuss the causes of failure of transpedicular screw fixation in treatment of thoracolumbar fractures. Methods A retrospective analysis was done to analyze the failure causes of 24 patients (15 males and 9 females) who received pedicle screw fixation for their thoracolumbar fractures from June 2002 to June 2008 in our department. There were two patients with delayed infection, eight with pedicle screw breakage, one with connecting rod breakage, 10 with internal fixation loosening (including nut loosening) and three with poor screw position. Results All patients received reo-perations including removal of internal fixation plus debridement and lavage in two patients, simple removal of internal fixation in nine patients, removal of inter fixation and posterior fusion in two, replacement of the lengthened fixation plus posterior fusion in nine, and adjustment of the position and orientation of screw in two. All patients were followed up for 6-18 months (average 11 months) , which showed no any complications. Conclusion Improper surgical indication or approach, ineffective fusion, incorrect postoperative rehabilitation exercise, too late removal of the screws and improper surgical operation are main causes for failure of internal fixation.

Objective:To explore the safety and efficiency of percutaneous coronary intervention (PCI) in maintenance hemodialysis patients combined with non-ST-segment elevation acute coronary syndrome (NSTE-ACS).Methods:The clinical data of 52 maintenance hemodialysis patients combined with NSTE-ACS from January 2010 to January 2015 in Dalian Central Hospital were retrospectively analyzed. Among of them, 25 patients were treated with common drugs (control group), and 27 patients were treated with common drugs combined with PCI (PCI group). The major adverse cardiac events (MACE) duration of hospital stay were record, including hemorrhage, malignant arrhythmia, new heart failure or aggravation, stroke and all-cause death. The dialysis complications within 1 month after treatment were recorded, including hypotension, arrhythmia, heart failure and angina pectoris. The patients were followed up for 12 months, the MACE 1, 6 and 12 months after treatment were recorded, including angina pectoris, heart failure and cardiac death.Results:Duration of hospital stay, the incidences of malignant arrhythmia and new heart failure or aggravation in PCI group were significantly lower than those in control group: 18.5% (5/27) vs. 44.0% (11/25) and 7.4% (2/27) vs. 32.0% (8/25), and there were statistical differences ( P<0.05); there were no statistical difference in the incidences of hemorrhage, stroke and all-cause death between the two groups ( P>0.05). The incidences of dialysis complications such as hypotension, arrhythmia, heart failure and angina pectoris within 1 month after treatment in PCI group were significantly lower than those in control group: 24.0% (6/25) vs. 56.5% (13/23), 16.0% (4/25) vs. 43.5% (10/23), 12.0% (3/25) vs. 47.8% (11/23) and 24.0% (6/25) vs. 52.2% (12/23), and there were statistical differences ( P<0.05 or <0.01). The follow-up results showed that the incidences of angina pectoris and heart failure 1, 6 and 12 months after treatment in PCI group were significantly lower than those in control group, angina pectoris: 28.0% (7/25) vs. 65.2% (15/23), 29.2% (7/24) vs. 76.2% (16/21) and 43.5% (10/23) vs. 17/17, heart failure: 16.0% (4/25) vs. 43.5% (10/23), 8.3% (2/24) vs. 33.3% (7/21) and 21.7% (5/23) vs. 10/17, and there were statistical differences ( P<0.05 or <0.01); there was no statistical difference in the incidence of cardiac death 1 and 6 months after treatment between two groups ( P>0.05), the incidence of cardiogenic death 12 months after treatment in PCI group was significantly lower than that in control group: 8.6% (2/23) vs. 9/17, and there was statistical difference ( P<0.01). Conclusions:PCI is safe and effective for maintenance hemodialysis patients combined with NSTE-ACS.

Objective To analyze the clinical and pathological features of advanced colorectal serrated adenoma(ACSA). Methods The endoscopic and pathological features of 156 cases of ACSA and 121 cases of non-ACSA diagnosed in General Hospital, Tianjin Medical University from January 2010 to March 2016 were retrospectively analyzed and compared.Results ACSA and non-ACSA cases accounted for 56.3%(156/277)and 43.7%(121/277)of all patients with colorectal serrated lesions,respectively. The mean age of ACSA patients was 57.79±13.65 years and 89(57.1%)of these patients were male. There was no significant difference in age and gender between ACSA and non-ACSA patients. A total of 161 ACSA lesions were diagnosed,including 71 sessile serrated adenoma/polyps and 90 traditional serrated adenomas. Among the 161 ACSA lesions,there were 29(18.0%)lesions whose diameter≥10 mm, and 84(52.2%) lesions located in the proximal colon, which were more than non-ACSA(84/161 VS 49/134,P=0.007). ACSA was classified under endoscopy into pedunculated type(20/161),sub-pedunculated type(35/161), sessile type(24/161),flat type(79/161)and laterally spreading tumor(3/161), and the distribution of lesion type was significantly different from non-ACSA(P<0.001). One hundred and sixty(99.4%)ACSA lesions were diagnosed as dysplasia, including 158 low degree dysplasia and 2 high degree dysplasia.Moreover,16 ACSA patients were accompanied with synchronous advanced colorectal neoplasia(sACN), and large serrated polyps(diameter≥10 mm)might have a strong association with sACN(OR=4.35, 95%CI:1.467-12.894, P<0.05). Conclusion ACSA is more common in proximal colon and sub-pedunculated type,sessile type and flat type. ACSA diameter≥10 mm is significantly associated with sACN.
