Objective Intestinal obstruction is a frequent sequela of recurrent ovarian cancer and difficult to deal with We analyzed a series of such patients to determine if their outcomes have changed after undergoing palliative surgery Method We retrospectively reviewed 67 patients undergoing surgery for intestinal obstruction due to recurrent ovarian carcinoma and 75 patients receiving non surgical treatmen from 1997 to 2002 Results During the study period,67 operations were performed on 67 patients Among them,surgical procedure was completed in 58 cases Successful palliation was achieved in 64 2% of cases in which surgical correction was possible The median survival of the entire cohort was 7 8 months,and 12 6 months for the surgically successfully relieved patients and 3 7 months for those non surgical patients The rate of major surgical morbidities was 22 4 % The perioperative mortality rate was 6 0% Successful palliation was associated with the absence of two prognostic factors:multiple obstructive sites and palpable abdominal and pelvic masses Conclusion Palliative surgery for bowel obstruction in recurrent ovarian cancer can be worthwhile,and properly selected patients are the key to its success

Objective Potassium channel is essential for excitability of neurons and is involved in the regulation of information transmission. The purpose of this study was to investigate the effect of propofol on the voltage-gated potassium channels in rat hippocampal pyramidal neurons. Methods SD rats of 5-15 days old were decapitated and brain was immediately removed. Hippocampal pyramidal neurons were freshly isolated. Whole-cell patch clamp recordings were made. Voltage-dependent sodium and calcium currents were inhibited by TTX 1?mol?L-1 and CdCl2 400 ?mol?L-1 added to the perfusate. The effects of propofol on transient outward potassium currents and delayed rectifier potassium currents were studied and also the kinetics of channels. Results All the channels studied were reversibly inhibited by propofol in a dose-dependent manner. EC50 of propofol on transient outward potassium channels and delayed rectifier potassium channels were (71?18) ?mol?L-1 and (37?18) ?mol?L-1 respectively. The maximum inhibition rates were 52%?3% and 32%?5% .Conclusion Propofol reversibly inhibits potassium currents in a does-dependent manner. It is inferred that propofol affects the excitability of hippocampal neurons.

Objective To observe the clinical effect of combination of clopidogrel and simvastatin on coro-nary heart disease and transient ischemic attack(TIA). Methods 76 patients with coronary heart disease and TIA were randomly divided into test group (n=40) and control group (n=36). The control group was treated with en-teric-coated aspirin 50 mg×2 every night after supper, and the test group was treated with clopidogrel 25 mg×2 and simvastatin 10 mg×2 every night before sleep. Liver and kidney function, blood coagulation function and blood lipids were measured before treatment and after. 1 year followed-up. Results The effective rate was 95.0% (38/40) in test group and 55.5% (20/36) in control group(χ2=6.45,P<0.01). LDL-C was (3.18±1.24) mmol/L and (2.60±1.03)mmol/L(t=2.67,P<0.01),TC was(5.18±1.24) mmol/L and (4.02±2.18) mmol/L(t= 4.91, P<0.01),TG was (1.50±1.02) mmol/L and (1.30±1.03) mmol/L(t=1.02, P>0.05), respectively in test group before and after treatment. However, there was no statistical difference in LDL-C, TC and TG (t=0.17, 0.00,0.52,0.57,P>0.05 for each) in control group. The two groups showed no difference after treatment (t= 1.51,2.55,0.57, P>0.05 for each). Conclusions Glopidogrel combined with simvastatin capsules is safe in pre-vention of TIA attack.

Tissue engineering may allow obtaining patient’s own cells, seeding them on biodegradable scaffolds, thus achieving formation of a particular tissue or organs, such as bone, cartilage, muscle, or heart. These tissues or organs can be used to repair tissue or organs defects caused by disease or trauma. Many animal studies have demonstrated the efficacy of using bone marrow mesenchymal stem cells in treatment of diseases such as nervous system diseases, liver disease, respiratory diseases and kidney disease. The main ways of the stem cells therapy are local implantation and systemic transplantation of bone marrow mesenchymal stem cells, and the effect of such treatments is notable. The use of gene-modified stem cells in gene therapy is an fantastic option due to theoretical advantage of stem cells compared to somatic cells with respect to higher proliferative capacity. Bone marrow mesenchymal stem cells can deliver genes and proteins into organs or tissues with specific need for gene therapy.

Objective To introduce our experience in embolizing cerebral ruptured-aneurysms of elderly patients in our hospital. Methods Totally 76 elderly patients were referred to our hospital due to ruptured-aneurysms.81 aneurysms were confirmed by DSA,all of them were sac aneurysms,among which 75 cases (body/neck≥ 1) were treated with balloon-assisted coiling,29 narrow-necked (body/neck≥2) aneurysms and 30 wide-necked (1 ≤ body/neck＜ 2) aneurysms were treated with balloon-assisted coiling successfully,but 6 narrow-necked (body/neck≥2) were treated with balloonassisted coiling in emergency,followed by a stent-assisted coiling in secondary embolization,4 cases with body/neck＜1 were treated with stent-assisted coiling technique in emergency,2 non ruptured aneurysms could not be treated.The times of balloon dilation were (2.1 ± 1.3),single expansion of filling was (33.4±14.1)s. Results The arterial thrombosis happened in two patients (2.7 ％),two aneurysms ruptured (5.3％) during the procedure. No stent-related thrombosis happened. 86were elevated as good,8 as serious according to the Glasgow outcome scale,neither died after operation or delayed thrombosis or infarction lesion during following up. Conclusions Balloonassisted coiling is a safe and effective method in elderly patients during acute stage of rupturedaneurysms.

Objective To preliminary investigate fetal left heart function of fetuses in α-thalassemia using spatio-temporal image correlation (STIC).Methods 95 volumes from fetal hearts in singleton pregnancies at 20-28 weeks of gestation were collected.STIC datasets were frozen in end-systole and enddiastole.Ventricular volumes were measured using VOCAL,Inversion and SonoAVC.The stroke volume was calculated from these measurements.Results All data sets could be measured with all three techniques in this study.The intraclass correlation coefficients (ICCs) between techniques were all ＞ 0.90.The time necessary to measure the stroke volume was significantly shorter using SonoAVC than using VOCAL and Inversion.Bland-Altman plots showed no clinically significant mean percent differences between stroke volume measurements obtained from each ventricle using three techniques.The left ventricular end-systole volume(ESV),stroke volume(SV)and ejection fraction(EF)was significantly different than fetuses with normal heart (P ＜ 0.05).Conclusions This study shows the feasibility of measuring left ventricular volumes during either systole or diastole and thereby calculating stroke volumes with all three techniques.And there was a high degree of reliability for all three techniques,as shown by excellent ICCs.There was good accuracy of STIC techniques in measuring fetal left ventricular volumes with cardiomegaly.

Objective To evaluate the curative effect of percutaneous puncturing drainage in treating liver abscess,to analyze the factors affecting curative effect,and to discuss the methods ior reducing mortality and complication rate as well as for shortening hospitalization time.Methods Clinical data of 121 patients with liver abscess,who were admitted to authors' hospital during the period from January 2011 to January 2016,were retrospectively analyzed.For the patients with confirmed liver abscess,adequate antiinfective therapy was adopted,at the same time CT scan was performed to evaluate the liquefaction of lesion,and under CT guidance percutaneous puncturing drainage was carried out.The mortality,complication rate,hospitalization time and the factors affecting curative effect were analyzed.Results A total of 121 patients with liver abscess were enrolled in this study.Two patients died after percutaneous puncturing drainage,the mortality was 1.6％.The factors affecting mortality included old age,underlying disease,the diameter and solid components of abscess.Two patients developed peripheral hepatic abscess and abdominal wall abscess,the complication rate was 1.6％,and clinical cure was achieved after active treatment in these two patients.The main factor affecting complication rate was inappropriate surgical manipulation.Clinical cure was achieved in all 119 patients,with a cure rate of 98.3％,and the average hospitalization time was (15.1±6.0)days.The risk factors that affected hospitalization time included the number of abscess X6 (r=0.232,P=0.021),abscess size X7 (r=0.26,P=0.005) and white blood cell count X8 (r=0.238,P=0.009).Multiple linear regression equation analysis indicated that statistically significant correlation existed between the above influence factors and hospitalization time (P＜0.05).The multiple regression equation was as follows:Y=-3.438+3.055X6+0.527X7+0.297X8,F=5.819,R2=0.416.No statistically significant correlation existed between the hospitalization time and other factors,including gender,age,diabetes mellitus,pathogenic bacteria and location of abscess (P＞0.05).Conclusion Percutaneous puncturing drainage is an effective treatment for liver abscess,it carries lower mortality and lower complication rate,and its hospitalization time is short.(J Intervent Radiol,2017,

BACKGROUND:It has been demonstrated that shortening of femoral eccentricity would lead to decreased abductor muscle strength,and overlengthening eccentricity would increase the risk of femoral neck prosthesis fracture and the compressive stress of cemented femoral stem prosthesis after artificial hip replacement,which easily causes prosthetic loosening and subsidence.OBJECTIVE:To investigate the importance of eccentricity adjustment in the artificial hip replacement for treatment of femoral neck fracture in elderly patients.DESIGN,TIME AND SETTING:An observational study was performed at the Department of Orthopedics,First Affiliated Hospital of Tianjin University of Traditional Chinese Medicine between January 2004 and December 2005.PARTICIPANTS:A total of 30 patients with femoral neck fracture,12 males and 18 females,averaging 73.8 years of age (range 62-90 years old),received treatment at the Department of Orthopedics,First Affiliated Hospital of Tianjin University of Traditional Chinese Medicine and were recruited into this study.METHODS:All patients underwent artificial hip replacement operated by the same team of surgeons.Prior to surgery,some indices on the uninjured side were determined through the anteroposterior radiographs of pelvis using X-Caliper measurement tool,including rotation center of femoral head,rotation center of hip joint,collodiaphyseal angle,femoral transverse eccentricity,abduction moment arm,and moment arm of gravity.These indices were precisely calculated using trigonometric function.The angle of osteotomy plane was determined.Proper prosthesis was selected and eccentricity was adjusted.Following artificial hip placement,a comparison was made between uninjured and injured sides.MAIN OUTCOME MEASURES:Eccentricity and hip joint function.RESULTS:The eccentricity on uninjured side of 30 patients averaged 38.7 mm (range 22-57 mm) prior to surgery and that on the injured side averaged 39.2 mm (range 21-59 mm) after surgery.Limb discrepancy ranged 1.8-8.7 mm,with a mean of 3.4 mm,after surgery.There were 26 patients (86.7%) presenting long limbs and 4 patients (13.3%) showing short limbs after surgery.All patients were followed-up 0.5-2.5 years old.Harris hip score results were excellent in 10 patients,good in 19 patients,and fair in 1 patient,with an excellent and good rate of 97%.CONCLUSION:In treatment of femoral neck fracture,eccentricity adjustment during artificial hip replacement is closely associated with hip joint function after surgery.
