Objective:To probe the correlation of intra-operative hyaluronic acid(HA) changes with hepatic allografts cold ischemia reperfusion injury in liver transplantation.Methods:The patients with orthotopic liver transplantation were assigned to 3 groups:① group A :liver allografts were stored in University of Wisconsin's solution(0℃) for 5-6 h before implantation;② group B :liver allografts were stored in U W's solution(0℃) for 8-9 h before implantation;③ group C :liver allografts were stored in U W's solution(0℃) for 12 h before implantation.The serum samples were taken up at 5 min,60 min,120 min,180 min after the donor liver was transplanted and reperfused to detect the concentration of HA.Results:After donor liver was transplanted and reperfused,serum HA concentration decreased immediately and gradually.HA decreased rate :group A 4.58 ?g/L?min-1,group B 4.16 ?g/L?min-1,group C 2.26 ?g/L?min-1.Serum HA decrease rate was faster in group A and B than that in group C(P
2.Current status on the intestinal barrier dysfunction in HIV infection
Parenteral & Enteral Nutrition 2017;24(4):244-248
Highly active antiretroviral therapy (HAART) can effectively suppress thehuman immunodeficiency virus (HIV) replication andsignificantly reduce morbidity and mortality of HIV-infectedpatients,which howevercan't completely remove the virus,and eventually progressinto chronic viral-infection disease.Chronic HIVinfection destroys host immune system,leading to intestinal barrier damage,intestinal mucosal dysfunction,microbial translocation,and further accelerates the disease progress.The reconstruction of intestinalmicroflora balance and improvement of intestinal mucosa function areessential to reestablish the host immune system.This paper will review the current research advanceson intestinal barrier damage of HIV infection and gut-target therapy of AIDS.The aim is to provide valid evidences for further research targeting improvement of treatment strategiesandreduction of morbidity and mortality in HIV infection.

Objective To evaluate the effect of cold ischemia on the expression of tumor necrosis factor alpha (TNF-?) and interleukin-10 (IL-10) and hepatic regeneration in liver grafts.Methods Partial liver transplantation model in rats was developed. The rats were divided into 3 groups: control group receiving 50 % liver resection,experimental group 1 receiving partial liver transplantation 30 min after cold ischemia and experimental group 2 receiving partial liver transplantation 10 hr after cold ischemia. The expression of the proliferative cell nuclear antigen (PCNA),TNF-? and IL-10 in liver tissues obtained on the postoperative day 1,2 and 4 in rats was detected by using immunohistochemical method. Correlation analysis was performed on the liver proliferation and regeneration,and the expression of TNF-? and IL-10.Results The survival rate in control group,experimental group 1 and experimental group 2 was 100 % , 79 % and 29 % respectively. In the experimental group 2,the expression of PCNA,TNF-? was significantly decreased,while the expression of IL-10 increased as compared with that in experimental group 1 (both P

Objective To summarize experience of selection of donors of living related liver transplantation (LRLT) for Wilson’s Disease.Methods Twenty-nine cases of Wilson’s disease were subjected to LRLT in our center. A retrospective data analysis was carried on 70 potential donors. Results Twenty-three of the 70 potential donors were excluded. The causes were as follows: family and traditional background (n=10, 43.5 % ), copper metabolism abnormality, serum ceruloplasmin 100 ?g (n=6, 26.1 % ), hepatic steatosis (n=4, 17.4 % ) and hepatitis B (n=3, 13 %). The grafts were right liver (n=10) and left liver (n=19). Graft-recipient weight ratio was ( 1.38 ? 0.44 ) %. All donors recovered completely. Perioperative surgical complications occurred in 3 donors and were cured without reoperation, temporary biliary leakages (n=2) as well as postoperative bleeding from the wound of liver (n=1). Conclusions Major impact on living relative donors for Wilson’s Disease is traditional background, copper metabolism abnormalities, hepatitis B and hepatic steatosis. Comprehensive preoperative evaluation of potential donors and harvesting liver surgery innovation ensure the donor safety and graft quality.

Objectives To study the influential factors of the von Clauss method and to promote the method for fibrinogen assay in clinical laboratories in China. MethodsKits of foreign and domestic products were used. Calibration curves for fibrinogen determination were established, and calibration plasma was used for comparison. Effects of pH value, thrombin activity, and temperature on the measurement were studied.Results The reproducibility of the von Clauss method using domestic thrombin and related reagents was excellent, the within day CV being 0.039 1, and the between day CV 0.049 7. The percentage variations of calibration plasma determination, with the foreign fibrinogen assay kits using domestic reagents, were +3.17% , +4.76%, and -6.03%, respectively. Determination of a lyophilized plasma using the two sources reagents showed similar results.Conclusions Thrombin and relevant reagents produced in China could be used as a substitute for kits purchased abroad, which would promote the use of von Clauss method in clinical laboratories of China.

Objective To explore the improvement of traditional incision in thoracotomy and the application of subaxillary vertical small incision in lung operations. Methods We carried out a retrospective analysis on documents of 680 cases of subaxillary vertical small incision pneumonectomy conducted in this hospital between December 1996 and June 2003. Results The length of incision was 8~13 cm (mean, 11 2 cm). The time for thoracotomy was 4 5~10 min (mean, 6 min) and the operation time was 50~ 170 min (mean, 135 min). The intraoperative blood loss was 100~1200 ml (mean, 350 ml), the postoperative drainage volume was 120~800 ml (mean, 300 ml), and the perioperative blood transfusion, 0~1400 ml (mean, 300 ml). Postoperative pain classification results revealed that 585 cases of grade 1, 60 cases of grade 2 and 35 cases of grade 3 severity were observed. The postoperative hospital stay was 10~21 days (mean, 14 days). No surgical death occurred. Conclusions Subaxillary vertical small incision can be simply made. It offers minimal invasion, less blood loss, mild postoperative pain, quick recovery and good cosmetic results, being a viable option in most operations of pneumonectomy.

Objective To discuss the diagnosis and surgical management of pulmonary sclerosing hemangioma(PSH).Methods Clinical records of 33 cases of PSH(34 lesions) in this hospital from 1987 to 2002 were reviewed.There were 6 male cases and 27 female cases,with a mean age of 41.3 years(range,24~57 years).Twenty-three cases had an initial symptom of bloody sputum,while 10 cases were disclosed by physical examinations.Image findings revealed solitary mass of the lung in all the cases,in 5 of which a "crescent sign" was presented.Results Preoperatively,28 cases were diagnosed as having pulmonary benign tumors(including 5 cases of suspected sclerosing hemangioma),1 case was clarified as having PSH by percutaneous needle aspiration cytology,and 4 cases were misdiagnosed as having lung cancer. All the patients received surgical treatment,including 21 cases of unilateral pulmonary lobectomy,1 case of bilateral lobectomy,5 cases of segmentectomy,4 cases of wedge resection(including 1 case of bilateral thoracoscopic wedge resection),and 2 cases of tumor excision.The operation time was 45~210 min(mean,90 min),and the blood loss was 100~600 ml(mean,230 ml).No peri-operative deaths were encountered.Follow-up surveys in 33 cases for(3~)10 years(mean,5.5 years) found no recurrence.Conclusions In middle-aged women,if the sign of bloody sputum develops,and image findings indicate the solitary mass of the lung,especially with a "crescent sign",a diagnosis of PSH is possible.Percutaneous needle aspiration cytology is helpful to make a confirmative diagnosis in some patients.It is advisable to manage the disease surgically.

Attention deficit hyperactivity disorder(ADHD) and developmental coordination disorder(DCD) are both childhood disorders identified in the DSM-Ⅳ.Studies investigating ADHD have found that around half of ADHD cases also have motor problems severe enough to be diagnosed as DCD.Further,children initially diagnosed as DCD have also been found to meet moderate to severe diagnosis for ADHD.Both disorders have been linked to a lot of psychosocial problems.Furthermore,when ADHD and DCD are co-morbid,the outcome tends to be more severe than when either disorder occurs alone.In the past decade,many studies identified shown that ADHD children experienced difficulties with both fine motor movements and gross motor movements.Notably,most of these foregoing studies found balance functions of ADHD were impaired.In order to maintain balance under a verity of environmental conditions,sensory information from somatosensory,visual,and vestibular origins must be integrated by the central nervous system.But there are rich evidences suggesting that children with ADHD can not organize the motor information effectively.The maintenance and control of posture and balance,whether in static or dynamic conditions,are essential requirements for daily activity.The balance function has been closely associated not only with both gross motor movements,such as sitting,standing,walking and fine motor movements,but also with human behaviors.There are increasing evidences suggesting that balance deficit correlates with symptoms of ADHD.Therefore,motor coordination difficulties co-occurring with ADHD should be given emphasis in clinical practice;the training of balance may be one of the possible methods to improve the motor coordination function in ADHD children.
