ObjectiveTo manage the early immunosuppressant-associated hypertention in liver transplantation patients. MethodsFifty-six liver transplantations were performed from May 2000 to May 2002, their clinical feature (data of blood pressure and treatment) were analysed. ResultThe incidence of hypertension after liver transplantation was 70% in 2 weeks, 66% in one month. The incidence in cyclosporine group and FK506 group was 73% (31/40) and 33%(3/9) respectively(P

BACKGROUND: The structural and functional changes in resistance arteriole of external diameter ＜300 μm is one of the pathological foundations for ischemic cerebrovascular diseases, however there are few quantitative study on the arterioles of various external diameter at different brain area.OBJECTIVE: To probe the difference of arteriolar sclerosis of various external diameter at different brain area after cerebral infarction.DESIGN: Sample investigation.SETTING: Department of Nerve Internal Medicine, General Hospital of Beijing Military Area Command of Chinese PLA.SUBJECTS: Specimen was taken from donated autopsy case in General Hospital of Beijing Military Area Command of Chinese PLA from January 1980 to September 2000. According to the clinical manifestation, brain CT inspection and pathological diagnosis of autopsy, 38 cases were defined as arteriosclerosis cerebral infarction and taken as experimental group, other 15 cases with non-cardiac cerebrovascular disease were taken as controls.METHODS: specimen was obtained in 1-3 days after death from frontal and parietal cerebral cortex and basal gonglion white matters (3 pieces /case) and cut into slices. Five fields of vision were selected from each slice for microscopic observation. Arteriole was divided into ＜ 50 μm group,50-100 μm group and ＞100 μm group according to the arteriole external diameter. (External diameter- internal diameter)/internal diameter was used to assess vascular sclerosis.MAIN OUTCOME MEASURES: [1] Difference of arteriole sclerosis between corresponding external diameter cerebral infarction group and control group. [2] Arteriole sclerosis in various brain region in cerebral infarction group.RESULTS: Totally 38 experimental cases died from arteriosclerosis cerebral infarction and 15 controls died from non-cardiac cerebrovascular disease were enrolled and all data was entered the result analysis. [1] The arteriolar sclerosis index was obviously higher in ＜ 50 μm external diameter cerebral infarction group than in 50-100 μm group and ＞100 μm group[(138.55±76.67)% vs (116.82±58.80)%, (78.07±32.06)%, P ＜ 0.01], while it was approximately the same in the 100 μm external diameter group and control group [(78.07±32.06)% vs (46.38±13.41)%, P=0.174 ]. [2] In ＜ 50 μm external diameter cerebral infarction group, the arteriolar sclerosis index in white matters was significantly higher than that in gray matter [(152.86±87.83)%,(127.97±64.76)%, P ＜ 0.05 ].CONCLUSION: Arteriolar sclerosis degree is correlated with its external diameter and position in patients with cerebral infarction after arteriosclerosis, arteriole of small external diameter or in the white matter has higher arteriolesclerosis liability.

Many kinds of volatile organic compounds(VOCs)exist in the indoor air,the chemical reaction will occur among the pollutants when O3 and NO2 exist simultaneously.This reaction can severely impact the indoor air quality and produce some adverse effects on human health.The main chemical reactions among the indoor air pollutants and the potential health effects associated with inhalation exposure to the products of the chemical reaction in the indoor air were discussed in the present paper.The study of the chemical reactions among indoor VOCs is very important for human health and is helpful for revising the Indoor Air Quality Standard and making the 'Ecologic Label' of building materials.

Objective This study was to detect protein expression of ERK 1,ERK 2,JNK 1,p38 and MEK 1 ,MEK 2 in human hepatocellular carcinoma and adjacent non neoplastic liver tissues.Method Western blot was used to detect the expression of ERK 1,ERK 2, JNK 1,p38 and MEK 1,MEK 2 in the surgically resected hepatocellular carcinoma and para carcinoma tissues in 16 HCC patients.[WT5”HZ] Result The expression of ERK 1,ERK 2,p38 expressed by integral optic density (IOD) in hepatocellular carcinoma was significantly higher than that in para carcinoma respectively: as for ERK 1 it was 300?98 in carcinoma and 98?48 in para carcinoma tissues ( P

Objective To study the causes and management of biliary complications after orthotopic liver transplantation.MethodsClinical data of 38 patients who have underwent orthotopic liver transplantation between May 2000 and January 2002 were studied retrospectively. ResultsPostoperative bililary complications occurred in 9 patients(24%), including simple biliary fistula in 4, stricture of hepatoenterostomy, intrahepatic cholelith, biliary stricture with sludge, biliary stricture with cholelith, and intrahepatic biloma and cholelith in one each. Two patients died of the complication, and seven were cured successfully. ConclusionsThe causes of biliary complications are complicated. Early diagnosis and timely management helps to decrease the mortality. Endoscopic retrograde cholangiopancreatography and percutaneous transhepatic cholangiography is a valuable, less traumatic procedure.

[Objective]To evaluate the long-term clinical results of Herbert screw in the treatment of intra-articular fractures by retrospective analysis.[Method]From 1991 to 2006,fifty-five patients of different parts of intra-articular fracture treated with Herbert screw were followed up effectively,including scaphoid fracture group of 19 cases,the radial head fracture group of 25 cases,the femoral head fracture group of 11 cases.[Result]After an average follow-up time of 5 years and 11 months(ranged,1-13 years),the good-to-excellent rates were 94.7%,96%,72.7% according to the modified Mayo score,the Broberg-Morrey score and the Tompson-Epstein score.[Conclusion]The Herbert screw can provide strong fixation and stability in the long-term follow-up.It is an ideal material in treating intra-articular fractures.

ObjectiveTo investigate the incidence of de novo malignancies in liver transplantation recipients.MethodsWe retrospectively assessed data of 475 patients undergoing liver transplantation from May 2000 to December 2008. ResultsAmong the 475 recipients followed-up for 6 months at minimum,5 patients developed de novo malignancy and the total incidence rate was 1.1％.The median elapsed time from transplant to the diagnosis of de novo malignancy was 14 months (range 6 to 72).The patients were all males,including one of rectal cancer which was cured by radical resection,2 of hepatocellular carcinoma who died 6 and 14 months respectively after the diagnosis,1 of neuroendocrine carcinoma of the lung dying after 16 months,1 of Bukitt lymphoma who died within 2 months.Conclusions De novo malignancy is an uncommon event in liver transplantation recipients,but the outome is very poor.

Objective To evaluate the prevalence and risk factors of posttransplantation metabolic syndrome(PTMS)in liver transplant recipients.Methods According to NCEP-ATP Ⅲ(2001)standard,we assessed for the presence of PTMS in 102 transplant recipients which have lived ≥ 5 yesrs after liver transplantation.Age ≥ 50 years,the male sex,history of smoking,preoperative obesity,preoperative hypertension,preoperative diabetes,and preoperative hypertriglyceridemia were selected for evaluation.Predictors for PTMS were tested using Logistic regression analysis.Results Among 102 patients assessed,the prevalence of PTMS was 51.9％ compared with 29.3％ pretransplant level.Obesity(body mass index ＞ 28 kg/m2),hypertriglyceridemia(＞ 1.7 mmol/L),high-density lipoprotein cholesterol ＜ 1.0 mmol/L(men)or ＜ 1.3 mmol/L(women),hypertension,and diabetes were significantly more common in patients after transplantation.The independent factors associated with PTMS were older age,preoperative obesity and preoperative diabetes.Conclusions PTMS is highly prevalent among transplant recipients,older age(＞ 50 years),preoperative obesity and preoperative diabetes are among the risk factors for PTMS.

From July 2006 to November 2008,16 patients with unstable intertrochanteric fractures were treated with cemented bipolar hemiprosthesis arthroplasty, including 5 males and 11 females, at a mean age of 84 years (range, 78-92 years) in the First Affiliated Hospital of Soochow University. Of them, 15 patients were followed with mean time of 14 months. The cemented bipolar hemiprosthesis was purchased from Beijing Montagne. The patients received 5-7 days of antibiotics following arthroplasty in addition to medicine of anticoagulation and analgesia. 1 case died of pulmonary heart disease 10 months after the operation and 3 cases had heterotopic ossification. There was no prosthesis loosening or dislocation. According to Harris hip scores, 3 cases were rated as excellent, 9 good, 3 fair, and 0 poor; the excellent and good rate was 80%. Results show that cemented bipolar hemiprosthesis arthroplasty is effective in treating elderly unstable intertrochanteric fractures, but operation indications require more attention.

Objective To summary the experience of living donor liver transplantation (LDLT) in order to improve therapeutic effect of LDLT. Methods We retrospectively analyzed the clinical data of donors and recipients of 22 LDLT cases, evaluating patients' and donors' preoperative assessment, surgical strategies and postoperative complications. Results Donor's grafts harvested included 2 left lateral lobes, 6 left half livers, 1 extended left half liver, 5 right half livers and 8 extended right half livers. Postoperatively all donors recovered without severe post-transplantation complications. Among 13 adult and 9 child receipients, there were 8 recipients suffering from posttransplantation complications, including intra-abdominal severe infection in one case, delayed liver function recovery complicating incisional infection in one case, intra-abdominal hemorrage complicating thrombogenesis of the hepatic artery in one case. All these 3 patients died. One child recipient of hepatic failure died of heart and respiratory failure after operation. Other non-lethal complications were bile leakage in 2 cases, refractory ascites in one and deep venous thrombosis of the lower limb in one. These complications were cured without laparotomy. Finally 18 recipients were fully recovered and discharged. Late post-operative complications included strictures of biliary tract in 3 cases which were treated with PTCD and indwelling stent, the obstructive jaundice due to achalasia of sphincter of Oddi was treated with endoscopic sphincterotomy. These 4 patients' are on stable condition and the liver function is normal. Conclusions Select proper donor and optimal surgical strategy are extremely helpful to secure donors and recipients during the procedure of LDLT.
