Objective To evaluate the effect of ulinastatin on hepatic ischemia-reperfusion injury in patients with hepatic alveolar echinococcosis in plateau region.Methods Sixty patients with hepatic alveolar echinococcosis in plateau region,weighing 45-75 kg,aged 30-55 yr,of American Society of Anesthesiologists physical status Ⅰ or Ⅱ,scheduled for elective partial hepatectomy,were divided into control group (C group) and ulinastatin group (U group) using a random number table,with 30 patients in each group.Ulinastatin 12 000 U/kg (in 100 ml of normal saline) was infused intravenously at 20 min before occlusion of hepatic portal in group U,and normal saline 100 ml was given instead in group C.Before operation,at 10 min after occlusion of hepatic portal,at 20 min and 1 h after unclamping hepatic portal and at 12 h after operation,blood samples were collected from the right internal jugular vein for determination of the levels of serum alanine aminotransferase,aspartate aminotransferase and malondialdehyde.Results Compared with group C,the levels of serum alanine aminotransferase,aspartate aminotransferase and malondialdehyde were significantly decreased at 20 min and 1 h after unclamping hepatic portal and 12 h after operation in group U (P＜0.05).Conclusion Ulinastatin can attenuate hepatic ischemia-reperfusion injury in patients with hepatic alveolar echinococcosis in plateau region.

Objective: To study the correlations between galectin-3, soluble ST2 (sST2) levels and chronic heart failure (CHF) classiifcation, traditional HF indicator and short-term death in relevant patients. Methods: This research included 2 groups: CHF group, containing 142 relevant patients treated in our hospital from 2014-02 to 2015-10 and Control group, containing 85 normal subjects from physical examination at the same period of time. Based on NYHA criterion, the patients were classiifed in NYHA grade II, III and IV respectively. Blood levels of N-terminal brain natriuretic peptide (NT-ProBNP), high-sensitivity C reactive protein (hs-CRP) and ultrasonic morphology were examined upon admission; protein expressions of galectin-3 and sST2 were assessed by ELISA. Results: The patients with NYHA grade III and IV had increased levels of galectin-3 and soluble sST2; galectin-3, sST2 were positively related to NT-ProBNP, hs-CRP and LVEDD, while negatively related to LVEF. Logistic regression analysis indicated that galectin-3 and sST2 were related to short-term death in CHF patients,P<0.05. Area under ROC curve of galectin-3 and sST2 for diagnosing CHF were 0.738 and 0.771,P<0.01. Conclusion: Galectin-3 and sST2 levels were related to traditional HF indicator and could be used for CHF diagnosis in relevant patients.

SUMMARY In this article , different methods to deal with teeth fractures were discussed by presenting a case of traumatic crown-root fracture in the anterior esthetic zone .The traumatic crown-root fracture is a common problem in clinic .When a fracture line locates in close proximity to or below the alveolar bone crest , the fracture most likely involve the junctional epithelium and the connective tissue attachment .This type of fracture becomes a challenge for restorative dentists because it involves biologic , functional , and es-thetic considerations , especially when the fracture occurs in an esthetic area .In this case , a young patient presented with two fractured upper anterior teeth to the Department of Periodontics , Peking University School and Hospital of Stomatology .After the comprehensive clinical evaluation , the right central incisor was decided to extract for implant therapy and the right lateral incisor was decided to retain by one modified crown lengthening surgery .The most common technique applied to save a retained root is a clinical crown lengthening procedure .However , the aggressive alveolar bone resection of both target and adjacent teeth to reestablish the bone width and periodontal health may compromise functional and esthetic outcomes .To re-duce loss of excessive osseous tissue during osteotomy procedure , the modified crown lengthening of the right lateral incisor was performed , including minor bone resection and root reshaping .Regarding the right central incisor , the retained root was all located below the alveolar bone crest .The extraction and implant procedure , combined with guided bone graft were performed to avoid the damage to neighbor teeth during traditional restorative therapy and to reshape a preferable buccal contour .At the last visit , the patient was recalled with healthy periodontium , normal tooth function and favorable esthetic results .

AIM: To investigate the effect of PMA(phorbol 12-myristate 13-acetate) on the expression of CD18 and the mechanism. METHODS: The technique of quantitative RT-PCR analysis was used to measure the expression of CD18 mRNA in U937 cells treated by PMA. RESULTS: PMA could significantly induce CD18 mRNA expression in a dose and time-dependent manner. The induction effects of PMA on CD18 mRNA could be inhibited obviously by Myr (2 ?mol/L), a specific inhibitor of PKC, and APDC, an inhibitor of NF-?B, but not be inhibited by curcumin, a inhibitor of transcriptional factor AP-1. CONCLUSION: PMA enhanced the expression of CD18 via the pathway of PKC. Transcriptional factor NF-?B, but not AP-1, was essential for the gene transcription of CD18 in U937 cells treated by PMA.

Objective To investigate skin manifestations and comorbidities of chronic arsenicosis due to conta?minated drinking water, and to explore their possible risk factors. Methods Data about demographic characteristics, skin manifestations and comorbidities were collected from 95 patients with chronic arsenicosis due to contaminated drinking water in Inner Mongolia, and retrospectively analyzed. A logistic regression model was established to analyze associations of skin manifestations and comorbidities with patients′ gender, age, age at onset of drinking of arsenic?contaminated water, arsenic concentrations in water and duration of arsenic exposure. Results Among the 95 patients, 77 had hyperpigmentation, 75 hypopigmentation, 93 palmoplantar keratoderma, 27 skin cancer, and 8 multiple skin cancer. Five patients were complicated by tuberculosis, 15 by hypertension, 2 by rheumatoid arthritis, 4 by cerebral infarction, 7 by coronary heart diseases, 3 by internal malignancy, 6 by hepatic cirrhosis and 2 by anemia. Logistic regression analysis revealed a significant correlation between hyperpigmentation and arsenic concentrations in water(OR=0.32, 95%CI=0.10-0.98;ORadjusted=0.27, 95%CI=0.08-0.90), between occurrence of hepatic cirrhosis and arsenic concentrations in water (OR=24.67, 95%CI=2.69-226.57;ORadjusted=22.51, 95%CI=2.38-213.11), and between occurrence of coronary heart diseases and duration of arsenic exposure(OR=6.41, 95%CI=1.09-37.88;ORadjusted=8.55, 95%CI=1.21-60.41). Conclusions There is a high incidence of aberrant pigment metabolism, palmoplantar keratoderma and skin cancer in patients with chronic arsenicosis due to contaminated drinking water. Different arsenic concentrations in water and duration of arsenic exposure seem to have different influences on the human body.

Sleep disorders are commonly occurred among patients with Parkinson's disease,such as difficulties in the initiation of sleep,fragmented sleep,sleep behavior disorder and excessive daytime sleepiness.The mechanism of sleep disorders associated with Parkinson's disease is not clear,which may be associated with the injury of brain stem,nuclei of median raphe,nuclei fasciculi solitarii,thalamencephalon and the changes of neurotransmitters as dopamine,hypocretin(orexin) and melatonin.This article gives an overview of the mechanism of sleep disorders associated with Parkinson's disease.

Objective:To observe the clinical effect of mind-refreshing and orifice-opening needling method plus swallowing disorder therapeutic apparatus for deglutition disorder of stroke patients in convalescence stage.Methods:A total of 136 patients conforming to the inclusion criteria were randomized into three groups by the random number table,including group A of 46 cases,group B of 44 cases and group C of 46 cases.Patients in group A received swallowing disorder therapeutic apparatus treatment,patients in group B received mind-refreshing and orifice-opening needling method treatment,and patients in group C received mind-refreshing and orifice-opening needling method plus swallowing disorder therapeutic apparatus treatment.The treatment was given once a day for 10 d as a course,the whole treatment lasted for 4 courses.Therapeutic evaluation items including water-swallowing test (WST),standardized swallowing assessment (SSA) and modified Barthel index (MBI) were measured before treatment,after treatment and at follow-up visit (2 months after treatment).Results:After treatment,scores of WST and MBI in all three groups increased significantly (all P＜0.05),while the SSA score dropped significantly (all P＜0.05).After treatment and during follow-up visit period,score of WST in group C was significantly higher than that in group A and group B (both P＜0.05),while the difference between group A and group B showed no statistical significance (P＞0.05);the SSA score in group C was substantially lower than that in group A and group B (all P＜0.05),the difference between group A and group B showed no statistical significance (P＞0.05);the MBI scores in group B and group C were substantially higher than that in group A (all P＜0.05),the difference between group B and group C showed no statistical significance (P＞0.05).After treatment and during follow-up visit period,the differences in overall therapeutic effect between group A and group B showed no statistical significance (P＞0.05),while the overall therapeutic effect in group C was substantially better than that in group A and group B (all P＜0.05).Conclusion:Both mind-refreshing and orifice-opening needling method and swallowing disorder therapeutic apparatus can alleviate symptoms of deglutition disorder of stroke patients respectively,and the combination of two methods can improve the therapeutic effect.
