Objective To observe the long-term effect of combined intestine/auxiliary liver transplantation in rat.Methods Male Lewis rats were used. Total small bowel and 60 % liver were transplanted en bloc with an aortic segment that contained the celiac axis and superior mesenteric artery ensuring the blood supply to the graft. The end-to-side anastomosis was made between donor infrahepatic vena cava (IHVC) and recipient IHVC. The recipient small bowel was resected and the intestine continuity was restored. Sham control (laporotomy only) and transplantation groups were included. Ten rats in each group were followed-up for 18 months and then sacrificed. Liver function tests, terminal deoxynuleotidyl transferase-mediated 2'-deoxyuridine 5'-triphosphate (dUTP) nick end labeling (TUNEL) staining and proliferating cell nuclear antigen (PCNA) staining of liver tissue were evaluated.Results Sixteen rats survived over the operation. There were no significant differences in liver function tests between the sham control group and transplantation group. The grafted liver was hypertrophic and native liver did not regenerate 18 months following transplantation with an increased liver/body weight ratio. TUNEL-staining showed no significant differences among grafted liver, native liver of the recipient rat in transplantation group and the liver of the rat in control group. PCNA-staining revealed that the native liver in transplantation group had a lower proportion of TUNEL-positive hepatocytes. Conclusion This experimental study confirmed the long-term consequences of combined intestine-auxiliary liver transplantation, and the results suggest that liver/body weight ratio can be increased.
2.Advances in clinical studies of cardiopulmonary resuscitation
World Journal of Emergency Medicine 2015;6(2):85-93
BACKGROUND: The survival rate of patients after cardiac arrest (CA) remains lower since 2010 International Consensus on Cardiopulmonary Resuscitation (CPR) and Emergency Cardiovascular Care (ECC) was published. In clinical trials, the methods and techniques for CPR have been overly described. This article gives an overview of the progress in methods and techniques for CPR in the past years. DATA SOURCES: Original articles about cardiac arrest and CPR from MEDLINE (PubMed) and relevant journals were searched, and most of them were clinical randomized controlled trials (RCTs). RESULTS: Forty-two articles on methods and techniques of CPR were reviewed, including chest compression and conventional CPR, chest compression depth and speed, defibrillation strategies and priority, mechanical and manual chest compression, advanced airway management, impedance threshold device (ITD) and active compression-decompression (ACD) CPR, epinephrine use, and therapeutic hypothermia. The results of studies and related issues described in the international guidelines had been testified. CONCLUSIONS: Although large multicenter studies on CPR are still difficult to carry out, progress has been made in the past 4 years in the methods and techniques of CPR. The results of this review provide evidences for updating the 2015 international guidelines.

Objective:To survey the enablement level of elderly patients in the community and its influencing factors.Methods:A total of 460 patients aged ≥60 years visiting Changfeng and Fenglin Community Health Service Centers of Shanghai during September 3 to 15, 2018 were invited for a questionnaire survey. A self-made health status questionnaire, Patient Enablement Instrument (PEI), Chinese Health Questionnaire (CHQ-12), the Consultation and Relational Empathy Measure (CARE) were applied for survey.Results:All valid 460 questionnaires were retrieved. The positive rate of patient enablement was 73.91% (340/460). The median score for PEI was 3, Q1 was 0 and Q3 was 6. The univariate analysis showed that patient′s gender( Z=-2.32, P=0.02), age ( H=9.73, P<0.01), reason for visit ( H=42.06, P<0.01), health status in the past year ( H=8.28, P=0.02), consultation time ( H=22.92, P<0.01), sufficiency of communication with the doctor as patient thought ( H=41.83, P<0.01), detailed inquisition ( H=81.11, P<0.01), attending a contracted doctor ( Z=-3.42, P=0.04), the satisfaction of the visit ( H=38.64, P<0.01), total score of CHQ-12 ( Z=-2.01, P=0.04) and the score of CARE were significantly associated with the enablement level of the patient after the visit ( H=288.06, P<0.01). Multivariate linear regression showed that age 60-79( P=0.03), visit for acute disease( P<0.01), good or moderate health status in past year ( P<0.01), communication with the doctor<3 min or 3-<5 min ( P<0.01), sufficient or moderate time for communication with the doctor as patient thought ( P<0.01), detailed or moderate inquisition( P=0.03 or P=0.01), attending a contracted doctor ( P<0.01), CHQ-12 ≥4 ( P<0.01), middle or high CARE score ( P<0.01)were associated with the enablement of elderly patients after visit, with a cumulative contribution rate of 73.40%( F=50.08, P<0.01). Conclusion:The level of enablement of elderly patients after visiting the general outpatient clinic of the community health service center is relatively low. Patient′s age, types of disease, health status and the time of communication with the doctor, the sufficiency of communication time as patient thought, the detailed inquisition, attending a contracted doctor, the mental health status, and the empathy expression of the doctor are associated with the enablement of patients.

OBJECTIVE:To observe clinical efficacy and ADR of Houttuynia cordata eye drops combined with Olopatadine eye drops in the treatment of allergic conjunctivitis. METHODS:160 eyes with allergic conjunctivitis were randomly divided into observation group and control group,with 80 eyes in each group. The control group was given olopatadine eye drops,and observa-tion group was additionally given H. cordata eye drops(medication interval>10 min)on the basis of control group. Both groups were treated for 14 days. Symptoms and signs of 2 groups were observed and scored before treatment and 14 d after treatment. Ef-fective rates of 2 groups were calculated,and the occurrance of ADR was observed. RESULTS:Compared with before treatment, symptoms and sings score of 2 groups were decreased,with statistical significance (P<0.01 or P<0.05);the decrease of two score in observation group were more significant than in control group,with statistical significance (P<0.05);effective rates of control group and observation group were 37.50%and 77.50%,with statistical significance(P<0.05). CONCLUSIONS:H. corda-ta eye drops combined with olopatadine eye drops can ameliorate clinical symptoms and signs of allergic conjunctivitis patients sig-nificantly,and improve therapeutic efficacies without obvious ADR.

The impeller profile, which is one of the most important factors, determines the creation of shear stress which leads to blood hemolysis in the internal flow of centrifugal blood pump. The investigation of the internal flow field in centrifugal blood pump and the estimation of the hemolysis within different impeller profiles will provide information to improve the performance of centrifugal blood pump. The SST kappa-omega with low Reynolds correction was used in our laboratory to study the internal flow fields for four kinds of impellers of centrifugal blood pump. The flow fields included distributions of pressure field, velocity field and shear stress field. In addition, a fast numerical hemolysis approximation was adopted to calculate the normalized index of hemolysis (NIH). The results indicated that the pressure field distribution in all kinds of blood pump were reasonable, but for the log spiral impeller pump, the vortex and backflow were much lower than those of the other pumps, and the high shear stress zone was just about 0.004%, and the NIH was 0.0089.
