Chinese Journal of Anesthesiology 2014;34(11):1396-1398
Objective To evaluate the effects of postconditioning with ischema and propofol on retinal injury induced by limb ischemia-reperfusion (LIR) in rats.Methods Twenty-four male Wistar rats were randomly divided into 3 groups (n =8 each) using a random number table:sham operation group (group S),group LIR,and propofol postconditioning + postconditioning + ischemic LIR group (group P + I + LIR).The model of LIR was established by separating and ligating the femoral artery and vein of bilateral hind limbs for 60 min followed by reperfusion.In group P + I + LIR,the animals were subjected to 4 episodes of 60 min ischemia-5 min reperfusion-5 min ischemia-5 min reperfusion and to 4 cycles of propofol 500 μg· kg-1 · min-1 infused intraperitoneally at the same time (during reperfusion)-no propofol infusion during second ischemia.At 120 min of reperfusion,blood samples were collected from the abdominal aorta for determination of serum malondialdehyde (MDA) concentrations.The eyeball was removed and the retina was cut into sections which were stained with H.E.and examined by microscopy.Results Compared with group S,the serum MDA concentration was significantly increased in group LIR,and no significant change was found in the serum MDA concentration in group P + I + LIR.The serum MDA concentration was significantly lower in group P + I + LIR than in group LIR.The structure of retina was normal in group S,oedema was found in all the layers of retina,vacuolar degeneration was observed in the most of ganglionic layers,and the structure disturbance was found in group LIR.The pathological changes of retina were significantly attenuated in group P + Ⅰ + LIR.Conclusion Postconditioning with ischema and propofol can attenuate retinal injury induced by LIR,and the mechanism is related to inhibition of lipid peroxidation in rats.

Chinese Journal of Primary Medicine and Pharmacy 2015;22(4):527-531
Objective This research was designed to reveal the influence of the new rural cooperative medical system (NRCMS) on anticoagulant therapy of warfarin in atrial fibrillation (AF) patients in Gaochun district,Nanjing city.The reasons of not attending NRCMS and the relationship between NRCMS and the reasons of not correctly anticoagulant therapy were also investigated.Methods We collected outpatients and inpatients in Gaochun district in our hospital who suffered with AF and did not attend any medical insurance except NRCMS.Patients' data of whether enrolled in NRCMS,whether anticoagulated with warfarin,whether measure international normalized ratio and then confine it in therapeutic extent and fundamental data of gender,age etc.were collected by questionnaire.Then,the data were analyzed.Results A total of 1 094 patients were included in our research of which 896(81.9%) patients were enrolled in NRCMS.198 subjects did not attend NRCMS.The most common reason was not getting the message of NRCMS,which covered 104 patients (52.5%).Among the patients without counter indications of warfarin,801 patients did not be anticoagulated,of which 637 were covered by NRCMS and 164 were not insured by NRCMS,which accounted for 71.1% and 82.8% of their total respectively.The difference was statistically significant (x2 =11.387,P =0.001).Similar to the nonNRCMS,the most common reason of not accepted anticoagulation in patients covered by NRCMS was taking substitutions,which was hold by 42.9% patients.All the differences of proportions of patients had recorded reasons with and without NRCMS had no statistical significance except for the proportion of patients who hold the reason of not knowing the necessity of anticoagulation,having difficulty in daily life,and compound reasons.Among the anticoagulated patients,202 cases did not restrict INR in therapeutic range,of which 170 cases were covered by NRCMS and 32 cases were not insured by NRCMS,which accounted for 65.6% and 94.1% of their total respectively.The difference was statistically significant (x2 =11.385,P =0.001).The most common reason of not restricting INR in patients covered by NRCMS was did not know the necessity of restricting INR,which was hold by 40.6% patients.The proportions of patients who did not take anticoagulation with the reason of having difficulty in daily life had statistical difference,while the difference of other reasons did not meet statistical significance.Conclusion There were many patients did not attended NRCMS.NRCMS can improve the proportion of anticoagnlation therapy with or without correct ways.However,there were many patients did not treated with anticoagulation and there were many patients did not restrict INR in therapeutic rainge.Propaganda,health education and directions of health information are needed.
3.Research advances in the pathogenesis of multiple organ dysfunction syndrome in patients with liver cirrhosis and related treatment regimens
Journal of Clinical Hepatology 2017;33(6):1165-1168
Recent studies have shown that complications of cirrhotic portal hypertension often involve multiple organs,which is called multiple organ dysfunction syndrome by some scholars.When muhiple organ failure occurs,there is a significant increase in patients'short-term death rate,and death rate is associated with the number of organs involved.This article briefly describes the physiopothologic mechanisms of portal hypertension and visceral vasodilation and summarizes the pathological changes of vital organs including the heart,lung,kidney,brain,and liver and related pathogenesis.At present,liver transplantation remains the most effective therapy,but it still has some shortcomings.It is pointed out that further studies are needed to investigate the mechanisms of action of each link in disease development,and more targets are needed in the future to prevent and treat multiple organ dysfunction syndrome in patients with liver cirrhosis.
4.Progress in Non-invasive Diagnosis and Assessment of Non-alcoholic Fatty Liver Disease
Chinese Journal of Gastroenterology 2017;22(9):561-564
Non-alcoholic fatty liver disease (NAFLD)is a clinical syndrome characterized by hepatic fat deposition, and not caused by chronic heavy drinking and other liver damage factors. The pathogenesis of NAFLD is associated with environmental,genetic,immune and other various factors. Early diagnosis is helpful not only for distinguishing between simple non-alcoholic fatty liver (NAFL)and non-alcoholic steatohepatitis (NASH),but also for grading the extent of NAFLD lesion and delaying its further development. This article reviewed the clinical research progress of non-invasive diagnosis and evaluation of NAFLD.

Objective To investigate clinical effect of sIgA combined with Jiawei Yuping Feng pulvis in treatment of upper respiratory infection ( URI) in children.Methods 160 children in hospital diagnosed with URI were randomly divided into treatment group and control group.With basic treatment, the control group were treated with Jiawei Yuping Feng pulvis, twice per day, 3 g each time, orally; treatment group on the basis of control group, secretory IgA via nasal drip, 0.3-0.5 mg/( kg? d) , dividing into 6-8 times.The treatment course was 7 days.The total efficiency, improvement of symptoms and adverse reactions were observed and compared.Results The total effective rate of treatment group (96.25%) was significantly higher than control group (85%)(χ2 =5.96, P<0.05).After 7 days of treatment, WBC and NEUT% of treatment group decreased significantly compared with control group ( P <0.05 ) .The fever, sore throat and runny nose, cough and expectoration symptom remission time of treatment group were significantly shorter than control group (P<0.05).Adverse reactions of both groups were lower.Conclusion It is effective to treat URI in children using sIgA combined with Jiawei Yuping Feng pulvis therapy, and it has few adverse reactions.
8.The effect of ischemia-reperfusion injury on concentrations of free amino acids in rat myocardium and taurine's protective role
Chinese Pharmacological Bulletin 1987;0(02):-
By using the model of ischemia-reperfusion injury in the isolated working rat heart,the change of free amino acid concentrations in myocardium and the effect of taurine on the heart were investegated. It was found that concentrations of 17 free amino acids in myocardium, except Cys,decreased,and that 20mM taurine was able to ameliorate the ischemia-reperfusion injury of the heart ;e. g. , the improvement of recovery of cardiac mechanical functions, the decrease in the leakage of LDHand CK from myocardium,in the accumulation of lipid peroxides and calcium,and in the loss of free amino acids in myocardium,as well as the decrease in the occurence rate of ventricular arrhythmias during the reperfusion phase. So, it may be suggested that exogenous taurine has some protective effects against the myocardial is-chemia-reperfuaion injury.
