Objective To investigate the serum lipoprotein (Lp) (a) level in patients with acute ischemic stroke and the prediction for short-term functional outcome. Methods The levels of serum Lp(a) were measured in 210 patients with acute ischemic stroke (within 24 h after onset) and 100 healthy people matched the gender and age. The patients were assessed with National Institutes of Health Stroke Scale (NIHSS) as admission, and modified Rankin Scale (mRS) as discharge. Results The median of Lp(a) was 325 mg/L (IQR: 180~545) in patients,significantly more than 148 mg/L (IQR: 69~265) in the normal controls (P<0.001). Level of serum Lp(a) was an independent variable for functional outcome (OR=1.004, 95%CI: 1.001~1.007, P<0.001) and death (OR=1.006, 95%CI: 1.001~1.008, P<0.001) in patients. In the receiver operating characteristic curve, the area under curve was more in the combined model [Lp(a) and NIHSS] than the NIHSS alone.Conclusion Serum Lp(a) increased in the in patients with acute ischemic stroke, and may predict the short-term outcome independently.

Objective To investigate the improving effects of Shenshao decoction on myocardial structure and function in diabetic cardiomyopathy,and its effect on expression of TLR4/MyD88-dependent pathway signal in diabetic cardiomyopathy.Methods Diabetes mellitus was induced in 8-week-old male Wistar rats by a single intraperitoneal injection of streptozotocin.The changes of plasma myocardial enzyme (CK, LDH) and high sensitive C reactive protein (hsCRP) were measured.Cardiac function was measured by left ventricular intubation.Hematoxylin and eosin staining and electron microscopy were used to observe the changes of myocardial morphology and ultrastructure in rats.Expression of Toll-like receptor 4(TLR4), myeloid differentiation protein 88(MyD88), and nuclear factor-κB P65(NF-κB P65) were tested by immunohistochemistry.Results After 6 weeks of treatment, the left ventricular diastolic and systolic functions were obviously improved;the degrees of myocardial fibers and mitochondrial damage were obviously relieved;the content of CK, LDH and hsCRP decreased (P< 0.05), and hsCPR was positively correlated with CK and LDH (r=0.823,r=0.819,P < 0.05).The expressions of TLR4, MyD88, NF-κB P65 were significantly decreased (P< 0.05).There was no significant difference in the above mentioned indicators between the control group and control+Shenshao decoction group (P> 0.05).Conclusions Shenshao decoction can reduce the myocardial injury in diabetic cardiomyopathy and improve cardiac diastolic and systolic functions.The mechanism may be related to attenuated inflammation by TLR4/MyD88 dependent signaling pathway.

Objective To evaluate the effects of nursing intervention on the beliefs and behavior of early detection of breast cancer. Methods Four communities in Shanghai were selected by convenient sampling process. Then these four communities were randomly assigned to intervention group and control group. One hundred and eighty women who met the criteria of this study were selected from each group by convenient sampling process.Altogether 739 women were recruited. In intervention group,a one-year nursing intervention guided by health belief model was implemented,such as health education seminars,telephone follow in the third,sixth,and ninth months,and flyers of breast health care in the sixth month. Control group only received conventional education. Results After intervention women became aware of breast cancer (B=0.210,P＜0.01),perceived more benefits from attending early breast cancer detection (B=0.105,P＜0.01),and less difficulties in attending the activities of early detection of breast cancer (B=-0.086,P＜0.05). The number of women who performed breast self-examination once per month increased and more women received clinical breast examination (OR=3.0946) and mammogram after intervention (OR=2.746). Conclusion The nursing intervention,guided by health belief model,is helpful to improve women's beliefs and behaviors of breast cancer detection.

Objective:To investigate the clinical efficacy of mechanical solitaire AB stents thrombectomy combined with intra-arterial thrombolysis in the treatment of patient with acute ischemic stroke.Methods:Fifteen patients with acute ischemic stroke admitted into our hospital from August 2014 to August 2016 were treated with mechanical thrombectomy with solitaire AB stents plus intra-arterial thrombolysis.The National Institutes of Health Stroke Scale score (NIHSS) of all patients were evaluated before and after treatment to compare the clinical efficacy.The prognosis ofpatients between two groups were compared via evaluating modified Rankin score (mRS)and gelasijia coma score (GCS).Results:After mechanical thrombectomy with solitaire AB stents plus intra-arterial thrombolysis treatment,14 patients achieved complete or part recanalization,and 1 patient was terminated treatment due to vital signs instability,and the rate ofrecanalization was 93.3％.The NIHSS score of patients before treatment was 12.93± 4.25,which was much higher than that after treatment (4.33± 1.45,P＜0.05).After follow-up by 3 months,the good mRS scores were obtained in all 18 patients,including 2 patients with mRS score of 2,5 patients with 1,and 8 patients with 0.Additionally,there was no patient with re-obstruction during follow-up period.Conclusion:Mechanical thrombectomy with solitaire AB stents combined with intra-arterial thrombolysis had a good capability and safety in the treatment of patients with acute ischemic stroke.

Mink plasmacytosis, caused by Aleutian Mink Disease Virus (AMDV), poses a threat to the development of the animal fur industry. Neutralizing antibodies against AMDV may result in a persistent infection rather than providing protection for minks. To date,no specific methods to prevent or cure this disease have been developed. In order to eliminate mink plasmacytosis, antibody detection technology has been used globally as a dominant approach to screen for AMDV-positive minks. This paper introduces the classical technology, counterimmunoelectrophoresis and emerging technology in terms of AMDV antibody detection,and provides a glimpse into the future development of these technologies.

Objective The incidence of alcoholic fatty liver increases year by year in recent years .The aim of this study was to establish an animal model of AFL to investigate the pathogenesis of hepatic fibrosis . Methods This study involved 40 male Japa-nese rabbits aged (17.01 ±1.54) d and weighing 1.00-1.52 kg, which were equally randomized to an experimental group and a control group.The animals in the former group received lavage of 10 mL of 50%ethanol twice a day, with normal feedstuff and water, while those in the control group received normal feedstuff and water only .We performed ultrasonography for dynamic liver presentation before and at 12, 16, and 20 weeks after feeding, followed by pathological observation of the livers . Results After 12 weeks of eth-anol garage , fatty liver was observed in 18 of the rabbits and it deteriorated with the prolonged time of administration . The body weight was significantly decreased in the experimental rabbits as com-pared with the controls at 16 weeks ([2.48 ±0.30] vs [2.78 ± 0.15] kg, P<0.05) and 20 weeks ([2.61 ±0.44] vs [3.10 ± 0.13] kg, P<0.05).Ultrasound and pathological grading showed 1 mild, 3 moderate, and 13 severe cases of fatty liver in the experimen-tal group, but none in the control , and pathological examination re-
vealed similar results (1 mild, 4 moderate, and 12 severe cases of fatty liver) in the former group.At 20 weeks, alcoholic fatty liver was found mainly in the S3-S4 stage. Conclusion Alcoholic fatty liver models could be successfully established in rabbits by etha-nol garage and ultrasonography is useful for monitoring the development and progression of the condition .

Objective Folate receptors ( FRs) , overexpressed on the surface of a variety of tumor cells , are potential targets for tumor targeting therapy .This study aimed to prepare an FR-mediated drug nanocarrier with folate conjugated pullulan acetate ( FPA) to target chemotherapeutic agents to FR-overexpressed tumor cells and investigate its tumor-suppressing effect in vitro. Methods The cytotoxicity of epirubicin-loaded FPA nanoparticles ( FPA/EPI NP) against HepG2 and Hela cells was evaluated by MTS assay.The HepG2 and Hela cells were divided into five groups to be treated with NPs (NP control), chlorpromazine, chloro-quine, amiloride, and folate, respectively, followed by detection of the fluorescence intensity by flow cytometry . Results FPA/EPI NP was successfully formulated into NPs , with the mean particle size of (268.5 ±12.0) nm, by dialysis with an almost spherical shape . The drug-loading rate and entrapment rate of FPA/EPI NP were (6.45 ±1.04) and (72.45 ±11.50) %, respectively.The survival rates of the HepG2 and Hela cells were both >95%after 24 hours of incubation with FPA NP at 5, 40, 200, 400 and 1000μg/mL and 90.0%after 72 hours.The survival rates of the HepG2 cells treated with 5, 40, 200, 400 and 1000μg/mL FPA/EPI NP for 24 hours were (92.3 ±5.2), (70.4 ±4.6), (50.0 ±4.0), (41.1 ±4.1) and (27.0 ±3.6) %, respectively.Compared with the NP control group, the Hela cells of the chlorpromazine , amiloride and folate groups showed a significantly lower rate of NP uptake (P<0.05), and so did the HepG2 cells pretreated with chlorpromazine or amilo-ride (P<0.05).At 72 hours, the half maximal inhibitory concentrations (IC50) of FPA/EPI NP against HepG2 and Hela cells were 168 and 105μg/mL, respectively . Conclusion Clathrin-mediated endocytosis and macropinocytosis are involved in the internaliza-tion of FPA/EPI NP in HepG2 cells, while clathrin-and FR-mediated endocytosis in that of Hela cells .FPA NP may serve as a new drug carrier for tumor-targeted therapy .

Objective To observe the effect of hypothermia in reperfusion stage on prognosis during adult liver transplantation.Methods Data of 107 patients (62 males, 45 females, aged 25～65 years, ASA physical status Ⅲ or Ⅳ) underwent adult liver transplantation from January 2015 to December 2016 in our hospital were retrospectively analyzed.The temperature at the time of anesthesia induction (T0), skin incision (T1), anhepatic phase immediately (T2), immediate reperfusion (T3), 5 min after reperfusion (T4), abdomen-closing (T5) and the end of surgery (T6) were recorded to observe the trend of overall temperature change.Patients were devided into normal temperature group (core temperature was≥35℃ or ＜35℃ but the duration was less than 5 min in reperfusion period) and hypothemia group (core body temperature was ＜35℃ and the duration was>5 min) to compare difference between the two groups of perioperative blood loss, urine volume, postoperative extubation time, ICU staying time and hospitalization time.The influence of hypothermia during the new liver phase (T4-T6) on prognosis and correlation between duration of hypothermia and blood loss, urine volume, postoperative extubation time, ICU staying time and hospitalization time were analyzed.Results This study found that during the perioperative adult liver transplantation, the body temperature showed a decreasing trend first (T0-T4) and then an increasing one (T4-T6).The body temperature droped to the lowest at T4, which was lower than the normal body temperarure.Compared with T0, the temperature decreased obviously at T2-T5 (P＜0.05);Compared to normal temperature group, the amount of bleeding was more and the extubation time was longer in hypothermia group (P＜0.05), and there was no significant difference in urine volume, ICU staying time and hospitalization time between the two groups.There were positive correlations between the time of hypothermia and bleeding, extubation time, ICU staying time and negative correlations with urine output, while no obvious relations with postoperative hospital staying time.Conclusion During the perioperative liver transplantation, hypothermia increased the blood loss and postoperative extubation time.The longer the hypothermia time is, the poorer the prognosis is.
