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.

Objective:To study the reasons and preventive measure of the effect of human urinary kallikrein on blood pressure in the treatment of acute cerebral infarction.Method:Documents about the effect of human urinary kallikrein on blood pressure of pre-clinical study and the phaseⅠ-Ⅲclinical trials were collected and analyzed in combination with the related information of the phaseⅣclinical trial from our hospital.Result:The rate and concentration of medication in combination with ACEI were the reasons for the effect of human urinary kallikrein on blood pressure.Conclusion:Controlling the rate and concentration of medication and forbidding the combined use of ACEI from the 72hr before the medication and the 24hr after it can prevent hypotension caused by human urinary kallikrein.

AIM: To study the chloride channel activity [ICl_(Ca)] in vascular smooth cells of the spontaneously hypertensive rats (SHR). METHODS: The vascular beds of mesenteric arteries were isolated from the pentobarbital anesthetized rats and perfused with 37 ℃ PSS at a constant flow rate. The vasoconstriction response to norepinphrine (NE) was determined by changes in perfused pressure. The strips of the rat arteries were mounted in an organ chamber filled with 37 ℃ PSS and the vascular tension was measured. RESULTS: (1) The contractile responses of mesenteric arteries to NE in SHR were greater than that in Wistar rats. (2) The inhibitory magnitude of the contractile response by niflumic acid in SHR was significantly less than that in Wistar rats and showed dose-dependent manner. (3) Decreasing the extracellular Cl~- concentration increased the contractile response to NE significantly and the amplitude of enhanced contractile response in SHR was greater than that in Wistar rats. CONCLUSION: It can be concluded that NE-induced contraction is enhanced in SHR, which is partly due to an increase in Cl~- efflux through the Ca~(2+)-activated Cl~- channels. The chloride channel activity may increase in association with the elevation of vascular tone and blood pressure.

Background Retinopathy of prematurity (ROP) is one of major causes of childhood blindness.Early screening and treatment of ROP is necessary.Objective This study was to analyze the incidence of ROP in single and multiple premature infants and related factors.Methods This study was approved by Ethic Committee of Suzhou Municipal Hospital,and oral informed consent was obtained from the parents of the infants before any medical examinations.Five hundred and four fetus with the gestational age of ≤34 weeks or birth weight of ≤ 2 000 g were collected in Suzhou Municipal Hospital,of whom 357 infants were single fetus birth and 147 infants were multiple fetus,including 26 twins and 21 three fetus birth.The fundus were examined by RetCam Ⅱ equipment and ROP was determined based on the fundus findings and history of birth.ROP incidences between the single fetus and multiple fetus were compared,and the inducing factors were analyzed.Results Sixty-six infants were ROP in all 504 fetus,with the incidence of 13.10％.The incidence of ROP in the single fetal group was 10.92％ (39/357),which was significantly higher than 18.37％ (27/147) in the multifetal group (x2=5.069,P=0.024),and risk of ROP in the multifetal group was higher than that in the single fetal group (OR =1.835).The oxygen inhalation rate was 42.02％ (150/357) and the oxygen inhalation duration was 5.71 days in the single fetal group,and that in the multifetal group was 58.50％ (86/147) and 9.42 days,respectively.Conclusions Incidence and risk of ROP in the multifetal infants are higher than those in the single fetal infants,and low-birth-weight,less gestational weeks and excess oxygen inhalation are influence factors.

Objective To study the sedation and amnesia of midazolam in patients with different ages of lumbar epidural anesthesia . Methods From January to July 2015, 235 patients in the first affiliated of xian jiaotong unniversity,who were implemented abdominal surgery under combined spinal epidural anesthesia and American Society of anesthesiologists (ASA) grade was I-II , were divided into three groups:young group (n=70); middle-aged group (n =82); elderly group (n =83).Intraoperative continuous monitoring of respiratory and circulatory function index,and recorded MAP,SpO2, HR before and 5, 15, 30 min after injection.ResuIts MAP, HR and SpO2 of three groups were compared with the same time points pre-and post used of midazolam, there was no significant difference among indicators.; Compared with the same group at different time points, MAP(FYG =9.2547,FMG =12.8181,FOG =17.77)和 SpO2 (FYG =190.3835,FMG =196.2393,FOG =270.5609),there were significant difference.The difference was not statistically significant between HR group and the same group at different time points and forgetting degree and sedation score , but compared with OG,there were significant difference(P<0.05).The total number of adverse reactions in YG group and MG group was less than that of OG group(X2 =11.2516,X2 =10.4491, P<0.05).ConcIusion The effect of the same dose of midazolam on sedation and amnesia in patients with different ages of lumbar epidural anesthesia is different, and the degree of the effect of the elderly patients is significant,but will produce more adverse reactions.Therefore, in the combined spinal epidural anesthesia,it is necessary to consider the patient's individual differences, rational use of sedative and narcotic drugs.

Post-stroke fatigue (PoSF) is an independent pathologic symptom after stroke which negatively influenced activities of daily living (ADL) and quality of life (QOL) of the stroke patients. PoSF is irrelevant to depression, age, state of the illness, etc. PoSF should be assessed appropriately and alleviated by medicine, diet, sleep, exercise, and health education, etc.

ObjectiveTo observe the projections from respiratory neurons of medulla oblongata to the motor neuron pool of phrenic nerve in rat. MethodsBy using horseradish peroxidase (HRP) retrograde tracing technique after injecting HRP into phrenic nerve, retrograde labelled neurons were found in C3-C5 segment. Then, HRP was injected into the area where the phrenic motor neurons occupied, retrograde labelled neurons were found in medulla oblongata. ResultsPhrenic motor neurons locate in the C3-C5 segment ipsilaterally, occuping the intermediate portion of anterior horn and appearing typical motor neurons. Retrograde labelled neurons were found bilaterally in medulla oblongata, the neurons were located in nucleus retroambigualis (RNA), ventramedial area to nucleus retrofacialis (NRF). ConclusionThe phrenic motor neurons may receive direct projection of respiratory neuron in medulla oblongata, the projecting neurons are distributed in RNA and NRF area.

Genetic mutations are important molecular biomarkers for cancer diagnosis and surveillance.Therefore,the development of methods for mutation detection characterized with straightforward,highly specific and sensitive to low-level mutations within various sequence contexts is extremely needed.Although some of the currently available methods have shown very encouraging results,their discrimination efficiency is still very low.Herein,we demonstrate a fluorescent probe coupled with blocker and property of melting temperature discrimination,which is able to identify the presence of known or unknown single-base variations at abundances down to 0.1％ within 20 min.The discrimination factors between the perfect-match target and single-base mismatched target are determined to be 10.15-38.48.The method is sequence independent,which assures a wide range of application.The new method would be an ideal choice for high-throughput in vitro diagnosis and precise clinical treatment.

Objective To compare the clinical effect of total laparoscopic and open liver resection for tumors in segments Ⅶ and Ⅷ.Methods The clinical data of patients with tumors in segments Ⅶ and Ⅷ of the liver who met the inclusion criteria and received operation at Affiliated Hospital of Nantong University from January 2011 to January 2015 were retrospectively analyzed.Among these patients, there were 17 cases who received total laparoscopic liver resection (LLR group), and 25 cases who received open liver resection (OLR group).Results LLR group has obvious advantages in aspects of the level of serum alanine transaminase (ALT) on 1st and 3rd day postoperation, the time anal exsufflation, the drainage volume of abdominal cavity in 3 days after operation and the postoperative hospital stay than those in OLR group (respectively t =-3.075,-3.175,-2.499,-2.088,-2.419, all P ＜ 0.05).There were no significant differences in blood transfusion rate, the resection margin to the tumor, the postoperative morbidity and the total medical cost between the two groups (x2 =1.437, t =-1.244, x2 =0.209, t =1.079, all P ＞ 0.05).Though the mean operative time and intraoperative blood loss of LLR group compared with OLR group increased obviously (respectively t =3.360, 2.189, all P ＜ 0.05).During the postoperative follow-up, there were no significant differences in the postoperative recurrence rate and the long-term survival rate in patients with malignant tumors (respectively x2 =0.240, 0.000, all P ＞ 0.05).Conclusion The therapeutic effect of total laparoscopic and open liver resection are equal in segments Ⅷ and Ⅷ hepatectomy, while, LLR has advantages of less trauma.
