Objective To explore the effects of Levoeitirize dihydrochloride on interleukin-13(IL-13)and interleukin-18(IL-18)in the serum of the patients with cough variant asthma(CVA).Methods 70 cases with CVA were randomly devided into control group of 35 cases and treatment group of 35 cases.Control group was given Chlort rimeton and the treatment group was given Levocitirize dihydroehloride.The levels of IL-13 and IL-18 in the serum were measured before and after treatment.Results After treatment,the concentrations of IL-13 and IL-18 in patients in the treatment group were(46.7±17.3)ng/L and(145.2±27.1)ng/L，and those in the control group were(98.5±30.7)ng/L and(179.6±30.5)ne/L，which were significantly improved.Conclusion The treatmem of Levoeitirize dihydrochloride could improve the CVA through improving the production of IL-13 and IL-18.

Objective To prospectively evaluate the risk factors of complete resection in early gastric cancer (EGC) with endoscopic submucosal dissection (ESD),and to guide the choice of treatment methods.Methods This study prospectively evaluated the endoscopic features of 66 EGCs,including the lesion size,presence or absence of ulceration,the extent of differentiation,invasion depth and entire margins of the EGC,then compared them with postoperative pathologic results and analysed these factors.Results The lesion size of the high grade intmepithelial neoplasia (H) group and the intramucosal carcinoma (M) group were mainly less than 30 mm (90.9％ vs.88.5％),but 57.1％ of the submucosal carcinoma (SM) were more than 30 mm.There was a significant difference between any two of three groups (P ＜ 0.05).Fourteen EGCs who got ulceration without invasion beyond mucosal muscularis underwent ESD successfully,and the basal or dissected margin had no residual tumor cells confirmed pathologically.And no tumor cell infiltration or lymph node metastasis was discovered.Of 45 EGCs with ESD,the underestimation rate for horizontal extent determined by white light and chromoendoscopy was higher than that of magnifying endoscopy with narrow-band imaging (ME-NBI) (15.6％ vs.2.2％,P ＜0.05).Diagnostic accuracy for the extent of differenciation by conventional endoscopy was 93.9％ (31/32,P ＞ 0.1),but it's unable to determine the extent of differentiation by ME-NBI.The accuracy of the group H was 84.8％ (28/33),that of M was 57.7％ (15/26),that of SM was 71.4％ (5/7),and there was a significant difference between group H and group M (P ＜ 0.05).Conclusion To achieve complete resection of EGC with ESD,the lesion more than 30 mm,presence of ulceration,undifferentiated type,deep infiltration should be considered as the risk factors,and it's also important to identify the horizontal extent of EGC to avoid unnecessary operation.

Objective To evaluate the long-term prognosis and safety of ABO-incompatible (ABO-I) liver transplantation on type-O patients with acute severe liver disease,analyze and compare the effects and main complications between different donor blood types,and investigate corresponding treatment measures.Methods The clinical data of 65 cases of emergency orthotopic liver transplantation (OLT) for type-O patients with acute severe liver disease from January 2014 to January 2017,including 41 cases of ABO-compatible (ABO-C) OLT and 24 cases of ABO-incompatible OLT (7 with type-A donor,9 with type-B donor,and 8 with type-AB donor) were retrospective analyzed.Results The model for end-stage liver disease (MELD) score in the ABO-incompatible group was 32.5±5.5,significantly higher in the ABO-compatible group (23.3±8.9) (P=0.001).The data of the other perioperative factors showed no statistically significant difference between two groups.The cumulative survival rate in the ABO-compatible group was 87.8 % (36/41),not significantly different from that in the ABO-incompatible group [87.5% (21/24),P=0.924].The 57 cases who had survived after perioperative period were followed up for 4-37 months (mean 18 months).Significantly higher incidence of hepatic artery and biliary complications was found in ABO-incompatible group (P=0.005,and P<0.001,respectively).The incidence of hepatic artery complication and biliary complication in ABO-incompatible group was 29.2% (7/24) and 37.5% (9/24),and that in ABO-compatible group was 4.9% (2/41) and 0 (0/41),respectively.The rate of acute rejection in the ABO-incompatible group and ABO-compatible group was 9.8% (4/41) and 4.2% (1/24) (P=0.463).The infection rate in the ABO-compatible group and ABO-incompatible group was 24.3% (10/41) and 29.2%(7/24),respectively (P=0.598).Conclusion The different donor blood types including ABO-compatible and ABO-incompatible liver transplantation program on type-O patients with acute severe liver disease have a favorable outcome.The long-term cumulative survival rate between two groups shows no significant difference.With the help of effective immunosuppression and intensive perioperative management,ABO-incompatible liver transplantation is an acceptable option to cure type-O patients with acute liver failure in emergency.The incidence of hepatic artery and biliary complications was lower in ABO-compatible group than in ABO-incompatible group.For the type-O patients with ABO-incompatible liver transplantation,the use of rituximab and plasma exchange to decrease the antibody titers of recipients is essential to prevent and cure the hepatic artery and biliary complications.

ObjectiveTo explore and analyze the effect of simulation-based learning combined with debriefing in neonatal resuscitation training.MethodsA total of 114 clinical medical staffs attended the neonatal resuscitation training course hold by Department of Neonatology, Quzhou Maternal and Child Health Hospital from November 2014 to May 2015, and were randomly assigned to observation (n=60) and control group (n=84) by coin tossing. Staffs in the observation group adopted to training skills with simulation-based learning combined with debriefing,while those in the control group were educated with traditional method. The examinations on theoretical knowledge were taken before and after the training. Operational exam and self-confident questionnaire for all staffs on each procedure taught in the course were taken at last. Scores of the exams and self-confident questionnaire were compared between the two groups witht-test and Mann-WhitneyU test.ResultsThe mean score of theoretical test rose up significantly after the training in both observation and control group (25.19±2.62 vs 20.17±3.71,t=7.725,P<0.01; 25.44±2.64 vs 18.90±4.27,t=11.170,P<0.01), but no difference was found in this score after the training between the two groups (t=0.492,P=0.624). The practical operation examination score in the observation group was higher than that in the control (34.05±1.34 vs 31.32±4.10,t=4.183,P<0.01). All questionnaires sent to the staffs were retrieved (100%), and the total values after the training in the observation group were higher than in the control (mean rank: 92.81 vs 57.99; rank sum:5 569 vs 4 872,Z=-4.96,P<0.01).ConclusionsSimulation-based learning combined with debriefing is a much more effective teaching methods for neonatal resuscitation training, which might quickly improve the resuscitation skills of clinical staffs.

Objective Neuropsychiatric systemic lupus erythematosus ( SLE) is a common complication of SLE, whose path-ogenesis is not yet clear but associated with the alteration of cerebral blood flow ( CBF) in some studies.This study was to investigate the CBF alteration in SLE patients without overt neuropsychiatric symptoms by arterial spin labeling ( ASL) MRI. Methods Twenty-eight SLE patients without overt neuropsychiatric symptoms and 30 age-and sex-matched healthy controls underwent conventional MRI and ASL examinations, and all received such neuropsychologic tests as number connecting test-A ( NCT-A ) , digit symbol test ( DST ) , self-rating anxiety scale ( SAS ) , and self-rating depression scale ( SDS) .Independent sample-t test was used to detect the mean CBF in the whole brain, gray matter, and white matter of the SLE patients and healthy controls.The voxel-wise CBF maps of the two groups of subjects were further analyzed with the SPM8 software to compare the regional CBF between the two groups, followed by evaluation of the correlation between the regional CBF values and clinical markers. Results In comparison with the healthy controls, the SLE pa-tients showed significantly reduced CBF in the gray matter (40.5 ±3.7 vs 37.3 ±6.5, P=0.028) and the whole brain (38.0 ±3.5 vs 35.1 ±6.1, P=0.032), especially in the supplementary motor area and the adjacent middle cingulate, anterior cingulate, left medial frontal gyrus, left inferior frontal gyrus, and left insula (P<0.05, FWE corrected).The NCT-A score was negatively correlated with the CBF values of the left medial frontal gyrus (r=-0.402, P=0.032) and left inferior frontal gyrus (r=-0.382, P=0.045) of the SLE patients. Conclusion ASL and MRI showed significantly reduced cerebral blood flow in the SLE patient without overt neu-ropsychiatric manifestations, which was correlated with the change of the patient's cognitive function.

Objective To explore the association between the C46T polymorphism of coagulation factor Ⅻ (FⅫ) gene and the involvement of FⅫ activity (FⅫ:C) in patients with unexplained recurrent spontaneous abortion (URSA), and to elucidate its role in the pathogenesis of URSA. Methods This study included 203 patients with URSA (URSA group) and 171 healthy women with at least one child and no history of infertility or miscarriage (control group) in the southern area of Zhejiang Province. The C 46T polymorphism of the FⅫ gene was analyzed with matrix-assisted laser desorption/ionization time of flight-mass spectrometry (MALDI-TOF-MS) in all subjects. The values of prothrombin time, activated partial thromboplastin time (APTT), fibrinogen, FⅫ:C and other coagulant parameters were determined. The frequency distribution of the wild-type (CC), heterozygote (CT), homozygote (TT) genotypes and C and T alleles were compared between the patients and controls. A comprehensive analysis of association was conducted between C46T genotypes and the FⅫ:C levels in URSA patients. Results The CC, CT, TT genotypes of the FⅫgene were observed in 7 (3.4%, 7/203), 83 (40.9%, 83/203) and 113 (55.7%, 113/203) patients with URSA versus 7 (4.1%, 7/171), 46 (26.9%, 46/171) and 118 (69.0%, 118/171) controls. The frequency of CT in the patients with URSA was significantly higher than that in controls, but the frequency of TT in the patients was lower than that in controls (χ2=7.939, OR=1.884, 95%CI:1.210-2.935, P<0.05). The frequencies of allele C and allele T were observed in 97 (23.9%, 97/406) and 309 (76.1%, 309/406) patients with URSA versus 60 (17.5%, 60/342) and 282 (82.5%, 282/342) controls. The distribution frequency of allele T in URSA group was lower than that in control group (χ2=4.510, OR=1.475, 95%CI:1.029-2.115, P<0.05). The FⅫ:C levels in the patients were (102±13)%in CC genotype, (78±11)%in CT genotype and (59± 9)%in TT genotype, respectively. The differences of the FⅫ:C levels between the CC and CT, CT and TT, CC and TT genotypes in the patients were significant (all P<0.05). Conclusions The low level of FⅫ:C maybe result from the T allele of the FⅫgene in URSA patients. The CT genotype might be relative to the pathogenesis of URSA in a Chinese Han female population from the southern area of Zhejiang province.

Objective　To investigate the role of bacterial DNA in systemic inflammatory response syndrome (SIRS). Methods　A total of 100 mice of Kunming species were divided into ten groups: E.coli DNA (30, 20, 10, 5 and 1 mg/kg ), 30 mg/kg of CT DNA, 60Co DNA, DNased DNA, organic residue of DNA extraction and sterile water control. The last two were pre-treated with D-galactoamine (600 mg/kg intra peritoneally). Animals were administratively injected via tail vein. General physical condition and the death rate of mice were observed within 48 h. Results　①Obvious lethal effect of double strand E.coli DNA on mice were observed with a dose-effect correlation, LD50=11.51 mg/kg. ②NO difference in death rate was found in the group of 30 mg/kg E.coli DNA with or without 60Co irradiation (10/10 and 8/10,P>0.05). ③No rats died in the group of DNased DNA, organic residue of DNA extraction and calf thymic DNA (0/10). Conclusion　Bacterial DNA may play an important role in the development of SIRS.

Objective: To analyze three events of severe fever with thrombocytopenia syndrome （SFTS） among family members by exposure risk matrix, so as to provide reference for SFTS prevention and control. Methods : The field investigation and clinical data of seven confirmed cases with SFTS reported in Linhai from 2014 to 2016 were collected. Exposure risk matrix was used to list the risk of exposure two weeks before the onset, such as the environment, duration of activity and protection, and evaluate the possible routes of transmission. Results: The first event involved three sisters. Two of them had plucked tea together on a hill, and the possibility of infection through tick bites were 60% and 75%, respectively. Another sister was more likely to be infected by ticks in her residence after visiting her sister （no physical contact with the sick sister）, with a possibility of 74%. The second event involved two cases （mother and son）. They were more likely to be infected by ticks in the current residential area, and the possibility were 100% and 80%, respectively. The third event involved two cases （husband and wife）. The wife had 60% possibility of being infected by the ticks on the hill she picked arbutus, and 40% by the ticks in her residence. The husband was most likely to be infected through contacting with body fluids or blood of his wife （44%）, then through the ticks on the hill he picked arbutus （33%）. Conclusion Among seven cases with SFTS reported in Linhai from 2014 to 2016, six cases have more than 50% possibility of being infected by tick bites; one case has higher possibility of being infected by contacting with body fluids or blood of a patient, but tick bites could not be ruled out.
