Objective To study the expression of the imprinted gene H19 and IGF-Ⅱ in newborn placenta,and to discuss its influence on the birth body mass of the neonate. Methods The fresh placental tissues from full-term newborn (without trimester of pregnancy complica-tion and placenta and funic abnormality) with normal,high and low birth body mass (12,10 and 8 samples respectively)were collected. The expression of imprinted gene H19 and IGF-Ⅱ mRNA in the placenta were estimated by reakime fluorescence quantitative PCR Results The ex-pression of H19 mRNA in the placenta was negative correlation to the birth body mass (r =-0.403,P = 0.027).The expression of of IGF-H mRNA was positive correlated to the birth body mass (r = 0.444,P = 0.014). The H19 mRNA expression level in the high birth weight neonates (0.21 0.31) was significantly lower than that in the low birth body mass neonates (1.51 2.04)(P= 0.013). But the expression level of IGF-Ⅱ mRNA in the high birth body mass neonates (2.67±3.41) was significantly higher than that in the low birth body mass neonates (0.39±0.33)(P =0.013). Conclusion The expression of H19 and IGF-Ⅱ mRNA was significantly different in the placenta of normal,high and low birth body mass newboms. These two genes may be related to the birth body mass,and there may be some realation-ship between these two genes.

Objective To analyze the clinical characteristics,therapy and follow-up of the patients with ulcerative colitis (UC).Methods Collect the date of 77 inpatients with UC at the Second Affiliated Hospital of Chongqing Medical University be-tween November,2009 and october,2014,and assigned the patients randomly.Results 69.9% of the patients who were in the ac-tivity stage were moderate severity.E2 (46.6%,34/73)and E3 (50.7%,37/73)were the common lesions range.The main clinical manifestations were abdominal pain,diarrhea,mucopurulent bloody stool and bloody stool.The enteroscopy mostly showed that in-testinal mucosa hyperemia,eddma,erosion,and small ulcers had the common features of UC.The common biopsy results were chro-nic inflammation and/or erosion.The average value of serum ALB decreases while the severity of UC patients increases.Drug thera-py was the main treatment of UC.The maintenance therapy was aminosalicylic acid,the effective ratio of treatment is 89.0%(55/73).Conclusion UC treatment plan basically follow the consensus and we should enhance the follow-up of UC patients.

Objective We compared the difference of diagnosing macrosomia using the body mass index (BMI)and body mass,so as to investigate whether BMI play an important role in the diagnosis and management of macrosomia in our clinical work.Methods We analysed 5522 newborns (without any maternal complication)delivered in Shengjing Hospital of China Medical University from Jan.2004 to Apr.2009,all of them were full term,singleton and with the birth body mass larger than 2500 g,among them 4989 were in the group with body mass <4000 g,that was 2510-4000 g.533 cases were in the group of body mass ≥4000 g.By both body mass and length,we got the BMI.According to statistical receiver operating characteristic curve(ROC),we determined the cutoff of BMI for diagnosing macrosomia,in addition the sensitivity and specificity of it. Using this newly gotten BMI cutoff as a method to diagnose macrosomia and analyse the results.Results (1)When the newborns with birth length 40-43 cm.the mean birth body mass was(3010 ±351)g,BMI was(17.0 ±2.7)kg/m2;the newborns with birth length 48-51 cm,the mean birth body mass was(3450 ±313)g,BMI was(13.2±1.4)kg/m2;newborns with birth length 56-60 cm,the mean birth body mass was(4332 ±456)g,BMI was(12.5 ±1.3)kg/m2,The longer the birth length,the larger the birth body mass,while the less BMI.(2)Determined by ROC curve,the BMI value could be used to diagnose macrosomia was 14.2 kg/m2.with sensitivity of 78.4% and specificity of 85.0%, the area of under curve was 0. 892. (3) By the BMI cutoff ( 14. 2 kg/m2 ), 111 macorsomia with birth body mass ≥4000 g were not macrosomia any more (20. 8%, 111/533 ),422 still were macrosomia (79.2% ,422/533) ; while for those birth body mass <4000 g, 728 were macrosomia determined by this BMI cutoff ( 14. 59%, 728/4989 ), 4261 were still not macrosomia ( 85.41%, 4261/4989 ). Using BMI cutoff 14. 2 kg/m2 to diagnose macrosomia, within the group of birth body mass ≥4000 g, their birth length in macrosomia and non macrosomia was (52. 2 ± 1.8) cm and ( 55.6 ± 1.3 ) cm respectively, the difference was significant (P <0. 01 ) ;while within the group with body mass <4000 g, the birth length of macrosomia and non-macrosomia was (49.0 ±2. 2) cm and (50. 8 ±2. 2) cm respectively,the difference was significant as well (P <0. 01 ). The whole incidence of macrosomia was 20. 83% (1150/5522) determined by this BMI cutoff. Conclusions Birth body mass and BMI in determining macrosomia show some bias, and birth length relates with this difference, which suggests birth length maybe play an important role in determine the macrosomia. We suggest it is very necessary to use BMI≥ 14. 2 kg/m2 in the diagnosis and management of macrosomia.

Objective To study the protective effect of the hypothermic brain-protection apparatus on hemorrhagic shock rabbits. Methods Applying the modified Wigger's shock animal model, we observed the effects of a self-developed brain-protecting apparatus on the survival time and vital signs of rabbits. Results Hypothermic brain protection could considerably reduce 60% lipid hyperoxide in brain tissues as compared with that in the control group. It could also decrease heart rate and respiration and hence reduce tissue oxygen consumption. Conclusion Hypothermic brain protection can attenuate the brain lesion and obviously prolong the survival time of hemorrhagic shock animals.

Objective To evaluate the efficacy and safety of specific immunotherapy (SIT) to allergic rhinitis in children.Methods Sixty-four patients with mite allergy allergic rhinitis in children,were divided into two groups by random digits table:treatment group and control group,each group with 32 cases.Treatment group was given SIT with standardized allergen vaccine for 3 years on the basis of symptomatic therapy,control group only received symptomatic therapy.Observation indexs included rhinitis symptoms score,drug score,skin index (SI),serum specificity IgE (sIgE),peripheral eosinophil (Eos) counting,development of asthma and the new sensitization.Results The Eos counting,SI after treatment 3 years in treatment group were significantly better than those before treatment and those in control group after treatment 3 years[(0.14 ± 0.12) × 109/L vs.(0.74 ± 0.18) × 109/L,(0.78 ± 0.36) × 109/L and 1.03 ± 0.13 vs.1.51 ± 0.32,1.51 ± 0.37] (P ＜ 0.01).There was no statistically significant difference in sIgE between two groups (P ＞0.05).The rhinitis symptoms score,drug score in two groups after treatment 1,2,3 years were significantly better than those before treatment (P ＜ 0.01).The rhinitis symptoms score,drug score in treatment group after treatment 1,2,3 years were significantly better than those in control group(P ＜ 0.01).The rate of new sensitization in treatment group was significantly lower than that in control group [3.1％ (1/32)vs.34.4％ (11/32),P ＜ 0.01].Conclusion Keeping long-term SIT is effective and safe for children's allergic rhinitis induced by mite,it also prevents new allergen appeared and allergic rhinitis development for asthma.

OBJECTIVE: To evaluate the efficacy of mite allergen specific immunotherapy (SIT) to patients of allergic rhinitis. METHOD: A total of 102 patients with mite allergy were recruited into the study. They were randomly divided into two groups: SIT group (n = 51) and ST (symptomatic therapy) group (n = 51). They were given SIT with standardized allergen vaccine for 3 years or only symptomatic therapy respectively. Observation items include: rhinitis symptom scores, drug score, skin prick test result, serum specificity IgE (sIgE), peripheral eosinophil counting. The development of asthma and new allergens sensitization was also assessed. RESULT: The blood eosinophil numbers, skin test index, rhinitis symptom scores and drug scores were all decreased significantly after the treatment with SIT for 3 years compared to that of ST group (P < 0.01). Although the level of serum slgE was decreased, no statistic diferences were found. No patients developed asthma in SIT group, and only 2.1% of patients had new allergen sensitization; 17.4% of those in ST group developed asthma, 32.6% had new sensitization. No severe adverse events occurred. CONCLUSION Keeping long-term SIT is effective and safe for patients with allergic rhinitis induced by mite, which can also prevent new allergen sensitization and development for asthma.

OBJECTIVE:To provide a reference for clinical use of anti-tumor adjuvant drugs as is reasonable,effective and economical. METHODS:By retrospective investigation and analysis,the utilization of anti-tumor adjuvant drugs in the oncology department of our hospital during 2010 and 2013 was analyzed statistically in respect of the type,dosage form,consumption amount,DDDs,DDC,DUI etc. RESULTS:The anti-tumor adjuvant drugs in our hospital were dominated by injections,especial-ly domestic drugs,the consumption amount of which accounted for 80% of the total consumption amount of anti-tumor adjuvant drugs each year. The anti-tumor adjuvant drugs were mainly used for symptomatic treatment of various adverse reactions. Drug syn-chronization was relatively good each year,however,excessive use of individual drugs existed. CONCLUSIONS:Anti-tumor adju-vant drugs have relatively better synchronism in the drugs quantities and medication number. However,individual drugs have exces-sive use and other irrational use.

Objective To investigate the value of elasticity score and elasticity strain ratio (SR) in predicting the central lymph nodes metastasis of papillary thyroid microcarcinoma (PTMC). Methods This study conducted a retrospective analysis of ultrasonography ifndings of 236 thyroid lesions from 208 patients. All of them underwent surgery in Ruijin Hospital of Shanghai Jiao Tong University from June 2012 to March 2013. Totally 82 PTMC from 82 patients were included in this study. Among them 12 patients with 12 PTMC had central lymph nodes metastasis. The elasticity score and SR were compared between metastasis and non-metastasis groups, and the receiver operating characteristic (ROC) curve of SR was calculated. Results The differences of PTMC elasticity score between two groups showed no statistical signiifcance (χ2=5.00, P=0.08). The average SR of the group with central lymph nodes metastasis is 2.44±0.61, which is higher than the group without lymph nodes metastasis whose average SR is 1.67±0.42. Differences are statistically signiifcant (t=5.5, P=0.00). The area under curve of SR-ROC curve was 0.847. Using 2.01 as cutoff of SR, the sensitivity, speciifcity, accuracy of predicting central lymph nodes metastasis was 83.3%, 81.4%, 78.6%respectively. Conclusion The SR but not elasticity score could be a meaningful indicator for predicting lymph nodes metastasis.
