As one of the earliest markers for predicting pregnancy outcomes,human chorionic gonadotropin (hCG) values have been inconclusive on reliability of the prediction after frozen and fresh embryo transfer (ET).In this retrospective study,patients with positive hCG (day 12 after transfer) were included to examine the hCG levels and their predictive value for pregnancy outcomes following 214 fresh and 1513 vitrified-warmed single-blastocyst transfer cycles.For patients who got clinical pregnancy,the mean initial hCG value was significantly higher after frozen cycles than fresh cycles,and the similar result was demonstrated for patients with live births (LB).The difference in hCG value existed even after adjusting for the potential covariates.The area under curves (AUC) and threshold values calculated by receiver operator characteristic curves were 0.944 and 213.05 mIU/mL for clinical pregnancy after fresh ET,0.894 and 399.50 mIU/mL for clinical pregnancy after frozen ET,0.812 and 222.86 mIU/mL for LB after fresh ET,and 0.808 and 410.80 mIU/mL for LB after frozen ET with acceptable sensitivity and specificity,respectively.In conclusion,single frozen blastocyst transfer leads to higher initial hCG values than single fresh blastocyst transfer,and the initial hCG level is a reliable predictive factor for predicting IVF outcomes.

OBJECTIVETo compare the clinical efficacy in the treatment of allergic rhinitis (AR) of lung qi deficiency and cold syndrome between Jin's three-needle therapy and western medication.

METHODSSixty-six patients were randomized into an acupuncture group and a western medication group, 33 cases in each one. In the acupuncture group, acupuncture was applied at three-nose points [Yingxiang (LI 20), Shangyingxiang (EX-HN 8) and Yintang (GV 29); Cuanzhu (BL 2) was added for frontal headache] and three-back points [Dazhu (BL 11), Fengmen (BL 12) and Feishu (BL 13)], once every day. Ten treatments made one session. Two sessions of treatment were required. In the western medication group, desloratadine oral suspension was prescribed, 5 mg each time, once a day, for 20 days. The scores of the symptoms and physical signs in AR patients as well as the clinical efficacy were observed between the two groups.

RESULTSThe total effective rate was 93.9% (31/33) in the acupuncture group, which was better than 72.7% (24/33) in the western medication group (P < 0.05). After treatment, the scores of AR symptoms and physical signs as well as the total score were all reduced compared with those before treatment in the two groups (all P < 0.01). The score of every item in the acupuncture group was lower than that in the western medication group after treatment (score of symptoms: 4.70 +/- 2.07 vs 6.55 +/- 2. 69, score of physical signs: 0.85 +/- 0.67 vs 1.45 +/- +0.62, total score: 5.36 +/- 2.70 vs 8.00 +/- 2.91, all P < 0.01).

CONCLUSIONJin's three-needle therapy achieves superior efficacy on AR of lung-qi deficiency and cold syndrome, which is better than desloratadine oral suspension.

OBJECTIVETo establish the Chinese Pediatric Evaluation of Disability Inventory (PEDI) norms in Chongqing, China.

METHODSPEDI (English version) was translated into Chinese and proof read by back-translation. A total of 1 140 children stratified by age were randomly selected from Chongqing and evaluated by the Chinese version of the PEDI. The obtained data were statistically analyzed.

RESULTSOf 1 140 questionnaires, 1 075 (94.3%) were valid. The data showed that the raw and scale scores of PEDI increased with age, but the standard scores did not increase with age. The raw, scale, and standard scores on self-care and social function scales were significantly lower than American PEDI norms in some age periods (P<0.05), but the raw, scale, and standard scores on mobility scale were not significantly different from American norms (P>0.05).

CONCLUSIONSThe PEDI norms in Chongqing have been successfully established, and can be used to assess the daily function in children, judge the degree of daily function impairment, evaluate the effect of rehabilitation training, and make the rehabilitation plan for disabled children.

OBJECTIVETo explore the relationship between G2139A,G3091A, T663A, and T3593C single nucleotide polymorphisms (SNPs), which are located at the promoter region,13th exon, and 2nd intron of epithelial sodium channel (ENaC) gene, and their haplotypes with essential hypertension (EH) in Kazakhs in Xinjiang.

METHODSA case-control study was conducted including 252 EH patients (EH group) and 254 normotensive subjects (NT group) among Kazakhs in Xinjiang. The four genetic polymorphisms were identified by polymerase chain reaction - restriction fragment length polymorphism. The distribution of the genotypes and alleles in all subjects and the different frequency of these four SNPs between EH group and NT group were analyzed. The linkage disequilibrium and haplotypes of these four SNPs were analyzed.

RESULTSThese four SNPs of alpha ENaC gene existed in Xinjiang Kazakhs. In all subjects, the distribution frequencies of genotypes AA, AG, and GG at G2139A were 26.2%, 52.3%, and 21.5%, respectively, and those of alleles (A, G) were 52.37% and 47.63%. The distribution frequencies of genotypes AA, AG, and GG at G3091A were 19.0%, 52.5%, and 28.5%, respectively, and those of and alleles (A, G) were 45.56% and 59.44%. The distribution frequencies of genotypes AA, AG, and GG at T663A were 15.6%, 49.9%, and 34.5%, respectively, and those of alleles (A, G) were 40.53% and 59.47%. The distribution frequencies of genotypes TT, TC, and CC at T3593C were 88.5%, 10.5%, and 1.0%, respectively, and those of alleles (T, C) were 93.77% and 6.23%. The distribution of genotypes at these four SNPs were all consistent with Hardy-Weinberg equilibrium in this population (P0.05). The distribution frequencies of genotypes and alleles about these four genetic polymorphisms were not significantly different between the EH group and NT group (P0.05). However, the frequencies of two haplotypes were found to be significantly different between these two groups (P0.05). The haplotype frequency which included 2139G, 3091A, 663G, and 3593T alleles was significantly increased in EH group (P0.01), while the haplotype frequency which included 2139A, 3091A, 663A, and 3593C alleles was significantly increased in NT group (P0.05).

CONCLUSIONSThe haplotypes that are composed of G2139A, G3091A, T663A, and T3593C polymorphisms of alphaENaC gene may play an important role in the development of EH among Kazakhs in Xinjiang. The haplotypes that are composed of 2139G, 3091A, 663G, and 3593T alleles may aggravate the development of EH. The haplotypes that composed of 2139A, 3091A, 663A, and 3593C alleles may decrease the risk of EH among Kazakhs.

Objective To study the effect of ulinastatin on no reflow or slow flow in the infarct related artery in patient with acute ST-elevation myocardial infarction (STEMI) undergoing emergency percutaneous coronary interventional therapy (PCI).Methods 180 STEMI patients were divided into the control group (n=100) and the ulinastatin treatment group (n=80).The control group received conventional PCI treatment and the treatment group received conventional PCI treatment plus ulinastatin. The level of serum inflammatory factors IL-6,IL-10,superoxide converting enzyme,the infarct related coronary artery reperfusion TIMI flow grade (TFG) and myocardial perfusion grade (TMPG),the results of postoperative cardiac ultrasound examination and clinical outcomes were compared between the two groups.Results Compared with the control group,the level of IL-6 was decreased,while the levels of IL-10 and superoxide converting enzyme were increased significantly in the ulinastatin treatment group(P<0.05).The TFG and TMPG of the infarct related vessels were increased significantly in the ulinastatin treatment group. The left ventricular end diastolic diameter[(54.6 ± 5.2 mm vs. (50.4±4.6) mm,P=0.046)]and left ventricular ejection fraction [(58.4±10.2) % vs. (62.2±9.8) % P=0.048] showed statistical difference between the two groups.Compared to the control,the major cardiovascular event rate of the treatment group during hospitalization (1% vs. 5%, P=0.038), after one month (1.2% vs. 3%,P=0.046) and 6 months (3% vs 12%,P=0.018) were all significantly lower .There was no significant difference in mortality between the 2 groups.Conclusion Ulinastatin may lower the incidence of no flow and slow flow after emergency PCI,improve heart function and the lower the rates of MACE.

OBJECTIVETo investigate the expression of T-bet mRNA in peripheral blood mononuclear cells (PBMC) as well as its relations with total IgE (TIgE), eosinophil cationic protein (ECP) in serum and nasal allergic symptoms in patients with allergic rhinitis (AR).

METHODSThe allergen, TIgE and ECP in serum of patients with AR were detected by Unicap CAP system. Blood sample was taken from 8 healthy individuals and 22 patients with allergic rhinitis. PBMC was isolated by density gradient centrifugation and one part of them was cultured with 50 microg/ml mite allergen. PBMC was subjected to analysis of T-bet mRNA expression using semiquantitative reverse transcriptase-polymerase chain reaction (RT-PCR).

RESULTSThe ratio of T-bet to beta-actin mRNA levels was 0.381 +/- 0.099 in patients and 0.750 +/- 0.067 in normal individuals, the difference was significantly (P <0.01). The expression intensity of T-bet mRNA had no relation to varying severity of allergic symptoms and concentration of ECP and the correlation coefficient was 0.187 and -0.165 (all P > 0.05). However, there was an inverse correlation between expression intensity of T-bet mRNA and TIgE concentration (r = -0.525, P < 0.05). Mean mRNA level (x +/- s) of T-bet expression before and after being stimulated by allergen was 0.381 +/- 0.099 and 0.365 +/- 0.104 respectively, which indicated no significant differences (P > 0.05).

CONCLUSIONSAmong allergic patients whose allergen was mite, there was a down-regulated expression of T-bet mRNA, which had no relation to ECP concentration and allergic symptoms, but was one of important links in mechanisms of imbalance of Th1/Th2 in AR. There was no effect of specific allergen on T-bet mRNA in patients with AR T-bet was one of indirect factors that affected the level of IgE.

OBJECTIVE: To study the clinical efficacy of interactive group sandplay versus individual sandplay in the treatment of preschool children with autism spectrum disorder (ASD). METHODS: A total of 80 ASD children, aged 4-6 years, were enrolled and randomly divided into experimental and control groups, with 40 children in each group. The children in the experimental group joined group sandplay with normal children at a ratio of 1: 3, and those in the control group were treated with individual sandplay. The Aberrant Behavior Checklist (ABC) and Autism Treatment Evaluation Checklist (ATEC) were used to evaluate the treatment outcome after three months of intervention. RESULTS: There were 33 children in the experimental group and 28 in the control group. After three months of intervention, the experimental group had significant reductions in the scores of irritability, social withdrawal, and stereotypic behavior and the total score of the ABC scale (P<0.05), and the control group had significant reductions in the scores of behavior and inappropriate speech and the total score of the ABC scale (P<0.05). Compared with the control group, the experimental group had significantly greater improvements in the score of social withdrawal and the total score of the ABC scale after three months of intervention (P<0.05). After three months of intervention, the experimental group had significant reductions in the scores of sociability, sensory and cognitive awareness, and physical/health behavior and the total score of the ATEC scale (P<0.05), and the control group had significant reductions in the scores of speech, sociability, and physical/health behavior and the total score of the ATEC scale (P<0.05). Compared with the control group, the experimental group had significantly greater improvements in the scores of speech, sociability, and sensory and cognitive awareness and the total score of the ATEC scale after intervention (P<0.01). Compared with the control group, the experimental group also had significantly greater improvements in eye contact and sand stereotyped arrangement (P<0.05). CONCLUSIONS Both interactive group sandplay and individual sandplay are effective in the treatment of ASD in preschool children. Interactive group sandplay is better than individual sandplay in the treatment of ASD, with significant improvements in sociability, emotion and stereotypic behavior.

OBJECTIVETo explore the relationship between gene polymorphism of GABAA receptors and childhood autism by detecting rs140682, rs2081648 and rs140679 site of single nucleotide polymorphism (SNP) in GABAA receptors gene.

METHODSA total of 94 children with autism and 124 normal children were enrolled in a hospital from November 2010 to May 2011. Childhood autism rating scale (CARS) and autism behavior checklist (ABC) were used to evaluate or investigate the case group. After collecting venous blood and extracting the genome DNA, the allele and genotype of SNP rs140682, rs2081648 and rs140679 site in GABAA receptors gene were detected by PCR-RFLP. The allele and genotype of case group and control group were analyzed by χ(2) test, while the score of scales was analyzed by Spearman rank correlation analysis.

RESULTSThe age of the case group was 5.12 ± 0.32, and it was 5.25 ± 0.27 in the control group (P < 0.05). In case group, the frequency of genotype CC, CT and TT of rs140682 site was 44, 41 and 9, while it was 48, 65, and 11 in control group (P > 0.05), respectively. The frequency of genotype AA, AG and GG of rs2081648 site was 8, 58 and 28 in case group, while it was 12, 49 and 63 in control group (P < 0.05), respectively. In case group, the frequency of genotype CC, CT and TT of rs140679 site was 15, 36 and 43, while it was 18, 59 and 47 in control group (P > 0.05), respectively. It was revealed by Spearman rank correlation analysis that of rs2081648 site, there was a positive correlation between genotype AG and sensation factor (S), social intercourse factor (R), and language factor (L) of autism behavior checklist (ABC) (r values were 0.149, 0.165 and 0.155, all P values < 0.05). A negative correlation between genotype GG and S, R, L and self-help factor (V) was proved (r values were -0.140, -0.173, -0.158 and -0.135, all P values < 0.05). There was a positive correlation between allele A and R and L factors (r values were 0.153 and 0.137, all P values < 0.05), while a negative correlation between allele G and R and L factors (r values were -0.153 and -0.137, all P values < 0.05). In case group, 42 children were diagnosed with mild-to-moderate autism, while 52 children were severe autism. There was no statistically significant correlation between allele or genotype of SNP rs140682 and rs140679 site and the degree of autism (P > 0.05). There was a positive correlation between allele A and genotype AG and the degree of autism (r values were 0.147 and 0.616, all P values < 0.05), while a negative correlation between allele G and genotype GG and the degree of autism (r values were -0.159 and -0.616, all P values < 0.05).

CONCLUSIONThe SNP rs2081648 site which located in GABAA receptors gene may be related to autism. No evidence for significant association between rs140682 and rs140679 site and autism was found.
