Recent studies have shown that pituitary hormones, including thyroid stimulating hormone (TSH), follicle stimulating hormone(FSH), adrenocorticotropic hormone(ACTH), and oxytocin(OT)may actually bypass their target endocrine organs and affect the skeleton directly. Therefore, a new conception, pituitary-bone axis is proposed. This breakthrough sheds a new light on the function of pituitary hormones and the pathogenesis of osteoporosis associated with hyperthyroidism, menopause or pregnancy, and even osteonecrosis after using glucocorticoids. In addition, it is conducive to give the reference guidance for clinical treatment of metabolic bone diseases and new drug development.

With dramatic decline of genome sequencing cost,high-throughput sequencing technologies have been applied in clinical laboratory field,and play an increasingly important role in clinical diagnosis and treatment in complex diseases.Based on omics techniques,clinical laboratory data recording patient's diagnosis information has become the important independent medical research resources of the major health industry.Because these data include the patient's identity information,there are a series of ethical issues to be solved,such as protection of patients' informed consent right,patient privacy protection,information security protection,when carrying out the medical health big data research.Based on these problems,it proposed clinical laboratory data should be standard extraction,establishment of clinical laboratory data base for teaching,training,in order to improve the utilization of medical resources.Moreover,it is best to implement the written informed consent during the process of sample collection,informing the patient the data collected in diagnosis and treatment process may be used in related research in future.

Antibody arrays, as a specific subset of protein arrays,are now used in a wide variety of applications. Although having evolved into indispensable tools for proteomic studies, they seems to be still at the middle point on the way to the final destination to have the antibody arrays with high sensitivity, minimized size and wide dynamic detection range to meet the needs for the detection of different samples. This article reviewed the recent development regarding how to improve the detection sensitivity of the antibody arrays.

Objective:To explore the relationship between the polymorphisms in gene FGFR1, FGF10, FGFI8 and the nonsyndromic cleft lip with or without cleft palate (NS CLP) in Chinese population. Methods: Genomic DNA was isolated from peripheral lymphocytes of 75 patients with NS CLP and their parents and 75 unimpaired healthy children. The polymorphisms in FGFRI gene rs13317, p. E467K, p. M3691 and p. S393S, FGF10 gene rs1448037 and FGFI8 gene rs4043716 were detected by applying three-dimensional (3-D) polyacrylamide gel microarray technology. The data were performed using statis-tical analysis : the genotype frequenc+ y and allele frequency between patients with NSCL/P and control subjects were performed. Haplotype relative risk (HRR) , family based association test (FBAT) , and transmission disequilibrium test (TDT) in nuclear family were performed. Results: There were no poly-morphism in FGFR1 gene p. E467K, p. M369I and p. $393S site, the corresponding base was all G. The polymorphisms of rs13317 and rs1448037 were detected and their genotype frequency and allele frequen-cy showed no significant difference between 75 patients with NSCL/P and 75 normal children. TDT, HRR and FBAT were also no significant differences. The genotype frequency of gene FGF18 rs4043716 showed significant difference, but allele frequency were no significant difference. TDT, HRR and FBAT were also no significant difference. Conclusion: Our studies suggest an association between gene FGF18 rs4043716 and the NS CLP in Chinese population, and no association among gene FGFR1 rs13317, p. FA67K, p. M3691, p. S393S and gene FGF10 rs1448037.

OBJECTIVETo analyze interpersonal sensitivity level and influencing factors among patients in methadone maintenance treatment.

METHODSFrom 2010 June to 2011 June, the research was performed in Center of Methadone Maintenance Treatment of Nanjing Baixia District Hospital. A total of 272 methadone maintenance treatment was studied using a self-designed questionnaire, interpersonal sensitivity scale in symptom check list (SCL-90), self-rating depression scale (SDS), self-rating anxiety scale (SAS). If interpersonal sensitivity level ≥ 2 points, it was positive. In this study, through independent sample t test, analysis of the social demographic characteristics, depression and anxiety, interpersonal sensitivity level. Non conditional logistic regression analysis was used to explore a variety of factors, and the relationship of these factors with interpersonal sensitivity.

RESULTSThe depression score, the anxiety score and the level of interpersonal relationship sensitivity in 272 methadone maintenance treatment (1.65 ± 0.51, 47.66 ± 8.58, 42.38 ± 9.40) was higher than the national norm (1.65 ± 0.51, 41.88 ± 10.57, 29.78 ± 0.46) (t values were 8.23, 17.63 and 22.27, respectively; all P values < 0.001). In 272 methadone maintenance treatment, the percentage of men was 75.0% (204/272) and the percentage of women was 25.0% (68/272). SDS score of male and female was (48.38 ± 8.30) and (45.90 ± 9.34) points (t = 5.67, P = 0.037); Aged 20-29, 30-39, 40-49 and ≥ 50 years old group, SDS scores were (48.26 ± 7.59), (47.73 ± 8.38), (47.79 ± 9.22) and (48.09 ± 6.33) points (F = 3.90, P = 0.046); According to the drug's time, divided into 1-3, 4-6 and ≥ 7 years group, SDS scores were (45.92 ± 7.47), (47.41 ± 7.57) and (48.07 ± 8.57) points (F = 4.49, = 0.039). SAS score of male and female was (41.21 ± 9.53) and (42.91 ± 9.42) points (t = 2.23, P = 0.043). The positive rate of interpersonal sensitivity was 47.1% (128/272). Multivariate analysis showed that, with SDS and SAS scores increased by 1, respectively, interpersonal sensitivity increased 23.23 (8.62-96.68) and 11.97 (6.42-19.27) points.

CONCLUSIONInterpersonal sensitivity level in methadone maintenance treatment was higher than normal and depression; anxiety and depression both were the risk factors of interpersonal sensitivity level.

BACKGROUNDThe importance of polymorphisms in the methylenetetrahydrofolate reductase (MTHFR) gene for the prediction of the response to fluorouracil-based adjuvant chemotherapy in gastric cancer patients remains unclear. The aim of this study is to assess the predictive value of several polymorphisms of the MTHFR gene for clinical outcomes of gastric cancer patients treated with fluorouracil-based adjuvant chemotherapy in Chinese population.

METHODSThree hundred and sixty-two Chinese patients with gastric cancer were treated with fluorouracil-based adjuvant chemotherapy. DNA samples were isolated from peripheral blood collected before treatment. The three single nucleotide polymorphisms (SNPs) (rs1801131, rs1801133, rs2274976) genotypes of the MTHFR gene were determined by matrixassisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS).

RESULTSThe average response rate for chemotherapy was 46.7%. Homozygous genotypes rs2274976G/G (χ(2) = 22.7, P < 0.01) and rs1801131A/A (χ(2) = 14.3, P = 0.008) were over-represented in responsive patients. Carriers of the rs2274976A allele genotypes (G/A and A/A) and of the rs1801131C allele genotypes (A/C and C/C) were prevalent in nonresponsive patients. In the haplotype association analysis, there was a significant difference in global haplotype distribution between the groups (χ(2) = 20.69, P = 0.000 124).

CONCLUSIONSThese results suggest that polymorphisms of the MTHFR gene may be used as predictors of the response to fluorouracil-based chemotherapy for gastric cancer patients in Chinese population. Well-designed, comprehensive, and prospective studies on determining these polymorphisms of MTHFR gene as clinical markers for predicting the response to fluorouracil-based therapy in gastric cancer patients is warranted.
