OBJECTIVETo investigate the growth status of children under 7 years in Wuzhong City, Ningxia Hui Autonomous Region, China and its influential factors, and to provide a basis for related intervention measures.
METHODSChildren under 7 years were selected from two county-level districts in Wuzhong by stratified cluster sampling, and their growth status were evaluated by the Z score method.
RESULTSThe prevalence rates of growth retardation, underweight, and wasting were 12.58%, 5.71%, and 5.55% respectively. The height-for-age Z score, weight-for-age Z score, and weight-for-height Z scores were -0.26±2.50, 0.29±4.54. and 0.65±3.02 respectively. There were significant differences in the prevalence rate of wasting among children of different ethnic groups (P<0.05); also, there were significant differences in the prevalence rates of growth retardation and underweight among children from different regions and with different age (P<0.05). The main influential factors for growth retardation were region (OR=0.369, P<0.001), ethnic groups (OR=1.694, P=0.027), and age (OR=1.143, P=0.002). The main influential factors for underweight were region (OR=0.453, P=0.001) and age (OR=1.204,P=0.002). The main influential factor for wasting was nation (OR=1.735, P=0.024).
CONCLUSIONSIn Wuzhong, children under 7 years have poor growth status, which are related to ethnic groups, region, and age.

OBJECTIVETuberculosis remains a severe public health issue, and the Beijing family of mycobacterium tuberculosis (M. tuberculosis) is widespread in East Asia, especially in some areas in China, like Beijing and Tianjin. This study aimed at determining the mutation patterns of drug-resistant Beijing strains of M. tuberculosis isolated from Tianjin, China.
METHODSA total of 822 M. tuberculosis isolates were screened for drug resistance by an absolute concentration method and the genotype was identified by PCR. 169 drug-resistant isolates of the Beijing family were analyzed for the potential mutations in the rpoB, katG, inhA promoter region and in rpsL, rrs and embB genes, which are associated with resistance to rifampin (RFP), isoniazid (INH), streptomycin (SM) and ethambutol (EMB) respectively by PCR and DNA sequencing.
RESULTSFifty-eight out of 63 RFP-resistant isolates were found to carry the mutations within the 81-bp RFP resistance determining region (RRDR) of the rpoB gene and the most frequent mutations occurred at codon 531 (44.4%), 526 (28.6%), and 516 (7.9%) respectively. 16 mutation patterns affecting 12 different codons around the RRDR of rpoB were found. Of 116 INH-resistant isolates, 56 (48.3%) had the mutation of katG 315 (AGC-->ACC) (Ser-->Thr), 3 (2.6%) carried S315N (AGC-->AAC) and 27 (16.0%) had the mutation of inhA-15A-->T. 84 out of 122 SM-resistant isolates (68.9%) displayed mutations at the codons 43 or 88 with AAG-->AGG (Lys-->Arg) of the rpsL gene and 22 (18.0%) with the mutations at positions 513A-->C, 516C-->T or 905 A-->G in the rrs gene. Of 34 EMB-resistant isolates, 6 had mutation with M306V (ATG-->GTG), 3 with M306I (ATG-->ATT), 1 with M306I (ATG-->ATA), 1 with D328Y (GAT-->TAT), 1 with V348L (GTC-->CTC), and 1 with G406S (GGC-->AGC) in the embB gene.
CONCLUSIONThese novel findings extended our understanding of resistance-related mutations in the Beijing strains of M. tuberculosis and may provide a scientific basis for development of new strategies for diagnosis and control of tuberculosis in China and other countries where Beijing strains are prevalent.

OBJECTIVETo explore the potential role of miR-195 on invasiveness and prognosis of breast cancer.
METHODSThe RNA in formalin-fixed paraffin embedded (FFPE) of 88 breast cancer patients with primary tumors was extracted, and miR-195 levels were quantified by quantitative real-time polymerase chain reaction (real-time PCR). The relationship of miR-195 levels and clinicopathological variables were assessed by Mann Whitney-U test. Recurrence-free survival and overall survival curves were derived from Kaplan-Meier estimates and the curves were compared by Log-rank tests. Cox regression analysis was used for multivariate analysis. All statistical tests were two-sided.
RESULTSThe levels of miR-195 in the breast cancer with histological high grade, tumor size of T3-4, lymph nodal involvement or vessel invasion were significantly down-regulated, compared with those of patients with histological low grade (Z = -2.271, P = 0.023), tumor size of T1-2 (Z = -2.687, P = 0.007), no lymph node metastasis (Z = -1.967, P = 0.049) and vessel invasion (Z = -2.432, P = 0.015). In addition, no statistically significant difference (P > 0.05) was identified between miR-195 levels and hormone receptors status, HER-2 expression, TNM stage, tumor types, recurrence and menstrual status. When considering 2(-ΔCt) = 0.270 (median level) as cut-off value, Kaplan-Meier survival analysis indicated that patients with high miR-195 level showed a positive association towards a longer survival, either recurrence-free survival (χ(2) = 5.985, P = 0.014) or overall survival (χ(2) = 30.05, P = 0.000). In a multivariate analysis, miR-195 expression on FFPE correlated significantly with outcomes of breast cancer (HR = 0.040, 95%CI: 0.009 - 0.179, P = 0.000) and was independent of other prognostic factors.
CONCLUSIONSIt suggests that miR-195 expression on FFPE is inversely correlated with histological high grade, bigger tumor size, lymph node involvement, vessel invasion. Furthermore, as independent prognostic factor, low miR-195 significantly contributes to poor outcomes of breast cancer.

OBJECTIVEStudying the gene expression profiling of different stage hairy root of Salvia miltiorrhiza, in order to find functional genes.
METHODThe contents of second metabolites were determined by HPLC and gene expression profiling was detected by cDNA microarray. cDNA labeled with a fluorescent dye (Cy5 and Cy3-dCTP) was produced by Eberwine's linear RNA amplification method and subsequent enzymatic reaction. The microarrays were scanned with a ScanArray Express scanner using ScanArray 2.0 software and quantified by signal intensities of individual spots from the 16-bit TIFF images using GenePix Pro 4.0. The linear normalization method was used for data analyze. Northern blot was used to test the gene expression results obtained by microarray. Different expressed genes were sequenced and analyzed by gap4 software, and then they were analyzed with BLASTX, BLASTN, GO and KEGG.
RESULTGrowth rate and second metabolites analysis indicated that the stage from 30 d to 45 d was the growth stage, while the stage from 45 d to 60 d was the second metabolites accumulation stage. Accordingly 30 d hairy root was chosen as a reference, which was hybridized with 45 d and 60 d hairy root separately. Total 203 different expressed genes were obtained. Northern blot showed that the result was identical with the microarray result. After sequenced, there were 172 genes clustered into 114 clusters (Unigenes). Among them, 62 unigenes had known functions, 34 unigenes were hypothetical protein, 9 unigenes were homologues with no similarity and 9 unigenes were unidentified protein with low similarity. Total 67 genes were classified into cellular component ontology, molecular function ontology and biological process ontology based on GO analysis. Total 26 genes, which represented 29 metabolic-related enzymes, were located in metabolic maps based on KEGG pathway classification.
CONCLUSIONSeveral important functional genes related to second metabolite synthesis were cloned such as P450 and copalyl diphosphate synthase genes. cDNA microarray was a useful tool for functional genomics of traditional Chinese medicine.

OBJECTIVESTo measure continuously the urine beta-FSH excretion in the patients with male hypogonadism, and to evaluate the significance of urine beta-FSH when used in the clinical practice and pathophysiological study on male hypogonadism.
METHODSFour health male volunteers (aged 19, 22, 27 and 33 years), four patients with the hypogonadotropic hypogonadism (aged 17, 17, 19 and 24 years) and five patients with idiopathy hypogonadism (hypergonadotropic, aged 16, 16, 17, 20 and 22 years) were asked to collect their morning-first urine samples for 30 to 32 days. One normal men collected his urine samples for 63 days. The urine beta-FSH was assayed with the method of EIA, then corrected by creatinine (Cr) concentration.
RESULTSThe urine beta-FSH level of normal men was (1.16 +/- 0.20) micrograms/mg Cr, with the peak variation in their curves, peak level at 2.76 micrograms/mg Cr. The levels of urine beta-FSH of 4 patients with the hypogonadotropic hypogonadism were lower significantly than those of normal men [(0.58 +/- 0.31) (0.93 +/- 0.47) (0.47 +/- 0.33) and (0.60 +/- 0.40) micrograms/mg Cr], without fluctuation in their curves. beta-FSH levels of 5 patients with idiopathy hypogonadism were higher significantly [(3.02 +/- 0.93), (4.36 +/- 1.12), (4.79 +/- 0.78), (4.64 +/- 1.42) and (3.88 +/- 1.42) micrograms/mg Cr], with irregular fluctuation, the highest peak level at 6.83 micrograms/mg Cr. The second sexual characteristics of hypogonadal patients were poor and serum testosterone levels low.
CONCLUSIONSThe urine beta-FSH level raised with irregular fluctuation in patients with idiopathy hypogonadism, while lowed without any fluctuation in patients with the hypogonadism. These findings suggested that the urine beta-FSH excretion was useful for the clinically classified diagnoses and pathophysiological study on male hypogonadism, and for observing the treatment reaction of androgen replacement.

OBJECTIVETo investigate the effects of electromagnetic radiation on the physiological indices and immune function of operators.
METHODSThe general conditions and electromagnetic radiation awareness rate of 205 operators under electromagnetic radiation were evaluated using a self-designed questionnaire. Physical examination, electrocardiography, and routine urine test were performed in these operators. Peripheral blood was collected from the operators under electromagnetic radiation for blood cell counting and biochemical testing, and their peripheral blood lymphocytes were cultured for determination of chromosomal aberrant frequency and micronucleus frequency. The data from these operators (exposure group) were compared with those of 95 ordinary individuals (control group).
RESULTSThe chief complaint of giddiness, tiredness, dizziness, and amnesia showed significant differences between the exposure group and control group (P < 0.01), and the difference in headache became larger with an increase in working years. The awareness rate of electromagnetic radiation damage was significantly higher in the exposure group than in the control group. The difference in bradycardia was significant between the two groups (P <0.01), and the incidence was higher with longer working years. Significant differences between the two groups were also found in the numbers of individuals with elevated alanine aminotransferase, total bilirubin, and direct bilirubin (P < 0.01), populations with increased lymphocyte ratio and decreased neutrophil ratio (P < 0.01), populations with positive occult blood, urobilinogen, and bilirubin tests, and the number of individuals with increased micronucleus frequency of cultured peripheral blood lymphocytes (P < 0.01). In addition, the exposure group had significantly increased complement C3 and C4 (P < 0.01), significantly increased IgG (P < 0.05), and significantly decreased IgM (P < 0.01), as compared with the control group.
CONCLUSIONElectromagnetic radiation may lead to the changes in physiological indices, genetic effects, and immune function and affect the health and immune function in operators. The adverse effects are increased as the working years increase. So it is important to strengthen occupational protection of operators under electromagnetic radiation.

This study was aimed to investigate the therapeutic efficacy of rabbit anti-thymocyte globulin (r-ATG) combined with cyclosporine A (CsA) and to analyse the efficacy-related factors in children with aplastic anemia (AA). Twenty five AA children treated with r-ATG [3.5 mg/(kg·d)×5 days] combined with CsA were analyzed retrospectively. The lymphocyte subgroups, CD4(+)/CD8 ratio and expression of CD55, CD59 on surface of neutrophils and erythrocytes in peripheral blood were detected by direct immunofluorescence method and flow cytometry; the responsive time, effective rate, adverse effects and infections after immunosuppressive therapy (IST) were analyzed; the distribution of T-lymphocyte subgroups in IST-effective and IST-uneffective groups was compared, and therapeutic efficacy-related factors were evaluated. The results showed that the response to treatments was found in 21 out of 25 cases, the total responsive rate was 84.0%; the response time was 3 - 6 months, average of 4 months; the effective rates in month 3, 6, 9, 12 after treatment were 56.0%, 72.0%, 80.0% and 84.0% respectively. The AA children with age ≥ 5 years old, course of disease < 6 months and absolute neutrophil value ≥ 1.5 ×10(9)/L on 30 days after IST had good curative effect; the effective rate in AA children with age ≥ 5 years old, course of disease < 6 months, high or reverse ratio of CD4(+)/CD8(+) and absolute neutrophil value ≥ 1.5×10(9)/L after IST was higher than that in AA children with age < 5 years old, course of disease ≥ 6 months, normal ratio of CD4(+)/CD8(+) and absolute neutrophil value after IST < 1.5×10(9)/L (94.4% vs 57.1%, 90.4% vs 50.0%, 94.1% vs 62.5%, 94.1% vs 62.5%) (P < 0.05). The high effective rate was observed in AA children with decrease of CD55 and CD59 expression, but there was no significant difference (P > 0.05) as compared with normal expression of CD55, CD59. It is concluded that the treatment using r-ATG (3.5 mg/kg·d × 5 d) combined with CsA is a safe and effective for children with AA. Age, course of disease and absolute neutrophil value on 30 days after IST are the main factors affecting curative affect.
