ObjectiveUsing large sample clinical study to reevaluate the safety and efficacy of recombinant human growth hormone(ANSOMONE) in treating pediatric growth hormone deficiency(GHD).Methods1012 cases were administered with ANSOMONE at a dose of 0.1 IU · kg-1 · d -1 in bedtime for 6 months.The alteration of mean height,growth rate,height standard deviation scores,bone age,and anti-GH antibody and occurrence of adverse effects were observed.ResultsThe growth rate was promoted from ( 2.50 ± 0.85 ) cm/year to ( 13.44 ± 4.27 ) cm/year,the net growth rate was( 10.94 ±3.69)cm/year.There was significant difference between the pre-treatment and post-treatment patients ( P ＜ 0.01 ).The post-treatment anti-GH antibody positive rate was 13.34％,which had no obvious effect on the efficacy.Few patients exert transient inflammation reactions,which disappeared with any treatment.ConclusionANSOMONE had significant efficacy,and could promote the height increase obviously.It had good safety without any obvious side effect and early-maturing effect.

Objective To define the stages of medical rescue after earthquake or tsunami disaster and their significance.Method Three stages of medical rescue were defined according to the clinical features of diseases in 3-37 days after earthquake or tsunami in Pakistan and Indonesia.The classification of diseases was based on the criteria of disaster medical rescue set by World Health Organization.Five diseases including injuries/wounds,acute upper respiratory tract infection,acute hemorrhagic enterocolitis,acute enterecolitis and other diseases of internal medicine except epidemic or suspected epidemic diseases were employed to define the stages of disaster medical rescue.Results Injuries/wounds mainly occurred in 6 days after disaster.The incidences were 61.45% to 79.52% and 61.48% to 72.35% in Pakistan and Indonesia,respectively.The incidence of acute upper respiratory tract infection reached to a considerably high rate one week after disaster.Other diseases usually appeared one week later with incidence of 33.93% to 71.11% and 31.50% to 52.11% in Pakistan and Indonesia,respectively.The rate of acute hemorrhagic enterocolitis was 2%o in Indonesia whereas 35‰of acute enterocolitis was found in Pakistan.Conclusion Three stages of disaster medical rescue could be well defined.(1)Early or critical stage(in 6 days after disaster):Treatment of injuries/wound and resuscitation was the primary step to deal with.(2)Intermediate of subaeute stage(7-30days following disaster):The incidences of various kinds of diseases increased and more medical resources were needed in order to treat the upper respiratory tract infection and to lower the disable rate,and to prevent the prevalence of epidemic diseases.(3)Later or recovery stage(1-3months after disaster):The general condition of victims became even better than that of those affected by commonly occurred local diseases,and during this period,there were shortages of medical facilities and medical personnel.Therefore,supplement of medical resources was required.The well defined stages of medical rescue have an important significance for medical rescue teams to treat victims and prevent epidemic diseases more efficiently and timely,and also provide a guidance of scientific basis for the logistics officers of local government as well as our government to make a proper and reasonable distribution of medical resources,and dispatch and arrangement of medical rescue teams.This guidance also helps to make victims re- reliant.

On the basis of the Uncaria transcriptome, specific primers were designed for UrSTR. The full-length cDNA of UrSTR (GeneBank: OL310251) was 1 541 bp, encoding 345 amino acid residues, and the promoter region sequence of UrSTR (GeneBank: OL310252) was 1 179 bp. Phylogenetic tree is revealed that UrSTR had a closest relationship with STR from Ophiorrhiza pumila and Ophiorrhiza japonica. Localization of UrSTR protein is revealed located in the vacuole membrane. Plant-care analysis indicated that the promoter region sequence of UrSTR, covering multiple light, stress and hormone-response cis-regulatory elements, and verified transcriptional activity. The results of SDS-PAGE show that pET-28a-UrSTR recombinant protein was successfully expressed, and the size was anticipated. The UrSTR prokaryotic expression system needs to be optimized in the later stage. The research lays the foundation for further purification to study its structure and functional characterization of the UrSTR protein.

OBJECTIVETo sum up the clinical experience in the management of benign prostatic hyperplasia (BPH) with the prostate weighing over 80 ml by transurethral resection of the prostate (TURP) combined with 2 μm continuous-wave laser vaporesection (LVR).

METHODSWe retrospectively analyzed the clinical effects of TURP combined with 2 μm LVR in the treatment of 46 cases of BPH with the prostate volume > 80 ml.

RESULTSAll the operations were successfully accomplished. The operation time and intraoperative blood loss were (112.0 ± 20.0) min (range 86-176 min) and (77.9 ± 25.9) ml (range 50-200 ml), respectively. The catheters were withdrawn at 7 days after surgery. Transient urinary incontinence occurred in 6 cases and secondary hemorrhage was found in 2 postoperatively. Six-month follow-up revealed no urethral stricture or other complications. Compared with the baseline, the international prostate symptom score (IPSS) was significantly decreased at 6 months after operation (26.3 ± 1.8 vs 11.6 ± 1.7, P <0.05), and so were the quality of life (QOL) score (5.3 ± 0.7 vs 1.3 ± 1.1, P <0.05) and post-void residual urine (PVR) ([115.5 ± 55.6] ml vs [19.9 ± 11.6] ml, P <0.05). However, the maximum urinary flow rate (Qmax) was remarkably increased from (4.1 ± 2.6) ml/s to (16.2 ± 1.7) ml/s (P <0.05).

CONCLUSIONTURP combined with 2 μm LVR is safe and effective for the treatment of BPH with the prostate volume >80 ml.

The expression of specific genes in sex chromosomes is the basis of sex-specific membrane protein in mammalian spermatozoa. The gene expression products are shared among spermatozoa through intercellular bridges, however, the phenomena of male transmission-ratio distortion and sex ratio distortion proved that differential proteins exist between X and Y spermatozoa. In addition, the existence of sex-specific proteins was confirmed by the separation experiment of X/Y chromosome bearing spermatozoa and the detection result of sex specific proteins. At the same time, it was also confirmed that the difference of the sex-specific protein is weak . The advance of separation techniques as well as the integration and optimization among these techniques has made it possible to separate sex-specific membrane proteins in mammalian spermatozoa.

OBJECTIVETo determine the mutation responsible for the congenital fibrosis of the extraocular muscles type I(CFEOM1) in a Chinese family.

METHODSDirect sequencing of exons 20 and 21 in the KIF21A gene was performed for the proband. The mutation c.2860C to T in exon 21 was examined by allele specific-PCR (AS-PCR) analysis in other family members. Haplotype analysis was performed using four STR markers (D12S1668, D12S2194, D12S331 and D12S1048).

RESULTSA heterozygous mutation c.2860C to T in the KIF21A gene was identified in all three affected members with CFEOM1. Haplotype analysis suggested that the mutation might derive from maternal germline mosaicism.

CONCLUSIONThis Chinese family with CFEOM1 may be caused by a c.2860C to T mutation in the KIF21A gene.

OBJECTIVEAt present, blood and skin biopsy tissues are used in the fluorescent in situ hybridization (FISH) test for the diagnosis of Down's syndrome, however, the samples are usually obtained invasively. This study explores the value of oral mucosa cast-off cells in the FISH test, as samples obtained non-invasively, for the diagnosis of this disorder.

METHODSPeripheral blood and oral mucosa cast-off cells were sampled for the FISH test in 16 children with suspected Down's syndrome between March 2010 and March 2011. Chromosomal karyotype analysis of peripheral blood lymphocytes ("gold standard" for the diagnosis of Down's syndrome) was also conducted.

RESULTSThe FISH test, in which both peripheral blood and oral mucosa cast-off cells were examined, showed that 14 children had 21-trosomy syndrome and the other 2 children had normal numbers of cromosome 21. The results of the FISH test were the same as the results of the chromosomal karyotype analysis.

CONCLUSIONSUse of the FISH method to test samples of oral musoca cast-off cells is non-invasive and reliable for the diagnosis of Down's syndrome in children, and is hence worthy of recommendation.
