Objective To investgate the changes of bone mineral density (BMD) and biochemical markers of bone metabolism in elderly male patients with osteoporosis (OP) . Methods BMD and bone mineral content (BMC) of the lumbar spines (L 2～4 ) and the biochemical markers of bone metabolism in serum and urine were measured. Results BMD and BMC in OP group was reduced by 21.6% and 25% respectively vs that in control group. Bone formation indicators of serum levels of ALP and BGP in OP group were increased by 25.4% and 222% respectively vs that in control. At the same time, bone resorption indicators of urine Hop/Cr and NTX/Cr ratios were significantly increased by 22.6% and 223% in OP group than that in control. Serum T level of OP group was lower than that in control group and serum 25 OH D3 was below the normal value in both groups. Conclusions BMD and BMC of the lumbar spines (L 2 4 ) are the main basis for diagnosing the osteoporosis in men. Some elder male patients with osteoporosis are due to high turnover of bone metabolism. Androgen plays an important part in maintaining the bone mass. Vitamin D deficiency in elder men is the main reason occurring osteoporosis.

OBJECTIVE:To explore the standardized package of Metformin tablets to meet clinical needs. METHODS:Statis-tics was conducted for the utilization data of Metformin tablets in medical and health institutions from 6 cities of China;question-naires were designed to investigate and analyze the evaluation for the suitability of physicians,pharmacists and patients in the pre-scription,deployment and use links to Metformin tablets with different packaging loaded amount in Beijing and Haikou. RE-SULTS:For 0.5 g/tablet,the daily dose of 1.5 g accounted for the largest proportion (32.23%-69.91%) in 5 cities except for Chengdu. Totally 490 questionnaires about package suitability of Metformin tablets in outpatient department were sent out,includ-ing 478 valid questionnaires with effective rate of 97.5%. Results showed that packaging quantity with 4 weeks was considered as appropriate by physicians,pharmacists and patients in Beijing;however,packaging quantity with 1-2 week(s) was considered as appropriate by physicians,pharmacists and patients in Haikou;300-500 tablets of packaging quantity were preferred to be appropri-ate with the matching degree of automatic dispensing machines in both places. CONCLUSIONS:Considering the results in 2 plac-es,for 0.5 g/tablet,2 weeks is appropriate for the packaging loaded amount in outpatient department,that is 0.5 g×45 tablets/box;and 300-500 tablets/box is appropriate for inpatient pharmacies.

Objective To identify the pathogen of an acute epidemic gastroenteritis outbreak in newborn room. Methods Forty five samples were collected from 38 newborn patients at the peak of a diarrhea outbreak, which happened in a newborn room in Inner Mongolia Autonomous Region during December 2008 to February 2009. The presence of rotavirus antigen, Adeno-like virus antigen and Astrovirus antigen were detected by enzyme-linked immunosorbent assay (ELISA). The presence of Astrovirus RNA were detected by reverse transcriptase polymerase chain reaction (RT-PCR) with universal primer of Astrovirus. Thirteen samples positive for Astrovirus nucleic acid were analyzed by sequencing and phylogenetic tree. Four samples positive for both Astrovirus antigen and Astrovirus nucleic acid were observed by immune electron microscopy. Results Both rotavirus antigen and Adeno-like virus antigen were negative in 45 faecal samples. Thirty samples were positive for Astrovirus antigen when checked by ELISA, which resulted in a positive rate of 66.7%. Thirty-one samples were positive for Astrovirus RNA when check by RT-PCR, which resulted in a positive rate of 68.9%. The genotype results confirmed all patients were infected with genotype 1 Astrovirus. The gene sequences of thirteen samples were compared with reference strains of Astrovirus type 1 in GeneBank and the homology rate of nucleotide sequence was 90.9 %- 96.3 %. The homology rate of intra these thirteen sample was 94.7%-100.0%. Four positive samples were randomly selected and observed by immune electron microscopy and a large amount of Astrovirus particles were found in two of these samples. Conclusion Genotype 1 Astrovirus is the pathogen of this diarrhea outbreak in newborn.
