Diabetic Osteoporosis is a general metabolic bone disease having fracture tendency because of osteopenia in unit volume,microstructural changes of bone tissue,decreased bone strength and increased friability,which is one of important complications of diabetes mellitus in skeletal system.Studies on bone involvement in patients with diabetes mellitus have generated conflicting results,largely because of the pathogenetic complexity of the condition.There are many factors,including advantageous and disadvantageous factors,influence the probability of osteoporotic fractures in diabetics.Adequate glycemic control,and calcium and vitamin D intakes,and the prevention and treatment of diabetic complications are key elements in the elimination of osteoporosis in diabetes mellitus.Patients with osteoporosis and diabetes should be offered the same pharmacological treatments as non-diabetics.

Spleen-yin theory was the innovation of doctors in Ming Dynasty for Piwei theory of Dongyuan based on the inheritance of nourishing yin theory of Danxi. But because of rise of stomach yin theory, spleen yin theory was ignored gradually. This article revealed the neutralizing therapeutic conception contained in this theory, which was hoped to be applyed into medical practice and to be deepened furtherly.

Objective To compare the clinical effect of intraosseous versus traditional infusion in critical pediatric patients under resuscitation.Methods 56 critical pediatric patients under resuscitation,who were difficult to establish a venous access,were divided into two groups:intraosseous infusion group (IOI group)and traditional group.The clinical characteristics,lab tests,clinical efficacy and complications of all patients were recorded in detail. Results The general characteristics of two groups were comparable.The mean operation time to establish an emergency infusion access in the IOI group was (1.01 ±0.53)min,which was significantly shorter than (8.97 ±2.36)min of the traditional group(t =4.856,P <0.01).The IOI group had a greater efficacy over the traditional group (50.0% vs 36.7%),in the IOI group,the patients showed obvious positive effect and less patients had no efficacy(χ2 =18.476, P <0.05 ).In addition,lower complication rate and mortality were observed in the IOI group.Conclusion For critical pediatric patients under resuscitation whose intravascular access cannot be achieved through peripheral venous,intraosseous infusion is prior to traditional infusion.

Aim Vascular endothelial cell growth inhibitor(VEGI) is a recently discovered novel member of the TNF superfamily,which is expressed predominantly in endothelial cells.As an endothelial cell-specific negative regulator of angiogenesis,the relationship between structure and function of VEGI is not understood at present.Methods In order to explore the functional key amino acids of VEGI,four mutants of VEGI(E45→R,G47→A,Y111→F,Y111→T) were construced by site-directed mutagenesis,and recombinant proteins were generated from E.coli.Four mutant proteins behaved similar to the wild type VEGI in various physico-chemical assays.The proliferation of HUVEC and chick choriallantic membrane assay were performed to study the activity of four mutants.Results The mutant E45→R significantly decreased the biological activity,and the mutant G47→A caused a slight drop on activity,but the mutants Y111→F,Y111→T almost completely abolished biological activity.Conclusion It suggests that Y111 is an important residue in biological activity,which may play a direct role in receptor recognition.Moreover,the tyrosine ring and hydroxy group of the amino acid are important determinant of biological activity.Additionally,E45 also plays an important role in biological activity of VEGI.

Objective To evaluate the correlation between the Waters classification based on shoulder CT or MRI scan and passive shoulder external rotational angle before operation in the glenohumeral joint deformity caused by shoulder internal rotational contracture secondary brachial plexus birth palsy.Methods 33 patients suffered the shoulder internal rotational contracture secondary brachial plexus birth palsy (Tassin classification Ⅱ 19, Ⅲ 13, Ⅳ 1) including 12 girls and 21 boys, ranging from 10 months to 16 years old with an average of 4.5 years old, underwent either CT or MR examination in shoulder joint. The retroversion of the glenoid (glenoscapular angle) and the ratio of humeral head posterior subluxation were measured on the CT or MRI images according to the method described by Friedman. The deformity of glenohumeral joint was classificated according to the Waters criteria, while the passive shoulder external rotational angle was measured at neutral position in involved shoulder joint. The correlation between the external rotation and the deformity was analysed. Results 33 cases with shoulder internal rotational contracture secondary brachial plexus birth palsy were evaluated according to the Waters criteria. 4 cases were classified as typeⅠdeformity, 4 cases as typeⅡ, 7 cases as type Ⅲ, 6 cases as type Ⅳ; 5 cases as typeⅤ; 7 case as type Ⅵ. The type of glenohumeral deformity was significantly associated with the limited range of passive external rotation of the shoulder joint. Conclusion The Waters classification of the glenohumeral deformity according to the Waters criteria can accurately demonstrated the deformity of the glenohumeral joint caused by shoulder internal rotational contracture secondary to brachial plexus birth palsy.

One hepatitis C virus(HCV) cDNA fragment, 534bp in length and designated as Q534, was obtained by means of PCR amplification with self-designed oligonucleotide primers. Q534 was doned into Hinc II site of pUC18 and the- recombinant plasmid pQ534 was then selected from the bacterial transformants. The sequence data indicated the Q534 was a cDNA fragment of HCV core gene, and located in HCV genome from positions 320 to 853 in correspondence with Chiron's prototype sequence. The homologies between Q534 and the prototype at the levels of nucleotides and amino adds were 90.9% and 97.6%, respectively. The homologies of Q534 with Japanese HCV-J and HCV-BK strains were 96.8% and 97.0% at the nucleotide level, and 98.2% and 98.8% at the amino add level. Compared with the corresponding sequences of other HCV isolates, this Chinese HCV isolate we obtained in the present study belongs to HCV group II .

Hepatitis C virus (HCV) is a major causative agent for sporadic and post-transfusion hepatitis, which frequently progresses into chronic hepatitis, liver cirrhosis and hepatocellular carcinoma. In order to clarify the genomic variations and the structural characteristics of Chinese HCV isolate, we extracted HCV genomic RNA from plasma specimens of Chinese hepatitis C (HC) patients, reverse-transcribed to HCV cDNA with random primers and constructed successfully an HCV cDNA R gt11 library of Chinese type. Two positive clones (Q349 and Q653) were selected by immunoscreening from the library and subcloned into plasmid vector pUC18. Sequence analyses indicated that Q349 was derived from core region (positions 554-902) of HCV genome while Q653 was from NS3 region (positions 4175-4827) corresponding with the prototype HCV nucleotide sequence. The homologies of Q349 and Q653 with the equivalent sequences of HCV prototype were 86.8% and 80.2% at the nucleotide level, and 97.3% and 93.1% at the amino acid level, respectively. It was found that Chinese HCV clones had higher homologies with Japanese HCV isolates, and should belong to HCV group II. Specificity test proved that the encoded peptides of the 2 Chinese HCV cDNA clones reacted specifically with sera from HC patients and had no reaction with sera from healthy individuals. More importantly, clone Q653 showed higher positive reaction rates with Chinese HC sera (95.8%) than those with Japanese ones (85.7%), which strongly suggests that the sequences from Chinese HCV genome (especially from NS regions) would be more suitable for primer designing or peptide synthesis for the use in the detection of HCV infection among Chinese people.
