Vitamin D has a wide range of biochemical effects. Insufficiency/ deficiency of vitamin D increases the risk of insulin resistance by ways of inflammation,adipocytokines,oxidative stress and mitochondria function,it could lead to metabolic disorder of glucose and lipid,which closely relates to the incidence and development of obesity and metabolic syndrome on children. This paper presents the relationship between vitamin D with obesity and metabolic syndrome on children,states the possible mechanisms of regulation of glucose/ lipid metabolism and insulin resistance by vitamin D.

The paper analyzed the necessity of the testing items for blood transfusion compatibility.By means of a comprehensive evaluation of the testing requirements of blood transfusion labs,and a basis on characteristics of blood transfusion profession and technical specifications in clinical transfusion,the paper probed into building appropriate lab examination techniques in terms of ABO blood type testing item,RhD blood type testing item and screening test,and cross-matching testing items,for the purpose of achieving the safety and effectiveness of clinical blood use.

Calcium channels express abnormally in glioma,and play a key role in the physiological functions of glioma such as tumorigenesis,proliferation,metastasis and angiogenesis. Researches show that low or high expressions of different types of calcium channels have influence on the development of glioma and cell-cycle redistribution. Such calcium channels may represent new targets in treating glioma,which provide new ideas for controlling glioma.

Objective To investigate the clinical status of massive transfusion in elderly patients in general hospital in order to improve the clinical use of blood and ensure the security of blood transfusion in elderly patients.Methods 100 patients who required massive transfusion were divided into 2 groups:elderly group (patients aged 60 years and over,n=32) and non-elderly group (patients aged under 60 years,n=68).Clinical blood transfusion indications in all patients met the Technical Criterion of Clinical Blood Transfusion issued by Ministry of Health of the People's Republic of China in 2000.Clinical data were analyzed and compared between the two groups.Results Elderly patients with massive transfusion were mainly in department of surgery,including department of orthopedics,general surgery,hepatobiliary surgery,cardiac surgery and urology surgery and gastroenterology,and the mean age of patients in these departments was 71.5 years,69.9 years,72.0 years,66.0 years,65.5 years,70.8 years respectively,accounting for 50.0％,70.0％,20.0％,75.0％,20.0％ and 66.7％ in all patients who required massive blood transfusion respectively.The mean blood transfusion volumes were higher in patients in department of gastroenterology,general surgery,hepatobiliary surgery and orthopedic,in which the mean units of red blood cell components transfusion were 14.0 U,7.0 U,5.2 U and 4.1U respectively,the mean units of plasma components transfusion were 23.3 U,8.4 U,8.0 U,0.5 U respectively,and the mean uint of platelet components transfusion was 1.6 U in hepatobiliary surgery.Conclusions The risk of blood transfusion is higher in the elderly than in the non elderly.We should select the effective blood components reasonablely,reduce the unnecessary blood transfusion and decrease the dependence on plasma transfusion to avoid the transfusion overload and adverse reactions.

Objective:To establish an HPLC method for the simultaneous determination of olmesartan medoxomile, amlodipine be-sylate and hydrochlorothiazide in compound olmesartan medoxomile tablets. Methods:The desired chromatographic separation was a-chieved on a Phenomenex C18 (250 mm × 4. 6 mm, 5μm) column. With gradient elution, the optimized mobile phase consisted of ace-tonitrile as solvent A, and 50 mmol·L-1 potassium dihydrogen phosphate buffer (pH 3. 0, containing 0. 05% triethylamine) as sol-vent B. The flow rate was set at 1. 0 ml·min-1 , the column temperature was 30 ℃, the UV detection was carried out at 236 nm and the sample size was 20μl. Results:The compounds were separated well, the linearity between the peak area and the concentration was observed within the range of 4. 0-80. 0 mg·L-1(r=0. 999 9)for olmesartan medoxomile, 1. 0-20. 0 mg·L-1(r=0. 999 9)for amlo-dipine besylate and 1. 25-25. 0 mg·L-1(r=0. 999 9)for hydrochlorothiazide. The average recovery of olmesartan medoxomile, amlo-dipine besylate and hydrochlorothiazide was 99. 1%(RSD=1. 31%, n=9), 100. 3%(RSD=1. 21%, n=9) and 100. 2%(RSD=1. 06%, n=9), respectively. Conclusion:The method is specific and stable in the determination of olmesartan medoxomile, amlo-dipine besylate and hydrochlorothiazide in the tablets.

Ojective The improve laparoscopic treatment of inguinal hernia in children. Methods 40 children aged from 2 to 14 years were treated by single port laparoscopic surgery for inguinal hernia between January 1999 and December 2000. Twenty four children manifested a right inguinal hernia, 12 a left hernia, and four cases a bilateral hernia. All the patients were treated by purse-string suture around the internal ring under laparoscopy. Results The duration of operation were from 10 to 30 minutes. There was no intra-or postsurgical complication. Conclusions The single port laparoscopic surgery is a simple, conveninet, quick and safe and minimal invasive procedure for the treatment of inguinal hernia in children.

Zishen Tiaochong therapy can improve the function of corpus luteum.The function of corpus luteum has close correlation with vasculogenesis in which the bone marrow-derived endothelial progenitor cells(EPCs)were involved.This implies the Zishen Tiaochong therapy may be correlative to vasculogenesis in corpus luteum via mobilizing bone marrow-derived EPCs.In this paper,based on the TCM theory of 'kidney(Shen) storing essence,producing bone marrow,controlling reproduction',we review the topic of Zishen Tiaochong therapy perfects the function of corpus luteum combined the new mechanisms of research advances in vasculogenesis.The possible mechanisms of promoting vasculogenesis in corpus luteum by Zishen Tiaochong therapy were discussed and analyzed.

Objective Study the common symptoms of sub-healthy people. Methods Study the 59 symptoms of the 1 828 cases of sub-healthy people that the study of DME Research on TCM Syndrome of Sub-health State had collected. Select the symptoms by analysis of percentage, mean, correlation and discriminance. Finally, find out the symptomatic characters of the sub-healthy people by the data mining method of decision tree. Result There were 26 variables selected from the 56 symptoms. The result of decision tree showed that low quality of sleep, fatigue, dry in throat, acid and distend in eyes, ache, emptiness in heart had greater relations with sub-health. Conclusion Low quality of sleep, fatigue, dry in throat, acid and distend in eyes, ache, emptiness in heart are the symptoms that have greater relations with sub-health.

Objective To establish a real-time fluorescent quantitative RT-PCR for detecting SARS-Coronavirus (CoV) mRNA in gargling liquid and serum of SARS patients.Methods The assay is based on simplified nested fluorescent RT-PCR. Total RNA was extracted from gargling liquid and serum by using high performance system and reverse-transcription by antisense primer.The specific TaqMan probe was designed according to the published DNA sequence of SARS-CoV polymerase and labeled with FAM and TAMRA. Standard curves for SARS-CoV quantification were prepared with serial dilutions of the recombinant plasmid.Results The method is highly sensitive and specific. The sensitivity of assay was 1?105 copies/L. The positive rate of SARS-CoV mRNA in the gargling liquid of patients was 65.0% (26/40) and 11.5% (6/52) in suspected patients, respectively. SARS-CoV mRNA was not detectable in the gargling liquid from 40 healthy individuals. The positive rate of SARS-CoV mRNA in the serum of SARS patients was 25.6% (10/39). PCR amplification products of 6 suspected patients with SARS-CoV mRNA were confirmed by sequencing and the sequence data were consistent with that of BJ01 AY278488.Conclusions Real-time fluorescent quantitative RT-PCR should be a rapid, specific tool for early diagnosis of SARS-CoV infection.
