Objective To investigate the correlation between HDL-C/TG ratio and cardiovascular risk in elderly patients with hypertension, in order to set up an evaluation criterion which may objectively assess the cardiovascular risk in elderly population. Methods A survey was carried out among 2011 subjects aged 60 or over, who received health examination in the General Hospital of PLA in May 2008. Hypertension was diagnosed by using the definition recommended by WHO/ISH. The subjects were divided into 4 groups (male hypertesion group, male control group, female hypertension group and female control group) according to their gender and with or without hypertension. The parameters of hematology (systolic pressure, diastolic pressure, pulse pressure and mean arterial pressure) and the indicators of lipidemia [total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C)] were measured, and HDL-C/TG ratio was calculated. Logistic regression analysis was used to analyze the correlation between the indicators of lipidemia and cardiovascular risk. Results In both male and female hypertension groups, systolic pressure, diastolic pressure, pulse pressure and mean arterial pressure showed significant differences compared with those of the control groups gender-wise (P0.05). Other indicators of lipidemia showed no significant differences between hypertension group and control group. Logistic regression analysis showed that HDL-C/TG ratio was significantly correlated to the cardiovascular risk (P

Neonatal hypoglycemia is a common metabolic problem. The definition and clinical management of neonatal hypoglycemia remains controversial. The concerned reasons are mainly as follows:the course of a physiological decrease and recovery in the level of blood glucose is usually existed in newborn infants after birth;asymptomatic hypoglycemia(many newborn infants' blood glucose level is very low but without any clinical signs or symptoms);and the lack of the complete comprehension for the relationship between neonatal hypoglycemia and the long-term neurologic prognosis. The review describes the etiology,definition and clinical management of hypoglycemia in newborn infants.

Allogeneic hematopoietic stem cell transplantation is the only measure which can cure multiple myeloma,but the high mortality rate related with it limited its use.Autologous hematopoietic stem cell transplantation(Auto-HSCT) has made a great contribution at improving the patients' quality of life and prolonging the survival.In recent years,the application of new drugs and new chemotherapy regimen consisted of traditional chemotherapy and new drugs further enhance the curative effect.

Conclusion: Self concept was significantly correlated with mental health in middle school students.

BACKGROUND: Anti-virus therapy is not suitable for the patients who have asymptomatic human immunodeficiency virus (HIV); otherwise, it is significant for early intervention of Chinese herbs to cure asymptomatic HIV.OBJECTIVE: To observe the interventional effects of fuzheng paidu pian on level of CD4+T lymphocytes and changes of plasma viral vector expression in early phase of asymptomatic HIV infection.DESIGN : Observational contrast study.SETTING: Institute of Acquired Immunodeficiency Syndrome (AIDS), Henan College of Traditional Chinese Medicine.PARTICIPANTS: A total of 69 asymptomatic HIV patients, who were infected by paid blood, were randomly selected from some countryside in November 2005. There were 39 males and 30 females. Their ages ranged from 30 to 61 years and the mean age was (43±8) years, and the mean course was (13±3) years. Inclusion criteria: ① coincident with diagnostic criteria of asymptomatic HIV infection published by National AIDS committee (modified in 2005); ②from 18 to 65 years old; ③ 200/mm3 ≤CD4+T lymphocyte count ＜ 600/mm3; ④ Patients did not treat with antiviral and other drugs; ⑤ All patients provided the confirmed consent. Exclusion criteria: ① severe liver and renal malfunction,combining with cardio-cerebral vascular disease and severe primary diseases of lung and hematopoietic system,mental diseases; ② primary immunodeficiency, secondary immunodeficiency induced by hormone and radiation therapy, hematologic disease; ③ pregnant or lactational women. Another 25 asymptomatic HIV patients were randomly selected.and regarded as the blank group. Inclusion and exclusion criteria were as the same as those in the treatment group.METHODS: Patients in the treatment group were treated with fuzheng paidu pian (consisting of huangqi, raw baizhu,fangfeng, baihuashe shecao, ganca o, etc.; Aolinte Pharmaceutical Factory of Henan Institute of Traditional Chinese Medicine; batch number: 050601) by using warm boiled water, 5 tablets once (eqUal to 6.6 g raw materials) for three times a day. Three months were regarded as a course and the treatment was performed four courses in total. Patients in the blank group were not treated with any drugs.MAIN OUTCOME MEASURES: ① Values of CD4+, CD8+ and CD4+/CD8+ in the treatment group before and after treatment;CD4+T lymphocyte count in the blank group after 6 months; ② Viral vector was detected by using reverse transcription polymerase chain reaction (RT-PCT) in the treatment group.RESULTS: All 69 patients in the treatment group and 25 patients in the blank group were involved in the final analysis. ①CD4+ value was decreased in the blank group after 6 months, and there was significant difference before and after 6 months based on α =0.05 level (P ＜ 0.05).However, CD4+ value was increased in the treatment group. ② Viral vector was randomly detected from 23 patients in the treatment group. As compared with before treatment, plasma viral vector was decreased in 9 patients at 6 months after treatment and in 12 patients at 1 year after treatment. The effective rate was 91.30%.CONCLUSION: Fuzheng paidu pian can improve immunological function of asymptomatic HIV patients and decrease viral vector in some cases during early interventional period.

Objective　To study the relationship between the changes of cytosine，thymine，guanine（CTG）repeat numbers and brain stem BAEP,SEP and VEP in patients with myotonic dystrophy（DM） and their family members.Methods　The repeat numbers of CTG，BAEP， SEP and VEP of DM gene were determined by PCR amplification and DNA hybridization in 5 patients with DM and 16 members from 3 families.Results　The repeat numbers of CTG in 10 normal persons were 30，BAEP，SEP and VEP were normal.The repeat numbers of CTG in 5 patients with DM were over 85，two cases of them were over 1605，they were significantly higher than the normal persons.4 cases in 16 family members were normal,CTG repeat numbers of 12 cases were over normal genes,CTG repeat numbers were related to clinical symptom, BAEP，SEP and VEP.Conclusion　The gene diagnosis of DM was found to be consistent with its clinical symptom，the changes of BAEP，SEP and VEP.
