Objective To observe the effect of Chinese medicine of Gukang(GK) on bone mineral density(BMD) in osteoporosis rats.Methods Seventy-two female SD rats were randomized into 6 groups: pseudo-operation group,model group,nilestriol group(in the dose of 1mg/kg),and high-,middle-and low-dose GK groups(9.6,4.8 and 2.4 g?kg-1?d-1 respectively).Rat models of osteoporosis were induced by removal of bilateral ovaries.Three months after operation,the rats were given the corresponding medicine according the experimental design.After treatment for 3 months,in-vivo BMD as well as the in-vitro BMD in the isolated left femur and tibia was detected with dual energy X-ray bone densitometer.Results The in-vivo general BMD and lumbar BMD of the model group were decreased(P

Objective To study the effect of integrated tradition and western medicine on unstable angina.Methods Sixty-six patients with unstable angina were randomized into two groups:control group treated only with routine therapy(n=33) and experiment group treated with routine and jia jian luang gan jian therapy(n=33).The difference of EKG,symptoms and clinic comprehensive evaluation between before treatment and after-3-week-treatment were compared.Results The rate of symptoms and ECG improvement was higher in experiment group than control group(94% vs 73%;73% vs 45%).The difference of clinic comprehensive score between before treatment and after 3 weeks treatment was significantly higher in experiment group.Conclusion The treatment of integrated tradition and western medicine on patients with unstable angina is more effective.

OBJECTIVE:To analyze the utilization of drugs in children with ventricular septal defect(VSD) undergoing operation.METHODS:The medical orders of 120 VSD children patients in our hospital in 2005 were analyzed retrospectively.RESULTS:The per capita drug cost was(3 067.20? 325.04) yuan,accounting for 9.52% of the total medical cost.Circulatory system drugs and antibiotics were the chief categories.Leading the first 3 places in terms of DDDs were cefuroxime,vecuronium bromide and furosemide,respectively.CONCUSION:The drug cost for VSD children patients was relatively low and reasonable.

Objective To investigate the effects of seed sources and storage conditions on the seed germination rate of Valeriana officinalis. Methods The seeds of V. officinalis under different storage conditions were used as materials for germination test, and the germination rate was calculated and compared according to the results. Results The seed germination rate of valerians is varied with different sources. The seed germination rate of V. officinalis is higher than that of V. officinalis var. latifolia, and the seed germination rate of cultivated valeriana is much higher than that of the wild plant. The storage periods, storage temperature, and germination conditions also affect the germination rate. Conclusion To maintain the seed germination rate, the seed of V. officinalis should be stored in conditions with ventilation and at suitable low temperature. Lower temperature helps to prolong the seed life with relatively high germination rate. Valeriana seed should also be propagated at available temperature conditions in proper seasons.

In the treatment of facial paralysis in the acute stage and restoration stage by shallow needling technique and penetrating needling technique respectively, totally 106 cases, the effective rate is respectively 98.6% and 83.9%, indicating that the curative rate is high if early treatment is given.

Objective To investigate the role of PET-CT in evaluating the response to the treatment in patients with multiple myeloma.Methods 55 newly diagnosed multiple myeloma patients were collected.Patients were provided with 3 CTD chemotherapy,complete blood examination before and after treatment,parallel PET-CT,and measuring the spine,pelvis,rib SUVmax,each with an average of the SUVmax.The curative effect observated in SUV changes and disease were evaluated.Results In 24 patients after treatment,CR,SUV values were significantly decreased [(3.82±0.83) vs (2.05±0.49),t=9.045,P ＜ 0.001].11 cases of VGPR,SUV values were decreased [(4.77±1.13) vs (3.29±0.49),t =3.998,P =0.001].9 cases of PR,SUV values were slightly decreased [(5.36±0.47) vs (4.97±0.40),t =1.886,P ＞ 0.05],in 8 cases of SD,the SUV values had no obvious change [(6.40±0.96) vs (5.63±0.69),t =1.819,P ＞ 0.05],in 3 cases of disease progression we had higher SUV values from the previous [(6.57±0.72) vs (7.53±4.69),t =-0.353,P ＞ 0.05].CR of 24 cases were followed up for 12 months,SUV values were still high in patients after treatment of the short progression-free survival (PFS) (Some patients only lasted 4 months).Conclusion PET-CT has important value in the evaluation of therapeutic effect of multiple myeloma,it helps to determine the early clinical efficacy,and to plan individualized treatment.

Objective To explore the effects of homocysteine (Hcy) on neural stem cell (NSC) proliferation and the mRNA expression level of Notch1 and Hes1 related Notch signaling pathway from neonatal rats in vitro. Methods NSCs from neonatal rats were cultured by serum-free culture method in vitro. Cells were divided into four groups: control group (Hcy-C), low dose Hcy (Hcy-L) group, middle dose Hcy (Hcy-M) group and high dose Hcy (Hcy-H) group. NSCs were iden- tified by immunofluorescent staining using the antibodies against Nestin, β-tubulin Ⅲ and GFAP. The proliferation ability of NSCs was detected by MTT. The mRNA expressions of Notch1 and Hes1 were detected by Real-time PCR. Results In the serum free suspension medium, neurospheres that consisted of a great number of nestin-positive cells were found. β-tu- bulin Ⅲ positive neurons and GFAP positive astrocytes were detected by immunofluorescence staining on the 6 th day of cell induction. MTT assay showed that the cell viability was significantly lower in three Hcy treatment groups than those of con- trol group (P ＜ 0.05). And the effect of concentration-dependent was observed. The results of RT-PCR showed that mRNA expression of Hes1 was significantly lower in three Hcy treatment groups than that in control group (P ＜ 0.05). The mRNA ex- pression of Notch1 was significantly lower in Hcy-H group than that of other three groups (P ＜ 0.05). The mRNA expression of Notch1 was significantly lower in Hcy-M group than that of Hcy-L group and control group (P ＜ 0.05). Conclusion Hcy could inhibit the proliferation of NSCs by down-regulating mRNA expression levels of Notch1 and Hes1 genes related to Notch signal pathway.

Objective To explore the correlation of single nucleotide polymorphism ( SNP ) in Nrf2 gene with acute mountain sickness ( AMS) among Han populations in China .Methods As a nested case-control study , 603 Chinese Han young men who had been quickly exposed to 3700 m were adopted and divided into case group and control group ( 369 vs 234,respectively) by Lake Louise Self-assessment Scoring System(LLSS).The Sequenom Mass Array system was used to detect the SNPs of rs10497511 and rs2364722 in Nrf2 gene.Results Alleles of rs10497511 and rs2364722 were respec-tively detected in both case and control groups , which were T-C and A-G.Statistically significant difference was not found in allele frequencies ( P>0.05 ) .Further analysis showed that there was still no significant difference between the codomi -nant, dominant and recessive genotype models (P>0.05).Conclusion rs10497511 and rs2364722 of Nrf2 gene may not be related to susceptibility to AMS in Chinese Han populations .

Objective The purpose of this study was to investigate the correlation of high sensitivity C-reactive protein (hsCRP) and fibrinogen with carotid artery arteriosclerosis of patients with cerebral infarction. Methods One hundred and thirteen patients with cerebral infarction were assigned as study group, and 102 healthy persons as control group. The levels of serum hsCRP and Fib in the two groups were measured. The carotid artery arteriosclerosis and carotid intimal-medial thickness (IMT) were examined by color Doppler and B-ultrasound. Results The value of IMT between study group and control group was statistically significant. The positive rates of carotid artery arteriosclerosis plaque and vulnerable plaque in study group were significantly higher than those in control group (all<0.05) . The level of serum hsCRP was significantly higher in study group than that of control ( <0.05) . The level of serum Fib between study group and control group was not statistically significant ( >0.05) . Conclusion The level of hsCRP was closely related to the degree of carotid artery arteriosclerosis and the occurrence and development of cerebral infarction. But the level of Fib was not closely related to the degree of carotid artery arteriosclerosis.
