OBJECTIVE:To research the correlation between per capita disposable income,investment of pharmaceutical advertisement,people’s healthy level,pharmaceutical price and the demand of drugs in China METHODS:Based on the economical theory,the methods of the econometrics and the Eviews were adopted to establish the model of demand function RESULTS & CONCLUSION:Under the background of the non-full competition,the improvement of people’s living conditions can lead to the demand of drugs The changes of drug price have little influence on the demand of drugs

The coronary collateral circulation is an alternative source of blood supply to the myocardium jeopardized by failure of the original vessel to provide adequate flow. Angiogenesis growth factors induce angiogenesis to promote collateral circulation, been demonstrated in a number of different animal test and phase Ⅰ clinical experience to induce collateralization in the ischemic area and improve cardiac function. Although there are several unsolved questions, the pharmacologic use of angiogenesis growth factors will represent a viable therapeutic alternative for the patients with ischemic heart disease.

By generalizing the integrity crisis of college students,the article analyzes the causes of this phenomenon,and proposes a series of measures aiming at strengthening integrity education,establishing the favorable environment,completing the mechanism of rewards and punishments and building the credit system,in the hope of securing the deepening and full completion of good-faith education at college,both ideologically and systematically.

AIM: To establish the quality standard of Huoxuejiangu Capsules (Radix Salviae Miltiorrhizae, Radix Paeoniae Rubra, Radix Astragali seu Hedysari, Rhizoma Corydalis, Fructus Psoraleae, etc.). METHODS: Radix Astragali, Rhizoma Corydalis, Radix Paeoniae Rubra, Fructus Psoraleae were identified by TLC. The content of tanshinone Ⅱ A was determined by HPLC. RESULTS: Radix Astragali, Rhizoma Corydalis, Radix Paeoniae Rubra, Fructus Psoraleae could be dtected by TLC. Tanshinone Ⅱ A showed a good linear relationship at the range of 0.106～2.12?g, r =0.9996. The average recovery was 98.6%, and RSD was 1.48%. CONCLUSION: The method established is simple, feasible and reproducible. This study provided a method for quality control of Huoxuejiangu Capsules.

AlM:To determine the relations between the changes of vascular endothelial growth factor ( VEGF ) concentration in plasma, aqueous humor and vitreous of patients with diabetic retinopathy ( DR ) and proliferative diabetic retinopathy ( PDR) , as well as to find if the condition of metabolism control of patients with DR may affect the VEGF level.
METHODS: Double antibody sandwich enzyme-linked immunosorbent assay was used to measure the levels of VEGF concentration in plasma of non-diabetic retinopathy ( NDR ) patients group, background diabetic retinopathy ( BDR ) patients group, and proliferative diabetic retinopathy ( PDR) patients group. The levels of HbAlc in plasma of patients in above three groups were measured at the same time. The VEGF concentration in aqueous humor, vitreous of PDR patients group and normal group was also measured for further comprehensive analysis. Human VEGF immunoassay Quantikine with high sensibility and quality was imported from R&D Co. LTD. , USA.
RESULTS: There was an increasing tendency in the VEGF concentration in aqueous humor of PDR patients group. There was no statistically significant difference as it was compared with normal group (P>0. 05). The VEGF concentration in vitreous of PDR patients group was obviously increased, there was significant difference as it was compared with normal group (P<0. 01). lt showed an increasing tendency of VEGF concentration in turn in plasma, aqueous humor and vitreous of the 3 PDR patients selves. lt showed that there was significant difference among VEGF concentration in plasma, aqueous humor and vitreous of all the PDR patients (P<0. 01). ln normal group there was no significant difference among VEGF concentration in plasma, aqueous humor and vitreous ( P > 0. 05 ). ln normal group the VEGF concentration in plasma was the highest, but in PDR patients group the VEGF concentration in vitreous was the highest.
CONCLUSlON: The significantly increased VEGF concentration in eyes, especially in vitreous of PDR patients may play an important role in development and deterioration of DR. lt was clear that VEGF played its normal biological functions mainly in plasma in normal human. ln severe DR patients, abnormal high may come from ischemic and VEGF concentration in vitreous suggested that it hypoxic retina and there was a tendency to diffuse towards the front of eyes.

OBJECTIVE:To evaluate the status quo and the developmental trend of the application of antidepressant drugs in our hospital.METHODS:The antidepressant drugs in our hospital during2002～2004were analyzed retrospectively in terms of drug varieties,consumption quantity,consumption sum,DDDs etc.RESULTS:The consumption sum of the antidepressant drugs increased year by year,which stood at667.41,802.47and995.02(RMB:ten thousand yuan),respectively in the3years.CONCLUSION:Fluoxetine dominates the first place in terms of clinical application of antidepressants.Furthermore,the application of new type antidepresants has been on the rise.

Objective To investigate the relationship between smoking and the occurrence of pulmonary tuberculosis among type 2 diabetics(DM-PTB).Methods A hospital-based case-control study was carried out at three hospitals in Tianjin from 2001 to 2002.87 cases of newly-diagnosed pulmonary tuberculosis with type 2 diabetes mellitus and 129 controls by frequency-matched by gander and age were recruited and interviewed.Univariate and multivariate unconditional logistic regression analysis was conducted.The adjusted odds ratio(OR) and 95% confidence interval(CI) were estimated.Results Higher smoking index(OR=1.399,95%CI=1.098～1.782)?beginning smoking at younger(OR=2.028,95%CI=1.076～3.821)?large consumption of cigarets per day(OR=1.349,95%CI=1.087～1.674)?no smoking cessation after diabetes diagnosis(OR=5.327,95%CI=1.703～16.661) were significantly associated with DM-PTB after adjusted for other risk factors.Among female diabetics large consumption of cigarets per day? beginning smoking at younger higher smoking index were generally associated with increased risk of pulmonary tuberculosis;while without smoking cessation after diabetes diagnosis might be risk factor among the male;higher smoking index might increase the risk of pulmonary tuberculosis among younger(youger than 60y) diabetics.Conclusion Smoking control or cessation among type 2 diabetics might decrease the risk of pulmonary tuberculosis.

Nonglomerular synapses in the neuropil of the substantia gelatinosa of adult ratspinal trigeminal nucleus were subjected to electron microscopic examination. Nonglomerular synapses in the substantia gelatinosa were associated with four main types of axonal terminals. On the basis of vesicle shapes, these were classified as round vesicle, elongate vesicle, pleomorphie vesicle, and dense cored vesicle terminals. The category of round vesicle terminals could be subdivided into large round vesicle terminals and small round vesicle terminals according to their different size of synaptic vesicles. Nonglomerular synapses included four types, i. e. axodendritic, axo-axonic, dendro-dendritic and dendro-axonic synapses. Of these, the majority of synapses were axodendritie. The functional significance of the classification of these synapses and their axonal terminals had been discussed.

Large dense core vesicle in the trigeminal subnucleus caudalis of the rat has been observed electron microscopically. It is fixed in glutaraldehyde-osmium tetroxide following removal of the skin of the vibrissae areas. The findings of the present study are: 1.Morphological evidence for exocytosis of large dense core vesicle from non-synaptic sites of the axonal terminal has been presented.2. The large coated vesicles equipped with central densities derived from the invagination of the plasma membrane. These observations suggest that membrane recycling occur at location in the terminal via these coated vesicles.3.Some large dense core vesicles may also form the tubular structures which may represent smooth endoplasmic reticulum containing dense material. This study supports the hypothesis that release of the transmitter of the great dense core vesicles occur at nonsynaptic sites by exocytosis.
