Objective To find out about the use of anti-infectious agents by tumor outpatients of the hospital. Methods A survey was conducted on 1 011 prescriptions for anti-infectious agents written out in the hospital from October to December of 2003 and an analysis was made of the structure and rationality of their use by means of drug utilization studies. Results The utilization rate of anti-infectious agents was 8.35% , accounting for 1.09% of the total sum of money for the prescriptions. The kinds of anti-infectious agents used were mostly cephalosporins and quinolones. The utilization rate of agents of compatibility was 4.44%. The drug utilization index of some chemicals was close to 1.00, accounting for about 44.44% . Conclusion There is no widespread abuse of anti-infectious agents by the outpatients of the hospital and the utilization rates of anti-infectious agents and agents of compatibility are low. Still, there are some problems in the use and compatibility of certain agents and the rationality of their use is to be questioned. The use of anti-infectious agents should be planned in a scientific way and in line with the economic condition of the patients.

During the last decade a lot of new learning about asthma was arisen along with the development of modern immunology and molecular biology,and asthma had been one hotspot in the studies of molecular biological and administer medical field.One of the new viewpoints was that airway neurogenic inflammation took important role in asthma development.For years scholars had suspected that airborne pollutants had an synergistic effect on the attack of asthma and could cause asthma attack,but they did not know the molecular mechanism.In 1991 Denish scholar Nielsen GD advanced a new hypothesis that airway irritation was mediated by capsaicin receptor.The pathological process included a molecular chain of message transfer as air pollutants_capsaicin receptor_Ca2+_substance P_neurokinin receptor.Airway neurogenic inflammation was the result of activation of the receptors.In 1997 American scholar Caterina MJ and his colleagues successfully obtained the cloned capsaicin receptor in expressing cells,this will make Nielsen GD's hypothesis living.

Objective To find out nutrient support drug utilization in cancer patients in our hospital. Methods An analysis was made by means of drug utilization research into the structure and rationality of nutrient support drug utilization in our hospital through an investigation into the detailed records of the dispensary from 1999 to 2002 and into 1 014 medical records from 2002. Results The variety, quantity, and cost of nutrient support drug utilization in the four years rose respectively by 58.82%, 71.66% and 28.16%. 49.30% of the cancer patients whose medical records were surveyed used such drugs. The quantity and person time ratio of PN and EN drug utilization was respectively 14∶1 and 13∶1, with malnourished patients accounting for 19.80%. Of the PN drugs whose DDD value could be determined, most had a DUI value that was greater than 1 whereas most of the EN drugs had a DUI value which was smaller than 1. Conclusion The variety, quantity, and cost of nutrient support drug utilization in the four years rose rapidly. The quantity and person time of PN drug utilization were much higher than those of EN drug utilization. Doubts could be cast in the handling of indications for nutrient support drug utilization in some patients and the doses of some nutrient support drugs prescribed were not so rational. Further explorations need to be made into the rational application of nutrient support treatment.

Objective Through the optical microscopic observation to investigate the pathological influence of topical oxygen therapy on wounds of rats' muscles in hot and humid environment. Method The rat traumatic models were established. Twenty-four rats were randomly divided into four groups, including normal envi-ronment comparison group (NEC group, n=6), normal environment oxygen therapy group (NEO group, n=6). hot and humid environment comparison group (HHE group, n=6), hot and humid environment oxygen therapy group (HHO group, n=6).Then all rats were sampled to observe the changes of rats' muscle under optical microscope. Results Pathologic histology of muscle cells were obviously changed in HHE group. In these rats. disorganized myofibrillae with some loss of myofilaments. The damage of the muscle fibers in HHO group were better than that in HHE group. The damage of muscle ceils in NEC group were slighter than that in HHE group, the muscle of rats in NEO group are all normal. Conclusion In hot and humid en-vironment pathologic histology changes of wounds were serious, topical oxygen therapy could relieve muscle tissue ultrastructures change.

Objective To study the mechanism of the protective effect of lycium barbarum polysaccharide on light aging resistance rats by using the metabolic profile and metabolic target analysis technique.Methods Ultraviolet irradiation induced Wistar rats were induced to produce skin photo aging model and 24 rats were randomly divided into three groups, including control goup, model group, Lycium barbarum polysaccharide group (LBP). After modeling for 24 hours, LBP group was conducted with Lycium barbarum polysaccharide solution of 10 mg/kg. Control group and model group were given same volume of stroke-physiological saline solution for 14 days. The biochemical indexes such as rat serum antioxidant activity of related substances and MDA were measured in model group and drug group; the urine metabolomics study was also investigated for the mechanism of lycium barbarum polysaccharide against light aging band.Results Compared with the model group, the LBP group rats total superoxide dismutase activity (301.51 ± 42.56 U/mgvs.93.41 ± 56.31 U/mg), hydroxyproline (8.91 ± 5.78μg/mgvs.4.74 ± 1.54μg/mg) content significantly increased (P<0.05), but the malondialdehyde (8.54 ± 6.41 nmol/mgvs.21.31 ± 6.58 nmol/mg) decreased without any statistics difference (P<0.05). The urine metabonomics results showed that LBP could regulate the skin photoaging of multiple metabolic pathways and key metabolic enzymes in the process, such as peanut four acid, tyrosine, taurine, citric acid and hippuric acid, L-cysteine, inositol, threonine etc.Conclusions In the process of skin photoaging in rats, multiple metabolic pathways in vivo were disordered, and Lycium barbarum polysaccharide could play a protective role by regulating the key metabolic enzymes in the network.

Objective To examine the expressions of AQP1 and VEGF in human hepatitis B associated hepatocellular c arcinoma and to investigate its relationship with the occurrence and development of hepatocellularcarcinoma. Methods AQP1 and VEGF expressionsin the cancer tissues and AQP1 and VEGF levels in the serum were detected in 62 cases of hepatocellula carcinomaby immunohistochemistry and ELISA , respectively. Results The expressions of AQP1 and VEGF in the liver cancers were significantly higher than in the normal tissues (P<0.01). The higher expression was related to pathologic type,degrees of differentiation and lymph node metastasis, but not related to sex, age and TNM stages. In the serum of liver cancer, the concentrations of AQP1 and VEGF were significantly higher than those in the control group. Conclusion High expressions of AQP1 and VEGF in the patients with liver cancer may be correlated to the occurrence and development of liver cancer. Plasma levels ofAQP1 and VEGF may be more meaningful for the evaluation of clinical prognosis.

Objective To observe levels of the serum albumin and their association with prognosis in children with hand-foot-and-mouth disease (HFMD) . Methods A total of 122 HFMD children admitted from 2011 to 2013 were selected and divided into three groups:common group (n=57), severe group (n=52) and critical group (n=13). Serum albumin levels, blood glucose levels, peripheral blood white cell counts of the children in the three groups were compared within 24 hours of admis-sion. Moreover, the incidence of hypoalbuminemia and mortality of the children were analyzed in each group. Results In critical group, serum albumin levels were signiifcantly decreased while blood glucose levels and peripheral blood white cell counts were signiifcantly increased than those in the severe group and common group, and the differences were all statistically signiifcant (all P<0.05). There were no signiifcant differences in serum albumin levels, blood glucose levels and peripheral blood white cell counts between severe group and common group (all P>0.05). There was no hypoalbuminemia and death in severe group and common group. The percentage of hypoalbuminemia and mortality of children in critical group were higher than those in the other two groups (all P<0.01). Conclusions The mortality was extremely high in children with critical HFMD. The decrease of serum albumin levels was a high risk factor for death in children with critical HFMD. Early and dynamic monitoring serum albu-min levels may be helpful in evaluation of disease condition and prognosis of HFMD.

Objective To study clinical signiifcance of single tidal breathing testing in bronchiolitis. Methods Infants with bronchiolitis at ifrst wheezing (bronchiolitis group, n=756), and 115 infants with bronchopneumonia (bronchopneumonia group) hospitalized were enrolled. Tidal breathing parameters were analyzed in two groups. Bronchiolitis group was divided according to percentiles of the fraction of exhaled time at peak tidal expiratory lfow to total expiratory time (TPTEF/TE). The episodes of recurrent wheezing of infants below the 20th or above the 80th percentile of TPTEF/TE were followed up by phone calls within 1 year after discharge from the hospital. Results There were signiifcant differences in TPTEF/TE, VPEF/VE, Ti, Ti/Te, TEF75 and TEF50 between bronchiolitis group and bronchopneumonia group. The recurrent wheezing rate of infants with bronchiolitis below the 20th percentile of TPTEF/TE was signiifcantly higher than that above the 80th percentile of TPTEF/TE (37.5%vs 11.3%). Conclusions There is the greater possibility of recurrent wheezing in the infants with the more serious airway obstruction relfected by single tidal breathing testing in bronchiolitis.

Objective Gas chromatography-mass spectrometer (GC-MS) technology combined with Heuristic evolving latent projections (HELP) method were used to qualitatively analyze the volatile oil of fructus lycii (Lycium barbarumL.)Methods With the best temperature-programmed chromatographic condition, overlapping peaks among the total ion chromatogram were separated. Then an automatic mass spectral deconvolution and identification system (AMDIS) was used to identify volatile components comprehensively. Finally, the pure chromatographic peaks were matched with NIST 05a mass spectra library for giving the precise qualitative result. Results Totally, 29 compounds in fructus lycii (Lycium barbarum L.) were identified accurately.Conclusions Compared with the traditional qualitative analysis method, the new established method which GC-MS technology combined with HELP could get tremendous advantages. It not merely enhanced the accuracy of identification but also solved the bottleneck of handling the inseverable compounds.
