OBJECTIVE:To investigate the status quo and problems of application of parenteral nutrition in our hospital. METHODS:Cases of parenteral nutrition support(PN)from January to June in 2008 were reviewed and analyzed statistically. RESULTS:The problem of 637 patients treated with PN included indication,duration,prescription composition and incompatibility. CONCLUSION:The application of PN in our hospital is partly rational,nevertheless there are also some problems needed to be improved.

strains that could produce raw starch-digesting glucoamylase were isolated from soil and mildewed rice.The highest raw starch-digesting glucoamylase activity strain named OR-1 was identified as Rhizopus.sp.The raw starch-digesting glucoamylase activity of the strain is 90U/mL.Through UV and NTG mutagenesis,the raw starch-digesting glucoamylase activity raised to 200U/mL and 325U/mL respectively.The RDA were 70% and 65% respectively.

Objective:To summarize the drug repercussion data in outpatient pharmacy and analyze the reasons to provide sugges-tions for the improvement. Methods: The information was collected from the hospital information system ( HIS) during January 1, 2013 and December 31, 2015, including drug name, category, quantity, amount, reasons for drug repercussion and the other statisti-cal data. Results:During the three years, the number of prescription drugs, amount of money and varieties of drug repercussion were increased. The most common reasons for drug repercussion were the other reasons, withdrawn by doctors and the request of patients. The sum of drug repercussion was positively correlated with the drug price and the amount of drug repercussion. Conclusion:The op-tion simplicity for drug repercussion in HIS is the main reason for drug repercussion bythe other reasons. The occurrence of drug re-percussion should be intervened by such methods as gradually improving the HIS, establishing intervention measures, enhancing the professional quality of pharmacists and so on.

Objective To investigate the toxic effect of nona-ferroso-ferric oxide(Nano-Fe_3O_4),nano-silicon dioxide(Nano- SiO_2)and single walled carbon nanotubes(SWCNTs)on the lung and mechanism in rats.Methods Fourty-nine Wistar rats were randomly divided into 7 groups,the control group,low and high dose groups of three nanomaterials.The rats were exposed by intratracheal instillation once two days for 5 weeks,and then killed by abdominal aorta bloodletting.The pathology of lung,lactate dehydrogenase(LDH),total antioxidant capacity(T-AOC),superoxide dismutase(SOD),malondialdehyde(MDA),interleukin-1(IL- l),interleukin-6(IL-6)and tumor necrosis factor-?(TNF-?)in bronchoalveolar lavage fluid(BALF)were determined.Results The fibrous tubercle and the matrix inflammation of lung tissue was found in the experimental groups.The activities of T-AOC and SOD decreased while IL-6 concentration increased significantly in the experimental groups(P

Aim To establish a reliable and practical rat model with hypertension induced by DOCA-Salt.Methods One week after nephrectomy,the rats were subcutaneously injected with DOCA (30 mg?kg-1) once a week and fed with a chaw with 10 g?L-1NaCl plus 2 g?L-1 KCl in drinking water for 4 weeks. Blood pressure was measured and,urine was collected for measurement of volume(UV),UNaV,UClV,UKV,UCaV and pH values,once a week. SGPT,CREA,SUGA,TRIG,CHOL,INS,ALD,ADH were measured in circulating blood samples. Kidney morphological changes and Na+,K+-ATPase activity of the renal tubular epithelial cells were also examined. Results Blood pressure,UV,UNaV and UClV were increased and histopathological changes of the kidney such as glomerulus sclerosis and tubular pachynsis were observed in the DOCA-Salt rats. Whereas UKV,UCaV,urine pH values,SGPT,CREA,SUGA,TRIG,CHOL,INS,ALD and ADH were not changed. In contrast,Na+,K+-ATPase activity of the renal tubular epithelial cells was decreased. Conclusion DOCA-Salt is a reliable hypertensive model with sodium retention.

Castor(Ricinus communis L.),a high energy-stored and industrial raw-material plant species,is of great value in its application.Progresses in castor biotechnology were summarized in terms of tissue culture and genetic transformation.The results of studies on tissue culture indicated that application of TDZ(thiadiazuron) gave the maximum rate of shoot proliferation in various exogenous hormones when embryo axis was used as explant.On this ground,the in vitro regeneration system was established.The studies on castor genetic transformation showed that the Agrobaterium-mediated method was the most suitable one in different castor transformation methods.The hygromycin is suitable to selection of castor transfomants while castor embryo axis is insensitive to kanamycin.The possibilities of breeding of new castor varieties and improvement of castor production via biotechnology were also discussed.

Objective To investigate the efficacy of laparoscopic surgery for intestinal atresia in neonates.Methods A perspective study,from February 2002 to November 2006,a series of 61 newborns with intestinal atresia were randomly divided into laparoscopic and open surgery groups.The intra-and post-operative records of the two groups were compared.Results The survival rate and postoperative complications of the two groups were similar (29/31 vs 28/30,x~2=0.001,P=0.973;and x~2=1.298,P= 0.862).In the laparoscopic group,the intestine was pulled out through the umbilical trocar and then resected;the umbilical area was normal after intestinal anastomosis;no scars or only small scars were observed on the abdomen after the operation.The two groups were followed up for 6 to 18 months.During the period,3 patients showed enterocolitis (2 in the laparoscopic group and 1 in the open surgery group);3 patients developed adhesive intestinal obstruction (1 in the laparoscopic group and 2 in the open surgery group), both the complications were cured by conservative therapies.Conclusions Laparoscopic surgery is simple,safe,and effective for intestinal atresia in newborn.

BACKGROUND: Previous studies have demonstrated that acidic fibroblast growth factor (aFGF) combined with partially deproteinized bone (PDPB) (aFGF/PDPB) well promotes avascularization in animals with early-stage avascular necrosis of the femoral head (ANFH), but the histological results remain unknown.OBJECTIVE: To observe the histological repairing effects of aFGF/PDPB on early-stage ANFH in rabbits. METHODS: New Zealand rabbits were established models of bilateral ANFH and were randomly divided into a blank group, a simple PDPB group, and an aFGF/PDPB group. PDPB and aFGF/PDPB bone were implanted into the PDPB and aFGF/PDPB group accordingly. The blank group did not receive any implantation. At 2, 4, and 8 weeks after surgery, all animals were sacrificed for histological examination to observe the osteogenesis by hematoxylin-eosin staining.RESULTS AND CONCLUSION: Defects were filled with granulation tissues and fibrous connective tissues, only a little osteoid tissue formed at the borderline in the blank group at the end of the 8th week. In the PDPB group, a little new bone and cavitas medullaris formed. At 8 weeks, lots of graft was absorbed and cavitas medullaris formed with more osteoplasts and myeloid cells in it. The osteogenesis in the aFGF/PDPB group was better than that of PDPB group in each time point. At 4 weeks, the transplanted cavity was filled with osteoid tissues, a lot of osteogenic precursor cells and osteoblasts could be seen. Plenty of micrangium was observed, and osteoid tissues began to rebuild. At 8 weeks, the graft was replaced by bone tissues, and cavitas medullaris were formed with lots of bone marrow cells in it. At the borderline of the bone trabecula, there were lots of osteoplast and little osteoclasts, which may play a role in bone remodeling. There were mature bone cells in bone lacuna. Results indicate that aFGF/PDPB has better repair effect on rabbit model of ANFH than that of simple PDPB.

Objective To explore the value of color Doppler ultrasonography and plasma D-dimer in diagnosis of lower limb deep venous thrombosis (DVT).Methods The clinical data of 70 cases of patients with lower limb DVT diagnosed clinically were retrospectively studied.The lower limb venous of each patient was examined by color Doppler ultrasonography and the plasma level of D-dimer were measured,furthermore the plasma levels of D-dimer in different phase and different type of thrombosis were compared.Results The sensitivity,specificity,positive predictive value,negative predictive value,and accuracy of plasma D-dimer and ultrasonography examination in lower limb DVT were 100%,66.7%,97.0%,100%,and 97.1%,and 98.4%,83.3%,98.4%,83.3%,and 97.1%,respectively.The plasma D-dimer in acute phase 〔(6 451?4 012.22) ?g/L〕 and subacute phase 〔(2 063?1831.35) ?g/L〕 of lower limb venous thrombosis were significantly higher than that in normal control group 〔(310?66.70) ?g/L〕,P

Objective To explore the role of graph-text-combined health education in dieting health education for patients with hematologic diseases. Methods About 56 patients with hematologic diseases hospitalized in February 2015 were assigned as the control group and another 57 patients with the same diseases during March to April 2015 as the experiment group. In the control group, routine dieting health education was done and in the latter the graph-text-combined health education was used for the dieting health education. The two groups were compared in view of recognition on dieting knowledge, dieting compliance and patient's satisfaction level. Result The recognition on dieting knowledge, dieting compliance and patient's satisfaction level were all higher those of that the control group (P<0.05). Conclusions The graph-text-combined health education can improve the recognition on dieting knowledge, dieting compliance and patient's satisfaction level when it is used in the health education for the patients with hematologic diseases. Therefore, it is worth clinically popularizing.
