Objective To evaluate application of quality care in prevention of general surgery wound infection in elderly patients. Methods 116 cases of elderly patients undertook general surgery from October 2013 to October 2014 were selected in alphabetical order by pinyin of last name as the research objects, who were divided into the observation group (58 cases) and control group (58 cases) by lottery. The control group received routine care, the observation group received quality care. The occurrence of wound infection and the hospitalization time were compared. Results The incidence of wound infection of the observation group was 6.9%(4/58), which was lower than that of the control group [24.1%(14/58),χ2=6.576, P<0.05]. The hospitalization time of the observation group was lower than that of control group [(22.6±3.2) d vs.(28.6±3.8) d, t=5.401, P<0.05]. Conclusions Quality care contributes to reduce the incidence of wound infection on general surgery incisions of elderly patients, and promotes the recovery of patients.

Objective To explore the levels of neuron-specific enolase(NSE)in serum and cerebrospinal fluid(CSF) of children with convulsion,and its significance to the diagnosis of neuronal damage was evaluated.Methods Sixty patients were enrolled,and they were divided into 4 groups:non-nervous system disease group,peripheral nervous system disease group,brief convulsion group,and prolonged/status convulsion group.The levels of NSE in serum and CSF were detected in 4 groups,and the electroencephalography(EEG) and computed tomography/magnetic resonance imaging(CT/MRI) examinations were taken to observe the changes in patients with convulsion.Results The levels of NSE in serum and CSF of children with convulsion increased significant,especially in the prolonged/status convulsion group.Changes of NSE levels in serum and CSF were similar.Meanwhile,significant changes were found in EEG between the brief convulsion group and prolonged/status convulsion group;but no significantly changes were found in CT/MRI between the 2 groups.Conclusions NSE detection might be valuable to the diagnosis for neuronal damage in early time.The changes of NSE levels are similar to those in EEG,which are more sensitive than the changes in CT/MRI.It is very important to combine the NSE detection in serum or CSF and EEG examination in early time after convulsion for judgement to the neuronal damage and prognosis.

Objective To investigate quitting motivation of smoking patients with mild and moder-ate chronic obstructive pulmonary disease ( COPD) and evaluate the effects of smoking cessation methods based on cognitive intervention.Methods A total of 102 smoking patients with mild and moderate COPD from the outpatient department was divided into 4 blocks according to their intention of quitting smoking.Pa-tients in each block were randomly divided into intervention and control groups.Results ⑴All the re-spondents were at an average age of (61.3 ±12.3) years old.The sex ratio of men to women was 99∶3. The average smoking index (bag/year) in all the respondents was (39.81 ±11.53).The average daily smoking was (14.22 ±2.30) packs.The respondents with a lower degrees accounted for 55.9%and the respondents with high nicotine dependence 49.0%.A total of 39 people (38.2%) hoped to give up smok-ing, 20 people (19.6%) strongly hoped to give up smoking.⑵The main reasons for smoking included en-joyment (7.02), dependence (6.88), and calm (6.55).⑶There were statistically significant difference in the half-year continuous abstinence rates (χ2 =4.993, P =0.025) and in June quit rates (χ2 =6.668, P =0.010) between the intervention (58.82%) and control (33.33%) groups.The weight gain had sig-nificant difference between the intervention and control groups at the 3rd month ( t =2.65, P <0.01) or 6th month ( t =2.07, P <0.05) after quitting smoking.Conclusions The quitting motivation of smoking patients with mild and moderate COPD is not strong, while the smoking cessation methods based on cogni-tive intervention are effective for those patients.

Objective To investigate the therapeutic effieacy and safety of 18 α-Diammonium glycyrrhizinate phosphatidylcholine complex (DGPC) in patients with chronic hepatitis B and or C with elevated aminotransferase. Methods 55 patients with chronic hepatitis B and or C, with serum alanine aminotransferase (ALT) of 2 to 10 times the upper limit of normal were randomly assigned to receive DGPC or Diammonium glyeyrrhizinate (DG) for 12 weeks. Then they were followed up for an additional 4 weeks. From week 1 to 10, DGPC or DG was given as 150 nag,three times a day (TID). At the 11th week,the drug was given as 100 mg,TID. Then 50 mg,TID for the 12th week. Results ALT was markedly decreased after receiving DGPC 4,8,12 weeks (P=0.00). ALT normalization rate at the end of therapy was similar (38.5% vs 34.5% ,P =0.76). Drug-related adverse events were similar. Conclusion DGPC can rapidly and safely decrease aminotransferase in patients with chronic viurs hepatitis.

Objective To investigate the therapy and influencing factors for prognosis of ventilator-associated pneumonia(VAP) caused by multidrug-resistant organisms(MDROs).Methods 169 patients with VAP who were admitted to a hospital between January 2012 and December 2013 were included in analysis, 125 were in MDRO infection group and 44 in non-MDRO infection group.MDRO infection group was subdivided into MDR-A group(n=78, resistant to selected antimicrobial agents) and MDR-B group (n=47, sensitive to at least one kind of selected antimicrobial agent).Antimicrobial choice and prognosis between each group were analyzed and compared.Results 242 strains of pathogenic bacteria were isolated from airway secretion of VAP patients, 173(71.49％) were MDROs.The major pathogens causing VAP were Klebsiella spp.(n=66), Pseudomonas aeruginosa(n=64), Acinetobacter spp.(n=60), Staphylococcus aureus(n=27), and Escherichia coli (n=17), the percentages of MDROs of above pathogens were 68.18％, 50.00％, 91.67％, 88.89％, and 76.47％ respectively.The prognosis of MDRO infection group was poorer than that of non-MDRO infection group, MDR-A group had the worst prognosis(P<0.001).Persistent fever, leukocytosis, and progress of pulmonary inflammation in VAP patients suggested poor prognosis(all P<0.001);antimicrobial use in patients with effective therapy was higher than those in a worsened condition before onset, at the beginning of onset, and after culture of specimens(all P<0.001), while coma, early-onset VAP and multiple bacterial infection had no prognostic significance in patients with VAP(all P>0.05).Conclusion There is high incidence of MDRO infection in patients with VAP, effective antimicrobial therapy can improve the prognosis.

OBJECTIVE: To establish an HPLC method for the content determination of prostaglandin A1 and prostaglandin B1 in Alprostadil for injection.METHODS: The determination was performed on Alltech Alltima C18 column with mobile phase consisted of phosphate puffer(pH=6.3)-acetonitrile-methanol(70 ∶ 25 ∶ 5) at a flow rate of 1.5 mL? min-1.The detection wavelength was set at 196 nm.The column temperature was set at room temperature and the injection volume was 20 ?L.RESULTS: The prostaglandin A1 and prostaglandin B1 were well separated from main component and other impurities.The linear range of prostaglandin A1 and prostaglandin B1 were 0.175～19.00 ?g?mL-1(r=0.999 7) and 0.23～19.90 ?g?mL-1(r=0.999 2).The contents of prostaglandin A1 in 3 batches of samples were 4.7%,4.9% and 4.3%,and the contents of prostaglandin B1 in 3 batches of samples were 0.6%,0.8% and 0.5% respectively.CONCLUSIONS: This method is proved to be simple,specific and suitable for the content determination of related substances in Alprostadil for injection.

Chronic liver diseases can further develop to liver fibrosis and cirrhosis. Currently, there is no effective treatment except liver orthotopic transplantation at this point. The extreme shortage of liver organ source forced people to find alternative treatment strategies. Mesenchymal stem cells ( MSCs) have the abilities of immunomodulatory, hepatocyte differentiation, promotion of liver cells regeneration in situ and inhibiting the activation of hepatic stellate cells. Therefore, MSCs transplantation provides a very broad prospect for cell therapy. It is important to provide preclinical evaluation of the efficacy and safety before the application of cell therapy in clinical trials. The progress of various animal models of human liver diseasees and significance of using MSCs to treat liver diseases in preclincal studies based on these animal models were reviewed in this paper.
