Objective To apply Plato analysis method to clinical cases which were reported from clinical nursing, finding out the key link of the risks which were related to the cases:the key age, the key period, the key spectrum of disease and the key projects, etc. To carry out the feedforward control of the quality of care, and ensure the quality and safety of nursing. Methods A database were set up including clinical special cases, high-risk cases, security hidden danger cases and emergency cases. Thetwo eightprinciple of Plato analysis method was used to find out the main factors, the principal contradiction, the key hazard and the key problems of the cases, etc. The aim was to provide guidelines of risk analysis, risk prevention and risk aversion for nurses, and improve their consciousness of security hidden danger, and reduce security hidden danger cases. Results The results of 207 cases collected from 2014 to 2015 showed that the main risks involved the age groups were 41-80 years old and 21-30 years old. The major risks involved the spectrum of disease were the nervous system, cardiovascular disease, surgical anesthesia related problems, kidney disease, cancer and respiratory system. The major risks involved the time were the midnight, morning and afternoon. The major risks involved the locations were sickroom, emergency room, auxiliary inspection departments and outpatient. The major risks involved items were disease mutation, psychological problems, medication safety and instrument safety, among the disease mutation, timely discovered, rescued 13 patients with heart and breathing pause, stop 13 patients who attempted suicide. Since the Plato analysis method was applied to identify the security risks of the clinical cases, the number of falling, all kinds of pipe shed, skin problems and suicides were decreased from 6, 6, 7, 5 in 2014 to 2, 2, 2, 1 in 2015, declining trend year by year. Conclusions Applying the Plato analysis method to identify the security risks of the clinical cases which can find out the main problems of cases and improve nursing quality and management efficiency.

Objective To investigate the effect of anisodamine on oxygen metabolism and organ function in dogs with sepsis.Methods Twenty beagles were divided into sepsis group (n =8) and anisodamine-treated group (n =12) according to the random number table.The sepsis model was established by cecal ligation and puncture.Changes in thrombomodulin (TM),arterial oxygen partial pressure (PaO2),oxgen uptake rate (ERO2) and lactate were mearsured before and 1,3,8 and 24 h after operation.Wet/dry ratio of lung tissues and incidence of multiorgan dysfunction syndrome (MODS) were detected 24 h after operation.Results Level of TM was increased progressively after operation,which was significantly higher in sepsis group than in anisodamine-treated group at 3,8 and 24 h [(28.7±15.9) vs (19.5 ±10.6)ng/ml,(36.5±20.8) vs (21.9±12.8)ng/ml,(52.6±32.7)vs (31.3 ± 18.4)ng/ml respectively] (P ＜ 0.05).The PaO2 decreased slowly after operation,with the decrease more significant in sepsis group than in anisodamine-treated group at 24 h [(65.6 ± 14.5) vs (83.3 ± 16.3)mmHg] (P ＜0.05).The ERO2 had a rise-and-fall trend after operation,with the level lower in sepsis group than in anisodamine-treated group at 24 h [(16.7 ± 3.1) ％ vs (21.7 ± 2.9) ％] (P ＜ 0.05).Level of blood lactate increased gradually,with the level higher in sepsis group than in anisodamine-treated group at 24 h [(4.4 ± 1.2) vs (3.1 ± 0.8) mmol/L] (P ＜ 0.05).Wet/dry ratio of lung tissues in sepsis group was (510 ± 80) ％ versus (370 ± 50) ％ in anisodamine-treated group at 24 h (P ＜ 0.05).Incidence of MODS in sepsis group was 38％ versus 17％ in anisodamine-treated group at 24 h (P ＜ 0.05).Conclusion Anisodamine may ameliorate the injury to vascular endothelial cells and oxygen metabolism disorder after sepsis and hence contributes to the reduction of sepsis-induced MODS.

Objective To evaluate the efficacy of intravenous immunoglobulin (IVIG) in the treatment of severe EV71 infection in children.Methods The clinical data of children with severe EV71 infection,who admitted in our hospital from January 2010 to November 2012 were retrospectively analyzed.According to the time of admission and treatment principles,the patients were divided into the 2010 group and the 2012 group.The patients of the 2010 group routinely received IVIG treatment,but patients in the 2012 group received IVIG treatment in serious condition.The obvious effective rate,effective rate,ineffective rate,the incidence rate of critically ill and mortality of the two groups were compared.Results There were no significant differences in the obvious effective rate (86.0％ and 85.2％),effective rate (9.6％ and 11.8％),ineffective rate (4.4％ and 3.0％),the incidence rate of critically ill (4.0％ and 2.2％) between the two groups (x2 =0.011,1.269,1.657,3.304,all P ＞ 0.05).The mortality of the 2010 group (2.8％) was higher than that of the 2012 group (0.6％)(x2 =8.213,P ＜0.05).Conclusion IVIG has no effect on patients with severe EV71 infection,and is not recommended.

Objective To study the changes and significance of CD4+CD25+ regulatory T cells and C-reactive protein(CRP) in patients with acute exacerbation of chronic obstructive pulmonary disease(COPD). Methods Flow cytometry was used to detect the frequency of CD4+CD25+ regulatory T cells in peripheral blood from 36 patients with acute exacerbation of COPD( COPD group) and 36 patients with clinical stability of COPD(control group one)and 36 normal individuals(control group two). The level of CRP was detected routinely. Results The ratio of CD4+CD25+ regulatory T cells number in peripheral blood of COPD group to the total number of CD4+T cell was (2.56±1.83 )%, and it was significantly decreased compared to the other two groups (P all<0.01 ). The level of CRP in COPD group was markedly higher than that in the other two groups (P all<0.01 ). The level of CD4+CD25+ regulatory T cells in patients with acute exacerbation of COPD had negative relation with CRP. Conclusions CD4+CD25+ regulatory T cells participate in inflammatory response. The proportion of CD4+CD25+ regulatory T cells decreases in patients with acute exacerbation of COPD, and it may result in maladjustment of cytoimmunity.

To study the coumarins of Anemone raddeana Regel, the compounds were separated by silica gel column chromatography and HPLC.

Two new compounds were isolated and identified as 4, 7-dimethoxyl-5-methyl-6-hydroxy coumarin (1) and 4, 7-dimethoxyl-5-formyl-6-hydroxycoumarin (2). The bioassays indicated that compounds 1 and 2 could significantly inhibit the proliferation of cancer cell, and showed the agonist effect on the transactivity of retinoic acid receptor-alpha (RARalpha). In addition, the two compounds had inhibitory effect against human leukocyte elastase (HLE).

Objective To investigate the effects of thyroid hormone on extremely severe traumatic brain injury (TBI).Methods A retrospective case-control study was conducted to analyze the treatment of 105 patients with extremely severe TBI admitted from July 2010 to April 2014.There were 79 males and 26 females,with an average age of 32.9 years.The patients were divided into conventional treatment group (Group A,35 cases),conventional treatment ± thyroxine treatment group (Group B,35 cases) and thyroxine treatment group after the condition that thyroxine level was low (Group C,35 cases) according to the random number table method.The incidence of low T3 and T4,incidence of hypotension,the dosage of vasoactive drugs,function evaluation of liver and kidney damage,Glasgow outcome scale (GOS),and acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) within 20 days after admission,and mortality rate within 30 days after admission were compared and analyzed.Results Within 20 days after admission,the rates of low thyroxine levels and hypotension of the Group B (22.9％,77.1％) were significantly lower than those in the other two groups (Group A:40％,100％;Group C:37％,100％) (all P ＜ 0.05).The doses of dopamine and norepinephrine in Group B was significantly lower than the other two groups and the combination rate of vasopressors in Group B was significantly lower than the other two groups (P ＜ 0.05),while there was no significant difference between Group A and Group C (P ＞ 0.05).The corresponding data in Group A and Group C had no statistically significant difference (P ＞ 0.05).The liver and renal dysfunction rates of Group B (29％,31％) were significantly lower than those of the other two groups (Group A:49％,51％;Group C:43％,51％) (all P ＜ 0.05).The corresponding data in Group A and Group C had no statistically significant difference (P ＞ 0.05).GOS in Group B [(4.8 ± 1.9) points] was significantly higher than that in Group A [(3.3 ± 0.2) points] (all P ＜ 0.05) within 30 days after admission and significantly higher than that of itself at the beginning [(3.6 ± 1.1) points] (P ＜ 0.05).The APACHE Ⅱ in Group A was significantly higher than those in other two groups as well as that in Group A at admission (P ＜ 0.05).Mortality rates in Group B (31％) and Group C (29％) were significantly lower than that in Group A (69％) within 30 days after admission (P ＜ 0.05).Conclusions Thyroxine can reduce the incidence of hypotension,liver and kidney injury rate in extremely severe TBI.Prevention is better than the supplementary treatment after severe TBI.Thyroxine can also reduce the mortality of extremely severe TBI within 30 days after admission.

Objective:To investigate the clinical features and etiology of 176 children with liver dysfunction, and to provide reference for the diagnosis and treatment of children with liver dysfunction.Methods:From April 2017 to February 2019, 176 children with liver function abnormalities from 2 months to 13 years old who were admitted to Hangzhou Children's Hospital were selected inthe study.The pathogens of the children's secretions were detected by fluorescence quantitative method.The blood was tested for hepatitis B virus, hepatitis C antibody and hepatitis A antibody, and blood culture method was used to detect and identify bacteria, and blood genetic metabolism and coagulation function were also screened.According to the age of the children, they were divided into infant group, toddlergroup, preschool group and school age group.Results:Among the 176 children, the infants had the most abnormal liver function, 93 cases(52.84%), followed by 43 children (24.43%) in the toddler group.Causes of the disease: 138 cases (78.41%) of the original diseases, 8 cases (4.55%) of non-infectious diseases, 30 cases (17.04%) of the undetected pathogens.Among the 138 cases with liver function abnormality due to infectious diseases, 123 cases (89.13%) were infected with virus, 8 cases (5.80%) were infected with bacteria, 6 cases (4.35%) were infected with mycoplasma, and 1 case (0.72%) was infected with Toxoplasma gondii.Among the 123 cases of liver dysfunction caused by viral infection, cytomegalovirus was detected in 62 cases (50.41%), followed by EB virus in 38 cases (30.89%), rotavirus in 10 cases (8.13%), and EV71 virus in 5 cases (4.07%), 4 cases of common enterovirus (3.25%), 2 cases of respiratory syncytial virus (1.63%), 1 case of herpes simplex virus and Coxsackie A16 virus (0.81%). Pre-school and above were mainly infected with EB virus; the age>1 year-old liver function abnormality was 37.10% (23/62) due to cytomegalovirus, and the proportion of EB virus infection was 92.11% (35/38). Compared with 62.90% and 7.89% of age 2 months to 1 year, the difference was statistically significant (χ 2=29.27, P=0.00). Eightcases of liver infection caused by bacterial infection: 3 cases of Staphylococcus aureus, 2 cases of Streptococcus pneumoniae, 2 cases of Escherichia coli, and 1 case of Pseudomonas aeruginosa.There were 3 cases of genetic metabolic diseases, including 2 cases of hepatolenticular degeneration and 1 case of glycogen accumulation.Characteristics of liver function abnormalities in children: the main clinical manifestations of children were jaundice, splenomegaly and hepatomegaly, cough, diarrhea, etc.Outcome: 98 cases (55.68%) were healed, 60 cases (34.09%) were improved, and 17 cases (9.66%) were aggravated, 1 case of death (0.57%). Conclusion:The abnormal liver function of infants was mainly caused by virus infection, especially cytomegalovirus.Infants and young children have no obvious symptoms in the early stage of the disease, severe cases can be manifested as jaundice and hepatosplenomegaly, mainly mild, with a good prognosis.

Objective To explore the influence of Neuman theory on postoperative mental status of the patients with hypertensive cerebral hemorrhage. Methods According to their admission order, 120 patients with hypertensive intrac-erebral hemorrhage who accepted operation in our hospital from June 2011 to January 2014 were divided into the ex-perimental group and the control group, each group with 60 patients. The patients in the control group were treated with routine care while the patients in the experimental group were given psychological care interventions designed in ac-cordance with Neuman theory on the basis of the routine care. The nursing effects of the two groups were compared, detected and evaluated by Hamilton Depression Rationg Scale (HAMD) and Self-reporting inventory (SCL-90). Results The differences of HAMD total score of the two groups before interventions were not statistically significant. After 12 weeks intervention, HAMD total score of the experimental group significantly improved, especially in hopelessness, anxiety/somatization and cognitive impairment. The depression, anxiety, obsessive-compulsive symptoms, horror, hostility and psychosis of the experimental group were significantly lower than those of the control group after 12 weeks inter-vention. Conclusion Neuman theory has very high value of application to improve postoperative psychological status of the patients with hypertensive cerebral hemorrhage and is worthy of being promoted and applied in clinical work.
