Objective To understand true feelings of patients with malignant tumor after implementing the protective medical treatment.In order to provide more humanized service for clinical nursing and to improve the job satisfaction of nurses.Methods The phenomenological methods of qualitative research was applied to carry out interviews with 12 patients to collected data.Then the data were analyzed.Results After reading,analysis,reflection,classification and refining the theme,we drew the following themes:(1)Before knowing diagnosis:half-believe and anxiety.(2) At the time of knowing diagnosis:luck,avoidance,acceptance and facing; (3) After knowing diagnosis:thirsting for information,low self-worth,improving self motivation.Conclusions We should not insist on hiding malignant tumor patients.Individualized and targeted measures should be taken to make patients cope with diagnosis better and improve the quality of their life.

Object ive To find related risk factors after PEIT under ultrasound .Methods We collected the data of 73 clinical PEIT cases from January 2007 to December 2011 .Univariate analysis found the related risk factors of PEIT.Multivariate analysis identified the independent risk factors .Results Single factor analysis showed that the differences between groups of patient′s sex,age,the positive and negative of serum HBsAg ,tumor location,tumor number in survival rates were not statistically significant;the differences in groups of tumor size , serum AFP levels,with or without portal vein tumor thrombus ,liver function(Child)grade,tumor type in survival rates were significant differences .Multivariate and stepwise regression analysis showed that liver function ( Child) grade,tumor type,tumor metastasis,portal vein thrombosis were factors relevant to prognosis ;all chi-square test,χ2=47.763,P<0.01;likelihood ratio test χ2=450.546 ,P<0.01.Conclusion liver function ( Child-pugh grade),pathological type of tumors,tumor′s metastasis,emboli in portal vein are the risk factors after PEIT .

Objective To study the clinical investigation of andrographis paniculate in treatment of infantile respiratory infection.Methods 260 cases who were confirmed diagnosed of infantile respiratory infection were divided into the therapy group with androgrophis paniculate and the control group with ribavirin at random.Results The therapy group was better than the control group,and there were outstanding differences between two study groups.Conclusion Andrographis paniculate can shorten the course of the disease,and improve the patients' symptoms and it is more safety than the ribavirin.

35 % and the intraoperative blood loss was expected to be 800-1 600 ml. The operations were performed under combined general-epidural anesthesia. General anesthesia was induced with fentanyl 2-4 ?g?kg-1 , thiopentone 5 mg?kg-1 and succinylcholine 1.5mg? kg-1 and maintained with isoflurane inhalation and intermittent iv boluses of vecuronium. Epidural anesthesia was performed at T5-6 (thoracic surgery), T10-11 (upper abdominal surgery) or L3-4 (lower abdominal surgery) . A mixture of 0.1% lidocaine +0.2% dicaine was used for epidural block during operation. The patients were randomly divided into 2 groups: (1) ANIH group ( n = 18) and (2) AHH group ( n = 20) . Blood volume (BV) was calculated according to following formula: BV (ml) (male) = Height (cm)? 28.5 + Body weight (kg) ? 31.6 - 2 820,BV(ml) (female) = Height(cm)? 16.25 + Body weight (kg) ? 38.46 - 1 369. 1 000-1 200 ml of 6% HES (200/0.5) and 500 ml of lactated Ringer's solution (about 25%-30% of BV) were infused at a rate of 50ml?min-1 when induction of anesthesia was started in both groups. In group I (ANIH) 400-600 ml of blood (about 10%-15% of BV) was removed through radial artery before induction of anesthesia. The removed blood was reinfused at the end of surgery. Vital signs (BP,HR,CVP and ST-T changes) , Hct, oncotic pressure and arterial blood lactate concentration were monitored during operation. Results The vital signs were fairly stable during perioperative period in both groups. Transient hypotension developed in 16.7% (3/8 in group Ⅰ ) and 15.0% (3/20 in group Ⅱ ) of patients during induction of anesthesia. CVP was significantly elevated in both groups but the increase in CVP was significantly higher in group Ⅱthan that in group Ⅰ . In group Ⅰ (AN1H) moderate hemodilution was achieved (Hct = 29.9% 2.9%) while in group Ⅱ (AHH) only mild hemodilution was achieved (Hct = 32.9% ?2.9%) .Hct was significantly higher in group Ⅰ(31.5% ?5.1%) than that in group Ⅱ (27.7% ?3.6%) at the end of surgery. Blood loss was comparable between the two groups, and oncotic pressure and blood lactate level were within normal range in both groups. Conclusion ANIH is more effective and safer than AHH without obvious adverse effects, and can avoid exceedingly high CVP commonly seen in AHH. ANIH is a hemodilution technique of choice in the elderly patients.

Retinal neovascularization is a complicated pathophysiological process as a result of imbalance between angiogenic and anti-angiogenic factors. Correct understanding of the signaling pathways,exploring the critical factors involved in retinal angiogenesis, looking for new strategies by reconstructing the new vessels are helpful for knowing the mechanism of the occurrence and development of reitnal neovascularization, which would be good for preventing and treating retinal neovascularization diseases.

After the necessity of using medical news information and the advances in its automatic indexing were analyzed, a novel automatic controlled indexing method of medical news text was put forward. The method intro-duced translated MeSH vocabulary as the main indexing words, merging Chinese commonly used word segmentation dictionary, then calculated word frequency for document text which added split token and sorted it, choose top 5 high-frequency words in MeSH vocabulary indexed document after deleting high-frequency words not in MeSH vo-cabulary.

Objective To evaluate the association between C-reactive protein (CRP) blood levels and specific survival time of non-small cell lung cancer (NSCLC) patients treated with chemotherapy.Methods Data from 96 advanced (stage ⅢB/Ⅳ) NSCLC patients were analyzed.All patients were divided into two groups based on the enrolled time as follows the initial treatment group (48 cases) and retreatment group (48 cases).According to 0.6 mg/L and 7.3 mg/L of CRP which were the 1/3 and 2/3 of CRP concentrations,respectively,the 96 patients were divided into low,intermediate and high groups.Kaplan-Meier and Cox proportional-hazard models were used to evaluate the relationship between the CRP level and survival time.Results After adjusting for age,sex,smoking history,histological type and stage of lung cancer,a significant relationship between CRP and survival time was observed (P ＜ 0.05).Such significant differences of survival time were also observed in both of the adenocarcinoma (P ＜ 0.001) and squamous with poorly differentiated (P =0.032) subtypes.On stratification analysis by chemotherapy status,the circulating CRP level in retreatment group was correlated well with survival time (P ＜ 0.001).However,the influence of circulating CRP levels on survival time in initial group did not reach statistical significance (P =0.296).For all patients,the hazard ratio with high CRP levels for NSCLC-specific survival was 1.15 (95 ％ CI 0.82-1.61) compared with that of low CRP levels.The hazard ratio for the initial treatment group and retreatment group were 0.52 (95 ％ CI 0.16-1.74) and 1.77 (95 ％ CI 0.73-4.26),respectively.Patients with high circulating CRP level also responded poorly to chemotherapy.Conclusion A high level of circulating CRP is associated with an inferior response and survival outcome in NSCLC patients treated with chemotherapy.

The strategies for automatic extraction of key words from medical news were put forward by adding the MeSH terms into the general classification table in combination with the length of MeSH terms and location-weigh-ted MeSH terms.The key words randomly selected from 100 papers reporting medical news on 10 Websites were in-dexed and verified by machine indexing.The extraction accuracy was 0.34 and the recall rate was 0.30, showing that the strategies can be used for automatic extraction of key words from medical news.

OBJECTIVE To investigate the status of nosocomial infection in community health services and offer a scientific basis for nosocomial infection control.METHODS Totally 5738 outpatients were investigated retrospectively for nosocomial infection in community.RESULTS The most frequently nosocomial infection sites were lower respiratory tract,and next upper respiratory tract and urinary tract(2131,1045 and 934,respectively).The major reasons of causing the nosocomial infection were irrational usage of antibacterial drugs(39.0%),invasive procedures(31.0%) and using glucocorticoids(10.0%).Most of the pathogenic bacteria of the nosocomial infection were Gram-negative and the next were Gram-positive and fungi.74.4% of the pathogens were resistant to most of antibioties.CONCLUSIONS Alzeimer′s disease patients in the community health centers are popular and susceptible to infection.
