Objective: To discuss the influence of the fine care for newborn with severe pneumonia (SPIN) combining with respiratory failure (RF). Methods: 60 cases of SPIN with RF were selected and divided into the observation group and the control group. 28 cases of SPIN with RF in the observation group were received fine care observation group after treatment, in which 16 cases were male children and 12 cases were female children. The ages of these children were from 10d to 28d day, and their average age was 18.26 + 4.16 d. The weight was from 2.4kg to 4.4 kg, and their average weight was 3.11 + / - 0.44 kg. 32 cases of SPIN with RF in the control group were received routine nursing, in which 14 cases were male children and 18 cases were female children. The ages of these children were from 10d to 28d and their age was (10 ~ 28) d. Their average age was (18.33 + 4.07) d. The weight was from 2.4kg to 4.4 kg, and their average weight was 3.08 + / - 0.46 kg. Then we analyzed espectively respectively on two groups of children with pH, arterial blood gas analysis index of oxygen partial pressure (PaO2), arterial partial pressure of carbon dioxide (PaCO2), respiratory rate (RR) and heart rate (HR) level and the total time of mechanical ventilation, the incidence of adverse circumstance and nursing satisfaction. Results: The observation group with pH, PaO2, PaCO2, RR and level of HR after fine care is superior to the control group, and the differences were statistically significant difference (t= 4.36, 3.83, 2.23, 12.11, 5.45; P <0.05). The total time of mechanical ventilation in the observation group was significantly lower than the control group, and the difference was statistically significant difference (t=7.63, P<0.05). The reintubation rate of the observation group was obviously lower than the control group and the difference was statistically significant (x2=3.83, P<0.05). Family satisfaction of nursing in the observation group was obviously higher than that in the control group, and the difference was statistically significant (x2=18.49, P<0.05). Conclusion: Fine care can effectively improve the SPIN with RF with blood gas analysis index, shorten the time of mechanical ventilation therapy, alleviate the pain and reduce reintubation rate. It has higher clinical value.

Objective:To investigate the expression and function of CD226 on NK s ubsets and its coexpression with other activation receptor and inhibition recept or on NK cells. Methods:The expression of CD226 on CD56 bright and CD56 dim NK subsets and coe xpress ion with CD16 and NKG2A in PBMC and MLC in the presence or absence of IL-2 or IL-15 were detected by double fluorescent staining and flow cytometry analysis. The level of IFN-? in the supernatants of PBMC culture and MLC treated with o r without IL-2 or IL-15 were evaluated by ELISA. 51Cr release assay w as employed to measure the specific lysis of NK cells killing target K562 cells. Results:CD226 was mainly expressed on CD56 dim NK subsets in PBMC. When s imulated by IL-2, CD226 expression was shifted to CD56 bright NK subsets, while IL-15 increased the subpopulation of NKG2A+CD226+double positive cell s. In MLC-generated NK cells, CD226 was mainly expressed on CD56 dim NK su bsets, and also shifted to CD56 bright NK subsets in the addition of IL-15 . Furt hermore, the percentage of CD16+CD226+和NKG2A+CD226+ subsets were increa sed when stimulated by IL-2 or IL-15. There was great increase in IFN-? lev el in the supernatants of PBMC culture in the presence of IL-2 or IL-15, but no difference in the supernatants of MLC treated with or without two cytokine s. Moreover, the cytotoxicity of NK cells in PBMC and MLC were greatly enhanced by IL-2 or IL-15. Conclusion:CD226 is mainly expressed on CD56 bright NK subsets in IL-2 or IL-1 5 activated NK cells, and is coexpressed with CD16 and NKG2A preferentiatly, whi ch maybe involve in the modulation of cytotoxicity of NK cells based on the balance of coexpressed activation and inhibition receptors.

OBJECTIVE To investigate the effect of furanodiene(FDE),a diterpene derived from the medicinal plant Zedoary,on apoptosis of human gastric cancer MGC-803 cells induced in vitro. METHODS MGC-803 cells were treated with FDE 46.29~740.74μmol·L-1 for 24,48 and 72 h,and the cell viability was detected with MTT assay. Cell morphology was observed by light microscopy and Hoechst33342 staining. Flow cytometry was used to detect cell apoptotic rate and cell cycle. Rh123 staining and fluorescence probe DCFH-DA were employed to detect the changes in mitochondrial membrane potential (MMP) and reactive oxygen species(ROS). RESULTS MTT Results showed that FDE 46.29-740.74μmol · L-1 exhibited significantly higher cytotoxicity to gastric cancer MGC-803 cells. IC50 for MGC-803 of 24,48 and 72 h treatment was 347.91,257.41 and 101.01μmol·L-1,respectively. Treatment with FDE 92.58-370.32μmol·L-1 for 24 h also caused significant morphological changes in MGC-803 cells. AnnexinⅤ-FITC/PI double staining showed that the apoptotic rate increased after FDE 92.58-370.32μmol·L-1 treatment for 24 h(P<0.05). FDE enabled MGC-803 cell cycle arrest in S phase. DCFH-DA staining showed that FDE resulted in an increase in intracellular ROS levels(P<0.05) when PDE concentration was 370.37μmol·L-1(P<0.05). MMP decreased after FDE treatment when PDE concen?tration was 370.37μmol·L-1(P<0.05). CONCLUSION FDE Possesses potent tumor selected toxicity and can induce apoptosis of MGC-803 cells through cell cycle arresting,which is related to inhibition of DNA biosynthesis.

OBJECTIVETo compare clinical efficacy of anatomic locking plate and Gamma nail in treating unstable femoral intertrochanteric fractures with external wall fractures.

METHODSFrom June 2010 to June 2014,clinical data of 44 patients with intertroehanteric fractures associated with lateral wall fractures (type 31A2.2-3.3) followed more than 12 months,which treated with Gamma nail or anatomic locking plate,were retrospective analyzed. Sixteen patients were treated with anatomic locking plate, including 6 males and 10 females aged from 32 to 83 years old with an average of 56.5 years old. Twenty-eight patients were treated with Gamma nail including 17 males and 11 females aged from 26 to 87 years old with an average of 60.4 years old. Operative time, intraoperative fluoroscopy times, blood loss (intraoperative and hidden blood loss), hospital stays were observed and compared. PPMS and HHS scoring were used to evaluate postoperative clinical effect.

RESULTSAll patients were followed up from 12 to 24 months with an average of 16.2 months. Operative time in Gamma nail was shorter than anatomic locking plate; while blood loss( intraoperative and hidden blood loss) and intraoperative fluoroscopy times in anatomic locking plate were less than that of in Gamma nail. There was no significant meaning in hospital stays between two groups. Postoperative full weight-bearing time in anatomic locking plate was prolonged than Gamma nail. At the final following-up, PPMS in Gamma nail was 7.50 ± 1.78 and 6.82 ± 1.38 in anatomic locking plate, and there was no obvious meaning between two groups (t = 2.341, P = 0.132); there was no significant differences in HHS score between Gamma nail (83.25 ± 11.18) and anatomic locking plate (86.14 ± 12.36) (t = 1.923, P = 0.243). The incidence of complications in Gamma nail was less than anatomic lock-ing plate (P = 0.005).

CONCLUSIONAnatomic locking plate for intertrochanteric fractures with external wall fractures could avoid re-injury of external wall, especially for severe comminuted fractures, difficult for intramedullary nailing, and there was no significant meaning in hip joint function compared with Gamma nail, while postoperative incidence of complications was higher than Gamma nail, so early weight-bearing was not stress.

AIM:To study the visual acuity and refractive status of students pupils and middle school students in Shenzhen, and to provide a scientific basis for the prevention and control of myopia.
METHODS:A cluster sampling method was used to select five primary school students(6 737) and three junior middle school students(1 925) from Shenzhen. The visual acuity, anterior segment, fundus, eye position, and refractive status were measured. Information on associated factors for poor vision were also obtained using a questionaire. The risk factors of poor vision and the rate of myopia between grade or gender were analysed by Chi-square test.
RESULTS:The rate of poor vision was 67. 0%. Female, family history of high myopia, long time of continuous look near, short time of outdoor activities were the main risk factors. The rate of emmetropia, hyperopia, astigmatism and myopia were 15. 1%, 11. 3%, 11. 0% and 62. 6% respectively. Emmetropia, hyperopia and astigmatism incidenece rate decreased with age growing, but myopia incidence rate was increased. There were significant differences between adjacent two grades in myopia(χ2=7. 338-45. 018, P<0. 05 ) except the primary grade six and the junior grade one. There were significant differences between boys ( 61. 0%) and girls ( 65. 5%) in myopia(χ2=17. 180, P<0. 05).
CONCLUSION:The rate of poor vison is pretty high in students of Shenzhen aged between 5 to 16 years old, and myopia is the main reason. The development rate of myopia is increased with age. Early management of myopia may play an important role in controlling poor vision in students.

Objective:To explore the relationship between atrial fibrillation stroke risk score (CHA2DS2-VASc score) and short-term prognosis of aged patients with nonvalvular atrial fibrillation (NVAF)complicated ischemic cerebral stroke (ICS).Methods:A total of 206 aged NVAF+ ICS patients who hospitalized in our hosipital from Jun 2011 to Aug 2013 were selected.CHA2DS2-VASc score was used to perform stroke risk stratification,and patients were di- vided into low risk group (n=24,0 score),medium risk group (n=78,1 score)and high risk group (n=104,2~9 scores).Modified Rankin scale (mRS)was used to assess patients'prognosis on three months after onset.According to mRS score,patients were divided into good prognosis group (n=89,0~2 scores)and poor prognosis group (n=117,3~6 scores).Independent predictors for poor prognosis in three months were analyzed.Results:Compared with low risk group,there were significant rise in age,percentages of hypertension,diabetes mellitus (DM),heart failure,stroke and vascular disease history,scores of United States national institutes of health stroke score (NIHSS) in medium and high risk groups (P<0.05 or <0.01).Compared with good prognosis group,there were significant rise in age [(72.81±7.68)years vs.(81.56±8.03)years],percentages of hypertension (58.4% vs.71.8%)and stroke history (9.0% vs.29.9%),scores of NIHSS [(2.97±1.42)scores vs.(7.67±3.92)scores]and CHA2DS2- VASc [(1.70±1.63)scores vs.(4.03±2.53)scores]in poor prognosis group,P<0.05 or <0.01. Multi-factor Logistic regression analysis indicated NIHSS score (high risk:OR=1.78,95%CI:1.27~2.56,P=0.001 ), CHA2DS2-VASc scores (high risk:OR=3.24,95%CI:1.32~6.98,P=0.001)and age (high risk:OR=1.23, 95%CI:1.07~1.54,P=0.01)were independent predictors for poor prognosis on three months in aged NVAF +ICS patients.Conclusion:CHA2DS2-VASc score is related to early improvement of patients with NVAF + ICS;age,scores of NIHSS and CHA2DS2-VASc are independent predictors for poor short-term prognosis.

The study was purposed to investigate the effects of humanized recombined CD25 monoclonal antibody (rhCD25MAb) on activation and proliferation of T lymphocytes in vitro. Peripheral blood mononuclear cells (PBMNC) were incubated with phytohemagglutinin (PHA). Before or after T cell activation, the cells were cultured with or without rhCD25MAb or cyclosporine A (CsA) in vitro. After 72 hours incubation, the proliferation of lymphocytes was analyzed by MTT assay. The expression of CD3 and CD25 antigens on T lymphocytes were detected by flow cytometry. The levels of sIL-2R in the supernatants were determined with ELISA. The results showed that both rhCD25MAb and CsA could inhibit the proliferation of T lymphocytes significantly in concentration-dependent manner and CsA was more efficient than rhCD25MAb. Both rhCD25MAb and CsA could also decrease the levels of sIL-2R in the supernatant and inhibit the expression of CD25 antigen on T lymphocytes. The level of sIL-2R and the expression of CD25 on T lymphocytes decreases more profoundly in rhCD25MAb group. It is concluded that rhCD25MAb shows strong immunosuppressive activity both before and after T cell activation, suggesting that this agent may be useful in not only prophylaxis but also the treatment of acute graft-versus-host disease.
