Objective To explore the effect of evidence-based nursing on improving the compliance of chronic obstructive pulmonary disease (COPD) patients with noninvasive positive pressure ventilation. Methods Forty-five patients hospitalized in the first half of the year were assigned as control group and another 45 patients hospitalized in the second half of the year were as experiment group. The control group was treated with traditional nursing methods. In the experiment group, a nursing panel was set up to analyze the causes of noncompliance of COPD patients with noninvasive positive pressure ventilation and gave care to the patients based on the analyses. The two groups were compared in terms of adverse reactions and the compliance with treatment. Result The rates of compliance with treatment and adverse reactions such as fear and anxiety , the man-machine confrontation and flatulence in the experiment group were significantly lower than those of the control group obviously (P<0.05). Conclusion The evidence-based nursing can reduce the incidence of adverse reactions , and enhance the compliance of COPD patients with noninvasive positive pressure ventilation effectively.

Objective To investigate the diagnosis value of p16 combined with Ki67 protein in cervical lesions.Methods Totally 1 542 women with previous liquid-based cytology smear result of abnormality underwent a colposcopy-directed biopsy excision procedure.Biopsy specimens were detected by p16 and Ki67 immunostaining alongside hematoxylin and eosin (H&E) staining.A four-semiquantitative class was used to describe the immunohistochemical results.Results Biopsy results revealed 1 542 women included 473 women with negative for dysplasia (NEG),629 women with cervical intraepithelial neoplasia (CIN) Ⅰ,206 women with CIN Ⅱ,206 women with CINⅢ and 28 women with cervical squamous cell carcinoma (SCC).The averageage of this study population was 34.47 years.CINs mainly occurred in women aged 20-29 years and 30-39 years.The positive rates of p16 in NEG,CIN Ⅰ,CIN Ⅱ,CINⅢ and SCC were 15.22％,60.25％,98.06％,99.51％,100.00％ respectively,and the positive rates of Ki67 were 12.05％,63.12％,96.12％,98.06％,100.00％ respectively.p16 expression and Ki-67 expression significantly increased with disease progression (p16:r =0.758,P =0.000 ; Ki67:r =0.773,P =0.000).Expression level of p16 was positively related with Ki-67 (r =0.774,P =0.000).The positive expression rates of p16 and Ki-67 of NEG were significantly lower than those of CIN and SCC (p16:x2 =1 127.46,P =0.000;Ki67:x2 =1 316.85,P =0.000).The positive expression rates of p16 and Ki-67 were markedly higher in CIN Ⅰ than those in CINⅡ,CINⅢⅢ and SCC (p16:x2 =500.19,P =0.000;Ki67:x2 =603.23,P=0.000).Conclusion Women aged 20-39 years are key subjects for cervical cancer screening.p16 and Ki67 immunohistochemistry is important in the ancillary diagnosis of cervical lesions.

Objective To investigate the clinical efficacy of fire needling in treating endometriosis.Method Fifty-eight endometriosis patients were randomly allocated to treatment and control groups. The treatment group received fire needling at specific points. The treatment was given at one week before menstruation until the end of it, twice a week, three months as a course. The control group took gestrinone 2.5 mg from the first day of menstruation, twice a week, for three consecutive months. The therapeutic effects were evaluated in both groups at three months after the end of treatment.Result The cure rate and the efficacy rate were significantly higher in the treatment group than in the control group (P＜0.05). The pregnancy rate was also higher in the treatment group than in the control group (P＜0.05).Conclusion Fire needling treatment for endometriosis has the advantages of good therapeutic effect, high cure rate and no influence on pregnancy.

Objective To observe effect of using ambroxol to humidify of airway during mechanical ventilation to treat severe pneumonia in infants,and to explore dynamic changes of respiratory mechanics.Methods Sixty-five infants with severe pneumonia need ventilator treatment according the diagnosis criterion were divided into 2 groups by random digits table method:experimental group (33 cases) and control group (32 cases).Experimental group was used ambroxol and control group was used 0.9％ sodium chloride,each 2 ml intratracheal instillation,and then took the balloon pressurized oxygen 30 s,followed by ventilator,after 24 h.Changes of respiratory mechanics indexes were observed before and after treatment,including:mean airway resistance,lung dynamic compliance,work of breathing,airway plateau pressure.Respiratory mechanics values were recorded before and after treatment.Results After treatment for 24 h,the index in experimental group were better than those in control group.Mean airway resistance were (0.68 ± 0.04) cmH2O/ (L·s) and (0.57 ± 0.05) cmH2O/ (L·s),1 cmH2O =0.098 kPa,lung dynamic compliance were (3.17 ± 0.81) ml/kPa and (2.56 ± 0.69) ml/kPa,work of breathing were (0.54 ± 0.08) J/L and(0.41 ± 0.06) J/L,airway plateau pressure were (2.23 ± 0.58) cmH2O and (2.12 ± 0.63) cmH2O.There were significant differences (P ＜ 0.05).The mechanical ventilation time in experimental group was significantly shorter than that in control group [(64.08 ± 13.92) h vs.(79.57 ± 19.64) h] (P ＜0.05).Conclusion Airway humidification using ambroxol can better treat severe pneumonia,reduce airway resistance and improve alveolar ventilation,shorten time on the machine.

Objective: To investigate the effect of mitoxantrone (MIT) on calreticulin (CRT) expression in B16 cells, and to observe the immune effect of B16-membrane antigen vaccine highly expressing CRT on B16 tumor-bearing mice. Methods: The expression of CRT on membrane of B16 cells was detected by immunofluorescence after treatment with different concentrations of MIT. B16-implanted mouse model was established, and the growth of B16-implanted tumors and CRT expression in B16-implanted tumor tissues were observed after treatment with different concentrations of MIT. Membrane antigen vaccines from both normal B16 cells and MIT-treated B16 cells were prepared, and mice were immunized before B16 cell implantation. The infiltration of immune cells into B16 tumor tissues and the ratios of CD4~+ and CD8~+ T cells in the spleen of B16 tumor-bearing mice were examined by immunohistochemistry and flow cytometry, respectively. Results: Flow cytometry results showed that MIT dose-dependently increased CRT expression on B16 cell membrane, with CRT expression in control and high dosage MIT groups being (29.40±3.57)% and (72.20±2.94)% (P<0.05), respectively. MIT also increased CRT expression in B16 tumor tissues, with those in the control and high dosage MIT groups being 3.21±1.37 and 9.17±1.06 (P<0.05), respectively. MIT effectively inhibited the growth of B16 tumors (P<0.05). Compared with normal B16 cell membrane antigen vaccine, the vaccine highly expressing CRT increased the numbers of DCs and T cells in B16 tumors tissues and the ratios of CD4~+ and CD8(+) T cells in the spleen (P<0.05). Conclusion: MIT can increase CRT expression on membrane of B16 cells. B16-membrane antigen vaccine highly expressing CRT can enhance the infiltration of DCs and T cells in melanoma, thus improving the immune effect of B16-membrane antigen vaccine.

Objective To explore the clinicopathological characteristics in atypical endometrial hyperplasia patients. Methods A retrospective study was carry out on 79 cases with atypical endometrial hyperplasia patients admitted to Department of Gynecology, Peking University People's Hospital from Mar.2007 to Jul. 2010. All patients were divided into two groups, hyperplasia group (merely atypical endometrial hyperplasia, 49 cases, 62%) and cancerization group (atypical endometrial hyperplasia accompanying endometrial carcinoma, 30 cases, 38%). Results The mean age of 79 cases were (50 ± 11) years old ,while they were (50 ± 10) and (51 ± 11) years old for hyperplasia group and cancerization group, there were not difference (P = 0.994). The gravidity and delivery frequencies were also not differently between two groups. The rates of complicated other diseases were 47% (23/49) and 43% (13/30), which was not significantly different (P = 0.755). The body mass index (BMI) of cancerization group was higher than that of hyperplasia group [(27.9 ± 5.4) vs. (25.2 ± 2.9) kg/m2, P = 0.024]. There were 50% (15/30) and 31% (15/49) menopause cases in two groups, respectively. Among them there were 13/15 and 8/15 cases showed vaginal bleeding. Among premenopausal patients, there were 12/15 and 68% (23/34) showed abnormal vaginal bleeding, but there were not significantly different between two groups (all P ＞ 0.05). The uterine cavity mass found by ultrasonography in the cancerization group patients was more than that in hyperplasia group [73% (22/30) vs. 51% (25/49), P = 0.050]. There were 23 cases (29%), 44 cases (56%) and 12 cases (15%) were diagnosed by dilatation and curettage (D&G), hysteroscopy and hysterectomy, respectively. The rates of diagnosing atypical endometrial hyperplasia by D&G and hysteroscopy were 87 % (21/23) and 93 % (41/44), respectively. The rate of diagnosis of canceration were 6/12 and 12/16, respectively. While, the rate of missed diagnosis of canceration in the atypical endometrial hyperplasia patients by D&G and hysteroscopy were 6/13 and 19% (4/21) ,respectively. Which all did not shown significantly different (P ＞ 0.05). Conclusion Hysteroseopy or D&G should be chosen on those peri-menopausal patients with abnormal bleeding, while those atypical endometrial hyperplasia patients with high BMI and uterine cavity mass diagnosed with D&G and ultrasonography should consider the possibility of canceration.

OBJECTIVETo explore the high risk factors of thrombosis in paroxysmal nocturnal hemoglobinuria (PNH). It has been reported that in Chinese patients with venous thrombosis, the mutation frequency in PROC c.574_576 del (rs199469469), PROC c.565C>T (rs146922325) and THBD c.-151G>T (rs1698852) was higher than that of normal controls, indicating its importance in thrombophilia pathogenesis.

METHODS142 patients with PNH diagnosed between 2009 and 2015 were enrolled in the study. Clinical data were analyzed and thrombophilia risk factors, such as the level of protein C, protein S, antithrombin III, APC resistance, blood fat, phospholipid antibody, were evaluated. Samples from patients and 100 normal controls were detected for the mutations of PROC c.574_576 del (rs199469469), PROC c.565C>T (rs146922325) and THBD c.-151G>T (rs1698852) by Sanger sequence.

RESULTSOf the 142 PNH patients, 21 (14.8%) patients had at least 1 episode of thrombotic event. Only 2 patients had arterial thrombosis and 19 patients had venous thrombosis. The median age of patients with thrombosis was 35 years old, similar to those without episode (40 years old, P=0.687). The ratios of males and females were 1.33 in thrombosis group and 1.57 in non-thrombosis group (P=0.728) , respectively. Patients with thrombosis had the same disease pattern compared with those without episode. Although there was no difference in the level of hemoglobin, WBC and PLT count, and LDH level between patients with thrombosis and those without episode, patients with thrombosis showed higher RBC, higher percentage of CD59(-) granulocytes and RBC, and Flaer(-) granulocytes compared with those without episode. The routine thrombophilia screening tests did not show any difference either between PNH patients and normal controls, or between patients with or without thrombosis. There were two mutations in rs199469469 and rs16984852 sites in patients with PNH, but the mutated patients did not have any thrombosis. Mutation rs146922325 was found in PNH patients. The mutation rate was similar between PNH patients and normal controls, thrombotic PNH and non-thrombotic PNH (P>0.05).

CONCLUSIONSCompared with non-thrombotic patients, PNH thrombotic patients have bigger PNH clone and higher RBC count. There are no differences among the routine thrombophilia factors and the three known venous eligible genes either between PNH patients and normal controls or between thrombotic and non-thrombotic PNH patients.
