Objective To describe the status of publication papers on nursing of 47 grade three and first-class hospitals in Henan province from the year of 1991 to 2014 and provide valuable reference basis for the relevant departments to make policy. Methods The methods of literature metrology was used to analyze the amount, journals, key words distribution and other information of the 12 422 articles with the keyword 'nursing', which were included by China National Knowledge Infrastructure (CNKI) and Wanfang data, VIP database. Results The number of published articles of the investigated units was in the upward trend on the whole. But the number of annual published articles on the core periodicals was significantly lower than the total. The articles were mainly distributed on 3 nursing core journals, 5 non-nursing journals of Henan province, which were mostly for regional academic exchanges. 11 key words of nursing articles of Henan were the same as the nation but different for the sequence. Conclusions The grade three and first-class hospitals in Henan are in urgent need of the construction of systematic and standardized scientific research training system. The channel for the exchange of nursing academic needs to be widen. Clinical nursing research should be paid more attention to the characteristic field.

To evaluating the imaging features and the pathological basis of low grade malignant cystic mesothelioma of the peritoneum (LGMCMP). In 14 cases of LGMCMP, radiographic imaging (X ray, CT, and MRI) was reviewed, and diagnosis was established by pathology. The majority of the patients were middle aged women. The main symptoms were abdominal pain or discomfort. CT and MRI revealed solitary cystic masses in 3 of them, multiple cystic nodules in 5, and diffuse cystic nodules in 6. It is therefore concluded that X ray, CT, and MRI are helpful in revealing the characteristics of LGMCMP and confirm the diagnosis.

Objective To compare the effects of different administration routes and dosages of tropisetron on cisplatin-induced kaolin intake in rats.Methods Ninety-six healthy adult male Wistar SPF rats were randomly divided into 8 groups(n =12 each):intrathecal (IT) control group (group TC) and 3 tropisetron groups receiving IT tropisetron 10,20 and 30 μg,the volume of each group was 30 μl (group T10,T20,T30),intravenous(Ⅳ) control group (group IC) and 3 tropisetron groups receiving Ⅳ tropisetron 0.3,0.5 and 0.7 mg/kg respectively (group I0.3,I0.5,I0.7).In group TC and IC,normal saline 30 μl and 0.5 ml were injected IT and Ⅳ,respectively.All rats received cisplatin 3mg/kg by intraperitoneal injection at the time point of thirty minutes after administration,each rat weight,the daily food and kaolin intakes were detected at the time point of 48 hours after cisplatin administration.Results Compared with group Tc,each rat weight loss,the kaolin intakes were significantly decreased (P ＜ 0.05),and food intake dose was significantly increased in group T20 (P ＜ 0.05).Compared with group IC,each rat weight loss,the kaolin intakes were significantly decreased (P ＜ 0.05),and food intake dose was significantly increased in group I0.5 and I0.7 (P ＜0.05).There was no significant difference between group I0.5,I0.7 and group T20.Conclusions The kaolin intakes and the rat weight loss can be decreased by IT tropisetron,and the food take dose was increased meanwhile,and IT tropisetron 20 μg has equivalent efficacy to IV tropisetron 0.5 or 0.7 mg/kg.IT could be the new administration route of tropisetron.

Objective To evaluate the in vitro antifungal activity of 4 antifungal agents alone or in combination against Exophiala dermatitidis (E.dermatitidis) biofilms.Methods E.dermatitidis biofilms were prepared by using a modified 96-well plate-based method.The in vitro antifungal activity of amphotericin B,voriconazole,itraconazole and caspofungin alone or in combination against E.dermatitidis biofilms were investigated via the broth microdilution checkerboard technique.Results The sessile minimum inhibitory concentration ranges resulting in 50％ (SMICS0) and 80％ inhibition (SMIC80) of E.dermatitidis biofilms were all ＞ 32 mg/L for itraconazole,voriconazole and caspofungin,and the SMIC50 and SMIC80 ranges of amphotericin B were 1-2 mg/L and 4-8 mg/L respectively.The combination of amphotericin B with voriconazole showed synergistic inhibitory effects against E.dermatitidis biofilms,while the combination of amphotericin B with itraconazole or caspofungin,as well as the combination of voriconazole with caspofungin,revealed no synergistic effects.No antagonistic effect was observed in any of the combinations.Conclusion Amphotericin B appears more active against E.dermatitidis biofilms,and the combination with voriconazole can enhance the anti-biofilm effects against E.dermatitidis biofilms.

BACKGROUNDTo investigate the efficacy of EP regimen combined with split-course hyperfractionated accelerated irradiation for locally advanced non-small cell lung cancer.

METHODSThe treatment was composed of 3 cycles of combined chemoradiotherapy at 4-week intervals. Chemotherapy with cisplatin ( 30 mg/m²) and etoposide (60 mg/m²) was administrated intravenously on days 1-3, followed by radiotherapy on days 4-8. A course of radiotherapy consisted of 1.5 Gy per fraction, twice a day (3 Gy per day) for 5 consecutive days, for a total dose of 15 Gy. In the third cycle, additional irradiotherapy consisted of 2 Gy once a day was performed on days 11-15, for a total dose up to 55 Gy during 10 weeks. After three cycles, patients were given 2 additional cycles of chemotherapy with MVP regimen.

RESULTSOf the 43 patients, 12 had a complete remission and 22 a partial response, resulting in an overall response rate of 79.1%. Of the 152 chemotherapeutic cycles administrated, there were 40 during which grade III-IV toxicities occurred, mainly consisting of leukopenia and vomiting. The 1- and 2-year survival rates were 66.7% and 57.2%, respectively.

CONCLUSIONSEP regimen combined with split-course hyperfractionated accelerated irradiation is effective and well tolerated for advanced locally non-small celll lung cancer. It should be investigated further.

Objective:To evaluate the effect of jugular vein bulb pressure (JVBP) on postoperative cognitive function in elderly patients undergoing valve replacement-coronary artery bypass grafting under cardiopulmonary bypass (CPB).Methods:Ninety-two patients of both sexes, aged 65-75 yr, with body mass index of 18-25 kg/m 2, of American Society of Anesthesiologists physical status Ⅱ or Ⅲ, with New York Heart Association class Ⅱ or Ⅲ, were selected.All the patients underwent right internal jugular vein catheterization to monitor central venous pressure (CVP) and retrograde catheterization to measure JVBP.JVBP was recorded immediately after anesthesia induction (T 11), 10 min after CPB (T 12) and at the end of operation (T 13). The patients were divided into 2 groups according to JVBP: JVBP<12 mmHg group (group L) and JVBP≥12 mmHg group (group H). At T 11-13 and on 1st and 2nd days after operation (T 14, 15), heart rate, mean arterial pressure (MAP) and central venous pressure (CVP) were recorded, and blood samples from the jugular vein bulb were collected to determine the concentrations of S100β protein and matrix metalloproteinase-9 (MMP-9) in plasma and nerve specific enolase (NSE) in serum.Cognitive function was evaluated by Mini-Mental State Examination (MMSE) at 1 day before operation (T 21), 3 and 7 days after operation (T 22, 23) and 3 months after operation (T 24). Results:A total of 80 patients were included in this study, including 46 patients in group L and 34 patients in group H. Compared with those at T 11, CVP, JVBP, and concentrations of S100β protein and MMP-9 in plasma and NSE in serum were significantly increased at T 12 in group H, and CVP at T 13-15 and JVBP at T 12, 13 and concentrations of S100β protein and MMP-9 in plasma and NSE in serum at T 12-15 were significantly increased in two groups ( P<0.05). MMSE scores were significantly lower at T 22, 23 than at T 21 in the two groups ( P<0.05). Compared with group L, JVBP at T 12, 13, CVP at T 12-14 and concentrations of S100β protein and MMP-9 in plasma and NSE in serum at T 13 were significantly increased, concentrations of S100β prote in plasma were increased at T 12, MMSE scores were decreased at T 22-24, and the incidence of POCD was increased in group H ( P<0.05). JVBP was positively correlated with CVP, plasma S100β protein, MMP-9 concentration and serum NSE concentration, and the r values were 0.95, 0.56, 0.70 and 0.58, respectively ( P<0.05). Conclusion:Increased JVBP can decrease the postoperative cognitive function of elderly patients undergoing valve replacement-coronary artery bypass grafting under CPB, and the mechanism is related to blood-brain barrier damage.

As an effective treatment for cancer, chemotherapy not only removes tumor cells, but also produces obvious killing effects on proliferating cells, especially hematopoietic cells, resulting in bone marrow suppression after chemotherapy, and affecting the effects of chemotherapy drug treatment and treatment cycle. Therefore, starting from the aspects of hematopoietic microenvironment damage and hematopoietic stem cell aging, to explore the mechanism of myelosuppression after chemotherapy, which provides new ideas and theoretical support for the intervention and management of bone marrow suppression after cancer chemotherapy.

Objective To evaluate the in vitro effects of photodynamic therapy alone or in combination with antifungal agents on the apoptosis of planktonic and biofilm cells of Exophiala dermatitidis (E.dermatitidis).Methods The planktonic suspensions of E.dermatitidis were prepared,and the biofilms of E.dermatitidis were prepared via a modified 96-well plate-based methods.Planktonic and biofilm cells of E.dermatitidis were separately divided into several groups:antifungal agent groups treated with antifungal agents alone,photodynamic therapy group receiving photodynamic therapy alone,combination groups receiving photodynamic therapy followed by the treatment with antifungal agents,and blank control group receiving no treatment.These antifungal agents included amphotericin B,posaconazole,voriconazole and itraconazole.The concentrations of these antifungal agents were all 1 mg/L,and the treatment with antifungal agents lasted 2 hours.Terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assay was performed to detect the apoptosis of planktonic and biofilm cells of E.dermatitidis in all the groups.Results The antifungal agents and photodynamic therapy both affected the apoptosis of planktonic (both P ＜ 0.001) and biofilm cells (beth P ＜ 0.05) of E.dermatitidis.The apoptosis rates of E.dermatitidis planktonic cells in the control group,amphotericin B group,posaconazole group,voriconazole group and itraconazole group were 11.67％ ± 0.21％,13.30％ ± 1.78％,14.30％ ± 3.61％,14.51％ ± 1.91％and 36.17％ ± 4.00％ respectively.The apoptosis rate of E.dermatitidis planktonic cells was significantly higher in the itraconazole group than in the control group (P ＜ 0.05),but no significant differences were observed between the other 3 antifungal agent groups and control group (all P ＞ 0.05).The photodynamic therapy group also showed a significantly higher apoptosis rate of E.dermatitidis planktonic cells (41.37％ ±7.80％) compared with the control group (P ＜ 0.05).After the treatment with photodynamic therapy combined with amphotericin B,posaconazole,voriconazole or itraconazole,the apoptosis rates of E.dermatitidis planktonic cells were 29.23％ ± 6.71％,37.23％ ± 10.86％,43.57％ ± 6.42％ and 69.87％ ± 3.53％ respectively.Moreover,the photodynamic therapy + voriconazole group and photodynamic therapy + itraconazole group both showed significantly higher apoptosis rates compared with the voriconazole group and itraconazole group respectively (both P ＜ 0.05).The apoptosis rate of E.dermatitidis biofilm cells was significantly higher in the photodynamic therapy group than in the control group (32.00％ ± 0.43％ vs.25.30％ ± 1.31％,P ＜ 0.05),as well as in the photodynamic therapy + amphotericin B than in the amphotericin B group (P ＜ 0.05).Conclusion Photodynamic therapy combined with antifungal agents can markedly promote the apoptosis of planktonic and biofilm cells of E.dermatitidis.

To conduct the characterization of its pharmacokinetics in rats of nifedipine sustained-release pellets and to study the relationship between the pellets and CYP3A4 activity. A gradient HPLC method was developed to simultaneously determine 6β-hydroxycortisol and hydrocortisone. CYP3A4 activity of rats was quantified by urinary ratio of 6β-hydroxycortisol/hydrocortisone after intravenous injection of hydrocortisone as a biomarker. HPLC method was also developed to quantify the drug concentration in plasma of rats, and the studies of pharmacokinetics were performed after oral administration of single dose of two formulations: Nifedipine matrix sustained-release pellets and nifedipine tablet(using as control). The results showed that the ratio of ten rats was 0. 271±0. 129. cmax of nifedipine sustained-release pellets decreases by nearly 70%, tmax significantly increased by 400% and t1/2 and MRT significantly increased by 230% compared to control. Nifedipine sustained-release pellets had a significant sustained-release property compared to the control and CYP3A4 activity affected its pharmacokinetics behavior.

Objective To establish female and male bovine collagen-induced arthritis(CIA)models and compare the effects of gender differences on joint and extra-articular manifestations of the CIA model.Methods The CIA model was induced by injection of bovine type Ⅱ collagen and Freund's complete adjuvant into female and male SD rats.The general condition,arthritis index,foot swelling,serum proinflammatory factors and plasminogen activator inhibitor levels,spleen index,knee and ankle joint pathologies,right rear paw bone destruction,and pulmonary interstitial lesions were evaluated.Results The arthritis index of female CIA rats was significantly higher than that of male CIA rats on day 21 after initial immunization(P＜0.05),but no significant difference was found in the degree of foot swelling between the two groups at any time point(P＞0.05).Serum tumor necrosis factor α,interleukin-1β,and the spleen index of female CIA rats were significantly higher than those of male CIA rats(P＜0.05,P＜0.001).No significant difference was found in plasminogen activator inhibitor levels(P＞0.05).The scores of inflammatory cell infiltration and synovial hyperplasia in the knee and ankle pathologies of female CIA rats were significantly higher than those of male CIA rats(P＜0.05),and cartilage damage of the knee joint and bone damage of the right rear paw of female CIA rats were significantly higher than that of male rats(P＜0.05).Both male and female CIA rats showed pulmonary interstitial inflammatory cell infiltration and mild fibrosis,but the pulmonary interstitial lesions in females were more severe than those in males.Conclusions Female and male CIA models established in SD rats have arthritis and pulmonary interstitial lesions,but the lesion degree in female CIA rats is more serious.When using CIA models for RA-related research,attention should be focused on the effect of gender differences.
