Objective To analyze the professional psychological pressure and coping style of male nursing students during different learning stage,and discuss effective ways to solve these problems in order to promote physical and mental health development of male nursing students.Methods Using coping style questionnaire and the professional psychological pressure of nursing students questionnaire to survey 102 undergraduate male nursing students from grade 2005 to 2008 of a nursing college of certain province.Results The professional psychological pressure of undergraduate male nursing students was moderate.Male nursing students of different grades had different professional pressure,in which male nursing students of secondyear had lower professional psychological pressure than other students.Manners they adopted to cope with pressure were mature,that is,the "problem-solving-help" approach,in which ways taken by second-year students were more than others.Conclusions Social bias to male nurses should be corrected.Professional psychological education should be carried out to relieve their mental pressure according to characteristics of students in different stage and direct them to realize role change.

Objective To determine whether chronic constriction injury (CCI) to sciatic nerve is associated with changes in the phosphorylation of CREB in dorsal root ganglia ( DRG) and superficial dorsal horn neurons of the spinal cord.Methods Thirty-two adult female SD rats weighing 230-270 g were randomly divided into 4 groups (n = 8 each): Ⅰ blank control;Ⅱ sham operation; Ⅲ CCI 2w and Ⅳ CCI 4w. The animals were anesthetized with intraperitoneal pentobarbital 40 mg?kg-1. Right sciatic nerve was exposed and 4 ligatures were placed on the right sciatic nerve at 1 mm interspace with 3-0 silk suture. Paw withdrawal threshold to mechanical stimulation (von Frey filament) applied to plantar surface ( MWT) and paw withdrawal latency to thermal stimulation (radiant heat) (TWL) were measured before operation (baseline) and 14 days (group Ⅰ,Ⅱ and Ⅲ) or 28 days (group Ⅳ) after nerve ligation. The animals were killed the next day and the L4,5 segment of the spinal cord and L5 dorsal root ganglion were removed for determination of expression of phosphorylated-CREB-immuno-reaction(pCREB-IR) using immuno-histochemistry. The pCREB-IR cells both in DRG and superficial dorsal horn neurons were quantified and analyzed. Results The animals developed mechanical and thermal hyperalgesia on the 14th day after CCI (in group CCI 2w) . The hyperalgesia was greatly attenuated on the 28th day after CCI. Interestingly enough the animals in sham operation group (Ⅱ) also developed mechanical hyperalgesia to some extent on the 14th day after operation. The number of pCREB-IR cells was significantly increased in the ipsilateral L5 DRG and superficial dorsal horn in group Ⅲ(CCI 2w) as compared to sham operation group ( P

Objective To compare the differences between college students and undergraduate students in terms of the evaluation of demonstration experimental teaching and analyze the influencing factors.Methods A questionnaire survey was conducted among 272 college students and 344 undergraduate students doing experimental study.Both stratified sampling and convenience sampling methods were used.Results The results showed that compared to the undergraduate students,the total score level of the evaluation,the teaching way,the teaching effect and the comprehensive evaluation of the college students was much lower.However,there were no significant differences between them in the evaluation of curriculum.Conclusions A few corresponding measures should be adopted by nursing schools and teachers to improve the quality of nursing experimental teaching.

The relation between patent applications and published papers in hospitals of Guangdong Province since 2000 on China Intellectual Property Network was analyzed , which showed that the quality and quantity of patents were lower in hospitals of Guangdong Province than in those of Shanghai and Beijing , the quality of patents was re-lated with the medical service level in hospitals, the patent applications were centralized in large class A hospitals of Guangzhou , and inventive patents were those of medical preparations .Suggestions were thus put forward for hos-pitals of Guangdong Province to improve their awareness of patent application, the quality of patents, transformation of patents, cooperation with patent service organizations, research of patent application, and balance of patent dis-tribution in different areas.

Objective To investigate β-lactamase gene and class 1 integron gene from 60 clinical Acinetobacter baumannii isolates.Methods The minimal inhibitory concentrations (MICs) for 16 antibiotics widely used were determined using the standard broth microdilution method.The β-lactamase gene,class 1 integron gene and adeB gene were determined by PCR and then sequenced.Results Fifty-three strains of the 60 A.baumanii isolates were multi-drug resistant.OXA-23 gene was detected positive in six A.baumanii isolates,which were all resistant to more than five antimicrobial agents including carbapenem and showed high resistance to many antibiotics.Thirtyeight strains earring PER-1 gene showed higher resistance to cephalosporins than those without this gene (P＜0.01).Class 1 integron gene was positive in 45 strains,which exhibited significantly higher multiple resistance than those without this gene (P＜0.01).Twenty-five strains carrying both class 1 integron and PER-1 genes had a markedly higher multiple resistance (P＜0.01),but not in resistant level,compared to the 7 strains without these two genes.Conclusion Class 1 integron and β-lactamase gene may be the causes of muhidrug-resistance of A.baumanii.The strains carrying OXA-23 gene always showed multiple and high resistance to several antibiotics,so effective measures must be taken to control the epidemic of these strains.

Objective:To investigate the prognostic value of platelet volume indices (PVIs), neutrophil/lymphocyte ratio (NLR) and the combination of these parameters for the neurological function of acute ischemic stroke (AIS) patients after intravenous thrombolysis.Methods:From January 2016 to January 2019, the data of 147 AIS patients with intravenous thrombolysis in the Emergency Department of Peking University People's Hospital who met the diagnostic criteria of AIS were retrospectively analyzed. The patients were divided into two groups according to modified rank in scale (MRS) score: MRS≤2 and MRS≥3. The general information, past medical history and laboratory examination results of each group were compared. Logistic regression analysis was used to analyze the risk factors of poor prognosis of neurological function in AIS patients with thrombolysis.Results:NLR ( OR=1.045, 95% CI: 1.032-2.350, P=0.032), mean platelet volume (MPV) ( OR=4.212, 95% CI:1.074-16.513, P=0.039), MPV×NLR/PLT ( OR=5.711, 95% CI: 1.342-24.298, P=0.018), platelet distribution width (PDW) ( OR=1.015, 95% CI: 1.001-2.372, P=0.032), and NIHSS score ( OR=1.266, 95% CI: 1.111-1.443, P<0.01) were related with poor prognosis neurological function of AIS patients with intravenous thrombolysis. Conclusions:MPV, NLR, MPV×NLR/PLT PDW and NIHSS scores are the risk factors for poor prognosis of neurological function in AIS patients with thrombolysis. MPV×NLR/PLT can predict the neurological severity of AIS after 3 months.

Objective To investigate the clinical efficacy of multi-functional fire needling plus auricular plaster therapy for moderate to severe acne vulgaris.Methods One hundred and fifty patients with moderate to severe acne vulgaris were randomly allocated to treatment and control groups, 75 cases each. Both groups were first given bloodletting at Ear apex and Helix 4. Then the treatment group received multi-functional fire needling plus auricular plaster therapy and the control group, auricular plaster therapy alone. The symptom and sign score was recorded in the two groups before and after treatment. The clinical therapeutic effects were compared between the two groups.Results There was a statistically significant pre-/post-treatment difference in the symptom and sign score in the two groups (P<0.01). There was a statistically significant post-treatment difference in the symptom and sign score between the two groups (P<0.05). The total efficacy rate and the cure and marked efficacy rate were 98.6% and 88.7%, respectively, in the treatment group and 93.2% and 60.8%, respectively, in the control group. There was a statistically significant difference in the cure and marked efficacy rate between the two groups (P<0.05).Conclusion Multi-functional fire needling plus auricular plaster therapy is an effective way to treat moderate to severe acne vulgaris.

Aim To study the inhibitory activities of potential new anti-influenza virus agents,3-O-β-chaco-triosyl pentacyclic triterpenoids against the entry of H5N1influenza viruses.Methods Three target com-pounds were designed and synthesized structurally re-lated to the lead compound 3-O-β-chacotriosyl dioscin derivative (1 )with inhibitory activities against H5N1 influenza viruses.The inhibitory activities of these tar-get compounds were tested at a cellular level pseudo vi-rus system targeting H5N1 influenza viruse entry.Re-sults All the compounds 1 a,1 b and 1 c showed po-tent inhibitory activities against the entry of A/Thai-land/Kan353/2004 pseudo virus into the target cells, of which compound 1 b showed the best inhibitory activ-ity with an IC50 value of (1.25 ±0.22)μmol·L-1. Conclusion The SARs analysis of these compounds indicated that replacement of the aglycone moiety of compound 1 with pentacyclic triterpenoids could in-crease antiviral activity.Different types of pentacyclic triterpen as aglycone residue had the significant influ-ence on the inhibitory activity (1 b >1 c >1 a),sug-gesting ursane type of triterpenes was superior to the two other kinds of triterpenes as aglycone residue.
