Objective To observe the application of alkaline cleaning agent in disinfection and supply room cleaning of medical devices, to evaluate the cleaning quality. Methods The 800 contaminated medical instruments collected from February 2016 to February 2017 in municipal maternal and child health hospital were divided into control group (February 2016 to August 2016) and study group (September 2016 to March 2017 ) according to different time periods,with 400 pieces in each group.In the reference group, the instrument was washed with multienzyme detergent, and the study group was cleaned with alkaline detergent. The cleaning of 2 groups of instruments was observed and compared. Results The total excellent and good rate of instrument cleaning in the study group was 97.25％ (389/400), in the reference group was 89.50％(358/400), the difference between the two groups was statistically significant (P<0.05); the cleaning safety, practicality, economy, comprehensive score difference of the study group was significantly better than the reference group (P<0.05). Conclusion The effect of alkaline cleaning agent used in disinfection supply room cleaning medical instruments is remarkable, and the equipment residue and microorganism can be effectively eliminated, and the utility model has the advantages of high safety and low economic cost, and has the important practical value.

Objective To investigate the status of community type 2 diabetic patients with peripheral arterial disease,analyze the influencing factors and put forward nursing countermeasures.Methods 210 type 2 diabetic patients living in a community in Shanghai were enrolled in the investigation.ABI and arterial peak velocity were measured using Doppler blood flow detector,symptoms and signs of foot were assessed and related laboratory examinations,including HbA1c,HDL-C,LDL-C were tested.Results There were 49 cases of ABI ＜ 0.9.The proportion of abnormal color of foot skin,edema,abnormal pulsation of dorsal artery of foot and sense of coldness in group of ABI ＜ 0.9 were larger than group of ABI≥0.9.There was no statistical significance between the two groups in the pain at rest and intermittent claudication.Logistic stepwise regression analysis showed that age and LDL-C not up to the standard were risk factors of PAD and the peak of foot dorsal artery flow was a protective factor of PAD.Conclusions It's important to early screen for PAD and to adopt corresponding nursing measures on the basis of treatment.We hope to further prevent the development of PAD and effectively prevent diabetic foot.

Objective To identify differentially expressed proteins in keloid tissue and to explore the proteomic characteristics of keloid by utilizing capillary high-performance liquid chromatography (LC) and tandem mass spectrometry (MS).Methods Tissue specimens were obtained from the lesions of 5 patients with non-familial keloid and normal skin of 5 human controls.After extraction and in-solution digestion of proteins,the resultant peptides were separated and identified by LC-MS/MS.Label-free detection and quantitation of peptides were carried out by using the DeCyder MSTM software.Results A total of 570differentially expressed peptides were identified between non-familial keloid and normal tissue (all P ＜ 0.05),which correspond to 1221 proteins.A difference greater than 1.5 folds was observed in the expressions of 293 proteins,including 124 up-regulated and 169 down-regulated proteins in non-familial keloid tissue.Conclusion Differences exist in the expression of proteins between non-familial keloid and normal skin tissue.

Objective To know the advantages and disadvantages of problem-based learning from students'angle. Methods Interviewed 15 students by PBL scale and face to face interview,to know their ideas about problem-based learning,and then analyzed the results. Results PBL contributed to developing problem-solving skills,self-directed learning,team collaboration and extending professional knowl-edge. But it failed to show positive effect on students'learning motivation. Conclusions PBL has two sides on the outcomes of learning. Implementing PBL appropriately could gain the optimal effects.

Sixty cases of pseudobulbar palsy were treated by puncturing Shuigou (GV 26), Lianquan (GV 23), Fengchi (GB 20), Wangu (GB12), Yifeng (TE 17),Tongli (HT 5), Neiguan (PC 6) and Fenglong (ST 40)with the needling technique to refresh mind and open orifice, and by puncturing the retropharyngeal wall and palatine arch, plus training of swallowing function, the total effective rate reached 95.0%.

Objective To get a more comprehensive view of caregiving experiences, and describe the caregiver burden and the positive aspects of caregiving of family caregivers of senile dementia patients in community and to explore the relationship between the caregiver burden and the positive aspects of caregiving. Methods Totally 80 family community-dwelling caregivers of senile dementia patients in community were investigated by Caregiver Burden Inventory (CBI) and Positive Aspects of Caregiving (PAC) questionnaires. Results The score of CBI was 54.73 ± 13.15 and the score of PAC was 28.53 ± 5.37. The score of PAC was negatively correlated with the caregiver burden (r=-0.243, P<0.05). Conclusions The caregiver burden of the family community-dwelling caregivers of dementia patients is high and the positive aspects of caregiving is at middle level. Professional help and support should be provided to the family caregivers of dementia patients by the community health service centers on the premise that the caregiving experience is fully understood. Our aim is to reduce their burden, strengthen the caregiving skills and improve the positive aspects of caregiving simultaneously.

The national essential drug system is designed to solve the problem of covering hospital expenses with medicine revenue, and the problem of difficulty and high expense to see a doctor. This paper investigated whether the national essential drug system worked in three public community hospitals in Beijing. The result showed that the implementation of the program was now well underway, but left some problems. This paper put forward some suggestion for bidding of essential drug, improving the enthusiasm of the medical staff and improving the function of community hospitals.

Objective To establish age specific reference ranges of serum total prostatic specific antigen (T PSA) and to investigate the relationship between T PSA,free PSA (F PSA) and ratio of F PSA/T PSA(F/T) with age in benign prostatic hyperplasia (BPH) patients. Methods 913 consecutive cases were studied retrospectively.In all of them with the age ranged from 30 to 89, serum T PSA and F PSA levels were assayed.All the patients were suspected to be BPH or PCa,103 being diagnosed as PCa on biopsy under B ultrasound and the other 810 being BPH. Results The incidence rate of PCa was 11.3% in this group.Serum T PSA and F PSA levels were positively correlated with the age ( r=0.22,P

Objective To compare the serum PSA (T PSA and F/T PSA ratio) between patients of benign prostatic hyperplasia (BPH) and prostate cancer (PCa). Methods We studied retrospectively 810 cases of BPH and 103 cases of PCa consecutively from November of 1996 to June of 1999 and compared the differences of T PSA level and F/T ratio between these two kinds of diseases. Results In BPH patients,serum T PSA 10 ng/ml were 71.7%, 22.1 % and 6.2% respectively while these were 10.7%,17.5% and 71.8% in PCa patients ( P 10 ng/ml(0.110 ng/ml.
