Relations between doctor and patient are basic and important human relation in medical practice.Because of some reasons,the relations appear tense status in our country,moreover the market economy flourishingly develops,as the result of medical organizations suffering more and more existent pressure.It is an important subject faced for people,especially for medical worker,to righly think the existed defects,and set up the mutual action between doctor and patient.

Objective To understand the molecular epidemiology characteristics and its drug resistance of methicillin-resistant Staphylococcus aureus (MRSA) in the urban area of Jilin and to provide important basis for guiding the clinical medication and prevention of the MRSA infection. Methods One hundred and three strains of MRSA from July 2013 to July 2014 in the urban area of Jilin were selected. The polymerase chain reaction (PCR) technology and multiple polymerase chain reaction were used to detect mecA gene and Staphylococcus chromosomal cassette mec typing (SCCmec) genotype of MRSA. The drug sensitivity test for 13 kinds of clinical common antibacterial drugs were detected by using the K-B method. And the source of the strains were analyzed. Results The results of SCCmec genotype of MRSA showed that SCCmecⅢtype were 62 strains, accounting for 60.2%;SCCmecⅡtype were 39 strains, accounting for 37.9%; failing to parting were 2 strains,accounting for 1.9%. Drug susceptibility test results showed that all of 103 MRSA strains were resistant to cefoxitin, cefazolin, penicillin and benzene, and drug resistance rate was 100.0%. The resistant rate to erythromycin, levofloxacin, ciprofloxacin, tetracycline, gentamicin and rifampin were 96.1%, 93.2%, 95.1%, 91.3%, 90.3%and 55.3%receptively;the resistant rate to sulfamethoxazolewas was only 1.9%;and the resistant strains to vancomycin and teicoplanin were not detected. The top three department of the distribution of the strains source were department of neurosurgery (31.1%), ICU (19.4%) and burn plastic surgery (17.5%). Conclusions The SCCmecⅢtype is the main MRSA epidemic strains, and SCCmec type II is a minor epidemic strainin the urban area of Jilin. The antibiotic resistance of MRSA is a serious problem with multiple drug resistance, but MRSA is sensitive to vancomycin and teicoplanin.

Lumbar intervertebral disc herniation clinical symptoms and signs are very complicated, lumbocrural pain is the most characteristic clinical symptoms,and show the site (range or area), intensity, nature, evolution, influence factors and adjoint symptoms and so on has certain characteristics and rules. Among them, the dermatomal pain, kinesthetic dysesthesia, dynamic changing pain and lesions segment vertebral side deep tenderness are the most impotent characteristics and rules of pain, therefore, can be regarded as the main basis of clinical diagnosis of the disease, and also the core content of this article.

Premature ejaculation (PE) is a common male sexual disorder with an incidence rate of 20-30%. Recent clinical trials have demonstrated that phosphodiesterase type 5 inhibitors (PDE5i), as the first-line drug for erectile dysfunction (ED), can improve ejaculatory function probably by acting on the peripheral and central adrenergic nerves. The possible action mechanisms of PDE5i may involve lessening of the central sympathetic output, modulation of the contractile responses from the vas deferens, seminal vesicles, prostate and urethra, induction of peripheral analgesia, and prolonging of the total erectile duration, increasing the confidence of ejaculation control, and reducing the post-ejaculation refractory time. This review discusses the possible mechanisms and clinical application of PDE5i in the treatment of PE.

Pain is common clinical symptoms of lumbocrural, but the etiology, pathology, sites (range or area), intensity, nature, evolution situation and influence factors of pain has some certain characteristics and rules. These differences particularly were regarded as the primary and important basis or clues for the clinical diagnosis and differential diagnosis of related diseases. A series of exclusive diagnosis for similar symptoms is premise of diagnosis of lumbar intervertebral disc protrusion. Ideas and methods of differential diagnosis of lumbar intervertebral disc herniation can help the diagnosis and identification.

Objective The studies on tissue culture and cytological observations of leaf explants of Curculigo orchioides were conducted in order to provide the basis for the rapid propagation of C. orchioides. Methods Young leaf explants of C. orchioides were cultured on MS basal media. Differences in the callus induction and plantlet regeneration rate were observed by different light treatment as well as chemical factors like different phytohormones, casein hydrolysate (CH), and activated charcoal (AC) concentrations. Paraffin method was used to cytological observation. Results For callus induction of leaf explants of C. orchioides, dark treatment gave better results compared to light treatment; among the media tested, the suitable phytohormone combinations were 2.0 mg/L 2, 4-D or 6-BA 1.5 mg/L+2, 4-D 2.5 mg/L, and 300 mg/L CH+0.2% AC was good for plantlet regeneration from leaf explants. The callus from leaf explants mainly originated from midrib. The parenchyma cells near epicuticle of midrib firstly were initiated to division. Then the parenchyma cells of vascular bundle sheath and mesophyll cells on each side of vascular bundle were also divided to form callus. The buds developed on the peripheral parts of the calli, but the roots developed in the regions deep within the calli. Conclusion Tissue culture of young leaf explants of C. orchioides can make the propagation of C. orchioides rapid.

Objective:To find out the key demand and connection point of health quality education for students of different stages by analysis of their health quality characteristics and the main contribution path, and then explore strategies to improve health quality. Methods:The stratified random cluster sampling method was carried out to select the sample population in Hangzhou. The variance analysis, curve fitting and multivariate linear regression analysis were used to analyze health quality characteristics and the main contribution path. Results:The health quality of pri-mary school students was best;the difference in quality between college students and junior high school students was not statistically significant ( P>0. 05 );and high school students had the worst health quality. The high school stage is the weakest link of health quality education. The order of the health education path and the means for improving the health quality of college, high school, and primary school students differ. With the improvement of students’ lev-el, the students that require physical quality promotion gradually decreases; the moral quality demand remains sta-ble;and the psychological quality and social adaptation ability present the tendency of a gradual increase. Conclu-sion:Student health quality shows a tendency to decreases with the rise of learning phase. The education departments should foster health consciousness and habits for students, form a healthy lifestyle behavior and ways of thinking for high school students, shape healthy personalities to improve health literacy and social adaptation abilities for college student, which is the key strategy for promoting the health quality of all-round development of the students and a-chieve the primary education goal of “health education”.

Objective To develop a highly sensitive and accurate time-resolved immunofluorometric assay (TR-IFMA) for measurement of Dickkopf-1(DKK-1),as a novel serologic biomarker for lung cancer. Methods The study constructed a two-manoclonal-antibody "sandwich"-type assay and the sensitivity, within run CV and between run CV and accuracy were evaluated. Serum DKK-1 concentrations were measured by TR-IFMA in 120 healthy controls, in 72 benign lung disease patients, and in 212 lung cancer patients before surgery. The association between serum DKK-1 levels and clinicopathological features were evaluated. Results A standard curve for DKK-1 TR-IFMA had been developed with good sensitivity (0.08 μg/L). Both within run CV and between run CV were less than 6.5%. Accuracy studies, parallelism and precision data were determined and all found to be satisfactory. The validity of DKK-1 assay was confirmed by the good correlation between the results obtained by TR-IFMA and commercial ELISA (r=0.972, P=0.01). The serum levels of DKK-1 were higher in lung cancer patients 31.93(79.47-18.03) μg/L than in benign lung diseases 15.25(18.41-11.49) μg/L and in healthy controls 13. 90( 16. 91-11.02) μg/L DKK-1 levels were significant associated with the presence of distant metastases, as well as lymph node metastases and TNM stage, but not with patients' age, gender and tumor histology. At the cutoff of 22.63 μg/L, the diagnostic sensitivity, specificity, accuracy, positive predictive value and negative predictive value of the TR-IFMA for lung carcinoma were 68.4%, 92.2%, 82.1% ,90.6% and 72.5%. Diagnostic sensitivity and accuracy were higher for small cell carcinoma than for non-small cell carcinoma (70.7% vs 69.5% and 85.6% vs 80.7%, respectively). Conclusions A highly sensitive and reliable TR-IFMA for DKK-1 has been developed. The determination of serum DKK-1 levels may be useful for diagnosis and tumor staging of lung cancer.
