With the development of modern medicine,to see a doctor is no longer a simple process of diagnosis or taking drugs.Human have deeply recognized medical science and health from a simple biomedical model to a social,psychological and biomedical model.On the one hand,people seek help from medical science.On the other hand,people fear that malpractice could occur.It has been in a love-hate mentality for people to seek medical and legal relief.In the new era,physician-patient relationship needs to be recognized again from medical staff,patients and legal angles.The combination of medicine and law is the requirement of development of the times.No matter how strong the law is,and no matter how much we hope the legislation is from strength to strength,moderation is still the virtues of the law.Medical perspective is still required in the examination of medical activity.

Objective To explore the effect of different frequencies interference of electoracupuncture on acute stress of C57BL/6 mice. Methods Thirty male C57BL/6 mice were randomly divided into model group,2Hz electroacupunture group and 100 Hz electroacupunture group.After interfering 7 days by electroacupuncture,all the mice were carried forced swimming tests and tail suspension test,and the immobility time in 5 minutes were taken down. Results The immobility time of forced swimming test and tail suspension test of 2 Hz eletroacupuncture group(32.00±14.73)s,(72.50±20.44)s was shorter than those of 100 Hz electoracupuncture group(145.60±34.62)s,(124.22±21.67)s( P <0.05); and the immobility time of 2 Hz eletroacupuncture group was shorter than that of model group(129.50±33.94)s,(142.23±20.05)s( P <0.05); but the immobility time of 100 Hz electroacupuncture group was no difference with that of model group( P >0.05). Conclusions The effect of 2 Hz eletroacupuncture could improve the behaviors of the acute stress of C57BL/6 mice and had the more effectiveness on anti-depression.

Extracellular matrix remodeling plays a role in the pathogenesis of variety of diseases.Among these extracellular proteinases,Cathepsin is a key member.In this review,the relationships between Cathepsins and many diseases associated with extracellular matrix remodeling is discussed.

Objective To evaluate the clinical efficacy of sodium tanshinone IIA sulfonate(STS)in the treatment of ad-vanced schistosomiasis. Methods Fifty cases with advanced schistosomiasis admitted to the Touzao Township Hospital of Dong-tai City during the period from November 2012 to November 2013 were treated with STS for 10 days,and the internal diameter of the portal vein,levels of ALT,AST,γ-GT,PIIIP,CIV,HA and LN were measured and compared before and after the adminis-tration of STS. Results The mean levels of all serological parameters except HA were within the normal range before STS treat-ment,while the highest positive rate was detected inγ-GT(26.0%)and HA(54.0%). Following the STS treatment,the mean lev-els of all parameters and the positive rates reduced,with the greatest reduction observed inγ-GT(36.7%)and HA(37.8%);how-ever,the mean HA level was still higher than the normal range. The mean internal diameter of the portal vein reduced from(10.5± 1.7)mm before the STS treatment to(9.8±1.3)mm after the STS administration,with a significant diffrtence(P<0.05). Conclu-sion STS appears effective in the treatment of advanced schistosomiasis.

The forced oscillation technique (FOT) is a noninvasive method for respiratory mechanics measurement. For the FOT, external signals (e.g. forced oscillations around 4-40 Hz) are used to drive the respiratory system, and the mechanical characteristic of the respiratory system can be determined with the linear system identification theory. Thus, respiratory mechanical properties and components at different frequency and location of the airway can be explored by specifically developed forcing waveforms. In this paper, the theory, methodology and clinical application of the FOT is reviewed, including measure ment theory, driving signals, models of respiratory system, algorithm for impedance identification, and requirement on apparatus. Finally, the future development of this technique is also discussed.

Objective To investigate the clinical distribution of carbapenem-resistant Enterobacteriaceae(CRE)strains separated in this hospital and the situation of its production of carbapenem enzyme.Methods The production of carbapenem enzyme by CRE strains was confirmed by using modified Hodge test,the situation of the production of metallo-beta-lactamases by CRE strains was screened by using imipenem-EDTA double-disk synergy test,and the clinical distribution of CRE strains was retrospectively ana-lysed.Results 37 strains of CRE isolated in this laboratory were screened by using instrument method and verified by using disk diffusion (K-B)method.It showed an increasing trend from 2012 to 2014 in the amount of CRE strains.In terms of bacterial spe-cies,K.pneumonia(1 6 strains)was the main kind of carbopenems-resistant strains,followed by E.coli(6 strains),Ser.marcescens(6 strains)and E.cloacae(4 strains).CRE strains were mainly isolated from geriatric ward and intensive care unit(ICU).Sputum,u-rine and blood specimen were key sources of CRE strains.Modified Hodge test confirmed that 36 strains of CRE were the strains that can produce carbapenemase,including 4 strains of K.pneumonia,3 strains of E.cloacae,and 1 strain of E.asburiae,and strains producing metallo-beta-lactamases were confirmed by using imipenem-EDTA double-disk synergy test.Conclusion Elderly patients with underlying diseases are susceptible population of CRE hospital infection and are primary preventive targets.The principal mechanism of carbapenem-resistant CRE strains in this hospital is the production of carbapenemase and production of metallo-β-lac-tamases in a small number of strains.

BACKGROUND:Traditional bladder repair methods have many problems such as damage to normal organ function and many postoperative complications. Tissue engineering technology provides a new way for bladder repair.
OBJECTIVE:To explore the feasibility of constructing tissue-engineered bladder with vascular endothelial growth factor (VEGF) nanoparticle-bacterial celulose (BC) composite scaffold with rabbit lingual epithelial cels andtonguemuscle cels.
METHODS:Rabbit lingual epithelial cels andmuscle cels were successively implanted onto the BC scaffold (control group) and VEGF-BC scaffold (experimental group). Six rabbits were taken to make bladder defect models and randomized into two groups: experimental group implanted with VEGF-BC scaffold carrying autologous lingual epithelial cels andtonguemuscle cels,and control group implanted with BC scaffold carrying autologous lingual epithelial cels andtonguemuscle cels. Specimens were taken from the two groups for urographic evaluation and histological examination at 3 months after implantation. Meanwhile, the urodynamic tests were performed.
RESULTS AND CONCLUSION:The experimental group showed the relatively complete bladder, and the control group showed a smal-area filing defect of the bladder. The maximum bladder capacity and bladder compliance in both two groups were decreased after implantation, especialy significantly in the control group (P< 0.05). In the control group, it failed to build a complete epithelial cel layer, and the muscle layer and microvessels were formed a little. In the experimental group, the complete epithelial cel layer was formed, and a larger amount of muscle layers and capilaries appeared. These findings indicate that the VEGF-BC scaffold carrying lingual epithelial cels andtonguemuscle cels can be used to construct thetissue-engineered bladder.
