Persister cells are dormant or slowly grown variations in microbial populations .They are highly tolerant to antibiot-ics but the tolerance are not inherited as the genetic resistance , when persisters are inoculated to fresh medium , most bacteria are still susceptive to antibiotic , while only a small fractiont become persisters again .Persisters are believed to be closely related to clinic bio-film forming and the recurrence and recalcitrance of chronic infections .Different persisters have been found in Escherichia coli , Pseud-omonas aeruginosa , Staphyococcus aureus , Mycobacterium tuberculosis , Candida albicans and so on , and a few mechanisms about per-sisters formation have been studied .This article reviews the current progresses of research methods and achievements on persisters from different levels .

Objective To discuss the application effects of fast track surgery treatment in hysterectomy. Methods 120 patients underwent hysterectomy. They were randomly assigned to two groups,namely,fast track sur-gery group(60 cases) and control group(60 cases ). two groups underwent separately fast track surgery mode and tradi-tional mode therapy. To observe the duration of passing flatus, the hospital stay, the aching time, the complication rate after operation between two groups. Results All patients got recovery. The duration of passing flatus(29.2±7.9) h,the aching time 96.7% (58/60)、the hospital stay( 3.9±2.5 )d of fast track surgery group were significantly shorter than the duration of passing flatus (50.3±15.8 ) h 、the aching time 8.3% (5/60)、the hospital stay (6.7±2.8 ) d of control group( allP<0.01 ). there was no severe complication in two groups. Conclusion Fast track surgery treat-ment mode could accelerate postoperative rehabilitation of hysterectomy patients. It shoud be popularized.

Idiopathic pulmonary fibrosis is divided into chronic progression stage and acute exacerbation stage according to progression of disease;early,middle and late stage according to onset time and clinic symptoms.It is considered that the etiological factors of idiopathic pulmonary fibrosis are repeated suffering of exogenous pathogen,environmental pathogen, deficiency of lung and kidney.The basic pathological products are blood stasis and phlegm turbid,the key point of pathopoiesis is that phlegm and stasis hides deeply and stagnated,the pulmonary collaterals are blocked.In addition,the evolutions of pathogenesis during its different stage are discussed.

Wearable devices bring us an innovative human-computer interaction which plays an irreplaceable role in enhancing the users' ability in environmental awareness, acquirements of their own state and "ubiquitous" computing power. Since 2013, wearable devices have quickly appeared around us. In this article we classify most of the wearable devices which have been appeared in the markets or reported in the literature according to their functions and the positions where they are worn. Furthermore, we review the technologies related to wearable devices, such as sensing technology, wireless communication, power manager, display technology and big data. At last, we analyze the challenges which the wearable devices will face in near future, and look forward to development trends of wearable devices.

Objective To investigate the effect of independent on duty assessment in the process of new nurse standardized training.Methods Totally 64 new nurses graduated in 2010 were set as the control group.Totally 68 new nurses graduated in 2011 were named as the observation group.The nurses in the control group received hospital standardized training,on the basis of the hospital standardized training,the observation group received independent on duty training.One year later,all nurses participate in the assessment of independent on duty organized by nursing department and the evaluation results were analyzed.Results The score of emergency response capacity of the observation group was significantly higher than that of the control group.Conclusions The implementation of the independent on duty assessment can strengthen the results of standardized training and promote emergency ability of new nurses,and effectively improve the ability of new nurses in clinical work.

OBJECTIVE: To study the approach for developing a rat model of pulmonary fibrosis induced by bleomycin (BLM). METHOD: Different doses (7, 6, 5, 3.4, 2, 1 mg/kg) of bleomycin A5-saline were infused into the rats' lung in bleomycin-treated group through tracheal intubation, and rats in sham-operated group were infused with same volume of saline. The living state and lung pathology of the rats were observed. The author deeply studied the condition of the rats in 1 mg/kg bleomycin-treated group, and the changes of body weight and lung pathology were observed. Lung quotient, the content of transforming growth factor beta1(TGF-beta1) and platelet-derived growth factor (PDGF) in serum were measured on the 14th, 28th and 45th day of the experiment. RESULTS: The study demonstrated that infusing large doses of bleomycin A5 quickly through tracheal intubation had a high mortality, and infusing 1 mg/kg quickly could successfully develop an animal model of pulmonary fibrosis. Compared with the sham-operated group, fibrosis was appeared obviously in the rats' lung in 1 mg/kg bleomycin A5-treated group after 14 days of experiment, diffuse fibrosis was appeared after 28 days of experiment, and the fibrosis became more severe after 45 days of experiment. The body weight of the rats in bleomycin-treated group was declined after 3, 7 and 14 days of experiment as compared with the sham-operated group (P<0.01). Twenty-one days after the experiment, the body weight was declined too, but there was no significant difference between the bleomycin-treated group and the sham-operated group (P>0.05). Lung quotient was increased 14, 28 and 45 days after the experiment (P<0.01), the level of serum TGF-beta1 began to increase since 28 days after the experiment (P<0.05, P<0.01), and the level of serum PDGF also increased gradually 45 days after the experiment (P<0.05). And the mortality rate of 1 mg/kg bleomycin A5-treated group was lower than those of the other doses of bleomycin A5-treated groups. CONCLUSION: A rat model of pulmonary fibrosis can be duplicated successfully by infusing 1 mg/kg bleomycin A5 quickly through tracheal intubation.

Objective To investigate the change of plasma marinobufagenin (MBG) level and the expression of its receptor Na+-K+-ATPase (NKA) in renal biopsy specimens of chronic glomerulonephritis (CGN) patients. Methods Twenty-eight CGN patients and 14 healthy people were enrolled in the study. The plasma MBG concentration was measured by competitive inhibition ELISA system. Immunofluorescence and immunohistochemistry staining were applied to detect the expression of NKA in renal biopsy specimens of 28 CGN patients and analyzed by semi quantitively. Results Compared with healthy controls, CGN patients had significant lower plasma MBG concentration [(0.579±0.214) nmol/L vs (0.715±0.154) nmol/L, P＜0.05], without further significant difference between CGN patients with hypertension and with normal blood pressure [(0.595±0.231) nmol/L vs (0.557±0.197) nmol/L, P＞0.05]. Meanwhile, proximal tubular staining of NKA was decreased compared with normal controls. The NKA positive staining area of the CGN group was lower than that of normal controls [2.1% (0.5%-6.2%) vs 5.6% (3.5%-10.8%), P＜0.01] and correlated with 24-hour urinary sodium excretion (r=0.551, P＜0.01).Conclusion Decreased plasma MBG level and its receptor expression on proximal tubules may play a role in the regulation of sodium in CGN.
