Objective To summarize bacterial resistance in the women urine culture samples collected in 2012 from 557 first class hospitals and 232 second class hospitals in China.Methods Disc diffusion test, MIC test and E-test were used to detect the antimicrobial sensitivity of bacte-rial isolates from urine specimens.WHONET5.6 software was applied for analysis the bacterial sensitive data.Results A total of 80564 strains were collected in the survey period.The isolated rates of Escherichia coli (53.8%), K.pneumoniae (7.4%) and Enterococcus faecalis/Entero-coccus faecium ( 6.4%) occupied the top three positions.The resistant rates of Escherichia coli to carbapenems, β-lactam/β-lactamase inhi-bitor, nitrofurantoin, amikacin and fosfomycin was 0.9%, 3.7% -4.5%, 5.6%, 5.7%and 6.4%, respectively.The resistant rates of K.pneumoniae to carbapenems, β-lactam/β-lactamase inhibitor and amikacin was 5.0%-5.4%, 9.8%-10.6%and 8.8%, respectively.The resistant rates of Enterococcus faecalis to glycopeptides, nitrofuran-toin, fosfomycin and ampicillin was 1.0%-1.9%, 7.4%, 8.5% and 14.1%.There was no Enterococcus strain resistant to linezolid.Conclusion Escherichia coli is main species isolated from women urine sample.The resistance of the most species isolated from women urine culture to carbapenems,β-lactam/β-lactamase inhibitor, nitrofurantoin and fosfomycin are lower than 10%.There is no significant difference between the resistance of bacteria from first class and second class hospitals.

Objective To explore the experience and methods of neuro-endoscopy in minimally invasive treating intracranial diseases.Methods The surgery effect and complications of minimally invasive treatment under neuro-endoscopy on 52 patients with intracranial diseases,admitted to our hospital from October 2010 to March 2013,were retrospectively summarized; in these 52 patients,20 had pituitary adenoma,20 had hypertensive intracerebral hemorrhage,1 had intracranial hematoma followed arteriovenous malformation,2 had intracranial hematomas after brain injury,2 had cholesteatoma,2 had optic canal decompression,2 had cerebrospinal fluid rhinorrhea,1 had multi-separated subacute subdural hematoma and the last 2 had arachnoid cyst.Results Except for 1 patient having cholesteatoma appeared bleeding of the petrosalvein intraoperatively,which resulted in cerebellum hemorrhage following postoperative venous hemorrhagic infarction and unfavourable prognosis,the rest of the patients recovered well; in 20 patients having hypophysoma,15 (75％) achieved total resection of the pituitary adenoma,and no postoperative cerebrospinal fluid rhinorrhea occurred; in 23 cases of intracranial hematomas,22 were cleared satisfactorily,and the left one occurred rehemorrhage in one side but craniotomy hematoma removal was successfully performed again.The eyesight of 2 patients with optic canal decompression was improved obviously.The repair effects of 2 patients with cerebrospinal fluid leakage were very good without intracranial infection or recurrence.The 2 patients with arachnoid cyst recovered satisfactorily without other complications.One patient with multi-separated subacute subdural hematoma recovered with hematoma clear postoperative satisfactorily; and one patient with cholesteatoma postoperative recovered satisfactorily with tumor resection.Conclusion Neuro-endoscopy has many advantages such as exposed wide range,good deep lighting,minimally invasive and high efficiency in endoscopic transnasal transsphenoidal skull base surgery and intracranial hematomas removal.

OBJECTIVETo investigate the therapeutic efficacy of interferon (IFN) therapy and risk of long-term administration for chronic hepatitis C (CHC) patients who cannot tolerate the standard treatment.

METHODSForty-six CHC patients who had proven intolerant to standard treatments were treated with low-dose IFN (non-pegylated IFN: 60 to 300MIU QOD, or pegylated IFN: 50 to 90 mug/w) plus ribavirin (RBV; 0.6g to 0.9 g/d) for 72 weeks.

RESULTSForty-three (93.5%) of the patients were able to tolerate the long-term treatment with low-dose IFN plus RBV. Only three patients experienced severe side effects (low white blood cell and platelet counts) that required treatment withdrawal. The virology response rates over treatment time were: rapid virologic response (RVR): 10.9%; early virus response (EVR): 30.4%; 24 week virologic response: 45.7%; and, 48 week virologic response: 47.8%. B-sonographic imaging revealed that three patients experienced improved liver morphology through the treatment course. The patients who achieved RVR, EVR, or 24 weeks virologic response also attained higher 48 week virologic response. The 24 week virologic response had the strongest predictive value of good prognosis.

CONCLUSIONSOur study demonstrated that long-term treatment with low-dose interferon plus ribavirin is effective for patients who are otherwise intolerant to standard treatment. In these patients, low-dose IFN plus RBV can obtain a high virologic response rate at 48 week. Furthermore, the 24 week virologic response is sufficiently predictive of treatment success. As with any treatment regimen, it is important for healthcare workers to monitor the disease status and potential side effects throughout the course of therapy.

Objective To compare the clinical efficacy between total aortic arch reconstruction with open triple-branched stent graft placement and total aortic replacement combined with stented elephant trunk implantation for patients with Stanford A aortic dissection.Methods Patients with Stanford A aortic dissection treated with surgical treatment from January 2006 to May 2011 were included in this study.The patients were divided into two groups.Group Ⅰ (n =20) patients were treated by total arch replacement with stented elephant trunk procedure.Group Ⅱ (n =8 ) patients received open triple-branched stent graft placement. Echocardiography and aortic CT angiography were performed before and at 1 month after operation.Results Age,gender and disease severity were similar between the 2 groups ( all P ＞ 0.05 ).Operation was successful in all 28 patients.Cardiopulmonary bypass time,aortic cross clamp time,circulation arrest time and duration of ventilator assisted breathing were significantly longer; postoperative drainage volume and blood transfusion volume were significantly larger and hospitalization cost was significantly higher in group Ⅰ patients compared those in group Ⅱ patients ( all P ＜ 0.05 ). One month after operation,the maximum internal diameter of aorta was smaller than pre-operation in both group Ⅰ [ (30.2 ± 3.1 ) mm vs.(42.5 ±6.5)mm,P ＜ 0.05] and group Ⅱ [(31.5 ±2.5) mm vs.(44.1 ±7.3)mm,P ＜ 0.05].Conclusions Short-term procedural success rate was similar between the two groups.The total aortic arch reconstruction with open triple-branched stent graft placement procedure is simpler,shortens the operation time,reduces the blood transfusion volume and is more cost-effective compared to the classical aortic arch operation.

OBJECTIVE: To investigate the dynamics of the induction of S100beta in different parts of rat brain following the diffuse brain injury. METHODS: Immunohistochemistry and auto-image analysis were to determine the expression of astroglial S100beta after diffuse brain injury in rats. Forty rats were distributed into groups according to injury time of 30min, and2,4,12,24h, and 3,6 d after diffuse brain injury, and normal rats as control. RESULTS: The number of S100beta positive cells in the four areas increased significantly followed by a decrease, and then a further increase. The expression of S100beta could be detected increasing in 2h, and increased significantly in 4h, and it reached apex 12h after DBI, and decreased gradually to the level less than normal 3d, and returned to normal 7d following injury. In the postmortem injury groups, there were no significant changes in anti-S100beta immunoreactivities in four areas of brain compared to the control group. CONCLUSION The present study showed the time-dependent expression of S100beta is obvious following diffuse brain injury, and suggested S100beta be suitable as a marker for brain injury age determination.
