Objective To understand the occurrence of healthcare-associated infection(HAI) in intensive care units (ICUs) in secondary and above hospitals in a province, and provide basis for HAI management.Methods HAI management quality control center in a province performed targeted monitoring on HAI in ICUs in secondary and above hospitals in a province from July 1, 2010 to June 30, 2015.Results ICUs in 176 hospitals were monitored, the incidence of HAI in ICUs for 6 consecutive years was 7.23％, case incidence of HAI was 9.72％;incidence of HAI showed a decreased trend in 6 years(P<0.001).The adjusted rate of HAI per 1 000 patient days in the general hospital ICUs was higher than that of special hospital ICUs (4.30‰ vs 3.53‰).Incidence of HAI in surgical ICUs and general ICUs were both relatively higher, adjusted rates of HAI per 1 000 patient days were 4.79‰ and 4.21‰ respectively.Respiratory tract, urinary tract, and bloodstream infection were major HAI in ICUs, accounting for 68.64％, 14.45％, and 10.09％ respectively, the utilization rates of central venous catheter, ventilator, and urinary catheter were 49.86％, 39.16％, and 81.95％ respectively, incidence of three catheter-associated infection were 1.74‰, 13.77‰, and 2.08‰ respectively, incidence of three catheter-associated infection decreased year by year (P<0.001).The utilization rates of ventilator, central venous catheter, and urinary catheter in different ICUs were not correlated with the incidence of infection(all P>0.05).A total of 36 223 strains of pathogens were isolated, the top 6 isolated pathogens were Acinetobacter baumannii(22.77％), Klebsiella pneumoniae (11.96％), Pseudomonas aeruginosa(11.94％), Staphylococcus aureus (8.08％), Candida albicans (5.63％), and Escherichia coli(5.55％).The isolation rates of carbapenem-resistant Klebsiella pneumoniae showed a increased tendency for 6 years(P<0.05).Conclusion Continuous targeted monitoring on HAI in ICUs, regular analysis on risk factors for HAI, and timely implementation of intervention measures can effectively decrease the incidence of HAI.

OBJECTIVE To comprehend the changes in the spectrum of clinically isolated pathogenic bacteria and their drug resistance,and to analyze their tendency.METHODS Totally 5746 pathogenic bacteria isolated from clinical samples of the inpatients in our hospital during 1997-2004 and their drug resistance was statistically(analyzed).RESULTS Most of clinically isolated pathogenic bacteria were Gram-negative.The detected rate of Gram-positive bacteria tended to rise,while the detected rate of fungi obviously increased year after year.Gram-positive cocci and Gram-negative bacilli were resistant to commonly used antibacterials in different degrees,(especially) to ampicillin.The sensitive rate of Gram-positive bacteria was high to vancomycin,while the sensitive rates of Escherichia coli and Klebsiella pneumoniae to imipenem were high.CONCLUSIONS The structure of(nosocomial) infection(pathogens) and their drug resistance patterns are changing continuously.It should be(emphasized) to inspect(bacterial) tolerance in order to select antibacterial reasonably.

Objective To evaluate the value of Compas technique( computed optimun method for profile angle of singht,Compas) in displaying intracranial aneurysms. Methods DSA images of 31 cases of subarachnoid hemorrhage diagnosed by CT were studied. The DSA images in routine A-P and Lateral projections were compared with the images obtained by Compas technique in the same equipment. Results 23 of 31 were diagnosed as intracranial aneurysms by Compas and confirmed by operation, while only 5 were diagnosed definitely with routine A-P & Lateral projections. The other 18 studies were discovered as blurred margin of the artery but indefinite for the diagnosis of aneurysms. There is a statistical difference between the two methods. ?~2=14.93,P

Objective To evaluate the effect of dexmedetomidine on brain injury in the patients undergoing cardiac surgery with cardiopulmonary bypass (CPB).Methods Eighty patients of both sexes, aged 18-64 yr, with body surface area of 1.6-2.0 m2, with left ventricular ejection fraction＞30％, of American Society of Anesthesiologists physical status Ⅱ or Ⅲ (New York Heart Association Ⅱ or Ⅲ), scheduled for elective cardiac surgery with CPB, were equally and randomly divided into control group (group C) and dexmedetomidine group (group D) using a random number table.Before induction of anesthesia, dexmedetomidine was given as a bolus of 1 μg/kg over 10 min followed by an infusion of 0.5 μg · kg-1 · h-1 throughout the surgery in group D, and the equal volume of normal saline was given in group C.After induction and before skin incision (T0) , at 30 min after beginning of CBP (T1) , at 30 min after the end of CBP (T2) , at the end of surgery (T3) , and at 24 and 72 h after surgery (T4.5) , blood samples from jugular bulb were drawn for determination of serum concentrations of tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), IL-10, S-100β protein and neuron-specific enolase (NSE).Results Compared with group C, the serum concentrations of TNF-α and S100β at T1-3 and IL-6 and NSE at T1.4 were significantly decreased, and the serum concentrations of IL-10 at T1-4 were increased in group D (P＜0.05).Conclusion Dexmedetomidine given as a bolus of 1 μg/kg over 10 min followed by an infusion of 0.5 μg · kg-1 · h-1 throughout the surgery can reduce the brain injury in the patients undergoing cardiac surgery with CPB, and the mechanism is related to inhibited inflammatory responses.

A fast,simple and sensitive high performance liquid chromatographic (HPLC) method has been developed for determination of 10α-methoxy-6-methyl ergoline-8β-methanol (MDL,a main metabolite of nicergoline) in human plasma.One-step liquid-liquid extraction (LLE) with diethyl ether was employed as the sample preparation method.Tizanidine hydrochloride was selected as the internal standard (IS).Analysis was carried out on a Diamonsil ODS column (150 mm × 4.6 mm,5 μm) using acetonitrile-ammonium acetate (0.1 mol/L) (15/85,v/v) as mobile phase at detection wavelength of 224 nm.The calibration curves were linear over the range of 2.288-73.2 ng/mL with a lower limit of quantitation (LLOQ) of 2.288 ng/mL.The intra- and inter-day precision values were below 13％ and the recoveries were from 74.47％ to 83.20％ at three qtality control levels.The method herein described was successfully applied in a randomized crossover bioequivalence study of two different nicergoline preparations after administration of 30 mg in 20 healthy volunteers.

Objective To compare and observe the clinical effects of microscopic evacuation of intraeranial hematoma and small bone flap approach mierosurgical operation in treatment of hypertensive cerebral hemorrhage.Methods From June 2008 to June 2010,116 cases of patients with hypertensive cerebral hemorrhage were classified into two groups with 58 cases in each by random digits table.Group A was treated with microscopic evacuation of intracranial hematoma and group B was treated with small bone flap approach microsurgical operation.The clinical efficacy and neurological impairment Scores were observed and compared between the two groups.Results The total effective rate in group A[87.9%(51/58)]was significantly higher than that in group B[72.4%(42,58)](P<0.05).After treatment 14 d and 28 d,the neurological impairment scores in group A were (22.1±6.2).(12.6±3.3)scores and in group B were (23.5±6.7),(18.6±5.1)scores.Compared with pre-treatment[group A:(41.9±8.1)scores;group B (41.7±7.9)scores],after treatment l4 d and 28 d,the neurological impairment scores in two groups were significantly decreased(P<0.05).Moreover,After treatment28 d,the neurological impairment scores in group A were significantly lower than those in group B(P<0.05).Conclusion Both microscopic evacuation of intracranial hematoma and small bone flap approach microsurgical operation are effective methods in hypertensive cerebral hemorrhage,but microscopic evacuation of intracranial hematoma can enhance the effect and improve the neurological function.

Objective To investigate the effects of autologous blood withdrawal-reinfusion on the perioperative coagulation function in patients undergoing cardiac surgery with cardiopulmonary bypass (CPB ) . Methods Eighty-four ASA physical status Ⅱ-Ⅳ patients ,without impairment of coagulation function ,scheduled for cardiac surgery with CPB ,were equally and randomly divided into 2 groups using a random number table :autologous blood withdrawal-reinfusion group (group ABWR , n= 44 ) and control group (group C , n= 40 ) . Decreased coagulation function was diagnosed based on the following two criteria :laboratory standard of decreased coagulation function and clinical signs .After anesthesia and before the beginning of operation (T1 ) ,at 5 min after heparin was reversed with protamine (T2 ) ,at the end of operation (T3 ) and at 24 h after the end of operation (T4 ) ,venous blood samples were obtained to measure the blood routine and parameters of coagulation function . Blood routine included the red blood cell (RBC ) , hemoglobin (Hb ) , hematocrit (Hct ) , platelet count , and plasma fibrinogen concentration (Fib) .The parameters of coagulation function included thrombelastography (TEG) variables and prothrombin time (PT ) ,activated partial thromboplastin time (APTT ) ,international normalized ratio (INR ) , and activated clotting time (ACT ) . The volume of intraoperative blood loss , amount of mediastinal drainage at 6 and 24 h after operation , consumption of tranexamic acid and heparin during operation , and consumption of fibrinogen after operation ,and requirement for transfusion of allogeneic RBCs ,fresh frozen plasma (FFP) and platelet during operation and within 24 h after operation were recorded .The development of decreased coagulation function during operation and within 24 h after operation .Results Compared with group C , perioperative consumption of allogeneic RBCs were decreased ,reaction time (R) measured by celite-activated TEG was increased at T3 (P<0.05) ,and no significant change was found in the blood routine index ,incidence of decreased coagulation function ,volume of intraoperative blood loss ,amount of mediastinal drainage ,consumption of tranexamic acid and heparin , and postoperative consumption of fibrinogen in group ABWR ( P> 0.05 ) . Conclusion Autologous blood withdrawal-reinfusion provides similar effects on coagulation function with allogeneic blood transfusion ,and does not increase the development of decreased coagulation function in patients undergoing cardiac surgery with CPB .

ObjectiveTo investigate the effects of acupuncture on neuromuscular block of vecuronium and analgesia under general anesthesia.MethodsNinety ASA Ⅰ or Ⅱ patients,aged 29-80 yr,weighing 50-80kg,scheduled for laparoscopic chotecystectomy,were randomly divided into 3 groups (n =30 each):acupuncture at acupoints combined with general anesthesia group (group A),acupuncture at non-acupoints combined with general anesthesia group (group B) and general anesthesia group (group C).Bilateral Hegu (LI4),Neiguan (PC6),Zusanli (ST36),yanglingquan (GB34),and Quchi (LI11) acupoints were selected in group A.In group B,the points adopted were the midpoints between the meridians in which the acupoints were selected in group A and the adjacent meridians on the lateral side,at the level of selected meridian points correspondingly.Electric stimulation was started from 15-30 min before anesthesia induction and continued until the end of operation.Anesthesia was induced with iv injection of fentanyl,propofol and vecuronium and maintained with intermittent iv boluses of fentanyl and vecuronium.All the patients received patient-controlled intravenous analgesia after operation.The effect time,onset time,clinical duration and recovery index of vecuronium,consumption of anesthetics during operation,and consumption of fentanyl for postoperative analgesia and postoperative adverse reactions were recorded.Results Compared with group C,the elinical duration was significantly prolonged,the consumption of anesthetics during operation and consumption of fentanyl for postoperative analgesia were significantly reduced,and the incidence of nausea was significantly decreased ( P ＜ 0.05 ),while no significant changed was found in the effect time,onset time,and recovery index in group A ( P ＞ 0.05).Compared with group B,the amount of fentanyl consumed during and after operation was significantly reduced in group A ( P ＜ 0.05 ).ConclusionAcupuncture can prolong the clinical duration of vecuronium,and enhance the analgesic efficacy during and after operation under general anesthesia.

Objective To investigate the pathologic morphology and immunohistochemical phenotypes of sarcomatoid carcinoma(SC) of the fallopian tube.Methods One case of SC of the fallopian tube was studied under the light microscopy for morphology.Immunohistochemistry was used to detect the expression of CK,EMA,S-100,Desmin,SMA,Leu-7,CD68,actin,and Vimentin in SC tissues.Pathologic features and biological behaviors of SC were analyzed in combination with the review of literature.Results Microscopically carcinomatous and sarcomatous elements co-existed.Usually the sarcomatous element formed the bulk of the lesion.In the sarcomatous tissues,there was no distinguishable bone,cartilage,rhadomyosarcoma,etc. Immunohistochemically the strong expression of CK7,EMA and Vimentin,and the partial expression of S-100,SMA,Leu7,CD68 and actin were detected.Conclusion SC of the fallopian tube is lack of specific symptoms,and its preoperative diagnosis is difficult.B-ultrasonography,CT and MRI are helpful to the staging of SC.Final diagnosis of SC depends on pathological examination and immunohistochemistry.SC is rare,and undergoes blood metastasis in early stage.Prognosis of SC is worst.Early detection of SC is the key to improve the prognosis.
