Objective To understand the incidence and related risk factors of healthcare-associated infection(HAI)in neu-rological patients with cerebrovascular diseases.Methods The occurrence and risk factors of HAI in patients with cerebro-vascular diseases in a hospital between Jan and December 2013 were investigated and analyzed.Results Of 3 573 investiga-ted patients,214 had HAI,the incidence of HAI was 5.99%;the main infection site was respiratory tract (54.67%),fol-lowed by urinary tract (25.23%).Univariate analysis revealed that age,length of hospitalization,disturbance of conscious-ness,chronic obstructive pulmonary disease,diabetes mellitus,invasive procedures,application of antacids,and antimicro-bial prophylaxis were all related to the occurrence of HAI (P<0.05).Multivariate logistic regression analysis revealed that disturbance of consciousness,old age,invasive procedures,chronic obstructive pulmonary disease,and diabetes mellitus were independent risk factors for the occurrence of HAI (all P <0.05).Conclusion The incidence of HAI is high in hospitalized patients of the neurology department,there are multiple risk factors associated with HAI,it is necessary to take corresponding interventions for reducing the incidence of HAI.

OBJECTIVE:To guide rational use of Heamocoagulase agkistrodon for injection,and to provide reference for phar-maceutical care. METHODS:Treatment methods and outcome of 9 cases of allergic shock induced by Heamocoagulase agkistrodon for injection were retrieved from CNKI and VIP database during 2009-2015,and then analyzed statistically,based on one case of allergic shock induced by Heamocoagulase agkistrodon for injection in the Affiliated Hospital of Zhunyi Medical College. RE-SULTS:10 pationts with allergic shock induced by Heamocoagulase agkistrodon for injection mainly used the drug for hemostasis before and after surgery,heavy menstrual bleeding,etc.,with dose of 1 or 2 U. Route of administration included intravenous injec-tion and intravenous dripping. Allergic shock often occurred within 30 min after medication. CONCLUSIONS:The use of Heamoco-agulase agkistrodon for injection in some patients belongs to off-label drug use,and route of administration is different from that stated in package inserts. Allergic shock induced by Heamocoagulase agkistrodon for injection occurs rapidly;the drug should be used strictly according to package inserts and authoritative literatures;emergency plan should be developed before medication in or-der to guarantee the safety of drug use.

Objective To investigate the effectiveness of hyperthermia of different degrees in killing tumor cells and its influence on Na+ -K+ -ATPase activities in erythrocytes. Methods Cultured low differentiated stomach gland tumor cells (SGC-170) and large intestine gland tumor cells (LOVO) (1?106?ml-1 each) were mixed with concentrated RBCs respectively and incubated in warm bath of 37℃ , 42℃, 43℃ , 45℃ or 47℃ for 40 min respectively. After hyperthermic treatment tumor cells were isolated from RBCs using density gradient centrifugation and the live tumor cells were counted by typan staining. The isolated tumor cells were then cultured and the clone formation of tumor cells was checked. The cultured tumor cells were marked with 5-bromo deoxyuridine and DNA metabolism was examined. The Na+ -K+ -ATPase activities in RBC after hyperthermic treatment were also determined. Results The amount of tumor cells was significantly decreased by 40 min hyperthermic treatment in a temperature-dependent manner from 42-471 as compared with the control group (37℃) (P

Objective To examine if high-dose glucocorticoid has any cerebral protective effects aftercardiopulmonary resuscitation. Methods Twenty-one healthy mongrel dogs of both sexes weighing 10 .5-15 kg weresubjected to cerebral ischemia using Pittsburgh standard ventricular fibrillation-cardiac arrest (VF-CA) model. Theanimals were anesthetized with intraperitoneal pentobarbital sodium 30 mg?kg~(-1) and mechanically ventilated thertracheal intubation (V_T 15 ml?kg~(-1), RR 18-20 bpm). Right femoral vein was cannulated for fluid administration(lactated Ringer's solution 0. 15 ml?kg~(-1)?min~(-1)) and right femoral artery was cannulated for BP monitoring. ECGwas continuously monitored. The animals were randomly divided into 3 groups: group A received only routineresuscitation treatment (control, n = 5); group B received dexamethasone 5 mg?kg~(-1) (n = 8) and group Cmethylprednisolone 30 mg?kg~(-1) (n = 8) after successful cardiopulmonary resuscitation. 8 hours after resuscitationthe animals were anesthetized and three pieces of brain tissue were obtained from right parietal lobe for light andelectron microscopic examination and determination of dopamine (DA) and 5-hydroxy-tryptamine (5-HT) contentsusing high-performance liquid chromatography- electrochemical technique (HPLC- ECD ). Results The DA and 5 -HT contents in parietal lobe of cortex were significantly decreased in group B and C as compared with group A (P

Objective To assess the relationship between auditory evoked potential (AAI) index and plasma concentration of propofol administered by target-controlled infusion (TCI) in Chinese.Methods Ten ASA Ⅰ～Ⅱ tumor patients (5 males,5 females) scheduled for elective abdominal surgery under general anesthesia was enrolled in this study.Age ranged from 34 to 61 years,body weight from 52 to 79 kg and height from 155 to 178 cm.Radial artery was cannulated for blood sampling.The patients were premeditated with intravenous injection Midazolam 0.06 mg/L.Anesthesia was induced by fentanyl 2μg/kg,vecuronium 0.1 mg/kg and TCI of propofol which the target plasm concentration was set at 3 mg/L.After intubation,the target plasma concentration of propofol was adjusted at 1.7～2.5 mg/L.Vecuronium was continuous infusions at 2～3mg/h.Anesthesia was maintained with fentanyl-TCI of propofol-vecuronium and inhalation of 0.5 MAC isoflurane.The TCI system was composed of Base Primea company orchestra infusion pump using,the schnider pharmacokinetics model.ECG,Bp,HR,PETCO2,SpO2 and TETISO were monitored during anesthesia.Danmeter company A-line depth of anesthesia monitor recorded AAI index.Blood samples were taken at induction of anesthesia (To baseline),1,3,5,10,15,30,60 min (T1-7) and after cessation of infusion 10 and 20 min (T9-10).Plasma propofol concentration were determinated by fluorescence photometry.Results Compared with target concentrations,the measured concentrations of propofol were significantly lower during TCI(P＜0.05).There was negative correlation between AAI and plasma propofol concentrations(r=-0.818,P＜0.01).Conclusion On base of the Schnider pharmacokinetics model,the target propofol concentrations are not paralleled to plasma propofol concentrations which is descending with time prolongation.From negative correlation between AAI index and plasma propofol concentrations,AAI index will reflect indirectly plasma propofol concentrations.

Objective To evaluate the effect of Ganoderma lucidum on drug resistance of the cisplantin-resistant ovarian cancer cell line(A2780CP).Methods The A2780CP cells were randomly divided into control group and test group.The cells in control group and test group were incubated in culture media alone and in culture media containing Ganoderma lucidum 0.5 mg/ml for 48 h respectively.The resistance index(RI) of A2780CP was determined by WST-1 assay.The expression of Akt,Bcl-2 and p53 protein was measured by Western blot.Results The RI was significantly deeressed,the expression of Akt and Bcl-2 protein was down-regulated,while p53 protein expression was up-regulated in test group as compared with control group(P<0.05).Conclusion Ganoderma lueidum can reduce the resistance of A2780 CP cells to cisplantin by down-regulating the expression of Akt and Bcl-2 and up-regulating p53 expression in A2780CP cells.

Objective To investigate the outcomes of patients undergoing off-pump coronary artery bypass grafting (OPCABG) under morphine-fentanyl combined anesthesia. MethodsSeventy-two patients aged 41-64 yr undergoing OPCABG were randomly divided into 2 groups (n = 36 each): Ⅰ group morphine + fentanyl (group MF) and Ⅱ group fentanyl (group F). Anesthesia was induced with midazolam, etomidate, and vecuronium.Fentanyl 10-20 μg/kg was given iv when needed. The patients were mechanically ventilated after tracheal intubation. Anesthesia was maintsined with inhalation of 0.5%-2.0% isoflurane and intermittent iv boluses of vecuronium in both groups. Morphine 0.15 mg·kg-1·h-1 + fentanyl 8 μg·kg-1·h-1 were infused during operation in group MF, while in group F fentanyl 10 μg·kg-1·h-1 was infused. Morphine 0.75 mg/h was infused in group MF or fentanyl 10 μg/h in group F for postoperative analgesia after extubation. Recovery from anesthesia was assessed using a nine point (QoR) questionnaire. Pain was measured with VAS score and sedation with Ramsay sedation score ( 1 = fully awake, 6 = asleep, no response to verbal stimulus). The postoperative complications were recorded. ResultsQoR scores were significantly higher in group MF and in group F. The incidence of postoperative febrile reaction was significantly reduced in group MF. There was no significant difference in Ramsay sedation score and other postoperative complications between the 2 groups. ConclusionMorphine-fentanyl combined anesthesia is more beneficial for the prognosis in patients undergoing OPCABG compared with fentanyl combined anesthesia.

Objective:To study the clinical value of left ventricle Tei index in evaluating hemodynamics after interventional therapy of patent ductus arteriosus (PDA).Methods:From May 2017 to May 2019, 50 children with PDA who underwent interventional therapy (PDA group) and 27 healthy children (healthy control group) in Anhui Provincial Children’s Hospital were selected. The left ventricle Tei index, plasma brain natriuretic peptides (BNP), left ventricular end-diastolic dimension (LVDD), left ventricular ejection fraction (LVEF) were compared between 2 groups.Results:The left ventricle Tei index was not correlated with heart rate and age in 2 groups ( P>0.05). The left ventricle Tei index before operation in PDA group was significantly lower than that in healthy control group: 0.20(0.16, 0.25) vs. 0.27(0.20, 0.30), and there was statistical difference ( P<0.05). In PDA group, the left ventricle Tei index immediately, 3 d, 1 month and 3 months after operation was significantly higher than before operation: 0.38(0.29, 0.47), 0.32(0.26, 0.40), 0.30(0.27, 0.35) and 0.32(0.26, 0.37) vs. 0.20(0.16, 0.25), and there was statistical difference ( P<0.05); the plasma BNP immediately after operation was significantly lower than before operation: 288 (126, 433) ng/L vs. 582 (303, 1 675) ng/L, and there was statistical difference ( P<0.05); the LVDD 3 months after operation was significantly lower than before operation: (3.03 ± 0.54) cm vs. (3.38 ± 0.51) cm, and there was statistical difference ( P<0.05); the LVEF immediately after operation was significantly lower than before operation: (54.24 ± 6.09)% vs. (59.45 ± 5.93)%, the LVEF 1 and 3 months after operation was significantly higher than that immediately after operation: (63.18 ± 4.71)% and (65.46 ± 4.78)% vs. (54.24 ± 6.09)%, and there were statistical differences ( P<0.05). The left ventricle Tei index before operation was negatively correlated with inner diameter of PDA and plasma BNP ( r = -0.362 and -0.388, P = 0.013 and 0.009), and there was no correlation between LVDD and LVEF ( r = -0.192 and -0.283, P = 0.229 and 0.053); the differences of Tei index before operation and immediately after operation (ΔTei) was positively correlated with inner diameter of PDA ( r = 0.325, P = 0.030), and there was no correlation with BNP, LVDD and LVEF ( r = 0.234, 0.283 and -0.039, P = 0.126, 0.076 and 0.798). Conclusions:The left ventricle Tei index can quickly and accurately assess the change of hemodynamics after interventional therapy of PDA.

Objective To study the morphological changes of external eyes before and after epicanthoplasty combined with blepharoplasty and to explore a simple and efficient method to correct epicanthus. Methods A total of 120 eyes in 60 patients were operated on with the inverted L-sharp epicanthoplasty combined with double-eyelid blepharoplasty and the follow-up began 2 months after the surgery. The height and physiognomic length of the eyelid and the length and angle of the eyelash were measured and compared with preoperative meansurements, as well as the distance of the inner canthus. The ratios between the inner-canthus distance and the physiognomic eyelid breadth and the diameter of eyebrow and eye were also described. Results The contours of the eyelid fissure and the double-eyelid were natural and the surgical scare was seen unconspicuous 3 months after the operation. Changes in the palpebral fissure , the angel and length of the exposed eyelash were all significantly different by paired-sample t test (P < 0.01). The vertical and horizontal lines through the entocanthion and the vertical line through the gnomic ectocanthion combined with the horizontal line through the brow ridge formed a square structure. Conclusions This inverted L-shape epicanthoplasty combined with blepharoplasty may be effective in reconstructing the contours of the entocanthions as well as the shape of the double eyelids. It can also achieve better cosmetic effects in the proportional relation between the eyes and eyebrows. Therefore, it deserves clinical promotion.
