OBJECTIVE:To probe into the perioperative use of antibiotics in some clinical department of our hospital.METHODS:780 medical records of the patients(discharged from our hospital between Oct.2007 and Oct.2008)were sampled randomly for statistical analysis regarding the utilization of antibiotics.RESULTS:Of the 780 cases reviewed,778 cases(99.74%)received antibiotics versus 2 didn't.In terms of the application variety of antibiotics,Cephalosporins were predominantly used,followed in turn by penicillins and quinolones.289 cases used one kind of antibiotics,279 used two kinds and 210 used at least three kinds of antibiotics concomitantly.Only 19 cases received etiologic test and susceptibility test during antibiotic use.CONCLUSION:The perioperative use of antibiotics in some clinical departments of our hospital is somewhat irrational,thus monitoring on which should be tightened to promote their rational use.

Background The incidence of dry eye is gradually increasing,and the aging of population is one of factors.Researches showed that the change of tear film stability leads to shift of corneal refractive power, which probably affects the measurement of intraocular lens (IOL) power.The influence of dry eye on the calculation of IOL power is worth paying close attention.Objective This study was to investigate the influence of dry eye on the accuracy of IOL power calculation in age-related cataractous patients.Methods A non-randomized controlled clinical study was performed.Two hundred and sixteen eyes of 216 cataract patients were enrolled in Yanbian Eye Ear Nose and Throat Hospital from May 2013 to February 2014.The visual acuity, intraocular pressure, break up time of tear film (BUT),Schirmer Ⅰ test (S] t) and corneal fluorescein staining were examined in all the eyes,and then the patients were assigned to mild dry eye group (73 eyes), severe dry eye group (68 eyes) and non-dry eye control group (75 eyes).The axial length (AL) and anterior chamber depth (ACD) were measured using IOL Master for the calculation of IOL power and K value (corneal curvature).Phacoemulsification with IOL implantation was performed on all the eyes,and the refractive power was measured with KR 8100 automatic optometry 2 months after operation.The mean absolute refractive error (MARE) between actual refraction and predicted refraction was calculated, and percentage of eyes in different refractive error ranges was compared between the dry eye group and non-dry eye control group.The correlations of dry eye-related parameters with peroperative K value and refractive error were analyzed.This study was approved by the Ethics of Yanbian University,and written informed consent was obtained from each subject prior to entering the cohort.Results No significant differences were found in age, gender, AL,ACD and MARE among the mild dry eye group,severe dry eye group and non-dry eye control group (all at P＞0.05), and significant differences in BUT,S Ⅰ t and corneal fluorescein staining scores were found among these three groups (F=5.460,4.521,3.572, all at P＜0.05).The K values were (43.59± 1.39) , (44.66± 1.53) and (43.42± 1.32) D in the mild dry eye group,severe dry eye group and non-dry eye control group,and the K value in the severe dry eye group was significantly higher than that in the non-dry eye control group (P =0.012).The percentage of eyes with +0.50-+0.75 D deviation was significantly elevated(28.8％ versus 13.3％), and that with-0.50--0.75 D deviation was significantly declined (17.3％ versus 28.0％) in the dry eye group compared with non-dry eye control group (x2 =4.513 ,P=0.032;x2 =4.236,P=0.037).A negative correlation was found between BUT and K value (r=-0.204,P=0.011).Conclusions Dry eye affects the accuracy of the determination of IOL power.Compared with the preoperative refraction predictive value,the postoperative refraction shift toward hyperopia.

OBJECTIVE: To study the links between chronic pyelonephritis (CPN) and immune function, and the action mechanism of Yishenkang granule on CPN. METHODS: A total of 120 CPN cases were randomly assigned to Yishenkang granule group, Sanjing tablet group and western medicine group, which were compared with healthy control group. The levels of the peripheral blood T lymphocyte subsets, serum immunoglobulin, complement, secretory IgA in urine and the cell factor IL-2 in CPN cases before and after treatment were detected by monoclonal antibody method, agar diffusion method, radioimmunoassay, radioimmune balancing method and compared with those in healthy control group. RESULTS: In CPN cases compared with healthy control group, the levels of serum immunoglobulin, complement, secretory IgA in urine were significantly lower while the level of cell factor IL-2 were significnatly higher (P

Objective To compare the hemodynamics and respiratory mechanics between flexible reinforced laryngeal mask airway (FRLMA) and tracheal intubation (TI) in functional endoscopic sinus surgery. Methods Forty-six patients (ASA) scheduled for selective functional endoscopic sinus surgery under general anesthesia were allocated randomly to either flexible reinforced laryngeal mask airway group (FRLMA, n=23) or tracheal intubation group (TI, n=23) with mechanical ventilation. MAP and HR were recorded before anesthesia induction, before intubation, after intubation immediately, before extubation and after extubation immediately. Parameters for respiratory mechanics included peak inspiratory pressure (PIP), plateau airway pressure (P_(plateau)), mean airway pressure (P_(mean)), positive end expiratory pressure (PEEP), peak inspiratory flow (FI_(max)), peak expiratory flow (FE_(max)), and end tidal CO_2 (P_(Et)CO_2). All of the above indicators were recorded 5, 10 and 15 minutes after intubation. Meanwhile, arterial gas analysis was examined. Complications such as aspiration, coughing, pharyngeal pain, hoarseness, muscular soreness and unseal of FRLMA were followed up 24 hours after extubation. Results MAP and HR were significantly higher in group TI than those in group FRLMA after intubation and extubation (P<0.05). PIP, P_(plateau), P_(mean) and VD/VT were significantly higher in group TI than those in group FRLMA (P<0.05). Complications such as coughing, pharyngeal pain and muscular soreness were significantly lower in FRLMA group than that in TI group (P<0.05). Conclusions The application of FRLMA on functional endoscopic sinus surgery is a simply handling method, with minor laryngeal stimulation during intubation and extubation, more stable hemodynamics, reliable respiratory mechanics and low incidence of postoperative upper airway complications.

Objective To evaluate the efficacy of manually controlled jet ventilation with Manujet Ⅲ apparatus (VBM Co, Germany) for removal of airway foreign body in children. Methods One hundred and twenty ASA Ⅰ or Ⅱ children aged 10 months-12 yr, weighing 8-35 kg undergoing removal of airway foreign body were randomly divided into 3 groups (n=40 each) : group Ⅰ spontaneous respiration (SR) ; group Ⅱ intermittentpositive pressure ventilation through the short side tube of the rigid bronchoscope (IPPV) and group Ⅲ manually controlled jet ventilation with Manujet Ⅲ (JV). Anesthesia was induced with methylprednisolone 2 mg/kg, propofol 2 mg/kg and γ-OH 70 mg/kg in group SR (Ⅰ) and with methylprednisolone 2 mg/kg, propofol 4-5 mg/kg, fentanyl 1.5 μg/kg and succinylcholine 2 mg/kg in group IPPV and JV (Ⅱ,Ⅲ). The bronchescope insertion condition, the occurrence of hypoxia during and after operation, body movement during operation, the rate of successful removal of the foreign body, the duration of operation, anesthesia emergence time and perioperative side effects were recorded. Resulls The rate of good bronchescope insertion condition and successful removal of airway foreign body were significantly higher, the rate of hypoxia during and after operation, body movement, breath holding and restlessness were significantly lower and duration of operation and anesthesia emergence time were significantly shorter in group IPPV and JV than in group SR (P<0.05). The rate of intraoperative hypoxia was significantly lower in group JV than in group IPPV (P<0.05). Conclusion Jet ventilation with Manujet Ⅲ can reduce the occurrence of hypoxia during removal of airway foreign body in children and does not interfere with the operation.

Objective:To explore and study the clinical values of CT and MRI in the diagnosis of spinal trauma. Methods: One hundred patients with spinal trauma in our hospital were selected as the study objects and randomly divided them into 2 groups, 50 cases in each group. The control group was diagnosed by CT, the experimental group was diagnosed by MRI. Results: The efficacy of CT(control group) on fracture line and fracture flat shift was better than experimental group, but in the aspect of spinal cord injury, ligamentous injury and soft tissue injury, experimental group(MRI) was more sensitive than control group(x2=4.0, P<0.05), differences between 2 groups were statistically significant. Conclusion:Every coin has 2 sides, so as to applying CT and MRI in the diagnosis of spinal trauma, but the accuracy to overall spinal trauma of experimental group is higher. Furthermore, it can avoid misdiagnosing with spinal trauma that applying combined CT and MRI, it is worthy of being widely recommended in clinic.

Currently,the incidence of breast cancer ranks first at home and abroad of female cancer and the age of onset tends to be younger.Due to the local changes of the tumor residual cavity after the breast conserving surgery,we can't accurately delineate the irradiation range using traditional breast conserving surgery combined with external irradiation of whole breast and tumor bed plus the amount,and the course of treatment is longer.Intra-operative radiation therapy (IORT) can avoid the impact of respiratory motion and postural changes.Meanwhile,it can immediately irradiate the tumor bed intraoperative accurately.For patients,IORT can shorten the cycle of radiotherapy and reduce irradiation on the skin and subcutaneous tissue.So IORT is convenient,easy to be accepted,and it has relatively few complications,good cosmetic results and so on.In recent years,more and more Cancer Center choose breast conserving surgery combined with IORT for the treatment of early stage breast cancer and do researches to the indications,methods,dosage,efficacy and prognosis of IORT.

Objective To explore the content and gene expression of endothelial nitric-oxide synthase (eNOS) in heart of hyperlipidemia apoE-/- mice. Methods apoE-/- mice were fed with high fat diet as high-fat diet group (n= 7) and normal fat diet as control group (n = 6) for 12 weeks. Serum lipid profiles including total cholesterol (TC), triglyceride (TG), high density lipoprotein (HDL) and low density lipoprotein (LDL) were detected, eNOS mRNA expression in heart were determined by Real-Time RT-PCR, as well as protein expression by immunohistochemistry. Results Levels of serum TC, TG and LDL clearly increased in high fat diet group, while HDL decreased (P< 0. 01). mRNA and protein expression of eNOS in heart reduced in high fat diet group(P<0.01). Conclusions High fat diet may lead to hyperlipidemia in apoE-/- mice, which may down-regulate eNOS expression and decrease eNOS content in heart.
