Objective To observe the tolerance of contemporaneous multiplane operations in obstructive sleep apnea-hypopnea syndrome(OSAHS). Methods Twenty-three patients were enrolled. According to the different obstructive level, the different operations were chosen to complete upper airway reconstruction in contemporaneous operation group (group A, 13 patients). In the simple palatopharynx level obstructive group (group B, 10 patients), bilateral tonsillectomy and H-UPPP was chosen. Results The operation time in group A was significantly longer than that in group B:(121.0 ± 35.4) min vs.(80.7 ± 25.3) min, P<0.01. The hospital days and adverse events in two groups had no significantly difference (P>0.05). Conclusions Individual therapeutic schedule for OSAHS patients should be formulated. Operating the different obstructive levels simutaneously, which would solve upper airway occlusion and complete the upper airway reconstruction at the same time. No more adverse events happen, compared with the simple palatopharynx level obstructive group, though the operation time may be longer.

Objective Antimicrobial peptides are the focus of recent research in oral microbiology .This study aimed to eval-uate the activity of a novel antimicrobial peptide pm 11 against oral microorganisms and its action mechanisms . Methods We ana-lyzed the effect of pm11 on oral microorganisms and determined its antimicrobial activity in the saliva environment by measuring its min -imal inhibitory concentration (MIC), minimal bactericide concentration (MBC), and bactericidal kinetics.We observed its bacteri-cidal activity on the biofilms of streptococcus mutans by confocal laser scanning microscopy (CLSM) and the structural changes in the bacterial membrane by scanning electron microscopy (SEM). Results The antimicrobial activity of pm11 varied greatly against dif-ferent oral microorganisms , with its MIC values ranging from 2 μg/mL to 256 μg/mL and its MBC values from 2 μg/mL to >256μg/mL.The bactericidal kinetics showed a decreasing survival rate of bacteria with the lengthening of the intervention time .The inhib-itory-zone diameters exhibited no significant indifference between the water solution and the sterile saliva solution .CLSM revealed an increased number of dead bacteria in the pm 11-treated biofilms , while SEM manifested obvious changes in the shape of the bacteria membrane treated with pm11. Conclusion Our findings suggest that pm11 has a broad spectrum of antimicrobial activities on oral mi-croorganisms and a potential value of clinical application .

OBJECTIVE To set up a multiple functional information system for prevention, health care and hospital infection management in order to substitute the primitive older methods.METHODS On the platform of hospital information system, to construct above mentioned system, adopting C/S framework, the backstage supporter adopted the large-scale database of SQL SERVER 2000 enterprises edition, the front application program used Power Builder7 programming. The application software where collected all data about happened public health event, infectious disease epidemic situation and hospital information management was integrated into the each work station of the information system of hospital management, in order to form the report related to any department of the hospital, and control network. RESULTS System could come down with the public health event to which every hospital department could find the infectious disease case, hospital infection case, etc. to check, put in order, report, count, analyze, have a look around, inquire about, feedback, and form the monitoring chart with excellent pictures and texts. CONCLUSIONS This software is a medical quality control system of a hospital, can to meet suddenly public health event, infectious disease epidemic situation and hospital infection control, and raise working efficiency in real time to control hospital infection.

OBJECTIVE To achieve the best treatment effect by the effective management to control abusing the clinical antibacterial drug. METHODS The management organization and system on antibiotics reasonable application were established.It also formulated an standard to examine the reasonable antibiotics application.It construced the information system of the antibiotics reasonable application management,to carry on the real-time monitoring to the clinical antibiotics application situation. RESULTS The antibiotics utilization ratio was from original 78% lowered to 65% and the antibiotics use hastened more reasonably. CONCLUSIONS The standardized management of antibiotics use is realized and the medical quality is improved.

OBJECTIVE To explore risk factors and preventive measure of wound infection after operations in clean wounds.METHODS The related factors of wound infection were analyzed by using Logistic analysis in 6805 cases from Jun 2004 to Dec 2005.RESULTS Age,duration of operation and diabetes mellitus were the risk factors for wound infection,but the antibiotic application was unrelated to wound infection in clean wounds.CONCLUSIONS The risk factors for wound infection are age,duration of operation and diabetes mellitus.

OBJECTIVE To explore associated factors of nosocomial infection and provide ways for control nosocomial infection.METHODS The associated factors of nosocomial infection were analyzed by using retrospective analysis in 29 842 cases from Jan 2004 to Dec 2005.RESULTS Among 29 842 cases,1917 cases were infected,the incidence was 6.4%.CONCLUSIONS The associated factors of nosocomial infection are age,the underlying diseases,the decrease in immunological function and the invasive manipulation.

Objective To study the expression of fragile histidine triad(FHIT) in oral squamous cell carcinoma(OSCC),and discuss its role and significance in OSCC.Methods Immunohistochemical method was used to detect the expressions of FHIT in 48 cases of OSCC and 26 normal oral mucosa.Results The positive expression rate of FHIT in normal oral mucosa was 76.92%(20/26).Among 48 OSCC patients,the positive rate of FHIT(43.75%) was lower than that in normal oral mucosa(P0.05),but FHIT protein content was significantly associated with differentiation(P

Objective To investigate the ex pr ession of squamous cell carcinoma antigen (SCC-Ag) and carcinoembryanic antigen (CEA) and its clinical significance in patients with lung cancer. Meth ods The pre-treatment serum from 134 patients with lung cancer from 1998 to 2002 were analyzed for the SCC-Ag level and CEA level by IMX, and the correlation of the SCC-Ag level and CEA level with the clinicopathologic charac teristics were also detected. Results Significant correlations were found between the pre -treatment SCC-Ag level, and CEA level and the pathologic classification, clin ical stage, the positive rate of diagnosing lung cancer was raised by combined a ssay with serum SCC-Ag and CEA. Conclusion Pre-treatment and after-treatment measurement of serum SCC-Ag level and CEA level can be used for diagnosis, prediction of pr ognosis and monitor of after-treatment recurrence in patients with lung cancer.

Objective To analyze the relationship between clinical competence of baccalaureate nursing students and its potential related factors,and investigate the results of curriculum reform of 4-year nursing undergraduate education.Methods The records of 263 baccalaureate nursing graduates were retrieved.Variables including age,years of college education,sex,college entrance examination scores,average scores of basic courses,average scores of public courses and average scores of professional courses were collected.Clinical competence was measured by the clinical practice tests at various clinical units.The linear regression analysis was performed to find out the influencing factors of clinical competence.Results The clinical competence was significantly related to sex,average scores of public courses and average scores of professional courses(P
