OBJECTIVE To investigate the clinical curative effect of acellular dermal matrix contrast with temporalis fascia in type Ⅰ tympanoplasty. METHODS A retrospective analysis of 60 inflammatory chronic suppurative otitis media patients from January 2014 to January 2015 in Genenral Hospital of PLA Guangzhou Military Area were conducted.All cases were perpormed the ear incision under local anesthesia, including 32 cases(32 ears) with acellular dermal matrix, 28 cases(28 ears) with temporal fascia. The operation time, postoperative pain, the healing of tympanic membrane and the postoperative recovery were compared between the two groups. RESULTS There was significant difference in the operation time and postoperative pain between the two groups(P<0.05). There was no significant difference in the success rate of tympanic membrane healing and postoperative hearing improvement(P>0.05). CONCLUSION The effect of acellular dermal matrix for repairing tympanic membrane is similar to the temporalis fascia. The use of acellular dermal matrix has the advantage of shorter operation time, less postoperative pain, and can avoid regional two incisions, it is worthy of clinical application.

Objective Obstructive sleep apnea hypopnea syndrome (OSAHS) often causes damage to multiple systems, especially to the central nervous system, inducing cognitive dysfunction.This study aims to explore the possible correlation of the expressions of serum hypoxia-inducible factor-1α (HIF-1α) and brain-derived neurotrophic factor (BDNF) with cognitive impairment in rats under different hypoxia conditions.Methods Twenty-four Wistar rats were equally randomized into a normal control, a chronic intermittent hypoxia (CIH), and a chronic continuous hypoxia (CCH) group.The rats of the CIH group were placed in a hypoxia chamber filled with N2 and air, the oxygen concentration switched from (7±0.5)% to 21%, 1.5 minutes for each state and 4 minutes for each cycle, while those of the CCH group were placed in another hypoxia chamber with the oxygen concentration of (7±0.5)%, 8 hours a day and all for 30 days.Then we recorded the body weight of the rats, detected the expressions of serum HIF-1α and BDNF by ELISA, and observed the changes of behavior by Morris water maze test and those of the hippocampal morphological structure by HE staining.Results At 30 days after modeling, the body weight of the rats was significantly decreased in the CIH and CSH groups as compared with the normal control ([195.75±6.497] and [180.88±12.017] vs [218.63±15.287] g, P<0.05).Positioning navigation showed that the escape latency was significantly longer in the hypoxia models than in the controls (P<0.05), even longer in the CIH than in the CCH group (P<0.05).Spatial exploration test manifested a lower frequency of crossing the platform in the CIH and CCH groups than in the control ([2.63±1.45] and [3.22±1.30] vs [4.97±0.47] times, P<0.05).The expression levels of serum HIF-1α and BDNF were significantly higher in the CIH ([36.14±9.34] and [1625.34±332.44] pg/mL) and CCH ([27.27±6.88] and [1204.07±363.81] pg/mL) than in the normal control group ([14.11±4.06] and [1036.40±124.48] pg/mL) (P<0.05), even higher in the CIH than in the CCH group (P<0.05).HE staining exhibited scattered and disorderly arrangement of hippocampal neurons in the model rats, with unclear nuclear membrane, pyknosis of the nuclei, darkly stained cytoplasm, and some damaged cells.More obvious absence and vacuolization of some cells were observed in the rats of the CIH group.Conclusion Chronic hypoxia inhibits the growth and development of rats and induces cognitive dysfunction.High-level HIF-1α in chronic intermittent hypoxia indicates hypoxia-stress of the body, while compensatory increase of serum BDNF may be involved in neuronal cell damage regulation.

Objective To measure the financial burden incurred by hypertension to urban patients in Beijing, Nanjing and Hangzhou cities. Methods Two communities were sampled from the three cities randomly, and 300 hypertension patients were sampled randomly from hypertension control files in each community for questionnaire survey. Results Health expenditure of the families with hypertension patients accounts for 14. 4% of the family's income, and 18. 2% of the family's expenditure, a ratio far beyond the national average (10.6 %). However, the majority of them report the burden as affordable.The basic medical insurance for urban residents helps alleviate the financial burden of hypertension patients and the extent of such burden has a close bearing on the outcome of hypertension treatment and prevention. Conclusion Effective community-based blood-pressure monitoring and control system is key to reducing the financial burden of hypertension. The reimbursement policy for hypertensive patients within the basic medical insurance is expected to be further improved.

Objective The application of laboratory information system (LIS) increases extensively. The objective is to expatiate how to widen the application of LIS so that it can be seamlessly combined with HIS, and play a greater role in quality control of clinical laboratory. Methods A consummate and compact working process was designed. A bidirectional communication from equipment to client was established. Module modes and prefect security systems were set up. Results With the existing HIS network environment, corresponding bar codes were generated through the examination applications from the doctor's workstation. At the same time, patients' basic information and test information were generated based on the bar code. In this way, the seamless combination of LIS and HIS were achieved. The switch of the functional module was simple, efficient and easy to maintain. The internet version Kaspersky antivirus software was used in the area of security. Database were backed up automatically and regularly. Authority was strictly defined for operators in different level. Conclusion Through the current application in our section, LIS has already been an essential part in the process to become a modern hospital.

ObjectiveTo assess the characteristics of left ventrlcular ( LV) systolic syncnrony before and 6 days after percutaneous transluminal septal myocardial ablation(PTSMA)in patients with hypertrophic obstructive cardiomyopathy (HOCM) using two dimensional speckle tracking imaging(2DSTI),and to investigate correlation between the LV systolic synchrony and LV outflow-trace gradient (LVOTG).MethodsLVOTG were measured before and 6 days after PTSMA in 21 patients with HOCM.The two dimensional loop-cinec were obtained in three levels of the short axis views of LV (mitral valve,papillary muscle and cardiac apex).The time from the onset of QRS complexes to systolic peak strain from the radial vectors (TRs) was recorded using 2D-STI.The standard deviation of the TRS of 18 segments (TRsSD) were calculated as indicator of LV systolic synchrony.Results Six days after PTSMA,LVOTG decreased significantly from (84.3 ± 19.1)mm Hg to (40.6 ± 8.3)mm Hg( P ＜0.01).TRS of the base and middle segments of anteroseptal were prolonged dramatically( P ＜0.05) 6 days after PTSMA compared with that before.There were no significantly differences in TRs-SD of LV between before and 6 days after PTSMA ( t =1.03,P ＞ 0.05).Decreased LVOTG correlated moderately to prolonged TRS of the base segments of anteroseptal ( r =0.657,P ＜0.05).Conclusions2D-STI can detect exactly the characteristics of LV systolic synchrony before and 6 days after PTSMA in patients with HOCM.

Objective To analyze the antimicrobial susceptibility of Mycoplasma isolates for rational antimicrobial therapy. Methods BioM?rieux IST kit was used for identification and susceptibility testing of Mycoplasma strains.Results Mycoplasma was positive in 49.5% of the specimens tested.Of the Mycoplasma detected,Ureaplasma urealyticum(Uu)alone accounted for 74.7%,Mycoplasma huminis(Mh)alone accounted for 18.1%,and Uu+Mh was identified in 7.2% of the patients.The results of antimicrobial susceptibility testing showed that the Mycoplasma isolates were most susceptible to doxycycline (98.1%).Ciprofloxacin was the least active (17.3%).Conclusions Doxyeycline,josamycin,and clarithromycin can be used in the treatment of urinary tract infections caused by Mycoplasma.

Pololike kinase 1(Plk1)contain an Nterminal Ser/Thr kinase catalytic domain and a Cterminal region that contains two poloboxes.As a key regulator of multiple steps during cell cycle across eukaryotic species,many proteins interact with Plk1.Plk1 is highly expressed in malignant cells and serves as a negative prognostic marker in specific human cancer types.Plk1 is a potential target for cancer therapy.Some novel smallmolecule inhibitors of pololike kinase 1 provide novel opportunities for cancerdrug discovery,such as BI 2536,ON01910.
