Clinical observation of different combined treatment regimens on patients with high-frequency sudden sen-sorineural hearing loss / 实用医学杂志

Objective To investigate the therapeutic effect of different combination regimens on patients with high-frequency sudden sensorineural hearing loss(SSNHL). Methods 82 patients with high-frequency SSNHL from December 2013 to May 2017 were enrolled. The control group was treated with hormone,lidocaine, and genetein combination therapy,while the observation group received systemic hormones,and local hormones combined with hyperbaric oxygen therapy,the average frequency of pure tone valve improvement,complications and adverse reactions in two groups were compared.Results After the treatment,the average pure tone of the two groups was significantly improved than pretherapy(tcontrol group = 10.28,P = 0.00;tobservation group = 11.06, P=0.00),but there was no significant difference in hearing improvement between the two groups(t=0.680,P=0.698),the total effective rate in the control group was 63.41%,in which the observation group was 68.29%,the difference was not statistically significant(χ2=0.230,P=0.816),but the cure rate was 26.83% in the observa-tion group which was higher than that in the control group(7.32%)(χ2=2.05,P=0.040).There was no signifi-cant difference in improvement of complication(tinnitus and ear nausea)between the two groups(χ2Tinnitus =0.000,P=1.000;χ2Aurussion=0.000,P=1.000),and there was no obvious adverse reaction in both groups. Conclusions Treatment of high-frequency SSNHL,hormone and hyperbaric oxygen therapy is good and safe, which can effectively improve the patient′s complication(tinnitus and ear nausea).

Design and Application of Drug Traceability Management System in Outpatient of Medical Institutions / 中国药房

OBJECTIVE:To develop the drug traceability management system in outpatients of medical institutions,and gradu-ally improve its traceability management. METHODS:Based on barcode technology,drug traceability management system in outpa-tients of medical institutions was independently developed,introducing it from system environment,framework design and system function,and the application results were evaluated in terms of differences in dispensing time,deployment error,drug withdrawal treatment and applicability investigation. RESULTS:The system was developed on hospital information system network environ-ment,which was designed by combination of client/server(C/S)network system(B/S)and set function modules as follows as role rights management,data extraction,information control,data acquisition and data query. The system can match with drug electron-ic surveillance code,commodity code and other traceable barcodes,achieve drug tracing from hospitals to users through software interaction,as well as the computer-aided calibration in dispensing to effectively reduce outpatient's dispensing error. The average time for each outpatient prescription prolonged 9 s after using the system;24 dispensing errors and 4 non-normal withdrawals were prevented within 1 month;100% surveyed pharmacists expressed approval for the system's applicability. CONCLUSIONS:The system can achieve the drug suitability management in outpatients,which has shown good applicability and further improved drug safety management and control capabilities in medical institutions.

Recent progress for HBV infection model in vitro and in vivo / 中国比较医学杂志

Hepatitis B virus ( HBV) is an important pathogen threatening to human health. Up to date, various of cell infection models and animal models for HBV and the host are widely used in the exploring research of infection mechanism, new drug development and effective therapeutic method for HBV. However, these models have some defects, such as low infection rate, rather short infective stage, and comparatively large species differences with human, and so on. Among them, the biggest problem is that these models cannot completely simulate HBV infection process and pathological changes naturally occurred in human. Herein, the major HBV infection models developed in the past fifteen years, as well as the latest research progress, are presented as a brief review, to provide a reference for constructing novel HBV infection models in the future.

Doxofylline and methylprednisolone sodium succinate are stable and compatible under normal injection conditions

To assess the physical compatibility and chemical stability of doxofylline with methylprednisolone sodium succinate in 0.9% sodium chloride or 5% dextrose injection for intravenous infusion. Twenty mL doxofylline solution [0.74 mg/mL] and 1 mL methylprednisolone sodium succinate solution [0.15 mg/mL] were added into 250 mL polyolefin bags containing 5% dextrose injection or 0.9% sodium chloride injection, and stored for 24 h at 20-25[degree]C. Chemical compatibility was measured with high-performance liquid chromatography [HPLC], and physical compatibility was determined visually. The results showed that samples were clear and colorless when viewed in normal fluorescent room light. The pH value exhibited little change. The particulate content of >/= 25 micro m was low and within the specification limit. The particulate content of >/= 10 micro m decreased over time and was similar to the control solution. Analysis of chemical stability revealed that doxofylline is stable with methylprednisolone sodium succinate for up to 24 h, and the degradation of methylprednisolone sodium succinate is unrelated to doxofylline, but is closely related to the pH value of the solution. Doxofylline and methylprednisolone sodium succinate did not affect the stability of each other

Study on identification of expiratory phase X-ray image / 生物医学工程学杂志

To divide the lung from the original X-ray image, the maximum classes square error is employed in finding the threshold. Then the thorax is ascertained according to the edge-detection and tracking-bug method, and the lung is divided from the thorax by the thresholding segmentation method. The gray mean in the lung is regarded as the eigenvalue to identify the image, but it doesn not work well. In view of the dosage of the X-ray exposure and the difference between persons, a new method that adopts the ratio of the gray in lungs to the gray in bones as the eigenvalue is brought forward to identify the image. And the two methods are compared by using the distance between classes. The result shows that the second method is more effective.

System Review on Curative Effect and Safety of Dexamethasone for Severe Asthma and Severe Sepsis / 中国药房

OBJECTIVE:To evaluate the curative effect and safety of dexamethasone for severe asthma and severe sepsis systematically.

Therapy results of severe asthma:(1)in remission rate of the total symptom,difference between dexamethasone and prednisone was not statistically significant [OR 1.44,95%CI(0.75, 2.75);P=0.27];(2)In the incidence rate of ADR,dexamethasone was lower than prednisone [OR 0.13,95%CI(0.04,0.44);P= 0.001];(3)In the recurrence rate,no statistical significance was noted in difference between dexamethasone and prednisone [OR 0.58,95%CI(0.25,1.31);P=0.19]. Therapy results of severe sepsis:(1)In the mortality,difference between dexamethasone and placebo was not statistically significant [OR 0.85,95%CI(0.41,1.78);P=0.67];(2)In the incidence rate of ADR,no statistical significance was noted in difference between hydrocortisone and placebo [OR 1.05,95%CI(0.51,2.19);P=0.89]. CONCLUSION: Dexamethasone is similar to prednisone in the treatment of severe asthma but better than prednisone in drug safety. The safety of dexamethasone is similar to placebo in the treatment of severe sepsis.
