[ABSTRACT]OBJECTIVETo evaluate the efficacy of combined oral and intratympanic glucocorticoids treatment for severe to profound sudden sensorineural hearing loss(SSNHL).METHODSFifty-four patients with severe to profound SSNHL were retrospectively studied. They were treated with oral steroids, vasodilators, anticoagulants. The patients who accepted intratympanic methylprednisolone sodium succinate were included the therapy group, the others were included in the control group. Hearing improvements were analyzed respectively after two weeks.RESULTSHearing in both groups were improved significantly after treatment(P<0.01), but there was no difference in hearing improvements between two groups(P=0.194). The efficacy for severe SSNHL patients in therapy group was equal to those who were in control group (P=0.251), so was the efficacy for profound SSNHL patients in both groups(P=0.380).CONCLUSIONThe combined systemic and intratympanic glucocorticoids treatment was effective for patients with severe to profound SSNHL, but while with no better efficacy than oral glucocorticoid alone.

Objective Random allocation concealment is important in ensuring high-guality randomized controlled clinical trial.In this paper , we aimed to design a more convenient and effective two couplet random allocation method through improving the random allocation concealment technology which uses the envelope method . Methods According to the randomized sequence , a two-couplet random allocation should be prepared for every subject and bound into a book in order , which named random assignment book with cover and instructions .The first couplet is to collect the enroll information and the second couplet is to show the allocation informa -tion.The serial numbers of the two couplets which around sealant are the same , and leave blank at the same areas of the two couplets for signing the enter information .The content of the first couplet can be completely copied to the second couplet .In order to avoid expo-sing the allocation information in advance , the back of the second couplet should be black-printed. When the subjects are sure qualified, the researchers selected the corresponding two couplet in a sequential order .Exposing the allocation infromation in the second couplet, and the subjects will be allocated to the group designated on the second couplet .This random allocation book should be entrusted to professional printing mechanism ,printing according to the random assignment sequence table and in the strict quality control .For the multicenter clinical trials , it can be printed in parts . Results The method has been implemented in nearly ten randomized controlled trials and obtained the consistent high praise . Conclusion The random allocation book method is easy to produce , simple operation and convenient in monitoring , which can effectively achieve the random allocation concealment in a clinical trial as well as having a sig -nificantly practical value in ensuring the quality of randomization .

OBJECTIVE:To observe the efficacy and safety of domestic cefepime in the treatment of patients with acute exacerbation of chronic obstructive pulmonary diseases (AECOPD) complicated with respiratory failure. METHODS:A total of ninety-six patients with AECOPD complicated with respiratory failure were randomly assigned to receive cefepime 2.0 g bid iv gtt (Group A,n=48) or cefoperazone/sulbactam (Group B,n=48) at a dose of 2.0 g bid iv gtt for 7～14 day. RESULTS:The effective rate was 82% for Group A versus 62% for Group B(P0.05). CONCLUSION:The efficacy of cefepime is higher than that of cefoperazone/sulbactam in the treatment of patients with AECOPD complicated with respiratory failure,but both had good safety.

OBJECTIVE:To evaluate the cough-relieving and sputum-eliminating efficacy and safety of Guaifenesin Pseudoephedrine Hydrochloride-Codeine Phosphate Oral Solution.METHODS:By a randomized control study,a total of 60 patients characterized by nonproductive cough andlittle sputum were randomly assigned to receive Guaifenesin Pseudoephedrine Hydrochloride-Codeine Phosphate Oral Solution(Trial Group)or Ambroxol Hydrochloride Oral Solution(Control Group)l0 mL tid for 5～7 d.RESULTS:Both groups had a significant improvement in symptoms including cough and expectoration after treatment(P0.05).CONCLUSION:Guaifenesin Pseudoephedrine Hydrochloride-Codeine Phosphate Oral Solution is more effective in relieving cough than Ambroxol Oral Solution,and it has certain effect in eliminating phlegm.In addition,it is safe and has little adverse reaction.

Objective: To evaluate the frequency of MSI in epithelial ovarian tumors and its relationship with clinicopathologic features. Methods: Ninety fresh specimens of epithelial ovarian tumors, including 74 primary and 16 secondary tumors, were collected. Microsatellite analysis was carried out using 5 mono- and dinucleotide markers from the National Cancer Institute Consensus Panel by fluorescence-labeled polymerase chain reaction. Results: Of 90 epithelial ovarian tumors analyzed, 18 demonstrated a high level of microsatellite instability (MSI-H), 30 demonstrated a low level of microsatellite instability (MSI-L), and the remaining 42 exhibited microsatellite stability (MSS). Frequency of microsatellite instability (MSI) at loci BAT-25 was higher than that at any other loci. No correlation was found between MSI level and patient age, tumor type, tumor differentiation (P>0.05). But the microsatellite instability-high phenotype correlates with clinical stage.It tended to occur more frequently in early-stage tumors (P=0.03). Conclusion: The frequent MSI in epithelial ovarian tumors suggests that it is an early event to involve in the development of epithelial ovarian tumors.

OBJECTIVE:To provide the basis for the formulation of the health intervention strategy for medical and health insti-tutions'pharmacists and provide reference for other related research. METHODS:A total of 180 medical and health institutions' pharmacists in Heilongjiang province were investigated and evaluated by work satisfaction MMSS scale(modified)and quality of life(SF-36)scale,and the relevant data were analyzed statistically. RESULTS:A total of 180 questionnaires were distributed and 134 valid questionnaires were collected. The effective recovery rate was 74.44%. The average score of work satisfaction degree was (3.44±0.79),which was at the middle level. The highest score was the relationship with colleagues and the lowest score was wel-fare. The physical function,the physiological function and the social function dimension of the respondents were higher thanChi-nese norm. The scores of physical pain,general health,vitality,emotional function and mental health were lower thanChinese norm,and there was statistical significance between the scores of the other dimensions andChinese norm(P<0.05),except for the physiological function and vitality dimension. Multivariate analysis showed that gender,duties,education,length of service and work satisfaction score had an effect on quality of life(P<0.05),among these factors,work satisfaction score was positively correlated with quality of life. CONCLUSIONS:The quality of life of medical and health institutions'pharmacists still needs to be improved,which is related to many influential factors,and job satisfaction is an important influential factor.

Objective To investigate the application value of virtual touch tissue quantification (VTQ) technique in staging of chronic kidney disease (CKD). Methods VTQ examination was performed on a random sample of 96 CKD patients at different clinical stages and 45 healthy volunteers (control group). Shear wave velocity (SWV) of renal parenchyma was measured and compared. Correlation between SWV and clinical stage and glomeru-lar filtration rate (GFR) of CKD patients was analyzed. Results The SWV value of renal parenchyma decreased gradually, along with the progression of CKD disease and impairment of renal function. There was no significant difference(P>0.05)between the control group and the CKD1 group ( P=0.061), the CKD2 group and the CKD3 group (P = 0.238), and the CKD4 group and the CKD5 group (P = 0.624). The difference of SWV between the remaining groups was statistically significant(P < 0.05). SWV of renal parenchyma was negatively correlated with CKD stage (r =-0.65, P < 0.001), which means the higher the stage of CKD was associated with the lower the SWV. SWV was positively correlated with GFR (r = 0.73, P < 0.001), which means the lower the GFR was related to the lower the SWV. Conclusion VTQ technique can noninvasively reflect the changes of renal parenchyma elas-ticity and evaluate the impairment of renal function in CKD patients. It can provide a new quantitative evaluation index for the clinical staging of CKD.

AIM: To investigate the effect of PMA(phorbol 12-myristate 13-acetate) on the expression of CD18 and the mechanism. METHODS: The technique of quantitative RT-PCR analysis was used to measure the expression of CD18 mRNA in U937 cells treated by PMA. RESULTS: PMA could significantly induce CD18 mRNA expression in a dose and time-dependent manner. The induction effects of PMA on CD18 mRNA could be inhibited obviously by Myr (2 ?mol/L), a specific inhibitor of PKC, and APDC, an inhibitor of NF-?B, but not be inhibited by curcumin, a inhibitor of transcriptional factor AP-1. CONCLUSION: PMA enhanced the expression of CD18 via the pathway of PKC. Transcriptional factor NF-?B, but not AP-1, was essential for the gene transcription of CD18 in U937 cells treated by PMA.
