OBJECTIVE: To investigate the utilization and its trend of antidepressants in Beijing.METHODS: The antidepressants used in 70 hospitals in Beijing from 2004 to 2006 were analyzed statistically in respect of the variety,consumption sum,DDDs and DDC etc.RESULTS: The consumption sum of the antidepressants used in Beijing increased year by year.CONCLUSION: Selective serotonin reuptake inhibitors(SSRIs) have become the first-line antidepressants,but the application of the tricyclic and tetracyclic antidepressants decreased year by year.The new antidepressants such as venlafaxine increased sharply.

Objective To investigate the level of serum cartilage oligomeric matrix protein (COMP) and its relationship with vascular calcification in diabetic nephropathy (DN) patients .Methods COMP was tested in 54 (DN) group and 28 matched healthy persons (healthy group) .DN group was divided into vascular calcification group (VC) and non‐vascular calcification (non VC) group .DN group was also divided into cardiovascular disease group (CVD‐y) and without cardiovascular disease group (CVD‐n) in view of the company of cardiovascular disease .Serum COMP levels was compared between the DN group and the control group ,the VS group and the non VS group ,and the CVD‐y group and the CVD‐n group .The correlations between COMP level and the occur‐rence of cardiovascular disease ,the incidence of vascular calcification were estimated by Wald analysis of the application of Wald test .Results Serum COMP in DN group was significantly higher than the control group;Aortic arch calcification accounted for 75 .9% of the DN group .The serum COMP in VC group was higher than that of non VC group ,CVD‐y group had higher COMP than CVD‐n group old respectively with every 10 ng/mL increased in concentration of serum COMP .Conclusion The higher of concentration of serum COM P ,the more risk of vascular calcification and CVD .

Objective The study aimed to know the mental health state of juvenile delinquents, to provide basis for the early prevention of juvenile delinquency and the rectification of the unhealthy mental state. Methods The 378 juvenile delinquents from Tianjin reformatory were deem to the study group, the 410 14~18 years old high school students were sampled from a common school as the control group. They were assessed and compared with SCL-90. Result The indices of SCL-90 excluding somatic change, interpersonal relationship were higher than that of the domestic routine model (P

Objective To evaluate the effect of medical hygiene wipes on disinfecting object surface and compliance to use in an intensive care unit (ICU).Methods 30 beds in the ICU at a hospital were randomly selected and divided into three groups:A,B and C,each group had 10 beds.Group A were only provided hygiene wipes,group B used towel soaked in chlorine-containing disinfectant (disinfected towel),group C were provided both medical hygiene wipes and disinfected towel for selected use.Compliance to different disinfection methods,and disinfectant efficacy on object surface were compared.Results The rate of compliance to disinfection in group A was higher than group B (78.78% vs 42.12%,χ2 =68.56,P <0.05);except medical disposal trolley and ventilator,compliance to disinfection of the other object surface in group A were all higher than group B (all P <0.05).Except ventilator, adenosis triphosphate (ATP)values before and after disinfection of object surface in group A and B were both significantly different (both P <0.05 ),disinfectant efficacy of group A was superior to group B.Group C used medical hygiene wipes more than disinfected towel ([836 times,91 .57%]vs [77 times,8.43%]).Nurses spent (20.15+ 3.00 )minutes on preparing disinfectant every day,and (15.02 ± 2.00 )minutes on washing used disinfected towel,while hygiene wipes could be used immediately,discarded after use,and was timesaving. Conclusion Use of medical hygiene wipes is convenient,rapid,and without irritating odor,it also improves disinfection effect on object surface and ICU health care workers’compliance to disinfection.

Objective To study the tumorigenetic characteristics of side population (SP) cells and their exsistence in gastric cancer cell lines and tissues.Methods Flow cytometry and the DNA-binding dye Hoechst 33342 staining were used to analyze sorted SP cells in 3 gastric cancer cell lines(SGC-7901,BCIC-823 and MKN28).SP cells and non-SP cells(main population cells)isolated from SGC-7901 cell line weresubcutaneously injected into 36 nude mice with 500,5000 or 50 000 cells per mouse,respectively.Thetumorigenity was observed 8 weeks after injection.The expression of ATP-binding cassette sub-family Gmember 2(ABcG2)mRNA in three gastric cell lines and its level in gastric cancer tissues were detected by real-time PCR and immunostaining.respectively.Results The proportion of SP cells was accounted for 1.0%in SGC-7901 cells and 1.3%in BGc-823 cells.No SP cell was found in MKN28 cells.As low as 500 SP cells or 50 000 non-SP cells could initiate tumors in mice.The expression of ABcG2 mRNA was higher in SGC-7901(O.162)and BGC-823(O.096)cell lines than that in MKN28 cell line(0.005).The value of AtCG2 mRNA/beta-aetin mRNA and protein in gastric cancer tissues was different from those in gastritis tissues.Condasimm SP cells have strong ability of tumorigenesis compared with non-SP cells.The expression of ABCG2 is found in gastric cancer tissues and part gastritis tissues.The more the SP cells in gastric cell lines,the higher the expression of ABCG2.

Background The ultrasonography for silicone tamponade eye is a problem in diagnosis and treatment of eye diseases,especially for the calculation of intraocular lens (IOL) power.IOL Master is usually used to the biometric measurement of the silicone tamponade eye in well-equipped hospital,but it is still disabled in serious cataractous eyes.Corrective B or A-type ultrasound methods have been used for a fewer years,but these measured results are incomparable probably due to the difference of viscosity of silicone oils.Objective This study attempted to investigate the accuracy of B-type ultrasonography for ocular axial length (AL) measurement in silicone tamponade eyes.Methods The transmitting speed of ultrasonic wave in the silicone oil was determined by comparing the outcomes between balance solution mesuring and 5 500 mPas silicone oil,and a calculating formula for corrective ocular AL in 5 500 mPas silicone filled eyes was further established.Thirty-two eyes of 30 patients who received 5 500 mPas silicone oil tamponade due to complex retinal detachment were enrolled in Qingdao Hiser Medical Group from May 2012 to March 2014.The eyes were assigned to the AL＜26 mm group (18 eyes of 16 patients) and AL≥26 mm group (14 eyes of 14 patients).B-scan ultrasound and IOL Master were used to measure the AL before the removal of the silicone oil,and the Als were measured again using A-scan ultrasound and B-scan ultrasound 3 months after the removal of the silicone oil.The outcomes were compared and the correlations were evaluated among different measuring methods.The vitrous length values before and after removal of the oils,and the diopters before and after intraocular pressure (IOP) implantation were compared to varify the results of B-type sonography for 5 500 mPas silicone-tamponade eyes.Results The transmitting speed of sound wave in 5 500 mPas silicone oil was 1 023 m/second with the conversion factor 0.668 between silicon oil eyes and vitreous cavity,and the corrected formula for AL measurement was:the length form cornea apex to the posterior pole of lens or the center of the capsular membrane+ 0.668×the length form posterior pole of lens or the center of the capsular membrane to the macular area.No significnant differences were found in the AL values among the corrective-B scan,IOL Master method,postoperative Bscan method and A-scan method both in the AL＜26 mm group and the AL≥26 mm group (AL＜26 mm:F=0.108,P =0.955;AL ≥ 26 mm:F =0.011,P =0.998),and the AL values by corrective B-scan was significantly correlated with that by IOL Master,postoperative B-scan and A-scan,respectively (AL＜26 mm group:r =0.876,0.921,0.809,all at P＜0.01;AL ≥ 26 mm group:r =0.943,0.956,0.955,all at P＜0.01).The vitreous cavity depth was (20.78 ±2.13)mm by corrective B-scan in 1 day before the removal of silicone,and that in 3 months after removal of silicone was (20.89±2.16) mm,without statistical diference between them (t =0.795,P =0.219).The actual postoperative refraction in 16 eyes with IOL was (-1.25 ± 1.69) D,and preoperative refrection was (-1.50 ±0.00) D,the difference was not statistically significant (t =0.585,P =0.284).Conclusions The biometry of B-scan ultrasonography for silicone-tamponade eye is accurate and simple,with a good feasibility in clinical measurement.
