Objective To investigate the clinical diagnosis and treatment of cosmetics-induced skin lesions.Methods The medical history,clinical manifestation and treatment effects were reviewed in 6230 cases of cosmetic skin damage during 2001-2012.Results The characteristics of cosmetic skin damage included the thinning of the cuticle,glossiness increases and pigment macule during the use of cosmetics time,increased pigment macule after stop and increased blood capillary.A comprehensive treatment was given,including the removal of the causes,correct use of cosmetics,promoting skin metabolism,laser and IPL treatment and maintenance.Through the treatment for 1-2 years,facial cosmetic skin damage returned to normal,and the effects of both doctors and patients were satisfactory.Conclusions Combining with the clinical history,a diagnosis of cosmetics skin damage can be made based on the above 4 characteristics.Comprehensive treatment method is worthy of clinical application.

Objective:To establish an HPLC method for the determination of the concentration of ganciclovir in vitro,and to inspect sustain-release of medical biofibrin glue carrying Ganciclovir. Methods:The HPLC system consisted of water-methanol(98:2)as mobile phase with the flowrate of 1.0 ml/min,and the detection wavelength was 252 nm and the injection volumn was 20 ?l. Column tempetature was 30℃. Results:The linear range of ganciclovir was 5~350 ?g/ml(r=0.9996),displaying a good linear relationship. The within-day and between-days relative standard deviations(RSD)were 0.89%～2.35%. The methodological recovery ranged from 98.4 % to 100.8 %. The elaborated method was sensitive,precise and applicable for determining the concentration and release rate of ganciclovir in vitro. Conclusion:The sustain-release effect of medical biofibrin glue carrying ganciclovir in vitro is good.

To emphasize the great function of medical engineering science in the development of sanitarium through analyzing the actual status of medical engineering science in military sanitarium,especially the actual status of management for medical equipment. Starting from the overall management of medical equipment,the reinforcement of medical engineering construction in sanitarium shall ceaselessly develop the connotation of medical engineering and improve the professionalism of medical engineering staff through various ways,so that it can contribute to the healthy,stable and fast development of military sanitarium.

By analyzing the present medical metrology in army medical service units,the importance of medical metrology is emphasized in the development and construction of every unit.In particular,manifold methods should be used to unceasingly improve the professional quality of medical metrology personnel.The development and construction of this subject should be unceasingly expanded in its connotation.It is expected to promote the development of medical service units in a healthy,stable and rapid way by strengthening the construction of medical metrology.

Objective: To evaluate the development, safety and efficacy of percutaneous nephrolithotomy(PNL) for management of upper urinary tract calculi in pediatric patients.Methods: In the study, 77 pediatric patients undergoing 87 PNLs through mini or standard tract for upper urinary tract calculi between January 2005 and December 2016 in Peking University People''s hospital were reviewed, including 69 renal calculi, 6 upper ureteral calculi, 12 renal and upper ureteral calculi, 35 single calculi, 43 multiple calculi and 9 staghorn calculi.The development and efficacy of PNL in pediatric patients were studied by analyzing the characteristics and clinical indexes, and by reviewing the associated literature.The Clavien classification system was used to evaluate the complications after PNL.Results: A total of 87 PNLs were performed in 77 pediatric patients.Eighty-one upper urinary tract calculi were managed through a single tract(93.1%), 5 pediatric patients were managed through 2 tracts(5.7%), and 1 pe-diatric patient was managed through 3 tracts(1.2%).The mean operating time was (77.0±29.8) min.The stone-free rate after one session was 100% for single calculi and 71.2% for multiple or staghorn calculi, 5(5.8%) children underwent auxiliary procedure to remove the residual calculi and the final stone-free rate of PNL was 88.5%.One of the main complications of pediatric PNL was fever.Sixteen(18.4%) had moderate fever(38-39 ℃), 5(5.7%) had high fever(39-40 ℃) and there were no severe complications of infection, such as sepsis or septic shock.The mean hemoglobin loss was (10.3±16.1) g/L and the serum creatinine rise was (7.0±13.3) μmol/L.One(1.2%) pediatric patient suffered ureteroscopic lithotripsy because of the obstruction by the residual stone in ureter.No injury of organs or retroperitoneal urinary extravasation occurred.General assessment of the complications showed Clavien grade Ⅰ complications in 14 (16.1%) pediatric patients, grade Ⅱ in 7(8.0%) children and grade Ⅲ in 1(1.2%) children.There was no grade Ⅳ or Ⅴ complications.The overall complication rate was 25.3%.Conclusion: PNL for management of upper urinary tract calculi in pediatric patients is effective.Complications after PNL, as assessed with Clavien classification system, are mild and PNL in pediatric patients is safe.

The emphasis and basic target of medical education is to cultivate medical students with high qualities. The qualities of medical students include professional ethics, self-cultivation, medical knowledge and physical-psychological quality, which is critical to the medical education. It has been proven that the teaching of Clinical Pathway is one of the most important factors to promote the improvement of comprehensive qualities of medical students.

Ophthalmology is a clinical course which requires students to have practical skills. The traditional clinical teaching method lacks varied means resulting in unsatisfactory teaching effects. Application of multimedia technology not only changes the teaching model, enriches the teaching contents but also improves the quality of ophthalmology teaching. By analyzing the advantages and disadvantages of multimedia application in clinical teaching based on our practice, the paper raises some methods for improvment in order to achieve the best teaching effects.

Objective To evaluate the efficacy of Mahuang-Fuzi-Xixin decoction and Wuling powder combined with routine western medicine therapy for chronic kidney disease (CKD) stage 3.Methods A total of 65 patients with CKD stage 3 were recruited and randomized into a treatment group (32 cases) and a control group (33 cases).On the basis of the same routine western medicine therapy,the patients in the treatment group was treated with Mahuang-Fuzi-Xixin decoction and Wuling powder,while those in the control group was treated with ketosteril.All patients were treated for one month.Renal function was evaluated by serum creatinine,urea nitrogen and uric acid before and after treatment.The therapeutic effect was compared between the two group.Results The serum ereatinine after treatment in the treatment group was significantly decreased than that in the control group (387.52 ± 92.13 mol/L vs.502.78 ± 117.35 mol/L;t=4.395,P＜0.01).The total effective rate in the treatment group was significantly higher than that in the control group (87.5％ vs.42.4％;X2=12.533,P＜0.01).In respects of syndrome improvements,tiredness/weakness (90.6％ vs.48.5％,x2=11.637),waist soreness/leg weakness (90.0％ vs.35.5％;x2=17.040,P＜0.01),anorexia and tympanites (93.3％ vs.37.9％;x2=17.802,P＜0.01),loose stool (93.1％ vs.25.8％;x2=25.219,P＜0.01),anasarca (84.6％ vs.41.7％;x2=8.214,P＜0.01),pale and teeth-printed tongue (76.7％ vs.26.7％;x2=13.081,P＜0.01) in the treatment group were significantly better than those in the control group.Conclusions Mahuang-Fuzi-Xixin decoction and Wuling powder combined with routine western medicine therapy can improve the renal function and syndromes in patients with CKD stage 3.
