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.

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 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.

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.

SUMMARY Lymphoma is a systemic disease. It is not uncommon to be found involved in digestive or central nervous system. However, lymphoma involved in these two systems at the same time is rare. The clinical feature of a case of lymphoma with gastrointestinal bleeding and limbs weakness was investigated and the literature was reviewed. The patient came to our hospital with melena and hematemesis. She was diagnosed as gastric ulcer by gastroscopy and biopsy showed lymphoma. Two days after she came to hospital, the patient presented with progressing limbs weakness. Magnetic resonance imaging (MRI) showed irregular abnormal signals in T2-T4 vertebra, which was enhanced obviously. A strip abnormal signal could be seen in spinal cord and involved in neighboring centrum and ribbing. The lesion extended to paravertebral tissue. The final diagnosis was lymphoma involved in stomach and spinal cord. Diseases presented with both upper digestive tract bleeding and symptoms of central nervous system were rare, including malignancies, virus infection and some therapy. Lymphoma was one of the causes. On the other hand, spinal cord ischemia might occur after gastrointestinal bleeding. Thus, doctors should examine the patients carefully to diagnose these diseases.
