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.

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.

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.

OBJECTIVE: To determine the contents of telmisartan and hydrochlorothiazid in compound telmisartan preparation by TLC. METHODS: Using acetic ether-chloroform-methanol-glacial acetic acid (50∶40∶10∶5) as developer, the contents of telmisartan and hydrochlorothiazid were determined by dual wavelength thin layer chromatography with the reflection linearity parameter SX=7 and slit=1.0 mm?5.0 mm. The determinated wavelength of telmisartan was as follows: ?R=365 nm and ?S=305 nm; the wavelength of hydrochlorothiazid was as follows: ?R=370 nm and ?S=275 nm. RESULTS: The linear ranges of telmisartan and hydrochlorothiazid were 1.114～5.57 ?g (r=0.999 6) and 3.664～18.32 ?g (r=0.999 8), respectively, and the average recovery rates of telmisartan and hydrochlorothiazid were 97.95% (RSD=1.30%) and 98.32% (RSD=1.13%), respectively. CONCLUSION: The method is simple, rapid, accurate and it can be used for the quality control of compound telmisartan preparation.

There is no unity in judgment of obesity at home and abroad.WHO considered that there should have different evaluation criteria from childhood below and above 10 years and recommended "weight for height" be used for children under the age of 10 and body mass index(BMI)for children aged 10 to 24 years old.International Obesity Task Organization(IOTF) recommended BMI be suitable for young children for judgment overweight and obesity.Both of them had the same BMI standards for overweight and obesity for 18-year-old,25 and 30 kg/m2,respectively.But the Working Group on Obesity of China(WGOC)developed a criterion which cut-offs in 18 years were lower than that of WHO and IOTF,24 and 28 kg/m2,respectively.The treatment of obesity in childhood was different from that in adults.Many methods used for adults such as surgical liposuction,slimming drugs,hunger therapies and fasting could not be appropriate for childhood.A combined treatment in childhood including behavior modification,diet adjustment and exercise was recognized domestically and internationally.
