Objective To explore the feature and the optimal treatment of kidney stones in children associ-ated with infant formula which had been aduherated with melamine.Method Total of 47 cases of urinary stone and 31 cases of acute renal failure caused by urinary multiple obstruction in children associated with infant formula which had been adulterated with mlelamine in Beijing Children's Hospital University of Medical Science,form Jan-uary to November,2008 were retrospectively analyzed.Results Infant formula which had been adultemted with melamine may lead to kindey stones in 15 days.The mean age was 11-month and the ratio of male to female was 2.6:1.The kindey stones were usually multiple and mostly located either in the ureteropelvic junction or all through the ureter.In the view of the renal function resuming duration,there was no statistic difference among the acute renal failure group,operation group and the conservative group(P=0.683～0.846).In children with uri-nary obstruction and acute renal failure,hemedialysis or peritoneal dialysis was performed.83.9%were relieved by posting catheter through panedoseope and blood purification.100% of the patients resumed normal renal func-tion.81.3% of the patients without acute renal failure had recovered after conservative therapies such as infusion.Conclusions The patients associated with infant formula which had been adulterated with melamine were Usually little infants.Male were more vulnerable than female.Most of them had recovered smoothly and the renal function resumed normal after effcient therapies.

Cartilage antuumor component (CATC) was isolated from a 1 mol/L guanidine hydrochloride extract of bovine cartilage by acetone fractioned precipitation and superfiltration. Using human skin fibroblasts as a normal control, it was demonstrated that CATC inhibited the DNA synthesis of Hela, QGY7703 tumor cell lines and bovine artery endothelial cells, but accelerated the normal cells, when the concentration was below 1250 ?g/ml. At the concentration of 5 000 ?g/ml, CATC inhibited the two cell lines. With human tumor stem cell assay, CATC inhibited the stem cell growth of Hela and QGY7703 cell lines. These suggest that CATC has the effects of inhibiting angiogenesis and tumor cells.

At present, microbe surface display system mainly involves phage surface display system, bacte- rial surface display system, yeast surface display system and virus surface display system. Baculovirus sur- face display system is a new type of eukaryote surface display system which developed based on deeply un- derstanding of construction and function of virus genome in recent years. Through fused expression with vi- ral capsid or membrane proteins exogenous peptides can be displayed on the surface of the virus and formed hedgehog-shape "fake virus". Baculovirus surface display system was characterized by safeness and high performance, furthermore, this system can complete post-translation processing and modification of protein to enhance the bioactivity of exogenous product. Combined with the author’s experimental work, this paper briefly introduces the mechanism and traits of this system and summarizes the newest research development on its application in the field of monoclonal antibody preparation, new-type vaccine development, genes transduction and genes therapy. It is believed that the system above may show extensive application through further improvement and optimization.

Objective To evaluate the effect of continuous adenosine infusion on mesentery microcirculation during cardiopulmonary resuscitation in rats with asphyxia. Methods Rat model of asphyxia was established in 22 healthy Wistar rats. The animals were then randomly divided into normal saline group (group A, n=10), epinephrine group (group B, n=6) and epinephrine plus adenosine group (group C, n=6). After a 3-min asphyxia without intervention, cardiopulmonary resuscitation (CPR) was started. The cardiac compression was carried out with an electric cardio-pulmonary resuscitation machine (200 times/min). Respiration was restored and maintained with a ventilator with tidal volume of 4ml, breathing rate 50times/min and FiO2 100%. After a 4-min CPR, rats in group A and group B were given normal saline and epinephrine (bolus of 90?g/kg) respectively, and in group C epinephrine (bolus of 90?g/kg) plus 70?g/kg adenosine were given. Electric defibrillation would be initiated if there was ventricular fibrillation. The reperfusion rate of mesentery arterioles and venules, diameter of blood vessels and relative blood velocity were observed. Results The reperfusion rate of mesentery arterioles and venules was significantly higher in group C than in group B (P

The main purposes of translational Medicine is to break the barrier among the basic medicine,clinical medicine and drug R&D in order to establish direct and close connection and cooperation between them.However,so far almost in the world wide,translational medicine is still at the exploration stage and far away from the real transformation.This article reviewed the difficult position of translational medicine cooperation from the three aspects of cooperative resources,sponsor and domestic culture,and then suggested to promote clinical medicine research,set up new assessment systems which focus on classified evaluation and representative work,as well as create the culture of cooperation.

Objective: To prepare ibuprofen sustained-release dropping pills, to evaluate the accumulative release percentage in vitro and to study the drug state in the base.Methods: With the drug content, mass ratio of water-soluble base to insoluble base and mass ratio of stearic acid to glyceryl monostearate as the investigation factors, and the comprehensive score of 2-hour and 10-hour cumulative dissolution rate as the evaluation index, a Box-Behnken response-surface method was used to screen the optimal formula of ibuprofen sustained-release dropping pills.The drug state in the matrix was examined by differential scanning calorimetry (DSC).Results: The optimal formula of ibuprofen sustained-release dropping pills was as follows: the drug content of 10%, water-soluble and insoluble matrix ratio of 4∶1, and stearic acid and glyceryl monostearate ratio of 3∶1.The maximum cumulative dissolution rate of ibuprofen sustained-release dropping pills was 78.85%.The DSC analysis showed that the drug crystallization peak disappeared in the sustained-release dropping pills, and formed a solid dispersion.Conclusion: The preparation has good sustained-release effect, and the preparation process is simple.

Objective:To explore the main factors of hypothyroidism after radiotherapy and to identify the optimal thyroid dosimetric parameters by analyzing the dosimetric parameters of the thyroid.Methods:The general clinical characteristics and dosimetric parameters of 206 patients with nasopharyngeal carcinoma treated in Cancer Hospital of University of Chinese Academy of Sciences were collected, and the correlation between them and the incidence of hypothyroidism was analyzed.Results:The incidence of hypothyroidism in patients with nasopharyngeal carcinoma after radiotherapy was 50.49%(104/206). Univariate analysis showed that gender, N-stage, volume, mean dose, V 20Gy, V 25Gy, V 30Gy, V 35Gy, V 40Gy, V 45Gy of thyroid were associated with the incidence of hypothyroidism. Multivariate analysis demonstrated that volume (≤12.82 cm 3) and mean dose of thyroid were the independent risk factors of hypothyroidism. Mean dose of thyroid combined with volume could significantly predict the incidence of hypothyroidism after radiotherapy. Conclusion:Mean dose of thyroid ≤ 47.21 Gy is the optimal dosimetric parameter for radiation-induced hypothyroidism, especially the patients with thyroid volume ≤ 12.82 cm 3 should pay more attention to the protection of thyroid gland during radiotherapy.
