With the increased survival of the low birth weight,brain injury in the premature infants be-comes a problem of enormous importance. The introduction of the term “encephalopathy of prematurity” is the current recognition that preterm brain injury is a complex of white and gray matter damage. The combination of white matter injury and neuronal/axonal deficits constitutes encephalopathy of prematurity. The preterm infants develop primary destructive brain lesions,secondary degeneration and disturbance of maturation from hypoxia-is-chemia and inflammation,which leads to cerebral palsy,cognitive,behavioral,or language deficits. This article reviews the neuropathology,pathogenesis,therapy and neurodevelopmental disability of encephalopathy of pre-maturity.

Objective To establish the method to determine the content of berberine in Double Yellow Antiinflammatory Tablets. Methods Using HPLC, with Diamonnsil C18 (4.6 mm?250 mm, 5 ?m) as column, acetonitrile-0.05 mol/L potassium dihydrogen phosphate (35∶65, phosphate regulation pH value to 3.0) as mobile phase, detection wavelength was at 345 nm, flow rate was 0.8 mL/min, and column temperature was 30 ℃. Results In berberine range of 0.040 7～0.447 9 ?g, the scope and content of the sample peak area had a good linear relationship, reproducibility of RSD=0.59% (n=5), and the average recovery rate was 96.71% and RSD=0.37% (n=5). Conclusion This method is stable, reliable, with high sensitivity and good reproducibility, and easy to put into practice, so it can be used for quality control of Double Yellow Antiinflammatory Tablets.

OBJECTIVE: To summarize and analyze the physiological parameters of the gastrointestinal tract, as well as the progress in research of biorelevant dissolution media. METHODS: Related literatures in recent years were reviewed. RESULTS: The biorelevant dissolution media based on physiological relevant information were used to establish the methods of dissolution evaluation in vitro. CONCLUSION: With depth understanding of the physiological parameters of the gastrointestinal tract, in vitro dissolution of dosage form in biorelevant dissolution media could predict in vivo dissolution performance. In addition, biorelevant media were utilized to investigate the food effect on dissolution. Therefore, the liability of evaluating in vitro-in vivo correlation is further improved.

Objective To explore an algorithm to define the threshold value for tumor contouring on 18F-fluorodexyglucose (FDG) PET imaging. Methods A National Electrical Manufacturing Association (NEMA)NU 2 1994 PET phantom with 5 spheres of different diameters were filled with 18F-FDG. Seven different sphere-to-background ratios were obtained and the phantom was scanned by Discovery LS 4. For each sphere-to-background ratio, the maximum standardized uptake value ( SUVmax ) of each sphere, the SUV of the border of each sphere ( SUVborder ), the mean SUV of a 1 cm region of background (SUVbg) and the diameter (D) of each sphere were measured. SPSS 13.0 software was used for curve fitting and regression analysis to obtain the threshold algorithm. The calculated thresholds were applied to delineate 29 pathologically confirmed lung cancer lesions on PET images and the obtained volumes were compared with the volumes contoured on CT images in lung window. Results The algorithm for defining contour threshold is TH% = 33.1% + 46.8% SUVbg/SUVmax + 13.9%/D ( r = 0.994) by phantom studies. For 29 lung cancer lesions, the average gross tumor volumes ( GTV ) delineated on PET and CT are ( 7.36 ± 1.62 ) ml and (8.31 ±2.05) ml, respectively (t = -1.26, P＞0.05). Conclusion The proposed threshold algorithm for tumor contouring on PET image could provide comparable GTV with CT.

In this study, the standard research methods were applied to account the awards and applications of scientific research achievements of Xiyuan hospital from 2010 to 2014. As for the scientific research awards, each department from Xiyuan hospital was active, but the awards application offices were relatively few, thus the quantity of the awards was decreasing year by year. And the distribution was relatively uneven. The basic characteristics of scientific research awards showed that the National Science and Technology Award was the most difficult award. And other characteristics of scientific research award showed that it was often based on a project with high social recognition and high authority, and with the first researchers were high rank professors. This work cast light on that scientific research management should improve the quality of projects and strengthen exchanges, propaganda and introduction of each project achievement, enhance team establishment as support, and establish a reasonable assessment system for scientific research achievements.

Objective To observe the curative effects and toxicity of low-dose bortezomib plus thalidomide and chemotherapy in treatment of multiple myeloma. Methods 35 patients with initial, refractory or relapsed MM received at least two cycles of treatment with bortezomib at 1.1 mg/m2 intravenously on days 0,3, 7, and 10, and by daily oral thalidomide escalated from 50mg to 150 mg and chemotherapy. The chemotherapy regimens included MP, VAD and AD regimen which was chosen according to the status of patients. Results After a median follow-up of 20 months, the overall response rate was 82.8 %, complete remission (CR)48.6 %, very good partial remission (VEPR) 17.1%, and partial remission 17.1%. The 3-year PFS and OS were 60.92 % and 72.41% separately. ORR and OS were same in initial and refractory or relapsed MM patients. Grade 3 or 4 adverse events including debility (3/35), nausing and vomiting (8/35), constipation (4/35), peripheral sensory neuropathy (3/35), neutropenia (10/35) and thrombocytopenia (12 %) were observed.Conclusion The regimen of low-dose bortezomib plus thalidomide and chemotherapy is a highly effective and safety regimen for MM patients. The maintenane therapy with thalidomide may prolong PFS.

OBJECTIVE:To analyze the cost-effectiveness of two regimens in the treatment of chronic hepatitis B fibrosis. METHODS:112 cases of chronic hepatitis B fibrosis were divided into Compound biejia ruangan tablet group (group A,n=56) and Anluo huaxian pill group(group B,n=56). Both groups received Entecavir dispersible tablets combined with relevant Chinese patent medicine. The liver fibrosis index and transient elastography of 2 group were detected before and after treatment,TCM symp-tom score and effective rate calculation were conducted to compare the cost-effectiveness of 2 groups. RESULTS:The cost,effec-tive rate and cost-effectiveness ratio of group A were 9 227.10 yuan,74.11% and 12 451;those of group B were 8 202.90 yuan, 69.28%and 11 840;incremental cost-effectiveness ratio was 21 205. Group B showed a better cost-effectiveness. Result of sensitiv-ity test was same to that of cost-effectiveness analysis. CONCLUSIONS:The cost-effectiveness of Anluo huaxian pill combined with Entecavir dispersible tables is better than Compound biejia ruangan tablet combined with Entecavir dispersible tables in the treatment of chronic hepatitis B fibrosis.

Radiation-induced brain injury is a neurological injury caused by radiation therapy of head and neck tumors. The pathogenesis is still unclear. It is hypothesized that immune cells play an important role in radiation-induced brain injury. The excessive activation of microglia in the central nervous system and the migration of peripheral immune cells into the brain collectively promote the incidence and development of radiation-induced brain injury. In this article, the immunological mechanism underlying the radiation-induced brain injury was reviewed.
