Objective To study the pharmacokinetic characters of cyclosporin A(CsA) in aqueous humor in rabbit after implanting different dosages of CsA in eyes and to provide a theoretical basis for the treatment of after cataract. Methods ECCE was performed in all rabbit eyes. CsA-MS was injected into the anterior chamber and the capsular bag in left eyes as expression group and MS was given in the same way in right eyes as control group. The concentration of CsA in the aqueous humor was monitored with high-performance liquid chromatogram. The follow-up period was 4 weeks. The samples were separated on a C18 column at 60℃ and detected at 210nm. The mobile phase was acetonitrile-water (67∶33). Results The correlation analysis showed a positive correlation within the range of 0.13-1.25mg/L (r=0.9951) and the detection limit was 0.13mg/L. The accuracy was 95.91% and the inter-day and intro-day precision was less than 5%. CsA in aqueous humor sustained a high concentration within 2 weeks. There were no significant differences in t1/2Ka and CL between the two dosage groups. AUC and Cmax increased in a dose-dependent manner. Conclusion The sustain-released CsA ophthalmic gels provided significant ocular bioavailability in rabbit eyes and they can reach the therapeutic dose in order to inhibit after cataract.

Objective To investigate the effects of hippocampal?sparing intensity?modulated radiotherapy ( IMRT) on dose distribution of target volume and organs at risk ( OARs) in locally advanced nasopharyngeal carcinoma. Methods A retrospective dosimetric analysis was performed among 11 patients with locally advanced nasopharyngeal carcinoma. The MONACO ? v5. 10 Treatment Planning System was used to design three treatment plans:routine volumetric modulated arc therapy ( VMAT ) , hippocampal?sparing VMAT, and nine fixed?fields IMRT. The D98%, D50%, D2%, Dmean , conformity index ( CI ) , and homogeneity index (HI) of planning target volume (PTV) and PTVnx as well as dose distribution of the hippocampus and OARs were evaluated. Using single factor analysis of variance,two group comparative was LSD or paired t?test. Results For the above three plans,the D2% values of PTVnx were ,7 513,and 7 462 cGy,respectively (P=0. 016);the D98% values of PTV were 5837,5812,and 5914 cGy,respectively (P=0. 029);the average D2% values of PTV were 7 399,7 380,and 7 333 cGy,respectively ( P=0. 047);the HI values of PTV were 0. 239,0. 241,and 0. 220,respectively (P=0. 016);the V10 values of the brain stem were 97. 2%,88. 1%,and 90. 3%,respectively ( P=0. 001);the V20 values of the brain stem were 74. 2%, 62. 3%,and 67. 1%,respectively ( P=0. 032);the V30 values of the brain stem were 50. 9%,35. 8%,and 45. 5%, respectively ( P= 0. 020 );the V40 values of brain stem were 24. 4%, 14. 4%, and 23. 3%, respectively ( P=0. 018);the Dmean values of hippocampus were 1 518,899,and 896 cGy,respectively ( P=0. 000);the D40% values of hippocampus were 1 379,642,and 639 cGy,respectively ( P=0. 000);the V10 values of the hippocampus were 54. 1%,25. 1%,and 3. 8%,respectively ( P=0. 000);the V20 values of the hippocampus were 26. 2%, 12. 6%, and 12. 0%, respectively ( P=0. 001 ) . Conclusions Hippocampal?sparing VMAT and nine fixed?fields IMRT can significantly reduce the dose to the hippocampus without affecting dose distribution of target volume and OARs. VMAT may be superior to IMRT because VMAT can simultaneously reduce the dose to the brain stem.

Objective To explore the clinical characteristics and diagnosis of Epstein-Barr(EB) virus encephalitis(EBE) in children. Methods The verification of EBE was based on detection of EBV DNA in cerebrospinal fluid (CSF) by fluorogenic quantitative PCR(FQ-PCR) and Nest-PCR. The clinical and CSF changes of 27 EBE cases and 26 controls were analyzed and compared. Results EB-DNA in CSF by FQ-PCR of 13 cases of EBE was (2.82?2.03)?10 3copies.There was no significant difference in clinical manifestations between EBE and HSE groups, except that WBC in CSF of EBE was lower than those of HSE.Conclusions EBE is not infrequent, about 10 % of encephalitis in children. EBE is always present independently, which is not a complication of infectious mononucleosis(IM).Detection of EBV-DNA in CSF is a sensitive and specific test for diagnosing of EBE. Early treatment may be beneficial to the prognosis of EBE.

Acetabular is an important human joint for weight bearing. Quadrilateral plate is a crucial structure of medial acetabulum with special morphology and important function. Quadrilateral plate fractures are common fracture in acetabulum. Quadrilateral plate fracture is hard to expose and reduction because it is in the medial of acetabulum. At the same time,the bone in the quadrilateral plate is not easy to fixed for thinning bones and adjacent to the articular cavity. The operator should know well about the anatomy and choose the suitable internal fixation. After quadrilateral plate fractures, the femur head maybe displace medially even break into pelvis. That make reduction and treatment always be a challenge. With different kinds of fractures,the efficacy of treatment is not the same. This paper intend to review the relation of anatomic features,approaches, internal fixations, key point of treatment and efficacy.
