Objective To explore the clinical features and treatment of eosinophilic lymphoid granuloma(ELG) in children,in order to increase understanding of the disease.Methods Clinical features,laboratory examination,pathological examination,treatment and the-(rapeutic) effect of 5 patients with ELG were retrospectively studied,and the related literature were reviewed.Results Five cases were all boys.They all presented many subcutaneous swellings and lymphadenopathy.A case among them was associated with nephrotic syndrome,and 2 cases had the complication of eczema repeatedly,and 1 case ever had 2 times episodes of asthmatiform bronchitis.All of them had no hepatomegaly and splenomegaly,physically was well developed.Only chemotherapy was supplied to all the patients.During the course of therapy,4 cases among them recurred.After that,they were successfully treated with irradiation of lesion or cyclosporine(CsA).Conclusions ELG in children is as same as adult in clinicopathological features.It tends recur only with chemotherapy.We can get better curative effect with the synthetic treatment of chemotherapy,radiotherapy,operation or oral CsA and so on.

Objective To evaluate the overall effect of transsphenoidal microsuegery for 23 patients with non-adenomas disease intrasellar region.Methods A toal of 23 patients with non-adenomas disease in- trasellar region,7 cases of Rathke's cleft cyst,3 cases of craniopharyngiomas,2 cases of meningiomas,2 ca- ses of pituitary tuberculous granuloma,5 cases of pituitary abscess,2 cases of empty sella,2 cases of chord- mas,were treated via sublabio-septo-sphenoidal microsurgery.Results There were among the 23 patients, groos total removal of the disease were achieved in 14 cases,subtotal removal in 7 cases,and partial removal in remain 2 cases.Diminished visual activity and visual field defects were improved in 13 cases.Menstrual disorder in all female cases and sexual disturbance in male were improved.There was no death in group. Conclusion Microsurgical technique via transsphenoidal approach is a safe and effective one for the treatment of patients with non-adenomas disease intrasellar region.

Objective:To examine the expression of odontoblast related proteins in dental pulp stem cells(DPSCs)induced by BMP-7.Methods:DPSCs were cultured in the common culture medium or medium supplemented with 1 00 ng/ml BMP-7.Electron microscope,CCK8 and immunohistochemical staining were carried out to estimate the cell morphology and differentiation.Results:In-duced by BMP-7,the morphology of DPSCs was not changed,the proliferation of DPSCs was slower than that of the cells without BMP-7 treatment.DPSCs were negative for the expression of DSPP,DMP-7 and ALP.However,DPSCs were found strongly positive for DSPP,DMP-7 and ALP after the induction of BMP-7.Conclusion:BMP-7 induction may promote the differentiation of DPSCs.

OBJECTIVETo compare the clinical effects between hip anterior S-P approach combined with iliac bone flap transplantation with deep circumflex iliac artery and posterior K-L approach combined with quadratus femoris bone flap transplantation for the treatment of femoral neck fracture of Garden III-IV in young and middle-aged patients.
METHODSFrom January 2004 to January 2011,46 patients with femoral neck fractures were treated by two kinds of operation. Among them, 20 cases were treated with anterior S-P approach combined with iliac bone flap transplantation with deep circumflex iliac artery, included 12 males and 8 females with an average age of (32.1 ± 7.3) years old, involved 12 cases of Garden III and 8 cases of Garden IV. The other 26 cases were treated with posterior K-L approach combined with quadratus femoris bone flap transplantation, included 20 males and 6 females with an average age of (37.8 ± 6.9) years old, involved 16 cases of Garden III and 10 cases of Garden IV. The index of hospitalization (hospitalization time, total cost, operative time, intraoperative blood loss, postoperative complications), the quality index of operation (fracture reduction, position of internal fixation, fracture healing time, nonunion and femoral head necrosis) of two groups were observed and compared. Hip joint function were evaluated by Harris score.
RESULTSAll patients were followed up from 28 to 41 months with an average of 36 months. The intraoperative blood loss of group S-P (92.3 ± 10.4) ml was less than that of group K-L (132.4 ± 11.2) ml, there was significant difference between two groups (P < 0.05). The operation time of group S-P (81.4 ± 9.2) min was more than that of group K-L (67.1 ± 4.5) min, the difference was statistically significant (P < 0.05). One case in group S-P and 9 cases in group K-L appeared postoperative complications, there was significant difference between two groups (P < 0.05). The fracture healing time of S-P group (83.5 ± 7.3) d was shorter than that of group K-L (103.2 ± 12.6) d, there was significant difference between two groups (P < 0.05). At 30 months after operation, there were significant difference in Harris scoring between two groups (P < 0.05).
CONCLUSIONAnterior S-P approach combined with iliac bone flap transplantation with deep circumflex iliac artery for treatment of femoral neck fracture of Garden III-IV of young and middle-aged patients, it has characteristics in clear anatomic and easy to operate. As compared with K-L approach, S-P approach can better reserve residual blood supply of femoral neck. While combining with the iliac bone flap transplantation with deep circumflex iliac artery, it could better reconstruct the blood supply of femoral neck to promote fracture healing.

The objectives of this study are to prepare resveratrol loaded mixed micelles composed of poloxamer 403 and poloxamer 407, and optimize the formulation in order to achieve higher drug solubility and sustained drug release. Firstly, a thin-film hydration method was utilized to prepare the micelles. By using drug-loading, encapsulation yield and particle size of the micelles as criteria, influence of three variables, namely poloxamer 407 mass fraction, amount of water and feeding of resveratrol, on the quality of the micelles was optimized with a central composite design method. Steady fluorescence measurement was carried out to evaluate the critical micelle concentration of the carriers. Micelle stability upon dilution with simulated gastric fluid and simulated intestinal fluid was investigated. The in vitro release of resveratrol from the mixed micelles was monitored by dialysis method. It was observed that the particle size of the optimized micelle formulation was 24 nm, with drug-loading 11.78%, and encapsulation yield 82.51%. The mixed micelles increased the solubility of resveratrol for about 197 times. Moreover, the mixed micelles had a low critical micelle concentration of 0.05 mg · mL(-1) in water and no apparent changes in particle size and drug content were observed upon micelles dilution, indicating improved kinetic stability. Resveratrol was released from the micelles in a controlled manner for over 20 h, and the release process can be well described by Higuchi equation. Therefore, resveratrol-loaded poloxamer 403/407 mixed micelles could improve the solubility of resveratrol significantly and sustained drug release behavior can be achieved.
