Objective To investigate the possible role and mechanism of the neurotoxic effect of dexamethasone on adult rats after having focal cerebral ischemia. Methods The rat model of focal cerebral ischemia was established by permanent middle cerebral artery occlusion (MCAO) One hour after ishemia,the experimental groups were treated with dexamethasone (5 mg/kg) while the control groups were treated with saline TUNEL staining and In-suit RT-PCR were used to show the changes of apoptosis and the expression of Fas mRNA at ipsilateral cerebral hemisphere. Results TUNEL positive cells were present in a time from 48 h to 72 h, localizing at peripheral ischemic area The expression of Fas mRNA at peripheral ischemic area in control groups began at 12 h, peaked at 24 h, and decreased to a lower level at 48 h and 72 h, and returned to the baseline at 120 h Treatment with dexamethasone after ischemia made apoptosis present at 24 h and the number of TUNEL positive cells at 48 h exceeded that in the control group at 48 h ( P

Objective To study the expression of TGF ? 1 protein and the changes of microglia of adult rats' brain treated with dexamethasone following permanent focal cerebral ischemia as to elucidating the neurotoxic effect of dexamethasone. Methods The adult rat's models of permanent focal cerebral ischemia were established by permanent middle cerebral artery occlusion.One hour after ischemia experimental groups were treated with dexamethasone (0.5 mg?kg -1?d -1) where as the control groups were treated with saline. The size of infarct was detected by Q570 image analysis system. Immunohistochemistry and picture analyses were performed to observe the expression of TGF ? 1 protein. The microglia was demonstrated by histochemical staining with isolectin-B4.? Result Dexamethasone treatment after ischemia increases the infarct volume significantly. The expression of TGF ? 1 and the changes of microglia were mainly located at the border zone of the infarct. The accumulation of the isolectin-positive microglia began at 12 h,peaked at 2d, decreased at 5 d. The densities of microglia in the groups treated with dexamethasone after ischemia decreased significantly at 12 h,24 h and 3 d as compared with the control groups, and disappeared at 5 d.The expression time-course of TGF ? 1 protein was two-phase. The first peak of expression was at 6 h; the second was from 24 h to 72h. The significant decrease in expression of TGF? 1 protein in rats treated with dexamethasone was observed at 6 h,24 h and 72h compared with that of control group. Conclusion The exceeding inhibition of the response of microglia and the two-phase expression of TGF ? 1 protein at the border zone of infarct may play a role in the neurotoxic effect of dexamethasone on cerebral ischemia.

BACKGROUND:Studies have shown that bone loss can lead to a series of diseases, such as osteoporotic fractures, thus seeking to increase bone mass has become a goal of the majority of researchers.
OBJECTIVE:To summarize the current studies of improving bone mass by using stem cel transplantation, hoping to the extensive application of stem cel transplantation in the clinical treatment of osteoporosis as early as possible.
METHODS:A computer-based search of PubMed and CNKI was performed by the first author to retrieve articles relevant to stem cel therapy for osteoporosis published from January 1997 to October 2014. The keywords were“to improve bone mass, regenerative medicine, bone marrow mesenchymal stem cel transplantation, stem cel therapy”in Chinese and English, respectively, which appeared in the title, abstract or keywords. Articles published recently or in authoritative journals were preferred, and final y 28 articles were included in result analysis.
RESULTS AND CONCLUSION:Bone marrow mesenchymal stem cel s which are isolated and cultured easily can proliferate rapidly and have multi-lineage differentiation potential. Studies have shown that the osteogenic differentiation of bone marrow mesenchymal stem cel s can real y improve bone mass, and obtain more achievements in the treatment of orthopedic disorders. This new cel therapy can help to accelerate bone healing and reduce treatment time, offering a new therapeutic choice for orthopedic surgery, plastic surgery, oral and maxil ofacial surgery, and therefore, it has broad application prospects.

ObjectiveThe aim of this study was to evaluate and compare the surgical outcomes of endoscop ic and conventional open thyroidectomies in patients with thyroid disease.Methods116 patients with tyroid tumor were enrolled.56 patients underwent endoscopic thyroidectomy ( endoscopic group ),and 60 patients underwent conventional open thyroidectomy( conventional group).We analyzed the patients' clinic characteristics,surgical outcomes and complications between the two groups.ResultsThe blood loss was less in the endoscopic group than the open group[( 16.8 ± 9.6) ml vs ( 24.9 ± 14.2 ) ml,t =- 2.427,P ＜ 0.05].The degree of satisfaction for cosmetic outcome in endoscopy group( 96.4％ ) was higher than that in conventional group ( 16.7％ ) ( x2 =74.508,P ＜ 0.01 ).There was no significant difference in the operating time,volume of drainage and postoperative hospital stay between two groups,and there was no significant difference in the skin ecchymosis,redness and swelling and postoperative pain between two groups( all P ＞ 0.05).No severe postoperative complication was encountered,such as injuries of the re current or superior laryngeal nerve,parathyroid gland injury or massive hemorrhage.ConclusionEndoscopic thyroidectomy has less blood loss,mini-open and excellent cosmetic benefits compared with conventional open thyroidectomy.

OBJECTIVETo investigate the feasibility and effectiveness of modified Stoppa approach in treatment of bilateral pubic fractures of pelvic.

METHODSThe therapeutic effects of 16 patients with bilateral pubic fractures treated through the modified Stoppa approach from January 2010 to January 2014 were summarized and analyzed, involved 11 males and 5 females with an average age of 40.5 years old ranging from 17 to 59 years. According to Tile classification, there were 8 patients with type A, 6 with type B and 2 with type C. For 16 pelvic fractures, the modified Stoppa approach was used exclusively 11 cases, in combination with the iliac fossa approach in 4 cases, and in combination with the posterior approach in 1 case. The operation incision length, operation time , intra-operative blood loss and postoperative complications were observed. The fracture reduction and post-operative function were assessed by Matta criteria and Majeed system respectively.

RESULTSThe incision length of the modified Stoppa approach ranged from 8 to 10 cm (averaged in 9 cm). The operation time ranged from 75 to 135 minutes (averaged in 95 minutes). The intra-operative blood loss ranged from 400 to 900 ml (averaged in 600 ml). Sixteen patients were followed up from 7 to 18 months (averaged in 12.5 months). The fractures were all healed, the fracture healing time was 2.7 to 5 months (means 3.1 months). There were no infections, ectopic ossification, screw loosening, plate breakage and lateral ventral syndrome. According to Matta criteria for pubic fracture reduction, the result was excellent in 9 cases, good in 6, fair in 1. The Majeed function scores at 6 months after operation was 85.32±8.50; the result was excellent in 8 cases, good in 6 cases, fair in 2 cases.

CONCLUSIONThe modified Stoppa approach has characteristics of convenience and directness of incisions, clear operation field, easy reduction, few complications and fast recovery , it is an ideal choice in surgical treatment of bilateral pubic fractures.

OBJECTIVETo evaluate the risk factors and study the methods of prevention and treatment for the ruptures of aneurysms in keyhole minimally invasive approaches.

METHODSFrom 1999 to 2005, 115 cases of intracranial aneurysms were divided into 2 classes according to the risk factors of aneurysm rupture. Forty-three cases of lower risk underwent microsurgical procedures as keyhole approaches, including pterional approach in 20 cases, supraorbital approach in 18 cases, interhemispheric approach in 5 cases. Seventy-two cases, rest of microsurgical procedures, were performed as conventional craniotomy, including pterional approach in 31 cases, supraorbital approach in 11 cases, interhemispheric approach in 7 cases, pterional-supraorbital in 10 cases, pterional-interhemispheric in 6 cases, supraorbital-interhemispheric in 4 cases, pterional-supraorbital-interhemispheric in 3 cases.

RESULTSSix aneurysms leaked and 3 ruptured (rupture rate 7.0%) treated with keyhole approaches during operations. No one died by keyhole approaches. Eighteen aneurysms leaked and 9 ruptured (rupture rate 12.5%) treated with conventional approaches during operations. Two patients died by conventional approaches.

CONCLUSIONSKeyhole approaches as a time-saving, trauma-reducing procedure could improve the postoperative outcomes, but these approaches still exist probability of aneurysm rupture. It is possible that keyhole-bone flap becomes a limitation to deal with huge or ruptured aneurysms. And it is important to make a specially preventive strategy for aneurysm rupture.
