Objective To evaluate one-stage arthroscopic reconstruction of anterior crueiate ligament (ACL)and posterior cruciate ligament(PCL)using Achilles tendon-bone allografts. Methods From July 2000 to February 2005.we treated 15 patients(11 males and 4 females)whose ACL and PCL were ruptured at one knee but the eontralateral knee was intact.Their associated meniscus injuries were treated arthroscopically according to established procedures prior to ligament reconstruction.Thirty Achilles tendon-bone allografts were used to reconstruct torn ACL and PCL in 15 knees at one stage.Reconstruction of both ligaments was performed at subacute or chronic phase(>3 to 8 weeks)in 12 casses,and at acute phase in 3 cases(<3 weeks).All knees were graded pre-and postoperatively using the International Knee Documentation Committee(IKDC)and Lysholm scoring systems.At follow-up,functions were evaluated for all patients and compared with those of the contralateral healthy knee. Results All patients were followed up for a minimum of 3 years(mean,38 months).Preoperatively,the IKDC ratings showed all the injured knees were severely abnormal.At final postoperative f0Uow-up,9 knees received a normal rating,5 a nearly normal one and 1 an abnormal one.The differences in Lysholm score were statistically significant (t=15.660,P<0.05)between pre-and postoperative analyses.The most noticeable postoperative complication was a short localized fever coupled with arthroedema in 1 case. Conclusions Achilles tendon-bone allograft offers an alternative for simultaneous arthroseopic reconstruction of ACL and PCL.However,problems inherent in allograft tissues entail further investigation to ensure future application.

Objective To evaluate the clinical effects of emergency neoplasty on corneal penetrating injury. Methods A total of 102 cases of corneal penetrating injury were investigated.The patients underwent micro-trauma technique suture,optical iridectomy,extraction of anterior segment foreign bodies,nepheloid lens removal,and artificial lens implantation.The vision of pre-and post-surgery was compared and relationship between injury location and recovery was analyzed.

OBJECTIVE To investigate the relationship between phenotypes and genotypes of clinical isolates of ESBLs-producing Klebsiella pneumoniae.METHODS Agar dilution method was used to test the MICs of 11 antibiotics against 67 ESBLs-producing K.pneumoniae strains.PCR was performed for amplifying ?-lactamase-encoding genes of SHV-,TEM-,and CTX-M-type,and the PCR products of some strains were cloned and sequenced to identify their gene serotypes.RESULTS With no imipenem-resistant strains among 67 strains,their resistant rates to 10 kinds of antibiotics were 10.45-89.55% The cross-resistant rates to aminoglycosides of 60 strains and to ?-lactams of 44 strains were 88.33% and 40.91%,respectively.The positive rates of SHV-,TEM-,and CTX-M-type for 67 strains were 91.04%,56.72% and 28.36%,respectively,and SHV-12,TEM-1 and CTX-M-3 genotypes were found in 7 strains by cloning and sequencing.CONCLUSIONS Sixty seven strains of ESBLs-producing K.pneumoniae present a clear feature of multi-resistance and cross-resistance to most of antibiotics except imipenem,among them there are 7 strains producing SHV-12 and CTX-M-3 extended-spectrum ?-lactamase coexistent with TEM-1 broad-spectrum ?-lactamase.

Objective To make a survey on common cosmetic allergens, and to provide epidemiological data and clinical evidence for cosmetic allergy. Methods Patch test was performed by using 49cosmetic allergens from a European cosmetic series and 5 Chinese standard screening allergens on 89patients with suspected cosmetic allergic contact dermatitis. Test results were determined according to the International Contact Dermatitis Research Group (ICDRG) recommendation. Results Of the 89 patients, 61(68.5%) showed positive reactions to one or more cosmetic allergens. The most common allergens were fragrances (33.7%), followed by preservatives (30.3%), para-phenylenediamine (25.8%) and amerchol L 101(10.1%). Conclusion Fragrances, preservatives, para-phenylenediamine and amerchol L 101 are dominant causative allergens in patients with cosmetic allergic contact dermatitis.

Objective To investigate the risk factors of delirium in elderly patients with intertrochanteric fracture after internal fixation.Methods The data of 160 patients with intertrochanteric fractures who received internal fixation in our hospital from January 2012 to July 2014 were analyzed retrospectively.The risk factors such as age,sex,preoperative complications,preoperative cognitive function,fracture location,operation mode,operation time,anesthesia method,hospital-to-operation time and intraoperative blood loss were summarized.Results The incidence of postoperative delirium was 28.15％ in postoperative elderly patients with intertrochanteric fractures.Univariate analysis showed that delirium had correlated with preoperative cognitive impairment,preoperative preparation time,serum sodium,fentanyl,atrial fibrillation,anesthesia method,operation time and perioperative blood loss (P ＜ 0.05).The multivariate Logistic regression analysis showed that the independent risk factors of postoperative delirium were preoperative cognitive dysfunction,operative time more than 2 hours and preoperative preparation time more than 4 days.Conclusion The occurrence of postoperative delirium was associated with anesthesia method,cognitive deficits,preoperative preparation time and perioperative blood loss.The anesthesia method which had less effect on the whole body condition and less time of operation preparation can decrease the occurrence of postoperative delirium in a certain extent,which is conducive to improving the prognosis.

Aim To investigate the effects of maternal chronic aluminum exposure on memorial behaviour and hippocampal intracellular Ca2+ concentration ([Ca2+]i)on their offspring after the induction of LTP(long-term potentiation). Methods Adult Wistar rats (150~200 g) were exposed to aluminum by drinking distilled water, the concentration of AlCl3 is 0.015 mol?L-1(2 g?L-1) and 0.03 mol?L-1(4 g?L-1) aluminum chloride (AlCl3) solution, respectively, for 30 days prior to mating and during the whole gestation and suckling period. Their offspring were distributed into three experimental groups: control group; two exposed groups (represented by 0.2%-Al and 0.4%-Al ) administrated aluminum exposure ended at postnatal day 21. The brain tissue and blood aluminum levels were measured by Atomic absorption spectrometry (AAS). Memorial ability of the offspring was tested by Step down test.[Ca2+]i was measured by the technique of Fura-2/AM calcium ions fluorescence indicator. Results The mean aluminum content in blood and brain tissue was significantly higher than the control group(P0.05), but was significantly decreased in 0.4%-Al exposed group(P

Objective To study whether bellidifolin has rehabilitation effect on injured sciatic nerve rats,and whether ciliary neurotrophic factor (CNTF) is involved in this mechanism.Methods 225 male wistar rats were made to be sciatic nerve injured models,with right sciatic nerve being cut and sewed under microscopy,left sciatic being sham.Rats were randomly divided into control group,bellidifolin 25 mg,50 mg,75 mg groups and mecobalamin group,with 45 rats in each group.Rats in control group were just injected sodium chloride,others were intra-peritonealiy injected different doses of bellidifolin and mecobalamin after operation.Results Three weeks after operation,SFl of control group,mecobalaming group,bellidifolin 25 mg,50 mg and 75 mg group were-84.35± 4.87,-45.20±2.30,-70.42±4.21,-57.73±3.46 and-64.38±4.38 respectively.Compared with control group,others showed significant differences (P＜0.05).There were statistically differences between bellidifolin groups and mecobalaming group(P＜0.05).Within bellidifolin groups,50 mg group showed difference compared with 25 mg and 75 rg groups(P=0.031).TSW results also showed differences among bellidifolin groups,control group and mecobalaming group.There were statistical differences among bellidifolin groups(P＜0.05).Each groups with immunohistochemistry analysis,CNTF expression showed statistically differences among bellidifolin 50 mg group and 25 mg,70 rg groups,Bellidifolin 50 mg group was higher than others(P＜0.05).Conclusion Bellidifolin can promote the recovery of injured sciatic nerve,especially the concentration of 50 mg bellidifolin,and CNTF is involved in the rehablitation process.

Objective To construct the RNA interference eukaryotic expression vector targeting human centromere protein-I (CENP-I) and to observe its effect on the growth of human embryo kidney 293 cells (HEK 293). Methods The expression vectors of pGenesil-1/CENP-I-siRNA-1. pGenesil-1/CENP-I-siRNA-2 and pGenesil-1/CENP-I-siRNA-3 were constructed by gene recombination and then were transfected into the HEK293 cells by liposome. The expressions of CENP-I at the protein and mRNA levels were detected by Western blotting and fluorescence quality PCR (FQ-PCR). The effective vector and the best transfection time were selected. The growth and the cell cycle of the transfected cells were assessed by MTT assay and flow cytometry. Giemsa was used to stain the transfected cells to calculate the mitotic index. Results Sequence-specific siRNAs targeting CENP-I significantly down-regulated the expression of CENP-I in HEK293 cells. The recombinant plasmid of pGenesil-1/CENP-I-siRNA-3 was the effective vector. After transfecting for 72 h the best inhibited efficiency was achieved. In CENP-I-siRNA transfected cells,the rate of cell growth was decreased markedly. Cells at G 2/M phase and the mitotic index were increased conspicuous compared with the cells transfected with the blank vector or untransfected. Conclusion Down-regulation of CENP-I in HEK293 cells by sequence specific siRNA delays the cell growth and postpones the cell division.

BACKGROUND:Bone marrow mesenchymal stem cels play an osteogenic role under the assistance of scaffold materials. The scaffold cannot only deliver the cels to the bone defect area, but also act as a new bone growth framework. Colagen-chitosan composite is one of ideal scaffold materials in bone tissue engineering, which has osteoinductive ability and better osteogenic ability than conventional scaffolds. Bone transport technology has been widely used in the clinical repair of long bone defects, but it has some deficiencies, such as slow osteogenesis, long time for external fixation and nonunion. How to further accelerate bone formation and reduce complications has become the current problem to be solved. Here, it is hypothesized that bone marrow mesenchymal stem cels/ colagen/chitosan composite scaffold can increase the therapeutic effect of bone transport in the repair of tibial bone defects.
METHODS/DESIGN:This study is a randomized controled animal experiment, includingin vitro andin vivo tests.In vitro test: Bone marrow mesenchymal stem cels are isolated from the bone marrow of New Zealand rabbits aged 1-2 months, and passaged to the third generation. Then, cel suspension is added onto the colagen-chitosan scaffold to construct the bone marrow mesenchymal stem cels/colagen/chitosan composite scaffold.In vivo test: Twenty-four New Zealand rabbits at 3-4 months are selected and randomly assigned to receive bone transport, scaffold implantation, bone transport+scaffold implantation, respectively. The primary outcome measures are the growth of implant materials and bone defect interface, X-ray detection of bone defect repair, hematoxylin-eosin staining and scanning electron microscope observation of bone formation in the bone defect region, immunohistochemical detection of type I colage expression in the osteogenic region, scanning electron microscope observation of interface bonding between implant materials and host bone, ultrastructure and bone formation.
DISCUSSION:The results from this animal experiment wil help to determine the feasibility of bone marrow mesenchymal stem cels/colagen/chitosan composite scaffold to accelerate bone repair during bone defect repair using bone transport technology.
