[Objective] To study the effect of anti-infective reconstituted bone xenograft(ARBX)on treating chronic hematogenous osteomyelitis as one-stage grafting.[Method]ARBX was used to treat 24 cases of chronic hematogenous osteomyelitis as one-stage grafting after debridement since September of 2001,17 cases of which were followed up for an average period of 34 months(range,12 to 79 months).[Result]Except 1 case failed to cure,and 1 resulted in recurrence of infection,and 1 with large segmental bone defect nonunion post-operatively,other 14 cases were cured,the cure rate was 82.4% which was better than traditional therapy.[Conclusion]ARBX has high osteoinductive activity and enhanced anti-infective capability,which enables it to be used as primary grafting to treat chronic hematogenous osteomyelitis.

Objective:To study the cognitive function and brain white matter fiber change in major depressive patients prior and post-treatment.Methods:Eleven major depressed patients were given antidepressants for 10 weeks, and their conditions were evaluated using 24-item Hamilton Depression Scale(HAMD).The cognitive function was determined by using Wisconsin Card Sorting Test(WCST),part of Wechsler memory scale and diffusion tensor ima- ging(DTI)was scanned before and after treatment.11 healthy people as control group were involved and given the same tests at the same time.Results:(1)The WCST scores of patients increased significantly after treatment(prior treatment Cc:1.6?1.6,Re:67.9?20.0,Rpe:51.5?24.8;post treatment Ce:4.0?2.1,Re:43.2?18.8,Rpe:22.8?16.0,P=0.001/0.000/0.003).There was no difference in number sequence memory in Wechsler memory scale.No difference was found between patients after treatment and control group in either WCST or number sequence memory.The patients made significant improvement in the total score of HAMD after treatment(16?14/54?13,t=6.60,P

Objective To establish a desirable quantitative assay system to evaluate the correlation between surgical manipulation and micrometastasis in primary esophageal cancer patients.Methods 118 pe- ripheral blood samples from 40 esophageal cancer patients undergoing radical resection were collected before surgery(B-1),immediately after surgery(B0)and at the third day postoperatively(B+3).Based on real-time quantitative reverse transcription-PCR,carcinoembryonic antigen(CEA)mRNA gene was used in the detec- tion.12 patients with benign tumor and 13 healthy volunteers were collected as negative control groups.Re- sults The median of CEA mRNA copies at B-1,B0 and B+3 were 1592,13 314 and 6221 copies/ml blood, respectively.CEA mRNA expression levels were found to be significantly higher at both B0 and B+3 than that of B-1(P=0.0001 and 0.0209,respectively).No significant difference was found between B0 and B+3(P= 0.4396).Conclusion Surgical manipulation on esophageal cancer patients increases the probability of mi- crometastasis.Therefore,adjuvant therapy is needed during perioperative stage.

Objective To study the effect of glucocorticoid on serum interleukin(IL)-1,IL-6,transforming growth factor-?_1(TGF-?_1) and tumor necrosis factor alpha(TNF-?) in children with primary nephrotic syndrome(PNS).Methods The levels of cytokines on serum were compared in 3 different patho-type,and IL-1,IL-6,TGF-?_1 and TNF-? in serum were detected using enzyme-linked immunosorbent assay(ELISA) in 25 children with PNS before and after treatment with glucocorticoids.Results Significant difference of IL-1,IL-6,TGF-?_1 and TNF-? were found between the two group before and after the treatment(P0.05).The level of TGF-?_1 in MCD was lo-wer than that in MsPNG,FSGS before and after the treatment(P0.05),and the level of it in FSGS was higher than that in MsPNG after the treatment(P

OBJECTIVETo evaluate the curative effect and surigical skills of reconstruction intramedullary nailing in the treatment of ipsilateral femoral neck and shaft fractures.

METHODSFrom January 2007 to January 2013, 13 patients with ipsilateral femoral neck and shaft fractures were treated by reconstruction intramedullary nailing including 11 males and 2 females with an average age of 38.9 yeas old ranging from 25 to 53 years old. For femoral neck fractures,10 cases were basilar neck fracture, 3 were transcervical fractures and according to Garden classification,10 were type II, 2 were type III and 1 was type IV. For feormal shaft fracture, 5 were type I, 4 were type II, 3 were type III and 1 was type IV according to Winquist classification. The location of all 13 feormal shaft fractures were all in the uper 3/4 of the feormal shaft. Complications and postoperative function were recorded and evaluated.

RESULTSEleven patients were followed up for 23.45 months (12 to 36 months). Time from injury to operation was 5.9 days in average. Malunion of femoral neck fracture happened in 1 patient, nonunion of femoral shaft fracture happened in 2 patients. NO femoral head osteonecrosis, infection and malunion of femoral shaft fracture happened. According to Friedman-Wyman classification, 8 cases get good result, 2 get faii and 1 get poor.

CONCLUSIONReconstruction intramedullary nailing is a good choice for the ipsilateral femoral neck and shaft fractures with the advantages of less soft-tissue trauma and complications.

Objective To study the safety and efficacy of transhepatic arterial infusion embolization using microspheres combined with lipiodol for treatment of hepatocellular carcinoma(HCC).Methods Transhepatic arterial chemoembolization(TACE)was performed with 1-2 ml 300-500?m mierospheres and 10-20 ml lipiodol for treatment of HCC.Changes of liver function,AFP,responses of tumor and complications related to embolization were analyzed before and after TACE.Results Thirty six patients with HCC were enrolled into this study.After TACE,patients' liver function got worsen and tumor size decreased significantly(P＜0.05).Conclusion TACE with use of microspheres combined with lipiodol is an effective treatment for HCC,but should be taken carefully to avoid hepatic failure.

In temporomandibular disorders (TMD), pain takes place when neuropeptides stimulate synovial tissue to produce several cytokines such as interleukin (IL)-1β, IL-6 and tumor necrosis factor (TNF)-α, which activate neurons and glia of synovial membrane at the bilaminar regions of temporomandibular joint (TMJ). It has been reported that, after neurogenic differentiation, the synovial mesenchymal stem cells (SMSCs), deriving from TMJ, possess the same cytological features as the neuronal cells. This study examined the ability of substance P (SP) and calcitonin gene-related peptide (CGRP) to stimulate SMSCs and neurogenic SMSCs secreting inflammatory cytokines during TMD, evaluated the mutual effects of inflammatory cytokines and neuropeptides and tested the analgesic effect of hyaluronic acid (HA). The levels of IL-1β, IL-6 and TNF-α in SMSCs and neurogenic SMSCs in the presence of neuropeptides were measured by ELISA. SP and CGRP produced by SMSCs and neurogenic SMSCs were determined by RT-PCR and Western blotting. The results showed that the expression of SP and CGRP was significantly enhanced in the neurogenic SMSCs in response to IL-1β, IL-6 and TNF-α, and the effect was remarkably inhibited by HA. IL-1β, IL-6 and TNF-α, in return, could be enhanced in the neurogenic SMSCs upon stimulation by SP and CGRP. Neuropeptides and inflammatory cytokines might work mutually on the TMD pain. The HA-mediated analgesic effect may be implicated in the inhibition of SP and CGRP expression in neurogenic SMSCs.
