Objective To compare the clinical outcome of external fixation device with Kirschner wire or fragment fixation pin with mini plate and screw fixation in treatment of metacarpal and phalangeal articular fracture dislocation. Methods From October 2002 to March 2008, 106 patients with metacarpal and phalangeal articular fracture dislocation were randomly divided into A and B group. The 53 patients in A group were treated with external fixation device with Kirschner wire or fragment fixation pin. There were thumb injury in 24 cases, fracture-dislocation of proximal interphalangeal joint(PIP) in 36 cases, fracture-dislocation of metacarpophalangeal joint (MP) in 17 cases. The 53 patients in B group were treated with mini plate and screw fixation. There were thumb injury in 22 cases, fracture-dislocation of PIP in 30 cases, fracture-dislocation of MP in 23 cases. Duncan rating criteria were used to compare finger range of motion. Results The mean follow-up of 16.8 and 17.5 months in A group and B group. According to Duncan rating criteria, there were excellent in 33 cases, good in 16, fair in 3, and poor in 1 case. The excellent and good rate was 92.5% in A group. There were excellent in 30 cases, good in 17, fair in 5, and poor in 1 case. The excellent and good rate was 88.7% in B group. In A group, 1 case of wound infection was found. The average arc of motion of thumb joint was 134°±21° while the average arc of motion of other fingers was 248°±19°. In B group, no wound infection occurred. The average arc of motion of thumb joint was 122°±18° while the average arc of motion of other fingers was 225°±17°. Conclusion External fixation device with Kirschner wire or fragment fixation pin was better than the application of mini plate and screw fixation in treatment of metacarpal and phalangeal articular fracture-dislocation.

Objective To examine whether microinjectlon of morphine into the rat thaiamle nucleus submedlus (Sin) could depress the bee venom (BV)-induced nociceptive behaviours. Methods In inflammatory pain model induced by BV subcutaneous injection into rat unilateral hind paw, the inhibitory effects of morphine microinjection into thalamic nucleus suhmedius (Sin) on the spontaneous nociecptlve behavior, heat hyperalgesia and tactile ailodynia, and the influence of naioxone on the morphine effects were observed in the rat. Results A single dose of morphine (5.0 μg, 0. 5μL) applied into the Sm ipsilaterni to the BV injected paw significantly depressed the spontaneous paw flinching response. Morphine also significantly increased the heat paw withdrawal iateneies in the bilateral hind paw and the tactile paw withdrawal threshold in the ipsilnteral hind paw 2 hours after BV injection. All these depressive effects could be effectively antagonized by pre-treatment with the opiuld receptor antagonist naloxone (1.0μg, 0. 5μL) in the Sm 5rain prior to morphine administration. Naloxone alone injected to the Sm had no effect on the BV-induecd nociceptive behavior. Conclusion These results suggest that Sm is involved in opioid receptor-mediated antt-nociception in the rat with the BV-induced inflammatory pain. Together with results from previous studies, it is likely that this effect is produced by activation of the Sm-ventrolateral orbital cortex-periaqueductal gray pathway, leading to activation of the brainstem descending inhibitory system and depression of the nodceptive inputs at the spinal cord level.

Objective To analyze indications,complications and outcomes of amputation.Methods A total of 15 patients undergone amputation in field or at tent hospital were collected for analy-zing injury severity,place where amputation was done,whether open or closed amputation and stitch re-moval time. Results There were 9 males and 6 females.at an average age of 32 years(11-51years).There were 16 amputations including Gustilo IIIB in 2 patients, Gustilo IIIC in 9 and Tscheme Ⅲin 5 according to Gustiln classification or Tscheme classification.Four patients who received amputation in field or at tent hospital developed infection and had to receive amputation again at a higher level on the limb and drainage of open wounds because of a higher infection rate due to the amputation location.Ten patients received first amputation at higher levels with open wound at station hospital but only 2 manifested infected incision.High level amputation with one stage closure was done in 1 patient who was infected and suppurated after operation and even developed bacteremia. Conclusions Infection rate following am-putation 4n field and tent clinics is rather higher,so secondary open amputations should be performed at a higher level as soon as possible.One-time and high-level open amputation plays an important role in treat-ment of severe lower limb injuries following earthquake.

Objective To investigate the discrepancy of aldosterone synthesis process and potential regulation abnormality between aldosterone-producing adenoma(APA) and normal adrenal(NA) with microarray. Methods cRNA probes labelled with biotin were prepared from mRNA of APAs(APA group,n=10) or NAs(control group,n=7).The probes were hybridized with oligonucleotide microarray of target gene expression profile.Expression levels were read from the fluorescent intensity scanned.The difference of gene expression profile was analyzed by computer software.Differentially expressed genes were verified by real-time RT-PCR. Results Compared with control group,97 genes were up-regulated and 168 genes were down-regulated in APA group.In the genes related to steroid hormone synthesis,only CYP11B2 was significantly up-regulated.In the physiologic regulators of aldosterone synthesis,CYB5A,CYP17A1,DUSP1 and HMGCR were down-regulated,while RENBP and NR1H2 were up-regulated.As a key enzyme in the biosynthesis of cortisol,the expression of CYP17A1 gene was inhibited. Conclusion Among the aldosterone synthesis related enzyme and corresponding regulatory genes in APA,CYP11B2 may be a key synthetase,and the suppressed physiologic regulators of aldosterone synthesis may indicate the existence of neoplastic modulation.

PURPOSE: To explore the value of transplanting peripheral blood-derived mesenchymal stem cells from allogenic rabbits (rPBMSCs) to treat osteonecrosis of the femoral head (ONFH). MATERIALS AND METHODS: rPBMSCs were separated/cultured from peripheral blood after granulocyte colony-stimulating factor mobilization. Afterwards, mobilized rPBMSCs from a second passage labeled with PKH26 were transplanted into rabbit ONFH models, which were established by liquid nitrogen freezing, to observe the effect of rPBMSCs on ONFH repair. Then, the mRNA expressions of BMP-2 and PPAR-γ in the femoral head were assessed by RT-PCR. RESULTS: After mobilization, the cultured rPBMSCs expressed mesenchymal markers of CD90, CD44, CD29, and CD105, but failed to express CD45, CD14, and CD34. The colony forming efficiency of mobilized rPBMSCs ranged from 2.8 to 10.8 per million peripheral mononuclear cells. After local transplantation, survival of the engrafted cells reached at least 8 weeks. Therein, BMP-2 was up-regulated, while PPAR-γ mRNA was down-regulated. Additionally, bone density and bone trabeculae tended to increase gradually. CONCLUSION: We confirmed that local transplantation of rPBMSCs benefits ONFH treatment and that the beneficial effects are related to the up-regulation of BMP-2 expression and the down-regulation of PPAR-γ expression.

9.Drug-resistance Acinetobacter baumannii infection in burn patients: current situation and countermeasure.
Chinese Journal of Burns 2011;27(2):84-87
Infections caused by Acinetobacter baumannii (AB) have emerged as a knotty clinical problem in the burn wards due to its omni-resistance to antibiotics and high prevalence. Although our knowledge in regard to the pathogenesis and the resistance mechanisms of AB is increasing, the available treatment remains much limited. Measures to effectively control nosocomial infection are warranted. Meanwhile, development of novel therapeutic agents or combination of antibiotics should be considered.

OBJECTIVETo investigate the anatomical bases for electrical coupling of mesenchymal stem cells (MSCs)-derived myocardial cells with host cardiac myocytes.
METHODSMSCs isolated from adult inbred Wistar rats were cultured and expanded in vitro and labeled with gree fluorescence protein (GFP). The model of acute myocardial infarction (AMI) was established in rats of the same species by occlusion of the left anterior descending arteries (LAD). One week after operation, 1.0x10(7) MSCs were injected into the infarcted area and 4 week after transplantation, the cardiac function of the recipient rats was evaluated. The heart tissues were taken after hemodynamic measurement for histological examination and morphometric measurement using image analysis system, and the expression of connexin-43 in the MSCs was detected by immunofluorescent cytochemistry.
RESULTSFour weeks after transplantation, the transplanted MSCs in the infarcted area showed significantly higher expression rate of connexin-43, and the cell transplantation resulted in decreased infarct size and thickening of the left ventricle wall.
CONCLUSIONIn a rat AMI model, MSCs differentiate into myocardial cells which can be integrated into host myocardial cells through formation of gap junction, resulting in effective improvement of the cardiac function.
