In order to determine the cellular immunestate in patients with multiple myeloma, T-cellsubsets in peripheral blood from 25 cases withmultiple myeloma were measured with SPA-Ig di-rect rosette assay, the activity of interleukin-2 wasinvestigated by using mice thymocyte proliferationassay. The results showed that in multiple myelo-ma, OKT_3~+, OKT_4~+ cell decreased significantly.OKT_6~+ cell increased markedly and the OKT_4/OKT_8 ratio was reduced. The activity of IL-2 in pe-ripheral blood lymphocytes of the patients withmultiple myeloma increased sharply and there wasa significant difference between the active diseaseand the remission disease. The activity of IL-2 inthe remission disease was lower than that in theactive disease but higer than that of the controlgroup. In conclusion, this study indicated thatthere were imbalance of T-cell subsets and abnor-mality of IL-2 production in patients with multiplemyeloma. The data might suggest that there wasdisorder of the cellular immunity in the course ofthe disease.

Autocrine motility factor (AMF) plays an important role in the stimulation of the migration and motility of cells, especially the generation, migration and angiogenesis of tumor. Recently, it has been found that AMF has three isoforms, ATX-t, ATX-m and PD-I alpha. The PD-I alpha isoform is specifically expressed in the brain, which plays extensive functions in nervous system, such as regulating neural development and differentiation, promoting neurotrauma repair, inducing neuropathic pain, even contributing neurodegeneration under some circumstances. This indicates the close relationship of AMF/AMFR and the pathophysiology of the nervous system. This paper mainly reviews the function of AMF and AMFR and its possible mechanism in the nervous system.

Background As a new tonometer,it is necessary to assess the clinical value of Icare rebound tonometer.Objective This study was to compare the intraocular pressure(IOP)values measured by Icare with that measured by GAT,and discuss the clinical value of leare rebound tonometer. Methods IOP measurement was performed on 152 eyes of 78 subjects with suspicious glaucoma,glaucoma,refractive error and normal examinnee by Icare and GAT respectively.The Icare IOP was measured firstly and then the GAT IOP was carried out with the 3-or 5-minute interval.The IOP values were compared between Ieare and GAT.This study was approved by Ethic Committee of Wuhan General Hospital of Chinese PLA.Written informed consent was obtained from each subject prior to this study. Results The mean IOP values of Icare and GAT were(19.16±5.03)mmHg and(18.41±4.52)mmHg respectively.The differences between Icare IOP and CAT IOP were less than or equal to 1 mmHg in 96 of 105 eyes(63.2%).The positive correlation was found between the Icare IOP and GAT IOP(r=0.940,P<0.01).The Ieare IOP was lower than that of GAT when IOPIcare<16 mmHg,however,the IOP of Icare were higher when IOPIcare≥6 mmHg;the IOP of Icare were higher than that of GAT in the total CCT range.The correlation coefficients of IOP of Icare or CAT with CCT were 0.341(P<0.01)and 0.333(P<0.01),respectively. Conclusion Compared with GAT,Icare is more feasible in clinic because it is practicable and reliable.

BACKGROUND: In the treatment of senile distal tibia fractures, locking compression plate (LCP) combined with minimally invasive percutaneous plate osteosynthesis (MIPO) exerts a satisfactory repair effect, and contributes to the function recovery of lower limbs.OBJECTIVE: To retrospectively analyze the efficacy of LCP combined with MIPO versus intramedullary interlocking nailing for senile distal tibia fractures.METHODS: Fifty-six elderly patients with distal tibia fracture were allotted to minimally invasive and intramedullary nailing groups (n=28 per group), and received the treatment of LCP combined with MIPO and intramedullary interlocking nailing fixation, respectively. The operation time, intraoperative blood loss, postoperative AOFAS ankle-hind foot scale scores, postoperative ambulation time, healing time, postoperative complications and the excellent and good rate in Johner-Wruhs' criteria were compared between two groups.RESULTS AND CONCLUSION: (1) The operation time, AOFAS ankle-hind foot scale scores, ambulation time, and healing time in the minimally invasive group were significantly superior to those in the intramedullary nailing group (P < 0.05). (2) The minimally invasive group showed a significantly higher excellent and good rate (96%) than the intramedullary nailing group (79%) (P < 0.05). (3) Compared with the intramedullary nailing group, the incidence of complications was significantly reduced in the minimally invasive group (P < 0.05). (4) Our findings suggest that the combination of LCP and MIPO not only preserves the most of blood supply, and soft tissues surrounding the fracture end as suggested by the BO principle, but also is conducive for fracture healing, and holds good efficacy.

Objective To analyze the association of staphylococcal nuclease domain-containing protein 1(SND1) and T-cell intracellular antigen 1(TIA-1) on stress granules, and the regulation of SND1 on stress granules under stress stimuli. Methods The immunofluorescence assay and laser scanning confocal microscopy were used to observe the co-localization of SND1 protein and TIA-1 protein under stress stimuli, and the over-expression plasmids of pEGFP vector were transfected into HeLa cells and to verify which domain of SND1 co-localized with TIA-1 under stress stimuli. RNA interference-mediated knockdown of the expression of SND1 protein in HeLa cells was measured by Western Blotting assay. Then whether the knockdown of SND1 affected the recruitment of TIA-1 on stress granules was observed. Heat shocks under different times were used to identify whether there were dynamic changes in transportation of SND1 and TIA-1 on stress granules. Results SND1 co-localized with TIA-1 on stress granules under stress stimuli, and the associated domain of SND1 were SN domain. TIA-1 still can be recruited on stress granules but a large amount of stress granules were reduced even though the expression of SND1 protein was decreased. And the transportation of SND1 on stress granules was laged behind TIA-1 under different-times of heat shocks. Conclusion SND1 protein co-localizes with TIA-1 on stress granules, and which co-regulates the cellular stress response under stress stimuli.

Objective To study the risk factors of severe acute pancreatitis(SAP) complicated with MODS at the early stage.Methods One hundred and seven SAP patients served as A group,who admitted from Janurary 1995 to December 1999.One hundred and thirty patients served as B group who admilted from Janurary 2000 to 2005.Age,sex,Ranson' score,APACHEⅡ ,CT score,biliary tract obstruction,hypoxia,lung infection,shock,abdomen compartment syndrome,hyperlipemia,pleural effusion,and mortality were analyzed.Results Twenty-five in the A group and 28 in B group two were complicated with MODS at the early stage.There existed difference in Ranson's score,APACHEⅡ,CT score between patients with and without MODS(P

Objective To investigate effects of magnetic stimulation on apoptosis of nerve cells and the production of inducible nitric oxidate synthase (iNOS) after spinal cord injury (SCI). Methods Thirty-two SpragueDawley male rats were randomly divided into a magnetic stimulation group (n = 16) and a control group (n = 16).SCI models were established by spinal cord transection in both groups. Rats were sacrificed at the 6th, 12th, 24th and 72nd hour post-injury, but the rats in the stimulation group received magnetic stimulation before being sacrificed.Apoptosis index (AI) and iNOS-positive cells rate were recorded at each time point. Results Apoptotic cells could be observed by the 6th hour post-injury, and were elevated from the 24th to the 72th hour. iNOS-positive cells were few at the first two time points, but had increased significantly at the 24th and 72nd hour post-injury. Compared with the control group, the apoptosis index of the stimulation group decreased a little at the 6th and 12th hour, but not significantly. The difference was quite significant at the 24th and 72nd hour, however, and the AI in the stimulation group decreased much more than that in the control group. There was little difference in the rate of iNOS-positive cells between the control and stimulation groups at any time point. Conclusions Magnetic stimulation could inhibit neural apoptosis and protect neurons from secondary SCI, but it has little effect on iNOS production.
