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.

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.

Objective To study the clinical effects of the clavicular hook plate in treatment of acromioclavicular joint dislocation. Methods 37 cases with the acromioclavicular joint dislocation surgery were carried out.Results After internal fixation for 6 to 12 months, remove the plate, and then follow up for 3 to 18 months. According to the grading standards in shoulder joint function by Karlsson ,31 cases of A grade,4 cases of B grade,and 2 cases of C grade,the excellent rate is 94.6%. Conclusions Internal fixation with clavicular hook plate is a good method in the treatment of acromioclavicular joint dislocation.

Objective To detect the COMP and aggrecan content in serum of patients with KOA and explore its correlative factors.Methods COMP and aggrecan in serum of 100 patients with knee-osteoarthritis(KOA group)and 30 healthy volunteers (control group)were measured by ELISA.Correlative factors for COMP and aggrecan levels were tested by linear regression analy-sis.Results COMP and aggrecan levels in KOA group were significantly higher than that in control group (P < 0.05 ).Serum COMP and aggrecan levels were positively correlated with age,body mass index(BMI),WOMAC scores and X-ray K-L grade(P <0.05).Conclusion Serum COMP and aggrecan are useful markers in the diagnosis,which their level in KOA are higher than the normal people.Moreover,these rise of levels positively correlated with clinical disease parameters and radiological joint damage.

AIM: To establish the quality standard for Chanhua Junsitifen Capsule(Paecilomyces cicadae(Miquel) samson). METHODS: Amino acids,adenine,adenosine,uridnine in Chanhua Junsitifen Capsule were identified by TLC and adenosine was determined by HPLC.Chromatographic conditions were adopted as follows:co-lumn: Inertsil C_18(4.6 mm?250 mm,5 ?m),mobile phase: MeOH-0.05 mol/L KH_2PO_4 solution(15∶85),wavelength: 260 nm,flow rate: 1.0 mL/min. RESULTS: The average recovery was 99.60 % and RSD was 0.62 % and the linear range of adenosine was in the range 0.007 475-2.99 ?g. CONCLUSION: This method is simple,rapid with a good reproducibility.This method can be used for the quality control of Chanhua Junsitifen Capsule.

Breast cancer is a multistep process with abnormalities of some biomarkers.Knowledge of biomarkers can provide prognostic information in addition to the clinicopathologic factors,and is useful to carry out the indiviual treat- ment.In this review,we summarized the most recent work in the field of biological markers used for the prognosis,such as Her-2/neu,P53,BRCA1,Angiogenesis,LOH,et al

Objective To evaluate the clinical efficacy ofDuhuo Jisheng Decoction in treating liver and kidney deficiency syndrome of knee osteoarthritis (KOA) by ultrasound.Methods A total of 120 cases of KOA patients with liver and kidney deficiency syndrome were randomly divided into two groups (each contains 60 cases). Control group took hydrochloric acid glucosamine capsules, while treatment group tookDuhuo Jisheng Decoction additionally for 8 weeks. ESR, CRP, WOMAC, joint swelling scores, and TCM syndrome scores of the two groups were determined, and the sonographic characteristics of knee-joint effusion in patellar fabricius, synovial membrane, cartilage and bone erosions were compared before and after treatment.Results There were significant differences in ESR, CRP, WOMAC, joint swelling scores, and TCM syndrome scores between before and after treatment in both groups (P<0.05,P<0.01). The knee-joint synovial membrane got thinner after therapy in osteoarthritis patients, and the effusion in knee-joint also decreased. The vessel flow signals in knee-joint synovial membrane of osteoarthritis decreased after drug therapy (P<0.05,P<0.01).ConclusionDuhuo Jisheng Decoction can improve clinical efficacy of KOA with liver and kidney deficiency syndrome. Ultrasound can clearly observe the changes of effusion in patellar fabricius, and synovial membrane, and can provide good imaging assessment for the drug therapy for KOA patients.
