OBJECTIVETo explore the analgesic effect of Zhixin Formula (ZF) and its effects on spinal glial fibrillary acidic protein (glial fibillary acidic protein, GFAP, a marker of astrocyte) , CD11b (a maker of microglia), Toll like receptors (TLR2 and TLR4) and nuclear factor κB (NF-κB) in bone cancer pain model rats.

METHODSTotally 20 male SD rats were randomly divided into the blank control group and the bone cancer pain group, 10 in each group. The bone cancer pain model was induced by injecting ascites tumor fluid containing 3 x 10(3) Walker256 cell line from the left tibia. Ethological tests, X-ray test, and HE staining were performed to confirm a successful modeling. After model was successfully established, 70 male SD rats were randomly divided into seven groups, 10 in each group: the blank control group, the bone cancer pain group (as the model group), the Western medicine (WM) group (Tramadol Hydrochloride), the high dose ZF group, the middle dose ZF group, the low dose ZF group, and the Chinese medicine (CM) group (Wulin Zhitong Capsule). Fourteen days after modeling, rats in the high, middle, and low dose ZF groups were administrated by gastrogavage with 9, 4.5, and 2.25 g/kg ZF water condensed preparation respectively, once a day for seven consecutive days. On day 21 MS typical protein expressions including GFAP, CD11b, TLR (2,4) and NF-κB from cornu dorsal medullae spindis L4-L5 were detected by immunohistochemistry, reverse transcription-polymerase chain reaction (RT-PCR) and Western blot.

RESULTSCompare with the blank control group, increased weight in the model group was slow and showed a decreasing trend (P < 0.01), spontaneous ambulatory pain score (SAPS) obviously increased (P < 0.01), paw withdrawal threshold (PWT) obviously decreased in the model group (P < 0.05, P < 0.01). Results of lateral tibial X-ray and HE staining showed obvious changes and damage occurred in bone structures of rats in the model group. Immunohistochemistry showed that GFAP expression significantly increased in the model group (P < 0.05). Protein levels of NF-κB also significantly increased in the model group (P < 0.05). Compared with the model group, CD11b expressions obviously decreased in the middle and high dose ZF groups (P < 0.01). Meanwhile, protein expressions of TLR2 and TLR4, as well as NF-κB also obviously decreased (P < 0.05).

CONCLUSIONZF had analgesic effect, which might be probably related to inhibiting proliferation and activation of gliocytes, as well as activation of TLRs and NF-κB.

Objective To study the role of glucagon-like peptide-1 (GLP-1) analogue liraglutide played in the proliferation of CD4+CD25 T cells in normal people and newly-onset type 1 diabetic patients,and to evaluate the possible immune regulatory role of liraglutide in the therapy of type 1 diabetes.Methods CD4+ CD25-T cells of 10 normal people and 10 newly-onset type 1 diabetic patients were separated from peripheral blood by MACS immunomagnetic beads and stimulated by Human T-Activator CD3/CD28 Dynabeads to proliferate.CFSE labeling technique was used to evaluate the proliferation of CD4+ CD25-T cells by flow cytometry.Liraglutide of different concentrations(0,25,50,and 100 nmol/ml) was added to the proliferation system,then the proliferation of CD4+CD25-T cell was measured.Results (1) Liraglutide suppressed the proliferation of CD4+ CD25-T cells from either normal people or type 1 diahetic patients with dose-dependent manner (P ＜ 0.05).(2) Under the different concentrationsofliraglutide,the proliferation ofCD4+CD25 T cells from diabetic patients was mueh more robust than that of normal people (P＜0.01).(3) The inhibitory effects of liraglutide on CD4+ CD25-T cells proliferation in normal people and diabetic patients were similar (P＞0.05).Conclusion The proliferation of CD4+ CD25 T cells in type 1 diabetic patients was more robust than normal people,which indicated cellular immune dysfunction in type 1diabetes.Liraglutide inhibits the proliferation of CD4+ CD25-T cells of type 1 diabetic patients in vitro.The immunosuppression effect of liraglutide may have potential value in the treatment of type 1 diabetes.

Objective To provide evidence for the clinical prevention and treatment of prostate cancer by the clinical study in elderly patients with prostate cancer and metabolic syndrome(MS).Methods 196 patients diagnosed as prostate cancer in our hospital from July 2007 to March 2013 were recruited.Clinical data,including age,height,body weight,waistline,triacylglycerol(TG),high density lipoprotein cholesterol (HDL-C),fasting blood glucose (FPG),prostate specific antigen (PSA),prostate volume(PV),systolic and diastolic blood pressures and pathological Gleason score,were analyzed.Patients were divided into two groups of prostate cancer with and without MS.Results The prostate cancer with MS group showed no statistical differences from simple prostate cancer group in the levels of age,TG,systolic pressure(SBP),diastolic pressure(DBP) and Gleason score(all P＞0.05),but had statistical differences in the levels of BMI,waistline,FPG,HDL-C,PSAandPV(t=2.89,2.67,3.13,-3.16,-3.13,3.14,respectively,all P＜0.05).SerumPSA level was lower in patients with obesity and high level of TG than in patients without obesity and high level of TG(t=4.27 and 3.89,all P＜0.01),while serum PSA level was lower in men with high FPG and low HDL than in men with normal levels of FPG and HDL-C,but had no statistically significant differences(all P＞0.05).Serum PSA level was higher in patients with high diastolic pressure than with normal diastolic pressure level(t=0.138,P＜0.01).PSA was positively correlated with age and DBP(r=0.21 and 0.18,both P＜0.01) and negatively correlated with BMI,FPG,TG(r=-0.12,-0.18,-0.03,respectively,all P＜0.01),but had no significant correlations with waistline,HDLC,and SBP.Conclusions The correlation of the occurrence and development of prostate cancer with metabolic syndrome may exist,and the level of serum PSA is also correlated with MS.Serum PSA level is affected by age,DBP,BMI,FPG and TG.

Objective To investigate the utility of bedside electromyography (EMG) in diagnosis and management of critical illness patients with suspected neuromuscular diseases.Methods Bedside EMG was performed in 34 critical illness patients with weakness and respiratory involvement,including segmental motor nerve conduction studies,sensory nerve conduction studies,F waves,concentric needle EMG and repetitive nerve stimulation.The clinical manifestations and clinical utility of bedside EMG in critical illness patients with suspected neuromuscular diseases were analyzed. Results EMG was normal in 5 patients.Low-frequency repetitive nerve stimulation showed decrement response of compound muscle action potential (CMAP) in 4 of 8 patients.Motor nerve conduction studies showed CMAP amplitude decreased in 73.3％(22/30) patients,and demyelinating changes was detected in 20.0％ (6/30)patients.F-wave persistence was 0 in 55.0％ (11/20) patients.Amplitude of sensory nerve action potential decreased in 28.6％ (6/21)patients.Bedside EMG could help to confirm or exclude diagnoses and guide the management in 82.4％(28/34) patients,confirm the diagnoses of peripheral neuropathy but have no effect on management in 11.8％ (4/34) patients,and bedside EMG was inconclusive in 2 patients.Conclusions Bedside EMG is useful for the diagnosis and management of critical ill with suspected neuromuscular diseases,while motor nerve conduction studies and repetitive nerve stimulation are more valuable.Individualized protocol for EMG studies should be made on the basis of clinical problem.

OBJECTIVE: To evaluate the quality of reports published in recent 10 years in China about quantitative analysis of syndrome differentiation for diabetes mellitus (DM) in order to explore the methodological problems in these reports and find possible solutions. METHODS: The main medical literature databases in China were searched. Thirty-one articles were included and evaluated by the principles of clinical epidemiology. RESULTS: There were many mistakes and deficiencies in these articles, such as clinical trial designs, diagnosis criteria for DM, standards of syndrome differentiation of DM, case inclusive and exclusive criteria, sample size and estimation, data comparability and statistical methods. CONCLUSION: It is necessary and important to improve the quality of reports concerning quantitative analysis of syndrome differentiation of DM in light of the principles of clinical epidemiology.
