[Objective]To analyze the therapeutic effects of percutaneous kyphoplasty for acute versus chronic osteoporotic vertebral compressive fracture.[Method]Percutaneous kyphoplasty was performed in 56 patients(137 vertebraes) with osteoporotic vertebral compression fracture (VCF).Based on the changes on MRI,all compression fractures were divided into 3 types:acute VCF,repairing VCF and chronic VCF.Types were examined for differences in treatment efficacy,according to the anterior/middle vertebral body height,Cobb's angle and visual analogue scale(VAS) at pre-and post-operation.[Result]All patients with the VCFs had rapid and significant improvement in back pain following percutaneous kyphoplasty.VAS was from 8.09?1.12 preoperatively to 2.31?0.91 postoperatively,and 2.26?0.88 at final follow-up.The results showed that 41 cases were Type Ⅰ on MRI,69 were Type Ⅱ and 27 were Type Ⅲ.Significant improvement was observed at the post-operative versus pre-operative assessments in Type Ⅰ and Type Ⅱ.No significant differences were observed between post-and pre-operative assessments in Type Ⅲ.[Conclusion]The curative effect of percutaneous kyphoplasty for the treatment of acute VCFs appears superior to that of chronic VCFs.After a definite diagnosis of VCFs,percutaneous kyphoplasty should be performed as early as possible in order to obtain a better therapeutic effect.

[Objective]To observe the correlation between electromyogram(EMG) combined with MRI and clinical outcome in patients with cervical spondylotic myelopathy(CSM). [Methods]Patients with CSM who were confirmed by clinical and image examination were examined by EMG.Peripheral nerve injury such as cubital tunnel syndrome and carp tunnelsyndrome were excluded.Eighty-nine cases were selected and followed-up after surgical treatment with anterior,posterior,or posterior-anterior combined surgery.Four types were classified according to EMG and MRI.Type I:EMG/MRI(-/-).Type II:EMG/MRI(-/+).Type III: EMG/MRI(+/-).Type IV:EMG/MRI(+/+).The clinical outcome were also graded according to the Japanese Orthopaedic Association(JOA) scoring system.Furthermore,the data were analyzed statistically to explore the correlation of the factors.[Results]The results showed that 36 cases were in Type Ⅰ,17 were in Type Ⅱ,10 were in Type Ⅲ and 26 were in Type Ⅳ.Clinical function was excellent in 42 patients,good in 20 patients,fair in 18 patients,and poor in 9 patients.There was a good correlation between types and the clinical outcome(Hc=30.72,P

Oxidation and free radicals participate in the pathological process of multiple diseases in organisms, and acupuncture shows good effect in antagonizing oxygen stress (OS). This article reviews the effect of acupuncture in antagonizing oxygen stress and the mechanism of its anti-free radical effect in various diseases. The authors hold that acupuncture not only has a chain-blocking effect, but also has preventive and repairing effects of anti-oxidation. And anti-OS action is one of the important mechanisms of acupuncture.

OBJECTIVE To investigate the distribution and bacterial resistance of nosocomial infection.METHODS The data of 45 hospitals from Shandong Provincial Nosocomial Surveillance System from Jan 2003 to Dec 2005 were analyzed.RESULTS Of total 5 626 isolates strains from the nosocomial infection cases,G-bacilli,G+ cocci and fungi accounted for 58.27%,25.84% and 15.89%,respectively.The ampicillin-resistant rate of commonly encountered G-bacilli was above 89%.There were 72.98% of E.coli resistant to ciprofloxacin.The rates of resistance of S.aureus and coagulase negative Staphylococcus to penicillin,ampicillin and erythromycin were all above 80%;the lincomycin-resistant rate of S.aureus increased gradually to 86.64%.CONCLUSIONS Drug resistance of the nosocomial infective bacteria is a serous problem.Surveillance of bacterial resistance should be strengthened.

Aim To investigate the effects of anti-in-flammation and antioxidation of an amphiphilic curcu-min derivative (Curc-OEG)on CCl4-induced hepatic fibrosis in rats.Methods Rats were randomly divided into four groups:control group,model group,curcumin and Curc-OEG treatment group.All rats except those in control group were given subcuta-neous injection of CCl4 and olive oil mixture,twice a week for 8 weeks.After 4 weeks,rats of control and model group were trea-ted with normal saline intravenously,curcumin group were ad-ministered with curcumin 400 mg.kg -1 .d -1 by gavage and Curc-OEG group were treated with Curc-OEG 1 00 mg.kg -1 .d -1 intra-venously respectively.After 4 weeks treatment,the serum levels of ALT and AST were tested.HE and Sirus staining were used to evaluate the extent of liver inflammation and fibrosis.The mRNA expression levels of proinflammatory cytokines of NF-kB,IL-1 β, IL-6,TNF-α,COX-2 were observed with Real Time PCR.The level of MOD,SOD and GSH in liver of rats were quantified. Results The levels of ALT in control,model,curcumin and Curc-OEG group was (31 .7 ±8.7)U·L -1 ,(383.0 ±75.6) U·L -1 ,(406.3 ±204.7)U·L -1 ,(1 07.0 ±73.7)U·L -1 respectively;that of AST was (1 37.7 ±32.7)U·L -1 ,(585.3 ±36.7)U·L -1 ,(485.0 ±246.5)U·L -1 ,(202.7 ±56.0) U·L -1 respectively,Curc-OEG possessed more hepatoprotective effects than that of curcumin.Liver pathology showed Curc-OEG treatment could significantly alleviate steatosis,reduce inflamma-tion and apparently suppress hepatic fibrogenesis by reducing the thickness of bridging fibrotic septa.Compared with curcumin, Curc-OEG down-regulated mRNA and protein expression levels of NF-kB,IL-1 β,IL-6,TNF-α,COX-2 (P <0.05 ).Moreo-ver,Curc-OEG reduced the level of MOD and increased the lev-els of SOD and GSH.Conclusion Curc-OEG could more sig-nificantly protect the rat liver from CCl4-caused fibrogenesis by anti-inflammatory and antioxidant effect than curcumin.

OBJECTIVETo evaluate the changes in programmed death 1 (PD-1) and programmed death ligand 1 (PD-L1) expression on peripheral blood T lymphocytes of patients with chronic hepatitis C (CHC) over the 24 weeks course of antiviral therapy.

METHODSTwenty-four CHC patients administered 24 weeks of combination antiviral therapy with pegylated-interferon-alpha-2a (Peg-IFNa-2a) and ribavirin (RBV) were enrolled for study from the Nanjing Second Hospital between October 2008 and October 2011. Peripheral blood was collected before treatment initiation, at treatment weeks 4, 12 and 24, and post-treatment week 24 (to investigate sustained virologic response (SVR), and used to measure expression of PD-1 and PD-L1 on CD4+ and CD8+ T lymphocytes by flow cytometry, load of serum hepatitis C virus (HCV) RNA by real-time polymerase chain reaction, and level of serum alanine aminotransferase (ALT) by auto-biochemical analyzer. Intergroup differences were analyzed by the two-sample t-test, and the significance of differences between pre- and post-treatment measurements was determined by one-way or two-way repeated measurements analysis of variance tests.

RESULTSAt treatment week 4, 19 of the CHC patients were HCV RNA-negative. Among those patients the PD-1 expression on both T lymphocyte subsets showed a significant decrease from pre-treatment to post-treatment week 24 (CD4+: 18.6 +/- 6.1% vs. 10.3 +/- 7.7%, F = 12.406, P = 0.002; CD8+: 16.6 +/- 13.8% vs. 9.4 +/- 4.6%, F = 4.955, P = 0.039). However, the CD8+ lymphocyte subset showed significant increase in PD-L1 expression during treatment (pre-treatment: 17.5 +/- 13.7% vs. treatment week 4: 25.9 +/- 11.1%, F = 9.063, P less than 0.01; 12: 29.6 +/- 15.1%, F = 8.365, P less than 0.01; 24: 32.0 +/- 15.7%, F = 9.736, P less than 0.01). Among the five CHC patients showing HCV RNA-positivity at treatment week 4 there was only a significant difference observed in the increased expression of PD-L1 on CD8+ lymphocyte subset from pre-treatment to treatment week 24 (17.4 +/- 16.7% vs. 39.2 +/- 15.6%, F = 10.292, P = 0.033). Twenty of the CHC patients achieved SVR. among whom the PD-1 expression was significantly decreased during treatment on the CD4+ lymphocyte subset (pre-treatment: 20.2 +/- 7.5% vs. treatment week 4: 14.4 +/- 7.5%, F = 6.133, P less than 0.05; 12: 14.0 +/- 6.9%, F = 5.541, P less than 0.05; 24: 10.7 +/- 7.6%, F = 14.780, P less than 0.05) and on the CD8+ lymphocyte subset (pre-treatment: 16.8 +/- 13.4% vs. treatment week 12: 10.2 +/- 4.6%, F = 4.964, P less than 0.05; 24: 10.1 +/- 4.9%, F = 4.613, P less than 0.05). Additionally, the PD-L1 expression was significantly increased during treatment on the CD8+ lymphocyte subset (pre-treatment: 19.0 +/- 14.5% vs. treatment week 12: 30.8 +/- 16.6%, F = 6.442, P = 0.020; 24: 35.2 +/- 16.5%, F = 12.349, P = 0.002). Among the four CHC patients who relapsed there were no significant differences observed in the expressions of PD-1 or PD-L1 on the CD4+ or CD8+ T lymphocytes.

CONCLUSIONThe standard Peg-IFNa-2a + RBV combination antiviral therapy reduces PD-1 expression on CD4+ and CD8+ T lymphocytes and increases PD-L1 expression on CD8+ T lymphocytes in peripheral blood. The clinical outcome of CHC patients may be related to the antiviral therapy-induced changes in expressions of PD-1 and PD-L1 on T lymphocytes.

OBJECTIVETo investigate the effect of c-kit mutation on the prognosis of gastrointestinal stromal tumors.

METHODSA search of studies in PubMed and MedLine (from 1999 to 2008) was performed to assess the effect of c-kit mutation on the prognosis of gastrointestinal stromal tumors. The articles were retrieved with the entries of "gastrointestinal stromal tumors", "imatinib", "c-kit" and "mutation". A meta-analysis was performed to assess the data included.

RESULTSA total of 15 articles were collected in this analysis. No significant differences was found in incidence of mitoses (> 5/50 HPF) between the patients with wild type c-kit (wild type group) and the ones with mutated c-kit (mutation group) (P = 0.710); tumor recurrence and metastasis rate after surgery was significant higher in the mutation group than that in wild type group (P = 0.010); as for imatinib response with different c-kit mutation types, the results showed the incidence of clinical response (complete response + partial response) was significantly higher in mutation group than that in wild type group (P = 0.009), but the imatinib resistance rate was lower in mutation group (P = 0.000); three studies provided data for imatinib resistance with c-kit second mutations, the results showed the second mutations mainly focus on exon 13, 14, 17.

CONCLUSIONSC-kit mutation is related closely with the incidence of recurrence and metastasis in GIST after surgery. The mutations of c-kit influences the therapeutic effects of imatinib.

This paper is aimed to provide the methods of quality control and bioassay of traditional Chinese medicine injections including bioassay method. Shuanghuanglian freeze-dried powder for injection (SFPI) was chosen as study object. HPLC-ELSD fingerprints of SFPI had been established and the samples were differentiated by similarity calculation. Meanwhile, biological profiles of SFPI on Escherichia coli had been established by microcalorimetry. The similarity values were calculated using the correlation coefficient, based on quantitative thermo-kinetic parameters (T2m, Tj, I%). The results indicated that HPLC-ELSD fingerprints, which showed content changes of chemical components, could not monitor minimal variation of different samples, especially that of biological pollutants, while biological profiles could sensitively detect antibiotic activity alterations of the samples, which were kept under specific conditions. In conclusion, characterized by two-dimension, microcalorimetry could supply thermograms as biological profiles characterized to describe the bioactivity of drugs. This study could clearly demonstrate that the correlative detection was proposed as an efficient strategy for quality control of SFPI, based on HPLC-ELSD fingerprints and biological profiles, which could detect quality fluctuation of samples early and quickly and predict the potential adverse drug events (ADE) for ensuring clinical safety.
