Objective: To observe the clinical efficacy of DZWJY-1 type electronic moxibustion apparatus and traditional moxibustion in treating knee osteoarthritis (KOA). Methods: A total of 76 eligible patients were randomized into an electronic moxibustion apparatus group and a traditional moxibustion group, with 38 cases in each group. The electronic moxibustion apparatus group was intervened by DZWJY-1 type electronic moxibustion apparatus, and the traditional moxibustion group received moxa stick moxibustion for treatment. Neixiyan (EX-LE 4), Dubi (ST 35), Xuehai (SP 10) and Liangqiu (ST 34) were selected for both groups and the treatment was conducted 3 times a week for a total of 12 times. The visual analog scale (VAS) and the Western Ontario and McMaster Universities osteoarthritis index (WOMAC) scores were observed before treatment and after 6 and 12 sessions of treatment, respectively. Results: There were 4 dropout cases in the traditional moxibustion group. Therefore, this trial had 72 valid cases, including 38 cases in the electronic moxibustion apparatus group and 34 cases in the traditional moxibustion group, the differences in the baseline data between the two groups were statistically insignificant (P>0.05). After 6 and 12 sessions of treatment, the VAS scores decreased significantly with the increase of treatment sessions in both groups (all P<0.01), and the betweengroup differences were statistically insignificant at the same time points (both P>0.05). The pain intensity was evaluated using the weighted value of VAS score. The markedly effective rate was 47.4％ and the total effective rate was 89.5％ in the electronic moxibustion apparatus group, versus 50.0％ and 94.1％ in the traditional moxibustion group, and the betweengroup differences were statistically insignificant (both P>0.05). After 6 and 12 sessions of treatment, the total score and the component scores including pain, stiffness and difficulty moving in the WOMAC decreased significantly with the increase of treatment sessions in both groups (all P<0.01), and the between-group differences were statistically insignificant (all P>0.05). Conclusion: Electronic moxibustion apparatus and traditional moxibustion both are effective in reducing joint pain and improving joint function in KOA patients, and they are equivalent comparing the clinical efficacy.

Objective To investigate the expression of peroxisome proliferator-activated receptor (PPAR?)in lupus nephritis(LN)patients and the possible mechanisms of PPAR?in the pathogenesis of LN. Method PPAR?expression was examined in 21 LN patients and 5 normal kidney biopsy specimens by im- munohistochemical method.The relationship between PPAR?expression and renal pathologic changes was an- alyzed.Results Glomerular and tubular positive staining of PPAR?in LN patients was markedly up-regulated compared with that in normal kidney specimens.The distribution and expression of PPAR?in classⅣwas sig- nificantly increased compared with that in classⅤandⅡ.The relevance assay showed that there was positive relationship between active index and glomerular PPAR?immunohistochemistry staining cell numbers(r=0.94, P＜0.01 ).Conclusion This study demonstrates in vivo that PPAR?expression is increased in active LN pa- tients with pathological active inflammation.These data suggest that the increase of PPAR?expression in renal cells may play an important role in the pathogenesis of LN.

[Objective]To investigate the efficacy and cost analysis ofmicrosurgical clipping and vascular embolization in the treatment of patients with cerebral aneurysms.[Methods]Two hundred and fitly-one patients with cerebral ameurysms,admitted to our hospital from January 2007 to December 2010,were collected in our study;170 patients (174 aneurysms) received microsurgical surgical clipping (clipping group) and other 181 patients (185 aneurysms) were performed vascular embolization (embolization group).Duration of hospitalization,vascular occlusion rate,intraoperative rupture rate,hospital mortality and happening of complications were compared between the 2 groups;and the efficacy were evaluated by modified Rankin scale (mRS) and cost analysis of the 2 treatments were compared 3 months after the surgeries.[Results] The length of hospital stays and cerebral aneurysm rupture rate in patients of the embolization group were significantly shorter/lower than those in the clipping group (P＜ 0.05);the scores of mRS showed no significant differences between the 2 groups (P＞0.05).The cost and sensitivity analysis indicated that the ratio of average cost/good prognosis rate in the clipping group was smaller as compared with that in the embolization group.[Conclusion] The efficacies of microsurgical clipping and embolization in the treatment of cerebral aneurysms are considerable,and both of them have their advantages and disadvantages respectively;however,the microsurgical clipping is cost-effective and economical.

AIMTo analyze the chemical components in Danggui (the roots of Angelica sinensis (Oliv.) Diel).

METHODSHPLC-MS/MS was used to identify the main components in Danggui. Furthermore, the MS fragmentation regularity of the phthalides was proposed. The mobile phase of HPLC consisted of 0.5% acetic acid in water and 0.5% acetic acid in acetonitrile, analytical column was Hypersil ODS2 (250 mm x 4.6 mm, 5 microm), flow rate 1.0 mL x min(-1), injected volume 2 microL. The ionization source was ESI in positive ion mode.

RESULTSFerulic acid, nine known phthalides and one unknown phthalide derivative were tentatively identified in chromatograms based on their MS data and the comparison of their UV spectra with those published in the literatures.

CONCLUSIONThe structural information of phthalides was obtained via HPLC-MS/MS, which provides an accurate and fast method to identify the phthalides and provides more scientific information for quality control of Danggui.

OBJECTIVEThe aim of this study is to compare the clinicopathologic characteristics and disease-free survival of triple-negative breast cancer with human epidermal growth factor receptor-2-overexpressing (Her-2-overexpressing) breast cancer.

METHODS770 breast cancer patients were surgically treated between 1998 and 2003 in Changhai Hospital, Shanghai. Patients with triple negative phenotype were identified from those using immunochemistry and CISH. The differences between triple-negative breast cancer and Her-2-overexpressing breast cancers were analyzed in p53 and E-cadherin status, age, tumor size, tumor location, histological types and grading, lymph node metastasis, AJCC stage, chemotherapy and surgical procedures,as well as identified prognostic factors with regards to disease-free survival.

RESULTSNinety-six (12.5%) patients with triple-negative phenotype, and 164 (21.3%) with Her-2-overexpressing one were identified from the 770 breast cancer patients. No significant difference between two phenotypes in p53 and E-cadherin expression was found (P>0.05). When compared with Her-2-overexpressing breast cancer patients, triple negative breast cancer patients experienced more lymph node metastases (71.9% vs. 58.5%, P = 0.034), and had a higher percentage of more than 10 lymph nodes metastases (26.0% vs. 12.2%, P = 0.034); and showed a higher percentage of histological grade 3 (67.7% vs. 42.1%, P<0.0001). Furthermore, the tumor size was found to be related to lymph node metastasis in triple-negative breast cancer patients (P = 0.024). No significant difference between the two phenotypes in the rates of local recurrence and distant metastasis was observed (P>0.05). However, 5-year disease-free survival in patients with triple negative phenotype was significantly shorter than that in the patients with Her-2-overexpressing phenotype (61.85 mon vs. 78.69 mon, P = 0.047).

CONCLUSIONCompared with Her-2-overexpressing breast cancer, triple-negative breast cancer is more malignant and has a poorer disease-free survival.

To construct plasmid of recombinant protein candidate vaccine of respiratory syncytial virus, express it in E. coli, and to investigate its immunogenicity and protective efficacy. A CD8+ T cell epitope from respiratory syncytial virus (RSV) M2 protein F/M2:81 - 95 and the G:125-225 (G1) gene fragments from RSV-G protein containing B cell epitopes were amplified by PCR method and then inserted into the prokaryotic expression vector pET-DsbA after bonding to a linker. The fusion protein DsbA-G1-Linker-F/M2:81-95 (D-G1LF/M2) was expressed successfully in E. coli BL21 (DE3). The product was proved to be RSV-specific by Western-blot. After purified by affinity chromatography on Ni+ Sepharose and renatured by gradient dialysis. D-G1LF/M2 was used to immune BALB/c mice. D-G1LF/M2 induced high anti-D-G1LF/M2 IgG, anti-RSV IgG and neutralizing antibody titers in serum and lung of BALB/c mice, and elicied RSV-specific CTL responses. The IgG subclass distribution revealed that IgG1/IgG2a ratio was 2.66. Viral titration indicated that D-G1LF/M2 could protect BALB/c mice against RSV challenge in lung.
