Objective: Patient-reported outcome (PRO) method was used to evaluate clinical effects of acupuncture for cervical spondysosis. Methods: With RCT method used, 162 cases were adopted, and 150 cases finished the whole course (treatment group: 76 cases, control group: 74 cases). Treatment group cases were treated by real-acupuncture while control group cases treated by sham-acupuncture. Northwick Park Pain Questionnaire(NPQ)was used as main outcome index, while SF-36 as secondary index. Both groups’ patients were evaluated before and after treatment course, plus one month and 3 months after the end of the treatment course. Results:Treatment group cases got lower NPQ Scores and higher mental health dimensions scores than the control group cases at any evaluation time-point. At the point of one month after the end of the treatment course, the treatment group cases got better social function scores than the control group cases. At the point of three months after the end of the treatment course, the treatment group cases got better body pain and energy scores than the control group cases. Multiple regression analysis showed that three dimensions of SF-36 (social function scores body pain and energy scores) had close relationship with NPQ scores. Conclusion: Acupuncture had satisfactory long-term effect for cervical spondylosis.

Objective: To observe the efficacy of electroacupuncture plus TDP for treating functional dyspepsia Methods: Sixty cases of functional dyspepsia were treated with electroacupuncture plus TDP, and another 60 cases were treated with Domperidone as a control. Results: After 10 treatments, the curative rate in treatment group was 33.3%, with a total effective rate of 91.7%. While in control group, the curative rate was 13.3%, with a total effective rate of 66.7%. There were significant differences between the two groups (P＜0.01,P＜0.001). Conclusion: Electroacupuncture plus TDP had the better therapeutic effect in treating functional dyspepsia.

Objective To develop a selective isolation media which has a high isolation ratio for Legionella.Methods We compared the growth of Legionella pneumonia on BCYE? plate (with DGVP), BCYE?(with GVPC) and BCYE? (with CCCV) by colony count and compared with BCYE? plate. The comparison of isolation ratio of Legionella pneumonia from air-conditions cooling water with 3 kinds of BCYE? plate containing different anti-reagents was performed.Results The results of colony count on BCYE? plate (with DGVP) and BCYE?(with GVPC) was identical with that on BCYE? plate at same concentration. But the result of colony count on BCYE? plate (with CCCV) was half of the former 2 kinds of plate. 5 strains of Legionella pneumonia isolated from 9 central air-condition cooling water were used by BCYE? plate (with DGVP) and BCYE? (with GVPC), while only 2 strains of Legionella pneumonia were isolated by BCYE? plate (with CCCV). Legionella pneumonia wasn′t detected by BCYE? plate.Conclusion BCYE? plate with antibiotics system of CCCV showed obvious suppression to Legionella pneumonia, and so that there was a low isolation ratio to Legionella pneumonia. But BCYE? plate with antibiotics system of DGVP and GVPC had a few suppression and showed a high isolatio ratio for Legionella pneumonia. Moreover, BCYE? plate with antibiotics system of DGVP and GVPC can effectively inhibit non-Legionella and increase isolation ratio of Legionella. They should be the first selection media for Legionella from environment and clinical samples.

Vitamin D deficiency is highly prevalent in the general population including rheumatoid arthritis (RA) patients.Autocrine regulation of vitamin D modulates important immune response.Vitamin D deficiency may be involved in the pathogenesis of many autoimmune diseases including RA.Vitamin D regulates both the innate and adaptive immune responses.Vitamin D's effects on the innate immune system are mainly through the toll-like receptor and on the adaptive immune system through T cell differentiation,particularly the Helper T cell (Th) 17 response.As Thl7 cells are critical in the pathogenesis in RA,what effect will vitamin D deficiency lead to on the RA? Many data have indicated the relationship between vitamin D deficiency and RA disease activities,but not all the results are consistent.Here,we review the immune-modulatory roles of vitamin D and its effects on disease activity,osteoporosis and cardiovascular disease risk in RA.

AIM: To observe the changes of NO, ET-1, SOD and MDA levels in plasma of rats exposed to infrasound. METHODS: Using infrasound (frequency: 8 Hz; sound pressure level:130 dB), the rats were exposed for 1 d, 7 d, 14 d, 21 d and 28 d, 2 h daily, then the levels of NO, ET-1, SOD and MDA were measured after exposure. RESULTS: The changes of NO levels in plasma significantly declined at 7 d and 14 d (P0.05). The changes of ET-1 levels in all groups in plasma were significantly increased (P

0.05).Conclusion The upper limit threshold of fasting U-Ca/Cr ratios in healthy premenopausal women is established,which can provide a reference for the bone metabolism of patients on the high-turnover status.

Objective To prepare 99Tcm-human epidermal growth factor receptor 2 (HER2) affibody (ABH2) and explore its feasibility as an imaging agent in HER2-positive breast cancer.Methods Sodium glucoheptonate and SnCl2 · 2H2O were used to label ABH2 with 99Tcm.The labeling yield and radiochemical purity of 99Tcm-ABH2 were determined.The stability of 99Tcm-ABH2 was tested in PBS and serum.The equilibrium disassociation constant (Kd) of 99Tcm-ABH2 was measured with MBA-MD-361 breast cancer cells.SPECT/CT imaging was carried out at 1.0 h and 4.5 h after injection of 37 MBq 99Tcm-ABH2 in nude mice (n=4) xenografted with MBA-MD-361 breast cancer.The T/NT (liver,brain,lung,heart,bone and muscle) ratios were deduced from SPECT/CT acquired data.For the blocking experiment,200 μg ABH2 was injected intravenously before 99Tcm-ABH2 injection.SPECT/CT imaging was performed in the same way.The T/NT ratios were compared between non-blocked and blocked groups by one-way analysis of variance.Results Fhe labeling yield of 99Tcm-ABH2 was above 99％.99Tcm-ABH2 was substantially stable in PBS and serum;the radiochemical purity was (95.0± 1.0)％ after incubation with serum at 37 ℃ for 6.0 h.The Kd of 99Tcm-ABH2 was 1.7 nmol/L.The radioactive uptake in cancer was visualized at 1.0 h and 4.5 h after injection of 99Tcm-ABH2 in HER2 positive MDA-MB-361 breast cancer.99Tcm-ABH2 was cleared out mainly through urinary system.The ratios of tumor to liver,lung,brain,heart,muscle and bone were 1.81± 0.60,8.95±1.13,20.08±6.12,7.61±0.56,10.62±1.78,11.42±2.07,respectively at 4.5 h after 99Tcm-ABH2 injection.After ABH2 blocking,the corresponding T/NT ratios were 0.60±0.23,3.05± 1.38,5.24±2.17,2.42±1.02,8.16±2.66,2.76±0.48 (F=29.38,P＜0.05) respectively.Conclusion 99Tcm-ABH2 could be synthesized with high purity,and this new agent could be used to image HER2-positive breast cancer specifically.

BACKGROUND:At present, there stil remain controversies concerning the choice of tibial slope in unicompartmental knee arthroplasty, and the related biomechanical studies are rare. OBJECTIVE:To find the rational tibial slope in mobile-bearing unicompartmental knee arthroplasty through the results of finite element analysis. METHODS:A finite element model of normal knee was established and validated using the techniques of three-dimensional reconstruction and finite element pre-processing. Then the finite element models of unicompartmental knee arthroplasty with different tibial slopes were established based on the normal knee model. The finite element analyses were conducted after the boundary conditions and loads were unified. RESULTS AND CONCLUSION: The finite element models of unicompartmental knee arthroplasty with different tibial slopes were established successfuly. The results of the finite element analyses indicated that the posteromedial tibial cortical and cancelous bone stress increased gradualy as the posterior slope increasing, as wel as the load distribution and the cartilage contact pressures of lateral compartment. The anteromedial tibial cortical stress increased significantly with the anterior slope. A posterior tibial slope of 0°-7° can be recommended when implanting a mobile-bearing unicompartmental knee arthroplasty.

Objective To evaluate the clinical diagnostic contribution of 18 F-FDG PET/CT in giant cell arteritis with initial presentation as fever of unknown origin (FUO).Methods Eight cases with initial presentation as FUO diagnosed with the contribution of PET/CT were retrospectively studied in Peking Union Medical College Hospital.The radiologic manifestations of PET/CT were analyzed.Results Eight patients (4 men and 4 women) with average (63 ± 7) years (range from 55-75 years) were included in our study based on the criteria.Non-specific clinical symptoms were common in these patients,including fatigue,night sweat and weight loss.They all suffered from anemia of chronic disease.Not surprisingly,the inflammatory parameters were elevated significantly in all patients.The medical history,physical examination and routine lab and radiologic examinations couldn't reveal the causes of fever.PET/CT was performed in all of them,which demonstrated intense 18F-FDG uptake in the area of aorta and its major branches with maximal standard uptake value (SUVmax) 2.1-4.6 (3.6 ± 0.9).Immunosuppressive agents were effective to control the inflammation activity.The SUV decreased significantly after treatment in the follow-up PET/CT.Conclusions PET/CT has demonstrated high yield of diagnostic contribution in giant cell arteritis with initial presentation as fever of unknown origin.As to elderly FUO patients presenting with prominent inflammatory reaction,PET/CT may provide potential value to differentiate diagnosis from maligancies.
