BACKGROUND:Autologous conditioned serum (ACS) is a new and safe biological therapy method mainly used for osteoarthritis, rheumatoid arthritis and other similar diseases. OBJECTIVE:To explore the purification method and cytokine profile of ACS. METHODS:Blood obtained equipment (containing 3 mm of glass beads) was used to collect peripheral blood samples that were mixed uniformly and then placed in a 37℃ thermostatic incubator for 24 hours, finally filtered to obtain ACS. The quantitative determination of interleukin (IL)-1Ra, IL-6, IL-8, and IL-1β was conducted, and the 36 kinds of cytokines were semi-quantitatively detected by cytokine antibody array. RESULTS AND CONCLUSION: The levels of various cytokines in ACS were obviously increased, among which, IL-1Ra level (important for alleviating osteoarthritis) was increased from 140.25 ng/L to 1125 ng/L(increased by above 8 times); IL-6 level was increased from 389.5 ng/L to 2802 ng/L; IL-8 level was not detected firstly and finally increased to 2822 ng/L. Cytokine antibody array results showed that at least 10 kinds of cytokines in ACS were changed, and most of cytokines were on a rise, and few in decline. These results indicate that the ACS contains IL-1Ra and a variety of cytokines, and some chemokines in the ACS recruit more immune cells to the inflammation sites and accelerate the inflammatory process, further exerting therapeutic effects.

OBJECTIVE: To observe the clinical effects of Xinfeng Capsules (XFC), a traditional Chinese medicine for invigorating the spleen to resolve dampness and dredging collaterals, on patients with rheumatoid arthritis (RA) and anemia, and to investigate its mechanism. METHODS: Forty patients with RA and anemia were divided into three groups: XFC-treated group (n=20), Tripterygium glycosides Tablets (TGT)-treated group (n=10) and methotrexate (MTX)-treated group (n=10). The patients in each group took corresponding medicine for three months. The response rates of the three groups were evaluated after treatment. The general symptoms and specific signs and symptoms of RA were observed before and after the treatment. The indexes of blood routine examination and some other laboratory indexes such as erythrocyte sedimentation rate (ESR), and blood levels of rheumatoid factor (RF), iron, C-reaction protein (CRP), immunoglobins (Ig), complements 3 and 4, tumor necrosis factor-alpha (TNF-alpha), interleukin-10 (IL-10) and erythropoietin (EPO) were all examined and compared before and after treatment. RESULTS: The total response rate in the XFC-treated group was similar to those both in the TGT-treated and MTX-treated groups. The effects on relieving specific symptoms of RA in the three groups were also similar. The ESR and serum levels of RF, CRP, IgG, IgA and IgM were all decreased after treatment as compared with those before treatment in the three groups, and there were no significant differences among those laboratory indexes in the three groups after treatment. The XFC displayed more obvious effects on improving the general symptoms of patients with RA and anemia, increasing the blood levels of hemoglobin, iron and IL-10, while decreasing the serum level of TNF-alpha and regulating the serum EPO level, as compared with those in the TGT-treated and MTX-treated groups. CONCLUSION: The XFC for invigorating the spleen to resolve dampness and dredging collaterals was developed on the basic principle of regulating spleen. It can obviously improve the symptoms and laboratory indicators of RA. Such effects may be related to maintaining the balance of cytokines, regulating the serum level of EPO and increasing the serum iron level in patients with RA and anemia.

Application of image processing technology reduced the noise and sundry of output images. Conclusion The accuracy of three dimensional facial measurement system based on structured light projection is high. The image output is reliable, and can be clinically used in facial scanning and three dimensional reconstruction.

Objective To investigate the expression and early diagnosis value of CD64 index levels in peripheral blood cells in patients with postoperative traumatic sepsis.Methods A number of 420 trauma patients were enrolled in the study,and they were divided into the postoperative traumatic sepsis group(130 cases)and postoperative general trauma group(290 cases)according to the clinical manifestations. The CD64 levels in peripheral blood were measured by flow cytometry,and the levels of C-reactive protein(CRP)and white blood cell count (WBC)were detected.The diagnostic value of these indexes on postoperative traumatic sepsis were evaluated.Results The CD64 index, CRP and WBC levels in postoperative traumatic sepsis group were significantly higher than postoperative general trauma group(P <0.05). After appropriate treatment,the CD64 index,CRP and WBC levels decreased significantly compared with the preoperative levels(P <0.05). The correlation analysis showed that the CD64 index in peripheral blood and CRP level were positively correlated(r =0.79,P <0.01).How-ever,the CD64 index in peripheral blood and WBC level were of no significant correlation(r =0.028,P >0.05).The ROC curve analysis showed that when CD64 index(7.21)considered as the boundary for early diagnosis of postoperative traumatic sepsis,the sensitivity and spe-cificity of diagnosis for postoperative traumatic sepsis were 85.1% and 87.8%,the area under the ROC curve(AUC)was 0.865(95%CI 0.784 ~0.929),which was significantly better than CRP index.Conclusion The expression of CD64 is higher in patients with postoperative traumatic sepsis,which can be used as an effective indicator for early diagnosis of postoperative traumatic sepsis,and it has an important clin-ical application value.

Objective: To observe the clinical efficacy of acupuncture plus subtle adjustment manipulation of the cervical spine for peripheral facial paralysis.Methods: A total of 60 patients with peripheral facial paralysis who met the screening criteria were selected and divided into two groups according to the method of random number table, with 30 cases in each group. The patients in the acupuncture plus tuina group received routine treatment of acupuncture and subtle adjustment manipulation of the cervical spine, while the patients in the acupuncture group only received the same acupuncture treatment. Assessment of peripheral facial paralysis with integrated traditional Chinese and Western medicine was adopted for rehabilitation assessment. Results: The total effective rate of the acupuncture plus tuina group was 93.3％, while that of the acupuncture group was 70.0％, and there was a significant between-group difference (P<0.05). After treatment, the total scores of rehabilitation assessment in both groups were significantly higher than those before treatment (both P<0.05), and the score of the acupuncture plus tuina group was significantly higher than that of the acupuncture group (P<0.05). Conclusion: The treatment of acupuncture plus subtle adjustment manipulation of the cervical spine can improve the function of facial muscles in patients with peripheral facial paralysis, and its clinical efficacy is better than that of the acupuncture treatment alone.

With the continuous development of bone tissue engineering, a variety of emerging bone graft materials provided various methods for repairing bone defects. Early and rapid accomplishment of revascularization of materials interior after implantation of bone transplantation materials is a difficulty faced to bone tissue engineering. Blood vessels ingrowth provides the requisite netritional support for the regeneration reconstruction of bone tissue, for this reason, vascularization plays a significant role in bone tissue engineering. However,there is not a golden standard strategy of vascularization at present. Scaffold materials, cells and growth factors still are three indispensable elements in tissue engineering, and are cardinal points of the promoting vascularization strategies. Multiple growth factors or multiple cells combined with scaffolds, which are hot spots, have obtained excellent vascularization. This review focused on the comprehensive strategies for promoting the successful vascularization of tissue engineered scaffolds.

The aim of this study is to prepare hyaluronic acid (HA) modified core-shell liponanoparticles (pHA-LCS-NPs) as gene delivery system and investigate its gene transfection efficiency in human retinal pigment epithelium (ARPE-19) cells in vitro. The pHA-LCS-NPs was prepared by firstly hydrating dry lipid film with CS-NPs suspension to get LCS-NPs, then modifying the lipid bilayer with HA by amidation reaction between HA and dioleoyl phosphatidylethanolamine (DOPE). Its morphology, particle size and zeta potential were investigated. XTT assay was used to evaluate the cell safety of different vectors in vitro. The gene transfection efficiency of pHA-LCS-NPs modified with different contents of HA was investigated in ARPE-19 cells with green fluorescent protein (pEGFP) as the reporter gene. The results showed that the obtained pHA-LCS-NPs exhibited a clear core-shell structure with the average particles size of (214.9 +/- 7.2) nm and zeta potential of (-35 +/- 3.7) mV. The 24 h cumulative release of gene from pHA-LCS-NPs was less than 30%. After 48 h incubation, gene transfection efficiency of pHA-LCS-NPs/pEGFP was 1.81 times and 3.75 times higher than that of CS-NPs/pEGFP and naked pEGFP, respectively. Also no obvious cytotoxicity was observed on pHA-LCS-NPs. It suggested that the pHA-LCS-NPs might be promising non-viral gene delivery systems with high efficiency and low cytotoxicity.
