Exercise is one of the important techniques of cardiovascular rehabilitation. Exercise can reduce inflammatory response to improve endothelial function, and improve mitochondrial function to increase myocardial cell activity. For cardiovascular risk factors, exer-cise can promote the activity of lipoprotein, increase the level of high-density lipoprotein;improve the function of insulin receptor to reduce insulin resistance, reduce platelet aggregation and improve endothelial function to reduce blood pressure. For the respiratory system, aerobic exercise can improve the function of respiratory muscle, thus relieve the dyspnea. Exercise can promote the activation of immune factor and increase metabolism, to increase immune function and anti-aging. Resistance exercise can improve mitochondrial function and promote fi-ber type conversion, to improve the function of skeletal muscle system.

Lymph node metastasis is a main route of metastasis for rectal cancer,and skip metastasis is an im portant characteristic.Many cases were found metastasis or micrometastasis in lateral or upper lymph node before the definite metastasis in mesenterium lymph node.To exactly check and diagnose the lymphnode metastasis can help manage CLIN,and influence the prognosis.In reeent years,progress has achieved in the study of lymphnode micrometestasis,and it is really a promotion for the management of rectal cancer.

Objective To improve the quality standard of Qixue Shuangbu Oral Liquid;To provide guarantee for the quality of oral liquids.Methods HPLC was used to simultaneously determine the contents of paeoniflorin and icariin in the oral liquid. The determination was performed on a Agiltnt TC-C18 (2) column (250 mm × 4.6 mm, 5μm) with the mobile phase of acetonitrile and 0.1% H3PO4 gradient mode. The flow rate was 1.0 mL/min;the column temperature was set at 25℃; the detection wavelength was 232 nm.Results The linear ranges of paeoniflorin and icariin were obtained between 0.542-8.677μg (r=0.999 9) and 0.185-2.963μg (r=0.999 9), with the average recoveries (n=6) of 99.29% (RSD=1.06%) and 98.91% (RSD=1.97%), respectively.Conclusion This method is accurate and feasible, which can be used conveniently in quality control ofQixue Shuangbu Oral Liquid.

Objective:To improve the quality standard of Tongsai Yinao oral liquids for the quality control. Methods: TLC was used for the qualitative identification of Rhizoma corydails, Rhizoma chuanxiong and Rhizoma acori tatarinowii. HPLC was used to sim-ultaneously determine the content of total ferulic acid in the oral liquids. The determination was performed on a Lichrospher-C18 (250 mm×4.6 mm,5 μm)column with the mobile phase of methanol-0.1% H3PO4(30∶70). The flow rate was 1.0 ml·min-1,the col-umn temperature was at 30℃, the detection wavelength was 321nm and the injection volume was 20μl. Results:The spots on the TLC plates were clear without the interference of negative control. The linear range of ferulic acid was obtained between 2. 24 and 35. 84 μg ·ml-1(r=0. 999 9), and the average recovery was 102. 54%(RSD=0. 85%, n=6). Conclusion:The improved method is accu-rate and feasible. It can be used very conveniently in the quality control.

BACKGROUND:Compared with bone marrow and autologous peripheral blood stem cells, umbilical cord mesenchymal stem cells are characterized as more primitive, more powerful amplification and lower immunogenicity, no ethical problems, which are more important to the elderly patients with diabetes mel itus. OBJECTIVE:To evaluate the efficacy and safety of umbilical cord mesenchymal stem cells transplantation in the treatment of the elderly patients with diabetic lower limb vascular disease. METHODS:Fifty-six elderly patients with diabetic lower limb vascular disease were randomly divided into observation group and control group. The control group was treated with conventional therapy, while the observation group was treated with umbilical cord mesenchymal stem cells transplantation. RESULTS AND CONCLUSION:Observation group showed a higher efficiency than the control group, with significant difference (P<0.05). After treatment, foot skin temperature, transcutaneous oxygen pressure, and ankle brachial index were al improved in both two groups, and the ankle brachial index showed a better value in the observation group (P<0.05). There were no significant adverse reactions in the two groups. Umbilical cord mesenchymal stem cells transplantation is a simple, safe and effective therapy for the elderly patients with diabetic lower limb vascular disease, with better short-term curative effect.

UiO-66 (University of Oslo 66) is a kind of promising material that can improve the release and bioavailability of poorly water-soluble bioactive compounds of traditional Chinese medicine. However, the loading of quercetin in raw UiO-66 was not ideal. In this study, UiO-66-BH (UiO-66-blend-heating) was obtained by heating UiO-66 and KOH solution following blended them. UiO-66-BH maintained the outline of octahedral structure of UiO-66 but with obvious rough and uneven pores on the surface. UiO-66-BH had good adsorption of quercetin with saturation adsorption was 138.92 mg·g^-1, the adsorption process belonged to single molecular layer adsorption and was controlled by chemisorption. UiO-66-BH can control the release of quercetin in simulated gastrointestinal fluid, and the drug concentration was significantly higher than that of free quercetin after long-term release (36% vs 9%). Compared with quercetin, the ABTS (2,2′-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) ammonium salt) radical scavenging activity of UiO-66-BH@quercetin drug delivery system decreased, while the DPPH (1,1-diphenyl-2-picrylhydrazyl) radical scavenging activity remained almost unchanged. The drug delivery system showed a strong antioxidant effect similar to quercetin. The findings indicated that UiO-66-BH could control release of quercetin and was expected to be used as a drug carrier material for some insoluble active components of traditional Chinese medicine such as quercetin.

With continuous discovery of tumor immune targets and continuous changes in antibody research and development technology, antibody drugs are becoming more and more widely used in clinical practice. However, some targets are not only expressed on tumor cells, but also on red blood cells. Therefore, the clinical application of antibodies against the corresponding targets may interfere with the detection of blood transfusion compatibility, resulting in difficulty in blood matching or delay of blood transfusion. This consensus summarizes the current solutions for the interference of CD38 monoclonal antibody (CD38 mAb) in transfusion compatibility testing. After analyzing the advantages and disadvantages of different methods, polybrene and sulfhydryl reducing agents [dithiothreitol (DTT) or 2-mercaptoethanol (2-Me)], as a solution for CD38 mAb interference in blood compatibility testing, are recommended for Chinese patients, so as to eliminate blood transfusion interference produce by CD38 mAb and further provide a pre-transfusion workflow for clinicians and technicians in Department of Blood Transfusion.
