Objective To study the effect of SDF1/CXCR4 and FN/?1 integrin modulated by curcumin on the adhesion and migration of B lymphoma Raji cell and to explore the mechanism of curcumin to inhibit the invasiveness of lymphoma.Methods The experiment consisted of eight groups: Control,FN,SDF,FN+anti-?1 integrin,SDF+anti-CXCR4,curcumin+FN,curcumin+SDF.Adhesion assay and migration assay were used to detect the difference of invasiveness among different groups.Results In vitro,SDF1 and FN can increase the adhesion and migration of Raji cells,which can be blocked by ?1 integrin antibody and CXCR4 antibody.Curcumin can inhibit the adhesion and migration of Raji to FN in a dose-dependant manner.Low dosage curcumin had minimal effect on the adhesion and migration of Raji induced by SDF except that 25?mol/L curcumin can inhibit the adhesion and migration of Raji.Conclusion FN/?1 integrin and SDF1/CXCR4 pathway play important roles in the adhesion and migration of Raji cells.Curcumin can decrease the invasiveness of Raji cells through inhibiting FN/?1 integrin.It has good prospect of clinical application.

Culture environment is the key factor in the construction of dermal skin.It was investigated that the effects of the culture methods,including the static culture and spinner flask culture,and stir speeds on the cells proliferation,metabolism and distribution within collagenchitosan sponges.A higher cell density and specific growth rate was obtained with spinner flask culture versus static culture,especially,the 80 r/min spinner flask culture.The cell distribution in dermal substitutes from stirred culture system was more uniform than static culture,as well as that with increase of stir speeds in spinner flask.In summary,the spinner flasks culture with proper stir speed shows promise for the construction of dermal substitutes in vitro.

OBJECTIVE: To investigate the main point of long backbone fracture caused by blunt force in forensic clinical identification and to provide a reference for the inspection and appraisal practices of such injury. METHODS: Ninety-nine cases of adult long backbone fractures were collected from January 2006 to December 2013 in Gutian County of Fujian Province. According to the terms of fracture location, mode of injury, type, the data were summarized. RESULTS: In the 99 cases, there were 36 cases caused by hitting, kicking, and falling and 63 cases caused by vehicle collision. The majority of the former was ulna, and those of the latter were tibia and fibula. The types of fracture were transverse one, short oblique one, long oblique one, and spiral one. CONCLUSION Different types of long backbone fracture, not only causing stress load of fractures as well as structural differences related to each segment.

The leading cause of drug withdrawal from market and clinical trials failure is drug-induced liver injury (DILI). Varying clinical, histological and laboratory features of DILI, as well as undefined underlying mechanisms, hinder patients to be diagnosed in the early-stage of the disease and receive effective treatments. Conventional indicators, like serum transaminases and bilirubin, have inevitable limitations referring to sensitive prediction and specific detection of DILI. In order to reduce the occurrence of DILI, researchers have attempted to discover potential biomarkers with higher specificity and sensitivity from blood and urine in recent years. This article aims to review recent advances in biomarkers of DILI.

Medical emergency response is a part of emergency response to nuclear accident,and the equipment and technology play an important role in the process.So it's important and necessary to research the equipment and technology requirements of medical emergency response to nuclear and radiation accident.The aim of the paper is to screen and list some basic equipments and technology in medical emergency response to nuclear and radiation accident,such as individual internal and external exposure dose monitor,radiation detection appliance,decontamination and radiation protection equipment as well as first-aid instrument.

Objective To compare the safety and effectiveness between treatments with autologous platelet gel (APG) versus standard care for treating refractory diabetic dermal ulcers.Methods The 46 patients with proved nonhealing diabetic dermal ulcers were enrolled. Eligible for the study were patients with grade II/III ulcers according to Wagner, lasting for at least 2 weeks and with no signs of infection at recruitment.Patients were given their informed consent document and randomly assigned to two groups: standard care (ST, n=23) or standard care plus topic application of APG (APG, n=23) for twelve weeks.The treatment of blood glucose, blood pressure and lipids was optimized and the empiric antibiotic treatment was further adjusted according to the results of culture and sensitivity testing in all patients. APG treatment consisted of wound dressing with APG, followed by topical washing and cleaning. The APG was then covered with vaseline gauze for 72 hours, after which the ulcers were treated by standard care. Participants were seen thrice a week, twice a week, or at weekly intervals. Twelve weeks observation was set as the end point.Results The would of APG group were improved in 22 patients with ulcers healed completely and 1 case with would area reduced. In the ST group, 13 ulcers were healed, 6 worsened and 4 with would area reduced. The cumulative rate of ulcer healing was 95.7% in the APG group versus 56.5% in the ST group (P=0.002). The total effective rate in APG vs ST group was 100.0% vs 73.9% (P=0.009). By Kaplan-Meier analysis,the time-to-healing of ulcer and time-to-lutation of sinus were significantly different between two groups (log-rank, P=0.006, 0.000, respectively). No treatment-related adverse events were observed. Conclusions Treatment with APG in addition to standard care results in a significantly faster and better healing for a refractory diabetic dermal ulcer and does not raise any safety concerns. So APG treatment can be a valuable and effective aid in the management of diabetic foot ulcers.

OBJECTIVETo study on the dynamic changes of Codnopsis pilosula for the guidance of the field management.

METHODUsing the random method the influences of the cultivating density and fertilizing weight at four different levels was observed.

RESULT AND CONCLUSIONThe dynamic changes of the biomass, growth period andbiological changes at different growth stages were found out. The most predominant combination of the two factors, the 1.05 million roots/hm2 of the cultivating density and 240 kg x hm(-2) of the fertilizing weight reached the highest accumulation of stems & leaves; 652 mg x d(-1) the 0.6 million roots/hm2 and 240 kg x hm(-2) reached the heaviest single fresh root. The results could be used for the cultivating, fertilizing and practicing SOP of C. pilosula.
