Objective To explore the characteristics of DNA antigen deposited in the skin lesions of patients with lupus erythematosus (LE). Methods Thirty-two LE skin specimens were collected. The deposited immune complexes were obtained by cryoprecipitation methods. Then the samples were digested by protease. Finally DNA was extracted with phenol and chloroform. The size of DNA fragments was detected on agarose gel electrophoresis. Ten kinds of probes were used to analyze the origin of these DNA molecules by dot hybridization. Results DNA fragments were successfully isolated from 27 skin specimens with four kinds of different sizes including band-I (20 000 bp), band-Ⅱ (1 300 bp), band-Ⅲ (800-900 bp) and band-Ⅳ (100-120 bp). In 15 specimens most of DNA was identified as band-I. In 2 specimens band-Ⅰ, -Ⅱ and -Ⅲ were all noticed, while all four bands were detected in 10 specimens. There was a positive correlation between small-sized fragments (100-200 bp) and disease activity (P

Objective To investigate whether endogenous retinal stem cells can be activated in the retina of Royal College of Surgeons (RCS) rats during the onset and development of retinitis pigmentosa. Methods The RCS-p+ rats with inherited retinal dystrophy were divided into 3 groups: the initial stage group (15-day RCS rats), the mid-stage group (30-day RCS rats) and the advanced stage group (90-day RCS rats) according to the severity of degeneration (n=4 in each group). RCS-rdy+p+ rats without retinal degeneration served as controls, and divide into three groups (15-day control, 30-day control, 90-day control) matched with RCS-p+ rats. A transcription factor (Chx10) expressed by embryonic retinal progenitors was detected using immunofluorescence and Western blotting. Results All of the retinal layers in the three control groups and in the 15-day RCS rats did not express Chx10, while the positive expression was observed in the photoreceptor layers of the 30-day and 90-day RCS rats. Chx10 protein could be detected by Western blotting in all RCS groups, but expressed higher in 30-day RCS rats than in 15-day and 90-day RCS rats (P

Objective To investigate the role of microglial activation in spinal cord in a rat model of persistent postoperative pain evoked by skin/muscle incision and retraction (SMIR) .Methods Seventy-two male SD rats weighing 200-250 g in which intrathecal (IT) catheter was successfully inserted were randomly divided into 3 groups ( n = 24 each) : group sham operation; group SMIR and group SMIR + FT minocycline (a specific microglia inhibitor) . The rat model of persistent postoperative pain evoked by SMIR was established according to the method described by Flatters. Pain behavior was assessed by paw mechanical withdrawal threshold ( MWT) to von Frey filament stimulation at 1 day before (T0,baseline) and 3, 7, 12, 22 and 32 days after operation (T1-5,) . Four animals were sacrificed at each time point in each group for detection of the expression of Iba-1 (a specific marker of microglia) in the spinal dorsal horn by immunofluorescence and the microglia was counted. Results MWT was significantly decreasedat T1-4, while the expression of Iba-1 and microglia counts in the spinal dorsal horn were significantly increased at T1, 2 by SMIR in group Ⅱ. IT minocycline significantly attenuated the hyperalgesia induced by SMIR at T1-4 and decreased Iba-1 expression and microglia counts at T1,2 in group Ⅲ. Conclusion Microglial activation in the spinal cord plays an important role in the development and maintenance of SMIR-evoked persistent postoperative pain in rats.

Objective To study the inhibition activity of volatile oil from Mappianthus iodoies on SPC-A-1 and BEL-7402 cancer cells.Methods The volatile oil in Mappianthus iodoie was extracted by SFE-CO2.MTT assay was employed to test the antitumor effect of volatile oil from Mappianthus iodoies in two kinds of malignant tumor cell lines,with IC50 applied to evaluate the degree of inhibition activity.Results When the dose of volatile oil from Mappianthus iodoies was 200 μg/ml,the inhibition ratios of the tumor cell was in excess of 50％,the IC50 was 169.54,695.21 μg/ml respectively.Conclusion Volatile oil from Mappianthus iodoies extracted by SFE-CO2 has obvious inhibition activity on SPC-A-1 and BEL-7402 cancer cells.

ObjectiveTo investigate the role of NF-κB signaling pathway in the spinal cord in persistent postoperative pain evoked by skin/muscle incision and retraction (SMIR) in rats.MethodsNinety male SD rats weighing 200-250 g in which intrathecal (IT) catheter was successfully implanted without complication were randomly divided into 3 groups ( n =30 each):group sham operation ( group S ) ; groups SMIR and group pyrrolidine dithiocarbarnate (a NF-κB inhibitor) (group PDTC).Persistent postoperative pain was evoked by SMIR according to the method described by Flatters in groups SMIR and PDTC.PDTC 10 ng in 10 μl was injected IT over 30 s once a day for 7 consecutive days after operation in group PDTC.Mechanical paw withdrawal threshold to von Frey filament stimulation (MWT) was measured at 1 d before (T0,baseline) and 1,3,7,12 and 22 d after surgery (T1-5).Five animals in each group were sacrificed at each time point after MWT measurement and their lumbar segments of the spinal cord were removed for determination of TNF-α content (by ELISA).ResultsSMIR significantly decreased MWT after operation at T1-5 and increased TNF-α content in the spinal cord at T3-5.PDTC significantly attenuated SMIR-induced hyperalgesia and increase in TNF-α content in the spinal cord.Conclusion NF-κB signaling pathway in the spinal cord plays an important role in the development of SMIR-induced persistent postoperafive pain in rats.

Analysis of domestic and overseas literature on the relationship between Alzheimer disease (AD) and neural stem cells (NSC) shows that inducing the proliferation and differentiation of hippocampal endogenous NSC in-situ by acupuncture is probably the mechanism of acupuncture therapy in treating AD, and that it may further improve the method for the research on AD.

This article reported the results of eight series of animal experiments. In each series, the rats were divided into two groups: the experimental group was fed on corns and vegetables from endemic districts; the control group, from non-endemic districts. The composition of the foodstuffs was the same in the two groups. 375 albino rats were used in the experimental group, and 315 rats in the control group. The observation period was 8-13 weeks.The results showed that the incidence of myocardionecrosis had increased, the heart weight was comparatively larger, the mortality rate was higher, growth was stunted and the weights of the thymus and brown fat were lower than those of controls. The differences between experimental and control groups were stastistically singnificant. Such difference was not due to the composition of foodstuffs, but was closely related to the districts, from where the corns and vegetables were obtained. The results of these eight series of experiments were similar, and with very good reproducibility. It seemed that there were some myocardiac necroti-zing and growth inhibition factors in the corns and vegetables from the Keshan disease endemic districts.
