OBJECTIVETo study the effect of coixenolide on Foxp3+ CD4+ CD25+ regulatory T cells (Treg) in collagen induced arthritis (CIA) mice, and to explore its possible mechanism for treating rheumatiol arthritis.

METHODSFive mice were recruited as a normal control group from 25 mice, and the rest 20 were used in CIA modeling. After successful modeling they were randomly divided in the model control group and the coixenolide group, 10 in each group. Coixenolide injection at 25 mL/kg was intraperitoneally injected to mice in the coixenolide group, while normal saline at 25 mL/kg was intraperitoneally injected to mice in the normal control group and the model control group. The injection lasted for 21 days. Scoring for CIA was performed after injection and arthritis index was calculated. The peripheral blood Foxp3+ CD4+ CD25+ Treg ratio was determined by flow cytometry (FCM).

RESULTSCompared with the normal control group, the arthritis index obviously increased in the model control group (P < 0.01). The arthritis index obviously decreased more in the coixenolide group than in the model control group (P < 0.01). Foxp3+ CD4+ CD25+ Treg levels obviously decreased more in the model control group than in the normal control group (P < 0.01 ). Foxp3+ CD4+ CD25+ Treg levels obviously increased more in the coixenolide control group than in the model control group (P < 0.01).

CONCLUSIONCoixenolide could up-regulate Foxp3+ CD4+ CD25+ Treg ratios in CIA mice, which might play certain immunoregulation roles in the incidence of CIA.

Objective To investigate the stimulative effects of CollagenⅠon the increased adhesion of rabbit bone marrow stromal cells (BMSCs), cytoskeleton actin organization and intracellular free Ca~(2+) concentration. Methods The third generation BMSCs isolated from mature rabbits were cultured at different initial concentrations on cover-slice coated by collagenⅠin RPMI1640 containing 10% fetal calf serum, and cultured on the same kind of cover-slice untreated with collagenⅠas control. The cells adhesive behavior at different times was assessed. Cellular actin organization was described as either typeⅠor typeⅡcells. In general, typeⅠcells are round and represent a preliminary stage of actin assembly, while typeⅡcells are elongated with organized actin fiber network. At the same time intracellular free Ca~(2+) concentration was measured by using calcium fluorescent probe Fluo-3/AM and laser confocal microscope. Results We found more typeⅡcells in BMSCs cultured with collagen typeⅠsix hours after culture than in the control group. At 12 hours 89% of the BMSCs were typeⅡcells, while only 55% were typeⅡcells in the control group. This indicated active cellular actin organization after being modified by collagen typeⅠ. We also found that the BMSCs cultured with collagen typeⅠincreased intracellular free Ca~(2+) concentration in monolayer culture. Conclusions CollagenⅠis effective in promoting the cellular adhesion, which suggests that a kind of internal relationship or cross-talk may exist between cellular actin organization, intracellular free Ca~(2+) concentration and cell adhesion. Further study, however, is needed.

Objective To evaluate the efficacy of siege scheme of TCM for acute cerebral infarction bowel and visceral strike (block pattern). Methods Totally 110 patients were randomly divided into TCM siege scheme group (55 cases) and control group (55 cases) by randomized parallel controlled study with foresight and multicenter. The control group was treated with the standardized treatment, and TCM siege scheme group was treated with TCM siege scheme, including mild hypothermia TCM pillow therapy, TCM rectal enema, and other multiple treatments based on the standardized treatment. The Glasgow Coma Scale (GCS), the time of pulling out urine tube and nasal feeding tube, and the number of tracheotomy caused by illness changes of the two groups were compared. Results The baseline data of two groups have good comparability (P>0.05). On 10, 15 d of treatment, the number of lucid people in the TCM siege scheme group was significantly more than that in the control group (P<0.05). Compared with the control group, treatment group had less number of tracheotomy, and shorter time of success pulling out urine tube and nasogastric feeding tube (P<0.05). Conclusion TCM siege scheme can improve the consciousness of ischemic stroke in patients with acute cerebral infarction bowel and visceral strike, reduce complications, shows shorter successful pull urine tube and nasogastric feeding, and provides guarantee conditions for further rehabilitation treatment.

Objective:To analyze the levels of individual doses to radiation workers receiving medical radiation exposure in hospitals in Jiangxi province, so as to provide reference for radiation protection.Methods:The radiation workers of different types in medical institutions in Jiangxi were investigated from 2014 to 2018, involving diagnostic radiology, radiotherapy, nuclear medicine and interventional radiology. Statistical analyses were made of the individual doses to medical radiation workers in the province.Results:The total number of monitored workers were 23 833 with average annual individual effective dose of 0.316 mSv. NR1 and NR5, the ratios of the number of workers receiving annual individual doses exceeding 1 and 5 mSv to the total monitored workers were 4.32% and 0.10%, respectively. During the five-year period, the average annual individual effective dose showed a upward and then downward trend, with peak appearing in 2017. A total of 17 909 diagnostic radiologists were monitored, accounting for 75.14% of the total number of monitored workers. The average annual individual effective dose received by workers was 0.329 mSv, the highest, in interventional radiology, followed by diagnostic radiology 0.318 mSv, nuclear medicine 0.283 mSv, and radiotherapy 0.269 mSv, respectively. There were statistically significant differences among radiation workers of different types ( χ2=489.39, P<0.001). Conclusions:The average annual individual effective dose to the radiation workers in medical institutions in Jiangxi province meets the relevant national standards, but with an upward trend in nuclear medicine. The higher levels of individual doses to radiation workers are seen in primary and secondary hospitals. It should be strengthen the oversight of radiation workers in nuclear medicine and in primary and secondary hospitals.

Objective To evaluate the effects of sevoflurane on the development of posttraumatic stress disorder (PTSD) in rats and the role of hippocampal glycogen synthase kinase-3beta (GSK-3β).Methods Forty male Sprague-Dawley rats,weighing 250-300 g,aged 2 months,were randomly divided into 4 groups (n =10 each):control group (group C) ; PTSD group (group P) ; sevoflurane group (group S) ; lithium chloride (LiC1) + sevoflurane group (group LS).Establishment of PTSD model:the rats received 15 footshocks (1 mA,1 s shocks with a variable intershock interval of 240-480 s) in room A on the first day.On the second day,the rats received 1 footshock after an adaptation of 192 s in room B where its context was completely different from room A,and then they were removed from room B 32 s later.The rats were placed in room B and observed for 512 s on the third day.Group C did not receive any treatment on the first day in room A,while the other three groups received 15 footshocks in room A.In addition,0.8％ sevoflurane was administrated while training in group S,and group LS received intraperitoneal LiCl 100 mg/kg at 30 min before entering room A,and then the other treatments were similar to those previously described in group S.The ratio of freezing was recorded in room B on the second and third days.Four rats in each group were randomly sacrificed at 2 h after training in room A on the first day and their hippocampal tissues were taken to detect the expression of GSK-3β and phosphorylated GSK-3β (p-GSK-3β).Results Compared with group C,the ratio of freezing was significantly increased on the third day and the p-GSK-3β expression was up-regulated in P and LS groups,and no significant change was found in the parameters mentioned above in group S.Compared with group P,the ratio of freezing was significantly decreased on the third day and the p-GSK-3β expression was down-regulated in group S,and no significant change was found in the parameters mentioned above in group LS.Compared with group S,the ratio of freezing was significantly increased on the third day and the p-GSK-3β expression was up-regulated in group LS.There was no significant difference in the ratio of freezing on the second day and expression of p-GSK-3β between the four groups.Conclusion Sevoflurane can inhibit the development of PTSD in rats,and enhancement of hippocampal GSK-3β activity may be involved in the mechanism.
