Objective To examine the epidemiology of kidney stone in Pudong New Area ofShanghai and analyze its risk factors. Methods 12 565 residents with the age above 16 years weresurveyed. All subjects needed to answer a questionnaire concerning their sex,age,geographic loca tions,occupation,education status and family history of renal calculi,etc. Ultrasound examinationwas used to diagnose the kidney stone. Results The average prevalence of kidney stone was 3.15%(396/12565),4. 05%(247/6096)in the men and 2.30%(149/6469) in the women,respectively (P<0. 05). The prevalence increased significantly with age of men,whereas the prevalence was highest forwomen aged 50-59. The prevalence between city and rural was not significantly different before age60 (2.58% vs 2. 62%,P>0. 05),whereas the prevalence were significantly different after age 60(6.28% vs 3.36%,P<0.05). The prevalence of subjects with a family history of renal calculi washigher than that without family history (32.02% vs 2.06%,P<0. 01). The prevalence in manage ment staff and vehicle drivers were the highest. Conclusions The prevalence of kidney stone in Pud ong New Area of Shanghai was lower than that in south of China. The relative risk increased in sub jects of aged men,women aged 50 59,with family history of renal calculi,management staff and ve hicle drivers. An understanding of the epidemiology particularly the interactions among different fac tors,may help lead to approach that reduce the risk of stone formation.

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 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 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.

ObjectiveTo investigate the clinical characteristics in ABO-incompatible allogeneic peripheral blood stem cell transplantation(allo-PBSCT).Methods137 patients'clinical courses who accepted allo-PBSCT were retrospectively reviewed. Sixty-five cases of them were ABO-incompatible allo-PBSCT patients,including 32 ABO major mismatched cases,23 ABO minor mismatched cases and 10 ABO major and minor mismatched cases.Seventy-two ABO-identical cases were taken as control group.ResultsCompared with ABO-idential cases,the time of erythrocyte recovery after allo-PBSCT in ABO major and minor mismatched group was delayed [(73.2+10.3) d vs (97.5+10.4) d] (P <0.05).In ABO-incompatible group, the time of blood type switching in different ABO-incompatible types were found no significant difference (P >0.05) [ABO major mismatched:(45.7±17.3) d,ABO minor mismatched:(41.2+16.1) d and ABO major and minor mismatched:(48.4±20.9) d (P > 0.05)].There were 8 cases who have a delayed time of blood type changing, including 6 cases demonstrated recipient-derived anti-A antibody. ConclusionABO-incompatible has no negative effect on allo-PBSCT.The time of erythrocyte reconstitution was delayed in ABO major and minor mismatched group.A delayed time of blood type switching tends to occur in ABO minor incompatible cases and patients who have anti-A antibody initially.
