Objective To study the effects of the staging acupuncture combined with physical therapy on the neural function, motor function and activities of daily living in stroke patients. Methods 166 cases were divided into two groups: 83 cases in the treatment group were treated with staging acupuncture combined with physical therapy; 83 cases in the control group were treated with traditional acupuncture combined with physical therapy. They were evaluated with modified Edinburgh-Scandinavia Stroke Scale (MESSS)，Fugl-Meyer Assessment (FMA), and Bathel Index (BI) before and 2 months after treatment. Results There was no significant difference between these 2 groups before treatment (P>0.05), but were significant differences in MESSS, FMA and BI (P<0.05) after treatment. The incidence of recovery after treatment was 90.36% in treatment group, significantly better than that of the control group (74.49%, P<0.05). Conclusion In comparison with the traditional acupuncture, the staging acupuncture can significantly improve the effect on stroke based on the physical therapy.

ObjectiveTo observe the effect of donor liver pretreated by breviscapine on liver transplantation ischemia/reperfusion injury in rats. Methods SD rats served as liver donors and recipients (n =48 each).The recipients were divided into four groups by random number table.The donors in groups A and C were not pretreated with breviscapine,but those in groups B and D were pretreated with 20 mg/L Breviscapine.The cold ischemia time in donor livers of groups A and B was 30-40 min,and that in groups C and D was 12 h. Clotting function, liver function, serum thrombomodulin,caspase3,and relative activity of NF-kB after liver transplantation were assessed,and the pathological changes and TUNEL apoptosis staining were observed.ResultsThe mortality in groups C and D was 40.0％ (8/20) and 29.4％ (5/17),respectively (P＞0.05).There were no significant changes in coagulation function in all groups after operation. The liver function was improved,pathological lesions were alleviated,and apoptosis rate,serum TM,caspase3 expression and activity of NF-kB in the liver tissues of group D were significantly decreased as compared with group C at 3rd day after operation (P＜0.01),but all these parameters in group B had no significant change compared to group A.ConclusionPretreatment of donor livers with breviscapine can reduce the ischemia/reperfusion injury and apoptosis after liver transplantation in rats probably by inhibiting the apoptosis-related pathway and alleviating the damage to the endothelial cells of the liver microcirculation.

Objective To evaluate the role of 131I SPECT/CT in post-surgical re-staging and recurrence risk stratification in patients with DTC and its impact on subsequent treatment strategy.Methods 131I-WBS and 131I SPECT/CT were performed at the same time 5 to 7 d after 131I treatment in 118 patients (33 males,85 females,average age 45 years) with DTC.Difference in the localization and qualitative diagnosis of 131I uptake lesions between 131I-WBS and 131I SPECT/CT were compared.Value of 131I SPECT/CT in the diagnosis of TNM staging,risk stratification and impact on the treatment strategy was evaluated.Paired χ2 test was used for data analysis.Results A total of 509 foci with 131I uptake were detected.131I-WBS found 449 foci with 131I uptake,354 of which (78.84％) were correctly diagnosed.131I SPECT/CT found 509 foci with 131I uptake,and 504(99.02％) were correctly diagnosed.The difference was statistically significant (χ2=21.51,P<0.01).131I-WBS changed the clinical staging in 13 cases with diagnostic accuracy of 5/13.131I SPECT/CT changed the clinical staging in 19 cases and with diagnostic accuracy of 19/19 (χ2=74.41,P<0.01).131I-WBS changed the risk stratification of 13 patients after operation and the accuracy was 5/13,the corresponding data were 22 and 100％(22/22) for 131I SPECT/CT (χ2=74.41,P<0.01).The treatment strategy was changed in 50 patients with 131I SPECT/CT.Conclusions Compared with 131I-WBS,131I SPECT/CT could provide more accurate positioning and qualitative information for 131I treatment and is more accurate in re-staging and risk stratification.

AIM: To induce rat bone marrow mesenchymal stem cells (BMSC) into cardiomyocytes and investigate the influence of serum coming from acute myocardial infarction (AMI) rat on the procedure. METHODS: The passage 3 BMSC were divided into six groups: groupⅠwas control group; groupⅡwas induced with 5-azacytidine; group Ⅲ was induced with 5-azacytidine and serum from AMI rat; group Ⅳ was induced with 5-azacytidine and serum from normal rat; group V and group Ⅵ were induced with serum from AMI rat or normal rat. The cardiac troponin T, GATA-4 and desmin were detected 30 days after induction. RESULTS: After inducing by 5-azacytidine, 5-azacytidine and two kinds of serum, some cells in the three groups differentiated into cardiac like cells. The expressions of cardiac troponin T, GATA-4 and desmin were positive in cells differentiated from BMSC. The troponin T expression in control group and group inducing by AMI serum alone were negative but GATA-4 and desmin expressed weakly. Some cells induced with 5-azacytidine and serum were slowly beating 2 weeks after induction, but the cells induced with 5-azacytidine alone was not beating.CONCLUSION: Serum from AMI can not induce BMSC to differentiate into cardiomyocytes, but it promotes BMSC differentiate into cardiomyocytes induced by 5-azacytidine and facilitate the differentiated cells to mature.

OBJECTIVETo explore the relationship between job burnout and cognitive function and the influencing factors of job burnout among medical staff.

METHODSQuestionnaire survey was conducted for 197 medical workers in a grade-three general hospital in Beijing. Maslach Burnout Inventory-General Survey (MBI-GS) was carried out to assess the degree of job burnout among medical staff; Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) was used to evaluate the overall cognitive function and cognitive situations of different dimensions.

RESULTS(1) There was a certain level of job burnout among medical staff, especially for the emotional exhaustion dimension (13.29 ± 7.67). (2) High level job burnout group (81.08 ± 12.34) scored lower on visual span than low level job burnout group (92.48 ± 19.62), P<0.05. Overall, job burnout had a negative influence on the general cognitive function (P<0.05). (3) The results of regression analysis indicated that, inefficacy was negatively correlated with age (r=-0.162, P<0.05). Job burnout was positively correlated with level of education (r=0.234, P<0.05) as well as exercise frequency (r=0.320, P< 0.001), and emotional exhaustion was correlated with overtime work (r=0.135, P<0.05); Level of job burnout stayed higher among doctors and nurses, compared with administration staff in hospitals (t=2.966, P<0.05).

CONCLUSIONJob burnout of medical staff was relatively in high level; influenced by age, education level, overtime work, exercise frequency and occupational type, job burnout affected the visual span and general cognitive function.

Objective To understand the pathway of iodine intaking among Tibetan, and provide basic data for prevention and control of iodine deficiency disorders (IDD). Methods Through the method of random sampling, the boarding and day student aged 8 - 10 and women of childbearing age were conducted dietary survey to understand the condition of food intaking via the 24 h review method in 2015. Samples of urine, drinking water, dried beef, milk, Qula and fried noodles were collected and tested iodine level. Results Due to taking iodized salt three times a day with meals, the median of urinary iodine among 492 investigated boarding students was 179.2 μg/L;differently, the median of urinary iodine among 298 day students in this investigation was 79.6 μg/L who taking iodized salt only at lunch at school;and in the study, the median of urinary iodine among 158 women of childbearing age who took iodine-free salt daily was 33.7 μg/L. The iodine contents in 51 drinking water samples, 66 dried beef samples, 48 milk samples, 20 Qula samples and 37 fried noodle samples were quantified respectively, and the average iodine contents of each food were 0.8 μg/L in drinking water, 59.1 μg/kg in dried beef, 61.5 μg/kg in milk, 226.4 μg/kg in Qula and 17.0 μg/kg in fried noodles. The acceptable daily intake (ADI) of iodine of the boarding and day students aged from 8 to 10 and women of child bearing age were 234.0, 126.4 and 76.7 μg/d, respectively, among which the ADI of iodine with iodized salt were 208.0, 78.0 and 0.0 μg/d. Conclusion Consuming iodized salt is a main method to get iodine among Tibetans in Nangqian County, so that it is significant to carried out this measure for a long time for free to let them have iodized salt every day instead of iodine-free one.

Objective:To investigate the dietary iodine intake of people in different areas of Qinghai Province, and to provide the basis for scientific iodine supplementation and continuous elimination of iodine deficiency hazards.Methods:From 2018 to 2019, according to administrative division, natural geographical regions, population distribution and economic development level of Qinghai Province, a total of 14 survey sites were selected. One village was selected from each survey site, and 20 households were selected from each village, the salt samples and 24 h urine samples of all family members were collected to detect salt iodine and urinary iodine. One drinking water sample was collected at the five directions of east, west, south, north and middle of each village to detect water iodine. Salt iodine was detected by direct titration, urinary iodine and water iodine were detected by arsenic-cerium catalytic spectrophotometry. At the same time, the 3-day weighing method was used to investigate the diet, the daily dietary iodine intake per capita (the result was expressed as average) and the proportion of dietary iodine in urinary iodine were calculated, the daily dietary iodine intake per capita of different production modes (agricultural region and pastoral region), different geographical environment (Hehuang Valley, Qaidam Basin, Qilian Mountain and Qingnan Plateau), different nationalities (Han, Tibetan, Hui, Mongolian, Tu, Salar) and different economic levels (< 8 000, 8 000 -, 10 000 -, ≥12 000 Yuan) were compared.Results:A total of 999 people from 280 families were surveyed, including 511 males and 488 females. The median water iodine of each survey site was less than 10 μg/L, all of which were environmentally iodine-deficient areas. A total of 280 salt samples were collected, the median salt iodine was 26.0 mg/kg, and the consumption rate of qualified iodized salt was 100% (280/280). A total of 999 urine samples were tested, and the median urinary iodine of people was 192.5 μg/L, which was at an appropriate level of iodine. There was no statistically significant difference ( t =-1.599, P > 0.05) in the daily dietary iodine intake per capita (28.53, 33.44 μg) of people in agricultural region ( n = 643) and pastoral region ( n = 356). The daily dietary iodine intake per capita (25.38, 33.30, 32.98, 34.79 μg) of people in Hehuang Valley ( n = 448), Qaidam Basin ( n = 125), Qilian Mountain ( n = 157), and Qingnan Plateau ( n = 269) were compared, the difference was statistically significant ( F = 2.883, P < 0.05); among them, the daily dietary iodine intake per capita in Hehuang Valley was lower than that in Qingnan Plateau ( P < 0.05). The daily dietary iodine intake per capita of different nationalities were compared, the difference was statistically significant ( F = 3.647, P < 0.05), Salar ( n = 68) and Tibetan ( n = 239) were higher (37.21 and 32.21 μg). The daily dietary iodine intake per capita (38.97, 17.01, 30.86, 33.14 μg) of annual per capita disposable income < 8 000 ( n = 194), 8 000-( n = 221), 10 000-( n = 302), ≥12 000 Yuan ( n = 282) were compared, the difference was statistically significant ( F = 9.407, P < 0.05). The proportions of dietary iodine in urinary iodine of various population ranged from 5.35% to 15.54%. Conclusions:The iodine nutrition of people in Qinghai Province is suitable, the dietary iodine intake of people is closely related to geographical environment, nationality and economic level. But the proportion of dietary iodine in urinary iodine is relatively low, the consumption of iodized salt is still the main way for people to intake iodine, and it is also the main measure to continuously eliminate the harm of iodine deficiency in Qinghai Province.
