Objective To investigate the effect of endoplasmic reticulum stress (ERS)-associated apoptosis on renal interstitial fibrosis induced by unilateral ureteral obstruction (UUO) in rats. Methods Eighteen healthy male Wistar rats undergoing UUO were sacrificed at 3,7,14 days after operation. Additional seven rats underwent sham operation. Histological changes were observed by HE and Masson staining. Immunohistochemistry was performed on renal tissue for α-smooth muscle actin (α-SMA). Chromatometry was used to detect the content of hydroxyproline. Apoptosis cells were determined by terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) and the electrophoresis analysis of genome DNA. The mRNA expression of glucose-regulated protein 78 (GRP78), which are important markers of ERS, were detected by RT-PCR. Western blotting was used to assess the protein level of GRP78 and cysteinyl aspartate specific proteinase-3 (caspase-3). Results Compared with sham operation group, the degree of renal interstitial and the level of hydroxyproline content of UUO group increased significantly (P<0.05). Immunohistochemistry staining indicated that a-SMA extensively expressed in renal tubular and interstitial cells. The apoptotic cells in the renal tubular and interstitium were continuously increased from day 3 to the end of experiment of UUO group. As early as 3 days after surgery, the mRNA level of GRP78 in UUO group increased compared with sham operation group (P<0.01), while the protein expression increased on day 7 after surgery (P<0.01). Prolonged ERS triggered apoptosis, the protein expression of caspase-3 increased significantly on day 3 after surgery (P< 0.05), and the expression sustained high level during the experiment afterwards. There was a positive correlation between GRP78 protein expression and hydroxyproline content (r =0.657, P< 0.01) as well as caspase-3 protein expression (r=0.714, P<0.01). Conclusions UUO induces a significant up-regulation in endoplasmic reticulum molecular chaperones at early stage, indicating that ERS response is activated in the rat kidney. Prolonged ERS can lead to renal tubular and interstitial cell apoptosis, and caspase-3-mediated ERS associated apoptosis may contribute to the fibrosis.

Pharmacological method state is a method to explain the principle of Chinese herb according to its external phenomenon such as shape, color, texture, features, and so on. The natural attribute of Chinese herb include shape, color, texture, smell, harvesting time, medicinal parts, chemical components, and so on. Though both of them have different key points, the natural attribute of Chinese herb can also be used to explain its medicinal mechanism. Therefore, the correlation research between pharmacological method state and the natural attribute of Chinese herb has some significance.

The factors influencing cost accounting fall into such three categories as drivers and incentives,factors affecting authenticity and accuracy,and factors affecting application and selection.DRG payment,as it is getting more popular than before,is pushing forward cost accounting at an unprecedented pace.Thanks to the current payment system reform and the transition of public hospital reimbursement regime,such needs as exact payment,j ust compensation and cost/performance management of such hospitals are challenging the present cost accounting system,calling for the birth of a cost accounting system for these hospitals.To build such a system,micro-and macro-level goals need to be considered simultaneously,while needs of different levels should be designed,integrated and interacted with each other.Only in this way,goals can be reached for such a system.

Objective To assess the effectiveness of prevention program on iodine deficiency disorders and iodine nutritional status of residents in Guangdong Province.Methods Probability proportionate to size sampling(PPS) was employed in surveillance of iodine deficiency disorders.Thirty counties(cities,districts) were selected in Guangdong Province.In each county(city,district) one township(street) was selected; in each township (street) one primary school was selected and in each primary school 40 children aged 8-10 were chosen to examine their thyroid and to collect salt samples at their home for determination of salt iodine.Out of the 40 children,12 children were chosen to collect urine samples for determination of urinary iodine.From the primary schools chosen,40 grade 5 students were selected for intelligence quotient(IQ) test.In the nearby of the primary schools,3 townships(towns,street) were selected and in each township(town,street) 5 pregnant and 5 lactating women were selected to collect their urine samples for determination of urinary iodine.Type-B ultrasonic was used in measuring the thyroid volume.The iodine content of urine samples was measured by the method of arsenic and cerium catalysis spectrophotometry.The iodine content of salt was determined quantitatively with the titration method.IQ was tested by Chinese combined Raven's test.According to geographical location and the implementation of iodized salt,the effects of iodized salt on iodine deficiency disorders were analyzed in the plains and the Pearl River Delta Coastal region with mild iodine deficiency(iodized salt implementation region,referred to as the plains and the PRD),historical iodine deficiency areas (iodized implementation region) and the eastern and the western coastal areas of Guangdong(areas with non-iodized salt problem,referred to as the eastern and the western Guangdong).Results A total of 1200 children aged 8 to 10 were examined by type-B ultrasonic test,and goiter rate was 3.5％ (42/1200).The differences of goiter rate between the plains and the PRD,the historical iodine deficiency areas and the eastern and the western Guangdong were statistically significant (x2 =6.6,P ＜ 0.05).The goiter rate (6.1％) in the eastern and the western Guangdong was significantly higher than that of the plains and the PRD and the historical iodine deficiency areas (3.3％,2.0％,x2 =5.6,7.1,all P ＜ 0.05).A total of 1200 salt samples were examined.The median and coefficient of variation of iodine in the salt were 31.0 mg/kg and 23.2％,respectively.Coverage of iodized salt was 97.5％(1170/1200) while 96.1％(1153/1200) of consumed iodized salt was qualified.The median urinary iodine of 1200 children aged 8-10 was 186.5 μg/L,and the differences of median urinary iodine between the plains and the PRD,the historical iodine deficiency areas and the eastern and the western Guangdong were statistically significant(x2 =5.9,P ＜ 0.05).The median urinary iodine of the eastern and the western Guangdong(162.4 μg/L) was significantly lower than that of the plains and the PRD(207.5 μg/L,x2 =8.7,P ＜ 0.01).The difference of median urinary iodine between the plains and the PRD,the historical iodine deficiency areas and the eastern and the western Guangdong was statistically significant(x2 =58.9,P＜ 0.01).The median urinary iodine of the eastern and the western Guangdong(109.6 μg/L) was significantly lower than that of the historical iodine deficiency areas and the plains and the PRD(152.9,155.2 μg/L,x2 =18.3,20.6,all P ＜ 0.05).The mean IQ of the 1208 grade 5 students was 102.8 ± 14.3.The IQ of the plains and the PRD(104.3 ± 13.9) and the historical iodine deficiency areas(102.7 ± 14.3) was significantly higher than that of the eastern and the western Guangdong(100.3 ± 14.7,t =3.8,2.1,P＜ 0.01 orP＜ 0.05).Conclusions The goal of iodine deficiency disorders elimination is achieved as scheduled in Guangdong Province.The health level of general population has been improved significantly.Iodine nutrition is in the appropriate range (100-199 μg/L) in general population but low in pregnant women.The selling of non-iodized salt in the eastern and the western Guangdong Province should be followed closely.

An ultra-performance liquid chromatography-quadrupole/time of flight mass spectrometry (UPLC-Q-TOF-MS/MS) combined with reference herb method was developed to rapidly screen commercial sulfur-fumigated ginseng. Sufur-fumigated ginseng reference herb was prepared using genuine ginseng by conventional procedure. Then the reference sulfur-fumigated ginseng sample was analyzed by UPLC-Q-TOF-MS/MS to identify characteristic marker components. 25-hydroxyl-Re sulfate with higher abundance was se- lected as marker compound from 8 characteristic components identified in sulfur-fumigated ginseng reference herb. The fragmentation of 25-hydroxyl-Re sulfate was extensively investigated, fragment ion m/z 879.44 with higher intensity was chosen as the characteristic ion of sulfur-fumigated ginseng. The response of ion m/z 879. 44 was improved by optimizing the MS conditions so that this ion could be used as the characteristic marker ion for screening purpose in ion extracting screening mode. The established approach was successfully applied to inspect 21 commercial ginseng samples collected from different cities in China It was found that the chemical profiles of 9 samples were similar to that of sulfur-fumigated ginseng reference herb, and the characteristic ion m/z 879. 44 of 25-hydroxyl-Re sulfate was also detected in these samples, suggesting that there were nearly 43% ginseng samples analyzed being sulfur-fumigated. This findng agreed well with the results of sulfur dioxide residues of these 21 commercial ginseng samples determined with the method documented in Chinese Pharmacopeia Compared with the method documented in Chinese Pharmacopeia, the proposed approach is more rapid and specific for screening sulfur-fumigated ginseng. SFDA of China should strengthen the enforcement to prohibit ginseng being sulfur-fumigated, so that ginseng and it preparations could be effectively and safely benefit to the health of human beings.

Objective Toinvestigatetheeffectofrehabilitationrobothandontheupperlimbmotor functioninpatientswithstrokeandhemiplegia.Methods Theeffectsoftraditionalrehabilitation therapy or robot rehabilitation treatment of 15 stroke patients with hemiplegia were analyzed retrospectively. There were 4 females and 11 males. According to the group order,they were divided into either a robot rehabilitation group (n=8 )or a general rehabilitation group (n =7 ). The patients of the general rehabilitation group received general rehabilitation training at the Department of Rehabilitation Medicine for 4 weeks,3 times a week,and 30 min for each time. At the same time,they also conducted family rehabilitation training,5 times a week,once for 1 h;the patients of the robot rehabilitation group received the general rehabilitation training for the same length of time as the general rehabilitation group,and they also performed robot rehabilitation training,5 times a week,once for 1 h. The patients of both groups were evaluated with the modified Ashworth scale (MAS )scores,Fugl-Meyer motor assessment of the upper extremity(FMA-UE),andWolfmotorfunctiontest(WMFT)beforeandaftertreatment.Results Compared with before training,the MAS score of the robot rehabilitation group was decreased significantly after four weeks of training. The time in WMFT was shortened significantly and the function score was improved obviously. The scores of upper extremity,hand score,and total FMA score in FMA-UE were improved significantly,and there were significant differences (all P <0. 05 ),while there were no significant differences in various indicators in the general rehabilitation group (all P>0. 05). Comparing the effects after four weeks of rehabilitation in both groups,the robot rehabilitation group was superior to the general rehabilitationgroupforthehandscoreinFMA-UE(allP<0.05).Conclusion Therehabilitation robot hand effectively lowered the upper limb spasticity. It has significant effect for recovery motor function of hand;however,it did not have a significant effect for motor rehabilitation on wrist.

Objective:To investigate the current status and influencing factors of stroke patients.Methods:Using stratified sampling method, 458 stroke patients was investigated for the health behavior from October to December, 2015. Based on PROCEDE-PROCEED model, logistic regression analysis was conducted with the health behavior level of the subjects as the dependent variable, and the characteristic factors in the chi-square test as the independent variables to analyze the factors which influence the health behavior level of stroke patients from predisposing factors, enabling factors and reinforcing factors.Results:The health behavior score of stroke patients was (14.5±3.9), which was at medium level. The score of each dimension was nutrition (0.80±0.25), disease management (0.60±0.26), interpersonal relationship (0.57±0.33), and medication compliance (0.49±0.41). The multiple logistic regression analysis showed that the predisposition factors including age ( OR=2.03, 95% CI=1.08-3.80) and history of hypertension( OR=2.35, 95%=1.16-4.76), the enabling factors including the allocation of social resources ( OR=1.73, 95% CI=0.89-3.36), and the reinforcing factors including family support ( OR=2.03, 95% CI=0.99-4.17) were important factors which affect the health behavior of stroke patients. Conclusion:The health behavior level of stroke patients need to be improved. The relevant community resource allocation system continuously, and focus on the impact of family environment and particularly the elderly and patients with a history of hypertension should be attentioned when improving the health behavior of patients.

Objective To investigate the pathological features of blood vessel inflammation in facioscapulohumeral muscular dystrophy ( FSHD ) and the role of vasculitis on the pathogenesis of FSHD. Methods The clinical manifestations and myopathological features of 26 FSHD patients were retrospectively analyzed and summarized. All of the patients were divided into 2 groups; inflammatory infiltration group and non-inflammatory infiltration group. The latter was further divided into 3 subgroups;endomysial inflammation subgroup, perivasculitis subgroup and transmural vasculitis subgroup.Immunohistochemical staining were carried out in inflammatory infiltration group with anti-CD3, anti-CD4,anti-CD8,anti-CD20 and anti-SMA antibody. The control group was composed of 10 dermatomyositis ( DM)cases and 10 polymyositis ( PM) cases. Results The age of onset was (25. 2 ± 12. 6) years old and the average course was (7. 8 ±7. 3) years. The sex ratio of male to female was 1.6: 1. Five of them had family history. The main clinical features were progressive weakness and atrophy of facial, shoulder girdles and proximal upper limbs muscles. The lower distal limbs and (or) lower distal limbs and pelvic girdle muscles were involved in 18 cases. The main pathological features were shown as followed. Seventeen of them had focal inflammatory cell infiltration, including endomysial inflammation (4/17) , perivasculitis (7/17) , and transmural vasculitis (6/17). Immunohistochemical staining confirmed the major types of inflammatory cells were CD4* T lymphocytes and CD20B lymphocytes, which was familiar with DM. While in PM, CD8+ T lymphocytes were dominant The proportionality of residual muscle fibers obviously decreased in inflammatory infiltration group ( 48. 0% ± 23. 6% ) than non-inflammatory infiltration group ( 94. 3% ±3. 1% , T = 198. 000, P = 0. 000). As to CK levels, there were no significant deviation. Conclusions Obvious inflammatory cell infiltration can be seen in FSHD, the locations of inflammatory cells are endomyosium inflammation, perivasculitis and transmural vasculitis. Transmural vasculitis indicates vascular pathological factor may have something to do with pathogenesis of FSHD.
