Purpose To study the clinicopathological features of the phosphaturic mesenchymal tumors. Methods The clinicopatho-logical data, histology and immunohistochemical findings of 12 cases of phosphaturic mesenchymal tumors were retrospectively analyzed with review of the relevant literature. Results Among the 12 patients studied, 8 were males and 4 were females. Their age at the time of operation ranged from 23 to 63 years (mean=40. 5 years). The duration of symptoms ranged from 1 to 14 years (mean =5. 6 years) . A history of long-standing bone pain, arthralgia, limitation in movement, accompanied with hypophosphatemia and hyperphos-phaturia were present in all cases. The tumors size ranged from 1 to 7. 5 cm ( mean size=2. 7 cm) . The tumors were primarily com-posed of spindle cells, and were accompanied with osteoclast-like giant cells partly. Their background were rich in blood vessels. In addition, there were scattered tufed thick vascular anomaly, thin vascular, islands of mature adipocytes and chondroid cells. In 7 of the 12 cases, there were dystrophic calcification in an unusual flocculent. Spindle epithelium were noted in 2 cases. Mitotic figures were rare in 10 cases. In 2 of the 12 cases however, mitotic figures were commonly encountered, and in 1 of the 2 cases, heterotypic cells were notablely observed as well. On immunohistochemical study, the tumor cells were all positive for vimentin and CD56. The positivi-ty for NSE, CD99, BCL-2 in 11, 8 and 7 cases were expressed in 12 cases. In 4 and 6 of the 12 cases, CD34 and SMA were positive in various degree. Ki-67 proliferation index were less than 5% in 10 cases, and 10% and 25% in 2 cases. The duration of follow-up ranged from 2 to 108 months ( mean=22 months) . 2 cases were recurred at 72 and 84 months after the operation, respectively. So far, the remaining 10 cases had no recurrence and metastasis. Conclusioin The phosphaturic mesenchymal tumors are either benign or low-grade malignant. Their histomorphology are multivariable and short of specificity. It is important to make the correct diagnosis in combination with their common features and clinical datas.

Evidence-based medicine is advocated by WHO and adopted by developed countries for many years. In China, however, the selection of essential medicine and various medical insurance reimbursement schemes medicine is usually based on experts' experience of prescription practice which is under heavy critics resulting from the lack of related comparative efficacy and evidence-based research. The efficacy of Jian'ganle in prevention of drug-induced liver injury (DILI) caused by antituberculotics was evaluated in this study by comparison with Hugan Pian, glucuronolactone and reduced glutathione. Evidence was provided for relevant sectors such as Ministry for Human Resources and Social Security of the People's Republic of China and National Health and Family Planning Commission of the People's Republic of China to select and renew the Essential Medicine List (EML), the new rural cooperative medical scheme in China (NRCMS) list or the reimbursement list of industrial injury insurance. A total of 189 patients with initial pulmonary tuberculosis were divided into four groups who took antituberculotics combined with Jian'ganle, Hugan Pian, glucuronolactone and reduced glutathione respectively. Their liver function profile including alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBIL), direct bilirubin (DBIL), total protein (TP), albumin (A) and globulin (G) were detected at admission as baseline and after treatment. The Jian'ganle group was compared with the three others by chi-square tests. In an aspect of maintaining bilirubin indexes normal, Jian'ganle was more efficacious than glucuronolactone. And Jian'ganle had a little more efficacy than reduced glutathione to maintain protein indexes normal as well. And the therapeutic regimen of antituberculotics combined with Jian'ganle was the best in treating tuberculosis and preventing DILI at the same time. The study showed that among the four hepatinicas which demonstrated similar prevention of DILI caused by antituberculotics, Jian'ganle has more advantages over the three others to some extent, which provides a reliable basis for health sectors to select and renew the EML, NRCMS List or the reimbursement list of industrial injury insurance.

Objective: To understand the effects of remuneration incentive and their influences on job satis-faction in county public hospital. Methods: Stratified random sampling was adopted. Six county public hospitals in county level in Heilongjiang province were selected as the sample. Exploratory factor analysis was used to ana-lyze the remuneration incentives, descriptive statistical analysis and logistic regression analysis were used to ana-lyze the effects and their influences on work satisfaction. Results: remuneration incentives are divided into four dimensions that comprised a total of 16 items, which including direct material rewards, indirect material re-wards, occupational rewards and social rewards. The surgeon’s job satisfaction is higher than the physician, and is lower than the obstetrics and gynecology and pediatrics. Technician and nurses’ satisfaction is lower than the general practitioner. The medical staff who worked less than5 years has the lowest satisfaction. Authorized staff’s satisfaction is lower than off-staff. Direct material rewards and occupational rewards are related to job satisfac-tion. Conclusions:Material rewards were in low level, and non-economic incentive was insufficient. The salary incentive for highly educated talents should be strengthened.

This study is to investigate the inhibitory effect of lidamycin (LDM) and its combination with methotrexate (MTX) on lung metastasis of fibrosarcoma by bioluminescence imaging in athymic mice. A stable luciferase transfected HT-1080 cell line was constructed and the capability to establish experimental lung metastasis in athymic mice was confirmed. The optical imaging system was applied to evaluate the formation of lung metastasis in vivo. In addition, metastatic nodules were counted for the evaluation of inhibition rates. As shown, the fluorescent intensity of luciferase-transfected HT-1080 cells was colinear with the cell population and the minimal detected cell population was 100 cells/well. Optical imaging showed that the fluorescent intensity of treated group was apparently lower than that of the control. The inhibition rates of lung metastasis by LDM alone at 0.025 mg x kg(-1) and 0.05 mg x kg(-1) were 53.9% and 75.9%, respectively, while that of MTX alone at 0.5 mg x kg(-1) was 70.2%. The combination of LDM at 0.025 mg x kg(-1) and MTX at 0.5 mg x kg(-1) showed an inhibition rate of 88.7%. The coefficient of drug interaction (CDI) was 0.82. The results herein demonstrated that LDM alone had strong anti-metastasis effect on human fibrosarcoma HT-1080 and the inhibition efficacy is strengthened when combined with MTX.

[Objective]The oxidative injury of retinal pigment epithelium(RPE)plays a key role in the pathogenesis of age-related macular degeneration(ARMD). This study is to investigate the effects of endoplasmic reticulum stress and the vital transcriptional factor X-box binding protein 1(XBP1)in acrolein-induced oxidative damage of RPE.[Methods]RPE cells were treated with acrolein (75μmol/L)for 2~24 h,expression of glucose regulated protein 78(GRP78)and XBP1 was determined by Western blot analysis. After being transfected with XBP1 siRNA with 24 h,the expression of XBP1 was knocked-down in RPE cells. Protein level of Nrf2 and SOD2 was then determined by Western blot analysis and intracellular Reactive Oxygen Species(ROS)generation was determined by DCF staining. Acrolein was added for 8 h after being transfected with XBP1 siRNA or control siRNA for 24 h. Apoptosis was detected by TUNEL assay before and after the treatment. Subretinal injection of Cre or GFP adenovirus was performed in XBP 1flox mice. After 1 week the mice were sacrificed. Total RNA was extracted from mice eyecups using TRIzol and real-time RT-PCR was performed to determine the two XBP1 down-stream genes,ERdj4 and p58IPK. Cryosectioning and immunofluorescent staining were performed to look at the expression of XBP1,Nrf2 and SOD2 in mice RPE.[Results]Protein level of GRP78 was significantly un-regulated after exposure to acrolein for 2 and 4 h. XBP1 was activated after acrolein treatment for 6 h. Knock-down of XBP1 by siRNA down-regu?lates anti-oxidant genes expression and increased ROS generation in RPE cells. Loss of XBP1 exacerbates acrolein-induced cell apoptosis. XBP1 was knocked-down in the RPE of XBP1flox mice after subretinal injection of Cre adenovirus. Decreased mRNA level of ERdj4 and p58IPK,and decreased Nrf2 and SOD2 expression were seen in the Cre-injected group.[Conclusions]Acrolein induces ER stress and activates XBP1 in RPE cells. Knock-down of XBP1 down-regulates anti-oxidant genes expression ,increases ROS generation,and exacerbates acrolein-induced cell apoptosis. XBP1 plays a role in the anti-oxidant defense in the RPE cells.

ObjectiveTo analyze clinical manifestations and treatment of eosinophilic gastroenteritis (EGE) in children.MethodsThe clinical data of 10 children with EGE under the treatment from June 2014 to June 2012 were analyzed retrospectively.ResultsThere were 10 children (6 males and 4 females) aged from 9 months to 14 years. Clin-ical symptoms of eight preschool and school age children included abdominal pain (8 cases), vomiting (4 cases), diarrhea (3 cases), ascites (3 cases), rash (3 cases), fever (2 cases) and hypoalbuminemia (2 cases). Clinical symptoms of two in-fant and toddler were diarrhea and hematochezia. Peripheral blood eosinophils were increased in 10 children. IgE was elevated in 9 children. One child had very high C-reactive protein. Endoscopic examination showed mucosal congestion, swelling, erythema, erosion. Multiple sites of biopsy showed eosinophil count> 20/HP. One child was diagnosed by lap-aroscopic exploration. The treatment included diet avoidance, omeprazole, anti-allergic drug. Four children were treated with corticosteroids. All children had been followed up for 6 months to 2 years. One child had relapsed.Conclusion The clinical manifestations of EGE are various. Endoscopic biopsy is necessary for diagnosis. Laparoscopy also is help-ful for diagnosis. Dietary and glucocorticoid therapy were effective.
