Background Glucocorticoid is a common drug for treatment of thyroid-associated ophthalmopathy (TAO) with good effectiveness.But some adverse reactions of glucocorticoid are inevitable.At recent years,99technetium-methylene bisphosphonate(99Tc-MDP) is being paid more and more attentions in the treatment of TAO,but its effectiveness and safety is worthy of comparison to traditional treatment methods.Objective This study was to evaluate the efficacy of treatment with intravenous injection of 99Tc-MDP for TAO.Methods The Cochrane Library,CNKI,PubMed,Wanfang database,Weipu net were searched in computer and Google Scholar was searched manually.The randomized controlled trail (RCT) of intravenous injection of 99Tc-MDP for TAO were collected from establishment of database through April,2012.The quality of included literature was assessed based on the methodology of the study.The evaluating indexes included the primary treating outcomes,such as total efficacy,exophthalmic extent and recurrence rate as well as secondary outcomes such as adverse effect.RevMan 5.1 software was used for Mate analysis.Results A total of 11 RCTs were identified with 706 patients.Subgroup analysis was carried out based on the outcome measures and intervention.No significant difference was found in the overall effective rate between intravenous injection of 99Tc-MDP and immunosuppressive treatment (RR =0.96,95 ％ CI:0.76 to 1.22,P=0.740).However,the effective rate was significant different between intravenous injection of 99Tc-MDP and oral prednisone (RR =1.25,95 ％ CI:1.06-1.46,P =0.007) or between intravenous injection of 99 Tc-M DP and the blank control group (RR =2.53,95 ％ CI:1.68-3.81,P =0.000).Significant difference also was found in the total effective rate between intravenous injection of 99Tc-MDP with methyprednisone and methyprednisone alone (RR =1.27,95％ CI:1.05-1.53,P =0.010).There were significant differences in the effective rate of proptosis between intravenous injection of 99Tc-MDP and oral prednisone (RR=2.02,95％ CI:1.44-3.56,P=0.020).The recurrence rate of TAO was significant different between intravenous injection of 99Tc-MDP and oral prednisone (RR =0.51,95％ CI:0.33-0.78,P=0.002).Less adverse responses were seen in the intravenous injection of 99Tc-MDP group than the oral prednisone group and immunosuppressive treatment group.Conclusions Intravenous injection of 99Tc-MDP for TAO appears to be of a similar effectiveness to immunosuppressive method.The combination of intravenous injection of 99Tc-MDP with methyprednisone seems to be more effective than methyprednisone alone,with little systemic adverse effect after application.

Abstract: Objective　To investigate the clinical characteristics and diagnosis key points of brain abscess caused by Nocardia asiatica, and provide a clinical basis for diagnosing and treating intracranial infection caused by Nocardia. Methods　A case of pulmonary Nocardia asiatica complicated with brain abscess diagnosed at the Second Affiliated Hospital of Hainan Medical University was selected to analyze the clinical manifestations, cerebrospinal fluid characteristics, pulmonary and cranial imaging features, and treatment plan, and to summarize the diagnosis and treatment experience. Results　The patient was an elderly woman with a history of diabetes, dry cough was the first symptom without fever or headache. At the beginning of the course, it was diagnosed as pulmonary infection and tuberculosis in the local hospital, and received conventional antimicrobial and anti-tuberculosis therapies, but showed no improvement. The patient developed progressive limb weakness, followed by consciousness disorders, and coma. Cerebrospinal fluid (CSF) adenosine deaminase and lactate dehydrogenase were not abnormal, CSF pressure, protein and white blood cells were high, mainly with multiple nuclear cells. CSF glucose and chloride were normal in the early stage of the disease, but decreased significantly in the later stage. Metagenomic analysis of cerebrospinal fluid indicated Nocardia asiatica with a specific sequence number of 537. Lung CT showed exudation, abscess, and cavity in the right lung. Skull MRI scan + enhancement suggested multiple scattered abscesses in both cerebral hemispheres. The abscesses were of different sizes and showed ring enhancement, with extensive surrounding edema, and ventricular compression. After treatment with meropenem, linezolid, and compound sulfamethoxazole tablets, the cerebrospinal fluid recovered, and the lesions in the lungs and intracranial structures improved. Conclusions　Brain abscess caused by Nocardia asiatica is similar to the tuberculous brain in clinical symptoms, cerebrospinal fluid examination, craniocerebral imaging, so we should be alert to the possibility of Nocardia infection in patients with diabetes. At the same time, metagenomic testing of the cerebrospinal fluid can help confirm the diagnosis. The mortality and disability rates of brain abscess caused by Nocardia are high. Early diagnosis and treatment can improve the prognosis.

Objective To investigate the renal pelvic pressure(RPP) during minimally invasivepereutaneous nephrolithotomy(MPCNL),and inspect its influence to postoperative fever. MethodsThe RPP was measured by baroeeptor,and these data about pressure and postoperative fever wereevaluated statistically. Results The mean RPP was 14.72 mm Hg,the mean accumulative time of RPP≥30 mm Hg was 116.06 s. Fifteen cases(18. 75%)had a postoperative fever. Logistical analysissuggested that postoperative fever did not correlate to sex(P=0.195),age(P=0.641),urinary tractinfection (P=0.663),white blood cell≥10 × 109/L in blood routine examination postoperatively (P=0.751),once an occurrence of RPP≥40 mm Hg(P=0.662),while infection calculi (P=0.000),percutaneous tract size(P=0.029),mean RPP(P=0.036) ,mean RPP≥20 mm Hg(P=0.013),accumulative time of RPP≥30 mm Hg(P=0.010) and RPP≥30 mm Hg longer than 50 s(P=0.024)contributed to postoperative fever. Conclusions Renal pelvic pressure generally remains lower than alevel to back flow (30 mm Hg) during MPCNL. A transient renal pelvic pressure≥30 mm Hg don'tcountribute to postoperative fever,while a temporary high pressure status(50 s)would had an accumulated effect which means an enough back flow to bring a fever.

OBJECTIVEThis study aimed to investigate the epidemiological characteristics and correlated factors of daily hassles among thermal power plant workers.

METHODSA mass screening of daily hassles and correlated factors was conducted on 498 workers from a thermal power plant in Zhengzhou in July, 2008. The questionnaires included Daily Hassles Questionnaires, Work Roles Questionnaires, Job Content Questionnaires (Chinese version), Effort-Reward Imbalance (Chinese version), Work Locus of Control Scale and Type A Behavior Scale, with content covering demographic characters and occupational stress correlated factors among subjects. The daily hassles was divided into lower level and higher level according to scores, and the epidemiological characteristics and correlated factors of daily hassles were analyzed.

RESULTSA total of 446 qualified questionnaires were obtained, effective response rate was 89.6% (446/498). For respondents, the age was (36.96 ± 6.49) years old, working length of the current job was (12.05 ± 7.54) years, the daily hassles scores was (9.01 ± 2.50), and the prevalence rate of the higher level of daily hassles was 34.1% (152/446). The multiple non-conditional logistic regression analysis showed 5-14 years' working length of current job (OR = 0.451, 95%CI: 0.225 - 0.904), average income > 3000 yuan(OR = 0.372, 95%CI: 0.202 - 0.684), reward (OR = 0.557, 95%CI: 0.325 - 0.954) and coping strategy (OR = 0.552, 95%CI: 0.330 - 0.925) were negatively correlated with daily hassles, and shift-work (OR = 1.887, 95%CI: 1.108 - 3.215), effort (OR = 2.053, 95%CI: 1.198 - 3.519), psychological demand (OR = 1.797, 95%CI: 1.049 - 3.078), negative affectivity (OR = 3.421, 95%CI: 2.065 - 5.668) were positively correlated with daily hassles.

CONCLUSIONThe prevalence rate of the higher level of daily hassles was considerable high for thermal power plant workers. Its negative correlated factors included 5 - 14 years' working length of the current job, average income > 3000 yuan, reward and coping strategy and its positive corelated factors included shift-work, effort, psychological demand and negative affectivity.

OBJECTIVETo study the regulation of luteolin on spleen cells and sarcoma S180 cells in normal ICR mice.

METHODSSpleen cells and S180 cells were incubated with different concentrations of luteolin (50, 100, 200, and 400 μmol/L). The effect of luteolin on spleen cells and sarcoma S180 cells was determined by MTT assay. The apoptosis was detected using propidium iodide staining flow cytometry. Intracellular reactive oxygen species (ROS) was determined by flow cytometric analysis. Activities of free radicals scavenging were determined by hydroxyl radical and DPPH tests.

RESULTSCompared with the solvent control group, 200 and 400 μmol/L luteolin increased the spleen cells viability (P < 0.05). Luteolin at 100, 200, and 400 μmol/L decreased activities of S180 cells (P < 0.01). The proportion of sub-G1 phase spleen cells was reduced after treated with 200 and 400 μmol/L luteolin (P < 0.05). The proportion of sub-G1 phase S180 cells was elevated after treated with 200 and 400 μmol/L luteolin (P < 0.05). Compared with the solvent control group, levels of intracellular ROS in spleen cells of ICR mice all increased; levels of intracellular ROS in S180 cells all decreased after treated with 50, 100, 200, and 400 μmol/L luteolin (P < 0.05). Luteolin scavenged hydroxyl radical and DPPH in a dose dependent manner.

CONCLUSIONLuteolin had bilateral regulation on viability and apoptosis of spleen cells and S180 cells (promoting the viability of spleen cells, inhibiting apoptosis of spleen cells, inhibiting the viability of S180 cells, and promoting apoptosis of S180 cells), which was worth further study and exploration.
