Methods: Based on the data related to pneumoconiosis risk from published materials in different provinces, it used pure premium method to measure the gross premium rate and made province-specific rate tables of this liability insurance according to risk classification. Results: Rate tables of Chongqing, Shaanxi, Shanxi, Shandong, Henan and Anhui were made according to type of work and form of coal’s ownership. Conclusion: The risks of coal pneumoconiosis among different provinces are very different. It’s necessary to make province-specific rate tables when developing business of coal pneumoconiosis liability insurance for different provinces.

Objective To evaluate the value of calcium-based quantitative spectral CT imaging in differential diagnosis of benign and malignant thyroid nodules.Methods Totally 82 patients with 98 thyroid nodules confirmed by pathology underwent unenhanced and dual-phase enhanced spectral CT scans before operation.Thyroid nodules were divided into malignant group (61 nodules) and benign group (37 nodules),according to histopathologic results.Besides,contralateral normal thyroid tissue of 50 patients was selected as normal group.The calcium concentration of malignant,benign and normal group in non-enhanced scanning was analysed.The optimal threshold to predict malignancy and the corresponding diagnostic sensitivity and specificity were obtained by ROC curve.Results The calcium concentrations for malignant, benign and normal group in non-enhanced scanning were (5.52±2.72) mg/cm3, (10.72±4.68) mg/cm3 and (24.66±7.58) mg/cm3 respectively.There were significant differences statistically in any two groups (P<0.001).For malignant thyroid nodules, the best diagnostic threshold of calcium concentration was 6.065 mg/cm3,and the diagnostic sensitivity and specificity were 65.6% and 91.9% respectively.Conclusion Spectral CT imaging can quantitatively assess the calcium concentration of thyroid nodules,which provides promising quantitative approach for distinguishing malignant thyroid nodules from benign nodules.

Background Identifying and testing of pain is very necessary for the care and decrease of the suffering of experimental animal in medical experiment.Effective method for testing the pain and distress status of experimental animal with eye disease is still absent in China.Objective This pilot study was to establish an evaluating system for assessing the pain and distress status of bullous keratopathy rabbit model.Methods This study was approved by the Ethic Committee of Beijing University First Hospital.Twelve healthy New Zealand rabbits were selected in this experiment.Bullous keratopathy model was established in the left eyes of 9 rabbits by scraping corneal endothelium as the experimental team,and other 3 rabbits were served as the control team.The cornea lesion was examined by manipulate slit lamp,and the central cornea thickness (CCT) was measured by ultrasound biomicroscopy (UBM).Weight+20 Indexes For Pain and Distress Status Referring Guidelines for Pain and Distress in Laboratory Animals made by International Animal Care and Use Committee (IACUC) were assessed and measured as well.Results Corneal edema and opacity were obvious 1 day after surgery.Corneal bullous appeared from the third day after surgery,and cornea erosion was seen at the location of bullous breakage.The corneal lesions remained until 14 days after surgery.CCT value was (1468±100),(2313±588),(2391±271) and (2362±151) μm,respectively in day 1,3,7 and 14 after the establishment of models,which showed significant increase in comparison with the preoperative CCT (390±6)μm (all P=0.000).However,no significant difference was seen in the CCT between day 3,7 and 14 (P＞0.05).Body weight of the rabbits was (3.29±0.20),(3.20-0.17),(2.77±0.25) and (3.10±0.30)kg respectively in day 1,3,7 and 14 after operation,with significant decrease in comparison with the pre-operative weight (3.52-0.18)kg in the experimental team (P=0.008,0.007,0.003,0.004).The scores for pain and distress status of all rabbits in pre-operation of the experimental team and in the control team were zero,and the score was 7 (7,7),11 (10,12),9 (8,10),9 (9,9)in day 1,3,7 and 14 in the experimental team after surgery,with the highest score in day 3,which was bullous and bullous breakage duration.Seven of twenty indexes,including the reduce of diet and drinking,self-imposed isolation/hiding,grinding teeth,aggression,deceased movement,abnormal posture,vocalization occurred in the model animals after surgery.Conclusions Weight+20 Indexes For Pain and Distress Status is an effective,impersonal and quantitative method for observing and evaluating the pain and stress status in bullous keratopathy rabbit.

Objective:To analyze the characteristics of hospital infection of hematological disease, so as to provide reference for clinical therapy. Methods: Bacterial strains and antimicrobial resistance of pa-tients with hospital infection in Department of Hematology, Peking University Third Hospital from Jan. 2011 to Dec. 2013 were identified and analyzed retrospectively. The specimens were from their blood, urine, sputum, throat swabs and etc. Results:Among the total of 168 isolates of bacteria,the majority of the bacteria strains were from sputum (42. 9%);114(67. 9%) bacteria strains were gram negative and 54(32. 1%) bacteria strains were gram positive;the pathogen testing showed that 20. 8% were Pseudo-monas aeruginosa,18. 5% Escherichia coli,17. 9% Staphylococcus aureus, 9. 5% Klebsiellar pneumonia, 5. 9% Staphylococcus epidermis and 27. 4% other bacteria ;The gram negative bacilli to cefepime, ami-kacin and carbapenems showed the lowest antimicrobial resistance rates, and S. aureus showed the lowest antimicrobial resistance rates to vancomycin and linezolid. Conclusion:Patients with hemopathy are the main population of hospital infections, the gram negative bacteria are the most common pathogens. It is very important to promptly know the change in distribution of the pathogens in order to rationally select antibiotics and reduce the incidence of bacterial infections.

Aim To investigate the role of autophagy and its mechanism in Raji cell death induced by arse-nic trioxide. Methods Transmission electron micros-copy ( SEM) and MDC fluorescence staining were used to observe autophagy. MTT colorimetry was employed to assay the cellular proliferating activity. Cell apopto-sis and cell cycle analysis were performed using FITC-Annexin-V/PI double staining and flow cytometry ( FCM) . The expressions of LC3 and the conversion of LC3-I to LC3-II were measured by western bloting. The expression of bcl-2 mRNA and p53 mRNA were detected by reverse transcription-polymerase chain re-action ( RT-PCR ) . Results Arsenic trioxide could obviously inhibit the proliferation of Raji cells, arrest the cells at G2/M phase and induce apoptosis. Mean-while, arsenic trioxide markedly inhibited the expres-sion of bcl-2 mRNA and enhanced the expression of p53 mRNA in Raji cells. Arsenic trioxide also induced autophagy synchronously which paralleled with the in-duction of apoptosis in Raji cells, and 3-MA, an auto-phagy inhibitor, was able to reverse the arsenic triox-ide-activated autophagic activity, up-regulate bcl-2, down-regulated p53 expression and suppress the lethal effect of arsenic trioxide on Raji cells to reduce their sensitivity to arsenic trioxide. In contrast, the Rapamy-cin, an autophagy inducer, possessed the completely opposite effects on Raji cells compared with 3-MA. Conclusions The apoptosis and autophagic cell death are coexistent in arsenic trioxide-triggered death of Raji lymphoma cells, and Bcl-2 and p53 may play a key regulating role in this process.

Objective To explore the prevalence of anemia,iron deficiency and iron deficient anemia (IDA),and to identify their risk factors in 3 to 6 months infants in Dongcheng District of Beijing.Methods All the 845 infants aged 3 to 6 months who received bacille calmette guerin (BCG) vaccine during December 2010 and October 2011 in Hepingli Hospital of Beijing were invited to complete the investigation.Data (months,gender,birth weight,birth height,etc) were collected through a questionnaire survey.Infants were tested for hemoglobin (Hb),mean corpuscular volume (MCV),mean corpuscular hemoglobin (MCH),mean corpuscular hemoglobin concentration (MCHC),serum ferritin (SF) and zinc protoporphyrin (ZPP) and mothers underwent measurement for Hb,SF and serum iron (SI).Descriptive epidemiology and non-conditional logistic regression model were used to analyze the prevalence of nutritional anemia.Results The prevalence of anemia,iron deficiency and IDA was 12.06％,7.38％ and 2.11％,respectively.Non-conditional logistic regression analysis showed that the associated factor of anemia in infants was month age (vs.3-4 months age group,4-5 months age group:odds ratio (OR) =0.496,95％ confidence interval (CI) 0.272-0.905 ; 5-6 months age group:OR =0.494,95％ CI 0.234-1.043).The factors associated with iron deficiency were month age (vs.3-4 months age group,4-5 months age group:OR =0.539,95％ CI 0.266-1.088 ; 5-6 months age group:OR =0.334,95％ CI 0.125-0.891) and time of first breast-feeding (vs.the first day,the second day:OR =2.359,95％ CI 1.191-4.675; the third day:OR =1.154,95％ CI 0.450-2.963).Conclusions Our data show that iron nutrition in 3 to 6 months-old infants in Dongcheng District of Beijing was in good situation.The influencing factors of iron nutrition in infants may be month age and the time of first breast feeding.

Objective To explore the prenatal diagnosis and factors influencing prognosis of congenital diaphragmatic hernia (CDH).Methods Fifty seven cases of CDH prenatally diagnosed by ultrasound in the Department of Obstetrics,Xinhua Hospital from January 1,2006 to March 31,2013 were retrospectively reviewed.Prognosis and risk factors were analyzed by ultrasound characteristics and newborn status.Statistical analysis was performed using t test,x2 test and Logistic regression.Results Forty-five (79％)of all cases were left-side CDH and the rest 12 (21％)were right-side.Fourteen fetuses were aborted.Thirty three were delivered and treated surgically,twenty-three infants survived after surgery and ten died,with an overall survival rate of 40％ (23/57).The other ten cases were delivered,but died of no treated surgically.The birth weight of the surviving neonates was heavier than that of those who died [(3 173 ±348) vs (2 846±568)g,t=2.238,P=0.033].The gcstational age at diagnosis of the aborted fetuses was younger than that of the surviving neonates [(24.0 ± 4.1) vs (30.0± 6.0) weeks,t=3.181,P=0.003].Twenty-one (91％,21/23) of the surviving neonates had a lung-to-head ratio (LHR) ≥ 1.4.A linear trend test showed a negative correlation between LHR and adverse outcome (x2=9.223,P=0.002) with a correlation coefficient-0.730 (P=0.000).LHR＜1.4 (OR=35.867,95％CI:1.861-691.341,P=0.018) and polyhydramnios (OR=9.285,95％CI:1.102-78.212,P=0.040) were risk factors for neonatal death.Right-side CDH (OR=0.158,95％CI:0.009-2.824,P=0.210),liver herniation into the thorax (OR=1.730,95％CI:0.144 20.707,P=0.665) and birth weight (OR=l.002,95％CI:0.999-1.005,P=0.135) were not risk factors.Conclusions The survival rate of CDH is still low.Gestational age on diagnosis,presence of polyhydramnios and LHR＜ 1.4 predict an adverse outcome.

OBJECTIVETo compare the differences in the efficacy on depression after breast cancer operation treated with auricular point sticking therapy, the combined program of auricular point sticking therapy and TCM psychotherapy and medication with deanxit.

METHODSNinety patients were randomized into 3 groups, 30 cases in each one. In the western medication group, the simple oral administration of deanxit was applied, one tablet a day. In the auricular point group, Xin (GO15), Shen (CO10), Gan(CO12), Shenmen(TF4), Pizhixia (AT), Neifenmi (CO18) were selected and stimulated with auricular point sticking on either side in each treatment, once a week. In the combined program group, on the basis of the treatment as the auricular point group, TCM psychotherapy was combined with. The treatment of 4 weeks made one session. One session and 4 weeks follow-up were required. The self-rating depression scale (SDS) was used to compare the score before and after treatment in the patients of each group and the efficacy was assessed.

RESULTS(1) Compared with those before treatment, in 4 weeks of treatment and 4 weeks of follow-up, SDS scores were all reduced apparently in the 3 groups (all P<0.001). After 4 weeks of follow-up in the auricular point group, after 2 and 4 weeks of treatment and 4 weeks of follow-up in the combined program group, SDS scores were all lower than those in the western medication group (all P<0.05). (2) After 4 weeks of treatment, the curative rate in the combined program group was higher than that in the auricular point group and the western medication group [60.0% (18/30) vs. 40.0% (12/30), 36.7% (11/30), both P<0.05)]. After 4 weeks of follow-up, the curative rate in either the combined program group or the auricular point group was higher than that in the western medication group [60.0% (18/30), 30.0% (19/30) vs. 23.3% (7/30), both P<0.05].

CONCLUSIONThe auricular point sticking therapy, the combined program of auricular point sticking therapy and TCM psychotherapy, and medication with deanxit all relieve depression after breast cancer operation. The efficacy of the combined program with auricular point sticking therapy and TCM psychotherapy involved is the best, and the efficacy of the auricular point sticking therapy is better than the oral administration of deanxit.
