Objective To evaluate the mental health of medical workers, and develop an EAP suitable for heahhcare sector. Methods A 1-year EAP was implemented in a hospital in Beijing, in which SF-36 and JSS scales were used to study the health-related quality of life and job satisfaction of these workers. Results Work pressure is found to be the main source of pressure for medical workers, accounting for 63.7%. Scores of the group receiving EAP service are found to be significantly higher (P<0.01) in all dimensions (excepting work nature and supervisor dimension) of both SF-36 and JSS. Conclusions Medical workers are exposed to high pressure of work, having strong need for EAP service as result. EAP is an effective means to maintain mental health and improve quality of life and job performance, if applied widely.

OBJECTIVETo investigate effectiveness of scopolamine on the acute severe chlorphenamidine poisoning patients.

METHODS72 cases of acute severe chlorphenamidine poisoning patients were divided into I and II groups by the principle of a 1:1 sampling according to the order of admission. The I group (36 cases) were treated with traditional multimodality therapy, including gastrolavage, catharsis, using reductant-oxidant (methylthioninium chloride and vitamin C), and symptomatic treatment. The II group were treated with traditional multimodality therapy and scopolamine at the same times. Blood methemoglobin were measured at 0, third, seventh, twelfth, twenty-fourth hour, serum troponin I (CTnI) and creatine kinase isoenzyme (CK-MB) levels at third, seventh, twenty-fourth, forty-eighth hour, hepatic and renal functions at third, twenty-fourth, forty-eighth hour, and electrocardiogram (ECG) were evaluated every 4 hours in 3 days after hospitalization on all patients. The two groups of patients were compared the efficacy and change detection of targets.

RESULTS31 patients (86.11%) recovered and 5 patients (13.89%) died in I group. All 36 cases recovered in II group. The recovery rate of II group was distinctively higher than that in I group (P < 0.05) and the difference was statistically significant (P < 0.05). The average recovery time and the length of hospital stay in II group were sharply shorter than those in I group (P < 0.01) and the difference was statistically significant (P < 0.05). Serum CTnI levels between seventh hour and forty-eighth hour, serum CK-MB levels between third hour and forty-eighth hour and methemoglobin concentration at third, seventh, twelfth, twenty-fourth hour were apparently lower in II group, and the difference was statistically significant (P < 0.05). The abnormal rates of hepatic and renal functions in II group were distinctively lower than those in I group and the difference was statistically significant (P < 0.05). The abnormal rates of ECG in the second and third day in II group were respectively 38.89% and 11.11%, and were lower than those in I group (64.71%, 38.71%). The difference was statistically significant (P < 0.05).

CONCLUSIONScopolamine has the excellent treatment effect on acute severe chlorphenamidine poisoning patients and protec their hearts, livers, and kidneys. It complements the deficiency of reductant-oxidants, and combination of the two drugs can form the synergy effect.

The complete chloroplast genome of medicinal plant Asarum caudigerum Hance and its close relative A. cardiophyllum Franchet were sequenced using Illumina Hiseq technology, and assembled, annotated, and characterized by bioinformatic methods in this study. Then phylogenetic analysis of the complete chloroplast genomes of A. caudigerum, A. cardiophyllum, and twelve published species was conducted. The results indicated that the chloroplast genomes ranged from 186 215-186 985 bp in length, with a large single copy (LSC, 89 445-90 169 bp) and two inverted repeats (IRa/IRb, 48 387-48 408 bp). The overall GC content was 37.4%-37.5%. A total of 144 chloroplast genes were annotated, including 98 protein coding genes, 38 tRNA genes and 8 rRNA genes. In addition, complex genomic rearrangements were detected in the chloroplast genome of Asarum. Meanwhile, visual evaluation of the discrete type of the sequence indicated that the variation level of non-coding region was higher than that of coding region. Phylogenetic analyses suggested that A. caudigerum and A. cardiophyllum were clustered into a single clade and A. cardiophyllum, A. sieboldii var. seoulense, A. misandrum and A. maculatum were clustered into another single branch. These two clade were sister species. This study provides a scientific basis for the identification, phylogenetic relationship, molecular breeding of Asarum species.

In order to enhance the antitumor efficacy of recombinant Newcastle disease virus, rNDV-IL15 was rescued in this study. Recombinant plasmid prNDV-IL15 was constructed, and BHK21 cells were transfected with the recombinant plasmid. Finally, the recombinant Newcastle disease virus rNDV-IL15 was successfully rescued. The growth curves of these two recombinant viruses were determined. Murine melanoma B16F10 cells were infected with rNDV-IL15 at MOI of 0.1, and the expression level of IL15 in the supernatant was detected by ELISA. The antitumor efficacy of rNDV-IL15 and rNDV was compared in vitro and in vivo. Results showed that prNDV-IL15 was constructed and recombinant virus rNDV-IL15 was successfully rescued. The growth curve of rNDV-IL15 showed that the growth of rNDV-IL15 had not been changed after insertion of IL15 gene. Results showed that there was high level of IL15 expression in the supernatant of rNDV-IL5-infected B16F10 cells (1 044.3 +/- 27.7 ng x mL(-1)). rNDV-IL15 and rNDV significantly inhibited the growth of B16F10 cells in vitro in a time-dependent manner. However, there was no significant difference between them. In animal experiments, rNDV-IL15 efficiently suppressed tumor growth in vivo when compared with rNDV, and the difference was statistically significant. The results suggested that rNDV-IL15 is a more effective antitumor agent.

Uterine leiomyosarcoma is an uncommon malignant neoplasm of smooth muscle origination and is associated with a poor prognosis. We report two cases of uterine leiomyosarcoma that presented with pulmonary metastases. 2-deoxy-2-(¹⁸F)fluorodeoxyglucose (FDG) positron emission tomography (PET)/computed tomography (CT) was performed to identify the primary carcinoma and found the focus located in the uterus. The follow-up magnetic resonance imaging (MRI) confirmed the diagnosis was uterine leiomyosarcoma.
