Objective To investigate the prevalence of pulmonary acariasis among the employees working on traditional Chinese medicinal materials and observe the effect of treatment. Methods History inquiry, detection of mites in sputum, blood examination for eosinophils and specific antibodies, x-ray chest film were carried out for 327 workers involving in traditional Chinese medicinal materials. Mites were found in sputum in 121 persons who were then treated with metronidazole, twice a day with a daily dosage of 0.8g for seven days as a course of treatment. Two courses were conducted with an interval of 7-10 day. Prevalence and morbidity in different groups of occupation, age, and sex were analyzed. Results The overall infection rate of mites in sputum was 37.0% (121/327) with an average morbidity of 12.5% (41/327). Among the four types of worker investigated, the highest infection rate (51.8%), and morbidity (18.6%) were in those working in transfer warehouse; the second highest infection rate (40.7%) and morbidity (15.7%) were in employees in factory of Chinese traditional medicine. Both groups showed a significant difference with others(?2inf=11.36,P0.05). After treatment with metronidazole, 88.4% showed negative in sputum examination for mites and the efficacy of the treatment for pulmonary acariasis was 92.3%. Conclusions Employees engaged in traditional Chinese medicinal materials are one of the groups at the highest risk of pulmonary acariasis. Metronidazole is effective in treating the infection.

OBJECTIVETo observe the effect of Fengshi No. 1 (FS1) in treating patients with active stage of rheumatoid arthritis (RA).

METHODSPatients with RA were randomly divided into two groups, the 40 patients in the treated group were treated with combined therapy of methotrexate (MTX), sulfasalazine (SSZ) and FS1, and the 20 in the control groups were treated with MTX and SSZ alone.

RESULTSIn the treated group, the total effective rate was 97.5%, the clinical controlled and markedly effective rate 95.0% and the occurrence rate of side-toxic reaction 10.0%, as compared with those in the control group, 60.0%, 20.0% and 45.0% respectively, the difference was significant (chi 2 = 11.91, 32.23 and 7.67 respectively, all P < 0.01). The effect in the treated group was superior to that in the control group in abating joint swelling and pain, improving function of joint, reducing immune indices and ameliorating iconographic features (P < 0.01 or P < 0.05).

CONCLUSIONFS1 not only has the effects of anti-inflammation, analgesis, regulating immune reaction, but also could retard the occurring of bone destruction, reduce the toxic-side effects of MTX and SSZ.

The 1.23 kb DNA fragment encoding the early protein EP0 of pseudorabies virus (PRV) Ea strain was amplified by PCR technique and cloned into pBluescriptII sk+.Three sequencing plasmids containing the partial fragment of the EP0 gene were constructed and the sequences were obtained by Sanger's sequencing technique. Compared with PRV InFh strain, there were multipile site-mutations and a deleted-mutation in the EP0 gene of PRV strain Ea，and the diversity of amino acid residues also existed.Then, the EP0 gene was inserted into an expression vector, pET-28a, fused into the downstream of the 6ΧHis-Tag in frame, to yield the expression plasmid pETEP0. After induction by IPTG, a high expression of fusion protein was obtained, SDS-PAGE analysis and Western blotting showed that the fusion protein was 62kD and the protein was specific to antisera against PRV Ea strain. This indicated that the EP0 gene be expressed in BL21(DE3) and the expression products have immuno-genicity.

Medical parasitology education has been facing some difficulties because it is a course of wide range lacking clini?cal cases and concerned specimens of parasites currently. In addition its relationship with life is not closely enough. All these reasons may impact the effect of class education negatively. Therefore it is important to increase the vitality of parasitology edu?cation and diversify the instructional mode by using the resources from Internet. In recent years the Discovery Channel has up?loaded a documentary Monsters Inside Me online. This documentary is high professional and closely linked with parasitology. It maintains numbers of clinical cases about parasitic diseases. Each episode is about 3 minutes and shortly enough to be intro?duced into class teaching. However this resource has not been fully used in domestic temporally. We found that direct introduc?tion of the documentary into class teaching can enrich teaching forms to attract learning interest of students and finally improve the teaching effect of class. Above that another popular documentary A Bite of China involves many related knowledge points of parasitology. The appropriate usage of the knowledge can build up close linkage between book and life which is extremely help?ful to give students a deep impression of parasitology. In brief it is our strong recommendation to introduce the documentary Monsters Inside Me into class.

Objective To evaluate the effect of digital subtraction angiography and transcatheter embolization for gastrointestinal hemorrhage.Methods Twenty patients with gastrointestinal hemorrhage received celiac arteries,superior mesenteric arteries and inferior mesenteric arteries angiography. Superselective angiography were performed when the arteries were suspicious by clinic or angiogrraphy.Ten patients with definite diagnosis and manifestation of hemorrhagic arteries by angiography were embolized after superseleetive catheterization with gelfoam particles,gelfoam particles and coils,polyvinyl alcohol particles. Results The positive signs were observed in 13 cases.The DSA features including contrast medium accumulation in the gastrointestinal tract outside vascular,aneurysm,tumorous vascularization and staining, artery affect and local vasospasm.The bleedings were stopped immediately in 8 patients.No rebleeding and intestinal ischaemia or necrosis were observed in 30 days.One patient died in the second day after embolization from multiple organ failure.Rebleeding occurred 3 days after embolization in another patient, and was recovered after surgical operation.Conclusion DSA is more effective for the diagnosis of gastrointestinal vascular malformation and tumors complicating acute bleeding.Transcatheter embolization is effective and safe to control the hemorrhage.

Objective To investigate anxiety and its influencing factors of the nursing students before taking nurse qualification tests in Xi' an.Methods 1 531 nursing students were randomly selected by cluster sampling method and surveyed with Sarason' s Test Anxiety Scale (TAS) two weeks before the test.One-way ANOVA was adopted to analyze the influencing factors.Results The TAS score of nursing students at different education levels was (19.45:±6.24) from 1 527 surveys collected.One-way ANOVA showed the variables that had significant differences were worrying about the future career,confidence of passing the tests,worrying about others opinions of failing,the attention schools paid,current education of the students,attitudes of the nursing profession,and the efforts students paid for the tests ( F =27.865,22.423,20.925,13.838,7.565,5.357,4.283,respectively; P ＜ 0.01 ).Personalities of the students and whether continue working before the tests also showed significant difference (t =4.178,2.802,respectively;P ＜0.01 ).Conclusions Nursing students from Xi' an showed middle level of anxiety before taking nurse qualification tests.Influencing factors of the anxiety included worrying about the future career,confidence of passing the tests,worrying about others opinions of failing,the attention schools paid,personalities of the students and whether continue working before the tests.

Objective To understand the experience and coping styles of college students with pulmonary tuberculosis.Methods By purposive sampling method,15 tuberculosis college students were selected to do an indepth interview in Xi' an city.The data were analyzed by the thematic framework.Results The experience of students with pulmonary tuberculosis included self-stigma,other students keep them at a distance,being shunned by neighbours and being treated differently by some policise.And the coping styles of them included self-isolation,concealing the disease,not satisfied with the policy and rationalization.Conclusions Health education about pulmonary tuberculosis should be strengthen,and more care should be paid on the pulmonary tuberculosis college students.We should try to make a good learning,living and treatment environment for them so as to promote them to cope tuberculosis more scientifically.
