As our country lack professionals of public health,higher demand to the preventive medicine is further made with the transformation of medical model and the construction of the public health system,and the reformation in preventive medicine education of higher learning is explored to cultivate the practical professionals of public health by modulating education program and courses,modifying the cultivating plan,emphasizing the knowledge of liberal arts and management,strengthening the cultivation of ability and combining theory with practice.

BACKGROUND:Bioactive glass has been largely reported to have perfect clinical results in the bone nonunion and fracture healing, but its effect during spinal fusion progress is rarely reported.
OBJECTIVE:To explore the safety and effectiveness of anterior cervical discectomy and fusion by cervical cage with bioactive glass
METHODS:A total of 68 cases of cervical spondylosis myelopathy were treated with single level anterior cervical discectomy and fusion. Their clinical data were retrospectively analyzed. Al the cases underwent polyetheretherketone cervical cage with autogenous bone (n=32, control group) or bioactive glass (n=32, experimental group). The bone fusion, neurological functional recovery, intervertebral height, change of cervical curve and wound complications in the two groups was recorded and analyzed.
RESULTS AND CONCLUSION:Neurological improvement had no difference between the two groups and there was no complication about wound, such as infection and delayed healing. The average rate of bone fusion was 97%in the control group while 94%in the experiment group 3 months after operation which had no significant differences. Six months after operation, al cases gained bone fusion. The intervertebral height and change of cervical curve both maintained wel in the two groups within 3, 6, 12 months after operation which had no significant differences between the two groups. So, anterior cervical discectomy and fusion by cervical cage with bioactive glass is safe and effective.

AIM: To investigate the indications and therapeutic effect of the conservative treatment and surgical treatment for vitreous hemorrhage.
METHODS: Hemorrhage reasons, degree of illness, and treatment and final results of vitreous hemorrhage were recorded from 2008 to 2013, and curative effect of different treatments was analyzed.
RESULTS:Selected 22 cases ( 24 eyes ) of conservative treatment, vision degree of 6 eyes ( 25%) had raised, 5 eyes ( 21%) occurred secondary retinal detachment without treatment, 3 eyes (12. 5%) suffered neovascular glaucoma were underwent operation, but the vision had lost completely. In 26 cases ( 31 eyes ) of control (operation) group, vision of 17 eyes (55%) had improved, 2 eyes (6. 5%) suffered the second operation, 2 eyes (6. 5%) suffered the third surgery, 3 eyes (10%) suffered eyeball atrophy. The number of ultimate vision improved with conservative treatment were significantly lower than the number of cases with surgical treatment (P<0. 05).
CONCLUSION: The surgical treatment is still visible vitreous hemorrhage treatment means of positive, but there will be eyeball atrophy and other serious complications, so we should choose a different methods in according to the different treatment objects and treatment time.

Objective To evaluate the clinical value of 99Tcm-MIBI SPECT for the differential diagnosis of parotid tumors before treatment.Methods 99Tcm-MIBI SPECT imaging of the parotid region was obtained in 32 patients with parotid tumors before surgery.Early and delayed 99Tcm-MIBI imaging were performed in all patients and the diagnosis was confirmed by pathological results after surgery.The ratio of radioactivity between the tumor and opposite side of normal parotid tissue (T/N) was measured.Fisher exact probability test and t test were used for statistical analysis.Results The sensitivity,specificity and accuracy of 99Tcm-MIBI SPECT imaging for the differential diagnosis of parotid tumor were 90.00％ (9/10),86.36％ (19/22) and 87.50％ (28/32),respectively.Among 22 patients who had benign tumors,19(86.36％) showed negative findings,and the other 3 ( 13.64％ ) patients showed false positive results.In 10 patients with malignant tumors,1 ( 10.00％ ) had false negative findings,and all the other 9 (90.00％)patients showed positive results.The difference between the benign and malignant groups was statistically significant (P =0.00018 ).In the early images,the T/N ratios of benign and malignant parotid tumors were 1.45 ±0.38 and 1.65 ±0.63 (t =20.4,P＜0.01),respectively; and in the delayed images,the ratios were 1.43 ± 0.56 and 1.77 ± 0.59 ( t =2.4,P ＜ 0.05 ),respectively.Conclusion 99Tcm-MIBI SPECT imaging might be useful for the differential diagnosis of parotid tumors before surgery.

Objective To analyze gerbil plague in northern Ningxia and the monitoring results,to master the plague epidemic dynamics,and to provide the basis for developmenting countermeasures.Methods Monitoring data of gerbil plague focus in northern Ningxia were collect in 2009,counted main host density,rate of dye fleas,flea body index and bacteriology,serology detect and analyzed the epidemic situation.Results An average density of main host was 1.74/hm2,the average rate of infected fleas was 28.60％,and the average rat body flea index was 0.76.Monitoring found 4 plagues from rat plague epidemic,plague bacteria were found in 16 strains,of which gerbils inspection bacteria 10 strains,Meriones unguiculatus 2 strains,the same type cheopis 2 strains,and bald disease fleas 2 strains.Indirect hemagglutination (IHA) was used to test 529 copies of samples,2 copies were found positive,and hemagglutination-positive rate was 0.38％; eight copies were examined by reverse indirect hemagglutination(RIHA),7 material were found positive,and hemagglutination-positive rate was 87.50％.Conclusions In recent years,the disease is active among animals in gerbil plague focus Ningxia.The density of rodents is higher,and local plague epidemic is found in rats.Monitoring efforts should be strengthened and scope of monitoring should be expanded.We should pay close attention to the epidemic dynamics,control the prevalence and spread of animal disease,and prevent the occurrence of human plague.

Objective To explore the signaling pathway of AP-1 activated by epidermal growth foctor receptor(EGFR) in the rat gastric mucosal cells. Methods TGF-? stimulated freshly isolated rat gastric mucosal cells,and Western blot and EMSA detected the activation of ERK-1/2 signaling pathway. Results The exposure of the mucosal cells to 1 nmol/L TGF-? for 30 min significantly induced transcriptional activity of AP-1. This induction was associated with a concomitant activation of MEK and ERK-1/2. TGF-?-induced activation of AP-1 in gastric mucosal cells could be totally abrogated by either PD153035, a specific inhibitor of EGFR tyrosine kinase, or PD98059, a specific inhibitor of MEK. Conclusions Our findings suggest that EGFR AP-1 activates by EPK-1/2 signaling pathway in the rat gastric mucosal cells.

Objective To investigate the effects of short-segment pedicle screws system on type A thoracic and lumbar spine fracture with or without pedicle screws on the fractured level. Methods 23 patients with type A thoracic and lumbar spine fracture were included, in which 11 cases received traditional short-segment pedicle screws system without pedicle screws on the fractured level (group A), and other 12 cases with pedicle screws on the fractured level (group B). The anterior vertebral height, posterior vertebral height and local kyphosis an-gle were measured before and after operation. Results All pedicle screws were successfully implanted with good location and stability. The vertebral height and kyphosis angle significantly improved after operation in both groups (P<0.05), and the improvement of kyphosis angle was more in group B than in group A (P<0.05). Conclusion Short-segment pedicle screws system with pedicle screws on the fractured level may fine correct the kyphosis angle in short term.

Ikaros is a regulatory factor playing an important role in control of the development of hema-topoietic cells and immune system;and as a tumor suppressor,its aberration can cause both T and B lineage development arrest and neoplastic transformation,leading to insensitive to therapy and poor prognosis in actue lymphoblastic leukemia. Recently,researches on how Ikaros affects the leukemogenesis and prognosis become the focus of attention.
