Objective:To investigate the relationship between changes of the concentration of IL -12,IL-4,IFN-γwithin cervical local immune microenvironment and cervix infected with HPV 16,58,to understand the prevalence of physical status of HPV 16/58 DNA into the host genome in cervical lesions of different grades and to detect the relation between the integrated state of virus and the progress of cervical lesions.Methods: Detecting 89 cases of cervicovaginal lavage fluid and 140 cytological specimens of the cervix which from patients having had HPV-DNA genotyping assays and coming from the Affiliated Tumor Hospital of Guangxi Medical University from 2012.8 to 2013.5.89 cases of cervicovaginal lavage fluid were divided into 58 cases of HPV16 (+) and 31 cases of HPV58(+).Cytokines IL-12, IL-4, IFN-γin the cervical microenvironment were detected by ELISA assay.140 cases of cervical exfoliated cells were divided into 106 cases of HPV16(+) and 34 cases of HPV58(+).Using qRT-PCR to quantify the copy number of E2 and E6 genes and analyze the physical status of HPV 16/58 DNA according to E2/E6.Results:①The level of IL-4 in HPV16(+) was significantly higher than that in HPV58(+)(P<0.05).The levels of IL-12 and IFN-γwere lower than that in HPV58(+)(P<0.05).②Significant differences of DNA state were found between the groups of HPV 16(+) and HPV58(+)(P<0.05)and the rate of HPV16 DNA integration was significantly larger than that of HPV 58 DNA.Conclusion:The infection of HPV16 and HPV58 not only can lead to reduction of IL-12,IFN-γand increasing of IL-4 in cervical local immune microenvironment but also lead to viral integration in cervical cells,resulting in cervical lesions and cervical cancer through the internal and external changes in cervical cells .HPV16 is more likely to cause cervical cancer tissue than 58.

Hypoplastic myelodysplastic syndrome(Hypo-MDS),with the derangement of BM texture,is characterized by the hypoplasia of bone marrow(BM)accompanied with the deterioration of MDS. Hitherto there isn't a definite therapeutic definition about Hypo-MDS. Is therapy should be paid more attention to. This article introduces the study of therapy of Hypo-MDS.

Thymomas are most frequent primary tumors of anterior mediastinum.Surgery is the principal treatment method.Thymomas are sensitive to chemotherapy,and chemotherapy has showed a sig- nificant anti-tumor effect in locally advanced,recurrent or metastatic thymomas.Chemotherapy,radiother- apy or combined chemotherapy and radiotherapy before or after operation can offer patients excellent re- sponses,improve resectable rate.Some patients who are once inoperable obtain curative and palliative operation.Radiotherapy after operation can decrease residual tumor tissue,increase local control,de- crease recurrence,and prolong the survival.The multimodality therapy plays an important role in thy- moma treatment.

0.05 ). Conclusions Both ultrasonography and helical CT can demonstrate hemodynamics of hepatic tumors sensitively and accurately, which is helpful in differential diagnosis of hepatic tumors.

The mechanisms of food allergy include IgE-mediated and non IgE-mediated immune responses.Food intolerance is the reaction of defected digestive function caused by many factors in which the immune system is not involved.Clinically,the cases of food intolerance are increasing and the symptoms of the disease are usually complicated.Clinicians are facing the problem of differential diagnosis of food allergy and food intolerance,this article reviews the mechanisms of these two diseases to provide the reference for differential diagnosis.

Background Cataract surgery with replacement of the natural lens with an artificial intraocular lens(IOL) has developed into refractive surgery.Visual acuity is not the only evaluation criterion,but more focus has been put into the visual quality postoperatively.Aspherical IOL could improve the visual quality by decreasing the aspherical aberration.Objective This study was to investigate the short-term visual acuity,aberration alteration and clinical application of unsteady aberration aspheric IOL.Methods A retrospective case-controlled study was designed.Forty-two eyes of 30 patients with age-related cataract were included and divided into two groups.Phacoemulsification combined with unsteady aberration aspheric IOL implantation was performed in 21 cataractous eyes of the ZO group,and phacoemulsification combined with spherical IOL implantation in the other 21 eyes of the ADAPT group.Visual acuity,best corrected visual acuity (BCVA),contrast visual acuity,spherical aberration of the whole eye,contrast sensitivity (CS),dare sensitivity,modulation transfer function (MTF) and apparent accommodation were measured three months after surgery.All the parameters were compared between the two groups.The correlation of CS with the root mean square of spherical aberration,root mean square of comatic aberration and age was analyzed by multiple linear regression analysis.Written informed consent was obtained from each patient prior to operation.Results No significant differences were found in unconnected visual acuity,BCVA and spherical degrees between the ZO group and ADAPT group 3 months after surgery(P＞0.05).The CS value in the ZO group was significantly higher than that of the ADAPT group under scotopic background condition with spatial frequencies of 6,12,18 cpd,low glare the spatial frequencies of 6,12 cpd,as well as high glare with 12,18 cpd(P＜0.05).Under a scotopic background with 100％ contrast or a photopic background with 5％ contrast,the contrast visual acuity of the ZO group was significantly higher than that of the ADAPT group (t =20.217,P =0.000 ; t =4.568,P =0.039).At pupil diameters of 3,4 and 5 mm,the Z4 value was significantly lower in the patients of the ZO group than that of the ADAPT group (U =63.000,P =0.000 ; U =52.000,P =0.000 ; U =36.000,P =0.000).However,no significant differences were seen in the Trefoil aberration (Z6)value at 3 mm and 4 mm of pupil diameter(U =204.000,P =0.678;U =215.000,P =0.890) and coma aberration (Z7,Z8) value at 3,4 and 5 mm of pupil diameter between ZO group and ADAPT group(Z7:U=156.000,P =0.159 ; U =196.000,P =0.538 ; U =199.000,P =0.587 ; Z8:U=163.000,P =0.148 ;U=214.000,P =0.870;U =143.000,P =0.061).When the pupil diameter was 5 mm,Z6 value was significantly lower in the patients of the ZO group than that of the ADAPT group (U =4.000,P =0.000).The higher-order aberration MTF was significantly elevated in the ZO group compared with the ADAPT group from 5 through 20 cpd at a pupil diameter of 4 mm (P＜0.05) and 10,20,25,30 cpd at a pupil diameter of 5 mm (P＜0.05).A slightly lower objective accommodation was found in the ZO group compared with the ADAPT group without statistically significant difference(t =0.003,P＞0.05).Multiple linear regression analysis showed that the change in CS was associated with the root mean square of the spherical aberration and IOL type(β=0.544,R2=0.519,P =0.000)rather than with the root mean square of the comatic aberration and age.Conclusions The postoperative visual quality in the unsteady aberration aspheric IOL implanted eye is superior to that in the spherical IOL implanted eye due to a reduction in spherical aberration.

OBJECTIVE: To study the expression of S100B and glial tibrillory acidic protein (GFAP) atter primary brainstem injury in rat and discuss the changes with brainstern injury time and their mechanism in the injury. METHODS: The brainstem injury animal model was established using the mechanical impacting method. The HE staining, Gless argentaffin staining and SP immunohistochemical method were applied to observe the changes of S100B and GFAP at different injury time. The immunostaining results were measured statistically with imaging analysis technology. RESULTS: A large number of S100B positive cells could be seen in 30 min. Afterward, expression increased gradually with time and peaked up in 24 h, and reversed back the normal in 72h. The GFAP positive cells showed rise continually in 30 min, and reached the peak in 48 h, then started to decrease, but still higher than that in control. CONCLUSION The expression of S100B and GFAP is correlated with post traumatic intervals after brainstem injury in rat, and may be useful in estimation post traumatic intervals and nerve regeneration.
