Objective To discuss the femoral neck anteversion(FNA) of developmental dislocation of the hip(DDH) and guide operation with visual and digitalized picture in the dimensional(3D) CT.Methods Ninety children with unilateral DDH were selected,and they were analyzed using 3D CT.Children whose FNA exceed 45 degree received the subtrochanter osteotomy with images from different direction,FNA of hip was measured respectively before and after operation and was measured in normal and abnormal hips respectively,FNA of hip received respectively statistical treatment.Ninety patients (90 hips) were followed up ranging from 3 months to 2 years with the mean of 13 months.Results In the group younger than 18 months,the FNA whose in normal hips was(19.40?3.512)degree,the FNA while(68.45?12.272)degree in dysplasia hips respectively,the FNA measured after operation was (20.45?2.940) degree;in the group elder than 6 years,there were significantly statistical differences,the FNA in normal hips was(19.44?3.561)degree,in dysplasia hips respectively was(73.49?12.678)degree,while the FNA measured after operation was(18.28?1.931)degree.Clinical assessment was performed according to Mckay′s classification.The results showed that the overall excellent or good rate was 95.6%.Conclusions 3D CT method is a new accurate and convenient and reduplicative method for measuring FNA.It will be more helpful for related operations when 3D images are considered.

The diversity in Tibetan kefir grains and dynamics of the microbial community during the fermentation of Tibetan kefir by PCR-DGGE fingerprinting technique were studied.The results showed that bacterial community of Tibetan kefir grains was more complex than that of yeast.The bacteria communities between different Tibetan kefir grains showed 78%～84% similarity, and yeast 80%～92%.Bands B, E and N of DGGE profiles of the microbial community during fermentation of Tibetan kefir were present throughout the fermentation.Analysis of sequence date showed the majority of the DGGE bands of bacteria community corresponded to LAB, and the most intense band (band E) was completely homology to Lactococcus lactis.

Background In the past few decades,the balance of Th1/Th2 is often used to explain the immune mechanisms of fungal infection and fungal disease.More recently,a novel subset of CD4+ effector Th cells has been found to participate in anti-fungal infection response.However,whether Th17 is involved in the immune response in fungal keratitis is unclear up to now.Objective Present study was to investigate the expression change of Th17 type cytokine and its specific transcription factor,retinoid-related orphan nuclear receptor gamma t (RORγt),in the cornea of Fusarium solani keratitis.Methods Ninety-six clean BALB/c mice were divided into Fusarium solani keratitis model group and control group by randomized digital table.Fusarium solani keratitis models were established by epikeratophakia-assisted corneal epithelial erasion and interlayerly injection of 5 μl (1 × 106 CFU/ml) Fusarium solani solution in the right eyes,and the equal volume of PBS was injected in the same way in the control group.10％ KOH wet film was used to examine the fungal hyphea and funga strain was identified by inoculation.The corneas were examined under the slit lamp microscope 1 day,3,5,7 days after modeling and the inflammatory response was scored based on the criteria of Wu and Hu.The histopathological examination of corneas was performed in the time points above.Real time fluorescence quantitative PCR was used to detect the expression levels of interleukin-17 (IL-17) mRNA and RORγt mRNA in the corneas.The expression of IL-17 protein in the corneas was detected by ELISA.The use and raise of the mice followed the Statement of Association for Research in Vision and Ophthalmology.Results The inflammatory scores were 3.2±0.8,6.6± 1.1,9.4± 1.1 and 6.8±0.8 in 1 day,3,5,7 days after modeling,showing a significant difference among them (F =89.786,P =0.010).The inflammatory scores were higher in the third and seventh day than that in the first day (P＜0.05),but they were significantly lower than that in the fifth day (P＜0.05).The infiltration of inflammatory cells showed a coincident tendency with the score.The expressing levels of IL-17 mRNA (2-ΔΔCt) in the corneas were 4.12±0.73,20.72±1.81 and 14.16±1.88 in 3,5,7 days after modeling,with statistically significant differences in comparison with those in the control group (P＜0.01),and the expression level was significantly higher in the fifth day than those in the first,third and seventh day in the model group(P＜0.01).The expression levels of IL-17 protein (ng/g) were significantly increased 1 day,3,5,7 days in the model group compared with the control group (P＜0.01).A similar change was found in the expression of RORγt mRNA to that of IL-17 mRNA.Conclusions Expressions of IL-17 and its transcription factor RORγt upregulate in the fungal keratitis and has an association with inflammatory degree,which suggests that Th17 subset may play an important role in the immune responses of fungal keratitis.

AIM:To study the effect of different surgeries for vision and postoperative complications in leprosy patients with lagophthalmos.METHODS:A retrospective analysis.Totally 68 leprosy patients (97 eyes) with lagophthalmos were selected who treated with different surgeries during May 2007 to September 2015 in our sanatorium.The surgeries included nylon thread correction surgery, tarsorrhaphy, temporalis transposition surgery.We observed and compared the best corrected visual acuity(BCVA) and the rate of postoperative complications, such as epiphora, lacrimal duct injury, hard to open eyes, infection at the inner and lateral canthus and scar formation of lacrimal apparatus.RESULTS:The effect on BCVA of patients treated with nylon thread correction surgery and tarsorrhaphy:the preoperative and postoperative BCVA was significantly different of the two groups (Z=-4.193,-4.213;P<0.05);the preoperative and postoperative BCVA was not significantly different of the patients underwent temporalis transposition surgery (Z=-1.532, P >0.05).The postoperative complications:(1) epiphora:there was 91% in patients underwent nylon thread correction surgery, 89% in patients underwent tarsorrhaphy, 59% in patients underwent temporalis transposition surgery, the difference was statistically significant (χ2=12.198, P<0.05);(2) lacrimal duct injury:there was 66% in patients underwent nylon thread correction surgery, 95% in patients underwent tarsorrhaphy, 41% in patients underwent temporalis transposition surgery, the difference was statistically significant (χ2=22.415, P<0.05);(3) hard to open eyes:there was 56% in patients underwent nylon thread correction surgery, 55% in patients underwent tarsorrhaphy, 22% in patients underwent temporalis transposition surgery, the difference was statistically significant (χ2=8.795, P<0.05);(4) infections:there was 84% in patients underwent nylon thread correction surgery, 3% in patients underwent tarsorrhaphy, 11% in patients underwent temporalis transposition surgery, the difference was statistically significant (χ2=60.858, P<0.05).CONCLUSION:There are certain clinical efficacy for lagophthalmos caused by leprosy after surgery, especially patients after temporalis transposition surgery can close eyes by oneself.And their vision does not change significantly, which suggests that this surgery may prevent exposure injury for cornea.But the iatrogenic injury, the vision decrease in patients underwent other surgeries and the ocular tissue damage, such as epiphora, lacrimal duct injury, hard to open eyes, infection at the inner and lateral canthus and scar formation of lacrimal apparatus should be pay more attention to.

Objective To determine clinical characteristics and the effects of drug-eluting stents on the occurrence of major adverse cardiac events during percuteneous coronary artery interventional(PCI)and long- term outcomes in patients with chronic renal insufficiency(CRI).Methods Nine hundreds and seventy three patients with angiographically-documented coronary artery disease(lumen inner diameter narrowing＞50%), included 516 patients complicated with experienced renal impairment(CRI group)and 457 with normal renal function(control group).Baseline clinical data and coronary angiographic features were recorded.Results Comparing with control group,patients in CRI group were older with higher incidence of hypertension or diabetes and simultaneously complicated by reduced left ventricular ejection fraction,and more complex coronary lesions(type C).During follow-up(mean 17 months),the mortality was significantly higher in CRI than in control group(6.2% vs 3.3%,P＜0.05),but the former with CRI was significantly lower by using drug-eluting stents in comparing with bare-metal stents(4.1% vs 8.5%,P＜0.05).Conclusion Patients with CRI often complicated with severe coronary artery disease,the mortality after PCI would be significantly reduced by using drug-eluting stents.

To set standards for histomorphological studies on Lysimachia fortunei, an efficacious and widely applied folk medicine in this study, in order to develop its resources. Its species were identified by observing plant morphology and herbs appearance characters, preparing slices with routine methods and defining structural characters. According to the results of morphologic observation, leaves, stamen and pistil of this plant were different from the descriptions in Flora of China.
