AIM: To analyze the change of serum inflammatory factors in glaucoma patients at different stages and its clinical significance. ·METHODS:Totally 70 cases of 128 eyes with primary open-angle glaucoma in our hospital from January 2014 to August 2016 were selected. According to the mean defect of visual field, they were divided into light ( observation Group 1 ) , moderate ( observation Group 2 ) and heavy group(observation Group 3). Another 65 cases of 130 eyes with cataract were taken as the control group in our hospital. The observation and expression of serum cytokines in these patients with glaucoma were taken. ·RESULTS:There was no significant difference in serum IL-2 and IFN- γlevels between the two groups (P>0. 05). The sIL-2R and IL-4 levels in the glaucoma group were higher than those in the control group, and the levels of IL-6 and IL-12 were lower than those of the control group (P<0. 05). The IOP and proportion of myopia in the glaucoma group was higher than that in the control group, the difference was not statistically significant ( P<0. 05) . The ratio of moderate myopia to severe myopia in each group was not statistically significant (P>0. 05). To observe the low myopia ratio in Group 3 of patients, it was less than observation Group 1 and observation Group2 ( P > 0. 05 ). There was no statistically significant difference between observation Group 1 and 2 of patients on IL-2, sIL-2R, IL-4, IL-6 and IFN-γlevels (P>0. 05). The level of sIL-2R in the Group 3 was higher than that in the Group 1, and the level of IL-12 was lower than that in the Group 1 and in the Group 2 (P<0. 05). There was no significant difference in IL-2, IL-4, IL-6 and IFN-γlevels between the glaucoma patients (P>0. 05). The IOP level and the proportion of myopia in the Group 3 were higher than those in the Group 1 and the Group 2 were observed, the difference was statistically significant (P<0. 05). The intraocular pressure was higher in Group 2 than in group 1 (P<0. 05). There was no statistically significant difference on proportion of myopia between observation Group 1 and observation Group 2 (P>0. 05). ·CONCLUSION: The levels of serum IL-12, sIL-2R and intraocular pressure in patients with primary open-angle glaucoma fluctuated significantly at different stages of the nerve injury, indicating that the immune response and intraocular pressure were involved in the process of optic nerve damage.

This study investigated the effect of etoposide, an anticancer chemotherapy drug, on B7-H1 expression in retinoblastoma (Rb) cells and the role of miR-513a-5p in the process. Rb cells were divided into control and etoposide groups. In the etoposide group, cells were treated with etoposide at different concentrations (2.5, 5, 10, 20 and 40 μg/mL) for 24 h. Those given no treatment of etopside served as controls. Reverse transcription polymerase chain reaction (RT-PCR), fluorescence quantitative PCR and flow cytometry were performed to measure the mRNA and protein expression of B7-H1 in Rb cells. The mRNA expression of miR-513a-5p in Rb cells before and after etoposide treatment was also detected by fluorescence quantitative PCR. The miR-513a-5p mimics and the miR-513a-5p inhibitor were transfected into Rb cells separately, and fluorescence quantitative PCR and flow cytometry were used to detect the effect of the miR-513a-5p mimics or inhibitor on B7-H1 expression. TargetScan5.2 was employed to predict the miR-513a-5p binding sites in the 3'-untranslated region of B7-H1 mRNA. Luciferase reporter plasmids carrying this site were prepared and transfected into Rb cells and luciferase activity analyzed. The results showed that etoposide stimulated the mRNA and protein expression of B7-H1 in Rb cells, which reached a maximal level after treatment with 5 μg/mL etoposide (P<0.05). However, miR-513a-5p expression was decreased in Rb cells after etoposide treatment. When the miR-513a-5p inhibitor was added, B7-H1 expression was increased with the concentration of the miR-513a-5p inhibitor (P<0.05). Moreover, B7-H1 expression was decreased gradually with the concentration of the miR-513a-5p mimics increased (P<0.01). Additionally, the miR-513a-5p mimics were found to inhibit the luciferase activity. It was concluded that etoposide can promote B7-H1 expression in Rb cells, which may be associated with chemoresistance. The promoting effect of etoposide on B7-H1 expression can be reversed by miR-513a-5p mimics. MiR-513a-5p inhibits the mRNA and protein expression of B7-H1 via binding to the 3'-UTR of B7-H1 mRNA.

Objective:To assess whether familial occurrence has an influence on the morphological characteristics of patients with nonsyndromic cleft lip and/or palate (NsCL/P).Methods:A case-control analysis was performed on the morphological characteristics of familial group and sporadic group,using medical records of 1967 patients with NsCL/P treated in the Affiliated Stomatological Hospital of Nanchang University from 2002 to 2014.Results:164 (8.34％) cases presented a positive history of cleft in their families.The cleft types,the positive familial rate of cleft lip only (CLO),cleft lip and alveolar ridge(CLA),cleft lip and palate (CLP) and cleft palate only (CPO) were 8.11％,8.54％,6.19％ and 9.65％ respectively.A positive family history of NsCL/P was associated with 0.66 times risk of CPO (P =0.036,OR =0.66,95％ CI 0.44-0.98) compared to those of CLO,CLA and CLP.In familial group of CLP,the lateral incidence of male patients was different from that of female patients (P ＜ 0.001).There was no significant difference between familial group and sporadic group on birth weights,parental child-bearing age and clinical manifestations of patients.Conclusion:Familial occurrence might have an influence on cleft type,laterality and gender of the patients with NSCL/P.

ObjectiveTo investigate the epidemic situation of brucellosis in Datong city, and to provide scientific evidence for making appropriate prevention and control measures. MethodsSurveillance data of human brucellosis in 7 countris and 4 districts in Datong city between 2006 and 2009 were collected, throng the national network straight quote system in an infectious diseases. Excel database was established and all data were statistically analyzed. Incidence of brucellosis in local population was analyzed. The regional distribution, time distribution,occupation, age and sex distribution were analyzed. Epidemic characteristics and trend of brucellosis in Datong city were summarized. Results A total of 5195 cases of brucellosis patients in Datong were found between 2006 and 2009, the average incidence rate was 57.51/10 million. All counties had the disease, and the onset of the disease mainly in the spring and summer. Most cases were young males. Farmer case was 81.67％(4243/5195) of the total patients. ConclusionsFrom 2006 to 2009, epidemic characteristic of Datong human brucellosis ishigh-low-high(incidence). We suggests the Department concerned to strengthen the prevention and control of the disease in some counties, focusing on spreading of disease prevention and control knowledge among farmers and increase their self-protection awareness.

Objective To determine if urinary cystatin C (uCys C) level can predict mortality in critically ill neonates.Methods This prospective study included neonates admitted to the intensive care unit within the first 6 hours of life from May.2011 to Oct.2012.Neonates were assigned into survivor and non-survivor groups based on whether they died during the first week of life.The uCys C level was measured on the day of admission.The score for neonatal acute physiology (SNAP) was calculated based on 28 items collected during the first 24 hours of admission.Multivariate Logistic regression analysis was used to determine whether uCys C level was a predictor of mortality.A receiver operating characteristic (ROC) curve was constructed and the area under the ROC curve (AUC) was calculated to assess the predictive strength.Results Of the total 155 neonates,12 cases (7.1％) died during the first week of life.When compared to survivors,the gestational age (t =2.810,P =0.006) and birth weight (t =3.245,P =0.001) in non-survivors were significantly lower; but the uCys C level (z =-3.426,P =0.001),the SNAP score (z =-3.308,P =0.001),and the use of mechanical ventilation (x2 =23.877,P =0.000) were significantly higher.Logistic regression analysis revealed that uCys C remained significantly associated with mortality after adjusting for gestation age,birth weight,or the SNAP score (P =0.024).uCys C achieved AUC of 0.81 (95％ CI:0.71-0.92,P =0.001).When combined with SNAP and mechanical ventilation,the predictive performance of uCys C improved AUC 0.93 (95 ％ CI:0.86-1.00,P =0.000).Conclusion uCys C is significantly associated with adverse outcome of death and independently predictive of mortality in critically ill neonates.

OBJECTIVETo compare the efficacy of two surgical techniques for controllong nasal width after Le Fort I osteotomy.

METHODSFifty-five patients who received the Le Fort I osteotomy have been included in this study. They were randomly divided into 2 groups. The experimental group received extraoral ABS, and the control group received traditional intraoral ABS. 3D photos of the patient's face were taken before operation and at postoperative 3 months. Alar width was measured on the 3D photos. Data was reported as means and standard deviations, and statistic analysis was done by using student t test.

RESULTSCompared with presurgical data, G. lat-G. lat increased by (2.66 +/- 1.47) mm, Al-Al increased by (2.20 +/- 1.22) mm and Sbal-Sbal increased by (1.30 +/- 1.33) mm in experimental group. G. lat-G. lat increased by (1.38 +/- 1.29) mm, Al-Al increased by (1.06 +/- 0.95) mm and Sbal-Sbal increased by (0.36 +/- 1.33) mm in the control group. There was significant difference between two groups.

CONCLUSIONSThe surgical technique of ABS is the most important factor for determining the postoperative alar width. Both techniques have better effect on the Sbal-Sbal width control than the G. lat-G. lat and Al-Al width control. Traditional intraoral ABS can more effectively control the alar width. Both techniques cannot completely control the alar base widening after Le Fort I osteotomy.
