Objective To investigate the incidence and the risk factors of anxiety or depression and in the first degree relatives (FDRs) of patients with type 2 diabetes mellitus ( T2DM ). Methods A total of 102 T2DM patients who visited our hospital from May to July 2010 and their FDRs completed SAS,SDS,and life satisfaction evaluation. The medical history of T2DM patients was collected and compared with their FDRs with or without mental disorders. The correlations of risk factors with anxiety or depression were analyzed, t test or X2 test were used for statistical analysis and a P value less than 0. 05 was considered statistically significant. Results The incidence of anxiety or depression of FDRs was 31.4% and 17.6%,respectively. The life satisfaction score of FDRs with mental disorders was significantly decreased ( t = 4. 26 and 4. 09, P＜0. 05 ). Fasting glucose level of T2DM patients with anxious or depressive FDRs was significantly increased ( t = -2. 48 and -2. 15, P＜0. 05 ). Higher medical cost and multiple treatment strategies were positively correlated with SAS and SDS score of the FDRs. Conclusion Higher incidence of mental disorders and lower satisfaction scores could be found in the FDRs of T2DM patients. Better control of blood glucose and reduced treatment cost and strategies may be useful in improving metal condition and life satisfaction of the FDRs of T2DM patients.

Background In recent years,incidence of drug-induced keratopathy is increasing highly.Druginduced keratopathy is lack of typical clinical features and offen confused with the primary disease.Therefore,summarizing and concluding the clinicals feature and standard treatments of drug-induced keratopathy are key problem need to be solved urgently for us.Objective This study was to retrospectively analyze the clinical features and therapeutic procedure of drug-induced keratopathy.Methods A retrospective case series analysis method was adopted.The clinical data of 36 eyes (31 patients) with drug-induced keratopathy were collected by Shandong Eye Hospital from 2008 to 2012,including eye disease history,medication history,medication dosage and duration.A series of relevant examinations were performed,including best corrected visual acuity (BCVA) before and 1 month after treatment,Schirmer test Ⅰ (S Ⅰ t),tear film break-up time (BUT),meibomian gland findings,the location of the keratopathy,the characteristics of keratophthy before and after fluorescein staining.The treating were given,including cessating of the original drugs,applying corneal repair promotion and anti-inflammatory drugs as well as the comprehensive treatment for meibomian gland embolization and dry eye,such as the hot packs and massage in the eyes with meibomian gland dysfunction and a tear dot embolization therapy in the eyes with S Ⅰ t ＜ 5 mm and BUT＜5 s.Paired t test and repeated measured one-way analysis of variance in SPSS 17.0 software were used to compare the BCVA,BUT and S Ⅰ t outcomes.The correlation between corneal repair duration and S Ⅰ t results was analyzed by Pearson linear correlation analysis.Results The primary cause of drug-induced keratopathy was irrational use of drugs,including antiviral drugs,antibiotics,hormone,antiallergic,lowering-intraocular pressure drugs,turn for 23 eyes,12 eyes,10 eyes,1 eye and 1 eye,respectively.Improper route of administration included 25 cases of overuse of eye drops and 6 cases of subconjunctival injection.BCVA was 0.69 ± 0.28 1 month after treatment,which was significantly improved in comparison with before treatment (0.32 ± 0.26) (t =11.02,P ＜ 0.01).Clinical manifestations included corneal epithelial diffusive and point-like roughness,corneal epithelial defect and even corneal ulcer for severe cases,corneal edema,Descemet membrane folds and partially visible corneal filiform.Drug-induced keratophthy was mainly located in the central and lower cornea.Comprehensive therapy was effective with the treating duration about 1 week to 8 weeks.A negative correlation was found between the corneal restore duration and S Ⅰ t results (r =-0.835,P＜0.01).Conclusions Corneal changes secondary to topical medications may affect all layers of the cornea.Clinicians should be mindful of drug-induced ocular disorders.The early diagnosis of druginduced keratopahthy depends on the medical history and clinical features.A comprehensive treating based on ocular surface conditions is available.

Background:CXC chemokine receptor type 2(CXCR2)is a member of G protein coupled receptor superfamily,and is mainly involved in the growth of tumor,angiogenesis and the pathogenesis of inflammatory diseases. Studies showed that CXCR2 was associated with the pathogenesis of inflammatory bowel disease(IBD),but the exact role has not yet been clarified. It was found that the interaction of interleukin-8(IL-8)with CXCR1 and CXCR2 played an important role in the pathogenesis of IBD. Aims:To investigate the expressions and significance of CXCR2 and IL-8 in patients with IBD. Methods:A total of 121 IBD patients in active stage from October 2013 to December 2014 at Zhongnan Hospital of Wuhan University were enrolled and assigned into Crohn’s disease(CD)group and ulcerative colitis(UC)group. Seventy healthy subjects were served as controls(HC). Expressions of IL-8 mRNA and CXCR2 mRNA in peripheral blood and intestinal mucosal tissue were determined by real-time PCR;expression of CXCR2 protein in intestinal mucosal tissue was determined by Western blotting. Results:In peripheral blood,expression of IL-8 mRNA in UC group was significantly higher than that in HC group(P = 0. 017),while expressions of CXCR2 mRNA in CD,UC and HC groups were not significantly different (P = 0. 285). In intestinal mucosal tissue,expressions of IL-8 mRNA in CD,UC and HC groups showed no significant difference(P = 0. 206),while expressions of CXCR2 mRNA in CD and UC groups were significantly higher than that in HC group(P = 0. 002;P < 0. 001),and expression of CXCR2 mRNA in UC group was significantly higher than that in CD group(P = 0. 005);expressions of CXCR2 protein in UC and CD groups were higher than that in HC group(P = 0. 049 P =0. 080). Conclusions:Expressions of CXCR2 mRNA and protein in intestinal mucosal tissue of patients with IBD, especially UC are significantly increased. Down regulation of CXCR2 expression in intestinal mucosa may provide a new target for treatment of UC. IL-8 is significantly highly expressed in peripheral blood of patients with UC,which suggests that IL-8 might be related mainly with UC.

Objective To provide evidence for diagnosis and treatment by investigating the pathogens and drug resistance of immunocompromised host (ICH)pneumonias.Methods Statistical method was used to analyze retrospectively the data of pathogens and drug resistance of ICH pneumonia treated in our hospital in 2014. Results We confirmed 187 cases of ICH pneumonia by pathogen study of 324 patients.Gram-negative bacillus (68.42%)was the main pathogen of ICH pneumonia.Acinetobacter baumanii (AB)accounted for the first place. Staphylococcus aureus infection was still the first of Gram-positive coccus.Conclusion Gram-negative bacillus was the main pathogen of ICH pneumonia in our hospital and the isolated bacteria show strong antibiotic resistance. Therefore,it is necessary to strengthen dynamic monitoring of pathogens in the secretions from ICH pneumonia patients’ lower respiratory tract and drug resistance.It is suggested that clinicians make anti-infection treatment cover drug-resistant bacteria.

Objective To create a MIN6 cell line overexpressing murine Reg3? cDNA and to investigate its cell viability character under low glucose concentrations.Methods The full-length murine Reg3? cDNA was inserted into the plasmid pcDNA3.1(-).Then MIN6 cells were transfected with the Reg3?-pcDNA3.1 and pcDNA3.1 vector alone to establish Reg3?-overexpression and empty vector MIN6 cell line.Reg3? protein in the low glucose concentration cell medium was detected by Western blot.Cell viability was evaluated by an MTT reduction conversion assay.Results Three Reg3?-overexpression MIN6 cells were confirmed by real-time PCR and Western blot.Reg3? expression was barely detectable in the cells transfected with the empty vector alone.In contrast,the levels of Reg3? mRNA and protein in three pcDNA-Reg3?-transfected clones were increased by an average 10-and 6-fold,respectively.Western blot also revealed Reg3? protein release into the culture medium.In MTT cell proliferation assay,compared to vector-transfection alone,three clones of Reg3?-overexpression MIN6 cells exhibited 2-fold increases in cell number over 7 days when cultured in the presence of 10 mL/L fetal bovine serum and 5.5 mmol/L glucose.Conclusion The Reg3?-overexpression MIN6 cells have been established.Reg3? protein was detectable in culture medium,supporting an endocrine action,and Reg3? overexpression promoted islet cell growth.

Background Pupil atresia increases the difficulty of cataract surgery.The improper enlarging pupil will lead to many complications.The appropriate method of pupil dilation is very important to improve the postoperative effect.Objective This study was to evaluate the pupillary function after manually enlarged pupil to different sizes for pupil atresia complicated cataract.Methods A retrospective case-controlled study was designed.Thirty-eight eyes of 30 cases suffered from pupil atresia complicated cataract induced by chronic uveitis were enrolled in Shandong Eye Institute from May 2006 to May 2012.The eyes underwent pupil forming and phacoemulsification and assigned to the pupil enlarged to ≥6.0 mm group (15 eyes) and 4.5-5.5 mm group (23 eyes).The fibrosis membrane at pupil zone was removed,and the fibrosis strip at pupil collar was cut evenly by 23G intraocular microscissors as zigzag shape.Then the pupil was enlarged in multipoint by a pair of left and right iris hook from the main and lateral incisions.The pupils of 15 eyes in the pupil enlarged to ≥6.0 mm group were dilated above 6.0 mm and 23 pupils in the 4.5-5.5 mm group were dilated to 4.5-5.5 mm and followed by routine phacoemulsification and foldable intraocular lens implantation.Topical and systemic corticosteroids and nonsteroidal anti-inflammatory drugs combined topical mydriatic were applied before and after operation.The pupil diameter,light reflex and photophobia symptom in postoperation were compared between the two groups.The visual acuity before and after operation and intra-and post-operative complications were recorded.This study was approved by Ethic Committee of Shandong Eye Hospital,and written informed consent was obtined from each patient before operation.Results The pupil diameter in the pupil enlarged to ≥6.0 mm group was dilated to (6.9±0.4) mm and that of the 4.5-5.5 mm was dilated to (5.1 ±0.3) mm intraoperatively,with a statistical significance between them (t =16.100,P =0.000).Three months later,the pupil diameter in the pupil enlarged to ≥ 6.0 mm group was (4.9 ±0.4)mm,with different degrees of lacerated pupillary margins,and that in the pupil enlarged to 4.5-5.5 mm group was (3.5 ±0.5) mm,with rare lacerated pupillary margins,showing a statistically significant difference (t =9.820,P =0.000).The unresponsive or obtuse light reflex in the pupil enlarged to ≥6.0 mm group was significantly higher than in the pupil enlarged to 4.5-5.5 mm group(11 eyes vs.6 eyes) (x2 =8.200,P =0.005).The subjective photophobia symptom of 2-3 grades in the pupil enlarged to ≥6.0 mm group was in 12 eyes,which was higher than that in the pupil enlarged to 4.5-5.5 mm group (2 eyes) (H=19.840,P=0.000).The iris haemorrhage were seen in 3 eyes in the pupil enlarged to 4.5-5.5 mm group and 7 eyes in the pupil enlarged to ≥6.0 mm group (x2 =5.290,P=0.030).The visual acuities of the operated eyes in the two groups improved at different degrees.Conclusions Approximate physiological pupil and good visual quality can been obtained by manual releasing and enlarging pupil to less than 5.5 mm evenly during the surgery for pupil atresia complicated cataract induced by chronic uveitis.

Background Eyes with filamentary keratitis present with serious clinical symptoms.This disease is easy to relapse and the treatment is tricky.At present,its pathogenesis is still unclear,and few works were done on filamentous composition.Objective This study was to analyze the composition of corneal filament by imageological and histopathological method,and discuss the formation mechanism of filamentary keratitis.Methods Eighty-eight eyes of 82 cases who suffered from filamentary keratitis were collected in Shandong Eye Hospital between January 2008 and January 2011.The etiologies of the patients were classified and the clinical data were recorded.Firstly,the corneal filiform strip was detected by laser scanning confocal microscopy (LSCM),and the corneal structure was examined by high-definition optical coherence tomography (HD-OCT).Then the composition of filamentary strip was analyzed by Giemsa and Masson trichrome staining of stretched preparation of filiform strip.Results Etiological study showed that filamentary keratitis occurred after penetrating keratoplasty in 40 eyes,after cataract surgery and photorefractive keratectomy (PRK) in 18 eyes,dry eye and neural dystrophic corneal disease in 14 eyes,acute conjunctivitis in 10 eyes.HD-OCT revealed that filament lesion developed to Bowman layer.Filament was composed of epithelial cells,inflammatory cells,mucus and the high reflective strip core with spiral arrangement under the LSCM,and epithelial cells,inflammatory cells and fibrous tissue were seen in the strip core.Giemsa staining exhibited that filament contained corneal epithelial cells,inflammatory cells,mucus and dark blued strip core with helical arrangement.Masson trichrome discovered that the strip core was red fibrous tissue surrounding by blue mucus.Conclusions Epithelial cells,inflammatory cells,mucus and the high reflective strip core with spiral arrangement are the main elements of filament in filamentary keratitis.The lesion can reach Bowman layer.The results contribute to reveal the formation mechanism of corneal filament and assist treatment.

The contribution of particles to cardiovascular mortality and morbidity has been enlightened by epidemiologic and experimental studies. However, adverse biological effects of the particles with different sizes on cardiovascular cells have not been well recognized. In this study, sub-cultured human umbilical vein endothelial cells (HUVECs) were exposed to increasing concentrations of pure quartz particles (DQ) of three sizes (DQPM1, <1 μm; DQPM3-5, 3-5 μm; DQPM5, 5 μm) and carbon black particles of two sizes (CB0.1, <0.1 μm; CB1, <1 μm) for 24 h. Cytotoxicity was estimated by measuring the activity of lactate dehydrogenase (LDH) and cell viability. Nitric oxide (NO) generation and cytokines (TNF-α and IL-1β) releases were analyzed by using NO assay and enzyme-linked immunoabsorbent assay (ELISA), respectively. It was found that both particles induced adverse biological effects on HUVECs in a dose-dependent manner. The size of particle directly influenced the biological activity. For quartz, the smaller particles induced stronger cytotoxicity and higher levels of cytokine responses than those particles of big size. For carbon black particles, CB0.1 was more capable of inducing adverse responses on HUVECs than CB1 only at lower particle concentrations, in contrast to those at higher concentrations. Meanwhile, our data also revealed that quartz particles performed stronger cell damage and produced higher levels of TNF-α than carbon black particles, even if particles size was similar. In conclusion, particle size as well as particle composition should be both considered in assessing vascular endothelial cells injury and inflammation responses induced by particles.
