Background The incidence of dry eye is increasing among young adults because of wide usage of video display terminal.But the early diagnosis of dry eye still presents challenge to medical practitioners.The accurate diagnosis and treatment of the dry eye,therefore,is a topic of high interest to researchers.Previous examination outcome of dry eye is interferred primarily due to invasive procedure.It is very important to search an examination approach.Objective This study was to use Keratograph 5M,a non-invasive ocular surface analyzer to evaluate the influence of watching video display terminal on ocular surface and tear film.Methods Eighty-one eyes of 81 health volunteers among 18-30 years were enrolled in Affiliated Eye Hospital of Nanchang University from March 1,2015 to November 10,2015 under the informed consent,including 39 males and 42 females.The subjects watched the computer for continuously 3 hours under the nature light,and ocular surface related examinations were performed and compared before and after video display terminal exposure,including non-invasive tear film break-up time (NITBUT),tear meniscus height,conjunctival hyperemia scoring,limbal congestion scoring,corneal fluorescein staining scoring,meibomian gland imaging and lipid layer analysis.Results The number of eyes with visual fatigue,dryness,pain,blurring and conjunctival congestion was significantly increased after 3-hour video display terminal exposure in comparison with before (all at P＜0.01).The initial NITBUT and mean NITBUT were (6.086± 3.701) s and (9.103 ± 4.680) s,and tear meniscus height was (0.190 ± 0.032) mm after trail,which were significantly lower than (11.445 ±4.964) s,(14.626 ±4.467) s and (0.212 ±0.040) mm of before trail,respectively;The conjunctical hyperemia scoring and limbal congestion scoring were 0.869 ±0.311 and 0.572 ±0.276 after trial,which were significantly higher than 0.780 ± 0.306 and 0.509 ± 0.266 before trail,showing significant differences before and after exposure of video display terminal (all at P＜0.01).The intraocular pressure and the eye number of different scores of corneal fluorescence staining,abnormal meibomian gland and different morphological lipid layer of tear were unchanged before and after exposure of video display terminal.Conclusions Long-term exposure of video display terminal results in significant and temporary adverse influence on tear film and ocular surface.Keratograph 5M non-invasive ocular sudace analyzer can objectively assess overall ocular surface conditions.

Endoscopic activity has been used as an endpoint in treatment of Crohn's disease (CD).Simplified Endoscopic Score for Crohn's Disease (SES-CD) is a simple and easy-to-use endoscopic scoring system for CD, however, studies evaluating the correlation between SES-CD and noninvasive inflammatory markers are scarce.Aims: To investigate the correlation between SES-CD and clinical and laboratory inflammatory markers for identifying a noninvasive surrogate marker for endoscopic activity of CD.Methods: Forty-two patients with CD were enrolled for detecting laboratory inflammatory markers including leukocyte and platelet count, C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), hemoglobin (Hb), albumin (Alb) and fecal calprotectin (FC);SES-CD and Crohn' disease activity index (CDAI) were assessed.Predictive performance of these markers for endoscopic activity of CD was analyzed by ROC curve, and the correlation of SES-CD with all these markers was evaluated.Results: The platelet count, CRP, ESR, FC and SES-CD were significantly higher in active CD than in inactive CD, while Hb and Alb were significantly lower in active CD (P all <0.05).In all the noninvasive markers, only CDAI and FC had an area under the curve (AUC) greater than 0.9 for predicting CD endoscopic activity.Taken 150 as the cut-off value of CDAI and 50 μg/g (the upper limit of normal, ULN) as the cut-off value of FC, the sensitivity of CDAI and FC were 58.8% and 100%, and the specificity were 100% and 60.0%, respectively.SES-CD had moderate correlation with CDAI, platelet count, CRP, ESR, Alb and FC, respectively (P all <0.05).Conclusions: SES-CD is correlated moderately with the clinical and laboratory inflammatory markers, however, when taken the ULN as cut-off value the conventional inflammatory markers such as CDAI, CRP and ESR are hard to predict sensitively and accurately the endoscopic activity of CD;while FC has fairly high accuracy and sensitivity and can be used as a noninvasive surrogate marker for evaluating endoscopic activity of CD.

Background:Abnormal immune response is involved in the pathogenesis of Crohn’s disease( CD),and T lymphocytes are the main players in the immune response. Aims:To investigate the relationship between peripheral blood CD3 + ,CD4 + and CD8 + T cells and inflammation-related markers in patients with CD. Methods:Proportions of peripheral blood CD3 + ,CD4 + and CD8 + T cells were measured by flow cytometry in 26 CD patients( including 14 patients in active stage and 12 in remission stage )and 8 healthy volunteers(control group),and their correlation with inflammation-related markers(including white blood cell count,platelet count,ESR,CRP,albumin and hemoglobin) were analyzed. Results:Proportions of CD3 + ,CD4 + and CD8 + T cells were significantly increased in patients with active CD than those with remission CD and controls( P ﹤ 0. 05),however,no significant differences were found between remission CD patients and controls(P ﹥ 0. 05). ESR and CRP in active CD patients were significantly higher than those in controls(P ﹤ 0. 05),while albumin and hemoglobin levels were significantly decreased(P ﹤ 0. 05);albumin in remission CD patients was significantly lower than that in controls(P ﹤ 0. 05). No significant differences in white blood cell count and platelet count were found between active,remission CD patients and controls(P ﹥ 0. 05). Proportions of CD3 + , CD4 + and CD8 + T cells were positively correlated with CRP,and negatively correlated with hemoglobin( P ﹤ 0. 05);CD3 + and CD4 + T cells were positively correlated with ESR(P ﹤ 0. 05). However,CD3 + ,CD4 + and CD8 + T cells were not correlated with white blood cell count,platelet count and albumin level( P ﹥ 0. 05). Conclusions:Proportions of peripheral blood CD3 + ,CD4 + and CD8 + T cells are increased with the increase of disease activity in CD,and are positively correlated with CRP,and negatively correlated with hemoglobin.

Ponseti clubfoot treatment has become more popular during the last decade because of its high initial correction rate. But the most common problem affecting the long-term successful outcome is relapse of the deformity. Non-compliance with Ponseti brace protocol is a major problem associated with relapse. Although more comfortable braces have been reported to improve the compliance, they all have the same design and no significant changes have been made to the protocols. After refinement in the Ponseti method and emphasizing the importance of brace to parents, the relapse rate has been markedly decreased. Nevertheless, there are patients who do not have any recurrence although they are not completely compliant with the brace treatment, whereas other patients have a recurrence even though they are strictly compliant with the brace treatment. The aim of this article is to review the relapse of clubfoot and the function of the brace and to develop an individualized brace protocol for each patient by analyzing the mechanism of the brace and the biomechanical properties of muscles, tendons, and ligaments.

Objective:To explore the gene mutations of UGT1A1 * 6 and UGT1A1 * 28 in patients with unconjugated hyperbilirubinemia after renal transplantation and understand their clinical significance.Methods:UGT1A1*6 and UGT1A1*28 gene fragments in blood samples of patients with unconjugated hyperbilirubinemia after renal transplantation were detected by digital fluorescent molecular hybridization sequencing.Results:A total of 21 patients with unconjugated hyperbilirubinemia after renal transplantation were examined for UGT1A1*6 and UGT1A1*28 alleles. The results showed that there were 3 UGT1A1*28 and UGT1A1*6 combined heterozygous mutations, 4 UGT1A1*28 gene heterozygous mutations, 2 UGT1A1*6 heterozygous mutations and 4 UGT1A1*6 homozygous mutations. Among them, the mutation rates of UGT1A1*28 gene and UGT1A1*6 gene were 33%(7/21) and 43%(9/21) respectively and the total mutation rate of both was 62%(13/21).Conclusions:UGT1A1 polymorphism is associated with unconjugated hyperbilirubinemiaafter renal transplantation. By detecting the sequence of UGT1A1*6 and UGT1A1*28 gene fragments in blood samples of renal transplant patients, it is helpful to clarify the etiology of unconjugated hyperbilirubinemia after renal transplantation to confirm the diagnosis of Gilbert syndrome and rule out the effect of immunosuppressive drugs on liver function so as to guide the clinical medication of renal transplant patients.

Objective:To investigate the pathogenesis, selection of endovascular treatment (EVT) strategies, and efficacies of acute vertebrobasilar artery occlusion (AVBAO) of different lesion sites.Methods:One hundred and five patients with AVBAO, admitted to and accepted EVT in our hospital from February 2017 to September 2019, were chosen in our study. The data of disease onset, imaging findings, EVT status, perioperative complications, and prognoses of these patients were collected. According to DSA results, the involved lesions were divided into 4 sites: the upper segment of basilar artery (BA), the middle segment of BA, the lower segment of BA, and the intracranial segment of vertebral artery (V4 segment), and patients with tandem lesions would be recorded as distal lesions. The risk factors, EVT strategies, and prognoses 90 d after follow-up (modified Rankin scale [mRS] scores≤3: good prognosis) were compared in patients with 4 different lesion sites.Results:There were significant differences in etiological classifications and percentage of patients combined with atrial fibrillation among patients with 4 different lesion sites ( P<0.05). There was significant difference in proportion of patients accepted emergency stent implantation among patients with 4 different lesion sites ( P<0.05): those with lesions at the V4 segment had the highest proportion of patients accepted emergency stent implantation (79.55%), followed by those with lesions at the lower segment of BA (50.00%). There was significant difference in EVT time (the time from arterial puncture to successful recanalization of occluded vessels) among patients with 4 different lesion sites ( P<0.05): the EVT time in patients with lesions at the middle segment of BA was the shortest (87.5 [58.5, 130.8] min), and the EVT time in patients with lesions at the lower segment of BA was the longest (115.0 [81.0, 163.0] min). There was no statistical difference among patients with different lesion sites in good prognosis rate 90 d after follow-up ( P>0.05). Conclusion:The pathogenesis of patients with different AVBAO lesion sites is different, so different EVT strategies should be adopted.

AIM: To investigate the effects of placement of the absorbable packing material Nasopore around the anastomosis site on postoperative re-bleeding, discomfort, and on the success rate of endoscopic dacryocystorhinostomy(En-DCR).METHODS: Prospective randomized controlled study. A total of 101 patients(101 eyes)diagnosed with chronic dacryocystitis that underwent En-DCR in the ophthalmology department, Renmin Hospital, Hubei University of Medicine from November 2020 to October 2021 were collected. The patients were randomly divided into two groups according to whether they were packed with Nasopore at the end of operation, namely, the packed group(49 eyes)and the non-packed group(52 eyes). The postoperative follow-up was 9 mo, the degree of re-bleeding, discomfort, and postoperative success rate(including anatomical success rate and functional success rate)were compared between the two groups of patients.RESULTS: This study included 94 patients, including 45(45 eyes)and 49(49 eyes)in packed group and non-packed group, respectively. The En-DCR was performed successfully in all patients. Postoperative re-bleeding occurred in 1 eye(2%)in the packed group, and 9 eyes(18%)in the non-packed group(P<0.05); postoperative nasal discomfort occurred in 2 cases(4%)in the packed group, and 9 cases(18%)in the non-packed group(P<0.05); The success rate of postoperative anatomical success rate was 93%(42/45)in the packed group and 88%(43/49)in the non-packed group(P>0.05). The postoperative functional success rate was 89%(40/45)in the packed group and 86%(42/49)in the non-packed group(P>0.05). Other complications such as orbital fat prolapse, cerebrospinal fluid leakage, sinusitis, visual impairment and double vision were not observed in all patients during the follow-up.CONCLUSION: Nasal packing absorbable material Nasopore around the anastomosis at the end of En-DCR operation can reduce postoperative re-bleeding and postoperative discomfort of patients, and it has no obvious effect on the postoperative success rate.
