AIM:To observe the changes of Th17 related cytokines in tears of conjunctivochalasis(CCH)patients with liver-kidney yin deficiency treated with traditional Chinese medicine Qi Jing Mingmu decoction combined with artificial tears.METHODS:A total of 56 CCH patients(56 eyes)with liver-kidney yin deficiency of grade Ⅱ to Ⅲ were collected and randomly divided into treatment group(treated with Qi Jing Mingmu decoction combined with artificial tears)of 26 cases(26 eyes)and control group(treated with pure artificial tears)of 30 cases(30 eyes). The treatment course was 1 mo, and international ocular surface disease index(OSDI), tear film break-up time(BUT), tear meniscus height(TMH)and conjunctival congestion index of the patients were observed before and after treatment. The patients' tears were collected before and after treatment, and Th17 related cytokines in tears were detected using flow cytometry immunofluorescence luminescence method.RESULTS:After treatment, the OSDI, BUT and conjunctival congestion index of CCH patients in the treatment group and control group were significantly improved(all P<0.01). After treatment, the TMH of CCH patients in the treatment group was significantly reduced(P<0.01), while there was no statistically significant difference in TMH of the control group before and after treatment(P=0.41). After treatment, the levels of Th17 related cytokines IL-17A, IL-22, IFN-γ, IL-17F, and IL-1β in tears of CCH patients in the treatment group were significantly reduced after treatment(all P<0.01), and the changes in the treatment group were more significant(all P<0.05). There was no significant difference in the control group before and after treatment(all P>0.05). After treatment, the levels of IL-6 and TNF-α in the tears of both groups of CCH patients decreased compared to those before treatment(both P<0.05), but the changes in the treatment group were more significant(both P<0.01).CONCLUSION:Qi Jing Mingmu decoction combined with artificial tears can effectively improve the ocular surface microenvironment, enhance tear film stability, and inhibit ocular surface inflammation in CCH patients with liver-kidney yin deficiency. This may be related to its reduction in the secretion of Th17 related cytokines in tears.

Dry eye is an age-related disease characterized by tear film instability and ocular discomfort.Its onset is closely related to various factors such as age and environment.Studies have shown that oxidative stress plays a key role in the pathogenesis of dry eyes.This review mainly describes the mechanism of oxidative stress by activating autophagy,in-flammation and aging to induce dry eyes,and the application progress of the antioxidants from natural foods in relieving the oxidative stress state of the ocular surface and treating dry eyes.

Cataract is a common eye disease caused by metabolic disorders of the lens, which can lead to visual impairment or blindness. Its occurrence and development are affected by various factors, among which age is the most important factor. At present, drug therapy only has a delaying effect on early cataracts, but surgical treatment is still needed for cataracts that affect vision in the middle and late stages. Therefore, it is crucial to establish an experimental cataract model and explore appropriate drugs for preventing and treating cataracts. D-galactose has been widely used in the study of aging animal models, and is often used in the models of diabetes cataract and age-related cataract. This article elaborates on the pathogenesis, modeling methods, and evaluation criteria for successful modeling of D-galactose-induced cataract models, in order to guide experimental researches related to cataract prevention and treatment.

Objective To study the protective effect of polydatin on lipopolysaccharide-induced injury of human umbilical vein vascular endothelial cells(HUVECs)through the protein Janus kinase 2(JAK2)/signal transducers and activators of transcription 3(STAT3)signaling pathway.Methods HUVECs were cultured in vitro,and 500 ng/ml LPS induced their injury and set as a model group;based on the model group,endothelial cells were inter-vened with different concentrations(10,20,and 40 μmol/L)of polydatin for 24 h,and set as polydatin low concentration group,polydatin medium concentration group,and polydatin high concentration group,respectively;a control group was set as another group.CCK-8,monocyte-endothelial cell adhesion,scratch and Transwell assays were used to detect cell viability,adhesion,migration and invasive ability;ELISA was used to detect interleukin-6(IL-6)and tumor necrosis factor-alpha(TNF-α)levels in the cell supernatant;Western blot was used to detect the expression of proteins related to the JAK2/STAT3 signaling pathway levels of JAK2/STAT3 signaling pathway relat-ed proteins.Results Compared with the control group,the model group showed decreased cell survival(P＜0.01),increased cell adhesion,migration and invasion(P＜0.001,P＜0.05,P＜0.01),increased levels of IL-6 and TNF-α in the cell supernatant(P＜0.001),and increased levels of phosphorylation of JAK2 and STAT3 pro-teins in the cells(P＜0.05).Compared with the model group,LPS damage to cells was attenuated after polydatin intervention,cell survival was increased in polydatin low-,medium-and high-concentration groups(P＜0.05),cell adhesion,migration,and invasion decreased(P＜0.05,P＜0.05,P＜0.001),IL-6 and TNF-α levels in cell supernatants decreased(P＜0.05),and the levels of cellular JAK2 and STAT3 protein phosphorylation lev-els decreased(P＜0.05).Conclusion Polydatin seems to reduce the inflammatory injury of human umbilical vein endothelial cells induced by LPS,reducing the secretion of inflammatory factors,and inhibiting the ability of cell ad-hesion,migration and invasion,which may be related to the down-regulation of JAK2/STAT3 signal pathway by polydatin.

Objective:The problems associated with child health continue to constitute a global concern,and child morbidity and mortality remain problematic in Sub-Sahara Africa(SSA).Utilizing a community-based survey conducted in Ibadan North Local government,Southwest Nigeria the study examined the influences of maternal perceived self-efficacy(MPSE)and maternal perceived vulnerability(MPV)on child health outcomes(CHO).Methods:The study appraised data from 683 nursing mothers aged 15-45 obtained from 20 major primary healthcare centers in the region undergoing routine health checks for their children.Three regression models were fitted to examine the effects of MPV,MPSE,and confounding variables of maternal preventive actions such as insecticide-treated nets(ITN)usage and child immunization,among other maternal and child sociodemographic attributes on CHO.Results:The study finds that MPV has no correlation with CHO and MPSE but positively correlates with maternal age(r=0.123,P＜0.05).However,CHO has a negative correlation with MPSE(r=-0.200,P＜0.05)while positively correlated with child age(r=0.134,P＜0.05).MPSE has a unique effect on CHO(β=-0.203,P＜0.05),maternal preventive action of ITN usage show a positive association with CHO in the study Model 2(β=-0.163,P＜0.05),while in Model 3,child's age has a positive association with CHO(β=0.180,P＜0.05).The net effect of the study models accounted for approximately 10％of the variance in CHO reported among the children.Conclusion:Overall,MPSE and ITN usage are essential factors for understanding and reducing the potential adverse CHO.Global effort must continue to improve maternal education to support child health and preventive care practices in SSA.

Abstract: The loop-mediated isothermal amplification (LAMP) technique is a technique for the specific and efficient amplification of target fragments at a constant temperature using two pairs of specially designed primers and a strand displacement activity DNA polymerase. LAMP technique is a simple, rapid, specific, sensitive and cost-effective nucleic acid amplification method, and therefore has a promising future in the field rapid detection of Mycobacterium tuberculosis and grassroots applications. In this review, the basic principles and characteristics of the LAMP technique, the main molecular markers for the diagnosis of tuberculosis, and the use of different molecular markers and various types of novel techniques in the diagnosis of pulmonary tuberculosis, extrapulmonary tuberculosis, and drug-resistant tuberculosis were described. The LAMP technique has been widely used in the diagnosis of tuberculosis with high sensitivity and specificity, but the technique still has some shortcomings. This paper reviews the progress of its application in tuberculosis in recent years and provides an outlook on its development, with a view to providing a rational research direction for rapid diagnosis of tuberculosis in a resource-limited environment.

Cyclin-dependent kinase 9 (CDK9) activity is correlated with worse outcomes of triple-negative breast cancer (TNBC) patients. The heterodimer between CDK9 with cyclin T1 is essential for maintaining the active state of the kinase and targeting this protein-protein interaction (PPI) may offer promising avenues for selective CDK9 inhibition. Herein, we designed and generated a library of metal complexes bearing the 7-chloro-2-phenylquinoline CˆN ligand and tested their activity against the CDK9-cyclin T1 PPI. Complex 1 bound to CDK9 via an enthalpically-driven binding mode, leading to disruption of the CDK9-cyclin T1 interaction in vitro and in cellulo. Importantly, complex 1 showed promising anti-metastatic activity against TNBC allografts in mice and was comparably active compared to cisplatin. To our knowledge, 1 is the first CDK9-cyclin T1 PPI inhibitor with anti-metastatic activity against TNBC. Complex 1 could serve as a new platform for the future design of more efficacious kinase inhibitors against cancer, including TNBC.

Background: Workplace bullying is defined as frequent, ongoing, and detrimental incidence of unreasonable acts/behaviors directed towards an individual. The consequences of bullying to individuals often lead to absenteeism, resignation, job dissatisfaction, and suicidal ideation making it a major public health concern. This organizational issue, when not addressed, will greatly affect the workflow in any organization. There is a paucity of literature on this problem in the Southeast Asian countries Objective: This study aimed to describe the extent of workplace bullying among employees of a public higher education institution. Methodology: The researchers used a descriptive, cross-sectional study design. Survey questionnaires in Google Form were emailed to all employees with a 35.96% participation rate. The survey instrument asked participants to indicate their awareness about any bullying behavior in their unit and to specify the typical profile of bullies and victims they know of. Responses to quantitative variables were summarized using the mean and standard deviation, while qualitative variables were reported as frequency and percentage distribution. The software used for analysis were Microsoft Excel and EpiInfo 7. Results: At least one-third (36.94%) of survey respondents indicated that they witnessed a form of bullying in the workplace with more awareness seen among faculty members and permanent employees. The most common type of bullying observed in the workplace was criticism in public. Notably, this type of bullying was similar across employee categories. The predominant reactions of victims of bullying include feeling of fear and loss of trust, and confiding to a friend or co-worker. Conclusion The phenomenon of bullying has been witnessed by the employees and reported to have adverse effects on victims. Informational campaigns coupled with anti-bullying policy and programs are necessary to promote employee well-being.
