Macular diseases usually lead to central vision loss, accompanied by a significant unstable fixation, resulting in disorders of fine vision, reading, and even face recognition, which seriously affect the quality of life of patients.There is no clear and effective treatment to reverse the visual impairment caused by atrophic macular diseases, yet patients with central vision loss secondary to macular diseases commonly adopt a region outside the central macular area as the surrogate fovea for vision, which is named preferred retinal locus (PRL).However, natural PRLs are not optimal in common for low-vision rehabilitation.Therefore, some patients need eccentric fixation training for PRL relocation to achieve better visual rehabilitation.Studies have shown that eccentric fixation training based on biofeedback can stabilize the natural PRL or induce a new PRL to improve low-vision rehabilitation in patients with macular diseases.So far, the development and location characteristics of PRL and the clinical applications and efficacy of training remain controversial.This review concludes the concept and features of PRL, including the characteristics and possible rationale of PRL development, the location and relocation of PRL, and the evaluation indicators of PRL relocation.Furthermore, in order to provide clinical guidance for low-vision rehabilitation of patients with central vision loss, the programs and efficacy of eccentric fixation training for low-vision rehabilitation are also reviewed.

Objective:To compare the outcomes of percutaneous transhepatic one-step biliary fistulation (PTOBF) lithotripsy for type Ⅱa hepatolithiasis performed via the left or right lobe.Methods:A retrospective study was conducted on 79 patients with type Ⅱa hepatolithiasis treated in the First Affiliated Hospital of Guangzhou Medical University from January 2018 to December 2020, including 38 males and 41 females, aged (52.9±14.0) years. All patients had received PTOBF lithotripsy in single channel and divided into left lobe group ( n=40) and right lobe group ( n=39) according to different puncture approaches. Clinical data in immediate and final stone clearance rate, operation time of lithotripsy, intraoperative blood loss, postoperative complications (ascites, biliary tract infection), postoperative hospitalization time, reactive pleural effusion rate, the number of lithotripsy procedures and target bile duct dilatation diameter were compared between the two groups. Results:Compared with left lobe group, right lobe group had higher immediate stone clearance [51.3%(20/39) vs 22.5%(9/40)], less lithotripsy procedures [(2.4±1.0) vs (1.9±1.0)], but had longer postoperative hospitalization time [5(3, 6)d vs 3(2, 6)d] and higher reactive pleural effusion rate [23.1%(9/39) vs 2.5%(1/40)], the differences were all statistically significant (all P<0.05). No significant difference was found in target bile duct dilatation diameter, final stone clearance rate, intraoperative blood loss, postoperative complication rate, and operation time of lithotripsy (all P>0.05). Conclusions:Compared to the left lobe approach, right lobe approach could be prioritized in PTOBF lithotripsy for type Ⅱa hepatolithiasis, considering its higher immediate stone clearance and less lithotripsy procedures, but this surgical approach should pay attention to the occurrence of reactive pleural effusion.

Objective To investigate the effect of glycine N-methyl transferase (GNMT)on intrauterine adhesion (IUA)fibrosis and its related mechanism.Methods In vivo experiment:A total of 36 healthy female SD rats (SPF grade,6～8 weeks old and weighing from 180～220 g)were subjected in this study.IUA model of SD rats and IUA model of GNMT overexpressed rats were established.RT-qPCR and immunofluorescence assay were applied to detect GNMT expression level in normal uterus and model group.RT-qPCR and Western blotting were used to detect the mRNA and protein levels of fibrosis-related molecules and the activation of TGF-β1/Smad3 signaling pathway in each group.The number of endometrial glands in each group was observed by HE staining.Masson staining was used to analyze the severity of endometrial fibrosis in each group.In vitro experiment:transformed human endometrial stromal cells (THESCs)fibrotic phenotype model was constructed using TGF-β1,and THESCs stably transfected with GNMT overexpression lentvirus were treated with TGF-β1.RT-qPCR and Western blotting were used to detect the mRNA and protein expression of fibrosis-related molecules.The expression of TGF-β1/Smad3 signaling pathway was detected by Western blotting.TGF-β1/Smad3 signaling pathway was activated by TGF-β1/Smad signaling pathway activator (SRI-011381),and the expression of TGF-β1/Smad3 signaling pathway and key molecular proteins of fibrosis phenotype was measured with Western blotting.Results In vivo experiment,the mRNA and protein expression levels of GNMT were significantly decreased in the IUA rats than the control rats (P<0.05).Overexpression of GNMT decreased the mRNA and protein levels of fibrosis related molecules,Collagen Ⅰ,Collagen Ⅲ and FN in the IUA rats (P<0.05),and decreased the phosphorylation levels of TGF-β1 and its downstream Smad3 protein (P<0.05).HE and Masson staining showed that overexpression of GNMT could increase the number of endometrial glands and reduce the severity of fibrosis in the IUA rats (P<0.05).In vitro experiments:overexpression of GNMT decreased the mRNA and protein levels of Collagen Ⅰ,Collagen Ⅲ and FN associated with fibrotic phenotype of THESCs (P<0.05),and reduced the phosphorylation level of Smad3 protein,downstream of TGF-β1 (P<0.05).After activation of TGF-β1/Smad3 signaling pathway,the protein levels of TGF-β1/Smad3 signaling pathway and downstream fibrosis phenotype molecules,Collagen Ⅲ and FN,were significantly decreased in the LV-GNMT+SRI-011381 group.Conclusion Overexpression of GNMT can inhibit endometrial fibrosis by regulating TGF-β1/Smad3 signaling pathway,thus achieving therapeutic effect on IUA.

Background Blue light, as an occupational hazard, is widely present in welding and related work environments. However, China's occupational health standard system has not yet established any limit for blue light exposure in welding work environments. Objective To study and propose blue light exposure limits in welding operation environments, and provide a reference for evaluation of blue light hazard and maximum allowable exposure time in welding operations. Methods A function between retinal irradiance and welding arc radiance was introduced by studying arc light and blue light radiation generated in welding operation environments, analyzing the incoherent light radiation protection guidelines issued by the International Commission on Non-Ionizing Radiation Protection (ICNIRP), and combined with factors such as the size of arc light in welding operations, the distance between the welder's eyes and the arc light, and the diameter of the human eye pupil, as well as the geometric optics principle of human eye imaging and the conservation of energy. Then, the radiance limit (100 W·m⁻²·Sr⁻¹) issued by ICNIRP was input into the above function to calculate the blue light irradiance exposure limit in the welding operation environments. Results The blue light irradiance exposure limit in the welding operation environments (\begin{document}$ {E}_{{\rm{B}}}^{{\rm{EL}}} $\end{document}) was 3 W·m⁻². Considering the high repeatability of welding operations, the exposure limit for blue light radiant exposure (\begin{document}$ {H}_{{\rm{B}}}^{{\rm{EL}}} $\end{document}) was 60 J·m⁻². According to the definitions of radiant exposure and irradiance, the maximum allowable exposure time within one working day was calculated according to the formula \begin{document}$ {t}_{\mathrm{m}\mathrm{a}\mathrm{x}}={H}_{{\rm{B}}}^{{\rm{EL}}}{/E}_{{\rm{B}}} $\end{document}, in which \begin{document}$ {E}_{{\rm{B}}} $\end{document} was the measured blue light irradiance in a welding environment. Conclusion Exposure limits of radiant exposure for blue light are proposed to provide important references for evaluating the hazards and maximum allowable exposure time of blue light in welding operations, and for future development of occupational exposure limit standards for blue light in China.

Objective: To analyze the current situation, influencing factors and mechanism of knowledge-attitude-practice(KAP) regarding acquired immune deficiency syndrome(AIDS)/sexually transmitted diseases(STDs) among migrant workers in Chengdu's main urban area, so as to provide a basis for the development of effective prevention and control policies for this group. Methods: Convenience sampling and systematic sampling were used to collect demographic information and data on knowledge, attitudes, and sexual behavior characteristics of AIDS/STDs of the participants. The collected data were organized and statistically analyzed by EpiData 3.1 and SPSS 26.0 software. Additionally, a KAP path analysis model was constructed by using AMOS 24.0 software. Results: A total of 257 valid questionnaires were obtained. The AIDS awareness rate was 55.6%, with a mean scores of(5.59±1.61). The awareness rate of STDs was 37.4%, with a mean scores of(9.05±3.00). Discrimination attitudes towards AIDS and STDs were reported by 58 participants(22.6%) and 44 participants(17.1%) respectively. The prevalence of high-risk sexual behavior was 3.50%. Men(OR=0.500, 95%CI: 0.279-0.897) acted as deterrents to knowledge of AIDS. On the other hand, childlessness facilitated discrimination against AIDS(OR=2.748, 95%CI: 1.385-5.451) and STDs(OR=2.287, 95%CI: 1.084-4.825). There was lower likelihood of engaging in high-risk sexual behavior among migrant workers in Chengdu's main urban area who were older(OR=0.854, 95%CI: 0.785-0.929). The occurrence of high-risk sexual behaviors was influenced both directly and indirectly by attitudes towards AIDS and related knowledge. There was a positive correlation between knowledge about AIDS and STDs and attitudes towards them(r=0.15,0.24, bothP<0.05), as well as between attitudes towards AIDS and attitudes towards STDs(r=0.57,P<0.05). That is, the higher the scores of knowledge, the less likely one was to hold discrimination attitudes. Therefore, increasing the rate of knowledge awareness could reduce discrimination towards AIDS/STDs and the occurrence of high-risk sexual behaviors. Conclusion The level of AIDS/STDs knowledge among the migrant workers in Chengdu′s main urban area is concerning. Innovative interventions should be intensified in key areas and populations.
