AIM: To assess the effectiveness of selective laser trabeculoplasty(SLT)in the treatment of primary open angle glaucoma(POAG).METHODS:Totally 24 patients(33 eyes)with POAG who had poor control of intraocular pressure(IOP)from June 2022 to December 2023 were included in this retrospective study, and all of them were treated with SLT. Furthermore, the IOP, mean deviation(MD), mean sensitivity(MS), and the thickness and vascular density(VD)of optic disc nerve layer were compared after treatment. RESULTS: There were significant reducion in IOP at 1, 3, 6, 12 mo after treatment(all P<0.001). There were no statistically significant differences in MD and MS before treatment and at 6 and 12 mo after treatment(all P>0.05), and there were no statistical significant differences in the thickness and VD of optic disc(all P>0.05).CONCLUSION: SLT can significantly reduce IOP in POAG patients in the short term, without damaging the visual field and optic disc nerves, while the effectiveness of SLT decreases over time.

Objective: To evaluate the suitability of the existing hemolysis rate standards for locally processed red blood cell components by retrospectively analyzing 5-year hemolysis rate data at the end of storage. Methods: A total of 720 blood samples of three types of red blood cell components from our blood station from January 2019 to December 2023 were collected. Parameters included hemoglobin concentration (Hb), hematocrit (Hct), and free hemoglobin concentration (fHb). Hemolysis rate were taken as the control standard of 0.8% in accordance with the national standard. The hemolysis rates were compared against the national standard threshold of 0.8% (GB18469-2012), and annual trends of the detection parameters were observed. Results: The hemolysis rates (x-+s,%) of leukocyte-depleted whole blood at the end of storage were (0.038±0.023 8) in 2019, (0.049±0.039 5) in 2020, (0.043±0.040 7) in 2021, (0.049±0.030 7) in 2022, and (0.058±0.054 8) in 2023, respectively; The hemolysis rates (x-+s" />,%) of leukocyte-depleted suspended red blood cells at the end of storage were (0.093±0.050 2) in 2019, (0.086±0.049 5) in 2020, (0.123±0.072 3) in 2021, (0.122±0.052 1) in 2022, and (0.106±0.058 6) in 2023, respectively; The hemolysis rates (x-+s,%) of washed red blood cells at the end of storage were (0.127±0.038 2) in 2019, (0.150±0.066 5) in 2020, (0.121±0.052 2) in 2021, (0.124±0.038 9) in 2022, and (0.128±0.044 3) in 2023, respectively. Conclusion: Hemolysis rates at the end of blood storage of three red blood cell components were significantly lower than the limits specified in Quality Requirements for Whole Blood and Components (GB18469-2012), as well as standards from the EU, AABB and the United States. The results demonstrate excellent product quality control. A regional internal control standard of <0.2% is proposed for hemolysis rates at the end of storage.

Objective:To observe the effects of acupuncture and moxibustion on ubiquitin-like containing PHD and RING finger domains 1(UHRF1)and DNA methyltransferase 1(DNMT1)in ectopic endometrium of rats with endometriosis(EMS). Methods:Forty Sprague-Dawley rats were randomly divided into a sham operation group with 10 rats and a model-building group with 30 rats according to body mass.EMS rat models were established in the model-building group and then were divided into a model group,an acupuncture and moxibustion group,and a progesterone group,with 10 rats in each group.All rats were fixed by a fixator.The sham operation group and the model group were given normal saline by gavage.The acupuncture and moxibustion group received acupuncture at Xuehai(SP10)and Sanyinjiao(SP6),moxibustion at Guanyuan(CV4),and gavage of normal saline.The progesterone group was given the mixed liquid made of dydrogesterone and normal saline by gavage.After 28 d of treatments,the three diameters(length,width,and height)of EMS rats'ectopic cysts were measured,the cyst volumes were calculated,the volumes before intervention were subtracted,and the difference values were used to evaluate the growth of ectopic cysts.UHRF1 and DNMT1 mRNA and protein levels in normal endometrium,eutopic endometrium,and ectopic endometrium were detected by real-time polymerase chain reaction and immunohistochemistry. Results:There was no significant difference in the ectopic cyst volume difference between the acupuncture and moxibustion group and the progesterone group(P>0.05),but they were smaller than that of the model group(P<0.05).The levels of UHRF1 and DNMT1 mRNA and protein in the ectopic endometrium of the model group were lower than those in the normal endometrium(P<0.05).The levels of DNMT1 mRNA and UHRF1 protein in the eutopic endometrium of the model group were lower than those in the normal endometrium(P<0.05).The levels of UHRF1 mRNA and protein and the level of DNMT1 protein in the ectopic endometrium of the acupuncture and moxibustion group were higher than those in the model group(P<0.05),and the level of UHRF1 mRNA was higher than that in the progesterone group(P<0.05).The level of DNMT1 mRNA in the eutopic endometrium of the acupuncture and moxibustion group was higher than that in the model group(P<0.05).The levels of UHRF1 and DNMT1 mRNA and protein in the acupuncture and moxibustion group were insignificantly different from those in the normal endometrium(P>0.05). Conclusion:Acupuncture and moxibustion may up-regulate the levels of UHRF1 mRNA and UHRF1 and DNMT1 proteins in the ectopic endometrium to the normal level so as to reduce the volume of ectopic cysts and cure EMS in rats.

Objective:To investigate the central mechanism of moxibustion in treating chronic inflammatory visceral pain(CIVP)and its analgesic effect from the perspective of the p38 mitogen-activated protein kinase(MAPK)/Ets-like transcription factor 1(ELK1)signaling pathway in the spinal cord. Methods:Clean-grade male Sprague-Dawley rats were randomly divided into a normal group,a model group,a herb-partitioned moxibustion(HPM)group,a sham-HPM group,a p38 MAPK inhibitor group,and a dimethyl sulfoxide(DMSO)group.CIVP rat models were prepared using an enema mixture of 2,4,6-trinitrobenzene sulfonic acid solution and 50%ethanol.The HPM group was treated with HPM;the sham-HPM group was treated the same as the HPM group,but the moxa cones were not ignited;rats in the p38 MAPK inhibitor group received L5-L6 intrathecal injection of p38 MAPK inhibitor(SB203580);rats in the DMSO group received L5-L6 intrathecal injection of 2%DMSO.Abdominal withdrawal reflex(AWR),mechanical withdrawal threshold(MWT),and thermal withdrawal latency(TWL)were used to observe pain-related behaviors in each group.Hematoxylin-eosin staining was used to observe the morphological changes in rat colon tissue.Western blotting and real-time quantitative reverse-transcription polymerase chain reaction were used to detect the phosphorylated protein and mRNA expression of apoptosis signal-regulating kinase 1(ASK1),MAPK kinase(MKK)3/6,p38 MAPK,ELK1,and mitogen and stress-activated protein kinase 1(MSK1)in the spinal cord. Results:Compared with the normal group,CIVP rats had severe colonic inflammatory injuries,and the pathological injury scores increased significantly,along with increased AWR scores under different colorectal distension(CRD)stimulation pressures and decreased MWT and TWL;the mRNA and phosphorylated protein expression of p38 MAPK,ELK1,MSK1,ASK1,MKK3,and MKK6 all increased in the spinal cord(P<0.01).After HPM treatment,the colon injuries were repaired,and the pathological injury scores decreased;under different CRD stimulation pressures,the AWR scores decreased,and the MWT and TWL increased;the mRNA and phosphorylated protein expression of p38 MAPK,ELK1,ASK1,and MKK3 in the spinal cord also decreased,with statistically significant differences compared with the model group and the sham-HPM group(P<0.01).There were no significant differences in the above indicators between the HPM group and the p38 MAPK inhibitor group(P>0.05),and the same was true regarding the comparisons between the model group and the DMSO group. Conclusion:HPM exerted analgesic effects via downregulating the mRNA and phosphorylated protein expression of ASK1,MKK3,p38 MAPK,and ELK1 in the spinal cord of CIVP rats.The inhibition of spinal p38 MAPK/ELK1 signaling pathway activation may be one of the mechanisms by which HPM relieves pain in CIVP.

With the change of lifestyle,the obese population is gradually increasing,and the prevalence of type 2 diabetes mellitus(T2DM)is increasing year by year,while the age of onset is declining year by year.Diabetic retinopathy(DR),as one of the common complications of T2DM,has a serious impact on the quality of life of patients.At present,there is no way to predict and completely stop the progression of DR.Studies have shown that vitamin D supplementation can effectively alleviate DR in vitamin D deficiency patients,which is expected to become a new idea and method to predict and treat DR.This article-reviews the role of vitamin D in the occurrence and development of DR,as well as its therapeutic effect and mechanism on DR,in order to provide a basis for the application of vitamin D supplementation in the prevention and treatment of DR.

Objective To investigate the real-world factors influencing the clinical outcome of Febrile neu-tropenia(FN)in oncology patients.Methods We conducted a retrospective analysis of clinical data from 130 FN patients admitted to our hospital between January 2020 and December 2022.The patients were categorized into three groups based on their clinical efficacy:cured group,effective group,and ineffective group.A comparison was made among the three groups regarding general data and laboratory examination results.Univariate and ordered multicategorical logistic regression analyses were performed to identify factors affecting the clinical efficacy of FN.Results The overall effective rate of FN in our hospital was 86.15%.Univariate analysis revealed statistically significant differences among the three patient groups regarding the duration of granulomatous defects,Physical Status Score(PS Score),procalcitonin(PCT)levels,and timing of administration(P＜0.05).Ordinal multicat-egorical logistic regression analysis demonstrated that patients with PS scores＜2,granulomatous defects lasting less than 7 days,and PCT levels below 0.5 ng/mL exhibited better clinical treatment outcomes.Conclusion In the management of FN,it is crucial to prioritize patients with high PS scores and elevated PCT levels while optimizing drug utilization to enhance clinical efficacy.Timely intervention should be implemented to address granulopathy and improve overall clinical outcomes.

Objective:To evaluate the clinical efficacy, tolerability and safety of adjunctive perampanel in focal epilepsy patients≥12 years old.Methods:One hundred and nineteen focal epilepsy patients≥12 years old accepted adjunctive perampanel in Department of Neurology, First Affiliated Hospital of Guangxi Medical University from July 2020 to December 2022 were chosen. At 1-3 months, 4-6 months, 7-9 months and 10-12 months after adjunctive perampanel, seizure frequency changes every 28 d, medication retention rate and adverse reactions were recorded to evaluate the clinical efficacy (a reduction in seizure frequency≥50% from baseline was defined as overall valid treatment), tolerability and safety of adjunctive perampanel. According to efficacy results after adjunctive perampanel of 4-6 months (short-term) and 10-12 months (long-term), these patients were divided into valid group and invalid group; and the influencing factors for short-term and long-term efficacy were analyzed.Results:At 1-3, 4-6, 7-9, 10-12 months after adjunctive perampanel, reduction in seizure frequency every 28 d was 66.7% (24.3%, 97.2%), 77.5% (48.6%, 100%), 94.6% (50%, 100%), 100% (70.9%, 100%), enjoying overall valid rate of 60.2% (59/98), 75.0% (7/76), 78.9% (45/57), 86.5% (32/37). The retention rate at 3, 6, 9 and 12 months after adjunctive perampanel was 85.2% (98/115), 67.9% (76/112), 54.3% (57/105), 41.1% (37/90). Adverse reactions were reported in 33 patents (27.7%), mainly with dizziness and secondly with mental symptoms. After short-term and long-term adjunctive perampanel, no significant difference was noted in gender, initial age of adjunctive perampanel, course of disease, etiology, EEG results, imaging results, number and type of combined anti-seizure drugs, or maximum dose of pirampanel between the valid group and invalid group ( P>0.05). Conclusion:Perampanel has good efficacy, tolerability and safety in adolescents and adults≥12 years old with focal epilepsy; no clear influencing factors for pirampanel valid treatment is found so far.

Fungal keratitis is a serious blinding eye disease. The development of fungal infections depends primarily on the interaction of fungal virulence with host immune defense factors. The cornea is considered an immune-privileged organ, and resident macrophages are the main immune cells that respond to the heterogeneity exhibited by the microenvironment with their polarization. In the early stage of infection, macrophages polarize towards M1, which promotes inflammation and facilitates fungal clearance but produces a cellular storm that exacerbates immune damage; in the late stage of infection, macrophages polarize towards M2, which suppresses the inflammatory response and facilitates tissue repair, but may be immunosuppressed or even immune escape to the detriment of pathogen clearance. The balance between pro-inflammatory and anti-inflammatory responses is key to maintaining the functional integrity of the cornea. Current antifungal drug therapy is limited, so it is particularly important to find a therapeutic target for the inflammatory response triggered by the immune response in addition to antifungal therapy. In this review, the functional and phenotypic characterization of macrophage subsets associated with fungal keratitis was reviewed, more in-depth research is needed to explore the specific mechanisms by which macrophage polarization and their impact on fungal keratitis. Targeted regulation of macrophage differentiation based on their phenotype and function could be an effective approach to treat and manage fungal keratitis in the future.
