AIM: To compare the effects of different nucleus chopping methods on the central corneal thickness, corneal endothelial cell(CEC)count and tear inflammatory indicators in patients with hard nucleus cataract.METHODS: Retrospective study. Totally 89 patients(89 eyes)with hard nucleus cataract who treated in our hospital were included from January 2020 to December 2022. According to different intraoperative nucleus chopping methods, the patients were divided into reverse prechop group(46 eyes)and phaco-chop group(43 eyes). The total effective rate of surgery and visual acuity recovery were compared between the two groups. Corneal related indicators(central corneal thickness, CEC count, CEC area), tear inflammatory indicators and tear film function [tear film break-up time(BUT), Chinese Dry Eye Questionnaire(CDEQ), Schirmer Ⅰ test(SⅠt)] were observed before and after surgery in both groups, and the degree of corneal edema was evaluated.RESULTS: The effective phaco time, phaco energy and cumulative complex energy parameters in the phaco-chop group were longer or higher than those in the reverse prechop group(P<0.05). The macular retinal thickness in the reverse prechop group at 7 d and 1 mo after surgery was thinner than that in the phaco-chop group, the central corneal thickness at 3 and 7 d after surgery was also thinner than that in the phaco-chop group, the CEC count at 3 mo after surgery was more than that in the phaco-chop group, the CEC loss rate was lower than that in the phaco-chop group, and the CEC area at 3 mo after surgery was smaller than that in the phaco-chop group(P<0.05). The levels of tear TNF-α and IL-6 at 7 d and 1 mo after surgery in the reverse prechop group were lower than those in the phaco-chop group(P<0.05). The BUT at 1 and 3 mo after surgery was longer in the reverse prechop group than that in the phaco-chop group(P<0.05). The CDEQ score in the reverse prechop group was lower than that in the phaco-chop group at 1 and 3 mo after surgery(P<0.05). The SⅠt at 1 and 3 mo after surgery was higher in the reverse prechop group compared with that in the phaco-chop group(P<0.05). The degree of corneal edema at 1 d after surgery was milder in the reverse prechop group than that in the phaco-chop group(P<0.05). CONCLUSION: Compared with phaco-chop, the application of reverse-chopper prechop combined with phacoemulsification can better reduce the ultrasonic energy in the treatment of hard nuclear cataract, and it is more conducive to reducing the postoperative inflammatory degree, improving the tear film function and relieving the corneal edema degree.

Objective:To investigate the mechanisms of baicalin in treating septic acute liver injury through a combination of network pharmacology and animal experiments.Methods:Thirty male C57BL/6 mice (6 weeks old) were divided into five groups ( n=6): control group (normal saline), model group [lipopolysaccharide (LPS) 10 mg/kg, intraperitoneal injection], low-dose baicalin group (10 mg/kg), high-dose baicalin group (20 mg/kg), and baicalin-only group (20 mg/kg, without LPS). Baicalin was administered orally for 14 consecutive days prior to modeling. Mice were sacrificed 24 h after LPS injection. Alanine transaminase, aspartate transaminase liver tissue histopathology were measured; neutrophil infiltration was visualized using immunofluorescence; mRNA expression levels of interleukin (IL)-1β, IL-17, IL-6, and tumor necrosis factor (TNF)-α were detected by RT-qPCR; and the expression of Toll-like receptor 4 (TLR4) and phosphorylated nuclear factor (NF)-κB proteins were analyzed by Western blotting. Results:In the LPS model group, the ALT, AST, and histopathological injury score were (148.60±22.02) U/L, (81.58±11.59) U/L, and 8.50(7.75, 9.25), respectively. These indicators were significantly reduced in the high-dose baicalin group with (77.90±16.79) U/L, (49.92±14.89) U/L, and 1.00(1.00, 2.25) (all P<0.05). Compared with the LPS group, neutrophil infiltration in the liver of high-dose baicalin group was also significantly reduced [1.18%(0.98%, 1.22%) vs. 6.13%(5.41%, 8.69%), P<0.05]. RT-qPCR results showed that the relative mRNA expression levels of inflammatory cytokines IL-1β [(1.03±0.06) vs. (2.60±0.34)], IL-17 [(1.21±0.12) vs. (2.94 ± 0.39)], IL-6 [(1.37±0.26) vs. (2.73±0.18)], and TNF-α [(1.18±0.10) vs. (3.30±0.92)] were significantly decreased in the high-dose baicalin group compared with the LPS group (all P<0.05). Western blot analysis revealed that the relative protein expression levels of TLR4 [(1.25±0.13) vs. (1.73±0.06)] and phosphorylated NF-κB [(1.25±0.25) vs. (1.79±0.12)] were also significantly lower in the high-dose baicalin group (both P<0.05). Conclusion:Baicalin reduces liver injury in septic mice by downregula-ting the expression of pro-inflammatory cytokines IL-1β, IL-6, TNF-α, and IL-17, potentially through the inhibition of the TLR4/NF-κB signaling pathway.

This paper reports a case of red ear syndrome, a rare clinical condition, treated with acupuncture. At the initial consultation, the diagnosis was unclear from a western medical perspective. The advantage of traditional Chinese medicine in "prioritizing symptoms and syndrome differentiation" was fully utilized. Based on the patient's clinical manifestations, disease progression, tongue and pulse conditions, the treatment addressed the branch by targeting meridian qi stagnation based on the hand-taiyang sinew meridian theory, and treated the root by selecting acupoints according to syndrome differentiation for liver and kidney yin deficiency. A combined treatment of tendon needling and acupuncture produced immediate results after the first session. Subsequent sessions were administered every other day for a total of ten treatments. The patient's ear pain and redness symptoms had nearly disappeared, and a two-month follow-up showed good overall condition.

Objective:To investigate the etiology, clinical features and outcome of isolated anterior cerebral artery (ACA) territory infarction.Methods:Patients with isolated ACA territory infarction admitted to the Affiliated Shuyang Hospital of Xuzhou Medical University from April 2019 to December 2023 were retrospectively included. The demographic and clinical data were collected. The etiology subtypes of stroke were divided into large artery atherosclerosis (LAA), cardioembolism (CE), small vessel occlusion (SVO), stroke of other determined etiology (SOE), and stroke of undetermined etiology (SUE). At 90 days after onset, the modified Rankin Scale was used to evaluate the outcome. 0~2 points were defined as good outcome, and >2 points were defined as poor outcome. Multivariate logistic regression analysis was used to identify independent risk factors for poor outcomes. Results:A total of 67 patients with isolated ACA territory infarction were enrolled, including 31 males (46.27%), aged 67.20±12.59 years. There were 26 patients (38.81%) of LAA type, 10 (14.93%) of CE type, 7 (10.45%) of SVO type, 12 (17.91%) of SOE type, and 12 (17.91%) of SUE type. Fifty-two patients (77.61%) had good outcome, while 15 (22.39%) had poor outcome. There were significant differences in gender, diabetes, atrial fibrillation, antithrombin-Ⅲ activity, urinary incontinence, cognitive impairment, and the baseline National Institutes of Health Stroke Scale (NIHSS) score among different etiological subtypes (all P<0.05). Multivariate logistic regression analysis showed that previous stroke history (odds ratio 17.995, 95% confidence interval 1.276-253.852; P=0.032) and high baseline NIHSS score (odds ratio 2.094, 95% confidence interval 1.333-3.292; P=0.001) were the independent risk factors for poor outcome. Conclusions:The most common etiology of isolated ACA territory infarction is LAA, and most patients have good outcome. Previous stroke history and high baseline NIHSS score are the independent risk factors for poor outcome.

Since COVID-19 infection,many infected patients have developed multiple systemic symptoms that persist long after 3 months of infection,which is called Long COVID.Numerous studies have shown that fatigue is the most common symptom among the many symptoms of Long COVID that has severely impacted the quality of their life.Therefore,it is particularly important to understand the mechanisms by which Long COVID causes fatigue symptoms.This article summarizes the possible mechanisms of Long COVID fatigue,including immune response,oxidative stress,and affecting the central nervous system,by combing through the relevant literature,aiming to increase clinical awareness of fatigue induced by Long COVID and to provide certain ideas for its treatment.
