OBJECTIVE To investigate the effects and mechanisms of Buyang huanwu decoction （BYHWD） and its active fractions in ameliorating non-alcoholic fatty liver disease. METHODS BYHWD and its effective fractions obtained through ethanol precipitation， as well as 30% ethanol， 50% ethanol， and 75% ethanol fractions （namely， the CC effective fraction， 30YC effective fraction， 50YC effective fraction， and 75YC effective fraction）， were prepared. These preparations were administered to rats via intragastric administration to prepare corresponding drug-containing serum （blank serum and simvastatin-containing serum were prepared using the same protocol）. Human L02 hepatocytes were divided into control group， model group， simvastatin-containing serum group， BYHWD-containing serum group， CC-containing serum group， 30YC-containing serum group， 50YC-containing serum group， and 75YC-containing serum group. Except for the control group， other groups were given 0.2 mol/L oleic acid for 24 h to induce a lipid accumulation model， and then intervened with 20% drug-containing serum/blank serum for 24 h. The lipid deposition in cells was observed， and the proportion of lipid droplet area was calculated； the levels of triglycerides （TG） and indicators of oxidative stress [malondialdehyde （MDA）， superoxide dismutase （SOD）] as well as liver function [alanine amino- transferase （ALT）， aspartate amino-transferase （AST）] in cells were detected； protein and mRNA expressions of AMP-activated protein kinase （AMPK）/sterol regulatory element-binding protein-1 （SREBP-1）/glycerol-3-phosphate acyltransferase （GPAT） signaling pathway were also measured. RESULTS Compared with the control group， cells in the model group exhibited severe cellular steatosis， with a significantly increased proportion of lipid droplet area， as well as the elevated levels of TG， ALT， AST， and MDA in cells， along with significantly up-regulated mRNA and protein expression levels of SREBP-1 and GPAT （P＜0.05）. The level of SOD， mRNA expression of AMPK， as well as the protein phosphorylation level of AMPK were decreased significantly （P＜0.05）. Compared with the model group， cellular steatosis was alleviated in all drug-containing serum groups， and the levels of most of the aforementioned quantitative indicators were significantly reversed （P＜0.05）. CONCLUSIONS BYHWD and its active fractions can exert a therapeutic effect on improving non-alcoholic fatty liver disease by regulating the AMPK/SREBP-1/GPAT signaling pathway， inhibiting oxidative stress responses， and reducing lipid deposition.

AIM: To investigate the distribution characteristics of pathogens in patients with post-traumatic infectious endophthalmitis(PTIE)and their relationship with serum levels of macrophage inflammatory protein 1α(MIP-1α), heat shock protein 70(HSP70), and soluble triggering receptor expressed on myeloid cells 1(sTREM-1).METHODS:A total of 157 patients with PTIE from the Handan City Eye Hospital(The Third Hospital of Handan)from May 2023 to May 2025 were selected as the study group. They were divided into a good prognosis group and a poor prognosis group based on their uncorrected visual acuity at discharge. Meanwhile, 157 patients with ocular trauma but without endophthalmitis during the same period were selected as control group 1, and 157 healthy volunteers who underwent physical examinations during the same period were selected as control group 2. Aqueous humor and vitreous fluid samples were collected from the study group to detect the distribution of pathogens. The levels of serum MIP-1α, HSP70, and sTREM-1 were measured using the enzyme-linked immunosorbent assay. Multivariate Logistic regression analysis was performed to identify risk factors for poor prognosis. The predictive value of serum MIP-1α, HSP70, and sTREM-1 levels for poor prognosis was evaluated using receiver operating characteristic(ROC)and decision curve analysis(DCA).RESULTS: The general data of the participants in the three groups was comparable. A total of 173 pathogens were detected in the 157 patients with PTIE, with Gram-positive bacteria being the predominant type. The levels of serum MIP-1α and sTREM-1 in the study group were higher than those in control groups 1 and 2, while the level of HSP70 was lower than those in control groups 1 and 2(all P<0.05). There were no significant differences in the levels of serum MIP-1α, HSP70, and sTREM-1 between control groups 1 and 2(all P>0.05). In the poor prognosis group, the time of wound suture was ≥24 h, the wound location was in zones II/III, the type of trauma was rupture, the proportion of rupture injuries, and the levels of serum C-reactive protein, MIP-1α, and sTREM-1 were higher than those in the good prognosis group, while the level of HSP70 was decreased(all P<0.001). Multivariate Logistic regression analysis showed that the time of wound suture, wound location, type of trauma, C-reactive protein, MIP-1α, HSP70, and sTREM-1 were risk factors for poor visual prognosis in patients with PTIE(all P<0.05). The ROC curve results showed that the combined prediction of serum MIP-1α, HSP70, and sTREM-1 for poor visual prognosis in PTIE patients had an AUC value of 0.965, which was significantly higher than that of individual predictions(ZMIP-1α, ZHSP70, ZsTREM-1=3.628, 4.705, 3.930, all P<0.05). Additionally, the DCA curve showed that the combined prediction had a higher net benefit rate than individual predictions in the high-risk threshold range of 0.03-0.97.CONCLUSION:Gram-positive bacteria are the predominant type of pathogenic bacteria in patients with PTIE, with elevated levels of serum MIP-1α and sTREM-1 and decreased levels of HSP70. The combined detection of these three factors has a high predictive efficacy for visual prognosis in patients.

AIM: To compare the efficacy of highly aspherical lenslets(HAL), defocus incorporated multiple segments(DIMS), and single-vision spectacle lenses(SVL)in slowing myopia progression in children and adolescents.

METHODS: In this retrospective cohort study, myopic children and adolescents aged 6-16 y who were prescribed spectacle lenses at the hospital between January 2023 and June 2023 were included. Participants were divided into the HAL, DIMS, and SVL groups according to the correction modality voluntarily selected by participants and their guardians. The follow-up duration was 12 mo. After 12 mo of wear, changes from baseline in sphere, cylinder, spherical equivalent(SE), axial length(AL), flat corneal curvature(K1), steep corneal curvature(K2), mean corneal curvature, and binocular visual function \〖binocular cross-cylinder(BCC), negative/positive relative accommodation(NRA/PRA)\〗 were compared among the three groups after 12-month spectacle wear. Three groups were further stratified by age into age≤10 y and age>10 y subgroups to explore the effect of age on myopia control efficacy of defocus lenses.

RESULTS: A total of 159 myopic participants(159 eyes; only the right eye was included for each subject)were enrolled. In the HAL group(55 participants), there were 24 males and 31 females, with a mean age of 10.07±2.14 y. The DIMS group consisted of 60 participants(33 males, 27 females), with a mean age of 10.02±1.88 y. The SVL group included 44 participants(21 males, 23 females), with a mean age of 10.59±1.93 y. There were no significant differences in K1, K2, mean corneal curvature, NRA, BCC, and PRA among the three groups after 12-month spectacle wear(all P>0.05). There were statistically significant differences in the changes in sphere, SE, and AL(all P<0.05). The changes in sphere, cylinder, SE, and AL in the HAL and DIMS groups were significantly lower than those in the SVL group(all P<0.0167). The DIMS group showed a significantly smaller cylinder progression than the SVL group(P<0.0167). In participants aged≤10 y, the change in spherical power in the HAL group was significantly smaller than those in the DIMS group and SVL group after 12-month spectacle wear(all P<0.0167). The change in cylindrical power in the DIMS group was smaller than that in the SVL group(all P<0.0167). Among participants aged>10 y, the changes in spherical power, SE, and AL in both the HAL group and DIMS group were significantly smaller than those in the SVL group after 12-month spectacle wear(all P<0.0167).

CONCLUSION: Both HAL and DIMS lenses can effectively slow the progression of refractive error and AL elongation in children and adolescents, without significant adverse effects on binocular visual function. Among children≤10 y, HAL lenses yield superior spherical power control, whereas DIMS lenses provide better astigmatism control than SVL.

Retinal vein occlusion (RVO) is a common retinal vascular disease, and macular edema (ME) is the most common cause of visual impairment in eyes with RVO.Intravitreal injection of anti-vascular endothelial growth factor (VEGF) has been advocated as a first-line therapy for ME secondary to RVO.After anti-VEGF treatment, the patient's visual function recovers well in the short term, but the long-term efficacy is unstable and the recurrence rate of ME is high.Therefore, it is of great clinical value to predict the factors influencing the recurrence of ME, which would help determine which patients should receive frequent follow-up and more aggressive treatment to achieve better clinical outcomes.In this paper, the influencing factors of recurrence of ME secondary to RVO are summarized, including disorganization of retinal inner layer, change in the macular microvascular structure, change in choroid thickness, the non-perfusion area between different areas of the retina, inflammatory cytokines, retinal blood flow and blood flow velocity, etc., which can provide an important basis for patient counseling, clinical diagnosis and treatment and prognostic follow-up.

Objective:To explore the surgical efficacy of cervical cerclage with cervical length (CL) <10 mm and emergency cerclage.Methods:From January 2013 to June 2022, a total of 98 singleton pregnant women who underwent ultrasound-indicated cervical cerclage because of CL<10 mm in the second trimester and underwent emergency cervical cerclage because of cervical dilation found by physical examination in Peking University First Hospital were enrolled. The differences in clinical data between the <34 weeks delivery group (25 cases) and the ≥34 weeks delivery group (73 cases) were compared. Meanwhile, according to different cervical status, they were divided into CL<10 mm group (43 cases) and cervical dilatation group (55 cases), and the cervical dilatation group was further divided into cervical dilatation <4 cm group and cervical dilatation ≥4 cm group. The clinical data and pregnancy outcomes of pregnant women with different cervical status were compared.Results:(1) There were significant differences in the proportion of preoperative CL<10 mm and the degree of preoperative cervical dilation between the <34 weeks delivery group and the ≥34 weeks delivery group (all P<0.05). (2) After cervical cerclage, compared with women in the cervical dilatation group, the prolonged gestational age in the CL<10 mm group was longer [(10.5±4.6) vs (14.3±3.4) weeks], the gestational age at delivery was later (median: 35.7 vs 38.0 weeks), the preterm birth rates before 37 and 34 weeks were lower, the late abortion rate was lower [9% (5/55) vs 0 (0/43)], and the newborn birth weight was higher, the differences were statistically significant (all P<0.05). (3) Compared with the cervical dilation ≥4 cm group, the prolonged gestational age of the cervical dilatation <4 cm group was longer [(7.5±5.3) vs (11.1±4.2) weeks], the gestational age at delivery was later (median: 29.2 vs 36.0 weeks), and the birth weight of the newborn was higher (all P<0.05). The late abortion rate of cervical dilatation <4 cm group was lower than that of cervical dilatation ≥4 cm group [7% (3/45) vs 2/10; P=0.220]. Conclusions:Timely cervical cerclage in individuals with CL<10 mm could reduce preterm birth rate before 34 weeks gestation, and the pregnancy outcome is better than that of individuals with cervical dilation. Moreover, the pregnancy outcome of cervical cerclage in women with cervical dilation <4 cm is significantly better than that in women with cervical dilatation ≥4 cm.

Objective:To analyze and compare the reporting data of adverse events following immunization (AEFI) of influenza vaccines in Fujian Province from 2019 to 2023.Methods:Using the National Immunization Program Information Management System, the AEFI reports and vaccination data of influenza vaccines in Fujian Province from 2019 to 2023 were collected, and the reporting rates and clinical characteristics of AEFI of 6 types of influenza vaccines were compared. The 6 types of vaccines in the analysis were as follows: trivalent inactivated influenza vaccines (IIV3) for 6-35 months old people, IIV3 for ≥3 years old people, trivalent live attenuated nasal spray vaccine (LAIV3) for 3-17 years old people, quadrivalent inactivated influenza vaccines (IIV4) for 6-35 months old people, IIV4 for ≥6 months old people, and IIV4 for ≥3 years old people.Results:From 2019 to 2023, a total of 87 687.21 million doses of influenza vaccine were vaccinated in Fujian Province, and 510 cases of AEFI were reported, with a reporting rates of 5.82 per 100 000 doses. Among the 510 cases, 443 (86.86%) were general reactions, 56 (10.98%) were abnormal reactions, 1 (0.20%) was psychogenic reactions, and 10 (1.96%) were coincidence. There were no reports of vaccination accidents and vaccine quality accidents. The reporting rates of AEFI were relatively higher in 2019 and 2020 (18.38 and 18.00 per 100 000 doses, respectively), and lower in 2021, 2022 and 2023 (8.91, 10.68 and 2.30 per 100 000 doses, respectively); the differences were statistically significant (all P<0.05). The differences of reporting rates of AEFI between IIV3 for 6-35 months old people and IIV4 for 6-35 months old people, the injectable vaccines and nasal spray vaccines were not statistically significant. However, the reporting rates of overall AEFI, general reactions and abnormal reactions of IIV3 for ≥3 years old people were all higher than those of IIV4 for ≥3 years old people (7.77 per 100 000 doses vs. 3.88 per 100 000 doses, 6.18 per 100 000 doses vs. 3.59 per 100 000 doses, 1.41 per 100 000 doses vs. 0.19 per 100 000 doses). The reporting rates of overall AEFI and general reaction of IIV3 for 6-35 months old people were both higher than those of IIV3 for ≥3 years old (16.47 per 100 000 doses vs. 7.77 per 100 000 doses, 13.05 per 100 000 doses vs. 6.18 per 100 000 doses), and the differences were statistially significant (all P<0.05). The reporting rates of general abnormal reactions of IIV4 for 6-35 months old and ≥ 6 months old people were both higher than those of IIV4 for ≥3 years old people (14.73 per 100 000 doses and 9.52 per 100 000 doses vs. 3.88 per 100 000 doses); the reporting rates of general reactions and abnormal reactions of IIV4 for ≥6 months old people were both higher than those of IIV4 for ≥3 years old people (12.94 per 100 000 doses vs. 3.59 per 100 000 doses, 1.34 per 100 000 doses vs. 0.19 per 100 000 doses), the differences were statistcially significant (all P<0.05). In terms of clinical features, the reporting rates of fever (37.6-38.5 ℃ and ≥ 38.5 ℃), local redness and swelling (diameter 2.6-5.0 cm), and local induration (diameter ≤2.5 cm and 2.6-5.0 cm) after vaccination of IIV3 for ≥3 years old people were higher than those of IIV4 for ≥ 3 years old people (1.41 per 100 000 doses vs. 0.64 per 100 000 doses, 3.00 per 100 000 doses vs. 1.16 per 100 000 doses); the reporting rates of allergic rash and angioedema of IIV3 for ≥ 3 years old people were higher than those of IIV4 for ≥3 years old people (0.53 per 100 000 doses vs. 0.12 per 100 000 doses, 0.35 per 100 000 doses vs. 0); the differences were statistically significant (all P<0.016 7). Conclusions:The reporting rates of AEFI for influenza vaccines in Fujian Province from 2019 to 2023 was showing a downward trend. The AEFI was mainly general reactions. The reporting rates of AEFI were different among different influenza vaccines, but the overall safety was good.

Objective:To analyze the effect of joint management of type 2 diabetes mellitus (T2DM) between specialty and community under the model of National Diabetes Prevention and Control Center (DPCC).Methods:A total of 2 527 T2DM patients managed by DPCC Pingshan Center of Shenzhen from January 1, 2022 to December 31, 2024 were retrospectively included. After management, the rate of downturn, reexamination rate, blood pressure compliance rate, metabolic indicators (waist circumference, body mass index, fasting blood glucose, glycosylated hemoglobin, blood lipids) and screening rate of chronic complications of diabetes (atherosclerotic cardiovascular disease, microvascular disease, diabetic peripheral neuropathy) were analyzed. Those included 2022 ( n=564), 2023 ( n=1 477), and 2024 ( n=2 527). Results:The downturn rate in 2022, 2023 and 2024 increased year by year (22.8% vs 67.2% vs 89.9%, P<0.01), and the review rate (41.1% vs 62.2% vs 52.7%, P<0.01), complication screening rate (51.6% vs 85.3% vs 62.2%, P<0.01), blood pressure compliance rate (53.1% vs 78.0% vs 67.2%, P<0.01), body mass index compliance rate (13.2% vs 17.3% vs 28.6%, P<0.01), fasting blood glucose meeting rate (46.4% vs 60.2% vs 68.5%, P<0.01), glycated hemoglobin meeting rate (58.4% vs 63.2% vs 45.6%, P<0.01) were relatively improved. Waist circumference compliance rate (30.6% vs 27.7% vs 21.6%) and blood lipid compliance rate (33.6% vs 35.5% vs 31.9%) were not significantly improved, and the review rate, blood pressure compliance rate and complication screening rate in 2024 were lower than those in 2023 and higher than those in 2022. Conclusions:The combined management of type 2 diabetes under the DPCC model has significant effects on improving the down-conversion rate, rediagnosis rate, blood pressure compliance rate, metabolic index compliance rate and the screening rate of diabetes-related chronic complications in patients with diabetes. At the same time, it was also found that with the progress of hierarchical diagnosis and treatment, the review rate, complication screening rate, blood pressure, waist circumference, blood lipid and glycosylated hemoglobin reached the standard of patients decreased compared with the previous situation, which needs to be further analyzed and improved.

Objective:To construct and validate a risk prediction model for early miscarriage during subsequent pregnancy in patients with recurrent spontaneous abortion (RSA) based on autoantibodies and ultrasound endometrial receptivity parameters.Methods:A retrospective analysis was performed on the clinical data of 124 RSA patients who became pregnant again and were admitted to the Xi ′an Daxing Hospital from July 2018 to July 2023. According to the occurrence of early miscarriage, the patients were divided into the early miscarriage group (46 cases) and the non-early miscarriage group (78 cases). The influencing factors for the occurrence of early miscarriage in RSA patients were analyzed, and a Nomogram model was constructed to predict the risk of early miscarriage. The area under the receiver operating characteristic (ROC) curve (AUC) was used to analyze the predictive efficacy of the prediction model for early miscarriage in RSA patients during subsequent pregnancy.Results:Univariate analysis showed that the positive rates of anti-β2-glycoprotein 1 antibody (aβ2-GP1), thyroglobulin antibody (TGAb), antisperm antibodies (AsAb), anticardiolipin antibodies (ACA), and the resistance index (RI) in the early miscarriage group were greater than those in the non-early miscarriage group, while the endometrial thickness, endometrial volume, vascularization index (VI), and vascularization flow index (VFI) were less than those in the non-early miscarriage group (all P<0.05). Binary logistic regression analysis showed that positive aβ2-GP1 and positive TGAb were independent risk factors for early miscarriage in RSA patients during subsequent pregnancy, while endometrial thickness, endometrial volume, and VFI were independent protective factors (all P<0.05). The Nomogram prediction model constructed based on the above-mentioned influencing factors was internally validated by the Bootstrap method, showing a C-index of 0.847 (95% CI: 0.765-0.958), and the calibration curve for predicting early miscarriage in RSA patients during subsequent pregnancy was close to the ideal curve ( P>0.05). The results of the ROC curve showed that the sensitivity, specificity, and AUC of the Nomogram model for predicting early miscarriage in RSA patients during subsequent pregnancy were 89.10%, 85.90%, and 0.889 (95% CI: 0.815-0.963), respectively ( P<0.05). Conclusions:The Nomogram prediction model established based on positive aβ2-GP1, positive TGAb, endometrial thickness, endometrial volume, and VFI can effectively evaluate the risk of early miscarriage in RSA patients during subsequent pregnancy.
