Objective:To investigate and evaluate the clinical efficacy and safety of a modified anterior approach for transpupillary silicone oil removal combined with phacoemulsification and intraocular lens (IOL) implantation.Methods:A retrospective case-control study. A total of 148 patients (148 eyes) who underwent silicone oil removal combined with cataract surgery at the Department of Ophthalmology, Guangdong Provincial People's Hospital between January 2020 and November 2024 were included in the study. All affected eyes underwent preoperative examinations including best-corrected visual acuity (BCVA), intraocular pressure, corneal topography, and optical coherence tomography (OCT). Based on the method of silicone oil removal, the eyes were divided into two groups: group A (modified anterior approach transpupillary silicone oil removal combined with phacoemulsification and IOL implantation, 99 eyes) and group B (standard pars plana vitrectomy for silicone oil removal combined with phacoemulsification and IOL implantation, 49 eyes). The surgical duration, changes in BCVA and intraocular pressure at 1 day, 7 days, and 1 month postoperatively, as well as the incidence of complications such as corneal edema and its resolution, conjunctival congestion, iris prolapse, posterior capsule rupture, nucleus drop, IOL position, residual silicone oil in the vitreous cavity or anterior chamber, vitreous hemorrhage, recurrent retinal detachment (RD), and choroidal detachment or hemorrhage, were compared between the two groups. The independent sample t-test was used for the comparison of measurement data between the two groups, and the χ2 test was used for the comparison of count data. Results:The operation time of group A and group B was (17.01±1.28) min and (31.62±2.32) min, respectively. The operation time of group A was significantly shorter than that of group B, and the difference was statistically significant ( t=?41.002, P<0.001). The comparison of BCVA ( t =?0.561, ?0.833, ?1.386) and IOP ( t=?0.055, 1.375, ?0.507) between the two groups of affected eyes before surgery and at 1 day and 7 days after surgery showed no statistically significant differences ( P>0.05). There was no silicone oil residual in group A, while 3 eyes in group B were observed with silicone oil residual (6.1%, 3/49). Neovascular glaucoma was observed in one eye. Compared to group A, group B exhibited a statistically significant increase in the incidence of postoperative conjunctival congestion, silicone oil retention, and posterior capsular opacification ( χ2=10.600, 6.187, 92.617; P<0.05). In contrast, no statistically significant differences were observed between the groups in the incidence of corneal edema or recurrent retinal detachment (RD) ( χ2=0.272, 1.557; P>0.05). No intraoperative complications, such as iris prolapse, posterior capsular rupture, nucleus drop, zonular dehiscence, choroidal detachment, or hemorrhage, occurred in any of the operated eyes. Furthermore, no postoperative complications, including corneal endothelial decompensation, IOL displacement, or endophthalmitis, were observed during the follow-up period. Conclusion:Compared to the conventional pars plana approach for silicone oil removal combined with cataract surgery, the modified anterior perfusion transpupillary approach demonstrated significantly shorter surgical duration and a reduced incidence of postoperative complications.

Objective To investigate the expression of forkhead box P3(Foxp3)in peripheral blood of children with bronchial asthma and its relationship with airway hyper-responsiveness and body allergy.Methods A total of 80 children with bronchial asthma treated in the Affiliated Hospital of Yangzhou University from July 2024 to June 2025 were selected as experimental group,and 47 health-y children with physical examinations in the same period were selected as control group.Airway hy-per-responsiveness indicators(respiratory resistance,bronchial stimulant reaction threshold,and re-sistance increase slope),body allergy indicators[serum immunoglobulin E(IgE),eosinophil cationic protein(ECP),and eosinophil count(EOS)],pulmonary function indicators[peak expiratory flow(PEF),forced expiratory volume in the first second(FEV,),forced vital capacity(FVC),and the ratio of forced expiratory volume in the first second to forced vital capacity(FEV1/FVC)],and the expression level of Foxp3 in peripheral blood were compared between the two groups.Pearson corre-lation analysis was used to explore the correlations of Foxp3 with airway hyper-responsiveness and body allergy.Results The respiratory resistance and resistance increase slope in the control group were significantly lower than those in the experimental group,while the reaction threshold was signif-icantly higher than that in the experimental group(P＜0.05).The levels of IgE,ECP and EOS in the experimental group were significantly higher than those in the control group(P＜0.05).The FEV1,FVC,PEF,and FEV1/FVC in the experimental group were significantly lower than those in the control group(P＜0.05).The expression level of Foxp3 in the experimental group was(3.04±0.22),which was significantly lower than(4.22±0.41)in the control group(P＜0.05).Foxp3 was significantly correlated with respiratory resistance(r=-0.700,P＜0.001),reaction thresh-old(r=0.704,P＜0.001),resistance increase slope(r=-0.842,P＜0.001),IgE(r=0.864,P＜0.001),ECP(r=-0.684,P＜0.001),and EOS(r=-0.854,P＜0.001).Con-clusion The decreased Foxp3 in peripheral blood in children with bronchial asthma is associated with aggravated airway hyper-responsiveness and body allergy,suggesting that Foxp3 may be in-volved in the pathogenesis of bronchial asthma.

Tumor microenvironment(TME)is a complex cellular environment where tumor cells reside,along with various types of cells and extracellular components surrounding the tumor cells.Immune cells are key components of TME,including tumor-associated macrophages(TAMs),myeloid-derived suppressor cells(MDSCs),lymphocytes,regulatory T cells(Tregs),natural killer cells(NK cells),dendritic cells(DCs),and many others.It is worth noting that drug resistance is currently a major factor limiting the efficacy of cancer treatment methods such as chemotherapy,radiotherapy,targeted therapy,and immunotherapy,and a leading cause of treatment failure.Research has found that the development of drug resistance in tumor cells is the result of interactions between tumor cells and TME.Consequently,overcoming drug resistance in tumors caused by TME is considered a significant challenge in cancer treatment.In recent years,with in-depth research into immune cells within TME,significant progress has been made in understanding the specific mechanisms by which immune cells regulate drug resistance in tumor cells.Furthermore,therapeutic strategies that target these immune cells,signaling pathways,or cytokines have been shown to effectively combat tumor drug resistance and enhance the therapeutic outcomes of cancer treatment.This article reviews the research advancements regarding the roles of TAMs,MDSCs,Tregs,and NK cells in tumor drug resistance within TME and discusses the development of targeting strategies to overcome this resistance.Additionally,we explore the relationship of tumor-associated neutrophils(TANs)and B regulatory cells(Bregs)with tumor drug resistance.It is hoped that this review will offer insights and serve as reference for reducing tumor drug resistance and improving the efficacy of anti-tumor therapies.

Objective To investigate the predictive value of serum lipoprotein-associated phospho-lipase A2(Lp-PLA2)for long-term prognosis of elderly patients with stable coronary heart dis-ease(CHD).Methods A retrospective trial was conducted on 198 patients with stable CHD ad-mitted to our hospital from January 2016 to December 2018.All of them were followed up for 5 years,and divided into adverse cardiovascular event group(n=42)and control group(n=156)according to whether adverse cardiovascular events occurred during follow-up.Clinical features and Lp-PLA2 level were compared between the two groups.The predictive value of Lp-PLA2 for adverse cardiovascular events was analyzed in elderly patients with stable CHD within 5 years.Re-sults The adverse cardiovascular event group had significantly older age(74.95±7.02 vs 70.17±6.30 years,P=0.000),larger proportions of diabetes(54.76％vs 27.56％,P=0.001),of coronary artery stenosis ≥75％(69.05％vs 47.44％,P=0.013)and of left ventricular ejection fraction(LVEF)＜50％(50.00％vs 28.21％,P=0.008),and higher Lp-PLA2 level(478.38±187.54 U/L vs 308.17±126.73 U/L,P=0.000)when compared with the control group.The AUC value of age and Lp-PLA2 was 0.683(95％CI:0.590--0.776,P＜0.001)and 0.763(95％CI:0.677--0.848,P=0.763),respectively,in predicting the long-term prognosis in elderly patients with stable CHD.Multivariate logistic regression analysis showed that age,diabetes,coronary artery stenosis ≥75％,LVEF＜50％and Lp-PLA2 were independent influencing factors for adverse cardiovascular events within 5 years in elderly patients with stable CHD(P＜0.05,P＜0.01).Con-clusion Increased Lp-PLA2 level is associated with adverse cardiovascular events within 5 years in patients with stable CHD.

【Objective】 To explore the distribution of polymorphisms of miR-208 genes rs8022522 and rs12894524 locus in Guangxi healthy population and compare the differences in the polymorphism distribution in different population. 【Methods】 SNPscan technology was used to detect genotypes of rs8022522 and rs12894524 from 297 healthy people in Guangxi, and the results were compared with other populations from Human genome Haplotype Map(HapMap) data. 【Results】 Three genotypes, namely, AA (2.7%), AG (24.2%) and GG (73.1%), in rs8022522 were found, with the allele frequencies of A and G being 14.8% and 85.2%. The genotypes of rs12894524 locus were TT (1.3%), TG (13.5%) and GG (85.2%), and the frequency of T and G allele was 8.1% and 91.9%, respectively. rs8022522 and rs12894524 locus genotypes and allele frequencies were significantly different from HapMap-CEU, HapMap- YRI and HapMap-TSI (P<0.05). Compared with HapMap-JPT and HapMap-CHB, there was no significant difference in genotype or allele frequency between the two sites (P>0.05). As for the blood lipid level among the three genotypes in rs8022522, the level of high density lipoprotein cholesterol (HDL-C) with GG genotype was significantly different from that in AG group (P<0.05). 【Conclusion】 The polymorphisms of rs8022522 and rs12894524 of miR-208 gene in Guangxi population are different from those in other regions to varying degrees. The polymorphism of rs8022522 locus is related to the level of HDL-C.

Laparoscopic hepatectomy has been routinely used in all tumor types of the liver, but for tumors in the Ⅵ, Ⅶ and Ⅷ segments of the liver (referred to as tumors in a special position of the liver in this paper), laparoscopic hepatectomy has some difficulties in aspect of vision and operation due to the deep anatomical position. In the process of continuous experience accumulation, hepatobiliary surgeons have explored different surgical positions, surgical methods and surgical paths to solve the encountered difficulties. For tumors located in a special position of the liver, conventional laparoscopy, change of surgical posture, thoracoscopic or combined laparoscopy and retroperitoneal laparoscopy are effective and feasible. All of them have their own advantages.

Objective:To analyze the distribution characteristics of peripheral retinopathy in Chinese patients with diabetic retinopathy (DR).Methods:A cross-sectional study. From January to December 2019, 265 cases of 388 eyes of DR patients diagnosed in the eye examination of Guangdong Provincial People's Hospital were included in the study. Among them, there were 211 eyes in 148 males and 177 eyes in 117 females; the average age was 58.4±12.3 years. Ultra-wide-angle fundus imaging (UWF) examination was performed by Daytona in Aalborg, UK. Use Photoshop to simulate the standard 7-azimuth (S7F) area, which was used as the central retinal area 1-7. The peripheral retinal areas 3-7 (P3-P7) were the adjacent peripheral retinal areas of the central retinal area 3-7, respectively. Divided DR into peripheral lesion predominant type (PPL) and central lesion predominant type (PCL). PPL was defined as at least one peripheral retinal area with more severe disease than its adjacent central area. χ 2 test was performed on the difference of PPL composition ratio in each retinal area of eyes with different DR stages. Results:Among 388 eyes, 200 eyes were PPL (51.5%, 200/388). Compared of PPL composition ratios of eyes with different stages of DR, mild non-proliferative DR (NPDR), moderate NPDR, severe NPDR and proliferative DR were 32 (36.8%, 32/87), 89 (55.3%, 89/161)), 42 (51.9%, 42/81), 37 (62.6%, 37/59), the difference was statistically significant ( χ2=11.440, P=0.010). Comparison of the distribution of PPL in each retinal area in DR eyes: in 200 PPL eyes, areas 3, 4, 5, 6, and 7 have 87, 101, 78, 67, and 38 eyes, respectively. The distribution of PPL in each retinal area in DR eyes was compared, and the difference was statistically significant ( χ2=37.640, P<0.001). Conclusions:PPL accounts for 51.5% of the eyes with DR. The DR stage are more severe, the proportion of PPL is higher. The temporal retinal peripheral lesions are the most common.

Objective:Under different diagnostic scenarios, we tried to establish a tuberculosis dynamic model, to predict the incidence burden and to provide evidence for developing the prevention and control programs of tuberculosis.Methods:A systematic dynamic model was established to fit the annual incidence rates of tuberculosis data from the China CDC, between 2005 and 2018. Basic reproductive number ( R0) was calculated. Impact of different diagnostic scenarios on tuberculosis burden was explored by numerical changes in diagnosis-related parameters. Results:Results from the Chi-square test indicated that the model accuracy appeared as: χ2=1.102 ( P=1.000). Also, the computed result showed that R0=0.063<1, indicating that tuberculosis would gradually be disappearing in China. Approaches that including 'reducing the delayed diagnosis time’or 'improving the timely medical treatment’would end the fluctuations of the number of infectious and hospitalized patients and thus leading to continuous reduction in the number of these patients, in a long run. Conclusions:This model fitted well for the trend of tuberculosis incidence rates between 2005 and 2018. Reducing the delay time in diagnosis and improving the rate of timely medical treatment could effectively reduce the long-term burden of tuberculosis. Improvement of this model would be further explored.

Significantly increasing crop yield is a major and worldwide challenge for food supply and security. It is well-known that rice cultivated at Taoyuan in Yunnan of China can produce the highest yield worldwide. Yet, the gene regulatory mechanism underpinning this ultrahigh yield has been a mystery. Here, we systematically collected the transcriptome data for seven key tissues at different developmental stages using rice cultivated both at Taoyuan as the case group and at another regular rice planting place Jinghong as the control group. We identified the top 24 candi-date high-yield genes with their network modules from these well-designed datasets by developing a novel computational systems biology method, i.e., dynamic cross-tissue (DCT) network analysis. We used one of the candidate genes, OsSPL4, whose function was previously unknown, for gene editing experimental validation of the high yield, and confirmed that OsSPL4 significantly affects panicle branching and increases the rice yield. This study, which included extensive field phenotyping, cross-tissue systems biology analyses, and functional validation, uncovered the key genes and gene regulatory networks underpinning the ultrahigh yield of rice. The DCT method could be applied to other plant or animal systems if different phenotypes under various environments with the common genome sequences of the examined sample.
