Objective: To investigate the trends in incidence and mortality of lung cancer in Huangpu District, Shanghai Municipality from 2002 to 2019, so as to provide the evidence for formulating lung cancer prevention and control measures. Methods: Data of lung cancer incidence and mortality among residents in Huangpu District from 2002 to 2019 were collected through the Shanghai Cancer Registration and Reporting Management System. The crude incidence and mortality of lung cancer was calculated, and standardized by the data from the Chinese Fifth National Population Census in 2000 (Chinese-standardized rate) and the Segi's world standard population in 1960 (world-standardized rate). The trends in incidence and mortality of lung cancer among residents by age and gender were evaluated using annual percent change (APC). Results: A total of 12 965 cases of lung cancer were reported in Huangpu District from 2002 to 2019, and the crude incidence rate was 80.66/105, the Chinese-standardized incidence rate was 34.54/105, and the world-standardized incidence rate was 31.30/105, all showing upward trends (APC=4.588%, 2.933% and 3.247%, all P<0.05). A total of 10 102 deaths of lung cancer were reported, and the crude mortality rate was 62.30/105, showing an upward trend (APC=0.959%, P<0.05); the Chinese-standardized mortality was 25.93/105, and the world-standardized mortality was 22.05/105, both showing downward trends (APC=-1.282% and -1.263%, both P<0.05). The crude incidence and mortality rates of lung cancer in males were higher than those in females (101.39/105 vs. 60.52/105, 85.45/105 vs. 39.87/105, both P<0.05). The crude incidence and mortality rates of lung cancer showed upward trends with age (both P<0.05), reaching their peaks in the age groups of 80-<85 years (341.37/105) and 85 years or above (355.97/105), respectively. Conclusions The incidence of lung cancer showed an upward trend, while the mortality showed a downward trend in Huangpu District from 2002 to 2019. Elderly men were the high-risk group for lung cancer incidence and mortality.

In 2022， Hainan provincial government launched the project for the prevention and control of viral hepatitis with the goals of a hepatitis B screening rate of 90%， a diagnostic rate of 90%， and a treatment rate of 80% among people aged 18 years and above by the year 2025， and the main intervention measures include population-based prevention， case screening， antiviral therapy， and health management. As of December 31， 2024， a total of 6.875 million individuals in the general population had been screened for hepatitis B， with a screening rate of 95.6%. A total of 184 710 individuals with positive HBsAg were identified， among whom 156 772 were diagnosed through serological reexamination， resulting in a diagnostic rate of 84.9%. A total of 50 742 patients with chronic hepatitis B were identified， among whom 42 921 had hepatitis B-specific health records established for health management， with a file establishment rate of 84.6%. A total of 31 553 individuals received antiviral therapy， with a treatment rate of 62.2%. A total of 2.503 million individuals at a high risk of hepatitis C were screened， among whom 4 870 tested positive for HCV antibody and 3 858 underwent HCV RNA testing， resulting in a diagnostic rate of 79.2%， and 1 824 individuals with positive HCV RNA were identified， among whom 1 194 received antiviral therapy， with a treatment rate of 65.5%. In addition， 159 301 individuals with negative HBsAg and anti-HBs and an age of 20 — 40 years were inoculated with hepatitis B vaccine free of charge. Through the implementation of the project for the prevention and control of viral hepatitis， a large number of hepatitis patients have been identified， treated， and managed in the province within a short period of time， which significantly accelerates the efforts to eliminate the crisis of viral hepatitis.

Objective To explore the effect and mechanism of anti-mesangial cell-proliferation-peptide 2(AMPP2)on mesangial cell proliferation induced by transforming growth factor β1(TGF-β1).Methods Mesangial cells were cultured in vitro and treated with TGF-β1(10 μg/L)and AMPP2(10 ng/L).According to different intervention factors,mesangial cells were divided into four groups:the control group,the AMPP2 group,the TGF-β1 group and the TGF-β1+AMPP2 group.The proliferation activity of mesangial cells was detected by CCK-8.The relative protein expression of cyclin dependent kinase 4(CDK-4),cyclin dependent kinase 6(CDK-6),proliferating cell nuclear antigen(PCNA),α-smooth muscle actin(α-SMA),collagen-Ⅰ(COL-Ⅰ)and fibronectin(FN)were examined by Western blot assay.The relative mRNA expression of α-SMA,COL-Ⅰ and FN were detected by qPCR.Results Compared with the control group,proliferation activity of mesangial cells was significantly increased in the TGF-β1 group(P＜0.05).The proliferation activity of mesangial cells was markedly decreased in the TGF-β1+AMPP2 group compared with that of the TGF-β1 group(P＜0.05).Compared with the control group,protein levels of CDK-4,CDK-6,PCNA,α-SMA,COL-Ⅰand FN in cells were significantly increased in the TGF-β1 group(P＜0.05),as well as the mRNA levels of α-SMA,COL-Ⅰand FN(P＜0.05).In the TGF-β1+AMPP2 group,the protein and mRNA levels of α-SMA,COL-Ⅰand FN and the protein levels of CDK-4,CDK-6 and PCNA were markedly decreased compared with those of the TGF-β1 group(P＜0.05).Compared with the control group,levels of p-SMAD3/SMAD3 was remarkably upregulated in the TGF-β1 group(P＜0.05),while levels of p-SMAD3/SMAD3 was remarkably downregulated in the TGF-β1+AMPP2 group compared with those of the TGF-β1 group(P＜0.05).Conclusion AMPP2 may inhibit mesangial cell proliferation by regulating TGF-β1/SMAD3 pathway.

Objective: To investigate the association of parental knowledge and skills in myopia prevention and control with healthy eye behavior in primary school children, so as to provide a basis for accurate family education. Methods: A total of 4 979 students in grades 1-5 from eight elementary schools in Pudong New Area were sampled between October and December in 2022 by using a stratified cluster sampling method. A self administered questionnaire was used to assess healthy eye behavior in primary school children and parental knowledge and skills in myopia prevention and control. The Chi squared test, independent samples t-test and Logistic regression were used to analyse the association between parental knowledge and skills in myopia prevention and control and healthy eye behaviour in primary school children. Results: Parents of primary school children with a high level of knowledge and skills in myopia prevention and control were 50.97% and 56.36%, respectively. The knowlegde entry scores for parents of lower and middle elementary school students were higher than those of parents of upper primary students with respect to their understanding, on the main causes of myopia in their children, the correct knowledge of myopia prevention and control, the role of family members in helping each other to manage and treat myopia in their children and the parents responsibility to teach their children to use their eyes correctly and scientifically (3.05±1.21, 2.97±1.20; 5.92±0.68, 5.83±0.86; 4.46±0.88, 4.40±0.93; 3.88±1.04, 3.72±1.07); all differences were statistically significant (t=2.04, 3.39, 2.00, 4.87, P<0.05). The differences in the scores of parents of primary school children in different grades for all items were statistically significant (t=2.93-7.31, P<0.05) in the skill entries. Parental knowledge levels were poor for items of full scores that assessed the following: knowing the main causes of their childrens myopia, awareness of the correct knowledge of myopia prevention and control measures, awareness of Comprehensive Prevention and Control Strategy for Children and Adolescents with Myopia, and concerning that their childrens future education and employment will be affected by myopia, understanding the responsibility of parents for guiding children to use their eyes scientifically and correctly, with 12.71%, 22.90%, 19.30%, 21.83% and 22.47% respectively. Parental skills were poor for items of full scores that assessed the following:reminding their children to rest their eyes when doing homework, reading or writing, deliberately avoiding mobile phone use when spending time with their children, the number of times which taking children to the hospital for refractive screening in the past year, and giving their children extra learning tasks, with 33.26%, 15.12%, 9.00% and 5.36% respectively. Compared to parental knowledge in myopia prevention and control, parental skills had a more pronounced effect on the four dimensions of healthy eye behavior (reading and writing, screen time, outdoor activities, and sleep duration) among students in different grades (OR=1.41-3.37, P<0.05). Conclusions Parental knowledge and skills in myopia prevention and control are still insafficient, associated with healthy eye behavior in primary school children. There is a need to strengthen accurate health education for parents on the prevention and control of myopia, to cultivate healthy eye behaviour among primary school students and reduce the incidence of myopia among them.

Chronic obstructive pulmonary disease(COPD)is a group of lung diseases characterized by persistent airflow limitation, often accompanied by chronic hypoxia. This chronic hypoxia can lead to structural and functional changes in the walls of blood vessels throughout the body, causing vascular injury and altered vascular reactivity. The retina and choroid are key ocular structures with rich blood supply and are particularly prone to microstructural changes due to ischemia and hypoxia. Optical coherence tomography(OCT), an ideal tool for observing these microstructural changes, serves as a non-invasive method for assessing retinal microstructures and microvascular pathology. Currently, there is a lack of comprehensive reviews summarizing OCT-based morphological changes in the eyes of COPD patients. This paper provides an in-depth review of existing studies on ocular OCT in COPD patients, focusing on structural and blood flow changes in the retina and choroid. The primary goal of this review is to summarize the impact of COPD on ocular microstructures, explore the underlying mechanisms of these morphological changes, and offer new perspectives for assessing eye diseases in COPD patients.

ObjectiveTo investigate the application of endoscopy in obtaining the great saphenous vein （GSV） during coronary artery bypass grafting （CABG） and explore the learning curve， with a particular focus on common challenges encountered during the learning process and their impact on early clinical outcomes. MethodsA retrospective analysis was conducted on clinical data from 83 patients who underwent off-pump CABG with endoscopic GSV harvesting at the First Affiliated Hospital of Zhengzhou University from July 2013 to April 2014. Patients were categorized into four groups based on the chronological order of their hospitalization： Group A （novice group， n=20）， Group B （proficient group， n=20）， Group C （progressive group， n=20）， and Group D （mature group， n=23）. Differences in perioperative and midterm follow-up outcomes among the groups were analyzed to determine the learning curve period. ResultsThe study population had a mean age of （60.22±8.06） years and a mean body weight of （69.77±11.66） kg. Comorbidities included hypertension （24 cases）， diabetes （26 cases）， and subacute cerebral infarction （14 cases）. The novice group exhibited significantly shorter GSV length-to-harvest time ratio relative to the other three groups （P<0.001） and a significantly higher incidence of main vein damage （P=0.006）. However， there was no statistically significant difference in graft patency at the 1-year follow-up. ConclusionThorough and reliable technical training in endoscopic GSV harvesting is essential to minimize vascular injury caused by novice operators. Approximately 20 cases of hands-on experience and a careful self-analysis of procedural challenges are likely required to achieve proficiency in GSV harvesting.

ObjectiveTo identify the pharmacodynamic material basis of Ruyi Zhenbaowan in relieving neuropathic pain by integrating the calculation of biological network proximity and pharmacokinetic characterization. MethodThe interaction network of "drug candidate target-related gene of disease" was constructed by Cytoscape 3.8.2， and the average shortest path value of each drug putative target acting on neuropathic pain-related genes in this network was calculated by Pesca 3.8.0 tool so as to evaluate the network proximity between them， and screen prescription candidate targets with strong intervention efficiency and their corresponding potential effect components. After that， plasma and cerebrospinal fluid samples were collected from rats after administration of Ruyi Zhenbaowan at set time points， and the contents of potential effect components in samples was quantified by ultra performance liquid chromatography-quadrupole-ion trap mass spectrometry（UPLC-Q-TRAP/MS）， and drug concentration-time curves were plotted， then the pharmacokinetic parameters were calculated by DAS 2.1.1. ResultBy evaluating the network proximity between candidate targets and neuropathic pain-related genes in the interaction network， a total of 40 putative targets of Ruyi Zhenbaowan with strong intervention effects on neuropathic pain-related genes， such as estrogen receptor 1（ESR1）， cyclic adenosine monophosphate（cAMP）-dependent protein kinase catalytic subunit alpha（PRKACA） and protein kinase B1 （Akt1）， and 10 corresponding potential effect components， such as glycyrrhizic acid and betulinic acid， were obtained. Pharmacokinetic characterization showed that among the 10 potential effect components， gallic acid， apigenin-7-O-glucuronide， glycyrrhizic acid and apigenin were well absorbed and metabolized in plasma and cerebrospinal fluid， with long onset time and good bioavailability. ConclusionFrom the perspective of efficacy-target-constituent-pharmacokinetic， this study analyzes the main effective materials of Ruyi Zhenbaowan， such as glycyrrhizic acid， gallic acid， apigenin-7-O-glucuronide and apigenin， which have a high exposure in plasma or cerebrospinal fluid and have a strong intervention effect on neuropathic pain. The related results provide reliable experimental evidences for clarifying the material basis and developing quality standards of Ruyi Zhenbaowan.

Objective To summarize and analyze the clinical phenotypes,hereditary features and treatment and follow-up strategies of different hereditary pheochromocytoma/paragangliomas(PCC/PGL)and related syndromes.Methods Forty-four clinically diagnosed PCC/PGL patients admitted in our hospital from January 2000 to August 2022 were enrolled,and the clinical data of them and their family members were collected.Second-generation sequencing was performed on 43 patients for genetic detection,and Sanger sequencing was applied to verify the mutation of the probands and family members.Results There were 15 patients diagnosed with hereditary PCC/PGL,including 7 cases of von Hippel-Lindau(VHL)syndrome,3 cases of multiple endocrine neoplasia type 2(MEN2),and 5 cases of familial paraganglioma syndrome.Seven VHL syndrome families were diagnosed as VHL2A(c.500G＞A),VHL2B(c.239G＞T and c.444_457del),and VHL2C(c.293A＞G)according to their clinical manifestations.All probands received surgical treatment,and 2 cases of recurrent PCC and the patients with multiple renal cancer also received targeted therapy with sunitinib.Three MEN2 families carried c.1901G＞C,c.1832G＞A,and c.1901G＞A missense mutations,respectively,and were diagnosed with MEN2A clinically.All of them underwent adrenalectomy and thyroidectomy,including one for preventive thyroidectomy.Among the 5 familial paraganglioma syndrome families,4 patients carried SDHB mutations(SDHB:c.343C＞T,c.541-2A＞G,c.575G＞A,c.268C＞T)and 1 patient carried an SDHD mutation(SDHD:c.337_340del).Sporadic retroperitoneal PGL were most common.Conclusion More than 1/3 of PCC/PGL patients carry germline gene mutations,showing obvious genotype-phenotype correlation.Genetic diagnosis technology plays an important guidance role for clinical precision treatment and follow-up,and genetic counseling.

Objective:To investigate the therapeutic effect difference between first-line treatment with epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKI) and chemotherapy in non-small cell lung cancer (NSCLC) patients with epidermal growth factor receptor (EGFR) rare mutation.Methods:A retrospective case-control study was performed. Data of NSCLC patients with rare EGFR mutation who were treated in Shanxi Province Cancer Hospital from January 2013 to October 2019 were retrospectively analyzed. EGFR mutations in living tissues or blood were detected by using amplification refractory mutation system-polymerase chain reaction (ARMS-PCR) before first-line treatment. According to first-line treatment methods,they were divided into EGFR-TKI treatment group and chemotherapy group. Objective remission rate (ORR) and disease control rate (DCR) of both groups were compared. Kaplan-Meier method was used to draw progression-free survival (PFS) and the overall survival (OS) curves. Log-rank test was used for comparison among groups. Single-factor and multi-factor Cox proportional risk models were used to analyze the influencing factors of PFS and OS.Results:A total of 169 patients with EGFR rare mutations were included, and the age [ M (IQR)] was 63 years (12 years); there were 96 cases (56.8%) < 65 years and 73 cases (43.2%) ≥65 years; 70 (41.4%)males and 99 (58.6%) females; 55 cases (32.5%) had EGFR G719X mutation,45 cases (26.6%) had L861Q mutation, 17 cases (10.1%) had S768I mutation, and 52 cases (30.8%) had complex mutation; 55 cases (32.5%) received the first-line chemotherapy and 114 cases (67.5%) received the first-line EGFR-TKI treatment. In the chemotherapy group, ORR was 36.4% (20/55) and DCR was 85.5% (47/55); in EGFR-TKI treatment group, ORR was 72.8% (83/114) and DCR was 90.4% (103/114). The ORR of EGFR-TKI treatment group was higher than that of chemotherapy group ( χ2 = 20.70, P = 0.001), and there was no statistically significant difference in DCR between two groups ( χ2 = 1.76, P = 0.184). Subgroup analysis showed that ORR in EGFR-TKI treatment group with G719X, L861Q and complex mutations was higher than that of the corresponding mutations in chemotherapy group, and the differences were statistically significant (all P < 0.05), while there were no significant differences in DCR among subgroups (all P > 0.05). The median PFS time was 9.7 months (95% CI: 6.0-13.4 months) and 3.8 months (95% CI: 3.1-7.1 months), respectively in EGFR-TKI treatment group and chemotherapy group, and there was a statistically significant difference in PFS between the two groups ( P < 0.001). The median OS time was 25.6 months (95% CI: 18.0-37.9 months) and 31.7 months (95% CI: 18.0-42.8 months), respectively in EGFR-TKI treatment group and chemotherapy group, and there was no statistically significant difference in OS between the two groups ( P = 0.231). Multivariate Cox regression analysis showed that brain metastasis [with vs. without: HR = 2.306, 95% CI: 1.452-3.661, P < 0.001] and the first-line treatment methods (EGFR-TKI vs. chemotherapy: HR = 0.457, 95% CI:0.317-0.658, P < 0.001) were independent influencing factors for PFS of NSCLC patients with EGFR rare mutation; brain metastasis (with vs. without: HR = 2.087, 95% CI: 1.102-3.953, P = 0.024; unknown vs. without: HR = 2.118,95% CI: 1.274-3.520, P = 0.004) were independent influencing factors for OS of NSCLC patients with EGFR rare mutation. Conclusions:Compared with the first-line chemotherapy, EGFR-TKI first-line treatment could improve objective remission and PFS of NSCLC patients with EGFR rare mutation, while no OS benefit is observed.
