AIM: To explore the risk factors of macular edema in patients with diabetes cataract after surgery, and provide reference for postoperative prevention and treatment.METHODS: A total of 55 diabetes cataract patients(55 eyes)with macular edema after phacoemulsification surgery at the ophthalmology department of Jiaozhou Central Hospital of Qingdao from January 2022 to January 2024 were selected as edema group. In addition, 59 patients(59 eyes)with diabetes cataract who received the same surgical treatment but did not develop macular edema were treated as control group, and the relationship between interferon-induced protein-10(IP-10), macrophage chemotactic protein-1(MCP-1), vascular endothelial growth factor(VEGF)and postoperative macular edema was analyzed.RESULTS:Age, diabetes course, best corrected visual acuity(BCVA), glycated hemoglobin(HbA1c), creatinine, levels of IP-10, MCP-1 and VEGF in aqueous humor in the edema group were higher than those in the control group(all P<0.05). The risk factors for postoperative macular edema in patients with diabetes cataract were prolonged duration of diabetes, BCVA, increased HbA1c, increased creatinine and IP-10 in aqueous fluid, increased MCP-1 and increased VEGF(all P<0.05).CONCLUSION:Macular edema after surgical treatment in diabetes cataract patients is associated with prolonged duration of diabetes, BCVA, HbA1c, creatinine, IP-10, MCP-1, and VEGF, and clinical interventions should be given in advance.

Objective: To investigate the iodine nutrition status of children in water borne iodine excess areas in Hebei Province, so as to provide references for scientific prevention and control of water borne iodine excess hazards. Methods: From March to September each year during 2018 to 2023, a cross sectional survey was conducted in 39 water borne iodine excess counties (measured in 2017) from 5 cities (Cangzhou, Hengshui, Xingtai, Handan and Langfang) in Hebei Province. The survey included the detection of iodine content in residents drinking water, the measurement of thyroid volume in children aged 6-12, the detection of salt iodine and urinary iodine. The iodine nutrition status and water iodine distribution of 6-12 year-old children were evaluated from different perspectives such as years, gender, and age. Kruskal-Wallis H- test, Mann-Whitney U test and Chi square test were used for group comparison. Results: A total of 38 755 children were surveyed from 2018 to 2023, and 1 270 drinking water samples were tested across the province. The mass volume concentration of iodine in water showed a decreasing trend over the years ( Z= -30.87, P <0.01). Among 38 470 salt samples monitored from children s home, 24 790 were not non iodized salt, with a non iodized salt rate of 64.44%. A total of 31 989 urine samples were collected from children aged 8-10 years, with the median urine iodine was 245.94 μg/L. Comparing the results of urinary iodine in children from different years, the median urinary iodine from 2018 to 2023 were 328.0, 339.3, 267.8, 279.1, 291.3, 186.5 μg/L, respectively, with statistically significant differences ( H= 4 138.40 , P <0.01). Further pairwise comparisons showed that the median urinary iodine of children in 2023 was lower than in all other years ( Z =-51.59 to -11.41, all P <0.01). Among children aged 6-12 years, 1 150 cases of goiter were detected and the rate of goiter was 3.0%; and the goiter rates in boys and girls were 2.8% and 3.1%, with no significant difference between the sexes ( χ 2= 2.76, P >0.05). There were significant differences in the rate of goiter among different years and ages ( χ 2=324.02, 191.61, both P <0.05). Conclusions With the progress of water reform in water borne iodine excess areas of Hebei Province, children s iodine nutrition has reduced from excessive state to suitable state. It is necessary to continue to expand the coverage of water based iodine reduction projects, and strengthen the monitoring of iodine nutrition status of key populations in water borne iodine excess areas.

OBJECTIVE To analyze the use status and development trend of proton pump inhibitors(PPIs) in 33 hospitals in Wuhan, Hubei Province after the implementation of the national centralized drug procurement(NCDP) policy, and to provide reference for promoting the subsequent rational use of NCDP drugs and improving related policies. METHODS To make statistics and analysis of purchasing amount of PPIs, defined daily dose system(DDDs), defined daily dose consumption(DDDc) and utilization rate of 33 hospitals in Wuhan in 2019 and 2022. RESULTS After the implementation of the NCDP policy, the total purchasing amount of PPIs decreased by 53.6%, DDDs decreased by 15.4%, DDDc decreased by 45.2%, and the utilization rate of PPIs injectable dosage forms decreased by 12.6%. After NCDP, the highest growth rate of oral dosage forms was omeprazole(5.7%), followed by rabeprazole(5.0%), while injectable dosage forms showed a significant difference in utilization rate, with a significant decline in NCDP varieties and a significant increase in non-NCDP varieties. The overall NCDP utilization rate of PPIs in Wuhan was 64.9%, with little difference among hospitals of different grades. CONCLUSION The NCDP policy achieves the purpose of reducing the drug cost of patients and improving the accessibility of drugs, and is more optimized in the selection of dosage forms, which is in line with the policy expectations overall; but the quantity and price of PPIs in Wuhan decreased after NCDP, and highlighted a certain tendency in the selection of varieties. In the future, we still need to optimize measures to guide clinical priority in the selection of NCDP drugs, to ensure and improve the implementation of NCDP policy.

Objective:To explore the efficacy of online pulmonary rehabilitation (PR) management among community-dwelling patients with stable chronic obstructive pulmonary disease (COPD).Methods:This study was a single-center randomized controlled trail with an unblinded design. A total of 130 patients with stable COPD who visited Zhuanqiao Community Health Service Center in Shanghai Minhang District from October 2020 to March 2022 were randomly divided into study group and control group with 65 cases in each group. Both groups received conventional treatment, while patients in study group attended online rehabilitation management, including face-to-face rehabilitation instruction and multiple online guidance. Pulmonary ventilation function including forced vital capacity (FVC), forced expiratory volume in the first second (FEV 1) and percentage of forced expiratory volume in the first second to forced expiratoty volume (FEV 1%pred), modified British Medical Research Council Dyspnea Scale (mMRC), chronic obstructive pulmonary disease assessment test (CAT), score of 6 minutes walking distance (6MWD) and DOSE (dyspnea, degree of airflow obstruction, smoking status, the number of exacerbation) index were measured at baseline and after 8 weeks of rehabilitation, and compared between two groups. Results:The baseline data of the two groups were comparable. After 8 weeks of management, FVC, FEV 1, FEV 1%pred, mMRC, CAT, 6MWD and DOSE index of both groups were improved compared with the baseline level(control group: t=-7.799, -7.581, -9.010, 3.565, 9.887, -16.677, 3.795; study group: t=-12.623, -13.914, -17.644, 7.404, 22.457, -26.826, 7.968; all P<0.05). The FEV 1%pred, CAT and 6MWD in the study group were better than those in the control group ( t=-2.939, 2.277,-2.130, all P<0.05); while there were no significant differences in FVC, FEV 1, mMRC and DOSE index between the two groups( t=-0.162, -1.280, 0.925, 1.939,all P>0.05). Conclusions:The online pulmonary rehabilitation management can better improve lung function, dyspnea symptoms and exercise tolerance of patients with stable COPD, which can be used for rehabilitation training and management of community-dwelling patients.

Hypoxia is associated with the occurrence and development of many diseases in clinical settings.Cell hypoxia not only serves as a vital marker for disease advancement,but also plays a pivotal role in exacerbating the disease process,and improving tissue hypoxia may thus provide new strategies for the treatment of related diseases.Further investigation of these diseases at the cellular and molecular levels requires the establishment of a cellular hypoxia model.Current extensively employed hypoxic cell models can be categorized primarily into three types:chemical hypoxia,physical hypoxia,and glucose deprivation hypoxia models.This article reviews the various types of hypoxic cell models and scrutinizes their applications and limitations in disease research.

Objective:To explore the current status of readiness for young and middle-aged maintenance hemodialysis (MHD) patients to return to work and analyze its influencing factors, with the aim of providing reference for the evaluation and intervention of patients returning to work.Methods:From October to December 2022, convenience sampling was used to select 425 patients from six hospitals in the urban area of Yangzhou as the subject. A cross-sectional survey was conducted using the General Information Questionnaire, Readiness for Return-To-Work Scale (RRTWS), Distress Disclosure Index (DDI) and Perceived Social Support Scale (PSSS). Binary Logistic regression was used to analyze the influencing factors of returning to work.Results:Among 425 young and middle-aged patients undergoing MHD, 105 (24.7%) returned to work, of which 79 (75.2%) were in the uncertain maintenance stage and 26 (24.8%) were in the active maintenance stage. 320 did not return to work, including 148 (46.3%) in the pre-intention stage, 86 (26.9%) in the intention stage, 42 (13.1%) in the action preparation self-evaluation stage, and 44 (13.8%) in the action preparation behavior stage. Age, per capita monthly income of the family, number of comorbidities, level of self-disclosure, and level of perceived social support were factors that affected patients' readiness to return to work.Conclusions:The rate of young and middle-aged MHD patients returning to work needs to be improved. The return of patients to work is influenced by multiple factors. Medical and nursing staff should focus on patients who are old, have low per capita monthly income of the family, and have a large number of comorbidities. Targeted interventions and guidance should be provided to patients, such as self-disclosure training and improving their perceived social support, in order to increase the rate of patients returning to work rate.
