AIM:To investigate the current status and influencing factors of knowledge-attitude-practice in myopia prevention and control among children and adolescents in Ningbo City, thereby providing a scientific basis for formulating targeted prevention strategies.METHODS: Children and adolescents aged 6-12 years old were selected from the medical-school collaborative myopia prevention network in Ningbo City between August 2024 and May 2025 using stratified cluster sampling. Information on myopia prevention knowledge(15 items)and practice(9 items)was collected through questionnaire surveys. Logistic regression models were used to analyze factors influencing myopia occurrence in children and adolescents.RESULTS: A total of 664 children and adolescents aged 6-12 years were enrolled in this study. Participants were divided by age into three groups: 6-7 years old(n=221), 8-9 years old(n=221), and 10-12 years old(n=222). Of the 664 questionnaires distributed, 637 valid questionnaires were returned(201 from the 6-7 age group, 235 from the 8-9 age group, and 201 from the 10-12 age group), yielding an effective response rate of 95.9%. Based on myopia screening results, the non-myopic group comprised 203 participants(31.9%), including 100 males and 103 females, with a mean age of 8.82±1.98 years old. The myopic group comprised 434 participants(68.1%), including 213 males and 221 females, with a mean age of 9.10±1.95 years old. The myopia prevalence rates in the 6-7, 8-9, and 10-12 age groups were 37.8%(76/201), 71.9%(169/235), and 94.0%(189/201), respectively(P<0.001). Regarding the knowledge and practice of myopia prevention, the overall awareness rate in the non-myopic group(59.7%±9.7%)was significantly higher than that in the myopic group(48.7%±8.5%; P<0.001). Additionally, the non-myopic group scored higher on the key practice of “regular eye examinations”(4.27±0.96)compared to the myopic group(4.10±1.05; P<0.05). Logistic regression analysis indicated that age was the primary risk factor for myopia occurrence.CONCLUSION: Age is the dominant factor in the onset of myopia, and there is a phenomenon of “knowledge-practice gap”; the traditional health education model has limitations, and a precise prevention and control system based on developmental patterns should be established.

Objective To analyze the diagnosis, treatment and clinical characteristics of a patient with parotid gland metastasis of clear cell renal cell carcinoma(ccRCC)following radical nephrectomy. Methods The clinical data and diagnostic/therapeutic course of the patient were reported, and the metastasis time and treatment methods of patients with parotid metastasis of renal cancer were summarized in combination with literature. Results The 63-year-old male patient sought medical help due to a mass behind the right ear persisting for 3 months. He had undergone a right radical nephrectomy for a renal tumor 10 years ago. Preoperative computed tomography(CT)with contrast of the parotid region revealed an approximately 2.5 cm×2.1 cm round soft-tissue density lesion in the right parotid gland with slightly irregular margins. Positron emission tomography/computed tomography(PET/CT)showed an enlarged left kidney with an irregular shape and multiple round, slightly hyperdense lesion(SUVmax=7.2), suggestive of malignancy. A round, slightly hyperdense lesion(diameter 2.6 cm, SUVmax=4.2)with well-defined borders and increased radiotracer uptake was noted in the right parotid gland, indicating a hypermetabolic mass where malignancy could not be excluded. The patient subsequently underwent partial parotidectomy, advancement flap transplantation, and facial nerve dissection. Postoperative pathology revealed tumor cells with clear/eosinophilic cytoplasm and nuclear atypia, exhibiting ill-defined borders with salivary gland tissue. Immunohistochemistry was positive for PAX-8, CAⅨ, and Ki-67. During the 12-month follow-up, the patient was in good condition with no evidence of tumor recurrence or metastasis. Conclusion Parotid gland metastasis following radical nephrectomy is exceedingly rare, with no specific imaging features and clinical manifestations, and definitive diagnosis relies on pathological examination. Currently, there is no standardized treatment protocol, but complete surgical excision remains the primary therapeutic option.

Objective To explore the research hotspots and development trends in the field of cancer treatment in the past decade. Methods The CNKI and Web of Science Core Collection databases were searched for Chinese and English articles related to cancer treatment published over the last 10 years. Bibliometric research methods were employed, including keyword cluster analysis of published literature. Results A total of 45 455 Chinese articles and 866 958 English articles were retrieved. Combining the visualization analysis results and the current research dilemma of tumor treatment revealed that the current research hotspots of tumor treatment domestically and internationally can primarily focus on four key areas. In the realm of targeted therapy, efforts are directed towards the discovery of new drug targets, overcoming resistance to targeted therapy, and the development of monoclonal antibodies and antibody–drug conjugates. In the field of immunotherapy, the emphasis lies in enhancing the response rate to immune checkpoint inhibitors, determining the mechanisms behind resistance to immunotherapy, and improving the safety of treatment. The research in traditional Chinese medicine (TCM) covers evidence-based evaluation studies on TCM treatment, the identification of populations that can gain the most benefit from TCM, and strategies for improving the quality of life. In the area of novel drug development, cutting-edge technologies, such as organoid-based screening for anticancer drugs, synthetic biology, and artificial intelligence, are under investigation. Conclusion New targeted drugs, immune efficacy improvement, multidisciplinary integration, nano-delivery, and TCM innovation are the key research directions in the field of tumor therapy in the future.

ObjectiveTo investigate the clinical efficacy and potential mechanism of Shengmai Jiuxin decoction in the treatment of acute decompensated heart failure （ADHF） with the traditional Chinese medicine （TCM） pattern of Qi and Yin deficiency， Yang deficiency， and blood stasis. MethodsA total of 68 patients diagnosed with ADHF of Qi and Yin deficiency， Yang deficiency， and blood stasis type were randomly assigned to an observation group （34 cases） and a control group （34 cases）. Both groups received conventional Western medical treatment， while the observation group was additionally administered Shengmai Jiuxin decoction. Parameters compared before and after treatment included： TCM syndrome score， TCM syndrome efficacy， New York Heart Association （NYHA） functional classification， left ventricular ejection fraction （LVEF）， N-terminal pro-B-type natriuretic peptide （NT-proBNP）， six-minute walk distance （6MWD）， hypoxia-inducible factor-1 alpha （HIF-1α）， vascular endothelial growth factor A （VEGF-A）， Caspase-3， and the number of rehospitalizations for heart failure within one month after discharge. ResultsThere were no significant differences in sex， age， vital signs， or underlying diseases between the two groups. Compared with baseline， both groups exhibited significant reductions in TCM syndrome scores， NT-proBNP， and HIF-1α levels （P<0.01）， as well as significant increases in 6MWD， LVEF， VEGF-A， and Caspase-3 levels （P<0.05， P<0.01）. After treatment， the observation group showed significantly greater reductions in TCM syndrome score， NT-proBNP， HIF-1α， and Caspase-3 levels compared with the control group （P<0.05） and significantly greater increases in 6MWD， TCM syndrome efficacy， and VEGF-A levels （P<0.05）. No significant differences were observed between the groups in NYHA functional classification， LVEF， or the number of rehospitalizations for heart failure within one month after discharge. No drug-related adverse events were reported in either group during the treatment period. ConclusionShengmai Jiuxin decoction can improve cardiac function and clinical symptoms in patients with ADHF of Qi and Yin deficiency， Yang deficiency， and blood stasis type. Its mechanisms may be related to the regulation of the HIF-1 signaling pathway by modulating targets such as HIF-1α， VEGF-A， and Caspase-3.

Objective:To investigate the clinical effect of super-thin free anterolateral thigh (ALT) flap at the junction plane of superficial and deep fat of superficial fascia to repair the soft tissue defects of the foot.Methods:The clinical data of patients with foot soft tissue defects admitted to Northern Jiangsu People’s Hospital Affiliated to Yangzhou University from June 2017 to December 2022 were retrospectively analyzed. During the operation, the super-thin free ALT flap on the affected side was harvested at the junction of superficial and deep fat of superficial fascia to repair the foot wound. The donor site wound was sutured directly or repaired with full-thickness skin graft. The flap survival and complications were observed after the operation, and the operation effect was evaluated from the following five aspects. (1) The Maryland foot function score was used to evaluate the recovery of foot function. The full score was 100 points, of which 90-100 points were excellent, 75-89 points were good, 50-74 points were fair, and < 50 points were poor. (2) The Vancouver scar scale (VSS) was used to evaluate the scar condition of the foot. The total score was 0-15 points. The higher the score, the more serious the scar. (3) The cold intolerance symptom severity (CISS) scale was used to evaluate the cold tolerance of the affected foot. The total score was 4-100 points. The higher the score, the more serious the symptoms. (4) Measuring static two-point discrimination to evaluate foot sensation, the smaller the measured value, the better the sensory recovery. (5) The satisfaction of patients with foot appearance was investigated, which was divided into five grades: very satisfied, satisfied, general, dissatisfied and very dissatisfied. Descriptive analysis of the data was performed using SPSS 26.0 software.Results:A total of 13 patients with foot soft tissue defects were enrolled, including 8 males and 5 females. The mean age was 54.7 years (range, 39-70 years). There were 10 cases of left foot and 3 cases of right foot. The wound area after thorough debridement ranged from 5.5 cm ×5.0 cm to 22.0 cm ×18.0 cm. The operation time was (145.1 ± 30.6) min. The area of the flap was 6.0 cm×5.5 cm to 23.5 cm×19.0 cm, and the thickness was (5.2 ± 1.1) mm (range, 3.0- 6.5 mm). The wound at the donor site was sutured directly in 9 cases, and coverd with the abdominal full-thickness skin graft in 4 cases. After the operation, 1 patient had partial epidermal necrosis at the distal end of the flap, 1 patient had venous crisis.The flaps survived after symptomatic treatment. The remaining 11 flaps survived smoothly. The patients were followed up for 12 to 20 months, with an average of 16 months. The foot flaps were soft and free of damage, and no secondary fat reduction or plastic surgery was required. There were no complications such as wound dehiscence, skin graft necrosis, muscle hernia, and quadriceps weakness in 13 cases of donor site except for hypoesthesia caused by scar hyperplasia in 4 cases with skin graft. At the last follow-up, the Maryland foot function score was (87.4±7.3) points, of which 7 cases were excellent, 4 cases were good, and 2 cases were fair. The excellent and good rate was 11/13. The foot scar was not obvious, the VSS score was (3.2±1.2) points. The foot was more tolerant to cold and the sensory recovery was better, the CISS score was (37.5±7.1) points and the static two-point discrimination was (13.9±1.0) mm. One month after the operation, the results of patients’ satisfaction with foot appearance were as follows: 11 cases were very satisfied and 2 cases were satisfied.Conclusion:The super-thin free ALT flap is obtained at the junction plane of superficial and deep fat of superficial fascia to repair the soft tissue defect of the foot, which can optimize the operation time. The appearance and function of the foot recover well after the operation, avoiding the secondary shaping operation, reducing the damage to the donor site, and the patients are satisfied.

Objective To explore the prognostic impact and clinical application value of therapeutic plasma exchange(TPE)intervention timing and liver injury periodization in patients with exertional heat stroke(EHS).Methods Data of 127 EHS patients from the First Medical Center of the General Hospital of the People′s Liberation Army from January 2011 to December 2023 were collected,then divided into the death group and the survival group based on therapeutic outcomes and into 5 stages according to the dynamic changes of ALT,AST,TBIL and DBIL.According to propensity score matching analysis,11 patients in the survival group and 12 patients in the death group were included in the statistical analysis,and 20 of them were treated with TPE.The changes in indicators and clinical outcomes before and after TPE were observed,in order to evaluate the impact of intervention timing on prognosis.Results Among the 23 patients,14 had no liver injury or could progress to the repair phase,resulting in 3 deaths(with the mortality rate of 21.43%),while 9 patients failed to pro-gress to the repair phase,resulting in 9 deaths(with the mortality rate of 100%),with significant differences(P＜0.05).The mortality rate of the first TPE intervention before the third stage of liver injury was 23.08%(3/13),while that of interven-tion after reaching or exceeding the third stage was 85.71%(6/7),and the difference was statistically significant(P＜0.05).Conclusion TPE should be executed actively in EHS patients combined with liver injury before the third phase to lock its pathological and physiological processes,thereby improving prognosis and reducing mortality.
