With the progress of information technology and intelligent technology,the intelligent development of urine testing instruments is facing new opportunities.Using the disease cybernetics theory model to analyze the business process and current urine testing instruments of clinical urine analyzer,a generational theoretical model of urine testing instruments has been constructed,which is conducive to guiding the intelligent development direction of urine testing instruments.The study divides urine testing instruments into one to four generations of products,with the first-generation of products being operated by doctors.The second-generation products are currently available for laboratory technicians to use various urine analyzers.The third-generation products further optimize the testing process and intelligence,without the need for inspectors to operate.The fourth-generation products are unmanned and do not require sampling.It can be seen that with the development of technology,urine analysis has indeed become more convenient,but after all,various instruments have their limitations.Therefore,the establishment of a theoretical model for the generation of urine testing instruments should be applied in clinical urine testing,which can not only improve the efficiency of urine analysis but also improve its quality.

Objective: To investigate the relationship between health literacy and sports injuries among high school students with athletic specialization, so as to provide theoretical basis for the intervention of sports injury occurrence of sports special students. Methods: A total of 443 high school students with athletic specialization aged 16-18 years old from 21 urban and rural areas in Shangrao City, Ganzhou City and Nanchang City of Jiangxi Province were selected by convenient sampling method from March to April 2023, and the health literacy and sports injury incidence were investigated. The assessment of sports injury was based on the Monitoring Method of Child and Adolescent Injury, and the assessment of health literacy level was conducted using the Interactive Health Literacy Questionnaire of Chinese Adolescents. χ 2 test was used to compare the reported rate of sports injuries among the demographic and sports training groups and the correlation between health literacy and sports injuries. Binary Logistic regression analysis was used to infer the correlation between the health literacy level of high school students with athletic specialization and the occurrence of sports injuries. Results: The prevalence of sports injury was 49.4% in high school students with athletic specialization. Binary Logistic regression analysis showed that the risk of sports injury of high school students with athletic specialization with medium and low level of health literacy was significantly increased compared with high level (medium level: OR = 1.98,95% CI =1.12-3.51; low level: OR =2.08, 95% CI =1.18-3.68), high school students with athletic specialization in low level of health awareness of sports injury risk was higher than other dimensions of health literacy level (middle level: OR =2.77, 95% CI =1.48-5.19; low level: OR =2.01, 95% CI =1.04-3.88)( P <0.05). The results of stratified analysis showed that among male students with athletic specialization and students with track and field, students with moderate/low overall health literacy had a higher risk of sports injuries compared to high level students (male students: low level, OR =2.46, 95% CI =1.15-5.28; track and field: intermediate level, OR =2.17, 95% CI =1.06-4.43, low level, OR =2.09, 95% CI =1.02-4.30; P <0.05). Conclusions There is a correlation between the health literacy level of high school students with athletic specialization and the occurrence of sports injuries. Students health awareness should be improved to reduce the risk of sports injuries.

Objective:To investigate the predictive value of differential distribution of peripheral lymphocyte subsets before and after the first 131I treatment on the therapeutic response to 131I treatment in patients with papillary thyroid cancer (PTC). Methods:A retrospective study was conducted on 46 PTC patients (16 males, 30 females, age 20-77 years) who underwent total thyroidectomy and received 131I treatment between January 2021 and August 2021 in First Hospital of Shanxi Medical University. Peripheral blood lymphocyte subsets (T, B, CD4 + T, CD8 + T, natural killer (NK), helper T (Th)1, Th2, Th17, and regulatory T (Treg) cells) were measured 1-2 d before and 30 d after 131I treatment. Based on serological and imaging evidence, therapeutic response at 6-12 months post- 131I therapy was categorized as either excellent response (ER) or non-excellent response (NER). Differences of preablative stimulated thyroglobulin (psTg) and clinical baseline characteristics between two groups were assessed by using independent-sample t test, paired t test, or Mann-Whitney U test. Predictive value of lymphocyte subsets before and after 131I treatment for therapeutic response was assessed through logistic regression analysis, ROC curve analysis, and decision curve analysis (DCA). Results:In ER group ( n=33) and NER group ( n=13), most lymphocyte subsets showed different degrees of reduction 30 d after 131I treatment compared to before 131I treatment, such as T, B, CD4 + T and Th1 cells in ER group, as well as T, B, CD4 + T, Th1, Th2, Th17, and Treg cells in NER group ( t values: 2.41-9.57, all P<0.05). Before 131I treatment, NER group had significantly higher levels of psTg, Th2, Th17, and Treg cells compared to the ER group ( t values: from -3.32 to -2.48, U=29.00, all P<0.05). After 131I treatment, most of lymphocyte subsets in NER group (T, B, CD4 + T, CD8 + T, Th1 and Treg cells) showed higher trend than those in ER group but without statistical significances ( t values: from -1.12 to -0.06, all P>0.05). Th2 cells before 131I treatment (odds ratio ( OR)=25.00, 95% CI: 1.36-459.10, P=0.030) was identified as a risk factor for NER. ROC curve analysis indicated that AUCs of psTg and Th2 cells for predicting therapeutic response were 0.932 and 0.790, respectively, which was 0.958 for the combined psTg and Th2 cells. DCA showed that within the threshold probability range of 10%-60%, the curves for psTg, Th2 cells, and the combined psTg and Th2 cells were all higher than the extreme curve, suggesting good effect. Conclusions:Most lymphocyte subsets decrease to varying degrees, and NER group shows a significant decrease 30 d after 131I treatment. Th2 cells may be a risk factor for poor response to 131I treatment, providing a certain value in predicting the therapeutic response to 131I treatment.

Objective To observe the clinical efficacy of autologous hair follicle stem cell transplantation for hair restoration in patients with alopecia. Methods Ten patients with alopecia, including five with androgenic alopecia and five with seborrheic alopecia, were selected from November 2022 to May 2023. They were treated with autologous hair follicle stem cell transplantation. Data before treatment were used as the control group, and data after treatment were used as the study group. Follow-up was conducted for 3 to 8 months. The FPF scoring system was designed to collect data and evaluate the treatment effect. Results Nine patients had an improvement score of ≥7 points, and one patient had an improvement score of 2 points, with a treatment excellence rate of 90% (9/10). Compared with the total score of (2.81±0.92) points in the control group, the total score of the study group was (9.00±2.21) points, and the difference was statistically significant (P < 0.001). Conclusion Autologous hair follicle stem cell transplantation for hair restoration is safe and effective, and has a broad range of indications.

Background::Pre-operative assessment with high-resolution magnetic resonance imaging (MRI) is useful for assessing the risk of local recurrence (LR) and survival in rectal cancer. However, few studies have explored the clinical importance of the morphology of the anterior mesorectum, especially in patients with anterior cancer. Hence, the study aimed to investigate the impact of the morphology of the anterior mesorectum on LR in patients with primary rectal cancer.Methods::A retrospective study was performed on 176 patients who underwent neoadjuvant treatment and curative-intent surgery. Patients were divided into two groups according to the morphology of the anterior mesorectum on sagittal MRI: (1) linear type: the anterior mesorectum was thin and linear; and (2) triangular type: the anterior mesorectum was thick and had a unique triangular shape. Clinicopathological and LR data were compared between patients with linear type anterior mesorectal morphology and patients with triangular type anterior mesorectal morphology.Results::Morphometric analysis showed that 90 (51.1%) patients had linear type anterior mesorectal morphology, while 86 (48.9%) had triangular type anterior mesorectal morphology. Compared to triangular type anterior mesorectal morphology, linear type anterior mesorectal morphology was more common in females and was associated with a higher risk of circumferential resection margin involvement measured by MRI (35.6% [32/90] vs. 16.3% [14/86], P = 0.004) and a higher 5-year LR rate (12.2% vs. 3.5%, P = 0.030). In addition, the combination of linear type anterior mesorectal morphology and anterior tumors was confirmed as an independent risk factor for LR (odds ratio = 4.283, P = 0.014). Conclusions::The classification established in this study was a simple way to describe morphological characteristics of the anterior mesorectum. The combination of linear type anterior mesorectal morphology and anterior tumors was an independent risk factor for LR and may act as a tool to assist with LR risk stratification and treatment selection.

BACKGROUND: Postoperative chylous ascites is an infrequent condition after colorectal surgery and is easily treatable. However, its effect on the long-term oncological prognosis is not well established. This study aimed to investigate the short-term and long-term impact of chylous ascites treated with neoadjuvant therapy followed by rectal cancer surgery and to evaluate the incidence of chylous ascites after different surgical approaches. METHODS: A total of 898 locally advanced rectal cancer patients treated with neoadjuvant chemoradiotherapy followed by surgery between January 2010 and December 2018 were included. The clinicopathological data and outcomes of the patients with chylous ascites were compared with those of the patients without chylous ascites. The primary endpoint was recurrence-free survival (RFS). To balance baseline confounders between groups, propensity score matching (PSM) was performed for each patient with a logistic regression model. RESULTS: Chylous ascites was detected in 3.8% (34/898) of the patients. The incidence of chylous ascites was highest after robotic surgery (6.9%, 6/86), followed by laparoscopic surgery (4.2%, 26/618) and open surgery (1.0%, 2/192, P = 0.021). The patients with chylous ascites had a significantly higher number of lymph nodes harvested (15.6 vs. 12.8, P = 0.009) and a 3-day longer postoperative hospital stay (P = 0.017). The 5-year RFS rate was 64.5% in the chylous ascites group, which was significantly lower than the rate in the no chylous ascites group (79.9%; P = 0.007). The results remained unchanged after PSM was performed. The chylous ascites group showed a nonsignificant trend towards a higher peritoneal metastasis risk (5.9% vs. 1.6%, P = 0.120). Univariate analysis and multivariate analysis confirmed chylous ascites (hazard ratio= 3.038, P < 0.001) as an independent negative prognostic factor for RFS. CONCLUSIONS Considering the higher incidence of chylous ascites after laparoscopic and robotic surgery and its adverse prognosis, we recommend sufficient coagulation of the lymphatic tissue near the vessel origins, especially during minimally invasive surgery.

Currently, the epidemic of 2019 coronavirus disease (COVID-19) is still ongoing. The characteristics including high contagiousness, herd susceptibility and clinical phenotype diversity, made a serious influence on people’s daily life and rountine therapy for other diseases. Breast dieases are clinical common diseases. In the central epidemic area of COVID-19, Hubei province, especially Wuhan, the clinical specialists of breast diseases should consider all of the following factors comprehensively: the prevention of COVID-19, the diagnosis and treatment of breast diseases and the accessibility of medical resources. Besides, we should select the appropriate therapy and optimize treatment process so as to prevent the propagation and cross infection of COVID-19 as well as manage the breast diseases without delay. Therefore, we carried out some management proposals of the patients with breast diseases in the central epidemic area during the epidemic of COVID-19 on the basis of conventional treatment guidelines and clinical experiences. The suggestions and corrections from colleagues will be welcomed.

Objective The aim of this study was to analyze the disease burden of cirrhosis and other chronic liver diseases caused by hepatitis B in China,from 1990 to 2016,and to provide evidence for the development of related strategies.Methods Data were collected from the results of the Global Burden of Disease Study 2016 (GBD2016).We analyzed the current epidemiological patterns by calculating the prevalence,mortality,and disability adjusted life year (DALY) of cirrhosis and other chronic liver diseases,caused by hepatitis B during 1990 and 2016 in China.Results Compared with data from 1990,the number of patients and deaths with cirrhosis and other chronic liver diseases caused by hepatitis B in 2016 increased by 79.6％ and 2.4％,respectively.The prevalence increased by 49.2％,higher (50.3％) in males than that (42.3％) in females.Compared with other age groups,the increase (33.2％) of prevalence appeared the fastest,in the 15-49 age group.In males,the number of deaths and DALYs increased by 13.6％ and 2.2％,respectively.In 2016,the five top provinces on age-standardized DALY rates,appeared as Qinghai (314.6 per 100 000),Guizhou (303.1 per 100 000),Yunnan (262.4 per 100 000),Guangxi Zhuang Autonomous Region (239.6 per 100 000) and Taiwan (227.2 per 100 000).Conclusions From 1990 to 2016,the prevalence rates of hepatitis B related cirrhosis and other chronic liver diseases showed an upward trend,particularly in males and in people aged 15 to 49 years old,in China.However,the disease burden of different provinces was unevenly distributed.Based on our findings,we suggested that strategies that related to prevention and management of hepatitis B caused cirrhosis and other chronic liver diseases should be paid more attention to.
