Objective:To explore the clinical efficacy and safety of unilateral biportal endoscopic (UBE) and percutaneous transforaminal endoscopic discectomy (PTED) techniques in treating recurrent lumbar disc herniation (RLDH).Methods:This study is a retrospective cohort study. The clinical data were retrospectively collected from 68 patients who underwent surgical treatment for RLDH at Department of Mini-invasive Spinal Surgery, the Third People′s Hospital of Henan Province from June 2020 to June 2023. The patients were divided into the UBE group (38 cases) and the PTED group (30 cases) based on the surgical technique used. The drainage volume, surgery duration, and postoperative complications for revision surgeries in both groups were recorded. Visual analogue scale(VAS) and Oswestry disability index (ODI) were used to assess back pain and leg pain degrees and improvements preoperatively, 3 days postoperatively, 3 months postoperatively, and at the final follow-up. The modified Macnab criteria were used to evaluate outcomes at the final follow-up. The data comparison was conducted using independent sample t-test, repeated measures analysis of variance, χ2 test or Fisher's exact test. Results:All surgeries were successfully completed. The surgery duration in the UBE group was significantly shorter than in the PTED group, with statistically significant differences ((50.9±10.5)minutes vs.(55.9±12.5)minutes, t=1.234, P=0.001). All patients were followed up for more than 1 year, with a follow-up period of (18.1±5.6) months (range: 12 to 29 months). Both groups showed a significant reduction in VAS and ODI for back and leg pain at all postoperative time points compared to preoperative scores (all P<0.05). However, there were no statistically significant differences in VAS of low back pain, lower limb pain score and ODI score over time between the groups (all P>0.05). At the final follow-up, the UBE group had an excellent and good rate of 92.1% (35/38); the PTED group had an excellent and good rate of 86.6% (26/30)( χ2=0.727, P=0.867). One patient in the UBE group and three in the PTED group experienced cerebrospinal fluid leaks, and one patient in the PTED group experienced postoperative leg numbness; all were discharged after conservative treatment. At the final follow-up, lumbar X-rays, CT, and MRI evaluations showed no recurrence or instability at the surgical segments. Conclusions:Both UBE and PTED can achieve good clinical outcomes in the treatment of RLDH through continuous visualization. The choice of surgical method for RLDH should be more precisely tailored to the individual.

Objective:To investigate the current situation of sitting time and health literacy among high school students in China,in order to provide a basis for improving their physical and mental health levels.Methods:A stratified random cluster sampling method was used to investigate the length of sitting time and health literacy of first and second grade high school students from 31 provinces,cities,and au-tonomous regions in China(data did not include that of Hong Kong and Macao Special Administrative Re-gion,and Taiwan Province of China).The Kruskal-Wallis H method,independent sample Mann-Whit-ney U test,and regression model were used to analyze the influencing factors of sitting time and total health literacy score.Results:(1)The total score of health literacy was statistically significant(P＜0.01)in different regions,urban and rural distribution,annual family income,parents'educational background,age,and gender.(2)The length of sitting was statistically significant(P＜0.01)among multiple groups in different regions,family annual income,parental education,and gender.However,there was no statistically significant difference between groups of different ages and urban-rural distribution(P＞0.05).(3)The analysis of multiple linear regression model showed that the total score of health literacy was positively correlated with the family's annual income and the mother's education,and nega-tively correlated with the father's education and the length of sitting.Standardized regression coefficientβcomparison:Father's education(-0.32)＞family annual income(0.15)＞mother's education(0.09)＞average daily sitting time(-0.02),with father's education having the greatest impact,fol-lowed by family annual income.The length of sitting was positively related to the family's annual income and the mother's educational background,and negatively related to the total score of health literacy.Standardized regression coefficientβ comparison:Annual family income(0.14)＞education background of mother(0.13)＞total score of health literacy(-0.02),with the impact of annual family income the largest,followed by education background of mother.Conclusion:China's first and second grade high school students generally spend a long time sitting every day,and the level of health literacy is generally low.The level of health literacy and sitting time are negatively correlated with each other,and are most in-fluenced by the educational background of high school students'parents and their family economic levels.

Objective: To understand the level of health literacy and influencing factors of Chinese general high school students, so as to provide scientific evidence for health promotion of high school students. Methods: A multistage stratified cluster sampling method was used to conduct an on site survey on the health literacy status of 8 265 high school students in 31 provinces of China by using the National Health Literacy Monitoring Questionnaire from October 2018 to June 2019. SPSS 25.0 software was used to conduct one way test and multifactor Logistic regression analysis of different demographic characteristics. Results: The health literacy level of Chinese general high school students was 7.1%; the three dimensions of literacy were ranked in descending order as follows: basic skills (21.3%), healthy lifestyles and behaviors (20.5%), and basic knowledge and concepts of health (7.8%); and the literacy levels of the six categories of health issues, in descending order, were basic medical care (88.3%), health information (75.9%), safety and first aid (51.0%), infectious disease prevention (44.2%), scientific health concept (39.0%) and chronic disease prevention (5.5%). Multifactorial Logistic regression analysis showed that ethnicity, region, family residence, school type, grade level, and father s education were the factors influencing the health literacy level of Chinese high school students( OR=2.08, 0.60/0.24, 0.44, 0.71, 1.41 /0.51, 1.37, P <0.05). Conclusions The overall health literacy level of Chinese high school students is low，ethnicity, region, family residence, school type, grade level and father s education are factors influencing the health literacy level of Chinese high school students. It is recommended that all departments at all levels focus on categorized governance to improve the health literacy level of high school students, taking into account the realities and characteristics of high school students health literacy level.

To summarize the nursing experience of a pediatric patient with multiple organ burns in the abdominal cavity and liver laceration caused by a fireworks explosion.The following nursing points were implemented:immediate activation of a multidisciplinary trauma rescue team upon admission to initiate emergency measures for traumatic shock;implementation of target-oriented fluid management to expedite postoperative intestinal function recovery;active control of abdominal infection to minimize the risk of septic shock;thorough and accurate assessment was conducted to prevent postoperative complications such as gastrointestinal hemorrhage,bile-leakage,gallbladder perforation,and delayed intestinal necrosis;nutritional screening and assessment was performed to develop personalized nutritional support programs;emphasis should be placed on pain assessment to implement individualized analgesia measures;the provision of high-quality psychological support focusing on addressing psychological trauma.The child was successfully discharged 36 days after surgery and exhibited satisfactory recovery during the two-month follow-up period.

Objective: To investigate the expression of Apelin and Snail proteins in breast cancer and their relationship with the clinicopathological features and prognosis. Methods: The expression of Apelin and Snail proteins was detected by immunohistochemistry in 89 cases of breast cancer and 50 cases of mammary adenosis collected from January to June in 2008 at Fujian Cancer Hospital; the expression was correlated with the clinicopathological features and outcome of the patients. Results: Apelin and Snail were expressed in 42 cases(47.2%)and 36 cases(40.4%)of breast cancers, respectively, and the expression was higher than that of control group (P<0.01). The expression of Apelin was positively correlated with Snail (r=0.230, P<0.05). Apelin expression was associated with lymph node metastasis and TNM staging(P<0.05). Snail expression was associated with lymph node metastasis(P<0.05). Kaplan-Meier survival curve showed that the prognosis of Apelin positive group was worse than that of Apelin negative group (P<0.01). There was no significant difference in prognosis between Snail negative and positive groups (P>0.05). The prognosis of Apelin and Snail in both positive groups was worse than that of Apelin and Snail both negative groups (P<0.01). Multivariate COX regression analysis showed that Apelin and TNM staging could be used as independent prognostic factors for breast cancer (P<0.05). Conclusions Apelin and Snail are highly expressed in breast cancer, and associated with lymph node metastasis and TNM stage. There is a positive correlation between Apelin and Snail expression, which may suggest a role in breast carcinogenesis. The prognosis of breast cancer with expression of Apelin and co-expression of Apelin and Snail is poor. Therefore, Apelin may be used as an effective indicator to evaluate the prognosis of breast cancer patients.

Objective: To investigate the clinicopathologic features of microcystic, elongated and fragmented (MELF) pattern invasion of endometrial adenocarcinoma. Methods: HE and immunohistochemistry staining method were used to analysis morphologic features and immunophenotype of 72 patients of endometrial adenocarcinoma with MELF pattern invasion, and chi-square test was used to analysis the clinicopathologic features. Results: The mean age of 72 patients was 54 years (40 to 70 years). Thirty-two patients were pre-menopausal and 40 were post-menopausal. According to the FIGO staging system (2014), 32 cases(44.4%)were at stage Ⅰ, 22 cases(30.6%)at stage Ⅱ, 17 cases(23.6%)at stage Ⅲ and 1 case(1.4%) at stage Ⅳ. Microscopically, MELF invasion showed microcystic, elongated slit-like or fragmented glands in myometrium and their lining cells usually were cube or flat, as well as the single or clusters of eosinophilic tumor cells mimicking histocytes. In addition, a fibromyxoid or inflammatory stromal response was often present.Immunohistochemical staining showed that MELF invasion was positive for p16, CA125 and CA19-9, but negative for ER, PR and p53.Compared with non-MELF pattern invasion, significant differences were noted in menopause pausimenia, FIGO stages, deep invasion into myometrium, lymph metastasis, lymphovascular space invasion (LVSL), serum CA125 and CA19-9 in patients with MELF pattern invasion (all P<0.05). Conclusions MELF pattern invasion of endometrial adenocarcinoma is characterized by advanced FIGO stage, deep myoinvasion, high metastasis rate to lymph node and LVSL. Pathologists should recognize the MELF invasion and evaluate the depth of myometrium of infiltration and LVSL with special attention to the presence of MELF invasion with necessary immunohistochemistry for more accurate pathological diagnosis.
