Objective:To explore the effect of triple pre-rehabilitation strategy on improving nutritional status, negative emotions and quality of life in breast cancer patients undergoing neoadjuvant chemotherapy, so as to provide reference for clinical practice.Methods:A quasi experimental research was adopted. A total of 133 patients who underwent neoadjuvant chemotherapy for breast cancer at Gansu Provincial Cancer Hospital between December 2023 and December 2024 were recruited as research participants. Patients were stratified into the experimental group ( n = 66) and control group ( n = 67) according to their admission sequence. The control group received routine health guidance, while the experimental group was provided with a triple pre-rehabilitation strategy based on the control group. The serum albumin, body mass index, anxiety, depression scores and quality of life scores were compared between the two groups before intervention, 3 weeks after intervention and 2 weeks post-surgery. Results:Totally 64 patients in each group completed the study. The age of the experimental group was (49.50 ± 10.46) years, and that of the control group was (50.42 ± 12.50) years. All of them were females. After a 3-week intervention, the serum albumin levels in the experimental group were (42.62 ± 1.56) g/L, compared to (40.50 ± 1.31) g/L 2 weeks post-surgery. In the control group, these values were (40.98 ± 1.35) g/L and (40.00 ± 1.67) g/L, respectively. The differences between groups were statistically significant ( t = -6.38, -1.89, both P<0.05). Additionally, body mass index of the experimental group was (24.02 ± 1.35) kg/m 2 after the 3-week intervention and (23.48 ± 1.72) kg/m 2 2 weeks post-surgery, which were significantly higher than those of the control group (22.98 ± 1.72) kg/m 2 and (22.50 ± 1.31) kg/m 2, respectively ( t = - 3.81, - 3.61, both P<0.05). The anxiety scores in the experimental group were (6.00 ± 2.09) of 3 weeks after intervention and (7.00 ± 2.62) 2 weeks post-surgery, both of which were significantly lower than those in the control group (7.00 ± 2.26) and (8.00 ± 2.76), with statistically significant differences ( t = 2.60, 2.10, both P<0.05). Additionally, the depression scores in the experimental group were (5.00 ± 2.20) of 3 weeks after intervention and (6.00 ± 2.40) 2 weeks post-surgery, which were also significantly lower than those in the control group (6.00 ± 2.02) and (7.00 ± 2.09), with statistically significant differences ( t = 2.68, 2.52, both P<0.05). Furthermore, the quality of life scores in the experimental group were (94.84 ± 18.00) of 3 weeks after intervention and (84.02 ± 17.13) 2 weeks post-surgery, which were significantly higher than those in the control group (82.00 ± 18.75) and (72.03 ± 17.10), with statistically significant differences ( t = - 3.95, - 3.96, both P<0.05). Conclusions:The triple pre-rehabilitation strategy plays a crucial role in mitigating the nutritional risk for breast cancer patients undergoing neoadjuvant chemotherapy, alleviating their negative emotions, and enhancing their quality of life. This approach is anticipated to serve as a valuable reference for preoperative health guidance tailored to breast cancer patients undergoing neoadjuvant chemotherapy.

Objective:To explore the current situation and influencing factors of health literacy of postoperative lung cancer patients, so as to provide a basis for the development of relevant interventions.Methods:Using the convenient sampling method, a total of 200 postoperative lung cancer patients who came to Shanxi Provincial Cancer Hospital for follow-up from March to November 2023 were selected as the research objects. The survey was conducted using Health Literacy Management Scale (HeLMS), Family APGAR Index and Connor-Davidson Resilience Scale (CD-RISC). Multiple linear regression analysis was used to analyze the influencing factors.Results:In this study, a total of 200 questionnaires were sent out and 186 were valid, with an effective recovery rate of 93%. The total scores of HeLMS, CD-RISC and Family APGAR Index were (73.11±19.12), (48.46±10.72) and (5.07±2.82) in 186 postoperative lung cancer patients. Age, education level, complicity of other chronic diseases, psychological resilience and family care were the factors influencing health literacy of postoperative lung cancer patients ( P<0.05), which could explain 32.8% of the variation. Conclusions:Clinical medical staff should pay more attention to patients with postoperative lung cancer patients who are older, less educated and not complicated with other chronic diseases, and take certain intervention measures to improve the degree of family care and psychological resilience of patients, so as to improve the health literacy of patients.

The prevention and control of chronic and non-communicable diseases is an important public health problem in China. The general environment in the northwestern China is unique, and the health and disease status of local population is distinctive. In order to meet the urgent need for in-depth research of the causes, mechanisms and prognosis of chronic and non-communicable diseases in this area, a general population cohort in Shaanxi Province, Gansu Province and Qinghai Province, Ningxia Hui Autonomous Region and Xinjiang Uygur Autonomous Region was established during 2017-2019. A total of 117 644 general individuals aged 35-74 years in the multi-ethnic groups (Han, Hui, Uygur, Kazak and Tibetan) were recruited according to the special ecological environment, population size and ethnic distribution. The baseline information about individual exposure, environment and society were collected. More than 900 000 biological samples, including whole blood, plasma, serum and buffy coat, were collected and stored at -80 ℃ in standardized biobank. The long-term observation has started in forms of routine monitoring and active follow-up. The average age of the cohort members was 52.43 years, and 70 391 cohort members were women (59.8%). There were some differences in socio-economic status and lifestyle among different ethnic groups. Although the cohort members in different ethnic groups had similar health status, different characteristics still existed. The cohort can serve as a platform for in-depth research of the relationship between major chronic and non-communicable diseases and environment, people's lifestyle and genetic factors, and the research results can be used as important epidemiological evidence for clarifying the causes of chronic and non-communicable diseases and long-term health hazards in different ethnic groups in this area and reference for the national chronic and non-communicable disease prevention and control. This paper briefly introduces the design and practice of general population cohort in northwestern China.

Objective:To investigate the factors affecting postoperative short-term improvement of consciousness level in patients with prolonged disorders of consciousness after severe traumatic brain injury (sTBI).Methods:A case-control study was conducted to analyze the clinical data of 55 patients with prolonged disorders of consciousness after sTBI admitted to Beijing Tiantan Hospital Affiliated to Capital Medical University and Seventh Medical Center of PLA General Hospital from September 2021 to September 2022. There were 33 males and 22 females, with the age range of 13-68 years [(43.0±15.5)years]. All patients were assessed for the consciousness level using the coma recovery scale-revision (CRS-R) preoperatively and within 48 hours postoperatively. A total of 33 patients were observed in vegetative state and 22 in minimally conscious state preoperatively. The consciousness level was found to be improved in 26 patients (consciousness- improved group), but not improved in the remaining 29 patients (consciousness-unimproved group). Indicators were documented including gender, age, cause of injury, Glasgow coma score (GCS) on admission, course of injury, preoperative consciousness level, operation mode, operation time, intraoperative fluid replenishment, intraoperative urine volume, intraoperative bleeding volume, American Society of Anesthesiologists grade, analgesic regimen and sedation maintenance drugs. A univariate analysis was conducted first to assess those indicators′ correlation with postoperative short-term improvement of consciousness level in patients with prolonged disorders of consciousness after sTBI. Multivariate Logistic regression analysis was then used to determine the independent risk factors for their postoperative short-term improvement of consciousness level.Results:Univariate analysis showed that GCS on admission, course of injury, preoperative consciousness level and analgesic regimen were correlated with short-term improvement of postoperative consciousness level in patients with prolonged disorders of consciousness after sTBI (all P<0.05), whereas gender, age, cause of injury, operation mode, operation time, intraoperative fluid replenishment, intraoperative urine volume, intraoperative bleeding volume, American Society of Anesthesiologists grade and sedation maintenance drugs showed no relation to the improvement of postoperative consciousness level (all P>0.05). Multivariate Logistic regression analysis showed that the GCS ≥7 points on admission ( OR=0.06, 95% CI 0.01, 0.36, P<0.01), preoperative minimally conscious state ( OR=0.09, 95% CI 0.02, 0.40, P<0.01) and intraoperative use of Sufentanil combined with Remifentanil ( OR=0.07, 95% CI 0.01, 0.43, P<0.01) were significantly correlated with postoperative improvement of consciousness level. Conclusion:The GCS on admission (≥7 points), preoperative minimally conscious state and intraoperative use of Sufentanil combined with Remifentanil are independent risk factors affecting short-term postoperative improvement of consciousness level in patients with prolonged disorders of consciousness after sTBI.

Areca catechu L. medicinal materials and their preparations are widely used in clinical practice. Betelnut polyphenol is one of the main chemical components with antioxidant, anti-inflammatory, and antibacterial effects. With continuous increase of high altitude activities, tissue oxidative damage caused by high altitude hypoxia seriously affects the ability to work, and the studies on anti-hypoxia drugs are particularly important. Recent studies have shown that betelnut polyphenols have protective effects on oxidative stress injury caused by hypoxia via improving blood gas index of hypoxic organism, increasing superoxide dismutase glutathione catalase activity, and scavenging excessive free radicals. The effects of betelnut polyphenols against hypoxia and oxidative damage protection suggest that betelnut polyphenols can be used as potential anti-hypoxia drugs and posses clinical prospects.

Objective:To investigate the incidence rate, surgical rate and spontaneous cure of indirect inguinal hernia in children of Xinjiang region.Methods:Children, aged from 4?14 years, coming from 24 kindergartens, 18 primary schools and 9 junior middle schools of 3 countries and 5 cities in Xinjiang Uygur Autonomous Region were recruited to participate as respondents. The survey time for baseline data collection was from May 2013 to June 2014 and the retrospective cross-sectional survey was conducted. Parents of children were investigated by questionnaire, and children were examined on site. Observation indicators: (1) results of questionnaire survey; (2) illness and treatment of children involved in the study; (3) follow-up. Follow-up was conducted using telephone interview. Children who had been diagnosed and not been treated surgically at the time of questionnaire survey were followed up to detect disease progression and treatment in the past 5 years. If the symptoms of a child had disappeared during follow-up, parents of the child should accompany the child to hospital for physical examination and B-ultrasound examination to confirm the diagnosis, and then follow-up was conducted by telephone interview. The follow-up was up to January 2020. Count data were described as absolute numbers and percentages, and compari-son between groups was conducted using the chi-square test. Odds ratio and 95% confidence interval were calculated. Results:(1) Results of questionnaire survey. A total of 19 132 question-naires were distributed, and 19 132 complete questionnaires were recovered. Of the 19 132 children who completed the questionnaire survey, there were 9 670 males and 9 462 females. (2) Illness and treatment of children involved in the study. ① Incidence of indirect inguinal hernia in children with different sexes. Of the 19 132 children, 498 cases were diagnosed as indirect inguinal hernia, including 368 boys and 130 girls, with the prevalence as 3.806%(368/9 670) and 1.374%(130/9 462), respectively.

The proportion of boys and girls in children with indirect inguinal hernia was 73.896%(368/498) and 26.104%(130/498), respectively, with the ratio of 2.8:1. The prevalence of boys was higher than girls ( odds ratio=2.84, 95% confidence interval as 2.32?3.48).② Age of children at first onset. Of the 498 children with indirect inguinal hernia, 59 cases were aged 1?4 years at first onset including 54 boys and 5 girls, 264 cases were aged 5?8 years including 196 boys and 68 girls, 148 cases were aged 9?12 years including 104 boys and 44 girls, 27 cases were aged 13?14 years including 14 boys and 13 girls. There was a significant difference in the age of children at first onset between boys and girls ( χ2=17.33, P<0.05). ③ Pathogenic factors in children with indirect inguinal hernia. Of the 498 children with indirect inguinal hernia, 457 cases had complete family history and crying history, and 41 cases were missing. Family history: of the 457 children with indirect inguinal hernia who had complete family history, there were 175 cases with the family history of indirect inguinal hernia and 282 cases without the family history. Of the 478 healthy children surveyed in the same period, there were 25 cases with the family history and 453 cases without the family history. There was a significant difference in the family history between the 457 children with indirect inguinal hernia and the 478 healthy children ( χ2=515.89, P<0.05). Crying history: of the 457 children with indirect inguinal hernia who had complete crying history, there were 194 cases with obvious crying history and 263 cases without obvious crying history. Of the 496 healthy children surveyed in the same period, there were 99 cases with obvious crying history and 397 cases without obvious crying history. There was a significant difference in the crying history between the 457 children with indirect inguinal hernia and the 496 healthy children ( χ2=56.51, P<0.05). ④ Surgical treatment. Of the 498 children with indirect inguinal hernia, 233 cases underwent surgical treatment including 217 boys and 16 girls, 265 cases were followed up without surgical treatment including 151 boys and 114 girls. The surgical rate for indirect inguinal hernia in boys and girls was 58.967%(217/368) and 12.308%(16/130), respectively, showing a significant difference between them ( χ2=84.01, P<0.05). The operation ratio of boys and girls was 13.6:1, and the surgical rate of boys was higher than girls ( odds ratio=10.24, 95% confidence interval as 5.83?17.98). (3) Follow-up. All the 265 children without surgical treatment for indirect inguinal hernia were followed up for 5 years. During the follow-up, there were 142 of 151 boys with surgical treatment and 9 boys without surgical treatments, showing negative in spontaneous cure. There were 27 of 114 girls with surgical treatment and 87 girls without surgical treatment, showing 55 cases positive in spontaneous cure and 32 cases still with indirect inguinal hernia. There was a significant difference in spontaneous cure between the 151 boys and the 114 girls ( χ2=143.79, P<0.05). Conclusion:In Xinjiang region, the incidence rate and surgical rate of indirect inguinal hernia are lower in girls compared with boys, and the spontaneous cure rate is higher in girls compared with boys.

Objective:To test the reliability and validity of a multi-dimensional, quantitative video evaluation system (the Multi-dimensional system) for evaluating hand dysfunction among stroke survivors so as to provide an objective basis for its clinical application.Methods:Sixty stroke survivors with single dysfunctional hand were evaluated using the Multi-dimensional system and also using the Fugl-Meyer Upper Extremity Assessment (FMA-UE) and the Action Research Arm Test (ARAT) and in terms of their active range of hand motion (AROM-H). The Multi-dimensional system′s internal consistency, composite reliability, split-half reliability, parallel-forms reliability as well as intra- and inter-observer reliability were quantified. Its validity was tested in terms of content validity, structural validity, convergent validity and criterion validity.Results:The system′s Cronbach′s α was determined to be 0.86. Its one-dimension composite reliability was 0.939, its split-half reliability coefficient was 0.88 and its parallel-forms reliability was 0.922. The inter-evaluator reliability was between 0.965 and 0.998 [95%CI= (0.919, 0.999)], and the single evaluator ICC value was 0.973 to 0.998 [95%CI= (0.937, 0.999)]. The validity test produced a content validity index of 1, and the Pearson correlation coefficients between each sub-item and the total score were all greater than 0.60. The KMO value for structural validity was 0.882, and there was a common factor in the component matrix which reflected 60.9% of the information in the original variables. The system′s convergent validity AVE was 0.609 with Pearson correlation coefficients between the multidimensional system and the FMA-UE and ARAT both > 0.70.Conclusion:The multi-dimensional quantitative video evaluation system has good reliability and validity in the evaluation of stroke survivors with hand dysfunction.
