ABSTRACT

OBJECTIVE To investigate the preventive effect of cucurbitacin B (CB) on sepsis-induced acute lung injury (ALI) and its mechanism. METHODS The mice were divided into control group, model group, dexamethasone group (positive control, 2 mg/kg), CB low-dose and high-dose groups (25, 50 mg/kg). Each group was given relevant medicine intraperitoneally, once a day, for 3 consecutive days. Twenty-four hours after the last administration, those groups were given lipopolysaccharide (10 mg/kg) intraperitoneally to establish sepsis-induced ALI model (finally, 8 mice per group were included in the experiment), except for control group. Twenty-four hours after medication, blood routine indicators (total white blood cell count, neutrophils count, lymphocytes count), lung function indicators (total lung resistance, pulmonary outflow resistance, lung dynamic compliance, peak expiratory flow rate, and maximum ventilation volume), dry wet ratio of lung tissue were measured in each group. The lung tissue level of myeloperoxidase (MPO), and the serum levels of tumor necrosis factor-α (TNF-α), interleukin 1β (IL-1β), IL-6, superoxide dismutase (SOD) and malondialdehyde (MDA) were all detected. The pathological changes of lung tissue were observed; immunohistochemistry was used to detect the positive expression of phosphorylation signal transducer and activator of transcription 3 (p-STAT3) in the lung tissue. Western blot assay was used to detect the expressions of proteins related to IL-6/JAK2/ STAT3 signaling pathway in the lung tissue. RESULTS Compared with control group, total pulmonary resistance, pulmonary flow resistance, dry wet ratio of lung tissue, the total white blood cell count, neutrophils count, lymphocytes count of whole blood, the lung tissue level of MPO and serum levels of MDA, IL-6, IL-1β and TNF-α, the p-STAT3 protein optical density value, the protein expressions of IL-6 and IL-6 receptor, and the phosphorylation levels of JAK2 and STAT3 protein were increased significantly in the model group (P<0.01), while lung dynamic compliance, peak expiratory flow rate, maximum ventilation volume and serum level of SOD were decreased significantly (P<0.05 or P<0.01). Pulmonary tissue showed alveolar collapse and infiltration of inflammatory cells. Compared with the model group, the above indexes of mice were reversed significantly in dexamethasone group and CB groups (P<0.05 or P<0.01), the pathological damage of lung tissue was reduced. CONCLUSIONS CB can prevent sepsis-induced ALI by inhibiting the activity of Δ 基金项目遵义市科技计划项目(No.202252) IL-6/JAK2/STAT3 signaling pathway and relieving *第一作者主治医师。研究方向:重症医学。E-mail:fjuanxui@ 163.com inflammatory reactions. # 通信作者 主任医师。研究方向:儿童呼吸系统疾病诊断与治

ABSTRACT

Objective To investigate the predictive value of systemic immune-inflammation index(SII)and N-terminal pro-brain natriuretic peptide(NT-proBNP)level in elderly patients with acute ST-segment elevation myocardial infarction(STEMI)developing contrast-induced acute kidney injury(CIAKI)after PCI.Methods A total of 1085 elderly STEMI patients undergoing emergency PCI in the Affiliated Hospital of Xuzhou Medical University from January 2018 to March 2023 were consecutively recruited as a training set,and another 287 elderly STEMI pa-tients receiving emergency PCI in the East Branch of the Affiliated Hospital from January 2021 to June 2023 were included as a verification set.According to the diagnostic criteria of CIAKI,they were divided into CIAKI group(n=95)and non-CIAKI group(n=990).Based on the results of restricted cubic spline(RCS)analysis,the patients from the training set were assigned into low-risk subgroup(n=292),moderate-risk group(n=515)and high-risk group(n=278).Multivari-ate logistic regression analysis was used to analyze the independent risk factors of CIAKI in elder-ly STEMI patients after PCI,and ROC curve was plotted to analyze the predictive value of combi-nation of SII and NT-proBNP.The risk of CIAKI was compared among the patients at different risk grades.Results Age,SII,baseline serum creatinine,NT-proBNP,fasting blood glucose and use of diuretics were independent risk factors for CIAKI after primary PCI in elderly STEMI patients(P<0.05,P<0.01).The AUC value of SII combined with NT-proBNP in predicting CIAKI was 0.801(95%CI:0.761-0.842,P<0.01),with a sensitivity of 83.2%and a specificity of 67.5%,both superior to that of SII or NT-proBNP alone.RCS analysis revealed an increased risk of CIAKI at SII ≥1084.97 × 109/L and NT-proBNP ≥296.12 ng/L.The incidence of CIAKI was increased with the increase of risk grades(1.71%vs 6.41%vs 20.50%).Conclusion SII and NT-proBNP are independent risk factors for CIAKI after emergency PCI in elderly STEMI pa-tients.And their combination has better predictive value for CIAKI.

ABSTRACT

Objective To provide reference for the development of prevention and control strategies for HIV/AIDS cases aged 50 and above in Yichang city from 2013 to 2020 by epidemiological characteristics anaylsing. Methods Descriptive epidemiological method was used to analyze the epidemic situation and epidemiological data. Results A total of 1 126 HIV/AIDS cases were reported during the monitoring period, and 296 cases were 50 years old and above, accounting for 26.29%. The proportion of cases aged 50 years and above to the total number of cases and the annual reported incidence rate both showed an upward trend (P<0.01). The cases were mainly male (74.66%), and the older the age, the greater the proportion of males (P=0.02). The age of confirmed cases is mainly concentrated in 50-59 years (68.58%), of which 49.66% were married and 74.32% were at junior high school and below. Sexual contact (accounting for 99.66%) was the main route of infection, the proportion of non-marital heterosexual sex was relatively high, especially in female cases (accounting for 74.67%). Those who had been infected for more than 8 years accounted for 48.75%, and the proportion of infected age ≥50 years in the total number of cases showed an upward trend. Cases were found mainly from medical institutions (74.66%). Conclusion The HIV/AIDS epidemic situation of people aged 50 and above in Yichang City was relatively severe and has became a key population for prevention and control. Targeted and effective prevention and control measures should be taken to reduce the harm of AIDS to the population.

ABSTRACT

Hip fractures are among the most common fractures in the elderly, presenting to be a leading cause of disability and mortality. Surgical treatment is currently the main treatment method for hip fractures. The incidence of perioperative malnutrition is increased after hip fractures in the elderly due to the comorbidities, decreased basal metabolic rate, accelerated protein breakdown, weakened anabolism and surgical stress. However, malnutrition not only increases the incidence of postoperative complications, but also leads to increased mortality, indicating an important role of perioperative nursing management of nutrition for the elderly patients with hip fractures. At present, there still lacks scientific guidance and application standards on perioperative nursing management of nutrition for the elderly patients with hip fractures. Therefore, the Orthopedic Nursing Committee of Chinese Nursing Association and the Editorial Board of Chinese Journal of Trauma organized relevant experts to formulate the Expert consensus on perioperative nursing management of nutrition for elderly patients with hip fractures ( version 2023) according to evidence-based medical evidences and their clinical experiences. Fourteen recommendations were made from aspects of nutrition screening, nutrition assessment, nutrition diagnosis, nutrition intervention and nutrition monitoring to provide guidance for perioperative nursing management of nutrition in elderly patients with hip fractures.

ABSTRACT

Colorectal cancer is a common malignant tumor in gastrointestinal tract. Its onset and development are associated with its own characteristics as well as the tumor microenvironment (TME) in which tumor-associated macrophages (TAMs) are the most abundant immune cells. After being recruited to the tumor site and stimulated by different signals in TME, TAMs can grow into two different subtypes, namely M1 and M2. TAMs are mainly manifested as M1 macrophages in the early stage of colorectal cancer, mediating the immune response to inhibit tumor growth. In the late stage, TAMs mainly grow into M2 macrophages, showing the ability to suppress immunity, stimulate the proliferation of tumor cells and tumor angiogenesis, and promote the invasion and metastasis of tumor cells. It has been found that intervention in TAMs polarization can regulate its relationship with the onset and development of colorectal cancer.

ABSTRACT

Objective:To compare the application effect of whole-process seamless nursing and conventional nursing in the perioperative period of ankylosing spondylitis (AS) with kyphosis complicated by cervical spine fracture.Methods:A retrospective cohort study was conducted to analyze the clinical data of 64 patients with AS with kyphosis complicated by cervical spine fracture admitted to Henan Provincial People′s Hospital from April 2017 to December 2022, including 37 males and 27 females, aged 27-73 years [(49.8±14.6)years]. There were 43 patients with vertebral fractures and 21 with intervertebral space fractures. All patients underwent reduction and fixation or correction and fixation. Thirty-two patients admitted from April 2017 to August 2019 received conventional care (conventional nursing group), and 32 patients admitted from September 2019 to December 2022 received whole-process seamless care (seamless nursing group). The two groups were compared concerning the visual analog scale (VAS) before, at 12 hours, 24 hours, 1 month, 3 months after surgery and at the last follow-up, the American Spinal Injury Association (ASIA) score before surgery, at 1 and 3 months after surgery and at the last follow-up, the health survey questionnaire (SF-36) score and patient satisfaction score before surgery and at the last follow-up, as well as the incidence of postoperative complications.Results:All patients were followed up for 6-12 months [(9.8±3.2)months]. There was no statistical difference in preoperative VAS between the two groups ( P>0.05). The values of VAS in the seamless nursing group were (3.9±1.9)points, (4.2±0.7)points, (2.7±0.9)points, (2.6±0.6)points, and (1.7±0.8)points at 12 hours, 24 hours, 1 month, 3 months after surgery and at the last follow-up, respectively, lower than those of the conventional nursing group [(5.7±1.2)points, (5.8±1.1)points, (3.6±1.2)points, (3.2±1.1)points, and (2.4±1.0)points] ( P<0.05 or 0.01). The VAS of the seamless nursing group at 12 hours, 24 hours, 1 month, 3 months after surgery and at the last follow-up was lower than that before surgery (all P<0.05). The VAS at 1 and 3 months after surgery and at the last follow-up was lower than those before and at 12, 24 hours after surgery and the VAS at the last follow-up was lower than those at 1, 3 months after surgery (all P<0.05). The differences among VAS of the conventional nursing group before and at 12, 24 hours after surgery were statistically insignificant (all P>0.05). The VAS of the conventional nursing group at 1 and 3 months after surgery and at the last follow-up was lower than those before surgery and at 12, 24 hours after surgery and the VAS at the last follow-up was lower than those at 1, 3 months after surgery (all P<0.05). There was no statistically significant difference in VAS of the two groups between 12 hours and 24 hours after surgery, and between 1 month and 3 months after surgery (all P>0.05). There was no significant difference in the ASIA scores before surgery between the two groups ( P>0.05). There were significant improvements in ASIA scores in the seamless nursing group at 1, 3 months after surgery and at the last follow-up compared with those of the conventional nursing group ( P<0.05). There were no statistically significant differences in preoperative SF-36 score and patient satisfaction score between the two groups (all P>0.05). At the last follow-up, the SF-36 score and patient satisfaction score of the seamless nursing group were (47.4±6.2)points and (99.5±1.2)points, respectively, which were higher than those of the conventional nursing group [(42.2±7.3)points and (98.1±1.6)points] (all P<0.05). At the last follow-up, the SF-36 score and patient satisfaction score of the seamless nursing group were higher than those before surgery (all P<0.01). The SF-36 score of the conventional nursing group was higher than that before surgery ( P<0.01), but there was no significant difference in patient satisfaction score ( P>0.05). The incidence of postoperative complications in the seamless nursing group was 6.3% (2/32), lower than that of the conventional nursing group [25.0% (8/32)] ( P<0.05). Conclusion:For AS with kyphosis complicated by cervical spine fracture, whole-process seamless nursing is associated with alleviated postoperative pain, improved spinal nervous function, quality of life and degree of satisfaction, and reduced incidence of complications compared with the conventional nursing.

ABSTRACT

Objective:To analyze potential roles of mechanical stress in the formation of plantar melanoma.Methods:A retrospective analysis was conducted on 129 cases of plantar melanoma in Xiangya Hospital, Central South University between 2014 and 2021, and the distribution and clinical characteristics of plantar melanoma were analyzed. The goodness-of-fit test was used to compare the distribution of plantar melanoma between weight-bearing areas (the toes, forefoot, lateral midfoot, heel) and non-weight-bearing areas of the foot (the arch) , while t test, Fisher′s exact test and Wilcoxon rank sum test were used to analyze differences in clinicopathological characteristics of plantar melanoma between weight-bearing areas and non-weight-bearing areas of the foot. Results:Among the 129 patients with plantar melanoma, 66 (51.2%) were males and 63 (48.8%) were females, and their age at onset was 60.6 ± 13.1 years. Plantar melanoma mostly occurred on the heel (65 lesions, 1.31 lesions per square centimeter) , followed by the forefoot (31 lesions, 0.41 lesions per square centimeter) , the bottom of the toes (15 lesions, 0.43 lesions per square centimeter) , lateral midfoot (11 lesions, 0.38 lesions per square centimeter) and the arch of foot (7 lesions, 0.16 lesions per square centimeter) . The goodness-of-fit test showed that melanoma was more prone to occur in the weight-bearing areas than in the non-weight-bearing areas ( χ2 = 66.59, P < 0.001) ; compared with the arch of foot, a higher incidence density was observed in the heel and forefoot ( χ2 = 38.29, 5.23, P < 0.001, = 0.022, respectively) . There were no significant differences in the gender ratio, age and occupation of patients, prevalence rates of left/right foot involvement, Breslow thickness, ulceration status, Clark grades, lymph node metastasis rate, and stages between melanomas in the weight-bearing areas and those in non-weight-bearing areas (all P > 0.05) . Conclusion:Plantar melanoma was more prone to occur in the weight-bearing areas than in the non-weight-bearing areas, suggesting that mechanical stress may be related to the occurrence and development of melanoma.

ABSTRACT

Objective To analyze the changes of CD4+ T cell numbers at different periods of antiviral therapy in HIV-infected and AIDS patients (HIV/AIDS) in Yichang City. Methods The relevant information was retrieved from the National AIDS Comprehensive Prevention Information System-Antiretroviral Treatment Management Database. Changes in the number of CD4+ T cells were analyzed in HIV/AIDS patients who started receiving highly active antiretroviral therapy (HAART) and continued the treatment for 3 years from January 1, 2003 to December 31, 2017 in Yichang. Results The number of CD4+T lymphocytes in 550 HIV/AIDS cases increased significantly at various time points within 3 years after treatment, and increased with the increase of treatment time(F=100.20,P<0.001). The CD4+T cell counts of different baseline level groups were statistically different before and after treatment(F=8.57,P<0.01). The CD4+ T cell counts of patients who started treatment at age of 15-30 years old increased faster than those who started treatment at age of over 30 years old(F=1.27,P<0.05). Conclusion HAART has a significant effect on the increase of CD4+T cells, and the early treatment is more effective. Early detection, diagnosis and treatment should be promoted, and anti-viral treatment should be actively carried out.

ABSTRACT

Objective@#To explore sex differences between weight and systolic blood pressure (SBP) changes among school-age children and adolescents in Beijing, and to provide a basis for priority intervention to control the rapid growth of body weight and blood pressure.@*Methods@#Anthropometric measurement data of 70 288 children and adolescents from primary and high schools in Shunyi District were collected from 2009 to 2018, and a longitudinal dataset with complete data related to weight and BP after individual data linkage was compiled. The age-specific weight and SBP growth rates were calculated, and a linear mixed-effects model was used to identify sex differences in chronological growth rates.@*Results@#Weight and SBP increased with age in both boys and girls, and the mean weight and SBP were higher in boys than in girls across all age groups. The result of the linear mixed-effects model indicated apparent sex differences in weight and SBP growth rates, with an age and sex interaction term(β=-0.35, -0.40, P<0.01). The age at peak weight velocity (PWA) was 12 years old and the age at peak SBP velocity was 13 years old in boys, which occurred one and three years later than for girls, respectively. In addition, the peak weight and SBP velocity were higher in boys than in girls. The curves of the SBP growth rate adjusted for the PWA, showed that the peak SBP velocity occurred two years before PWA and the second peak SBP velocity occurred at the PWA, which indicated "double peaks" in both boys and girls. The SBP growth rate was always higher in boys than in girls, and the rates declined after PWA.@*Conclusion@#Sex differences in weight and SBP growth rates were persistent and obvious in school-age children and adolescents in Beijing and the change in SBP was highly time synchronized with the increase in weight.

ABSTRACT

Objective@#To explore differences in the detection rate of elevated blood pressure (BP) in children aged 6-8 years old, and to verify the apparent existence of white-coat hypertension (BP) in children.@*Methods@#Based on census data(PROC), and three subsequent BP readings were taken during follow-ups which were carried out from October 2018 to June 2019. A total of 1 785 children were included in the present study. Using updating blood pressure reference for Chinese children aged 3-17 years, compared the BP detection rate at baseline, at the first follow-up, and the average value of the last two BP readings. Fluctuations in the detection rate of elevated BP in children at different time-points were analyzed.@*Results@#The detection rates of the three elevated BP measurements of 6-8-year-old children were 57.65%, 25.88% and 15.46%, respectively, and the detection rate was higher among boys than girls. The detection rate of baseline BP was higher than that of the first follow-up BP measurements and the average of the last two BP measurements(P<0.01). Given the agreement in the diagnosis of high SBP, high DBP, high BP at baseline, and the average of the last two follow-up BP measurements, elevated BP at baseline was the lowest among the three groups and SBP was higher than DBP.@*Conclusion@#Blood Pressure fluctuations might be caused by transient tension that was experienced during the baseline BP measurement and during the first of the three follow-ups. Therefore, the average value of last two BP measurements may better reflect the real BP level in children.

ABSTRACT

Objective:To discuss the application effect of enhance recovery after surgery (ERAS) combined with system nursing in patients with thoracolumbar fracture accompanied by nerve injury.Methods:A retrospective case-control study was conducted to analyze the clinical data of 84 patients with bilateral thoracolumbar fractures accompanied by nerve injury admitted to Henan Provincial People's Hospital from August 2017 to January 2020. All patients were treated with posterior thoracolumbar spinal canal decompression, bone grafting and internal fixation. There were 55 males and 29 females, aged 36-49 years [(43.2±5.2)years]. The injury segments were located at T 10-T 11 in 6 patients, T 11-T 12 in 38, T 12-L 1 in 31, and L 1-L 2 in 9. According to the Frankel classification of neurological function, 19 patients were rated as grade A, 22 grade B, 38 grade C, and 5 grade D. A total of 42 patients were treated by ERAS combined with system nursing (ERAS group), and 42 patients by routine rehabilitation nursing (routine nursing group). The hospitalization time, incidence of perioperative complications, and patients' satisfaction with nursing work were recorded. The visual analogue scale (VAS) and Oswestry disability index (ODI) were evaluated at postoperative 1 week and 3 months. The Frankel classification of neurological function and the MOS item short from health survey (SF-36) score were measured at postoperative 3 months. Results:All patients were followed up for 3-4 months [(3.2±1.7)months]. The hospitalization time in ERAS group was (10.9±1.6)days, significantly shorter than (14.4±1.2)days in routine nursing group ( P<0.05). The incidence of perioperative complications in ERAS group was 10%(4/42), significantly shorter than 29%(12/42) in routine nursing group ( P<0.05). The satisfaction rates in ERAS group and routine nursing group were 93%(39/42) and 76%(32/42), respectively ( P<0.05). At 1 week and 3 months after operation, the VAS in ERAS group [(1.7±0.4)points, (1.2±0.3)points]was significantly lower than those in routine nursing group [(4.8±0.9)points, (3.1±0.7)points]( P<0.05). At 1 week and 3 months after operation, the ODI in ERAS group [(13.5±1.8)points, (10.3±1.4)points] was significantly lower than those in routine nursing group [(17.9±2.0)points, (15.6±2.1)points]( P<0.05). At 3 months after operation, according to the Frankel classification, there were 2 patients with grade A, 9 with grade B, 13 with grade C, 13 with grade D and 5 with grade E in ERAS group, and there were 8 patients with grade A, 8 with grade B, 12 with grade C, 10 with grade D, and 4 with grade E in routine nursing group. The recovery rate of grade A or above in ERAS group was 95%(40/42), significantly higher than 81%(34/42) in routine nursing group ( P<0.05)]. At 3 months after operation, the SF-36 score in ERAS group was better than that in routine nursing group ( P<0.05). Conclusion:For patients with thoracolumbar fracture accompanied by nerve injury, ERAS combined system nursing can shorten the hospitalization time, reduce perioperative complications, improve patients' satisfaction, reduce pain, promote the recovery of nerve function, and improve the quality of life.

ABSTRACT

Gliomas are the most common primary intracranial neoplasms among all brain malignancies, and the microtubule affinity regulating kinases (MARKs) have become potential drug targets for glioma. Here, we report a novel dual small-molecule inhibitor of MARK3 and MARK4, designated as PCC0208017. PCC0208017 strongly inhibited kinase activity against MARK3 and MARK4, and strongly reduced proliferation in three glioma cell lines. This compound attenuated glioma cell migration, glioma cell invasion, and angiogenesis. Molecular mechanism studies revealed that PCC0208017 decreased the phosphorylation of Tau, disrupted microtubule dynamics, and induced a G2/M phase cell cycle arrest. In an glioma model, PCC0208017 showed robust anti-tumor activity, blood-brain barrier permeability, and a good oral pharmacokinetic profile. Molecular docking studies showed that PCC0208017 exhibited high binding affinity to MARK3 and MARK4. Taken together, our study describes for the first time that PCC0208017, a novel MARK3/MARK4 inhibitor, might be a promising lead compound for treatment of glioma.

ABSTRACT

Objective@#To investigate the expression of type Ⅰ collagen α1 chain protein (COL1A1) in triple negative breast cancer (TNBC), and its relationship with clinicopathological features and prognosis of TNBC.@*Methods@#A total of 148 TNBC specimens were collected from the Affiliated Cancer Hospital of Xinjiang Medical University from 2013 to 2015. The mRNA expression of COL1A1 was detected by fluorescence quantitative RT-PCR and the protein expression of COL1A1 was detected by Western blot. The expression of COL1A1 and α-smooth muscle actin (α-SMA) in TNBC were detected by immunohistochemistry. The relationship between the expression of COL1A1 and clinicopathological parameters and prognosis of TNBC patients was analyzed.@*Results@#The mRNA and protein expression of COL1A1 in MDA-MB-231 cells were 1.696±0.486 and 0.550±0.088, respectively, which were higher than those in MCF-10A cells (1.020±0.231 and 0.350±0.083, P=0.032, P=0.046). The mRNA and protein expression of COL1A1 in TNBC tissues were 1.632 ±0.598 and 0.733 ±0.068, respectively, which were higher than those in paracancerous tissues (1.041±0.316 and 0.612±0.016, P=0.003, P=0.039). The high expression rates of COL1A1 and α-SMA in TNBC tissues were 35.8% and 56.7% respectively, which were higher than those in paracancerous tissues (16.7% and 30.0%, P=0.041, P=0.037). The expression of COL1A1 was correlated with tumor size, TNM stage, lymph node metastasis, vascular invasion and α-SMA expression (all P<0.05). The median survival time in COL1A1 high expression group was 64 months, which was lower than that in low expression group (73 months, P<0.05). Multivariate analysis of Cox proportional hazard regression model showed that COL1A1 expression was an independent influencing factor for the survival of TNBC patients (HR=3.952, P=0.004).@*Conclusion@#The high expression of COL1A1 in TNBC is an independent prognostic factor of TNBC patients.
