OBJECTIVE: To preliminarily investigate the effect of buccal acupuncture therapy on ameliorating postoperative pain and enhancing recovery quality among patients undergoing radical resection of gastrointestinal cancers. METHODS: Fifty-two participants were randomized at a 1:1 ratio to either the buccal acupuncture or the control group. The acupuncture protocol entailed targeting 5 predetermined acupoints [CA-2 (Upper jiao), CA-3 (Middle jiao), CA-4 (Lower jiao), CA-6 (back), and CA-7 (waist) and two adjustable acupoints [CA-1 (head) and CA-8 (sacrum)] on each side of the face. The outcomes included the Numeric Rating Scale (NRS) scores for each day within 7 days postoperatively, 15-Item Quality of Recovery Scale (QoR-15) scores, analgesics consumption during and after surgery, incidences of postoperative nausea and vomiting, and perioperative levels of interleukin-6 and glucose. Adverse events related to acupuncture were recorded. RESULTS: Of the initial 52 participants, 46 completed the study and were included in the analysis. Findings indicated that the buccal acupuncture group experienced significantly reduced resting NRS scores in post-anesthesia care unit and throughout the postoperative phase (P=0.001 and P=0.003, respectively), along with enhanced QoR-15 scores on the 3rd postoperative day (P=0.008), compared to the control group. No notable differences were identified in the remaining indicators (P>0.05). CONCLUSION Buccal acupuncture therapy demonstrated significant effectiveness in reducing postoperative pain and improving recovery quality for patients undergoing radical resection of gastrointestinal cancers, presenting a viable intervention without associated adverse outcomes.

With the growing emphasis on maternal and child oral health, the significance of managing oral health across preconception, pregnancy, and infancy stages has become increasingly apparent. Oral health challenges extend beyond affecting maternal well-being, exerting profound influences on fetal and neonatal oral development as well as immune system maturation. This expert consensus paper, developed using a modified Delphi method, reviews current research and provides recommendations on maternal and child oral health management. It underscores the critical role of comprehensive oral assessments prior to conception, diligent oral health management throughout pregnancy, and meticulous oral hygiene practices during infancy. Effective strategies should be seamlessly integrated across the life course, encompassing preconception oral assessments, systematic dental care during pregnancy, and routine infant oral hygiene. Collaborative efforts among pediatric dentists, maternal and child health workers, and obstetricians are crucial to improving outcomes and fostering clinical research, contributing to evidence-based health management strategies.

Objective To measure the distance between the lateral compression Ⅱ(LC-Ⅱ)screw guide needle and the surrounding important structures around the anterior inferior iliac spine in pelvic fractures and to locate the needle point,so as to provide anatomical reference for clinical nail placement.Methods Totally 40 adult gross specimens of embalming were implanted with LC-Ⅱ screw guide needle under the surveillance of C-arm machine,and the specimens were dissected.The shortest distance between the insertion point and the lateral femoral cutaneous nerve,femoral nerve,femoral artery,femoral vein,anterior superior iliac spine and inguinal ligament was measured.The triangle was constructed between the insertion point,anterior superior iliac spine and inguinal ligament,and the exact location of the entry point was calculated.Results The average distance between the insertion point of the male needle and the femoral vein was(50.67±7.29)mm＞the anterior superior iliac spine(43.83±7.58)mm＞the femoral artery(38.35±6.63)mm＞the femoral nerve(31.17±1.67)mm=the inguinal ligament(28.69±6.59)mm＞the lateral femoral cutaneous nerve(7.98±3.81)mm.The mean distance between the insertion point of the female needle and the anterior superior iliac spine was(45.28±7.07)mm=femoral vein(43.72±6.89)mm＞femoral artery(33.76±6.33)mm＞femoral nerve(25.66±6.46)mm=inguinal ligament(23.22±5.00)mm＞lateral femoral cutaneous nerve(8.97±4.76)mm.The projection distance of the entry point was 31.77 mm for men and 38.41 mm for women.The Angle b was 42.81°for men and 31.71° for women.Conclusion The lateral femoral cutaneous nerve is most vulnerable to injury when LC-Ⅱ screw is inserted,and the risk of injury has nothing to do with sex.The insertion point positioning method a and b made LC-Ⅱ screw placement quickly,safely and accurately,and reduced fluoroscopy time and frequency.

Objective: To explore the effects of protein powder on the bioavailability of perfluoroalkyl substances (PFASs) in blood and kidneys of rats and renal function change. Methods: Twenty-four rats of the SD strain were randomly divided into the negative control group, PFASs group and protein powder group, with 8 rats (half males and half females) in each group. PFASs included 13 perfluorocarboxylic acids (PFCAs) and 8 perfluorosulfonic acids (PFSAs), and the mixture was used as a test subject for intervention. The rats in the negative control group were given deionized water at doses of 20 mL/kg·bw, in the PFASs group were given 5 mL/kg·bw of PFASs mixtures and 15 mL/kg·bw of deionized water, and in the protein powder group were given 5 mL/kg·bw of PFASs mixtures and 15 mL/kg·bw of protein powder (0.258 g/mL). After intervention for 28 successive days, body weight and kidney mass were weighed, and the kidney volume index was calculated. Serum creatinine and blood urea nitrogen were detected by an automatic biochemical analyzer. The PFCAs, PFSAs and PFASs contents were quantified in blood and kidney using ultra-high performance liquid chromatography-electrospray tandem mass spectrometry, and the bioavailability was estimated. Results: There was no significant differences in kidney mass, kidney volume index, serum creatinine and blood urea nitrogen among the negative control group, PFASs group and protein powder group (all P>0.05). The bioavailability of blood PFCAs, PFSAs and PFASs in the protein powder group was not significantly different from the PFASs group (all P>0.05). Compared with the PFASs group, the bioavailability of PFCAs, PFSAs and PFASs were significantly increased in kidneys of male rats in the protein powder group (all P<0.05), while were not significant different in those of female rats (all P>0.05). Conclusion Protein powder at the dose of this study can significantly improve the bioavailability of PFASs in kidneys of male rats, while there no obvious effects on the bioavailability of blood PFASs and renal function.

Objective:To study the current status of longitudinal extrauterine growth restriction (EUGR) in extremely preterm infants (EPIs) and to develop a prediction model based on clinical data from multiple NICUs.Methods:From January 2017 to December 2018, EPIs admitted to 32 NICUs in North China were retrospectively studied. Their general conditions, nutritional support, complications during hospitalization and weight changes were reviewed. Weight loss between birth and discharge > 1SD was defined as longitudinal EUGR. The EPIs were assigned into longitudinal EUGR group and non-EUGR group and their nutritional support and weight changes were compared. The EPIs were randomly assigned into the training dataset and the validation dataset with a ratio of 7∶3. Univariate Cox regression analysis and multiple regression analysis were used in the training dataset to select the independent predictive factors. The best-fitting Nomogram model predicting longitudinal EUGR was established based on Akaike Information Criterion. The model was evaluated for discrimination efficacy, calibration and clinical decision curve analysis.Results:A total of 436 EPIs were included in this study, with a mean gestational age of (26.9±0.9) weeks and a birth weight of (989±171) g. The incidence of longitudinal EUGR was 82.3%(359/436). Seven variables (birth weight Z-score, weight loss, weight growth velocity, the proportion of breast milk ≥75% within 3 d before discharge, invasive mechanical ventilation ≥7 d, maternal antenatal corticosteroids use and bronchopulmonary dysplasia) were selected to establish the prediction model. The area under the receiver operating characteristic curve of the training dataset and the validation dataset were 0.870 (95% CI 0.820-0.920) and 0.879 (95% CI 0.815-0.942), suggesting good discrimination efficacy. The calibration curve indicated a good fit of the model ( P>0.05). The decision curve analysis showed positive net benefits at all thresholds. Conclusions:Currently, EPIs have a high incidence of longitudinal EUGR. The prediction model is helpful for early identification and intervention for EPIs with higher risks of longitudinal EUGR. It is necessary to expand the sample size and conduct prospective studies to optimize and validate the prediction model in the future.

ObjectiveKaroshi, death from overwork, is a serious problem with unclear identification standards and mechanisms. This study aims to establish a karoshi rat model by integrating weight-bearing swimming and sleep deprivation. This model will enable us to investigate the adverse effects of acute physical and mental fatigue on cardiac functions and explore the response mechanisms to overwork using integrated omics approaches, specifically metabonomics and proteomics. MethodsThe experimental design involved healthy male sprague-dawley (SD) rats subjected to weight-bearing swimming and sleep deprivation for 7 d. The rats were monitored for changes in physiological function indexes, including electrocardiogram and respiration. Protein digestion, iTRAQ labeling, and quantitative data analyses were performed to determine differentially expressed proteins (DEPs). Additionally, GC-MS analysis was conducted to identify differential metabolites. The integration analysis of differential metabolites and proteins shared by the fatigue group and the overwork group was performed to construct a relevant metabolic pathway network and integrate the proteomics and metabolomics data. Statistical analysis was carried out using one-way ANOVA and Duncan’s multiple range t-tests. ResultsThe rats subjected to weight-bearing swimming and sleep deprivation showed various physical and behavioral changes associated with fatigue, including hair disorder, decreased muscle tension, reduced food intake, and weight loss. Analysis of cardiac functions revealed cardiac hypertrophy and heart failure in the fatigue and karoshi groups, as evidenced by changes in heart color, myocardial fiber structure, heart rate, respiratory rate, and cardiac ultrasound measurements. Metabolomics analysis using GC-MS identified several differential metabolites in response to overwork, including amino acids involved in various metabolic pathways. Proteomic analysis using iTRAQ technology identified DEPs in the fatigue and karoshi groups, with a subset of DEPs shared by both groups. The GO analysis revealed that the up-regulated DEPs were primarily associated with mitochondria and peroxisomes in the cellular component category. The Reactome analysis further highlighted the enrichment of DEPs in the transfer of ferriheme from methemoglobin to hemopexin pathway. Integration analysis of the DEPs and differential metabolites revealed the activation of autophagy, increased mitochondrial oxidative phosphorylation, enhanced branched-chain amino acid degradation, and altered peroxisomal β-oxidation. These findings suggested complex metabolic adaptations to meet the increased energy demands during overwork while also dealing with oxidative stress. Furthermore, the reprogramming of energy metabolism was observed, with upregulation of fatty acid β-oxidation enzymes and glycolysis-related enzymes in the fatigue group, indicating a shift towards glucose metabolism. In contrast, the karoshi group showed a decreased dependence on fatty acids as an energy source and increased utilization of glucose. The model proposed in this study highlights the interconnected metabolic changes involving mitochondria, peroxisomes, and lysosomes in response to overwork. The findings contribute to our understanding of the mechanisms involved in overwork-related pathologies and provide a basis for further research in the field of karoshi. ConclusionOverall, metabolic reprogramming might provide sufficient energy to the heart, alleviate oxidative stress and damage to cardiac cells in response to excessive exertion and fatigue. Our findings provide an insight into response mechanism to overwork death and lay a foundation for further research on overwork death.

Ankylosing spondylitis (AS) combined with lower cervical fracture is often categorized into unstable fracture, with a high incidence of neurological injury and a high rate of disability and morbidity. As factors such as shoulder occlusion may affect the accuracy of X-ray imaging diagnosis, it is often easily misdiagnosed at the primary diagnosis. Non-operative treatment has complications such as bone nonunion and the possibility of secondary neurological damage, while the timing, access and choice of surgical treatment are still controversial. Currently, there are no clinical practice guidelines for the treatment of AS combined with lower cervical fracture with or without dislocation. To this end, the Spinal Trauma Group of Orthopedics Branch of Chinese Medical Doctor Association organized experts to formulate Clinical guidelines for the treatment of ankylosing spondylitis combined with lower cervical fracture in adults ( version 2024) in accordance with the principles of evidence-based medicine, scientificity and practicality, in which 11 recommendations were put forward in terms of the diagnosis, imaging evaluation, typing and treatment, etc, to provide guidance for the diagnosis and treatment of AS combined with lower cervical fracture.

Objective:To study the expression of the Homeobox C6(HOXC6)gene in the homeobox family in PCa,its effect on the biological behavior of PCa cells and its action mechanism.Methods:Based on the studies of HOXC6 retrieved from the data-base of Gene Expression Profiling Interactive Analysis(GEPIA),we analyzed the expression of HOXC6 in PCa and the relationship of its expression level with the survival prognosis of the patients.We detected the expression of the HOXC6 protein in PCa tissues and cells by Western blot,stably interfered with the expression of the HOXC6 gene in human PCa DU145 and PC-3 cells and normal prosta-tic epithelial RWPE-1 cells using the siRNA plasmid,and determined the effects of HOXC6 on the proliferation,migration and inva-siveness of PCa cells by CCK8,plate cloning and scratch healing and Transwell invasion assays.Using the GEPIA database,we ana-lyzed the correlation of the Wnt tumor inhibitory factor-secreted frizzled-related protein 1(SFRP1)gene with HOXC6,and detected the expressions of HOXC6,SFRP1,Wnt and β-catenin in PC-3 cells after siRNA-HOXC6 transfection by Western blot.Results:The expression of HOXC6 was dramatically higher in the PCa than in the normal prostate tissue(P<0.01),and in the PCa cells than in the normal prostatic epithelial cells(P<0.01).Bioinformatics analysis indicated a lower survival rate of the PCa patients with a high than those with a low HOXC6 expression(P=0.011).The relative expression of the HOXC6 protein,absorbance value,number of clones formed and number of invaded cells were significantly lower in the siRNA group than in the negative controls(P<0.05).Ac-cording to the GEPIA database,highly expressed SFRP1 was associated with a good prognosis of PCa,and the protein expressions of Wnt and β-catenin were markedly increased while that of SFRP1 decreased in the PCa PC-3 cell line(P<0.05).The expressions of the Wnt and β-catenin proteins were decreased and that of SFRP1 increased significantly in the siRNA-HOXC6 transfection group com-pared with those in the siRNA negative control and PCa PC-3 groups(P<0.05).Conclusion:HOXC6 is highly expressed in PCa tissues and related to the proliferation,migration and invasiveness of PCa cells.HOXC6 promotes the growth of DU145 and PC-3 cells in PCa by inhibiting the SFRP1/Wnt/β-catenin signaling pathway,and may be a potential target for clinical treatment of PCa.

Objective:To analyze the related factors of treatment failure in children with acute lymphoblastic leukemia (ALL)in real-world.Methods:The clinical data of 1414 newly diagnosed children with ALL admitted to five hospital in Fujian province from April 2011 to December 2020 were retrospectively analyzed.Treatment failure was defined as relapse,non-relapse death,and secondary tumor.Results:Following-up for median time 49.7 (0.1-136. 9)months,there were 269 cases (19.0％)treatment failure,including 140 cases (52.0％)relapse,and 129 cases (48.0％)non-relapse death.Cox univariate and multivariate analysis showed that white WBC≥50 ×109/L at newly diagnosis,acute T-cell lymphoblastic leukemia (T-ALL),BCR-ABL1,KMT2A-rearrangement and poor early treatment response were independent risk factor for treatment failure (all HR>1.000,P<0.05).The 5-year OS of 140 relapsed ALL patients was only 23.8％,with a significantly worse prognosis for very early relapse (relapse time within 18 months of diagnosis).Among 129 patients died from non-relapse death,71 cases (26.4％)were died from treatment-related complications,56 cases (20.8％)died from treatment abandonment,and 2 cases (0.7％)died from disease progression.Among them,treatment-related death were significantly correlated with chemotherapy intensity,while treatment abandonment were mainly related to economic factors.Conclusion:The treatment failure of children with ALL in our province is still relatively high,with relapse being the main cause of treatment failure,while treatment related death and treatment abandonment caused by economic factors are the main causes of non-relapse related death.
