Objective:To analyze the short-term clinical efficacy and safety of arsenic trioxide (ATO) combined with a modified N7 induction regimen in the treatment of children with high-risk neuroblastoma (NB).Methods:This study was a prospective, single-arm, multicenter phase Ⅱ clinical study. Sixty-seven high-risk NB children from eight units of Sun Yat-sen Memorial Hospital of Sun Yat-sen University, Wuhan Children′s Hospital of Tongji Medical College of Huazhong University of Science and Technology, First Affiliated Hospital of Guangxi Medical University, Hainan General Hospital, Affiliated Hospital of Guangdong Medical University, Kunming Children′s Hospital, Tongji Hospital of Tongji Medical College of Huazhong University of Science and Technology, and Guangdong Provincial Agricultural Reclamation Center Hospital were enrolled from January 2019 to August 2023 and were treated with ATO combined with a modified N7 induction regimen. The efficacy and adverse effects at the end of induction chemotherapy were assessed and analyzed, and the differences in the clinical characteristics were further compared between the treatment-responsive and treatment-unresponsive groups by using the Fisher′s exact test.Results:Among 67 high-risk NB children, there were 40 males (60%) and 27 females (40%), with the age of disease onset of 3.5 (2.6, 4.8) years. Primary NB sites were mostly in retroperitoneum (including adrenal gland) (56/67, 84%) and the common metastases sites at initial diagnosis were distant lymph node in 25 cases (37%),bone in 48 cases (72%),bone marrow in 56 cases (84%) and intracalvarium in 3 cases (4%). MYCN gene amplification were detected in 28 cases (42%). At the end of induction, 33 cases (49%) achieved complete remission, 29 cases (43%) achieved partial remission, 1 case (1%) with stable disease, and 4 cases (6%) were assessed as progressive disease (PD). The objective remission rate was 93% (62/67) and the disease control rate was 94% (63/67). The percentage of central system metastases at the initial diagnosis was higher in the treatment-unresponsive group than in the treatment-responsive group (2/5 vs. 2% (1/62), P=0.013), whereas the difference in MYCN gene amplification was not statistically significant between two groups (3/5 vs.40% (25/62), P=0.786). Grade Ⅲ or higher adverse reactions during the induction chemotherapy period were myelosuppression occurred in 60 cases (90%), gastrointestinal symptoms occurred in 33 cases (49%), infections occurred in 20 cases (30%), hepatotoxicity occurred in 4 cases (6%), and cardiovascular toxicity occurred in 1 case (2%). There were no chemotherapy-related deaths. Conclusion:ATO combined with N7-modified induction regimen had a superiority in efficacy and safety, which deserved further promotion in clinical practice.

Colorectal cancer is one of the common malignant tumors of the digestive tract.With the popularization of screening methods and advancement of endoscopic technology,an increasing number of T1 stage colorectal cancers can be discovered.Accurately predicting lymph node metastasis risk is significantly important for guiding clinical treatment decisions,reducing complications and mortality.Current research on risk factors for lymph node metastasis in T1 stage colorectal cancer covers multiple aspects including clinical pathological features,molecular phenotypes and genetic characteristics.Some studies have built prediction models by integrating these factors,which show higher sensitivity,specificity and accuracy compared to current clinical guidelines.These models provide valuable experience for clinical practice.

Although carbon monoxide (CO)-based treatments have demonstrated the high cancer efficacy by promoting mitochondrial damage and core-region penetrating ability, the efficiency was often compromised by protective autophagy (mitophagy). Herein, cannabidiol (CBD) is integrated into biomimetic carbon monoxide nanocomplexes (HMPOC@M) to address this issue by inducing excessive autophagy. The biomimetic membrane not only prevents premature drugs leakage, but also prolongs blood circulation for tumor enrichment. After entering the acidic tumor microenvironment, carbon monoxide (CO) donors are stimulated by hydrogen oxide (H₂O₂) to disintegrate into CO and Mn²⁺. The comprehensive effect of CO/Mn²⁺ and CBD can induce ROS-mediated cell apoptosis. In addition, HMPOC@M-mediated excessive autophagy can promote cancer cell death by increasing autophagic flux via class III PI3K/BECN1 complex activation and blocking autolysosome degradation via LAMP1 downregulation. Furthermore, in vivo experiments showed that HMPOC@M+ laser strongly inhibited tumor growth and attenuated liver and lung metastases by downregulating VEGF and MMP9 proteins. This strategy may highlight the pro-death role of excessive autophagy in TNBC treatment, providing a novel yet versatile avenue to enhance the efficacy of CO treatments. Importantly, this work also indicated the applicability of CBD for triple-negative breast cancer (TNBC) therapy through excessive autophagy.

Chronic refractory wound (CRW) is one of the most challengeable issues in clinic due to complex pathogenesis, long course of disease and poor prognosis. Experts need to conduct systematic summary for the diagnosis and treatment of CRW due to complex pathogenesis and poor prognosis, and standard guidelines for the diagnosis and treatment of CRW should be created. The Guideline forthe diagnosis and treatment of chronic refractory wounds in orthopedic trauma patients ( version 2023) was created by the expert group organized by the Chinese Association of Orthopedic Surgeons, Chinese Orthopedic Association, Chinese Society of Traumatology, and Trauma Orthopedics and Multiple Traumatology Group of Emergency Resuscitation Committee of Chinese Medical Doctor Association after the clinical problems were chosen based on demand-driven principles and principles of evidence-based medicine. The guideline systematically elaborated CRW from aspects of the epidemiology, diagnosis, treatment, postoperative management, complication prevention and comorbidity management, and rehabilitation and health education, and 9 recommendations were finally proposed to provide a reliable clinical reference for the diagnosis and treatment of CRW.

Objective:To investigate the efficacy of two-way needle suture technique (TNST) in the minimally invasive repair of acute closed Achilles tendon rupture.Methods:From June 2019 to June 2021, 26 patients with acute closed Achilles tendon rupture were treated at Zhengzhou Orthopedic Hospital. They were 20 males and 6 females, with a mean age of 28 (23, 31) years. The rupture end was (4.2±1.3) cm away from the calcaneal insertion, and the interval from injury to operation 4.3 (2.0, 5.0) d. Preoperative MRI examinations revealed in all the patients closed Achilles tendon rupture which was to be repaired by TNST. The operation time, incision length, incidence of complications, ankle dorsiflexion and plantar flexion were recorded. The Arner-Lindholm scoring was used to evaluate the clinical efficacy.Results:The operation time was (20.0±5.0) min and the incision length (2.5±0.4) cm. Postoperatively, all incisions healed by the first stage, with no complications like incision infection, skin edge necrosis, deep vein thrombosis at lower limbs, injury to the sural nerve, or re-rupture of the Achilles tendon. All patients were followed up for (12.0±6.0) months. At the last follow-up, the patients walked normally, their incisions healed well, the continuity of the Achilles tendon was good by palpation, their heel lift was strong, and all their activities were restored to the levels before rupture of the Achilles tendon. The ankle dorsiflexion was 22.6°±3.7° and the plantar flexion 25.3°±3.7°, According to the Arner-Lindholm evaluation, the clinical efficacy was rated as excellent in 25 cases and as good in 1 case, giving an excellent and good rate of 100% (26/26).Conclusion:In the minimally invasive repair of acute closed Achilles tendon rupture, TNST shows the advantages of limited surgical invasion, a low incidence of postoperative complications, and reliable curative effects.

Objective:To report the first case of sever fever with thrombocytopenia syndrome caused by severe fever with thrombocytopenia syndrome virus (SFTSV) in Puyang city, and to study the epidemiological and molecular characteristics of S, M, L fragments of the SFTSV isolate.Methods:The epidemiological characteristics of this case was analyzed with epidemiological methods. SFTSV was isolated from the patient′s serum sample. Nucleic acid of SFTSV was extracted and detected by fluorescent RT-PCR. A multiplex PCR method was constructed to amplify the nucleic acid sequence of the virus. whole-genome sequencing was performed on the next-generation sequencing platform. MEGA11 and DNAStar was used for homology analysis and a phylogenetic tree was constructed.Results:Epidemiological investigation showed that the patient and his close contacts had no history of travel or tick bite within 14 d, but had a history of fieldwork. The patient′s serum sample was positive for SFTSV nucleic acid. Genetic analysis showed that the S, M, L gene fragments of the first SFTSV isolate in Puyang belonged to genotype E. This isolate shared 94.8%-99.6%, 94.0%-99.8% and 95.7%-99.7% nucleotide sequence homology with the representative strains acquired from GeneBank in S, M, L gene fragments, respectively.Conclusions:This case was the first case of SFTSV-caused severe fever with thrombocytopenia syndrome in Puyang. The SFTSV isolate shared a close homology with domestic isolates, but its genotype was significantly different from the SFTSV strains isolated in Henan in recent years, indicating that it might an imported case from other places in Henan Province or Hubei Province. Disease monitoring and professional training for medical personnel should be strengthened and more attention should be paid to the evolution and mutation of SFTSV.

Objective: This study is designed to compare the changes of intestinal microflora and cytokine levels in patients with schizophrenia in different periods, analyze the correlation between intestinal microflora and disease symptoms, and explore the influence of intestinal microflora changes on the symptoms of patients with schizophrenia. Methods: 40 schizophrenic patients in different periods were included in the study, with their demographic data of age, body mass index(BMI), sex and course of disease collected. For each subject, serum was first collected for the levels of cytokines to be determined by an Meso Scale Discovery. The severity of schizophrenia was then assessed using negative and positive symptom scales. Finally macrofactor sequencing of intestinal flora was performed using MetaGeneMark. Results: Serum levels of interleukin-6(IL-6), interleukin-10(IL-10), interleukin-17(IL-17), interleukin-23(IL-23), and tumor necrosis factor-α(TNF-α) in the acute stage were higher than those in remission stage, and the results were statistically significant(P<0.05). Negative and positive symptom Scale(PANSS) positive factor scores were negatively correlated with TNF-α and IL-17(R=-0.312,P<0.05;R=-0.399,P<0.05); IL-23 was positively correlated with the negative factor score of the scale(R=-0.344,P<0.05). IL-6 was positively correlated with scale cognitive factor score(R=-0.339,P<0.05). IL-23 was positively correlated with the total score of the scale(R=-0.370,P<0.05). The microbial diversity detected in stool samples of patients with acute schizophrenia was lower than that of patients with remission, and certain difference was detected in the intestinal flora species composition between patients in the acute stage and in the remission stage. Conclusion The level of serum cytokines in the acute stage of schizophrenia is higher than that in the remission stage, and some cytokines levels are correlated with clinical symptoms.

Objective:To analyse the pathogenic bacteria distribution and clinical characteristics of late-onset sepsis (LOS) among premature infants with gestational age less than 34 weeks in Henan Province.Methods:The clinical data of 6 590 premature infants admitted to 17 medical institutions in Henan Province from January 2019 to December 2020 were retrospectively analyzed. The gestational age of infants was less than 34 weeks and was admitted to the neonatal ward within 7 days after birth. SPSS 19.0 statistical software was used for data analysis.Results:Among 6 590 premature infants LOS developed in 751 cases (11.40%), of whom the diagnosis was confirmed in 276 cases (36.75%) and 475 cases (63.25%) were diagnosed clinically. The fatality rate related to LOS was 13.58%. There were significant differences in the incidence of LOS and infection-related mortality among infants with different gestational ages and body weights ( χ2=388.894 and 13.572, χ2=472.282 and 9.257, P<0.05 or <0.01). Among 276 children with confirmed LOS, 286 strains of pathogenic bacteria were isolated. Gram-negative bacteria were most prevalent (178 strains), accounting for 62.24% of all infections, followed by fungi (58 strains, 20.28%). Klebsiella pneumoniae was most frequently detected Gram-negative bacteria (117 strains, 40.91%), among which 32.48% (38/117) was carbapenem-resistant Klebsiella pneumoniae. The proportion of diagnosed sepsis, the proportion of catheterization, and the infection-related mortality of infants with LOS in tertiary hospitals were all higher than those in secondary hospitals ( χ2=6.212, 5.313 and 4.435, all P<0.05). The proportion of exclusive breastfeeding in secondary hospitals was lower than that in tertiary hospitals ( χ2=19.216, P<0.05). The time of antibacterial drug use before infection in specialized hospitals was longer than that in general hospitals ( χ2=3.276, P<0.05). Conclusion:The incidence of LOS among preterm infants in Henan Province is high, which was mainly caused by Gram-negative bacteria. The clinical characteristics of LOS caused by different pathogens and in different health institutions are different, the prevention and control strategy should be developed accordingly to reduce the incidence LOS of preterm premature infants.
