Acupuncture Provides Short-Term Functional Improvements and Pain Relief for Patients After Knee Replacement Surgery: A Systematic Review and Meta-analysis.

The impact of acupuncture on knee function and pain intensity following knee replacement remains controversial. Therefore, we categorized the postsurgery recovery period into 3 phases: short-term (≤2 weeks), intermediate-term (2 weeks-3 months), and long-term (>3 months), and then assessed the effectiveness of acupuncture in improving function and alleviating pain at different stages following knee replacement. This meta-analysis included randomized controlled trials that compared acupuncture intervention with either no treatment or a sham group after knee replacement. Six databases were searched from inception to December 31, 2023, including PubMed, Embase, Cochrane Central Register of Controlled Trials, Web of Science, and 2 Chinese databases (Chinese National Knowledge Infrastructure and WanFang Data). A total of 23 studies comprising 1,464 participants were included. Significant improvement of active range of motion was observed on day 7 and week 2 after operation. Lower pain intensity at rest was noted in patients receiving acupuncture in short-term periods after operation (12 hours, day 1, day 2, day 5, and week 2). A reduction in pain intensity during movement with acupuncture was observed on postoperative day 1 and day 7. Auricular acupuncture did not show not significant effectiveness in improving range of motion and pain intensity. For conventional acupuncture, the combination of distal and local point selection was found to be the most effective. Early application of acupuncture, in conjunction with physical therapy, starting before postoperative day 1 or day 2, was recommended. Further high-quality researches are warranted to validate the findings in this meta-analysis. PERSPECTIVE: This article demonstrates that acupuncture has short-term effects (≤2 weeks) on improving active range of motion and reducing pain during rest and during movement following knee replacement surgery. The findings support the early application of acupuncture in hospital settings after knee replacement. REGISTRATION ID: The study was registered on PROSPERO (CRD42024503479).

Kombo knife combined with sorafenib in liver cancer treatment: Efficacy and safety under immune function influence.

BACKGROUND: In the quest to manage hepatocellular carcinoma (HCC), the focus has shifted to a more holistic approach encompassing both data analytics and innovative treatments. Analyzing rich data resources, such as the cancer genome atlas (TCGA), and examining progressive therapies can potentially reshape the trajectory of HCC treatment. AIM: To elucidate the immunological genes and the underlying mechanism of the combined Kombo knife and sorafenib regimen for HCC by analyzing data from TCGA and machine learning data. METHODS: Immune attributes were evaluated via TCGA's postablation HCC RNA sequencing data. Using weighted gene coexpression network analysis and machine learning, we identified genes with high prognostic value. The therapeutic landscape and safety metrics of the integrated treatment were critically evaluated across cellular and animal models. RESULTS: Immune genes-specifically, peptidylprolyl isomerase A and solute carrier family 29 member 3-emerged as significant prognostic markers. Enhanced therapeutic outcomes, such as prolonged progression-free survival and an elevated overall response rate, characterize the combined approach, with peripheral blood mononuclear cells displaying potent effects on HCC dynamics. CONCLUSION: The combination of Kombo knife with sorafenib is an innovative HCC treatment modality anchored in immune-centric strategies.

A controlled trial of elastic fixation and absolute fixation for treatment of ankle fractures with lower tibiofibular instability / 中国组织工程研究

BACKGROUND:Although traditional screw fixation has been successful in treating ankle fractures,rigid fixation solutions tend to restrict ankle movement and delay fracture healing,whereas elastic fixation is more compatible with human mechanics and has unique advantages in patients with ankle fractures. OBJECTIVE:To compare the clinical effectiveness of elastic fixation and absolute fixation in repairing ankle fractures in the elderly with lower tibiofibular instability. METHODS:The clinical data of 108 elderly ankle fractures with lower tibiofibular instability in Hengshui People's Hospital from August 2019 to August 2021 were retrospectively collected.They were divided into screw group and elastic fixation group(n=54 per group)according to the surgical protocol,and traditional screw internal fixation and elastic internal fixation were performed respectively.The perioperative indicators,surgical results,economic benefits,and American orthopedic foot and ankle society scores were collected and compared between the two groups.Serum tumor necrosis factor-α,interleukin-8 levels,ankle cavity width,depth,and lower tibiofibular space were compared before and after surgery. RESULTS AND CONCLUSION:(1)The full weight-bearing time was shorter in the elastic fixation group than that in the screw group;the operating angle was greater in the elastic fixation group than that in the screw group,and the complication rate was lower in the elastic fixation group than that in the screw group(P<0.05).(2)Serum tumor necrosis factor-α and interleukin-8 levels in the elastic fixation group were lower than those in the screw group 3 days after surgery(P<0.05).(3)American orthopedic foot and ankle society scores in the two groups were higher than those before surgery at 6 and 12 months after surgery,and the depth and width of the inferior tibiofibular space and ankle cavity were lower than those before surgery(P<0.05);but no significant difference was detected between the two groups(P>0.05).(4)There was no significant difference in the excellent and good rate between the two groups at 12 months after surgery(P>0.05).(5)There was no significant difference in the comparison of direct non-medical costs,direct medical costs,and total costs between the two groups(P>0.05).(6)It is indicated that elastic fixation for the repair of ankle fractures with lower tibiofibular instability in the elderly can obtain effective outcomes,which can shorten the time of complete weight-bearing,diminish complications,and alleviate inflammatory stress.

Objective:To summarize the clinical characteristics of multisystem inflammatory syndrome in children（MIS-C）related to SARS-CoV-2 and analyze the risk factors for hypotension.Methods:The clinical data of children with MIS-C who visited Beijing Children's Hospital from January 2023 to March 2023 were retrospectively collected,and the clinical characteristics and risk factors for hypotension were analyzed.Results:Thirty-six patients were included,the median age was 3.1 (2.3,5.8) years; 61.1% were boys.All cases had a history of SARS-CoV-2 infection between 1 and 9 weeks before onset.Clinical symptoms included fever (100.0%); rash (94.4%); bilateral conjunctival congestion (88.8%); lips/oral cavity changes (100.0%); swollen hands and foot (61.1%); cervical lymphadenopathy (88.8%); acute gastrointestinal symptoms (61.1%) of diarrhea,abdominal pain and vomiting; neurologic manifestations (33.3%) of lethargy,headache,and convulsions; respiratory symptoms(41.6%) of cough,sore throat and shortness of breath.Nineteen (52.8%) cases developed hypotension and needed vasoactive drugs support to maintain blood pressure.Mechanical ventilation was required in four(11.1%) cases,and one patient was intubated and treated with continuous renal replacement therapy.The level of ferritin in hypotension group was significantly higher than those in normal blood pressure group( P＜0.05),while the levels of platelet count,serum sodium and potassium in hypotension group were significantly lower than those in normal blood pressure group( P＜0.05).Logistic regression multivariable analysis found the elevated serum ferritin ( OR=20.000,95% CI:2.750-145.481, P=0.003) was an independent risk factor for hypotension. Conclusions:MIS-C may be observed following SARS-CoV-2 infection.Various symptoms and signs,including fever,multiple organ dysfunction,and hypotension,may occur in children with MIS-C.Elevated ferritin is a risk factor for hypotension.

Targeting ferroptosis for treatment of Alzheimer' s disease / 中国药理学通报

Alzheimer' s disease (AD) is a progressive neurodegenerative disorder histologically characterized by the presence of senile plaques and neurofibrillary tangles (NFTs) found in and around pyramidal neurons in cortical tissue. Mounting evidence suggests regional increased iron load and dyshomeostasis have been associated with oxidative stress, oxidation of proteins and lipids, and cell death, and appears to be a risk factor for more rapid cognitive decline, thereby involved in multiple aspects of the pathophysiology of AD. Ferroptosis is a newly identified iron-dependent lipid peroxidation-driven cell death and emerging evidences have demonstrated the involvement of ferroptosis in the pathological process of AD. Notably, some novel compounds targeting ferroptosis can relieve AD-related pathological symptoms in AD cells and animal model and exhibit potential clinical benefits in AD patients. This review systematically summarizes the growing molecular and clinical evidence implicating ferroptosis in the pathogenesis of AD, and then reviews the application of ferroptosis inhibitors in mouse/cell models to provide valuable information for future treatment and prevention of AD.

A preliminary research on transcultural capacity in global public health: from the view of public health professionals.

BACKGROUND: Transcultural capacity is a key component of consolidated global public health assistance cooperation (GPHAC). The aim of this study is to investigate the transcultural capacity perceptions of public health professionals from China's disease control and prevention system after relative training in order to provide a reference for enhancing transcultural capacity during the practice of GPHAC. METHODS: A cross sectional qualitative survey in which self-administrated questionnaire with 5 open ended questions was used. The questionnaire was disseminated on the completion of an online training for China's senior public health professions on transcultural capacity in GPHAC. Descriptive statistics, word frequency analysis and content analysis were used to analyze the questionnaire data. RESULTS: Totally, 45 participants took part in this training, 25 of them voluntarily participated in this survey. The participants demonstrated the need for transcultural competence in public health services and suggested improvement in the course content arising from their wealth of knowledge and practical experience in the field. 96% of the participants considered that the training course was "very necessary" and "meaningful". The most interested topics were "Overview of transcultural adaptation and GPHAC", "Transcultural adaptation and response" and "African culture and health". The contents about "Country-specific analysis on cultural factors in public health", "rapid transcultural adaptation" and "more specific practical experiences in diverse cultural backgrounds" were suggested to be added in future training. The participants considered that transcultural capacity ensured the smooth progress of GPHAC and they both could complement each other, transcultural adaptation was the premise of gaining trust and reaching cooperation, it can be conducive to the health assistance professionals to integrate into local cultural life, facilitating their foreign assistance work to be effective and efficient, and impart experiences well. The participants hoped to put the concept into action. CONCLUSION: The importance of transcultural competence in GPHAC is becoming a consensus of public health professionals. Enhanced transcultural competence reflected in the attitude of public health as well as other health workers would promote GPHAC and would foster efficient emergency health response management among many countries.

Role of lipopolysaccharide in the development and progression of liver cancer / 临床肝胆病杂志

Liver cancer is an important public health issue worldwide. With the improvements in high-throughput sequencing and gene editing techniques in recent years, studies have further revealed the biological mechanism of intestinal microflora in the development, progression, and metastasis of liver cancer via the gut-liver axis, and in particular, it has been found that lipopolysaccharide, a component of the outer membrane of gram-negative bacteria, can cause downstream immune cascade reactions. This article reviews the possible mechanism of action of intestinal microflora lipopolysaccharide in the development and progression of liver cancer from the aspects of the association between intestinal environmental changes and liver cancer, immunoregulation by lipopolysaccharide, and preclinical treatment.

The paper presents professor WU Han-qing's experience in treatment of lumbar disc herniation (LDH) with "sinew-bone three needling technique" of Chinese medicine. Based on the theory of meridian sinew, the points are located by "three-pass method" in terms of the distribution of meridian sinew and syndrome/pattern differentiation. The cord-like muscles and adhesion are relieved by relaxing technique to work directly on the affected sites and alleviate the local compression to the nerve root. The needle technique is operated flexibly according to the affected regions involved, due to which, the needling sensation is increased while the safety ensured. As a result, the meridian qi is enhanced, the mind and qi circulation is regulated; and the clinical effect is improved.

Therapeutic potential of targeting SIRT1 for the treatment of Alzheimer's disease / 生理学报

Silent information regulator 1 (SIRT1) is one of the seven mammalian proteins of the sirtuin family of NAD+-dependent deacetylases. SIRT1 plays a pivotal role in neuroprotection and ongoing research has uncovered a mechanism by which SIRT1 may exert a neuroprotective effect on Alzheimer's disease (AD). Growing evidence demonstrates that SIRT1 regulates many pathological processes including amyloid-β precursor protein (APP) processing, neuroinflammation, neurodegeneration, and mitochondrial dysfunction. SIRT1 has recently received enormous attention, and pharmacological or transgenic approaches to activate the sirtuin pathway have shown promising results in the experimental models of AD. In the present review, we delineate the role of SIRT1 in AD from a disease-centered perspective and provides an up-to-date overview of the SIRT1 modulators and their potential as effective therapeutics in AD.

Discovery of novel phosphodiesterase-1 inhibitors for curing vascular dementia: Suppression of neuroinflammation by blocking NF-κB transcription regulation and activating cAMP/CREB axis

Vascular dementia (VaD) is the second commonest type of dementia which lacks of efficient treatments currently. Neuroinflammation as a prominent pathological feature of VaD, is highly involved in the development of VaD. In order to verify the therapeutic potential of PDE1 inhibitors against VaD, the anti-neuroinflammation, memory and cognitive improvement were evaluated in vitro and in vivo by a potent and selective PDE1 inhibitor 4a. Also, the mechanism of 4a in ameliorating neuroinflammation and VaD was systematically explored. Furthermore, to optimize the drug-like properties of 4a, especially for metabolic stability, 15 derivatives were designed and synthesized. As a result, candidate 5f, with a potent IC50 value of 4.5 nmol/L against PDE1C, high selectivity over PDEs, and remarkable metabolic stability, efficiently ameliorated neuron degeneration, cognition and memory impairment in VaD mice model by suppressing NF-κB transcription regulation and activating cAMP/CREB axis. These results further identified PDE1 inhibition could serve as a new therapeutic strategy for treatment of VaD.

Salvianolic acid A contributes to cartilage endplate cell restoration by regulating miR-940 and miR-576-5p / 中国骨伤

OBJECTIVE@#To investigate whether Salvianolic acid A (SAA) can restore cartilage endplate cell degeneration of intervertebral discs and to identify the mechanism via regulation of micro-RNA.@*METHODS@#Cartilage endplate cells were isolated from lumbar intervertebral disc surgical samples and were treated with serum containing a series of concentrations of SAA (2, 5, and 10 ?M) for 24, 48, and 72 h to identify a proper dose and treatment time of SAA. The effect SAA on interlenkin-1β (IL-1β)-induced extracellular matrix degradation of cartilage endplate cells were analyzed by Alcian blue staining and assessment of the expression levels of ADAMTS-5, MMP3 and Col2a1. Further, the potential target miRNAs were preliminarily screened by micro-RNA sequencing combining qRT-PCR and Western blot, and then, the miRNAs mimics and inhibitors were used to verify the regulatory effect of SAA on potential target miRNAs.@*RESULTS@#The 10 μM SAA treatment for 48 h significantly enhanced the viability of cartilage endplate cells, and increased Col2a1 expression and glycosaminoglycan accumulation that were repressed by IL-1β, and reduced the effect of IL-1β on ADAMTS-5, and MMP3. Screening analysis based on micro-RNA sequencing and Venny analysis identified the downstream micro-RNAs, including miR-940 and miR-576-5p. Then, the miR-940-mimic or miR-576-5p-mimic were transfected into CEPCs. Compared with the SAA group, the expression of ADAMTS-5 and MMP3 increased significantly and the expression of COL2A1 obviously decreased after overexpression of miR-940 or miR-576-5p in CEPCs.@*CONCLUSION@#Salvianolic acid A attenuated the IL-1β-induced extracellular matrix degradation of cartilage endplate cells by targeting regulate the miR-940 and the miR-576-5p.

Whole-course management strategies for gastroesophageal reflux disease: an evidence mapping study based on clinical practice guidelines / 中华胃肠外科杂志

Gastroesophageal reflux disease (GERD) is one of the most common digestive diseases with high incidence, complicated clinical symptoms, difficulties in standard treatment, and heavy medical burden. At present, some GERD-relevant clinical practice guidelines (CPGs) have been issued by different countries and academic organizations, but some recommendations were inconsistent, which has caused some problems for the current clinical whole-course management of GERD. To summarize the relevant evidence among the CPGs on GERD and formulate the whole- course management strategies, we included GERD-relevant CPGs published or updated after 2010 by searching websites of guidelines, relevant professional societies, and electronic databases. We extracted the recommendations and summarized the evidence from the aspects of symptoms, epidemiology, diagnosis and treatment, which was presented in the form of evidence mapping. We included 24 CPGs, including three in Chinese and 21 in English. The clinical practice management strategies of GERD were formulated based on the evidence from the aspects of clinical symptoms, diagnostic methods, medical treatment, anti-reflux surgery and endoscopic treatment, psychological treatment, and traditional Chinese medicine treatment.

Phenotype-genotype analysis of the autosomal recessive hereditary hearing loss caused by OTOA variations / 中华耳鼻咽喉头颈外科杂志

Objective: To analyze the phenotypic-genotypic characteristics of hereditary deafness caused by OTOA gene variations. Methods: Family histories, clinical phenotypes and gene variations of six pedigrees were analyzed, which were diagnosed with hearing loss caused by OTOA gene variations at the PLA General Hospital from September 2015 to January 2022. The sequence variations were verified by Sanger sequencing and the copy number variations were validated by multiplex ligation-dependent probe amplification (MLPA) in the family members. Results: The hearing loss phenotype caused by OTOA variations ranged from mild to moderate in the low frequencies, and from moderate to severe in the high frequencies in the probands, which came from six sporadic pedigrees, among which a proband was diagnosed as congenital deafness and five were diagnosed as postlingual deafness. One proband carried homozygous variations and five probands carried compound heterozygous variations in OTOA gene. Nine pathogenic variations (six copy number variations, two deletion variations and one missense variation) and two variations with uncertain significance in OTOA were identified in total, including six copy number variations and five single nucleotide variants, and three of the five single nucleotide variants were firstly reported [c.1265G>T(p.Gly422Val),c.1534delG(p.Ala513Leufs*11) and c.3292C>T(p.Gln1098fs*)]. Conclusions: OTOA gene variations can lead to autosomal recessive nonsyndromic hearing loss. In this study, the hearing loss caused by OTOA defects mostly presents as bilateral, symmetrical, and postlingual, and that of a few presents as congenital. The pathogenic variations of OTOA gene are mainly copy number variations followed by deletion variations and missense variations.

Clinical management and prognosis for descending necrotizing mediastinitis / 中华耳鼻咽喉头颈外科杂志

Objective: To investigate the clinical characteristics, treatment experiences and prognostic factors for descending necrotizing mediastinitis (DNM). Methods: A retrospective analysis was performed on the data of 22 patients with DNM diagnosed and treated in Henan Provincial People's Hospital from January 2016 to August 2022, including 16 males and 6 females, aged 29-79 years. After admission, all patients underwent CT scanning of the maxillofacial, cervical, and thoracic regions to confirm their diagnoses. Emergency incision and drainage were performed. The neck incision was treated with continuous vacuum sealing drainage. According to the prognoses, the patients were divided into cure group and death group, and the prognostic factors were analyzed. SPSS 25.0 software was used to analyze the clinical data. Rusults: The main complaints were dysphagia (45.5%, 10/22) and dyspnea (50.0%, 11/22). Odontogenic infection accounted for 45.5% (10/22) and oropharyngeal infection accounted for 54.5% (12/22). There were 16 cases in the cured group and 6 cases in the death group, with a total mortality rate of 27.3%. The mortality rates of DNM typeⅠand typeⅡwere respectively 16.7% and 40%. Compared with the cured group, the death group had higher incidences for diabetes, coronary heart disease and septic shock (all P<0.05). There were statistically significant differences between the cure group and the death group in procalcitonin level (50.43 (137.64) ng/ml vs 2.92 (6.33) ng/ml, M(IQR), Z=3.023, P<0.05) and acute physiology and chronic health evaluation Ⅱ(APACHEⅡ) score (16.10±2.40 vs 6.75±3.19, t=6.524, P<0.05). Conclution: DNM is rare, with high mortality, high incidence of septic shock, and the increased procalcitonin level and APACHE Ⅱ score combined diabetes and coronary heart disease are the poor prognostic factors for DNM. Early incision and drainage combined with continuous vacuum sealing drainage technique is a better way to treat DNM.

Conclusion:LPG can be used to the treatment of proximal gastric cancer and adenocarcinoma of esophagogastric junction, with a good safety and short-term efficacy.

Clinical value of esophageal-jejunal Orvil TM anastomosis and Overlap anastomosis in laparos-copic radical total gastrectomy of adenocarcinoma of esophagogastric junction / 中华消化外科杂志

Objective:To investigate the clinical value of esophageal-jejunal OrVil TM anas-tomosis and Overlap anastomosis in laparoscopic radical total gastrectomy of adenocarcinoma of esophagogastric junction (AEG). Methods:The retrospective cohort study was conducted. The clinicopathological data of 112 patients with AEG who were admitted to the First Hospital of Jilin University from July 2017 to August 2022 were collected. There were 87 males and 25 females, aged (64±8)years. All 112 patients underwent laparoscopic total gastrectomy and D 2 lymphadenectomy, in which 61 cases with esophageal-jejunal OrVil TM anastomosis were divided into the OrVil TM group, 51 cases with esophageal-jejunal Overlap anastomosis were divided into the Overlap group. Observa-tion indicators: (1) surgical situations; (2) postoperative complications; (3) influencing factors for patients undergoing esophageal-jejunal OrVil TM anastomosis. Measurement data with normal distri-bution were represented as Mean± SD, and comparison between groups was conducted using the independent sample t test. Measurement data with skewed distribution were represented as M( Q1, Q3), and comparison between groups was conducted using the non-parameter test. Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test or Fisher exact probability. Logistic regression model was used for multivariate analysis. Results:(1) Surgical situations. The esophageal invasion length and tumor diameter was 1.0(0.7,2.0)cm and (6.3±2.7)cm in patients of the OrVil TM group, versus 0.2(0.1,0.5)cm and (4.7±2.2)cm, respectively, in patients of the Overlap group, showing significant differences in the above indicators between the two groups ( Z=?6.14, t=3.26, P<0.05). (2) Postoperative complications. Cases with complications ≥Ⅲa grade of Clavien-Dindo classification, cases with respiratory system complications, cases with hydrothorax were 13, 17, 13 in the OrVil TM group, versus 4, 5, 4 in the Overlap group, showing significant differences in the above indicators between the two groups ( χ2=3.91, 5.74, 3.91, P<0.05). Cases underwent readmission within postoperative 30 days were 3 and 1 in the OrVil TM group and the Overlap group, respectively, and all patients recovered after symptomatic treatment. There were 2 cases died after operation in the OrVil TM group and none of patients died after operation in the Overlap group. (3) Influencing factors for patients undergoing esophageal-jejunal OrVil TM anastomosis. Results of multivariate analysis showed that esophageal invasion length was an independent factor influencing for patients undergoing esophageal-jejunal OrVil TM anastomosis ( odds ratio=8.25, 95% confidence interval as 3.41?19.96, P<0.05). Conclusions:Compared with esophageal-jejunal Overlap anastomosis, choosing the esophageal-jejunal Orvil TM anastomosis during laparoscopic radical total gastrectomy can take benefit to the proximal margin of patients with AEG. However, the ratios of complications ≥ Ⅲa grade of Clavien-Dindo classification, respiratory system complications and hydrothorax associated to OrVil TM anastomosis are relatively increased. Esophageal invasion length is an independent influencing factor for patients undergoing esophageal-jejunal OrVil TM anastomosis.

Objective:To analyze the quality of surgical specimens of rectal cancer in the Chinese transanal total mesorectal excision (taTME) registry collaborative (CTRC) database.Methods:The retrospective and descriptive study was conducted. Based on the concept of real-world research, the clinicopathological data of 1 761 patients with rectal cancer in the CTRC database who underwent taTME in 40 medical centers, including the Beijing Friendship Hospital of Capital Medical University et al, from November 15, 2017 to December 31, 2022 were collected. There were 1 212 males and 549 females, aged 62(range, 53-68)years. Observation indicators: (1) preoperative examinations; (2) neoadjuvant therapy; (3) postoperative examinations. Measurement data with skewed distri-bution were represented as M(range). Count data were described as absolute numbers. Results:(1) Preoperative examinations. Of the 1 761 patients, 1 324 patients underwent preoperative pelvic magnetic resonance imaging examination, and the results showed that 4 cases as clinical T0 stage, 30 cases as clinical T1 stage, 250 cases as clinical T2 stage, 828 cases as clinical T3 stage, 141 cases as clinical T4 stage, 11 cases as clinical Tx stage, 60 cases missing clinical T staging data, 490 cases as clinical N0 stage, 373 cases as clinical N1 stage, 311 cases as clinical N2 stage, 86 cases as clinical Nx stage, 64 cases missing clinical N staging data, 156 cases with mesorectal fascia invasion, 223 cases with extraintestinal blood vessels invasion. The distance from lower margin of tumor to anal margin of 1 324 patients was 50(range, 40-60)mm. (2) Neoadjuvant therapy. Of the 1 761 patients, 873 patients underwent neoadjuvant therapy, including 17 cases receiving radiotherapy alone, 155 cases receiving chemotherapy alone, 43 cases receiving short-course simultaneous chemoradiotherapy, 26 cases receiving short-course simultaneous chemoradiotherapy and delayed surgery, 1 case receiving contact radiotherapy, 277 cases receiving long-course simultaneous chemoradiotherapy, 9 cases receiving other treatments, and 345 cases missing neoadjuvant therapy data. (3) Postoperative examinations. Of the 1 761 patients, 1 584 cases achieved R 0 resection, 23 cases achieved R 1 resection, 1 case achieved R 2 resection, and there were 153 cases missing surgical margin data. The tumor diameter, number of lymph nodes harvest and positive rate of intravascular tumor thrombus were 30(range, 20-45)cm, 13(range, 10-17) and 20.794%(330/1 587) in 1 761 patients. There were 1 647 patients with circumferential margin records, which showed positive in 51 cases, and the minimum distance from deep part of tumor to circumferential margin was 5(rang, 3-13)mm in 1 647 patients. There were 547 cases with distal margin records, which showed positive in 4 cases, and the distance from lower margin of tumor to distal margin was 20(10-25)mm in 547 cases. There were 1 698 patients with specimen integrity records, which showed intact specimen in 1 436 cases, fair specimen in 233 cases, poor specimen in 8 cases, unevaluated specimen in 21 cases, and there were 20 cases with rectal tube perforation. Of the 1 761 patients, cases as pathological T0 stage, Tis stage, T1 stage, T2 stage, T3 stage, T4 stage was 103, 23, 145, 515, 712, 179, respectively, and there were 4 cases of pathology that could not be evaluated and 80 cases missing pathological T staging data. Of the 1 761 patients, cases as pathological N0 stage, N1a stage, N1b stage, N1c stage, N2a stage, N2b stage was 1 117, 189, 133, 66, 109, 68, respectively, and there were 79 cases missing pathological N staging data. Of the 1 761 patients, there were 79 cases with distant metastasis, 1 591 cases without distant metastasis, and 91 cases without data of tumor metastasis. Of the 873 patients undergoing neoadjuvant therapy, there were 405 patients with tumor regression grade records including 105 cases as grade 1, 142 cases as grade 2, 91 cases as grade 3, 43 cases as grade 4, 24 cases as grade 5. Conclusions:In China, the quality of surgical specimens of taTME for rectal cancer is good with low positive rate of resection margin. It is recommended that using a formatted postoperative pathological report for good quality control of pathological report of surgical specimen.

Diagnostic and therapeutic strategies for severe influenza in children / 中华实用儿科临床杂志

The infection of influenza virus affects multiple organs and systems like the respiratory system in children, leading to severe influenza.High-risk children are particularly prone to severe influenza and even death.Influenza viruses can cause damage to the body through direct invasion and secondary immune responses.Pneumonia and influenza-associated encephalopathy are the most common severe intrapulmonary and extrapulmonary complications of influenza.Identifying high-risk groups, early management of antiviral treatment, and timely treatment of intrapulmonary and extrapulmonary complications of influenza contribute to improve the prognosis.Influenza vaccines are the most effective way of protection.
