Factors related to sarcopenia in hospitalized elderly patients / 中华老年医学杂志

Objective:To investigate the prevalence of sarcopenia and associated factors in hospitalized elderly patients.Methods:This was a cross-sectional study.A total of 578 patients admitted to the Geriatrics Department of our hospital were consecutively recruited according to the admission criteria.Patients were divided into the sarcopenia group(n=202, 34.95%)and non-sarcopenia group(n=376, 65.05%)based on the diagnostic criteria(2014)of the Asian Working Group for Sarcopenia.Their clinical data and laboratory parameters were collected.All patients underwent comprehensive geriatric assessment.Results:(1)The detection rate of sarcopenia in these hospitalized patients was 34.95%.(2)Age, free thyroxine(FT4), and the prevalences of diabetes and osteoporosis and the incidence of falls in the past year were higher while body mass index(BMI), calf circumference, hemoglobin(Hb), albumin(ALB), triglycerides(TG), low-density cholesterol(LDL), glycosylated hemoglobin(HbA1c)and free triiodothyronine(FT3)were lower in sarcopenia patients than in non-sarcopenia patients, with statistical significance.Scores on the mini-mental state examination(MMSE)and activities of daily living(ADL)were lower in sarcopenia patients than in non-sarcopenia patients while scores on nutritional risk screening 2002(NRS2002)and the FRAIL scale were higher, all with statistical significance.(3)Binary logistic regression analysis revealed that osteoporosis and FRAIL score were risk factors for sarcopenia( OR=9.083 and 2.505, P<0.001)and BMI, calf circumference and ADL score were protective factors for sarcopenia( OR=0.735, 0.774 and 0.967, P<0.05). (4)ROC analysis showed that the areas under the curve for FRAIL score, BMI, calf circumference and ADL score were 0.832, 0.805, 0.841 and 0.812, respectively, with threshold values at 2.5 points, 23.52 kg/m 2, 32.5 cm and 92.5 points.(5)The chi-square test for sarcopenia screening using various related factors found osteoporosis, calf circumference <32.5 cm and ADL <90 points had higher sensitivity(0.787, 0.807, 0.817)while FRAIL ≥ 3 points and BMI <23.5 had slightly lower sensitivity(0.683, 0.708), with each related factor having a high negative detection rate(0.833-0.888). Conclusions:The prevalence of sarcopenia in hospitalized elderly is more than 1/3.Osteoporosis and FRAIL score are risk factors for sarcopenia.BMI, calf circumference and ADL score are protective factors for sarcopenia.All relevant factors have practical clinical value and can be used for preliminary screening of sarcopenia.

Chinese expert consensus on diagnosis, treatment and prevention of venous thrombus embolism associated with chest trauma (2022 version) / 中华创伤杂志

Chest trauma is one of the most common injuries. Venous thromboembolism (VTE) as a common complication of chest trauma seriously affects the quality of patients′ life and even leads to death. Although there are some consensus and guidelines on the prevention and treatment of VTE at home and abroad, the current literatures lack specificity considering the diagnosis, treatment and prevention of VTE in patients with chest trauma have their own characteristics, especially for those with blunt trauma. Accordingly, China Chest Injury Research Society and editorial board of Chinese Journal of Traumatology organized relevant domestic experts to jointly formulate the Chinese expert consensus on the diagnosis, treatment and prevention of chest trauma venous thromboembolism associated with chest trauma (2022 version). This consensus provides expert recommendations of different levels as academic guidance in terms of the characteristics, clinical manifestations, risk assessment, diagnosis, treatment, and prevention of chest trauma-related VTE, so as to offer a reference for clinical application.

Huangqi Sijunzi decoction for treating cancer-related fatigue in breast cancer patients: a randomized trial and network pharmacology study / 南方医科大学学报

OBJECTIVE@#To evaluate the clinical efficacy of Huangqi Sijunzi decoction (HQSJZD) for treating cancer-related fatigue (CRF) of spleen and stomach Qi deficiency type after chemotherapy in patients with breast cancer.@*METHODS@#A total of 94 breast cancer patients who developed CRF of spleen and stomach Qi deficiency type after chemotherapy were randomized into chemotherapy group (n=47) and traditional Chinese medicine (TCM) + chemotherapy group (n=47). The patients in chemotherapy group received the AC or EC regimen and non-drug interventions including psychological counseling, and those in TCM + chemotherapy group received oral administration of HQSJZD in addition to chemotherapy for 21 days as a treatment cycle, after which improvement of fatigue was assessed using Modified Piper Fatigue Scale. The active ingredients and targets of HQSJZD were screened using the TCM System Pharmacology Analysis Platform (TCMSP); the CRF- and breast cancer-related disease targets were retrieved based on data from the GeneCards, NCBI gene and OMIM databases to construct the component-target network and the protein-protein interaction (PPI) network. GO functional enrichment analysis and Kyoto Encyclopedia of Genes and Genomes KEGG pathway enrichment analysis of the target genes were performed to construct the component-disease-pathway-target biological network. The binding strength of the major drug ingredients and CRF key targets were predicted using AutoDock software.@*RESULTS@#The scores for somatic fatigue, emotional fatigue and cognitive fatigue, along with the overall fatigue score, showed more significant improvements in TCM+chemotherapy group than in chemotherapy group (P < 0.001), and the response rate reached 89.4% in the combined treatment group. We identified 250 targets for HQSJZD, 2653 CRF-related genes, 15 329 breast cancer-related genes and 161 prescription-disease intersected targets, from which topological analysis identified 66 potential key targets. GO and KEGG enrichment analyses predicted multiple pathways related with the disease. Molecular docking results suggested that the core ingredients of HQSJZD showed high affinities to the key targets AKT1, CASP3, IL6, JUN and VEGFA, among which AKT1 might be the most important target for HQSJZD to treat CRF.@*CONCLUSION@#HQSJZD can obviously improve CRF symptoms in breast cancer patients possibly by regulating multiple signaling pathways including PI3K-Akt through AKT1.

Clinical features of children with colorectal polyps and the efficacy of endoscopic treatment: an analysis of 1 351 cases / 中国当代儿科杂志

OBJECTIVES@#To study the clinical features of children with colorectal polyps and the efficacy of endoscopic treatment.@*METHODS@#A retrospective analysis was performed on the medical data of 1 351 children with colorectal polyps who were admitted and received colonoscopy and treatment in the past 8 years, including clinical features and the pattern and outcomes of endoscopic treatment.@*RESULTS@#Among the 1 351 children, 893 (66.10%) were boys and 981 (72.61%) had an age of 2-<7 years, and hematochezia (1 307, 96.74%) was the most common clinical manifestation. Of all the children, 89.27% (1 206/1 351) had solitary polyps, and 95.77% (1 290/1 347) had juvenile polyps. The polyps were removed by electric cauterization with hot biopsy forceps (6 cases) or high-frequency electrotomy and electrocoagulation after snare ligation (1 345 cases). A total of 1 758 polyps were resected, among which 1 593 (90.61%) were pedunculated and 1 349 (76.73%) had a diameter of <2 cm. Postoperative complications included bleeding in 51 children (3.77%), vomiting in 87 children (6.44%), abdominal pain in 14 children (1.04%), and fever in 39 children (2.89%), while no perforation was observed. The children aged <3 years had the highest incidence rates of postoperative bleeding and fever (P<0.0125), and the children with a polyp diameter of ≥2 cm had significantly higher incidence rates of postoperative bleeding, vomiting, and fever (P<0.05).@*CONCLUSIONS@#Solitary polyps, pedunculated polyps, and juvenile polyps are common types of pediatric colorectal polyps. Electric cauterization with hot biopsy forceps or high-frequency electrotomy and electrocoagulation after snare ligation can effectively remove colorectal polyps in children, with good efficacy and few complications. Younger age and larger polyp diameter are associated with a higher risk of postoperative bleeding.

The application of autoantibodies detection in the early diagnosis and screening of lung cancer / 中华胸心血管外科杂志

Lung cancer is the malignant tumor with the highest morbidity and mortality worldwide, most lung cancer patients were diagnosed at an advanced stage. Using low-dose computed tomography(CT) for lung cancer screening in high-risk patients were proved to decrease lung cancer mortality and find out more early-stage patients. However, CT is of high false-positive rate which requires long-term follow-up or invasive examination to confirm the diagnosis. Serum tumor markers have become the focus of early diagnosis of lung cancer due to their characteristics of minimally invasive and good stability. Lung cancer-related antigens can be captured by the immune system to produce autoantibodies. These autoantibodies can appear in the early stage of lung cancer development with high concentration and stably exist. Therefore, the detection of serum autoantibodies can be effective in the early screening and early diagnosis of lung cancer. Here, we provide a systematic review of the production and detection methods of tumor autoantibodies and their application in the diagnosis and screening of malignant tumors, especially lung cancer.

BIX-01294 inhibits the proliferation of esophageal squamous cell carcinoma cells by inducing DNA damage and activating the mitochondrial apoptosis pathway / 中国胸心血管外科临床杂志

@#Objective    To explore the effects and molecular mechanisms of histone methylase G9a inhibitor BIX-01294 on apoptosis in esophageal squamous cell carcinoma (ESCC). Methods    MTT assay and Colony-forming Units were adopted to determine the effects of BIX-01294 on the growth and proliferation of ESCC cell lines EC109 and KYSE150. Flow cytometry was used to analyze the apoptosis status of ESCC cells after the treatment of BIX-01294. The effects of BIX-01294 treatment on the expressions of G9a catalytic product H3K9me2, DNA double-strand break (DSB) markers, and apoptosis-related proteins were detected by Western blotting. Results    BIX-01294 inhibited the growth of EC109 and KYSE150 cells in a dose-dependent manner (P<0.05), and BIX-01294 with the inhibitory concentration 50%(IC50) significantly inhibited the formation of colony (P<0.05). After 24 hours treatment of BIX-01294 (IC50), the apoptosis rate of EC109 cells increased from 11.5%±2.1% to 42.5%±5.4%, and KYSE150 cells from 7.5%±0.9% to 49.2%±5.2%(P<0.05). The expression level of the G9a catalytic product, H3K9me2, significantly decreased (P<0.05); while the expression of the DSB marker γH2AX was dramatically enhanced (P<0.05). We also found that the mitochondrial apoptosis pathway was activated and the expression levels of cleaved caspase3 and cleaved PARP were significantly elevated (P<0.05). Conclusion    BIX-01294, the inhibitor of methyltransferase G9a, prompted apoptosis in ESCC cells by inducing DSB damage and activating mitochondrial apoptosis pathway.

CTLA-4 +49 A/G Polymorphism and the Risk of Lung Cancer: a Meta-analysis / 中国肺癌杂志

BACKGROUND@#Lung cancer is one of the malignant tumors. Gene mutations associated with cellular immune function and regulating the activation and proliferation of immune cells. Several publications have explored the relationship between cytotoxic T lymphocyte antigen-4 (CTLA-4) +49 adenine (A)/guanine (G) polymorphism and susceptibility of lung cancer, but the results remain controversial. Thus, we performed this meta-analysis to derive a more comprehensive estimation of the relationship.@*METHODS@#All articles addressed lung cancer and polymorphisms of CTLA-4 were searched from the PubMed, EMBASE databases published up to June 29, 2019. Odds ratios (ORs) with 95% confidence intervals (CIs) were used to assess the strength of association. Publication bias of relevant studies was examined via Begg's test and funnel plots.@*RESULTS@#The meta-analysis included 8 case-control studies covering 4,430 lung cancer patients and 5,198 healthy controls from September 2008 to April 2020. The overall eligible data indicated that CTLA-4 +49A/G polymorphisms did not correlate with the elevated lung cancer risk in all genetic comparison models (dominant model: OR=1.037, 95%CI: 0.925-1.161; recessive model: OR=0.968, 95%CI: 0.888-1.055; allele model: OR=0.992, 95%CI: 0.933-1.054; homozygous model: OR=0.980, 95%CI: 0.857-1.121; heterozygous model: OR=1.023, 95%CI: 0.906-1.154). In further stratified analyses, CTLA-4 +49A/G polymorphism was found to be significantly associated with susceptibility to NSCLC in these models (dominant model: OR=1.404, 95%CI: 1.074-1.836; allele model: OR=1.273, 95%CI: 1.034-1.565; homozygous model: OR=1.553, 95%CI: 1.044-2.310; heterozygous model: OR=1.308, 95%CI: 1.062-1.611).@*CONCLUSIONS@#CTLA-4 +49A/G polymorphism were not associated with the risk of lung cancer but might be a risk factor only in NSCLC.

Clinical Recommendations for Perioperative Immunotherapy-induced Adverse Events in Patients with Non-small Cell Lung Cancer / 中国肺癌杂志

BACKGROUND@#Perioperative treatment has become an increasingly important aspect of the management of patients with non-small cell lung cancer (NSCLC). Small-scale clinical studies performed in recent years have shown improvements in the major pathological remission rate after neoadjuvant therapy, suggesting that it will soon become an important part of NSCLC treatment. Nevertheless, neoadjuvant immunotherapy may be accompanied by serious adverse reactions that lead to delay or cancelation of surgery, additional illness, and even death, and have therefore attracted much attention. The purpose of the clinical recommendations is to form a diagnosis and treatment plan suitable for the current domestic medical situation for the immune-related adverse event (irAE).@*METHODS@#This recommendation is composed of experts in thoracic surgery, oncologists, thoracic medicine and irAE related departments (gastroenterology, respirology, cardiology, infectious medicine, hematology, endocrinology, rheumatology, neurology, dermatology, emergency section) to jointly complete the formulation. Experts make full reference to the irAE guidelines, large-scale clinical research data published by thoracic surgery, and the clinical experience of domestic doctors and publicly published cases, and repeated discussions in multiple disciplines to form this recommendation for perioperative irAE.@*RESULTS@#This clinical recommendation covers the whole process of prevention, evaluation, examination, treatment and monitoring related to irAE, so as to guide the clinical work comprehensively and effectively.@*CONCLUSIONS@#Perioperative irAE management is an important part of immune perioperative treatment of lung cancer. With the continuous development of immune perioperative treatment, more research is needed in the future to optimize the diagnosis and treatment of perioperative irAE.

Laparoscopic circular stapled gastrointestinal anastomosis using novel device of sealed cap access after total laparoscopic gastrectomy / 中华胃肠外科杂志

Intracorporeal classic gastrointestinal anastomosis using circular stapler in totally laparoscopic gastrectomy (TLG) for gastric cancer requires intracorporeal anvil placement and suitable access for introduction of the circular stapler to the abdominal cavity without gas leak. The novel techniques for anvil placement have been updated, but there is no progress for proper access for circular stapler. In the study, intracorporeal circular-stapled gastrointestinal anastomosis were successfully accomplished using a novel device of sealed cap access with a central hole (WLB-60/70-60/100, Wuhan Widerep Medical Instrument Co.,Ltd, China) customized to the incision protection retractor for the simple and accessible introduction of the circular stapler and anvil under the optimal maintenance of pneumoperitoneum pressure in TLG. In these 3 cases, there was no gas leakage and the pneumoperitoneum was well maintained when performing the gastrointestinal anastomosis, and there was no transition to laparotomy or other anastomosis techniques. The result suggests that the sealed cap access could be a novel choice for introduction of the circular stapler to the abdominal cavity in order to obtain laparoscopic circular-stapled gastroin-testinal anastomosis in TLG.

@#Objective    To investigate the safety and efficiency of robotic lung segmentectomy. Methods    The clinical data of 110 patients receiving robotic or thoracoscopic segmentectomy in our hospital between June 2015 and June 2019 were retrospectively analyzed. The patients were divided into a robotic group [n=50, 13 males and 37 females aged 53.0 (46.0, 60.0) years] and a thoracoscopic group [n=60, 21 males and 39 females aged 61.0 (53.0, 67.0) years]. A propensity score-matched analysis was adopted to compare the perioperative data between the two groups. Results    After the propensity score-matched analysis, 34 patients were included in each group. In comparison with the thoracoscopic group, patients in the robotic group had less blood loss [40.0 (20.0, 50.0) mL vs. 60.0 (40.0, 80.0) mL, P<0.001], more stations of lymph node dissection [7.0 (6.0, 8.0) vs. 4.0 (3.0, 6.0), P<0.001], larger number of lymph node dissection [15.0 (11.0, 21.0) vs. 10.0 (6.0, 14.0), P=0.002], and a higher total cost of hospitalization [97.0 (92.0, 103.0) thousand yuan vs. 54.0 (42.0, 59.0) thousand yuan, P<0.001]. Conclusion    In contrast with the thoracoscopic segmentectomy, robotic segmentectomy has a similar operative safety, but less blood loss and a thorough lymphadenectomy.
