"Global cancer statistics 2022" based on the latest GLOBCAN data from the International Agency for Research on Cancer (IARC) was recently released, providing a systematic analysis of the incidence and mortality of 36 types of cancer across 185 countries worldwide. The international burden of cancer is expected to continue to increase over the next 30 years, posing a severe public health and social challenge for many countries, including China. This article offers a key point interpretation of the "Global cancer statistics 2022", focusing on the evolution of cancer epidemiology and future development trends. The aim is to broaden the international perspective on cancer prevention and treatment, with the hope of providing reference and guidance for cancer prevention and treatment efforts in our country.

Based on the"You Gu Wu Yun"theory in traditional Chinese medicine(TCM),this paper believes that"Gu"in"You Gu Wu Yun"is extended to"state"from the perspective of"TCM state".In order to avoid the adverse reactions of TCM,the macro,meso,and micro three views should be used together,and macro,meso,and micro parameters should be integrated.We should also carefully identify the physiological characteristics,pathological characteristics,constitution,syndrome,and disease of human body by combining qualitative and quantitative method,highlighting the relationship between the prescription and the"state".The correspondence between prescription and the"state"will reduce the risk of adverse reactions of TCM.In this paper,we hope to focus on the guiding role of the"You Gu Wu Yun"theory in TCM research,to give full play to the characteristics and advantages of TCM,and to dialectically treat the role of TCM.

In order to meet the accuracy requirements of hospitals for abnormal detection of fetal monitor data,a hospital fetal monitor data anomaly detection method based on Euclidean distance was proposed.In this method,according to the abnormal detection method of fetal monitor data in hospitals,the ultrasound Doppler detector was used to collect fetal heart rate signal data,and the fetal heart rate signal denoising method based on adaptive filtering was used to remove the noise components of the collected fetal heart rate signal.The denoised fetal heart rate signal was used as the identification sample of the abnormal fetal heart rate signal identification method based on Euclidean distance method.The Euclidean distance Euclidean distance between the denoised fetal heart rate signal and the normal fetal heart rate signal was analyzed by combining the Euclidean distance method and the strong classifier to analyze whether the virtual sinusoidal distance between the denoised fetal heart rate signal and the normal fetal heart rate signal was greater than the tuned Euclidean distance threshold.Fetal heart rate signal samples greater than the threshold were classified and diagnosed as abnormal monitoring data.The fetal heart rate information collected by the fetal monitor in the hospital was accurate,and the abnormal detection results were valid and reliable.

Objective:To analyze the binding ability of motifs in the serine/threonine kinase StkP extracellular region (EC-StkP) of Streptococcus pneumoniae to β-lactam antibiotics. Methods:Three motifs (SXXK) in the EC-StkP were mutated into AXXA, respectively or simultaneously. Four mutant plasmids (EC- stkp-AXXA1, EC- stkp-AXXA2, EC- stkp-AXXA3 and EC- stkp-AXXA4) were transfected into recipient cells for cloning and expression. SDS-PAGE combined with gel image analysis was used to detect the expression of the recombinant mutant proteins (EC-rStkP-AXXA1, EC-rStkP-AXXA2, EC-rStkP-AXXA3 and EC-rStkP-AXXA4). The expressed mutated proteins were extracted and purified by Ni-NTA affinity chromatography. The binding abilities of the mutant proteins to penicillin (PCN) and cefotaxime (CTX) were detected by isothermal titration calorimetry (ITC 200) and surface plasmon resonance (Biacore t200). Results:PCN and CTX could not bind to the expressed proteins with mutations in the first or the third motif (EC-rStkP-AXXA1, EC-rStkP-AXXA3, EC-rStkP-AXXA4). EC-rStkP-AXXA2 could weakly bind to CTX, but not to PCN.Conclusions:All three motifs in the EC-StkP of Streptococcus pneumoniae could bind to β-lactam antibiotics with the first and the third motifs being more important.

Liver failure is a syndrome of severe liver diseases commonly seen in clinical practice, and it has a high mortality rate and thus becomes one of the critical diseases in internal medicine. Massive hepatocyte death and the extent of hepatocyte death exceeding the liver’s regenerative capacity are considered the core events in the development and progression of liver failure, and direct injury and immune-mediated inflammatory injury are the two main factors in this process. An increasing number of evidence has shown that host immune response and inflammatory cascade play an important role in the pathogenesis of liver failure. This article reviews the mechanism of action of immunoregulation (congenital and adaptive) and inflammatory injury (inflammation inducers, receptor cells, and inflammatory mediators) in the process of hepatic failure, as well as the interactions between immune response and immune cells and between inflammatory response and inflammatory factors, in order to help understand the pathogenesis of liver failure and provide new ideas for the diagnosis and treatment of liver failure and drug research and development.

Objective To develop an easy-to-use nomogram to assist clinicians in predicting major postoperative morbidity in those non-small-cell lung canccr patients who underwent VATS lobectomy.Methods A perspective multi-center study was developed to analyze the major postoperative complications of 612 non-small-cell lung cancer patients who underwent VATS lobectomy.Muhivariable logistic regression was used to model postoperative morbidity and built the nomogram to accurately predict the major complications.Results There were 606 (99％) survivors and 6 (1％) mortality.A total of 32 patients suffered from major complications.Using logistic regression to predict major complications,preoperative model for ASA score,age ≥70 years and operation time ＞ 150 nin were found to be the significant predictors(P ＜ 0.05) of morbidity and were included in our model.Conclusion We propose a nomogram to enable clinicians to better estimate morbidity in patients with VATS lobectomy.

Objective To investigate the effect of liver kinase B1(LKB1) on the radiosensitivity of subcutaneous xenograft tumor of lung cancer H460 cells in nude mice.Methods Human lung cancer H460 cells were implanted into female nude mice (BALB/c-nu) to establish a subcutaneous xenograft tumor model of lung cancer.A total of 24 female nude mice in which the model was successfully established were equally and randomly divided into four groups:pEGFP-Ctrl plasmid (empty vector plasmid) group, irradiation (IR)+pEGFP-Ctrl plasmid group, pEGFP-LKB1 plasmid (overexpressing LKB1) group, and IR+pEGFP-LKB1 plasmid group.The growth of xenograft tumors was observed and the tumor inhibition rate and enhancement factor (EF) were calculated.The expression of LKB1 in each group was measured by immunohistochemistry and Western blot to analyze the relationship between LKB1 and radiosensitivity.Results Compared with the pEGFP-Ctrl plasmid group, the IR+pEGFP-Ctrl plasmid group, pEGFP-LKB1 plasmid group, and IR+pEGFP-LKB1 plasmid group showed varying degrees of inhibition of tumor growth, particularly in the IR+pEGFP-LKB1 plasmid group, and the tumor inhibition rates were 31.30%, 14.78%, and 43.48%, respectively.The EF of LKB1 in the IR+pEGFP-LKB1 plasmid group was 1.18.The immunohistochemistry and Western blot showed that LKB1 could be effectively expressed in the pEGFP-LKB1 plasmid group and IR+pEGFP-LKB1 plasmid group, but not in the other two groups.Conclusions The subcutaneous xenograft tumor model of human lung cancer H460 cells has been successfully established in nude mice.LKB1 has a radiosensitizing effect on the subcutaneous xenograft tumor of lung cancer H460 cells in nude mice.

Background: Bone metastases are common in patients with advanced cancer. Bisphosphonates (BPs) could prevent or delay the development of skeleton-related events (SREs). The present study aimed to identify the clinical features of and treatment strategies for Chinese patients with bone metastases. Methods: Consecutive cancer patients who had bone metastases and received BP treatment were enrolled. A ques-tionnaire was developed to collect the patients’clinical data, as well as information on the diagnosis and manage-ment of bone metastases. Physicians’awareness of the guidelines and knowledge of the application of BP were also assessed. Results: A total of 3223 patients with lung cancer (36.5%), breast cancer (30.9%), prostate cancer (8.5%), and gas-trointestinal cancer (5.7%) were included in this study. The sites of bone metastases were the thoracic spine (56.0 %), lumbar spine (47.1%), ribs (32.6%), and pelvis (23.2%). The SRE frequency was the highest in patients with multiple myeloma (36.6%), followed by those with lung cancer (25.9%), breast cancer (20.2%), prostate cancer (18.2%), and gas-trointestinal cancer (17.3%). Irradiation to the bone was the most frequent SRE (58% in lung cancer patients, 45% in breast cancer patients, and 48% in prostate cancer patients). Our survey also showed that 45.5% of patients received BP within 3 months after their diagnosis of bone metastases, whereas the remaining 54.5% of patients did not receive BP treatment until at least 3 months after their diagnosis of bone metastases. The SRE frequency in the former group was significantly lower than that in the latter group (4.0% vs. 42.3%, P < 0.05). In patients with more than 6 months of continuous BP treatment, the mean time to the first SRE was significantly longer than that in patients with less than 6 months of continuous BP treatment (7.2 vs. 3.4 months, P < 0.05). In addition, 12.2% of the physicians were not aware of the efcacy of BP in preventing and delaying SRE. Only half (52.3%) of the physicians agreed that the BP treatment should persist for at least 6 months unless it was intolerable. Conclusions: Our study suggested that prompt and persistent BP treatment was associated with a reduced risk of SREs. However, our survey also revealed that the proper application of BP was not as common as expected in China.

Objective To analyze the clinical characteristics of Klebsiella pneumoniae infection in preterm infants. Methods Clinical data of 75 preterm infants infected with Klebsiella pneumoniae treated in BaYi Children's Hospital from February 6,2008 to February 10,2010 were retrospectively analyzed.The difference of auxiliary examination between early-onset and late-onset infection group were compared by two independent samples t test.Spearman correlation analysis and non-conditional Logistic regression analysis were used to analyze the high risk factors and the prognostic factors of Klebsiella pneumoniae infection in preterm infants. Results The incidence of Klebsiella pneumoniae infection was 2.8％ (75/2721) in preterm infants,and the mortality rate was 9.3％ (7/75). There were 71 cases of Klebsiella pneumoniae sepsis and 4 cases of Klebsiella pneumoniae pneumonia.Among 75 cases,63 cases were early-onset infection (onset age≤72 h) and 12 were late-onset infection (onset age＞72 h).All patients presented with poor response,heart rate during quiet sleep ＞ 160/min and low oxygen saturation.The mean corpuscular volume and mean corpuscular hemoglobin concentration in early-onset Klebsiella pneunoniae infection cases were higher than those in late-onset neonates [(128.87±24.60) fl vs (113.72±13.54) fl,t=-2.07,P＜0.05and (38.11±2.15) pg vs (36.98±1.05) pg,t=-2.76,P＜0.05].Low birth weight and caesarean section were associated with early-onset Klebsiella pneumoniae sepsis (r=0.250 and -0.240,P＜0.05). The prognosis of Klebsiella pneumoniae infection was associated with hospital stay and duration of premature rupture of membranes (r=0.368 and 0.318,P＜0.05). Conclusions There were no specific clinical manifestations for Klebsiella pneumoniae infection in preterm infants.Preterm infants with low birth weight,long duration of premature rupture of membranes,delivered by caesarean section and received invasive operation are likely to develop Klebsiella pneumoniae infection.
