Characteristics of STAT Family Association with Breast Cancer and Intervention Effect of Traditional Chinese Medicine / 中国实验方剂学杂志

As the pace of society increases and lifestyles change， the incidence and mortality rates of breast cancer continue to rise. Targeted therapies are now promising in the treatment of breast cancer， and a variety of protein targets have been identified to play an important role in the development of breast cancer. Among them， signal transducer and activator of transcription （STAT） proteins constitute a crucial group that serves as important targets for transducing cellular transcriptional information， which can regulate downstream cell proliferation， apoptosis， cell migration， invasion， angiogenic factors， etc. and then affect the progression of breast cancer. The STAT family is closely associated with the inflammatory response to tumors and plays a landmark role in tumor development as well as in diagnosis and prognosis. The "inflammation-cancer" transformation refers to the process in which the inflammatory microenvironment caused by uncontrolled inflammation promotes normal cells to become cancerous. According to the theory of Chinese medicine， "heat toxicity" in "cancer toxicity" corresponds to inflammation， which is closely related to tumor development. As a major link associated with the inflammatory response， the STAT family has a promising role in the development and treatment of a variety of tumors， but its relevance to breast cancer remains inadequately explored. Chinese medicine has been shown to have good efficacy in the prevention and treatment of breast cancer， and some current studies have shown that the active ingredients and compounds of Chinese medicine have certain intervention effects on breast cancer-related STAT proteins， but there has not been a systematic review. In order to better sort out and summarize the studies on the effects of Chinese herbal medicines based on the STAT family interventions in breast cancer， this paper reviewed the studies on Chinese herbal medicines acting on the STAT family in recent years， aiming to provide new ideas for clinical applications in breast cancer and to provide thoughts for the development of STAT protein-based drugs.

Expression change and role of sex determining region box transcription factor 2 mRNA and the non-coding RNA in the hepatocyte stem changes during the rat liver regeneration / 解剖学报

Objective To explore the role pathway and pattern of the sex determining region box transcription factor 2 (SOX2) and its mRNA interaction with microRNA(miRNAs, miR) and circular RNA(circRNA) at 0 hour and 2 hours in the rat liver regeneration. Methods The rat 2/3 hepatectomy (partial hepatectomy, PH) model was prepared as described by Higgins, the hepatocytes were isolated according to the method of Smedsrod et al, the expression changes of mRNA, miRNA and circRNA [together named as competing endogenous RNAs(ceRNA)] were detected by the large-scale quantitative detection technology, the interaction network of ceRNA was constructed by Cytoscape 3.2 software, and their correlation in expression and role were analyzed by ceRNA comprehensive analysis. Results It was found that at the 0 hour and 2 hours after PH, the ratio value of SOX2 mRNA shows 1.00±0.09 and 2.15±0.48, miR-3558-3p displays 4.53± 0.10 and 0.81±0.16, circRNA_18404 shows 1.24±0.04 and 11.10±0.57, circRNA_18045 displays 1.97±0.47 and 4.44± 0.23. At the same time, the eight kinds of cell dedifferentiation-related genes AT-rich interaction domain 5A (ARID5A), activating transcription factor 3 (ATF3), BTG anti-proliferation factor 2 (BTG2), etc, which are prometed in expression by SOX2, were down-regulated at 0 h after PH, but the cell differentiation-related genes interferon regulatory factor 6 (IRF6) and somatostatin (SST), which are inhibited in expression by SOX2, were up-regulated at 0 hour after PH. On the other hand, the eight kinds of cell dedifferentiation-related genes ARID5A, ATF3, BTG2, etc, which are promoted in expression by SOX2, were up-regulated at 2 hours after PH, but the cell differentiation-related gene SST, which is inhibited in expression by SOX2, was down-regulated, and IRF6 had no meaningful changes in expression at 2 hours after PH. Conclusion The correlation in expression and role of the miRNA, which are inhibited by circRNA, SOX2, its mRNA is inhibited by miRNA, and the cell stem-related genes, which are regulated by SOX2, are helpful for the hepatocyte to be in differentiation state at 0 hour after PH and to be in stem state at 2 hours after PH.

Current status and trend of acupuncture-moxibustion for myofascial pain syndrome: a visual analysis of knowledge graph based on CiteSpace and VOSviewer / 中国针灸

Bibliometric and scientific knowledge graph methods were used to analyze the research status and hot spots of acupuncture-moxibustion in treatment of myofascial pain syndrome (MPS) and explore its development trend. The articles of both Chinese and English versions relevant to MPS treated by acupuncture-moxibustion were searched in CNKI, VIP, Wanfang, SinoMed and WOS from the database inception to March 20, 2023. Using Excel2016, CiteSpace6.2.R2 and VOSviewer1.6.18, the visual analysis was conducted by means of the cooperative network, keyword co-occurrence, keyword timeline, keyword emergence, etc. From Chinese databases and WOS database, 910 Chinese articles and 300 English articles were included, respectively. The annual publication volume showed an overall rising trend. Literature output of English articles was concentrated in Spain, China, and the United States, of which, there was less cross-regional cooperation. In the keyword analysis, regarding acupuncture-moxibustion therapy, Chinese articles focused on "acupuncture", "electroacupuncture" and "acupotomy"; while, "dry needling" and "injection" were dominated for English one. Clinical study was the current hot spot in Chinese databases, in comparison, the randomized controlled double-blind clinical trial was predominant in WOS. Both Chinese and English articles were limited in the report of mechanism research. The cooperation among research teams should be strengthened to conduct comparative research, dose-effect research and effect mechanism research with different methods of acupuncture-moxibustion involved so that the evidences can be provided for deeper exploration.

Clinical value of plasma scaffold protein SEC16A in evaluating hepatitis B-related liver cirrhosis and hepatocellular carcinoma / 中华肝脏病杂志

Objective: To investigate the clinical value of plasma scaffold protein SEC16A level and related models in the diagnosis of hepatitis B virus-related liver cirrhosis (HBV-LC) and hepatocellular carcinoma (HBV-HCC). Methods: Patients with HBV-LC and HBV-HCC and a healthy control group diagnosed by clinical, laboratory examination, imaging, and liver histopathology at the Third Hospital of Hebei Medical University between June 2017 and October 2021 were selected. Plasma SEC16A level was detected using an enzyme-linked immunosorbent assay (ELISA). Serum alpha-fetoprotein (AFP) was detected using an electrochemiluminescence instrument. SPSS 26.0 and MedCalc 15.0 statistical software were used to analyze the relationship between plasma SEC16A levels and the occurrence and development of liver cirrhosis and liver cancer. A sequential logistic regression model was used to analyze relevant factors. SEC16A was established through a joint diagnostic model. Receiver operating characteristic curve was used to evaluate the clinical efficacy of the model for liver cirrhosis and hepatocellular carcinoma diagnosis. Pearson correlation analysis was used to identify the influencing factors of novel diagnostic biomarkers. Results: A total of 60 cases of healthy controls, 60 cases of HBV-LC, and 52 cases of HBV-HCC were included. The average levels of plasma SEC16A were (7.41 ± 1.66) ng/ml, (10.26 ± 1.86) ng/ml, (12.79 ± 1.49) ng /ml, respectively, with P < 0.001. The sensitivity and specificity of SEC16A in the diagnosis of liver cirrhosis and hepatocellular carcinoma were 69.44% and 71.05%, and 89.36% and 88.89%, respectively. SEC16A, age, and AFP were independent risk factors for the occurrence of HBV-LC and HCC. SAA diagnostic cut-off values, sensitivity, and specificity were 26.21 and 31.46, 77.78% and 81.58%, and 87.23% and 97.22%, respectively. The sensitivity and specificity for HBV-HCC early diagnosis were 80.95% and 97.22%, respectively. Pearson correlation analysis showed that AFP level was positively correlated with alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBil), and γ-glutamyltransferase (GGT) with P < 0.01, while the serum SEC16A level was only slightly positively correlated with ALT and AST in the liver cirrhosis group (r = 0.268 and 0.260, respectively, P < 0.05). Conclusion: Plasma SEC16A can be used as a diagnostic marker for hepatitis B-related liver cirrhosis and hepatocellular carcinoma. SEC16A, combined with age and the AFP diagnostic model with SAA, can significantly improve the rate of HBV-LC and HBV-HCC early diagnosis. Additionally, its application is helpful for the diagnosis and differential diagnosis of the progression of HBV-related diseases.

The clinical value of serum GPC3 level in predicting recurrence of patients with primary hepatocellular carcinoma / 中华预防医学杂志

Objective: To investigate the clinical value of serum glypican-3 (GPC3) detection in predicting recurrence of primary hepatocellular carcinoma (HCC). Methods: Through univariate and multivariate logistic regression analysis, the patients pathologically diagnosed with HCC in our hospital from March 2019 to January 2021 were enrolled as the experimental group (n=113), and patients with follow-up time longer than 6 months were included in the prognosis group(n=64). At the same time,20 healthy individuals and 20 individuals with benign liver disease from the physical examination center were enrolled by simple random sampling as control group (n=40). The serum GPC3 and alpha-fetoprotein (AFP) levels were respectively detected by ELISA and chemiluminescence. Then, the study explored the influential factors of the recurrence in HCC patients and constructed the HCC-GPC3 recurrence predicting model by logistic regression. Results: In the research, the sensitivity of GPC3 for the diagnosis of HCC was 61.95% (70/113) and AFP was 52.21% (59/113), meanwhile, the specificity of GPC3 could reach 87.50% (35/40) and AFP was 90.00% (36/40),respectively; The serum GPC3 levels of HCC patients with progressive stage, tumor size≥3 cm, vascular cancer thrombosis and portal venous thromboembolism were significantly higher than that of HCC patients with early stage, tumor size<3 cm, vascular cancer thrombosis and portal venous thromboembolism (Z=2.677, 2.848, 2.995, 2.252, P<0.05), independent of different ages, presence or absence of ascites, peritoneal metastasis, cirrhosis, intrahepatic metastasis (Z=-1.535, 1.011, 0.963, 0.394, 1.510, P>0.05), respectively. Univariate analysis showed that there were no statistically significant differences between the recurrence group and the non-recurrence group in terms of different age, tumor size, presence or absence of vascular cancer thrombosis, ascites, peritoneal metastasis, cirrhosis and AFP levels (χ2=2.012, 0.119, 2.363, 1.041, 0.318, 0.360, Z=0.748, P>0.05); The ratio of those with the progressive stage, portal venous thromboembolism and intrahepatic metastasis and GPC3 levels were all higher in the recurrence group than in the non-recurrence group (χ2=4.338, 11.90, 4.338, Z=2.805, P<0.05).Including the above risk factors in the logistic regression model, the logistic regression analysis showed that the stage, the presence of portal venous thromboembolism,intrahepatic metastasis and GPC3 levels were correlated with the prognosis recurrence of HCC patients (Wald χ2 =4.421, 5.681, 4.995, 4.319, P<0.05), and the HCC-GPC3 recurrence model was obtained as: OcScore=-2.858+1.563×[stage]+1.664×[intrahepatic metastasis]+2.942×[ portal venous thromboembolism]+0.776×[GPC3]. According to the receiver operating characteristic curve(ROC), the area under the curve(AUC)of the HCC-GPC3 prognostic model was 0.862, which was better than that of GPC3 alone (AUC=0.704). The cut-off value of model SCORE was 0.699 (the cut-off value of GPC3 was 0.257 mg/L), furthermore, the total sensitivity and specificity of model were 83.3% and 82.4%, which were better than those of GPC3(60.0% and 79.4%).Kaplan-Meier showed that the median PFS was significantly shorter in HCC patients with high GPC3 levels (≥0.257 mg/L) and high values of the model SCORE (≥0.700) (χ2=12.73, 28.16, P<0.05). Conclusion: Besides diagnosing of HCC, GPC3 can may be an independent risk indicator for the recurrence of HCC and can more efficiently predicting the recurrence of HCC patients when combined with the stage, the presence or absence of intrahepatic metastasis and portal venous thromboembolism.

Protective effect of chrysin regulates AMPK-NLRP3 signaling mediated pyroptosis to alleviate hepatic fibrosis / 药学学报

This study investigated the protective effect of chrysin on hepatic fibrosis by regulating AMP-activated kinase (AMPK)-NOD-like receptor protein 3 (NLRP3) mediated pyroptosis pathway. The hepatic fibrosis model of mice was established by thioacetamide (TAA) in vivo. Except the control and chrysin alone groups, the mice were injected intraperitoneally with TAA at 100 mg·kg-1, three times per week for the first week. From the 2nd to 5th week, mice were injected intraperitoneally with TAA at 200 mg·kg-1, three times per week for the next 4 weeks. Chrysin groups were intragastrically administrated once per day to 5th week. The histopathological changes were detected by HE and Masson staining. The levels of serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) were assessed by the kits. All animal experiments were approved by the Medical Ethics Committee of Affiliated Zhongshan Hospital of Dalian University (DWLL2019060). LX-2 cells were stimulated by (transforming growth factor-β, TGF-β) in vitro. The protein expressions of AMPKα, p-AMPKα, NLRP3, cysteinyl aspartate specific proteinase-1 (caspase-1), gasdermin D (GSDMD) were detected by Western blot, and the mRNA levels of collagen-Ι, α-smooth muscle actin (α-SMA), interleukin-1β (IL-1β), IL-18, caspase-1, GSDMD were analysis by reverse transcription-polymerase chain reaction (RT-PCR). Chrysin attenuated the increases in serum AST and ALT levels in the TAA group, while significantly improved the changes of liver morphology, reduced liver tissue inflammatory cell infiltration and inhibited collagens deposition. Compared with TAA group, chrysin effectively activated AMPKα phosphorylation and inhibited hepatic NLRP3 inflammasome activation. Additionally, the protein expressions and mRNA levels of IL-1β, IL-18, caspase-1 and GSDMD in chrysin groups were decreased. Chrysin inhibited the expressions of collagen-Ι and α-SMA, enhanced the phosphorylation of AMPKα, and decreased the expressions of NLRP3 and GSDMD. Therefore, chrysin may inhibit inflammatory injury and pyroptosis possibly by activating AMPK and inhibiting NLRP3 inflammasome to alleviate hepatic fibrosis.

2023 China Guidelines for Lipid Management / 老年心脏病学杂志（英文版）

Atherosclerotic cardiovascular disease (ASCVD) is the leading cause of death among urban and rural residents in China, and elevated low-density lipoprotein cholesterol (LDL-C) is a risk factor for ASCVD. Considering the increasing burden of ASCVD, lipid management is of the utmost importance. In recent years, research on blood lipids has made breakthroughs around the world, hence a revision of China guidelines for lipid management is imperative, especially since the target lipid levels in the general population vary in respect to the risk of ASCVD. The level of LDL-C, which can be regarded as appropriate in a population without frisk factors, can be considered abnormal in people at high risk of developing ASCVD. As a result, the "Guidelines for the prevention and treatment of dyslipidemia" were adapted into the "China Guidelines for Lipid Management" (henceforth referred to as the new guidelines) by an Experts' committee after careful deliberation. The new guidelines still recommend LDL-C as the primary target for lipid control, with CVD risk stratification to determine its target value. These guidelines recommend that moderate intensity statin therapy in adjunct with a heart-healthy lifestyle, be used as an initial line of treatment, followed by cholesterol absorption inhibitors or/and proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors, as necessary. The new guidelines provide guidance for lipid management across various age groups, from children to the elderly. The aim of these guidelines is to comprehensively improve the management of lipids and promote the prevention and treatment of ASCVD by guiding clinical practice.

Consistency evaluation of target heart rate determined by anaerobic threshold and by resting heart rate in patients with coronary artery disease after percutaneous coronary intervention / 中华心血管病杂志

Objective: To evaluate the consistency on the determination of target heart rate by simple calculation method based on resting heart rate and by anaerobic threshold method in cardiopulmonary exercise test (CPET) for patients with coronary artery disease after percutaneous coronary intervention (PCI). Methods: This study was a diagnostic test. Patients with coronary artery disease who underwent the first PCI in the Department of Cardiology of Peking University People's Hospital from October 2011 to April 2021 were enrolled. Patients were further divided into subgroups according to gender, age (<60 years group and ≥60 years group), with or without myocardial infarction history (myocardial infarction group and angina pectoris group) and whether β blockers were applied. The general clinical data of patients, resting heart rate (RHR) and anaerobic threshold heart rate in CPET were collected through the electronic medical record system. The simple target rate (RHR plus 20 or 30 bpm) and the target rate calculated by anaerobic threshold (anaerobic threshold heart rate minus 10 bpm) were both calculated in each patient. Consistency test of target heart rate derived by above the two methods was shown by intra-class correlation (ICC) and Bland-Altman plots. Results: A total of 439 patients were included, age was (56.2±8.8) years, body mass index was (25.77±2.34) kg/m2, there were 382 males (87.0%). The target heart rate determined by anaerobic threshold method was (90.0±11.8)bpm, and the simple target heart rate determined by RHR plus 20 bpm was (91.0±8.4)bpm. There was no significant difference on the target heart rate derived from the two calculation methods (P=0.091). The simple target heart rate determined by RHR plus 30 bpm was (101.0±8.4)bpm, which was significant higher than that determined by anaerobic threshold method (P<0.001). In the following analysis, RHR plus 20 bpm was defined as the simple target heart rate. The ICC value of target heart rate determined by anaerobic threshold and resting rate plus 20 bpm was 0.529(95%CI 0.458-0.593, P<0.001). Bland-Altman plots analysis showed that the ratio of the simple target heart rate and the target heart rate determined by anaerobic threshold method was 1.03±0.11 and the 95% limits of agreement (LOA) were 0.812-1.245. In the subgroup of patients aged<60 years (n=247), the ICC value was 0.492, the ratio by Bland-Altman plots analysis was 1.02±0.11 and LOA was 0.814-1.234; in the subgroup of patients aged ≥60 years (n=192), the ICC value was 0.566, the ratio by Bland-Altman plots analysis was 1.03±0.11 and LOA was 0.810-1.260. In male subgroup(n=382), the ICC value was 0.540, the ratio by Bland-Altman plots analysis was 1.03±0.11 and LOA was 0.813-1.246; in female subgroup(n=57), the ICC value was 0.445, the ratio by Bland-Altman plots analysis was 1.03±0.11 and LOA was 0.810-1.240.In myocardial infarction subgroup (n=186), the ICC value was 0.568, the ratio by Bland-Altman plots analysis was 1.02±0.11 and LOA was 0.810-1.227; in angina pectoris subgroup (n=253), the ICC value was 0.495, the ratio by Bland-Altman plots analysis was 1.04±0.11 and LOA was 0.813-1.260. In the subgroup of patients with β blockers (n=353), the ICC value was 0.520, the ratio by Bland-Altman plots analysis was 1.03±0.11 and LOA was 0.810-1.252; in the subgroup of patients without β blockers (n=86), the ICC value was 0.570, the ratio by Bland-Altman plots analysis was 1.02±0.10 and LOA was 0.821-1.219. Conclusions: The simple target heart rate determined by RHR plus 20 bpm is consistent with the target heart rate determined by anaerobic threshold in patients with coronary artery disease after PCI. But the simple target heart rate determined by RHR plus 20 bpm can't replace the target heart rate determined by anaerobic threshold in this patient cohort.

Comparison of aspirin and low molecular weight heparin in pulmonary lobectomy after percutaneous coronary intervention / 中华胸心血管外科杂志

Objective:To compare the clinical application of aspirin and low molecular weight heparin in pulmonary lobectomy after percutaneous coronary intervention(PCI), and to explore the effect of aspirin monotherapy in anti-platelet therapy.Methods:From January 2018 to December 2019, the clinical data of 48 patients with coronary atherosclerotic heart disease(coronary heart disease) who underwent lobectomy in the Thoracic Surgery Department of Beijing Anzhen Hospital within 12 months after PCI were retrospectively analyzed. There were 37 males and 11 females. The age ranged from 41 to 76(67.6±10.4) years. There were 22 cases with hypertension, 18 cases with diabetes and 2 cases with cerebrovascular disease. Iliac artery stents were inserted in 2 cases and vertebral artery stents in 1 case. Preoperative atrial fibrillation in 2 cases. There were 46 patients with gradeⅠand 2 patients with gradeⅡcardiac function(NYHA). According to the preoperative antiplatelet treatment, the patients were divided into aspirin group(25 cases) and low molecular weight heparin group(LMWH group, 23 cases). In the aspirin group, clopidogrel or ticagrelor was stopped 5 days before lobectomy, and aspirin single drug antiplatelet therapy was used, orally 100 mg every day until the morning of operation. In the LMWH group, aspirin, clopidogrel or ticagrelor were stopped 7 days before surgery, and 0.6 ml LMWH calcium was injected subcutaneously, once every 12 hours, and stopped 12 hours before surgery. Perioperative clinical data of the two groups were recorded and analyzed, and major adverse cardiac event(MACE) and bleeding events were observed.Results:There was no death in all groups. MACE and bleeding occurred in 1 case respectively in LMWH group. There were no significant differences between the two groups in length of hospital stay, duration of operation, diameter of lesion, total postoperative thoracic drainage and retention time of thoracic drainage tube( P>0.05). The intraoperative blood loss and chest drainage in the aspirin group were significantly lower than those in the LMWH group in the first 3 days after surgery, with statistical significance( P<0.05). Conclusion:The incidence of MACE increases after lobectomy for coronary heart disease within 12 months after PCI, and aspirin monotherapy is safe and effective in antiplatelet therapy.

Methods: Retrospective review of the clinical data of 63 HIV-infected patients with DLBCL diagnosed at Chongqing University Cancer Hospital between July 2008 and August 2021. The Kaplan-Meier method was used to calculate survival curves, and the log-rank test method was used to compare survival between groups. The Cox proportional hazards model was used for multivariate analysis. Results: In 63 patients with HIV-associated DLBCL, 57 (90.5% ) were men, and the median age was 49 (23-87) years. The most common pathological subtype was the germinal center B-cell-like lymphoma (74.6% ) ; 46.0% (29/63) were combined with extranodal lesions. Seventeen of 63 (27.0% ) patients had large masses (≥7.5 cm) . Twenty of 63 (31.7% ) patients had B symptoms. The median CD4(+) T cell count was 203 (4-1022) ×10(6)/L. A total of 49% (25/51) patients had CD4(+) cell count <200×10(6)/L, 56.9% (33/58) had high (3-5) International Prognostic Index (IPI) scores, and 43.1% (25/58) had low (0-2) IPI scores. Further, 78% (46/59) were diagnosed with Ann Arbor Stage Ⅲ/Ⅳ, and 25.4% (16/63) didn't receive chemotherapy. A total of 22.2% (14/63) of patients received less than four cycles of chemotherapy, and 52.4% (33/63) received four or more cycles of chemotherapy. Among patients undergoing chemotherapy, 61.7% (29/47) received R-CHOP-like regimens, and 38.3% (18/47) used CHOP-like regimens. The 1-, 2-, 3-, and 5-year overall survival (OS) rates were 65.0% , 53.8% , 47.1% , and 43.5% , respectively. Univariate analysis revealed that age ≥ 60 years (P=0.012) , Eastern Cooperative Oncology Gruop Performance Status (ECOG-PS) score 2-4 points (P=0.043) , IPI score 3-5 points (P=0.001) , β(2)-MG elevation (≥5.5 mg/L) (P=0.007) , and systemic chemotherapy cycles less than four times (P<0.001) were the negative prognostic factors affecting the OS of patients. The Cox multivariate analysis depicted that age ≥60 years (HR=2.272, 95% CI 1.110-4.651, P=0.025) , IPI score 3-5 points (HR=3.562, 95% CI 1.794-7.074, P<0.001) , ECOG-PS score 2-4 points (HR=2.675, 95% CI 1.162-6.153, P=0.021) , and number of cycles of chemotherapy<4 (HR=0.290, 95% CI 0.176-0.479, P<0.001) were independent risk factors for adverse prognosis of OS. Conclusion: HIV-associated DLBCL is the most common HIV-related tumor, is most commonly seen in men, and has a high 1-year mortality rate. Chemotherapy combined with antiretroviral therapy can improve patient prognosis.

Evaluation of the clinical effect of an artificial intelligence-assisted diagnosis and treatment system for neonatal seizures in the real world: a multicenter clinical study protocol / 中国当代儿科杂志

Neonatal seizures are the most common clinical manifestations of critically ill neonates and often suggest serious diseases and complicated etiologies. The precise diagnosis of this disease can optimize the use of anti-seizure medication, reduce hospital costs, and improve the long-term neurodevelopmental outcomes. Currently, a few artificial intelligence-assisted diagnosis and treatment systems have been developed for neonatal seizures, but there is still a lack of high-level evidence for the diagnosis and treatment value in the real world. Based on an artificial intelligence-assisted diagnosis and treatment systems that has been developed for neonatal seizures, this study plans to recruit 370 neonates at a high risk of seizures from 6 neonatal intensive care units (NICUs) in China, in order to evaluate the effect of the system on the diagnosis, treatment, and prognosis of neonatal seizures in neonates with different gestational ages in the NICU. In this study, a diagnostic study protocol is used to evaluate the diagnostic value of the system, and a randomized parallel-controlled trial is designed to evaluate the effect of the system on the treatment and prognosis of neonates at a high risk of seizures. This multicenter prospective study will provide high-level evidence for the clinical application of artificial intelligence-assisted diagnosis and treatment systems for neonatal seizures in the real world.

Lipoprotein apheresis in patients with familial hypercholesterolemia: a single center research / 中华心血管病杂志

Objective: We evaluated the safety and efficacy of lipoprotein apheresis (LA) in patients with familial hypercholesterolemia (FH) who can't reach low-density lipoprotein cholesterol(LDL-C) target goals with the maximal tolerated dose of lipid-lowering agents. Methods: This was a retrospective cross-sectional study. Between February 2015 and November 2019, patients with FH who were admitted in Fuwai hospital and treated with LA were consecutively enrolled. Based on intensive lipid-lowering agents, these patients received LA by double filtration plasma pheresis (DFPP) method. The changes of lipid levels such as LDL-C and lipoprotein(a)[Lp(a)] were compared before and after LA treatment, and the changes of immunoglobulin (Ig) concentration and LA-related adverse effects were also discussed. Results: A total of 115 patients with FH were enrolled in this study, of which 8 cases were homozygous FH and 107 cases were heterozygous FH. The age was (43.9±12.2) years and there were 75 (65.2%) males, and 108 (93.8%) with coronary artery disease. For pre-and immediately after LA treatment, the LDL-C was (5.20±2.94) mmol/L vs. (1.83±1.08) mmol/L, Lp(a) concentration was 428.70(177.00, 829.50)mg/L vs. 148.90(75.90, 317.00) mg/L (P<0.001), with a decrease of 64.2% and 59.8% respectively. The levels of IgG and IgA measured 1 day after LA treatment were both in the normal range and IgM concentration was below the reference value, the reductions of which were 15.1%, 25.0% and 58.7% respectively (P<0.001). Six patients had mild symptoms of nausea, hypotension dyspnea and palpitation, the symptoms were relieved by symptomatic treatment. Conclusion: For patients with FH who do not achieve LDL-C target goal with the maximal tolerated lipid-lowering agents, especially those with elevated Lp(a) levels, LA, which can significantly further reduce LDL-C and Lp(a) levels, is an effective and safe option.

Mechanisms of Ersi Decoction on Rheumatoid Arthritis Rats Induced by Bovine Type Ⅱ Collagen-solution / 中国实验方剂学杂志

ObjectiveTo observe that effect of Ersi decoction on rats with rheumatoid arthritis （RA） induced by using the complete Freund's adjuvant emulsion containing bovine type Ⅱ collagenand and elucidate underlying menchanisms involving to inhibit inflammation and joint synovial angiogenesis. MethodThe rat model of RA was established by immune induction with complete Freund's adjuvant emulsion containing bovine type Ⅱ collagen. All male SD rats were randomly divided into blank group， RA model group， methotrexate group（1.0 mg·kg-1）， and low-， medium- and high-dose group（30，15，7.0 g·kg-1·d-1）of Ersi decoction， with 8 rats in each group. Except the blank group， rats in the methotrexate group and Ersi decoction groups were given corresponding doses of methotrexate and Ersi decoction after establishment of RA induced by strengthen immunity，respectively，and those in the model group and blank group received normal saline of equivalent volume，once a day for 28 days. After the administration， the degree of joint swelling of rats in each group was analyzed by joint swelling volume and index. The small animal ultrasound imaging system was used to detect the score and area of synovial hyperplasia of knee joint in right lower limb of rats and hematoxylin-eosin（HE）staining to observe the histomorphological changes in joint synovium of rats. The levels of tumor necrosis factor-α（TNF-α） and interleukin-1β（IL-1β） were measured by enzyme-linked immunosorbent assay（ELISA）. Immunohistochemistry was employed to analyze the expression of CD31 and vascular endothelial growth factor receptor 2（VEGFR2） in in joint synovium. ResultCompared with the blank group， the model group demonstrated significant increase in joint swelling volume and index， inflammatory cytokines including TNF-α and IL-1β in serum， the score and area of synovial hyperplasia of knee joint in right lower limb， obvious pathological changes in the synovium and the expression of CD31 and VEGFR2 in joint synovium. Medium and high-dose Ersi decoction significantly alleviated the pathological changes of synovium tissue， attenuated joint swelling volume and index and decreased the expression of CD31 and VEGFR2 in joint synovium as compared with the model group. Moreover， high-dose Ersi decoction showed significantly lower levels of TNF-α and IL-1β in serum， and the score and area of synovial hyperplasia of knee joint in right lower limb. But medium-dose Ersi decoction only showed lower levels of TNF-α and area of synovial hyperplasia of knee joint. ConclusionErsi decoction could reduce synovial inflammation and hyperplasia through inhibiting synovial angiogenesis in rats with RA induced by bovine type Ⅱ collagen for achieving the effect of reducing RA joint damage， which provides an important reference for anti-RA of Ersi decoction in clinical application.

Conclusions:Early infection after HT remains higher.It is significantly correlated with 24-48 h post-operation APACHE II score, ECMO post-operation, postoperative intrathoracic drainage tube indwelling time, postoperative gastric tube indwelling time, postoperative ventilator assisted treatment time and postoperative ICU time.Targeted interventions should be adopted for lowering the incidence of early infection after HT.

Research progress in the role of distal femoral valgus cut angle in accurate total knee arthroplasty / 中华创伤杂志

The distal femoral fracture, tibial plateau fracture and patellar fracture may all develop into traumatic knee arthritis, which is probably associated with knee dysfunction problems. Total knee arthroplasty (TKA) is an effective treatment for end-stage knee arthritis. The distal femoral valgus cut angle (VCA) is an important reference for distal femoral resection in TKA and significantly affects postoperative prosthesis position and lower extremity alignment after TKA. For VCA, the specific methods for definition, measurement methods, clinical application and influencing factors are currently controversial. Hence, the authors review the research progress in the role of VCA in TKA from the above-mentioned four aspects, hoping to provide a reference for accurate preoperative planning and intraoperative performance of TKA.

Application and research progress of intelligent accuracy technological aids in total knee arthroplasty / 中华创伤杂志

Total knee arthroplasty (TKA) is an effective treatment for end-stage knee disease, with the postoperative alignment, component position, soft tissue balance, and prosthesis matching being key factors for the success of TKA. In order to achieve more accurate postoperative alignment and component position, better soft tissue balance and prosthesis matching for longer prosthesis longevity, better postoperative function and higher patient satisfaction, various intelligent accuracy technological aids such as computer assisted navigation (CAN), patient specific instrumentation (PSI), surgical robots, microsensors, customized implants (CI) and personalized 3D preoperative planning have emerged and are given high expectation. In this paper, the authors review the application and research progress of the above technological aids mainly from aspects of alignment, component position, clinical outcomes and cost analysis, so as to provide a reference for the application of related technological aids in TKA.
