The impact of LDL-C/HDL-C ratio on severity of coronary artery disease and 2-year outcome in patients with premature coronary heart disease: results of a prospective, multicenter, observational cohort study / 中华心血管病杂志

Objective: To explore the relationship between low density lipoprotein cholesterol (LDL-C)/high density lipoprotein cholesterol (HDL-C) ratio with the severity of coronary artery disease and 2-yeat outcome in patients with premature coronary heart disease. Methods: This prospective, multicenter, observational cohort study is originated from the PROMISE study. Eighteen thousand seven hundred and one patients with coronary heart disease (CHD) were screened from January 2015 to May 2019. Three thousand eight hundred and sixty-one patients with premature CHD were enrolled in the current study. According to the median LDL-C/HDL-C ratio (2.4), the patients were divided into two groups: low LDL-C/HDL-C group (LDL-C/HDL-C≤2.4, n=1 867) and high LDL-C/HDL-C group (LDL-C/HDL-C>2.4, n=1 994). Baseline data and 2-year major adverse cardiovascular and cerebrovascular events (MACCE) were collected and analyzed in order to find the differences between premature CHD patients at different LDL-C/HDL-C levels, and explore the correlation between LDL-C/HDL-C ratio with the severity of coronary artery disease and MACCE. Results: The average age of the low LDL-C/HDL-C ratio group was (48.5±6.5) years, 1 154 patients were males (61.8%); the average age of high LDL-C/HDL-C ratio group was (46.5±6.8) years, 1 523 were males (76.4%). The number of target lesions, the number of coronary artery lesions, the preoperative SNYTAX score and the proportion of three-vessel coronary artery disease in the high LDL-C/HDL-C group were significantly higher than those in the low LDL-C/HDL-C group (1.04±0.74 vs. 0.97±0.80, P=0.002; 2.04±0.84 vs. 1.85±0.84, P<0.001; 13.81±8.87 vs. 11.70±8.05, P<0.001; 36.2% vs. 27.4%, respectively, P<0.001). Correlation analysis showed that there was a significant positive correlation between LDL-C/HDL-C ratio and preoperative SYNTAX score, the number of coronary artery lesions, the number of target lesions and whether it was a three-vessel coronary artery disease (all P<0.05). The 2-year follow-up results showed that the incidence of MACCE was significantly higher in the high LDL-C/HDL-C group than that in the low LDL-C/HDL-C group (6.9% vs. 9.1%, P=0.011). There was no significant difference in the incidence of all-cause death, cardiac death, myocardial infarction, stroke, revascularization and bleeding between the two groups. Cox multivariate regression analysis showed that the LDL-C/HDL-C ratio has no correlation with 2-year MACCE, death, myocardial infarction, revascularization, stroke and bleeding events above BARC2 in patients with premature CHD. Conclusion: High LDL-C/HDL-C ratio is positively correlated with the severity of coronary artery disease in patients with premature CHD. The incidence of MACCE of patients with high LDL-C/HDL-C ratio is significantly higher during 2 years follow-up; LDL-C/HDL-C ratio may be an indicator for evaluating the severity of coronary artery disease and long-term prognosis in patients with premature CHD.

Forsythiaside B inhibits cerebral ischemia/reperfusion-induced oxidative stress injury in mice via the AMPK/DAF-16/FOXO3 pathway / 南方医科大学学报

OBJECTIVE@#To study the protective effect of forsythiaside B (FB) against cerebral oxidative stress injury induced by cerebral ischemia/reperfusion (I/R) in mice and explore the underlying mechanism.@*METHODS@#Ninety C57BL/6 mice were randomized into sham-operated group, middle cerebral artery occlusion (MCAO) model group, and low-, medium and highdose (10, 20, and 40 mg/kg, respectively) FB groups. The expression levels of MDA, ROS, PCO, 8-OHdG, SOD, GSTα4, CAT and GPx in the brain tissue of the mice were detected using commercial kits, and those of AMPK, P-AMPK, DAF-16, FOXO3 and P-FOXO3 were detected with Western blotting. Compound C (CC), an AMPK inhibitor, was used to verify the role of the AMPK pathway in mediating the therapeutic effect of FB. In another 36 C57BL/6 mice randomized into 4 sham-operated group, MCAO model group, FB (40 mg/kg) treatment group, FB+CC (10 mg/kg) treatment group, TTC staining was used to examine the volume of cerebral infarcts, and the levels of ROS and SOD in the brain were detected; the changes in the protein expressions of AMPK, P-AMPK, DAF-16, FOXO3 and P-FOXO3 in the brain tissue were detected using Western blotting.@*RESULTS@#In mice with cerebral IR injury, treatment with FB significantly reduced the levels of ROS, MDA, PCO and 8-OHdG, increased the activities of antioxidant enzymes SOD, GSTα4, CAT and GPx, and enhanced phosphorylation of AMPK and FOXO3 and DAF-16 protein expression in the brain tissue (P < 0.01). Compared with FB treatment alone, the combined treatment with FB and CC significantly reduced phosphorylation of AMPK and FOXO3, lowered expression of DAF-16 and SOD activity, and increased cerebral infarction volume and ROS level in the brain tissue of the mice (P < 0.01).@*CONCLUSION@#FB inhibits oxidative stress injury caused by cerebral I/R in mice possibly by enhancing AMPK phosphorylation, promoting the downstream DAF-16 protein expression and FOXO3 phosphorylation, increasing the expression of antioxidant enzymes, and reducing ROS level in the brain tissue.

Genomics of next generation sequencing in pediatric B-acute lymphoblastic leukemia and its impact on minimal residual disease / 中华儿科杂志

Objective: To describe the gene mutation profile of newly diagnosed pediatric B-acute lymphoblastic leukemia (B-ALL) and analyze its effect on minimal residual disease (MRD). Methods: A total of 506 newly diagnosed B-ALL children treated in Institute of Hematology & Blood Diseases Hospital, Chinese Academy of Medical Sciences from September 2018 to July 2021 were enrolled in this retrospective cohort study. The enrolled children were divided into MRD ≥1.00% group and <1.00% group according to MRD results on the 19th day since chemotherapy, and MRD ≥0.01% group and <0.01% group according to MRD results on the 46th day. Clinical characteristics and gene mutations of two groups were compared. Comparisons between groups were performed with chi-square test or Fisher's exact test. Independent risk factors of MRD results on the 19th day and the 46th day were analyzed by Logistic regression model. Results: Among all 506 patients, there were 318 males and 188 females. On the 19th day, there were 114 patients in the MRD ≥1.00% group and 392 patients in the MRD <1.00% group. On the 46th day, there were 76 patients in the MRD ≥0.01% group and 430 patients in the MRD <0.01% group. A total of 187 gene mutations were detected in 487 (96.2%) of 506 children. The most common gene mutations were signal transduction-related KRAS gene mutations in 111 cases (22.8%) and NRAS gene mutations in 99 cases (20.3%). Multivariate analysis showed that PTPN11 (OR=1.92, 95%CI 1.00-3.63), KMT2A (OR=3.51, 95%CI 1.07-11.50) gene mutations and TEL-AML1 (OR=0.48, 95%CI 0.27-0.87), BCR-ABL1 (OR=0.27, 95%CI 0.08-0.92) fusion genes and age >10 years (OR=1.91, 95%CI 1.12-3.24) were independent influencing factors for MRD ≥1.00% on the 19th day. BCORL1 (OR=2.96, 95%CI 1.18-7.44), JAK2 (OR=2.99, 95%CI 1.07-8.42) and JAK3 (OR=4.83, 95%CI 1.50-15.60) gene mutations and TEL-AML1 (OR=0.43, 95%CI 0.21-0.87) fusion gene were independent influencing factors for MRD ≥0.01% on the 46th day. Conclusions: Children with B-ALL are prone to genetic mutations, with abnormalities in the RAS signaling pathway being the most common. Signal transduction related PTPN11, JAK2 and JAK3 gene mutations, epigenetic related KMT2A gene mutation and transcription factor related BCORL1 gene mutation are independent risk factors for MRD.

Analysis of 7 cases of pediatric acute myeloid leukemia with DEK-NUP214 fusion gene / 中华儿科杂志

Objective: To investigate the clinical features, treatment regime, and outcome of pediatric acute myeloid leukemia (AML) with DEK-NUP214 fusion gene. Methods: The clinical data, genetic and molecular results, treatment process and survival status of 7 cases of DEK-NUP214 fusion gene positive AML children admitted to the Pediatric Blood Diseases Center of Institute of Hematology & Blood Diseases Hospital, Chinese Academy of Medical Sciences from May 2015 to February 2022 were analyzed retrospectively. Results: DEK-NUP214 fusion gene positive AML accounted for 1.02% (7/683) of pediatric AML diagnosed in the same period, with 4 males and 3 females. The age of disease onset was 8.2 (7.5, 9.5) years. The blast percentage in bone marrow was 0.275 (0.225, 0.480), and 6 cases were M5 by FAB classification. Pathological hematopoiesis was observed in all cases except for one whose bone marrow morphology was unknown. Three cases carried FLT3-ITD mutations, 4 cases carried NRAS mutations, and 2 cases carried KRAS mutations. After diagnosis, 4 cases received IAE induction regimen (idarubicin, cytarabine and etoposide), 1 case received MAE induction regimen (mitoxantrone, cytarabine and etoposide), 1 case received DAH induction regimen (daunorubicin, cytarabine and homoharringtonine) and 1 case received DAE induction regimen (daunorubicin, cytarabine and etoposide). Complete remission was achieved in 3 cases after one course of induction. Four cases who did not achieved complete remission received CAG (aclarubicin, cytarabine and granulocyte colony-stimulating factor), IAH (idarubicin, cytarabine and homoharringtonine), CAG combined with cladribine, and HAG (homoharringtonine, cytarabine and granulocyte colony-stimulating factor) combined with cladribine reinduction therapy, respectively, all 4 cases reached complete remission. Six patients received hematopoietic stem cell transplantation (HSCT) after 1-2 sessions of intensive consolidation treatment, except that one case was lost to follow-up after complete remission. The time from diagnosis to HSCT was 143 (121, 174) days. Before HSCT, one case was positive for flow cytometry minimal residual disease and 3 cases were positive for DEK-NUP214 fusion gene. Three cases accepted haploid donors, 2 cases accepted unrelated cord blood donors, and 1 case accepted matched sibling donor. The follow-up time was 20.4 (12.9, 53.1) months, the overall survival and event free survival rates were all 100%. Conclusions: Pediatric AML with DEK-NUP214 fusion gene is a unique and rare subtype, often diagnosed in relatively older children. The disease is characterized with a low blast percentage in bone marrow, significant pathological hematopoiesis and a high mutation rate in FLT3-ITD and RAS genes. Low remission rate by chemotherapy only and very high recurrence rate indicate its high malignancy and poor prognosis. Early HSCT after the first complete remission can improve its prognosis.

Comparison of the effects and safety of dydrogesterone and medroxyprogesterone acetate on endometrial hyperplasia without atypia: a randomized controlled non-inferior phase Ⅲ clinical study / 中华妇产科杂志

Objective: To compare the effects and safety of dydrogesterone (DG) and medroxyprogesterone acetate (MPA) on the treatment in patients with endometrial hyperplasia without atypia (EH). Methods: This was a single-center, open-label, prospective non-inferior randomized controlled phase Ⅲ trial. From February 2019 to November 2021, patients with EH admitted to the Obstetrics and Gynecology Hospital of Fudan University were recruited. Enrolled patients were stratified according to the pathological types of simple hyperplasia (SH) or complex hyperplasia (CH), and were randomised to receive MPA or DG. Untill May 14, 2022, the median follow-up time after complete response (CR) was 9.3 months (1.1-17.2 months). The primary endpoint was the 6-month CR rate (6m-CR rate). The secondary endpoints included the 3-month CR rate (3m-CR rate), adverse events rate, recurrence rate, and pregnancy rate in one year after CR. Results: (1) A total of 292 patients with EH were enrolled in the study with the median age of 39 years (31-45 years). A total of 135 SH patients were randomly assigned to MPA group (n=67) and DG group (n=68), and 157 CH patients were randomly assigned to MPA group (n=79) and DG group (n=78). (2) Among 292 patients, 205 patients enrolled into the primary endpoint analysis, including 92 SH patients and 113 CH patients, with 100 patients in MPA group and 105 in DG group, respectively. The 6m-CR rate of MPA group and DG group were 90.0% (90/100) and 88.6% (93/105) respectively, and there were no statistical significance (χ2=0.11, P=0.741), with the rate difference (RD) was -1.4% (95%CI:-9.9%-7.0%). Stratified by the pathology types, the 6m-CR rate of SH patients was 93.5% (86/92), and MPA group and DG group were respectively 91.1% (41/45) and 95.7% (45/47); and the 6m-CR rate of CH patients was 85.8% (97/113), and MPA group and DG group were 89.1% (49/55) and 82.8% (48/58) respectively. The 6m-CR rates of the two treatments had no statistical significance either (all P>0.05). A total of 194 EH patients enrolled into the secondary endpoint analysis, including 88 SH patients and 106 CH patients, and 96 patients in MPA group and 98 in DG group, respectively. The 3m-CR rate of SH patients were 87.5% (77/88), while the 3m-CR rates of MPA group and DG group were 90.7% (39/43) and 84.4% (38/45), respectively; the 3m-CR rate of CH patients was 66.0% (70/106), and MPA group and DG group had the same 3m-CR rate of 66.0% (35/53). No statistical significance was found between the two treatments both in SH and CH patients (all P>0.05). (3) The incidence of adverse events between MPA group and DG group had no statistical significance (P>0.05). (4) A total of 93 SH patients achieved CR, and the cumulative recurrence rate in one year after CR were 5.9% and 0 in MPA group and DG group, respectively. While 112 CH patients achieved CR, and the cumulative recurrence rate in one year after CR were 8.8% and 6.5% in MPA group and DG group, respectively. There were no statistical significance between two treatment groups (all P>0.05). Among the 93 SH patients, 10 patients had family planning but no pregnancy happened during the follow-up period. Among the 112 CH patients, 21 were actively preparing for pregnancy, and the pregnancy rate and live-birth rate in one year after CR in MPA group were 7/9 and 2/7, while in DG group were respectively 4/12 and 2/4, and there were no statistical significance in pregnancy rate and live-birth rate between the two treatment groups (all P>0.05). Conclusions: Compared with MPA, DG is of good efficacy and safety in treating EH. DG is a favorable alternative treatment for EH patients.

Advances in the study of new BCR-ABL kinase inhibitors / 药学学报

The oncogenic product of BCR-ABL is an abnormal tyrosine kinase that causes chronic myeloid leukemia (CML). With further research into the pathogenesis of CML, the discovery of compounds that selectively inhibit abnormal BCR-ABL tyrosine kinases is a research focus worthy of attention. The first three generations of BCR-ABL inhibitors are orthosteric inhibitors, which competitively block the binding of ABL protein tyrosine kinase to ATP and prevent it from activating downstream signals. The fourth-generation BCR-ABL inhibitors allosterically inhibit ABL protein tyrosine kinase by binding to the myristoyl pocket, providing greater selectivity and maintaining activity against drug-resistant mutations proteins. Novel drug design strategies such as proteolytic targeting chimera (PROTAC), covalent inhibitors and dual targeting inhibitors also provide new directions for the development of BCR-ABL kinase inhibitors. This paper reviews recent research advances on BCR-ABL kinase inhibitors and discusses drug design strategies for various novel BCR-ABL inhibitors.

Safety and short-term effectiveness of blinatumomab in the treatment of childhood relapsed/refractory acute lymphoblastic leukemia / 中国当代儿科杂志

OBJECTIVES@#To study the safety and short-term effectiveness of blinatumomab in the treatment of childhood relapsed/refractory acute lymphoblastic leukemia (R/R-ALL).@*METHODS@#Six children with R/R-ALL who received blinatumomab treatment from August 2021 to August 2022 were included as subjects, and a retrospective analysis was performed for their clinical data.@*RESULTS@#Among the six children, there were three boys and three girls, with a median age of 10.5 (5.0-13.0) years at the time of inclusion. Of all six children, one had refractory ALL and did not achieve remission after several times of chemotherapy, and 5 relapsed for the first time, with a median time of 30 (9-60) months from diagnosis to relapse. Minimal residual disease (MRD) before treatment was 15.50% (0.08%-78.30%). Three children achieved complete remission after treatment, among whom two had negative conversion of MRD. Five children had cytokine release syndrome (CRS), among whom 3 had grade 1 CRS and 2 had grade 2 CRS. Four children were bridged to allogeneic hematopoietic stem cell transplantation, with a median interval of 50 (40-70) days from blinatumomab treatment to transplantation. The six children were followed up for a median time of 170 days, and the results showed an overall survival rate of 41.7% (95%CI: 5.6%-76.7%) and a median survival time of 126 (95%CI: 53-199) days.@*CONCLUSIONS@#Blinatumomab has good short-term safety and effectiveness in the treatment of childhood R/R-ALL, and its long-term effectiveness needs to be confirmed by studies with a larger sample size.

Clinical features and prognosis of juvenile myelomonocytic leukemia: an analysis of 63 cases / 中国当代儿科杂志

OBJECTIVES@#To investigate the clinical features of juvenile myelomonocytic leukemia (JMML) and their association with prognosis.@*METHODS@#Clinical and prognosis data were collected from the children with JMML who were admitted from January 2008 to December 2016, and the influencing factors for prognosis were analyzed.@*RESULTS@#A total of 63 children with JMML were included, with a median age of onset of 25 months and a male/female ratio of 3.2∶1. JMML genetic testing was performed for 54 children, and PTPN11 mutation was the most common mutation and was observed in 23 children (43%), among whom 19 had PTPN11 mutation alone and 4 had compound PTPN11 mutation, followed by NRAS mutation observed in 14 children (26%), among whom 12 had NRAS mutation alone and 2 had compound NRAS mutation. The 5-year overall survival (OS) rate was only 22%±10% in these children with JMML. Of the 63 children, 13 (21%) underwent hematopoietic stem cell transplantation (HSCT). The HSCT group had a significantly higher 5-year OS rate than the non-HSCT group (46%±14% vs 29%±7%, P<0.05). There was no significant difference in the 5-year OS rate between the children without PTPN11 gene mutation and those with PTPN11 gene mutation (30%±14% vs 27%±10%, P>0.05). The Cox proportional-hazards regression model analysis showed that platelet count <40×109/L at diagnosis was an influencing factor for 5-year OS rate in children with JMML (P<0.05).@*CONCLUSIONS@#The PTPN11 gene was the most common mutant gene in JMML. Platelet count at diagnosis is associated with the prognosis in children with JMML. HSCT can improve the prognosis of children with JMML.

Research progress on the cardiorenal protection of non-steroid mineralocorticoid receptor antagonists in patients with chronic kidney disease / 生理学报

Mineralocorticoid receptor antagonists not only are used as a diuretics to treat essential hypertension, but also protect the heart and kidney by inhibiting inflammation and fibrosis. Since the discovery of spironolactone, the first generation of mineralocorticoid receptor antagonist, two types of non-steroid mineralocorticoid receptor antagonists (finerenone and esaxerenone) approved for clinical use have been developed, which have the advantages of high affinity, high selectivity and balanced distribution in heart and kidney, and can be used in clinic as a cardiorenal protective drug. In this paper, the development history of mineralocorticoid receptor antagonists was reviewed, and the pathophysiological mechanism of inflammation and fibrosis caused by mineralocorticoid receptors and the similarities and differences of different generations of mineralocorticoid receptor antagonists were analyzed. In particular, the phase III clinical research evidence of finerenone and esaxerenone was discussed. This paper also reviews the research progress of cardiorenal protection of non-steroid mineralocorticoid receptor antagonists in patients with chronic kidney disease.

Effect of fudosteine on lung cancer cells in an inflammatory microenvironment based on metabolomics / 药学学报

GC-MS metabolomics was used to investigate the effects of fudosteine on lung cancer A549 cells in an inflammatory microenvironment. Eleven metabolites (malic acid, isoleucine, lactose, galactinol, creatinine, gluconic acid, oleic acid, phosphate, S-carboxymethyl-L-cysteine, uridine and tagatose) were identified in the metabolomics results and could be used as biomarkers of fudosteine treatment. Pathway enrichment analysis showed that the metabolic pathways of amino acids including isoleucine, valine, leucine, glycine, serine and threonine were significantly altered, as were the metabolic pathways of carbohydrates such as galactose and pentose phosphate. Fudosteine significantly reduced the level of inflammatory factors in A549 cells and corrected the inflammatory microenvironment by interfering with the effects of amino acid metabolites and amino acid metabolism pathways. This study reveals that fudosteine may be able to inhibit the continuous inflammatory response and prevent the further progression of lung cancer by suppressing the inflammatory microenvironment.

Identification of Escherichia coli β-glucuronidase inhibitors from Polygonum cuspidatum Siebold & Zucc

Abstract Gut bacterial β-glucuronidase (GUS) can reactivate xenobiotics that exert enterohepatic circulation- triggered gastrointestinal tract toxicity. GUS inhibitors can alleviate drug-induced enteropathy and improve treatment outcomes. We evaluated the inhibitory effect of Polygonum cuspidatum Siebold & Zucc. and its major constituents against Escherichia coli GUS (EcGUS), and characterized the inhibitory mechanism of each of the components. Trans-resveratrol 4'-O-β-D-glucopyranoside (HZ-1) and (-)-epicatechin gallate (HZ-2) isolated from P. cuspidatum were identified as the key components and potent inhibitors. These two components displayed strong to moderate inhibitory effects on EcGUS, with Ki values of 9.95 and 1.95 μM, respectively. Results from molecular docking indicated that HZ-1 and HZ-2 could interact with the key residues Asp163, Ser360, Ile 363, Glu413, Glu504, and Lys 568 of EcGUS via hydrogen bonding. Our findings demonstrate the inhibitory effect of P. cuspidatum and its two components on EcGUS, which supported the further evaluation and development of P. cuspidatum and its two active components as novel candidates for alleviating drug-induced damage in the mammalian gut.

Research Progress on Anti-tumor Effect and Mechanism of Cucurbitacins / 中国实验方剂学杂志

Cancer is a major global public health problem. Statistics from the national cancer center of China also show that cancer has become a major disease threatening human health with increasing morbidity and mortality. The occurrence and development mechanism of cancer is complex， involving multiple stages， multiple genes and multiple signaling pathways. Conventional chemoradiotherapy and emerging targeted therapy methods are the main methods in treatment of tumor. However， the quality of life of patients as well as the sustained and effective therapeutic effect are seriously affected due to the toxic side effects and drug resistance. Therefore， it is the global focus to find safe and effective anti-cancer drugs. The research and development and application of anti-cancer herbal medicines such as paclitaxel， vinblastine， podophyllin， ginsenoside and ginseng polysaccharide have brought new hope for the treatment of cancer. Cucurbitacine from Chinese medicine cucurbitaceae plantsare is a kind of highly oxidized tetracyclic triterpene compound with extensive pharmacological effects and complex mechanism. In the family of cucurbitacines， cucurbitin B， D， E and I have been studied most frequently on anticancer effect， and in a large number of studies， they have been found to play an important role in tumor diseases of the digestive system， respiratory system， reproductive system， blood system， urinary system and so on. With significant effect in inhibiting tumor cells proliferation， blocking the cell cycle， inducing apoptosis and autophagy death， inhibiting cell migration and invasion， inhibiting tumor angiogenesis， regulating the levels of reactive oxygen species and regulating immune system， such cucurbitacins are expected to be developed as a new kind of anti-cancer drugs. The authors of this study aim to provide reference for the further research and development of new anti-cancer drugs about cucurbitines by summarizing the anti-tumor effect and mechanism of the cucurbitacins.

Chinese Medicine Injections in Treatment of Esophageal Cancer： A Review / 中国实验方剂学杂志

Esophageal cancer has a high morbidity and mortality worldwide， and the burden of esophageal cancer is still heavy in China. The conventional treatments such as radiotherapy and chemotherapy fail to yield a satisfactory outcome， implying that the safe and effective treatments are not available for the majority of patients. At present， esophageal cancer is mainly treated by Chinese medicine combined with radiotherapy and chemotherapy. The retrieval of related papers in Chinese and English reveals that Kang'ai injection， Compound Kushen injection， Kanglaite injection， Xiaoaiping injection， Aidi injection， Bruceae Fructus Oil Emulsion， Cinobufotalin injection， and Shenmai injection have been commonly used in esophageal cancer treatment. These eight injections are either single medicinal or compound preparations， involving 11 Chinese medicinals， which synergize the effects of radiotherapy and chemotherapy and reduce their adverse reactions in the treatment of esophageal cancer. Due to the complexity of Chinese medicinal components， a series of adverse reactions such as phlebitis， phlebosclerosis， and hemolysis may be caused by irrational dosage， administration speed， and compatibility in the use of injection. There are many clinical studies on Chinese medicine injections for anti-esophageal cancer but few studies on their active components and molecular mechanism. This paper reviewed the active components， effectiveness， safety， and mechanism of Chinese medicine injections frequently employed for treating esophageal cancer， in order to provide reference for their clinical application as well as the development of new Chinese drugs.

Expert Consensus on Otorhinolaryngology Head and Neck Diseases Responding Specifically to Traditional Chinese Medicine / 中国实验方剂学杂志

Traditional Chinese medicine （TCM） and western medicine have their respective advantages and limitations in the diagnosis and treatment of common otorhinolaryngology head and neck diseases. Although the integrated TCM and western medicine exhibits definite curative effects， there is no consensus on the otorhinolaryngology head and neck diseases responding specifically to TCM or integrated TCM and western medicine， as well as the diagnosis and treatment schemes. The China Association of Chinese Medicine （CACM） thus organized the otorhinolaryngology head and neck specialists of both TCM and western medicine to discuss the etiology， pathogenesis， and clinical diagnosis and treatment methods of common otorhinolaryngology head and neck diseases with the results of multiple clinical trials taken into account. The acute pharyngitis， chronic pharyngolaryngitis， paraesthesia pharyngis， hysterical aphasia， allergic rhinitis， subjective tinnitus， and otogenic vertigo were confirmed to respond specifically to TCM or integrated TCM and western medicine. Then a mutually agreed diagnosis and treatment scheme and recommendation with integrated TCM and western medicine was formulated as a reference for clinical practice， thus benefiting more patients.

Effects of Wuqinxi on Balance, Walking and Quality of Life for Patients with Parkinson's Disease / 中国康复理论与实践

Objective:To observe the effects of traditional Chinese exercise Wuqinxi on balance, walking and quality of life for patients with Parkinson's disease. Methods:From December, 2018 to December, 2020, 62 inpatients with Parkinson's disease in the Affiliated Hospital of Shandong University of Chinese Medicine were randomly divided into control group (n = 31) and observation group (n = 31). The control group received routine medicine and rehabilitation training, while the observation group received Wuqinxi in addition, for eight weeks. The trajectory length and ellipse area of the center of pressure in 30 seconds were measured with PRO-KIN before and after treatment, while they were assessed with Berg Balance Scale (BBS), Timed 'Up and Go' Test (TUGT) and Parkinson's Disease Quality of Life Scale-39 (PDQ-39). Results:The trajectory length and ellipse area of the center of pressure, BBS score, TUGT time, and PDQ-39 score improved in both groups after treatment (t > 11.225, P < 0.001), and all improved more in the observation group than in the control group (t > 5.919, P < 0.001).

OBJECTIVE@#To investigate the clinical efficacy of high dose methotrexate (HD-MTX), temozolomide (TMZ), and rituximab (R) in the treatment of patients with primary central nervous system lymphoma (PCNSL).@*METHODS@#Clinical data of patients with PCNSL diagnosed and treated in Guangdong Provincial People's Hospital from February 2010 to May 2017 were collected. First, patients were given 6-8 cycles of MTX (3.5 g/m@*RESULTS@#There were 42 patients enrolled in the study, 17 cases in HD-MTX+TMZ group and 25 cases in HD-MTX+TMZ+R group. The median PFS and OS times in HD-MTX+TMZ+R group were 56.7 months and N/A, respectively, while, 7.3 months and 34.7 months in HD-MTX+TMZ group, respectively. In addition, there was no significant difference in median survival between patients who received TMZ maintenance therapy and those who were only actively monitored. During the induction period, all the patients had grade 1-2 nausea and vomiting, while in the consolidation treatment period, no grade 3/4 toxicity was observed.@*CONCLUSION@#The combination of HD-MTX+TMZ+R in the treatment of PCNSL patients shows a definite short-term effect, which can increase the survival rate of the patients. The side effects are mild, and the patients can generally tolerate.

Advances of Akkermansia muciniphila in regulating host functions / 中国中药杂志

Akkermansia muciniphila, abbreviated as AKK and found in 2004, is an oval-shaped gram-negative bacterium isolated from a human feal. A. muciniphila is widely present in the intestinal tract of human. Its specialization in mucin degradation makes it a key organism at the mucosal interface between the lumen and host cells. More and more studies have shown that it can play the role of probiotics. Notably, declined levels of A. muciniphila have been observed in patients with diabetes, liver disease, cardiovascular disease, inflammatory bowel disease, neurodegenerative diseases, etc. In addition, A. muciniphila combined with traditional Chinese medicine, exhibited higher effect on regulating host functions, but the underlying mechanism was still unclear, requiring further in-depth research. Therefore, the aims of this review are to summarize the main effects of A. muciniphila on host health and its relationship with traditional Chinese medicine, summarize the main problems, and provide a reference for the further research of A. muciniphila and traditional Chinese medicine.

Clinical features related to lymphatic metastasis in grade 3 endometroid endometrial cancer: a retrospective cross-sectional study / 中华医学杂志(英文版)

BACKGROUND@#Endometrial cancer (EC) has been one of the most general cancers with respect to gynecological malignancies; however, there are debates on clinical strategies concerning treatments especially for patients with grade 3 (G3) endometroid endometrial cancer (EEC). Present study aimed to evaluate the lymphatic metastasis (LM) related factors and figure out the necessity of lymphadenectomy for G3 EEC patients.@*METHODS@#From January 2009 to April 2019, 3751 EC patients were admitted to Obstetrics and Gynecology Hospital of Fudan University. Clinical characteristics include age, grade, stage, and clinical pathological features. A total of 1235 EEC patients were involved in the multivariable analysis. Three hundred and eighty-one patients were involved in the survival analysis and the data attributed to sufficient follow-up information. Kaplan-Meier curve and log-rank test were utilized to analyze the survival rate.@*RESULTS@#Among the 1235 EEC patients, 181 (14.7%) were categorized as G3 and 1054 (85.3%) were grade 1 to grade 2 (G1-2). Multivariate analysis demonstrated that lymphovascular space invasion, adnexal involvement, and cervical stroma involvement were independent risk factors of LM in G3 cohort with odds ratio 3.4, 5.8, and 8.9; 95% confidence interval 1.1-10.6, 1.5-22.4, and 2.8-28.0, respectively. LM rates increased from 3.3% (3/92) to 75% (9/12) for G3 EEC cohort as related factor numbers increased from one to three. There were no differences between G3 and G1-2 EEC in overall survival and progression free survival. Additionally, no survival advantage was observed for G3 EEC patients at early stage with different plans of adjuvant treatment.@*CONCLUSIONS@#For G3 EEC patients without other pathological positive factor, the LM rate is lower than those with other pathological positive factor. Survival analysis showed no difference between G3 cohort and G1-2 cohort. Also, different adjuvant treatments had no impact on the overall survival for G3 EEC patients.

Ophiopogonin D interferes with ferroptosis to reduce the damage of cardiomyocytes induced by ophiopogonin D' / 药学学报

This study investigated the intervention effect and possible mechanism of ophiopogonin D (OPD) in protecting cardiomyocytes against ophiopogonin D' (OPD')-induced injury, and provided relevant experimental data for the clinical use of Ophiopogon japonicas. Cell counting kit-8 (CCK-8) assay was used to evaluate the effect of OPD and OPD' on H9c2 cell viability. The content of reaction oxygen species (ROS) in cells were detected by flow cytometry. The contents of Fe2+ in cells were detected by FerroOrange's fluorescence imaging. The content of glutathione (GSH) and glutathione peroxidase (GSH-Px) were detected by kits. The expression of transferrin receptor 1 (TFR1), cyclooxygenase 2 (COX2), NADPH oxidase 1 (NOX1), long-chain acyl-CoA synthetase 4 (ACSL4), cationic amino acid transporter 11 (SLC7A11), glutathione peroxidase 4 (GPX4), and ferritin heavy chain 1 (FTH1) was detected by Western blot. Results showed that OPD' (1 μmol·L-1) significantly induced the expression of ferroptosis-related proteins, the contents of Fe2+, ROS, and GSH-Px were increased, and the content of GSH were decreased. In addition, different concentrations of OPD (0.5, 1, and 2 μmol·L-1) could partially reverse the myocardial cell injury caused by OPD', and the best effect was obtained when the dose range was 1-2 μmol·L-1. The experimental results show that OPD can interfere with the ferroptosis caused by OPD', and then have a protective effect on H9c2 cells.
