Efficacy and Survival of Venetoclax Based Regimen in the Treatment of Acute Myeloid Leukemia / 中国实验血液学杂志

OBJECTIVE@#To explore the efficacy and survival of venetoclax based (VEN-based) regimen in the treatment of acute myeloid leukemia（AML）.@*METHODS@#A retrospective study was conducted in patients who received VEN-based regimen and completed at least 1 course of efficacy evaluation at the The First Affiliated Hospital of Nanchang University from July 2019 to July 2022. The incidence of complete remission （CR）/CR with incomplete hematologic recovery （CRi） rate, objective remission rate（ORR） and survival of patients with different risk strati- fication and gene subtypes were analyzed.@*RESULTS@#A total of 79 patients were enrolled, including 43 patients with newly diagnosed unfit AML （unfit AML） and 36 relapsed/refractory AML (R/R AML). The median age of the patients was 62(14-83) years old. 36 out of 79 patients achieved CR/CRi and the ORR of the whole cohort was 64.6%. The CR/CRi rate of unfit AML patients was significantly higher than that of R/R AML patients (60.5% vs 27.8%, P=0.004). In unfit AML cohort, the patients with NPM1 and IDH1/2 mutations were benefited, 8 out of 9 patients ahcieved CR/CRi, 7/8 and 5/8 patients achieved minimal residual disease (MRD) negativity, respectively. Six out of 9 patients with TET2 mutation achieved CR/CRi, 3/6 patients achieved MRD negativity. In R/R AML cohort, 2 out of 3 patients with RUNX1 mutation achieved CR/CRi, without MRD negative, while the CR/CRi rate of patients with other gene mutations was lower than 40%. The median follow-up time was 10.1(95%CI: 8.6-11.6) months. In whole cohort, the median overall survival (mOS) time was 9.1 months and the relapse free survival (RFS) time was not reached. The mOS and RFS of unfit AML patients were significantly longer than those of R/R AML patients (14.1 vs 6.8 months, P=0.013; not reached vs 3.3 months, P=0.000). In unfit AML cohort, the mOS of patients with NPM1 or IDH1/2 mutations was not reached, while that of patients without NPM1 or IDH1/2 mutations was 8.0 months (P=0.009; P=0.022). Furthermore, the mOS of patients with TP53 mutaion was significantly shorter than that of patients without TP53 mutation (5.2 vs 14.1 months， P=0.049). In R/R AML cohort, there was no significant difference in mOS between patients with mutation in each gene subtype and those without gene mutation (P>0.05). All patients had hematology adverse reactions, 91.1% patients had AE grade≥3. The most common non-hematology adverse reactions was infection, with an incidence of 91.1%. VEN-based regimen was tolerable for AML patients.@*CONCLUSION@#VEN-based regimen can achieve a high response rate, especially in unfit AML with acceptable safety, and some patients can achieve MRD negative. It is also effective in NPM1-, IDH1/2-positive patients with long survival time.

Efficacy and Safety of Flumatinib in Treatment of Patients with Chronic Myeloid Leukemia / 中国实验血液学杂志

OBJECTIVE@#To analyze the efficacy and safety of flumatinib in the treatment of patients with chronic myeloid leukemia (CML).@*METHODS@#The clinical data of 56 CML patients treated with flumatinib from January 2020 to December 2021 in the First Affiliated Hospital of Nanchang University were retrospectively analyzed. Patients were divided into three groups: 35 new diagnosed CML patients treated with flumatinib (group A), 10 patients with imatinib/dasatinib intolerance (group B) and 11 patients with imatinib/dasatinib resistance (group C) switched to flumatinib treatment, respectively. The molecular response and adverse effects of flumatinib treatment were evaluated.@*RESULTS@#In group A, the early molecular response (EMR) at 3 months was 40.0%, and the major molecular response (MMR) at 6 and 12 months was 43.7% and 46.2%, respectively. In group B, the EMR was 50.0% at 3 months, and the MMR was 70.0% and 66.2% at 6 and 12 months, respectively. Among evaluable patients, 6 cases in group B achieved molecular response of 4.5 (MR4.5) at 12 months after switching to flumatinib treatment. In group C, 3 cases who switched from imatinib resistance to flumatinib achieved MR4.5 at 12 months, but 2 cases who switched from dasatinib resistance to flumatinib failed. Subgroup analysis showed significant differences in EUTOS long-term survival (ELTS) scores for patients in the medium-risk/high-risk group compared with those in the low-risk group for 3-month EMR (18.8% vs 57.9%), 6-month MMR (15.4% vs 63.2%) and 12-month MR4.5 (15.4% vs 69.2%) (P =0.036, P =0.012,P =0.015). The most common adverse effect in group A was thrombocytopenia, accounting for 54.5%, and 22.8% (8/35) patients discontinued the drug due to haematological adverse effects. Compared with patients who did not discontinue the drug or whose recovery time from discontinuation due to haematological toxicity was <1 month, patients whose recovery time from discontinuation was ≥1 month had a significantly worse 3-month EMR, 6-month MMR and 12-month MR4.5 (P =0.028, P =0.021, P =0.002).@*CONCLUSIONS@#Flumatinib has better molecular response and tolerance in patients with primary, imatinib/dasatinib-intolerant or resistant CML. Medium-risk/high-risk in ELTS score and time to recovery from discontinuation due to haematological toxicity ≥1 month are important factors influencing achievement of better molecular response in flumatinib treatment.

Clinical analysis of liver dysfunction induced by SHR-1210 alone or combined with apatinib and chemotherapy in patients with advanced esophageal squamous cell carcinoma / 中华肿瘤杂志

Objective: To investigate the clinical characteristics of abnormal liver function in patients with advanced esophageal squamous carcinoma treated with programmed death-1 (PD-1) antibody SHR-1210 alone or in combination with apatinib and chemotherapy. Methods: Clinical data of 73 patients with esophageal squamous carcinoma from 2 prospective clinical studies conducted at the Cancer Hospital Chinese Academy of Medical Sciences from May 11, 2016, to November 19, 2019, were analyzed, and logistic regression analysis was used for the analysis of influencing factors. Results: Of the 73 patients, 35 had abnormal liver function. 13 of the 43 patients treated with PD-1 antibody monotherapy (PD-1 monotherapy group) had abnormal liver function, and the median time to first abnormal liver function was 55 days. Of the 30 patients treated with PD-1 antibody in combination with apatinib and chemotherapy (PD-1 combination group), 22 had abnormal liver function, and the median time to first abnormal liver function was 41 days. Of the 35 patients with abnormal liver function, 2 had clinical symptoms, including malaise and loss of appetite, and 1 had jaundice. 28 of the 35 patients with abnormal liver function returned to normal and 7 improved to grade 1, and none of the patients had serious life-threatening or fatal liver function abnormalities. Combination therapy was a risk factor for patients to develop abnormal liver function (P=0.007). Conclusions: Most of the liver function abnormalities that occur during treatment with PD-1 antibody SHR-1210 alone or in combination with apatinib and chemotherapy are mild, and liver function can return to normal or improve with symptomatic treatment. For patients who receive PD-1 antibody in combination with targeted therapy and chemotherapy and have a history of long-term previous smoking, alcohol consumption and hepatitis B virus infection, liver function should be monitored and actively managed in a timely manner.

Combination of anlotinib and irinotecan in the second-line treatment of metastatic colorectal cancer: a multicenter phase 1/2 trial / 中华肿瘤杂志

Objective: To evaluate the safety and efficacy of anlotinib plus irinotecan in the second-line treatment of patients with metastatic colorectal cancer (mCRC). Methods: This prospective phase 1/2 study was conducted in 2 centers in China (Cancer Hospital of Chinese Academy of Medical Sciences and Jiangsu Province Hospital). We enrolled patients with mCRC whose disease had progressed after first-line systemic therapy and had not previously treated with irinotecan to receive anlotinib plus irinotecan. In the phase 1 of the trial, patients received anlotinib (8 mg, 10 mg or 12 mg, po, 2 weeks on/1 week off) in combination with fixed-dose irinotecan (180 mg/m(2), iv, q2w) to define the maximum tolerated dose (MTD) and recommended phase 2 dose (RP2D). In the phase 2, patients were treated with the RP2D of anlotinib and irinotecan. The primary endpoints were MTD and objective response rate (ORR). Results: From May 2018 to January 2020, a total of 31 patients with mCRC were enrolled. Anlotinib was well tolerated in combination with irinotecan with no MTD identified in the phase 1, and the RP2D was 12 mg. Thirty patients were evaluable for efficacy analysis. Eight patients achieved partial response, and 21 had stable disease, 1 had progressive disease. The ORR was 25.8% and the disease control rate was 93.5%. With a median follow-up duration of 29.5 months, the median progression-free survival and overall survival were 6.9 months (95% CI: 3.7, 9.3) and 17.6 months (95% CI: 12.4, not evaluated), respectively. The most common grade 3 treatment-related adverse events (≥10%) were neutropenia (25.8%) and diarrhea (16.1%). There was no treatment-related death. Conclusion: The combination of anlotinib and irinotecan has promising anti-tumor activity in the second-line treatment of mCRC with a manageable safety profile.

Mediating role of family function between coping strategies and emotional behavior in children with chronic superficial gastritis / 四川精神卫生

BackgroundChronic superficial gastritis （CSG） is a common clinical disease in children. The emotional behavior of CSG children is susceptible due to them suffering from such disease at young age. ObjectiveTo explore the impact of coping strategies on emotional behavior and the effect of family function in children with CSG， and to provide references for clinical intervention in CSG children with emotional behavior problems. MethodsA total of 177 children with CSG admitted to Anhui Children's Hospital from June 2019 to January 2023 were selected as the research subjects. Investigation on family function， emotional and behavioral problems and coping strategies of children was conducted by employing the Family APGAR index （APGAR）， the Strengths and Difficulties Questionnaire （SDQ） and Coping Strategies Questionnaire （CSQ）. The structural equation model was used to test the mediating effect of family function between coping strategies and emotional behaviors. ResultsThe APGAR score was negatively correlated with both SDQ score and negative coping strategies score （r=-0.507， -0.551， P<0.01）， but was positively correlated with positive coping strategy score （r=0.579， P<0.01）. The positive coping strategy score was negatively correlated with SDQ score （r=-0.539， P<0.01）， while the negative coping strategy score was positively correlated with SDQ score （r=0.543， P<0.01）. The result showed that family function played a partial mediating role between positive coping strategies and emotional behavior ［indirect effect was -0.133 （95% CI： -0.256~-0.079， P<0.01）， accounting for 29.40% of the total effect］. The same mediating effect happened between negative coping strategies and emotional behavior ［indirect effect was 0.093 （95% CI： 0.198~0.045， P<0.01）， accounting for 28.50% of the total effect］. ConclusionCoping strategies of CSG children can affect emotional behavior directly and indirectly with family function playing a partial intermediary effect.

Preliminary study of familial nonsyndromic tooth agenesis caused by ectodysplasin A mutation / 口腔疾病防治

Objective@# To explore the pathogenic genes in a Chinese family affected by nonsyndromic tooth agenesis so as to study the pathogenesis of oligodontia.@*Methods @# Hospital ethical approval and informed consent of the patients and family members were obtained. Clinical data of the proband and close family members were collected, peripheral venous blood was collected, and DNA was extracted. Gene sequencing was performed through whole-exome sequencing, and then the screened pathogenic genes were verified by Sanger sequencing. The three-dimensional structure of the mutant proteins was analyzed and compared with the wild-type using bioinformatics tools.@*Results@#The two patients with congenital majority tooth loss in this family were cousins, and there were no other patients with congenital majority tooth loss in the family. Besides congenital multiple tooth loss, the two patients had no obvious hair abnormalities, finger/toe abnormalities, sweating abnormalities or other abnormal manifestations of ectodermal tissue. We found a mutant gene that in this family by carrying out gene sequencing of the patients and their close family members. A novel EDA (ectodysplasin A) missense mutation c.983C>T (p. Pro328Leu) was identified, which changed the encoded amino acid from proline (Pro) to leucine (Leu). Analysis of the mutation site showed that the site was highly conserved, and three-dimensional structure modeling also found that it changed the structure of EDA. @* Conclusion@#A novel EDA missense variant (c.983C>T, p.Pro328Leu) was first identified in a Chinese family with nonsyndromic tooth agenesis, extending the mutation spectrum of the EDA gene.

Thoracoscopic laparoscopy-assisted Ivor-Lewis resection of esophagogastric junction cancer / 中华肿瘤杂志

Objective: To investigate the outcome of patients with esophagogastric junction cancer undergoing thoracoscopic laparoscopy-assisted Ivor-Lewis resection. Methods: Eighty-four patients who were diagnosed with esophagogastric junction cancer and underwent Ivor-Lewis resection assisted by thoracoscopic laparoscopy at the National Cancer Center from October 2019 to April 2022 were collected. The neoadjuvant treatment mode, surgical safety and clinicopathological characteristics were analyzed. Results: Siewert type Ⅱ (92.8%) and adenocarcinoma (95.2%) were predominant in the cases. A total of 2 774 lymph nodes were dissected in 84 patients. The average number was 33 per case, and the median was 31. Lymph node metastasis was found in 45 patients, and the lymph node metastasis rate was 53.6% (45/84). The total number of lymph node metastasis was 294, and the degree of lymph node metastasis was 10.6%(294/2 774). Among them, abdominal lymph nodes (100%, 45/45) were more likely to metastasize than thoracic lymph nodes (13.3%, 6/45). Sixty-eight patients received neoadjuvant therapy before surgery, and nine patients achieved pathological complete remission (pCR) (13.2%, 9/68). Eighty-three patients had negative surgical margins and underwent R0 resection (98.8%, 83/84). One patient, the intraoperative frozen pathology suggested resection margin was negative, while vascular tumor thrombus was seen on the postoperative pathological margin, R1 resection was performed (1.2%, 1/84). The average operation time of the 84 patients was 234.5 (199.3, 275.0) minutes, and the intraoperative blood loss was 90 (80, 100) ml. One case of intraoperative blood transfusion, one case of postoperative transfer to ICU ward, two cases of postoperative anastomotic leakage, one case of pleural effusion requiring catheter drainage, one case of small intestinal hernia with 12mm poke hole, no postoperative intestinal obstruction, chyle leakage and other complications were observed. The number of deaths within 30 days after surgery was 0. Number of lymph nodes dissection, operation duration, and intraoperative blood loss were not related to whether neoadjuvant therapy was performed (P>0.05). Preoperative neoadjuvant chemotherapy combined with radiotherapy or immunotherapy was not related to whether postoperative pathology achieved pCR (P>0.05). Conclusion: Laparoscopic-assisted Ivor-Lewis surgery for esophagogastric junction cancer has a low incidence of intraoperative and postoperative complications, high safety, wide range of lymph node dissection, and sufficient margin length, which is worthy of clinical promotion.

Plurihormonal PIT1-lineage pituitary neuroendocrine tumors: a clinicopathological study / 中华病理学杂志

Objective: To investigate the clinicopathological characteristics of plurihormonal PIT1-lineage pituitary neuroendocrine tumors. Methods: Forty-eight plurihormonal PIT1-lineage tumors were collected between January 2018 and April 2022 from the pathological database of Sanbo Brain Hospital, Capital Medical University. The related clinical and imaging data were retrieved. H&E, immunohistochemical and special stains were performed. Results: Out of the 48 plurihormonal PIT1-lineage tumors included, 13 cases were mature PIT1-lineage tumors and 35 cases were immature PIT1-lineage tumors. There were some obvious clinicopathological differences between the two groups. Clinically, the mature plurihormonal PIT1-lineage tumor mostly had endocrine symptoms due to increased hormone production, while a small number of immature PIT1-lineage tumors had endocrine symptoms accompanied by low-level increased serum pituitary hormone; patients with the immature PIT1-lineage tumors were younger than the mature PIT1-lineage tumors; the immature PIT1-lineage tumors were larger in size and more likely invasive in imaging. Histopathologically, the mature PIT1-lineage tumors were composed of large eosinophilic cells with high proportion of growth hormone expression, while the immature PIT1-lineage tumors consisted of chromophobe cells with a relatively higher expression of prolactin; the mature PIT1-lineage tumors had consistently diffuse cytoplasmic positive staining for keratin, while the immature PIT1-lineage tumors had various expression for keratin; the immature PIT1-lineage tumors showed more mitotic figures and higher Ki-67 proliferation index; in addition, 25.0% (12/48) of PIT1-positive plurihormonal tumors showed abnormal positive staining for gonadotropin hormones. There was no significant difference in the progression-free survival between the two groups (P=0.648) by Kaplan-Meier analysis. Conclusions: Plurihormonal PIT1-lineage tumor belongs to a rare type of PIT1-lineage pituitary neuroendocrine tumors, most of which are of immature lineage. Clinically increased symptoms owing to pituitary hormone secretion, histopathologically increased number of eosinophilic tumor cells with high proportion of growth hormone expression, diffusely cytoplasmic keratin staining and low proliferative activity can help differentiate the mature plurihormonal PIT1-lineage tumors from the immature PIT1-lineage tumors. The immature PIT1-lineage tumors have more complicated clinicopathological characteristics.

Pediatric SMARCB1/INI1-deficient poorly differentiated chordoma of the skull base: report of five cases and review of literature / 中华病理学杂志

Objective: To investigate the clinicopathological characteristics and differential diagnosis of pediatric SMARCB1/INI1-deficient poorly differentiated chordoma (PDC) of the skull base. Methods: Five cases of SMARCB1/INI1-deficient PDC were identified in 139 cases of chordoma diagnosed in Sanbo Brain Institute, Capital Medical University, Beijing, China from March 2017 to March 2021. The clinical and imaging data of the 5 PDCs were collected. H&E and immunohistochemical staining, and DNA methylation array were used, and the relevant literatures were reviewed. Results: All 5 PDCs were located at the clivus. The average age of the patients was 6.4 years, ranging from 3 to 16 years. Three patients were female and two were male. Morphologically, in contrast with classical chordomas, they presented as epithelioid or spindle tumor cells organized in sheets or nests, with necrosis, active mitoses, and infiltration into surrounding tissue. All cases showed positivity of CKpan, EMA, vimentin and brachyury (nuclear stain), and loss of nuclear SMARCB1/INI1 expression. S-100 protein expression was not frequent (2/5). Ki-67 proliferative index was high (20%-50%). All cases had over-expressed p53. It was necessary to differentiate SMARCB1/INI1-dificient PDC from SMARCB1/INI1-dificient tumors occurring at skull base of children or the tumors with epithelial and spindle cell morphological features. The 3 PDCs with DNA methylation testing showed the methylation profiles different from the pediatric atypical teratoid/rhabdoid tumors. They formed an independent methylation profile cluster. The clinical prognosis of the 5 patients was poor, and the overall survival time was 2-17 months. Conclusions: PDC is a special subtype of chordoma, which often affects children and occurs in the clivus. The PDC shares epithelioid or spindle cell morphologic features which are different from the classic chordoma. Besides the typical immunohistochemical profile of chordoma, PDC also has loss of nuclear SMARCB1/INI1 expression and distinct epigenetic characteristics.

Progress of JMJD5 in tumors / 肿瘤研究与临床

JMJD5 belongs to the protein family of JMJD and is closely related to tumorigenesis. JMJD5 plays a carcinogenic role in some tumors, such as oral cancer, prostate cancer, breast cancer, colon cancer and atypical meningiomas, JMJD5 promotes the proliferation, migration and invasion of cancer cells. However, JMJD5 not only plays a carcinogenic role in some tumors, but also plays an anticancer role. For example, in bladder cancer, JMJD5 inhibits the metastasis of bladder cancer; in liver cancer, on the one hand JMJD5 promotes the replication of hepatitis B virus (HBV), and on the other hand it inhibits the growth of cancer cells; in lung cancer, on the one hand JNJD5 promotes the proliferation of cancer cells, and on the other hand it inhibits the metastasis of cancer cells by promoting the stabilization of microtubules. This article will focus on the mechanisms of JMJD5 in tumors, in order to provide a new target for tumor prevention and treatment.

Advances in proteomic studies of post-translational modifications during spermatogenesis / 生理学报

Spermatogenesis is composed of a series of complex biological events, which are regulated by complex factors. There is a phenomenon of delayed translation in spermatogenesis, so the changes of transcription and protein expression are not completely consistent. Thus post-translational modifications (PTMs) play a key role in spermatogenic biological events. In recent years, the development of proteomics has deepened the discovery of PTM. This paper reviews the advances in multiple PTMs proteomic during testicular spermatogenesis. Their effects on sperm function and fertility, as well as their significance for future diagnosis and treatment are discussed.

Current Advances in the Fecal Microbiota Transplantation and Its Application in the Hematologic Diseases--Review / 中国实验血液学杂志

Intestinal microbiome closely relates with human health and disease, which plays a critical role in the immune response, homeostasis, drug metabolism and tumorigenesis. Imbalances in the composition and function of these intestinal microbes associate with diseases. Fecal microbiota transplantation (FMT) is an established successful treatment modality for recurrent Clostridium difficile infection (CDI). The safety profile and potential therapeutic advantages of FMT for diseases associated with dysbiosis and immune dysfunction have led to many publications, mainly case series. The literature on the use of FMT for hematologic diseases is very limited, however, immune thrombocytopenic purpura（ITP）, CDI and aGVHD after HSCT were reported to be improved by FMT. The aim of this review is to briefly summarize the research current state, procedures and clinical application of FMT.

Clinical features and prognosis of acute monocytic leukemia with abnormality of chromosome 8 / 中国实用内科杂志

OBJECTIVE: To investigate the clinical characteristics and prognosis of patients with acute monocytic leukemia(AML-M5)with abnormality of chromosome 8.METHODS: The clinical features of 143 patients with AML-M5 were analyzed retrospectively,and the prognosis factors were analyzed.RESULTS: Out of 143 AML-M5 newly diagnosed patients,37 cases with chromosome 8 aberrations including t(8;21)accounting for 6.99%(10/143),trisomy 8 16.08%(23/143),and other 8 aberrations 2.80%(4/143);73 cases had normal karyotype,and 33 cases possessed non chromosome 8 abnormality.Statistically significant differences did not exist among age,sex,hemogram and bone marrow blasts(P>0.05).However,with chromosome 8 abnormality were predisposed to lower initial white blood cell count(P<0.05).Among 131 patients of receiving chemotherapy,the remission rate after the first course of inducible chemotherapy was 63.36%(83/131)and the one-year survival rate was 61.1%.Analysis of prognostic factors showed that age,the remission after the first induction of chemotherapy(complete remission or no remission),trisomy 8 chromosomal karyotype and treatment regimen(chemotherapy alone or plus hematopoietic stem cell transplantation) had effects on overall survival(P<0.05).Multivariate analysis revealed two independent risk factors:age≥60 years(P<0.05,HR=2.134,95% CI 1.204～3.784)and the complete remission after the first induction of chemotherapy(P<0.05,HR=0.408,95% CI 0.227～0.733).CONCLUSION: Chromosome 8 is easily involved in AML-M5.The patients with involvement of this aberration have lower initial white blood cell count and a poor prognosis.Patients after complete remission have hematopoietic stem cell transplantation is beneficial to prolong survival.

Prognostic Value of Neutrophil to Lymphocyte Ratio for In-hospital Mortality in Elderly Patients with Acute Myocardial Infarction / 华中科技大学学报（医学）（英德文版）

Coronary artery disease (CAD) is a multifactorial disease in which inflammation plays a central role.This study aimed to investigate the association of inflammatory markers such as the neutrophil to lymphocyte ratio (NLR),the Global Registry of Acute Coronary Events (GRACE) score with in-hospital mortality of elderly patients with acute myocardial infarction (AMI) in an attempt to explore the prognostic value of these indices for elderly AMI patients.One thousand consecutive CAD patients were divided into two groups based on age 60.The laboratory and clinical characteristics were assessed retrospectively by reviewing the medical records.The NLR and GRACE score were calculated.In the elderly (≥60 years),patients with non-ST-elevation myocardial infarction (NSTEMI) and ST-elevation myocardial infarction (STEMI) had significantly higher NLR than did those with unstable angina (UA) and stable angina pectoris (SAP) (P＜0.01).The NLR was considerably elevated in older AMI patients compared with their younger counterparts (＜60 years) (P＜0.05).In elderly AMI patients,the NLR was considerably higher in the high-risk group than in both the low-risk and medium-risk groups based on the GRACE score (P＜0.05 and P＜0.01,respectively),and the NLR was positively correlated with the GRACE score (r=0.322,P＜0.001).Either the NLR level or the GRACE score was significantly higher in the death group than in the surviving group (P＜0.05).By curve receiver operator characteristic curve (ROC) analysis,the optimal cut-off levels of 9.41 for NLR and 174 for GRACE score predicted in-hospital death [ROC area under the curve (AUC) 0.771 and 0.787,respectively,P＜0.001].It was concluded that an elevated NLR is a potential predictor of in-hospital mortality in elderly patients with AMI.

Clinical observation of thyroid-related adverse events induced by anti-PD-1 antibody SHR-1210 in patients with advanced solid tumor / 中华肿瘤杂志

Objective@#To assess the incidence and characteristics of thyroid dysfunction during anti-Programmed cell death 1 receptor (PD-1) antibody SHR-1210 therapy in patients with advanced solid tumor.@*Methods@#The medical records of 98 patients who initiated SHR-1210 treatment between April 27, 2016 and June 8, 2017 in the phase 1 trial to evaluate the safety, efficacy, and pharmacokinetics of SHR-1210 in patients with advanced solid tumors were retrospectively reviewed. Serological tests of thyroid stimulating hormone (TSH) and free thyroxine (fT4) were measured at baseline and prior to each SHR-1210 administration.@*Results@#A total of 86 patients had normal thyroid function before the first dose of SHR-1210 treatment. Nine out of 86 (10.5%) patients developed new onset hypothyroidism from euthyroid state. 12 patients presented thyroid dysfunction at baseline, 10 of whom were subclinical hypothyroid and 2 were hypothyroidism. Four out of 10 patients developed hypothyroidism from subclinical hypothyroid. Most patients with hypothyroidism were asymptomatic. Thyroid dysfunction occurred early (median, 55days) after the initiation of SHR-1210. The severity of hypothyroidism were all grade 1-2. No grade 3-4 hypothyroidism occurred. No patients discontinue the treatment of SHR-1210 due to clinical impact of the thyroid dysfunctions.@*Conclusions@#Thyroid-related adverse events were common during anti-PD-1 antibody SHR-1210 treatment . The incidence of hypothyroidism is lower in patients with euthyroid state than in patients with thyroid dysfunction at baseline during SHR-1210 treatment . Thyroid function can be improved after thyroid hormone replacement. During SHR-1210 treatment, it is necessary to pay attention to monitor the thyroid function, especially in the patients with thyroid dysfunction at baseline.@*Trial registration@#Chinese Clinical Trial Registry, 2016L01455

Apoptosis induction and growth inhibition effects of Schisandra chinensis polysaccharides on brain tumor stem cells / 吉林大学学报(医学版)

Objective:To investigate the effect of Schisandra chinensis polysaccharide(SCP)on the growth of brain tumor stem cells(BTSCs),and to clarify the mechanism of inhibiting the growth of BTSCs of SCP. Methods:The primary human glioma cells were cultured,then the BTSCs were isolated by CD133 immunomagnetic sorting.The neural stem cell surface markers CD133 and Nestin were detected by immunofluorescence assay.The proliferation rate of BTSCs was examined by MTT assay.Annexin V-PI analysis was used to analyze the apoptotic rate of BTSCs.The expression levels of Bax,Bcl-2 and Caspase-3 proteins in BTSCs in various groups were detected by ELISA assay.Results:The results of immunofluorescence staining showed that the expressions of CD133 and Nestin were positive in BTSCs.Compared with control group,the proliferation rates of BTSCs in 200,400 and 800 mg·L-1SCP groups were decreased,especially in 400 and 800 mg·L-1SCP groups(P<0.05).The results of Annexin V-PI analysis showed that the apoptotic rate of BTSCs in 800 mg·L-1SCP group was increased compared with control group(P<0.05).The ELISA results showed that the expression levels of Bax in 200,400 and 800 mg·L-1SCP groups were significantly increased(P<0.05),and the values of Bax/Bcl-2 were significantly increased(P<0.05);compared with control group,the Bcl-2 expression level in the BTSCs in 800 mg·L-1SCP group was decreased(P<0.05).The expression level of Caspase-3 protein in 800 mg·L-1SCP group was also significantly increased compared with control group(P<0.01).Conclusion:SCP could inhibit the growth of BTSCs,and the induction of apoptosis may be one of mechanisms.

Clinical Features and Current Treatment Status for In-hospital Elderly Patients With Mitral Regurgitation / 中国循环杂志

Objective: To summarize the clinical features and treatment status for elderly in-hospital patients with mitral regurgitation (MR). Methods: A single center retrospective study was conducted in 1 741 patients admitted in our hospital from 2014-05-01 to 2015-04-30 with echocardiography confirmed moderate to severe MR. The patients were divided into 2 groups: Elderly group, n=680(39.06%)patients≥60 years of age and Non-elderly group,n=1 061(60.94%)patients<60 years.Clinical features and treatment status were studied and compared between 2 groups. Results: The mean age in Elderly group was (66.98±5.94) years and the most common type was degenerative MR (41.18%). Compared with Non-elderly group, Elderly group had more patients combining coronary artery disease (37.79% vs 17.43% ), more risk factors of atherosclerosis such as hypertension (45.44% vs 25.17%), diabetes (19.56% vs 8.48%) and hyperglycemia (35.29% vs 19.51%) all P<0.05; Elderly group had the higher EuroSCORE Ⅱ score (5.54±2.42) vs (3.15±1.66), greater left ventricular end diastolic diameter (57.72±12.37) mm vs (57.33±10.19) mm and less patients combining multiple valve disease (35.59% vs 40.81%), less patients received surgical treatment (54.71% vs 63.9%), all P<0.05. The surgery procedures (mitral valve replacement or mitral-plasty) were similar between 2 groups; compared with Non-elderly group, Elderly group had the higher application rate of bio-prosthetic valve (53.88% vs 18.67%), P<0.001. Conclusion: About 40% in-hospital moderate to severe MR patients were the elderly crowd, the most common pathogenesis was degenerative changes which leaded the higher incidences of cardiac complications, worse cardiac function and the higher risk scores for surgical treatment, there were less patients received surgery.
