Objective Current data are insufficient for comparisons of effectiveness between percutaneous coronary intervention(PCI)and coronary artery bypass grafting(CABG)among patients with coronary artery disease(CAD)and left ventricular dysfunction.Methods A total of 905 CAD patients with reduced left ventricular ejection fraction(LVEF≤35％)in single center of China who underwent either PCI or CABG were enrolled in a real-world cohort study.Clinical outcomes included short-and long-term all-cause mortality,rates of heart failure(HF)hospitalization and repeat revascularization.Propensity score matching was used to balance the 2 cohorts.Results PCI was associated with lower 30-day mortality rate(HR 0.29,95％CI 0.09-0.88,P=0.029).At a mean follow-up of 4.5 years,PCI and CABG had similar all-cause death(HR 1.00,95％CI 0.67-1.50,P=0.990)and HF hospitalization(HR 0.81,95％CI 0.40-1.64,P=0.561),but PCI had higher risk of repeat revascularization(HR 14.46,95％CI 3.43-60.98,P＜0.001).PCI was associated with more significant LVEF improvement than CABG(P=0.031 for interaction).Conclusions CAD patients with reduced LVEF who underwent PCI had lower short-term mortality rate and more LVEF improvement but higher risk of repeat revascularization during follow-up than patients who underwent CABG.PCI showed comparable long-term survival and HF hospitalization risk.

Objective To explore the factors that affect the excretion rate of methotrexate and the occurrence of adverse reactions in high-dose methotrexate chemotherapy for osteosarcoma patients.Methods Retrospectively analyzed methotrexate excretion,liver injury,kidney injury,bone marrow suppression and other adverse drug reactions in 97 high-dose methotrexate chemotherapy cycles of 28 patients with osteosarcoma.The concentration of methotrexate in the blood at 0,24,48,72 h and the level of white protein in the blood were also analyzed.Results When the peak concentration of methotrexate(0h,Cmax)≥700 μmol·L-1 the risk of excretion delay increases:the incidence was 23.21％in group with Cmax ≥ 700 μmol·L-1,and it was 5.00％in group with Cmax＜700 μmol·L-1,(P＜0.05),but when the peak concentration was≥1 000 μmol·L-1,the risk of delayed excretion did not increase further:the incidence was 16.00％in group with Cmax 1 000 μmol·L-1,and it was 15.49％in group with Cmax＜1 000 μmol·L-1,(P＞0.05).Methotrexate blood Cmax has no significant correlation with the occurrence of important adverse reactions such as liver injury and bone marrow suppression.There was significant correlation between low serum albumin level and bone marrow suppression in patients.The average albumin level in group with bone marrow suppression was(39.1±3.4)g·L-1,which in without bone marrow suppression group was(41.2±4.0)g·L-1(P＜0.05).Conclusion During high-dose methotrexate chemotherapy in patients with osteosarcoma,delayed excretion and adverse reactions should not be prevented by lowering the peak concentration.The albumin level of patients is an important factor affecting the occurrence of bone marrow suppression.

OBJECTIVE: To investigate the application effect of sequential autologous hematopoietic stem cell transplantation (Auto-HSCT) with lenalidomide, bortezomib and dexamethasone (RVD) in the treatment of multiple myeloma (MM) evaluated by propensity score matching. METHODS: The clinical data of 49 MM patients treated with RVD scheme and followed-up for 36 months in the hospital from January 2015 to January 2021 were retrospectively analyzed and included in the control group, the clinical data of 54 MM patients who received RVD scheme and sequential Auto-HSCT scheme and completed 36 months of follow-up in the hospital during the same period were collected and included in the observation group. PSM method (1∶1, caliper value=0.01) was used to match the control group with the observation group based on baseline data and laboratory indexes, covariate equilibrium samples were obtained between groups (40 cases in each group). The clinical efficacy of patients in the two groups after 18 weeks of treatment was compared; the incidence of toxic and side effects during treatment of patients in the two groups was compared; the survival of patients in the two groups was compared after 36 months of follow-up. RESULTS: The ORR and DCR in the observation group were higher than those in the control group, the difference was statistically significant (P<0.05). Compared the incidence of fatigue, rash, thrombocytopenia, anemia and nausea of patients in the two groups, there was no statistical significant difference (P>0.05). After 36 months of follow-up (no loss during follow-up), 4 cases died from illness in the observation group, with a survival rate of 90% and an average survival time of 35.61 (95% CI: 35541-35.685) months, 10 cases died from illness in the control group, with a survival rate of 75% and an average survival time of 34.70 (95% CI: 34.559-34.832) months, the survival rate of the observation group was higher than that of the control group, the difference was statistically significant (P<0.05). CONCLUSION Sequential Auto-HSCT with RVD regimen in the treatment of MM can improve the short-term efficacy and increase the survival rate of patients, which will not increase toxic and side effects and has high safety.

Objective: To summarize the clinical features, management and outcome of superior vena cava syndrome (SVCS) associated with mediastinal malignancy in children. Methods: Clinical data of 42 children of SVSC associated with mediastinal malignancy in Shanghai Children's Medical Center from January 2015 to December 2021 were collected and analyzed retrospectively. The clinical manifestations, pathological diagnosis, disease diagnosis process, and prognosis were summarized. Results: Among 42 children of SVCS associated with mediastinal malignancy, there were 31 males and 11 females. The age at diagnosis was 8.5 (1.9, 14.9) years. Cough and wheezing (33 cases, 79%), orthopnea (19 cases, 45%) and facial edema (18 cases, 43%) occurred most commonly. T-cell lymphoblastic lymphoma (T-LBL) was the most frequent pathological diagnosis (25 cases, 60%), followed by T-cell acute lymphoblastic leukemia (T-ALL) (7 cases, 17%), anaplastic large cell lymphoma (4 cases, 10%) and diffuse large B-cell lymphoma (2 cases, 5%), peripheral T-lymphoma, Hodgkin lymphoma, Ewing's sarcoma and germ cell tumor (1 case each). Pathological diagnosis was confirmed by bone marrow aspiration or thoracentesis in 14 cases, peripheral lymph node biopsy in 6 cases, and mediastinal biopsy in 22 cases. Twenty-seven cases (64%) had local anesthesia. Respiratory complications due to mediastinal mass developed in 3 of 15 cases who received general anesthesia. Of the 42 cases, 27 cases had sustained remission, 1 case survived with second-line therapy after recurrence, and 14 cases died (2 cases died of perioperative complications and 12 cases died of recurrence or progression of primary disease). The follow-up time was 36.7 (1.2, 76.1) months for 27 cases in continuous complete remission. The 3-year overall survival (OS) and events free survival (EFS) rates of 42 children were 59% (95%CI 44%-79%) and 58% (95%CI 44%-77%) respectively. Conclusions: SVCS associated with mediastinal malignancy in children is a life-threatening tumor emergency with high mortality. The most common primary disease is T-LBL. The most common clinical symptoms and signs are cough, wheezing, orthopnea and facial edema. Clinical management should be based on the premise of stable critical condition and confirm the pathological diagnosis through minimal invasive operation.

OBJECTIVES: The epidemic of acquired immune deficiency syndrome (AIDS) among men who have sex with men (MSM) is severe in China. And MSM has now become a key population for the infection and transmission of AIDS. At present, the bottleneck of AIDS prevention and control among MSM population is low rate of continuous condom use and high incidence of unsafe sexual behavior. Inductive summarization of the literature revealed that the most critical reason for low rate of continuous condom use among the MSM population was condom-related stigma. Although many studies mentioned condom-related stigma among MSM populations, there has been no any definition of MSM-related condom stigma and no measurement for it. Therefore, the paper aims to explore barriers to condom use among MSM, then construct the conceptual and operational definition of "MSM-related condom stigma" through Meta synthesis and concept synthesis, and provide a new perspective for AIDS prevention and control among MSM. METHODS: Based on evidence-based method, "PICoS" framework and Meta-synthesis was used to include the literatures. Then, we used synthesized qualitative evidence from included studies to construct the concept and operational definition of MSM-related condom stigma by the means of thematic analysis and concept synthesis. RESULTS: According to the results of the concept synthesis, MSM-related condom stigma refers to any taboos or misbeliefs about condom use or feeling ashamed or embarrassed to talk about using condoms which perceived by individuals at the individual, interpersonal, and social levels.It was demonstrated through 4 sub-themes at operational level: a symbol of distrust, a symbol of HIV/sexual transmitted infections (STIs) prevention, a symbol of an embarrassing topic, and a symbol of violating the traditional cognition of sexual intercourse. According to the Social-ecological Model (SEM), a symbol of distrust refers to that the MSM population believes that not using condoms represents mutual trust between sexual partners, while using condoms is difficult to express intimacy, trust and loyalty between sexual partners. A symbol of HIV/STIs prevention at the interpersonal level refers to that the MSM population believes that condom use is a "symbol" for the prevention or infection of AIDS; on the one hand, if someone proposes to use condoms, he may be considered infected with HIV or have unsafe sex experiences, thus, making it difficult to propose condom use; on the other hand, if they believe that sexual partners are "AIDS free" (often a wrong perception, such as sexual partners may have the risk of AIDS infection although they do not have AIDS), it is considered that condom use is completely unnecessary. The environmental level includes a symbol of an embarrassing topic and a symbol of violating the traditional cognition of sexual intercourse. A symbol of an embarrassing topic refers to the MSM population feels shame about topics related to sexual behavior and is embarrassed to carry/buy/propose condom use or be ashamed to engage in conversations about whether to use condoms during sexual behavior. And a symbol of violating the traditional cognition of sexual intercourse: The MSM population have limitations in their perception of "sex" or "sexual behavior" and believe that real sex (behavior) is unobstructed contact between the bodies and exchange between all body fluids. CONCLUSIONS The concept of MSM-related condom stigma is proposed for the first time, and its operational definition is given. The concept includes 3 levels and 4 dimensions. It is helpful to understand MSM people's attitude and cognition towards condoms, and adds indicators with cultural sensitivity and behavioral sensitivity to the behavioral intervention for AIDS in the future.

Objective To investigate the epidemiological characteristics and identify the risk factors of Giardia lamblia infections among patients with colorectal cancer in Henan Province. Methods A cross-sectional study was performed for questionnaire surveys among colorectal cancer patients in Henan Cancer Hospital during the period from March to July, 2021. Patients’ stool samples were collected, and the triosephosphate isomerase (tpi) gene of G. lamblia was amplified in stool samples using nested PCR assay to characterize the parasite genotype. Univariate analysis and multivariate logistic regression analyses were employed to identify the risk factors of G. lamblia infections among colorectal cancer patients. Results A total of 307 colorectal cancer patients were investigated, including 176 males (57.3%) and 131 females (42.7%). PCR assay detected 8.1% [95% confidential interval (CI): (0.056, 0.117)] prevalence of G. lamblia infections among the study subjects, and there was no significant difference in the prevalence between men [9.1%, 95% CI: (0.057, 0.143)] and women [6.9%, 95% CI: (0.037, 0.125)] (χ² = 0.495, P = 0.482). In addition, there was no age-specific prevalence of G. lamblia infections among the participants (χ² = 1.534, P = 0.675). Multivariate logistic regression analysis identified use of septic tanks [odds ratio (OR) = 3.336, 95% CI: (1.201, 9.267)], daily use of well water [OR = 3.042, 95% CI: (1.093, 8.465)] and raising livestock [OR = 3.740, 95% CI: (1.154, 12.121)] as risk factors of G. lamblia infections among colorectal cancer patients, and the prevalence of abdominal pain was significantly greater in colorectal cancer patients with G. lamblia infections than in those without infections (P = 0.017). Among the 25 patients with G. lamblia infections, assemblage A was characterized in 24 (96.0%) cases and assemblage B in one case (4.0%). Conclusions The prevalence of G. lamblia is high among colorectal cancer patients in Henan Province, and assemblage A is the dominant genotype of G. lamblia. Use of septic tanks, daily use of well water and raising livestock are risk factors of G. lamblia infections among patients with colorectal cancer.

BACKGROUND: A novel coronavirus called severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), first identified in Wuhan, China, has been rapidly spreading around the world. This study investigates the epidemiological and clinical characteristics of coronavirus disease 2019 (COVID-19) patients in Zhejiang Province who did or did not have a history of Wuhan exposure. METHODS: We collected data from medical records of confirmed COVID-19 patients in Zhejiang Province from Jan. 17 to Feb. 7, 2020 and analyzed epidemiological, clinical, and treatment data of those with and without recorded recent exposure in Wuhan. RESULTS: Patients in the control group were older than those in the exposure group ((48.19±16.13) years vs. (43.47±13.12) years, P<0.001), and more were over 65 years old (15.95% control vs. 5.60% exposure, P<0.001). The rate of clustered onset was also significantly higher in the control group than in the exposure group (31.39% vs. 18.66%, P<0.001). The symptom of a sore throat in patients in the exposure group was significantly higher than that in the control group (17.30% vs. 10.89%, P=0.01); however, headache in the exposure group was significantly lower than that in the control group (6.87% vs. 12.15%, P=0.015). More patients in the exposure group had a significantly lower level of lactate dehydrogenase (LDH) and aspartate aminotransferase (AST) than those in the control group. There was no significant difference in any degree of COVID-19 including mild, severe, and critical between the two groups. CONCLUSIONS From the perspective of epidemiological and clinical characteristics, there was no significant difference between COVID-19 patients with and without Wuhan exposure history.
