ABSTRACT
Objective:To investigate the correlation between the number of circulating DLBCL cell and the marrow tumor cell burden and the prognostic indicators in patients with DLBCL, and to evaluate the feasibility of circulating DLBCL cell reflecting the marrow tumor burden and disease progression. Optimization of FCM for screening circulating DLBCL cell was done to monitor MRD and recurrence.Methods:We conducted a retrospective study in 75 diagnosed DLBCL patients in the First Affiliated Hospital of Zhengzhou University from June 2020 to February 2021, including 43 males and 32 females aged 61 (37-85) years. According to the diagnosis and treatment criteria, the patients were divided into initial and recurrence group ( n = 53), partial response(PR)group ( n=14) and complete response(CR)group ( n=8). According to the positive criteria of circulating DLBCL cells, 48 cases were divided into circulating DLBCL positive group and 27 cases were negative group. 30 anemia patients with non-B-cell tumor-related diseases were selected as the control group, including 16 males and 14 females, aged 52 (30-79) years. 70 healthy subjects, including 36 males and 34 females, aged 39 (25-57), were selected for methodology optimization. FCM was used to detect the ratio of marrow and circulating DLBCL cells in each group, and analyze the connection between circulating DLBCL cells and clinical indicators. Statistical analysis was performed using t test, χ 2 test, Kruskal-Wallis H test, Spearman rank correlation, and Logistic regression. Results:(1) Bone marrow and circulating DLBCL cells were not detected in CR group and control group; The positive rate of circulating DLBCL cells in the initial/recurrent group and PR groups was 75.47% and 57.14%, respectively. The proportion of bone marrow and circulating DLBCL cells was positively correlated in the two groups ( P value was <0.001 and 0.020, respectively). (2) The proportion of bone marrow and circulating DLBCL cells in the initial and recurrent groups, PR group, CR group and control group decreased successively ( P<0.05). The proportion of DLBCL cells was 27.72% (initial and recurrent bone marrow group), 26.92% (initial and recurrent circulating group), 3.23% (bone marrow PR group) and 1.67% (circulating PR group), respectively. (3) Compared with the negative group, the circulating DLBCL cell positive group had increased LDH, β 2-MG, and CMYC expression(≥80%), with decreased LYM, HGB<100 g/L, B symptoms, PD-L1 expression, and age ≥60 years, showing higher ECOG, aaIPI/IPI scores and Ann staging ( P<0.05). Age ≥60, B symptoms, and PD-L1 expression were independent risk factors for circulating DLBCL cells ( P<0.05). Conclusions:The detectable rate of circulating DLBCL cell could be improved by optimizing the preoperative treatment conditions of FCM. Circulating DLBCL cells can reflect the tumor burden and disease progression. Detecting circulating DLBCL cells may improve patients′ compliance.
ABSTRACT
Objective@#To systematic evaluate the real experience of patients after falling during hospitalization and qualitative research on the cognition and demand for fall prevention will provide theoretical basis for patients, their families, medical staff and medical institutions to better carry out fall prevention.@*Methods@#English databases such as PsycINFO, Medline, Embase, CINAHL, Cochrane, PubMed, and Chinese databases such as Chinese biomedical literature database, CNKI, Wanang database were retrieved by computer. Included qualitative studies on the emotional experience of fall of inpatients and their cognition and needs for fall prevention. The retrieval time limit was until November 1, 2018.The literature was evaluated using the quality evaluation criteria for qualitative research (2016) of the JBI evidence-based health care center, and the results were integrated using a pooled integration method.@*Results@#A total of 8 studies were included, and 33 clear research results were extracted. Similar results were summarized and combined to form 7 new categories, which were integrated into 4 results. Results 1: psychological experience of hospitalized patients after falling down. Integration results 2: the causes of falls from the perspective of inpatients. Integration results 3: hospital fall prevention measures and evaluation from the perspective of inpatients. Integration result 4: inpatients expected to receive care from their families and help from medical staff.@*Conclusion@#Fall events seriously affect the mental health of patients; Patients′ cognition of falling is affected and changed by many factors. Fall prevention should shift from clinical focus to patient-centered and attach importance to the participation of family members.
ABSTRACT
Objective To assess the current status and factors associated with the mental health condition of older adults. Methods A convenience sampling survey was conducted using symptom check list 90 (SCL-90) among the Chinese older adults aged 60 or above from January to March, 2018. The older adults aged 80 or above were selected for this study. Chi-square test and binary logistic regression model were used to analyze the influencing factors. Results The total participants were 485. The SCL-90 positive detection rate was 20.21%. The symptoms of the four highest detection rates were somatization (39.38%), others (25.15%), obsessive-compulsive symptoms (24.33%) and depression (22.68%). The older adults with normal BMI (OR=0.537, 95% CI: 0.250-0.857, P=0.027) and lived in county town (OR=0.224, 95% CI:0.075-0.667, P=0.007) showed lower SCL-90 positive detection rate. These who had been educated for 1-5 years (OR=11.092, 95% CI: 4.446-27.671, P<0.001), 6-8 years (OR=9.800, 95% CI: 3.464-27.721, P<0.001), 9~11 years (OR=19.279, 95% CI : 6.722-55.297, P<0.001), 12 years and above (OR=24.321, 95% CI: 7.894-74.929, P<0.001) had higher SCL-90 positive detection rate compared with those who were uneducated. Conclusion The mental health condition of Chinese older adults is mainly influenced by residence place, education level, family income self-evaluation and BMI status.
ABSTRACT
Scutellariae Radix (SR), the root of Scutellaria baicalensis Georgi, is used as an antipyretic drug and has been demonstrated to have anti-inflammatory activity. SR is divided into two specifications, "Ku Qin" (KQ) and "Zi Qin" (ZQ), for use against different symptoms (upper energizer heat or lower portion of the triple energizer), according to the theory of traditional Chinese medicine (TCM). However, differences in the efficacies of these two specifications have not been determined. In the present study, we aimed to characterize the differences in the anti-inflammatory activities between KQ and ZQ and to explore how their differences are manifested in lipopolysaccharide (LPS)-induced macrophages. Our results showed that, in RAW264.7 cells (a mouse macrophage cell line derived from ascites), KQ and ZQ displayed anti-inflammatory effects by inhibiting the release of nitric oxide (NO), inducible NOS (iNOS), and nuclear factor-κB (NF-κB) in a dose-dependent manner without distinction. In NR8383 cells (a rat alveolar macrophage cell line), KQ and ZQ displayed similar effects on NO, iNOS, and NF-κB as seen in RAW264.7 cells, but KQ showed a higher inhibition rate for NO and iNOS than that shown by ZQ at the same concentration. These results indicated that there were differences in efficacy between KQ and ZQ in treating lung inflammation. Our findings provided an experimental evidence supporting the different uses of KQ and ZQ in clinic, as noted in ancient herbal records.

The plants in genus Ypsilandra Franch (Liliaceae) have similar chemical constituents and pharmacological activities with Paris L., the major active ingredients of them are steroidal saponins, and their pharmacological effects include antibacterial, antitumor, and hemostasis. Therefore, Ypsilandra thibetica could replace Paris L. to some extent and alleviate its crisis. In this paper, the research progress of the current studies of Y. thibetica is summarized. It may provide the reference for the further studies of this plant.
ABSTRACT
Objective To study the efficacy and safety of low-dose azithromycin with tiotropium bromide in the treatment of stable chronic obstructive pulmonary disease.Methods A hundred and ten patients were randomized into three groups:tiotropium bromide group (36 cases,group A),azithromycin with tiotropium bromide group(38 cases,group B)and control group(36 cases,group C).Patients in group A were given tiotropium bromide (18 μg,q,d )in addition to conventional treatment.The patients in group B were given lowdose azithromycin (250 mg,twice a week) in combined with tiotropium bromide.The patients in control group were given the conventional treatment only.The courses of treatment lasted for six months.Results Compared with the control group,the frequency of acute exacerbation in patients treated with azithromycin and tiotropium bromide was reduced remarkably ( 2.1 ± 0.6 and 4.9 ± 0.7,t =18.5061,P ＜ 0.05 ).The severity of clinic symptoms ( Cough 1.3 ± 0.5 vs.2.2 ± 0.6,P ＜ 0.05 ),expectoration ( 1.0 ± 0.2 vs.1.7 ± 0.3,P ＜ 0.05 ),anhelation ( 1.5 ± 0.8 vs.2.1 ± 0.6,t =3.6342,P ＜ 0.001 ) ],life quality ( 29 ± 8 vs.42 ± 11,P ＜ 0.05 ) and six-minutes walking distance( [ 370.00 ± 14.26 ] m vs.[ 290.00 ± 12.85 ] m,P ＜ 0.05 ) of the azithromycin with tiotropium bromide group were improved significantly when compared with control.Compared with the tiotropium bromide group,the frequency of acute exacerbation ( 2.1 ± 0.6 vs.3.2 ± 0.8,P ＜ 0.05 ),the severity of clinic symptoms (Cough 1.3 ±0.5 vs.1.8 ±0.4,P＜0.05),expectoration( 1.0 ±0.2 vs.1.3 ±0.3,P ＜0.05) and anhelation( 1.5 ±0.8 vs.1.9 ± 0.6,P ＜ 0.05 ) ],life quality ( 29 ± 8 vs.36 ± 10,P ＜ 0.05 ) and six-minutes walking distance ( [ 370.00 ± 14.26 ] m vs.[ 330.00 ± 13.76 ] m,P ＜ 0.05 ) were improved over those of tiotropium bromide group.Conclusion The long-term low-dose azithromycin in combinned with tiotropium bromide is good and safe in treating stable COPD.Therefore,it is worth of further clinical evaluation.
