RESUMEN

@#Objective    To investigate the clinical effect of 3D computed tomography bronchial bronchography and angiography (3D-CTBA) and guidance of thoracoscopic anatomic pulmonary segmentectomy by Mimics software system. Methods    A retrospective analysis was performed on patients who underwent thoracoscopic segmentectomy in the Department of Thoracic Surgery of Affiliated People's Hospital of Jiangsu University from June 2020 to December 2022. The patients who underwent preoperative 3D-CTBA using Materiaise's interactive medical image control system (Mimics) were selected as an observation group, and the patients who did not receive 3D-CTBA were selected as a control group. The relevant clinical indicators were compared between the two groups. Results    A total of 59 patients were included, including 29 males and 30 females, aged 25-79 years. There were 37 patients in the observation group, and 22 patients in the control group. The operation time (163.0±48.7 min vs. 188.8±43.0 min, P=0.044), intraoperative blood loss [10.0 (10.0, 20.0) mL vs. 20.0 (20.0, 35.0) mL, P<0.001], and preoperative puncture localization rate (5.4% vs. 31.8%, P=0.019) in the observation group were better than those in the control group. There was no statistically significant difference in the thoracic tube placement time, thoracic fluid drainage volume, number of intraoperative closure nail bin, postoperative hospital stay, or postoperative air leakage incidence (P>0.05) between the two groups. Conclusion    For patients who need to undergo anatomical pulmonary segmentectomy, using Mimics software to produce 3D-CTBA before surgery can help accurately identify pulmonary arteriovenous anatomy, reduce surgical time and intraoperative blood loss, help to determine the location of nodules and reduce invasive localization before surgery, and alleviate patients' pain, which is worthy of clinical promotion.

RESUMEN

ObjectiveTo study the genetic diversity and genetic relationship of Pinellia ternata germplasm resources and provide the basis for germplasm identification, variety breeding, and resource conservation. MethodIn this study, 27 P. ternata were used as experimental materials to determine seven phenotypic characters, such as plant height, leaf length, and leaf width. Simple sequence repeats (SSR) primers were designed based on P. ternata transcriptome data, and polymerase chain reaction (PCR) amplification was performed on 27 P. ternata samples. The genetic diversity of P. ternata germplasm was analyzed by POPGENE32, PowerMarker V3.25, and NTSYS-PC 2.10e software. ResultA total of 10 pairs of highly polymorphic primers (PIC>0.5) and four pairs of moderately polymorphic primers (0.25<PIC<0.5) were selected. The average number of alleles detected was 3.928 6, and the average Nei's diversity index (H) and Shannon's index (I) were 0.557 8 and 1.002 9, respectively, indicating a high level of genetic diversity. Cluster analysis divided the Pinellia ternata into seven categories, and P. ternata in the same province were in the same categories. The SSR molecular ID cards of 27 P. ternata germplasm were constructed with 14 pairs of primers, and the rapid identification of P. ternata in each region was realized. ConclusionThe results of this study can lay a foundation for the genetic diversity and population structure of P. ternata and provide a scientific basis for the identification of P. ternata germplasm resources, map construction, and molecular-assisted breeding.

RESUMEN

ObjectiveTo investigate the therapeutic effect of Baihe Wuyaotang (BWT) on non-alcoholic fatty liver disease (NAFLD) and elucidate its underlying mechanism. MethodC57BL/6J mice were randomly assigned to six groups: normal control, model, positive drug (pioglitazone hydrochloride 1.95×10-3 g·kg-1), and low-, medium-, and high-dose BWT (1.3,2.5 and 5.1 g·kg-1). Following a 12-week high-fat diet (HFD) inducement, the mice underwent six weeks of therapeutic intervention with twice-daily drug administration. Body weight was monitored weekly throughout the treatment period. At the fifth week, glucose tolerance (GTT) and insulin tolerance (ITT) tests were conducted. Subsequently, the mice were euthanized for the collection of liver tissue and serum, and the subcutaneous adipose tissue (iWAT) and epididymal adipose tissue (eWAT) were weighed. Serum levels of total triglycerides (TG) and liver function indicators,such as alanine aminotransferase (ALT) and aspartate aminotransferase (AST), were determined. Histological examinations, including oil red O staining, hematoxylin-eosin (HE) staining, Masson staining, and transmission electron microscopy, were performed to evaluate hepatic lipid deposition, pathological morphology, and ultrastructural changes, respectively. Meanwhile, Western blot and real-time quantitative polymerase chain reaction (Real-time PCR) were employed to analyze alterations, at both gene and protein levels, the insulin signaling pathway molecules, including insulin receptor substrate 1/2/protein kinase B/forkhead box gene O1 (IRS1/2/Akt/FoxO1), glycogen synthesis enzymes phosphoenolpyruvate carboxy kinase (Pepck) and glucose-6-phosphatase (G6Pase), lipid metabolism-related genes stearoyl-coA desaturase-1 (SCD-1) and carnitine palmitoyltransferase-1 (CPT-1), fibrosis-associated molecules α-smooth muscle actin (α-SMA), type Ⅰ collagen (CollagenⅠ), and the fibrosis canonical signaling pathway transforming growth factor-β1/drosophila mothers against decapentaplegic protein2/3(TGF-β1/p-Smad/Smad2/3), inflammatory factors such as interleukin(IL)-6, IL-8, IL-11, and IL-1β, autophagy markers LC3B Ⅱ/Ⅰ and p62/SQSTM1, and the expression of mammalian target of rapamycin (mTOR). ResultCompared with the model group, BWT reduced the body weight and liver weight of NAFLD mice(P<0.05, P<0.01), inhibited liver lipid accumulation, and reduced the weight of white fat: it reduced the weight of eWAT and iWAT(P<0.05, P<0.01) as well as the serum TG content(P<0.05, P<0.01). BWT improved the liver function as reflected by the reduced ALT and AST content(P<0.05, P<0.01). It improved liver insulin resistance by upregulating IRS2, p-Akt/Akt, p-FoxO1/FoxO1 expressions(P<0.05). Besides, it improved glucose and lipid metabolism disorders: it reduced fasting blood glucose and postprandial blood glucose(P<0.05, P<0.01), improved GTT and ITT(P<0.05, P<0.01), reduced the expression of Pepck, G6Pase, and SCD-1(P<0.01), and increased the expression of CPT-1(P<0.01). The expressions of α-SMA, Collagen1, and TGF-β1 proteins were down-regulated(P<0.05, P<0.01), while the expression of p-Smad/Smad2/3 was downregulated(P<0.05), suggesting BWT reduced liver fibrosis. BWT inhibited inflammation-related factors as it reduced the gene expression of IL-6, IL-8, IL-11 and IL-1β(P<0.01) and it enhanced autophagy by upregulating LC3B Ⅱ/Ⅰ expression(P<0.05)while downregulating the expression of p62/SQSTM1 and mTOR(P<0.05). ConclusionBWT ameliorates NAFLD by multifaceted improvements, including improving IR and glucose and lipid metabolism, anti-inflammation, anti-fibrosis, and enhancing autophagy. In particular, BWT may enhance liver autophagy by inhibiting the mTOR-mediated signaling pathway.

RESUMEN

ObjectiveTo explore the influence of future time insight on academic procrastination and the role of self-control among secondary vocational students, and to provide references for mental health education of them. MethodsA total of 1 419 secondary vocational students from 2 secondary vocational schools in Huangshan City Anhui Province were selected as the research objects in June 2022. The future time insight questionnaire for adolescents, the academic procrastination questionnaire for middle school students and the Self-Control Scale (SCS) were used to assess the future time insight, academic procrastination and self-control ability of secondary vocational students. The mediating effect test of PROCESS was used to analyze the mediating role of self-control between future time insight and academic procrastination. Results①There was a positive correlation between the future time insight questionnaire for adolescents score, the SCS score and the academic procrastination questionnaire of middle school students score (r=0.558, 0.470, P<0.01). ②Both future time insight and self-control could positively predict academic procrastination (β=0.463, 0.218, P<0.01), while future time insight could positively predict self-control (β=0.348, P<0.01). ③Self-control partially mediated the relationship between future time insight and academic procrastination [indirect effect=0.076 (95% CI: 0.052~0.101, P<0.01), and the indirect effect accounted for 16.41% of the total effect]. ConclusionThe future time insight of secondary vocational students can affect academic procrastination directly or indirectly through self-control, which partially mediates the relationship between future time insight and academic procrastination.

RESUMEN

Objective: To understand the current situation of long working hours exposure of couriers in Zhejiang Province, and to analyze the influence of long working hours exposure levels on their occupational stress and depression symptoms, and provide a basis for promoting the physical and mental health of couriers. Methods: From September to December 2021 , 1159 couriers from Zhejiang Express Transport Companies were selected as respondents by cluster sampling, and their basic information were collected. The occupational stress and depression symptoms of the couriers were assessed using the Core Occupational Stress Scale (COSS) and the Patient Health Questionnaire-9 (PHQ-9). The effects of long work hours (>48 h per week) on the occupational stress and depression symptoms of the couriers were analyzed. Results: The average age of 1159 courier in Zhejiang Province was (33.24±8.42) years, the average weekly working hours were (63.21±18.77) h, and 75.15% (871/1159) were long-term workers. The detection rates of occupational stress and depression symptoms in courier were 32.44% (376/1159) and 32.53% (377/1159), respectively. There were significant differences in the detection rates of occupational stress and depression symptoms among couriers with different ages, educational background, marital status, monthly average income, length of service, position or post, shift status, drinking status, and average weekly working hours (P <0.05). The adjusted logistic regression analysis showed that, after adjusting for the influence of confounding factors such as age, educational background, marital status, monthly average income, length of service, position or post, shift status and drinking status, compared with the weekly working hours ≤48 h, weekly working hours of 63-77 h, 78-92 h, ≥93 h were the risk factors for occupational stress (OR=1.547, 95%CI: 1.019-2.350; OR=1.886, 95%CI: 1.184-3.006; OR=2.338, 95%CI: 1.188-4.062) and depression symptoms (OR=1.897, 95%CI: 1.258-2.860; OR=2.041, 95%CI: 1.290-3.230; OR=4.978, 95%CI: 2.551-9.715) of couriers (P<0.05) . Conclusion: Long working hours could increase the risk of occupational stress and depression symptoms among couriers. It is necessary to arrange working hours reasonably to reduce the occurrence of occupational stress and depression symptoms of couriers.

RESUMEN

Objective: To analysis the clinical characteristics of 400 fetuses with heart defects and the impactors of pregnancy decision making, and explore the influence of a multi-disciplinary team (MDT) cooperation approach on it. Methods: Clinical data of 400 fetuses with abnormal cardiac structure diagnosed at Peking University First Hospital from January 2012 to June 2021 were collected, which were divided into 4 groups according to the characteristics of fetal heart defects and the presence of extracardiac abnormalities or not: single cardiac defects without extracardiac abnormalities (122 cases), multiple cardiac defects without extracardiac abnormalities (100 cases), single cardiac defects with extracardiac abnormalities (115 cases), and multiple cardiac defects with extracardiac abnormalities (63 cases). The types of fetal cardiac structural abnormalities and genetic test results, and the detection rate of pathogenic genetic abnormalities, MDT consultation and management situation, and pregnancy decision of fetuses in each group were retrospectively analyzed. A logistics regression was used to analyze the influencing factors of fetal heart defects pregnancy decision. Results: (1) Among the 400 fetal heart defects, the four most common major types were ventricular septal defect 96 (24.0%, 96/400), tetralogy of Fallot 52 (13.0%, 52/400), coarctation of the aorta 34 (8.5%, 34/400), and atrioventricular septal defect 26 (6.5%, 26/400). (2) Among the 204 fetuses undergoing genetic examination, 44 (21.6%, 44/204) pathogenic genetic abnormalities were detected. (3) Detection rate of pathogenic genetic abnormalities (39.3%, 24/61) and pregnancy termination rate (86.1%, 99/115) in the single cardiac defects with extracardiac abnormalities group were significantly higher than those in the single cardiac defects without extracardiac abnormalities group [15.1% (8/53), 44.3% (54/122), respectively] and the multiple cardiac defects without extracardiac abnormalities group [6.1% (3/49), 70.0% (70/100), respectively, both P<0.05], and the pregnancy termination rate in the multiple cardiac defects without extracardiac abnormalities group and the multiple cardiac defects with extracardiac abnormalities group (82.5%,52/63) were significantly higher than that of the single cardiac abnormalities without extracardiac abnormalities group (both P<0.05). (4) After adjusting for age, gravity, parity and performed prenatal diagnosis, maternal age, the diagnosis of gestational age, prognosis grades, co-existence of extracardiac abnormalities, presence of pathogenic genetic abnormalities, and receiving MDT consultation and management were still independent influencing factors of termination of pregnancy of fetuses with cardiac defects (all P<0.05). A total of 29 (7.2%, 29/400) fetal cardiac defects received MDT consultation and management, and compared with those without MDT management, the pregnancy termination rate in the multiple cardiac defects without extracardiac abnormalities group [74.2%(66/89) vs 4/11] and the multiple cardiac defects with extracardiac abnormalities group [87.9%(51/58) vs 1/5] were lower, the differences were statistically significant respectively (all P<0.05). Conclusions: Maternal age, diagnosed gestational age, severity of cardiac defects, extracardiac abnormalities, pathogenic genetic abnormalities and MDT counseling and management are the influencing factors of fetal heart defects pregnancy decision. MDT cooperation approach influences pregnancy decision-making and should be recommended for the management of fetal cardiac defect to reduce unnecessary termination of pregnancy and improve pregnancy outcomes.

RESUMEN

An epidemiological investigation was conducted on a cluster epidemic of COVID-19 in the vaccinated population in Beijing in 2022, and serum samples were collected from 21 infected cases and 61 close contacts (including 20 cases with positive nucleic acid in the isolation observation period). The results of antibody detection showed that the IgM antibody of two infected persons was positive, and the IgG antibody positive rates of patients who were converted, not converted to positive and infected persons were 36.84% (7/19), 63.41% (26/41) and 71.43% (15/21), respectively. About 98.78% of patients had been vaccinated with the SARS-CoV-2 inactivated vaccine. The positive rate of IgG antibody in patients immunized with three doses of vaccine was 86.00% (43/50), which was higher than that in patients with one or two doses [16.12% (5/31)]. The antibody level of M (Q1, Q3) in patients immunized with three doses was 4.255 (2.303, 7.0375), which was higher than that in patients with one or two doses [0.500 (0.500, 0.500)] (all P values<0.001). The antibody level of patients who were vaccinated less than three months [7.335 (1.909, 7.858)] was higher than that of patients vaccinated more than three months after the last vaccination [2.125 (0.500, 4.418)] (P=0.007). The positive rate and level of IgG antibody in patients who were converted to positive after three doses were 77.78% (7/9) and 4.207 (2.216, 7.099), respectively, which were higher than those in patients who were converted after one or two doses [0 and 0.500 (0.500, 0.500)] (all P values<0.05).

RESUMEN

Efforts have been made to establish various human pluripotent stem cell lines. However, such methods have not yet been duplicated in non-human primate cells. Here, we introduce a multiplexed single-cell sequencing technique to profile the molecular features of monkey pluripotent stem cells in published culture conditions. The results demonstrate suboptimized maintenance of pluripotency and show that the selected signaling pathways for resetting human stem cells can also be interpreted for establishing monkey cell lines. Overall, this work legitimates the translation of novel human cell line culture conditions to monkey cells and provides guidance for exploring chemical cocktails for monkey stem cell line derivation.

RESUMEN

BACKGROUND@#The validation of various risk scores in elderly patients with comorbid atrial fibrillation (AF) and acute coronary syndrome (ACS) has not been reported. The present study compared the predictive performance of existing risk scores in these patients.@*METHODS@#A total of 1252 elderly patients with AF and ACS comorbidities (≥ 65 years old) were consecutively enrolled from January 2015 to December 2019. All patients were followed up for one year. The predictive performance of risk scores in predicting bleeding and thromboembolic events was calculated and compared.@*RESULTS@#During the 1-year follow-up, 183 (14.6%) patients had thromboembolic events, 198 (15.8%) patients had BARC class ≥ 2 bleeding events, and 61 (4.9%) patients had BARC class ≥ 3 bleeding events. For the BARC class ≥ 3 bleeding events, discrimination of the existing risk scores was low to moderate, PRECISE-DAPT (C-statistic: 0.638, 95% CI: 0.611-0.665), ATRIA (C-statistic: 0.615, 95% CI: 0.587-0.642), PARIS-MB (C-statistic: 0.612, 95% CI: 0.584-0.639), HAS-BLED (C-statistic: 0.597, 95% CI: 0.569-0.624) and CRUSADE (C-statistic: 0.595, 95% CI: 0.567-0.622). However, the calibration was good. PRECISE-DAPT showed a higher integrated discrimination improvement (IDI) than PARIS-MB, HAS-BLED, ATRIA, and CRUSADE (P < 0.05) and the best decision curve analysis (DCA). For thromboembolic events, the discrimination of GRACE (C-statistic: 0.636, 95% CI: 0.608-0.662) was higher than CHA2DS2-VASc (C-statistic: 0.612, 95% CI: 0.584-0.639), OPT-CAD (C-statistic: 0.602, 95% CI: 0.574-0.629) and PARIS-CTE (C-statistic: 0.595, 95% CI: 0.567-0.622). The calibration was good. Compared to OPT-CAD and PARIS-CTE, the IDI of the GRACE score slightly improved (P < 0.05). However, NRI analysis showed no significant difference. DCA showed that the clinical practicability of thromboembolic risk scores was similar.@*CONCLUSIONS@#The discrimination and calibration of existing risk scores in predicting 1-year thromboembolic and bleeding events were unsatisfactory in elderly patients with comorbid AF and ACS. PRECISE-DAPT showed higher IDI and DCA than other risk scores in predicting BARC class ≥ 3 bleeding events. The GRACE score showed a slight advantage in predicting thrombotic events.

RESUMEN

The main management principle for patients with coronary thrombus should be "more removal and less implantation". Routine thrombus aspiration (TA) is ineffective for intracoronary thrombus or high residual thrombus burden after TA and may result in a refractory coronary thrombus. It is unwise to implant a stent in the vessel with high residual thrombus, which is associated with no-reflow, impaired microvascular perfusion, and consequently worse clinical outcomes. Therefore, increasing the efficiency of TA during percutaneous coronary intervention procedures, especially under some conditions of refractory coronary thrombus, is very important to restore myocardial reperfusion and improve microvascular dysfunction early. In the present work, we aimed to demonstrate the factors that may affect TA efficiency and introduce several highly effective approaches to treat refractory coronary thrombus.

RESUMEN

OBJECTIVE@#To evaluate the correlation of magnetic resonance (MR) T2-weighted image (T2WI) signal characteristics of adenomyosis and the efficacy of high-intensity focused ultrasound (HIFU) ablation.@*METHODS@#Based on the presence or absence of patchy hyperintense foci on preoperative MR T2WI, the patients with adenomyosis undergoing HIFU treatment were divided into homogeneous signal group and heterogeneous signal group, and the heterogeneous group was further divided into heterogeneous hypointense group and heterogeneous isointense group according to signal intensity of the lesions. The patients in heterogeneous signal group were matched with the patients in the homogeneous group at a 1:1 ratio using the propensity score matching, and similarly, the patients in the heterogeneous hypointense group were matched with those in the heterogeneous isointense group at a 1:1 ratio. The non-perfused volume ratio (NPVR) and relief of dysmenorrhea were used to assess the therapeutic efficacy in the 4 groups.@*RESULTS@#A total of 299 patients were enrolled, who had a median preoperative dysmenorrhea score of 7.0 (6.0, 8.0) and a median NPVR of 53.5% (35.4, 70.1)%. After propensity score matching, the NPVR in homogeneous signal group was significantly higher than that in heterogeneous signal group [(60.3 ± 21.8)% vs (44.6±21.6)%, P < 0.05]. At 3, 6 and 12 months after HIFU, dysmenorrhea relief rates were higher in homogeneous signal group than in heterogeneous signal group, and the difference was statistically significant at 12 months (91.1% vs 76.8%, P < 0.05). The NPVR of heterogeneous hypointense group was higher than that of heterogeneous isointense group [(54.0±22.0) % vs (47.3± 22.9) %, P < 0.05]. At 6 months after HIFU, dysmenorrhea relief rate was significantly higher in heterogeneous hypointense group than in heterogeneous isointense group (91.5% vs 80.9%, P < 0.05).@*CONCLUSION@#The signal characteristics of adenomyosis on T2WI are closely related with the outcome of HIFU ablation, and its efficacy is better for homogeneous than for heterogeneous adenomyosis, and better for heterogeneous hypointense adenomyosis than for heterogeneous isointense adenomyosis.

RESUMEN

Occupational health literacy refers to the awareness and ability of workers to obtain basic knowledge of occupational health, practice healthy working styles and lifestyles, prevent the risk of occupational and work-related diseases, and maintain and promote their own health. In 2022, for the first time, China carried out nationwide monitoring for occupational health literacy of key populations. The National Institute for Occupational Health and Poison Control, Chinese Center for Disease Control and Prevention was responsible for technical support, formulating the National Technical Plan for Occupational Health Literacy Monitoring and Intervention of Key Populations, and formulating relevant requirements and specifications for monitoring purposes, monitoring scope and objects, sampling methods, monitoring content and methods, organization and implementation of field investigation, and quality control. In addition, the National Occupational Health Literacy Monitoring Questionnaire for Key Groups was provided, and the monitoring and intervention of occupational health literacy for key groups in the second- and third-key industries has been organized nationwide, so as to understand the occupational health literacy of the occupational population in China and provide important support for promotion of high-quality construction of healthy China.

RESUMEN

Objective:To investigate the correlation between serum remnant cholesterol(RC)and diabetic kidney disease(DKD)in elderly patients with type 2 diabetes mellitus(T2DM).Methods:The elderly patients with T2DM who were hospitalized in the Department of Geriatrics of the Second Xiangya Hospital of Central South University from January 2021 to March 2022 were selected and divided into simple diabetes group(410 cases)and DKD group(433 cases). The general clinical data and laboratory data were collected and the RC level was calculated.Spearman rank correlation was used to analyze the correlation between RC level and metabolic indicators.Logistic regression was used to analyze the correlation between serum RC level and the risk of DKD.Results:Compared with the simple diabetes group, patients in the DKD group had older age, longer duration of diabetes, higher levels of systolic blood pressure(SBP), fasting C-peptide, triglyceride(TG), uric acid(UA), serum creatinine, urinary albumin/creatinine ratio(UACR)and RC, and lower levels of albumin, high-density lipoprotein cholesterol(HDL-C)and estimated glomerular filtration rate(eGFR)( P<0.05 for all). Spearman rank correlation analysis showed that serum RC level was positively correlated with body mass index(BMI)( r=0.069, P=0.046), fasting blood glucose( r=0.099, P=0.004), glycosylated hemoglobin(HbA1c)( r=0.075, P=0.031), fasting C-peptide( r=0.177, P<0.001), TG( r=0.632, P<0.001), total cholesterol(TC)( r=0.306, P<0.001), low density lipoprotein cholesterol(LDL-C)( r=0.243, P<0.001), UA( r=0.128, P<0.001), serum creatinine( r=0.086, P=0.013)and UACR( r=0.147, P<0.001), and was negatively correlated with HDL-C( r=-0.271, P<0.001)and eGFR( r=-0.148, P<0.001). Logistic regression analysis showed that high serum RC level was a risk factor for DKD(Q1 as reference; Q2: OR=2.439, 95% CI: 0.836-7.113, P=0.103; Q3: OR=3.999, 95% CI: 1.187-13.478, P=0.025). Conclusions:High serum RC level is closely related to DKD in elderly patients with T2DM, and is a risk factor for DKD.

RESUMEN

Surgical intervention is the first choice treatment for intertrochanteric fractures that are common in clinical practice. Cephalomedullary nailing with two parts inserted respectively into the femoral medullary cavity and femoral head has been the mainstream protocols for the elderly patients with intertrochanteric fracture, but insertion of the cephalomedullary nail may likely lead to the outward displacement of the femoral shaft and the inversion and rotation of the head and neck bone mass, namely the so-called wedge effect. However, few reports have dealt with how to prevent the wedge effect and reduce the complications it may cause such as coxa vara deformity. The present review expounds and analyzes the concept, biomechanical mechanism, influencing factors, measurements, and prevention methods of the wedge effect, hoping to help the surgeons who try to avoid the wedge effect in surgical treatment.

RESUMEN

Objective:Compare the clinical efficacy and safety of bendamustine combined with rituximab (BR regimen) and rituximab combined with standard CHOP regimen (R-CHOP regimen) in the treatment of newly diagnosed follicular lymphoma (FL).Methods:Adopting a prospective case-control study method. 104 newly diagnosed FL patients admitted to Beijing Aerospace General Hospital from January 2018 to January 2022 were selected and randomly divided into an observation group and a control group using a random number table method, with 52 patients in each group. The observation group was treated with bendamustine combined with rituximab, while the control group was treated with rituximab combined with standard CHOP regimen. Both groups were treated for 6 consecutive courses of treatment, with a 21 day treatment period. Compare the serum lactate dehydrogenase (LDH) levels before and after treatment between two groups β 2-Microglobulin (β 2-microglobulin, β 2-MG level, improvement in quality of life after treatment, long-term survival, clinical efficacy, and incidence of adverse reactions. Measurement data is represented by paired t-tests for intra group comparisons, and independent sample t-tests for inter group comparisons; Counting data is represented as an example (%), and inter group comparisons are made using χ 2-test, Wilcoxon rank sum test was used for comparing rank data. Survival analysis was conducted using the Log Rank test. Results:After treatment, serum LDH and The levels of β 2-MG were lower than before treatment [LDH: (262.34±37.24) U/L ratio (323.45±44.46) U/L, (287.23±43.19) U/L ratio (318.28±52.35) U/L; β 2-MG: (2.72±0.30) mg/L compared to (3.45±0.37) mg/L, (2.93±0.28) mg/L compared to (3.37±0.42) mg/L, t-values of 7.60, 3.30, 11.05, 6.29, P values of <0.001, 0.001, <0.001, <0.001, <0.001], and the observation group was lower than the control group ( t-values of 3.15, 3.69, P values of 0.002, <0.001, respectively). After 6 courses of treatment, the quality of life in the observation group improved in 27 cases, stabilized in 22 cases, and decreased in 3 cases; The quality of life in the control group improved in 18 cases, stabilized in 26 cases, and decreased in 8 cases. The improvement of quality of life in the observation group was better than that in the control group ( Z=-2.03, P=0.042). The progression free survival period in the observation group was longer than that in the control group [52.53 months (95% confidence interval: 49.16-55.89 months) compared to 38.84 months (95% confidence interval: 32.44-45.24 months)], and the difference was statistically significant (Log Rank χ 2=4.06, P=0.044), there was no statistically significant difference in overall survival between the two groups ( P=0.217). The complete remission rate in the observation group was higher than that in the control group [88.46%(46/52) vs 71.15%(37/52)], χ 2=4.83, P=0.028], there was no statistically significant difference in objective response rates between the two groups ( P=0.485). The incidence of nausea, vomiting, leukopenia, neutropenia, alopecia, and fatigue in the observation group was lower than that in the control group, and the differences were statistically significant (all P<0.05). Conclusions:Both the BR regimen and R-CHOP regimen can significantly reduce serum tumor marker levels in the treatment of newly diagnosed FL. However, the BR regimen has a higher complete response rate, better patient quality of life, longer PFS, fewer toxic side effects, and more significant overall efficacy.
