Objective To explore the changes in serum energy metabolites in patients with peripheral T-cell lymphoma,and investigate serum biomarkers for monitoring peripheral T-cell lymphoma from the perspective of energy metabolism.Methods Multiple/selected reaction monitoring(MRM/SRM)was used to detect the energy-related metabolites in the sera of 16 patients with newly diagnosed peripheral T-cell lymphoma admitted in the Hematology Medical Center of the Second Affiliated Hospital of Army Medical University from November 2020 to December 2021,as well as 10 recruited healthy volunteers.The corresponding clinical data including medical history,laboratory results and image data were collected and retrospectively analyzed.Results Significant differences were seen in the contents and expression profiles of serum energy metabolism-related products between the patients and the healthy volunteers.The patients had significantly reduced serum contents of cyclic AMP,succinate,citrate and cis-aconitate(P＜0.05),and elevated D-glucose 6-phosphate content(P＜0.05).The serum contents of citrate and succinate were negatively correlated with the risk stratification(low-,moderate-and high-risk)and clinical stage of the disease(P＜0.05).Meanwhile,there was a negative correlation between the contents of L-malic acid and citrate and the mid-term efficacy evaluation results,such as complete/partial response(CR/PR)or stable disease(SD)(P＜0.05).For patients with extranodal NK/T cell lymphoma(n=10),there were also significant reductions in the contents of cyclic AMP,succinate,citrate,isocitrate and cis-aconitate in the sera of patients compared with healthy volunteers(P＜0.05),and the contents of citrate and succinate were negatively correlated with the clinical stage(P＜0.05)and were rather correlated with mid-term efficacy evaluation results(CR/PR or SD)(P＜0.05).For patients with angioimmunoblastic T-cell lymphoma(n=6),the serum contents of cyclic AMP,citrate and succinate were significantly lower,while the content of D-glucose 6-phosphate was higher when compared with the healthy volunteers(P＜0.05),and the content of succinate was negatively correlated with both clinical stage and risk grade of the patients(P＜0.05).Conclusion There are 5 serum differential metabolites identified between patients with peripheral T-cell lymphoma and healthy controls,and succinate and citrate are expected to be serum biomarkers of peripheral T-cell lymphoma.

BACKGROUND:The study of the lumbar spine and pelvis in patients with Lenke type 5 lordosis is limited to the coronal and sagittal planes,and the three-dimensional relationship between the scoliosis and the pelvis has not yet been clarified. OBJECTIVE:To analyze the effect of lumbar scoliosis on the pelvis in patients with Lenke type 5 lordosis and to study the correlation between the lumbar spine and the three-dimensional spatial position of the pelvis. METHODS:Imaging data of 60 patients with Lenke type 5 lordosis scoliosis admitted to the 3D Printing Reception Center of Shanghai Ninth People's Hospital,Shanghai Jiao Tong University School of Medicine from January 2019 to September 2023 were retrospectively analyzed,including Cobb angle,coronal pelvic tilt,lumbar lordosis,left and right pelvic hip width ratio(sacroiliac-anterior superior iliac spine),spinal rotation angle,pelvic tilt,sacral slope,pelvic incidence,coronal deformity angular ratio,sagittal deformity angular ratio,C7 plumb line-center sacral vertical line,apical vertebral translation,and coronal sacral inclination.The information was summarized as a database.SPSS 22.0 software was used to analyze the data related to the lumbar spine and pelvis of the patients with Lenke type 5 primary lumbar curvature adolescent idiopathic scoliosis using Spearman's correlation analysis and linear regression. RESULTS AND CONCLUSION:(1)Cobb angle was highly positively correlated with coronal deformity angular ratio,apical vertebral translation,and spinal rotation angle(r=0.91,r=0.841,r=0.736).(2)Coronal deformity angular ratio was highly positively correlated with apical vertebral translation(r=0.737),moderately positively correlated with C7 plumb line-center sacral vertical line(r=0.514),and moderately negatively correlated with sagittal deformity angular ratio(r=-0.595).(3)There was a high positive correlation between lumbar lordosis and sagittal deformity angular ratio(r=0.942)and a moderate negative correlation with coronal deformity angular ratio(r=-0.554).(4)There was a moderate positive correlation between Cobb angle with coronal pelvic tilt and coronal sacral inclination(r=0.522,r=0.534)and a moderate positive correlation between C7 plumb line-center sacral vertical line and coronal pelvic tilt(r=0.507).Apical vertebral translation with coronal pelvic tilt and coronal sacral inclination showed a moderate positive correlation(r=0.507,r=0.506).Lumbar lordosis with sacral slope and pelvic incidence showed a moderate positive correlation(r=0.512,r=0.538).Sagittal deformity angular ratio was moderately positively correlated with sacral slope and pelvic incidence(r=0.614,r=0.621).(5)Studies have found that the relative position of the lumbar spine and the pelvis is closely related in the horizontal,sagittal and coronal planes.When the lumbar spine affects scoliosis and is rotated,the relative position of the pelvis will also change to compensate,which indicates that while correcting scoliosis,the correction of the pelvis cannot be ignored.

As population aging progresses,musculoskeletal health will serve as one of the most important indicators of health status in older adults.Studies related to the promotion of vitamin D absorption by drugs are now more common,but the drugs are accompanied by subsequent side effects.Notably,several non-pharmacological therapies are also being investigated for their respective effects on promoting vitamin D absorption.The purpose of this paper is to analyze the mechanism of vitamin D in osteoporosis,and to discuss the progress of research on the promotion of vitamin D absorption by acupuncture,tui na and acupuncture point burial,as well as by sunlight,diet,aerobic exercise,tai chi and aerobics,in order to provide a reference for clinical and scientific research on the selection of appropriate methods to promote vitamin D absorption.At the same time,it provides a non-pharmacological way to control bone loss for people with long-term home bone loss and osteoporosis.

Lymphomas are a highly heterogeneous group of tumors that are classified into several subtypes. The gold standard method for the molecular profiling of lymphoma is based on invasive lymph node or tissue biopsy. However, this method cannot accurately capture spatial tumor heterogeneity in each patient as well as systemic tumor invasion and tumor burden. Circulating tumor DNA (ctDNA) is an emerging and highly versatile biomarker that overcomes the basic limitations of imaging scanning and tissue biopsy; has the characteristics of being simple, rapid, and non-invasive; and has good specificity and high sensitivity. ctDNA testing has been applied to a variety of subtypes of lymphoma and has been used for somatic mutation genotyping, efficacy monitoring during treatment, detection of minimal residual disease, and the prediction of survival, which may help clinicians make better clinical decisions in the diagnosis and treatment of lymphoma patients. Furthermore, this study also aims to review the different methods of ctDNA analysis and describe the specific applications of ctDNA in different lymphoma subtypes.

Objective:To compare the effect and safety of continuous veno-venous hemofiltration (CVVH)+double plasma molecular absorption (DPMA)+hemoperfusion (HP), CVVH+HP, and CVVH+plasma exchange (PE) in treatment of patient with severe wasp stings injury.Methods:Multicenter, historical cohort study and superiority test were used. From July 2020 to October 2022, patients with wasp sting injury and multiple organ damage admitted to the intensive care units (ICU) of five hospitals were consecutively screened and recruited into the CVVH+DPMA+HP group (intervention group). Propensity score matching was used to establish historical cohorts. Patients with severe wasp sting injury who hospitalized from January 2016 to June 2020 in each ICU were collected and matched 1∶1 with the intervention group, and divided into CVVH+HP group and CVVH+PE group according to their actual hemopurification protocols (historical control groups). The primary outcome was the acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score on days 3 and 7 after initiation of treatment. Secondary outcomes included complications, length of ICU and hospital stays, and all-cause mortality. Multivariate Cox proportional risk regression was used to analyze the prognosis of patients.Results:After propensity score matching, 56 patients in intervention group and each of the two historical control groups were matched successfully. There were no significant differences in age, gender, comorbidities, biochemical test indices and critical illness scores among the groups. After treatment, APACHE Ⅱ score markedly declined in all groups, and the decrease was faster in the intervention group; treatment with DPMA [hazard ratio ( HR) = 1.04, 95% confidence interval (95% CI) was 1.02-1.08, P = 0.00], the decreased levels of body temperature ( HR = 1.02, 95% CI was 1.00-1.03, P = 0.02), serum creatine kinase (CK; HR = 0.98, 95% CI was 0.96-1.00, P = 0.05) and myoglobin (MYO; HR = 2.88, 95% CI was 1.24-6.69, P = 0.01) were independent risk factors for APACHE Ⅱ score decline to the target value (15 scores). There were no significant differences in the incidence of bleeding complications, filter or perfusion thrombosis, blood pressure reduction, catheter-related infection and anaphylaxis among the groups. Conclusion:CVVH+DPMA+HP regimen can significantly reduce the APACHE Ⅱ score of patients with severe wasp sting injury, and the efficacy is superior to CVVH+HP and CVVH+PE regimens, with safety.

ObjectiveTo investigate the in-brace and short-term correction of 3D-printed scoliosis orthoses. MethodsFrom July to December 2021, 36 patients with adolescent idiopathic scoliosis from Ninth People's Hospital, Shanghai Jiaotong University School of Medicine were selected to complete full-length radiographs of the spine before and immediately after wearing the orthosis. They wore the orthosis more than 20 hours a day, and took radiographs six months later. Cobb angle was calculated. They were assessed with Chinese version of the Scoliosis Research Society's outcomes instrument 22 (SRS-22) before wearing and six months follow-up. ResultsThe mean Cobb angle was (22.10±6.29)° before wearing, and it was (7.85±10.90)° immediately after wearing (t = 4.775, P < 0.01) and (14.33±0.74)° six months follow-up (t = 4.189, P < 0.01). The score of functional status of SRS-22 increased six months follow-up (Z = -2.676, P < 0.01). The Cobb angle immediately after wearing correlated with the Cobb angle six months follow-up (r = 0.826, P < 0.05). Conclusion3D-printed scoliosis orthoses can correct the scoliosis satisfactorily, in-brace and in short-term.

Objective To analyze the effect of body mass index (BMI) on pulmonary function and quality of life in elderly patients with chronic obstructive pulmonary disease (COPD), and to provide theoretical basis for the diagnosis and treatment of COPD. Methods A total of 1 278 patients who visited the respiratory department of our hospital from January 2019 to June 2022 were selected as the research objects, including 368 COPD patients, 225 of whom were in stable stage and 143 of whom were in acute exacerbation stage. According to BMI, they were divided into low group (n=31, BMI<18.5kg/m²), normal group (n=198,18.5kg/m2≤BMI<24 kg/m²), overweight group (n=106, 24kg/m²≤BMI<28 kg/m²) and obese group (n=33,BMI≥28 kg/m²). Health-related quality of life (HRQOL) was used to evaluate the quality of life of patients. Forced expiratory volume in one second (FEV1), forced vital capacity (FVC) and FEV1/FVC were measured by pulmonary function instrument to evaluate the pulmonary function grade of patients. Logistic regression was used to analyze the risk factors of pulmonary function and quality of life in COPD patients. Results There were significant differences in age, smoking, BMI and hyperlipidemia between stable COPD patients and acute exacerbation COPD patients with different BMI groups (P<0.05). There were significant differences in the proportion of pulmonary function Ⅲ/Ⅳ, FEV1/FVC, FEV1pred and HRQOL scores among different BMI groups (P<0.05) . The FEV1/FVC and FEV1pred in patients with acute exacerbation and stable COPD from high to low were obese group, overrecombination group, normal group and too low group, and the differences were statistically significant (P<0.05). The HRQOL scores of COPD patients in acute exacerbation and stable stage from high to low were obese group, overweight group, normal group and too low group, and the difference was statistically significant (P<0.05). Low body mass index was a risk factor for pulmonary function in COPD patients at stable stage (OR=2.52) and acute exacerbation stage (OR=2.83) (P<0.05). High body mass index was a risk factor for quality of life in patients with stable COPD (OR=2.43) and acute exacerbation (OR=2.65) (P<0.05). Conclusion BMI can affect pulmonary function and quality of life in COPD patients. Patients should maintain normal BMI, which can improve pulmonary function and quality of life.

Objective The purpose of this study was to examine effects of Isopsoralen on the osteoblast proliferation and differentiation and find its possible molecular mechanisms for anti-osteoporosis.Methods OCT-1 cells were cultured with common methods.While growing well,cells were cultured with 3 doses(10 μg·mL-1,30u μg·mL-1 and 60 μg·mL-1)of Isopsoralen for 48 h,or with purified bone morphogenetic protein 2(BMP2)protein(50 ng·mL-1).We first determined the effect of Isopsoralen on cell proliferation by MTT assay.The real time RT-PCR was also used to quantify changes in the mRNA levels of several genes,such as BMP2,Runt-related transcription factor 2(Runx2),and Osterix(Osx).We also used the Western blot analysis to evaluate the expression of Runx2 and Osx proteins.At last we used the BMP2loxp/loxp mice to isolate the primary calvaria osteoblasts,cultured with Isopsoralen of the best dose for 48 h after the in vitro conditional gene knockout technology,and tested the gene expressions of Runx2 and Osx.And the alkaline Phosphatase(ALP)staining was also performed.Result Isopsoralen(10 μg·mL-1)can promote osteoblast proliferation obviously.From the real time RT-PCR analysis,Isopsoralen can enhance the BMP2 mRNA levels,the effect of 10 μg·mL-1 was the best,and 30 μg·mL-1 followed.In addition,we found that Isopsoralen(10 μg·mL-1)can enhance the Runx2 mRNA levels significantly.We also found that lower doses of Isopsoralen can enhance the Osx mRNA levels,the effect of 30 μg·mL-1 was the best,and 10 μg·mL-1 followed.From the Western blot analysis,low doses of Isopsoralen(10 μg·mL-1 and 30 μg·mL-1)can stimulate the expression of Runx2 protein.Besides,three doses of Isopsoralen can stimulate the expression of Osx protein,and the effect of 10 μg·mL-1 and 30 μg·mL-1 are better.Finally,the results of in vitro conditional gene knockout experiment showed that the overexpression of Runx2 and Osx genes in osteoblasts,as well as ALP staining,induced by Isopsoralen are BMP2 dependent.Conclusions In this study,we firstly demonstrate that Isopsoralen can stimulate osteoblast proliferation and differentiation by mediating BMP2/Runx2/Osx signaling pathway.

Objective To study the pain prevalence and clinical characteristics in Parkinson disease (PD) for better understanding its pathophysiology and improving nursing care and treatment. Methods A cross-sectional controlled study was conducted at Department of Neurology, West China Hospital of Sichuan University from November 2015 to November 2016. A total of 316 subjects with mini-mental state examination scores ≥ 24 were enrolled, including 162 PD patients and 154 controls. Pain was assessed using the medical outcomes study 36-item short-form health survey (SF-36v2) bodily pain scale, and a body illustration including 45 anatomical areas for subjects to indicate the prevalence, severity and location of pain. Results Pain prevalence and severity in the PD group were significantly higher than those in the control group (P<0.001). Pain distribution was similar between groups, predominantly in the lower back, followed by the gluteal region, lower legs, thighs, posterior neck, and shoulders, but the prevalence of pain location in each between groups was with statistical significance (all P<0.05). Conclusions Pain prevalence in the PD group is significantly higher than that of normal people as well as its severity, but both groups are not similar in pain location. Pain is a significant problem in daily life of PD patients. Recognition of this has the potential to aid the better clinical management of and improved quality of life for PD patients.
