ABSTRACT

Objective:To investigate the level of serum lipoprotein a [Lp (a)] in patients with diffuse large B-cell lymphoma (DLBCL) and its clinical significance.Methods:A retrospective cohort study was performed. The clinical data of 87 patients with DLBCL who were treated at Changshu No.2 People's Hospital from January 2017 to June 2022 (the newly treated DLBCL group) were retrospectively analyzed, and 78 healthy physical examination subjects were selected as the control group. The level of Lp(a) in the two groups and the level of Lp(a) in DLBCL patients achieving different therapeutic effects after treatment were compared. The receiver operating characteristic (ROC) curve was used to analyze the efficacy of serum Lp(a) in predicting the therapeutic effect of DLBCL patients, and the area under the curve (AUC) was calculated to determine the optimal critical value. Based on the optimal critical value, patients with DLBCL were divided into low Lp(a) group and high Lp(a) group, and the clinicopathological characteristics of DLBCL patients with different Lp(a) levels were compared. Cox proportional hazards model was used to analyze the factors affecting the prognosis of DLBCL patients. Kaplan-Meier method was used to compare the relapse-free survival (RFS) and overall survival (OS) of DLBCL patients with different Lp(a) levels.Results:The level of Lp (a) in the newly treated DLBCL group was higher than that in the control group[ (0.24±0.09) g/L vs. (0.09±0.06) g/L], and the difference was statistically significant ( t = 3.61, P = 0.019). Among 87 patients, 54 achieved complete remission (CR), 23 achieved partial remission (PR), and 10 achieved progression of the disease (PD). The Lp (a) levels of patients achieving CR, PR, and PD were (0.09±0.09) g/L, (0.12±0.08) g/L, and (0.25±0.15) g/L, respectively. The Lp (a) levels in patients achieving CR and PR were lower than those in the newly treated DLBCL patients [(0.24±0.09) g/L], and the differences were statistically significant (all P < 0.05). There was no statistically significant difference in the Lp (a) levels between patients achieving PD and the newly treated DLBCL patients ( P > 0.05). The ROC curve results showed that the optimal critical value of serum Lp (a) in predicting the efficacy of DLBCL patients was 0.25 g/L, AUC was 0.776 (95% CI: 0.676-0.876, P < 0.05), and its sensitivity and specificity was 66.67%, 82.76%, respectively. According to the optimal critical value of Lp (a) (0.25 g/L), patients were divided into the low Lp (a) group (≤ 0.25 g/L) (57 cases) and the high Lp (a) group (>0.25 g/L) (30 cases). The proportion of patients with lactate dehydrogenase level >227 U/L, Ann Arbor stage Ⅲ-Ⅳ, and extranodal organ involvement >1 in the high Lp (a) group was higher than that in the low Lp (a) group, and the differences were statistically significant (all P < 0.05). Cox multivariate analysis results showed that Ann Arbor stage Ⅲ-Ⅳ, international prognostic index (IPI) score 3-5, and Lp (a)>0.25 g/L were independent risk factors for OS in DLBCL patients (all P < 0.05); Ann Arbor stage Ⅲ-Ⅳ and IPI score 3-5 were independent risk factors for RFS in DLBCL patients (all P < 0.05). The median OS in the low Lp (a) group was not reached; the median OS of the high Lp (a) group was 21 months, and there was a statistically significant difference in OS between the two groups ( P = 0.001). The median RFS time was not reached in the low Lp (a) group and the high Lp (a) group; and there was no statistically significant difference in RFS between the two groups ( P = 0.102) . Conclusions:Lp(a) level of DLBCL patients is increased, and Lp(a) could be a factor influencing the prognosis of DLBCL.

ABSTRACT

Objective:To explore the application value of renal artery resistance index in the diagnosist of intra-abdominal hypertension (IAH) in critically ill patients.Methods:89 patients with risk factors of IAH in the intensive care unit of Zhangzhou Hospital Affiliated to Fujian Medical University from February 2022 to June 2022 were retrospective analyzed. The intra-abdominal pressure (IAP) were measured by bladder, and patients divided into IAH group (IAP≥12 mmHg) and non-IAH group (IAP <12 mmHg). The resistance index (RI) of the right renal aorta, segment artery and interlobar artery were measured by color Doppler ultrasound. The difference between the measurement indicators of patients in the IAH and non-IAH groups and the correlation with IAP were analyzed. As for different indicators to predict the diagnostic efficacy of IAH, ROC curve analysis was used to evaluate the effect. And further multivariate logistic regression analysis was to find independent risk predictor.Results:A total of 89 patients were included in the study, including 44 patients with normal IAP and 45 patients diagnosed IAH. There were significant differences in the right renal aorta, segmental artery and interlobar artery RI (all P<0.01). The interlobar artery RI≥0.698 was the highest diagnostic cut-off,area under the curve was 0.914, sensitivity was 82.2%, specificity was 97.7%, and Jordon index was 0.799. The Spearman correlation analysis of IAP and the ultrasonographic measurements revealed a strong correlation between right renal interlobar artery RI and IAP ( r=0.741, P<0.01). The multivariate logistic regression analysis showed that the right renal interlobar artery RI ( OR= 24.472, 95% CI:5.122~116.919, P<0.01) was an independent risk predictor of IAH ( P<0.01). Conclusion:Right renal interlobar artery RI had better diagnostic efficacy of IAH,renal ultrasound could be used as an alternative, non-invasive technique for the diagnosis and follow-up of IAH.

ABSTRACT

BACKGROUND:There are few studies on the effect of degeneration of paraspinal muscle on osteoporotic vertebral compression refractures treated by percutaneous vertebroplasty in postmenopausal women.This paper intends to reveal the relationship between them. OBJECTIVE:To investigate the relationship between degeneration of paraspinal muscle and osteoporotic vertebral compression refractures in postmenopausal women treated by percutaneous vertebroplasty. METHODS:The medical records of 81 postmenopausal female patients who were admitted to the First Affiliated Hospital of Guangzhou University of Chinese Medicine from May 2018 to March 2021 for osteoporotic vertebral compression fracture and received percutaneous vertebroplasty were retrospectively analyzed.The patients were divided into an osteoporotic vertebral compression refracture group(n=39)and a control group(n=42)according to whether they had osteoporotic vertebral compression refracture after percutaneous vertebroplasty.General data,vertebral bone mineral density,paravertebral cross-sectional area and mean CT value(Hu)of the two groups were analyzed. RESULTS AND CONCLUSION:(1)Univariate analysis showed that there was no significant difference in age and mean CT value of psoas major between the two groups(P>0.05).The body mass index,vertebral bone mineral density,paravertebral cross-sectional area and the mean CT value of the posterior vertebral muscle group in the control group were significantly higher than those in the osteoporotic vertebral compression refracture group(P<0.05).(2)Multivariate logistic regression analysis showed that low vertebral bone mineral density(OR=0.004,95%CI:0.000-0.555,P<0.05)and low mean CT value of posterior vertebral muscle group(OR=0.940,95%CI:0.894-0.988,P<0.05)were independent risk factors for postmenopausal osteoporotic vertebral compression refracture.(3)It is indicated that degeneration of paraspinal muscle will increase the risk of osteoporotic vertebral compression refractures in patients treated by percutaneous vertebroplasty,especially in postmenopausal women with a low mean CT value of low posterior vertebral muscle group.

ABSTRACT

Objective:To establish a sensing technology of catalytic hairpin self-assembly (CHA) combining with clustered interspaced short palindromic repeats with associated protein 12a (CRISPR-Cas12a) for the detection of exosomal microRNA-21 (miR-21), and to analyze the performance.Methods:Eight patients diagnosed as breast cancer in the First Affiliated Hospital of the Army Military Medical University from September to October 2023 were selected as the breast cancer group; 8 healthy individuals who underwent physical examinations during the same period were selected as the healthy control group. Plasma exosomes and their miR-21 were extracted using the kit. DNA hairpins and CRISPR RNA sequences were designed for miR-21 sequences. The feasibility of detection technology was validated using polyacrylamide gel electrophoresis and fluorescence spectrophotometer. Hairpins concentration, CHA reaction time, Cas12a protein concentration and Cas12a protein reaction time were further optimized. On this basis, miR-21 was detected at different concentrations (0, 0.1, 0.5, 1.0, 2.5, 5.0, 7.5, 10.0 nmol/L), and fluorescence intensity was collected for unary linear regression analysis to evaluate methodological sensitivity; meanwhile, different types of miRNAs (miR-31, miR-26a, miR-192, miR-25-3p) and blank controls were detected to evaluate methodological specificity. A case-control study was conducted to detect the relative expression level of plasma exosomal miR-21 in breast cancer group and healthy control group using this detection technology and reverse transcription PCR (RT-PCR) to evaluate the detection ability of clinical samples.Results:A detection method for exosomal miR-21 was established using CHA combining with CRISPR-Cas12a. The concentration of miR-21 detected by this method showed a good linear relationship with fluorescence intensity (the linear correlation coefficient 0.966 7), and the linear detection range was 0.1-10.0 nmol/L, and the detection limit was 87.81 pmol/L. The fluorescence intensity of miR-21 was 450.27±23.96 which was higher than that of miR-31, miR-26a, miR-192, miR-25-3p, and the blank group (98.89±7.35, 98.12±2.07, 98.93±2.45, 96.66±2.45, 82.93±3.54, respectively), with statistical significance ( P<0.001). The results of RT-PCR showed that the relative expression levels of plasma exosomal miR-21 in the breast cancer group were higher than that in healthy control group (1.83±0.27 vs 0.93±0.12, P<0.001); CHA combining with CRISPR-Cas12a detection technology showed that the relative expression levels of plasma exosomal miR-21 in breast cancer group were higher than that in healthy control group (1.94±0.21 vs 0.98±0.08, P<0.001); There was no significant difference in the relative expression levels of plasma exosomal miR-21 between CHA combining with CRISPR-Cas12a detection technology and reverse transcription PCR in breast cancer group and healthy control group ( P>0.05). Conclusion:In this study, a highly sensitive and specific sensing technology of CHA combining with CRISPR-Cas12a for exosomal miR-21 was established. The results of detecting plasma exosomal miR-21 were consistent with the results of reverse transcription PCR, which can be used for screening of breast cancer patients.

ABSTRACT

Aim To investigate the effect of quercetin on the aging model of bone marrow mesenchymal stem cells established under microgravity. Methods Using 3D gyroscope, a aging model of bone marrow mesenchymal stem cells was constructed, and after receiving quercetin and microgravity treatment, the anti-aging effect of the quercetin was evaluated by detecting related proteins and oxidation indexes. Results Compared to the control group, the expressions of age-related proteins p21, pi6, p53 and RB in the microgravity group significantly increased, while the expressions of cyclin D1 and lamin B1 significantly decreased, with statistical significance (P<0.05). In the microgravity group, mitochondrial membrane potential significantly decreased (P<0.05), ROS accumulation significantly increased (P <0.05), SOD content significantly decreased and MDA content significantly increased (P<0.05). Compared to the microgravity group, the expressions of age-related proteins p21, pi6, p53 and RB in the quercetin group significantly decreased, while the expressions of cyclin D1 and lamin B1 significantly increased, with statistical significance (P<0.05). In the quercetin group, mitochondrial membrane potential significantly increased (P<0.05), ROS accumulation significantly decreased (P<0.05), SOD content significantly increased and MDA content significantly decreased (P<0.05). Conclusions Quercetin can resist oxidation, protect mitochondrial function and normal cell cycle, thus delaying the aging of bone marrow mesenchymal stem cells induced by microgravity.

ABSTRACT

OBJECTIVE@#To investigate the effectiveness of comprehensive rhinoplasty with autogenous costal cartilage grafting and prosthesis augmentation rhinoplasty in the treatment of secondary nasal deformity with saddle nasal deformity after cleft lip surgery.@*METHODS@#The clinical data of 96 patients with secondary nasal deformity with saddle nasal deformity after cleft lip surgery between September 2008 and January 2019 were retrospectively analyzed. There were 17 males and 79 females with an average age of 25.6 years (range, 17-38 years). Autogenous costal cartilage grafts were used to construct stable nasal tip framework and enhance the strength of alar cartilage. Nasal dorsum prostheses (39 cases of bulge, 45 cases of silicone prosthesis) or autogenous costal cartilage (12 cases) were used for comprehensive rhinoplasty. Visual analogue scale (VAS) score was used to evaluate the postoperative satisfaction subjectively, and nasal alar height symmetry index, nasal alar width symmetry index, nasal dorsum central axis deviation angle, and nasal columella deviation angle were calculated to evaluate objectively before and after operation.@*RESULTS@#All patients were followed up 6 months to 8 years, with an average of 13.4 months. Nasal septal hematoma occurred in 3 patients after operation, which was improved after local aspiration and nasal pressure packing. Two cases had mild deformation of the rib cartilage graft of the nasal dorsum, one of which had no obvious deviation of the nasal dorsum and was not given special treatment, and one case underwent the cartilage graft of the nasal dorsum removed and replaced with silicone prosthesis. The incisions of the other patients healed by first intention, and there was no complication such as postoperative infection and prosthesis displacement. The nasal alar height symmetry index, nasal alar width symmetry index, nasal dorsum central axis deviation angle, and nasal columella deviation angle significantly improved after operation when compared with preoperative ones ( P<0.05). Postoperative subjective satisfaction evaluation reached the level of basic satisfaction or above, and most of them were very satisfied.@*CONCLUSION@#Comprehensive rhinoplasty using autologous rib cartilage grafting to construct a stable nasal tip support, combined with dorsal nasal prosthesis or autologous cartilage implantation, can achieve good effectiveness on secondary nasal deformity with saddle nasal deformity after cleft lip surgery.

ABSTRACT

Objective@#To construct a prognostic model for unsuccessful removal of nasogastric tube (NGT) was the aim of our study. @*Methods@#This study examined patients with swallowing disorders receiving NGT feeding due to stroke or traumatic brain injury in a regional hospital. Clinical data was collected, such as age, sex, body mass index (BMI), level of activities of daily living (ADLs) dependence. Additionally, gather information regarding the enhancement in Functional Oral Intake Scale (FOIS) levels and the increase in food types according to the International Dysphagia Diet Standardization Initiative (IDDSI) after one month of swallowing training. A stepwise logistic regression analysis model was employed to predict NGT removal failure using these parameters. @*Results@#Out of 203 patients, 53 patients (26.1%) had experienced a failed removal of NGT after six months of follow-up. The strongest predictors for failed removal were age over 60 years, underweight BMI, total dependence in ADLs, and ischemic stroke. The admission prediction model categorized patients into high, moderate, and low-risk groups for removal failure. The failure rate of NGT removal was high not only in the high-risk group but also in the moderate-risk groups when there was no improvement in FOIS levels and IDDSI food types. @*Conclusion@#Our predictive model categorizes patients with brain insults into risk groups for swallowing disorders, enabling advanced interventions such as percutaneous endoscopic gastrostomy for high-risk patients struggling with NGT removal, while follow-up assessments using FOIS and IDDSI aid in guiding rehabilitation decisions for those at moderate risk.

ABSTRACT

Background@#and Purpose Migraine is a condition that is often observed to run in families, but its complex genetic background remains unclear. This study aimed to identify the genetic factors influencing migraines and their potential association with the family medical history. @*Methods@#We performed a comprehensive genome-wide association study of a cohort of 1,561 outpatients with migraine and 473 individuals without migraine in Taiwan, including Han Chinese individuals with or without a family history of migraine. By analyzing the detailed headache history of the patients and their relatives we aimed to isolate potential genetic markers associated with migraine while considering factors such as sex, episodic vs. chronic migraine, and the presence of aura. @*Results@#We revealed novel genetic risk loci, including rs2287637 in DEAD-Box helicase 1 and long intergenic non-protein coding RNA 1804 and rs12055943 in engulfment and cell motility 1, that were correlated with the family history of migraine. We also found a genetic location downstream of mesoderm posterior BHLH transcription factor 2 associated with episodic migraine, whereas loci within the ubiquitin-specific peptidase 26 exonic region, dual specificity phosphatase 9 and pregnancy-upregulated non-ubiquitous CaM kinase intergenic regions, and poly (ADP-ribose) polymerase 1 and STUM were linked to chronic migraine. We additionally identified genetic regionsassociated with the presence or absence of aura. A locus between LINC02561 and urocortin 3 was predominantly observed in female patients. Moreover, three different single-nucleotide polymorphisms were associated with the family history of migraine in the control group. @*Conclusions@#This study has identified new genetic locations associated with migraine and its family history in a Han Chinese population, reinforcing the genetic background of migraine. The findings point to potential candidate genes that should be investigated further.
