ABSTRACT

Pyruvate dehydrogenase E1 component subunit beta-1 (PDHB-1) is a gene encoding the β-subunit of pyruvate dehydrogenase complex, which plays an important role in fruit acid accumulation. The aim of this study was to investigate the evolution characteristics of apple PDHB-1 family and its expression in apples with different acid contents. Bioinformatics analysis was performed using databases including NCBI, Pfam and software including ClustalX, MEGA, and TBtools. By combining titratable acid content determination and quantitative real-time PCR (qRT-PCR), the expression of this family genes in the peel and pulp of apple 'Asda' and 'Chengji No.1' with different acid content were obtained, respectively. The family members were mainly located in chloroplast, cytoplasm and mitochondria. α-helix and random coil were the main factors for the formation of secondary structure in this family. Tissue-specific expression profiles showed that the expression of most members were higher in fruit than in other tissues. qRT-PCR results showed that the expression profile of most members was consistent with the profile of titratable acid contents. In the peel, the expression levels of 14 members in 'Asda' apples with high acid content were significantly higher than that in 'Chengji No.1' apples with low acid content, where the expression difference of MdPDHB1-15 was the most significant. In the pulp, the expression levels of 17 members in 'Asda' apples were significantly higher than that in 'Chengji No.1' apples, where MdPDHB1-01 was the most highly expressed. It was predicted that PDHB-1 gene family in apple plays an important role in the regulation of fruit acidity.

ABSTRACT

AIM:To evaluate the agreement of corneal high-order aberrations from Topcon KR-1W, i.Profiler and OPD-Scan Ⅲ wavefront aberrometers in myopic adults.METHODS:A prospective clinical study. A total of 92 adult patients(92 eyes)with myopia in the department of optometry, the People's Hospital of Guangxi Zhuang Autonomous Region from June to August 2022 were enrolled. The third-order and fourth-order corneal aberrations at the pupil diameter of 4 and 6mm were measured by Topcon KR-1W, i.Profiler, and OPD-Scan Ⅲ, respectively. The difference and agreement of the three aberrometers were evaluated.RESULTS: The measurements at 6mm pupil diameter were all greater than those at 4mm pupil diameter. Although there were no statistical differences in the measurements of Z-44、Z-24 by the three aberrometers at 4 pupil diameter(P>0.05), there were statistical differences in other measurements(P<0.05). The aberration results measured by the three aberrometers were statistically different at the 6mm pupil diameter(P<0.05). The 95% limit of agreement(95%LoA)of the measurements of higher-order aberration, including the third-order aberrations at 4mm pupil diameter and the third-order and fourth-order aberrations at 6mm pupil diameter(except for the Z-24)were greater than 0.1μm. The concordance correlation coefficient(Pc)was lower than 0.90, indicating a poor consistency. The correlation coefficients of corneal higher-order aberrations were significantly different among the three aberrometers at 4 and 6mm pupil diameter(r4mm=0.215~0.805, P4mm<0.05; r6mm=0.561~0.916, P6mm<0.001).CONCLUSION:There were significant differences in the measurements of the third- and fourth-order corneal aberrations at 4 and 6mm pupil diameter among Topcon KR-1W, i.Profiler, and OPD-Scan Ⅲ, and the agreements were poor, so they are not interchangeably in clinical applications.

ABSTRACT

【Objective】 To evaluate the application of monoclonal typing reagents and human anti-A/B antibodies for absorption-elution test in ABO grouping. 【Methods】 The specificity of monoclonal typing reagents and human anti-A/B antibodies with standard A, B, O and AB phenotypes at 4 ℃, room temperature, and 37 ℃ were compared. Affinity was evaluated by the titer, agglutination time and agglutination intensity of the reaction with A1/B cells. 29 samples with ABO discrepancy were tested to evaluate the ability of monoclonal typing reagents and human anti-A/B antibodies to detect weak antigens in absorption-elution test. 【Results】 The specificity and affinity of human anti-A/B antibodies are low, and monoclonal typing reagents have cross reactivity. Human anti-A/B antibodies can detect most weak antigens in absorption-elution test with no cross reactivity. 【Conclusion】 In ABO grouping, the human anti A/B antibody binding absorption-elution test can serve as a supplement method for identifying ABO weak antigens. Accurate results can be obtained with reasonable reagents and corresponding methodology in serological tests,thus ensuring the safety of blood transfusion.

ABSTRACT

【Objective】 To establish a rare blood group information supply platform in Shaanxi Province. 【Methods】 The rare blood group information supply platform consists of sample registration, result registration, donor files and inventory blood. The blood donation codes of voluntary blood donors were recorded for blood typing, and the antigen identification results of each blood group system were registered, all stored in the rare blood type information supply platform. When receiving an application for unusual or rare blood type missing multiple conventional antigens or a certain high-frequency antigen, the corresponding antigen negative blood donors and their blood status (in stock or not) were queried from the donor profile module of the platform, and the inventory of blood of rare blood type was monitored dynamically. 【Results】 The results showed that 5.060% (273/5 398) of rare Rh phenotype donors, 1.540‰ (51/33 010) of donors lacking multiple regular antigens, and 13 O-type donors lacking high-frequency antigens were recorded in the rare blood type information supply platform. Among them, 0.019‰ (3/158 484) of Jk(a-b-) phenotype, 0.436‰ (2/4 586) of Di(a+b-) phenotype, and 4.030‰ (8/1 983) of Fy (a-b+) phenotype were stored in the blood bank for rare blood type. 【Conclusion】 The establishment of rare blood group information supply platform can meet the urgent demand for blood of rare blood types in clinical practice and ensure the safety of blood transfusion.

ABSTRACT

【Objective】 To observe the distribution of non-ABO-HDN and its clinical relevance, so as to provide reference for clinical diagnosis and treatment. 【Methods】 A total of 287 cases of non-ABO-HDN recorded during January 2012 to August 2022 were enrolled and tested in our laboratory. The correlation between maternal history of blood transfusion, pregnancy, unexpected antibody titers, gender, ABO-HDN and transfusion therapy was analyzed by chi-square test. 【Results】 All 287 cases of non-ABO-HDN involved 13 kinds of unexpected antibodies of 6 blood group systems. Rh-HDN accounted for 96.17% (276/287), and anti-D-HDN accounted for 47.04% (135/287). The proportion of non-ABO-HDN patients without ABO-HDN requiring exchange/transfusion was significantly higher than that of non-ABO-HDN patients with ABO-HDN(P8) was significantly higher than that in the low titer group (≤8) (P<0.05). There was no significant difference in gender, mother′s history of blood transfusion, pregnancy and whether or not to exchange/transfusion (severity of illness). 【Conclusion】 Understanding the characteristics of non-ABO-HDN and the specific distribution of unexpected antibodies, the correlation between various factors and diseases and their clinical significance are conductive to timely taking necessary intervention measures and reducing the risk of complications.

ABSTRACT

【Objective】 To observe the distribution of the unexpected antibodies in order to study the safety and strategies in 1 779 cases of clinical blood transfusion. 【Methods】 A total of 1 779 patients with unexpected antibodies were enrolled from transfusion candidates in various hospitals in Xi′an during a 10-year period(from 2012 to 2022.5). 【Results】 The unexpected antibodies were detected in 926(52.05%) of 1779 samples. The detected antibodies were mainly from 8 blood group systems and their distributions were as follows: Rh antibodies in 69.76%(646/926), Kidd in 2.59%(24/926), Lewis in 4.21%(39/926), MNS in 12.53%(116/926), P in 0.43%(4/926), Diego in 0.65%(6/926), Duffy in 0.54%(5/926), I in 0.97%(9/926), Rh+ MNS in 1.30%(12/926), Rh+ Lewis in 0.65%(6/926), Rh+ Kidd in 3.24%(30/926), Rh+ Diego in 1.51%(14/926), Rh+ Duffy in 0.86%(8/926), MNS+ Diego in 0.11%(1/926), Rh+ MNS+ Kidd in 0.22%(2/926), Rh+ Lewis+ Kidd in 0.22%(2/926), Rh+ Kidd+ P in 0.11%(1/926), Rh+ Kidd+ Diego in 0.11%(1/926). 【Conclusion】 According to the distribution of unexpected antibodies in Xi′an, antibodies from Rh system, were the most common ones.First, the production of unexpected antibodies can be effectively reduced by establishing Rh compatible blood transfusion. Secondly, antibody screen cells containing low-frequency antigens, such as Mur, Dia and Wra, should be reasonably selected to prevent missing detection of anti-low frequency antigen antibodies in Xi′an. Furthermore, the genotyping technology of rare blood group should be promoted and a rare blood group red blood cell bank be established to optimize the blood inventory and ensure the safety of blood transfusion.

ABSTRACT

Objective: To investigate the effect of bare-metal stent related technique on distal aortic dissection involving abdominal visceral segment. Methods: A retrospective analysis was performed on clinical data of 33 patients with distal aortic dissection involved abdominal visceral segment, who hospitalized in the Vascular Surgery Department of Shanghai Changhai Hospital from July 2012 to September 2019. The effect of the treatment was evaluated according to the clinical and preoperative, intraoperative and follow-up imaging data derived from (aorta computed tomography angiography (CTA) and digital subtraction angiography (DSA)) as well as the changes of the maximal diameter of the aorta and the thrombosis of the false lumen of the dissection. The criteria were as follows: the maximum diameter change of aortic dissection<5 mm was defined as stable; the maximum diameter decrease of aortic dissection≥5 mm was defined as effective reduction; the maximum diameter increase of aortic dissection≥5 mm was defined as expansion; the definition of diameter change of false lumen was the same as above. The hospital complications, clinical symptoms and survival were recorded. Results: There were 28 male patients in this cohort, the mean age was (57.6±4.9) years old. Twenty-one patients were treated with bare-metal stent and coils technique, of which 8 patients were jointly treated with stent grafts. Twelve patients were treated with multi-layer bare-metal stent technique, of which 4 patients were jointly treated with stent grafts. Intraoperative DSA image results showed that the visceral arteries were patent during the treatment, and the blood flow velocity of the false lumen was reduced in all 33 patients. There were no adverse events such as distal outflow tract embolism and coil displacement during the operation. During the period of hospitalization, one patient developed intimal rupture of subrenal abdominal aortic dissection on the fourth day after operation and emergency endovascular graft exclusion was performed for abdominal aortic dissection, and the patient recovered well from the emergency operation. The follow-up time was (16.7±14.0) months. One patient died 1 year after surgery due to non-disease-related factors. Follow-up CTA imaging results showed that the maximum diameter of the aorta in abdominal visceral segment tended to be smaller ((39.1±13.4) mm vs. (41.3±11.9) mm, P=0.469), and the maximum diameter of the false lumen was significantly reduced ((16.2±12.9) mm vs. (23.5±10.7) mm, P=0.014). The maximum diameter of the aortic dissection was reduced in 12 cases, stable in 19 cases, expanded in 2 cases. The maximum diameter of the false lumen was effectively reduced in 22 cases, stable in 10 cases, and expanded in 1 case. Four patients developed small endoleak in the false lumen, one of them was nearby the renal artery stent, and the remaining patients experienced complete thrombosis of the false lumen. Conclusions: Endovascular treatment of distal aortic dissection involving abdominal visceral segment with bare-metal stents related technique could promote the shrink and the thrombosis of the false lumen, and slow down the blood flow from the tear into the false lumen in the setting of patency of visceral arteries.

ABSTRACT

OBJECTIVE@#To follow up the participants of the randomized clinical trial "Efficacy and Safety of Niaoduqing Particles () for Delaying Moderate-to-Severe Renal Dysfunction", and assess the long-term effects of Niaoduqing Particles on delaying the progression of renal dysfunction.@*METHODS@#Participants, who had previously been randomly assigned to receive Niaoduqing Particles or placebo for 24 weeks (146 cases in each group), were invited to follow-up and all were administered Niaoduqing Particles 5 g thrice daily and 10 g before bedtime for 24 weeks. The primary endpoints were changes in baseline serum creatinine (Scr) and estimated glomerular filtration rate (eGFR) after completion of the open-label treatment period.@*RESULTS@#After the double-blind period, the median (interquartile range) changes in Scr were 1.1 (-13.0-24.1) and 11.7 (-2.6-42.9) μmol/L for the Niaoduqing Particle and placebo groups, respectively (P=0.008), and the median changes in eGFRs were-0.2 (-4.3-2.7) and-2.21 (-5.7-0.8) mL•min•1.73 m, respectively (P=0.016). There were significant differences in the double-blind period changes in renal function between groups. After the open-label period, the median changes in Scr were 9.0 (-10.0-41.9) and 17.5 (-6.0-50.0) μmol/L for the Niaoduqing Particle and placebo groups according to baseline grouping, respectively (P=0.214), and the median changes in eGFRs were-2.3 (-6.4-1.9) and-3.7 (-7.5-1.1) mL•min•1.73 m, respectively (P=0.134). There were no statistical differences in the open-label period changes in renal function between groups. The eGFR reduction of participants who accepted Niaoduqing Particle treatment for 48 weeks was projected to 2.5 mL•min•1.73 m per year.@*CONCLUSION@#Niaoduqing Particles appear to have long-term efficacy for patients with moderate-to-severe renal dysfunction. Although there was no statistical difference, the early use of Niaoduqing Paticles seems to ameliorate the worsening of renal function. (Trial registration No. ChiCTR-TRC-12002448).

ABSTRACT

Shenfu Injection (SFI) is a well-defined Chinese herbal formulation that is obtained from red ginseng and processed aconite root. The main active constituents in SFI are ginsenosides and aconitum alkaloids. In this work, ginsenosides (ginsenoside Rg1, ginsenoside Rb1 and ginsenoside Rc) and aconitum alkaloids (benzoylmesaconine and fuziline) were used as the index components to explore the pharmacokinetic behavior of SFI. A selective and sensitive HPLC-MS/MS method was developed for the quantification of ginsenosides and aconitum alkaloids in dog plasma and was used to characterize the pharmacokinetics of the five index components after intravenous drip of three different dosages of SFI in beagle dogs. The pharmacokinetic properties of the index components were linear over the dose range of 2-8 mL/kg.

ABSTRACT

OBJECTIVE@#To investigate the associations between chronic kidney disease (CKD) and body mass index (BMI), waist circumference(WC), waist-to-height ratio (WheiR) in Chinese adults.
@*METHODS@#A total of 26 655 participants, who voluntarily attended annual health examination at the Health Management Center in the Third Xiangya Hospital of Central South University from June 2013 to February 2014, were enrolled for this study. Logistic regression and receiver operating characteristic (ROC) curve analysis were performed.
@*RESULTS@#The prevalence rate of CKD was 9.6% and 3.1% in male and female subjects, respectively. Multivariate logistic regression analysis showed that BMI, WC and WheiR were independent risk factors for CKD in diabetic male and hypertensive male subjects (P<0.01). However, no association between these obesity indices and CKD was found in women after multivariate adjustment. In diabetic male subjects, when BMI≥28.7 kg/m(2), WC=90.7 cm and WheiR=0.56, the sensitivity and specificity prediction for CKD was 24.8%, 58.5%, 45.5% and 83.3%, 54.4%, 69.6%, respectively. In hypertensive male subjects, when the optimum cut-off points for BMI, WC and WheiR were ≥
27.0 kg/m(2), 91.2 cm and 0.54, the sensibility prediction for CKD were 41.0%, 47.0% and 50.1%, respectively, while the specificity prediction were 68.0%, 63.0% and 61.4%, respectively. The area under the ROC curve of BMI, WC, WheiR for CKD prediction were 0.56, 0.57, 0.59 in diabetic male subjects and 0.54, 0.56, 0.57 in hypertensive male subjects, respectively.
@*CONCLUSION@#BMI, WC and WheiR are associated with the increased risk for CKD in diabetic or hypertensive male subjects. However, the value for these obesity indices is limited in screening CKD.

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the clinical efficacy and safety of treatment of chronic primary glomerulopathy (CPG) patients of Shen deficiency and dampness heat syndrome (SDDHS) by Yishen Qingli Granule (YQG) combined with low-dose Tripterygium Wilfordii multiglycoside Tablet (TWT).</p><p><b>METHODS</b>Totally 231 CPG patients of SDDHS were enrolled in this study (including 60 patients from First Affiliated Hospital of Nanjing University of Chinese Medicine, 58 from First Affiliated Hospital of Nanjing Medical University, 46 from Xinqiao Hospital of Third Military Medical University, 35 from First Affiliated Hospital of Guangzhou University of Chinese Medicine, 14 from First Affiliated Hospital of Soochow University, and 18 from Wuxi Affiliated Hospital of Nanjing University of Chinese Medicine). They were randomly assigned to the control group (116 cases) and the trial group (115 cases) according to block group method. There were 217 cases in the safety analysis set (109 cases in the trial group vs 108 cases in the control group), and 203 cases in the full analysis set (99 cases in the trial group vs 104 cases in the control group). All patients received basic treatment such as ACEI/ARB. Furthermore, YQG (consisting of raw astragalus 10 g, prepared Polygonum Multiflorum 10 g, Pyrrosia 10 g, 1.5 g each package, containing 10 g of crude drugs) was additionally given to patients in the trial group, each package, twice daily. The TWT (10 mg) was given, twice a day. The TWT dose was adjusted according to 24 h urinary total protein (UTP). The placebos of YQG and TWT were administered to those in the control group. The treatment course consisted of 24 weeks and the follow-up visit lasted for 24 weeks. The biochemical indices were observed before and after treatment including 24 h UTP, urine red cell count (U(RBC)), renal functions (BUN, SCr), blood routine test (WBC), and liver functions (SGPT, SGOT). Reverse reactions such as gastrointestinal discomfort, skin rash, and irregular menstruation were also observed.</p><p><b>RESULTS</b>Compared with the control group, the total effective rate was better in the trial group (82.83% vs 61.54%, P < 0.01). Results of stratified comparison of UTP showed better efficacy in the trial group (0.8-3.0 g/24 h, P < 0.01). The UTP decline occurred in the trial group after 8 weeks of treatment, with stable action, showing statistical difference when compared with the control group (P < 0.01). In the trial group, U(RBC) level decreased after treatment but changed more significantly. But there was no statistical difference in the changes when compared with the control group (P > 0.05). After treatment, there were no statistical difference in safety indicators such as WBC, SGPT, and SGOT between the two groups after treatment (P > 0.05).</p><p><b>CONCLUSION</b>On the basis of basic treatment such as ACEI/ARB, application of YQG combined with low-dose TWT had better effect in controlling proteinuria of CPG patients, and could help stabilizing their conditions with less adverse reactions.</p>

ABSTRACT

Objective To explore the association between CRP and circadian variation of blood pressure in both hypertensive and normotensive old population.Methods The 82 patients with essential hypertension (EH) and 79 normotensive adults were enrolled in this study. Serum high sensitive CRP (hsCRP) level was tested by fluorescence immunoassay technology. The 24-hour ambulatory monitor of the level and variability of blood pressure was carried out. Multivariable linear regression models were run to adjust the age, gender, body mass index, blood sugar, blood fat,smoking history and baseline blood pressure for analyzing the association between hsCRP and circadian variation of blood pressure.Results ( 1 ) The variability of systolic blood pressure during daytime,nighttime and 24-h our periods were higher in EH group than in control group (P<0.01 or P<0. 05), the variabilities of diastolic blood pressure were also significantly higher than in control group (P<0. 05), the dipping ratios of nocturnal systolic, diastolic and mean artery pressure were all less than in contrast group (all P<0.05). (2) The hsCRP was obviously higher in EH group than in control group [(5.44± 1.78)mg/L vs. (3.03±0. 72) mg/L, P<0. 01]. (3) The hsCRP had positive associations with diastolic blood pressure variability during daytime (r= 0. 492, P<0. 001 ), nighttime (r=0.240, P=0.048), and 24-hour (r=0.271, P=0.030). The variability in diastolic blood pressure predic ted the level of hs CRP(r=0.660, R2=0.436, P<0.001). (4) In control group, no significant association was found between CRP and variation of blood pressure.Conclusions The BP variability and serum CRP in EH patients are obviously higher than in normotensive patients,however, the nocturnal BP dipping ratio is less than in normotensive patients. Furthermore, the level of serum hsCRP in EH patients is positively associated with the variation of blood pressure, especially for variation of diastolic blood pressure.

ABSTRACT

ObjectiveTo study the MR Imaging features of breast phyllodes tumor (PT),and to correlate it with pathological results.MethodClinical and MRI findings were retrospectively reviewed in twenty-seven women with 28 PTs lesions confirmed by surgical pathology.Statistical analyses were one-way ANOVA for size analysis,Fisher exact test for analysis of MR appearances and Spearman correlation to study the relationship between MRI findings and BI-RADS categories.Results( 1 ) The histologic findings were benign,borderline and malignant PTs in 14.3% (4/28),53.6% (15/28) and 32.1% (9/28) of lesions,respectively.(2) The mean maximum-diameter were (6.4 ± 3.9) cm,(5.7 ± 2.2) cm in borderline type and (4.8 ± 1.8)cm in benign type respectively.The results showed differences in lesion's size among the three type (F = 287.541,P =0.000),especially between malignant and benign type (P = 0.033 ).(3)Internal non-enhanced septations and silt-like changes on enhanced images,as well as time-signal curve on MRI correlated significantly with the histological grade ( P < 0.05 ).( 4 ) If the category BI-RADS ≥ 4a was considered to be a suspicious sign for malignant lesion,the diagnostic accuracy of MRI would be 96.4% (27/28),and the BI-RADS category of the MRI could reflect the PT's histological grade with a low correlation coefficient ( r = 0.382,P = 0.045 ).Conclusion The findings of PT on MRI have some characteristics,with tumor size and several MRI features correlating with the histological grade of breast PT.
