ABSTRACT

Objective: Compare and analyze the results of the domestic Lanyi AH600 glycated hemoglobin analyzer and other different detection systems to understand the comparability of the detection results of different detectors, and establish the best cut point of Lanyi AH600 determination of haemoglobin A1c (HbA1c) in the diagnosis of diabetes. Methods: Multi center cohort study was adopted. The clinical laboratory departments of 18 medical institutions independently collected test samples from their respective hospitals from March to April 2022, and independently completed comparative analysis of the evaluated instrument (Lanyi AH600) and the reference instrument HbA1c. The reference instruments include four different brands of glycosylated hemoglobin meters, including Arkray, Bio-Rad, DOSOH, and Huizhong. Scatter plot was used to calculate the correlation between the results of different detection systems, and the regression equation was calculated. The consistency analysis between the results of different detection systems was evaluated by Bland Altman method. Consistency judgment principles: (1) When the 95% limits of agreement (95% LoA) of the measurement difference was within 0.4% HbA1c and the measurement score was≥80 points, the comparison consistency was good; (2) When the measurement difference of 95% LoA exceeded 0.4% HbA1c, and the measurement score was≥80 points, the comparison consistency was relatively good; (3) The measurement score was less than 80 points, the comparison consistency was poor. The difference between the results of different detection systems was tested by paired sample T test or Wilcoxon paired sign rank sum test; The best cut-off point of diabetes was analyzed by receiver operating characteristic curve (ROC). Results: The correlation coefficient R2 of results between Lanyi AH600 and the reference instrument in 16 hospitals is≥0.99; The Bland Altman consistency analysis showed that the difference of 95% LoA in Nanjing Maternity and Child Health Care Hospital in Jiangsu Province (reference instrument: Arkray HA8180) was -0.486%-0.325%, and the measurement score was 94.6 points (473/500); The difference of 95% LoA in the Tibetan Traditional Medical Hospital of TAR (reference instrument: Bio-Rad Variant II) was -0.727%-0.612%, and the measurement score was 89.8 points; The difference of 95% LoA in the People's Hospital of Chongqing Liang Jiang New Area (reference instrument: Huizhong MQ-2000PT) was -0.231%-0.461%, and the measurement score was 96.6 points; The difference of 95% LoA in the Taihe Hospital of traditional Chinese Medicine in Anhui Province (reference instrument: Huizhong MQ-2000PT) was -0.469%-0.479%, and the measurement score was 91.9 points. The other 14 hospitals, Lanyi AH600, were compared with 4 reference instrument brands, the difference of 95% LoA was less than 0.4% HbA1c, and the scores were all greater than 95 points. The results of paired sample T test or Wilcoxon paired sign rank sum test showed that there was no statistically significant difference between Lanyi AH600 and the reference instrument Arkray HA8180 (Z=1.665,P=0.096), with no statistical difference. The mean difference between the measured values of the two instruments was 0.004%. The comparison data of Lanyi AH600 and the reference instrument of all other institutions had significant differences (all P<0.001), however, it was necessary to consider whether it was within the clinical acceptable range in combination with the results of the Bland-Altman consistency analysis. The ROC curve of HbA1c detected by Lanyi AH600 in 985 patients with diabetes and 3 423 patients with non-diabetes was analyzed, the area under curve (AUC) was 0.877, the standard error was 0.007, and the 95% confidence interval 95%CI was (0.864, 0.891), which was statistically significant (P<0.001). The maximum value of Youden index was 0.634, and the corresponding HbA1c cut point was 6.235%. The sensitivity and specificity of diabetes diagnosis were 76.2% and 87.2%, respectively. Conclusion: Among the hospitals and instruments currently included in this study, among these four hospitals included Nanjing Maternity and Child Health Care Hospital in Jiangsu Province (reference instrument: Arkray HA8180), Tibetan Traditional Medical Hospital of TAR (reference instrument: Bio-Rad Variant Ⅱ), the People's Hospital of Chongqing Liang Jiang New Area (reference instrument: Huizhong MQ-2000PT), and the Taihe Hospital of traditional Chinese Medicine in Anhui Province (reference instrument: Huizhong MQ-2000PT), the comparison between Lanyi AH600 and the reference instruments showed relatively good consistency, while the other 14 hospitals involved four different brands of reference instruments: Arkray, Bio-Rad, DOSOH, and Huizhong, Lanyi AH600 had good consistency with its comparison. The best cut point of the domestic Lanyi AH600 for detecting HbA1c in the diagnosis of diabetes is 6.235%.

ABSTRACT

Objective: To observe the effects of different frequencies of pricking-bloodletting at auricular points plus auricular point sticking therapy on the levels of the serum immunoglobulin G (IgG), immunoglobulin M (IgM), testosterone (T), and insulin-like growth factor-1 (IGF-1) in patients with acne vulgaris (AV). Methods: Ninety patients with AV were randomly assigned to treatment group 1, treatment group 2, and treatment group 3 according to the random number remainder grouping method, with 30 cases in each group. All three groups received pricking-bloodletting at auricular points plus auricular point sticking therapy. Treatment group 1 was treated once a week, treatment group 2 was treated twice a week, and treatment group 3 was treated 3 times a week. Four-week treatment was taken as 1 treatment course, and 3 treatment courses were observed. On the day before the start of the study and on the day next to the end of each course, the global acne grading system (GAGS) score was recorded, and 3 mL of blood from the median cubital vein was collected to test the serum levels of IgG, IgM, T, and IGF-1. After 3 courses of treatment, the efficacy index was calculated according to the GAGS score, and the serum indicators in patients with effective treatment (efficacy index ≥20%) and complete sampling were analyzed. Results: A total of 60 patients were included in the final blood indicator analysis. After 3 courses of treatment, the intra-group comparisons showed that the serum IgG level increased significantly in patients in treatment group 1 (P<0.01); the serum T level decreased significantly in the female patients in treatment group 2 (P<0.05); the IGF-1 level significantly decreased in the patients in all three groups (P<0.05 or P<0.01). There were no significant differences in the serum levels of IgG, IgM, T, and IGF-1 among the three groups at each time point (P>0.05). Conclusion: Pricking-bloodletting at auricular points plus auricular point sticking therapy can affect the levels of serum IgG, T, and IGF-1 in AV patients. The level of the serum IGF-1 can be reduced by treatment once a week, twice a week, or 3 times a week. Treatment once a week can increase the patients' serum IgG level, and treatment twice a week can significantly decrease the serum T level in female patients. Reducing the serum IGF-1 level may be one of the action mechanisms of pricking-bloodletting at auricular points plus auricular point sticking therapy in treating AV.

ABSTRACT

Objective:To investigate the relationship between liver function and arterial stiffness in the physical examination population.Methods:A total of 9 111 people who received physical examination in the Health Management Center of Wuhan Tongji Hospital from January to December 2017 with an age of 18 and above and complete clinical data were included in this study. The subjects were divided into arterial stiffness group (3 252 cases) and the normal group (5 859 cases) according to the results of brachial-ankle artery pulse wave velocity (baPWV) examination. The liver function indicators were checked in all the subjects, including alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP) and glutamyl transpeptidase γ (GGT). According to interquartile range of the liver function indicators, the subjects were divided into 4 groups (group Q1- Q4). Multivariate logistic regression analysis and restricted cubic spline functions were used to explore the relationship between liver function and risk of arterial stiffness. Results:When the subjects were grouped by ALT, after adjusted for age and gender, the risk of arterial stiffness in the Q2 to Q4 groups was 1.260 (95% CI:1.093-1.452, P<0.05), 1.571 (95% CI:1.355-1.822, P<0.001) and 2.436 (95% CI:2.097-2.830, P<0.001) times of that in the Q1 group, respectively, P for trend<0.001. And after adjusted for age, gender, body mass index, low-density lipoprotein cholesterol (LDL-C), triglycerides, high-density lipoprotein cholesterol (HDL-C), the risk of arterial stiffness in the Q2 to Q4 groups was 1.158 (95% CI:1.003-1.338, P<0.05), 1.331 (95% CI:1.143-1.551, P<0.001) and 1.867 (95% CI:1.591-2.190, P<0.001) times of that in the Q1 group, respectively, P for trend <0.001. After adjusted for age, gender, body mass index, LDL-C, triglycerides, HDL-C, systolic blood pressure, diastolic blood pressure, heart rate, fasting blood glucose, blood uric acid, serum creatinine, with or without hypertension or diabetes, the risk of arterial stiffness in the Q2 to Q4 groups was 1.116 (95% CI:0.940-1.325, P=0.210), 1.241 (95% CI:1.036-1.488, P<0.05) and 1.598 (95% CI:1.322-1.932, P<0.001) times of that in the Q1 group, respectively, P for trend <0.001. Restricted cubic spline regression analysis showed a linear positive correlation between ALT and the risk of arterial stiffness. Similar results as ALT obtained with AST, ALP and GGT. Conclusions:The increase of liver function indicators is positively correlated with the risk of arterial stiffness.

ABSTRACT

Objective:To investigate the intra- and inter-observer agreements of different experiencers using the Ovaria-adnexal Reporting and Data System (O-RADS) in the evaluation of adnexal masses.Methods:Totally 48 patients with adnexal masses (48 masses, mean size 9.5±4.7 cm, range 2.3-18.6 cm) found by ultrasound examination in the Third Affiliated Hospital of Sun Yat-sen University, from May 2019 to March 2020 were retrospectively analyzed. All the masses were confirmed by pathology or surgery. Four observers were divided into 2 senior doctors (Doctor 1 and Doctor 2) and 2 junior doctors (Doctor 3 and Doctor 4). Each observer independently evaluated adnexal masses twice using ultrasound O-RADS before and after systematic training, with an interval of 60 days. The intra-observer and inter-observer agreements were analyzed before and after training.Results:The inter-observer agreement between senior doctors were both excellent before and after systematic training (weight Kappa: 0.833 vs 0.802, percentage of agreement: 83.3% vs 81.3%). Whereas there was difference in the inter-observer agreement between non-experienced observers before and after training (weight Kappa: 0.399 vs 0.824, percentage of agreement: 50.0% vs 77.1%). After training, inter-observer agreement between junior doctors was significantly improved and comparable to senior (weight Kappa: 0.824 vs 0.802, percentage of agreement: 77.1% vs 81.3%). Before and after systematic training, the intra-observer agreements of the same doctor, the senior physicians were better than the junior (weight Kappa: 0.882 and 0.843 vs 0.440 and 0.605; percentage of agreement: 87.5% and 83.3% vs 58.3% and 54.2%).Conclusions:O-RADS risk classification system is a highly reproducible method in the subjective assessment of an adnexal mass among observers with varying levels of expertise. However, systematic training before clinical application is necessary and effective for non-experienced observers.

ABSTRACT

In order to research the mechanism of guiding action of borneol in Suxiaojiuxin pills, the model of in vitro intestinal absorption, in vivo drug metabolism of mice and cell in vitro absorption model of Caco-2 were established firstly. All animal experiments were in accordance with the regulations of the Animal Ethics Committee of Nankai University. The results showed that the cumulative absorption quantity and absorption permeability of ferulic acid and ligustilide in the intestinal juice of Suxiaojiuxin pills group were significantly increased comparing with fake Suxiaojiuxin pills group, which don't contain borneol. By using borneol, the content of ferulic acid and ligustilide in the blood and tissues, such as heart, were added. The transepithelial resistance value and the content of horseradish peroxidase (HRP) in Caco-2 were rapidly decreased and increased, respectively. Due to further explore mechanism of promoting intestinal absorption of borneol for drugs, in this study, photosensitive probes of borneol were synthesized to capture its targets, and dual luciferase reporter system was used to evaluate its activity of calcium. It was found that it could make calcium overload by regulating transient receptor potential cation channel, subfamily M, member 8 (TrpM8). Then, the results of mass spectrometry imaging showed that the accumulation of ferulic acid in the heart was significantly increased by borneol, and the relaxation rate of rat thoracic aorta was enhanced obviously. In summary, the borneol in Suxiaojiuxin pills can expand cell space and increase intestinal permeability by acting on TrpM8, thus promoting the intestinal absorption, tissue distribution and target organ enrichment of drugs.

ABSTRACT

OBJECTIVE@#To assess the effectiveness of Jiuwei Zhuhuang Powder (JWZH), a Tibetan patent medicine in treating upper respiratory tract infection (URTI) associated cough in children.@*METHODS@#The study was a multicenter, randomized, open-label, controlled trial. A total of 142 children aged 2 to 14 years old, with URTI-associated cough within 48 h of onset, were randomly assigned to two groups at a 1:1 ratio by computer-generated randomization sequence. Children were treated with JWZH (1 to 1.5 g, twice to thrice daily) in the treatment group or conventional treatment (Pediatric Paracetamol, Artificial Cow-bezoar and Chlorphenamine Maleate Granules, 0.25 to 1 g, thrice daily) in the control group for 5 days. The primary endpoints were the time to cough resolution and 4-day cough resolution rate. The secondary endpoints were the daily improvement in symptom scores and cough resolution rate during the study period.@*RESULTS@#A total of 138 children were included in the intention-to-treat analysis, with 71 cases in the treatment group and 67 cases in the control group. Compared with the conventional treatment, the children receiving JWZH had a shorter time to cough resolution [hazard ratio, 2.10; 95% confidence interval (CI), 1.29-3.40; P=0.003]. The median time to cough resolution for children receiving JWZH was shorter than that of the conventional treatment (2 days vs. 3 days; P<0.001). The 4-day cough resolution rate in the JWZH group was higher than that of the control group (94.4% vs. 74.6%; risk difference: 19.8%, 95% CI: 8.1%-31.5%; relative risk: 1.265, 95% CI: 1.088-1.470; P=0.001). There were no statistically significant differences in the improvement of other symptoms caused by URTI (P>0.05). Adverse events was reported in 5.6% (4/71) and 4.5% (3/67) in participants of JWZH and PPACCM groups (P>0.05), respectively, which were all mild and resolved without treatment.@*CONCLUSION@#JWZH seemed to be a safe and effective therapy for URTI-associated cough in children.

ABSTRACT

Objective:To explore the clinical features, follow-up characteristics and prognosis of rheumatic disease complicated with pulmonary arterial hypertension (PAH) in children, and to provide support for its clinical diagnosis and treatment.Methods:A retrospective analysis was conducted on the data of rheumatic 24 patients complicated with PAH hospitalized in the Department of Rheumatology and Immunology, Children′s Hospital Affiliated to the Capital Institute of Pediatrics, Department of Rheumatology and Immunology, Jiangxi Children′s Hospital, Department of Pediatrics Ⅰ, the First Affiliated Hospital of Zhengzhou University and Department of Pediatrics, the Affiliated Hospital of Inner Mongolia Medical University from January 2013 to June 2022.The rheumatic patients complicated with PAH were followed up by telephone on June 30, 2022, and their clinical symptoms, treatment, follow-up, and prognosis data were collected.According to different treatment methods, the patients were divided into different clinical subgroups. The change of PAH was analyzed. The t-test was used for comparison between groups. P<0.05 was statistically significant. Results:A total of 24 cases were enrolled, with 7 males and 17 females.The average onset age of PAH was (10.97±3.79) years old.The median duration of PAH was 6.00 (32.20) months.The average pulmonary artery pressure was (51.71±17.66) mmHg(1 mmHg=0.133 kPa). There were 9 cases of systemic lupus erythematosus, 5 cases of Takayasu′s arteritis, 3 cases of juvenile dermatomyositis, 3 cases of undifferentiated connective tissue disease, 2 cases of systemic juvenile idiopathic arthritis, 1 case of Behcet′s disease, and 1 case of Kawasaki disease.Among 24 cases, the common symptoms were fever (14 cases), fatigue (10 cases) and dyspnea (7 cases). Of the 24 cases, 10 cases were complicated with hydropericardium, 9 cases with valve regurgitation, and 5 cases with decreased systolic and/or diastolic function.Lung changes were observed in 17 cases.Eleven cases were tested for B-type natriuretic peptide (BNP), and the BNP levels were all elevated in them (11 cases), with a median BNP of 3 073 (10 645) ng/L.After the first occurrence of PAH, 12 cases were treated with Methylprednisolone therapy, 10 cases received Cyclophosphamide therapy, and 2 cases who were both systemic lupus erythematosus, underwent blood purification.In the treatment of PAH, 11 cases were treated with pulmonary artery pressure reduction, and 7 of the 11 cases took PAH-targeted drugs.The mean decrease of the average pulmonary artery pressure in children receiving the targeted therapy[(44.80±24.08) mmHg] was significant higher than that in children not receiving the targeted therapy [(16.15±17.25) mmHg] ( t=2.661, P=0.016). Twenty children were reexamined and/or followed up, and the average course of PAH at the telephone follow-up was (36.29±26.67) months.The pulmonary arterial hypertension in 6 cases completely recovered, with median recovery time of 8.00 (13.47) months, but 2 of them died after the complete recovery.The pulmonary arterial hypertension improved in 11 children, 1 of whom died and the remaining children were in stable condition.The pulmonary arterial hypertension worsened in 2 children, 1 of them improved previously but aggravated recently, and the other child did not monitor pulmonary artery pressure and died during telephone follow-up. Conclusions:Rheumatic diseases complicated with PAH are rare and most often diagnosed in severe rheumatic children.It can lead to death, and is commonly accompanied by notably elevated BNP levels.The patients who have early PAH detection, intensive treatment of the primary disease, symptomatic and targeted pulmonary artery pressure reduction show a better prognosis.

ABSTRACT

Antibody-mediated rejection (AMR) is one of the major causes of graft loss after transplantation. Recently, the regulation of B cell differentiation and the prevention of donor-specific antibody (DSA) production have gained increased attention in transplant research. Herein, we established a secondary allogeneic in vivo skin transplant model to study the effects of romidepsin (FK228) on DSA. The survival of grafted skins was monitored daily. The serum levels of DSA and the number of relevant immunocytes in the recipient spleens were evaluated by flow cytometry. Then, we isolated and purified B cells from B6 mouse spleens in vitro by magnetic bead sorting. The B cells were cultured with interleukin-4 (IL-4) and anti-clusters of differentiation 40 (CD40) antibody with or without FK228 treatment. The immunoglobulin G1 (IgG1) and IgM levels in the supernatant were evaluated by enzyme-linked immunosorbent assay (ELISA). Quantitative reverse transcription-polymerase chain reaction (RT-qPCR) and western blotting were conducted to determine the corresponding levels of messenger RNA (mRNA) and protein expression in cultured cells and the recipient spleens. The results showed that FK228 significantly improved the survival of allogeneic skin grafts. Moreover, FK228 inhibited DSA production in the serum along with the suppression of histone deacetylase 1 (HADC1) and HDAC2 and the upregulation of the acetylation of histones H2A and H3. It also inhibited the differentiation of B cells to plasma cells, decreased the transcription of positive regulatory domain-containing 1 (Prdm1) and X-box-binding protein 1 (Xbp1), and decreased the expression of phosphorylated inositol-requiring enzyme 1 α (p-IRE1α), XBP1, and B lymphocyte-induced maturation protein-1 (Blimp-1). In conclusion, FK228 could decrease the production of antibodies by B cells via inhibition of the IRE1α-XBP1 signaling pathway. Thus, FK228 is considered as a promising therapeutic agent for the clinical treatment of AMR.

ABSTRACT

Objective To explored the correlation between levels of serum calcium, phosphorus PTH and 99Tcm -MIBI in patients with hyperparathyropathy as well as to find cut off valve of serum calcium, phosphorus and PTH. Methods A total of 234 patients with hyperparathyroidism that confirmed by operation and pathology were collected from September 2017 to September 2019. Results The median PTH levels in PHPT group and SHPT group were 210.93 (122.60~529.20) pg/ml and 1842.50 (1342.50~2345.00) pg/ml, respectively. There was significant difference between the two groups (Z = − 10.83, P = 0.000). SHPT group was significantly higher than that in PHPT group. The median of Ca level of PHPT group and SHPT group was 2.86 (2.65~3.15) mmol/L and 2.43 (2.32~2.58) mmol/L, respectively. There was significant difference between the two groups (Z = −7.52, P = 0.000). The level of Ca in PHPT group was significantly higher than that in SHPT group. The median of P level in PHPT group and SHPT group was 0.80 (0.64~1.03) mmol/L and 2.26 (1.97~2.63) mmol/L respectively. There was significant difference between the two groups (Z = − 10.15, P = 0.000), and the PHPT group was significantly lower than the SHPT group. The age, gender, PTH and Ca and P value were taken as independent variables, and the results of MIBI imaging were used as dependent for logistic regression analysis. After screening, the influencing factor of PHPT group was PTH value (OR: 1.012, 95% CI: 1.002~1.023), and correlation analysis showed that r = 0.60 (P = 0.000). No related factors were found in SHPT group. ROC curves of 99Tcm-MIBI imaging results in PHPT group were drawn, corresponding to the areas under the maximum curve of 0.91, and the calculated cutoff value was 113.1 pg/mL. simple scatter plot of Ca value, P value and PTH value was drawn in PHPT group and SHPT group, and correlation analysis was performed. In PHPT group, Ca value and PTH value had moderate correlation (r = 0.64, P = 0.000), P value and PTH value had low correlation (r = − 0.28, P = 0.032); in SHPT group: Ca value and PTH value had low correlation (r = 0.17, P = 0.03), P value and PTH value had no correlation (P = 0.15). Conclusion The serum PTH level of PHPT was moderately correlated with MIBI imaging results. The higher the serum PTH level, the higher the positive rate of MIBI imaging, and the corresponding cutoff value of MIBI imaging was 113.1 pg/mL. There was a moderate correlation between serum Ca level and serum PTH level in PHPT, while in SHPT group low correlation between serum Ca level and serum PTH level.

ABSTRACT

OBJECTIVE@#To investigate the effect of tumor necrosis factor death receptor (DR) 4 demethylation to the proliferation and apoptosis of myeloid leukemia K562 cells.@*METHODS@#The logarithmic phase of K562 cells were treated by desitabine (DCA) at 0, 0.8, 1.6 and 3.2 μmol/L, and the cells were divided into control group, DCA low dose group, DCA medium dose group and DCA high dose group respectively. The cells in control group were treated by tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) 0.5 μg/ml for 24 h, and the cells were divided into TRAIL group. The cells in DCA high dose group were treated by TRAIL 0.5 μg/ml for 24 h, and were divided into DCA high dose + TRAIL group. Methylation-specific polymerase chain reaction (MS-PCR) was used to measure the methylation status of the DR4 gene promoter in the control group and DCA low, medium and high dose groups. Real-time fluorescent quantitative polymerase chain reaction (qRT-PCR) and Western blot were used to determine the relative expression of DR4 mRNA and protein in the control group and DCA low, medium and high dose groups. Dime- thylthiazole (MTT) method was used to determine the inhibition rate of cell proliferation of the cells in control group, DCA high dose group, TRAIL group, DCA high dose + TRAIL group. Flow cytometry was used to determine the apoptotic rate of the cells in control group, DCA high dose group, TRAIL group, DCA high dose + TRAIL group.@*RESULTS@#The cells in the control group were methylation-positive, the brightness of the methylation bands of the cells in the DCA low, medium, and high dose groups was gradually decreased to disappear, and the DCA high dose group showed negative for methylation. The relative expression of DR4 mRNA and protein in the control group, DCA low, medium and high dose groups was increased sequentially (r=0.624, 0.704). The inhibition rate of cell proliferation of the cells in the control group, DCA high dose group, TRAIL group, DCA high dose + TRAIL group was increased sequentially (r=0.653, 0.754, 0.709, 0.725) at 24, 48 and 72 h.@*CONCLUSION@#DCA can reverse the methylation level of DR4 gene promoter in ML K562 cells and up-regulate the expression of DR4, which may enhance the proliferation inhibition and apoptosis promotion effects of TRAIL on K562 cells.

ABSTRACT

Full application of marginal donor organs is a critical method to expand donor pool and alleviate organ shortage. After accurate donor evaluation, allocation and recipient selection, adult donor dual kidney transplantation (DKT) can not only achieve equivalent clinical efficacy to single kidney transplantation (SKT), but also effectively reduce the discard rate of marginal donor kidney. In this article, the clinical application and progress on adult donor DKT were reviewed from the perspectives of the development situation, allocation standard, recipient selection, surgical methods and complications as well as clinical efficacy of DKT, aiming to provide reference and guidance for subsequent development of marginal donor DKT.

ABSTRACT

Objective:To explore the outcome of kidney transplantation from donation after cadaveric death(DCD)with high pathological Remuzzi score.Methods:From January, 2019 to December, 2019, 31 recipients of kidney allograft transplantation from marginal donors with Remuzzi score≥4 in preimplantation biopsy were retrospectively enrolled. They were divided into two groups of dual kidney transplantation(DKT, 14 cases)and single kidney transplantation(SKT, 17 cases). Median Remuzzi score of left kidney(5.05 in DKT group vs 4.92 in SKT group)or right kidney(5.26 vs. 4.58)was comparable. Dual donor kidneys were implanted into ipsilateral iliac fossa. Survival outcomes, kidney function, acute rejection episodes, incidence of delayed graft function(DGF)and proteinuria were recorded within Year 1 post-operation.Results:Proportion of male(92.9% vs. 52.9%, P<0.05)and recipient's body mass index(BMI, 23.93 vs. 21.09)were significant higher in DKT group than those in SKT group. One graft failure occurred in DKT group at Month 11 post-operation. The 1-year graft survival rate was 92.9% in DKT group and 1-year recipient survival rate both 100% in two groups. Mean 12-month serum creatinine[SCr, (164±37.7)μmol/L vs. (154.92±96.2)μmol/L]and estimated glomerular filtration rate[eGFR, (41.84±9.01) vs. (44.8±18.16)ml/(min·1.73m 2)]were comparable between two groups(both P>0.05). There was no occurrence of thrombosis resulting in graft loss. One-year incidence of acute rejection, rate of DGF(42.9% vs 41.2%)and proteinuria(57.1% vs. 41.2%)were comparable between two groups(both P>0.05). Conclusions:Through donor-recipient matching and dual kidney transplant allocation, short-term survival outcome of kidney allograft from marginal donors with high Remuzzi score≥4 is encouraging. However, long-term outcomes should be further examined.

ABSTRACT

Objective:To investigate the value of translabial ultrasound (TLUS) in female periurethral benign solid lesions (PBSL).Methods:Twenty-one female patients (21 lesions) with PBSL identified pathologically within the process of cystoscope or surgery from June 2017 to December 2020 were enrolled. All of them underwent urethral examination (UE) and TLUS. The detection rates of the lesions of UE and TLUS were compared, and the ultrasonic diagnostic accuracy and ultrasonic manifestations were analyzed.Results:Sixteen of the 21 patients showed lower urinary tract symptoms (76.19%). Among the 21 lesions, the detection rates of UE and TLUS were 52.38% (11/21) and 85.71% (18/21), respectively, the difference was statistically significant ( P=0.019). The length of 18 lesions detected by TLUS was (1.79±1.04)cm, and 13 lesions (72.22%) were shorter than 3 cm. Among 18 cases, urethral caruncle (13 cases) was the most common benign periurethral mass, the main ultrasonic manifestations of urethral caruncle showed hyperecho lesions in the middle and distal urethra, and the blood flow was mostly in a branch-like distribution. At the same time, there were 5 cases of urethral myoma and other solid lesions, the main ultrasonic manifestations of urethral myoma showed clear boundary, low echo and peripheral short strip blood flow. Using pathological results as the gold standard, the accuracy of ultrasonic diagnosis was 88.89% (16/18). Conclusions:TLUS is able to improve the detection rate of periurethral benign solid lesions, and the diagnostic concordant rate is acceptable.TLUS can provide more diagnostic and therapeutic information.

ABSTRACT

Objective:To discuss the risk factors, treatment process and prevention strategy of the cases of acute pulmonary embolism after cerebral hemorrhage, so as to improve the attention and level of the disease.Methods:The data of a patient with cerebral hemorrhage and acute pulmonary embolism treated in Lianyungang First People's Hospital were analyzed retrospectively, and the literature related to intracerebral hemorrhage complicated with acute pulmonary embolism was reviewed.Results:One week after intracerebral hemorrhage, the patient was diagnosed with acute pulmonary embolism and given anticoagulant treatment with low molecular weight heparin. The condition was alleviated without aggravating intracerebral hemorrhage. Lying in bed after intracerebral hemorrhage, limb braking, use of dehydration, diuresis, hemostasis and other drugs were the high-risk factors of pulmonary embolism.Venous thromboembolism can be prevented clinically by physical methods and drugs.Conclusions:Venous thromboembolism is easy to occur after intracerebral hemorrhage. Clinically, the incidence can be reduced by pneumatic therapy or anticoagulant drugs. In treatment, it is necessary to weigh the risk of death of pulmonary embolism and rebleeding. After comprehensive evaluation, we can formulate an individualized treatment plan. It may be safe and effective to use low molecular weight heparin to treat pulmonary embolism after the intracerebral hemorrhage hematoma is stable.

ABSTRACT

Symptomatology and medical history taking are the focuses of diagnostics study. With the improvement of teaching and learning, students can basically master the standard process of clinical inquiry of chief complaints to family history efficiently. However, due to the lack of systematic learning of clinical diseases, it's difficult for most students to form a targeted, logical and speculative inquiry thinking pattern, so they are unlikely to write a medical history of present illness that reflects their thinking on disease inclusion and exclusion. In this study, we come up with the characteristics and defects of symptomatology teaching at present, and put forward a new idea of symptomatology teaching by introducing clinical manifestations of diseases and examples of inquiry.

ABSTRACT

Objective:To evaluate the enrollment rate, mutation rate and causes of variability the clinical pathway of bronchopneumonia.Methods:The enrollment rate, completion rate, variation and reasons of the clinical pathway in Beijing Children′s Hospital, Capital Medical University from January 2012 to December 2016 were retrospectively collected.Data of patients after the clinical pathway of bronchopneumonia in other tertiary class A hospitals were gathered by questionnaires, and the enrollment rate, completion rate, variation rate and reasons were analyzed.Results:(1)At the end of 2016, 11 of the 13 hospitals included in this study had implemented the clinical pathway for 5 years, 1 hospital for 3 years, and 1 hospital for 2 years.(2) Eleven hospitals provided their enrollment rates.The enrollement rate of 2 hospitals was<50%, and that of 9 hospitals was>80%.The annual completion rate of Beijing Children′s Hospital was ≥75%, and the completion rates offered by 8 hospitals were basically >70%.(3) Since the implementation of the clinical pathway for 5 years in Beijing Children′s Hospital, a total of 427 cases were enrolled of which 93 cases were mutated (variability 21.78%). The variability of 5 hospitals was maintained at <15%.The variability of 3 hospitals decreased with the implementation years, and became qualified.The variability of 1 hospital first rebounded and then controlled; 1 hospital increased by 27.65%; 1 hospital was first controlled and rebounded; 1 hospital was always >15%.The main cause of the mutation was coexisting diseases, complications, progression of the disease, or correction of the first diagnosis, etc.Conclusions:The completion rate of tertiary class A hospitals meets the requirements of national policy.However, the enrollment rate needs to be improved, and the variation rate among different hospitals differs a lot.Further implementation of the clinical pathway should be strengthened and monitored.

ABSTRACT

Objective::To study the effect of evodia on lipid metabolism and low-density lipoprotein-receptor(LDL-R) mRNA expression in hyperlipidemia mice. Method::Kunming mice (n=80) were randomly divided into normal control group (n=20) and model group (n=60). Serum lipids of the model group were measured after 3 weeks.After successful modeling, the mice can be randomly divided into 5 groups (with 10 in each group): model group (equivalent normal saline), positive control group (simvastatin, 5 mg·kg-1·d-1), drug group (evodia of 5.25, 10.5, 21 mg·kg- 1·d- 1). The mice were given drugs for 3 weeks.Htoxylin-eosin(HE) staining was used to observe the liver cell structure and the change of aortic arch atherosclerosis in the mice.The enzyme linked immunosorbent assay kit was used to test the contents of total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C) and total serum adiponectin (ADPN) in serum of the mice.The expression of LDL-R mRNA in liver of each group was detected by reverse transcription-polymerase chain reaction (RT-PCR). Result::Liver HE staining showed hepatocyte swelling with steatosis in the model group, and alleviated liver steatosis in high-dose, medium-dose evodia and simvastatin groups.HE staining showed damages on the aortict arch wall in the model group, with obvious intima thickening and inflammatory cell infiltration.The intima was thickened obviously in the low-dose group, and the structure of aortic vessel wall was clear in the high-dose group.Compared with the normal group, TC, TG and HDL-C levels in serum of the model group were increased, while HDL-C level was decreased (P<0.01). Serum TC and TG levels of mice in the medium and high-dose groups decreased, whereas LDL-C and HDLl-C levels increased in low, medium and high-dose groups (P<0.05, P<0.01). Compared with the normal group, the adiponectin level in the model group was decreased, while the serum adiponectin levels in medium and high-dose groups were significantly increased (P<0.01). The LDL-R mRNA expression in the liver of mice in the model group was significantly reduced compared with the normal group (P<0.01). The LDL-R mRNA expression in medium and high-dose evodia groups was significantly increased compared with the model group (P<0.01). Conclusion::Evodia can improve the tendency of hepatic lesions and aortic atherosclerosis in hyperlipidemia mice, which may be related to the regulation of adiponectin level, the reduction of lipid content in mice and the up-regulation of LDL-R mRNA expression in mice liver.

ABSTRACT

Objective: To observe the blood perfusion volume variation pattern in the body surface microcirculation at the Yuan-Primary and the Xi-Cleft points during the menstrual cycle in female college students with moderate constitution under normal physiological state of the uterus; to explore the specific laws of the body surface microcirculation at the Yuan-Primary and Xi-Cleft points in response to the uterine qi and blood changes under normal physiological conditions, and to provide the experimental basis for the specificity of acupoints reflecting the uterine function. Methods: Forty-three healthy and moderate constitution female college students with regular menstrual cycles, without dysmenorrhea and not yet giving birth were recruited. Bilateral Yuan-Primary points [Taichong (LR 3), Taibai (SP 3) and Taixi (KI 3)] and Xi-Cleft points [Zhongdu (LR 6), Diji (SP 8) and Shuiquan (KI 5)], belonging to the three yin meridians of foot and adjacent to the spinal cord segment of the uterus, were selected as the detection acupoints; the crossing point of the three yin meridians of foot [Sanyinjiao (SP 6)], the uterus-related meridian acupoint [Xuehai (SP 10)], the uterus-non-related meridian acupoint [Xuanzhong (GB 39)], and the non-meridian non-acupoint point were selected as the control points. The laser speckle blood flow imaging technique was used to monitor the blood perfusion volume in skin microcirculation at the above points at the menstrual, follicular, ovulatory, and luteal phases of the subjects. Results: The blood perfusion volume in the body surface microcirculation at the right Zhongdu (LR 6) at the ovulatory phase was higher than that at the menstrual, follicular and luteal phases (all P<0.05); there was no significant difference in the microcirculation blood perfusion volume at the other points among different phases (all P>0.05). Conclusion: The blood perfusion volume in the body surface microcirculation at Zhongdu (LR 6), the Xi-Cleft point of the Liver Meridian, shows a specific response to qi and blood changes in the uterus of women with moderate constitution.

ABSTRACT

Objective:To explore the value of 3D/4D translabial ultrasound in the diagnosis and differential diagnosis of female urethral diverticulum.Methods:The paired chi-square test was used to compare the diagnostic accuracy of 2D translabial ultrasound and 3D/4D translabial ultrasound in 21 suspected urethral diverticulum patients who visited the Third Affiliated Hospital of Sun Yat-Sen University from November 2013 to January 2020. And Kappa consistency test was used to evaluate the consistency between these two methods and the pathological results.Results:All 21 patients with suspected urethral diverticulum were diagnosed by postoperative pathology, of which 16 cases were urethral diverticula and 5 cases were paraurethral cysts. The typical appearance of urethral diverticulum on 3D/4D translabial ultrasound was a cystic structure traversing the urethral rhabdosphincter. Additionally, septa, calcification or solid neoplasm can also be seen in some cases. The sensitivity/specificity of 2D translabial ultrasound and 3D/4D translabial ultrasound were 75.00%/100% and 93.75%/100%, respectively, no statistical differences were found both in sensitivity and specificity between these two methods(all P>0.05). The Kappa consistency test showed that the consistency between 2D translabial ultrasound and pathological diagnosis was general (Kappa=0.588, P=0.003), while the consistency between 3D/4D translabial ultrasound and pathological diagnosis was good (Kappa=0.877, P<0.001). Conclusions:3D/4D translabial ultrasound has a high value in the diagnosis of female urethral diverticulum, and it is worthy of clinical application.
