Objective : To investigate the distribution of solute carrier organic anion transporter family member 1B1(SLCO1B1) and apolipoprotein E(ApoE) gene polymorphisms in the patients of Han ethnic group with cardiovascular and cerebrovascular diseases from Anhui Province, in order to provide the basis for the individualized therapy of statins in clinical practice. Methods: 924 Han patients with cardiovascular and cerebrovascular diseases were selected. The SLCO1B1 and ApoE genotypes of the patients were detected by polymerase chain reaction-fluorescent probe method, and their distribution was compared among different genders and other regions in China. Results: Seven SLCO1B1 gene subtypes were detected in 924 patients, including *1a/*1b(33.01%),*1b/*1b(41.45%), *1b/*15(12.34%), *1a/*1a(7.03%), *1a/*15(5.52%), *15/*15(0.54%) and *5/*5(0.11%), without detection of the two gene subtypes of *1a/*5 and *5/*15; the normal metabolic genotype I of SLCO1B1(*1a/*1a, *1a/*1b, *1b/*1b) accounted for the highest proportion in this population(81.49%), the intermediate metabolic genotype II and the weak metabolic genotype III of SLCO1B1 accounted for 17.86% and 0.65% respectively; six ApoE gene subtypes were detected, including E3/E3(66.78%), E3/E4(19.37%), E2/E3(9.63%), E4/E4(1.84%), E2/E4(1.73%) and E2/E2(0.65%); the E3 mass genotype(E2/E4, E3/E3) accounted for the highest proportion in this population(68.51%); there was no significant difference in the distribution of SLCO1B1 and ApoE genes between different genders; there was no significant difference in the distribution of SLCO1B1 between the Han population from Anhui and the South China and Central China, but a significant difference was found between the Anhui Han population and the Southwest China(P<0.05); the distribution of ApoE in the Anhui Han population demonstrated no statistically significant variation from those in South China and Southwest China, whereas significant differences were observed in comparison with Central China(P<0.05). Conclusion In the Han population with cardiovascular and cerebrovascular diseases in Anhui, the distributions of SLCO1B1 and ApoE gene polymorphisms show no significant gender differences but exhibit regional variations. These populations are predominantly characterized by class I normal metabolic genotype(SLCO1B1) and E3 mass genotypes(ApoE), indicating a higher tolerance to statin dosages and normal therapeutic efficacy in this cohort.

【Objective】 To study the relationship between ABO subtype, para-Bombay blood group and genotype, so as to explore the possible molecular mechanism of these two blood groups, and provide accurate genetic detection targets and theoretical basis for the accurate identification of ABO blood group. 【Methods】 First, the serology of 24 200 patients with blood type identification in the Ruijin Hospital from February to December in 2022 were analyzed, as well as 10 ambiguous ABO samples from other hospitals(3 were suspected ABO subtype and 7 were suspected para-Bombay blood group). Then ABO subtypes and para-Bombay blood groups were directly sequenced or post-clonal sequencing was performed to analyze ABO, FUT1 and FUT2 gene sequences. 【Results】 Among the 24 200 patients underwent blood type identification, 7 cases of ABO subtypes were detected. Among the 10 ambiguous samples sent by other hospitals, 2 of ABO subtypes, 1 of normal type A, and 7 of para-Bombay blood type were detected. In total, we identified blood types as follows: 1) 9 ABO subtypes: Ael(AEL.02/O.01.02), AelB(AEL.05/B.01), three of B3(2 of B3.03/O.01.01, 1 of B3.03/O.01.02), B(A)(BA.02/O.01.01), ABweak(A1.02/BW.07), Bweak(BW.31 /O.01.02), A2Bweak(A2.05 /BW.31); 2) 7 para-Bombay blood group: ABm^h (FUT1^*01N.13/FUT1^*01N.13), 4 of Am^h (3 of FUT1^*01N.06/FUT1^*01N.13, 1 of FUT1^*01N.13/FUT1^*01N.13); two of Bm^h (FUT1^*01N.06 /FUT1^*01N.06, FUT1^*01N.06/FUT1^*01N.13), all of FUT2 of the 7 cases were FUT2^*01/FUT2^*01. 【Conclusion】 Clinical ABO blood group variant samples need to be identified in combination with serological and molecular biology to improve the accuracy of identification, thus providing a reference for safe blood transfusion, organ transplantation, and the prediction and prevention of fetal-maternal immune hemolytic disease.

OBJECTIVE To establish the HPLC fingerprint and content determination of five components in Ranunculus sceleratus L.. METHODS The separation was developed on an Agilent ZORBAX SB C18 chromatographic (4.6 mm×250 mm, 5 μm)column by gradient elution with methanol(A)-0.1 % phosphoric acid aqueous solution(B) as mobile phase to establish HPLC fingerprint of Ranunculus sceleratus L.. Combined with similarity evaluation, cluster analysis, principal component analysis, and orthogonal partial least squares-discriminant analysis, the quality of 13 batches of Ranunculus sceleratus L. was evaluated. RESULTS Thirteen batches of Ranunculus sceleratus L. samples were calibrated with 20 common peaks, of which 5 common peaks were identified, and the similarity ranged from 0.874 to 0.984. The results of cluster analysis and principal component analysis were basically the same, indicating that there might be differences in the content of chemical components of Ranunculus sceleratus L. in different regions. Protocatechuic aldehyde, caffeic acid, ferulic acid, hyperoside and isoquercitrin were determined in thirteen batches of Ranunculus sceleratus L., and their contents were 0.016−0.035, 0.010−0.070, 0.010−0.029, 0.016−0.051, 0.028−0.086 mg·g–1, respectively. CONCLUSION The established HPLC fingerprint and content determination method is simple, stable, and reliable, which can be used for qualitative analysis and provide reference to quality evaluation and resource utilization of Ranunculus sceleratus L..

Objective: To evaluate the effectiveness and safety of modified Xiaoyao powder for postpartum depression (PPD) by conducting a systematic review of randomized controlled trials (RCTs). Methods: The Chinese National Knowledge Infrastructure Databases (CNKI), the Chinese Scientific Journals Database (VIP), Wanfang, Google Scholar, the SinoMed, Embase, Cochrane Library, and PubMed databases were searched from their inception to April 25, 2023. The Cochrane Risk of Bias tool was used to assess the quality of the trials. We applied the risk ratio to present dichotomous data and the mean difference to present continuous data. Data with similar characteristics were pooled for meta-analysis and heterogeneity was assessed using I2. Results: This review included 35 trials involving 2848 participants. The quality of the included studies was low (unclear randomization processes and insufficient reporting of blinding). Participants treated with modified Xiaoyao powder plus Western medicine showed lower Hamilton Depression Scale (HAMD) depression score than those who used Western medicine alone (mean difference = −2.15; 95% confidence interval:−2.52 to 1.78; P < .00001), and higher effective rate (relative risk = 1.19; 95% confidence interval: 1.15 to 1.24; P < .00001), When comparing modified Xiaoyao alone with Western medicine, the HAMD depression score remained low, however, the efficacy rate was higher in the modified Xiaoyao group. Regarding adverse events, the modified Xiaoyao group reported weight gain, nausea, and diarrhea, but no severe adverse events were reported. Conclusion Modified Xiaoyao may help relieve depression in PPD when used alone or in combination with Western medicine, with minor side effects. Therefore, future high-quality, large-sample size RCTs are warranted.

Objective To compare the effectiveness of different β-blockers for preventing postoperative atrial fibrillation (POAF) after cardiac surgery. Methods Databases of PubMed, Science Direct, Web of Science, The Cochrane Library, SinoMed, CKNI, VIP, WanFang were searched by the computer from inception to April 31, 2022 to collect randomized controlled studies on the comparison of the effectiveness of different β-blockers for preventing POAF. Two investigators independently screened the literature and extracted information. The quality of the literature was evaluated using Cochrane bias risk tool, and RevMan 5.3 and STATA 17.0 were used for meta-analysis. Results A total of 17 randomized controlled studies with 3 290 patients were included. Direct meta-analysis showed that landiolol and metoprolol were more effective than placebo (P≤0.001), and carvedilol was more effective than metoprolol in preventing the development of POAF (P<0.001). Network meta-analysis showed that landiolol, carvedilol and metoprolol were more effective than placebo in preventing the incidence of POAF (P<0.05). Landiolol and carvedilol were more effective than metoprolol, and carvedilol were more effective than nebivolol (P<0.05). The surface under the cumulative ranking curve from high to low were carvedilol, landilol, propranolol, atenolol, metoprolol, and nebivolol. Conclusion Carvedilol and landilol have different degrees of improvement in the occurrence of POAF, and carvedilol has the best preventive effect. More studies are required to verify the strength of evidence due to the limited sample size.

Objective:To retrospectively analyze the clinical characteristics and renal involvement in children with neurofibromatosis type 1 (NF1), in order to provide reference for the clinical assessment and management of these patients.Methods:A case series report.Basic information, admission conditions, clinical manifestations, laboratory and renal imaging findings, as well as follow-up data of children diagnosed with NF1 at Wuhan Children′s Hospital of Tongji Medical College, Huazhong University of Science and Technology from January 2019 to December 2023 were retrospectively collected and analyzed.Descriptive statistics were used to summarize the clinical features of renal phenotypes associated with NF1 in this cohort.Results:A total of 102 children with NF1 were included in the study, including 64 males and 38 females, with a male-to-female ratio of approximately 1.7∶1.0, and the median age was 5.6 years.The majority of initial consultations were in the departments of neurology, orthopedics, and general surgery, with 3 cases in the nephrology department.Renal involvement was observed in 8 children (7.8%), including 4 cases with abnormal urine tests (2 cases of proteinuria and 2 cases of microscopic hematuria) and 4 cases with hydronephrosis.All children had normal serum creatinine levels.Blood pressure monitoring was performed in 51 children, including 5 cases(9.8%) with prehypertension and 13 cases(25.5%) with hypertension.Conclusions:NF1 is a multisystem disorder, and children with NF1 are prone to develop glomerular diseases, urinary tract abnormalities and renal vascular lesions.Urological manifestations are often subtle, making them easily overlooked in clinical practice.Therefore, it is recommended to regularly conduct blood pressure, renal function, urine routine, and urinary imaging examinations for NF1 children in order to detect and manage them early and improve their long-term prognosis.

Antenatal hydronephrosis（AHN）is the most common congenital anomalies of kidney and urinary tract（CAKUT）detected through prenatal ultrasound screening.Approximately two-thirds of AHN are physiological and can be relieved spontaneously after birth，while AHN may be aggravated in some cases，resulting in deterioration of kidney function or severe complications and requiring surgical intervention.Currently，there is a lack of consensus on the prenatal and postnatal management of AHN，making it crucial to stratify the risk for affected children and establish appropriate follow-up plans.This article reviews the clinical assessment and management of AHN in prenatal and postnatal settings based on domestic and international literature，with the goal of raising AHN awareness among families of high-risk children and alleviating anxiety and excessive intervention for families of low-risk children，ultimately promoting individualized diagnosis and treatment.

Objective To investigate the effect of cysteine-rich acidic secretory protein-like protein 1(SPARCL1)on atherosclerosis(AS)plaque formation.Methods A case-control study design was used,394 patients with con-firmed AS were selected as the case group,and 394 healthy medical examiners matched for age and gender were se-lected as the control group.The expression level of serum SPARCL1 was determined by enzyme-linked immunosor-bent assay;immunohistochemistry was used to assess the expression level and localization of SPARCL1 protein in the AS plaque region,and the expression of SPARCL1 protein was also detected in the neutrophils and monocytes of peripheral blood of AS patients and normal controls;SPARCL1 overexpressing and the recombinant adenoviral vec-tors were constructed to inhibit SPARCL1 overexpression and expression,and the effects of SPARCL1 on cell mi-gration were observed in the cell scratch assay using mouse macrophage cells(J774A.1)as target cells.Results Serum SPARCL1 levels in the AS patient group were lower than those in the healthy group(P<0.05);high SPARCL1 expression was detected in AS plaques and was mainly expressed in the cytoplasm of foamy cells;SPARCL1 expression levels in peripheral blood neutrophils and monocytes were lower than those in normal controls in AS patients(P<0.05);recombinant SPARCL1 overexpression and inhibition of expression of adenovirus was successfully constructed;the cell migration rate was decreased in J774A.1 cells that inhibited SPARCL1 expression and increased in J774A.1 cells that overexpressed SPARCL1(P<0.05).Conclusion SPARCL1 is highly ex-pressed in foam cells at the site of AS lesions,which may result from compensatory recruitment of peripheral blood monocytes and neutrophils,and SPARCL1 may be involved as a protective factors for blood vessels in inhibiting the development of AS plaques.

Objective: To investigate the expression of secreted protein acidic and rich in cysteine⁃like 1 (SPARCL1) in atherosclerosis (AS) and the association between SPARCL1 gene rs7695558 and rs1049539 polymorphism with the susceptibility to AS. Methods : In this case⁃control study ,209 AS patients were selected as the case group , and 208 healthy matched in age and sex were selected as the control group. The expression level of serum SPARCL1 was measured by enzyme⁃linked immunosorbent assay (ELISA) . Linear and Logistic regression analysis were used to evaluate the correlation between SPARCL1 level and vascular risk factors , lifestyle and demographic variables. Expression of SPARCL1 in tissue specimens was assessed by immunohistochemistry. Single nucleotide polymorphisms (SNPs) were genotyped by high resolution melting method. Chi⁃square test was used to analyze the relationship between rs7695558 and rs1049539 polymorphism and susceptibility to AS. Results: The serum expression level of SPARCL1 in AS patients was lower than that in healthy controls (Z = - 2. 916 ,P = 0. 004) . The level of SPARCL1 was related to age (P = 0. 027) and diastolic blood pressure ( P = 0. 008) , but not to sex and other cardiovascular risk factors (P > 0. 05) . The expression level of SPARCL1 in atherosclerotic lesions of coronary artery tissue increased. There was no significant difference in gene distribution of rs7695558 and rs1049539 between the case group and the control group by chi⁃square test (P > 0. 05) . In the recessive genetic model of rs7695558 , there was a difference in the distribution of genes with and without A. Patients without A allele (GG) had a lower risk of AS than patients with A allele (AA + AG) . The OR value was 0. 417 ,95% CI :0. 184 ~ 0. 945 , which was significant at 10% confidence level ( P = 0. 034) . Conclusion Rs7695558 , a new susceptible site related to AS risk , located in the intron of human SPARCL1 gene is identified for the first time in Anhui population of China , suggesting that SPARCL1 may play an anti⁃AS role as a vascular protective factor.

Objective    To analyze the perioperative safety and the short-term prognosis of non-small cell lung cancer (NSCLC) patients with preoperative arrhythmia. Methods    The clinical data of NSCLC patients treated in the Department of Cardiothoracic Surgery, the First Affiliated Hospital of Chongqing Medical University from August 2020 to March 2021 were collected and observed. The patients were divided into an arrhythmia group and a control group according to whether there was arrhythmia in the 24 h ambulatory electrocardiogram examination report before operation. The incidence of intraoperative and postoperative cardiovascular events and short-term prognosis were compared between the two groups. Results     A total of 466 patients were included in this study, including 338 patients in the arrhythmia group, 176 males and 162 females, with a median age of 68.0 (63.0, 72.0) years, and 128 patients in the control group, 59 males and 69 females, with a median age of 66.5 (60.0, 72.0) years. A total of 26 patients (7.7%) in the arrhythmia group were placed with temporary pacemakers before operation. There was no significant difference in the incidence of cardiovascular related events between the two groups [100 (29.6%) vs. 28 (21.9%), P=0.096]. The incidence of postoperative arrhythmia events in the arrhythmia group was higher than that in the control group [112 (33.1%) vs. 11 (8.6%), P<0.001]. The average postoperative ICU stay in the arrhythmia group was longer than that in the control group (1.1±0.7 d vs. 1.0±0.6 d, P=0.039). Conclusion    Preoperative arrhythmia does not increase the risk of intraoperative cardiovascular events in NSCLC patients, but increases the incidence of postoperative arrhythmia events and prolongs ICU stay.
