Postpartum lumbopelvic pain(PLPP)occurs in women during the period from pregnancy to the puerperium.Its root cause lies in the deficiency of qi and blood,and the key pathogenesis is the imbalance of qi and blood,leading to meridian blockage.When treating PLPP clinically,it is essential to focus on its pathogenesis and address both the root and the symptoms.Acupuncture points from the spleen meridian,stomach meridian,kidney meridian,conception vessel,and governor vessel are selected to tonify qi,nourish blood,replenish the kidneys,and fill essence to treat the root.Acupuncture points from the liver meridian,heart meridian,and bladder meridian are chosen to regulate qi,activate blood,calm the mind,and dispel cold and dampness to alleviate the symptoms.Ultimately,this approach aims to achieve a state of harmonious qi and blood and smooth meridians,providing a clinical acupuncture strategy for the treatment of PLPP.

Diabetic retinopathy(DR)is a common complication of diabetes.Sodium-glucose cotransporter 2(SGLT-2)inhibitors are widely used in diabetic patients as hypoglycemic drugs and also play a role in the prevention and treatment of DR.At present,there has been no systematic study on the clinical treatment of DR by SGLT-2 inhibitors.This paper re-views the research progress of SGLT-2 inhibitors in the treatment of DR,in order to provide more ideas for the clinical treatment of DR.

Objective We aimed to investigate the relationship between microscopic pattern of blood stasis and renal pathological grade and related physical and chemical indexes in children with Henoch-Sch?nlein purpura nephritis(HSPN).Methods We conducted a retrospective analysis of 800 HSPN children from the medical records of the First Affiliated Hospital of Henan University of Chinese Medicine.Laboratory indicators(blood routine test,urine routine test,coagulation test,liver function)and renal pathological indicators of them were collected.According to the severity of renal pathological microscopic lesions,the microscopic pattern of blood stasis was divided into three types,including choroidal discord,dead blood coagulation and intracarenal disease accumulation.The classification of renal microscopic pattern of blood stasis and the correlation between laboratory indexes and renal pathological index were analyzed by Spearman grade correlation and binary Logistic regression analysis.Results(ⅰ)There was no statistical difference of the distribution of the renal microscopic pattern of blood stasis in the different traditional Chinese medicine patterns.(ⅱ)There were significant differences in the contents or the grade of albumin and fibrinogen in the HSPN children with different microscopic pattern of blood stasis(all P＜0.05).(ⅲ)The maximum area under the receiver operating characteristic(ROC)curve between fibrinogen and intracarenal disease accumulation was 0.594(95％CI from 0.540 to 0.633,P＜0.001);sensitivity was 0.447,specificity was 0.725;the best threshold on the ROC curve of 0.172 was 3.755 g/L.(ⅳ)There were positive correlations between the content of fibrinogen,ISKDC grade and Bohle A grade respectively with the scores of intracarenal disease accumulation type(r=0.176,r=0.315,r=0.656;all P＜0.001).(ⅴ)There were positive correlations between the content of fibrinogen,ISKDC grade and Bohle A grade respectively with the renal microscopic pattern of blood stasis(r=0.157,r=0.377,r=0.429;all P＜0.001).Conclusion The microscopic renal pattern of blood stasis can not only reflect the severity of renal blood stasis,but also reflect the severity and long-term prognosis of renal diseases.Albumin and urinary protein grade can reflect the early stage of the microscopic renal pattern of the blood stasis(choroidal discord).The content of fibrinogen increases with the aggravation of renal microscopic pattern of blood stasis,reflecting the end-stage of HSPN,which has the correlation with the formation and severity of related indexes.Fibrinogen can be used as a laboratory indicator to assist in the diagnosis of irreversible lesionsin the renal pathology of HSPN children.

Here, we report a previously unrecognized syndromic neurodevelopmental disorder associated with biallelic loss-of-function variants in the RBM42 gene. The patient is a 2-year-old female with severe central nervous system (CNS) abnormalities, hypotonia, hearing loss, congenital heart defects, and dysmorphic facial features. Familial whole-exome sequencing (WES) reveals that the patient has two compound heterozygous variants, c.304C>T (p.R102*) and c.1312G>A (p.A438T), in the RBM42 gene which encodes an integral component of splicing complex in the RNA-binding motif protein family. The p.A438T variant is in the RRM domain which impairs RBM42 protein stability in vivo. Additionally, p.A438T disrupts the interaction of RBM42 with hnRNP K, which is the causative gene for Au-Kline syndrome with overlapping disease characteristics seen in the index patient. The human R102* or A438T mutant protein failed to fully rescue the growth defects of RBM42 ortholog knockout ΔFgRbp1 in Fusarium while it was rescued by the wild-type (WT) human RBM42. A mouse model carrying Rbm42 compound heterozygous variants, c.280C>T (p.Q94*) and c.1306_1308delinsACA (p.A436T), demonstrated gross fetal developmental defects and most of the double mutant animals died by E13.5. RNA-seq data confirmed that Rbm42 was involved in neurological and myocardial functions with an essential role in alternative splicing (AS). Overall, we present clinical, genetic, and functional data to demonstrate that defects in RBM42 constitute the underlying etiology of a new neurodevelopmental disease which links the dysregulation of global AS to abnormal embryonic development.

Purpose To evaluate the added value of time of flight(TOF)and point spread dispersion(PSF)reconstruction in mediastinal lymph node metastasis of lung cancer in 18F-FDG PET/CT imaging.Materials and Methods Sixty-eight lung cancer patients with mediastinal lymph node metastasis who underwent PET/CT examination in the First People's Hospital of Foshan from March 9,2020 to July 23,2021 were analyzed retrospectively.The different methods,including ordered subsets estimation maximization(OSEM),OSEM+TOF,OSEM+PSF,OSEM+TOF+PSF,were used to reconstruct the images.The resolution of different reconstruction algorithms for mediastinal lymph node metastasis of lung cancer,as well as the differences of signal-to-noise ratio(SNR)and standard uptake value(SUV)were compared,respectively.Results The highest values of SUVmean,SUVmax and SNR were obtained via OSEM+TOF+PSF method,which increased by 21.99%,22.86%and 60.14%,compared with conventional OSEM method(t=28.321,19.11,11.059,all P<0.01).The difference percentage in smaller lesions that diameter≤22 mm was significantly higher than that in larger lesions that diameter>22 mm(24.1%vs.21.1%,25.3%vs.19.3%,70.6%vs.63.3%;Z=-3.658,-4.313,-2.154,all P<0.05),and the difference percentage in low contrast lesions that SNR≤15.31 was significantly higher than that in high contrast lesions that SNR>15.31(23.6%vs.21.4%,25.3%vs.21.1%,85.7%vs.46.0%;Z=-3.519,-2.336,-5.106,all P<0.05).Among the evaluation results of lesion detectability of different reconstruction algorithms,OSEM+TOF+PSF image showed the mediastinal lymph node metastasis most clearly(87.4%of the lesions were clearly existing),which was significantly higher than that of OSEM image(73.1%of lesions were clearly existing)(χ2=11.704,P=0.001),however,the proportion of lesions clearly existing in OSEM+PSF image did not significantly increase compared with OSEM image(73.1%vs.75.8%;χ2=0.361,P=0.548).Conclusion The combination of TOF and PSF can significantly improve the detection ability,SNR and SUV of mediastinal lymph node metastasis of lung cancer,especially in small and low contrast lesions.

Objective To investigate the modeling of Henoch-Sch?nlein purpura nephritis based on data mining,and to provide a reference for the preparation of a standardized Henoch-Sch?nlein purpura nephritis animal model.Methods We searched the CNKI,Wanfang Data,VIP,China Biomedical Literature Database,and PubMed Chinese-English Database by computer to obtain studies of animal experiments relating to Henoch-Sch?nlein purpura nephritis in the past 20 years.The species,modeling method,dosage,dosing cycle,modeling standards,and detection indexes were screened manually,and a database was established by using Microsoft Excel 2021 software for statistical analysis.The association rules of high-frequency indicators were analyzed using SPSS Modeler 18.0,and Cytoscape 3.6.1 was used to visually upgrade the association network diagram.Results A total of 106 articles that met the inclusion criteria were summarized.SD rats and KM mice were the mostly commonly used animal models of Henoch-Sch?nlein purpura nephritis and most studies used drug-induced models.Bovine serum albumin(BSA)+lipopolysaccharide(LPS)+carbon tetrachloride(CCl4)+castor oil,ovalbumin(OVA)+Freund's complete adjuvant,gliadin+Indian ink,and BSA+staphylococcal enterotoxin B(SEB)were used to produce the animal models,generally with cycles of 5～14 weeks.The standard of modeling was skin purpura and increased numbers of urine red blood cells.Proteinuria,glomerular mesangial hyperplasia in kidney tissue,and immune complex mainly composed of immunoglobulin A(IgA)deposited in small blood vessels indicated successful modeling.There were 36 medical indexes,including 23 indexes related to the kidney and urine and nine indexes related to blood.Among these,10 indexes,such as 24 h urine protein quantification,interleukin,renal pathology,urine red blood cell count,IgA,circulating immune complex and creatinine were used in≥10%of cases.Cluster analysis of high-frequency indicators showed that the comprehensive evaluation model of 24 h urinary protein quantification+interleukin+renal pathology+urinary red blood cell count+IgA was mostly used.Conclusions Most existing animal models of Henoch-Sch?nlein purpura nephritis have used male SD rats or female Kunming mice,and most models were induced by drugs.Among these,the method of stasis-heat syndrome combined with IgA nephropathy(disease-syndrome combination method)has the advantages of good repeatability and a high modeling rate,and may thus provide a reference for the selection of animal experimental models of Henoch-Sch?nlein purpura nephritis.

OBJECTIVE: We aimed to understand the willingness and barriers to the acceptance of tuberculosis (TB) preventive treatment (TPT) among people with latent TB infection (LTBI) in China. METHODS: A multicenter cross-sectional study was conducted from May 18, 2023 to December 31, 2023 across 10 counties in China. According to a national technical guide, we included healthcare workers, students, teachers, and others occupations aged 15-65 years as our research participants. RESULTS: Overall, 17.0% (183/1,077) of participants accepted TPT. There were statistically significant differences in the acceptance rate of TPT among different sexes, ages, educational levels, and occupations ( P < 0.05). The main barriers to TPT acceptance were misconceptions that it had uncertain effects on prevention (57.8%, 517/894), and concerns about side effects (32.7%, 292/894). CONCLUSION An enhanced and comprehensive understanding of LTBI and TPT among people with LTBI is vital to further expand TPT in China. Moreover, targeted policies need to be developed to address barriers faced by different groups of people.

Objective: To evaluate the value of next-generation sequencing (NGS) in the prevention and management of thalassemia. Methods: A systematic search was performed in eight databases including China Biomedical Literature Database, Chinese National Knowledge Infrastructure, Chinese Scientific Journals Database, Wanfang database, PubMed, EMBASE, Web of Science, and Cochrane Library from the inception to 1 June 2022. Stata 17.0 and Review Manager 5.4 were used for the meta-analysis. Results: Nine studies containing 14794 participants were included in the meta-analysis. Compared with the routine genetic testing (including Gap-PCR and reverse dot blot), NGS had higher detection rates in screening thalassemia (RR 1.22, 95% CI 1.13-1.31, P<0.01), particularly for the α-thalassaemia mutation carriers (RR 1.24, 95% CI 1.07-1.44, P<0.01). However, no significant difference was found in the screening of β-thalassemia (RR 1.10, 95% CI 0.99-1.23, P>0.05). Conclusions: Compared with routine genetic testing, NGS had a higher detection rate in general, particularly in the detection of α-thalassemia.

OBJECTIVE: To assess the value of fluorescence in situ hybridization (FISH) technique for the verification of the clonalities of non-clonal cytogenetic abnormalities (n-CCA) identified by conventional chromosome banding analysis (CBA) in patients with Myelodysplastic syndrome (MDS). METHODS: Clinical data and results of karyotyping and FISH assays for 91 patients of MDS with n-CCA identified by CBA were retrospectively analyzed. In total 94 non-clonal +8, 5q-, -7/7q- or 20q- were detected by CBA, among which 43 (45.7%) were verified to be clonal abnormalities by FISH. RESULTS: The detection rates for +8, 5q-, -7/7q- and 20q- by FISH were 47.6% (30/63), 25% (2/8), 41.7% (5/12), 40% (2/5) and 66.7% (4/6), respectively, with the positive cells accounting for 4% to 90% of all counted cells, with a median value of 7%. The 91 patients were divided into three groups including ≥ 20, 10 ~< 20 and < 10 based on the numbers of metaphase cells in CBA, and the detection rates by FISH for the three groups were 43.7% (31/71), 33.3% (3/9) and 63.6% (7/11), respectively, which showed no statistically difference (P > 0.05). Continuous CBA and FISH surveys were conducted for 26 patients who received supportive treatment, and the results revealed that 91.7% (11/12) of FISH-verified positive abnormalities had persisted, whereas 92.9% (13/14) of the n-CCA verified as negative by FISH was transient. CONCLUSION Nearly half of the CBA identified n-CCA have been verified as clonal aberrations by FISH, and the FISH detection rate showed no correlation with the number of metaphase cells. FISH test is strongly recommended for verifying the clonalities of n-CCA detected by CBA, and continuous cytogenetic survey of the patients with MDS is necessary.
