ObjectiveTo systematically explore the underlying mechanisms of Huashi Baidu prescription （HBP） against myocardial injury through a multidimensional network analysis of "transcriptome-putative target-phenotype gene". MethodPutative targets of compounds in HBP were predicted using the Encyclopedia of Traditional Chinese Medicine （ETCM 2.0，http：//www.tcmip.cn/ETCM2/front/） and the Integrative Pharmacology-based Research Platform of Traditional Chinese Medicine （TCMIP v2.0，http：//www.tcmip.cn/TCMIP/index.php/Home/Login/login.html）. Clinical predominant symptom phenotypes for HBP against coronavirus disease 2019 （COVID-19） were collected from CNKI and PubMed databases， while clinical side effects of doxorubicin were gathered from the CTD database. Phenotype-related genes were collected from the HPO database and SoFDA data platform （http：//www.tcmip.cn/Syndrome/front/#/）. An interaction network of "transcriptome-putative target-phenotype gene" was constructed. Key nodes were identified through topological feature calculations， and functional enrichment analysis was conducted to explain the underlying mechanism. Pharmacodynamic evaluation and mechanism verification were performed using a doxorubicin-induced myocardial injury mouse model. Sixty-five SPF-grade C57BL/6J male mice were randomly divided into a control group， a doxorubicin model group， and low-， medium-， and high-dose HBP groups （HBP-L/M/H）， with 13 mice per group. Histopathological severity was assessed using hematoxylin-eosin （HE） and Masson staining. Fibrosis markers were measured by Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR）， and protein expression was detected by Western blot. ResultA total of 1 044 putative targets for HBP were obtained from ETCM 2.0 and TCMIP v2.0. From the CTD， HPO， and SoFDA databases， 1 223 potential effect-related targets were identified. Cardiac transcriptome sequencing （RNA-seq） yielded 214 genes related to doxorubicin-induced myocardial injury and 58 genes associated with the effects of HBP， using criteria of P-value<0.05 and FC > 1.5/< 0.667. Analysis of the multidimensional molecular network revealed that the mechanisms of HBP on myocardial injury were mainly related to immune-inflammation imbalance， cellular metabolism， myocardial cell function and fibrosis， angiogenesis， contraction and platelet activation， DNA synthesis， metabolism and repair， as well as cell death and oxidative stress. HBP improved cardiovascular abnormalities such as reduced ejection fraction， myocardial fibrosis， myocarditis， hypertriglyceridemia， and arterial/venous thrombosis. Animal experiments demonstrated that HBP reduced the abnormal high expression of Nod-like receptor heat protein domain Protein 3 （NLRP3）， Caspase-1， apoptosis-associated speck-like protein （ASC）， and Gasdermin D （GSDMD） in myocardial tissue induced by doxorubicin （P<0.05）， and improved the elevated mRNA levels of fibrosis markers transforming growth factor-β₁ （TGF-β₁）， Smad3， and α-smooth muscle actin （α-SMA） （P<0.05）. ConclusionHBP can improve myocardial injury through multiple components， targets， and effects， with the inhibition of the NLRP3 inflammasome activation pathway being a key pharmacodynamic mechanism. This study is expected to provide new insights for the development of targeted therapeutic drugs.

This paper summarized Professor YE Jianzhou's experience in treating atopic dermatitis （AD） in children with the method of regulating the heart and treating the spirit. According to the clinical manifestations of itching-sleep psychological disorders in children with AD， and the physiological characteristics of "heart qi is prone to hyperactivity" and "liver qi is prone to hyperactivity" in children， it is believed that heart and spirit disharmony is an important pathogenesis of AD in children.From the concept of holism in traditional Chinese medicine， the principle of regulating the heart and treating the spirit has been proposed for treatment of AD in children， which is based on the theory of "the five zang （脏） organs store the spirit". In the acute stage， it is recommended to clear the heart， drain fire and calm the spirit with self-made Qingxin Ningshen Decoction （清心宁神汤） in modifications. In the chronic stage， the method of nourishing the heart， unblocking the meridians and calming the spirit is recommended， by using self-made Yangxin Anshen Decoction （养心安神汤） with modifications. The method to tranquilize the heart， subdue yang and contain the spirit should be implemented throughout the entire treatment， and yang-subduing and spirit-containing medicinals such as Duanlonggu （Os Draconis Praeparatum）， Duanmuli （Concha Ostreae Praeparatum） and Zhenzhumu （Concha Margaritiferae Usta） are usually used to treat the body and the spirit simultaneously. All these are offered to provide new ideas for the individualized treatment of children with AD.

ObjectiveTo investigate the potential mechanisms of Jiawei Jingqin Decoction （加味荆芩汤） in the treatment of rosacea. MethodsFifty 8-week-old female BALB/c mice were randomly divided into normal control group， model group， and Jiawei Jingqin Decoction low， medium， and high-dose groups， with 10 mice in each group. Except for the normal control group， mice in the other groups were injected with 40μl of antimicrobial peptide LL-37 at a concentration of 320 μmol/L on the back， repeated once every 12 hours for a total of 4 injections， to induce the rosacea mouse model. The mice in the normal control group were injected with 40 μl of PBS solution at the same time. After successful modeling， the mice in the Jiawei Jingqin Decoction low， medium， and high-dose groups were orally administered Jiawei Jingqin Decoction at doses of 4.35， 8.71， and 17.42 g/（kg·d） respectively， while the mice in the normal control group and the model group were orally administered 20 ml/（kg·d） of normal saline. All groups were treated once daily for 5 days. The changes in skin lesions were observed， and the erythema area was measured and scored. Skin tissue at the injection site was collected for histopathological examination using HE staining， and the number of mast cells was detected using toluidine blue staining. The levels of interleukin-6 （IL-6）， interleukin-1β （IL-1β）， and tumor necrosis factor-alpha （TNF-α） in the skin lesion tissues were measured using the ELISA method. The mRNA expression levels of key factors in the innate immune response pathway of rosacea disease mechanism， including Toll-like receptor 2 （TLR2）， downstream molecules serine protease kallikrein 5 （KLK5） and matrix metalloproteinase 9 （MMP-9）， as well as related inflammatory factors （IL-1β， IL-6， TNF-α）， and adaptive immune CD4⁺ T cell-related factors interferon-gamma （INF-γ） mRNA were detected using RT-qPCR. Immunohistochemical staining was performed to detect the protein expression of KLK5， MMP-9， and the number of CD4⁺ T-positive cells. Western blot analysis was used to determine the protein expression levels of CD4⁺ T cell-related factors including IFN-γ， CC chemokine receptor 5 （CCR5）， signal transducer and activator of transcription 1 （STAT1）， signal transducer and activator of transcription 3 （STAT3）. ResultsThe skin at the injection site on the back of mice in the normal control group appeared normal without any skin lesions or erythema， and histopathological examination showed no infiltration of inflammatory cells. The model group had significantly higher erythema scores and larger erythema areas compared to the normal control group （P＜0.05）， and histopathological examination revealed a significant infiltration of inflammatory cells， with some signs of deep connective tissue damage. Compared to the model group， the Jiawei Jingqin Decoction medium and high-dose groups showed a significant decrease in erythema scores and erythema areas （P＜0.05）， as well as a reduction in inflammatory exudates and inflammatory cell infiltration. However， the Jiawei Jingqin Decoction low-dose group did not show significant difference （P＞0.05）， but there was a slight reduction in inflammatory cell infiltration compared to the model group. When compared to the normal control group， the rosacea skin tissues of the model group showed an increase in the number of mast cells， levels of IL-1β， IL-6， TNF-α， mRNA expression of IL-1β， IL-6， TNF-α， TLR2， INF-γ， KLK5， MMP-9， protein expression of KLK5， MMP-9， and the number of CD4⁺ T-positive cells （P＜0.05）. Compared to the model group， the Jiawei Jingqin Decoction medium and high-dose groups showed a decrease in the number of mast cells， levels of IL-1β， mRNA expression of IL-1β， TNF-α， and the number of CD4⁺ T-positive cells. The Jiawei Jingqin Decoction high-dose group showed a decrease in IL-6， TNF-α levels， mRNA expression of IL-6， TLR2， INF-γ， MMP-9， protein expression of MMP-9， KLK5， and the number of CD4⁺ T-positive cells， as well as a decrease in IFN-γ and STAT1 protein expression （P＜0.05） compared to the Model group. ConclusionJiawei Jingqin Decoction has significant improvement effect on the skin symptoms of roseacne in a mouse model. Its mechanism might be related to regulating skin immune inflammatory reactions， thereby reducing the release of pathogenic factors and inflammatory factors.

Objective:To explore the clinical efficacy of 125I seeds implantation in treating cancer-induced pain and motor dysfunction caused by brachial plexus compression through neurophysiological monitoring. Methods:A retrospective study was conducted on 8 patients (4 males, 4 females; age 58-63 years) who underwent 125I seeds therapy for cancer-induced brachial plexus injury at Hebei Provincial People′s Hospital from January 2021 to August 2023. Pain severity was assessed by using the numerical rating scale (NRS) and motor function was evaluated by using the Fugl-Meyer (F-M) assessment. Electrophysiological monitoring was used to assess changes in sensory and motor branch conduction velocity (CV) of the musculocutaneous nerve, axillary nerve, median nerve, ulnar nerve, and radial nerve before and 3 months after treatment. Paired t-test was used for data analysis. Results:All 8 patients had moderate to severe pain (6 had motor dysfunction). The preoperative and postoperative NRS scores was 5.9±1.0 and 3.3±1.7, respectively ( t=4.93, P=0.002), while F-M scores was 44.8±7.6 and 54.8±5.7, respectively ( t=-3.52, P=0.017). Electrophysiological results showed that 7 patients had lesion involvement in the lower trunk of the brachial plexus, and 1 patient had involvement in the upper trunk. The preoperative and postoperative motor branch CV of the ulnar nerve was (47.2±2.6) and (59.7±8.2) m/s, respectively ( t=-3.17, P=0.034), while the sensory branch CV was (41.8±1.2) and (56.0±5.7) m/s, respectively ( t=-5.82, P=0.001). The nerve CV increased compared to the preoperative ones. Conclusions:125I seeds implantation has good clinical efficacy in treating cancer-related pain and motor dysfunction caused by brachial plexus compression. Changes in electrophysiology can quantitatively monitor the recovery of sensory and motor functions of the brachial plexus.

AIM:To clarify the effect of macrophage PKM2 deficiency on mucosal repair in ulcerative colitis(UC).METHODS:The gene expression and metabolic profiles in UC patients were first analyzed based on the following databases:PXD001608,GSE193677,and GSE214695.Using the macrophage-specific PKM2 elimination mice(PKM2ΔMAC),the functions of PKM2 in dextran sulfate sodium(DSS)-induced UC were clarified in vivo by analyzing the body weight,disease activity index(DAI)scores,HE staining,immunohistochemical staining,and expression of muco-sal barrier markers.The impact of PKM2 on macrophage polarization was also investigated by flow cytometry,RNA se-quencing and RT-qPCR in mouse bone marrow-derived macrophages(BMDMs)and THP-1 cells in vitro.RESULTS:Bioinformatic analysis suggested that the intestinal tissues of UC patients preferred glycolysis.The expression of PKM was parallel to the severity of UC in patients,and the expression of PKM2,but not PKM1,was elevated in macrophages of UC mice.In the DSS-induced UC mice,macrophage-specific PKM2 elimination significantly alleviates the body weight loss,diarrhea,rectal bleeding,colonic shorten,as well as decreased DAI scores and mucosal tissue damage.The BMDMs de-rived from the PKM2ΔMAC mice preferred the M2 polarization upon LPS or IL-4 stimulation to that derived from the wild-type mice,as indicated by the F4/80+CD45+CD86+and F4/80+CD45+CD206+population,as well as the expression of Ocln,F11r and Tjp-1.The RNA sequencing results indicated significant gene differential expression in PKM2 knockout mouse macrophages,which was enriched in biological processes such as leukocyte migration,tissue remodeling,and cytokine in-teractions.Macrophage PKM2 deficiency promoted the expression of mucosal repair factors(Il8,Cxcl1,Ptgs2 and Wnt6),which was further validated in PKM2 knockout THP-1 cells.CONCLUSION:The PKM2 deficiency in macro-phages benifits the mucosal repair in UC status via facilitating the wound-healing macrophage polarization.

OBJECTIVE: To explore the characteristics of copy number variation (CNV) within the Y chromosome azoospermia factor (AZF) region in patients with spermatogenesis disorders in the Shenzhen area. METHODS: A total of 123 patients with spermatogenesis disorders who had visited Shenzhen People's Hospital from January 2016 to October 2022 (including 73 patients with azoospermia and 50 patients with oligozoospermia) and 100 normal semen males were selected as the study subjects. The AZF region was detected with multiplex ligation-dependent probe amplification (MLPA), and the correlation between the CNV in the AZF region and spermatogenesis disorders was analyzed using the chi-square test or Fisher's exact test. RESULTS: 19 CNV were detected among 53 patients from the 223 samples, including 20 cases (27.40%, 20/73) from the azoospermia group, 19 cases (38%, 19/50) from the oligozoospermia group, and 14 cases (14%, 14/100) from the normal control group. In the azoospermia, oligozoospermia, and normal control groups, the detection rates for CNV related to the AZFa region (including AZFab and AZFabc) were 5.48% (4/73), 2.00% (1/50), and 0 (0/100), respectively. The detection rates for the AZFb region (including the AZFbc region) were 6.85% (5/73), 0 (0/50), and 0 (0/100), respectively. The detection rates for gr/gr deletions in the AZFc region were 2.74% (2/73), 6.00% (3/50), and 9.00% (9/100), respectively, and those for b2/b4 deletions in the AZFc region were 2.74% (2/73), 10.00% (5/50), and 0 (0/100), respectively. The detection rates for complex rearrangements in the AZFc region were 6.85% (5/73), 18.00% (9/50), and 3.00% (3/100), respectively. Statistical analysis showed no significant difference in the detection rate of gr/gr deletions between the three groups (Fisher's Exact Test value = 2.712, P = 0.249); the differences in the detection rate of b2/b4 deletions between the three groups were statistically significant (Fisher's Exact Test value = 9.489, P = 0.002); the differences in the detection rate of complex rearrangements in the AZFc region between the three groups were statistically significant (Fisher's Exact Test value = 9.493, P = 0.006). In this study, a rare AZFa region ARSLP1 gene deletion (involving SY86 deletion) was detected in a patient with oligozoospermia. CONCLUSION CNV in the AZFa and AZFb regions have a severe impact on spermatogenesis, but partial deletion in the AZFa region (ARSLP1 gene deletion) has a minor impact on spermatogenesis. The b2/b4 deletion and complex rearrangement in the AZFc region may be risk factors for male infertility. The gr/gr deletion may not serve as a risk factor for male infertility in the Shenzhen area.

OBJECTIVE: To carry out prenatal diagnosis and genetic analysis for a fetus with disorders of sex development (DSDs). METHODS: A fetus with DSDs who was identified at the Shenzhen People's Hospital in September 2021 was selected as the study subject. Combined molecular genetic techniques including quantitative fluorescence PCR (QF-PCR), multiplex ligation-dependent probe amplification (MLPA), chromosomal microarray analysis (CMA), quantitative real-time PCR (qPCR), as well as cytogenetic techniques such as karyotyping analysis and fluorescence in situ hybridization (FISH) were applied. Ultrasonography was used to observe the phenotype of sex development. RESULTS: Molecular genetic testing suggested that the fetus had mosaicism of Yq11.222qter deletion and X monosomy. Combined with the result of cytogenetic testing, its karyotype was determined as mos 45,X[34]/46,X,del(Y)(q11.222)[61]/47,X,del(Y)(q11.222),del(Y)(q11.222)[5]. Ultrasound examination suggested hypospadia, which was confirmed after elective abortion. Combined the results of genetic testing and phenotypic analysis, the fetus was ultimately diagnosed with DSDs. CONCLUSION This study has applied a variety of genetic techniques and ultrasonography to diagnose a fetus with DSDs with a complex karyotype.

Objective:To evaluate early left ventricular myocardial work in patients with metabolic syndrome (MS) by pressure-strain loops (PSL).Methods:From September 2020 to April 2021, 70 MS patients in the First Hospital of Qinhuangdao Affiliated to Hebei Medical University without left ventricular remodeling were selected as MS group and 65 normal controls as control group, PSL was used to obtain the myocardial power parameters, including global work index (GWI), global work efficiency (GWE), global constructive work (GCW) and global wasted work (GWW). The changes of the parameters were compared between the two groups and their correlations with biochemical parameters were performed in MS group.Results:The left ventricular global longitudinal strain (GLS), GWI, GCW and GWE in MS group were lower than those in normal group, while GWW was higher than that in normal group ( P<0.05). Pearson correlation analysis showed that GWI was positively correlated with high-density lipoprotein cholesterol (HDL-C) ( r=0.194, P<0.05), and negatively correlated with diastolic blood pressure (DBP), waist circumference (WC), fasting blood glucose (Glu), triglyceride (TG) and GLS ( r=-0.257, -0.452, -0.239, -0.193, -0.758, all P<0.05). GWE was negatively correlated with SBP, DBP, WC, Glu, TG and GLS ( r=-0.360, -0.269, -0.326, -0.352, -0.265, -0.663, all P<0.01), and positively correlated with HDL-C ( r=0.201, P<0.05). GCW was negatively correlated with WC and GLS ( r=-0.299, -0.737; all P<0.001). GWW was positively correlated with SBP, DBP, WC, Glu, TG and GLS ( r=0.435, 0.308, 0.413, 0.547, 0.272, 0.400, all P<0.01), and negatively correlated with HDL-C ( r=-0.336, P<0.001). Conclusions:PSL can quantitatively evaluate the changes of early myocardial work in MS patients with good repeatability and has certain clinical value.

OBJECTIVE: To perform prenatal diagnosis, pedigree analysis, and genetic counseling of a pregnant woman who gave birth to a child with Kleefstra syndrome. METHODS: Karyotype analysis, chromosomal microarray analysis (CMA), multiplex ligation-dependent probe amplification (MLPA) and fluorescence in situ hybridization (FISH) were used of peripheral blood and amniotic fluid to find causes. Recurrence risk assessment was performed later. RESULTS: The amniotic fluid sample showed a 9q34.3 microduplication of arr (hg19) 9q34.3 (140 168 806-141 020 389)× 3, which overlapped the 9q34.3 microdeletion region of proband. The pregnant woman was detected with a balanced translocation of ish, t(9;17)(9q34.3; qter) (9p+; 17p+,9q+, 17q+). No other abnormal results were found in the family. CONCLUSION Offspring who share the same chromosome segment deletion or duplication are always from parent who carries balanced chromosomal structural aberration.
