ObjectiveTo observe the clinical effectiveness and safety of Qingfei Shenshi Decoction （清肺渗湿汤） combined with western medicine for patients with bronchial asthma of heat wheezing syndrome， and to explore its potential mechanism of action. MethodsEighty-six participants with bronchial asthma of heat wheezing syndrome were randomly divided into treatment group and control group， each group with 43 participants. The control group received conventional western medicine， and the treatment group was additionally administered Qingfei Shenshi Decoction orally on the basis of the control group， 1 dose per day. Both groups were treated for 14 days. The primary outcome measure was clinical effectiveness； secondary outcome measures included traditional Chinese medicine （TCM） syndrome score， asthma control test （ACT） score， pulmonary function indices such as forced expiratory volume in 1 second （FEV₁）， forced vital capacity （FVC）， peak expiratory flow （PEF）， serum inflammatory factor levels including interleukin-4 （IL-4）， tumour necrosis factor-α （TNF-α）， and high-sensitivity C-reactive protein （hs-CRP）， and immune function indices including CD3⁺， CD4⁺， CD8⁺， CD4⁺/CD8⁺. All outcome measures were evaluated before and after treatment. Vital signs were monitored， and electrocardiography， blood routine， urine routine， liver function， and renal function tests were performed before and after treatment. Adverse events and reactions during the study were recorded. ResultsA total of 80 patients completed the trial with 40 in each group. The total clinical effective rate of the treatment group was 97.5% （39/40）， which was significantly higher than that of the control group （85.0%， 34/40， P＜0.05）. After treatment， both groups showed decreased TCM syndrome scores， IL-4， TNF-α， hs-CRP， and CD8⁺ levels， as well as increased ACT scores， CD3⁺， CD4⁺， CD4⁺/CD8⁺， FEV₁， FVC， and PEF levels （P＜0.05 or P＜0.01）. Moreover， the improvements in these indices were more significant in the treatment group than in the control group （P＜0.05 or P＜0.01）. No significant abnormalities in safety indicators were observed in either group， and no adverse events or reactions occurred. ConclusionQingfei Shenshi Decoction combined with conventional western medicine for patients with bronchial asthma of heat wheezing syndrome can effectively improve the clinical symptoms， pulmonary function， and clinical effectiveness， with good safety. Its mechanism may be related to reducing inflammatory factor levels and regulating T lymphocyte subsets to improve immune function.

OBJECTIVE: To precise classify sacral meningeal cysts, effective guide minimally invasive neurosurgery and postoperative personalized rehabilitation by multiple dimensions radiographic reconstruction MRI. METHODS: From March to December 2021, based on the original 3D-fast imaging employing steadystate acquisition (FIESTA) scanning sequence, 92 patients with sacral meningeal cysts were pre-operatively evaluated by multiple dimensional reconstruction MRI. The shape of nerve root and the leakage of cyst were reconstructed according to the direction of nerve root or leakage track showed on original MRI scans. Sacral canal cysts were accurately classified as including nerve root and without nerve root, so as to accurately design the incision of skin and formulate corresponding open range of the posterior wall of the sacral canal. Under the microscope intraoperation, the shape of the nerve roots inside cysts or leakage track of the cysts without nerve roots were verified and explored. After the reinforcement and shaping operation, several reexaminations of multiple dimensional reconstruction MRI were performed to understand the deformation of the nerve root and hydrops in the operation cavity, so as to formulate a persona-lized rehabilitation plan for the patients. RESULTS: Among the 92 patients with sacral mengingeal cyst, 58 (63.0%) cysts with nerve root cyst, 29 (31.5%) cysts without nerve root cyst, and 5 (5.4%) cysts with mixed sacral canal cyst. In 58 patients with nerve root cysts, the accuracy of preoperative clinical classification on MRI image reached 96.6% (56/58) through confirmation by operating microscope. Only 2 cases of large single cyst with nerve root on the head of cyst were mistaken for without nerve root type. In 29 patients with sacral cyst without nerve root, the accuracy of preoperative image reached 100% through confirmation by operating microscope. The accuracy of judging the internal nerve root and leakage of 12 cases with recurrent sacral cyst was also 100%. Two cases of delayed postoperative hydrops were found one month after operation. After rehabilitation treatment by moxibustion and bathing, the hydrops disappeared 4-6 months after operation. CONCLUSION Multiple dimensional reconstruction MRI can precisely make clinical classification of sacral meningeal cysts before operation, guide minimally invasive neurosurgery effectively, and improve the rehabilitation effect.

This paper summarized Professor ZHOU Zhaoshan's clinical experience in treating bronchial asthma （abbreviated as asthma） by stages with dampness-draining method. It is believed that pathogenic dampness is the key pathological factor in the onset of asthma. Dampness accumulates into water， which gathers into rheum； the condensed rheum forms phlegm， which lingers in the lungs. When external pathogens trigger the latent phlegm， phlegm and qi become mutually obstructed， leading to airway obstruction， disrupted qi movement， and upward reversal of lung qi， thereby resulting in asthma attacks. The treatment emphasizes a stage-based approach. During acute attacks， the main syndromes include cold-damp obstructing the lungs， damp-heat accumulating in the lungs， and shaoyang （少阳） constraint with heat. For the syndrome of cold-damp obstructing the lungs， a self-formulated Wenfei Shenshi Decoction （温肺渗湿汤） is used to warm the lungs and disperse cold， drain dampness and relieve panting； for the syndrome of damp-heat accumulating in the lungs， a self-formulated Qingfei Shenshi Decoction （清肺渗湿汤） is employed to clear the lungs and expel heat， drain dampness and relieve asthma； and for the syndrome of shaoyang constraint with heat， a self-formulated Chaihu Shenshi Decoction （柴胡渗湿汤） is administered to harmonize the shaoyang， clear heat and drain dampness. During the remission stage， treatment is based on the underlying kidney-deficiency constitution， and a self-formulated Bushen Shenshi Decoction （补肾渗湿汤） is formulated to tonify the kidneys and drain dampness， improve qi reception and relieve panting.

OBJECTIVE: To explore the clinical characteristics and gene variant of a fetus with Farber lipogranulomatosis caused by ASAH1 gene variant. METHODS: A fetus with Farber lipogranulomatosis caused by ASAH1 gene variant diagnosed at Women and Children's Hospital of Ningbo University in August 2024 was selected as the subject. Clinical data and abortion tissue samples of the fetus and peripheral blood samples of its parents were collected for whole exome sequencing (WES). Sanger sequencing validation and bioinformatics analysis were performed on candidate variants. This study was approved by Women and Children's Hospital of Ningbo University (Ethics No. EC2020-048). RESULTS: Generalized skin oedema, pericardial effusion, right pleural effusion and increased bowel echogenicity of the fetus were founded by prenatal ultrasound. WES revealed that the fetus has harbored a homozygous c.101C>A (p.Ser34Ter) variation in exon 2 of the ASAH1 gene. Sanger sequencing confirmed that both parents carry the heterozygous nonsense variation c.101C>A (p.Ser34Ter) in ASAH1 gene, which has not been included in databases such as HGMD, ClinVar, 1000 Genomes, ExAC, dbSNP, and gnomAD. Based on the Standards and Guidelines for the Interpretation of Sequence Variants of the American College of Medical Genetics and Genomics (ACMG), the variant was predicted to be pathogenic (PM2_Supporting+PVS1+PM3_Supporting). The AlphaFold3 model protein structure prediction reveals that the c.101C>A variant caused the premature appearance of a termination codon, resulting in only a small partial α-helix structure in the N-terminal of the encoded ASAH1 protein, with the complete loss of the α-helix structure in the core domain, which might lead to the loss of function of this protein. CONCLUSION The c.101C>A (p.Ser34Ter) variant of the ASAH1 gene probably underlay the Farber lipogranulomatosis with hydrops fetalis in this fetus. The newly discovered c.101C>A (p.Ser34Ter) variant has enriched the mutational spectrum of Farber lipogranulomatosis.

OBJECTIVE: To explore the genetic characteristics of a fetus affected with Structural heart defects and renal anomalies syndrome (SHDRA). METHODS: A pedigree with SHDRA (fetus and the parents) who had visited the Affiliated Women and Children's Hospital of Ningbo University in April 2023 was selected as the study subject. Clinical data of the family were collected. A total of 10 mL of amniotic fluid cells from the fetus and 5 mL of peripheral blood samples from the parents were collected for genomic DNA extraction. Trio whole-exome sequencing (Trio-WES) was performed, and Sanger sequencing was used to validate candidate variants in the family. The identified variants were classified according to the Standards and Guidelines for the Interpretation of Sequence Variants established by the American College of Medical Genetics and Genomics (ACMG) (hereinafter referred to as the "ACMG Guidelines). Relevant research literature on SHDRA in domestic and international databases were searched for literature review. This study was approved by the Affiliated Women and Children's Hospital of Ningbo University (Ethics No. EC2023-094). RESULTS: In this family, prenatal ultrasound at 18 weeks of gestation revealed left renal multicystic dysplasia in the fetus. After birth, the infant exhibited an ostium secundum atrial septal defect, patent ductus arteriosus, and left renal multicystic dysplasia. Trio-WES revealed that the fetus had carried c.344dup (p.L116Afs*32) and c.90_104dup (p.Ala31_Ala35dup) compound heterozygous variants in the TMEM260 gene, which were respectively inherited from its father and mother. According to the ACMG guidelines, the c.344dup (p.L116Afs*32) and c.90_104dup (p.Ala31_Ala35dup) variants were classified as pathogenic (PM2_Supporting+PVS1+PP4) and likely pathogenic (PM2_Supporting+PM4+PM3+PP4), respectively. According to the literature search strategy set for this study, a total of 6 literature was retrieved, involving 25 SHDRA patients from 20 families. Together with the patients in this study, there were 14 TMEM260 gene variants, most of which were frameshift variants (7 types) and had located in exons 3, 11 and 13. The main clinical features of SHDRA were congenital heart malformation, renal abnormality and neurodevelopmental abnormality, and there was a lack of genotype-phenotype correlation. CONCLUSION The c.344dup (p.L116Afs*32) and c.90_104dup (p.Ala31_Ala35dup) variants of the TMEM260 gene probably underlay the SHDRA in this family. Above finding has provided a basis for clinical diagnosis and genetic counseling for the family.

OBJECTIVE: To explore the genetic etiology of a child with Brain small vessel disease 1 with ocular anomalies. METHODS: A child who was admitted to Ningbo Women and Children's Hospital on May 28, 2022 was selected for the study. Clinical data were collected, and peripheral blood samples from the child and her parents were obtained for genomic DNA extraction. Whole exome sequencing (WES) was performed to screen for pathogenic variants. Candidate variants were validated via Sanger sequencing and subjected to bioinformatic analysis. This study was approved by the Medical Ethics Committee of Ningbo Women and Children's Hospital (Ethics No. EC2020-014). RESULTS: The child was a 7-year-old female with a diagnosis of epilepsy. WES revealed that she has carried a heterozygous missense variant in the COL4A1 gene: c.1792G>A (p.Gly598Ser). Sanger sequencing confirmed that her parents both had the wild-type genotype for this variant. Based on American College of Medical Genetics and Genomics (ACMG) Standards and Guidelines for the Interpretation of Sequence Variants, the variant were predicted to be a likely pathogenic (PS2+PM1+PM2_Supporting+PP3). Bioinformatics predicted that amino acid 598 was highly conserved in different species, formed hydrogen bond with Asp599 after becoming Ser598. CONCLUSION The heterozygous missense variant of the COL4A1 gene c.1792T>C (p.G598S) could be the pathogenic cause of this child with Brain small vessel disease 1 with ocular anomalies.

OBJECTIVE: To explore the clinical characteristics and genetic etiology of a patient with Fliedner-Zweier syndrome (FZS). METHODS: A pregnant woman who was diagnosed with FZS at the Affiliated Women and Children's Hospital of Ningbo University in November 2023 for "intellectual disability, epilepsy, delayed language development and facial abnormalities" was selected as the study subject. Peripheral blood samples were collected from the woman and her husband, whilst amniotic fluid sample was obtained from the fetus. Following extraction of genomic DNA, whole-exome sequencing (WES) and chromosomal karyotyping analysis were performed. Candidate variant was validated by Sanger sequencing. Pathogenicity of the variant was classified based on the guidelines from the American College of Medical Genetics and Genomics (ACMG). This study was approved by the Medical Ethics Committee of the hospital (Ethics No.: EC2023-094). RESULTS: The proband, a 23-year-old woman, was at 19⁺² weeks of gestation and had a history of epilepsy, mild intellectual disability, delayed language development, and subtle facial dysmorphism. Chromosomal analysis showed the she has a normal karyotype. WES revealed that the woman and her fetus both harbored a heterozygous c.1489C>T (p.Gln497Ter) nonsense variant of the SCAF4 gene, which was verified by Sanger sequencing as de novo. Based on the ACMG guidelines, the variant was classified as pathogenic (PVS1+PM2_supporting+PS2_supporting). According to pre-set search strategy, five articles were retrieved. Together with the patient in this study, a total of 69 FZS patients were involved (including 7 from China). The main clinical features have included intellectual disability, epilepsy, behavioral abnormalities, and facial dysmorphism. CONCLUSION The heterozygous c.1489C>T (p.Gln497Ter) variant of the SCAF4 gene probably underlyay the FZS in this patient. Above finding has expanded the mutational spectrum of the SCAF4 gene.

OBJECTIVE: To explore the clinical characteristics and genetic etiology of STISS syndrome (an autosomal dominant disorder characterized by ubiquitin-proteasome system dysfunction) in a child. METHODS: A child with STISS syndrome diagnosed at the Affiliated Women and Children's Hospital of Ningbo University in September 2024 due to "abnormal development of external genitalia" was selected as the study subject. Clinical data were retrospectively collected. Peripheral blood samples were obtained from the child and his family members. Following genomic DNA extraction, whole-exome sequencing (WES) and Sanger sequencing validation were carried out. Pathogenicity of the candidate variants was assessed based on the guidelines from American College of Medical Genetics and Genomics (ACMG). The study was approved by the Ethics Committee of the hospital (Ethics No.: EC2023-094). RESULTS: The proband, a 16-year-old boy, presented with micropenis, testicular hypoplasia, delayed sexual development, insulin resistance, diabetes mellitus, and obesity. WES revealed that he has harbored a c.934del; p.Met312TrpfsTer3 frameshifting variant of the PSMD12 gene, which was unreported previously. Sanger sequencing confirmed that the variant to be de novo in origin. Based on the guidelines from the ACMG, the variant was classified as pathogenic (PVS1+PM2_supporting+PM6_supporting). The variant was predicted to result in a premature termination codon. Bioinformatics analysis suggested that the amino acid at position 312 is highly conserved, and the variant may therefore affect the protein structure. CONCLUSION Patients with STISS syndrome exhibit clinical features including psychomotor retardation, intellectual disability, distinctive facial features, and urogenital abnormalities. The c.934del (p.Met312TrpfsTer3) frameshift variant of the PSMD12 gene probably underlay the pathogenesis in the proband. Above finding has enriched the mutational spectrum of the PSMD12 gene.

Objective:To investigate the current situation of the use of transjugular intrahepatic portosystemic shunt (TIPS) for portal hypertension, which should aid the development of TIPS in China.Methods:The China Portal Hypertension Alliance (CHESS) initiated this study that comprehensively investigated the basic situation of TIPS for portal hypertension in China through network research. The survey included the following: the number of surgical cases, main indications, the development of Early-TIPS, TIPS for portal vein cavernous transformation, collateral circulation embolization, intraoperative portal pressure gradient measurement, commonly used stent types, conventional anticoagulation and time, postoperative follow-up, obstacles, and the application of domestic instruments.Results:According to the survey, a total of 13 527 TIPS operations were carried out in 545 hospitals participating in the survey in 2021, and 94.1% of the hospital had the habit of routine follow-up after TIPS. Most hospitals believed that the main indications of TIPS were the control of acute bleeding (42.6%) and the prevention of rebleeding (40.7%). 48.1% of the teams carried out early or priority TIPS, 53.0% of the teams carried out TIPS for the cavernous transformation of the portal vein, and 81.0% chose routine embolization of collateral circulation during operation. Most of them used coils and biological glue as embolic materials, and 78.5% of the team routinely performed intraoperative portal pressure gradient measurements. In selecting TIPS stents, 57.1% of the hospitals woulel choose Viator-specific stents, 57.2% woulel choose conventional anticoagulation after TIPS, and the duration of anticoagulation was between 3-6 months (55.4%). The limitation of TIPS surgery was mainly due to cost (72.3%) and insufficient understanding of doctors in related departments (77.4%). Most teams accepted the domestic instruments used in TIPS (92.7%).Conclusions:This survey shows that TIPS treatment is an essential part of treating portal hypertension in China. The total number of TIPS cases is far from that of patients with portal hypertension. In the future, it is still necessary to popularize TIPS technology and further standardize surgical indications, routine operations, and instrument application.

ObjectiveThis paper aims to analyze the clinical characteristics and medication rationality of liver injury related to Epimedii Folium preparation （EP） and explore the possible risk factors of liver injury， so as to provide a reference for the safe clinical application of Epimedii Folium （EF）. MethodA retrospective analysis was conducted on liver injury cases related to EP from 2012 to 2016. ResultThe number of reported liver injury cases and the proportion of severe cases related to the use of EP show an increasing trend， indicating the objective existence of liver injury caused by EP. There are more cases of liver injury related to EP in women than in men， with an onset age range of 15-91 years old and a median onset age of 60 years old （median onset ages for men and women are 59 and 60 years old， respectively）. The time span from taking EP alone to the occurrence of liver injury is 1-386 days， with a median of 38 days. The time span from taking both EP and Western medicine to the occurrence of liver injury is 1-794 days， with a median of 34 days. EF-related liver injury preparations are mostly composed of traditional Chinese medicines that promote immunity and tonify the liver and kidney， indicating that immune stress in the body may be the mechanism of liver injury caused by the use of EP alone or in combination. There is no increasing trend of toxicity with time or dose in the liver injury caused by EP. By further exploring its risk factors， it is found that patients have unreasonable medication methods such as excessive dosage， repeated use， and multi-drug combination， which may also be one of the important risk factors for EF-related liver injury. ConclusionEP has a certain risk of liver injury and should be emphasized in clinical diagnosis and treatment. Immune stress may be the mechanism of liver injury caused by EP， and in clinical use， it is necessary to be vigilant about the risk of liver injury caused by unreasonable use and combined use with Western medicine.
