Superior vena cava syndrome(SVCS)is a group of clinical syndromes caused by obstruction of the superior vena cava and its major branches from various causes.Pulmonary artery stenosis(PS)is a complication of lung cancer or mediastinal tumours.SVCS combined with PS due to pulmonary metastases from bladder cancer is extremely rare and has not been reported in the literature.Here we reported an old male patient with pulmonary metastases from bladder cancer presenting with swelling of the head,neck and both upper limbs.SVCS combined with PS was clarified by pulmonary artery computed tomography angiography(CTA)and digital subtraction angiography(DSA).Endovascular stenting was used to treat SVCS.Angiography also showed that PS had not caused pulmonary hypertension and did not need to be treated.The swelling of the patient's head,neck and upper limbs was gradually reduced after the procedure.

The emergence and evolution of digital intelligent technology has profoundly influenced the development of minimally invasive research-oriented hepatobiliary and pancreatic surgery discipline. Over various periods, our team has always adhered to the principle of "being oriented by clinical issues and driven by clinical needs", continuously carried out innovative research across interdisciplinary boundaries, propelling the evolution of digital intelligent technology. Spanning over two decades, this journey includes the progression from digital virtual human, three-dimensional visualization, molecular fluorescence imaging, augmented reality and mixed reality, artificial intelligence, to the realm of human visualization meta-universe. This evolution facilitates the shift from two-dimensional empirical diagnoses of hepatobiliary and pancreatic surgical diseases to deep learning intelligent diagnostics, the transition from morphology-based tumor diagnoses to molecular imaging-based diagnostics, and from conventional empirical surgery to intelligent navigation surgery. The authors provide a comprehensive review of our developmental process and achievements within the realm of digital intelligent diagnostic and therapeutic technologies, with the aims to promote the development and application of digital intelligent medicine.

The key pathogenesis of coronary heart disease （CHD） is spleen deficiency and phlegm stasis， and dysfunctional high-density lipoprotein （dys-HDL） may be the biological basis for the occurrence of CHD due to spleen deficiency and phlegm stasis. Considering the biological properties and effects of high-density lipoprotein （HDL）， it is believed that the structure and components of HDL are abnormal in the state of spleen deficiency which led to dys-HDL； and dys-HDL contributes to the formation of atherosclerotic plaques through two major pathways， namely， mediating the dysfunction of endothelial cells and mediating the foaminess of macrophages and smooth muscle cells， thus triggering the development of CHD. It is also believed that dys-HDL is a microcosmic manifestation and a pathological product of spleen deficiency， and spleen deficiency makes foundation for the production of dys-HDL； dys-HDL is also an important biological basis for the phlegm-stasis interactions in CHD. The method of fortifying spleen， resolving phlegm， and dispelling stasis， is proposed as an important principle in the treatment of CHD by traditional Chinese medicine， which can achieve the therapeutic purpose by affecting the changes in the structure and components of dys-HDL， thus revealing the scientific connotation of this method， and providing ideas for the diagnosis and treatment of CHD by traditional Chinese medicine.

Objective To observe the influence of felodipine sustained release tablets combined with atorvastatin calcium tablets on electrocardiogram indicators and vascular endothelial function in elderly patients with coronary heart disease(CHD)complicated with angina pectoris(AP).Methods According to cohort methods,elderly patients with CHD and AP were divided into control group(oral administration of atorvastatin calcium tablets,20 mg every time)and treatment group(combined with felodipine sustained release tablets on the basis of control group,with initial dose of 5 mg,and then gradually adjusted to 10 mg each time).The 2 groups were treated for 3 months.The electrocardiogram indicators,vascular endothelial function,blood lipids,inflammatory factors and adverse drug reactionswere compared between groups.Results Sixty cases were enrolled in each group.After 3 months of treatment,the QT interval dispersion(QTd)in treatment group and control group were(37.38±4.25)and(42.05±4.74)ms,the corrected QT interval dispersion(QTcd)values were(38.53±4.66)and(43.78±4.87)ms,the QRS duration limits were(92.13±6.29)and(98.79±6.31)ms,serum nitric oxide(NO)levels were(81.31±5.68)and(77.08±4.94)μmol·L-1,endothelin-1(ET-1)were(51.87±3.48)and(56.19±3.53)pg·mL-1,interleukin(IL)-6 levels were(9.17±1.48)and(11.42±2.13)pg·mL-1,vascular cell adhesion molecule(VCAM-1)levels were(120.51±12.45)and(133.76±13.64)pg·mL-1,C-reactive protein(CRP)levels were(0.95±0.11)and(1.08±0.14)pg·mL-1,respectively,with slalistically significanl dillerence(all P＜0.05).After treatment,the total cholesterol levels in treatment group and control group were(3.65±0.47)and(3.81±0.51)mmol·L-1,triglyceride levels were(1.65±0.28)and(1.71±0.33)mmol·L-1,low density lipoprotein cholesterol levels were(2.34±0.31)and(2.45±0.39)mmol·L-1,respectively,without statistically significant diference between the 2 groups(all P＞0.05).During treatment,the incidence rates of adverse reactions in treatment group and control group were 10.00％(6 cases/60 cases)and 6.67％(4 cases/60 cases)respectively,without statistically significant diference between the groups(P＞0.05).Conclusion Felodipine sustained release tablets combined with atorvastatin calcium tablets can effectively improve the electrocardiogram indicators of elderly patients with CHD and AP,reduce inflammatory factors levels and blood lipids levels,and improve the vascular endothelial function,and has good safety.

Objective:To explore the association between frailty index (FI) and the risk for cardiovascular disease (CVD) in adults in Inner Mongolia Autonomous Region, and provide new evidence for the prevention of CVD in adults in Inner Mongolia Autonomous Region.Methods:The FI was constructed by using the data from a prospective cohort with a sample size of 25 055 individuals in 6 years of follow-up, and the prevalence of frailty in adults in Inner Mongolia Autonomous Region was described by the FI, and Cox proportional hazard regression model was used to evaluate the association between the FI and the incidence of CVD in adults in Inner Mongolia Autonomous Region.Results:The FI of the study population was 0.24±0.09. The population in the pre-frail (FI: 0.21-0.27) and frail (FI≥0.28) phases had increased risk for CVD compared to non-frail (FI≤0.20) population [pre-frail: hazard ratio ( HR)=1.232, 95% CI: 1.127-1.347; frail phase: HR=1.418, 95% CI:1.299-1.548]. For every 0.10 increase in FI, the risk for cardiovascular disease increased by 20.3% ( HR=1.203,95% CI:1.156-1.252). Conclusions:In this study, we constructed a FI, which can suggest the risk for CVD. As the increase of frailty degree, the risk for CVD increases.

Objective To observe the effects of abdominal penetrating moxibustion combined with acupuncture at the"four chong points"on balance,walking function and trunk control in patients recovering from stroke.Methods Seventy-eight patients recovering from stroke were randomly divided into an observation group and a control group,with 39 patients in each group.The control group was given conventional rehabilitation exercises,while the observation group was given abdominal penetrating moxibustion combined with acupuncture at the"four chong points"on the basis of the control group.Both groups were treated for 2 consecutive months.After 2 months of treatment,the clinical efficacy of the two groups was evaluated,and the changes in the Berg Scale score and the Timed Up and Go Test(TUGT)were observed before and after treatment.The changes in the National Institutes of Health Stroke Scale(NIHSS)scores were compared before and after treatment between the two groups.The Sheikh Trunk Control Scale scores were also evaluated.Results(1)The total effective rate of the observation group was 94.87%(37/39),and the total effective rate of the control group was 80.00%(31/39),and the efficacy of the observation group was superior to that of the control group,and the difference was statistically significant(P＜0.05).(2)After treatment,the Berg scores of the patients in the two groups were significantly increased(P＜0.05),and the Berg scores of the observation group were higher than those of the control group,and the difference was statistically significant(P＜0.05).(3)After treatment,the TUGT time and NIHSS score of patients in the two groups were significantly improved(P＜0.05),and the TUGT time of the observation group was shorter than that of the control group,and the NIHSS score was lower than that of the control group,and the difference was statistically significant(P＜0.05).(4)After treatment,the Sheikh trunk control scores of the two groups were significantly increased(P＜0.05),and the Sheikh trunk control score of the observation group was higher than that of the control group,and the difference was statistically significant(P＜0.05).Conclusion Abdominal penetrating moxibustion method combined with acupuncture at the four chong points for the treatment of stroke recovery can effectively restore the patients'balance and walking function,improve the patients'trunk control ability,and the therapeutic effect is precise.

Objective:To carry out genetic testing on a child diagnosed with Very-long-chain acyl-CoA dehydrogenase deficiency (VLADD) in order to provide a basis for genetic counseling and prenatal diagnosis for his family.Methods:Whole exome sequencing was performed for the proband. Candidate variant sites in the ACADVL gene were verified by Sanger sequencing, and their pathogenicity was predicted based on the guidelines from the American College of Medical Genetics and Genomics (ACMG). Prenatal diagnosis was performed on the fetus upon subsequent pregnancy. This study was approved by Medical Ethics Committe of the Luoyang Maternal and Child Health Care Hospital (Ethics No.LYFY-YCCZ-2021003). Results:The proband was found to harbor compound heterozygous variants of the ACADVL gene, namely c. 1532G>A and 1827+ 2_1827+ 12del, which were inherited from his mother and father, and classified as likely pathogenic and pathogenic, respectively. By combining the clinical manifestations of the proband and the results of blood tandem mass spectrometry and genetic testing, the child was ultimately diagnosed as cardiomyopathy type VLADD. Prenatal diagnosis showed that the fetus has carried the same compound heterozygous variants, and the couple had opted to terminate the pregnancy. Conclusion:The c. 1532G>A/1827+ 2_1827+ 12del compound heterozygous variants of the ACADVL gene probably underlay the pathogenesis of VLADD in this pedigree. The discovery of the 1827+ 2_1827+ 12del variant has enriched the mutational spectrum of the ACADVL gene.

Objective:To summarize the clinical manifestations of Autosomal dominant complex neurodevelopmental disorders due to variants of EEF1A2 gene and explore their pathogenic mechanisms. Methods:A child who had visited Luoyang Maternal and Child Health Care Hospital in July 2021 for global developmental delay was selected as the study subject. Clinical data of the child was reviewed. The child was subjected to whole exome sequencing, and relevant literature was reviewed. This study has been approved by the Medical Ethics Committee of Luoyang Maternal and Child Health Care Hospital (No. YCCZ-KS-KY-2021-03).Results:The patient, a 2-year-and-4-month-old girl, had presented with global developmental delay, gait instability, low limb muscle strength, and absence language development. Her parents were both healthy and denied relevant family history. Genetic testing revealed that she has harbored a de novo heterozygous c. 44A>G (p.H15R) missense variant of the EEF1A2 gene (NM_001958.5), which was unreported previously. Based on the guidelines from the American College of Medical Genetics and Genomics, the variant was rated as pathogenic. Conclusion:The c. 44A>G (p.H15R) variant of the EEF1A2 gene probably underlay the pathogenesis in this patient. Above finding has also enriched the mutational spectrum of the EEF1A2 gene.

Objective:To explore the risk factors of recent cardiovascular and cerebrovascular events and long-term all-cause mortality in hemodialysis (HD) patients.Methods:The clinical data of two groups of retrospective cohort study, which included newly admitted HD (group A) and maintenance HD (group B) patients respectively, were sourced from the HD Center of Beijing Anzhen Hospital, Capital Medical University. The endpoint events were defined as occurrence of cardiovascular or cerebrovascular events or all-cause mortality at less than 12 mouths of dialysis age in group A, and all-cause mortality in group B. The patients were divided into event group and non-event group based on whether endpoint events occurred during the follow-up period. The baseline and follow-up clinical data within the two groups were compared. Cox regression model was used to analyze the risk factors of endpoint events in HD patients.Results:A total of 104 HD patients were enrolled in group A, with 70 males (67.3%), aged (61.54±14.97) years old. The follow-up time was 12.0 (10.0,12.0) months, and 29 patients (27.9%) had endpoint events. In group A, the event group had a higher proportion of peripheral arterial disease ( χ2=6.067, P=0.014), and lower low-density lipoprotein-cholesterol ( t=-2.316, P=0.023) and body mass index ( t=-2.245, P=0.028) than those in the non-event group. A total of 116 HD patients were enrolled in group B, with 86 males (74.1%), aged (65.89±10.06) years old. The follow-up time was 37.5 (21.0, 59.0) months, and 40 patients (34.5%) had endpoint events. In group B, the event group had lower serum albumin ( t=-3.182, P=0.002) and potassium ( t=-2.532, P=0.013) than those in the non-event group. Multivariate Cox regression analysis showed that high hemoglobin compliance rate ( HR=0.977, 95% CI 0.957-0.998, P=0.031) and high serum albumin ( HR=0.836, 95% CI 0.776-0.901, P<0.001) were protective factors of all-cause mortality in maintenance HD patients. Conclusions:The presence of peripheral arterial disease, low low-density lipoprotein-cholesterol and low body mass index may increase the risk of recent cardiovascular and cerebrovascular events in newly HD patients. Substandard hemoglobin and serum albumin may increase the risk of long-term all-cause mortality in maintenance HD patients.
