To summarize the clinical experience of Professor WANG Jie in treating palpitation using the method of tonifying the kidneys and invigorating blood. It is believed that kidney yang deficiency and heart vessel stasis are the key pathogenesis of palpitation， and it is advocated to treat palpitation by tonifying the kidney and invigorating the blood. Meanwhile，the methods of draining water， dissolving phlegm， and fortifying the spleen to supplement the blood should be applied. For palpitation with kidney yang deficiency and heart vessel stasis with upward water， the treatment could use self-prescribed Bushen Huoxue Lishui Formula （补肾活血利水方）； for palpitation with phlegm obstruction in blood vessel， the treatment could use self-prescribed Bushen Huoxue Huatan Formula （补肾活血化痰方）； for palpitation with spleen yang deficiency， the treatment could use self-prescribed Bushen Huoxue Jianpi Formula （补肾活血健脾方）.

ObjectiveIn nature, objects cast shadows due to illumination, forming the basis for stereoscopic perception. Birds need to adapt to changes in lighting (meaning they can recognize stereoscopic shapes even when shadows look different) to accurately perceive different three-dimensional forms. However, how neurons in the key visual brain area in birds handle these lighting changes remains largely unreported. In this study, pigeons (Columba livia) were used as subjects to investigate how neurons in pigeon’s ventrolateral mesopallium (MVL) represent stereoscopic shapes consistently, regardless of changes in lighting. MethodsVisual cognitive training combined with neuronal recording was employed. Pigeons were first trained to discriminate different stereoscopic shapes (concave/convex). We then tested whether and how light luminance angle and surface appearance of the stereoscopic shapes affect their recognition accuracy, and further verify whether the results rely on specify luminance color. Simultaneously, neuronal firing activity of neurons was recorded with multiple electrode array implanted from the MVL during the presentation of difference shapes. The response was finally analyzed how selectively they responded to different stereoscopic shapes and whether their selectivity was affected by the changes of luminance condition (like lighting angle) or surface look. Support vector machine (SVM) models were trained on neuronal population responses recorded under one condition (light luminance angle of 45°) and used to decode responses under other conditions (light luminance angle of 135°, 225°, 315°) to verify the invariance of responses to different luminance conditions. ResultsBehavioral results from 6 pigeons consistently showed that the pigeons could reliably identify the core 3D shape (over 80% accuracy), and this ability wasn’t affected by changes in light angle or surface appearance. Statistical analysis of 88 recorded neurons from 6 pigeons revealed that 83% (73/88) showed strong selectivity for specific 3D shapes (selectivity index>0.3), and responses to convex shapes were consistently stronger than to concave shapes. These shape-selective responses remained stable across changes in light angle and surface appearance. Neural patterns were consistent under both blue and orange lighting. The decoding accuracy achieves above 70%, suggesting stable responses under different conditions (e.g., different lighting angles or surface appearance). ConclusionNeurons in the pigeon MVL maintain a consistent neural encoding pattern for different stereoscopic shapes, unaffected by illumination or surface appearance. This ensures stable object recognition by pigeons in changing visual environments. Our findings provide new physiological evidence for understanding how birds achieve stable perception (“invariant neural representations”) while coping with variations in the visual field.

ObjectiveTo understand the death status of major chronic diseases among the registered residents in Xuhui District， Shanghai from 2007 to 2021， and to analyze the probability and trend of premature death， so as to provide an evidence for the policy-making of disease control and prevention. MethodsBased on the data from the death registration system of the registered residents in Xuhui District， Shanghai from 2007 to 2021， the mortality rate of major chronic diseases， life expectancy without cause of death， potential years of life lost （PYLL）， average years of life lost （AYLL）， and premature death rate were calculated. Joinpoint 4.8 software was used to calculate the annual percentage change （APC） of premature death rate and its trend. ResultsIn 2021， the mortality rate and standardized mortality rate of four major chronic diseases， namely cardiovascular and cerebrovascular diseases， malignant tumors， diabetes mellitus and chronic lower respiratory diseases among the registered residents in Xuhui District， Shanghai was 767.75/100 000 and 234.69/100 000， respectively， accounting for 85.63% of the total causes of death among the residents in Xuhui District， Shanghai. The PYLL， AYLL and PYLL rate were 10 710.00 person-years， 1.49 years per person， and 11.43‰， respectively. Life expectancy increased by 14.91 years after removing the four major chronic diseases. From 2007 to 2021， the premature death rate of chronic diseases among the registered residents in Xuhui District decreased from 9.38% to 7.91% （APC=-1.09%，P<0.05）. Malignant tumors had the highest rate in premature death， and the premature death rate was higher in males than that in females， with a slower rate of decline than in females. Cardiovascular and cerebrovascular diseases， malignant tumors and chronic lower respiratory diseases showed a significant decreasing trend in premature death rate （APC=-1.30%， -1.20%， -5.42%， P<0.05）， while diabetes mellitus showed a significant increasing trend in premature death rate （APC=3.20%， P<0.05）. There was a significant increasing trend in the rate of premature death from diabetes mellitus in males （APC=5.15%， P<0.05） and a decreasing trend in the rate of premature death from diabetes mellitus in females （APC=-0.76%， P<0.05）. ConclusionCardiovascular and cerebrovascular diseases， malignant tumors， diabetes mellitus and chronic lower respiratory diseases are the main causes of death among the registered residents in Xuhui District. The probability of premature death of the residents in Xuhui District from major chronic diseases is at a low level， indicating that the prevention and control of chronic diseases in Xuhui District has achieved some success， but it is still difficult to realize the goals of the Outline of the "Healthy China 2030" Plan. Therefore， it is necessary to comprehensively carry out the control of risk factors such as tobacco use， harmful alcohol consumption， salt intake， hypertension， hyperglycemia and obesity， especially to strengthen the control of risk factors for male residents， as well as early diagnosis and treatment of malignant tumors， cardiovascular and cerebral vascular diseases and diabetes mellitus， and to implement the disease management mechanism to reduce premature death.

ObjectiveTo observe the effect of Xiaoke drink on insulin resistance in ob/ob mice and explore the mechanism. MethodEighteen ob/ob mice were randomly assigned into model， Xiaoke drink （17.68 g·kg^-1）， and atorvastatin （0.01 g·kg^-1） groups （n=6）， and six C57BL/6 mice were selected as the normal group. Mice in the normal and model groups were administrated with the same amount of distilled water. Fasting body weight， weekly food intake， and weekly water intake were measured at a fixed time. Fasting plasma glucose （FPG） and 2-hour post-load plasma glucose （2 hPG） were measured before and after 8-week intervention. After intervention， total cholesterol （TC）， triglyceride （TG）， fasting insulin （FINS）， Homeostasis Model Assessment-Insulin Resistance （HOMA-IR）， blood routine， and alkaline phosphatase （ALP） were measured. Western blot was employed to determine the expression levels of ubiquitin-specific protease 20 （USP20） and 3-hydroxy-3-methylglutaryl coenzyme A reductase （HMGCR） in the liver. The pancreas was stained with hematoxylin-eosin for observation. ResultCompared with the model group， the Xiaoke drink group showed decreased body weight of ob/ob mice （P<0.05， P<0.01）， declined growth trend of body weight （P<0.05， P<0.01）， reduced weekly average water intake， lowered levels of FPG， 2 hPG， TC， and HOMA-IR （P<0.05， P<0.01）， and down-regulated expression level of USP20 in the liver （P<0.05）. HMGCR content was positively correlated with USP20 expression. In addition， Xiaoke drink promoted the recovery of islet tissue morphology and function in ob/ob mice. ConclusionXiaoke drink can ameliorate insulin resistance in ob/ob mice by inhibiting USP20/HMGCR expression， reversing cholesterol biosynthesis process， and reducing cholesterol level.

Objective To describe the distribution characteristics of knee and ankle joint range of motion and muscle atrophy related indexes in patients with Kashin-Beck disease(KBD)in Shaanxi Province so as to explore the correlation of knee and ankle joint range of motion(ROM)with muscle atrophy indexes and provide reference for clinical characteristics analysis of KBD patients.Methods To investigate the registered KBD patients from KBD areas in Shaanxi Province,we measured the general demographic data of the patients were collected and the ROM of the knee joint(flexion and extension),the ankle joint(dorsiflexion and plantar flexion),and the muscle atrophy related indexes such as the upper arm circumference,thigh circumference,calf circumference and grip strength.According to the population characteristics,i.e.,gender,age,body mass index(BMI)and KBD grade,the median and quartile of joint ROM and muscle atrophy of KBD patients were reported,and then the differences in each index among different groups were analyzed.Partial correlation analysis was used to explore the correlation between indicators after controlling for variables such as gender,age and BMI.Results A total of 480 patients with KBD were investigated in this study,who consisted of 249(51.9％)males and 231(48.1％)females,with an average age of(63.10±7.32)years and an average BMI of(23.49±8.90)kg/m2.The knee flexion ROM,knee extension ROM,ankle dorsiflexion ROM and ankle plantar flexion ROM were[105.0(95.0,120.0)]°,[0.0(-15.0,0.0)]°,[5.0(0.0,15.0)]° and[20.0(15.0,30.0)]°,respectively,in KBD patients in Shaanxi Province.The left thigh circumference,right thigh circumference,left calf circumference,right calf circumference,and upper arm circumference were[43.0(40.0,47.0)]cm,[43.0(39.0,47.0)]cm,[29.0(27.0,32.0)]cm,[29.5(27.0,32.0)]cm,[27.0(25.0,30.0)]cm,respectively.The left hand grip strength and right hand grip strength were[13.4(9.5,18.4)]kg and[13.9(9.8,18.2)]kg,respectively.With the increase of age,the extension range of the left and right knee joints of KBD patients showed a decreasing trend(H=31.499,31.847;all P＜0.001).The range of motion of bilateral knee flexion was higher in the normal BMI group than in the overweight or obese group,with statistically significant differences(H=7.753,12.333;P=0.021,0.002).The knee flexion,thigh circumference,and calf circumference of the left and right sides showed a decreasing trend under different KBD grades(H=14.345,17.256,8.000,8.462,8.558,9.633;all P＜0.05).Correlation analysis showed that knee flexion ROM was positively correlated with thigh circumference,calf circumference,and grip strength in patients with KBD(all P＜0.05).There was a positive correlation between knee extension ROM and thigh circumference in patients with KBD(P＜0.01).Conclusion The impaired joint ROM and muscle atrophy are serious in KBD patients in Shaanxi Province,and there is a correlation between joint motion and muscle atrophy.

Objective This study aimed to estimate the therapeutic effects of preformed metal crown(PMC)and pre-fabricated zirconia crowns(ZC)on decayed primary morals in children,as well as to analyze the possible influencing fac-tors.Methods A retrospective cohort study was performed on the data of 192 patients(aged 3 to 8)in the Stomatologi-cal Department of Shenzhen Children's Hospital from October 2021 to December 2021.The decayed mandibular first molars were selected and restored by vital-pulp therapy followed by PMC and ZC,including 96 cases(96 caries)in the PMC group and 96 cases(96 caries)in the ZC group.Oral clinical examination was performed at 3 months,1 year,and 2 years after treatment,overwiewing the clinical therapeu-tic effects and periodontal status of PMC and ZC groups,as well as recording the crown integrity,gingival index(GI),probing bleeding index(BI),plaque index(PLI)and various prosthetic indices.Results No significance differences existed in the periodontal status of PMC and ZC groups at 3 months,1 year,and 2 years after treatment(P>0.05).However,the GI,BI,and PLI in the PMC group were higher than those in the ZC group at 3 months,1 year,and 2 years after treatment,and the difference was dramatically signifi-cant(P<0.05).No significances difference existed in various prosthetic indices(P>0.05),as well as in the GI,BI,and PLI,between the two groups(P>0.05).No significant differences existed in various prosthetic indices between genders after PMC restoration(P>0.05).The scores of girls in various prosthetic indices after ZC restoration were higher than those of boys(P<0.05).Pearson correlation analysis indicated an inverse correlation between age in the PMC group and the GI,BI,PLI,and FDI indices(P<0.01),rather than in the ZC group(P>0.05).Conclusion PMC and ZC can be ap-plied to restore deciduous molar caries.The periodontal status of deciduous teeth in ZC group was superior to that in the PMC group.The periodontal status of deciduous teeth in PMC group may be stable with increased age.

Objective To explore the clinical characteristics of pediatric patients with cerebral palsy(CP)who also have comorbid epilepsy.Methods A retrospective analysis was conducted on the clinical data of 155 pediatric patients with CP and comorbid epilepsy admitted to the Third Affiliated Hospital of Zhengzhou University from January 2019 to December 2022.Patients were divided into 4 groups based on CP subtype:spastic diplegia group(n=29),spastic hemiplegia group(n=33),spastic quadriplegia group(n=73),and non-spastic group(n=20).Differences in sex,season of birth,birth weight,gestational age,and the relationship between gestational age and weight were compared among the groups.Additionally,the relationships between perinatal risk factors,MRI classification system(MRICS),gross motor function classification system(GMFCS),and the age of the first onset of epilepsy with respect to CP subtype were analyzed.Results Among the 155 patients,101 were male and 54 were female.A lower proportion of patients with spastic hemiplegia was observed with a gestational age of 28-31+6 weeks compared with those with spastic diplegia and spastic quadriplegia(P=0.009).The proportion of patients with a history of asphyxia in spastic hemiplegia group was significantly lower than that in the other 3 groups,and the proportion of patients with hypoxic-ischemic encephalopathy(HIE)in spastic hemiplegia group was significantly lower than in that both spastic quadriplegia group and non-spastic group(P<0.05).The proportion of patients in spastic quadriplegia group who had their first seizure at an age of<1 year was significantly higher than that in spastic diplegic group(P=0.041).The spastic diplegia group exhibited a higher percentage of white matter damage compared with the other 3 groups,and had a lower percentage of gray matter damage compared with both spastic hemiplegic group and non-spastic group(P=0.001).The proportion of patients with GMFCS levels Ⅳ-Ⅴ in spastic quadriplegia group was higher than those in the other 3 groups(P<0.001),and the proportion of patients with levels Ⅰ-Ⅲ in spastic hemiplegia group was significantly higher than those in spastic quadriplegia group and non-spastic group(P<0.001).Conclusion Significant differences were observed among pediatric patients with different subtypes of CP and comorbid epilepsy in factors such as gestational age,history of asphyxia,HIE history,age of first seizure,MRICS classification and GMFCS levels.

Objective To analyze the imaging features of pulmonary artery sarcoma(PAS)on CT and MRI.Methods The clini-cal features,CT and MRI findings of 21 patients with pathologically confirmed PAS were analyzed retrospectively.Results All PAS lesions involved the central pulmonary artery,of which 15 cases involved the main pulmonary artery and bilateral pulmonary artery trunks,4 cases involved the main pulmonary artery and right pulmonary artery trunk,1 case involved the main pulmonary artery and left pulmonary artery trunk,and 1 case involved the right pulmonary artery trunk.Five cases involved the pulmonary artery valve and right ventricular outflow tract as well.Nineteen cases of PAS showed complete filling defects in the central pulmonary artery,and the other 2 cases presented with nodular or lobulated filling defects attached to the pulmonary artery wall.The proximal margin of 19 PAS lesions was bulging or lobulated,and the distal pulmonary artery of 9 PAS lesions showed aneurysm-like dilatation.On MRI,all 13 cases of PAS were hyperintense on fat-suppressed T2WI,of which 11 cases were hyperintense on diffusion weighted imaging(DWI),and all lesions demonstrated significantly heterogeneous enhancement or delayed enhancement.Conclusion On computed tomography pul-monary angiography(CTPA),filling defects which grow expansively in the central pulmonary artery,and which have proximal bul-ging shape or distal aneurysm-like dilatation are highly suggestive of PAS.On contrast-enhanced MRI,the significantly heterogene-ous enhancement mass in the central pulmonary artery should be highly suspected of PAS.
