Objective: To construct a hypertension risk prediction model for residents aged 18-79 years, so as to provide an assessment tool for early screening and prevention of hypertension in high-risk groups. Methods: The permanent residents aged 18-79 years from 6 townships (streets) in Fangshan District of Beijing Municipality were selected as the study subjects using a multi-stage stratified random sampling method from March to June 2023. Demographic information, lifestyle, body mass index (BMI), blood pressure, fasting blood glucose, and blood lipid were collected through questionnaire survey, physical examination, and laboratory tests. Subjects were randomly divided into training and validation sets at a 7∶3 ratio. The logistic regression model was used to screen the risk factors of hypertension, and a hypertension risk prediction nomogram was constructed. Receiver operating characteristic (ROC) curve, calibration curve, and decision curve analysis were used to verify the discrimination, fit, and clinical application value of the model. Results: A total of 4 438 subjects were included, including 2 365 males (53.29%) and 2 073 females (46.71%), with a mean age of (44.99±14.90) years. The prevalence of hypertension was 35.29% (1 566 cases), and the standardized prevalence was 24.74%. The logistic regression model screened out 9 influencing factors of hypertension. The nomogram was established as ln[p/ (1-p)]= -2.873 + 0.935×40-<50 years + 1.463×50-<60 years + 1.908×60-<70 years + 2.346×70-79 years + 0.298×male-0.675×college degree or above + 0.384×smoking + 0.227×drinking + 0.572×overweight + 1.449×obesity + 0.557×heart rate ≥80 beats/min + 0.428×diabetes + 0.484×dyslipidemia. The area under the ROC curve of the validation set was 0.821 (95%CI: 0.798-0.843), and the calibration curve results showed that the calibration curve fitted the actual curve well. Decision curve analysis showed that the threshold probability was in the range of 0.10 to 0.70, and the model had good predictive value and clinical application value. Conclusion The nomogram based on age, gender, educational level, smoking, drinking, body mass index, heart rate, diabetes, and dyslipidemia can be used to predict the risk of hypertension among residents aged 18-79 years.

ObjectiveTo explore the mechanism of Jiawei Wendantang in preventing and treating diabetic atherosclerosis by observing the effect of this prescription on the nuclear factor-κB / NOD-like receptor protein 3（NF-κB/NLRP3） pathway and related inflammatory cytokines in rat model of diabetic atherosclerosis. MethodFifty-four SPF-grade rats were randomized into blank， model， atorvastatin （0.9 mg·kg^-1·d^-1）， and high-， medium-， low-dose （18.2， 9.1， 4.55 g·kg^-1·d^-1， respectively） Jiawei Wendantang groups. The rats in other groups except the blank group were modeled for diabetic atherosclerosis by intraperitoneal injection of streptozotocin and feeding with a high-sugar high-fat diet， and those in the blank group were injected with an equal dose of citric acid buffer and fed with a regular diet. The drug administration lasted for 4 weeks， and the blood glucose level in the tail vein was measured every 6 days. After the last administration， the rats were anesthetized for sample collection. Enzyme-linked immunosorbent assay was employed to measure the serum levels of interleukin-18 （IL-18）， C-reactive protein （CRP）， tumor necrosis factor-α （TNF-α）， and intercellular adhesion molecule-1 （ICAM-1）. Western blot was employed to determine the relative protein levels of NF-κB p65， NLRP3， and ICAM-1 in the abdominal aorta. Real-time quantitative polymerase chain reaction was employed to determine the mRNA levels of NLRP3 and interleukin-1β （IL-1β） in the abdominal aorta. The pathological changes in the thoracic aorta were observed by hematoxylin-eosin staining. ResultCompared with the blank group， the model group showed elevated levels of IL-18， CRP， TNF-α， and ICAM-1 in the serum and blood glucose （P<0.05， P<0.01）， up-regulated protein levels of NF-κB p65， NLRP3， and ICAM-1 （P<0.01）， and up-regulated mRNA levels of NLRP3 and IL-1β （P<0.05）. Compared with model group， Jiawei Wendantang lowered the levels of IL-18， CRP， TNF-α， ICAM-1 and blood glucose （P<0.05， P<0.01）， down-regulated the protein levels of NF-κB p65， NLRP3， and ICAM-1 （P<0.01）， and down-regulated the mRNA levels of NLRP3 and IL-1β （P<0.05， P<0.01）. Moreover， Jiawei Wendantang alleviated the pathological injuries in the thoracic aorta. ConclusionJiawei Wendantang may modulate the NF-κB/NLRP3 signaling pathway to reduce the release and adhesion of inflammatory cytokines and regulate the blood glucose level to treat diabetic atherosclerosis.

Objective: To analyze the genetic characteristics of a five generations pedigree with homozygous familial hypercholesterolemia (HoFH). Methods: Prospective study. Twenty family members included a proband diagnosed as familial hyperlipidemia at the cardiology Department of Xi′an Children′s Hospital in October 2018 were research object. Clinical data were collected. Genome DNAs were extracted. Whole exons sequencing was performed on the proband using target capture next generation sequencing. Candidate gene mutation sites identified by bioinformatics were verified by Sanger sequencing in the family members. The genotype-phenotype correlation of the pedigree was analyzed between heterozygous mutation carriers and non-carriers. Results: The proband was a 7-years and 10-month-old boy. He was born with a roundgreen bean size yellow skin protuberance in the skin of the coccyx. Since the age of 3-4 years old, xanthoma-like lesions with a diameter of 0.5-1.5 cm gradually appeared in the skin of bilateral elbow joints, knee joints and Achilles tendon. The height, weight and intellectual development of the child were the same as those of normal children at the same age. No similar xanthoma-like lesion was found in the other family members. The proband′s total cholesterol (TC) reached 18.16-21.24 mmol/L, and his low density lipoproteincholesterol (LDL-C) was 14.08-15.51 mmol/L. Carotid ultrasonography showed diffuse sclerotic plaques in bilateral carotid and vertebral arteries, and color Doppler echocardiography revealed aortic valve thickening and calcification. Gene testing identified that the proband carried a homozygous mutation C. 418G>A (p. E140K) in LDLR gene inherited from his parents who had a consanguineous marriage and carried a heterozygous mutation of LDLR-E140K, respectively.The TC, LDL-C and apolipoproteinB (ApoB) of LDLR-E140K gene heterozygous carriers ((8.40±0.13), (6.79±0.01) and (1.95±0.05) mmol/L, respectively) were significantly higher than those of non-carriers ((4.59±0.28), (3.35±0.39) and (0.86±0.10) mmol/L, t=7.269, 4.595, 6.311, respectively, P<0.05). Conclusions LDLR-E140K gene homozygous mutation is first reported to be associated with most severe phenotype HoFH. The genotype-phenotype analysis of the pedigree shows that the clinical phenotype of the proband with homozygous mutation is the most serious, and all the heterozygous mutation carriers present with hypercholesterolemia phenotype. The investigation confirms that LDLR-E140K is the pathogenic variation of familial hyperlipidemia.

Objective: To observe the effect of 2 Hz electroacupuncture (EA) on long term depression (LTD) of synaptic transmission in the spinal dorsal horn in rats with neuropathic pain, so as to explore the central mechanisms of the antinociceptive effects of 2 Hz electroacupuncture on neuropathic pain. Methods: The neuropathic pain models were produced by tight ligation of the L5/L6 spinal nerves in Sprague Dawley rats. The C fiber evoked field potentials in the spinal dorsal horn were recorded with extracellular recording techniques. The parameters of the electroacupuncture were as follows: frequency of 2 Hz, wavelength of 0.6 ms, intensity of 1,2,3 mA lasting 10 min for each intensity, stimulation time of 30 min. The positive stimulating electrode was placed in acupoint “sanyinjiao” and the negative electrode in “zusanli”. Results: (1) 2 Hz electroacupuncture significantly decreased the amplitudes of C fiber evoked field potentials in the spinal dorsal horn in rats with neuropathic pain to (49.4?0.6)% of the control, compared with that (100.1?1.2) % of the control before EA (unpaired t test, P
