The European Society of Cardiology (ESC) released the "2024 ESC guidelines for the management of elevated blood pressure and hypertension" on August 30, 2024. This guideline updates the 2018 "Guidelines for the management of arterial hypertension." One notable update is the introduction of the concept of "elevated blood pressure" (120-139/70-89 mm Hg). Additionally, a new systolic blood pressure target range of 120-129 mm Hg has been proposed for most patients receiving antihypertensive treatment. The guideline also includes numerous additions or revisions in areas such as non-pharmacological interventions and device-based treatments for hypertension. This article interprets the guideline's recommendations on definition and classification of elevated blood pressure and hypertension, and cardiovascular disease risk assessment, diagnosing hypertension and investigating underlying causes, preventing and treating elevated blood pressure and hypertension. We provide a comparison interpretation with the 2018 "Guidelines for the management of arterial hypertension" and the "2017 ACC/AHA guideline on the prevention, detection, evaluation, and management of high blood pressure in adults."

Objective To study the transcriptional expression of Chlorophyti Laxi R.Br.using high-throughput sequencing technology.Methods Total RNA of Chlorophtum laxum R.Br.was extracted,followed by library construction,sequencing,and de novo assembly to obtain unigene sequences.These sequences were then annotated and compared to acquire genetic information of the Chlorophtum laxum R.Br.transcriptome.Results A total of 29 325 unigene were identified,with an average length of 1 026 bp and an N50 of 1 697 bp.Among them,20 338 unigene were functionally annotated in at least one database,with Chlorophtum laxum R.Br.showing the highest sequence similarity to Asparagus officinalis.In the Kyoto Encyclopedia of Genes and Genomes(KEGG)database,13 392 unigene were annotated,including genes involved in flavonoid biosynthesis and ubiquinone and other terpenoid-quinone biosynthesis pathways.Thirty-five upstream genes related to Chlorophtum laxum R.Br.saponin biosynthesis were identified.In the Gene Ontology(GO)database,16 728 unigene were annotated,covering cellular anatomical entities,binding,and biological processes.Using the Microsatellite Identification Tool(MISA),11 486 assembled unigene longer than 1 000 bp were analyzed for simple sequence repeats(SSRs),resulting in the identification of 5 178 SSR loci,for which primers were designed using Primer 3.0.By comparing Chlorophtum laxum R.Br.unigene with the transcription factor database,657 transcription factors,including bHLH,MYB,and WRKY,were identified.Conclusion The transcriptome data provide a foundation for studying the biosynthetic pathways and functional genes of medicinal active components in Chlorophtum laxum R.Br.,and also contribute to the conservation and development of its resources.

Objective:To evaluate the radiological and functional outcomes of moderate to severe hallux valgus patients with enlarged distal metatarsal articular angle (DMAA) underwent modified Chevron osteotomy.Methods:The clinical data of patients with moderate and severe hallux valgus with increased distal metatarsal joint angle who accepted surgery operation in the Department of Foot and Ankle Surgery of Yantaishan Hospital from October 2020 to December 2022 were retrospectively analyzed. All patients underwent modified Chevron osteotomy. Taking the proximal end of the metatarsal head centre as the osteotomy apex, the vertical arm osteotomy line in the sagittal plane made an angle of ≤80° with the metatarsal stem, the horizontal plane was inclined to the lateral distal end of the metatarsal head by about 10°, and the sagittal plane metatarsal arm osteotomy line made an angle of ≥90° with the vertical arm osteotomy line; at the proximal osteotomy surface, another cuneiform bone with its base on the medial and its apex on the lateral was resected. The deformity correction was insufficient and Akin osteotomy was performed in combination. Weil osteotomy was performed in combination with metatarsalgia. Radiological assessment including the hallux valgus angle (HVA), intermetatarsal angle (IMA), DMAA, the joint congruity angle (JCA), forefoot bone width and soft tissue width was performed preoperatively and at last follow-up postoperatively. American Orthopedic Foot and Ankle Society/hallux metatarsophalangeal-interphalangeal scale (AOFAS/HMIS) was used for clinical and functional evaluation, total score from 0 to 100, with higher scores indicating better function.Visual analogue scale (VAS) was used for pain valuation, total score from 0 to 10, with higher scores indicating more pain. A questionnaire survey on patient satisfaction was conducted at the last follow-up. Shapiro-Wilk test was used for normal distribution test, and measurement data following normal distribution were represented as Mean±SD. Paired t-test was used for comparison before and after operation. Other indicators conformed to non-normal distribution were denoted by M( Q1, Q3) and were tested by Wilcoxon signed-rank test. P<0.05 was considered statistically significant. Results:Fifty-two feet of 48 patients (5 males, 43 females; mean age (52.4±14.9) years; range, 24 to 78 years) were enrolled. Before the operation, 8 feet combined with metatarsalgia, among them, 7 feet underwent modified Chevron+ Akin+ Weil osteotomy, and 1 foot underwent modified Chevron+ Weil osteotomy. Among the 44 feet without metatarsalgia, 11 feet underwent modified Chevron osteotomy and 33 feet underwent modified Chevron+ Akin osteotomy. The mean follow-up time was 17.8 months (12-24 months). The HVA angle decreased from 38.30°±7.59° before surgery to 10.00°±5.73° at the last follow-up; the IMA angle decreased from 16.08°(12.89°, 18.24°) to 4.81°(3.62°, 7.57°); the DMAA angle decreased from 18.35°(13.03°, 27.47°) to 4.52°(2.68°, 7.09°); JCA decreased significantly from 15.93°(10.25°, 23.06°) to 3.56°(1.71°, 6.98°); forefoot bone width decreased from (90.05±6.12) mm to (82.75±5.01) mm; forefoot soft tissue width decrease from 102.25(96.77, 107.15) mm to 98.08(91.01, 100.60) mm; the VAS decreased from 6(5.5, 7) points to 0(0, 0) points; the score according to the AOFAS/HMIS forefoot was increased from 49(42, 52.5) points to 90(83.5, 95) points; which were statistically significant compared with that before the operation (all P<0.01). There was no statistically significant difference in the first metatarsal length before the operation and at the last follow-up [54.60(52.86, 56.42) mm vs. 54.29(51.85, 56.35) mm, P>0.05]. In the post-operative period, there were 8 feet had limited metatarsophalangeal joint movement, 3 feet had limited interphalangeal joint movement, 5 feet had limited movement in both joints, which did not affect walking and function; 3 feet of partial recurrence of hallux valgus, 2 feet of screw irritation pain, 1 foot of cystic degeneration of the first metatarsal head, and no complications such as metastatic metatarsalgia. The satisfaction survey showed that the satisfaction rate of patients with the orthopedic effect was 90.4% (47/52). Conclusion:The modified Chevron osteotomy is effective in the treatment of moderate to severe hallux valgus with enlarged DMAA. Careful intraoperative operation and standardized postoperative rehabilitation training can reduce complications.

Objective: To understand the epidemiological characteristics of physical assault injuries among students in Dalian, so as to provide evidence for the prevention and control of physical assault injuries among students. Methods: Data of student physical assault injuries came from the Dalian Hospital Injury Monitoring System from 2018 to 2022, descriptive epidemiological methods and Chi square tests were used for statistical analysis. Results: A total of 1 413 cases of physical assault injuries among students were reported, and the sex ratio between male and female was 4.12∶1. The number of reported physical assault injuries dropped from 414 cases in 2018 to 209 cases in 2022. The group of senior middle school/secondary vocational school had the highest proportion of cases (40.13%). Injuries occurred in all months, with the highest number of reported cases in June, October, and November, accounting for 33.97%. The main causes of injuries were blunt instrument injuries and falls, accounting for 70.06% and 23.35% respectively. The proportion of male (71.24%) was significantly higher than female (65.22%) in blunt instrument injuries ( χ 2=3.84, P <0.05). Nearly 75.58% of injuries occurred during leisure time. The main locations of injuries took place in schools and roads, accounting for 51.52% and 23.35% respectively. Contusions and sharp instrument injuries were one of the most common types of injuries, accounting for 67.16% and 22.29% respectively. The main area of injury was concentrated in the head, accounting for 59.52%. Most of injuries were mild and moderate, accounting for 72.26% and 27.60 %, respectively. Conclusions Schools are the main location for physical assault injuries among students, with boys and middle school students being the most vulnerable populations. Targeted intervention measures should be implemented to effectively reduce the occurrence of physical assault injuries among students.

BACKGROUND:Bone defects are caused by many factors,such as inflammation,tumor,trauma or bone diseases.Erythropoietin can promote the differentiation of mesenchymal stem cells into osteoblasts and osteoclasts and act on vascular endothelial cells to induce angiogenesis and accelerate the repair of bone and cartilage defects.Erythropoietin is a growth factor with potential application in bone tissue engineering construction. OBJECTIVE:To expound the application and potential mechanism of erythropoietin in bone tissue engineering. METHODS:The first author searched the related articles published in CNKI,WanFang,VIP,and PubMed databases from 2004 to 2022 by computer.Search terms were"erythropoietin,bone defect,bone regeneration,angiogenesis,osteogenesis,osteoblast,osteoclast,bone tissue engineering"in Chinese and English.Finally,64 articles were included for review. RESULTS AND CONCLUSION:(1)Erythropoietin can directly act on osteoblasts and osteoclasts in the bone marrow microenvironment by promoting the differentiation of mesenchymal stem cells into osteoblasts,osteoclasts,adipocytes,nerve cells and stromal cells.The activation of Wnt/β-catenin,hypoxia-inducible factor 1α/vascular endothelial growth factor,p38 MAPK and EphrinB2/EphB4 signaling pathways mediates the osteogenic differentiation of mesenchymal stem cells.(2)Erythropoietin can not only regulate the production of erythrocytes to alter the oxygen-carrying capacity of blood but also stimulate vascular endothelial cells to promote angiogenesis.The new blood vessels can carry oxygen,nutrients,growth factors,and bone progenitor cells necessary for osteogenesis to the osteogenic site,thereby promoting bone formation and fracture healing.(3)Currently,erythropoietin is being used as a growth factor with osteogenic and angiogenic effects in various types of scaffold materials such as chitosan,polycaprolactone,bioceramics,and nanofibers through various drug delivery methods.Erythropoietin,along with other growth factors such as bone morphogenetic protein-2 and bone morphogenetic protein-9,has been applied to the surface of scaffold materials to participate in the repair of bone defects.Erythropoietin has demonstrated excellent practicality in the construction of new tissue-engineered bone and has potential clinical application value.

Objective:To evaluate the clinical effectiveness and safety of combined face and neck injections of botulinum toxin type A to improve face and neck aging.Methods:From January 2020 to January 2023, 30 female patients with age of 29-66 years, average (42.2±8.8) years, underwent face and neck combined injection of A-type botulinum toxin in the Department of Dermatology, Henan Provincial People′s Hospital. The injection sites included the forehead, between the eyebrows, around the eyes, the dorsum of the nose, and the mandibular margin, etc. The efficacy was assessed by the wrinkle severity scale (FWS) and the AB value of the distance from the lowest point of the mandibular margin on the midline of the hemiface to the level of the medial canthus at 4 and 24 weeks after the injection, as well as the subjective degree of improvement by the Global Aesthetic Improvement of the Face Scale (GAIS) and the Self-perception of Age (SPA), and the satisfaction of the patients and post-injection adverse reactions.Results:At 4 weeks after the injection, the total effective rate of improvement of wrinkles in all parts of the upper face was 100% (30/30), and there was a statistically significant difference in the improvement of AB ( t=28.35, P<0.05). At 24 weeks after the injection, the total effective rate of improvement of wrinkles in all parts of the upper face ranged from 16.7% (5/30) to 36.7% (11/30), and the improvement of AB still showed a statistically significant difference ( t=3.98, P<0.05). 100% (30/30) and 66.7% (20/30) of patients assessed their facial status as improved on GAIS at 4 and 24 weeks after the injection, respectively, and 100% (30/30) and 63.3% (19/30) of patients perceived themselves as younger. Patient satisfaction was 100% (30/30). After injection, there were 5 cases of slight ecchymosis at the injection site and 1 case of weakness in eyebrow elevation in the 30 patients, which disappeared on their own within 1 to 2 weeks. Conclusions:The therapeutic effect of face and neck combined injection of botulinum toxin type A on facial rejuvenation is obvious, with high patient′s satisfaction and no serious adverse reactions.

The intestinal flora and gut barrier function are of great significance for gut function and human health. When the intestinal flora is disrupted and the gut barrier structure is disrupted, it can lead to bacterial translocation, endotoxin influx into the bloodstream, and the production of pro-inflammatory factors, leading to various tissue damage in the body. Tongfu method in TCM can affect the intestinal environment by regulating intestinal permeability and immune response, restoring normal intestinal movement, and regulating the structure and metabolites of intestinal flora, thereby maintaining intestinal homeostasis and body health. The research on regulating intestinal flora and improving intestinal barrier function by Tongfu method can provide reference for further research on the relationship between TCM and intestinal microecology, and provide ideas for clinical treatment.

Objective:To summarize the best evidence of intracranial hypertension nursing for adult patients with severe brain injury, and to provide reference for clinical nursing practice.Methods:According to the evidence-based methodology, a systematic search of Chinese and English literature on intracranial hypertension nursing of adult patients with severe brain injury was conducted in domestic and foreign databases such as CNKI, Wanfang, PubMed, Cochrane Library and Cinahl Plus and so on, as well as related guide websites and professional association websites from the establishment of database to August 2022.

In total, 33 pieces of best evidence were obtained from 8 dimensions, including intracranial pressure related threshold, assessment and monitoring, respiratory care, circulation care, analgesic and sedative care, temperature care, nutrition care and cerebrospinal fluid care.Conclusions:This study summarizes the evidence-based basis of intracranial hypertension nursing in adult patients with severe brain injury, which provides a basis for the standardized construction of clinical nursing strategies and empirical research.

Objective: To investigate the effect of Kamistad gel on oral ulcer healing and the expression of tumor necrosis factor α (TNF-α), interleukin 6 (IL-6) and epidermal growth factor (EGF) after oral administration in ulcer tissue of rats and to provide animal experimental data for the clinical application of Kamistad gel. Methods: The oral ulcer rat model was established by chemical cauterization. The rats were randomly divided into four groups: Kamistad group (Kamistad gel), befuxin group (befuxin gel), lidocaine group (lidocaine cream), blank control group (normal saline), with 12 rats in each group. The ulcer area of the rats in each group was measured before and 1, 3 and 5 days after treatment; at 1 day after treatment, the duration of swabbing behavior within 3 minutes of intraoral capsaicin infusion was recorded to evaluate the degree of pain; the ulcer tissue was collected at 5 days after treatment, and the histopathological changes were observed by HE staining, the expression of TNF-α, IL-6 and EGF in the ulcer tissue was detected by immunohistochemistry and ELISA. Results: At 1 day after treatment, the duration of mouth wiping induced by capsaicin was significantly shorter in the Kamistad group than in the blank control and befuxin groups (P < 0.05), but there was no significant difference between the Kamistad and lidocaine groups (P >0.05). At 5 days after treatment, the ulcer area was significantly smaller in the Kamistad group than in the blank control and lidocaine groups (P < 0.05), and there was no significant difference between the Kamistad and befuxin groups (P >0.05). At 5 days after treatment, H&E staining of the oral ulcer tissue sections showed significantly reduced levels of inflammatory cells and significantly proliferated fibroblasts and better epithelial hyperplasia in the Kamistad group compared with those in the lidocaine and blank control groups, and there were no differences between the Kamistad and befuxin groups. At 5 days after treatment, the expression levels of TNF-α, IL-6 and EGF in the ulcer tissue of rats in each group were significantly different (P < 0.05). Compared with the blank control and lidocaine groups, the expression of TNF-α and IL-6 was significantly decreased and the expression of EGF was significantly increased in the Kamistad group (P < 0.05); there were no significant differences in the expression of the above three factors between the Kamistad and befuxin groups (P > 0.05). Conclusion Kamistad gel exhibited anti-inflammatory, analgesic and healing effects on experimental oral ulcers.
