Objective We aim to analyse semaglutide related adverse events in real-world,overall and by gender and age subgroups and compare the differences of different gender and age patients in adverse events,in order to supply references for security usage in the clinic.Methods OpenVigil 2.1 was used to search FDA Adverse Event Reporting System for semaglutide related adverse events from the establishment of the databases to April 2023.According to age and gender,patients were divided into 18-64 years old group and≥65 years old group,male group and female group.We selected ten adverse events which we interested(nausea,diarrhoea,vomiting,pancreatitis,cholecystitis,cholelithiasis,hypoglycaemia,diabetic retinopathy,acute kidney injury and thyroid cancer/medullary thyroid cancer)and analyzed overall and each group of semaglutide adverse events.Results A total of 5 330 cases and 15 558 adverse events were collected.2 935 patients aged 18-64 old group years with 8 553 adverse events;2 395 patients aged≥65 years old group with 7 005 adverse events.2 231 male group patients with 6 195 adverse events;3 059 female group patients with 9 277 adverse events.The sex of 40 patients was unknown.Nausea(1 089 cases/7.00％),vomiting(775 cases/4.98％)and diarrhoea(545 cases/3.50％)remained the most common adverse events.The constituent ratio of pancreatitis was significantly higher in patients aged 18-64 years old group than in patients aged 65 years old group(P＜0.05);the constituent ratio of diarrhoeaand cholelithiasis was significantly lower in patients aged 18-64 years old group than patients aged≥65 years old group(P＜0.05).The constituent ratio of diarrhoea,vomiting,pancreatitis,cholecystitis,cholelithiasis,diabetic retinopathy,and acute kidney injurywas significantly higher in male group patients than in female group(P＜0.05).Conclusion Nausea,diarrhoea and vomiting remined the most common adverse events of semaglutide.Male should be more concerned about gastrointestinal,pancreatitis,gallbladder events,retinopathy and acute kidney injury.Elderly patients should be more alert diarrhoea and cholelithiasis.

Hypertension and osteoporosis(OP)are common diseases in middle-aged and elderly people,and the number of patients with both diseases has gradually increased in recent years.Because the onset of the disease is hidden,it is easy to cause fractures and serious complications of heart,brain and kidney in the later stage,which not only seriously damages the quality of life of patients,but also increases the difficulty of clinical treatment.Therefore,it is particularly necessary to strengthen the research on this disease.More and more studies have found that the disorder of intestinal flora will lead to the occurrence of OP,while the intestinal flora of patients with hypertension is obviously out of balance.Therefore,this paper thinks that intestinal flora may be the key influencing factor of hypertension complicated with OP,and the imbalance of intestinal flora will lead to the imbalance of short-chain fatty acid metabolism,immune inflammatory reaction and increased sympathetic nerve activity,thus causing the imbalance of bone homeostasis and promoting the occurrence of OP.Therefore,it is suggested that regulating intestinal flora may be a new way to intervene hypertension complicated with OP.

Objective To observe the effects of Zhengan Xifeng decoction on bile acid spectrum of bile and sterol 12α hydroxylase(CYP8B1)in spontaneously hypertensive rats(SHR).Methods Fifty SHR were randomly divided into model group,control group(1.0 mg·kg-1·d-1 benazepril by gavage)and experimental-L,-M,-H groups(8.63,17.25 and 34.50 g·kg-1·d-1 Zhengan Xifeng decoction by gavage),another 10 homologous male Wistar-Kyoto(WKY)rats were taken as the normal group.The model group and the normal group were given the same amount of distilled water.The rats in the 6 groups were administered once a day for 8 weeks.The animal non-invasive sphygmomanometer was used to measure the blood pressure of rats in each group by tail-cuff method;the bile acid spectrum of rats in each group was detected by UPLC-MS/MS;the expression of CYP8B1 mRNA in rat liver tissue was detected by real-time fluorescence quantitative polymerase chain reaction.Results The systolic blood pressure at the 8th week of the experimental-M,-H groups,control group,model group,normal group were(169.63±12.10),(170.32±9.64),(175.95±15.47),(189.47±7.42)and(146.40±9.45)mmHg;the diastolic blood pressure at the 8th week were(135.10±11.99),(129.73±15.10),(135.18±17.62),(149.20±8.83)and(110.53±10.92)mmHg;the relative expression levels of CYP8B1 mRNA were 3.36±0.94,5.45±1.46,4.29±0.95,0.89±0.14 and 1.00±0.00,respectively.Compared with the model group,the above indexes in the experimental-M,-H groups were statistically significant(P＜0.01,P＜0.05).Compared with the model group,the bile acid spectrum of experimental-L,-M,-H groups bile changed significantly,and a total of 9 different bile acids were found,which were hyodeoxycholic acid,glycohyodeoxycholic acid,glycochenodeoxycholic acid,glycoursodeoxycholic acid,α-muricholic acid,ursodeoxycholic acid,cholic acid,β-muricholic acid and glycocholic acid.Conclusion Zhengan Xifeng decoction may correct bile acid spectrum disorder of bile and reduce blood pressure by up-regulating liver CYP8B1 expression.

Objective:To investigate the mechanisms underlying the effect of levocarnitine on myocardial cell fibrosis, proliferation, apoptosis and migration.Methods:Between June and December 2022, an overexpression vector for tissue inhibitor-1 of metalloproteinase(TIMP-1)and siRNA TIMP-1 were used to transfect rat H9c2 cardiomyocytes(from the cell bank of the Chinese Academy of Sciences), and transfection efficiency was measured using fluorescence reverse transcription quantitative PCR(RT-qPCR). After treating H9c2 cells with angiotensin Ⅱ(AngⅡ), the expression of the MMP3 and TIMP-1 genes in the cells was detected by RT-qPCR.A CCK8 kit was used to assess the effect of levocarnitine intervention on the proliferation of myofibroblasts after overexpression or knockdown of TIMP-1.The effects of levocarnitine on apoptosis and migration of myofibroblasts were detected by flow cytometry and Transwell assays.Results:The RT-qPCR results showed that the expression level of the MMP3 gene(1.38±0.05)in cardiomyocytes treated with AngⅡ for 24 hours exhibited an upward trend( P<0.01), while the expression level of the TIMP-1 gene(0.71±0.03)showed a downward trend( P<0.01). In addition, H9c2 cells with TIMP-1 overexpression(905.98±24.17)and knockdown(0.18±0.01)%, respectively, were successfully constructed.Based on CCK-8 detection results, knockdown of TIMP-1(86.56±7.98)% was able to promote the proliferation of H9c2 cells induced by levocarnitine( P<0.01). Apoptosis experiments showed that inhibition of TIMP-1 expression(23.22±2.69)significantly reduced the apoptosis level of H9c2 cells induced by levocarnitine( P<0.01). Migration experiments showed that inhibition of TIMP-1 expression(217.67±23.44)significantly promoted the migration ability of H9c2 cells induced by levocarnitine( P<0.01). Conclusions:After intervention to reduce TIMP-1 expression, levocarnitine can promote proliferation, inhibit apoptosis and promote migration of myofibroblasts and may therefore ameliorate myocardial fibrosis.

Osteoporotic proximal humeral fracture (OPHF) is one of the common osteoporotic fractures in the aged, with an incidence only lower than vertebral compression fracture, hip fracture, and distal radius fracture. OPHF, secondary to osteoporosis and characterized by poor bone quality, comminuted fracture pattern, slow healing, and severely impaired shoulder joint function, poses a big challenge to the current clinical diagnosis and treatment. In the field of diagnosis, treatment, and rehabilitation of OPHF, traditional Chinese and Western medicine have accumulated rich experience and evidence from evidence-based medicine and achieved favorable outcomes. However, there is still a lack of guidance from a relevant consensus as to how to integrate the advantages of the two medical systems and achieve the integrated diagnosis and treatment. To promote the diagnosis and treatment of OPHF with integrated traditional Chinese and Western medicine, relevant experts from Orthopedic Expert Committee of Geriatric Branch of Chinese Association of Gerontology and Geriatrics, Youth Osteoporosis Group of Orthopedic Branch of Chinese Medical Association, Osteoporosis Group of Orthopedic Surgeon Branch of Chinese Medical Doctor Association, and Osteoporosis Committee of Shanghai Association of Integrated Traditional Chinese and Western Medicine have been organized to formulate Expert consensus on the diagnosis and treatment of osteoporotic proximal humeral fracture with integrated traditional Chinese and Western medicine ( version 2024) by searching related literatures and based on the evidences from evidence-based medicine. This consensus consists of 13 recommendations about the diagnosis, treatment and rehabilitation of OPHF with integrated traditional Chinese medicine and Western medicine, aimed at standardizing, systematizing, and personalizing the diagnosis and treatment of OPHF with integrated traditional Chinse and Western medicine to improve the patients ′ function.

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.

In this study, three-dimensional ordered porous carbon materials were prepared using Acanthopanax senticosus herbal residues as raw material and KOH as activating agent through a one-step pyrolysis method. The prepared carbon-based material was systematically characterized by powder X-ray diffraction, scanning electron microscopy, N₂ adsorption-desorption and Fourier-transform infrared spectroscopy. The results show that the three-dimensional ordered porous carbon materials prepared with KOH as the activator via pyrolysis possess abundant functional groups, high porosity, and high specific surface area, with a specific surface area of 1 471.6 m²·g^-1. The three-dimensional ordered porous carbon materials prepared at 800 ℃ exhibits a high drug loading capacity (78.0%) and drug release rate (86.8%) for 5-fluorouracil. Three-dimensional orderly porous carbon materials show significant application advantages in drug construction, and their high specific surface area and adjustable pore size structure significantly improve the drug load rate and drug release rate, providing a solid foundation for the development of efficient and accurate drug delivery system.

Sirtuins(SIRTs),a group of NAD+dependent deacetylases,have attracted considerable attention in the field of neuro-degenerative diseases,especially Parkinson's disease(PD).They have critical impacts on cell survival and death through modulation of various biological processes,such as intracellular metabolism,stress response and DNA repair.In the pathogenesis of PD,Sirtuins play a crucial role and associated with pathophysiological processes such as mitochondrial function,oxidative stress,and neuronal apoptosis.Activa-tion of Sirtuins alleviates dyskinesia and neuronal damage in animal models of PD and also regulates the aggre-gation and clearance of α-synuclein,a pathological feature of the disease.Therefore,the modulation of Sirtuins is a potential strategy for treating PD.

Objective To investigate the effects and mechanism of β2 adrenergic receptors(ADRB2)in ferroptosis and autophagy induced by erastin(Era)in prostate cancer.Methods PC-3 cells were infected with lentivirus or control and set to sh-NC group(normal culture),sh-NC+Era group(10 μmol/L Era treatment for 24 h),sh-ADRB2 group(normal culture),and sh-ADRB2+Era group(10 μmol/L Era treatment for 24 h).The viability of the cells treated with Era and ferrostatin-1(Fer-1)was measured by CCK-8 assay.The cell morphology was analyzed by transmission electron microscopy.The malondialdehyde(MDA)content was measured by the Lipid Oxidation Detection Kit and the iron level by Iron Colorimetric Assay.Western blotting was used to detect the expressions of cystine-glutamate exchanger(XCT),ferritin heavy chain 1(FTH1),glutathione peroxidase 4(GPX4),p62,LC3,JNK,c-Jun,and p-c-Jun.PC-3 cells with ADRB2 knockdown were injected into nude mice to construct a xenograft model and then treated with Era.The animals were divided into sh-NC group,sh-NC+Era group,sh-ADRB2 group,and sh-ADRB2+Era group,with 4 mice in each group.The tumor volumes were recorded every other day and the final tumor weight was measured at study termination.The expressions of ADRB2,JNK,c-Jun,and p-c-Jun were detected by immunohistochemistry(IHC).Results The viability of PC-3 cells decreased after Era treatment(P<0.01)and recovered after Fer-1 treatment(P<0.01).Morphological changes of ferroptosis and autophagy were observed in Era-treated cells,and MDA and iron ion contents up-regulated(P<0.05 or P<0.01).Knockdown of ADRB2 and Era treatment further inhibited PC-3 cell viability(P<0.05),and MDA and iron ion contents up-regulated(P<0.01).The expressions of ferroptosis-related proteins FTH1,XCT,GPX4,and LC3 down-regulated(P<0.05 or P<0.05),p62 and JNK pathway-related proteins JNK,c-Jun,and p-c-Jun were up-regulated(P<0.01).After JNK inhibitor treatment,the expressions of FTH1,XCT,and LC3 increased,and p62 decreased(P<0.01).In the PC-3 xenograft model,tumor volume in sh-ADRB2+Era group was significantly smaller than those in sh-NC+Era group and sh-ADBR2 group(P<0.05 or P<0.01).IHC showed that compared with sh-NC group,ADRB2 protein expression level was down-regulated in sh-ADRB2 group(P<0.05),while JNK,c-Jun,and p-c-Jun protein expression levels were elevated(P<0.01).Compared with sh-NC+Era group,the ADRB2 protein expression level in sh-ADRB2+Era group was down-regulated,while JNK,c-Jun,and p-c-Jun protein expression levels were up-regulated(P<0.05).Conclusion ADRB2 regulated ferroptosis and autophagy induced by Era via JNK/c-Jun pathway in prostate cancer.

Objective To investigate the incidence rate,clinical characteristics,and prognosis of neonatal stroke in Shenzhen,China.Methods Led by Shenzhen Children's Hospital,the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022.The incidence,clinical characteristics,treatment,and prognosis of neonatal stroke in Shenzhen were analyzed.Results The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137,1/6 060,and 1/7 704,respectively.Ischemic stroke accounted for 75％(27/36);boys accounted for 64％(23/36).Among the 36 neonates,31(86％)had disease onset within 3 days after birth,and 19(53％)had convulsion as the initial presentation.Cerebral MRI showed that 22 neonates(61％)had left cerebral infarction and 13(36％)had basal ganglia infarction.Magnetic resonance angiography was performed for 12 neonates,among whom 9(75％)had involvement of the middle cerebral artery.Electroencephalography was performed for 29 neonates,with sharp waves in 21 neonates(72％)and seizures in 10 neonates(34％).Symptomatic/supportive treatment varied across different hospitals.Neonatal Behavioral Neurological Assessment was performed for 12 neonates(33％,12/36),with a mean score of(32±4)points.The prognosis of 27 neonates was followed up to around 12 months of age,with 44％(12/27)of the neonates having a good prognosis.Conclusions Ischemic stroke is the main type of neonatal stroke,often with convulsions as the initial presentation,involvement of the middle cerebral artery,sharp waves on electroencephalography,and a relatively low neurodevelopment score.Symptomatic/supportive treatment is the main treatment method,and some neonates tend to have a poor prognosis.
