Objective To explore the effect of sevelamer carbonate on blood phosphorus,vascular calcification,and parathyroid function in maintenance hemodialysis(MHD)patients.Methods MHD patients were selected as the research subjects and divided into treatment group and control group according to the treatment plan using a cohort method.The control group was given calcium carbonate chewable tablets orally at a dose of 1.25 g,bid,while the treatment group was given sevelamer carbonate tablets orally at a dose of 0.8 g,tid;the duration of treatment for both groups was 6 months.The clinical efficacy,blood phosphorus,blood calcium,coronary artery calcification score,parathyroid function[intact parathyroid hormone(iPTH),parathyroid volume],and levels of inflammatory factors[C-reactive protein(CRP),interleukin-6(IL-6),tumor necrosis factor-α(TNF-α)]were compared between the two groups,and the occurrence of adverse drug reactions was recorded.Results The total effective rates of the treatment group and the control group were 92.45％(49 cases/53 cases)and 77.55％(38 cases/49 cases)respectively,showing statistically significant difference(P＜0.05).After 6 months of treatment,the blood phosphorus levels of the treatment group and the control group were(1.63±0.31)and(2.07±0.36)mmol·L-1,respectively;blood calcium levels were(2.31±0.17)and(2.47±0.12)mmol·L-1,respectively;coronary artery calcification scores were 71.81±15.45 and 86.03±17.49,respectively;iPTH expression levels were(223.59±64.85)and(304.25±74.61)pg·mL-1,respectively;parathyroid volumes were(1.03±0.26)and(1.17±0.21)cm3,respectively;CRP expression levels were(5.12±1.35)and(6.59±1.66)mg·L-1,respectively;IL-6 expression levels were(16.32±2.81)and(19.84±3.62)ng·L-1,respectively;TNF-αexpression levels were(18.54±3.88)and(22.69±4.89)ng·L-1,respectively.The differences in the above indicators between the treatment group and the control group were all statistically significant(all P＜0.05).The total incidence of adverse drug reactions in the treatment group and the control group were 9.43％(5 cases/53 cases)and 6.12％(3 cases/49 cases),respectively,with no statistically significant difference(P＞0.05).Conclusion Sevelamer carbonate can reduce blood phosphorus levels in MHD patients,has minimal effect on blood calcium concentration,improves parathyroid function in patients,delays vascular calcification,and has good clinical application effects.

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 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.

Objective With the widespread of transcatheter aortic valve replacement(TAVR)in patients with severe symptomatic aortic stenosis(AS),the life-cycle management has become a major determinant of prognosis.Methods A total of 408 AS patients who underwent successfully TAVR from June 2021 to August 2023 were consecutively enrolled in Hospital Valve Intervention Center.Patients were assigned to the Usual Care(UC)group between June 2021 and October 2022,while patients were assigned to the Heart Multi-parameter Monitoring(HMM)group between November 2022 and August 2023.The primary endpoint was defined as composite endpoint within 6 months post-TAVR,including all-cause death,cardiovascular death,stroke/transient ischemic attack,conduction block,myocardial infarction,heart failure rehospitalization,and major bleeding events.Secondary endpoints were the time interval(in hours)from event occurrence to medical consultation or advice and patient satisfaction.Statistical analysis was performed using Kaplan-Meier and multivariable Cox proportional hazards models.Results The incidence of primary endpoint in HMM group was significantly lower than that in UC group(8.9％vs.17.7％,P=0.016),the driving event was the rate of diagnosis and recognition of conduction block.The average time intervals from event occurrence to receiving medical advice were 3.02 h in HHM group vs.97.09 h in UC group(P＜0.001).Using cardiac monitoring devices and smart healthcare platforms provided significant improving in patients long-term management(HR 0.439,95％CI 0.244-0.790,P=0.006).Conclusions The utilization of cardiac monitoring devices and smart healthcare platforms effectively alerted clinical events and improved postoperative quality of life during long-term management post TAVR.

Objective To establish an acute exposure model of extreme plateau hypobaric hypoxia environment and explore transcriptomic changes related to learning and memory impairment in rats.Methods Healthy male SD rats aged 6-weeks,200-250 g,were selected and divided into control group and plateau group.The control group was treated with normal pressure and oxygen(19 rats),and the plateau group was placed in a hypobaric hypoxia chamber(19 rats)at a simulated altitude of 8000 meters and treated for 72 hours.Behavioral changes were detected with 16 animals from each group using contextual fear conditioning and Morris water maze(8 rats each).Three hippocampal tissues were extracted from each group for transcriptomic sequencing,and the molecular mechanism of learning and memory impairment induced by extreme plateau environment was analyzed by Gene Ontology(GO),Kyoto Encyclopedia of Genes and Genomes(KEGG)and gene set enrichment analysis(GSEA)enrichment.Results The behavioral result showed that compared with the control group,the fear memory and spatial learning memory abilities of rats in plateau group were decreased.GO and KEGG analyses showed that the extreme altitude environment reshaped the hippocampal microenvironment and affected the intercellular signal transmission,while GSEA analysis showed that the extreme altitude environment up-regulated the gene set related to the plasma membrane and extracellular matrix.Conclusion The extreme plateau environment at an altitude of 8000 meters could affect the microenvironment of rat hippocampus,destroy intercellular connections and impair intercellular communication and then induce learning and memory impairment.

Background/Aims: Finite nucleos(t)ide analog (NA) therapy has been proposed as an alternative treatment strategy for chronic hepatitis B (CHB), but biomarkers for post-treatment monitoring are limited. We investigated whether measuring hepatitis B core-related antigen (HBcrAg) after NA cessation may stratify the risk of subsequent clinical relapse (CR). Methods: This retrospective multicenter analysis enrolled adults with CHB who were prospectively monitored after discontinuing entecavir or tenofovir with negative HBeAg and undetectable HBV DNA at the end of treatment (EOT). Patients with cirrhosis or malignancy were excluded. CR was defined as serum alanine aminotransferase > two times the upper limit of normal with recurrent viremia. We applied time-dependent Cox proportional hazard models to clarify the association between HBcrAg levels and subsequent CR. Results: The cohort included 203 patients (median age, 49.8 years; 76.8% male; 60.6% entecavir) who had been treated for a median of 36.9 months (interquartile range [IQR], 36.5–40.1). During a median post-treatment follow-up of 31.7 months (IQR, 16.7–67.1), CR occurred in 104 patients with a 5-year cumulative incidence of 54.8% (95% confidence interval [CI], 47.1–62.4%). Time-varying HBcrAg level was a significant risk factor for subsequent CR (adjusted hazard ratio [aHR], 1.53 per log U/mL; 95% CI, 1.12–2.08) with adjustment for EOT HBsAg, EOT anti-HBe, EOT HBcrAg and time-varying HBsAg. During follow-up, HBcrAg <1,000 U/mL predicted a lower risk of CR (aHR, 0.41; 95% CI, 0.21–0.81). Conclusions Dynamic measurement of HBcrAg after NA cessation is predictive of subsequent CR and may be useful to guide post-treatment monitoring.

Network pharmacology, molecular docking, and in vivo and in vitro experiments were employed to study the molecular mechanism of Blaps rynchopetera Fairmaire in the treatment of non-small cell lung cancer(NSCLC). The components of B. rynchopetera were collected by literature review, and the active components were screened out through the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP). PharmMapper was used to obtain the targets of the active components. The targets of NSCLC were obtained from DrugBank, GeneCards, OMIM, TTD, and PharmGKB. The Venn diagram was drawn to identify the common targets shared by the active components of B. rynchopetera and NSCLC. The "drug component-target" network and protein-protein interaction(PPI) network were constructed by Cytoscape, and the key targets were screened by Centiscape. Gene Ontology(GO) annotation and Kyoto Encyclopedia of Genes and Genomes(KEGG) enrichment of the above key targets were performed by DAVID. AutoDock and PyMOL were used for the molecular docking between the key targets and corresponding active components. A total of 31 active components, 72 potential targets, and 11 key targets of B. rynchopetera against NSCLC were obtained. The active components of B. rynchopetera had good binding activity with key targets. Further, the serum containing B. rynchopetera was prepared and used to culture human lung adenocarcinoma A549 cells. The CCK-8 assay was employed to determine the inhibition rates on the growth of A549 cells in blank control group and those exposed to different concentrations of B. rynchopetera-containing serum, cisplatin, and drug combination(B. rynchopetera-containing serum+cisplatin) for different time periods. The cell migration and invasion of A549 cells were detected by cell scratch assay and Transwell assay, respectively. Western blot was employed to determine the expression levels of B-cell lymphoma-2(Bcl-2), Bcl-2-associated X(Bax), caspase-3, cell division cycle 42(CDC42), proto-oncogene tyrosine-protein kinase SRC, and vascular endothelial growth factor(VEGF) in A549 cells. C57BL/6 mice were inoculated with Lewis cells and randomly assigned into a model control group, a B. rynchopetera group, a cisplatin group, and a drug combination(B. rynchopetera+cisplatin) group, with 12 mice per group. The body weight and the long diameter(a) and short diameter(b) of the tumor were monitored every other day during treatment, and the tumor volume(mm~3) was calculated as 0.52ab~2. After 14 days of continuous medication, the mice were sacrificed for the collection of tumor, spleen, and thymus, and the tumor inhibition rate and immune organ indexes were calculated. The tissue morphology of tumors was observed by hematoxylin-eosin(HE) staining, and the positive expression of Bax, Bcl-2, caspase-3, CDC42, SRC, and VEGF in the tumor tissue was detected by immunohistochemistry. The results indicated that B. rynchopetera and the drug combination regulated the expression levels of Bax, Bcl-2, caspase-3, CDC42, SRC, and VEGF to inhibit the proliferation, migration, and invasion of A549 cells and Lewis cells, thus playing a role in the treatment of NSCLC via multiple ways.

Objective: To explore the value of catheter-based adrenal ablation in treating Cushing's syndrome (CS)-associated hypertension. Methods: A clinical study was conducted in patients with CS, who received catheter-based adrenal ablation between March 2018 and July 2023 in Daping Hospital. Parameters monitored were blood pressure (outpatient and 24-hour ambulatory), body weight, clinical characteristics, serum cortisol and adrenocorticotropic hormone (ACTH) at 8 am, 24-hour urinary free cortisol (24 h UFC), fasting blood glucose and postoperative complications. Procedure effectiveness was defined as blood pressure returning to normal levels (systolic blood pressure<140 mmHg (1 mmHg=0.133 kPa) and diastolic blood pressure<90 mmHg), cortisol and 24 h UFC returning to normal and improvement of clinical characteristics. The parameters were monitored during follow up in the outpatient department at 1, 3, 6, and 12 months after catheter-based adrenal ablation. Results: A total of 12 patients (aged (40.0±13.2) years) were reviewed. There were 5 males, with 5 cases of adenoma and 7 with hyperplasia from imaging studies. Catheter-based adrenal ablation was successful in all without interruption or surgical conversion. No postoperative complication including bleeding, puncture site infection, adrenal artery rupture or adrenal bleeding was observed. The mean follow up was 28 months. Compared to baseline values, body weight declined to (59.48±11.65) kg from (64.81±10.75) kg (P=0.008), fasting blood glucose declined to (4.54±0.83) mmol from (5.53±0.99) mmol (P=0.044), outpatient systolic blood pressure declined to (128±21) mmHg from (140±19) mmHg (P=0.005), diastolic blood pressure declined to (78±10) mmHg from (86±11) mmHg (P=0.041), and the mean ambulatory daytime diastolic blood pressure declined to (79±12) mmHg from (89±8) mmHg (P=0.034). Catheter-based adrenal ablation in 8 patients was defined as effective with their 24 h UFC significantly reduced after the procedure (1 338.41±448.06) mmol/L from (633.66±315.94) mmol/L, P=0.011). The change of 24 h UFC between the effective treatment group and ineffective group was statistically significant (P=0.020). The postoperative systolic blood pressure in the treated adenoma group was significantly lower than those of hyperplasia group (112±13) mmHg vs. (139±20) mmHg, P=0.026). Conclusions: For patients with CS-associated hypertension who are unwilling or unable to undergo surgical treatment, catheter-based adrenal ablation could improve the blood pressure and cortisol level. Catheter-based adrenal ablation could be a safe, effective, and minimally invasive therapy. However, our results still need to be validated in further large-scale studies.
