OBJECTIVE To evaluate the efficacy， safety and cost-effectiveness of vonoprazan （VPZ） in the treatment of gastroesophageal reflux disease （GERD） by rapid health technology assessment， and provide evidence for clinical decision-making. METHODS English and Chinese databases including PubMed， Medline， Cochrane Library， CNKI， VIP， and Wanfang data as well as the official websites of domestic and international health technology assessment agencies were searched by computer from the database establishment to August 2024. After literature screening， data extraction and quality evaluation of included studies were conducted by two researchers， the results were described and analyzed qualitatively. RESULTS A total of 21 pieces of literature were included， involving 15 systematic reviews/meta-analyses and 6 pharmacoeconomic studies. In terms of efficacy， compared with the control regimen （different doses of VPZ， placebo， other positive controls or combination therapy）， VPZ （mainly 20 mg/d VPZ） significantly improved the total response rate， mucosal healing rate at 2nd week， symptom remission rate， and maintenance rate at 12th and 24th week after mucosal healing （P＜0.05）； when the endoscopic Los Angeles classification was C/D， the effective rate of VPZ was significantly higher than that of the control regimen （P＜0.05）. In terms of safety， there was no significant difference in the incidence of adverse events between VPZ and the control regimen for GERD treatment （P＞0.05）， but the risk of elevated serum gastrin and abnormal liver function caused by long-term use of VPZ was higher than that of the control regimen （P＜0.05）. In terms of cost-effectiveness， compared with rabeprazole， lansoprazole and esomeprazole， VPZ had a cost- effectiveness/cost-utility advantage. CONCLUSIONS VPZ is effective， safe and cost-effective in the treatment of GERD.

Preeclampsia (PE) is a severe gestational disorder characterized by hypertension and proteinuria, with a subset of cases exhibiting an immune-driven phenotype marked by placental overexpression of proinflammatory cytokines and chronic inflammatory damage, profoundly impacting fetal development. To elucidate the pathophysiology of this PE subtype, we established an inflammation-driven PE mouse model via lipopolysaccharide (LPS) intraperitoneal injection, systematically evaluating histopathological changes in maternal heart, liver, lung, kidney, and placenta, and integrating transcriptomic profiling to uncover molecular mechanisms. LPS administration robustly induced maternal hypertension and proteinuria, hallmarks of PE, without significantly altering organ or fetal weights. Histological analyses revealed pronounced inflammatory damage in the maternal lung, kidney, and placenta, with the lung exhibiting the most severe pathology, characterized by inflammatory cell infiltration, alveolar wall thickening, and interstitial edema-challenging the conventional focus on placental and renal primacy in PE. Placental labyrinth and junctional zones displayed extensive structural disruption and necrosis, indicating functional impairment. Transcriptomic analysis identified 27 inflammation-related genes consistently upregulated across tissues, with protein-protein interaction networks pinpointing Il1β, Il6, Ccl5, Ccl2, Cxcl10, Tlr2, and Icam1 as hub genes. Quantitative PCR validation confirmed Tlr2 as a central regulator, evidenced by significant upregulation of Tlr2 in lung, kidney, and placenta of LPS-induced PE mice, while Cxcl10 exhibited placenta-specific upregulation, suggesting a synergistic inflammatory axis in placental pathology. These findings highlight the lung as a critical, yet underappreciated, target in inflammation-driven PE, reframe the multi-organ inflammatory landscape of the disease, and nominate Tlr2 and Cxcl10 as potential diagnostic biomarkers and therapeutic targets, offering new avenues for precision intervention in PE.

OpenSim is an open source, free motion simulation and gait analysis software, which can be used to dynamically simulate and analyze the complex motion of the human body, and is widely used in human biomechanical research. Since OpenSim can analyze multi-dimensional motion data such as muscle strength, joint torque, and muscle synergistic activation during human movement, it can be used to study the biomechanical mechanism of musculoskeletal imbalance diseases and various treatment methods in TCM orthopedics, and has a broad application prospect in the field of TCM orthopedics. By the analysis of the basic characteristics, elements, analysis process, and application prospects of OpenSim, it is concluded that OpenSim musculoskeletal model has a large application space in the field of traditional Chinese medicine orthopedic, which is helpful to explain the pathogenesis and mechanism of diseases, and promote the precision diagnosis and treatment of orthopedics diseases;the application of OpenSim musculoskeletal model can solve the problem that the previous research paid attention to the bone malalignment and not enough attention to the tendon, and provide a new method for the research of orthopedic diseases. At present, there are still problems in the promotion and application of OpenSim, such as large equipment requirements and high operation threshold. Therefore, multidisciplinary cooperation, clinical research, and data sharing are the basic research strategies in this field.

OBJECTIVES: To evaluate the effectiveness of single-balloon and double-balloon enteroscopy in diagnosing pediatric small bowel diseases and assess the diagnostic efficacy of computed tomography enterography (CTE) for small bowel diseases using enteroscopy as the reference standard. METHODS: Clinical data from 576 children who underwent enteroscopy at Hunan Children's Hospital between January 2017 and December 2023 were retrospectively collected. The children were categorized based on enteroscopy type into the single-balloon enteroscopy (SBE) group (n=457) and double-balloon enteroscopy (DBE) group (n=119), and the clinical data were compared between the two groups. The sensitivity and specificity of CTE for diagnosing small bowel diseases were evaluated using enteroscopy results as the standard. RESULTS: Among the 576 children, small bowel lesions were detected by enteroscopy in 274 children (47.6%).There was no significant difference in lesion detection rates or complication rates between the SBE and DBE groups (P>0.05), but the DBE group had deeper insertion, longer procedure time, and higher complete small bowel examination rate (P<0.05). The complication rate during enteroscopy was 4.3% (25/576), with 18 cases (3.1%) of mild complications and 7 cases (1.2%) of severe complications, which improved with symptomatic treatment, surgical, or endoscopic intervention. Among the 412 children who underwent CTE, the sensitivity and specificity for diagnosing small bowel diseases were 44.4% and 71.3%, respectively. CONCLUSIONS SBE and DBE have similar diagnostic efficacy for pediatric small bowel diseases, but DBE is preferred for suspected deep small bowel lesions and comprehensive small bowel examination. Enteroscopy in children demonstrates relatively good overall safety. CTE demonstrates relatively low sensitivity but comparatively high specificity for diagnosing small bowel diseases.

Objective:To analyze the correlation between elastic modulus of shear wave elastography of periurethral prostatic tissue and serum prostate-specific antigen(PSA)in patients with benign prostatic hyperplasia(BPH).Methods:A total of 200 BPH patients who received treatment in the Second People's Hospital of Hefei from October 2019 to October 2022 were collected by convenient sampling method,and all patients were subjected to ultrasound shear wave elastography and serum PSA examination,and the elastic modulus of periurethral prostate tissue was measured by shear wave elastography,and the mean of them was obtained.They were divided into mild group(96 cases),moderate group(59 cases)and severe group(45 cases)according to the results of the International Prostate Symptom Score(IPSS).At the same time,the related information of 30 cases without prostatic lesions who were selected from the prostate examination population were included into healthy control groups.The correlation between the elastic modulus of periurethral prostatic tissue and serum PSA was analyzed and compared.Results:Statistical analysis showed that there was significant difference in the elastic modulus value of prostate among various groups(F=190.914,P<0.05).Compared with the healthy control group,the elastic modulus values of prostate of the mild,moderate and severe groups were significantly increased,and the differences were significant(t=6.572,14.172,18.441,P<0.05),respectively.Compared with the mild group,the elastic modulus values of prostate of the moderate and severe groups were significantly increased(t=7.853,18.274,P<0.05),respectively.Compared with the moderate group,the elasticity modulus value of prostate of the severe group significantly increased(t=11.371,P<0.05).There was significant difference in serum PSA among BPH patients with different degrees(F=126.143,P<0.05).Compared with the healthy control group,the serum PSA values of the mild,moderate and severe groups significantly increased(t=10.694,14.368,13.804,P<0.001),respectively.Compared with the mild group,the serum PSA values of the moderate and severe group significantly increased(t=6.401,13.047,P<0.05),respectively.Compared with the moderate group,the serum PSA value of the patients in the severe group significantly increased(t=7.293,P<0.001).There was no significant correlation between serum PSA and the elastic modulus of periurethral tissues in the healthy control group(P>0.05).There were significant positive correlation between serum PSA and the elastic modulus of periurethral tissues in the mild,moderate and severe groups(r=0.314,0.296,0.354,P<0.05),respectively.Conclusion:Both serum PSA level and elastic modulus value of periurethral prostate tissue of BPH patients significantly increase,and there is a positive correlation between them.

The transmission cycle of echinococcosis was established in 1853.More than 160 years have elapsed since Iceland initiated control measures to break the transmission cycle of echinococcosis in 1863.Control plans have been implemented in more than a dozen countries/territories,and lessons have been learned from failures as well as successes.In this review,we fo-cus on the failure experiences,which have also promoted successes in the control of cystic echinococcosis(caused by the para-site Echinococcus granulosus)in regions including Iceland,New Zealand,Uruguay,Wales(England),Turkana(Kenya),and Sardinia(Italy).The causes of the failures were analyzed,and the effects of health education,dog deworming,and con-trol measures for infected animal slaughter on echinococcosis control are comprehensively summarized.However,no suc-cessful experience has been reported in the control of alveolar echinococcosis(caused by the parasite Echinococcus multilocu-laris).On the basis of the biological characteristics of E.mul-tilocularis parasitization in dogs for a duration of 30 days and larvae parasitization in rodents,the fundamental measure for controlling alveolar echinococcosis is administration of monthly deworming treatments to dogs in high prevalence areas.

Objective To explore dose-effect relationship of biomechanical parameters in treating atlantoaxial joint disor-der by slimming manipulation.Methods From October 2022 to May 2023,18 patients with atlantoaxial joint disorders were treated,including 10 males and 8 females;aged from 24 to 27 years old with an average of(25.50±l.10)years old;CT of cer-vical vertebra showed 16 patients with right side distortion and 2 patients with left side distortion.The mechanical parameters of treatment of atlantoaxial joint disorder by tendon relaxation manipulation were measured by wearing massage manipulation gloves.The magnitude,frequency and mechanical curve of force during tendon relaxation and starting force,pulling force,pulling time and mechanical curve during rehabilitation were quantified,the differences between the affected and contralateral manipulations were compared.Results The maximum force and frequency of Fengchi(GB20)on the affected side were(19.82±2.02)N and(116.83±14.49)times/min,and opposite side were(13.87±2.19)N and(188.89±16.03)times/min,re-spectively.There were statistically difference in the maximum force and frequency of both sides(P＜0.05).The maximum force and frequency of Quepen(ST12)on the affected side were(14.44±3.27)N and(139.06±28.47)times/min,and those on the opposite side were(9.41±1.38)N and(142.50±28.47)times/min.There was difference in maximum force on both sides(P＜0.05).The starting force,turning force and turning time of the affected side were(14.16±5.98)N,(11.56±6.63)N,(0.14±0.03)S,and the contralateral side were(8.94±3.39)N,(8.30±4.64)N,(0.18±0.04)S,respectively.The difference of starting force,turning force and turning time on both sides were statistically significant(P＜0.05).Conclusion By applying a light re-laxation force on the affected side,the mechanical balance between cervical vertebrae could be restored,and recovery trend of atlantoaxial joint disorder could be strengthened.On this basis,the atlantoaxial odontoid process could be reversed by applying a light rotation force,which reflects the characteristics of high safety of the manipulation.

Objective To construct curcumin pyrazole derivative by the reaction of diketone of curcumin and benzylhydrazine based on the above structure-activity relationship,and to explore its antioxidant activity to provide experimental basis for the development of curcumin antioxidant derivative.Methods Curcumin-N-substituted pyrazole derivative was synthesized from curcumin and benzylhydrazine.The structures of the derivative were confirmed by infrared spectroscopy(IR),nuclear magnetic resonance spectroscopy(1H-NMR,13C-NMR)and LC-MS.The antioxidant activity in vitro of the derivative was evaluated by determination of curcumin and its pyrazole derivative scavenging ability for 2,2-diphenyl-1-picrylhydrazyl(DPPH)free radical and 2,2'-azino-bis-3-ethylbenzothiazoline-6-sulfonic acid(ABTS)free radical.Results Curcumin pyrazole derivative was successfully synthesized.Curcumin and its pyrazole derivative showed good free radical scavenging effects in the range of 4.6-73.6,6.25-100 μg·mL-1,respectively,with a significant dose-effect relationship.The half-maximal inhibition(IC50)values of curcumin and its pyrazole derivatives determined by DPPH method were 14.24,40.37 μg·mL-1,respectively,while the IC50 values of curcumin and its pyrazole derivatives determined by ABTS method were 36.65,19.26 μg·mL-1,respectively.Conclusion The antioxidant activity of β-dione of curcumin was retained through the substitution of the pyrazole ring,and the curcumin pyrazole derivative deserves further investigation as a potential antioxidant.

OBJECTIVE To evaluate the efficacy， safety and cost-effectiveness of vericiguat in the treatment of heart failure （HF） by rapid health technology evaluation method， and provide reference for the selection and decision-making of clinical treatment plans. METHODS Chinese and foreign databases such as CNKI， PubMed and related health technology evaluation websites were searched by computer. Relevant researchers independently screened literature， extracted data， and comprehensively analyzed the results of the included literature based on literature quality evaluation. RESULTS A total of 17 pieces of literature were included， involving 12 systematic reviews/meta-analyses and 5 pharmacoeconomic studies. The effectiveness analysis showed： for HF patients， compared with placebo， vericiguat （10 mg/d） significantly improved the EuroQol five dimensions questionnaire （EQ-5D） index and decreased the rate of hospitalization due to HF （P＜0.05）. For heart failure with reduced ejection fraction （HFrEF） patients， vericiguat reduced the incidence of hospitalization due to HF compared with sodium-glucose cotransporter 2 inhibitor （SGLT2i）（P＜0.05）； compared with angiotensin-converting enzyme inhibitor， vericiguat significantly reduced the occurrence risk of composite endpoints of cardiovascular death or hospitalization due to HF（P＜0.05）. For HFrEF patients with chronic kidney disease， vericiguat had a tendency to reduce the occurrence risk of composite endpoints of cardiovascular death or hospitalization due to HF compared with neurohormone inhibitors. Safety analysis showed： vericiguat did not increase drug-related adverse reactions compared to placebo （P＞0.05）. Economic analysis showed： domestic studies indicated that vericiguat had a higher incremental cost-effectiveness ratio. CONCLUSIONS Vericiguat has good safety and efficacy in the treatment of HF but does not possess an economic advantage in the Chinese population.
