Objective:To analyze suicide methods and demographic characteristics of attempted suicide pa-tients in Baise City,Guangxi and to provide the basis for suicide intervention.Methods:A retrospective analysis method was conducted on the case data of attempted suicide patients treated in the emergency departments of 14 general hospitals in Baise City from 2018 to 2021.The situation of attempted suicide patients was recorded using the suicide patient information collection forms.Results:Among the 2 529 attempted suicide patients,1 636 committed-suicide by taking pesticides,557 used therapeutic drugs,112 used rodenticides,and 53 used carbonmonoxide(CO).The proportion of male and farmer suicides by taking pesticides was higher,and the proportion of female and non-farmer suicides by taking therapeutic drugs was higher.Multivariate analysis showed that the proportion of patients aged 45-60 years old patients who took pesticide was higher(OR=3.18),while the proportion of patients aged 45～60 who took therapeutic drugs was lower(OR=0.19).The proportion of suicides taking pesticides and using carbon monoxide significantly decreased in 2020(OR=0.56)and 2021(OR=0.52),while the proportion of sui-cides taking therapeutic drugs significantly increased in 2020(OR=2.04)and 2021(OR=3.18).Conclusion:Proportion of attempted suicide by taking pesticides is the most common method of suicide among residents in Baise City,with males,farmers,and middle-aged groups being the most affected.The proportion of attempted suicide by taking medication has significantly increased,with a higher incidence among women.

Objective To analyze the application value of 3D Slicer software in endoscopic transsphenoidal surgery for pituitary adenoma resection.Methods A retrospective analysis was made on the clinical data of 36 patients with pituitary adenomas treated with 3D Slicer-assisted endoscopic transsphenoidal surgery(3D Slicer group)in the Department of Neurosurgery,The Second Affiliated Hospital of Xi'an Jiaotong University,from January 2024 to December 2024.Preoperatively,multimodal images were fused and reconstructed using 3D Slicer software to systematically evaluate bony anatomical structures such as sphenoid sinus ostia,intrasphenoidal septa,and sellar floor structures,design the size of pedicled nasoseptal flaps,and clarify the positional relationships between pituitary adenomas and surrounding vital structures including the internal carotid artery,pituitary gland,and optic chiasm,so as to provide real-time guidance for intraoperative procedures.Meanwhile,45 patients with pituitary adenomas treated with neuronavigation-assisted endoscopic transsphenoidal surgery from January 2023 to December 2023 were included as the control group(neuronavigation group).The surgical outcomes and postoperative complications were compared between the two groups.Results Compared with the neuronavigation group,the 3D Slicer group demonstrated higher identification rates of the optic nerve groove and carotid artery impression(94.4％vs.77.8％),shorter operative time[(2.9±0.6)h vs.(3.5±0.9)h],less intraoperative bleeding[(159.7±70.5)mL vs.(237.8±96.0)mL],and a lower incidence of postoperative olfactory dysfunction(8.3％vs.26.7％),with statistically significant differences(P＜0.05).However,there were no statistically significant differences between the two groups in the identification rate of the sphenoid sinus ostium(100.0％vs.97.8％),gross total resection rate(75.0％vs.64.4％),and the incidence of other postoperative complications,including cerebrospinal fluid leakage(0.0％vs.6.7％),intracranial infection(2.8％vs.11.1％),transient diabetes insipidus(30.6％vs.22.2％),and hypopituitarism(38.9％vs.37.8％,P＞0.05).Conclusion 3D Slicer software helps improve the mastery of anatomical basics in endoscopic transsphenoidal approach among junior and primary physicians,enhancing the clinical efficacy and safety of pituitary adenoma resection,and thus is worthy of clinical promotion.

Objective:To assess the effects of recognition function of four-lead electrocardiogram(ECG)synchronization technique and multi-parameter fusion technique in reducing the number of false alarms and improving the quality of alarms in intensive care units(ICU).Methods:Four-lead ECG synchronization technique and multi-parameter fusion technique were used to strengthen the monitoring and assessment for the alarm of clinical monitors,and reduce the false alarm rate of monitors.The clinical alarm data of bed units corresponding to 48 monitors in clinical use of ICU,cardiovascular intensive care unit(CCU)and neurosurgery intensive care unit(NICU)of Hainan General Hospital from October 14 to December 27,2024 were selected.According to the opening and close of the four-lead ECG synchronization and multi-parameter fusion technique algorithm of the monitors,they were divided into group A(opened four-lead ECG synchronization and multi-parameter fusion),group B(opened four-lead ECG synchronization,but closed multi-parameter fusion),group C(closed four-lead ECG synchronization,but opened multi-parameter fusion)and group D(closed four-lead ECG synchronization and multi-parameter fusion),with 12 units in each group.The numbers of total alarms and false alarms generated by monitor of each bed unit among different optimization strategies were compared.Results:The numbers of average daily alarm of the monitors in groups A,B and C were respectively(134.2±32.4)cases,(392.5±68.2)cases and(583.4±126.5)cases,which were lower than those in group D(1 073.2±168.6),with statistically significant differences(Z=3.45,2.94,2.52,P<0.05).The optimization rates of the alarm numbers in groups A,B and C were increased by 87.51%,63.47%and 45.67%,respectively.The rates of average false alarm of the monitors in groups A,B and C were respectively(1.04±0.15)%,(1.73±0.12)%and(2.07±0.08)%,which were lower than(3.76±0.2)%in group D,with statistically significant differences(Z=3.45,2.94,2.52,P<0.05).Conclusion:Four-lead ECG synchronization technique and multi-parameter fusion technique can effectively optimize the number of alarms in ICU,and reduce the proportion of false alarms of monitors in department,and decrease fatigue of medical staffs for alarm.

Objective:To explore the clinical efficacy of the splenic vessel-oriented anatomical plane priority strategy in Da Vinci robotic Kimura distal pancreatectomy.Methods:A retrospective analysis was conducted on 26 patients who underwent robotic-assisted distal pancreatectomy at Zhejiang Provincial People’s Hospital from January 2019 to September 2024. The cohort included 7 male and 19 female patients, aged (49.3±16.7) years. Surgical outcomes, including operative time, intraoperative blood loss, postoperative complications, and hospital stay, were analyzed, and surgical techniques were summarized.Results:All 26 patients successfully completed the surgery. Pathological diagnoses included 5 cases of intraductal papillary mucinous neoplasm, 5 serous cystadenomas, 1 pancreatic neuroendocrine tumor, 6 solid pseudopapillary neoplasms, 4 mucinous cystic neoplasms, and 5 neuroendocrine tumors. The maximum tumor diameter was (2.3±1.1) cm, and the operative time was (183.2±77.4) min. The spleen preservation rate was 100% (26/26). Intraoperative blood loss was 50.0 (17.5, 125) ml, and postoperative hospital stay was (10.1±3.7) d. No Clavien-Dindo grade III or higher complications occurred. The post-operative pancreatic fistula (POPF) rate was 53.8% (14/26), including 38.5% (10/26) biochemical leak and 15.3% (4/26) grade B POPF, with no grade C POPF.Conclusion:The splenic vessel-oriented anatomical plane priority strategy in robotic-assisted spleen-preserving distal pancreatectomy (Kimura technique) is safe and feasible, significantly improving the spleen preservation rate.

Objective:To evaluate the clinical efficacy of individualized postural management guided by lung ultrasound (LUS) in neonates with grade Ⅲ bronchopulmonary dysplasia (BPD).Methods:This prospective randomized controlled trial enrolled neonates diagnosed with grade Ⅲ BPD at Guangdong Second People's Hospital Affiliated to Jinan University from July 2022 to December 2024, who were randomly assigned to control or intervention groups. The control group received conventional postural management (head elevation 15°-30°, supine-left lateral-right lateral-prone positioning with 2-hour rotations), while the intervention group underwent additional LUS examinations every 12 hours for dynamic posture adjustment based on pulmonary findings. Outcomes included LUS signs (pleural line abnormalities, A-line disappearance, B-line increases, cystic hyperaeration, alveolar-interstitial syndrome, consolidation) and primary endpoints (post-diagnosis oxygen therapy duration, invasive mechanical ventilation duration, and hospital stay). Secondary outcomes comprised new complications (pulmonary hemorrhage, necrotizing enterocolitis, BPD-associated pulmonary hypertension, grade Ⅲ-Ⅳ intracranial hemorrhage, retinopathy of prematurity). Intergroup comparisons used two independent samples t-tests and Chi square tests. Results:Among 49 eligible neonates, 47 were randomized (intervention group=24; control group=23), with 40 completing the study (20 per group after exclusions). At day 7, the intervention group showed significantly lower rates of pleural line abnormalities [55% (11/20) vs. 90% (18/20), χ2=6.14, P=0.013], A-line disappearance [50% (10/20) vs. 80% (16/20), χ2=3.95, P=0.046], B-line increases [50% (10/20) vs. 85% (17/20), χ2=5.58, P=0.018], alveolar-interstitial syndrome [65% (13/20) vs. 95% (19/20), χ2=5.62, P=0.017], and consolidation [50% (10/20) vs. 80% (16/20), χ2=3.95, P=0.046]. The intervention group also demonstrated shorter invasive ventilation [(9.5±2.3) vs. (11.6±3.5) days, t=2.18, P=0.035] and hospital stay [(58.9±4.9) vs. (63.2±6.4) days, t=2.33, P=0.025] post-diagnosis, with no significant differences in new complication rates (all P>0.05). Conclusion:LUS-guided postural management improves pulmonary pathology, reduces respiratory support duration and hospitalization, without increasing complications in grade Ⅲ BPD neonates.

BACKGROUND:Previous studies have found that neohesperidin can delay bone loss in ovariectomized mice and has the potential to treat osteoporosis,but its specific mechanism of action remains to be explored. OBJECTIVE:To explore the key targets and possible mechanisms of neohesperidin in the treatment of osteoporosis based on bioinformatics and cell experiments in vitro. METHODS:The gene expression dataset related to osteoporosis was obtained from GEO database,and the differentially expressed genes were screened and analyzed in R language.The osteoporosis-related targets were screened from GeneCards and DisGeNET databases,and the neohesperidin-related targets were screened from ChEMBL and PubChem databases,and the common targets were obtained by intersection of the three.The String database was used to construct the PPI network of intersection genes,and the key targets were screened.The DAVID database was used for GO and KEGG enrichment analysis.The AutoDock software was used to verify the molecular docking between the neohesperidin and the target protein.The effect of neohesperidin on osteogenic differentiation of C57 mouse bone marrow mesenchymal stem cells was detected.Complete medium was used as blank control group;osteogenic induction medium was used as the control group;and osteogenic induction medium containing different concentrations of neohesperidin(25,50 μmol/L)was used as experimental group.The expression of alkaline phosphatase,the degree of mineralization,the expression of osteogenic-related genes and target genes during osteogenic differentiation of cells were measured at corresponding time points. RESULTS AND CONCLUSION:(1)9 253 differentially expressed genes,2 161 osteoporosis-related targets,and 326 neohesperidin-related targets were screened.There were 53 common targets among the three.All 53 genes were up-regulated in osteoporosis samples.The PPI network screened the target gene PRKACA of research significance.GO function and KEGG pathway enrichment analysis showed that neohesperidin's treatment of osteoporosis through PRKACA target mainly depended on biological processes such as protein phosphorylation and protein autophosphorylation,acting on endocrine resistance,proteoglycan in cancer,and estrogen signaling pathway to play a therapeutic role.Molecular docking results showed that neohesperidin had a certain binding ability to the protein corresponding to the target PRKACA.(2)The results of alkaline phosphatase staining showed that neohesperidin could promote the expression of alkaline phosphatase in the early stage of osteogenic differentiation of mesenchymal stem cells.Alizarin red staining showed that neohesperidin could promote the mineralization of osteogenic differentiation of mesenchymal stem cells.RT-qPCR results showed that neohesperidin could increase the mRNA expression of alkaline phosphatase,PRKACA,and osteocalcin.(3)These results indicate that neohesperidin may promote osteogenic differentiation through PRKACA target on the estrogen signaling pathway to prevent and treat osteoporosis.

ObjectiveTo investigate the mechanism of Forsythiae Fructus-Lonicerae Japonicae Flos（FF） in the treatment of acute lung injury（ALI） by investigating the effects of FF on serum metabolomics of rats with ALI. MethodsThirty male SD rats were acclimated for 1 week， and 6 rats were randomly selected as the blank group. The other 24 rats were injected with lipopolysaccharide（LPS） solution by tracheal drip to establish an ALI model. After successful model establishment， the rats were randomly divided into the model group， the FF low-dose group（3.0 g·kg^-1）， the FF high-dose group（6.0 g·kg^-1）， and the dexamethasone group（5 mg·kg^-1）， with six rats in each group. The FF low- and high-dose groups and the dexamethasone group were received daily oral administration of the corresponding drug solution， and the blank group and the model group were gavaged with an equal amount of saline， treatment was administered continuously for 3 d. The pathological conditions of rat lung tissues were evaluated by hematoxylin-eosin（HE） staining， wet/dry mass ratio（W/D） of the lung tissues， and protein concentration in rat bronchoalveolar lavage fluid（BALF）. Metabolomic analysis of rat serum was performed by ultra-performance liquid chromatography-quadrupole-time-of-flight mass spectrometry（UPLC-Q-TOF-MS）， combined with multivariate statistical analysis， the potential biomarkers of FF in treating ALI were screened by variable importance in the projection（VIP） value>1， P<0.05 from t-test， and log₂fold change（FC）>1 or log₂FC<-1. Kyoto Encyclopedia of Genes and Genomes（KEGG） database combined with MetaboAnalyst were used for pathway analysis of the screened differential metabolites. The protein expression levels of sphingosine-1-phosphate（S1P）， phosphatidylinositol 3-kinase（PI3K）， protein kinase B1（Akt1）， and phosphorylated Akt1（p-Akt1） were examined by Western bolt. The expression levels of interleukin（IL）-6， IL-1β， and tumor necrosis factor（TNF）-α in BALF were detected by enzyme-linked immunosorbent assay（ELISA）. ResultsCompared with the blank group， rats in the model group showed ALI pathological features such as alveolar lumen dilatation， interstitial hemorrhage and massive inflammatory cell infiltration， and the protein concentration in BALF and W/D of the lung tissues were significantly elevated（P<0.01）. Compared with the model group， the low- and high-dose groups of FF as well as the dexamethasone group exhibited reduced pulmonary bronchial hemorrhage in rats， and the protein concentration in BALF and W/D were significantly decreased（P<0.05）， and the lung injury was significantly alleviated. Analysis of rat serum metabolomics revealed that FF downregulated 38 biomarkers. Pathway enrichment analysis showed that FF primarily exerted therapeutic effects through 7 key metabolic pathways， including arginine biosynthesis， sphingomyelin metabolism， alanine， aspartate and glutamate metabolism， taurine and hypotaurine metabolism， α-linolenic acid metabolism， niacin and nicotinamide metabolism， and retinol metabolism. The results of Western bolt and ELISA showed that， compared with the blank group， the model group exhibited significantly elevated expression levels of S1P， PI3K， Akt1 and p-Akt1 proteins in the lung tissues， as well as increased expression levels of IL-6， IL-1β and TNF-α in BALF（P<0.01）. Compared with the model group， the expression levels of the aforementioned indicators were significantly downregulated in the low- and high-dose FF groups as well as the dexamethasone group（P<0.05， P<0.01）. ConclusionFF may play a role in ALI by regulating amino acid metabolism and lipid metabolism， and its mechanism may be related to the inhibition of S1P/PI3K/Akt1 signaling pathway to attenuate the inflammatory response caused by ALI.

Background::An evidence gap still exists regarding the efficacy and safety of tegoprazan in patients with erosive esophagitis (EE) in China. This study aimed to verify the efficacy and safety of tegoprazan vs. esomeprazole in patients with EE in China. Methods::This study was a multicenter, randomized, double-blind, parallel, active-controlled, non-inferiority phase III trial of patients with EE randomized 1:1 to tegoprazan 50 mg/day vs. esomeprazole 40 mg/day. This study was conducted in 32 sites between October 24, 2018 and October 18, 2019. The primary endpoint was the cumulative endoscopic healing rate at week 8. The secondary endpoint included endoscopic healing rate at week 4, changes in the reflux disease questionnaire (RDQ) and gastroesophageal reflux disease health-related quality of life (GERD-HRQL) scores, and symptom improvement. Results::A total of 261 patients were randomized: 132 to the tegoprazan group and 129 to the esomeprazole group. The cumulative endoscopic healing rate at 8 weeks in the tegoprazan group was non-inferior to that of the esomeprazole group (91.1% vs. 92.8%, difference: -1.7%, 95% confidence interval [CI]: -8.5%, 5.0%, P = 0.008). There were no statistically significant differences in the changes in RDQ (total, severity, and frequency) and GERD-HRQL scores between the two groups (all P >0.05). The percentages of days without symptoms, including daytime and nighttime symptoms based on patients' diaries, were similar between the two groups (all P >0.05). In the tegoprazan and esomeprazole groups, 71.5% (93/130) and 61.7% (79/128) of the participants reported adverse events (AEs), 2.3% and 0 experienced serious AEs, while 70.0% and 60.2% had treatment-emergent AEs, respectively. Conclusion::Tegoprazan 50 mg/day demonstrated non-inferior efficacy in healing EE, symptom improvement, and quality of life, and it has similar tolerability compared with esomeprazole 40 mg/day.
