ObjectiveTo explore the effectiveness and safety of Shenlong Dingji Formula （参龙定悸方） on the quality of life in patients with paroxysmal atrial fibrillation （PAF） of qi-yin deficiency and phlegm-stasis obstructing collaterals syndrome. MethodsA total of 60 patients with PAF of qi-yin deficiency and phlegm-stasis obstructing collaterals syndrome were recruited and randomly divided into a treatment group and a control group， with 30 patients in each group. The control group received standard western medicine treatment， while the treatment group was additionally given Shenlong Dingji Formula orally， one dose per day. Both groups were treated for 4 weeks. The primary outcome measure is the Atrial Fibrillation Effect on Quality of Life （AFEQT） score including scores of four dimensions，i.e. atrial fibrillation-related symptoms， treatment concerns， daily activities， and treatment satisfaction. The secondary outcome measures included the frequency and duration of symptomatic atrial fibrillation episodes and traditional Chinese medicine （TCM） syndrome scores covering symptoms such as palpitations， chest tightness， fatigue， shortness of breath， reluctance to speak， spontaneous sweating， stabbing pain， and insomnia. These indicators were assessed at baseline （before treatment）， after 2-week of treatment， after 4-week of treatment， and 4 weeks after the end of treatment （follow-up）. Additionally， safety indicators before and after treatment and adverse events occurring during the trial were recorded to evaluate safety. ResultsA total of 56 patients completed the study， with 28 in each group. Primary outcome indicators： 1） the treatment group showed significant improvement in the total score of the AFEQT scale， with significantly higher total scores after 2-week treatment， 4-week treatment， and follow-up compared to the previous time point （P＜0.05）. In the control group， the AFEQT score significantly increased only after 4-week treatment compared to baseline （P＜0.05）. In the treatment group， the AFEQT scores after 2-week， 4-week treatment， and during follow-up were all higher than those of the control group at the corresponding time points （P＜0.01）. 2） In the treatment group， there was no statistically significant difference in the AFEQT treatment satisfaction dimension score during follow-up compared to that after 4-week treatment （P＞0.05）. However， the scores for all other dimensions at each time point were higher than those at the previous time point （P＜0.05）. In the control group， the scores for the atrial fibrillation-related symptom dimension were higher after 2-week and 4-week treatment than those of the previous time points （P＜0.05）. For the treatment satisfaction dimension， significant increases were observed only after 2-week and 4-week treatment compared to baseline （P＜0.05）. Secondary outcome indicators： 1） In the treatment group， the frequency and duration of symptomatic atrial fibrillation episodes decreased significantly at each time point compared to the previous time point （P＜0.05）， except for the duration of trial fibrillation at follow-up. In the control group， the frequency of episodes decreased significantly at all time points compared to baseline （P＜0.05）， while the duration of trial fibrillation showed a significant reduction at follow-up compared to those after 2-week treatment （P＜0.05）. 2） In the treatment group， TCM syndrome scores significantly reduced after 2-week treatment， 4-week treatment， and during follow-up compared to the previous time point and baseline （P＜0.05）. In the control group， significant reductions were observed only after 4-week after treatment and during follow-up （P＜0.05）. The TCM syndrome scores in the treatment group were lower than those in the control group at the same time points （P＜0.01）. No adverse events occurred during the trial in either group， and safety indicators showed no significant changes after treatment. ConclusionShenlong Dingji Formula effectively improves the quality of life， alleviates TCM syndromes， and reduces the frequency and duration of symptomatic atrial fibrillation in patients with PAF of qi-yin deficiency and phlegm-stasis obstructing collaterals syndrome， and demonstrates good safety.

Objective To discuss the application of gelatin sponge-hemocoagulase plugging agent in patients with pulmonary puncture bleeding.Methods The clinical data of 43 patients with hemorrhage caused by DSA-guided lung puncture biopsy,who received gelatin sponge-hemocoagulase plugging agent treatment at the Jining Municipal First People's Hospital of China between September 2021 and May 2023,were collected,and the hemostatic effect of gelatin sponge-hemocoagulase plugging agent was analyzed.Results Successful lung puncture needle biopsy was achieved in all the 43 patients.The puncture needle channel occlusion was accomplished by using gelatin sponge-hemocoagulase plugging agent.Five minutes after occlusion treatment,in one patient,whose moderate hemoptysis with moderate bleeding shadow before puncture needle biopsy changed to bloody sputum,the intrapulmonary bleeding shadow displayed on image became slightly enlarged when compared the size five minutes ago,while in all the remaining patients successful hemostasis was achieved,the hemoptysis disappeared and the pulmonary hemorrhage shadow was similar to that five minutes ago.No occlusion-related complications occurred in all patients.Conclusion For the treatment of pulmonary hemorrhage caused by DSA-guided lung puncture biopsy,gelatin sponge-hemocoagulase plugging agent is clinically safe and effective.

BackgroundPatients after percutaneous coronary intervention （PCI） are prone to experience depression， which has been shown to significantly affect patients' quality of recovery in postoperative period. Resourcefulness plays an important role between stress and depression， yet there is insufficient research evidence on the predictive effect of intellectual resourcefulness levels on depressive symptoms among patients undergoing PCI. ObjectiveTo investigate the cross-lagged effect between level of resourcefulness and depressive symptoms among patients after PCI， so as to provide references for alleviating depressive symptoms in patients after PCI. MethodsA total of 363 patients who had undergone PCI in Tangshan Gongren Hospital from September to December 2019 were selected using random sampling technique. All participants were subjected to complete Chinese Resourcefulness Scale （CRS） and Chinese version of Cardiac Depression Scale （C-CDS） at both baseline and two years after PCI. A structural equation model was constructed to determine the cross-lagged effect between the level of resourcefulness and depressive symptoms in patients. ResultsMale patients scored higher on CRS （t=-19.871， P<0.01） and lower on C-CDS （t=25.557， P<0.01） after two years of PCI compared with female patients after PCI. Correlation analysis indicated that the baseline CRS score was positively correlated with two years after PCI CRS score （r=0.550， P<0.01）， C-CDS score of baseline was positively correlated with two years after PCI C-CDS score （r=0.524， P<0.01）， baseline CRS score was negatively correlated with C-CDS scores at both baseline （r=-0.717， P<0.01） and two years after PCI （r=-0.472， P<0.01）， and two years after PCI， CRS score was negatively correlation with C-CDS score （r=-0.618， P<0.01）. The cross-lagged analysis revealed that baseline CRS score significantly predicted CRS score of two years after PCI （β=0.382， P<0.01） and C-CDS score of two years after PCI （β=-0.200， P<0.01）. Baseline C-CDS score significantly predicted C-CDS score of two years after PCI （β=0.381， P<0.01） and CRS score of two years after PCI （β=-0.235， P<0.01）. There was a reciprocal relationship between baseline CRS score and baseline C-CDS score （β=-0.717， P<0.01）. ConclusionThe established cross-lagged model yields the presence of a reciprocal prediction of level of resourcefulness and depressive symptoms measured in patients at two time points. The higher the baseline level of resourcefulness， the lighter the depressive symptoms experienced by patients two years after PCI surgery.The more severe the baseline depressive symptoms， the lower the patients' level of resourcefulness two years after PCI surgery.［Funded by Project of Hebei Provincial Department of Science and Technology （number， 182777154）］

Objective To evaluate the efficacy and safety of brexpiprazole in treating acute schizophrenia.Methods Patients with schizophrenia were randomly divided into treatment group and control group.The treatment group was given brexpiprozole 2-4 mg·d-1 orally and the control group was given aripiprazole 10-20 mg·d-1orally,both were treated for 6 weeks.Clinical efficacy of the two groups,the response rate at endpoint,the changes from baseline to endpoint of Positive and Negative Syndrome Scale(PANSS),Clinical Global Impression-Improvement(CGI-S),Personal and Social Performance scale(PSP),PANSS Positive syndrome subscale,PANSS negative syndrome subscale were compared.The incidence of treatment-related adverse events in two groups were compared.Results There were 184 patients in treatment group and 186 patients in control group.After treatment,the response rates of treatment group and control group were 79.50％(140 cases/184 cases)and 82.40％(150 cases/186 cases),the scores of CGI-I of treatment group and control group were(2.00±1.20)and(1.90±1.01),with no significant difference(all P＞0.05).From baseline to Week 6,the mean change of PANSS total score wese(-30.70±16.96)points in treatment group and(-32.20±17.00)points in control group,with no significant difference(P＞0.05).The changes of CGI-S scores in treatment group and control group were(-2.00±1.27)and(-1.90±1.22)points,PSP scores were(18.80±14.77)and(19.20±14.55)points,PANSS positive syndrome scores were(-10.30±5.93)and(-10.80±5.81)points,PANSS negative syndrome scores were(-6.80±5.98)and(-7.30±5.15)points,with no significant difference(P＞0.05).There was no significant difference in the incidence of treatment-related adverse events between the two group(69.00％vs.64.50％,P＞0.05).Conclusion The non-inferiority of Brexpiprazole to aripiprazole was established,with comparable efficacy and acceptability.

Objective To evaluate the application of three deep learning algorithms in automatic segmentation of clinical target volumes (CTVs) in high-dose-rate brachytherapy after surgery for endometrial carcinoma. Methods A dataset comprising computed tomography scans from 306 post-surgery patients with endometrial carcinoma was divided into three subsets: 246 cases for training, 30 cases for validation, and 30 cases for testing. Three deep convolutional neural network models, 3D U-Net, 3D Res U-Net, and V-Net, were compared for CTV segmentation. Several commonly used quantitative metrics were employed, i.e., Dice similarity coefficient, Hausdorff distance, 95th percentile of Hausdorff distance, and Intersection over Union. Results During the testing phase, CTV segmentation with 3D U-Net, 3D Res U-Net, and V-Net showed a mean Dice similarity coefficient of 0.90 ± 0.07, 0.95 ± 0.06, and 0.95 ± 0.06, a mean Hausdorff distance of 2.51 ± 1.70, 0.96 ± 1.01, and 0.98 ± 0.95 mm, a mean 95th percentile of Hausdorff distance of 1.33 ± 1.02, 0.65 ± 0.91, and 0.40 ± 0.72 mm, and a mean Intersection over Union of 0.85 ± 0.11, 0.91 ± 0.09, and 0.92 ± 0.09, respectively. Segmentation based on V-Net was similarly to that performed by experienced radiation oncologists. The CTV segmentation time was < 3.2 s, which could save the work time of clinicians. Conclusion V-Net is better than other models in CTV segmentation as indicated by quantitative metrics and clinician assessment. Additionally, the method is highly consistent with the ground truth, reducing inter-doctor variability and treatment time.

Coronary perforation is when a contrast agent or blood flows outside a blood vessel through a tear in a coronary artery.In this case,we reported a case of percutaneous coronary intervention for coronary calcified lesions,which led to iatrogenic coronary perforation and cardiac tamponade after the use of Shockwave balloon to treat intracoronary calcified nodules,and the management of PCI-related CAP was systematically reviewed through the literature.

Objective To analyze the safety and efficacy of neuroendoscopic minimally invasive surgery and traditional extraventricular drainage in the treatment of severe hypertensive intraventricular hemorrhage.Methods The clinical data of 50 cases with neuroendoscopic ventricular hematoma evacuation(endoscopy group)and 44 cases with traditional ventricles external puncture drainage(drainage group)from July 2020 to July 2023 were retrospectively analyzed,and the hematoma clearance rates,classification of activities of daily living(ADL)scale,incidence of hydrocephalus,secondary bleeding,intracranial infection,and pulmonary infection were observed between the two groups of patients.Results After surgery,the proportion of patients with hematoma clearance rate>60％and ADL grades Ⅰ,Ⅱ,and Ⅲ in the endoscopy group were significantly higher than those in the drainage group[the proportion of patients with hematoma clearance rate>60％:88.0％(44/50)vs.47.7％(21/44),χ2=17.794,P<0.001;the proportion of individuals with ADL grades Ⅰ,Ⅱ,and Ⅲ:94.0％(47/50)vs.77.3％(33/44),respectively,χ2=5.459,P=0.019],the incidence of complications in endoscopy group was significantly lower in the drainage group[8.0％(4/50)vs.34.1％(15/44),χ2=9.879,P=0.002].Conclusion Compared with traditional ventricular puncture drainage surgery,neuroendoscopic minimally invasive surgery for the treatment of severe hypertensive intracerebral hemorrhage with ventricular casting can achieve better treatment outcomes,a higher hematoma clearance rate,and fewer postoperative complications.

Objective:To explore the effects of hypoxia on traumatic brain swelling (TBS) in rats with acute subdural hematoma (ASDH).Methods:Forty-five SD rats were divided into 5 groups according to the random number table method, with 9 rats in each group: sham surgery normal oxygen group which underwent sham surgical procedures and were placed in a closed container with ventilation, sham surgery hypoxia group which underwent sham surgical procedures and were placed in a closed container with oxygen volume fraction of 8% for hypoxia induction, ASDH normal oxygen group which made into the ASDH model and placed in a closed container with ventilation, ASDH hypoxia group were made into the ASDH models and placed in a closed container with oxygen volume fraction of 8% for hypoxia induction, and ASDH hypoxia+oxygen inhalation group which inhaled oxygen continuously with oxygen volume fraction of 40% after being made into the ASDH models and induced for hypoxia. Six rats were selected from each group immediately after the modeling and craniotomy was performed to observe the brain swelling during the surgery and evaluate the degree of TBS. Microvascular blood flow was observed by laser speckle imaging system before modeling, before craniotomy, and immediately after craniotomy. The remaining 3 rats in each group were killed directly after modeling and brain tissue specimens were collected. The expression levels of pericellular protein α-smooth muscle actin (α-SMA) and platelet-derived growth factor receptor-β (PDGFR-β) at 0, 30 and 60 minutes after modeling were detected through Western blot analysis. The expression levels of α-SMA, PDGFR-β and microvascular marker platelet-endothelial cell adhesion molecule 31 (CD31) at 0 minute after modeling were tested through immunofluorescent staining.Results:No brain bulge was observed in the sham surgery normal oxygen group. The height of brain bulge in sham surgery hypoxia group was 0.5(0.0, 1.0)mm, with no significant difference from that in the sham surgery normal oxygen group ( P>0.05); it was 2.2(2, 2.5)mm in the ASDH normal oxygen group, significantly higher than that in the sham surgery normal oxygen group and sham surgery hypoxia group ( P<0.01), it was 3.1(2.9, 3.2)mm in the ASDH hypoxia group, significantly higher than that in the sham surgery normal oxygen group, sham surgery hypoxia group and ASDH normal oxygen group ( P<0.01); it was 2.8(2.7, 2.9)mm in the ASDH hypoxia+oxygen inhalation group, not statistically different from that in the ASDH hypoxia group ( P>0.05), but significantly increased compared with that in the sham surgery normal oxygen group, sham surgery hypoxia group and ASDH normal oxygen group ( P<0.01). Before modeling, before craniotomy and after craniotomy, the microvascular blood flow was 224.2±49.7, 224.8±50.3, 225.1±50.3 respectively in the sham surgery normal oxygen group and 224.7±43.7, 220.9±45.9, 221.8±45.5 respectively in the sham surgery hypoxia group, with no significant difference between the two groups ( P>0.05); it was 226.5±52.7, 173.4±40.7, 172.0±40.7 respectively in the ASDH normal oxygen group, significantly decreased compared with that in the sham surgery normal oxygen group and sham surgery hypoxia group ( P<0.05); it was 225.7±46.4, 131.4±23.6 and 131.0±23.5 respectively in the ASDH hypoxia group, significantly decreased compared with that in the sham surgery normal oxygen group, sham surgery hypoxia group and ASDH normal oxygen group ( P<0.05); it was 226.2±56.1, 132.6±21.7 and 131.7±21.9 respectively in ASDH hypoxia+oxygen inhalation group, significantly decreased compared with that in the sham surgery normal oxygen group, sham surgery hypoxia group and ASDH normal oxygen group ( P<0.05), with no significant difference from that in the ASDH hypoxia group ( P>0.05). At 0, 30 and 60 minutes after modeling, the expression levels of α-SMA and PDGFR-β were 0.70±0.02, 0.67±0.01, 0.55±0.05 and 0.65±0.03, 0.56±0.03 and 0.59±0.02 respectively in the sham surgery normal oxygen group and were 0.63±0.04, 0.60±0.01 0.55±0.05 and 0.62±0.01, 0.51±0.01 and 0.60±0.02 respectively in the sham surgery hypoxia group, with no significant difference between the two groups ( P>0.05); they were 0.88±0.06, 0.87±0.05, 0.82±0.03 and 0.85±0.03, 0.85±0.03, 0.88±0.04 respectively in the ASDH normal oxygen group, significantly higher than those in the sham surgery normal oxygen group and sham surgery hypoxia group ( P<0.01); they were 1.19±0.08, 1.10±0.10, 0.97±0.04 and 1.04±0.06, 1.19±0.07, 1.27±0.08 respectively in the ASDH hypoxia group, significantly higher than those in sham surgery normal oxygen group, sham surgery hypoxia group and ASDH normal oxygen group ( P<0.05 or 0.01); they were 1.20±0.07, 1.10±0.04, 0.96±0.04 and 1.04±0.05, 1.15±0.11, 1.20±0.07 respectively in ASDH hypoxia+oxygen inhalation group, significantly higher than those in sham surgery normal oxygen group, sham surgery normal group and ASDH normal oxygen group ( P<0.01), but with no significant difference from those in ASDH hypoxia group ( P>0.05). At 0 minute after modeling, the fluorescence expression of α-SMA and PDGFR-β was weaker in the sham surgery normal oxygen group and the fluorescence expression of CD31 was stronger. There was no significant difference in the fluorescence expressions of α-SMA, PDGFR-β and CD31 between the sham surgery hypoxia group and sham surgery normal oxygen group. The fluorescence expressions of α-SMA and PDGFR-β in the ASDH normal oxygen group were stronger than those in the sham surgery normal oxygen group and sham surgery hypoxia group, while the fluorescence expression of CD31 was weaker. The fluorescence expressions of α-SMA and PDGFR-β in ASDH hypoxia group were stronger than those in the sham surgery normal oxygen group, sham surgery hypoxia group and ASDH normal oxygen group, while the fluorescence expression of CD31 was weaker. The fluorescence expressions of α-SMA and PDGFR-β in the ASDH hypoxia+oxygen inhalation group were stronger than those in the sham surgery normal oxygen group, sham surgery hypoxia group and ASDH normal oxygen group, while the fluorescence expression of CD31 was weaker, with no significant difference from the fluorescence expressions of α-SMA, PDGFR-β and CD31 in ASDH hypoxia group. Conclusions:Hypoxia in ASDH rats will stimulate pericytes contraction, which causes cerebral microcirculatory disturbance, thus leading to TBS. Short-term inhalation of oxygen of medium concentration cannot dilate pericytes or microcirculation vessels, with no obvious effect on improving the conditions of TBS.

Objective To investigate the risk factors for bronchopulmonary dysplasia(BPD)in twin preterm infants with a gestational age of<34 weeks,and to provide a basis for early identification of BPD in twin preterm infants in clinical practice.Methods A retrospective analysis was performed for the twin preterm infants with a gestational age of<34 weeks who were admitted to 22 hospitals nationwide from January 2018 to December 2020.According to their conditions,they were divided into group A(both twins had BPD),group B(only one twin had BPD),and group C(neither twin had BPD).The risk factors for BPD in twin preterm infants were analyzed.Further analysis was conducted on group B to investigate the postnatal risk factors for BPD within twins.Results A total of 904 pairs of twins with a gestational age of<34 weeks were included in this study.The multivariate logistic regression analysis showed that compared with group C,birth weight discordance of>25%between the twins was an independent risk factor for BPD in one of the twins(OR=3.370,95%CI:1.500-7.568,P<0.05),and high gestational age at birth was a protective factor against BPD(P<0.05).The conditional logistic regression analysis of group B showed that small-for-gestational-age(SGA)birth was an independent risk factor for BPD in individual twins(OR=5.017,95%CI:1.040-24.190,P<0.05).Conclusions The development of BPD in twin preterm infants is associated with gestational age,birth weight discordance between the twins,and SGA birth.

Objective To explore the influencing factors of microcirculation dysfunction in patients with anterior wall acute myocardial infarction(AMI)and to establish a relevant prediction model.Methods A total of 130 patients with anterior wall AMI,whose microcirculation function was assessed by caIMR after receiving percutaneous coronary intervention(PCI)at Shanghai Sixth People's Hospital of China from January 2017 to September 2020,were enrolled in this study.The patients were divided into abnormal microcirculation resistance group(n=52)and normal microcirculation resistance group(n=78).The clinical data were compared between the two groups.The regression analysis was used to analyze the influencing factors of microcirculation dysfunction.Results In the abnormal microcirculation resistance group the contrast agent consumption,the onset-to-operation time,the Gensini total score and the LAD Gensini score were(121.92±31.37)mL,(10.51±5.12)min,(97.91±31.77)points and(69.36±13.15)points respectively,which were significantly higher than(109.03±28.2)mL,(4.94±2.94)min,(81.05±35.22)points and(54.45±23.48)points respectively in the normal microcirculation resistance group,the differences in the above indexes between the two groups were statistically significant(all P＜0.05).A prediction model covering interventional strategies was established,and its accuracy was higher than that of a conventional model,its AUC compared with the conventional model was 0.91 to 0.87,indicating that this model could well predict the risk of microcirculation dysfunction in patients with AMI after receiving PCI.Conclusion This prediction model can promptly identify high-risk microcirculation dysfunction patients with anterior wall AMI after receiving PCI.
