The existing epilepsy seizure detection algorithms have problems such as overfitting and poor generalization ability due to high reliance on manual labeling of electroencephalogram's data and data imbalance between seizure and interictal periods. An unsupervised learning detection method for epileptic seizure that jointed graph attention network (GAT) and Transformer framework (GAT-T) was proposed. In this method, channel correlations were adaptively learned by GAT encoder. Temporal information was captured by one-dimensional convolution decoder. Combining outputs of the two mentioned above, predicted values for electroencephalogram were generated. The collective anomaly score was calculated and the detection threshold was determined. The results demonstrated that GAT-T achieved the average performance exceeding 90% (or 99%) with a 0.25 s (or 2 s) time segment length, which could effectively detect epileptic seizures. Moreover, the channel association probability matrix was expected to assist clinicians in the initial screening of the epileptogenic zone, and ablation experiments also reflected the significance of each module in GAT-T. This study may assist clinicians in making more accurate diagnostic and therapeutic decisions for epilepsy patients.

Objective To analyze the methodology and reporting quality of acupuncture related randomized controlled trials(RCTs)in order to provide a basis for improving the design and reporting of acupuncture studies.Methods Literatures on RCTs included in acupuncture were obtained from two systematic reviews of acupuncture studies.Two reviewers were selected independently according to the exclusion criteria,and RoB2.0,CONSORT statement and STRICTA criteria were used to evaluate the methodology and report quality.Results 95 literatures on acupuncture RCTs were included,including 51 in Chinese and 44 in English,involving 38 diseases and 54 outcome indicators.CONSORT declared that there were 8 items with high reporting rate,15 items with low reporting rate and 2 items with medium reporting rate in the evaluation.The STRICTA criteria included 8 items with high reporting rate,4 items with low reporting rate,and 4 items with medium reporting rate.As for RoB2.0 bias risk assessment,11.6%of the literature in the overall bias area that served as a summary was high risk,50.5%was likely risk,and 37.9%was low risk.Conclusion The current published RCTs research methodology and report quality evaluation are not high,the future research should improve the scientific and rigorous program design,to form a transparent and complete research report.

This article reports a case of peritoneal dialysis (PD)-associated peritonitis caused by Streptococcus dysgalactiae subspecies dysgalactiae. The patient was an elderly female with a previous diagnosis of anti-neutrophil cytoplasmic antibody-associated vasculitis with renal involvement and chronic kidney disease stage 5. She had been receiving regular PD therapy for 8 years. She was admitted to the hospital due to abdominal pain and cloudy peritoneal dialysate for 10 hours, and the peritoneal dialysate culture result was positive for Streptococcus dysgalactiae subspecies dysgalactiae. She was treated with intraperitoneal vancomycin and intravenous ampicillin for anti-infection, but the therapeutic effect was poor. Therefore, the PD catheter was removed and the patient was discharged after the condition was improved.

Objectives:To investigate the intravascular ultrasound(IVUS)evaluated efficacy of the"L-sandwich"technique in the percutaneous coronary intervention treatment of true bifurcation lesions of coronary artery. Methods:Ninety-nine patients with true bifurcation lesions(medina type 1.1.1)of the coronary arteries were divided into the L-sandwich group(n=38),the double-stent group(n=32),and the main vessel(MV)single-stent with side branch(SB)drug-coated balloon(DCB)only group(n=29).The primary study endpoint was the loss of late lumen area(LLAL)in the MV,SB ostium and SB shaft at 12 months,and the secondary endpoints were minimum lumen area(MLA)at each site and major adverse cardiac events(MACE)at 12 months.As this is a proof-of-concept study,statistical analyses were performed in the as-treated(AT)analysis set. Results:At 12-month follow-up,there was no statistically significant difference in the MV LLAL among patients in the"L-sandwich"technique group,the double stent technique group,and the MV DES with SB DCB technique group([0.12±0.42]mm2 vs.[0.07±0.38]mm2 vs.[-0.01±0.31]mm2,P=0.419).Similarly,there was no statistically significant difference in the LLAL at the SB shaft([-0.11±0.45]mm2 vs.[-0.10±0.28]mm2 vs.[0.24±1.04]mm2,P=0.078],with the maximum LLAL observed in the double stent technique group and the minimum in the"L-sandwich"technique group([-0.48±0.78]mm2 vs.[0.45±0.64]mm2 vs.[0.14±1.37]mm2,P<0.001).The MV MLA was similar among the three groups([8.39±1.65]mm2 vs.[8.28±0.98]mm2 vs.[8.02±1.37]mm2,P=0.565),while the maximum MLA at the SB ostium was observed in the double stent technique group and the minimum in the MV DES with SB DCB group([5.08±0.74]mm2 vs.[5.63±0.80]mm2 vs.[3.57±1.35]mm2,P<0.001).In terms of MLA at the SB shaft,the"L-sandwich"technique group was similar to the double stent technique group,while the MV DES with SB DCB group exhibited the minimum MLA([5.94±0.72]mm2 vs.[5.86±0.59]mm2 vs.[3.74±1.07]mm2,P<0.001).Two patients in the double stent technique group underwent target vessel revascularization,there was no MACE in the other two groups(P=0.118). Conclusions:The"L-sandwich"technique is safe and feasible for the treatment of coronary bifurcation lesions.Compared with double-stent group,the SB ostium has a smaller LLAL at the time of review,and there is no significant difference in the MLA of each site,and the operation steps are significantly simplified.Use of the"L-sandwich"technique is associated with a better branching benefit compared with MV single-stent group.The"L-sandwich"technique could be used as a remedial procedure for severe entrapment in the setting of branching with DCB alone.

Objective:To establish UPLC fingerprint method and 2 contents determination methods of Buddleja officinalis; To provide a reference for improving the quality control standard and evaluation of Buddleja officinalis from different habitats.Methods:UPLC method was used to establish the fingerprints of 17 batches of Buddleja officinalis. The similarity evaluation, clustering analysis, principal component analysis and orthogonal partial least squares discriminant analysis were used to compare the quality differences of Buddleja officinalis from different habitats. The contents of acteoside and linarin in Buddleja officinalis were determined.Results:There were 12 common peaks in UPLC fingerprints of Buddleja officinalis, six of which were identified as echinacoside, acteoside, cynaroside, isoacteoside, linarin, and apigenin. The fingerprint similarity of 17 batches of Buddleja officinalis was more than 0.9; Buddleja officinalis from different habitats were classified into 2 groups. Five differential markers were determined by OPLS-DA analysis. The order of significance was acteoside > peak 3 > echinacoside > isoacteoside > linarin. Edgeworthia chrysantha was identified by the method of fingerprint as counterfeit.

Objective:To reconstruct the dose of nasopharyngeal carcinoma and verify the results of the whole-process radiotherapy plan based on log files and cone beam CT (CBCT).Methods:A total of 15 patients with nasopharyngeal carcinoma who received volumetric modulated arc therapy (VMAT) with Halcyon accelerator in the Cancer Center of Union Hospital, Tongji Medical College, Huazhong University of Science and Technology from February to September 2022 were retrospectively selected. Log files and CBCT for all fractionated radiotherapy were recorded. The errors of monitor unit (MU), gantry angle, and multi-leaf collimator (MLC) leaf position per control point were analyzed. The adaptive CT (aCT) were generated according to CBCT and planned CT (pCT) using a commercial software Velocity TM, and the similarities among aCT, pCT and CBCT were analyzed. The original plan was modified from the log files and imported into the treatment planning system to calculate the delivered dose on the corresponding fractionated aCT to reconstruct the fractionated dose. And all the reconstructed doses were mapped back to pCT to obtain the cumulative dose. Theγpass ratios with criteria of 2 mm/2% and 2 mm/3% and the dose differences between the planned dose and the cumulative dose in the planning target volume (PTV) and organs at risk (OAR) were compared. Results:The root mean square (RMS) and the 95th percentile of the errors of MU, gantry angle and MLC leaf position errors were within an acceptable range. The aCT generated by Velocity TM had the anatomical structure of CBCT and the resolution, contrast, noise characteristics of pCT, which could be directly used for dose calculation. Compared with the planned dose, the changes of V 70 Gy of nasopharyngeal primary tumor (PTV nx), V 68 Gy of cervical glands (PTV nd) and V 60 Gy of planning target volume (PTV1) were -0.88%±1.91%, -2.99%±2.99% and -0.63%±0.93%, respectively, and V 40 Gy of parotid gland was increased to 2.65%±2.63%. Cumulative dose showed different degrees of PTV dose decrease ( P<0.05) and parotid dose was increased ( P<0.05). The γ pass ratio (2 mm/3%) between the cumulative dose and planned dose was 97.3%±2.7% and >95.0% in 86.7% of patients. Conclusions:Based on the log files and CBCT, the whole-process dose reconstruction of nasopharyngeal carcinoma patients can be carried out. According to the results of dose reconstruction, the radiotherapy effect of the target area and OAR can be quantitatively evaluated. In the case of high dose coverage and conformity of the original plan, the reconstruction results show that the cumulative dose coverage of the target area is decreased, whereas that of the parotid gland is increased.

The main mechanism of TCM in improving gastric cancer includes regulating cell proliferation and apoptosis, reversing cell resistance, reducing the ability of invasion and metastasis and epithelial-mesenchymal transformation, regulating immune function, inhibiting neovascularization, regulating autophagy exosome, and ferroptosis.

Objective:To study the effects of gender on clinical outcomes of extremely low birth weight infants (ELBWI) and to analyze the risk factors of mortality.Methods:From January 2011 to December 2020, ELBWI (birth weight <1 000 g) admitted to the Neonatology Department of our hospital were retrospectively studied. The infants were assigned into the male group and the female group. Incidences of major complications, survival rate and mortality rate were compared between the two groups. The infants were also assigned into survival group and death group according to their clinical outcomes. Binary multivariate unconditional Logistic regression was used to analyze the risk factors of mortality in ELBWI.Results:A total of 637 ELBWI cases were included. 311 cases were in the male group with a survival rate of 57.9% (180/311) and 326 cases were in the female group with a survival rate of 57.4% (187/326). The incidences of neonatal respiratory distress syndrome (RDS), bronchopulmonary dysplasia (BPD), pulmonary hemorrhage and severe intraventricular hemorrhage (IVH) in the male group were significantly higher than the female group ( P<0.05). Significant increases of survival rate existed for both groups year by year ( P<0.01).No significant differences existed in survival rate, mortality rate of infants receiving proactive treatment and mortality rate of infants withdrawing treatment between the two groups ( P>0.05). Multivariate unconditional Logistic regression analysis showed that withdrawing treatment ( P<0.01) and pulmonary hemorrhage ( P<0.05) were associated with increased risks of mortality. Conclusions:Male ELBWI have higher risks of RDS, BPD and severe IVH than female ELBWI. Withdrawing treatment and pulmonary hemorrhage are common risk factors of mortality for both male and female ELBWI.
