Objective To study the effects of partial axillary lymph node dissection (PALD) on prognosis and upper limb function in patients with breast cancer. Methods Ninety-eight breast cancer patients with stage Ⅰ and Ⅱ were randomly divided into two groups and different surgical procedures following modified mastectomy were performed: partial axillary lymph node (level Ⅰ and Ⅱ) dissection (PALD) group (n=48) and total axillary lymph node (levelⅠ, Ⅱ and Ⅲ) dissection (TALD) group (n=50). The longterm positive relapse rate and upper limb function between 2 groups were compared. Results During the follow-up of 5 to 10 years (average 4.5 years), there were 2 cases (4.2%) of local recurrence on chest wall and one case (2.1%) of recurrence in axillary lymph node and one case (2.1%) of recurrence in supraclavicular lymph node in PALD group, and 2 cases (4.0%) of local recurrence on chest wall and no axillary lymph node recurrence and one case (2.0%) of recurrence in supraclavicular lymph node happened in TALD group. There was no statistical difference between PALD group and TALD group (Pgt;0.05). The incidence of upper limb edema and dysfunction was 4.2% (2/48) in PALD group and 16.0%(8/50) in TALD group (P＜0.01). There was no significant statistical difference of 5year and 10year survival rate between PALD group and TALD group (89.6% vs. 88.0%， 79.2% vs. 78.0%，Pgt;0.05). Conclusion PALD may reduce upper limb dysfunction after operation in patients with stage Ⅰ and Ⅱ breast cancer, and does not increase prognostic risk.
ObjectiveTo compare the efficacy and safety of Huaier and Sorafenib in treatment of small hepatocellular carcinoma(HCC)following radical resection. MethodsEighty-two patients with small HCC accepted radical liver resection and then taken Huaier or Sorafenib were collected retrospectively. These patients were divided into Huaier group(51 cases)and Sorafenib group(31 cases)according to the different administration drugs after operation. The baseline characteristics, tumor characteristics, survival rate, tumor recurrence rate, and side effects were compared between two groups. Results①There were no significant differences on the baseline demographic characteristics, liver function, and tumor characteristics between two groups(P > 0.05).②The overall survival rate and tumor-free survival rate had no significant differences between the Huaier group and the Sorafenib group(P=0.737, P=0.699).③The rate of recurrence or metastasis had no significant difference between the Huaier group and Sorafenib group(37.3% versus 32.3%, P=0.648). The most common site of the recurrence or metastasis was the liver and the lung followed.④There were only 5 cases suffered side effects after taking Huaier and no case needed Huaier discontinuance. However, 11 cases suffered side effects after taking Sorafenib and 3 cases needed Sorafenib discontinuance, and the rate of the side effect in the Sorafenib group was much higher than that in the Huaier group(35.5% versus 9.8%, P=0.026). ConclusionFor the small HCC who accepted radical liver resection, Huaier seems to be an effective and safe drug.
ObjectiveThe risk factors of relapse in 133 epileptic children after withdrawal were analyzed retrospectively and provide reference for clinical withdrawal.MethodsFrom January 2017 to March 2019, 133 children with withdrawal epilepsy were selected as the study object. According to whether there was recurrence during the follow-up period, the children with epilepsy were divided into recurrence group (42 cases) and non recurrence group (91 cases). The gender, age of onset, history of trauma, frequency of seizure before treatment, EEG before drug reduction, imaging, type of medication, family history, time of reaching control, course of disease before treatment, comorbidity, multiple attack types, withdrawal speed and EEG before treatment were observed and compared between the two groups. ResultsThere were significant differences in EEG (χ2 =7.621), medication type (χ2=8.760), time to control (χ2=6.618), course before treatment (χ2=6.435), multiple seizure types (χ2=5.443) and epilepsy comorbidity (χ2=42.795) between the two groups (P < 0.05). The results of Logistic multiple regression analysis showed that the recurrence of epileptic children after drug reduction / withdrawal was correlated with abnormal EEG before drug reduction [OR=9.268, 95%CI (2.255, 38.092)], combined drug treatment [OR=3.205, 95%CI (1.159, 8.866)] and course of disease > 1 year before treatment [OR=5.363, 95%CI (1.781, 16.150)] (P < 0.05).ConclusionsIn order to reduce the possibility of recurrence of epileptic children, the treatment time of epileptic children with abnormal EEG, combined medication and long course before treatment should be prolonged properly.
Objective To study the related risk factors for recurrence of venous thromboembolism （VTE）. Methods The literatures about the related factors for recurrence of VTE were searched. The relationships between the factors and recurrence of VTE were determined by meta-analysis. Results A total of 12 literatures were included. The results of meta-analysis showed that factors such as males， age＜50 years old， malignant tumor， and antiphospholipid syndrome related with the recurrence of the first VTE after treatment， but there were no correlation between the recurrence of VTE， the type of first VTE， and causes of VTE. Conclusions The recurrence of VTE correlate with various factors. In order to avoid the recurrence of VTE， the patients with the risk factors for recurrence of VTE should be appropriate to extend the duration of anticoagulation
Objective To investigate the cl inical outcome of treating dorsal wrist gangl ion with an improved surgical strategy by excising the gangl ion completely along their stalk and repairing the dorsal carpal l igaments under brachial anesthesia. Methods From March 2005 to January 2007, 34 patients with dorsal wrist gangl ion were treated and studied retrospectively. There were 14 males and 20 females, aged 25-65 years (43 years on average). The left sides were involved in 22 cases and right sides in 12 cases. Thirteen cases of relapse received excision for 1 to 4 times under local anesthesia, with amean period of 17 months (14 days to 7 years) from excision to recurrence. Twenty-one patients were first attack cases with a mean period of 11 months (15 days to 8 years) from diagnosis to excision. The size of the gangl ion ranged from 1.5 cm × 1.2 cm to 4.5 cm × 4.0 cm. Now, each surgical process was performed under brachial anesthesia, and a pneumathode tourniquet was used. In 6 patients, the stalks of gangl ion did not invade the carpal l igaments, and gangl ion was removed completely without immobil ization after operation. In 28 patients, the stalks of gangl ion invaded the carpal l igaments, gangl ion was excised completely along its stalk to the dorsal carpal structure; the l igaments were sutured directly in 16 cases and were repaired with adjacent tissue such as the wall of sheathing canal of extensor tendon in 12 cases. The wrists were immobil ised for 3 weeks. Results Primary wound heal ing was achieved in all incisions. All patients were followed up for 26-36 months with an average of 31.5 months. Only 2 cases (5.9%) recurred. The range of motion of the wrist remained normal and the symptom of the dorsal wrist was rel ieved sl ightly. Patients’ satisfaction score ranged from 60 to 100, with an average of 83.8. Conclusion The gangl ion should be excised completely together with defect repair of dorsal carpal l igament under brachial anesthesia and the wrist immobil ised for 3 weeks, the recurrence rate will be reduced greatly.
Objective To assess the clinical efficacy of statins for preventing stroke recurrence. Methods We searched The Cochrane Library, PubMed, EMbase, CBM, CSJD, and CJFD for randomized controlled trials on the use of statin drugs to prevent stroke recurrence (up to May 10, 2008), and manually searched key Chinese magazines in the related fields. Two reviewers extracted data independently using a designed extraction form. The quality of included trials was evaluated according to the Cochrane handbook 4.12. RevMan 5.0 software was used for data analysis. Results Six randomized controlled trials involving 9,675 patients were identified. The results of meta-analysis showed that there was no statistical difference in stroke recurrence rate (RR=0.94, 95%CI 0.84 to 1.04, P=0.21) and fatal stroke occurrence (RR=0.77, 95%CI 0.48 to 1.25, P=0.30) between statins and placebo groups, but a significant difference was found between the two groups in transient ischemic attack occurrence (RR=0.80, 95%CI 0.69 to 0.92, P=0.002). Conclusion Current evidence indicates that statin drugs have no superiority to prevent stroke recurrence and fatal stroke occurrence, but can prevent transient ischemic attack.
Modified Goligher’s highly selective vagotomy (HSV) for 217 cases of duodenal ulcers is reported. In this series they were: duodenal ulcer (100 cases), combined gastric and duodenal ulcers (79 cases) and complicated perforating, bleeding or stenosed ulcers (38 cases). In the complicated duodenal ulcer, HSV was usually carried out with suturing bleeding point, perforated ulcer or with pyloroplasty. With a follow-up of 3~20 years, the recurrence rate werelt;2% and 85.7% of cases had excellent or good results as Visick classification. Considerations relevant to the HSV technic are deemed worthy of emphasis; complete resection of gastric branches of anterior and posterior vagal trunks and preservation of the first limb of the "Crow’s foot", extended dissection of the distal 5-7cm of the esophagus and division of the distal 8-10cm of the bundle of the gastroepiploic vessels in order to deprive the whole parietal cell mass of its vagal supply. In 4 patients, recurrence were easily controlled with remedies or operation for gastric retention by rational type. The authors suggest that the modified HSV plus mucusdeprived antrectomy be the rational surgical choice for duodenal ulcer.
ObjectiveTo investigate the clinical efficacy of carbon dioxide (CO2) laser ablation in the treatment of laryngeal papilloma and analyze the relevant factors for recurrence. MethodsWe retrospectively analyzed the clinical data of 102 patients with laryngeal papilloma treated between February 2003 and October 2010 in our department. They were divided into the juvenile group (n=70) and adult group (n=32). Patients in both groups underwent microsurgery with CO2 laser ablation to remove the lesions under general anesthesia. During the process, we observed patients'site of lesions, recurrence time, the incidence of postoperative vocal adhesions, and the occurrence of malignancy. ResultsAll patients were followed up for 1 to 8 years. Eleven cases of vocal cord adhesion occurred, and patients with the adhesion all had former joint lesions, which accounted for 27.5% of all the anterior commissure adhesion patients. Four cases of malignancy all occurred in adults with an adult malignancy rate of 12.5%. Recurrence occurred in 41 cases and 76 cases of times, including 5 times in 2 cases, 4 times in 4 cases, 3 times in 3 cases, twice in 9 cases, and once in 23 cases. The difference in times of recurrence was significant between the juvenile and the adult group (P<0.05). Significant difference was found between single lesion and multiple lesion recurrence in both groups (P<0.05). There was no significant difference between the two groups in terms of single lesion recurrence (P>0.05), while the difference in multiple lesion occurrence was significant (P<0.05). The first recurrence time was within 12 months after surgery in both groups, and recurrence mainly occurred within 6 months after surgery. Single lesion and multiple lesion recurrence mainly manifested as anterior commissure lesions (2/3, 66.7%) and subglottic lesions (5/6, 83.3%) respectively. ConclusionMicro-laryngoscopy CO2 laser laryngeal papilloma resection is safe, effective, and minimally invasive in the treatment of laryngeal papilloma, and is the preferred surgical method in clinic, but it still needs further improvement.
To accurately capture and effectively integrate the spatiotemporal features of electroencephalogram (EEG) signals for the purpose of improving the accuracy of EEG-based emotion recognition, this paper proposes a new method combining independent component analysis-recurrence plot with an improved EfficientNet version 2 (EfficientNetV2). First, independent component analysis is used to extract independent components containing spatial information from key channels of the EEG signals. These components are then converted into two-dimensional images using recurrence plot to better extract emotional features from the temporal information. Finally, the two-dimensional images are input into an improved EfficientNetV2, which incorporates a global attention mechanism and a triplet attention mechanism, and the emotion classification is output by the fully connected layer. To validate the effectiveness of the proposed method, this study conducts comparative experiments, channel selection experiments and ablation experiments based on the Shanghai Jiao Tong University Emotion Electroencephalogram Dataset (SEED). The results demonstrate that the average recognition accuracy of our method is 96.77%, which is significantly superior to existing methods, offering a novel perspective for research on EEG-based emotion recognition.
Epilepsy is one of the most common neurological diseases in children, about 2/3 can be seizure-free after anti-seizure medications (ASMs) treatment, but there are still some drug-resistant epilepsy (DRE) need surgical treatment, epilepsy surgery including excision surgery, dissociation surgery and palliative surgery, surgery can make 30%~40% DRE fully controlled. Clinicians usually choose to discontinue ASMs after seizure-free for 1 to 2 years after epilepsy surgery, but there has been controversy about whether to discontinue ASMs after surgery in children with epilepsy, how long to discontinue ASMs, the timing of ASMs withdrawal, and there is still a lack of unified guidelines. This article will comprehensively analyze and summarize the risk of recurrence after ASMs withdrawal in children with epilepsy.
