Objective To explore the feasibility and safety of tension-free vaginal tape-obturator for female stress urinary incontinence under the daytime surgical mode based on the concept of enhanced recovery after surgery. Methods The clinical data of female patients with stress urinary incontinence at the First Affiliated Hospital of Kunming Medical University between June 2019 and June 2023 were retrospectively analyzed. According to the perioperative management mode of patients, they were divided into daytime surgery group and routine surgery group. The basic, intraoperative, and postoperative conditions of two groups of patients were compared. Results Finally, 183 patients were included, including 91 in the routine surgery group and 92 in the daytime surgery group. All patients successfully completed the surgery. There was no statistically significant difference in age, preoperative comorbidities, surgeon in chief, or operation duration between the two groups of patients (P>0.05). The preoperative waiting time after hospitalization [(0.00±0.00) vs. (2.42±0.58) d], hospitalization expenses [(13815.10±2906.01) vs. (18095.21±3586.67) yuan], total surgical expenses [(3961.36±707.35) vs. (4440.19±1016.31) yuan], anesthesia expenses [(718.53±61.06) vs. (755.30±74.65) yuan], western medicine expenses [(818.07±259.30) vs. (1282.14±460.75) yuan], total hospitalization duration [(1.11±0.31) vs. (5.77±1.30) d], and postoperative hospitalization duration [(1.11±0.31) vs. (3.35±1.42) d] in the daytime surgery group were lower than those in the routine surgery group (P<0.05). There was no significant difference between the two groups in postoperative complications (respiratory complications, fever, nausea and vomiting, vaginal bleeding, urinary retention, peritonitis), satisfaction, postoperative pain or self perception of symptom improvement (P>0.05). Conclusion The daytime surgery for female stress urinary incontinence based on the concept of enhanced recovery after surgery is safe and feasible, which can shorten hospitalization duration and reduce hospitalization costs.
In order to accurately evaluate the similarity of motions during daily rehabilitation training for stroke patients, this paper proposed a novel quantitative assessment method based on dynamic time warping (DTW) algorithm. Firstly, the raw accelerometer signals were preprocessed to eliminate the noise. Secondly, the similarity between the accelerometer signals and four standard task templates was calculated respectively, and then the motion was recognized based on the similarity measurements. Finally, the corresponding quantitative assessment model was used to compute the result. The clinical experimental results showed that there were significant differences in the shortest path distance (R value) of DTW between different tasks, and the classification accuracy could be up to 91% when the R value was selected as the classification feature. Additionally, with the process of rehabilitation, the R value decreased gradually, which means that the R value can be taken as the assessment index to evaluate the quality of designated tasks for stroke patients. It also indicated that the R value could be applied into the scene of automatic prescription generation and interactive gaming to determine whether it is needed to change the rehabilitation plan or adjust the game difficulty level, so as to implement the individualized rehabilitation services.
Platform daytime chemotherapy means that the hospital sets up a fixed area for daytime chemotherapy, and all patients with daytime chemotherapy are treated in the same area. The platform daytime chemotherapy center has the advantages of further optimizing the limited hospital resources, reducing the consumption of medical resources, and improving the efficiency of bed use and patient satisfaction. Its construction is the further sublimation of tumor treatment concept, harmonious relationship between doctors and patients, and humanistic care. This article shares the construction experience of the platform daytime chemotherapy center from the definition, orientation, operation mechanism, ward configuration, drug access, patient access and management mode, and puts forward suggestions that the promotion of the platform daytime chemotherapy center should be carried out from the aspects of policy support, hospital vigorously promoting and self-management breakthrough.
It has always been an important policy of the Chinese government to provide aid and assistance for the development of Tibet. With nearly one-eighth of China’s total land areas and about 0.002% of China’s total population, the Tibet Autonomous Region lags behind the domestic average level in medical education and is in bad need for medical professionals. The West China Center of Medical Sciences (WCCMS) of Sichuan University has managed to introduce US projects to set up the West China–Tibet Telemedical Education System to transmit medical courses in a real-time and interactive way. Based on this system, WCCMS has established a model for assisting the Tibet University Medical College through transmitting medical courses, training their medical faculty, sending WCCMS faculty to work in Tibet and admitting medical teachers and students from Tibet to study and be trained at West China Medical School and Hospital.
Objective To explore the differential diagnosis significance of 3.0T MRI united-sequences examination in the diagnosis of benign and malignant breast lesions. Methods A total of 67 breast lesions of 59 patients were collected prospectively, which be treated at the Sichuan Provincial People’s Hospital during July 2015 to January 2017. All patients were underwent bilateral breast 3.0T magnetic resonance plain scan, diffusion weighted imaging, and dynamic enhanced scan successively before surgical operation. Analysis of morphological features of the benign and malignant breast lesions, the time-signal intensity curve (TIC), the apparent diffusion coefficient (ADC), and the combination diagnosis of them were performed. Results Of all 59 patients, 67 lesions were confirmed by histopathology, including 18 benign lesions and 49 malignant lesions. The morphological features (including margin, shape, border, and evenness), the types of TIC of dynamic enhancement, and ADC value between the benign lesions and malignant lesions were statistically significant (P<0.05). The sensitivity and specificity of Fischer scoring system was 89.8% (44/49) and 61.1% (11/18) respectively. The sensitivity and specificity of TIC types was 83.7% (41/49) and 77.8% (14/18) respectively. The diagnostic threshold of ADC value was 1.012×10–3 mm2/s, with the sensitivity and specificity for the diagnosis was 91.8% (45/49) and 83.3% (15/18) respectively. The sensitivity and specificity of the combination of Fischer scoring system and TIC type for diagnosis between benign and malignant breast lesions was 95.9% (47/49) and 72.2% (13/18) respectively. The sensitivity and specificity of the combination of Fischer scoring system, TIC type, and ADC value for benign and malignant breast lesions was 98.0% (48/49) and 83.3% (15/18) respectively. Conclusion The combination of Fischer scoring system, TIC type, and diffusion-weighted imaging for the differential diagnosis between benign lesions and malignant lesions was more effective than single imaging method.
ObjectiveTo further evaluate the relation between usage of proton pump inhibitor (PPI) and the risk of pancreatic cancer. MethodThe observational studies were systematically searched in the databases of PubMed, Embase, Web of Science, Cochrane Library, ClinicalTrials.gov, CNKI, Wanfang, and VIP. The combined odds ratio (OR) and 95% confidence interval (CI) of pancreatic cancer risk were estimated by the corresponding effect model according to the heterogeneous results, and the subgroup analysis, meta-regression, and sensitivity analysis were performed. In addition, the relation between the defined daily dose (DDD) and usage time of PPI and the pancreatic cancer risk were studied by using restricted cubic spline. ResultsA total of 14 studies were included, including 1 601 430 subjects. The meta-analysis result showed that usage of PPI was positively correlated with the risk of pancreatic cancer [I2=98.9%, OR (95%CI)=1.60 (1.21, 2.11), P<0.001]. The subgroup analysis results showed that usage of PPI would increase the risk of pancreatic cancer in the subgroups of literature published before 2018 [OR (95%CI)=1.88 (1.05, 3.38), P=0.034], non-Asian regions [OR (95%CI)=1.37 (1.04, 1.82), P=0.028], case-control studies [OR (95%CI)=1.59 (1.16, 2.18), P=0.004], cohort studies [OR (95%CI)=1.65 (1.13, 2.39), P=0.009], and high-quality studies [OR (95%CI)=1.62 (1.19, 2.20), P=0.002]. The dose-response curve showed that there was a nonlinear relation between the usage of PPI and the risk of pancreatic cancer (χ2linear=2.27, P=0.132; Pnonlinear=0.039). When the usage of PPI was 800 DDD or less, usage of PPI would increase the risk of pancreatic cancer, but there was no statistical significance when the usage of PPI was more than 800 DDD. The time-effect curve showed that there was a linear relation between the usage time of PPI and the risk of pancreatic cancer (χ2linear=6.92, P=0.009), and the risk of pancreatic cancer would increase by 2.3% if the usage of PPI increased by one month [OR=1.02, 95%CI (1.01, 1.04), P=0.009]. The sensitivity analysis confirmed that the results were stable by gradually eliminating each study, the OR (95%CI) of the risk of pancreatic cancer was 1.37 (1.08, 1.74) to 1.66 (1.22, 2.27), and the publication bias was not found by Egger test (P=0.594).ConclusionsFrom the results of this meta-analysis, usage of PPI will increase the risk of pancreatic cancer, and the dosage of PPI and usage time of PPI may be related to the risk of pancreatic cancer. The clinical usage of PPI should be strictly controlled, and the dosage and usage time should also be carefully considered.
Surface electromyography (sEMG) has been widely used in the study of clinical medicine, rehabilitation medicine, sports, etc., and its endpoints should be detected accurately before analyzing. However, endpoint detection is vulnerable to electrocardiogram (ECG) interference when the sEMG recorders are placed near the heart. In this paper, an endpoint-detection algorithm which is insensitive to ECG interference is proposed. In the algorithm, endpoints of sEMG are detected based on the short-time energy and short-time zero-crossing rates of sEMG. The thresholds of short-time energy and short-time zero-crossing rate are set according to the statistical difference of short-time zero-crossing rate between sEMG and ECG, and the statistical difference of short-time energy between sEMG and the background noise. Experiment results on the sEMG of rectus abdominis muscle demonstrate that the algorithm detects the endpoints of the sEMG with a high accuracy rate of 95.6%.
Objective To investigate the relationship between delayed diagnosis time (time from symptom onset to diagnosis) in patients with chronic obstructive pulmonary disease (COPD) and the burden of type 2 inflammation (defined as the persistent inflammatory status assessed by blood EOS counts, EOS%, and Fractional exhaled nitric oxide(FeNO) among other biomarkers).MethodsThis study was a single-center, observational study that included patients with COPD first diagnosis at the respiratory outpatient department of our hospital from June 2023 to December 2024. Asthma-COPD overlap (ACO) were identified according to the 2017 Spanish COPD guidelines. Clinical data were collected, including gender, age, delayed diagnosis time, acute exacerbations in the past year, pulmonary function tests, exhaled nitric oxide (FeNO), and type 2 inflammatory markers such as blood eosinophil counts (EOS). The correlation between the delayed diagnosis time and type 2 inflammation burden, as well as its influencing factors, were analyzed. Results A total of 195 patients were included, with 98 cases of COPD and 97 cases of ACO. The mean delayed diagnosis time was 18.0 (2.8, 37.5) months for the overall patients, 24.0 (1.0, 60.0) months for COPD, and 16.5 (3.0, 36.0) months for ACO, with no significant difference between the COPD and ACO groups (P>0.05). The median blood EOS counts, EOS%, andFeNO levels were 180 cells/μL, 1.9%, and 18 ppb in the COPD group, respectively, compared to 350 cells/μL, 4.7%, and 28 ppb in the ACO group, indicating higher type 2 inflammation levels in the ACO group (all P<0.001). A significant correlations were found between the disease course and the blood EOS counts and EOS% of the patients (respectively r=0.159, 0.152, all P<0.05).FeNO levels showed no significant correlation with delayed diagnosis time of COPD (P>0.05). Patients with a history of asthma and acute exacerbations in the past year had longer delayed diagnosis time and higher peripheral blood eosinophil counts (all P<0.05). Binary logistic regression analysis revealed that BMI and delayed diagnosis time were independent influencing factors for blood EOS counts (all P<0.05). ConclusionDelayed diagnosis of COPD was associated with aggravated type 2 inflammatory burden. Clinical practice should emphasize early recognition of COPD symptoms and implement prompt therapeutic interventions.

ObjectiveTo explore the related factors of postoperative survival of patient with gastric cancer, so as to provide the corresponding evidence support for the prognosis evaluation.MethodsThe clinicopathologic data of patients with gastric cancer who underwent surgical treatment in the Fourth Affiliated Hospital of Baotou Medical College and the Fourth Hospital of Baotou City from January 2006 to December 2009 were retrospectively collected. The influences of clinicopathologic data (gender, age, tumor size, tumor location, lymph node metastasis, tumor thrombus, tumor differentiation, TNM stage, operation mode, and postoperative chemotherapy) on postoperative survival of patients with gastric cancer were analyzed. Univariate analysis was used to analyze the influencing factors of postoperative survival in the patients with gastric cancer and Cox proportional hazards regression was used to analyze the independent risk factors.ResultsA total of 80 patients with gastric cancer were included in this study. Up to December 31, 2014, the median survival time at 50% cumulative survival rate was 95 months. Univariate analysis showed that the survival of patients with gastric cancer was related to tumor size, lymph node metastasis, tumor differentiation, and TNM stage (P<0.05). Further multivariate analysis showed that later TNM stage was an independent risk factor for affecting postoperative survival of patients with gastric cancer (P<0.05).ConclusionPostoperative survival of patients with gastric cancer is related to tumor size, lymph node metastasis, tumor differentiation, and TNM stage; And later TNM stage is an independent risk factor for affecting survival of patients with gastric cancer.
