ObjectiveTo assess the risk of vector-born infectious diseases by monitoring the major vectors in the relevant venues of the 19th Hangzhou Asian Games in Fuyang competition area, so as to provide references for the prevention and control of vector in similar large-scale events or activities in the future. MethodsFrom April to October 2023, monitoring and evaluation of rodent, mosquito, fly and cockroach density levels were carried out in various venues and reception hotels in Fuyang competition area (venues and hotels were the 1st circle area, and various environments and places in the surrounding 500 meters were the 2nd circle area). SPSS 25.0 software was used to analyze the data, and chi-square test or Fisher’s precision probability test were used to calculate the qualified rate and positive rate. Moreover, the path index, landing index and Bretrau index were analyzed by Kruskal-Wallis H test. ResultsThe control effect of vector density in the 1st circle was significantly better than that in the 2nd circle. Since September, the monitoring indices of the venues in the two circles had reached the national A-level and B-level standard, respectively. The positive rate of rodent traces generally showed a trend of first increasing and then decreasing, and the peak was shown to occur in July and August, with the highest rate of 5.38%. The qualified rate of rodent prevention facilities continued to rise, and facilities in the 1st and 2nd circles had reached national A-level and B-level standard respectively in late August. The landing index and path index of mosquitoes basically showed a changing trend from high to low, with the highest landing index of 4.56 individuals·person-time^-1 and the highest path index of 2.44 places·km^-1.The adult fly infestation rate remained at a low level, with the highest rate of 4.17%, and the minimum qualified rate of fly prevention facilities was 28.57%, which reached the national standard after July. The positive detection rates of adult flies and cockroach traces showed no significant pattern, with the highest rate of 7.00% and 8.33%, respectively. The detection rate of live ootheca was always at a low level. ConclusionThe relevant venues in the Fuyang competition area of the 19th Asian Games in Hangzhou meet national standards in terms of vector control indicators such as rodents, mosquitoes, flies, cockroaches and other vectors. By means of environmental improvement, facilities for preventing rodents and flies, and deepening biological and chemical prevention and control methods, it can be ensured that there will be no vector-borne diseases and infestation incidents during the event.

Objective:To study the value of urine-based multi-dimensional bioinformatics evaluation model (utLIFE model) in early diagnosis and postoperative monitoring of upper urinary tract urothelial carcinoma (UTUC).Methods:Morning urine samples of patients clinically diagnosed with UTUC without bladder cancer from Peking University First Hospital from August 2022 to October 2022 were collected. Urine samples were collected before and after surgery, and DNA was extracted for gene sequencing. The utLIFE model previously constructed by our center was used to calculate the score, based on 155 gene mutation sites and copy number variation, and the score ≥60 was defined as utLIFE positive. The sensitivity of utLIFE model in diagnosis of UTUC was analyzed with postoperative pathology as the gold standard. The utLIFE scores before and after operation were also compared.Results:A total of 53 patients were included in this study, all of whom were confirmed as UTUC by postoperative pathology. The median age of patients was 66 (59, 72) years. Twenty-four cases (45.3%) of UTUC tumors were located in the renal pelvis, 26 cases (49.1%) were located in the ureter, and 2 cases (5.7%)involved both ureter and renal pelvis. There were 27 patients (50.9%) at T 1stage and 26 patients (49.1%) at ≥T 2 stage. Preoperative utLIFE score of 53 patients was 79 (70, 84). The sensitivity of preoperative utLIFE diagnosis of UTUC was 96.2% (51/53). utLIFE showed similar high sensitivity in T 1 stage and ≥T 2 stage [100.0% (27/27) vs. 92.3% (24/26), P=0.236], in N 0 and ≥N 1 stage [ 95.0% (38/40) vs. 100.0% (5/5), P=1.000]. In addition, the sensitivity of preoperative utLIFE was higher than that of urine cytology [ 95.2% (20/21) vs. 23.8% (5/21). P<0.001], fluorescence in situ hybridization (FISH) [ 92.6% (25/27) vs. 55.5% (15/27), P=0.004] and ureteroscopy [ 86.7% (13/15) vs. 60.0% (9/15), P=1.000]. A total of 45 patients postoperative utLIFE samples were collected, and the postoperative utLIFE score was significantly lower than that of preoperative [ 36 (18, 61) vs. 79 (70, 84), P<0.001]. Conclusions:utLIFE, as a non-invasive urine DNA bioinformatics assessment model, is significantly superior to cytology and FISH in early detection and has high sensitivity in diagnosis of UTUC, and can reflect perioperative minimal residual disease levels.

Therefore, the application of ChatGPT in improving the capabilities of primary healthcare services required extensive discussion and analysis throughout society. A comprehensive evaluation of potential risks and the establishment of corresponding policies and regulations were necessary to ensure the prudent and responsible introduction and application of ChatGPT, ultimately achieving the goal of empowering primary healthcare services.

Objective:To explore the effect of diclofenac sodium suppository combined with tramadol sustained-release tablets on postoperative pain relief and recovery in patients with mixed hemorrhoids.Methods:Sixty patients with mixed hemorrhoids who underwent external dissection and internal ligation at the Shenzhen Traditional Chinese Medicine Proctology Hospital from September to October 2023 were selected and randomly divided into A group and AS group using a random number table method, with 30 patients in each group. The group A patients received oral tramadol sustained-release tablets 4 hours after surgery, while the group AS received diclofenac sodium suppositories for anal canal therapy in addition to the group A. Two groups were compared for postoperative pain [Visual Analog Scale (VAS)] and patient comfort [Numerical Rating Scale (NRS)], cumulative tramadol consumption, supplementary rescue pethidine needs, and adverse reactions at 4, 8, 24, and 48 hours.Resultsl:The VAS of the AS group were lower than those of the A group at 4, 8, 24, and 48 hours after surgery. The NRS scores of the group A patients at 4, 8, and 24 hours were significantly better than those of the group AS. The cumulative consumption of tramadol in the AS group at 4, 8, 24, and 48 hours after surgery was significantly lower than that in the A group; The demand rate for postoperative rescue of pethidine in the group A was significantly higher than that in the group AS. The incidence of nausea in the group A was significantly higher than that in the group AS.Conclusions:The combination of postoperative diclofenac sodium suppositories and oral tramadol sustained-release tablets for mixed hemorrhoid surgery has a significant improvement effect on pain. It can reduce the dosage of tramadol, reduce the need for rescue and supplementary analgesia, and have fewer adverse reactions.

Objective    To study the learning curve of minimal invasive coronary artery bypass grafting (MICS CABG) and the influence on the perioperative clinical effects by analyzing operation time. Methods    From March 2012 to November 2020, 212 patients underwent MICS CABG by the same surgeon. Among them, 59 patients (52 males and average age of 62.89±8.27 years) with single vessel bypass grafting were as a single-vessel group and 153 patients (138 males, average age of 59.80±9.22 years) with multi-vessel bypass grafting were as a multi-vessel group. Two sets of operation time-operation sequence scatter plots were made and learning curve was analyzed by cumulative summation (CUSUM) and regression method of operation time. The surgical data of each group before and after the inflection point of the learning curve were compared with the main clinical outcome events within 30 days after surgery. Results    There was no death, perioperative myocardial infarction and stroke in 212 MICS CABG patients and no transfer to cardiopulmonary bypass or redo thoracotomy. The learning curve conformed to the cubic fitting formula. In the single- vessel group, CUSUM (x operation number)=–1.93+93.45×x–2.33×x2+0.01×x3, P=0.000, R2=0.986, the tipping point was 27 patients. In the multi-vessel group, CUSUM (x)=y=2.87+1.15×x–1.29× x2+3.463×x3, P=0.000, R2=0.993, and the tipping point was 59 patients. The two sets of case data were compared before and after the learning curve and there was no statistical difference in main clinical outcomes within 30 days (mortality, acute myocardial infarction, stroke, perioperative blood transfusion rate), ventilator tube, and intensive care unit retention. Conclusion    The learning curve of MICS CABG conforms to the cubic formula, and the process transitions from single to multiple vessels bypass. To enter the mature stage of the learning phase, a certain number of patients need to be done. Reasonable surgical procedures and quality control measures can ensure the safety during the learning phase.

Objective:To investigate the histopathological morphology, immunophenotype, molecular pathological features, clinical prognosis and treatment of monomorphic epithelial intestinal T-cell lymphoma (MEITL).Methods:The clinicopathological data of 5 patients with MEITL in Sichuan Jinyu Medical Laboratory Center Co., Ltd from March 2019 to February 2021 were retrospectively analyzed, and literatures were reviewed. All cases were tested by using histopathology, immunohistochemistry, in situ hybridization of Epstein-Barr virus (EBV) and T-cell clonability assessment, and 1 case had second-generation sequencing (NGS) test. Clinical follow-up was performed in 2 patients.Results:All 5 MEITL cases were middle-aged and old men. The histopathology showed that intestinal wall was diffuse with tumor cells infiltrating, and the cells were obviously epitheliophilic. All the tumor cells CD3, CD8, CD56, GrB were positively expressed, and expressions of other T-cell markers were different, among which 1 case had CD30 positive and 1 case had CD20 positive. All 5 cases were negative for EBV by in situ hybridization. Monoclonal rearrangement of T-cell receptor gene was detected in all 5 cases. Mutations of BCOR, JAK3, STAT5B and ATM were detected in 1 case by using NGS. Among 2 cases followed-up, 1 patient relapsed 7 months after he had the initial onset and underwent the first operation, and then he had another operation. This patient finally died of extensive metastasis in the lung, liver and abdominal cavity as well as ascites 13 months later; another patient died 1 month after emergency surgery for perforation.Conclusions:MEITL is a rare primary T-cell lymphoma of the digestive tract. The oncogenic event in the pathogenesis of MEITL mainly involves mutations in the tumor suppressor gene SETD2 and mutations in one or more genes of the JAK/STAT pathway. Currently, there is no standard treatment for MEITL. Most treatment options include surgical resection and anthracycline-based chemotherapy.
