Objective To investigate the population density and seasonal fluctuations of Aedes albopictus in Guangzhou City, Guangdong Province, from 2021 to 2023, so as to provide insights into A. albopictus control and management of dengue fever. Methods The surveillance of A. albopictus density was performed in all surveillance sites assigned across all streets (townships) in Guangzhou City during the period from January to December from 2021 to 2023. The surveillance frequency was twice every half month from May to September, and once every month for the rest of a year. In each surveillance period, A. albopictus mosquito larvae were captured from indoor and outdoor small water containers in residential areas, parks, medical facilities, schools, other government sectors and social organizations, construction sites, special industries and others for mosquito species identification. Adult mosquitoes were captured using electric mosquito suction apparatus for species identification and gender classification. Adult mosquitoes and mosquito eggs were collected with mosquito and egg traps at the breeding and dwelling places of Aedes mosquitoes for identification. The mosquito oviposition index (MOI), Breteau index (BI), adult mosquito density index (ADI) and standard space index (SSI) were calculated. The A. albopictus density was classified into grades 0, 1, 2 and 3 in each surveillance site, with Grade 0 density defined eligible, and the eligible rate of A. albopictus density was calculated at all surveillance sites each year from 2021 to 2023. In addition, the changing trends in MOI, SSI, BI and ADI of A. albopictus were analyzed in Guangzhou City from 2021 to 2023. Results The eligible rates of A. albopictus density were 61.69%, 68.75% and 55.15% in surveillance sites of Guangzhou City from 2021 to 2023 (χ² = 297.712, P < 0.001), and appeared a tendency towards a reduction followed by a rise each year, which gradually reduced since January, maintained at a low level during the period between May and October, and gradually increased from November to December. The MOI, SSI, BI and ADI of A. albopictus all appeared a tendency towards a rise followed by a reduction in Guangzhou City during the period between January and December from 2021 to 2023. The BI of A. albopictus peaked in the first half of June in 2021 (4.03), the first half of July in 2022 (3.89) and the last half of August in 2023 (5.02), and the SSI of A. albopictus peaked in the last half of June in 2021 (0.93), the last half of May in 2022 (0.59), and the last half of June (0.94) and the first half of September in 2023 (1.12). In addition, the MOI of A. albopictus peaked in the first half of May in 2021 (8.64), the first half of June in 2022 (8.96), and the last half of May (10.21) and the last half of June in 2023 (10.89), and the ADI of A. albopictus peaked in the first half of June in 2021 (3.41), the last half of June in 2022 (4.06), and the first half of July in 2023 (3.61). Conclusions The density of A. albopictus is high in Guangzhou City during the period from May to October, and the risk of local outbreak caused by imported dengue fever is high. Persistent intensified surveillance of the density and seasonal fluctuation of A. albopictus is recommended and timely mosquito prevention and control is required according to the fluctuation in the A. albopictus density.

Robot-assisted surgery with its advantages such as three-dimensional high-definition vision, dexterous robotic arms, and tremor filtration, is increasingly being applied to complex radical gastrectomy. However, the role of the surgical assistant remains crucial during the procedure. The assistant is responsible for tasks outside the console, including adjusting robotic arms, changing instruments, exposing the surgical field, and addressing unexpected situations. The technical proficiency of the assistant and their collaboration efficiency with the primary surgeon directly impact the smoothness of surgery and patients' outcomes. With the expansion of robot-assisted surgical indications, the establishment of a standardized training system and the optimization of team collaboration models have become urgent challenges to address. This article draws on the author's practical experience as an assistant in robot-assisted gastric cancer surgeries, conducting an in-depth analysis of the responsibilities and operational skills of surgical assistants in robot-assisted procedures. The aim is to develop a relatively comprehensive set of operational guidelines for surgical assistants in robot-assisted radical gastrectomy, providing valuable references for enhancing the overall efficiency of surgical teams and improving surgical outcomes.

Objective To observe the value of traditional pelvic floor ultrasound parameters combined with middle urethral sphincter elasticity parameters for diagnosing female stress urinary incontinence(SUI).Methods Fifty two female SUI patients(SUI group)and 45 healthy women(control group)were prospectively enrolled.Traditional pelvic floor ultrasound parameters and middle urethral sphincter elasticity parameters were compared between groups,and logistic regression analysis was performed,the efficacy of each parameter alone and their combination for diagnosing SUI was analyzed.Results Significant differences of bladder neck descent(BND),urethral rotation angle(URA),posterior urethrovesical angle(PUA),shear modulus of the middle urethral anterior wall sphincter at rest state(Q1),shear modulus of the middle urethral anterior wall sphincter under maximum Valsalva maneuver(Q2),and shear modulus of the middle urethral posterior wall sphincter at resting-state(H1)were found between groups(all P＜0.05).BND,PUA,Q1 and Q2 were all influencing factors of female SUI(all P＜0.05),with the area under the curve(AUC)for diagnosing SUI of 0.721,0.718,0.659 and 0.288,respectively.Then traditional ultrasound model,elasticity ultrasound model and combined model were constructed based on traditional pelvic floor ultrasound parameters(BND,PUA),middle urethral sphincter elasticity parameters(Q1,Q2)and their combination,respectively,with AUC for diagnosing SUI of 0.837,0.754 and 0.908,respectively.The AUC of combined model was higher than that of traditional ultrasound model,elasticity ultrasound model and each ultrasound parameter alone(all P＜0.05).Conclusion Traditional pelvic floor ultrasound parameters combined with middle urethral sphincter elasticity parameters had high value for diagnosing female SUI.

The control group was treated with methylphenidate hydrochloride tablets and tiapride hydrochloride, and the observation group was treated with Jingling oral liquid on the basis of the control group. Both groups were treated continuously for 16 weeks. The clinical efficacy and number of seizures of the two groups were compared, the clinical symptoms of the two groups were assessed by the Conner Parent Symptom Questionnaire (PSQ) and the Swanson Nolan and Pelham Version Ⅳ(SNAP-Ⅳ), and the intelligence level of the two groups was assessed by the Wechsler Intelligence Scale. The serum levels of DAT, IL-6, 8-iso-PGF-(2α), neurotrophic factors before and after treatment and the occurrence of adverse reactions were compared between the two groups.Results:After treatment, the effective rate in the observation group was higher than that in the control group: 93.33% (56/60) vs. 80.00% (48/60), there was statistical difference ( χ2 = 4.62, P<0.05). After treatment, the number of seizures in the observation group was less than that in the control group at 3, 4 to 6, 7 to 12 months: (10.78 ± 1.45)times vs.(14.18 ± 1.56) times, (4.86 ± 0.53) times vs.(8.63 ± 0.89) times, (2.64 ± 0.32) times vs. (4.11 ± 0.45) times, there were statistical differences ( P<0.05). After treatment, the scores of PSQ and SNAP-Ⅳ in the observation group were lower than those in the control group: (13.67 ± 1.48)scores vs. (15.18 ± 1.59) scores, (22.12 ± 2.35) scores vs. (25.37 ± 2.68)scores; while the scores of Wechsler intelligence scale was higher than that in the control group: (93.65 ± 9.77)scores vs.(89.42 ± 8.89) scores, there were statistical differences ( P<0.05). After treatment, the serum levels of DAT, IL-6 and 8-iso-PGF-(2α) in the observation group were lower than those in the control group: (0.46 ± 0.05) μg/L vs. (0.52 ± 0.06) μg/L, (8.26 ± 0.89) ng/L vs. (8.74 ± 0.92) ng/L, (60.38 ± 6.46) ng/L vs.(79.25 ± 8.14) ng/L, there were statistical differences ( P<0.05). After treatment, the serum levels of S100βprotein, brain-derived nerve growth factor and prolactin in the observation group were higher than those in the control group: (41.55 ± 4.28) ng/L vs. (37.26 ± 3.87) ng/L, (498.33 ± 54.26) ng/L vs.(442.15 ± 45.78) ng/L, (10.18 ± 1.14) μg/L vs. (9.69 ± 0.97) μg/L, there were statistical differences ( P<0.05).There was no significant difference in gelatinous-derived nerve growth factor level between the two groups after treatment ( P>0.05). There was no significant difference in the incidence of adverse reactions between the two groups ( P>0.05). Conclusions:Jingling oral liquid combined with methylphenidate hydrochloride and thiopride hydrochloride in the treatment of ADHD co-induced by epilepsy has good efficacy, and can significantly improve their clinical symptoms, regulate the levels of serum DAT, IL-6, 8-iso-PGF-(2α). It is safe and reliable.

Objective To observe the value of middle urethral motion and sphincter elasticity for diagnosing female stress urinary incontinence(SUI).Methods Totally 97 female patients,including 52 with SUI(SUI group)and 45 without SUI(control group)were prospectively enrolled.Pelvic floor ultrasound was performed under resting state and the maximum Valsalva maneuver,respectively,and bladder neck mobility(BND),upper-lower mobility of middle urethra(UMupper-lower),anterior-posterior mobility of middle urethra(UM anterior-posterior),elasticity parameter of the anterior wall of middle urethral sphincter(ΔEanterior wall),as well as elasticity parameter of the posterior wall of middle urethral sphincter(ΔEposterior wall)were measured.Patients'general data and the above ultrasound parameters were compared between groups,and the efficacy of them for diagnosing SUI was analyzed.Results Significant differences of BND,UM upper-lower,ΔEanterior wall and ΔEposterior wall,of also the proportion of lateral episiotomy history were found between groups(all P＜0.05).Among them,UMupper-lower,ΔEanterior wall and ΔEposterior wall were all correlated with female SUI(rs=0.231,-0.533,-0.428,all P＜0.05).The area under the curve(AUC)of UMupper-lower,ΔEanterior wall,ΔEposterior wall and their combination for diagnosing SUI was 0.634,0.820,0.748 and 0.867,respectively.The AUC of the combination was significantly higher than that of each parameter alone(all P＜0.001).Conclusion The combination of middle urethral motion and sphincter elasticity was helpful for diagnosing female SUI.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.
