To address the current issues of data imbalance and scarcity in photoplethysmography (PPG) data for type 2 diabetes mellitus (T2DM) prediction, this study proposes an improved conditional Wasserstein generative adversarial network with gradient penalty (CWGAN-GP). The algorithm integrated gated recurrent unit (GRU) networks and self-attention mechanisms to construct a generator, aiming to produce high-quality PPG signals. Various data augmentation methods, including the improved CWGAN-GP, were employed to expand the PPG dataset, and multiple classifiers were applied for T2DM prediction analysis. Experimental results showed that the model trained on data generated by the improved CWGAN-GP achieved the optimal prediction performance. The highest accuracy reached 0.895 0, and compared with other data enhancement methods, this approach exhibited significant advantages in terms of precision and F1-score. The generated data notably enhances the accuracy and generalization ability of T2DM prediction models, providing a more reliable technical basis for non-invasive early T2DM screening based on PPG signals.

Objective:To compare the short- and long-term outcomes of robotic versus laparoscopic gastrectomy in patients with locally advanced gastric cancer after neoadjuvant chemotherapy.Methods:Data from 321 patients with locally advanced gastric cancer undergoing neoadjuvant chemotherapy followed by robotic ( n=109) and laparoscopic ( n=212) radical gastrectomy at our center between May 2017 and Sep 2022 was collected. After 1∶1 propensity score matching, 106 patients from each group were included in the final analysis to compare short-term clinical outcomes and long-term prognostic indicators. Results:The robotic group had a significantly lower overall complication rate (13.2% vs. 28.3%, χ2=6.453, P=0.007) and surgery-related complication rate (8.5% vs. 17.9%, χ2=3.333, P=0.043) than the laparoscopic group. The robotic group also retrieved more total lymph nodes (35.3±4.9 vs. 31.4±6.3, t=4.863, P<0.001) and supra-pancreatic lymph nodes (13.1±3.4 vs. 10.1±2.1, t=5.258, P<0.001). Additionally, the robotic group had a shorter operative time [(218±47) min vs. (267±71) min, t=-6.001, P<0.001], less intraoperative blood loss [(47±12) ml vs. (71±17) ml, t=-5.424, P<0.001], and faster postoperative recovery. The 3-year recurrence-free survival rate was significantly higher in the robotic group compared to the laparoscopic group (75.5% vs. 62.3%, P=0.017). Conclusion:Compared with laparoscopic gastrectomy, robotic gastrectomy allows for a more lymph nodes harvest, significantly reduces intraoperative blood loss and complication rates and significantly improves recurrence-free survival.

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 analyze the global epidemiology of renal cell carcinoma (RCC) in 2020. Methods: The incidence and mortality data of RCC in the cooperative database GLOBOCAN 2020 of International Agency for Research on Cancer of WHO and the human development index (HDI) published by the United Nations Development Programme in 2020 were collated. The crude incidence rate (CIR), age-standardized incidence rate (ASIR), crude mortality rate (CMR), age-standardized mortality rate (ASMR) and mortality/incidence ratio (M/I) of RCC were calculated. Kruskale-Wallis test was used to analyze the differences in ASIR or ASMR among HDI countries. Results: In 2020, the global ASIR of RCC was 4.6/100 000, of which 6.1/100 000 for males and 3.2/100 000 for females and ASIR was higher in very high and high HDI countries than that in medium and low HDI countries. With the rapid increase of age after the age of 20, the growth rate of ASIR in males was faster than that in females, and slowed down at the age of 70 to 75. The truncation incidence rate of 35-64 years old was 7.5/100 000 and the cumulative incidence risk of 0-74 years old was 0.52%. The global ASMR of RCC was 1.8/100 000, 2.5/100 000 for males and 1.2/100 000 for females. The ASMR of males in very high and high HDI countries (2.4/100 000-3.7/100 000) was about twice that of males (1.1/100 000-1.4/100 000) in medium and low HDI countries, while the ASMR of female (0.6/100 000-1.5/100 000) did not show significant difference. ASMR continued to increase rapidly with age after the age of 40, and the growth rate of males was faster than that of females. The truncation mortality rate of 35-64 years old was 2.1/100 000, and the cumulative mortality risk of 0-74 years old was 0.20%. M/I decreases with the increase of HDI, with M/I as 0.58 in China, which was higher than the global average of 0.39 and the United States' 0.17. Conclusion: The ASIR and ASMR of RCC presented significant regional and gender disparities globally, and the heaviest burden was in very high HDI countries.

The continuous development of high-throughput and single-cell sequencing technologies and the emergence of spatial transcriptome sequencing have allowed the continuous discovery of temporal and spatial molecular events in the progression of colorectal cancer (CRC) to better understand its mechanism of malignant progression. Genetic variations (mutation of APC and P53, etc.) and mismatch repair of DNA, posttranscriptional regulation, such as epigenetic alteration, and dynamic alteration of complex molecular networks have their own special molecules that play key roles. Drug resistance and metastasis in the late stage of CRC progression are closely related to these key molecular events. This article reviews the research progress and explores key molecular events in the malignant progression of CRC to provide scientific basis and ideas for elucidating the regulatory mechanism of CRC and evaluating its prognosis prediction and treatment.

Glaucoma is one of the most common optic neuropathies, featuring progressive retinal ganglion cell damage and visual field loss (Tham et al., 2014; Xu et al., 2020). Currently, the only effective treatment for this condition is the reduction of intraocular pressure (IOP) (Palmberg, 2001; Heijl et al., 2002). Canaloplasty is a proven bleb-independent surgery with good efficacy and safety profiles in primary open-angle glaucoma (POAG) (Gołaszewska et al., 2021). However, early transient postoperative IOP elevation has been reported in up to 30% of cases (Riva et al., 2019), similar to that commonly observed in other internal drainage glaucoma surgeries such as implantation using iStent (0%-21.0%), CyPass (10.8%), and Hydrus (4.8%-6.5%) (Lavia et al., 2017). This complication may be a predictor of poor reserve in the outflow system and is potentially associated with surgical failure. Nonetheless, the exact pathophysiology of glaucoma remains unknown, and studies clarifying the risk factors for postoperative IOP elevation have been scarce.
