BACKGROUND: Lung cancer is the leading malignancy in China in terms of both incidence and mortality. With increased health awareness and the widespread use of low-dose computed tomography (CT), early diagnosis rates have been steadily improving. Surgical intervention remains the primary treatment option for early-stage lung cancer, and video-assisted thoracoscopic surgery (VATS) has become a common approach due to its minimal invasiveness and rapid recovery. However, post-discharge recovery remains incomplete, underscoring the importance of postoperative care. Traditional follow-up methods, lack standardization, consume significant medical resources, and increase the burden of the patients. Artificial intelligence (AI)-driven disease management platforms offer a novel solution to optimize postoperative follow-up. This study followed 463 lung cancer surgery patients using an AI-based platform, aiming to identify common postoperative issues, propose solutions, improve quality of life, reduce recurrence-related costs, and promote AI integration in healthcare. METHODS: Using the AI disease management platform, this study integrated educational videos, collaboration between healthcare teams and AI assistants, daily health logs, health assessment forms, and personalized interventions to monitor postoperative recovery. The postoperative rehabilitation status of the patients was assessed by the Leicester Cough Questionnaire (LCQ-MC). Two independent t-test and one-way ANOVA were used to analyze the causes of postoperative cough in lung cancer. RESULTS: Most issues occurred within 7 d post-discharge, significantly declined on 14 d post-discharge. Factors such as gender, smoking history, and surgical approaches were found to influence cough recovery. The incidence of cough on 7 d post-discharge in females was higher than that in males (P<0.01), while the incidence of cough on 14 d post-discharge in elderly patients was lower than that in young patients (P=0.03). The AI-based platform effectively addressed cough, pain, and sleep disturbances through phased interventions. CONCLUSIONS The AI-based platform significantly enhanced postoperative management efficiency and the self-care capabilities of the patients, particularly in phased cough management. Future integration with wearable devices could enable more precise and personalized postoperative care, further advancing the application of AI technology across multidisciplinary healthcare domains.

Percutaneous nephrolithotomy(PCNL)is important in the treatment of upper urinary tract stones,and tubeless day-time surgery is a promising approach.It can improve the patients'hospitalization experience and shorten hospitalization time,but it also faces risks such as difficulty in managing residual stones after surgery,urinary extravasation caused by poor ureteral drainage,and so on.Currently,there are insufficient guiding principles in this regard.Based on our experience and relevant literature,this paper will discuss the technical points of day-time tubeless PCNL and explore its feasibility.

A lightweight residual attention enhanced Unet(LRAE-Unet)is designed for the fully automatic brain tumor segmentation.LRAE-Unet uses lightweight residual module to solve the problems of gradient disappearance and network degradation when the network layers increases,lightweight self-attention module to suppress the irrelevant areas and highlight the significant features of specific local areas,and enhanced average pooling module with a larger field of perception to reduce the space of feature map,save computing resources and avoid over-fitting.The experiment on BraTS 2019 dataset shows that the proposed method has a Dice similarity coefficient of 91.24%,88.64%and 88.32%in the segmentations of the whole tumor,tumor core and enhanced tumor,which proves its feasibility and effectiveness for brain tumor segmentation.

Autologous ozonized blood transfusion(AOBT) is a therapy of re-transfusion of 100-200 mL of autologous blood after shaking and agitation with appropriate amount of oxygen-ozone in vitro. The oxidation of blood through the strong oxidation of ozone can enhance the non-specific immune response of the body, regulate the internal environment and promote health. This therapy has been increasingly applied in clinical practice, while no unified standard for the operation process in terms of ozone concentration, treatment frequency and treatment course had been established. This operation process of AOBT is primarily explored in order to standardize the operation process and ensure its safety and efficacy.

Objective:To compare the efficacy and safety of percutaneous nephrolithotomy (PCNL) with negative pressure suction sheath and PCNL with traditional expanded sheath in the treatment of infectious renal calculus.Methods:From May 2019 to June 2022 in our department, 35 patients with infectious renal calculus who received PCNL with negative pressure suction sheath (negative pressure sheath group, NPS group) and another 35 patients with infectious renal calculus who received PCNL with traditional expanded sheath (control group) were determined in our research. Propensity score matching (PSM) was conducted. Preoperative clinical data of the 2 groups was similar and there were no statistical differences between the 2 groups in the age [(45.5±6.8)vs. (44.9±7.3) years old, P=0.723], gender (man/woman 19/16 cases vs. 21/14 cases, P=0.629), body mass index(BMI) [(24.2±4.2)kg/m 2vs. (24.5±3.9)kg/m 2, P=0.758], American Society of Anesthesiologists risk score(ASA) (grade 1/grade 2: 30/5 cases vs. 29/6 cases, P=0.743), sides of calculus (left/right: 18/17 cases vs. left 17/18 cases, P=0.811), Guy’s stone score (grade Ⅰ/Ⅱ/Ⅲ: 3/25/7 cases vs. 1/29/5 cases, P=0.443), CT value of calculus [(629.2±98.8)HU vs. (608.5±105.1)HU, P=0.399], urinary leucocyte (-/+ /+ + : 29/5/1 cases vs. 28/5/2 cases, P=0.839), hypertension(3 cases vs. 5 cases, P=0.707), diabetes(2 cases vs. 2 cases, P=1.000). The ureteral catheter on the affected side was indwelled in the lithotomy position, and ultrasound guided positioning puncture was performed on the affected renal side of the posterior axillary line in the prone position. The puncture channel was established and then expanded to F20 successively, and the lithotriptic sheath was placed to establish the lithotriptic channel. Compared with the traditional expanded sheath, the negative pressure suction sheath was different in that the collateral suction channel was added on the main gravel channel and connected with continuous negative pressure suction. The negative pressure was 40 kPa. All patients were treated with pneumatic ballistic lithotripsy combined with holmium laser. KUB was performed within 1 week after surgery. We defined stone removal as either no residual stones or clinically insignificant residual stones (≤4 mm) which did not cause urinary obstruction. The intraoperative duration of operation and postoperative clinical parameters [white blood cell(WBC), procalcitonin(PCT), C-reactive protein(CRP), hemoglobin(Hb), stone clearance rate] and incidence of perioperative complications were compared between the 2 groups. Results:The operation time of NPS group was lower than that in control group [(35.6±19.5)min vs. (45.4±20.2)min, P<0.05]. The proportion of patients with increased WBC, PCT and CRP in blood after operation in NPS group was lower than that in control group, and there were (WBC: 25.7% vs. 54.3%, P<0.05), (PCT: 42.9% vs.68.6%, P<0.05) and (CRP: 62.9% vs.85.7%, P<0.05) respectively. There was no significant difference in the proportion of patients with decreased Hb postoperatively between the 2 groups (2.9% vs. 8.6%, P=0.607). There was no significant difference in calculus clearance rate postoperatively between the 2 groups (97.1% vs. 94.3%, P=1.000). Postoperative calculus component analysis of the 2 groups suggested that all patients had infected calculus dominated by ammonium magnesium phosphate and phosphate apatite. The incidence of perioperative complications in NPS group was lower than that in control group (22.9% vs. 51.4%, P<0.05). The proportion of patients with fever (body temperature>37.5℃) postoperatively in NPS group was lower than that in control group (14.3% vs. 37.1%, P<0.05). There were 2 and 3 patients respectively required upgraded antibiotic therapy after operation in the 2 groups ( P=1.000). There was one patient respectively with urinary tract obstruction and renal colic due to blood clots postoperatively in each group ( P=1.000). There was one patient with urinary sepsis in control group after operation ( P=0.476). Conclusions:Compared with PCNL with traditional expanded sheath, PCNL with negative pressure suction sheath can save operation time for infectious renal calculus, and reduce the incidence of postoperative infection and perioperative complications. Therefore, the safety of negative pressure suction sheath is higher. However, there is no difference in stone clearance rate between them.

OBJECTIVETo understand the prevalence of high risk behaviors and influencing factors among HIV infected persons aged ≥50 years.

METHODSFace to face questionnaire interview was conducted among the HIV infected persons selected in Jianshui, Gejiu and Mengzi counties in Yunnan province through random sampling in June 2015. The sample size was 450.

RESULTSAmong the HIV infected persons surveyed, 41.2% (122/296) had sexual behaviors with their spouses during past year, and the consistent condom use rate was 66.4% (81/122). Among the HIV infected males, 8.9% (28/313) had commercial sexual behaviors during past year, and the consistent condom use rate was 17.9% (5/28). Among the HIV infected females, 0.7% were still engaged in commercial sex service during past year. Among the 450 HIV infected persons, 32 (7.1%) reported having casual sex behaviors during past years, and the consistent condom use rate was 18.7% (6/32). The rate of commercial sexual behavior in urban residents (13.4%, 19/115) was higher than that in rural residents (4.5%, 9/198), the difference was statistically significant (χ(2)=11.715, P=0.001). The risk factors for commercial sex behaviors included lack of family and social support, aged 50-59 years, living in urban area, higher income and being male. The risk factors for using no condom included living in rural area, lower education level, lack of family and social support and higher income.

CONCLUSIONSRisk sex behaviors are still prevalent in HIV infected people aged >50 years, which exacerbated HIV transmission. Further efforts should be focused on the education about AIDS prevention and control and promoting protected sexual behaviors. Additional effort should be done to improve the family and social support for HIV infected people aged >50 years. Moreover, comprehensive intervention for low-paid female sex workers also needs to be strengthened.

Long non-coding RNA (lncRNA) is a class of RNA molecules, transcripted by RNA polymeraseⅡ, which consists of more than 200 nucleotides and protein-coding function. Many studies have indicated that lncRNA plays an important role in epigenetics, transcription and post-translational processing. The abnormal expression of lncRNA significantly correlates with occurence,development, and metastasis of renal cell carcinoma (RCC) and prognosis of the patients with RCC. This paper summarizes the advances in the research on lncRNA in RCC to reveal the mechanisms of the disease at the molecular level, in order to provide new methods of prevention, diagnosis, treatment and prognostic assessment of RCC.

OBJECTIVETo analyze the characteristics of risky behaviors among different age groups of HIV positive female sex workers, and to explore the strengthening of their management.

METHODSFrom January to June 2014, 22 814 female sex workers were investigated and tested HIV in 117 sentinel surveillance sites in Yunnan Province, and 181 were confirmed to be HIV antibody positive, who accepted questionnaire surveys. According to the age, the participants were divided into the < 35 years old age group and ≥ 35 years old age group. The demographic characteristics, knowledge about HIV/AIDS and related risk behaviors characteristics of the two groups were obtained via questionnaire surveys among 181 HIV positive female sex workers, and in-depth qualitative interviews were conducted from among 12 HIV positive sex workers.

RESULTSHIV antibody positive rate was 0.8% (181), the age of the 181 subjects were (35.83 ± 9.17) years old, 76 cases (42.0%) were < 35 years old, and 105 cases (58.0%) were ≥ 35 years old. The differences of marital status, workplace class, the last work site among two groups were statistically significant (χ(2) = 20.80, 28.32, 7.83; P < 0.001, P < 0.001, P = 0.020, respectively). Among 181 HIV, the proportion of AIDS awareness was 95.6% (173); the proportion of drug use among ≥ 35 years old age group was 51.4% (54), which was higher than that in < 35 years old age group (34.2%, 26/76) (χ(2) = 5.30, P = 0.021). 96.7% (175) received condom promotion or HIV counseling and testing in the past year. The proportion of continuing to engage in sexual services over 5 years after HIV infection was 48.5% (51/105) and the proportion of receiving antiretroviral treatment was 69.5% (73/105) in ≥ 35 years old age group, which were higher than those in the < 35 age group (30.2% (23/76), 52.6% (40/76); χ(2) = 12.26, 5.36; P = 0.002, 0.021, respectively). In-depth interviews among 12 HIV positive female sex workers found that regular clients, not consistent use of condoms were the main cause of no condom use. Economic and livelihood factors are important reasons for continuing to engage in sexual services among HIV positive sex workers.

CONCLUSIONHIV positive sex workers still have high risk behaviors including continuing to engage in commercial sexual service and no condom use after knowing their HIV infection status, and the proportion of using drugs in the ≥ 35 years old group was higher than that in < 35 years old group.

OBJECTIVETo understand the high risk behaviors of female sex workers (FSWs) in Yunnan province in 2013.

METHODSA cross-sectional investigation was conducted during April to June, 2013 in Yunnan province, census was used to the investigation where the number of FSWs was close to 200, while probability sampling was used where the number of FSWs was obviously over 200. A total of 25 574 cases were investigated, and data on demography and risk behaviors were obtained by questionnaires one by one.

RESULTSA total of 25 574 cases were investigated, AIDS awareness among FSWs in high-level places, middle-level places and low-level place were 98.8% (92/7 401), 98.6% (150/10 995), and 96.0% (281/6 655). FSWs from low-level place had a lower rate than those from the other two types of places (P < 0.01). The rate of condom use each time when having sex with clients within the recent one month among FESs from high-level places, middle-level places and low-level place were 93.4% (6 307/6 755), 93.8% (10 109/10 782) and 90.4% (6 053/6 697), and the FSWs working in low-level place had a lower rate than those from the other two types of places(P < 0.01). Multi-factor logistic regression analysis showed that the following had a lower rate of condom use: the FSWs working in low-level place (OR = 1.56, 95% CI:1.36-1.79; OR = 1.36, 1.16-1.59), over 30 years old (OR = 0.77, 95%CI:0.69-0.85), Yunnan citizen (OR = 0.88, 95% CI:0.77-1.00), minority (OR = 1.32, 95% CI:1.16-1.50), under senior high school (OR = 0.61, 95%CI:0.49-0.75), married (OR = 0.81, 95% CI:0.71-0.92), living together (OR = 0.70, 95% CI:0.51-0.96), divorced or lost spouses (OR = 0.81, 95% CI:0.65-1.02), worked less than 6 months in local areas (OR = 1.74, 95% CI:1.34-2.27), drug users (OR = 1.65, 95% CI:1.11-2.46), had not accepted HIV interventions (OR = 2.91, 95% CI:2.36-3.58), had no knowledge about AIDS (OR = 4.50, 95% CI:3.48-5.82). The main reasons for not using condoms were the clients' unwilling to use, which accounted for 47.62% (270/567). The total rate of drug use was 1.0% (264/25 567) and the FSWs working in middle-level places had the highest rate of injecting drugs, which accounted for 0.6% (70/11 141). The FSWs working in low-level places had a higher rate than those who worked in high-level places and middle-level places in venereal diseases, which accounted for 1.2% (85/6 934) (P < 0.01). The rate of receiving effective interventions was 96.7% (24 717/25 574), the rate of accepting treatment and clean needles among drug users was 21.6% (57/264).

CONCLUSIONHigh risk behaviors were serious among the FSWs who worked in low-level places, especially among the olders, the minorities, people who had lower educational level, the new-comer and drug users, which indicated that more attention needs to be paid among these populations.
