Venous system diseases mainly include varicose veins and venous malformations of lower limbs and the genital system. Most of them are chronic diseases that cause serious clinical symptoms to patients and affect their health and quality of life. Sclerotherapy has become the first-line therapy for venous system diseases. However, there are problems such as incomplete fibrosis and vascular recanalization after sclerotherapy, and improper operation will cause serious adverse consequences. Therefore, exploring a safe and effective sclerotherapy strategy is essential for developing clinically successful sclerotherapy. To solve the above problems, we proposed a new sclerotherapy strategy with a dual mechanism of "vascular damage and plasmin (PLA) system inhibition." We intended to construct a novel cationic surfactant (AEOx-TA) by reacting tranexamic acid (TA), a parent structure, with fatty alcohol polyoxyethylene ether (AEOx) by ester bonds. AEOx-TA could damage vascular endothelium and initiate a coagulation cascade effect to induce thrombus. Furthermore, AEOx-TA could be degraded by esterase and release the parent drug, TA, which could inhibit the PLA system to inhibit the degradation of thrombus and extracellular matrix and promote the process of vascular fibrosis. In addition, such surfactant-based sclerosants have foam-forming properties, and they can be blended with polyvinyl alcohol (PVA) to prepare a highly stable foam formulation (AEOx-TA/P), which can achieve a precise drug delivery and prolonged drug retention time, thereby improving drug efficacy and reducing the risk of ectopic embolism. Overall, the novel cationic surfactant AEOx-TA provides a new avenue to resolve the bottleneck: surfactant sclerosants' efficiency is relatively low in the current sclerotherapy.

In April 2024, the World Health Organization/International Agency for Research on Cancer (IARC) published the global cancer statistics 2022 in the CA: Cancer Journal for Clinicians. This report focuses on the incidence and mortality of 36 cancers in 185 countries or territories worldwide, analyzing the differences of gender, geographic region, and the Human Development Index (HDI) level. It is estimated that in the year 2022, there were 19.96 million new cancer cases and 9.74 million cancer deaths worldwide. Lung cancer (2 480 301, 12.4%) was the most frequently diagnosed cancer in 2022, followed by female breast cancer (2 295 686, 11.5%), colorectal cancer (1 926 118, 9.6%), prostate cancer (1 466 680, 7.3%), and gastric cancer (968 350, 4.9%). Lung cancer (1 817 172, 18.7%) was also the leading cause of cancer death, followed by colorectal cancer (903 859, 9.3%), liver cancer (757 948, 7.8%), female breast cancer (665 684, 6.9%), and gastric cancer (659 853, 6.8%). With demographics-based predictions indicating that the number of new cases of cancer will reach over 35 million by 2050. The Beijing Office for Cancer Prevention and Control team has collated this report and briefly interpreted it in combination with the current situation of cancer incidence and mortality in China.

Traditional drugs for the treatment of abdominal tumors often do not have the ability to target tumors and destroy normal cells while killing tumor cells. Therefore, new therapies are urgently needed to accurately target and kill tumor cells. As a drug carrier, extracellular vesicles have the advantages of naturalness, biotaxis, and low side effects, so they have attracted much attention in the research on the treatment of abdominal tumors. In this paper, the research progress in mechanism of action of extracellular vesicle drug delivery system in the treatment of abdominal tumors such as gastric, liver, pancreatic, bile duct, colorectal, and ovarian cancers with an extracellular vesicle drug delivery system was reviewed, including inhibiting the growth of abdominal tumor cells, reversing the drug resistance of the tumor stem cells, inhibiting the exocytosis of chemotherapeutic drugs from the tumor cells, and remodeling the tumor immune microenvironment.

Objective:To investigate the efficacy of fixation through dual minimally invasive incisions and dual osseous channels with a loop titanium plate combined with a Dog-Bone titanium plate for acute Rockwood Ⅲ acromioclavicular dislocation in comparison with open reduction and fixation with a clavicular hook plate.Methods:A retrospective study was conducted to analyze the data of the 60 patients with acute type Ⅲ acromioclavicular dislocation who had been treated at Department of Orthopedics, Liaocheng People's Hospital from February 2019 to May 2022. There were 35 males and 25 females with an age of (43.2±8.0) years, and 34 left sides and 26 right sides affected. According to different surgical methods, they were divided into a double titanium plates group of 32 cases who had been treated by fixation through dual minimally invasive incisions and dual osseous channels with a loop titanium plate combined with a Dog Bone titanium plate and a hook plate group of 28 cases who had been treated by open reduction and internal fixation with a clavicle hook plate. The time from injury to operation was (2.1±1.3) d. The 2 groups were compared in terms of incision length, operation time, intraoperative bleeding, and visual analogue scale (VAS) pain score, Constant-Murley shoulder function score and the coracoclavicular distance on the affected side which were recorded preoperatively and at the last follow-up. Complications such as infection, loosening of internal fixation or secondary fracture were observed.Results:There was no statistically significant difference in the preoperative general data between the 2 groups, indicating comparability ( P > 0.05). All patients were followed up for (11.2±2.1) months. The incision length in the double titanium plates group [(3.5±0.3) cm] was significantly shorter than that in the hook plate group [(6.2±0.7) cm], and the intraoperative bleeding [(45.3±7.5) mL] in the former was significantly less than that in the latter [(64.1±6.2) mL] ( P < 0.05). However, there was no statistically significant difference in the operation time between the 2 groups ( P > 0.05). The VAS score [0.5 (0, 1.0) points] and Constant-Murley shoulder function score [(95.1±2.1) points] in the double titanium plates group were significantly better than those in the hook plate group [0.8 (0, 1.0) points, (86.0±4.4) points] at the last follow-up ( P < 0.05). However, there was no statistically significant difference between the 2 groups in the coracoclavicular distance on the affected side ( P > 0.05). Good acromioclavicular joint repositioning and fixation were achieved in all patients. There were no surgery-related complications except for sinus tract formation in one patient in the double titanium plates group. Conclusion:In the treatment of acute Rockwood Ⅲ acromioclavicular dislocation, fixation through dual minimally invasive incisions and dual osseous channels with a loop titanium plate combined with a Dog-Bone titanium plate is superior to open reduction and internal fixation with a clavicular hook plate, showing advantages of minimal invasion, better safety, less intraoperative bleeding, and faster joint function recovery.

Objective:To understand the current situation of female cancer survivors′ self-advocacy and analyze its influencing factors.Methods:Convenience sampling was used. From August to November 2021, 243 female cancer survivors from 10 tertiary A hospitals in Jiangsu Province were selected as the research objects. The general information questionnaire and the Female Self-Advocacy in Cancer Survivorship (FSACS)were used for the survey. Multiple stepwise linear regression was used to analyze the influencing factors of female cancer survivors′ self-advocacy rights.Results:The self-advocacy score of this group of female cancer survivors was (82.42±10.42); the results of multiple stepwise linear regression analysis showed that education level was an influencing factor for female cancer survivors′self-advocacy ( P<0.05), but age, marital status, number of children, work status, family monthly income, reimbursement method, illness time, disease diagnosis, and disease stage had nothing to do with female cancer survivors′ self-advocacy( P>0.05). Conclusions:Female cancer survivors′ self-advocacy is affected by their educational level.It is recommended that medical staff pay attention to patients with low education level, provide personalized guidance according to their conditions, and encourage them to actively obtain external information, seek effective communication and external support, so as to improve Self-advocacy ability.

Objective:To assess and compare the performance of limiting-antigen avidity enzyme immunoassay (LAg-Avidity EIA) and pooling PCR in the surveillance for recent infection rates of HIV-1 in men who have sex with men (MSM).Methods:Blood samples were collected from MSM selected through snowball sampling method in sentinel surveillance in 13 prefectures of Yunnan province from 2016 to 2017. The samples were tested for HIV-1 antibody. The confirmed positive samples were tested by LAg-Avidity EIA. The negative samples were tested by pooling PCR. The recent infection rates of HIV-1 were estimated by the algorithm based on LAg-Avidity EIA and pooling PCR respectively. The two results were compared.Results:During 2016-2017, a total of 5 363 blood samples were collected from MSM, in which 407 samples were HIV-1 positive (including 177 positive tested previously) and 4 956 samples were HIV-1 negative. A total of 211 samples(91.7%) were tested by LAg-Avidity EIA, 69 were confirmed to be recent infections. A total of 4 469 samples were tested by pooling PCR, 8 were confirmed to be acute infections. The recent infection rates of HIV-1 from 2016 to 2017 estimated by LAg-Avidity EIA were 3.36% and 4.84%, and the recent infection rates estimated by pooling PCR were 3.27% and 3.02% respectively. The differences in recent infection rates of HIV-1 estimated by the two algorithms were not significant.Conclusions:The recent infection rates of HIV-1 estimated by LAg-Avidity EIA and pooling PCR in sentinel surveillance in MSM in Yunnan had good consistency from 2016 to 2017. Using the two methods might have a better stability in continuous surveillance for recent infection rates of HIV-1.
