OBJECTIVES: To investigate the effect of Scleromitrion diffusum on gastric mucosal epithelial-mesenchymal transition (EMT) in rats with gastric precancerous lesion. METHODS: Fifty SD rats were randomly divided into blank control group (n=11), model control group (n=13), Scleromitrion diffusum (SD) group (n=13) and vitase group (n=13). Gastric precancerous lesion animal model was prepared by 1-methyl-3-nitro-1-nitrosoguanidine complex polyfactor method, and the drugs were administrated by gavage once a day for 6 weeks. The pathological changes of gastric mucosa were observed with hematoxylin and eosin staining, the expression of EMT marker proteins were detected with immunohistochemical staining and Western blotting. RESULTS: Compared with the model control group, the gastric mucosal injury was significantly attenuated in the Scleromitrion diffusum group, the mucosal tissue structure gradually recovered, the saccular expansion area was reduced, and the inflammatory infiltration was ameliorated. The expression of epithelial cadherin was higher, and the expression of neural cadherin and vimentin in the Scleromitrion diffusum group were lower than those of model control group (all P<0.05). CONCLUSIONS Scleromitrion diffusum can ameliorate gastric mucosal injury in rats with gastric precancerous lesion by reversing the EMT.

Objective:To analyze the value of abdominal CT angiography (CTA) and three-dimensional reconstruction fusion technology for larger (2 - 5 cm) gastric submucosal tumors (SMT) in the preoperative evaluation of super minimally invasive surgery(SMIS).Methods:A retrospective study was conducted, collecting data from 20 patients with gastric SMTs measuring 2 - 5 cm in diameter who were hospitalized in the the First Medical Center of the Chinese PLA General Hospital from March 2023 to December 2024. All patients underwent abdominal CTA prior to SMIS, and three-dimensional reconstructions of the tumors were performed. Clinical data were collected to analyze the visualization of the tumors and surrounding blood vessels in the fused three-dimensional images and the corresponding surgical plans.Results:In 19 cases, the abdominal CTA and three-dimensional imaging clearly and intuitively displayed the anatomical structures surrounding the tumors and provided panoramic images of small blood vessels around the tumors, enabling the selection of appropriate surgical plans. One case required conversion to laparoscopic surgery due to the intraoperative discovery of a small artery.Conclusions:The abdominal CTA examination and gastric SMT three dimensional reconstruction before SMIS can better display the anatomical location of the tumor and its relationship with surrounding small blood vessels, which is beneficial for gastroenterologists to formulate surgical plans and facilitate the smooth progress of SMIS under endoscopy.

Objective:To construct a triple pre-rehabilitation intervention program for patients undergoing radical prostatectomy, to provide a basis for promoting pre-rehabilitation in patients undergoing radical prostatectomy.Methods:Literature analysis was used to search domestic and foreign databases such as China National Knowledge Infrastructure, Wanfang, PubMed, etc, on triple pre-rehabilitation and rapid rehabilitation of patients undergoing radical prostatectomy, with a search time frame from January 1, 2013 to December 31, 2023. The Delphi expert letter consultation was conducted later, and the final draft of the triple pre-rehabilitation intervention program for patients with radical prostatectomy was finally formed.Results:A total of 20 experts completed 2 rounds of inquiries, all were female, with an age of (40.85 ± 5.40) years old. The response rates for the 2 rounds of expert inquiries were both 100%(20/20). The authority coefficients of the experts were 0.87 and 0.90, respectively. Kendall coordination coefficients were 0.11 and 0.21, respectively. The coefficient of variation for each item in the second round of inquiries ranged from 0 to 0.15. The triple pre-rehabilitation intervention program for patients with radical resection of prostate cancer was constructed, including 4 primary indexes, 8 secondary indexes and 25 tertiary indexes.Conclusions:It is scientific, targeted and feasible to construct a triple pre-rehabilitation intervention program for patients undergoing radical prostatectomy based on Delphi method, which can provide clinical basis for pre-rehabilitation of elderly patients undergoing prostate cancer surgery.

The outbreak of COVID-19 has spread quickly across 114 countries/territories/areas in six continents worldwide and has been announced as a pandemic by WHO. This study analyzed global COVID-19 epidemiological trends, examined impact of the pandemic on global health security, diplomacy, and social environment in China, and provided short- and long-term strategic policy recommendations for China’s subsequent preparedness and responses.

Public Health Emergency Operation Center (PHEOC) was conceptualized and established for coordinating information and resources towards goal-oriented response in large scale public health emergency. Yet, the activities undertaken by PHEOCs and their intended goals have not been fully optimized in current scenario. This paper revisited the collective efforts invested in PHEOC conceptualization and development, identified the opportunities and challenges in compliance with standards and framework, demonstrated the accountability of PHEOC network, thereby promoted best practice guidance for global public health emergency preparedness and response. This review will help navigate emergency response complexities leveraging PHEOC partnerships and advance the ability to detect and respond to public health emergencies in low resource settings. The review shows that the information on how to adapt best practice guidance to local circumstances could incentivize the full implementation of prevention, early detection and response to outbreaks. Identifying and correcting deficiencies in effectiveness evaluation will provide the basis for continuous PHEOC improvement. With the gradually reopening economies and public services in some countries, there is an urgent need to emphasize and validate the collective efforts undertaken by PHEOCs for tackling the COVID-19 pandemic.

OBJECTIVETo investigate the effect of astragaloside IV (As IV) on the activation of rennin-angiotensin system in rats with pressure-overload induced cardiac hypertrophy.

METHODLeft ventricle hypertrophy was induced by abdominal aorta banding between bilateral renal aortas for 12 weeks. Rats were given astragaloside IV 1.0 mg x kg(-1) and 3.3 mg x kg(-1) for 12 weeks, respectively. After treatment, the left ventricular mass index (LVMI)was calculated by morphometry methods. Plasma and cardiac tissue angiotensin II, and plasma aldosterone were measured by ELISA method. Gene expressions of ACE, AT1 and AT2 in cardiac tissue were detected by real time PCR. Protein expressions of AT1 and AT2 in cardiac tissue were detected by Western blot.

RESULTCompared with model rats, LVMI was decreased by astragaloside IV treatment. Biochemical results indicated that the contents of angiotensin II in plasma and cardiac tissue as well as aldosterone in plasma were all increased in abdominal aorta banding rats comparing with sham-operated rats, then, decreased by astragaloside IV treatment. Gene expressions of cardiac ACE was downregulated by astragaloside IV, however, gene and protein expressions of cardiac AT2 were upregulated by astragaloside IV. Both elevated gene and protein expressions of AT1 were not attenuated by astragaloside IV.

CONCLUSIONExcessive activated rennin-angiotensin system in rats with pressure-overload induced cardiac hypertrophy is inhibited by astragaloside IV treatment.
