Objective:To compare the efficacy of oliceridine and sufentanil when combined with propofol for painless gastroscopy.Methods:In this randomized controlled trial, 66 patients of either sex, aged 18-64 yr, with a body mass index of 18-26 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅰor Ⅱ, scheduled for elective painless gastroscopy from September 2024 to November 2024, were divided into 2 groups ( n=33 each) using a table of computer-generated random numbers: sufentanil combined with propofol group (SP group) and oliceridine combined with propofol group (OP group). Sufentanil 0.1 μg/kg was intravenously injected in group SP, oliceridine 0.02 mg/kg was intravenously injected in group OP, and 1 min later propofol 2 mg/kg was intravenously injected in both groups. When the modified Observer′s Assessment of Alertness and Sedation score ≤ 1, the painless gastroscopy was performed. Heart rate, mean arterial pressure and peripheral oxygen saturation were recorded on admission to the operating room, immediately after insertion of the gastroscope, and at the end of procedure. The success of sedation, time of gastroscopy, emergence time, consumption of propofol and use of vasoactive drugs were recorded. The occurrence of adverse events such as respiratory depression, hypotension, dizziness and nausea was also recorded. Results:Compared with group SP, the incidence of respiratory depression was significantly decreased in group OP ( P<0.05). There was no statistically significant difference in the incidence of hypotension, dizziness and nausea and heart rate, mean arterial pressure and peripheral oxygen saturation at different time points between the two groups ( P>0.05). Conclusions:Oliceridine provides better efficacy than sufentanil when combined with propofol in painless gastroscopy.

Objective:To investigate the association between serum 25-hydroxyvitamin D [25(OH)D] levels and 24-h urinary calcium excretion (24-h UCaE) and hypercalciuria in Chinese adults.Methods:This cross-sectional study was conducted from March 2022 to March 2023 in nine cities in China and included 1 239 residents. Demographic characteristics were collected through questionnaires and physical examinations, fasting blood samples were assessed for bone metabolism indicators, and 24-h urine samples were used to determine the 24-h UCaE. Multiple linear regression analysis was used to explore the relationship between serum 25(OH)D and 24-h UCaE and bone metabolism indexes. The relationship between serum 25(OH)D and hypercalciuria was analyzed using a multiple logistic regression model combined with restricted cubic spline modeling.Results:The mean participant age was (47.9±18.1) years, of which 453 (36.6%) were male. The percentages of vitamin D sufficiency, insufficiency, and deficiency were 7.6% (94/1 239), 29.0% (359/1 239), and 63.4% (786/1 239), respectively. The multiple linear regression model showed that after adjusting for the covariates the 24-h UCaE gradually increased with higher levels of 25(OH)D ( P overall <0.001, P nonlinear <0.001). The logistic regression analysis revealed that compared with the vitamin D deficient group, the OR for the prevalence of hypercalciuria in the vitamin D sufficient and vitamin D insufficient groups were 3.290 (95% CI 1.745 to 6.202) and 3.742 (95% CI 2.458 to 5.697), respectively. The results of the restricted cubic spline modeling showed a positive nonlinear relationship between 25(OH)D and the prevalence of hypercalciuria ( P overall <0.001, P nonlinear <0.001). The prevalence of hypercalciuria increased when 25(OH)D was >17.00 μg/L and peaked at 26.71 μg/L, after which there was a decreasing trend in the prevalence of hypercalciuria with increasing 25(OH)D. Conclusion:Associations between serum 25(OH)D levels and urinary calcium excretion and the prevalence of hypercalciuria were observed in the Chinese adult population.

Acute symptomatic osteoporotic thoracolumbar compression fracture (ASOTLF) can lead to chronic low back pain, kyphosis deformity, pulmonary dysfunction, loss of mobility, and even life-threatening complications. Vertebral augmentation is currently the mainstream treatment method for this condition. In 2019, the Editorial Board of Chinese Journal of Trauma and the Spinal Trauma Group of Orthopedic Surgeons Branch of Chinese Medical Doctor Association collaboratively led the development of Clinical guideline for vertebral augmentation for acute symptomatic osteoporotic thoracolumbar compression fractures. Six years later, with advances in clinical diagnosis and treatment techniques as well as accumulating evidence in related fields, the 2019 guideline requires updating. To this end, the Spinal Trauma Group of Orthopedic Surgeons Branch of Chinese Medical Doctor Association, the Spinal Health Professional Committee of China Human Health Science and Technology Promotion Association, and the Minimally Invasive Orthopedics Professional Committee of Shaanxi Medical Doctor Association have organized experts in the field to develop the Clinical guideline for vertebral augmentation of acute symptomatic osteoporotic thoracolumbar compression fractures ( version 2025) , based on the latest evidence-based medical researches. This guideline incorporates 3 recommendations retained from the 2019 version with updated strength of evidence, along with 12 new recommendations. It provides recommendations from six aspects of diagnosis, pain management, treatment option selection, prevention of postoperative complications, anti-osteoporosis therapy, and postoperative rehabilitation, aiming to provide a reference for standard treatment of vertebral augmentation for ASOTLF in hospitals at all levels.

Objective To investigate whether the gastric juice volume(GV)of obese women who took carbohydrate 2 hours before operation was equal to or less than that of those who are not routine drinking.Methods Obese patients undergoing elective laparoscopic gynecological surgery under general anesthesia with BMI of 28-32 kg/m2 and ASA grade of Ⅰ-Ⅱ,aged 18-65 years old were selected.The patients were divid-ed into the carbohydrate group(CHO group)and the fasting group(Control group)by random number table method,with 51 cases in each group.The Control group was fasted from 11 pm before surgery,while the CHO group was given 300 mL of carbohydrate orally 2 hours before anesthesia.The main outcome measure was compared with a non-inferiority limit(△)of 17 mL and the mean difference in gastric juice volume between the two groups in the right lateral decubitus position(RLDP)examined by gastric ultrasound.The secondary outcome measures included CSA in right lateral position under gastric ultrasound,Perlas classification,GV/kg,gastric juice pH value,patient satisfaction and gastric emptying time.Results The mean difference of gas-tric juice volume was 7.18 mL(95％CI:-0.06 to 14.43),and the upper limit of 95％CI was lower than the preset non-inferiority limit(△=17.05 mL).There was no statistically significant difference in the mean(standard deviation)gastric juice volume between the control group and the CHO group[40(26,66)mL vs.58(34,65)mL;P=0.43].The gastric volume GV/kg was similar in the two groups(P=0.66),and there was no significant difference in the number distribution of Perlas grades between the two groups(P＞0.05).There was significant difference in patient satisfaction between the two groups(P＜0.05).Conclusion Ac-cording to the evaluation of gastric ultrasound,compared with fasting at midnight,300ml carbohydrate intake at 2 hours before surgery is not inferior to fasting at midnight in terms of gastric fluid volume in obese women as assessed by gastric ultrasound.

Objective:To investigate effect of Gehua Jiecheng Decoction on IL-6/JAK2/STAT3 signaling pathway in colon tissue of ulcerative colitis with"inflammatory to cancer transformation"(UC-UCAC)mice of spleen deficiency and damp-heat type.Methods:Ten from 80 SPF C57BL/6 male mice were randomly selected as blank group and other 70 mice were selected as model group.After establishment of spleen deficient damp-heat model,mice were randomly divided into model group(1st,2nd and 3rd cycle),Gehua Jiecheng Decoction high,medium and low doses groups and mesalazine group,with 10 pieces per group.UC-UCAC transformation model was further established with azo methane oxide solution(AOM)/sodium glucan sulfate(DSS).Each group was treated with corresponding drugs for 4 weeks.General state of mice was observed.Score of disease activity index(DAI)was calculated.HE staining was used to observe colonic mucosa pathology of mice.EGFR,IL-6,JAK2,STAT3 and p-STAT3 proteins and genes expressions in mice colon tissues were detected by Western blot,IHC and RT-qPCR,respectively.Results:Compared with blank group,mice in model group(3rd cycle)were generally in a worse state,colon mucosal tissue was cancerous,DAI score,target proteins and genes expressions were significantly increased(P<0.01).Compared with model group(3rd cycle),general state of mice in all treatment groups were restored and colonic tissues pathology were improved to some extent.Target proteins and genes expressions in other treatment groups were significantly decreased except for Gehua Jiecheng Decoction low-dose group(P<0.01).Conclusion:Gehua Jiecheng Decoction may destroy tumor inflammatory microenvironment,repair damaged colonic mucosa tissue,delay inflamma-tion-cancer transformation process and prevent UCAC by inhibiting activation of IL-6/JAK2/STAT3 signaling pathway.

Objective:This study conducted mosquito-borne viruses RNA screening and analysis of virus evolution characteristics on mosquito specimens collected in 2023 from Hunchun city, Jilin province, China.Methods:Firstly, morphological method were employed for mosquito specimen classification. Then, real-time fluorescence quantitative reverse transcription-polymerase chain reaction (qRT-PCR) was used to detect the RNA of six mosquito-borne viruses in the collected mosquitos, i. e., Banna virus (BAV), Kadipiro virus (KDV), Liaoning virus (LNV), Tahyna virus (TAHV), Getah virus (GETV) and Japanese encephalitis virus (JEV). And by sequencing, the viral genome sequence of positive samples was obtained.Results:A total of 5490 mosquito specimens were collected from Hunchun city, Jilin province, included 4400 Aedes vexans (80.15%), 1090 Anopheles sinensis (19.85%). A total of 41 groups were obtained by mixing samples according to the time, location, and mosquito species collected. qRT-PCR result showed that only the Aedes vexans sample with the number JLHC2321 was tested positive for LNV, while the remaining samples were tested negative for the detected viruses. According to the phylogenetic analysis of the segment 10 gene, this LNV strain had the closest genetic relationship with NE9731 and belonged to the type II branch. Meanwhile, the amino acid sequence analysis based on the coding sequence (CDS) in the segment 10 showed that JLHC2321 only had 2 amino acid differential sites with the GII reference strain NE9731.Conclusions:This study detected LNV for the first time in Aedes vexans in Hunchun city, and our result provide important basic data for the monitoring and prevention strategies of mosquito-borne viruses in the region.

Objective:To understand the situation of arboviruses carried by mosquito specimens in Daozhen county, Guizhou province.Methods:In July 2023, mosquito specimens were collected in Daozhen county, Guizhou province, using photocatalytic mosquito trap method. Reverse transcription polymerase chain reaction (RT-PCR) technology was used to detect the types of viruses carried by mosquitoes, and phylogenetic trees were constructed using the neighbor-joining method to analyze the phylogenetic position of the detected viruses.Results:A total of 5 313 mosquito specimens belonging to 2 genera and 2 species were collected in Daozhen county, Guizhou province, including 3 953 Culex tritaeniorhynchus, 1 355 Armigeres subalbatus, and 5 other mosquito species. The specimens were divided into 54 batches according to their species for grinding, nucleic acid extraction, and testing. Among them, 6 batches of Cx. tritaeniorhynchus specimens tested positive for flavivirus genus using universal primers, and further identification revealed that 5 batches were positive for Japanese encephalitis virus (JEV) nucleic acid, and 1 batch was positive for Tembusu virus (TMUV) nucleic acid. Phylogenetic analysis showed that the detected JEV strains were all genotype I and fell within the same evolutionary branch; the detected TMUV was located on the third branch of the evolutionary tree, with the main host source of the strains on this branch being mosquitoes. Conclusions:In the mosquito specimens collected in Daozhen county, Guizhou province in 2023, genotype I JEV and TMUV were detected, with TMUV being detected for the first time in mosquitoes in Guizhou province. It is essential to enhance the surveillance of JEV and TMUV to mitigate the potential public health risks they pose.
