Objective To investigate the prevalence of Echinococcus infections in small rodents around human residential areas in Yushu City, Qinghai Province in 2023, so as to provide insights into precision echinococcosis control. Methods One or two quadrats, each measuring 50 m × 50 m, were randomly assigned in Shanglaxiu Township and Longbao Township, Yushu City, Qinghai Province on June 2023, respectively, and 300 plate-type mouse traps, each measuring 12.0 cm × 6.5 cm, were assigned in each quadrat. Small rodents were captured during the period between 10 : 00 and 18 : 00 each day for 4 days. Then, all captured small rodents were identified and dissected, and liver specimens with suspected Echinococcus infections were subjected to pathological examinations. The Echinococcus cytochrome c oxidase 1 (cox1) gene was amplified using PCR assay, and the sequence of the amplified product was aligned to that was recorded in the GenBank to characterize the parasite species. In addition, a phylogenetic tree of Echinococcus was generated based on the cox1 gene sequence using the neighbor-joining method. Results A total of 236 small rodents were captured in Shanglaxiu and Longbao townships, Yushu City, including 65 Qinghai voles and 51 plateau pikas in Shanglaxiu Township, and 62 Qinghai voles and 58 plateau pikas in Longbao Township, and there was no significant difference in the constituent ratio of small rodents between the two townships (χ2 = 0.294, P > 0.05). Seven plateau pikas and 12 Qinghai voles were suspected to be infected with Echinococcus by dissection, and pathological examinations showed unclear structure of hepatic lobules and disordered hepatocyte arrangement in livers of small rodents suspected of Echinococcus infections. PCR assay identified E. shiquicus DNA in 7 Qinghai voles, which were all captured from Shanglaxiu Township. Phylogenetic analysis showed that the cox1 gene sequence of Echinococcus in small rodents was highly homologous to the E. shiquicus cox1 gene sequence reported previously. Conclusion Plateau pika and Qinghai vole were predominant small rodents around human residential areas in Yushu City, Qinghai Province in 2023, and E. shiquicus infection was detected in Qinghai voles.

Objective To investigate the spatiotemporal distribution characteristics and potential influencing factors of newly diagnosed echinococcosis cases in Qinghai Province from 2016 to 2022, so as to provide insights into the formulation of the echinococcosis control strategy in Qinghai Province. Methods The number of individuals screened for echinococcosis, number of newly diagnosed echinococcosis cases, number of registered dogs and number of stray dogs were captured from the annual reports of echinococcosis control program in Qinghai Province from 2016 to 2022, and the detection of newly diagnosed echinococcosis cases was calculated. The number of populations, precipitation, temperature, wind speed, sunshine hours, average altitude, number of year-end cattle stock, number of year-end sheep stock, gross domestic product (GDP) per capita, and number of village health centers in each county (district) of Qinghai Province were captured from the Qinghai Provincial Statistical Yearbook, and county-level electronic maps in Qinghai Province were downloaded from the National Platform for Common Geospatial Information Services. The software ArcGIS 10.8 was used to map the distribution of newly diagnosed echinococcosis cases in Qinghai Province, and the spatial autocorrelation analysis of newly diagnosed echinococcosis cases was performed. In addition, the spacetime scan analyses of number of individuals screened for echinococcosis, number of newly diagnosed echinococcosis cases and geographical coordinates in Qinghai Province were performed with the software SaTScan 10.1.2, and the spatial stratified heterogeneity of the detection of newly diagnosed echinococcosis cases was investigated with the software GeoDetector. Results A total of 6 569 426 residents were screened for echinococcosis in Qinghai Province from 2016 to 2022, and 5 924 newly diagnosed echinococcosis cases were found. The detection of newly diagnosed echinococcosis cases appeared a tendency towards a decline over years from 2016 to 2022 (χ2 = 11.107, P < 0.01), with the highest detection in Guoluo Tibetan Autonomous Prefecture in 2017 (82.12/105). There were spatial clusters in the detection of newly diagnosed echinococcosis cases in Qinghai Province from 2016 to 2018 (Moran’s I = 0.34 to 0.65, all Z values > 1.96, all P values < 0.05), and the distribution of newly diagnosed echinococcosis cases appeared random distribution from 2019 to 2022 (Moran’s I = −0.09 to 0.04, all Z values < 1.96, all P values > 0.05). Local spatial autocorrelation analysis showed high-high clusters and low-low clusters in the detection of new diagnosed echinococcosis cases in Qinghai Province from 2016 to 2022, and space-time scan analysis showed that the first most likely cluster areas of newly diagnosed echinococcosis cases in Qinghai Province from 2016 to 2022 were mainly distributed in Yushu Tibetan Autonomous Prefecture and Guoluo Tibetan Autonomous Prefecture. GeoDetector-based analysis of the driving factors for the spatial stratified heterogeneity of detection of newly diagnosed echinococcosis cases in Qinghai Province showed that average altitude, number of village health centers, number of cattle and sheep stock, GDP per capita, annual average sunshine hours, and annual average temperature had a strong explanatory power for the spatial distribution of newly diagnosed echinococcosis cases, with q values of 0.630, 0.610, 0.600, 0.590, 0.588, 0.537 and 0.526, respectively. Conclusions The detection of newly diagnosed echinococcosis cases appeared a tendency towards a decline in Qinghai Province over years from 2016 to 2022, showing spatial clustering. Targeted control measures are required in cluster areas of newly diagnosed echinococcosis cases for further control of the disease.

High-quality development is the primary task of building a socialist modern country in an all-round way. Organ donation and transplantation in China are evolving from high-speed growth to high-quality development, which put forward new requirements for the safe, stable and healthy operation of Organ Procurement Organization (OPO). Safety is the foundation and prerequisite for achieving the goal of high-quality development. As an independent and comprehensive department, internal audit should create new achievements in the new era. The department should include OPO and organ donation into the scope of internal audit, shift the emphasis upon the overall development of organ donation. Besides, it should fully consider the actual situation in different places, conduct all-round, objective and fair evaluation, provide evaluation and consulting services for OPO to properly implement organ donation, and give full play to the supervision and prevention role of internal audit.

Objective:Cholangiocarcinoma (CCA) is a malignant tumor derived from bile duct epithelial cells with extremely poor prognosis. The Hippo-Yes-associated protein (YAP)/transcription activator with PDZ binding motif (TAZ) signaling plays a critical role in cancer stem cell biology. Previous studies have shown that the positive expression of YAP/TAZ in CCA predicts larger tumor size and unfavorable clinical outcomes. We aim to evaluate the prognostic value of YAP/TAZ detection in CCA patients.Methods:CCA patients who underwent radical resection were retrospectively analyzed at our institution from January 2011 to June 2016. Postoperative pathological specimens were scored by YAP/TAZ immunohistochemical staining. The prognostic value of YAP/TAZ was analyzed by multivariate Cox-proportional hazards model.Results:A total of 91 CCA patients were enrolled. During a median follow-up time of 11.0 months, 69.2% patients relapsed and 45.1% died. The median OS and DFS were 10.7 months and 8.8 months respectively. The YAP/TAZ dual positive patients owned a worse TNM stage ( P=0.015), poorer tissue differentiation ( P=0.007), and a higher CA199 than those in negative patients. Multivariate Cox analysis identified that YAP/TAZ dual positivity as a significant factor predicted poorer OS ( P=0.010) and DFS ( P=0.028) in CCA patients after radical resection. In subgroup analysis, YAP/TAZ combination also significantly predicted OS ( P=0.044) and DFS ( P=0.043) in CCA patients with positive lymphatic metastasis and/or surgical margin who required adjuvant therapy. Conclusions:YAP/TAZ positivity is an independent predictive factor for survival in CCA patients after radical resectiony.

OBJECTIVETo evaluate the role and value of Changhai fulcrum bending radiograph(CH-FBR) in curve flexibility assessment of adolescent idiopathic scoliosis(AIS) patients.
METHODSThirty-seven AIS patients treated between June 2012 and August 2013 were enrolled, including 31 female and 6 male patients whose age ranged from 10 to 19 years, averaged of 15.0 years. The assessment of radiographs included preoperative standing posterior-anterior radiograph, supine side-bending radiograph, traditional fulcrum bending radiograph, Changhai fulcrum bending radiograph and postoperative standing posterior-anterior radiograph. Postoperatively, radiographs were assessed at one week. The CH-FBR was performed at the lowest height and the optimized height which means the weight on the fulcrum touch the maximum. All measurements of angle were made with use of the Cobb method. The flexibility of the curve as well as the correction rate and fulcrum bending correction index (FBCI) were calculated for all patients. The maximum height of CH-FBR, basic weight and maximum weight were measured for all AIS. Paired t-tests were used to assess differences between preoperative and postoperative curves within group samples. The Pearson correlation coefficients were calculated using bivariate analysis between CH-FBR flexibility rate and correction rate, the maximum height of CH-FBR and maximum weight, the height changes of CH-FBR and weight changes.
RESULTSA total of 46 curves were involved in this study, including 28 thoracic and 18 thoracolumbar/lumbar curves. Preoperatively, the mean Cobb angle of the 46 structural curves was 47° ± 11°. Postoperatively, the mean Cobb angle was 11° ± 5°. Cobb's angle in supine side-bending(t = 7.2, P = 0.001), traditional fulcrum bending (t = 7.1, P = 0.001) and lowest height of Changhai fulcrum bending (t = 6.5, P = 0.001) were significantly different from the postoperative Cobb angle; Cobb's angle in traditional FBR (t = 11.0, P = 0.001) and lowest height of Changhai fulcrum bending (t = 13.6, P = 0.001) were significantly different from the optimized height CH-FBR Cobb angle. There was no significant difference found between traditional FBR Cobb angle and lowest height CH-FBR Cobb angle (t = 2.0, P = 0.051), optimized height CH-FBR Cobb angle and postoperative Cobb angle (t = 0.9, P = 0.36), lowest height CH-FBR Cobb angle and traditional FBR Cobb angle(t = 2.0, P = 0.051). The maximum height of CH-FBR, basic weight and maximum weight were (29.6 ± 1.4)cm,(20 ± 6)kg, and (40 ± 6) kg. Preoperatively, the mean Cobb angle of the 28 structural curves(main thoracic curves) was 46° ± 11°. Postoperatively, the mean Cobb angle was 12° ± 6°. Preoperatively, the mean Cobb angle of the 18 structural curves(thoracolumbar/lumbar curves) was 49° ± 12°. Postoperatively, the mean Cobb angle was 10° ± 5°. The results were same in 28 structural curves, 18 structural curves as well as 46 curves. Correlation analysis of 46 curves indicated that the maximum height of CH-FBR positively correlated with maximum weight (r = 0.69, r(2) = 0.47, P = 0.001), the height changes of CH-FBR positively correlated with weight changes on CH-FBR (r = 0.62, r(2) = 0.38, P = 0.001).
CONCLUSIONSCH-FBR is a more reliable and effective method than traditional FBR and supine side-bending for curve flexibility evaluation in AIS patients. Moreover, compared to the traditional FBR and side-bending radiograph, the flexibility suggested by the optimized height CH-FBR more closely approximates the postoperative result made by pedicle screws fixation and fusion.
