Turning to critical illness is a common stage of various diseases and injuries before death. Patients usually have complex health conditions, while the treatment process involves a wide range of content, along with high requirements for doctor′s professionalism and multi-specialty teamwork, as well as a great demand for time-sensitive treatments. However, this is not matched with critical care professionals and the current state of medical care in China. Telemedicine, which shortens the distance of medical professionals and the gap of disease diagnosis and treatments in various regions through electronic information, can effectively solve the current problem. Therefore, there is an urgent need to develop a standardized, high-quality visualization telemedicine round system .Therefore, experts have been organized to search domestic and foreign literature on telemedicine round for critically ill patients and to form this consensus based on clinical experiences so as to further improve the level of critical care treatments in regions.

Objective:To analyze the incidence and influencing factors of lymphopenia in prostate cancer patients undergoing pelvic radiotherapy.Methods:A retrospective analysis was conducted on 123 prostate cancer patients treated at the Department of Radiation Oncology, Peking University First Hospital, from November 2011 to May 2015. Radiotherapy was administered using conventional fractionated intensity-modulated radiotherapy. Blood routine, including absolute lymphocyte count (ALC), was performed on patients before radiotherapy, weekly during radiotherapy, and at the end of radiotherapy. Severe lymphopenia was defined as an ALC <500 cells/μl. Based on whether the minimum ALC during radiotherapy was lower than 500 cells/μl, the entire cohort and 55 patients (excluding those with undelineated pelvic bone marrow due to radiotherapy planning system issues) with delineated pelvic bone marrow (divided into pelvic bone marrow, iliac bone marrow, and lower pelvic bone marrow) were stratified into a severe lymphopenia group (33 cases and 16 cases, respectively) and a mild lymphopenia group (90 cases and 39 cases, respectively). Differences in clinical factors and dosimetric parameters were compared between the groups using the chi-square test (or Fisher's exact test), t-test, and Wilcoxon rank-sum test. Univariate and multivariate logistic regression analyses were performed to identify the clinical and dosimetric factors influencing severe lymphopenia. Results:All 123 prostate cancer patients experienced lymphopenia during radiotherapy, with a median minimum ALC of 0.6×10 9/L [range: (0.2-2.3)×10 9/L]. Severe lymphopenia occurred in 26.8% (33 cases) of patients. Univariate analysis of the entire cohort showed that pre-radiotherapy baseline ALC, initial neutrophil-to-lymphocyte ratio, prostate-specific antigen value, Gleason score, and pelvic radiotherapy were promoting factors for severe lymphopenia ( P<0.05). Multivariate analysis identified pre-radiotherapy baseline ALC ( OR=0.217, 95% CI: 0.072-0.650, P=0.006) and pelvic radiotherapy ( OR=23.852, 95% CI: 2.834-200.787, P=0.004) as promoting factors for severe lymphopenia. In patients with delineated pelvic bone marrow, univariate analysis showed that pelvic bone marrow V 30 Gy and V 40 Gy, iliac bone marrow V 30 Gy and V 40 Gy, lower pelvic bone marrow V 30 Gy and V 40 Gy were promoting factors for severe lymphopenia during treatment ( P<0.05). Conclusions:Lymphopenia is common in prostate cancer patients undergoing radiotherapy, with a high incidence of severe lymphopenia. Pre-radiotherapy baseline ALC, as well as pelvic, iliac, and lower pelvic bone marrow V 30 Gy and V 40 Gy, are promoting factors for severe lymphopenia during radiotherapy.

Background and aims Adeno-associated virus (AAV) is becoming an attractive vector due to its low toxicity and minimal immunogenicity. However, liver-targeted AAV gene therapy still faces challenges, such as low delivery efficiency and safety risks associated with high vector doses. Isolated hepatic perfusion (IHP) has been explored as a localized drug delivery method, yet its full potential in gene therapy remains under investigation. Here, we investigated the efficiency of AAV8 delivery via the IHP route and its preference for hepatic transduction. Methods The IHP route was established through surgery in rats and cynomolgus monkey, and the AAV8-dTomato solution was injected into the entire liver through the inflow tract and maintained for 10 min. One week later, liver tissues were obtained, and the dTomato fluorescence expression area fraction and intensity were analyzed. Results AAV8-dTomato delivery via the IHP resulted in over 60% dTomato-positive areas in rat liver and showed higher efficiency than the portal vein (PV) and inferior vena cava (IVC) routes at equivalent doses. In rats, AAV8-dTomato expression was primarily periportal across IHP, PV, and IVC routes, while in cynomolgus monkey, IHP delivery showed a pericentral pattern. Conclusions In this study, we found that IHP is an effective strategy for AAV8 delivery. In addition, the distribution characteristics of AAV8, when delivered in cynomolgus monkey via IHP, provide candidate vector delivery schemes for gene therapy for different types of genetic liver diseases.

Objective:To distinguish Hedyotis diffusa Willd. and its common countrerfeit, Hedyotis corymbosa. and Hedyotis tenelliflora. by analyzing and comparing their macroscopical identification, microscopic character and HPLC fingerprints. Methods:The features of macroscopical identification, microscopic character including cross-sections of stem, leaf, fruit and seed, and herbal powders were observed in the three samples by traditional methods. The difference of chromatographic peaks among the three samples were also analyzed by HPLC methods.Results:The stems of Hedyotis diffusa Willd. were cylindrical, and the capsules were solitary or double born in the leaf axils, oblate, 2-3 mm in diameter, with a long petiole; the Hedyotis corymbosa. and Hedyotis tenelliflora. were tetragonal, and the Hedyotis corymbosa. was 2-5 capsules born in leaf axils in corymbose inflorescences, globular, 1-1.5 mm in diameter, with a slender petiole; the Hedyotis tenelliflora. were 1-3 capsules clustered in the leaf axils, ovoid with longitudinal ribs around the margin, about 1.5 mm in diameter, without the long petiole, about 1.5 mm in diameter, sessile, the edge of the leaf drying revolute long needle-like. Under the identification, the cross section of the Hedyotis diffusa Willd. stem was almost round, the middle vein of the leaves was protrusion below, the inner pericarp fiber layer consisted of two layers of fiber cells, the surface of the seed coat cells was polygon, and the wall was densely covered with small reddish brown or yellow-brown warty spots. The cross section of the Hedyotis corymbosa. stem was quadrilateral, the surface of the seed coat cell was polygon, the wall was wavy and curved, and there was no warty point on the wall. The middle veins of the Hedyotis tenelliflora. were slightly sunken in the upper part, but not protruding in the lower part; the endocarp fiber layer consisted of 8 to 13 layers of fiber cells. Moreover, the HPLC fingerprint analysis demonstrated substantial dissimilarities in the characteristic peaks of these herbs. Conclusion:The traditional and modern analysis technology show that there are some differences in the characteristics, microscopical cross section, the powder characteristics, which can effectively distinguish the Hedyotis diffusa Willd. and its two local varieties.

Objective:To establish auto verification rules for the routine coagulation assays,and to provide reference for clinical laboratories to improve the quality and efficiency of results verification.Methods:A total of 24,510 specimens of sodium citrate anticoagulation routine coagulation test from the laboratory departments of eight hospitals including the First Medical Center,Chinese PLA General Hospital during January to March 2020 were collected and randomly divided into a rule establishment group and a rule verification group,with 6,670 specimens in the rule establishment group,including 2,056 Delta checks,and 17,840 specimens in the rule validation group,including 3,210 Delta checks.The activities of prothrombin time(PT),activated partial thromboplastin time(APTT),fibrinogen(Fib),thrombin time(TT),D-dimer(DD)and/or antithrombin(AT)were detected by Stago STA R Max automatic coagulation analyzer and supporting reagents.Taking the manual verification results as the standard,the auto verification and manual false negative rate(invalid verification),false positive rate(invalid interception),pass rate,positive coincidence rate,negative coincidence rate,verification consistency rate and specimen turnaround time(TAT)of the two groups were calculated.Results:The auto verification rules and the application process were preliminarily established,including internal quality control,alarm information,auto verification scope,critical value and deviation value inspection.In the rule establishment group,the single item pass rate was 82.6%-92.4%,and the overall pass rate was 73.8%.The consistency rate between auto verification and manual verification was 98.2%,and the positive coincidence rate and negative coincidence rate were 24.4%and 73.8%,respectively.In the rule verification group,the single item pass rate was 86.4%-91.5%,and the overall review pass rate was 71.5%.By simulating the application of auto verification rules,the average TAT of two hospitals among the eight hospitals was shortened by 1.5 hours and 2.1 hours,respectively.Conclusion:The application of auto verification rules can reduce workload of manual verification,and significantly shorten the TAT,and improve the report efficiency of the laboratory.
