Jiuwei Xifeng Granules have become a Chinese patent medicine in the market. Because the formula contains Os Draconis, a top-level protected fossil of ancient organisms, the formula was to be improved by replacing Os Draconis with Ostreae Concha. To evaluate whether the improved formula has the same effectiveness and safety as the original formula, a randomized, double-blind, parallel-controlled, equivalence clinical trial was conducted. This study enrolled 288 tic disorder(TD) of children and assigned them into two groups in 1∶1. The treatment group and control group took the modified formula and original formula, respectively. The treatment lasted for 6 weeks, and follow-up visits were conducted at weeks 2, 4, and 6. The primary efficacy endpoint was the difference in Yale global tic severity scale(YGTSS)-total tic severity(TTS) score from baseline after 6 weeks of treatment. The results showed that after 6 weeks of treatment, the declines in YGTSS-TSS score showed no statistically significant difference between the two groups. The difference in YGTSS-TSS score(treatment group-control group) and the 95%CI of the full analysis set(FAS) were-0.17[-1.42, 1.08] and those of per-protocol set(PPS) were 0.29[-0.97, 1.56], which were within the equivalence boundary [-3, 3]. The equivalence test was therefore concluded. The two groups showed no significant differences in the secondary efficacy endpoints of effective rate for TD, total score and factor scores of YGTSS, clinical global impressions-severity(CGI-S) score, traditional Chinese medicine(TCM) response rate, or symptom disappearance rate, and thus a complete evidence chain with the primary outcome was formed. A total of 6 adverse reactions were reported, including 4(2.82%) cases in the treatment group and 2(1.41%) cases in the control group, which showed no statistically significant difference between the two groups. No serious suspected unexpected adverse reactions were reported, and no laboratory test results indicated serious clinically significant abnormalities. The results support the replacement of Os Draconis by Ostreae Concha in the original formula, and the efficacy and safety of the modified formula are consistent with those of the original formula.

By employing the analytic hierarchy process(AHP), the CRITIC method(a weight determination method based on indicator correlations), and the AHP-CRITIC hybrid weighting method, the weight coefficients of evaluation indicators were determined, followed by a comprehensive score comparison. The grey correlation analysis was then performed to analyze the results calculated using the hybrid weighting method. Subsequently, a backpropagation-artificial neural network(BP-ANN) model was constructed to predict the extraction process parameters and optimize the extraction process for Shenxiong Huanglian Jiedu Granules(SHJG). In the extraction process, an L_9(3~4) orthogonal experiment was designed to optimize three factors at three levels, including extraction frequency, water addition amount, and extraction time. The evaluation indicators included geniposide, berberine, ginsenoside Rg_1 + Re, ginsenoside Rb_1, ferulic acid, and extract yield. Finally, the optimal extraction results obtained by the orthogonal experiment, grey correlation analysis, and BP-ANN method were compared, and validation experiments were conducted. The results showed that the optimal extraction process involved two rounds of aqueous extraction, each lasting one hour; the first extraction used ten times the amount of added water, while the second extraction used eight times the amount. In the validation experiments, the average content of each indicator component was higher than the average content obtained in the orthogonal experiment, with a higher comprehensive score. The optimized extraction process parameters were reliable and stable, making them suitable for subsequent preparation process research.

Objective: To evaluate the radiation dose, operational standardization, and image quality of computed tomography (CT) Ningbo City Medical Imaging Cloud Platform, so as to provide references for optimizing the quality of CT examinations. Methods: Six CT devices were randomly selected from the Ningbo City Medical Imaging Cloud Platform. Digital Imaging and Communication in Medicine (DICOM) image data from CT examinations of the head, neck, chest, and abdomen in males aged 36 to 60 years were collected from January 2023 to December 2024. The radiation dose levels were evaluated using the volume CT dose index (CTDIvol) and dose length product (DLP). The coefficient of variation (CV) of CTDIvol and scan length were calculated to assess scan stability. Operational standardization was evaluated using the redundancy rate of scan length and protocol matching degree. Imaging quality was assessed using the signal to noise ratio (SNR) and contrast to noise ratio (CNR). Results: A total of 28 897 DICOM images were collected, including 6 730 axial scans of the skull, 2 778 plain scans of the neck, 15 496 plain scans of the chest, and 3 893 plain scans of the abdomen. The typical values of CTDIvol and DLP radiation doses for the head, neck, and chest were all lower than the diagnostic reference levels. The maximum typical values of CTDIvol and DLP for the abdomen were 22.49 mGy and 941.45 mGy·cm, respectively, which were higher than the diagnostic reference levels. The CV values of CTDIvol and scan length ranged from 14.59% to 37.88% and from 8.27% to 44.96%, respectively. The scan stability of head CT was relatively poor, with CV values ranging from 21.74% to 37.88% and from 12.66% to 44.96%, respectively. The redundancy rate of scan length ranged from 6.02% to 74.40%, and the protocol matching degree ranged from 79.80% to 100.00%. The operational standardization of neck CT was relatively poor, with redundancy rates ranging from 45.70% to 74.40% and protocol matching degrees ranging from 79.80% to 95.36%. The mean SNR and mean CNR of the pulmonary arteries in the chest were relatively high, ranging from 15.81 to 17.65 and from 6.33 to 7.41, respectively. Conclusions The radiation doses from abdominal CT examinations on some CT devices exceed the diagnostic reference levels. The scan stability of head CT examinations and the operational standardization of neck CT examinations represent weak points in quality control. It is recommended to carry out targeted quality control training to enhance the overall quality level of CT examinations.

Objective:To explore the construction of abdominal aortocaval fistula (ACF) model in adenine-induced renal failure rats, and to provide a suitable animal model for subsequent mechanism and intervention researches.Methods:Adult female Sprague-Dawley rats (250-300 g) were fed with 0.75% adenine diet (renal failure group, n=60) and the same diet without adenine (control group, n=10) for 4 weeks, and the rats were randomly grouped by block randomization method with a ratio of 6∶1. Thirty rats in the renal failure group were randomly selected by block randomization method at a ratio of 1∶1 to undergo laparotomies to establish ACF models (renal failure+ACF group). The serum creatinine, blood urea nitrogen detection and Masson staining were used to evaluate the establishment of renal failure model. Small animal ultrasound imaging system was applied to verify the successful construction of the ACF model. After 6 weeks of ACF observation, blood samples were collected from the heart of rats, and ACF-vascular tissues were collected for pathological study (HE staining). Results:At 4 weeks of feeding, compared with the control group, serum creatinine [(63.8±23.5) μmol/L vs. (33.0±3.8) μmol/L, Z=3.651, P<0.001] and blood urea nitrogen [(13.1±6.9) mmol/L vs. (5.3±0.6) mmol/L, Z=3.254, P=0.001] in the renal failure group were both higher. Masson staining showed renal tubulointerstitial inflammatory cell infiltration, renal tubular epithelial cell atrophy, interstitial fibrosis and vascular injury. Five rats sacrificed after ACF surgeries, and the survival rate was 83.3%. Doppler ultrasound showed turbulent blood flow of arterial to venous shunt at the anastomosis of open ACF (23/25) in the renal failure+ACF group. HE staining showed typical eccentric neointimal hyperplasia in the outflow tract of ACF vein in the renal failure+ACF group. Conclusions:The adenine-induced ACF rat model is successfully constructed, and ACF shows typical eccentric neointimal hyperplasia. The ACF construction would provide a reliable animal model to study the mechanism and intervention of neointimal hyperplasia for autologous arteriovenous fistula.

Coronary perforation is when a contrast agent or blood flows outside a blood vessel through a tear in a coronary artery.In this case,we reported a case of percutaneous coronary intervention for coronary calcified lesions,which led to iatrogenic coronary perforation and cardiac tamponade after the use of Shockwave balloon to treat intracoronary calcified nodules,and the management of PCI-related CAP was systematically reviewed through the literature.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective: To evaluate the inhibitory effect of tumor vaccines in colon carcinoma model mice. Methods: Mouse bone marrow⁃derived dendritic cells（BMDCs）were stimulated by using CpG β⁃glucan nanoparticles（CNP）in vitro. The BMDCs were divided into PBS group，NP group（without CpG nanoparticles），Lysate group（MC38 cell lysate）and CpG group（CpG1826），which were determined for the expression of marker molecules on the surface by flow cytometry and for the contents of interleukin⁃6（IL⁃6）and IL⁃12p40 in the culture supernatant by ELISA. The tumor lysate nano⁃vaccine was pre⁃ pared by mixing 50 mg／mL tumor lysate（MC38 cell lysate）with 200 mg／mL CNP in a volume ratio of 1∶1，with which mice were subcutaneously immunized as Vaccine group. Vaccine group，PBS group，CNP group and Lysate group were im⁃ munized once a week，for three times in total. Mice were subcutaneously inoculated with MC38 cells，2 × 105 cells for each， in the right lower limb 1 h after the last immunization，and measured for tumor volume once every three days to plot the tumor growth curve. The ratios of CD3+ CD4+ T and CD3+ CD8+ T cells in the blood were analyzed by flow cytometry and the levels of tumor necrosis factor⁃α（TNF⁃α）and interferon γ（IFNγ）in the blood and spleen of mice were determined by ELISA. Results: CNP effectively increased the expression of CD11c+ CD80+，CD11c+ CD86+，CD11c+ MHC⁃Ⅱ+ and the secretion of IL⁃6 and IL⁃12p40 in BMDCs in vitro，which were significantly higher than those in other 4 groups（t = 4. 3 ~ 46. 2，each P < 0. 05）. Compared with that of the other three groups，the tumor volume of mice in Vaccine group decreased significantly（t =2.6~3.4，eachP <0. 05）；TherewasnosignificantdifferenceinCD3+ CD8+ TandCD3+ CD8+ Tcellratios（t = 0.5~ 1. 9，each P > 0. 05）；The content of IFNγ in blood increased significantly（t = 3. 8 ~ 4. 6，P < 0. 05），while thatof TNF⁃α showed no significant difference（t = 0. 4 ~ 2. 0，each P > 0. 05）；However，the contents of IFN γ and TNF⁃α in spleen increased significantly（t = 6. 3 ~ 13. 0，each P < 0. 001）. Conclusion The prepared nano⁃vaccine of tumor lysate improvedtheimmune level in mice and effectively inhibited the growth of colon carcinoma.

In this experiment, the PK/PD fitting model of Chuanxiong(Chuanxiong Rhizoma) in the treatment of rheumatoid arthritis was established in the form of acupoint combined with external application gel paste. Firstly, the rheumatoid arthritis model was induced by ovalbumin, and the articular fluid of rabbits was extracted by microdialysis. The pharmacokinetic process of Chuanxiong in rabbit articular fluid was analyzed by UPLC-MS/MS, and the pharmacokinetic model was established. The pharmacodynamic effects of Chuanxiong on inflammatory factors IL-1β, TNF-α, and IL-6 were analyzed by enzyme-linked immunosorbent assay(ELISA). The pharmacodynamic model was established, and the PK/PD model was obtained by fitting the data of pharmacokinetics and pharmacodynamics. The results of pharmacokinetics showed that the concentration of ligustrolide A in the articular cavity by drug administration on classical acupoint Zusanli(ST 36) was higher than that by Yanglingquan(GB 34), which reflected the advantage of typical acupoint, while ligustrazine concentration was higher after administration through Yanglingquan than through Zusanli, which was different from the traditional acupoint theory. The results of pharmacodynamics showed that the drug had lag effect. The PK/PD model was constructed by fitting the data. When IL-1β was taken as the efficacy index, the PK/PD models of Chuanxiong in typical acupoint Zusanli group, atypical acupoint Yanglingquan group, and non-acupoint group were E=115.28C_e/(3 316.72+C_e), E=108.73C_e/(2 993.47+C_e), and E=101.34C_e/(3 028.51+C_e). When TNF-α was taken as the efficacy index, the PK/PD models of Chuanxiong in typical acupoint Zusanli group, atypical acupoint Yanglingquan group, and non-acupoint group were E=68.31C_e/(3 285.16+C_e), E=59.27C_e/(2 919.86+C_e), and E=53.61C_e/(2 862.87+C_e). When IL-6 was taken as the efficacy index, the PK/PD models of Chuanxiong in typical acupoint Zusanli group, atypical acupoint Yanglingquan group, and non-acupoint group were E=59.92C_e/(3 461.17+C_e), E=58.34C_e/(2 723.51+C_e), and E=49.17C_e/(2 862.76+C_e). The parameters showed that there were significant differences in E_(max), EC_(e50) and k_(eo). The analysis of data found that the PK/PD fitting effect of Zusanli, a typical acupoint, was the best, which proved that it was still the best site for drug administration. To sum up, it shows that there may be bidirectional selectivity between drugs and acupoints.
