Objective:To clarify the changes of intrahepatic ultrasound hemodynamics before and after hepatic artery thrombosis (HAT) after liver transplantation (LT), providing early warning and anticoagulation guidance to clinicians.Methods:The clinical data of patients who underwent liver transplantation at Zhongshan Hospital of Fudan University between June 2006 and October 2022 were retrospectively analyzed, 47 patients with a diagnosis of HAT confirmed by DSA (digital subtraction angiography) were included in the HAT group, and 71 patients without vascular complications were included in the non-HAT group. Differences in peak flow velocity (PSV), resistance index (RI), and portal vein velocity (PVV) were compared between the two groups. Logistic regression analysis was used to determine the relationship between postoperative PSV decline and HAT occurrence, while ROC curve were used to determine the critical value and evaluate the diagnostic efficacy. Patients with HAT were divided into well-treatment group and poor-treatment group according to whether the blood flow was restored after multiple surgeries or thrombolytic treatments. The changes of early intrahepatic hemodynamics after surgical or thrombolytic therapy were compared between the two groups.Results:①A decrease in PSV of the transplanted hepatic artery was measured 1 d before HAT, and PSV<0.39 m/s predicted thrombus formation with a sensitivity of 0.70, specificity of 0.86, and the AUC was 0.83. ②After treatment, PSV in the HAT group increased immediately, approaching the normal level on the 2nd day. In the well-treatment group, PSV and PVV reached normal levels on the first day after treatment, which were significantly higher than the corresponding values in the poor-treatment group ( P=0.030, 0.021). Conclusions:In the early stage after liver transplantation, a PSV<0.39 m/s is related to the occurrence of HAT thrombosis 1 d later. A significant increase in PSV on the first day after treatment indicates a good treatment response, and there is no need for further DSA re-examination or increasing the number of thrombolysis.

Objective:To evaluate the feasibility of using two-dimensional shear wave elastography (2D-SWE) based liver and spleen elastic hardness (L/S-SWE) in patients with liver cirrhosis, and to determine the exclusion and diagnostic thresholds for early identification of liver cirrhosis.Methods:A total of 574 patients with chronic hepatitis B (hepatitis B for short) were included in this study. The clinical characteristics, L-SWE and S-SWE of the patients were collected, and the differences between cirrhosis group ( n=311) and non cirrhosis group ( n=263) were analyzed. The success rate and stability of liver and spleen elastic surgery were evaluated in two groups. The receiver operating characteristic (ROC) curve was used to analyze the efficacy of L-SWE, S-SWE, aspartate aminotransferase to platelet ratio index (APRI) alone and in combination in diagnosing liver cirrhosis. By analyzing the ROC curve, the double threshold for excluding and diagnosing liver cirrhosis was determined. Results:There was a statistically significant difference in platelet count and APRI between the cirrhosis group and the non cirrhosis group (all P<0.05). In the feasibility assessment of 2D-SWE technology, the success rate and stability of liver and spleen elastic operation were relatively high (success rate: 97.2% vs 81.3%; stability: 0.92 vs 0.84), and the success rate and stability of L-SWE operation were slightly better than S-SWE. The success rate of S-SWE operation in the cirrhosis group was higher than that in the non cirrhosis group ( P<0.05). The correlation analysis results showed that L-SWE, S-SWE, APRI were positively correlated with liver tissue pathological grading ( r=0.677, 0.528, 0.149, all P<0.05). The areas under the ROC curve for identifying liver cirrhosis using L-SWE, S-SWE, and APRI were 0.959, 0.896, and 0.706, respectively. When L-SWE and S-SWE were combined, the area under the ROC curve was 0.987, the sensitivity was 92.6%, and the specificity was 96.0%. The Delong test showed that the combined diagnosis of L-SWE and S-SWE had the same diagnostic efficacy as using L-SWE alone for liver cirrhosis ( P>0.05). Further analysis of the ROC curve showed that the likelihood of liver cirrhosis was low when L-SWE was less than 9.4 kPa, and high when L-SWE was greater than 12.0 kPa. Patients between 9.4 and 12.0 kPa can undergo further S-SWE testing; If the S-SWE was between 17.5 and 29.3 kPa, it was classified as 2D-SWE, which was difficult to determine whether there was liver cirrhosis, and further liver puncture and other examinations were needed. Conclusions:2D-SWE technology has high operational feasibility in the diagnosis of liver cirrhosis, and combined with S-SWE, it helps to improve the diagnostic efficiency of early non-invasive identification of liver cirrhosis, enabling more patients to avoid unnecessary liver puncture examinations.

Objective To study the properties and antimicrobial activity of the novel self-assembled antimicrobial peptide(AMP)CR-16,and to provide experimental evidence for the treatment of bacterial infections.Methods CR-16 was designed and synthesized based on the structure of antimicrobial peptides Buforin Ⅱ and LfcinB.Dynamic light scattering(DLS),transmission electron microscopy(TEM),and X-ray diffraction(XRD)were used to characterize CR-16.Based on the results of critical micelle concentration(CMC),the self-assembled properties of CR-16 were investigated using atomic force microscopy(AFM)and circular dichroism(CD).The minimum inhibitory concentration(MIC)was used to study the inhibitory effect of CR-16 while transmission electron microscopy(TEM)was adopted to observe the interactions between CR-16 and the outer membrane of bacteria.Results AMP CR-16 was prepared as self-assemblies,which were regularly spherical in shape and stable in activity.CR-16 could inhibit both the growth of Escherichia coli and,more importantly,the growth of NDM-1-producing carbapenem-resistant Escherichia coli,promising good prospects in treating infections caused by antibiotic-resistant bacteria.Conclusion CR-16 can be self-assembled and deliver antibacterial effects against Escherichia coli.

Objective To enhance the photostability of colchicine(COL)for sustained-release COL pellets.Methods The degradation was investigated by studying the photochemical degradation kinetics of COL.The impact of such physical properties of the photostabilizers as the type,color,dosage,and position on the photostability of COL in sustained-release pellets was also evaluated.Results The contents of photochemical degradation products did not increase after 10 days of light exposure to sustained-release COL pellets with red iron oxide of 4％(w/w)as the protective layer.Conclusion The findings of this study indicate that use of iron oxide as a photostabilizer in sustained-release COL pellets can significantly reduce the photochemical degradation of COL in the pellets.

Objective:To explore the impacts of thermotherapy combined with gemcitabine on the biological behavior of tongue squamous cell carcinoma cells.Methods:Human tongue squamous cell carcinoma Tca8113 cells were divided into the control group (blank control), gemcitabine group, thermotherapy group (heated in an incubator at 43℃ for 1 h and then incubated at 37℃ for 24 h) and thermotherapy + gemcitabine group. The proliferation ability of Tca8113 cells was assessed by EdU staining and CCK-8 assay. Cell apoptosis and cell cycle of Tca8113 cells were detected by flow cytometry. The invasion of Tca8113 cells was determined by Transwell chamber assay. The expression levels of cyclin D1 (CyclinD1), Bcl-2-associated X protein (Bax), matrix metalloproteinase (MMP)-9, phosphorylated histone H2AX (γH2AX) and Nijmegen breakage syndrome 1 (NBS1) proteins in Tca8113 cells were measured by Western blot. The changes of tumor mass and volume were detected by xenograft tumor in vivo test in nude mice. Multi-group comparison was performed by one-way ANOVA. Two group comparison was conducted by SNK- q test. Results:Compared with the control group, EdU positive cell percentage, OD 450 value, invasive cell number, CyclinD1, MMP-9 and NBS1 protein expression of Tca8113 cells were decreased, whereas the apoptosis rate, the expression of Bax and γH2AX proteins were increased in the gemcitabine, thermotherapy and thermotherapy + gemcitabine groups ( q=4.45-72.06, all P<0.001). Compared with the control group, the proportion of G 0/G 1 phase cells was decreased, whereas the proportion of S and G 2/M phase cells was increased in the gemcitabine and thermotherapy + gemcitabine groups, the proportion of G 0/G 1 phase cells was decreased and the proportion of G 2/M phase cells was increased in the hyperthermia group ( q=10.36-61.09, all P<0.001). Compared with the gemcitabine and thermotherapy groups, EdU positive cell percentage, OD 450 value, G 0/G 1 phase cell proportion, invasive cell number, CyclinD1, MMP-9 and NBS1 protein expression of Tca8113 cells were decreased, whereas apoptosis rate, S, G 2/M phase cell proportion, Bax and γH2AX protein expression were increased in the thermotherapy + gemcitabine group ( q=4.45-28.73, all P<0.001). Xenograft tumor in vivo test in nude mice showed that the tumor volume and mass of nude mice in the gemcitabine, thermotherapy, and thermotherapy + gemcitabine groups were decreased compared with those in the control group ( q=5.58-73.02, all P<0.001). Compared with the gemcitabine and thermotherapy groups, the tumor volume and mass in the thermotherapy + gemcitabine group were decreased ( q=5.58-21.45, all P<0.001). Conclusion:The combination of thermotherapy and gemcitabine can inhibit the proliferation and invasion, block the cell cycle, and induce cell apoptosis of Tca8113 cells.

Objective:To evaluate the effect of age factor on the potency of cisatracurium-induced neuromuscular block in the obese patients.Methods:American Society of Anesthesiologists Physical Status classification Ⅰ-Ⅲ obese patients, with a body mass index of 30-35 kg/m 2 and waist circumference (female ≥ 80 cm, male ≥ 90 cm), 40 elderly patients (age 65-75 yr) and 40 young and middle-aged patients (age 18-64 yr), scheduled for elective surgery with general anesthesia, were included in this study. Based on the random number table method, the patients were assigned into dosage groups of 40, 50, 60 and 70 μg/kg, served as OF1-4 groups and YF1-4 groups, with 10 patients in each group. The consumption of cisatracurium was calculated based on fat-free mass using a single-dose method. The neuromuscular block of cisatracurium was monitored by recording the response of the adductor pollicis muscle to TOF stimulation, the maximum suppression degree of T 1 and onset time were recorded using the Mindray BeneVision N17 monitor, and the dose-response relationship regression equation was developed to calculate the median effective dose. Results:There was no significant difference in the onset time among groups ( P>0.05). The median effective dose in elderly obese patients and young and middle-aged obese patients were 50.01 and 48.71 μg/kg, respectively, and there was no significant difference between the two groups ( P>0.05). Conclusions:There is no significant difference in the potency of cisatracurium-induced neuromuscular block between elderly obese patients and young and middle-aged obese patients, suggesting that age factor has no significant effect on it.

Xiaoruwan is one of the classic prescriptions included in the Catalogue of Ancient Classic Prescriptions （the Second Batch of Pediatrics） published by the National Administration of Traditional Chinese Medicine（TCM） in 2022 with definite clinical efficacy， but it has not been converted into Chinese patent medicine preparations. The authors collected 173 pieces of data based on ancient literature on Xiaoruwan by the method of bibliometrics and selected 99 pieces of effective data， involving 46 ancient books of TCM. The study analyzed the historical development origin， prescription names， formulation rules， dosage， drug origin， preparation method and usage， indications and functions， and other aspects of Xiaoruwan. The results showed that Xiaoruwan was presumably derived from Ying Hai Miao Jue Lun（《婴孩妙诀论》） written by TANG Minwang， a doctor in the Song Dynasty. In the records of ancient medical books， there are names such as Xiaoshiwan，Yangshi Xiaoruwan， and Kuaige Xiaoshiwan， but they are mainly recorded in the name of Xiaoruwan. The prescription was composed of Cyperi Rhizoma， Amomi Fructus， Citri Reticulatae Pericarpium， Massa Medicata Fermentata， Hordei Fructus Germinatus， and Glycyrrhizae Radix et Rhizoma. In terms of processing method， Cyperi Rhizoma， Massa Medicata Fermentata， and Hordei Fructus Germinatus are fried， Glycyrrhizae Radix et Rhizoma is processed， and raw materials of Amomi Fructus and Citri Reticulatae Pericarpium are used directly. In terms of function， it is effective in warming the middle， improving digestion， stopping vomiting， and digesting milk and food. The main indications include vomiting， diarrhea， night crying， and other diseases caused by milk and food stagnation. The dosage of the most used prescription in the records of ancient books is Cyperi Rhizoma 41.30 g， Amomi Fructus 20.65 g， Citri Reticulatae Pericarpium 20.65 g， Massa Medicata Fermentata 20.65 g， Hordei Fructus Germinatus 20.65 g， and Glycyrrhizae Radix et Rhizoma 20.65 g， which are prepared into pills.
