Objective:To investigate the current situation of the use of transjugular intrahepatic portosystemic shunt (TIPS) for portal hypertension, which should aid the development of TIPS in China.Methods:The China Portal Hypertension Alliance (CHESS) initiated this study that comprehensively investigated the basic situation of TIPS for portal hypertension in China through network research. The survey included the following: the number of surgical cases, main indications, the development of Early-TIPS, TIPS for portal vein cavernous transformation, collateral circulation embolization, intraoperative portal pressure gradient measurement, commonly used stent types, conventional anticoagulation and time, postoperative follow-up, obstacles, and the application of domestic instruments.Results:According to the survey, a total of 13 527 TIPS operations were carried out in 545 hospitals participating in the survey in 2021, and 94.1% of the hospital had the habit of routine follow-up after TIPS. Most hospitals believed that the main indications of TIPS were the control of acute bleeding (42.6%) and the prevention of rebleeding (40.7%). 48.1% of the teams carried out early or priority TIPS, 53.0% of the teams carried out TIPS for the cavernous transformation of the portal vein, and 81.0% chose routine embolization of collateral circulation during operation. Most of them used coils and biological glue as embolic materials, and 78.5% of the team routinely performed intraoperative portal pressure gradient measurements. In selecting TIPS stents, 57.1% of the hospitals woulel choose Viator-specific stents, 57.2% woulel choose conventional anticoagulation after TIPS, and the duration of anticoagulation was between 3-6 months (55.4%). The limitation of TIPS surgery was mainly due to cost (72.3%) and insufficient understanding of doctors in related departments (77.4%). Most teams accepted the domestic instruments used in TIPS (92.7%).Conclusions:This survey shows that TIPS treatment is an essential part of treating portal hypertension in China. The total number of TIPS cases is far from that of patients with portal hypertension. In the future, it is still necessary to popularize TIPS technology and further standardize surgical indications, routine operations, and instrument application.

A precursor ion selection (PIS) based ultra high performance liquid chromatography-quadrupole time of flight mass spectrometry (UHPLC-Q-TOF-MS) analytical method was used to screen the chemical components in Jiawei Dingzhi pills (JWDZP) comprehensively and rapidly. To compile the components of the compound medicine, a total of 1 921 components were found utilizing online databases and literature. After verifying the sources, unifying the component names, merging the multi-flavor attributed components, and removing the weak polar molecules, 450 components were successfully retained. The Acquity UPLC HSS T3 column (100 mm × 2.1 mm, 1.8 μm) was used, with a 0.1% formic acid water (A)-acetonitrile (B) as the mobile phase. The flow rate was 0.35 mL·min^-1, the column temperature was 35 ℃, and an electrospray ion source was used. Data was collected with the PIS strategy in both positive and negative ion modes. Compounds were screened through matching accurate molecular weight of the database, and identified according to MS/MS data (characteristic fragment ions and neutral loss), with comparison of reference. Some compounds were confirmed using standard products. A total of 176 compounds were screened out in the extract of JWDZP, among which 26 compounds were confirmed by standard products. These compounds include 96 components from the sovereign drug, and 34 coefflux components with low ion intensity. The PIS-UHPLC-Q-TOF-MS/MS method established in this study can quickly and comprehensively screen the chemical components of JWDZP, which enhanced the screening rate of components with co-elution compounds of low ion intensities and provided a basis for the study of the material foundation of JWDZP.

Objective:To compare the efficacy and safety of transcatheter arterial embolization (TAE) and Viabahn covered stent placement (CSP) for the treatment of delayed hemorrhage after hepatobiliary and pancreatic surgery (DH-HPS).Methods:The clinical data of 41 patients with DH-HPS at the Affiliated Hospital of Xuzhou Medical University from January 2019 to June 2023 were retrospectively analyzed. Among these patients, 27 were male and 14 were female, with an average age of (63.1±10.3) years. 22 patients who underwent TAE was in TAE group and 19 who underwent Viabahn CSP was in CSP group. The interventional treatment effect, blood biochemical indexes and complications were compared between the two groups.Results:In the TAE group, the success rate of hemostasis was 90.9% (20/22), and the rebleeding rate was 9.1% (2/22) after interventional treatment. In the CSP group, the success rate of hemostasis was 94.7% (18/19), and the rebleeding rate of was 5.3% (1/19) after interventional treatment. There was no statistically significant difference in the success rate of hemostasis and the rebleeding rate between the two groups (both P>0.05). The rate of liver function exacerbation after the procedure was 100% (20/20) in the TAE group and 58.8% (10/17) in the CSP group, with a statistically significant difference between the two groups ( χ2=9.77, P=0.002). 37 patients were followed up (18.4±1.7) months, and no rebleeding occurred in all patients. Conclusion:TAE and CSP are both effective for DH-HPS, while CSP is superior to TAE in terms of liver function protection.

Intermittent hypoxia (IH) is an important pathophysiological feature of obstructive sleep apnea (OSA), but its molecular mechanism is still unclear. We aim to investigate the role of endogenous competing endogenous RNA (ceRNA) regulatory network in the development of IH in OSA rats. An intermittent hypoxic rat model of OSA was constructed by hypoxic and reoxygenation cycles. CircRNAs and mRNAs were detected in rat bronchial tissues, and 230 up-regulated and 181 down-regulated circRNAs and 1238 up-regulated and 608 down-regulated mRNAs were analyzed and screened. The results of Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis of the differential circRNAs and mRNAs suggested that they were mainly associated with metabolic pathways and PI3K-Akt signaling pathways. The key circRNAs (the top six circRNAs with the largest differences) were further validated by quantitative real-time polymerase chain reaction (qRT-PCR), chr9:52042693| 52047844 and chr4: 64889575|64899587 were expressed in bronchial tissues consistent with the sequencing results, which were used to further construct the ceRNA regulatory network. Four potential ceRNA regulatory networks were identified by TargetScan and miRanda database, combined with the results of differential circRNA and mRNA. The expression of molecules in the four potential ceRNA regulatory networks was detected by qRT-PCR in bronchial and lung tissues, and the results suggested that the expression of this regulatory network, chr9:52042693|52047844-miR-351-5p-Pten, was consistent with the sequencing results. The findings indicate that chr9:52042693 | 52047844-miR-351-5p-Pten may be involved in the development and progression of obstructive sleep apnea syndrome through a ceRNA mechanism.

OBJECTIVE: The leukemia cells from patients with T-cell acute lymphoblastic leukemia (T-ALL) were inoculated into NCG mice to establish a stable human T-ALL leukemia animal model. METHODS: Leukemia cells from bone marrow of newly diagnosed T-ALL patients were isolated, and the leukemia cells were inoculated into NCG mice via tail vein. The proportion of hCD45 positive cells in peripheral blood of the mice was detected regularly by flow cytometry, and the infiltration of leukemia cells in bone marrow, liver, spleen and other organs of the mice was detected by pathology and immunohistochemistry. After the first generation mice model was successfully established, the spleen cells from the first generation mice were inoculated into the second generation mice, and after the second generation mice model was successfully established, the spleen cells from the second generation mice were further inoculated into the third generation mice, and the growth of leukemia cells in peripheral blood of the mice in each group was monitored by regular flow cytometry to evaluate the stability of this T-ALL leukemia animal model. RESULTS: On the 10th day after inoculation, hCD45⁺ leukemia cells could be successfully detected in the peripheral blood of the first generation mice, and the proportion of these cells was gradually increased. On average, the mice appeared listless 6 or 7 weeks after inoculation, and a large number of T lymphocyte leukemia cells were found in the peripheral blood and bone marrow smear of the mice. The spleen of the mice was obviously enlarged, and immunohistochemical examination showed that hCD3⁺ leukemia cells infiltrated into bone marrow, liver and spleen extensively. The second and third generation mice could stably develop leukemia, and the average survival time was 4-5 weeks. CONCLUSION Inoculating leukemia cells from bone marrow of patients with T-ALL into NCG mice via tail vein can successfully construct a patient-derived tumor xenografts (PDTX) model.

OBJECTIVE: To investigate the inflammatory effects of Cinobufotalin on monocytes in resting state and macrophages in activated state and its molecular mechanism. METHODS: THP-1 cells were stimulated with Phorbol 12-myristate 13-acetate to induce differentiation into macrophages. Lipopolysaccharides was added to activate macrophages in order to establish macrophage activation model. Cinobufotalin was added to the inflammatory cell model for 24 h as a treatment. CCK-8 was used to detect cell proliferation, Annexin V /PI double staining flow cytometry was used to detect cell apoptosis, flow cytometry was used to detect macrophage activation, and cytometric bead array was used to detect cytokines. Transcriptome sequencing was used to explore the gene expression profile regulated by Cinobufotalin. Changes in the significantly regulated molecules were verified by real-time quantitative polymerase chain reaction and Western blot. RESULTS: 1∶25 concentration of Cinobufotalin significantly inhibited the proliferation of resting monocytes(P<0.01), and induced apoptosis(P<0.01), especially the activated macrophages(P<0.001, P<0.001). Cinobufotalin significantly inhibited the activation of macrophages, and significantly down-regulated the inflammatory cytokines(IL-6, TNF-α, IL-1β, IL-8) released by activated macrophages(P＜0.001). Its mechanism was achieved by inhibiting TLR4/MYD88/P-IκBa signaling pathway. CONCLUSION Cinobufotalin can inhibit the inflammatory factors produced by the over-activation of macrophages through TLR4/MYD88/P-IκBa pathway, which is expected to be applied to the treatment and research of diseases related to the over-release of inflammatory factors.

Objective: To investigate the oncologic and surgical safety of the fused fascia method for immediate breast reconstruction with implants. Methods: The clinical data of 343 patients with immediate breast reconstruction with implants in Tianjin Medical University Cancer Hospital from 2014-2017 were retrospectively analyzed to compare the 5-year local recurrence-free survival, 5-year disease-free survival and 5-year overall survival of patients with breast reconstruction by fusion fascia and other methods, and to analyze the complication incidences of implant removal between different implant groups. Results: Of the 343 patients with breast reconstruction, 95 were in the fused fascia group (fascia group) and 248 were in the non-fascia group (25 in the bovine pericardial patch group and 223 in the muscle flap group). At a median follow-up of 49 months, the differences in 5-year local recurrence-free survival (90.1% and 94.9%, respectively), 5-year disease-free survival (89.2% and 87.6%, respectively), and 5-year overall survival (95.2% and 95.1%, respectively) between patients in the fascial and non-fascial groups were not statistically significant (P>0.05). The complication incidence of implant removal was 24.0% (6/25) in the patch group and 2.1% (2/95) and 2.2% (5/223) in the fascia and muscle flap groups, respectively. Conclusion: Immediate breast reconstruction with fused fascial combined with implant is safe and feasible, less invasive than muscle flaps, more economical and with fewer complications than patches.
