OBJECTIVE To conduct rapid health technology assessment (HTA) of ulinastatin (UTI), and to evaluate the efficacy, safety and cost-effectiveness of UTI in the treatment of acute pancreatitis (AP). METHODS Retrieved from PubMed, Embase, the Cochrane Library, CNKI, Wanfang database, CBM and official websites of HTA institutions, the systematic review (SR)/meta-analysis, economic evaluation and HTA reports of UTI in the treatment of AP were collected from the inception to Apr. 2024. Two researchers independently conducted screening, quality evaluation and data extraction according to the admission and exclusion criteria, and descriptive analysis was adopted to analyze and summarize the data. RESULTS A total of 19 studies were included, involving 15 SR/meta-analysis and 4 economic studies, and no HTA report was retrieved. In the treatment of AP, UTI showed clear advantages over conventional treatment alone in terms of improving the overall effective rate, shortening the recovery time of amylase, reducing the time required to relieve abdominal pain and distension, lowering the mortality rate, and decreasing the average hospital stay. Compared to other positive drugs (carbendate mesylate, octreotide, somatostatin, etc.), its efficacy is similar, with a favorable safety profile. As far as the current research was concerned, UTI had obvious economic advantages over other positive drugs. CONCLUSIONS UTI is safe and effective in the treatment of AP, and has economic advantages.

ObjectiveTo explore the clinical efficacy of compound Wufengcao liquid (CWL) on tuberculous ulcer and the influence on macrophage polarization. Method① Clinical experiment: A total of 145 patients with tuberculous ulcer who were treated in Nanjing Integrated Traditional Chinese and Western Medicine Hospital were randomized into observation group, control group Ⅰ, and control group Ⅱ according to the random number table method. In addition to the basic anti-tuberculosis chemotherapy, CWL, Kangfuxin liquid, and isoniazid solution (local external application) were respectively used in the observation group, control group Ⅰ, and control group Ⅱ. The treatment lasted 4 weeks for each group. The total effective rate in wound healing, traditional Chinese medicine(TCM) syndrome score, and histopathological morphology of wound were observed and the expression of inducible nitric oxide synthase (iNOS) and arginase-1 (Arg-1) in wound tissue was measured. ② Cell experiment: RAW264.7 cells were cultured in DMEM (10% fetal bovine serum, 1% double-antibody solution) in a cell incubator (37 °C, 5% CO2). Phorbol 12-myristate 13-acetate (PMA) was used to induce the differentiation of RAW264.7 cells into macrophages. Lipopolysaccharide (LPS) was employed to stimulate polarization of macrophages into M1 type and interleukin-4 (IL-4) to induce the polarization into M2 type. Kangfuxin solution, isoniazid solution, and CWL were respectively applied to the above cell model for 36 h. The cell supernatant was collected and centrifuged. Western blot was used to detect the protein expression of tumor necrosis factor-α (TNF-α), transforming growth factor-β (TGF-β), iNOS, and Arg-1, and flow cytometry (FCM) to detect the expression of CD86 and CD206. Result①Clinical experiment: The total effective rate in the CWL group [98.0% (48/49)] was higher than that in the control group Ⅰ [87.5% (42/48), χ2=3.962, P<0.05] and control group Ⅱ [83.3% (40/48), χ2=6.162, P<0.05]. After 28 days of treatment, compared with control group Ⅰ and control group Ⅱ, CWL decreased the TCM syndrome score (P<0.05) and obviously improved the histopathological morphology of the wound. Immunohistochemistry results showed that the iNOS expression in local focus tissue was lower (P<0.05) and the expression of Arg-1 was higher (P<0.05, P<0.01) in the CWL group than in the control group Ⅰ and control group Ⅱ after 28 days of treatment. ② Cell experiment: Western blot assay showed that the expression of iNOS and TNF-α in LPS group increased compared with that in the M0 group (P<0.01) and the expression in the LPS+ isoniazid group, LPS+ Kangfuxin group, and LPS+CWL group was lower than that in the LPS group (P<0.05). The expression of iNOS in LPS+Kangfuxin group and LPS+ CWL group was lower than that in the LPS+isoniazid group (P<0.05, P<0.01), and the expression of TNF-α in LPS+ CWL group was lower than that in LPS+isoniazid group (P<0.01). The expression of TNF-α in LPS+ CWL group decreased compared with that in the LPS+ Kangfuxin group (P<0.05). The expression of Arg-1 and TGF-β in IL-4 group was higher than that in the M0 group (P<0.01), and the expression in the IL-4+isoniazid group, IL-4+Kangfuxin group, and IL-4+ CWL group was higher than that in the IL-4 group (P<0.05). The expression of Arg-1 and TGF-β in the IL-4+ Kangfuxin group and IL-4+CWL group was higher than that in the IL-4+isoniazid group (P<0.05, P<0.01), and the expression was higher in the IL-4+CWL group than in the IL-4+Kangfuxin group (P<0.05, P<0.01). The FCM result showed that the expression of CD86 and CD206 in LPS group and IL-4 group was higher than that in M0 group (P<0.01). CD86 expression in LPS+isoniazid group, LPS+ Kangfuxin group, and LPS+CWL group was lower than that in the LPS group (P<0.01). The expression of CD86 in LPS+Kangfuxin group and LPS+ CWL group increased compared with that in the LPS+isoniazid group (P<0.01), and the expression was higher in the LPS+ CWL group than in the LPS+Kangfuxin group (P<0.01). CD206 expression in IL-4+ isoniazid group, IL-4+Kangfuxin liquor group, and IL-4+ CWL group was increased compared with that in the IL-4 group (P<0.01). CD206 expression in IL-4+Kangfuxin liquid group and IL-4+ CWL group was decreased compared with that in the IL-4+isoniazid group (P<0.01). CD206 expression in IL-4+CWL group was lower than that in the IL-4+ Kangfuxin group (P<0.05). ConclusionCWL can promote the healing of tuberculous ulcers, and the mechanism is that it inhibits the expression of iNOS, TNF-α, and CD86 and promotes the expression of Arg-1, TGF-β, and CD206, thereby regulating M1/M2 polarization balance.

【Objective】 To reduce the incidence of postoperative intestinal obstruction, we tried to improve surgical techniques by closing the cavity formed during radical cystectomy + ileal passage (Bricker) via laparoscopy to prevent the formation of abdominal hernia. 【Methods】 During Oct.2018 and Feb.2022, 41 patients were involved (conventional group). After standard laparoscopic radical cystectomy + pelvic lymphadenectomy, the ileum channel was established. The right medial retroperitoneum was sutured to cover the mesothelium and end of the ileum channel under open operation or endoscope. The space between the ureter and mesothelium of the ileum channel was sealed, and the end of the ileum channel and both ureters were externalized. During Feb.2022 and Dec.2022, 15 patients were involved (modified group). The right inner and outer lateral peritoneums below the ileal conduit were sutured to "bottom out" the gap between the ileal conduit and the right abdominal wall in addition to standard procedures. The recovery of intestinal function and incidence of bowel obstruction were compared between the two groups. 【Results】 In the conventional group, the intestinal function recovered within 2 to 6 days after surgery, with a median ventilation time of 3 days. Intestinal obstruction occurred in 3 patients, 2 of whom improved after conservative treatment while 1 underwent surgical exploration after ineffective conservative therapy. There were no significant differences in the time of discharge and ventilation between the two groups, but no intestinal obstruction occurred in the modified group. 【Conclusion】 Peritoneal externalization at the end of ileal passage can reduce the incidence of intra-abdominal hernia and postoperative intestinal obstruction, which is worthy of clinical application.

Objective:To evaluate the effect of mixed reality (MR) in the standardized resident training on oral and maxillofacial-head and neck tumor surgery.Methods:Twenty resident doctors, who received standardized training in the department of maxillofacial oncology of our hospital, were randomly divided into experimental group and control group. The MR teaching method was used in the experimental group, while the traditional teaching method was used in the control group. The teaching effect was evaluated by theoretical and operational tests and a questionnaire survey. Statistical analysis was performed with the SPSS 24.0 software. Statistical comparisons were performed by the Students' t-test or the Wilcoxon rank correlation test. Results:The theoretical test results showed that the scores of the experimental group were significantly higher than those of the control group (85.30±3.59 vs. 80.20±5.63, t = 2.41, P = 0.027). The operational test results showed that the scores of the experimental group were significantly higher than those of the control group (89.20±5.07 vs. 82.30±6.36, t = 2.68, P = 0.015). The questionnaire survey results showed that the MR teaching helped to easily acquire the knowledge of head and neck anatomy and operation skills. Besides, the doctors in the experimental group were more active and glad to communicate with others than those in the control group. In addition, the MR teaching method improved the learning interest of doctors. The doctors in the experimental group were more satisfied with the teaching effect than those in the control group, and they recommended that the MR teaching method be used in clinical training and teaching on oral and maxillofacial-head and neck tumor surgery. Conclusion:MR teaching can help doctors understand and master the knowledge of head and neck anatomy and operation skills and improve their learning interest, achieving a good teaching effect, so it has important application value in the standardized resident training on oral and maxillofacial-head and neck tumor surgery.

Objective:To explore the effect of mixed reality (MR) application in the reconstruction of mandibular defects.Methods:Eighteen patients with mandibular defects were enrolled in this study, including 10 male patients and 8 female patients, whose age ranged from 27 to 45 years, and the mean age was 35.4 years. All the patients were from the Stomatological Hospital of the Fourth Military Medical University, during October 2019 to May 2021. Fibular flaps were used for the reconstruction of the mandibular defects. The patients were randomly divided into three groups, six in each group. In group one, MR-guided mandibular defect repair and reconstruction technique was used. In group two, 3D printed guide-assisted mandibular defect repair and reconstruction technique was used, and in the control group, traditional jaw defect repair and reconstruction technique was used. All the procedures were performed by the same team. Cone beam computed tomography (CBCT) was used for analysis of surgical accuracy, and questionnaires were used to evaluate the outcome of medical communication, occlusal relationship, appearance restoration, and medical experience satisfaction.Results:The mean surgical errors in the group one and group two were (1.75±0.44) mm and (1.81±0.16) mm respectively, which were both significantly lower than that in the control group (3.05±0.83) mm ( tMR=3.38, t3D=3.56, P<0.01). The medical communication (4.60±0.35, 4.52±0.28, tMR=2.90, t3D=2.77, P<0.05), occlusal relationship (4.17±0.32, 4.28±0.39, tMR=3.07, t3D=3.29, P<0.05), and medical experience satisfaction scores (4.26±0.45, 4.25±0.67, tMR=2.50, t3D=2.26, P<0.05) in the experimental groups were significantly higher than those in the control group (4.02±0.34, 3.58±0.33, 3.56±0.32, respectively). There was no significant difference in the satisfaction of appearance recovery among all the groups ( P>0.05). Conclusions:MR-guided mandibular repair and reconstruction surgery has high accuracy and is also beneficial to the recovery of occlusal relationship and medical communication.

Pulmonary hypertension (PH) is an extremely malignant pulmonary vascular disease of unknown etiology. ADAR1 is an RNA editing enzyme that converts adenosine in RNA to inosine, thereby affecting RNA expression. However, the role of ADAR1 in PH development remains unclear. In the present study, we investigated the biological role and molecular mechanism of ADAR1 in PH pulmonary vascular remodeling. Overexpression of ADAR1 aggravated PH progression and promoted the proliferation of pulmonary artery smooth muscle cells (PASMCs). Conversely, inhibition of ADAR1 produced opposite effects. High-throughput whole transcriptome sequencing showed that ADAR1 was an important regulator of circRNAs in PH. CircCDK17 level was significantly lowered in the serum of PH patients. The effects of ADAR1 on cell cycle progression and proliferation were mediated by circCDK17. ADAR1 affects the stability of circCDK17 by mediating A-to-I modification at the A5 and A293 sites of circCDK17 to prevent it from m1A modification. We demonstrate for the first time that ADAR1 contributes to the PH development, at least partially, through m1A modification of circCDK17 and the subsequent PASMCs proliferation. Our study provides a novel therapeutic strategy for treatment of PH and the evidence for circCDK17 as a potential novel marker for the diagnosis of this disease.

Objective:To design a modified S1PR3 specific agonist, GPS-725.017, and investigate its protective effect on acute lung injury by promoting macrophage clearance of bacteria.Methods:A short peptide derived from the intracellular region of S1PR3 receptor was named GPS725.017, which was modified with norleucine (Nle) and myristicacid (myr) at its N terminus. Mice were divided into the sham operation group, solvent group and GPS-725.017 treatment group. The acute lung injury model was induced by endotracheal injection of E. coli (5×10 6 CFU), and the experimental group was treated with GPS-725.017 (10 mg/kg). The 48-h survival rate of mice was recorded. After 5 h of modeling, the bacterial load and inflammatory cytokines in peripheral blood and lung were detected, and Vps34 protein content in alveolar macrophages was determined by Western blot. After 12-h of modeling, lung tissues were collected for H&E staining and pathological scores. Results:Compared with the solvent group, the survival rate of mice in the GPS-725.017 treatment group was significantly improved ( P<0.01), the bacterial CFU in blood and alveolar lavage fluid was significantly lower than that in the solvent group ( P<0.001), and the levels of TNF-α and IL-1β in blood and alveolar lavage fluid were significantly lower than those in the solvent group ( P<0.001). Western blot showed that the expression level of Vps34 protein in alveolar macrophages was significantly higher than that in the solvent group ( P<0.01). Histopathology result showed that the pathological damage of lung in the treatment group was significantly less than that in the solvent group ( P<0.001). Conclusions:The modified synthetic S1PR3 specific agonist GPS-725.017 could specifically activate the S1PR3 receptor on the membrane of alveolar macrophages and up-regulate the expression level of intracellular Vps34 protein, which can promote the removal of bacteria in alveolar macrophages, significantly reduce the degree of lung injury and improve the survival rate in ALI mice.
