1.Why anticoagulant studies on sepsis fail frequently --- start with SCARLET.
Chinese Journal of Traumatology 2023;26(5):297-302
The Sepsis Coagulopathy Asahi Recombinant LE Thrombomodulin (SCARLET) trial has many defects, and thus cannot be the terminator of recombinant thrombomodulin (rTM). On the contrary, it provides sufficient evidence for further research. Based on analysis focusing on the failure of SCARLET and several previous anticoagulant studies, it is most important for new studies to grasp the following two points: (1) The enrolled cases should have sufficient disease severity and a clear standard for disseminated intravascular coagulation; (2) Heparin should not be used in combination with the investigated drugs. Multiple post-hoc analyses show that no combination of heparin will not increase the risk of thromboembolism. In fact, the combination of heparin can mask the true efficacy of the investigated drug. Due to the complexity of sepsis treatment and the limitations of clinical studies, the results of all treatment studies should be repeatedly verified, rather than be determined at one stroke. Some research conclusions contrary to disease physiology, pharmacology and clinical practice may be deceptive, and should be cautious rather than be simply accepted. On the other hand, the dissenting voices in the "consensus" scene are often well discussed by the authors and should be highly valued.

Thromboembolism is a crucial part of the global disease burden. It has high incidence, high mortality and disability rates, and the mechanism of occurrence and development is extremely complex. It is difficult to detect the disease in the early stage so that we have trouble with clinical prevention and treatment in general. At present, four items of blood coagulation and D-dimer have been widely used in the evaluation and auxiliary diagnosis of thromboembolism, the monitoring of effect for antithrombotic drugs and other fields. The thrombus biomarkers including thrombin-antithrombin complex (TAT), thrombomodulin (TM), tissue plasminogen activator-inhibitor complex (t-PAIC) and α2-plasmin inhibitor-plasmin complex (PIC) fill the gap of laboratory diagnosis before clinical symptoms appear in some degree. This article aims to explain the current application status of TAT, TM, t-PAIC and PIC in thromboembolism and explore their potential application value, so as to provide a reference for selecting appropriate early monitoring indicators for high-risk population of thromboembolism.

BACKGROUND/AIMS: Recently, recombinant human soluble thrombomodulin (rTM) has been developed as a new drug for disseminated intravascular coagulation (DIC). This study aims to evaluate the clinical benefit of rTM in patients with sepsis-induced DIC caused by acute cholangitis who underwent biliary drainage. METHODS: Patients were divided into two groups: the rTM therapy group and the non-rTM therapy group. The primary outcome was the DIC resolution rate at 7 days, and the secondary outcome was 28-day mortality rate. RESULTS: Thirty-five patients were treated by rTM, and 36 patients were treated without rTM for DIC. The rate of resolution of DIC at day 7 was significantly higher in the rTM group than in the non-rTM group (82.9% vs 55.6%, p=0.0012). Compared with the non-rTM group, the 28-day survival rate of the r-TM group was significantly higher (rTM vs non-rTM, 91.4% vs 69.4%, p=0.014). According to multivariate analysis, non-rTM (hazard ratio [HR], 2.681) and CRP (HR, 2.370) were factors related to decreased survival. CONCLUSIONS: rTM treatment may have a positive impact on improving DIC and survival rates in patients with severe acute cholangitis.

BACKGROUND/AIMS: To identify the risk factors for metachronous gastric neoplasms in patients who underwent an endoscopic resection of a gastric neoplasm. METHODS: We prospectively collected clinicopathologic data and measured the methylation levels of HAND1, THBD, APC, and MOS in the gastric mucosa by methylation-specific real-time polymerase chain reaction in patients who underwent endoscopic resection of gastric neoplasms. RESULTS: A total of 257 patients with gastric neoplasms (113 low-grade dysplasias, 25 high-grade dysplasias, and 119 early gastric cancers) were enrolled. Metachronous gastric neoplasm developed in 7.4% of patients during a mean follow-up of 52 months. The 5-year cumulative incidence of metachronous gastric neoplasm was 4.8%. Multivariate analysis showed that moderate/severe corpus intestinal metaplasia and family history of gastric cancer were independent risk factors for metachronous gastric neoplasm development; the hazard ratios were 4.12 (95% confidence interval [CI], 1.23 to 13.87; p=0.022) and 3.52 (95% CI, 1.09 to 11.40; p=0.036), respectively. The methylation level of MOS was significantly elevated in patients with metachronous gastric neoplasms compared age- and sex-matched patients without metachronous gastric neoplasms (p=0.020). CONCLUSIONS: In patients who underwent endoscopic resection of gastric neoplasms, moderate/severe corpus intestinal metaplasia and a family history of gastric cancer were independent risk factors for metachronous gastric neoplasm, and MOS was significantly hypermethylated in patients with metachronous gastric neoplasms.

BACKGROUND: The pathologic distinction between high-grade prostate adenocarcinoma (PAC) involving the urinary bladder and high-grade urothelial carcinoma (UC) infiltrating the prostate can be difficult. However, making this distinction is clinically important because of the different treatment modalities for these two entities. METHODS: A total of 249 patient cases (PAC, 111 cases; UC, 138 cases) collected between June 1995 and July 2009 at Seoul St. Mary's Hospital were studied. An immunohistochemical evaluation of prostatic markers (prostate-specific antigen [PSA], prostate-specific membrane antigen [PSMA], prostate acid phosphatase [PAP], P501s, NKX3.1, and α-methylacyl coenzyme A racemase [AMACR]) and urothelial markers (CK34βE12, p63, thrombomodulin, S100P, and GATA binding protein 3 [GATA3]) was performed using tissue microarrays from each tumor. RESULTS: The sensitivities of prostatic markers in PAC were 100% for PSA, 83.8% for PSMA, 91.9% for PAP, 93.7% for P501s, 88.3% for NKX 3.1, and 66.7% for AMACR. However, the urothelial markers CK34βE12, p63, thrombomodulin, S100P, and GATA3 were also positive in 1.8%, 0%, 0%, 3.6%, and 0% of PAC, respectively. The sensitivities of urothelial markers in UC were 75.4% for CK34βE12, 73.9% for p63, 45.7% for thrombomodulin, 22.5% for S100P, and 84.8% for GATA3. Conversely, the prostatic markers PSA, PSMA, PAP, P501s, NKX3.1, and AMACR were also positive in 9.4%, 0.7%, 18.8%, 0.7%, 0%, and 8.7% of UCs, respectively. CONCLUSIONS: Prostatic and urothelial markers, including PSA, NKX3.1, p63, thrombomodulin, and GATA3 are very useful for differentiating PAC from UC. The optimal combination of prostatic and urothelial markers could improve the ability to differentiate PAC from UC pathologically.

BACKGROUNDPrevention of osteonecrosis (ON) has seldom been addressed. The purpose of this study was to evaluate the effect of resveratrol on preventing steroid-induced ON in rabbits.
METHODSSeventy-two rabbits were divided into four groups: (1) NEC (ON) group: thirty rabbits were treated with lipopolysaccharide (LPS) once, then with methylprednisolone (MPS) daily for 3 days; (2) PRE (prevention) group: thirty rabbits were given one dose of LPS, then MPS daily for 3 days, and resveratrol on day 0 and daily for 2 weeks; (3) RES (resveratrol) group: six rabbits were given resveratrol for 2 weeks but without LPS/MPS; (4) CON (control) group: six rabbits were given alcohol for 2 weeks but without LPS/MPS. Levels of plasma tissue-type plasminogen activator (t-PA), plasminogen activator inhibitor 1 (PAI-1), thrombomodulin (TM), vascular endothelial growth factor (VEGF), maximum enhancement (ME) by magnetic resonance imaging, and ON incidence were evaluated.
RESULTSThe PRE group had a lower ON incidence than the NEC group, but with no significant differences at 2 weeks and 12 weeks. The RES and CON groups did not develop ON. TM and VEGF were significantly higher in the NEC group compared with the PRE group at weeks 1, 2, and 4 (TM: 1 week, P = 0.029; 2 weeks, P = 0.005; and 4 weeks, P = 0.047; VEGF: 1 week, P = 0.039; 2 weeks, P = 0.021; 4 weeks, P = 0.014), but the difference disappeared at 12 weeks. The levels of t-PA and PAI-1 were not significantly different between the NEC and PRE groups. The TM, t-PA, PAI-1, and VEGF concentrations in the RES and CON groups did not change over time. Compared to the baseline, ME in the NEC group decreased significantly (P = 0.025) at week 1, increased significantly (P = 0.021) at week 2, and was decreased at week 12. The variance was insignificant in the PRE group.
CONCLUSIONSResveratrol may improve blood supply to bone in a rabbit model of ON of the femoral head via anti-inflammatory effects to protect the vascular endothelium and reduce thrombosis.

OBJECTIVEThis study was to detect the plasma thrombomodulin (TM), D-dimer and fibrinogen in patients with multiple myeloma (MM) and to analyze their relationship with morbid state, and also to investigate the relationship of the expression of coagulation factor with the ratio of myeloma cells.
METHODSELISA was used to detect the TM level in 45 cases of MM at different stages. The plasma level of D-dimer and fibrinogen was detected by STA automatic coagulation analyser.
RESULTSThe level of plasma TM in newly diagnosed patients was higer than that in normal control group and in platform stage group (P < 0.01; P < 0.05). There were significant differences between relapsed or refractory group and normal control group or those reached platform stage group (P < 0.05). Meanwhile, the level of plasma TM in the group of thalidomide combined with chemotherapy was higer than that in newly diagnosed patients (P < 0.05). The level of plasma D-dimer and fibrinogen of MM patients was higher than that in normal controls (P < 0.01;P < 0.05). The expression of D-Dimer in relapsed or refractory group reached the maximum. Also, the level of plasma D-Dimer in group of thalidomide combined chemotherapy was higer than in newly diagnosed patients (P < 0.05). The expression of coagulation factor did not correlate with the ratio of myeloma cells.
CONCLUSIONSLevel of plasma TM, D-Dimer and fibrinogen of MM patients is higher than that in control group. The level of plasma TM and D-Dimer can be elevated when thalidomide used, which indirectly suggested the tendency for thrombosis in MM patients.

Upper tract urothelial carcinoma (UTUC), which comprises tumors of the ureter and renal pelvis, is a rare genitourinary malignancy. Among these tumors, transitional cell carcinoma (TCC) of the renal pelvis is highly uncommon, and cutaneous metastasis of this tumor is very rare. Herein, we report a case of cutaneous metastasis of TCC of the renal pelvis, clinically mimicking an abscess. A 79-year-old woman was diagnosed with TCC of the left renal pelvis, and underwent wide nephrectomy and chemotherapy in August 2012. She presented with painful, solitary 3 cm sized erythematous dome-shaped mass on the right lower abdomen that had been present for two weeks. We took biopsies of the center and periphery of the mass. Histopathological findings were consistent with cutaneous metastasis of TCC. Immunohistochemical examination showed strongly positive cytokeratin 7 staining, and negative cytokeratin 20 and thrombomodulin staining.

OBJECTIVETo evaluate the roles of N-terminal lectin-like domain of thrombomodulin (TM-N) and receptor for advanced glycation end products (RAGE) in acute hepatic failure using a mouse model system.
METHODSAcute hepatic failure was induced in Kunming mice by intraperitoneal injection of D-galactosamine (D-Galn at 600 mg/kg) and lipopolysaccharide (LPS at 5 mug/kg) and mice were divided into groups for injection with saline, recombinant (r)TM-N protein, or recombinant soluble (rs)RAGE protein. Unmanipulated model mice served as the negative controls. Effects on liver expression of high mobility group box-1 (HMGB1) were detected by immunohistochemistry and real time RT-PCR. Effects on serum levels of tumor necrosis factor-alpha (TNFa) and interleukin-1 beta (IL)-1b were quantified by ELISA.
RESULTSTreatment with rTM-N and rsRAGE both alleviated the acute liver damage induced by D-Galn/LPS exposure, and decreased the hepatic expression of HMGB1 as well as the serum levels of TNFa and IL-1b.
CONCLUSIONIntraperitoneal delivery of rTM-N and rsRAGE can alleviate acute liver damage by modulating the expression of necrosis- and inflammation-related factors.
