AIM: To investigate the effect of Dendranthema morifolium (Ramat) Tzvel (DM) on isolated rat heart and ventricular myocytes during ischemia/anoxia and reperfusion/reoxygenation.METHODS: The Langendorff perfused rat hearts were used to measure intraventricular pressure and coronary flow. The cell contraction and intracellular calcium transient in enzymatically isolated ventricular myocytes were determined. RESULTS: (1) DM (0.5 g/L) significantly attenuated the inhibitory effects induced by ischemia/reperfusion on left ventricular developed pressure (LVDP), ?dp/dt max, coronary flow and LVDP?HR, meanwhile increased the content of SOD and decreased the content of MDA in the myocardium; (2) DM (0.5 g/L) attenuated the inhibitory effects of anoxia and reoxygenation on [Ca 2+]i transient and cell contraction in isolated ventricular myocytes. CONCLUSION: DM attenuated the effects on contractility and intracellular calcium induced by ischemia/anoxia and reperfusion/reoxygenation in the isolated rat heart and the ventricular myocytes. The mechanism might be related to increase in SOD activity and maintaining [Ca 2+]i homeostasis.

AIM: To study the effect of salvia miltiorrhiza (SM) on cell contraction and intracellular calcium of enzymatically isolated rat ventricular myocytes during normoxia and anoxia/reoxygenation. METHODS: Contraction and intracellular calcium were determined with video tracking system and spectrofluorometric method, and the chemical anoxic method was employed. RESULTS: The ?d L /d t max , dL of cell contraction and the amplitude of [Ca 2+ ] i in the cardiomyocytes following SM treatment were decreased in a dose-dependent manner. During anoxia, the ?d L /d t max , dL and amplitude of [Ca 2+ ] i were decreased, while the diastolic Ca 2+ level was elevated compared with control group. All the contractile parameters and the diastolic Ca 2+ level were back toward pretreatment values during reoxygenation, but could not return to control level. After the treatment with SM (3 g/L), ?d L /d t max and dL of cell contraction and the amplitude of [Ca 2+ ] i were higher and the diastolic Ca 2+ level was lower than those in anoxia/reoxygenation group. CONCLUSION: SM antagonized effects of anoxia and reoxygenation on cell contraction and intracellular calcium in isolated ventricular myocytes.

Swine vesicular disease (SVD) is a highly contagious viral disease that causes vesicular disease in pigs. The importance of the disease is due to its indistinguishable clinical signs from those of foot-and-mouth disease, which prevents international trade of swine and related products. SVD-specific antibody detection via an enzyme-linked immunosorbent assay (ELISA) is the most versatile and commonly used method for SVD surveillance and export certification. Inactivated SVD virus is the commonly used antigen in SVD-related ELISA. A recombinant SVD virus-like particle (VLP) was generated by using a Bac-to-Bac baculovirus expression system. Results of SVD-VLP analyses from electron microscopy, western blotting, immunofluorescent assay, and mass spectrometry showed that the recombinant SVD-VLP morphologically resemble authentic SVD viruses. The SVD-VLP was evaluated as a replacement for inactivated whole SVD virus in competitive and isotype-specific ELISAs for the detection of antibodies against SVD virus. The recombinant SVD-VLP assay produced results similar to those from inactivated whole virus antigen ELISA. The VLP-based ELISA results were comparable to those from the virus neutralization test for antibody detection in pigs experimentally inoculated with SVD virus. Use of the recombinant SVD-VLP is a safe and valuable alternative to using SVD virus antigen in diagnostic assays.

Objective: To evaluate the clinical efficacy of two different digestive tract reconstruction methods in the Siewert Ⅱ or Ⅲ adenocarcinoma of esophagogastric junction underwent proximal gastrectomy and piggyback jejunal interposition. Methods: A total of 84 patients with Siewert Ⅱ or Ⅲ AEG who underwent proximal gastrectomy and interposition jejunal anastomosis were enrolled prospectively according to the exclusion criteria, from October 2015 to August 2017 at Department of Digestive Minimally Invasive Surgery, Shanxi Cancer Hospital. There were 61 male and 23 female patients, aged 48-69 years with an average age of 59.7 years. They were divided into single-tract reconstruction group (n=41) and double-tract reconstruction group (n=43) according to random number table. Both groups underwent proximal gastrectomy and piggyback jejunal interposition. After side-to-side anastomosis of the remnant stomach and jejunum was performed in the single-tract group, jejunum 3 cm below the anastomosis was ligated or closed. The jejunum in the double-tract group was not treated during the operation. Relevant nutritional indicators were collected at 3 months and 6 months after operation. The data were analyzed by repeated measurement of variance analysis to determine the nutritional status. Results: There was no significant difference in preoperative general condition between single-tract reconstruction group and double-tract reconstruction group (P>0.05). There was no significant difference in perioperative related indicators (P>0.05). Nutritional indicators in single-channel reconstruction group were higher than those in double-channel reconstruction group (hemoglobin: F=23.374, P=0.000; albumin: F=6.149, P=0.003; total protein: F=18.362, P=0.000; weight: F=74.255, P=0.000). The quality of life was compared half year after operation, there was no significant difference in the incidence of subjective symptoms such as reflux, heart burning, nausea and vomiting, dysphagia and sternum discomfort in the two groups (P>0.05), as well as the results of QLQ-STO22 score (27.0±3.8 vs. 27.6±3.3, t=-0.688, P=0.494). The results of gastroscopy showed that the incidence and degree of the two groups were almost the same whether in the incidence of reflux esophagitis (2/41 vs. 2/43, P=1) or in the contrast of reflux degree (Z=-1.528, P=0.127). Conclusion For patients with type Siewert Ⅱ or Ⅲ esophagogastric junction adenocarcinoma who underwent proximal gastrectomy and piggyback jejunal operation, single tract reconstruction is ideal.

Background/Aims: To evaluate the causal correlation between complement components and non-viral liver diseases and their potential use as druggable targets. Methods: We conducted Mendelian randomization (MR) to assess the causal role of circulating complements in the risk of non-viral liver diseases. A complement-centric protein interaction network was constructed to explore biological functions and identify potential therapeutic options. Results: In the MR analysis, genetically predicted levels of complement C1q C chain (C1QC) were positively associated with the risk of autoimmune hepatitis (odds ratio 1.125, 95% confidence interval 1.018–1.244), while complement factor H-related protein 5 (CFHR5) was positively associated with the risk of primary sclerosing cholangitis (PSC;1.193, 1.048– 1.357). On the other hand, CFHR1 (0.621, 0.497–0.776) and CFHR2 (0.824, 0.703–0.965) were inversely associated with the risk of alcohol-related cirrhosis. There were also significant inverse associations between C8 gamma chain (C8G) and PSC (0.832, 0.707–0.979), as well as the risk of metabolic dysfunction-associated steatotic liver disease (1.167, 1.036–1.314). Additionally, C1S (0.111, 0.018–0.672), C7 (1.631, 1.190–2.236), and CFHR2 (1.279, 1.059–1.546) were significantly associated with the risk of hepatocellular carcinoma. Proteins from the complement regulatory networks and various liver diseaserelated proteins share common biological processes. Furthermore, potential therapeutic drugs for various liver diseases were identified through drug repurposing based on the complement regulatory network. Conclusions Our study suggests that certain complement components, including C1S, C1QC, CFHR1, CFHR2, CFHR5, C7, and C8G, might play a role in non-viral liver diseases and could be potential targets for drug development.

【Objective】 To evaluate the clinical efficacy and prognostic factors in multiple myeloma (MM) patients treated with autologous hematopoietic stem cell transplantation (auto-HSCT). 【Methods】 The clinical data of 155 MM patients newly diagnosed and suitable for transplantation in our hospital from 2014 to 2021 were retrospectively analyzed. They were divided into auto-HSCT group and non-auto-HSCT group according to the treatment mode. The clinical efficacy, overall survival (OS) and progression-free survival (PFS) of the two groups were compared. Furthermore, the prognostic factors of auto-HSCT group were analyzed. 【Results】 ① There were 51 patients in auto-HSCT group and 104 patients in non-auto-HSCT group. There was no statistical difference in baseline characteristics except age between the two groups. ② Hematopoietic reconstruction was achieved in all patients in auto-HSCT group, and no transplantation-related mortality was found. ③ The clinical efficacy of pre-and post-transplantation was compared in auto-HSCT group. sCR/CR rate was significantly increased after transplantation (P=0.041). The effective remission rate (≥VGPR) was also higher (P=0.05). As for the best efficacy, sCR/CR rate and effective remission rate were both significantly higher in auto-HSCT group than in non-auto-HSCT group (P=0.001). ④ In auto-HSCT group, by the end of follow-up, the median OS was not reached, the median PFS was 30.5 months, and 3-year OS and PFS was 87% and 40.3%, respectively. In non-auto-HSCT group, the median OS was 61 months, the median PFS was 21 months, and 3-year OS and PFS was 65.3% and 33.1%, respectively. It indicated that OS was significantly prolonged in auto-HSCT group (P=0.004). PFS was also prolonged but without significant difference (P=0.065). ⑤ Analysis of prognostic factors in auto-HSCT group showed that decreased PLT (P=0.038) and increased serum-adjusted calcium (P=0.017) were independent risk factors for OS, decreased PLT (P=0.005), female (P=0.018) and disease status of PR or worse before transplantation (P=0.012) were independent risk factors for PFS. 【Conclusion】 Auto-HSCT can improve the remission rate, prolong OS in MM patients, and possibly prolong PFS. Increased serum-corrected calcium and decreased PLT are independent prognostic factors for OS in patients treated with auto-HSCT. Decreased PLT, female, and disease status of PR or worse before transplantation are independent prognostic factors for PFS.
