Path analysis of the influence of social support and ruminant meditation on post-traumatic growth of pulmonary tuberculosis patients / 中国实用护理杂志

Objective:To explore the path and relationship between social support and ruminant meditation of tuberculosis patients on their post-traumatic growth (PTG).Methods:A total of 156 patients treated from January 2018 to August 2019 were selected as the research objects. The social support rating scale, event-related ruminant meditation questionnaire, and post-traumatic growth rating scale were used for investigation and analysis, and 150 valid questionnaires were obtained. The path analysis method was used to analyze the mutual influence between people.Results:The patient ′s post-traumatic growth, social support and ruminant meditation scores were (62.71±12.28), (38.19±9.79) and (27.28±11.18) points, respectively; social support and purposeful ruminant meditation directly affected tuberculosis patient's PTG (effect value was 0.57); social support indirectly positively affected the patient's PTG through purposeful ruminant meditation (indirect value was 0.77), and purposeful ruminant meditation was the mediating variable. Conclusion:The PTG, ruminant contemplation level and social support of pulmonary tuberculosis patients need to be improved. Social support can directly and indirectly affect the PTG level of pulmonary tuberculosis patients.

Safety and efficacy of ultrafiltration on heart failure patients with reduced ejection fraction and diuretic resistance: results from a single-center randomized controlled trial / 中华心血管病杂志

Objective: To investigate the safety and efficacy of ultrafiltration on diuretic sensitivity in heart failure patients with reduced ejection fraction and diuretic resistance. Methods: This was a single-center randomized controlled trial. A total of 148 heart failure patients with reduced ejection fraction admitted to the Hospital of Traditional Chinese Medicine of Xinjiang Uygur Autonomous Region from June 2010 to June 2020 were enrolled in this study, and these patients were randomly divided (ratio 1:1) into the ultrafiltration group (n=74) and the control group (n=74). All patients were treated with diuretics, cardiotonic, vasodilator and other comprehensive drugs according to relevant guidelines. After grouping, the patients in the control group were treated with standard treatment plan, while patients in the ultrafiltration group were treated with ultrafiltration on top of standard therapy. Diuretic drugs were discontinued during ultrafiltration, and intravenously furosemide (40 mg) was given immediately and 24 hours after the end of ultrafiltration. Clinical data including gender, age, complicated diseases, New York Heart Association (NYHA) function classification, etc. were collected. Effectiveness indicators include urine volume (the first 12-hour and 24-hour urine volume and the second 24-hour urine volume after using diuretic), body weight and dyspnea severity score. Safety indicators include systolic blood pressure, serum creatinine, serum Na+ concentration, blood K+ concentration and the number of deaths before and after intervention. Results: Two patients in the control group died due to worsening heart failure after randomization and were excluded in this study, 146 patients were finally analyzed (72 patients in the control group and 74 patients in the ultrafiltration group). There were 93 males, and the age was (68.3±11.2) years. There was no significant difference between patients in the ultrafiltration group and the control group in gender, age, body weight, course of disease, dyspnea severity score, NYHA function classification Ⅲ/Ⅳ, the proportion of patients with severe edema of both lower limbs, the proportion of patients with complicated diseases, and basic medication (all P>0.05). After using diuretics, the urine volume of the first 12-hour and 24-hour and the second 24-hour were significantly higher in the ultrafiltration group than in the control group (all P<0.05). Body weight decreased significantly after ultrafiltration treatment as compared with that before intervention in the ultrafiltration group (P<0.05). Compared with the control group, the dyspnea severity score was significantly improved in the ultrafiltration group (P<0.05). There was no significant difference in systolic blood pressure, serum creatinine, serum Na+ concentration, blood K+ concentration of patients between ultrafiltration group and control group before and after intervention (all P>0.05). During the clinical diagnosis and treatment, 2 male patients in the control group died, and the cause of death was aggravation of basic diseases complicated with acute heart failure and cardiogenic shock. There was no death in the ultrafiltration group, and there were no obvious clinical adverse events during and after ultrafiltration. Conclusion: Ultrafiltration therapy is safe and can improve diuretic sensitivity in heart failure patients with reduced ejection fraction and diuretic resistance.

Effect of Xihuangwan on NLRP3 Inflammatory Bodies and Their Products and Tumor Proliferation of Lung Cancer A549 Bearing Nude Mice in Inflammatory Microenvironment / 中国实验方剂学杂志

Objective:To study the antitumor effect of Xihuangwan on A549 lung cancer nude mice in inflammatory microenvironment, and explore the effect of Xihuangwan on the expressions of nucleotide-binding oligomerization domain-like receptor protein 3 (NLRP3) inflammatory bodies and their products in serum and tumor tissue of A549 lung cancer nude mice. Method:The lung cancer A549 cell model was established in nude mice with lung cancer, and the lung cancer A549 cell model was established in inflammatory microenvironment by adding lipopolysaccharide (LPS) + adenosine triphosphate (ATP) to the culture medium. After modeling, the rats were randomly divided into blank group (equal volume of normal saline), positive drug control group (MCC950 solution, 0.79 g·kg-1), and low, medium, high-dose Xihuangwan groups (0.39, 0.78, 1.95 g·kg-1). The rats were administered orally once a day for 21 days, and then sacrificed. The tumor tissues were stripped to measure the tumor body. The expressions of NLRP3, malondialdehyde（MDA）, interleukin (IL)-1β, IL-18 and NLRP3 were detected by Western blot, and the levels of IL-1β, IL-18 and MDA were detected by enzyme linked immunosorbent assay（ELISA）. Result:Compared with the blank group, the tumor inhibition rates in the positive drug control group and the low, medium and high dose Xihuangwan group were 39.21%, 31.72%, 42.24% and 55.68%. ELISA showed that the high-dose Xihuangwan group could significantly reduce the expressions of MDA, IL-1β and IL-18 in the serum of nude mice (P<0.05). Western blot showed that the high-dose Xihuangwan group could effectively reduce the protein expressions of MDA, IL-1β, IL-18 and NLRP3 in tumor of nude mice (P<0.05), the results of immunohistochemistry showed that the expression rate of NLRP3 in the tumor tissues of nude mice was reduced in the positive drug group and each dose of Xihuangwan group (P<0.05). Conclusion:Xihuangwan can inhibit the growth of tumor tissue of A549 cells bearing lung cancer in nude mice. The mechanism may be that it can inhibit the growth of tumor cells by inhibiting the expression of NLRP3 inflammatory bodies, IL-1β, IL-18, MDA tables, and then inhibiting the inflammatory microenvironment of tumor cells.

ObjectiveTo investigate the clinical effect of Fuhe Beihua prescription combined with transcatheter arterial chemoembolization (TACE) in the treatment of primary liver cancer patients with liver depression and spleen deficiency and its effect on T lymphocyte subsets. MethodsA retrospective analysis was performed for the clinical data of stage Ⅲ primary liver cancer patients with liver depression and spleen deficiency who were treated in Department of Hepatology and Department of Oncology in The First Affiliated Hospital of Guangxi University of Chinese Medicine from January 2018 to January 2020. According to whether the traditional Chinese medicine Fuhe Beihua prescription was used, the patients were divided into treatment group (treated with routine TACE and oral administration of Fuhe Beihua prescription) and control group (treated with routine TACE alone), and the course of treatment was 16 weeks for both groups. The two groups were compared in terms of short-term response rate, quality-of-life score, serum alpha-fetoprotein (AFP) level, four indicators of liver fibrosis, coagulation function parameters, peripheral blood T lymphocyte subsets, and liver function parameters. The independent samples t-test was used for comparison of continuous data between two groups, and the chi-square test was used for comparison of categorical data between two groups. A repeated-measures analysis of variance was used for comparison of continuous data between different groups at different time points. ResultsA total of 218 patients were selected, with 118 in the control group and 100 in the treatment group. The treatment group had an objective response rate of 33% and a disease control rate of 66% at week 8 of treatment and an objective response rate of 34% and a disease control rate of 69% at week 16 of treatment, and the control group had an objective response rate of 26.27% and a disease control rate of 68.64% at week 8 of treatment and an objective response rate of 30.51% and a disease control rate of 68.64% at week 16 of treatment; there was a significant difference in objective response rate between the two groups at weeks 8 and 16 of treatment (P＜0.05). Both groups had significant increases in Karnofsky Performance Scale (KPS) score, fibrinogen, and albumin (Alb) from before treatment to weeks 8 and 16 of treatment (all P＜0.05), and there were significant differences in KPS score, fibrinogen, and Alb between the two groups at weeks 8 and 16 of treatment (all P＜0.05). Both groups had significant reductions in AFP, the four indicators of liver fibrosis, alanine aminotransferase (ALT), aspartate aminotransferase (AST), prothrombin time (PT), and traditional Chinese medicine (TCM) syndrome score after treatment (all P＜0.05), and at weeks 8 and 16 of treatment, there were significant differences between the two groups in AFP, the four indicators of liver fibrosis, ALT, AST, PT, and TCM syndrome score (all P＜0.05). At weeks 8 and 16 of treatment, the treatment group had significant increases in the levels of CD3+, CD4+, and CD4+/CD8+ (all P＜0.05) and a significant reduction in the level of CD8+ (P＜0.05), and there were significant differences in the levels of T lymphocyte subsets between the two groups at weeks 8 and 16 of treatment (all P＜0.05). ConclusionFuhe Beihua prescription combined with routine TACE has a better clinical effect than TACE alone in the treatment of primary liver cancer patients with liver depression and spleen deficiency, possibly by regulating the levels of T lymphocyte subsets.

Enhanced expression of the decoy receptor IL-13Ralpha2 in macrophages of Schistosoma japonicum-infected mice / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Type 2 cytokine interleukin (IL)-13 and its decoy receptor, IL-13 receptor (R) alpha2 appear to play a major role in tissue fibrosis of schistosomiasis and asthma. IL-13 is a key regulator of the extracellular matrix (ECM). It is known to signal to cells by binding to the IL-13Ralpha1, which then heterodimerizes with IL-4Ralpha. In contrast, IL-13Ralpha2 binds IL-13 with high affinity but does not signal. IL-13Ralpha2 is known to down-regulate granulomatous inflammation and prolong host survival in Schistosoma mansoni (S. mansoni) infection, but little is known about the location and expression level of IL-13Ralpha2 in the context of S. japonicum infection.</p><p><b>METHODS</b>We established S. japonicum-infected mouse models. Kinetic serum levels of IL-13Ralpha2 were examined with ELISA. IL-13Ralpha2 mRNA and protein of liver tissues were determined by PCR and immunoblotting analysis, respectively. Detection of IL-13Ralpha2 expression and location in macrophages was performed by TaqMan PCR and fluorescent immunocytochemistry technique, respectively.</p><p><b>RESULTS</b>A marked elevation of mRNA and protein expression of IL-13Ralpha2 was observed in mice during S. japonicum infection. An enhanced expression of IL-13Ralpha2 was further demonstrated in primary macrophages of murine schistosomiasis.</p><p><b>CONCLUSIONS</b>IL-13Ralpha2 in macrophages may be a critical contributor to pathogenesis of schistosomiasis. The data highlight the potential importance of cell signaling and antifibrotic gene therapeutics in T helper 2 cell (Th2)-mediated diseases.</p>

Retrospection and recent advances in fluid resuscitation during burn shock stage / 中华烧伤杂志

To retrospect the development of fluid resuscitation for burn shock and to look to the future. The main achievements in burn care in the past fifty years and existing problems are summarized, and the appropriate regime of fluid resuscitation for burn shock is suggested. Numerous achievements in burn care have been made, including the estimation of burn area, fluid replenishment formula, delayed resuscitation, fluid resuscitation for burn shock complicated by inhalation injury, covert compensatory shock and research on mechanism of burn shock etc. We had established and improved fluid resuscitation formula, and we had made clear how to properly resuscitate burn shock. However how to tide over the patient form burn shock smoothly had not yet reached a consensus. Effective treatment to alleviate hypoxic injuries as a result of severe shock had not been properly defined. Although significant achievements in fluid resuscitation for burn shock have been made, there is still a long way to go to attain a perfect regime. Therefore it is still utterly necessary to carry on in-depth research on this problem both in the laboratory and bedside.
