Objective: The purpose of this study is to provide high-quality evidence to support the effectiveness of the traditional Chinese hot and humid compress in the treatment of LDH with qi stagnation and blood stasis. Methods: From October 2021 to November 2023, 86 patients with LDH of qi stagnation and blood stasis type were recruited in our hospital and divided into a control (n = 43) and an observation group (n = 43) according to the random number table method. The control group was given routine clinical treatment, and the observation group was treated with the hot and humid compress therapy for two weeks. The visual analogue scale (VAS) score, Japanese Orthopaedic Association (JOA) score, TCM syndrome score, serum interleukin-6 (IL-6), serum interleukin-1β (IL-1β), and tumor necrosis factor-α (TNF-α) were observed and compared between the two groups before and after treatment, and the clinical efficacy of the two groups was evaluated. Results: After treatment, the VAS score, TCM symptom score, and serum IL-6, IL-1β, and TNF-α levels decreased in both groups (P P P P P Conclusions: The hot and humid compress of traditional Chinese medicine can effectively relieve pain, restore lumbar function, improve TCM syndromes, reduce the level of inflammatory factors, and have a curative effect in treating LDH.展开更多

This research is a pretest-posttest quasi-experimental study design with a nonequivalent control group. The research sample comprises 24 bully children who were purposefully selected from among the students who had responded positively to the researcher’s call. The participants were randomly assigned into two experimental and control groups. Group therapy intervention was conducted on the experimental group during ten sessions. The tools applied in this study consisted of Cognitive Emotion Regulation Questionnaire by Garnefski et al., State-Trait Anger Expression Inventory by Spielberger and Bullying Scale by Illinois, Espelage and Holt and the subjects answered to their questions in the stage of pretest and posttest. In this research, the data was analyzed based on the analysis of covariance test and with the aid of SPSS software. The findings demonstrated that dialectical behavior therapy has a significant impact on clinical symptoms, anger control and its components and emotional regulation and its components (P < 0.01).展开更多

METHODS: The medical records of 96 patients with acute heart failure were randomly divided into 2 groups(48 cases in observation group and 48 cases in control group). The control group was treated with conventional western medicine, and the observation group was treated with Tanshinone IIA sulfonic acid natrium on the basis of western medicine. The traditional Chinese medicine(TCM) syndromes scores before and after treatment(after 28 d of treatment), clinical efficacy, and cardiac echocardiographic indexes and serum biochemical indicators before and after treatment were observed in the 2 groups. RESULTS: After treatment, the scores of TCM syndromes in the 2 groups were significantly decreased(P < 0.05), and the change in observation group was significantly greater than that in control group(P < 0.05). The total clinical effective rate in observation group was significantly higher than that in control group(91.67% vs 75.00%)(P < 0.05). After treatment, the echocardiographic indexes of left ventricular end-diastolic diameter(LVEDD) and left ventricular end-systolic diameter(LVESD) values were significantly reduced in the 2 groups while the left ventricular ejection fraction(LVEF) and stroke volume(SV) value were significantly increased, and the changes in observation group were significantly larger than those in control group(P < 0.05). After treatment, the levels of serum nuclear factor-kappaB(NF-KB), interleukin-1β(IL-1β) and N-terminal pro-brain natriuretic peptide(NT-proBNP) were significantly decreased in the 2 groups(P < 0.05), while the 6-keto-prostaglandin F1α(6-ketoPGF1α) level was significantly increased. And the changes in observation group were significantly greater than those in control group(P < 0.05). CONCLUSION: Tanshinone combined with western medicine can significantly improve the clinical symptoms of patients with acute heart failure, improve cardiac function, reduce the myocardial damage degree, and effectively reduce the risk of short-term recurrence and death, and it has exact clinical efficacy.展开更多

H...Background: With the appearance of the SARS-CoV-2 Omicron variant the high rate of vaccination breakthroughs showed that current vaccines against COVID-19 can no longer provide adequate protection against infection. However, it is still assumed that vaccination might have a positive effect on the course of the disease. In Germany, general practitioners and specialists are usually the first treatment providers for acute illnesses. In addition, patients with infections of the upper respiratory tract often primarily consult an ear, nose and throat specialist. Most of the Omicron-infected people have a mild course of the disease and, if necessary, receive medical care on an outpatient basis. Little is known about the effectiveness of corona vaccinations on Omicron infections in relation to the clinical symptoms. In our outpatient office, we recorded a sharp increase of corona positive Omicron-infections in the beginning of 2022, despite of vaccinations against COVID-19. In a retrospective analysis, we evaluated the data of our SARS-CoV-2 tested patients with regard to clinical symptoms reported and vaccination status. The focus was particularly on the question to what extent the vaccination status in the case of Omicron infections influences the symptoms of the disease. Methods: We retrospectively evaluated the data of all patients in the first quarter of 2022 who were suspected for COVID-19. At that time, the Omicron variant was dominant in Germany. Clinical symptoms, cycle threshold (Ct) values, and the vaccination status were recorded. Symptomatic patients who tested negative for SARS-CoV-2 served as a control group. Results: Of the total cohort (n = 353), 241 (68%) patients were tested SARS-CoV-2 positive. The symptoms of the corona-positive patients were essentially similar to those of a mild to moderate cold, but compared to SARS-CoV-2-negative patients (n = 69) with a clear shift in favor of fever (35% versus 16%), cough (76% versus 52%) and increased feeling of illness (59% versus 43%), respectively. Ct values revealed no difference between unvaccinated (mean 19.15;SD 3.52) and vaccinated cases (mean 18.15;SD 3.87;p = 0.272). There was no significant correlation between the vaccination status and clinical symptom score in different age groups (age 12 to 17, r (28) = 0.26, p = 0.26;age > 18 to 60, r (191) = 0.06, p = 0.378). Conclusions: According to our results with infections with the Omicron variant, there were no differences between unvaccinated and vaccinated patients concerning clinical symptoms or potential infectivity, especially in children and adolescents. This might have impact on further vaccination programs.展开更多
