ABSTRACT

@#Objective    To investigate whether metformin has protective effect on myocardial injury in patients with coronavirus disease 2019 (COVID-19) combined with coronary heart diseases and diabetes. Methods    COVID-19 patients with coronary heart disease and diabetes who were admitted to Tongji Hospital from January 18 to April 25 in 2020 were enrolled. They were divided into a metformin group and a none-metformin group according to whether the metformin was used. The demographic characteristics, clinical symptoms, laboratory parameters, treatment and clinical outcomes of the two groups were analyzed retrospectively. Results    There were 29 patients in the metformin group, 3 patients (12.0%, 3/25) suffered myocardial injury and 1 (3.4%) died of acute respiratory failure complicated by septic shock; 67 patients were in the non-metformin group and 24 (37.5%, 24/64) had myocardial injury but 15 died in hospital among whom 1 died of septic shock complicated by disseminated intravascular coagulation, 1 acute respiratory failure complicated by possible cerebral hemorrhage, 2 acute respiratory failure, 1 fulminant myocarditis, 3 acute myocardial infarction and 7 cardiac arrest. The incidence of myocardial injury (12.0% vs. 37.5%, P=0.019), hospital mortality (3.4% vs. 22.4%, P=0.034) and mortality of cardiovascular events (0.0% vs. 16.4%, P=0.049) in the metformin group were significantly lower than those in the non-metformin group. Multivariate analysis showed that the use of insulins (OR=11.235, P=0.003) was an influencing factor for in-hospital mortality of patients. The use of metformin (OR=0.154, P=0.013) was positively correlated with the myocardial injury. Conclusion    When patients with coronary heart disease and diabetes are infected with COVID-19, metformin can effectively reduce myocardial damage and has a certain effect on reducing hospital mortality. Combined with clinical considerations, it is worthy of popularization.

ABSTRACT

Objective@#To evaluate the clinical effectiveness of combining electrical stimulation with manual massage in treating women′s myofascial pelvic pain (MPPS).@*Methods@#A total of 93 MPPS patients were recruited and randomly divided into an infrared irradiation group (n=30), an electrical stimulation group (n=31) and a combination group (n=32). Those in the infrared group and the electrical stimulation group were given 30 minutes of infrared irradiation or electrical stimulation daily for 10 days, while the combined group was given a manual massage with electrical stimulation. The response to treatment was evaluated using a visual analogue scale (VAS) to rate discomfort, plus a physical examination, and surface electromyography results using Glazer′s protocol. The treatments′ efficacy and the recurrence of pain were evaluated 1 month after the treatment.@*Results@#The average VAS ratings, resting potentials and their variability of the three groups all improved significantly after the treatment. The average VAS scores of the combined and electrical stimulation groups after the treatment were significantly lower than that of the infrared group. Moreover, the total effective rates of the combined group (96.87%) and the electrical stimulation group (80.65%) were significantly higher than that of the infrared group (56.67%), and the resting potential and variability of the former two groups were also significantly better. All of the above measurements among the combined group after the treatment were significantly better, on average, than in the electrical stimulation group. A month later the recurrence rate in the combined group (6.25%) was significantly lower than in the electrical stimulation group (25.81%) and the infrared group (56.67%).@*Conclusion@#Electrical stimulation combined with manual massage is effective in relieving myofascial pelvic pain.

ABSTRACT

Epidemiology studies have demonstrated inconsistent associations between type 2 diabetes mellitus and the risk of malignant melanoma. To this end, the aim was to perform a meta-analysis of cohort studies. Medline, PubMed, Embase and the Cochrane Library were searched up to February 2014. Cohort studies addressing the relative risk of type 2 diabetes mellitus on malignant melanoma were included in this meta-analysis. The Newcastle-Ottawa Scale was applied for quality evaluation. The pooled relative risks with the corresponding 95% confidence intervals [95% CIs] were calculated by using random-effects or random-effects model. Heterogeneity and publication bias were evaluated by I[2] and funnel plot analysis, respectively. Data was analyzed using STATA 11.0. A total of 9 independent cohorts from 8 manuscripts were entered this meta-analysis. Type 2 diabetes mellitus was slightly associated with an increased risk of malignant melanoma, and the pooled relative risk was 1.15 [95% CI, 1.00-1.32] in diabetes compared with non-diabetes with significant evidence of heterogeneity among these studies [P=0.016, I[2] =57.6%]. For the studies adjusted for age, gender and obesity, the relative risks were 1.21[95% CI, 1.03-1.42], 1.17 [95% CI, 1.01-1.35] and 1.11 [95% CI, 1.00-1.24], respectively. For the population-based studies in which case cohort established, the relative risk was 1.85 [95% CI, 1.31-2.62]. Type 2 diabetes might be an independent risk factor for malignant melanoma. Further studies are needed to specifically test the effect, and fully elucidate the underlying pathophysiologic mechanisms

ABSTRACT

Objective: To study the influences of Tiaozhixin(TZX) on NO/ET, 6 keto PGF 1a /TXB 2 and hemorrheology rats with hyperlipoidemia. Methods: The rat hyperlipoidemia and early atheroscleorsis models were established by feeding high lipid diet for 40 days. Meanwhile TZX was taken by oral administration at the dosages of 40、80g/kg. The levels of NO、ET 1、6 keto PGF 1a and TXB 2 in serum were determind, and the hemorrheology markers were observed. Results: TZX could raise the levels of NO in serumobviourly ET 1 level of the normal and model rats. The large dose of TZX could increase 6 keto PGF 1a content remarkably which benefits maintenance of the balances of 6 keto PGF 1a /TXB 2. It could lower the whole blood specific viscosity, whole blood reduction specific viscosity, plasma specific viscosity; aggregation index of RBC; shorten RBC electrophoresis time; also decrease fibrinogen content; inhibit the platelet aggregation of normal rats induced by ADP. Conclusion: TZX can improve the abnormal hemorrheology and recover the balance of TXB 2/6 keto PGF 1a and NO/ET of rats with hyperlipoidemia, which might be one of mechanisms of antiatherosclerosis action.

ABSTRACT

The effects of TSCP and TSCC on aggregation and adhesion of blood platelets were measured by turbidimetric method and salzman method respectively. TSCP and TSCC strongly increase mouse and rat platelet aggregation and platelet adhesion. These effects are important for blood coagulation. cAMP and TXB2 levels in plasma and platelet were determind by RIA TSCP significantly increased the TXB2 level in plasma and platelet. This effect may be the main mechanism of increasing platelet aggregation by TSCP.

ABSTRACT

The anti-inflammatory of waterand fat-soluble alkoloids of Leon-tice Kiagnanensis (WSALK, FSALK ) were described after sc of WSALK (150, 300 mg/kg ) and FSALK (13, 26mg/kg ) . The increased capillary permeability in abdominal cavity and skin of mice induced respectively by 0.7% HAc and histamin were inhibited abviously. WSALK (75, 150, 300mg/kg, ip ) and FSALK (6.5, 13, 26mg/Kg, ip ) markedly inhibited the ear inflammation induced by xylene in mice, carrageenin-iaduces swelling of the ankle in normal on adrenalecto-mized rats, and carrageenin-induced pleurisy in rats. Both compound also inhibited the granuloma induced by cotton pellet after sc of WSALK 300, 600 mg/kg and FSALK 13, 26 mg/kg qd ? 7d.Both compound decreased the content of PGE in exudate formed after injecting carrageenin into the hind paw of rats. These results suggest that both compounds passesses the anti-inflammatory activity and their actions might be relatied to their inhibiting the synthesis or relase of pro-staglandin E. WSALK TI 9.35, FSALK TI 4.50.
