Effectiveness of shengxuexiaoban capsules combined with glucocorticoid therapy for immune thrombocytopenia: A meta-analysis.

OBJECTIVE: To evaluate the effectiveness of the Shengxuexiaoban Capsules combined with glucocorticoid therapy for immune thrombocytopenia (ITP). METHODS: We collected randomized controlled trials (RCTs) using shengxuexiaoban capsules in combination with glucocorticoid to treat ITP by searching major Chinese and English electronic databases. The outcome indicators were the effective rate, recurrence rate, the number of platelets in the blood, recovery time of platelets, and adverse reactions. We used STATA 16.0 and RevMan 5.3 for meta-analysis and GRADE pro. for evidence quality evaluation. RESULTS: A total of 27 RCTs were included in the meta-analysis, and the results showed a significant difference (all p<0.05) in the effective rate, recurrence rate, the number of platelets, and the recovery time of platelets (≥ 100×109) between ITP patients in the control group (who received glucocorticoid therapy alone) and test group (who received glucocorticoid therapy combined with the Shengxuexiaoban Capsules). And that Shengxuexiaoban capsules combined with glucocorticoid therapy were safe. The funnel plot and Egger's test results indicated no obvious publication bias. The GRADE evidence rating showed an intermediate quality of evidence rating for recurrence rate and overall effectiveness. CONCLUSION: Glucocorticoid therapy combined with the Shengxuexiaoban Capsules showed more effectiveness in the treatment of ITP. It can improve the effective rate, reduce the recurrence rate, increase the number of platelets and shorten the recovery time of platelets, and has a good safety profile.

The Therapeutic Effects of Oral Intake of Hydrogen Rich Water on Cutaneous Wound Healing in Dogs.

This study explored the effects of drinking Hydrogen-rich water (HRW) on skin wound healing in dogs. Eight circular wounds were analyzed in each dog. The experimental group was treated with HRW thrice daily, while the control group was provided with distilled water (DW). The wound tissues of dogs were examined histopathologically. The fibroblasts, inflammatory cell infiltration, the average number of new blood vessels, and the level of malondialdehyde (MDA) and superoxide dismutase (SOD) activity in the skin homogenate of the wound was measured using the corresponding kits. The expressions of Nrf-2, HO-1, NQO-1, VEGF, and PDGF were measured using the real-time fluorescence quantitative method. We observed that HRW wounds showed an increased rate of wound healing, and a faster average healing time compared with DW. Histopathology showed that in the HRW group, the average thickness of the epidermis was significantly lower than the DW group. The average number of blood vessels in the HRW group was higher than the DW group. The MDA levels were higher in the DW group than in the HRW group, but the SOD levels were higher in the HRW group than in the DW group. The results of qRT-PCR showed that the expression of each gene was significantly different between the two groups. HRW treatment promoted skin wound healing in dogs, accelerated wound epithelization, reduced inflammatory reaction, stimulated the expression of cytokines related to wound healing, and shortened wound healing time.

Predictors of Cognitive Impairment After Stroke: A Prospective Stroke Cohort Study.

BACKGROUND: Post-stroke cognitive impairment (PSCI) significantly affects stroke survivors' quality of life and rehabilitation. A risk model identifying cognitive decline at admission would help to improve early detection and management of post-stroke patients. OBJECTIVE: To develop a new clinical risk score for ischemic stroke survivors in predicting 6-12 months PSCI. METHODS: We prospectively enrolled 179 patients diagnosed with acute ischemic stroke within a 7-day onset. Data were analyzed based on baseline demographics, clinical risk factors, and radiological parameters. Logistic regression and area under the receiver operating curve (AUROC) were used to evaluate model efficiency. RESULTS: One hundred forty-five subjects completed a 6-12-month follow-up visit, and 77 patients (53.1%) were diagnosed with PSCI. Age (ß= 0.065, OR = 1.067, 95% CI = 1.016-1.120), years of education (ß= -0.346, OR = 0.707, 95% CI = 0.607-0.824), periventricular hyperintensity grading (ß= 1.253, OR = 3.501, 95% CI = 1.652-7.417), diabetes mellitus (ß= 1.762, OR = 5.825, 95% CI = 2.068-16.412), and the number of acute nonlacunar infarcts (ß= 0.569, OR = 1.766, 95% CI = 1.243-2.510) were independently associated with 6-12 month PSCI, constituting a model with optimal predictive efficiency (AUC = 0.884, 95% CI = 0.832-0.935). CONCLUSIONS: The optimized risk model was effective in screening stroke survivors at high risk of developing 6-12 months PSCI in a simple and pragmatic way. It could be a potential tool to identify patients with a high risk of PSCI at an early stage in clinical practice after further independent external cohort validation.

[Effects of prenatal maternal cold stress on spontaneous, exploratory and anxious behaviors in offspring].

OBJECTIVE: To study the effects of prenatal cold stress on the behavior and mood of offspring in pregnant rats. METHODS: Six SPF-class Wister pregnant rats were randomly divided into normal temperature control group and cold stress group with 3 rats in each group. The pregnant female rats in the normal temperature control group were kept in the environment of (22 ±2)℃, and the pregnant female rats in the cold stress group were placed in the artificial intelligence climate chamber at(4 ±0.1)℃ for 7 days before the birth, and the young rats were divided into normal temperature after the young rats were born. After the young rats were born, they were divided into normal temperature control group of male rats (MR, 22), normal temperature control group of mother rats (FR, 15), cold stress group of male rats (MC, 15), and cold stress group of female rats (FC, 15) .In the fourth generation of the offspring, the open field experiment and the elevated cross maze test were carried out. RESULTS: In the open field experiment, there was no significant difference in spontaneous activity and exploration behavior between the normal temperature control group and the cold stress group (P＞0.05). In the elevated plus maze experiment, the retention time of the open arms, the number of open arms and the distance of the male and female rats in the cold stress group were significantly higher than those in the normal temperature control group (P＜0.05). CONCLUSION: Prenatal maternal cold stress has no significant effect on spontaneous activity, exploration behavior and activity level of offspring, but the offspring have obvious abnormal behaviors with reduced anxiety behavior.
