Meta-Analysis
BACKGROUND
Intra-uterine infusion treatments were reported to be beneficial to embryo implantation and pregnancy outcomes, and considered as potential therapies for infertile patients with recurrent implantation failure (RIF). Nevertheless, their efficiencies were controversial and there lack of consensus on which intrauterine treatment is the most effective.
METHODS
All prospective trials (in Chinese or English) were searched in Databases PubMed, Cochrane, Web of Science, and CNKI from July 2013 to July 2023. We included studies that investigated various uterine infusions, including chorionic gonadotropin, granulocyte colony-stimulating factor, monocytes, platelet-rich plasma, etc. during IVF treatment and reported subsequent pregnancy outcomes.
RESULTS
We finally included 56 researches, including 40 randomized controlled trials, 14 non-randomized controlled trials, and 3 prospective cohort studies. This study included a total of 11 uterine perfusion methods: Placebo, Human Chorionic Gonadotropin (HCG), Granulocyte Colony-Stimulating Factor (G-CSF), platelet-rich plasma (PRP), Peripheral Blood Mononuclear Cell (PBMC), Growth hormone (GH), dexamethasone (DEX), Embryo culture supernatant (ESC), PRP combined with G-CSF (PRP + G-CSF), RPR combined with subcutaneous injection of G-CSF (RPR + G-CSFsc), G-CSF combined with subcutaneous injection of AXaIU (G-CSF + AXaIUsc). Intrauterine infusion of HCG, PBMC, G-CSF, and PRP significantly improves pregnancy outcomes in patients with repeated implantation failure compared with blank controls or placebo, and PRP improved the clinical pregnancy and live birth most. GH and ESC infusion might improve the pregnancy outcomes, but uterine infusion of DEX was shown with high miscarriage. The combination therapy did not show a significant advantage over the mono-therapy.
CONCLUSIONS
Intrauterine infusion of HCG, PBMC, G-CSF, and PRP are promising strategies for improving pregnancy outcomes for infertile patients with recurrent implantation failure. Among these treatments, PRP may be the best. More researches are required to explore the effect of drug combinations and less commonly used drugs as well.
TRIAL REGISTRATION
Our study was registered in PROSPERO and the ID was CRD42023467188.

Meta-Analysis
BACKGROUND
As the population ages, the prevalence of cerebral small vessel disease (CSVD) steadily increases, resulting in a significant economic burden on society. In East Asian nations, Chinese medicine has been used extensively to teat CSVD and has been reported to improve the cognitive function of patients. The present study aimed to comprehensively assess the efficacy and safety of Chinese medicine as adjuvant therapy for CSVD.
METHODS
A literature search of the CNKI, Wanfang, VIP, SinoMed, Medline, Cochrane Library, and ChiCTR databases were searched for RCTs investigating the use of TCM as an adjuvant in the treatment of CSVD, published up to July 27, 2023, was performed. Based on the Cochrane Collaboration Network bias risk assessment criteria, Review Manager version 5.3 was used to perform a meta-analysis.
RESULTS
Meta-analysis of 27 RCTs, including 2554 subjects, revealed that the majority of the RCTs exhibited risk for ambiguous bias. The findings demonstrated that the use of Chinese medicine as an adjuvant treatment for CSVD effectively enhanced the cognitive function, as evidenced by improvements in the MMSE score (mean difference (MD) = 2.42, 95% confidence interval (CI) [1.79,3.17], P < .00001), MoCA score (MD = 2.39, 95% CI [1.78,2.99], P < .00001) and ADL score (MD = 4.13, 95% CI [1.74,6.51], P = .0007). Furthermore, the study also demonstrated the advantages of Chinese medicine adjuvant therapy in enhancing the Chinese medicine syndrome score (MD = -2.57, 95% CI [-3.31, -1.83], P < .00001), CRP (MD = -1.35, 95% CI [-2.27, -0.43], P = .004), Hcy (MD = -3.44,95% CI [-4.05, -2.83], P < .00001), and blood flow velocity (CBV) (MD = 1.37,95% CI [0.24,2.50], P = .02). Moreover, there was no statistical difference in the incidence of adverse reactions between the 2 groups.
CONCLUSION
Findings of the present study indicate that the Chinese medicine, as an adjuvant to conventional treatment, appeared to be efficacious in enhancing cognitive function, reducing Chinese medicine syndrome score, improving blood biochemical markers, and improving cerebral blood flow perfusion in patients with CSVD, without any notable adverse reactions. However, it is imperative to validate these conclusions in future high-quality investigations.
