The therapeutic efficacy of guided therapy for PCI after acute myocardial infarction: A meta-analysis.

OBJECTIVE: To systematically evaluate the effects of lead therapies on percutaneous coronary intervention (PCI) after acute myocardial infarction (AMI). METHODS: A randomized controlled trial (RCT) in the CNKI, Wanfang, VIP, ProQuest, PubMed, Cochrane Library, Scopus, and Web of Science databases was searched until January 2023. Two researchers strictly screened and checked the included literature, extracted relevant data, and used the Cochrane Manual to assess the risk quality of the literature. Using RevMan 5.3 software, Meta-analysis of 4 main outcome measures [cardiac function-related indicators, 6-minute walking distance (6 MWT), quality of life (SF-36), Seattle angina pectoris scale (SAQ)], and 3 secondary outcome measures [adverse event incidence, death incidence, and readmission rate]. RESULTS: 22 studies were finally included with 1754 subjects, but the overall quality of the included studies was not high. The results of the meta-analysis showed that, in the cardiac function-related indicators compared to controls, improved left ventricular ejection fraction (LVEF) index (MD = 1.42, 95%CI [-0.94, 3.79], P < .00001); however, compared with the Baduanjin group, Tai Chi ball + Baduanjin group and control group, there was no significant difference (P > .05); compared with the control group, the guidance therapy group improved the left ventricular end-diastolic volume (LVEDV) index (MD = -4.67, 95%CI [-6.8, -2.71], P < .00001). In comparison, the lead group improved the 6 MWT (MD = 69.44, 95%CI [30.12, 108.76], P < .00001); the SF-36 score (MD = 10.05, 95%CI [8.68, 11.42], P < .00001])and the SAQ score (MD = 6.2, 95%CI [3.97, 8.44], P < .00001). Among the secondary outcome measures, the incidence of adverse events was statistically significant (RR = 0.17, 95%CI [0.1, 0.32], P < .00001); statistically significant (RR = 0.29, 95%CI (0.1, 0.87), P < .00001); readmission (RR = 0.39, 95%CI [0.17, 0.87, 0.89], P < .00001). CONCLUSION: Based on the current study, combining conventional therapy/ exercise or using simple lead therapy after PCI can improve the treatment effect and improve the quality of life.

Effect of repetition of rTMS at different frequencies on the efficacy of swallowing disorders after stroke: A systematic review and meta-analysis.

BACKGROUND: To systematically evaluate the curative effect of repeated transcranial magnetic stimulation at different frequencies on swallowing disorders after stroke. METHODS: A search was conducted for randomized controlled trials of repeated transcranial magnetic stimulation for stroke patients in CNKI, Wanfang, VIP, ProQuest, PubMed, Cochrane Library, Scopus, and Web of Science databases until December 2022. The 2 researchers strictly screened and checked the included documents, extracted relevant data, assessed the risk quality of the literature using the Cochrane manual, and conducted a network meta-analysis of the data using State16.0. RESULTS: Eighteen studies included 680 participants. The results of the reticular meta-analysis showed that in the leakage-aspiration scale (PAS) indicators, 1 Hz, 3 Hz, 5 Hz, and 10 Hz were all better treatment effects compared with the control group, and there was a statistically significant difference (P < .05). In the standard swallowing function assessment (SSA) index, 3 Hz, 5 Hz, and 10 Hz compared with the control group were statistically significant (P < .05); there was no difference between 1 Hz and the control group (P > .05). The cumulative probability ranking results showed that the intervention effect of 3 Hz was the best in the PAS index, much greater than that of other frequencies, and the intervention effects of 10 Hz and 5 Hz were similar. For the SSA index, the intervention effect was optimal at 10 Hz, followed by 5 Hz. Note that the treatment effect of 1 Hz ranked last, even lower than that of the control group. The results of the 5 Hz treatment site grouping analysis showed that the affected side was > bilateral > healthy in PAS and > bilateral > healthy in SSA. CONCLUSION SUBSECTIONS: Based on the current study, the optimal frequency and site selection results of the 2 evaluation indicators are not uniform, but from the combination of the 2 evaluation indicators, the treatment effect of 10H is good, and the effect of bilateral stimulation for the selection of stimulation sites is good. The above conclusions need to be verified in high-quality studies.

Transcriptome sequencing revealed molecular mechanisms underlying tolerance of Suaeda salsa to saline stress.

The halophyte Suaeda salsa displayed strong resistance to salinity. Up to date, molecular mechanisms underlying tolerance of S. salsa to salinity have not been well understood. In the present study, S. salsa seedlings were treated with 30‰ salinity and then leaves and roots were subjected to Illumina sequencing. Compared with the control, 68,599 and 77,250 unigenes were significantly differentially expressed in leaves and roots in saline treatment, respectively. KEGG enrichment analyses indicated that photosynthesis process, carbohydrate, lipid and amino acid metabolisms were all downregulated in saline treatment, which should inhibit growth of S. salsa. Expression levels of Na+/H+ exchanger, V-H+ ATPase, choline monooxygenase, potassium and chloride channels were upregulated in saline treatment, which could relieve reduce over-accumulation of Na+ and Cl-. Fe-SOD, glutathione, L-ascorbate and flavonoids function as antioxidants in plants. Genes in relation to them were all upregulated, suggesting that S. salsa initiated various antioxidant mechanisms to tolerate high salinity. Besides, plant hormones, especially auxin, ethylene and jasmonic acid signaling transduction pathways were all upregulated in response to saline treatment, which were important to gene regulations of ion transportation and antioxidation. These changes might comprehensively contribute to tolerance of S. salsa to salinity. Overall, the present study provided new insights to understand the mechanisms underlying tolerance to salinity in halophytes.

[Effects of packaging on the stability of vitamin E in peach kernels stored at high temperature].

Peach kernels with three different kinds of packaging, including routine, vacuum and edible film, were put into an accelerated test in order to study the effects of packaging on the stability of vitamin E, gamma-, alpha-, and delta-tocopherol. The result indicated that among the three kinds of packaging, the stability of vitamin E in the samples with vacuum packaging was the best, and with routine packaging was the worst. And for the samples with the same kind of packaging, the stabilities of gamma-, alpha- and delta-tocophero decreased one by one.
