"Five-Step" Vaporization of the Prostate Using 180-W XPS Greenlight Laser in Patients with Benign Prostatic Hyperplasia of Large Volume: Improved Efficacy and Safety.

Objective: To evaluate the safety and efficacy of 180-W XPS Greenlight laser "Five-step" photoselective vaporization of the prostate (PVP) in patients with benign prostatic hyperplasia (BPH) with prostate volume (PV) > 80 mL. Background: In patients with BPH with large PV, PVP often results in bleeding, unclear visual field, additional damage, and insufficient tissue vaporization. Methods: This single-center, retrospective study enrolled patients with BPH with PV > 80 mL treated with the Five-step PVP or the Conventional PVP from January 2018 to June 2021. Comorbidities, high-risk habits, and operative parameters were analyzed and compared. The short-term functional outcomes and postoperative complications were recorded over the 24-month follow-up. Results: Two hundred eligible patients were divided into the Five-step PVP and Conventional PVP groups (n = 100 each). These groups showed no differences in comorbidities, living habits, baseline perioperative parameters, operative time, lasing time, or energy use. However, a higher energy density (3.95 [interquartile range (IQR) 3.37, 4.52] vs 3.68 [IQR 3.17, 4.20] kJ/mL) and energy-time ratio (7.23 [IQR 6.12, 8.52] vs 6.72 [IQR 5.51, 7.87] kj/min p = 0.034) were obtained in the Five-step PVP group. Subgroup analysis of patients with PV ≥120 mL showed similar results. The short-term functional outcomes were similar between the two study groups with significant improvement from baseline, but the total prostate-specific antigen levels at 1 and 6 months were lower in the Five-step PVP group. Further, incidences of intraoperative bleeding, bladder mucosa injury, postoperative hematuria, and urinary tract infection were lower in the Five-step PVP group. In the Conventional PVP group, four patients required conversion to transurethral resection of the prostate in surgery and two patients required retreatment during the 24-month follow-up. Conclusions: The 180-W XPS Greenlight laser Five-step PVP has advantages of less bleeding, high vaporization efficiency, and low rates of perioperative complications, and, therefore, it is a promising treatment to improve short-term functional outcomes for patients with BPH with large PV.

STS â ¡A inhibited angiogenesis of lung adenocarcinoma by activating FOXO3 to inhibit CXCL1/STAT3/VEGF pathway.

BACKGROUND: Lung adenocarcinoma (LUAD) is the most popular type of lung cancer. Sulfotanshinone IIA sodium (STS IIA) has been proven to have an anticancer effect. However, its role in LUAD and its underlying mechanism remain unclear. OBJECTIVE: To investigate the role and mechanism of STS IIA in LUAD angiogenesis. METHODS: The mRNA levels of genes, including forkhead box O3 (FOXO3) and chemokine C-X-C motif ligand 1 (CXCL1), were detected by qRT-PCR. The levels of proteins, including FOXO3, CXCL1, and vascular endothelial growth factor (VEGF), were measured by Western blot. The proliferation and angiogenesis of human umbilical vein endothelial cells (HUVECs) were detected by the EdU assay and the tubule formation assay, respectively. The binding relationship between FOXO3 and CXCL1 was detected by dual-luciferase reporter assay. RESULTS: Our results illustrated that different concentrations of STS IIA inhibited the proliferation and angiogenesis of HUVECs. FOXO3 regulated the proliferation and angiogenesis of HUVECs inhibited by STS ⅡA via targeting CXCL1. Subsequently, we proved that exogenous CXCL1 alleviated the inhibition of proliferation and angiogenesis of HUVECs regulated by STS IIA via activating the STAT3/VEGF pathway. Finally, we found that STS IIA inhibited the angiogenesis of lung adenocarcinoma though FOXO3 to inhibit the CXCL1/STAT3/VEGF pathway. CONCLUSION: Our study finally elucidated the underlying molecular mechanism by which STS ⅡA inhibits LUAD angiogenesis.

Gut microbiota, circulating cytokines and dementia: a Mendelian randomization study.

BACKGROUND: Some studies have shown that gut microbiota may be associated with dementia. However, the causal effects between gut microbiota and different types of dementia and whether cytokines act as a mediator remain unclear. METHODS: Gut microbiota, cytokines, and five dementia types, including Alzheimer's disease (AD), frontotemporal dementia (FTD), dementia with Lewy body (DLB), vascular dementia (VD), and Parkinson's disease dementia (PDD) were identified from large-scale genome-wide association studies (GWAS) summary data. We used Mendelian randomization (MR) to investigate the causal relationships between gut microbiota, cytokines, and five types of dementia. Inverse variance weighting (IVW) was used as the main statistical method. In addition, we explored whether cytokines act as a mediating factor in the pathway from gut microbiota to dementia. RESULTS: There were 20 positive and 16 negative causal effects between genetic liability in the gut microbiota and dementia. Also, there were five positive and four negative causal effects between cytokines and dementias. Cytokines did not act as mediating factors. CONCLUSIONS: Gut microbiota and cytokines were causally associated with five types of dementia, and cytokines seemed not to be the mediating factors in the pathway from gut microbiota to dementia.

Short-term curative effect of electroacupuncture as an adjunctive treatment on schizophrenia / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To compare the short-term curative effect of clozapine (CZ) and its combination with electroacupuncture (EA) in treating schizophrenia.</p><p><b>METHODS</b>Ninety schizophrenia patients were randomly divided into two groups equally: the EA group treated with combination of CZ (200 - 300 mg/d in mean) and EA, and the CZ group treated with CZ alone. The effects of treatment were evaluated with PANSS, CGI and TESS before and at the 2th, 4th, 6th and 8th weekend of the treatment.</p><p><b>RESULTS</b>The initiation of effect in the two groups was the same, the total effective rate was 75% in the EA group and 73% in the CZ group. However, somatic complaint was lower and compliance was higher in the EA group than that in the CZ group respectively.</p><p><b>CONCLUSION</b>With the effect equal to CZ, combination of CZ and EA shows higher compliance in treating schizophrenia, which would be beneficial in the later stage treatment for consolidation.</p>
