Building and Realizing the Obstetrics and Gynecology Nursing Management Platform by Computer Information Technology under the Concept of Mindfulness Intervention.

Nursing management of the gynecology department is one of the challenging issues and needed to be resolved through effective utilization of the available technology. In this paper, we are going to address this issue and try to establish an obstetrics and gynecology nursing management platform used to monitor and evaluate the mental health of pregnant women. Firstly, computer information technology is adopted, and the obstetrics and gynecology nursing management system is established. Secondly, after adopting the system to intervene in the mental state of patients with mindfulness, the system timely monitors the pregnant women's physical health indicators and mental health level data. With the help of the computer data analysis system, the obstetrics and gynecology management platform is built to carry out timely mindfulness interventions for pregnant women. The established system can reach high accuracy in identifying negative emotions of pregnant women, and the accuracy can reach 89.7%. It shows that the established system can timely and accurately intervene and regulate the pregnant woman's bad psychological state, effectively improve the pregnant woman's sleep quality during pregnancy, and enhance the pregnant woman's sleep effect. The effectiveness and feasibility of Internet mindfulness interventions for improving sleep quality during pregnancy has been confirmed. This has important practical significance for the digital and intelligent development of the medical care management platform.

Prevalence and risk factors for incidental prostate cancer in patients after transurethral resection of the prostate with negative results on prostate biopsy: A retrospective study.

PURPOSE: This study aimed to explore the prevalence and predictors of incidental prostate cancer (IPC) after transurethral resection of the prostate (TURP) with negative results on transperineal magnetic resonance imaging (MRI)/transrectal ultrasonography (TRUS) fusion prostate biopsy or TRUS-guided prostate biopsy. MATERIALS AND METHODS: Data of 253 patients who underwent TURP with a preliminary diagnosis of benign prostatic hyperplasia (BPH) were evaluated. The prevalence of IPC was calculated. Univariate and multivariate logistic regression analyses were conducted to explore independent predictive factors of IPC. RESULTS: A total of 253 patients were included. IPC was diagnosed in 12 patients (4.7%). The mean age of the patients and the mean prostate volume were 69.8±7.07 years and 89.3±49.29 mL, respectively. The prevalence of IPC was higher in the TRUS guided prostate biopsy group than in the transperineal MRI/TRUS fusion prostate biopsy group (11 of 203 [5.4%] vs. 1 of 50 [2.0%], p=0.47), but the difference was not statistically significant. Our results indicated that older age (≥70 y) (odds ratio [OR], 1.14; 95% confidence interval [CI], 1.02-1.27; p=0.025) and smaller prostate volume (OR, 0.97; 95% CI, 0.938-0.998; p=0.039) were associated with an increased incidence of IPC after TURP. CONCLUSIONS: Our findings indicate that the prevalence of IPC may be higher among patients who undergo transrectal prostate biopsy before TURP than among those who undergo transperineal MRI/TRUS fusion prostate biopsy. Older age and smaller prostate volume were independent predictors of increasing the risk for IPC after TURP.

Prevalence and risk factors of incidental prostate cancer in certain surgeries for benign prostatic hyperplasia: A systematic review and meta-analysis.

BACKGROUND: This study aimed to explore the prevalence and clinical risk factors in patients diagnosed with incidental prostate cancer (IPC) during certain surgeries (transurethral resection of the prostate [TURP], open prostatectomy [OP], and holmium laser enucleation of the prostate [HoLEP]) after clinically suspected benign prostatic hyperplasia (BPH). MATERIALS AND METHODS: Literature search of the MEDILINE, Web of Science, Embase, and Cochrane Library databases was performed to identify eligible studies published before June 2021. Multivariate adjusted odds ratios (ORs) and associated 95% confidence intervals (CIs) of the prevalence and clinical risk factors of IPC were calculated using random or fixed-effect models. RESULTS: Twenty-three studies were included in the meta-analysis. Amongst the 94.783 patients, IPC was detected in 24.715 (26.1%). Results showed that the chance of IPC detection (10%, 95% CI: 0.07-4.00; P<0.001; I2=97%) in patients treated with TURP is similar to that of patients treated with HoLEP (9%, 95% CI: 0.07-0.11; P<0.001; I2=81.4%). However, the pooled prevalence estimate of patients treated with OP was 11% (95% CI: -0.03-0.25; P=0.113; I2=99.1%) with no statistical significance. We observed increased incidence of IPC diagnosis after BPH surgery amongst patients with higher prostate-specific antigen (PSA) level (OR: 1.13, 95% CI: 1.04-1.23; P=0.004; I2=89%), whereas no effect of age (OR: 1.02, 95% CI: 0.97-1.06; P=0.48; I2=78.8%) and prostate volume (OR: 0.99, 95% CI: 0.96-1.03; P=0.686; I2=80.5%) were observed. CONCLUSIONS: The prevalence of IPC was similar amongst patients undergoing TURP, HoLEP, and OP for presumed BPH. Interestingly, increased PSA level was the only independent predictor of increasing risk of IPC after BPH surgery rather than age and prostate volume. Hence, future research should focus on predictors which accurately foretell the progression of prostate cancer to determine the optimal treatment for managing patients with IPC after BPH surgery.

Ginkgolide B Alleviates Learning and Memory Impairment in Rats With Vascular Dementia by Reducing Neuroinflammation via Regulating NF-κB Pathway.

Ginkgobalide B (GB) as the main active ingredient of traditional Chinese medicine Ginkgo biloba extract is reported to reduce neuroinflammation, protect neurons and promote cognitive learning ability. To explore that GB can reduce neuroinflammation through regulating nuclear factor-kappaB (NF-κB) signaling pathway and overcome cognitive dysfunction in rats with vascular dementia (VD), we aim at investigating the potential effect of GB on enhancing cognitive function in rats with VD. It was found that GB improved survival of oxygen-glucose deprivation (OGD) treated SH-SY5Y cells by attenuating inflammatory response via Toll-like Receptor 4 (TLR4)/NF-κB pathway. When rats were treated with bilateral common carotid artery occlusion (BCCAO) for 24 h, saline and GB were administered in Sprague-Dawley (SD) rats via a single intraperitoneal injection for consecutive 14 days. The behavioral changes of VD like rats treated with GB were observed through open field test, Morris water maze (MWM) and Y-maze electric maze. Nissl staining and immunofluorescence were used to observe changes of neurons in the hippocampus of rats. Western blot analysis was performed by detecting NF-κB pathway related inflammatory factors. The results found that GB can significantly improve the learning and memory ability of VD rats by reducing TLR4/NF-κB mediated neuroinflammation. In conclusion, GB seemed to be a potential drug for amelioration of learning and memory impairment in rats with VD.

Identification of a novel tumor angiogenesis inhibitor targeting Shh/Gli1 signaling pathway in Non-small cell lung cancer.

Although angiogenesis inhibitors targeting VEGF/VEGFR2 have been applied for tumor therapy, the outcomes are still unsatisfactory. Thus, it is urgent to develop novel angiogenesis inhibitor for cancer therapy from new perspectives. Identification of novel angiogenesis inhibitor from natural products is believed to be one of most promising strategy. In this study, we showed that pristimerin, an active agent isolated from traditional Chinese herbal medicine Celastrus aculeatus Merr, was a novel tumor angiogenesis inhibitor that targeting sonic hedgehog (Shh)/glioma associated oncogene 1 (Gli1) signaling pathway in non-small cell lung cancer (NSCLC). We showed that pristimerin affected both the early- and late-stage of angiogenesis, suggesting by that pristimerin inhibited Shh-induced endothelial cells proliferation, migration, invasion as well as pericytes recruitment to the endothelial tubes, which is critical for the new blood vessel maturation. It also suppressed tube formation, vessel sprouts formation and neovascularization in chicken embryo chorioallantoic membrane (CAM). Moreover, it significantly decreased microvessel density (MVD) and pericyte coverage in NCI-H1299 xenografts, resulting in tumor growth inhibition. Further research revealed that pristimerin suppressed tumor angiogenesis by inhibiting the nucleus distribution of Gli1, leading to inactivation of Shh/Gli1 and its downstream signaling pathway. Taken together, our study showed that pristimerin was a promising novel anti-angiogenic agent for the NSCLC therapy and targeting Shh/Gli1 signaling pathway was an effective approach to suppress tumor angiogenesis.

Phosphorus Leaching from Soil Profiles in Agricultural and Forest Lands Measured by a Cascade Extraction Method.

The risk of P leaching from topsoil based on the change-point estimated via a split-line model between Olsen P and leachable P extracted by 0.01 M CaCl has been reported. However, little information is available for the assessment of P leaching from soil profiles. In this study, samples were collected at three depth profiles (0-20 cm, topsoil; 20-40 cm, subsoil; 40-60 cm, third-layer soil) at each of 74 sites under agriculture and forest in an agroforestry area. A cascade extraction method was proposed to determine the leachable P in the subsoil, extracted by the topsoil extraction solution; a similar extracted process was followed in the third-layer soil, and in the topsoil, it was still extracted by 0.01 M CaCl. A positive linear correlation was found between the subsoil leachable P extracted by the topsoil extraction solution and the accumulated P obtained from the subsoil leached by topsoil leachates, and so on. Therefore, the cascade extraction method for determining leachable P from topsoils and underlying soils could be valuable for predicting the potential of P leaching from soil profiles. Approximately 81, 73, and 73% of the agricultural sampling sites were at or above the change-points for the soil depths of 0 to 20, 20 to 40, and 40 to 60 cm (30.4, 32.9, and 18.2 mg kg respectively); these values were higher than those for the forest site, implying a high risk of P leaching from agricultural soil profiles in the study area.

Fuxin decoction attenuates doxorubicin-induced heart failure in rats via oxidizing suppression and regulating immune responses.

OBJECTIVE: To observe the effects of Fuxin decoction in rats with heart failure induced by doxorubicin injections. METHODS: We employed a doxorubicin-induced heart failure model to investigate the effect of Fuxin decoction. Rats were orally administered with Fuxin decoction from 10 to 40 mg/kg. Organization structure changes were assessed by histology, circulating levels of oxidative stress-related biomarkers and inflammatory cytokines were detected via enzyme-linked immunosorbent assay. RESULTS: Administration of Fuxin decoction improved the growth retardation in doxorubicin hydrochloride injection rats. Cardiac involvement was alleviated by Fuxin decoction, as well as changes of congestion systemic circulation in this rat models. Furthermore, Fuxin decoction regulates immune responses and suppresses oxidation reaction in doxorubicin hydrochloride-induced rats. CONCLUSION: Fuxin decoction might be an interesting candidate for congestive heart failure.

Dimethyl Labeling Coupled with Mass Spectrometry for Topographical Characterization of Primary Amines on Monoclonal Antibodies.

Site-specific solvent accessibility of the primary amines (mainly lysine or the N-termini) on proteins is of great interest in many research areas because amines are an important functional group for protein conjugation. In this study, we coupled dimethyl labeling via reductive amination with liquid chromatography-mass spectrometry (LC-MS) to fully characterize the solvent accessibility of lysine residues and the N-termini on human immunoglobulin G (IgG). Circular dichroism (CD) and fluorescence spectroscopy revealed that dimethyl labeling did not alter the conformation of the native IgG molecule. Based on intact protein measurements, up to 28 (light chain) and 66 (heavy chain) dimethyl tags, covering all lysine residues and the N-termini, were sequentially incorporated into IgG molecules in 1000 s. All labeled sites were identified and quantified by a bottom-up proteomics approach. Some highly exposed hot-spots (for example, the N-termini of both the heavy and the light chains) and some buried sites (for example, K415 in the heavy chain and K39 in the light chain) were unambiguously revealed. This method was also used to characterize aggregation-induced structural changes in IgGs by increasing the temperature. Substantial changes in the labeling percentage of many lysine sites were observed, indicating a non-native aggregation triggered by thermal stress. Due to high labeling yields and the van der Waals surface of the labeling reagents being comparable to that of water, dimethyl labeling is a highly promising technique for probing the amine's surface topography of proteins. It can also be used as a complementary approach to other methods for resolving the higher-order structure of proteins by LC-MS.

Astaxanthin ameliorates cartilage damage in experimental osteoarthritis.

PURPOSE: Astaxanthin is a red-pigment carotenoid found in certain marine animals and plants. Astaxanthin has been shown to inhibit matrix metalloproteinases (MMPs) expression in vitro. However, the effect of astaxanthin on cartilage is still unclear. The aim of this study was to investigate the effects of astaxanthin on cartilage in experimental osteoarthritis (OA). METHODS: New Zealand rabbits underwent anterior cruciate ligament transection to induce OA in right knee. Rabbits received intra-articular injection containing 0.3 ml of vehicle (dimethyl sulfoxide) or astaxanthin (50 µM). Injection was started on the day of operation, and the injection were performed once weekly for six consecutive weeks. Then, rabbits were sacrificed and the right knees were harvested for study. RESULTS: Cartilage degradation was reduced by astaxanthin, as assessed by morphological and histological examination. Astaxanthin inhibited the gene expression of MMP-1, MMP-3, and MMP-13 in cartilage as compared with the vehicle group. CONCLUSIONS: The results suggest that astaxanthin may be considered as pharmaceutical agent in OA treatment.

Treatment of ocular itching associated with ocular demodicosis by 5% tea tree oil ointment.

PURPOSE: To determine whether ocular itching associated with ocular demodicosis can be treated by lid massage with 5% tea tree oil ointment (TTOO). METHODS: Twenty-four patients with ocular itching and ocular Demodex were treated with chlortetracycline hydrochloride eye ointment lid massage for 4 weeks and then treatment was switched to TTOO for another 4 weeks. They were examined every 2 weeks and their itching was graded as 0 (none), 1 (mild), 2 (moderate), or 3 (severe). Changes of itching scores and Demodex counts were compared. RESULTS: Before the treatment, all 24 patients reported itching graded as 1 (n = 3), 2 (n = 15), and 3 (n = 6) for a period of 2 weeks to 2 years despite previous topical antibiotics, antiinflammatory medications, or antiallergy medications. Demodex counts per 8 epilated lashes were 5.5 ± 1.6 for all patients but 4.6 ± 1.5, 4.8 ± 1.9, and 7.1 ± 2.1 for patients with grade 1, grade 2, and grade 3 itchiness, respectively (P < 0.05 between grade 2 and grade 3). After 4 weeks of chlortetracycline hydrochloride eye ointment treatment, little changes were observed regarding itching and Demodex counts in all patients (P > 0.05). In contrast, after 5% TTOO treatment, 16 patients were totally free of itching and the remaining 8 patients had different degrees of relief (P < 0.01). The Demodex count decreased to 0.7 ± 0.8 for total (P < 0.01). CONCLUSIONS: There is a strong correlation between ocular itching and Demodex infestation and between symptomatic resolution and reduction of Demodex counts by daily lid massage with 5% TTOO.

[Preliminary exploration on effect of yiqi wenyang huoxue lishui treatment on neuroendocrine system in patients with congestive heart failure].

OBJECTIVE: To study the effect of Yiqi Wenyang Huoxue Lishui principle (YWHL, a therapeutic principle with Chinese medicine for reinforcing Qi warming Yang, activating blood circulation and promoting urination) on some neuroendocrine factors in patients with congestive heart failure (CHF). METHODS: Forty-nine patients of CHF with heart function of grade III-IV were randomly divided into 2 groups. The 29 cases in the treated group were treated with YWHL and the 20 cases in the control group treated with captopril. Changes of angiotensin II (AT II), atrial natriuretic peptide (ANP), endothelin (ET), nitric oxide (NO) and alpha-granule membrance protein -140 (GMP-140) were observed. RESULTS: After treatment, plasma level of AT II, ANP, ET, and NO lowered in both groups with insignificant difference, but the GMP-140 reduced more significantly in the treated group (P < 0.05). CONCLUSION: YWHL showed a regulatory effect of neuroendicrine system partially similar to that of angiotensin-converting enzyme inhibitor, it possibly can improve the ventricular remodeling and would be beneficial to prevent the thrombus formation and improve heart failure by means of inhibiting platelet activity.
