To investigate the effect of electroacupuncture (EA) at Neiguan (PC 6) on myocardial fibrosis in spontaneously hypertensive rats (SHRs), and to explore the contribution of interleukin-1 β (IL-1 β), insulin-like growth factor 1 (IGF-1), and transforming growth factor β 1 (TGF- β 1) to the effects.

Nine 12-weeks-old Wistar Kyoto (WKY) male rats were employed as the normal group. Twenty-seven SHRs were equally randomized into SHR, SHR+EA, and SHR + sham groups. EA was applied at bilateral PC 6 once a day 30 min per day in 8 consecutive weeks. After 8-weeks EA treatment at PC 6, histopathologic changes of collagen type I (Col I), collagen type 1 (Col 1) and the levels of IGF-1, 1L-1 β, TGF- β 1, matrix metalloproteinase (MMP)-2 and MMP-9 were examined in myocardial tissure respectively.

After 8-weeks EA treatment at PC 6, the enhanced myocardial fibrosis in SHRs were characterized by the increased mean fluorescence intensity of Col I and Col 1 in myocardium tissue (P<0.01). All these abnormal alterations above in SHR + EA group was significantly lower compared with the SHR group (P<0.01). Meanwhile, the increased levels of IL-1 β, IGF-1, TGF-β 1 in serum or myocardial tissue of SHRs, diminished MMP 9 mRNA expression in SHRs were also markedly inhibited after 8 weeks of EA treatment (P<0.05 or P<0.01). Furthermore, the contents of IL-1 β, IGF-1, TGF-β 1 in myocardial tissue were positively correlated with the systolic blood pressure and hydroxyproline respectively (P<0.01).

EA at bilateral PC 6 could ameliorate cardiac fibrosis in SHRs, which might be mediated by regulation of 1L-1 β/IGF-1-TGF- β 1-MMP9 pathway.

To study effects of Shenmai Injection on hypertensive heart failure and its mechanism for inhibiting myocardial fibrosis.

Salt-sensitive (Dahl/SS) rats were fed with normal diet (0.3% NaCl) and the high-salt diet (8% NaCl) to observe the changes in blood pressure and heart function, as the control group and the model group. Salt-insensitive rats (SS-13BN) were fed with the high-salt diet (8% NaCl) as the negative control group. After modeling, the model rats were randomly divided into heart failure (HF) group, Shenmai Injection (SMI) group and pirfenidone (PFD) group by a random number table, with 6 rats in each group. They were given sterilized water, SMI and pirfenidone, respectively. Blood pressure, cardiac function, fibrosis and related molecular expression were detected by sphygmomanometer, echocardiogram, enzyme linked immunosorbent assay (ELISA), hematoxylin-eosin staining, Masson staining, immunofluorescence and qPCR analysis.

After high-salt feeding, compared with the control and negative contribrosis is the main pathological manifestation of hypertensive heart failure, and Shenmai Injection could inhibit myocardial fibrosis and effectively improve heart failure by regulating TGF-β 1/Smad signaling pathway.

Interest has grown regarding the impact of social media platforms on mental health including body image and internalized weight bias (IWB) in those who have struggled with weight issues. However, few studies have addressed social media usage in bariatric patient samples. The objective of this study was to understand how the amount of time spent on social media could serve as a predictor for IWB in both pre- and post-operative bariatric patients.

Pre- and post-operative patients at one academic medical center completed self-report measures assessing patients’ IWB, depression, anxiety, body dissatisfaction, sociodemographic variables, and social media usage. Data were collected from March 2019 to April 2020. Statistical methods that included correlations, logistical regression models, and ANOVA analysis were used to determine the relationship between time spent on social media and other covariates.

A total of 148 responses were collected from the pre-surgical population, with 81 responses from the post-surgical sample. At baseline, the majority of respondents used social media for approximately 1h per day (n = 37; 27.82%). Time spent on social media was negatively associated with age (r =  - 0.24 [- 0.40, - 0.08]), and positively associated with IWB (r = 0.20 [0.02, 0.36]) and anxiety (r = 0.21 [0.01, 0.39]). In the post-operative group, only the 6-month BMI (r = 0.29 [0.05, 0.49]) was positively associated with time spent on social media.

Given this study’s findings, providers are encouraged to become aware of patients’ use of social media, and to understand the impact social media usage can have on the mental well-being of patients.

Conventional earlier embryo sex identification methods require professional technicians and sophisticated laboratory instruments. Rapid on-site gender identification of porcine embryos and pork products remains challenging. In this study, we developed a CRISPR/Cas12a-based fluorescence visualization point-of-care sex determination test that is rapid, accurate and easy to implement on-site. The CRISPR/Cas12a assay coupled with either the polymerase chain reaction (PCR) or loop-mediated isothermal amplification (LAMP) employs precisely designed primers and single-guide RNAs targeting the sex-determining region Y (SRY) and the zinc finger protein X-linked (ZFX) genes. PCR and LAMP amplicons were cleaved with the subsequent generation of fluorescing products detectable with portable blue and ultraviolet light transilluminators. Approximately two copies per microliter of the ZFX and SRY genes were detected using the RApid VIsual CRISPR (RAVI-CRISPR) assay. This method is a sensitive, inexpensive, versatile, and point-of-care test. The technology has other potential applications like determining the sex of diverse livestock species, detecting livestock disease-causing pathogens and evaluating the quality of meat products.Inflammatory breast cancer (IBC) is a rare and aggressive presentation of breast cancer, characterized by higher propensity for locoregional recurrence and distant metastasis compared with non-IBC. Because of extensive parenchymal and overlying dermal lymphatic involvement by carcinoma, IBC is unresectable at diagnosis. Trimodality therapy (neoadjuvant chemotherapy followed by modified radical mastectomy and adjuvant comprehensive chest wall and regional nodal radiotherapy) has been a well-accepted treatment algorithm for IBC. Over the last few decades, several innovations in systemic therapy have resulted in rising rates of pathologic complete response (pCR) in both the affected breast and the axilla. The latter may present an opportunity for deescalation of lymph node surgery in patients with IBC, as those with an axillary pCR may be able to avoid an axillary dissection. To this end, feasibility data are necessary to address this question. There are very limited data on the safety of breast conservation of IBC; therefore, mastectomy remains the standard of care for this disease. There are also no data addressing the safety of immediate reconstruction in patients with IBC. Considering that some degree of deliberate skin-sparing to facilitate immediate breast reconstruction would be expected, given the extensive skin involvement by disease at diagnosis, the safest oncologic strategy to breast reconstruction in IBC would be the delayed approach.

Treatment persistence was higher among the patients who initially received an anti-osteoporosis medication (AOM) with a long-dose-interval.

With long-dose-interval anti-osteoporosis medications (AOMs) available for osteoporosis management, it is important to evaluate persistence of any AOM as long as it is continuously used. The purpose of this study was to investigate the treatment pattern and persistence of AOMs, allowing for medication switch.

This study was an observational retrospective cohort study using Taiwan’s National Health Insurance claims data. We selected patients who first initiated an AOM between January 1, 2013, and June 30, 2016. AOM therapy included alendronate, raloxifene, teriparatide, denosumab, zoledronate, and ibandronate; the latter three were categorized as long-dose-interval medications. Persistence was defined as continual prescription of any AOM at a given time point with a grace period of 45days within which to obtain prescription refill. The competing risk model was used to examine the factors affecting patients switching their initial AOM.
