Cryptotanshinone (CT), a lipophilic compound extracted from roots of
Bunge (Lamiaceae) (Danshen), has multiple properties in diseases, such as pulmonary fibrosis, lung cancer, and osteoarthritis. Our previous findings suggest that CT plays a protective role in cerebral stroke. However, the molecular mechanisms underlying CT protection in ischaemic stroke remain unclear.

This study examines the effect of CT on ischaemic stroke.

We used the middle cerebral artery occlusion (MCAO) rat (Sprague-Dawley rats, 200 ± 20 g,
 = 5) model with a sham operation group was treated as negative control. MCAO rats were treated with 15 mg/kg CT using intragastric administration. Moreover, TGF-β (5 ng/mL) was used to treat MCAO rats as a positive control group.

The 50% inhibitory concentration (IC
) of CT on CD4
cell damage was 485.1 μg/mL, and median effective concentration (EC
) was 485.1 μg/mL. CT attenuates the infarct region in the MCAO model. The percentage of CD4
CD25
FOXP3
Treg cells in the peripheral blood of the MCAO group was increased with CT treatment. The protein level of FOXP3 and the phosphorylation of STAT5 were recovered in the CD4
CD25
Treg cells of model group after treated with CT. Importantly, the effects of CT treatment were blocked by treatment with the inhibitor STAT5-IN-1 in CD4
T cells of the MCAO model.

Our findings not only enhance the understanding of the mechanisms underlying CT treatment, but also indicate its potential value as a promising agent in the treatment of ischaemic stroke. Further study will be valuable to examine the effects of CT on patients with ischaemic stroke.

However, research on older cannabis users, especially medical cannabis users, is scant.Objectives We examined medical and nonmedical cannabis users aged 50+ on health-related characteristics, cannabis use patterns, and cannabis sources. Hypotheses were that compared to nonmedical users, medical users are more likely to have physical and mental health problems, use healthcare services, discuss their drug use with a healthcare professional, use cannabis more frequently, and purchase cannabis from a medical dispensary and other sources rather than obtain it as a gift, share someone else's, or use other means.Methods We used 2018 and 2019 National Survey on Drug Use and Health data (N = 17,685 aged 50+; male = 8,030; female = 9,655). Hypotheses were tested using logistic regression analysis.Results The past-year cannabis use rate was 8.9%. Of past-year users, 18.5% reported medical use. Compared to nonmedical use, medical use was associated with lower odds of alcohol use disorder but higher odds of discussing drug use with a healthcare professional (AOR = 4.18, 95% CI = 2.53-6.89), high-frequency use (e.g., AOR = 2.56, 95% CI = 1.35-4.86 for 200-365 days), and purchase at a medical cannabis dispensary (AOR = 4.38, 95% CI = 2.47-7.76).Conclusion Medical and nonmedical users did not differ on physical and most behavioral health indicators. Most obtained cannabis from private/informal sources. Some medical users are likely to self-treat without healthcare professional consultation. Healthcare professionals should engage older adults in discussions of cannabis use and behavioral health needs.
Given barriers of patient-centred care (PCC) among physicians and trainees, this study assessed how medical schools addressed PCC in curriculum.

The authors used content analysis to describe PCC in publicly-available curriculum documents of Canadian medical schools guided by McCormack's PCC Framework, and reported results using summary statistics and text examples.

The authors retrieved 1459 documents from 16 medical schools (median 49.5, range 16-301). Few mentioned PCC (301, 21.2%), and even fewer thoroughly or accurately described PCC. Significantly more clerkship versus pre-clerkship (24.0% vs 12.6%,
 < 0.00001), and elective compared with core course descriptions (24.7% vs 14.9%,
 < 0.00001) mentioned PCC. The domain of foster a healing relationship was common (79.0%) compared with other domains address concerns (16.5%), exchange information (14.9%), enable self-care (10.4%), share decisions (4.5%), and manage uncertainty (1.3%).

Overall, few documents mentioned or described PCC or related concepts. This varied by school, and was more frequent in clerkship and elective courses, suggesting that student exposure may be brief and variable. Thus, it remains unclear if medical students are fully exposed to what PCC means and how to implement it. Future research is needed to confirm if PCC content in medical curriculum is lacking.

Thonningianin A is an ellagitannin substance and displays multiple pharmacological activities.

This study investigated the pharmacokinetic characteristics of thonningianin A after oral administration in rats using a fully validated liquid chromatography tandem mass spectrometry (LC-MS/MS) method.

A sensitive and selective LC-MS/MS assay was developed for quantifying thonningianin A. Eighteen Wistar rats were randomly divided into three groups (
 = 6), which were given at a single dose of 10, 20, or 40 mg/kg thonningianin A by gavage. Blood samples (200 µL) were collected from the orbit vein at designated time points and analyzed using the LC-MS/MS method to measure the levels of thonningianin A.

Thonningianin A and internal standard (IS) were eluted at 1.5 and ∼3.0 min, respectively. The selected reaction mode transitions monitored were
873.2 > 300.3 and 819.3 > 610.6 for thonningianin A and the IS, respectively. The calibration range was 10-1200 ng/mL. The intra- and the inter-day accuracy s study should be helpful for providing references for understanding the action mechanism and further application of Penthorum chinense.
Ear reconstruction is a challenging surgery for the complicated conditions in patients with microtia. The tissue expansion techniques were necessary and relatively safe for patients with insufficient soft tissue. However, complications such as necrosis of expanded flap and exposure of tissue expander limited the popularization of this method. This study described the use of modified Brent method to handle the exposure of the postauricular tissue expander.

From January 2013 to December 2019, 27 ear reconstruction patients with trauma or necrosis on an expanded skin flap and subsequent exposure of tissue expander were treated with modified Brent method, which consisted of 3 stages removal of the expander, tension-free closure of wound, and framework fabrication; elevation of reconstructed ear; lobule rotation; and minor modification.

Fifty-six percent of exposures occurred in the lower pole of the tissue expander. Exposure usually occurred 54.5 days after implantation. The majority of reconstructed ears had a satisfactory appearance and showed relatively stable outcomes. Only one case of cartilage exposure required revision surgery and was repaired by the temporoparietal fascia.

With reasonable distribution of expanded flap, prolonged interval, and sutures under tension-free conditions, complications like the occurrence of trauma or necrosis-induced exposure of tissue expander can be repaired efficiently by a staging modified Brent method.

The presence of clinically detectable papillary thyroid carcinoma (PTC) metastases in the lateral neck is an indication for neck dissection (ND) and thyroidectomy. Although there is a consensus regarding the importance of therapeutic selective ND of involved levels II to IV in patients with clinically evident locoregional metastatic disease, the prognostic benefit of level V prophylactic ND remains debatable.

All patients who underwent thyroidectomy with ND for metastatic PTC between 2006 and 2019 were included in a single-institution retrospective study. Preoperative characteristics at initial presentation, imaging workup, intraoperative findings, and the final histopathological reports were retrieved from the institutional database.

A total of 189 patients with locally advanced PTC were identified, of whom 22 (11.6%) patients underwent therapeutic selective ND at levels II to IV together with level V dissection due to clinical involvement. Comparison of the patients who were operated on level V to thoV dissection and risk for recurrence. Recurrence at level V was rare (4/189 patients, 2.1%). ML348 purchase Our study's findings suggest a low prophylactic benefit of an elective level V ND. Elective level V ND should not be done routinely when lateral ND is indicated but should rather be considered after careful evaluation in high-risk patients.A dehiscent high jugular bulb would be a pitfall in middle ear surgery especially for cholesteatoma. We report a case of cholesteatoma attached to a dehiscent high jugular bulb successfully treated with surgery assisted with underwater endoscopy. To the best of our knowledge, no previous study has reported a case of cholesteatoma with dehiscent high jugular bulb treated with surgery assisted with underwater endoscopy. Owing to the risk of jugular bulb injury, underwater endoscopy is a good indication for middle ear cases with a dehiscent high jugular bulb to obtain a clear operative field and avoid an unexpected air embolism.
To analyze the role of factors that influence adenoid-related symptoms, and the influence of 3 months of isolation in preschool children who were qualified for adenoidectomy.

This was a cohort study of the impact of 3 months of isolation on children aged 3 to 6 years with adenoid-related symptoms and endoscopically confirmed grade II and III adenoid hypertrophy. The children had previously qualified for adenoidectomy. After 3 months, 141 children were asked about their symptoms, 71 of whom were randomly chosen for medical examination, including endoscopic adenoid examination. Additionally, pre- and post-isolation tympanometry results were analyzed.

In our study, significant or mild improvements in health were observed in approximately 73% of the children; 92% of the surveyed parents reported that their children exhibited improved nasal patency, 63% of children discontinued snoring, and 30% of children showed a decrease in snoring. Data collected through surveys correlated with endoscopic findings wherein the size of the adenoid decreased by an average of 5.
