ObjectiveTo decipher the mechanism by which Zuoguiwan (ZGW) treat hyperthyroidism in rats with kidney-Yin deficiency based on the dopamine receptor D4 (DRD4)/nicotinamide adenine dinucleotide phosphate (NADPH) oxidase 4 (NOX4) signaling pathway. MethodsThe rat model of kidney-Yin deficiency was induced by unilateral intramuscular injection of dexamethasone (0.35 mg·kg-1). After successful modeling, the rats were randomized into model, methimazole (positive control, 5 mg·kg-1), low-, medium-, and high-dose (1.85, 3.70, 7.40 g·kg-1, respectively) ZGW, and normal control groups. After 21 days of continuous gavage, the behavioral indexes and body weight changes of rats were evaluated. The pathological changes of the renal tissue were observed by hematoxylin-eosin staining. The serum levels of thyroid hormones [triiodothyronine (T3), thyroxine (T4), thyroid-stimulating hormone (TSH)], renal function indexes [serum creatine (Scr) and blood urea nitrogen (BUN)], energy metabolism markers [cyclic adenosine monophosphate (cAMP) and cyclic guanosine monophosphate (cGMP)], and oxidative stress-related factors [superoxide dismutase (SOD), malondialdehyde (MDA), and NADPH)] were measured by enzyme-linked immunosorbent assay (ELISA). Western blot was employed to analyze the expression of DRD4, NOX4, mitochondrial respiratory chain complex proteins [NADH:ubiquinone oxidoreductase subunit S4 (NDUFS4) and cytochrome C oxidase subunit 4 (COX4)], and inflammation-related protein [tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), p38 mitogen-activated protein kinase (MAPK)] pathway in the renal tissue. ResultsCompared with the normal group, the model group showed mental malaise, body weight decreases (P<0.01), inflammatory cell infiltration in the renal tissue, a few residual parotid glands in the thyroid, elevations in serum levels of T3, T4, Scr, BUN, cAMP, cAMP/cGMP, MDA, and NADPH (P<0.01), down-regulation in protein levels of TSH, SOD, and DRD4 (P<0.05, P<0.01), and up-regulation in expression of NOX4, p-p38 MAPK/p38 MAPK, and inflammatory factors (P<0.01). Compared with the model group, ZGW increased the body weight (P<0.05, P<0.01), reduced the infiltration of renal interstitial inflammatory cells, restored the thyroid structure and follicle size, lowered the serum levels of T3, T4, Scr, BUN, cAMP, cAMP/cGMP, MDA and NADPH (P<0.05, P<0.01), up-regulated the expression of TSH, SOD and DRD4 (P<0.05, P<0.01), and down-regulated the expression of NOX4, p-p38 MAPK/p38 MAPK, and inflammatory factors (P<0.05, P<0.01). Moreover, high-dose ZGW outperformed methimazole (P<0.05). ConclusionBy activating DRD4, ZGW can inhibit the expression of NOX4 mediated by the p38 MAPK pathway, reduce oxidative stress and inflammatory response, thereby ameliorating the pathological state of hyperthyroidism due to kidney-Yin deficiency. This study provides new molecular mechanism support for the clinical application of ZGW.

Clopidogrel effectively inhibits platelet aggregation in response to ADP by irreversibly binding to the platelet P2Y12 receptor through its active metabolite. However, the observed discrepancies between the pharmacokinetics (PK) and pharmacodynamics (PD) of clopidogrel present substantial challenges in individualizing of antiplatelet therapy. To address these challenges, a robust liquid chromatography-tandem mass spectrometry method has been developed to facilitate the real-time assessment of platelet P2Y12 receptor occupancy. This method has been validated in animal models, providing a reliable link between individual PK profiles and PD effects. Target receptor occupancy offers a comprehensive overview of interindividual variations in clopidogrel metabolism, regulation of P2Y12 receptor expression, and platelet turnover. Moreover, it directly correlates with the inhibitory effect on platelet aggregation. The levels of platelet P2Y12 occupancy accurately reflect the extent of clinical factors influencing the PD of clopidogrel, including dosage, drug-drug interactions (DDI), and type 2 diabetes mellitus (T2DM). As a normalized metric, platelet P2Y12 occupancy not only serves potential as a diagnostic tool for personalized clopidogrel therapy but also aids in elucidating the role of the P2Y12 signaling pathway in cases of abnormal on-treatment platelet reactivity.

Perinatal depression is a psychological disorder that occurs during pregnancy and within one year of delivery, which can seriously affect the physical and mental health of pregnant and postpartum women, as well as the cognitive and behavioral abilities of offspring, with potential multigenerational effects. Therefore, it is important to identify its potential modifiable risk factors. Phthalic acid esters (PAEs), as common environmental endocrine disruptors, can affect maternal estrogen through multiple mechanisms and are important potential modifiable risk factors for developing maternal perinatal depression. At present, studies on the correlation between PAEs and perinatal depression are still very limited, and the mechanisms by which PAEs affect perinatal depression have not been clarified. Based on existing epidemiological and toxicological studies at home and abroad, the article briefly introduced the characteristics of multiple pathways, high doses, and long-term exposure to maternal PAEs, focused on reviewing the current status of epidemiological studies, pointed out the possible associations between some specific PAEs exposure and elevated risk of perinatal depression. It also summarized the potential roles of hormone-neurotransmitter pathway, inflammation mediation, gene regulation, and other possible mechanisms in the association between exposure to PAEs and perinatal depression. The article concluded with a look at how future research on the association between exposure to PAEs and perinatal depression can be scientifically validated, with a view to providing more high-quality evidence for the scientific prevention of the onset and progression of maternal depressive symptoms.

Objective:
To investigate the mechanism of resveratrol promoting fibronectin type Ⅲ domain-containing 5 (FNDC5) degradation in skeletal muscle of male obese mice.
Methods:
Six-week-old male C57BL /6 mice were randomly divided into three groups : standard control diet ( SCD) ,high-fat diet ( HFD) and high-fat diet treated with resveratrol (HFD + RES) .HFD + RES group was intervened with resveratrol via gavage [400 mg / kg · d) ] while fed HFD for 20 weeks.The body mass,serum TG,TC,LDL-C and HDL-C levels were detected.The pathological changes in skeletal muscle were detected by HE staining.The expression of FNDC5,SIRT1,SIRT2,LC3, p62,Beclin-1,ATG5,ATG7 was assessed by immunohistochemistry,RT-PCR and Western blot respectively.
Results:
The body mass ,serum TG ,TC and LDL-C levels increased significantly ,meanwhile HDL-C levels decreased in HFD group.Lipid deposition between skeletal muscle fibers were obvious in HFD group.The immuno- histochemistry results showed that protein expression levels of SIRT1,SIRT2 and LC3 obviously decreased,while the protein levels of FNDC5 and p62 obviously increased.The expression levels of FNDC5 significantly increased, while the gene expression levels of SIRT1,SIRT2,LC3,Atg7 and Beclin-1 obviously decreased.All these responses were attenuated by treatment with RES.
Conclusion
RES has obvious effects of lipid-lowering and promoting FNDC5 degradation in skeletal muscle tissues,which may be related with SIRT1 and SIRT2-induced autophagy, thus resulting in degradation of FNDC5 .

OBJECTIVE:
To investigate the effectiveness of arthroscopic autologous iliac bone grafting with double-row elastic fixation in treatment of recurrent anterior shoulder dislocation combined with massive glenoid bone defects.
METHODS:
Between January 2018 and December 2021, 16 male patients with recurrent anterior shoulder dislocation combined with massive glenoid bone defects were treated with arthroscopic autogenous iliac bone grafting and double-row elastic fixation. The patients were 14-29 years old at the time of the first dislocation, with an average age of 18.4 years. The causes of the first dislocation included falling injury in 5 cases and sports injury in 11 cases. The shoulders dislocated 4-15 times, with an average of 8.3 times. The patients were 17-37 years old at the time of admission, with an average age of 25.1 years. There were 5 left shoulders and 11 right shoulders. The preoperative instability severity index (ISIS) score of the shoulder joint was 5.8±2.1, and the Beighton score was 4.3±2.6. The University of California Los Angeles (UCLA) score, Constant score, American Shoulder and Elbow Surgeons (ASES) score, and Rowe score were used to evaluate shoulder function, and the degree of the glenoid bone defect repair was observed based on CT after operation.
RESULTS:
All incisions healed by first intention, and no complication such as incision infection or neurovascular injury occurred. The patients were followed up 12 months. At 12 months after operation, UCLA score, Constant score, ASES score, and Rowe score all significantly improved when compared with the scores before operation ( P<0.05). CT imaging showed the degree of glenoid bone defect was significantly smaller at immediate, 6 and 12 months after operation when compared with that before operation ( P<0.05), and the bone blocks healed with the scapula, and bone fusion had occurred at 12 months.
CONCLUSION
Arthroscopic autologous iliac bone grafting with double-row elastic fixation is a safe treatment for recurrent anterior shoulder dislocation combined with massive glenoid bone defects, with good short-term effectiveness.

The globalized epidemic of the COVID-19 forced the international community to reconsider the importance and urgency of global public health in world peace and development. The authors analyzed the COVID-19 epidemic prevention and control situation in Africa, and discussed the functions and layout of China-Africa friendship hospitals from the perspective of global health governance. It was suggested that the functions of China-Africa friendship hospitals should be positioned as the high-level medical centers in Africa, regional medical and disease control linkage centers, regional health technology training centers, regional telemedicine collaboration center, and regional health policy research center.Furthermore, the layout of China-Africa friendship hospitals should respond to China′s assistance in the construction of Africa′s center for disease control and China-Africa′s cooperation plan for promoting the " one belt and one road" construction, and work together with the medical team to build a new pattern of medical integration and health care system for African disease prevention and control and medical treatment.
