ObjectiveTo explore the effect of Shenge Bushen Capsules (SBC) on sexual development in normal 3-week-old mice. MethodsThe experiment consisted of two parts. In the first part, mice were divided into four groups: The control group and the low, medium, and high-dose SBC groups (234.7, 469.4, 938.7 mg·kg-1, respectively). In the second part, mice were divided into four groups: Control group, Pseudostellariae Radix polysaccharide (PRP) group, total flavonoids group, and SBC group, all receiving a dose of 469.4 mg·kg-1. After 7 days of administration, the vaginal opening of female mice and the descent of testes and scrotum in male mice, as well as the ovarian and testicular organ indices, were observed. After 4 weeks of administration, female and male mice were housed together for 2 days, and the pregnancy rate of females was monitored. After delivery, the pregnant female mice continued receiving the treatment for 4 weeks, and the sexual development of their offspring, including vaginal opening, testicular descent, and organ indices of ovaries and testes, was observed. Serum sex hormones were measured by enzyme-linked immunosorbent assay (ELISA), and the expression of gonadotropin-releasing hormone (GnRH) and growth hormone (GH) proteins in the hypothalamus was assessed by Western blot. ResultsCompared with the control group, there was no significant effect on the vaginal opening of female mice or the descent of testes in male mice after 7 days of SBC administration. After 4 weeks of administration, the pregnancy rate in the low-dose group was significantly reduced (P<0.05), but no significant effects were observed in the other groups. The three doses of SBC did not significantly affect the ovarian or testicular organ indices, and there was no significant upregulation in the expression of GnRH or GH in the hypothalamus. The primary component of SBC, Pseudostellariae Radix polysaccharide, significantly reduced the vaginal opening in female mice after 7 days of administration (P<0.05). After 4 weeks, the serum estradiol levels of non-pregnant female mice were decreased (P<0.05), but there was no significant effect on the expression of GnRH or GH proteins in the hypothalamus of either male or female mice. Additionally, there were no significant effects on precocious puberty indicators, such as vaginal opening and testicular descent, in the offspring mice. ConclusionSBC does not significantly promote precocious puberty in young mice, and it does not have any noticeable effects on the pregnancy rate of adult mice or the sexual development of their offspring.

OBJECTIVE To investigate the ameliorative effects and potential mechanism of total secondary ginsenosides (TSG) on hypertrophic changes of primary cardiomyocytes stimulated by angiotensin Ⅱ (Ang Ⅱ). METHODS Primary cardiomyocytes were isolated from the hearts of neonatal SD rats and divided into the following groups: control group, AngⅡ group (2 µmol/L), TSG group (7.5 µg/mL), PFK-015 group [6-phosphofructo-2-kinase/fructose-2, 6-bisphosphatase 3 (PFKFB3) inhibitor, 10 nmol/L], and TSG+PFK-015 group (TSG 7.5 µg/mL+PFK-015 10 nmol/L). The surface area, protein synthesis, energy metabolism-related indicators [free fatty acid (FFA), coenzyme A (CoA), acetyl coenzyme A (acetyl-CoA)], and the expressions of glycolysis-related factors [hypoxia-inducible factor 1α (HIF-1α), glucose transporter protein 4 (GLUT-4), lactate dehydrogenase A (LDHA), pyruvate dehydrogenase kinase 1 (PDK1) and PFKFB3] in primary cardiomyocytes of each group were measured. RESULTS Compared with the control group, the surface area of primary cardiomyocytes and protein synthesis were significantly increased, the content of FFA, protein and mRNA expressions of HIF-1α, LDHA, PDK1 and PFKFB3 were significantly increased or up-regulated in the AngⅡ group, while the contents of CoA and acetyl-CoA, the protein and mRNA expressions of GLUT-4 were significantly decreased or down-regulated (P<0.05). Compared with the AngⅡ group, both TSG group and PFK-015 group showed significant improvements in these indexes, with the TSG+PFK-015 group generally demonstrating superior effects compared to either treatment alone (P<0.05). CONCLUSIONS TSG can reduce the surface area of AngⅡ-induced primary cardiomyocytes, decrease protein synthesis, and inhibit their hypertrophic changes. These effects may be related to improving energy metabolism and the inhibition of glycolysis activity.

OBJECTIVE To systematically investigate the current status and effectiveness of the standardized on-the-job training program for community clinical pharmacists in Shanghai, and to provide a scientific basis for optimizing the training scheme. METHODS A questionnaire survey was conducted to collect the data from trainees and mentor pharmacists who participated in the program between 2016 and 2024. The survey examined their basic information, evaluations of the training scheme, satisfaction with training outcomes, and suggestions for improvement. Statistical analyses were also conducted. RESULTS A total of 420 valid responses were collected, including 340 from trainees and 80 from mentor pharmacists. Before training, only 30.29% of trainees were engaged in clinical pharmacy-related work, whereas this proportion increased to 73.24% after training. Most mentor pharmacists had extensive experience in clinical pharmacy (76.25% with ≥5 years of experience) and mentoring (78.75% with ≥3 teaching sessions). Totally 65.59% of trainees and 55.00% of mentor pharmacists believed that blended training yielded the best learning outcomes. Over 80.00% of both trainees and mentor pharmacists considered the overall training duration, theoretical study time, and practical training time to be reasonable. More than 95.00% of trainees and mentor pharmacists agreed that the homework and assessment schemes were appropriate. Trainees rated the relevance of training content to their actual work highly (with an average relevance score >4.5), though they perceived the chronic disease medication therapy management module as significantly more challenging than the prescription review and evaluation module and the home-based pharmaceutical care module. The average satisfaction score of trainees and mentor pharmacists with the training effectiveness of each project was above 4 points, indicating a high overall satisfaction. Inadequate provision of teaching resources was unanimously recognized by trainees and mentor pharmacists as the key area requiring improvement. CONCLUSIONS The standardized on-the-job training program for community clinical pharmacists in Shanghai has contributed to improving pharmaceutical services in community healthcare settings. However, ongoing improvements must concentrate on content design, resource development, and faculty cultivation.

This study analyzes the legal application of a dispute over employer identification in a case of occupational heat illness caused by part-time work to clarifying matters related to employer determination in occupational disease diagnosis using a case analysis method and factual reconstruction. The analysis is based on relevant civil laws and regulations, occupational disease diagnosis laws and regulations, and jurisprudential theories. The occupational disease diagnostic institution identified the part-time employer as responsible for the patient′s heat illness, which was both reasonable and lawful. This attribution safeguarded the rights of the worker, the primary employer, and the part-time entity. In occupational disease diagnosis, attention should be paid to de facto employment relationship, and the principle of "accountability lies with the actual employer at the time of the incident" should be followed to standardize employer identification. The health administrative department has supervisory responsibilities over occupational disease diagnoses. Workers′ compensation rights can be protected through the advance payment mechanism for work-related injury insurance. It is recommended to further improve internal procedures for occupational disease diagnosis, strengthen the dissemination of relevant laws and regulations and enhance the capabilities of occupational disease diagnosis physicians, to further protect workers' occupational health and their associated legal rights.

Objective: To evaluate the efficacy of the left spermatic vein transposition to the great saphenous vein in treating left varicocele (VC) secondary to nutcracker syndrome (NCS). Methods: Clinical data of 8 patients treated during Feb.2020 and Feb.2023 in our hospital were retrospectively analyzed.A meticulous preoperative evaluation of the vascular status of the spermatic vein and the great saphenous vein was performed using color Doppler ultrasound.A spermatic vein-great saphenous vein shunt surgery was performed in patients who were strictly selected.The clinical symptoms and hemodynamics of renal vein were compared before and after operation. Results: The median age of patients was 23.5(18-33) years.There was a notable reduction in post-exercise scrotal and lower back pain in all patients,and the score of scrotal pain decreased to 0 in 7 patients. The median quantification of urinary protein was 352.8(54.4-687.3) mg prior to surgical intervention,which significantly diminished to 125.5(25.9-255.1) mg 6 months after operation.Notably,3 cases of preoperative positive urine occult blood tests were undetectable in the subsequent postoperative assessments.The median peak blood flow velocity at the site of stenosis in the left renal vein measured at 74.4(48.7-117.6) cm/s preoperatively,subsequently reduced to 45.1(25.5-61.2) cm/s postoperatively.During the 6-month follow-up,no recurrence of varicocele,vascular anastomotic stenosis or thrombosis were observed. Conclusion: Our research indicates that spermatic vein to great saphenous vein bypass is safe and feasible in the treatment of left varicocele secondary to nutcracker syndrome for strictly selected patients,which can effectively alleviate renal vein congestion without significant complications.

Aquatic organisms can secrete biomacromolecules through specialized organs, tissues, or structures, enabling adhesion to underwater material surfaces and leading to severe biofouling issues. This phenomenon adversely impacts aquatic ecosystem health and human activities. Biofouling has emerged as an emerging global environmental challenge. Adhesion serves as the foundation of biofouling, representing a critical step toward a comprehensive understanding of the adhesion mechanisms of aquatic organisms. Biomacromolecules, including proteins, lipids, and carbohydrates, are the primary functional components in the adhesive substances of aquatic fouling organisms. Research indicates that these biomacromolecules exhibit diversity in types and characteristics across different aquatic organisms, yet their adhesion mechanisms show unifying features. Despite significant progress, there remains a lack of comprehensive reviews on the adhesion mechanisms mediated by biomacromolecules in aquatic fouling organisms, particularly on the roles of lipids and carbohydrates. Through a comprehensive analysis of existing literature, this review systematically summarizes the mechanistic roles of three classes of macromolecules in aquatic biofouling adhesion processes. Proteins demonstrate central functionality in interfacial adhesion and cohesion through specialized functional amino acids, conserved structural domains, and post-translational modifications. Lipids enhance structural stability via hydrophobic barrier formation and antioxidative protection mechanisms. Carbohydrates contribute to adhesion persistence through cohesive reinforcement and enzymatic resistance of adhesive matrices. Building upon these mechanisms, this review proposes four prospective research directions: optimization of protein-mediated adhesion functionality, elucidation of lipid participation in adhesion dynamics, systematic characterization of carbohydrate adhesion modalities, and investigation of macromolecular synergy in composite adhesive systems. The synthesized knowledge provides critical insights into underwater adhesion mechanisms of aquatic fouling organisms and establishes a theoretical foundation for developing mechanism-driven antifouling strategies. This work advances fundamental understanding of bioadhesion phenomena while offering practical guidance for next-generation antifouling technology development.

Psoriasis is a chronic inflammatory skin disease with a polygenic genetic background. Its etiology remains unclear, and its pathogenesis is complex and refractory, collectively posing significant challenges in its treatment and greatly affecting the physical and mental health of patients. With the advantages of multi-target and multi-pathway treatment, traditional Chinese medicine has shown unique efficacy and value in the diagnosis and treatment of psoriasis. Modern doctors have a lot of discussion on psoriasis, and most of them tend to treat the disease by solving disorders of the blood system. They think that the disease is closely related to the "heat in the blood". Combining the clinical characteristics and accompanying symptoms of psoriasis, this article traced the causes of "heat in the blood" in psoriasis and believed that multiple internal and external factors have prevented the smooth circulation of Qi. Yang Qi Fuyu (stagnation) and transformation into heat and toxicity is the source of "heat in the blood" in psoriasis. Furthermore, it was proposed that "Fuyu" is the core pathogenesis of psoriasis. The etiology of "Fuyu" is complex, such as external wind and cold pathogens, emotional injuries, internal accumulation of dampness, and deficiency of healthy Qi, all of which can disrupt the ascending and descending movement of Qi, impede the circulation of Qi and fluids, close the pores and skin texture, and subsequently lead to stagnation. Based on the above understanding, "resolving stagnation" is crucial for treating the disease. Many doctors have explored the treatment ideas of psoriasis from the perspectives of dispelling wind, warming cold, regulating Qi, eliminating dampness, tonifying deficiency, and external treatment, aiming to remove the causes, promote the circulation of Qi and fluids, and resolve stagnation and heat. Clinical studies have shown that the therapies can relieve clinical symptoms, reduce recurrence rate, and improve quality of life, which also have good safety in the treatment of psoriasis. This article discussed the treatment of psoriasis from the perspective of "Fuyu", enriching the understanding of TCM regarding the etiology and pathogenesis of psoriasis. It is aiming to serve as an effective supplement to the "treating by solving disorders of the blood system" approach and provide a reference for clinical diagnosis and treatment of psoriasis.
