Sangjuyin， as a pungent and cooling agent with precise therapeutic effect， is a classic pungent formula for cooling relief of the epidermis， which is highly respected by medical practitioners. This formula is from the Wenbing Tiaobian written by WU Jutong in the Qing dynasty， on the basis of which subsequent medical practitioners have made additions and subtractions to apply it. The authors used the bibliometric method to systematically organize the medical books from the Qing dynasty and the Republic of China and modern literature to analyze the composition， concoction， decoction， efficacy， and previous and modern application of Sangjuyin. After examination， the drug base of this formula is basically clear. Armeniacae Semen Amarum is the dried mature seeds of Armeniaca vulgaris， family Rosaceae. Forsythiae Fructus is the dried fruit of Forsythia suspensa， family Mulleinaceae. Menthae Haplocalycis Herba is the dried above-ground part of Mentha haplocalyx， family Labiatae. Mori Folium is the dried leaves of Morus alba， family Moraceae. Chrysanthemi Flos is the dried head of Chrysanthemum morifolium， family Asteraceae. Platycodonis Radix is the dried root of Eryngium grandiflorum， family Eryngium. Glycyrrhizae Radix et Rhizoma is the dried root and rhizome of Glycyrrhiza uralensis of the Leguminosae family， and Phragmitis Rhizoma is the fresh or dried rhizome of Phragmites communis of the Gramineae family. It is recommended that the eight drugs be used in raw form as medicine. The dosage and method of decoction were converted into a modern single dosage of 7.46 g Armeniacae Semen Amarum， 5.60 g Forsythiae Fructus， 2.98 g Menthae Haplocalycis Herba， 9.33 g Mori Folium， 3.73 g Chrysanthemi Flos， 7.46 g Platycodonis Radix， 2.98 g Glycyrrhizae Radix et Rhizoma， and 11.19 g Phragmitis Rhizoma， with 400 mL water added， and the solution was boiled to obtain 200 mL， taken twice a day. Sangjuyin has the efficacy of dispersing wind and clearing heat， promoting lung and relieving cough， and it is used for treating the initial onset of wind-warmth and the evidence of evil spirits in the lungs and collaterals. Modern research has shown that Sangjuyin is often used in the treatment of cough， pneumonia， rhinitis， and other respiratory diseases， and the results of this study provide a reference for the later development of Sangjuyin.

Erchentang is a classic formula widely used by medical practitioners throughout history. In this paper，ancient and modern literature of Erchentang were collected， and bibliometrics was employed to analyze its historic evolution，prescription meaning，herbs origin， processing method，preparation methods， and clinical application. A total of 84 pieces of data were collected， and 58 pieces of data involving 53 ancient medical Chinese books were screened， sorted， and processed. Combined with research of modern scholars，the research has found that the Erchentang originated from the Taiping Huimin Huiye Shijie Fang compiled by the Imperial Medical Bureau of the Song Dynasty. The basic information about the origin of the drugs is quite clear. Pinelliae rhizoma in the formula is the dried tuber of Pinellia ternata. Citri exocarpium rubrum is the dried mature peel of Citrus reticulata and its cultivated varieties， with the inner white membrane removed. Poria is the whitest dry sclerotia of Poria cocos； Glycyrrhizae radix et rhizoma is the dried root and rhizome of the Glycyrrhiza uralensis. The dosage is 5.70 g Pinelliae rhizome and Citri exocarpium rubrum， 3.43 g Poria， and 1.69 g Glycyrrhizae radix et rhizoma praeparata cum melle. During the decoction process， the above-mentioned herbs should be chopped， with 300 mL water， 7 g ginger in thick slices， and 2 g Mume fructus added， and it was then simmered together to 180 mL. After removing the medicinal residue， it can be taken warmly. Erchentang has the effect of drying dampness and resolving phlegm， regulating Qi and harmonizing the middle. It can be used in treating the syndrome of phlegm and dampness，as well as symptoms such as frequent cough，white phlegm，fullness in chest and diaphragm，nausea and vomiting，limb drowsiness，anorexia，dizziness，palpitations，white and greasy tongue coating， and slippery pulse. The above results provide reference for future research and development of Erchentang.

Zoledronic acid (ZA), a nitrogen-containing bisphosphonate with established clinical utility in osteoporosis management, exhibits emerging antitumor potential in estrogen receptor-positive breast cancer. However, the molecular mechanisms underlying its nonapoptotic anticancer effects remain poorly characterized. This study revealed that ZA induced ferroptosis in ER+ breast cancer cells through dual suppression of cystine-glutamate antiporter SLC7A11 and glutathione peroxidase 4 (GPX4), key repressors of ferroptosis. Pharmacological inhibition of ferroptosis using Ferrostatin-1 significantly attenuated ZA-induced cytotoxicity, while combinatorial treatment with the GPX4 inhibitor RSL3 synergistically enhanced lipid peroxidation and cell death. Mechanistically, ZA activated the Hippo-YAP signaling pathway, promoting YAP phosphorylation, proteasomal degradation, and cytoplasmic retention, thereby silencing SLC7A11 and GPX4. We established a novel metabolic vulnerability in hormone-responsive malignancies.These findings position ZA as a bifunctional ferroptosis inducer in ER+ breast cancer, offering a promising strategy to overcome endocrine resistance.

Objective:To investigate the association between blood selenium levels and sex hormones in Chinese men aged 18-79 years.Methods:Data were derived from the China National Human Biomonitoring survey conducted in 2017-2018, with a final sample size of 5 414 men. General demographic characteristics, behavioral habits, and dietary frequency were collected through questionnaires and physical examinations. Fasting blood samples were collected to measure blood lead, serum testosterone, and estradiol levels. Complex sampling linear regression models were used to analyze the associations between blood selenium levels and testosterone, estradiol, and the testosterone/estradiol ratio, adjusting for confounding factors including age, education level, marital status, smoking status, alcohol consumption, seafood intake, soy product intake, protein supplement intake, BMI, and diabetes status.Results:The mean age of the 5 414 participants was (46.85±27.91) years; 4 774 (91.65%) were of Han ethnicity and 4 505 (86.68%) were married. The median ( Q1, Q3) blood selenium concentration in men was 97.80 (80.64, 116.99) μg/L. After adjusting for confounding factors, the complex sampling linear regression model revealed negative associations between blood selenium levels and both testosterone levels and the testosterone/estradiol ratio, with a significant linear trend ( Ptrend<0.05). Compared with the Q1 group, the β (95% CI) values for testosterone in the Q2, Q3, and Q4 groups were -0.02 (-0.06 to 0.02), -0.03 (-0.08 to 0.01), and -0.06 (-0.09 to -0.02), respectively. Similarly, the β (95% CI) values for the testosterone/estradiol ratio in the Q2, Q3, and Q4 groups were -0.01 (-0.03 to 0.02), -0.01 (-0.04 to 0.04), and -0.03 (-0.06 to -0.01), respectively. Subgroup analysis indicated stronger associations between blood selenium levels and testosterone/estradiol levels in non-smoking and obese men (BMI≥28 kg/m2). Conclusion:Blood selenium levels are negatively associated with testosterone levels and the testosterone/estradiol ratio in Chinese adult males.

Shengjiangsan is a classic formula for treating warm diseases with wide clinical application and accurate efficacy. There are different opinions on the origin of this formula and lacks key information research on this formula. Therefore， in this study， we conducted systematic research into the historic origin， composition， and other key information of this Shengjiangsan. Results showed that Shengjiangsan has different versions， with "Neixian Fufang"， "Jiawei Jianghuangwan"， "Peizhensan"， and "Taijiwan" being the same formula with different names. Shengjiangsan was first recorded as "Neixian Fufang" in Wanbing Huichun written by GONG Tingxian from the Ming dynasty， inherited and developed by YANG Lishan from Qing dynasty， and has been passed down to modern times. Pills and powder are two main forms of Shengjiangsan， and powder has become more popular nowadays. According to the measurement system of Ming and Qing dynasties， the recommended dosage and usage of Shengjiangsan are as follows. For the pill version of Shengjiangsan， Bombyx Batryticatus of 74.6 g， Curcumae Longae Rhizoma of 9.325 g， Cicadae Periostracum of 9.325 g， and Rhei Radix et Rhizoma of 149.2 g were processed into pills for preparation. Single dosage is Bombyx Batryticatus of 1.15 g， Curcumae Longae Rhizoma of 0.14 g， Cicadae Periostracum of 0.14 g， and Rhei Radix et Rhizoma of 2.3 g， with halved dosage applied for children. For the powder version of Shengjiangsan， the dosage varied in accordance with the severity of the disease. Bombyx Batryticatus of 1.84 g， Curcumae Longae Rhizoma of 0.28 g， Cicadae Periostracum of 0.92 g， and Rhei Radix et Rhizoma of 3.68 g were processed into powder for patients with mild symptoms. Bombyx Batryticatus of 2.48 g， Curcumae Longae Rhizoma of 0.37 g， Cicadae Periostracum of 1.23 g， and Rhei Radix et Rhizoma of 4.91 g were processed into powder for patients with severe symptoms. Bombyx Batryticatus of 3.68 g， Curcumae Longae Rhizoma of 1.84 g， Cicadae Periostracum of 0.55 g， and Rhei Radix et Rhizoma of 7.36 g were processed into powder for patients with critical conditions. In this formula， four herbs were ground to fine powder. For patients with mild symptoms， the whole formula was divided into four dosages， and each dosage weighed 6.71 g. The 200 mL yellow rice wine and 18.65 g honey were added， and the solution was stirred and taken cold till full recovery. For patients with severe symptoms， the whole formula was divided into three dosages， and each weighed 8.95 g. 300 mL yellow rice wine and 27.98 g honey were added， and the solution was stirred and taken cold. For patients with critical conditions， the whole formula was divided into two dosages， and each weighed 13.43 g. 400 mL yellow rice wine and 37.3 g honey were added， and the solution was stirred and taken cold. Shengjiangsan has the effect of ascending lucidity and descending turbidity， dissipating wind， and clearing heat. It is specialized in treating severe heat in exterior， interior， and triple energizers in warm diseases and has a wide modern clinical application. In this study， the historic evolution and key information of Shengjiangsan were reviewed and analyzed， and the key information table of Shengjiangsan was attached， serving as a reference for scholars' research and a theoretical basis for its market transformation.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective:Medial sural artery perforator flap (MSAPF) was applied to aesthetically reconstruct wounds in foot, and clinical outcome of this surgical method was explored.Methods:A retrospective analysis was conducted on the data of 10 patients who underwent the surgery of transfer of free MSAPF in reconstruction of foot wounds in the Department of Foot and Ankle Surgery, Xuzhou Renci Hospital from January 2020 to January 2023. The patients were 6 males and 4 females, aged 21 to 52 years, with an average of 42.5 years. The soft tissue defects of the injuries were at 2.0 cm × 4.0 cm to 3.5 cm × 6.0 cm in size, with deep tissues exposure down to the base of wound. MSAPF was used for aesthetic reconstruction of the wounds. The surgical procedures were: (1) The flap was thinned under a microscope and only the subdermal vascular network was kept. (2) Vascular pedicle of the flap was taken as long as possible and had it anastomosed with the proximal dorsal foot artery and vein through a subcutaneous tunnel. (3) Allg?wer-Donati method was applied to suture the skin of flap. (4) Donor site was directly closed in surgery. All patients were entered in the scheduled postoperative follow-up at the outpatient clinic of the surgeon who performed the surgery to evaluate the postoperative effect and observe the survival of flaps. Maryland foot function score and British Medical Research Council (BMRC) sensory function score were used to assess the recovery of flap and limb function.Results:The flaps completely survived, and all the donor and recipient sites had primary healing. All of the 10 patients were included in the postoperative follow-up which lasted 8 to 15 months, with an average of 12 months. The flaps from foot featured a pleasing appearance, with good elasticity and wear-resistant. All patients were satisfied and able to walk normally and bear weight without an occurrence of flap ulceration. At the final follow-up, the therapeutic effect was evaluated according to the Maryland scoring system and achieved the scores at 91 to 98, with 95.6 in average. Nine patients were rated as excellent and 1 as good. The sensory grading by BMRC for the flaps was as follows: the flap sensation of the sutured nerve group recovered to S 3 in 3 cases and S 4 in 2 cases, while the non sutured nerve group only recovered protective sensation, S 2 in 3 cases and S 2+ in 2 cases. Conclusion:By applying MSAPF aesthetics to treat foot wounds, a good appearance has been achieved, with good functional recovery and satisfactory therapeutic effects.
