Objective To compare the clinical outcomes of subxiphoid robot-assisted thoracoscopic surgery (SRATS) and intercostal robot-assisted thoracoscopic surgery (IRATS) in the treatment of anterior mediastinal tumors. Methods A retrospective analysis was conducted on patients with anterior mediastinal tumors who underwent robot-assisted surgery in the Department of Thoracic Surgery, Gansu Provincial Hospital, from May 2020 to July 2022. According to the surgical approach, patients were divided into an SRATS group and an IRATS group. Perioperative data were compared between the two groups. Results A total of 87 patients were included. There were 41 patients in the SRATS group [23 males, 18 females; mean age, (44.51±11.28) years] and 46 patients in the IRATS group [21 males, 25 females; mean age, (46.67±8.76) years]. Compared with the IRATS group, the SRATS group had significantly less intraoperative blood loss [(24.41±6.67) mL vs. (37.93±9.23) mL, P<0.001], shorter postoperative drainage duration [(1.73±0.59) days vs. (2.54±0.50) days, P<0.001], lower postoperative drainage volume [(94.46±34.08) mLvs. (116.72±24.90) mL, P=0.001], lower visual analogue scale (VAS) pain scores on postoperative day 1 [(3.66±0.76) points vs. (4.15±0.84) points, P=0.005] and day 3 [(2.41±0.59) points vs. (2.89±0.82) points, P=0.003], shorter postoperative hospital stay [(4.12±0.81) days vs. (4.98±1.02) days, P<0.001], and lower hospitalization costs [(4.51±0.65) ten thousand yuan vs. (4.86±0.68) ten thousand yuan, P=0.020]. There were no statistical differences between the two groups in operative time or incidence of postoperative complications (P>0.05). Conclusion Both SRATS and IRATS are safe and effective for the treatment of anterior mediastinal tumors. However, SRATS is less invasive and more conducive to enhanced postoperative recovery.

By consulting ancient and modern literature, this article systematically reviews and verifies the historical evolution of the herbal medicine known as Baijiang across various dimensions, including name, origin, scientific name verification, medicinal parts, production area, quality, harvesting and processing, as well as its nature, taste, and therapeutic effects, in order to provide a reference for the development and utilization of famous classical formulas containing Patriniae Herba. Patriniae Herba has a long history of use. It derives its name from the distinctive musty odor of its roots, which resembles spoiled soy sauce. However, due to its alias Kucai, there has been much confusion with other plants. Since the Ming dynasty, various plants have been used interchangeably as Baijiang. Herbal textual research showed that Patriniae Herba was first recorded in Shennong Bencaojing, and throughout history, Baijiang has been recognized as its standard name, though it has also been known by alternative names such as Luchang, Lujiang, and Suanyi. The main sources used throughout the ages were Patrinia scabiosaefolia or P. villosa, which is consistent with the 1977 edition of the Pharmacopoeia of the People's Republic of China. However, while the roots were traditionally used medicinally, the whole plant is now more commonly used in modern practice. In addition, the whole plants of Thlaspi arvense from the Cruciferae family and Sonchus brachyotus from the Compositae family are commonly used as regional substitutes for Baijiang. According to ancient records, Patriniae Herba was primarily found in Jiangxia(present-day eastern Hubei province) and Jiangdong(the region south of the lower reaches of the Yangtze River), but modern literature shows that it is distributed throughout the country without a distinct geographical origin. In ancient times, the roots were harvested in August and sun-dried, today, the whole plant is typically dug up in summer or autumn and sun-dried. In recent times, the quality has been summarized as being best when the roots are long, the leaves are abundant and green, and the aroma is strong. Regarding the processing, ancient methods often involved baking(drying over fire), while modern methods typically involve removing impurities, washing, and then cutting and drying the segments. The effects of Patriniae Herba are to clear heat and detoxify, eliminate blood stasis and drain pus. During the Han and Northern and Southern dynasties, it was used to treat skin diseases caused by heat, abscesses, postpartum diseases, and rheumatism, during the Five dynasties period, its therapeutic applications expanded to include diseases of the five senses, and by the modern era, conditions such as neurasthenia and insomnia were added. Regarding its properties and taste, it was recorded as bitter and neutral during the Han dynasty. By the Tang dynasty, it was slightly cold, with a taste of acrid and bitter. During the Yuan and Ming dynasties, it was mostly slightly cold and neutral, with a bitter and salty taste. In the Qing dynasty and modern times, it was mostly bitter and neutral, and in contemporary times, it has evolved to a taste of acrid, bitter, and cool. Based on the results of this study, it is recommended that when developing and utilizing famous classical formulas containing Patriniae Herba, one should select the entire herb of the historically mainstream sources, P. scabiosaefolia or P. villosa from the Valerianaceae family, and choose the processing method according to the prescription requirements. It is recommended to use raw products without specific requirements.

OBJECTIVE To compare the efficacy, safety, and cost-effectiveness of two different formulations of short-acting recombinant human growth hormone (rhGH) in the treatment of patients with short stature. METHODS Data from patients with short stature treated with short-acting rhGH at the Leshan People’s Hospital from August 2016 to June 2023 were collected. Patients were divided into powder formulation group and aqueous formulation group based on the rhGH formulation used. The changes in growth-related efficacy indicators and the occurrence of adverse drug reactions were compared between two groups after 12 months of treatment; cost-effectiveness analysis and sensitivity analysis were used to compare the cost per unit of effect achieved; subgroup analysis was performed by dividing the patients into growth hormone deficiency (GHD) subgroup and idiopathic short stature (ISS) subgroup based on clinical diagnosis. RESULTS After 12 months of treatment, the height and the levels of insulin-like growth factor-1 and insulin-like growth factor binding protein-3 in serum in aqueous formulation group and powder formulation group were significantly increased compared to before treatment (P<0.001), but there was no statistically significant difference in the changes of the above indicators between the two groups(P>0.05). The analysis results of GHD and ISS subgroups were consistent with the overall population. In the overall population, the cost-effectiveness ratio of powder formulation group (2 582 yuan/cm) was significantly better than that of aqueous formulation group (6 729 yuan/cm), with a statistically significant difference (P<0.001), and the result was consistent in the GHD and ISS subgroups as well as in the sensitivity analysis. No serious adverse drug reactions occurred in either powder formulation or aqueous formulation group, and there was no statistically significant difference in the incidence of various adverse reactions between two groups (P>0.05). CONCLUSIONS Short-acting rhGH powder and aqueous formulations have equivalent efficacy and safety, but the powder formulation has greater economic advantages.

This article systematically analyzes the historical evolution of the name, origin, medicinal parts, harvesting and processing, and other aspects of Manjiao and Zanthoxyli Radix by referring to the herbal medicine, medical books, prescription books and other documents of the past dynasties, combined with the relevant modern research materials, in order to provide a basis for the development of famous classical formulas containing the two medicinal materials. According to the herbal textual research, Manjiao was first recorded in Shennong Bencaojing of the Han dynasty with aliases such as Zhujiao, Goujiao and Zhijiao. Throughout history, Manjiao was sourced from the stems and roots of Zanthoxylum armatum in the Rutaceae family, and its leaves and fruits can also be used in medicine. The traditional recorded production area was mainly in Yunzhong(now Tuoketuo region in Inner Mongolia), with mentions in Zhejiang, Hunan, Fujian, Guangdong, Guangxi, Yunnan, Taiwan, and other provinces. Presently, this species is distributed from the south of Shandong, to Hainan, Taiwan, Tibet and other regions. The roots can be harvested year-round, while the fruits are harvested in autumn after maturity. In ancient times, the roots and stems were mostly used for brewing or soaking in wine, whereas nowadays, the roots are often sliced and then used as a raw material in traditional Chinese medicine, and the fruits should be stir-fried before use. Manjiao has a bitter taste and warm property, and was historically used to treat wind-cold dampness, joint pain, limb numbness, and knee pain. Modern researches have summarized its effects as dispelling wind, dispersing cold, promoting circulation, and relieving pain, and it is used for treating rheumatoid arthritis, toothache, bruises, as well as an anthelmintic. Zanthoxyli Radix initially known as Rudi Jinniugen, recorded in Bencao Qiuyuan of the Qing dynasty, with the alternate name of Liangbianzhen. In recent times, it is more commonly referred to as Liangmianzhen, sourced from the dried roots of Z. nitidum of the Rutaceae family, mainly produced in Guangxi and Guangdong. It can be harvested throughout the year, cleaned, sliced, and dried after harvesting. Zanthoxyli Radix is pungent, bitter, warm and slightly toxic, with the functions of promoting blood circulation, removing stasis, relieving pain, dispelling wind, and resolving swelling. Based on the results of herbal textual research, it is clarified that the ancient Manjiao and the modern Zanthoxyli Radix are not the same species. This article corrects the mistaken belief of by previous scholars that Zanthoxyli Radix is the same as ancient Manjiao, and suggests that formulas described as Manjiao should use Z. armatum as the medicinal herb, while those described as Liangmianzhen or Rudi Jinniu should use Z. nitidum. The processing was performed according to the processing requirements prescribed in the formulas, otherwise, the raw products are recommended for use.

Objective:
To investigate the epidemic characteristics and trends in incidence of pulmonary tuberculosis (PTB) in Wenzhou City, Zhejiang Province from 2010 to 2024, so as to provide the basis for improving PTB prevention and control strategies.
Methods:
The PTB data in Wenzhou City from 2010 to 2024 were captured from the Surveillance System of China Information System for Disease Control and Prevention. Descriptive epidemiological methods were applied to analyze the characteristics across different genders, age, and regions. The average annual percent change (AAPC) was used to evaluate the trend in PTB incidence.
Results:
A total of 73 706 PTB cases were reported in Wenzhou City from 2010 to 2024, with an average annual reported incidence of 52.92/100 000. The reported incidence of PTB decreased from 75.33/100 000 in 2010 to 35.47/100 000 in 2024, showing a significant overall downward trend (AAPC=-5 .287%, P<0.05). The average annual reported incidence of PTB was higher in males than in females (70.45/100 000vs. 33.41/100 000, P<0.05). The trends in reported incidence for both males and females were generally consistent with the overall population, showing declining trends (AAPC=-4.992% and -6.112%, both P<0.05). The group aged ≥65 years had the highest average annual reported incidence of PTB at 91.73/100 000. From 2010 to 2024, significant declining trends were observed in the groups aged 15-<25, 25-<35, 35-<45, and 45-<55 years (AAPC=-8.599%, -7.975%, -9.007%, and -5.104%, all P<0.05). The average annual reported incidences of PTB in Taishun County, Longwan District, and Yongjia County were higher, at 81.08/100 000, 75.31/100 000, and 64.68/100 000, respectively. Except for Dongtou District, Pingyang County, and Taishun County, the reported incidences in all other counties (cities, districts) showed declining trends from 2010 to 2024, with AAPC values ranging from -9.056% to -3.791% (all P<0.05).
Conclusions
The reported incidence of PTB in Wenzhou City from 2010 to 2024 showed an overall declining trend, varying in genders, age, and regions. Males and individuals aged ≥65 years were the key populations for prevention and control. Taishun County, Longwan District, and Yongjia County were high-incidence areas.

This article systematically analyzes the historical evolution of the name, origin, medicinal parts, harvesting, processing and others of Chrysanthemi Indici by referring to the herbal medicine, medical books, prescription books and other documents of the past dynasties, combined with the relevant modern research materials, in order to provide a basis for the development of famous classical formulas containing this medicinal herb. According to the research, Chrysanthemi Indici was first recorded under the name Kuyi in Bencao Jingjizhu, with aliases such as Yeshanju, Huangjuzai and Lubianju. The botanical source of Chrysanthemi Indici throughout history was Chrysanthemum indicum of the Asteraceae family. It is now distributed in most areas of China, and since the Qing dynasty, the product from Suichang, Zhejiang has been highly regarded. The whole plant can be used as medicine. According to the natural growth laws, the roots were collected in the first lunar month, leaves in the third, stems in the fifth, flowers in the ninth, and fruits in the eleventh, all of which were dried in the shade. In modern times, Chrysanthemi Indici is harvested during their initial blooming in autumn and winter. Since Bencao Gangmu listed Chrysanthemi Indici as a single medicinal material and clarified that all parts have medicinal value, ancient herbal texts began to record the independent medicinal use of Chrysanthemi Indici Flos, and the use of flowers as medicine has become mainstream. In modern times, the quality of Chrysanthemi Indici Flos is summarized to be best when they are dry, yellow, complete, and fragrant. Because Chrysanthemi Indici has a bitter and pungent taste, and is warm, it can eliminate and disperse, often using the power of alcohol to reach and ascend, and is commonly used to treat carbuncles, boils, and scrofula, with consistent properties and effects throughout ancient and modern times. Based on the research results, it is suggested that Chrysanthemi Indici involved in the formulas can be used as C. indicum, which can be used according to the medicinal parts labeled in the original formulas and the requirements of processing, while those without clear medicinal parts and requirements of processing should be used as the whole plant of the dried raw products.

OBJECTIVES:
Verrucous epidermal nevus (VEN), seborrheic keratosis (SK), verruca plana (VP), verruca vulgaris (VV), and nevus sebaceous (NS) are common verrucous proliferative skin diseases with similar clinical appearances, often posing diagnostic challenges. Dermoscopy and reflectance confocal microscopy (RCM) can aid in their differentiation, yet their specific features under these tools have not been systematically described. This study aims to summarize and analyze the dermoscopic and RCM features of VEN, SK, VP, VV, and NS.
METHODS:
A total of 121 patients with histopathologically confirmed verrucous proliferative skin diseases were enrolled. Dermoscopy and RCM imaging was used to observe and analyze the microscopic features of these conditions.
RESULTS:
Under dermoscopy, the 5 diseases displayed distinct characteristics: VEN typically showed gyriform structures; SK was characterized by gyriform structures, comedo-like openings, and milia-like cysts; VP and VV featured dotted vessels and frogspawn-like structures; NS presented as brownish-yellow globules. RCM revealed shared features such as hyperkeratosis and acanthosis across all 5 diseases. Specific features included gyriform structures and elongated rete ridges in VEN; pseudocysts and gyriform structures in SK; evenly distributed ring-like structures in VP; vacuolated cells and papillomatous proliferation in VV; and frogspawn-like structures in NS.
CONCLUSIONS
These 5 verrucous proliferative skin conditions exhibit distinguishable features under both dermoscopy and RCM. The combination of these 2 noninvasive imaging modalities holds significant clinical value for the differential diagnosis of verrucous proliferative skin diseases.

N6-Methyladenosine (m6A) modification is a crucial post-transcriptional regulatory mechanism and the most abundant and highly conserved RNA epigenetic modification in eukaryotes. Previous studies have indicated the involvement of m6A modification in various tissue regeneration processes, including liver regeneration. Vir-like m6A methyltransferase associated protein (VIRMA) is an m6A methyltransferase with robust methylation capability. However, its role in liver regeneration remains poorly understood. In this study, we generated liver-specific Virma knockout mice using the Cre-loxP system and investigated the biological functions of VIRMA in liver regeneration using both the Associating Liver Partition and Portal vein Ligation for Staged Hepatectomy (ALPPS) mouse model and the carbon tetrachloride (CCl4) mouse model. The expression level of VIRMA was rapidly up-regulated after ALPPS surgery and gradually down-regulated during liver repair. Virma deficiency significantly impaired liver regeneration capacity and disrupted cell cycle progression. Methylated RNA immunoprecipitation sequencing (MeRIP-seq) analysis revealed that Shq1 is an effective downstream target of VIRMA-mediated m6A modification. The upregulation of Shq1 enhanced the proliferation ability of cells, which was attenuated by the specific AKT inhibitor ipatasertib. Supplementation of Shq1 in vivo alleviated the liver cell proliferation inhibition caused by Virma deficiency. Furthermore, the m6A-binding protein heterogeneous nuclear ribonucleoprotein a2b1 (HNRNPA2B1) enhanced the mRNA stability of Shq1. Mechanistically, Virma deficiency resulted in decreased m6A modification on Shq1 mRNA, leading to reduced binding ability of m6A-binding protein HNRNPA2B1 with Shq1, thereby decreasing the mRNA stability of Shq1 and reducing its protein expression level. Downregulation of Shq1 inhibited the PI3K/AKT pathway, thereby suppressing cell proliferation and cell cycle progression, ultimately impeding liver regeneration. In summary, our results demonstrate that VIRMA plays a critical role in promoting liver regeneration by regulating m6A modification, providing valuable insights into the epigenetic regulation during liver regeneration.
