ObjectiveTo explore the changes in color， odor and chemical components during wine-processing of Chuanxiong Rhizoma（CR）， identify differential markers， and provide a basis for standardizing the process and establishing quality standards. MethodsFifteen batches of CR samples from 4 producing areas were collected. Colorimeter and electronic nose were used to detect the color changes and odor components of CR before and after wine-processing. Multivariate statistical methods including partial least squares-discriminant analysis（PLS-DA）， principal component analysis（PCA）， discriminant factor analysis（DFA） and Fisher discriminant analysis were applied to identify wine-processed CR at different processing stages and establish discriminant models， and differential components were screened out based on variable importance in the projection（VIP） value1. Then， high performance liquid chromatography（HPLC） was employed to detect the content changes of four components（ferulic acid， senkyunolide I， senkyunolide A and ligustilide） during the processing stages. ResultsThe differences of wine-processed CR at various stages were primarily reflected in color parameters L^*（brightness value）， a^*（red-green value） and b^*（yellow-blue value）. Based on chromaticity differences， the color reference ranges were established for moderately processed CR， including L^* of 46.75-48.24， a^* of 5.37-6.07 and b^* of 20.32-21.70. In odor analysis， DFA revealed significant differences among processing stages， and 11 odor markers were identified， with four differential markers（4-hydroxy-3-butylphthalide， isopropyl butyrate， L-limonene and 1-methoxyhexane） based on VIP values. HPLC results showed that there was no significant difference of the four components except for ligustilide in wine-processed CR at different stages. ConclusionThis study achieved rapid identification of wine-processed CR with different processing degrees by electronic sensory technology and differential component content detection， with discrimination accuracy rates of 92.4% and 93.272% for color and odor， respectively. This paper also established the reference ranges of main colorimetric parameters for wine-processed CR at different stages， and four differential components were screened out， providing a basis for standardizing the processing of wine-processed CR and establishing quality standards for this decoction pieces.

A 66-year-old female patient was admitted to the Emergency Surgery Department of Shaanxi Provincial People’s Hospital in November 2019 due to sudden high fever accompanied by skin redness and pain in the whole abdomen and perineum. After systemic anti-infection and local drainage of perineum area, the patient was discharged with improved symptoms. However, the symptoms recurred 12 days later and the patient was admitted to emergency surgery again. After the treatment, the effect was poor, and the drainage volume was maintained at 100-150 ml/d. Multidisciplinary consultation was organized and after detailed medical history questioning by plastic surgeons, it was confirmed that the patient had received polyacrylamide gel (PAAG) injection for breast augmentation 30 years ago and was therefore transferred to plastic surgery for systematic treatment. According to the patient’s clinical manifestations, bilateral breast and abdominal wall imaging result and medical history, PAAG was diagnosed as chronic non-specific inflammation of the whole abdominal wall and perineum after breast augmentation. PAAG was removed by infra mammary fold incision, combined with liposuction tube vacuum suction and whole abdominal fascial space debridement and lavage drainage. Pathological examination of capsule tissue after the operation showed foreign body granulomatous inflammation, consistent with chronic non-specific inflammatory changes after PAAG injection. The patient recovered well after surgery and was discharged 7 days later. During the 6-year follow-up, the patient no longer experienced related symptoms and accepted the current breast shape. The patient is currently under continuous follow-up observation. The treatment process of this patient indicates that a detailed medical history, comprehensive physical examination, and clear diagnosis are key prerequisites for ensuring correct treatment. Ultrasound and MRI are important methods for assessing the residual and distribution of fillers. For injection augmentation surgeries, regular follow-ups after surgery are necessary.

Objective:To investigate the role of miR-182-5p regulated primary cilia loss on migration of TPC-1 in papillary thyroid cancers(PTC).Methods:Ten cases of PTC and adjacent tissues were collected from the First Hospital of Lanzhou University, The expression of miR-182-5p in PTC tissue and TPC-1 cells was detected by qPCR, and the frequency of primary cilia was detected by immunofluorescence; Overexpressing miR-182-5p, the migrated number of TPC-1 was detected by Transwell assay; Interfering TPC-1 with siRNA-IFT88, the migrated number of TPC-1 and the frequency of primary cilia were detected, respectively.Results:Compared with control, the expression of miR-182-5p was significantly upregulated in PTC and TPC-1, the frequency of primary cilia in PTC and TPC-1 was downregulated. Overexpressing miR-182-5p increased the migrated number of TPC-1 cell and reduced the number of TPC-1 cell migration(27%, P=0.002); After siRNA-IFT88 treatment, primary cilia in TPC-1 became shorter and thinner, with a decrease in frequency( P=0.001), the migrated number of TPC-1 cell increased, and TPC-1 cell showed smaller nuclei and fewer microvilli. Conclusion:The regulation of primary cilia loss by miR-182-5p through the PI3K pathway contributes to the migration of TPC-1 cells. The loss of primary cilia has an adverse impact on the prognosis of PTC.

Climate change has led to an increasing frequency and intensity of extreme climate events such as heat and drought extremes with considerable global public health burden. This systematic review collected 87 domestic and international studies from 2000 to 2023, considering the impacts of heat extremes, drought extremes, and compound hot-dry events on infectious diseases attributable to various transmission pathways such as waterborne, foodborne, insect-borne, airborne, and contact-transmitted diseases. Our results showed that high temperature was associated with increased transmission risks of waterborne and foodborne diseases including infectious diarrheal diseases (cholera, dysentery, typhoid, and paratyphoid) and infectious gastroenteritis; vector-borne diseases including dengue fever, Zika virus (ZIKV) disease, chikungunya fever, malaria, West Nile fever, and Rift Valley fever; airborne diseases including influenza-like diseases, influenza A, measles, and mumps; and contact-transmitted diseases including HIV/AIDS, schistosomiasis, and leptospirosis. Additionally, drought conditions also amplified the transmission risks of waterborne and foodborne diseases including cholera, Escherichia coli infection, rotavirus infection, and hepatitis E; vector-borne diseases such as scrub typhus, schistosomiasis, hemorrhagic fever with renal syndrome, and West Nile fever; airborne diseases including meningococcal meningitis, pertussis, measles, and upper respiratory infections; and contact-transmitted diseases such as HIV/AIDS. Along with global warming, the frequency of compound high temperature and drought events shows a considerably increasing trend, causing more adverse health effects than heat or drought alone. However, there is limited research quantifying their effects on infectious diseases. These associations may be mediated through temperature and precipitation on infectious disease pathogens, transmission vectors, population susceptibility, public health services, and behaviors. In the context of climate change, the increasing occurrence of compound events of high temperatures and droughts raises health concerns, and further studies are needed to enhance our understanding of the impacts of climate change on infectious diseases and improve human adaption to climate change.
