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.

Objective To investigate the effect of hyperglycemia activated CCAAT enhancer binding protein β(C/EBPβ)promoting the expression of thyroid hormone nuclear receptor α1(THα1)on diabetic cardiomyopathy(DCM).Methods Twenty healthy male Wistar rats were randomly divided into diabetes mellitus(DM,n=10)group and DCM(n=10)group.Cardiomyocyte were divided into four groups:DM-cell,glucose intervention(Glu),knockdown C/EBPβ group(cardiomyocyte were transfected with plasmids targeting knockdown C/EBPβ)and si-NC group(cardiomyocyte were transfected with nagetive control sequence of plasmids).HE and Masson staining was performed to detect myocardial injury and collagen deposition.Echocardiography was used to evaluate left ventricular function.The mRNA and protein expression of C/EBP β and THα1 was detected using RT-qPCR,Western blot and immunofluorescence staining in myocardial cells.Apoptosis was analyzed using flow cytometric.Contraction frequency was counted by microscopy.Results Compared to DM group,count of fibroblasts,collagen volume fraction,end-systolic dimension of left ventricular,and the mRNA and protein expression of C/EBPβ and THα1 as well as fluorescence intensity increased(P<0.05);left ventricular ejection fraction and left ventricular fractional shortening(LVFS)decreased in DCM group(P<0.05).The mRNA and protein expression of C/EBPβ and THα1 were higher in the Glu group than in DM-cell group(P<0.05).The percentage of apoptosis,the mRNA and protein expression of THα1 of myocardial cells were lower in the si-C/EBPβ group than in the si-NC group(P<0.05),and LVFS was higher in the si-NC group(P<0.05).Conclusions High glucose regulates C/EBPβ expression,which in turn drives THα1 expression in myocardial tissue,leading to adverse effects on myocardial tissue.Conversely,silencing C/EBPβ downregulates THα1 expression,and exerts a protective effect on cardiomyocytes.

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.

AIM:To investigate the effects of microRNA-200a(miR-200a)on the formation of primary cilia and the apoptosis in X-ray-injured cardiac fibroblasts.METHODS:Hearts were isolated from neonatal Wistar rats and di-gested with trypsin.Cardiac fibroblasts were isolated,irradiated with 1 Gy of X-ray,and subsequently transfected with miR-200a-3p mimic or si-IFT88.Primary cilia were detected by immunofluorescence staining,and tranfoming growth fac-tor-β1(TGF-β1)in the culture medium was detected by ELISA.The viability of cardiac fibroblasts was detected by CCK-8.The mRNA expression of tumor necrosis factor-α(TNF-α)and caspase-3 was detected by RT-qPCR,and the protein expression of TNF-α,caspase-3,collagen type I α1 chain(Col1α1)and TGF-β1 was detected by Western blot.RE-SULTS:Compared with control group,X-ray irradiation significantly decreased the expression of miR-200a-3p and the level of apoptosis,but increased the proportion of cells with primary cilia,the length of primary cilia and the viability of cardiac fibroblasts.Compared with X-ray group,the percentage of apoptotic cardiac fibroblasts in si-IFT88 group was in-creased.Compared with X-ray group,the proportion of cells with primary cilia and the TGF-β1 content in cardiac fibro-blasts were reduced,and the proportion of apoptotic cells increased in miR-200a-3p overexpression group.CONCLU-SION:X-ray-induced down-regulation of miR-200a-3p in neonatal rat cardiac fibroblasts drives the formation of primary cilia and suppresses the apoptosis.

Objective:To investigate the effects of repeated high acceleration(+Gz)on implant osseointegration in SD rats.Methods:18 SD rats were divided into+Gz and control groups randomly(n=9),and 1 implant was placed in each femur of the rat's lower limb.24 hours postoperatively,the experimental rats were exposed to+Gz of 4 to 9 G with 1 G/s environment 3 times a week,while the con-trol rats were fed normally.3 rats from each of the 2 groups were sacrificed at 2,4 and 8 weeks after implantation.Micro-CT,sequential fluorescence double labeling,and histological examination were perfomed for the analysis of implant osseointegration.Results:The bone volume fraction(BV/TV),trabecular number(Tb.N),mineral apposition rate(MAR),implant-bone contact rate(BIC)and bone area in implant thread(BA)of the+Gz group were significantly lower than those of the control group at 2 weeks(P＜0.05),and so as to MAR,BA at 4 weeks(P＜0.05),while there was no significant difference of the parameters at 8 weeks after implantation.Conclusion:In SD rats early exposure to+Gz environment postoperatively may have a negative effect on initial osseointegration by slowing bone forma-tion.However,it will not lead to poorer bone mass when sustained over a long period.

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.
