ObjectiveBased on traditional quality evaluation of Gardeniae Fructus(GF) recorded in historical materia medica, this study systematically compared the quality differences between wild and cultivated GF from morphological characteristics, microscopic features, and contents of primary and secondary metabolites. MethodsVernier calipers and analytical balances were used to measure the length, diameter and individual fruit weight of wild and cultivated GF, and the aspect ratio was calculated. A colorimeter was used to determine the chromaticity value of wild and cultivated GF, and the paraffin sections of them were prepared by safranin-fast green staining and examined under an optical microscope to observe their microstructure. Subsequently, the contents of water-soluble and alcohol-soluble extracts of wild and cultivated GF were detected by hot immersion method under the general rule 2201 in volume Ⅳ of the 2020 edition of the Pharmacopoeia of the People's Republic of China, the starch content was measured by anthrone colorimetric method, the content of total polysaccharides was determined by phenol-sulfuric acid colorimetric method, the sucrose content was determined by high performance liquid chromatography coupled with evaporative light scattering detection(HPLC-ELSD), and the contents of representative components in them were measured by ultra-performance liquid chromatography(UPLC). Finally, correlation analysis was conducted between quality traits and phenotypic traits, combined with multivariate statistical analysis methods such as principal component analysis(PCA) and orthogonal partial least squares-discriminant analysis(OPLS-DA), key differential components between wild and cultivated GF were screened. ResultsIn terms of traits, the wild GF fruits were smaller, exhibiting reddish yellow or brownish red hues with significant variation between batches. While the cultivated GF fruits are larger, displaying deeper orange-red or brownish red. The diameter and individual fruit weight of cultivated GF were significantly greater than those of wild GF, while the blue-yellow value(b*) of wild GF was significantly higher than that of cultivated GF. In the microstructure, the mesocarp of wild GF contained numerous scattered calcium oxalate cluster crystals, while the endocarp contained stone cell class round, polygonal or tangential prolongation, undeveloped seeds were visible within the fruit. In contrast, the mesocarp of cultivated GF contained few calcium oxalate cluster crystals, or some batches exhibited extremely numerous cluster crystals. The stone cells in the endocarp were predominantly round-like, with the innermost layer arranged in a grid pattern. Seeds were basically mature, and only a few immature seeds existed in some batches. Regarding primary metabolite content, wild GF exhibited significantly higher total polysaccharide level than cultivated GF(P<0.01). In category-specific component content, wild GF exhibited significantly higher levels of total flavonoids and total polyphenols compared to cultivated GF(P<0.01). Analysis of 12 secondary metabolites revealed that wild GF exhibited significantly higher levels of Shanzhiside, deacetyl asperulosidic acid methyl ester, gardenoside and chlorogenic acid compared to cultivated GF(P<0.01). Conversely, the contents of genipin 1-gentiobioside, geniposide and genipin were significantly lower in wild GF(P<0.01). ConclusionThere are significant differences between wild and cultivated GF in terms of traits, microstructure, and contents of primary and secondary metabolites. At present, the quality evaluation system of cultivated GF remains incomplete, and this study provides a reference for guiding the production of high-quality GF medicinal materials.

Objective:To study the clinical value of color Doppler ultrasonography in the diagnosis of persistent sciatic vein(PSV).Methods:A retrospective study was performed on 17 patients who were diagnosed with PSV by color Doppler ultrasound in the Second Hospital of Shandong University and the Shandong Provincial Hospital Affiliated to Shandong First Medical University from May 2010 to December 2021. Their sonographic features were analyzed, summarized and classified.Results:In all the 17 cases, the sciatic vein showed a vein adjacent to the sciatic nerve in the pelvis or back of the thigh. According to anatomy, persistent sciatic vein could be divided into three types: complete PSV, upper PSV and lower PSV. There were 7 cases of complete PSV, 2 cases of upper PSV and 8 cases of lower PSV. Femoral vein dysplasia was found in 11 of 17 patients with PSV. In addition to 1 case of bilateral PSV, the diameter of the femoral vein on the affected side was (0.36±0.19)cm in 16 cases, and the diameter of femoral vein at the corresponding position on the healthy side was (0.61±0.11)cm, there was significant difference between the two groups ( P<0.001). Conclusions:Color Doppler ultrasonography is the effective imaging method for diagnosis of the PSV.

Objective:To investigate the effectiveness of abdominal compression in tumor motion and the target volume, and analyze the suitable margins of planning target volume (PTV) for patients treated with lung-SBRT based on 4DCT.Methods:Patients diagnosed with peripheral pulmonary tumor were enrolled. The patients were divided into the whole group, upper-middle-lobe group (group A) and the lower-lobe group (group B). Each patient underwent 3DCT, 4DCT with abdominal compression (4DCT com) and 4DCT with free breath (4DCT free) scans. The GTVs were delineated and IGTVs on these images. PTV MIP 5 mm, PTV MIP 4 mm, PTV MIP 3 mm were constructed with a 5, 4, 3 mm margin in left-right (LR), anterior-posterior (AP) directions and cranial-caudal (CC) directions. Results:The median motion vector with compression reduced by 30.92% in whole group, increased by 3.42% in group A and reduced by 18.80% in group B, respectively. And there were no significant differences of TMA LR, TMA AP, TMA CC and motion vector by the Wilcoxon test ( P>0.05). The median sizes of IGTV MIP com , IGTV MIP free and IGTV10 com, IGTV10 free were 4.01, 5.36 cm 3and 6.59, 7.65 cm 3, with statistically significant difference ( Z=-3.45, -3.14, P<0.01). The median ratio of DI of IGTV CBCT com in PTV MIP 5 mm, PTV MIP 4 mm and PTV MIP 3 mm≥95% was 100%, 100% and 83.33%, respectively. Conclusions:The patients′ respiratory pattern changed with abdominal compression and abdominal compression is useful in reducing the size of IGTV MIP and IGTV10, which could reduce the target volume and protect the normal tissue. Adding a 4 mm margin to IGTV MIP com based on 4DCT account for respiration in SBRT is a tendency for precise radiotherapy.
