This study aimed to characterize and identify the non-volatile components in aqueous and ethanolic extracts of the stems and leaves of Rhododendron tomentosum by using sensitive and efficient ultra-performance liquid chromatography-quadrupole-time of flight mass spectrometry(UHPLC-Q-TOF-MS) combined with a self-built information database. By comparing with reference compounds, analyzing fragment ion information, searching relevant literature, and using a self-built information database, 118 compounds were identified from the aqueous and ethanolic extracts of R. tomentosum, including 35 flavonoid glycosides, 15 phenolic glycosides, 12 flavonoids, 7 phenolic acids, 7 phenylethanol glycosides, 6 tannins, 6 phospholipids, 5 coumarins, 5 monoterpene glycosides, 6 triterpenes, 3 fatty acids, and 11 other types of compounds. Among them, 102 compounds were reported in R. tomentosum for the first time, and 36 compounds were identified by comparing them with reference compounds. The chemical components in the ethanolic and aqueous extracts of R. tomentosum leaves and stems showed slight differences, with 84 common chemical components accounting for 71.2% of the total 118 compounds. This study systematically characterized and identified the non-volatile chemical components in the ethanolic and aqueous extracts of R. tomentosum for the first time. The findings provide a reference for active ingredient research, quality control, and product development of R. tomentosum.

OBJECTIVE:
The present study evaluated the effects of deep acupuncture at Weizhong acupoint (BL40) on bladder function and brain activity in a rat model of overactive bladder (OAB), and investigated the possible mechanisms around the acupuncture area that initiate the effects of acupuncture.
METHODS:
Adult female Sprague-Dawley rats were randomly divided into six groups, comprising a control group, model group, group treated with deep acupuncture at BL40, group treated with shallow acupuncture at BL40, group treated with acupuncture at non-acupoint next to BL40, and group treated with acupuncture at Xuanzhong (GB39). Urodynamic evaluation was used to observe the urination, and functional magnetic resonance imaging was used to observe the brain activation. The mechanism of acupuncture at BL40 in regulating bladder function was explored by toluidine blue staining and enzyme-linked immunosorbent assay, and the mechanism was verified by stabilizing mast cells (MCs) or blocking tibial nerve.
RESULTS:
Deep acupuncture at BL40 significantly increased the intercontraction interval in OAB rats and enhanced the mean amplitude of low frequency fluctuation of primary motor cortex (M1), periaquaductal gray matter (PAG), and pontine micturition center (PMC). It also increased the zero-lag functional connectivity between M1 and PAG and between PAG and PMC. Shallow acupuncture at BL40 and acupuncture at non-acupoint or GB39 had no effect on these indexes. Further studies suggested that deep acupuncture at BL40 increased the number and degranulation rate of MCs as well as the contents of 5-hydroxytryptamine, substance P, and histamine in the tissues around BL40. Blocking the tibial nerve by lidocaine injection or inhibiting MC degranulation by sodium cromoglycate injection obstructed the effects of acupuncture on restoring urinary function and modulating brain activation in OAB rats.
CONCLUSION
Deep acupuncture at BL40 may be more effective for inhibiting OAB by promoting degranulation of MCs around the acupoint and stimulating tibial nerve, thereby regulating the activation of the brain area that controls the lower urinary tract.

ObjectiveTo explore the influence of electroacupuncture combined with point bloodletting and cupping for facial nerve function recovery in acute stage of idiopathic facial palsy (IFP). MethodsEighty patients with IFP in the acute stage were randomly divided into 40 cases each in the treatment group and the control group. In the control group, oral prednisone acetate tablets were administered during the acute stage when the disease duration was less than 10 days; and electroacupuncture and flash cupping were provided during the recovery stage when the disease duration was more than 10 days, five times a week. For treatment group in acute stage, the stellate ganglion, vagus nerve stimulation point in the auricular cavity, Yifeng (TE 17) and Tinghui (GB 2) were needled on the affected side on the basis of the treatment of control group, with Yifeng and Tinghui connecting to electroacupuncture apparatus, once a day; point bloodletting and then cupping in Yifeng 2 times a week; in recovery stage, the treatment was the same as that of the control group. Both groups were treated until the 45th day from onset. The primary outcome was the Toronto facial grading system (SFGS), and the secondary outcomes included house-brackmann (H-B) grade, facial disability index (FDI) score, and number of H-B grade-Ⅰ cases. Adverse events were recorded in both groups. ResultsThe SFGS scores of the patients in both groups were higher on the 10th, 30th and 45th days after onset of disease compared with those before the treatment (P<0.05); the H-B grade was lower on the 30th and 45th days after the onset of the disease compared with those before the treatment (P<0.05); and the facial disability index physical function (FDIP) and facial disability index social function (FDIS) scores were higher on the 30th and 45th days after onset of disease (P<0.05). SFGS scores of patients in the treatment group were significantly higher than those of the control group on the 30th and 45th days after onset (P<0.05); H-B grade was significantly lower than that of the control group on the 30th and 45th days after onset (P<0.05); and FDIP scores on the 45th day after onset, and FDIS scores on the 30th and 45th days after onset were significantly higher than those of the control group (P<0.05). At the end of treatment, 77.50% (31 cases) achieved H-B grade-Ⅰ in the treatment group, which was more than 55.00% (22 cases) in the control group (P<0.05). No adverse events occurred in either group. ConclusionElectroacupuncture combined with point bloodletting and cupping for IFP in acute stage can improve the recovery degree of facial nerve function, improve effectiveness, and show a high degree of safety.

[Objective] To analyze the correlation of the distribution and morphological characteristics of breast calcification with the risk of breast malignant tumors, so as to further reveal the important value of the calcification in diagnosis of breast malignant tumors. [Methods] A total of 108 patients who had received concurrent puncture biopsy and surgical treatment of breast calcification at The Second Affiliated Hospital of Xi’an Jiaotong University from January 1, 2019 to December 31, 2019 were recruited, and their imaging data and postoperative pathological results were analyzed. We divided the distribution of breast X calcification into two categories based on segmental/linear calcification and regional/diffuse calcification. We classified the morphology of breast X calcification into punctate, small branching, polymorphic, amorphous, and coarse ones. We then explored the distribution, morphology, and BI-RADS classification of tumor calcification under breast X-ray, and its correlation with the occurrence, age, menopausal status, hormone receptors, and molecular typing of breast malignant tumors. [Results] Among the 108 patients enrolled in the study, 21 cases were malignant and 87 cases were benign. The results showed that the distribution of calcification was segmental/linear (χ2=11.2, P=0.003) and the calcification morphology was of small branching calcification (χ2=9.3, P=0.046). The detection rate in malignant tumors was significantly higher than that in benign tumors. The distribution and morphology of calcification were not significantly correlated with ER, PR, HER2, Ki67, pathological type, or molecular typing (P>0.05). Logistic regression analysis showed that , calcification distribution was segmental/linear [OR=19.94(3.061-129.9), P=0.002], calcification morphology was small branching [OR=3.906(1.141-13.37), P=0.030], and B-RADS classification was 4 grade and above [OR=39.99(2.703-591.7), P=0.007], which were closely related to the occurrence of malignant tumors. [Conclusion] For patients with breast tumors in which calcification can be detected under mammography, their imaging characteristics are closely related to the occurrence of malignant tumors. The distribution of calcification is segmental/linear, and the morphology of calcification is small branching/amorphous, which is more likely to be a malignant tumor and closely related to the occurrence of breast cancer.
