ABSTRACT
Jiawei Xiaoyao San (JWXYS) has shown excellent clinical efficacy in anxiety disorder, but has not yet attracted widespread attention. The animal experiments, clinical trials and mechanism studies of JWXYS were reviewed in this article, which may provide a reference for developing new anxiolytic drugs based on this prescription. The literature was searched in PubMed and CNKI and the documents written in English or with English abstracts were selected. JWXYS could reduce the anxiety symptoms of patients alone and reduce the adverse reactions when it is used in combination with other drugs in the clinic. In preclinical studies, JWXYS also showed therapeutic effects in reducing anxiety-like behavior. The mechanisms may include improving the hypothalamic-pituitaryadrenal (HPA) axis and hormone disorders, increasing neurotransmitter content, neurogenesis, and regulating the synthesis of related enzymes. This article shows that JWXYS could effectively treat anxiety disorders by regulating the central nervous system. In the future, with the participation of more researchers, it is expected to develop innovative drugs for the treatment of anxiety disorders based on JWXYS.
ABSTRACT
Objective:To investigate the application and curative effect of fat grafting in supraorbital area in double blepharoplasty in patients with negative vector of the eyelid- globe.Methods:From January 2019 to January 2020, 78 patients who came to Fuzhou Meilai Huamei Beauty Hospital for double blepharoplasty were collected as patients with negative eyelid- globe vector. The patients were randomly divided into 2 groups, with 42 cases in the combined group and 36 cases in the simple group. The combined group underwent double blepharoplasty combined with fat grafting in the supraorbital area, and the simple group only underwent double blepharoplasty.Results:The postoperative follow-up was 3-12 months, with an average follow-up of 6 months. The efficacy of the combined group and the simple group was compared. There was no surgical complications in both groups. In improving the eyelid-globe vector, the combined group was higher than that of the simple group. The overall satisfaction of the combined group was higher than that of the simple group. Among them, the satisfaction of eye appearance, self-confidence, mental health, surgical results, decision-making and facial rejuvenation were all higher than those of the simple group, and there was no difference in the impact on early life between the two groups.Conclusions:Double blepharoplasty undergoing fat grafting in the supraorbital area at the same time are safe and conforms to the aesthetic standard. The patients are satisfied with the postoperative effects.
ABSTRACT
Objective:To explore the expression of long non-coding RNA-myeloid differentiation factor 88 (lnc-MyD88) and its relationship with the prognosis of patients with epithelial ovarian cancer (EOC).Methods:A total of 70 EOC patients who underwent initial cytoreductive surgery and platinum-based drugs combined with paclitaxel for 6 to 8 courses were selected at Sichuan Cancer Hospital from January 2016 to January 2019. The fresh cancer tissue specimens were collected. In addition, 28 fresh normal ovarian tissues from patients who underwent surgery for benign gynecological diseases during the same period were collected as control group. Reverse transcription (RT) and real-time quantitative polymerase chain reaction (qPCR) were used to detect the expression of lnc-MyD88 and myeloid differentiation factor 88 (MyD88) mRNA in EOC tissues and normal ovarian tissues. The correlation between the expression of lnc-MyD88 and MyD88 mRNA in EOC was analyzed by Pearson′s correlation coefficient. The relationship between lnc-MyD88 expression and clinicopathological characteristics of patients with EOC was analyzed. Kaplan-Meier method was used to calculate the survival rate of patients. The log-rank test was used for univariate survival analysis, and Cox proportional hazard model was used for multivariate survival analysis.Results:(1) RT-qPCR showed that the relative expression level of lnc-MyD88 and MyD88 mRNA in EOC were 0.009 (0.000-0.049) and 0.001 (0.000-0.006), respectively, which were significantly higher than those of normal ovarian tissues (all P<0.01); Pearson′s correlation coefficient showed that the expression of lnc-MyD88 and MyD88 mRNA in EOC was positively correlated ( r2=0.610, P<0.01). (2) The high expression rate of lnc-MyD88 in EOC patients with lymph node metastasis, distant metastasis and chemotherapy resistance (71%, 64% and 70%, respectively) were significantly higher than the patients in control group (41%, 40% and 35%, respectively; all P<0.05). There were no statistically significant in the high expression rate of lnc-MyD88 in EOC patients with different ages, pathological types, pathological grades, surgical pathological stages, postoperative residual lesion size, and ascites cancer cells (all P>0.05). (3) Univariate analysis showed that surgical pathological staging, lymph node metastasis, distant metastasis, postoperative residual tumor size, and high expression of lnc-MyD88 and MyD88 mRNA significantly affected the progression-free survival (PFS) and overall survival (OS) of EOC patients (all P<0.05), ascites cancer cells were the risk factors that significantly affected PFS in EOC patients ( P=0.040); multivariate analysis showed that surgical pathological staging and high expression of lnc-MyD88 and MyD88 mRNA were independent factors affecting PFS and OS in EOC patients (all P<0.05), the size of residual lesions after surgery was an independent factor affecting PFS in EOC patients ( P=0.001). Conclusions:The level of lnc-MyD88 expression in ovarian cancer tissues was significantly increased. Lnc-MyD88, as a molecular marker for the poor prognosis of EOC, is related to the expression of MyD88 in EOC, and may be involved in its expression regulation, thereby affecting the survival and prognosis of EOC patients.

ABSTRACT
Traditional Chinese medicine (TCM) property theory is believed to be a key and difficult point of basic theory studies of TCM. Complex concepts, components and characteristics of TCM property have long puzzled researchers and urged them to develop new angles and approaches. In the view of cognitive science, TCM property theory is a cognitive process of storing, extracting, rebuilding and summarizing the sensory information about TCMs and their effects during the medical practice struggling against diseases under the guidance of traditional Chinese philosophical thinking. The cognitive process of TCM property has particular cognitive elements and strategies. Taking into account clinical application characteristics of TCMs, this study defines the particular cognitive elements. In the combination of research methods of modern chemistry, biology and mathematics, and on the basis early-stage work for five years, we have built a TCM property cognition model based on three elements and practiced with drugs with pungent and hot properties as example, in the hope of interpreting TCM properties with modern science and providing thoughts for the nature of medical properties and instruction for rational clinical prescription.
