OBJECTIVE
To explore the mechanism of steam-processed Polygonatum sibiricum polysaccharides(SPSP) in prophylaxis and treatment of mice with blood deficiency syndrome(BDS) by RNA sequencing(RNA-seq) technology.
METHODS
The mice were randomly divided into five groups(10 mice in each group), namely normal group, model group, SPSP groups(0.1, 0.4 g·kg−1), Danggui Buxue oral liquid(DOL) group. BDS model was induced in mice by acetylphenyl-hydrazine and cyclophosphamide. Blood routine, body weight and body temperature were tested after a consecutive administration for 14 d. The differential expressed genes(DEGs) related to anti-BDS by SPSP were screened through the transcriptome sequencing of the hepatic tissue in BDS mice. Functional annotation and enrichment analysis were performed to screen out the gene expression signaling pathways related to the treatment of SPSP on BDS mice. Quantitative polymerase chain reaction(qPCR) was used to verify the experiment.
RESULTS
Compared with the model group, SPSP(0.4 g·kg−1) could elevate the blood routine indexes such as red blood cell, white blood cell, hemoglobin, platelet, mean corpuscular hemoglobin concen-tration(P<0.01), and reverse the body weight and body temperature to normal(P<0.01 or P<0.05). The result of transcriptomic analysis showed that the underlying mechanism was mainly related to hematopoietic cell line, retinol metabolism, steroid hormone biosynthesis, platelet activation, B cell receptor signaling pathway, and leukocyte transendothelial migration, etc. The result of qPCR showed that SPSP(0.4 g·kg−1) could elevate the expression of JAK1, STAT1 and GATA1 mRNA (P<0.01 or P<0.05).
CONCLUSION
SPSP has therapeutic effects on BDS. The key DEGs in the treatment of BDS by SPSP are mainly related to the restoration of hematopoietic function, regulation of hormone and immune function. The mechanism of SPSP on treatment of BDS might be the regulation of JAK1/STAT1 signaling pathway.

ObjectiveTo explore the distribution characteristics of traditional Chinese medicine (TCM) syndrome elements of macroangiopathy in patients with type 2 diabetes mellitus (T2DM) and the key elements of occurrence, development and progression of disease. MethodsA multicenter cross-sectional study was conducted to enroll 445 T2DM patients from five hospitals, and according to the presence or absence of macroangiopathy, the patients were divided into a T2DM group (120 cases) and a diabetic macroangiopathy (DM) group (325 cases). Patients in DM group were divided into grade Ⅰ, Ⅱ, Ⅲ and Ⅳ according to the peripheral vascular color Doppler ultrasound results and the vascular anomalies classification standard. The general data including gender, age, duration of T2DM and body mass index (BMI) were collected, and the data of four examinations were obtained for syndrome differentiation. According to the diagnostic criteria of TCM syndrome elements, the patients can be divided into 9 patterns including qi deficiency, blood deficiency, yin deficiency, yang deficiency, qi stagnation, blood stasis, excess heat, and excess cold. The general data and distribution of TCM syndrome elements were compared between the two groups. The distribution of TCM syndrome elements in different vascular anomalies grades in the DM group was analyzed. Logistic regression analysis was used to explore the influence of various TCM syndrome elements on the occurrence of macroangiopathy in T2DM. ResultsThere was no significant difference in gender and BMI between groups (P>0.05). The age and duration of diabetes in the DM group were older and longer than those in the T2DM group (P<0.01). With the increase of age and prolonged course of disease, the severity of diabetic macroangiopathy increases gradually (P<0.05 or P<0.01). There was no significant difference in BMI and course of disease among the different TCM syndrome elements (P>0.05). The average age of patients with blood stasis syndrome was the oldest (P<0.05). There was significant difference in gender distribution between the excess heat syndrome and yin deficiency syndrome (P<0.05). A total of 240 TCM syndrome elements were extracted from the T2DM group, while 731 TCM syndrome elements extracted from the DM group. The top two high-frequency syndrome elements in the two groups were qi deficiency and yin deficiency, with a frequency of larger than 50%. The distribution of phlegm-damp syndrome and blood-stasis syndrome were significantly higher in the DM group than in the T2DM group (P<0.01). There were significant differences in the distribution of qi deficiency syndrome, yin deficiency syndrome, phlegm-damp syndrome, blood stasis syndrome, and excess heat syndrome among different grades of vascular anomalies (P<0.01); qi deficiency and yin deficiency were both high-frequency TCM syndrome elements in patients at grades 0 to Ⅲ; phlegm-damp syndrome increased in frequency with the progression of the disease from grades 0 to Ⅳ, and the frequency of blood stasis syndrome showed an overall upward trend. The frequency of phlegm-dampness syndrome increased from grades 0 to Ⅳ with the progression of the disease, and the frequency of blood stasis syndrome showed an overall upward trend. Logistic regression analysis showed that phlegm-damp syndrome and blood stasis syndrome were important TCM syndrome elements related to the vascular anomalies degree of macrovascular disease in T2DM (P<0.05 or P<0.01). ConclusionQi deficiency and yin deficiency are the basic TCM syndrome elements throughout the whole process of T2DM and diabetic macrovascular disease. Phlegm-damp and blood stasis are related to the degree of vascular anomalies in diabetic macrovascular disease and are the key TCM syndrome elements in the progression of macroangiopathy in T2DM.

Objective:To investigate the relationship between the clinical efficacy and the ablated area of endometrium in patients with internal adenomyosis treated with focused ultrasound ablation surgery (FUAS).Methods:From January 2015 to December 2018, 122 patients in Chongqing Haifu Hospital who were diagnosed as internal adenomyosis through history, clinical symptoms and enhanced magnetic resonance imaging (MRI) and treated with FUAS were enrolled in this study. According to the patient′s wishes, patients were given whether to ablate the adenomyotic lesion alone or ablate the adenomyotic lesion and the endometrium that involved in adenomyotic lesions together. The ablated area of adenomyotic lesions and endomitrium were evaluated by post-FUAS enhanced MRI. The adverse events and the changes of dysmenorrhea and menstrual volume at different follow-up points within 24 months were recorded.Results:Among the 122 patients, 32 patients chose to ablate adenomyotic lesion alone, and 90 patients chose to ablate the adenomyotic lesion and the endometrium during FUAS. No major complications such as bowel injury and nerve injury occurred after FUAS. The median non-perfused volume ratio of adenomyotic lesions was 31.7% in the group without endometrial ablation and it was 60.0% in the group with endometrium ablation ( P<0.01). The improvement of dysmenorrhea in the group with endometrium ablation was significantly better than the group without endometrial ablation ( P<0.01). The average menstrual volume score (3.4±0.9) before FUAS in the group with endometrial ablation was higher than that in the group without endometrial ablation (2.5±0.6; P<0.01), but it decreased significantly after FUAS treatment, reaching the similar menstrual volume score of the group without endometrial ablation ( P>0.05). The proportions of abnormal vaginal discharge (34.4%, 31/90) and bleeding (16.7%, 15/90) were significantly higher in the group with endometrium ablation than those in the group without endometrial ablation (all P<0.01). Conclusions:FUAS could be safely and effectively used in the treatment of patients with internal adenomyosis. It seems that ablation of adenomyotic lesion and endometrium together could obtain better therapeutic effects.

OBJECTIVE:
To assess the application value of mapping allele with resolved carrier status (MaReCs) technique for preimplantation genetic testing (PGT).
METHODS:
The characteristics of MaReCs for PGT and outcome of patients were retrospectively analyzed.
RESULTS:
Compared with those who could not use the technique, carriers who have used the MaReCs technique were younger, had significantly higher level of anti-Mullerian hormone, more antral follicles, occytes, mature occytes, biopsied embryos and euploid embryos, and lower risks for de novo chromosomal abnormality (P<0.05). It was necessary for couples with fewer oocytes, mature oocytes and balstocyst to preserve discarded embryos to facilitate the test. Carriers who have used the MaReCs technique had higher clinical pregnancy rate and abortion rate compared with those undergoing routine PGT, albeit no significant difference was found between the two groups (P> 0.05). Carriers undergoing MaReCs test could preferentially select embryos with normal chromosome structures for the transfer.
CONCLUSION
Application of MaReCs has a prerequisite for having a minimum number of occytes and biopsied embryos and using discarded embryos sometimes. MaReCs is efficient for the detection of carrier status of embryos and attaining higher rate of pregnancy and live birth, which can significantly improve the outcome for couples carrying chromosomal translocations.

Objective:To determine the expression of interleukin(IL)-23 and its influence on the associated cytokines and genes in different immune phases of chronic hepatitis B (CHB) patients.Methods:Our study included 197 patients with chronic hepatitis B(including 16 for immune tolerance phase, 106 for immune clearance phase, 59 for immune control phase and 16 for reactivation phase). The level of IL-23、IL-17、TGF-β、IL-10、IL-21 in plasma was detected by enzyme-linked immunosorbent assay (ELISA). The mRNA expression level of ROR-γt、Foxp3 was detected by real time quantitative PCR (RT-qPCR). The data were analyzed with IBM SPSS Statistics 23.0 software.Results:The level of IL-23、IL-17、IL-21、ROR-γt mRNA in CHB patients is significantly higher than normal controls ( P<0.05). The level of IL-23 is positively correlated with ALT、AST、GGT、TBil、IL-17、IL-21 in plasma and ROR-γt mRNA、Foxp3 mRNA level in PBMCs( P<0.05). The expression of IL-23、IL-17 and ROR-γt mRNA are different between different immune phases( P<0.05). Conclusions:IL-23 might play an important role on the different immune phases in chronic HBV infection through influencing associated cytokines and genes.
