OBJECTIVETo observe the clinical effects and the serous estradiol change of patients with menopause syndrome using Xianling Gubao capsules for treatment.

METHOD110 patients with manopause syndrome who were diagnosized by clinic index were recruited for the study. They were divided into two groups randomly. The treatment group were dealed with Xianling Gubao capsules and the control group with placebo of starch capsules for 8 weeks. The menopausal Kupperman index was used to assess change in menopausal symptoms before and after treatment. At the same time, serous estradiol and the thickness of uterine endometrium was evaluated.

RESULTThe Kupperman index were improved apparently in treatment group after treatment (P < 0.01). The serous estradiol level of treatment group was increased apparently after treatment (P < 0.05). However, There were no statistical deference in the thickness of uterine endometrium in the treatment and the control group before and after treatment.

CONCLUSIONThe treatment using Xianling Gubao capsules for patients with menopause syndrome could improve the clinic symptoms, increase the serous estradiol level, but do not increase the risk of endometrial hyperplasia.

Objective To observe the effects of wheat grain moxibustion for"Huantiao"on sciatic nerve function,pathological morphology of sciatic nerve stem and expressions of TLR4/MyD88/NF-κB signaling pathway expression in spinal cord tissue of rats with sciatic nerve injury(SNI);To explore the possible mechanism of wheat grain moxibustion for the treatment of SNI.Methods Totally 24 SD male rats were randomly divided into blank group,sham-operation group,model group and wheat grain moxibustion group,with 6 rats in each group.The model group and the wheat grain moxibustion group used a rat model with sciatic nerve clamping injury.From the 7th day after modeling,the rats were treated with moxibustion on the affected side of"Huantiao"for 6 strokes each time,once a day,for consecutive 10 days.The sciatic nerve function index(SFI)of rats on the 7th day after modeling and after intervention were observed,mechanical withdraw threshold(MWT)in rats were measured using a fiber optic pain gauge,ELISA was used to detect NO and iNOS content in spinal cord tissue,HE staining was used to observe the morphology of sciatic nerve stem,the expression of TLR4,NF-κBp65,p-NF-κBp65,MyD88,IκBα and p-IκBα in spinal cord tissue were detected by Western blot.Results Compared with the sham-operation group,the SFI and MWT of the rats in the model group significantly decreased(P<0.01),the arrangement of nerve fibers in sciatic nerve stem was disordered,with a significant increase in the number of Schwann cells and a large number of vacuolar degeneration,the content of NO,iNOS and the expression of TLR4,p-NF-κBp65,MyD88,p-IκBα protein in spinal cord tissue significantly increased(P<0.01).Compared with the model group,the SFI and MWT of the rats in the wheat grain moxibustion group increased significantly(P<0.01),the damage of sciatic nerve stem was reduced,with orderly cell arrangement,a decrease in the number of Schwann cells,and a decrease in axonal demyelination and cellular vacuolar degeneration,the content of NO,iNOS and the expression of TLR4,p-NF-κBp65,MyD88,p-IκBα in spinal cord tissue significantly decreased(P<0.05).Conclusion Wheat grain moxibustion for"Huantiao"can down-regulate TLR4,p-NF-κBp65,MyD88 and p-IκBα protein expressions in spinal cord tissue of SNI rats,reduce the secretion of NO and iNOS,thereby relieve pain and damaged nerve tissue inflammation response.

Objective:To investigate changes in skin microecological structures and functions between acute and remission phases in adult patients with severe atopic dermatitis (AD) .Methods:From October 2019 to November 2020, skin scale specimens were collected from 5 body sites (cheeks, cubital fossa, back of the hand, abdomen, lower limbs) of 4 adult patients with severe AD in the acute and remission phases, who visited the outpatient clinic of Guangzhou Institute of Dermatology. The next-generation high-throughput sequencing was performed for metagenomic sequencing to construct the microbial gene catalogue of these specimens, followed by gene annotation and bioinformatics analysis for each sample.Results:A total of 18 phyla, 37 classes, 73 orders, 142 families, 237 genera, and 331 species were identified in the skin specimens from the 4 patients with severe AD. The patients with AD in the remission phase showed significantly increased diversity of skin microbiota and markedly different relative abundance of skin microorganisms compared with those in the acute phase (both P < 0.05). At the microbial species level, Staphylococcus aureus showed the highest impact on the acute phase of AD, while Staphylococcus epidermidis, Moraxella osloensis, Francisella sp., Staphylococcus cohnii, Staphylococcus warneri, Malassezia globosa and Malassezia restricta were enriched in the remission phase of AD with the absolute value of the common logarithm of the linear discriminant analysis score > 2 (Kruksal-Wallis test, all P < 0.05). As KEGG pathway enrichment analysis showed, the differentially abundant genes were annotated into a total of 355 functional pathways, of which 38 pathways were significantly enriched (all P < 0.05), mainly involving Staphylococcus aureus infection, tryptophan metabolism, histidine metabolism, nitrogen metabolism, metabolism of arginine and proline, biosynthesis and degradation of valine, leucine and isoleucine, fatty acid degradation, peroxisome proliferator-activated receptor signaling pathway, etc. Conclusion:The skin microecological structure significantly differed between the acute and remission phases among the patients with severe AD, which may be related to multiple functional pathways, such as Staphylococcus aureus infection, tryptophan metabolism, histidine metabolism and nitrogen metabolism.

To establish mouse endometrial injury model by curettage or coagulation.Female ICR mice were randomly allocated into 2 groups: in curettage group, a blunt 20G needle was inserted in one uterine horn with 0.05 megapascals negative pressure; in coagulation group, one uterine horn was coagulated using a monopolar electric needle with 0.5 watts power. In both groups the contra-lateral uterine horn was used as control. The morphological changes and thickness of endometrium were evaluated 1 week after operation. The endometrial samples were taken on d4 of pregnancy, and the expressions of endometrial receptivity-related cytokines were examined. The number of implanted embryos on each side of uterus was calculated on d10 of pregnancy.There was no difference in operation time between 2 groups. In both groups, the endometrial glands and stroma were significantly reduced, and the endometrial thickness was also significantly decreased on injury side compared to contra-lateral horn. However, local injury was more severe in coagulation group, uterine obliteration and hydrops were developed in 2 mice of coagulation group, and none in curettage group. The expressions of leukemia inhibitory factor (LIF) and oncostatin M (OSM) were significantly reduced on injured side in both groups compared to opposite side; however, the expression of LIF and OSM in curettage group was higher than that in coagulation group. The numbers of implanted embryos were decreased in both groups on injured side compared to opposite side, and fetal death was only observed in coagulation group.Both curettage and coagulation can make injury on mouse endometrium, impair endometrial receptivity and reduce fertility. Curettage can cause moderate injury, and coagulation may lead to more severe injury.
