Objective To investigate the effect of Simoyinzi Decoction on serum 5-HT and inflammatory factors in the treatment of perimenopausal women with early onset of severe depression.Methods 82 cases of perimenopausal women with primary severe depression were selected and randomly divided into 2 groups, 41 cases of each group.Control group received basic medicine treatment, the research group received Simoyinzi Decoction treatment,serum neurotransmitter, inflammatory factor and sex hormone levels were detected before and after the treatment, and clinical symptom score and clinical curative effect were compared after the treatment.Results Compared with before treatment, levels of noradrenaline norepinephrine(NE), 5 serotonin(5-HT), dopamine(DA), glutamate(Glu) and N-methyl-D-aspartate(Asp) increased in 2 groups after treatment, levels of gamma amino acid (GABA) and glycine(Gly) decreased, levels of follicle stimulating hormone(FSH) and luteinizing hormone(LH) decreased, levels of estradiol(E2) increased, levels of IL-1β, IL-6, TNF-αand CRP decreased, scores of HAMD and Kupperman decreased, the differences were statistically significant (P<0.05), compared with the control group, levels of NE, 5-HT, Glu and Asp in the research group after treatment were higher, levels of GABA and Gly were lower, levels of FSH and LH were lower, levels of E2 were higher, levels of IL-1β, IL-6, TNF-αand CRP were lower, and scores of HAMD and Kupperman were lower, the differences were statistically significant(P<0.05), and the effective rate in the control group(70.73%) was lower than the research group ( 90.24%) ( P <0.05 ) .Conclusion Simoyinzi Decoction in the treatment of perimenopausal women with early onset of severe depression was curative effective, and it can improve the 5-HT and reduce the levels of inflammatory factors.

Objective To investigate the antimicrobial susceptibility of spectinomycin?minocycline?azithromycin and sparfloxacin to mycoplasma(Uu and Mh)and therapeutic effect of spectinomycin to my-coplasma infection in genitourinary tract.Methods①The susceptibility test:each of the4drugs was divided into two concentrations.One was at1?g/mL(sensitive concentration)and the other was at4?g/mL(resistant concentration).If mycoplasma does not grow in both concentrations,it means the drug tested is sensitive.If it grows in both concentrations,the drug tested is resistant.If mycoplasma grows in lower concentration and does not in higher concentration,it means moderate sensitive.②Treatment regimen:Spectinomycin was injected,2g/d IM,for7-10days as a course of treatmeant.Patients were followed-up7days later and2~4weeks after treatment.Results①Among1658specimens,519were found Uu positive,and61Mh positive.The resis-tance rates of Uu to4different drugs were:7.7%for minocycline,21.4%for sparfloxacin,13.9%for azithromycin and7.3%for spectinomycin.Whereas,those of Mh were:18.0%,45.9%,54.1%,and29.5%re-spectively.②The clinical effect of spectinomycin was:out of43treated patients,37(86.0%)cured,4(9.3%)markedly improved,2(4.7%)failed.Total effective rate was95.3%and so was the elimination rate of my-coplasma.Conclusion The resistant rate of mycoplasma to spectinomycin is lower than that to minocycline?azithromycin and sparfloxacin,and the former is widely used in the treatment of mycoplasma(especially Uu)infection,with a satisfactory clinical effect.

Objective:To investigate drug resistance gene in Mycoplasma pneumoniae(MP) and the distribution of 13 respiratory pathogens in bronchoalveolar lavage fluid(BALF) of children with Mycoplasma pneumoniae pneumonia(MPP).Methods:A total of 100 BALF of children with MPP in Peking University Third Hospital and Peking University First Hospital from January 2018 to January 2019 were collected.Fluorogenic quantitative PCR was used to detect nucleic acid and it′s drug resistance gene of MP and multiple PCR method was adopted to detect influenza A virus, influenza A virus-H 1N 1, influenza A virus-H 3N 2, influenza B, human parainfluenza virus, adenovirus, human bocavirus, human rhinovirus, Chlamydia pneumoniae, human metapneumovirus, MP, human coronavirus, and respi-ratory syncytial virus gene, and the results were compared by using Chi square test. Results:In 100 BALF samples, MP and drug resistance gene were detected by fluorogenic quantitative PCR.Totally, 83 cases (83.00%) were MP positive and 78 cases (93.98%) were drug resistant.All of them had the point mutations A2063G in V region of 23S rRNA domain.A total of 13 kinds of respiratory pathogens were detected by multiplex PCR method, and 89 cases (89.00%) were positive.Totally, 79 cases (79.00%) were MP positive, of which 74 cases (74.00%) detected only MP, and 5 cases (5.00%) detected MP combined with other pathogens.Other pathogens were detected in 10 cases (10.00%). The virus detection rate of 0-4 years old group was higher than that of >4-6 years old group ( P=0.042) and >6 years old group ( P=0.002), and the differences were statistically significant. Conclusions:MP can be detected in most BALF samples of MPP children, the drug resistance phenomenon is serious, and the main point mutation is A2063G.There were other respiratory pathogens and 2 or 3 pathogens were detected in a small number of BALF samples.

OBJECTIVE: To summarize the research progress on the role of macrophage-mediated osteoimmune in osteonecrosis of the femoral head (ONFH) and its mechanisms. METHODS: Recent studies on the role and mechanism of macrophage-mediated osteoimmune in ONFH at home and abroad were extensively reviewed. The classification and function of macrophages were summarized, the osteoimmune regulation of macrophages on chronic inflammation in ONFH was summarized, and the pathophysiological mechanism of osteonecrosis was expounded from the perspective of osteoimmune, which provided new ideas for the treatment of ONFH. RESULTS: Macrophages are important immune cells involved in inflammatory response, which can differentiate into classically activated type (M1) and alternatively activated type (M2), and play specific functions to participate in and regulate the physiological and pathological processes of the body. Studies have shown that bone immune imbalance mediated by macrophages can cause local chronic inflammation and lead to the occurrence and development of ONFH. Therefore, regulating macrophage polarization is a potential ONFH treatment strategy. In chronic inflammatory microenvironment, inhibiting macrophage polarization to M1 can promote local inflammatory dissipation and effectively delay the progression of ONFH; regulating macrophage polarization to M2 can build a local osteoimmune microenvironment conducive to bone repair, which is helpful to necrotic tissue regeneration and repair to a certain extent. CONCLUSION At present, it has been confirmed that macrophage-mediated chronic inflammatory immune microenvironment is an important mechanism for the occurrence and development of ONFH. It is necessary to study the subtypes of immune cells in ONFH, the interaction between immune cells and macrophages, and the interaction between various immune cells and macrophages, which is beneficial to the development of potential therapeutic methods for ONFH.
