Objective:To clarify the M protein ( emm gene) types and drug susceptibility characteristic variations of Group A Streptococcus (GAS) in children in Beijing. Methods:The GAS strains isolated from throat swab samples of children diagnosed with scarlet fever and pharyngeal infection in scarlet fever etiology surveillance sentinel hospitals in 16 districts of Beijing in 2018, 2019 and 2021 were analyzed retrospectively.PCR amplification and sequencing were used for emm genotyping, and the minimum inhibitory concentrations (MIC) of 10 antibiotics were determined by the broth microdilution method.The data were analyzed using χ2 test and Fisher′ s exact method between groups. Results:A total of 557 GAS strains were collected, and 11 emm genotypes ( emm1, emm3, emm4, emm6, emm11, emm12, emm22, emm75, emm89, emm128, and emm212) were detected.Of 557 strains, 238 trains were of emm1 type (42.73%), 271 strains were of emm12 type (48.65%) and 48 strains were of other emm types (8.62%). The detection rates of emm1, emm12 and other emm type genes in 2018, 2019, and 2021 were [37.50% (105/280 strains), 57.14% (160/280 strains), 5.36% (15/280 strains)], [49.05% (129/263 strains), 39.54% (104/263 strains), 11.41% (30/263 strains)], and [28.57% (4/14 strains), 50.00% (7/14 strains), 21.43% (3/14 strains)], respectively.In children infected with emm12 in 2018 and 2019, there were more children under 6 years old than children over 6 years old (62.50% vs.46.88%, 46.36% vs.30.36%) (χ 2=7.182, 6.973; all P<0.05). Drug susceptibility testing results suggested that 225 randomly selected GAS strains were all 100.00% sensitive to 7 antibiotics including Penicillin, Levofloxacin, Meropenem, Linezolid, Cefotaxime, Cefepime and Vancomycin.The rates of resistance to Erythromycin, Tetracycline and Clindamycin were [88.57% (93/105 strains), 87.62% (92/105 strains), 86.67% (91/105 strains)], and [94.34% (100/106 strains), 94.34% (100/106 strains), 87.74% (93/106 strains)] in 2018 and 2019, respectively.The test strains were 100.00% (14/14 strains) resistant to the above 3 antibiotics in 2021.MIC 50 and MIC 90 values of Penicillin in 2018, 2019, and 2021 were (0.03 mg/L, 0.03 mg/L), (0.03 mg/L, 0.06 mg/L), and (0.06 mg/L, 0.06 mg/L), respectively.Among 225 GAS strains, 207 strains had drug resistance and were resistant to more than one drug.Specifically, 94.69% (196/207 strains) were resistant to Erythromycin, Tetracycline and Clindamycin.About 4.35% (9/207 strains) were resistant to both Erythromycin and Clindamycin.A total of 0.97% (2/207 strains) were resistant to Erythromycin and Tetracycline. Conclusions:The emm genotypes of GAS in children in Beijing are diverse in 2018, 2019 and 2021.The dominant genotypes are emm12 and emm1, and emm12 is the main epidemiological type.GAS strains maintain highly resistant to Erythromycin, Clindamycin and Tetracycline, and sensitive to Penicillin and other antibiotics.However, MIC 50 and MIC 90 of Penicillin shows an ascending trend.

Objective:To explore the self-management trajectory of patients with percutaneous coronary intervention (PCI) , in order to provide better guidance for disease self-management of patients with PCI.Methods:From April to December in 2019, a total of 15 patients with PCI who were treated and followed up in a Class Ⅲ Grade A hospital in Harbin and a Class Ⅲ Grade A hospital in Tianjin were selected as the research objects. All 15 patients were interviewed and recorded. Then the records were transcribed and analyzed with open coding, axial coding and selective coding according to the grounded theory put forward by Strass and Corbin, to identify the categories and core category.Results:The core category of disease self-management of patients undergoing PCI was "crisis-conscious path of PCI patient self-management", that was, the path of PCI patient self-management presented a dynamic process with the change of disease risk cognition. When patients were aware of the disease risk, they would enter the path of active health management, and when patients were unaware of the disease risk or risk cognition declines, they would enter the path of ignoring the disease self-management.Conclusions:Medical staff should pay attention to and strengthen the early postoperative risk awareness education of PCI patients; quantify patients' cognitive needs of health education and give targeted health education intervention measures; strengthen supervision and management outside the hospital, and establish the concept of lifelong self-management for patients.

Aim To investigate the effects of endocrinal petptide urocortin on subthalamic nucleus (STN) neuron''s discharge, also observe the convergence effect of UCN with dopamine (DA) and glutamate (GLU), so as to understand the regulation effects of UCN and its mechanism in Parkinson''s disease (PD).Methods Forty Sprague-Dawley rats were used in this experiment.Nerve electrophysiology method-microiontophoresis was used to observe the effects of UCN on STN neuron firing rates and firing wave.Astressin (AST, the blocker of CRF receptor 2), protein kinase A (PKA) were used to observe the effects of UCN whether via CRF-2R and PKA signal pathway.Moreover, given UCN during the period of DA and GLU, the effects of UCN on DA and GLU in STN neurons were determined.Results During the period of using the UCN, UCN could inhibit the firing rate of 82％ (27/33) STN neuron (P<0.01), and the firing discharge rates were reduced from(3.65±0.27)Hz to (2.05±0.33) Hz (P<0.01).However, the inhibitory effects of UCN in STN could be antagonized by AST.Given UCN during the period of microiontophoresis of inhibitory neurotransmitter (DA) and excited neurotransmitter (GLU), UCN could enhance the effects of DA and attenuate the excitatory effects of GLU (P<0.01).Conclusion UCN and GLU/DA in STN, UCN play inhibitory and regulated effects on STN neurotransmitters(DA and GLU)via CRF-2 receptor and PKA signal pathway.

This study was aimed to establish a method for the content determination of three components in Tribulus terrestris L., in order to compare index components of different growing periods, production places and medical parts for the scientific explanation of the harvesting time and growing places. Contents of three effective components inTribulus terrestris L., which were quercetin-3-O-β-D-gentiobioside, isorhamnetin-3-O-β-D-gentiobioside and Terrestrinone A2, were determined by HPLC. The results showed that contents of three evaluation indexes all gradually increased until June and then started reducing. The contents in all evaluated indexes were in the order of the stem and leaf > fruit > root. And the content in the root was below the detection limit. The content indexes ofTribulus terrestris L. of the Inner Mongolia were much higher than that of other regions. It was followed byShandong,Hebei andShanxi province. It was concluded that the method was simple and accurate with good repeatability and stability, which was suitable for quality control ofTribulus terrestris L.

Aim To investigate the inhibitory effects of urocortin2 (UCN2) on ventral tegmental area (VTA) nervous activity of morphine addiction rats and the mechanism. Methods Morphine addiction rats and the microiontophoresis method were used to observe the effects of UCN2 on VTA neuron′s spontaneous dis-charge changing rule, as well as the inhibitory effects of UCN2 on DA neuron′s cluster spontaneous dis-charge, to identify UCN2 and DA on the same VTA neuron. Morever, the inhibitor of corticotropin-regula-ting factor′s receptor ( CRF-2 R ) and the blocker of protein kinase A ( PKA ) , AST-2 B and H89 , were used to investigate the effects of UCN2 on VTA neuron′s of morphine addiction rats. Results UCN2 could inhibit the firing rate 82% (31/38) of the tested VTA neuron ( P<0. 01 ) , the discharge frequency changed from (20. 89 ± 2. 86) Hz to (13. 66 ± 3. 93) Hz (P<0. 01). Further, the inhibitor of PKA, AST-2B and H89 could ablolish the inhibitory effects of UCN2 . Morever, the excitatory firing of VTA neurons was at-tenuated by addition of UCN2 , while AST application could inhibit the UCN2′s inhibitory effects. Conclu-sion UCN2 could regulate the effects of VTA via PKA pathway and may thereby contribute to the improvement of drug addiction.
