Objective To explore the effects of warming-yang and tonifying-qi needling combined with electromyographic biofeedback therapy(EMGBFT)on brain image structure,surface myoelectric characteristics and neurotransmitters in patients with stroke rehabilitation.Methods A prospective research method was conducted in which 200 stroke rehabilitation patients admitted to the Third Hospital of Xingtai City from February 2021 to February 2022 were selected as the study subjects.According to the random principle,the patients were divided into a control group and an study group,with 100 cases in each group.Both groups received routine treatment for stroke,while the control group received a combination of EMGBFT.The study group received a combination of warming-yang and tonifying-qi acupuncture based on the control group,and both groups continued to receive treatment for 9 weeks.Observe the clinical efficacy of two groups of patients and compare the differences in National Institutes of Health Stroke Scale(NIHSS)scores,traditional Chinese medicine symptom scores,brain image structures,serum neurotransmitter levels,and surface electromyography levels before and after treatment,and observe the occurrence of adverse reactions.Results The effective rate of treatment in the study group was significantly higher than that in the control group(97.00％ vs.87.00％,P<0.05).After treatment,NIHSS score,traditional Chinese medicine symptom score,root-mean-square(RMS)of biceps and triceps,and synergistic contraction rate(SCR)were significantly lower than those before treatment in both groups,and the levels of cerebral blood flow(CBF)in the thalamus and frontal lobe,fractional anisotropy(FA),norepinephrine(NE),5-hydroxytryptamine(5-TH),and dopamine(DA)were significantly higher than those before treatment.After treatment,the NIHSS score(4.18±1.09 vs.6.89±1.54),traditional Chinese medicine symptom score(5.41±1.08 vs.9.46±1.55),and biceps RMS(μV:9.76±3.51 vs.16.36±3.44),triceps brachii RMS(μV:6.79±1.83 vs.10.61±2.87),and SCR[(28.08±8.73)％ vs.33.08±9.31)％]were significantly lower than those control group(all P<0.05),the CBF of the thalamus(mL·kg-1·min-1:278.97±86.32 vs.233.63±84.62),and the CBF of the frontal lobe(mL·kg-1·min-1:299.31±75.54 vs.262.81±87.18),FA(0.57±0.18 vs.0.48±0.14),serum 5-HT(ng/L:352.83±38.93 vs.306.71±32.54),NE(ng/L:160.83±17.25 vs.122.81±12.41),DA(μg/L:9.23±0.92 vs.7.36±0.71)were significantly higher than those of the control group(all P<0.05).The incidence of adverse reactions in the study group was significantly lower than that in the control group(3.00％ vs.14.00％,P<0.05).Conclusion Based on EMGBFT,the combination of warming-yang and tonifying-qi acupuncture can synergistically improve the clinical symptoms and brain image structure in stroke rehabilitation patients,and increase their serum neurotransmitter levels,with fewer adverse reactions,which is worthy of promotion.

OBJECTIVE: To survey antibiotic resistance of clinical isolates of Acinetobacter baumannii in Changsha and to investigate molecular epidemiological characteristics of carbapenem-resistant Acinetobacter baumannii. METHODS: A total of 205 non-duplicated, clinical isolates of Acinetabacter baumannii from 10 general hospitals in Changsha were collected from March 2010 to December 2010. The K-B disk diffusion method was applied for the drug-susceptibility test; a modified, double-disk synergy test was used to detect metallo-β-lactamase (MBL), and a modified Hodge test was used for the screening of carbapenemase. PCR was used to amplify carbapenemase genes (including OXA-23, OXA-24, OXA-51, IMP-1, and VIM-2) and the positive products were sequenced. Enterobacterial repetitive intergenic consensus PCR (ERIC-PCR) was used for DNA typing and test of homology. RESULTS: Of the 18 antibiotics tested, 14 had a high rate of resistance (>50% of the isolates tested), with piperacillin the highest (80.5% of strains), and cefoperazone/sulbactam the lowest (2.5%). In total, 115 carbapenem-resistant Acinetobacter baumannii strains were confirmed, but their MBL phenotype and genes were all negative. Seventy-one positive strains were detected by the modified Hodge test, among which 64 strains were OXA-23-positive. All the 115 strains were positive for the amplification of the OXA-51 gene, and no strain was found which carried OXA-24 or OXA-58 gene. Seven genomic types were included in the 115 Acinetobacter baumannii. The major prevalence types were Type B ( 72 strains) and Type A (19 strains). CONCLUSION Multiple drug resistance of clinically isolated Acinetobacter baumannii is a serious problem in Changsha. Production of OXA-23 and OXA-51 carbapenemases is an important mechanism of resistance to carbapenem antibiotics, and there is prevalence of the same clones in these carbapenem-resistant strains.

Objective: To summarize the experience of the diagnosis, treatment and effects of the cases with coexistence of first branchial cleft anomaly(FBCA) and microtia with congenital aural atresia or stenosis(external auditory canal stenosis, EACS). Method: This was a retrospective study. The clinical data of 5 patients with microtia and EACS in Beijing Tongren Hospital of Capital Medical University from October 2015 to March 2018 were collected, including 3 males and 2 females, aged from 5 to 28 years. The clinical characteristics, imaging findings, treatment methods and effects of 5 patients were analyzed. Result: The 5 cases were all coexistence of EACS and FBCA, three of who associated with cholesteatoma of external auditory canal. CT showed external auditory canal stenosis with soft tissue shadow, sometimes gas or bone septum found inside, filling in the external auditory canal, combined with canal bone destruction irregularly. All patients underwent surgical resection of FBCA, 3 patients accompanied by cholesteatoma resection and canalplasty. The postoperative follow-up ranged from 10 to 39 months, and no recurrence of infection was observed. Conclusions EACS and FBCA both result from maldevelopment of the first branchial cleft. These two malformations, FBCA and EACS with or without cholesteatoma, can occur simultaneously, in which situation CT shows external auditory canal stenosis with soft tissue shadow inside. These patients underwent surgical resection of FBCA combined with cholesteatoma resection with good result.
