Objective To analyze the bibliometry of the literature of acupoint thread-embedding in treating simple obesity, and to provide references for clinic.Method By both computer and manual retrieval, the relevant literatures over the past 30 years were collected from the Chinese Journal Full-text Database (CJFD), Vip database, WanFang database. By using the SPSS 17.0 software for statistical analysis, the distribution (province or city), publication year, and journal of the literatures, supporting fund, sample size, research method, material of the thread, use frequency of the involved acupoints, and the meridians of the selected acupoints were summarized.Result The included eligible 175 articles were distributed over many provinces and cities; the publication amount had been increasing year by year; there was a variety of thread materials; the literature with supporting funds only occupied a small percentage, while the research with a small sample size occupied a comparatively large percentage, and the randomized controlled trials (RCTs) also had a small percentage.Conclusion As a common Chinese external therapy in treating simple obesity, acupoint thread-embedding has been paid more and more attention for its practical value and bright future. However, the relevant governmental department hasn’t paid enough attention to this therapy, and the low clinical research quality also makes it difficult to scientifically evaluate its clinical efficacy and safety. Therefore, more attention is required, RCTs of multicenter and large sample size are expected, and clinical research quality also needs improvement, to provide references for clinic.

The relationship between acupuncture and stress is discussed from three aspects, including is it possible for acupuncture stimulation to be a stressor, whether acupuncture will start stress reaction, and whether acupuncture effects contain some stress factors. It is believed that correct acupuncture manipulation will not cause stress response, however, under some circumstances, such as inaccurate manipulation, improper treatment or patients who are very nervous but do not receive effective intervention, acupuncture is likely to cause stress response. Acupuncture-induced stress response is totally different from acupuncture anti-stress. The possible stress factors in acupuncture effect are explored, which can provide a new angle for the research on action mechanism of acupuncture. From the view of stress to review acupuncture treatment, there are three enlightenments: emphasizing on communication between doctors and patients, avoiding over-pursuit of deqi and focusing on analysis of the body constitution.

Objective·To investigate the effects of interleukin-1β (IL-1β) on neonatal rat alveolar arrest induced by intra-amniotic injection of lipopolysaccharide (LPS). Methods·A neonatal SD rat model of bronchopulmonary dysplasia (BPD) was constructed by intra-amniotic injection of LPS in pregnant rats. The pregnant rats (E19) were randomly assigned to Saline group, LPS group and LPS+anti-IL-1β group. The lungs of the neonatal rats were randomly collected 1, 3 and 7 days after birth. Pathological changes in the lungs were observed by hematoxylin-eosin (H-E) staining, and expression of IL-1β mRNA and protein was detected by real-time PCR and ELISA, respectively. Rat bone marrow derived primary macrophage was cultured in vitro, and given LPS intervention, then genes related with IL-1β were detected through whole transcriptome sequencing. Results·Compared with the Saline group, the alveolar counts and secondary septa counts significantly decreased, and mean liner intercept significantly increased in LPS group. Moreover, the expression of IL-1β mRNA and protein in lungs significantly increased in LPS group. The LPS-induced pathological changes of lung tissues in neonatal rats were improved by anti-IL-1β. LPS could up-regulate the expression of genes including Gbp5, Ccl3, Nod2, Ccr5, Mefv, Casp4 and Ifnar1, but down-regulate Lgals9 and Gstp1. Among these genes Gbp5, Ccl3, Nod2, Ccr5, Casp4, Ifnar1 and Lgals9 could positively regulate IL-1βproduction. Conclusion·LPS can induce alveolar arrest through up-regulating the expression of IL-1β in macrophages in neonatal rat BPD model. Whole transcriptome sequencing reveals that LPS can regulate the expression of IL-1β in macrophages through several paths.

OBJECTIVETo explore the action mechanism of electroacupuncture (EA) at "Shenmen" (HT 7) and "Sanyinjiao" (SP 6) on insomnia.

METHODSThirty SD rats were randomly divided into a blank group, a model group and an EA group, 10 cases in each group. The insomnia model was made by immobilization method in the model group and EA group. After model establishment, rats in the blank group and model group were treated with fixation and no treatment was given. Rats in the EA group were treated with EA at "Shenmen" (HT 7) and "San-yinjiao" (SP 6) for 15 min, once a day for 4 days. After treatment, the level of daytime and nighttime activity, open-arm entry percentage and open-arm time percentage of elevated plus-maze test were measured; the content of noradrenaline (NE), dopamine (DA) and epinephrine (EPI) in plasma and NE, DA in thalamus and brainstem were detected by using euzymelinked immunosorbent assay method.

RESULTSCompared with the blank group, the daytime activity was increased and nighttime activity was reduced in the model group (both P<0. 05); the open-arm entry percentage and open-arm time percentage of elevated plus-maze test were both reduced in the model group (both P<0. 05); the contents of NE, DA, EPI in the plasma and NE, DA in thalamus and brainstem were increased in the model group (all P<0. 05). Compared with the model group, the daytime activity was reduced and nighttime activity was increased in the EA group (both P<0. 05); the open-arm entry percentage and open-arm time percentage of elevated plus-maze test were both increased in the EA group (both P<0. 05); the contents of NE, DA, EPI in the plasma and NE, DA in thalamus and brainstem were reduced in the EA group (all P< 0. 05).

CONCLUSIONElectroacupuncture at "Shenmen" (HT 7) and "Sanyinjiao" (SP 6) can restrain the over-activity of the sympathetic-adrenal medullary system to treat the insomnia.

To analyze influenza pathogen spectrum in Yunnan province during 2009-2014 years, and analyze HA and NA genes of influenza A H1N1. Analysis was made on the monitoring date of influenza cases in Yunnan province in recent 6 years, 23 strains of influenza virus of HA and NA gene was sequenced and analyzed by MEGA 5 software to construct phylogenetic tree. 4 times of influenza AH1N1 epidemic peak were monitored from 2009-2014 years in Yunnan Province, as the nucleic acid detection results of influenza A H1N1 accounted for 28.8% of the total. The sequencing result showed that HA and NA gene were divided into 3 groups, one was detected with H275Y mutation strains. Influenza A H1N1 is one of the important subtypes in Yunnan province and their genes have divided into three branches during the period of 2009-2014 years, the vast majority of influenza a H1N1 are still sensitive to neuraminidase inhibitors.

Objective To investigate the mutation of hemagglutinin gene and amino acid variation of influenza B.Methods Influenza B virus was isolated from throat swab samples in sentinel surveillance of Yunnan province from 2009 to 2014.HA1 gene sequence analysis was applied to determine 12 randomly-selected strains of influenza B virus.The results were analyzed,MEGA software was used to do homology comparison and HA gene phylogenetic tree was established.Results Differences on the serotype and genotype identification of influenza strains were found and it might be caused by inadequate gene mutation accumulation.Amino acid variations were found in 3 important regions of antigenic determinants in HA1 protein:ring 120,ring 150 and ring 160.The amino acid variation of position 131 in ring 120 was N131K,and in position 137 was N137H.Two strains had P187S mutation in position 187.Conclusion There are some important variations in the hemagglutinin gene of influenza B strains in Yunnan Province,with some variations being the same as vaccine strains and some being not.

Objective:To explore gene expression and metabolic capacity changes of brown adipose tissue(BAT)during different gestation periods.Methods:A normal pregnancy model was established using C57BL/6J mice, while infertile mice of the same age were served as the control group. The morphological alteration of BAT during pregnancy as well as the gene expression of uncoupling protein 1(UCP1) and other fat browning and mitochondrial marker genes were detected. Moreover, BATs from early and late gestation were selected to screen differentially expressed genes in relation to pregnancy progressing by RNA sequencing(RNA-seq), and gene ontology(GO) and Kyoto gene and gene sequencing(KEGG)were performed.Results:With pregnancy progressing, the size of BAT lipid droplets was substantially enlarged, UCP1 protein expression was decreased( P<0.01), and the fat browning marker genes(Ucp1, Dio2, and Pgc1α)and the mitochondrial marker gene CytC were downregulated( P<0.001). Additionally, a total of 1 298 distinct genes were identified by RNA-seq, 906 of which were upregulated and 392 were downregulated at later stage of pregnancy. GO and KEGG analyses revealed that the differentially expressed genes were mainly enriched in bioregulatory functional pathways such as lipid metabolism, sex steroid hormones, and inflammatory factors. Conclusion:BAT in mice showed larger lipid droplets and reduced thermogenic and metabolic capacity during late gestation, and BAT gene expression was significantly different in different periods of gestation, so reduced metabolic capacity of BAT may contribute to metabolic abnormality during pregnancy.

Objectives: . Despite the efficacy of surgical treatments, the high rate of recurrence in juvenile nasopharyngeal angiofibroma (JNA) after surgery remains an unresolved problem. The present study comprehensively analyzed the risk factors and characteristics of JNA recurrence, providing clinical guidance for reducing recurrence. Methods: . A total of 123 patients who underwent surgery for JNA between 1997 and 2019 at a single hospital were analyzed retrospectively. Univariate and multivariate analyses were used to assess the clinical risk factors for the recurrence of JNA. The relapse-free survival and annual cumulative recurrence rates were analyzed for subgroups defined according to clinical parameters. Results: . After screening, 78 of the 123 patients were included in the present study. The main risk factors associated with JNA recurrence included the year of diagnosis, tumor size, sphenoid bone invasion, Radkowski stage, surgical approach, and intraoperative bleeding. Importantly, the surgical approach and sphenoid bone invasion were independent prognostic factors affecting recurrence. Patients who underwent endoscopic surgery without sphenoid bone invasion exhibited longer relapse-free survival. In the present study, the overall cumulative recurrence rate of JNA was 38.7%, and recurrence occurred mainly in the first year after the initial surgery. Conclusion . Endoscopic surgery achieved better relapse-free survival in JNA patients, and patients with sphenoid bone invasion should be carefully explored to avoid residual JNA. The recurrence rate of JNA differed among subgroups defined based on clinical parameters and was highest in the first year after surgery. Computed tomography or magnetic resonance imaging, along with close follow-up, should be performed strictly within 1 year after the primary operation.

OBJECTIVE To determine the incidence and prognosis of olfactory,gustatory and auditory dysfunctions related to the COVID-19 Omicron strain infection.METHODS A cross-sectional investigation was performed through online questionnaires.Data of patients with Omicron strain infection from December 24th,2022 to January 2nd,2023 were collected.The visual analogue scale(VAS)was used to evaluate the self-reported olfactory,gustatory and auditory functions of patients.RESULTS A total of 869 valid questionnaires were obtained.The incidence of otolaryngology-related symptoms associated with omicron strain infection was 96.8%.The incidence of olfactory,gustatory and auditory dysfunction was 44.4%,44.2%and 10.7%,respectively.There were statistically significant differences(P<0.001)in VAS scores for olfactory,gustatory,and auditory impairments between all surveyed individuals before and after infection,as well as in the corresponding VAS scores for those who experienced these impairments.The median duration of olfactory,gustatory and auditory dysfunction were 5,4 and 3 days,respectively.CONCLUSION The incidence of olfactory,gustatory,and auditory impairments is high after Omicron infection,with most cases experiencing rapid spontaneous improvement.For the long-term symptoms,the otolaryngology doctors are responsible for exploring and developing effective intervention measures.
