Objective To investigate the value of electroencephalogram(EEG), transcranial Doppler sonography (TCD), somatosensory evoked potentials (SEP) on evaluating brain function in coma patients. Methods The brain function in 72 cases of coma(mild coma 12,moderate coma 17,open eyes coma 4 and severe coma 39 cases) were examined using EEG,SEP ,TCD and scored. Results For the first time of exam, the results of EEG in 25 cases were electrical silence; no blood stream signalthe were found in 28 cases by TCD; the wave of P14 were disappeared in 26 cases by SEP and all of them belonged to severe coma group. For the second time exam, the results of finally EEG in 17 cases were electrical silence. The results of TCD in other 24 cases were surge waves and nail waves spectra eumorphism. Brain function grading: the EEG grade V in 42 cases, grade Ⅳ in 10 cases, grade Ⅲ in 14 cases were affirmed; TCD grade V in 28 cases, grade Ⅳ in 9 cases and SEP grade Ⅲ in 27 cases were affirmed. All the 28 cases of death and the most of 25 cases abandoned treatment for many reasons were belong to severe coma group. Conclusions The more severe of coma, the higher grade of EEG,TCD and SEP, the worse of prognosis. EEG,SEP,TCD testing can provide an objective indicator not only for evaluating brain function of coma patients, but aslo for estimating prognosis.

Objective To investigate the frequency of therapy-oriented oral radiation in Nanping, China and its distribution, and to provide a basis for the rational application of therapy-oriented oral radiation and the effective allocation of resources in Nanping. Methods A questionnaire was designed to investigate the frequency of therapy-oriented oral radiation in all oral radiation diagnosis and treatment institutions in Nanping. Results In 2021, there were 54 oral radiation diagnosis and treatment institutions and 79 oral radiation machines in Nanping. The total frequency of therapy-oriented oral radiation was 61593 visits and the radiation frequency was 19.54 visits per thousand patients. The average annual frequency of medical institutions at all levels was 721.87 to 3713.25 visits per institution; the male-to-female composition ratio of frequency of therapy-oriented oral radiation in December 2021 was 50.5%:49.5%. The proportion of radiation frequency of different devices was as follows: 38.7% (intraoral dental film), 46.5% (oral panorama), 10.3% (oral computed tomography [CT]), and 4.5% (cranial photography). The proportion of radiation frequency in patients of different ages was as follows: 17.1% (0−15 years), 48.2% (15−40 years), and 34.7% (over 40 years). The frequency of therapy-oriented oral radiation grew by 77.43%, 35.18%, and 8.16% every two years from 2015 to 2021, respectively. Conclusion The frequency level of therapy-oriented oral radiation in Nanping is at the level of Class II health care. The distribution of therapy-oriented oral radiation is highly unbalanced and is related to the level of economic development. Private healthcare institutions are growing rapidly, and public healthcare institutions of grade two and above occupy the main healthcare resources. The oral panorama accounts for the most, cranial photography accounts for the least, and oral CT is the fastest-growing portion. Therapy-oriented oral radiation is predominantly performed in the young and middle-aged populations, regardless of sex. Except for intraoral dental films, the general trend is upward.

Objective To investigate the status of human intestinal parasitic diseases in Nanping City from 2014 to 2018, so as to provide reference for the development of the effective control measures. Methods Administrative villages were selected using the two-stage cluster sampling in Nanping City from 2014 to 2018, and surveillance of human intestinal parasitic diseases was performed in 5 administrative villages in each county (district) of Nanping City. Intestinal parasitic infections were detected using a modified Kato-Katz thick smear method (two smears for a single stool sample) in villagers, and the hookworm species was differentiated. In addition, the eggs of Enterobius vermicularis were detected using the adhesive tape method in children aged 3 to 6 years. Results A total of 6 317 villagers were detected in Nanping City from 2014 to 2018, and the overall prevalence of human intestinal parasitic infections was 2.15%. There was year- (χ2 = 10.53, P < 0.05) and gender-specific prevalence of human intestinal parasitic infections in Nanping City during the study period (χ2 = 17.00, P < 0.01). The prevalence of human intestinal parasitic infections increased with age, and there was age-specific prevalence of human intestinal parasitic infections in Nanping City (χ2 = 102.62, P < 0.01). A total of 945 children at ages of 3 to 6 years were detected, and the prevalence of E. vermicularis infection was 3.28%. Conclusions The prevalence of human intestinal parasitic infections is at a low level in Nanping City from 2014 to 2018, and the infection mainly occurs in villagers of advanced age and low education levels. Further comprehensive measures are required to control intestinal parasitic infections in key populations.

Objective To explore the mechanism of latent human immunodeficiency ciency virus type 1 (HIV-1) infection is unclear, especially in dendritic cells (DC).We hypothesized that DC-specific intercellular adhesion molecule-3-grabbing non-integrin (DC-SIGN) binds with HIV-1 may activate HIV-1 provirus.Methods We generated a model by transfecting 293T cells with a DC-SIGN expression plasmid and a HIV-1 5'long terminal repeat (LTR) reporter plasmid, and then stimulated the 293T cells with HIV-1 gp120 protein, wild-type HIV-1 and VSV-G-pNL4.3 pseudotype virus ( without gp120 protein).CEM-Bru cells were transfected with the DC-SIGN expression plasmid and stimulated by HIV-1 gp120 protein.Then HIV-1 replication was detected.The involvement of the ERK, p38 and NF-κB pathways signaling in this response were determined by inhibiting the pathways specifically and detecting the phosphorylation of the signaling kinase.Results The HIV-1 5'LTR was reactivated by HIV-1 gp120 in DC-SIGN-expressing 293T cells.After HIV-1 gp120 protein stimulation of the mold of CEM-Bru cells, the increasing expression of HIV-1 Tat mRNA and HIV-1 p24,which implies early and late HIV-1 provirus replication was reactivated by the HIV-1 gp120/DC-SIGN stimulation.HIV-1 gp120/DC-SIGN stimulation reactivates latent HIV-1 provirus via the NF-κB signal pathway.Conclusion HIV-1 gp120/DC-SIGN stimulation reactivates latent HIV-1 provirus via the NF-κB signal pathway.
