1.Study of the correlation of cerebral CT and P300 in 30 patients with Alzheimer's disease
Journal of Third Military Medical University 2003;0(17):-
Objective To observe the changes of cerebral CT and auditory event related potentials (ERP, P300) for finding the effective method for the comprehensive evaluation of the patients with Alzheimer's disease. Methods Cerebral CT, P300, and Mini Mental State Examination (MMSE) were employed to assess 30 patients with Alzheimer's disease. Results Latency and amplitude of wave of P300 in patients were prolonged and decreased, respectively. Cerebral CT found an obvious atrophy in the frontal and temporal lobes of cerebra. These changes were obviously correlated with the severity of dementia. Conclusion Using cerebral CT, P300, and MMSE can offer morphometric, functional and psychological information which is helpful for precise assessment of patients with Alzheimer's disease.

Objective:To investigate the effect and mechanism of Fuzheng Jiedu Tongluofang on the expression of MMP-2,MMP-9 and invasion of human hepatoma HepG2 cell.Methods:Hepatioma HepG2 cell was treated with Fuzheng Jiedu Tongluofang.The cell viability was measured by CCK8.The invasion of HepG2 was detected by Transwell assay.The expression of MMP-2 and MMP-9 was analyzed by ELISA.Results:In the CCK8 assay,Fuzheng Jiedu Tongluofang could inhibit the proliferation of HepG2 cells at a density and time measure.In the Transwell assay,the inhibitory rate of invasion was 52.45% when treated with Fuzheng Jiedu Tongluofang at a concentration of 2.65 mg/ml. The ELISA assay indicated that the expression of MMP-2 and MMP-9 decreased significantly after treated with Fuzheng Jiedu Tongluofang(P<0.05). Conclusion:Fuzheng Jiedu Tongluofang suppressed the invasion of HepG2 with the possible mechanism of down-regulating the expression of MMP-2 and MMP-9 in HepG2.

ObjectiveTo understand the epidemiological characteristics of influenza in Jingzhou from 2016 to 2021, so as to provide scientific evidence for the formulation of influenza prevention and control policies in this region, and effectively protect people's health. MethodsData of influenza-like illness (ILI) and pathogen surveillance in Jingzhou during 2016‒2021 were collected and statistically analyzed. ResultsA total of 46 272 ILI cases were reported from two hospitals in Jingzhou City from 2016 to 2021. The difference in the constituent ratio of ILI was statistically significant among different age groups (P<0.05). A total of 12 812 specimens were collected from two hospitals for influenza surveillance. A total of 1 513 cases were RNA positive,and the positive rate of influenza virus nucleic acid detection was 11.81%. The RNA positive specimens were mainly B (Victoria), accounting for 39.33%. There were statistically significant differences in the positive rate of influenza virus nucleic acids and different types of influenza virus nucleic acids among different years (P<0.05). ConclusionThe influenza epidemic in Jingzhou peaks in winter and spring, and the new A (H1),A (H3), B (Victoria) and B (Yamagata) types alternate and mixed epidemics dominate.

ObjectiveTo analyze the epidemiological characteristics of influenza virus in severe acute respiratory tract infection (SARI) cases in Jingzhou City, so as to provide a scientific basis for the formulation of influenza prevention and control policies in Jingzhou City. MethodsSARI surveillance was carried out in two sentinel hospitals in Jingzhou City from 2018 to 2023. Respiratory tract samples were collected from cases and influenza virus nucleic acid was measured using real-time fluorescent polymerase chain reaction (RT-PCR). ResultsA total of 2 603 SARI samples were tested from 2018 to 2023, and 338 samples were positive for influenza virus nucleic acid, with a detection rate of 12.99%. The highest positive detection rate was 20.22% in 2019, followed by 14.29% in 2022, and the lowest detection rate was 7.75% in 2020. There were significant differences for the positive detection rates of influenza in each monitoring year (χ²=30.386, P<0.001). There were epidemic peaks in the five surveillance years from 2018 to 2023 except 2020. There were winter epidemic peaks during 2018‒2019 and 2021‒2022, and an obvious summer epidemic peak was also observed from 2019 to 2022. H1N1, H3N2, B-Victoria and B-Yamagata were alternately prevalent in the six surveillance years. In 2019, H1N1, H3N2 and B-Victoria were alternately prevalent with time progress, in 2021 only B-Victoria was prevalent, and in 2022 H3N2 and B-Victoria were prevalent. There was no statistically significant difference for the positive detection rates of influenza virus between different genders (χ²=0.178, P=0.673). Among the four age groups, the positive rate of influenza virus in the age group of 15‒<25 years old was the highest (40.91%), followed by the age group of 25‒<60 years old (21.31%). There were statistically significant differences for the positive rates of influenza virus among different age groups (χ²=24.496, P<0.001). ConclusionThe surveillance of SARI cases in Jingzhou City could serve as an effective supplement to the surveillance of ILI in sentinel hospitals. It is suggested to expand the surveillance scope, strengthen public education and outreach on the prevention and control of respiratory diseases, thereby providing a scientific basis for influenza prevention and control.

International Eye Science 2017;17(4):724-726
AIM: To investigate the clinical effect and complication of orthokeratology for myopia.
METHODS: From August 2014 to October 2015, 204 adolescents(408 eyes)with myopia in our hospital, were treated with orthokeratology, and followed up at 1, 3, 6 and 12mo for visual acuity, corneal curvature, axial length and so on.
RESULTS: The visual acuity was significantly improved than before wearing(P<0.05). At 1, 3, 6 and 12mo after wearing, the visual acuity were 0.52±0.12, 0.64±0.20, 0.95±0.15 and 0.97±0.12; after wearing the diopter significantly decreased than before wearing(P<0.05); at 1, 3, 6 and 12mo after wearing diopter were 1.82±0.40D, 0.96±0.20D, 0.40±0.09D and 0.25±0.06D. There was no significant difference in the corneal curvature, axial length, corneal endothelial cell density and central thickness between before and after wearing(P>0.05). After wearing the anterior corneal surface curvature radius significantly increased than before wearing(P<0.05). At 1, 3, 6 and 12mo after wearing, anterior corneal surface curvature radius were 7.90±0.21 mm, 8.20±0.22mm, 8.24±0.23mm and 8.30±0.26mm. There was no significant difference on the posterior corneal surface curvature radius and anterior chamber depth between before and after wearing(P>0.05).
CONCLUSION: Orthokeratology correcting myopia, is safe and effective with no obvious effect on corneal endothelial cells and anterior chamber depth. There is a certain scope of application for the correction of myopia.

Objective Using the information - motivation - behavior model (IMB) to intervene with the alcohol dependence patients and provide a new strategy for implementing health education. Methods Eighty-nine patients with alcohol dependence, who clinically recovered or improved after the discharge, were randomly divided into a research group and a control group. Both groups received routine health education, rehabilitation guidance and a follow-up call. The research group implemented additional IMB health education. The implementation effect on alcohol dependence scale (ADS), Michigan alcoholism screening test (MAST), and alcohol dependence prevention and treatment knowledge (self-designed questionnaire) of the two groups before and after intervention was analyzed. Results The relapse rate of the research group was lower than that the control group, which was statistically significant (P<0.05). MAST scale and ADS scale in the research group were lower than those in the control group within 3 months and 6 months after the discharge, which was significant (P values of both scales <0.05). After the 6-month follow-up, the knowledge of alcohol dependence patients in the research group and their families was significantly higher than that in the control group (P<0.05). Conclusion IMB health education implementation for alcohol dependence patients significantly reduced the relapse rate, decreased physical and psychological dependence, and improved the ability of patients to prevent and control alcohol dependence.
