Objective To evaluate the anti-human respiratory syncytial viurs ( hRSV ) effect of aminoglucomannan ( AGM) in mice.Methods BALB/c mice infected with hRSV were randomly divided into AGM and konjac glucomannan ( KGM) groups with 54 in each.Then, mice in AGM group and KGM group were subdivided into three groups and treated with different doses of AGM or KGM as 2.5 μmol/L, 0.25 μmol/L or 0.025μmol/L.Each subgroup was further divided into 3 groups with 6 in each according to administration intervals of AGM or KGM as 8 h, 12 h or 24 h.All the mice are sacrificed at 72 h.The general condition of the mice was observed everyday.Reverse transcription-polymerase chain reaction ( RT-PCR) was used to detect the expression of hRSV fusion protein ( F) mRNA in the lung tissue of the mice. HE staining method and immunohistochemistry technique for intercellular cell adhesion molecule-1 ( ICAM-1) expression in the lung tissue were used to evaluate the inflammation in the lung tissue.ANOVA for randomized block design was used to examine the influence of dose and administration intervals on the expressions of hRSV F mRNA and ICAM-1.Results Reduced activity and asthma were observed in 16 mice in the KGM group, but not in the AGM group.And two mice in the KGM group died at d3, but there was no death in the AGM group.RT-PCR showed that the levels of hRSV F mRNA in lung tissues were 0.49 ±0.21 in AGM group and 0.88 ±0.06 in KGM group (t=6.71, P<0.05).HE staining of lung tissue showed that the inflammation in KGM group was more serious than that in AGM group.The expression of ICAM-1 in AGM group was much lower than that in KGM group, and there was statistical difference between two groups (t=13.88, P<0.05).In AGM group, the levels of RSV F mRNA and ICAM-1 decreased with the increase of AGM’s concentration and rised with longer administration intervals (P<0.05), but these were not observed in KGM group (P>0.05).Conclusion AGM can alleviate the inflammation of lung tissue in mice infected with hRSV in a dose and time-depandent manner.

Objective To investigate the short-term efficacy and security of combined treatment of iodine-125 seeds and transeathether arterial chemoembolization in liver neoplasms. Methods Transcathether arterial chemoembolization underwent in experimental group (28 cases) with liver neoplasm. The treatment plan was formulated with treatment planning system and a median of 25 seeds per patient (range, 15--40 seeds) were implanted under CT or B ultrasound guidance in 2 weeks after the procedure. Transcathether arterial ehemoembolizafion underwent after the implanted regularity. Blood routine and liver function were detected before and after the procedure. X ray check and abdomen CT scan were performed each 2 months. Control group (32 cases) were treated with transcathether arterial chemoembolization alone. Analysis of variance and Chi-square test were used for statistics. Results All seeds were released to the target places successfully and no seed was found to be lost or migrated in experimental group. Transient elevation of the serum ALT and AST but recovered in 2 week. WBC, Hb, IgA and IgG were showed no significant changes. The severe complication was not found in those eases. The responsive rate of tumor was 75.0% (21/28), 37.5% (12/32) in experimental group and control group, respectively(X2 = 8.485,P = 0.004). The survival rate of 6 months was 92.9% (26/28), 75.0% (24/32) in experimental group and control group, respectively(X2=2.263,P=0.132). The surviral rate of 12 months was 72.0% (18/25), 43.3% (13/30) in experimental group and control group, respectively (X2 = 4.556, P=0.033). Conclusion It is simple, feasible, safe and short-termly effective for liver neoplasms in treatment combined iodine-125 seeds implantation with transcathether arterial chemoembolization.

Objective To explore the effect of hospital-community integration follow-up pattern on medication compliance in patients with mental disorder. Methods From January 2016 to January 2017, 96 patients were treated effectively with systemic therapy in psychosomatic department and TCM WM department, and 96 discharged mental disorder patients were treated with brief psychiatric rating scale (BPRS) ≤ 28. The patients were randomly divided into 48 cases in the intervention group and the control group; both groups were standardized medication; control group received an outpatient referral, intervention group combined with medical doctors in our hospital and community doctors for one year follow-up intervention. Observed the condition of illness and medication compliance after six months and one year intervention between two groups, compared the patient recurrence rate of one year after discharge. Results BPRS score of intervention group was significantly lower than control group (P＜0. 01), the difference was statistically significant, while intervention group had higher compliance than control group (P＜0. 01), and the difference was statistically significant. Recurrence rate (20. 83％) of intervention group was significantly lower than control group (38. 78％) ( 2 = 4. 03, P＜0. 05), the difference was statistically significant. Conclusion Hospital-community integration follow-up has positive effect on stabilizing patients with mental disorder and improving compliance and decreasing relapse rate.

Objective: To explore the relationship between visual acuity and physical fitness of university freshmen, so as to provide reference for myopia prevention and control for freshmen. Methods: From October to November 2022, 2 160 college freshman without majoring in public safety administration, selected from Guangxi Police College in 2022 by using the stratified cluster random sampling method, were reviewed for the results of visual acuity test and physical fitness scores. The physical fitness indices were evaluated by using the Z scores of physical fitness test scores, and the strength of association between the level of physical fitness index and myopia was analyzed by using Logistic regression model. Results: Among 2 160 college freshman without majoring in public safety administration, 917 (42.5%) students were diagnosed screening myopia, including 66 (3.1%) cases of high myopia, 383 (17.7%) cases of moderate myopia and 468 (21.7%) cases of mild myopia. The differences in the distribution of visual acuity tests among students with different physical fitness indices, body mass index, and gender were statistically significant ( Z/H=54.50, 49.53, 15.51, P <0.01). Low level and low middle level physical fitness indices were associated with screening myopia among freshmen[ OR (95% CI )=2.81(1.93-4.08),1.87(1.38-2.54)], and low level physical fitness indexes were associated with high myopia [ OR (95% CI )=7.22(2.33-22.32)] ( P <0.01). Conclusions Screening myopia among college freshman without majoring in public safety administration is related to physical fitness, and low level and low middle level physical fitness index are risk factors for myopia. Improving the level of physical fitness might be effective in preventing myopia.

Objective:To evaluate the new model of group screening combined with opportunistic screening for the diagnosis and treatment of gastric cancer.Methods:Group screening combined with opportunistic screening was used for gastric cancer screening. (1) Group screening. Cluster sampling was used to screen gastric cancer by endoscopy in high-risk population (aged 40-<70 years) of rural residents in Weihai from July 2017 to December 2020, and biopsy was obtained for histopathology if necessary. Main collection parameters included the detection rate of advanced gastric cancer, early gastric cancer and high-grade intraepithelial neoplasia (HGIN). (2) Opportunistic screening. The changes of the detection rates of early gastric cancer in opportunistic screening in 2 hospitals in Weihai area were observed during the same period of time.Results:(1) In group screening, from July 2017 to December 2020, the first batch of 8 000 cases of gastric cancer screening were completed. The cases of advanced gastric cancer, early gastric cancer and HGIN were 36, 28, and 62, respectively. The detection rates of gastric cancer and early gastric cancer were 0.80% (64/8 000) and 43.75% (28/64), respectively. The proportion of early gastric cancer+HGIN who received endoscopic submucosal dissection (ESD) was 77.78% (70/90), and the rate of curative resection was 100.00%(70/70). (2) Opportunistic screening: from July 2017 to December 2020, the annual early gastric cancer detection rates in opportunistic screening in Wendeng District Traditional Chinese and Western Medicine Hospital were 16.67% (1/6), 20.00% (3/15), 23.53% (4/17), and 33.33% (6/18) in the consecutive 4 years, respectively. The annual detection rates of early gastric cancer in opportunistic screening in Ru Shan Peoples Hospital were 14.74% (14/95), 23.80% (60/252), 25.49% (65/255), and 24.04% (50/208), respectively. The detection rates of opportunistic screening for early gastric cancer in hospitals in Weihai city increased year by year.Conclusion:In areas with high incidence of gastric cancer, a certain scale of group screening can lead to a wider range of opportunistic screening, resulting in the increase of the detection rate of early gastric cancer. The new model of diagnosis and treatment of gastric cancer is worth recommendation.
