Objective: To study the characteristics of P300 and topographic dist ribution mapping in obsessive-compulsive patients. Methods: The P300 and topog raphic distribution mapping were recorded in 36 patients, using a Bneuro Galileoinstrument. Results: Compared with normal subjects, the wa ve patterns of obsessi ve-compulsive patients were unstable; the frontal wave variation and dissymmetry between the two sides was 63.9%; the N2 and P3 latency was prolonged; the P2 an d P3 amplitude was decreased; the P3 topographic distribution mapping was uneven ly distributed, the normal high amplitude in the parietal region was absent. For the patient group, energy levels below grade 5 in the left brain area, the fron tal area, and for both were 42.3%, 30.3%, 15.15% respectively. Conclu sion: P300 and topographic distribution might be served as an objective index for reflectin g cognitive activity in obsessive-compulsive patients.

OBJECTIVE:To analyze the features of risperidone-induced leucocytopenia ADR.METHODS:Twenty-one ADR cases of risperidone-induced leucocytopenia reported by our hospital were collected and analyzed during 2004-2015.The characteris tics of risperidone-induced leucocytopenia were discussed.RESULTS:Among 21 patients,there were 10 male and 11 female.The age was from 15 to 72 years old.Nine cases of patients were 31-40 years old (42.9％).Most of the original disease was schizophre nia.Incubation period of leucocytopenia caused by risperidone was (28.6 ± 21.4) d.Patients had no discomfort complain when leucocytopenia occurred.The lowest white blood cells reported was(3.1 ± 0.5)× 109 L-1.The leucocytopenia were improved after reduc tion,drug withdrawal and symptomatic treatment.CONCLUSIONS:Patients usually have no body discomfort complain when risperidone-induced leucocytopenia appears.Doctors should moniter ADR regularly,identify it earlier and treat carefully.

Objective To investigate the effects of dexmedetomidine (DEX) on the mRNA expression of triggering receptor expressed on myeloid cells 1 (TREM-1) in peripheral blood mononuclear cells of rats with acute obstructive suppurative cholangitis (AOSC).Methods Sixty healthy male Wistar rat models of AOSC induced by complete common bile duct ligation and injection of E.coli into the bile duct through an intubation tube were replicated successfully.After modeling,the peripheral blood was collected and mononuclear cells were isolated and cultured.According to random number table method,the mononeuclear cells were divided into model group (no drug added in culture of mononuclear cells) and low,medium and high dose DEX groups (final concentrations 0.4,0.8,1.2 μg/L DEX were in low,medium and high DEX mononuclear cell cultures,respectively).After the mononuclear cells were cultured for 24 hours,the levels of tumor necrosis factor-α (TNF-α),interleukins (IL-1 and IL-6) in the supernatant of the cultured mononuclear cells were detected by enzyme linked immunosorbent assay (ELISA).The level of C-reactive protein (CRP) was detected by immunity transmission turbidimetry.The expression of TREM-1 mRNA in the mononuclear cells was detected by reverse trantscription-polymerase chain reaction (RT-PCR).Results Compared with the model group,the levels of TNF-α,IL-1,IL-6,CRP were decreased,the TREM-1 mRNA expressions were down-regulated in the different DEX dose groups,and the degrees of descent in medium and high dose groups were more significant than those in low dose group [TNF-oα (ng/L):95.5±8.6,88.9±5.3 vs.131.1 ± 14.2;IL-1 (ng/L):53.5±8.3,48.3 ± 6.7 vs.73.7 ± 12.8;IL-6 (ng/L):266.9±26.2,252.1 ± 17.7 vs.349.9±40.4;CRP (ng/L):4.3 ± 1.1,3.9 ±0.7 vs.5.6 ± 1.7;TREM-1 mRNA (A value):0.43 ± 0.18,0.39 ± 0.16 vs.0.65 ±0.25,all P ＜ 0.05].Conclusion DEX can down-regulate the expression of TREM-1 mRNA and inhibit the formation and secretion of inflammatory factors TNF-α,IL-1,IL-6 and CRP in peripheral blood mononuclear cells of rats with ASOC.

Objective To understand the health literacy status,influencing factors and demand carrying out the health education based on the mobile terminal among college students to provide a new idea for formulating and implementing the health literacy promotion plan for university students.Methods The multi-stage stratified cluster random sampling method was adopted to extract 1 949 students from partial universities in Nanjing City and conduct the investigation by adopting the Rapid Estimate System of Health Literacy and Health Education Demand Based on the Mobile Terminal Questionnaire of College Students.The influence factors were analyzed by using the univariate analysis and ordinal multi-classification Logistic regression analy sis.Results The university students with high,marginal and low health literacy level accounted for 31.3％,48.9％ and 19.8％ respectively.The proportions of the students with high health literacy in the four dimensions,including health knowledge,health behaviors,health skill and health status,were 57.9％,18.3％,61.0％ and 44.5％ respectively.The ordinal multi-classification Logistic regression analysis showed that the major influence factors affecting the health literacy of university students were gender,education background of mothers,majors,grades,electively taking the health education course.81.2 ％ of university students wanted to or urgently wanted to understand the health literacy knowledge.The main route getting the health literacy knowledge by the university students was network(83.8％).91.8％ of students were willing to learn the health literacy knowledge through mobile terminal.87.1％ of students believed that the WeChat was suitable to learn the health knowledge,81.3％ of students hoped to use the WeChat platform for learning the health knowledge,73.8％ of students hoped the Wechat to push the health knowledge with the modes of words combined with images and video.It was recommended that the health knowledge pushing for 1-3 times per week was suitable.Conclusion The health literacy of university students is at the marginal level.The health behaviors literacy is most lacking and the demand for the health education based on the mobile terminal is stronger.The health literacy intervention of university students should sufficiently apply the new media platform superiority and the emphasis should be placed on the populations of males,low education background mothers,non-medicine major,low grade and without electively taking the health education course.

Objective: To study the efficacy and safety of Cefpodoxime proxetil granules in the treatment of acute bronchitis in children. Methods: One hundred and sixty children of the First People′s Hospital of Nanning from June to December 2018 with acute bronchitis were randomly divided into cefpodoxime group and cefaclor group, with 80 cases in each group.All patients received routine treatment.On this basis, 80 patients in the cefpodoxime group received oral Cefpodoxime proxetil granules 5 mg/kg (not more than 100 mg/time), twice a day; 80 patients in the cefaclor group received oral Cefaclor.The granules were 10 mg/kg (not more than 250 mg/time), 3 times a day, and the course of treatment was 5 days.The clinical efficacy and adverse reactions were observed. Results: The cure rate and effective rate of Cefpodoxime group were 91.3% (73/80 cases) and 95.0% (76/80 cases), respectively, while the cure rate and effective rate of Cefaclor group were 66.3%(53/80 cases) and 81.3%(65/80 cases), respectively, and the differences between the 2 groups were statistically significant (χ²=14.94, 7.23, all P<0.05). Sixty-three strains of pathogenic bacteria and 66 strains of pathogenic bacteria were obtained in Cefpodoxine group and Cefaclor group, respectively, and the detection rates of bacteria in the 2 groups were 78.75% and 82.50%, respectively.There was no significant diffe-rence in the number of bacterial strains and strains detected in each group (χ²=0.36, P>0.05), but the total bacterial clearance rate in Cefpodoxine group was 88.9%(56/63 cases) while the bacterial Clearance rate in Cefaclor group was 74.2%(49/66 cases), and the difference between the 2 groups was statistically significant (χ²=4.57, P<0.05). In particular, the bacterial clearance rate in Cefpodoxine group to Streptococcus pneumoniae, Staphylococcus aureus and Klebsiella pneumoniae were significantly higher than those in Cefaclor group, while the bacterial Clearance rate of Proteus and Escherichia coli were lower than those in Cefaclor group.The incidence of adverse reactions in Cefpodoxine group and Cefaclor group were 5.0% and 3.8%, respectively, with no significant difference (P>0.05). Conclusions The clinical effect of Cefpodoxime pro-xetil granules in treating children with acute bronchitis is more significant than that of Cefaclor.It has high safety and no serious side effect.
