Objective To observe the therapeutic effect of the integration of Longji-Huoluo pill and mild manipulations Tuina therapy for the teenagers with lumbar intervertebral disc protrusion. Methods Eligible teenager patients with lumber intervertebral disc protrusion were randomly classified into two groups according to the single blind method and the treating sequence, 69 patients in the treatment group and 58 patients in the control group. The Longji-Huoluo pill and mild Tuina manipulations were adopted on the basis of the convertional treatment in the treatment group. While ibuprofen sustained release capsules and mecobalamin were given to the control group beside the convertional treatment. Both groups were treated for 4 weeks. The CT examinations were applied before and after the treatments to observe the absorption of the prolapsed lumber intervertebral disc. The Visual Analogue Scale (VAS) was used to test the pain degree and to estimate the clinical effect. Results The VAS scores in the treatment group (4.03 ± 1.67 vs. 5.41 ± 1.55, t=10.121) and the control group (3.61 ± 1.34 vs. 5.96 ± 1.71, t=11.086) after treatment were significantly lower than those before treatment (P<0.05). The sagittal diameters of the prominence in the treatment group (2.12 ± 1.89 mm vs. 4.62 ± 0.34 mm, t=2.281) after treatmentwas significantly lower than that before treatment (P<0.05). The total effective rate of the treatment group was 87.0%(60/69), and the control group was 72.4%(42/58). Statistical significance was detected on the difference of the two groups (U=1.913, P=0.043). Conclusions The integration of manipulations can effectively relieve the pain and can return the prominent disc. The therapeutic effect is considered equivalent to western medicine.

Abstract: Objective To summary and analyze the epidemic situation of imported malaria and the prevention and control measures implemented during the new crown pneumonia epidemic in Shenzhen, so as to provide reference for the prevention and control of imported malaria under COVID-19 epidemic. Methods　The data on the prevention and control of malaria epidemic in Shenzhen from 2017 to 2021 were collected for analyzing the epidemic situation of malaria, measures taken and the effect of prevention and control with descriptive epidemiological methods. Results　From 2017 to 2021, a total of 104 confirmed malaria cases were reported in Shenzhen, all of which were imported from abroad. 97.1% were imported from Africa, mainly falciparum malaria, accounting for 80.8%. The age of onset was mainly young adults, the age group 20-49 years accounted for 81.7%, and most of the patients were overseas migrant workers, accounting for 59.6%. Imported malaria cases were reported in each month, the most was 13 cases in July, then 12 cases in September. From 2017 to 2021, 709 mosquito trap lamps were placed, and 3 523 mosquitoes were captured, with an average mosquito density of 2.60 per lamp and night. Anopheles were not found, and the dominant species were Culex quinquefasciatus. During the outbreak of COVID-19, Shenzhen has implemented a series of measures in terms of improving the working mechanism of multi-departmental cooperation and joint defense, strengthening screening and monitoring, personnel training, mosquito vector control, and material security, so as to achieve early detection, early transfer, early isolation and early treatment. Conclusions　A series of measures have been comprehensively implemented to prevent and control imported malaria in Shenzhen while preventing and controlling imported new coronary pneumonia, and achieved positive results. It has realized the timely identification of cases and effective treatment, and prevented the occurrence of severe and fatal malaria cases, as well as halting the spread and spread of malaria outbreaks.

This technique has been widely used to test toxicity of chemicals with the advantages of low cost, high sensitivity, simple to operate and simultaneous to detect multi-endpoints. The main methodology, technical characteristics and the status of world-wide application of this technique are reviewed in this paper. Based on the urgent environmental problems in China, the prospects to use this method for monitoring toxicity of mixed pollutants in wastewater are put forward.

Objective To introduce the Chinese version of short Falls Efficacy Scale International (short FES-I) and test its reliability and validity in patients with cerebral infarction. Methods The English version and the traditional Chinese version of short FES-I were ob-tained from the Prevention of Falls Network Europe, and the simplified Chinese version was developed after a further revision. A sample of 105 inpatients with cerebral infarction from December 2014 to May 2015 were recruited from 2 tertiary hospitals in Tianjin. They were in-vestigated with the simplified Chinese version of short FES-I, modified Falls Efficacy Scale (MFES), Generalized Anxiety Disorder-7 (GAD-7) and Patient Health Questionnaire-9 (PHQ-9). At the same time, the laboratory indexes of the patients were collected. Results The Cronbach'sαcoefficient of short FES-I was 0.98 and the score of short FES-I was negatively correlated with MFES (r=-0.41, P<0.001). Short FES-I was correlated wtih GAD-7 score (r=0.52, P<0.001), PHQ-9 score (r=0.46, P<0.001) and the level of C reaction protein (r=0.21, P=0.032), but uncorrelated with other laboratory indexes (P>0.05). There was significant difference in the score of short FES-I be-tween the patients with or without falling. Conclusion Short FES-I is valid and internal consistant, and can be used as an assessment tool to screen fear of falling among patients with cerebral infarction.
