OBJECTIVETo understand the comorbid characteristics and distribution of combined treatment of Chinese and Western medicine in depressive patients.

METHODThe descriptive statistic method and association rule were used to analyze the data from 19 general hospitals with 3-A level in China.

RESULTAmong the depressive disorder, the most frequent co-morbid physical diseases included hypertension (24.67%), coronary heart disease (16.10%) and cerebral infarction (12.89%), and the proportion of comorbid changes with the increasing age, from 6.51% to 12.55%, 16.33% and 12.47% for hypertension; from 2.79% to 5.69%, 10.17% and 14.22% for coronary heart disease; from 3.72%, 6.27%, 7.70% and 12.25% for cerebral infarction. The use frequency of the antidepressants is 77.18%, and the use frequency of flupentixol & melitracen is 20.95%. The use frequency of Huoxue Huayu Tongluo of traditional Chinese medicine is 59.97%, with that of 27.91% for Ginkgo biloba extract The combined use frequency of Huoxue Huayu Tongluo of TCM and the antidepressants is the highest, especially for the combined use of Shuxuening injection and fluoxetine.

CONCLUSIONThe most frequent comorbid diseases of depression include three kinds of diseases, such as hypertension, coronary heart disease and cerebral infarction, and its proportion gradually increased with the growth of age. The single use frequency of flupentixol & melitracen and G. biloba extract is the highest, while the combined use of Shuxuening injection and fluoxetine is the highest.

Abstract: Objective　To analyze the drug resistance of Staphylococcus aureus in blood samples of children and adults from 50 hospitals in Shandong Province, and to understand the drug sensitivity characteristics of Staphylococcus aureus bloodstream infection (BSI), so as to provide reference for clinical experience. Methods　The distribution and drug resistance of Staphylococcus aureus isolated from blood samples from 50 hospitals in Shandong province from 2017 to 2020 were analyzed based on the Cooperative Research Network of Pediatric Bacterial and Fungal Resistance Monitoring in Shandong Province. Meanwhile, the drug sensitivity characteristics of Staphylococcus aureus were divided into children group (<14 years old) and adult group (≥14 years old). The data were analyzed by Whonet 5.6 and SPSS 22.0 with reference to CLSI 2021 M100 document standard judgment results. Results　A total of 3 661 Staphylococcus aureus strains were collected from 50 medical institutions in Shandong Province, including 675 in 2017, 870 in 2018, 1 080 in 2019, and 1 036 in 2020. The drug resistance rates of multiple antibiotics in blood culture methicillin-resistant Staphylococcus aureus (MRSA) group and methicillin-sensitive Staphylococcus aureus (MSSA) group were significantly different (P<0.05). There were significant differences in antibiotic resistance rates between adult group and children group (P<0.05). The overall detection rate of MRSA was 27.5%, and no staphylococcus aureus strains resistant to vancomycin, linezolid and tigecycline were found. Conclusion　The detection rate of MRSA strains decreased continuously and increased by 2020. The detection rate of MRSA in adult group was lower than that in children group, suggesting that we should pay attention to the monitoring of bacterial resistance in children group, to the management of multiple resistant bacteria and rational use of antibacterial drugs.

AIM: To explore the effect of early posterior approach vitrectomy in the treatment of penetrating ocular trauma with intraocular foreign body.METHODS: Totally 10 cases of penetrating ocular trauma with intraocular foreign bodies(IOFB) in the past two years were included.Emergency vitrectomy, intraocular foreign body removal and silicone oil tamponade were performed by the same surgeon.Antibiotics and steroids were given after surgeries.Retinal photocoagulation was done according to fundus conditions after surgeries.RESULTS: One patient combined with preoperation endophthalmitis and severely damaged retina failed to recover, eventually came to phthisis bulbi.Vitrectomy and IOFB removal were all successfully performed in the other patients.The postoperation follow-up time was 3-18mo.Two of the patients received secondary vitrectomy and silicone replacement surgeries due to recurrent retinal detachment.The remaining patients had no further bleeding with intraoclar pressure(IOP) 8-21mmHg.At the last follow-up, three of them gained best corrected visual acuity better than 0.1, two patients had visual acuity of 0.01 to 0.1 and four patients had poor visual acuity of light perception to FC/50cm because of macular damage.The patient with phthisis bulbi had no light perception.CONCLUSION: Early vitrectomy, foreign body removal and silicone oil tamponade is an effective treatment for patients with penetrating eyeball injury with IOFB.

Objective To understand the demands of African students on the China?Africa malaria prevention training pro?grams as well as explore further suggestions on the student selection and course content design. Methods A self?administered questionnaire survey was conducted,and all the students who attended in the malaria prevention training courses in 2014 and 2015 were included. The Chi?square test was conducted to analyse the correlations between professional backgrounds ,work stat?ues and training needs. Results A total of 161 individuals were sampled eventually. These participants were trained in either English(58.4%)or French(41.6%). Most of the participants were male(69.3%),the major of them were mainly clinical tech?nology specialty(40.0%),and most of them worked in malaria area within 10 years(56.4%). Moreover,48.2%of the partici?pants used more than 76%of total work time on malaria control,and more than 80%worked in national or provincial/municipal level. The working areas of these participants were focused on clinical field(41.4%)and official field(29.9%),and only a few of them were from research positions(11.9%). The most needed course content in malaria training was strategy and epidemiolo?gy knowledge for malaria prevention and control(65.5%),while clinical workers were most needed to be trained(39.2%). The participants who came from French speaking countries preferred strategy training(χ2=12.528,P<0.01),and those worked in the national level were aslo more likely to choose strategies training course(χ2=10.508,P<0.05). Conclusions Currently, the China?Africa malaria prevention training programs could basically satisfy African students’needs. However,more aimed courses should be designed according to their professional backgrounds,national situation,work experiences on malaria con?trol,and institutional levels.
