Abstract: Objective　To analyze the recent cluster outbreaks of imported malaria and explore the risks, challenges and countermeasures for dealing with such events during malaria post-elimination era of malaria, and to provide reference for effectively addressing the risks and consolidating the achievements of malaria elimination. Methods　The individual malaria case data from "The Information System for Infectious Disease Surveillance" and "The Information System For Parasitic Diseases Prevention And Control" were collected，and the diagnosis classification, infection source, time and space distribution of cases were analyzed. Results　From January 1 to August 11, 2022, a total of 429 malaria cases were reported nationwide, an 18.9% decrease compared to the same period last year (529 cases), all of which were imported cases. The overall weekly trend of the outbreak remained stable, but since Week 31 (July 25-31), there has been a significant increase in the number of cases, with a peak on August 5. From July 25 to August 11, 2022, a total of 162 malaria cases were reported nationwide, up 315.4% from 39 cases in the same period last year, accounting for 37.8% of the total cases up to August 11, 2022. The main source of imported infections was Guinea (95 cases, 58.6%), with most cases reported in Longgang District, Shenzhen City, Guangdong Province (30 cases), Shilin County, Kunming City, Yunnan Province (21 cases), Chaoyang District, Beijing (11 cases), and Xiaoshan District, Hangzhou City, Zhejiang Province (7 cases). Conclusions　Due to the concentration of returnees to China, several entry port cities simultaneously experienced cluster outbreaks of imported malaria, which brought immense pressure and challenges to local medical and health institutions. Health facilities at all levels need to maintain high vigilance and sensitivity, be well prepared, and avoid death and secondary transmission caused by imported cases.

Bacillus cereus B-04 antagonist to Botrytis cinerea were isolated from samples of tomato soil infected by Botrytis cinerea in Zibo, which are identified through a series of morphological and biochemical characteristics and the sequence of 16SrDNA. Aiming at enhancing the inhibitory effect of this strain, a 4.1kb DNA fragment containing ?-1,3-glucanases gene from pUC1940 was inserted into vector pBE2 and pHY300PLK to construct recombination plasmids, PBE2-glu and pHY300PLK-glu, which were transferred into Bacillus cereus B-04, resulting in a new strain named B-04-glu. Restriction enzyme digestion and ?-1,3-glucanases plate culture confirmed that B-04-glu contained a functional ?-1,3-glucanases gene. Compared to the wild strain B-04, B-04-glu had an increased inhibitory effect against Botrytis cinerea on tomato.

Objective To observe effects and mechanisms of insulin on reperfusion injury after cerebral ischemia.Methods Sixty-six male Wistar rats were used in this study.All rats were divided into 3 groups as treated group(A),control group(B) and random sham-operated group(C).Four-vessel occlusion was used to establish global cerebral ischemia reperfusion model in study groups.The treated group were divided into 5 groups(A1-A5) and intraperineally injected with biosynthetic human insulin 2 IU/(kg?d) and 50%glucose 2 g/(kg?d) for 7 days,the blood glucose was monitored in preoperative and postoperative 3,6,12,24 h,and the blood glucose was maintained between 3.5-6.5 mmol/L.These animals of control group were given with saline 2 mL/(kg?d) for 7 days in abdominal cavity.All the rats were killed in the seventh day,brain homogenate was collected for detection of neuron specific enolase(NSE)and nitric oxide(NO).The hippocampus was separated for observation of electronic microscope.Results Concentration of NSE in brain tissue in group C was significantly higher than that of group A and group B,while the level in group A was higher than that of group B.Concentration of NO in group C was lower than that of group A and group B while the level of NO in group A was significantly lower than that of group B.Electron microscope showed that the ultrastructure of sham-operated group was nearly normal,damage degree of hippocampal neuron and gliacyte and capillary was gradually worse from group A1,A2 to A4,the damage degree of group B1,B2 and B4 was serious and there was no difference among them.Conclusion Insulin can really promote recovery of the cerebral injury after ischemia reperfusion.

To evaluate the value of silicone intubation and ring-fixed method in canalicular laceration.
●METHODS: A retrospective study of 36 cases with laceration of lacrimal canaliculus. For all the patients, microscope was used to find the broken ends of the lacrimal canaliculus, and then straight insertion was performed to the distant and near broken ends through the upper and lower lacrimal points, then passed the dacryocyst to insert nasolacrimal canal and ended up in inferior nasal meatus. Thus, clinical data about forming annular support to treat laceration of lacrimal canaliculus was presented here.
● RESULTS: All 36 patients with traumatic canalicular laceration were anastomosed successfully and all patients healed without infection. The surgery went well, intubation was smoothly, all patients were followed - up for another 6mo after the stent was removed. The accidental fall off of the stent was not observed during the follow - up. During the follow - up 10 - 18mo after extubation, when the stent was removed, 32 cases (88. 9%) recovered to normal lacrimal drainage function;4 cases ( 11. 1%) remained epiphora with obstructed lacrimal passage. All cases were no lower eyelid ectropion.
●CONCLUSlON: For the patients with inferior canalicular laceration, the silicone intubation and ring-fixed method is effective, low irritation and less complication.

Combining the structural features of picotamide and linotroban, a series of N,N'-bis-(halogenophenyl)-4-methoxybenzene-1, 3-disulfonamides were designed and synthesized on the basic principles of drug design. The structures of target compounds were confirmed by IR, 1H NMR and HR-MS, and the in vitro antiplatelet aggregation activity was evaluated by Born turbidimetric method with adenosine diphosphate (ADP) as the platelet aggregation inducers. The assay results showed that twelve compounds (4b, 4f, 4l, 5b, 5d-5g, 5j, 5k, 5m and 5n) were found to have superior anti-platelet aggregation activities than the positive drug picotamide. The preliminary structure-activity relationship (SAR) has been explored.
