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.

Objective To analyze the relation between ~(99)Tc~m-DTPA renal dynamic imaging and pathological changes in patients with lupus nephritis (LN).Methods Ten normal control and 29 patients with LN underwent ~(99)Tc~m-DTPA renal dynamic imaging.The LN patients were divided into two groups:silent LN (SLN) group,18 patients;and obvious LN (OLN) group,11 patients.For each case,glomerular filtration rate (GFR),peak time (t_p),half excretion time (t_(1/2)) and the excretion rate at 20 min (R_(20)) were calculated.Assessment of renal function on the scintigraphic images was evaluated by nuclear medicine physicians.The t-test,Fisher'exact probability and R×C association were used for data analysis.Results There were significant differences between normal people and two goups of LN in tp(t=5.3,9.3,both P＜0.05),t_(1/2)(t=6.9,12.0,both P＜0.05)and R_(20)(t=10.1,12.1,both P＜0.05).As to GFR,there was significant decrease in OLN patients(t=4.1,P＜0.05),but not in SLN patients(t=1.7,P＞0.05).Diagnoses of renal function by renal dynamic imaging were compared with the renal pathological changes (r=0.2273,P＜0.05).Conclusions ~(99)Tc~m-DTPA renal dynamic imaging is useful for evaluation of the early stage renal function for LN patients and to diagnose LN patients with no symptom of renal impairment.It may help to assess the degree of renal parenchymal damage while obviating the need for renal biopsy in these patients.

Objective To detect levels of serum platelet activating factor(PAF),thrombomodulin(TM) and white blood cell(WBC),platelet count(PLT) in neonates with meconium aspiration syndrome(MAS),and observe changes of mediators of inflammation and function of endotheliocute.Methods All cases were taken vein blood in 24 h and 72-96 h after birth.Surm PAF and TM were detected by EILSA technique,at the same time,blood cell counts were determined.Results PAF and WBC in neonates with MAS increased,which were relevant to the patients′ condition.TM of neonates with MAS increased significantly,especially in 72-96 h after birth and(aggrava)-ted with the patients′ condition.Conclusion Neonates with MAS have inflammatory reaction and injured endotheliocyte,which are(inte)-raction.

Objective To determine chromosomal localization of the primary gout susceptibility gene in a pedigree.Methods The clinical data and the peripheral blood samples were collected in the pedigree members and the genomic DNA was extracted from peripheral blood.A genome-wide screening was performed using 400 micro-satellite DNA markers in this family,and linkage analysis was used to determine the chromosomal location of the primary gout susceptibility gene.Results Linkage analysis showed that the maximum LOD score reached 1.50 at marker D4S1572 (at recombination fraction?=0.00).Conclusion Since D4S1572 is localized at 4q25,the primary gout susceptibility gene of this pedigree is localized at 4q25.

AIM: To investigate the influence of He-Ne laser on connective tissue growth factor (CTGF) expression and collagen formation of fibroblast in filtration site after trabeculectomy in rabbit, and to discuss the mechanism for preventing scar formation with He-Ne laserin vivo.METHODS: The upper nasal limbus area next to the upper rectus muscle in right eyes Received 10 minutes He-Ne laser irradiation (200mW/cm2) every day for three days, the left eyes served as control. Twenty-four hours after the last irradiation, both eyes of the rabbits were took trabeculectomy surgery. The expressions of CTGF in the filtration area were tested on the 7th, 14th and 28th day after surgery and collagen density was tested on the 14th and 28th day after surgery. Each of the time point had 7 rabbits. RESULTS: The expression of CTGF was lower than that of the control group's on the 7th and 14th day after trabeculectomy surgery (P=0.01, P=0.005). When examined on the 14th and 28th day, the collagen density of irradiation group were significantly lower than that of the control group's (P=0.013, P=0.01).CONCLUSION: Pretreating the filtration area with 200mW/cm2 He-Ne laser may be helpful in preventing scar formation after trabeculectomy in rabbit, possibly due to downregulation of the expression of CTGF and collagen synthesis in fibroblasts. He-Ne laser may be developed into a new scar preventing method in filtration surgery.

Objective: To dynamically analyze the discipline status, influence factors and key issues of Chinese Journal of Hepatology from 2010 to 2016 and explore the development rules of citation indexes. Methods: We collected information published by the China Institute of Scientific and Technological Information [China Science and Technology Journal Citation Report (Core Edition)] and Wanfang Database Periodicals statistical analysis platform from 2010 to 2016. A bibliometric analyses on article volume, citation frequency, citation rate, h-index, ratio of fund-aided papers, periodical influence, key number published period, number of relevant articles, and so on were analyzed for annual’s impact factor. Results: According to the data released by the China Institute of Science and Technology Information, from 2010 to 2011, the impact factor of Chinese Journal of Hepatology was at leading level in the field of internal medicine and ranked sixth in the Journal of Internal Medicine. From 2012 to 2016, the overall comprehensive assessment score and citation frequency score of Chinese Journal of Hepatology were ranked first in the Journal of Gastroenterology. Core impact factors kept the discipline ahead. Indexes such as immediacy index, h- index, cited half-life and all other indicators were increased. Citation rate was >90% and cited issue number had greatly increased. Conclusion Chinese Journal of Hepatology has a leading position in the Journal of Gastroenterology and credited by inland readers and authors of digestive and infectious fields. It has played a positive role in promoting the development of the discipline.
