Abstract: Objective To compare the screening effects of RDT, microscopy and PCR for malaria among residents in low
malaria areas and elimination areas, and to investigate the presence of malaria in residents of border Villages in Cangyuan Va
County and asymptomatic infections in surrounding areas, providing a basis for preventing re-introduction of malaria after
elimination. Methods From August 2020 to March 2021, the fingertip blood of the investigated subjects was collected from
three survey sites in the border area between China and Myanmar, namely Banlao Township in Cangyuan Va Autonomous
County of Lincang City, Banwai District, Mengmao County, the Second Special Zone of Shan State, Myanmar, Yongmo and
Dayan Township, Nandeng Special Zone, the Second Special Zone of Shan State, Myanmar. The malaria parasite antigen
detection test kit, malaria parasite microscopic examination, fluorescent quantitative PCR and nested PCR were used to detect
the asymptomatic infection of malaria parasites. Results A total of 1 040 blood samples were collected, including 606 from
China and 434 from Myanmar, with 506 males and 534 females. Among them, , there were 51 individuals aged 0 to <5 years,
283 aged 5 to < years, 187 aged 15 to < years, 232 aged 30 to <45 years, 205 aged 45 to < years, and 82 aged ≥60 years. All
1 040 people tested negative for plasmodium antigen detection kit. One case of Plasmodium vivax detected by plasmodium microscopic etiology, with a detection rate of 0.10%. One case of P. vivax was also detected by fluorescent quantitative PCR and
nested PCR, with a detection rate of 0.10%. Among them, one case of P. vivax was detected in Banwai District, Mengmao
County, the Second Special Zone of Shan State, Myanmar, with a detection rate of 0.35%. The detection rates of malaria
parasites in Banlao Township in Cangyuan Va Autonomous County of Lincang City, Yunnan Province and Yongmo Township
and Dayan Township, Nandeng Special District, the Second Special Zone of Shan State, Myanmar were both 0. The difference in
the detection rate of malaria parasites among the three survey sites was not statistically significant (χ2
=2.682, P>0.05). The
asymptomatic P. vivax infection was detected in a 6-year-old girl from Banwai District, Mengmao County, the Second Special
Zone of Shan State, Myanmar. Conclusions RDT is not suitable for malaria screening in low malaria area and elimination
area. Microscopic examination and PCR can be used for malaria screening, but PCR operation is complex and costly. In
surrounding areas outside of China, malaria is still prevalent, while there is no source of malaria infection in border villages of
Cangyuan Va County. However, there is a risk of importation, and timely and effective measures should be taken to prevent reintroduction and transmission.

OBJECTIVETo investigate the expression of HERC4 in human breast cancer tissues and its relationship with the clinicopathological features.
METHODSRT-qPCR was used to detect mRNA expression of HERC4, and Western blotting and immunohistochemistry were employed to detect protein expression of HERC4 in 67 breast cancer tissues and adjacent breast tissues.
RESULTSThe results of RT-qPCR showed a significantly higher mRNA expression of HERC4 in breast cancer tissues than in the adjacent breast tissues (P<0.05). Western blotting demonstrated HERC4 over-expression in breast cancer tissues compared with the adjacent breast tissues (P<0.05). Immunohistochemistry revealed HERC4 expression located predominantly in the cell cytoplasm. Positive HERC4 expression was detected in 61.2% of the breast cancer tissues as compared to 19.4% in the adjacent breast tissues, and its expression level was closely correlated with TNM stage and the histological grade (P<0.05).
CONCLUSIONHERC4 is correlated with the tumorigenesis and progression of breast cancer and may serve as a potential biomarker for early diagnosis and also as a potential therapeutic target in breast cancer.

The heterogeneity and complexity of malaria involves political and natural environments, socioeconomic development, cross-border movement, and vector biology; factors that cannot be changed in a short time. This study aimed to assess the impact of economic growth and cross-border movement, toward elimination of malaria in Yunnan Province during its pre-elimination phase. Malaria data during 2011-2016 were extracted from 18 counties of Yunnan and from 7 villages, 11 displaced person camps of the Kachin Special Region II of Myanmar. Data of per-capita gross domestic product (GDP) were obtained from Yunnan Bureau of Statistics. Data were analyzed and mapped to determine spatiotemporal heterogeneity at county and village levels. There were a total 2,117 malaria cases with 85.2% imported cases; most imported cases came from Myanmar (78.5%). Along the demarcation line, malaria incidence rates in villages/camps in Myanmar were significantly higher than those of the neighboring villages in China. The spatial and temporal trends suggested that increasing per-capita GDP may have an indirect effect on the reduction of malaria cases when observed at macro level; however, malaria persists owing to complex, multi-faceted factors including poverty at individual level and cross-border movement of the workforce. In moving toward malaria elimination, despite economic growth, cooperative efforts with neighboring countries are critical to interrupt local transmission and prevent reintroduction of malaria via imported cases. Cross-border workers should be educated in preventive measures through effective behavior change communication, and investment is needed in active surveillance systems and novel diagnostic and treatment services during the elimination phase.

Objective To investigate the awareness of malaria-related knowledge, the use of mosquito nets and their influencing factors among residents in Banlao Township, Cangyuan County, Yunnan Province.. Methods In August 2020, 19 settlement sites in Banlao Township, Cangyuan County, Lincang City, Yunnan Province were selected as study areas, and permanent residents at ages of 10 years and older were enrolled for a questionnaire survey, including residents’ demographics, family economic status, malaria control knowledge and use of mosquito nets. In addition, the factors affecting the use of mosquito nets in the night prior to the survey were identified using multivariate logistic regression analysis. Results A total of 320 questionnaires were allocated, and all were recovered (a 100% recovery rate). There were 316 valid questionnaires, with an effective recovery rate of 98.75%. The 316 respondents included 152 men and 164 women and 250 Chinese respondents and 66 foreign respondents. The awareness of clinical syndromes of malaria was significantly higher among Chinese residents (71.60%) than among foreign residents (50.00%) (χ2 = 11.03, P < 0.01), and the proportions of Chinese and foreign residents sleeping under mosquito nets were 46.00% and 69.70% on the night prior to the survey, respectively (χ2 = 11.73, P < 0.01). Multivariate logistic regression analysis identified ethnicity group and type of residence as factors affecting the use of mosquito nets in the night prior to the survey. Conclusions The awareness of malaria control knowledge, the coverage and the use of mosquito nets were low among residents in Banlao Township, Cangyuan County, Yunnan Province. Targeted health education is recommended to improve the awareness of malaria control knowledge and self-protection ability. In addition, improving the allocation of long-lasting mosquito nets and health education pertaining to their uses and increasing the proportion of using mosquito nets correctly is needed to prevent re-establishment of imported malaria.
