To determine the distribution and drug resistance tendency of Gram-negative bacillus so as to provide a reasonable selection for antibiotic in clinical treatment.The clinical isolates bacillus were mainly Gram-Negative bacillus during three years.The detection out ratio for Gram-Negative bacillus had decreased gradually but the ratio for non-fermental gram-negative bacillus had increased.The combinations of antibiotic and enzyme inhibitor has more antibacterial activity to non-fermental gram-negative bacillus than antibiotic.The detection out ratio for ESBLs had gradually increased.

With the rapid economic growth and social development in the BRICS countries, the role of devel-opment assistance for health is becoming more and more significant. This paper describes the scales, recipient coun-tries, mechanisms and characteristics and management systems of development assistance for health in BRICS coun-tries. The paper suggests that a) it is necessary to set up a centralized international aid management agency;b) the mode of development assistance for health must be optimized;c) the scale of development assistance for health shall be increased ( over time);d) each BRIC country should use its own comparative advantages and development experi-ence to carry out development assistance for health while strengthening the cooperative power among the BRICS coun-tries;e) development assistance for health data should be more transparent and open;f) the evaluation of develop-ment assistance for health must be established and perfected.

Since the establishment of the People’s Republic of China, the development of China’s official de-velopment assistance for health has been going through three phases. To date, it has developed in many forms, inclu-ding the dispatch of medical team and the construction of health facilities. Since the market reforms, the global con-text together with the domestic socioeconomic foundations have changed; the impact of China’s relatively simple and segmented development assistance for health on the development of health systems in developing countries is limited;the effectiveness of assistance has been watered-down due to segmentation and vague management and accountability systems, as well as the lack of an overarching strategy;China’s health institutions, techniques and products suffer va-rious obstacles in their transfer to other countries where rules are dominated by western countries;compared with the increasing and multiple demands of development assistance for health from developing countries, the capacities of co-operation need to be further developed. As the paper suggests, use the “new major-country” and “new morality-in-terest” and“human oriented” concepts, as well as the ideology of“aid in order to develop, develop in order to coop-erate, so as to develop hand-in-hand” to guide China’s development assistance for health;innovate stereo-aid models to adapt to the changed foreign and domestic socioeconomic context; reform the development assistance for health management system and define rights and obligations appropriately;strengthen coordination and information sharing;link development assistance for health with global health governance to promote a maximized spillover effect;mobilize the civil society with strengthened guidance and supervision.

Abstract: Objective　To analyze the laboratory microscopic re-examination results of malaria cases in Nantong of the National Notifiable Disease Report System from 2014 to 2021 by Nantong Malaria Diagnostic Reference Laboratory, so as to evaluate the malaria diagnosis ability of Nantong Malaria Diagnostic Reference Laboratory. Methods　The blood smear and blood samples of malaria cases in Nantong from 2014 to 2021 of the National Notifiable Disease Report System were collected. Nantong Malaria Diagnostic Reference Laboratory and Jiangsu Institute of Parasitic Diseases carried out the re-examination of municipal and provincial laboratories, taking the results of provincial laboratory as the standard to compare and analyze the re-examination results of Nantong Malaria Diagnostic Reference Laboratory. Results　From 2014 to 2021, the two-level laboratories in Nantong city and Jiangsu Province re-examined the blood samples of 297 malaria cases. The microscopic examination and PCR re-examination results at the provincial level were the same：292 positive cases and 5 negative cases. The qualitative coincidence rate between Nantong microscopic re-examination results and the provincial re-examination results was 100% (297/297), without misjudgment and omission. The coincidence rate of Plasmodium typing was 96.23% (281/292). The coincidence rate of P. falciparum, P. vivax, P. ovale and P. malaria were 99.57% (234/235), 62.50% (5/8), 89.47% (34/38) and 72.73% (8/11) respectively. The consistency test results showed that the Kappa value of Plasmodium typing results between municipal and provincial laboratories was 0.89. The Kappa values of P. falciparum, P. vivax， P. ovale and P. malaria were 0.98, 0.58, 0.87 and 0.79 respectively. Conclusion　The malaria diagnosis ability of Nantong Malaria Diagnostic Reference Laboratory is generally good, and it is necessary to improve the ability of Plasmodium typing.

Objective To evaluate the effect of health education on the target population of iodine deficiency disorders (IDD) in Linxia Hui autonomous prefecture.Methods During 2006-2010,IDD health education was carried out in the target population of Linxia Hui autonomous prefecture,and IDD knowledge of 5th grade pupil and 20-50 years old child-bearing women were surveyed by stratified sampling and questionnaire survey methods to evaluate the effect of health education.Results After health education,IDD knowledge passing rate rose from 55.6％ (548/986) and 18.0％(118/657) to 90.0％(1103/1225) and 86.2％(687/797) among pupils and women,respectively.The awareness rates of iodine deficiency in causing goiter,mental retardation and birth born silly children,and the key role of iodized salt in controling IDD were increased from 79.2％ (781/986),76.5％ (754/986),51.7％ (510/986) and 82.3％ (811/986) to 88.8％ (1088/1225),85.6％ (1049/1225),68.7％ (842/1225) and 90.0％ (1103/1225) among pupils,and from 48.6％ (319/657),28.3％ (186/657),15.4％ (101/657) and 39.6％ (260/657) to 86.2％ (687/797),70.0％ (558/797),46.3％ (369/797) and 87.3％ (696/797) among women,and all the difference were significant,respectively.Belief rate held by students that health education can prevent iodine deficiency disorders was 87.3％ (1069/1225),and 52.9％ (648/1225) of the students told their parents about IDD.The rate of consciously purchase of qualified iodized salt was 87.1％ (694/797) after health education among women of childbearing age,and the consumption rate of iodized salt was 64.6％(515/797).More than 90％ of the people in relevant departments knew iodine deficiency disorders related knowledge,in particular,had a clear understanding of intellectual hazards caused by iodine deficiency,and actively supported and participated in health education in the prevention and control of iodine deficiency disorders.Conclusions Comprehensive health education measures taken through schools and religious organizations has promoted a shift in the behavior,beliefs and attitudes of its consciously purchase and consumption of iodized salt,and integrated knowledge,attitude and practice (KAP).It is a good model of health education through religious organizations in ethnic minority areas.It has promoted the health education feasibility and accessibility,and the effect is more durable.

Objective To master the status in control of iodine deficiency disorders (IDD) in Gansu province and to provide the basis for development of control strategies. Methods One county which reached the national standardization of IDD elimination was selected randomly from each of 14 cities of Gansu province in 2009, then one town was selected respectively from five directions (east, south, west, north, and central) of the above selected counties. One village was chosen from every town which was selected for investigating household iodized salt and iodized salt sales network. At the same time the thyroid of children was examined, their urinary iodine (UI) was determined, the intelligence quotient(IQ) values of children were measured and health education was surveyed in one primary school which was chosen in each of the selected town. Results A total of 1420 edible salt samples were tested;the weighted iodized salt coverage rate and the weighted qualified iodized salt rate were 99.53% and 98.15 respectively. Urine samples were collected from 1761 children included in the study. The urinary iodine median was 225.87 μg/L. The urinary iodine medians were at optimal levels in five counties, over the optimal levels in seven counties and at excessive levels in two counties. A total of 3051 children aged 8 - 10 were randomly selected for thyroid examination. The weighted thyroid goiter rate(TGR) of children was 1.9%, and TGR was higher than 5% only in Hoaggu county. IQ of 2815 children was tested and the mean IQ was 105.3, except for the country of Zhuoni and Kangle, the mean IQ of other counties were over 100. The average score of health education was 3.2.Children of 57.08% (1229/2153) knew that iodine deficiency could lead to mental retardation, 71.76% (1544/2153) knew that iodine deficiency could cause thyroid goiter, 68.04%( 1465/2153 ) knew that eating iodized salt was the best method for IDD prevention and control and 61.82%(1331/2153) informed their families of the benefits of eating iodized salt. Each town had one agency selling iodized salt and each village had one more retail store with iodized salt, but 73.5%(75/102) of the stores without license for the sales. Conclusions Great progress has been made on the prevention and control of IDD in Gansu province. The qualified iodized salt consumption rate has reached the national standard for IDD elimination, TGR has decreased markedly, the urinary iodine levels in more counties are over the optimal levels and iodized salt distribution network is basically sound. But progress in health education is uneven.

OBJECTIVETo explore the molecular mechanism and prevention of retinoic acid syndrome (RAS).

METHODSSDF-1 alpha mRNA from healthy adult lung tissue was measured by RT-PCR, CXCR4 protein expression on the cell membrane of APL cells induced by ATRA (APL-ATRA) was tested by FCM, and the rotary cell culture system (RCCS) was used to build a modal for in vitro stimulation of APL-ATRA infiltrating human lung tissue. The ability of APL-ATRA in adhesion, migration and infiltration was observed by interference from DEX, Ara-C and DNR.

RESULTSThe APL-ATRA cells could evidently infiltrate into normal lung tissue. Mean fluorescence intensity (MFI) of CXCR4 on the cell membrane of APL-ATRA cells was 30.6 +/- 1.8, which was much higher than that on unspecialized APL cells (9.8 +/- 4.2). SDF-1 alpha mRNA expression was detected positive in all 6 lung tissue. Contrary to the control groups, DEX could dramatically restrain the ability of APL-ATRA cells in adhesion and migration [(27.2 +/- 2.6)% vs. (46.0 +/- 3.0)%, (28.1 +/- 4.0)% vs. (48.2 +/- 3.0)%], while Ara-C and DNR could distinctly depress the ability in adhesion, migration and infiltration [(28.1 +/- 3.0)%, (30.2 +/- 3.2)% vs. (46.0 +/- 3.0)%; (29.0 +/- 4.0)%, (23.0 +/- 5.2)% vs. (48.2 +/- 3.0)%; (16.8 +/- 7.6)%, (17.1 +/- 6.0)% vs. (43.6 +/- 5.0)%].

CONCLUSIONIn vitro APL-ATRA cells can infiltrate into the human lung tissue. High expression of CXCR4 on APL-ATRA and SDF-1 alpha in the lung tissue may be one of the molecular mechanisms of the lung infiltration and RAS. DEX, Ara-C and DNR can dramatically restrain the ability of APL-ATRA cells in adhesion, migration and infiltration.

White coloration of the muscle of the giant river prawn (Macrobrachium rosenbergii) is a serious problem in China. The Macrobrachium rosenbergii Nodavirus (MrNV) has been confirmed to be the pathogen that causes this disorder. To develop a rapid, sensitive and specific technology for the detection of Macrobrachium rosenbergii Nodavirus isolated from China (MrNV-China), a reverse-transcription loop- mediated isothermal amplification assay combined with a lateral flow dipstick (RT-LAMP-LFD) assay method is described. A set of four primers and a labeled probe were designed specifically to recognize six distinct regions of the MrNV RNA2 gene. Results showed the sensitivity of the RT-LAMP-LFD assay was ten-times higher than the reverse-transcription loop-mediated isothermal amplification assay (RT-LAMP) with agarose gel electrophoresis. The assay was conducted with one-step amplification at 61°C in a single tube within 45 min. No product was generated from shrimps infected with other viruses, including DNA viruses (infectious hypodermal and hematopoietic necrosis virus (IHHNV); white spot syndrome virus (WSSV)) and RNA viruses (Taura syndrome virus (TSV); infectious myonecrosis virus (IMNV); yellow head virus (YHV)). Results were visualized by the LFD method. Therefore, the described rapid and sensitive assay is potentially useful for MrNV detection.

OBJECTIVETo study the epidemiological and clinical features of the mycoplasma pneumoniae pneumonia (MPP) that occurred in a single class of a kindergarten in Beijing in July 2006.

METHODSThe environment and the attendance record of the kindergarten from the beginning of August 2005 to the end of July 2006 were investigated, and the sick status of the children absent for illness were interviewed by face to face or telephone through their parents. The disease data of the in-patient children with MPP were collected through questionnaires and analyzed. Serological screening for MP was performed with the Serodia Myco II gelatin particle agglutination test (Fujirebio, Japan).

RESULTSIn mid-July 2006, in a day-care kindergarten with 3 grade classes, 3 out of 25 six-year-old children in the top class were hospitalized within 4 days and diagnosed as MPP. A total of 8 children had the symptoms of fever and cough during late May and mid-July in 2006, 5 children conduct chest radiographs and all had pneumonia, all these five children showed antibody positive for MP, 3 of them showed a more than 4-fold increase in antibody titer to MP in serum. There were no pneumoniae cases in the other two classes during the same period, and no pneumoniae cases happened among the teachers in the top class and the parents of the 5 pneumoniae children. All the children were moved to this classroom temporarily with limited ventilation and sunshine in March 2006. After improvement of the ventilation in the classroom, no additional pneumoniae cases occurred in the top class till the early September 2006. The 5 MPP children showed neither sneeze and nasal obstruction, nor skin rash, earache and any other extrapulmonary complication, and their peripheral white blood cell count was in the normal range (3.9 - 7.7) x 10(9).

CONCLUSIONThe MPP outbreak in a kindergarten was caused by poor ventilation of the temporary classroom. MP infection in children is liable to cause pneumonia.
