Analysis on the quality of malaria blood examination from 2012 to 2014 in Guizhou Province / 中华地方病学杂志

Objective To understand the quality of blood slide-making and the ability of films reading in Guizhou,in order to strengthen the detection ability on Plasmodium.Method The quality of blood slide-making and the medical result were assessed by re-checking all the 609 blood samples of network reported cases and a part of negative cases from 2012 to 2014 according to Technical Plan of Eliminating Malaria (2011) and Diagnostic Criteria of Malaria (WS 259-2006).Results The blood slide-making,stain,blood slice cleanliness were 48.93％ (298/609),62.56％ (381/609) and 55.50％ (338/609),respectively.The diagnostic coincidence rate was 94.91％ (578/609),and the diagnostic coincidence rate of the positive cases and the negative cases were 73.77％ (45/61) and 98.72％ (541/548).Conclusion The diagnostic coincidence rate is satisfied in Guizhou.But the microscopy quality of Malaria parasite should be improved.

Investigation on current situation of malaria blood examinations in township-level hospitals of Nantong City / 中国血吸虫病防治杂志

Objective To understand the quality of malaria blood examinations in township?level hospitals,so as to provide the evidence for continuing the malaria blood examinations in the stage of post?malaria elimination. Methods A total of 64 township hospitals were investigated and 640 negative malaria blood slides were scored individually according to 10 indicators inMalaria Elimination Technical Schemein 2013 and 2014. The single and multiple indicators were calculated,and the work of blood examinations and situation of technicians were investigated. The data of malaria blood examinations and patient discovery in township hospitals of Nantong City were collected and analyzedduring the period of 2011-2014. Results Forthe single indi?cator,29.5%of the thick blood films did not reach the standard,and 35.8%of thin blood films did not reach the standard. For the multiple indicators,blood slides with more than 4 indicators below the standard(poor quality)accounted for 32.5%. From ma?laria blood examinations and malaria situation,the number of slides was 194 635 during the period of 2011-2014,and there were no local vivax malaria casesin 4consecutive years from 2011 to 2014,andlocal malaria has been effectively controlled in Nantong City. For health facilities where malaria patients initially presented,the township and village level accounted for 16.3%,and county and higher level accounted for 83.7%. Conclusions The quality of malaria blood examinations in township level hospitals of Nantong City is not high and the microscopic examination has a relatively low efficiency in the discovery of ma?laria cases. A new model for malaria blood examinations needs to be further explored.

Experimental research ofHaizao-Xiangsheng mixture in the treatment of chronic pharyngitis / 国际中医中药杂志

ObjectiveTo observe the effect ofHaizao-Xiangsheng mixture on signs and symptoms, blood index and tissue pathology of rabbit models with chronic pharyngitis.Methods60 Japanese white rabbits by random grouping method were divided into normal control group, model group, positive control group andHaizao- Xiangsheng mixture with high, medium and low dose group, with 10 rats in each group. Except the normal control group, rabbits in other groups were performed spraying ammonia in pharyngeal portion and submucosal injection of turpentine oil preparation to create chronic pharyngitis models. TheHaizao- Xiangsheng mixture, high, medium and low dose group were treated withHaizao-Xiangsheng mixture of 42, 21, 10.5 g/kg, the positive control group was treated with watermelon frost Runhou tablet suspension 5.04 g/kg, the normal control group and model group were treated with the same volume of saline. Animal signs and symptoms were recorded daily (including general conditions and temperature). After continuous administration of 7 days, red blood cell count (RBC), white blood cell count (WBC), percentage of neutrophils (N%), the percentage of mononuclear cells (M%) and percentage of lymphocytes (L%) were detected to observe the histological change of pharyngeal mucosa and lower tissue pathology.ResultsAfter administration, compared with the model group, high dose group ofHaizao-Xiangsheng mixture rabbit body temperature dropped (38.90 ± 0.21℃ vs. 39.23 ± 0.39℃,P< 0.05), WBC (10.1 ×1012/L ± 1.73 ×1012/Lvs. 13.1 ×1012/L ± 1.69 ×1012/L) decreased, and RBC increased (5.73 ×109/L ± 0.59 ×109/Lvs.5.19 ×109/L ± 0.43 ×109/L,P<0.01).ConclusionsHaizao-Xiangsheng mixture can improve signs and symptoms, hematology indexes and histopathological changes of the experimental rabbit models of chronic pharyngitis.

Malaria surveillance in Shanghai from 2005 to 2012 / 中国血吸虫病防治杂志

Objective To understand the status of malaria prevalence in Shanghai,so as to provide the evidence for evaluat-ing and promoting malaria elimination. Methods The data of population,malaria endemic and monitoring in Shanghai from 2005 to 2012 were collected and analyzed. The malaria positive rates in febrile patients and normal population,the malaria antibody lev-els of the floating population and location pupils,and the species and density of mosquitoes were investigated and the results were analyzed. Results The blood examples from 400 177 febrile patients with 0.36%of the total population were examined for malar-ia,and the annual rates of blood examination varied from 0.15%to 0.83%in the period of 2005 to 2012. Before 2010,the annual blood examination rate was lower than 0.20%,but increased significantly since 2010 because of the implementation of the Action of Malaria Elimination in Shanghai from 2010 to 2020. Totally 604 malaria cases were found and the positive rate of blood examina-tion was 0.15%. During the period of 2006 to 2008,more than 100 malaria cases were found every year,but the number of malaria cases decreased since 2009,and only 26 cases was found in 2012. Since 2011,all the malaria cases have been found infected out of China according to the questionnaire investigation. The malaria positive rate of blood examinations decreased from 0.61% to 0.03%yearly. The proportion of local residents who had the blood examination was 79.02%,but that of the malaria positive in float-ing population was 83.44%. The active case detection was carried out in 15 759 persons and five cases were found in 2007 and 2008,respectively. The level of malaria antibody was tested in 1 239 440 floating population with the average positive rate of 0.04%. The level of malaria antibody was also tested in 7 065 local pupils but there was no positive for malaria. Only Anopheles si-nensis was found in Shanghai suburb,but no other Anopheles mosquitoes were found at the city or towns. The peak of Anopheles den- sity was from the end of July to August. Conclusions Malaria surveillance is carried out efficiently in Shanghai,and the result shows Shanghai is in the phase of malaria elimination. The more attention should be paid to persons coming from malaria endemic areas for the malaria blood examination and the general and advanced hospital should maintain the ability of malaria blood exami-nations simultaneously.

Situation of P. vivax malaria in Ahmedabad city – A study in purview of national guidelines.

Background: Malaria is still the most important cause of morbidity-mortality in India. NVBDCP in urban areas is implemented through UHCs. In Gujarat, 89764 malaria cases were reported in 2011 with 127 deaths with 17.9% of them being the P. vivax (Pv) cases. Ahmedabad is at the receiving end of malaria menace due to its rapid growth. Compared to 2011, significant rise in number of Pv cases has been observed in Ahmedabad in 2012. Aims & Objective: The study was carried out to assess the Pv malaria detection modalities, relevant indices, existing radical treatment strategies and adherence to national guidelines in the urban areas of Ahmedabad. Material and Methods: Data of all 9 UHCs of south zone, catering total population of approximately 1 million and showing significant rise in Pv cases were verified clubbed with field analysis, for the corresponding quarters of March, April and May of two consecutive years–2011-2012. Concerned healthcare staff was interviewed. Guidelines and definitions of national anti-malarial guidelines and operational manual were followed. Process indicators for surveillance, case finding and disease burden were considered. Results: Out of total blood smears examined, Pv cases raised from 97 (2011) to 382 (2012). Statistically significant rise of Pv% was 0.35% and 2.79% in active and passive slide collection respectively. 71% slides were actively collected in both years. QBER rose from 1.50% to 2.41%. QPI rose from 0.12 to 0.39. Successful RT completion decreased from 59.8% to 29.1%. Knowledge regarding national-anti-malarial-guidelines was satisfactory in more than 70% of healthcare functionaries. Conclusion: Number of cases significantly increased in two years, Pv-positivity rise being 1.04%. Active slide collection is static. Rise in Pv-positivity should trigger improvement in the same. Average QBER and QPI rose in two years. QBER never reached prescribed levels. Successful RT-completion is the key towards drug-resistance and relapse prevention. Adherence to national-anti-malarial-guideline is imperative.

Subacute Effects of Deep-Sea Water from the Japan Sea on Blood Examination Values in Mice

Objectives: To clarify the characteristics of deep-sea water (DSW), we investigated the hematological, immunological and biochemical effects of DSW, specifically the so-called Japan Sea Proper Water (JSPW), samples of which we collected from the Japan Sea at a depth of about 300 meters. Methods: Five groups of five mice each were orally administered, ad libitum for 12 weeks, one of the following: 1.2% DSW, 12% DSW, 1.2% surface-sea water (SSW), 12% SSW, or purified water (control). Results: Among these groups, no significant differences were observed in the average reduction of water intake, food consumption or body weight. The mean corpuscular volume, however, was significantly lower (p<0.05) in the 1.2% DSW group than in the control group. Moreover, serum immunoglobulin G and A values were significantly higher (p<0.05) in the 12% DSW and the 12% SSW groups, respectively, compared with the control group. In addition, the serum glucose value in the 12% DSW group was significantly higher (p<0.05) than in the control group. Conclusions: The findings of the present study suggested the presence of some toxic components in DSW. Before a final answer is reached about whether DSW, and specifically JSPW, is bad for human health, the pathophysiology of findings such as the decreased mean corpuscular volume, the higher immunoglobulin G value and the higher glucose value should be investigated.

Bone marrow and peripheral blood examination in non-Hodgkin lymphoma at initial diagnosis / 中国实用内科杂志

Objective To explore the value of bone marrow and peripheral blood examination in non-Hodgkin lymphoma(NHL) at initial diagnosis.Methods Smears of bone marrow and peripheral blood from 103 cases of NHL were stained according to Wright. Paraffin-embedded sections of bone marrow and lymphadenopathy biopsy were stained according to H-Giemsa-E. Immunotyping of NHL was performed immunohistochemically.Results Bone marrow involvement (BMI) by NHL was found in 28 (27 2%) cases.In 8 of the 28 cases without superficial lymphadenopathy,the diagnosis of NHL was established through bone marrow and peripheral blood examination.Seven of the 28 cases in stage Ⅰ?Ⅱ?Ⅲ were confirmed to be in stage Ⅳ based on bone marrow examination. Lymphoma cells in bone marrow and peripheral blood varied in morphology,they were mainly of four patterns:blast type?polymorphic lymphocyte type?small lymphocyte type?histiocyte-like lymphocyte type.Patients with BMI were more likely to have cytopenias in peripheral blood and trilineage of bone marrow depressed than those without BMI.Patients without BMI had a stimulated phenomenon in bone marrow.Conclusion Examination of bone marrow and peripheral blood is important for diagnosis and staging of NHL,especially for the diagnosis of patients without histological evidence of lymph node.
