Abstract: Objective To analyze the epidemiological characteristics, prevention and control strategies, measures and the effects achieved of malaria in Huangshi City from 1951 to 2021, and to offer a reference for further strengthening malaria eradication and control successes. Methods　Descriptive epidemiological methods were used to assess the prevalence, measurements, and impacts of malaria in different time periods based on data for malaria control in Huangshi City from 1951 to 2021, and we created "semi-log" line graphs and charts to display the prevalence of disease and the effort done in prior years in terms of prevention and control. Results　Between 1951 and 2021, 527 780 cases of malaria were recorded in Huangshi, with an average annual incidence rate of 40.07/10 000. The prevention and control of malaria has gone through four stages, namely, the high prevalence of malaria stage (1951-1979), the basic elimination stage (1980-1999), the consolidation stage (2000-2010), and the eradication stage (2011-2021). Different strategies and measures have been adopted in different epidemic periods. During the high epidemic period, great efforts have been made to carry out general surveys and treatments, and strengthen the management of symptomatic patients; during the eradication stage, prominent and classified prevention and control strategies were adopted. When the incidence rate dropped to below 1/10 000, the main measures adopted were malaria monitoring, including timely discovery and standardization of infectious sources, disposal of epidemic points, management of migrant population malaria and vector monitoring. Through active prevention and control, remarkable results were achieved, and the incidence rate of malaria fell to below 1/10 000 in 1989, reaching the level of "basic elimination of malaria" issued by the Ministry in 1999, and passed the provincial malaria elimination acceptance in 2015. In recent years, with the increasing labor exports and foreign exchanges, imported malaria has been on the rise. African countries are the main sources of imported malaria, and the main species is P.falciparum. Conclusions　Malaria was once one of the main infectious diseases endangering the health of people in Huangshi City. The preventive and control methods and procedures adopted in different epidemic periods are effective. Currently, we have entered the consolidation phase of malaria elimination, with the focus of work being to monitor, report, and timely and effectively respond to imported malaria cases, thus reducing the risk of local transmission.

Objective:To evaluate arthrography-assisted reduction in minimally invasive treatment of tibial plateau fractures.Methods:From January to May 2019, 9 patients with tibial plateau fracture were treated by arthrography-assisted minimally invasive surgery at Department of Orthopaedics and Traumatology, Hong-Hui Hospital. They were 6 males and 3 females with an average age of 45.5 years (from 27 to 63 years). According to the Schatzker classification, there were 6 cases of type Ⅱ, one of type Ⅲ and 2 cases of type Ⅳ. Arthrography was used to determine the lowest filling point of contrast medium after intra-articular injection and to ensure satisfactory reduction of articular surface after fracture reduction and bone grafting, followed by minimally invasive percutaneous plate implantation. Comparisons were made between preoperation and 6 months postoperation in the range of knee motion and knee scores of The Hospital for Special Surgery (HSS). Knee X-ray films were evaluated by the Rasmussen imaging system at 6 months postoperation. Collapse of articular surface was recorded pre- and post-operation as well as postoperative complications.Results:All the 9 patients were followed up for 6 to 9 months (average, 7 months). All patients achieved bony union within 12 weeks postoperation. The preoperative knee flexion (60.7°±13.1°) and HSS (51.9±5.7) were significantly improved to 122.4°±10.8° and 84.9±5.3 at 6 months postoperation ( P<0.05), but there was no significant difference between preoperation and 6 months postoperation in knee extension (4.4°±2.5° versus 4.6°±2.9°) ( P>0.05). The collapse of articular surface was improved from preoperative 9.5 mm (from 5 to 15 mm) to postoperative 1.3 mm (from 0 to 3 mm). The Rasmussen imaging scores at 6 months postoperation showed 6 excellent and 3 good. No such postoperative complications occurred as incision infection, joint stiffness, loosening or breakage of implants. Conclusion:Arthrography helps minimally invasive treatment of tibial plateau fracture because it can better display fracture collapse during operation and accurately judge indirect reduction of articular surface.

The impact of acupuncture for the pregnancy of in vitro fertilization-embryo transfer (IVF-ET) is discussed in the paper. Nowadays there are various conclusions about the impact of acupuncture for IVF-ET, and it may result from the differences in research designs. The effect is closely related to the demographic and clinical characteristics of subjects, such as age, the diagnosis of barrenness, blood flow index of uterine spiral arteries, the cycle of IVF, etc. Besides, the efficacy is influenced by treatment based on syndrome differentiation or not, the frequency and course of acupuncture in both the treating group and the control group, etc. If more reasonable design is achieved in the further study based on them, more reliable evidence will be provided for the effect and mechanism of the pregnancy of IVF-EF by acupuncture.

Objective To investigate the prevalence and progression process of atopic diseases in adolescents, and to assess their relationship with filaggrin(FLG)mutations. Methods Totally, 334 adolescents aged from 11 to 19 years in a middle school in shanghai were enrolled into this study. A clinical interview was carried out to determine the prevalence of atopic diseases (such as ichthyosis, atopic dermatitis (AD), asthma, rhinitis, etc)in these subjects. Peripheral blood samples were collected from 285 out of the 334 adolescents for screening for common FLG mutations, including 3321delA and K4671X. Five years later, these adolescents were followed up for reevaluation of clinical presentations of atopic diseases. Statistical analysis was carried out by the chi-square test with the SPSS 20.0 software. Results As the baseline survey showed, 19 (5.69%)of the 334 adolescents had AD, 14 (4.19%)had ichthyosis vulgaris, 36(10.78%)had allergic rhinitis, and 4(1.20%)had asthma. FLG mutations were observed in 24(8.42%) of the 285 adolescents. Five years later, 265 adoscents completed the follow-up, and 69 (20.66%)were lost to follow-up. Of the 265 adolescents reevaluated, 13(4.89%)had AD, 15(5.64%)had ichthyosis vulgaris, 27(10.15%)had allergic rhinitis, and 1 (0.38%)had asthma. By the time the second survey was performed, 6 out of the 19 patients initially diagnosed with AD had achieved complete regression, 13 had experienced a marked decrease in SCORing atopic dermatitis (SCORAD)score, and symptoms had disappeared in 9 of the 36 patients initially diagnosed with allergic rhinitis. The frequency of FLG mutations was 10.0%in patients with AD, 55.6%in those with ichthyosis, and 40.0%in those with both AD and ichthyosis, and the development of ichthyosis was associated with FLG mutations(P<0.001). Conclusions The frequency of common FLG mutations was 8.42%in these adolescents. FLG gene may be a semidominant gene associated with ichthyosis vulgaris, and multiple factors influence its expression.

Objective To study the influence of different microembolism on left ventricular systolic synchronism in pigs by detecting the real-time dypyridamole stress contrast echocardiography (RT-MCE).Methods Eighteen miniature pigs were randomly divided into three groups and underwent microembolization injection procedure through the middle of anterior descending coronary artery with different numbers of microsphere injection,as:group A(dosage 50 thousands,3 pigs),group B (dosage 120 thousands,8 pigs) and group C (dosage 150 thousands,7 pigs).The peak values and the time-to-peak circumferential strain(Circ.Strain),radial velocity (Radial Vel.) and radial strain (Radial Strain) were obtained both at mitral valve level and papillary muscle level at left ventricle short axis views using two-dimensional speckle tracking imaging(STI)analyzed by Philips Q-Lab 8.1 workshop,respectively.Results No significant difference in the presence of contraction synchrony was observed using RT-MCE.The time-to-peak Circ.Strain of microembolism related segments were prolonged at 1 week after microembolism detecting with dypyridamole stress RT-MCE (P＜0.05,both intro-group and inter-group).While time-to-peak radial strain were extended since 6 hours after the intervention to 1 week after the procedure.Conclusions Dypyridamole stress RT-MCE can be used to measure the myocardial perfusion accurately.The elongation of time-to-peak circ.strain and radial strain were developed with time in microembolism related segments.

Objective To evaluate the clinical application of our self-designed ultradistal locking tool in the intramedullary nailing for tibial fractures.Methods From January 2014 to May 2016,175 patients with tibial fracture were treated at our department.They were 119 men and 56 women,from 19 to 73 years of age (average,46.3 years).They were divided into 2 groups according to the different targeting devices used in the intramedullary nailing.Conventional locking tools were used in the 83 patients from January 2014 to January 2015 and our self-designed new ultradistal locking tools in the 92 patients from February 2015 to May 2016.The 2 groups were compared in terms of operation time,frequency of intraoperative fluoroscopy,and successful rate of one-time locking.Results There were no significant differences between the 2 groups in general clinical data(P ＞ 0.05),showing similarities of the 2 groups.The operation time(59.8 ±4.3 min),frequency of intraoperative fluoroscopy(11.0 ± 2.1 times),and rate of one-time successful locking[94.4％ (238/252)] in the ultradistal locking group were significantly better than those in the conventional locking group [73.6 ± 5.3 min,23.0 ± 3.8 times and 85.7％ (180/210),respectively] (P ＜ 0.05).Conclusions Our new ultradistal locking tools are superior to the conventional ones in that they lead to shorter operation time,less intraoperative fluoroscopy and higher successful rate of one-time locking.Additionally,the new locking tools are easy to handle and incur no extra costs.

Saliva and blood were collected from two patients who had not received post exposure prophylaxis in the cities of Wenzhou and Xinning respectively. Both patients were confirmed as positive for rabies by detection of rabies virus specific nucleoprotein antibodies in the sera by Western Blot. However, rabies virus specific RNA was only identified in the saliva collected from the patient in Wenzhou. Furthermore, the isolate Zhejiang Wz0 (H) was obtained by inoculating one-day-old suckling mice. Both nucleoprotein (N) and glycoprotein (G) genes from the isolate were amplified by RT-PCR and sequenced. Phylogenetic analysis indicated that the isolate belonged to classic rabies virus, and shared a higher homology with the street viruses from dogs in the main endemic areas in China and the street virus from dogs in Indonesia than with other known strains. Further comparison of the deduced amino acid sequences between the isolate and the vaccine strains used in China showed that the virus had a higher level of homology with the vaccine strain CTN than with the other vaccine strains (3aG, PV, PM and ERA). In particular, amino acid residues substitutions located in antigenic site Ⅲ in the G protein, which could react with the neutralizing antibodies, were observed. These results suggested that the virus belonged to the classic rabies virus, and both N and G genes diverged from the current vaccine strains used in China at either the nucleotide or the amino acid level.

Abstract As dietary issues of children and adolescents become increasingly complex, the assessment of food literacy (FL) is increasingly importance. FL involves a comprehensive cognition and practical ability concerning food among children, playing a key role in fostering healthy eating habits and improving health levels. The article explores the definition and connotations of FL, and introduces eight FL assessment tools in terms of theoretical foundations, dimensions, assessment methods, and their reliability and validity. Moreover, it provides a comparative analysis of these tools by examining their dimensional design, evaluation indicators, strengths, and weaknesses, as well as their applicable subjects and scenarios, aiming to offer references for implementing relevant policies and developing more comprehensive and effective FL assessment tools.
