Objective To improve the knowledge about controlling plague in cadres, masses, and the medical staff in plague affected area in Dinghian county of Shaanxi province and to assess the efforts of health education activities. Methods In 2008, the education activities carded out by the government-related departments were investigated. The awareness of plague control and assessment was obtained through a written survey, questionnaire and interviews on clinic. Results Some education activities were carried out in plague area of Dingbian county, such as training, issuing educational materials, broadcasting plague scientific educational films and arranging knowledge grand prix. The rates of knowing plague clinic, epidemiology, prevention and the "three prohibitions and three alerts to report" were as follows: the cadres were 50.50%(101/200),63.69%(414/650),78.67%(118/150), the masses were 64.71% (66/102),87.91% (269/306),76.47% (78/102) and the medical staff were 64.18% (543/846) ,68.51%(322/470),67.02%(63/94). The passing rates of the cadres, the masses and the medical staff were 70.00% (35/50),92.16% (47/51),74.47% (35/47). Conclusions Health education can strengthen health consciousness of cadres and masses and improve the ability of the medical stalf on controlling sudden epidemic situation. Reinforcing plague control knowledge and training of medical staff are still important for health education in the future.

OBJECTIVETo study the effects of rhizoma Astilbes chinensis in abirritation, blood activation, cough relieving and sputum elimination.

METHODThe antalgic function of rhizoma A. chinensis was tested by hot-plate method and writhing reaction. The acute blood-stasis model rats were made by Injection of adrenaline hydrochloride along with stimulation by ice water. The effects of cough relieving and sputum elimination were observed by the ammonia water-induced tussive mice and excretion of phenol red in the airway of mice. The maximum tolerance dose of rhizoma A. chinensis was also determined during the acute toxicity test.

RESULTThe data were analyzed for statistical significance by t-test, which shows that the decoction of rhizoma A. chinensis is significantly effective in reducing the frequency of licking behavior of mice on hot-plate and writhing response induced by acetic acid, improving the hemarheology of acute blood-stasis model rats, prolonging the latent period, reducing the frequency of cough induced byammonia, and in increasing the quantity of phenol red output from the trachea in mice. The result acute toxicity test shows that maximum tolerance dose of gastrogavage in mice was 400 g x kg(-1). Which was 666. 7 times of that clinically used for human.

CONCLUSIONRhizoma A. chinensis has the effects of abirritation, blood activation, cough relieving and sputum elimination, and is safe in clinical application.

OBJECTIVETo evaluate the role of buccal-fat-pad flap in the lined coverage of the maxillary bone graft for the maxillary reconstruction after the tumor excision.

METHODSBased on the cadaver anatomical observation of the buccal-fat-pad, 38 patients with the maxillary tumors were undertaking the treatment in this paper. Under general anesthesia, the buccal-fat-pad flap was elevated and transferred to the anterior or nasal cavities as a line of the sinus after the tumor was immediately excised through an intro-oral or external approach. The bone from the ribs was then grafted in the place for the maxillary support.

RESULTSAfter the anatomical evaluation, 38 patients were carried out the operation successfully. All of the grafted bones were well covered without bone exposure. The aesthetic appearance was achieved.

CONCLUSIONBone graft lined by the pedicled buccal fat pad flap may be a safe and good method for reconstruction of the maxilla with a lower rate of re-absorption and sequestration.

Objective To evaluate the condition of rebuilding stove for preventing coal-buming fluorosis in Ankang City of Shaanxi Province in 2006.Methods Guided by local health administration department in Shaanxi.five counties-Zhengping,Langao,Hanyin,Ziyang,Shiquan-were chosen as rebuilding stove regions in Ankang City.Fifteen housewives were chosen randomly in each village in each county,they were quizzed for the knowledge of health.Fifty students were chosen randomly in each school in each county,they were quizzed for the knowledge of health too.Data of rebuilding stove were refferred.Results Ninty-seven point two per cent(243/250)of the ovens were appropriately sealed,96.8%(242/250)were efficiently exhausted,the rate of oven correctly used was 97.2%(243/250),the awareness rates of healthful knowledge were 85.6%(214/250)in adults and 97.8%(485/496)in children.Data of rebuilding stove were documented systemically,completely and precisely.ConelusionFive model counties in Ankang City have fulfilled the demand.

OBJECT: To obtain values of normal human lung and diffuse pathological changes, in order to provide a simple and convenient diagnostic method for measuring human visceral organs in the autopsy of pathology and forensic pathology. METHODS: The exact mass, volume and density of normal and pathological lung were synchronously measured with the intelligentized volume-densimeter made by authors. RESULTS: The date-base about the volume and density of human lung with different races were established for anatomy, anthropology and biodynamics. In two cases of over-load in circulation and water toxicosis, the severe lung edema was proved with the scale of lung density, which was atypical edema in the lung tissue. CONCLUSION Measurement of visceral organs in the autopsy can assist to an integrative pathological diagnosis.

OBJECTIVE: To investigate the epidemiological characteristics, phenotype, genotype, and prognosis of medium-chain acyl-CoA dehydrogenase deficiency (MCADD) in the Chinese population. METHODS: A retrospective analysis was performed for the clinical data of the neonates who underwent screening with high-performance liquid chromatography-tandem mass spectrometry from January 2009 to June 2018 and were diagnosed with MCADD by gene detection. RESULTS: A total of 2 674 835 neonates underwent neonatal screening, among whom 12 were diagnosed with MCADD. Gene detection was performed for 10 neonates with MCADD and found 13 mutation types at 16 mutation sites of the ACADM gene, among which there were 7 reported mutations (p.T150Rfs*4, p.M1V, p.R206C, p.R294T, p.G310R, p.M328V, and p.G362E), 5 novel mutations (p.N194D, p.A324P, p.N366S, c.118+3A>G, and c.387+1del G), and 1 exon 11 deletion; p.T150Rfs*4 was the most common mutation (4/16). The detection rate of mutation sites in the ACADM gene was 80%. No phenotype-genotype correlation was observed. Dietary guidance and symptomatic treatment were given after confirmed diagnosis. No acute metabolic imbalance was observed within 4-82 months of follow-up. All neonates had good prognosis except one who had brain dysplasia. CONCLUSIONS MCADD is relatively rare in southern China, and p.T150Rfs*4 is a common mutation in the Chinese population. Cases with positive screening results should be evaluated by octanoylcarnitine C8 value and gene detection.
