Objective To improve the identification of rush pneumoconiosis.Methods To analyze 47 cases of rush pneumoconiosis treated in our hospital from 2003 May to 2008 December.Results The male occupied 74% of 47 patients.The average age of onset was 34.2 ranging from 26.1 to 42.3.78.7% patiets presented with cough,sputum production,chest pain and dyspnea.4.2% patiets had PaO2 45 mmHg.85.1% patients' chest X-ray and CT images showed nodule shadows,interstitial fibrosis and ground glass attenuation.42.6% patients had restrictive ventilation disorders,2.1% obstrutive ventilation disorders 4.2% mixed ventilation disorders,and 74.5% decreased diffusing capacities.Through fiberoptic bronchoscopy,carbon sediment were seen on the 10% patients' bronchial walls,and bronchial lumen were distorted and stiff.Chronic inflammaion increased,macrophages and fibre tissues,and 21.2% dust cells were seen in pathology.All patients were treated according to their clinic symptoms.Conclusion Rush-mat dust was the main cause of rush pneumoconiosis,there were no special ways to cure this disease,prevention was the key to eliminate rush pneumoconiosis.

Objective To analyze the epidemiologic feature of overseas imported malaria in order to provide the evidence for improving the surveillance and control of malaria in Wuhan City. Methods The epidemiological investigation data of overseas imported malaria cases were collected and analyzed with an epidemiological method including plasmodium species epidemic fo?cus distribution domestic distribution population characteristics attack?diagnosis interval clinical grading etc. in Wuhan City from 2008 to 2013. Results A total of 240 overseas imported malaria cases were reported including 180 cases from Afri?can countries and the proportion of Plasmodium falciparum infections was 82.22% and 60 cases from Southeast Asian coun?tries and the proportion of Plasmodium vivax infections was 76.67% and the proportions of the parasite species were significant?ly different between the two regions χ2=105.53 P 0.001 . The male and young adults were dominant. there were no statisti?cal significance between clinical grading and attack?diagnosis interval Z=-0.99 P = 0.32 vocational background χ2=10.61 P=0.10 then clinical symptoms aggravated the situation was occurred more easily among the first attack cases χ2=7.66 P 0.05 and the falciparum malaria cases χ2=24.27 P 0.001 . Conclusions The overseas imported malaria cases are increasing rapidly with years and the malignant malaria cases were more than other malaria cases in Wuhan City. Therefore the surveillance and management of the returnees from malaria endemic areas should be strengthened continually.

Objective:To retrospectively analyze the survival outcomes of the surgical management of primary small cell carcino-ma of the esophagus. Methods:The medical records were reviewed for patients diagnosed with esophageal carcinoma and underwent esophagectomy from January 2000 to December 2009 at the Department of Thoracic Surgery of the Henan Cancer Hospital. We fo-cused on the clinical data of patients with small cell carcinoma of the esophagus. The Kaplan-Meier approach with log-rank test was used for survival analysis. Results:A total of 5,062 patients underwent esophagectomy with curative intent at the Department of Thorac-ic Surgery of the Henan Cancer Hospital;among which, 57 (1.1%) were diagnosed with small cell carcinoma of esophagus. The most common surgical approach was trans-left thoracic incision esophagectomy. Cervical esophagogastrostomy was performed for all pa-tients. The most common chemotherapy regimen was EP. The overall 5-year survival rate was 12.5%, and the median survival time was 45 months. Among the various stages, the 5-year survival rate and survival time were 25% and 50 months for Stage I, 5.9% and 43 months for Stage II, and 4.3%and 43 months for StageⅢ. Subgroup analysis showed that cases treated with surgery alone had poorer overall median survival time compared with those cases that underwent surgery plus chemotherapy (23.2 months vs. 60.7 months, re-spectively;P<0.01). Even for Stage I patients, thesurgery plus chemotherapysubgroup was associated with a significantly longer me-dian survival time than the surgery alone subgroup (81.9 months vs. 22.3 months, P<0.01). Conclusion:For patients with primary small cell carcinoma of the esophagus, surgery alone cannot provide the optimal prognosis. Surgery combined with systemic chemother-apy can improve the survival time.

Objective To explore the changes and significance of serum tumor necrosis factor-?(TNF-?),interleukin-1?(IL-1?),IL-6 and IL-10 in rats with acute necrotizing pancreatitis(ANP).Methods Sixty-four Wistar rats were randomly divided into 2 groups: sham operation group(SO group n=32) and ANP group(n=32).The ANP model was established by using retrograde injection of Sodium Taurocholate into cholangiopancreatic duct.The changes of serum endotoxin(ET),TNF-?,IL-1?,IL-6 and IL-10 in different groups and different time points were observed.Results The levels of serum ET,TNF-?,IL-1?,IL-6 and IL-10(except IL10 of ANP group in 16h) in rats of ANP group were significantly higher than those of SO group(P

Objective Evaluating the main risk factors of thyroid cancer systematicaly,to provide reference for the further development of thyroid cancer prevention strategies.Methods Such databases as PubMed,Cochrane Library,CBM,CNKI,VIP and WanFang were searched from the date of their establishment to June 10 2016 to collect the case-control studies on thyroid cancer.After study selection,assessment and data extraction was conducted by two reviewers independently,meta-analysis was performed by using the RevMan 5.1 software.Results Nineteen studies involving 4 813 thyroid cancer patients and 6 068 comparions were selected.The results of metaanalysis showed that:the risk factors of thyroid cancer mainly included history of benign thyroid disease [odds ratio (OR) =7.31,95％ confidence interval (95％CI,4.37,12.23)],family history of thyroid cancer [OR =5.13,95％CI (3.20,8.23)],high iodine diet [(marine animal food,OR =4.15,95％CI (2.47,6.99)],CT inspection history [OR =3.99,95％CI (2.10,7.60)],Negative emotions [sulking,OR =3.31,95％CI (2.23,4.91)],BMI greater than 25 [OR =2.62,95％CI (1.73,3.97)],high pressure and anxious [OR =2.60,95％CI (1.61,4.21)],getting along with people not harmoniously [OR =2.46,95％CI (1.59,3.81)],the number of pregnancies of women more than three times [OR =2.03,95％CI (1.50,2.76)],age of menarche less than 13,14 years old [OR =1.59,95％CI (1.06,2.37)].Conclusions Thyroid benign disease history,family history of thyroid cancer,high iodine diet,CT examination,BMI greater than 25,bad mood,social interaction,number of pregnancies and other factors are the independent risk factors for thyroid cancer.Corresponding prevention and control measures should be taken according to these risk factors.

Objective:To understand the applicability of different thyroid volume correction methods for school-age children in Wuhan, and to explore the appropriate thyroid volume correction methods for school-age children in Wuhan.Methods:From May to August 2019, Hongshan, Hanyang, Hannan, Jiangxia and Dongxihu districts of Wuhan were divided into five sampling areas according to five directions: east, west, south, north and middle. One primary school was selected from each area, and 40 non-boarding students aged 8 - 10 years old (gender balanced) were selected from each primary school as survey subjects. Random urine sample and household edible salt sample were collected to detect urinary iodine and salt iodine contents, and the height, weight and thyroid volume of the children were measured. At the same time, the thyroid volume was corrected by height corrected volume index 1 (HVI1), weight and height corrected volume index (WHVI), body mass index corrected volume (BMIV), body surface area corrected volume (BSAV) and height corrected volume index 2 (HVI2).Results:A total of 1 000 children aged 8- 10 years old were investigated, including 499 boys and 501 girls; among them, there were 269, 321 and 410 children aged 8, 9 and 10 years old, respectively. The median urinary iodine was 247.50 μg/L; the median salt iodine was 23.20 mg/kg; the height, weight and thyroid volume were 140.00 (133.00, 146.00) cm, 31.00 (27.00, 37.00) kg and 2.56 (2.13, 3.21) ml, respectively. A total of 30 children with goiter were detected, and the goiter rate was 3% (30/1 000). The thyroid volumes of boys and girls were 2.57 (2.16, 3.28) and 2.56 (2.10, 3.16) ml, respectively, and the difference was not statistically significant ( U = - 0.981, P > 0.05). The thyroid volumes of children aged 8, 9 and 10 years old were 2.31 (1.98, 2.81), 2.68 (2.13, 3.30) and 2.74 (2.28, 3.35) ml, respectively, and the differences were statistically significant ( H = 47.585, P < 0.01). Spearman correlation analysis showed that the original thyroid volume was positively correlated with height and weight in children aged 8, 9 and 10 years old ( P < 0.01). After HVI1 correction, no correlation was found between thyroid volume and height in children aged 8 years old ( P > 0.05), but thyroid volume was positively correlated with weight ( P < 0.01); thyroid volume was positively correlated with height and weight in children aged 9 and 10 years old ( P < 0.01). After WHVI correction, the thyroid volumes of children aged 8, 9, and 10 years old were negatively correlated with height and weight ( P < 0.01). After BMIV correction, the thyroid volume was positively correlated with height in children aged 8, 9, and 10 years old ( P < 0.01); thyroid volume was negatively correlated with weight in children aged 10 years old ( P < 0.05). After BSAV correction, thyroid volume was positively correlated with weight in children aged 9 years old ( P < 0.05). After HVI2 correction, thyroid volume was positively correlated with weight in children aged 9 years old ( P < 0.01). The thyroid volume obtained by the 5 correction methods were all smaller than the original thyroid volume, and the thyroid volume after BSAV correction was the closest to the original thyroid volume, with a difference of 0.87% - 13.87%. Conclusions:The thyroid volume of school-age children in Wuhan is affected by age, height, and weight, judgment of goiter should be corrected for these factors. BSAV is relatively independent and stable, it can eliminate the effect of height and weight on thyroid volume. It is initially considered that BSAV is suitable for the correction of thyroid volume in school-age children in Wuhan.

This study described the radiological features on echocardiography and MRI specific to cardiac amyloidosis confirmed on biopsy. Eleven cases of biopsy-proven cardiac amyloidosis were retrospectively reviewed in this study. All patients underwent biopsy, cardiac MRI and echocardiography. The main echocardiography and MRI findings were as follows: diffuse ventricular and septum wall thickening, atrial enlargement, pericardial effusion, restricted left ventricular (LV) systolic and diastolic function, characteristic granular sparkling of myocardium. MRI revealed a characteristic pattern of global subendocardial late enhancement, extending in varying degrees into the neighboring myocardium. The findings agreed with the infiltration distribution of amyloid protein. Typical abnormalities seen on echocardiography and MRI should have important diagnostic and prognostic value of cardiac amyloidosis. MRI should be considered in the diagnosis of cardiac amyloidosis if echocardiographic features are suspicious.
