Objective To explore quality of life and coping style of autistic children' s parents, and correlation between them. Methods 68 parents of children with autism and 64 healthy children' s parents were tested with comprehensive assessment questionnaire of the quality of life and coping style questionnaire. Data were analyzed by t -test and multivariate regression analysis. Results The scores of material life and mental health dimensions in study group(48.18 ± 12.80,60.63 ± 10.18 ) were lower than that in control group(52.71±9.84,65.79±8.64) and the difference was significant( t= -2.04, P＜0.05; t= -3.09, P＜0.01 ). The scores of "problem solving" coping style in study group were slower than in control group; the scores of fantasy and wincing coping style in study group were higher than that in control group. By multivariate regression analysis showed that the scores of "problem solving" coping style were positively correlated with total score of life quality,physical health,mental health and social function dimensions; the scores of "fantasy" coping style had negative correlation with the total score of life quality; the scores of "wincing" coping style had negative correlation with mental health dimension. Conclusion Parents of autistic children were more susceptible to problems of physical life and mental health. Compared to parents of normal children they are more in "fantasy and wineing style and less in" problem solving style to cope with stress, so it would affect the quality of life and mental health badly and need early intervention.

Objective To explore the influence of social support and coping style on body and mind symptoms of patients with laryngeal carcinoma. Methods SCL-90, SSRS and MCMQ were used for the questionnaire survey of 168 patients with laryngeal carcinoma. Results The result of SCL-90 showed that all items were higher than those of norm in China, except the interpersonal relationship sensitivity and psychotic symptoms. The result of SSRS showed that the total score of social support was higher than that of norm, while the availability of support was obviously lower than that of norm. The result of MCMQ showed that avoidance and submissiveness were used frequently in patients, and avoidance was negatively correlat-ed with the factors of psychology. Conclusions Before the nursing plan and health consultation are set for patients with laryngeal carcinoma, the patients' social support should be used sufficiently, and the effect of coping style on patients' mental health should be evaluated.

Objective To investigate a feasibility of treatment planning in thoracic esophageal carcinoma with 3-deoxy-3-fluorothymidine (FLT) PET-CT and to compare with fluorodeoxyglucose (FDG) PET-CT based on dosimetric analysis.MethodsTwenty-two patients with esophageal squamous cell carcinoma detected by FLT and FDG PET-CT were enrolled.The gross tumor volumes ( GTV ),clinical target volume(CTV) and planning target volume ( PTV ) were delineated using treatment planning system of Philips Pinnacle3 based on the optimal threshold of FLT and FDG PET-CT respectively,and to make two groups simulation treatment planning.The parameters of dose-volume histograms in two groups planning were compared in the similar direction and ensuring prescribed dose line surround 95% target volume.Results The values of GTV,CTV and PTV in FLT PET-CT planning were less than those of FDG,that dose received by spinal cord in two planning were not significantly yet ( t = - 1.60,- 1.55,all P ＞ 0.05 ).While,the values in mean lung dose,V5,V10,V30,V40 and V50 of bilateral lung,mean heart dose,and V30 of heart in FLT PET-CT planning were significant lower than those of FDG( t = -5.442 - -2.637,all P ＜0.05).Conclusions Compared with FDG,FLT PET-CT based treatment planning brings potential benefits for lungs and heart.

Objective To establish a optimal method and threshold of 3-deoxy-3-fluorothymidine (FLT) PET-CT in delineating the biological target length of gross tumor in esophageal carcinoma, and to compare FLT PET-CT with other imaging modalities including esophagoseopy, esophagography, CT and flu-orodeoxyglucose (FDG) PET-CT. Methods Twenty-four patients with esophageal squamous cell carcinoma treated with radical surgery were enrolled. Before surgery, all the patients underwent FLT PET-CT, esepha-goscopy and esophagography. Twenty-two patients also received FDG PET-CT scan. Gross tumor volumes (GTV) were delineated using seven different threshold of FLT PET-CT: visual interpretation, standardized uptake value (SUV) 1.3, SUV 1.4, SUV 1.5, 20% of maximum standard uptake value (SUV_(max)), 25% SUV_(max), and 30% SUV_(max). Three different thresholds of FDG PET-CT were used, including visual interpre-tation, SUV 2.5, and 40% SUV_(max). The length of tumors on FLT PET-CT scan were measured and recorded as L_(FLTvis), L_(FLT1.3), L_(FLT1.4), L_(FLT1.5), L_(FLT20%), L_(FLT25%), and L_(FLT30%), respectively. The length of tumors on FDG PET-CT scan were recorded as L_(FDGvis), L_(FDG2.5), and L_(FDG40%), respectively. The length of tumors on CT, esophagography and esophagoscopy were recorded as L_(CT), L_(X-ray) and L_(Scopy). All of these results were com-pared with the length of gross tumor in the reseeted specimen measured by pathological examination (L_(Path)), Results The L_(Path) was (4.90±2.14) cm. The Length of tumors delineated by different methods, being from short to long, were L_(FDG40%), L_(Scopy), L_(X-ray),L_(FLT1.5),L_(CT),L_(FLT30%),L_(FLTvis),L_(FLT1.4),L_(FLT25%), L_(FDG2.5),L_(FDGvis),L_(FLT1.3),L_(FLT20%). The mean values were (3.85±1.52), (4.46±2.23), (4.63± 2.37), (4.64±2.38),(4.69± 1.85),(4.75±2.19) ,(4.85±2.33),(4.87±2.35),(5.05±2.20), (5.08± 2.19) ,(5.10±2.22), (5.21±2.40) and (5.53±2.17) cm,respectively. The correlation coefficients were 0.91,0.93,0.88, 0.95, 0.90, 0.81,0.96, 0.96, 0.80, 0.99, 0.99, 0.95 and 0. 79 , respective-ly. All the P values were 0. 000. L_(FLT1.4) of FLT PET-CT and L_(FDG2.5) of FDG PET-CT were found more ap-proximate to L_(Path). There was no significant difference between L_(FLT1.4) and L_(FDG2.5) (1= 1.23, P = 0.232), and the correlation coefficient was 0.96 (P = 0. 000). Conclusions Thresholds of SUV 1.4 on FLT PET-CT and SUV 2.5 on FDG PET-CT could optimally estimate the tumor length measured by pathological examina-tion, and could be objective and simple methods for semiquantitative analysis.

OBJECTIVETo find the difference of the shapes and properties and the microscopic frameworks between wild and cultivated Radix Saposhnikovia.

METHODThe shapes and properties, the characters of transverse section, the powder and disintegrated tissue of roots of medical materials were compared by microscopic measuring.

RESULTWild Radix Saposhnikovia had a long conical or cylindrical root, and fewer root branches. It showed a close annulus grain on top root, cortical section of root in light brown colour, many brown oil spots and possessed typical odor, While cultivated Radix Saposhnikovia had many root branches, and showed less annulus grain on top root, cortical section of root in light yellow brown colour, less brown oil spots and possessed light odor. The difference of microscopic histological structure was that wild Radix Saposhnikovia had phloem transverse section of root with many rotundity oil tube lining up 10-22 rings, xylem vessel with radiate rank, and indistinct annual ring. While cultivated Radix Saposhnikovia had phloem transverse section of root with oil tube lining up 10-11 rings and xylem vessel with distinct annual ring.

CONCLUSIONThere exists several differences between wild and cultivated Radix Saposhnikovia in shapes and properties and differences of microscopic frameworks. The main characteristics are the differences of shapes and numbers of oil tube of phloem transverse section of root. The cultivated Radix Saposhnikovia of 1-4 years can be recognized by annual rings of xylem vessel.

Objective:To investigate the clinical characteristics of elderly patients with coronavirus disease 2019(COVID-19), in order to provide scientific evidence for the diagnosis and treatment of COVID-19 in elderly patients.Methods:Clinical data of 102 patients with COVID-19 admitted to the B11 East Ward of the Zhongfaxincheng campus and the E1-3 ward of the Guanggu Campus of Tongji Hospital affiliated to Huazhong University of Science and Technology in Wuhan from 1 February 2020 to 28 February 2020 were retrospectively collected and analyzed.Patients were categorized into 2 groups: the elderly group(≥60 years old)and the young and middle-aged group(<60 years old). Differences in epidemiological features, demographics, clinical symptoms, laboratory results and imaging findings between the two groups were retrospectively analyzed.Results:Among 102 patients with COVID-19, 58 were in the elderly group(≥60 years old), with a median age of 67.0(63.8, 71.0)years old, and 44 in the young and middle-aged group(<60 years old), with a median age of 47.5(38.0, 51.8)years old.There was no significant difference in gender ratio between the two groups( χ2=0.033, P=0.855). Of 102 patients, 42.0%(21/50)had close contact with an infected person, 14.0%(7/50)were from infection clusters, and 18.0%(9/50)had suspected hospital-acquired infections.Fever and cough remained the most common symptoms, but gastrointestinal symptoms such as nausea, poor appetite, diarrhea and muscle cramps were also warning signs.Fatigue and cough were the most common presenting symptoms in elderly male patients.Bilateral patchy infiltrates(57.9%, 22/38)and ground-glass opacities(42.1%, 16/38)were the main imaging features and 42.1%(16/38)patients had multiple areas of the lungs involved.Over 50% patients had increased levels of blood glucose, D-dimer, fibrinogen, C-reactive protein, procalcitonin, multiple cytokines and neutrophil-to-lymphocyte ratio, as well as decreased levels of albumin, hemoglobin, hematocrit, lymphocytes and serum calcium.Compared with the young and middle-aged group, the elderly group had higher rates of abnormality in levels of D-dimer and serum calcium( χ2=7.067 and 4.166, P=0.008 and 0.041). Conclusions:Fever and cough are the most common symptoms in elderly patients with COVID-19.Elderly patients with COVID-19 have multiple abnormalities in clinical laboratory test results, which show a certain level of specificity compared with young and middle-aged patients.

Objective To study the relationship of the large multifunctional proteasome 7 (LMP7) gene polymorphism with susceptibility to type 1 diabetes mellitus (DM-1) and the DR3 gene in south Chinese Han population.Methods LMP7 genotypes and the DR3 gene were identified in 71 DM-1 patients and 86 healthy persons (as controls) by polymerase chain reaction-restriction fragment length polymorphism. DM-1 patients and controls were divided into DR3-positive and DR3-negative subjects. The frequencies of LMP7 genotypes and alleles were compared between DM-1 patients and controls respectively in the random subjects and in the DR3-matched subjects. Furthermore, DM-1 patients were divided into 3 groups according to the age of diabetic onset: group A≤14 years, group B 15-30 years, group C≥31 years.Results In the random subjects, the frequency of LMP7-B/B was lower (39% vs 58%, P<0.05) and that of LMP7-B/A was higher (54% vs 31%, P<0.01) in DM-1 patients than that in controls. In DR3-positive subjects, the frequencies of LMP7 genotypes and alleles showed no differences between DM-1 patients and controls. In DR3-negative subjects, the frequency of LMP7-B/B was decreased (40% vs 61%) and that of LMP7-B/A was increased (55% vs 28%, P<0.01) in DM-1 patients. The frequencies of LMP7 genotypes and alleles showed no significant differences among different ages of diabetic onset.Conclusions LMP7-B/B may be the protective genotype, and LMP7-B/A may be the susceptible genotype of DM-1, and this may not be affected by the DR3 gene. Persons with LMP7-B/B may have a decreased risk, and those with LMP7-B/A have an increased risk suffering from DM-1. The LMP7 gene may not be associated with the age of diabetic onset.
