ObjectiveTo evaluate the effectiveness of Gandou decoction （GDD） by analyzing theclinical efficacy of GDD combined with speech training on the treatment of dysarthria with endoretention of damp-heat in Wilson's disease （WD）， so as to provide more clinical data and theoretical support for the selection of appropriate treatment schemes for WD patients with dysarthria with endoretention of damp-heat. MethodA total of 60 eligible WD patients with dysarthria with endoretention of damp-heat were selected and divided into a control group and a treatment group according to the random grouping method， with 30 cases in each group. The control group was treated with speech training + sodium dimercaptopropanesulfonate （DMPS）， and the treatment group was combined with GDD on the basis of the control group， with eight days as a course of treatment for 32 days. The total clinical effectiveness rate （Goldstein clinical classification）， dysarthria grading assessment from China Rehabilitation Research Center， TCM syndrome scores， 24-hour urine copper content， and modified Frenchay dysarthria rating scale scores of the two groups were compared before and after treatment. ResultAfter treatment， the total effective rate of the observation group was 90.0% （27/30）， and that of the control group was 70.0% （21/30）. The total effective rate of the observation group was significantly higher than that of the control group （Z=-1.986，P<0.05）. After treatment， the modified Frenchay dysarthria score， dysarthria grading assessment from China Rehabilitation Research Center， and 24-h urine copper in the two groups were significantly increased （P<0.05， P<0.01）， and the TCM syndrome score was significantly decreased （P<0.01）. Compared with the control group after treatment， except for the respiratory and jaw score， the modified Frenchay dysarthria score of the observation group was significantly increased （P<0.05， P<0.01）. The dysarthria grading from China Rehabilitation Research Center and 24-h urine copper content were significantly increased （P<0.01）， and the observation group had better efficacy. During the study period， there were no serious adverse reactions such as fever， rash， oral and eyelid mucosal swelling， exfoliative dermatitis， vomiting， diarrhea， or allergic shock during copper excretion treatment of DPMS and oral administration of GDD. ConclusionGDD combined with speech training can improve the symptoms and efficacy of WD patients with dysarthria with endoretention of damp-heat and enhance the patients' living standard to a certain extent， which can be widely used in clinics.

Background and objective Lung cancer is the malignant tumor with the highest incidence rate and the heaviest disease burden in China.In recent years,lung cancer has shown a high incidence trend,seriously affecting the health of the population.In this paper,we analyze the characteristics of lung cancer incidence in 2019 and the trend of incidence rate from 2010-2019 in the tumor registration area of Gansu province,in order to provide a reference basis for the development of lung cancer prevention and control strategies in Gansu province.Methods By analyzing the cases of lung cancer incidence in the tumor registration area of Gansu province in 2019,we calculated the incidence rate,medium incidence rate,world in-cidence rate and other related indexes;we used Joinpoint to calculate the annual percentage change(APC)for trend analysis.Results In 2019,a total of 3757 new cases of lung cancer were reported in Gansu province,accounting for 14.96%of all new malignant tumors.The incidence rate,medium incidence rate and world incidence rate and world rate of lung cancer were 40.52/105,25.78/105,25.86/105;and the cumulative rate of 0-74 years old,and the truncation rate of 35-64 years old were 3.23%,40.03/105,respectively.The incidence of lung cancer rises with age,and is high in the age group of 40 years and above,and the incidence peaks in the male and female populations in the group of 75 years and above,and the group of 80 years and above,respectively.The crude incidence rate of lung cancer in the tumor registration area of Gansu province from 2010-2019 showed an overall increasing trend,and the rate of increase was relatively fast,with an APC 5.39%(P<0.05);Separately,accord-ing to gender,urban and rural areas,the incidence of lung cancer in all populations showed an increasing trend,and the APC of male,female,urban and rural populations were 4.98%,6.39%,6.26%,and 4.64%,respectively(all P<0.05).According to the trend analysis of lung cancer incidence rate by age group,only lung cancer incidence in the age group of 65 years and above increased at an annual average rate of 4.15%(P<0.05).Conclusion The incidence rate of lung cancer in the tumor registration area of Gansu province from 2010 to 2019 shows a rising trend year by year,and there are differences in the incidence of lung cancer in people of different genders,regions and age groups,so comprehensive prevention and control work should be carried out for the key populations of lung cancer incidence.

Objective:To describe the baseline characteristics of the subjects enrolled in the China Quantitative CT (QCT) big data program in 2018—2019.Methods:Based on baseline data from the Chinese health big data project from January 2018 to December 2019 from the eligible enrolled population, measurements of bone mineral density (BMD) and visceral adipose tissue (VAT) were performed using Mindways′ QCT Pro Model 4 system. The baseline data of age, gender, regional distribution, height, weight, abdominal circumference, blood pressure, blood routine and blood biochemical tests were analyzed. And the single factor analysis of variance (ANOVA) was used to check the age related trend of BMD and VAT in both genders.Results:After screening the inclusion exclusion criteria and outliers of the main indicators, 86 113 people were enrolled in the project. The enrollment rate was 92.47%, including 35 431 (41.1%) women and 50 682 (58.9%) men, and the ratio of men to women was 1.43. The mean age was (50.3±12.7) years in all the subjects, and it was (50.2±12.8) years and (50.4±12.5) years in men and women, respectively, and there was no statistical difference between the two genders ( P>0.05). Total of 43 833 people were enrolled in east China, it was the largest group by region (50.90%), it was followed by central China (16 434 people, 19.08%), and the number of people enrolled in Northeast China was the lowest (2 914 people, 3.38%). The rate of completing of health information indicators related to the main outcome of the study were all above 70%, and there were significant differences between men and women (all P<0.05). The mean BMD was (139.33±46.76) mg/cm 3 in women, (135.90±36.48) mg/cm 3 in men, which showed a decreasing trend with age in both gender (both P<0.001); the mean intra-abdominal fat area was (116.39±56.23) cm 2 in women, (191.67±77.07) cm 2 in men, and there was an increasing trend with age in both men and women (both P<0.001). Conclusions:There are gender differences in BMD and VAT measured by QCT with different age tendency, and there are gender differences in health information index. Regional factors should also be taken into account for regional differences in the inclusion of data.

Objective:To investigate the normal reference values of spinal bone mineral density measured by quantitative computed tomography (QCT) and the differences of bone mineral density (BMD) in different regions of in Chinese adult males.Methods:Men who underwent low-dose CT lung scan for cancer screening in regions of Northeast, North, East, South, Central and Southwest of China from January 2018 to December 2019 were selected. And the lumbar vertebrae BMD values in the male subjects were measured by the QCT system (Mindways Software, Inc.). The mean BMD values and their decline rates were calculated at an age interval of 10 years, and the prevalence of osteoporosis was calculated according to the American College of Radiology spine QCT osteoporosis diagnostic criteria.Results:A total of 50 682 males with a mean age of (50.22±12.79) years (ranged 20 to 98 years) were included in this study. The peak BMD of (173.11±28.56) mg/cm 3 in the healthy Chinese adult male population appeared in the age group of 20 to 29 years and then declined with age. Before the age of 70 years, the BMD was relatively higher in males in South China, and it was lower in Central China and Southwest China, and it was intermediate in Northeast, North and East of China, with statistically significant differences. There was no significant differences in BMD in the males in the two age groups of 70 to 79 years and 80 and older among the regions in China. The overall decline rate of spinal BMD in Chinese males under QCT was about 46.92% over the lifetime, and it declined obviouslyin the 40-49 age group. The overall prevalence of osteoporosis in Chinese male population aged 50 years and above was approximately 11.42%, with the highest prevalence in Southwest China and Central China (14.72% and 13.87%, respectively) and the lowest in North China and South China (8.53% and 7.71%, respectively). Conclusions:A reference of lumbar spine BMD values for healthy males in China based on QCT is established. BMD values were highest in South China and Lowest in Central China.

Objective:To establish the normal reference value of lumbar bone mineral density (BMD) under quantitative CT (QCT) in Chinese healthy adult females and to explore the regional differences.Methods:Total of 35 431 healthy women who met the inclusion criteria of Chinese health quantitative CT big data program were selected in this study. The BMD of the central plane of L 1 and L 2 vertebrae was measured by Mindways′s QCT system, and the mean value was taken. One-way analysis of variance was used to compare the BMD differences of lumbar vertebrae in women of different ages and regions. The subjects were grouped by an age interval of 10 years, and the level of BMD in different regions of the same age group were compaired. Results:The peak BMD of Chinese healthy adult women appeared in the age group of 20-29 years (Northeast China(183.01±24.58) mg/cm 3, North China (188.93±24.80) mg/cm 3, East China (187.54±27.71) mg/cm 3, South China (186.22±33.72) mg/cm 3, Central China (176.33±24.91) mg/cm 3, Southwest China(182.25±28.00) mg/cm 3), and then it decreased with age. The level of BMD in different regions decreased with the age. Before the age of 70 years, BMD in Central and Southwest China was always at a low level((176.23±24.91) to (90.38±28.12) mg/cm 3, 182.25±28.00 to (88.55±25.68) mg/cm 3), lower than those in Northeast China ((183.01±24.58) to (99.69±27.85) mg/cm 3), North China ((188.93±24.80) to (95.89±26.12) mg/cm 3), East China ((187.54±27.71) to (95.65±27.86) mg/cm 3). After 70 years of age, BMD tended to be the same in different regions ( P>0.05). The BMD values in Central China and Southwest China were similar in the age group of 40-60 years ( P>0.05). The BMD values in the health adult femles in the age group of 60 years in different regions of Chinawere all lower than those of bone mass abnormality (all P<0.05). The detection rate of osteoporosis in females over 50 years was the highest in Southwest China (25.65%) and it was the lowest in North China (17.30%). Conclusions:This study establishes reference values of BMD under QCT in healthy Chinese women, which can be used as a reference basis for identifying women with low BMD who are at risk of osteoporosis. The BMD value is the lowest in Southwest China and the highest in South China.
