RESUMO

ObjectiveTo identify and analyze the possible influencing factors of obesity among public primary school students in Minhang District, Shanghai. MethodsBasic data, collected through questionnaire stars, was imported with merged physical examination data into Excel to form a database. Data were collected by questionnaire and analyzed by SPSS 22.00. Independent sample t-test was used for the data with normal distribution. Nonparametric test was used for the data with non-normal distribution. χ2 test was used for the quantitative data. Logistic regression was used for univariate and multivariate analysis. ResultsAccording to the national physical health standards for students (revised in 2014) , the prevalence rate of obesity among primary school students in Minhang district was 29.63% . The prevalence of overweight and obesity was 32.1% in boys and 26.9% in girls. The trend of overweight and obesity in different grades was similar among different genders .A single factor analysis showed that, being the only child (χ2=9.300, P<0.01) , father obesity(χ2=106.417, P<0.001) or mother obesity(χ2=118.534, P<0.001) , mother's overweight during pregnancy (χ2=159.731, P<0.001) , caregiver's role as grandparents (χ2=38.736, P<0.001) , low education level (χ2=111.309, P<0.001) had effects on overweight and obesity of children while the differences had statistical significance. Pupil's bad eating habit (χ2=18.905,P<0.001) and preference (χ2=22.901, P<0.001) , insufficient sleep time (χ2=61.685, P<0.001) , long-time using of electronic products (χ2=37.182, P<0.001) and low-time of exercise (χ2=15.328, P<0.001) also affected the obesity of primary school students. Among the five factors of family, diet, psychology, static state and dynamic state, the influencing factors of obesity in primary school students from grade one to grade four were being the only child, obese father and/or mother, overweight mother during pregnancy, caregivers without higher education. In terms of diet, it was mainly based on eating habits before bedtime, as well as partial and picky eating habits. In terms of psychology, the main psychological source was the pressure of learning in school. There was a clear relationship between the pace of learning and not keeping up. Static analysis revealed a correlation with lack of sleep. After assigning values based on eye hygiene recommendations for the use of electronic products, it was found that there was no direct correlation between obesity in primary school students and the duration of electronic product use. Dynamic analysis showed that not taking part in school physical exercise was related to obesity. ConclusionThe obesity of primary school students is influenced by family, diet, psychology, static and dynamic factors. The intervention of obesity in primary school needs the joint efforts of school, society, family, self-cognition and so on.

RESUMO

In order to provide a reference basis for the development of relevant compound preparations, this article takes a comprehensive analysis of the usage and dosage of famous classical formulas in Han dynasty from various perspectives, and gives corresponding countermeasures on this basis. Through the comprehensive analysis of the classification and statistics of Zhongjing's medication characteristics, decoction methods, administration and dosage, and combining conversion methods of weights and measures by ancient medical practitioners, along with the dosage and administration of the listed Han dynasty famous classical formulas, it was found that the "Jiangxi method" served as a general guideline for administration according to Zhongjing's original text. This method allowed for flexible dosing based on the conversion of the ancient measurements to modern equivalents[13.8 g per Liang(两)], ensuring the safe and effective medication of these formulas. After combing, it is found that although the dosage of single medicine is large in famous classical formulas from Han dynasty, the administration is flexible. The crude drug amount per administration serves as the foundational dose, with the frequency of administration adjusted flexibly according to the condition. This dosing approach becomes the key for the rational development of compound formulations of famous classical formulas. Based on the conclusions of the study, it is recommended that when developing compound formulations of famous classical formulas in Han dynasty, the original administration method and dosage should be respected. The original crude drug amount per administration should be considered as the daily foundational dose, with the frequency of administration described within a range(1 to N times per day, where N is the maximum number of administrations as per the original text). The specific frequency of administration can be adjusted flexibly by clinical practitioners based on the individual condition. This approach should also be adopted in toxicological studies, where the dosage per administration serves as the basis for toxicity research, and the toxicity profile at the maximum administration frequency should be observed, providing guidance on the clinical safety range. Corresponding drug labels should provide information within a range to indicate toxicological risk intervals.

RESUMO

The clinical value of Chinese patent medicine is the core direction of the development of the traditional Chinese medicine industry. The precise clinical positioning determines the way to prove the value of the drug, and is a key link to highlight the clinical value. This paper presented a case study of clinical positioning for Chinese patent medicine, namely Qizhi Tongluo capsules, and the key technical framework of precise clinical positioning of Chinese patent medicine, which was manifested as a comparison of prescription target spectral effect, discovery of core value of prescription, and confirmation of clinical positioning trial. The technical framework was designed to address a range of issues in the realm of precise clinical positioning. Before the clinical positioning trial, based on the multi-component, multi-target, and multi-phenotype data of prescription and clinical indication, the multi-omics network analysis technology was used to identify the core value of the traditional Chinese medicine varieties and predict the potential clinical advantages. Then, based on the predicted clinical advantages, reasonable efficacy indicators were selected, and the clinical efficacy was judged and verified by dynamic and flexible innovative clinical trials to improve the success rate of clinical positioning. This research paradigm integrates "omics technology" with "evidence-based" principles and follows the "precise evidence-based" concept. This research aims to provide a new strategy and method for the precise medication and positioning of Chinese patent medicine with traditional Chinese medicine characteristics after being put into the market and provide more technical thinking for traditional Chinese medicine to move towards precise medicine.

RESUMO

Danggui Sinitang is first recorded in the Treatise on Cold Damage written by ZHANG Zhongjing in the Han dynasty. It is composed of Angelicae Sinensis Radix, Cinnamomi Ramulus, Paeoniae Radix Alba, Asari Radix et Rhizoma, Glycyrrhizae Radix et Rhizoma, Tetrapanacis Medulla, and Jujubae Fructus and serves as a classic formula for treating the syndrome of blood deficiency and cold reversal. This study systematically reviews the records of Danggui Sinitang in ancient Chinese medicine books of various dynasties and the modern clinical applications to probe into the composition, plant species, processing, dosage, decocting method, and indications of Danggui Sinitang, aiming to provide a reference for the development and clinical application of this classic formula. The review of the records showed that there were a variety of records of Danggui Sinitang with different composition, and the composition of this formula listed in the Treatise on Cold Damage has a significant impact on later generations and has been used by medical practitioners throughout history. Although the dosage of some drugs decreased during the Ming and Qing dynasties, the medical practitioners continued to use the original formula. In terms of processing, although there were slight changes in the processing of Angelicae Sinensis Radix, Paeoniae Radix Alba, Glycyrrhizae Radix et Rhizoma, and Tetrapanacis Medulla, the original processing method was inherited. In terms of indications, Danggui Sinitang was designed to treat cold reversal due to blood deficiency and dysentery. Furthermore, it was used to treat headache, convulsive disease, infantile convulsion, and private part adduction in the Ming and Qing dynasties. Nowadays, this formula is mostly used to treat diabetes peripheral neuropathy, rheumatoid arthritis, dysmenorrhea, Raynaud's disease and other diseases. In terms of precautions, ancient physicians believed that Danggui Sinitang should not be taken by pregnant women and should only be used for limb chills caused by blood deficiency and cold coagulation. For limb chills caused by other reasons, this formula should not be used indiscriminately. Modern research has not reported any serious adverse reactions related to this formula. Danggui Sinitang has a definite therapeutic effect. In subsequent research and development, quality control standards of Danggui Sinitang should be established while its safety is ensured, and the related preparations should be developed and applied.

RESUMO

OBJECTIVE@#To compare the clinical efficacy between electroacupuncture(EA) and moxibustion for neurogenic bladder (NB) after spinal cord injury (SCI).@*METHODS@#One hundred and twenty patients with NB after SCI were randomly divided into an EA group, a moxibustion group, and an intermittent catheterization group, with 40 patients in each group. The patients in the intermittent catheterization group were treated with routine treatment and intermittent catheterization, while the patients in the EA group and the moxibustion group were treated with additional treatments of EA (discontinuous wave, with a frequency of 1.3-1.6 Hz, and intensity based on patient tolerance) and moxibustion, respectively. The acupoints used in both groups were Zhongji (CV 3) and Guanyuan (CV 4), bilateral Zusanli (ST 36), Yinlingquan (SP 9), and Baliao points. Each session lasted for 30 min, once daily, six times a week, for a total of six weeks.The maximum bladder capacity (MBC), residual urine vdume (RUV), detrusor pressure (Pdet) during the filling phase, bladder compliance (BC), maximum renal pelvis separation width of both kidneys, urine white blood cell count, TCM syndrome score, and World Health Organization quality of life assessment-BREF (WHOQOL-BREF) score were compared before and after treatment in the 3 groups. The number of patients in each group who achieved bladder functional balance was recorded, and the clinical efficacy was assessed after treatment.@*RESULTS@#After treatment, the MBC, Pdet, BC, and WHOQOL-BREF scores in the EA group and the moxibustion group were increased (P<0.05), while the RUV, maximum renal pelvis separation width of both kidneys, urine white blood cell count, and TCM syndrome scores were decreased (P<0.05, P<0.01). In the intermittent catheterization group, MBC, RUV, maximum renal pelvis separation width of both kidneys, and urine white blood cell count were decreased (P<0.05), while BC and WHOQOL-BREF score were increased (P<0.05) after treatment. After treatment, the MBC, Pdet, BC, and WHOQOL-BREF scores in the EA group and the moxibustion group were higher than those in the intermittent catheterization group (P<0.05), while the RUV and TCM syndrome scores were lower than those in the intermittent catheterization group (P<0.05). Moreover, after treatment, the MBC and Pdet in the moxibustion group were higher than those in the EA group (P<0.05), while the RUV, maximum renal pelvis separation width of both kidneys, and TCM syndrome score in the EA group were lower than those in the moxibustion group (P<0.05). The number of patients who achieved bladder functional balance after treatment in the EA group and the moxibustion group was higher than that in the intermittent catheterization group (P<0.05). The cured and effective rate was 85.0% (34/40) in the EA group and 82.5% (33/40) in the moxibustion group, which were both higher than 65.0% (26/40) in the intermittent catheterization group (P<0.05), there was no significant difference between the EA group and the moxibustion group (P>0.05).@*CONCLUSION@#EA and moxibustion could effectively improve the functional state of bladder in patients with NB after SCI. EA is more effective in reducing residual urine volume and excessive activity of the urethral sphincter, and relieving TCM syndromes, while moxibustion is more effective in increasing the pressure of the detrusor during the filling period and establishing the detrusor reflex.

RESUMO

ObjectiveTo develop a new mosquito trap and evaluate its effectiveness in Aedes albopictus monitoring in an urban community. MethodsThe first-round field test was conducted in a well-greened residential neighborhood with high Aedes albopictus density calculated by human landing catch in August 2022, in Minhang District, Shanghai. 65 new test containers with different designs were randomly deployed in the field. These trap containers were designed by different material, color, hole size, shape and top cover colors. The results of mosquito and its egg trapping were observed and recorded continuously for 7 days. In September 2022, the second round of experiment was conducted. After comparison, an optimized trap container was designed. 140 new trap containers were compared with 140 traditional ones to evaluate the effectiveness. SPSS 22.5 software was used for statistical analysis. ResultsThere were significant changes in the outcome of mosquito and its egg trapping on the 4th and 7th day of the pre-experiment deployment of the three kinds of containers. The 200 ml container cup with three round holes in the body had the best effect on trapping mosquitos and eggs, with a positive rate of 45.5% (5/11), while other type of contrainer cup only had a positive rate of 12% (6/50) in trapping mosquitos and eggs. Statistical significant differences (χ2=45.443,P <0.001) existed between the two tpyes of cups within the first kind of trapping container. The second kind of trapping container showed round and oval holes had better effect on mosquito trapping, with a positive rate of 55.6% (5/9). The third kind of hanging container can resist strong wind. The best mosquito trapping effect of three round holes was 66.7% (2/3). The container wall should not be made of rough material, which was easy to cause the escape of adult mosquitoes. Combined with the three types of containers, the new contariner should be top transparent, and the top 1/3 of the side should paint black with 3 round holes. The effective recovery rate of the new container was higher than that of the traditional one under the exclusion of human factors, and had the advantage of preventing rain, wind and rollover, but the effect of trapping mosquito and its egg was comparable to the traditional one(χ2D4=0.197,P=0.658; χ2D7=0.125 ,P=0.724). ConclusionThis new type of mosquito trap is worth further exploration and research, which can improve the trapping efficiency, overall recovery rate and the accurate confirmation of the mosquito density.

RESUMO

BACKGROUND@#Ever-growing tissue regeneration causes pressing need for large population of stem cells. However, extensive cell expansion eventually leads to impaired regenerative potentials. In this study, chromobox protein homolog 7 (CBX7) was overexpressed to rejuvenate late passage dental pulp stem cells (DPSCs-P9). @*METHODS@#The recruitment of copper ions (Cu2+ )-activated hypoxia-inducible factor-1a (HIF-1a) to the CBX7 gene promoter was confirmed by chromatin immunoprecipitation assay. Functions subsequent to Cu2+ -induced or recombinant overexpression of CBX7 on proliferation, multipotency, odontoblastic differentiation and angiogenesis were investigated in vitro, while murine subcutaneous transplantation model was used to further detect the effects of Cu2+ -induced CBX7 overexpression in vivo. @*RESULTS@#Our data displayed that CBX7 overexpression maintain proliferation and multipotency of DPSCs-P9 almost as strong as those of DPSCs-P3. Both gene level of odontoblast-lineage markers and calcium precipitation were nearly the same between CBX7 overexpressed DPSCs-P9 and normal DPSCs-P3. Moreover, we also found upregulated expression of vascular endothelial growth factor in DPSCs-P9 with CBX7 overexpression, which increased the number of capillary-like structures and migrating co-cultured human umbilical vein endothelial cells as well. These findings indicate CBX7 as an effective factor to rejuvenate late passage stem cells insusceptible to cell expansion. Cu2+ has been proved to achieve CBX7 overexpression in DPSCs through the initiation of HIF-1a-CBX7 cascade. Under Cu2+ stimulation since P3, DPSCs-P9 exhibited ameliorated regenerative potential both in vitro and in vivo. @*CONCLUSION@#Long-term stimulation of Cu2+ to overexpress CBX7 could be a new strategy to manufacture large population of self-renewing stem cells.

RESUMO

ObjectiveTo evaluate the quality of Mori Cortex from different producing areas by the entropy weight-technique for order preference by similarity to an ideal solution(TOPSIS), and to provide a new evaluation method for the quality control of Mori Cortex. MethodAccording to the five key indexes of color, thickness, texture, powdery and cortex remain, a subjective scoring table was designed to evaluate the appearance of Mori Cortex. High performance liquid chromatography(HPLC) was used to determine the fingerprint and the contents of multiple components(mulberroside A, chlorogenic acid, oxyresveratrol, mulberroside C, sanggenone D, sanggenone C, morusin), and chemometrics was used to explore the differential components of Mori Cortex from different habitats. On this basis, TOPSIS was used to comprehensively evaluate the quality of Mori Cortex from different habitats, and SPSS 22.0 software was used to carry out bivariate correlation analysis between thickness and appearance color with contents of seven components of Mori Cortex. ResultThose with lighter color, thicker root bark, tougher texture, sufficient powder and less cortex remain scored higher, and the top five were all from Anhui. The established fingerprint and determination methods were stable and reliable. Partial least squares-discriminant analysis(PLS-DA) screened three components with the variable importance in the projection(VIP) value>1(mulberroside A, sanggenone D, sanggenone C), which made an important contribution to the difference in the origin of Mori Cortex. Correlation analysis showed that there was a significantly positive correlation between mulberroside C with lightness value(L*) and total chromaticity value(E*ab) and mulberroside A with yellow-blue value(b*)(P<0.05, P<0.01), a significantly negative correlation between sanggenone C with b* and between morusin with L*(P<0.05, P<0.01). And there was a significantly negative correlation between mulberroside A, chlorogenic acid, and morusin with thickness(P<0.01), a clearly negative correlation between sanggenone D with thickness(P<0.05), a significantly positive correlation between sanggenone C with thickness(P<0.01). TOPSIS comprehensive scores showed that the samples from Anhui had a good score and ranked high. ConclusionThere are great differences in the quality of Mori Cortex from different habitats, and those with the close habitats show similar characteristics in appearance and component content, and lighter color and less cortex were positively correlated with the quality. Among them, the quality of Mori Cortex from Anhui is relatively good.

RESUMO

This article has systematically reviewed the name, origin, scientific name, producing area, quality evaluation, harvesting and processing methods of Polygonati Odorati Rhizoma(POR) by consulting the materia medica, medical books, prescription books and modern literature, in order to provide a reference for the development of famous classical formulas containing POR. Yuzhu was first recorded in the Shennong Bencaojing under the name of Nyuwei. After that, Weirui was used as the rectification name in the subsequent dynasties, and in recent times, the name of Yuzhu is mostly used in materia medica and prescription books. In ancient times, there were different names for Yuzhu, such as Nyuwei, Weiwei and Weirui. The names of the three are similar and there was a mixed use of the same name and foreign matter in history. In the Tang dynasty, SU Jing listed Nyuwei with the effect of curing dysentery in the intermediate of herbal part of Xinxiu Bencao according to its different efficacy. However, based on Shennong Bencaojing, Mingyi Bielu and the different energy efficiency of medical prescriptions, SU Song of the Northern Song dynasty believed that the three were medicinal materials of different origins. In short, the names of the three have been unclear in history for a long time. According to the development of the time line, this paper examines the names and realities of the three, and concludes that the two(Weiwei and Weirui) are the same medicinal material, that is, Polygonatum odoratum of Liliaceae, and the Nyuwei is Clematis apiifolia of Ranunculaceae, and the source relationship of the three is clarified. The mainstream source of Yuzhu used in the past dynasties was the rhizome of P. odoratum, which was widely distributed in the wild and has a large amount of resources. The origins of Yuzhu recorded in ancient times were mainly Taishan in Shandong, Chuzhou and Shuzhou in Anhui, and Hanzhong in Shaanxi, in modern times, it was produced in northern Hebei and Shaoyang in Hunan with high quality, and in the modern times, Jiangbei Yuzhu from Haimen in Jiangsu, Anyuzhu from Nanling, Anqing and Tongling in Anhui, Guanyuzhu from Fengrun, Yutian, Zunhua, Huailai in Hebei and Suizhong, Jinxi, Jianchang, Lingyuan, Liaoyang, Haicheng, Gaiping in Liaoning, Xiangyuzhu from Shaoyang in Hunan are the authentic medicinal material. In ancient times, the quality of Yuzhu was good if it was fat and white, while in modern times, it is better with thick roots, bright yellow color, soft texture, no stiff skin and no oiliness. In ancient times, the origin processing of POR was mostly dried in the shade, but in modern times, it is mostly sun-dried or dried after steaming and rubbing. The ancient processing was mostly scraped off the skin and soaked in honey water and then steamed through, while the modern one is mostly washed and cut into thick slices for raw use. Based on the conclusion of the herbal textual research, it is suggested that the rhizome of P. odoratum of Liliaceae be used as the source for the development of famous classical formulas, and the corresponding specifications be selected according to the processing requirements of the prescription. In view of the Yiweitang in Wenbing Tiaobian, which uses the method of frying fragrance to achieve the effect of fragrant refreshing the spleen, it can be processed by referring to the stir-frying method in the current version of Chinese Pharmacopoeia.

RESUMO

Since the emergence of the term "materia medica", scholars have proposed different opinions on its concept. This term has been used to refer to traditional Chinese medicines, or medical books, or traditional pharmacology. Due to the differences in the concept of materia medica, scholars also have controversies about the concept of herbalism. Herbalism is usually understood as traditional Chinese pharmacology. After years of evolution, the term "herbalism" has now possessed the characteristics of an independent discipline, which can be defined as an applied basic discipline that comprehensively utilizes traditional and modern technological methods to study the formation, development, and changes of traditional pharmacology and reveal the basic theories and application laws of traditional medicine. At present, the research content of herbalism mainly includes three aspects: materia medica history, materia medica literature, and traditional pharmacology. This study explores the disciplinary concepts and main research content of herbalism based on a systematic review of the literature about the concepts of materia medica and herbalism, with the aim of attracting more attention to promote the establishment and development of the discipline of herbalism.

RESUMO

Paeonia veitchii and P. lactiflora are both original plants of the famous Chinese medicinal drug Paeoniae Radix Rubra in the Chinese Pharmacopoeia. They have important medicinal value and great potential in the flower market. The selection of stable and reliable reference genes is a necessary prerequisite for molecular research on P. veitchii. In this study, two reference genes, Actin and GAPDH, were selected as candidate genes from the transcriptome data of P. veitchii. The expression levels of the two candidate genes in different tissues(phloem, xylem, stem, leaf, petiole, and ovary) and different growth stages(bud stage, flowering stage, and dormant stage) of P. veitchii were detected using real-time fluorescence quantitative technology(qRT-PCR). Then, the stability of the expression of the two reference genes was comprehensively analyzed using geNorm, NormFinder, BestKeeper, ΔCT, and RefFinder. The results showed that the expression patterns of Actin and GAPDH were stable in different tissues and growth stages of P. veitchii. Furthermore, the expression levels of eight genes(Pv-TPS01, Pv-TPS02, Pv-CYP01, Pv-CYP02, Pv-CYP03, Pv-BAHD01, Pv-UGT01, and Pv-UGT02) in different tissues were further detected based on the transcriptome data of P. veitchii. The results showed that when Actin and GAPDH were used as reference genes, the expression trends of the eight genes in different tissues of P. veitchii were consistent, validating the reliability of Actin and GAPDH as reference genes for P. veitchii. In conclusion, this study finds that Actin and GAPDH can be used as reference genes for studying gene expression levels in different tissues and growth stages of P. veitchii.

RESUMO

The establishment of core indicators for assessment plays an important role in carrying out the lifecycle value assessment of Chinese patent medicine, which are developed based on the concepts such as clinical value oriented, paying attention to the human use experience, and whole process quality control. To this end, the Specialty Committee of Data Monitoring and Decision Making of the World Federation of Chinese Medicine Societies organized experts to draft the Expert Consensus on Core Indicators for Lifecycle Value Assessment of Chinese Patent Medicine based on the research including Chinese Medicine Registration Review Evidence System in Combination of Traditional Chinese Medicine Theory, Human Use Experience, and Clinical Trials(GZY-FJS-2022-206) by National Administration of Traditional Chinese Medicine. This consensus proposed 92 core indicators from four stages, including new drug R&D project approval, pre-clinical research, new drug marketing authorization, and post-marketing, combining the assessment purposes and needs of different stakeholders from different dimensions such as clinical needs, clinical positioning, human use experience, effectiveness, safety, quality control, innovation, accessibility, and suitability. This consensus also interpreted the indicators to clearly elucidate the core elements of the value assessment of Chinese patent medicine in different R&D stages and guided the stakeholders to identify, analyze, and assess the value of Chinese patent medicine in the R&D and use process based on the core indicators in a scientific, objective, and standardized approach. This consensus is expected to play an important role in the high-quality new drug development, drug pricing and compensation of Chinese patent medicine, the development of clinical pathways, and rational clinical application.

RESUMO

OBJECTIVE@#To explore the coincidence rate of G-banding karyotype analysis and fluorescence in situ hybridization (FISH) for the diagnosis of children with sex chromosome mosaicisms.@*METHODS@#A retrospective analysis was carried out for 157 children with suspected sex chromosome abnormalities who had presented at Shenzhen Children's Hospital from April 2021 to May 2022. Interphase sex chromosome FISH and G-banding karyotyping results were collected. The coincidence rate of the two methods in children with sex chromosome mosaicisms was compared.@*RESULTS@#The detection rates of G-banding karyotype analysis and FISH were 26.1% (41/157) and 22.9% (36/157) , respectively (P > 0.05). The results of G-banding karyotype analysis showed that 141 cases (89.8%) were in the sex chromosome homogeneity group, of which only 5 cases (3.5%) were inconsistent with the results of FISH. There were 16 cases (10.2%) in the sex chromosome mosaicism group, of which 11 cases (68.8%) were inconsistent with the results of FISH. There was a statistical difference between the two groups in the coincidence rate of the results of the two methods (P < 0.05).@*CONCLUSION@#No significant difference was found between G-banding karyotype analysis and FISH in the detection rate of chromosome abnormalities. The coincidence rate in the mosaicism group was lower than that in the homogeneity group, and the difference was statistically significant. The two methods should be combined for clinical diagnosis.

RESUMO

Objective: To construct and verify a light-weighted convolutional neural network (CNN), and explore its application value for screening the early stage (subcategory 0/1 and stage Ⅰ of pneumoconiosis) of coal workers' pneumoconiosis (CWP) from digital chest radiography (DR) . Methods: A total of 1225 DR images of coal workers who were examined at an Occupational Disease Prevention and Control Institute in Anhui Province from October 2018 to March 2021 were retrospectively collected. All DR images were collectively diagnosed by 3 radiologists with diagnostic qualifications and gave diagnostic results. There were 692 DR images with small opacity profusion 0/- or 0/0 and 533 DR images with small opacity profusion 0/1 to stage Ⅲ of pneumoconiosis. The original chest radiographs were preprocessed differently to generate four datasets, namely 16-bit grayscale original image set (Origin16), 8-bit grayscale original image set (Origin 8), 16-bit grayscale histogram equalized image set (HE16) and 8-bit grayscale histogram equalized image set (HE8). The light-weighted CNN, ShuffleNet, was applied to train the generated prediction model on the four datasets separately. The performance of the four models for pneumoconiosis prediction was evaluated on a test set containing 130 DR images using measures such as the receiver operating characteristic (ROC) curve, accuracy, sensitivity, specificity, and Youden index. The Kappa consistency test was used to compare the agreement between the model predictions and the physician diagnosed pneumoconiosis results. Results: Origin16 model achieved the highest ROC area under the curve (AUC=0.958), accuracy (92.3%), specificity (92.9%), and Youden index (0.8452) for predicting pneumoconiosis, with a sensitivity of 91.7%. And the highest consistency between identification and physician diagnosis was observed for Origin16 model (Kappa value was 0.845, 95%CI: 0.753-0.937, P<0.001). HE16 model had the highest sensitivity (98.3%) . Conclusion: The light-weighted CNN ShuffleNet model can efficiently identify the early stages of CWP, and its application in the early screening of CWP can effectively improve physicians' work efficiency.
