Systemic sclerosis is an autoimmune rheumatic disease that often leads to multisystem diseases,frequently resulting in pulmonary interstitial fibrosis.According to the theory of sanjiao(triple energizers)membranous channels,sanjiao connects the five zang-organs and six fu-viscera internally and the skin,muscles,and bones externally.It serves as a four-way membranous channel that connects internal organs and external structures,linking with the micromembranes of organs and blood vessels.The pathogenesis of pulmonary interstitial fibrosis secondary to systemic sclerosis involves external cold obstructing the skin and interstitial layers,impairing the defense qi and defense yang,which originate in the essence of the kidney.This leads to weak defensive qi and kidney deficiency,causing stagnation in sanjiao's energy flow and disruption of water and gasification and loss of fluid,resulting in accumulation of dampness,phlegm,and blood stasis.These obstructive factors spread along sanjiao's membranous channels,leading to multiorgan micromembrane involvement and systemic damage.The lungs,which are in direct contact with the external environment,are particularly susceptible to invasion by external pathogens.When combined with stagnation of dampness,phlegm,and blood in the lungs,this leads to secondary pulmonary fibrosis,resulting in lung dysfunction.Continuous stagnation of sanjiao exacerbates the overall condition of the patient,leading to a mixed cold-heat imbalance.Treatment focuses on"unblocking,transforming,and regulating"to restore sanjiao function,promote qi and fluid circulation,invigorate blood,and adjust the cold-heat imbalance,ultimately restoring the overall condition of the patient.

Objective To observe the efficacy and safety of Yifei Sanjie Decoction in the treatment of multiple pulmonary nodules.Methods A prospective randomized controlled clinical study was conducted to select 189 patients with multiple pulmonary nodules who saught medical attention at the Pulmonary Nodule Diagnosis and Treatment Center of Dongfang Hospital,Beijing University of Chinese Medicine and the Department of Thoracic Surgery of Beijing Shijitan Hospital Affiliated to Capital Medical University from January 2023 to March 2025.According to the random number table method,126 cases were randomly divided into the trial group and 63 cases in the blank control group at a ratio of 2∶1.The trial group was treated with modified Yifei Sanjie Decoction,and the blank control group was only followed up without intervention.The course of treatment was 3 months.The patients in the two groups were reexamined with lung CT after 3 months.The efficacy was evaluated by the area reduction rate of the major pulmonary nodules and the cumulative multiple pulmonary nodules in patients with multiple pulmonary nodules combined with the average diameter and malignant signs.According to the property of the major pulmonary nodules,we divided the patients into ground glass,solid,and mixed ground glass subgroups to evaluate the efficacy of different types of pulmonary nodules.We evaluated the change of malignant risk of pulmonary nodules according to the change of Mayo score.We evaluated the safety of the treatment medicine by blood routine,urine routine,and liver and kidney function.Results A total of 175 patients completed the study,117 in the trial group and 58 in the blank control group.The total effective rates of the major pulmonary nodules and the cumulative multiple pulmonary nodules in the trial group were 41.03%and 42.74%,respectively,the total effective rate of nodule number change was 29.91%which were significantly higher than those in the blank control group(P<0.05).In the trial group,the total effective rates of the major pulmonary nodules in the ground glass(72 cases),solid(28 cases),and mixed ground glass(17 cases)subgroups were 40.28%,32.14%,and 58.82%,respectively,the total effective rates of the cumulative multiple pulmonary nodules were 38.89%,42.86%,and 58.82%,respectively,which were significantly higher than those in corresponding subgroups of ground glass(37 cases),solid(14 cases),and mixed ground glass(7 cases)of the blank control(P<0.05).After treatment,the average diameter,area,and Mayo score of the major pulmonary nodules and the cumulative multiple pulmonary nodules in the trial group were significantly lower than those in the blank control group and before treatment(P<0.05),the average diameter,area,and Mayo score of the major pulmonary nodules and the cumulative multiple pulmonary nodules in the ground glass,solid,and mixed ground glass subgroups were lower than those in corresponding subgroups of the blank control group,and significantly lower than those before treatment(P<0.05).The number of nodules and malignant signs in the trial group were lower than before,while those in the blank control group were higher than before.There were no serious adverse events in the two groups during the study.Conclusion Yifei Sanjie Decoction can effectively treat the major pulmonary nodules and the cumulative multiple pulmonary nodules in patients with multiple pulmonary nodules,reduce the average diameter and area of nodules,reduce the Mayo score,and reduce the malignant signs and number of nodules.In the ground glass,solid,and mixed ground glass groups,the curative effect is well,and the safety is high,it can be used for the clinical treatment of multiple pulmonary nodules.

Objective To investigate the clinical characteristics,distribution of traditional Chinese medicine(TCM)syndrome types,and the anxiety and depression status in patients with colorectal polyps.Methods From January 2022 to December 2023,a total of 200 cases of patients with colorectal polyps(polyp group)and 100 patients without intestinal abnormalities(non-polyp group)under colonoscope who received colonoscopy or treatment at the Endoscopy Center of Dongguan Hospital,Guangzhou University of Chinese Medicine were enrolled.The relevant medical information of the patients in the two groups were collected,and then TCM syndrome differentiation of patients with colorectal polyps were carried out,the general infromation including gender,age,body mass index(BMI),smoking history and alcohol-intake history was recorded,and Hospital Anxiety and Depression Scale(HAD)score was calculated for assessing their anxiety and depression status.Results(1)The investigation of clinical characteristics showed that between the polyp group and the non-polyp group,the differences in the general information of gender,age,BMI,smoking history and alcohol-intake history were statistically significant(P<0.05 or P<0.01).As for the gender,the polyp group was predominated by the male(63.5%),while the non-polyp group was predominated by the female(58.0%),indicating that male patients were more likely to suffer from colorectal polyps.In terms of the age,the age group of 51-60 years old accounted for a higher percentage(36.0%)in the polyp group,while the age group of 41-50 years old accounted for a higher percentage(38.0%)in the non-polyp group,indicating that the polyp group had an elder average age than the non-polyp group.In addition,the percentages of patients with obesity(BMI≥28.0 kg/m2),smoking history,and alcohol-intake history in the polyp group were higher than those in the non-polyp group.(2)The analysis of features of colorectal polyps showed that the polyps were mostly seen in the left colon,accounting for 53.5%in the polyp group;adenomatous polyps accounted for 57.0%of all polyps;the size of colorectal polyps was usually less than one centimeter,accounting for 81.5%of all polyps;single colorectal polyps accounted for 45.5%,and multiple colorectal polyps accounted for 54.5%,indicating that colorectal polyps were usually multiple.(3)Among the 200 patients with colorectal polyps,there were 93 cases of syndrome of stagnation dampness due to spleen deficiency(46.5%),59 cases of dampness-heat in large intestine syndrome(29.5%),27 cases of liver depression and qi stagnation syndrome(13.5%),and 21 cases of dampness and blood stasis obstruction syndrome(10.5%).There were no statistically significant differences in the distribution of TCM syndrome types among colorectal polyp patients with different genders,ages,BMIs and alcohol consumption(P>0.05).The difference in the distribution of TCM syndrome types among colorectal polyp patients with or without smoking history was statistically significant(P<0.05).No statistically significant differences were shown in the distribution of TCM syndrome types among the colorectal polyp patients with various foci,number of polyps,and pathological types(P>0.05).The difference in the distribution of TCM syndrome types in colorectal polyp patients with different polyp sizes was statistically significant(P<0.05).In the patients with the polyp size0.05).In addition,the differences of anxiety scores and depression scores in the patients with various TCM syndrome types were not statistically significant(P>0.05).Conclusion(1)The distribution of TCM syndrome types of colorectal polyps is predominated by the syndrome of stagnation dampness due to spleen deficiency and dampness-heat in large intestine syndrome.The distribution of TCM syndrome types has no correlation with anxiety and depression,and the polyp foci,number of polyps,and pathological types of polyps,but has certain correlation with the size of the polyps.(2)Anxiety and depression may be the risk factors for colorectal polyps,but the polyp foci,number of polyps,and pathological types of polyps have no correlation with anxiety and depression,and the size of polyps may have certain correlation with anxiety.(3)Gender,age,smoking history and alcohol-intake history may be the risk factors for colorectal polyps.

Objective:To design and develop a cone-beam CT imaging system for small animals with continuously adjustable spatial resolution.Methods:The imaging system used an X-ray source with a focal spot size of 30 μm and a flat panel detector with a pixel size of 100 μm. On this premise, a " stepping-focusing-rotating" image acquisition mode was proposed, in which the " focusing" and " stepping" systems were sequentially embedded in the " rotating" system. In this acquisition mode, the X-ray source and flat panel detector were relatively stationary to form the " focusing" system. When the " stepping" system accurately transported the object to the scanning position, the " focusing" system could achieve adjustable spatial resolution by making linear motion around the object to be scanned according to different experimental requirements. Finally the " rotating" system achieve high-quality imaging.Results:The variable spatial resolution of small animal CBCT ranges from 35.7 μm to 71.4 μm, and the FOV ranges from 39.6 mm to 108.0 mm. The conversion time for the limit spatial resolution is 19.125 s, which allowed accurate 3D reconstruction of normal mice at different resolutions with high reproducibility.Conclusions:A cone-beam CT suitable for small animals has been developed, whose spatial resolution and FOV can be adjusted arbitrarily within a certain range, which can meet the different imaging requirements in rodent experiments.
