It has been proposed by Basic Questions On Proper Therapies for Different Diseases Geographically （《素问·异法方宜论篇》） that "wei （痿） diseases should be treated by Daoyin （导引）". Furthermore， it is clarified that the indications of Daoyin are those conditions related to spleen and dampness caused by dampness pathogen， excessive food intake and less exercise， and mainly manifested as heavy limbs， fatigue and flaccidity， which is similar to the metabolic imbalance in the early stage of glucose or lipid metabolism disorder in modern medicine. Based on modern clinical and basic research evidence， Daoyin can inhibit the response of inflammation， alleviate oxidative stress， regulate intestinal microbiota， and modulate gene expression to improve metabolic abnormalities， and this will provide ideas for researches on the indications of Daoyin.

Leukemia is a type of common hematopoietic system tumor with fever, leukocytosis, anemia and hemorrhage as the main clinical symptoms. Leukemia can be divided into acute leukemia and chronic leukemia. TCM believes that leukaemia is closely related to latent pathogen and fire toxin. Based on the theory of "excessive qi is fire", this article believed that the pathogenesis of leukemia hemorrhage is the transformation of bone marrow pathological qi into fire, clarified the relationship between leukemia cells and "fire", and proposed that the basic principle of treatment should be strengthening the body and reduce fire, supplementing with methods such as clearing heat and detoxifying, tonifying qi and nourishing yin, so as to provide references for clinical treatment.

Objective:To explore the paths and goals of organized construction for scientific research platforms in large-scale hospitals under the background of organized scientific research in China.Methods:By reviewing the relevant literature, and analyzing the construction of existing international and domestic research platforms for organized scientific research, this article elaborated on the importance and necessity of building a research platform for clinical hospitals under the background of organized scientific research and made suggestions for the platform construction.Results:Organized scientific research requires the organized construction of scientific research platforms. The construction of organized scientific research platforms should always focus on the major national needs, serve major scientific plans, carry out organized talent training, and internal efficient and orderly organization and operation, under the principle of interdisciplinary and multi-level collaborative innovation and development.Conclusions:In response to the strategic needs of national science and technology in the 14-Five Year Plan, the hospital scientific research platforms should be upgraded, integrated, expanded, and improved in an organized way, to form a multi-disciplinary and cross-dimensional platform structure to ensure the smooth development of organized scientific research.

Objective:To improve awareness of the diagnosis and treatment of splenic histiocytic sarcoma.Methods:The clinical data of one patient with splenic histiocytic sarcoma who was admitted to First Teaching Hospital of Tianjin University of Traditional Chinese Medicine in July 2020 were retrospectively analyzed, and the relevant domestic and foreign literature was reviewed.Results:The patient was diagnosed as splenic histiocytic sarcoma by histopathological and immunohistochemical examinations. The methylprednisolone combined with cyclosporine was ineffective. The patient received a total splenectomy, followed by chemotherapy with VECD and CHOP regimens. The patient's condition was stable during the 5-month follow-up after the operation. The result of bone puncture showed that there was no infiltration of histocytic sarcoma, and hematological remission was obtained.Conclusions:Splenic histocytic sarcoma is a highly malignant tumor with insidious onset, unclear pathogenesis, and lack of specificity in clinical manifestations and imaging examinations. The diagnosis depends on pathological biopsy and immunohistochemistry, and needs to be differentiated from other malignant tumors of lymphoid hematopoietic tissue. At present, there is no best treatment for splenic histiocytic sarcoma, and most patients have a poor prognosis.

Objective:To share the practice of medical care and rescue in the 2017-2019 Amne Machin extreme cross-country challenge.Methods:At the invitation of the Organizing Committee of Amne Machin extreme cross-country challenge of Maqin County of Qinghai Province. More than 150 medical personnel were sent to make the rescue plan and implement the medical security for three consecutive years. The support was divided into leading command group, expert consulting group, on-site medical support group, rear medical support group, and medical material support group. The on-site medical support group was equipped with the ambulance, corresponding emergency medical equipments and medicines to provide medical support at eight medical stations from the starting point to the endpoint and along the route between each station.Results:There were no cardiac arrest and sudden death cases during the three competitions. A total of 56 patients (5 cases of combined injuries) were received, including 21 cases of mild altitude reaction, 8 cases of abrasions, 13 cases of muscle spasm and strain, 11 cases of hypoglycemia, and 3 cases of abdominal pain. All the injured were treated and observed in time. Each patient achieved a complete remission.Conclusions:To achieve the success of medical security of the highest average altitude cross-country race certified by International Trail Running Association (ITRA), we must formulate a scientific and perfect medical security work plan in the first place: pre competition physical examination, especially the application of sports cardiopulmonary function test, screen out athletes who may have medical accidents; during the competition, focus on monitoring and tracking the players who may have problems; each support point is closely connected with the support vehicle; do a good job of first aid training for all kinds of personnel, so that medical accidents can be found, aided, and transferred at the first time. The medical care and rescue of Amne Machin extreme cross-country challenge have played a good role in the security of the international plateau sports events, which provides a reference for the security of similar events.

Objective To investigate the drug resistance characteristics and epidemic trend of Escherichia coli in Anning, Yunnan, and to provide a reference for clinical rational use of antibiotics. Methods A total of 376 strains of Escherichia coli were isolated from June 2018 to June 2019 from Kungang Hospital of Yunnan Province. The ESBLs producing strains were screened by double disk method and the sensitivity of ESBLs to antibiotics was detected by K-B method. The genotyping of ESBLs strains and the class I, II and III integrase genes in integron 3^' and 5^' conservative regions was conducted using polymerase chain reaction (PCR). Results The detection rate of ESBLs producing Escherichia coli was 53.19% (200/376). ESBLs-producing Escherichia coli had a low resistance rate to carbapenem antibacterial drugs with a relatively high sensitivity. The resistance rates to amikacin and piperacillin were 7.50% and 12.50% respectively, which had good antibacterial activity. The resistance rate to other antibiotics was high. There were 74.00% (148/ 200) of ESBLs-producing Escherichia coli carrying CTX-M gene, 34.50% (69/200) carrying TEM genes, and 1.00% (2/200) of strains carrying SHV genes. In addition, there were 9.00% (18/200) of strains carrying both CTX-M and TEM genes, and 0.50% (1/200) of strains carrying both CTX-M and SHV genes. The detection rate of integrons accounted for 37.00% (74/200), all of which were class I integrons. Conclusion The prevalence of ESBLs-producing Escherichia coli was relatively high in Anning, Yunnan. ESBLs-producing Escherichia coli showed a trend of multi-drug resistance. The genotype was mainly CTX-M, and the integron was classified as class I.

Objective: To report 3 cases of multiple myeloma (MM) with lung cancer.Combined with literature review to improve the understanding of MM with lung cancer. Methods: The clinical characteristics, treatment and prognosis of 3 cases of MM with lung cancer in Shijingshan Teaching Hospital of Capital Medical University from January 2017 to December 2018 and the relevant literature were retrospectively reviewed. Results: Among the 3 patients, 2 cases were male and 1 case was female, with an average age of 69.7 years.The pathological type of lung cancer patients was adenocarcinoma, of which 2 cases were positive for EGFR gene mutation and 1 case was positive for ALK fusion gene.Three cases of multiple myeloma were all IgG-kappa light chain type, with stage Ⅲ A. The chemotherapy regimens used in MM patients were all PD regimen 4-6 cycles; one patient died of pulmonary infection, one patient had MM CR, but lung cancer progressed, one patient had MM very good partial remission (VGPR), and there was no recurrence of lung cancer. Conclusion The pathogenesis of second primary malignancy in MM is not clear, which needs further study.

Objective To explore the effect of oral-muscle biofeedback system training on the rehabilitation of cognitive dysfunction in patients with obstructive sleep apnea (OSA) after ischemic stroke.Methods A total of 60 cases of poststroke OSA patients with cognitive dysfunction admitted to the rehabilitation center of deAn hospital in changzhou city from June 2017 to March 2018 were selected.On the basis of routine rehabilitation treatment,the control group was given positive pressure ventilation treatment,and the observation group was given oral muscle biofeedback system training.The changes of polysomnography (PSG) parameters,Montreal cognitive assessment (MoCA) score,serum matrix metalloproteinase-9 (MMP-9) and plasma homcysteinemia (Hcy) expression levels in the two groups before and after treatment were compared.Results Apnea hypopnea index and maximum apnea time of the two groups were significantly decreased after treatment compared with those before treatment,and the lowest SpO2 and average SpO2 were significantly higher than those before treatment(P＜0.05).After treatment,MoCA total score and the dimensions score of patients in the observation group were significantly higher than those in the control group at the same time (P＜0.05).After treatment,the levels of Hcy((12.38±4.54) μmol/L) and MMP-9((124.52± 12.94) μg/L) in the observation group were significantly lower than those in the control group at the same time(Hcy(17.52±6.27) μmol/L,MMP-9(268.25±20.5 7)μg/L),and the difference was statistically significant (Hcy:t=3.637,P＜0.05;MMP-9:t =32.395,P＜0.05).Conclusions Positive pressure ventilation and oral muscle biofeedback system training have the same effect on OSA after stroke,but oral muscle biofeedback system training can also effectively improve patients' cognitive function.

Objective: To investigate the influential factors of efficacy of the first ¹³¹I ablation therapy for thyroid remnant in papillary thyroid microcarcinoma (PTMC) patients after thyroidectomy. Methods: Eighty-nine PTMC patients who underwent twice ¹³¹I ablation therapy and ¹³¹I whole body follow-up scan (¹³¹I-WBS) within 5 to 8 months in our department from September 2007 to October 2016 were identified and enrolled in present study. Patients were divided into complete-ablation group and uncomplete-ablation group according to whether or not radioactivity was detected at the thyroid bed in ¹³¹I-WBS. The χ² test and multi-variance Binary logistic regression were performed for the factors which might affect the therapeutic efficacy. Results: The first ¹³¹I ablation therapy was successful in 41 of 89 patients (46.07%). Residual thyroid weight was found to be associated with therapeutic efficacy (P<0.05), while gender, age, surgical method, lesions′maximum diameter, with or without LN metastasis, with or without distant metastasis, time of operation from first ¹³¹I treatment, lesions′number, thyroid stimulating hormone (TSH), thyroglobulin (Tg), the consistency of ¹³¹I-WBS and ⁹⁹Tc^m-pertechnatate, TNM stage, ATA risk, Tg/TSH ratio were not significant associated with therapeutic efficacy. Binary logistic regression analysis was performed in these respects and it indicated that residual thyroid weight and ATA risk were not statistically significant independent variable (P>0.05). Conclusions Residual thyroid weight might affect efficacy of the first ¹³¹I ablation therapy on thyroid remnant in PTMC patients after thyroidectomy, but it is not an independent factor. Multiple interrelated factors should be considered when predicting the efficacy of the first ¹³¹I ablation therapy.

Objective To observe the variation of phosphatidylinositol-3 kinase (PI3K),protein kinase B (AKT),sodium iodide symporter (NIS) mRNA and protein expression in rat mammary tissues and serum insulin growth factor Ⅰ (IGF-1) under different iodine nutrition levels,and to study the role of PI3K-AKT signaling pathway in the process of mammary gland intaking iodine during lactation period.Methods Totally 130 Wistar rats (100 female rats,30 male rats) were randomly divided into five groups with 20 female rats in each group:①control group (NI):was feed with normal diet and iodine content 50 μg/L in deionized water;②low iodine group 1 (LI1 group):was feed with low iodine diet and deionized water;③low iodine group 2 (LI2):was feed with low iodine diet and iodine content 5 μg/L in deionized water;④high iodine group 1 (HI1 group):was feed with normal diet and iodine content 3 000 μg/L in deionized water;⑤high iodine group 2 (HI2):was feed with normal diet and iodine content 10 000 μg/L in deionized water.After feeding for 3 months,females were mated with male rats,then male rats were taken out and every female rat was feed individually.Urinary iodine level of rats in lactation period 10 days after giving birth was tested.Blood and mammary tissue samples of rats in lactation period were taken after killing them.Enzyme linked immunosorbent assay (ELISA) was used to detect serum IGF-1 level,real-time fluorescence quantification PCR to detect the mRNA expression of mammary gland PI3K,AKT and NIS,Western blotting to detect mammary gland PI3K,total AKT,phosphorylation AKT (p-AKT) and NIS protein expression.Results The medians urinary iodine of lactation period rats in LI1 and LI2 (3.16,6.36 μg/L) were significantly lower than that in NI group (162.59 μg/L),and were significantly higher in HI1 and HI2 (2 356.27,11 507.29 μg/L) than that in NI group.The differences were statistically significant (all P ＜ 0.01).Compared with control group [(8.84 ± 2.12) μg/L],the content of serum IGF-1 increased significantly in lactation period rats in LI1 and LI2 groups [(13.30 ± 2.37) and (10.90 ± 1.92) μg/L,all P＜ 0.01].The real-time fluorescence quantification PCR detection results indicated that the differences were statistically significant by comparing NIS,AKT,PI3K mRNA expression of the mammary tissues of lactation period rats in the five groups (F=14.916,36.477,14.994,all P＜ 0.01).Among them,NIS mRNA expression quantities in LI1 and LI2 groups (0.75 ± 0.40,0.89 ± 0.51) were significantly higher than that in NI group (0.53 ± 0.31),and significantly lower in HI2 group (0.30 ± 0.24) than that in NI group (P ＜ 0.05 or ＜ 0.01).AKT mRNA expression quantities in LI1 and LI2 groups (0.90 ± 0.19,0.64 ± 0.22) were significantly higher than that in NI group (0.43 ± 0.22),and significantly lower in HI2 group (0.29 ± 0.15) than that in NI group (P ＜ 0.05 or ＜ 0.01).PI3K mRNA expression quantity in LI1 group (0.85 ± 0.42) was significantly higher than that in NI group (0.50 ± 0.24),and significantly lower in HI2 group (0.28 ± 0.10) than that in NI group (all P ＜ 0.01).Western blot detection results indicated that the differences were statistically significant by comparing mammary gland NIS protein expression of lactation period rats in the five groups (F=4.510,P＜ 0.01).Among them,LI1 group (1.67 ± 0.97) was significantly higher than NI group (0.87 ± 0.43,P ＜ 0.05).The differences were statistically significant by comparing the p-AKT protein expression among groups (F =3.528,P ＜ 0.05).Among them,HI2 group (1.10 ± 0.30) was significantly higher than NI group (0.75 ± 0.23,P ＜0.05).The differences were not statistically significant by comparing total AKT and PI3K protein expression among groups (F =0.558,1.319,all P ＞ 0.05).Conclusion The inhibitory effect of PI3K-AKT signaling pathways on NIS in the mammary gland was weaker than the effect of iodine intake.But the expression of functional p-AKT was gradually increased with the increment of iodine intake,which had been presented inhibit effect on NIS expression in lactating mammary gland.
