Objective To observe and discuss the effect of the traditional Chinese drug complex prescription ShensuⅡfrom Xintong Changluo therapeutic principle on renal interstitial fibrosis (RIF) and transforming growth factor-β1 (TGF-β1) expresssion in focal segmental glomerulosclerosis (FSGS) model rats. Methods Forty-eight healthy male SD rats were randomly divided into control group (n=12) and modeling group (n=36). Rats of modeling group were injected by doxorubicin hydrochoride for FSGS model. Rats of modeling group were sub-divided into model group, benazepril group and TCM group randomly. In 12 weeks, TCM group was given by intragastric administration of ShensuⅡ(3.5 g/100 g), benazepril group was given by intragastric administration of benazepril suspension (0.33 mg/100 g), control group and model group were given by intragastric administration of same volume of saline. HE/Masson staining was used to observe changes of tubulointerstitial pathomorphology. The degree of injury and fibrosis was measured. The expressions of fibronectin (FN) and TGF-β1 were detected by immunohistochemical SP method. Results The process of renal interstitial fibrosis was slower in FSGS rats of TCM group. Renal interstitial pathological index was 1.51 ± 0.80 in TCM group, which was lower than that of model group (2.18 ± 0.38) and benazepril group (1.79 ± 0.24). The index of renal interstitial fibrosis was 2.39 ± 0.13 in TCM group, which was lower than that of model group (3.11 ± 0.25) and benazepril group (2.80 ± 0.41). The relative expression of FN in renal interstitial was 14.19 ± 3.06 in TCM group, which was lower than that of model group (21.25 ± 3.31) and benazepril group (18.51±2.29). The relative expression of TGF-β1 in renal interstitial was 2.64±0.21 in TCM group, which was lower than that of model group (6.02 ± 0.12) and benazepril group (3.79 ± 0.46). All the differences were statistically significant (P<0.05). Conclusion Xintong Changluo complex prescription ShensuⅡcan reduce the process of renal interstitial fibrosis in FSGS model rats, which may be related with the inhibiting expression of TGF-β1.

Objective To identify the effect of health risk behaviors on accidental injury of adoles-cents.Then analyze the strength and approach of the health risk behaviors. Methods Cluster sampling on various stages and strata methods was adopted. The adolescents from grade one to three in junior school students and grade one to three in senior high school students completed the questionaire. A total of 4408 students were surveyed and 4309 samples were valid. Path analysis was used to understand how factors could influence injury incidence. Results The incidence of adolescent injury was 15.53%. Statistical differences were found between genders (male 17.77%,female 13.36%,χ2=15.91, P<0.01),education levels (junior high school 17.36%,senior high school 13.99%,χ2=11.45, P<0.01) and cities ( Beijing 12.97%,Zhongs-han 17.95%,χ2=20.33, P<0.01) . Those who got injured were found with more health risk behaviors. Health risk behavior was the direct influencing factor to injury,as well as a possible risk factor to multiple injuries. Conclusion Health risk behaviors can strongly affect adolescent injury,and can be an indicator. Reducing health risk behaviors is important in adolescent injury prevention.

Objective: Recent researches suggest that tumors are organized in a hierarchy of heterogeneous cell populations and that the capability of maintaining tumor formation/growth specifically resides in a small population of cells called cancer stem cells(CSCs).CSCs are resistant to traditional cancer chemotherapy and radiation therapy because they highly express ATP-binding cassette(ABC) drug transporters and are relatively quiescent,with higher DNA repair and anti-apoptosis abilities.The purpose of this study is to investigate the relationship of ABC transporters with the multi-drug resistance and cancer stem cells of SPC-A1 cell lines.Methods: On the basis of Docetaxel-resistant cell line-SPC-A1/ Docetaxel,we compared the content and biological characteristics of SP cells,the expression of ABC transporters and its effect on the multi-resistance to Docetaxel between SPC-A1 and SPC-A1/ Docetaxel cell lines.Results: SP cells existed in both the SPC-A1 and the SPC-A1/ Docetaxel cell line,with a higher content in the latter.P-gp and BCRP obviously expressed in the SPC-A1/ Docetaxel and SPC-A1/ Docetaxel-SP cells,but only the expression of BCRP was increased in SPC-A1-SP cells.SPC-A1-SP cells also showed obviously higher abilities of proliferation,cloning and tumor formation than SPC-A1/ Docetaxel-SP cells.The multi-drug resistance of SPC-A1/ Docetaxel cells could be reversed with verapamil,but their resistance to Docetaxel could not be reversed completely with the same concentration of the drug.Conclusion: BCRP plays a major role in separating SP cells with tumor stem cell traits and its expression counts for the multi-drug resistance of SPC-A1-SP cells.

Objective:To evaluate the effect of health education project on prevention and control of endemic diseases in Henan Province.Methods:According to the distribution and condition of endemic diseases in Henan Province, from 2008 to 2015, five project counties (cities, districts, referred to as counties) were selected in each provincial city. Three townships (towns) were selected from each project county as project townships (towns), and one central primary school and the village where the school was located were selected from each township (town) as health education survey sites. The prospective study method was adopted. Firstly, the students in the primary school of the project township (town) and the housewives in the project village were investigated with questionnaire. The intervention activities of health education were carried out in the county, township (town), village and school of the project. The intervention effect of health education was evaluated by questionnaire survey two months later.Results:There were 111 870 people investigated in Henan Province, including 74 580 students and 37 290 housewives. A total of 99 671 people were surveyed after the intervention, including 66 249 students and 33 422 housewives. Elementary student's awareness rate of endemic diseases prevention and control knowledge increased from 59.74% before intervention to 92.89% after intervention, the housewives' awareness rate increased from 65.62% before intervention to 91.82% after intervention. The awareness rate of the target population increased from 61.70% before intervention to 92.53% after intervention ( P < 0.01); among them, the awareness rates of iodine deficiency disorders, drinking water type fluorosis, coal-burning type fluorosis, drinking water type arsenic poisoning, Kashin-Beck disease and Keshan disease were significantly increased ( P < 0.01). Conclusion:With the implementation of health education project, the awareness rate of knowledge on endemic diseases has increased distinctly.

Objective: To explore the potential mechanism of acupuncture and moxibustion in treating Crohn disease (CD) by evaluating the changes in histamine and inflammatory factors in the skin tissue at Tianshu (ST25) of rats.Methods: Fifty-eight Sprague-Dawley rats were randomly divided into a normal group (n=14) and a CD-modeling group (n=44). Rats in the CD-modeling group received enema with 2,4,6-trinitrobenzene sulfonic acid plus ethanol to establish CD models. The enema was repeated once every 7 d for a total of 4 times. After modeling, four modeled rats and four normal rats were randomly selected for model identification. After the CD model was successfully established, the remaining rats in the CD-modeling group were randomly divided into a model group, an acupuncture group, a moxibustion group, and a Western medication group, with ten rats in each group. The rats in the acupuncture and moxibustion groups were treated with acupuncture or moxibustion at Tianshu (ST25) and Shangjuxu (ST37); the rats in the Western medication group were treated with mesalazine enteric-coated tablets by gavage for continuous 7 d. After the intervention, the colon tissue of rats in each group was collected. After gross observation, hematoxylin-eosin (HE) staining was performed to further observe the pathological changes. The expression of histamine in the skin tissue at Tianshu (ST25) was detected by enzyme-linked immunosorbent assay. The expression of tumor necrosis factor (TNF)-α, interleukin (IL)-1β, IL-18, IL-10, and IL-6 in the skin tissue at Tianshu (ST25) was detected by Western blotting. Results: Compared with the normal group, the colonic wall of rats in the model group showed cobblestone-like changes, local ulcers, and polyps in dark red and thickening and hardening. HE staining showed local loss of mucosal epithelial layer and formation of slit-like ulcers, destruction of mucosal glands, edema, and infiltration of inflammatory cells in lamina propria and submucosa, and occasional formation of sarcoid-like granuloma. The levels of histamine and IL-6 were significantly up-regulated (P<0.01, P<0.05), and the levels of TNF-α, IL-18, and IL-10 were significantly down- regulated (P<0.01 or P<0.05) in the skin tissue at Tianshu (ST25) of rats in the model group. Compared with the model group, the pathomorphological damage of the colon tissue of rats in the acupuncture group, moxibustion group, and Western medication group was significantly improved. The levels of histamine and IL-6 were significantly down- regulated (P<0.01, P<0.05), and the level of IL-10 was significantly up-regulated (P<0.01) in the skin at Tianshu (ST25) of rats in the acupuncture group. The levels of histamine and IL-6 were significantly down-regulated (P<0.01, P<0.05), and the levels of TNF-α, IL-18, and IL-10 were significantly up-regulated (P<0.01 or P<0.05) in the skin tissue at Tianshu (ST25) of rats in the moxibustion group. The level of histamine was significantly down-regulated (P<0.01), and the levels of IL-18 and IL-10 were significantly up-regulated (P<0.05, P<0.01) in the skin tissue of rats in the Western medication group. Compared with the acupuncture group, the level of IL-10 in the skin tissue at Tianshu (ST25) of rats in the moxibustion group was significantly up-regulated (P<0.01). Conclusion: The inflammatory responses in the skin tissue at Tianshu (ST25) may be the external manifestation of CD. Significant differences in the regulation of inflammatory responses in the skin tissue at Tianshu (ST25) between acupuncture and moxibustion exist, which may be caused by the differences in the stimulation characteristics between acupuncture and moxibustion.

Objective:To observe the effects of acupuncture and moxibustion at Feishu(BL13)on inflammatory responses and intestinal short-chain fatty acids(SCFAs)in rats with asthma. Methods:Fifty-six Sprague-Dawley rats were randomly divided into a normal group(16 rats)and a modeling group(40 rats).Rats in the modeling group were subjected to establishing asthma models using ovalbumin(OVA).Model evaluation was conducted using 4 rats from each group.The remaining rats that successfully developed asthma were then randomly divided into a model group,an acupuncture group,and a moxibustion group,with 12 rats in each group.Rats in the acupuncture group received acupuncture treatments,and those in the moxibustion group received moxibustion treatments,both at Feishu(BL13)for 30 min.Following the treatments,the rats were exposed to atomization excitation with a 1%OVA solution for 20 min daily for 14 consecutive days.At the end of the experiment,inflammatory markers in the rats'peripheral blood were analyzed using a biochemical method.In addition,inflammatory cells in the bronchoalveolar lavage fluid(BALF)were counted using Wright-Giemsa staining.The lung tissue of rats was examined under a light microscope after staining with hematoxylin-eosin to observe morphological or pathological changes.Furthermore,real-time fluorescence quantitative polymerase chain reaction was utilized to measure the mRNA expression of inflammatory factors in the lung tissue.Lastly,the concentration of SCFAs in the rat's feces was determined using gas chromatography-hydrogen flame ionization. Results:The levels of eosinophils(Eos),neutrophils(Neu),and lymphocytes(Lym)in the peripheral blood,as well as Eos and Neu in the BALF,and the expression of interleukin(IL)-4,IL-5,IL-13,IL-33,and thymic stromal lymphopoietin(TSLP)mRNAs in the lung tissue were all found to be significantly increased(P<0.05 or P<0.01);the lung tissue structure displayed severe injuries;the levels of acetic acid,propionic acid,isobutyric acid,butyric acid,and valeric acid in the feces decreased significantly in the model group(P<0.05 or P<0.01).Compared with the model group,the peripheral blood levels of Eos,Neu,and Lym,as well as Eos in the BALF,and the mRNA expression levels of IL-4 and IL-5 in the lung tissue decreased significantly in both the acupuncture group and the moxibustion group(P<0.05 or P<0.01).This reduction was accompanied by alleviated pathological damage in the lung tissue.Additionally,there were significant increases in the levels of acetic acid,propionic acid,isobutyric acid,and butyric acid in the feces in both the acupuncture group and the moxibustion group(P<0.05 or P<0.01).In the acupuncture group,the expression levels of Lym in the BALF and IL-13 mRNA in the lung tissue decreased significantly(P<0.05 or P<0.01).In the moxibustion group,the mRNA expression levels of IL-33 and TSLP in the lung tissue also reduced significantly(P<0.05 or P<0.01).Furthermore,the level of valeric acid in the feces increased notably in the moxibustion group(P<0.01).Compared with the acupuncture group,it was found that the mRNA levels of IL-5 and IL-13 in the lung tissue,as well as the acetic acid level in the feces,were significantly higher in the moxibustion group(P<0.05 or P<0.01). Conclusion:Both acupuncture and moxibustion were effective in reducing abnormal inflammation and regulating intestinal SCFAs in asthma model rats.Acupuncture demonstrated superiority in inhibiting pro-inflammatory factors,particularly IL-5 and IL-13,while moxibustion exhibited better regulation on intestinal metabolites SCFAs,especially acetic acid.

Objective To explore the disparity of severity of cardiac dysfunction and recovery among different glycometabolic patients in the early phase of acute myocardial infarction (AMI) . Methods Consecutive 111 AMI patients without known diabetes underwent continuous glucose monitoring. Patients with different glycometabolic status were compared in terms of cadiac dysfunction and recovery at admission and 3month follow up. Results Compared to patients with normglycemia and transient hyperglycemia, patitents with persistent hyperglycemia were more likely to grade Killip Ⅱ or above,which were 13.3% (4/30) ,33. 3% ( 12/36) ,55. 6% (25/45), 20. 0% ( 6/30), 41.7% ( 15/36 ) and 93.3% (42/45) ( Ps ＜ 0. 01 ). In-hospital left ventricular ejection fraction (LVEF), mitral valve protodiastolic E peak velocities (E) and its ratio to late diastolic (E/A) decreased significantly ( LVEF :0. 52 ± 0. 02,0. 48 ± 0. 01 and 0. 37 ± 0. 02; E: [0. 65 ± 0. 41]m/s,[0.55 ± 0.02] m/s and [0.39 ±0. 12]m/s;E/A:1. 15 ±0.08,1.02 ±0.06 and 0.61 ±0.02,respectively) ( Ps ＜ 0. 01 ), whereas LVESV and WMSI increased significantly ( LVESV: [25.83 ± 0. 51] ml,[31.26 ± 1.23] ml, [37, 72 ± 1.01] ml; WMSI: 1.5 ± 0. 3,1.8 ± 0. 2 and 2. 6 ± 0. 4, respectively) ( Ps ＜ 0. 01 )There months after AMI,patitents with persistent hyperglycemia were more likely to grade NYHA Ⅱ or above compared to patients with normglycemia and transient hyperglycemia [67.5% (27/40), 10.0% (3/30) and 11.8% (4/34),respectively] (P ＜0. 01 ). Echocardiographic recovery was observed in each group,but less in persistent hyperglycemia patients. Conclusion Cardiac function of patients with persistent hyperglycemia suffered more severely from AMI and difficult to recover.

One hundred and eleven patients with acute myocardial infarction and without known diabetes mellitus who underwent continuous glucose monitoring were divided into normoglycemia(n = 30),transient hyperglycemia(n = 36),and persistent hyperglycemia(n = 45)groups.Compared with other two groups,higher mean blood glucose,standard deviation of blood glucose,largest amplitude of glycemic excursions,mean amplitude of glycemic excursions,and absolute mean of daily differences were observed in the patients with persistent hyperglycemia group(all P<0.01),who were more likely to be female with the history of hypertension and old myocardial infarction(all P<0.05).It was shown that the levels of aspartate aminotransferase,creatine phosphokinase(CK),CK-MB,total cholesterol,triglyceride,low-density lipoprotein cholesterol,HbA1C,and C reactive protein levels were higher in these patients(P<0.01).

Objective:To compare the effects of Feishu(BL13)combined with Tianshu(ST25)and Feishu(BL13)alone on pulmonary function and tissue inflammation in asthma model rats. Methods:Forty-eight Sprague-Dawley rats were randomly divided into a normal group,a model group,a lung treatment group,and a lung-intestine treatment group according to the random number table method,with 12 rats in each group.Except for the normal group,rats in the other three groups were sensitized by ovalbumin followed by atomization stimulation to establish the asthma model.After the model was made successfully,rats in the lung treatment group were treated with acupuncture at bilateral Feishu(BL13)for 30 min;rats in the lung-intestine treatment group were treated with acupuncture at bilateral Feishu(BL13)and Tianshu(ST25)for 15 min,respectively,for 30 min in total.Acupuncture was performed once a day for 14 d.Rats in the other two groups did not receive any intervention.After intervention,the pulmonary function of each group of rats was measured by a pulmonary function tester.The histopathological changes stained by hematoxylin-eosin staining and the collagen deposition degree stained by Masson in lung tissue,as well as the inflammatory cells in the bronchoalveolar lavage fluid(BALF)stained by Wright's-Giemsa staining were observed under a light microscope;the levels of interleukin(IL)-4,IL-5,IL-13,IL-17,IL-25,IL-33,leukotrienes(LT),thymic stromal lymphopoietin(TSLP),and prostaglandin D2(PGD2)were detected by enzyme-linked immunosorbent assay. Results:Compared with the normal group,the peak expiratory flow(PEF),the dynamic lung compliance(Cdyn),the forced expiratory flow 25%(FEF25%),the forced expiratory volume in the first second/forced vital capacity(FEV1/FVC),and the maximum mid-expiratory flow(MMEF)in the model group were significantly decreased(P<0.01 or P<0.05);the lung resistance(RL),the collagen deposition,the IL-4,IL-5,IL-13,IL-17,IL-33,LT,TSLP,and PGD2 levels,and the neutrophil proportion in the BALF were increased significantly(P<0.01 or P<0.05).Compared with the model group,the FEF25%and FEV1/FVC in the pulmonary function were significantly increased(P<0.01,P<0.05),while the collagen fiber deposition and the levels of IL-4,IL-5,IL-13,IL-17,LT,TSLP,and PGD2 were significantly decreased(P<0.01 or P<0.05)in the lung treatment group;the PEF,FEF25%,and FEV1/FVC in pulmonary function were significantly increased(P<0.01 or P<0.05),while the RL and the collagen fiber deposition,as well as the neutrophil proportion and the levels of IL-4,IL-5,IL-13,IL-17,IL-33,LT,TSLP,and PGD2 in the BALF were significantly decreased(P<0.01 or P<0.05)in the lung-intestine treatment group.Compared with the lung treatment group,the IL-5 level in the rat lung tissue of the lung-intestine treatment group was decreased(P<0.05). Conclusion:Acupuncture in the lung treatment and the lung-intestine treatment groups improved pulmonary function,lung inflammation,and inflammatory cells in the BALF in asthma model rats;the lung-intestine treatment was better than lung treatment in improving the IL-5 level.The combination of Feishu(BL13)and Tianshu(ST25)was superior to Feishu(BL13)alone in the treatment of asthma in trend.

Objective:To evaluate the success rate and influencing factors of auscultation-assisted bedside blind placement of the spiral nasojejunal feeding tube in oldest-old patients.Methods:A case series study was conducted in those elderly hospitalized patients who met the indications for naso intestinal intubation from January 2019 to May 2021 in China-Japan Friendship Hospital. Auscultation-assisted bedside blind placement of the spiral nasojejunal feeding tube was implemented. In addition, abdominal X-ray imaging was performed to confirm the location of the catheter tip. The primary indicators included were the success rate and the first attempt success rate of nasojejunal tube placement;, while the secondary indicators included were the number of attempts and the time of insertion. The rate of operational-related adverse events was ustreated as to evaluate the indicator of safety. Logistic regression analysis was used to conduct multi factor analysis.Results:The total success rate and the first-attempt success rate of tube implantation reached were 90.1%(73/81) and 85.2%(69/81), respectively. The mean attempt per individual patient was (1.2 ± 0.2) times for each patient. The median length of operation time was 40.0(27.0, 45.0) minutes, more specifically, among which the median length time of nasogastric and gastrojejunal placement was 20.0(15.0, 25.0) and 18.0(12.5, 20.0) minutes, respectively; while the median lengthtime of nasogastric placement was greaterhigher than that of gastrojejunal placement ( Z = -2.78, P<0.05). As suggested by multivariate analysis, indicated that the conscious conditions of patients had a signific antlyimpact affect on the success rate of for tube implantation ( OR = 19.25, 95% CI 1.24-299.63, P<0.05). In addition, the incidence rate of operational-related adverse events was 37.0%(30/81). By contrast, there were no serious adverse events occurring during the study period. Conclusions:The auscultation-assisted bedside blind placement of the nasojejunal feeding tube technique is effective and safe for early nutrition support in oldest-old patients in terms of early nutritionsupport, the success rate of which is significant largely affected by the patients′ conscious conditions of patients.
