Objective To observe the clinical efficacy of scraping therapy plus Yi Yi Ren (Semen Coicis) congee in treating functional dyspepsia due to dampness-heat blocking the stomach. Method Sixty-four patients were divided into an observation group and a control group by using the random number table, 32 cases in each group. The observation group was intervened by scraping therapy plus Yi Yi Ren (Semen Coicis) congee, while the control group was by Mosapride citrate dispersible tablets. The two groups were both treated for 4 weeks. The traditional Chinese medicine (TCM) symptom score, Nepean Dyspepsia Symptom Index (NDSI), and Nepean Dyspepsia Life Quality Index (NDLQI) were observed before and after the intervention and the clinical efficacy was evaluated, for comparison and analysis. Result The total effective rate was respectively 93.8%in the observation group and 78.1%in the control group, and the observation group was superior to the control group (P<0.05);after the intervention, the TCM symptom scores and NDSI scores dropped significantly in the two groups (P<0.05,P<0.01), and the NDLQI scores increased significantly in the two groups (P<0.05), and the improvements in the observation group were more significant (P<0.05). Conclusion Scraping therapy plus Yi Yi Ren (Semen Coicis) congee and Mosapride citrate dispersible tablets are both effective in treating functional dyspepsia due to dampness-heat blocking the stomach, while the former one can produce a more significant therapeutic efficacy and improve the symptoms and quality of life in a better way.

BACKGROUND: Skeletal muscle satellite cells are muscle-derived stem cells with proliferation and differentiation potential. Recently, foreign researches have reported that skeletal muscle satellite cells can be activated by some definite microenvironmental factors and differentiate into hematopoietic stem cells and thereby they will have the potential of hematopoietic reconstruction.OBJECTIVE: To initially validate the potential of adult muscle-derived stem cells- skeletal muscle satellite cells differentiating into hematopoietic stem cells.DESIGN: Validation animal experiment.SETTING: Department of Histology and Embryology, College of Basic Medical Science, Tianjin University of Traditional Chinese Medicine.MATERIALS: Sixty-five male Kunming adult mice, weighing 25-28 g, were involved in this study. Five Kunming neonate rats, aged 5 days, were provided by the Laboratory Animal Center, Department of Medicine, Peking University.METHODS: This experiment was carried out in the Laboratory for Cell Culture, Department of Human Anatomy and Histo-embryology, School of Basic Medical Sciences, Peking University Health Science Center between August 2001 and August 2003. Skeletal muscle satellite cells of 5 neonate rats were isolated by collagenase and trypsin digestion. Bone marrow mononuclear cells of 5 adult Kunming mice were isolated. Sixty adult female mice were used as recipients, irradiated with 60Coγ 8.0 Gy and then randomized into 4 groups: control group, in which, the mice were untouched; culture fluid infusion group, in which, the mice were injected with DMEM/F-12 medium through caudal vein; satellite cell infusion group, in which, the mice were injected with 0.3 mL satellite cell suspension through caudal vein (cell concentration 1×109 L-1); bone marrow-derived cell infusion group, in which, the mice were injected with 0.3 mL bone marrow-derived cell suspension (cell concentration 1×109 L-1) through caudal vein.MAIN OUTCOME MEASURES:①The survival rate of 14-day-old mice in each group. ②The surviving recipient mice were euthanized 14 days after irradiation, and tubercles on the surface of spleen were counted by naked observation; Bone marrow mononuclear cell smear was stained by Wright-Gimesa.RESULTS:① Determination of colony forming unit-spleen (CFU-S): No significant difference in the number of spleen tubercles of mice existed between satellite cell infusion group and bone marrow-derived cell infusion group 14 days after irradiation (P＞0.05). ②Histological identification of bone marrow-derived mononuclear cells: Many hematopoietic cells appeared at the early stage in the bone marrow-derived mononuclear cell smears between satellite cell infusion group and bone marrow-derived cell infusion group. Their morphology meets the biological characteristics of hematopoietic cells at the early stage. ③ The survival condition of irradiated mice: All the mice in the control group and culture fluid infusion group died 9 to 13 days after irradiation. In contrast, 8 mice from the satellite cell infusion group and 13 the bone marrow-derived cell infusion group survived 14 days after irradiation.CONCLUSION: Skeletal muscle satellite cells have the function of differentiating into hematopoietic stem cells.

Objective To evaluate the clinical results of femoral-deep femoral crossover bypass in the treatment of long-segment unilateral iliac artery occlusive disease.Methods From July 1995 to December 2010,40 patients (28 males,12 females,aged from 66 to 90,with mean age of 73) with comprehensive unilateral iliac-superficial femoral arteriosclerosis obliterans were enrolled in this procedure.All patients suffered from unilateral common iliac,external iliac,common femoral,and superficial femoral arteriosclerosis obliterans.These patients were treated with femoral-deep femoral crossover bypass.Postoperative ankle-brachial index,blood flow velocity and patency rates in 5,7 and 10 years and limb salvage rates in 5,7 and 10 years were evaluated.Results There was no perioperative mortality nor extremity amputation.35 (87.5％ ) patients were followed-up from 1 to 13 years (mean 5.7 y).Anklebrachial index rose from preoperative 0.23 ± 0.10 to postoperative 0.55 ± 0.11 (t =15.91,P =0.000 ).Popliteal arterial velocity rose from preoperative ( 14 ±6) cm/s to postoperative (34 ± 10) cm/s (t =15.63,P =0.000) ; Tibial arterial velocity rose from ( 10 ±4) cm/s to (22 ±7) cm/s (t =15.71,P =0.000).The primary and secondary patency rates were 60.1％,44.3％,25.3％,and 93.5％,86.8％,57.9％ at 5,7 and 10 years,respectively.Limb salvage rates were 97.5％,95％,and 90％,at 5,7 and 10 years,respectively.Conclusions Femoral-deep femoral crossover bypass is safe and reliable in treating certain unilateral iliofemoral occlusive disease,especially for high-risk old patients or those who are not indicated for endovascular therapies or direct aortic approaches.

Objective To study the influence of long-term home noninvasive positive pressure ventilation (HNPPV) on respiratory muscle strength in patients with stable severe chronic obstructive pulmonary disease (COPD).Methods Sixty-four patients with stable severe COPD discharged from Huabei Oil-field Hospital,Renqiu,Hebei were divided into two groups,one (n=24) with HNPPV plus conventional therapy,and the other (n=40) with conventional therapy plus long-term oxygen therapy as controls.All parameters were followed-up for one-year and compared for the two groups,including maximal iuspiratory pressure (MIP),transdiaphragmatic pressure (Pdi),maximal transdiaphragmatic pressure (Pdimax),ratio of Pdi/Pdimax,arterial partial pressure of carbon dioxide (PaCO2),forced expiratory volume in one second (FEV1),6-min walking distance (6MWD),mortality and re-hospitalization rate.Results Age,gender,course of the disease,body mass index (BMI),arterial PaCO2,PaO2,MIP,Pdi,Pdiraax,ratio of Pdi/ Pdimax,FEV1,ratio of FEV1/FVC%,6MWD and re-hospitalization rate of the patients between the two groups were all comparable (P>0.05).In one-year follow-up,PaCO2averaged (52±8)mm Hg,MIP (64±7) cm H2O,Pdi (33±5) cm H2O,Pdimax (101±9) cm H2O,Pdi/Pdimax (0.31±0.04),FEV1 (35±4) %,FEV1/FVC% (44±4) %,6MWD (272±26) m and (2.6 ± 0.8) admissions per year in the HNPPV group,significantly different from those in the control group [ (57 ± 6) mm Hg,(59 ± 6) cm H2O,(31±4) cm H2O,(84±7) cm H2O,(0.35±0.05),(33±3)%,(41±4)%,(212±28) m,and (3.7±0.8) admissions per year] (P<0.05).One death was observed in the HNPPV group (1/24) and three in the control group (3/4 0) in one - year follow - up,with no statistically significant difference (X2=0.00,P>0.05).Conclusions Long-term use of HNPPV for patients with stable severe COPD could efficiently improve their respiratory muscle strength and endurance,thus improving their pulmonary ventilation and treatment efficcacy.

Objective:To identify the effects of Xuefu Zhuyu Capsule (XZC) on the surgical treatment of patients with chronic subdural hematoma (CSDH).Methods:Retrospectively collected 96 pairs of patients who undergoing burr-hole craniotomy (BHC) for CSDH from January 2016 to December 2019 in Dalian Municipal Central Hospital. Clinical characteristics and imaging information of each patient were extracted, the follow-up period was six months. Differences in demographics and postoperative outcomes were compared between BHC+XZC group and BHC only group. Univariate analysis and multivariate analysis with Logistic regression model were performed to determine independent associations among the various probable effective factor. The relationship between related factors and effectiveness of CSDH was estimated with odds ratio ( OR) and 95% CI. Results:Effectiveness in 87 cases (90.6%) patients with surgery and received XZC postoperatively was significantly higher than 76 cases (79.2%) patients who underwent surgery alone. Multivariate Logistic regression analysis showed postoperative administration of XZC and preoperative Glasgow coma scale (GCS) score were independent protective factors for CSDH to improve therapeutic effect.Conclusions:This study suggested postoperative administration of XZC for CSDH patients can improve the therapeutic effect, a higher preoperative GCS score is contributed to the postoperative effect.
