Allogeneic hematopoietic stem cell transplantation is the only measure which can cure multiple myeloma,but the high mortality rate related with it limited its use.Autologous hematopoietic stem cell transplantation(Auto-HSCT) has made a great contribution at improving the patients' quality of life and prolonging the survival.In recent years,the application of new drugs and new chemotherapy regimen consisted of traditional chemotherapy and new drugs further enhance the curative effect.

The present experiment was to study the hematopoietic reconstruction effects of peripheral blood stem cell (PBSC) mobilized by anti-CD49d monoclonal antibody (McAb) and recombinant human granulocyte colony-stimulating factor(rhG-CSF) in mice. PBSCs from NS-treated mice (control group), rhG-CSF-mobilized mice (experimental group1), and anti-CD49d McAb-mobilized mice (experimental group 2), The changes in respectively, were transplanted to BALB/c mice pre-conditioned with high-dose chemotherapy and total body irradiation white blood cell (WBC) count, four-weeks survival rate, bone marrow nuclear cells (BMNC), granulocyte-macrophage colony-forming units (CFU-GM), and colony-forming unit-spleen (CFU-S) were observed. The results showed that survival rate, WBC, BMNC, CFU-GM, and CFU-S counts were significantly higher in experimental groups 1 and 2 than those of the control group(P

Objective The study aimed to know the mental health state of juvenile delinquents, to provide basis for the early prevention of juvenile delinquency and the rectification of the unhealthy mental state. Methods The 378 juvenile delinquents from Tianjin reformatory were deem to the study group, the 410 14~18 years old high school students were sampled from a common school as the control group. They were assessed and compared with SCL-90. Result The indices of SCL-90 excluding somatic change, interpersonal relationship were higher than that of the domestic routine model (P

Objective To evaluate the effect of single injection of low dose zoledronic acid on bone resorption.Methods332 menopausal patients with bone deficiency treated in our hospital were selected.The patients were treated with zoledronic acid 1mg (1mg group), 2.5mg treatment group (2.5mg group), 5mg treatment group (5 mg group) and placebo treatment group (control group), each group of 83 patients.The patients of 1mg group, 2.5mg group and 5 mg group were treated with 1mg, 2.5mg and 5mg zoledronic acid alone.The patients in the control group were given intravenous infusion of placebo.Evaluated the lumbar spine (L1-L4) and total hip bone mineral density (BMD) and bone metabolic markers at baseline, 6, 12, 18, and 24 months in the four groups.The bone metabolic criteria included t β-Cterminal-telopeptide of type I collagen (β-CTX) and procollagen type-I N-terminal propeptide (P1NP).ResultsThe Lumbar spine BMD and the Total hip BMD were significantly higher in 1mg group than baseline value and Simultaneous valueand in the control group (P<0.05), The difference were statistically significant (all P<0.05).The values at 8 and 24 months decreased gradually.The value was significantly lower (P<0.05) compared with the control group, There were no statistically significant difference compared with the simultaneous value in control group.The lumbar BMD and the total hip BMD in 2.5mg and 5mg groups were significantly lower than the baseline values during the whole trial period (all P<0.05).The trend of β-CTX and P1NP was similar to that of BMD in each group.ConclusionIntravenous injection of 1 mg and 2.5 mg of zoledronic acid produces anti-bone resorption that can last for at least 1 year.After one year of treatment, The effect of single injection of 2.5 mg of zoledronic acid on bone is similar to that of single injection of 5 mg zoledronic acid.1 mg zoledronic acid produced by anti-bone resorption can last for 12 months, and then slowly disappear.

Objective To evaluate the diagnostic and therapeutic status of lower urinary tract symptoms(LUTS)/benign prostatic hyperplasia (BPH) (LUTS/BPH) in outpatient department for elderly patients, and to understand the patients' attitude and knowledge on the disease. Methods The investigation was conducted in 34 outpatient departments for elderly patients located in 11 cities from February to September 2008. The male patients who came to the clinic during the survey time were investigated whether they had LUTS /BPH history or not. Then some eligible patients were chosen to accept a more detailed questionnaire and BPH-related examinations. Results There were 31371 male patients who came to the clinic. 47.0% of them (14748 cases) had the history of LUTS / BPH, and 72.4 % (10678 cases) had medical or surgical treatments presently or previously, whereas 27.6% were untreated. The three most commonly performed examinations in clinical practice were urinalysis, prostate specific antigen (PSA) and transabdominal ultrasonography. In 3542 patients receiving medical investigation, 32.6% (1155 cases) were given 5a reductase inhibitor, and 35.0% (1239 cases) received a combination therapy of 5a reductase inhibitor plus a receptor blocker. 84.5 (1796 cases) and 79.0% (1678 cases) of all the patients were satisfied with the examinations and treatments respectively. Conclusions LUTS and BPH are common in outpatient department for elderly patients. There are discrepancies of examinations and medical treatments between real medical practice and international suggestion, and the patients' understanding of the disease should be improved

Objective To realize and analyze the current status of medical treatment for benign prostatic hyperplasia in special clinic for elderly in China.Methods The informations were gathered from 34 clinics for elderly located in 11 Chinese cities from February 2008 to September 2008.First, all male patients who visited the clinic were inquired about their history of benign prostatic hyperplasia , and then 1000 benign prostatic hyperplasia patients who were receiving medical treatment were selected to finish a detailed questionnaire and to get several examinations for benign prostatic hyperplasia.Results Among the 1000 patients, 774 completely finished the questionnaire, patients with middle or severe international prostate symptom score (IPSS) and with high volume of prostate occupied a large proportion.Medical treatments included the combined therapy of α-blockers plus 5α reductase inhibitors (45.48 %), α-blockers (36.30%), 5α reductase inhibitors (13.05 %) and other medicines (including phytotherapeutic agents and traditional medicines, 5.17%).Conclusions Nowadays in China, as to the prescription for benign prostatic hyperplasia in the clinic for elderly presents, doctors only concentrate on the improvement of symptoms, whereas ignore the progression of the disease.There is still a considerable gap between real medical treatment and international guidelines.Therefore, improvements of medical treatment are still needed in the future clinical practice.

Objective To evaluate the demands of patients with benign prostatic hyperplasia (BPH) and its influencing factors. Methods One thousand five hundred and twenty-seven patients (≥60 years old) with BPH in 26 hospitals of 9 cities were selected in the study by using stratified random sampling method. The demands of patients with BPH and its influencing factors were evaluated by rank sum test and rank correlation analysis. Results In 1527 BPH patients, most patients thought that doctors' communication with them before opening examination items (1297/ 1527,84.9%),health guidance for BPH progress(1310/1527,85.8%), BPH diagnosis(1279/1527, 83.8 %) and BPH treatment(1329/1527,87. 0%) were necessary. Doctors'communication with them before opening examination items, health guidance for BPH progress, BPH diagnosis and BPH treatment showed significant statistical difference among patients with different age, medical care, the lasting time of clinical symptoms, diagnosis time, international prostate symptom scores and quality of life scores (all P<0. 05). While in patients with different nation, retirement status, marital status, living style and average family income, there were no significant statistical difference in needing the doctors'communication with them before opening examination items, health guidance for BPH progress, BPH diagnosis and BPH treatment(all P>0.05). Conclusions Patients with BPH have a higher demand for treatment. The demand degree is related with age group, health care, the lasting time of clinical symptoms, diagnosis time, international prostate symptom scores and quality of life scores. Most patients have desire to accept health guidance.

PURPOSE: The degradation of the extracellular matrix has been shown to play an important role in the treatment of hepatic cirrhosis. In this study, the effect of thalidomide on the degradation of extracellular matrix was evaluated in a rat model of hepatic cirrhosis. MATERIALS AND METHODS: Cirrhosis was induced in Wistar rats by intraperitoneal injection of carbon tetrachloride (CCl4) three times weekly for 8 weeks. Then CCl4 was discontinued and thalidomide (100 mg/kg) or its vehicle was administered daily by gavage for 6 weeks. Serum hyaluronic acid, laminin, procollagen type III, and collagen type IV were examined by using a radioimmunoassay. Matrix metalloproteinase-13 (MMP-13), tissue inhibitor of metalloproteinase-1 (TIMP-1), and alpha-smooth muscle actin (alpha-SMA) protein in the liver, transforming growth factor beta1 (TGF-beta1) protein in cytoplasm by using immunohistochemistry and Western blot analysis, and MMP-13, TIMP-1, and TGF-beta1 mRNA levels in the liver were studied using reverse transcriptase polymerase chain reaction. RESULTS: Liver histopathology was significantly better in rats given thalidomide than in the untreated model group. The levels of TIMP-1 and TGF-beta1 mRNA and protein expressions were decreased significantly and MMP-13 mRNA and protein in the liver were significantly elevated in the thalidomide-treated group. CONCLUSION: Thalidomide may exert its effects on the regulation of MMP-13 and TIMP-1 via inhibition of the TGF-beta1 signaling pathway, which enhances the degradation of extracellular matrix and accelerates the regression of hepatic cirrhosis in rats.

Objective? To explore the current situation of health empowerment of elderly fragility fracture patients and to analyze its influencing factors. Methods? We selected four Class Ⅲ Grade A hospitals randomly in Hengyang. From October 2017 to February 2018, a total of 176 elderly fragility fracture inpatients were investigated with the self-designed general information questionnaire, Elderly Frailty Assessment Scale, Osteoporosis Self-Efficacy Scale (OSES), Health Empowerment Scale for Elderly Patients with Chronic Disease. Multiple linear regression analysis was used to explore the influencing factors of health empowerment of patients. Results? The score of health empowerment of elderly fragility fracture patients was (89.00±14.31) and responsibility belief dimension was with the highest score (3.74±0.88). Patients' health empowerment had a negative correlation with the frailty (r=-0.576, P＜0.01) and had a positive correlation with the self-efficacy (r=0.496, P＜ 0.01). Multiple linear regression analysis showed that the main influencing factors of health empowerment of patients included ages, education levels, medical payment methods, frailty and self-efficacy (P＜0.05). Conclusions? Nurses should pay attention to patients' health empowerment ability and provide the individualized nursing to strengthen the health empowerment ability of elderly fragility fracture patients.

OBJECTIVETo detect the expression of cytokines by acute promyelocytic leukemia (APL) cells before and after exposure to arsenic trioxide.

METHODSDiagnoses were performed according to the FAB cytological classification criteria and cytogenetic criteria. Bone marrow or blood samples from APL patients were collected in heparinized tubes, then primary APL cells were separated by traditional Ficoll-Hypaque density centrifugation and purified after adherence to plastic surfaces. IL-1(beta), IL-6, IL-8, TNF alpha and G-CSF levels in the leukemia cell culture supernatants were detected by ELISA. At the same time, nitro blue tetrazolium (NBT) reduction test was used to detect the differentiation of APL cells.

RESULTSAfter 96 hours exposure to arsenic trioxide, 10 - 6 mol/L in vitro or 10 mg/d in vivo, APL cells showed a significant increase of IL-1(beta) (P < 0.05) and G-CSF (P < 0.05) production, and a significant decrease of IL-6 (P < 0.05) and IL-8 (P < 0.05). However, there was no obvious variation of TNF alpha when compared with APL cells without exposure to arsenic trioxide. On the other hand, the proliferation ratio of APL cells in vitro was statistically correlated to the IL-1(beta) secretion ratio or G-CSF secretion ratio. The cell number ratio in patients with detectable IL-1(beta) or G-CSF was higher than that without detectable IL-1(beta) or G-CSF.

CONCLUSIONIL-1(beta) and G-CSF secretion may play an important role in the proliferation of APL cells after exposure to arsenic trioxide.
