BACKGROUND: Although clinical methods for autologous peripheral blood stem cell separation and identification arerelatively more, there is no unified standard. Moreover, little is reported on immune effects on lung adenocarcinomaduring autologous peripheral blood stem cell transplantation.OBJECTIVE: To study the effect of autologous peripheral blood stem cell transplantation on immunological function oflung adenocarcinoma rats by exploring the separation and identification methods of autologous peripheral blood stemcells.METHODS: The mononuclear cells were isolated from the peripheral blood of Wistar rats by density gradientcentrifugation method and then identified. Eighteen Wistar rats were randomly divided into routine treatment group andcell transplantation group, with nine rats in each group. Animal models of lung adenocarcinoma were established in therats, and underwent no treatment in the routine treatment group but injection of autologous peripheral blood stem cellsuspension (0.2 mL, 2.5×106/L) via the tail vein in the cell transplantation group. Immune indicators were detected in twogroups after treatment. Three rats from each group were anesthetized and scarified at 4, 10, 14 days after treatment,respectively. Afterwards, we detected the effects of autologous peripheral blood stem cell transplantation onimmunological function of lung adenocarcinoma rats.RESULTS AND CONCLUSION: Newly isolated mononuclear cells from rat peripheral blood showed a round or ovalshape and were relatively small in size. After 5 days of culture, autologous peripheral blood stem cells grew rapidly, andthe round cells began to spread to both ends and became spindle-shaped, thereby forming small colonies. Autologousperipheral blood stem cells induced in vitro experienced three stages successively: cell arrest, logarithmic and plateauphases. Flow cytometry showed that sorted cells were identified as autologous peripheral blood stem cells by expressingCD90, CD133 and Flk-1. After 4, 10 and 14 days culture, the expression of CD133 increased first and then descended,and Flk-1 showed an increasing trend. Compared with the routine treatment group, the expression of tumor necrosisfactor-α induced protein 6 in the cell transplantation group was significantly higher (P < 0.05), while the expression ofnuclear factor κB was significantly lower (P < 0.05). In conclusion, the isolation and identification methods of autologousperipheral blood stem cells are simple and can be used to secrete a large number of nutritional factors in the treatment oflung adenocarcinoma, which can enhance body immunity in the treatment.

Objective To develop a high stability and wide coverage network with power cat technology to promote hospital informatization.Methods The common network layout methods were compared,and the advantages of power cat technology were introduced when used for network layout.A series or parallel connection method was used to lay the power cat in the existing power line,and to achieve the full coverage of the hospital network.Results Power cat technology gained advantages in high efficiency,low cost and high stability when used for network layout.Conclusion A stable,economic and convenient network is constructed in the hospital with power cat technology.

Objective To investigate the prevalence of orthostatic hypotension in hypertensive patients aged 80 or over and associated risk factors at level A tertiary hospitals.Methods A multicenter cross-sectional study was conducted among very old hypertensive patients (≥ 80 years) at 28level A tertiary hospitals by using questionnaire-based surveys.A total of 1298 hypertensive subjects aged between 80 and 101 years were enrolled in this study.Blood pressures was measured in the supine position and the upright position within three minutes of standing,and 316 patients were assigned to the orthostatic hypotension(OH) group and the other 982 patients to the non-orthostatic hypotension(NOH) group.Additional information was acquired through patients' medical records and the questionnaire.Results The prevalence of OH was 24.3％ (316 cases) There were no significan different betueen OH patienl with NOHones in gender and age.OH patients had higher supine systolic and diastolic blood pressure(P=0.003 and 0.000,respectively),lower standing systolic and diastolic blood pressure(P=0.000 and 0.000,respectively),and higher rates of past coronary heart disease,stroke and renal abnormalities (P =0.037,0.001 and 0.014,respectively) than NOH patients.Logistic regression analysis showed that the prevalence of OH in the patients was positively correlated with supine systolic blood pressure(OR=1.196,CI:1.153-1.242,P=0.000) and supine diastolic blood pressure (OR =1.740,CI:1.602-1.885,P =0.000) and was negatively correlated with standing systolic blood pressure(OR =0.824,CI:0.795-0.855,P=0.000) and standing diastolic blood pressure (OR =0.584,CI:0.539-0.634,P =0.000).Conclusions The prevalence of orthostatic hypotension is high in hypertensive patients aged 80 years or over at level A tertiary hospitals.Poor blood pressure control may increase the risk of orthostatic hypotension.

Objective To observe the effects of anti depression therapy on post stroke and neurological rehabilitation in the elderly. Methods There were 178 post stroke depression (PSD) cases. They were divided into 3 groups: 64 cases taking Prozac once every morning about 20 80 mg daily; 58 cases taking amitriptyline twice everyday about 50 100 mg daily and 56 cases taking placebo as control group. All of them were on the regular treatment of cerebrovascular disease. All the cases were evaluated according to the HAMD score, neurological function impairment and ADL before treatment and 1 st , 2 nd , 4 th , 8 th week and 3 rd , 6 th , 12 th month after the treatment. Results At the 2 nd week, HAMD score dropped obviously from 27 7?6 9 to 17 3?5 9 in Prozac group, from 26 9? 6 9 to 15 7?4 2 in amitriptyline group, with significant difference vs pre treatment and the control groups ( P

OBJECTIVE To observe therapeutic efficacy and safety of transcatheter arterial chemoembolization (TACE) com-bined with high intensity focused ultrasound (HIFU) in the treatment of middle and advanced primary hepatocellular carcinoma (HCC). METHODS:76 patients with middle and advanced primary HCC were randomly divided into treatment group(36 cases) and control group(40 cases). Control group was given TACE alone,and treatment group was additionally given HIFU 2-3 weeks after TACE. Clinical efficacy,the content of alpha-fetoprotein(AFP)before and after operation,survival rate,survival period and ADR were compared between 2 groups. RESULTS:The efficiency rate and total effective rate of treatment group were 61.1% and 94.4%,which were significantly higher than those of control group(35.0%,77.5%),with statistical significance(P<0.05). The content of AFP in 2 groups decreased significantly after operation,with statistical significance(P<0.05);there also was statistical significance between 2 groups(P<0.05). Survival rate of treatment group was higher than that of control group 24 and 36 months after operation,with statistical significance (P<0.05). The median survival time was 11.3 months in treatment group and 9.2 month in control group,with no statistical difference(P>0.05). No obvious ADR was found in 2 groups. CONCLUSIONS:Com-pared with TACE alone,TACE combined with HIFU in the treatment of middle and advanced primary HCC can improve long-term survival rate and the short-term efficacy,with good safety.
