OBJECTIVE:To investigate the effects of Danhong injection combined with low molecular weight heparin (LM-WH) on clinical symptoms,serum inflammatory factors and lung function in elderly patients with chronic obstructive pulmonary disease (COPD). METHODS:A total of 146 elderly patients with COPD were randomly divided into observation group and con-trol group,with 73 cases in each group. Both groups received conventional treatment. On this basis,control group was given Dan-hong injection 30 mL,intravenous drip,once a day. Observation group was additionally given LMWH sodium injection 5000 IU, subcutaneously,twice a day,on the basis of control group. Both groups were treated for 14 d. Clinical efficacies of 2 groups were observed and compared. The clinical symptom score,the levels of IL-6,IL-8,TNF-α,FEV1,FEV1/FVC,pa(O2),pa(CO2) and the occurrence of ADR were compared before and after treatment. RESULTS:After treatment,the total response rate of observa-tion group was significantly higher than that of control group(93.15%vs. 78.08%,P<0.05). Before treatment,there was no statis-tical significance between above indexes (P>0.05). After treatment,individual clinical symptom score,total clinical symptom score,the levels of IL-6,IL-8,TNF-α,pa(CO2)in 2 groups were significantly lower than before;the observation group was signif-icantly lower than the control group;FEV1,FEVl/FVC,pa(O2) were significantly higher than before,and the observation group was significantly higher than the control group,with statistical significance (P<0.05). CONCLUSIONS:Based on conventional treatment,Danhong injection combined with LMWH is effective in the treatment of senile COPD,and can significantly improve the clinical symptoms,serum inflammatory factors levels and pulmonary function with good safety.

The occurrence rate of DTC in children and adolescents is not high.However,DTC in these patients has some distinct characteristics different from those in adult,such as larger tumor volume at diagnosis,early invasion of neck lymph nodes and early distant metastases,high NIS expression,high recurrence but higher overall survival rate.131 I ablation is still one of the important treatment methods after surgery.Currently,there are 3 major dosage regimens adopted for 131I treatment: prescribed dose without causing bone marrow suppression/toxicity,dose aiming at tumor ablation,and empirically fixed dose.

BACKGROUND:Thoracic vertebrae connected with the ribs of corresponding segments constitute the thorax. Because of thoracic vertebrae deeply and complicated structure, it is difficult to operate or to expose thoracic vertebrae completely. The traditional anterior ways can thoroughly remove the focus and achieve a good internal fixation, but this treatment needs to cut the rid. The surgeon discovered in years of clinical practice that distraction of intercostal space without cutting off the ribs could completely remove the focus and achieve fixation and fusion. OBJECTIVE:To explore the feasibility, advantages and disadvantages of anterior plate fixation and autologous bone graft fusion in the repair of thoracic spinal tuberculosis.
METHODA total of 30 cases of thoracic spinal tuberculosis were enrol ed. On the base of traditional thoracic spinal anterior surgical approach, the rib was reserved. Anterior distraction device was used to open the ribs for clearance and to move the focus of thoracic spinal tuberculosis. Autologous ilium was obtained and subjected to fusion and anterior plate fixation. Visual Analog Scale, Oswestry Disability Index, Frankel grade and Bridwel bone healing rating were used before and after treatment.
RESULTS AND CONCLUSION:A total of 30 patients were fol owed up for 3-60 months. The bone healing (class A) was seen, but no fistula formation was visible. Nerve compression symptoms were improved, without aggravating cases. Postoperatively, the average Cobb angle correction was 10.32°. After 6 months, imaging revealed bone fusion of affected vertebral body. After 18 months, the vertebral height was not lost obviously, no recurrence of vertebral tuberculosis. These results indicated that anterior intercostal space without cutting ribs exposed clearly, showing a large space, where can meet the requirement of first-stage debridement fixation and fusion in the repair of thoracic tuberculosis. The pathological changes were visibly clear;the focus was thoroughly removed, and the ribs were reserved. The outcomes are identical to rib resection. Simultaneously, autogenous iliac trilateral cortex has good supporting effects. Loose cancellous bone mesh has good osteogenesis and is helpful to bone healing.

Objective To investigate the methylation status of E-cadherin(E-cad)and its protein expression in human small bowel adenocarcinomas(SBAC),and the association of these findings with clinico-pathological characteristics.Methods E-cad gene hypermethylation and its protein expression in 36 patients with primary SBAC and the paired adjacent tissues were tested by methylation-specific PCR(MSP)assay and immunohistochemistry(IHC)respectively.Data associated with clinico-pathological characteristics was analyzed.Results The hypermethylation frequency of E-cad was 38.9% in cancerous tissues and 8.3% in adjacent tissues(P＜0.01).The positive rate of E-cad expression was 41.7% in cancerous tissues and 97.2% in adjacent tissues(P＜0.01).Twelve out of 21 cases without protein expression revealed methylated(P＜0.01).Methylation status was closely related to E-cad protein expression in SBAC.The hypermethylation of E-cad gene and the expression Of E-cad protein were significantly correlated with the depth of invasion,the differentiation and lymph node metastasis(P＜0.05),but were not correlated with other clinico-pathologic parameters such as age,sex,tumor size or location(P＞0.05).Conclusions The hypermethylation of E-cad gene can down regulate the protein expression,which closely related to the depth of invasion,the differentiation and lymph node metastasis.

To study the relationship between the different pulse conditions and photoplethymograms, the photoplethysmogram of 432 subjects, including normal pulse condition and 10 commonly - seen abnormal pulse, was examined at Cun - kou area with a BC - 4 quantitative photoplethysmograph. Meanwhile hemodynamic parameters were analysed. As compared with the normal pulse, photoplethysmograms of different pathological pulse conditions at Cun - kou area showed their specifical parameters and the changes of hemodynamic parameters reflected features of cardiovascular pathophysiology formed by different pulse conditions. It suggests that photoplethysmograms at the Cun -kou area can supply objective basis for clinical diagnosis of different pulse conditions.

Objective To compare the effect of hemodiafiltration(HDF) on the incidence rate of intradialytie hypotension. Methods We followed up eighteen patients with symptomatic hypotension history and divided them into group A and group B.Group A was treated with conventional hemodialysis(CHD) and HDF, Group B adopted HDF with low temperture hemodialysis. The number of hypotensive episodes, blood temperature during cardiopulmonary bypass, energy transfer rates were assessed. Results The incidence of symptomatic hypotension of patients was found lower in CHD (40%) than in HDF (6%),P<0.01. Energy transfer rates were founded higher in CHD than in HDF and low temperture hemodialysis, P<0.01. Conclusions HDF significantly reduced hemodialysis-related side effects and increased the tolerance ability of patients.

Expression and regulation of the P-glycoprotein (P-gp) is associated with the development of multidrug resistance in cancer.Cancer cells are exposed in endogenous damages from its own micro-environments and inflicted stimulated damages.These harmful micro-environments could trigger cellular stress response and regulated the expression of P-gp through various activated signal transduction pathways.Researches of the cellular endogenous micro-environments and exogenous stimulation damages on the expression and regulation of P-gp would have important significance for exploring the multidrug resistance of cancer cell.

This paper employed UPLC-Electrospray Ionization /Quadrupole-Time of Flight-Mass /Mass Spectrometry( UPLC-ESI/Q-TOF-MS/MS) to analyze the chemical constituents in the stems of Nelumbo nucifera. The stems of N. nucifera were extracted with 75% methanol, and we applied an Agilent Zorbax SB-Aq column (2.1 mm x 100 mm, 1.8 μm) to UPLC analysis with water methanol-water( containing 0.05% formic acid) in gradient as mobile phase. The eluates were then detected by ESI-Q-TOF-MS/MS. Results indicated that 22 benzylisoquinoline alkaloids were indendified. Among them, one alkaloid may be a new compound and a component was found in the Lotus for the first time. We fully identify the composition of the Lotus stems for the first time, Which could provides theoretical foundation for further study and utilization of the medicinal resources.
