Plasma fibronectin(FN) level was measured by single radial immunod if fusion method in 58 patients with chronic Cor pulmonale during acute, remission and deterioration stages, 20 cases of chronic bronchitis, 10 cases of rheumatic heart disease, and 60 healthy people as controls.We analysed the relationship between the changes of plasma FN level and the degree of the respiratory failure, pulmonary infection and acid-base disturbance in experimental groups.The results showed that plasma FN levels of the controls, and the patients with chronic bronchitis and rheumatic heart disease were 322.4?60mg/L,263?40mg/L and 333.51 48mg/L, respectively.Plasma FN level was significantly decreased in patients with Cor pulmonale during acute stage(l46?67mg/L), gradually restored at remission stage (286?62mg/L) and markedly decreased in deterioration stage (101?39mg/L).It was ako markedly decreased in the patients with severe respiratory failure, pulmonary infection and acid-base disturbance.The authors suggest thai: placma FN may be used as a valuaole parameter to evaluate the clinical severity and prognosis of the patients with Cor pulmonale.The decrease of plasma FN level in patients with chronic Cor pulmonale may be due to its increased consumption and decreased synthesis in acute and deterioration stages.

OBJECTIVE:To observe clinical efficacy and safety of tegafur combined with three dimensional conformal radio-therapy for advanced esophageal carcinoma. METHODS:Totally 88 cases of advanced esophageal carcinoma admitted into Xuchang central hospital during Aug. 2013-Mar. 2016 were selected and divided into control group and observation group according to random number table,with 44 cases in each group. On the basis of anti-inflammatory,relieving asthma and other symptomatic treatment,two groups accepted three dimensional conformal radiotherapy. Control group was given fluorouracil 80 mg/m2,ivgtt,d1+nadeplatin 70 mg/m2,ivgtt,d1-d5. Observation group was given Tegafur capsules 60 mg,bid,continuous use 5 days,rest for 2 days. A treatment course lasted for 3 weeks,and they received 3 courses of treatment. Clinical efficacies of 2 groups were observed as well as serum inflammatory factors(TNF-α,IL-6,IL-8),lab indexes(VEGF,CA125,CA199,CEA),QLQ-C30 scores be-fore and after treatment. The occurrence of ADR was recorded in 2 groups. RESULTS:The total response rate of observation group was 88.64%,which was significantly higher than 68.18%,with statistical significance(P<0.05). Before treatment,there was no statistical significance in serum inflammatory factor levels,lab index levels and QLQ-C30 scores between 2 groups(P>0.05). Af-ter treatment,serum inflammatory factor levels and lab index levels of 2 groups were significantly decreased,while QLQ-C30 scores were decreased significantly;the observation group was significantly better than control group,with statistical significance (P<0.05). There was no statistical significance in the incidence of ADR between 2 groups (P>0.05). CONCLUSIONS:Tegafur combined with three dimensional conformal radiotherapy shows good therapeutic efficacy for advanced esophageal carcinoma,can significantly reduce serum inflammatory factor levels and lab index levels and improve life quality but do not increase the occur-rence of ADR.

Objective To investigate the curative effect of Aidi injection solution combined withcarboplatin on controlling malignant pleural effusion(MPE).Method A total of 86 cancer patients with appearedPME were selected as our subjected who hospitalized in the First People's Hospital of Shangqiu from Feb.2012to Mar.2013.They were randomly divided into the observation group(43 cases) and the control group(43cases).Patients in the oontrol group were treated with carboplatin at dose of 100 mg/per times which was putinto the thoracic cavity,and patients in the observation group was treated with Aidi injection solution at dose of100 mg/per times beside carbeplatin.The treatment period was 4 weeks.The effect information,quality of lifeand adverse reactions were recorded.Results The total effective rate and survival quality improvement rate inobservation group were 86.05％ (37/43) and 51.16％ (22/43),higher than those in control group (67.44％(19/43),30.23％ (13/43)),and the differences were significant(x2 =4.170,3.903 ; P ＜ 0.05).There wasno significant difference in terms of the related adverse reactions between two groups(P ＞0.05).ConclusionThe therapy of Aidi injection solution plus carboplatin on controlling MPE is proved to be effective and it canimprove patients' quality of life with better safety.Therefore it is worthy of recommendation.

As recent researches suggested,the continuous infusion and novel targeted medicines have been expected to improve the outcome of patients with aggressive B-cell non-Hodgkin's lymphoma.Nevertheless,it does not improve the curative effect by increasingly intensive dosage.Patients with aggressive T-cell non-Hodgkin's lymphoma have present better prognosis recently,which is attributed to better efficacy of the modified regimens in patients with NK/T cell lymphoma.Multiple genetic abnormalities are implicated in poorer prognosis in patients with aggressive T-cell non-Hodgkin's lymphoma.Non-myeloablative allogeneic stem cell transplantation and new targeted drugs have improved the curative effects.Radiotherapy with modern technology also is expected to become an important means to improve outcomes of aggressive non-Hodgkin's lymphoma.

Objective: To observe the histomorphology/pathology changes and the expression of hypoxia inducible factor-1 alpha (HIF-1?) and vascular endothelial growth factor (VEGF) in drowning rats brain, in an attempt to explore new pathways for treatment of water drowning. Methods: The animal model of freshwater drowning was established with rats. The rats were randomly divided into the following groups: control group, drowning-to-death group and 2 min-drowning group (including 5 subgroups survived for 3, 6, 12, 24. and 40 hours after being drowned in water for 2 min [n=10]). Brain indices of rats in each group were detected and the pathological changes of cerebral tissues were observed; the expression of HIF-lo and VEGF were detected immunohistochemically and the correlation between them was analyzed. The dynamic blood oxygen saturation was detected in rats survived for 40 h after 2 min-drowning at different points. Results: Brain index of the drowning group and groups surviving for 24, 40 hours after drowning were obviously higher than that of the control group (P

BACKGROUND:In recent years, neural stem cell transplantation has become a research hotspot in the treatment of brain injuries, such as cerebral ischemia, but the mechanism has not been fully elucidated.OBJECTIVE:To study the effect of neural stem cell transplantation on neuronal apoptosis and differentiation and neurobehaviors in cerebral ischemia rats.METHODS:Ninety Sprague-Dawley rats with cerebral ischemia were randomized into model group, phosphate buffer solution (PBS) group and neural stem cell group (n=30 per group). Another 30 rats were selected as sham operation group with vascular exposure but with no occlusion under anesthesia. Thirty normal 30 rats acted as controls with no treatment. Thereafter, neurological deficit scores, cerebral infarction volume, the number of apoptotic nerve cells,BrdU/NeuN and BrdU/GFAP expression were detected at 3, 7, 14 days after modeling.RESULTS AND CONCLUSION:On the 7th day and 14th day after modeling, the neurological deficit scores, cerebral infarct volume and the number of apoptotic nerve cells in the neural stem cell group were significantly lower than those in the model group and PBS group (P < 0.05), but there was no statistically significant difference between the model group and PBS group (P > 0.05). On the 3rd day, 7th day and 14th day after modeling, the neurological deficit scores and the number of apoptotic nerve cells in the control group and sham operation group were significantly lower than those in the model group, PBS group and neural stem cell group (P < 0.05). On the 3rd day after modeling, the BrdU/NeuN positive cell count in the model, PBS and neural stem cell groups showed no statistically significant differences (P > 0.05); on the 7th day and 14th day after modeling, the BrdU/NeuN positive cell count in the neural stem cell group was significantly higher than that in the model group and PBS group (P < 0.05), but the difference between the model group and PBS group was not statistically significant (P > 0.05). On the 3rd day, 7th day and 14th day after modeling, BrdU/GFAP positive cell count in the neural stem cell group was significantly lower than that in the model group and PBS group (P < 0.05),and the latter two groups had no statistically significant difference (P > 0.05). In summary, neural stem cell transplantation for cerebral ischemia contributes to the neuronal differentiation of endogenous neural stem cells in the subventricular zone of the lateral ventricles, reduce neuronal apoptosis, and ease ischemic damage to the rat neurological function.
