Chinese Medical Equipment Journal 2003;0(10):-
Objective To evaluate retrospectively ECG -gating for the coronary angiography with MSCT. Methods 15 patients were studied with a multislice spiral CT on retrospective ECG -gating,0.5s rotation, and cardial segment reconstruction algorithm. Nine phases were chosen to reconstruct images of coronary arteries. Results In the 230 coronary artery segments,213 (91%)were best visualized at 70%. And 15 (6.4%), 9 (3.8%), and 3 (1.3%) were optimal at 80%, 40% , and 5% of the cycle respectively. Conclusion The coronary arteries usually are best visualized at 70% image reconstruction window of the cardial cycle.
2.Effects of Sec-O-Glucosylhamaudol on expressions of nitric oxide and interleukin-6 in Lipopolysaccharide stimulated murine macrophage
Chinese Journal of Immunology 2015;(11):1486-1489
Objective:To investigate the effect of Sec-O-Glucosylhamaudol on inflammatory mediator and cytokine( NO and IL-6)production in Lipopolysaccharide(LPS) stimulated murine macrophage(RAW264.7).Methods: Macrophages were induced with LPS,and incubated with different concentrations of Sec-O-Glucosylhamaudol(20,40,80 μg/ml),the quantity of NO production was measured by Griess reagent;the IL-6 production were measured by enzyme linked immunosorbent assay(ELISA),the expression of nitric oxide synthase( iNOS) in cells were detected by Western blot;the expression of iNOS and IL-6 mRNA were analyzed by real-time PCR.Results:Each concentrations of Sec-O-Glucosylhamaudol(20,40,80 μg/ml) inhibited the production of NO and IL-6 in LPS-stimulated RAW264.7 cells(P<0.01).This compound also reduced the mRNA expression of iNOS and IL-6.Conclusion:Sec-O-Glu-cosylhamaudol exhibited anti-inflammatory activity by inhibited the NO and IL-6 production in LPS stimulated RAW264.7 cells.

Chinese Journal of Primary Medicine and Pharmacy 2014;(24):3690-3692
Objective To observe the effect of octreotide combined with percutaneous catheter drainage on pancreatic pseudocyst ( PPC ) .Methods 89 patients choosen with PPC were randomly divided into the octreotide combined with percutaneous catheter drainage group(observation group,n=43) and octreotide group (control group, n=46).The control group were subcutaneous injected octreotide 0.1mg q 8 h.The observation group were subcutane-ous injected octreotide 0.1mg q 8 h with ultrasound or CT-guided percutaneous drainage for 4 weeks to place more drainage tubes when there were multiple cysts,drainage not free when washing drainage tube and drainage tube posi-tion adjustment.After 4 weeks rechecked the pancreas CT and curative effect was analyzed.Results The observation group cure rate and total effective rate were 65%,100%,the average hospitalization time was (16.8 ±12.1) d.The control group were 39%,85%,(26.8 ±19.4) d,the differences between the two groups were statistically significant(χ2 =6.01,χ2 =7.10,t=2.89,P<0.05,P<0.01).Conclusion Octreotide combined percutaneous catheter drainage on PPC has good curative effect,small trauma,high success rate,less complications,shorter hospitalization time.It is the preferred method for the treatment of PPC.

Objective:To observe the clinical efficacy of chemotherapy for esophageal cancer in the elderly. Methods: A total of 74 patients diagnosed with esophageal cancer in our hospital were randomly divided into the observation group and the control group. The control group was treated with radiotherapy alone, while the observation group was treated with concurrent chemoradiotherapy. The efficacy, adverse reactions and 1 and 2-year survival were observed. Results:The recently response rate was 86.5% in the observation group, while the control group was 62.2% (x2=5.37, P<0.05). The disease control rate was 100.0% in the observation group, while it was 3.8% in the control group. The differences were significant (x2=4.53,P<0.05). The adverse reactions in the two groups were not significantly different. With 34 patients in the observation group followed up, the 1-year survival rate was 73.5%, 2-year survival rate was 55.9%, while it was 40.0% and 25.9% in 35 patients that followed up in the control group. The differences were statistically significant (x2=6.58,x2=5.32;P<0.05).Conclusion: Concurrent chemotherapy for esophageal cancer in the elderly has a significant effect. Compared with radiotherapy alone, it can significantly increase the 1, 2-year survival rate, and does not significantly increase the adverse reactions.

Chinese Journal of Biochemical Pharmaceutics 2017;37(5):77-79
Objective To investigate the clinical effect of sodium hyaluronate combined with glucocorticoid on the treatment of periarthritis of shoulder.Methods106 patients in department of orthopedics, the second hospital of Ningbo with periarthritis of shoulder were randomly divided into 2 groups (n=53).The control group were treated with anti-inflammatory and analgesic treatment, at this basis, the study group were treated with sodium hyaluronate combined with Glucocorticoid.5 weeks for a course of treatment.Levels of serum inflammation, laboratory-related indicators were compared.ResultsCompared with before treatment, shoulder joint activity in the two groups increased, VAS score decreased, the scores of strength of shoulder joint, range of motion and daily activities increased, levels of serum IL-6, IL-10, TNF-α decreased(P<0.05).Compared with the control group, scores of activity in the study group were higher, VAS scores were lower, scores of strength of shoulder joint, range of motion and daily activities were higher, levels of serum IL-6, IL-10, TNF-α were lower(P<0.05).The effective rate in the control group(73.59%) was lower than the study group(90.57%), but there was no statistical difference.ConclusionThe effect is accurate which sodium hyaluronate combined with glucocorticoid was used in the treatment of periarthritis of shoulder, and it can reduce the inflammation index and improve the joint activity.

Protein tyrosine kinase genes are the largest family of oncogenes. This is not surprising since protein tyrosine kinases are important components of signal transduction pathways that control cell shapes, proliferation, differentiation, and migration. This review will address the recent progress in understanding the function of Eph receptor and ephrin ligands in normal development and how disregulation of these functions could promote tumorigenesis.

[Objective]To evaluate the radiographic and clinical results of locking compression plate and interlocking intramedullary nail in the treatment of distal tibial shaft fracture(4 to 11cm proximal to tibiotalar joint).[Method]A total of 65 cases of distal tibia shaft fractures were retrospectively reviewed from 2003 to 2007.Thirty-seven cases were treated with locking compression plate as group A,and 28 cases were treated with interlocking intramedullary nail as group B.According to AO classification system,32 cases were type A,12 were type B,21 were type C.[Result]All cases were followed up for 12-24 months(mean,16.5 months).Five cases were found delayed or nonunion,with 1 case in group A and 4 cases in group B.One case in group A and 2 cases in group B were found developed deep infection.Two cases in group A and 8 cases in group B received second operation.The good-to-excellent rates of ankle joint function were 91.9% in group A and 71.4% in group B.The good-to-excellent rates of knee joint function were 97.3% in group A and 78.6% in group B.[Conclusion]Distal tibial shaft fracture could be treated successfully with either percutaneous plates or intramedullary nails.Percutaneous locking plate is better than intramedullary nail in aspect of prevention of delayed union,malunion and second operation.

Objective To investigate the changes of serum pituitary hormones and thyroid hormones in patients with severe brain injuries during hypothermia therapy. Methods Ninety-eight patients with severe brain injuries were randomly divided into mild hypothermia group (50 cases) and control group (routine therapy group,48 cases). The levels of serum PRL,TSH,FT 3 and FT 4 of patients in the both groups were detected by two-side sandwich immunological autochemoluminescence detection system before and after treatment. The therapeutic effects were observed and compared. Results After treatment,the levels of serum PRL,TSH and FT 4 of patients in hypothermia group were (0.25? 0.02) nmol/L ,(0.7?0.2) mU/L and (15.0?5.3) pmol/L,respectively,which were significantly lower than that in control group,ie,(0.46?0.04) nmol/L,(1.1?0.3) mU/L and (21.2? 6.4) pmol/L ,respectively. The good recovery rate (62%) in hypothermia group was higher than that of control group (35%) but the death rate (22%) in hypothermia group was lower than that of control group (42%). Conclusions Mild hypothermia can inhibit the rise of serum pituitary hormones and thyroid hormones after severe brain injury and improve the therapeutic effects.
