ABSTRACT
Objective To investigate the value of serum high sensitive C reactive protein(hs-CRP) in the risk stratification and prognosis evaluation in the patients with coronary heart disease and PCI operation.Methods One hundred and sixty-three cases of coronary heart disease and undergoing PCI in this hospital from March 2013 to September 2015 were selected and performed the coronary angiography examination before operation.Then the patients were divided into 3 groups according to the hs-CRP level.The Gensini score was used to judge the blood vessel stenosis degree.The patients were followed up within six months after surgery.The major cardiovascular events were recorded and the relationship between the hs-CRP level with the number of diseased vessels,Gensini score,MACE and other coronary heart disease risk factors was analyzed.Results Hypertension and hs-CRP level had statistically significant difference among 3 groups(P＜0.05);preoperative hs-CRP level showed positive correlation with hs-cTnT level (r =0.44,P＜ 0.001),while the hs-CRP was negatively correlated with the HDL-C level (r =-0.18,P =0.003);with the Gemini score elevation,the hs-CRP level was similarly elevated,the hs-CRP levels in the patients with severe,moderate and mild vascular stenosis evaluated by Gensini's score were(17.11±9.58),(10.02±3.59),(4.11±1.62)mg/L respectively,the difference among them had statistical significance(F=37.21,P＜0.05).Within postoperative six months,the MACE occurrence rates in 3 groups were 32.1％,52.9 ％ and 59.2 ％ respectively,the differences among the three groups were statistically significant(x2 =13.523,P =0.001),and the target lesion blood supply reconstruction rate had statistically significant difference(x2 =7.522,P =0.022).The hsCRP level was an independent risk factor of MACE occurrence(OR =2.06,95 ％ CI:1.31-3.42,P=0.005).Conclusion Serum hs-CRP is an independent risk factor for cardiovascular events occurrence after PCI surgery in the patients with coronary heart disease.
ABSTRACT
Objective To analyze the curative effect of oxaliplatin combined with S-1 in the treatment of advanced colorectal cancer.Methods Totally 90 cases of patients with advanced colorectal cancer in Shangluo No.2 Provincial People's Hospital from January 2013 to August 2015 were divided into observation group and control group,45 cases in each group.Patients in control group were treated with oxaliplatin combined with fluorouracil,4 weeks for one cycle of treatment,and patients in observation group were treated with oxaliplatin combined with S-l,21 d for one cycle.The curative effects,adverse reactions,life quality,and one year survival rate were compared between two groups.Results After treatment,the total remission rate of observation group was higher than that of control group,and the disease control rate was lower than that of the control group,but there was no significant difference between the two groups.During the treatment,there were no significant differences in Ⅰ degree and Ⅱ degree adverse reactions between two groups;But the adverse reactions of level Ⅲ and level Ⅳ of gastrointestinal reaction,liver function damage,reduce the incidence of white blood cells in observation group were significantly lower than that of control group (P ＜ 0.05).There was no significant difference between the two groups in the SF-36 scale scores.The one year survival rate of observation group was (21/45),and the survival rate of the control group after treatment was 42.22％ (19/45) in the control group,and there was no significant difference between the two groups in the one year survival rate.Conclusion Compared with oxaliplatin combined with fluorouracil,oxaliplatin combined with S-1 has equivalent efficacy and life quality,but the adverse reactions in gastrointestinal tract,liver,and marrow were better.
ABSTRACT
A large ischemic stroke caused by malignant middle cerebral artery infarction can lead to severe cerebral edema, even cerebral hernia. This condition deteriorates and progresses rapidly, usually leading to death. Due to limitations of conservative treatments, decompressive hemicraniectomy becomes a favored option in clinic. Recent years, a series of ex?perimental studies and clinical trials achieved reliable evidence that decompressive hemicraniectomy is an effective treat?ment for patients who suffer from malignant middle cerebral artery infarction. With the successful surgical procedure, most patients benefit from a reduced mortality and improved functional outcome without severe disability. Nevertheless, plenty of issues about decompressive hemicraniectomy still need to be solved. Here, we reviewed researches of early diagnosis of ma?lignant middle cerebral infarction and the application of decompressive hemicraniectomy as its treatment.
ABSTRACT
We synthesized the superparamagnetic paclitaxel nanoparticles from modified chitosan tangling around Fe3O4 ferrofluid and taxol, and observed the nanoparticles with transmission electronic microscopy (TEM). Then we evaluated the paramagnetism of the particles by vibration specimen magnetometer (VSM) and tested their cytotoxicity with flow cytometry (FCM). The prepared nanoparticle solution was black without any floccule or sediment and appeared transparent after diluted. The nanoparticles were spherical and dispersed in water with mean diameter of 15 nm under TEM and showed superparamagnetic character. FCM test showed the nanoparticles had significant toxic effects against malignant astrocytoma U251 cell lines, equal to taxol alone. These results showed that the superparamagnetic nanoparticle not only enhanced the solubility of paclitaxel in water, but also was superparamagnetic and cytotoxic, which make suitable tools for magnetic targeting chemotherapy of brain gliomas.

Objectives To evaluate the effectiveness of transcarotid artery chemotherapy for gliomas after surgery, and selection of drug, avenue of administration, and optional time for the therapy. Methods Beginning from 4 to 30 days after operation, Nimustine (ACNU, Japan) 2.5mg/kg was injected per carotid artery, once every week for three times as one course. A second course of treatment was given after an interval of 4 to 6 weeks. Results With the above regime, the effect was marked in 39 cases (18.8%), fairly effective in 44 cases (20.8%), only slightly effective in 59 cases (27.8%), no effect in 61 cases (28.8%), and failure in 5 cases (2.4%), the mean survival time was nearly 100 weeks. Conclusion Transcarotid artery chemotherapy for gliomas is helpful in prolonging survival period, with little side effects, easy to carry out, less expensive, and better accepted by the patients.
ABSTRACT
Purpose: To retrospectively analyse the characteristics of diagnosis and operative treatment of 66 cases of scwannoma in the spinal canal. Methods: Sixty-six cases, 27 of the cervical region, 13 the thoracic and 26 of the lumbar and sacral regions were treated from 1983 to 1996. Clinical manifestation and types, and results of spinal radiography, myelography, CT scannig, MR imaging, operative treatment were separately described. Results: All of the 66 cases obtained timely and accurate diagnosis and treatment. The tumors in 60 patients were completely resected; and in remaining 6 patients subtotal excision was performed. The duration of follow-up averaged two years and eleven months and excellent and good results were achieved in 90.9% of the patients. Conclusions: 1) Schwannoma in the spinal canal is not uncommon; four in this series are malignant or with malignant tendency. 2) The forms of the tumor are with lots of variations. 3)An approximate position of the lesion can be determined by clinical neurological examination. Accurate diagnosis can be made by a procedure combining clinical and imaging examinations, operative exploration and pathological examination. 4) Total resection of the tumor may result in good restoration although it is sometimes difficult and risky.
ABSTRACT
Objective To investigate the effective mechanism, time and rational dose of radiotherapy of epileptic rat. Methods To make rat model of epilepsy, and give 0, 24,12 or 6Gy X ray irradiation, and then detect the amino-acid contents in frontal lobe of those rats in 1 hour, 24 hours or 1 week after radiotherapy. Results Glu and GABA are the key amino-acids in radio effection. After 12Gy or 24Gy irradiation there were low Glu, high GABA and low Glu/GABA in frontal lobe of rat. After 1h, 24h and 1 week irradiation, the contents of GABA raised up while the ratio of Glu/GABA declined with a remarkable decline at 24h. Conclusions Radiotherapy to epileptic rat may set off a rapid and enduring change of GABA and Glu transmitters, and 12Gy may be the rational radio dose for epileptic rat.
