Repeated restraint stress (2 hours/day for 2 weeks) was given from 1 week after surgery. At the end of stress scheme, sucrose solution consumption test, open-field test and forced swimming test were performed. Results Spontaneous locomotor activity and coordination test were decreased to the lowest level on the 1st day after MCAO compared with the baseline values before surgery (P

The study of quality control of Chinese medicine has always been the hot and the difficulty spot of the development of traditional Chinese medicine (TCM), which is also one of the key problems restricting the modernization and internationalization of Chinese medicine. Multivariate statistical analysis is an analytical method which is suitable for the analysis of characteristics of TCM. It has been used widely in the study of quality control of TCM. Multivariate Statistical analysis was used for multivariate indicators and variables that appeared in the study of quality control and had certain correlation between each other, to find out the hidden law or the relationship between the data can be found,.which could apply to serve the decision-making and realize the effective quality evaluation of TCM. In this paper, the application of multivariate statistical analysis in the quality control of Chinese medicine was summarized, which could provided the basis for its further study.

Objective To explore the role of p170, MRP, bcl-2 in clinical drug- resistance and their correlation. Methods There are 44 acute leukemia(AL) patients, among them ANLL is 29, ALL is 15.The expression of p170, MRP, bcl-2 were detected. At last, the patients were divided into two groups: CR and NR according to efficacy after two periods standard chemotherapy. Results Overexpression of p170, MRP,bcl-2 were found in AL (P ＜0.05). The expression of p170 and MRP were lower in CR group than that in NR groups in AML and ALL; there were 22 of 24 patients expressed one or two proteins in NR groups and the expression of p170 in patients was concordant with that of MRP to certain extent (P ＜0.01). The overexpression of bcl-2 was related with the worse prognosis. The expression of bcl-2 was lower significantly in CR group than in CR and NR (P＜0.05). Conclusion p170, bcl-2, MRP are all associated with clinical MDR. High expression of these proteins is an unfavorable factor to prognosis. The expression of MRP and p170 showed coincidence, but showed no significance with expression of bcl-2 in untreated patients, it indicated that the drug-resistance mediated by p170 was different from bcl-2.

Objective To observe the effect of acupuncture and herbs on risk factors and prognosis of transient ischemic attack (TIA).Methods 120 patients received treatment from March to May 2011 in Gaomi People's Hospital and the Hospital of Gaomi were randomly divided into three groups,with 40 cases in each.Acupuncture and Chinese medicine group was treated with needling Neiguan and administered with modified Tianmagouteng decoction,3 times/d; Chinese medicine group was treated with modified Tianmagouteng diction exclusively,3 times/d; Western medicine group was treated with Aspirin,0.1 g,1 times/d.The three groups were treated for 30 d of two therapeutic courses.TCM syndrome score,blood pressure,blood lipids,blood rheology,blood sugar changes in the three groups of patients were observed before and after the treatment.And follow-up of elapse rate and the incidence of stroke in a year were observed.Results After treatment,① in the acupuncture and Chinese medicine group: the total cholesterol was (5.21 ± 0.97)mmol/L,whole blood viscosity was [(4.26±0.66) 200 mPa · s,(5.69±0.15) 30 mPa · s,(9.72±2.33) mPa · s],fibrinogen was (2.12± 0.46)g/L,systolic blood pressure was (124.13±9.96) mm Hg,diastolic blood pressure was (79.23±7.50) mm Hg,blood glucose was (5.59 ±0.78) mmol/L; in the Chinese medicine group,the total cholesterol was (5.43± 1.04) mmol/L,whole blood viscosity was [(4.25±0.25) 200 mPa · s,(5.46±0.55) 30 mPa · s,(9.81± 2.01) 5 mPa · s],fibrinogenwas (2.32±0.33) g/L,systolic blood pressure was (129.78±14.25) mm Hg,diastolic blood pressure was (79.54± 7.65) mm Hg,blood glucose was (5.60± 0.75) mmol/L; in the western medicine group,the total cholesterol was (5.52± 1.16) mmol/ L,full blood viscosity was [(4.12±0.54) 200 mPa · s,(5.45± 0.65) 30 mPa · s,(9.09 ± 1.11) mPa · s],fibrinogen was (2.41 ± 0.44) g/L,systolic blood pressure was (129.83 ± 14.91) mm Hg,diastolic blood pressure was (80.72±7.47) mm Hg,blood glucose was (5.75 ± 0.61) mmol/L.all these results were improved significantly than those before the treatment in the same group (P＜0.05),and the acupuncture and Chinese medicine group improved better than the other two groups (P＜0.05).② In 1-year follow-up,TIA recurrence rate of stroke in the acupuncture group were lower than the other two groups.Conclusion Acupuncture and Chinese medicine treatment were not only be able to improve the clinical symptoms of patients with TIA and blood pressure,blood lipids,blood theology,blood sugar and other risk factors for TIA patients significantly,but also can effectively reduced the relapse rate and the incidence of stroke.

Objective The aim of the study was to investigate the diabetic neuro-degeneration and its changes in neuroreaction to myocardial ischemia and reperfusion,by evaluation of the altera-tion of noxious thermal threshold and expression of substance P (SP),calcitonin gene related peptide (CGRP)in dorsal root ganglia in upper thoracic segments (T1-5 )in diabetic rats.Methods Thirty two male Sprague-Dawley rats,weighing 180-200g,were randomly divided into control group (group C)and diabetic group (group DM),1 6 rats in each group.rats in DM group were fed with high sug-ar-fat diet for 14 weeks and were given streptozotocin (STZ,35 mg/mg,i.p.)at the end of the 4 th week,to set up diabetes experimental model.The animals in control group were fed with standard la-boratory diet.Tail flick latency to thermal stimulation was measured weekly.At the end of 10 weeks after administration of STZ,diabetic rats (and rats in control group)were further divided into myo-cardial ischemia-reperfusion group (group IR)and sham operation group (group Sham).The left an-terior descending branch of coronary artery was occluded for 30 min followed by reperfusion for 120 min,establishing myocardial ischemia-reperfusion.The histological immunofluorescence assay and Enzyme-linked immunosorbent assay (ELISA)were carried out to evaluate the changes of the expres-sions of CGRP and SP in the dorsal root ganglia.Results The tail flick latency was significantly in-creased in group DM,compared to the group C (P < 0.01).The immunoreactive materials for CGRP and SP in the sensory neurons in dorsal root ganglia of upper thoracic segments (T1-5 )were markedly declined in group DM (P <0.01 or P < 0.05).Furthermore,levels of SP and CGRP were signifi-cantly lower in the DRG of the group IR after myocardial ischemia-reperfusion,compared to that in the group sham (P <0.01).Conclusion Diabetes causes sensory denervation and obvious reduction of expression of SP and CGRP in the sensory neuron innervating heart during myocardial ischemia-reper-fusion,indicating impairment of adaptive reactivity of neuro-endocrine function of cardiac sensory nerves.

Isocitrate dehydrogenase 1 (IDH1), a key rate-limiting enzyme in tricarboxylic acid cycle,is found within the cytoplasm and peroxisomes.In recent years, IDH1 mutation is discovered in most gliomaand its large scale metabolites, 2-hydroxyglutarate, may be involved in tumor as potential carcinogens, and isshown to be closely related to better patients' survival as well.IDH1 mutation is anticipated to be a novel genet-ic biomarker which will guide the treatments of clinical glioma.

Objective To compare the application of debridement combined with vacuum sealing drainage (VSD) versus debridement combined with conventional dressing change in patients with subscalp infection following surgical treatment of traumatic brain injury (TBI) and investigate the effect of VSD in treatment of wound infection associated with surgery for TBI.Methods A retrospective review was conducted on clinical data of 60 TBI patients with combined wound infection after decompressive craniotomy between August 2005 and January 2012.According to the treatment modalities after admission,the patients were divided into debridement combined with VSD group (Group A) and debridement combined with conventional dressing change group (Group B),with 30 patients per group.Then wound healing,infection relapse rate and length of hospital stay were compared between the two groups.Results All 60 patients were followed up for 12-36 months (mean 21.6 months).The wound infection did not recur after surgery in Group A and sutures were removed in time.Seven patients (23％) in Group B presented with recurrent wound infection after the removal of wound drainage tube,which was healed after an additional debridement and drainage as well as the delay of suture removal.Wound healing time (13 d vs 22 d),dressing change frequency (3 times vs 8 times),length of hospital stay (17 d vs 26 d),antibiotic use duration (7 d vs 14 d),and time to drop the body temperature to normal after operation (2 d vs 4 d) in Group A and B respectively showed significant difference (P ＜ 0.05).Conclusion In treatment of wound infection associated with decompressive craniotomy for TBI,VSD is beneficial for rapid healing of the infected wound and is worthy of wide clinical use.
