1.2 had no significant difference between the unilateral MCA-M1 stenosis group and the control group.Conclusion Transcranial Doppler can help us to analyze collateral flow on the foundation of NVUE,and can also determine the qualitative and the semi-quantitative information of collateral flow.

Transient ischemic attack(TIA)is a common ischemic cerebrovascular disease,and the incidence of secondary ischemic stroke and cardiovascular events is very high.It needs to be assessed and managed urgently.The article presents the contents of emergency assessment of TIA,and emphasizes the importance of overall assessment.

The incidence of invasive fungal sinusitis is low, on the rising in recent years. But the misdiagnosis rate of the disease is high. In order to improve the level of early diagnosis and reduce the misdiagnosis, in this pa per, the invasive fungal sinusitis's clinical characteristics, diagnosis, treatment and prognosis are reviewed.

The incidence of oncocytic papilloma of nasal ethmoid sinus is very low. In order to improve the understanding of the disease for clinicians,we report one case of oncocytic papilloma in nasal ethmoid sinus. The case performs mainly congestion of the left nasal cavity, running pus nose and hyposmia. Nasal endoscopy found new creature in the meatus,and CT indicates soft tissue shadow in the left superior nasal passages,ethmoid sinus involved. Tumor is resected completely. There is no recurrence after five years follow-up.

Objective: By observing the differences in Western Ontario and McMaster Universities osteoarthritis index (WOMAC) and visual analog scale (VAS) scores in moxibustion treatment for moderate-to-severe primary knee osteoarthritis (KOA) with moxa of different storage years (3-year moxa and 1-year moxa from Qichun, Huanggang City, Hubei Province, China) through a randomized clinical trial, to objectively evaluate the differences in therapeutic efficacy of moxibustion with moxa of different storage years. Methods: A total of 63 patients with moderate-to-severe KOA who met the inclusion criteria were randomized into moxibustion group 1 and moxibustion group 2 by central randomization method, with 32 cases in moxibustion group 1 and 31 cases in moxibustion group 2. Moxibustion group 1 was treated with moxa stored for 3 years, and moxibustion group 2 was treated with moxa stored for 1 year. Dubi (ST 35), Neixiyan (EX-LE 4) and Heding (EX-LE 2) were selected in both groups, and the treatment lasted 20 min per time, 3 times a week. The immediate efficacy was compared after 6 times of treatment, and long-term efficacy was compared at follow-up 4 weeks after the end of treatment. Results: During the treatment, there were 2 dropouts in moxibustion group 1, and 1 dropout in moxibustion group 2. The total effective rate in the two groups was 83.3％ and 60.0％, respectively. Followed up at 4 weeks after the end of treatment, the total effective rate in the two groups was 80.0％ and 66.7％, respectively. There were no statistical differences between the two groups (both P>0.05). After treatment and 4 weeks after the end of treatment, the WOMAC and VAS scores in both groups decreased significantly compared with those before treatment (all P<0.01); the scores of stiffness item of WOMAC in moxibustion group 1 were lower than those in moxibustion group 2 (both P<0.05); there were no statistical differences in the scores of pain item and dysfunction item of WOMAC, and VAS scores between the two groups (all P>0.05). Conclusion: Moxibustion with moxa of different storage years (stored for 3 years and 1 year) both can improve the pain, stiffness and motor function in patients with moderate-to-severe KOA. While moxa stored for 3 years has a better therapeutic efficacy in improving stiffness of the knee joint than that stored for 1 year.

Objective To discuss the efficiency and safety of thalidomide combined with mFOLFOX in trea-ting advanced colon cancer.In addition,to observe the influence of mFOLFOX combined with thalidomide on serum vascular endothelial growth factor(VEGF)leveles.Methods One hundred patients with advanced colon cancer were divided randomly into two groups by digital table method.In the combined group,fifty patients were treated by mFOL-FOX combined with thalidomide.In the control group,fifty patients were treated by mFOLFOX alone.All the patients were tested serum VEGF before and after four cycle of chemotherapy.Results The response rate was 42% in the combined group vs.38% in the control group.Higher clinical benefit rate was found in the combined group (78% vs. 68%).The median time to progression(TTP)was 110 days vs.107 days.The differents between the two groups were not statistically significant(all P >0.05).After treatment of 4 cycles,the serum VEGF concentration of combined group and control group were respectively(317.40 ±55.54)ng/L and (330.84 ±64.48)ng/L,which were signifi-cantly decreased compared with pretreafment.The combination group decreased more obviously,the difference between the two groups were statistical significance(t =11.634,P =0.000).Conclusion Combined thalidomide with mFOL-FOX can′t improved clinical curative effect on the advanced colon cancer significantly.However,thalidomide can re-duce the levels of serum VEGF,and improve the quality of life.

ObjectiveTo evaluate the usefulness of an ultrasonography-based method to examine quadriceps femoris contracting. MethodsThe thickness of bilateral rectus femoris (RF) and vastus intermedius (VI) and the cross-sectional area (CSA) of RF was measured in 10 healthy subjects （n=20） in a relaxed position and 3 isometric contraction states using ultrasonography by two examiners. The date was compared with paired t test. Half of these subjects （n=10） were also measured with MRI at rest. The date was also compared with paired t test. ResultsThere was no significant difference between MRI and static compound ultrasonography, nor between two examiners. There was a significant difference (P<0.05) in thickness of RF and VI between relaxed and isometric contraction conditions. There was no significant difference among isometric contraction conditions. There was no significant difference among measurements of RF-CSA. Conclusionultrasonography shows good validity and reliability in measuring quadriceps shape.

Objective To observe the lumbosacral plexus nerves by diffusion tensor tractography (DTT) and quantitatively evaluate them by using diffusion tensor imaging (DTI) in healthy volunteers.Methods A total of 60 healthy volunteers (30 males and 30 females) underwent DTI scanning.Mean FA values of the lumbosacral plexus nerves (both sides of lumbar roots L3 to S1,proximal and distal to the lumbar foraminal zone) were quantified.Differences among various segments of lumbar nerve roots were compared with ANOVA test and SNK test.Differences between two sides of the lumbar nerve roots at the same lumbar segment were compared with paired-samples t test.Differences between the proximal and the distal nerve to the the lumbar foraminal zone at the same lumbar segment were compared with paired-samples t test.The lumbosacral plexus nerve was visualized with tractography.Results (1) The lumbosacral plexus nerve was clearly visualized with tractography.(2) Mean FA values of the lumbar nerve roots L3 to S1 were as followings:proximal to the left lumbar foraminal zone 0.202 ± 0.021,0.201 ± 0.026,0.201 ± 0.027,0.191 ±0.016,distal to the left lumbar foraminal zone 0.222 ± 0.034,0.250 ± 0.028,0.203 ± 0.026,0.183 ± 0.020,proximal to the right lumbar foraminal zone 0.200 ± 0.023,0.202 ± 0.023,0.205 ± 0.027,0.191 ±0.017,distal to the right lumbar foraminal zone 0.225 ±0.032,0.247 ±0.027,0.205 ± 0.033,0.183 ±0.021.Mean FA values were significantly different between the proximal nerve to the distal nerve in lumbar nerve roots L3,L4,S1 (t =-9.114-2.366,P ＜ 0.05),but not significantly different in L5 (P ＞ 0.05).Differences were not found between the right and left side nerves at the same lumbar segment (P ＞ 0.05).(3) The whole length of the lumbar roots nerve L3 to S1 can be visualized clearly by using DTT.Conclusions Diffusion tensor imaging and tractography can show and provide quantitative information of human lumbosacral plexus nerves.DTI is a potential tool for the diagnosis of lumbosacral plexus nerve disease.
