Objective To evaluate the medial longitudinal arch of the foot with and without hallux valgus in order to establish the relationship between hallux valgus and the arch. Methods 34 feet of 24 cases with hallux valgus and 34 normal feet of 18 cases were investigated by roentgenography. On the dorsal plantar view while weight-bearing standing, the hallux valgus angle (HVA), the first intermetatarsal angle, and the position of the tibial sesamoid relative to the first metatarsus were measured respectively. On the lateral view while weight-bearing standing, the top angle of the medial longitudinal arch, the anterior angle of the medial longitudinal arch (also named as the first metatarsal inclination angle) and the relative height of the talus, which are similar to measurement of the height of the medial longitudinal arch, were measured respectively. The characteristics of the medial longitudinal arch of the feet with and without hallux valgus were compared, and the correlation between the height of the medial longitudinal arch and the severity of the hallux valgus, which were manifested by the hallux valgus angle, first intermatatarsal angle, the relative position of the tibial sesamoid, was analyzed. Results The top angle of medial longitudinal arch was 136.9??7.6? in hallux valgus feet and 126.7??2.1? in normal feet; the anterior angle of medial longitudinal arch was 10.8??2.6? in hullux valgus feet and 16.6??1.6? in normal feet; the relative ratio of height of talus was 0.159?0.03 in hallux valgus feet and 0.199?0.01 in normal feet , there was significant difference between two groups. While with the increase of the lateral displacement of tibial sesamoid, the angle of hullxus valgus and the first intermetatarsal angle, the top angle of medial longitudinal arch became larger, the anterior angle of arch became smaller, and the relative height of talus became lower. The medial longitudinal arch of the foot with hallux valgus was collapsed, and there was moderate to high relationship between the height of the medial longitudinal arch and the severity of the hallux valgus. Conclusion Hallux valgus is a three dimensional deformity, which will disturb the normal biomechanics of the foot.

[Objective]To evaluate the clinical result of Weil osteotomy for refer metatarsalgia in hallux valgus. [Method]Between 2004 and 2005, 25 feet of 17 patients with hallux valgus were treated by osteotomy at the base of the first metatarsal and Weil osteotomy of the lesser metatarsal with metatarsalgia. Weight-bearing anterior-posterior and lateral X ray were taken before the surgery and 6 weeks after surgery on follow up. The hallux valgus angle , the intermetatarsal angle between 1st and 2nd metatarsal, and length of the second metatarsal were measured on the X-ray film. AOFAS system was used to judge the clinical result of the surgery. [Result]The hallux valgus before surgery angle was 32??5.7?,after surgery it was 12.8??3.5?; the intermetatarsal angle between lst and 2nd metatarsal before surgery was 24.2??3.7?,after surgery it was 10.5??0.7?; AOFAS score was 45.6?6.9 before surgery , and 86.9?4.6 after surgery ; significant difference was found between the result. The metatarsal after Weil osteotomy was shorten by 3~8 mm, mean 4.5 mm. After surgery 18 feet had pain free, and 7 feet had a signigicant pain relief . All the patient could return to normal life without other treatment. [Conclusion ] The biomechanical changes in the foot with hallux valgus should be analyzed before surgery . Combined use of base osteotomy at the first metatarsal and Weil osteotomy at lesser metatarsal can get satisfactory clinical result in patients with sever hallux valgus and transferred refer metatarsalgia.

Objective:To study the protective effect of electro-acupuncture on glutamate(GLU),glycine(GLY),aspartate(ASP)and NF-?B expression in rat with cerebral ischemia reperfusion.Methods:The middle artery occlusion(MCAO)model was established and high pressure liquid chromatography(HPLC)fluorescence assay was used to detect contents of glutamate(GLU),glycine(GLY)and aspartate(ASP)in rat brain.The effect of electro-acupuncture on the nervous dysfunction score,the water content of cerebral constitution and the expression of NF-?B were observed.The group with non-acupoint group was as control.Results:The nervous dysfunction score,the water content of cerebral constitution,NF-?B,GLUand ASP in model group were higher than those of the sham-operated group.GLY levels had no obvious changes,there was no significant diference between the model group and the non-acupoint group.The nervous dysfunction score,the water content of cerebral constitution,the expression of NF-?B,GLU and ASP in electro-acupuncture group were lighter than that of the model group,GLY levels had no obvious changes.Conclusion:Electro-acupuncture could protect brain cell from damage after focal cerebral ischemia reperfusion injury by inhibiting the cerebral expression of NF-?B and excitatory amino acid.

Objective To investigate the diagnostic value of anti-cyclic citrullinated peptides ( CCP ) antibodies combined rheumatoid factors (RF) on elderly patients with rheumatoid arthritis.Methods From January 2012 to December 2014, 29 cases of elder patients in our hospital with rheumatoid arthritis (elder RA group, age >60 year), 47 cases of elderly health control group (elder RA group, age≥60), and 48 cases of elder patients without rheumatoid arthritis (non-elder RA group, age<60 year) were selected.The anti-CCP antibodies and rheumatoid factor (RF) levels of three groups were detected, and the significance of anti-CCP antibody combined RF on the diagnosis of elderly rheumatoid arthritis was analyzed.Results Diagnostic positive rate of anti-CCP antibodies +RF was significantly higher than that of anti-CCP antibodies, and the difference was significant (χ2 =7.632, P =0.006).Diagnostic positive rate of anti-CCP antibodies +RF was higher than that of RF, but the difference was not statistically significant (χ2 =3.107, P=0.078).The diagnostic positive rate of anti-CCP antibodies, RF, and anti-CCP antibodies +RF for diagnosis of elderly rheumatoid arthritis had no statistically difference with that of non-elderly RA group.The sensitivity and negative predictive value of anti-CCP antibodies +RF was higher than that of only anti-CCP antibodies and RF.The area under the ROC curve of detecting anti-CCP +RF was 0.786, which was higher than that of anti-CCP antibodies (0.699) and RF (0.663), indicated that the reliability of anti-CCP antibodies +RF was higher than that of anti-CCP antibodies and RF.Conclusion The anti-CCP antibodies and RF can diagnose elderly rheumatoid arthritis, and anti-CCP antibodies combined RF has more clinical significance.

Objective: To investigate the relationship between blood pressure variability and ambulatory arterial stiffness index (AASI) in both normal subjects and hypertensive patients.
Methods: A total of 280 consecutive subjects without antihypertensive medication were studied. All subjects received ambulatory blood pressure monitoring (ABPM) and AASI was calculated as 1 minus the regression slope of diastolic blood pressure value vs systolic blood pressure value according to ABPM recording.
Results: ① There were 161 subjects with male gender, 138 patients with hypertension, and the average age was (50.4 ± 13.3) years.②Pearson analysis indicated that AASI was related to age (r=0.272, P<0.001), 24-hour mean pulse pressure (r=0.504, P<0.001) , nocturnal diastolic blood pressure dipping (r=-0.334, P<0.001) and standard deviation of 24-hour diastolic blood pressure (r=-0.520, P<0.001).③AASI in anti-dipper hypertensive patients was higher than that in dipper patients, P<0.05;while AASI between dipper and non-dipper patients, dipper and extreme-dipper patients were similar, P>0.05 respectively.④Multiple linear regression analysis demonstrated that with adjusted age, gender, BMI and blood pressure, AASI was independently related to 24-hour mean pulse pressure (β=0.003, P<0.001), nocturnal diastolic blood pressure dipping (β=-0.001, P<0.05), standard deviations of 24-hour systolic blood pressure (β=0.032, P<0.001) and 24-hour diastolic blood pressure (β=-0.064, P<0.001), standard deviation of 24-hour heart rate (β=0.006, P<0.001).
Conclusion:AASI is closely related to blood pressure variability, it’s a comprehensive index for arterial stiffness and blood pressure variability.

Objective To evaluate the expression of human kallikrein10 (KLK10) in different endometrioid tissues and analyse the relationship of KLK10 with ER and PR in endometrioid adenoearcinoma.Methods The expression of KLK10 protein in 12 normal endometria,19 endometrial hyperplasia and 34 endometrial carcinoma were detected by immunohistochemistry.The correlations of the expression of KLK10 protein,ER and PR were analyzed.Results The expression of KLK10 in stage Ⅰ,Ⅱ and Ⅲ were 64.3 ％(9/14),30.0 ％ (3/10),10.0 ％ (1/10),and the difference was statistically significant (P ＜ 0.05).The expression of KLK10 in endometrial carcinoma,normal endometria,endometrial hyperplasia were 66.7 ％ (8/12),33.3 ％(4/12),10.0 ％ (1/10),and the difference was statistically significant (P ＜ 0.05).The expression of KLK10 in G1,G2,G3 were 66.7 ％,33.3 ％,10.0 ％,and the difference was statistically significant (P ＜ 0.05).The positive rate of KLK10 expression was 38.2 ％ and the positive rates of ER and PR expression were 67.6 ％and 55.9 ％,respectively,in 34 endometrial carcinoma.The expression of KLK10 was positively correlated with ER and PR expression (x2 =0.448,P ＜ 0.01).Conclusion Absence or down-regulated expression of KLK10 may play an important role in the formation and development of endometrioid adenocarcinoma.The low expression of KLK10 is correlated with low expression of ER and PR in endometrioid adenocarcinoma.The positive expression of KLK00,ER and PR predicts a better prognosis.

ObjectiveTo test the expression of epidermal growth factor-like domain 7 (EGFL7),microvessel density (MVD) and foeal adhesion kinase pY397 (FAKpY397) in human glioma tissues,and to evaluate their relationship.MethodsThe expression of EGFL7 and FAKpY397 in 56 cases of human glioma and 8 cases of normal brain tissues were detected by immunohistochemistry test,and MVD was detected by CD34 staining.ResultsThere was a significant difference of the positive rates of EGFL7 between normal brain tissue (0) and gliomas (75％),χ2 =17.45,P ＜0.01.With the increased pathological grade,the expression level of EGFL7 increased (χ2 =26.24,P ＜ 0.01 ).There was a significant difference of the positive rates of FAKpY397 between normal brain tissue ( 12.5％ ) and gliomas (73.2％),χ2 =6.23,P ＜ 0.05.With the increased pathological grade,the expression level of FAKpY397 increased (χ2 =6.71,P ＜ 0.01 ). MVD on normal brain was( 15 ± 4 )/HP,on Ⅰ - Ⅱ grade and Ⅲ -Ⅳ grade gliomas was ( 27 ± 3 )/HPand ( 60 ± 4 )/HP respectively,there was a significant difference on MVD between normal brain tissue and gliomas (P ＜ 0.01 ).Higher level of MVD was found in gliomas with higher grade ( P ＜ 0.01 ).There was a positive correlation between EGFL7 and FAKpY397 expressions in gliomas (r =0.314,P ＜0.01 ).There was a significant difference on MVD between positive and negative expression of EGFL7 ( t =26.55,P ＜ 0.01 ). MVD was (56 ± 4 )/HP and (25 ± 3 )/HP respectively.ConclusionThe expression of EGFL7 of human gliomas has a favorable positive correlation with the degree of malignancy,MVD and FAKpY397.It is indicated that EGFL7not only palys an important regulative role in glioma neovascularization,but also it may participate directly in glioma occurrence and invasion.

Objective To evaluate the efficacy of minimally invasive percutaneous intervertebral disc approach for treatment of sympathetic cervical spondylosis. Methods Fifty?six patients diagnosed as having sympathetic cervical spondylosis from January 2009 to August 2014, aged 22-64 yr, with the dis?ease course ranged from 6 months to 15 yr and a follow?up period of 6 months, were enrolled in the study. The related minimally invasive approach was selected according to the height of the diseased intervertebral space. When the ratio of the height of diseased intervertebral space∕normal intervertebral space≤1∕3, per?cutaneous radiofrequency ablation was used ( groupⅠ, n=19); when the ratio within the range of 1∕3-2∕3, percutaneous laser disk decompression was used ( groupⅡ, n=12); when the ratio≥2∕3, low?tem?perature plasma radiofrequency ablation was used ( group Ⅲ, n=25) . Before operation, at 2 weeks after operation, and at 1, 3 and 6 months after operation, the sympathetic symptoms were evaluated using the 20?point score. At 2 weeks and 6 months after operation, the patients′ subjective satisfaction was assessed and graded ( excellent, good, medium and poor ) . Results All the patients were followed up for 6 months. The sympathetic symptom scores were significantly lower at each time point after operation in Ⅰand Ⅲ groups and at 2 weeks and 3 and 6 months after operation in group Ⅱ than those before operation
( P<0.05) . The excellent and good rate of patients′subjective satisfaction was 67.9% at 2 weeks after op?eration, and 76.8% in the last follow?up period at 6 months after operation. Conclusion The minimally invasive percutaneous intervertebral disc approach has a marked short?term effect on sympathetic cervical spondylosis.

AIM: To study the expression of thrombospondin-1 (TSP-1) and receptor-CD36, and investigate the relationship between tumor invasive capability and microvessel density and thrombospondin-1. METHODS: 43 hepatocellular carcinoma (HCC) cases were under investigation. Tissues from tumor, corresponding adjacent non-HCC tissue were stained with CD34 to show the MVD. TSP-1 and CD36 were examined by immunohistochemistry (SP) and RT-PCR. Relationship between clinical pathological features and above parameters was analyed. RESULTS: The staining of TSP-1 in HCC tissue is significantly lower than that in corresponding adjacent non-HCC tissue. Expression of TSP-1 was correlated to tumor thrombi, capsule, tumor invasive capability and CD36. CD36 was also correlated to tumor thrombi and tumor invasive capability. MVD was significantly higher in TSP-1, CD36 positive group than that in negative group. CONCLUSION: TSP-1 inhibits the growth, invasion and angiogenesis in HCC. TSP-1 may take effect through CD36.

Objective To study the clinical efficacy of computer-assisted stereotactic brain transplantation of human retinal pigment epithelium (hRPE) cells into the patients with Parkinson disease (PD). Methods Under the guidance of computed X-ray tomography and magnetic resonance imaging image mergence, 4 × 106 hRPE cells were transplanted into the putamen and ventriculus laterlis of 17 cases of PD by stereotactic surgery. The transplantation sites were contralateral to the side of main symptoms and signs. The curative efficacy were observed at the 7th day, 1st month, and 3rd month after the transplantation. Results The contralateral symptoms were ameliorated continuously after the transplantation. Three months after the surgery, the total effective rate of cell transplantation was 88. 2 %, and 82. 4 % of the cases got significant improvement. The cases that got ipsilateral improvement soon after the surgery gave a total effective rate as high as 88. 2 % at the 3rd month during follow-up period, and 64. 7% among these cases improved significantly. Only a minority of cases had transient dizziness and hemiparesis, but the duration was short. Conclusion The therapy, computer-assisted stereotactic transplantation of hRPE ceils in the treatment of PD, is safe and efficient.
