Objective To observe the effect of electric-impulse stimulation to Jiaji points (EX-B2) on spinal cord injury (SCI). Methods Totally 126 eligible SCI patients were randomized into a treatment group and a control group, 63 cases in each group. The control group was intervened by conventional rehabilitation training plus acupuncture, while based on which the treatment group additionally received electric-impulse stimulation to Jiaji points (EX-B2). The spasticity, function, and activities of daily living (ADL) were evaluated 90 d later. Results The spasticity score was significantly changed after intervention in the treatment group(P＜0.01). Tendon reflex and spasticity score were significantly changed in the control group (P＜0.01). After intervention, there was a significant difference between the two groups in comparing spasticity score (P＜0.01). The changes of motor function and sensory function scores in the treatment group were significantly different from that in the control group (P＜0.01, P＜0.05). The Barthel Index (BI) scores were significantly changed in both groups after intervention (P＜0.05). There was a significant difference in comparing the BI score between the two groups after intervention (P＜0.05). Conclusion Electric-impulse stimulation to Jiaji (EX-B2) plus conventional rehabilitation training can significantly improve spasticity, and the motor and sensory functions, and promote the recovery of activities of daily living.

Objective To analyse the expressions and clinical significances of CXCR4,CXCL12 and PTEN in breast cancer.Methods The expressions of CXCR4,CXCL12 and PTEN in 60 cases of breast cancer were detected by immunohistochemistry technique SABC method.The correlations of levels of CXCR4,CXCL12 and PTEN expression and the age of patient,tumor diameter,histological grade,TNM stage,lymph node metastasis,ER status,Her-2 status,and vessel invasion were analysed.Twenty cases of breast fibroadenoma tissues and 20 cases of normal breast tissues were analysed as controls.Results The expressions of CXCR4 (x2 =48.754,P =0.000),CXCL12 (x2 =47.611,P =0.000) and PTEN (x2 =19.994,P =0.000) in breast cancer,normal breast tissues and breast fobroadenoma showed significant differences.The positive expressions of CXCR and CXCL12 were significantly correlated with histological grade (x2 =11.080,P =0.004;x2 =6.978,P =0.031),TNM stage (x2 =9.819,P =0.007;X2 =10.163,P =0.006),lymph node metastasis (x2 =6.213,P =0.013;x2 =8.031,P =0.005),ER (x2 =12.774,P =0.000;x2 =7.330,P=0.007),vessel invasion (x2 =5.860,P=0.013; x2 =5.185,P=0.020) and Her-2 (x2 =5.487,P =0.019;x2 =4.689,P =0.030).The expression of PTEN in breast cancer was significantly correlated with TNM stage (x2=7.366,P =0.025),lymph node metastasis (x2 =5.511,P =0.019) and ER state (x2 =4.077,P =0.043).There was a positive correlation between the expression of CXCR4 and the expression of CXCL12 in breast cancer (r =0.336,P =0.004).There was a negative correlation between the expression of CXCR4 and the expression of PTEN in breast cancer (r =-0.362,P =0.004).There was a negative correlation between the expression of CXCL12 and the expression of PTEN in breast cancer (r =-0.360,P =0.004).Conclusion The high expression of the chemokine CXCL12 and its receptor CXCR4 and the low expression of PTEN are closely related to the carcinogenesis and metastasis of breast cancer,which may play an important role in the development of breast cancer.

Objective The aim of the study is to investigate whether the progressive incremental exercise can induce the change in bone maximum force.Methods One hundred and seventy healthy SD rats,aged 3 months,were used as samples after adaptive exercise for one week,and then they were divided to a basic control group(C_0),8 control groups and 8 exercise groups according to the training duration(2W,4W,6W,8W,9W,11W,13W and 15W).Based on Bedford and our pre-study.the longest training duration of the rats was 15 weeks.The maximum force(F) of femoral bone and the 2nd lumbar vertebrae(L_2)were tested by three-point bending test and compressive test separately.Results It was shown that there was no pronounced difference in F of femoral bone between con trol groups and exercise groups.But significant differences in F of L_2 were found between the control groups and exercise groups(P<0.001).Conclusions Changes in different degree were found in the F of femoral bone and L_2 during the process of growth.The differential effects of incremental exercise on F were caused by the difference in training intensities and in the bone types.

Fifty cases of mild - moderate cerebrovascular dementia selected by referring to the diagnositic criterion DSM- I -R for cerebrovascular dementia (VaD) established by America Society of Psychoneurology issued by WHO were randomly divided into Shen Tong Capsule treatment group (30 cases) and hydergine treatment group (20 cases). Modified Mental State Examination (MMSE) and Blessed Behavior Scale (BBS) were used to calculate changes of marks before and after treatment for assessment of therapeutic effects. Results show that Shen Tong Capsule has therapeutic effect on key symptoms and clinical behaviour of mild - moderate disturbance of intelligence, with the total effective rate of 86. 67%. Differences of accumulated marks in both MMSE and BBS before and after treatment in the treatment group are superior to those of the control group respectively.

Objective To investigate the relationship between serum insulin-like growth factor 1 (IGF1) and metabolic syndrome ( MS) . Methods Four hundred and sixty-five subjects were enrolled and divided into two groups: MS group( n = 255) and non-MS group as control(n = 210). Fasting levels of blood glucose (FBG), insulin (Ins) , C peptide (Cp) , cholesterol (Cho) , triglyceride (TG), lower-density lipoprotein cholesterin ( LDL-C) , higher-density lipoprotein cholesterin ( HDL -C), lipoprotein a (Lpa), serum IGF1, postprandial 2 hours blood glucose (PBG), and BMI were measured in these persons. Results The levels of IGF1, Cp, FBG, PBG, CT, TG, LDL-C, BMI were higher, and HDL-C was lower in MS group than those in non-MS group (all P

Objective To investigate the changes of serum insulin-like growth factor-2 (IGF-2) and insulin-link growth factor binding protein-3(IGFBP-3) in the patients with ovarian cancer before and after operation,and evaluate their clinical significance.MethodsThe contents of serum IGF-2 and IGFBP-3 in 82 patients with ovarian cancer were detected by ELISA before and after operation and compared with that in health controls.ResultsThe contents of IGF-2 in the patients before operation were significantly higher than that in control group[(101.5±22.2)ng/ml,(49.3±15.6)ng/ml vs (69.6±17.7)ng/ml,(23.9±11.3)ng/ml,t＝3.74,2.85,P＜0.05].The contents of IGFBP-3[(39.8±11.1)ng/ml]in the patients before operation were significantly lower than that in control group[(55.8±19.2)ng/ml](t′＝4.49,P＜0.05).There was significant correlation between the contents with lymph node metastasis and clinical stage[(107.5±24.0)ng/ml,(41.7±16.9)ng/ml vs (91.6±17.7)ng/ml,(56.9±19.1)ng/ml;(103.4±27.2)ng/ml,(50.2±16.6)ng/ml vs (86.6±12.3)ng/ml,(41.1±17.1)ng/ml,t＝2.83,2.37,2.48,3.32,P＜0.05).The contents of IGF-2 was significantly decreased,and IGFBP-3 was significantly increased in patients after radical operation [(86.6±12.3)ng/ml,(41.1±17.1)ng/ml vs (103.2±26.0)ng/ml,(45.3±14.9)ng/ml,t′＝3.46,t＝2.67,P＜0.05].But there was no significant difference on the level of IGF-2 and IGFBP-3 before and after palliative resection(P＞0.05).ConclusionsThe contents of serum IGF-2 and IGFBP-3 are closely related to tumor invasion,metastasis and clinical stage.Dynamic determination of the contents of serum IGF-2 and IGFBP-3 may be an important index for evaluation of invasion,metastasis,efficacy and prognosis for the patients with ovarian cancer.

Objective: To confirm the pathogenesis and diagnosis of pediatric Fisher's syndr ome.Methods: Clinical manifestations and Cerebrospinal fluid (CSF) were compared and studied in 22 patients diagnosed as Fisher's syndrome.Results:Twenty- two cases of Fisher's syndrome both had the characteristics of ophthalmoplegia and cerebella ataxia,and had different degrees of incomplete fl accid paralysis in the ar ms and legs. In about half of 22 cases, the CSF showed divergence phenomenon of the protein and cell. Conclusion: Fisher's syndrome is a specific or variant type of AIP involving the cranial nerves, in which the cerebellar ataxia is taken as a main symptom and sign .

OBJECTIVE: To explore the effect and mechanism of kidney-warming and astringent therapy in treating nephrotic syndrome patients with deficiency of spleen and kidney yang and overflow of water, and to observe the change of plasma endothelin and interleukin-2 receptor after treatment. METHODS: Forty-four patients were randomly divided into conventional steroid treated group (control group, 20 cases) and conventional steroid plus kidney-warming and astringent therapy treated group (treatment group, 24 cases). The levels of plasma endothelin (ET) and soluble interleukin-2 receptor (sIL-2) were observed. RESULTS: Before treatment, plasma ET and sIL-2 in the patients were significantly higher than those in healthy people (P<0.01). After treatment, the ET and sIL-2 levels were obviously improved in both treated groups (P<0.05) and the improvement in the treatment group was more obvious. The difference between the two treated groups after treatment was significant (P<0.05). CONCLUSION: Conventional treatment plus kidney-warming and astringent therapy can effectively improve the levels of plasma ET and sIL-2 in treating nephrotic syndrome patients with deficiency of spleen and kidney yang and overflow of water, and hence alleviate the damage of renal tissue.
