Objective: To investigate the expressions of signal transducer and activators of transcription 3 (STAT3) and suppressor of cytokine signaling 3 (SOCS3) protein in the breast carcinoma tissue and their relationship with tumor differentiation, invasion, and metastasis. Methods: The expression of STAT3, phospho-STAT3 and SOCS3 protein were determined by tissue microarray and immunohistochemistry with EnVision system in 71 cases of archival breast carcinoma tissues and 41 cases of noncancerous tissues. The relationship between their expression and the clinical pathological parameters were analyzed. Results: (1) The positive rates of STAT3, phospho-STAT3, and SOCS3 was 78.9%, 69.0%, and 29.6%, respectively. The difference was significantly different compared with control (P<0.01, P<0.01, and P<0.05). (2) The expressions of STAT3 and phospho-STAT3 were positively related with the histological grade, the axillary lymph node metastasis, and the clinical stage (P<0.01), but not related with the age, the tumor size, and the histological grade of breast carcinoma tissues (P>0.05). The expression of SOCS3 was negatively related with the histopathologic grade and the axillary lymph node metastasis (P<0.05), but was not related with the age, histological type, the tumor size, and the clinical stage (P>0.05). (3) The expression of STAT3 and phospho-STAT3 had negative correlation with the expression of SOCS3 in breast carcinoma tissues (P<0.01). Conclusion: The overexpressions of STAT3 and phospho-STAT3 and the down-regulated expression of SOCS3 closely correlated with the tumor carcinogenesis, progression, invasion, and metastasis of breast carcinoma. Detection of their expression is helpful in accessing the malignant degree and the biological behaviors of breast carcinoma.

Objective To study the effects and current mechanism of low concentration of lidocaine on evoked-bursting (EB) firing of dorsal root ganglion (DRG) neurons in rat model of chronic compression (CCD) of DRG . Methods Twenty-four SD rats were divided into normal control group (n=12) and CCD model group (n=12). CCD group was treated with chronic oppression on L4 and L5 DRG with L shape bar. Normal control group received no treatment. In vivo intracellu?lar recording was used to record the incidence of EB and the effect of lidocaine on subthreshold membrane potential oscilla?tion (SMPO). Patch clamp recording was used to record the effect of lidocaine on persistent sodium current (INaP). Results The incidence of EB increased in CCD group( 45.97%, 57/124), which was significantly different when compared with nor?mal group (χ2=26.810, P<0.01). The magnitude of SMPO, INaP and EB were inhibited in a reversible way by lidocaine (50μmol/L). Conclusion The low concentration of lidocaine might play an analgesic effect in peripheral nervous system by se?lectively inhibiting INap, which participates in SMPO formation.

Objective To study the effect ofQianzheng powder through point directional transdermal drug delivery technique for the patients with urge incontinence(UI) after stroke.Methods Seventy patients with UI after stroke were randomly divided into treatment group and control group(each group 35 patients). Qianzheng powder through point directional transdermal drug delivery was given to the treatment group, but the tolterodine through mouth was given to the control group. The urinary diary and bladder function at baseline and after 2 weeks' treatment were observed.Results After treatment, the total effect rate(88.2%vs. 63.6%,χ2=5.575) in the treatment group were better than that in the control group (P<0.01).The duration of voided (17.05 ± 6.21 times/48 hvs. 28.63 ± 9.62 times/48 h,t=5.872), the times of urinary incontinence (2.08 ± 1.24 times/48 hvs. 7.19 ± 2.46 times/48 h,t=10.784), the average voided volume (282.38 ± 14.32 mlvs. 185.82 ± 15.43 ml,t=26.561), the times of nocturia (1.38 ± 0.34 times per nightvs. 2.45 ± 1.56 times per night,t=3.906), the initial Sensory capacity of bladder (246.76 ± 21.95 mlvs. 176.43 ± 20.64 ml,t=13.502), the maximum capacity of bladder (495.80 ± 26.72 mlvs. 295.81 ± 28.46 ml,t=29.663), the residual urine volume (12.25 ± 6.83 ml vs. 33.63 ± 7.25 ml,t=12.428) in the treatment group showed significantly more improvement than those in the  control group (P<0.01).Conclusions TheQianzheng powder by point directional transdermal drug delivery could reduce the symptoms of urinary incontinence, and improve the life quality of patients with UI after stroke.

OBJECTIVE:To analyze the rationality of the preventive use of antibiotics in Chinese ophthalmologic patients with type Ⅰ incision.METHODS:By means of retrospective study,a total of 1 273 ophthalmologic cases from 113 hospitals of 2006～2007 from National Monitoring Network of Ministry of Health for Clinical Application of Antibiotic with type Ⅰ incision involving preventive administration of antibiotics via different routes were analyzed.RESULTS:The local administration (eye drops and local injection) was rational on the whole,but the systemic administration (intravenous or oral administration) was irrational to some degree in which the drug grade was on the high side,the antibacterial spectrum was inappropriate,and the medication time was delayed.CONCLUSION:Preoperative local administration and rational use of dosage forms should be emphasized in the preventive use of antibiotics for patients undergoing ophthalmologic surgery.

Objective:Based on Co-occurrence Matrix and Run-length Matrix,we studied cerebral infarction patients' MR image texture characters.The aim is to investigate the differences of lesion textures characters between patients' groups and normal control groups,so that we can use this tiny change to realize early diagnosis of cerebral infarction.Methods:Texture features were extracted from MR images of patients and normal control groups respectively.Fisher test was applied to choose valid textures characters and made features classifier.Results:Linear discriminant analysis can achieve 88.31% classification accuracy.This demonstrated that cerebral infarction patients and normal control groups have the differences of textures Characters in MR image.Conclusion:We can discover cerebral infarction patients' MR image texture characters change by texture analysis,so that early diagnosis of cerebral infarction would be realized.
