OBJECTIVETo assess the efficacy of Yishen Jiejing Decoction (YJD) in treating poststroke shoulder-hand syndrome (SHS) patients of yin deficiency yang hyperactivity with blood stasis stagnation collaterals syndrome.

METHODSTotally 60 SHS patients of yin deficiency yang hyperactivity with blood stasis stagnation collaterals syndrome were randomly assigned to two groups, the treatment group and the control group, 30 cases in each group. Conventional rehabilitation training and therapeutics were applied in all patients. Besides, patients in the treatment group took 50 mL YJD, twice a day. One month without interruption consisted of one course of treatment. The curative effects of each group were evaluated respectively before treatment and at one month after treatment. The neurologic impairment, TCM syndrome, and the improvement of upper limbs movement were assessed by the neurologic impairment integral, scoring for TCM syndrome diagnostics, Fugl-Meyer Assessment (U-FMA). Adverse reactions were observed at the same time.

RESULTSThe effective rate of stroke was 86.67% and the effective rate of SHS was 90.00% in the treatment group, higher than those of the control group (P < 0.05). Both groups got improvement in neurologic impairment, stroke induced blood stasis syndrome, yin deficiency yang hyperactivity syndrome, and the improvement of upper limbs movement after treatment (all P < 0.05). Besides, all the improvement was obviously superior in the treatment group (P < 0. 05). No adverse reaction occurred during the course of treatment.

CONCLUSIONThe curative effect of YJD combined with conventional rehabilitation training was confirmative and superior to the control group.

Objective To asses stereoacuity and the factors that influence stereopsis in children after unilateral cataract extraction.Methods Sixty-two children who were diagnosed as unilateral cataract and underwent cataract extraction with intraocular lens implantation were included in this study.Data are recorded on age at presentation and the surgery,the presence of strabismus,the refractive error,and the best corrected distant visual acuity (BCDVA) of both eyes and stereoacuity.Sixty-two patients were followed up for 14 ～ 60 months.Results Sixty-two patients were divided into two groups according to stereoacuity.Thirty-one patients in group A achieved stereopsis better than 400 s of arc.Group B had 31 patients whose stereoacuity was poorer than 400 s of arc.The mean age at presentation and surgery were 4.6 ± 3.4 and 6.3 ±4.5 years in group A and 2.1 ±2.1 and 2.4 ±2.2 years in group B.51.6％ of patients in group A achieved a BCDVA of 20/40 or better,but in group B,only 6.5％ of patients achieved a BCDVA of 20/40.Those who had strabismus after cataract surgery were 6.5％ in group A and 35.5％ in group B.There was statistically significant difference in age at presentation and the surgery (t =4.03,4.53,P ＜0.01),good BCDVA(x2 =15.34,P ＜ 0.01) and absence of strabismus (x2 =7.88,P ＜ 0.01) between two groups.Conclusions Stereopsis can develop in children after pediatric unilateral cataract extraction and intraocular lens implantation.Good stereoacuity is correlated with later manifesting cataracts,absence of strabismus and good BCDVA.

Objective To evaluate which parameters of transvaginal color Doppler ultrasonography(TVCDU) can effectively reflect blood flow in ovarian tumors. Methods TVCDU was preoperatively used to determine all the parameters of blood flow in 60 women with epithelial ovarian cancer(EOC) and 36 with benign ovarian cystadenomas (control group). Microvessel density(MVD) was tested in the tissue samples by immunohistochemical method(SP method). The parameters of TVCDU in EOC were compared with those in control group.The correlation between MVD and the parameters in EOC group and control group was analyzed. Results ①Statistical differences of arteria showing rate, arteria number, vasculature type, diastolic notch, PI, RI, S/D, TAMXV were seen between EOC group and control group(P

[Objective]To demonstrate mechanism of ESW in curing osteogetic disorders,we studied expression of some osteogenetic factors in human mesenchymal stem cells(hMSCs)when exposed to ESW.[Method]After success in marrow aspiration,isolation and obtainment optimal experimental energy,a dose of 5kV and 100 times of ESW was applied to hMSCs of passage 1.The expression of IGF-Ⅰ and TGF-?1 were examined by immunocytochemical staining.[Result]The cytochemical staining results showed that expression of IGF-Ⅰ and TGF-?1 appeared at different passage of hMSCs after ESW intervention.Appearance of IGF-Ⅰ was earlier than TGF-?1 which didnt express until passage 7.At the same interval,the expression of IGF-Ⅰ and TGF-?1 in control group difference is lower than ESW group,respectively(P

AIM To investigate the possible role of the mitochondrial transmembrane potential (??m) and caspase 3 in arsenic trioxide(As 2O 3)-induced apoptosis of cancer cells. METHOD Namalwa, SGC7901 and Bcap37 cell lines were used as in vitro models. Apoptosis was confirmed by sub-G 1 cells content as well as phosphatidylserine(PS) externalization. The ??m was detected on flow cytometry through double staining of Rhodamine 123(Rh123) and popidium iodide(PI). In addition, the effect of DEVD-CHO, a selective inhibitor of Caspase 3, on As 2O 3-induced apoptosis was studied. RESULT The As 2O 3-induced apoptosis closely associated with the externalization of the ??m and the activation of Caspase 3. As 2O 3 induced cells necrosis when Caspase 3 was inhibited. CONCLUSION As 2O 3 may selectively activates Caspase 3 after it induces externalization of ??m, which causes cancer cells apoptosis.

RNAi is a process of effective gene silencing. Human papillomaviruses 16 (HPV16), as the most prevalent genotype of cervical cancer, encodes the E6 and E7 oncogenes, which is pivotal for maintenance of malignant phenotypes. Recently, some significant advances have been obtained in RNA interfering effect on HPV16 E6/E7. In vitro, it has been developed more effective vector systems and screened for more specific targeted sequences. In vivo, the corresponding animal models have been established, which lay a good foundation for the clinical research.
