Objective To investigate the efficacy and safety of compound kushen injection (CKI)in the treatment for patients with advanced liver cancers.Methods Relevantly randomized controlled trials from China National Knowledge Infrastructure (CNKI),Chinese Science and Technology Journal Database (VIP),Wanfang Data,and Pubmed were searched until November,2014.Randomized controlled trials (RCTs) of supportive care compared with combined therapy of CKI in the treatment for patients with advanced liver cancers were included.The methodological quality of RCTs was assessed independently with bias risk according to the Cochrane collaboration.All data were analyzed with the Review Manager 5.3.Results Eight RCTs involving 472 patients were included.The meta-analysis results suggested that the shortterm efficacy of the treatment group be higher (P =0.008) and that the pain relief be a significant benefit in the treatment group (P ＜0.01).Adverse reactions were not observed.Conclusions CKI is an effective and safe adjuvant drug for advanced liver cancers.

Background Studies showed that microRNA (miR)-375 suppresses the growth,apoptosis,migration and adhesion of tumor cells,and it plays a regulation to the changes of vascular endothelial growth factor (VEGF) in tumor tissue to arrest neovascularization.However,whether miR-375 intervenes the formation of new blood vessel in eyes is unelucidated.Objective This study was to explore the effects of miR-375 on human retinal capillary endothelial cells (HRCECs) function induced by hypoxia.Methods HRCECs were cultured using IMDM and divided into normal control group,CoCl2 model group,CoCl2 +miR-375 mimic group,CoCl2 +miR-375 mimic control group,CoCl2+miR-375 inhibitor group and CoCl2 +miR-375 inhibitor control group,and hypoxia cell models were created by adding 200 μmol/L CoCl2.MiR-375 and frizzled 4 (FZD4) small interfering RNA (siRNA) were transfected into the cells by 50 nmol/L miRNA lipidosome for 48 hours.The proliferation of the cells was detected by MTT assay;migrated number of the cells was examined by Transwell chamber assay;ELISA was employed to detect the concentrations of VEGF and VE-cadherin in the medium;the expression of β-catenin,cyclinD1,matrix metalloproteinase-2 (MMP2) and VEGF proteins were analyzed by Western blot;tube length of vessel formation was evaluated by Matrigel assay.Cultured cells were divided into normal control group,CoCl2 model group,CoCl2 +mock group and CoCl2 + FZD4 siRNA group,the relative expression of FZD4,a miR-375 targeted gene,was detected by luciferase reporter.Results The relative expression of miR-375 mRNA was significantly increased in the CoCl2 +miR-375 mimic group compared with the CoCl2 + miR-375 mimic control group and reduced in the CoCo2 + miR-375 inhibitor group compared with the CoCo2 + miR-375 inhibitor control group (t =-19.237,8.764,both at P＜0.01),with a higher transfected efficacy for miR-375.The cell proliferative fold,migrated cell number,VEGF and VE-Cadherin contents in the medium and the tube length were significantly different among the CoCl2 model group,CoCl2 +miR-375 mimic group,CoCl2 +miR-375 mimic control group,CoCl2 +miR-375 inhibitor group and CoCl2 +miR-375 inhibitor control group (F =24.324,26.776,14.113,19.225,15.040,all at P＜0.001),and those in the CoCl2 +miR-375 mimic group were evidently reduced in the CoCl2 +miR-375 mimic group compared with the CoCl2 +miR-375 mimic control group,while those in the CoCl2 +miR-375 inhibitor group were considerably elevated in comparison with the CoCl2 +miR-375 inhibitor control group (all at P＜0.01).The expressions of β3-catenin,cyclinD1,MMP2 and VEGF protein were significantly different among the normal control group,CoCl2 model group,CoCl2 +miR-375 mimic group,CoCl2+miR-375 mimic control group,CoCl2 +miR-375 inhibitor group and CoCl2 +miR-375 inhibitor control group (F=11.753,13.283,16.770,10.334,all at P＜0.001).In addition,the cell proliferative fold,migrated cell number and the tube length were significantly increased in the CoCl2 model group and CoCl2+mock group,and those in the CoCl2+FZD4 siRNA group were decreased in comparison with the CoCl2 +mock group (all at P＜0.05).Conclusions MiR-375 inhibits the growth,migration and tube formation ability of HRCECs in hypoxic status probably by regulating the activation of Wnt pathway via directly targeting FZD4.

Objective To investigate the value of image analysis technology of polari-light dermoscopy (PD) in diagnosing head and face tumors. Methods We randomly collected the head and face tumors from the patients in this hospital, and then diagnosed them with naked eyes and PD, respectively. After making sure the diagnosis by histopathology, we analyzed the results retrospectively. Results We summarized the diagnostic signs of 211 head and face tumors on dermoscopy, which shown a great specificity. Its diagnosis rate reached to 92.89 %, obviously higher than that (69.67 %)with naked eyes. Due to clinical misdiagnosis and erroneous treatment, the recurrence rate of skin lesions was 19.91 %. The top 3 of head and face tumors, in turn, was seborrheic keratosis, melanocytic tumor and basal cell carcinoma. Conclusions PD is a non-invasive image analysis technology, which is especially applicable to the early diagnosis of head and face tumors. It can make sense in decreasing blind biopsy, directing surgical excision areas effectively, and selecting reasonable remedy. It also has great significance in the recovery and beauty of skin lesions.

Objective To investigate the early diagnosis of vitiligo and its differential diagnosis from other depigmentated diseases using polarized light dermoscopy(PD)imaging analysis.Methods Patients with localized depigmented macules were enrolled into this study.PD was used to observe the micromorphology,feature and color of skin lesions.Histopathology was performed to confirm the diagnosis of all cases except for those of pityriasis versicolor which were confirmed by clinical and laboratory examination.Results Of the 176 patients.97 were diagnosed as vitiligo.Residual perifollicular pigmentation Was observed in 91.94%(57/62)of patients with progressing vitiligo and 62.86%(22/35)of those with stable vitiligo,with significant difference between the two groups of patients(P<0.05).However.residual perifollicular pigmentation was absent in the 79 non-vitiligo depigrnented cases.The presence of telangiectasia,early reservoirs of pigmentation and perilesional hyperpigmentation were related to the stage of vitiligo and treatment history of patients.Conclusions PD,which efficiently eliminates the interference of reflected light on skin lesions of vililigo,is an imaging technique that allows for the visualization of minor structures and features of the skin lesions that are indiscernible to naked eyes.In a nutshell,the application of PD has offered references to the early diagnosis of vitiligo and its differential diagnosis from other depigmentation diseases.

BACKGROUND: The risks in pregnancy to the developing fetus result in cerebral palsy after delivery. Therefore, the study on etiology of cerebral palsy should transfer to biological field of embryonic development and stress on multi-factor analysis on relevant environment of pregnant mother,hereditary factors and relevant diseases.OBJECTIVE: To analyze the main risks of incidence of infantile cerebral palsy.DESIGN: Pair design at ratio of 1:2 and Logistic regression analysis of multi-factors were applied.SETTING: Prevention Medical Research Room of Jiamusi University and Department of Epidemiology, College of Public Health, Harbin Medical University.PARTICIPANTS: Totally 103 cases of infantile cerebral palsy were collected from Jiamusi Treatment and Education Center of Cerebral palsy,Shanyang Pediatrics Hospital and Qingdao Pediatrics Hospital from December 2002 to September 2003, of which, 68 cases were male and 35 cases were female. The guardians were in the know and agreed with the investigation. The pair principle at ratio of 1:2 was adopted, based on which, 206 cases of sick children with non-cerebral palsy and disorders in neurological system and healthy children treated at same period in the hospitals were collected as the control. The match conditions in the control were same sex, same nationality and difference in age ± 3 months.sy and healthy children was self-designed. The investigated items included mainly: Factors before delivery (hereditary factors): family history of similar disease; mother's factor: general situations, such as occupation, educational background and age of delivery; behavioral factors of birth: including times of pregnancy, times of delivery and abnormal delivery; healthcare and nutrient in pregnancy: such as examination before delivery and intakes of various foods; sickness or abnormal manifestations in pregnancy: including pathogen infection, pregnant syndromes and vaginal bleeding; medication in pregnancy, fetal placents factors: such as neck winding, mass weight of birth, twin pregnancy, factors during delivery (complications in delivery,methods of delivery) and neonatal factors (various kinds of disorders in neonates). Questionnaire of investigation was performed by looking-up medanalysis was done on single factor and multi-factors. The factors that presented statistical significance in single-factor analysis, significant difference (P ＜ 0.05) and P value near to 0.05 were adopted to establish the model of multiple Logistic regression of main risks of cerebral palsy and conditional Logistic regression analysis was carried on.MAIN OUTCOME MEASURES: Analysis on the effects of factors before delivery, during delivery and in neonatal phase on incidence of cerebral palsy.RESULTS: Totally 103 cases of cerebral palsy and 206 cases of healthy factors: Occupation of mother was associated with cerebral palsy. Worker and age ≥34 years were the risks of cerebral palsy (OR=13.333, 2.864,eating fish and sea products in pregnancy, pre-delivery body temperature,mass weight of birth ＞ 4 000 g and pregnant weeks of 37 to 42 were the protective factors of cerebral palsy (OR=0.028-0.576, P ＜ 0.05-0.01); abnormal delivery history and vaginal bleeding in pregnancy were the risks of ery: Apgar score and caesarian section were the protective factors of cerebral palsy (OR=0.458, 0.343, P ＜ 0.01); forceps delivery and delivery with oxytocin were the risks ofcerebral palsy (OR=16.338, 2.116, P ＜ 0.01,of newborn and neonatal intracranial hemorrhage were the risks of cerebral sion analysis: Forceps delivery was the highest risk (OR =70.668) and the sequence risk degree from high to low was asphyxia of newborn, elder age of pregnant mother, vaginal bleeding in pregnancy and abnormal mass weight of birth (OR=19.083-4.138, P ＜ 0.05-0.01). Eating fish and sea products in pregnancy and caesarian section were the protective factors (OR=0.324; 0.262, P ＜ 0.01, 0.05).CONCLUSION: Risks of cerebral palsy are mainly focused on pregnant period and perinatal period. It is suggested to prevent and eliminate actively various risks of cerebral palsy before, during and after delivery (such as forceps delivery, asphyxia of newborn, elder age of pregnant mother,vaginal bleeding in pregnancy and abnormal mass weight of birth) so as to reduce the incidence rate of cerebral palsy.

Objective:To evaluate the clinical effects of oncoplastic breast-conserving surgery on patients with early breast can-cer near the mammary areola. Methods:A total of 60 patients with early breast cancer underwent breast-conserving surgery in the Sec-ond Department of Breast Surgery, Tangshan People's Hospital from February 2011 to November 2013. These patients were random-ized into two groups, namely, the experimental Group A (n=30) and the control Group B (n=30). Oncoplastic breast-conserving surgery was performed on the patients in Group A, whereas Group B underwent standard breast-conserving surgery. The specimen weight of the locally excised breast, the nearest distance of the tumor to the surgical margins, and the postoperative cosmetic result of the affected breast were compared between the two groups. Results: The specimen weights of the locally excised breast were 71.03 ± 12.92 and 41.53±7.13 g, and the nearest distances of the tumor to the surgical margins were 13.30±2.97 and 10.63±1.65 mm in Groups A and B, respectively, with significant differences between the two groups (P<0.05). The postoperative satisfaction rates of the affected breast were 93.33%and 83.33%in Groups A and B, respectively, without any significant differences between the two groups (P>0.05). Con-clusion:A larger amount of excised breast tissue and a wider scope of surgical margins were observed in Group A patients. However, the postoperative cosmetic result of the affected breast was almost similar for both groups. Therefore, oncoplastic breast-conserving sur-gery is a feasible and effective approach for early breast cancer patients.

AIM: To investigate the effect of Dendranthema morifolium (Ramat) Tzvel (DM) on isolated rat heart and ventricular myocytes during ischemia/anoxia and reperfusion/reoxygenation.METHODS: The Langendorff perfused rat hearts were used to measure intraventricular pressure and coronary flow. The cell contraction and intracellular calcium transient in enzymatically isolated ventricular myocytes were determined. RESULTS: (1) DM (0.5 g/L) significantly attenuated the inhibitory effects induced by ischemia/reperfusion on left ventricular developed pressure (LVDP), ?dp/dt max, coronary flow and LVDP?HR, meanwhile increased the content of SOD and decreased the content of MDA in the myocardium; (2) DM (0.5 g/L) attenuated the inhibitory effects of anoxia and reoxygenation on [Ca 2+]i transient and cell contraction in isolated ventricular myocytes. CONCLUSION: DM attenuated the effects on contractility and intracellular calcium induced by ischemia/anoxia and reperfusion/reoxygenation in the isolated rat heart and the ventricular myocytes. The mechanism might be related to increase in SOD activity and maintaining [Ca 2+]i homeostasis.

Objective To explore the effect and potential mechanism of suppressors of cytokine signaling 3 (SOCS3) knockout on cell viability and apoptosis of retinal ganglion cells (RGCs) after optic nerve injury.Methods The optic nerve transection was used to construct optic nerve injury model of rats,and RGCs were isolated after optic nerve injury.The experimental animals were divided into optic nerve transection injury (ONT) group and sham-operation (Sham) group.The expression of SOCS3 in RGCs was detected by Western blot and RT-PCR in each group.Subsequently,SOCS3 siRNA was transfected into RGCs of Sham group and ONT group,and the experimental were further subdivided into blank control group,negative control group and SOCS3 silence groups.Cell viability was measured by CCK8 and MTr methods.Apoptosis was detected by Hoechst 33342 staining and flow cytometry.Furthermore,the mTOR siRNA and SOCS3 siRNA were co-transfected into RGCs,and cell viability and apoptosis were detected.Results The expression of SOCS3 was dramatically increased at 3 days after injury in the ONT group when compared with Sham group (P =0.049),and it showed an increased tendency gradually along with the extension of injury time.Compared with the blank control in the ONT group,SOCS3 silence markedly promoted cell viability [(49.47 ± 7.35) ％ vs.(73.24 ± 8.70) ％],reduced cell growth inhibition [(27.25 ±0.75)％ vs.(10.96 ± 1.07)％] and apoptosis [(23.06 ± 1.43)％ vs.(10.65 ± 1.77)％].The result of Hoechst 33342 staining indicated that SOCS3 silence ameliorated the cell apoptosis induced by ONT.In addition,SOCS3 silence significantly improved pS6 expression at 2 weeks after injury,and mTOR and SOCS3 co-silence reduced cell viability,increased cell growth inhibition and apoptosis compared with SOCS3 silence group after injury.Conclusion SOCS3 silence promotes injury-induced cell viability of RGCs and suppresses injury-induced apoptosis of RGCs via up-regulating mTOR activity in the later period of injury.

Objective Linkage analysis were performed in 2 pure Chinese paroxysmal kinesigenic dyskinesia families to localize the locus of them. Method Microsatellites markers corresponding to pericentrometric region of chromosome 16 were used in parametric and nonparametrie linkage analysis for 27 members in the 2 pedigrees, haplotypes were constructed subsequently. Result The maximum LOD score and NPL score in the 2 families were all negative, P values were significantly larger than 0.05.No haplotype segregated with PKD phenotype was found. It showed no evidence of association with known PKD loci in both pedigrees, providing evidence for a novel PKD locus. Conclusion PKD is heterogeneous, a novel PKD locus may be in pure Chinese pedigrees.

Objective To investigate the functional changes of C3A cells co-cultured with pancreatic endothelial cells. Methods C3A cells and pancreatic endothelial cells lwere cultivated directly and indirectly for 7 days by the density ratio of 10: 1. Meanwhile, the blank control was established.The growth and morphological characteristics of experimental groups were observed. The out leakage level of AST, ALT and the synthesis level of albumin and the diazepam metabolism level were determined by automatic biochemistry analyzer, radioimmunoassay and enzyme linked immunosorbent assay. Results Direct co-cultivation of C3A cells and pancreatic endothelial cells could reduce the out leakage of ALT and AST in the 5th and 7th d. The capacity of albumin synthesis could reach 12. 977μg/ml on the 7th d and the that of diazepam metabolism could also be improved. Indirect co-cultivation of C3A cells and pancreatic endothelial cells could significantly raise the albumin synthesis to 7. 380 μg/ml and 10. 773 μg/ml on the 5th and 7th d, respectively. Conclusion Co-cultivation of C3A cells and pancreatic endothelial cells can significantly improve the basic biological function of C3A cells.
