Background and purpose:Heparanase is an endo?-D-glucuronindise that degrades the HS sdie chains of heparin sulphate proteoglycans in ECM,expressed in the human normal placenta and immune organ.Expression of heparanase significantly increases in many kinds of cancers,it plays a central and specific role in the regulation of tumor metastasis and invasion.This article evaluates the effect of heparanase gene on the proliferation,adhesion and invasion of human ovarian cancer cell line SKOV3 cells.Methods:Human ovarian cancer cell line SKOV3 was cultured in optimum medium and transfected with pCDNA3.0-HPA by Lipofectamine~(TM2000),and cells transfected with blank vector pCDNA3.0 were used as control.The expression of HPA mRNA,and HPA protein in SKOV3,SKOV3/neo,and SKOV3/HPA were detected by RT-PCR and immunohistochemical staining;cell growth kinetics and the ability of invading was detected by MTT and transwell-ECM methode;the ability of adhesion and separation among same cells were evaluated by cell-adhering and separating method;Flow cytometry was used to test cell cycle.Results:RT-PCR and immunohistochemical staining showed that over-expression of HPA mRNA and protein in pCDNA3.0-HPA transfected cells in comparison with that in the parental SKOV3 cells and the cells transfected with blank vector(P

Objective:To study the inhibitory effect of siRNA on Heparanase (HPA) expression in SKOV3 cells. Methods:Two pairs of 21 bp reverse repeated sequence targeting HPA RNA (spaced by 9 bp nueleotide) were synthe- sized and were cloned into plasmid PGenesil-1 to construct recombinant plasmid PGenesil-1(+)-HPA expressing 2 hair- pin siRNAs.The inhibition of HPA gene was detected by RT-PCR,real-time PCR and immunohistochemical staining after PGenesil-1(+)-HPA was stably transfected into SKOV3 cells.Results:The recombinant plasmid PGenesil-1(+)-HPA (expressing 2 hairpin siRNAs) was successfully constructed.RT-PCR,real-time PCR and immunohistochemical staining showed that there was a significant decrease in HPA mRNA and protein level in experimental group compared with those in control group.Conclusion:siRNA targeting HPA mRNA can specically suppress the expression of HPA gene in SKOV3 cells;RNA interference method provides a new way for studying the role of HPA and gene therapy of cancer.

Objective To characterize non-headache symptoms during the migraine attack phase in migraine patients. Methods We enrolled in the present investigation 71 patients with migraine with and without aura who had sought medical treatment in our department from January 2010 to January 2011. We used a self-made migraine questionnaire to investigate associations of the non-headache symptoms with the sociodemographic factors, subtypes, severities and attacks of the headache in the patients. Results There were no significant differences in the number of non-headache symptoms among patients with different ages, genders, education levels, subtypes, severities, mean attack frequencies per month (P＞0.05). The most frequently reported non-headache symptoms were nausea (87.3％),phonophobia (81.7％) and mood change (69.0％).The incidences ofphonophobia,sleep disorder and osmophobia were significantly higher in patients without aura than in patients with aura (P＜0.05).Conclusion Migraine attacks are often accompanied by a variety of non-headache symptoms of which the most frequently reported ones are nausea,phonophobia and mood change.Patients without aura tend to have more phonophobia,sleep disorder and osmophobia than those with aura.

OBJECTIVETo explore the objective special features and role of various indexes of treadmill exercise test (TET) in patients of coronary heart disease (CHD) caused angina pectoris with Qi-Yin deficiency syndrome (QYD) with or without accompanied phlegm and blood stasis syndrome (PBS), to provide references for preventing and treating CHD in clinical practice.

METHODSOne hundred and one patients, whose diagnosis measured to the diagnostic standard and the inclusion criteria of angina pectoris and CHD, were classified according to their TCM syndrome type to two groups, the QYD without PBS group (49 cases) and the QYD with PBS group (52 cases). TET was conducted on all the patients. The relative parameters were measured and compared.

RESULTSAs compared with the QYD without PBS group, in the QYD with PBS group, (1) the TET positive rate was higher; (2) total exercise time was lesser; (3) the maximal metabolic equivalent (Max MET) was lower; (4) the average depression of ST segment at the exercise endpoint of test (mV) was higher; (5) the time of ST segment depressed for 0.1mV (min) was longer; (6) the metabolic equivalent during ST-segment depressed by 0.1mV was shorter; and (7) the change of QRS wave time-limit before and immediately after TET was more evident. Moreover, in the testing time more patients revealed angina episode after exercise, and less patients had their heart rate reached the requirement in the QYD with PBS group than those in the QYD without PBS group. Comparison between the two groups in all the above-mentioned indices showed significant difference respectively (P < 0.01 or P < 0.05).

CONCLUSIONPatients with CHD caused angina pectoris of QYD with PBS are worse in the tolerance for exercise and severer in pathological change of coronary artery than those in those without PBS, they belong to the severe phase of TCM syndrome.

Objective:To observe the clinical effects of aligned needling therapy for lumbar intervertebral disc herniation (LIDH).
Methods:A total of 80 cases with LIDH in conformity with the inclusion criteria were randomly divided into a treatment group or a control group by their visit order, 40 cases in each group. The points from the Governor Vessel, L1-L5 Jiaji (EX-B 2) points, from the first lateral line of the Bladder Meridian, Huantiao (GB 30), Weizhong (BL 40) and Yanglingquan (GB 34) were selected for acupuncture in the treatment group. Shenshu (BL 23), Dachangshu (BL 25), Ashi (Extra) points and Weizhong (BL 40) were used for routine acupuncture in the control group. The clinical effects of the two groups after 2-course treatments and recurrence rates three months later were observed. The pain severity before and after treatments was assessed by visual analog scale (VAS). The improvement of the patient’s pathological situation was evaluated by the performance assessment of lumbar disease treatment from Japanese Orthopedic Association (JOA).
Results:After the treatment for two courses, there was no dropped-out case in the two groups. The curative rates and total effective rates were respectively 32.5% and 92.5% in the treatment group versus respectively 12.5% and 82.5% in the control group. The differences in the curative rates and total effective rates between the two groups were statistically significant (bothP<0.01). After the treatment, VAS and JOA scores remarkably declined in the patients of the two groups, with statistical differences in comparison with those of the same group before treatment (bothP<0.05). In follow-up check of three months, the recurrence rate was 10.7% in the cured and remarkably effective cases in the treatment group and was 29.4% in the control group. The recurrence rates of the two groups were statistically different (P<0.05).
Conclusion:The aligned needling technique is remarkable in the clinical effects, obvious in the analgesic effects and low in the recurrence rate in the treatment of LIDH.
