Objective: To observe the recent efficacy, long-term survival and the side effects of low energy ultrasonic cavitation in treatment of 53 patients with solid tumors. Methods: Fifty-three patients with solid tumors were randomly divided into three groups: group A (18 patients received low energy ultrasonic cavitation therapy combined with chemotherapy), group B (18 patients received chemotherapy alone) and group C (17 patients received low energy ultrasonic cavitation therapy alone). Low energy ultrasonic cavitation therapy was administrated five days in one week for 2 weeks or three times each week for 3 weeks. Results: All fifty-three patients were included in the analysis. In group A, one case achieved complete response (CR), 6 cases achieved partial response (PR) and 9 cases achieved stable disease (SD); the disease control rate (CR+PR+SD) was 88.61% (16/18). In group B, no cases achieved CR, 4 cases achieved PR and 7 cases achieved SD; the disease control rate was 61.11% (11/18). In group C, no cases achieved CR, 4 cases achieved PR and 6 cases achieved SD; the disease control rate was 58.82% (10/17). The difference of disease control rate between groups A and B was significant (P<0.05). One-year survival rates of these three groups were 66.67%, 44.44% and 41.18%, respectively, and two-year survival rates were 38.89%, 16.67% and 17.65%, respectively. The one- and two-year survival rates in group A were both higher than those in group B and group C (P<0.05), but the difference was not observed between group B and group C. The proportions of patients with improved quality of life in groups A, B and C were 83.33%, 55.56% and 58.82%, respectively. There was no blood toxicity in group C. The major toxicities were local pain and fever, which could be self-relieved. Conclusion: Low energy ultrasonic cavitation therapy in treatment of solid tumors is efficient and well-tolerated, and the quality.

Objective To investigate the correlation between p21-actived kinase 1(PAK1) gene polymorphism and prognosis of endocrine therapy for breast cancer. Methods Polymerase chain reaction-restriction fragment length polymorphism was employed to analyze the genotype of PAK1 gene rs2298793 T→C polymorphism and rs2844327 C→T polymorphism of 105 patients with breast cancer accepting endocrine therapy. Prognostic factors such as age, state of menses, magnitude of tumor, pathological type, condition of operation, clinical stage, estrogen receptor, progesteron receptor, Her-2 and endocrine therapy drug were comprehensively considered, and Cox model was employed to analyze the relation of PAK1 genotype with the time-to-tumor progression (TTP). Results As to rs2298793C→T polymorphism, the TTP of CT genotype was shorter than TT genotype (P

Objective To study the effect of quercetin on proliferation and expression of P38MAPK and HMGB1 protein in neonatal rat cardiac fibroblasts induced by TNF-α.Methods Purified cardiac fibroblasts were obtained by trypsin digestion and differential adherence method.The proliferation of cardiac fibroblasts was detected by MTT assay.The expression of P38MAPK and HMGB1 protein was detected by Western blot.Results Quercetin had no effect on the proliferation of cardiac fibroblasts in the basal state but inhibited the proliferation of cardiac fibroblasts induced by TNF-α,and the A value of each group was increased with the increase of quereetin concentration(P＜0.05).The exspression of P38MAPK、HMGB1 were decresed with the icrease of quercetin.Conclusion Quercetin may inhibit the proliferation of cardiac fibroblasts induced by TNF-α.The mechanism may be inhibit the expression of HMGB1 through P38MAPK signaling pathway.

Objective To investigate the expression of estrogen receptor (ER), progesterone recptor (PR) and c-erbB-2 in breast cancer tissues and its relationship with prognostic factors. Methods The clinical data of 1 008 cases with breast cancer were retrospectively analysed. The relationship between the expression of ER, PR and c-erbB-2 in breast cancer tissues and the prognostic factors such as menopausal status, axillary lymph nodes metastasis and TNM stage was investigated. Results The mean presentation age of the 1 008 cases was (53.53?12.60) years. Invasive ductal cancer was the most common pathological type (80.5%). Postmenopausal ER-positive cases were significantly more than premenopausal ER-positive ones, and the clinical stage was lower (P

Objective To compare the safety of recombinant human tumor necrosis factor-Fc (rhTNFR:Fc) and other DMARDs,in patients with rheumatoid arthritis (RA),ankylosing spondylitis (AS),juvenile idiopathetic arthritis (JIA) or psoriatic arthritis (PsA).Methods Patients who received rhTNFR:Fc 25 mg twice weekly from May 2006 to March 2009 were involved in this open-lable study.Safety assessments were carried out at regular intervals.Results Of the 2014 patients enrolled in the open-label trial,1388,421 and 232 were RA,AS or other diseases,such as JIA and P.sA respectively.Frequent adverse events included injection-site reactions (2.67％),rash (1.87％) and hyperamino transferase (1.80％) in RA patients.Similarly,injection-site reactions (5.23％),hyperaminotransferase (2.38％) and rash (0.71％) were frequent in AS patients.Upper respiratory infection was most frequent among infectious adverse events.There were no reports of patients with serious adverse events,dead case,TB infection and malignancies.Conclusion rhTNFR:Fc has shown a favourable safety profile in Chinese rheumatic disease patients.

Objective To investigate the expression of Oct-4 as a stem cell marker in gastric carcinoma tissues and its clinical significance. Methods From June 1996 to March 2006, 63 paraffin samples of gastric carcinoma tissues were obtained, and the expression of Oct-4 was examined by immunohistochemical staining. Another 58 normal tissues adjacent to gastric carcinoma and 10 normal gastric mucosa tissues were served as controls. The clinieopathologieal data of 63 patients with gastric carcinoma were retrospectively analysed, and their relationship with the expression of Oct-4 was analysed. Fifty of these 63 patients were followed up for 8 years, Kaplan-Meier method and Log-rank teat were employed to explore the correlation between Oct-4 expression and survival, and Cox Regression analysis was performed to evaluate the possibility of Oct-4 expression as an independent prognostic factor for gastric carcinoma. Results The positive expression rate of Oct-4 in gastric carcinoma tissues was 80.95% (51/63), significantly higher than that of normal tissues adjacent to gastric carcinoma (5.2%, 3/58) and normal gastric mucosa tissues (0) (P < 0.01). The expression of Oct-4 was positively correlated to the clinical stage of gastric carcinoma(P<0.01). There was no significant difference in the expression of Oct-4 among patients with different differentiation, age, and gender (P>0.05). Patients with higher expression of Oct-4 had significantly shorter survival time (P<0.05). The expression of Oct-4 was not significantly correlated with the prognosis of gastric carcinoma(RR, 0.554; 95% CI, 0.209-1.466). Conclusion The expression of Oct-4 is correlated with the clinical stage and survival time of patients with gastric carcinoma, however, it is not an independent prognostic factor for gastric carcinoma.

Objective To explore the causes of subclinical hypothyrodism in children and the effects of the interventional therapy with thyroixine on the course of it.Methods Two hundreds children with subclinical hypothyroidism were measured for thyroglobulin antibody(TGAb),thyroid microsomal antibody(TMAb) in the blood serum,examined by colord Dopplor ultrasonic,examined by fine needle aspiraton cytology of the throid and measured the rate of 131I absorbed by thyroid in order to find out the causes of the disease.Two hundreds cases were randomly divided into two groups on the base of the cause of diseases,treatment group 100 cases and control group 100 cases.The treatment group were treated by throxine 25-75 ?g/d and the therapeutic dosage were chosen with the normal value of free triiodothyronine(FT3),free thyroxine(FT4)and high sensitive thyrotropin(sTSH) in the blood serum .After one year thyroxine therapy were stopped.Thyroid function was examined 6 months later after stopping the thyroxine.Results Among all of the causes of subclinical hypothyroidism in children,Hasgumoto′s thyroiditis accounts for 56%,simple goiter accounts for 26%,antithyroid drug accounts for 6%,the lack of thyroxine substitution therapy on the hypothyroidism accounts for 5% and undefined causes accounts for 7% .The thyroid function could keep normal for 1 year with an alternative therapy with thyroxine on subclinical hypothyroidism in children.Half a year later after stopping thyroxine,the thyroid function turned normal in most of the children.There were obvious differences in the ratio of cure and the ratio of effectiveness between treatment group and control group (t=20.2,3.2 Pa

Objective To observe the shape and the hemodynamic changes of the left heart after transcatheter closure of atrial septal defects(ASD) using Amplatzer occluder.Methods Sixty-five subjects with secondum ASD underwent transthoracic echocardiography(TTE) at pre-operation,48～72 h post-operation and follow-up performed more than 3 months after operation in 45 patients.The dimension of ASD,the parameters of the pulse-wave Doppler spectrums of the blood flow at the aotic valves and inlet of the left ventricle were recorded.At each position,systolic,early diastolic velocities and intervals were measured,the mitral annular movement spectrum was acquired at the lateral site of mitral annulus in the apical four-chamber view,Tei index and Tei_(TDI) index were derived from these parameters.Results All the patients had been implanted one Amplatzer occluder under the guide of echocardiography successfully.The preload of the left ventricular volume in the end of the diastolic period was increased and the low hemodynamic situation of the left heart and systemic circulation were corrected after the operation immediately.Accordingly,at 48～72 h after the operation,the end diastolic diameter,the stroke volume and the ejection fraction of the left ventricle were significantly improved continuously.However,the movement of the posterior wall decreased significantly at 48～72 h post-operation.The peak velocity of systolic period and the early diastolic velocities of the left ventricle were increased,but the ejection time had no changes follow-up.The systolic function of the left ventricle highlighted,the whole diastolic time prolonged after the 3 months of the operation.Tei index,Tei_(TDI) index and the heart rate had no difference between pre-and post-operation.Conclusions The anatomic deformation was corrected by transcatheter closure of ASD with Amplatzer occluder,the pre-load of left ventricular increased and had significant effect on the morphology and hemodynamic situation quickly,the left ventricular systolic and the diastolic function improved.The pre-load change of left heart had no effect on heart rate.Tei index and Tei_(TDI) index were independent of the pre-load and present the heart-self function.
