Objective To evaluate the hemodynamic changes induced by local infiltration with different concentrations of adrenaline during endoscopic sinus surgery under general anesthesia using impedance cardiography (ICG) .Methods Sixty-nine ASA Ⅰ or Ⅱpatients of both sexes (37 males, 32 females) aged 18-60 yrs undergoing elective endoscopic sinus surgery under general anesthesia were randomized to receive local infiltration of nasal mucous membrane with 4 ml of lidocaine containing 20 ?g (group Ⅰ) or 40?g (group Ⅱ) or no adrenaline (group Ⅲ-control) . Hemodynamic changes were monitored by ICG. MAR, HR, cardiac index (CI), systemic vascular resistance index (SVRI) and acceleration index (ACI) were recorded before (baseline) and at 0.75, 1.5, 2.25, 3.0, 3.75, 4.5, 5.25 and 6.0 min after local nasal adrenaline infiltration.Results MAP was significantly decreased while HR increased at 1.5 min after adrenaline infiltration as compared to the baseline values in group Ⅰ and Ⅱ (P

Objective Prostate cancer is one of the most common cancer in males .The article was to investigate the expres-sion and clinicopathological significance of VEGF-C mRNA in prostate cancer , finding the molecular marker for early diagnosis and prognosis assessment of prostate cancer . Methods TaqMan real-time polymerase chain reaction ( PCR) analysis was used to detect the expression of VEGF-C mRNA in 3 prostate cancer cell lines(PC-3, DU145 and LNCap), 32 cases of prostate cancer (Pca) sam-ples and 15 cases of benign prostatic hyperplasia (BPH).Analysis was also made on the correlations of VEGF-C mRNA expression, clinicopathological features and prognosis . Results High levels of VEGF-C mRNA were detected in PC-3 ( 153 .31 ±26 .24 ) and DU145(194.62 ±41.36)compared to LNcap(1.00 ±0.00).The expression of VEGF-C mRNA in prostate cancer tissues was 3.43 folds higher than that in the benign prostatic hyperplasia tissues ([13.67 ±1.95] vs [11.89 ±1.63], P=0.004).The high expres-sion of VEGF-C mRNA in prostate cancer was associated with high Gleason score ( P =0.004 ) and lymph node metastasis ( P =0.015).In patients with high expression and low expression of VEGF-C mRNA, the 3-year survival rate was 12.5%and 40.0%re-spectively(P=0.033). Conclusion The VEGF-C mRNA expression may be related to the biological behavior of prostate cancer .It is suggested that VEGF-C mRNA can be used as a prognostic marker for prostate cancer .

Objective To study the effects and mechanism of different administrations of atorvastatin on myocardial ischemia/reperfusion (MI/R) in rats.Methods A total of 160 male SD rats were randomly divided into five groups:sham group,MI/R group,atorvastatin of conventional dose (MI/R + N) group,atorvastatin of preoperative signal loading dose (MI/R+SL) group,and atorvastatin of preoperative continuous loading dose (MI/ R+ML) group.MI/R model was established in the rats.Myocardial infarction size was detected by Evans blue/ TTC staining.The activity of ATPase of cardiac muscle and the levels of serum IL-6 and TNF-α were detected by ELISA.The level of LVEF％ was detected by small animal ultrasound.Results Compared with MI/R+N group,MI/R+ SL and MI/R+ ML groups had significantly smaller myocardial infarction size (P＜0.05),higher activity of ATPase (P＜0.05),lower levels of serum IL-6 andTNF-α (P＜0.05),and more advancedLVEF％ (P＜0.05).However,MI/R+SL group and MI/R+ML group did not differ significantly in the above-mentioned parameters.Conclusion Atorvastatin of loading dose might alleviate MI/R injury by improving ATP metabolism of cardiac muscle and reducing abnormal expressions of inflammation factors.Meanwhile,the administration of preoperative continuous loading dose and preoperative signal loading dose of atorvastatin may not differ in protecting against MI/R injury.

Objective To investigate the ultrasound diagnostic value for nipple discharge disease by comparison with fiberoptic ductoscopy. Methods Fiberoptic ductoscopy and ultrasonic inspection were performed on fifty-seven patients with spontaneous nipple discharge,and the results were analysed. Results In all patients, 55 cases (96. 49 % ) were abnormal in high-frequency ultrasound inspection:27 mammary duct expansion(47.36%),19 occupying lesion with mammary duct expansion or cyst (33.33%),6 cystic echo ( 10. 52% ) ,3 only solid echopattern (5.26%) ,and 2 nothing found (3.51% ). In ultrasonic inspection,color and pulse Doppler signal were found in 7 cases. On the other hand, 26 galactophoritis (45.61%), 12mammary duct ectasia (21.05 %), 17 intraductal papilloma (29.82%), 2 breast carcinoma (3.50%) were diagnosed by fiberoptic ductoscopy. In all 19 cases with occupying lesion,ultrasonography's sensitivity was 52. 63% ,specificity was 89. 47%, misdiagnosis rate was 10. 50%, rate of missed diagnosis was 47.36%.Conclusions To nipple discharge disease, high-frequency ultrasound has high sensitivity, easy to find abnormal indication,but is not accurate enough in the diagnosis of smaller occupying lesion.

Objective To explore the effect of transcription factor E2F1 on the apoptosis of small cell cancer line H446. Methods Plamid vector- mediated E2F1 small hairpin RNA (shRNA) was used to silence E2F1 in H446 cell. RT-PCR and western-blot assay were used to detect the expressions of E2F1 and Bcl-2. The apoptosis rate in H446 cell line was detected by flow cytometry assay. Result E2F1 protein was suppressed in shRNA1-modified H446 cell. Sgnificant difference of the apoptosis was shown between E2F1 shRNA1 group and the other two groups. Additionaly, the expression of Bcl-2 protein increased in E2F1 shRNA1-modified cell line. Conclusions E2F1 is highly expressed in H446 small cell lung cancer cell line. E2F1 promotes apoptosis of H446 through upregulating Bcl-2 expression.

OBJECTIVE: To explore the mechanism of Tiaozhong Granule (TZG), a compound traditional Chinese herbal medicine, in treating rats with mixed reflux esophagitis. METHODS: Fifty-eight SD rats were randomly divided into untreated group (n=12), sham-operated group (n=10), TZG-treated group (n=12), Banxia Xiexin Decoction (BXXXD)-treated group (n=12) and cisapride-treated group (n=12). Mixed reflux esophagitis was induced by esophago-duodenum end-to-side anastomosis. Four weeks later, the rats were orally administered twice daily for 12 days. Pathological changes of esophagus mucous membrane were observed by using HE staining. The expressions of proliferating cell nuclear antigen (PCNA) and p53 in the esophagus tissue were detected by immunohistochemical SABC method. Spectrophotometric method was used to detect the content of malondialdehyde (MDA) and the activities of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) in serum. RESULTS: Compared with the untreated group, pathological changes of esophagus mucous membrane were relieved in different degrees in TZG-treated group, BXXXD-treated group and cisapride-treated group. Content of MDA and expressions of PCNA and p53 were obviously decreased in the three treated groups (P<0.01), and the activities of SOD and GSH-Px were significantly increased in the three treated groups (P<0.05, P<0.01). TZG had better effects than cisapride in decreasing the content of MDA and increasing the activities of SOD and GSH-Px (P<0.05). TZG was better in aspect of reducing the expressions of PCNA and p53 than BXXXD and cisapride tablets (P<0.05). CONCLUSION: Tiaozhong Granule can treat mixed reflux esophagitis in rats, and its action mechanisms may be associated with decreasing the expressions of PCNA and p53 in esophagus mucous membrane, reducing the content of MDA and increasing the activities of SOD and GSH-Px in serum.

BACKGROUND:Knee osteoarthritis is characterized by inreversible pathological changes, belonging to arthragia syndrome. The goal of the treatment is to release or relieve symptoms and delay joint degeneration. Jianxi Qianggu Pil is an empirical formula developed by the Third People’s Hospital of Jingzhou, School of Basic Medical Science, Wuhan University, China. This prescription can nourish liver and kidney, eliminate wind and disperse cold, expel wet and dredge the col aterals, consolidate bone and reinforce knee.
OBJECTIVE:To observe the protective effect of Jianxi Qianggu Pil on joint cartilage and expression of bone morphogenetic protein 7 in rabbits with knee osteoarthritis.
METHODS:A total of 36 New Zealand rabbits were randomly divided into three groups, with 12 ones in each. The involved rabbits were applied to establish the model of knee osteoarthritis by using the modified Hulth’s method. At 6 weeks after modeling, the drug group was given 0.1 g/kg Jianxi Qianggu Pil via intragastric administration, while model group and normal control group received equal volume of saline. At 4 weeks after drug administration, rabbit articular cartilage was evaluated with Mankin’s scoring method. The cartilage morphology was observed under electron microscopy, and bone morphogenetic protein 7 expression was detected using immunohistochemistry.
RESULTS AND CONCLUSION:The pathological degeneration degree of articular cartilage in the drug group was significantly lighter, and bone morphogenetic protein 7 expression was significantly higher than the other two groups (P<0.05). Experimental findings indicate that, Jianxi Qianggu Pil can promote the expression of bone morphogenetic protein 7 in articular cartilage of knee osteoarthritis rabbits, thereby promoting articular cartilage regeneration and reducing cartilage deformation or necrosis for the treatment of arthritis.

Objective To investigate the clinical effects of transurethral resection of cystitis after gynecological cystitis after transurethral resection of bladder,and to observe the effect on patients' anxiety(SAS)and quality of life index(QOL).Methods The clinical data of 62 patients with cystitis glandularis admitted to hospital from January 2011 to December 2016 were retrospectively analyzed.The control group was treated with plasma ablation alone,with plasmakinetic resection of Kangfuxin liquid combined with gemcitabine intravesical therapy as the treatment group,31 cases in each group.Statistics of two groups of patients with clinical efficacy,followed up for 12 months,and the anxiety self-rating scale(SAS)was used to evaluate the anxiety of the two groups before and after treatment,QOL was used to evaluate the quality of life before and after treatment in two groups of patients.The recurrence rate of two groups were recorded.Results After treatment,the effective rate of the treatment group was 80.65％,slightly higher than the control group 77.42％,the difference was statistically significant(P<0.05),the SAS score in the treatment group was slightly higher than before treatment,but the difference was not statistically significant,the SAS score in the control group was significantly lower than before treatment,after treatment between the groups,the difference was statistically significant(P<0.05).The QOL index of the treatment group decreased slightly after treatment,but the difference was not statistically significant.The QOL index of the treatment group decreased significantly after treatment,and compared between the two groups after treatment,the difference was statistically significant(P<0.05).Follow-up of 12 months,the relapse rate in the treatment group was 11.11％,slightly lower than the control group 18.75％,the difference was statistically significant(P<0.05).Conclusion Compared to pure plasmapheresis,the use of postoperative intravesical instillation of bladder irrigation with the same effect,but the latter may increase the degree of anxiety in patients,thus affecting the quality of life of patients,so for the non-mandatory use of drugs treatment,surgery may be given priority to surgery alone.

Objective To explore main technical points and clinical efficacy of individualized stepwise multiple embolization treatment for refractory hemoptysis. Methods To retrospectively analyze materials of 103 patients treated by individualized stepwise multiple embolization. According to disease categories, individualized stepwise multiple embolization treatment with polyvinyl alcohol and loaded sodium alginate microspheres as basic embolization agent were performed, after the type, number, abnormal branches, pulmonary circulation and systematic pulmonary shunt of targeted vessels were confirmed through radiography. To judge short(less than 3 months), medium(3 to 6 months) and long term(more than 6 months) efficacy, resolution of hemoptysis after operation were assessed. To evaluate efficacy of individualized stepwise multiple embolization treatment for refractory hemoptysis, Kaplan-Meier survival curves were used. According to the features of target vessels to supply blood, patients were classified into with SPS and without SPS. By using Log-Rank test, the effective rates of one-year were compared between them. Results Out of 103 patients, 215 target vessels were demonstrated, among which individualized stepwise multiple embolization was for 196 target vessels, peripheral embolization for 8 vessels, and main trunk embolization in 11 patients. The visits after operation were made to 103 patients after 6 to 50 months, with the medium of 21 months. Hemoptysis was instantly resolved in 97.1%(100/103). The effective rates were 94.5%,93.2%, 89.7%,88.9%,85.2%and 76.6%for one, three, six months and one, two and three years after operation. In 103 patients, patients with SPS were 22 and without SPS were 81. One-year effective rates with and without SPS were (69.50 ± 0.11)% and (98.30 ± 0.03)% , respectively (χ2=11.662,P<0.01). Conclusion Individualized stepwise multiple embolization treatment shows excellent short-term and mid-long term efficacy in the treatment of refractory hemoptysis.
