Objective: To evaluate the efficacy and toxic reactions of Endostar combined with TP chemo-therapy in the treatment of advanced stage non-small cell lung cancer (NSCLC). Methods: A total of 68 cases of advanced stage NSCLC confirmed by pathohistology or cytology were randomly divided into two treate-ment groups: the Endostar combined with TP chemotherapy group (37 cases) and the simple TP chemothera-py group (31 cases). Patients in the Endostar combined with TP chemotherapy group were treated with TXT 65mg/m~2 on d2 and d9, DDP 75 mg/m~2, d1-4; and endostar 15g, d1-14. Patients in the simple chemotherapy group were treated with TXT and DDP. After 2 weeks, we estimated the recent curative effect and toxic reac-tions according to WHO standard. Results: The total response rates in the two groups were 56.8% and 29.7%, respectively, with a significant difference (X~2=4.08, P<0.05). The main toxic reactions were bone marrow sup-pression, gastrointestinal reactions and hair loss. And the incidences of the above three toxic reactions were 59.4%, 39.1%, and 81.1% in the endostar combined with chemotherapy group and 64.5%, 38.7%, and 83.9% in the simple chemothotherapy group. The toxic reactions were mainly related to chemotherapeutics and were not significantly different between the two groups (P>0.05). Conclusion: Endostar combined with chemothera-py is a safe method to treat advanced stage NSCLC. Endostar can improve the curative effect of chemothera-py. This method deserves to be clinically practiced and observed further.

To investigate the effects of Tongxinluo capsule on sciatic nerve apoptosis in spontaneous type II diabetic KK/Upj-Ay mice, in order to explore its mechanism for improving diabetic peripheral neuropathy (DPN). KK/Upj-Ay mice were selected as the DPN animal model and randomly divided into the model, Tongxinluo low, middle and high group (1, 2, 4 g x kg(-1)). C57BL/6 mice were selected as the control group. Mice were given intragastrically for 12 weeks. Paw withdrawal latency, motor nerve conduction velocity (MNCV) and sensory nerve conduction velocity (SNCV) were detected. Apoptotic rate were detected by FCM. Bcl-2, Bax, Caspase-3 mRNA and protein expression in sciatic nerve were examined by Real-time PCR and Western blot. p38MAPK, p-p38MAPK expression were examined by Western blot. In this study,the authors found that Tongxinluo capsule could increase paw withdrawal latency, MNCV and SNCV. Apoptotic rate of sciatic, the expression of Bax and caspase-3 were lower, while Bcl-2 expression was higher in Tongxinluo group than those in model mice. The expression of p-p38MAPK significantly decreased in Tongxinluo group. The results showed that Tongxinluo capsule has protective effects on diabetic peripheral neuropathy of mice via inhibiting cell apoptosis and suppressing the expression of p-p38MAPK.

Objective To study the therapeutically effect of rAAV-TIE model in vivo. Meth-ods Cell suspensions of T24 cells were injected into the subcutaneously of right scapular region of nude mice. The nude mice were raised under SPF condition and the xenograft tumor growth was ob-served. Bearing tumor nude mice were randomly divided into 5 groups: rAAV-MCS group, rAAV-Tk group, rAAV-ES group, rAAV-TIE group and control group. Four weeks later of treatment, the nude mice were sacrificed. The xenografts tumors were fixed for HE staining. The liver tissue and ne-phridial tissue were also fixed for HE stain. The blood sample and endostatin concentration was as-sayed by ELISA. Results After 3 weeks of injected with T24 cells on nude mice, 25 showed visible tumor on the injected location. The rate of tumor formation was 93%. After 9 days injected by rAAV-ES, rAAV-TK, rAAV-TIE, the tumor volume were: rAAV-ES group(0.75±0.08)cm3 , rAAV-TK group(0.71±0.11)cm3 , rAAV-TIE group(0.52±0.09)cm3 , rAAV-MCS group(1.27±0.13)cm3 and control group (1.24±0.17)cm3. The microvessel density in the different groups were as follow-ings: rAAV-ES group(18.72±2.53)/HP, rAAV-TK group(21.74±4.62)/HP, rAAV-TIE group (12.73±1.78)/HP, rAAV-MCS group(52.38±6.46)/HP and control group(49.94±7.17)/HP. The endostatin concentration in the diffcrent groups were as followings: rAAV ES group(38.52 6.53)μg/L and rAAV-TIE group(40.33±7.48)μg/L. HE staining confirmed the tumor. The liver tissue and kidncy tissue of each group had no obviously cell degeneration or necrosis. Conclusion The rAAV-TIE could inhibit tumor induced angiogenesis and suppress both the initiation and the subse-quent growth of human bladder cancer in nude mice model.

Objective To assess the efficacy of the laryngeal mask airway i-gel (LMA i-gel) in patients undergoing neuro-interventional surgery. Methods Forty ASA Ⅰ or Ⅱ patients of both sexes, aged 20-60 yr,body mass index ＜ 30 kg/m2, undergoing elective neuro-interventional surgery, were randomized into 2 groups (n = 20 each):LMA i-gel group (group I) and LMA ProSeal group (group P). After induction of anesthesia with TCI of propofol and remifentanil, LMA i-gel and LMA ProSeal were inserted in group I and P respectively. The patients were mechanically ventilated and PETCO2 was maintented at 35-40 mm Hg,SpO2 at 99%-100%. BP and HR were monitored and recorded before induction, immediately after induction, at 1, 3 and 5 min after insertion of LMA and immediately after removal of LMA. The success rate, LMA placement time, leak pressure, peak airway pressure and complications were recorded. Results There was no significant difference in the success rate, the LMA platcement time and peak airway pressure between the two groups (P ＞ 0.05). BP and HR were within the normal range during operation in both groups. The leak pressure and incidence of blood stain and sore throat were significantly lower in group I than in group P (P ＜ 0.05). Conclusion LMA i-gel can provide adequate ventilation during operation with less complications and can be used effectively for neuro-interventional surgery.

Lamellar bodies, tubular and lattice myelin figures (TMF and LMF)of the Type Ⅱ epithelial cells lavaging from the lungs of adult male rats following injection of a single dose of 10mg of active carbon powder, silica dust, uranium ore dust and U_3O_8 powder were observed by scanning and transmisson electron microscope as well as freeze-etching technique. According to the membrane split theory and our observations, we suggested that the lamellar bodies were composed of a lot of subunits, the square crystalls. These crystals linked up each other to form a cuboidal structure and arranged regularly into ring-like lamellae. A central core was surrounded by the lamellae to constitute a lamellar body, which can be distingushed into three types, namely the wollen ball-shaped, the circular concentric shaped and the lattice-shaped. When the circular concentric lamellar bodies were dissociated from the type Ⅱ epithelial cells, they then extended to form the pulmonary surfactant system (LMF). The amount of the pulmonary surfactant system substances in the rats administrated the above-mentioned foreign substances was obviously higher than that of controls.

Objective To evaluate the efficacy and safety of open occluded coronary artery branch through outside stent balloon expansion technique.Methods A retrospective analysis of 26 patients,26 interventional treat-ment of coronary bifurcation lesions were taken.All patients initially used conventional interventional techniques, branch reserve protection guidewire and main branch stent.When branch occlusion occured during operation and failed again through guidewire,small outer diameter of the balloon branch guidewire which was squeezed could be used to branch opening.The blocked branch opening was expanded outside of the stent,and the balloon was expanded after the guide wire enter into branch again.The main branch/branches kissing balloon inflation or main branch /branch double stenting would be used when necessary.Results Among 26 cases of bifurcation branch occlusion,25 cases successfully completed the outer stent balloon,achieved a branch balloon expansion after reentry guidewire,saved blocked branches and the rate of success was 96.2%,and 6 cases of the main branch and the branch kissing balloon dilatation,2 cases of remedial double stenting.Following -up for 1 -12(5.3 ±6.8)months after operation in 25 cases of patients,there was no death and myocardial infarction and other adverse cardiovascular events.Conclusion Out-side stent balloon expansion technique can improve the success rate of coronary occlusion branch opening,and it have fewer complications and worth of clinical application becasuse of its satisfactory results.
