Objective To evaluate the efficacy and toxicity of weekly docetaxel and cisplatin in previously untreated patients with advanced non-small-cell lung carcinoma. Methods Between January 2002 and December 2003 ,34 patients with pathologically comfirmed advanced non-small-cell lung carcinoma who had not received treatment were enrolled. The mean age was under 66 years. The patients received intravenous infusions of docetaxel(25 mg/m2,dayl ,8,15) with dexamethasone premedication and cisplatin(25 mg/m2,dayl ,8,15) ,followed by a week of rest. The remedies which were less than 6 regimens lasted to disease progression or severe toxicity. Therapeutic effect was evaluated by CT scan every two courses . The patients were followed up for 24 months. Descriptive statistics and SPSSIO. 0 software were used to analyse the results. Results 34 patients finished 90 courses. The mean was 2. 6 courses. All patients were followed up. Two patients achieved complete responses, ten patients achieved partial responses, ten patients achieved stable disease. An objective response rate of 35. 29% (95% confidence interval 19. 25%-51. 33% )was obtained. Patients life quality was significantly improved. The median time to progression was 4. 1 months, and median overall survival was 11 months. The 1-year survival rate was 47. 06% , the 2-year survival rate was 11.76% . Toxicities were mild. Grade 3 to 4 neutropenia (11.76%), anemia (5.88%), hyponatremia (5.88%), alopecie (17.64%) and nausea/vomiting (5. 88% ) were observed. Conclusion Weekly Cisplatin plus docetaxel is an effective and well-tolerated regimen in chemo-naive patients with advanced NSCLC. Well-designed clinical trials should be conducted.

Objective:To observe the effect of thoracic infusion of pseudomonas aeruginosa injection in malignant pleural effusion. Methods:A total of 90 patients with malignant pleural effusion were randomly divided into treatment group (31 cases),control group A (29 cases) and control group B(30 cases). Treatment group was treated with pseudomonas aeruginosa through intrathoracic infusion. Control group A and B were respectively treated with cisplatin and interleukin-2 through intrathoracic infusion. The clinical efficacy and adverse reaction were compared among the three groups. Results:The total effective rate of treatment group was 80.6%,the total effective rates of the control group A and B were 51.7%and 56.7%respectively.Compared with that of contral groups, the total effective rate of treatment group was higher, and the differences were statistically significant (P<0.05). The incidence of serious side effects and toxicity was lower in treatment group than in control groups. Conclusion:The effect of thoracic infusion of pseudomonas aeruginosa injection for malignant pleural effusion is significant, and the adverse reaction is mild. Thus it is worth to be promoted clinically.

Objective To assess the continent diversion results of sigma rectum pouch after radical cystectomy. Methods The reconstruction of bladder with sigmoid was modified for treatment of 18 cases of bladder tumor.The intestine was incised over a length of 20～24 cm with the junction of sigmoid colon and rectum as the midpoint so as to create a low pressure reservoir for urine and side-to-side anastomosis was performed on the posterior borders of the rectosigmoid wall.Submucosal tunnel modified technique was em- ployed in antireflux urethral implantation,Urination has been controlled by anal sphincter.Results About 80 minutes was spent to finish a new low pressure pouch after radical cystectomy.Among 18 patients with this op- eration,the controlled emiction were good after pull out the anal duct and"J"stent in 1 week to 2 months.Af- ter 2 months,the times of urination is stable,4～5 times in daytime and 1～3 times during nighttime.Two pa- tients had nocturnal enuresis and the symptom vanished after 2 months. One patient had adhesive ileus, two patients had hyperchloremia acidosis and kaliopenia,one patient had urethral stump cancer.There is no com- plication as anastomotic block,renal function lesion and severe upper urinary tract infection. Conclusion This operative method was easy,emiction control was well,and with higher quality of life for patients.It is al- so a better alternative diversion procedure that would be easily accepted.

Objective To explore the effect of L-carnosine on neuronal cell apoptosis in young rats with experimental febrile seizures(FS).Methods Forty 15-day SD rats were randomly divided into intervention group(n=30)and FS group(n=10).Warm water was used to induce 10 times FS.The intervention group was divided into E,G and H group,10 rats in each group.Intraperitoneal injection of L-carnosine(250 mg/kg)was separately given to the rats in E group,G group and H group respectively after 30,60 and 120 min of seizure.FS group were induced FS,but they were not given intervention.The rats were sacrificed at 12 hours after the last seizure.Neuronal cell apoptosis was determined by terminal eoxynucleotidyl transferase-mediated dUTP nick end labeling(TUNEL)in situ cell death kit.TUNEL positive cells were stained and counted as apoptosis in hippocampus and cortex.Ultrastructural changes of apoptosis neurons were observed under the electron microscope.Results The neuronal cells apoptosis count was 25.37?1.95 in FS group,12.36?1.13 in E group,17.85?2.04 in G group,and 22.69?2.69 in H group.Neuronal apoptosis of FS group was apparently higher than that of interventional groups(F=10.75 P0.05).Under the electron microscope,neuronal damage on hippocampal CA1 area and dentate gyrus of FS group and H group was obviously higher than that of E group.Conclusions Early injection of L-carnosine would not only relieve neuronal apoptosis of repeated FS,but also play a role in the protection of neuronal cells.

BACKGROUND: The surface electromyography can evaluate the effect of exercise by recording the parameters of muscle activities, and vibration exercise is the best supplement to traditional weight training. More research focuses on the effect of simple vibration training on the surface electromyography of lower limbs, but the influence of vibration combined with weight-bearing training is poorly understood.OBJECTIVE: To study the effect of vibration combined with load on the surface electromyography of lower limbs at the micro level of muscle working principle.METHODS: Eight healthy college students were recruited, and subjected to four different stimulations: vibration (45 Hz) combined with load (45% one repetition maximum (IRM)); vibration (45 Hz) combined with load (60% 1RM); vibration (50 Hz) combined with load (45% 1RM); vibration (50 Hz) combined with load (60% 1RM), followed by semi-squat exercise with the heel lifting, 10 times/minute, for 3 courses with more than 2 hours in between.RESULTS AND CONCLUSION: Different vibrations combined with loads made significant difference on the root mean square amplitude of the surface electromyography (P < 0.01), and there was a significantly increased root mean square amplitude in the vibration (50 Hz) combined with load (45% 1RM), especially at the medial gastrocnemius. The four kinds of stimulations made significant different effects on the surface electromyography of rectus femoris, tibialis anterior, and medial gastrocnemius, except semitendinosus (P ≤ 0.05). Moreover, the effect showed significant difference among different stimulations except vibration (50 Hz) combined with load (45% 1RM) (P ≤ 0.05). Compared with the other three stimulations, vibration (50 Hz) combined with load (45% 1RM) exerted better effect on the muscular activation. To conclude, different vibrations combined with loads exert different effects on the motor unit of same neuromuscular activity, and a suitable stimulation may produce better effect. Besides, the same stimulus for the motor unit of different neuromuscular activities produces different effects, which may match to the muscle nature.

Objective To explore the feasibility and clinical efficacy of long-segmental bone defects after en bloc tumor resection of lower limb segment with composite of titanium alloy 3D printed prosthesis and vascularized fibular autograft and bioceramics.Methods 5 patients with lower extremity tumor (1 high grade chondrosarcoma,1 Ewing sarcoma,1 single metastatic tumor and 2 osteosarcoma) were treated by en bloc resection and precise reconstruction with segmental 3D-printed,custom-made prosthesis from August 2015 to November 2016,which composed of 1 male and 4 females,ranged from 16 to 56 years old,the average was 32± 19.3 years old.Three-dimensional computed tomography reconstructed images of patients' tumors were built before surgery.Custom-made prostheses were manufactured based on the patients' reconstructed images with micro-pores on the surface.After en bloc tumor resection with the help of osteotomy guide plate,the defects were reconstructed with 3D-printed,custom-made prostheses.Vascularized fibular autografts were put inside the prostheses,and the interval space among them was filled with bioceramics.Results All the 5 cases were performed surgical planning before the surgery with prosthesis and guide plate were designed at the same time.After verification of the finite element analysis SLM (2 cases) and the EBM (3 cases) were used to process prosthesis,and were designed into porous sharp with 210.98±66.16 mm in length and 26 901.76±12 903.96 mm3 in volume.Then the prosthesis would be cleaned and sterilized.All 5 operation were proceeded according to the plan of preoperative.The intra-operative guide plate were installed on the bone surface stably.The bone cutting was guided according to the plan of preoperative.By intra-operative frozen pathological examination,there were no malignant tissues in near and far marrow cavity.Unfolded fibular flap with 168.75±49.07 mm in length and porous tricalcium phosphate particle composite implants with 10±4.08 g were used in 4 cases and bone cement was used in 1 cases of metastatic tumor.The average operation time was 261±85 min and average blood loss was 540±182 ml.After a mean follow-up time of 6.4 months (1-15 months),all 5 cases survived with no local recurrence and pulmonary metastasis tumor.2 cases with vascular pedicle fibular transplant confirmed the survival of fibula via bone scan 3 months after operation.All cases were no infection,fractures,prosthesis loosening,except broken screw in 1 case.The Musculoskeletal Tumor Society (MSTS) 93 score was 17-26.Conclusion Long segment tubular titanium alloy 3D printed prosthesis with vascularized fibular autograft and bioceramics could reconstruct the segmental defects caused by tumor resection.
