Objective To study the use of fiberoptic bronchoscope in the positioning of double-lumen endobronchial tube in Chinese patients. Methods Ninety ASA Ⅰ - Ⅱ patients (60 male and 30 female) undergoing thoracic surgery requiring one-lung ventilation were enrolled in the study. Age ranged from 14-79 years (mean age 56 ?16) and the average height was 169? 6 cm (male) and 158?6 cm (female) respectively. Anesthesia was induced with fentanyl, propofol and vecuronium. Double-lumen endobronchial tube (Broncho-Cath, Mallincrodt Medical) was inserted following conventional procedure. Proper position of double-lumen tube(DLT) was determined by auscultation. Fiberoptic bronchoscope was made if needed. The fiberoptic bronchoscopy was repeated after lateral decubitus positioning of the patient. The depth of the tube inserted was recorded. Results The fiberoptic bronchoscopy revealed that the incidence of malpositioning of the left-sided DLT was 68% and of right-sided DLT was 62% . The most common malposition was that the tube was placed too deep. The dislodgement of DLT in lateral decubitus positioning of the patient occurred in 24% patients and in most cases the DLT was moved upward. The depth of insertion did not correlate with the patient' s height. Conclusion Fiberoptic bronchoscopy is a reliable technique for correct positioning of DLT and should be used routinely.

Objective To determine the effective target plasma concentration required to prevent tracheal intubation in 50% of patients (Cp50) anesthetized with propofol by TCI.Methods Twenty ASA Ⅰ or Ⅱ patients aged 18-45 yrs with body mass index

Objective To investigate the efficacy of ultrasound?guided iliohypogastric∕ilioinguinal nerve block and transversus abdominis plane block for analgesia after cesarean section. Methods Ninety parturients, aged 20-40 yr, of American Society of Anesthesiologists physical status Ⅰ or Ⅱ, scheduled for elective cesarean section, were divided into 3 groups ( n=30 each) using a random number table:con?trol group (group C), ultrasound?guided iliohypogastric∕ilioinguinal nerve block group (group IH∕II) and ultrasound?guided transversus abdominis plane block group (group TAP). In IH∕II and TAP groups, bilat?eral ultrasound?guided iliohypogastric∕ilioinguinal nerve block and transversus abdominis plane block were performed after surgery, respectively, with 0.5% ropivacaine 1.5 mg∕kg ( the maximal dose 100 mg) plus dexamethasone 5 mg for each side. All the patients received patient?controlled intravenous analgesia with morphine after surgery, and numeric rating scales scores at rest and during movement were maintained<4 within the 48 h after surgery. The cumulative consumption of morphine was recorded at 6, 12, 24, 36 and 48 h after surgery. The occurrence of adverse reactions such as nausea, vomiting, pruritus, over?sedation and respiratory depression was observed and recorded in the analgesic period. Results Compared with group C, the cumulative consumption of morphine was significantly decreased at each time point in IH∕II and TAP groups ( P<0.01) . Compared with group IH∕II, no significant change was found in the cumulative consumption of morphine at 6 and 12 h after surgery, and the cumulative consumption of morphine was sig?nificantly increased at 24, 36 and 48 h after surgery in group TAP ( P<0.05) . No nausea, vomiting, pru?
ritus, over?sedation and respiratory depression was found in IH∕II and TAP groups. Conclusion For par?turients, ultrasound?guided iliohypogastric∕ilioinguinal nerve block and transversus abdominis plane block both can provide analgesic efficacy after cesarean section, and the efficacy of the former one is better.

Objective To explore the morbidity,the diagnosis and the method of therapy of accidental prostatic carcinoma. Methods From Jan of 1984 to May of 2004, 19 cases of prostatic accidental carcinoma were confirmed on pathological examination after prostatectomy for BPH. Bilateral orchiectomy and Estrogen treatment were performed in 6 cases and Bilateral orchiectomy in 7 cases alone but no treatment in 6 cases. Results 5 of the patients wereA1 stage and 14 A2 stage. 12 of them were followed up for 3 to 120 months. 14 of them survived and one untreated died of metastasis to pubis and vertebra after one year. Conclusions Most patients of prostatic accidental carcinoma are A1 and have a better prognosis. Bilateral orchiectomy and Estrogen treatment might improve the patients’s survival rate.

This thesis found the female homicide cases present its own characteristics because of differences in psychological, physiology characteristics, character between males and females through the statistical analysis of age distribution, the relationship between criminal suspects and victims, the classification of crime scenes, injury tools and the mortal wound positions of 116 female homicide cases in Lianyungang between 1993 to 2014. Mostly, the relationship between criminal suspects and victims is family, especially couple or valentine; the crime scenes are frequently indoor, especially bedrooms. They always choose production and life tools when victims are in deep sleep or drunk time to make the victims asphyxia, posioning or drowning. The injuries focus on vitals and usually hit many times lead to mortal wound, agonal trauma and postmortem injury.

Objective To evaluate the effects of sufentanil on regeneration and repair after single sciatic nerve injury in mice. Methods Seventy?five healthy male BALB∕c mice, aged 6-8 weeks, weig?hing 18-22 g, were divided into 5 groups ( n=15 each) using a random number table: peripherial nerve injury group (group PNI), low, medium and high doses of sufentanil groups (L, M and H groups) and cyclosporine A group ( group C) . The model of unilateral sciatic nerve transection was established in the 5 groups. In L, M and H groups, sufentanil 2?5, 5?0 and 10?0 μg∕kg were injected intraperitoneally, re?spectively, once a day for 3 consecutive days. Cyclosporine A 50 mg∕kg was injected intraperitoneally once a day for 3 consecutive days in group C. The equal volume of normal saline was given once a day for 3 con?secutive days in group PNI. Neurophysiological monitoring was performed at 4, 8 and 12 weeks after opera?tion, the amplitude of compound muscle action potentials of the sciatic nerve was recorded, and the nerve conduction velocity was measured. At 8 weeks after operation, 5 mice were sacrificed, the sciatic nerve 0?5 cm of the upper and lower the anastomosed site was removed for examination of the morphology of myelin sheath with light microscope, and the number of nerve fibers was calculated. Results Compared with group PNI, the amplitude of compound muscle action potentials of the sciatic nerve, nerve conduction ve?locity and the number of nerve fibers was were significantly increased in M, H and C groups ( P<0?05) , and no significant change was found in the parameters mentioned above in group L ( P>0?05 ) . Myelin sheath arrangement was severely irregular, and more vacuoles were found in group PNI. Myelin sheath ar?rangement was irregular, and more vacuoles were found in group L. Myelin sheath arrangement was mainly regular, and vacuoles were found occasionally in group M. Myelin sheath arrangement was regular, and no vacuoles were observed in H and C groups. Conclusion Sufentanil can promote regeneration and repair af?ter peripheral nerve injury in mice.

Objective To investigate the effects of sufentanil on activation of spinal astrocytes in mice after unilateral sciatic nerve injury.Methods Eighty healthy male BALB/c mice,aged 6-8 weeks,weighing 18-22 g,were randomly divided into 4 groups (n=20 each): sufentanil high dose group (group H),middle dose group (group M),low dose group (group L) and model group (group MO).After model of sciatic nerve injury was established by unilateral sciatic nerve transection,group H,M and L,sufentanil 10 μg/kg,5 μg/kg,2.5 μg/kg was injected intraperitoneally once a day continuously for 3 days,while the equal volume of saline was injected in group MO.Five mice in each group were selected,and the sciatic nerve functional index were measured at 4,8,12 weeks.The 5 mice were sacrificed from each group and the damage on the same side L4-L6 segments of the spinal cord were removed at 2,4,8,12 weeks.The pathological changes were examined under light microscope at 8 week point.The expression of GFAP was determinatied at each time points by immuno-histochemistry.Results Compared with group L and MO,sciatic nerve functional index significantly was increased in groups H and M (P<0.05),and no significantly change was found in group L.Spinal cord neurons had a better morphology in groups H and M than in group L and MO.Compared with group MO,The expression of GFAP were significantly up-regulated in groups H,M and L (P<0.05).Compared with group L,the expression of GFAP were significantly up-regulated in groups H and M (P<0.05).Conclusion Sufentanil promotes spinal astrocyte activation after peripheral nerve injury in mice and improves repair after peripheral nerve injury.
