Crystal HRP was applied to the cut ends of the left infraorbital nerve and branches of the facial nerve of 34 adult mice. Then the animals were killed and perfused, and HRP solution was applied to the cut ends of the root of the right facial nerve and the right maxillary nerve. Frozen sections of the brain stem and the trigerminal ganglia were made and reacted with BDHC, TMB or DAB method for light and electrom microscopic examination.Under light microscopy, the neurons labeled when alive in the left trigerminal ganglion and the nucleus of the left facial nerve showed that more cell bodise but less nerve fibers were labeled. The reaction products with all the 3 methods in thess cells were granular. The neurons labeled after death in the right trigerminal ganglion and the nucleus of the right facial nerve showed that more fibers but less cell bodies were labeled. The reaction products in these cells were also granular with BDHC and TMB methods but diffuse with DAB method.Under electron microscopy, there were electron-dense positive products in all the cells labeled either when alive or after death. In those cells labeled when alive, the products were found in the round or oval secondary lysosomes or multive-sicular bodies, while in those labeled after death, they were mostly found on one side of vacuoles without membrane boundary. In the fibers labeled after death, many large or small positive granules were found in the axons and many minute positive granules in the myelin lamellae especially on their inner surface in contact with the axons.

Objective To investigate the value of laparoscopic treatment for post-laparoscopic cholecystectomy complications.Methods From October 1996 to October 2007,totally 754 patients suffering from gallbladder diseases underwent laparoscopic cholecystectomy in our hospital;21 of them developed postoperative complications and received laparoscopic intra-abdominal exploration.Results By laparoscopy,bile leakage was diagnosed in 11 cases,intra-abdominal bleeding in 6,intraperitoneal fluid in 2,duodenal bulb perforation in 1,and obstructive jaundice in 1.The patients who developed obstructive jaundice was converted to open surgery because of hepatic duct transection.The other 20 cases underwent laparoscopic treatment.All the patients were followed up for a mean of 6 years(1 to 11),during which none of them had biliary complications.Conclusion Laparoscopic treatment is a microinvasive,safe and effective method for post-laparoscopic cholecystectomy complications.

Objective To explore the effect of the joint teaching rounds of the multidisciplinary radiotherapy.Methods 54 clinical college students of Grade 2013 was selected as the control group,adopting the traditional single teaching ward round model,while 58 clinical college students of Grade 2014 was selected as the research group,adopting the multidisciplinary joint radiation operation mode.By contrasting the satisfaction questionnaire,calculating and delineating the target volume error rate and the theory examination results,the effect of teaching ward round was evaluated.Results ①According to the survey,the research group's satisfaction in teaching methods,stimulating students' enthusiasm for learning,improving their clinical thinking ability and consolidating the knowledge (respectively 91.38％,86.21％,82.76％,93.10％),was higher than that of the control group (75.93％,68.52％,62.96％,77.78％),and the difference was statistically significant (chi square values were 4.95 5.05,6.25,5.36;P＜0.05).②The research group's pass rate in delineation of Gross Target Volume (GTV) and the Clinical Target Volume (CTV) was (82.76％,86.21％),higher than that of the control group (53.70％,62.96％),and the difference was statistically significant (chi square values were 14.36,9.48;P＜0.01).③Research group's score in clinical Three Basics and oncology theory achievement was(88.75 ± 5.23) and (82.72 ± 3.69),higher than the control group [(81.88 ± 613),(80.74 ± 3.25) points],and the difference was statistically significant (t=6.40 respectively,3.01;P＜ 0.05).Conclusion Radiotherapy department's multi-disciplinary joint ward round helps to improve the teaching quality.

Gallbladder cancer is the most common malignancy of biliary tract, ranking the sixth among gastrointestinal tract cancers worldwide.However, the low resectability, dissatisfied chemosensitivity and multidrug resistance of gallbladder cancer are currently the major challenges in the clinical management.The drug resistance has been reported to be a rather complex process, mainly involving drug effiux pump, drug-resistance mediating enzymes, transcription factors, cell autophagy and so on.Investigating the potential multidrug resistance mechanisms in gallbladder cancer and clarifying the related influential factors is the key to improving the chemosensitivity of gallbladder cancer.Slacking or reversing the resistance and enhancing the chemosensitivity could provide new idea for treating gallbladder cancer.

Objective To explore the clinic value of chromosome karyotype analysis of amniotic fluid cells in prenatal diagnosis . Methods 1 466 cases of pregnant women who had the prenatal diagnosis indexes were selected ,and their amniotic fluid specimens were collected through amniocentesis guiding by type‐B ultrasonic around the 16th to 24th week .Amniotic fluid cells were gained after a successful cell culture .G banding was used for the karyotype analysis of amniotic fluid cells .Results The one‐time success rate of cultivation for amniotic fluid cells was 99 .8% .In 1 466 cases of pregnant women ,there were 16 cases of abnormal karyotype polymorphism (including 12 cases of trisomy 21 ,1 case of trisomy 18 ,and 3 cases of Chromosome abnormalities) and 3 cases of chromosomal polymorphism .Conclusion The chromosome karyotype analysis of amniotic fluid cell is still an irreplaceable test in prenatal diagnosis .
