Background Conventional chemical method to fix the entire eyeball results in the edema of retinal nerve fiber layer and therefore influent the evaluation of tissue structure.Research showed that microwave irradiation can avoid this phenomenon. Objective This study was to investigate the appropriate energy and time duration of microwave irradiation for fixation of rabbit eyes specimen and compare the influence of different fixation methods on retinal structure. Methods Twenty-two New Zealand white rabbits were sacrificed by using venous air embolism.The eyeballs were enucleated from the rabbits and immersed in chemical reagents with glacial acetic acid,methyl aldehyde and chloroform for 2 days as the control group.The eyeballs were immersed in 400 ml physiological balance solution immediately,and then were fixed by microwave irradiation for 80,160,240 and 320 seconds under the lower power as the microwave irradiation groups.In the microwave irradiation+chemical fixation group,the specimens were immersed in chemical reagents for 1-2 hours after the microwave radiation.The morphology of retinal structure was examined and area of retinal detachment was calculated by hemotoxylin and eosin staining under the light microscope. Results A better fixation effect was obtained in the retinal section of microwave radiation for 240 seconds in comparison with that of the traditional chemical reagent fixation method for 2 days.The retina detachment ratio was 16.3%±11.5% for simple microwave method,50.0%±24.5% for chemical method,and 6.7%±7.8% for microwave+chemical method.showing a significant difference among 3 groups(F=32.43,P=0.000).Retinal staining was clear and retinal structure was almost normal in the specimens of microwave+chemical fixation group with 200-240 seeonds microwave irradiation and 1-2 hours chemical fixation. Conclusion Microwave irradiation method is a more ideal way for the fixation of retina because of taking short duration,lower toxicity and better staining.The combination of microwave radiation and chemical reagents can acquire an excellent quality of retinal section.

Objective To investigate the feasibility, indications, operating technique and the clinical value of laparoscopeic surgery for ectopic pregnancy with prior history of obstetric and gynecologic operations. Methods 82 ectopic pregnancy patients with prior history of the obstetric and gynecologic operation were subjected to laparoscopic surgery. Among them, 60 patients had undergone prior obstetric and gynecologic operation only once, 21 patients had undergone twice, and the remaining one had undergone obstetric and gynecologic operation three times. The laparoscopic operation was completed in different ways as follows: puncture and injection of drug under laparoscopy, salpingectomy, resection of pregnancy in oviduct, removal of embryo through incision of oviduct under laparoscope, suction removal of embryo from oviduct, and new technique for pregnant surgery at interstitial portion. Results Of these 82 patients undergoing laparoscopic surgery, 73 cases had adhesion in different degree, and the adhesion rate was 89.0% (73/82). In the 60 patients with history of one operation, pelvic peritoneal adhesion was found in 51 patients, the adhesion rate was 85.0%. All 22 patients with two prior operations had pelvic peritoneal adhesion, and the rate was 100.0%. The laparoscopic surgery was successful in 70 cases. The rate of success was 85.4%, while in 12 patients, the operation was changed into laparectomy due to dense adhesion, and the rate was 14.6%. Of these 12 patients, in 5 of them there was endometriosis, in 6 patients chronic pelvic inflammation was found, 9 patients had a surgical history for ectopic pregnancy, 2 patients with the history of caesarean section, and one patient had a history of complicated gynecologic operation. Complications included colonic injury in one patient with ectopic pregnancy, and the operation was changed to laparotomy. Injury to the ureter happened in one patient. The operation time for laparoscopic surgery was 30-180 min. Conclusions The laparoscopic operation is an effective procedure and it has become a routine procedure for ectopic pregnancy with prior history of obstetric and gynecologic operation. Because of chronic pelvic inflammation and endometriosis, it is difficult to perform laparoscopic surgery successfully, and laparotomy should be anticipated at all time.

Nicotinamide phosphoribosyltransferase (NAMPT) is the rate-limiting enzyme in the salvage pathway for the biosynthesis of nicotinamide adenine dinucleotide (NAD+) from nicotinamide. NAMPT is also a cytokine that inhibits the apoptosis of neutrophils under various inlfammatory stimuli, regulates various diseases and closely associates with the progression and prognosis of cancers. However, it is still not clear whether the cytokine-like function of NAMPT is interrelated with the biosynthesis enzyme activity of NAD+. This article aims to provide novel insights for inflammation and cancers treatment by reviewing the function of NAMPT in inflammation, carcinogenesis, cancer progression and its inhibitors, APO866/FK866.
