AIM: To analyze the application on frequency domain optical coherence tomography ( OCT ) technology of pathologic myopia optic disc neurosensory retinal thickness changes and its relationship with axis oculi, sex and age, and help for the early diagnosis of pathological myopia and primary open angle glaucoma.
METHODS:Collected 96 eyes of normal eyes ( axis oculi 23-24mm) and 153 eyes of pathologic myopia eyes ( axis oculi 25-27mm 80 eyes, >27mm 73 eyes). We measured the thickness of nerve fiber layer of the optic disc by OCT and analyzed their relationship with axis oculi, sex and age with multiple linear regression analysis.
RESULTS: The observation group showed significant smaller average thickness of peripapillary, superior, inferior, nasal than the control group ( P<0. 05 ); the difference in the temporal quadrant between the groups were no statistically significant differences (P>0. 05); The partial correlation coefficient of peripapillary average thickness of nerve fiber layer and axis oculi was -1. 31, gender was 5. 21, age was -0. 12.
CONCLUSION:The thickness of nerve fiber layer of the optic disc in the pathologic myopia eyes are decreased than normal eyes, axis oculi, sex and age are influenced factors. The pathologic myopia patients should use different index combined with optic nerve fiber layer thickness decreased to help for the diagnosis of early primary open angle glaucoma.

AimTo evaluate the efficiency of gene amplification technique used in detecting the specimens colleted from rodents to identify natural epidemic foci of scrub typlus. MethodMice of Kunining strain were experimentally infected by a certain amount of Oriential tsutsugamushi. The specimens of blood clot and spleen from the infected animals were detected by nested polymerase chain reaction(nPCR)specific to O. T sutsugamush at the day 3,6 and 9 of post-infection. Then the technique was used for detection of samples collected from field. As an infected index ,the specimen was considered to be positive only if a 88-bp DNA fragment from Sta 58kDa gene of O. Tsutsugamushi could be produced. According to the study ,it was estimated whether or not that the sampling area is a natural epidemic focus of the disease. ResultsThe specimens of both blood clot and spleen from the mica at day 3 of post-infecction showed negative to the specific PCR product ,but positive when detected at day 6 and hereafter. Of 111 spleen samples from the field collections in the northwest of Fujian province,one was positive, and another positive sample was in the 29 blood clots from Jiangxi province. It is demonstrated that these areas have been the natural epidemic foci. Conclusion The nPCR method is of highly sensitive and specific to be used in the etiologic study on specimens from field rats.

Objective:To evaluate the prediction value of preoperative Fibrinogen(FIB) in combination with neutrophil-lymphocyte ratio(NLR)for the prognosis of operable pancreatic cancer patients.Methods:The clinical data of 124 patients who underwent radical resection for pancreatic cancer in our hospital from Jan 2010 to Dec 2018 were retrospectively analyzed.The patients were divided into three groups according the high and low NLR, FIB value which defined by the receiver operating characteristic curve (ROC). The clinicopathological data and overall median survival time were compared between the three groups.Results:Univarate analysis showed that age, tumor stage, NLR, FIB and F-NLR score were associated with the prognosis( P<0.05), while multivariate analysis showed that high F-NLR score was the independent prognostic factor. The median survival time of patients with F-NLR scores 0, 1 and 2 group was 30.6, 20.3 and 13.9 months( P<0.05). The prognosis of high F-NLR score was significantly worse than that of low F-NLR score( P<0.05). Conclusions:A high preoperative F-NLR score was a promising predictor for the prognosis of pancreatic cancer patients after radical resection.
