Objective:To study the effect of Ginkgo biloba extract (EGb761) on metabolism of aflatoxin B_1(AFB_1) in Wistar rats. Methods:Seventy one Wistar rats were divided into three groups at random: group A (AFB_1 group), group B (AFB_1+EGb761 group), and group C (control group). The rats in groups A and B were given AFB_1(intraperitoneal injection, 100-200 μg/ kg body weight, 1-3 times/week). The rats in group B were fed the food containing EGb761 while the rats in groups A and C were given normal food. Blood samples were collected and liver biopsy was performed on the 14th, 28th and 42nd week. All the rats were sacrificed at the 64th week. The incidence of hepatoma was observed. The hepatic phase Ⅰ drug-metabolizing enzyme CYP450 and phase Ⅱ enzyme GST were detected by spectrometry. The serum AFB_1-lysine adduct was determined by high performance liquid chromatography (HPLC). The expression of 8-hydroxydeoxyguanosine(8-OHdG) was measured by immunohistochemistry. Results:The incidence of hepatocellular carcinoma (HCC) in group B was significantly lower than that in group A (26.92% vs 76.00%,P<0.001). No hepatocellular carcinoma developed in group C. EGb761 had no effects on the activities of CYP450 and GST in rat liver tissues. The level of AFB_1-lysine adduct reached the peak (4 356.01 pg/mg albumin) at the 14th week in group A. EGb761 significantly inhibited the formation of AFB_1-lysine adducts in serum by 13.07% at the 14th week (P=0.033), and 73.63% at the 42nd week (P=0.002). The expression of 8-OHdG protein in rat liver tissues in group B was significantly lower than that in group A at the 28th, 42nd, and 64th week (P<0.05). Conclusion:The main mechanism underlying the effect of EGb761 in blocking hepatogenesis induced by AFB_1 may not be fully related with its influence on the activity of liver phase Ⅰ and phase Ⅱ metabolizing enzymes. EGb761 inhibites the production of AFB_1-lysine addcuts, decreases the expression of 8-OHdG protein, and finally alleviates the DNA oxidative injury, which may be one of the mechanisms for the effects of EGb761 in inhibiting or delaying hepatogenesis induced by AFB_1.

To evaluate the visual performance of the patients with traumatic corneal astigmatism, after the treatment of topography guided off-flap epipolis laser in situ keratomileusi (off-flap Epi-LASlK).
●METHODS: This prospective clinical study was comprised of 21 eyes of 21 patients with irregular corneal astigmatism caused by trauma, they were treated by off-flap Epi - LASlK from July 2012 to December 2013. The data included uncorrected visual acuity ( UCVA), best spectacle - corrected visual acuity ( BSCVA ), contrast sensitivity 1, 6mo before and after surgery; the healing area percentage of corneal epithelia, the healing time of corneal epithelia and pain score at 3d after surgery.
●RESULTS: Postoperative 1mo both UCVA and BSCVA were improved significantly than that before surgery (t =15. 703, 4. 351, P< 0. 05); Compared with the 1mo after surgery, UCVA at 6mo after surgery raised significantly (t= 6. 867, P <0. 05). There was no statistical significance between 6 and 1mo after surgery about BSCVA (t= 1. 497, P = 0. 140 ). After surgery, mean spherical equivalent (SE) was reduced from -2. 43±3. 02D to -0. 23±0. 49D (P<0. 05), and the mean cylinder was reduced from -1. 86± 2. 23D to - 0. 46 ± 1. 03D (P< 0. 05). Postoperative 1mo,4 kinds of spatial frequency and contrast sensitivity had no significant difference compared with the preoperative (P>0. 05 ). Postoperative 6mo except the 3c/ d spatial frequency, the remaining 3 spatial frequency contrast sensitivity compared with those before operation were significantly improved ( P < 0. 05 ). The healing area percentage of corneal epithelia was 92. 46% ±8. 24% (80% -100%) at 3d after surgery; The healing time of corneal epithelia was 3. 50 ± 1. 56d; Pain scores at 3 and 7d after surgery was 1. 54±1. 32 and 0. 04±0. 64, respectively.
●CONCLUSlON: Topography-guided off-flap Epi-LASlK is safe and effective in treating the patients with traumatic corneal irregular astigmatism. The operation can improve both the contrast sensitivity and the visual performance.

OBJECTIVETo observe amplitude changes of low frequency fluctuation in brain spontaneous nervous activities induced by needling at Hand Taiyin Lung Channel, and to preliminarily explore the possible brain function network of Hand Taiyin Lung Channel.
METHODSBy using functional magnetic resonance imaging (fMRI), 16 healthy volunteers underwent resting-state scanning (R1) and scanning with retained acupuncture at Hand Taiyin Lung Channel (acupuncture, AP). Data of fMRI collected were statistically calculated using amplitude of low frequency fluctuations (ALFF).
RESULTSUnder R1 significantly enhanced ALFF occurred in right precuneus, left inferior parietal lobule, bilateral superior temporal gyrus, bilateral middle frontal gyrus, left superior frontal gyrus, left inferior frontal gyrus, left medial frontal gyrus. Under AP significantly enhanced ALFF occurred in right precuneus, bilateral superior frontal gyrus, cerebellum, bilateral middle frontal gyrus, right medial frontal gyrus, and so on. Compared with R1, needing at Hand Taiyin Lung Channel could significantly enhance ALFF in right gyrus subcallosum and right inferior frontal gyrus. Significant decreased ALFF appeared in right postcentral gyrus, left precuneus, left superior temporal gyrus, left middle temporal gyrus, and so on.
CONCLUSIONNeeding at Hand Taiyin Lung Channel could significantly change fixed activities of cerebral cortex, especially in right subcallosal gyrus, right inferior frontal gyrus, and so on.

An effective, reliable and practical staging is of great help to the diagnosis and treatment of malignant tumors. Cervical cancer is a malignant tumor using clinical stage in gynecological tumors, but staging lacks objectivity in judging the tumor size, para-uterine invasion, vaginal margin, vascular invasion and so on. By October 2018, the International Federation of Obstetrics and Gynecology (FIGO) had revised the 2009 FIGO cervical cancer staging that had been used before.However, the changed points of the 2018 FIGO cervical cancer staging are controversial.

OBJECTIVETo investigate the characteristics of erectile dysfunction (ED) in old males with lacunar infarction.
METHODSA total of 38 old patients ages from 60 to 70 years were involved. The questionnaire of international index of erectile function 5 (IIEF -5) was used to determine the status and severity of ED. According to the focus of infarction on MRI, the patients were divided into two groups, Group I with lacunar infarction and minor neurological deficits, and Group II with none. The total IIEF-5 scores were compared between the two groups and repeatedly evaluated six months after discharge.
RESULTSAccording to the total scores of IIEF-5, the prevalence of ED in Group II (95%) was higher, and the incidence of severe ED was significantly increased (60.0% vs. 44.4%, P < 0.05) as compared with Group II. In both the two groups, severe ED was more often seen in diabetic patients. At six months after discharge, the total scores of IIEF-5 were significantly increased (11.2 +/- 3.2 vs. 15.6 +/- 2.2, P < 0.05).
CONCLUSIONED is significantly increased in old males with lacunar infarction, and it is more severe in diabetic patients. Post-stroke rehabilitation care helps to improve ED.

In order to evaluate the incidence of chromosomal abnormalities in patients with polycythemia vera (PV) accurately and to investigate the value of fluorescence in situ hybridization (FISH) technique in the detection of trisomies 8 and 9, conventional cytogenetics (CC) technique was used to detect karyotype and interphase FISH was used to detect trisomies 8 and 9 in 50 newly diagnosed PV and 8 normal individuals. The results showed that out of 50 cases, the 3 cases had chromosome karyotype abnormality, including trisomy 8, deletion of chromosome Y and inversion of chromosome 11 by CC technique. FISH method detected two cases of trisomy 8, including one case confirmed by CC technique, and one case of trisomy 9 neglected by CC technique. It is concluded that the incidence of chromosomal abnormalities in patients with PV is rare, and the incidence of trisomy 8 and trisomy 9 found in this study are relatively lower than that have been reported which may be related to the limited number of samples. Interphase FISH, as an important complement to CC, is a useful method for the detection of trisomies 8 and 9.
