AIM:To report the safty and efficiency of intravitreal injection of bevacizumab (Avastin) in patients with macular edema (ME) due to branch retinal vein occlusion (BRVO).METHODS: A consecutive series of patients with ME due to BRVO who were treated with intravitreal bevacizumab injection (2.5g/0.1L) were retrospectively studied. Patients underwent complete ophthalmoscopic examination, including Snellen visual acuity testing, optical coherence tomography (OCT) imaging, and/or flurescence angiographic testing at baseline and follow-up visits.RESULTS: There were 32 eyes of 32 consecutive patients who received at least one intravitreal bevacizumab injections (range from 1 to 3). The mean length of follow-up was 4.7 (range from 3 to 8) months. The mean visual acuity improved from 20/200- at baseline to 20/100- at 1 month and 20/100+ at 3 months and last follow-up (P<0.01). The mean central 1mm macular thickness was 483μm at baseline and decreased to 275, 314,and 301μm at 1 month,3 months, and last follow-up (P<0.01)respectively.No adverse side effects were observed following injections in any eyes.CONCLUSION: Intravitreal bevacizumab (Avastin) showed a marked decrease in ME secondary to BRVO, improvement in visual acuity and lack of adverse side effects.

BACKGROUNDStereotactic surgery has been used to treat heroin abstinence in China since 2000 by ablating the amygdaloid nucleus (AMY) and the nucleus accumbens (NAc), which also provides opportunity to identify the relationship between these nuclei and addiction. Our study aimed to explore the physiological and psychological effects of electrically stimulating the AMY and the NAc in heroin addicts after detoxification by observing changes of heart rate, arterial pressure and occurrence of euphoria similar to heroin induced euphoria.
METHODSA total of 70 heroin addicts after detoxification were recruited, and 61 of them were eligible to be given stereotactic surgery for heroin abstinence. The operation was carried out after determining the coordinates of all target nucleuses, and stimulation was performed at the AMY and the NAc solely or jointly. Heart rate, arterial pressure and occurrence of euphoria similar to heroin induced euphoria were recorded and analyzed.
RESULTSThe average heat rate was (66 ± 10) beats/min before electric stimulation, and significantly increased to (84 ± 14) beats/min during stimulation, and changed to (73 ± 12) beats/min 10 minutes after stimulation. There was a significant elevation of the average arterial pressure from 83 mmHg before stimulation to 98 mmHg during the stimulation, and it then decreased to 90 mmHg after stimulation. Forty-three of the 61 patients showed intense euphoria similar to heroin induced euphoria. The largest number (118/186) of euphoric responses occurred when the AMY and the NAc were stimulated at the same time. Odds ratio was 5.4 (95%CI: 2.4 - 11.9, P < 0.0001) to quantify the association. Results from a Logistic regression model showed a positive correlation between unilateral stimulation of either the AMY or NAC and induction of euphoria (OR > 1), especially when the left AMY or left NAc was stimulated (P < 0.05).
CONCLUSIONSOur data are consistent with existing results that the AMY and the NAc are related to addiction. Different roles in drug dependence would be suggested according to the location of the AMY and NAc.

OBJECTIVETo compare the differences in biological behavior and clinical features between adenocarcinoma of the esophagogastric junction (AEG) and lower thoracic esophageal squamous cell cancer (LESC), and to explore reasonable procedures for each cancer.
METHODSClinical data of 111 patients with AEG and 126 patients with LESC who underwent surgery from January 2004 to April 2012 were retrospectively reviewed. Data pertaining to resection rate, lymph node metastasis, and postoperative complication rate were analyzed.
RESULTSThe resection rate was 94.6% for AEG and 97.6% for LESC, and the difference was not statistically significant (P<0.05). The rate of lymph node metastasis in the mediastinum in patients with AEG was significantly lower [6.3%(7/111) vs. 32.5%(41/126), P<0.01], while the rate of lymph node metastasis in the abdomen was significantly higher [57.7%(64/111) vs. 34.1%(43/126), P<0.01]. The rate of lymph node metastasis in mediastinum of AEG was 12.5%(4/32) for Siewert I and 4.7%(3/64) for Siewert II, and there was no lymph node metastasis in Siewert III (n=15). For AEG patients who underwent trans-abdominal surgery, the rate of positive lymph node in the middle and lower mediastinum was significantly lower than trans-thoracic surgery [0/22 vs. 7.9% (7/89), P<0.05]. LESC via right thorax with two-field or three-field lymph node dissection was associated with a significantly higher rate of positive lymph node metastasis in the upper mediastinum than that of single incision via left thorax [17.9%(12/67) vs. 0/59, P<0.01]. The postoperative complication rates were 23.4%(26/111) and 27.0%(34/126) respectively, and the difference was not statistically significant(P>0.05).
CONCLUSIONSAEG and LESC show different lymph node metastasis pattern and should be operated differently. Lymphadenectomy in mid-lower mediastinum should be emphasized in Siewert I and Siewert II type cancers.

OBJECTIVETo compared the efficacy of drug-coated balloon and common balloon for treatment of superficial femoral artery and popliteal artery occlusive disease.
METHODSForty-six patients were admitted for ipsilateral single or multiple superficial femoral artery and/or popliteal artery lesions (between 3 and 15 cm stenosis or occlusion), Rutherford grades 2 to 5, with or without other accompanying diseases in the Department of Interventional Vascular Therapy of the First Hospital of Nanjing between September, 2015 and December, 2016. The patients were randomly assigned into drug-coated balloon (DCB) group (n=23) and common balloon (CB) group (n=23). None of the patients had stent restenosis, aneurysms, acute thrombosis, pregnancy, life expectancy less than 1 year, or below-the-knee artery occlusion. The late lumen loss (LLL), improvement of the ankle brachial index (ABI), improvement of Rutherford grade, incidence of restenosis, thrombosis rate and amputation rate were compared between the two groups at 6 months after treatment.
RESULTSThe two groups of patients were comparable for general conditions, risk factors, and characteristics of the compromised vessels (P>0.05). Six months after treatment, the patients in DCB group showed significantly smaller LLL, more obvious improvement of the ABI and Rutherford grade, and lower restenosis rate and thrombosis rate than those in CB group (P<0.05). The amputation rates were similar between the two groups (P>0.05).
CONCLUSIONSDCB shows obvious advantages over common balloon for treatment of superficial artery and popliteal artery arteriosclerosis obliterans in that it more effectively reduces LLL, restenosis rate and thrombosis rate and improves the ABI and Rutherford grade at 6 months after the treatment.

We found previously that ACh can significantly inhibit the proliferation of cultured human pituitary adenoma cells. In order to make a further investigation of the mechanism of the inhibitory effect of ACh on the proliferation of pituitary adenoma cells, we observed the levels of protein kinase C (PKC), [Ca(2+)](i) and cAMP/cGMP in cultured pituitary adenoma cells after treatment with ACh. The results demonstrate that (1) compared with control, PMA, a PKC activator, increased the activity of cytoplasm, membrane and total PKC in human pituitary adenoma cells. However, after a 15-min treatment with ACh (10 micromol/L), a significant reduction of the activity of cytoplasm, membrane and total PKC in human pituitary adenoma cells was observed, and the reduction effect could be blocked by atropine. (2) The level of [Ca(2+)](i) of single adenoma cells was found to decrease immediately on the addition of ACh (10 micromol/L), which could also be blocked by atropine. (3) ACh increased the amount of cAMP in the cytoplasm of human pituitary adenoma cells, but had no effect on that of cGMP. These data provide an important clue to explore the molecular mechanisms of the inhibitory effect of ACh on the proliferation of pituitary adenoma cells, and suggest that the modulating effect of ACh on the proliferation of pituitary adenoma cells results from the interactions of several cellular signaling pathways.
