AIM: To investigate the clinical effects of intravitreal Bevacizumab for 26 cases with retinopathy of prematurity (ROP) in Zone Ⅰ.
METHODS:A retrospective study. Totally 26 ROP infants between September 2013 and October 2014 diagnosed as high - risk ROP in Zone Ⅰ had been treated with intravitreal bevacizumab. They were divided into three groups, pre - threshold ROP, threshold ROP and acute posterior ROP ( APROP ). Postoperative effects were compared.
RESULTS:There were 26 infants (52 eyes) diagnosed as ROP in Zone Ⅰ, including 3 infants( 6 eyes) with pre -threshold ROP, 15 infants (30 eyes) with threshold ROP and 8 infants (16 eyes) with APROP. The first operation recovery rate of three groups respectively were 100% (6 /6), 60% ( 18 / 30 ) and 75% ( 12 / 16 ), which were not significantly different (P>0. 05).
CONCLUSION:Intravitreal bevacizumab for ROP in ZoneⅠ seems effective and has some advantages over conventional laser treatment, which could be first line treatment for high-risk ROP in Zone Ⅰ.

Objective:To discuss the oncologic safety, aesthetic outcome, and upper extremity function of single-port insufflation endoscopic nipple-sparing mastectomy (SIE-NSM) in the treatment of early breast cancer.Methods:From January 2014 to August 2019, a total of 80 patients with stage Ⅰ and Ⅱ breast cancer underwent SIE-NSM, at Beijing Friendship Hospital, Capital Medical University were retrospectively analyzed and followed up. Estimated the oncologic safety, aesthetic outcome, and upper extremity function.Results:SIE-NSM was performed successfully on all 80 patients.There was no serious complication after surgery.The follow-up time was 16-82 months and the median follow-up time was 42 months. Local recurrence occurred in two patients, and there was no distant metastases. Four (5%) patients developed grade 1-3 nipple-areola complex ischemia. There were no cases of subcutaneous effusion.The satisfaction with breasts, chest well-being, psychosocial well-being, and sexual well-being scores were confirmed to be highly rated by Breast-Q scale. Upper extremity function score confirmed that good upper limb function was preserved after surgery. The mean length of incision was (3.6±0.8) cm, and the blood loss was (24.7±19.3) mL.Conclusions:SIE-NSM can achieve a higher cosmetic score and a better recovery of upper limb function on the premise of ensuring the safety of the tumor.This novel method is an appropriate surgical option for patients with early breast cancer.

OBJECTIVETo investigate the association of fasting and postpiandial triglyceride with carotid intima-media thickness among type 2 diabetic patients in southeast China.
METHODSA total of 78 type 2 diabetic patients from southeast China were recruited. All the subjects underwent a standardized mixed-meal test (SMMT) and an oral glucose tolerance test. Carotid intima-media thickness (IMT) was measured by color doppler ultrasound examination.
RESULTSPostprandial triglyceride (PTG) after SMMT increased significantly in type 2 diabetic patients. The carotid IMT in patients with postprandial hypertriglyceridemia was significantly greater than that in patients with postprandial normal-triglyceridemia (0.90 mm vs 0.81 mm, P < 0.05), which remained significant after adjustment for fasting TG and HDL-c levels, and the IMT in patients with fasting hypertriglyceridemia only had tendency to increase compared to patients with fasting normal-triglyceridemia (0.87 mm vs 0.84 mm, P > 0.05).
CONCLUSIONThe results suggest that postprandial hypertriglyceridemia may be an independent risk factor of early atherosclerosis in type 2 diabetes.

OBJECTIVETo evaluate the clinical outcome of accessory navicular fusion for treatment of the painful accessory navicular bone of type II in adults.
METHODSFrom June 2006 to June 2012, a total of 38 feet (in 35 adult patients) with painful accessory navicular with type I underwent an fusion operation of the primary and accessory navicular bones,including 26 males and 9 females with a mean age of (32.4±7.3) years old ranging from 18 to 44 years old. The course of disease ranged from 3 to 10 months. The perioperative complications and radiological outcomes were observed and recorded. The foot function before and after operation were assessed by the American Orthopedic Foot and Ankle Society (AOFAS) midfoot score, and the easement of the pain was evaluated by visual analog score (VAS).
RESULTSTwo patients had transient superficial inflammation of the incision, no obvious perioperative complications occurred. All patients were follow-up for (53.5±14.7) months (12 to 84 months). Bone union was confirmed on plain radiography in 32 cases (35 feet). The mean time from the operation to union was (13.7±2.3) weeks (9 to 18 weeks). Postoperative pain VAS score was improved obviosly than preoperative (V=12.14,P< 0.01). The talar-to-first metatarsal angle [(9.4±3.5)° vs (8.3±2.7)°, t=0.736, P>0.05)], calcaneal tilt angle [(17.7±2.2)° vs (18.9±3.4)°, t=0.794, P>0.05],talonavicular uncoverage angle [(14.3±3.4)° vs(12.5?4.6)°,t=0.947, P>0.05) ],and height of the first tarsometatarsal joint [(14.8±3.1) mm vs (15.9±2.8) mm,t=0.814,P>0.05)] before and after operations had no statistic difference. The AOFAS midfoot score was improced from preoperative 45.6±5.3 to postoperative 82.5±7.4 (t=3.214,P< 0.01).
CONCLUSIONFor the painful accessory navicular bone of type II in adults, if the patient has a large navicular bone and not complicated with rigid flatfoot, once the conservative treatment fails, fusion of the primary and accessory naviculars may be a successful intervention. Overall, the procedure provides reliable pain relief, definite foot function improvement, and good patient satisfaction.

OBJECTIVE To explore the expression of long non-coding RNA (LncRNA) HOTAIR, enhancer of Zeste homolog 2 (EZH2) and vascular endothelial growth factor (VEGF) in nasopharyngeal carcinoma (NPC) and their relationship between HOTAIR and prognosis. METHODS We examined the expression of HOTAIR, EZH2 and VEGF in NPC tissues, and analyzed the clinical significance of HOTAIR expression in patients with NPC. RESULTS We found that the expression of HOTAIR, EZH2 and VEGF in the NPC tissues were significantly higher than those in the chronic nasopharyngitis tissues in the gene and protein levels (U=955,P<0.05). The HOTAIR was positively correlated with VEGF (r=0.599,P<0.001), VEGF was positively correlated with EZH2 (r=0.369, P=0.012), and HOTAIR had no significant correlation with EZH2 (r=0.139,P=0.357). Moreover, HOTAIR expression levels increased with clinical stage progression. CONCLUSION The expression of HOTAIR, EZH2 and VEGF were significantly increased in the NPC tissues, and the expression of HOTAIR was related with the TNM stage, the clinical stage and the short term therapeutic effect of the NPC patients, which indicated that the HOTAIR might be used as a biological indicator to determine the prognosis of the NPC.
