We report a case of an 18-year-old woman with systemic antibiotic anaphylaxis who presented anasarca and bilateral visual loss two weeks after the intravenous use of pazufloxacin. Ancillary fundus tests revealed bilateral cotton-wool spots, Purtscher flecken, edema, and retinal arteriolar occlusion around the optic disc. After pulse corticosteroid, administration of anti-anaphylactic agent, and general support therapy for one month, the patient showed a favorable change, with the symptoms lessened or free systemically, except the continuous aggravation of fundus ischemic change. After two intravitreal injections of Ranibizumab, there were still a large area of capillary non-perfusion and neovacularizations in the binocular retina, resulting in vitreous hemorrhage. The patient's visual acuity had still light perception after right-eye vitrectomy and presented no improvement during the postoperative follow-up of two years. Literature review revealed that there were many causes associated with Purtscher-like retinopathy, and the consequent visual impairment varied significantly. Prompt management of the underlying condition is crucial in giving the patient the best chance to restore vision.

INTRODUCTIONMinimally invasive surgical ablation is an emerging alternative method to catheter ablation and the full surgical maze procedure for nonpharmacologic treatment of atrial fibrillation (AF). We present a totally thoracoscopic "box lesion" radiofrequency ablation procedure in patients with paroxysmal or persistent AF.

MATERIALS AND METHODSFrom June 2011 to October 2012, 14 patients with lone paroxysmal (n = 7) or persistent AF (n = 7) were enrolled in this study. Procedures were performed through 3 5-12 mm holes on each side of the chest wall. A bipolar ablation device was used to create a box lesion in the posterior wall of the left atrium that encircled the 4 pulmonary veins (achieving bilateral pulmonary vein/posterior left atrial wall isolation). Perioperative complications were recorded for all patients. Freedom from AF was assessed by 24-hour Holter monitoring every 3 months or during symptoms of arrhythmia.

RESULTSThe ablation was successfully performed in all patients, with median operation time of 128 minutes (range, 45 to 180 minutes). No operative mortality or morbidity were noted during the study period. Freedom from AF was achieved in 12 patients (85.7%) during follow-up (median follow-up 9 months). One patient with persistent AF was shifted to paroxysmal AF. No atrial flutter or atrial tachycardia was noted during the follow-up.

CONCLUSIONThese early results show that totally thoracoscopic surgical ablation using a unique "box lesion" procedure for persistent or paroxysmal AF is a feasible and effective method with good short-term results. Further study is necessary to validate this result.

AIMTo prepare verapamil hydrochloride controlled-onset extended-release pellets (VH-COERP) and study its release behavior in vitro. To compare the pharmacokinetic characteristics and bioavailability in six Beagle dogs after oral administration of VH-COERP and verapamil hydrochloride delayed-release pellets (VH-DRP) as reference.

METHODSThe core of VH-COERP were prepared in the fluidized bed (mini-glatt) by spraying water solution containing drugs onto sucrose-starch pellets with hydroroxy propyl methyl cellulose (HPMC) as the inner coating swelling layer and ethylcellulouse aqueous dispersion as the outer coating controlled layer. Through modifying the coating level of inner and outer layer, the VH-COERP with the optimized cumulative release profile was obtained. The concentration of VH in plasma of six dogs and its pharmacokinetic behaviors after oral administration of VH-COERP and VH-DRP at different times were studied by RP-HPLC. The pharmacokinetic parameters were computed by software program 3P97.

RESULTSThe lag time, the release behavior and the amount of VH from VH-COERP within 24 hours were not influenced by the pH of dissolution medium and post-process, but obviously influenced by the different kinds of added material in swelling layer and the coating level of the inner swelling layer and the outer controlled layer. In vitro the lag time of release profile of VH from VH-COERP was 5 h and then VH was extended release from VH-COERP in the following time. Compared with the VH-DRP, VH-COERP in vivo has an obviously lag time (4 h) , Tmax was also delayed (8 h) and the relative bioavailability was (94.56 +/- 7.64)%.

CONCLUSIONThe release profile of VH from VH-COERP was shown to be extended-release after an conspicuous lag time in vitro and in vivo. So the drug can be taken by the patient before bed time and begin to work at the morning.

OBJECTIVETo explore the diagnostic and therapeutic methods for perioperative children with congenital heart disease (CHD) with airway stenosis in pediatric intensive care unit (PICU).

METHODFiberoptic bronchoscopy was used for the diagnosis of 100 CHD cases in PICU who were clinically considered to have possible airway malformation because of complicated difficult-to-control lung infection, atelectasis and failure with the ventilator after surgery from January 2010 to October 2011. Cases who were confirmed to have severe airway stenosis by bronchoscopy and weaning from the ventilator after surgery were treated with balloon expandable stents into the desired position in the bronchoscopy.

RESULTThere were 73 cases (73%) of CHD patients with airway abnormalities, including 31 cases of severe stenosis (31%), moderate stenosis in 29 cases (29%), mild stenosis in 13 cases (13%). Nine of the 10 children in whom the mechanical ventilation was hard to be stopped after surgery because of severe airway stenosis were weaned from mechanical ventilation successfully by fiberoptic bronchoscopy, while one case died from primary disease with severe sepsis after the placement of bronchial stents.

CONCLUSIONCHD children with difficult-to-control lung infection, atelectasis and failure with ventilator after surgery are often complicated with airway abnormalities. The therapeutic bronchoscopy with airway stent can be used for cases with weaning from the ventilator because of severe airway stenosis.

OBJECTIVE: To explore the molecular mechanisms of colonic epithelial aging related proteins and aged colonic epithelial susceptibility to tumor. METHODS: The proteins of normal human colonic epithelial tissue from young and old people were separated by 2-dimensional gel electrophoresis (2DGE), respectively. Then gels were stained by silver, scanned by imagescanner and analyzed with PDQuest software. The differentially expressed protein spots of colonic epithelium between the old and the young groups were identified by peptide mass fingerprint based on matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF-MS) and database searching. RESULTS: Well-resolved and reproducible 2DGE maps of normal human colonic epithelium from the young and the old were acquired. Nineteen more than 2 fold differentially expressed protein spots were identified representing 17 different proteins by MALDI-TOF-MS. The functions of these proteins involve in metabolism, energy generation, transportation, antioxidation, translation and protein folding. CONCLUSION Seventeen aging related proteins of human colonic epithelium identified indicate that injury of mitochondrial function and decline of antioxidant capability are important reasons for the aging of human colonic epithelium. These data provided useful clues for elucidating the mechanisms of colonic epithelial aging and aged colonic epithelial susceptibility to cancer.

OBJECTIVETo observe and compare the analgesic effect of electroacupuncture (EA) at "Sanyinjiso" (SP 6), "Hegu" (LI 4) and "Xuehai" (SP 10) in dysmenorrhea rats so as to investigate the functional specificity of acupoint.

METHODSOne hundred SD female rats aged three-month-old in the diestrus examined by the vaginal smear screening were randomly divided into a saline group, a model group, a Sanyinjiao (SF 6) group, a Hegu (LI 4) group and a Xuehai (SF 10) group, 20 rats in each group. The rats in the last four groups were given Estradiol Benzoate combined with Oxytocin to prepare the models of dysmenorrhea and in the saline group were given the same dose of saline. Last three groups were treated with electroacupuncture (EA) at Sanyinjiao" (SF 6), "Hegu" (LI 4) and 'Xuehai" (SF 10) respectively. The writhing behaviors of the rats in each group were observed within 20 min performing electroacupuncture from the start of the pain and the waveforms of uterine contraction were recorded.

RESULTSIn terms of the writhing behaviors, the writhing latency in the Hegu (LI 4) group was extended significantly (P < 0.05, P < 0.01) and the writhing numbers in the Hegu (LI 4) group were decreased significantly (both P < 0.05) as compared with those in the Sanyinjiao (SF 6) group and in the Xuehai (SF 10) group. In terms of the waveforms of uterine contraction, compared with that in the model group, the amplitude and the activity of uterine contraction in both Sanyinjiao (SF 6) group and Hegu (LI 4) group were decreased significantly (all P < 0.05), and with no significant difference between the Xuehai (SF 10) and the model group (P > 0.05).

CONCLUSIONFor comprehensive assessment of the analgesic effect of electroacupuncture at different acupoints by using the writhing behaviors and the waveforms of uterine contraction, "Hegu" (LI 4) is the best, "Sanyinjiao" (SP 6) is the next and "Xuehai" (SP 10) is the third. showing a relatively functional specificity of the acupoint.

OBJECTIVETo observe the long-term effect of plasma-derived HBV vaccine.

METHODSThe effect of a plasma-derived HBV vaccine which was given to children born in 1986 in Huangpu district in Shanghai were followed up once every two years and testing for HBsAg, anti-HBs and anti-HBc was carried out. Compared to background results from cross-sectional survey of hepatitis B virus in 1984 and 1985 (as internal control) as well as finding of survey targeted in non-plasma-derived HBV vaccine of children born in the same time in the nearby area from results investigated in 1991 (as external control), positive rate was calculated to assess the effect of protection.

RESULTSThe population immunized was followed up for 23 years and 5993 blood samples were collected. During the period of follow-up, the positive rate of anti-HBs decreased from 89.01% to 18.77% and the average level was 40.39%. The average positive rate of anti-HBc was 1.87%. The annual positive rate fluctuated around the average level. HBsAg positive rate remained less than 1.00% (0.46% - 0.98%), with an average of 0.62% (37/5993). Ranges of positive efficacy were from 81.37% to 95.78% against background control and 72.76% against external control.

CONCLUSIONThe plasma-derived HBV vaccine showed a good long-term protective effect and there was no need for boosting the immunization 23 years later.
