Objective To evaluate the feasibility and efficacy of subfascial endoscopic perforator surgery in treating varicose ulcer after great saphenous vein stripping.Methods Between July 2008 and July 2013,152 limbs of venous ulceration after great saphenous vein stripping were divided into two groups (conservative therapy and subfascial endoscopic perforator surgery therapy) and followed up at least for 2 years,respectively compared symptoms and signs improvement,ulcer healing time,ulcer healing and ulcer recurrence rate after healing for 6,12,24 months.Results No patient underwent the surgery occured pulmonary embolism or death,2 limbs appeared hematoma.Conservative and subfascial endoscopic perforator surgery group's symptoms and signs improvement rates were 81.9％ (59/72) and 86.3％ (69/80) (not significant,P =0.528),while the ulcer healing time,ulcer healing and ulcer recurrence rate respectively were 65.3％ (47/72) and 78.8％ (63/80),(73 ±15.7) d and (41 ± 12.6) d,34.0％ (16/47) and 14.3 ％ (9/63) (significantly different,P ＜ 0.05).According to the three time-points' (6,12,24 months) follow-up,the non-recurrence rate were 89.4％ (42/47) and 96.8％ (61/63),P=0.135;72.3％ (34/47) and 92.1％ (58/63),P=0.006;66.0％ (31/47) and 85.7％ (54/63),P =0.014.Conclusions Subfascial endoscopic perforator surgery is a reliable,safe and minimally invasive surgery,and has a long-term effect in treating varicose ulcer after great saphenous vein stripping.

Objective To summarize perioperative care and effect of surgical treatment of total anomalous pulmonary venous connection (TAPVC) in newborns and babies within 6 months.Methods From September 2001 to May 2013,ninetytwo consecutive patients with TAPVC received surgical correction under cardiopulmonary bypass (CPB) with moderate or deep hypothermia.The anatomic subtype included supracardiac type 48,intracardiac type 36,infracardiac type 6 and mixed type 2.There were 36 newboms.Pathological diagnosis was made by echocardiogram,computerized tomography and operative findings during operation.The option of procedure was determined by findings.Respirator assisted breathing after operation and cardiac function was maintained by a variety of positive inotropic drugs,to prevent the happening of the pulmonary hypertension crisis.Results Severely low cardiac output syndrome occurred in 8 patients and they died within 24 hours after operation.The remaining cases postoperative recover smoothly and receive postoperative follow-up about 1 month to 12 years,3 cases of postoperative pulmonary vein stenosis (PPVS) occurred.Conclusion Total anomalous pulmonary venous connection should be surgical treatment as soon as possible with satisfied effect.The key of perioperative care is maintenance of left heart function,negative balance of liquid,prevention and treatment of pulmonary hypertension.

OBJECTIV: e To find the correlation between real best corrected visual acuity (BCVA) and testing results of microperimetry and visual evoked potential (VEP) and to explore a new method in recording BCVA in macular disease. METHODS: Sixty-two patients with macular disease (macular disease group, 62 eyes) and eighteen healthy volunteers (control group, 36 eyes) had BCVA, microperimetry and VEP recorded. RESULTS: (1) By microperimetry, the values of retinal mean sensitivity and fixation percentage in macular disease group were lower than that in control group. The bicurve ellipse area in macular disease group was higher than that in control group. By VEP, P100 amplitude under 0.5 cpd and 2 cpd in macular disease group were significantly higher than that in control group and the latency was prolonged (P < 0.05). (2) In macular disease group, BCVA had significant positive correlation with retinal mean sensitivity, bicurve ellipse area, macular central 2 degrees and 4 degrees fixation percentage, respectively (P < 0.05). There was a significant correlation between retinal mean sensitivity and P100 amplitude (P < 0.05). (3) Multiple linear regression equation was y = 0.053 x1+0.008 x3+3.897 (y was BCVA, while x1 was retinal mean sensitivity and x3 was P100 amplitude under 2 cpd). CONCLUSION Combined use of microperimetry and VEP is useful in the assessment of BCVA in macular disease.

Objective To introduce the treatment of intraarticular calcaneal fractures with poor soft tissue using poking reduction combined with Ilizarov methods. Methods From September 2007 to September 2009,11 patients with the intraarticular calcaneal fractures were treated with poking reduction combined with Ilizarov methods,including 10 males and 1 female at average age of 33.6 years(range,21-50 years).Four patients had the left calcaneal fractures and seven with the right ones.According to Sander classification,there were seven patients with type II fractures,three with type III fractures and one with type IV fracture.The various extents of heel soft tissue injury were emerged in all the patients.Before operation,B(o)hler angle was 0°-12°(average 8°)and Gissane angle 70°-95°(average 80°).According to AO classification of close soft tissue injury,there were three patients with type IC2,six with type IC3,one with type IC5 and one with open soft tissue injury.The collapse of the articular surface was recovered by Steinmann pin which passed through the lateral calcaneal tubercle.The medial and lateral fracture fragments were corrected by using the tensed olive wires.The heighat and width were maintained by using the Ilizarov external fixation. Results The mean duration of follow-up was 13.3 months (range,6-20 months).All fractures were healed after mean duration for 8.1 weeks(range,7-10weeks).The postoperative B(o)hler angle was 20°-45°(average 33°)and Gissane angle 100°-118°(average 107°).According to Maryland Foot Score system,the result of postoperative function was excellent in seven patients,good in three and fair in one,with excellence rate of 91%. Conclusions For the intraarticular calcaneal fractures,the poking reduction combined with Ilizarov method is able to recover and maintain the normal calcaneal height and width and reduce postoperative wound infections and many other complications.specially for Sanders II or III with severe soft tissue injury in the open or closed calcaneal fractures.Master of surgical indications and operating poims can attain satisfactory clinical efficacy.

Objective:To explore the protective effect of vagus nerve stimulation (VNS) on the prognosis of rats suffering from cardiac arrest/cardiopulmonary resuscitation (CA/CPR) under different treatment timings.Methods:The method of percutaneous epicardial electrical stimulation was used to establish CA model of rat. Fifty-three male SD rats were randomly (random number) divided into the sham group ( n=5), CPR group ( n=12), PRE group ( n=12), POST5 group ( n=12) and POST30 group ( n=12). The sham group did not experience CA/CPR. VNS treatment was started at 30 min before CA (PRE group, n=12), 5 min after recovery of spontaneous circulation (ROSC) (POST5 group, n=12), and 30 min after ROSC (POST30 group, n=12) in different VNS-treated group, respectively. The electrical stimulation was applied to the vagus nerve for 30 min with a unified parameter. The neurological deficit scores at 24, 48, and 72 h after ROSC were recorded, and the survival rate in each group was observed. TUNEL staining was used to detect the apoptosis of cortical area and the expression of α7 nicotinic acetylcholine receptor (α7nAChR) in brain tissue was measured by immunofluorescence at 72 h after ROSC. Variables were compared with one-way analysis of variance, and survival for Kaplan-Meier curves were tested with the log-rank test. A P value less than 0.05 was considered statistically significant. Results:Compared with the CPR group (survival rate 33.33%), both pre-treatment (survival rate 75%) and post-treatment of VNS (POST5 group survival rate 75% and POST30 group survival rate 83.33%) significantly improved the 72 h survival rate after CPR ( P<0.05), mitigated neurological deficits after ROSC, reduced the positive rate of apoptosis neurons, and up-regulated the expression of α7nAChR in cerebral cortex. There was no significant difference among the VNS-treated groups (all P>0.05). Conclusions:Both pre-treatment and post-treatment of VNS can play a protective role in rats after CA/CPR, which may be related to the activation of α7nAChR-mediated anti-inflammatory and anti-apoptosis effects.

Objective To characterize the clinical manifestations, laboratory findings of patients with occult sys?temic malignant neoplasms, whose initial manifestation presented as multiple acute cerebral infarcts including coagula?tion function,radiological imaging and microembolic signals (MES) detection by transcranial Doppler sonography (TCD) and to explore the possible underlying mechanisms. Methods All clinical records, laboratory hematological tests includ?ing hypercoagulable states measured by D-dimer levels, brain MRI including DWI, and TCD monitoring MES, the treat?ment and prognosis were retrospectively reviewed in 12 patients with multiple acute cerebral infarcts as the first manifes?tation of occult systemic malignancy. Results The clinical manifestations presented as localized neurological dysfunction, e.g. hemiparesis, aphasia, hemiparesthesia, dysarthria, vertigo and seizures, etc. DWI revealed multiple disseminated acute cerebral infarcts in multiple arterial territories such as the bilateral anterior or anterior plus posterior cerebral circu?lation in all patients. Eleven of 12 patients tested had elevated D-dimer. TCD detected MES in 5 of 7 patients. There were 12 patients diagnosed with occult systemic malignancy including 5 lung cancer, 3 pancreatic cancer, 1 gastric can?cer, 1 colon cancer, 1 endometrial adenocarcinoma and 1 metastatic poorly differentiated mucinous adenocarcinoma with unknown primary. Ten patients already had remote metastasis at diagnosis. The prognosis was usually poor and there were 7 cases with ischemic stroke recurrence, 4 cases with acute myocardial infarction, 3 cases died during hospitaliza?tion. Conclusions When patients present with multiple disseminated acute cerebral infarcts involving multiple arterial territories as initial manifestation, the underlying occult systemic malignancy should be considered. Hypercoagulopathy and MES might provide the clues to the diagnosis.
