Objective Based on the Helical Ventricular Myocardial Band (HVMB) theory proposed by Torrent-Guasp,the ventricular myocardial hand extends from the root of the pulmonary artery to the root of the aorta with two helical coils.This new theory is considered as a revolutionary concept for further understanding the global, three-dimensional and functional architecture of the ven- tricular myocardium. No repot had described techniques for disecting HVMB while keepin～ the integrity of the coronmy artery sys- tern. We explored techniques for dissecting HVMB in swine.Methads 33 fresh swine hearts were randomly divided intoll groups, 3 bearts in each. 160% barium sulfate (type I)suspmmion was injected into the coronary artery system. The coronary arteries were li- gated. The strial tissue was removed following puuing the hearts in boiling water then cooling for several hours. The superficial coro- nary vessels and fat tissue around the atrio-ventricular taxi inter-ventricular sulcus we～'e preserved. Some branches of the left anterior descending artery, distal segment, of posterior descending branch, and middle and distal segment of obtuse marginal branches were mu- tilated appropriately. HVMB dissection was completed with fingers in accordnce with Torrent Guasp' s technique. Results A contin- ued bundle of muscle, originated at the root of pulmonary artery and ended at the root of aorta, was unwrapped along the major dire- tion of the cardiac muscle fiber in all of the 33 hearts with spating of the coronary artery. The swine hearts' ventricular myocandium was cumosed of two loops, with basal loop firm the root of the pulmonart artery to the anterior papillary muscle and apical from the beginning of the anterior papillary muscle to the root tithe aorta. Each loop consisted of two segments: the right segment-coincid- ing with the right ventricular free wall and the left segment-coinciding with the basal d the left ventricular free wall. Posterior papillary muscle, which belongs to the descendant segment, denmrcated the border between the descendent and the ascendant of the HVMB's apical loop. Conclusion Although controversies about the theory of the HVMB remain, we have dissected the HVMB in the swine hearts' ventricular myocardium successfully with sparing of the coronary artery systems. This dissection procedure provides technical information for the studies of associated diseases based on the theory of HVMB.

Objective An epitope in E1 region of hepatitis C virus (HCV) was constructed and highly expressed in a foreign epitope presenting vector based on an insect virus, flock house virus capsule protein encoding gene as a vector. Methods Using genetic engineering techniques, an epitope in E1 region of HCV was constructed in a foreign epitope presenting vector based on an insect virus, flock house virus capsule protein encoding gene as a vector and lastly constructed a chimeric gene. The chimeric gene can be put into an expressing plasmid, and expressed in either eukaryotic or prokaryotic system. The foreign epitope can be expressed in this system on the surface of the vector stereotic structure with its native conformation, and which can improve its immunogenecity. Results An epitope in E1 region of HCV was successfully cloned in three positions (aa106、aa153、aa305) of a foreign epitope presenting system based on an insect virus, flock house virus capsule protein encoding gene as a vector.The recombinant epitope in this system could be highly expressed more than 40% of total cell protein in E.coli.BL21 cell in somewhat strict conditions without IPTG inducing. Conclusions We have made this chimeric gene highly expressed in E.coli.BL21, by the way different from routine method. The results suggest that the expression method and this epitope presenting system can be used in studying immunological and biological properties of HCV and developing diagnostic reagents as well as epitope-based subunit vaccines for controlling HCV infection.

Thyroid-like papillary adenocarcinoma is an extremely rare neoplasm in the nasopharynx. We present a case with a pedunculated tumor in the nasopharyngeal vault. Complete tumor resection via nasal endoscopy was performed subsequently. Postoperative histopathological examinations and immunohistochemical studies confirmed the diagnosis of thyroid-like papillary adenocarcinoma. This rare neoplasm demonstrated a distinct etiology and nature from typical nasopharyngeal carcinomas and should be managed mainly by surgical resection.

Objective To explore the variation of serum D-lactic acid levels and the correlation between different intestinal viral and intestinal barrier function in children with hand, foot and mouth disease (HFMD). Methods The stools of 129 children with HFMD were collected and were detected by reverse transcription polymerase chain reaction. The children were divided into four groups according the fecal pathogens detection:enterovirus 71 (EV71) positive group, Coxsackie virus A16 (CoxA16) positive group, other intestinal virus positive group (EA positive group), and no intestinal virus group (EA negative group). Two ml venous blood and separation serum was collected in each group of children, and the level of serum D-lactic acid was detected further. Results There were 20 cases of other Coxsackie virus, and they were not grouped. Fifty-seven patients were in EV71 positive group, 26 patients were in CoxA16 positive group, 10 patients were in EA positive group, and 16 patients were in EA negative group. The level of D- lactic acid in four groups was 26.28 (17.02- 58.01), 14.43 (8.93- 20.66), 10.66 (6.64- 18.51) and 14.07 (11.83- 27.46) mg/L. The results of rank test showed the level of D-lactic in EV71 positive group was significantly higher than that in EA positive group (Z=-2.432, P=0.015) and EA negative group (Z=-3.092, P=0.002). Conclusions D-lactic acid level increases significantly in EV71 infection children and suggests that the illness is more serious and the intestinal barrier is damaged. Doctors should pay more attention to monitor and protect gastrointestinal function of children with HFMD.

Objective To observe the feasibility, safety and efficacy of percutaneous coronary intervention (PCI) for treatment of chronic total occlusions (CTO)by only the guidewire versus by the guidewire dependent on balloon. Methods The 108 patients with CTO confirmed by coronary angiography and treated with PCI from March 2009 to March 2011 were enrolled in this study, including 59 cases with old myocardial infarction, 22 unstable angina cases and 27 stable angina cases. The clinical data, outcomes of PCI, perioperative complications and incidence of major adverse cardiac events (MACEs) during follow-up were retrospectively analyzed between group A (only by the guide wire) and group B (by guide wire dependent on balloon). Results The 88 of 108 patients (81.5%) got successful operations. The success rate of CTO was a little higher in group B than in group A [80.0%(52/65) vs. 83.7%(36/43), P＞0.05]. The rate of total complications was more in group A than in group B [10.8%(7/65) vs. 2.3%(1/43), P＜0.05]. No death occurred during operation, no MACE occurred after operation in hospital and no patients underwent emergency coronary artery bypass graft (CABG) in the two groups. Conclusions The PCI for treatment of CTO used by the guidewire dependent on balloon shows a safety and effecary.

Objective To investigate the effect of apoptosis-related gene p53 on the apoptosis of retinal capillary cells in rats with spontaneously hypertensive (SHR) after ischemic reperfusion injury. Methods A total of 60 SHR rats were randomly divided into sham group (SHR-SH) and retinal ischemie reperfusion group (SHR-RIR), which were subdivided into 5 subgroups according to the time after RIR: 2, 6, 24, and 72 hours and 7 days, with 6 rats in each subgroup. Another 60 Wistar-Kyoto (WKY) rats were divided into the same groups as the SHR rats as the control. The RIR model was set up. The apoptosis of retinal capillary cells was detected by terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) methods and the expression of p53 was determined by streptavidin-perosidase (SP) immunohistochemistry. Results The apoptosis rate of retinal capillary cells in the 5 SHR-RIR groups was (8.64±0.56)%, (14.92±0.99)%, (24.72±2.98)%, (16.53±1.80)%, and (7.12±1.10)%,respectively. The expression of p53 in SHR-RIR groups increased at the 2nd hour after RIR, reached the peak at the 24th hour, kept the high level at the 72nd hour, and remained a little at the 7th day, which was significantly different from which in the SHR-SH groups (P<0. 01). The expression of p53 were higher in SHR-IR groups than that in the WKY-RIR groups (P<0. 01). Conclusions p53 may play a part in RIR injury by inducing or promoting apoptosis. The apoptosis of retinal capillary cells after RIR is more severe under the hypertension, and reaches the peak at the 24 hour after RIR.
