AIM: To screen and identify the differentially expressed genes in lymphocytes of patients with unstable angina in order to find the molecular mechanism of unstable angina. METHODS: Suppression subtractive hybridizations (SSH) and dot blot hybridizations were performed to screen the relatively differentially expressed genes in lymphocyte RNA between the patients with unstable angina pectoris and stable angina pectoris. The obtained expressed sequence tags (ESTs) were used as probes to perform Reverse Northern blot with forward and reverse suppression products. And the positive ESTs were performed RNA slot hybridization with unstable and stable angina group. The obtained ESTs were sequenced and analyzed using BLAST (nr) at NCBI. RESULTS: Three up-regulated ESTs in the unstable angina group, and one down-regulated EST in the stable angina group were obtained. All of them are sequences of known genes. CONCLUSION: All these ESTs may be associated with the unstablization of plaque of coronary artery in patients with unstable angina.

Differences of some points, levels and angles of the healthy and affected sides of patients with peripheral facial paralysis were picked out according to photographs. Through analysis of the index between the healthy and affected side of the patients and the difference between healthy people and patients, it is approved that those special points, levels and angles, which are called as deviation index of eye and mouth, can evaluate peripheral facial paralysis objectively and judge the degree of deviation. Therefore, it provides references for the diagnosis of facial paralysis and its degree judgement.

Objective :To construct and identify a ScFv phage display library against human umbilical cord mesenchymal stem cells.Methods: BALB/c mice were immunized with cultured UC-MSCs.After the third immunization,the total RNA was extracted from the spleen cells of the immunized BALB/c mice and purified by affinity chromatography with mRNA Purification Kit.The heavy-chain and light-chain variable region genes(VH and VL) were amplified by PCR using relevant primers.PCR products of VH and VL genes were cloned into the phagemid vector pSEX81 and electroporated into the XL1-Blue strain of E.coli.The ScFv phage display library against human umbilical cord mesenchymal stem cells was constructed and the capacity of library was measured.The library was panned by three cycles and screened with purified UC-MSCs.The percentage of clones containing a full-length scFv-encoding insert and their diversity was determined for unselected and selected libraries.Results: The amplified fragments of VH and VL genes by RT-PCR were about 399bp and 357bp,respectively.VH and VL genes were all successfully cloned into the phagemid vector pSEX81,which were confirmed by the amplication of 786bp full-length scFv fragments by PCR.The ScFv phage display library had a capacity of approximately 2?107 cfu.After three cycles of panning,PCR of plasmid DNA prepared from 15 individual phage clones showed that the recombination rate increased from 93% to 100%.BstN1 fingerprinting of insert DNA showed that the diversity of clones decreased with increasing rounds of selection.After three rounds of selection,3 clones showed an identical restriction enzyme pattern.There was a 330-fold enrichment of library phage after 2 rounds of selection and after 3 rounds,a further 8-fold enrichment of library phage was obtained.Conclusion: The ScFv phage display library against human umbilical cord mesenchymal stem cells was successfully constructed.It can be used for succeeding screening of specific antibody against human umbilical cord mesenchymal stem cells and further studying of the cell surface molecules of mesenchymal stem cells.

Objective To explore the feasibility of percutaneous recanalization by retrograde approach via epicardial collaterals. Methods Retrograde percutaneous coronary intervention (PCI) via epicardial collaterals was performed in 5 patients with previously failed antegrade PCI from April 2009 to November 2009. 7 F guiding catheters were engaged in donor artery. Hydrophilic wires and microcathethers were crossed to the distal ends of chronic total occlusion (CTO) lesions via epicardial collaterals. Four retrograde wires were exchanged into stiffer wires and further crossed the CTO, eventually went into the 6 F antegrade guiding catheters and were jailed by a 2.5 mm balloon. After dilatations of retrograde balloons, the lesions were crossed by antegrade wires, and finalized by conventional PCI method. One case was recanalized with retrograde wire trapping technique and another case was recanalized by reverse CART technique. Results The epicardial collaterals were reached from left anterior descending branch (LAD) to distal right coronary artery( RCA ) via apex in 3 patients, from left circumflex branch via left atrium branch to posterior descending artery and RCA in 1 patient and from obtuse marginal artery to diagonal artery and LAD in 1 patient. CTO was successfully recanalized and stents were implanted in 4 patients and failed in 1 patient despite successful wire positioning to the distal end of CTO. There was no procedure-induced cardiovascular event in all cases. Conclusions Epicardial collaterals may not be used as a routine route in retrograde approach PCI due to the potential risk of myocardial rupture and pericardial tamponade. In some cases with unavailable or unsuitable septal collaterals, epicardial collaterals may be used as an alternative route for CTO recanalization.

OBJECTIVETo evaluate the clinical application value of flexible multi-analyte profiling (xMAP) technology in detecting high-risk human papillomavirus (HR-HPV).

METHODSTotally 1 061 women, aged 21-65 years, were randomly enrolled into the study. Cervical exfoliated cells were used in xMAP technology and hybrid capture II (hc2). Pathological diagnosis was used as golden standard. Consistency of these two methods was assessed.

RESULTSThe sensitivity and specificity of xMAP technology were 80.31% and 85.83%, respectively. The positive and negative predictive values were 44.5% and 96.9%, respectively. The Kappa value for consistency between xMAP technology and hc2 was 0.58.

CONCLUSIONSThe specificity of xMAP technology is similar to hc2 test, but the sensitivity is inferior to hc2. However, these two methods show good consistency in the detection of HR-HPV.

This study was purposed to explore the biological effects suppressing growth and inducing apoptosis of Chinese medicine compound FFJZ on leukemia cell line K562 and its possible mechanisms of FFJZ. The growth status of K562 cells cultured in vitro was determined by trypan blue exclusion test; the suppressive effect of FFJZ on K562 cells was assayed by MTT method; the inducing apoptosis of FFJZ on K562 cells was detected by flow cytometry. The results showed that after K562 cells were treated with FFJZ in certain concentration range, the inhibited rate of FFJZ on K562 cell growth was remarkably increased along with enhancement of FFJZ, the IC(50) value of FFJZ on K562 cells was 5.6 mg/ml after treatment for 48 hours. At 4 mg/ml of FFJZ the early apoptosis predominated in K562 cells, at 8 mg/ml of FFJZ the late apoptosis ratio significantly increased. As compared with control group without FFJZ, there was significant difference (p < 0.01). It is concluded that the FFJZ in range of certain concentration can suppress growth and proliferation of K562 cells and induce their apoptosis in concentration-dependent manner, the mechanism of which may be associated to inducing apoptosis of K562 cells.

BACKGROUNDIn humans telomerase is expressed in most cancers and immortal cell lines, and activation of telomerase may play important roles in tumorigenesis and immortalization. This study was to investigate the roles of telomerase activity (TA) and human telomerase RNA (hTR) in sebaceous carcinoma of the eyelid.

METHODSThe telomerase repeated amplification protocol (TRAP) was used to demonstrate telomerase activity in 12 cases of sebaceous carcinoma of the eyelid. In situ hybridization (ISH) was used to demonstrate the expression of hTR in 55 cases of paraffin-embedded sebaceous carcinoma of the eyelid, and the results were compared with the proliferative index determined by Mib-1 immuno-labeling, histological patterns and recurrence of the tumor.

RESULTSDifferent telomerase activity was shown in the 12 cases of sebaceous carcinoma of the eyelid. The positive expression of hTR was 85.5% (47/55) in tumor cells, but not in the adjacent tissues. The positive expression of hTR was correlated with the proliferative activity (as assessed by Mib-1 immunolabelling, r = 0.942, P < 0.001) and the differentiation of sebaceous carcinoma of the eyelid (chi(2) = 17.621, P < 0.001), but not significantly related to tumor recurrence. The level of hTR expression increased with the decrease of differentiation of sebaceous carcinoma of the eyelid.

CONCLUSIONSThe results suggest that the up-regulation of telomerase expression plays some roles in tarsal gland carcinogenesis, and the expression of hTR is a useful marker for malignant degree of sebaceous carcinoma of the eyelid.

BACKGROUNDSurgical interventions for moyamoya disease include direct and indirect revascularizations. This study aimed to evaluate the therapeutic effect of superficial temporal artery-middle cerebral artery bypass combined with an indirect revascularization procedure, encephalo-duro-myo-synangiosis, in the treatment of moyamoya disease.

METHODSFrom October 2005 to November 2009, we performed this combined revascularization procedure in 111 patients with different types and stages of moyamoya disease. The superficial temporal artery, middle meningeal artery and the deep temporal artery were evaluated for individualized surgical planning in these cases. The integrity of the deep temporal artery and the middle meningeal artery network, and the pre-existing spontaneous anastomoses of the distal branches of the external carotid artery with the cortical arteries were well preserved. The mean follow-up time was 72.5 months, all clinical and radiological data were retrospectively reviewed.

RESULTSA total of 198 stomas were performed in 122 hemispheres, all remaining patent until the last follow-up. The encephalo-duro-myo-synangiosis resulted in extensive anastomoses of the deep temporal artery (100%), the middle meningeal artery (90.9%), and the sphenopalatine artery (39.8%) with the cortical arteries, respectively. The superficial temporal artery, deep temporal artery, and the middle meningeal artery were significantly thickened in 88 patients as determined by digital subtraction angiography at follow-up. The relative cerebral blood flow increased significantly within one week after the operation. At 6 months post the operation, the relative cerebral blood flow was further increased by 15.5% from the gradual formation of anastomoses as a result of indirect revascularization. Transient ischemic attacks were effectively reduced or totally arrested. The neurological deficits significantly improved in 37 patients, with the National Institutes of Health Stroke Scale scores lowered by 2-8. There was no rehemorrhage in hemorrhagic moyamoya disease patients.

CONCLUSIONThis study showed that the superficial temporal artery-middle cerebral artery bypass combined with encephalo-duro-myo-synangiosis can achieve good therapeutic effect in the treatment of moyamoya disease.
