Needlescope is a laparoscopic equipment with a diameter of only 2 mm. It has been used in treatment of some general surgery and gynecology diseases. In urology .needlescopic techniques have also been applied in some procedures including adrenalectomy and pediatric orchiopexy. Although debates still exist about the definition of needlescopic surgery and the 2-mm instruments have their limitation,needlescopic technology has obvious advantages such as smaller traumas,superior cosmetic result, shorter hospital stay, and abbreviated convalescence. Needlescopic techniques represent a natural evolution of conventional laparoscopy.

Objective To observe the levels of plasma high sensitive C-reactive protein (hs-CRP) and brain natriuretic peptide (BNP) in patients with ST-segment elevation myocardial infarction ( STEMI)and analyze their significance. Methods This study enrolled 80 patients who had first acute STEMI. Twenty-five patients were in the primary percutaneons coronary intervention (PCI) group, 27 patients were in the delayed PCI group and 28 patients were in the medical treatment group. The levels of hs-CRP, BNP and creatine kinase MB (CK-MB) were measured after treatment. Left ventricular function and ventricular wall thinning ratio were evaluated by echocardiography. Results The levels of plasma hs-CRP showed dynamic variation with time in all patients. The peak time of hs-CRP was significantly different among the three groups. The peak value of hs-CRP, BNP, wall motion score index ( WMSI ) and the incidence of left ventricular remodeling decreased, but the level of loft ventricular ejection fraction (LVEF) increased in the primary PCI group. Compared with the delayed PCI group and the medical lreatment group, there were significant difference. Correlational analysis showed that there were negative relationship between LVEF and hs-CRP, BNP,WMSI (r = -0.895, -0.940, -0.939,P < 0.01 ) and positive relationship between hs-CRP and BNP, CK-MB (r = 0.935,0.886, P < 0.01 ). Conclusions The associated measure of hs-CRP and BNP could preferably evaluate the inchoate prognosis of STEMI. hs-CRP might be an useful index of successful reperfusion and predict the stability of infarction related lesion.

Objective To observe feature of clinic and imageology in patients with unstable angina pectoris after radiation therapy to chest. Methods The study enrolled 58 patients who had unstable angina pectoris. Twenty-eight patients were in the postradiation therapy to chest group, 30 patients were in the common unstable angina pectoris group. All patients underwent multislice spiral CT(MSCT) examination and coronary angiography (CAG). After one year follow-up, the levels of brain natriuretic peptide (BNP) and ventricular wall motion score index (WMSI) were measured , the incidence of cardiovascular events were observed in all patients. Results Calcific, multi-vessel, thrombotic disease and dissection were significantly different between the two groups, when one year follow-up , the levels of BNP were higher in the postradiation therapy to chest group than those in the common unstable angina pectoris group [ (234.31 ± 121.39) ng/L vs (124.74 ±37.81) ng/L] WMST, incidence of the first heart failure, angina pectoris recurrence and revascularization were significantly different too (P< 0.05 ). Conclusions The complex lesions are major in the postradiation therapy to chest. Moreover, because radiation injures the heart valves and myocardium,these patients' long-term prognosis are worst.

Objective To evaluate the agreement between colposcopic diagnosis with 2011 colposcopic terminology of the International Federation for Cervical Pathology and Colposcopy (IFCPC) and cervical pathology in cervical lesions. Methods A retrospective cohort study was performed, which included 376 patients who underwent colposcopy with 2011 international terminology of colposcopy at Obstetrics and Gynecology Hospital of Fudan University from September 2014 to November 2014. With conization or cervical biopsy pathology as the gold standard, the agreement between colposcopic diagnosis and pathologic diagnosis was calculated and correlations between variables were analyzed. Results With 2011 international terminology of colposcopy, agreement of colposcopic diagnosis and cervical pathology was 60.9%(229/376)perfectly matched, and the strength of agreement with weighted Kappa statistic was 0.401 (P<0.01), and agreement within one grade was 97.6%(367/376), which were improved compared with traditional methods. Colposcopic diagnosis were 19.9%(75/376) overestimated and 19.1%(72/376) underestimated. There were no significant difference between agreements in various grade lesions (χ2=1.996, P=0.573). Positive predictive value of high grade colposcopy or more was 84.4%, the negative predictive value of low grade colposcopy or less was 88.8%, whereas false positives were 3.5%and false negatives were 39.3%. A linear trend among three types of transformation zone and patient ages was found (χ2=45.910, P<0.01), whereas lesion sizes were not linearly correlated with lesion degrees (χ2=0.690, P=0.406). In grade 1, grade 2 and nonspecific findings, thin acetowhite epithelium, dense acetowhite epithelium and Lugol′s non-staining were most frequent, the Youden indexes of each were 0.170, 0.373 and 0.145, 0.069 respectively. Positive predictive value of some other findings (such as fine mosaic) and two new signs (inner border sign and ridge sign) were 100.0%. There were no significant difference between agreements in examiners with different levels of experience (χ2=1.197,P=0.550). Conclusions Compared to traditional methods (such as Reid index), 2011 international terminology of colposcopy could improve the agreement between colposcopic diagnosis and pathologic diagnosis, without significant differences by the severity of lesion and the level of examiners′experience. Common findings were classified reasonably, and some signs were highly reliable, which is important for guiding biopsy. However, the reproducibility of transformation zone types and the implication of lesion size need to be further discussed.

Objective To explore what kind of role serum interleukin 6 (IL-6) and interleukin 18 ( IL-18) play in the relationship between type D personality and acute coronary syndrom (ACS)prognosis.Methods Serum levels of IL-6,IL-18 in all 214 ACS patients were measured with ELISA.According to the scores of type D personality scale(DS14) ,the subjects were divided into the group with type D personality (50 cases)and the one without type D personality ( 164 cases).The serum IL-6 and IL-18 level between the two groups were detected and analyzed.Results There were 23.36% ACS patients with type D personality.The serum IL-6, IL-18levels of the group with type D in ACS acute stage and ACS recovery stage were (2.340 ± 0.081 )OD, (2.016 ±0.023 ) OD and ( 1.460 ± 0.070 ) OD, ( 1.313 ± 0.012 ) OD respectively, significantly higher than those of the group without type D (2.178 ± 0.180)OD, ( 1.849 ± 0.159)OD and ( 1.387 ± 0.091 )OD, ( 1.196 ± 0.132 ) OD respectively(P＜0.01).Conclusion At home and abroad ,there are similar amount of ACS patients with type D personality.The high serum IL-6 and IL-18 levels may play an important role in pathogenesis of relationship between type D personality and ACS poor prognosis.

Honeybee pupae were collected from Jilin apiaries and RNA was extracted for use as a tefnplate for amplification. Based on the complete genome sequences of black queen cell virus (BQCV) published on GenBank, we designed 10 pairs of primers to amplify genes by reverse transcription-polymerase chain reaction (RT-PCR). Using this approach, we have obtained the first complete genome sequence of a BQCV isolate in China. The genome of the isolated strain, named BQCV-JL1, is composed of 8358 nucleotides and shares between 86% and 93% homology with the complete genome sequences of the other six BQCV strains published on GenBank. ORF 1 of BQCV-JL1 is positioned between nucleot ides (nt) 546 and 4676 (4131 nt), while ORF 2 is located between nt 5750 and 8203. Between the two ORFs of BQCV-JL1 there is a short ORF, called ORF 3, between nt 4891 and 5433 (543 nt). The first functional gene ex- pression domain of the BQCV-JL1 strain is positioned between nt 546 and 5 429, encompassing both ORF 1 and ORF 3. There is an internal ribosome entry site (IRES) located before ORF 2, the last three bases of which are CCU (nt 5642-5644). These bases act as an initiation.codon facilitating the translation of ORF 2. The second functional gene expression domain of the BQCV-JL1 strain is located between nt positions 5642 and 8203. The BQCV-JL1 strain was found to share high sequence identity (93%) with the Hungary 10 genotype at the whole-genome level and analysis of the nucleotide and amino acid sequences revealed that the BQCV-JL1 strain also shows close genetic relationships with the South Korea strain, suggesting that both the BQCV-JL1 and South Korea strains may have migrated from European countries. BQCV-JL1 strain was different from the other 6 strains in dividing the nucleotides positions of QRF, which vqs because of the gene mutation.

In nature, honeybees are the most important pollinators. They play a vital role in both protecting the diversity of natural ecosystems, and maintaining the yield-improving effects of agroecosystems. But in recent years, epidemic disease in bees has caused huge losses. Black Queen Cell Virus (BQCV) is a bee pathogen that was first reported in 1955. It mainly infects bee larvae and pupae, making their bodies turn dark and black, and causing a massive decrease in the bee population. More specifically, the virus makes the exterior of the cell walls in the larvae and pupae turn black. BQCV is a seasonal epidemic, spread by means horizontal and vertical transmission, and is often unapparent. BQCV not only infects a variety of bee species, but also spiders, centipedes and other arthropods. It can also be coinfected with other honeybee viruses. In recent years, research has shown that the Nosema intestinal parasite plays an important role in BQCV transmission and bees carrying Nosema that become infected with BQCV have increased mortality. Here we summarize current research on the incidence, prevalence, geographical distribution and transmission of BQCV.
