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 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 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 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.

Objective To explore the sensitivity and specificity of colposcopy directed biopsy (CDB) and the value of loop electrosurgical excision procedure (LEEP) for the diagnosis and treatment of microinvasive cervical cancer (MCC). Methods One hundred and thirty five patients with MCC were diagnosed with LEEP in Obstetrics and Gynecology Hospital, Fudan University from April 2008 to November 2010, and were retrospectively analyzed on CDB diagnoses and following treatment after LEEP. According to patient′s desire for preservation of fertility and cone margin status, following strategies after LEEP included follow-up, second LEEP, hysterectomy, modified radical hysterectomy and radical hysterectomy. Single and multiple factors related to residual lesions after LEEP were analysed with Pearson Chi-square test and logistic regression model, respectively. Results CDB diagnosed MCC with a sensitivity of 4.4%(6/135), specificity of 100.0%(4 680/4 680), and false negative rate of 95.6%(129/135). Among the 135 patients, 29 did not receive further treatment in our hospital and lost contact. One hundred and six patients had secondary treatment or follow-up in our hospital, 4 of among which were closely followed up;one hundred and two received further treatment, which included 6 cases with second LEEP (3 received extrafascial hysterectomy after repeat LEEP), 59 cases hysterectomy, 14 cases modified radical hysterectomy and 26 cases radical hysterectomy. For factors related to residual lesions after LEEP, single factor analysis showed that the ratio of residual lesion in patients aged 27-39, 40-49 and 50-65 years were respectively 19.0%(11/58), 15.4%(10/65) and 5/12 (χ2=4.505, P=0.105). Residual lesions occurred in 24.7%(23/93) of patients with positive LEEP margins, which was more than that 7.1%(3/42) of patients with negative LEEP margins (χ2=5.756, P=0.016). The ratio of residual lesions in patients with positive endocervical, ectocervical and deep stromal margins were respectively 29.6%(8/27), 17.1%(7/41)and 30.6%(11/36;χ2=2.275, P=0.321). Residual lesions in patients with or without lymph vascular space invasion (LVSI) were 2/7 and 18.8%(24/128), respectively (χ2=0.412, P=0.521). The ratio of residual lesions in patients with invasion depth of<1 mm was 17.1%(7/41), 1-<3 mm was 19.0%(16/84), and 3-5 mm was 3/10, with no significant difference among three groups (χ2=0.870, P=0.647). Logistic regression analysis showed positive cone margin (OR=5.069, P=0.014) and age (OR=1.080, P=0.024) were the independent risk factors of residual lesions after LEEP conization. Conclusions CDB alone is not adequate for the diagnosis of MCC. For young patients who desire to preserve fertility with a negative cone margin, close follow-up is acceptable. Cone margin status and age are two independent risk factors for residual lesions after LEEP.

Objective To evaluate the anticonvulsant effect of midazolam and diazepam when administered nasally on maximal electroshock seizure and metrazol seizure threshold test models .Methods Rats were randomly divided into 7 groups:model group, low-dose, middle-dose and high-dose of midazolam nasal spray groups , diazepam nasal spray in low-dose, middle-dose and high-dose of midazolam nasal spray groups .After the establishment of the maximal electroshock seizure( MES) and metrazol seizure threshold test models ( MST) in rats, the anticonvulsant effects of different doses of midazolam and the clinically used antiepileptic drug diazepam were evaluated and compared .HE staining was used to observe the histopathological changes in the hippocampus , cortex and amygdala in rats .Results Significant anticonvulsant effects were observed on MES and MST in rats pretreated with different dosages of midazolam .In addition , the anticonvul-sant effects of midazolam were stronger than those of diazepam at the same dosage on MES and MST (P<0.05,P<0.01). Histopathological results showed that both midazolam and diazepam could effectively prevent the seizure -induced brain inju-ries, inhibit the increase of microglial cells and the inflammatory cell infiltration in the hippocampus, cortex and amygdala, and reduce the nucleus pycnosis and neuronophagia .Conclusion Midazolam has significantly anticonvulsant and neuropro-tective effects on different seizure models when administered nasally in rats .

Objective To explore the mechanism of Zibu Piyin Recipe (ZBPYR) on spleen yin deficiency diabetes-associated cognitive disorder (DACD). Methods The rats were randomly divided into control group, diabetes mellitus (DM) group, spleen yin deficiency group, spleen yin deficiency DM group and spleen yin deficiency DM+ZBPYR group (treatment group). Type 2 DM models were established by high-fat food feeding and low dose STZ intraperitoneal injection for 4 weeks. Then the classical compound method was used to construct spleen yin deficiency rat models by improper diet, over exertion and yin fluids exhaustion. The treatment group was given ZBPYR by gavage for 15 days, and the other groups were given the same amount of normal saline. Then cerebral cortex, hippocampus, stomach and liver were obtained and the changes of protein expression of PDHE1α in them were observed by Western Blot. Results The protein expression of PDHE1αin cortex of DM group and spleen yin deficiency DM group were lower than control group (P<0.05). PDHE1α expression of treatment group in cortex and stomach increased more significantly than spleen yin deficiency DM group (P<0.05). The expression of PDHE1α protein showed no significant difference among all groups in hippocampus and liver. Conclusion ZBPYR improved spleen yin deficiency DACD by regulating PDHE1αin cortex and stomach.

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.
