Objective To study clinical effects and complications of minimal invasive neurosurgery for pituitary adenoma through superciliaryarch-keyhole approach. Methods 127 cases pituitary adenoma in three hospitals in Shangdong province from May. 2006 to Sept. 2009 confirmed by surgery were analyzed. Patients were treated by different operative approaches, 53 cases using surgery through superciliaryarch-keyhole approach and 74 cases through conventional subfrontal approach. Clinical parameters were compared in patients undergoing surgery through different approaches. Results There were no differences in two groups, in aspects such as resection rate, improvment of endocrine hormone secretion and acuity of vision with campus visualis, electrolyte disturbances, hypothalamus damage (P ＞0.05). Significant differeces reside in average hospitalization days, subcutaneous fluidify, psychiatric symptom and circumscribed cerebral ischemia ( P ＜ 0.05 ). Conclusion Advantages of minimal invasive neurosurgery through superciliary arch approach such as less trauma, better expose,shorter hospitalization days, less subcutaneous fluid accumulation and psychiatric symptoms in terms of this apporach are suitable for removing hypophyseal adenomas that grow on or around sella turcica.

ObjectiveTo investigate the association of phosphorylation of mammalian target protein of rapamycin (pmTOR) expression with glioma malignancy grades,and the correlation of pmTOR expression with Survivin and Ki-67,which represent tumor cell anti-apoptosis ability and reproductive activity.MethodsImmunohistochemistry EliVision method was employed to detect the expression of pmTOR,Survivin and Ki-67 in paraffin tissues from 87 patients with glioma (grade Ⅰ - Ⅱ 27 cases,grade Ⅲ24 cases and grade Ⅳ 36 cases).The association between positive expression rate,level of pmTOR and malignancy grades,and the correlation of its expression level with Survivin and Ki-67 were further evaluated.Results There was no significant difference in the positive expression rate of pmTOR among grade Ⅰ - Ⅱ(77.8％,21/27),grade Ⅲ(75.0％,18/24) and grade Ⅳ (72.2％,23/36) (P ＞ 0.05).However,the significant association between pmTOR expression level and malignancy grades was observed.The expression from 87 patients with glioma was significantly positively correlated with Survivin and Ki-67 expression level (r =0.858,P ＜ 0.01 ;r =0.708,P ＜ 0.01 ).ConclusionsThe expression level of pmTOR is associated with malignancy grades,tumor cell anti-apoptosis ability and reproductive activity.pmTOR may be served as a useful marker for predicting the biological behavior of glioma and a useful target for gene therapy.

Objective To observe the effect of one-lung ventilation (OLV) on cerebral oxygen balance and energy metabolism during total intravenous anesthesia for thoracoscopic surgery.Methods Thirty patients scheduled for thoracoscopic surgery were selected.After inducing and intubating,patients were assigned to maintenance of anesthesia with propofol by target controlled infusion in order to maintain a bispectral index(BIS) between 40 and 60,and end-tidal partial pressure of carbon dioxide (PETCO2) between 30mmHg and 35mmHg.Mean arterial pressure (MAP),heart rate (HR),SpO2,PetCO2,cerebral blood flow velocity (CBFv),BIS value and nasopharyngeal temperature(NPT) were measured,always with the patients in the lateral position,in four phases:10min after beginning twolung ventilation (TLV),15 min after beginning OLV (OLV + 15),30min after beginning OLV (OLV + 30) and 60 min after beginning OLV(OLV + 60).Blood samples were drawn simultaneously and analyzed within 5min.The Da-jvO2,CERO2,CMRO2,Da-jvLac and Da-jvGlu at each phase were calculated.Results In all patients,a decrease in PaO2 [(172±85) vs (428±42);(162±54) vs (428±42);(185±61) vs (428±42)] and MAP [(70±10) vs (81 ±11) ; (71 ± 12) vs (81 ± 11)] occurred during OLV (t =15.02,13.14,23.25,20.16,18.02,all P ＜ 0.05).SjvO2 at the phase:OLV + 15 and OLV + 30 were significantly lower than those at TLV [(54.0 ± 1.2) ％ vs (65.0 ± 0.8) ％ ;(55.0±1.5)％ vs (65.0 ±0.8)％] (t =3.12,2.14,all P＜0.05).Ca-jvO2[(50 ± 12)％ vs(40 ± 12)％ ;(54±11)％ vs (40 ± 12)％],CMRO2 [(186 ±40) vs (162 ± 35);(191 ±24) vs (162 ±35)]and CERO2 [(36 ± 12) vs (30 ± 1 1) ; (35 ± 10) vs (30 ± 11)] atthephase:OLV + 15 andOLV + 30weresignificantlyhigher than those at TLV (t =5.23,4.28,1.86,2.01,8.21,10.11,all P ＜ 0.05).After OLV,Da-jvGlu [(0.45 ± 0.10) vs (0.22 ± 0.30) ; (0.52 ± 0.20) vs (0.22 ± 0.30) ; (0.40 ± 0.20) vs (0.22 ± 0.30)] significantly increased (t =6.45,12.03,15.10,all P ＜ 0.05).The differences of Da-jvLac and CBFv at every phase were not significant (P ＞0.05).Conclusion During total intravenous anesthesia,OLV resulted in an increase of consumption of cerebral oxygen and energy.It may be not good for cerebral oxygen balance and energy metabolism.The efficient prevention is necessary clinically.

Objective To investigate the diagnosis and treatment in patients with acute myocardial infarction (AMI) and complicated left ventricular wall rupture (LVWR). Methods A retrospective analysis was made on the clinical features, diagnosis and successful treatment in three AMI patients with LVWR from December 2015 to April 2016. Results Three cases were included in this study. Case 1, the mesh like cardiac rupture after AMI was diagnosed by ultrasonic Doppler. Emergency revascularization was performed due to the combined cardiac shock, and the infarct related artery was opened. The vasoactive drugs were used after revascularization to reduce ventricular pressure load and volume load in the haemodynamic monitoring, and anticoagulation, antiplatelet agents were less used or discontinued to promote local thrombus healing of ventricular rupture. Case 2 was a recurrent myocardial infarction patient. LVWR was diagnosed by ultrasonic Doppler one day after emergency operation. The ruptured ventricular wall was encapsulated by thrombus. The drug therapy was effective in hemodynamic monitoring. LVWR was further confirmed by cardiac CT after clinical stabilization. Case 3 was diagnosed LVWR by ultrasonic Doppler four days after AMI. Because the ruptured ventricular wall was limited by incompletely organized thrombus, and the haemodynamic condition was stable, selective surgical repair of rupture after coronary angiography was performed. Conclusion The effective drug therapy combined with percutaneous coronary intervention and surgical repair can reduce the risk of death in patients with LVWR after AMI.

Objective: : Kinesin family member C1 (KIFC1), a non-essential kinesin-like motor protein, has been found to serve a crucial role in supernumerary centrosome clustering and the progression of several human cancer types. However, the role of KIFC1 in glioma has been rarely reported. Thus, the present study aimed to investigate the role of KIFC1 in glioma progression. Methods: : Online bioinformatics analysis was performed to determine the association between KIFC1 expression and clinical outcomes in glioma. Immunohistochemical staining was conducted to analyze the expression levels of KIFC1 in glioma and normal brain tissues. Furthermore, KIFC1 expression was knocked in the glioma cell lines, U251 and U87MG, and the functional roles of KIFC1 in cell proliferation, invasion and migration were analyzed using cell multiplication, wound healing and Transwell invasion assays, respectively. The autophagic flux and expression levels matrix metalloproteinase-2 (MMP2) were also determined using imaging flow cytometry, western blotting and a gelation zymography assay. Results: : The results revealed that KIFC1 expression levels were significantly upregulated in glioma tissues compared with normal brain tissues, and the expression levels were positively associated with tumor grade. Patients with glioma with low KIFC1 expression levels had a more favorable prognosis compared with patients with high KIFC1 expression levels. In vitro, KIFC1 knockdown not only inhibited the proliferation, migration and invasion of glioma cells, but also increased the autophagic flux and downregulated the expression levels of MMP2. Conclusion : Upregulation of KIFC1 expression may promote glioma progression and KIFC1 may serve as a potential prognostic biomarker and possible therapeutic target for glioma.

Objective:To explore the mechanism of Gynostemma pentaphyllum in the treatment of atherosclerosis (AS) based on network pharmacology. Methods:TCMSP was used to analyze the chemical components and targeted effect of Gynostemma pentaphyllum, through the database like OMIM, TTD, drugbank and digsee to predict and screen the targeted effect of AS. The genes corresponding to the target were queried by UniProt database, and then the compound target (gene) network and protein-protein interaction network (PPI) were constructed by using Cytoscape 3.2.1 to screen out the core target. Finally, the function enrichment analysis of Gene Ontology (GO) and the pathway enrichment analysis based on Kyoto Encyclopedia of genes and genomes (KEGG) were carried out by David, and the mechanism of action was studied. Results:The compound-target network consisted of 13 compounds and 150 corresponding targets. The key targets were PGR, NR3C2, NCOA2, PPARG, PTGS1, PTGS2, etc. PPI network contains 131 proteins and 46 core proteins. There are 480 GO item in GO function enrichment analysis, including 403 entries in biological process (BP), 35 entries in cell composition (CC), and 42 entries in molecular function (MF). 25 signaling pathways related to AS were obtained by enrichment and screening of KEGG pathway, involving PI3K-AKT, TNF, HIF-1, MAPK, toll like receptor and other signaling pathways.Conclusions:This paper discussed the mechanism of Gynostemma pentaphyllum in the treatment of AS through network pharmacology, which provides new ideas and methods for further research and exploration of the mechanism of Gynostemma pentaphyllum in the treatment of AS.

Objective     To compare the clinical effects of coronary artery bypass grafting (CABG) via the left anterior small thoracotomy (LAST) versus lower-end sternal splitting (LESS) approach in the treatment of coronary heart disease. Methods     The patients who underwent LAST CABG in Tianjin Chest Hospital from October 2015 to December 2020 were allocated to an observation group (LAST group), and the patients who underwent LESS CABG at the same period were allocated to a LESS group. Propensity score matching method was applied with a ratio of 1∶1. The baseline data, perioperative data and grafts data were compared between the two groups after matching. Results     Before matching, there were 110 patients in the LAST group, and 206 patients in the LESS group. After matching, there were 110 patients in each group. In the LAST group, there were 83 males and 27 females with an average age of 60.6±8.3 years. In the LESS group, there were 80 males and 30 females with an average age of 61.0±9.6 years. There was no statistical difference in baseline data between the two groups after matching (P>0.05). The hospital stay time (t=2.255, P=0.025) and ventilator using time (t=−2.229, P=0.027) in the LAST group were significantly shorter than those in the LESS group. There were no statistical differences between the two groups in the postoperative hospital stay time, ICU stay time, postoperative left ventricular ejection fraction, postoperative left ventricular end-diastolic diameter, average number of grafts, secondary intubation, secondary thoracotomy, postoperative wound infection, sternal complications, postoperative atrial fibrillation, postoperative pulmonary infection or main adverse cardiovascular and cerebrovascular events (P>0.05). There was no statistical difference in the distribution of target vessels in the anterior descending branch, diagonal branch or posterior descending branch between the two groups (P>0.05). The grafts of the LAST group were significantly more than those of the LESS group in the area of obtuse marginal branch and posterior ventricular branch, and the grafts of the LESS group were significantly more than those of the LAST group in the area of right coronary artery (P<0.05). Post-operative computerized tomography angiography indicated that 1 patient in the LAST group had obtuse marginal branch vein bridge vessel occlusion, and the bridge vessels in the other patients were unobstructed. Conclusion     Minimally invasive CABG via both LAST and LESS approaches is safe and effective. LAST approach can achieve complete revascularization for multi-vessel lesions, and it is safe and reliable, with the advantages of less trauma and aesthetic appearance. However, it requires a certain learning curve of surgical techniques and certain surgical indications.
