Objective To observe the anatomy status of the anterior clinoid process (ACP)and the anterior clinoid segment of in-ternal carotid artery (ICA)respectively by multisliced computed tomography (MSCT),and to provide useful imaging information for ACP removal surgery.Methods A total of 100 patients (200 sides)had volume rendering reconstruction of skull.Cranium was removed along cranio-orbital bone in simulation.Then the anatomical structures of the ACP and its surrounding were observed in cephalad direction.The total length,medium length,basic width,medium width of the ACP and the sagittal view curve length of anterior clinoid segment of the ICA from both sides were measured.Results Total length of left ACP was (9.82±2.48)mm,basal width was (9.47±1.88)mm,medium length was (5.03±1.55)mm,medium width was (6.1 9 ±1.75)mm;for right side total length was (10.41±2.1 6)mm,basal width was (9.66 ±2.21)mm,medium length was (5.86 ±2.48)mm,medium width was (6.66±1.5 1)mm.Left anterior clinoid segment of ICA curve length was (6.74±2.25)mm;right was (8.54±3.00)mm.Paired sample t test showed no significant difference in total length,basal width and medium width of ACP in both sides (P >0.05);while the difference in medium length and curve length of the anterior clinoid segment of ICA were statistically significant respectively (P <0.05).Conclusion MSCT can clearly display the vivisection and variation status of the ACP and the anterior clinoid segment of the ICA and can provide useful imaging information for removal of ACP in operation.

Purpose To study the exposure extent of internal carotid artery siphon (ICAS) before and after removing anterior clinoid process (ACP) using multislice spiral CT (MSCT) simulation, and to improve the tumor resection rate and ensure the operation effect. Materials and Methods MSCT three-dimensional images reconstruction simulating supraorbital keyhole approach of 100 patients (200 sides) were observed, the distance between the crotch of anterior cerebral artery and middle cerebral artery and ICAS before and after removing ACP (exposure extent) was measured. Results In 100 patients (200 sides ACP), the exposure extent before and after removing ACP were (14.3±3.9) mm and (30.5±4.2) mm, respectively on the left side with statistical difference (t=45.278, P<0.001), and were (15.9±3.8) mm and (31.8±3.9) mm, respectively on the right side with statistical difference (t=40.513, P<0.001). The exposure extent increased (16.3±3.6) mm and (15.8±3.9) mm, respectively on the left and right side with no statistical difference (t=0.251, P>0.05). Conclusion MSCT simulating supraorbital keyhole approach in removing ACP can effectively increase the exposure length of ICA, and enlarge the exposure extent of sella region, thus provide reliable imaging information for removing tumor and selecting surgical project in this region.

OBJECTIVETo observe preventive and therapeutic effect of Yifei Jianpi Recipe (YJR) on chronic obstructive pulmonary disease (COPD) model rats and to explore its mechanism from the way of airway inflammation and airway mucus hypersecretion.

METHODSThe COPD rat model was established by using cigarette smoking combined with intratracheal injection of lipopolysaccharide (LPS). Male SD rats were randomly divided into the blank control group (control group), the model group, the YJR group, 6 in each group. Forced vital capacity (FVC), forced expiratory volume in 0. 1 second (FEV0. 1), FEVO. 1/FVC, peak expiratory flow (PEF) was tested by lung function device. Pathological changes of bronchi and lung tissues were observed by HE staining. Airway Goblet cells were observed using AB-PAS staining. Contents of IL-8, IL-17, and TNF-α in bronchoalveolar lavage fluid (BALF) were measured by enzyme-linked immunosorbent assay (ELISA). Protein expressions of intercellular cell adhesion molecule-1 (ICAM-1), nuclear factor KB (NF-KB), mucin 5AC (Muc5AC), and Toll-like receptor 4 (TLR4) in rat airway were detected by immunohistochemical assay. mRNA expressions of TLR4 and Muc5AC in bronchi and lung tissues were detected by real-time quantitative PCR (RT qPCR).

RESULTSChanges of bronchi and lung tissues in the model group rats were consistent with typical pathological manifestations of COPD. Compared with the model group, the degree of lung injury was significantly alleviated in the YJR group. Compared with the control group, FVC, FEV0. 1, FEVO. I/FVC, and PEF were decreased (P <0. 01), contents of IL-8, IL-17, and TNF-α in BALF were significantly increased (P <0. 01), protein expressions of ICAM-1, NF-KB, Muc5AC, and TLR4, mRNA expression levels of Muc5AC and TLR4 in bronchi and lung tissues were also significantly increased in the model group (P <0. 01). Compared with the model group, FVC, FEV0. 1, FEV0. 1/FVC, and PEF were significantly increased in the YJR group (P <0. 01, P <0. 05), but the rest indices were significantly lowered (P <0. 01, P <0. 05).

CONCLUSIONYJR could decrease contents of IL-8, IL-17, and TNF-α in BALF of COPD model rats, inhibit protein expression levels of ICAM-1, NF-κB, Muc5AC, and TLR4.in airway and lung tissues, thus playing preventive and therapeutic roles by reducing airway inflammation and airway mucus hypersecretion.

Objective To investigate the suppression effects of Tripotolide (TL) on the pancreatic cancer xenograft models and angiogenesis. Methods The growth suppression effect of TL on SW1990 was determined using cell count kit (CCK-8), apoptotic cells induced by TL were examined by morphology and terminal deoxynucleotidyl transferase-mediated nick end labeling (TUNEL) assay. The inhibitory effects of TL on the growth of tumor xenografts and tumor microvascular density (MVD) were investigated. ResultsTL inhibited the growth and proliferation of SW1990 cells in a concentration-dependent and time-dependent manner. The inhibition ratios of cells treated at 160 mg/ml TL for 24 h was 50. 6%, the apoptotic rate increased from 9.6% in the control group to 45.1% (P <0.01 ). The inhibition rate of cancer xenograft growth was 89.9% when TL was intratumorally injected at the dose of 0.5 mg/kg. The expression of VEGF in tumor tissue decreased while MVD also decreased from 36.25±8.64 to 9.87±3.34 (P <0.01 ). ConclusionsTL induced prominent growth inhibition and apoptosis in human pancreatic cancer cell lines. TL.can attenuate the growth of pancreatic caner xenografts through its effect on antiangiogenesis.

Objective to investigate the feasibility and outcomes of different surgical treatments for adrenal metastasis after previous radical ne-phrectomy for patients with renal cell carcinoma. Methods A total of 18 adrenal solitary metastasis of renal cell carcinoma were identified from da-tabase of two institutions between 2003 and 2013. Clinical and pathologic data were collected and analyzed. Results Of 9 patients who had ipsilater-al metastasis of the renal tumor,the estimated blood loss were obviously fewer in the transperitoneal LA group. Of 9 cases who had contralateral me-tastasis of the renal tumor,the fasting time[(1.4±0.8)h vs(4.0±1.4)h,P = 0.036]and length of hospital stay[(4.5±1.2)d vs(7.0±4.5)d,P =0.041]were obviously fewer in the retroperitoneal LA group. the averages of the fasting time and length of hospital stay in the retroperitoneal LA group were obviously smaller than in the transperitoneal LA group. Conclusion LA for treatment of renal cell carcinoma metastasis is technically feasible in selected patients. transperitoneal and retroperitoneal LA can be respectively recommended as an appropriate approach for isolated adrenal metastases of ipsilateral and contralateral renal cell carcinoma after nephrectomy.
