Objective To study transcerebellomedullary fissure approach to the fourth ventricle and the lateral brainstem without splitting vermis and depict its adjacent structure, and provide clinicians with anatomical information.Methods Five cadaveric heads fixed with formaldehyde and perfused with color latex in their arteries and veins were dissected with microsurgical anatomical skills. The composition of cerebellomedullary fissure and the distribution of the tela choroida, the inferior medullary velum and the posterior inferior cerebellar artery, and study anatomic base of this approach.Results Cerebellomedullary fissure is a natural anatomical gap which is located between the cerebellar tonsil, biventral lobule and medulla oblongata. The tela choroida and inferior medullary velum do not contain nerve tissue, and thus can be dissected to expose the fourth ventricle. The tonsil- medulla segment and telovelotonsillar segment of the posterior inferior cerebellar artery are the most important blood vessels of the cerebellomedullary fissure approach.Conclusions The transcerebellomedullary fissure approach can reach the fourth ventricle and dorsal brain stem through normal anatomic spaces without splitting the vermis, thus reducing the post-operative complications.

Objective:To investigate the application value of multi-slice spiral CT angiography in the clinical diagnosis of aortic dissection.Methods:The clinical data of 78 patients with aortic dissection diagnosed by digital subtraction angiography and treated between January 2015 and December 2019 in Putuo District People's Hospital of Zhoushan and Zhoushan Hospital were retrospectively analyzed. All patients underwent multi-slice spiral CT angiography and digital subtraction angiography. The type of aortic dissection, the number of aortic lacunas, the distance between the lacuna and the left subclavian artery, the involved branches, the percentage of artery wall calcification, and arterial dissection thrombosis determined by multi-slice spiral CT angiography and digital subtraction angiography were compared.Results:All 78 patients were diagnosed with aortic dissection by digital subtraction angiography, and 75 (96.2%) were diagnosed with aortic dissection by multi-slice spiral CT angiography. The same type of aortic dissection was detected by multi-slice spiral CT angiography and digital subtraction angiography, but three patients were misdiagnosed with pericarditis by multi-slice spiral CT angiography. There were no significant differences in the number of aortic lacunas and the distance between the lacuna and the left subclavian artery between the two methods ( t = 1.02, 0.57, both P > 0.05). The involved branches [61.3% (46/78),] the percentage of artery wall calcification [26.7% (20/78)], and the percentage of arterial dissection thrombosis [78.7% (59/78)] determined by multi-slice spiral CT angiography were significantly higher than 43.6% (34/75), 12.8% (10/75), and 62.8% (49/75) respectively determined by digital subtraction angiography ( χ2 = 4.83, 4.65, 4.62, all P < 0.05). Conclusion:Multi-slice spiral CT angiography exhibits a similar capacity to identify aortic dissection to digital subtraction angiography. It can accurately determine the number and location of aortic lacunas, display the calcification and thrombosis of vascular wall, and is minimally invasive and simply operated. Therefore, multi-slice spiral CT angiography is of high application value in the clinical diagnosis and preoperative evaluation of aortic dissection.

Objective To investigate the distribution and antibiotic resistance of clinical isolates in People’s Hospital of Qingyang during 2014 to provide evidence for rational antimicrobial therapy.Methods Bacterial strains were isolated and identified by routine methods and tested by disk diffusion method and E-test for antimicrobial susceptibility. The data were analyzed according to CLSI breakpoints using WHONET 5.6 software.Results Of the 2 121 nonduplicate strains isolated from January through December 2014, 1 565 (73.8%) were gram-negative and 556 (26.2%) were gram-positive strains. The top ifve pathogens wereE. coli, K. pneumoniae, A. baumannii, S. aureusand P. aeruginosa. The prevalence of methicillin-resistantStaphylococcus aureus (MRSA) and methicillin-resistant coagulase negativeStaphylococcus (MRCNS) was 44.6% and 15.4%, respectively.E. coli was the most common gram-negative bacterial species, whileS. aureus was the most common gram-positive bacteria species. Gram-positive bacteria were still highly susceptible to vancomycin, and gram-negative bacteria (such as Enterobacteriaceae) were still highly susceptible to carbapenems.ConclusionsE. coli is the most prevalent pathogen isolated from inpatients in this hospital during 2014. The prevalence of ESBLs-producing strains is the highest inE. coli isolates. The pathogenic bacteria in this hospital showed increasing resistance to a variety of antibacterial agents. Surveillance of antibiotic resistance and effective control measures are necessary to control the growing antimicrobial resistance.

Objective To investigate the correlation of dynamic contrast-enhanced (DCE) MRI features with microvessel density (MVD) and vascular endothelial growth factor (VEGF) in non-small cell lung cancer(NSCLC).Methods Conventional MR imaging and dynamic contrast-enhanced scan in thirty-three patients with NSCLC confirmed by pathologyn were performed. MVD and VEGF were stained with immuno-histochemical technique in all cases. Some parameters of DCE MRI, including maximum slope(Smax) and time to peak(TTP) were put more analysis. The relationship between the results of DCE MRI (Smax and TTP) and that of immuno-histochemistry (MVD and VEGF) was analysed.Results The Smax of adeno carcinoma was higher than that of squamous cell carcinoma,but TTP was lower. The difference was obvious difference(t=3.22,P

Objective To explore the methods of thoracoscopic intrapleural perfusion hyperthermic chemotherapy(TIPHC)on diagnosing and treating malignant pleural effusion caused by lung cancer,as well as its effect.Methods From February 1999 to March 2006,seventy patients with malignant pleural effusion caused by lung cancer were randomly divided into therapeutic group(35 cases)and control group(35 cases).Pleural biopsy and TIPHC under general anesthesia with unilateral ventilation were performed in the therapeutic group,and intrapleural injection of cisplatin was administered in the control group after drainage of pleural effusion.The effect on malignant pleural effusion,the change for the concentration of carcino-embryonic antigen(CEA),cytokeratin-19 fragments(CYFRA21-1),neuron-specific enolase(NSE)and the side effect were compared before and after the treatment.Results The therapeutic group achieved total response rate of 100%,but only 54.3% in the control group,with significant difference(P

Objective To analyze and compare results of local lymph node assays (LLNA) between BALB/c and CBA mice.Methods 4 chemicals (2,4-dinitrochlorobenzene, eugenol, hexyl cinnamic aldehyde and isopropanol) and 3 cosmetics were applied to the dorsum of both ears of Balb/c and CBA mice for three consecutive days.BrdU solution was injected inter-peritoneally on day 5.On day 6, the bilateral draining auricular lymph nodes were excised and made into single cell suspension, the lymph cell proliferation was measured by BrdU ELISA kit.Results 2,4-dinitrochlorobenzene, eugenol, hexyl cinnamic aldehyde and NO.3 perm agent pretended positive for both strains, EC1.6 values of three chemicals were found to be 0.08% (very strong), 4.02% (moderate), 6.68% (moderate) and 0.07% (very strong), 6.08% ( moderate), 8.89% ( moderate) for BALB/c and CBA mice respectively.Isopropanol, NO.1 and NO.2 cosmetics pretended to be non-sensitizers with SI <1.6 for both strains.Conclusion This study showed that BALB/c mouse was essentially equal to CBA for LLNA: BrdU-ELISA, which suggested that BALB/c mouse was a good alternative for CBA used in chemicals and cosmetics allergenic evaluation.
