Background and Objectives:
Circulating endothelial progenitor cells (EPCs) participate in vascular repair and predict cardiovascular outcomes. The aim of this study was to investigate the correlation between EPCs and abdominal aortic aneurysms (AAAs).
Methods:
and Results: Patients (age 67±9.41 years) suffering from AAAs (aortic diameters 58.09±11.24 mm) were prospectively enrolled in this study. All patients received endovascular aneurysm repair (EVAR). Blood samples were taken preoperatively and 14 days after surgery from patients with aortic aneurysms. Samples were also obtained from age-matched control subjects. Circulating EPCs were defined as those cells that were double positive for CD34 and CD309. Rat models of AAA formation were generated by the peri-adventitial elastase application of either saline solution (control; n=10), or porcine pancreatic elastase (PPE; n=14). The aortas were analyzed using an ultrasonic video system and immunohistochemistry. The levels of CD34+/CD309+ cells in the peripheral blood mononuclear cell populations were measured by flow cytometry. The baseline numbers of circulating EPCs (CD34+/CD309+) in the peripheral blood were significantly smaller in AAA patients compared with control subjects. The number of EPCs doubled by the 14th day after EVAR. A total of 78.57% of rats in the PPE group (11/14) formed AAAs (dilation ratio >150%). The numbers of EPCs from defined AAA rats were significantly decreased compared with the control group.
Conclusions
EPC levels may be useful for monitoring abdominal aorta aneurysms and rise after EVAR in patients with aortic aneurysms, and might contribute to the rapid endothelialization of vessels.

ObjectiveTo compare the effectiveness and mechanism of Xiangzhu Fanggan Formula (香术防感方) by sniffing and nasal drops for preventing influenza A H1N1flu. MethodsFifty-six BALB/c mice were randomly divided into normal group, model group, zanamivir group, high-concentration sachet group, low-concentration sachet group, high-concentration nasal drops group, and low-concentration nasal drops group, with 8 mice in each group. In the low- and high-concentration sachet groups, 15 g and 30 g of Xiangzhu Fanggan Formula sachet were used for sniffing for 24 h per day; while in the low- and high-concentration nasal drops groups, nasal drops of Xiangzhu Fanggan Formula were given at a concentration of 0.11 and 0.22 g/ml, 20 μl each time, twice a day; in the zanamivir group, zanamivir was given at a concentration of 1.025 mg/ml of 20 μl each time, twice a day; in the normal group and the model group, nasal drops of normal saline were given at 20 μl each time, twice a day. Each group was given prophylactic intervention for 5 days. On day 5, 1 h after the administration of the drug, the mice in all groups except the normal group received 35 μl of 50 LD50 A/PR/8/34/H1N1 viral solution as nasal drops to prepare influenza A H1N1 model mice. The body mass of the mice was recorded and the rate of change of body mass was calculated daily from day 5 to day 9 of the experiment, and the general status was observed. The mice were sampled on day 9, and the lung index and the inhibition rate of lung index were calculated; HE staining was used to detect pathological changes in lung tissues and to score lung tissue lesions; RT-qPCR was used to detect viral load in lung tissues; and ELISA was used to detect secretory immunoglobulin A (sIgA) and serum tumour necrosis factor α (TNF-α) and interleukin 2 (IL-2), interleukin 6 (IL-6), and interferon γ (IFN-γ) in the lavage fluid of the upper respiratory tract. ResultsOn days 7, 8 and 9 of the experiment, the rate of change in body mass of mice in the model group significantly lower than that in the normal group at the same time points (P<0.05 or P<0.01). On days 8 and 9 of the experiment, the rate of change in body mass of mice in the zanamivir group and the high-concentration nasal drops group increased when compared with the model group (P<0.05 or P<0.01). Compared with the normal group, mice in the model group had significantly higher lung index, lung tissue lesion score, lung tissue viral load, significantly higher serum TNF-α, IL-6, IL-2, IFN-γ levels, and significantly lower sIgA levels in the upper respiratory lavage fluid (P<0.01). Compared with the model group, the lung index and lung tissue viral load reduced, serum IFN-γ, TNF-α, IL-2, IL-6 levels reduced, and sIgA levels increased in the zanamivir group and the high-concentration nosal drops group (P<0.05 or P<0.01); except for low-concentration sachet group, lung tissue lesion scores of the drug intervention groups reduced compared with those of the model group (P<0.01). Compared with the zanamivir group, the lung index increased in the low-concentration sachet group and the low- and high-concentration nasal drops groups, and the serum TNF-α and IL-2 levels increased in all Xiangzhu Fanggan Formula intervention groups (P<0.05 or P<0.01). Compared with high-concentration nasal drops group, serum TNF-α and IFN-γ levels elevated in the high-concentration increased group, and lung tissue viral load elevated in the low-concentration nasal drops group (P<0.05 or P<0.01). The lung index inhibition rate was 80.84% in the zanamivir group, 41.61% and 17.90% in the high- and low-concentration sachet groups, and 35.40% and 25.40% in the high- and low-concentration nasal drops groups, respectively. HE staining showed that the lung tissues of the model group showed thickening of alveolar septa, alveolar collapse, and infiltration of inflammatory cells; whereas, in each drug intervention group, the inflammation of the lung tissues of the mice and the damage reduced, and the most obvious improvement was in the zanamivir group and the high-concentration nasal drops group. ConclusionXiangzhu Fanggan Formula by sniffing and nasal drops could both prevent influenza A H1N1 virus infection, with antiviral and anti-inflammatory effects, also could improve the pathological damage of lung tissue, and improve the immunity of respiratory mucosa. The nasal drops may be better than sachets in inhibiting inflammatory response, especially the high-concentration nasal drops showed more effective.

Over the past 50 years, the focus of acoustic neuroma surgery has shifted from low mortality and tumor resection to retention of neurological function. Hearing preservation is another point in addition to facial nerve function preservation. Hearing preservation rates overall ranged from 2% to 93% in recent studies. Characteristics such as approach, pre-operative neurological function, tumor size, nerve of origin and fundal fluid of the internal auditory canal have been reported as possible influencing factors. This review provides a summary of recent studies and describes the prognostic factors that predict hearing preservation.

Objective:
To evaluate the application of combination use of microscope and endoscope in cerebral pontine angle (CPA) surgery.
Methods:
A total of 72 patients undergone lateral skull base surgeries via endoscope under microscopic control from January 2006 to January 2015 was reviewed respectively. The patients including 35 males and 37 females were composed of 22 cases of vestibular swannnomas, 45 cases of cranial neuropathy and 5 cases of CPA chelesteatoma. Twenty cases of vestibular swannnomas, 15 cases of cranial neuropathy and 2 cases of CPA chelesteatoma undergone the surgery via retrosigmoid approach, while other cases undergone the surgery via retrolabyrinthine approach. Surgical procedures were accomplished under the control of microscope and different angular endoscope with imaging fusion. The surgical results were evaluated according to subjective and objective criteria, and all patients were followed up for 15 years.
Results:
The symptoms was disappeared in the cranial neuropathy patients, without facial paralysis, complication of other nerves or hearing loss. Twenty-two patients with vestibular schwannomas got total tumor removal without facial palsy or neurological deficits; useful hearing was preserved in 16 of 22 patients (72.7%), and no tumor recurrence was found during 1-5 years follow-up. There was also no facial palsy or other complications in 5 cases of CPA chelesteatoma, which gained completely surgical removal; useful hearing was preserved in 3 of 5 cases of these patients and no recurrence was occurred during 1-1.5 years follow-up.
Conclusions
A combination use of endoscope and microscope could combine advantages and avoid disadvantages of two techniques. It can provide better exposure with minimal invasion in CPA surgery, and is especially applicable in surgery for cranial neuropathy, vestibular schwannoma and CPA cholesteatoma, which should be performed through retrosigmoid approach and retrolabyrinthine approach.
