Objective: To review the experience of the management of carotid body tumours in a major vascular centre in mainland China.
Patients and methods: This was a retrospective review of 52 cases of ...carotid body tumour. There were 24 male and 28 female patients with an age range of 18–67 years; and 23 right‐sided, 24 left‐sided and five bilateral lesions. The modality of preoperative imaging was as follows: duplex scan and computed tomography in 40 cases, magnetic resonance imaging in 10 cases, carotid artery angiogram in 32 cases with selective embolization of the feeding vessel in 19. Operative treatment was carried out for 55 lesions and was summarized as follows: simple tumour excision for 44 lesions and en bloc tumour excision together with carotid bifurcation for 11 lesions; ICA reconstruction with interposition graft in three cases; and external to ICA anastomosis in two cases.
Results: There were no operative mortalities. Postoperative complications included two ischaemic strokes, one case of vagus nerve damage and one case of hypoglossal nerve damage.
Conclusion: Carotid body tumour is a rare neoplasm. Its special anatomical position imposes great difficulty during surgery. Adequate preoperative preparation and embolization of feeding arteries could reduce operative blood loss, improve tumour excision and preserve the ICA flow.

Private-placing fund in the past decade has soon become a booming phenomenon attracting affluent investors who poured money into it for seeking various investment opportunities on ...one hand and for bypassing governmental restriction on the other. How astonishing is to find that there is sparse literature discussing the investment behavior of private-placing fund managers in the sense of whether they are capable of making profits for their clients? Moreover, what might be the source of their capability if they are able to beat the benchmark?
Referring to the characteristics-based model proposed by Daniel et al. (1997) and Wermers (2000), we investigate the investment behavior and performance measure of a certain private-placing fund manager. The capability of fund managers is decomposed into characteristics selectivity and characteristics timing. Two set of benchmarks are constructed as follows: matching by industry and equity size and matching by equity size only. The results show that the ca
