The coexistence of myelolipoma within adrenal cortical adenoma is extremely rare, for both tumors present usually as separate entities. There are only 16 such cases reported worldwide. To the best of our knowledge, the case we reported here is the first one of myxoid adrenal cortical adenoma associated with myelolipoma reported. A 32-year-old Chinese woman with 4-year history of hypertension was presented in our study. Computed tomography (CT) of the abdomen showed a large heterogeneously-enhancing mass (4.5 cm in diameter) in the left suprarenal region. Clinical history and laboratory results suggest a metabolic disorder as Conn's syndrome. The patient underwent a left adrenalectomy, and a histopathological study confirmed the mass to be a myxoid adrenal cortical adenoma containing myelolipoma. The patient was postoperatively well and discharged uneventfully. In the present case report, we also discuss the etiology of simultaneous myelolipoma and adrenal adenoma associated with Conn's syndrome, and the methods of the diagnosis and differential diagnosis.

The removal of organic pollutants using green environmental photocatalytic degradation techniques urgently need high-performance catalysts. In this work, a facile one-step hydrothermal technique has been successfully applied to synthesize a Nb2O5 photocatalyst with uniform micro-flower structure for the degradation of methyl orange (MO) under UV irradiation. These nanocatalysts are characterized by transmission and scanning electron microscopies (TEM and SEM), X-ray diffraction (XRD), Brunauer–Emmett–Teller (BET) method, and UV-Vis diffuse reflectance spectroscopy (DRS). It is found that the prepared Nb2O5 micro-flowers presents a good crystal phases and consist of 3D hierarchical nanosheets with 400–500 nm in diameter. The surface area is as large as 48.6 m2 g−1. Importantly, the Nb2O5 micro-flowers exhibit superior catalytic activity up to 99.9% for the photodegradation of MO within 20 mins, which is about 60-fold and 4-fold larger than that of without catalysts (W/O) and commercial TiO2 (P25) sample, respectively. This excellent performance may be attributed to 3D porous structure with abundant catalytic active sites.

Service intangibility and interactive means service product performance standards vary from person to person, so the service innovation must be is to take the "prior" in a controlled manner. Managers should cultivate service climate by training system, internal competition mechanism, authorization system, information channels and so on. A large number of theoretical researches and management practice of enterprises have proved that service climate can enhance staffs' skills and emotion, establish the consciousness of service and stimulate organizational citizenship behavior, so as to improve customer perceived service quality and their satisfaction. Different from the manufacturing technology, the service product is provided instantly, the staffs' performance in the "truth moment" directly determines the customer's satisfaction. So it is difficult to monitor and evaluate the service in "truth moment". Service atmosphere can replace the monitoring of the management for staff's service behavior. Strong service climate of enterprises can provide employees with the freedom and resource to encourage staffs to implement service innovation. For employees, the service enterprise service climate is more strong, the more likely to inspire a sense of service oriented and to seek a better solution for customers' problems. In addition, service products need customers to participate in the service, the service climate of the enterprise will have an impact on the customer's perception and regulate the customer's mind, then affect the evaluation of the service. Therefore, service companies must create service climate, promote service innovation and corporate brand building by the service climate.
