We show that when A is a separable C*-algebra,every countably generated Hilbert A-module is projective（with bounded module maps as morphisms）.We also study the approximate extensions of bounded module *** the case where A is a σ-unital simple C*-algebra with strict comparison,and every strictly positive lower semicontinuous affine function on quasitraces can be realized as the rank of an element in the Cuntz semigroup,we show that the Cuntz semigroup is equivalent to unitarily equivalent classes of countably generated Hilbert A-modules if and only if A has stable rank one.

BACKGROUND Central nervous system(CNS) metastases are a catastrophic complication of nonsmall cell lung cancer(NSCLC), including brain and leptomeningeal carcinomatosis, and are always accompanied by a poor prognosis. Despite the continuous development of existing treatments, the therapy of CNS metastases remains *** SUMMARY We report a patient who was definitively diagnosed with brain and leptomeningeal metastases from NSCLC with a targeted mutation in epidermal growth factor receptor(EGFR). A standard dosage of icotinib(125 mg three times daily) was implemented but ineffective. CNS lesions developed despite stable systemic control, so pulsatile icotinib(1125 mg every 3 d) was administered. This new strategy for administration has lasted 25 mo so far, and resulted in complete remission of neurological symptoms, almost vanished lesions, and longer survival with no notable side *** This is the first successful example of pulsatile icotinib for treating isolated CNS progression from EGFR mutation-positive NSCLC, providing a new alternative for the local treatment of CNS metastases.

A one-dimensional(1 D) coordination polymer, [Cd2(TFBPDC)2(ad)2(CH3 OH)2]n(1), based on the 3,3’,5,5’-tetrafluorobiphenyl-4,4’-dicarboxylate(TFBPDC2-) and adenine(ad) ligands, was synthesized. Compound 1 crystallizes in the triclinic system, space group P1 with a = 9.7067(3), b = 9.9501(3), c = 11.6903(4) ?, α = 93.036(3), β = 107.793(3), γ = 107.107(3)°, V = 1014.77(6) ?3, Z = 2, C40H26F8N10O10Cd2, Mr = 1183.51, Dc = 1.937 g/cm3, μ = 1.160 mm-1, F(000) = 584, the final R = 0.0284 and wR = 0.0635 for 3791 observed reflections with Ⅰ> 2s(I). In 1, a pair of adenine(ad) ligands bridge two octahedrally coordinated Cd(Ⅱ) atoms to form a dinuclear [Cd2(ad)2] unit, which is linked by TFBPDC2- to generate a 1 D double chain. The neighboring chains are connected by N-H×××O hydrogen bonds to give a two-dimensional(2 D) layer, which is further linked by the O-H×××N hydrogen bonds to give a three-dimensional(3 D) supramolecular framework. IR spectrum, thermogravimetric analysis, and powder X-ray diffraction of 1 were provided. Compound 1 shows luminescent emission.
