We systematically investigate the mass spectra of$\{Q\bar{s}\}\{\bar{Q}^{(')}s\}$ molecular states in the framework of QCD sumrules. The interpolating currents representing the molecular states areproposed. Technically, contributions of the operators up to dimension six areincluded in operator product expansion (OPE). The masses for molecular stateswith various $\{Q\bar{s}\}\{\bar{Q}^{(')}s\}$ configurations are presented. Theresult $4.36\pm0.08 GeV$ for the $D_{s}^{*}\bar{D}_{s0}^{*}$ molecular state isconsistent with the mass $4350^{+4.6}_{-5.1}\pm0.7 MeV$ of the newly observed$X(4350)$, which could support $X(4350)$ interpreted as a$D_{s}^{*}\bar{D}_{s0}^{*}$ molecular state.
