We review our investigations devoted to the analysis of the resonances Zc(3900) , Zc(4430) , Zc(4100) , X(4140) , X(4274) , a1(1420) , Y (4660) , X(2100) , X(2239) , and Y (2175) discovered in various processes by Belle, BaBar, BESIII, D0, CDF, CMS, LHCb and COMPASS collaborations. These resonances are considered as serious candidates to four-quark (tetraquark) exotic mesons. We treat all of them as diquark-antidiquark states with relevant spin-parities, find their masses and couplings, as well as explore their dominant strong decay channels. Calculations are performed in the context of the QCD sum rule method. Thus, the spectroscopic parameters of the tetraquarks are evaluated using the two-point sum rules. For computations of the strong couplings GT M 1 M 2 , corresponding to the vertices T M1M2 and necessary to find the partial widths of the strong decays T → M1M2 , we employ either the three-point or full/approximate versions of the QCD light-cone sum rules methods. Obtained results are compared with available experimental data, and with predictions of other theoretical studies.

“…Recently, most of the theoretical studied on the exotic states are relied on effective theories and models, for example the studies of mass spectrum within the simple quark model [27], Iachello mass formula [28] and QCD sum rules [29]. However, the light quark flavor SU (3) symmetry is also a useful tool to analyze the decays of hadrons, which has been successfully applied for the ordinary meson or baryon case [30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][45][46][47][48][49].…”

We perform a SU(3) analysis for both semi-leptonic and non-leptonic heavy meson weak decays into a pseudoscalar meson and a fully-light tetraquark in 10 or 27 representation.A reduction of the SU(3) representation tensor for the fully-light tetraquarks is produced and all the flavor components for each representation tensor are listed. The decay channels we analysis include B/D → U/T P lν, B/D → U/T P and B c → U/T P/D, with U/T represents a fully-light tetraquark in 10 or 27 representation and P is a pseudoscalar meson.Finally, among these results we list all the golden decay channels which are expected to have more possibilities to be observed in experiments.

Chronic hyperglycemic damage is a major problem that undermines diabetic wound healing. By combining treatment and diagnosis together, blood glucose concentration can be monitored real-time through medical imaging devices and precise interventions can be carried out at the right time to promote diabetic wound repair. In this study, an injectable self-healing hyaluronic acid hydrogel is constructed using Schiff base reaction, and nanoenzymes (GOx-MnO 2 ) synthesized by condensation reaction, along with vascular endothelial growth factor (VEGF)-nanobubbles produced by double emulsification method, are loaded into the hydrogel, thus constructing an innovative diagnostic and therapeutic hydrogel system (US@GOx@VEGF hydrogel, UGV hydrogel). While monitoring glucose concentration in real-time, the system delivers VEGF through ultrasound in a precise and noninvasive way to deplete glucose. The UGV hydrogel integrates both processes of diagnosis and treatment, effectively releases VEGF through blasts triggered by ultrasound. Apart from this, this new trauma patch is capable of monitoring Mn 2+ values ranging from 0.5 m to 7.8 × 10 −3 m and glucose levels from 100 × 10 −3 to 3 × 10 −3 m, through magnetic resonance imaging. In summary, the hydrogel realizes real-time monitoring of glucose level, maintains glucose homeostasis through noninvasive intervention, and rapidly promotes the repair of diabetic skin defects, opening up a new path for chronic wound management.
