Treatment of 198 Cases of Thyroid Nodules with Sanying Capsule Combined with Xiaoying Patch

[Objectives]To observe the clinical efficacy of Sanying capsule combined with Xiaoying Patch in treating thyroid nodule(TN).[Methods]Two groups were treated similarly,with 200 cases in the control group undergoing basic treatment for 12 weeks and 198 cases in the observation group receiving Sanying capsule combined with Xiaoying patches for the same duration.The clinical symptoms,number of nodules,diameter of the largest nodule,and maximum reduction of nodules were observed before and after treatment.A control analysis was performed,and the underlying mechanisms were explored.[Results]The primary symptoms of the observation group exhibited a more favorable improvement than those of the control group.Additionally,the number of nodules decreased,the diameter of the largest nodule decreased,and the maximum reduction of nodules decreased in both groups following treatment.However,the observation group demonstrated a more pronounced improvement than the control group(P<0.05).[Conclusions]The combination of Sanying capsule and Xiaoying patch has been demonstrated to be an effective treatment for TN,with a high degree of reliability in terms of safety.

Phase-field simulation of early-stage kinetics evolution ofγ’phase in medium supersaturation Co-Al-W alloy

The early precipitation ofγ’-Co3(Al,W)phase affects the spatial distribution and kinetic evolution of precipitates for the morphology transmission effect,but the nucleation and concomitant growth are not studied still by aging experiments due to the expeditious precipitation ofγ’phase in Co-Al-W alloy.By using the phase-field simulation with sublattice free energy,the early-stage kinetics evolution ofγ’-Co3(Al,W)phase in a medium supersaturation Co-9 Al-8 W(at.%)alloy aged from 1023 K to 1173 K is investigated.The influences of aging temperature on the evolution of morphology and composition ofγ’phase,and the kinetics of nucleation and growth to coarsening are clarified.It is found that the rates of composition evolution of W inγphase are two or three times that ofγ’phase,and the W compositions inγandγ’phases show a linear relationship with time t–1/3,which means that the coarsening takes place earlier at high temperature.In addition,the equilibrium partitioning ratios indicate Al and W partition into theγ’phase and the ratios decrease with elevated temperature.The compositional variations across theγ/γ’phase interfaces suggest that low aging temperature makes the stoichiometric ratio closer to 3:1.Moreover,the precipitation evolutions from early nucleation to growth and coarsening in Co-Al-W alloy are distinguished,and the rate constants of square and cube of average particles radius increase with temperature.In later growth stage,the relationship of the square of average particles radius and time is obeyed,while the steady-state coarsening stage follows the cube law.The time exponents of particles number density at the coarsening stage are close to–1 of Kuehmann-Voorhees(KV)theory.The study demonstrates that the early-stage evolution ofγ’phase which is undiscovered in the experiment can be captured by the phase-field simulation,and the resultant kinetics laws agree well with the experimental and theoretical results.

Protein phosphatase magnesium-dependent 1δ is a novel tumor marker and target in hepatocellular carcinoma

Hepatocellular carcinoma （HCC） is a lethal liver malignancy worldwide. In this study, we reported that protein phosphatase magnesium-dependent 16 （PPM1D） was highly expressed in the majority of HCC cases （approximately 59%） and significantly associated with high serum a-fetoprotein （AFP） level （P = 0.044）. Kaplan- Meier and Cox regression data indicated that PPM1D overexpression was an independent predictor of HCC- specific overall survival （HR, 2.799; 95% CI, 1.346-5.818, P = 0.006）. Overexpressing PPM1D promoted cell viability and invasion, whereas RNA interference-mediated knockdown of PPM1D inhibited proliferation, invasion, and migration of cultured HCC cells. In addition, PPM1D suppression by small interfering RNA decreased the tumorigenicity of HCC cells in vivo. Overall, results suggest that PPM1D is a potential prognostic marker and therapeutic target for HCC.
