Methods: To treat freckles and lentigo with Q-Switched Alexandrite laser in different wave length and energy. Wave length 755nm,energy density 5~10J/cm2,frequency:5~10Hz,spot diameter 2~3mm,Wave length 532nm,energy 5~10J/cm2,frequency: 5~10Hz,spot diameter 2~3mm.128 cases of freckle were treated 2 times,32 cases of lentigo were treated 1~3 times,the interval is 3 months.

采用Q开关755nm激光，能量密度为5~10J/cm2；频率5~10Hz；2~3mm光斑直径；Q开关532nm，能量密度2~4J/cm2；频率5~10Hz，2~3mm光斑直径激光对雀斑及雀斑样痣进行治疗，其中雀斑128例，经两次治疗，雀斑样痣32例经1~3次治疗，治疗间隔为3个月，结束治疗后随访24个月。

The pDCs frequency in liver infiltrating lymphocytes in severe CHB patients was significantly higher than those in healthy controls, which was further confirmed by in situ immunohistochemical staining. Though pDCs frequency of LILs was higher than those in PBMCs in severe CHB patients, however, the LILs generated less amounts of IFN-a compared with the PBMCs under the same stimulation of CpG ODN, suggesting pDCs was, at least in part, dysfunctioned in the liver of severe CHB patients.

2与健康人比较，慢性乙型肝炎病人外周血中pDCs和NK细胞频率明显下降，并且CpG ODN2216刺激PBMCs产生IFN-α的能力也显著降低；相关性分析表明，慢性乙肝病人pDCs频率与ALT呈明显负相关，但与血浆病毒载量无明显相关。

A simultaneous dual-wavelength continuous wave, quasi-cw or linearly polarized wave diode-end-pumped Nd:YAG laser operating at 1319nm and 1338nm is demonstrated. To the best of our knowledge, our experimental results achieve the highest level in the domestic domain. The simultaneous dual-wavelength laser provides an experimental basis for generating highly coherent THz wave radiation of 3.23THz by nonlinear optical difference frequency method.2. A diode-end-pumped Nd:YAG crystal, type-I critical phase matching LBO crystal intra-cavity frequency doubled, simultaneous multi-wavelength red laser at 659.5nm, 664nm and 669nm is firstly realized.
