By Fig. 3-A it is found that effect shown in TFDS and different parts is different.Malonaldehyde (MDA) is as measurement cell
Lipid peroxide index can indirectly reflect the degree of injury of cell by measuring intracellular level of lipid peroxidation.
In MDA index, the effect that the low middle high dose of TFDS is showed is preferable, compared with model group, tool extremely significant difference
(P<0.001);It can be found from table 1, the TFDS under low dosage has been able to significantly reduce the generation of MDA.And P1 and model group
It compares, there is notable difference (P in middle high dose<0.01).In tri- dosage of P2, the generation of intracellular MDA can be reduced,
Especially in high dose effect, compared with model group group, great significant difference (P<0.001).
By observing GSH index in Fig. 3-B and table 1, it is found that the TFDS of high dose is strong to the protective effect of COM damaging cells
(P<0.001), illustrate that certain ingredients in TFDS have facilitation to the generation of GSH, enhance body resists lipidization energy
Power.And two positions P1, P2 also can promote the generation of GSH.It takes temperature from containing for GSH is generated, the effect of P2 is better than P1.
The height of SOD vigor indirectly reflects the ability of body scavenging activated oxygen, also reflects the physiology shape of cell
State.Cell SOD index determining result in Fig. 3-C and table 1 obtains:After P2 regional administration, the vigor of SOD is significantly increased, especially
In middle high dose (P<0.001), effect is best.
TFDS and different parts influence LDH leakage rate in COM damage HK-2 cell
As shown in Fig. 3 and table 1, model group is compared to the blank group compared with the cell LDH slip of model group obviously rises (P<
0.001), leakage rate reaches 40% or more.Compared with model group, the LDH slip of three administration groups is substantially reduced, and is had aobvious
Write sex differernce (P<0.001), wherein P2 is better than TFDS, P1 of same concentrations to the reduction effect of LDH slip under low dosage

TFDS and different parts influence the intracellular ROS of COM damage HK-2
The effect of HK-2 cell is damaged further to inquire into TFDS and different parts ingredient to COM, experiment uses active oxygen
Measurement further probe into active oxygen upon administration COM damage HK-2 cell model in variation.Experiment uses fluorescence probe
DCFH-DA is measured intracellular ROS active o content.Fig. 4 shows the HK-2 that TFDS and different parts damage COM
Cell ROS influences.
Fig. 4 is as the result is shown:Compared with normal cell, the active o content in model cell is much higher than blank group, reaches
3.40 times or so, there is significant statistical significance (P<0.001) after, illustrating COM modeling, lead to cell oxidative damage, cause
The a large amount of generations and accumulation of reactive oxygen species.When giving three groups of drugs and being intervened, TFDS and different parts ingredient energy
It is horizontal effectively to lower cell ROS.Wherein, P2-L (50 μ g/mL) group is compared with model group, and indifference is anisotropic, but P1-M (100 μ g/
ML), the active o content of P1-H (200 μ g/mL) reaches:2.6 times, 1.9 times are lowered respectively compared with model group:0.8
Again, 1.5 times;P2-L (50 μ g/mL), P2-M (100 μ g/mL), P2-H (200 μ g/mL) active o content reach:3.3 times,
It is horizontal to have lowered intracellular ROS respectively compared with model group for 2.5 times, 1.6 times:0.1 times, 0.9 times, 1.8 times;TFDS-L
(50 μ g/mL), TFDS-M (100 μ g/mL), TFDS-H (200 μ g/mL) active o content be:2.7 times, 1.6 times, 1.1 times;
Respectively compared with model group, it is horizontal that intracellular ROS has been lowered respectively:0.7 times, 1.8 times, 2.3 times.
As a result illustrate that TFDS can significantly reduce active oxygen generation, protection COM sticks cellular damage caused by HK-2 and drawn
The oxidative damage risen.Compared with model group, TFDS just has significant difference (P since low concentration<0.05), middle high dose
Under, great significant difference (P<0.001);The effect of position P1, P2 at low concentration (50 μ g/mL) to active oxygen, with model
Group compares no significant difference, when reaching high dose, has significant difference (P<0.001), great significant difference.Therefore,
In the reduction effect for the HK-2 reactive oxygen species that TFDS and different parts stick COM, the effect of TFDS is best.And P1 with
P2 compares, and under middle high dose, P2 is better than P1 to the adjustment effect of active oxygen.
TFDS and different parts, which stick HK-2 cell MMP to COM, to be influenced
Experiment uses cell membrane inner mitochondria film current potential (MMP), and the change of cell membrane potential is detected by JC-1 fluorescence probe
Change, detecting TFDS and different parts as Testing index influences COM damage HK-2 mitochondrial membrane potential in anoxic.
Experimental result is as shown in figure 5, compared with normal cell group, after giving COM pharmaceutical intervention, in model group cell
Red green fluorescence ratio significantly reduce to 0.68 (P<0.001), illustrate that COM can significantly reduce mitochondrial membrane potential in anoxic.When
When TFDS and different parts intervene the HK-2 cell model that COM sticks, the mitochondrial membrane potential of cell is had occurred significantly
Variation.Three concentration in TFDS can significantly raise the red green fluorescence ratio of mitochondrial membrane potential:1.06(P<0.05),1.59
(P<0.01),2.52(P<0.001);But the red green fluorescence ratio of the mitochondrial membrane potential of administration group P2-H is up to 2.65 (P<
0.001), the high dose of the slightly excellent general flavone of effect, can conspicuousness (P<0.001) the red green fluorescence ratio of regulation mitochondrial membrane potential
It is horizontal.
The bis- dye Apoptosis by Flow Cytometries of AnnexinV-FITC/PI influence
Fig. 6, which shows TFDS and different parts, causes HK-2 Apoptosis to influence COM.
It can be found from Fig. 6 cell apoptosis assay, the Apoptosis of model group reaches 14.0%, and normal cell group apoptosis reaches
1.8%, model group Apoptosis conspicuousness increases (P<0.001).TFDS and each elution regional administration can effectively inhibit cell
The low middle high dose of apoptosis, TFDS reduces the apoptosis of cell to 8.4% (P<0.05), 3.7% (P<0.01), 3.7% (P<
0.01);And the low middle high dose of P1 inhibits the apoptosis rate of cell to respectively reach:7.0% (P<0.01), 5.9% (P<0.01),
2.8% (P<0.001);The P2 of low middle high dose makes apoptosis rate reduce by 3.5%, 3.1%, 2.4%, has compared with model group
There is significant difference (P<0.001).By Fig. 5 it is evident that TFDS and different parts administration inhibit Apoptosis, and have
Concentration dependent.Wherein, the apoptosis rate of P2 inhibits apoptotic effect better than TFDS under same dose, is secondly TFDS.
On Western Blot method detection TFDS and the HK-2 cell membrane that sticks to COM of opposed polarity position occludin with
ZO-1 protein expression influences
Fig. 7 shows occludin and ZO-1 protein expression on the HK-2 cell membrane that TFDS and different parts stick COM
It influences.A represents occludin protein expression;B represents ZO-1 protein expression.
As shown in fig. 7, occludin and ZO-1 albumen table compared with normal cell, in calcium oxalate COM model group cell
It is lowered up to significant, occludin albumen is lowered to 0.46 (P<0.001), ZO-1 albumen is lowered to 0.45 (P<0.001).?
In occludin Protein Assav, administration group TFDS concentration is respectively 50,200 μ g/mL, compared with model group, respectively on be transferred to:
0.65(P<0.05), 1.21 (P<0.01);P1 concentration is respectively 50,200 μ g/mL, compared with model group, respectively on be transferred to:
0.79(P<0.001)0.90(P<0.05);And in P2, respectively on be transferred to:0.79(P<0.05), 1.23 (P<0.01).In ZO-
In 1 Protein Assav, administration group TFDS concentration be 50,200 μ g/mL, compared with model group, respectively on be transferred to:0.97(P<
0.05), 1.45 (P<0.001);P1 concentration be 50,200 μ g/mL, compared with model group, respectively on be transferred to:1.02(P<
0.001), 1.11 (P<0.001);And in P2, respectively on be transferred to:1.29(P<0.001), 1.67 (P<0.001).
Therefore, in the experiment of kidney stone cell model, COM causes occludin and ZO-1 albumen on cell membrane to lower,
By the processing at TFDS and different elution positions, discovery occludin and ZO-1 albumen have up-regulation trend, as a result illustrate TFDS
And different elution positions have the function of promoting occludin and ZO-1 protein upregulation, TFDS treatment kidney stone may be by adjusting
Section occludin and ZO-1 reach curative effect.And in TFDS and different elution positions, compared with other two groups.It was found that P2 is in height
Dosage (200 μ g/mL) is most strong to the adjustment effect of occludin albumen, and in ZO-1 adjustment effect, P2 pairs of low high dose
The up-regulation effect of occludin and ZO-1 albumen is strong.
By above-mentioned it can be proved that oxidative damage, thorn occur for cell when HK-2 cell membrane surface is sticked by COM
The generation of activity oxygen leads to a series of generation of Petoxidation products, the content decline of antioxidant.It can be sent out from experiment
It is existing.85% elution position (P2) of TFDS can reduce COM and stick active o content caused by HK-2 cell, lower ability
By force, and TFDS also shows stronger downward effect, damage of the active oxygen to cell can be reduced, protect cell membrane.And TFDS
25% elution position (P1) can also lower the content of active oxygen to a certain extent, but lower ability and be weaker than the above two.Wide money
Careless general flavone ODS column 25% elutes position or/and Desmodium styracifolium general flavone ODS column 85% elutes position and has protection HK-2 cell
Effect.The mitochondrial membrane potential damage that COM stimulation HK-2 cell generates can be effectively reduced, there is the function of protection mitochondria
Energy;Occludin is raised, the protein content expression of ZO-1 regulates and controls barrier function and the osmotic pressure effect of TJ, subtracts and hurt COM to cell membrane
Damage.Reduce damage and the apoptosis of cell.
