Objective To investigate effect of guanosine diphosphate (GDP) on the mitochondrial respiratory oxygen consumption and the mitochondrial membrane potential (MMP) of rat brain and explore the relationship of the change of uncoupling proteins (UCPS) activity with the oxygen consumption and MMP. Methods The mitochondria of rat brain were isolated by centrifugation. Mitochondria oxidative respiratory consumption was measured by Clark electrode after the treatment of GDP at different concentrations so as to calculate mitochondrial state 3 respiration (ST3), mitochondrial state 4 respiration (ST4), respiratory control rate (RCR), and the rate of oxidative phosphorylation (OPR). MMP was detected by Rhodamine 123 method at the different concentrations of GDP. Results With the increase of GDP concentration form 0 to 1.0 mmol/L, the values of ST3, ST4 and OPR were reduced while RCR was elevated. But when the concentration increased to 1.4 mmol/L, the former 3 indexes begun to increase while the later declined. When the GDP concentration reached to 1 mmol/L, the inhibitory rate was only 35.1%, 51.3%, 14.2% to ST3, ST4 and OPR respectively, while RCR was increased to 133.2%. No matter the concentration was over 1 mmol/L or under 1 mmol/L, the ability of inhibition was attenuated. MMP reached to the highest point when GDP exerted the highest inhibitory rate on mitochondrial respiratory oxygen consumption. Conclusion GDP, an inhibitor of UCPS, can regulate the respiratory oxygen consumption and MMP of the isolated rat brain mitochondrial directly in a dose-effect fashion. The change of UCPS activity can affect the respiratory oxygen consumption and MMP.

Objective To investigate the pathologic characteristics of skip metastases of mediastinal lymph node in lung cancer. Methods Of 398 lung cancer patients who underwent radical resection and extensive lymph node dissection. 47 patients were diagnosed as with skip N 2 metastases, and their mediastinal lymph nodes were analyzed. Results The skip N 2 metastases of lung cancer appeared as single group or multi-group. The commonest metastatic site was the 7th group lymph node (28.4%), then the 4th, 3rd and 5th group, rating 24.2%, 15.8% and 10.5%, respectively. For cases with squamous cell carcinoma or adenocarcinoma, no any skip N 2 metastasis occurred for the tumor less than 1 cm in diameter, for tumor greater than 1 cm in diameter, the skip N 2 metastasis increased with tumor size. The incidence skip N 2 metastasis of low-grade differentiated adenocarcinoma was significantly higher than high-grade differentiated adenocarcinoma (P

AIM:To observe the effect of GDP on uncoupling proteins(UCPs) activity and the efficiency of oxidative phosphorylation in hypoxic exposed rat brain mitochondria.METHODS: Adult SD rats were randomly divided into three groups (control, acute hypoxia and chronic hypoxia groups). The animals were placed into a hypobaric chamber simulated 5 000 m high altitude for 0, 3 and 30 d, respectively. The mitochondria from rat brain were isolated by centrifugation. The activity of UCPs was detected by the method of [H3]-GTP binding with UCPs specifically. The maximal binding content (Bmax) and the dissociation constant (Kd) were determined by Scatchard plot. The mitochondrial potential was measured by rhodamine 123 method. Oxidative respiratory consumption was measured by Clark electrode. The experiments were conducted under the conditions with or without GDP (1 mmol/L), respectively. RESULTS: For exposed to hypoxia, Bmax and the oxidative consumption of uncoupling respiration were increased. Kd, MMP and RCR were decreased. UCPs activity was inhibited by GDP in three groups. Kd was increased 61.01%, 83.13% and 71.52% and Bmax was decreased 23.18%, 35.20% and 33.38%, respectively. The values in the acute hypoxic group were changed markedly. The sensitivity of UCPs to GDP was elevated significantly by hypoxia. With the reducing of UCPs activity, oxidative consumption of uncoupling respiration was decreased whereas RCR and MMP were increased. The results elucidated increase in the efficiency of oxidative phosphorylation.CONCLUSION: GDP increases the mitochondrial membrane potential and decreases the oxygen consumption of uncoupling respiration in hypoxic exposed rat brain mitochondria by inhibiting UCPs activity. The results suggest that the change in UCPs activity is one of the factors of mitochondrial dysfunction in oxidative phosphorylation induced by hypoxia.

Objective: To investigate the effect of electroacupuncture (EA) on cognitive function in D-galactose (D-gal)-induced aging rats, and the correlation between the effect and nucleotide-binding oligomerization domain (NOD)-like receptor protein 3 (NLRP3)-ASC-Caspase-1 signaling pathway. Methods: Forty-six male Sprague-Dawley (SD) rats were randomly divided into a control group (n=10), a model group (n=12), an EA-7 d group (n=12) and an EA-21 d group (n=12). Except the control group, the other three groups received 42 consecutive days of intraperitoneal injection of D-gal to establish aging rat models with cognitive dysfunction. The control group received the same amount of normal saline via intraperitoneal injection. Two EA groups were given EA therapy for 21 consecutive days (began from the 22nd day of modeling) or 7 consecutive days (began from the 36th day of modeling) accordingly at Dazhui (GV 14), Baihui (GV 20), Shenshu (BL 23) and Zusanli (ST 36). After modeling/ intervention, all four groups received behavioral evaluations by Morris water maze (MWM) test, novel object recognition (NOR) test and step-down passive avoidance (SDPA) test followed by the Western blot (WB) detection of the expression levels of hippocampal NLRP3 inflammasome-associated proteins NLRP3, ASC and Caspase-1. Results: MWM (place navigation test, PNT) results showed that the escape latency in the model group was significantly longer than that in the other three groups (P<0.05), and there was no significant difference among the other three groups on the 1st day of the test (P>0.05). From the 2nd day to the 4th day of the test, there was no significant difference between the EA-21 d group and the control group (P>0.05) in the escape latency; the escape latency was significantly shorter in the EA-21 d group than in the model group and the EA-7 d group (P<0.05). MWM (spatial probe test, SPT) results showed that the time spent in the target quadrant was significantly shorter and platform crossover number was significantly lower in the model group than in the other three groups (P<0.05). The time spent in the target quadrant was longer in the EA-7 d group than in the model group (P<0.05), but was shorter than that in the control group and the EA-21 d group (P<0.05). There was no significant difference in the swimming speed among the four groups (P>0.05). NOR results showed that there was no significant difference in the recognition ratio between the EA-7 d group and the EA-21 d group (P>0.05), and the recognition ratio was significantly higher in the two EA groups than in the model group (P<0.05), but was lower than in the control group (P<0.05). SDPA results showed that the electric shock number was higher in the model group than in the other three groups (P<0.05), and the differences among the other three groups were statistically insignificant (P>0.05). The model group had the shortest step-down latency, followed by the EA-7 d group, the EA-21 d group and the control group in order (P<0.05). The WB results indicated that the expression level of NLRP3 was significantly lower in the control group and the EA-21 d group than in the model group and the EA-7 d group (P<0.05). The expression levels of ASC and Caspase-1 were significantly higher in the model group than in the other three groups (P<0.05), and there was no significant difference among these three groups (P>0.05). Conclusion: NLRP3 inflammasome may be involved in the development of cognitive decline in aging rats; 7 consecutive days of EA intervention can partially improve the cognitive impairment in aging rats though the effect is rather limited; 21 consecutive days of EA intervention may improve the learning and memory abilities in aging rats via downregulating the expression levels of NLRP3 inflammasome-associated proteins in hippocampus.

AIM:To elucidate whether ZFP580 is involved in the cardioprotective effects of hypoxic precondi-tioning (HPC) against hypoxia-reoxygenation (H/R) injury in H9c2 myocardial cells.METHODS: Rat heart-derived H9c2 cells were cultured in DMEM .H/R was induced by incubation under ischemic hypoxia for 3 h and reoxygenation for 2 h.HPC was induced by exposing the H 9c2 cells to 10 min of hypoxia and 20 min of reoxygenation for 3 cycles before H/R treatment.MTT staining and LDH leakage detection were used to evaluate the effects of HPC .Western blotting was used to detect the protein levels of ZFP580, phosphorylated ERK1/2 and cleaved caspased-3.The effects of ZFP580 overexpre-ssion or knockdown on H/R induced apoptosis were determined .RESULTS:The results of MTT staining and LDH leakage detection showed evidence of HPC cytoprotection against H /R-induced cell death in H9c2 cells.ZFP580 protein level and ERK1/2 phosphorylation were significantly increased in the HPC group compared with control group and H /R group. PD98059, an inhibitor of ERK1/2 phosphorylation , significantly suppressed the HPC-induced up-regulation of ZFP580 pro-tein expression.ZFP580 overexpression significantly inhibited apoptosis and caspase-3 activation in H9c2 cells.CON-CLUSION:HPC exhibits cytoprotection against H/R and leads to high level of ZFP 580 protein in H9c2 cells.ZFP580 is regulated by ERK1/2 activation and mediates the anti-apoptotic effect of the ERK1/2 signaling pathway in HPC cytoprotec-tion.

Aim To investigate the effects of emodin on the contraction of gallbladder smooth muscle(GBSM)and the L-type calcium current in GBSM cells.Methods Gallbladder muscle strips were obtained from adult guinea pigs and the resting tension was recorded.Gallbladder smooth muscle cells were isolated by enzymatic digestion,and calcium current was recorded by the whole-cell patch clamp method.Results Emodin-induced contraction of GBSM was significantly attenuated by pretreatment with nifedipine.Emodin increased the L-type calcium current in a dose-dependent manner.When 10 ?mol?L-1 emodin was applied to GBSM cells,the amplitude of L-type calcium current at +10 mV was enhanced by(45.2?2.26)%.In the presence of PKC inhibitor,staurosporine,emodin did not significantly affect the calcium current.Conclusion Emodin enhances L-type calcium current via PKC-dependent pathway and promotes gallbladder contraction.
