To investigate the effect of recombinant human growth hormone (rhGH) on JAK2-STAT3 pathway and the growth of gastric cancer cell lines at different GHR expression status, the eukaryotic expression vector targeting human GHR (pGPU6/GFP/Neo-shGHR and pGPU6/GFP/Neo-scramble) was constructed and transfected into MGC803 cells by Lipofectamine 2000. Stable expressive cell lines were obtained by G418 screening. The expression of GHR was analyzed by Western blotting. After being stimulated with rhGH, cell growth was detected by MTT assay. Cell cycle and apoptosis were examined by flow cytometry. The components of JAK2/STAT3 signaling pathway were detected by Western blotting. There is no significant difference of GHR expression between MGC803 and pGPU6/GFP/Neo-scramble-transfected cells (named as MGC803-NC) (P > 0.05). Compared with MGC803, the GHR expression in pGPU6/GFP/Neo-shGHR-transfected cells (named as MGC803-shGHR) decreased significantly (protein decreased 50%). The cells were treated with rhGH at 0, 150 and 300 ng x mL(-1), the growth rate of MGC803 and MGC803-NC increased significantly, PI and the number of G2/M phase cells all increased significantly, and apoptosis decreased significantly. Western blotting revealed that the expression of pJAK2 and pSTAT3 was up-regulated after being treated with rhGH in MGC803 and MGC803-NC cells. In contrast, similar change was not observed in MGC803-shGHR cells. Knockdown of GHR gene may decrease the sensitivity of gastric cancer cells to rhGH, and down-regulating of components of the expression of JAK2/STAT3 signaling pathway may be the potential mechanisms.

Astract:Objective To compare the clinical efficacy of minimally invasive percutaneous osteosynthesis and supercutaneous plating with closed reduction in the treatment of distal tibial comminuted fractures. Methods A total of 40 patients with close distal tibial comminuted fractures in our hospital from April 2012 to April 2014 were divided into minimally invasive percutaneous osteosynthesis group and external fixation group. External fixation group were treated by supercutaneous plating,while the minimally invasive percutaneous osteosynthesis group were treated by minimally invasive percutaneous osteosynthesis. And the operative duration,hospital stay,the time of weight loading and frac-ture healing,postoperative complications and function of ankle were compared between the two groups. Results In the supercutaneous plating group,the operative duration was (60. 17 ± 5. 64) minutes,the hospital stay was (8. 651 ± 2. 21) days,the time of weight loading was (49.26 ±9.85)days,the time of fracture healing was (13.82 ±4.23)weeks,the incidence of postoperative complications was 5.00%,and the excellent and good rates was 95. 00%. In the minimally invasive percutaneous osteosynthesis group,the operative duration was (74. 64 ± 6. 82)minutes,the hospital stay was (18. 22 ± 2. 32)days,the time of weight loading was (57. 56 ± 11. 32)days,the time of fracture healing was (17. 47 ± 2. 31)weeks,the incidence of postoperative complications was 25. 00%,and the excellent and good rates was 80. 00%. There were significant differences in operative duration(χ2 =9. 922,P=0. 007),hospital stay(χ2 =10. 48,P=0. 015),time of weight loading (χ2 =14. 618,P=0. 001) and fracture healing(χ2 =40. 16,P=0. 000) between the two groups. The AOFSA score of supercutaneous plating group was (89. 1 ± 3. 9)point,compared with (90. 5 ± 4. 1)point of minimally invasive percutaneous osteosynthesis group,and the difference was statistically significant(χ2 =0. 463,P=0. 793). Conclusion Distal tibial fractures may be treated successfully with minimally invasive plate osteosynthesis or supercutaneous plating. However,supercutaneous plating offers multiple advantages in terms of mean operative dura-tion,hospital stay,the time of weight loading and fracture healing.

Objective To investigate the change in GABA receptor-activated current in dorsal root ganglion (DRG) neurons in rats with neuropathic pain. Methods Twenty adult SD rats of both sexes weighing 100-150 g were randomly divided into 2 gorups: sham operation group (group S, n = 5) and neuropathic pain group (group NP, n= 15). Neuropathic pain was induced by ligation of right L5 spinal nerve. The animals were sacrificed at 5 days after operation. The L5 DRG( neurons in group NP and L3-5 DRG neurons in group S were immediately isolated. Whole-cellpatch- clamp technique was used. The extracellular solution contained GABA 100μmol/L.The frequency and amplitude of the GABA-activated current in DRG neurons and the changes in action potential (threshold potential, rheobase and overshoot) and resting potential before and after GABA administration were recorded. Results GABA 100μmol/L induced rapid inactivation of inward current in most neurons. Compared with the baseline before application of GABA, in group S GABA induced depolarization,increased resting potential and decreased amplitude and rheobase of action potential in large and medium DRG neurons, while in group NP GABA increased resting potential but induced no significant change in threshold potential and rheobase and overshoot of action potential. The frequency and amplitude of GABA-activated current and the degree of change in resting potential and rheobase and overshoot of action potential were significantly lower in group NP than in group S.Spontaneous discharge occurred in small DRG neurons in both groups. No GABA-activated current was observed in all DRG neurons with spontaneous discharge. Conclusions Neuropathic pain is induced by decreasing GABA-mediated inhibition signals in large and medium DRG neurons leading to increased excitability of neurons.

Objective To study the protective mechanism of astragaloside on skin photoaging. Methods BALB/c mice were randomly divided into four groups: model group irradiated with ultraviolet rays (UV), model plus matrix group pretreated with the matrix before UV irradiation, model plus astragaloside group pretreated with astragaloside 0.08% cream before UV irradiation, normal control group received no irradiation or pretreatment. After 4-week irradiation, the mice were sacrificed, and skin tissues were resected from the back of these mice. Then, reverse transeription PCR (RT-PCR) and immunohistochemistry were performed to detect the mRNA and protein expression of TGF-βR Ⅱ and Smad 7, respectively. Gray scale ratio was used to represent the mRNA levels of TGF-βR Ⅱ and Smad 7. Results There was a significant difference in the mRNA level (F = 80.98, 736.80, respectively, both P < 0.01) and protein positivity rate (F = 45.36,132.25, respectively,both P < 0.01) of TGF-βR Ⅱ and Smad 7 among the 4 groups. The mRNA level and protein positivity rate of TGF-βR Ⅱwere 0.2588±0.0283 and (28.20 ± 5.24)% respectively in the model group, significantly lower than those in the normal control group[0.5688 ± 0.0439, (53.00 ± 4.72)%, both P < 0.01] and model plus astragaloside group [0.3767 ± 0.0374, (41.64 ± 2.59)%, both P< 0.01]; on the contrary, the mRNA level and protein positivity rate of Smad 7 in the model group [0.8637 ± 0.0514, (82.06 ± 2.18)%] were significantly higher than those in the normal control group [0.5900 ± 0.0585, (47.50±3.81)%, both P < 0.01] and model plus astragaloside group [0.7131 ± 0.0410, (64.36 ± 2.62)%, both P< 0.01]. In the model plus astragaloside group, the mRNA level and protein positivity rate of TGF-βR Ⅱ were significantly higher than in the model plus matrix group [0.2653 ± 0.0456, (28.74 ± 2.28)%, both P < 0.01], while those of Smad 7 were statistically lower than in the model plus matrix group [0.8553 ± 0.0575, (82.62 ± 4.02)%, both P < 0.01]. However,no significant difference was observed in the mRNA level or protein positivity rate of TGF-βR Ⅱ or Smad 7 between the model group and model plus matrix group (all P > 0.01). Conclusion Astragaloside can prevent skin photoaging by the alteration of TGF-β pathway via up-regulating TGF-βR Ⅱ expression and down-regulating Smad 7 expression.
