Acute kidney injury (AKI) has emerged as a major public health problem that leads to decreased survival. Renal tubular epithelial cells are mainly damaged cells in AKI. Renal tubular epithelial cell remodeling plays a vital role in AKI. The regulatory mechanism of renal tubule remodeling is not yet clear. This review is written to address the renal tubule remodeling regulation mechanism of AKI.

Acute kidney injury(AKI) has emerged as a major public health problem that leads to decreased survival.In AKI,cell hyperplasia,hypertrophy and apoptosis are related to the cell cycle control.Two supervisory restriction points,G1/S and G2/M checkpoints,are responsible for cell-cycle control.Furthermore,cell cycle regulatory proteins are also involved in the regulation of the cell cycle in AKI.This review focuses on the cell cycle regulation mechanism of AKI.

Hereditary renal diseases (inherited kidney diseases) include glomerular diseases,tubular diseases and cystic diseases.The incidence of inherited kidney diseases is relatively low, but the variety of clinical insufficient understanding of the disease, the means test about inherited kidney diseases is also not standardized, easily lead to missed diagnosis and misdiagnosis.As the common clinical manifestation of hereditary renal disease and congenital/hereditary renal disease are mainly low blood potassium, kidney stones, polyuria, growth retardation, and may develop renal failure without treatment.Therefore, clinicians should pay special attention to the diagnosis of congenital/hereditary renal disease, and early interventions are recommended.

Psychological behavior training curriculum in military medical college was recon-structed after investigating psychological behavior training class in 45 military colleges. The measures taken included:establishing scientific management model, optimizing the teaching object and content, reforming the teaching method and improving multiple assessment methods. Self rating symptom scale symptom checklist 90(SCL-90) was used to test the psychological condition of students before and af-ter the teaching experiment. Results showed that seven factors were of statistical significance for stu-dents. Factors of fear and paranoia were statistically insignificant.

Parkinson's disease is a commonly encountered central nervous retrograde affection in elder persons. According to the theories of traditional Chinese medicine, Parkinson's disease is characterized by deficiency in the Ben (root) and excess in the Biao (branch). The Ben (root) is insufficiency of liver and kidney and deficiency of qi and blood; and the Biao (branch) is wind, fire, phlegm and stasis. Good therapeutic effects have been obtained by treatment based on syndrome differentiation, treatment with specific prescriptions and acupuncture. The further study on literatures, standardized criterion of symptoms differentiation and therapeutic effect determination as well as the screening and further research on the effective prescriptions and herbs should be paid more attention, meanwhile, the integration of herbs and acupuncture will be conducive to raise the therapeutic effect.

AIM:Toinvestigatetheassociationbetweenmethylationstatusofapoptosis-relatedgenesandche-mosensitivity in the lung adenocarcinoma cell line P 15.METHODS: Methylation-specific PCR was applied to detect the methylation status of p73, p14ARF, p16INK4a and bax genes of P15 cells in untreated control group and decitabine (DAC) treatment group.RT-PCR was used to detect the expression of p 73, bcl-xL, bad, bax, p14ARF and p16INK4a at mRNA level. Colony formation assay and cell growth inhibition assay were used to detect the sensitivity of P 15 cells to cis-diaminedichlo-roplatinum ( C-DDP) before and after DAC treatment .DAPI staining was used to determine the apoptosis of P 15 cells ex-posed to C-DDP before and after DAC treatment .RESULTS:p73, p16INK4a and bax were expressed in the methylation sta-tus.After DAC treatment, p16INK4a expression was decreased , and the expression of p73 and bax disappeared .The expres-sion of p73, p16INK4a and bax in the unmethylated status was weak , but the enhanced expression was observed following DAC treatment.After P15 cells were treated with DAC and C-DDP, the colony formation rate of the P15 cells was signifi-cantly decreased as compared with untreated control group .The apoptotic P15 cells in DAC+C-DDP treatment group were significantly higher than those in untreated control group (P<0.05).CONCLUSION:After treated with DAC, the sensi-tivity of P15 cells to C-DDP is increased due to the activation of silenced pro-apoptotic genes .DAC and C-DDP synergisti-cally promote tumor cell apoptosis .They have significant anti-tumor effect .

Objective To observe the clinical efficacy of grain-sized moxibustion plus acupuncture in treating plantar fasciitis. Method Forty patients with plantar fasciitis were randomized into a treatment group and a control group, 20 in each group. The treatment group was intervened by grain-sized moxibustion plus acupuncture, while the control group was by ordinary acupuncture. Visual Analogue Scale (VAS) was used to observe the morning heel pain degree before and after the treatment, and the clinical efficacies were compared.Result The VAS scores were significantly changed after treatment in the two groups (P<0.05). After treatment, VAS score in the treatment group was significantly different from that in the control group (P<0.05). The recovery rate and total effective rate were respectively 45.0% and 95.0% in the treatment group, versus 10.0% and 90.0% in the control group, and there was a significant difference in comparing the recovery rates (P<0.01).Conclusion Grain-sized moxibustion plus acupuncture is an effective method in treating plantar fasciitis.

Objective To detect the serum prohibitin protein(PHB)level in children with renal interstitial damage and analyze the correlation between PHB and renal interstitial fibrosis(RIF). Methods Serum PHB protein levels were determined by Western blot analysis in 36 children with kidney diseases,and 30 healthy children were studied as control. Levels of BUN,Scr,and urinary microprotein series(including ALBU/Cr,NAGU/Cr,IgG U/Cr,α1-MU/Cr)were studied by automatic biochemical analyzer. Renal interstitial damage was semiquantitatively graded according to Katafuchi's method. The correlation between serum levels of serum PHB protein and those of BUN,Scr as well as urine microprotein were analyzed. Results Serum PHB protein was positive in children with diverse kidney diseases however it was negative in the normal controls(P ＜ 0.05). Serum PHB levels were significantly higher in children with proliferative glomerulonephritis than those with non-proliferative glomerulonephritis(P ＜ 0.05). Statistical analysis indicated that serum PHB levels positively correlated with the degree of tubulointerstitial lesions(r ＝ 0.868,P ＜ 0.001)as well as the glomerular injuries(r ＝ 0.753,P ＜ 0.001). And,serum PHB levels were also positively correlated with urinary microprotein including NAG(r ＝ 0.586,P ＜ 0.001)and IgG(r ＝ 0.341,P ＜ 0.001). Conclusions Serum PHB levels were significantly increased in children with kidney diseases and were positively correlated with the degrees of renal interstitial damage,suggesting that PHB might be a potential clinical marker for detecting tubulointerstitial lesions.

Objective To establish an LC-MS/MS method for the detection of landiolol concentration in human blood.Methods After pretreatment with neostigmine and a deproteinization procedure, landiolol and the internal standard venlafaxine were eluted isocratically using a mobile phase consisting of acetonitrile and 10 mmoL·L-1 ammonium acetate with 0. 1% formic acid in a ratio of 3664 ( V/V ) . Separation of the respective compounds was achieved on a Waters XTerra? RP18 column (150 mmí4. 6 mm,5 μm). Quantitative analysis of landiolol was conducted by a triple-quadrupole mass spectrometer with positive-electrospray ionization source,monitored under a multiple reaction monitoring ( MRM) mode. The extracted ions monitored following MRM transitions were m/z 510. 5→423. 1 for landiolol and m/z 278. 2→215. 1 for the internal standard venlafaxine. ResultsThe calibration curve of landiolol in human blood showed good linear relationship in the range of 1. 010-2 020 μg·L-1 . The lower limit of quantitation was 1. 010 μg · L-1 . The RSD of within-day and between-day precision was less than 6. 5% and 4. 8%, respectively. The recovery rate was 92. 6%-100. 9%. Conclusion The method is proven to be simple,rapid and reliable,and can be applied to study the pharmacokinetics of landiolol hydrochloride in healthy Chinese volunteers.
