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.

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 .

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.

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 understand the molecular epidemiology characteristics and its drug resistance of methicillin-resistant Staphylococcus aureus (MRSA) in the urban area of Jilin and to provide important basis for guiding the clinical medication and prevention of the MRSA infection. Methods One hundred and three strains of MRSA from July 2013 to July 2014 in the urban area of Jilin were selected. The polymerase chain reaction (PCR) technology and multiple polymerase chain reaction were used to detect mecA gene and Staphylococcus chromosomal cassette mec typing (SCCmec) genotype of MRSA. The drug sensitivity test for 13 kinds of clinical common antibacterial drugs were detected by using the K-B method. And the source of the strains were analyzed. Results The results of SCCmec genotype of MRSA showed that SCCmecⅢtype were 62 strains, accounting for 60.2%;SCCmecⅡtype were 39 strains, accounting for 37.9%; failing to parting were 2 strains,accounting for 1.9%. Drug susceptibility test results showed that all of 103 MRSA strains were resistant to cefoxitin, cefazolin, penicillin and benzene, and drug resistance rate was 100.0%. The resistant rate to erythromycin, levofloxacin, ciprofloxacin, tetracycline, gentamicin and rifampin were 96.1%, 93.2%, 95.1%, 91.3%, 90.3%and 55.3%receptively;the resistant rate to sulfamethoxazolewas was only 1.9%;and the resistant strains to vancomycin and teicoplanin were not detected. The top three department of the distribution of the strains source were department of neurosurgery (31.1%), ICU (19.4%) and burn plastic surgery (17.5%). Conclusions The SCCmecⅢtype is the main MRSA epidemic strains, and SCCmec type II is a minor epidemic strainin the urban area of Jilin. The antibiotic resistance of MRSA is a serious problem with multiple drug resistance, but MRSA is sensitive to vancomycin and teicoplanin.

Objective To study the effect of rhu-IFN-? on immune state and vertical transmission in pregnant mice infected with Toxoplasma gondii. Methods Sixty pregnant BALB/c mice were randomly divided into three groups: a control group,infected group and treatment group. In the infected group and treatment group,each mouse was injected with T.gondii tachyzoites peritoneally on the day 8 of gestation. In the treatment group,each mouse was treated with 1 000 U rhu-IFN-? on the day 7,8,9 of gestation. Blood was collected from the tail veins of all the mice on the day 10,12 of gestation. The levels of blood CD4+ and CD8+ T cells were detected by flow cytometry. Meanwhile,on the day 12 of gestation,all mice were anatomized to observe live embryo rate and the infection status in fetal brain tissue. Results Compared with the control group,the levels of CD4+ T cells in the infected group and treatment group were low,and the levels of CD8+ T cells high on the day 10,12 of gestation,so the ratio of CD4+/CD8+ was inversed. However,compared with the infected group,the levels of CD4+ T cells in the treatment group were high and the levels of CD8+ T cells low on the day 10,12 of gestation,so the ratios of CD4+/CD8+ were high on the day 10,12 of gestation. Meanwhile,the live embryo rate was high and the infection rate of intrauterine embryonic low. Conclusion A proper dose of rhu-IFN-? could improve the function of immunity system and reduce the vertical transmission probability in pregnant mice infected with T.gondii.
