Acute kidney injury (AKI) is caused by a variety of causes resulting in rapid decline in renal function and manifestingclinical syndrome, whether mild or severe kidney damage it caused, the permanent loss of renal function will exist; the mortality of patients with septic AKI is as high as over 70%. Renal replacement therapy (RRT) can significantly improve the clinical prognosis of patients with AKI and reduce its mortality. However, the selections of RRT treatment mode, dose and timing of start or stop exist a lot of controversies. In this report, as using RRT to treat critically ill patients with AKI is still a hot topic in academic research, the related literatures of RRT guidelines, score evaluation, renal function indexes and biological marker aspects were reviewed and summarized.

Objective To investigate the antitumor effects and the possible mechanisms of dendrit-ic cells co-cultured with cytokine-induced killer cells(DC-CIK)in combination with sorafenib on two lung adenocarcinoma cell lines,A549 cells(harboring KRAS gene mutation)and PC-9 cells(harboring EGFR gene mutation). Methods DC and CIK cells were routinely generated in vitro by stimulating PBMCs isola-ted from lung cancer patients with different cytokines and then co-cultured after a week of culturing. Flow cy-tometry analysis(FCM)was used to analyze the phenotype of DC-CIK cells after 7 days of co-culturing. The 50% inhibitory concentration(IC50 )of sorafenib against tumor cells was detected by MTT assay. The tumor cells were treated with DC-CIK cells alone or in combination with sorafenib. The proliferation of tumor cells was tested by CCK-8 kit and dynamically monitored by real-time cellular analysis(RTCA). Annexin-V/ PI staining was used to examine the apoptosis rates in each group. Real-time fluorescent quantitative PCR and FCM were respectively performed to detect the expression of natural killer group 2 member D ligands (NKG2DLs)at mRNA and protein levels after the treatment with sorafenib for 24 h. Results There was no significant difference between the IC50 of sorafenib against A549 and PC-9 cells after a 24-hour exposure(P﹥0. 05). Compared with the DC-CIK biotherapy,treating the tumor cells with DC-CIK cells in combination with sorafenib significantly inhibited the cell proliferation and increased the total apoptosis rates of tumor cells(P﹤0. 05). Moreover,the inhibition rates to tumor cell proliferation were enhanced along with the in-crease of effect-to-target ratio(E/ T). Compared with the single-factor treatment groups,the normalized cell index(NCI)in the combined treatment group was significantly decreased. Blocking NKG2D could abate the inhibitory effect of DC-CIK cells on tumor cell proliferation(P﹤0. 05). The expression of NKG2DLs(inclu-ding ULBP1,UBLP2 and ULBP3)on tumor cells at mRNA and protein levels were increased to different ex-tent after treating with 5 μmol/ L of sorafenib for 24 h. Conclusion There was no significant different be-tween the inhibitory effects of sorafenib on the proliferation of lung adenocarcinoma cancer cells harboring KRAS or EGFR gene mutation. The antitumor effects of DC-CIK cells combined with sorafenib on lung ade-nocarcinoma cells might be induced by regulating the NKG2D-NKG2DLs pathway and enhancing apoptosis. Moreover,the antitumor effects of the combined treatment were better than those of single-factor treatments.

In order to optimize acupuncture treatment protocol for functional defecation disorders, literature during past 20 years is reviewed, and factors which influences acupuncture therapeutic effect are analyzed from aspects of acupoint, acupuncture technique, etc. As for the selection of acupoint, more attention should be paid on the use of Baliao, especially Zhongliao (BL 33) and Xialiao (BL 34); when Baliao is deeply needled, it is essential to acquire scientific technique. The relationship between acupuncture parameter (including electroacupuncture waveform and frequency), acupuncture techniques (including reinforcing and reducing technique, quantity of stimulation, etc. ) and acupuncture efficacy is complicated, and the scientific values of present research conclusion are in need, of further improvement. The diagnosis and treatment awareness on types of functional defecation should be strengthened, and the mental health of the constipation patients should be concerned. The combination of acupuncture and biofeedback training can have a synergistic effect, which is benefit to achieve a better long-term effect. Based on this, acupuncture treatment protocol for functional defecation disorders can be optimized to further improve the efficacy.

BACKGROUND: Zinc, an inorganic antibacterial material, has a suitable degradation rate and good antibacterial property. Adding alloying elements can improve the mechanical properties and biocompatibility of the material, which is the development direction of novel medical biodegradable metal materials. There is still lack a comparable research on the antibacterial properties among zinc-based materials. OBJECTIVE: To investigate the antibacterial properties of pure zine and zinc-based alloys in vivo. METHODS: Eighty Sprague-Dawley rats, SPF grade, were randomized into two groups (n=40/group) , and all rats were injected with Staphylococcus aureus or Escherichia coli solution to prepare infection models. Different materials (Zn, ZnAl, ZnSr, Zn3 Mg, Zn3 Ag, Zn3 Ca and Zn4 Cu; five rats for each material) were implanted into the medullary cavity of femur. The control group without any material was set. At 1, 4, 7 and 14 days after implantation, the changes of body temperature, white blood cell count, serum tumor necrosis factor α and serum zinc content in rats were detected. The secretions and tissues of the surgical site were collected to identify the bacterial species. RESULTS AND CONCLUSION: (1) The body temperature in all the rats was increased to different extents after bacterial infection, but the temperature of the rats implanted with zinc and zinc alloys was always lower than that in the control group at 7 and 14 days (P < 0.05) . The temperature in the Zn3 Ag group was significantly lower than that in the other groups at 7 and 14 days (P < 0.05) . (2) The white blood cell count and tumor necrosis factor α level in the zinc and zinc alloys groups were significantly lower than those in the control group at 7 and 14 days after implantation (P < 0.05) . The white blood cell count and tumor necrosis factor α level in the Zn3 Ag group were significantly lower than those in the other groups (P < 0.05) . (3) The serum zinc content in all groups has no significant difference (P> 0.05) . (4) The bacterial culture results showed S.aureus (+) in the Staphylococcus aureus infection group and E.coli (+) in the Escherichia coli infection group. (5) To conclude, degradable zinc-based alloys exert marked antibacterial effects, and Zn3 Ag alloys have the best antibacterial activity.

Objective: To explore the relationship between the muscle mass index (MMI) and the aggregation of cardiovascular risk factors (CVRFs) in children and adolescents, and to provide a scientific basis for the prevention and treatment of cardiovascular diseases in children and adolescents. Methods: The current situation study design was adopted, and 1 622 children and adolescents aged 12-17 years old in Yinchuan City were selected by a cluster random sampling method. All subjects were subjected to questionnaire survey, physical examination, body composition determination and laboratory index testing. Results: When other variables were not adjusted, MMI was a risk factor for the aggregation of cardiovascular risk factors ( P <0.01). After adjusting for age, gender and BMI, MMI became a protective factor for CVRFs≥1 ( OR =0.74, 95% CI =0.62-0.89), compared with insufficient MMI, the risk of developing CVRFs≥1 with good MMI and sufficient MMI was 0.60(95% CI =0.46-0.79), 0.56(95% CI =0.37- 0.85 ) times. The risk of CVRFs≥2 was 0.54(95% CI =0.37-0.79), 0.51(95% CI =0.30-0.87) times, and similar results were found in boys ( P <0.05). Conclusion Under the same BMI level, muscle mass index is a protective factor for cardiovascular risk factor aggregation in children and adolescents. Physical exercise of children and adolescents should be emphasized to maintain the best muscle mass and weight.
