Objective To investigate the safety and feasibility of laparoscopy-assisted radical gastrectomy in elderly gastric cancer patients aged over 70 years.Methods Clinical data of 222 elderly gastric cancer patients aged over 70 years receiving surgery from January 2010 to January 2015 were retrospectively analyzed.Patients were divided into the laparoscopy-assisted radical gastrectomy group (LAG group,n=106) and the conventional open gastrectomy group (OG group,n=116),depending on the surgery type.General information,surgical parameters,intra-operative blood pressure fluctuations & blood gas analysis,postoperative recovery and complication rates were compared between the two groups.Results There were no significant differences between the two groups in gender,age,preoperative coexisting diseases,tumor size and location,TNM staging or extent of resection (all P＞0.05).Compared with the OG group,blood loss (86.9±38.9) ml vs.(168.8±49.1) ml,t=10.923,P＜0.01),operative incision length [(9.20±1.55) cm vs.(16.50± 2.12) cm,t=8.788,P＜0.01],time to bowel function recovery [(3.20±1.09) d vs.(5.50±1.16) d,t=4.590,P＜0.01],hospital stay [(11.82±3.92) d vs.(16.14±4.69) d,t=2.234,P＜0.05] and postoperative complications (12.3％ vs.26.4％,x2 =5.186,P＜0.05) were reduced in the LAG group.The LAG group had higher levels of partial pressure of carbon dioxide in arterial blood (PaCO2) and lower levels of base excess than the OG group [(48.10±5.53) mmHg vs.(40.25± 4.66) mmHg,(-7.45±3.72) mmol/L vs.(-3.35±1.98) mmol/L,t=6.908 and 3.619,P＜ 0.01 and 0.05].However,there were no significant differences between the two groups in partial pressure of oxygen (PaO2),arterial oxygen saturation (SaO2) or hydrogen ion concentration (all P＞ 0.05).No significant differences in operation time or number of retrieved lymph nodes were found between the two groups [(196.1 ± 23.4) min vs.(184.2 ± 26.9) min,(28.7 ± 6.5) vs.(27.3 ± 5.6),t=1.174 and 0.515,both P＞0.05].Conclusions Laparoscopy-assisted radical gastrectomy is safe and practical in elderly patients aged over 70 years with gastric cancer and can achieve comparable effects of open radical gastrectomy with less invasiveness and faster recovery.

Effects of Pb,Zn,Cu and Cd on growth and enzyme activities of microorganisms such as Bacillus licheniformis 2709,Bacillus subtilis1.398 and Aspergillus usamii 537,which can individually produce alka-line,neutral and acid protease,were studied,respectively. By determining growth and enzyme activities of three bacterial species,as well as analyzing their tolerance and resistance indicators(MTC and MIC) using growth inhibition plate analysis(GIPA) under different heavy metal gradients,results showed that four heavy metals under higher than a special concentration level significantly inhibited growth and enzyme ac-tivities of three species. The alkaline protease exhibited greatest adaptability to four heavy metals,next the neutral protease also exhibited certain adaptibilty to Zn and Cd,whereas the acid protease was totally inhib-ited under any levels of heavy metal concentrations. Three species not only showed great potential to tolerate and resist toxicity of lead and zinc(2.0 mmol/L-6.0 mmol/L) ,but also showed certain resistance to cad-mium(0.5 mmol/L-0.75 mmol/L) .

Objective The core mechanism of renal insterstitial fibrosis (RIF) is epithelial-mesenchymal transition.This study aimed to investigate the effect of erythropoietin on high glucose-induced epithelial-mesenchymal transition ( EMT) of normal hu-man kidney proximal tubular epithelial cells (HK-2) and its possible mechanism. Mothods HK-2 cells cultured in vitro were ran-domly divided into a blank control group , a high glucose induction group , a mannitol induction group , an EPO induction group , an EPO (5, 10, and 20U/mL) inhibition group, and an Rho kinase inhibitor group.After 24 hours of intervention, the mRNA levels of RhoA and ROCK were determined by RT-PCR, those of E-cadherin and α-smooth muscle actin (α-SMA) proteins detected by immu-nofluorescence staining , and the expression of FN proteins in the supernatant measured by ELISA . Results Compared with the blank control group , the expressions of RhoA and ROCK 1 mRNA were significantly increased in the high glucose induction group (0.945 ±0.132 vs 1.400 ±0.022, 1.007 ±0.002 vs 1.913 ±0.011, P<0.05), but markedly decreased in the 5, 10, and 20U/mL EPO inhibition groups (1.400 ±0.022 vs 1.278 ±0.006, 1.400 ±0.022 vs 0.770 ±0.005, 1.400 ±0.022 vs 0.334 ±0.009, P<0.006) in comparison with the high glucose induction group , and the effects were related to the concentration of EPO .Compared with the blank control, the expression of E-cadherin protein was increased in the high glucose induction group (0.644 ±0.006 vs 0.107 ± 0.004, P<0.05), but remarkably decreased in the 5, 10, and 20 U/mL EPO inhibition groups (0.236 ±0.006, 0.433 ±0.010, 0.521 ±0.010) in comparison with the high glucose induction group (P<0.05), and the effects were also related to the concentration of EPO.Pearson correlation analysis showed a positive correlation between the mRNA expressions of RhoA and ROCK 1 in the high glu-cose induction and EPO inhibition groups . Conclusion EPO can inhibit high glucose-induced epithelial-mesenchymal transition of normal human kidney HK-2 cells and thus delay renal fibrosis , which mignt be related to the RhoA/ROCK signaling pathway .

Objective To explore the relationship of delivery of parenteral fat emulsion and lipid peroxidation,and to observe the safety and effectiveness of parenteral nutrition(PN)in infants with very low birth weight(VLBWI).Methods Thirty infants with VLBWI were randomly divided into 3 groups:the preterm infants received pareneral nutrition containing amino acids and dextrose and soluvit,while intralipid provided separately,intralipid were light exposed(group A,n=10)or light protected(group B,n=10).In group C(n=10),soluvit and vitlipid were co-administered with intralipid and light protected.All the prematures received PN for 7 days and 10 cases of VLBWI not recei-ving PN were collected as control group.Anti-oxidation level,ascorbate,blood glucose,oxygen saturation,serum biochemistry index and body weight were determined before and after experiment.Results Seven days after PN,the MDA concentrations in the test groups all increased(⊿dA was the most,⊿dB was the next,⊿dC was the least).For superoxidedimutuse(SOD)reduction concentrations,⊿dA decreased sharply,then was ⊿dB,⊿dc decreased little,The blood Vit C increase in group B and C were more than group A.Significant changes of MDA,SOD and Vit C existed among the group B,C and A.In the 3 test groups,bilirubin,albumin,prealbumin concentrations were higher after the experiment,but there were no significant changes compared with control group.No significant changes in blood biochemistry,oxygen saturations were found before and after the observation in every group.Conclusions Multivitamin preparations protect fat emulsion against light-induced formation of lipid hydroperoxides,and administering multivitamins with fat emulsion via dark delivery tubing provide a practical way of preventing peroxidation of the lipid while limiting vitamin loss.Furthermore,it is relatively safe to apply fat emulsion intravenously with suitable dose and infusion rate for a few days to VLBWI from the second day of birth who require partial parenteral nutrition.

This research explored the synergistic effects and the potential mechanisms of RCE-4 and various nonsteroidal anti-inflammatory drugs (NSAIDs) on the proliferation of cervical cancer Ca Ski cells. The MTT assay and CalcuSyn V2.0 software were used to detect cell proliferation and calculate the combination index (CI); the expression levels of various proteins were analyzed using Western blot assay; mitochondrial membrane potential (MMP) was assessed using JC-1 staining; acridine orange/ethidium bromide (AO/EB) double-fluorescence staining was used to detect the apoptosis of Ca Ski cells; a co-immunoprecipitation (Co-IP) assay was used to analyze the relative content of Bcl-2-Beclin 1 complex in Ca Ski cells. The results demonstrate that the combination of RCE-4 and NSAIDs increases the inhibition of Ca Ski cells compared to the single-RCE-4 group, and celecoxib provided the best synergistic effect among the four NSAIDs tested, with a CI of 0.32. The combination of RCE-4 and celecoxib significantly down-regulated the expression of cyclooxygenase-2 (COX-2) and nuclear transcription factor-κB (NF-κB), and promoted the expression of non-steroidal anti-inflammatory drugs activity gene-1 (NAG-1). In addition, autophagy induced by RCE-4 was markedly inhibited in combination with celecoxib, which was associated with down-regulation of the expression of microtubule-associated protein 3 (LC3)-II, Beclin 1, p62 and autophagy-related gene (ATG) 3/4B/5/7/14. RCE-4-induced apoptosis was significantly enhanced by altering the depolarization of mitochondrial membrane potential and the expression of B cell lymphoma-2 (Bcl-2), B cell lymphoma-xl (Bcl-xl), Bcl-2 associated X protein (Bax), Bcl-2/Bcl-xl-associated death promoter (Bad) and cleaved cysteinyl aspartate specific proteinase (cleaved-caspase) 3/7/9. Furthermore, the formation of the Bcl-2-Beclin 1 complex was significantly inhibited in Ca Ski cells treated with RCE-4 in combination with celecoxib. Taken together, this research shows that the combination of RCE-4 and celecoxib has a significant synergistic effect on the proliferation of Ca Ski cells by promoting apoptosis, inhibiting autophagy and disturbing the formation of the Bcl-2-Beclin 1 complex, which may be a novel strategy to increase the sensitivity of anti-cervical cancer drugs.
