OBJECTIVETo examine whether the polymorphisms of endothelial nitric oxide synthase (eNOS) gene are associated with the susceptibility to high altitude pulmonary edema (HAPE) in Chinese railway construction workers at Qinghai-Tibet where the altitude is over 4 500 m above sea level.

METHODSA case-control study was conducted including 149 HAPE patients in the construction workers and 160 healthy controls randomly recruited from their co-workers, matching the patients in ethnicity, age, sex, lifestyle, and working conditions. Three polymorphisms of eNOS gene, T-786C in promoter, 894G/T in exon 7, and 27bp variable number tandem repeat (VNTR) in intron 4, were genotyped using polymerase chain reaction (PCR) and confirmed with DNA sequencing.

RESULTSThe frequencies of 894T allele and heterozygous G/T of the 894G/T variant were significantly higher in HAPE patients group than in the control group (P=0.0028 and P=0.0047, respectively). However, the frequencies of the T-786C in promoter and the 27bp VNTR in intron 4 were not significantly different between the two groups. Haplotypic analysis revealed that the frequencies of two haplotypes (H3,T-T-b, b indicates 5 repeats of 27 bp VNTR; H6, C-G-a, a indicates 4 repeats of 27 bp VNTR) were significantly higher in HAPE patients (both Pü0.0001). On the contrary, the frequencies of H1 (T-G-b) and H2 (T-G-a) were lower in HAPE patients than in healthy controls (both Pü0.001).

CONCLUSIONSTwo haplotypes (T-T-b and C-G-a) may be strongly associated with susceptibility to HAPE. Compared with the individual alleles of eNOS gene, the interaction of multiple genetic markers within a haplotype may be a major determinant for the susceptibility to HAPE.

Objective　The active protein of traditional Chinese medicine has anti-tumor effect, and salvia miltiorrhiza is an important anti-tumor traditional Chinese medicine. Here, the effect of Salvia miltiorrhiza lectin protein (SMLP) on the apoptosis of gastric cancer cells was studied.　Methods　SMLP expressed and purified from prokaryotic cells was used to treat the gastric cancer cells SGC-7901. The experiment was divided into the control group (untreated) and the SMLP treatment group (final concentration of 10 μmol / L of SMLP was treated for 24 h). Real-time RT-PCR and Western blot were used to detect the changes of apoptosis gene expression. Flow cytometry and Hoechst staining were applied to detect the apoptotic status. Caspase-3 and Caspase-9 activity assay kits were used to detect the apoptotic level.　Results　The result of RT-PCR showed that the mRNA level of Bax in the SMLP treatment group was significantly higher than in the control group (1.00±0.12 vs 0.67±0.10）(P<0.05). After treatment with SMLP to gastric cancer cells, the activity and expression level of cleaved Caspase-3 and Caspase-9 were increased significantly compared with the control group (P<0.05). The cell nucleus in the control group was bigger and rounder, with smooth surface and uniform staining, whilst in the SMLP-treated group, the cell nucleus became deeper with pyknosis, representing typical morphological characteristics of apoptosis. The early apoptosis level in the control group was 6.55%, and the SMLP treatment group reached 10.18%, showing an increase in the level of apoptosis.　Conclusion　SMLP expressed and purified in vitro can promote the apoptosis of gastric cancer cells, which is of great significance for further revealing the function of plant lectin and investigating the anti-tumor effect on the protein of traditional Chinese medicine.

Agarwood is a traditional and precious medicinal material and natural spice in China and other southeast Asian countries.As the head of all spices,agarwood has many pharmacological activities such as analgesia,antidiarrheal,anti-inflammatory and antibacterial effects. Due to its high price and scarce resources,there were just a few previous studies on it,mainly focusing on the chemical compositions of the agarwood essential oil and solvent extract mixture. The components of agarwood oils obtained by supercritical extraction and steam distillation were analyzed by using Gas Chromatography-Mass Spectrometer( GC-MS),and then the agarwood oils compositions and contents were compared between the traditional extraction method and the recently emerging supercritical extraction method. Antioxidant experiments of scavenging DPPH,ABTS,hydroxyl radical,total reducing power and MIC experiments of five kinds of tester strains such as staphylococcus aureus were combined to illustrate the differences between these two kinds of agarwood oils in terms of antioxidant and bacteriostatic activities. The results showed that the main components of agarwood oil were sesquiterpenoids( 68. 68%) in steam distillation extraction method,but sesquiterpenoids( 23. 78%) and chromones( 29. 42%) in supercritical extraction method. Fourteen common components included benzyl acetone,α-santalol,γ-eudesmol,agarospirol and guaiol etc. The antioxidant activity and inhibitory MIC of agarwood oils in supercritical extraction method were better than those in steam distillation method,and the inhibitory effect of agarwood oil on the growth of bacillus subtilis was found for the first time.

Objective Gastric cancer is the most common cancer in the world. In China, Patients with gastric cancer are mostly treated with platinum-based chemotherapy. Programmed cell death 4 (PDCD4) was found as an important proapoptosis recently, the aim of the present study was to investigate the role of PDCD4 reversed the apoptosis induced by cisplatin in gastric cancer cell. The study will provide the target marker for treatment and diagnosis of cisplatin resistance in gastric cancer.Methods Stable transfection with pCMV-PDCD4 vector into human cisplatin resistance gastric cancer cell line-SGC7901/DDP; the cells were divided into control group, over-expression group, control with cisplatin group, over-expression with cisplatin group for following experiments. Hoechst dying with immunofluorescence and flow cytometry were used to measure the cell apoptosis in vitro; Real-time PCR was used to detect the mRNA expression levels of PDCD4, and the protein levels of PDCD4, pAK, pGSK3β, BCL-2 and Bak were detected by Western blot. The cells were divided into vector group, PDCD4 group, PDCD4 with activator group for detect the level of PARP(C) by Western blot.Results Compared with control group, the Results of real-time PCR and western blot were showed the level of PDCD4 was augmented in over-expression group (also in the over-expression with cisplatin group), which was indicated stable transfection with PDCD4 was successful. Immunofluorescence (with hoechst dying) and flow cytometry demonstrated that PDCD4 facilitated cell apoptosis exposed to cisplatin. PDCD4 overexpression attenuated the protein levels of pAkt, pGSK3β and BCL-2, but increased the protein levels of BAK. Furthermore, incubation with SC-79 (the activator of Akt) reversed cell apoptosis induced by PDCD4.Conclusion Overexpression of PDCD4 promotes the apoptosis induced by cisplatin through pAKT/pGSK3β pathway, which is favorable to reverse cisplatin resistance in gastric cancer.

Objective: To compare the short-term and long-term outcomes between robotic-assisted and laparoscopic-assisted radical right hemicolectomy in patients with adenocarcinoma of the right colon. Methods: Retrospective review of a prospectively collected database identified 288 right colon cancer patients who underwent either robotic-assisted (n=57) or laparoscopic-assisted right hemicolectomy (n=231) between October 2014 and October 2020 at Department of Gastrointestinal Surgery, the Affiliated Hospital of Qingdao University. There were 161 males and 127 females, aging (60.3±12.8) years (range: 17 to 86 years). After propensity score matching as 1∶4 between robotic-assisted and laparoscopic-assisted right hemicolectomy, there were 56 cases in robotic group and 176 cases in laparoscipic group. Perioperative outcomes and overall survival were compared between the two groups using t test, Wilcoxon rank sum test, χ² test, Fisher exact test, Kaplan-Meier method and Log-rank test, respectively. Results: The total operative time was similar between the robotic and laparoscopic group ((206.9±60.7) minutes vs. (219.9±56.3) minutes, t=-1.477, P=0.141). Intraoperative bleeding was less in the robotic group (50 (20) ml vs. 50 (50) ml, Z=-4.591, P<0.01), while the number of lymph nodes retrieved was significantly higher (36.0±10.0 vs. 29.0±10.1, t=4.491, P<0.01). Patients in robotic group experienced significantly shorter hospital stay, shorter time to first flatus, and defecation (t: -2.888, -2.946, -2.328, all P<0.05). Moreover, the overall peri-operative complication rate was similar between robotic and laparoscopic group (17.9% vs. 22.7%, χ²=0.596,P=0.465). The 3-year overall survival were 92.9% and 87.9% respectively and the 3-year disease-free survival rates were 83.1% and 82.6% with no statistical significance between the robotic and laparoscopic group (P>0.05). Conclusions: Compared to laparoscopic-assisted right hemicolectomy, robot-assisted right hemicolectomy could improve some short-term clinical outcomes. The two procedures are both achieving comparable survival.
