Long noncoding RNAs( lncRNAs) are transcribed RNA molecules more than 200 nt in length, without protein coding capacity.In recent years,emerging evidence has shown that lncRNAs act as key regulators of multiple cancers.LncRNA is possible to be a new focus for cancer treatment.Until now,only a few papers about lncRNA had been reported in head neck tumor.In this review,we report the development of lncRNA in head neck tumorbased on the latest studies.

OBJECTIVE:To know the utilization of essential medicines in outpatient department of Sichuan Shuangliu Maternal and Child-care Hospital,and provide reference for the rational drug use. METHODS:The types,names,formulations,consump-tion sum and utilization of essential medicines in the outpatient department of the hospital from 2012 to 2013 were statistically ana-lyzed and ranked. The affordability of top 10 drugs in the list of DDDs was evaluated. RESULTS:Compared with 2012,the con-sumption sum proportion of essential medicines in the outpatient department of the hospital in 2013 was increased by 5.80%. The top 10 essential medicines in the list of consumption sum were mainly anti-microbial drugs,anti-anemia drugs and Chinese patent medicines. The relative daily wages of Kangfuxin solution and Amoxillin and clavulanate potassium tablets were respectively 2.12 d and 2.05 d,with poor affordability,and in 2012,they ranked the 5th and 8th in the list of DDDs;the relative daily wages of Xiao-er changweikang granule and Xingpi yanger granule were respectively 2.28 d and 2.14 d,with poor affordability,and in 2013, they ranked the 8th and 10th in the list of DDDs. CONCLUSIONS:The utilization of essential medicines in the hospital is basical-ly good,with a trend of increasing. However,the similar essential medicines with lower prices should be considered when essential medicines are used in the clinic.

To observe the effect of Weiyanxiao Granule (WG) in counteracting experimental gastric ulcer,acute lesion of gastric mucosa and to investigate its anti-inflammation and analgesic actions.Acute gastric ulcer models induced by stress or indomethacin, chronic gastric ulcer models induced by acetic acid and models with acute lesion of gastric mucosa induced by hydrochloride-ethanol or 0.2 mol?L -1 sodium hydroxide were used to observe the effect of WG in counteracting experimental gastric ulcer and acute lesion of gastric mucosa. Anti-inflammation action of WG was observed on mouse models with auricular swelling induced by dimethylbenzene, rat models with pedal swelling induced by white egg and rat models with granuloma induced by embedding tampon. Hot plate method and body-torsion test were used to observe the analgesic action of WG. As compared with the control group, WG 12.3?g?kg -1 and 24.6?g?kg -1 could decrease the ulcer index in rats with acute gastric ulcer (P

Objective The concentration of NE and TNF-α was detected for elucidating the change of them in sera and bronchoalveolar lavage fluid (BALF) of rabbits with acute lung injury interposed by XueBiJing therapy in underwater explosion.Methods Underwater explosion decive was applied to cause acute lung injury of rabbits.The 20 rabbits were randomly divided into two groups which were injury group and XueBiJing therapy group,respectively.The concentration of NE and TNF-α in sera and BALF were detected by ELISA method in 24 hours after bursting.Results The concentration of TNF-α in sera (353.30±166.86 ng/L) of rabbits in therapy group were significantly lower than those in injury group (552.30± 169.64 ng/L;t=2.645,P =0.016).The concentration of NE in sera (63.40 ± 36.09 ng/ml) were lower than that of rabbits in injury group (97.60 ± 36.20 ng/ml;t=2.116,P=0.049).At the same time the concentration of NE in BALF (102.10± 9.50 ng/ml) of rabbits in therapy group were significantly lower than those in injury group (136.70± 13.60 ng/ml;t=6.593,P=0.000).Conclusion The expression of TNF-α in sera and NE in sera and BALF in rabbits with acute lung injury interposed by XueBiJing in underwater explosion were lower than those of injury group.

Aim Our previous study has found that ur-solic acid( UA) increased intracellular reactive oxygen species ( ROS ) production and adenosine monophos-phate-activated protein kinase ( AMPK ) phosphoryla-tion, inhibited signal transducer and activator of tran-scription 3 ( STAT3 ) phosphorylation and cyclooxygen-ase-2 ( COX-2 ) expression in gastric cancer cells . However , the molecular mechanism by which UA in-hibits COX-2 expression in gastric cancer cells has not been fully clarified .In this study we aimed to further clarify the signal transduction pathways involved in the UA-mediated inhibition of COX-2 expression in gastric cancer cells .Methods Human gastric cancer cell lines SGC-7901 and MKN-45 were routinely cultured in RPMI-1640 medium supplemented with 10% heat-in-activated fetal calf serum .Sub-confluent cell cultures were pre-treated with antioxidant N-acetylcysteine ( NAC) , AMPK activator 5-amino-4-imida-zolecarbox-amide-riboside ( AICAR ) , AMPK inhibitor compound C, or STAT3 inhibitor WP1066 and then treated with or without UA for 24 h.The expression of AMPK and phosphorylated AMPK ( p-AMPK ) , STAT3 and phos-phorylated STAT3 ( p-STAT3 ) , as well as COX-2 was detected by Western blot analysis .Results Antioxi-dant NAC and AMPK inhibitor compound C blocked UA-induced inhibition of STAT 3 phosphorylation and down-regulation of COX-2 expression in gastric cancer cells.Both AMPK activator AICAR and UA inhibited STAT3 phosphorylation and COX-2 expression; the combination of two drugs resulted in further reduction . STAT3 inhibitor WP1066 did not affect UA-induced AMPK phosphorylation , whereas it inhibited STAT3 phosphorylation and COX-2 expression .The inhibitory effects on the STAT3 phosphorylation and COX-2 ex-pression were significantly enhanced when SGC-7901 and MKN-45 cells were treated simultaneously with WP1066 plus UA.Conclusion UA inhibits COX-2 expression in gastric cancer cells , which may be medi-ated through ROS/AMPK/STAT3 signal transduction pathway .

Objective To evaluate the relationship of preoperative neutrophil-lymphocyte ratio (NLR) with clinicopathological features and prognosis of colorectal cancer in middle-aged and elderly patients.Methods A retrospective analysis was performed in 212 patients with colorectal cancer in the First Affiliated Hospital of Nanjing Medical University from January 2011 to June 2013.All patients were divided into middle-aged group (46-65 year old,n=130) and old-aged group (66-89 year old,n=82),The optimal cut-off point of NLR was identified by the area under receiver operating characteristic curve,while NLR ＞ 3.13 and NLR≤3.13 were classified as high and low NLR group.The clinicopathological features and prognosis between the two groups were compared.Results There was no difference in gender,tumor growth site,depth of invasion,tumor embolus,lymphatic metastasis,distant metastasis,TNM stage between low and high NLR group (allP＞ 0.05).However,the difference between high NLR group and low NLR group in old-aged group with diabetes mellitus was statistically significant (P＜0.05).The 1-,2-,and 3-year survival rate of the overall 212 patients were 96.2％ (204/212),87.7％ (186/212) and 74.5％ (158/212) In middle-aged group,the 1-,2-,and 3-year survival rates were 98.8％ (85/86),90.7％ (78/86) and 84.9％ (73/86) respectively in low NLR group,but 95.5％ (42/44),84.1％ (37/44) and 72.7％ (32/44) respectively in high NLR group,(allP＜0.05).In old-aged group,the 1-,2-,and 3-year survival rates were 95.7％ (44/46),89.1％ (41/46) and 73.9％ (34/46) respectively in low NLR group,but 91.7％ (33/ 36),83.3％ (30/36) and 52.8％ (19/36) respectively in high NLR group (all P＜0.05).Cox regression showed that TNM stage and NLR were independent risk factors for the prognosis of the middle-aged and elderly patients with colorectal cancer (P＜0.05 or P＜0.01).Conclusions Preoperative NLR ＞ 3.13 suggest that the prognosis is poor in middle-aged and elderly patients with colorectal cancer.

Objective The expression of TNF-α was detected in sera of rabbits treated by ulinastatin with acute lung injury in duced by underwater explosion.Methods Rabbits were randomly divided into two groups such as the injured group and ulinastatin therapy group.Established underwater explosion device was used to cause acute lung injury in rabbits.TNF-α in sera of the rabbits were measured by ELISA at 4,12 and 24 hours after the explosion.The SPSS17.0 software was used to analyze the data and P＜0.05 was considered to be significant.Results There was no significant difference between the concentrations of TNF-α in the sera of rabbits in the injure group (538.20±201.43 ng/L) and that of in the ulinastatin group (386.90± 109.22 ng/L,t=2.088,P=0.051) at 4 hours after burst.However,there was evidently decreased in the level of TNF-α in the ulinastatin group (400.60 ± 78.98 ng/L) compared with the injury group (573.80 ± 178.24 ng/L,t =2.809,P =0.012) at 12 hours after burst.Moreover and TNF-α in the ulinastatin group (356.10 ± 130.99 ng/L) was also decreased compared to the injure group (552.30± 169.64 ng/L,t=2.895,P=0.010) at 24 hours after burst.Conclusion The TNF-α expression in sera of the rabbits in ulinastatin group were dramatically decreased than thai of in injury group at 12 hours after burst,which may be benefit to rabbits with acute lung injury induced by underwater explosion.

Objective To investigate the value of detecting methylated SEPT9 gene (mSEPT9) in serum and stool in screening colorectal cancer in elderly people.Methods Subjects were divided into three groups, the colorectal cancer group (n=82), the colorectal polyps group (n=80) and the healthy control group (n=100).Real-time quantitative polymerase chain reaction (PCR) was used to detect mSEPT9 in peripheral blood and feces.The relationship between mSEPT9 and clinical and pathological characteristics of colorectal cancer was analyzed.The agreement between serum and stool results was analyzed.Results The positive rate of serum mSEPT9 was 73.2％ in the colorectal cancer group, 6.3％ in the colorectal polyps group and 4.0％ in the healthy control group, with statistical significance between the colorectal cancer group and the other two groups (P＜0.01).The sensitivity and specificity for plasma mSEPT9 detection in screening colorectal cancer were 73.2 ％ and 95.6％, respectively.The positive rate was higher in patients with tumor maximum diameter over 3.0 cm, invasion of the entire serosa layer, lower differentiation or advanced clinical staging (P＜0.05).The detection results of plasma mSEPT9 were in complete agreement with those of stool mSEPT9 from the same patients.Conclusions The expression of mSEPT9 is high in elderly patients with colorectal cancer and has a high sensitivity and specificity for PCR detection.Complete agreement can be seen in results from plasma and feces.Detecting mSEPT9 can be a valuable approach to screening colorectal cancer in the elderly.

[ ABSTRACT] AIM:To investigate whether the increase in PTEN expression is related to apoptosis, and whether it is regulated by reactive oxygen species( ROS) .METHODS: The rat islet cells were divided into constant low glucose group ( group L) , constant high glucose group ( group H) , glucose fluctuation group ( group F) , low glucose after high glucose group (group HL) and low glucose after fluctuation group (group FL).The ROS level, apoptotic rate, intracellu-lar calcium, insulin release and PTEN protein expression were analyzed.RESULTS:Compared with groups H and L, the insulin secretion decreased, and intracellular calcium, ROS level, PTEN protein expression and apoptotic rate increased in group F ( P<0.05) .Compared with group H, the intracellular calcium, ROS level, PTEN protein expression and apoptot-ic rate in group HL decreased, but were still higher than those in group L (P<0.05).Compared with group F, the intra-cellular calcium, ROS level, PTEN protein expression and apoptotic rate in group FL decreased, but were still higher than those in group L (P<0.05).CONCLUSION:Glucose fluctuation can cause the apoptosis of islet cells more easily than constant high glucose.This may be related to the change of intracellular calcium and increase in oxidative stress which pro-motes PTEN expression.The recovery of glucose level to some extent relieves oxidative stress, decrease PTEN expression and reduce cell damage.

To find the identification method of seeds from different locations, we analyzed the SDS-PAGE electrophoretogram of Magnolia officinalis seeds from 5 different locations of Enshi district, Hubei province, the genuine producing area of M. officinalis, and compared band numbers, band intensity and protein molecular weight of different locations. The result showed that there were significant differences among seeds from different locations. 9 bands with the molecular weight about 80.34, 63.07, 56.48, 51.32, 40.64, 25.18, 22.63, 21.70, 18.14 kDa were involved in all seeds electrophoretograms and could be as standard bands of M. officinalis seeds. Seeds from Badong county, Jianshi county and Enshi city had their own special bands which were very different from other locations. So this electrophresis method can be applied to identify different locations of M. officinalis seeds.
