Long non-coding RNAs (lncRNAs) are non-coding RNAs that have transcript lengths exceeding 200 bp and do not have the capacity for protein coding because of having no open reading frame. In the human genome, lncRNAs play important regulato-ry roles in the process of epigenetic, transcription and post-transcription, so they have become the focus of research followed by mi-croRNAs. The abnormal expression of lncRNAs in cancer usually represents different functions, such as the function of oncogenes or tumor suppressor genes, which promote or inhibit tumor growth. Lung cancer is a common malignant tumor with a five-year survival rate of 17%. Previous literature shows that MALAT1, H19, lincRNA p21, UCA1, and BC200 are closely related to the development of lung cancer. They could promote cancer growth, invasion and metastasis, apoptosis and induce drug resistance, and so on. This review aims to provide assistance in the diagnosis, treatment, and prognosis of lung cancer by clarifying the functions and mechanisms of ln-cRNAs.

BACKGROUND:Animal experiments have repeatedly verified that umbilical cord stem celltransplantation can improve the rotational behavior of rats with Parkinson’s disease, with lower immune rejection response.
OBJECTIVE:To evaluate the therapeutic effects of human umbilical cord mesenchymal stem celltransplantation in the treatment of Parkinson’s disease using the Unified Parkinson’s Disease Rating Scale.
METHODS:Fifteen patients with Parkinson’s disease were enrol ed, including 8 males and 7 females, aged 52-76 years. Hoehn&Yahr staging was 3-5. After informed consent was obtained from puerperae and the procedure was approved by the hospital ethics committee, ful-term maternal umbilical cord was aseptical y col ected, to culture umbilical cord mesenchymal stem cells. Al patients were hospitalized, and treated with human umbilical cord mesenchymal stem celltransplantation via carotid artery puncture. Neurological function of patients was assessed using a comprehensive rating scale for Parkinson’s disease before and 1 month after cells transplantation. Higher score indicated more severe neurological deficits.
RESULTS AND CONCLUSION:Fifteen patients entered the result analysis. Compared with before transplantation, 15 patients showed significantly lowered scores on the Unified Parkinson’s Disease Rating Scale at 1 month after transplantation (P<0.05). The improvement was mainly concentrated in the tremor and rigidity, but bradykinesia and unstable position were not improved. Graft versus host disease did not occur in al 15 cases. These findings indicate that umbilical cord blood mesenchymal stem celltransplantation for treating Parkinson’s disease has obvious curative effects and significantly improves neurological functions.

Objective To evaluate the value of MSCT scores on surgery method selection and its difficulty estimation for hepatic cystic echinococcosis. Methods Based on the CT features of hepatic cystic echinococcosis ( HCE), an integral system including 7 items wasestablished. Images of preoperative CT examination performed on 71 cases of hepatic cystic echnococcosis were retrospectively analyzed by the integral system and compared with actual surgical. Total 93 cystic lesions were divided into 3 groups based on CT scores: Group A suitable for total cystectom (0 to 5 score), Group B suitable for subtotal cystectom (6 to 10 score), and Group C suitable forendocystectomy ( ≥11 scores, or4 score in one item). Spearman rank correlation was used to analyze the relationship between WHO classification of cystic echinococcosis and actual surgery methods, the relationship between operation mode forecasted by CT scores and actual surgery methods, the relationship between vessel scores of cyst and actual surgery methods, and that between biliary score of cyst and actual surgery methods. Fisher exact test and Chi-square test were used to evaluate the incidence of residual cavity in patients with different biliary scores. Results Thirty nine cysts got 0 to 5 scores, 45 cysts got 6 to 10 scores and 9 cysts got more than 10 scores. Total cystectom was performed on 30 cysts, subtotal cystectomy on 40 cysts and performed endocystectomy on 23 cysts, actually. Actual operation methods were correlated with that predicated by CT scores ( r = 0. 741, P ＜ 0. 01 ), and with vessels score and biliary score (r = 0. 587,0. 327 respectively,P ＜ 0. 01 ). The higher the biliary score, the higher the incidence of postoperative biliary tract complications. Conclusions Preoperative CT scoring was an easy and objective way to accurately predict the surgery methods and its difficulty for hepatic cystic cnechnococosis.

Objective To explore the expressions of interleukin (IL)-17A and its receptor IL-17RA in different degrees of malignant gliomas. Methods Fifty patients with glioma were collected in this study. Accordance to the World Health Organization Classification System, patients were classified by malignancy grade, including gradeⅠ(n=12), gradeⅡ(n=18), gradeⅢ(n=13) and gradeⅣ(n=7). The glioma tissue and peripheral blood samples of patients were obtained for detecting the expression levels of IL-17A and IL-17RA mRNA by using immunohistochemistry, quantitative real-time PCR. Western blot assay was used to detect expressions of IL- 17A and IL- 17RA in both the macroscopic (immunohistochemistry) and molecular levels (mRNA and protein). Results Immunohistochemical staining showed that the expression levels of IL-17A and its receptor IL-17RA increased with the increase of the malignant degree of gliomas. The mRNA levels of IL-17A and IL-17RA receptors in peripheral blood were up-regulated with the increasing malignancy grade of glioma (F=8.96, P<0.05;F=10.34, P<0.05). The mRNA levels of IL-17A and IL-17RA in glioma tissues were up-regulated with the increasing malignancy grade of glioma (F=11.21, P<0.05;F=14.11, P<0.05). The protein levels of IL-17A and IL-17RA in peripheral blood and glioma tissues were also up-regulated with the increasing malignancy grade of glioma (in peripheral blood:F=9.90, P<0.05;F=11.80, P<0.05;and in gliomas tissues:F=8.15, P<0.05;F=14.46, P<0.05). Conclusion The expressions of IL-17A and IL-17RA receptor are positively correlated with malignancy grade of glioma. These results provide some reference for clinical diagnosis of malignant gliomas.

AIM: To explore the effects of cellular signal transduction pathways of heme oxygenase-1(HO-1)-carbon monoxide (CO)-cyclic GMP (cGMP) and nitric oxide synthase (NOS)-nitric oxide (NO)-cGMP on cholecystokinin octapeptide (CCK-8) reversed vascular hyporeactivity in endotoxemic rats. METHODS: According to the treatments given in vivo , rats were devided into four groups: control; lipopolysaccharide (LPS); CCK and CCK+LPS. Using isolated vascular ring tension detecting technique, thoracic aortic rings (TARs) were prepared and accumulation of contractive responses to phenylephrine (PE) were measured under which the TARs were incubated with Hemin (He, donor of CO), Zinc-protoporphyrin-IX (ZnPP-IX, selective inhibitor of HO-1), L-arginine (L-Arg, substrate of NOS), aminoguanidine (AG, selective inhibitor of iNOS), N ?-nitro-L-arginine (L-NNA, inhibitor of NOS) or methylene blue (MB, inhibitor of guanylyl cyclase), respectively. RESULTS: CCK-8 alone did not affect vascular tension. Injection of LPS induced the hyporeactivity of the TARs and was reversed by pretreatment of CCK-8. In LPS and CCK+LPS groups, the hyporeactivity was partly reversed by incubation of TARs with ZnPP-IX or AG, and restored to normal by incubation of TARs with L-NNA or MB. Incubation of TARs with He or L-Arg showed to make the vascular hyporeactivity worse in different degree. CONCLUSIONS: CCK-8 alone did not affect the activity of HO-1 and iNOS but influenced the activity of these enzymes induced by LPS, which lead to reduced CO/NO production, decreased the content of cGMP and plays its important role in reversing vascular hyporeactivity in endotoxemic rats.

Objective To detect the levels of anti-gliadin IgA and anti-gliadin IgG antibodies in the plasma of the patients with schizophrenia, and to investigate the association between schizophrenia and anti-gliadin IgA, IgG bodies in a Chinese Han population, and to clarify the effect of gliadin on the occurrence of schizophrenia.Methods The plasma samples were collected from 428 patients with schizophrenia and 555 cases of normal control subjects in a Chinese Han population.The gliadin antibodies in plasma,including IgA and IgG,were tested using a native anti-gliadin ELISA test kit.The positive rates of plasma anti-gliadin IgA,and anti-gliadin IgG were tested by Chi-square test between the patients with schizophrenia and control subj ects. The differences of the levels of anti-gliadin IgA and anti-gliadin IgG were tested by Mann-Whitney U test between the patients with schizophrenia and control subjects.Results Compared with normal control group,the anti-gliadin IgA level and the positive rate of plasma anti-gliadin IgA in patient group were increased significantly(P<0.01),but there were no significant differences of the positive rate and the level of anti-gliadin IgG in plasma between patient and control groups (P>0.05).The anti-gliadin IgA levels in the patients with delusion of observation,delusion of being revealed,delusion of persecution, delusion of j ealousy, delusion of grandeur, incoherence of thinking, illogic thought, bizarre behavior,aggressive behavior,hallucination-delusion syndrome,poverty of thought,emotional blunting/apathy and aboulia were higher than that of the normal controls (P<0.05);the anti-gliadin IgG levels in the patients with delusion of being revealed and delusion of grandeur were higher than that of the normal controls (P<0.05 ). Conclusion Gliadin is associated with the onset of schizophrenia in Chinese Han population, and the plasma antibodies of gliadin maybe play an important rale in the onset of schizophrenia.

Objective To discuss the feasibility of neuroendoscopic third ventriculostomy for chronic posttraumatic hydrocephalus (PTH).Methods Nineteen cases of chronic PTH treated with neuroendoscopic third ventriculostomy between October 2010 and October 2014 were analyzed retrospectively.There were 13 males and 6 females, aged 11-57 years (mean, 36.3 years).Trauma resulted from traffic accidents in 14 cases, falls in 4 cases and blunt object hitting in 1 case.Of the 19 cases analyzed, 5 had Glasgow Coma Scale (GCS) score of 13-15, 5 had score of 9-12 and 9 had score of 5-8 at admission.Results of operation were assessed with the Canada multicenter evaluation criteria.Prognosis was analyzed with the Glasgow Outcome Scale (GOS).Results All cases were followed up for mean 13.6 months (range, 6-26 months).Improvement of symptoms was achieved in 17 cases, but was not seen in 2 cases.Of the 2 cases, one required ventriculoperitoneal shunt two weeks after ineffective ventriculostomy, and one required second ventriculostomy one month after the presence of stoma blockage.No serious complications occurred.At follow-up, 9 cases had GOS score of 5, 8 cases had score of 4 and 2 cases had score of 3.Conclusions Neuroendoscopic third ventriculostomy is in line with the physical characteristics in cerebrospinal fluid circulation, which implies no shunt implantation, less operative trauma and less complications.The procedure is an effective approach for chronic PTH.

Objective To analyze the MSCT imaging of vascular and biliary ducts affected by hepatic cystic enchionococcosis disease(HCD),and to evaluate the 3D image reconstruction of MSCT.Methods Forty four cases with HCD confirmed by radical surgery were collected in this study.All cases underwent multi-phase scanning with 64-slices CT,and 3D image reconstruction of hepatic vessels was performed.Three cases suspected of bile duct complications were examined with negative CT cholangiography.All the imaging data were acquired before surgery.The spatial relationships between the cysts and the neighbor vessels and(or)bile ducts were compared with the findings during operation,then consistency was tested.Results Altogether 46 lesions were detected by MSCT before surgery.All lesions were found and diagnosed correctly,including 3 lesions rupturing into biliary duct Compared with surgery findings,the spatial relationships between lesions and the vessels were entirely consistent in first grade portal vein(14 cases)and inferior macular vein(18 cases).The Kappa values were 0.8805,0.6087,0.7751,0.7392 for first grade hepatic artery,second grade hepatic artery,second grade portal vein and hepatic vein.The relationships between bile ducts and lesions also matched in 3 bile-duct fistula cases.Conclusions MSCT with its 3D technique showed a high accuracy in the assessment of spatial relationship between vessels,biliary duct and lesions.It provides comprehensive imaging information for surgery.

To explore the mechanism of the absorption enhancement of Angelica dahurica extract (Ade), the absorption mechanism of baicalin in the Scutcllaria water extraction as well as the effect of Angelica dahurica extract on absorption of baicalin were investigated. In order to determine the main absorption site, everted intestinal sac model was used to study the effect of Angelica dahurica extract on the absorption of baicalin at duodenum, jejunum, ileum and colon. In situ single pass intestinal perfusion model was performed to study the absorption of various concentrations of baicalin and the effect of Angelica dahurica extract on the absorption of baicalin at the main absorption site. To authenticate the consequence of perfusion by getting the blood from the hepatic portal vein and determine the concentration of the baicalin in the blood. The result showed that baicalin could be absorbed at all of the four intestinal segments with increasing absorption amount per unit as follows: ileum > colon > jejunum > duodenum. The absorption ofbaicalin in the duodenum significantly increased with Angelica dahurica extract, thus, duodenum was chosen to be the studying site. Apparent permeability values (Papp) and absorption rate constant (Ka) of baicalin in the duodenum increased gradually with higher concentrations. When the concentration of baicalin rises to a certain degree, the absorption increase had a saturable process, the absorption of baicalin may be an active transportation. Baicalin may be not a substrate of P-gp as verapamil which had not significantly affected the Papp and Ka of baicalin. The absorption of baicalin in the duodenum significantly increased (P < 0.01) in the two models with Angelica dahurica extract and the concentration of baicalin in the blood from the hepatic portal vein showed that the Angelica dahurica extract can increase the absorption of baicalin.

Objective To study the effect of glutamate on the expression of vascular endothelial growth factor (VEGF) mRNA and protein in cultured rat astrocytes. Methods Cultured rat astrocytes were randomly divided into 6 groups: control group (C), glutamate group (G), QA group (Q), DCG-IV group (D), L-AP4 group (L) and glutanmte-FMCPG gronp (G+M). Cells were cultured under nomoxic condition (95% air, 5% CO2). RT-PCR and ELISA methods were used to detect the expression of VEGF mRNA and protein in cultured astrocytes, respectively. G+ M group was preincubated with lmM MCPG for 30 min prior to the stimulation with glutamate. There were 7 time points at 0,4,8,12,16,24 and 48 h in each group except G+M group. Results The expression of VEGF mRNA and protein did not differ significantly among D group, L group and C group. Different from that in C group, the expression of VEGF mRNA and protein could be enhanced both in a dose-dependent and time-dependent manner in G group and Q group. Meanwhile, the enhanced expression of VEGF mRNA and protein in G group was completely suppressed by MCPG after 24 h. Conclusion Glutamate can increase the expression of VEGF mRNA and protein in cultured astrocytes, which may be due to the activation of group I metabotropic glutamate receptors in astrocytes.
