Objective To study the anti-neuroglioma effect of methyl-mercuric chloride(MMC) by observing the morphological changes of apoptotic neuroglioma cells induced with MMC in rats with brain neuroglioma.Methods The rat models of neuroglioma were established,and divided into two groups.The rats in experimental group were lavaged with MMC 1 week after injected with C6 glioma cells,10 mg?kg-1every day,the rats in control group were treated with sodium chloride at the same dose.24 d after inoculation all rats were sacrificed except natural death,the brain tissues were obtained,and the pathohistological changes were observed under light microscope and transmission electron microscope.Results The macropathological result showed that the tumor volume in experimental group was smaller than that in control group.Under light microscope,in experimental group the growth density of C6 ghioma cells was lower than that in control group,and the apoptotic cells with smaller volume and karyopyknosis were found.The result of transmission electron microscope showed that in experimental group,the glioma cells had some changes such as karyopyknosis,chromoplasm margination,nuclear fragmentation and vacuolar degeneration and so on.Conclusion MMC has inhibitory effect on the proliferation of C6 glioma in rats in vivo,its mechanism may be related to inducing the apoptosis of neuroglioma cells.

Objective:The significant role of long non-coding RNAs (lncRNAs) in early diagnosis and predicting prognosis has been recognized in various cancers recently.However,the prognostic value of HOXA transcript at the distal tip (HOTTIP),a vital lncRNA in tumorigenesis,remains unclear.In this study,we evaluated its prognostic value by analyzing the correlation of HOTTIP expression with overall survival (OS),lymph node metastasis (LNM) and distant metastasis (DM) in different cancer types by meta-analysis.Methods:We performed a systematic search in PUBMED,MEDLINE,Web of Science and Cochrane Library update to November of 2016.A total of 604 patients from 6 studies were included in final analysis and went through a quantitative meta-analysis by Review manager 5.3.Results:We demonstrated that high expression of HOTTIP had a significant correlation with poor OS (hazard ratio [HR] =2.37,95％ confidence interval [CI] =1.81-3.10,p＜0.001),high LNM rate (odds ratio [OR]=2.29,95％CI=1.54-3.40,p＜0.001) as well as more DM occurrence (OR=3.30,95％CI=1.78-6.12,p＜0.001).Conclusion:Our results indicated that long non-coding RNA HOTTIP may serve as a potential prognostic biomarker in cancer progression.

For more than 40 years primary hepatocytes culture technique has been utilized extensively for assessing effects of drug on metabolizing enzymes (especially cytochromes P450), drug metabolism, drug-drug interactions, and the mechanisms of cytotoxicity and genotoxicity. Human derived primary hepatocytes reserve the metabolism function and enzyme activity of liver. Therefore, this technique has been widely used as a reliable and efficient tool in the drug and xenobiotics evaluation and screen in vitro. This review focuses on primary culture technique of hepatocytes and its application in drug metabolism and toxicology research and evaluation.

two-dimensional strain echocardiography can observe dynamic change of regional systolic function,combined with the two methods can more accurately assess the treatment results of coronary artery bypass surgery.

Objective To investigate the effect of mild hypothermia on glucose regulated protein 78 (GRP78) expression in hippocampus following transient cerebral ischemia-reperfusion (I/R) in aged rats.Methods One hundred and forty-four male aged Sprague-Dawley rats,weighing 450-550 g,were randomly divided into 3 groups (n=48 each): sham operation group (group S),I/R group and mild hypothermia group (group H).Global cerebral I/R was induced by 4-vessel occlusion method.Bilateral vertebral arteries were permanently occluded by cauterization,and bilateral carotid arteries were occluded for 5 min.The surface cooling was started immediately after reperfusion and maintained for 3 h.During surface cooling,the body temperature was maintained at 32-34 ℃(rectal).At 6,12,24 and 48 h of reperfusion,the expression of GRP78 was determined using immuno-histochemisty and Western blot,and the viable neurons in CA1 area were counted.Results The number of viable neurons was significantly smaller at each time point,and the expression of GRP78 was significantly higher at 6,12 and 24 h of reperfusion,while lower at 48 h of reperfusion in I/R group,and the number of viable neurons was significantly smaller,and the expression of GRP78 was significantly higher at each time point in group H than in group S (P＜ 0.05).The number of viable neurons was significantly larger at 12,24 and 48 h of reperfusion,and the expression of GRP78 was significantly higher at each time point in group H than in group I/R (P ＜ 0.05).Conclusion Mild hypothermia can further up-regulate GRP78 expression in hippocampus following transient cerebral I/R in aged rats,thus reducing endoplasmic reticulum stress and cerebral I/R injury.

OBJECTIVETo explore the clinical effects of transforaminal endoscopic spine system in surgical revision of lumbar vertebrae.

METHODSFrom January 2012 to October 2013,14 patients who needed reoperations of lumbar vertebrae were treated using transforaminal endoscopic spine system (TESSYS). There were 8 males and 6 males, aged from 27 to 84 years old with an average of (50.4 ± 18.9) years. Visual analogue scale (VAS) and Japanese Orthopaedic Association Scores (JOA) were compared before and after surgical revision. Macnab standard was used to assess the clinical effect.

RESULTSAll the patients were followed up from 6 to 27 months with the mean of 18 months. Preoperative VAS score was 6.79 ± 1.31, and in a week,3 months and 6 months after operation were 2.50 ± 1.29, 2.21 ± 1.53, 1.64 ± 1.08, respectively, which were all much lower (P < 0.01) than preoperative score. Preoperative JOA score was 12.43 ± 1.95, and the above corresponding postoperative JOA scores were 21.50 ± 3.78, 21.93 ± 4.55, 23.36 ± 4.33, respectively, which were all much higher than preoperative score (P < 0.01). According to the modified Macnab criteria, 5 patients got an excellent results, 7 good, 1 fair and 1 poor. The nerve root injury of L5 occurred in 1 case during paracentesis and no other complications were found.

CONCLUSIONSelecting the appropriate indications using TESSYS in surgical revision of lumbar vertebrae can successfully avoid the operation scar, reduce the surgical complications and obtain satisfactory clinical outcomes.

A high-performance liquid chromatography method of pre-column derivatization with 1-phenyl-3-methyl-5 -pyrazolone (PMP) has been established for determination of 6 kinds of monosaccharides simultaneously. A special Agilent HC-C18 column (4. 6 mm x 250 mm, 5 microm), optimized for the separation of PMP derivatives, was used at ambient temperature of 40 degrees C. The PMP derivatives elution was performed with a mixture of 0.1 mol x L(-1) phosphate buffer (pH 6. 8) and acetonitrile in a ratio of 84: 16 at a flow rate of 1 mL x min(-1), and UV absorbance of the effluent was monitored at 245 nm. The results showed that the polysaccharides from exopleura of Ginkgo biloba were acidic heteropolysaccharides mainly containing mannose, rhamnose, D-galacturonic acid, glucose, galactose, arabinose, with the molar ratio of 0.032: 0.14: 0.296: 0.403:0.106: 0.046.

Objective To explore the distribution rule of metastatic lymph node in nasopharyngeal carcinoma (NPC) by magnetic resonance imaging (MRI).Methods 315 histopathologically proved NPC patients were studied retrospectively.All patients had had their nasopharynx scanned by MRI with plain and contrast enhanced sequences.The distribution of lymph node was divided into six cervical levels plus retro- pharyngeal nodes(RN) according to RTOG guidelines proposed in 2003.Results 254 out of 315 patients (80.6%) had lymph node involvement,with 81 in the right neck alone,72 left neck alone,and 101 both necks;73 in RN alone,21 neck node alone,and 160 both necks and RN node.Skip metastasis was found in only 4 patients (1.6%).There was significant difference in BN metastasis between the primary tumor be- ing located merely on the superior/posterior wall and lateral wall (78% vs 49%,P＜0.01).The incidence of lymph node metastasis in T1,T2,T3 and T4 patients was 73.5%,91.2%,71.9%,73.5% (P＞0.05), respectively,without significant difference between early or advanced T stage in node distribution (P＞0.05).Conclusions The incidence of lymph node metastasis is high in nasopharyngeal carcinoma,with retropharyngeal node being the most commonly involved,but the incidence of skip metastasis is very low. There is no significant difference between T stage and the incidence of lymph node metastasis.So is the dis- tribution of metastatic node.
