Objective To survey gene expression profiles in nonlesional refractory temporal lobe epilepsy(TLE)and to further verify the difference of gene expression.thus to evaluate the possible molecular pathogenesis of this kind of epilepsy that can help to supply a new way for the diagnosis and treatment.Methods The TLE samples and control cases were studied by means of cDNA microarray consisting of 1 8 000 genes.Reverse transcription polymerase chain reaction(RT-PCR)Was performed to measure the expression alterations of SH3GL2.BTNN2A2 and KCNJ4 mRNA in temporal cortex samples from patients who had undergone temporal lobectomy surgery for intractable epilepsy.Tissue from 10 subjects who did not have epilepsy served as controls.Results The known genes differently expressed in those TLE samples involved immunity correlation factor genes,signal conduction genes,ion channel transportation genes;mitochondria function genes and SO on were identified.Among which.the expression of SH3GL2 mRNA Was significantly increased in epileptic brain(1.022±0.547)compared with the controls(0.446±0.171,t=-3.181).In TLE group(0.481±0.196),the expression of BTN2A2 mRNA was also significantly higher than that of control subjects(0.243±0.111,t=3.351).Compared with control group(O.795±0.112),the expression of KCNJ4 mRNA Was significantly decreased in TLE patients(0.438±0.178).Conclusions cDNA microarray is an efficient and high.throughout method to survey gene expression profiles in intractable temporal lobe epilepsy.The variation of those gene expressions might be a potential etiological agent for TLE that may offer a novel target for anticonvulsant therapy.

Objective To explore how to reasonably deploy the wounded and sick region on the medical evacuation ship.Methods Three models of the wounded and sick region were set up according to different demand.Simulated exercises were imitated and medical staff and experts selected reasonable models.Results Most medical staff and experts selected the model which deployed the wounded and sick region according to whether the condition of an injury should be treated.Conclusion It is scientific and reasonable that the wounded and sick region is deployed according to whether the condition of an injury should be treated.

Objective To evaluate the role of CT in the diagnosis of the primary carcinoma of the duodenum.Methods CT findings of 15 patients with primary carcinoma of the duodenum(12 adenocarcinoma,3 carcinoid)underwent surgical treatment or biopsy were reviewed.Results 9/12 of adenocarcinomas were shown as local soft tissues masses;6/12 of adenocarcinomas manifested as ductal wall irregular or circular thickening;3/12 of adenocarcinomas were shown as local soft tissues masses accompanied with deformation and constriction of duodenum.Cholangiectasis,metastasis of retroperitoneal lymph nodes and liver were also founded.CT cannot difference adenocarcinoma with carcinoid.After enhancement,the masses were manifested as mild or intermediate enhancement in the early stage and they did not show obviously enhancement in the delay or portal stage.Conclusion CT play an important role in both the localization and qualitative diagnosis of the primary carcinoma of duodenum,but it is difficult to difference adenocarcinoma with carcinoid.

Objective To observe the effect of microprismatic needle scalpel(MPNS) on headache induced by compression of greater occipital nerve or lesser occipital nerve.Methods 95 patients with headache induced by compression of occipital nerve were divided into the treatment group (50 cases, treated with MPNS) and control group (45 cases, treated with carbamazepine).Results In the treatment group, 42 cases were cured, 6 cases were effective, 2 cases were ineffective; while, those in the control group were 16 cases, 21 cases and 8 cases respectively. There was a significant difference between two groups ( P<0.01).Conclusion MPNS has an obvious effect on headache induced by compression of occipital nerves.

Objective To investigate the clinical effect of porcelain fused for metal crown restoration after root canal therapy.Methods Totally 90 patients with pulpitis or periapical periodontitis from December 2013 to December 2015 had their clinical data analyzed,who underwent root canal therapy and were divided equally into an observation group and a control group.The observation group took porcelain endocrowns repair and the control group applied ceramic crown.The two groups were compared on the restoration integrity,edge sealing,residual rate,gum,food impaction and color 3 months,6 months and 1 a after treatment.Results The observation group behaved significantly better than the control group in the edge sealing and restoration integrity (P＜0.05).There were significant differences between the residual rates,gum and food impaction in the two groups (P＜0.05).Conclusion Porcelain endocrowns repair gains advantages over ceramic crown repair in edge sealing,integrity,gum,food impaction and color after root canal therapy,though its long-term effect needs further investigation.

OBJECTIVEThe aim of this study was to investigate the effect of 5-aza-2'-deoxycytidine (5-Aza-dc), a methylation inhibitor, on cisplatin-resistance in non-small cell lung cancer cell line A549/DDP and to explore its possible mechanism.

METHODSMTT assay was used to test the cytotoxicity of 5-Aza-dc on A549/DDP cells, and the IC(50) and cisplatin resistance index of A540/DDP cells at 48 hours after 5-Aza-dc (0 µmol/L, 20 µmol/L, 40 µmol/L) treatment at different concentrations. MSP, fluorescence quantitative RT-PCR (real-time RT-PCR) and Western blot were used to detect the hMLH1 methylation status, mRNA and protein expressions, respectively.

RESULTSThe IC(50) value of cisplatin in A549/DDP cells was 30.15 ± 0.76 µmol/L. The MTT assay results demonstrated that during the 5-Aza-dc treatment for 48 hours, the dose of 20 µmol/L was non-toxic and 40 µmol/L was low-toxic. 5-Aza-dc at those two doses reduced IC(50) value of cisplatin to 16.54 ± 0.35 µmol/L (RI = 1.82) and 6.82 ± 0.16 µmol/L (RI = 4.42), respectively. MSP, real-time RT-PCR and Western blot showed that 5-Aza-dc at non-toxic and low-toxic doses removed the partial hMLH1-hypermethylation, and up-regulated hMLH1 mRNA and protein expressions.

CONCLUSIONSLow dose 5-Aza-dc can partially reverse the cisplatin-resistance in A549/DDP cells, which may be achieved through removal of hMLH1 hypermethylation and increased expression of hMLH1 gene. 5-Aza-dc may have a role in increasing the efficacy of chemotherapy for patients whose tumors are lack of hMLH1 expression because of hMLH1 promoter hypermethylation.

By retrieving the clinical research literature of treatment functional dyspepsia by traditional Chinese medicine (TCM) from January 2004 to December 2014 based on China National Knowledge Internet (CNKI), we would establish a TCM decoction database for treating functional dyspepsia in this study. One hundred and sixty-four literature were included, involving 159 prescriptions, 377 medicines, in a total of 1 990 herbs. These herbs can be divided into 18 categories according to the effectiveness; and qi-regulating herbs, blood circulation herbs, and antipyretic herbs ranked top three ones according to the frequency of usage of the herbs, whose medicine usage frequency accounted for 51.81%. Usage frequency of 16 herbs was over 30, and Atractylodes, Radix, Poriaranked top three according to the usage frequency. Medicinal properties were divided into 9 kinds according to the frequency statistics, and the top three were warm, flat, and cold. Taste frequency statistics were classifiedinto 9 kinds, and the top three were acrid, sweet, and bitter. In frequency statistics of the meridian tropism of herbs, it was classifiedinto 11 kinds, and the top three were spleen, stomach, lung. The analysis can provide a reference for treatment and study of TCM of functional dyspepsia.
