Objective To study the different biomechanics surgical effects of posterolateral fusion , the transverse fusion and the interbody fusion. Method Scan CT was followed with preprocess of images. The Mimics , HyperMesh and Geomagic Studio Reverse engineering softwares were used to establish the modles of lumbar fusion , then the finite element computation was conducted by using the Abaqus finite element software. Result The EF of each lumbar modle was established , the EF of the interbody fusionwas rised evidently. After the fusion , the stress of the adjacent lumbar were also rised, among them the stress of the upper adjacent segment in tnterbody fusion was the most in extension and rotation , with statistical significance ( P < 0 . 05 ) . In the antexion the stress of the transverse fusion was the most, and the new type of posterolateral fusion least, three of them all hadstatistical significance (P<0.05). In the lateral flexion, they had no statistical significance (P>0.05). About the under adjacent sengment, in the extension and antexion, the stress of the interbody fusion was the most, and the new type of posterolateral fusion was the least, the three of them all haved statistical significance (P<0.05, respectively). In the rotation and lateral flexion, with no statistical significance (P>0.05). Conclusion After the fusion, the EF of the lumbar and the stress of the lumbar disc are all established, the interbody fusion is most, while the others are lower.

The vast majority of vertebral compression fractures are caused by osteoporosis and vertebral tumor,which lead to the pain of a fracture and intervertebral height lost.In recent 20 years,the use of percutaneous vertebroplasty and percutaneous kyphoplasty,a kind of minimally invasive surgery method intended for the vertebral compression fractures,are rising up for patients with vertebral compression fractures,which can quickly relieve patients' pain and restore injured vertebral deformities.Percutaneous vertebroplasty injects bone cement into fractures through a small incision.However,percutaneous kyphoplasty injects a balloon into a fracture to make a cavity by expending and shrinking,which is filled with filler material,and then removes the balloon,and injects bone cement.This article mainly reviews development,curative effect and safety,clinical application and future aspects.of the percutaneous vertebroplasty and percutaneous kyphoplasty.

Objective:To investigate the clinical significance of Her2 pathological expression in the breast and gastric cancer patients for providing a reference for cancer prevention. Methods: Selected surgical resection specimens of 60 diagnosed in advanced gastric cancer and 60 diagnosed with advanced breast cancer from March 2009 to May 2014 in our hospital,all specimens were given the Her2 pathological expression of immunohistochemical analysis and investigation the clinical and pathological data. Results: The Her2 positive expression rates in the breast cancer and gastric cancer specimens were 40. 0% and 36. 7%,respectively that compared to no significant difference (P>0. 05). The Her2 expression was not related to the cancer patient’s age,histological type,and there were sig-nificantly correlated to the TNM stage and lymph node metastasis ( P<0. 05 ) . Spearman correlation analysis showed that Her2 expression in the breast cancer and gastric cancer were significant positive correlation to the Survivin, Bcl-2 expression ( P<0. 05 ) . Conclusion:Breast cancer and gastric cancer patients have shown high pathological expression of Her2,and are related to the TNM stage and lymph node metastasis, it may be through inhibited the apoptosis regulating proteins involved in the pathogenesis and metastasis of tumors.

Objective The aim of this study was to evaluate the prognosis of resection followed by chemotherapy compared with chemoradiotherapy for limited-stage small cell lung cancer .Methods The clinical data of 230 limited-stage small cell lung cancer patients with curative treatment between January 2006 and December 2011 were retrospectively analyzed .All patients divided to two group: the resection plus chemotherapy ( S +C ) and chemoradiotherapy ( R +C ) .And the prognostic factors were further analyzed with limited stage small cell lung cancer .The Kaplan-Meier method was used for the survival analysis.Results The overall survival rates of 1-year, 3-year and 5-year were 87.0%, 38.9%, 25.4%, respectively and the media survival time ( MST) 26.0 months.When patients were stratified by clinical stageⅠ+Ⅱ, the 1-year , 3-year and 5-year overall survival rates of S +C group and R +C group were 92.6%, 63.2%, 47.3%and 76.2%, 42.9%, 30.6%, respectively (χ2 =7.851, P<0.05), while those were 88.5%, 26.9%, 10.6% and 86.0%, 25.1%, 25.1%, respectively in stage ⅢA with no significant difference ( P >0.05).In univariate analysis, tumor location, tumor stage, lymph node metastasis, TNM stage, the cycle of chemotherapy , treatment modalities were significantly associated with survival ( RR=1.735, P<0.05).The multivariate analysis only showed TNM stage were independent factors of prognosis .Conclusions The results suggested that resection plus chemotherapy could improve the prognosis of early-stage(stageⅠ+Ⅱ) small cell lung cancer, but patients in ⅢA stage should received the definitive chemoradiotherapy .The TNM stage was still the independent factor of prognosis .

Objective To compare dose-volume parameters for local failure in esophageal cancers treated by there-dimensional conformal radiotherapy (3 D-CRT) or intensity modulated radiotherapy (IMRT) with different target regions.Methods A total of 244 patients with esophageal cancer (including 127 patients with local recurrence and 117 without recurrence) underwent radical 3D-CRT and IMRT were enrolled in this study.Data including dose-volume parameters and clinical features were analyzed retrospectively.Results No statistically significant differences were found in the dose-volume parameters of different planning target regions between groups with local tumor recurrence and without recurrence (P ＞ 0.05).In the elective nodal irradiation(ENI) group, neither the recurrence and the non-recurrence groups showed statistical differences in the dose-volume parameters (P ＞ 0.05).While for the involved-field iradiation(IFI) group, the GTV-V60, CTV-V60, PTV-V60 of local recurrent group were significantly lower than those in the non-recurrent group (t =-2.08,-2.19,-2.08, P ＜ 0.05).In the ENI group, radiated doses of GTV, CTV and PTV as well as dose-volume of PTV were significantly higher than the IFI group (t =1.97-3.12, P ＜ 0.05).For patients with a esophageal GTV less than 30 cm3 but without concurrent chemotherapy, radiated dose of CTV-D98％ , CTV-D95％ in the recurrent group were significantly lower than in non-recurrent group (t =-2.24--2.07, P ＜ 0.05).Conclusions Elective nodal prophylactic radiation of esophageal carcinoma could provide greater volume and doses of GTV, CTV and PTV to prescribed target regions, which may decrease local recurrence.Greater efficiency can be obtained when the primary lesion of the esophageal cancer is smaller or at an early stage, and concurrent chemotherapy is not given.

Methods:7 adult patients with mild skeletal Class Ⅱ division 1 malocclusion were included and underwent corticotomy assisted ortho-dontic treatments.3D measurements and analysis of CBCT data before and after treatment were conducted.Results:The average dura-tion of upper anterior teeth retraction was 3.2 months.After treatment,obvious retraction of up incisiors with the retraction of maxillary alveolar bone and the upper lip backward and downward movement were observed.Conclusion:Corticotomy assisted orthodontic treat-ment is effective in the treatment of mild skeletal Class Ⅱ malocclusion by the retraction of uper anterior teeth,alveolarar bone and soft-tissue profile improvement.

Objective Compared with haloperidol treatment,naloxone and naloxone combined haloperidol treatments were assessed in their efficacy and safety for excited type delirium in elderly.Methods The elderly patients with delirium were divided into haloperidol treatment (H),naloxone treatment (N) and combined treatment (C) in a prospective randomized controlled design.Delirium score scale (DSS) was used before and after treatments respectively.Clinical global impression scale-severity of illness (CGI-SI) score was evaluated daily to assess the onset time and improvement of delirium.Agitation-calmness evaluation scale (ACES) observed calmness effect in agitated patients before and after every medication intervention.Treatment emergent symptom scale (TESS) assessed side effects of all medications.Results The duration of three groups(H(4.0 ±2.9)d,N(4.2± 3.5) d,C (3.2 ± 3.2) d) had no significant difference (P ＞ 0.05) by multiple comparison.Compared the onset time of three groups (H (2.4 ± 1.6) d,N (2.4 ± 1.4) d,C (1.3 ± 0.9) d),the combined group was faster than the other two groups (all P ＜ 0.05),no significant difference between the two groups(P ＞ 0.05).DSS scores had no significant differences (P＞ 0.05) in three groups before treatment,so did CGI-SI scores.In the end,DSS scores were(H:18.8 ± 11.5,N:27.7 ± 7.2,C:29.5 ± 5.6) respectively.Statistically naloxone group and combined group with no significant difference (P ＞ 0.05),were better than the haloperidol group (all P ＜ 0.01) in recovery.At the same time CGI-SI scores were (H:3.3 ± 1.5,N:2.5 ± 1.5,C:1.8 ± 0.9) respectively.Statistically combined group was better than the haloperidol group (P ＜ 0.01),and no significant difference with naloxone group (P ＞ 0.05).Three groups had no significant difference in ACES scores (P ＞ 0.05) before and after medication interventions(H:5.9 ± 1.6,N:6.2 ± 1.8,C:6.4 ± 1.6) (P ＞ 0.05).Haloperidol group had 4 cases of extrapyramidal symptom evaluated by TESS and combined group had 2 cases.Two groups had no significant difference (Chisquare test P ＞ 0.05) in extrapyramidal symptom incidence.The naloxone group showed no side effects.Conclusion Naloxone combined haloperidol is slight better than naloxone,more than haloperidol in terms of efficacy.Haloperidol equally with combined medication showed more side effects than naloxone.

ObjectiveTo observe the effect of alcohol exposure during pregnancy on learning and memory and content of hydrogen sulfide(H2S) in the hippocampus of infant rats.MethodsThe animal models of alcohol exposure during pregnancy were made,and the learning and memory were evaluated by Y-maze in adult offspring.Content of H2S and activity of cystathionine-beta-synthase(GBS) in the hippocampus of the brain were evaluated with spectrophotometry;and CBS protein expression in the hippocampus was detected by immunohistochemistry.ResultsThe learning and memory ( (43.00 ± 15.33 ) times) of alcohol exposure during pregnancy group was significantly decreased compared with that of control and drinking groups (( 25.13 ± 12.35 )times and (26.12 ±11.95 ) times,P ＜ 0.05 ) ; spectrophotometry results showed that the content of H2S ( ( 30.32 ± 5.84 ) nmoL/g) of alcohol exposure during pregnancy group was significantly increased compared with that of control ( ( 52.51 ±7.85 ) nmol/g) and drinking groups( (49.93 ± 4.29 ) nmol/g),and the activity of CBS( ( 55.13 ± 4.45 ) nmol/g)of alcohol exposure during pregnancy group was significantly increased (P ＜ 0.01 ) compared with that of control ( (71.06 ± 5.58 ) nmol/g) and drinking groups( (69.96 ± 6.13 ) nmol/g) ; immunohistochemistry showed that the expressionof CBSproteinofalcoholexposureduringpregnancygroupwassignificantlyincreased.ConclusionThe damage effect of alcohol exposure during pregnancy on nerve system of infant rats may interrelate with down-regulation of H2S/CBS in the hippocampus.

Aim To investigate the effects of high glu-cose on cholesterol metabolism in renal tubular cells and the intervention of the anthocyanins. Methods HK-2 cells were grown in the DMEM medium supple-mented with 10% FBS and were divided into 5 groups:normal glucose group, high glucose group, mannitol group, C3G group and Cy group. Effect of anthocya-nins on cell viability was detected with MTT, and cho-lesterol accumulation was detected with Amplex Red Cholesterol Assay kit and Filipin staining. Expression of ABCA1 was detected with RT-qPCR and Western Blot. Results In compared with control groups, HG significantly promoted cholesterol mass inside the cell and decreased the cholesterol concentration in the me-dium after treatment for 24 h or 48 h. The levels of mRNA and protein of ABCA1 were detected with RT-qPCR and Western blot, and both were decreased in the presence of HG. Whereas treatment with C3G and Cy markedly attenuated HG-induced cholesterol mass inside the cell by up-regulating the expression of AB-CA1. Conclusions High glucose can reduce the ex-pressions of the ABCA1, and then decrease cholesterol efflux and increase the cholesterol accumulation in HK-2 cells. Anthocyanins can decrease cholesterol accu-mulation by up-regulating the expression of ABCA1.
