BACKGROUND:We have designed and manufactured a novel artificial cervical vertebra and intervertebral complex (ACVC) which combines the cervical titanium cage with the artificial cervical disc, and also developed the ACVC with a hydroxyapatite biocoating (ACVC-HA). OBJECTIVE:To evaluate biomechanical properties of the joint system, and the role of HA coating in promoting osseointegration and long-term stability. METHODS:Twenty-four goats were randomly divided into three groups and underwent the anterior C2/3 and C3/4 discectomy, and C3 subtotal corpectomy, fol owed by ACVC implantation (group 1) and ACVC-HA implantation (group 2), and given no intervention (black control group), respectively. group. At 12 weeks after surgery, C1-5 samples were col ected to undergo biomechanical tests and histological staining. RESULTS AND CONCLUSION:Prior to the fatigue test, compared with the blank control group, the range of motion and neural zone of groups 1 and 2 in the directions of flexion-extension and lateral bending showed no significant differences, but the above indicators were significantly increased in the direction of rotation (P<0.05). Additional y, the stiffness in al three directions was significantly lower than that in the blank control group (P<0.05). There were no significant differences in the range of motion and neural zone in al directions between groups 1 and 2. Similar results were found after the fatigue test. The histological staining showed that both two implants had good biocompatibility and abradability, but more new bone formed on the ACVC-HA. These results suggest that ACVC can effectively reconstruct the motor function of the cervical spine after decompression. Furthermore, HA coating can markedly improve bone-implant interface to promote osseointegration.

When senescence induction is based on DNA damage, senescent cells display a unique phenotype, which has been termed “senescence-associated secretory phenotype”( SASP ) . SASP, including proinflammatory cytokines, growth factors, chemokines, matrix remodeling enzymes and other cytokines, may be an important driver of chronic inflammation and therefore may be part of a vicious cycle of inflammation, DNA damage and senescence. Senescence-associated secretory products released by such cells can affect the neighboring cells and further exacer-bate their regenerative capacity. SASP is associated with many chronic age-related diseases.

Extending traditional reading popularization model, training reading habit and skill, building classic reading scene, integrating era elements into"classic", using new technology and new media were suggested in this paper for innovating the reading popularization model of classic works on traditional Chinese medicine based on the analysis of why it is difficult to popularize the reading popularization of classic works on traditional Chinese medi-cine.

Objective To assess the relationship between the recurrence of esophageal varices fol?lowing endoscopic esophageal varix ligation (EVL) and esophageal collateral veins(ECV)under endoscopic ultrasound ( EUS) , and analyze the predictive value of EUS for recurrence of esophageal varices. Methods Sixty patients with cirrhotic portal hypertension combined with esophageal varices underwent EVL for eradica?tion of varices. Endoscopy and EUS were performed before ligation to detect and describe the type of esopha?geal varices, and grade, location, and the number of ECV. Over a 12?month period, variceal recurrence was examined. The statistical analyses were performed to assess the relationship between esophageal varices fol?lowing EVL and ECV. Results Of the 60 patients, 29 ( 48?3%) had variceal recurrence within 12 months after EVL. Univariate logistic regression analysis showed that severe peri?ECV ( OR=22?67;95%CI:4?37? 117?47, P<0?001) ,severe para?ECV( OR=16?31;95%CI:0?84?108?14, P=0?018) , multiple peri?ECV ( OR=22?67;95%CI:4?37?117?47, P<0?001) , and the presence of perforating veins ( OR=6?67,95%CI:1?46?30?43,P=0?014) were significantly related to the variceal recurrence after EVL. Multivariate logis?tic regression model showed that severe peri?ECV ( OR=24?39;95%CI:2?34?253?78,P=0?008) and mul?tiple peri?ECV (OR=24?39;95%CI: 2?34?253?78,P=0?008) severe para?ECV(OR=19?42; 95%CI:4?84?148?54,P=0?012) remained independent prognostic factors for variceal recurrence. The sensitivity and specificity of multivariate logistic regression model in predicting variceal recurrence were 89?2% and 90?5%, respectively (prognostic value AUC=0?946).The sensitivity and specificity were 86?4% and 87?7% in pre?dicting variceal recurrence( prognostic value AUC=0?871) . Conclusion Recurrence rate of esophageal var?ices after EVL is high. EUS can clearly depict ECV. Severe peri?ECV and multiple peri?ECV are significant and independent prognostic factors associated with variceal recurrence risk. EUS before EVL will help predict variceal recurrence after EVL.

OBJECTIVETo investigate the trend of total cancer mortality in Linqu County Shandong Province from 1980 to 2002.

METHODSA retrospective survey on all causes of death in 1980 - 1982, 1990 - 1992 and 2000 - 2002 was conducted in Linqu County, a high risk area of gastric cancer in Northeast of China, respectively.

RESULTSThe cancer death, was found the third leading cause of death in 1980 - 1982 in Linqu County, and the second to that of vascular disease in 2000 - 2002. The cancer mortality (standardized mortality) was 108.97/100,000 (111.48/100,000), 132.38/100,000 (127.94/100,000) and 148.48/100,000 (105.53/100,000) in 1980 - 1982, 1990 - 1992 and 2000 - 2002, respectively. The trend of cancer mortality was significantly increased (Z = 13.42, P < 0.0001). The added cancer-eliminated life expectancy in three periods was 2.46 years, 3.29 years and 3.76 years in male (F = 13.99, P < 0.0001), and 1.67 years, 2.30 and 2.33 years in female (F = 13.61, P < 0.0001), respectively. The standardized mortality of gastric cancer (percentage in all cancer death) was 44.93/100,000 (40.29%), 41.37/100,000 (32.34%) and 27.73/100,000 (26.90%) in 1980 - 1982, 1990 - 1992 and 2000 - 2002, respectively. The trend of gastric cancer standardized mortality was significantly reduced (Z = 6.35, P < 0.01).

CONCLUSIONThe mortality of cancer in Linqu County has been increased from 1980 to 2002, but no such trend was found after adjusting ages. However, there was a decreased trend on standardized mortality of gastric cancer in the past 20 years.

OBJECTIVETo investigate the application of double-step distraction osteogenesis in the reconstruction of mandibular segmental defects after tumor resection.

METHODSFrom January 2002 to December 2006, six cases of post-tumor unilateral mandibular segmental defects were reconstructed using distraction osteogenesis. The mandibular body was lengthened first, following by mandibular ramus distraction.

RESULTSNo infection or other complication was observed. The maximal distraction length reached 55 millimeter in the mandibular body, and 42 millimeter in the mandibular ramus. The average distraction length was 52 millimeter in the mandibular body, and 34 millimeter in the mandibular ramus. Both the aesthetic and functional result was excellent in all cases.

CONCLUSIONSDouble-step distraction osteogenesis is effective and easily performed in the reconstruction of unilateral mandibular segmental defects with less morbidities and complications. There is no need for donor site. However, the treatment period is relatively long with three staged operations.

OBJECTIVETo investigate the effect of arctiin on advanced oxidation protein product (AOPP)-induced epithelial-to-mesenchymal transition (EMT) in tubular cells and explore the mechanisms underlying this effect.

METHODSHuman proximal tubular cells (HK-2 cells) were treated with bovine serum albumin (BSA) or AOPPs in the presence or absence of arctiin. The expressions of E-cadherin, vimentin, and GRP78 at the protein and mRNA levels in the cells were examined using Western blotting and quantitative real-time PCR. The level of reactive oxygen species (ROS) was measured by flow cytometry with DCFH-DA as the fluorescent probe.

RESULTSCompared with BSA-treated cells, the cells treated with AOPPs showed decreased expression of epithelial cell marker E-cadherin and overexpression of mesenchymal marker vimentin and endoplasmic reticulum stress marker GRP78 with an increased ROS level. These changes induced by AOPPs were partly inhibited by arctiin.

CONCLUSIONArctiin can ameliorate AOPP-induced EMT in tubular cells by inhibiting endoplasmic reticulum stress, and oxidative stress response may participate in this process.

In this work, a rapid analysis method basing on ultraviolet spectroscopy was established for the determination of danshensu, protocatechuic aldehyde, rosmarinci acid, lithospermic acid and salvianolic acid B in the extraction process of Danhong injection. In the extraction process of Danshen and Honghua crude drugs, 44 extraction solution samples were collected and the contents of the five components were determined by HPLC analysis. The ultraviolet spectra of the samples were collected. Partial least square regression was used to establish the multivariate calibration models between the ultraviolet spectra and the contents of the five components. The results showed that the established models could predict the contents of the five components in the extraction solution accurately. The ultraviolet spectroscopy method established in this work can be used for rapid analysis of the intermediates of Danhong injection, which may be applied for the quality control in the manufacturing process.
