OBJECTIVE:To investigate the effects of Ossotide tabletcombined with Xianling gubao capsule on the postoperative recovery effect oftrans-traumatic-verterbrae screw-setting combined with bone grafting in the treatment of osteoporotic thoracolum-bar vertebral fractures. METHODS:122 patients with osteoporotic thoracolumbar vertebral fractures who were treated with trans-traumatic-verterbrae screw-setting combined with bone grafting were randomly divided into control group and observation group.The two groups were treated by trans-traumatic-verterbrae screw-setting with bone grafting.Based on this,the control group was treated with 0.3-0.6 g Ossotide tablet,three times a day,taken orally after meals;observation group was additionally treated with 1.5 g Xianling gubao capsule,twice a day,taken orally after meals. Both of the two groups took medicine on the day of oper-ation. A course induded 4 weeks,and it lasted 4 courses. The indexes were observed after 3 and 6 months treatment. The changes of pain score,bone mineral density(BMD)levels,bone gla protein(BGP),bone alkali phsphatase(BALP),procollagen I ntermi-nal peptide (PINP) and other bone metabolism biochemical indexes in 2 groups before and after treatment were observed.Mean-while,the clinical efficacy,rates of thoracolumbar vertebral refractures and incidence of adverse reactions in the 2 groups were re-corded.RESULTS:After treatment,the total effective rate in observation group was significantly higher than control group,pain scores in 2 groups were significantly lower than before,and general decreased by time,observation group was lower than control group;BMD,BGP,BALP and PINP levels in 2 groups were significantly higher than before,and general increased by time,ob-servation group was higher than control group;after 6 months,BMD,BALP and PINP levels in control group were significantly higher than before,the differences were statistically significant(P<0.05);there were no significant differences in the incidence of adverse reactions,rates of thoracolumbar vertebral refractures between 2 groups(P>0.05). CONCLUSIONS:Ossotide tablet com-bined with Xianling gubao capsule can significantly improve the bone metabolism biochemical indexes of patients,promote bone mineral density and fracture healing,with good safety in short-term medication.

BACKGROUND:Articular cartilage regeneration can be regulatedbyautocrineorparacrinesecretionof various cytokines.
OBJECTIVE:To analyze biological properties of bone morphogenetic proteins and basic fibroblast growth factor in biological materials for repair of articular cartilage defect.
METHODS:Forty New Zealand white rabbits were used and equaly randomized intofourgroups: fibrin, basic fibroblast growth factor, bone morphogenetic protein, and combined treatment (basic fibroblast growth factor combined with bone morphogenetic protein) groups, respectively.Bioactivescaffolds with fibrin, basic fibroblast growth factor,bone morphogenetic protein, and basic fibroblast growth factor combined with bone morphogenetic protein were injected to repair the articular cartilage defect. Therapeutic effect andbiological properties of biological materials were compared.
RESULTS AND CONCLUSION:(1) Inthefibrin group,tworabbits appearedto havelimps. Inthebasic fibroblast growth factor group hand functionwaslimited inonerabbit. Inthebone morphogenetic protein group, one had a limpandonewasin a limitation of activity. Inthecombined treatment group,rabbitsrecovered wel andshowedno differencesintheknee joint before and aftersurgery (P< 0.05). (2) General observation: Inthe combined treatment group, soft solution cartilage defects disappeared,andangiogenesis and cartilage were similar with normal tissues. Inthebone morphogenetic protein group, fractured cartilage marginal existedand could not beclosely integrated with normal cartilage. The presence of chondrocytesin the periphery of the defectwas seen under light microscope. Inthefibrin group, defect site and surrounding tissues healed. Inthe basic fibroblast growth factor group, defect was repaired, but not smooth. (3) Results ofhematoxylin and eosin staining: Inthefibrin group, the bone defect was not repaired, obvious depression surface was seen. In basic fibroblast growth factor group, repair of cartilage defect was obvious. There were a lot ofchondrocytes. Inthe bone morphogenetic protein group, the bone defect was repaired; chondrocytes appeared, but irregular arrangement. Inthecombined treatment group, good bone defect repair and a large number of cartilage cels were seen. Taken together, biological materials with fibrin and basic fibroblast growth factor are ideal for repair of articular cartilage defect by promoting formation of cartilage by bone morphogenetic protein and enhancing chondrocyte proliferation by basic fibroblast growth factor.

Background Venous malformation damages the local tissue severely because of the progressive development and often presents with invasive biological behavior.Galectin-3 (Gal-3) is proved to be closely associated with local invasion of malignant tumor.Studying the role of Gal-3 on tissue invasion in venous malformation of ocular region is of important clinical significance.Objective This study was to explore the role of Gal-3 protein and mRNA expression in venous malformation of ocular region.Methods One hundred and eighteen pathological sections were collected from ocular venous malformation patients who received surgery in Department of Hemangioma Surgery,People's Hospital of Henan Province and Henan Eye Institute from June 2009 to June 2014.The specimens were further diagnosed by histopathological examination.Then the expressions of Gal-3 protein and mRNA in venous malformation of ocular region were detected by using immunohistochemistry and in situ hybridization and compared with 20 pieces of distal cutting edge specimens which were evidently normal.The associations of Gal-3 positive expressions with invasion and configuration of lesions were analyzed.Results Pathological examination showed that venous malformations tissues contain many big blood vessels lacuna, lined with fiat endothelial cells.Immunochemistry and in situ hybridization exhibited that Gal-3 protein and mRNA were expressed in the cytoplasm and nuclei.The positive expression rates of Gal-3 protein and mRNA in the venous malformation tissues were 55.93％ (66/118) and 59.32％ (70/118) , but those in the normal tissue were 15.00％ (3/20) and 20.00％ (4/20) ,showing significant differences between them (x2 =11.461, 10.633, both at P＜0.05).No significant differences were seen in the positive expression rates of Gal-3 protein and mRNA between the patients aged ≤ 12 years and ＞12 years or different genders (age: x2 =0.334,0.128;both at P＞0.05.gender:x2 =0.606,1.155;both at P ＞0.05).The incidence rate of invading ocular deep tissues was significantly higher in the Gal-3-positive groups than that in the Gal-3-negative groups of protein and mRNA (protein :x2 =32.688, P＜0.05;mRNA : x2 =23.695, P＜0.05).In the Gal-3-negative groups,96.15％ (Gal-3 protein negative group) and 97.92％ (Gal-3 mRNA negative group) lesions showed the spherical shape with clear boundaries.The lesions texture with the fuzzy boundaries and the incidences of vague structure in lesions were significantly higher in the Gal-3-positive groups than that in the Gal-3-negative groups of protein and mRNA (protein :x2 =28.255, P＜0.05;mRNA : 28.186, P＜0.05).Conclusions Gal-3 expression rate is raised in the deep tissue-invaded and texture disorder ocular venous malformation.These results suggest that invasion and damage of ocular venous malformation are associated with the up-regulation of Gal-3.

Objective: To study the compatibility and therapeutical basis of composite herbal medicines of Lingguishugan Decoction(LD)(Poria, Ramulus Cinnamomi, Rhizoma Atractylodis Macrocephalae, Radix Glycyrrhizae.)Methods: Ethanol extract test solutions of the different combinations were prepared according to the orthogonal layout L 16 (4 5). Pharmacologic experiments, such as the time of survival of mice in shortage of oxygen in normal pressure, the antagonistic effect on arrhythmia induced by chloroform and the diuretic effect were carried out with LD. Variance analysis, canonical correlation and stepwise regression analysis were applied to interelationship between the amount of each drug and the pharmacologic data. Then, the fingerprints of the solutions were tested by HPLC method and 50 chromatographic peaks were obtained. Correlation and regression analysis was applied to interelationship between the area of each peaks and the pharmacologic data.Results: The results confirmed the poria and cinnamon twig are the basis, while ovate atractylodes and licorice are the adjuvans. 17 peaks, which were established as the therapeutical basis of the decoction, were selected from all compounds, and cinnamic acid of cinnamomum cassia, glycyrrhizin of Glycyrrhiza uralensis and dehydrotumulosic acid of Poria cocos were selected as the markers to evaluate the quality of the decoction.Conclusion: This study provided a significant try of studying the compatibility of composite herbal medicines.

Objective To evaluate regional blood flow occlusion (RBFO) in hepatectomy for liver neoplasms. Methods In this study, hepatic tumors were resected under RBFO in 28 cases (RBFO group), and under Springle's technique (control group) in 24 cases. The Child-Pugh classifications of liver function were grade A in all patients. The ligature ribbon was put in liver parenchyma around tumor to block the blood supply before resecting the tumor under guiding of B sounography in RBFO group. Anesthesia time, blood loss and transfusion, hospitalization, change of liver function and complications were compared between the two groups. Results Blood loss, anesthesia time and postoperative hospital stay were (340±92) ml, (98.4±25.0) min, ( 10.2±2.3 ) d in RBFO group and (620±124) ml, ( 135.8±47.5 ) min, (16.5±5.1 ) d, respectively, in control group, differences were all significant between the two groups (P <0.01, t = 9.222,9.328 and 5.875, respectively). On post-op day 2, ALT (U/L) was (378.4±35.2) vs. (539.2±115.4) (t=7.012, P<0.01), TBIL (37.5±11.2) vs. (51.8±29) mmol/L(t=8.818, P<0.01),PT (17.4±2.4) vs. (20.4±2.8) see(t =4.16, P<0.01) in RBFO group and control group, respectively. ALT was (57.1±15.5) vs. (98.1±21.2) U/L(t =8.039),TBIL (25.4±4) vs. (46.3±13) mmol/L(t=8.085),PT (13.2±4.2) vs. (15.7±2.2) see (t=2.621)on post-op day 7 respectively, again the differences were all significant between the two groups (all P<0.01). Conclusion Regional blood flow occlusion is an effective technique to control blood loss during hepatectomy for liver neoplasms.

AIM: To investigate the effect of advanced glycosylation end products on the expression of receptor for advanced glycosylation end products in human monocyte-derived dendritic cells. METHODS: Monocytes were purified (over 98%) using anti-CD14+ microbeads. After 8 d culture in RPMI-1640 medium containing rhGM-CSF (100 ?g/L) and rhIL-4 (50 ?g/L), immature MDCs were derived, then exposed to AGE-BSA (0 or 200 mg/L) for 24 h. Expression of RAGE was semi-quantified by RT-PCR and Western blotting. At the same time, supernatants were collected. IFN-? and IL-12 were analyzed by ELISA. RESULTS: mRNA and protein of RAGE incubated by 200 mg/L AGE-BSA was higher than that in control at 24 h. Treatment of DCs with AGE-BSA resulted in about two-fold increase in the expression of RAGE (P

Objective To assess the clinical value of volume helical shuttle (VHS) of highdefinition CT (HDCT) in the diagnosis of congenital heart disease (CHD).Methods Forty-three patients suffering from CHD were examined with VHS of HDCT and echocardiography (ECHO).Twenty-four patients (21 children,3 adults) received surgery.Based on surgical data,the diagnostic accuracy of CHD by VHS of HDCT was compared with that by ECHO with respect to the intra-cardiac lesion,extra-cardiac lesion and hemodynamics.The visibility of the origin and proximal course of coronary arteries was also evaluated on VHS.CT effective doses were calculated,using mSv =DLP × K. Results Thirty-six intra-cardiac deformities were found by operation,and the diagnostic accuracy of both VSH and ECHO were 100.0％ (36/36).VHS successfully detected 42 of 44 (95.4％) cardiac-vascular connection and large vascular deformities,whereas ECHO only detected 26 (59.1％ ).The right-to-left shunt and left-to-right shunt of septal defects revealed by VHS were 5 and 6 patients respectively,which all coincided with the results of ECHO.Fourteen bi-directional shunt of septal defects were detected by ECHO,and 13 of them were diagnosed as right-to-left shunt by HDCT except an illegibility in 1 patient.The origin and proximal course of coronary arteries were all visible on VHS.Effective dose for children was (3.38 ± 1.86) mSv,and for adults was ( 10.27 ± 2.59) mSv.Conclusions VHS of HDCT scan is advantageous in the diagnosis of CHD.It can depict the intra- and extra- cardiac structures as well as coronary arteries and provide hemodynamic information.
