Objective To explore the possible effect of combined treatment of zoledronic acid and doxorubicin on proliferation,invasion and adhesion of SGC7901 cell line,and potential underlying mechanisms. Methods MTT and Transwell experiments were used respectively to investigate the effect of different concentrations of zoledronic acid and doxorubicin on the proliferation,adhesion and invasion of SGC7901. The mRNA levels of MMP2, TIMP2, MMP9, ICAM1 and CD44 were quantified by real time PCR. Results Gastric cell line SGC-7901 were incubated with zoledronic acid for 48 h in different concentration of 10-6,10-5,10-4,10-3 mol/L,their inhibition rates were 4.98％,12.19％,27.34％ and 73.13％ separately,which were higher than control group (P＜0.01),and enhanced along with the dose increasing and the time extension (P＜0.05).Gastric cell line SGC-7901 was incubated with zoledronic acid 10-4 mol /L and doxorubicin 0.5 mg/L,respectively,or in combination for 2 h,4 h,6 h,and thereafter,the detected adhesion rates were 5.03％,24.38％ and 59.65％ in control group,4.40％,19.77％ and 51.22％ in zoledronic acid group,4.28％, 18.62％ and 51.02％ in doxorubicin group,4.02 ％,15.02％ and 46.95％ in combination group. The adhesion rates were reduced after incubation with different medicament concentration (P＜0.05).In the study of cell invasion,the cell numbers per high power field were:105.11 ± 10.43,98.37 ± 15.75,96.19 ± 9.24,83.02 ± 19.72 after treatment with zoledronic acid,doxorubicin or their combination at different concentrations. Compared with control, signal medicament had weak effectiveness in invasiveness in SGC-7901 (P＞ 0.05),whereas in combination group it was significantly decreased (P＜0.05).Both zoledronic acid and doxorubicin decreased the mRNA expressions of CD44,MMP2,MMP9,ICAM1 while increased TIMP2 mRNA level (P＜0.05or P＜0.01) versus control.The effect was more evident with combination treatment(P＜0.05 or P＜0.01),compared with doxorubicin group. Conclusions Both zoledronic acid and doxorubicin can inhibit the proliferation,adhesion and invasion of SGC7901. Combination treatment has additive effect.It may be related to the down-regulation of mRNA of ICAM1,MMP2,MMP9,CD44 and up-regulation of mRNA of TIMP2.

This study aims to explore the impact on patient's liver and kidney function by different dosage of Kudiezi injection. This study retrospectively analyzed 15 228 patients' records from 18 nationwide general hospital information system (HIS). All patients were treated with Kudiezi injection, 1 956 patients that were given doses of > 40 mL, which is above the recommended dose, acted as the observation group. Fifty-five patients receiving the recommended dose of < 40 mL were the control group. Data about alanine aminotransferase (ALT), aspartate aminotransferase (AST), creatinine (Cr) and blood urea nitrogen (BUN) were collected before and after using Kudiezi injection, changes after treatment were outcomes. Also recorded were: age, costs, length of hospitalization and the patients' condition on admission. Propensity score method was used to balance 71 confounding variables such as gender, age, mortality, and costs. There were no significant difference on the four indexes between the two groups. It is hard to conclude that the use of Kudiezi injection over the recommended dose could influence the four indexes of liver and kidney from this data analysis. More conclusive evidence should be collected by further prospective study.

OBJECTIVETo investigate whether signaling through Toll-like receptor-2 (TLR-2) can affect the expression of some cytokines in human gingival fibroblasts.

METHODSThe gingival fibroblasts were isolated and cultured in vivo, divided into blank control group, lipopolysaccharide (LPS) from Porphyromonas gingivalis (Pg) group and Escherichia coli (Ec) group. mRNA expression levels were measured by real-time polymerase chain reaction (PCR). The protein expression levels were detected by the enzyme linked immunosorbent assay (ELISA). The data was statistically analyzed by SPSS16.0 software package.

RESULTSLPS from Pg could stimulate the expression of interleukin (IL)-6 and leukemia inhibitory factor (LIF) mRNA and protein, which reached the peak (5.87 ± 0.83) at 10 h, and the expression level increased with the increase of the Pg concentration. IL-11 or oncostatin-M (OSM) mRNA expression was not affected by LPS. After treated with Pg for 48 h, the protein expression of IL-6 and LIF was up-regulated, (962 ± 57) ng/L and (47 ± 18) ng/L respectively.

CONCLUSIONSSignaling through TLR-2 controls the expression of cytokines of IL-6 family in human gingival fibroblasts.

Objective To evaluate the effect of heparin binding epidermal growth factor-like growth factor (HB-EGF)on liver regeneration after partial orthotopic liver transplantation.Methods Fourty SD rats were used to establish the model of partial orthotopic liver transplantation with ameliorated two-cuff technique.Then all the rats were divided into 2 groups:experiment group and control group.Twenty rats of experiment group were adminis- tered 500?g/kg HB-EGF via vena caudalis immediately after operation twice a day,while the same volume of saline was administered to the rats in control group.Five rats in each group were selected randomly and killed at the 6th hour,day 2,4 and 7 after operation,respectively.The serum levels of albumin(Alb)and alanine aminotransferase (ALT)in the blood sample were detected.Every liver was removed and weighed.The expression of Ki-67 was de- tected by using immunohistochemistry assay.The regeneration activity of hepatocytes was evaluated by flow cytom- etry.Results The wet weights of liver in experiment group were all significantly higher than that in control group at the 6th hour,day 2 and 4 after transplantation(P

Objective To summarize the causes and strategies of reoperation in cervico-occipital diseases,so as to minimize the incidence of reoperation.Methods Between January 2000 and January 2012,23 patients who underwent reoperation in our hospital because of severe complications of cervico-occipital diseases were retrospectively analyzed.There were 14 males and 9 females with the age at primary surgery range from 18-52 years.The interval between reoperation to primary surgery was 3 h-11 years.The reasons of reoperation included pseudarthrosis in 15 cases,aggravated neurological deficit in 3 cases,internal fixation failure in 2 cases,cerebrospinal fluid leakage in 1 case and tumor recurrence in 2 cases.All patients presented with continuous neck pain,numbness of the limbs or pyramidal tract signs.11 patients suffered from neurological deficit,with the average JOA score of 7.8.All patients underwent excision of posterior arch or decompression of foramen magnum,iliac bone grafting,atlantoaxial or occipital-cervical fusion.JOA score and radiograph were used to evaluate the surgical outcome during follow-up.Results The operation was completed successfully in all cases.The average surgical time was 160 min (130-310 min),and the average blood loss of 800 ml (range 300 to 2000 ml).No intraoperative vascular,nerve and spinal cord injury.There were no postoperative neurological deterioration,pharyngeal wall and intraspinal infection.Two cases of postoperative wound infection,healing by dressing change and prolong the use of antibiotics.No severe complications were noted.All patients were followed up for an average of 21 months (6 months-3 years).At the final follow-up,the JOA score was significantly better as compared with preoperation,with an average of 13.2.Based on Macnab criteria,there were 11 excellence,8 good,4middle.Bone fusion was achieved in all patients without instrumentation failure at final follow-up.Conclusion The main reasons of reoperation in cervico-occipital diseases are pseudoarthrosis and remnant symptoms,effective fusion and decompression are the key points to reduce reoperation rate in cervicooccipital operation.

Objective To observe the therapeutic effect of methylphenidate hydrochloride controlled-release tablets (OROS-MPH) on attention-deficit hyperactivity disorder (ADHD). Methods Seventy-two cases of children with ADHD were randomly divided into treatment group (40) and control group (32). Cases of treatment group were given 0.8-1.0 mg??kg-1 of OROS-MPH for three months. Cases of control group were given 1.2-1.4 mg??kg-1 of atomoxetine hydrochloride for three months. After 12 weeks treatment, children were evaluated by Wechsler intelligence test, Integrated visual and auditory continuous performance test (IVA-CPT), the SNAP-Ⅳ effect assessment scale and TESS scale. Results The treatment efficiency was similar in both groups. Attention deficit and hyperactivity in both groups were improved obviously. Wechsler intelligence score was significantly elevated ( P<0. 05), SNAP-Ⅳ score was significantly decreased ( P<0. 05), and IVA-CPT score was increased significantly after treatment ( P<0.05) . The changes of scores on hyperactivity, auditory attention and visual attention were more in OROS-MPH group than those in atomoxetine group(P<0.05). There was loss of appetite in 10 children of OROS-MPH group and in 14 children of atomoxetine group. There was drowsiness in 1 child of OROS-MPH group and in 5 children of atomoxetine group, as well as difficulty to fall asleep in 6 children of OROS-MPH group and 1 child of atomoxetine group (P<0.05). One child developed a transient spasm after 4-month treatment. Conclusion Both of OROS-MPH and atomoxetine hydrochloride can improve learning ability and the symptom of attention deficit and hyperactivity, and they are similarly effective and safe in children with ADHD, but OROS-MPH can work faster.

Objective To investigate the change of matrix metalloproteinase-9 (MMP-9) and tissue inhibitor of metalloproteinase-1 (TIMP-1) in the skin of diabetic rats, and to explore the potential role of MMP-9/TIMP-1. Methods Diabetic rats were induced with streptozotocin (STZ). Then all rats were maintained for 6 weeks. Routine pathological examination and immnnohistochemistry were made to reveal the histological and cytological appearances. RT-PCR and Western blotting were used to detect the expression of mRNA and protein of MMP-9 and TIMP-1 in the skin. Results Six weeks after STZ treatment, examination of HE-stained skin sections from normal and diabetic animals revealed that the epidermis and dermis layers were thinner in diabetic rats than those in control rats. The skin of diabetic rats showed features of atrophy such as disorganization of connective tissue fiber bundles and enlarged space between collagen fiber bundles. In contrast, thick bundles of connective tissue were observed in the dermis of normal rat skin. In normal skin, cells had a bipolar, spindle-shaped appearance in the thick collagen bundles, while in the skin of diabetic animals the interstitial cells had a rounded, shrunken and crenated appearance. The relative values of expression of MMP-9 in diabetic group were higher than those in normal group with significant difference, however, the relative values of expression of TIMP-I in diabetic group were lower than those in control group. Conclusion The changes in cutaneous histology and cytology appear earlier than skin wound. These "underlying disorders" may be associated with the imbalance of MMP-9/TIMP-1.
