OBJECTIVE: To study the therapeutic effect of treating knee arthropathy with total knee arthroplasty using rotating-platform knee prosthesis. METHODS: A total of 62 patients (74 knees) in Provincial Hospital Affiliated To Shandong University from January 2005 to January 2009 were selected, including 36 males (41 knees) and 26 females (33 knees), aged 52-79 years, mean aged 61.5 years; 28 cases with left knee, 22 cases with right knee and 12 cases of both knees. The cases were composed of 34 cases with osteoarthritis, 21 cases with rheumatoid arthritis and 7 cases with traumatic arthritis. All the patients received the total knee arthroplasty for the first time using rotating-platform knee prosthesis, no replacement of the patella. The clinical results of pre-operetion and after-operation were evaluated by the HSS knee rating score system. RESULTS: All the patients were followed-up for averaged 22 months (3-48 months) after operation. Incisions of all the cases were healed, and there was no infection and hematoma. Lower extremity deep venous thrombosis occurred in 2 cases at 3 days after operation. Swelling disappeared through drug treatment 10 days later. Pain and function of all the patients were obviously ameliorated after operation. The average HSS knee rating score was 44.99 (from 34 to 58) before total knee arthroplasty, which was improved to 88.78 (from 69 to 98), and the good-to-excellent rate was 98% (excellent 45 cases, good 16 cases, average 1 case). There were no signs of prosthetic dislocation or loosening in the X-ray films. CONCLUSION: Total knee arthroplasty using rotating-platform knee prosthesis owns advantages of easy surgical operation, tess complications, good recovery and satisfactory results in a short-term.

Background and purpose:Vascular endothelial growth factor(VEGF) is a potent angiogenic mediator and angiogenesis has important effects on tumor growth and metastasis.The present study was to investigate the relationship between genetic polymorphism of VEGF and heredity risk factor of lung cancer.Methods:VEGF genotypes were determined by PCR-RFLP method in 171 patients with lung cancer and 172 healthy controls.Software PHASE 1.0 was used to construct the haplotypes of every individual.Unconditional logistic regression model was used to analyze the statistical association of genotypes or haplotypes in the two groups adjusted by gender and age. Results:Individuals with at least one-2578A allele had a significantly decreased risk of lung cancer compared with those carrying-2578CC genotype.When the analyses were stratified by gender,the combined-2578 CA and AA genotype,were associated with a considerably reduced risk of lung cancer(P=0.001,OR=0.303,95%CI=0.15 3-0.601).The distribution of the two haplotypes(936C/-2578C and 936C/-2578A) among overall lung cancer cases was significantly different from that among the controls(P=0.016,0R=0.317,95%CI=0.124-0.809 and P=0.018,OR=0.547, 95%CI=0.331-0.903).When the cases were categorized by tumor histology,the distribution of C-C haplotype in the adenocarcinoma(AC) group was associated with a substantially lowered risk of AC(P=0.004,0R=0.237,95%CI=0.090- 0.627),compared with the reference haplotypes.Conclusion:VEGF polymorphism may be a critical risk for the genetic risk factor to lung cancer.

Objective To investigate the present status of Kaschin-Beck disease(KBD) in Qingzhou at present, and provide a scientific basis for decision-making in controlling the disease. Methods According to The National Technical Scheme for Endemic Disease Control in 2007, children aged 7 to 12 were chosen to receive clinical and X-ray examination in 3 villages of 2 towns in Qingzhou. Local adults aged 16 years and older were clinically diagnosed in 10 villages of 4 towns and divided into different groups according to the clinical degrees and their ages. The Diagnostic Criteria of Kashin Beck Disease(GB 16003-1995) was carded out by clinical and X-ray diagnosis. Results Two hundred and sixty school children aged 7 to 12 were clinically diagnosed, and the patients of I degree upwards of KBD were not detected. One hundred and ninety-eight school children aged 7 to 12 were examined by X-ray, and the detectable rate was 0(0/198). In 7099 adults aged 16 years old upwards clinically tested, 502 patients of degree I and higher of KBD were detected and the detectable rate was 7.07%(502/7099). The patients distributed mainly in the population aged 36 years old and older, accounting for 99.00% (497/502). Conclusions Although KBD in children have been controlled in Qingzhou, it is still serious in adults. So the monitoring of KBD should be carried on and prevention and control for KBD in adults should be strengthened.

OBJECTIVETo investigate the factors upgrading the International Society of Urological Pathology (ISUP) Gleason score using the specimens from preoperative prostatic biopsy and radical prostatectomy.

METHODSA total of 164 patients diagnosed with prostate cancer by biopsy underwent radical prostatectomy. We retrospectively analyzed their age, prostate volume, preoperative PSA level, PSA density (PSAD) , the time interval between biopsy and surgery, the number of positive punctures, positive surgical margin, seminal vesicle invasion, lymphatic invasion, and Gleason scores from biopsy and prostatectomy. We also determined the predictors of Gleason score upgrading by logistic regression analysis.

RESULTSOf the 164 cases analyzed, 95 (57.93% ) showed a consistency between the Gleason score of preoperative prostatic biopsy and that after radical prostatectomy, 55 (33.54% ) increased and 14 (8.52%) decreased after prostatectomy as compared with preoperative biopsy. The prostate volume (P < 0.01) and biopsy score (P < 0.05) were independent predictors of Gleason score upgrading. The risk of Gleason score upgrading was 27 times higher in the patients with the prostate volume ≤ 25 ml and 9 times higher in the 25-40 ml group than in the > 60 ml group (P < 0.05).

CONCLUSIONLow Gleason score of biopsy (≤ 6) and small prostate volume (≤ 40 ml) may be the predictors of Gleason score upgrading after radical prostatectomy.

OBJECTIVETo investigate HIV-1 co-receptor usage in patients experienced anti-retroviral therapy (ART) in Anhui and Henan province of China.

METHODSA total of 45 HIV-1 infected individuals who have experienced ART and 109 un-experienced ART patients from Anhui and Henan province, which were called as treatment group and treatment-negative group, were selected as study subjects. HIV-1 strains were isolated from peripheral blood mononuclear cells of whole blood from patients. HIV-1 p24 in the culture supernatant was measured using a commercial enzyme-linked immunosorbent assay (ELISA) kit. HIV-1 co-receptor usage was identified using Ghost cell lines expressing CD4 and the chemokine receptor CCR5 or CXCR4.

RESULTSAmong 45 HIV strains from the treatment group, 22 (48.9%) strains used CCR5 as a co-receptor (R5 tropic strain), 21 (46.7%) strains used CXCR4/CCR5 as a co-receptor (X4/R5 duel tropic strain), and 2 (4.4%) used only CXCR4 as a co-receptor (X4 tropic strain). In 109 strains from treatment-negative group, 96 (88.1%) strains used CCR5 as a co-receptor (R5 tropic strain), 13 (11.9%) strains used CCR5/CXCR4 as a co-receptor use (X4/R5 strain). A significant difference was found between two groups in X4 co-receptor usages (χ(2) = 27.30, P < 0.05). Furthermore, after treated with AZT + DDI + NVP, the HIV-1 CXC4/CCR5 utilization was 59.09% (13/22), meanwhile after treated with D4T + DDI + NVP, the HIV-1 CXC4/CCR5 utilization was 43.48% (10/23), which the difference was not statistical significant (χ(2) = 1.10, P = 0.30).

CONCLUSIONHIV-1 CXCR4/CCR5 co-receptor utilization was higher in ART patients than treatment-negative patients.

OBJECTIVE: To investigate whether heroin can directly induce apoptosis in primary cultured cortical neurons of rat's brain. METHODS: Cultured primary neurons cultures were obtained from cerebral cortex of embryo rats. After 7 days, the cells were incubated with different concentrations of heroin (purity-80%) for 24 hours. The neuronal survival was assessed by cell viability counting with fluorescent diacetate (FDA) staining. The morphological and biochemical changes were observed with Hoechst 33258 fluorescent staining and then analyzed by agarose gel electrophoresis, respectively. RESULTS: After treatment with different concentrations of heroin, the neurons showed a decreased survival rate in a dose dependent manner, and there was a significant difference in the survival rate between the heroin group and the control group (P < 0.05). When exposed to different concentrations of heroin, neurons exhibited the morphological and biochemical features of apoptosis, including cell shrinkage, neurite degeneration, network disappearance, condensation and aggregation of nuclear chromatin, and the formation of DNA ladders. With the increase of heroin concentration of rat's brain more apoptotic bodies were seen. CONCLUSION Heroin can directly induce apoptosis in primary cultured cortical neurons in rat's brain.

Objective:By means of network pharmacology, the active ingredients, targets and molecular pathways of Shengmaiyin (Dangshen prescription) in the treatment of atherosclerotic cardiovascular disease (ASCVD) were studied, in order to reveal the molecular mechanism of Shengmaiyin (Dangshen prescription) in the treatment of ASCVD, and provide the rational explanation of the compatibility of the combination. Method:The main chemical components of Shengmaiyin (Dangshen prescription) were obtained by means of SymMap database, traditional Chinese medicine systems pharmacology database and analysis platform（TCMSP）platform and BATMAN-TCM platform. Compound targets were retrieved by SymMap and the Encyclopedia of Traditional Chinese Medicine （ETCM）, and disease targets were retrieved by DisGeNET and GeneCards databases. The intersections of compound targets and disease targets were used to obtain the predicted targets of song-decoction on ASCVD. The Protein-Protein Interaction (PPI) network diagram was constructed through STRING database, and key compounds and targets of Shengmaiyin (Dangshen prescription) acting on ASCVD were obtained through Cytoscape. Finally, the enriched key targets were put for Gene Ontology (GO) biological process analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis through the Database for Annotation，Visualization and Integrated Discovery（DAVID）. Result:There were 33 key compounds and 25 key targets of Shengmaiyin (Dangshen prescription) for ASCVD. The GO analysis showed that the biological functions of Shengmaiyin (Dangshen prescription) in the treatment of key ASCVD targets mainly involved biological processes, such as the regulation of apoptosis, inflammatory response, regulation of nitric oxide synthesis and regulation of insulin secretion. The KEGG pathway was mainly enriched in 20 signaling pathways, including tumor necrosis factor(TNF) signaling pathway, phosphatidylinositol 3-kinase/protein kinase B(PI3K/Akt) signaling pathway, apoptosis signaling pathway and estrogen signaling pathway. Conclusion:Through network pharmacology, this study explored active ingredients and potential targets of Shengmaiyin (Dangshen prescription) in the treatment of ASCVD at the molecular level, preliminarily verified the mechanism of action of Shengmaiyin (Dangshen prescription), and laid a theoretical foundation for further study on the mechanism of action.
