Patients in Orthopedics have different psychological features in the stages of before treatment,the stage of treatment,the stage of rehabilitation and the stage of post-discharge.The health care workers should use language and non-verbal skills to communicate with patients according to their psychological characteristics,and adopt different communication skills with different individuals.A good communication not only reduces the disputes between doctors and patients,but also promotes physiologic and psychological rehabilitation.

Equipping tumor-targeting carrier with cell-penetrating peptide with high transduction efficacy has become a trend. According to the fusion modes and tumor-targeting mechanisms, cell-penetrating peptides can be divided into five categories: first, self-targeting cell-penetrating peptides; second, fusion carriers made of targeting ligands and cell-penetrating peptides; third, cell-penetrating peptide-modified nano-carrier; fourth, tumor-microenvironment-targeting cell-penetrating peptides; fifth, other special cell-penetrating peptides. Fusion carriers, which can not be effectively released into the cytoplasm after transducted into target cells, can be further modified to increase their efficacy. In all, cell-penetrating peptide introduced into tumor-targeting carrier should provide a new era for anti-tumor pharmacy research and cancer therapy.

Objective To analyze the drug therapeutic regimen and duration of the chemotherapy in the spinal tuberculosis in order to determine the best therapeutic regimen and duration of the spinal anti-tuberculo-sis. Methods The medication plan and duration of 890 hospitalized patients with spinal tuberculosis in our hospital from January 2001 to December 2008 were retrospectively investigated. We collected the plan of the initial treatment,retreatment,recrudescence and drug resistance. We also studied the individuation therapeutic regimen of the patients with tuberculosis at other parts or complications. On the basis of these data,we analyzed the interferential appearance that the antituberculosis drug acted on different onsets,manifestations and operations. Results In 890 patients of spinal tuberculosis,596 cases ( 67% ) were initial treatment,294 ( 33% ) were retreatment,recur cases were 110 ( 12. 3% ) ,drug resistance cases were 74( 8. 3% ) ,and those compli-cated with tuberculosis in other parts were 273 ( 30. 7% ) . The main chemotherapeutic regimen was the usual tetragenous protocol ( H12 /R12 /E9 /Z5 /S3) . The retreatment cases were given second-line drugs such as levo-floxacin. The drug resistance cases were also given second-line drugs and intravenous infusion. According to the anti-tubercle bacillus spectrum,individuation treatments were adopted,and the plan was changed in time. The medication duration continued for 9-36 months. All the 890 patients were cured. Conclusion For the treatment of spinal tuberculosis,it is significance to make a efficient and standardized anti-tuberculosis chemotherapy.

Objective To explore the content of peripheral blood T lymphocyte subsets and natural killer (NK) cells in diffuse large B-cell lymphoma (DLBCL) in different clinical stages and analyze their clinical significance.Methods Sixty-two DLBCL patients were divided into 3 groups according to clinical stages:stage Ⅱ group (21 cases),stage Ⅲ group (21 cases ),stage Ⅳ group (20 cases).Thirty healthy examiners were selected as control group.Two ml peripheral blood was taken from every person.Peripheral blood T lymphocyte subsets(CD3+,CD4+,CD8+) and NK cell count were detected by flow cytometry(FCM) and CD4+/CD8+ was calculated.Results CD3+ in stage Ⅱ and Ⅲ groups[(854.6 ± 276.9 ) × 106/L,(823.3 ± 211.5)× 106/L] were lower than those in control group[(1268.8 ±684.0) × 106/L] and stage Ⅳ group [(1332.7 ±571.2) × 106/L](P ＜ 0.05).CD4+ in stage Ⅱ,Ⅲ,Ⅳ groups [(433.5 ± 240.7) × 106/L,(423.8 ± 234.8) ×106/L,(423.0 ± 143.8 ) × 106/L] were lower than those in control group [(751.3 ± 367.4) × 106/L] (P ＜0.05).CD8+ and CD4+/CD8+ in stageⅣ group [(861.2 ±634.1) × 106/L,0.5 ±0.3] were significantly higher than those in control group [(455.9 ± 334.6) × 106/L,2.1 ± 1.3],stage Ⅱ group [(390.6 ± 54.1 ) × 106/L,1.0 ±0.8] and stageⅢ group [(377.4 ±493) × 106/L,0.9 + 0.6](P＜0.05).NK cell in stage Ⅳgroup was obviously lower than that in control group[(210.3 ± 122.0) × 106/L vs.(353.3 ± 284.7) × 106/L,P＜ 0.05].And the higher clinical stage was,the lower NK cell was.Conclusions With the clinical stage increasing,the immunity depression and disorder of DLBCL patients become more and more serious,the more tumor burden is,the worse NK cell activity is.

ObjectiveTo explore the relationship between the international prognosis indexes(IPT) and the cell-mediated immunity condition in DLBCL patients. Methods52 DLBCL patients were divided into 4 groups and the FCM was used to examine the T lymphocyte subsets,including CD3+、CD4+、CD8+、NK cells.T lymphocyte subsets absolute value and CD4+/CD8+ ratio were examined. Correlation with IPI were compared among groups.ResultsCD3+ cells in high risk group [(1570.9±370.5)/μl]were higher than other IPI groups;CD4+ cells in DLBCL groups were all lower than normal group(751.3±367.4)/μl]; CD8+ cells in high risk group [(1055.9±523.8)/μl] were higher than other groups; CD4+/CD8+ ratio in middle-high risk group and high risk group (1.0±0.2、0.7±1.0)were lower than other IPI groups and normal group;NK cells in middle-high risk group and high risk group were lower than the normal group[(199.5±68.4)/μl、(171.9±126.9)/μl];Age,clinical stage,body state had correlated with the CD3+ 、CD8+ cells and CD4+/CD8+ ratio of the DLBCL patients' peripheralblood T lymphosyte subsets. ConclusionsThe immunity condition in DLBCL patients has correlated with IPI; With increasing IPI value,the immunity depression and disorder become more serious,NK cells function become worse,and the prognosis is bad too.

Objective To investigate the influence of epigallocatechin gallate ( EGCG)on reactive oxygen species (ROS) in mouse podocytes exposed to high glucose. Methods Mouse podocytes cultured in high glucose were exposed to different concentrations of EGCG (0.2, 10, 100 μmol/L) or α-tocopherol (0.2 μmol/L) for 6, 12, 24 hours. The viability of podocytes was detected by MTT. The intracellular formation of ROS was detected by confocal microscopy with fluorescent probe CM-H2DCFDA and was measured by fluorescence microscopy. RT-PCR was used to examine the expression of p22phox, p47phox and p67phox mRNA in cultured podocytes exposed to different concentrations of EGCG. Results Intracellular ROS generation was significantly higher in high glucose than that in control conditions (P<0.01). EGCG could significantly inhibit ROS induced by high glucose significantly (P<0.01). EGCG (100 μmol/L) led to an inhibition of the increased production of NADPH oxidase components of p22phox and p67phox mRNA in high glucose (P<0.05). The expression of p47phox mRNA in high glucose was inhibited by EGCG(0.2 μmol/L) and ot-tocopherol(0.2 μmol/L) (P<0.05). Conclusion EGCG can protect cultured mouse podocytes from injury of high glucose by inhibiting ROS formation.

Objective To investigate the serum levels of procalcitomn (PCT) and high mobility group box chromosomal protein-1 ( HMGB1 ) in patients with acute pancreatitis (AP) ; and study the relationship between the serum levels of PCT,HMGB1 and the severity and prognosis of AP.Methods The blood samples were collected from 80 AP patients,including 38 severe acute pancreatitis (SAP) patients and 42 mild acute pancreatitis (MAP) patients.The serum levels of HMGB1 were measured by ELISA kit,and the levels of PCT were measured by immunoassay chemiluminescent technique,then their relationship with other biochemical parameters,the severity and prognosis of AP was analyzed.30 healthy adults were treated as the control group.Results The serum PCT and HMGB1 levels were ( 8.18 ± 3.24) μg/L and ( 11.79 ± 3.98 ) μg/L in SAP group,and the corresponding values were (5.67 ± 2.43) μg/L and ( 5.38 ± 2.06) μg/L in MAP group,and both were significantly higher than those in control group [ ( 1.85 ± 0.86) μg/L and ( 1.87 ± 1.47) μg/L,P ＜0.01 ].The serum level of PCT was positively correlated with serum 1evel of HMGB1 ( r =0.276,P =0.014),and both were positively correlated with Ranson score,APACHE Ⅱ score,Balthazar CT score (P＜0.05 or ＜0.01 ).The HMGB1 levels were significantly higher in patients with organ dysfunction than those in patients without organ dysfunction (P ＜0.05).Conclusions In AP patients,serum PCT and HMGB1 levels were significantly increased,and they were positively correlated with disease severity.These results suggest that PCT and HMGB1 may act as potential serum markers for AP severity evaluation.
