Methods 100 patients with osteoarthritis of knee joint treated in Xinchang people's hospital from February 2015 to May 2017 were selected and randomly divided into the control group and the experimental group, with 50 patients in each group. The control group were treated with oral glucosamine capsules in the treatment of the experimental group, Cervus and Cucumis Polypeptide for Injection palliative treatment, 250 mL saline plus 25g guguatiquwu, oral Nimeilishu capsule. The treatment time of the 2 groups was one month. The therapeutic effects of the experimental group and the control group were compared and analyzed. Results After the corresponding treatment, 4 patients in the experimental group were invalid, 20 cases were effective, and 26 cases were effective. In the control group, 13 patients were ineffective. The effective rate of the experimental group was 92％, which was significantly higher than that of the control group (P<0.05). The IL-1 of the knee joint fluid in the experimental group was (8.01±1.72), and the IL-1 of the knee fluid in the control group was (7.08±0.97). The level of IL-1 in the knee joint fluid of the experimental group was significantly higher than that of the control group, with statistical difference (P<0.05). Conclusion Cervus and Cucumis Polypeptide for Injection is effective in the treatment of osteoarthritis of the knee, and can significantly improve the efficiency of treatment,.

Objective To study the differences in the inclination of lower incisors among the female patients with beautiful profiles in different vertical skeletal types so as to provide the clinical treatment design for a certain guiding. Methods 137 cephalometric films of female patients with beautiful profiles were selected and divided into three groups based on the vertical facial types(∠SNMP):small degree(n = 31),average degree(n = 89) and larger degree groups(n=17). The angles of∠L1/MP and∠L1/A-Pog were measured and treated with covari-ance analysis for detecting the differences between the groups. Results The index of L1-MP(°)was the smallest in the larger degree group,the largest in the small degree group and average in the average group,with significant differences between the three groups(F = 17.38,P < 0.001). There was no significant differences in ∠L1/A-Pog (°)(F=2.61,P>0.05). Conclusion Lower incisors have compensatory inclined lingually in the group of higher mandible angle,but labially in the group of lower mandible angle.

Objective To compare the clinical outcomes of Bryan disc replacement with anterior cervical discectomy and fusion (ACDF) in patients with cervical spondylopathy. Methods Sixteen patients underwent Bryan cervical disc replacement (A group), and 35 patients underwent traditional ACDF (B group) were included in the study. Patients were followed up at regular intervals. The JOA score, SF-36, neck disability index (NDI) score and the dynamic flexion-extension radiographs were used to evaluated the oucomes.Results All the patients were followed up for more than 6 years (mean, 73.5 months). There were no severe adverse events in both groups. In A group, there were no differences between postoperative and preoperative mobility of surgical segments (P＞0.05). All patients obtained bone fusions 6 month after surgery in group B.In both groups, the clinical symptoms relieved obviously after surgery. The postoperative scores of the JOA,SF-36 and NDI significantly improved compared with those of preoperative ones (P＜0.05). In B group, range of motion (ROM) was significantly decreased postoperatively (P ＜0.01); in A group, there were no significant differences between postoperative and preoperative ROM (P＞0.05). The difference between two groups regarding ROM was noted (P＜0.05). Conclusion The mid-term outcomes of Bryan cervical arthroplasty are satisfied. And the cervical arthroplasty which can maintain the mobility of the segment, and decrease the incidence of the postoperative neck axial symptoms is a viable alternative to cervical spondylopathy.

As an important member of tool enzymes, exonuclease is a kind of hydrolytic enzymes without strict base sequence dependent. In recent years, by taking advantage of different hydrolysis ways of exonuclease and nanotechnology, cycle effect of enzyme digestion, aptamer, non Watson-Crick base pairing system by metal ions, fluorescent nucleic acid probes, electrochemical methods etc. , a series of exonuclease-assisted signal amplification strategies have been developed, which played a very key role in improving the sensitivity of detection methods. Therefore, exonuclease has been widely used in high sensitive detection of nucleic acids, proteins, ions, small molecules and so on. To understand it better and apply it well in the future, the application progress of exonuclease-assisted signal amplification strategies in biochemical analysis has been summarized in this review.

AIM: Peripheral blood mononuclear cells (PBMC) were cultured in vitro to study the effect of gossypol, a polyphenolic antifertility agent, on the activation of normal human T cells. METHODS: Double fluorescent staining together with flow cytometry was adopted to analyze the influence of gossypol on expression of the early activation antigen CD69 on T-lymphocytes under stimulation of mitogen or phorbol ester. RESULTS: Analysis of T cell activation in vitro revealed that preincubation of PBMC with 100 ?mol/L gossypol could completely inhibit the expression of early activation marker CD69 on CD3 + T cells in response to 10 mg/L PHA, and block T cell activation by 10 -7 mol/L PDB as well. The suppression of CD69 expression was dose-dependent and IC 50 of gossypol on PDB and PHA were (35 7?2 9) ?mol/L and (32 8?1.5) ?mol/L( ?s ), respectively. Besides, gossypol had similar inhibitory effect on CD69 expression of CD3 - lymphocytes. However, it did not have any significant effect on T cell surface molecule CD3 down-regulation. CONCLUSION: Gossypol could inhibit T cell activation in vitro in response to polyclonal activators, both PHA and PDB, suggesting that its action site may be at PKC or its downstream and that gossypol possessed potential immuno-regulatory effect.
