ObjectiveAssess the efficacy of repetitive transcranial magnetic stimulation (rTMS) in the treatment of schizophrenia and its social function .Methods 156 patients with schizophrenia were randomly assigned to a real rTMS treatment group (n=78) or a sham rTMS treatment group(n=78) ,each patient in the real rTMS group received 20 rTMS sessions over 4 weeks .Efficacy was evaluated using the Positive and Negative Syndrome Scale (PANSS) at baseline and at 4 weeks .Social function was evaluated u-sing the Personal and Social Performance Scale(PSP) at baseline and at 4 weeks .Results The study group is better than the control group in PANSS total and negative symptoms and PSP total after treatment (P<0 .05) .There is not serious adverse reactions in the treatment .Conclusion rTMS can reduce the negative symptoms and improve social function in schizophrenia with high safety .

Objective To investigate the role of Th17 cells in chronic myeloid leukemia (CML) pathogenesis. Methods 33 CML patients [15 newly diagnosed (ND)- and 18 chronic-phase (CP)- CML patients] and 15 healthy controls were enrolled. The percentage of Th17 cells in the peripheral blood (PB) of CML and controls were evaluated by flow cytometry. RORC mRNA expressions were examined by real-time quantitative reverse transcription-polymerase chain reaction (RT-PCR). The levels of IL-17 in PB of CML and controls were measured by enzyme-linked immunoadsorbent assay (ELISA). The relationships between Th17 cells and clinical characteristics in CML were analyzed. Results The percentage of Th17 cells in PB of ND-CML patients [(0.71±0.41) %] was significantly lower than that of CP-CML patients [(4.08±0.74) %, P<0.05] and healthy controls [(3.18±1.32) %, P<0.05]. The mRNA level of RORC in PB of ND-CML patients (0.043 3±0.040 5) was significantly decreased compared with that in CP-CML patients (0.086 1±0.052 3, P<0.05) and healthy controls (0.091 0±0.058 4, P<0.05). The levels of IL-17 in PB of ND-CML patients [(1.43±0.22) pg/ml] and CP-CML patients [(1.36±0.19) pg/ml] were slightly higher than that of healthy controls [(1.23±0.14) pg/ml, P< 0.05]. The percentage of Th17 cells had significantly negative correlations with white blood cell counts in PB or bcr-abl (IS). Conclusion Th17 cells may play an important role in CML pathogenesis, which has potential implication for immunotherapy of this malignancy.

Objective To explore the expression of pituitary tumor transforming gene (PTTG) and c-myc gene in patients with non-Hodgkin lymphoma (NHL),its relationship with NHL and its clinical significance.Methods PTTG mRNA and c-myc mRNA levels in bone marrow mononuclear cell (BMMNC) isolated from 38 NHL patients and 10 chronic lymphadenitis patients were quantified by reverse transcriptionpolymerase chain reaction (RT-PCR).Results mRNA expression of PTTG and c-myc gene in BMMNC was significantly higher in NHL patients than those in normal controls (PTTG:0.567 7±0.270 7 vs 0.071 2± 0.020 1,t =4.706,P ＜ 0.05; c-myc:0.352 6±0.185 4 vs 0.107 3±0.043 5,t =3.303,P =0.002).The expression of PTTG and c-myc gene in peripheral T cell lymphoma and diffuse large B cell lymphoma showed no significant difference (PTTG:0.556 8±0.211 3 vs 0.602 8±0.244 6,t =0.640,P =0.527; c-myc:0.350 1± 0.177 6 vs 0.361 0±0.190 2,t =0.302,P =0.765).Both expression of PTTG and c-myc were positively related to NHL clinical stage and IPI.Expression of PTTG mRNA was positively related to the expression of c-myc mRNA.Conclusion There was overexpression of PTTG and c-myc in NHL,which indicates that PTTG might be involved in tumorigenesis of NHL through direct or indirect activation of c-myc oncogene.

Objective To investigate the effect of arthroscopic debridement and meniscectomy in treatment of moderate or severe meniscus injury combined with knee osteoarthritis in early or middle stage. Methods 156 cases diagnosed with moderate or severe meniscus injury combined with knee osteoarthritis in early or middle stage were collected from October 2011 to October 2014. Lysholm knee score and preoperative examinations such as anteroposterior, lateral, axial radiographs, the standing full leg length X-ray film and MRI scan of the knee were recommended to definitively understand the osteoarthritis staging and meniscus injury grading. All patients were treated with arthroscopic debridement and meniscectomy. After operation, physical rehabilitation exercises and regular clinical follow-up were carried out as planned. The Lysholm knee score data from preoperation and terminal follow-up was statistical analyzed. Results No patient experienced any perioperative and postoperative complications. Statistical analysis showed that the Lysholm knee score of postoperation was significantly higher than that of preoperation [(87.3 ± 7.9) vs (67.5 ± 4.9), P < 0.05). Conclusion Arthroscopic debridement and meniscectomy in treatment of moderate or severe meniscus injury combined with knee osteoarthritis in early or middle stage, gains beneficial effects for its minimal invasion and quick recovery.

Objective To evaluate the efficacy and safety of DA-EPOCH-R protocol for patients with B-cell non-hodgkin lymphoma (NHL). Methods 43 patients with B-cell NHL received DA-EPOCH-R protocol, and their efficacy and adverse reactions were analyzed. Results 43 patients received a total of 203 cycles of chemotherapy and the median chemotherapy cycle was 6 (2ˉ8 cycles). 32 patients (74.4%) achieved complete remission (CR) after 2ˉ4 cycles of chemotherapy. A further analysis found that age ≤60 years and>60 years, stageⅠ/Ⅱand stageⅢ/Ⅳ, germinal center B-cell (GCB), non-GCB, double expression lymphoma (DEL) and non-DEL patients had no significant differences (P> 0.05). With a median follow-up of 40 months (9ˉ62 mouths), the overall survival (OS) rate of 1-year and 3-year was 97.6 % and 92.8 % respectively. The major toxicity of DA-EPOCH-R protocol was hematologic toxicity. Other toxicities were mild, and no treatment-related deaths occurred. At the end of follow-up, no secondary tumors were found. Conclusions DA-EPOCH-R protocol is an effective and safe protocol for patients with NHL. The result shows that the curative effect of patients in stageⅢandⅣis similar to the patients in stageⅠandⅡ.

Objective:To understand the reasons for non-adherence of pulmonary rehabilitation exercise in patients with acute exacerbation of COPD, and in order to provide theoretical and practical basis for improving patient adherence.Methods:Using qualitative phenomenological research methods, eighteen patients of non-adherence with exercise were conducted deeply semi-structured interviews, and the Colaizzi analysis was used for data analysis and extracting themes.Results:Seven themes were extracted: effect of subjective and objective symptoms, limited by comorbidity, negative mood disturbance, lack of perception effect, material environment in ward, cultural environment in ward and inappropriate form of exercise.Conclusions:Health care providers should value these obstacles and implement targeted measures, in order to achieve the goal of improving exercise adherence, so that more patients would complete pulmonary rehabilitation exercise.
