Objective To investigate the expression levels of Interleukin(IL)?6 and matrix metalloproteinases(MMP)?13 in synovial fluid by in?vigorating kidney and activating blood formulae in treating rabbit knee osteoarthritis model. Methods A total of 30 New Zealand rabbit were ran?domly divided into blank group,model group,invigorating kidney group,activating blood group and invigorating kidney and activating blood group. Rabbits model with knee osteoarthritis were established by improved Hulth method. To give corresponding respectively the medicinal broth,model group was given saline,knee joint synovial fluid was collected after 4,8 and 12 weeks. Enzyme linked immunosorbent assay(ELISA)was used to measure the levels of IL?6 and MMP?13. Results The levels of IL?6 in rabbit knee osteoarthritis were obviously higher than that of normal control group at both 4 weeks and 8 weeks(P<0.001). But there was no statistical difference on the levels of IL?6 compared with controls in 12 weeks. In addition,the level of MMP?13 at 4 weeks,8 weeks and 12 weeks were significantly higher than the blank control group(P<0.001). After 8 weeks of Chinese medicine administration,the levels of IL?6 in synovial fluid were significantly decreased in invigorating kidney group,activating blood group and invigorating kidney and activating blood group(P<0.001),but there was no statistical difference among groups in 12 weeks. The MMP?13 levels of synovial fluid was significantly lower than the model group(P<0.001). Conclusion Our results indicate that IL?6 and MMP?13 par?ticipate in the pathological development of the rabbit knee osteoarthritis. Invigorating kidney and activating blood formulae could reduce the expres?sion of IL?6 and MMP?13 and alleviate osteoarthritis progression,and which is superior to the pure invigorating kidney formulae and activating blood formulae.

Objective To investigate and analyze cognitive similarities and differences of nurses factors that lead to the tense nurse-patient relationship from both attitudes of nurses and patients. Methods By using the method of questionnaire, 284 nurses and 305 patients were investigated respectively in a top'three hospital of a city. Results There was a significant difference in cognitive scores of nurses factors that lead to the tense nurse- patient relationship (P < 0.01), patients' scores were (3.90±0.47) points which were higher than (3.52±0.35) points of the nurses′. In dimensions of prioritization, both nurses and patients believed that technical ability, professional knowledge and service attitude were the main factors leading to the tense relationship between nurses and patients. While nurses held that communication ability was more important, patients held that the nurse′s own personality was more important. Conclusions There are similarities and differences of attitudes to nurs's factors between nurses and patients regarding tension in nurse- patient relationship. The tense relationship between nurses and patients is affected to a great extent by nurses' professional knowledge, technical ability and service attitude. Managers should objectively evaluate and fully pay attention to cognitive similarities and differences of both sides, strengthen nurses′theoretical knowledge and clinical skills training, improve service attitude, and develop good character,in order to provide high quality nursing service for patients.

Objective To observe the blood flow changes of left ventricular cavity and quantify the energy loss (EL) and circulation of left ventricular during systole and diastole in patients with dilated cardiomyopathy(DCM) via vector flow mapping(VFM).Methods Thirty-six healthy volunteers and 32DCM patients were enrolled.According to the severity of mitral regurgitation(MR),DCM patients were divided into two groups.The quantitative parameters,including average energy loss(EL-base,EL mid,EL-apex) and circulation (vortex quantity,vortex area,circulation) were measured in the different periods of VFM imaging mode in apical four-chamber view,apical three-chamber view and apical two-chamber view respectively.The difference of parameters was evaluated between different groups during the different periods.The early transmitral valve blood flow velocity E,the late transmitral valve blood flow velocity A,the ratio of early transmitral valve blood flow velocity to the early diastolic mitral valve velocity E/e,the ratio of early transmitral valve blood flow velocity to the late transmitral valve blood flow velocity E/A and Tei index were derived via dual-Doppler imaging technology.Meanwhile,the correlation between VFM parameters with E,A,E/A,E/e or Tei index was also analyzed.Results ①The level of EL were decreased significantly among EL-mid and EL-apex during early diastole,EL-mid during mid-systole,EL-mid and EL-apex during late-systole (P <0.05),when compared with the control group.The vortex quantity,vortex area and circulation during early diastole and the vortex area and circulation during atrial contraction period were significantly different between two groups (all P < 0.05).As for mid-diastole,only vortex area showed significant difference (P <0).01).(②) When compared with different grades of MR in DCM patients,the level of all segments EL during diastole and EL-base during systole increased with severity of MR(P <0.05).The circulation during diastole also increased with the severity of MR(P <0.05).③The vortex area and circulation had positive correlation with E/e during diastole in all subjects(all P <0.05).The vortex area during atrial contraction period and early diastole had positive correlation with E/A and Tei index in all subjects(r =0.630,0.345,0.468,0.316,0.663,0.264,respectively,allP <0.01).EL-mid during late-systole were negatively correlated with LV end diastolic volume,end systolic volume,but positively correlated with ejection fraction in all subjects(r =0.335,-0.312,0.340,respectively,all P <0.05).While,there was positive correlation between E/A with the basal segment of mid-diastole(r =0.376,P <0.01).Conclusions The visualization of hydromechanics inside the heart of DCM patients could be directly accomplished by VFM,which can provide a new method for diagnosis and evaluation of DCM.

Objective To observe multiple metabolic changes within one year after Roux-en-Y gastric bypass (RYGB) surgery in obese patients with type 2 diabetes mellitus, and to evaluate the index of the gastric bypass surgery and the determination of applicable population. Methods The clinical and laboratory data before and after surgery in 112 patients diagnosed as type 2 diabetes mellitus by RYGB were included in this study. According to BMI, these patients were divided into two groups: normal group (≤ 25kg/m2), and the overweight group (> 25 kg/m2). The physiologic and biochemical indexes of the patients were followed up at 1, 3, 6, 12 months, respectively. The statistical analysis was performed by SPSS17.0 software. Results Compared with the preoperative period, the levels of HbA1c and HOMA-IR in the postoperative period were significantly increased in the two groups. Principal component analysis showed that the postoperatively contributions of BMI and HbA1c in 6 months was bigger than that of the other indexes, while HOMA-β, HOMA-IR had larger contributions after 6-month postoperative period. Conclusion Various metabolic indexes in patients with type 2 diabetes improve significantly within one year after surgery, and the complete remission rate is gradually increased. The indexes including weight, blood glucose, serum lipids, HOMA-βand HOMA-IR in overweight and obese group have more significant improvements than those in normal group. Obese patients are more appropriate for the surgical treatment. The indexes, such as BMI, HbA1c,HOMA-βand HOMA-IR, should help to evaluate the operating effectiveness and preoperative indications.
