Objective To investigate and analyze the health care seeking behavior,financial burden and relative factors of patients with rheumatic diseases in Fujian Province.Methods Patients diagnosed with rheumatic diseases were investigated in Fujian Provincial Hospital from December 2013 to February 2014,including demographic data,health care seeking behavior and financial burden.Relevant factors were analyzed by Logistic regression.Results ① In this study,474 patients were enrolled.The ratio of male to female was 1∶2.38.② At the onset of symptoms,51.9％(246 cases) of patients visited a doctor as soon as possible,and 36.1％(171 cases) of them went to hospital within a month after disease onset.③ 74.1％(351 cases) of patients could adhere to medication regimen prescribed by doctors,and the most common reason for stopping medication was symptoms relieved (33.3％,41 cases).④ 63.1％(299 cases) of patients learned about the knowledge of rheumatic diseases from hospitals and doctors.⑤ 34.2％(162 cases) of patients spent 1 000-5 000 yuan every month on treatment.⑥ Insurance type could affect the time of first visit to hospital (P=0.004),while income and cost of therapy might impact patients' compliance (P=0.013,P=0.004).Conclusion Most patients will go to hospital as soon as possible and adhere to treatment.Economic situation is the main factor influencing health care seeking behavior of patients with rheumatic diseases.

Objective To evaluate the anxiety and depression problems in children parents with leukemia, as well as the problems' influence to the psychosocial characteristics of leukemia children.Methods Twenty long-term survivors of childhood leukemia (group A), thirty children newly diagnosed as leukemia (group B) and fifty age-matched healthy controls (group C) completed the questionnaires allowing assessment of symptoms associated with anxiety, depression and self-concept. At the same time, the anxiety and depression in the parents of children with leukemia were also measured using SAS and SDS. Results The anxiety and depression scores of the parents in study group (48.56±9.23, 51.86±9.53) were much higher than that in normal population (37.23±12.59, 41.88±10.57) (P = 0.000, 0.000, respectively), the positive rate of anxiety and depression symptoms among group B was significantly higher than that among group A (60.0 % vs 25.0 %, 46.7 % vs 20.0 %; P <0.05, respectively). There was a significant positive relation between the depression and anxiety scores in the parents of children with leukemia(r =0.947, P =0.0000). Group A scored significantly higher on subscales of somatization/panic (6.11 ±4.36), generalized anxiety (5.72±4.56),social phobia (7.67±4.19) and the total scale (25.8±13.98) than group C (the score was 3.68±3.39, 2.54±2.99,4.24±2.88 and 15.9±10.52, respectively) (P<0.05, respectively), group B scored significantly higher on subscales of social phobia (6.03 ±2.16) than group C (4.24±2.88) (P =0.016). There was a significantly positive relation between the depression score in children with leukemia and the anxiety (r = 0.309, P = 0.029) & depression(r = 0.342, P = 0.015) scores in their parents. Group A scored significantly higher on the total score of self-concept(60.8±6.25) as well as the subscales of happiness(7.95±1.32) than group G (64.48±7.89 vs 8.64±1.19) (P =0.039, 0.026, respectively); and group B scored significantly higher on subscales of behavior (12.47±1.25), intelligence(10.80±2.12), physical appearance and attributes (8.40±2.66), anxiety (9.93±1.29) and the total scale (59.83±5.87) than group C (14.00±2.17, 12.60±2.96, 9.64±2.30, 11.38+2.18, 64.48±7.89) (P <0.05, respectively). There was a significantly positive relation between the score of gregarization subscale in leukemic children and the anxiety score in their parents (r = 0.337, P = 0.017). Conclusion The findings of our studies have suggested that the parents of children with leukemia are at risk for psychological difficulties, and which have a great influence on the psychological health of their children.

Objective To analyze the psychological condition of postgraduates in clinical hos-pitals of colleges and universities before and after the implementation of psychological mentor scheme so as to evaluate the effect. Methods Quantitative questionnaire (SCL-90 scale) and qualitative fo-cus interview were used to compare psychological condition of postgraduates. Totally 182 copies of questionnaires were sent to two hospitals (A and B) respectively. Then, psychological mentor scheme was carried out in A hospital. Afterwards, 206 and 140 copies of questionnaires were sent again to the hospitals respectively to compare the results. Eight student psychological consultants, 12 postgraduates and 5 postgraduate management staff were enrolled in qualitative focus interview. Excell2003 software was adopted to establish the database and SPSS 11.0 software was used for statistical analysis. Descrip-tive analysis, frequency analysis, t test, chi-square test and variance analysis were adopted for data analysis. P<0.05 signifies for statistically significant difference. Results Mental health status of both groups was better than the national level before the implementation (total SCL score: A hospital=118 . 08 ±36.20; B hospital =100.33 ±22.90). However, SCL-90 score of A hospital was decreased (total SCL score: 102.58 ±25.23) and that of B hospital (total SCL score:134.01 ±38.92) was in-creased (part of items higher than the adult national norm) at one year after conducting psychological mentor scheme. Conclusions Psychological mentor scheme can effectively relieve stress and interper-sonal stress so as to reduce the general psychological problems and can help to improve mental health of the students.

BACKGROUND:Animal model of infection is established using bioluminescent gene-labeled bacteria, which stimulate local environment of spine infection and reveal the pathophysiological mechanism of spine infection.
OBJECTIVE:To evaluate the feasibility and safety of anterior one-stage debridement, autogenous iliac bone grafting and titanium plate internal fixation in the management of pyogenic spinal infections in spine.
METHODS:Total y 24 Chinese dogs were adopted in the study to develop a canine model of acute pyogenic spondylodiscitis using a bioluminescent strain of Staphylococcus aureus Xen29. The animal models were detected by X-radiography, CT and MRI examinations. After 4 weeks of modeling, al the animals underwent one-stage debridement, autogenous iliac bone grafting and anterior titanium plate internal fixation. Antibiotics contained Cefazolin and Gentamicin were administrated daily since perioperative period to 4 weeks after surgery. The titanium plate and adjacent vertebra were removed surgical y at various postoperative time points (4, 8, 12, 24 weeks) when the dogs were kil ed. The excised tissues and retrieved implants were cultured with conventional bacteria, bacteria 16S rRNA and specific Nuc gene of Staphylococcus aureus. PCR and bioluminescence imaging technique were used to detect the presence of bacteria.
RESULTS AND CONCLUSION:The surgical wound was healed uneventful y. Gross observation and MRI examination of the specimens showed that there was no abscess formation or signs of infection recurrence. The infection rate was 41.7%(10/24) and 75%(18/24) in the procedure of conventional bacteria and bacteria 16S rRNA cultivation. The results showed that the sensibility of PCR technique used to detect the presence of bacteria by amplifying the highly conservative gene sequence of 16S rRNA was significantly higher than that of conventional bacterial cultivation procedure (P<0.05). The PCR detection of specific Nuc gene of Staphylococcus aureus showed the existence of Staphylococcus aureus (1/24). However, Staphylococcus aureus Xen29 with genetic marker was not detected around the implant by bioluminescence imaging technique (0/24). Al of the results showed that bacterium adhering to prosthesis in vivo is an universal phenomenon. The bacteria identified from prosthesis which was taken during the surgery and the bacteria by which the spine was infected before the surgery was not homologous. The one-stage debridement, autogenous bone grafting and anterior titanium plate internal fixation is safe and effective in the management of pyogenic spinal infections. Using of internal fixator can not lead to recurrence or persistence of infection.

Objective To study the efficacy and safety of four surgical techniques of tuberculosis of lumbosacral junction retrospectively. Methods Between Jul 2001 and Jan 2013, 79 patients with lumbosacral spinal tuberculosis underwent surgery. Antituberculous chemotherapy and nutrition support prior to surgery were used for at least two weeks. 45 patients underwent single stage radical debridement, fusion and anterior instrumentation (A group). 18 patients underwent combined anterior and posterior spinal surgery (AP group), 10 patients underwent transpedicular drainage, posterior instrumentation, and fusion (P group), and 6 patients underwent anterior radical debridement (D group). All the patients were treated by antituberculous chemotherapy for 18 months and followed regularly. The operation duration, blood loss, clinical status, ESR, VAS, ODI, roentgenogram and 3D?CT were concerned to estimate the progress of tuberculosis. Radiographs were analyzed before surgery, immediately after surgery, and at the final follow?up examination to assess the result of anterior fusion and maintenance of correction. Results There was no inju?ry of blood vessel, ureter or cauda equina during surgery. The mean follow?up period was 23 months (range 18-42 months). No obvious loss of deformity correction was observed. There was no recurrence, no tuberculous peritonitis, and no incidence of im?potence or retrograde ejaculation in any of these patients. The average operating duration(min) were 144.31 ± 23.18, 444.72 ± 141.63, 351.50 ± 85.25, 90.00 ± 29.66, respectively; The average blood loss(ml)were 266.67 ± 104.45, 988.99 ± 488.26, 890.00 ± 306.23, 200.00±104.88, respectively; The average Pre?op VAS were 4.71±1.79, 5.22±1.48, 3.30±1.64, 2.50±1.52, respectively;The average last follow?up VAS were 0.89±0.68, 0.90±0.74, 1.00±0.63, respectively; The average Pre?op ODI(%)were 29.64± 7.85, 32.17±7.59, 28.20±4.26, 20.67±4.63, respectively; The average last follow?up ODI(%)were 5.09±3.59, 4.78±3.78, 4.80± 3.39, 4.00 ± 1.18, respectively; The average Pre?op lumbosacral angle(°)were 20.61 ± 4.92, 23.78 ± 5.84, 25.10 ± 4.28, 21.67 ± 4.27, respectively; The average Post?op lumbosacral angle were 27.17±3.66, 30.56±5.31, 32.10±4.01, 24.83±2.32, respectively;The average last follow?up lumbosacral angle were 23.89 ± 3.12, 27.00 ± 5.46, 29.00 ± 4.85, 23.33 ± 2.50, respectively. Conclu?sion Single stage anterior interbody fusion with anterior instrumentation worked effectively to stabilize lumbosacral junction (less invasive, short surgical duration, no injury of posterior column). Anterior interbody fusion combined with posterior instrumentation was recommended for patients with extensive bone defect and low iliocava junction.

Objective To analyse the phenotypes of the drug?resistant tuberculosis, and investigate the outcomes of the individualize surgery and chemotherapy for these patients. Methods From January 2009 to June 2012, we retrospectively ana?lyzed 49 patients with drug?resistant tuberculosis spondylitis admitted in Southwest Hospital. 33 were initial cases and 16 were re?curring cases. All the 49 patients received individualized open operation or CT?guided percutaneous drainage and local chemother?apy depending on the characteristics of the focus. Individualized chemotherapy regimens were tailored for all patients according to the drug?resistant spectrum and all patients were followed up successfully at least 24 months. All the clinical data were collected and analyzed by statistical methods. Results Among the 49 patients, 14 were monoresistance tuberculosis, 11 were polyresis?tance tuberculosis, and 24 cases were multi?drug resistant tuberculosis. Frequence of the drug?restistance from high to low was Iso?niazid, Rifampicin, Streptomycin, Levofloxacin, Dipasic/Rifapentine, Ethambutol, Protionamide, Capreomycin, Paza?aminosalicy?late, and Amikacin. 43 patients received open operation and 6 patients received CT?guided percutaneous drainage and local che?motherapy. Time of the percutaneous drainage was (48±11) days (39-60 days), and all patients received Individualized chemother?apy with an average of (29.5±2.5) months (24-36 months) postoperatively. At the last follow?up, all patients had remarkable pain remission, 44 patients with paraplegia got slight or remarkable recovery and 17 patients with kyphosis got significant correction. Conclusion The main drug?resistant spectrums are Isoniazid、Rifampicin、Streptomycin、Levofloxacin. The individualized sur?gery combined with individualized chemotherapy made according to the drug?resistance is a feasible treatment for the drug?resis?tant tuberculosis especially the multi?drug resistant tuberculosis.

6.2 mmol/L) who underwent renal transplantation accepted pravastatin therapy 10 mg once evening for 8 weeks. Total cholesterol(TC),low-density lipoprotein-cholesterol (LDL-C),high-density lipoprotein-cholesterol (HDL-C),triglyceride(TG),endothelin(ET) and nitrous oxide(NO) were measured before and after pravastatin therapy. The endothelium-dependent relaxing function was measured before and post pravastatin therapy by high-resolution ultrasound. Thirty people with normal blood cholesterol accepted same examination as control. Results The level of ET in renal transplantation group was significantly higher than that of control group,and the level of NO in renal transplantation group was significantly lower than that of control group. After 8 week′s therapy,the level of NO rose significantly,and the level of ET,TC,LDL-C,TG decreased significantly. The level of HDL-C increased but there was no significant difference between two groups. Flow-mediated vasodilations were improved after pravastatin therapy,while the level in transplantation group was lower than that of control group. Conclusion Pravastatin is effective in treatment of dyslipidemia after renal transplantation,which can improve the endothelium-dependent vasodilation.

Objective To compare the serum peptidome spectrum between nephrotic syndrome patients and normal controls, and to search for their variations. Methods The serum peptide profiling was determined by ClinProt magnetic bead enrichment and matrix assisted laser desorption ionisation time-of-flight mass spectrometry (MALDI-TOF MS) in 17 mesangial proliferative glomerulonephritis (MsPGN) patients, 12 minimal change nephrotic syndrome (MCNS) patients, 10 membranous nephropathy (MN) patients, 10 focal segmental glomerulosclerosis (FSGS) patients, and 10 healthy volunteers. Results 5 differentially expressed polypeptides were screened out between MsPGN and normal controls (15.28±7.61, P＜0.01). 7 differentially expressed polypeptides were screened out between MCNS and normal controls (2.16±1.59, P＜0.01). 6 differential expressed polypeptides were screened out between MN and normal controls (35.48±13.71, P＜0.01). 5 differential expressed polypeptides were screened out between FSGS and normal controls (18.06±8.07, P＜0.05). The statistical significance was set at P＜0.05. A Genetic Algorithm was used to set up the classification model between patients and normal controls. The model separated MsPGN, MCNS, MN and FSGS group from normal controls with a cross validation of 96.18%, 100%, 98.53% and 94.12%, respectively. The recognition capabilities were 100%. Conclusions The study established the serum peptidome spectrum for nephrotic syndrome by proteomic technology, and provided a new viewpoint to better understand the pathogenesis of nephrotic syndrome.
