186 serum samples from 81 patients with gastric cancer were determined for circulatingimmune complexe (CIC) by using the polyethylene glycol turbidity assay. Compared with 105healthy blood donors, the mean value of CIC were significantly increased in pretreatment pati-ents (47.46?24.52vs.27.67?12.09), and the corresponding figures for stage Ⅰ+Ⅱ, Ⅲ and stage Ⅳpatients were 38.60?14.24, 42.04?13. 18 and 54.31?29. 15 respectively. The incidence of positivityof CIC in pretreatment patients was 32.1%. The mean value of CIC is significantlyhigher in patients whose disease could not be treated with radical surgery than in patientswhose disease could.CIC levels increased significantly during 11～45 days after radical operation.CIC levels were positive correlated with levels of serum IgA, IgM, C_3, and negative corre-lated with the rate of lymphocyte transformation. The patients found positive for ANA hadhigher incidence of positivity of CIC than those found negative for ANA.The clinical signifi-cance of CIC in patients with gastric cancer was also discussed.

ObjectiveTo compare the clinical effect of posterior circumferential fusion with versus without intertransverse process fusion on lumbar instability in aged patients. MethodsThe elderly with lumbar instability were treated with the posterior instrumented circumferential fusion technique in 80 cases. Among 58 patients followed up for at least 2 years, 28 cases (group A)underwent posterior circumferential fusion with intertransverse process, while 30 cases (group B)without intertransverse process. X-ray examination was used before and 1, 3, 6, 12 and 24 months after operation to evaluate the fusion condition of the bone graft, and visul analogue scale (VAS) and Oswestry disability index (ODI) questionnaire were applied to assess the pain of center back and leg,and the conventional activity.ResultsThe operation time and blood loss were more in group A[(185.3±56.6) min and (376.3±92.9) m1] than in group B [(146.4±46.3) min and (234.3±64.5)ml (t=12.37, 37.49, P＜0.01)]. All the 58 cases were followed for at least 2 years. The 27 cases (96.4％) of group A and 28 cases (93.3％) of group B got bone fusion (x2 =0.004, P＞0.05).There were marked differences in the VAS of center back at 1 and 3 months after operation between the 2 groups (t=3.178, 2.158, both P＜0.05), while no difference at the other 3 time point. VAS about the leg pain and the ODI showed no differences between group A and B after operation (all P＞0.05). ConclusionsFor the lumbar instability in the elderly, the posterior circumferential fusion with or without intertransverse process fusion can achieve a similar high rate of fusion and satisfactory clinical results,andtheposteriorcircumferentialfusionwithoutintertranaverseprocess is recommended for less trauma.

Fructose-1, 6-bisphosphatase (FBPase), a rate-limiting enzyme involved in the pathway of gluconeogenesis, can catalyze the hydrolysis of fructose-1, 6-bisphosphate to fructose-6-phosphate. Upon inhibiting the activity of FBPase, the production of endogenous glucose can be decreased and the level of blood glucose lowered. Therefore, inhibitors of FBPase are expected to be novel potential therapeutics for the treatment of type II diabetes. Recent research efforts were reviewed in the field of developing allosteric inhibitors interacting with the AMP binding site of FBPase.

Objective To investigate the clinical manifestations, imaging features, diagnosis and management of pulmonary mycosis.Methods Fifty-four patients were identified with pulmonary mycosis by pathological examination in our hospital from January 2002 to June 2008. Data of clinical manifestations, imaging features, diagnosis and management were retrospectively reviewed.Results Of the 54 cases, 30 (55.6%) were pulmonary aspergillosis, 15 (27.8%) were pulmonary cryptococcosis. Underlying disease was reported in 42 of 54 (77.8%) cases. The diagnosis of all the patients was confirmed by pathological exami-nation. Lung or bronchi tissue was obtained by operation in 30 (55.6%) cases, by bronchofibroscope in 12 (22.2%) cases, by CT-guided percutaneous needle biopsy in 9 (16.7%) cases, and by lymphoid node biopsy in 4 cases. Main symptoms included cough (41, 75.9%), expectoration (30, 55.6%), hemoptysis (20, 37.0%), fever (16, 29.6%), and asymptomatic (6, 11.1%). The X-ray and chest CT showed masses or nodule lesions (41, 75.9%), patchy lesions (8, 14.8%), cavity (12, 22.2%), diffuse milliary nodules (1 case). Bilateral lungs were involved in 7 cases (13.0%);right lung alone in 26 cases (48.1%);left lung alone in 21 cases (38.9%). Among the 54 cases, 41 (75.9%) were misdiagnosed before pathological examination. Thirty (55.6%) cases underwent surgical resection of pulmonary lesions. One patient suffered from cryptococcal meningitis after operation. Twenty (37.0%) patients received systemic anti-fugal therapy. Cure or significant improvement was found in 16 cases. Conclusions The most frequently isolated fungi were Aspergillus, followed by Cryptococcus. Final diagnosis is mainly dependent on pathological examination. Clinical manifestations, imaging features, diagnostic procedures and management are different due to the difference of pathogenic fungi. Satisfactory Results can be obtained by anti-fungal therapy combined with surgical management.

Objective To describe the characteristics of organizational culture,to identify the level of quality of work life,and to explore the relationship between each dimension of organizational culture and quality of work life among nurses in tertiary hospitals in Yunnan Province,China.Methods The subjects were 416 nurses from six tertiary hospitals in Yunnan Province.Research instruments were the Organizational Culture Profile (OCP) and the Quality of Work Life Scale (QWLS).Results The results of this study showed that four dimensions of organizational culture including competitiveness (3.56 ± 0.49);performance orientation (4.08 ± 0.22);stability (3.68 ± 0.43) and social responsibility (3.95 ± 0.37) were prominent.The other 3 dimensions,namely supportiveness (3.19 ± 0.79);innovation (3.21 ±.0.62) and emphasis on rewards were perceived (2.42 ± 0.79) as less prominent.The overall mean score of quality of work life was at a moderate level (57.46 ± 15.17).Conclusion There are positive significant correlation between each dimension of organizational culture and quality of work life (P＜ 0.01).Improvement of organizational culture can enhance quality of work life among nurses,and then guarantee the nursing quality.

Objective The aim of this study was to assess the value of △Np63α in predicting tumor recurrence after curative resection in esophageal squamous cell carcinoma (ESCC) patients.Methods We analyzed △Np63α protein cxpression in 304 clinicopathologically characterized ESCC cases by immunohistochemistry.Results We found △Np63α expression was positive in 122 (40％) of 304 cases.△Np63α expression was higher in the cancer tissue than in non-tumorous control tissue at protein level(P =0.034).There was a significant difference of △Np63α expression in patients categorized according to invasive depth (P =0.001),tumor position (P =0.001) and lymph nodes metastasis condition (P =0.001).Multivariate analyses showed that △Np63α was an independent prognostic marker for ESCC recurrence.Conclusion △Np63α is associated with outcome of ESCC and can be a novel predictor for poor prognosis of ESCC patients after curative resection.

【Objective】To study the effect of light weight-bearing activity on postmenopausal osteoporosis.【Methods】36 female rats were randomly divided into 3 groups:① Sham,② Ovx (ovarietomized),③ Ovx+Im (ovarietomized and immobilized).All the group's maintained daily activity.And because of being immobilized,the right hind limbs of the third group lacked weight-bearing activity.12 weeks after ovarietomy,the BMD (bone mineral density),histomorphometry and biomechanics of the right femurs of rats were measured and analyzed.【Results】Comparing with the Sham group,the Ovx group's right femurs were manifested with the decrease of BMD,TBV (trabecular bone volume),MTT(mean trabecular thickness) and MCT(mean cortex thickness),while the increase of RS(resorption surface) and OS(osteotoid surface).Meanwhile their biomechanic nature declined.But statistically the BMD,MCT and the criteria of mechanical strength were not significant decrease.Otherwise,the Ovx+Im group's right femurs showed more apparent decrease of BMD,TBV,MTT and MCT.And the biomechanic nature was worse.Comparing with the Sham group,the BMD,MCT and the criteria of mechanical strength of the Ovx+Im group were statistically significant decreased.【Conclusion】If maintaining light weight-bearing activity,the ovarietomized rats were able to maintain relatively better bone quality.A lack of light weight-bearing activity wouldcause thedecline of bone quality.Thusthestudy suggested light weight-bearing activity was significantly effective on the prevention and treatment of postmenopausal osteoporosis.

ObjectiveTo establish a new biomechanical test for evaluating biomechanical properties of femoral metaphysis in ovariectomized rats.MethodsTwenty-five-month-old female Sprague-Dawley rats were randomly divided into ovariectomized (OVX) group and the sham-operated (Sham) group (n=10).Twelve weeks after operation,femur BMD and histomorphometry of distal femur were detected.Furthermore,femur biomechanical parameters were determined by diaphysis three-point bending test and a new designed metaphysis bending test.The relationships between the biomechanical parameters and BMD or bone histomorphometry were assessed with Pearson correlations.ResultsThe femur BMD,bone histomorphometrical indexes(％Th.Ar,Tb.N,Tb.Th),and biomechanical parameters(maximum load,yield load and stiffness) of OVX group significantly decreased compared with Sham group.In metaphysis bending test,the mean difference of the maximum load(Fmax),yield load(Fy) between group OVX and Sham were significant higher than that in diaphysis three-point bending test.Positive correlations between biomechanical parameters and femur BMD or bone histomorphometry indexes were observed in both the diaphysis bending and metaphysis bending test.The biomechanical parameters in the metaphysis bending test showed stronger correlations with BMD and bone.ConclusionFemur metaphysis bending test could be used to evaluate the biomechanical properties of osteoporosis.When compared with diaphysis bending test,femur metaphysis bending test is more sensitive in evaluating the change of biomechanical properties of femur in osteoporotic rats.

Objective To investigate the potential association between SEPS1 variants and Hashimoto's thyroiditis (HT)in the Chinese Han population and evaulate the effects of SEPS1 haplotypes on the susceptibility to immunity-mediated diseases.Methods We analyzed 7 SNPs with minor allele frequency (MAF)≥0.05 in a cohort of 1013 HT patients and 2998 healthy controls from genetically independent Han Chinese individuals.Single SNP,haplotype and gender-specific associations were performed. Results We found that rs28665122 was significantly associated with HT,and SNP was associated with HT in females.Further haplotypic analysis indicated that a haplotype block (rs2009895-rs28665122)spanning the promoter of SEPS1 gene was highly associated with HT. Additionally,the haplotype CA in the block had an almost 1.5-fold increase in these cases,which remained significantly associated with HT in females.Conclusion SEPS1 plays a role in the pathogenesis and etiology of HT.

Objective To analyze and evaluate the effect of posterior circumferential fusion for treatment of the mechanical instability of lumbar spine, and discuss the relative merits,indications and contraindications in this procedure. Methods Two hundred and two patients with mechanical instability of lumbar spine treated by the posterior instrumented circumferential fusion technique from January 2001 to January 2007. One hundred and thirty-two patients were selected who were treated with only one segment fusion and followed up for at least 1 year, of them 97 patients suffered lumbar spondylolisthesis, 35 patients suffered degenerative lumbar instability. X-ray was used to evaluate the fusion condition of the bone graft, and VAS and ODI questionnaire were applied to assess the pain of back and leg,and the conventional function. Results All patients were followed up for 12-84 months, averaged (43±23) months,125 patients got bone fusion, accounted for 94.7%(125/132). The VAS of low back pain was (6.71 ± 1.31) points before operation, while (3.20 ± 1.14) points after operation (P < 0.05) ,and the VAS of leg pain was (8.33 ± 1.78) points before operation,while (4.31 ± 1.15) points after operation (P< 0.05). The ODI was (68.6 ± 14.7) % before operation, while (13.6 ± 1.5) % after operation (P < 0.05). Conclusions Posterior circumferential fusion is a positive and excellent treatment for the mechanical instability of lumbar spine. With its merits, the high fusion rate and good clinical results can be received.
