Objective To evaluate the association between C-reactive protein (CRP) blood levels and specific survival time of non-small cell lung cancer (NSCLC) patients treated with chemotherapy.Methods Data from 96 advanced (stage ⅢB/Ⅳ) NSCLC patients were analyzed.All patients were divided into two groups based on the enrolled time as follows the initial treatment group (48 cases) and retreatment group (48 cases).According to 0.6 mg/L and 7.3 mg/L of CRP which were the 1/3 and 2/3 of CRP concentrations,respectively,the 96 patients were divided into low,intermediate and high groups.Kaplan-Meier and Cox proportional-hazard models were used to evaluate the relationship between the CRP level and survival time.Results After adjusting for age,sex,smoking history,histological type and stage of lung cancer,a significant relationship between CRP and survival time was observed (P ＜ 0.05).Such significant differences of survival time were also observed in both of the adenocarcinoma (P ＜ 0.001) and squamous with poorly differentiated (P =0.032) subtypes.On stratification analysis by chemotherapy status,the circulating CRP level in retreatment group was correlated well with survival time (P ＜ 0.001).However,the influence of circulating CRP levels on survival time in initial group did not reach statistical significance (P =0.296).For all patients,the hazard ratio with high CRP levels for NSCLC-specific survival was 1.15 (95 ％ CI 0.82-1.61) compared with that of low CRP levels.The hazard ratio for the initial treatment group and retreatment group were 0.52 (95 ％ CI 0.16-1.74) and 1.77 (95 ％ CI 0.73-4.26),respectively.Patients with high circulating CRP level also responded poorly to chemotherapy.Conclusion A high level of circulating CRP is associated with an inferior response and survival outcome in NSCLC patients treated with chemotherapy.

Objective To evaluate the effect of Ganoderma lucidum on drug resistance of the cisplantin-resistant ovarian cancer cell line(A2780CP).Methods The A2780CP cells were randomly divided into control group and test group.The cells in control group and test group were incubated in culture media alone and in culture media containing Ganoderma lucidum 0.5 mg/ml for 48 h respectively.The resistance index(RI) of A2780CP was determined by WST-1 assay.The expression of Akt,Bcl-2 and p53 protein was measured by Western blot.Results The RI was significantly deeressed,the expression of Akt and Bcl-2 protein was down-regulated,while p53 protein expression was up-regulated in test group as compared with control group(P<0.05).Conclusion Ganoderma lueidum can reduce the resistance of A2780 CP cells to cisplantin by down-regulating the expression of Akt and Bcl-2 and up-regulating p53 expression in A2780CP cells.

The association between atrial natriuretic peptide (ANP) polymorphism and coronary heart disease (CHD) was studied in Chinese population. The genotypes of ANP T2238C and ANP C-664G were detected by polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP) methods in 158 consecutive CHD patients and 165 controls. It was found that the distribution of A2A2 genotype in CHD group was significantly higher than that in control group (P<0.05). Stepwise Logistic regression analysis revealed that male, smoking, history of hypertension, history of diabetes, family history of hypertension, high level of serum cholesterol, and ANP T2238C polymorphism were the possible risk factors in patients with CHD (P<0.05). However, there was no significant difference between the patients with CHD and the control group in the distribution of ANP C-664G polymorphism (P>0.05). The results suggest that A2A2 T2238C genotype could be one of the risk factors for CHD (P<0.05, OR: 1.80, 95 % CI: 1.03-3.15).

Objective To assess the diagnostic value of MR imaging of the wrist synovitis in early rheumatoid arthritis.Methods 60 wrists in 30 patients underwent MR imaging examination,including T1WI,T2WI,STIR and contrast-enhanced fat-suppressed 3D fast-gradient-echo sequence.MRI manifestations were analysed in comparison with clinical and laboratory test data.Results All changes including synovial hyperplasia and pannus formation(30 cases),articular cartilage destruction(21 cases),bone erosion(16 cases),joint effusion(25 cases) and tendon lesion of wrists could be showed clearly by MRI.The signal intensity of the pannus before and after administration of contrast agent and the enhanced curve of the pannus could be used to assess the lesions whether or not activation.Conclusion MRI is helpful in diagnosing early rheumatoid arthritis.

CONCLUSION: Processing with live-scorpion has obviously advantage over one with commercial scorpion on element contents.

Objective To investigate the differences in clinical, laboratory and therapeutic aspects of primary Sjogren's syndrome (pSS) between young/middle-age group and old group.Methods The 84 pSS patients were divided into the young and middle-age group (n=54) and the old group (n = 30). The differences in clinical features, laboratory indices and drug therapy were retrospectively analyzed. The chi-square test was used for statistical analysis. Results The positive incidences of xerostomia, dry eye symptom and rampant teeth were 80.0%, 76.7% and 43.3%respectively in the old group. And they were all significantly higher than in young and middle-aged group (57.4%, 51.9% and 20.4%, all P＜0. 05). The positive rates of rheumatoid factor (RF)elevation, antiRo/SSA and antiLa/SSB antibodies were 13. 0%, 36.7% and 16.7% in the old group,and significantly lower than in young and middle-age group (44.4%, 59.3% and 42.6%, all P＜0.05). The incidences of leukopenia and thyroid gland involvement were much lower in the aged group (13.3% and 10.0%) than in the young and middle-age group (48. 1% and 37.0%, P＜0. 05). The percentage of patients receiving hydroxychloroquine as the main medicine was much lower in the aged group than in the young and middle-age group (16.7% vs. 40. 7%, P＜0. 05), while percentage of treatment with exclusive glucosides of Paeony Capsules was much higher (33.3% vs. 14.8%, P＜0.05). There were no statistical differences between two groups in ophthalmological examination,immunoglobulin level and sialography. Conclusions Those pSS patients with late onset exhibit more abnormalities in clinical parameters, but fewer in immunological parameters, which may be helpful in estimating prognosis and pathogenetic factors in pSS.

Objective To investigate the rs501120 and rs17465637 gene polymorphisms,and their relationship with the risk of coronary heart disease(CHD)in Chinese Han population.Methods 775 CHD without treatment and 775 age and gender matched controls were selected for this study,the genotypes of two single nucleotide polymorphisms(SNP)rs501120 and rs17465637 were tested with TaqMan-MGB probes.Results There was no significant difference in the frequency of genotypes of the 2 SNPs between CHD group and control group(P ＞0.05).Stratified analysis showed that SNP rs501120 had significant protection with CHD in people younger than 60 years old(OR 0.4,95% CI 0.2-0.9,P ＜ 0.05)or people with diabetes(OR0.3,95%CI0.1-0.7,P ＜0.05).Conclusions The results suggested that rs501120 was tightly associated with CHD in people younger than 60 years or had diabetes.

Purpose To evaluate the value of real-time contrast-enhanced ultrasound (CEUS) combined with comparative observation in determining the initial time of peripheral lung lesion,and to provide a new method for the diagnosis of peripheral lung disease by CEUS.Materials and Methods Sixty patients with peripheral lung disease diagnosed by chest X-ray or CT examination were examined by CEUS,and the lesions and perfusion of surrounding lung tissue were observed in real time and comparatively.The time of initial enhancement of peripheral lung lesion was determined by real-time comparative observation method,that is,to compare the time of contrast agent to reach the peripheral lung lesion with the time to reach the adjacent gas-containing lung tissue.All lesion specimens were obtained by surgery or ultrasound-guided percutaneous biopsy,and the pathological diagnosis was performed.According to the pathological results,the peripheral lung lesions were classified into the malignant group,the chronic inflammation group and the pneumonia group.Results Sixty cases of peripheral lung lesions were identified as 38 cases of malignant tumors (including 15 cases ofsquamous cell carcinomas,9 cases of adenocarcinoma cell carcinomas,2 cases of large cell carcinomas,9 cases of small cell carcinomas and 3 cases of metastatic carcinomas),14 cases of chronic inflammation lesions (including 7 cases of tuberculomas,3 cases of inflammatory pseudotumors and 4 cases of lung abscess) and 8 cases of pneumonia.The detection rates of pulmonary arterial phase and bronchial artery phase using the real-time comparative observation method were 100％ (60/60) and 85％ (51/60),respectively.The initial time of pulmonary arterial phase and bronchial artery phase were (6.1 ± 0.9) s and (10.5 ± 1.6) s,respectively.The initial time of pulmonary arterial phase was sooner than bronchial artery phase,the difference was statistical significance (P＜0.05).Conclusion The real-time CEUS combined with comparative observation method has important diagnostic value in judging the initial enhancement time of peripheral lung lesion and can provide a new method for the accurate diagnosis of peripheral lung disease,which is worth popularizing.

Objective:To explore the mechanism of social support and self-efficacy in rehabilitation exercise in the relationship between psychological resilience and kinesiophobia in hip fracture patients.Methods:Totally 284 hip fracture patients treated at the Department of Trauma and Orthopedics, Binzhou Medical University Hospital from May 2022 to April 2023 were selected by convenience sampling. Data were collected using the general information questionnaire, the Connor-Davidson Resilience Scale (CD-RISC), the Social Support Rating Scale (SSRS), the Self-Efficacy Rehabilitation Outcome Scale (SER), and the Tampa Scale for Kinesiophobia (TSK). Process 4.1 was used for chain mediation effect analysis.Results:The scores for the 284 hip fracture patients were as follows: CD-RISC (58.72±7.77), SSRS (29.70±5.11), SER (91.23±8.41), and TSK (38.07±3.65). Psychological resilience, social support, self-efficacy in rehabilitation exercise, and kinesiophobia were all significantly correlated pairwise (all P<0.01). Social support and self-efficacy in rehabilitation exercise had a chain mediation effect between psychological resilience and kinesiophobia, with mediation effect values of -0.020 and -0.079, accounting for 17.52% and 67.70% of the total effect, respectively. Conclusions:Psychological resilience directly influences the level of kinesiophobia in hip fracture patients and has an indirect effect through the chain mediation of social support and self-efficacy in rehabilitation exercise.
