Objective To establish a method of TRFIA with high sensitivity and broad detecting range for serum HBV large surface protein (HBV-LP).Methods The monoclonal antibody of HBV-LP was covered on the microwell plate and incubated with HBV-LP in blood sample,then Eu3+ labeled antibody of HBs was added.HBV-LP in standard substance,blood samples of 66 chronic hepatitis B patients and 30 healthy controls was detected by the TRFIA and ELISA.x2 test and linear correlation analysis were used for data analysis.Results The dose-response curve of standard substance with TRFIA had good linear correlation (r=0.999).Normal reference range was established at 0-1.36 mg/L based on the ELISA results of 30 healthy controls.The sensitivity was 0.10 mg/L.The specificity was 100％ (30/30).Correlation coefficient between the TRFIA and the ELISA was 0.800 9 (P＜0.001).The positive detecting rates of the 2 methods were significantly different (89.4％(59/66) vs 77.3％(51/66),x2 =6.13,P＜0.01).The recovery rate for HBV-LP was between 95.93％-107.62％.The effective detecting range(CV＜10％) of TRFIA was 1.35-2 764.00 mg/L,and that of ELISA was 10.8-691.0 mg/L.Conclusion The TRFIA was established for HBV-LP detection with higher sensitivity and wider detecting range compared to ELISA.It has potential value for HBV screening and monitoring of antiviral therapy.

Objective The change of thyroid hormones affects male sexual function, but the underlying physiological mechanism is not yet clear.The aim of this study was to explore the association of thyroid hormones with abnormal penile neuro-electrophysiology in patients with premature ejaculation (PE).Methods This retrospective study included 52 acquired PE (APE) patients aged 35.36 ± 8.39 years and 24 healthy males aged 32.87±7.45 years.We measured the levels of thyroid hormones in all the subjects and, based on the latency time of penile sympathetic skin responses (PSSR), classified the APE patients into a normal (n=31) and an abnormal PSSR type (n=31).Results The concentration of total tetraiodothyronine (TT4) in the serum was significantly higher in the APE patients than in the normal control ([102.81±18.37] vs [92.68±11.56] nmol/L, P=0.018).The levels of serum TT4 and free tetraiodothyronine (FT4) were both markedly increased in the APE patients of the abnormal PSSR type as compared with those of the normal PSSR type ([113.28±20.89] vs [95.72±12.42] nmol/L, P<0.001 and [12.02±0.88] vs [10.81±1.63] nmol/L, P=0.003).The FT4 concentration was correlated negatively with the latency time of PSSR (r=-0.363, P=0.008) and positively with the Premature Ejaculation Diagnostic Tool (PEDT) scores (r=0.455, P=0.001).Conclusion Abnormal PSSR may be associated with elevated levels of thyroid hormones in APE patients, and regulation of thyroid hormone levels may help improve the symptoms of PE with abnormal PSSR.

BACKGROUND:In recent years, tissue engineering technology as a new model for tissue regeneration has provided new ideas and methods for the repair of periodontal tissue defects. OBJECTIVE:To investigate the effect of human periodontal ligament cels-polyglycolic acid scaffold complex for repair of periodontal tissue defects. METHODS:Passage 4 human periodontal ligament cels at a density of 1.5×109/L were seeded onto the polyglycolic acid scaffold to prepare cel-scaffold complex. Then mongrel dogs were selected to make animal models of periodontal tissue defects and then randomly assigned into experimental group subjected to cel-scaffold complex implantation or control group subjected to direct coronal reset and suture of the gingival flap. Colagen content, new blood capilaries, new cementum, new alveolar bone and new periodontal ligament were detected within 4 weeks after operation; hematoxylin-eosin staining of periodontal tissue defects was done at 8 weeks after operation. RESULTS AND CONCLUSION:In the experimental group, the colagen content, number of newborn capilaries, amount of new cementum, new alveolar bone and new periodontal ligament tissues were significantly higher than those in the control group at postoperative 1, 2, 3, 4 weeks (P< 0.05). At 8 weeks after operation, in the experimental group, there were more vessels arranging on the connective tissue surface of new alveolar bone, the alveolar bone showed a sawtooth-like interlinking with the periodontal tissues in the presence of a thin layer of cementum; in the control group, only new alveolar bone and cementum formed below the incisure. These findings indicate that human periodontal ligament cels-polyglycolic acid scaffold complex can promote periodontal tissue regeneration.

Objective To investigate the predictive value of preprocedural cystatin C level for contrast-in-duced acute kidney injury (CI-AKI) and poor long-term outcome after cardiac catheterization. Methods One thou-sand one hundred and fifty-four patients underwent cardiac catheterization were enrolled in Guangdong general hos-pital. The level of serum cystatin C was determined at 24 hours pre-operation. A 2-year follow up was performed for each patient. Preprocedural cystatin C level was compared between patients with or without CI-AKI. The cystatin C quartiles were compared between patients with incidence of CI-AKI and patients with adverse in-hospital outcomes. Analyses of the receiver operating characteristic curves (ROC) were performed to evaluate the predictive value and cutoff level of cystatin C level for CI-AKI. The log-rank test and Cox regression analyses were also performed to in-vestigate the correlation between cystatin C level and poor long-term outcomes. Results CI-AKI occurred in 42 patients (3.6%). The cystatin C level was significantly higher in the CI-AKI group than that in the non-CI-AKI gu-oup (1.76 ± 1.05 vs 1.20 ± 0.50 mg/L, P=0.001). Patients with higher cystatin C level also had higher risk of CI-AKI and adverse in-hospital outcomes. ROC and Youden index showed that 1.3 mg/L cystatin C of was a fair dis-criminator for CI-AKI, but not significantly different from the Mehran CI-AKI score (AUC, 0.75 vs 0.76, P =0.874). After adjusting for other known CI-AKI risk factors, cystatin C level over 1.3 mg/L remained significantly associated with CI-AKI. During the long-term follow-up , the patients with cystatin C level over 1.3 mg/L were at a higher risk of all-cause mortality and MACEs (P < 0.001). Concusions A preprocedural cystatin C level over 1.3 mg/L was a good predictor of CI-AKI and poor long-term outcomes after cardiac catheterization.

Objective To explore the influence of network intervention on lifestyle and behaviors habit of the middle -aged patients with hypertension.Methods All 300 middle -aged patients with hypertension were randomly assigned into the study group and the control group.Each group had 150 cases.All patients in the both two groups were given hypotensive drugs according to treatment specification of hypertension.The patients in the study group received a network intervention for 2 years,while the patients in the control group received an outpatient service follow-up.The difference of lifestyle and behaviors habit of the patients in the two groups were observed and compared. Results There were no significant differences with all items of the lifestyle and behaviors habit of the patients between the two groups before intervention(P >0.05 ).In the 12th end of month after intervention,there were no significant differences between the two groups with the items of smoking control,working and resting regularly,hobby and psychological balance(P >0.05),but other items in the study group were significantly better than those in the control group(Z =-3.062,-2.509,-2.239,-2.056,-2.126,-2.045,-2.023,all P <0.05).In the 24th end of month after intervention,all items in the study group were significantly better than those in the control group (Z =-4.078,-3.792,-2.080,-2.098,-1.985,-2.478,-2.173,-2.478,-3.290,-2.514,-2.730,all P <0.05 ).Conclusion The network intervention can significantly improve lifestyle and behaviors habit of the middle -aged patients with hypertension.Its effect is much better than that of outpatient service follow -up.

Recent research based on various animal models has shown the neuroprotective effects of erythropoietin (EPO). However, few studies have examined such effects of EPO in the clinic. In this study we enrolled patients with spinal cord ischemia-reperfusion (I-R) injury to investigate the clinical application of EPO and methylprednisolone (MP) for the neuroprotection against spinal cord I-R injury. Retrospective analysis of 63 cases of spinal cord I-R injury was performed. The Frankel neurological performance scale was used to evaluate the neurological function after spinal cord injury (SCI), including 12 cases of scale B, 30 cases of scale C, and 21 cases of scale D. These cases were divided into 2 groups: group A (27 cases) got treatment with both EPO and MP; group B (36 cases) got treatment with MP only. The neurological function of patients after treatment was evaluated by American Spinal Cord Injury Association (ASIA) index score, and activity of daily living (ADL) of the patients was also recorded. All patients got follow-up and the follow-up period ranged from 24 to 39 months (mean 26 months). There was no significance difference in neurological function between groups A and B before the treatment (P>0.05). However, the neurological function and ADL scores were significantly improved 1 week, 1 year or 2 years after the treatment compared to those before the treatment (P<0.05), and the improvement was more significant in group A than in group B (P<0.05). It is suggested that the clinical application of EPO and MP provides the neuroprotection against spinal cord I-R injury.
