BACKGROUND:Long-term use of corticosteroids (hereinafter referred to as hormone) after renal transplantation could obviously lead to adverse reactions. Immunosuppressive regimen with less and no hormone has been a hot focus in the study of renal transplantation al over the world. However, reduction or withdrawal of hormones has a certain risk. At present, there is no unified scheme. Because urine protein can be immediately detected after tubular injury, to monitor urine protein can find the renal dysfunction after transplantation in recipients undergoing renal transplantation, which can gain time for clinical therapy. OBJECTIVE:To discuss the influence of hormone (prednisone) removal on the occurrence of urine protein in recipients undergoing renal transplantation. METHODS:A total of 35 recipients undergoing renal transplantation after removal of prednisone received immunosuppressive regimen of cyclosporine A or tacrolimus+mycophenolate mofetil bivalent. Initial dose of prednisone was 30 mg/d, and then gradual y reduced by 5 mg per week, and withdrawn at 1 month after renal transplantation. There were 16 cases in cyclosporine A group and 19 cases in tacrolimus group. Urine protein was measured and quantified at 3, 6, 12 and 24 months after renal transplantation and 3, 6 and 12 months after addition of prednisone in both groups. Simultaneously, serum creatinine, fasting glucose, body mass increases, the rate of acute rejection, infection, patient/graft survival at 2 years after renal transplantation and urine protein at 24 hours before and after adding hormone were recorded. RESULTS AND CONCLUSION:For the two groups, urineα1-microglobulin started to rise after 6 months of removal of prednisone. Urinary microalbumin, urinaryα1-microglobulin, and urinary transferrin ascended obviously at 12 months. Urinary protein was positive in five cases of cyclosporine A group and in three cases of tacrolimus group. At 24 months, urinary microalbumin, urinaryα1-microglobulin, urinary transferrin and urinary IgG ascended obviously. Urinary protein was positive in cyclosporine A group with 11 cases and in tacrolimus group with 10 cases. 24-hour urinary protein quantity was more than 1 g in every case. On this base, we made the patients to take more prednisone for 6 months, so urineα1-microglobulin and urinary microalbumin began to descend. Each group had one case of positive urinary protein turning to negative. Twelve months after the adjustment of the prednisone, urinary microalbumin, urinaryα1-microglobulin, and urinary transferrin descended respectively. Positive urinary protein turned into negative:in cyclosporine A group with two cases and in tacrolimus group with three cases. 24-hour urinary protein quantity was around 0.7 g. Two years after renal transplantation, serum creatinine and acute rejection rates were higher in the cyclosporine A group than in the tacrolimus group (P<0.05). No significant difference in fasting glucose, body mass increase, infections, and patient/graft survival was detectable between both groups. Results suggested that removal of prednisone greatly affected urine protein in recipients undergoing renal transplantation. In particular, at 2 years after renal transplantation, urinary microalbumin, urinaryα1-microglobulin, urinary transferrin and urinary IgG ascended obviously, and the security needs further research.

Objective To explore the influence of individualized health education to asthma children on the quality of life of their parents.Methods One hundred and one parents of asthmatic children from 3 different communities were randomly assigned to the intervention group(n=52)and the control group(n=49).Follow-ups were performed by phone calls and the Children Asthma Health Education Brochures were distributed among them in the two groups,meanwhile the individualized health education was given to the intervention group.The paediatric asthma caregiver's quality of life questionnaire(PACQLQ)was used to assess the quality of life of two groups.Results One month after intervention,the scores of the intervention group on PACQLQ total score as well as its items of activity limitation and emotional function were significantly higher than the control group(P<0.001 for all).Conclusion The individualized health education to the asthmatic children can improve the quality of life of their parents.

Objective:To evaluate the outcome and prognostic factors of conventional radiotherapy followed by intensity-modulated radiation therapy (IMRT) as a boost combined with chemotherapy in the treatment of high-grade gliomas (HGG). Methods:From Nov. 2004 to Nov. 2006, 112 HGG patients were treated with conventional radiotherapy followed by IMRT as a boost combined with chemotherapy. The radiotherapy regimen included first-course conventional radiotherapy and latE-course IMRT as a boost with the total radiation dosage of 57.5- 62.5Gy (27-29 fractions in 37-45 days). All the patients received chemotherapy. Sixty-three patients received temozolomidE-based chemotherapy and 49 patients received semustine plus teniposide chemotherapy. The treatment reaction was recorded. The overall survival rate and local progression-free survival rate were calculated. The prognostic factors were analyzed by using multivariate COX regression model. Results:The acute treatment toxicity was the most at grade 1 to grade 2 and no grade 4 adverse reaction was observed. Three cases had late radiation-induced brain necrosis. The overall 1-, 2-, and 3-year survival rates were 78.9%, 54.7%, and 30.8%, respectively. Multivariate analysis revealed that tumor location (P=0.001) and KPS score (P=0.011) were independent prognostic factors. The 1-, 2-, 3-year local progression-free survival rates were 63.8%, 38.9%, and 10.5%, respectively. Multivariate analysis revealed that tumor location (P=0.001), KPS score (P=0.001), and histologic type (P=0.005) were independent prognostic factors. Multivariate analysis did not reveal the significant correlation of temozolomide chemotherapy with the prognosis of the patients. Conclusion:Postoperative conventional radiotherapy followed by IMRT as a boost combined with chemotherapy has better short-term efficacy in the treatment of HGG and the adverse reaction is tolerable. KPS score, tumor location, and histologic type are important prognostic factors. Temozolomide chemotherapy is not associated with the prognosis of patients.

Objective To investigate the effect of interferon-γ(IFN-γ) on the expression of indoleamine 2,3-dioxygenase(IDO),and tryptophanyl-tRNA-synthetase (TTS) in thyrocytes; and to study the relevant immunopathological significance in Graves' disease.Methods The expressions of IDO and TTS genes in IFN-γ stimulated Nthy-ori3-1 cell line and human thyrocytes,as well as in human thyroid tissues were determined by realtime quantitative PCR.Results IDO and TTS genes were expressed slightly in both Nthy-ori3-1 cell line and human thyrocytes,and were significantly up-regulated after IFN-γ stimulation(P＜0.01).Compared to healthy controls,TTS mRNA level was higher in thyroid tissues of patients with Graves' disease (P =0.018 2),while IDO mRNA level showed no difference,but was notably correlated with IFN-γ mRNA level (R2 =0.716,P =0.002).Conclusion In the early stage of Graves' disease,thyrocytes may decompose local tryptophan by enhancing the expression of IDO and TTS under IFN-γstimulation,thus inhibit auto-reactive function of lymphocytes and balance excessive autoimmune reaction.

OBJECTIVETo investigate the drug resistance of HIV patients to the HIV-1 CRF01_AE and CRF07_BC strains in Sichuan province during 2010 to 2013.

METHODS1.5 ml of plasma were collected from AIDS patients who had been receiving anti-retroviral treatment for over 6 months but still had a HIV-1 virus load of over 1 000 copies/ml from January 1, 2010 to December 31, 2013 in Sichuan province. Genetic analysis of the HIV-1 pol gene was performed using self-established method, and patients with a positive drug-resistant HIV-1 pol gene mutation were included. HIV-1 poly gene was successfully sequenced for a total of 1 213 patients. Drug resistance of different HIV-1 strains was compared with χ2 test or Fisher exact test.

RESULTS558 cases (46.0%) of the 1 213 successfully sequenced patients were infected by HIV-1-strains with drug-resistant mutations, including 327 cases (58.6%) infected by CRF01_AE strain, 126 (22.6%) by CRF07_BC strain, 46 (8.2%) by CRF08_BC strain, 33 (5.9%) by B strain, 4 (0.7%) by C strain, 1 (0.2%) by CRF02_AG strain, and 21 (3.8%) by unidentified strains. Drug-resistant mutation analysis revealed that L33, F116, L74, Q151, and T69 resistance mutations occurred only in the CRF01_AE strain, while A71, K43, and Q58 resistance mutations occurred only in the CRF07_BC strain; in nuclear nucleoside reverse transcriptase inhibitors (NRTIs) and non nucleoside reverse transcriptase inhibitors (NNRTIs), CRF01_AE subtype strains showed highly resistant rate were higher than CRF07_BC, CRF08_BC and B subtype strains, with the differences were statistically significant (P<0.05).

CONCLUSIONThe drug-resistant HIV-1 strains in Sichuan mainly included the CRF01_AE and CRF07_BC strains, which had different resistance mutations.

Antimicrobial peptides (AMPs) are small molecule peptides that are widely found in living organisms with broad-spectrum antibacterial activity and immunomodulatory effect. Due to slower emergence of resistance, excellent clinical potential and wide range of application, AMP is a strong alternative to conventional antibiotics. AMP recognition is a significant direction in the field of AMP research. The high cost, low efficiency and long period shortcomings of the wet experiment methods prevent it from meeting the need for the large-scale AMP recognition. Therefore, computer-aided identification methods are important supplements to AMP recognition approaches, and one of the key issues is how to improve the accuracy. Protein sequences could be approximated as a language composed of amino acids. Consequently, rich features may be extracted using natural language processing (NLP) techniques. In this paper, we combine the pre-trained model BERT and the fine-tuned structure Text-CNN in the field of NLP to model protein languages, develop an open-source available antimicrobial peptide recognition tool and conduct a comparison with other five published tools. The experimental results show that the optimization of the two-phase training approach brings an overall improvement in accuracy, sensitivity, specificity, and Matthew correlation coefficient, offering a novel approach for further research on AMP recognition.

ObjectiveTo evaluate the effectiveness of stone needle thermocompression and massage compared to flurbiprofen gel patch in relieving chronic musculoskeletal pain in the shoulder and back， and to explore the potential mediating mechanism through muscle elasticity. MethodsA total of 120 patients with chronic musculoskeletal pain in the shoulder and back were randomly assigned to either stone needle group or flurbiprofen group， with 60 patients in each. The stone needle group received stone needle thermocompression and massage for 30 minutes， three times per week； the flurbiprofen group received flurbiprofen gel patch twice daily. Both groups were treated for 2 weeks. Pain improvement， as the primary outcome， was assessed using the Global Pain Scale （GPS） at baseline， after 2 weeks of treatment， and again 2 weeks post-treatment. To explore potential mechanisms， a mediator analysis was conducted by measuring changes in superficial and deep muscle elasticity using musculoskeletal ultrasound at baseline and after the 2-week treatment period. ResultsThe stone needle group showed significantly greater pain relief than the flurbiprofen group 2 weeks post-treatment. After adjusting for confounders related to pain duration， the between-group mean difference was -8.8 ［95% CI （-18.2， -0.7）， P＜0.05］. Part of the therapeutic effect was mediated by changes in deep muscle elasticity， with a mediation effect size of -1.5 ［95% CI （-2.0， -0.9）， P = 0.024］， accounting for 17.9% of the total effect. ConclusionStone needle thermocompression and massage can effectively relieve chronic musculoskeletal pain in the shoulder and back， partly through a mediating effect of improved deep muscle elasticity.
