To study the adverse reactions' factors to Danhong injection in the real world. A multi-center, large sample and prospective hospital centralized monitoring method was adopted, and 30 888 cases of Danhong injection from 37 national 3A hospitals were collected to carry out a nested case control design study. These cases were divided into adverse reaction group and non-adverse group. Single factor logistic regression and multiple factor logistic regression were used to analyze data, and investigate the correlation between adverse reaction and gender, allergy history, methods of administration, and combined drug use. One hundred and eight cases of adverse reactions in 30 888 patients were determined, with an incidence of 0.35%. The results showed that Danhong injection combined with other medication(potassium mendoxine magnesium, thymic peptide, celecoxib, fumarate bisoprolol) with history of adverse reactions including scephalosporin allergy and proprietary Chinese medicine allergies had more adverse reactions than the control group(<0.05, estimated coefficient>0), indicating that these six factors were the risk factors for the adverse reaction of Danhong injection. The adverse reaction of Danhong injection combined with the aspirin was less than that in the control group(<0.05, estimated coefficient<0), indicating that the aspirin was a non-risk factor for the adverse reaction of Danhong injection. All the above results indicate that the adverse factors to Danhong injection include scephalosporin allergy, patent Chinese medicine allergy, Danhong injection combined with medication(potassium mendoxine magnesium, thymic peptide, celecoxib, fumarate bisoprolol), suggesting special attention shall be paid in clinical application.

OBJECTIVEThe influence of anti-tuberculosis (TB) treatment history on tuberculous lymphadenitis (TBLN) diagnosis is unclear. Therefore, this study aims to evaluate the diagnostic methods, including histology, microbiology, and molecular tests, used for TBLN.

METHODSIn this study, suspected patients with TBLN and having different anti-TB treatment background were enrolled. All the samples were tested simultaneously by histology, Ziehl-Neelsen (ZN) staining, mycobacterial culture (culture), Xpert MTB/RIF (xpert), real-time PCR, and high-resolution melting curve PCR (HRM). Thereafter, the performance of these methods on samples with different anti-TB treatment background was assessed.

RESULTSIn our study, 89 patients were prospectively included 82 patients with TBLN and 7 with other diseases. The overall sensitivities of Xpert, real-time PCR, histology, ZN staining, and culture were 86.6%, 69.5%, 58.5%, 43.9%, and 22.0%, respectively. The anti-TB treatment history revealed dramatic influences on the sensitivity of culture (P < 0.0001). In fact, the treatment that lasted over 3 months also influenced the sensitivity of Xpert (P < 0.05). However, the treatment history did not affect the performance of remaining tests (P > 0.05). For rifampicin drug susceptibility test (DST), the anti-TB treatment showed only significant influence on the success rate of culture DST (P = 0.001), but not on those of Xpert and HRM tests (P > 0.05).

CONCLUSIONOther tests as well as culture should be considered for patients with TBLN having retreatment history or over 1-month treatment to avoid false negative results.

BACKGROUNDThe effects of near-road pollution on lung function in China have not been well studied. We aimed to investigate the effects of long-term exposure to traffic-related air pollution on lung function, airway inflammation, and respiratory symptoms.

METHODSWe enrolled 1003 residents aged 57.96 ± 8.99 years living in the Shichahai Community in Beijing. Distances between home addresses and the nearest major roads were measured to calculate home-road distance. We used the distance categories 1, 2, and 3, representing <100 m, 100-200 m, and >200 m, respectively, as the dose indicator for traffic-related air pollution exposure. Lung function, exhaled breath condensate (EBC) pH, and interleukin 6 levels were measured. As a follow-up, 398 participants had a second lung function assessment about 3 years later, and lung function decline was also examined as an outcome. We used regression analysis to assess the impacts of home-road distance on lung function and respiratory symptoms. As the EBC biomarker data were not normally distributed, we performed correlation analysis between home-road distance categories and EBC biomarkers.

RESULTSParticipants living a shorter distance from major roads had lower percentage of predicted value of forced expiratory volume in 1 s (FEV1% -1.54, 95% confidence interval [CI]: -0.20 to -2.89). The odds ratio for chronic cough was 2.54 (95% CI: 1.57-4.10) for category 1 and 1.97 (95% CI: 1.16-3.37) for category 2, compared with category 3. EBC pH was positively correlated with road distance (rank correlation coefficient of Spearman [rs] = 0.176, P < 0.001).

CONCLUSIONSLong-term exposure to traffic-related air pollution in people who live near major roads in Beijing is associated with lower lung function, airway acidification, and a higher prevalence of chronic cough. EBC pH is a potential useful biomarker for evaluating air pollution exposure.

OBJECTIVETo investigate the efficacy and adverse effects of dapoxetine in the treatment of premature ejaculation.

METHODSWe randomly assigned outpatients with premature ejaculation in the proportion of 2:1 to receive 30 mg dapoxetine on demand (n =78) or 50 mg sertraline qd for one month (n = 39). Follow-up was accomplished in 95 cases, 63 in the dapoxetine group and 32 in the sertraline group. We recorded the intravaginal ejaculatory latency time (IELT), clinical global impression of change (CGIC) score, and adverse reactions of the patients and compared them between the two groups.

RESULTSIELT was significantly increased in both the dapoxetine (from [0.87 ± 0.31] to [2.84 ± 0.68] min, P < 0.05) and the sertraline group (from [0.84 ± 0.28] to [2.71 ± 0.92] min, P < 0.05) after medication. Based on the CGIC scores in premature ejaculation, the rate of excellence or effectiveness was 36.5% in the dapoxetine and 37. 5% in the sertraline group, and the rate of improvement was 63.5% in the former and 71.9% in the latter. The incidence rates of dizziness, nausea, headache, and diarrhea were slightly higher (P > 0.05) while those of fatigue, somnolence, and dry mouth significantly higher (P < 0.05) in the sertraline than in the dapoxetine group.

CONCLUSIONOn-demand oral medication of dapoxetine is effective and well-tolerated for the treatment of premature ejaculation.

The aim of this study was to investigate the relatively frequencies of alleles in the HLA-C*04:01:01G group and to analyze their relations with HLA-A and -B loci. DNA samples previously typed as HLA-C*04:01:01G were sequentially selected. The sequences for exon 2 to 7 of the HLA-C locus were analyzed by polymerase chain reaction sequence-based typing(PCR-SBT). The HLA-A, -B, -DRB1 and -DQB1 loci were genotyped using PCR-SBT method. The results showed that 178 samples (94.2%) and 11 samples (5.8%) were assigned as HLA-C*04:01:01 and HLA-C*04:82 respectively among 189 samples previously typed as HLA-C*04:01:01G. 72 haplotypes associated with HLA-C*04:01:01 and C*04:82 were found, in which the frequencies of 26 haplotypes were over 0.0050. HLA-C*04:01:01 was strongly related with A*02:03, A*02:07, A*11:01, A*33:03, B*13:01, B*15:01, B*15:05, B*15:27, B*40:01, B*54:01 alleles, while HLA-C*04:82 was related with B*40:01. It is concluded that HLA-C*04:01:01 and HLA-C*04:82 alleles were confirmed in the HLA-C*04:01:01G group, which should be discriminated by the routine HLA genotyping.

Neospora caninum is the etiologic agent of bovine neosporosis, which affects the reproductive performance of cattle worldwide. The transmembrane protein, NcSRS2, and dense-granule protein, NcGRA7, were identified as protective antigens based on their ability to induce significant protective immune responses in murine neosporosis models. In the current study, NcSRS2 and NcGRA7 genes were spliced by overlap-extension PCR in a recombinant adenovirus termed Ad5-NcSRS2-NcGRA 7, expressing the NcSRS2-NcGRA7 gene, and the efficacy was evaluated in mice. The results showed that the titer of the recombinant adenovirus was 10(9)TCID50/ml. Three weeks post-boost immunization (w.p.b.i.), the IgG antibody titer in sera was as high as 1:4,096. IFN-gamma and IL-4 levels were significantly different from the control group (P<0.01). This research established a solid foundation for the development of a recombinant adenovirus vaccine against bovine N. caninum.

BACKGROUNDCardiac resynchronization therapy (CRT) with biventricular pacing improves cardiac function, functional capacity and quality of life in selected patients with heart failure. The current study aimed to evaluate the efficacy of the intracardiac electrogram (IEGM)-based optimization method, QuickOpt(TM), in Chinese patients treated with CRT.

METHODSAortic time velocity integrals (AVTI) achieved at the sensed atrioventricular (AV), paced AV and interventricular (VV) interval settings recommended by both QuickOpt(TM) and standard echocardiographic optimization were measured in 101 patients. Consistency and the strength of the relationship between the two timing cycle optimization methods were assessed by intra-class correlation coefficient (ICC).

RESULTSThe ICC showed good agreement and correlation with what the AVTI achieved at the optimal sensed AV (ICC = 0.9683 (0.9535 - 0.9785)), paced AV (ICC = 0.9642 (0.9475 - 0.9757)) and VV (ICC = 0.9730 (0.9602 - 0.9817)) interval settings determined by the two optimization methods. The average time required by echocardiographic optimization and by QuickOpt(TM) were (78.32 ± 32.40) minutes and (1.98 ± 1.64) minutes respectively (P < 0.0001).

CONCLUSIONThe QuickOpt(TM) algorithm provides a quicker, simpler and reliable alternative to the standard method for timing cycle optimization.

This study was aimed to discriminate the alleles in the HLA-C*07:01:01G and HLA-C*07:02:01G groups and analyze their associations with HLA-B locus. Samples previously typed as HLA-C*07:01:01G and HLA-C*07:02:01G were collected. The nucleotide sequences in exons 1 to 7 of the HLA-C locus were sequenced by polymerase chain reaction sequence-based typing (PCR-SBT) and HLA-B genotyping was also preformed by PCR-SBT in these samples. The results showed that 4 samples (30.8%) were confirmed as HLA-C*07:01:01 and 9 samples (69.2%) were HLA-C*07:06 among 13 samples previously typed as HLA-C*07:01:01G. Linkage disequilibrium (LD) analysis showed that HLA-C*07:06 allele was strongly related with HLA-B*44:03. All samples were typed as C*07:02:01 among 102 individuals previously typed as C*07:02:01G. LD analysis showed that C*07:02:01 was strongly related with HLA-B*51:01, B*46:01, B*39:01, B*40:01, B*38:02, B*15:02 alleles. It is concluded that HLA-C*07:01:01 and HLA-C*07:06 alleles are confirmed in the HLA-C*07:01:01G group and HLA-C*07:02:01 is a preferred allele in the HLA-C*07:02:01G.

OBJECTIVETo discriminate and analyze the relative frequencies of alleles in HLA-DRB1*12:01:01G(HLA-DRB1*12:01:01/12:06/12:10/12:17) and HLA-DRB1*14:01:01G (DRB1*14:01:01/14:54) groups and assess their associations with HLA-DRB3 and HLA-DQB1 loci.

METHODSA total of 115 DNA samples previously typed as HLA-DRB1*12:01:01G and 108 samples from HLA-DRB1*14:01:01G were selected. DNA sequences for exons 1 to 3 of the HLA-DRB1 locus were analyzed for HLA-DRB1*12:01:01G, and exons 2 to 3 were analyzed for HLA-DRB1*14:01:01G by polymerase chain reaction sequence-based typing (PCR-SBT). Genotyping of HLA-DRB3 and HLA-DQB1 were achieved by PCR-SBT.

RESULTSAmong 115 samples previously typed as HLA-DRB1*12:01:01G, 101 (87.8%) were confirmed as HLA-DRB1*12:01:01 and 14 (12.2%) were HLA-DRB1*12:10, but HLA-DRB1*12:06 and HLA-DRB1*12:17 alleles were not identified. For 108 samples previously typed as HLA-DRB1*14:01:01G, all were typed as HLA-DRB1*14:54. HLA-DRB1*12:01:01 was linked with HLA-DRB3*01:01:02 and HLA-DQB1*03:01, while HLA-DRB1*12:10 was strongly linked with HLA-DRB3*02:02:01 and HLA-DQB1*03:01. HLA-DRB1*14:54 was strongly linked with HLA-DRB3*02:02:01 and two different HLA-DQB1*05:02, *05:03 alleles.

CONCLUSIONHLA-DRB1*12:01:01 was more prevalent than HLA-DRB1*12:10 in the HLA-DRB1*12:01:01G group, and HLA-DRB1*14:54 was the dominant allele for HLA-DRB1*14:01:01G.

OBJECTIVETo investigate the recombination events between human leukocyte antigen (HLA) loci within two families.

METHODSIdentification of HLA-A, -C, -B, -DRB1 and -DQB1 loci was firstly carried out using polymerase chain reaction-sequence specific oligonucleotide. Then HLA high resolution typing was performed using polymerase chain reaction sequencing-based typing. The recombination between HLA loci was identified by family genetic analysis. The parentage possibility was analyzed by short tandom repeat technique.

RESULTSRecombination between the HLA-A and C loci was identified within two families. One individual inherited a paternal haplotype that was the result of a recombination event between the father's HLA-A and -C loci on his chromosomes. The other individual inherited a maternal haplotype that was the result of a recombination event between the mother's HLA-A and -C loci. The high parentage possibilities were obtained in the family members.

CONCLUSIONThe recombination events of HLA-A and -C have been found in two Chinese families, which may help further study on the mechanism of HLA recombination.
