Objective To investigate the mRNA espression level of Caspase-1 and Caspase-3 in the patients with systemic lupus erythematosus(SLE) and its association with lymphocyte apoptosis. Methods Reverse transcription-polymerase reaction (RT-PCR) technique was applied to semiquantitatively analyze the mRNA expression of Caspase-1 and Caspase-3 in the peripheral blood mononuclear cells (PBMC) from 34 active SLE patients and 30 healthy subjects. Results Compared with normal controls, the mean levels of Caspase-1 or Caspase-3 mRNA expression in active SLE group was significantly increased(P0.05). Conclusion There are increased expressin of Caspase-1 and Caspase-3 in the PBMC of SLE patients, which may be involved in the lymphocyte apoptosis of SLE patients.

Objective To assess the association between polymorphism within the interleukin-10 receptor cDNA gene (IL-10R) and Chinese patients with systemic lupus erythematosus (SLE). Methods The IL-10R genotypes of 94 SLE patients and 80 healthy subjects were examined by reverse transcription-polymerase chain reaction-single strand conformation polymorphism method (RT-PCR-SSCP), RT-PCR-restriction fragment length polymorphism (RFLP) and DNA sequencing. Results There were significant differences in the IL-10R2 genotype frequencies of these two groups. The IL-10R2 G520/G520 genotype increased the risk of developing SLE (OR = 0.515, 95% CI 0.414-0.579, P = 0.004) and individuals who had G520/A520 genotype also had a higher susceptibility to SLE (OR = 1.968, 95% CI 0.981-3.949, P = 0.055). There was no significant association between SLE and IL-10R1 genotypes. The risk of developing SLE was detected in the individuals who had the combination of IL-10R1 G241/G241 and IL-10R2 G520/G520 (OR = 0.515, 95% CI 0.444-0.597, P = 0.004). Conclusion The IL-10R2 genotypes of G520/G520 and G520/A520 as well as the combination of genotypes IL-10R1G241/G241 and IL-10R2 G520/G520 may increase the susceptibility to SLE in Chinese people.

Objective To compare the validity of four commercially available ELISA kits for detecting HSV-2 type-specific IgG antibodies. Methods A total of 125 serum specimens were collected from 105 patients with genital ulcers and 20 normal individuals without history of STDs. Four ELISA kits which are commercially available in China for the detection of HSV-2 type-specific IgG antibodies were selected for the evaluation. Western blot assay was used as the gold standard. Results Based on the results of detection by Western blot assay, the sensitivity and specificity of these ELISA kits including home-made 1, home-made 2, improted 1 and improted 2 were 13.1% and 98.4%, 7.5% and 100%, 100% and 11.1%, 87.7% and 96.7%, respectively. The areas under the ROC curve of three kits including home-made 1, imported 1 and imported 2 were 0.885 (0.822 - 0.948), 0.852 (0.747 - 0.902), 0.947 (0.950 - 0.998), respectively. Conclusions The results of imported 2 are well consistent with those of Western blot, while the results of other 3 kits are poorly consistent with those of Western blot. It is also indicated that the commercially available ELISA kits for detecting HSV-2 type-specific antibodies should be re-evaluated in terms of their validity befor being applied for the clinical diagnosis as well as laboratory research.

Objective To observe the clinical efficacy and safety of 0.1% mometasone furoate cream in the topical treatment of eczematous dermatoses including neurodermatitis and eczema. Methods A randomized double-blind parallel controlled clinical trial was conducted. The home made mometasone furoate cream or imported Eloson cream was topically used in patients with such dermatoses once daily for 4 weeks, respectively. Symptom/sign scores were evaluated at the beginning of the treatment and at the 1st, 2nd, 3rd, 4th week after the initiation of the treatment. Results Two hundred and eighty-four patients were enrolled in the trial, including 143 patients with eczema and 141 patients with neurodermatitis. There are 142 patients each in test group and control group separately. All symptom/sign scores and total scores were significantly decreased 1, 2, 3, and 4 week after the treatment. No statistically significant difference was observed between the two groups. The cure rate and improvement rate in eczema patients were 78.87% and 97.18% in the test group; 84.51% and 92.96% in the control group; respectively. While the cure rate and improvement rate in neurodermatitis patients were 75.71% and 100% in the test group; 80.28% and 94.37% in the control group; respectively. The cure rate and improvement rate of total patients were 77.30% and 98.58% in the test group; 82.39% and 93.64% in the control group; respectively. No statistically significant difference in efficacy was observed between the two groups. There was no severe side effect in the two groups. One patient had mild contact dermatitis in the test group. Conclusions These results suggest that 0.1% mometasone furoate cream is an effective and safe drug in the treatment of neurodermatitis and eczema.

Objective To investigate the role of IL-6 and IL-6R in the pathogenesis of systemic lupus erythematosus (SLE) and its clinical significance. Methods RT-PCR technique was used to semiquantitatively analyze IL-6R mRNA expression in peripheral blood mononuclear cells (PBMC), and double antibody sandwich ELISA was applied to determine the serum level of IL-6 from 89 SLE patients . Results The positive IL-6R mRNA expression was found in each individuals among active SLE group (groupⅠ), inactive SLE group (groupⅡ) and control group (group Ⅲ). The mean levels of IL-6R mRNA expressions in groupⅠ,Ⅱ or Ⅲ were 0.902 ? 0.273, 0.519?0.11 and 0.573?0.24, respectively. Compared with group Ⅱand group Ⅲ, the mean level of IL-6R mRNA expression in groupⅠ was markedly increased (P = 0.00), while there was no statistical difference between group Ⅱ and group Ⅲ(P = 0.289). The mean serum levels of IL-6 in groupⅠ,Ⅱ and Ⅲ were 71.89 ? 20.02,17.96 ? 6.93, and 0.035 ? 0.035, respectively. Compared with group Ⅱand group Ⅲ, the mean level of IL-6 in groupⅠ was significantly higher than those in groupⅡ and groupⅢ (P = 0.00), while that in groupⅡwas higher than group Ⅲ (P = 0.00). There was a positive correlation between IL-6 and IL-6R in active SLE group and inactive SLE group(r = 0.887, and r = 0.615 P

【Objective】 To perform quantitative analysis on the sample provincial laws and regulations for voluntary blood donation, and provide reference for further revision of laws and regulations. 【Methods】 31 study samples were current provincial laws and regulations for voluntary blood donation that can be collected from open sources. The issue date and the revision date of each sample were recorded. With "The Blood Donation Law of the People’s Republic of China" as reference, 5 categories were formed and additional clauses in samples were coded and rated following content analysis procedures. Sample provinces were divided into two groups based on donation rate and their differences in evaluation scores of categories were examined using rank sum test. 【Results】 Until December, 2021, 31 sample provinces had issued and implemented provincial laws and regulation for voluntary blood donation, and 14 of which had been revised. Many detailed clauses (total score 9.32±3.09) were added in sample provincial laws and regulations, more clauses were added in the categories of 'related government agencies and their responsibilities’, 'management of clinical blood use’ and 'rewards and punishment’. Sample provinces were divided into two groups according to the donation rate per 1 000 people recommended by World Health Organization(10‰). Compared to lower donation rate group, the total score and sub score in the categories of 'basic principles’, 'management of blood collection and supply’ were significantly higher in higher donation rate group. 【Conclusion】 In revision and improvement of provincial laws and regulations, 'basic principles’ and 'management of blood collection and supply’ could be considered. This assay mainly tries to provide a new research perspective and perform quantitative analysis on content of sample provincial laws and regulation for voluntary blood donation, the actual effect of the results in this study need longer time to be examined, and we will keep following its new advances.
