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.

We isolated and identified the bacterial pathogen in a pyogenic balanoposthitis patient and investigated the drug resistance and its mechanism of the isolate.Urethral secretions and balanus pustule liquids were collected for microscopic examination after Gram-staining and detection of mycoplasma using Mycoplasma IST 2 kit.The two samples were inoculated on Columbia blood plate,N.gonorrhoeae selective plate and chromID Candida plate for isolation.The obtained colonies were identified by VITEK 2-compact automatic bacterial detection and analysis system.Moreover,PCR was performed to detect 16S rRNA gene of N.gonorrhoeae in the samples and colonies.KB method was applied for detecting susceptibility of five common antibiotics against the isolate.The β-lactamase and extended spectrum β-lactamase confirmatory tests were used to investigate the enzyme production of the isolate as well as drug resistance-associated tetM,TEM,mefA and ermF genes in the isolate were detected by PCR.Results showed that all the clinic samples showed negative for mycoplasma.All the isolating cultivation results of urethral secretions were negative while the balanus pustule liquids provided positive isolating cultivation in the blood and selective plates.The VITEK 2-compact system and 16S rRNA-PCR revealed that the isolated strain belongs to N.gonorrhoeae.The isolate can produce β-lactamases and resist to penicillin G,ciprofloxacin and tetracycline.The tetM,TEM,mefA and ermF genes could be found in the isolate's genome.The patient's balanoposthitis is caused by infection of N.gonorrhoeae.The multidrug resistance of Neisseria gonorrhoeae isolate is closely associated with its carried resistant genes.

Objective To investigate the effects of rehabilitation intervening in different stage on activities of daily living of old stroke patients. Methods 74 old cases were divided into 3 group according to the time from onset of stroke to rehabilitation intervention: group A (＜3 months), group B (3～6 months), and group C (>6 months). They were treated with routine rehabilitation for 2 months and assessed with Barthel Index before and after rehabilitation. Results All the patients improved their ADL significantly after rehabilitation (P=0.000), and those in group A improved more than in group C (P<0.05). There was no significant difference between group A and B, and group B and C (P>0.05). Conclusion The rehabilitation can effectively improve the ADL of old stroke patients. The early the rehabilitation intervenes, the better the ADL is.

Objective To investigate whether ligustrazine can reduce endotoxemia and inhibit the increase of lipopolysaccharide (LPS)-induced vascular permeability by suppressing Rho/ROCK signaling pathway in guinea pigs. Methods Eighteen of white male healthy guinea pigs were divided into three groups randomly and pretreated with intravenous injection of ligustrazine(3 or 6 mg/kg) or saline. 30 min later, LPS (100, 300, 1 000 μg/0.1 mL/site) and saline (0.1 mL/site) were administered intracutaneously at the dorsum of guinea pigs. Vascular permeability was determined by leakage area and absorbance of 610 nm (OD610) of Evans Blue dye after intracutaneous injection of LPS (100-1 000 μg/site). Results Dye leakage in the skin began to increase at 5 min, and revealed significant increase 2 h after LPS injection. Significant differences in the dye leakage area(F = 5.77, P < 0.05) and the OD610 (F = 7.736, P < 0.05) induced by 100, 300 and 1,000 ug/site of LPS administration were demonstrated between the control and ligustrazine groups (3 or 6 mg/kg). Conclusion Ligustrazine has protective effect on the hypermeability of endothelial cells induced by lipopolysaccharide, and inhibition of Rho/ROCK signaling pathway is a possible mechanism.

Objective To investigate subacute exposure of airborne particulate matter (PM) on pregnancy and fetal development in female mice. Methods Forty female and forty male ICR adult mice group (A), small (B) , middle (C) , large (D) or overdose (E) PM challenge groups (n = 8 - 11), and were administered with 30 μl of phosphate buffered solution (A) or resuspended standard PM SRM 1649a at 0.09 (B), 0.52 (C), 1.85 (D) or 69.2 (E) μg/μl, once per trid from d 0 till d 19 of pregnancy via instillation onto the base of the tongue. Fetal mice were harvested by cesarean section at the time when spontaneous delivery occurred. Body weight of the pregnant mice, gestational days, intrauterine survival and growth, hepatic and pneumonic histopathological changes of the fetal mice were investigated. Lung/body and liver/body weight ratios were calculated. Expressions of mRNA and protein of CYP1A1 in the fetal lung and CYP1 A2 in the fetal liver were assayed. Results (1) All of the pregnant mice survived pregnancy throughout the entire experiment. Body weight of the pregnant mice was not significantly different among all the groups at gestational d 1 and 7 (P ＞ 0.05), but significantly lower in group E [(41.8 ± 5.8) and (48.9 ± 8.9) g] than in group A [(45.9 ± 1.8) and (56.2 ± 4.9) g] at gestational d 14 and 18 (P ＜0.05). The gestational days were significantly decreased in group E [(19.3 ± 1.3) d] when compared with group A [(20.5 ± 0.7) d; P ＜ 0.05] and were not significantly different among groups A, B, C and D (P ＞ 0.05). Lung/body and liver/body weight ratios of the fetal mice were significantly increased in group E [(1.21 ±0.18) and (4.68 ±0.21)%] as compared with groups A, B, C and D (P＜0.05). (2)Mortality rates of the fetuses were significantly higher in group E (23.0%) than in groups A (0.8%), B (0.9%), C (1.7%) and D (3.7%) (P ＜ 0.05), but were not significantly different among groups A,B, C and D (P ＞ 0.05) despite of an increasing tendency. (3) Pathological changes in the liver and lung of the fetuses were conspicuous in group E. The fetal liver injury was histopathologically evidenced by deranged tissue structure, degenerated parenchyma of hepatic cells, and mildly stained cytoplasm. Adipose degeneration was represented by clear-boundary intracytoplasmic vacuoles in most of the liver cells, and cell pyknosis with heavily stained cytoplasm was observed in some of the liver cells. Inflammatory cell infiltration and focal necrosis were occasionally found in the hepatic tissue. The fetal lung exhibited bronchiole with narrow lumina, vascular engorgement in the submucosal layer, interstitial and alveolar edema, thickened alveolar septum, granulocyte and lymphocyte infiltrations within the pulmonary alveoli and around the bronchioles. The above pathological changes were lesser in groups C and D, and were not or least found in groups A and B. (4) Protein expressions of CYP1A1 in the fetal lung and CYP1A2 in the fetal liver were significantly increased in group E (1.20 ± 0.40 and 2.55 ± 0.89) when compared with group A (0.77 ±0.36 and 2.08 ±0.31) (P ＜ 0.05). mRNA expressions of CYP1A1 in the fetal lung were significantly increased in groups C (0.36 ±0.12), D (0.41 ±0.08) and E (0.43 ±0.11) compared with group A (0.21 ±0.10), and significantly increased in groups D and E compared with group B (0.28 ±0.10,P＜0.05). mRNA expressions of CYP1 A2 in the fetal liver were significantly increased in groups C (0.37 ±0.13), D (0.36 ±0.14) and E (0.43 ±0.16) compared with group A (0.21 ±0.03), and significantly increased in group E compared with group B (0.24± 0.11, P ＜ 0.05). Conclusions PM elicited embryotoxigenicity and resulted in adverse pregnancy outcomes in mice by intrauterine exposure of overdose PM. The expressions of cancer-related genes CYP1A1 and CYP1A2 were up-regulated in organs after the middle- and large-dose subacute exposure of PM, which may have a potential role on the future development.
