Objective To investigate the effect of butylphthalide (NBP) on H2S content and the expression of NR2B in the hippocampus of alcohol dependence rats. Methods A total of 84 SD male rats were randomly divided into 6 groups. Except for the normal group, other groups were subjected to alcohol solution with concentration of 6% ( V/V) for 28 d. Drug intervention began at the 14th day,and rats in the low,medium,high dose group were treated with NBP with a different concentration. Erden abstinence scoring was used to evaluate the rats withdrawal symptom. H2S content was measured in one side of hippocampus and CBS activity was tested in the other side of hippocampus. Hippocampus of 3 rats from each group was used to investigate NR2B mRNA level. Results Withdrawal symptom score ( 12.27 ± 1. 19),H2S content(30. 25 ±8.82), CBS activity (72. 44 ±7. 46) and NR2B mRNA expression( 19. 47 ±0. 86) in medium dose NBP group rats were lower than withdrawal symptom score(14.09 ±2.21) ,H2S content(44. 50 ±6. 65) , CBS activity(79. 06 ±4. 57) and NR2B mRNA expression (29. 13 ±1.39) in experimental control group (P<0.05). Withdrawal symptom score(12. 18 ±1.08) ,H2S content(33.00 ±5.38) ,CBS activity(67. 81 ±9. 37) and NR2B mRNA expression(23. 12 ± 1. 86) in high dose NBP group rats were lower than experimental control group (P < 0. 05). Conclusion NBP can reduce withdrawal symptoms of alcohol dependence rats,may be related to decreased expression of H2S/CBS system, and NR2B mRNA expression.

BACKGROUNDUnhygienic blood collection in the early 1990s led to blood-borne infections in Central China. This study aimed to estimate human immunodeficiency virus (HIV) co-infection with hepatitis C and B viruses (HCV and HBV) and their risk factors in a rural area of Shanxi Province with a history of commercial blood donation.
METHODSA cross-sectional study was conducted in 2004. All adult residents in the target area were invited to participate in the study. Face-to-face interviews were completed and blood specimens were tested for HIV, HCV, and HBV surface antigen (HBsAg).
RESULTSPrevalence rates of HIV, HCV, and HBsAg were 1.3% (40/3 062), 12.7% (389/3 062), and 3.5% (103/2982), respectively. Of the 40 HIV-positive specimens, 85% were HCV positive and 2.5% were HBsAg positive. The history of commercial blood donation was positively associated with HIV, HCV, and HIV/HCV co-infections, but was negatively associated with HBsAg seropositivity. Migration for employment in the last 5 years was positively related to HIV, HBsAg, and HIV/HCV co-infections. Univariate logistic analysis showed that illegal drug use, number of sex partners, extramarital sex behavior, commercial sex behavior, and condom use rate were not related to anti-HIV, anti-HCV, HBsAg seropositivity or their co-infections.
CONCLUSIONThe history of commercial blood donation was the main risk factor for HIV, HCV, and HIV/HCV co-infections in this former commercial blood donation area. HIV and HCV prevention and treatment interventions are important in this area.

Objective:To evaluate the clinical efficacy of omalizumab in the treatment of patients with chronic spontaneous urticaria accompanied by other allergic diseases.Methods:Clinical data were retrospectively collected from 74 patients, who were clinically diagnosed with chronic spontaneous urticaria and other allergic diseases, and received subcutaneous injections of omalizumab in the Department of Allergy, Tianjin Medical University General Hospital from June 2020 to September 2022. Types of allergic diseases, serum total IgE (tIgE) and allergen-specific IgE (sIgE) levels before treatment, treatment outcomes and adverse drug reactions were analyzed. Differences before and after treatment were assessed using paired t-test and Wilcoxon signed-rank sum test. Results:A total of 74 patients with chronic spontaneous urticaria were involved, including 29 with complicated allergic asthma (39.2%) , 61 with complicated allergic rhinitis (82.4%) , 6 with complicated atopic dermatitis (8.1%) , and 4 with food allergy (5.4%) . Before treatment, elevated serum tIgE or sIgE levels were observed in 44 (59.5%) patients. After the first omalizumab treatment, the urticaria control test (UCT) score significantly increased compared with that before treatment (16.00 [13.0.0, 16.00] vs. 6.00 [5.75, 9.00], Z = 7.39, P < 0.001) ; after 4 sessions of the omalizumab treatment, 82.5% (33/40) of the patients achieved complete control of urticaria symptoms or showed complete response. After omalizumab treatment, asthmatic attacks were decreased in 29 patients with allergic asthma, and asthma control test (ACT) scores significantly increased compared with those before treatment (21.07 ± 2.88 points [after the first treatment] vs. 18.48 ± 3.20 points [before treatment], t = 8.87, P < 0.001) ; among 61 patients with allergic rhinitis, global rhinitis symptom-based visual analog scale (VAS) scores (before treatment: 5.89 ± 1.29 points; after the first treatment: 3.28 ±1.46 points) and rhinoconjunctivitis quality of life questionnaire (RQLQ) scores (before treatment: 60.10 ± 20.53 points; after the first treatment: 37.26 ± 18.83 points) both significantly decreased after the first treatment ( t = 15.04, 10.01, respectively, both P < 0.001) , and rhinitis symptoms were relieved at the same time; skin itching was relieved in 4 patients with atopic dermatitis, and allergic symptoms after contact with food allergens were also relieved in the 2 patients with food allergy after omalizumab treatment. During the treatment, only 1 patient experienced erythematous swelling, induration, and pain at the injection site. Conclusions:In the treatment of chronic spontaneous urticaria accompanied by allergic diseases, the use of omalizumab not only effectively improved urticaria symptoms, but also well controlled allergic diseases, with a good safety profile. Multiple benefits may be achieved by the use of omalizumabin in patients with chronic spontaneous urticaria accompanied by other allergic diseases.
