Objective To establish an initial diagnostic method for β-thalassemia (BT) using a double antibody sandwich ELISA approach. Methods The hybridoma producing monoclonal antibodies against anti-HbF were screened using a trailing count method. The mAbs were evaluated through ELISA,modified immunocytochem-istry,and Western blot analysis. A double antibody-sandwich ELISA assay was established by labeling the pairs of mAbs with ALP using the glutaral method,and this detection system was used to analyze 40 serum samples. Results The results demonstrate the successful generation of nine hybridoma cell lines capable of secreting highly active anti-HbF monoclonal antibodies (mAbs). Specifically,four mAbs (3F7,4G1,6C1,and 9H7) exhibited exclusive reactivity towards HbF without any cross-reactivity with hemoglobin variants (HbA and HbA2). These four HbF-specific mAbs displayed exceptional specificity and sensitivity,with a maximum titer of 1:256000 and the highest affinity constant (Ka) recorded at 2.36×108 L/mol. Among these mAbs,optimal antibody pairing was achieved using capture antibody 3F7 in conjunction with ALP-4G1 for the development of a sandwich ELISA detec-tion method. By employing this approach,fetal and healthy human blood samples were successfully quantified for HbF levels with an impressive detection sensitivity reaching up to 80%. Conclusion This sandwich ELISA dem-onstrated precise quantification of HbF levels,making it suiTab.for both research and diagnostic purposes in the field of β-thalassemia.

Allergic rhinitis (AR) is a global health problem that causes major illnesses and disabilities worldwide. Epidemiologic studies have demonstrated that the prevalence of AR has increased progressively over the last few decades in more developed countries and currently affects up to 40% of the population worldwide. Likewise, a rising trend of AR has also been observed over the last 2–3 decades in developing countries including China, with the prevalence of AR varying widely in these countries. A survey of self-reported AR over a 6-year period in the general Chinese adult population reported that the standardized prevalence of adult AR increased from 11.1% in 2005 to 17.6% in 2011. An increasing number of original articles and imporclinical trials on the epidemiology, pathophysiologic mechanisms, diagnosis, management and comorbidities of AR in Chinese subjects have been published in international peer-reviewed journals over the past 2 decades, and substantially added to our understanding of this disease as a global problem. Although guidelines for the diagnosis and treatment of AR in Chinese subjects have also been published, they have not been translated into English and therefore not generally accessible for reference to non-Chinese speaking international medical communities. Moreover, methods for the diagnosis and treatment of AR in China have not been standardized entirely and some patients are still treated according to regional preferences. Thus, the present guidelines have been developed by the Chinese Society of Allergy to be accessible to both national and international medical communities involved in the management of AR patients. These guidelines have been prepared in line with existing international guidelines to provide evidence-based recommendations for the diagnosis and management of AR in China.

Objective To observe the therapeutic effects of medicated thread moxibustion of traditional Zhuang nationality medicine combined with Shugan Jianpi Decoction for cirrhosis ascites. Methods Sixty patients with cirrhosis ascites were randomly divided into observation group and control group by random number method, 30 cases in each group. The treatment group received medicated thread moxibustion of traditional Zhuang nationality medicine combined with Shugan Jianpi Decoction and regular Western medicine; while control group only received regular Western medicine. Two weeks was a course of treatment. The liver function (ALT, AST, TBIL, ALB, A/G), ascites integral changes and improving time of main clinical symptoms (abdominal distension, pain, anorexia, fatigue) were observed. The clinical curative effects of two groups were evaluated with 3 months of follow-up. Results The liver function (ALT, AST, TBIL, ALB, A/G) in the treatment group after treatment was significantly improved, and the ascites integral decreased, which was better than the control group, with statistical significance (P<0.05). The improving time of main clinical symptoms in the treatment group was significantly shorter than the control group (P<0.05);The clinical effective rate was 90.00%(27/30) in the treatment group and 76.67% (23/30) in the control group, with statistical significance (P<0.05). Conclusion Medicated thread moxibustion of traditional Zhuang nationality medicine combined with Shugan Jianpi Decoction has good efficacy for cirrhosis ascites.
