The purified elementary bodies of C. pneumoniae TW-183 were used for immunization of male BALB/c mice, the spleen cells of these mice were fused with SP2/0 cells and the hybrid cells were cloned by limiting dilution. One clone that secreted the C. pneumoniae monoclonal antibody (Cpn-McAb) stably was obtained finally. The Cpn-McAb belonged to IgG2b class and anti-Cpn-MOMP; the outcome of micro-immunofluorescence showed its weak cross reaction with the C. psittaci elementary body but it has no cross reaction with C. trachoma elementary body. It has the same speciality of the imported Cpn-McAb. For the evaluation of Cpn-McAb, the peripheral blood mononuclear cell specimens of 454 patients were detected by self-made Cpn-McAb and imported Cpn-McAb at the same time. The positive rates of Cpn-antigen were 53.3% for self-made Cpn-McAb and 52.6% for imported Cpn-McAb,showing high concordance between them (Kappa=0.714). The results showed that self-made Cpn-McAb has almost the same high specificity and sensitivity as imported Cpn-McAb, so the self-made Cpn-McAb may replace imported Cpn-McAb to detect Cpn specific antigen and be helpful to diagnosing and treating the clinical diseases associated with Cpn infection.

Objective:To observe the clinical effect of modified Shishi Niubangzi Decoction combined with strengthening muscle-waist exercise on lumbar disc herniation (LDH).Methods:Randomized controlled trial. A total of 60 patients with LDH admitted to the Pinggu Hospital, Beijing Traditional Chinese Medicine Hospital, were enrolled as the research objects between September 2020 and September 2021. According to the random number table, they were randomly divided into the treatment group and control group, 30 in each group. Both groups were given routine basic treatments (strengthening tendons-waist exercise and three-position six-step manipulation). On this basis, the treatment group was treated with modified Shishi Niubangzi Decoction, while the control group was treated with non-steroidal anti-inflammatory drugs (ibuprofen codeine sustained-release tablets). Both groups were treated for 4 weeks. The responsive rates, back pain intensity, leg pain and numbness by Visual Analogue Scale (VAS) and lumbar function by Oswestry Disability Index (ODI), and Japanese Orthopaedic Association (JOA) were compared between the two groups.Results:The response rate of treatment group was significantly higher than that of control group (93.3% vs. 73.3%; χ2=4.32, P=0.038). After treatment, scores of JOA (subjective symptoms, signs, activities of daily living) in the treatment group were significantly higher than those in the control group ( t=3.86, 2.71, 2.21, P<0.05). After treatment, scores of back pain (2.12±0.21 vs. 3.02±0.32, t=12.88), leg pain (2.04±0.64 vs. 2.64±0.66, t=3.58), lower limb numbness (1.75±0.24 vs. 2.41±0.70, t=4.89) in the treatment group were significantly lower than those in the control group ( P<0.01). At 1 week and 1 month after treatment, ODI scores in treatment group were significantly lower than those in control group ( t=10.22, 5.59; P<0.05). Conclusion:The modified Shishi Niubangzi Decoction combined with strengthening tendons-waist exercise can improve responsive rates, improve lumbar pain and function in LDH patients.

Mongolian medicine (MM) is an important part of Mongolian culture. Exploration of MM can play a crucial role in the prevention and treatment of various diseases and can help provide better health care globally. In this article, we gave a brief introduction to the origin and development of MM, the theoretical system of MM, the principles of Mongolian materia medica formula, the modern research on Mongolian materia medica and the quality control of Mongolian materia medica. The present situation and outlook of MM were also discussed.
