A 19-year-old female patient received risperidone 3 mg twice daily for schizophrenia. She did not have nipple discharge before taking the drug. After taking the drug, nipple discharge occurred intermittently. One year later, a mass with pain in the right breast was found, which could not be alleviated after treatments with Rupi Sanjie capsules (乳癖散结胶囊), cefdinir, ibuprofen, rifampicin, and isoniazid and continued to increase, accompanied by bilateral knee pain, nodular erythema and tenderness of lower limbs. Laboratory tests showed white blood cell count 18.4×10 9/L and serum prolactin 37.42 μg/L. Ultrasonography of the right breast showed a 13.2 cm×11.0 cm×3.0 cm area low echo with unclear boundary, local fluidity, and abundant blood flow signals around. Granulomatous lobular mastitis of right breast (abscess stage) and hyperprolactiemia was diagnosed. After excluding physiological and pathological reasons, it was considered that risperidone caused hyperprolactinemia, which then induced granulomatous mastitis. However, risperidone could not be stopped without the guidance of a specialist, so only abscess incision, drainage, debridement, anti-infection, and anti-inflammatory were given. Purulent secretions gradually decreased, pain alleviated, and erythema of lower limbs partially subsided. Then risperidone dose was adjusted to 2 mg twice daily under the guidance of her psychiatrist. The serum prolactin level decreased (28.36 μg/L). At 1 year of follow-up, granulomatous mastitis did not recur.

Objective:To study the effect of Shenqi Fuzheng injection combined with interferon-α (IFN-α) on the expression of STAT1 gene in hepatocellular carcinoma cells,and to elucidate its mechanism of IFN-α synergistic effect.Methords:The effect of IFN-α injection alone or combined with Shenqi Fuzheng injection on the proliferation of MHCC97-L cells was detected by MTT assay.IFN-α was detected by Real-time PCR and Western-blot respectively.The expression of STAT1 mRNA and protein in the experimental group,the negative control group (NaCl) and the blank control group were determined,and the effect of Shenqi Fuzheng injection on the transcription and expression of STAT1 was determined.The expression of STAT1 in lentiviral vector MTT assay was used to detect the effect of IFN-α alone or in combination with Shenqi Fuzheng injection on the STAT1 gene silencing cells.The expression of STAT1 was detected by RT-PCR and Western-Blot in MHCC97L cells.Strain,on cell proliferation.Results:Compared with IFN-α alone,Shenqi Fuzheng injection combined with IFN-α enhanced the inhibitory effect of IFN-α on MHCC97-L (P＜0.01) and up-regulated the expression of STAT1mRNA and protein (P＜0.05).Successfully constructed the STAT1 gene silent in the MHCC97-L cell line.There was no significant difference in the inhibition rate of MHCC97-L between Shenqi Fuzheng injection and IFN-α (P＞0.05).Conclusion Shenqi Fuzheng Injection can up-regulate the expression of STAT1 in human hepatocellular carcinoma cell line MHCC97-L,so as to increase the effect of IFN-α.
