Effects of BL 23 (Shenshu) acupuncture on serum cytokine levels in healthy adults: A randomized double-blind sham-controlled phase 1 study.

The purpose of this study was to evaluate the safety and efficacy of BL 23 (Shenshu) acupuncture on serum cytokine levels. Sixteen healthy adults were randomized into the BL 23 acupuncture group or pseudo-acupuncture group and changes of serum cytokines were analyzed. The changes in IL-13, TNF-α, and GM-CSF levels were different between the BL 23 acupuncture group and pseudo-acupuncture group (P < 0.05). No adverse events associated with acupuncture were observed. In conclusion, BL 23 acupuncture can suppress immune responses via decreases in TNF-α and suppression of increases in IL-13 and GM-CSF. This study elucidated some of the mechanisms of the acupuncture effect.

[A case of gastric stenosis due to primary gastric malignant lymphoma during administration of R-CHOP].

A 59-year-old man presented to his general practitioner(GP)complaining of gastric discomfort. Endoscopy revealed an irregular ulcerative region from the gastric lower body to the pylorus. The GP sent the patient to our hospital. With a diagnosis of diffuse large B-cell lymphoma(DLBCL)based on biopsy findings, the patient was treated with R-CHOP chemotherapy. After two courses of this regimen, the patient had vomiting on several occasions. A computed tomography(CT)examination and endoscopy showed that the tumor decreased, but a tight stenosis was located at the pylorus. Because he had trouble continuing chemotherapy, a gastrojejunal bypass operation was performed. The patient did not have vomiting and was able to take meals. After this chemotherapy, CT examination and biopsy findings confirmed that the DLBCL and lymph node metastases had disappeared. Gastrojejunal bypass is expected to be an effective method for treating gastric stenosis during the chemotherapy of DLBCL.

Role of thrombin in interleukin-5 expression from basophils.

Interleukin-5 (IL-5) plays a key role in the pathogenesis of bronchial asthma. Thrombin is a procoagulant factor that has been also reported to participate in the inflammatory response by stimulating the secretion of cytokines. Interaction of inflammatory cells with airway epithelial cells may also promote the secretion of cytokines. However, the role of thrombin and cell-to-cell interaction in pathogenesis of allergic inflammation is unclear. In this study, we evaluated the role of thrombin and cell-to-cell interaction in the secretion of IL-5 from basophils. The human basophil cell line KU-812 was used in the assays. Thrombin and co-culture with alveolar epithelial cells significantly stimulated the secretion of IL-5 from KU-812 cells as compared to controls. Secretion of IL-5 was synergistically stimulated when KU-812 cells were incubated in the presence of both thrombin and alveolar epithelial cells. Co-culture of KU-812 cells with epithelial cells significantly increased the expression of tissue factor, an activator of coagulation activation, in a cell dose-dependent manner. Secretion of IL-5 from KU-812 basophils co-cultured with epithelial cells was significantly inhibited by LY294002, an inhibitor of phosphatidylinositol 3-kinase. These results suggest that thrombin and cell interaction with lung epithelial cells may augment the inflammatory response in allergic diseases by stimulating the secretion of IL-5 from basophils.

Moxibustion, an alternative therapy, ameliorated disturbed circadian rhythm of plasma arginine vasopressin and urine output in multiple system atrophy.

Previously no alternative therapy approach has been made to ameliorate disturbed circadian arginine vasopressin rhythm (C-AVP-R) in multiple system atrophy (MSA). A 65-year-old man with MSA showed loss of C-AVP-R and nocturnal polyuria. We performed moxibustion at specific acupuncture points on the bladder and inside the feet, once a day, 3 times a week, for 6 months. After the treatment, his C-AVP-R appeared to be normal, and the nocturnal urine output decreased to 75% (p<0.01). Together with the previous studies, it seems possible that somatic warm stimulation by moxibustion in specific points might have facilitated AVP secretion in this patient.
