A 69-year-old male with tinnitus, vertigo, and progressive hearing loss of left ear was admitted to our hospital. Head magnetic resonance imaging and computed tomography (CT) revealed swelling of multiple neck lymph nodes (LNs) invading the skull base, which involved left mastoid sinus/the eighth cranial nerve. Biopsy of the cervical LN demonstrated small-cell carcinoma (SCC). Whole body CT showed systemic lymphadenopathies (subclavian, para-aortic, and bilateral iliac LNs) and prostatic swelling with multiple pelvic masses. Needle biopsy of the prostate revealed SCC (Gleason score: 5+ 5). Immunohistochemically, neuron-specific enolase (NSE) and NCAM were detected in <10% and -100% of cancer cells, respectively. Despite SCC histology, prostate-specific antigen (PSA) and androgen receptor (AR) were also expressed in -20% and -70% of tumor cells, respectively. Serum PSA and NSE were 464 ng/ml and 12 ng/ml, respectively. After maximum androgen blockade (MAB) with leuprorelin/bicalutamide, the patient showed recovery of hearing loss, regression of cervical LNs (partial response), and decline of serum markers (PSA 7.38 ng/ml and NSE 3.7 ng/ml, respectively). As re-increase of PSA was observed after ten months, MAB menu was changed to leuprorelin/fultamide. Another four months later, the treatment was changed to docetaxel/ estramustine due to the appearance of systemic bone pain and recurrence of LN metastases. He is alive (39 months after diagnosis) with cancer. Widespread metastases at the time of diagnosis were compatible with SCC. However, this case was AR-positive and responded to androgen ablation, at least temporarily. Even though the initial symptoms are atypical for a prostatic carcinoma, SCC of prostate needs to be included as a rare differential diagnosis.

Tianma (Rhizoma gastrodiae) is the dried rhizome of the plant Gastrodia elata Blume (Orchidaceae family). As a medicinal herb in traditional Chinese medicine (TCM) its functions are to control convulsions, pain, headache, dizziness, vertigo, seizure, epilepsy and others. In addition, tianma is frequently used for the treatment of neurodegenerative disorders though the mechanism of action is widely unknown. Accordingly, this study was designed to examine the effects of tianma on the proteome metabolism in differentiated human neuronal SH-SY5Y cells to explore its specific effects on neuronal signaling pathways. Using an iTRAQ (isobaric tags for relative and absolute quantitation)-based proteomics research approach, we identified 2390 modulated proteins, out of which 406 were found to be altered by tianma in differentiated human neuronal SH-SY5Y cells. Based on the observed data, we hypothesize that tianma promotes neuro-regenerative signaling cascades by controlling chaperone/proteasomal degradation pathways (e.g. CALR, FKBP3/4, HSP70/90) and mobilizing neuro-protective genes (such as AIP5) as well as modulating other proteins (RTN1/4, NCAM, PACSIN2, and PDLIM1/5) with various regenerative modalities and capacities related to neuro-synaptic plasticity.
