An Effective Treatment of Perimenopausal Syndrome by Combining Two Traditional Prescriptions of Chinese Botanical Drugs.

Ethnopharmacological relevance: Two types of traditional Chinese formulas of botanical drugs are prescribed for treating perimenopausal syndrome (PMS), a disorder in middle-aged women during their transition to menopause. One is for treating PMS as kidney deficiency (KD) due to senescence and declining reproductive functions, and the other is for treating it as liver qi stagnation (LQS) in association with stress and anxiety. Despite the time-tested prescriptions, an objective attestation to the effectiveness of the traditional Chinese treatment of PMS is still to be established and the associated molecular mechanism is still to be investigated. Materials and methods: A model for PMS was generated from perimenopausal rats with chronic restraint stress (CRS). The effectiveness of traditional Chinese formulas of botanical drugs and a combination of two of the formulas was evaluated based on 1H NMR plasma metabolomic, as well as behavioral and physiological, indicators. To investigate whether the formulas contained ligands that could compensate for the declining level of estrogen, the primary cause of PMS, the ligand-based NMR technique of saturation transfer difference (STD) was employed to detect possible interacting molecules to estrogen receptors in the decoction. Results: Each prescription of the classical Chinese formula moderately attenuated the metabolomic state of the disease model. The best treatment strategy however was to combine two traditional Chinese formulas, each for a different etiology, to adjust the metabolomic state of the disease model to that of rats at a much younger age. In addition, this attenuation of the metabolomics of the disease model was by neither upregulating the estrogen level nor supplementing an estrogenic compound. Conclusion: Treatment of PMS with a traditional Chinese formula of botanical drugs targeting one of the two causes separately could ameliorate the disorder moderately. However, the best outcome was to treat the two causes simultaneously with a decoction that combined ingredients from two traditional prescriptions. The data also implicated a new paradigm for phytotherapy of PMS as the prescribed decoctions contained no interacting compound to modulate the activity of estrogen receptors, in contrast to the treatment strategy of hormone replacement therapy.

Clinical observation on curative effect of dissolving phlegm-stasis on 50 cases of knee osteoarthritis.

OBJECTIVE: To observe the curative effect of dissolving phlegm-stasis on knee osteoarthritis. METHODS: The 100 patients with knee osteoarthritis were randomly divided into two groups. The 50 patients in the treatment group orally took Chinese medicine while the other 50 patients in the control groups orally took Votalin and Vitamin C for one week as a course of treatment. At the end of 2-week treatment, analytic comparison was carried in evaluate the curative effect and the changes in total score of symptoms before and after treatment between the two groups. RESULTS: The total score of symptoms after treatment was significantly lower than that before treatment in both groups (P<0.01, P<0.05). The total score after treatment of patients with X-ray grade I and II in the treatment group was more obviously reduced as compared to the control group (P<0.05). The remarkably effective rate after treatment of patients with X-ray grade I and II in the treatment group was also higher than that in the control group (P<0.05). CONCLUSION: The treatment of knee osteoarthritis with dissolving phlegm-stasis can effectively improve the clinical symptoms.

The Metabolomic Rationale for Treating Perimenopausal Syndrome as Kidney Deficiency.

BACKGROUND: Traditional Chinese medicine (TCM) typically attributes the etiopathogenesis of perimenopausal syndrome (PMS) to kidney deficiency in the TCM stratification system for diagnosis. However, the molecular basis of this classical attribution remains to be investigated. Aim of the Study. By unraveling the responses to TCM treatment for kidney deficiency, the metabolomic link between PMS and kidney deficiency can be evaluated for in-depth understanding of the mechanism of TCM treatment and development of better treatment protocols. MATERIALS AND METHODS: With naturally aged rats as a model for PMS, the metabolomic response to TCM treatment for kidney deficiency was investigated by 1H NMR. RESULTS: 1H NMR metabolomic evidence of plasma samples demonstrates that treatments with two classical TCM prescriptions for kidney deficiency, decoctions of Yougui and Zuogui, result in modulating the metabolic state of the disease model towards that of rats of younger age. CONCLUSION: The data support the notion that kidney deficiency is responsible, in part at least, for PMS, and the relevant prescriptions are helpful in dampening the changes in the body's metabolic states to alleviate symptoms of the disorder.

Langerhans cell sarcoma arising from antecedent langerhans cell histiocytosis: A case report.

RATIONALE: Langerhans cell sarcoma (LCS) is a rare, high-grade neoplasm characterized by overtly malignant cytologic features and a poor prognosis. Herein, we present a rare case of langerhans cell histiocytosis (LCH) that later transformed into langerhans cell sarcoma 11 months after the benign mass was excised from soft tissue in the right groin. PATIENT CONCERNS: A 41-year-old patient who presented with a mass in the right groin for 3 years earlier after being bitten by ants. DIAGNOSES: The patient was diagnosed with langerhans cell sarcoma arising from antecedent langerhans cell histiocytosis. INTERVENTIONS: The patient underwent with 6 cycles of a modified etoposide, cyclophosphamide, vindesine, dexamethasone (E-CHOP) regimen. OUTCOMES: The patient is currently receiving follow-up care. LESSONS: LCH transformed into LCS is a rare case. E-CHOP as an effective first-line therapy to treat LCS cases, but, the mechanism is unclear. Due to their rarity, further data on clinical outcomes are necessary to establish the optimal treatment strategy for LCS.

Saikosaponin A attenuates perimenopausal depression-like symptoms by chronic unpredictable mild stress.

Accumulating studies have shown that a traditional Chinese decoction Chaihu-Shugan-San produced the antidepressant-like effects in rodents including in perimenopausal. Previous studies and our preliminary study indicated that saikosaponin A, one of the main constituents of Chaihu-Shugan-San, enhanced brain-derived neurotrophic factor (BDNF) expression in rats. Herein, this study aimed to evaluate the antidepressant-like effects of saikosaponin A in perimenopausal rats exposed to chronic unpredictable mild stress (CUMS). The sucrose preference test, novelty-suppressed feeding test and forced swimming test were performed after administration of saikosaponin A for 4 weeks. Serum corticotrophin-releasing hormone (CRH), adrenocorticotropic hormone (ACTH) and corticosterone levels, as well as hypothalamus CRH and hippocampal glucocorticoid receptor were measured. In addition, pro-inflammatory cytokines such as interleukin-1beta (IL-1ß), interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α) in the hippocampus were detected for evaluation of the neuroinflammation. Further, BDNF levels and its receptor TrkB were also determined. Our results indicated that four-week treatment with saikosaponin A increased sucrose preference, decreased latency to feed in the novelty-suppressed feeding test and reduced the immobility time in the forced swimming test. In addition, saikosaponin A restored the dsyregulation of HPA axis and neuroinflammation in rats exposed to CUMS. Moreover, saikosaponin A promoted BDNF-TrkB signaling in the hippocampus. This study demonstrates that saikosaponin A produced the antidepressant-like effects in rats, which may be mediated by restoration of neuroendocrine, neuroinflammation and neurotrophic systems in the hippocampus during perimenopausal.

The antidepressant-like effects of Chaihu Shugan San: Dependent on the hippocampal BDNF-TrkB-ERK/Akt signaling activation in perimenopausal depression-like rats.

Chaihu Shugan San (CSS), a traditional Chinese medicine formula, has been used to treat depression for hundreds of years. Recently, the antidepressant-like mechanism of CSS has been increasingly evaluated and demonstrated. However, there are few studies focused on the involvement of the neurotrophic system in mediating the antidepressant-like effects of CSS. Considering the high prevalence of perimenopausal depression around the world, the goal of the present study was to determine whether brain-derived neurotrophic factor (BDNF) signaling is required for the antidepressant-like effects of CSS in perimenopausal depressive-like rats. The results indicate that CSS reverses depressive-like behaviors and attenuates the downregulation of BDNF in the hippocampus of perimenopausal rats exposed to chronic unpredictable mild stress (CUMS). We found that the TrkB antagonist K252 not only blocks the effects of CSS on behavioral improvement but also abolishes the activation of CSS in BDNF-TrkB signaling. As a result, the downstream targets of BDNF signaling, such as the ERK and Akt pathways, are significantly inhibited by K252a. Furthermore, CSS increases hippocampal neurogenesis, while K252a fully prevents this action. In conclusion, the present results demonstrate that the activation of the hippocampal BDNF-TrkB-ERK/Akt signaling pathway is required for the antidepressant-like effects of CSS on the depressive-like state during perimenopause. Additionally, this study also demonstrates that neurogenesis is required for the effects of antidepressants in aging perimenopausal animals and provides fundamental evidence for the clinical application of CSS.

Sarsasapogenin reverses depressive-like behaviors and nicotinic acetylcholine receptors induced by olfactory bulbectomy.

Cholinergic signalling in the hippocampus may contribute to the aetiology of mood regulation. Antidepressants can reverse the increase in acetylcholinesterase (AChE) activity induced by olfactory bulbectomy. The activation of nicotinic acetylcholine receptors (nAChRs) also alleviates the symptoms of depression. This study advances the development of sarsasapogenin, which interacts with cholinergic signalling and has a favourable antidepressant profile in olfactory bulbectomised (OB) rats. We examined OB-induced changes in cholinergic signalling, as well as AChE, α4-nAChR, and α7-nAChR expression in the hippocampus. The results indicate that abnormal cholinergic signalling in the hippocampus contributes to the development of depression in the OB rat model. This depression may be alleviated following treatment with sarsasapogenin.
