Chinese Herbal Medicine Adjusting Brain Microenvironment via Mediating Central Nervous System Lymphatic Drainage in Alzheimer's Disease.

Due to its complex pathogenesis and lack of effective therapeutic methods, Alzheimer's disease (AD) has become a severe public health problem worldwide. Recent studies have discovered the function of central nervous system lymphatic drainage, which provides a new strategy for the treatment of AD. Chinese herbal medicine (CHM) has been considered as a cure for AD for hundreds of years in China, and its effect on scavenging ß-amyloid protein in the brain of AD patients has been confirmed. In this review, the mechanism of central nervous system lymphatic drainage and the regulatory functions of CHM on correlation factors were briefly summarized. The advances in our understanding regarding the treatment of AD via regulating the central lymphatic system with CHM will promote the clinical application of CHM in AD patients and the discovery of new therapeutic drugs.

[Experience from four dimensions application of classic formulas for treatment of dysmenorrhea].

The application of classic formulas from Shanghan Zabing Lun has a long history in treatment of dysmenorrhea. However, the understanding on how to use classic formula in treatment of dysmenorrhea is still insufficient in the traditional Chinese medicine (TCM), mainly limited to syndrome differentiation and the formula-syndrome correlation. The treatment method of syndrome differentiation is flexible and changeable, but the process is tedious and difficult to copy. In addition, its experience is not easy to summarize and pass on, and it is difficult for beginners to comprehend the essence. Formula-syndrome correlation method is accurate, quick acting, but subjective, too mechanical, and will have obvious side effects in case of prescription mistakes. For complex diseases or when suffering from a variety of diseases, the efficacy of formula-syndrome correlation method is not so obvious. By analyzing the advantages and limitations of these two methods, the author has created a four-dimensional therapy which combines the advantages of these two, from four dimensions including disease differentiation, syndromes differentiation, time differentiation, and constitution differentiation in clinical application for dysmenorrheal. Its clinical curative effect is satisfactory. Four-dimensional therapy is a way of thinking, to guide clinicians for accurate diagnosis and precisely choosing drugs; meanwhile, the personalized health guidance is given according to different constitutions and different seasons, which also has certain significance to treat the undiseased.

[Guiding Significance of "Mistreatment by Warming Therapy" in Treatment of Non-small Cell Lung Cancer].

"Mistreatment by warming therapy" refers to various symptoms/syndromes caused by improper use of fire methods mentioned in Treatise on Febrile Diseases, which are similar to damaged yin induced fire-heat syndrome (injury of yin, consumption of qi, loss of yin, consumption of body fluid) manifested after radiotherapy and/or chemotherapy in modern clinics. Better efficacy was obtained in treating various symptoms/syndromes by using nourishing yin purging fire method. In this paper authors focuses on exploring guiding significance of using "Mistreatment by warming therapy" in treating non-small cell lung cancer (NSCLC).

[Effect of Zhixin Formula on Gliocyte Protein Expressions, TLRs and NF-κB in Bone Cancer Pain Model Rats].

OBJECTIVE: To explore the analgesic effect of Zhixin Formula (ZF) and its effects on spinal glial fibrillary acidic protein (glial fibillary acidic protein, GFAP, a marker of astrocyte) , CD11b (a maker of microglia), Toll like receptors (TLR2 and TLR4) and nuclear factor κB (NF-κB) in bone cancer pain model rats. METHODS: Totally 20 male SD rats were randomly divided into the blank control group and the bone cancer pain group, 10 in each group. The bone cancer pain model was induced by injecting ascites tumor fluid containing 3 x 10(3) Walker256 cell line from the left tibia. Ethological tests, X-ray test, and HE staining were performed to confirm a successful modeling. After model was successfully established, 70 male SD rats were randomly divided into seven groups, 10 in each group: the blank control group, the bone cancer pain group (as the model group), the Western medicine (WM) group (Tramadol Hydrochloride), the high dose ZF group, the middle dose ZF group, the low dose ZF group, and the Chinese medicine (CM) group (Wulin Zhitong Capsule). Fourteen days after modeling, rats in the high, middle, and low dose ZF groups were administrated by gastrogavage with 9, 4.5, and 2.25 g/kg ZF water condensed preparation respectively, once a day for seven consecutive days. On day 21 MS typical protein expressions including GFAP, CD11b, TLR (2,4) and NF-κB from cornu dorsal medullae spindis L4-L5 were detected by immunohistochemistry, reverse transcription-polymerase chain reaction (RT-PCR) and Western blot. RESULTS: Compare with the blank control group, increased weight in the model group was slow and showed a decreasing trend (P < 0.01), spontaneous ambulatory pain score (SAPS) obviously increased (P < 0.01), paw withdrawal threshold (PWT) obviously decreased in the model group (P < 0.05, P < 0.01). Results of lateral tibial X-ray and HE staining showed obvious changes and damage occurred in bone structures of rats in the model group. Immunohistochemistry showed that GFAP expression significantly increased in the model group (P < 0.05). Protein levels of NF-κB also significantly increased in the model group (P < 0.05). Compared with the model group, CD11b expressions obviously decreased in the middle and high dose ZF groups (P < 0.01). Meanwhile, protein expressions of TLR2 and TLR4, as well as NF-κB also obviously decreased (P < 0.05). CONCLUSION: ZF had analgesic effect, which might be probably related to inhibiting proliferation and activation of gliocytes, as well as activation of TLRs and NF-κB.

[Effect-of Angong Niuhuang Pill on Th1/Th2 of cerebral infarction patients of phlegm-heat obstructing orifices in China and Indonesia].

OBJECTIVE: To observe the effect of Angong Niuhuang Pill (ANP) on Thl/Th2 in cerebral infarction patients and to explore the mechanism of phlegm-heat obstructing orifices. METHODS: Re- cruited were 30 cerebral infarction patients of phlegm-heat obstructing orifices syndrome (PHOOS) both in China and Indonesia. They were assigned to 4 groups according to the use of ANP, the Chinese treatment group, the Indonesia treatment group, the Chinese control group, and the Indonesia control group. Patients in the two control groups received conventional treatment, while those in the two treatment group additionally took ANP for 30 successive days. Their adverse reactions were observe, and levels of INF-γ and IL-4 were detected. RESULTS: The INF-γ level and the INF-γ/IL-4 ratio significantly decreased, and the IL-4 level increased after treatment in the four groups with statistical difference (P < 0.05). Compared with the control group after treatment in the same country, the INF-γ level and the INF-γ/IL-4 ratio were lower, and the IL-4 level was higher in the two treatment groups (P < 0.05). Compared with the two Chinese groups, the INF-γ level and the INF-γ/IL-4 ratio were higher, and the IL-4 level was lower in the two Indonesian groups (P < 0.05). There was no statistical difference in the post-treatment indices between the two treatment groups. CONCLUSIONS: ANP had moderating effect on Th1/Th2 in cerebral infarction pa- tients. Cerebral infarction patients of PHOOS might exist certain relation with Th1/Th2.

[Research on the relationship between chinese medical syndrome types and Th1/Th2 in bronchioloalveolar carcinoma by thoracoscopic technique].

OBJECTIVE: To study the relationship between Chinese medical syndrome types of bronchioloalveolar carcinoma (BAC) and Th1/Th2. METHODS: Totally 60 BAC patients were syndrome typed as qi and yin deficiency syndrome (QYDS) and qi stagnation and phlegm-blood stasis syndrome (QSPSS), 30 cases in each group. Meanwhile, 30 subjects with benign pulmonary nodules were recruited as the control group. The contents of interferon-gamma (INF-gamma), interleukin 4 (IL-4), IL-2, and IL-5 were detected using thoracoscopic technique. RESULTS: As for Th1 (INF-gamma and IL-2), it was ranked from high to low as the control group > the QSPSS group > the QYDS group (P < 0.05). As for Th2 (IL-4 and IL-5), it was ranked from high to low as the QYDS group > the QSPSS group >the control group (P < 0.05). As for Th1/Th2 (INF-gamma/lL-4, IL-2/IL-5), it was ranked from high to low as the control group > the QSPSS group >the QYDS group (P < 0.05). CONCLUSIONS: Compared with the tissue of benign nodules, Th1 function in tumor tissue of BAC patients was weaker and Th2 function stronger. Chinese medical syndrome types of BAC had correlation with Th1/Th2. Patients of excess syndrome had stronger immunity with Th1/Th2 shifting left,while those of deficiency syndrome were predispose to humoral immunity with Thl/Th2 shifting right.

[Observation on therapeutic effect of acupuncture in the treatment of German hypertension patients].

OBJECTIVE: To observe the clinical efficacy of acupuncture in the treatment of hypertension patients. METHODS: A total of 80 out-patients and in-patients with primary hypertension were randomly and equally divided into acupuncture group and medication group. Patients of the acupuncture group were treated with acupuncture stimulation of Fengchi (GB20), Qu-chi (LI 11), Taichong (LR 3), etc. for 30 min, combined with Xingjian (LR 2), Xiaxi (GB43) for hyperactivity of the liver-yang, with Ganshu (BL 18) and Fuliu (KI 7) for severe phlegm-damp, and with Guanyuan (CV 4) and Shenshu (BL23) for deficiency of both yin and yang, once per day, continuously for one month except weekends. In addition, patients of the medication group were ordered to take Diovan (80 mg) once daily, continuously for 30 days. Both casual blood pressure (CBP) and ambulatory blood pressure (ABP) were detected by using an auscult-type baumanometer and a dynamic blood monitor, respectively. RESULTS: Of the two 40 cases in the medication and acupuncture groups, 18 (45.0%) and 27 (67.5%) experienced marked improvement in the reduction of blood pressure, 14 (35.0%) and 11 (27.5%) were improved, 8 (20.0%) and 2 (5.0%) failed, with the effective rates being 80.0% and 95.0%, respectively. The therapeutic effect of the acupuncture group was significantly superior to that of medication group in improving hypertension (P < 0.05). CONCLUSION: Acupuncture is superior to Diovan in relieving hypertension.
