Characteristics of traditional Chinese medicine syndromes in post-stroke depression
Hui HAN
Zhong Xi Yi Jie He Xue Bao , 2010,
Abstract: Objective: To explore the main characteristics of syndromes in traditional Chinese medicine (TCM) in post-stroke depression (PSD) and to provide basis for treatments with TCM herbs.Methods: According to diagnostic criteria of PSD, stroke patients and depression patients from Department of Neurology, First Affiliated Hospital, Anhui University of Traditional Chinese Medicine were assigned into cerebral stroke group (150 cases), depression group (151 cases) and PSD group (123 cases). Neuropsychological assessments and imaging and biochemical analyses were conducted. TCM syndrome differentiation for these diseases was performed. We also determined the characteristics of TCM syndromes of PSD, relative risk of the syndromes and their correlations with ages as well.Results: Scores of qi stagnation and blood stasis, liver qi depression, and transformation of fire due to qi stagnation in PSD group were significant higher than those in cerebral stroke group (P<0.05, P<0.01). In cerebral stroke group, majority of the patients displayed one syndrome, while in PSD and depression groups, the patients had three or more syndromes. Of these syndromes, the incidence rate of syndrome of liver qi depression complicated with transformation of fire due to qi stagnation or flaring of fire due to yin deficiency was high. The syndrome of liver qi depression occurred much more frequently in PSD group and depression group than in cerebral stroke group (P<0.05, P<0.01). The logistic regression analysis showed that the syndrome of qi stagnation and blood stasis had high relative risk to PSD. The syndrome of deficiency of heart and spleen was positively correlated with age in cerebral stroke group.Conclusion: The main TCM syndromes of PSD and depression are qi stagnation and blood stasis, liver qi depression, and transformation of fire due to qi stagnation. The syndrome of deficiency of heart and spleen is closely related to age among the stroke patients. The syndrome of qi stagnation and blood stasis serves as an independent risk factor for PSD. The more complicated the syndromes are, the more serious depression becomes.

Abstract: OBJECTIVE: To establish a rat model of diabetes-associated cerebral ischemia due to qi and yin deficiency and blood stasis, and to investigate the effects of Radix Ginseng, Rhizoma Chuanxiong, Rhizoma Polygonati Odorati and Rhizoma Polygonati Sibirici Granule (Shenxiong Yujing Granule), which has the function of strengthening qi, nourishing yin, and activating blood, on proliferation, differentiation and survival of neural cells in rats with diabetes-associated cerebral ischemia. METHODS: Rats were divided into sham-operation, diabetes plus ischemia reperfusion injury model, Shenxiong Yujing Granule and Radix Ginseng and Rhizoma Chuanxiong Granule (Shenxiong Granule) groups with 20 rats in each. The 5-bromo-2′-deoxyuridine (BrdU) incorporation assay and immunohistochemical method were used to investigate the proliferation, differentiation and survival of neural cells in dentate gyrus of rats with diabetes-associated cerebral ischemia. RESULTS: The number of newly proliferating cells in subgranular zone of dentate gyrus was increased in the model group, but there was no significant difference compared with 7 day treatment with Shenxiong Yujing Granule. Shenxiong Yujing Granule significantly increased the survival rate and promoted the differentiation of newly proliferating neurons after 21-day treatment (P<0.01). In addition, the beneficial effect of Shenxiong Yujing Granule was considerably greater than that of the Shenxiong Granule (P<0.01). CONCLUSION: Shenxiong Yujing Granule can increase the survival rate and promote the differentiation of newly proliferating neurons in rats with diabetes-associated cerebral ischemia of dual deficiency of qi and yin and blood stasis obstructing the collaterals. The effect is greater than that of Shenxiong Granule.

Hui Li,Baoshan Han
Chinese Science Bulletin , 2003, DOI: 10.1007/BF03187056
Abstract: DNA is a kind of promising molecule as nano-lead to build or connect nano-devices due to its stable linear structure and certain conductivity. Many methods have been applied to constructing nano-patterns by using DNA molecule. In this report it is presented that λ-DNA was aligned on Si substrate by using the free-flowing method and then imaged by an atomic force microscope (AFM). After the second liquid flow, a catenary-like pattern and a crossed network of λ-DNA were formed. In addition, the aligned λ-DNA was successfully cut off by tips of AFM.

Abstract: OBJECTIVE: To investigate the effects of platycodin D in combination with different active ingredients of Chinese herbs under different therapeutic principles on proliferation and invasion of 4T1 and MDA-MB-231 breast cancer cell lines. METHODS: The effective doses of platycodin D, Ophiopogon total saponins, curcumenol and osthole in inhibiting proliferation of breast cancer cell lines 4T1 and MDA-MB-231 were detected by methyl thiazolyl tetrazolium (MTT) assay, respectively. Optimized combinations of platycodin D with Ophiopogon total saponins, curcumenol, or osthole were determined by uniform design method. Effects of the optimized combinations of platycodin D with the three ingredients on proliferation and invasion of 4T1 and MDA-MB-231 cells were verified and evaluated by MTT assay and Transwell chamber test, respectively. RESULTS: Verifying study showed that the inhibitory effects of platycodin D in combination with curcumenol or osthole on proliferation of 4T1 and MDA-MB-231 cells were better than those of platycodin D in combination with Ophiopogon total saponins and each ingredient used alone (P<0.05 or P<0.01). The inhibitory effect of platycodin D in combination with Ophiopogon total saponins or osthole on invasion of 4T1 cells was significantly better than those of platycodin D in combination with curcumenol and each ingredient used alone (P<0.05 or P<0.01). Moreover, the inhibitory effect of platycodin D in combination with curcumenol or osthole on invasion of MDA-MB-231 cells was significantly better than that of platycodin D in combination with Ophiopogon total saponins (P<0.01).CONCLUSION: The optimized combinations of platycodin D with three different active ingredients of Chinese herbs under different therapeutic principles can significantly inhibit the proliferation and decrease the invasion of 4T1 and MDA-MB-231 cells. Different platycodin D combinations have different potency in suppressing breast cancer cell proliferation and invasion.
Niche Construction on Environmental Gradients: The Formation of Fitness Valley and Stratified Genotypic Distributions
Xiaozhuo Han, Cang Hui
PLOS ONE , 2014, DOI: 10.1371/journal.pone.0099775
Abstract: The process of niche construction can alter the trajectory of natural selection through organism-environment feedback. As such, the mechanism and impact of niche construction can be better investigated along environmental gradients. Here we investigate how the process of niche construction affects the distribution of genotypes and fitness landscape along an environmental gradient under three selection regimes, namely heterozygote superiority, genetic loci which dictates niche construction ability being either selectively neutral or non-neutral. Using a spatially explicit cellular automaton, we show that niche construction can stratify genetic diversity by forming band-like distributions consisting of different genotypic compositions and promote reproduction isolation by forming a divide with reduced average fitness along the gradients, termed a fitness valley. The band structure and the presence of a fitness valley depend on heterogeneous environments, resource-dependent fitness and the selection acting on the gene loci affecting the niche-constructing ability. Our work adds to the growing body of evidence on criticizing species distribution models which assume that the environment alone can determine species distributions. Based on the results, we argue that conservation planning should target preserving or restoring environmental gradients.
Fourier-transform Ghost Imaging for pure phase object based on Compressive Sampling algorithm
Hui Wang,Shensheng Han
Physics , 2009,
Abstract: A special algorithm for the Fourier-transform Ghost Imaging (GI) scheme is discussed based on the Compressive Sampling (CS) theory. Though developed mostly in real space, CS algorithm could also be used for the Fourier spectrum reconstruction of pure phase object by setting a proper sensing matrix. This could find its application in diffraction imaging of X-ray, neutron and electron with higher efficiency and resolution. Simulation and experiment results are also presented to prove the feasibility.

Five Phases Music Therapy (FPMT) in Chinese Medicine: Fundamentals and Application  [PDF]
Hui Zhang, Han Lai
Open Access Library Journal (OALib Journal) , 2017, DOI: 10.4236/oalib.1104190
Abstract:
Music therapy has served as complementary and alternative medicine for various neurological disorders. Five Phases Music Therapy (FPMT) employs the theory of five phases and five music scales or tones (宫Gong (do), 商Shang (ri), 角Jue (mi), 徵Zhi (so) and 羽Yu (la)) to analyze and treat mind-body illness. In Chinese Medicine (CM), the five music scales are used to connect the human body and the universe, interpret personalities and constitution and analyze the influences of climatic changes on health. FPMT has a self-contained theory and routine of practice application. Large amounts of clinical and fundamental reports have been available and clinical benefits have been obtained. However, more systemic clinic research esp. evidence-based and random controlled trials must be performed to validate and optimize its routines and biological and neurological mechanism must be further explored. It’s reasonable to believe that the effective music therapy will attract more attention from the world outside China with the introduction of FPMT.
Extreme climate events over northern China during the last 50 years

HAN Hui,GONG Daoyi,

地理学报 , 2003,
Abstract: Climate extremes for agriculture-pasture transitional zone, northern China, are analyzed on the basis of daily mean temperature and precipitation observations for 31 stations in the period 1956-2001. Analysis season for precipitation is May-September, i.e., the rainy season. For temperature is the hottest three months, i.e., June through August. Heavy rain events, defined as those with daily precipitation equal to or larger than 50 mm, show no significant secular trend. A jump-like change, however, is found occurring in about 1980. For the period 1980-1993, the frequency of heavy rain events is significantly lower than the previous periods. Simultaneously, the occurring time of heavy rains expanded, commencing about one month early and ending one month later. Long dry spells are defined as those with longer than 10 days without rainfall. The frequency of long dry spells displays a significant (at the 99% confidence level) trend at the value of +8.3%/10a. That may be one of the major causes of the frequent droughts emerging over northern China during the last decades. Extremely hot and low temperature events are defined as the uppermost 10% daily temperatures and the lowest 10% daily temperatures, respectively. There is a weak and non-significant upward trend in frequency of extremely high temperatures from the 1950s to the mid-1990s. But the number of hot events increases as much as twice since 1997. That coincides well with the sudden rise in mean summer temperature for the same period. Contrary to that, the frequency of low temperature events have been decreasing steadily since the 1950s, with a significant linear trend of -15%/10a.
