A Review of Western and Traditional Chinese Medical Approaches to Managing Nonalcoholic Fatty Liver Disease
Nonalcoholic fatty liver disease (NAFLD) is a disease of attention because of increase in prevalence from 20% to 41%. The clinical and pathological conditions in patients with NAFLD range from steatosis alone to nonalcoholic steatohepatitis (NASH) with or without fibrosis to hepatic cancer. In the United States, NAFLD was the second-leading indication for liver transplant between 2004 and 2013. Although imaging studies such as magnetic resonance elastography and the use of diagnostic panels and scoring systems can provide a fairly accurate diagnosis of NAFLD, there are few treatment options for patients with mild to moderate disease other than lifestyle modification. Many of the currently used medical treatments have been shown to cause severe side effects and some have been shown to be associated with increased risk for certain types of cancer. In recent years, a number of traditional Chinese herbal treatments have been examined for their potential uses as treatment for NAFLD. In this review, we provide a general overview of NAFLD and a survey of Western pharmacologic drugs currently used to treat the disease as well as the results of recent studies on the effectiveness of traditional Chinese herbal remedies for managing nonalcoholic fatty liver disease
Modeling the pulse signal by wave-shape function and analyzing by synchrosqueezing transform
We apply the recently developed adaptive non-harmonic model based on the
wave-shape function, as well as the time-frequency analysis tool called
synchrosqueezing transform (SST) to model and analyze oscillatory physiological
signals. To demonstrate how the model and algorithm work, we apply them to
study the pulse wave signal. By extracting features called the spectral pulse
signature, {and} based on functional regression, we characterize the
hemodynamics from the radial pulse wave signals recorded by the
sphygmomanometer. Analysis results suggest the potential of the proposed signal
processing approach to extract health-related hemodynamics features
Chinese Herbal Medicine as an Adjunctive Therapy Ameliorated the Incidence of Chronic Hepatitis in Patients with Breast Cancer: A Nationwide Population-Based Cohort Study
We conducted a National Health Insurance Research Database-based Taiwanese nationwide population-based cohort study to evaluate whether Chinese herbal medicine (CHM) treatment decreased the incidence of chronic hepatitis in breast cancer patients receiving chemotherapy and/or radiotherapy. A total of 81171 patients were diagnosed with breast cancer within the defined study period. After randomly equal matching, data from 13856 patients were analyzed. Hazard ratios of incidence rate of chronic hepatitis were used to determine the influence and therapeutic potential of CHM in patients with breast cancer. The patients with breast cancer receiving CHM treatment exhibited a significantly decreased incidence rate of chronic hepatitis even across the stratification of age, CCI score, and treatments. The cumulative incidence of chronic hepatitis for a period of seven years after initial breast cancer diagnosis was also reduced in the patients receiving CHM treatment. The ten most commonly used single herbs and formulas were effective in protecting liver function in patients with breast cancer, where Hedyotis diffusa and Jia-Wei-Xiao-Yao-San were the most commonly used herbal agents. In conclusion, our study provided information that western medicine therapy combined with CHM as an adjuvant modality may have a significant impact on liver protection in patients with breast cancer
TONGUE DIAGNOSIS OF TRADITIONAL CHINESE MEDICINE FOR RHEUMATOID ARTHRITIS
Rheumatoid arthritis (RA) is a chronic, systemic autoimmune disease with unknown etiology that causes the immune system to attack the joints (synoviums), causing chronic inflammation. According to the traditional Chinese medicine (TCM), RA falls into the category of Impediment disease (「Bi」 syndrome), i.e., poor circulation of qi and blood (stasis). Tongue diagnosis is an important method of TCM to detect blood stasis.
In this study, 74 RA patients, meeting the pre-set criteria, were recruited via rheumatology outpatient clinic and examined by experienced rheumatologist physicians. Two images-one of the tongue and the other, sublingual vessels-of the same patient were taken by a Canon digital camera in a darkroom with uniform lighting conditions. Relevant features of the tongue were extracted by utilizing image processing techniques. Every tongue was classified into corresponding patterns based on the features identified.
The subjects included 62 females and 12 males with an average age of 49.86±13.81 years old, an average morbidity period of 4.56±3.92 years, an average rheumatoid factor(RF) of 225.3±373.8 IU/mL and an average erythrocyte sedimentation rate of (ESR) 40.9±31.9m/hr. According to our study, 86% of the patients with RA have tongues with sublingual vessels with a width of more than 2.7mm, a length of more than 3/5 from tongue tipto sublingual caruncle , or a count of sublingual vessels more than 2. Moreover, since RA index is highly correlated with blood stasis in TCM, a logistic regression is conducted to predict the probability of presence of RA using RF and ESR as explanatory variables. Also, the logistic regression analysis of RA with respect to the conventional tongue diagnosis criteria was performed. Based on the aforementioned studies, we concluded that tongue diagnosis is helpful in detecting blood stasis of RA
An Evaluation of the Additive Effect of Natural Herbal Medicine on SARS or SARS-like Infectious Diseases in 2003: A Randomized, Double-blind, and Controlled Pilot Study
Natural herbal medicine (NHM) has been used to control infectious diseases for thousands of years. In view of the possible beneficial effect of NHM on SARS, we conducted this study to examine whether NHM is of any benefit as a supplementary treatment of SARS or SARS-like infectious disease. This was a randomized, double-blind, placebo-controlled trial. Twenty-eight patients fulfilled the WHO inclusion criteria and our exclusion criteria. All enrolled patients received routine western-medicine treatment. Patients were randomly allocated to one of the three supplementary treatment groups: NHM A (Group A, n = 9) NHM B (Group B, n = 9) or placebo (Group C, n = 10). Chest X-ray was done every 1 or 2 days for every patient. Reading radiologists use a standard 0–3 scoring system (0: no infiltration; 1: focal haziness or even small patchy lesion; 2: ground glass picture; 3: lobar consolidation) according to the severity of infiltration in each lung field (three lung fields in both right and left lungs). The main outcome measurements were the improving chest radiographic scores (IRS) and the duration (days) till improvement (DI). One patient from the placebo group passed away. Patients from NHM A took less days before showing improvement (6.7 ± 1.8) compared with placebo group (11.2 ± 4.9), which showed statistical significance (P = 0.04). The cases were too few to be conclusive, the initial observations seem to indicate NHM appears to be safe in non-criticallly ill patients and clinical trials are feasible in the setting of pandemic outbreaks
Characteristics of Traditional Chinese Medicine Use in Pediatric Dislocations, Sprains and Strains
Background and Objectives: Dislocations, sprains and strains are common childhood musculoskeletal injuries, requiring medical attention. We investigated the characteristics associated with using traditional Chinese medicine (TCM) for children suffering from these injuries. Methods: From a nationwide representative insurance database of Taiwan, this cross-sectional study identified 50,769 children with dislocations, sprains and strains under 18 years of age, newly diagnosed between 1999 and 2009, without previous TCM experience. Children who initiated treatment with TCM (n = 24,063, 47.4%) were defined as TCM users, others were in the non-TCM group. Multivariable logistic regression models estimated odds ratios (ORs) of TCM use. Results: Girls and children living in central Taiwan (vs. northern) were associated with higher TCM use. The adjusted ORs (95% confidence interval (CI)) of TCM uses were 1.60 (1.42–1.79) for patients of 3–5 years, 2.20 (1.99–2.42) of 6–12 years and 1.82 (1.64–2.01) of 13–17 years, compared with those of the <2 years group. TCM users were less likely to have outpatient visits for Western medicine care and hospitalizations in the previous year. The TCM group was nearly twice more likely than the non-user group to receive treatments at local clinics (99.1% vs. 53.3%, p < 0.001). Conclusions: This study reveals important demographic and medical factors associated with TCM uses for children with dislocations, sprains and strains. Interestingly, local clinics are the main healthcare facilities providing TCM services. Further studies are needed to evaluate the outcomes of TCM treatment for these musculoskeletal injuries
On the qi deficiency in traditional Chinese medicine
[[abstract]]Objective
Qi deficiency (QD), one of the most common disorders in Traditional Chinese medicine (TCM), is relevant to many disorders in obstetrics and gynecology. This study aimed to identify the common processes and criteria for diagnosing QD among contemporary proficient TCM practitioners.
Materials and methods
Steps of decision tree analysis and modified Delphi method were merged together into four-round postal questionnaires to collect qualitative and quantitative data. Open-ended questions and content analysis were used to explore the proficient TCM practitioners' cognitive activities used for diagnosis. The statements obtained from the qualitative responses were used to develop the items for subsequent questionnaires. Based on the TCM practitioners' responses, the diagnostic processes and criteria for making diagnosis were generated.
Results
Twenty-eight out of the 30 participants completed all four questionnaires from June 2007 to January 2010. The 11 diagnostic procedures identified in the returned first round of questionnaires were used as the alternatives to select and rank for all the steps to diagnose QD. After three more rounds of postal surveys, an algorithm with a five-stage diagnostic process as well as sets of decision criteria were identified. Although the priorities of procedures and descriptions of reasoning were varied, the content revealed the major themes in the model. The criteria to differentiate signs and symptoms (S/S) included five principles for correlating S/S with QD, and 17 S/S should be differentiated carefully.
Conclusion
The results demonstrate that the TCM practitioners precisely diagnosed QD using a number of specific procedures and criteria that could be used as a reference to understand women complaining of S/S that could be similar to QD

Hepatoprotective effects of Ger-Gen-Chyn-Lian-Tang in thioacetamide-induced fibrosis in mice
Background: Many researchers have focused on developing traditional herbal medicines as pharmacological medicines to treat hepatic fibrosis. In this study, we evaluated the possible mechanism of Ger-Gen-Chyn-Lian-Tang (GGCLT) on thioacetamide (TAA)-induced hepatic injury in mice.
Methods: Hepatic fibrosis mice were established by intraperitoneal injection with TAA (100 mg/kg, 3 times/week), and treated with daily oral administration of 30 mg/kg, 100 mg/kg, and 300 mg/kg of GGCLT for 6 weeks. There were 40 mice randomly assigned to control, TAA and TAA+GGCLT groups. When the experiment was completed, Masson's trichrome staining was used to measure the degree of liver fibrosis. Hepatic fibrosis molecules were assessed by Western blot and real-time polymerase chain reaction. Hepatic glutathione levels, matrix metalloproteinase (MMP-2 and MMP-9), and hydroxyproline were also measured.
Results: Treatment with GGCLT significantly reduced the toxicity of TAA and exhibited effective hepatoprotective activity. The mechanism of the hepatoprotective effect of GGCLT is proposed to be by normalizing oxidative stress. Additionally, the data of fibrotic areas, expression of procollagen III, and MMP2 and 9 mRNA levels in the TAA+GGCLT group were much lower than those in the TAA group (p < 0.05). Furthermore, the upregulation of hepatic protein levels of nuclear factor-κB, transforming growth factor (TGF)-β receptor-1, and smooth muscle α-actin induced by TAA was significantly inhibited after GGCLT treatment.
Conclusion: GGCLT can efficiently ameliorate hepatic fibrosis by its inhibitory effects on the intrahepatic oxidative stress in TAA mice model. The antioxidant properties afforded by GGCLT may be attributed to its modulation on TGF-β/TGFβ receptor signaling through the downregulation of integrated signal pathways involving smooth muscle α-actin and lipid peroxidation
Effect of the Chinese Herbal Medicine SS-1 on a Sjögren’s Syndrome-Like Disease in Mice
Sjögren’s syndrome (SS) is an inflammatory autoimmune disease primarily affecting the exocrine glands; it has a major impact on patients’ lives. The Chinese herbal formula SS-1 is composed of Gan Lu Yin, Sang Ju Yin, and Xuefu Zhuyu decoction, which exerts anti-inflammatory, immunomodulatory, and antifibrotic effects. Our previous study demonstrated that SS-1 alleviates clinical SS. This study aimed to evaluate the efficacy and mechanism of the Chinese herbal formula SS-1 for salivary gland protein-induced experimental Sjögren’s syndrome (ESS). These results showed that ESS treatment with the Chinese herbal formula SS-1 (1500 mg/kg) significantly alleviated the severity of ESS. We found that SS-1 substantially improved saliva flow rates in SS mice and ameliorated lymphocytic infiltrations in submandibular glands. In addition, salivary gland protein-induced SS in mice treated with SS-1 significantly lowered proinflammatory cytokines (including IFN-γ, IL-6, and IL-17A) in mouse salivary glands and decreased serum anti-M3R autoantibody levels. In addition, we found that CD4+ T cells isolated from SS-1-treated SS mice significantly reduced the percentages of IFN-γ-producing CD4+ T cells (Th1) and IL-17A-producing CD4+ T cells (Th17). Our data show that SS-1 alleviates ESS through anti-inflammatory and immunomodulatory effects, which provides new insight into the clinical treatment of SS
