Adjunctive Chinese Herbal Medicine Treatment is Associated With an Improved Survival Rate in Patients With Cervical Cancer in Taiwan: A Matched Cohort Study.

BACKGROUND: Cervical cancer is one of the most common cancers in Taiwan. Some patients take Chinese herbal medicine (CHM). However, very few current studies have ascertained the usage and efficacy of CHM in patients with cervical cancer. The aim of this study was to investigate the benefits of complementary CHM among patients with cervical cancer in Taiwan. METHODS: We included the newly diagnosed cervical cancer patients who were registered in the Taiwanese Registry for Catastrophic Illness Patients Database between 2000 and 2010. The end of follow-up period was December 31, 2011. Patients who were less than 20 years old, had missing information for age, withdrew from the National Health Insurance (NHI) program during the follow-up period, or only received other TCM interventions such as acupuncture or tuina massage were excluded from our study. After performing 1:1 frequency matching by age and index date, we enrolled 7521 patients in both CHM and non-CHM user groups. A Cox regression model was used to compare the hazard ratios (HRs) of the risk of mortality. The Kaplan-Meier curve was used to compare the difference in survival time. RESULTS: According to the Cox hazard ratio model mutually adjusted for CHM use, age, comorbidity, treatment, and chemotherapeutic agents used, we found that CHM users had a lower hazard ratio of mortality risk (adjusted HR = 0.29, 95%CI = 0.27-0.31). The survival probability was higher for patients in the CHM group. Bai-Hua-She-She-Cao (Herba Oldenlandiae, synonym Herba Hedyotis diffusae) and Jia-Wei-Xiao-Yao-San were the most commonly prescribed single herb and Chinese herbal formula, respectively. CONCLUSIONS: Adjunctive CHM may have positive effects of reducing mortality rate and improving the survival probability for cervical cancer patients. Further evidence-based pharmacological investigations and clinical trials are warranted to confirm the findings in our study.

Coprescription Trends in Western Medicine, Chinese Herbal Medicine and Dental Medicine among Older Adults in Taiwan from 1997 to 2013.

BACKGROUND: Coprescription is a potential medical problem for older adults that could induce polypharmacy and subsequent complications. In Taiwan, Chinese herbal medicine (CHM) is popular among the older adults. Investigating the coprescription trends in Western medicine, CHM and dental medicine is important to avoid possible polypharmacy. METHODS: We analyzed data from the Longitudinal Health Insurance Database 2000 (LHID 2000) in Taiwan. Patients ≥ 60 years old who received coprescription of Western medicine, CHM and drugs for dental care from 1997 to 2013 were included. The odds ratio (OR) and 95% confidence interval (95% CI) were estimated by a logistic regression model for evaluating the correlation between baseline characteristics and coprescription. RESULTS: A total of 266,034 patients were included for the analysis. Most patients receiving coprescriptions lived in the northern Taiwan and with a monthly income lower than 20,000 new Taiwan dollars. The trends in older adults using Western medicine alone or CHM alone decreased over time, but the cohort using dental medicine alone had the opposite result. Decreased trends in coprescription with age were noted. The trends in the proportion of coprescription and the number of days of coprescription increased with the calendar year. Increased trends in the proportion of patients with coprescription were also found, except for the cohort of patients who used both Western medicine and CHM. Patients who were female, and aged 70-79 years were prone to receive coprescription. CONCLUSIONS: Coprescription in older patients is not uncommon in Taiwan. Healthcare providers and policymakers should be aware of the complex coprescription pattern in the older adults.

Acupuncture Treatment Reduced the Risk of Coronary Heart Disease in Patients with Depression: A Propensity-Score Matched Cohort Study.

BACKGROUND: Major depressive disorder is a significant public health concern, which often leads to loss of productivity, functional decline, and various complications. The aim of this study was to investigate the effectiveness of acupuncture in the risk reduction of coronary heart disease (CHD) in patients with depression. METHODS: We enrolled patients diagnosed with depression between January 1, 1997, and December 31, 2010, through the Taiwanese National Health Insurance Research Database (NHIRD). Propensity score was used to match equal numbers (n=14,647) of acupuncture cohort and no-acupuncture cohort based on characteristics including sex, age, baseline comorbidity and medication. Patients were followed up until December 31, 2013, or withdrawn from the NHIRD. The Cox regression model was used to compare the hazard ratios (HRs) of CHD in the two cohorts. RESULTS: The basic characteristics of the two groups were similar. A lower cumulative incidence of CHD was noted in the acupuncture cohort (Log rank test, p < 0.001). Over time, 1626 patients in the acupuncture cohort (21.05 per 1000 person-years) and 2412 patients in the no-acupuncture cohort (39.84 per 1000 person-years) developed CHD (adjusted HR=0.50, 95% CI 0.47-0.53). The decreased CHD incidence was independent of age, sex, comorbidities, and medications used. The cumulative incidence of CHD was significantly lower in the acupuncture cohort than in the no-acupuncture cohort (Log rank test, p<0.001). CONCLUSION: The results provided a real-world evidence that acupuncture may have beneficial effect on CHD risk reduction in patients with depression.

Association between oophorectomy and depression in patients with comorbidities: A nationwide cohort study in Taiwan.

OBJECTIVE: This study investigated the long-term rates of depression after oophorectomy for benign gynecological conditions with or without comorbidities. MATERIALS AND METHODS: This retrospective cohort study examined data from the National Health Insurance Research Database (NHIRD) involving 8199 women aged ≥20 years who underwent unilateral or bilateral oophorectomy for benign gynecological conditions (cases) between 2000 and 2013 (index date). A second cohort consisted of 32,796 women who did not undergo oophorectomy (controls) who were matched 4:1 to cases by age and index year. The follow-up time was more than 10 years. For all participants, the analysis accounted for comorbidities including hypertension, diabetes mellitus, hyperlipidemia, stroke, chronic obstructive pulmonary disease (COPD), chronic liver disease and cirrhosis, chronic kidney disease, and anxiety. Crude hazard ratios, adjusted hazard ratios, and 95% confidence intervals (CIs) were calculated according to multivariable Cox proportional hazard regression models adjusting for age, comorbidity, and the combination of oophorectomy with one comorbidity. RESULTS: Our results show that unilateral or bilateral oophorectomy, whether performed by laparotomy or laparoscopy, increases the overall risk of depression (aHR: 1.36, 95%CI: 1.19-1.55). Compared with controls, women aged <50 years had a significantly higher incidence of depression. Having diabetes (aHR: 1.66, 95%CI: 1.09-2.51), hypertension (aHR:1.56, 95%CI:1.14-2.14), hyperlipidemia (aHR: 1.46, 95%CI: 1.04-2.05), stroke (aHR: 1.91, 95%CI: 1.01-3.60), COPD (aHR: 2.06, 95%CI: 1.3-3.26), chronic liver cirrhosis (aHR: 1.99, 95%CI:1.52-2.61), or anxiety (aHR: 5.01, 95%CI: 3.74-6.70) increased higher risk of depression compared with not having these comorbidities after oophorectomy. The likelihood of depression was highest within the first 6 years following oophorectomy (3-5years:aHR:1.26, 95%CI:1.00-1.58). CONCLUSIONS: Oopherectomy increases the overall risk of depression. We offer useful information for surgical decision-making and preoperative assessments of women undergoing oophorectomy. It is concluded that a synergistic effect exists between oophorectomy and the comorbidities. Post-surgery, physicians should carefully evaluate the risk of depression developing amongst women with comorbidities. A postoperative follow-up time of at least 6 years is recommended, as this period was associated with a significantly higher rate of depression during our over 10-year follow-up.

A Potential Herbal Adjuvant Combined With a Peptide-Based Vaccine Acts Against HPV-Related Tumors Through Enhancing Effector and Memory T-Cell Immune Responses.

Viral infection is associated with many types of tumorigenesis, including human papillomavirus (HPV)-induced cervical cancer. The induction of a specific T-cell response against virus-infected cells is desired to develop an efficient therapeutic approach for virus-associated cancer. Chinese herbal medicine (CHM) has a long history in the treatment of cancer patients in Asian countries. Hedyotis diffusa Willd (Bai Hua She She Cao, BHSSC) is frequently used clinically and has been shown to inhibit tumor growth in vitro. However, in vivo data demonstrating the antitumor efficacy of BHSSC are still lacking. We showed that BHSSC induces murine and human antigen-presenting cell (APC) activation via the MAPK signaling pathway and enhances antigen presentation in bone marrow-derived dendritic cells (BMDCs) in vitro. Furthermore, we identified that treatment with BHSSC leads to improved specific effector and memory T-cell responses in vivo. Variant peptide-based vaccines combined with BHSSC improved antitumor activity in preventive, therapeutic, and recurrent HPV-related tumor models. Furthermore, we showed that rutin, one of the ingredients in BHSSC, induces a strong specific immune response against HPV-related tumors in vivo. In summary, we demonstrated that BHSSC extract and its active compound, rutin, can be used as adjuvants in peptide-based vaccines to increase immunogenicity and to bypass the requirement of a conditional adjuvant.

Cold-water extracts of Grifola frondosa and its purified active fraction inhibit hepatocellular carcinoma in vitro and in vivo.

Mushrooms are used in traditional Chinese medicine to treat a variety of diseases. Grifola frondosa (GF) is an edible mushroom indigenous to many Asian countries with a large fruiting body characterized by overlapping caps. In particular, GF is known for its anti-tumor activity, which has been targeted by scientific and clinical research. This study aimed to investigate the effects of the cold-water extract of GF (GFW) and its active fraction (GFW-GF) on autophagy and apoptosis, and the underlying mechanisms in vitro and in vivo Our results revealed that GFW and GFW-GF inhibited phosphatidylinositol 3-kinase (PI3K) and stimulated c-Jun N-terminal kinase (JNK) pathways, thereby inducing autophagy. We also demonstrated that GFW and GFW-GF inhibited proliferation, induced cell cycle arrest, and apoptosis in Hep3B hepatoma cells. GFW and GFW-GF markedly arrested cells in S phase and promoted cleavage of caspase-3 and -9. In addition, GFW and GFW-GF decreased the expression levels of the anti-apoptotic proteins protein kinase B and extracellular signal-regulated kinase. We also found that GFW significantly inhibited tumor growth in nude mice implanted with Hep3B cells. Our work demonstrates that GF and its active fraction inhibit hepatoma growth by inducing autophagy and apoptosis.

Protective effect of Flos carthami extract against ethylene glycol-induced urolithiasis in rats.

Flos carthami (FC), also known as Carthamus tinctorius, is a traditional Chinese herbal plant that has been prescribed since centuries for treating various symptoms related to blood circulation improvement. This study aimed to investigate the effects of FC on calcium oxalate (CaOx) formation in ethylene glycol (EG)-fed rats. A total of 50 male Sprague-Dawley rats were divided into the following 6 groups: group 1, as the normal control (n = 5); group 2 received gastric gavages of starch and 0.75% EG (placebo, n = 5) as a stone inducer; group 3 (n = 10) received EG and potassium citrate as positive controls; group 4 (n = 10) received 0.75% EG and 300 mg/day FC; group 5 (n = 10) was treated with EG and 600 mg/day FC; group 6 (n = 10) received with EG and 1,200 mg/day FC. For all experimental animals, 24-h urine and blood samples were analyzed at the beginning and end of the experiment. Kidney tissue was histopathologically examined using a polarized light microscope, and crystal deposits were evaluated by a semi-quantitative scoring method; these scores were significantly lower in the FC groups (600 and 1,200 mg/day) than in the placebo group. Thus, FC administration appeared to inhibit the deposition of CaOx crystal EG-fed rats. We, therefore, consider that FC may be effective for preventing stone disease, albeit with certain side effects, such as a bleeding tendency. Further clinical trials are needed for evaluating its benefits and possible side effects.

Application of skin electrical conductance of acupuncture meridians for ureteral calculus: a case report.

Renal colic is a common condition seen in the emergency department (ED). Our recent study showed that measures of electrical conductance may be used as supplementary diagnostic methods for patients with acute renal colic. Here, we describe the case of a 30-year-old male subject with a left ureteral calculus who presented with frequency and normal-looking urine. He had already visited the outpatient department, but in vain. Normal urinalysis and nonobstructive urogram were reported at that time. Two days later, he was admitted to the ED because of abdominal pain in the left lower quadrant. The urinalysis did not detect red blood cells. Ultrasonography did not indicate hydronephrosis. The meridian electrical conductance and index of sympathovagal balance were found to be abnormal. High level of electrical conductance on the left bladder meridian was found. An unenhanced helical computed tomography was scheduled to reveal a left ureterovesical stone. Ureteroscopic intervention was later uneventfully performed, and the patient's pain was relieved. The follow-up measurements showed that the meridian parameters had returned to normal one month after treatment. This case suggests that bladder meridian electrical conductance might be used as a supplemental method for ureteral calculus diagnosis.
