Effectiveness of Chinese herbal medicine compared with angiotensin II receptor blockers in patients with diabetic kidney disease: A hospital-based matched cohort study.

Angiotensin II receptor blockers (ARBs) are one of the standard treatments for diabetic kidney disease (DKD). Some patients may opt for Chinese herbal medicine (CHM) of their own free will. However, there is no real-world evidence regarding the effectiveness and safety of CHM. We aimed to explore the effectiveness of CHM for DKD in comparison to ARBs. We enrolled 732 DKD patients (72 used only CHM and 661 used ARBs) from 2007 to 2016, and all patients were followed until December 2016 at China Medical University Hospital in Taiwan. A total of 355 ARB users and 71 CHM users were analyzed after propensity score matching. The estimated glomerular filtration rate (eGFR) after treatment was 84.9 ± 28.1 ml/min/1.73 m2 in CHM users, which was higher than that (67.8 ± 35.4 ml/min/1.73 m2) in ARB users (p < 0.001). The change in the eGFR was -6.0 ± 21.4 ml/min/1.73 m2 in CHM users and -12.9 ± 24.8 ml/min/1.73 m2 in ARB users (p = 0.029). The blood urea nitrogen (BUN) and creatinine levels of patients taking CHM were 22 ± 16 mg/dl and 0.9 ± 0.4 mg/dl, respectively, and were lower than those (30 ± 28 mg/dl and 1.7 ± 2.0 mg/dl) of patients taking ARBs (p = 0.025 and p = 0.003). Using linear regression with adjustments for age, sex, BMI, baseline eGFR, and HbA1c levels, we found that the declines in the eGFR/baseline eGFR and changes in the urine albumin-creatinine ratio (ACR) were comparable between the two groups (p = 0.86 and 0.73). This study suggests that CHM may have comparable effectiveness to ARBs, which provides insights for further investigations.

Identification of Fangchinoline as a novel autophagy inhibitor with an adjuvant of chemotherapy against lung cancer.

Autophagy is a fundamental recycling pathway that enhances cellular resilience, promoting survival. However, this survival mechanism can impede anti-cancer treatment strategies designed to induce cell death. In this study, we identified a novel autophagy inhibitor, Fangchinoline (Fan) isolated from the traditional Chinese medicine Stephania tetrandra. We speculated that when Fan blocks autophagy, cancer cells lose substantial self-preservation abilities during treatment. Firstly, we examined in detail the mechanism through which Fan inhibits autophagy. Specifically, Fan induced a significant increase in autophagosomes, as indicated by GFP-LC3 labeling, confirmed by the up-regulation of LC3-II. The autophagy receptor protein p62 was also up-regulated, suggesting a potential inhibition of autophagy flux. We further ruled out the possibility of fusion barriers between lysosomes and autophagosomes, as confirmed by their co-localization in double fluorescence staining. However, the lysosomal acid environment might be compromised, as suggested by the diminished fluorescence of acidity-sensitive dyes in the lysosomes and the corresponding decrease in mature forms of lysosomal cathepsin. To test the anti-cancer potential of Fan, we combined it with Cisplatin (Cis) or Paclitaxel (PTX) for lung cancer cell treatment. This combined treatment demonstrated a synergistically enhanced killing effect. These promising anti-tumor results were also replicated in a xenografted tumor model. The significance of this research lies in the identification of Fan as a potent autophagy inhibitor and its potential to enhance the efficacy of existing anti-cancer drugs. By unraveling the mechanisms of Fan's action on autophagy and demonstrating its synergistic effect in combination therapies, our study provides valuable insights for developing novel strategies to overcome autophagy-mediated resistance in cancer treatment.

Identification of Fangjihuangqi Decoction as a late-stage autophagy inhibitor with an adjuvant anti-tumor effect against non-small cell lung cancer.

BACKGROUND: Clinically, although chemotherapy is one of the most commonly used methods of treating tumors, chemotherapeutic drugs can induce autophagic flux and increase tumor cell resistance, leading to drug tolerance. Therefore, theoretically, inhibiting autophagy may improve the efficacy of chemotherapy. The discovery of autophagy regulators and their potential application as adjuvant anti-cancer drugs is of substantial importance. In this study, we clarified that Fangjihuangqi Decoction (FJHQ, traditional Chinese medicine) is an autophagy inhibitor, which can synergistically enhance the effect of cisplatin and paclitaxel on non-small cell lung cancer (NSCLC) cells. METHODS: We observed the changes of autophagy level in NSCLC cells under the effect of FJHQ, and verified the level of the autophagy marker protein and cathepsin. Apoptosis was detected after the combination of FJHQ with cisplatin or paclitaxel, and NAC (ROS scavenger) was further used to verify the activation of ROS-MAPK pathway by FJHQ. RESULTS: We observed that FJHQ induced autophagosomes in NSCLC cells and increased the levels of P62 and LC3-II protein expression in a concentration- and time-gradient-dependent manner, indicating that autophagic flux was inhibited. Co-localization experiments further showed that while FJHQ did not inhibit autophagosome and lysosome fusion, it affected the maturation of cathepsin and thus inhibited the autophagic pathway. Finally, we found that the combination of FJHQ with cisplatin or paclitaxel increased the apoptosis rate of NSCLC cells, due to increased ROS accumulation and further activation of the ROS-MAPK pathway. This synergistic effect could be reversed by NAC. CONCLUSION: Collectively, these results demonstrate that FJHQ is a novel late-stage autophagy inhibitor that can amplify the anti-tumor effect of cisplatin and paclitaxel against NSCLC cells.

A Novel Strategy for Screening Active Components in Cistanche tubulosa Based on Spectrum-Effect Relationship Analysis and Network Pharmacology.

Cistanche tubulosa (Schenk) R. Wight is a valuable herbal medicine in China. The study aimed to explore the potential mechanisms of C. tubulosa on antioxidant activity using spectrum-effect relationship and network pharmacology and the possibilities of utilizing herbal dregs. In this work, different extracts of C. tubulosa, including herbal materials, water extracts, and herbal residues, were evaluated using high-performance liquid chromatography (HPLC) technology. In addition, the antioxidant activities were estimated in vitro, including 2, 2-diphenyl-1-picrylhydrazyl; superoxide anion; and hydroxyl radical scavenging assays. The spectrum-effect relationships between the HPLC fingerprints and the biological capabilities were analyzed via partial least squares regression, bivariate correlation analysis, and redundancy analysis. Furthermore, network pharmacology was used to predict potential mechanisms of C. tubulosa in the treatment of antioxidant-related diseases. According to the results, eleven common peaks were shared by different extracts. Geniposidic acid, echinacoside, verbascoside, tubuloside A, and isoacteoside were quantified and compared among different forms of C. tubulosa. The spectrum-effect relationship study indicated that peak A 6 might be the most decisive component among the three forms. Based on network pharmacology, there were 159 target genes shared by active components and antioxidant-related diseases. Targets related to antioxidant activity and relevant pathways were discussed. Our results provide a theoretical basis for recycling the herbal residues and the potential mechanisms of C. tubulosa in the treatment of antioxidant-related diseases.

Integrated Chinese herbal medicine and Western medicine successfully resolves spontaneous subcutaneous emphysema and pneumomediastinum in a patient with severe COVID-19 in Taiwan: A case report.

CASE: Serious complications of severe coronavirus disease 2019 (COVID-19) include subcutaneous emphysema (SE) and pneumomediastinum, which are complicated to treat with conventional Western medicine. We report how combining Chinese herbal medicine (CHM) with Western medicine quickly resolved a patient's COVID-19-associated pulmonary complications, shortened hospital stay and improved quality of life. CLINICAL FEATURES AND OUTCOME: A 59-year-old male with a history of smoking and tumors was diagnosed with COVID-19 in May 2021. At hospitalization, his oxygen saturation (SpO2) was 80%, he had a continuous severe cough, rapid shallow breathing, spontaneous SE and pneumomediastinum. By Day 4 of hospitalization, his condition was worsening despite standard care, so CHM was added. After 3-5 days, his coughing had lessened and supplementary oxygen therapy was de-escalated. Nine days after starting CHM, the SE had completely resolved and the patient avoided intubation. His WHO OS 10-point Scale score had fallen from 6 to 3 points and the modified Medical Research Council Dyspnea Scale score from 4 to 2 points. He was hospitalized for 19 days. At 1 week post-discharge, the patient could handle most of his daily activities and experienced minor shortness of breath only when performing labor-intensive tasks. At 1 month, his work output was restored to pre-COVID-19 levels. CONCLUSION: CHM combined with standard Western medicine improved pulmonary function, respiratory rate, blood oxygen saturation and shortened the hospital stay of a patient with severe COVID-19 complicated by SE and pneumomediastinum.

[Changes in physicochemical property and microbial community of Pseudostellaria heterophylla soil at diffe-rent fallow ages]. / 太子参不同休耕年限土壤理化特征和微生物群落变化.

Pseudostellaria heterophylla is authentic traditional Chinese herbal medicine in Fujian Province. P. hete-rophylla suffers from serious consecutive monoculture problems. Fallow can alleviate such problems, but the mecha-nism is still unclear. In this study, high-throughput sequencing was performed to analyze the changes in soil microbial community structure and diversity in the P. heterophylla soil at different fallow ages as well as their relationships with soil physicochemical properties and phenolic acids. The results showed that fungal community diversity decreased but bacterial community diversity increased in fallow soils compared with the control soil of P. heterophy-lla. For bacterial communities, the relative abundance of Acidobacteria increased, while that of Proteobacteria and Actinobacteria decreased in fallow soils. For fungal communities, the relative abundance of dominant phyla had no significant difference between fallow and control soils. Soil acidity and organic matter content showed a trend of weakening and decreasing, respectively, with the increases of fallow years. In addition, with the increases of fallow years, the content of phenolic acids in soil, including benzoic acid and salicylic acid, showed significant decrease, while some other phenolic acids such as p-coumaric acid were accumulated obviously. Taken together, fallow could efficiently ameliorate the structure of soil microbial community and soil properties of P. heterophylla, and thus alleviate the effects of continuous cropping.

Synchronous N and P Removal in Carbon-Coated Nanoscale Zerovalent Iron Autotrophic Denitrification─The Synergy of the Carbon Shell and P Removal.

Fe0 is a promising electron donor for autotrophic denitrification in the simultaneous removal of nitrate and phosphorus in low C/N wastewater. However, P removal may inevitably inhibit bio-denitrification. It has not been well recognized and led to an overdose of iron materials. This study employed carbon-coated zerovalent iron (Fe0@C) to support autotrophic denitrification to mitigate the inhibition effects of P removal and enhance both N and P removal. The critical role of the carbon shell in Fe0@C was to block the direct contact between Fe0 and P and NO3--N, to maintain the Fe0 activity. Besides, P inhibited the chemical reduction of NO3--N by competing for Fe0 active sites. This indirectly boosted H2 generation and promoted bio-denitrification. P removal displayed negligible effects on microbial species but indirectly enhanced the nitrogen metabolic activities because of promoted H2 in Fe0@C-based autotrophic denitrification. Bio-denitrification, in turn, strengthened Fe-P co-precipitation by promoting the formation of ferric hydroxide as a secondary adsorbent for P removal. This study demonstrated an efficient method for simultaneous N and P removal in autotrophic denitrification and revealed the synergistic interactions among N and P removal processes.

[Effect of electroacupuncture at "Shuigou" (GV26) and "Baihui" (GV20) on autophagy of hippo-campal neurons in rats with cerebral ischemia-reperfusion injury].

OBJECTIVE: To explore the effect of electroacupuncture (EA) at "Shuigou"(GV6) and "Baihui"(GV20) on autophagy of hippocampal neurons in cerebral ischemia-reperfusion (I/R) injury rats. METHODS: Forty-eight healthy male SD rats were randomly divided into sham operation, model and EA groups, with 16 rats in each group. The rat model of cerebral I/R injury was established by occlusion of the middle cerebral artery (MCAO). Rats of the EA group received EA at GV26 and GV20 for 20 min, once daily for 5 days. The neurological function of rats in each group was evaluated by Longa neurological function score. The cerebral infarction volume was measured by TTC staining. The levels of IL-6, IL-18 and TNF-α in cerebrospinal fluid were detected by ELISA. Real-time PCR and Western blot were respectively used to detect the expressions of autophagy-related proteins AMPK, Beclin-1, VPS34 and LC3B. RESULTS: Compared with the sham operation group, neurological function scores of rats in the model group were significantly increased (P<0.01); the volume of cerebral infarction was significantly increased (P<0.01); the contents of IL-6, IL-18 and TNF-α in cerebrospinal fluid were increased (P<0.01, P<0.05); the mRNA expression levels of AMPK, Beclin-1, VPS34 and LC3B were significantly increased (P<0.01); the protein expressions of AMPK, Beclin-1, VPS34 and the ratio of LC3B-Ⅱ/LC3B-Ⅰ were increased (P<0.01, P<0.05). After intervention and in comparison with the model group, the neurological function scores were decreased (P<0.05); the cerebral infarct volume were decreased (P<0.05); the contents of IL-6, IL-18 and TNF-α in cerebrospinal fluid were decreased (P<0.05); the mRNA expressions of AMPK, Beclin-1, VPS34 and LC3B were significantly decreased (P<0.01); the protein expressions of AMPK, Beclin-1, VPS34 and the ratio of LC3B-Ⅱ/LC3B-Ⅰ were decreased (P<0.05, P<0.01). CONCLUSION: EA can improve the neurological function and alleviate the degree of nerve injury in rats with cerebral I/R injury, which may be related to inhibiting the autophagy level of hippocampal neurons.

Longitudinal Effects of a Combined Program of Pelvic Floor Muscle Training and Yoga on Genitourinary Symptoms in Asian Women of Older Age: A Randomized Experimental Study.

This parallel-two-group randomized experimental study including a supervised group and an unsupervised group examined the longitudinal effects of pelvic floor muscle training (PFMT) combined with yoga on genitourinary symptoms and the health-related quality of life (HRQOL), and compared practice adherence rates of the two groups. A sample of women experiencing ≥1 genitourinary symptom(s) were recruited and assigned to a supervised group or an unsupervised group. The supervised group attended supervised group practice sessions and performed at-home practice of PFMT and yoga. The unsupervised group performed at-home practice of PFMT and yoga. Information was collected at five time points (n = 91). Generalized estimating equation procedures were used to examine the intervention effects. An independent t-test was conducted to compare the practice adherence rates. Both groups' genitourinary symptoms and HRQOL significantly improved over time. The supervised group displayed greater improvements in genitourinary symptoms and HRQOL and better adherence than did the unsupervised group.

Effects of Iron Supplementation on Testicular Function and Spermatogenesis of Iron-Deficient Rats.

Iron deficiency is the most common micronutrient deficiency in the world. Previous studies have shown that iron deficiency increases oxidative stress and decreases antioxidant enzymes, and studies of male infertility indicated that oxidative stress may affect male reproductive functions. The aim of this study was to investigate the effects of iron supplementation on spermatogenesis and testicular functions in iron-deficient rats. Three-week-old male Sprague Dawley (SD) rats were randomly divided into two groups: an iron-adequate control (AI group, 35 ppm FeSO4) and an iron-deficient group (ID group, <5 ppm FeSO4). After three weeks, the iron-deficient group was divided into an original iron-deficient group and five iron-supplemented groups, the latter fed diets containing different doses of FeSO4 (6, 12, 18, 24, and 35 ppm). After five weeks, blood and testis tissue were analyzed. We presented as median (interquartile range, IQR) for continuous measurements and compared their differences using the Kruskal−Wallis test followed by the Mann−Whitney U test among groups. The results showed that as compared with the AI group, the ID group had significantly lower serum testosterone and poorer spermatogenesis (The medians (QR) were 187.4 (185.6−190.8) of AI group vs. 87.5 (85.7−90.4) of ID group in serum testosterone, p < 0.05; 9.3 (8.8−10.6) of AI group vs. 4.9 (3.4−5.4) of ID group in mean testicular biopsy score (MTBS], p < 0.05); iron supplementation reversed the impairment of testis tissue. In the testosterone biosynthesis pathway, iron supplementation improved the lowered protein expressions of hydroxysteroid dehydrogenases caused by iron deficiency. Additionally, decreased activities of glutathione peroxidase and catalase, and increased cleaved-caspase 8 and caspase 3 expression, were found in the iron-deficient rats. The iron-supplemented rats that received > 12 ppm FeSO4 exhibited improvements in antioxidant levels. In conclusion, iron supplementation can abrogate testis dysfunction due to iron deficiency through regulation of the testicular antioxidant capacity.

Combined Acupoints for the Treatment of Patients with Obesity: An Association Rule Analysis.

Obesity is a prevalent metabolic disease that increases the risk of other diseases, such as hypertension, diabetes, hyperlipidemia, cardiovascular disease, and certain cancers. A meta-analysis of 11 randomized sham-controlled trials indicates that acupuncture had adjuvant benefits in improving simple obesity, and previous studies have reported that acupoint combinations were more useful than single-acupoint therapy. The Apriori algorithm, a data mining-based analysis that finds potential correlations in datasets, is broadly applied in medicine and business. This study, based on the Apriori algorithm-based association rule analysis, found the association rules of acupoints among 11 randomized controlled trials (RCTs). There were 23 acupoints extracted from 11 RCTs. We used Python to calculate the association between acupoints and disease. We found the top 10 frequency acupoints were Extra12, TF4, LI4, LI11, ST25, ST36, ST44, CO4, CO18, and CO1. We investigated the 1118 association rule and found that {LI4, ST36} ≥ {ST44}, {LI4, ST44} ≥ {ST36}, and {ST36, ST44} ≥ {LI4} were the most associated rules in the data. Acupoints, including LI4, ST36, and ST44, are the core acupoint combinations in the treatment of simple obesity.

Electroacupuncture Upregulates HIF-1α and SOX9 Expression in Knee Osteoarthritis.

Electroacupuncture (EA) has been clinically used in knee osteoarthritis broadly and proved to be effective than other therapies with fewer side effects; however, the mechanism of electroacupuncture to work on cartilage remains unclear. In this study, we aimed to evaluate the effect of EA treatment on cartilage and the relationship between EA and proteins such as HIF-a and SOX9. EA (dilatational wave, 3-15 HZ, 1 mA) has been applied to bilateral Zusanli (ST36), Xuehai (SP10), Taixi (KI3), and Yanglingquan (GB34) of rats. Results showed that the cartilage of the knee osteoarthritis group had obvious damage and fissure formation while the EA group showed that the cartilage destruction was generally milder. In addition, the protein expression levels of HIF-1α, and chondrogenic markers such as Sox9, and ACAN in the electroacupuncture group were higher than those in the ACLT group. Also, the extracellular matrix protein expression levels of MMP13 and ADAMTS5 were decreased in the EA group. These findings indicate that EA could alleviate the severity of knee osteoarthritis, and HIF-a and SOX9 may closely attribute to the treatment.

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.

Chinese Herbal Medicine Decreases Incidence of Cirrhosis in Patients with Non-Alcoholic Fatty Liver Disease in Taiwan: A Propensity Score-Matched Cohort Study.

Objective: Chinese herbal medicine (CHM) is quite popular in Asia. The purpose of this study is to investigate the benefits of decreasing the risk of cirrhosis in patients with non-alcoholic fatty liver disease (NAFLD) by using CHM. Design: We performed a 1:3 propensity score-matched cohort study to analyze patients with NAFLD diagnosed between January 1, 1997 and December 31, 2011 through the Taiwanese National Health Insurance Research Database. Patients who received CHM therapy from the initial date of diagnosis of NAFLD to December 31, 2011 were included in the CHM group. Patients who were not treated with CHM during the same interval were categorized in the non-CHM group. Cox regression model was used to adjust for sex, age, comorbidities, and drug use. Hazard ratios were also compared between the two groups. Results: A total of 13,072 patients were identified after 1:3 propensity score matching. The patients had similar basic characteristics. A lower cumulative incidence of cirrhosis was found in the CHM cohort (log-rank test, p < 0.0001). Finally, 176 patients in the CHM cohort (4.66 per 1000 person-years) and 582 patients in the non-CHM cohort (7.92 per 1000 person-years) developed cirrhosis (adjusted hazard ratios 0.63, 95% confidence interval 0.53-0.75). The effect of CHM to lower cirrhosis incidence was independent of sex, drug use, and comorbidities, including diabetes mellitus, hypertension, and cardiovascular diseases. Patients older than 40 years of age and without comorbidities such as chronic obstructive pulmonary disease, hyperlipidemia, alcoholism, tobacco use, or obesity also benefited from CHM. Conclusions: Our study is the first large-scale investigation in Taiwan that shows the association between patients with NAFLD and cirrhosis prevention after CHM intervention. The results may be useful for treatment and for decision making for patients and clinical doctors. Further restricted trials are needed to support our findings.

[Research on quality difference of standard decoction of raw and fried Paeoniae Radix Alba based on fingerprint and multicomponent determination].

The extract rates, multicomponent content and fingerprint were determined in this study to investigate the quality diffe-rence between standard decoction of raw Paeoniae Radix Alba and fried Paeoniae Radix Alba. UPLC fingerprint was established for 17 batches of standard decoction of raw and fried Paeoniae Radix Alba, and the contents of gallic acid, catechin, albiflorin, paeoniflorin and benzoyl paeoniflorin were determined. The peak areas of standard decoction were analyzed by the independent t-test and orthogonal partial least squares discriminant analysis. There was no significant difference in extract rates between the standard decoction of raw and fried Paeoniae Radix Alba. After fried processing, the content of albiflorin increased by 0.26%, while the contents of gallic acid, catechin, paeoniflorin and benzoyl paeoniflorin decreased by 13.04%, 27.97%, 10.30% and 18.79% respectively. There were 14 common peaks in the fingerprint of standard decoction of raw Paeoniae Radix Alba, and 16 common peaks in the fried Paeoniae Radix Alba. Peak 1 and peak 3 were new ones after processing, among which the peak 3 was 5-hydroxymethylfurfural. The results showed that peak 1, peak 3, peak 11 and peak 15 were the key compounds to distinguish standard decoction of raw and fried Paeoniae Radix Alba. In conclusion, this method is stable and can be used for the study of quantity transfer and quality control in the preparation process of standard decoction, granules and other dosage forms for raw and fried Paeoniae Radix Alba, providing reference for the identification of raw and fried Paeoniae Radix Alba and related preparations.

Thermographic follow-up of postherpetic neuralgia (PHN) subsequent to Ramsay Hunt syndrome with multicranial nerve (V, VII, VIII and IX) involvement: a case report.

BACKGROUND: Ramsay Hunt syndrome (RHS) is caused by a reactivation of varicella-zoster virus (VZV) infection, and it is characterized by the symptoms of facial paralysis, otalgia, auricular rash, and/or an oral lesion. Elderly patients or immunocompromised patients, deep pain at the initial visit and no prompt treatment are significant predictors of postherpetic neuralgia (PHN). When PHN occurs, especially involved cranial polyneuropathy, multiple modalities should be administered for patients with the intractable PHN. The use of thermography in the follow-up of PHN secondary to RHS with multicranial nerve involvement has not yet been described yet in the literature. CASE PRESENTATION: The patient was a 78-year-old man with the chief complaint of a 3-month history of PHN secondary to RHS with polycranial nerve (V, VII, VIII, and IX) involvement. Multimodality therapy with oral gabapentin, pulsed radiofrequency (PRF) application to the Gasserian ganglion for pain in the trigeminal nerve region, linear-polarized near-infrared light irradiation for pain in the facial nerve region, and 2% lidocaine spray for pain in the glossopharyngeal nerve region was used to the treat patient, and follow-up evaluations included thermography. This comprehensive treatment obviously improved the quality of life, resulting in considerable pain relief, as indicated by a decrease in the numerical rating scale (NRS) score from 9 to 3 and a decrease in thermal imaging temperature from higher to average temperature on the ipsilateral side compared with the contralateral side. Lidocaine spray on the tonsillar branches of the glossopharyngeal nerve resulted in an improvement in odynophagia, and the NRS score decreased from 9 to 0 for glossopharyngeal neuralgia after three applications. CONCLUSION: Although the use of thermography in the follow-up of RHS with multiple cranial nerve (V, VII, VIII, and IX) involvement is very rare, in this patient, thermal imaging showed the efficacy of combination therapy (oral gabapentin, 2% lidocaine sprayed, PRF application and linear-polarized near-infrared light irradiation) and that is a good option for treatment.

Mechanisms of Electroacupuncture Pretreatment in Alleviating Myocardial Ischemia Reperfusion Injury: Interactions between the Cerebellar Fastigial Nucleus and Lateral Hypothalamic Area.

Background: Myocardial ischemia reperfusion injury (MIRI) is an important mechanism of post-myocardial infarction injury and a main cause of death in patients with ischemic heart disease. Electroacupuncture (EA) pretreatment is effective for the prevention and treatment of MIRI, but mechanisms mediating the effects of cardiovascular disease EA treatments remain unclear. Objectives: To determine whether the lateral hypothalamus (LHA) and the cerebellar fastigial nucleus (FN) are involved in the protective effects of EA stimulation on MIRI. Methods: EA pretreatment was performed for 7 days before the establishment of the MIRI model. ST-segment changes on electrocardiograms were recorded and the Curtis-Walker arrhythmia score was used to evaluate changes in reperfusion injury. Hematoxylin-eosin staining was applied to evaluate the pathological and morphological changes in myocardial tissue. c-fos expression in the LHA and FN was determined by immunofluorescence staining. Glutamic (Glu) and γ-Aminobutyric acid (GABA) levels were measured using a high-performance liquid chromatography-electrochemical method. Results: EA pretreatment reduced ST-segment elevation, arrhythmia scores, and morphological changes in MIRI myocardial cells in rats, and decreased the c-fos protein expression in LHA/FN nuclei. MIRI was associated with an imbalance between GABA and Glu levels, whereas EA pretreatment increased GABA levels and decreased Glu levels in the LHA/FN. Conclusion: FN and LHA are involved in the EA-mediated attenuation of MIRI. Pretreatment with EA plays a protective role in the myocardium by regulating Glu and GABA release in the LHA and FN.

System optimisation quantitative model of on-line NIR: a case of Glycyrrhiza uralensis Fisch extraction process.

INTRODUCTION: The on-line analysis of active pharmaceutical ingredients (APIs) during the extraction process in herbal medicine is a challenge. Establishing a reliable and robust model is a critical procedure for the industrial application of on-line near-infrared (NIR) technology. OBJECTIVE: To evaluate the advantages of on-line NIR model development using system optimisation strategy, Glycyrrhiza uralensis Fisch was used as a case. The content of liquiritin and glycyrrhizic acid was monitored during pilot scale extraction process of Glycyrrhiza uralensis Fisch in three batches. METHODS: High-performance liquid chromatography (HPLC) was used as reference method for content determination of liquiritin and glycyrrhizic acid. The quantitative models of on-line NIR were developed by system optimisation of processing trajectory. For comparison, the models were simultaneously developed by stepwise optimisation. Moreover, the modelling parameters obtained through system optimisation and stepwise optimisation were reused in three batches. Root mean square error of prediction (RMSEP) and residual predictive deviation (RPD) were used to assess the model quality. RESULTS: The average values of RMSEP and RPD of systematic model for liquiritin in three batches were 0.0361, 4.1525 (first batch), 0.0348, 4.7286 (second batch) and 0.0311, 4.9686 (third batch), respectively. In addition, the modelling parameters of systematic model for glycyrrhizic acid in three batches were same, and the average values of RMSEP and RPD were 0.0665 and 5.2751, respectively. The predictive performance and robustness of systematic models for the three batches were better than the comparison models. CONCLUSION: The work demonstrated that system optimisation quantitative model of on-line NIR could be used to determine the contents of liquiritin and glycyrrhizic acid during Glycyrrhiza uralensis Fisch extraction process.

Effect of acupuncture for methadone maintenance treatment patients: study protocol of a randomized clinical trial.

BACKGROUND: Opioid dependence is an increasing public health problem all over the world. Patients with opioid dependence have to receive methadone maintenance therapy (MMT) as replacement therapy for years or even for their entire life. Acupuncture as a kind of therapy has been used to treat substance dependence for many years. Jin's three-needle acupuncture (JTN), a type of acupuncture technique, has been applied to treat various diseases for several decades. However, JTN as an acupuncture technique has not been used to treat patients receiving MMT. Therefore, we designed a randomized controlled trial to evaluate the efficacy and safety of acupuncture as adjunctive therapy for patients receiving MMT. METHODS/DESIGN: This study is a parallel-arm, randomized controlled trial that aims to evaluate the efficacy and safety of acupuncture as adjunctive therapy for patients receiving MMT. A total of 140 eligible participants who range in age from 18 to 60 years and fulfil the Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-V), for opiate dependence will be enrolled into this study. All eligible participants will be randomly assigned to the acupuncture group or routine group in a 1:1 allocation ratio. Participants who are enrolled in the acupuncture group will receive MMT and JTN treatment for 30 min per session. Meanwhile, those who are assigned to the routine arm will receive MMT only. All 18 sessions of JTN treatment will be delivered over 6 weeks (3 per week) and followed by a 4-week follow-up period. The primary outcome measure will be the visual analogue scale (VAS) for drug craving and the daily consumption of methadone (DCOM). Secondary outcome measures will include the urine test for opioid use, the 36-item Short Form Survey (SF-36), the Beck Anxiety Inventory (BAI), the Beck Depression Inventory II (BDI-II) and Pittsburgh sleep quality index (PSQI). VAS, DCOM, BAI, BDI-II and the urine test for opioid use will be evaluated at baseline, the second week, the fourth week, the sixth week and the tenth week. SF-36 and PSQI will be assessed at baseline, the fourth week, the sixth week and the tenth week. DISCUSSION: The results of this trial will provide evidence on the efficacy and safety of acupuncture as adjunctive therapy for patients receiving MMT.
