Self-Aggregated Nanoscale Metal-Organic Framework for Targeted Pulmonary Decorporation of Uranium.

The limited availability of effective agents for removing actinides from the lungs significantly restricts the effectiveness of medical treatments for nuclear emergencies. Inhalation is the primary route of internal contamination in 44.3% of actinide-related accidents, leading to the accumulation of radionuclides in the lungs and resulting in infections and potential tumor formation (tumorigenesis). This study focuses on the synthesis of a nanometal-organic framework (nMOF) material called ZIF-71-COOH, which is achieved by post-synthetic carboxyl functionalization of ZIF-71. The material demonstrates high and selective adsorption of uranyl, while also exhibiting increased particle size (≈2100 nm) when it aggregates in the blood, enabling passive targeting of the lungs through mechanical filtration. This unique property facilitates the rapid enrichment and selective recognition of uranyl, making nano ZIF-71-COOH highly effective in removing uranyl from the lungs. The findings of this study highlight the potential of self-aggregated nMOFs as a promising drug delivery system for targeted uranium decorporation in the lungs.

[Discussion on "sugar needle - comfortable acupuncture and moxibustion"].

The cases of feeling comfort during acupuncture and moxibustion treatment in literature were summarized and its biological basis was explored. A simple classification of comfort was made, and the importance of obtaining comfort in acupuncture treatment was pointed out. Considering the pursuit of less pain and harmlessness in modern clinical treatment, sugar needle should be advocated and popularized in current clinical practice of acupuncture and moxibustion.

Acupuncture for treatment of knee osteoarthritis: A clinical practice guideline.

CLINICAL QUESTION: Is acupuncture effective in treating knee osteoarthritis (KOA)? CURRENT PRACTICE: Although increasingly used in the clinical setting, acupuncture is not mentioned or weakly recommended in guidelines for the treatment of KOA. RECOMMENDATIONS: We suggest acupuncture rather than no treatment in adult KOA (weak recommendation, moderate certainty evidence), and acupuncture combined with nonsteroidal anti-inflammatory drugs (NSAIDs) rather than acupuncture alone when KOA symptoms are severe (weak recommendation, moderate certainty evidence), with duration of acupuncture for 4-8 weeks depending on KOA severity and treatment response (weak recommendation, moderate certainty evidence), and discussing with patients in shared decision-making. HOW THIS GUIDELINE WAS CREATED: This rapid recommendation was developed following the Making GRADE the Irresistible Choice (MAGIC) methodological framework. First, the clinical specialist identified the topic of recommendation and demand for evidence. Then the independent evidence synthesis group performed a systematic review to summarize available evidence and evaluate the evidence using the GRADE approach. Finally, the clinical specialist group produced recommendations for practice through a consensus procedure. THE EVIDENCE: The linked systematic review and meta-analysis included 9422 KOA patients, 61.1% of whom were women. The median mean age was 61.8 years. Compared with no treatment, acupuncture had beneficial effect on KOA in improving the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) total score (moderate certainty evidence), and WOMAC pain (very low certainty evidence), WOMAC stiffness (low certainty evidence), and WOMAC function (low certainty evidence) subscale scores. Compared with usual care, acupuncture improved WOMAC stiffness subscale score (moderate certainty evidence). Subgroup analyses showed different effects in the improvement of WOMAC total scores by different durations of acupuncture and whether acupuncture combined with NSAIDs, but no difference between manual acupuncture and electroacupuncture was found. UNDERSTANDING THE RECOMMENDATIONS: Compared with no treatment, acupuncture is suggested to reduce pain, stiffness, and disfunction in KOA patients, ultimately improving the patient's health status. Acupuncture can be used as an alternative therapy when usual care is ineffective or there are adverse reactions so that patients can no longer continue the treatment. Manual acupuncture or electroacupuncture is suggested for 4-8 weeks to improve the health status of KOA. The patient's values and preferences should be considered when selecting acupuncture for KOA treatment.

Hinokitiol, an Advanced Bidentate Ligand for Uranyl Decorporation.

Despite the critical role actinide decorporation agents play in the emergency treatment of people in nuclear accidents and other scenarios that may cause internal contamination of actinides, new ligands have seldom been reported in recent decades because the current inventory has been limited to only a handful of functional groups. Therefore, new functional groups are always being urgently sought for the introduction of advanced actinide decorporation agents. Herein, a tropolone derivative, 2-hydroxy-6-(propan-2-yl)cyclohepta-2,4,6-trien-1-one (Hinokitiol or Hino), is proposed to be a promising candidate for this purpose by virtue of its well-demonstrated high membrane permeability and high affinity for metal ions. The coordination stoichiometry of Hino with uranyl is demonstrated to be 3:1 both in an aqueous solution (pH 7.4) and in the solid state. The results of a liquid-liquid extraction experiment further show that Hino exhibits strong chelating ability and selectivity toward uranyl over biological essential metal ions (i.e., Mn2+, Zn2+, Co2+, and Ni2+) with an extraction efficiency of >90.0%. The in vivo uranyl removal efficacies of Hino in kidneys and bone of mice are demonstrated to be 67.0% and 32.3%, respectively. On the basis of the observations described above, it is highly possible that further modification of Hino will lead to a large family of multidentate agents with enhanced uranyl decorporation ability.

[Discussion on Acupuncture as adjunctive therapy for chronic stable angina: a randomized clinical trial published in JAMA Internal Medicine].

Professor LIANG Fan-rong's team from Chengdu University of TCM published Acupuncture as adjunctive therapy for chronic stable angina: a randomized clinical trial in JAMA Internal Medicine on July 29, 2019, which demonstrates that acupuncture as an adjunctive therapy is safety and effective for mild and moderate chronic stable angina. Sixteen experts at home and abroad conducted serious discussions on the research design, evaluation methods, principles and mechanisms, clinical significance and enlightenment of future acupuncture research, and provided practical suggestions for acupuncture and moxibustion to go global and gain international recognition.

Doc Hay: A Chinese Herbalist Combating the 1918-1919 Influenza Pandemic in America.

This is a story about a Chinese herbalist Ing "Doc" Hay who combated the 1918-1919 influenza pandemic in the America West. As an immigrant, he came to the States as a laborer, but he had knowledge of Chinese herbal medicine due to his family heritage. This made it possible for him to start practicing in the Chinese community in John Day, Oregon, until 1948 when he retired. During the time of the pandemic running wild in the 1910s, he prescribed formulas aimed at flu and boiled herbal decoction, personally delivering it to a working site for those Chinese laborers as well as non-Chinese patients. None of the laborer patients treated by him died during this deadly pandemic. Due to his success and fame, his practice was booming even after the Chinese community disappeared in John Day in later years. Doc Hay is always remembered in the history of earlier development in eastern Oregon, so that the site of his practicing, Kam Wah Chung and Co. Building, is now a national historic landmark. And more importantly, he has also been remembered by Chinese herbal medicine practitioners in the United States.

Measure and model a 3-D space-variant PSF for fluorescence microscopy image deblurring.

Conventional deconvolution methods assume that the microscopy system is spatially invariant, introducing considerable errors. We developed a method to more precisely estimate space-variant point-spread functions from sparse measurements. To this end, a space-variant version of deblurring algorithm was developed and combined with a total-variation regularization. Validation with both simulation and real data showed that our PSF model is more accurate than the piecewise-invariant model and the blending model. Comparing with the orthogonal basis decomposition based PSF model, our proposed model also performed with a considerable improvement. We also evaluated the proposed deblurring algorithm. Our new deblurring algorithm showed a significantly better signal-to-noise ratio and higher image quality than those of the conventional space-invariant algorithm.

A new method for quantifying mitochondrial axonal transport.

Axonal transport of mitochondria is critical for neuronal survival and function. Automatically quantifying and analyzing mitochondrial movement in a large quantity remain challenging. Here, we report an efficient method for imaging and quantifying axonal mitochondrial transport using microfluidic-chamber-cultured neurons together with a newly developed analysis package named "MitoQuant". This tool-kit consists of an automated program for tracking mitochondrial movement inside live neuronal axons and a transient-velocity analysis program for analyzing dynamic movement patterns of mitochondria. Using this method, we examined axonal mitochondrial movement both in cultured mammalian neurons and in motor neuron axons of Drosophila in vivo. In 3 different paradigms (temperature changes, drug treatment and genetic manipulation) that affect mitochondria, we have shown that this new method is highly efficient and sensitive for detecting changes in mitochondrial movement. The method significantly enhanced our ability to quantitatively analyze axonal mitochondrial movement and allowed us to detect dynamic changes in axonal mitochondrial transport that were not detected by traditional kymographic analyses.

Statistical analysis of 4 types of neck whiplash injuries based on classical meridian theory.

As one component of the Chinese medicine meridian system, the meridian sinew (Jingjin, (see text), tendino-musculo) is specially described as being for acupuncture treatment of the musculoskeletal system because of its dynamic attributes and tender point correlations. In recent decades, the therapeutic importance of the sinew meridian has become revalued in clinical application. Based on this theory, the authors have established therapeutic strategies of acupuncture treatment in Whiplash-Associated Disorders (WAD) by categorizing four types of neck symptom presentations. The advantage of this new system is to make it much easier for the clinician to find effective acupuncture points. This study attempts to prove the significance of the proposed therapeutic strategies by analyzing data collected from a clinical survey of various WAD using non-supervised statistical methods, such as correlation analysis, factor analysis, and cluster analysis. The clinical survey data have successfully verified discrete characteristics of four neck syndromes, based upon the range of motion (ROM) and tender point location findings. A summary of the relationships among the symptoms of the four neck syndromes has shown the correlation coefficient as having a statistical significance (P < 0.01 or P < 0.05), especially with regard to ROM. Furthermore, factor and cluster analyses resulted in a total of 11 categories of general symptoms, which implies syndrome factors are more related to the Liver, as originally described in classical theory. The hypothesis of meridian sinew syndromes in WAD is clearly supported by the statistical analysis of the clinical trials. This new discovery should be beneficial in improving therapeutic outcomes.

Distribution characteristics of meridian sinew (jingjin) syndrome in 313 cases of whiplash-associated disorders.

OBJECTIVE: To investigate and analyze the characteristics of Meridian Sinew (Jingjin) syndrome in patients with whiplash-associated disorders (WAD). METHODS: From August 2010 to September 2011, 313 WAD cases from New York and California states were collected. The survey mostly collects the information of "Sinew Knotted Points" and symptoms of four types of Meridian Sinew differentiation-Taiyang, Shaoyin, Shaoyang and Yangming. RESULTS: Among the cases which are on the average of medium injury level, the higher frequency of "Sinew Knotted Points" tenderness were found on Jianwaishu (SI 14), Jianzhongshu (SI 15), Tianchuang (SI 16), C3-6 Spinous Process, Dazhui (GV 14), Fengchi (GB 20), Tianliao (SJ 15) and Tianding (LI 17). The most commonly presented symptoms were widespread spasm and tenderness in the neck (Taiyang), difficulty in lateral flexion (Shaoyang), problems of extension and flexion (Taiyang), and stiffness and pain during neck movement (Yangming). Among the cases, 237 cases (75.72%) were related to Taiyang Meridian Sinew syndrome, 82 cases (26.20%) to Shaoyin syndrome and 175 (55.91%) and 176 (56.23%) cases to Shaoyang and Yangming syndrome respectively. The most of cases presented in a combination format. The syndrome distribution under Grade I, II and III reflected that more combination of the Meridian Sinew syndromes in the whiplash injury patients which is resulted from more severity of injury. CONCLUSION: It is practical to identify the location of abnormality through Meridian Sinew differentiation, considering both "Sinew Knotted Points" tenderness and corresponding symptoms, for the local neck symptoms of WAD.

Effective acupuncture practice through diagnosis based on distribution of meridian pathways & related syndromes.

This article discusses the importance of acupuncture practice utilizing diagnosis and distribution of various meridians and connecting channels based on meridian theory. The meridian system is considered as basic anatomy for acupuncture, so the corresponding pathways and related syndromes of different channels should play a key role in differentiation, known as meridian-related pattern differentiation. Since this doctrine originated in ancient times and was not so well developed in later generations, many acupuncturists are not able to utilize it efficiently. The authors survey how this doctrine was weakened during the past century, especially in acupuncture education for foreigners, and how this important method is currently being reinvigorated. This article also lays out the ways this doctrine can be applied clinically and introduces examples of a variety of indications including some difficult cases, such as whiplash injury, intervertebral disc herniation, oculomotor nerve paralysis, and eczema, etc.

[Preliminary study on syndrome differentiation types and acupuncture for whiplash injuries].

Whiplash injury is a relatively common injury of clinical acupuncture and moxibustion in the United States. The mechanism and clinical manifestation of whiplash injuries as well as its pathogenesis described in TCM were analyzed in this present article. The authors introduced the TCM syndrome differentiation of whiplash injuries and claimed that both the location and the stage of disease should be considered. For the different injury locations, the meridian musculature differentiation was applied to classify the whiplash injuries as Taiyang, Yangming, Shaoyang and Shaoyin Meridian syndromes. Considering the duration of the injury, qi stagnation and blood stasis types were classified in the acute stage and phlegm accumulation, insufficiency of the liver and kidney and qi and blood deficiencies types were classified during the chronic stage. An acupuncture protocol for whiplash injuries and typical cases were also introduced.

[Application of palpation in various acupuncture schools of the United States: current status and considerations].

Palpation is one of the major diagnostic methods in Chinese medicine. The article has summed up the current status, features and origins of various palpations in different acupuncture schools in the United States, including palpation on meridian, collaterals and acupoints in traditional Chinese acupuncture, abdominal palpation of Japanese acupuncture, pulse checking for couples in five-element acupuncture, palpation on tendon straps and muscle response testing in acupuncture physical medicine. Since great importance has always been attached on social psychological factors in all acupuncture schools of America, it is thus concluded that the interactive mechanism of diagnosis and treatment represented by palpation feedback examination is not only the manifestation of people oriented individualized treatment both physically and psychologically in America, but also a kind of inheritance and development of diagnosis and treatment in the modernization of TCM.

[Leading role of channel-based syndrome differentiation in acupuncture practice].

Channel-based syndrome (pattern) differentiation has played a leading role in acupuncture practice since the time of Huangdi Nei Jing (The Yellow Emperor's Inner Classic). In the past several decades, however, the clinical application of channel-based syndrome differentiation has begun to diminish, even presenting a substitutional trend by syndrome differentiation of Zangfu organs. The authors elaborate the importance of channel-based pattern differentiation in acupuncture clinic by analyzing its theory from Huangdi Nei Jing and by summing up the methods,clinical significance and application of the basic diagnostic methods-inspection, auscultation and olfaction, interrogation, pulse-feeling and palpation, and measurement of imbalance of the cutaneous electrical and thermal parameters of meridians and acupoints.

Effects of transcutaneous electrical stimulation (1 pulse/sec) through custom-made disposable surface electrodes covering Omura's ST36 area of both legs on normal cell telomeres, oncogen C-fosAb2, integrin alpha5beta1, chlamydia trachomatis, etc. in breast cancer & alzheimer patients.

Our previous study indicated that when extremely reduced normal cell (NC) telomeres in various cancer patients are increased over 500 ng BDORT units, abnormally high cancer cell telomeres and cancer-related markers such as Oncogen C-fosAb2 (Onco.)& Integrin alpha5beta1 (Integ.), & 8-OH-dG as well as bacterial & viral infections, mercury, asbestos, chromium, & beta-amyloid (1-42) markedly reduced due to improved circulation & excretion of these substances in urine. Since 1995, we have been using press-needle stimulation of Omura's ST36 with 200x press-release procedure 4x a day, with significant improvements in various cancer patients. In this study, Transcutaneous Electrical Stimulation (TES) at 60 pulses/min, which is close to patient's heart rate, was given between Omura's ST36 of both legs of the breast cancer & Alzheimer's patients. After about 10 minutes of TES, NC telomeres increased from 1 yg (= 10-24 g) to 500-525 ng; Integ. reduced from 85-75 ng to 0.5 ng & Chlamydia trachomatis (CT) reduced from 4500-3500 ng to 0.5 ng. An additional 10 minutes TES increased NC telomeres to 800-875 ng, while Integ. reduced to 0.5 yg & CT became less than 0.1 yg. After a total 30 minutes of TES, NC telomeres increased to 1000-1200ng BDORT units, with decreases in Integ. and Onco. to less than 0.1 yg. CT reduced to << 0.1 yg. About 24 hours later, NC telomeres were still 300 ng & both Integ. and Onco. were 2.5 ng. CT was approximately 20 ng. In Alzheimer patient, abnormally high beta-Amyloid (1-42) of 7-12 ng markedly reduced to within normal value of less than 1.5 ng by 20-30 min TES. Stimulation beyond 30 minutes gradually reduced NC telomeres. TES pulse rate of 4 pulses/sec for the same patient initially increased NC telomere up to 750-950 ng BDORT units within 20 minutes, but when stimulation continued more than 20 min, NC telomeres rapidly reduced to -150 ng in less than 10 min of TES with reduced beneficial effects.

Anatomical relationship between traditional acupuncture point ST 36 and Omura's ST 36 (True ST 36) with their therapeutic effects: 1) inhibition of cancer cell division by markedly lowering cancer cell telomere while increasing normal cell telomere, 2) improving circulatory disturbances, with reduction of abnormal increase in high triglyceride, L-homocystein, CRP, or cardiac troponin I & T in blood by the stimulation of Omura's ST 36--Part 1.

Using Bi-Digital O-Ring Test Resonance Phenomena between 2 identical substances, Omura, Y. succeeded in making the image of the outline of internal organs without use of standard imaging devices since 1982. When he imaged the outline of the stomach on the abdominal wall, a number of the lines came out from upper and lower parts of stomach wall. When the lines were followed, they were very close to the well-known stomach meridians. Subsequently, he found a method of localizing meridians and their corresponding acupuncture points as well as shapes and diameters accurately. At the anatomical location of ST 36 described in traditional textbooks, Omura, Y. found there is no acupuncture point. However, in the close vicinity, there is an acupuncture point which he named as true ST 36 in the mid 1980s, but it is generally known as Omura's ST 36. When the effects of the acupuncture on these 2 locations were compared, Omura's ST 36 (true ST 36) produced very significant well-known acupuncture beneficial effects including improved circulation and blood chemistry, while in the traditional ST 36, the effects were small. In this article, the anatomical relationship between these two acupuncture points, with a short distance of 0.6 approximately 1.5 cm between the centers of these locations, was described. In early 2000, Omura, Y. found Press Needle Stimulation of Omura's ST 36, using "Press-Release" procedure repeated 200 times, 4 times a day to cancer patients reduced high cancer cell telomere of 600-1500ng and high Oncogen C-fos Ab2 and Integrin alpha5beta1 of 100-700ng BDORT units to close to lyg (= 10(-24) g) BDORT units. In addition there was a significant reduction of Asbestos and Hg from cancer cells, while markedly reduced normal cell telomere of lyg was increased to optimally high amounts of 500-530ng BDORTunits. Thus, cancer cells can no longer divide and cancer activity is inhibited. The authors have successfully applied this method for a variety of cancers as well as for cardio-vascular diseases with hypertriglyceridemia, hyperglycemia, high L-homocystein, and CRP, high cardiac Troponim I & T, and some hypertension. These beneficial effects were accompanied by euphoria, & relaxation with increased alpha waves in EEG. Thus Omura's ST 36 stimulation is a safe, effective and highly desirable supplemental treatment. In addition to manual stimulation, similar beneficial effects can be induced by finger tip stmulation (without any needle) or with electroacupuncture stimulation, (+) Qi Gong energy stored paper and (+) solar energy stored paper which often resulted in significant clinical improvement.
