OBJECTIVES: To observe the body surface temperature of the lumbosacral region and relevant back-shu points in patients with lumbar disc herniation (LDH) induced low back pain utilizing infrared thermography, and to explore the functional attribute changes of acupoints under pathological conditions. METHODS: A total of 50 patients with LDH induced low back pain were included as the observation group, and 45 healthy subjects were included as the control group. Using infrared thermography, the body surface temperature of the lumbosacral region and bilateral Sanjiaoshu (BL 22), Shenshu (BL 23), Qihaishu (BL 24), Dachangshu (BL 25), Guanyuanshu (BL 26), Xiaochangshu (BL 27), and Pangguangshu (BL 28) was measured in both groups. The temperature difference values between the bilateral lumbosacral regions and back-shu points of the two groups were calculated. Additionally, the body surface temperature of the affected and healthy sides of the lumbosacral region and relevant back-shu points was compared in the observation group. RESULTS: Compared with the control group, the body surface temperature of the lumbosacral region and the bilateral temperature difference values of the lumbosacral regions were increased in the observation group (P<0.001). The body surface temperature difference values of bilateral Shenshu (BL 23), Qihaishu (BL 24), Dachangshu (BL 25), Guanyuanshu (BL 26) and Xiaochangshu (BL 27) in the observation group were higher than those in the control group (P<0.05, P<0.01, P<0.001). In the observation group, the body surface temperature of the affected side of the lumbosacral region as well as Shenshu (BL 23) and Dachangshu (BL 25) was elevated compared with that of healthy side (P<0.001). CONCLUSIONS: The patients with LDH induced low back pain have imbalanced and asymmetrical distribution of body surface temperature in the lumbosacral region and related back-shu points, Shenshu (BL 23) and Dachangshu (BL 25) have the relative specificity.

Application of Infrared Thermography in the Rehabilitation of Patients in Veterinary Medicine.

Infrared Thermography (IRT) has become an assistance tool in medicine and is used to noninvasively evaluate heat elimination during and after inflammatory processes or during the recovery period. However, its application in veterinary patients undergoing physiotherapy is a field that requires deep research. This review aims to analyze the application of IRT in the monitoring of animal physiotherapy, using the thermal changes that are present in patients undergoing gait or lameness issues (e.g., inflammation, pain, increased local temperature) as a neurobiological basis. Rehabilitation techniques such as acupuncture, physical therapies, thermotherapy, photo-biomodulation, and electrostimulation have been reported to have an anti-inflammatory effect that decreases the amount of local heat production, which is heat that can be recorded with IRT. Therefore, IRT could be used as a complementary tool to evaluate the effectiveness of the therapy, and it is suggested that further studies evaluate the accuracy, sensibility, and sensitivity of IRT.

Effect of Electroacupuncture Stimulation on Brown Adipose Tissue Thermogenesis.

Background: : Brown adipose tissue (BAT) is a unique thermogenic tissue in mammals mediated by uncoupling protein 1 (UCP1). The energy generated by glucose and triglyceride metabolism is released and transmitted throughout the body as heat. Understanding the factors influencing BAT function is crucial to determine its metabolic significance and effects on overall health. Although studies have shown that electroacupuncture (EA) at specific acupoints (e.g., ST36) can stimulate BAT, its effects at other acupoints are not well understood. Further research is needed to investigate the potential effects of EA at these acupoints and their association with BAT activation. Objectives: : This study aimed to investigate the effects of EA at the GV20 and EX-HN3 acupoints. Specifically, the effects of EA on BAT thermogenesis were analyzed by infrared thermography, western blotting, and real-time polymerase chain reaction (PCR). Methods: : A total of 12 C57BL/6J mice were randomly divided into the EA and control groups. The EA group received EA at GV20 and EX-HN3 for 20 min once daily for 14 days. The control group underwent the same procedure but without EA. The core body temperature was monitored. Infrared thermal images of the back of each mouse in both groups were captured. BAT samples were collected after euthanasia to analyze UCP1 protein and UCP1 mRNA. Results: : The average skin temperature in the scapular region of the EA group was increased by 1.1℃ compared with that of the C group (p < 0.05). Additionally, the average temperature along the governor vessel in the EA group was increased by 1.6℃ (p = 0.045). EA significantly increased the expression of UCP1 protein (p = 0.001) and UCP1 mRNA (p = 0.002) in BAT, suggesting a potential link between EA and BAT thermogenesis. Conclusion: : EA induced BAT thermogenesis, suggesting GV20 and EX-HN3 as potential acupoints for BAT stimulation. The experimental results also highlighted unique meridian characteristics as demonstrated by elevated skin temperature along the governor vessel in mice.

Effect of the staging comprehensive treatment with acupuncture-moxibustion on Bell's facial palsy in the acute stage. / 针灸分期综合治疗急性期贝尔面瘫疗效观察.

OBJECTIVES: To compare the clinical effect on Bell's facial palsy in the acute stage between the staging comprehensive treatment with acupuncture-moxibustion and western medication. METHODS: Sixty patients with Bell's facial palsy in the acute stage were randomly divided into an observation group and a control group, with 30 cases in each one. The patients in the control group were administered orally with prednisone acetate tablets and methylcobalamin tablets until the 28th day of illness. In the observation group, the staging comprehensive treatment with acupuncture-moxibustion was adopted. On the affected side, Qianzheng (EX-HN 16), Yifeng (TE 17), Sibai (ST 2), Yangbai (GB 14), Jiache (ST 6), Dicang (ST 4) and Touwei (ST 8), etc. were stimulated. In the acute stage (Day 1 to 7 of illness), the routine acupuncture and the point-toward-point needle insertion were delivered, no any manipulation was exerted at acupoints, and the needles were retained for 30 min. In the subacute stage (Day 8 to 14 of illness), on the base of the treatment as the acute stage, the depth of needle insertion was adjusted at a part of acupoints and the even needling technique was operated by twisting needle. Besides, electroacupuncture (EA) was attached to Qianzheng (EX-HN 16) and Dicang (ST 4), with continuous wave of low intensity and high frequency, 100 Hz, for 20 min. In the recovery stage (Day 15 to 28 of illness), on the base of the treatment as the subacute stage, the heavy stimulation of acupuncture was given, in which, the sticking and lifting needle techniques were delivered after the needles were inserted from Sibai (ST 2) toward Dicang (ST 4), and from Dicang (ST 4) toward Jiache (ST 6), separately; warm needling was operated at Yifeng (TE 17), and EA changed to stimulate the acupoints with the intermittent wave of high intensity and low frequency, 2 Hz, for 30 min. Acupuncture-moxibustion was given once every other day until the end of the 28th day of illness. The level of House-Brackmann facial nerve function rating scale (H-B grade),the score of Sunnybrook facial nerve grading system (Sunnybrook), the score of facial disability index (FDI), the temperature difference in the infrared thermal imaging facial area and electromyogram (EMG) situation of the affected muscle group were observed before and after treatment in the two groups. Using musculoskeletal ultrasound,the facial nerve diameter was detected and the clinical effect was compared between the two groups. RESULTS: After treatment, the level of H-B grade, Sunnybrook score, the scores of physical function and social life function in FDI were improved when compared with those before treatment in the patients of either group (P<0.01, P<0.05), and the results of these evaluations in the observation group were better than those of the control group (P<0.05). After treatment, the temperature difference of the frontal area, the eye area, the zygomatic area and the mouth corner was declined in comparison with that before treatment in the two groups (P<0.05), and the temperature difference in each area in the observation group was lower than that of the control group (P<0.05).The root mean square (RMS) of the frontal muscle group, the zygomatic muscle group and the orbicularis muscle group on the affected side increased in comparison with that before treatment in the two groups (P<0.01), and RMS of the observation group was higher than that of the control group (P<0.05) after treatment. Before treatment, the diameter of the facial nerve on the affected side was larger than that on the healthy side (P<0.01), and after treatment, the diameter on the affected side was reduced when compared with that before treatment in the two groups (P<0.01); the diameter of the facial nerve on the affected side in the observation group was smaller than that of the control group (P<0.05), while, the diameter on the affected side was larger when compared with the healthy side in the control group (P<0.05). The total effective rate of the observation group was 93.3% (28/30), higher than that of the control group (83.3% [25/30], P<0.05). CONCLUSIONS: The staging comprehensive treatment with acupuncture-moxibustion is clearly effective on Bell's facial palsy in the acute stage, which affirms the effectiveness of acupuncture-moxibustion for the acute stage of Bell's facial palsy in comparison with conventional western medication.

Investigating the Therapeutic Effect of Intradermal Acupuncture for Acute Herpes Zoster and Assessing the Feasibility of Infrared Thermography for Early Prediction of Postherpetic Neuralgia: Study Protocol for a Randomized, Sham-Controlled, Clinical Trial.

Introduction: Herpes zoster (HZ) can adversely influence patients' quality of life and sometimes it can develop postherpetic neuralgia (PHN). To date, it remains challenging to be managed by currently available therapies. Intradermal acupuncture (IDA) has the potential to be an adjunctive therapy for acute HZ and infrared thermography (IRT) may be useful for predicting PHN; however, current evidence remains inconclusive. Therefore, the purposes of this trial are to 1) evaluate the efficacy and safety of IDA as an adjunctive therapy for acute HZ; 2) to explore the feasibility of IRT for early prediction of PHN and as an objective tool to aid in subjective pain assessment in acute HZ. Methods: This study is designed as a randomized, parallel-group, sham-controlled, and patient-assessor-blinded trial, including 1-month treatment and 3-month follow-ups. Seventy-two qualified participants will be randomly split into the IDA or sham IDA group in a ratio of 1:1. Apart from standard pharmacological treatments in both groups, the two groups will receive 10 sessions of IDA or sham IDA, respectively. Primary outcome measures are the visual analog scale (VAS), indicators of herpes lesions' recovery, the temperature of the pain area, and the incidence rate of PHN. The secondary outcome is the 36-item Short Form Health Survey (SF-36). Indicators of herpes lesions' recovery will be assessed at each visit and follow-ups. The remaining outcomes will be assessed at baseline, 1 month after intervention, and 3-month follow-up. Safety evaluation will be determined by adverse events during the trial. Conclusion: Expected results will determine whether IDA can enhance therapeutic effectiveness of pharmacotherapy for acute HZ with acceptable safety profile. In addition, it will verify the accuracy of IRT for early prediction of PHN and as an objective tool of subjective pain for acute HZ.

Pilot study: Utility of long-wave infrared thermography as a correlate to transcutaneous oximetry for candidates of hyperbaric oxygen therapy.

Hyperbaric oxygen (HBO2 ) has been used as an adjunctive treatment for the care of advanced non-healing diabetic foot ulcers (DFUs). A patient's in-chamber transcutaneous oximetry measurement (TCOM) is currently the most effective predictor for response to HBO2 therapy but still excludes close to one in four patients who would benefit out of treatment groups when used for patient selection. Improving selection tools and criteria could potentially help better demonstrate HBO2 therapy's efficacy for such patients. We sought to identify if long-wave infrared thermography (LWIT) measurements held any correlation with a patient's TCOM measurements and if LWIT could be used in a response prediction role for adjunctive HBO2 therapy. To investigate, 24 patients already receiving TCOM measurements were enrolled to simultaneously be imaged with LWIT. LWIT measurements were taken throughout each patient's therapeutic course whether they underwent only standard wound care or adjunctive HBO2 treatments. A significant correlation was found between in-chamber TCOM and post-HBO2 LWIT. There was also a significant difference in the post-HBO2 LWIT measurement from 1st treatment to 6 weeks or the last treatment recorded. These initial findings are important as they indicate a possible clinical use for LWIT in the selection process for patients for HBO2 therapy. Larger studies should be carried out to further articulate the clinical use of LWIT in this capacity.

Infrared Thermography for Early Identification and Treatment of Shoulder Sores to Improve Sow and Piglet Welfare.

Shoulder sores in sows cause pain, may lead to early weaning and resultant piglet distress, and premature culling. Early detection and intervention is key to avoid these substantial production and welfare imposts. In this experiment we tested infrared thermography (IRT) to identify shoulder sores before wound eruption, and effectiveness of four wound healing treatments; manuka honey (n = 11); Derisal® (n = 11); Chloromide® (n = 13) and Repiderma® (n = 16), all of which contain no antibiotics. Three hundred and ten sows (parity 2.3 ± 0.2) were monitored daily from entry to the farrowing sheds until weaning using a thermal camera. IRT successfully detected 88% of shoulder sores as hot spots and provided a lead in time of 7 days. Sixteen percent of all sows had a hotspot detected and were randomly allocated to one of four daily treatment groups. At the end of the treatment period, sore diameter was significantly reduced for all treatments, except the Repiderma® group. Sow traits had little influence on susceptibility to shoulder sores. There may be a link between prewean mortality and shoulder sores, but this requires further investigation. The use of IRT to monitor for hotspots for early intervention is validated. Future work should concentrate on methods to prevent wound eruption after detection with IRT to improve the health and welfare of both the sow and her litter.

The Moxibustion-Induced Thermal Transport Effect Between the Heart and Lung Meridians With Infrared Thermography.

Objectives: By comparing the differences in the thermal transport effect between the heart and lung meridians induced by moxibustion, this study aimed to investigate the specificity of site-to-site associations on the body surface between different meridians. Methods: Eighty healthy participants were divided into the heart meridian intervention group and the lung meridian intervention group; moxibustion was performed at these two meridians, respectively. Baseline temperature and its change magnitude from baseline induced by moxibustion in 6 measuring sites of the heart and lung meridians were assessed by infrared thermography (IRT). Measuring sites included: Site 1 (Chize, LU5), Site 2 (midpoint of LU9 and LU5), Site 3 (Taiyuan, LU9), Site 4 (Shaohai, HT3), Site 5 (midpoint of HT7 and HT3), and Site 6 (Shenmen, HT7). Results: Forty participants (20 male and 20 female, 27.90 ± 0.52 years) were assigned to the heart meridian intervention group, and 40 participants (20 male and 20 female, 28.08 ± 0.54 years) were assigned to the lung meridian intervention group. In the lung meridian intervention group (moxibustion over LU5), the temperature of the distal sites in the lung meridian increased significantly at 5, 10, and 15 min compared with pre-moxibustion (P < 0.001). The temperature of Site 4 in the heart meridian, which was nearest to the moxibustion site, increased significantly compared with pre-moxibustion (P < 0.05), while the temperature in the distal sites of the heart meridian did not differ significantly during moxibustion. Regarding the comparison of temperature change magnitude from baseline (ΔT) between the two meridians, the ΔT of Site 2 in the lung meridian was significantly higher than Site 4 in the heart meridian at 5 and 10 min after moxibustion (P < 0.05), despite that Site 2 was more distal from the moxibustion site than Site 4. Similarly, the ΔT of Site 3 in the lung meridian was significantly higher than Site 5 and Site 6 in the heart meridian at 5, 10, and 15 min after moxibustion (P < 0.05). In the heart meridian invervention group, similar thermal transport effect between the two meridians was observed. The thermal transport effect of the distal sites along the heart meridian was more significant than that of the site closer to the moxibustion site but located in the lung meridian. Taken together, aforementioned results indicated that the moxibustion-induced thermal transport effect between the heart and lung meridians is generally more significant in the distal sites along the corresponding meridian than that in the closer sites of the other meridian. Conclusions: In the heart and lung meridians, the moxibustion-induced thermal transport effect is closely related to meridian routes, not just related to the absolute distance from the moxibustion site, thereby confirming the relative specificity of "site-to-site" associations on the body surface in these two meridians.

[Head acupuncture combined with exercise therapy for nonspecific low back pain：a randomized controlled trial].

OBJECTIVE: To compare the clinical effect between head acupuncture combined with exercise therapy and conventional acupuncture for nonspecific low back pain. METHODS: A total of 64 patients with nonspecific low back pain were randomized into an observation group (32 cases, 2 cases dropped off) and a control group (32 cases, 2 cases dropped off). In the control group, conventional acupuncture was applied at Jiaji (EX-B 2) of L1 to L3, ashi point, Shenshu (BL 23), Dachangshu (BL 25), Yaoyangguan (GV 3) and Weizhong (BL 40). The observation group was treated with head acupuncture combined with exercise therapy, head acupuncture was applied at foot-motor-sensory area on the healthy side and Cuanzhu (BL 2), Tongziliao (GB 1) on the affected side, and McKenzie therapy was performed during retention. The needles were retained for 40 min, once a day, continuous treatment for 6 days with the interval of 1 day, 14 days were required in the two groups. Before and after treatment, the pain visual analogue scale (VAS) score, Oswestry disability index (ODI) score and infrared thermography temperature of pain area in the low back were compared in the two groups. RESULTS: Compared before treatment, the VAS and ODI scores after treatment were decreased in the two groups (P<0.01), and those in the observation group were lower than the control group (P<0.01). Compared before treatment, the infrared thermography temperature of pain area in the low back after treatment was increased in the two groups (P<0.01), and that in the observation group was higher than the control group (P<0.01). CONCLUSION: Head acupuncture combined with exercise therapy could relieve pain, improve dysfunction and increase the local temperature of pain area in patients with nonspecific low back pain, and its curative effect is better than conventional acupuncture.

Physically active men with high brown adipose tissue activity showed increased energy expenditure after caffeine supplementation.

This study measured the effect of caffeine on brown adipose tissue (BAT) activity and the energy expenditure (EE) of subjects with high (HBAT) or low (LBAT) activation. We performed a quasi-experimental double-blind protocol in which 24 physically active healthy men were measured (age: 24.1 ± 6.0 yrs; BM: 75.3 ± 14.4 kg; HT: 171.8 ± 5.9 cm; BMI: 25.5 ± 4.9 kg/m2). Infrared thermography (IRT) protocol was used to separate the participants into the groups according to the BAT activation: high (HBAT; n = 11) and low (LBAT; n = 13). All participants ingested a single supplement caffeine capsule (CAF) of 375 mg (~5 mg/kg BM) or placebo (PLA). Our experimental protocol measured two groups (HBAT and LBAT) under two conditions (CAF and PLA), with intake 30-min before the data collection. BAT activity lasted 60-min (0, 10, 20, 30, 40, 50, 60 min) and was estimated by IRT in subclavicular (Δ SCV) and external (Δ EXT) regions of interest (ROI) and EE by indirect calorimetry. The main results indicated that HBAT at 40-min showed an increased EE versus the other groups and conditions (p = 0.009). There was a significant difference for BAT activation at the 30 (p = 0.019), 40 (p = 0.009), 50 (p = 0.007) and 60 min (p = 0.012) between HBAT-CAF vs. LBAT-CAF. There was also a significant difference at the 20 (p = 0.024), 30 (p = 0.036), 50 (p = 0.05) and 60 min (p = 0.011) between HBAT-CAF vs. HBAT-PLA. In conclusion CAF intake (≈5 mg) increases the thermogenic activity of BAT in healthy young men and increases EE in HBAT subjects.

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.

Comparison of acupuncture and acupuncture with infrared thermography-guided Chinese massage in treatment of children with Bell′s palsy / 中华全科医师杂志

Objective:To compare the efficacy between acupuncture and acupuncture with infrared thermography-guided Chinese massage (Tuina) in treatment of children with Bell′s palsy (BP).Methods:Seventy two children with BP admitted to the Rehabilitation Department of Beijing Children′s Hospital from October 2019 to April 2020 were randomly assigned into two groups: 35 cases were treated with acupuncture alone (acupuncture group) and 37 cases received acupuncture combined with Tuina for treatment (combination group). In combination group, the temperature of forehead, cheek and mandible areas was examined by infrared thermography before each course. Compared healthy side if the temperature on the affected side was lower, higher or the same, rubbing method, tapping method and one-finger meditation push method of Tuina was applied, afterwards the acupuncture treatment was given as in the acupuncture group. Patients in both groups were treated once a day with 5 days for a course and a total of 3 courses. The patients were assessed with House-Brackmann (H-B) facial nerve function evaluation scale and Portmann simple score scale before and after each course of treatment.Results:The H-B classification of the two groups of children at the end of the third course of treatment was significantly better than that before treatment (χ2=31.01, 56.41; P<0.01). There was no significant difference in H-B grading between the two groups before treatment, after the first and second course (χ2=0.58, 8.49, 6.79; P>0.05). After the third course of treatment, the H-B grading assessment of the combination group was significant better than that of the acupuncture group (χ2=10.03, P<0.05). The Portmann scores of the two groups were improved after each course of treatment ( F=9.68, 22.54; P<0.01); however, the facial nerve function of combination group was improved more significantly than that of acupuncture group [(13.97±4.58) vs.(10.97±5.40), t=2.55, P=0.01]. The total effective rate of combination group was higher than that of acupuncture group [51.35% (19/37) vs. 20.00% (7/35), χ2=6.79, P<0.05]. There was a significant difference in the application frequency of three Tuina methods among the forehead, cheek and mandibular areas in the first course and the third course (χ2=21.23, 13.33; P<0.05). In the same area (forehead, cheek and mandible) there was a significant difference in the application frequency of three massage techniques among the three courses of treatment (χ2=31.26, 21.35, P<0.01). Conclusion:With the guidance of infrared thermal imaging, individualized Chinese massage (Tuina) combined with acupuncture treatment is more effective in treatment of children with Bell′s palsy than using acupuncture alone.

Activation of brown adipose tissue in diet-induced thermogenesis is GC-C dependent.

Uroguanylin (UGN) is released from the intestine after a meal. When applied in brain ventricles, UGN increases expression of markers of thermogenesis in brown adipose tissue (BAT). Therefore, we determine the effects of its receptor, guanylate cyclase C (GC-C), on mouse interscapular BAT (iBAT) activity during diet-induced thermogenesis (DIT). The activation of iBAT after a meal is diminished in GC-C KO mice, decreased in female wild type (WT) mice, and abolished in old WT animals. The activation of iBAT after a meal is the highest in male WT animals which leads to an increase in GC-C expression in the hypothalamus, an increase in iBAT volume by aging, and induction of iBAT markers of thermogenesis. In contrast to iBAT activation after a meal, iBAT activation after a cold exposure could still exist in GC-C KO mice and it is significantly higher in female WT mice. The expression of GC-C in the proopiomelanocortin neurons of the arcuate nucleus of the hypothalamus but not in iBAT suggests central regulation of iBAT function. The iBAT activity during DIT has significantly reduced in old mice but an intranasal application of UGN leads to an increase in iBAT activity in a dose-dependent manner which is in strong negative correlation to glucose concentration in blood. This activation was not present in GC-C KO mice. Our results suggest the physiological role of GC-C on the BAT regulation and its importance in the regulation of glucose homeostasis and the development of new therapy for obesity and insulin resistance.

Thermal Effects of Acupuncture by the Infrared Thermography Test in Patients With Tinnitus.

Previous studies have confirmed the efficacy of acupuncture treatment for tinnitus. However, no relevant studies of the exact mechanism of acupuncture efficacy on tinnitus have been published. Enrolled participants with left-sided tinnitus received acupuncture treatment at TE3 and TE5. The acupuncture session lasted for 30 minutes. The infrared thermography (IRT) test of each participant's bilateral aural regions and visual analog scale scores were taken before and after the first acupuncture treatment session. Fifty-four participants accepted acupuncture treatment and the IRT test. The temperature differentials of both sides were reduced significantly, but the maximum, minimum, and average temperature of bilateral aural regions did not have a significant difference before and after acupuncture session. The acupuncture's effects for tinnitus were associated with the improvement of cochlear blood flow via the IRT test. We have planned a full-scale randomized controlled trial to find out more about the underlying mechanisms of acupuncture for tinnitus.

Experimental methodology for quantitative assessment of heat-wrap thermal transient behavior.

Among the numerous thermotherapy methods, heat wraps have been largely used over the last 2 decades as a self-administered practice for pain relief. Therefore, understanding their performance has become instrumental within the healthcare industry. However, the majority of the available studies have been focused on in vivo clinical performance, whereas a standardized, quantitative approach to evaluate and compare the various heat-wrap types against each other is lacking. An experimental methodology is proposed to carry out a comparative assessment between heat wraps in terms of their transient thermal behavior. A simple setup was developed to measure wrap/substrate interface temperature trend. The approach was validated by a preliminary infrared-thermography assessment and statistical analysis on the extensive dataset acquired on commercial heat-wrap types for low-back and neck pain relief. The heat-release trend was found to be qualitatively similar over all the investigated types, consisting of rapid growth, stationary phase, decay and end of the reactions. A set of parameters is also proposed to summarize heat-wrap thermal performance.

[Verification of the theory of "Lieque (LU 7) for the disorders of the head and neck" based on infrared thermography].

OBJECTIVE: To verify that whether or not through the effects of the externally and internally related meridians in treatment, Lieque (LU 7) is adopted specially for the disorders of the head and neck. METHODS: A total of 36 healthy volunteers were collected from the students of Gansu University of CM and were divided into a Lieque group and a Jingqu group according to the random number table, 18 cases in each one. In the Lieque group, Lieque (LU 7) on the unilateral side was punctured in the subjects. In the Jingqu group, Jingqu (LU 8) was taken as the control because it was located close to Lieque (LU 7) and on the same meridian. Before and after acupuncture in the two groups, separately, the infrared thermography was adopted to determine the temperature changes at the acupoints of the lung meridian of hand-taiyin, i.e. Jingqu (LU 8), Lieque (LU 7), Kongzui (LU 6), Chize (LU 5) and Tianfu (LU 3) as well as the acupoints of the large intestine meridian of hand-yangming, i.e., Wenliu (LI 7), Shousanli (LI 10), Quchi (LI 11), Shouwuli (LI 13) and Binao (LI 14). RESULTS: After acupuncture stimulation at Lieque (LU 7), the temperature at the acupoints of the lung meridian of hand-taiyin, i.e. Jingqu (LU 8), Lieque (LU 7), Kongzui (LU 6), Chize (LU 5) and Tianfu (LU 3) and the acupoints of the large intestine meridian of hand-yangming, i.e. Wenliu (LI 7), Shousanli (LI 10), Quchi (LI 11), Shouwuli (LI 13) and Binao (LI 14) was all higher obviously as compared with the temperature before acupuncture stimulation (all P<0.05). After acupuncture stimulation at Jingqu (LU 8), the temperature at the acupoints of the lung meridian of hand-taiyin was all increased obviously as compared with the temperature before acupuncture stimulation (all P<0.05), but there was no significant difference in the temperature at the large intestine meridian of hand-yangming (all P>0.05). CONCLUSION: For the disorders of the head and neck, acupuncture at Lieque (LU 7) achieves the stimulation and communication of both the lung meridian and the large intestine meridians, so that it is applicable for the disorders of the externally and internally related meridians.

Estimation the tumor temperature in magnetic nanoparticle hyperthermia by infrared thermography: Phantom and numerical studies.

The treatment of cancer by hyperthermia requires prediction, monitoring and control of the temperature within the tumor. Infrared thermography (IRT) was presented in this paper as a noninvasive temperature monitoring method used in magnetic nanoparticle hyperthermia (MNH). We tried to use this surface temperature measurement method to get information about the intratumoral temperature. Experimental in vitro MNH studies were performed on gel tumor-tissue phantoms which were constructed to simulate the real tumor and overlying healthy tissue. Magnetic nanoparticles were dispersed uniformly in the tumor part of phantom. During the process of in vitro MNH, an alternating magnetic field (AMF) was applied for heating, an IR thermal camera monitored the surface temperature and a fiber optical sensor measured the tumor temperature. A numerical finite element models of thermal analyses was built to simulate the MNH phantom experiments. Both experimental and numerical results indicate that the temperature difference between the surface hot spot and the tumor inner will reach a fixed value while the heating is going on. This value is correlated to factors such as heat generation of hyperthermia, size and depth of the tumor. A regression functions is established to describe the relationship, which is helpful for fast tumor inner temperature estimation by infrared thermography.

New approach for evaluating the effectiveness of whole-body magnetic field therapy in the rehabilitation of patients with lumbar discectomy.

OBJECTIVE: Magnetic field therapy involves the application of low-intensity magnetic fields (1-3.5 mT) to a patient's whole body. The purpose of this study was to assess the effectiveness of whole-body magnetic field (WBMF) therapy in the early rehabilitation of patients after lumbar discectomy. METHODS: A convenience sample of 73 patients who underwent lumbar discectomy within 1 month previously participated in the study. All patients were randomly assigned to one of two groups and received either a course of conventional rehabilitation (control group) or conventional rehabilitation together with 10 sessions of WBMF therapy (WBMF group). Participants were evaluated before and after the rehabilitation course by using the Visual Analog Scale for Pain (VAS) and thermal infrared imaging. The latter was used to detect pathological changes in temperature (hyperthermia and thermal asymmetry) of the surface of the skin overlying the lumbar spine and lower extremities. RESULTS: The VAS score of the WBMF group decreased from 6.2 ± 0.3 cm before to 3.2 ± 0.2 cm after rehabilitation (p< 0.01), compared to 6.1 ± 0.4 cm before to 4.3 ± 0.2 cm after rehabilitation for the control group (p< 0.05). Reduction of the area of lumbar hyperthermia was observed in 88% of WBMF and 35% of control group patients. CONCLUSIONS: When combined with conventional rehabilitation, WBMF therapy was effective in reducing lumbar pain, temperature, and, possibly, inflammation. Results of this study will be used for designing a large-scale clinical trial.
