Effect of low-level laser therapy on tooth-related pain and somatosensory function evoked by orthodontic treatment

Low-level laser therapy(LLLT) may have an effect on the pain associated with orthodontic treatment. The aim of this study was to evaluate the effect of LLLT on pain and somatosensory sensitization induced by orthodontic treatment. Forty individuals(12–33 years old; mean ± standard deviations: 20.8 ± 5.9 years) scheduled to receive orthodontic treatment were randomly divided into a laser group(LG) or a placebo group(PG)(1:1). The LG received LLLT(810-nm gallium-aluminium-arsenic diode laser in continuous mode with the power set at 400 mW, 2 J·cm–2) at 0 h, 2 h, 24 h, 4 d, and 7 d after treatment, and the PG received inactive treatment at the same time points. In both groups, the non-treated side served as a control. A numerical rating scale(NRS) of pain, pressure pain thresholds(PPTs), cold detection thresholds(CDTs), warmth detection thresholds(WDTs), cold pain thresholds(CPTs), and heat pain thresholds(HPTs) were tested on both sides at the gingiva and canine tooth and on the hand. The data were analysed by a repeated measures analysis of variance(ANOVA). The NRS pain scores were significantly lower in the LG group(P = 0.01). The CDTs,CPTs, WDTs, HPTs, and PPTs at the gingiva and the PPTs at the canine tooth were significantly less sensitive on the treatment side of the LG compared with that of the PG(P < 0.033). The parameters tested also showed significantly less sensitivity on the nontreatment side of the LG compared to that of the PG(P < 0.043). There were no differences between the groups for any quantitative sensory testing(QST) measures of the hand. The application of LLLT appears to reduce the pain and sensitivity of the tooth and gingiva associated with orthodontic treatment and may have contralateral effects within the trigeminal system but no generalized QST effects. Thus, the present study indicated a significant analgesia effect of LLLT application during orthodontic treatment.Further clinical applications are suggested.

Effect of microenvironment modulation on stem cell therapy for spinal cord injury pain

Spinal cord injury （SCI） currently ranks second after mental retarda- tion among neurological disorders in terms of cost to society. Pain is a debilitating consequence of SCI related to the nature of the lesion, neurological structures damaged, and secondary pathophysiological changes of surviving tissues （Yezierski, 2005; D＇Angelo et al., 2013）.

Effects of cancer therapy on hippocampus-related function

Cancer treatments such as chemotherapy and radiotherapy are widely used to treat primary and metastatic cancers.Epidemiological studies have demonstrated that these types of treatment can effectively and successfully extend the lifespan of cancer patients,but they are also associated with various neurological complications such as cognitive deficits, seizures, and emotional problems （Taphoorn and Klein, 2004; Yang and Moon, 2013; Son et al., 2015b）.

Monitoring of Tumor Response to Neoadjuvant Radio-Chemotherapy of Esophageal Carcinoma by F-18-FDG-PET

Introduction: For clinical assessment of neoadjuvant radiochemotherapy of esophageal cancer reliable in-vivo methods are necessary. Therefore, the capabilities of F-18-Fluorodesoxyglucose-PET in comparison to histomorphological grading of tumor regression were studied. Methods: In 33 patients with locally advanced esophageal carcinoma (uT3, uN0-1, cM0) F-18-FDG-PET was performed before and 2 weeks after radiochemotherapy. All tumors were resected by transthoracic en-bloc esophagectomy 3–4 weeks after induction therapy. A subgroup of 11 patients underwent weekly PET scan during neoadjuvant therapy. PET was performed in a dedicated scanner 1.3 h after administration of 370 MBq F-18-FDG. Data analysis based on maximum SUV data derived from individual regions of interest in pre- and posttherapeutic images. PET data were compared to histomorphological grading parameters for tumor regression whithin the resected tissues. Results: The comparison of histopathological tumor regression after neoadjuvant therapy and PET SUV di?erences showed a signi?cant χ2 P -value of 0.006. There was a signi?cant decrease 五笔字型计算机汉字输入技术 of the SUV data from 9.1±3.5 to 4.3±1.9 (P <0.0001). In therapy responders SUV was diminished by 59 % and in non-responders by 34 %. Longitudinal SUV measurement during neoadjuvant therapy showed a strong SUV decrease already after one and two weeks (P =0.021 and 0.003). Conclusion: The recent data of the FDG-PET follow-up after neoadjuvant therapy show that PET is able to predict therapy response. Longitudinal PET data advocate that it may be possible to recognize response also very early during radiochemotherapy.

THERMOLYTIC EFFECT OF MOXIBUSTION AND ITS RELATION TO ACUPOINT RECEPTORS

In the present paper, the effect of moxibustion stimulation (by using a computer automaticallycontrolled condensed light) of Dazhui (GV 14) etc. on auricular temperature changes was observed in the rabbit after intravenous injection of endotoxin. Changes of rabbit’s auricular temperature were sampled and recorded by using a thermistorthermometer (connected with a computer) before and after moxibustion stimulation. Results indicated that moxibustion making the skin temperature reach to 48℃ could inhibit the endotoxininduced lowering reaction of auricular temperature, while moxibustion making the skin temperature of 40℃ had no this effect. It revealed that higherskintemperature moxibustion had a thermolytic effect on bodyfever, which had a close relation mainly with polymodal receptors rather than with temperature receptor. It also demonstrated that endotoxininduced changes of auricular temperature could be used as an index for evaluating the thermolytic effect of moxibustion.

Effect of different therapies of Chinese medicine on the expressions of c-Fos and c-Jun proteins in hippocampus of rats with post-stroke depression

BACKGROUND ： c-fos and c-jun, the important immediate early genes （IEG）, are regarded as the markers for the location and function of neuronal activity, as well as the third signal messengers, they couple the stress stimulation and the gene expression in neuron, and hippocampus is involved in the process of signal transmission after stress stimulation induced depression. OBJECTIVE： To observe the therapeutic effects of Bushen Yiqi （tonifying kidney to benefit qi）, Huoxue Huayu （promoting blood circulation to dissipate blood stasis） and Ditan Kaiqiao （eliminating phlegm for resuscitation） on the expressions of c-Fos and c-Jun proteins in hippocampus and spontaneous behaviors of rats with post-stroke depression （PSD）, and compare the results with those of fluoxetine, which is known to have definite effect on depression. DESIGN： A randomized controlled tna SETTING ： Zhejiang College of Traditional Chinese Medicine MATERIALS ： The trial was completed in Zhejiang College of Traditional Chinese Medicine from January to July in 2003. Fifty-six healthy adult Wistar male rats of clean grade, weighing （250±50） g, were randomly divided into 7 groups with 8 rats in each group： control group, model group, forced swimming group, Bushen Yiqi group; Huoxue Huayu, Ditan Kaiqiao group and fluoxetine group. The Bushen Yiqi Tang contained Renshen, Huangqi, Heshouwu, Gouqi, Shudi, etc., crude drugs 1 800 g/L. The Huoxue Huayu Tang contained Danshen, Chuanxiong, Chishao, Yujin, etc., crude drugs 3 600 g/L. The Ditan Kaiqiao Tang contained Banxia, Danxing, Changpu, Yuanzhi, etc., crude drug 1 000 g/b METHODS： ① Except the control group and forced swimming group, rats in the other groups were made into PSD models by deligating the bilateral common carotid artedes permanently. ② Rats in the control group, model group and forced swimming group were intragastncally perfused by saline （3 mL for each time）; those in the Bushen Yiqi group, Huoxue Huayu, Ditan Kaiqiao group and fluoxetine group were intragastncally perfused with Bushen Yiqi Tang （18 g/kg）, Huoxue Huayu Tang （9 g/kg）, Ditan Kaiqiao Tang （9 g/kg） and fluoxetine （2.5 mg/kg） respectively, once a day. ③ At 55 days after model establishment, rats in the forced swimming group were managed according to the Porsolt＇s method. They were placed in water for 15 minutes, and then taken out and dned, no moving-time within 5 minutes was recorded at drying and 24 hours after drying. ④ Measurement of spontaneous behaviors： Except the forced swimming group, the spontaneous behaviors and activities （including horizontal and vertical movements） of rats were observed with the Open-Field method at 28, 42 and 56 days after administration in the other groups. ⑤ The expressions of c-Fos and coJun proteins in hippocampus were determined with the immunohistochemical method, the relative sectional area ratio and average objective gray value of c-Fos and c-Jun positive cells in hip- pocampus were measured with the computerized image analytical system. MAIN OUTCOME MEASURES： The spontaneous behaviors of rats, the relative sectional area ratio and average objective gray value of c-Fos and c-Jun positive cells in hippocampus were observed. RESULTS： Of the 56 rats, 1 died in the forced swimming group, and finally 55 rats were involved in the analysis of results. ① Results of spontaneous activities： At 28 days, the times of crossing movements were obviously fewer in the model group and fluoxetine group [（69.00±37.01）, （98.11 ±36.68） times/3 minutes] than in the control group [（128.44±16.85） times/3 minutes, P 〈 0.01, 0.05], but those in the Bushen Yiqi group, Huoxue Quyu group and Ditan Kaiqiao group had no obvious differences as compared with those in the control group （P 〉 0.05）. At 42 and 56 days, the times of crossing movements were obviously more in the Bushen Yiqi group, Huoxue Quyu group and Ditan Kaiqiao group [（106.44±31.24）, （117.20±23.95）, （134.80±28.18）, （136.36±40.95） times/3 minutes; （117.33±35.91）, （129.60 ±23.78）, （131.90 ±26.81）, （136.09±28.34） times/3 minutes] than in the model group [（64.00±17.51）, （72.86±20.68） times/3 minutes, P 〈 0.01]. The times of rearing movements had no obvious differences among the groups for the three times （P 〉 0.05）. ② The no moving-time within 5 minutes 24 hours after drying was obviously longer than that at drying in the forced swimming group. ③ The average objective gray values of c-Fos positive cells were not obviously different in the Bushen Yiqi group and Ditan Kaiqiao group from the control group （P 〉 0.05）, but lower in the model group than in the control group （69.84±9.82, 75.78±5.89, P 〈 0.01）, and higher in the forced swimming group than in the control group （85.97±10.99, P 〈 0.01）; all higher in the fluoxetine group, Bushen Yiqi group, Huoxue Quyu group and Ditan Kaiqiao group than in the model group （81.27±10.73, 74.04±8.34, 83.29±9.89, 70.14±4.92, P 〈 0.05-0.01）. The average objective gray values of c-Jun positive cells were obviously lower in the Bushen Yiqi group than in the control group （68.11 ±6.89, 79.58±5.86, P 〈 0.01）, but all higher in the other groups than in the control group （84.68±7.15, 81.34 ±8.36, 97.51±10.55, 85.68±9.25, 86.19±10.98, P 〈 0.05-0.01）; Those were obviously higher in the fluoxetine group, Huoxue Quyu group and Ditan Kaiqiao group than in the model group （P 〈 0.05-0.01 ）, lower in the Bushen Yiqi group than in the model group （P 〈 0.05）, all obviously lower in the Bushen Yiqi group, Huoxue Quyu group and Ditan Kaiqiao group than in the fluoxetine group （P 〈 0.01）. The relative sectional area ratios of c-Fos and c-Jun positive cells had no obvious differences among the groups （P 〉 0.05）. CONCLUSION ： The methods of Bushen Yiqi, Huoxue Quyu and Ditan Kaiqiao can effectively treat PSD in rats, and the results were equivalent with those of fluoxetine, the actions of the above-mentioned drugs may correlated with their regulation to c-Fos and c-Jun expressions in hippocampus. PSD animal models can be successfully established by both permanent deligation of bilateral common carotid arteries and forced swimming, and the models induced by the former has similar basic cerebrovascular lesions as human stroke in clinic.

Heterogeneity of non-alcoholic fatty liver disease: Implications for clinical practice and research activity

Non-alcoholic fatty liver disease(NAFLD)is a heterogeneous condition with a wide spectrum of clinical presentations and natural history and disease severity.There is also substantial inter-individual variation and variable response to a different therapy.This heterogeneity of NAFLD is in turn influenced by various factors primarily demographic/dietary factors,metabolic status,gut microbiome,genetic predisposition together with epigenetic factors.The differential impact of these factors over a variable period of time influences the clinical phenotype and natural history.Failure to address heterogeneity partly explains the sub-optimal response to current and emerging therapies for fatty liver disease.Consequently,leading experts across the globe have recently suggested a change in nomenclature of NAFLD to metabolic-associated fatty liver disease(MAFLD)which can better reflect current knowledge of heterogeneity and does not exclude concomitant factors for fatty liver disease(e.g.alcohol,viral hepatitis,etc.).Precise identification of disease phenotypes is likely to facilitate clinical trial recruitment and expedite translational research for the development of novel and effective therapies for NAFLD/MAFLD.

Anti-tumor effects of combined doxorubicin and siRNA for pulmonary delivery

Direct administration of drugs and genes to the lungs by pulmonary delivery offers a potential effective therapy for lung cancers.In this study,combined doxorubicin（DOX） and Bcl2 siRNA was employed for cancer therapy using polyethylenimine（PEI） as the carrier of Bcl2 siRNA.Most of the DOX and siRNA possessed high cellular uptake efficiency in B16F10 cells,which was proved by FCM and CLSM analysis.Real-time PCR showed that PEI/Bcl2 siRNA exhibited high gene silencing efficiency with 70%Bcl2 mRNA being knocked down.The combination of DOX and siRNA could enhance the cell proliferation inhibition and the cell apoptosis against B16F10 cells compared to free DOX or PEI/Bcl2 siRNA.Furthermore,the biodistribution of DOX and siRNA via pulmonary administration was studied in mice with B16F10 metastatic lung cancer.The results showed that most of the DOX and siRNA were accumulated in lungs and lasted at least for 3 days,which suggested that combined DOX and siRNA by pulmonary administration may have high anti-tumor effects for metastatic lung cancer treatment in vivo.

Knee osteoarthritis treated with acupuncture based on syndrome differentiation:a randomized controlled trial

Objective To compare the efficacy differences between acupuncture and western medicine in treating osteoarthritis of knee joints.Methods One hundred and twenty cases were randomly divided into an acupuncture group and a western medication group with 60 cases in each group.In the acupuncture group,acupuncture was applied mainly at Nèixīyǎn（内膝眼 EX-LE 4）,Dúbí（犊鼻 ST 35）,Yīnlíngquán（阴陵泉 SP 9） and Yánglíngquán（阳陵泉 GB 34） plus other acupoints selected according to syndrome differentiation.In the medication group,Glucosamine Hydrochloride capsules were orally given 3 times daily with 2 capsules each time.Western Ontario and McMaster Universities Osteoarthritis Index（WOMAC）,Medical Outcomes Study 36-Item Short Form Health Survey（SF-36,Chinese version） were used to assess therapeutic effects before treatment,after 4 weeks treatment and 9 weeks after treatment,respectively.Results After 4 weeks of treatment,the total effective rates were 86.7%（52/60） and 88.3%（53/60） in the acupuncture group and the western medication group,respectively,without significant difference（P〈0.05）.In 9 weeks after treatment,the total effective rates were 83.3%（50/60） and 61.7%（37/60） in the acupuncture group and the western medication group,respectively,with significant difference between the two groups（P〈0.05）.According to WOMAC and SF-36,the scores were all improved in both groups（P〈0.05,P〈0.01）,with significant difference in follow-up visit of 9 weeks after treatment between the two groups（P〈0.05,P〈0.01）,but not after 4 weeks of treatments（both P〈0.05）.Conclusion Short-term of therapeutic effects of acupuncture and oral administration of Glucosamine Hydrochloride on osteoarthritis of knee joints are similar,but long-term efficacy in the acupuncture group is better than that in the western medication group.

Clinical Efficacy and Safety of Bathing with Chinese Medicine Taohong Siwu Decoction(桃红四物汤) for Treatment of Diffuse Cutaneous Systemic Sclerosis:A Randomized Placebo-Controlled Trial

Objective：To examine the efficacy and safety of bathing therapy with Taohong Siwu Decoction（桃红四物汤,TSD） in the treatment of early-stage,mild-moderate diffuse cutaneous systemic sclerosis（dc SSc）.Methods：This randomized,placebo-controlled trial enrolled 148 men and women（18–60 years） with dc SSc（disease duration 12 months） and baseline modified Rodnan skin score（MRSS） 10.Patients were randomized into a TSD group（71 cases bathing with TSD plus oral prednisone） or control group（71 cases bathing with placebo plus oral prednisone）.Bathing（40 ℃,30 min） of the upper and lower limbs was carried out once daily for 12 consecutive weeks.The primary outcome measure was MRSS;secondary outcomes were Raynaud＇s phenomenon（RP） score,quality of life（QOL）,physician visual analogue scale（VAS）,patient VAS,percent predicted diffusing capacity for carbon monoxide（DLCO）,percent predicted forced vital capacity（FVC）,erythrocyte sedimentation rate（ESR）,C-reactive protein（CRP） level and overall treatment effect.Results：The final analysis included 135 patients（control group,68 cases;TSD group,67 cases）.Primary and secondary outcome measures after 2 weeks of treatment showed no improvement（versus baseline） in both groups,with no differences between groups.At 12 weeks,QOL,physician VAS,patient VAS,ESR and CRP were improved in both groups,but MRSS and RP score were improved only in the TSD group（all P〈0.05）.MRSS,RP score,QOL,physician VAS,patient VAS,ESR and CRP differed significantly between groups（all P〈0.05）.Meanwhile,the overall treatment effect was significantly higher in the TSD group than in the control group（P〈0.05）.Adverse events in the two groups were similar（P〉0.05）.Conclusions：Bathing with TSD plus oral prednisone achieves better outcomes than oral prednisone alone in patients with dcS Sc and is not associated with serious adverse events.
