This study was aimed to compare the difference of treatment on acute adjuvant arthritis (AA) by using dif-ferent energy densities withirradiation on ST36-Zusanli under the fixed wavelength (650 nm) by the semiconductor. Biological effect and traits of the laser irradiation were also studied. A total of 60 healthy male SD rats were random-ly divided into the normal control group, model group, low energy density group (61.89 J/cm2)and high energy density group (247.57 J/cm2). The Freund's complete adjuvant (FCA) was intradermallyinjected into rats' right hind paw to establish AA rat model. The treatment group was treated with 650nm semiconductor laser irradiation on ST36-Zu-sanli with the energy density of 61.89 J/cm2 and 247.57 J/cm2, respectively. The joint swelling degree, pain thresh-old, TNF-α and IL-1β level changes were observed on thefirst, third and fifthtreatment after modeling. The results showed that compared with the normal group, the joint swelling degree, pain threshold, TNF-α, and IL-1β were obvi-ously increased in the model group (P<0.05). After five times treatment, the semiconductor laser with low and high energy density had effect on acute inflammation. And the high energy density treatment effect had a better effect than the low energy density one (P<0.05). It was concluded that the energy density of 61.89 J/cm2 and 247.57 J/cm2 of semiconductor laser irradiation on ST36-Zusanli can relieve acute inflammatory pain and swelling caused by AA; re-duce the TNF-α and IL-1β concentration levels. Semiconductor laser irradiation had the characteristics of stimula-tion or inhibition, cumulative effect and parabola. Low energy density group obtained the best effect between the third and fifth treatment.

Objective To explore the mechanism of the cumulative biological effect of acupoint laser radiation and investigate its analgesic effect by comparing the therapeutic effects of semiconductor laser radiation versus acupuncture at point Zusanli(ST36) in acute adjuvant arthritis rats and to provide the experiment-based theoretical foundation and basis for the course of treatment of acute arthritis pain by clinical use of semiconductor laser. Method A rat model of AA was made by subcutaneous injection of complete Freund's adjuvant into rat toe. Eighty rats were randomly allocated to eight groups:model, blank, three-day laser radiation, five-day laser radiation, seven-day laser radiation, three-day acupuncture, five-day acupuncture and seven-day acupuncture treatment groups, 10 rats each. The three laser groups separately received 650 nm semiconductor laser radiation. The three acupuncture groups separately received acupuncture with a filiform needle at point Zusanli(ST36) on the inflammation-affected side. Rat general condition, body weight, pain threshold value and ankle swelling degree were observed. Serum inflammatory factors IL-1、TNF-αand IFN-γcontents were measured by ELISA. Result There were statistically significant posttreatment differences in body weight, joint swelling degree and pain threshold between the laser treatment and acupuncture treatment groups of rats (P<0.05). There was a statistically significant post-treatment difference in joint swelling degree between three-day laser, five-day laser and seven-day laser treatment groups (P<0.05). Pain threshold was lowest at five days after treatment and increased somewhat at seven days after treatment in both the three-day laser and three-day acupuncture treatment groups. The IL-1 content tended to decrease on the whole and had a decreasing tendency at three and five days after treatment in both laser and acupuncture treatment groups. At seven days after treatment, it reached the lowest value in the laser treatment group but had a marked increasing tendency in the acupuncture treatment group. The IFN-γcontent had an increasing tendency at three and five days after treatment in both laser and acupuncture treatment groups. The IFN-γcontent tended to change gently in the laser treatment group from day five to seven after treatment. It tended to decrease from day five to seven after acupuncture treatment but was still higher than in the three-day acupuncture treatment group. The TNF-αcontent tended to decrease from day three to five after treatment in both laser and acupuncture treatment groups. From day five to seven after treatment, it tended to decrease gently in the laser treatment group but tended to increase slightly in the acupuncture treatment group. Conclusion Both semiconductor laser radiation and acupuncture at point Zusanli have an anti-inflammatory and analgesic effect and can relieve the general symptoms in AA rats, but semiconductor laser radiation is significantly superior to acupuncture treatment in eliminating inflammation and easing pain and produces a more timely and better therapeutic effect. After semiconductor laser radiation at acupoints, the related serum cytokines tended to increase or decrease slowly in AA rats after the turning point appeared during the treatment, which embodies the parabola feature of laser radiation treatment. It is showed that with an increase in laser radiation length, the biological effect of laser accumulates, suggesting that attention should be paid to the cumulative effect during laser treatment.

BACKGROUND:Overtraining is a series of functional disorder or pathological state induced by continuous fatigue accumulation because exercise load and body function are incommensurate to each other. At present, commonly used methods for establishing rat models of overtraining included treadmil , swimming and climbing rod, but treadmil is comparatively accepted in the world.
OBJECTIVE:To establish the standard of overtraining rat model and to implement objective of model establishment by dynamical y monitoring biochemical indexes and observing behavioral changes.
METHODS:A total of 16 Sprague-Dawley rats were randomly assigned to model and blank control groups. The model group received movement training according to the plan. After adaptable feeding, training was performed, 6 days every week, with a rest of 1 day. Increasing intensity on treadmil was used. From the first week of training, the speed, gradient and running time were gradual y increased. However, the blank control group was conventional y fed, without any training.
RESULTS AND CONCLUSION:Behavior changes of the training rats were arisen after five weeks. Serum creatine kinase levels increased continuously in training process, and higher than basic levels at 5 weeks (P<0.01). Serum urea nitrogen levels persistently increased, and higher than basic levels at 3 weeks (P<0.05). Hemoglobin and serum testosterone levels increased and then decreased, and significantly lower than basic levels at 8 weeks (P<0.05). Behavioral y, overtraining appeared. Simultaneously, hemoglobin and serum testosterone levels were significantly lower than basic levels. Serum creatine kinase and serum urea nitrogen levels were significantly higher than basic levels. These results indicated that the body was in overtraining state. The standard of overtraining rat model was established in this study. The overtraining rat model was established according to the training program when the training was lasted for 8 weeks, the training speed was 30 m/min;every training time was 110 minutes, and the gradient was 15°.

The questionnaire was adopted so as to investigate the attitudes and recognition of the manufacture eneprises of TCM diagnosis, treatment and rehabilitation equipment (DTRE) to the technical standards of, relevant products. It was found that the construction of the industrial standard and the national standard was lagged behind on TCM DTRE. Under the new situation, the enterprises are highly willing to participate in the development of the industrial, national and international standards and have a certain of understanding on the standard development. Nearly 80 % of enterprises believed that it was necessary to set up the relevant mirror organization for the development of industrial, national and international standard of TCM DITRE. In the future, the standard construction of TCM DTRE must face to the new situation. The constant increasing of the enterprises. and scientific research organizations in the standard construction must promote the development of TCM DTRE.

Objective: To explore the impedance characteristics of ear acupoints in stroke patients with excess or deficiency syndrome, and to provide basis data for objective study of the syndromes of stroke. Methods: The data of electrical characteristics of ear acupoints in stroke patients and healthy people were collected, and excess syndrome and deficiency syndrome of stroke were identified by quantifying the syndromes of stroke using scales. The differences in impedance characteristics of ear acupoints between stroke patients and healthy people were analyzed, and the differences in impedance characteristics of ear acupoints between stroke patients with excess syndrome and stroke patients with deficiency syndrome were analyzed too. The correlation among impedance characteristics of ear acupoints, stroke and the syndromes was also analyzed. Results: There were significant differences in impedance characteristics of ear acupoints between stroke patients and healthy people (P<0.05,P<0.01). The ear acupoints CO12 (Gan) and CO13 (Pi) had a significant role in diagnosing stroke as compared with CO18 (Neifenmi), AT3.4.AH12i (Naogan), CO10 (Shen), TG2p (Shenshangxian), AH6a (Jiaogan), AT4 (Pizhixia), and CO15 (Xin). There were significant differences in impedance characteristics of ear acupoints between stroke patients with excess syndrome and stroke patients with deficiency syndrome (P<0.05, P<0.01). The ear acupoints AH6a (Jiaogan) and CO10 (Shen) played an important role in differentiation diagnosis of excess syndrome and deficiency syndrome of stroke, followed by CO18 (Neifenmi), TF4 (Shenmen) and TG2p (Shenshangxian). Conclusion: Some ear acupoints with diagnostic value for stroke may provide basis of objective research for stroke diagnosis as well as identifying excess syndrome and deficiency syndrome of stroke.

A preliminary investigation on the serum HCV RNA in 182 patients with different chronic liver diseases and 35 blood donors was performed with "nested" polymerase chair reaction.The findings were as follows;(1)Serum HCV RNA was detected in 36.6%(34/93)cases of primary hepatic carcinoma(PHC),31.7%(20/63)cases of liver cirrhosis(LC),15.4%(4/ 26)cases of chronic hepatitis(CH)and 2.9%(1/35)blood donors.(2)Most of the HCV RNA positive cases were accompanied with positive serum HBsAg/HBV DNA.15.1%(14/93)of PHC,3.2%(2/63)of LC and 3.8%(1/26)of CH was positive only for HCV RNA.The findings suggest that about 20% of PHC are related to the coinfection of HCV and HBV,while 15% of PHC are related to HCV infection only.
