Objective To evaluate the efficacy and safety of low?level laser therapy(LLLT)for androgenetic alopecia, and to compare the therapeutic effect of LLLT alone versus in combination with finasteride tablets. Methods Thirty?nine male patients were randomly divided into the LLLT group(n=21)and combination group(n=18)to be treated with LLLT alone or in combination with oral finasteride tablets(1 mg/d)for 6 months. LLLT was given twice a week, and each session lasted 30 minutes. All the patients were photographed and asked to fill a questionnaire about subjective symptoms, and hair density (the number of hairs per unit area on the scalp) was determined by using a dermatoscope to evaluate the grade of alopecia, before the treatment, and 3 and 6 months after the treatment. Results The hair density in the LLLT group was significantly higher after 6 months than after 3 months of treatment and before the treatment(184.59 ± 21.17 vs. 169.24 ± 29.21 and 166.67 ± 32.94 hairs/cm2, both P<0.05), but was insignificantly different between before and after 3 months of treatment (P > 0.05). The hair density in the combination group significantly increased after 6 and 3 months of treatment compared with that before the treatment(201.80 ± 16.55 and 186.39 ± 17.97 vs. 157.85 ± 27.97 hairs/cm2, both P < 0.05), and was significantly higher after 6 months than after 3 months of treatment(P<0.05). No significant difference was observed in hair density between the two groups before the treatment(P>0.05), but the combination group showed increased hair density compared with the LLLT group after 3 and 6 months of treatment(both P<0.05). After 6 months of treatment, LLLT alone was effective in 17 patients, but ineffective in 4 patients, and the combination therapy was effective in 16 patients, but ineffective in 2 patients, with no significant difference in the response rate between the LLLT group and combination group (χ2 = 0.057, P > 0.05). During the treatment, 24(62%)patients felt less greasy, and 22(56%)reported less hair loss, with no discomforts reported by the patients except local warm feeling. Conclusion LLLT is indeed effective for the treatment of androgenetic alopecia with no adverse reactions.

Zusanli (ST 36), Shangjuxu (ST 37) and Xiajuxu (ST 39) are considered as the lower He-sea points, which are located along the leg lines of stomach meridian of foot Yangming from top to bottom. According to the corresponding zang-fu of lower He-sea points, the distribution order from top to bottom is stomach, large intestine and small intestine. This is significantly different from digestive physiology function sequence of stomach, small intestine and large intestine in modern medicine. However, it conforms to their anatomical position from top to bottom. In order to make a further confirmation that the indication specificity of Zusanli (ST 36), Shangjuxu (ST 37) and Xiajuxu (ST 39) is closely associated with anatomical location, a great number of ancient and modern literature is reviewed. It is found that the functions of the three acupoints are obviously related to stomach, large intestine and small intestine, respectively, indicating that the sequence of Zusanli (ST 36), Shangjuxu (ST 37) and Xiajuxu (ST 39) is related to anatomical position of corresponding zang-fu. This study conclusion could play an important role for exploring the significance of anatomical location in indication specificity of acupoints.

BACKGROUND: Biomechanical changes of the trunk might be an important factor contributing to the pathogenesis and poor recovery of lumbar disc herniation.OBJECTIVE: To study the biomechanical changes of the trunk of patients with lumbar disc herniation by isokinetic test of the protruded lumbar disc.DESIGN: Non-randomized controlled retrospective study of concurrent patients.SETTING: Department of Rehabilitation Medicine, Changhai Hospital, Second Military Medical University of Chinese PLA.PARTICIPANTS: Thirty patients with lumbar disc herniation, admitted in the clinic of Department of Rehabilitation, Changhai Hospital affiliated to Second Military Medical University between February 2001 and January 2002, were enrolled in this study, with another 30 concurrent patients without lumbar disc herniation serving as the control group. Informed consent was obtained from all patients involved.METHODS: A Biodex Multi-joint Testing System was employed for measuring the peak torque(PT), peak torque to body weight(PT/BW), time to peak torque(TPT), torque at 0. 2 s(T@ 0. 2), total work(TW), average power(AP) and flexion to extension(F/E) ratio of the trunk muscles of the patients. The results were analyzed by t test using SPSS 9.0 software.MAIN OUTCOME MEASURES: Main outcome: isokinetic evaluation of the lumbar and dorsal flexors and extensors; secondary outcome: F/E ratio.RESULTS: The strength of the trunk flexors and extensors decreased significantly in patients with lumbar disc herniation at each testing speed of retraction, and the bursting strength and indices for work efficiency of the muscles also exhibited obvious changes. The flexors showed greater reduction in muscle strength than the extensors. The F/E ratios during isokinetic concentric contraction at 60°/s and 180°/s were 57.99 ±5.68 and 65.74 ± 8.12, respectively, in patients with lumbar disc herniation, in comparison with the ratios of 95.25 ±5. 18 and 83.03 ±7.61 in the control patients, showing significant difference between the two patient groups( P ＜ 0.01 ).CONCLUSION: Biomechanical changes of the trunk muscles of patients with lumbar disc herniation are definite, and proper rehabilitative treatment of these patients should consists of specific training protocols to restore the mechanical balance of the trunk and break the vicious cycle on the basis ofaccurate evaluation of such changes.

Z-Ligustilide, a major phthalide isolated from a widely used traditional Chinese medicine Ligusticum chuanxiong, possesses various pharmacological activities including neuroprotective, anti-inflammatory, antiproliferative and vasorelaxing effects. However, it is unstable and inclined to degrade in natural conditions, which limits its study and application greatly. In this study, degradation behavior of Z-ligustilide and its degradation products stored at room temperature under direct sunlight were investigated and structure elucidated by HPLC-UV, UPLC-QTOF-MS and NMR. Z-ligustilide degradation and total five degradation products were generated and detected. Two degradation products were unequivocally identified as senkyunolide I and senkyunolide H by comparison with reference compounds. Another two degradation products were further isolated by semi-preparative HPLC and structure elucidated as (E)-6, 7-trans-dihydroxyligustilide and (Z)-6, 7-epoxyligustilide by 1H and 13C NMR, respectively. The degradation pathways of Z-ligustilide were finally proposed. Oxidation, hydrolysis and isomerization are the major degradation reactions.
