Alkaloid constituents from the fruits of Flueggea virosa / 中国天然药物

Three new indole alkaloids, flueindolines A-C (1-3), along with nine known alkaloids (4-12), were isolated from the fruits of Flueggea virosa (Roxb. ex Willd.) Voigt. Compounds 1 and 2 are two new fused tricyclic indole alkaloids possessing an unusual pyrido[1, 2-a]indole framework, and 3 presents a rare spiro (pyrrolizidinyl-oxindole) backbone. Their structures with absolute configurations were elucidated by means of comprehensive spectroscopic analysis, chemical calculation, as well as X-ray crystallography. Chiral resolution and absolute configuration determination of the known compounds 4, 10, and 11 were reported for the first time. The hypothetical biogenetical pathways of 1-3 were herein also proposed.

Observations on the Efficacy of Electroacupuncture plus a Multi-function Cervical Rehabilitation System in Treating Cervical Spondylosis / 上海针灸杂志

Objective To investigate the clinical efficacy of electroacupuncture plus a multi-function cervical rehabilitation system in treating cervical spondylosis.Methods Sixty patients with cervical spondylosis were randomly allocated to treatment and control groups, 30 cases each. The treatment group received electroacupuncture plus treatment with a multi-function cervical rehabilitation system and the control group, electroacupuncture alone. After 30 days of treatment, changes in the pain score, the neck disability index, and cervical active range of motion and isometric muscle strength were observed in the two groups and the clinical therapeutic effects were compared between the two groups.Results The total efficacy rate was 96.7% in the treatment group and 93.3% in the control group; there was no statistically significant difference between the two groups (P>0.05). There were statistically significant pre-/post-treatment differences in the pain score, the neck disability index, and cervical active range of motion and isometric muscle strength in the two groups (P<0.01,P<0.05). There were statistically significant post-treatment differences in the neck disability index, and cervical active range of motion and isometric muscle strength between the treatment and control groups (P<0.05).Conclusions Electroacupuncture plus a multi-function cervical rehabilitation system is an effective way to treat cervical spondylosis. It can relieve the clinical symptoms in the patients.

Identification of Swertia mussotii and its adulterant Swertia species by 5S rRNA gene spacer / 中国中药杂志

<p><b>OBJECTIVE</b>This research focused on analyzing the differences of 5S rRNA gene spacer sequences on Swertia mussotii and its commonly used adulterants, including S. franchetiana, S. wolfangiana and S. chirayita.</p><p><b>METHOD</b>DNA was extracted from the collected Swertia samples. 5S rRNA intergenic spacers were amplified by PCR, sequenced and analyzed.</p><p><b>RESULT</b>5S rRNA gene spacer sequences were different between S. mussotii and its other three adulterants. Sequence divergence among species ranged from 30.6% to 65.0%.</p><p><b>CONCLUSION</b>5S rRNA spacers may be used as molecular authentication markers to differentiate S. mussotii and other commonly used Swertia adulterants. This result provides reliable and simple reference for the authentication of Swertia genus species.</p>

Chemical constituents and anti-tuberculosis activity of root of Rhodiola kirilowii / 中国中药杂志

The chemical constituents of Rhodiola kirilowii were separated and purified by repeated column chromatography on silica gel, RP - 18, Sephadex LH -20 and semi-preparative HPLC. Each compound was characterized by spectroscopic and physical data. Twelve compounds have been purified and identified to be beta-sitosterol (1), tyrosol (2), trans-hydroxycinnamic acid (3), geranyl beta-glucopyranoside (4), neryl beta-glucopyranoside (5), hexyl beta-glucopyranoside (6), gallic acid (7), (-) -epigallocatechin gallate (8), rhodiolgin (9), isolariciresinol-9-O-beta-glucopyranoside (10), rhodiooctanoside (11), and sacranoside B (12). Among them, compounds 3, 6, 9-12 were isolated from Rhodiola kirilowii for the first time; Compounds 4 and 5 were obtained for the first time from the genus Rhodiola. The in vitro activities against Macobacterium tuberculosis (ATCC 27294) of its extracts and pure components were evaluated by testing their MIC (minimal inhibitory concentration) and MBC (minimal bactericidal concentration). The 80% (a. q.) EtOH extract, EtOAc-soluble extract, compounds 7 and 8 exhibited in-vitro inhibitory and bactericidal activities against Macobacterium tuberculosis in different extent.

Determination of morusin in cortex mori / 中国中药杂志

<p><b>OBJECTIVE</b>To determine the contents of morusin in Sangbaipi (Cortex Mori) of different commercial grades and species and obtained from different regions.</p><p><b>METHOD</b>Contents of morusin were determined by HPLC on an Alltima C18 column (4.6 mm x 250 mm, 5 microm) with acetonitrile-water (58:42) as mobile phase. UV detection was conducted at 270 nm.</p><p><b>RESULT</b>The amounts of morusin were found to vary among samples of Cortex Mori bearing a yellow-brown outer layer and those without the yellow-brown cork layer. The morusin contents were also related to the thickness of Cortex Mori.</p><p><b>CONCLUSION</b>The method was simple, reproducible and reliable. It can be applied to the quality assessment of Cortex Mori.</p>

Clinical Study on Treatment of Shoulder Periarthritis with Electro-acupuncture on Point Jianyu (LI 15) / 针灸推拿医学（英文版）

Objective: To compare the curative efficacy and safety of electro-acupuncture on Jianyu (LI 15) with oral administration of Diclofenac Sodium Sustained-release Capsules in treating shoulder periarthritis. Method: Randomized controlled trials (RCT) were adopted in the study. The patients were randomized into two groups, 30 cases in one group.Electroacupuncture was done on Jianyu (LI 15) 20 min every time in the treatment group,while 75 mg Diclofenac Sodium Sustained-release Capsules were orally administered in the control group. For all the patients in two groups, one treatment course contains 7 days. Then the curative efficacy was evaluated by the efficacy evaluation criteria after two consecutive courses. Result: The total effective rate of treatment group and control group were 93.3% and 56.7% respectively. Conclusion: Electroacupuncture on Jianyu (LI 15) is an effective therapy for shoulder periarthritis and has more significant effect than oral Diclofenac Sodium Sustained-release Capsules.

Clinical Observations on Treatment of Hip Osteoarthritis by Electroacupuncture / 针灸推拿医学（英文版）

To investigate the curative effect of electroacupuncture on hip osteoarth-ritis, 120patients with hip osteoarthritis were randomly divided into two groups, 60 cases each group, and treated by electroacupuncture and oral administration of slow released diclofenac tablet,respectively. The degrees of pain, activity and swelling were observed in both groups before and after treatments. A follow-up was performed for more than 2 years. The curative effects were assessed by JOA criteria for evaluating the effect on hip osteoarthritis. After treatment, the average score increased by 18 marks in the electroacupuncture group and by 12.3 marks in the diclofenac group (P<0.05). Electroacupuncture treatment has a significantly better effect on hip osteoarthritis than oral administration of slow released diclofenac tablet.
