OBJECTIVES: To compare the clinical effect of combined therapy of acupotomy and electroacupuncture (EA) with the simple application of EA on knee osteoarthritis (KOA), and their influence on knee function. METHODS: Sixty-eight KOA patients were randomly divided into 2 groups, an acupotomy group and an EA group. In the acupotomy group, the combined therapy of acupotomy and EA was adopted. In the EA group, EA was simply used, delivered once every two days, 3 treatments a week；and the duration of treatment was 4 weeks. In the acupotomy group, besides the treatment as the EA group, acupotomy was combined once weekly, and the duration of treatment was 4 weeks. Separately, before and after treatment, and in 4 and 12 weeks after treatment completion (1-month and 3-month follow-up), the results of the timed up and go test (TUG), the 9-step stair climb test (9-SCT) and the knee function (Western Ontario and McMaster University osteoarthritis index visualization scale ［WOMAC］) were measured in the two groups. RESULTS: By the intention-to-treat analysis, the results of TUG, 9-SCT and WOMAC scores were reduced after treatment and in 1-month and 3-month follow-up when compared with those before treatment in the patients of the two groups (P<0.05). Compared with the EA group at the same time point, TUG results were decreased after treatment and in 1-month follow-up, and WOMAC score was reduced after treatment in the acupotomy group. WOMAC score in 1-month follow-up was reduced when compared with that before treatment within the acupotomy group (P<0.05). CONCLUSIONS: Either the simple application of EA or the combined therapy of acupotomy and EA can improve knee function, but the combined therapy obviously increases the walking speed and relieves the symptoms such as joint pain and morning stiffness. The treatment with acupotomy and EA is safe and effective on KOA and the long-term effect is satisfactory.

[Efficacy and mechanism of electroacupuncture on insulin resistant polycystic ovary syndrome].

OBJECTIVE: To explore the therapeutic effect and partial mechanism of electroacupuncture (EA) for patients with insulin resistance (IR) polycystic ovary syndrome (PCOS). METHODS: Seventy patients with IR-PCOS were randomly divided into an EA group (36 cases, 5 cases dropped off) and a medication group (34 cases, 4 cases dropped off). The patients in the medication group were treated with oral administration of metformin hydrochloride, 500 mg each time, twice a day. The patients in the EA group were treated with EA (continuous wave, 2 Hz of frequency) at Zusanli (ST 36), Zhongwan (CV 12), Qihai (CV 6), Yishu (EX-B 3), Shenshu (BL 23), Pishu (BL 20), Ciliao (BL 32) for 30 min, three times a week. One menstrual cycle or 4 weeks were taken as a course of treatment, and 3 continuous courses were given. The follow-up was 3 months. The lipid metabolism indexes of triacylglycerol (TG), total cholesterol (TC), high-density lipoprotein (HDL) and low-density lipoprotein (LDL), homeostasis model assessment-insulin resistance index (HOMA-IR) and testosterone (T) in serum were compared before and after treatment, and the clinical effects of the two groups were evaluated during the follow-up. RESULTS: The total effective rate was 67.7% (21/31) in the EA group and 60.0% (18/30) in the medication group, with no significant difference between the two groups (P>0.05). After treatment, the levels of serum T, HOMA-IR, LDL, TG and TC were decreased significantly in the two groups (P<0.01, P<0.05), and HDL was increased significantly (P<0.01); the levels of TC in the EA group after treatment was lower than that in the medication group (P<0.05). CONCLUSION: EA may adjust some dyslipidemia in patients to correct IR and improve endocrine disorder of PCOS, which had superior/similar effects to metformin.

Potential role of pemetrexed in metastatic breast cancer patients pre-treated with anthracycline or taxane.

OBJECTIVES: This article reviews pharmacology, pharmacokinetic properties, clinical efficacy, and safety in metastatic breast cancer patients, as well as the predictive biomarkers for outcome of treatment with pemetrexed-based regimens. METHODS: PubMed, Embase, OVID, and the Cochrane Library databases were searched from the beginning of each database without any limitations to the date of publication. Search terms were ''pemetrexed'' or ''LY231514'' or "Alimta", "metastatic breast cancer", and "advanced breast cancer". RESULTS: There were 15 studies (n = 1002) meeting our criteria for evaluation. Eight single-agent trials (n = 551) and seven using combinations with other agents (n = 451) were identified that evaluated pemetrexed for use in patients with metastatic breast cancer. Response rates to pemetrexed as a single agent varied from 8% to 31%, and with combination therapy have been reported to be between 15.8% and 55.7%. With routine supplementation of patients with folic acid, dexamethasone, and vitamin B12, the toxicity profile of these patients was mild, including dose-limiting neutropenia and thrombocytopenia, as well as lower grades of reversible hepatotoxicity and gastrointestinal toxicity. Expression of thymidylate synthase (TS) and other biomarkers are associated with the prognosis and sensitivity for pemetrexed in breast cancer. CONCLUSION: Pemetrexed has shown remarkable activity with acceptable toxicities for treatment of metastatic breast cancer patients. Translational research on pemetrexed in breast cancer identified biomarkers as well as additional genes important to its clinical activity and toxicity. Further research is needed to clarify the role of pemetrexed in breast cancer treatment in order to guide oncologists.

[Effect of jianpihuashi decoction on rats with hyperuricemia].

OBJECTIVE: To investigate the effect of Jianpihuashi Decoction on rats with hyperuricemia. METHODS: Forty male Sprague-Dawley (SD) rats were randomly divided into four groups: normal, hyperuricemia, Jianpihuashi Decoction and Allopurinol group. After the administration for 0 day, 10 days, 20 days and 30 days, the serum uric acid, creatinine, urea nitrogen and xanthine oxidase (XOD) activity levels were separately detected using the orbital blood. 30 days after the experiment, the rats were anaesthetized by 3% pentobarbital sodium, liver tissue homogenate extracts were used to detect the XOD activity, and histopathological changes in kidney were observed by HE staining. RESULTS: Treatment with Jianpihuashi Decoction for 30 days, the serum uric acid level of rats with hyperuricemia were significantly decreased (P < 0.05). Simultaneously, the XOD activity in the serum and liver tissue homogenate extracts were obviously decreased by the decoction, which had seldom toxic or side effects on kidney. Allopurinol group could significantly decrease the serum uric acid level, but it had seldom pathological injury to kidney at the same time. CONCLUSION: Jianpihuashi Decoction which has seldom pathological injury to kidney can significantly decrease the effect of uric acid by suppressing XOD activity.

Inhibition of 11b-HSD1 by tetracyclic triterpenoids from Euphorbia kansui.

The roots of Euphorbia kansui are considered an important traditional folk medicine. In this study the ethanol extracts of E. kansui were investigated. A new tetracyclic triterpenoid, euphane-3b,20-dihydroxy-24-ene, in addition to five known triterpenoids with euphane skeletons were isolated. Their structures were elucidated on the basis of physical and spectral techniques (1D-, 2D-NMR and MS, respectively). Furthermore, these compounds 1-6 exhibited strong inhibitory activity against human 11b-hydroxysteroid dehydrogenase type 1 (11b-HSD1), with IC(50) values of 34.86 nM, 1.115 mM, 16.08 nM, 2.815 nM, 26.47 nM, 15.99 nM, and 41.86 nM, respectively. The docking results show that the ring part of compounds can insert into the hydrophobic core of h11b-HSD1 and the alkane chain orientates toward the outside. The results presented herein provide a scientific explanation for the usage of the E. kansui in clinical treatment of diabetes.
