OBJECTIVETo investigate the effectiveness of polycystic ovary syndrome (PCOS) of damp-phlegm constitution treated with embedding therapy on back-shu points and front-mu points and needle-pricking therapy on Sifeng (EX-UE 10).
METHODSEighty-five patients were randomly divided into 2 groups of observation group (42 cases) and control group (43 cases). Embedding therapy on back-shu points and front-mu points and needle-pricking therapy on Sifeng (EX-UE 10) were applied to the observation group. Points such as Zhongwan (CV 12), Guanyuan (CV 4), Tianshu (ST 25), Zhangmen (LR 13), Jingmen (GB 25), Qimen (LR 14), Ganshu (BL 18), Weishu (BL 21), Pishu (BL 20), Shenshu (BL 23), Dachangshu (BL 25) and Xiaochangshu (BL 27), etc. were adopted for embedding therapy. At the same time, needle-pricking therapy on Sifeng (EX-UE 10) was also applied once a week. 0. 5 g metformin hydrochloride tablet was given to the control group, once a day for the first week, and twice a day from the second week. Estimation on therapeutic effect was made for both groups after 3 months treatment. Change of symptoms and signs scores, fasting insulin (FINS), 2 hour insulin after meal (2hINS) and insulin resistance index (HOMA-IR) of both groups before and after treatment were observed, and therapeutic effect estimated.
RESULTSThe total effective rate of the observation group is 97. 6% (41/42), and that of the control group was 95. 4% (41/43). There was no significant difference between the two groups (P>0. 05). Scores of symptoms and signs after treatment were significantly improved in both groups (all P<0. 01), and the observation group was better than the control group (7.01+/-4.23 vs 8. 47+/-2. 82,P<0. 05). Compare with those before the treatment, FINS, 2hINS and HOMA-IR after the treatment were all decreased in both groups (all P<0. 05). The comparison between the two groups showed that differences of FIN had no statistic significance (P>0. 05) after the treatment, while both differences of 2hINS and HOMA-IR had statistic significance [ 2hlNS: (443. 531+/- 93. 90) pmol/L vs (621.29+/-93. 87) pmol/L ; HOMA-IR: 4. 88+/-0. 30 vs 5.06+/-0. 32, both P<0. 05]. The improvement of 2hINS and HOMA-IR in the observation group was better than that of the control group.
CONCLUSIONTreatment of PCOS of damp-phlegm constitution with embedding therapy on back-shu points and front-mu points and needle-pricking therapy on Sifeng (EX-UE 10) have positive effect, which can effectively reduce the insulin resistance, meanwhile, reduce the side-effects of western medication.

World Science and Technology-Modernization of Traditional Chinese Medicine 2014;(7):1470-1475
So far, an evaluation system for the patent value of traditional medicine is in absence. For this reason, an evaluation system had been established in this paper, by taking advantage of unique attributes of traditional medicine. This system consisted of 10 key indexes equipped with the algorithm for the calculation of original value and comparative value. The comparative value of patent was easier to show the value difference among patents. In consideration of strong correlation between the legal value, technical value, and economic value of the patent and be-tween evaluation indexes thereof, three kinds of value were combined together without discrimination for integral e-valuation. Besides, with inclusion of specific indexes in this field, the non-specific indexes related or indexes un-available were excluded. Because there is no personal rating involved, this evaluation system is appropriate for the automatic evaluation of patents of traditional medicine and other fields .

Chinese Traditional and Herbal Drugs 2013;44(8):1013-1016
Objective: To observe the effects of the early intervention with Didang Decoction (DDD) on macroangiopathy in type 2 diabetic rats. Methods: The type 2 diabetic rat model was established using high-fat diet and Streptozotocin (STZ), and the rats were divided into control, model, Pioglitazone (2.7 mg/kg), Simvastatin (1.8 mg/kg), early-, mid-, and late-term DDD-intervene groups (ig administered with 3.24 g/kg DDD once daily, before 4 weeks, at the same time, and after 4 weeks of STZ administration, respectively), the rats in each group were administered until 24 weeks of STZ administration. The immunohistochemical and pathological changes of intercellular cell adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-1) in the aorta were observed, and the expression of nuclear factor-kappa B (NF-κB) and matrix metalloproteinases-9 (MMP-9) in aorta was detected using Western blotting. Results: Compared with the model group, the ICAM-1 expression decreased in early- and mid-term DDD-intervene groups, and Simvastatin group (P < 0.05), the VCAM-1 expression decreased in early-term DDD-intervene and Simvastatin groups (P < 0.05), the protein expression of NF-κB and MMP-9 was lower in early- and mid-term DDD-intervene groups (P < 0.05), and it is the most obvious in early-term DDD-intervene group. Conclusion: The contents of ICAM-1 and VCAM-1 as well as the protein expression of NF-κB and MMP-9 in type 2 diabetic rats decrease after early-term DDD-intervene, which could regulate NF-κB signaling pathway to delay the development of diabetic macroangiopathy.

Objective To evaluate the value of grey scale ultrasonography (US) combined with elastography in the difference diagnosis of benign and malignant thyroid lesions. Methods Sixty-two patients with 81 lesions were examined by grey scale US and elastography preoperatively. All the lesions were confirmed by pathology. According to their features of grey scale ultrasonograms and elastograms, two receiver operating characteristic (ROC) curves were drawn, one for gray ultrasound and one for the combination methods. The area under curve (AUC) of them were made a comparison. Results The cut-off value of the grey scale group was equal or more than 5, the sensitivity,specificity was 60. 0% ,98. 5%. And the cut-off value of grey scale US combined with elastography group was equal or more than 6, the sensitivity, specificity was 80.0%, 89.4%. The AUC of grey scale US was 0.860 and that of the combination group was 0. 916. The difference between them was statistically significant Z = - 7. 863, P = 0. 000). Conclusions The grey scale US combined with elastography could improve sensitivity and decrease omission diagnose rate. It may be more helpful in the difference diagnosis of malignant from benign thyroid lesions.
