Objective To investigate the relationship of matrix metalloproteinases(MMP?3 and MMP?9)and the tissue inhibitor TIMP?1 with left ventricular hypertrophy(LVH)in patients with primary hypertension. Methods Totally 140 patients with primary hypertension and 132 healthy controls were included. Matrix metalloproteinase?3(MMP?3),matrix metalloproteinase?9(MMP?9)and tissue inhibitor metalloproteinase?1 (TIMP?1)were measured. All subjects were taken echocardiography examination ,then left ventricular mass index(LVMI)was calculated. Re?sults MMP?3,MMP?9,TIMP?1(488.32±100.32 vs 314.59±99.78;340.56±43.21 vs 290.15±33.98;389.16±57.53 vs 243.45±62.31;P<0.001) and LVMI(113.7±9.9 vs 88.3±10.4,P<0.001)in patients with primary hypertension were significantly higher than those in controls. In a multiple stepwise regression analysis with LVMI as the variable,it was found that age,SBP,MMP?3,MMP?9 and TIMP?1 were main determinants for LVMI (r2=0.78,P<0.001). 3. Patients with primary hypertension were divided into two subgroups according to LVMI,i.e.,hypertension with LVH (group A)and hypertension without LVH(group B). SBP,MMP?3,MMP?9 and TIMP?1(178±31 vs 166±25;490.14±99.13 vs 405.56±53.12;340.56±43.21 vs 290.15±33.98;393.45±47.69 vs 301.58±39.57;P<0.05)of group A were significantly higher than those of group B. Conclusion MMP?3,MMP?9 and TIMP?1 are influencing factors for LVH in patients with primary hypertension.

Objective To investigate the expression of steroidogenic factor 1 ( SF-1 ) in eutopic endometrium,ovarian endometriosis (EM) and adenomyosis.Methods From Jan.2008 to Dec.2010,30 patients with both ovarian endometriotic cysts and adenomyosis underwent hysterectomy,cystectomy or adenxectomy in Peking University First Hospital.The combination of ovarian EM and denomyosis were confirmed in 17 cases.In the mean time,endometria form 10 patients with cervical intraepithelial neoplasm ( CIN ) Ⅲ underwent hysterectomy were selected as controls.The expression of SF-l in eutopic endometrium,ovarian EM and adenomyosis was detected by immunohistochemistry staining.Results No immunoreactivity of SF-l was observed glandular cell and stromal cell in eutopic endometrium of both groups.14/17 of positive rate of SF-l were observed in lesions of ovarian endometriosis.SF-l protein was not expressed in the endometrial glandular cells of ovarian EM and in adenomyosis foci.Conclusion The differences of SF-l expression in ovarian endometrioma and adenomyosis foci might mediate the development of the disease.

Cell-penetrating peptides (CPPs) offer a non-selective and receptor-independent mode to promote cellular uptake. Although the non-specificity of CPP-mediated internalization allows this approach applicable to a wide range of tumor types potentially, their universality is a significant obstacle to their clinical utility for targeted delivery of cancer therapeutics and imaging agents. Accordingly, many reports have focused on selective switching of systemically delivered inert CPPs into their active form in lesions (tumor). In this review, our attention is mainly confined to such an enzyme-sensitive domain incorporated delivery system with activatable CPPs (ACPPs), which have displayed the exciting strength in balancing the CPPs' pros and cons, and potential in the treatment and diagnosis of some diseases.

OBJECTIVETo explore the clinical efficacy and action mechanism of acupuncture for premature ovarian failure (POF).

METHODSAccording to prospective cohort study design, 30 cases were included. Based on theory of regulating Chong and Conception Vessels as well as soothing the liver and calming the nerves, acupuncture at Guanyuan (CV 4), Dahe (KI 12), Taixi (KI 3), Taichong (LR 3), Baihui (GV 20) was applied, three times per week and 3 months were considered as one session. Totally two sessions were performed. The menstruation condition, estradiol (E2), follicle-stimulating hormone (FSH) and scores of the clinical perimenopausal symptoms were taken as treatment outcomes.

RESULTSThe total effective rate was 86.7% (26/30) and the cured rate was 16.7% (5/30). The recovery rate of menstruation was 16.7% (5/30) and the regain rate of menstruation was 56.7% (17/30). After the treatment, the level of E2 was significantly increased from (45.41 +/- 18. 09) pmol/L to (59.07 +/- 24.21) pmol/L (P < 0.05), and the score of perimenopausal symptoms was obviously reduced from 14.28 +/- 8. 30 to 4.04 +/- 3.28 (P < 0.01). However, no statistical differences could be seen in FSH before and after treatment (P > 0.05).

CONCLUSIONAcupuncture has certain effect on improving menstruation and perimenopausal symptoms in POF patients, which is likely to he related with increasing the level of E2.

Objective To observe expression levels of N-methyl-D-aspartate (NMDA) receptor and cholecystokinin (CCK) in the hippocampus and spinal cord in morphine withdrawal or tolerance mice treated by electroacupuncture or catgut embedding and explore the difference between the regulating effects of electroacupuncture and catgut embedding on morphine withdrawal and tolerance.Methods Fifty-six male C57BL/6J mice were randomly allocated to withdrawal control, withdrawal model, withdrawal catgut embedding and withdrawal electroacupuncture groups, and tolerance control, tolerance model, tolerance catgut embedding and tolerance electroacupuncture groups, 7 mice in each group. A model of morphine withdrawal was made by subcutaneous injection of morphine hydrochloride using 7-day increasing addiction method. The withdrawal control group was injected with an equal volume of normal saline at the same time points. In the withdrawal electroacupuncture group, electroacupuncture at bilateral points Shenshu was performed using a Han’s acupoint nerve stimulation device (HANS-200) at 15 min after an injection of morphine hydrochloride. In the withdrawal catgut embedding group, 0.5 cm chromic catgut was embedded in bilateral points Shenshu at 15 min after an injection of morphine hydrochloride. Addiction was promoted by intraperitoneal injection of naloxone 4 mg/kg at 10 o’clock on the seventh day’s morning and Withdrawal reactions were observed in the mice. The score was recorded using the Ryuta Tomoji opioid withdrawal symptoms evaluation scale. NMDA receptor and CCK contents in the hippocampus and spinal cord were measured by enzyme-linked immunosorbent assay (ELISA). A model of morphine tolerance was made by subcutaneous injection of morphine 10 mg/kg. The tolerance control group was injected with tolerance normal saline 10 ml/kg at the same time. In the tolerance catgut embedding group, catgut was embedded in point Shenshu at the first day after model making. In the tolerance electroacupuncture group, point Shenshu was given electroacupuncture at the first day after model making. After seven days of treatment, NMDA receptor and CCK contents in the hippocampus and spinal cord were measured by ELISA.Results There were statistically significant differences in hippocampal NR2B and CCK expressions between the withdrawal model and withdrawal control groups (P<0.05). There was a statistically significant difference in hippocampal NR2B expression between the withdrawal electroacupuncture and withdrawal model groups (P<0.05). There was a statistically significant difference in hippocampal CCK expression between the withdrawal catgut embedding or withdrawal electroacupuncture group and the withdrawal model group (P<0.05). There were statistically significant differences in spinal cord NR2A, NR2B and CCK expressions between the withdrawal model and withdrawal control groups (P<0.05). There were statistically significant differences in spinal cord NR2A and NR2B expressions between the withdrawal electroacupuncture and withdrawal model groups (P<0.05). There were statistically significant differences in hippocampal NR2A, NR2B and CCK expressions between the tolerance model and tolerance control groups (P<0.05). There was a statistically significant difference in hippocampal CCK expression between the tolerance catgut embedding and tolerance model groups (P<0.05). There was a statistically significant difference in hippocampal NR1 expression between the tolerance electroacupuncture group and the tolerance model or tolerance catgut embedding group (P<0.05). There was a statistically significant difference in spinal cord CCK expression between the tolerance catgut embedding or withdrawal electroacupuncture group and the tolerance model group (P<0.05).Conclusions Both catgut embedding and electroacupuncture at point Shenshu have a reducing effect on morphine tolerance and withdrawal. The therapeutic effect of electroacupuncture is better than that of catgut embedding.

Objective To study the determination method of total flavonoids in Gansu Astragali Radix and Hedysarum Polybotrys. Methods Calycosin glycosides etc. was selected as reference substances, comparison on the difference of absorption curves was done by ultraviolet spectroscopy and colorimetric method (NaNO2-Al(NO3)3-NaOH, AlCl3, Mg(Ac)2, NaOH, phosphomolybdic acid, HCl-Mg power). Results With colorimetric method, the maximum absorption wavelength of referrence and the test was inconsistent. The absorption peak shape was also different. With UV method, Calycosin glycosides in band Ⅱ (260 nm) showed a shoulder absorption. Astragali Radix and Hedysarum Polybotrys also showed characteristic shoulder absorptions in band Ⅱ with absorption wavelength at 263 nm and 265 nm. So the sample absorption wavelength is basically the same as that of the control sample. Conclusion Colorimetries usually used for determination of total flavonoids are not suitable for the comparison determination of Gansu Astragali Radix and Hedysarum Polybotrys. It is suitable for determining the contents of total flavonoids in samples by UV spectrophotometry at the band Ⅱ, which is the characteristic absorption band of isoflavone compound.
