Objective To investigate the clinical efficacy of acupoint catgut embedding in treating breast cystic hyperplasia of blood stasis-phlegm pattern.Methods One hundred and three patients with breast cystic hyperplasia of blood stasis-phlegm pattern were randomly allocated to a treatment group of 53 cases and a control group of 50 cases. The treatment group received acupoint catgut embedding and the control group took Rupi Sanjie granules. The symptom/sign scores and the qi stagnation transformation score were recorded and sex hormone levels were measured in the two groups before and after 12 weeks of treatment. The clinical therapeutic effects were compared between the two groups.Results The cure rate and the total efficacy rate were 50.9% and 92.5%, respectively, in the treatment group and 46.0% and 90.0%, respectively, in the control group. There were no statistically significant differences in the cure rate and the total efficacy rate between the two groups (P>0.05). There were statistically significant post-treatment differences in the symptom/sign scores (pain, mass hardness, mass range, mass size and accompanying symptoms scores) between the two groups (P<0.05). At the three-month and six-month follow-ups, there were statistically significant differences in the pain, mass range and accompanying symptoms scores as compared with at the end of treatment in the treatment group, and between the treatment and control groups (P<0.05). There was a statistically significant pre-/post-treatment difference in the qi stagnation transformation score in the two groups (P<0.01,P<0.05). There was a statistically significant difference in the qi stagnation transformation score at the three-month and six-month follow-ups compared with at the end of treatment in the treatment group (P<0.05). There was a statistically significant difference in the qi stagnation transformation score between the treatment and control groups at the end of treatment and at the three-month and six-month follow-ups (P<0.05). There was a statistically significant pre-/post-treatment difference in the E2 content in the two groups (P<0.05). There were statistically significant pre-/post-treatment differences in the P and PRL contents in the treatment groups (P<0.05).Conclusion Acupoint catgut embedding is an effective way to treat breast cystic hyperplasia of blood stasis-phlegm pattern.

Objective To study the effects of nitroglycerin on leak point pressure of chronic complete spinal cord injury female rats. Methods Models of chronic complete spinal cord injury in female rats were established. Changes of leak point pressure were investigated following nitroglycerin 3 mg intraperitoneal injection. Results Leak point pressure decreased from (32.27±15.00) cmH2O to (23.29±9.46) cmH2O. Conclusion There was obvious descent of leak point pressure of chronic complete spinal cord injury female rats following nitroglycerin intraperitoneal injection.

Objective To study the effects of nitroglycerin on urethral sphincter of chronic complete spinal cord injury female rats in vitro. Methods 30 SD female rats with 3 months old were transected at T10 spinal cord. After 8 weeks, the 10 rats with BBB scores ≤5 were selected as experimental group, and other 10 normal rats as control group. The difference of tension in both proximal segment (urethral smooth muscle strips) and distal segment (external urethral sphincter muscle strips) were surveyed before and after nitroglycerin 0.5 mg administration in bath. Results The tension of distal segment in control group reduced from (640.50±91.79) mg to (597.50±92.61) mg, and from (485.50±68.94) mg to (459.90±69.51) mg in experimental group. The difference between proximal segment and distal segment were (222.30±12.14) mg and (42.00±7.86) mg before and after administration in control group, and were (223.00±15.78) mg and (25.60±5.17) mg in experimental group. Conclusion The administration of nitroglycerin 0.5 mg in bath can reduce the tension of both urethral smooth muscle and external urethral sphincter in both normal and spinal cord injured rats. The relaxative effect on external urethral sphincter muscle of normal rats exceed that of injured ones, but approximate on urethral smooth muscle.

AIM: To compare the contents of baicalin,paeoniflorin and glycyrrhetic acid in the seperated and mixed decoction of Huangqin Decoction(Radix Scutellariae,Radix Paeoniae alba,Radix et Rhizoma Glycyrrhizae and Fructus Jujubae). METHODS: The contents of baicalin,paeoniflorin and glycyrrhetic acid were analyzed by HPLC.Chromatographic conditions included: Hypersil BDS C_(18) column and the mobile phase consisted of a mixture of methanol-water-phosphoric acid(47(∶)53(∶)0.2),acetonitrile-water-phosphoric acid(18(∶)82(∶)0.1) and methanol-water-phosphate buffer solution(70(∶)29(∶)1).Baicalin,paeoniflorin and glycyrrhetic acid were detected at 280 nm,230 nm and 250 nm respectively. RESULTS: The linear range of baicalin,paeoniflorin and glycyrrhetic acid were 2.88—72.00 ?g/mL,2.85—22.80 ?g/mL and 4.16—52.00 ?g/mL respectively.The contents of baicalin in the mixed decoction was higher than that in the seperated decoction.The contents of paeoniflorin and glycyrrhetic acid in the mixed decoction were almost as same as that in seperated decoction. CONCLUSION: The contents of active ingredients in the mixed and seperated decoction are different.

Objective To study the changes of anticoagulation and fibrinolysis in neonatal respiratory distress syndrome(NRDS).Methods The levels of plasma protein C(PC),total protein S(TPS),antithrombin Ⅲ(AT-Ⅲ), D-Dimer(D-D) and von Willebrand factor(vWF) were measured with ELSIA assay and immunoturbidimetry in 27 cases NRDS, 20 cases prematures and 15 cases full-term newborns as normal controls.Results The levels of PC, TPS and AT-Ⅲ were lower, but the levels of D-D and vWF were significantly higher than those of prematures and normal controls.The PC,TPS of prematures were lower than normal controls otherwise there is no difference of AT-Ⅲ,D-D,vWF between prematures and normal controls. Conclusions There exists the activation of anticoagulation and fibrinolysis and the injury of vascular endothelium in critical NRDS, and they are early sensitive indexes for the diagnosis of disseminated intravascular coagulation(DIC).

OBJECTIVETo assay ligustilide content in the herb of Szechwan Lovage Rhizome (Chuanxiong, CX), which is the dried rhizome of Ligusticum chuanxiong in order to assess the quality.

METHODLigustilide was quantitatively analyzed by high-performance liquid chromatography in 21 CX samples. An Alltima C18 column (4.6 mmx 150 mm, 5 microm) was used as the analytical column. The mobile phase consisted of water and acetonitrile (40:60). The flow rate was maintained at 1.0 mL x min(-1) with the column temperature at ambient conditions. The detection wavelength was set at 350 nm.

RESULTThe average content of Z-ligustilide in 21 CX samples was found to be 7.40 +/- 3.54 mg x g(-1)(x +/- s, n = 21). Therefore,the content of Z-ligustilide in CX should not be less than 0.66% (calculated on the dried basis).

CONCLUSIONThe overall analytical procedure is rapid and accuracy which is considered suitable for the quantitative analysis of ligustilide in CX. The amount of ligustilide in CX samples collected from different cultivation areas was obviously different. However, a relatively higher content of ligustilide was generally found in the CX collected from its main cultivated areas.
