[Infraoccipital needle-knife for cervical vertigo].

OBJECTIVE: To observe the clinical effect differences between infraoccipital needle-knife and massage for cervical vertigo. METHODS: A total of 366 patients with cervical vertigo were randomly assigned into a needle-knife group (186 cases) and a massage group (180 cases). With cases dropping excluded, 183 cases in the needle-knife group and 176 cases in the massage group were included. Needle-knife was used at Fengchi (GB 20), infraoccipital ashi point, etc. in the needle-knife group. The treatment was given for one course, once three days, 5 times as one course. The traditional massage was applied in the massage group for one course, including systematic stroking, kneading, and the application of pressure and plucking, etc., once every two days and 7 times as one course. The dizziness handicap inventory (DHI) score was observed before and after treatment, as well as 3, 6, and 12 months after treatment. The effects were also evaluated. RESULTS: The total effective rate was 92.3% (169/183) in the needle-knife group, which was better than 85.2% (150/176) in the massage group (P<0.05). Compared with those before treatment, the DHI scores at all the observation time points after treatment were improved in the two groups (all P<0.05), with better improvements after treatment as well as 3 and 6 months after treatment in the needle-knife group (all P<0.05). There was no significant difference in the improvement of DHI scores between the two groups 12 months after treatment (P>0.05). The recurrence rate was 10.3% (12/117) in the needle-knife group, and it was 10.7% (11/103) in the massage group 12 months after treatment (P>0.05). CONCLUSIONS: Infraoccipital needle-knife achieves apparent effect for cervical vertigo, which is superior to massage in short period.

Effects of Wenshen Huatan Recipe on the renal function and foe blood lipids of patients with early-middle stage chronic renal insufficiency of Pi-Shen yang deficiency / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To study the clinical effectiveness of Wenshen Huatan Recipe (WHR) in treating early-middle stage chronic renal insufficiency (CRI) of Pi-Shen yang deficiency syndrome (PSYDS).</p><p><b>METHODS</b>Ninety early-middle stage CRI patients of PSYDS were recruited and randomly assigned to the treated group (60 cases) and the control group (30 cases) in the ratio of 2:1. All patients received conventional and symptomatic treatment, but those in the treated group received WHR additionally. The observation was lasted for six months. The total efficacy, the Chinese medicine syndrome integral, and indices of the renal functions [including serum creatinine (SCr), blood urea nitrogen (BUN), creatinine clearance (CCr), serum cystatin C (Cys-C)], blood lipids [total cholesterol (TC), triglyceride (TG), high density lipoprotein cholesterol (HDL-C), and low density lipoprotein cholesterol (LDL-C)], as well as adverse reactions were observed before and after treatment.</p><p><b>RESULTS</b>After six months of treatment, the total effective rate in treated group was 70.0% (42/60), which was obviously higher than that in the control group [43.3% (13/30), P < 0.05]. The Chinese medicine symptoms in the treated group were obviously improved, showing statistical difference between the two groups (P < 0.01). Better effects in lowering SCr, BUN, Cys-C, and LDL-C and increasing CCr were obtained in the treated group than in the control group (P < 0.05).</p><p><b>CONCLUSION</b>WHR could postpone the progression of CRI, improve the lipid metabolism, indicating certain therapeutic efficacy could be obtained in treating early-middle stage CRI from sputum theory.</p>

Determination of vitexin-rhamnoside in Beagle dog plasma and preliminary pharmacokinetics of Yixintong sustained release tablets / 中国中药杂志

<p><b>OBJECTIVE</b>To develop an HPLC method to determine vitexin-rhamnoside in plasma of Beagle dogs and study the pharmacokinetics and bioavailability of Yixintong sustained release tablets in Beagle dogs.</p><p><b>METHOD</b>A newly-developed HPLC method using C18 column and methanol-acetonitrile-tetrahydrogenfuran-0.5% acetic acid (1:1:19.4:78.6) as mobile phase was validated, and then was employed to determine vitexin-rhamnoside in plasma of Beagle dogs after oral administration of Yixintong sustained release tablets and general tablets. The main pharmacokinetic parameters were estimated by pharmacokinetic program 3p87. The non-compartmental pharmacokinetic parameters were also calculated on basis of the statistic moment theory.</p><p><b>RESULT</b>The pharmacokinetic profiles of Yixintong sustained release tablets and the general tablets were fitted to a one-and two-compartment open model, respectively. The T1/2, Tmax, AUC0-infinity and MRT for Yixintong sustained release tablets were 5.22 h, 4.0 h, 6,792.75 ng x h x mL(-1) and 8.4 h, respectively, compared with 8.94 h, 1.0 h, 5,880.4 ng x h x mL(-1) and 6.1 h for the general tablets. The relative bioavailability of the Yixintong sustained release tablets was 115.5% in Beagle dogs.</p><p><b>CONCLUSION</b>The sustained-release characteristic of Yixintong sustained release tablets were confirmed by pharmacokinetic study.</p>

Clinical study on treatment of chronic renal insufficiency based on sputum and blood stasis theory / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To observe the therapeutic effect of Wenshen Huatan Recipe (WHR) on patients with early or middle stage chronic renal insufficiency (CRI) and investigate the clinical validity of applying sputum and blood stasis theory in treating CRI.</p><p><b>METHODS</b>Sixty CRI patients were selected and randomly assigned to the treated group (n = 32) and the control group (n = 28), all received conventional and symptomatic treatment, but those in the treated group were given WHR additionally. Two months were taken as one treatment course and the study lasted for 3 treatment courses. Total effective rate was assessed at the end of the 2nd and 6th month, changes of clinical symptom scores of TCM, and levels of blood urea nitrogen (BUN) and serum creatinine (SCr) in the two groups were observed as well.</p><p><b>RESULTS</b>The total effective rate of the 2nd and 6th month was 68.8% and 75.0% respectively in the treated group and 42.9% and 35.7% in the control group respectively, the difference between the two groups was significant (P < 0.05). Symptoms were improving along with the increasing medication time, and the improvement between the two groups was significant (P<0.01). Levels of SCr and BUN were significantly lowered in the treated group after 2-month and 6-month treatment (P < 0.05, P < 0.01).</p><p><b>CONCLUSION</b>WHR can significantly improve the clinical effect of treatment on CRI during early-middle stage, suggesting that CRI could be treated based on sputum and blood stasis theory with definite clinical efficacy.</p>

[Comparative research of thrombosis animal model induced byendotoxin in combination with carrageenan in different animals].

OBJECTIVE: To compare the development of thrombosis animal model induced by endotoxin(LPS) in combination with carrageenan (Ca) in different animals. METHOD: Two species of rats (SD and Wistar) and three species of mice (Kunming, ICR and Balb/c mice) were employed in the study. The animals of each species were randomly divided into control group and model group (LPS/Ca treatment). The animals in the model group were pretreated with Ca ip at the doses of 25 mg x kg(-1) for rats and 150 mg x kg(-1) for mice, and then treated by LPS iv sixteen hours later, while in the control group were given normal saline (NS). Thrombosis in tails was observed at 24 h after LPS iv. Hematologic parameters were tested for all the animals from each species, and the blood concentration of TNFalpha and IL-6 at different time in SD and Wistar rats were measured. RESULT: LPS/Ca combinatory treatment could induce thrombosis animal model in all five animal species, and the thrombus could be clearly observed on the tails. All species had the similar change in hematologic parameters characterized as the significant decrease of white blood cells and platlets. Inflammatory factors TNFalpha and IL-6 could be largely induced in blood of both SD and Wistar rats at 2 h after LPS iv, but both inflammatory factors only transitorily exist in blood at the early stage of thrombosis model formation. CONCLUSION: LPS/Ca combinatory treatment can successfully induce thrombosis animal model in all tested animal species, and thus this model has extensive animal candidates. The secretion of a large amount of inflammatory factors plays a crucial role in the formation of thrombosis animal model.
