Objective:To investigate the clinical significance of changes of platelet count after splenectomy in patients with cirrhosis and portal hypertension.Methods:In this study,from January 2002 to January 2006,the platelet count and liver function in 153 splenomegaly and hypersplenism due to cirrhosis patients who had been carried out splenectomy were selected.The change tendency of platelet count was observed,the relationship of changes of platelet count and liver function was analysed,and compared with patients of spleen trauma.Results:Postoperative platelet count was higher than preoperatively in most patients with cirrhosis,the portion did not elevate,even decreased.The change tendency of platelet count was correlated with the liver function.The change in cirrhosis patients is not more than patients of spleen trauma.Conclusions:The reason of thrombocytopenia in patients with cirrhosis may be correlated with the change of liver function besides the splenomegaly.

Objective To explore the clinic value and efficacy of color Doppler ultrasound guided percutaneous microwave/radiorequency thermoablation for secondary hyperparathyroidism. Methods Fifty-six cases of secondary hyperparathyroidism who came from nephrology department of Beijing Friendship Hospital in the period of September 2012 to September 2013 were treated by color Doppler ultrasound guided percutaneous microwave/radiorequency thermoablation. One hundred and thirty-eight glands underwent this treatment and were evaluated by contrast enhanced ultrasound before, during and after operation. The levels of serum parathyroid hormone (PTH) were measured before and at 1 week, 1 month, 6 months and 1 year after treatment. Results The whole 56 cases achieved 1 month follow-up and 34 cases and 12 cases achieved 6 months and 1 year follow-up, respectively. Two special cases had been excluded. The PTH levels of 54 cases were signiifcantly different between after and before treatment [(369.5±183.4) ng/L vs (1321.6±471.4) ng/L, t=10.727, P=0.000]. The PTH levels continued to fall at the ifrst week after treatment, but there was no statistical signiifcance between the ifrst week and the ifrst day after treatment [(324.6±172.8) ng/L vs (369.5±183.4) ng/L], while there was signiifcantly different between the ifrst week after treatment and before treatment [(324.6±172.8) ng/L vs (1321.6±471.4) ng/L, t=9.364, P=0.000]. The PTH levels increased from (324.6±172.8) ng/L to (332.5±164.9) ng/L at 1 week and 1 month after ablation, while there was no signiifcant difference.But there is signiifcantly different between 1 month after treatment and before treatment (t=11.348, P=0.000). The PTH level at 6 months after treatment [(205.2±136.3) ng/L] and 1 year after treatment [(177.1±171.5) ng/L] had signiifcant difference compared with the value before treatment (t=8.737, P=0.000; t=7.655, P=0.017). Conclusion Color Doppler ultrasound guided percutaneous microwave/radiorequency thermoablation can be considered as a feasible and effective nonsurgical alternative treatment for secondary hyperparathyroidism patients.

ObjectiveTo explore the effect of Shuanglong pill which can vivid blood and relax thread pulse on cardial morphology and haemodynamics in experimental myocardial infarction (MI) rats.Methods66 rats ligated left coronary artery were randomly divided into large dose group of Shuanglong pill (LDG), small dose group of Shuanglong pill (SDG), the normal control (NC) and the control group of MI. Half in each group received 2 week treatment and the other received 4 week treatment, and were spiled in femoral and common carotid artery respectively. Parameters of cardiac haemodynamics were monitored by eight lead physiological recorder. ResultsLeft ventricular systolic maximum velocity in LDG, SDG and DC was more significantly elevated than in MI, after 2 weeks and 4 weeks of treatment, but it was lower than NC. There were no significant differences among LDG, SDG and DC. Ventricular systolic maximum velocity in LDG was more significantly elevated than in MI after 2 week treatment.ConclusionTreating MI with Shuanglong pill can improve left ventricular systolic maximum velocity, and diastolic phase function of left ventricular also elevate during the acute stage of MI by using large dose.

A new configuration integrated ion exchange effect system with both electro-migration and electrochemical reaction in a single cell was developed to effectively retrieve metal ions from simulated wastewater using ion exchange resins without additive chemicals. By simply assembling cation exchange resins and anion exchange resins separated by homogeneous membranes, we found that the system will always be acidic in the concentrate compartment so that ion exchange resins could be in-situ regenerated without hydroxide precipitation. Such a realizable design will be really suitable for wastewater purification.

OBJECTIVETo compare the efficacy difference in the treatment of chronic pelvic pain syndrome of Sev-damp-heat stagnation pattern between acupoint catgut embedding therapy and western medication.

METHODSenty cases were randomized into a catgut embedding group (40 cases) and a western medication group (30 cases) at the ratio of 4 : 3. In the catgut embedding group, the catgut embedding therapy was applied to Sanyinjiao (SP 6), Quchi (LI 11), Huiyin (CV 1), Zusanli (ST 36), Zhongji (CV 3), Shenshu (BL 23), etc. The treatment was given once every two weeks, the treatment for 4 weeks was as one session and totally 2 sessions were required. In the western medication group, tamsulosin hydrochloride capsules 0. 2 mg, oral administration, once a day, and Indometacin sustained release tablets, 75 mg, once a day, 3 tablets each time were prescribed. The symptom score of TCM, score of NIH Chronic Prostatitis Symptom Index (NIH-CPSI), lecithin body number in prostatic fluid, (SAS) score of Self-Rating Anxiety Scale and score of Self-Rating Depression Scale (SDS) were compared before and after treatment in the patients of the two groups. The efficacy was evaluated in the two groups.

RESULTS(1)The total effective rate was 91. 9% (34/37) in the catgutembedding group and was 86. 2% (25/29) in the western medication group. The efficacy in the catgutembedding group was better than that in the western medication group (P<0. 05). (2) The symptom score of TCM was all reduced significantly after treatment in the two groups (both P<0.01), and the result in the catgut embedding group was superior to the western medication group (6.42 +/-2. 81 vs 10. 99+/-3. 11 ,P<0. 01). (3) Lecithin body number was increased apparently in the two groups after treatment (both P<0.01), and the result in the catgut-embedding group was superior to the western medicine group (33.56+/-5.88 vs 29. 78+/-7. 06,P<0. 05). (4) Total score of NIH-CPSI, score of pain, score of SAS and score of SDS were all improved apparently after treatment in the two groups (all P<0. 01), and the results in the catgut embedding group were superior to the western medication group (P<0. 01, P<0. 05).

CONCLUSIONThe acupoint catgut embedding therapy achieves the superior efficacy on chronic pelvic pain syndrome of damp-heat stagnation pattern as compared with conventional western medicine. This therapy relieves clinical symptoms, improves the states of anxiety and depression and increases lecithin body number obviously.

OBJECTIVETo investigate the relationship of the common Traditional Chinese Medicine (TCM) syndrome pattern of chronic pelvic pain syndrome (CPPS) with the contents of substance p and beta endorphin in the plasma, and provide reference data for the clinical diagnosis, differentiation and treatment of CPPS by TCM.

METHODSWe observed 98 cases of CPPS, which were classified into a lower-part damp-heat invasion group (group A, n = 32), a blood stasis-induced collateral obstruction group (group B, n = 34), and a damp-heat stagnation group (group C, n = 32) according to the TCM syndrome differentiation. Another 35 normal healthy young men were enrolled as controls. We measured the contents of substance p and beta endorphin in the plasma by immunoradiometry and ELISA, and analyzed their relationship with the TCM syndrome pattern.

RESULTSThe contents of plasma substance p were significantly higher in groups A ([1135.76 +/- 166.45] pg/ml), B ([1 337.84 +/- 170.81] pg/ml), and C ([1 210.01 +/- 162.27] pg/ml) than in the control ([574.99 +/- 113.09] pg/ml) (all P < 0.01), while the contents of plasma beta endorphin in groups A ([212.70 +/- 29.49] pg/ml), B ([157.99 +/- 24.01] pg/ml), and C ([180.81 +/- 20.20] pg/ml) were remarkably lower than that in the control ([274.73 +/- 27.64] pg/ml) (all P < 0.01).

CONCLUSIONIn the plasma of CPPS patients, the content of substance p is significantly elevated and that of beta endorphin markedly reduced, which suggests that they may be involved in the inflammatory reaction of CPPS. The levels of plasma substance p and beta endorphin can be used as valuable reference for the TCM classification of chronic prostatitis.
