Objective To study the effect of chitosan-pCrmA nanoparticles on the apoptosis of chondrocytes induced by interleukin-1 beta (IL-1β).Methods Chitosan-pDNA nanoparticles were prepared and characterized.The transfection efficiency of chitosan-mediated pIRES2-EGFP was evaluated using fluorescence microscope.The cytotoxicity of chitosan-pIRES2-EGFP nanoparticles in primary rabbit chondrocytes was analyzed by MTT assay.The expression of chitosan-mediated pCrmA in primary rabbit chondrocytes was verified by Western blotting.The effect of chitosan-mediated CrmA on chondrocytes apoptosis induced by IL-1β were analyzed by TUNEL assay.One-way ANOVA was used to analysis.Results The size of chitosan-pDNA nanoparticles was 50 nm.The pDNA release of chitosan-pDNA nanoparticles appeared as biphasic release at pH 2.0 and pH 7.4 buffer.The expression of CrmA in rabbit primary chondrocytes mediated by chitosan could be detected.The chitosan-pIRES2-EGFP nanoparticles had no cytotoxicity.The apoptosis rate of chondrocytes in the chitosan-pCrmA nanoparticles treated group was significantly lower than that of the chitosan treated group (P＜0.05) and PBS group (P＜0.01).Conclsion Chitosan is an effective non-viral gene transfer vector.The CrmA mediated by chitosan can significantly inhibit chondrocytes apoptosis induced by IL-1β,suggesting that chitosan-pCrmA nanoparticles may be the treatment of osteoarthrifis.

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.

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.

Objective To observe the effect of β-blocker on dilated cardiomyopathy (DCM) in children.Methods Sixty-one children cases of DCM in this hospital from 1995 to 2015 were retrospectively analyzed and divided into the treatment group(taking β-blocker,n=35) and control group(non-taking β-blocker,n=26) according to whether taking β-blocker.The clinical effect of β-blocker was preliminarily observed.Results The heart rate,LVDD,LVSD and LA after treatment in the treatment group were significantly decreased compared with before treatment(P＜0.05),while EF was significantly increased(P＜0.05);LVDD after treatment in the control group was significantly decreased(P＜0.05),while hear rate,RV,LVDD,LVSD,LA,MV and EF had no obvious change compared with before admission(P＞0.05).The heart rate,LVDD,LVSD and EF after treatment had statistical difference between the treatment group and control group (P＜0.05),the heart function after treatment in the treatment group was significantly improved compared with the control group (P＜0.05).The heart function improvement degree after treatment in the patients with hypertension of the treatment group was significantly better than those with normal blood pressure(P＜0.05).DCM with hypertension was significantly improved after treatment and was better than DCM without hypertension (P＜0.05).The The heart function improvement degree after treatment in the patients with carvedilol treatment was obviously better than that in the patients with metoprolol treatment(P＜0.05).Conclusion β-blocker could be used in the treatment of DCM,its effect is especially good in DCM children patients with hypertension,in which the effect of carvedilol is better than that of metoprolol.

Objective To characterize the clinical manifestations, laboratory findings of patients with occult sys?temic malignant neoplasms, whose initial manifestation presented as multiple acute cerebral infarcts including coagula?tion function,radiological imaging and microembolic signals (MES) detection by transcranial Doppler sonography (TCD) and to explore the possible underlying mechanisms. Methods All clinical records, laboratory hematological tests includ?ing hypercoagulable states measured by D-dimer levels, brain MRI including DWI, and TCD monitoring MES, the treat?ment and prognosis were retrospectively reviewed in 12 patients with multiple acute cerebral infarcts as the first manifes?tation of occult systemic malignancy. Results The clinical manifestations presented as localized neurological dysfunction, e.g. hemiparesis, aphasia, hemiparesthesia, dysarthria, vertigo and seizures, etc. DWI revealed multiple disseminated acute cerebral infarcts in multiple arterial territories such as the bilateral anterior or anterior plus posterior cerebral circu?lation in all patients. Eleven of 12 patients tested had elevated D-dimer. TCD detected MES in 5 of 7 patients. There were 12 patients diagnosed with occult systemic malignancy including 5 lung cancer, 3 pancreatic cancer, 1 gastric can?cer, 1 colon cancer, 1 endometrial adenocarcinoma and 1 metastatic poorly differentiated mucinous adenocarcinoma with unknown primary. Ten patients already had remote metastasis at diagnosis. The prognosis was usually poor and there were 7 cases with ischemic stroke recurrence, 4 cases with acute myocardial infarction, 3 cases died during hospitaliza?tion. Conclusions When patients present with multiple disseminated acute cerebral infarcts involving multiple arterial territories as initial manifestation, the underlying occult systemic malignancy should be considered. Hypercoagulopathy and MES might provide the clues to the diagnosis.

Objective To investigate the clinical features and TCD-detected microembolic signals in patients with hypercoagulability related multiple acute cerebral infarcts within non-single arterial territories, and to explore the possi?ble underlying mechanisms. Methods A retrospective review was conducted on all clinical, laboratory, radiological and TCD monitoring records from patients with hypercoagulability related multiple acute cerebral infarcts within non-single arterial territories, who admitted to the neurology department in our hospital. Results The data from twenty-two cases were finally included in this study. All patients presented with acute-onset localized neurological dysfunction, e.g. hemi?paresis, aphasia, hemiparesthesia, dysarthria, hemianopsia and cortical blindness. Their hypercoagulability related diseas?es included 10 cases of systemic malignancy, 5 moderate to severe hyperhomocystynemia (HCY>50μmol/L), 2 nephrot?ic syndrome, 2 antiphospholipid syndrome, 1 ulcerative colitis, 1 polycythemia vera,1 paroxysmal nocturnal hemoglobin?uria. In 18 cases, the hypercoagulability related diseases were diagnosed after their initial stroke onset. DWI showed mul?tiple disseminated acute cerebral infarcts in non-single arterial territories involving bilateral anterior or anterior plus pos?terior cerebral circulation simultaneously. Foci involved lobar cortex/subcortex of cerebral hemisphere in 22 cases, deep cerebral hemisphere in 12 cases, cerebellum foci in 10 cases,brainstem foci in 2 cases. TCD revealed microembolic sig? nals in ten of 22 patients monitored. Conclusions Patients with multiple acute cerebral infarcts involving non-single arte?rial territories, should be screened for hypercoagulability as in that hypercoagulability and microembolism might be in?volved in the etiology of cerebral infarction.

OBJECTIVETo study the absorption characteristics of alkaloids in Coptis chinensis in rat intestinal.

METHODIn situ single-pass perfused rat intestinal model was used and the concentrations of berberine and palmatine were determined by HPLC, the drug absorption rate constant (K(a)) and apparent absorption coefficient (P(app)) were tested to evaluate their absorption characteristics.

RESULTThe absorption of berberine and palmatine in different regions of rat intestinals was significantly different. From bigness to smallness, the P(app) value of berberine at 50 mg x L(-1) were ileum, duodenum, jejunum and colon, of palmatine at 50 mg x L(-1) were ileum, colon, jejunum and duodenum. The concentration of berberine and palmatine had distinctive effect on the K(a) value of berberine and palmatine were ordered from larger to little as in Wujiwan compatibility, Coptis chinensis extractive and single compound.

CONCLUSIONThe berberine and palmatine were absroped at all regions of rat intestinal. The absorption characteristics of 2 alkaloids were not passive diffusion. The other ingredients in Wujiwan compatibility and Coptis chinensis extractive could promote the absorption of alkaloids.
