OBJECTIVETo evaluate the therapeutic effect of Longjintonglin Capsules on type IIIA prostatitis accompanied by abnormal semen liquefaction.
METHODSWe selected 140 patients with type IIIA prostatitis accompanied by abnormal semen liquefaction according to the diagnostic standards of the American Institutes of Health (NIH) and treated them with Longjintonglin Capsules orally 3 capsules once tid for 12 weeks. We obtained the NIH Chronic Prostatitis Symptom Indexes (NIH-CPSI), traditional Chinese medicine (TCM) syndrome scores, leukocyte count in the expressed prostatic secretion (EPS), semen liquefaction time, and the results of semen analysis and compared these indicators before and after the treatment.
RESULTSOf the 140 cases, 132 were included in this study, excluding 8 due to their incomplete case histories. Before and after 4, 8 and 12 weeks of medication, the total NIH-CPSI scores were 24.52 ± 5.43, 21.28 ± 4.85, 18.01 ± 4.28, and 14.49 ± 3.65 (P < 0.01), the TCM syndrome scores were 35.63 ± 6.07, 26.66 ± 5.03, 17.37 ± 4.18, and 11.11 ± 3.96 (P < 0.01), and the leukocyte counts (/HP) were 27.50 ± 7.01, 22.38 ± 5.22, 16:76 ± 4.10, and 11.40 ± 4.74 (P < 0.01), respectively. After 12 weeks of treatment, 31 of the patients with type IIIA prostatitis were cured and another 72 well responded, with an overall response rate of 78.0%. Of those with abnormal semen liquefaction, 61 were cured, 39 well responded, and 32 failed to respond, with an overall effectiveness rate of 75.8%. Semen analysis showed significantly increased percentage of progressively motile sperm after 4, 8 and 12 weeks of medication as compared with the baseline (P < 0.01). No abnormal liver or renal function or other adverse reactions were observed during the treatment.
CONCLUSIONLongjintonglin Capsules, with its advantages of safety, effectiveness and no obvious adverse effects, deserve to be recommended for the treatment of type IIIA prostatitis accompanied by abnormal semen liquefaction.

Background:Reports on the aquaporin-4 immunoglobulin G (AQP4-IgG) status for cognitive performance
and neuroimaging correlations are limited in neuromyelitis optica (NMO) and multiple sclerosis (MS)
literature. Methods: Cognitive results of 19 MS and 15 NMO patients were compared with 47 agematched
controls. Apparent diffusion coeffi cient (ADC) values were used to delineate gray matter
and white matter damages and correlate with neuropsychological results. Results: Verbal memory test
showed signifi cant differences between MS and NMO in the late registration, early and delay recall
(p<0.05), while their retention rates were even. In MS, ADC values were signifi cantly elevated in the
dorsolateral prefrontal and occipital gray matter which was in contrast with NMO group that showed
elevation in the dorsolateral prefrontal gray matter and parieto-occcipital white matter. AQP4-IgG
status exerted a limited effect on ADC values and neuropsychological results.
Conclusions: Verbal memory test might be helpful in differentiating NMO and MS. ADC values
can be used as a surrogate marker for tissue injury in NMO and MS since they were in line with the
cognition scores. Anatomical regions with elevated ADC values were different in NMO and MS.

OBJECTIVETo investigate the influences of ultrafiltration and alcohol sedimentation on protective effects of Radix Astragali and Radix Hedyseri against rat's cerebral ischemia.
METHODSUsing dexamethasone (im.) and ligating common carotid artery, the rat stasis model combined transient cerebral ischemia was established to evaluate the effects of the ultrafiltration and alcohol sedimentation through detecting antioxidant system and other indexes in brain tissue.
RESULTSThe results showed that the 6 g/kg water extract(crude drug), ultrafiltration and alcohol sedimentation of Radix Astragali and Radix Hedyseri could upgrade adenosine-triphosphate (ATP), superoxide dismutase (SOD) and catalase (CAT), and degrade malondialdehyde(MDA) and water content of brain tissue in rat stasis model combined transient cerebral ischemia, the water extract and ultrafiltration of them could degrade lactic acid (LD) of brain tissue, and the effects of alcohol sedimentation of Radix Astragali and Radix Hedyseri become weaker than water extract of them.
CONCLUSIONThe water extract, ultrafiltration and alcohol sedimentation of Radix Astragali and Radix Hedyseri have some protective effects on cerebral ischemia in rats, the effective differences of the extract through the same extraction method are not remarkable, and alcohol precipitation method has obvious influences effect on Radix Astragali and Radix Hedyseri.

Surface molecularly imprinted polymers (SMIPs) for selective adsorption of ampicillin sodium were synthesized using surface molecular imprinting technique with silica gel as a support. The physical and morphological characteristics of the polymers were investigated by scanning electron microscope (SEM), Fourier transform infrared spectroscopy (FT-IR), thermogravimetric analysis (TGA), elemental analysis and nitrogen adsorption–desorption test. The obtained results showed that the SMIPs displayed great adsorption capacity (13.5μg/mg), high recognition ability (the imprinted factor is 3.2) and good binding kinetics for ampicillin sodium. Finally, as solid phase extraction adsorbents, the SMIPs coupled with HPLC method were validated and applied for the enrichment, purification and determination of ampicillin sodium in real milk and blood samples. The averages of spiked accuracy ranged from 92.1%to 107.6%. The relative standard deviations of intra-and inter-day precisions were less than 4.6%. This study provides a new and promising method for enriching, extracting and determining ampicillin sodium in complex biological samples.
