An S-naproxen (S-NAP) molecularly imprinted monolithic stationary phase (MIMSP) with specific recognition for S-NAP and naproxen (NAP) was prepared by in situ technique,utilizing 4-vinylpridine (4-VP) as a function monomer,ethylene glycol dimethacrylate (EDMA) as a cross-linking agent,and low-polar solvents (toluene and dodecanol) as porogenic solvents.The selectivity of the polymers for S-NAP and NAP was evaluated by high performance liquid chromatography (HPLC).The binding characteristics were tested by Scatchard analysis.Racemic NAP could be specifically separated to some extent.At the same time,NAP could be separated from ibuprofen under optimized conditions.Scatchard analysis showed that two classes of binding sites existed in the S-NAP-imprinted polymers,with their dissociation constants estimated to be 1.045 and 5.496 μM,respectively.The results demonstrate that S-NAP and NAP can be recognized specifically on the obtained MIMSP.

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.

Objective:
To analyze the consistency between self-reported oral health and proposed standard in evaluating children oral health status, and to test whether self-reported oral health can be used in children population.
Methods:
The clinical examination data and questionnaire data were 2 158 children aged 12-year-old in Beijing, China. Child oral health status was measured by self-reported oral health and proposed standard from World Health Organization (WHO), and was classified into "good, general, poor" based on each method. Kappa test was used to evaluate the consistency of two measurements. Using multivariate nonordinal logistic regression to identify the influencing factors of self-reported oral health, and to explore the possible reasons for the consistency differences of two measurements.
Results:
According to the WHO standard, 25.5%, 65.3% and 9.2% children oral health were rated as good, general and poor, respectively. The proportion was 50.6%, 37.7% and 11.8% respectively based on self-report method. Kappa value for two measurements was 0.04, indicating poor agreement between two methods. Results from regression model show that both the untreated caries (OR=2.47, P<0.01) and toothache (OR=3.54, P<0.01) were associated with self-reported oral health, while not observed in periodontal health (OR=1.34, P=0.18) and oral hygiene status(OR=0.95, P=0.75).
Conclusion
Self-reported oral health results can reflect caries status to some extents among children, but it failed to reflect other aspects, such as periodontal health status and oral hygiene. Self-reported oral health among children should be considered based on the requirements of assessment content and accuracy in the future work.
