It is the objective of this study to develop dynamic predictive model for the extraction process of red Ginseng using NIR spectroscopy. NIR spectroscopy was collected online and PLSR models were developed for total quantity of ginsenosides. The performance of NIR prediction model achieved R, RMSEC, RMSEP of 0.996 09, 0.018 9, 0.016 8, respectively. A first order dynamic mass transfer model was combined with NIR prediction of the quality indicator to predict the trajectory of the extraction process based upon the initial 3 or 4 data points. The results showed good agreement with actual measurements indicating reasonable accuracy of the predictive model. It could potentially be used for advanced predictive control of the extraction process.

OBJECTIVETo explore the molecular mechanism of pain associated with chronic prostatitis and chronic pelvic pain syndrome (CP/CPPS) in the rat model of prostatic inflammation.

METHODSThirty-six male SD rats were equally randomized to an experimental and a control group, the former injected with 50 μl of 3% λ-carrageenan into the ventral prostate to make the model of non-bacterial prostatic inflammation, while the latter with the same volume of sterile saline solution. At 1, 2 and 4 weeks after modeling, the prostate, L6-S1 dorsal root ganglion (DRG) and spinal cord were harvested for examination of the expressions of the nerve growth factor (NGF), transient receptor potential ankyrin 1 (TRPA1), and calcitonin-gene-related peptide (CGRP) by immunohistochemistry and Western blot.

RESULTSThe expressions of NGF, TRPA1 and CGRP in the prostatic tissue were all significantly increased in the experimental group as compared with the control (P <0.05), with a gradual decrease with the prolonging of time (P <0.05). In the L6-S1 DRG and spinal cord, the expressions of NGF, TRPA1 and CGRP exhibited no significant differences between the experimental and control groups at 1 week after modeling (P >0.05) and kept at high levels in the experimental group at 2 and 4 weeks, though not significantly different from those at 1 week (P >0.05). Statistically significant differences were observed in the expressions of the three proteins in the experimental rats among different time points (P <0.05), but not between the two groups at any time point (P >0.05).

CONCLUSIONThe molecular mechanism of CP/CPPS can be evaluated in the rat model of prostatic inflammation established by injecting λ-carrageenan into the prostate. TRPA1 may play an important role in connecting the upstream and down-stream pathways of CP/CPPS-associated pain.

Objective To investigate the effects of single dose of dexmedetomidine and fentynyl on treatment of emergence agitation in adult patients after general anesthesia.Methods Sixty patients suffering from emergence agitation after general anesthesia were divided into two groups randomly(n=30 each):dexmedetomidine group (group D)and fentaynl group (group F).Patients in group D received dexmedetomidine at a dose of 0.5μg/kg,and those in group F received fentanyl at a dose of 1μg/kg respectively.If patients still agitate after above treatment,intermission infusion of propofol at bolus of 1.0 mg/kg was used for further treatment till patients attain peaceful state.Results Twen-ty-nine paients in group D had no agitation,only one patient had mild agitation after administration of dexmedetomidine,while four patients had severe agitation,four patients had moderate agitation and 9 patients had mild agitation after administration of fentanyl(P<0.05);the time from first treatment to no agitation in group D was (11±3)min,shorter than that in group F (27±9)min (P<0.05);the dose of propofol used in group D was (50±0)mg,less than accumulative doses of propofol in group F (270±40)mg (P<0.05);21 (70%)patients in group D had radycardia and 9 (30%)patients in group F had respiratory depression(P<0.05).Conclusion Intravenous dexmedetomidine at a dose of 0.5 μg/kg attainted was effective in treating emergence agitation in adult patients after general anes-thesia as compared with fentanyl.

Objective To investigate the correlation between FA value,ADC value and limb muscle strength score measured by magnetic resonance imaging in patients with ischemic stroke,aims to to analyze the clinical value of magnetic resonance imaging in limb muscle strength.Methods Twenty patients with acute cerebral infarction and treated from June 2015 to Junly 2016 were recruited from This hospital,and the simplified Fugl-Meyer motor function score was observed for all patients within 3 days.Tensor imaging examination was conducted to observe the distribution of nerve fiber bundles,FA value,ADC value changes.Results The FA value and ADC value of the infarct side were significantly different from those of the contralateral side(t=8.70,t=-18.70,P＜0.05);There were significant differences in FA value and ADC value between the infarcted ventricle hind limbs and the contralateral side of the infarcted ventricle(t=-5.16,t=-5.08,P＜0.05).The FA value of the infarcted ventral hind limbs had positive correlation with the simplified Fugl-Meyer motor function score(R=0.863,P=0.013).Conclusion FA value and ADC value of acute infarct and internal hindlimb are lower than FA value and ADC value of contralateral normal white matter.The FA value of internal capsule hind limbs is closely related to the simplified Fugl-Meyer motor function score.

Objective To evaluate the incidence of four aberrant behaviors in patients with pervasive developmental disorders (PDDs).Methods The abnormal behaviors during the last month in 138 PDDs patients were assessed with Aberrant Behavior Checklist and Conners Index of Hyperactivity.Results The incidence of aberrant behaviors was 61.6％ for hyperactivity,81.9％ for stereotyped behaviors,13.77％ for self-injury,and 58.70％ for irritability in PDDs patients.The occurance of irritability in autism patients was higher than that of asperger syndrome (AS) patients (x2 =5.623,P=0.018).Conclusion Stereotyped behaviors,hyperactivity and irritability are common in children with PDDs.Autism patients are more likely to exhibit irritability behaviors than AS patients.

Objective To investigate the influence of hyperactivity, Stereotyped behaviors , self-injury and irritabili?ty on parenting stress and emotions of the caregivers for patients with pervasive developmental disorders (PDDs). Methods Abnormal behaviors during last month were assessed in 138 PDDs patients by using Aberrant Behavior Checklist (ABC) and Conners Index of Hyperactivity (CIH). The parenting stress and the emotional state of the patients’parents were evalu?ated by the Caregiver Strain Questionnaire (CGSQ) and Hospital Anxiety and Depression Scale (HAD), respectively. Re?sults Anxiety, depression and combination of anxiety and depression were present in 6.2%, 17.8%and 29.5%of PDDs caregivers, respectively. The partial correlation analysis showed that CGSQ score of patients’parents positively correlated with CIH score (r=0.201, P=0.023) and stereotyped act (r=0.189, P=0.033) of the patients, and negatively correlated with stereotyped speech (r=-0.219, P=0.013). The anxious mood of parents positively correlated with stereotyped act (r=0.206, P=0.021). Conclusions Anxiety and depression are common in caregivers of PDDs. Except for stereotyped speech, aber?rant behaviors of the PDDs increase parenting stress and worsen anxious mood of caregivers.
