AIM To study the effect of azone on transdermal absorption of 6-gingerol.METHODS In vitro transdermal diffusion test was performed by TP-6 horizontal diffusion pool.In vitro rat skins were selected as permeation barrier,the effects of different concentrations of ethanol and azone on permeation performance of 6-gingerol were investigated.RESULTS Both 30％ ethanol and 3％ azone contributed to the significant permeation enhancement of 6-gingerol.CONCLUSION This research can provide reference for the preparation of transdermal drug delivery systems containing 6-gingerol.

INTRODUCTIONThis study aimed to determine the early growth patterns of preterm infants who required prolonged hospitalisation in terms of body weight Z-score, and to explore the influencing factors and predictors of their growth.

METHODSThe criteria of enrolment included preterm birth, singleton pregnancy, hospitalisation within the first 24 hours of life, hospital stay ≥ 28 days and clinical follow-up beyond 91 days of corrected age. Body weight Z-scores and the incidence of underweight infants were reviewed periodically, and the influencing factors and possible predictors of growth analysed.

RESULTSBody weight Z-scores of all infants of gestational age (GA) groups kept decreasing, with a trough seen at 36 weeks corrected gestational age (CGA). At corrected full-term, body weight Z-scores for all birth weight groups achieved birth level and were higher than that at 36 weeks CGA. Body weight Z-scores at 61 days corrected age was (-0.300 × GA [weeks] + 0.210 × birth weight [g] + 0.682 × body weight Z-score) at 40 weeks CGA. The cut-off values for body weight Z-score at birth (cut-off, -1.79; sensitivity, 100%; specificity, 91.3%) and 61 days corrected age (cut-off, -1.95; sensitivity, 100%; specificity, 97.1%) were selected to predict the risk of being underweight at 183 days corrected age.

CONCLUSIONEarly growth restriction is a practical problem in preterm infants with prolonged hospitalisation. Body weight Z-scores at 40 weeks CGA and 61 days corrected age can be used to predict body weight gain prior to 183 days corrected age in these infants.

OBJECTIVETo compare the therapeutic effects of peripheral facial paralysis in acute stage by different interventions and explore the better treatments of peripheral facial paralysis.

METHODSOne hundred and thirty one cases of Bell's facial paralysis were randomly divided into three groups. In acupuncture group (44 cases), Dicang (ST 4), Jiache (ST 6), Hegu (LI 4), Yangbai (GB 14) and Taiyang (EX-HN 5), etc. were applied; in electroacupuncture group (45 cases), the selection of acupoints and needling method were same as those in acupuncture group, and the electroacupuncture therapy was applied on Dicang (ST 4), Xiaguan (ST 7), Yangbai (GB 14) and Taiyang (EX-HN 5) in acute stage; in medication and acupuncture group (42 cases), Prednisone and Acyclovir were taken by oral administration, Vitamin B1 and Vitamin B12, were applied by intramuscular injection in acute stage, and acupuncture was applied by the way which was same as that in acupuncture group during quiescent and recovery stages. The curative effects were evaluated by House-Brackmann Grading Scale, and the failed rates were observed by follow-up after one and three months.

RESULTSThe cured and markedly effective rates were 79.6% (35/44), 93.4% (42/45) and 78.6% (33/42) respectively in acupuncture group, electroacupuncture group and medication and acupuncture group, and the result in electroacupuncture group was superior to those in acupuncture group and medication and acupuncture group (P < 0.05). The cured rates above tympanichord were 54.2% (13/24), 85.2% (23/27) and 48.0% (12/25) in acupuncture group, electroacupuncture group and medication and acupuncture group, and the result in electroacupuncture group was superior to those in acupuncture group and medication and acupuncture group (P < 0.01). There was no significant differences of cured rates below tympanichord among three groups (P > 0.05); and the failed rate in electroacupuncture group was much lower than those in acupuncture group and medication and acupuncture group by follow-up after one and three months (all P < 0.01).

CONCLUSIONThe peripheral facial paralysis is effectively treated by electroacupuncture in acute stage, and it suggests that electroacupuncture should be applied early during the acupuncture treatment of peripheral facial paralysis.

BACKGROUNDPrior research about N400 has been mainly based on English stimuli, while the cognitive processing of Chinese characters is still unclear. The aim of the present study was to further investigate the semantic processing of Chinese idioms.

METHODSEvent related potentials (ERP) component N400 was elicited by 38 pairs of matching (congruent) and mismatching (incongruent) ended Chinese idioms: ending words with same phoneme but different shape and meaning (sPdSdM), with similar shape but different phoneme and meaning (sSdPdM), with same meaning but different phoneme and shape (sMdPdS), and words with different phoneme, shape and meaning (dPdSdM) and recorded by Guangzhou Runjie WJ-1 ERP instruments. In 62 right-handed healthy adults (age 19 - 50 years), N400 amplitudes and latencies were compared between matching and mismatching conditions at Fz, Cz and Pz.

RESULTSN400 showed a midline distribution and could be elicited in electrodes Fz, Cz and Pz. The mean values of N400 latencies and amplitudes were obtained for matching and mismatching ending words in healthy adults. Significant differences were found in N400 latencies and amplitudes in matching and mismatching ending-words idioms in healthy adults (P < 0.05). Compared with matching ending-words idioms, N400 latencies were prolonged and the amplitudes were increased in mismatching ones. N400s elicited by different types of stimuli showed different latencies and amplitudes, and longest N400 latency and largest N400 amplitude were elicited by ending-words with dPdSdM. No gender difference was found of N400 latency and amplitude in this study (P > 0.05).

CONCLUSIONSCompared with English stimuli, Chinese ideographic words could provide more flexible stimuli for N400 research in that the words have 3-dimension changes - phoneme, shape and meaning. Features of N400 elicited by matching and mismatching ending words in Chinese idioms are mainly determined by the meaning of the word. Some issues of N400 elicited by Chinese characters deserve further research.

OBJECTIVESTo investigate the incidence of intra- and extrauterine growth retardation (EUGR) and growth restriction in premature infants, and to illustrate the growth pattern of them in postnatal and infantile period.

METHODSAll premature infants were admitted to our neonatal intensive care unit (NICU) during the recent 7 years. The criteria for enrollment were (1) gestational age < 37 weeks; (2) single fetus; (3) admitted within the first 24 hours of life; (4) hospitalization period ≥ 14 days; (5) clinical follow-up persisted till ≥ 3 months of corrected gestational age. Intrauterine growth restriction (IUGR), EUGR and growth restriction were defined as having a measured growth value (weight) that was ≤ 10(th) percentile of Chinese infants' growth curve in corrected age on admission, discharge and follow-up period. Results were analyzed by using SPSS 12.0 statistical software package by chi-square test, rank-sum test, and t test.

RESULTSTwo hundred and thirty nine infants were involved, 134 were boys and 105 girls. The incidence of IUGR and EUGR assessed by weight was 25.5% and 40.6%, respectively. The lower the birth weight was, the higher the incidence of IUGR and EUGR was. The percentile of body weight in the growth curve at discharge was lower than that at birth (Z = -7.784, P = 0.000). The incidence of growth restriction assessed by weight was 20.5%, 15.0%, 8.8%, 17.0%, 10.4%, 10.1%, 11.9%, 7.0% at corrected gestational age of 38 - 40 weeks, corrected age of 28 d, 61 d, 91 d, 122 d, 152 d, 183 d, and 274 d, respectively. The incidences of growth restriction were stable when the corrected age was older than 91 days. The incidence of growth restriction in female premature infants at 183 days' corrected age was higher than that in male children (χ(2) = 6.181, P = 0.017), the incidence was 19.3% and 3.8% respectively. During the follow-up period, most of the average body weight of premature infants whose gestational age was < 32 weeks or birth weight ≤ 1500 g were lower than the 50(th) percentile of the growth curve except the average body weight of boys whose gestational age < 32 weeks at corrected age of 2 and 4 months.

CONCLUSIONSPremature and/or low birth weight infants are at high risk of growth restriction, especially very low birth weight infants. The incidence of growth restriction decreased with growth. Long-term prognosis requires further investigation.

Objective To observe the curative effect of Shuxuetong injection on intracerebral hemorrhage at acute phase. Methods Sixty patients with intracerebral hemorrhage at acute phase were randomly divided into treatment group and control group (n=30). The treatment group intravenously received 6 mL Shuxuetong daily for 15 consecutive d and control group was treated with routine treatment. CT was performed to evaluate the volumes of hematomas, the changes of low-density areas surrounding the hematomas on the 1st, 7th and 15th d of treatment, respectively. The neurologic impairment evaluation scores were recorded with National Institutes of Health Stroke Scale (NIHSS). Monitor on plasma fibrinogen level was performed in both groups. Results No significant differences on the volumes ofhematomas, low-density areas surrounding the hematomas, neurologic impairment evaluation scores, and plasma fibrinogen level were noted between the 2 groups on the admission day (P＞0.05). On the 7th and 15th d of treatment, volumes of hematomas, low-density areas surrounding the hematomas and neurologic impairment evaluation scores in the treatment group reduced significantly as compared with those in the control group (P＜0.05), however, plasma fibrinogen level was not statistically different between the 2 groups (P＞0.05). Conclusion Shuxuetong injection is superior to routine treatment in reduction of volumes of hematomas, low-density areas surrounding the hematomas, neurologic impairment evaluation scores, but not in reduction of plasma fibrinogen level.
