Objective To investigate the effcts of cervical mild hypothermia auxiliary therapy on stress reaction in patients with cervical spinal cord injury. Methods 84 cases cervical spinal cord injury patients were randomly divided into two groups:a cervical mild hypothermia group (42 cases)and a routine treatment group (42 cases), 64 healthy men who come for health examination were recruited and served as healthy control. Routine treatment were used in both treatment groups, in edition, the LM-HAT was just applied in mild hypothermia group. The changes of the concentrations of corticotropin releasing hormone (CRH), adrenocorticotropin hormone (ACTH), corticosteroid (Cor), arginine vasopessin (AVP) in serum and the symptoms of the stress dsease(hypertension, high blood sugar)were observed before treatment and 1 week after treatment. Results The concentrations of CRH, ACTH, Cor, AVP in serum and the symptoms of stress disease in mild hypothermia group and routine treatment group were improved significantly at week after treatment(P<0.05), but the therapeutic effects of mild hypothermia group were better than that of routine treatment group (P<0.05). Conclusions The cervical mild hypothermia auxiliary therapy could significantly inhibit the secretion of stress hormones, make the H-P-A axis stable and promote the stress disease recovery.

In view of the effective traditional Chinese medicine (TCM) in the treatment of clinical depression, the mechanism is not clear, this study attempts to research the cause of depression in a complex situation to lay the foundation for the next step of TCM curative effect evaluation. Based on the brain wave of 120 depression patients and 40 ordinary person, the change regulation of acetylcholine, dopamine, norepinephrine, depression neurotransmitters and excited neurotransmitters in the whole and various encephalic regions' multi-neurotransmitters of depression patients-serotonin are analysed by search of encephalo-telex (SET) system, which lays the foundation for the diagnosis of depression. The result showed that: contrased with the normal person group, the mean value of the six neurotransmitters in depression patients group are: (1) in the whole encephalic region of depression patients group the dopamine fall (P < 0.05), and in the double centralregions, right temporal region and right parietal region distinct fall (P < 0.01); (2) in the right temporal region of depression patients group the serotonin rise (P < 0.05); (3) in the right central region, left parietal region of depression patients group the acetylcholine fall (P < 0.05), left rear temporal region fall obviously (P < 0.01). The correlation research between antagonizing pairs of neurotransmitters and neurotransmitters: (1) the three antagonizing pairs of neurotransmitters-serotonin and dopamine, acetylcholine and norepinephrine, depression neurotransmitters and excited neurotransmitters, in ordinary person group and depression patients group are characterizeed by middle or strong negative correlation. Serotonin and dopamine, which are characterized by weak negative correlation in the right rear temporal region of ordinary person group, are characterized by strong negative correlation in the other encephalic regions and the whole encephalic (ordinary person group except the right rear temporal region: the range of [r] is [0.82, 0.92], P < 0.01)/(depression patients group:the range of [r] is [0.88, 0.94], P < 0.01); acetylcholine and norepinephrine, in the whole and various encephalic region are characterized by middle negative correlation(ordinary person group:the range of [r] is [0.39, 0.76], P < 0.01 or P < 0.05)/(depression patients group: the range of [Ir] is [0.56, 0.64], P < 0.01); depression neurotransmitters and excited neurotransmitters are characterized by middle strong negative correlation (ordinary person group: the range of [r] is [0.57, 0.80], P < 0.01)/(depression patients group: the range of [r] is [0.68, 0.78], P < 0.01). (2) The two neurotransmitters which are not antagonizing pairs of neurotransmitters, serotonin and excited neurotransmitters, or acetylcholine and depression neurotra-nsmitters, or dopamine and depression neurotransmitters in the various encephalic regions are characterized by weak negative correlation. Serotonin and excited neurotransmitters are characterizeed by weak negative correlation (ordinary person group: in the right central region, left parietal region, double front temporal regions, right rear temporal region, the range of [r] is [0.25, 0.50], P < 0.01 or P < 0.05)/(depression patients group: in the whole encephalic regions, double parietal regions, double occipital regions, right front temporal region, left central region, left frontal region, the range of [r] is [0.18, 0.37], P < 0.01 or P < 0.05); acetylcholine and depression, neurotransmitters are characterized by weak negative correlation (ordinary person group: in the double frontal regions, left parietal region, left front temporal region, right rear temporal region, the range of [r] is [0.31, 0.46], P < 0.01 or P < 0.05)/(depression patients group: in double rear temporal regions, right front temporal region, double occipital regions, left central region, the range of [r] is [0.20, 0.32] , P < 0.01 or P < 0.05); do-pamine and depression neurotransmitters are characterized by weak middle negative correlation (ordinary person group: in left parietal region, right central region, left frontal region, left occipital region, double front temporal regions, the range of [r] is [0.33, 0.68], P < 0.01 or P < 0.05)/(depression patients group: in the whole region and other various regions except the left frontal region, right central region, the range of Irl is [0.21, 0.34], P < 0.01 or P < 0.05). Dopamine and acetylcholine or norepinephrine and serotonin are characterized by weak positive correlation in all encephalic regions. Dopamine and acetylcholine are characterized by weak positive correlation (ordinary person group: in left frontal region, right parietal region, left front temporal region and left rear temporal region, the range of [r] is [0.37, 0.46], P < 0.01)/(depression patients group: in the whole region and the orther various regions except the double central regions, the range of [r] is [0.23, 0.5], P < 0.01 or P < 0.05); norepinephrine and serotonin are characterized by weak positive correlation (ordinary person group: in double front temporal regions, double rear temporal regions, right frontal region and left parietal region, the range of [r] is [0.34, 0.48], P < 0.01 or P < 0.05)/(depression patients group: in the whole and various regions, the range of [r] is [0.18, 0.42], P < 0.01). The main differences between the depression patients group and ordinary person group are: (1) In the whole regin, left frontal region and right central region of depression patients group, the six neurotransmitters all fall normally (P < 0.05). (2) The percent of dopamine falling or including dopamine falling, or including dopamine falling and serotonin rising in depression patients group increases. The percent of dopamine falling or including dopamine falling in the whole region, right frontal region, right central region increases (P < 0.01), such as dopamine decreasing, serotonin increasing dopamine decreasing, serotonin increasing acetylcholine decreasing dopamine decreasing, dopamine decreasing norepinephrine increasing depression neurotransmitters decreasing, serotonin increasing acetylcholine decreasing dopamine decreasing neurotransmitters increasing and so on. (3) The percent of acetylcholine falling, or including acetylcholine falling, or including acetylcholine falling and neurotransmitters (beta)-receptor)rising in depression patients group increases. The percent of acetylcholine falling, or including acetylcholine falling in the right temporal region, double central regions increases (P < 0.05 or P < 0.01), such as acetylcholine decreasing, acetylcholine decreasing neurotransmitters increaseng, acetylcholine decreasing neurotransmitters increasing depression neurotransmitters decreasing, serotonin increasing acetylcholine decreasing dopamine decreasing neurotransmitters increasing and so on. It's showed in research that depression patients' brain are characterized by multi-neurotransmitters abnormal, the synchronous change of multi-neurotransmitters has some certain regularities, which are not the simple linear relation. It's conformed that the three antagonizing pairs, neurotransmitters-serotonin and dopamine, acetylcholine and norepinephrine, depression eurotransmitters and excited neurotransmitters of ordinary person group and depression patients group, are both characterized by strong antagonizing relation, that the two neurotransmitters which are not antagonizing pairs of neurotransmitters are characterized by weak positive correlation or negative correlation, prompt maybe has the indirect causal relationship. And the change of six neurotransmitters in depression patients' various encephalic regions is rather complex. It's conformed preliminarily that the right frontal region and right central region are characterized by dopamine decreasing, acetylcholine decreasing, serotonin increasing dopamine decreasing, serotonin increasing acetylcholine decreasing dopamine decreasing, dopamine decreasing norepinephrine increasing excited neurotransmitters decreasing, serotonin increasing acetylcholine decreasing dopamine decreasing neurotransmitters increasing, acetylchoine decreasing neurotransmitters increasing, acetylcholine decreasing neurotransmitters increasing excited neurotransmitters decreasing and so on. Contrasted with the ordinary person group, the depression patients group have the notable difference.

OBJECTIVESome research has shown that there may be memory/caution (M/C) defects in children with primary nocturnal enuresis (PNE). This study aimed to investigate whether the defects affect the intelligence level and the intelligence structure in PNE children.

METHODSIntelligence tests were performed by means of Wechsler Young Children Scales of Intelligence (C-WISC) in 40 children with PNE and 40 age-matched normal children.

RESULTSThe full intelligence quotient (FIQ), verbal IQ (VIQ) and performances IQ (PIQ) in the PNE group were in a normal range and did not different from the control group. There were significant differences in the scores for digit extent, decipher, knowledge and arithmetics between the PNE and the control groups (P < 0.05). M/C factor in the PNE group was statistically lower than in the control group (93.44 +/-11.27 vs 100.03 +/-11.79; P < 0.05).

CONCLUSIONSThe total intelligence level of children with PNE was normal, but the M/C factor in the intelligence structure had some defects, suggesting that PNE may be related to the abnormity of executive function in the frontal lobe.

The relationship between maternal nutrient intake and fetal size or infant growth was studied in 1956 pregnant women, 599 parturients and 1043 lactating women, 318 non-pregnant women included as controls. The study was conducted in eight regions that were representative of all geographical areas of China. The diet was comprised primarily of cereal products with 70% to 85% of the zinc intake derived from plant sources. Women in the third trimester of pregnancy, parturients and lactating women consumed more food than non-pregnant women or women in the first two trimesters of pregnancy. Total energy, protein and iron intakes met the recommended allowances for each stage of reproduction. Calcium and zinc intakes, however, were 50% and 47% of the amount recommended, respectively. Only 7.2% of the women exceeded two-thirds of the recommended zinc intake. The mean intake of zinc was 6.5mg to 9.0 mg each day among all the subjects. Correlation and stepwise regression analysis showed that maternal zinc intake was a predictor factor for fetal dimensions and birthweight. The results of this study show that fetal growth and birthweight are directly related to maternal zinc intake among Chinese women, and that there is no relationship between maternal zinc intake during lactation and infant height, weight, or weight gain from birth.

OBJECTIVEMethylphenidate is recommended as a first-line modality for treating attention deficit hyperactivity disorder (ADHD). In the past, immediate release methylphenidate (IR-MPH) was used for ADHD. Now oral osmotic-methylphenidate (OROS-MPH) is used for ADHD in China. This study was designed to investigate the efficacy and safety of OROS-MPH for treatment of ADHD in children.

METHODSNinety-nine children with ADHD were randomly administered with OROS-MPH (18 mg/time, once daily) and IR-MPH (5 mg/ time, twice or three times per day). After 6 weeks of treatment, the therapeutic effects were evaluated by the SNAP-IV and the IVA-CPT.

RESULTSFifty patients completed the 6-week treatment. The effective rate (83.3% vs 75%) and the complete remission rate (44% vs 25%) in the OROS-MPH treatment group were higher than that in the IR-MPH treatment group. There were statistically significant differences in the SNAP-IV and IVA-CPT scores before and after treatment in the two groups (P<0.01). The two groups had a similar incidence of side effects during treatment.

CONCLUSIONSOROS-MPH for the treatment of ADHD is effective and safe in children, and its once-daily administration is more convenient.

OBJECTIVETo study the psychologic status and their influencing factors in congenital microtia patients and their families.

METHODSTotally one hundred and two congenital microtia patients (79 men, 23 women, mean age 13.62 +/- 7.2 years) were enrolled. The patients and their families answered the questionnaire written by ourselves to identify the psychosocial problems.

RESULTS(1) 23.5% patients were found to have severe psychosocial problems, such as lack of self-confidence, close and fear and so on. (2) With the growth of age, psychosocial problems of the patients were rated high (P < 0.05). (3) For patients who found their deformations early, psychosocial problems also were rated low. (4) For patients who found their deformations by themselves, psychosocial problems also were rated low. (5) The education and psychosocial impact for parents all affected patients deeply.

CONCLUSIONSTo prevent psychosocial problems, we should operate for patients as early as possible. And correct guidance is very important for youngsters.

OBJECTIVETo study the value of the integrated visual and auditory continuous performance test (IVA-CPT) in the diagnosis of childhood attention deficit hyperactivity disorder (ADHD).

METHODSIVA-CPT was performed in 153 children (6-15 years old) with suspected ADHD. The "gold standard" for the diagnosis of ADHD was based on the Chinese Classification and Diagnostic Criteria of Mental Disease (3rd version) (CCMD-3) or the Diagnostic and Statistical Manual of Mental Disorders (4th version, USA) (DSM-IV).

RESULTSWhen CCMD-3 was used as the "gold standard", the sensitivity and specificity of IVA-CPT for the diagnosis of ADHD were 72.7% and 46.0% respectively. There were no significant differences in the diagnostic positive detection rate between the two diagnostic ways. When DSM-IV was used as the "gold standard", the sensitivity and specificity of IVA-CPT for the diagnosis of ADHD were 71.6% and 56.5% respectively. There were no significant differences in the diagnostic positive detection rate between the two diagnostic ways. There were similar results in the identification of subtypes of ADHD by the two diagnostic ways. The sensitivity and specificity of IVA-CPT for the diagnosis of ADHD in the 10-15 years old group were lower than those in the 6-9 years old group when either CCMD-3 or DSM-IV was used as the "gold standard".

CONCLUSIONSIVA-CPT can be used as an assisted tool for the diagnosis of ADHD. It is more effective for the diagnosis of ADHD in younger children.

Objective To obtain the elasticity value of solid breast lesions with supersonic shear wave elastrography (SWE) and apply the binary Logistic regression in order to evaluate the value of SWE in differential diagnosis of benign and malignant breast lesions. Methods SWE quantitative elastography was preformed in 91 breast lesions of 91 patients in Zhenghai Longsai Hospital to obtain the maximum and mean elasticity value (Emax, Emean). And receiver operating characteristic (ROC) curves were used to assess the diagnostic performance. A Logistic regression for the gray scale ultrasound and the elastic modulus was conducted with multiple variables including Emax, Emean, border, echo, form, calcification. Results Pathological examination showed 73 benign lesions and 18 malignant lesions. Emax and Emean of malignant lesions were obviously higher than those of benign lesions [(99.73±41.15) kPa vs (38.59±14.28) kPa, (61.45±24.88) kPa vs (23.46±11.44) kPa, t=-15.05,-14.12, both P=0.000]. The area under the ROC curve of Emax and Emean were 0.932 and 0.915. Taking 63.70 kPa as the threshold of Emax, the sensitivity was 77.8%and the speciifcity was 97.3%. Then taking 44.22 kPa as the threshold of Emean, the sensitivity was 83.3%and the speciifcity was 94.5%. The results of Logistic regression analysis showed:the 3 most effective variables were Emax, border of the lesions and Emean. Conclusions The multivariate analysis model of binary Logistic regression can select the valuable indexes of differential diagnosis of benign and malignant breast lesions. SWE plays an important role in differentiating benign and malignant lesions and it is valuable in clinical practice.

The cis and trans isomers separation of 2-butene-1,4-diol and lafutidine were studied by HPLC on two kinds of chiral columns: (S,S)-Whelk-O 1 and ChiraSpher. The isomers of 2-butene-1,4-diol can be separated on both chiral columns while the isomers of lafutidine can only be resolved on ChiraSpher column. The influence of different type and amount of mobile phase modifier on the isomers separation was extensively studied. The resolution of cis and trans isomers of 2-butene-1,4-diol was 2.61 on (S,S)-Whelk-O 1 column with hexane-ethanol (97:3, v/v) as the mobile phase. The resolution of lafutidine was 1.89 on ChiraSpher column with hexane-ethanol-THF-diethylamine (92:3:5:0.1, v/v/v/v) as the mobile phase. LC-MS methods were developed to identify the isomer peaks.
