Objective:To explore the clinical presentations and symptom distribution in adults with attention-deficit/hyperactivity disorder(ADHD) among non-alcohol substance use disorder population,and to prove the effectiveness of adult ADHD diagnosis.Methods:Thirty adults with ADHD and thirty non-ADHD controls were selected from Beijing Compulsory Detoxification Center,matched with sex,age,and education.Data collection included the following:(1)Self-report measures of developmental history,employment history,social history and ADHD clinical symptoms.(2)Psychiatric interview using structured assessments included the Clinical Diagonsitic Interview Scale(CDIS)for Diagnostic and Statistical Manual of Mental Disorders(DSM-IV).(3)Evaluation for cognitive function with the Wechsler Adult Intelligence Scale-Revised Chinese(WAIS-RC).Results:(1)The clinical core symptoms(such as attention deficit,restlessness,and impulsive symptoms)among adulthood ADHD were similar to childhood ADHD except for some hyperactivity symptoms.(2)The symptoms of attention deficit,restlessness and impulsiveness were more frequently in both of adulthood and childhood ADHD than non-ADHD controls(P

Objective To evaluate the job burnout of the nurses in sterile laminar flow wards and offer proposals for improvements.Methods Forty nurses in sterile laminar flow wards were surveyed with MBI-GS.Results The scores of emotional exhaustion,cynicism,job inefficiency were higher after working in sterile laminar flow wards for 3 months than those working in general wards for 3 months.Conclusions The nurses in laminar flow wards are prone to have job burnout.Standardized training,humanized management and positive psvchological intervention can improve the job burnout of the nurses in laminar flow wards.

The difference between absorption of unfractionated heparin (UFH) and low molecular weight heparin (LMWH) after oral and oral cavity administration were studied respectively, and the compatible enhancer for oral cavity delivery system of both drugs was found. The LMWH and UFH films were prepared with two bioadhesive materials Carbopol and alginate sodium for oral cavity delivery. The activated partial thromboplastin time (APTT) was used to determine LMWH and UFH in plasma after oral, oral cavity and sc administration in rats. The results show that the enhancer (Labrasol) can increase the absorption of LMWH and UFH through oral cavity in rats but not obviously. The oral cavity iontophoretic delivery system is a useful method to improve the absorption of LMWH and UFH through oral cavity mucosa.

Objective To test the utility of a new type of inflatable rehabilitation boot in the treatment of Danis-Weber type-A stable external malleolus fractures. Methods Fifty-four patients with stable external malleolus fractures were randomized into two groups. After closed reduction, the observation group was treated by immobilisation with the inflatable rehabilitation boot and the control group with a plaster slab. All were instructed to avoid weight-bearing on the affected side. The swelling volume of the injured limb was measured by drainage measurement before treatment and at the 1st, 3rd and 7th days after treatment. Pain was evaluated using a visual analogue scale (VAS) score before treatment and after 12, 24 and 72 hours. All of the ankles were x-rayed to recheck for displacement after 2weeks. Results The average volume of the injured limbs in the observation group was significantly less than in the control group at every time point. The average VAS score in the observation group was significantly lower than that in the control group. Fracture displacement in the observation group was also significantly better. Conclusions The inflatable rehabilitation boot has better curative efficacy than the typical plaster slab for patients with stable external malleolus fractures in terms of improving edema in the injured limb, relieving pain and preventing fracture displacement.

Objective To investigate the characteristics of apparent diffusion coefficient (ADC)values in the normal fetal kidney and to explore the normal data reference of fetal kidney by using diffusion-weighted imaging (DWI).Methods 71 normal kidneys of fetuses confirmed by ultrasound and MR were examined with DWI with four b values of 100 s/mm2 ,200 s/mm2 ,500 s/mm2 and 700 s/mm2 ADC values of the symmetrical ROIs were compared between left and right kidney for each b value.While ADC values between different group in ipsilateral kidney were compared between different b values.And the relationship between ADC values and gestational age was also evaluated.Results When b = 100 s/mm2 ,there was a statistically significant difference between the ADC value of left and right kidney,and the remaining group showed no statistically significant differences between the ADC values of left and right kidney.Comparisons among different b values of ipsilateral kidney showed statistically significant differences among the groups with different b values except the comparison between b=100 s/mm2 and b=700 s/mm2 groups of the right kidney with the increase of gestational weeks,the ADC values of bilateral kidneys were declining,and there was a reflection of this trend in different b values. Conclusion It is feasible for using DWI to evaluate the fetal kidney development.With a selected different b value,ADC value is a specific quantitative parameter that could help evaluating normal fetal kidney development.

BACKGROUND:So far steroid pulse therapy andsurgical decompressionarethe main accepted therapiesfor spinal cord injury, but these methods make no effects on injured neurons. Nerve growth factors and endogenous neural stem cels play a role in theneuronalregeneration and remyelination, which provides a newidea for spinal cord injury treatment.
OBJECTIVE:To explore the effect of the basic fibroblast growth factor on proliferation of endogenous neural stem cels after spinal cord injury and to analyze its relationship with the increased fluoro-gold labeled neurons.
METHODS:Totaly 48 Kunming mice were randomly divided into four groups including normal, spinal cord injury, treatment and sham operation groups. Acute spinal cord injury models were establishedin the spinal cord injury and treatment groups, andthe normal group was subjected to operationthat did not damage the spinal cord. At 2hoursafter regaining consciousness, the treatment group was givendailyinjection of MTPBS containing 25 μg/kg basic fibroblast growth factors and 1% album. And at 7 days, laminectomy was carried out again at the L1segment in the former three groups and a smal piece of sterile gelfoam soaked with fluoro-gold was inserted into the incision. The sham operation group was given no processing. Afterwards, mouse motor behavior was assessed using Rotarod and Platform Hang tests; neurons in the corticospinal and rubrospinal tracts were labeled with fluoro-gold; the number of endogenous neural stem cels positive for nestin was detected by immunohistochemistry method. Besides, the correlation betweenthe number offluoro-gold labeled neurons andthe number ofendogenous neural stem cels was assessed.
RESULTS AND CONCLUSION:The basic fibroblast growth factor could significantly improve the mouse motor behavior after spinal cordinjury. And the number of endogenous neural stem cels was significantly increased after the basic fibroblast growth factor injection, which was related to the increased fluoro-gold labeled neurons.In conclusion, basic fibroblast growth factors play an important role in the proliferation of endogenous neural stem cels after spinal cord injury. Furthermore, endogenous neural stem cels improve locomotive behaviors by encouraging the neuronalproliferation.

OBJECTIVE:To observe the efficacy of capecitabine combined with cisplatin in the treatment of advanced gastric cancer and its effect on invasion and metastasis of gastric cancer. METHODS:94 patients with advanced gastric cancer were ran-domly divided into control group(47 cases)and observation group(47 cases). Control group received 65-75 mg/m2 Docetaxel injec-tion,d1,continuous intravenous infusion of 2 h+15-20 mg/m2 Cisplatin for injection,d1-5,continuous intravenous infusion of 2 h in the dark. Observation group received 1 000 mg/m2 Capecitabine tablet,orally,twice a day+Cisplatin for injection(the same us-age and dosage with control group). 3-week was regarded as a treatment course,and it lasted 3 courses. Clinical efficacy,matrix metalloproteinase-2(MMP-2)and MMP-9 levels were observed,6 and 12 months survival rate and incidence of adverse reactions were followed-up. RESULTS:There was no significant difference in the total effective rate in 2 groups(P>0.05). Grade 1-2 liver dysfunction,thrombocytopenia,and the incidence of nausea and vomiting in observation group were significantly lower than con-trol group,6 and 12 months survival rates were significantly higher than control group,the differences were statistically significant (P<0.05). Before treatment,There was no significant difference in MMP-2 and MMP-9 levels in 2 groups(P>0.05). After treat-ment,MMP-2 and MMP-9 levels in 2 groups were significantly lower than before,and observation group was lower than control group,the differences were statistically significant(P<0.05). CONCLUSIONS:The efficacy of capecitabine combined with cispla-tin is similar to docetaxel combined with cisplatin in the treatment of advanced gastric cancer,but docetaxel combined with cisplat-in is superior in terms of reducing MMP-2 and MMP-9 and safety.
