Objective To figure out changes of serum excitatory amino acids (EAAs) levels in patients with amnestic mild cognitive impairment (aMCI) and Alzheimer's disease (AD).Methods The levels of serum EAAs was assessed in 34 cognitively normal control subjects,30 patients with aMCI,and 32 patients with AD using high performance liquid chromatography (HPLC).Results ①Higher serum concentrations of glutamate((39.6?22.1) ?mol/L),alanine((282.5?71.3) ?mol/L) were found in the aMCI patients (P=0.044,P=0.007),and higher serum concentrations of glutamate ((42.2?21.8) ?mol/L),glycine ((464.2?142.6) ?moL/L) were found in the AD patients than in the control subjects (P=0.010,P=0.010).②No statistically significant difference of EAAs level between the aMCI and AD groups was found.③A close and positive correlation between the serum concentrations of glutamate, aspartate and the mini-mental status examination scores were found in AD patients:the 2 amino acid levels were higher in patients with mild dementia((42.1?21.3),(55.0?29.0) ?mol/L) than those with moderate or severe dementia ((25.4?9.2) ?mol/L,P=0.023;(34.6?11.1) ?mol/L,P=0.036). Conclusion EAAs,correlating with the severity of the condition,play a significant role in AD,while aMCI patients also have disturbance of metabolism of EAAs,indicating that it has similar pathogenesis to AD.

OBJECTIVETo study the effect of the technique of synchronously perforating and transplanting hair follicular-units in the treatment of cicatricial alopecia after burn.

METHODSOne hundred and sixty-six patients with 217 bald scar areas after burn were treated with above-mentioned technique from January 2002 to April 2008. Scalp strips, with conforming the necessity for grafting, were harvested from the occipital or temporal region. A series of follicular-units, each composing 1 - 3 hairs, were dissected from the strips under microscope or magnifying glass. Size-matching micro-slots were made in the scarred recipient area with 16 - 20 G needles to accept the grafts. The prepared follicular-unit was synchronously implanted into the bottom of the micro-slot as the needle being withdrawn. Patients who were not satisfactory with the density of hairs after I stage surgery underwent II stage surgery a half year later. Ten recipient areas with clear boundary in 10 patients were optionally chosen to observe the density of follicular-units and hair amount with naked eyes after I stage surgery. Survived transplanted hairs in above-mentioned 10 areas were counted to calculate hair survival rate at follow-up. Patients' postoperative satisfaction ratings were surveyed with questionnaire.

RESULTSIn one half of the patients, treatment was finished after I stage surgery, the other one half received 2 stages of surgery. The follicular-unit density reached 15 - 25 grafts/cm(2) with 40 - 70 hairs/cm(2) after I stage surgery. All patients were followed up for over 8 months. Grafted hairs grew well in a natural way. 96.5% mean hair survival rate was observed in the 10 recipient areas. From patients who received only I stage surgery, 61 patients (73.5%) were very satisfactory and 22 patients (26.5%) satisfactory with the results. From the other half of patients, 76 patients (91.6%) were very satisfactory and 7 patients (8.4%) satisfactory with the results.

CONCLUSIONSThe technique of perforating and transplanting follicular-unit hair synchronously is safe and effective with less surgery-induced injury and less bleeding. Hairs transplanted on cicatricial alopecia area with this technique grow well with high survival rate.

OBJECTIVETo study the therapeutic effects and its mechanism of combination of hemofiltration (HF) and peritoneal dialysis (PD) in the treatment of severe acute pancreatitis (SAP).

METHODSForty patients with SAP were divided at random into the HF + PD group (therapeutic group, 25 patients) and the non-HF + PD group (contrast group, 15 patients). Both groups were treated by the conventional mode of therapy. The release time of abdominal pain and distention, CT scores, APACHE II scores, the time of hospital stay, cost of treatment in hospital, operative rate and rate of complications and recovered rate of the two groups were compared. Simultaneously, the concentration of serum and fluid filtrated pro-inflammatory cytokines TNF, IL-6 and IL-8 were also determined pro and post the therapy.

RESULTSThe time needed for the disappearance of abdominal pain and the amelioration of abdominal distension, CT scores, APACHE II scores, the average hospital stay and hospital cost of the therapeutic group were significantly decreased compared with those of the contrast group. The cytokines detected at the end of 1d, 2d after HF + PD were decreased significantly compared with those observed in pro HF + PD and the contrast group.

CONCLUSIONSThe above results show that the cytokines overproduced during the development of SAP can be removed effectively from the circulation and the fluid filtrated by means of HF + PD. The continual deterioration of the local focus and systemtic presentation could be prevented effectively too, and the earlier the treatment of HF + PD, the better the prognosis.

OBJECTIVE: To study the clinical features of vasovagal syncope (VVS) and postural orthostatic tachycardia syndrome (POTS) in children with neurological symptoms at disease onset. METHODS: A retrospective analysis was performed on the medical data of 88 children with the initial symptoms of the nervous system, such as transient loss of consciousness, dizziness, headache, and convulsion, who were finally diagnosed with VVS or POTS. RESULTS: Of the 88 children, there were 35 boys (40%) and 53 girls (60%), with an age of 4-15 years. The peak age of onset was between 10 and 13 years. All the children had the initial symptoms of transient loss of consciousness, dizziness, headache, and convulsion. Nervous system diseases were excluded by electroencephalography, cerebrospinal fluid examination, and cranial MRI. Of the 88 children, 53 (60%) were confirmed with VVS, and 35 (40%) with POTS, according to the results of head-up tilt test (HUTT). Five children with the initial symptom of transient loss of consciousness were misdiagnosed with epilepsy. Predisposing factors were determined for 59 children (67%), and prolonged standing was the most common factor, followed by change in body position and strenuous exercise. Premonitory symptoms were observed in 66 children (75%), among which chest discomfort was the most common symptom, followed by gastrointestinal symptoms (nausea, vomiting, and abdominal pain) and pale complexion. All 88 children received health education and exercise for autonomic nerve function, among whom 53 children with VVS were given oral rehydration salts and 35 children with POTS were given oral rehydration salts and metoprolol. All 88 children were followed up for 18 months, and the response rates to the above treatment at 3, 6, 12, and 18 months of follow-up were 87%, 93%, 93%, and 90% respectively. CONCLUSIONS In addition to nervous system diseases, functional cardiovascular diseases including VVS and POTS should be considered for children with the initial symptoms of transient loss of consciousness, dizziness, headache, and convulsion. HUTT can be used to make a confirmed diagnosis, and the early treatment can achieve a good outcome.

The aim of this study was to investigate the expression and immunologic regulation function of interleukin-23 and its related cytokines in chronic idiopathic thrombocytopenic purpura (ITP) patients. Levels of cytokines in peripheral blood mononuclear cells (PBMNC) were detected by reverse-transcription real-time polymerase chain reaction in 30 patients with chronic ITP and 15 healthy volunteers. The quantity of IL-23, IL-12, IL-17 in serum was detected by enzyme-linked immunosorbent assay (ELISA). The results showed that low detectable mRNA levels of IL-23p19, IL-12p35, IL-27 and IL-12p40 were found in all patients and healthy persons. Trace of IL-17 mRNA were expressed in PBMNC of part of patients and normal controls. Levels of IL-12p35, IL-27, IL-17 mRNA between healthy persons and chronic ITP patients were not statistically different. Compared with normal controls, patients showed the lower expression levels of IL-23p19 and IL-12p40 mRNA (p < 0.01). The IL-12 levels of chronic ITP patients were significantly higher than that of normal controls (p < 0.01). The IL-23 and IL-17 levels of chronic ITP patients were same to that of normal controls. It is concluded that the imbalance of T cell subsets in ITP patients mainly associated with IL-12, but not with IL-23 and IL-17.
