Objective To investigate awareness of knowledge about iron deficiency anemia (IDA)in patients with it.Methods Patients diagnosed as IDA at their initial visits to Affiliated Hospital of Qingdao University Medical School were randomly selected for the study during January 2008 to January 2009 with self-designed questionnaire to investigate their awareness of knowledge about IDA.Results Among 199 patients with IDA investigated, their awareness was lower in general, five percent about its etiologies, 34.2 percent about its clinical manifestations, 18.1 percent about its hazard to health, and two percent about food abundant of iron.For preventive measures of IDA, 50.7 percent (101/199) of them knew that daily diet should be diversified and 43.7 percent (87/199) knew that meals should be prepared with ferric cooking pot.Awareness of knowledge about other preventive measures of IDA was lower in them.No significant difference in awareness of IDA-related knowledge between them at varied ages was found, except for knowledge about etiology and hazard of IDA.Awareness of etiology of IDA differed between them at varied ages (P ＜0.05), and about 75.3 percent (64/85)of patients with IDA aged 30 -45 years were caused by chronic blood loss.There was no significant difference in awareness of IDA-related knowledge between patients with IDA caused by varied etiologies (P ＞ 0.05).Conclusions In general, awareness of IDA-related knowledge was lower in patients with IDA.It is necessary to strengthen its popularization, with varied focuses in preventive measures for IDA patients with different etiologies.

Objective To examine the validity and reliability of the abbreviated mental test (AMT) among Chinese subjects. Methods Two groups of subjects participated in the study. One group consisted of 38 patients with neurological disorders and the other 30 normal subjects (control group). They were assessed twice with AMT and mini mental state examination (MMSE) within one week. Results AMT was significantly correlated with MMSE as far as the total score and item scores were concerned( r =0.706～0.833).There were moderate to high correlation in all the items of AMT between the two assessment tools(ICC=0.810～0.996). The AMT scores in the patient group were significantly lower than that in the control group (7.60?2.55 vs 9.64?0.81, P

0.05). There was no neoplasia appeared at 12 weeks after implantation. Pathological section showed that nerve cell and medullary sheath were integrated without fibroplasia or necrosis, and only a little of infiltration of lymphocytes appeared. CONCLUSION: Activity and secretion function can be kept by the microencapsulation technique on PC12 cells. When microencapsulated PC12 cells were implanted into subarachnoid cavity, the cells can maintain good activity and secretion without oncogenicity.

Objective To study the reliability, validity, sensitivity, specificity and predictive value of the Standardized Swallowing Assessment (SSA) in assessing swallowing function. Methods Sixty-seven stroke patients with dysphagia participated in the study. They were assessed twice with the SSA within 3 days. In addition, the patients' swallowing was also assessed using videofluoroscopy. Results There was high correlation in all items of the SSA between the two separate assessment sessions. The intraclass correlation coefficient was 0.85 for intrarater re- liability and 0.82 for interrater reliability. The SSA and videoflouroscopy results were highly correlated in terms of their total scores (r = -0.86,P≤0.01). Using the videoflouroscopy result as the standard, the sensitivity and spe- cificity of the SSA were 77.8% and 68.1% , respectively. At the same time, the positive and negative predictive val- ues were 48.3% and 88.9% , respectively. Conclusions The SSA has satisfactory reliability and validity, and higher sensitivity and specificity than videoflouroscopy. It is recommended for assessing swallowing with stroke pa- tients.

Objective To explore the clinical curative effect of hyperbaric oxygen therapy for severe cranio-cerebral injury,and its influence on the level of serum interleukin -1 beta(IL -1 )and interleukin -6(IL -6). Methods 150 patients with severe craniocerebral injury were selected and divided into two groups by random and single blind method.75 patients of the control group were treated with conventional therapy,75 patients of the observation group were given hyperbaric oxygen on the basis of the conventional treatment,and the clinical efficacy was compared between the two groups.Results The total effective rate of the observation group was 94.67%,which was significantly higher than 77.33% of the control group,the difference was statistically significant(χ2 =7.83,P <0.05).There were no significant differences in GCS and ADL scores between the two groups(t =1.22,2.39,all P >0.05).After treat-ment,the GCS and ADL scores of the observation group were (12.18 ±2.13)points,(67.46 ±12.55)points,which were significantly higher than those before treatment(t =8.01,7.76,all P <0.05),and there were significant differ-ences between the two groups(t =7.23,6.82,all P <0.05).Before treatment,there were no significant differences in the serum levels of IL -6 and IL -1 between the two groups(t =2.10,1.01,all P >0.05).After treatment,the serum levels of IL -1 and IL -6 in the observation group were (127.48 ±16.35)pg/mL,(89.66 ±13.47)pg/mL, which were significantly lower than before treatment(t =8.34,7.89,all P <0.05),there were significant differences between the two groups(t =7.65,7.22,all P <0.05).Conclusion Implementation of hyperbaric oxygen in patients with severe traumatic brain injury on the basis of conventional symptomatic treatment can effectively improve the clinical symptoms and signs,reduce the serum IL -1 and IL -6 levels,promote the recovery of brain function and ability of daily life,and which is worth to be promoted in clinical.

Objective To investigate the optimal time of termination of pregnancy for patients with hemolysis elevated liver enzymes and low platelet (HELLP) syndrome Methods 57 patients with HELLP syndrome admitted from October 1992 to September 2001 were enrolled According to the length from the time diagnoses confirmed to the time of delivery,patients were divided into 3 groups; group Ⅰ,within 24 hours, group Ⅱ,24 to 48 hours and group Ⅲ,over 48 hours Complications,maternal and perinatal mortality were analyzed retrospectively between different groups Results Maternal and perinatal mortality were 7% and 11% in group Ⅰ, 16% and 21% in group Ⅱ, 64% and 73% in group Ⅲ with significant differences between group Ⅲ and group Ⅰ or group Ⅲ and group Ⅱ ( P

Objective To investigate the relationship between the degree of serum cortisol suppression by low-dose dexamethasone (1 mg) and full serum cortisol suppression (suppression rate > 50% ) by high-dose dexamethasone (8 mg) in patients with Cushing syndrome, and to evaluate these tests in Cushing disease. Methods Ninty-one patients with Cushing syndrome were studied retrospectively. The relationship of 20%, 30%, 40%, and 50% cortisol suppression by overnight 1mg dexamethasone with full serum cortisol suppression by overnight 8 mg dexamethasone was analyzed, and the sensitivity and specificity in the diagnosis of Cushing disease were evaluated. Results The degree of cortisel suppression during overnight 1 mg dexamethasone suppression test was correlated with that during overnight 8 mg dexamethasone suppression test (r=0. 649,P<0. 001 ). 30, 22, 13, and 9 patients had greater than 20%, 30%, 40%, and 50% serum cortisol suppression respectively during overnight 1 mg dexamethasone suppression test. Among them, 23 ( 76. 7% ), 20 (90. 9% ), 12 (92.3%), and 9 ( 100.0% )patients had full serum cortisol suppression during overnight 8 mg dexamethasone suppression test. The sensitivity of the cutoff of greater than 20%, 30%, 40%, and 50% serum cortisol suppression for the diagnosis of Cushing disease was 52.8%, 32.7%, 22.6%, and 15.7%, and the specificity was 94.7%, 94.7%, 97.4%, and 97.4% respectively. Conclusions In patients with Cushing syndrome, greater than 20% serum cortisol suppression during overnight 1 mg dexamethasone suppression test is usually associated with full serum cortisol suppression during overnight 8 mg dexamethasone suppression test, and most of them are finally diagnosed as Cushing disease.
