Objective To investigate the infection status of infectious diseases for 2 521 patients before blood transfusion in a Hospital in Changsha.Methods A total of 2 521 patients who would be transfused were selected,and six kind of serum hepatitis B virus indicators,hepatitis C virus antibody (antiHCV),human immunodeficiency virus antibody (anti-HIV/1 + 2),and treponema pallidum antibody (antiTP) of nine common infectious disease targets were detected with enzyme-linked immunosorbent assay (ELISA).Results Among 2 521 patients,HBsAg-positive cases were 8.33％,anti-HCV positive were 0.59％,anti-HIV positive [confirmed by the Provincial Center for Disease Control (CDC)] was 6 cases,and TP-positive were 2.301％.A total of 289 patients were tested positively,with a total positive rate of 11.46％.Conclusions Detection before transfusion may reduce infection risk and decrease the risk of occupational exposure,strengthen medical staff self-protection,and reduce medical malpractice caused by blood transfusion.

This study was aimed to observe the effect ofZi-Bu Pi-Yin Recipe (ZBPYR) on the mRNA expressions of NMDA receptor subunits NR1, NR2A, NR2B in different brain regions of spleen-yin deficiency Alzheimer's Disease (AD) model rats. The levels of NR1, NR2A, NR2B mRNA expressions were detected by using RT-PCR method. The results showed that the levels of NR1, NR2A, NR2B mRNA expressions of AD group and spleen-yin deficiency AD group decreased significantly (P < 0.05). The levels of NR1, NR2A, NR2B mRNA expressions of ZBPYR treatment group increased significantly (P < 0.05). It was concluded that the expression levels of NMDAR mRNA in different brain regions of the ZBPYR treatment group increased significantly, which indicated that ZBPYR may up-regulate the protein expressions of NMDAR by increasing the expression levels of NMDAR mRNA, thereby to play the anti-dementia effect.

Objective To investigate the dementia caregivers' awareness of dementia diagnosis for patients aged≥80 years in veterans community in Beijing.Methods Patients aged 80 years and over who were diagnosed as dementia were selected from Dec.2009 to Jul.2011 in the veterans community in Beijing.A face-to-face interview and questionnaire survey were conducted in dementia caregivers individually,including basic social demographic data (gender,age,educational background),awareness rate of dementia,treatment and drug use situation and their attitude to dementia patients.Results A total of 118 caregivers were investigated individually.The caregivers in this study were mainly the spouse of the patients,and most of them were elderly people.46.6％ (55/118) of caregivers were the spouse of the patients,and 52.5％ (62/118) of caregivers were 65 years old and over.The caregivers' awareness rate of dementia was 32.3％ (38/118) when patients were diagnosed as dementia.There was no correlations of gender,age and educational background with the awareness rate of dementia diagnosis (all P＞0.05).50％ of dementia patients received the dementia treatment,and only 17.8％ (21/118) of patients got the first line drug treatment for dementia (acetylcholinesterase inhibitors and / or memantine).98.3 ％ (116 / 118) of caregivers agreed that the dementia patients should be treated kindly.Conclusions The dementia caregivers are mainly patients' spouse in veterans community and most of them are the elderly.The awareness rate of dementia diagnosis is low among the caregivers.Most patients do not take the formal treatment.The social support for the dementia caregivers should be strengthened.

Objective To explore the relationship between the objective indexes and TCM syndromes of occupational hand arm vibration disease ,and to provide clinical data for the objectification of TCM syndrome differentiation. Methods 101 patients with occupational hand arm vibration disease were collected ,including 24 patients with Xingbi,39 with Tongbi and 38 with Zhuobi,according to the theory of traditional Chinese medicine syndrome differentiation ,the relationship was observed between different TCM Syndrome types and various of parameters,such as 5-and 10-minute rewarming rates in cold water rewarming test,terminal latency,amplitude, conduction velocity ,average time ,average amplitude of abductor pollicis brevis and abductor digiti minimi in electromyography. Results 5-and 10-minute rewarming rate in cold water rewarming test did not differ significantly among the three groups(P > 0.05). Amplitude of median nerve motor conduction differed significantly among the three groups of Xingbi,Tongbi and Zhuobi(χ2 = 6.14,P < 0.05),Further comparison between the groups was made in Xingbi and Tongbi(χ2=0.132,P=0.895),Xingbi and Zhuobi(χ2=2.277,P=0.023),Tongbi and Xingbi (χ2 = 2.172 ,P = 0.030). There were no significant differences among the three groups in latency and conduction velocity of the median nerve motor conduction and latency ,amplitude and conduction velocity of ulnar nerve motor conduction(P>0.05). The differences of conduction velocity and amplitude of median nerve and ulnar nerve sensory conduction,average time and average amplitude of abductor pollicis brevis and abductor muscle among the three groups had no statistical differences(P>0.05). Conclusions The distribution is different in the amplitude of median nerve motor conduction among the three groups of Xingbi,Tongbi and Zhuobi,further analysis shows that the difference is mainly reflected in the Xingbi group. We conclude that the median nerve axonal injury is lighter in Xingbi group than in the other two groups.
