Objective To evaluate the effect of different types of tube feeding on swallowing function of stroke patients. Methods 60 patients with dysphagia post stroke were divided into observation group and control group with 30 cases in each group. The control group received indwelling nasogastric tube feeding, and the observation group received intermittent nasogastric tube feeding. They were assessed with Kubota Water Swallow Test (WST) and VGF on the 1st day and 30th day after admission. Results The scores of drinking test and VGF were better in the observation group than in the control group (P<0.05) on the 30th day. Conclusion Long-term nasogatric tube feeding is effective on dysphagia in stroke patients.

As unrelated allogeneic umbilical cord blood transplantation (UCBT) has been developed for 20 years already since 1988, more than ten thousands cases have cumulatively undergone UCBT over the world. A huge number of clinical data confirmed that UCBT had unique characters with low rate of severe GVHD. The efficacy and data on TRM, relapse and EFS of allogeneic UCBT with HLA 0-1 mismatched are similar to those in HLA matched BMT. UCBT has become the optimal choice for source of hematopoietic stem cells for allogeneic stem cell transplant especially when HLA-matched or haploidentical donors are not available in time. In most developed countries, unrelated allogeneic UCBT developed successively, and in recent years HLA mismatched UCBT with double units performed in adults increased even more rapidly than in children. Another recent trend of UCBT has been extending to treat some non-malignant but refractory diseases in pediatrics, such as severe combined immunodeficiency, thalassemia major, bone marrow failure syndrome and metabolic disorders. The clinical successful practice of double units for cord blood transplantation inspires to ponder over questions remaining mystery. What is the conflict like between two mismatched donor cells in vivo, which does not spoil the whole transplantation but enable the patient to be engrafted successfully without any increment of the dosage by the sum of two doses together? How can they both be taken at the same time firstly by the recipient, but why does only one predominate later? What are the factors enable the donor cells of the winner to sustain? With the references of the international experiences, how to solve the clinical encountered problems, perspective of unrelated allogeneic UCBT and proper strategies to be enacted are reviewed.

Objective To investigate the correlation of blood lipid metabolism abnormity and other components of metabolic syndrome on angiocardiopathy and cerebrovascular diseases in the elderly people. Methods The clinical data of elderly people, who underwent medical examination during 1996 to 2005 in the General Hospital of PLA, were retrospectively analyzed. Based on the analysis, the co-existence of blood lipid disorders with glucose metabolic abnormity, hypertension and obesity, as well as their influence on cardio-cerebrovascular diseases were further analyzed. Results The prevalence of blood lipid metabolic disturbance was 69.6%, in which the prevalence of hyper-cholesteremia and hyper-triglyceride were 23.6% and 21.7%, respectively. The prevalence of hyper-cholesteremia accompanied by hyper-triglyceride (mixed group) was 19.3%, that of hyper-triglyceride with lower high density lipoprotein cholesterol was 5.03%, while it was 30.4% in the normal group. There was a higher risk of having the above abnormal condition in patients with type 2 diabetes mellitus (T2DM) and obesity, and they were more frequently complicated by hypertension in the hyper-triglyceride group (70.8%). When the patients with lipid metabolic disturbance were complicated by T2DM, hypertension and obesity, the prevalence of cardiovascular or cerebrovascular diseases increased. The prevalence of CHD was higher in the patients with hyper-cholesteremia and hypertension or diabetes, and incidence of both CHD and CVD was higher in the patients with hyper-triglyceride and either one of hypertension, diabetes or obesity. Conclusion There is high prevalence of lipid metabolic disturbance (more than two thirds) and other components of metabolic syndrome, and high risk of suffering from cardiovascular or cerebrovascular diseases in elderly people. The aging patients with hyper-triglyceride are vulnerable to cardiovascular or cerebrovascular diseases, and more attention should be paid in clinical practice in future.

The work was carried out to investigate the effects of clonidine on Ach quantal release of presynaptic nerve terminals in guinea pig celiac ganglia in vitro by means of intracellular recording technique. After perfusion of celiac ganglia with clonidine ( 10?mol/L ) for 7 ~10 min, the frequency of spontaneous miniature excitatory postsynaptic potentials ( mEPSP ) which was increased by high K+ (15 mmol/L ) , diminished about 35% with little change in amplitude. Under condition of low Ca2+( 0.5mmol/L )/high Mg2+( 5.5mmol/L ) presynaptic nerve was repetitively stimulated by 200 pulses ( 1 Hz), the failure number of EPSP increased from 82 to 145 in 200 stimuli and the quantal content ( m ) decreased about 62% with little change in quantal size ( q ) under clonidine ( 10?mol/L ) action. It is indicated that clonidine can decrease Ach auantal release from presynaptic nerve terminals without effecting Ach content in vesicles, and is one of the mechanisms for depressant effect of clonidine on synaptic transmission of the sympathetic ganglia.

Objective To detect the percentage of cultured neuron apoptosis after the neurons were treated with anoxia and specific inhibitors of protein kinase A (PKA) and protein kinase C (PKC). Methods After establishment of the model of neurons cultured under hypoxic condition, the neurons were cocultured with different concentrations of Rp-cAMP and Calphostin C, specific inhibitors of protein kinase A and C, respectively. Then neurons were cultured under an ischemic condition until the number of survived neurons, the activity of mPKA,and mPKC, and the apoptotic neurons stained by TUNEL in each group were observed. Results The activity of mPKA and mPKC significantly increased after the onset of hypoxia. With the increases in concentrations of Rp-cAMP or Calphostin C, the percentage of apoptotic neurons obviously decreased or increased, respectively. Conclusion The pathways of PKA and PKC signal transduction may participate in the hypoxic neuron injury. The functions of these two kinases are opposite for apoptotic regulation. It suggests that the signal transduction of PKA and PKC in hypoxic neurons belongs to a monophasic controlling system and the ratio of PKA to PKC in cells may determine the survival of hypoxic neurons.

Objective: To study the daphnane diterpenoids of Trigonostemon lutescens form Guangxi province. Methods: The ethanol extract of T. lutescens was separated and purified by column chromatography, and the structures of the compounds were identified by physicochemical properties and spectral data. Results: Twelve daphnane diterpenoids were separated and identified form T. lutescens as trigoxyphin A (1), 3,16α-dihydroxy-kaurane (2), entkaurane-3,16α-diol (3), 10,16α-dihydroxy-isokaurane (4), entkaurane-3, 5,16α-triol (5), 8α-hydroxy-3,4-secopimara-4,15(18)-diene-3-oic acid (6), 8α-hydroxy-3,4-secopimara-4,15(18)-diene-3-oate (7), 3,4-secopimara-4,8(9),15(18)-triene-3-acid-methyl ester (8), trigoflavidone A (9), clerodane-2,4,11-triene-17-acid methyl ester (10), 3α-dihydroxy-kaurane-16-ene (11), and 13α-dihydroxy-kaurane-16-ene-18-acid methyl ester (12). Conclusion: All these daphnane diterpenoids are first separated and identified form T. lutescens.

Forty cases of bronchial asthma were treated by comprehensive methods of acupuncture, ear-embedding and acupoint-injecting. Thirty-six cases were treated by single body acupuncture and 38 cases were treated by herbal medicine for comparison. The therapeutic effects were analyzed among the three groups. The total effective rate was 95.0% in the comprehensive group, 80.6% in the single acupuncture group and 73.7% in the herbal medicine group, with a significant difference (P＜0.05) among the three groups. The combined use of acupuncture, ear-embedding method and acupoint-injecting method were better than single acupuncture and herbal medicine in the treatment of asthma.
