Objective To study the effect of early pulmonary surfactant (PS) treatment on oxygenation in neonates with acute respiratory distress syndrome (ARDS). Methods Clinical data of neonates with ARDS were retrospectively analyzed. All neonates with ARDS were divided into control group and treatment group. Neonates in treatment group were given PS at a dose of 70-100 mg/kg through the endotracheal tube. Results Among 64 neonates with ARDS, 18 neonates in treatment group were treated with PS, while other interventions were same with 46 neonates in control group. The PaO2/FiO2 and ventilation efifciency index were statistically higher in treatment group than those in control group at 6 h, 12 h, 24 h and 48 h (P<0.05). The oxygenation index and respiratory index were statistically lower in treatment group than those in control group at the same time points (P<0.05). Compared with control group, the treatment group also had a signiifcantly shorter duration of assisted ventilation and oxygen treatment (P<0.05). Conclusions Early treatment with PS in neonates with ARDS could improve the pulmonary compliance and oxygenation, and reduce the duration of assisted ventilation and oxygen treatment, and thus yield better prognosis.

Objective To study the oxygenation of the pulmonary surfactant replacement therapy for acute lung injury (ALI) and acute respiratory distress syndrome (ARDS) in neonates.Methods Ninetyeight eligible neonates with ALI and ARDS were divided into two groups,treatment group (n =30) and control group(n =68).Thirty infants in treatment group were injected with pulmonary surfactant 70 ～ 100 mg/kg via tracheal intubation.The rest of the treatment measures were same in treatment and control group.Results There were no differences between the two groups in gender,gestational age,birth weight and ALI/ARDS.After the pulmonary surfactant replacement therapy for ALl and ARDS,the PaO2/FiO2 and ventilator efficiency index were higher in treatment group than that in control group at 6 h,12 h,24 h,48 h;the oxygenation index and respiratory index were shorter in treatment group than that in control group at the same time.The differences at all time points were statistically significant (P ＜ 0.05).The treatment group also had a significantly shorter duration of assisted ventilation[(66 ± 13) h vs (80 ± 18) h,(82 ±26) h vs (101 ±36) h] and oxygen treatment time [(86±13) h vs (104± 16) h,(103 ±25) h vs (125 ±29) h] (P ＜0.05).Conclusion The application of the pulmonary surfactant replacement treatment in neonates with ALI and ARDS could improve rapidly in dynamic compliance and oxygenation,decrease duration of assisted ventilation and supplemental oxygen administration,thus yield better prognosis.

This study was conducted under the background of the internationalization of traditional Chinese medicine (TCM) terminology. Current TCM symptom terminology related to sweat was taken as basis in the extended study. The ICD classification of multiple axis and hierarchical level was used as guidance thought. This paper proposed the principle of detailed classification of TCM sweat symptoms and finally made classification rules for TCM sweatsymptoms. This study has promoted the development of TCM terminology standardization.

Objective To summarize anesthetic management for 56 patients undergoing off-pump coronary artery bypass grafting (OPCABG). Methods Recorded and analyzed the hemodynamie changes of 56 patients undergoing OPCABG including heart rate (HR),rate-pressure product (RPP), mean arterial pressure(MAP), mean pulmonary artery pressure(MPAP), central venous pressure (CVP), cardiac output (CO) and mixed venous oxygen saturation when left anterior descending (LAD), right coronary artery (RCA), diagonal (DiAG) and left circumflex coronary artery (LCX) was anastmosed. Results The patients undergoing OPCABG had hemodynamic fluctuation during vascular anastomosis, mainly showing MAP and CO decreased, CVP increased. The change was especially significant when the LCX or RCX was anastmosed. The based value, when LAD and RCA anastmosed of MAP were (82.0±11.7) mm Hg(1 mm Hg = 0.133 kPa), (60.1±11.5) mm Hg and (58.4±12.1) mm Hg, CO were (4.2±1.2) L/min, (3.1±0.7) L/min and (3.2±0.6) L/min, CVP were (5.6±2.6) cm H2O (1 cm H2O=0.098 kPa), (9.6±4.4) cm H2O and (9.2±3.6) cm H2O. Conclusion The hemodynamie changes during OPCABG,especially in LCX and RCA anastmesed are transient and well tolerated under suitable anesthetic management.

Objective:To determine distribution of fungal florae of candial balanoposthitis (CBP),the relatioship between antibiotics administration and candial infection and the major source of opportunistic pathogens.Methods:The fungal strains were collected and identified,and the history of antibiotic administration was reviewed.Results:①Foreign fungi were predominant pathogens of CBP;②Dysbacteriosis induced by antibiotics stimulated the growth of foreign fungi,which resulted in CBP;③There was a positive relationship between fungal distribution of male patients and their sexual partners.Conclusion:In order to reduce the incidence of CBP safe coition and reasonalbe administration of antibiotics should be emphasized.

Objective: To investigate the alteration of red cell deformability (RCD) and adenosine triphosphatase (ATPase) activity of cell membrane in essential hypertensive (EH) patients and essential hypertension patients complicated with cerebral infarction (HCI). Methods: Twenty healthy individuals, 30 EH patients and 30 HCI patients were selected as subjects. The erythrocyte deformability indexes (DI)、 Na+, K+-ATPase and Ca2+ATPase activities were examined. Results: (1) EH patients had significantly higher DI, lower ATPase activity as compared to healthy individuals. There were significantly negative correlation between DI and ATPase activity, and a significantly positive correalation between DI and diastolic blood pressure in EH patients; (2) There was significantly higher DI, lower ATPase activity in HCI patients than those in EH patients. There was significantly negative correlation between DIand ATPase activity in HCI patients. Conclusion: (1) RCD decreases in EH patients, and RCD is correlated to the decreased ATPase of cell membrane and elevated blood pressure; (2) The decreased RCD level may be related to the occurrence of HCI.

Methods The herbage-contained serum of Tongmai Tang and oxLDL were prepared, then the human HUVEC-304 cells were divided into 4 groups: ⑴control group; ⑵bovine serum control group; ⑶oxLDL group: 100mg/L oxLDL, and ⑷Tongmai Tang group: 5% herbage-contained serum of Tongmai Tang and 100mg/L oxLDL. After 24h incubation, the morphology of the endothelial cells was observed under the inversion microscope, while the concentrations of NO, t-PA and PAI-1 in the culture medium were measured. Results ⑴The endothelial cells in oxLDL group were seriously injured, while those in Tongmai Tang group got better; ⑵the concentrations of NO and t-PA in the oxLDL group were significantly lower than those in the control group(P

Methods The serum containing Tongmai effective components was extracted and used to interfere the anoxic myocardial cell, then the concentration of the LDH and troponin I in the culture medium of the cardiac myocyte was measured. Results The concentration of LDH and troponin I increased significantly in the culture mediun of the anoxic cardiac myocyte. The intervention of the serum containing Tongmai can significantly decreased the concentration of LDH and troponin I in the culture medium of the anoxic cardiac myocyte. Conclusion Tongmai can protect the cardiac myocyte from anoxic damage.
