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 explore the relationships between the serum and urinary levels of procollagen Ⅲ and renal injury at the early stage of hypertension in sponantously hypertensive rats. Methods 16 sponantously hypertensive rats (SHR) were divided into treated group (losartan 30mg?kg -1?d -1) and untreated group, each group containing 8 animals, and 8 Wistar-kyoto rats served as normotensive control group(WKY). The serum and urinary levels of procollagen Ⅲ and ? 2-microglobin, and urinary microalbumin level were measured by radioimmunoassay 16 weeks after treatment. Results Blood pressure, serum ? 2-microglobin level, and the urinary levels of procollgen Ⅲ, ? 2-microglobin and microalbumin in SHR were significantly higher than those in wistar-kyoto rats. Losartan could decease the levels of the indices above in SHR. Serum procollagen Ⅲ level had not significant difference among the three groups of rats, and was not correlated with urinary procollagen Ⅲ level. There were positive correlation between serum and urinary ? 2-microglobin levels, and urinary procollgen Ⅲ level was positively retated to urinary ? 2-microglobin, urinary microalbumin and systalic pressure. Conclusion The levels of urinary procollgen Ⅲ,? 2-microglobin and microalbumin could reflect the lesion of glomerulus and tubulointerstitum at the early stage of essential hypertension in SHR.

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.

Objective:To study how to guide the individual dose of clopidogrel in line with the genetic testing results. Methods:Clinical pharmacists decided how to optimize the prescription of clopidogrel according to the genotype combined with the drug metabolism and drug interactions for three patients respectively with slow clopidogrel metabolism,intermediary metabolism and super fast metabolism. Results:The slow clopidogrel metabolism patient with subacute stent thrombosis after half a month of coronary stenting was switched to orally administrate with ticagrelor. The super fast metabolism patient suffered from repeatedly subcutaneous hemorrhage with antiplatelet therapy was suggested to lower the dose of clopidogrel,temporarily withdraw Maixuekang capsules and conventionally administrate with vitamin C tablets orally. The intermediary metabolism patient with late stent thrombosis co-treated with lansoprazole was suggested to increase the dose of clopidogrel or use ticagrelor instead,and when it was necessary,panxitorazole,ray Bella or the other ranitidine acid suppression drugs such as ranitidine could be considered. Conclusion:Through genetic testing and drug interactions,clinical pharmacists guide the clinical use of clopidogrel and the optimization of antiplatelet therapy.
