Measurement of whole blood CL was carried out to evaluate phagocytic of function of PMNL and opsonic activity of plasma from children (22 cases), adults (31), newborn infants (umbilical cord blood, 21), patients with bacterial infection (31), viral infections (21),and mild anemia (10). The following results were obtained: first, phagocytic function of PMNL and opsonic activity of plasma from normal children was compared to adults; second, phagocytic and/or metabolic activity of PMNL and opsonic ativity of plasma from newborn infants were lower then normal, third, PMNL of the patients with bacterial infections had been preactivated in vivo, their phagocytic function being enhanced, but, blood from the patients with viral infections showed almost no abnormalities; fourth, phagocytic activity of PMNL from the patients with mild anemia was similar to normal human. The significance of the results was also discused in the paper.

This paper briefly analyzed and discussed the current status and major scientific challenges of traditional Chinese medicine (TCM) formulaology research. To promote formulaology research, a new strategy and corresponding technology, network formulaology, were proposed to reveal the complex interaction between functional chemome and biological responses network. The research framework and directions of network formulaology were also summarized and prospected.

Objective To investigate the effect of perioperative pulmonary infection in elderly patients with mild to moderate chronic obstructive pulmonary disease (COPD) undergoing general anesthesia.Methods Forty elderly patients undergoing general anesthesia and abdominal surgery, 24 males, 16 females, aged 65-81 years, ASA physical status Ⅰ-Ⅲ, BMI 19-28 kg/m2, were randomly divided into two groups (n=20 each): protective ventilation group (group PV) and conventional ventilation group (group CV).Lung protective ventilation was received in group PV: intermittent positive pressure ventilation, tidal volume 6 ml/kg (ideal body weight), positive end expiratory pressure (PEEP) 5-10 cm H2O, alveolar recruitment maneuver every 30 minutes;conventional ventilation was received in group CV: intermittent positive pressure ventilation, tidal volume 10 ml/kg (ideal body weight), without using the PEEP and alveolar recruitment maneuver.Venous blood samples for interleukin 6 (IL-6) and interleukin-8 (IL-8) were taken at five different time points: before the anesthesia induction (T1), 2 h after mechanical ventilation (T2), at the end of operation (T3), 6 h (T4) and 24 h (T5) after operation.The clinical pulmonary infection score (CPIS) was recorded at before anesthesia, days 1, 3, 5 and 7 after surgery.The incidence of postoperative pulmonary inflammation was also recorded.Results There was no statistical difference in the two groups with respect to age, body mass index, ASA physical status, intraoperative volume of infusion, estimated blood loss, urine volume, mechanical ventilation time, operation method and IL-6, IL-8 levels at T1-T5.Compared with T1, the IL-6 and IL-8 levels in two groups at T2-T5 increased significantly (P＜0.05).Compared that before anesthesia, CPIS in group CV on postoperative days 1, 3 and 5 increased significantly (P＜0.05);compared with group CV, CPIS and the incidence of postoperative pulmonary inflammation in group PV reduced significantly on postoperative days 1, 3 and 5 (P＜0.05).Conclusion Lung protective ventilation can not reduce perioperative IL-6, IL-8 levels in laparotomy elderly patients with COPD, but it can reduce the incidence of pulmonary inflammation and pulmonary infection within 5 postoperative days.

Objective:To investigate the effect of esculentoside (EsA) on apoptosis of murine thymocyte. Methods:Using electronic microscope, DNA agarose electrophoresis and flow cytometry analysis,the effect of EsA on apoptosis of murine thymocyte was examined. Results:The result showed that apoptosis of activated thymocyte by ConA was markedly promoted by 2.5, 5, 10 ?g/ml EsA in murine thymocyte culture for 3 h, but the spontaneous apoptosis was not affected by EsA. Conclusion:The results suggest that EsA has the positive effect on apoptosis of activated murine thymocyte.

ObjectiveTo observe the effect of rat cerebral hemorrhage model via autologous blood injection.MethodsBlood extracted from rats' cardiac ventricles was injected into the right caudate nucleus via stereotactic method. Pathological examination,ultrastructural visualization and motor functional test were applied to validate the feasibility of this method.ResultsRats showed paralysis of left extremities rapidly after surgery. Pathological examination confirmed the formation of hematoma in caudate nucleus. The deviation of hematoma volume and location among individuals was significantly lower than that of rats made by collagenase injection. Transmission electron microscopy showed wide mylin degeneration in right caudate nucleus. Motor functional test revealed the dysfunction of left extremities with marked lower deviation among individuals compared with that of collagenase injection (P<0.05).ConclusionAutologous blood injection can result in significantly lower deviation of hematoma volume and location as well as dysfunctional degree compared with that of collagenase injection.

In order to assess the effect of long-term versus short-term intravesical chemotherapy in preventing the recurrence of patients with non-muscle-invasive bladder cancer, we searched several databases with words as mesh terms and free text words to find all eligible randomized clinical trials (RCTs) for the comparison of the two strategies of instillation durations. "Observed-Expected events research (O-E)" and "Variance (V)" for calculating hazard ratio (HR) were used in Revman 5.2 software recommended by Cochrane Collabration for data analysis. Sensitivity and subgroup analysis were selected to minish heterogeneity. GRADEpro 3.6 profile recommended by Cochrane Collabration was employed for quality assessment of analyses. Finally, 13 eligible RCTs with 4216 patients were included in this review and 16 comparisons from 13 trials were involved for analysis. The pooled analysis revealed no significant difference between long-term and short-term duration [HR=0.99, 95% CI (0.89, 1.11), P=0.89]. Within the subgroup analysis, patients benefited from long-term instillations with a start regimen of one immediate instillation [HR=0.83, 95% CI (0.69, 1.00), P=0.05]. But patients were not suitable to receive long-term instillations with epirubicin (EPI) [HR=1.01, 95% CI (0.91, 1.13), P=0.78]. The progression rate was not reduced after long-term instillations [HR=0.96, 95% CI (0.66, 1.39), P=0.82]. From our results, patients should not receive introvesical chemotherapy more than half a year. In contrast, patients with one immediate instillation are preferred to have a long-term duration at least one year. Long-term instillations can not reduce the progression rate.

Analogous formulae (AF) refer to a set of traditional Chinese medicine (TCM) formulae sharing similar herbs and/or indications. Dissecting functional chemome of analogous formulae could enhance the understanding of the intrinsic nature of TCM. In this study, taking 5 Xiaoqinglong decoction analogous formulae (XQL AF) including Xiaoqinglong decoction, Mahuang Xingren Shigao Gancao decoction, Mahuang Fuzi decoction, Houpu Mahuang decoction and Daqinglong decoction as example, we systematically investigated the relationship between compounds and indications using network formulaology approach. The functional chemome of XQL AF were revealed by network analysis and molecular docking. This successful application in XQL AF suggests network formulaology could be a useful tool for AF-related research and therefore provide a new way to discover the scientific foundation of Zhang Zhongjing's herbal formulae.
