Thirty mothers of four dadys later after delivery with agalactia, whose babies needed additional milk over one third of physiological needs, or agalorrhea were chosen to take 125 g of MUYINGLE divided into 3 parts a day for observing its lactigenous effect, and thirty other agalactous mothers, who might chose any kind of traditional Chinese lactagogue foods to eat, as control group. Those subjects whose babie's additional milk was less than one fourth or half of physiolgical needs for agalactia or agalorrhea respectively after four days with MUYINGLE were effectual. The results showed that the lactagogue efficacious rate of MUYINGLE and control group were 86. 7% and 33. 3%, respectively. The lactagogue effects were significant difference between the two groups (P

Objective To investigate the effects of hypertension on left atrial myocardial properties by strain and strain rate(SR)imaging.Methods A total of 56 consecutive patients with hypertension were divided into 2 groups:33 with normal LVMI and 23 with left ventricular hypertrophy.These patients and 20 controls underwent transthoracic echocardiography,strain and SR imaging examination.Atrial strain and SR values of hypertensive patients were compared with those of controls.Results When compared with the controls,early diastolic SR(ESR)was significantly decreased in hypertensive patients(P＜0.01-0.001),with time to peak late diastolic SR corrected for heart rate(TASRe)significantly increased in normal LVMI subgroup(P＜0.05).Moreover,late diastolic SR(ASR)were significantly decreased(P＜0.05)in hypertensive patients with left ventricular hypertrophy as compared with normal LVMI.Conclusions Enlargement of left atrium leads to increased reservoir function in hypertensive patients,which compensates for the deterioration of conduit function.The duration of atrial systole may be prolonged to meet the need of ventricular filling in consequence of lower left atrial booster pump function.Noninvasive quantification of left atrial function by SR imaging enables evaluation of left atrial dysfunction due to hypertension.

Objective To investigate the effect of malignant tumor on neuromuscular block of cisatracurium. Methods Sixty ASA Ⅰ or Ⅱ patients with head and neck neoplasms (15 cases with benign tumor, 45 with malignant tumor), aged 18-64 yr, were randomly divided into 4 groups ( n = 15 each): Ⅰ benign tumor group (group B,3 × ED95 ); Ⅱ -Ⅳ different dose cisatracurium group (group C1 (2 × ED95 ), C2 (3 × ED95 ) and C3 (4 ×ED95)). Neuromuscular block was assessed with accelerograph F (TOF-watch SX). Single stimulation of ulnar nerve was used. Anesthesia was induced with TCI of propofol (target plasma concentration 3 μg/ml) and remifentanil (target effect-site concentration 3 ng/ml). Tracheal intubation was facilitated with cisatracurium 0.15 mg/kg in group B, and with cisatracurium 0.10, 0.15 and 0.20 mg/kg in group C1, C2 and C3 respectively. The onset time, clinical duration, time for recovery of T/Tc to 75 % and recovery index were recorded. Results The clinical duration, time for recovery of T/Tc to 75 % and recovery index were significantly longer in group C2 than in group B (P ＜ 0.05). The onset time was significantly shorter, while the clinical duration and time for recovery of T/Tc to 75% were significantly longer in group C2 and C3 than in group C1 , and in group C3 than in group C2 ( P ＜0.05) .Conclusion The duration of action and recovery times of cisatracurium were prolonged in patients with malignant tumor.

Objective To assess the short-time economics of various glutamine dipeptide-enriched parenteral nutrition (PN) for patients undergoing elective surgery for gastrointestinal tumors, with an attempt to provide evidence for decision makers on clinical nutrition support.Methods A prospective cohort study was designed.From payer/disburser''s perspective, a cost-effectiveness decision-tree model was developed to assess the clinical outcomes and short-time economic effects of glutamine dipeptide-enriched PN that used in different time points (early postoperative or perioperative).Cost-effectiveness analysis, cost-utility analysis, and incremental cost-effectiveness analysis were adopted in the decision-tree model.One-way sensitivity analysis was performed to determine the robustness of the results.Results Totally 107 patients were included.There was no significant difference between the perioperative alanine(Ala) glutamine(Gln) nutrition support (group A) and early postoperative Ala-Gln nutrition support (group B) in the ratio of 5％ weight declines on the 8th day after surgery and infection-related postoperative complications (72.1％ vs.78.1％, χ2=0.509, P=0.498 and 2.32％ vs.4.69％, χ2=0.060, P=0.806).The levels of prealbumin (PA) and albumin(Alb) and the level of total lymphocyte count(TLC) also the time of recovering gastrointestinal function, length of stay nutritional discharge index(LOSNDI), and direct costs were significantly different [PA:(208.19±56.92)mg/L vs.(187.97±62.05)mg/L, t=2.283,P=0.039;Alb:(33.82±3.91)×109 vs.(31.96±4.57)×109, t=2.184, P=0.036;TLC:(1.19±0.55)×109 vs.(0.89±0.66)×109, t=2.461, P=0.015;the time of recovering gastrointestinal function(3.06±0.28)d vs.(3.39 ± 0.34)d, t=-3.675, P=0.000;LOSNDI:(16.84±2.92)d vs.(18.52 ±3.47)d, t=-2.613, P=0.011;direct costs:￥(17 029.05±317.28) vs.￥(15 610.64±292.56), t=23.764, P=0.000].When LOSNDI and quality-adjusted life years (QALYs) were estimated as indicators of effectiveness, the incremental cost-effectiveness ratios and incremental cost-utility ratios of group A were ￥844.3 and ￥70 920.5, respectively.Net monetary benefit of group B was more than that of group A.One-way sensitivity analysis showed that parameters had no significant effect on the model.Conclusion When using local per capita gross domestic product as threshold, early postoperative Ala-Gln PN was more economical than perioperative Ala-Gln PN strategy evaluation.
