Objective To understand the levels of plasma endothelin (ET) and calcitonin gene-related peptide (CGRP) in cough variant asthma(CVA) patients, and to investigate their correlation and clinical implications. Methods Thirty CVA patients,30 typical bronchial asthma patients and 25 healthy controls were recruited. Three milliliter limosis venous blood were drawn from each patient to measure the levels of plasma ET and CGRP by radioimmanity. Results ①The levels of ET in the CVA group and typical bronchial asthma group were higher than that in healthy controls (P < 0.01). Their values were (103.58±28.66) ng/L, (129.37±27.28) ng/L and (72.63±21.52)ng/L, respectively. The levels of CGRP in the CVA group and typical bronchial asthma group were (7.62±2.56) ng/L and(6.63±2.09)ng/L The level of CGRP in the healthy controls group was (21.60±3.29) ng/L. The first two groups were lower than the latter(P < 0.01). However, there was no significant difference between the CVA group and typical bronchial asthma group(P >0.05). ②ET and CGRP were negatively correlated in both CVA group(r= -0.819,P<0.05) and typical bronchial asthma group(r= -0.738,P<0.05). Conclusions ET and CGRP were negatively correlated in both CVA group and typical bronchial asthma group, which means that ET and CGRP were a couple of antagonistic factors participated in the regulation of CVA, and may play an important role in the process of CVA.

Objective To observe the effect of duration of carbon dioxide pneumoperitoneum on coagulation, fibrinolysis and endothelial activation in elderly patients undergoing laparoscopic cholecystectomy (LC). Methods The 45 elderly patients with cholelithiasis scheduled for LC, aged over 60 yeas, were placed in different groups respectively after surgery according to the duration of pneumoperitoneum. The duration of pneumoperitoneum was ≤60 minutes in group A (n=21),and more than 60 minutes in group B (n=24). Venous blood samples were taken on admission (baseline), at the end of surgery, the 1st, 2nd and 3rd day after surgery for determination of prothrombin time (PT), activated partial thromboplastin time (APTT), prothrombin fragment F1+2 (F1+2), antithrombin 3 (AT-Ⅲ activity), fibrinogen (Fib), tissue plasminogen activator (t-PA), plasminogen activator inhibitor type-1 (PAI-1), D-dimer (D-D), von Willebrand factor (vWF activity). Results Concerning the coagulation activation, at the 3rd postoperative day, the level of F1+2 was significantly higher in group B than in group A [(1.60±0.26) μg/L vs. (1.32±0.24) μg/L, P＜0.05]; AT-III was significantly higher in group B than in group A [(84.82%±20.21%) vs. (97.49%±16.87%), P＜0.05]. At the 2nd and 3rd postoperative day, the levels of Fib were significantly higher in group B than in group A [(3.87±0.62) g/L vs. (3.42±0.72) g/L, (3.98±0.77) g/L vs. (3.42±0.63) g/L, respectively, P＜0.05]. Concerning fibrinolysis, But at the 2nd and 3rd postoperative day, the level of PAI-1 was significantly higher in group B than in group A [(33.93±10.42) μg/L vs. (26.69±9.49) μg/L, (32.90±11.25) μg/L vs. (26.31±7.06) μg/L respectively, P＜0.05]. Concerning endothelial activation, at the 2nd and 3rd postoperative day, vWF was significantly higher in group B than in group A [(174.53%±44.03%) vs. (134.37%±37.74%), (176.31%±47.6%) vs. (131.21%±36.34%), respectively, P＜0.05]. Conclusions Marked activations of coagulation-fibrinolysis and endothelial activation are observed postoperatively in elderly patients undergoing laparoscopic cholecystectomy. Along with prolonged duration of pneumoperitoneum, more pronounced alterations of increased coagulation, reduced fibrinolysis and endothelial activation are observed, which could constitute an imbalanced situation of coagulation-fibrinolysis and increases the risk of venous thrombosis.

Objective To compare the changes in blood coagulation, fibrinolysis and endothelial damage in patients undergoing laparoscopic cholecystectomy with different durations of carbon dioxide pneumoperitoneum. Methods Sixty-four ASA Ⅰ orⅡpatients, aged 23-60 yr, weighing 45-82 kg, scheduled for elective laparoscopic cholecystectomy, were randomly divided into 3 groups according to the duration of pneumoperitoneum: duration of pneumoperitoneum ≤30 min group (group Ⅰ, n=21), 30 min ＜ duration of pneumoperitoneum ＜ 60 min (group Ⅱ, n=23) and duration of pneumoperitoneum≥ 60 min (group Ⅲ , n=20).The intra-abdominal pressure was maintained at 12-14 mm Hg. Venous blood samples were taken before surgery (baseline, T0 ),at the end of surgery(T1), and at 1, 2 and 3 d after surgery (T2-4) for determination of prothrombin time, activated partial thromboplastin time, concentrations of prothrombin fragment 1+2(F1+2), fibrinogen (Fib), tissue plasminogen activator and plasminogen activator inhibitor type-1 (PAI-1), and activities of antithrombin Ⅲ(AT-Ⅲ)and von Willebrand factor(vWF).Results Compared with groupⅠ , the vWF activity and PAI-1 concentration at T2 , concentrations of Fib, F1+2, PAI-1 and activity of vWF at T3 and concentrations of Fib and F1+2 at T4 were significantly increased, while the AT-IE activity at T3 was significantly decreased in group Ⅲ(P＜0.05) .Conclusion When the duration of pneumoperitoneum is short, no obvious changes in the blood coagulation, fibrinolysis and endothelial damage are observed postoperatively in patients undergoing laparoscopic cholecystectomy, and along with the prolongation of the duration of pneumoperitoneum, increased blood coagulation, reduced fibrinolysisand aggravated endothelial damage are observed postoperatively.

The sagittal and transverse diameters of spinal canal were measured from 344 cases including dry specimens,preserved vertebral colomns and X-ray films.Based on these data several conclusions have been drawn. (1)The morphology of spinal canal is consistent with the external feature of spinal cord. (2)The mean values of various measurement of cervical(C),thoracic(T),and lumbar(L)vertebrae of spinal canal in dry specimens are as follows: Transverse diameter(mm.) Sagittal diameter(mm.) C T L C T L Male 23.6 16.7 23.4 14.4 14.9 16.5 Eemale 23.1 16.1 22.4 13.7 14.2 16.0 (3)The mean values of measurement of spinal canal in X-ray films are as fol- lows: Transverse diameter(mm.) Sagittal diameter(mm.) L C L Male 27.8 16.5 19.8 Female 27.0 15.7 19.1 The data measured from X-ray films are approximately 20% larger than those from the actual specimens. (4)The ratio between the sagittal diameters of the cervical canal and vertebral body is 80～90% in male and 90～100% in female.The normal ratio between the products of sagittal and transverse diameters of the lumbar spinal canal and of the vertebral body is 1:4.Ratios lower than this value is considered to denote a diagnostic significance for spinal stenosis.
