Objective To summary and analysis the clinical experiences on the three hole method of VATS surgery in treatment of primary spontaneous pneumothorax.Methods The clinical data of 276 cases of primary spontaneous pneumothorax undergoing VATS surgery from July 2005 to July 2011 were analyzed retrospectively.Results The operating times were 25 to 76 minutes,averaging (41.7 ± 2.1) minutes ; all with traces of bleeding; transiting assisted small incision operation in 5 cases;postoperative thoracic closed drainage extubation time of 4-13 days,average (6.7 ± 0.2) days,mild postoperative air leakage in 27 cases,moderate in 9 cases without severe leakage,leakage,postoperative pulmonary atelectasis in 7 cases,pulmonary infection in 2 cases,reexpansion pulmonary edema in 1 cases,postoperative follow-up for 6-17 months,averaging(10.2 ± 1.7) months,recurrence occurred in 7 cases,1 case of operation again.Conclusion Three hole method of VATS technique has short operating time,less trauma,fewer complications,faster recovery,shorter hospitalization time and other advantages,and the recurrence rate is low,which is the ideal mode of operation for the treatment of primary spontaneous pneumothorax.

Objective To establish blood reference ranges and compare these ranges with national standard in northeast Sichuan area .Methods Routine blood parameters of red blood cell ,white blood cell ,hemoglobin blood platelet count were detected in 12 480 healthy adult and old persons(divided groups according to gender ,age) and 1 120 neonatal from June 2013 to June 2014 in North Si-chuan Medical College Affiliated Hospital ,and concluded their routine blood reference range ,then analyzed the difference with the national standard .Results The range of red blood cells had no statistical difference compared with national standard in different age and gender groups(P>0 .05) .The ranges of white blood cell count and hemoglobin had significant differences compared with the national standard only in the neonatal group(P<0 .05) .The range of platelet count had significant difference compared with the na-tional standard in all age and gender groups(P<0 .05) in the northeast area of sichuan .Conclusion There are significant differ-ences between the partial routine blood value in the northeast area of Sichuan and the current reference range ,and might influence the clinical judgment of abnormal results .

Objective To investigate the relationship of antithrombin‐Ⅲ activity and thrombosis risk in liver cirrhosis with Child‐Pugh classification .Methods In our hospital from June to December 2014 ,60 liver cirrhosis patients were selected randomly included into this experiment group ,The 60 cases of control group were from medical examination of health in our hospital .The plasma AT‐Ⅲ activity and D‐D concentration in all these cases were detected and analyzed .Results The AT‐Ⅲ in cirrhosis patients were significantly lower than which in healthy persons(P<0 .05) .The lower level of AT‐Ⅲ is in these patients which were in seri‐ous condition(P<0 .05) ,the abnormal rate of D‐D concentration is also higher at the same time(P<0 .05) .Conclusion The detec‐tion of AT‐Ⅲ level in patients with liver cirrhosis is directly related to the severity of clinical and thrombosis risk .The AT‐Ⅲ de‐tection level can be used to judge the patient′s condition and develop appropriate treatment strategies .
