Objective To investigate the effectiveness and feasibility of laparoscopic splenic artery ligation in the treatment of hypersplenism and thrombocytopenia in children. Methods From August 2014 to December 2014, four children with hypersplenism and three children with ITP (idiopathic thrombocytopenic purpura) were treated in our hospital.Laparoscopic splenic artery ligation was performed in all the patients.During the operation, the gastric colon ligament was cut with an ultrasonic knife, and the gastric wall was suspended to expose the pancreas and the spleen.The splenic artery was ligated at the upper edge of pancreas closing to the splenic hilum.The splenic venous branches were dissected and ligated at the splenic hilum by using the Hem-o-lok, which leaded to an area of splenic infarction more than 50%. Results The laparoscopic splenic artery ligation was successfully performed in all the patients, without conversion to open surgery.The operative time was 120-150 min ( mean, 126 min) , and the intraoperative blood loss was 10-20 ml ( mean, 15 ml) .No patient underwent blood transfusion.The length of postoperative hospital stay varied from 4 to 11 days (mean, 6.6 days).The splenic length significantly decreased postoperatively [(13.6 ±2.6) cm vs.(15.1 ±1.7) cm, t=3.199, P=0.049], and so was the splenic thickness [(3.8 ±1.0) cm vs.(4.1 ±0.8) cm, t =3.703, P=0.034].Partial splenic infarction and decreased splenic blood flow were found in the 7 patients by postoperative ultrasound.After surgery, four children suffered from fever, which were 38.8 ℃, 39.0 ℃, 38.6 ℃, and 39.2 ℃, with the duration of fever of 2, 4, 8, and 5 days, respectively.All the patients were followed-up for 6 -10 months (mean, 8.4 months).The complete blood cell count was within normal range. Conclusion The laparoscopic splenic artery ligation is an effective treatment for hypersplenism and thrombocytopenia in children.

To study the effect of different storage conditions and storage time on herb quality of Lonicera macranthoides, different packaging materials including vacuum plastic bags, plastic bags, woven bags, sealed with endometrial bags, paper bags, sack bags were selected for the study under different storage conditions including room temperature, 5 degrees C refrigerator, low temperature of - 20 degrees C refrigerator and desiccator. Twenty-four batches of samples were used for the study, and active ingredients were determined. The experimental results showed that the ingredients in each storage group changed with the storage time, storage conditions (storage environment, packaging). Under the same storage time, the storage environment (temperature, humidity) had effect on the stability of herb quality. Low temperature had less effect on herb quality. The effect of packaging on herb quality was as following: plastic vacuum packaging > woven with endometrial sealed packaging > plastic bag > woven bag > sack bags > paper bags. Under the same storage conditions, with the increase of storage time, caffeic acid content increased slowly, and other five ingredients content decreased gradually. Storage time affected significantly on the intrinsic quality (chemical composition) and appearance of herb. It is suggested that low temperature (5 degrees C), dark and sealed storage are suitable for storage of L. macranthoides herb, the storage time should be not more than 24 months.

Objective To study the effect of papaverine on vasospasm caused by PICC intubation with B-mode ultrasonography. Method Three mg papaverine were injected into the median cubital vein for at least 2 minutes in 15 patients with vasospasm. Results The vasospasm in the 15 patients was relieved 36~270 s seconds after injection. The followed intubation was all successful. There was no abnormality in their liver function and heart rate, or abnormal bleeding, or other serious complications. Conclusion Papaverine can relieve vasospasm caused by PICC intubation, so it can allow another intubation. It also can avoid delayed intubation reduce patients′pain and cost and reduce psychological pressure of the nursing practitioner.

Objective The study evaluated the efficiency and safety of a short-acting full-dose fibfinolytic regimen to promote early infarct-related artery (IRA) patency during the inherent delay experienced by infarction patients referred for angioplasty as the principal recanalization modality. Method Accepted aspirin and heparin, 75 patients were treated by an intravenous bolus of 20 mg recombined tissue-type plasminogen activator (rt-PA), then followed by 80 mg over 30 minutes. Patients were to undergo angiography as soon as possible following study drug.
