1.Design and application of self-made water pillow
Modern Clinical Nursing 2014;(7):85-87
Objective To explore the effect of self-made water pillow on absolute bed rest patients.Methods Eight-eight patients were randomly allocated into observation group(n=46)and control group(n=42).The patients in the control group received daily care with conventional cotton pillows which were placed at the compression part, while those in the observation group were treated with newly designed water pillows.Both groups received constant turn-over to avoid pressure sores.The two groups were compared in terms of times of daily turn-over,degree of comfort and rate of skin pressuring red.Results The time of daily turn-over in the observation group was less than that of the control group and the degree of comfort was higher and the rate of skin pressuring red smaller all with statistically significant differences(P<0.05).Conclusion The application of the self-made water pillow can effectively prevent pressure sore,enhance comfort degree of absolute bed rest patients and reduce the workload of nursery.It is simple, economical,convenient and safe.

International Journal of Pediatrics 2016;43(4):317-321
Objective To explore the effects of prenatal infection on the development of lungs by dynamic observation of morphology and numbers of inflammatory cells in lungs of rat pups exposed to antenatal inflammation.Methods Pregnant Wistar rats were randomly divided into experimental group and control group.Pregnant rats of both groups were intraperitoneal injected with either lipopolysaccharide (LPS) 2.5mg/kg or the same volume of normal saline on embryonic day 19 and 20, respectively, and were allowed to term deliver.Onday1, 3, 7, 14, 21and28 (D1, D3, D7, D14, D21 andD28), eight pups of each group were killed by 10% chloral hydrate (1ml/kg) and lungs were collected.The numbers of myeloperoxidase (MPO) and CD68 as markers of both neutrophils and macrophages were counted.Morphometric assessments were performed by measuring the mean numbers of alveolar, the mean ratio of alveolar surface area to per tissue and the mean thickness of alveolar septum.Results With the increasing of postnatal days, the mean numbers of alveolar and the mean ratio of alveolar surface area to per tissue in both groups increased.The mean thickness of alveolar septum got thinner and the numbers of inflammatory cells decreased.On D1, D3, D7 and D14, the mean alveolar numbers of the experimental group (88, 89, 102 and 127 /mm2) were significantly less than those of the control group (105, 109, 123, 156/mm2), P =0.024, 0.009, 0.013, 0.004, respectively.On D1, D3 and D7, the mean ratios of alveolar surface area to per tissue were significantly larger (0.552,0.603 and0.533) than those of control group (0.478, 0.485 and 0.404), P=0.003, 0.001, 0.000, respectively.On D1 and D3, the alveolar septum thickness was significantly thinner (12.30 and 10.75 μm) thanthatin control group (17.13 and 16.13 μm), P=0.000, 0.000, respectively.On D1, D3, D7 and D14, the mean numbers of neutrophils of the experimental group (681, 582, 393 and 379/mm2) were significantly more than those of control group (164, 211, 145 and 179 /mm2), P =0.000, 0.000, 0.000,0.003, respectively.On D1, D3 and D7, the mean numbers of macrophages (613, 578 and 337 /mm2)were significantly more than those of control group (170, 182 and 127, /mm2) , P=0.000, 0.000, 0.000,respectively.Conclusion Prenatal infection results in larger and fewer alveolars and more inflammatory cells in lungs of rat pups.With the increasing of postnatal days, the alveolar morphology was similar to the controis.
6.Treatment of pancreatic neuroendocrine tumor with liver metastases
Journal of Clinical Hepatology 2015;31(5):668-670
Pancreatic neuroendocrine tumor (pNET)is a rare type of pancreatic tumors.The incidence of pNET shows a gradually increas-ing trend in recent years.The most common organ of distant metastases is the liver.Surgical resection is still the optimal treatment for resect-able,well -differentiated liver metastases with no evidence of extrahepatic spread.For unresectable patients,a combination of multiple mo-dalities,such as transarterial chemoembolization,radiofrequency ablation,systemic chemotherapy,and molecular targeted therapy,can pro-long the survival time of patients.Liver transplantation should be strictly evaluated on an individual basis.

China Oncology 2016;26(5):367-371
With the development of surgical techniques, the use of nipple-areola complex (NAC)-sparing mastectomy (NSM) has been increasing. Except for oncologic safety, the aesthetic outcome of surgery is greatly concerned by clinicians and patients. So far, there has been no consensus on the incision of NSM. This article reviewed the literature so as to provide some evidence for the selection of NSM incision.

10.Effects of different ventilations during the induction of anesthesia on postoperative nausea and ;vomiting in patients undergoing laparoscopic cholecystectomy
Chinese Journal of Postgraduates of Medicine 2016;39(5):453-456
Objective To investigate the effects of different ventilations during the induction of anesthesia on postoperative nausea and vomiting in patients undergoning laparoscopic cholecystectomy. Methods One hundred and twenty patients undergoing laparoscopic cholecystectomy were randomly divided into M group and V group according to random number table, 60 patients each group. The patients in M group performed manual ventilation and the patients in V group performed mechanical ventilation. According to different tidal volume, V group were randomly divided into three groups (20 patients each group:V1,V2 and V3 group, respectively recieved body weight × 4, 6 and 8 ml/kg. After tracheal intubation,the operations were completed by maintaining the end of CO2 partial pressure (PETCO2)from 35 to 45 mmHg, 1 mmHg = 0.133 kPa. Tidal volume, peak airway pressure (Ppeak) and PETCO2 in anesthesia induction,and intraoperative gastric insufflation and postoperative nausea and vomiting were recorded and compared. Results The incidence rate of gastric insufflation, postoperative nausea and vomiting in V group were significantly higher than those in M group:50.0%(30/60) vs. 21.7%(13/60), 45.0%(27/60) vs. 18.3%(11/60), 26.7%(16/60) vs. 10.0%(6/60), P<0.05. The level of Ppeak in M group, V2 group and V3 group were signicantly higher than that in V1 group: (13.55 ± 1.95), (12.05 ± 1.23), (18.35 ± 3.71) cmH2O vs. (13.55 ± 1.95) cmH2O, 1 cmH2O = 0.098 kPa, P<0.05. The level of PETCO2 in M group, V2 group and V3 group were signicantly lower than that in V1 group:(19.60 ± 4.31), (27.75 ± 1.94), (23.60 ± 4.45) mmHg vs. (29.90 ± 2.40) mmHg, P<0.05. Conclusions Manual ventilation during the induction of anesthesia in patients undergoning laparoscopic cholecystectomy is better than mechanical ventilation . Proper manual positive pressure ventilation and volume mechanical ventilation with low tidal (4 ml/kg) may allow for decreasing intraoperative gastric insufflation and postoperative nausea and vomiting.
