ObjectiveTo observe the effect of mometasone furoate on serous eotaxin in children with allergic rhinitis.MethodsThe observation group included 30 cases who got allergic rhinitis and treated by mometasone furoate.The level of eotaxin before and after treatment was detected by ELISA,and was compared with normal children in control group.ResultsBefore treatment,the signs scores of observation group was (9.4 ± 2.3 ),and after treatment was(3.1 ± 1.8),the difference was statistically significant(t =2.148,P ＜0.05).The treatment effect contained 19 cases(63.3％ ) 9 cases(30.0％ ) effective and 2 cases(6.7％ ) ineffective.Before treatment,the level of eotaxin in observation group was remarkably higher than control group [ (221.41 ± 137.96 ) ng/L vs ( 128.71 ± 60.73 ) ng/L,t =- 2.721,P ＜ 0.05 ],after treatment,symptom and sign was mitigated and eotaxin level was remarkably lower than before treatment[ ( 115.50 ± 52.71 ) ng/L vs (221.41 ± 137.96 ) ng/L,t =- 3.661,P ＜ 0.05 ].There was no serious adverse reaction in observation group.ConclusionTreated allergic rhinitis by corticosteroids could inhibit the allergic inflammation and down-regulate the eotaxin level.

Objective To compare the differences of temperature results between mercury thermometer and infrared thermometer. Methods The temperature of three parts was recorded respectively by mercury thermometer in axilla and infrared thermometer in forehead and earlobe on the same patient, totally 98 patients were recorded in ICU. Results There was statistical difference of three parts' temperature in 98 cases. It could be assumed that axilla temperature ＞ earlobe temperature ＞ forehead temperature;There was no statistical difference of three parts' temperature in 17 cases with temperature 38.0～38.9 ℃ by mercury thermometer, but the difference had clinical significance. It could be assumed that axilla temperature ＞ earlobe temperature ＞ forehead temperature; There was statistical difference of three parts' temperature in 30 cases with temperature at 37.0～37.9 ℃ by mercury thermometer. It could be assumed that axilla temperature ＞ earlobe temperature ＞ forehead temperature. There was no statistical difference of three parts'temperature in 51 cases with temperature at 35.0～36.9 ℃ by mercury thermometer. Conclusions Temperature of the patients with normal axilla temperature could be monitored by infrared thermometer instead of mercury thermometer,but it is not applicable to the patients with fever.

Objective To compare the clinical effects of palliative drainage to pancreatic and periampullary carcinoma which could not be excised with the operation.Methotis A retrospective study was accomplished on the palliative drainage treatment of 68 patients with pancreatic and petiampullary carcinoma hospitalized from 1996 to 2003.Results The disease course was two days to eight months.A definite preoperative diagnosis was made for 64 cases.Among them.single test diagnosed 24 cases and multiple tests diagnosed 40 cases.56 patients suffered from jaundice before operation.34 patients were treated by Roux-Y choledochojejunostomy.Choledochoduodenostomy was performed in 16 patients,cholecystduodenostomy for biliary by pass Was performed in 8 patients and stented internal drainage of the biliary duct in the liver and duodenostomy was performed in 10 patients.After reducing jaundice,12 patients was performed surgical resection.The second operation was performed in 4 patients because of postoperative jaundice and in 3 patients because of pylofic obstruction.The pefioperative compllcations include 4 cases of jaundice pyloric,3 cases of obstruction,2 cases of postoperative bleeding and 5 cases of infection of incisional wound.The aver-age stay in hospital waa 13.3 days(8～22 days).Conclusion Multiple tests were helpful to make a definite preoper-ative diagnosis.The selection of palliative drainage method based on the condition of patients had good curative effect in clinic.Surgocal exploration and reducing jaundice could set win conditions for second operation.

Objective To compare patient radiation dose of two techniques of spine X-ray panoramic imaging under the same image quality.Methods An anthropomorphic phantom was used.The reasonable imaging parameters were found for spine panoramic radiography using Sonialvision safire17 Slot scan with HQ mode.And the panoramic films were obtained with different parameters using GE XR650 DR system.The panoramic images were scored by three experienced radiologists.The imaging parameters with the same score in groups were input into PCXMC 2.0 software to get effective dose(E) and organ dose.Results The reasonable imaging parameters of Slot scan were high quality(HQ) mode, SID 150 cm, 100 kVp, and 2 mAs;and the corresponding parameters of XR650 were SID 200 cm, 100 kVp, and 3.2 mAs.The E of the Slot scan with HQ mode, XR650 with manual mode and XR650 with AEC mode was(0.118 7±0.001 4),(0.0847±0.0008), and (0.1580±0.001 5) mSvrespectively, while the E of XR650 with manual mode was lower than the others(F =3 007.293, P ＜0.05).The organ dose using XR650 DR with manual mode were lower than that using Slot scan with HQ mode in all samples except breasts(P ＜0.05);the organ dose using XR650 DR with AEC mode were higher than that using XR650 DR with manual mode and Slot scan with HQ mode for all samples except for thyroid, oesophagus and lungs (P ＜0.05).Conclusions The radiation doses of both spine X-ray panoramic imaging with manual mode are low, and low dose spine X-ray panoramic imaging can be achieved if reasonable parameters are used.

Objective To investigate the method of surgical treatment of acute intestinal obstruction caused by colorectal cancer,and affirm the feasibility and validity of the new way ofearly precolonic postoperative enteral nutritionafter operation of acute intestinal obstruction caused by colorectal cancer.Methods Retrospective analized the clinical data of 78 cases of acute intestinal obstruction caused by colorectal caner from September 2007 to September 2012 and the incidence of complications (incision infection,intra-abdominal abscess,anastomotic leakage,and pneumonia) was observed.Results Sixty-two patients received radical resection and primary anastomosis.All of them were cured and no death occurred.Two patients had complication of postoperative infection and none suffered from anastomotic or drainage leakage.Conclusion Radical resection and primary anastomosis using Intra-operative colonic lavage are safe and effective methods for patients with colorectal cancer associated with acute intestinal obstruction,and early precolonic postoperative enteral nutritioncould better eliminate perioperative malnourished patients more,reduce operation complication,prevent anastomotic leakage,and increase the success rate of the operation.

Objective To explore ICSI treatment process in the different proportion of oocytes maturation and dosage of gonadotropin affecting embryo quality and clinical outcome. Methods From Jan. to Dec. 2015,we retrospectively analyzed the patients from the center line of ICSI cycle ,divided them into three groups according to the maturity of oocytes. The 3 groups were due to maturity rate of oocytes in 50% in group A(n = 19),50% 0.05). Group A had the best egg rate,high quality embryo rate,clinical pregnancy rate than the other two groups (P < 0.05). In pregnancy and non-pregnancy groups ,the dosage of gonadotropin in the non-pregnancy group was obviously higher than that in the pregnancy group in oocyte maturation in the same proportion interval(P<0.05). Conclusion In ICSI treatment process,the high dose of gonadotropin and rising rates of oocytes maturation are not conducive to the development potential of the egg and clinical outcome,so the dose of gonadotropin and oocyte maturation ratio should be controlled in a certain range to collect and protect the best dominant egg which matches to the state of the patient.
