Objective To explore the diagnosis and treatment of closed abdominal injuries in infants.Methods A retrospectively analysis of the clinical data of 84 infants with closed abdominal injury was made.Results Among the 84 cases, 60 cases had closed parenchymal visceral injury (32 cases of liver and 28 cases of spleen), 10 cases had small intestine perforation, and 14 cases had soft tissue contusion of abdominal wall. Non-operative treatment was used in 27 cases of liver injury and 22 cases of splenic injury, operative treatment in 5 cases of liver injury and 6 cases of splenic injury, and operative treatment for the 10 cases of other types of injury. All the 84 infant patients were cured.Conclusions In diagnosis and treatment of closed abdominal injuries in infants, abdominal centesis, type-B ultrasound and CT should be rationally chosen and applied in order to quickly determine location and extent of visceral injury; indications for operation should be under strict control. Non-operative treatment of parenchymal visceral injury of infants is proved to be safe and with a high cure rate.

The linear range of chlorine alcohol was 16.11-96.65 μg·ml-1(r=0.999 7), the average recovery was 97. 8% (RSD=2. 1, n=9), and the detection limit was 0. 62 ng. The linear range of pyridine was 15. 87-95. 23 μg·ml-1(r=0. 999 8), the average recovery was 99. 2% (RSD=1. 3, n=9), and the detection limit was 0. 15 ng. Con-clusion:The method is reliable, simple, accurate and stable, and suitable for the determination of benzene, chlorine alcohol and pyri-dine residues in piperazine ferulate.

Objective:To establish an HPLC method for the determination of related substances in piperazine ferulate. Methods:An HPLC method was used to determine the related substances in piperazine ferulate. The separation was performed on an Xtimate C18 column (250 mm × 4. 6 mm, 5 μm). The mobile phase was 0. 5% acetic acid-methanol-acetonitrile with gradient elution. The flow rate was 1. 0 ml·min-1 and the column temperature was 30℃. The detection wavelength was 286 nm and the injection volume was 20μl. Results:Ferulic acid had a good linear relationship within the range of 5-30 μg·ml-1(r=1.0000). The detection limit was 0. 02 ng. Conclusion:The method is reliable, simple, accurate, stable and durable, and suitable for the determination of related sub-stances in piperazine ferulate.

Objective To evaluate the performance of parallel test in detecting malaria infection for returned person from malaria endemic area.Methods The blood samples of 484 returnees from malaria endemic area were analyzed and detected by thick blood smear,rapid diagnostic test (RDT) and nest PCR in four companies involving the African labor dispatching.Results The sensitivi ty of thick blood smear and RDT was 0.628 and 0.744 respectively,which of the parallel test was 0.930.On the other hand,the area under the curve (AUC) of parallel test was 0.930 (95％CI:0.895-0.986),which was higher than thick blood smear[0.814 (95％CI:0.724-0.904)]and RDT[0.847 (95％CI:0.769-0.926)].Conclusion Thick blood smear and RDT,which consist of parallel test,could improve the detection sensitivity and accuracy for returnees from malaria epidemical area effectively.This approach is worthy of popularization and application.

AIM: Recent studies have identified the importance of inflammation in the development and progression of heart failure.Chemokines are essential factors in the recruitment and activation of leukocytes.They are closely related with inflammation.So the relation between chemokines expression and lymphocytes recruitment and cardiac function after acute myocardial infarction(AMI) was studied.METHODS: Ligating left interventricular branch induced AMI.Experimental rats were divided into three groups: heart failure group(MI-HF),non-heart failure group(MI-NF) and sham group(sham).Sham group was made by the same procedure only without ligation.The blood dynamics of rats was examined after 3 days,1 week and 2 weeks following ligation.Rats,which had a left ventricular end-diastolic pressure(LVEDP) above 15 mmHg,were considered to be in heart failure.Reverse transcription polymerase chain reaction(RT-PCR) was used to analyze the mRNA expression of chemokines,including monokine induced by IFN-?(MIG),macrophage inflammatory protein-1 alpha(MIP-1?) and regulated upon activation,normal T cell expressed and secreted(RANTES),in the infarcted region(circumjacent region included).The numbers of lymphocytes infiltrated in the infarcted region were also counted.RESULTS: MIP-1?,RANTES and MIG mRNA increased at 3 days and reached the peak at 1 week after AMI,significantly higher in MI-HF group than those in MI-NF group(RANTES,0.83?0.05 vs 0.51?0.19,P

AIM: To discuss the effect of Smart Plug canalicular plug on aqueous-deficient dryeye.
METHODS:Forty-eight cases of aqueous-deficient dry eye patients in our hospital from May 2012 to April 2013 were selected for the study. After treated by Smart Plug canalicular plug, postoperative clinical efficacy, foundation Schirmer I test ( SIt) , tear film break-up time ( BUT ) , corneal fluorescein staining ( FL ) changes were observed.
RESULTS: Forty-eight patients were cured, 31 cases were markedly effective(65%), effective 14 cases (29%), invalid in 3 cases (6%), the total effective rate was 94%. Before treatment, SⅠt, BUT, and FL was ( 3. 49±1. 24 ) mm/5min, ( 3. 15±1. 07 ) s, and ( 2. 52±0. 11 ) points, respectively. After treatment, SIt, BUT, FL were significantly improved compared with before treatment, the difference was statistically significant (P<0. 05). One patient had postoperative foreign body sensation, 8h after shedding emboli; One patient granulation tissue after surgery 8mo, canalicular plug off. The remaining cases had no inferior lacrimal duct infection or granuloma.
CONCLUSION: Smart Plug canalicular plug is an effective treatment for aqueous-deficient dry eye, can effectively relieve symptoms, worthy of promotion.

AIM:To observe the transplantation of acellular porcine corneal stroma on the treatment of superficial keratitis by drug-resistant fungal.METHODS:We performed a retrospective analysis of 16 cases of fungal keratitis received the transplantation of acellular porcine corneal matrix from June 2015 to March 2016 with a follow-up of 6mo.We analyzed on items as postoperative visual acuity, corneal graft status, postoperative recurrence and postoperative complications.RESULTS:We observed a healing time of corneal epithelium in 7 to 10d postoperatively generally and the absence of corneal edema in 1mo, while the cornea gradually returned transparent in the 16 cases.Two cases required medication for an epithelial recovery and 3 cases received intervention for decreasing intraocular pressure to a certain level.During the follow-up we observed no cases of cornea degeneration, recurrence of infection or rejection.The vision acuity showed 1.27±0.22, 1.11±0.13, 0.79±0.22 in 1, 3 and 6mo after operation respectively.There was no statistical difference between vision in 1mo and the vision before surgery (P=0.06);while we found a statistical difference when comparing the vision of 3 and 6mo with vision before surgery (P=0.01,0.001).The vision in 6mo increased with a statistic difference to the vision at 1 and 3mo (P<0.001) while no statistic difference was observed between 1 and 3mo(P=0.11).CONCLUSION:Transplantation of acellular porcine corneal matrix is a safe and efficient treatment for fungal keratitis.
