Objective To learn the effect of individualized nutritional support in the treatment of severe acute pancreatitis and provide an effective nutritional support therapy for the disease.Methods 97 patients of severe acute pancreatitis were randomly divided into 51 cases of observation group and 46 cases of control group.The control group was given standard parenteral nutrition.The observation group was given the same heat and support stage of individual nutrition nitrogen.Hemoglobin (Hb),albumin (ALB),pre albumin (PA)and transferrin (TFN)of the two groups were detected before and after treatment.The recovery time of serum amylase,resumed oral intake time, hospitalization time and hospitalization expenses of the two groups were observed.The occurrence of gastrointestinal complications was observed in the two groups during the treatment period.Results Compared with before treatment, after treatment Hb,ALB,PA,TFN of the two groups were significantly increased (t =4.114,7.540,5.556,8.307 and 1.994,3.970,2.906,5.099,all P <0.05).After treatment,ALB,PA,TFN of the observation group were higher than the control group (t =2.249,2.256,3.630,all P <0.05).After treatment,recovery time of serum amylase,resumed oral intake time,hospitalization time and hospitalization expenses of the observation group were lower than the control group (t =3.191,5.245,4.846,8.762,all P <0.05).The incidence rate of gastrointestinal complications of the observation group was 11.8%(6 /51),and that of the control group was 15.2%(7 /46),the difference was not statis-tically significant (χ2 =0.248,P >0.05).Conclusion In the treatment of severe acute pancreatitis,individualized nutritional support has better curative effect,low incidence of complications,with good clinical application value.

AIM:To examine the efficacy and safety of cryotherapy in the management of Fusarium corneal ulcer.
METHODS: Retrospective contract analysis of the clinical data of 41 patients ( 41 eyes ) who infected with Fusarium corneal ulcer. All of them underwent focal lesion keratectomy combined with amniotic membrane transplantation between January 2010 and May 2013. The cryotherapy treatment group of 22 cases (22 eyes), non-cryotherapy group of 19 cases ( 19 eyes ) . All the cases were followed up for 3 ~12mo. We analyzed the healing of corneal ulcer, corneal neovascularization, postoperative visual acuity, complications and ulcer recurrences.
RESULTS: There were no significant difference for the two groups at the cure rate and the recovery rate, the corneal neovascularization and postoperative visual acuity (P>0. 05). The total effective rate and corneal healing time in cryotherapy group was significantly higher than that in non - cryotherapy group ( P < 0. 05 ). The postoperative visual acuity of two group were higher than that of preoperatively ( P < 0. 05 ). There was no complication occurred in cryotherapy group while there was 1 patient of secondary glaucoma in non-cryotherapy group.
CONCLUSION: Cryotherapy is an effective and safe method for the treatment of Fusarium corneal ulcer.

OBJECTIVETo investigate the role of mitochondrial calcium uniporter in cardioprotection elicited by ischemic postconditioning (Postcond).

METHODSMale Sprague-Dawley rats were used for Langendorff isolated heart perfusion. The hearts subjected to global ischemia for 30 min followed by 120 min of reperfusion. Left ventricular developed pressure (LVDP), maximal rise/fall rate of left ventricular pressure (± dP/dtmax) were measured. The level of lactate dehydrogenase (LDH) in the coronary effluent was measured spectrophotometrically, the content of formazan of myocardium was also measured at the end of reperfusion.

RESULTCompared to I/R group, Postcond had an significant increase in the mechanical function of the left ventricle, with LDH release reduced and the content of formazan increased. Spermine, the opener of mitochondrial calcium uniporter, deteriorated the mechanical function of left ventricle and decreased the formazan content, and increased LDH release. Ruthenium red, the inhibitor of mitochondrial calcium uniporter, increased the mechanical function of the left ventricle, decreased the LDH release, but the content of formazan was not increased.

CONCLUSIONThe inhibition of mitochondrial calcium uniporter is involved in the mechanisms of ischemic postconditioning.
