Phase-contrast magnetic resonance imaging (PC-MRI) is a valuable and noninvasive method for evaluating hemodynamics and assessing the severity of disease processes involving the cardiovascular system. The basical principles, influential factors and the applications of PC-MRI in the assessment of cardiovascular diseases were reviewed in this paper.

Objective To explore the the effect of Omeprazole combined with operation on treatment of rupture of small intestine in closed abdominal injury.Methods From June 2014 to December 2014,64 cases in Xinchang county people's hospitalwith rupture of small intestine in closed abdominal were divided into the treatment group and the control group,32 cases in each group.The control group were treat with surgery,the treatment group were given surgery combined with Omeprazole.The total effective rate,quality of life,the recovery time of bowel sound and the echaust time in the two groups were compared.Results The total effective rate(90.6％,29/32)in the treatment group was significantly higher than that in thecontrol group(75.0％,24/32),the difference is significant(P< 0.05).The life index in the treatment group is significantly better than that in the control group(P<0.05).The recovery time of bowel sound in the treatment group(15.3±2.6)h,is shorter than that in the control group(23.8±6.8)h; the exhaust time(23.6±2.2)h in the treatment group is lower than that in the control group(32.3±4.6)h,the differencesis statistically significant(P< 0.05).Conclusion It can significantly improve the effect and postoperative indexes which omeprazole combined with surgical treatment on the treatment of rupture of small intestine in closed abdominal injury,Itshould be widely promoted.

Objective To compare the different operation routes of laparoscopic right hemicolectomy (up‐to‐down vs.medial‐to‐lateral dissection sequences ).Methods In total ,56 cases enrolled in the Central Hospital of Wuhan between Janu‐ary 2013 and January 2014 were randomly divided into the up‐to‐down group and medial‐to‐lateral group.Statistical data in terms of general information ,operation time ,blood loss ,rate of conversion to open surgery ,number of lymph nodes harvested , postoperative complications ,time to first bowel movement and hospital stay time were compared and analyzed.Results The up‐to‐down group has the advantages of shorter operation time [(128.24 ± 21.14) min vs.(166.45 ± 30.23) min ,P<0.01] ,lower conversion rate(0% vs.7.14% ,P=0.035)and less blood loss= [(45.67 ± 10.66) mL vs.(78.45 ± 40.28) mL ,P<0.01] than the medial‐to‐lateral group.However ,there were no significant differences in terms of general information ,number of lymph nodes harvested ,rate of postoperative complications ,time to first bowel movement and hospital stay time (all P>0.05) .Conclu‐sion Taking the superiority of broad perspective ,clear image ,safety and less blood loss into consideration ,the up‐to‐down op‐eration route of laparoscopic right hemicolectomy deserves clinical recommendation.

Objective To emphasize the importance of establishing the efficient scientific archives management of measuring appliance for the hospitals' modern construction in the present situation.Methods Integrated archives of measuring appliances were established and the organization of hospital-metrology-management archives was completed.Results The effect of measuring appliance archives management was exerted adequately.A reliable safeguard was offered to promote the quality of medical treatment and decrease the medical litigation.Conclusion The establishment of effective scientific archives management of measuring appliance has an important influence in promoting the quality of medical treatment and enhancing the safety.

Objective:To evaluate the utilization of antifungal drugs in Nanjing area, and provide clinical reference for the rational use of antifungal drugs. Methods:According to the sales data of antifungal drugs in 34 hospitals in Nanjing area from 2013 to 2015, the utilization of antifungal drugs was analyzed in respects of consumption sum, DDDs and DDC. Results:The consumption sum and use of antifungal drugs increased year by year. The maximum amount of consumption sum growth rate was 41. 13%. Triazole drugs oc-cupied the top of consumption sum during the past three years, and the sales amount accounted for more than 60% of all. In term of consumption sum, voriconazole, fluconazole, itraconazole and caspofungin ranked top 4 of antifungal drugs. Clotrimazole topical prepa-rations and oral itraconazole ranked top 2 of DDDs, and caspofungin, micafungin and voriconazole ranked top 3 of DDC. Conclusion:The clinical application of antifungal drugs continues to increase during 2013 and 2015. Invasive fungal infection is a lethal factor at high risk. Choosing reasonable, effective, safe and economic of antifungal drugs is the first principle in clinical treatment.

AIM: To investigate the change of corrected vision and stereo vision in anisometropic patients after laser in situ keratomileusis (LASIK).METHODS: The clinical data of 84 cases of anisometropic children(84 eyes) were retrospective analyzed.The changes of corrected visual acuity and stereopsis of different gender,age,type of amblyopia in children anisometropic before treatment,after treatment for 3,6mo and 1a were analyzed.The stereoscopic vision correction correlation were analyzed.RESULTS: Corrected Log MAR visual acuity and stereopsis of 84 patients after LASIK surgery treatment for 3mo,and 1a later significantly decreased than before treatment (P<0.05).The corrected Log MAR visual acuity and stereopsis of male and female after treatment for 3,6mo and 1a was not statistically significant (P>0.05).Corrected visual acuity of age <30 group for 3,6mo and 1a was significantly lower than the age ≥30 group (P<0.05).After 3,6mo and 1a stereo vision with hyperopic anisometropia amblyopia decreased more than that with myopic anisometropia amblyopia(P<0.05),but corrected Log MAR visual acuity after treatment was no statistically significant difference (P>0.05).Improved correctted vision of anisometropic patients after LASIK surgery had no connection with the decrease of stereo vision(P>0.05).CONCLUSION: LASIK surgery can improve visual acuity in patients with anisometropia amblyopia,but the course of treatment of visual acuity and stereopsis affected by age and type of amblyopia.

AlM:To evaluate the effect of intralamellar cryolysis of cornea with amniotic membrane transplantation on painful bullous keratopathy ( PBK) .?METHODS: Randomly selected 156 cases ( 156 eyes ) with PBK who underwent surgery of intralamellar cryolysis of cornea with amniotic membrane transplantation. Followed up with 2 ~ 3mo, the symptoms of eye pain, corneal epithelial blisters, foreign body sensation and postoperative complications were observed.?RESULTS:Pain symptoms disappeared in all patients, and corneal epithelial blisters disappeared in 130 cases (83. 3%). All agonizing pain symptoms disappeared, but patients had occasional foreign - body sensation, occasional corneal epithelial blisters in 24 cases ( 15. 4%) . Two weeks after surgery, corneal stroma dissolved, 2 cases ( 1. 3%) of them were cured by conjunctival flap cover.?CONCLUSlON:The operation of intralamellar cryolysis of cornea with amniotic membrane transplantation can relieve the pain in 98. 7% of PBK patients and simple therapy for treating PBK. Hence, it's be worth to advocate for relieve the pain of patients.

Objective To investigate the possible origin and role of follistatin (FS) in pregnancy Methods The maternal serum FS levels in menstrual cycle, first trimester (8～12 weeks) and term (38～41 weeks) were determined by a specific two site enzyme linked immunosorbent assay (ELISA). Reverse transcription polymerase chain reaction (RT PCR) method was utilized to semi quantitatively determine FS mRNA levels in the ovaries and placentas Results Maternal serum FS level at term was significantly higher than that in the first trimester of pregnancy and that in normal women during the menstrual cycle(180?26)?g/L ,(4.4?2.1)?g/L, (1.5?2.2)?g/L , (respectively P
