Excimer laser was found in 1975, and has been used in corneal refractive surgery, which made a great progress and become rapidly developed. ArF laser of 193 nm has high accuracy because it can gasify corneal tissue molecule. Moreover, it does not produce heat effect on tissues surrounding irradiated sites, so not produce adverse effect on corneal structure. At present, excimer laser has been successfully used in corneal radial incision, excimer laser corneal refractive surgery, laser in situ keratomileusis, laser epithelial keratomileusis and laser subepithelial keratomileusis. With increasing understanding of excimer laser and accumulating clinical experience, novel, accurate and predictive excimer laser corneal refractive surgery will be developed.

ObjectiveTo investigate the clinical features of intramedullary spinal cord tumors(IMSCT) in children.MethodsThe clinical data including sex,age,pathohistology,clinical manifestations and medical check-up collected from 16 children diagnosed as IMSCT in Shengjing Hospital Affiliated to China Medical University,were retrospectively reviewed and analyzed.ResultsThe study subjects inclu-ded 11 male and 5 female,with an average age of(8.55?4.28) years old,ranged from 15 months to 14 years old.The interval lasted 1 day to 9 years from onset of the syndrome to confirmed diagnosis of IMSCT.The first clinical manifestation was mostly pain.The main clinical mani-festations included limb dyskinesia in 14 cases,pain in 12 cases,urine and stool disturbance in 9 cases,gait irregularity in 8 cases,extremity atrophy in 3 cases.Medical check-up included abnormal tendon reflex in 14 cases,abnormal superficial reflex in 9 cases,sphincter dilatation in 6 cases,positive Babinski's signs in 5 cases,spinal deformity in 4 cases,region masses in 3 cases,paraesthesia in 2 cases,inequality of lower limb in 1 case,dermai sinus in 1 case,pigmentation in 1 case.The cases were evaluated by magnetic resonance imaging,which presented thickened spinal cord and intramedullary abnormal signals in all the cases.Pathological types: teratoma in 5 cases,dermoid cysts in 2 cases,epidermoid cyst in 2 cases.Misdiagnoses included urinary tract infections in 2 cases,rheumatoid arthritis in 1 case,and lumbar disc protrusion in 1 case.ConclusionsThe main pathohistology of pediatric IMSCT is congenital tumor.First clinical manifestation is pain.MRI can show a reliable evidence for the diagnosis.It is important to improve the outcomes of pediatric IMSCT by establishing the diagnosis and administering proper management as early as possible.

Objective To explore the role of procalcitonin(PCT)in antibiotics therapy of elder patients with community acquired pneumonia(CAP). Methods Sixty-two elderly patients with CAP who hospitalized in Linxi Hospital of Kailuan General Hospital from Jan. 2010 to Dec. 2013 were selected as study subjects,and their age span were 54. 0 - 87. 0 years old. All the patients were randomly divided into conventional therapy group(n= 33)and PCT group(n = 29). The use of nntibiotics in conventional treatment group was based on clinical symptoms of patients and the standard of antibiotics application in clinic,while in PCT group was based on PCT serum levels. The main observation indexes including days of antibiotics use,cost of antibiotics use,hospital stay, total cost of hospital stay,clinical efficacy,aggravating cases and death cases. Results The days of antibiotics use,cost of antibiotics use,hospital stay,total cost of hospital stay in PCT group were((12. 2 ± 1. 4)d, (3 341. 9 ± 52. 73)yuan,(12. 1 ± 1. 8)d,(5 346. 2 ± 1 274. 5)yuan)lower than that in conventional therapy group((16. 9 ± 3. 5)d,(3 816. 28 ± 84. 27)yuan,(14. 7 ± 2. 9)d,(6 653. 2 ± 1 132. 8)yuan),and the differences were significant(t = 6. 77,26. 14,4. 17,4. 28;P < 0. 001). There were no significant difference in terms of clinical prognosis( clinical efficacy,aggravating cases and death cases)( P > 0. 05).

OBJECTIVE:To investigate the effects of erythropoietin (EPO) combined with hyperbaric oxygen on neurologic function recovery and cerebral tissue metabolism of hypoxic-ischemic encephalopathy (HIE). METHODS:A total of 47 HIE neo-nates in our hospital during Sept. 2012-Apr. 2015 were selected and divided into observation group (25 cases) and control group (22 cases)according to random number table. Both groups received routine symptomatic supportive treatment as reducing intracrani-al pressure,correcting acidosis,maintaining electrolyte balance and controlling seizures. Control group was given hyperbaric oxy-gen therapy,compressing 15 min,inhaling 30 min,decompressing 15 min,qd. Observation group was additionally given rhEPO injection(CHO cell)200 U/kg,subcutaneously at the first time,intravenous injection from the second time,qd. Both groups were treated for consecutive 10 d. NBNA score,neural reflex recovery time,consciousness recovery time,the serum levels of NSE, MBP and S100B protein were observed in 2 groups before and after treatment. The occurrence of ADR was recorded. RESULTS:Before treatment,there was no statistical significance in NBNA score,serum levels of NSE,MBP and S100B protein between 2 groups (P>0.05). Five and ten days after treatment,NBNA scores of 2 groups were increased significantly compared to before treatment,and the observation group was significantly higher than the control group at corresponding period,with statistical signifi-cance (P<0.05). The serum levels of NSE and S100B protein in 2 groups were decreased significantly compared to before treat-ment,and the observation group was significantly lower than control group at corresponding period,with statistical significance (P<0.05). After 5 days of treatment,serum levels of MBP in 2 groups were increased significantly compared to before treatment, with statistical significance(P<0.05),but there was no statistical significance between 2 groups(P>0.05). After 10 days of treat-ment,serum levels of MBP in 2 groups were decreased significantly,and the observation group was significantly lower than con-trol group,with statistical significance (P<0.05). After treat-ment,neural reflex recovery time and consciousness recovery time of observation group were significantly shorter than con-trol group,with statistical significance (P<0.05). There was no statistical significance in the incidence of ADR between observation group (8.00%) and control group (9.09%)(P>0.05). CONCLUSIONS:For HIE neonates,EPO combined with hyperbaric oxygen can effectively promote neurologic function recovery and cerebral tissue metabolism with good safety.
