ObjectiveTo investigate the changes of serum myocardial enzymes and high density lipoprotein cholesterol(HDL-C) in children with septic shock.MethodsFifty-two children with septic shock in our hospital from Jan 2006 to Mar 2011 were divided into severe septic shock group( n =27 ) and mild septic shock group ( n =25 ).The serum creatine kinase-MB ( CK-MB ),α-hydroxybutyrate dehydrogenase (α-HBDH),lactic dehydrogenase(LDH) and HDL-C were analysed in both two groups on 1,2,4,7,10,15 d,and compared with 32 normal children as control group.Meanwhile,the children's condition,death cases and cured time were recorded.ResultsThe levels of serum CK-MB [ ( 32.084 ± 4.595 ) U/L,( 61.481 ±5.639) U/L],α-HBDH/LDH(0.694 ±0.080,0.884 ±0.079) in mild and severe septic shock groups were higher than those of normal control group[ (21.675 ± 3.453) U/L ] and (0.443 ± 0.065 ) ( P ＜ 0.01 ) ;the levels of serum HDL-C[ (0.646 ±0.067) mmol/L,(0.310 ± 0.124) mmol/L ] in the two septic shock groups were decreased significantly than that of control group[ ( 1.012 ±0.156) mmol/L] (P ＜0.01 ).Five cases died in the severe septic shock group while no cases died in mild septic shock group.The times of CK-MB recovered[ (9.82 ±1.76) d vs (4.68 ± 1.22) d],α-HBDH/LDH recovered[ (7.23 ± 1.38) d vs (3.76 ± 0.83 ) d] and HDL recovered[ ( 12.14 ± 2.21 ) d vs ( 6.48 ± 1.33 ) d ] were more slowly in severe septic shock group than those of mild septic shock group( P ＜ 0.01 ).ConclusionThe higher of the serum CK-MB and α-HBDH/LDH,and the lower of HDL-C in septic shock children,the disease is more severe,the recovery time is longer and a worse prognosis may occur.

Spermiogenesis is a complex process of differentiation and morphologic alteration, in which sperm acrosome formation is an important stage. Acrosome is an essential component of the sperm head, which develops in four distinct phases: Golgi, cap, acro- somal, and maturation, each supported by precise and orderly regulation of various genes. The regulatory genes which act on Golgi ap- paratus include GOPC, Hrb, SPATA16, PICK1, and CK2α', those involved in the cap phase are Fads2, syntaxin 2, Kdm3a, and UBR7, and participating in acrosomal and maturation phases are KIFC1, Rnf19a, and DPY19L2. The abnormalities of these genes may affect male fertility by influencing the connection of the nuclear dense lamina and acroplaxome with the nuclear membrane and then the fusion and transportation of vesicles. This review focuses on the genes involved in different phases of acrosome formation.

Coronary artery disease (CAD) is one of the leading causes of death. Safflower attracts great attention owing to its anti-ischemia/reperfusion injury effect. Ninety-three patients with CAD were included and randomized into safflower treatment group, PCI group and control group. Low-dose dobutamine stress echocardiography (DSE) was performed to measure end-systolic volume (ESV), end-diastolic volume (EDV), left ventricular ejection fraction (LVEF) and wall motion score index (WMSI) to determine the recovery of hibernating myocardium and cardiac function in all patients before treatment and after 3-month follow-up. The study was to investigate the effects of safflower on hibernating myocardial revascularization and cardiac function. It was found that LVEF was significantly improved, while the ESV and WMSI were significantly reduced after 2-week treatment in safflower and PCI treatment groups. No significant differences were found between safflower and PCI treatment groups in ESV, EDV, WMSI and LVEF after treatment Safflower injection effectively improved hibernating myocardial function.

Objective To investigate efficacy and safety of YZH amblyopic therapeutic apparatus in treatment of children with amblyopia.Methods Forty patients were randomly divided into two groups.The control group received routine treatment and the intervention group was treated with YZH amblyopic therapeutic apparatus based on routine treatment.Results The effective rate was 66.67％ and ineffective rate was 33.33％ in the control group ( n =20,33 eyes).The effective rate was 97.37％ and ineffective rate was 2.63％ in the intervention group(20 cases,38 eyes).There was significant difference between the two groups( x2 =11.853 6,P ＜ 0.05).Conclusions It is effective and safe to improve children' s vision with YZH amblyopic therapeutic apparatus.During the treatment process,proper care,active cooperation and participation of parents can improve the treatment and shorten the course of disease.

Objective To explore the etiological factors,composition of the disease and nursing care for the disease of optic nerve.Methods The 375 cases patients' information were collected from October 2009 to May 2011 in the ward of neuro-ophthalmology.The retrospective study was used and the disease's characters and nursing care were summarized.Results After treatment,those patients had certain degree of curative effect and the visual acuity increased.In the etiological distribution,optic neuritis was the most factor and accounted for 37.60％ of the optic nerve disease.Health education,psychological nursing,nursing care of dysopia,and individual nursing were used for patients with optic nerve's disease.Conclusions The optic nerve diseases are very common in the ward of neuro-ophthalmology.The characteristics of the diseases include long course and complicated etiological factors.Effective nursing care and psychological intervention are very important for the patients with optic nerve disease and helpful for the recovery.

AIMTo study the four diastereomers of leucogen and structure of the related substances.

METHODSLC-DAD, LC-MS/MS and LC- 1H NMR were used. LC was carried out with a Phenomnex Luna C18 (250 mm x 4.60 mm ID, 5 microm) column and a mobile phase of water-acetonitrile-glacial acetic acid (58:42: 0.3).

RESULTSThe structures of leucogen and its related substances were identified. Leucogen and the related substances were found to have four diastereomers in solution state separately. The stability and transformation of the four diastereomers were analyzed and 3R4S5R was found to be more stable than the others according to quantum calculations.

CONCLUSIONLeucogen have four diastereomers in solution state and it can transform from one diastereomer to the others, and the 3R4S5R is more stable than the others.

OBJECTIVETo establish a method to detect N-methylacetamide (NMAC) concentration in urine of workers occupationally exposed to NMAC with directly injecting the sample into capillary gas chromatography.

METHODSAfter frozen urine samples were isolated from precipitation by centrifugation, the aliquot of supernatant was pretreated by protein precipitation with dilution of methanol. The methanol supernatant was separated by Polyethylene Glycol (PEG) capillary columns and detected by nitrogen phosphorous detector (NPD).

RESULTSGood linearity was obtained in the concentration range of 1.0 ∼ 250 mg/L. The correlation coefficient was 1.0000. The minimum detection limit of NMAC in urine was 0.2 mg/L. The method recovery rates were 96.0% ∼ 99.4% at three different concentrations. The mean recovery rate was 97.8%. The relative standard deviations (RSD) of intra- and inter-day were between 1.5% ∼ 3.4%.

CONCLUSIONThe method was simple, rapid, selective and sensitive and was applicable to detect the urinary NMAC concentration for monitoring occupational exposure levels.

OBJECTIVETo summarize the clinical presentation, pathogenesis, neuroimaging, treatment, and outcome of stroke-like migraine attacks after radiation therapy (SMART) syndrome, and to propose diagnostic criteria for this disorder.

DATA SOURCESWe searched the PubMed database for articles in English published from 1995 to 2015 using the terms of "stroke-like AND migraine AND radiation." Reference lists of the identified articles and reviews were used to retrieve additional articles.

STUDY SELECTIONData and articles related to late-onset effects of cerebral radiation were selected and reviewed.

RESULTSSMART is a rare condition that involves complex migraines with focal neurologic deficits following cranial irradiation for central nervous system malignancies. The recovery, which ranges from hours to days to weeks, can be partial or complete. We propose the following diagnostic criteria for SMART: (1) Remote history of therapeutic external beam cranial irradiation for malignancy; (2) prolonged, reversible clinical manifestations mostly years after irradiation, which may include migraine, seizures, hemiparesis, hemisensory deficits, visuospatial defect, aphasia, confusion and so on; (3) reversible, transient, unilateral cortical gadolinium enhancement correlative abnormal T2 and fluid-attenuated inversion recovery signal of the affected cerebral region; (4) eventual complete or partial recovery, the length of duration of recovery ranging from hours to days to weeks; (5) no evidence of residual or recurrent tumor; (6) not attributable to another disease. To date, no specific treatment has been identified for this syndrome.

CONCLUSIONSSMART is an extremely rare delayed complication of brain irradiation. However, improvements in cancer survival rates have resulted in a rise in its frequency. Hence, awareness and recognition of the syndrome is important to make a rapid diagnosis and avoid aggressive interventions such as brain biopsy and cerebral angiography.
