ABSTRACT
Objective:To investigate the biofilm-forming abilities of pathogens associated with contact lens related microbial keratitis and to compare the efficacies of different treatments in eliminating biofilms in contact lens cases (CLCs).Methods:Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli and Candida albicans biolm formation in polypropylene CLCs was examined by using a static biofilm formation model, which was incubated at 37 ℃ for 24 hours.According to the CLC treatment methods, the experimental groups were divided into a control group, a room temperature air-drying group, a contact lens care solution soaking group, a heat-drying group and a soaking-heating group.A pathogen colony counting-based serial dilution micro-counting method was applied to evaluate the biofilm elimination efficacies and pathogen killing rates of treatments.Results:All four tested strains formed biofilms on the inner walls of the CLC, and the biomasses of S. aureus, P. aeruginosa, E.coli and C. albicans biofilm were (10.78±2.12), (9.19±0.57), (8.03±0.30), and (7.50±0.07)lg CFU/ml, respectively.The S. aureus biofilm biomass was significantly higher than those of the other strains (P<0.05). The biofilm biomasses of all the tested strains in the heat-drying and the soaking-heating groups were significantly lower than those in the control group (all at P<0.05); and the biofilm biomasses of S. aureus and E. coli in the soaking group were significantly lower than that in the control group (all at P<0.05). The heat-drying treatment resulted in a killing rate of (51.76±16.75)% for S. aureus, (68.63±4.43)% for P. aeruginosa, (83.51±13.97)% for E. coli, and (97.13±5.19)% for C. albicans, respectively (F=31.806, P<0.001). Significant differences were observed between the killing rates for each bacterium (all at P<0.05). The E. coli and C. albicans killing rates of the soak-heating treatment were (100.00±0.00) % and (97.79±7.67)%, respectively, and were significantly higher than (81.13±14.86)% of S. aureus and (74.22±11.91)% of P. aeruginosa (all at P<0.05).Conclusions:Heating alone or combined with the use of contact lens care solution treatment can improve the pathogen killing rates and effectively eliminate the bacterial and fungal contaminations in CLCs.

ABSTRACT
ObjectiveTo study the effect of low molecular weight heparin sodium (LMWHS) therapy for exertional heat stroke (EHS) patients with pre-disseminated intravascular coagulation (pre-DIC).Methods A prospective randomized controlled trial (RCT) was conducted. Thirty-six patients with EHS with pre-DIC admitted to Department of Critical Care Medicine of 180th Hospital of Chinese PLA from April 2012 to November 2014 were divided into heparin sodium group (n = 20) and LMWHS group (n = 16) in accordance with the random number table. All patients received bundle treatment after being admitted to the hospital, including rapid cooling, fluid resuscitation, organ support (mechanical ventilation, hemopurification if necessary), supplement of pro-coagulation factors, etc. The patients in heparin sodium group were treated with continuous heparin sodium 12 500 U throughout 24 hours with intravenous pump for 5 days, and the patients in LMWHS group were given LMWHS 2 500 U subcutaneously, twice a day for 5 days.The incidence of DIC, incidence of bleeding and mortality of two groups were compared.The platelet count (PLT), prothrombin time (PT), activated partial thromboplastin time (APTT), fibrinogen (Fib) and D-dimer of each patient between pre and post treatment times were compared.Results No significant difference was found in the incidence of DIC and mortality between LMWHS group and heparin sodium group (31.2% vs. 30.0%,χ2 =0.007,P = 0.936; 6.2% vs. 5.0%,χ2 = 0.026,P = 0.871). Incidence of bleeding during treatment in LMWHS group was significantly lower than that in heparin sodium group (12.5% vs. 45.0%,χ2 = 4.425,P = 0.035). After treatment,PLT in both LMWHS group and heparin sodium group was significantly increased compared with that before treatment (×109/L: 140.5±17.5 vs. 110.5±16.5, 152.6±21.5 vs. 120.0±20.0, bothP 0.05). No significant difference was found in PT and Fib between pre and post treatment in all the patients.Conclusion When LMWHS was applied in EHS patients in pre-DIC stage, it could not only prevent DIC as efficiently as heparin sodium, but also results in lower incidence of bleeding. So LMWHS is safer.
ABSTRACT
@# Objective To investigate the intelligence level and structure of children with spastic diplegic cerebral palsy. Methods 67 children with spastic diplegic cerebral palsy were evaluated with Wechsler Preschool and Primary Scale of Intelligence and Wechsler Intelligence Scale for Children-Chinese Revised. Results The total intelligence quotients were (71.10±15.95) in the younger children (aged below 6 years and 5 months) and (73.12±16.02) in the older children (aged above 6 years and 5 months). The ratio of mental deficiency (44.78%) was less than that of children with cerebral palsy. For the older children, their verbal intelligence quotient was higher than performance intelligence quotient (P<0.01), and their scores of space and concentration factors were lower than that of conception and acquisition factors (P<0.05). Conclusion The intelligence development delayed in the children with spastic diplegic cerebral palsy, but better than that of children with cerebral palsy, with special structure.

ABSTRACT
Objective To investigate neuroimaging and its correlation with clinical aspects of cerebral palsy (CP).Methods A retrospective study of 295 children with CP was conducted.Magnetic resonance imaging (MRI),the gross motor function classification system (GMFCS) and intelligence testing were administered,and any correlations among these measures was analysed.Results Among the 295 cases,257 presented abnormal MRIs (87.1％) due to brain maldevelopment (n =11),periventricular leukomalacia (PVL) (n =173),cortical/subcortical lesions (n =17),basal ganglia lesions (n =26),cerebellar maldevelopment (n =11) or others lesions (n =19).Thirty-nine presented with normal MRIs.About 26％ were rated at GMFCS level 1,18％ at level 2,17％ at level 3,19％ at level 4 and 20％ at level 5.Almost 82％ of the children presented with brain maldevelopment and 84.4％ with PVL-induced spastic bilateral paralysis.In 41％ of the children with cortical or subcortical lesions,induced spastic hemiplegia was observed,whereas 47％ had induced spastic bilateral paralysis.In 77％ of the children with basal ganglia lesions induced involuntary movement was observed,and all of those with maldevelopment of the cerebellum were ataxic.Most of those with spastic hemiplegic,bilateral paralysis,involuntary movement and ataxia were on GMFCS levels 1 or 2,with only 3.7％,33.5％,64.1％ and 46.2％ respectively on GMFCS level 4 or 5.Among those in whom the MRI revealed brain maldevelopment,9.1％ were on GMFCS level 1 or 2.The corresponding percentage for PVL was 43.9％,for cortical or subcortical lesions 58.8％,for basal ganglia lesions 19.2％ and for cerebellar maldevelopment 27.3％.The balance in each category were on GMFCS level 4 or 5.Epilepsy was most common in the children with brain maldevelopment (36.4％) or cortical or subcortical lesions (41.2％).Mental retardation was most common in cases of brain maldevelopment (45.5％),cortical or subcortical lesions (41.2％) or cerebellum maldevelopment (36.4％).The incidence of epilepsy and mental retardation was higher among the children on levels 4 and 5 than on levels 1 and 2.Conclusions Neuroimaging correlates significantly with the type of CP and GMFCS level.Epilepsy and mental retardation are most common in children with brain maldevelopment or lesions.The incidence of epilepsy and mental retardation is higher among children rated at GMFCS level 4 or 5 than among those on levels 1and 2.
ABSTRACT
@#Proposed definition of cerebral palsy(CP) is a group of disorders of the development of movement and posture, that are attributed to non-progressive disturbances that occurred in the developing fetal and infant brain. Types of cerebral palsy are divided into spastic(diplegia, hemiplegia, quatriplegia), dyskinetic(athetotic, dystonic), ataxic (simple ataxia, ataxic diplegia), and mixed CP(primarily spasticity with athetosis).
ABSTRACT
@# The causes of cerebral palsy are multifactorial, including antenatal, intrapartum and postnatal. Domestic scholars generally believed that intrapartum and postnatal factors are the main reasons for cerebral palsy, while in recent years, the foreign scholars suggest that prenatal factors account for the majority of the causes of cerebral palsy. This paper is to review the recent research on the causes of cerebral palsy and to introduce the theory of etiological pathway and determine the period of brain injury in cerebral palsy patients.
ABSTRACT
@#Objective To investigate the clinical and intellectual characteristics of children with cerebral palsy of ataxia type.Methods Twenty-one children with cerebral palsy of ataxia type were evaluated by the illness history,clinical physical examination,brain MRI scan and intellectual assessment.Results Delayed motor milestones and dysfunction of balance were found in these children,and 80.9% of brain MRI scan was abnormal as cerebellar damage,and delayed intellectual ability found in these children was ameliorated as improvement of motor function.Conclusion Cerebral palsy of ataxia type is mainly caused by cerebellar damage manifests as delayed motor function,dysfunction of balance and mental retardation.
ABSTRACT
@#Objective To investigate the relationship between magnetic resonance imaging(MRI) and the type of cerebral palsy (CP) and gestational age at birth.MethodsThe MRI and clinical data of 224 CP children with spastic type were analyzed retrospectively.ResultsAmong these children, 27 cases had spastic hemiplegia, 149 had spastic diplegia, and 48 had spastic tetraplegia. 201 cases (89.7%) had abnormal MRI result. The abnormal rate of MRI in spastic hemiplegia, diplegia and tetraplegia were 100%, 87.2% and 91.7%, respectively. Periventricular leukomalacia (PVL) was observed mostly in children with spastic diplegia, other types of brain lesions were uncommon. In spastic tetraplegia the lesions were more varied. Three predominated types of MRI abnormalities were: PVL (45.8%), term-type brain injuries (20.8%) and congenital brain abnormalies (18.8%). Unilateral lesions were observed mostly in children with hemiplegia spastic diplegia born at term who showed unilateral motor disorder and upper extremity were heavier than lower extremity. Unilateral and bilateral PVL were observed in children with hemiplegia spastic diplegia born at preterm who showed lower extremity were heavier than upper extremity. Of 152 cases with PVL, 108 cases (71.1%) were preterm infants and 44 cases (28.9%) were term infants. Of 22 cases with term-type brain injuries, 20 cases (90.9%) were term infants. PVL was most observed in preterm brain injuries and was observed most in preterm children but was also in term children. Term-type brain injuries (border-zone infarct, basal ganglia-thalamic lesion, subcortical leukomalacia, and multicystic encephalomalacia) were observed most in term and rare in preterm children.ConclusionThe MRI findings in CP show a good correlation with type of CP and gestational age.
ABSTRACT
Objective To discover the distribution of ammonia nitrogen in groundwater of Shunyi District and its influencing factors. Methods 286 monitored points in low-flow period and 100 in high-flow period were chosen in 19 towns in Shunyi District. Concentrations of ammonia nitrogen, iron and manganese, and the total bacterial count of water samples were determined and evaluated based on the Guidelines for Drinking Water Quality and related standard during Jan.-Mar., Aug.-Sep., in 2005. Results All the monitored points were deep groundwater. The median of ammonia nitrogen concentration in groundwater was 0.010 mg/L in low-flow period, and 0.140 mg/L in high-flow period. The relativity was not found between the concentration of ammonia nitrogen,total bacterial count in water sample and pollution source around the well. However the concentration of ammonia nitrogen was positively correlated with the concentration of nitrite nitrogen(r=0.224, P
ABSTRACT
@#ObjectiveTo explore clinical features of cerebral palsy of premature infants and attempt to deduce the etiology and time of brain damages.MethodsMaterials included perinatal risk factors, neurodevelopmental evaluation, types of cerebral palsy and CT or MRI findings of 281 cerebral palsied children embryo age less than 37 weeks were analyzed retrospectively.ResultsAmong 281 cases, 47.07% of them were premature infants and most of them (64.67%) suffered from multiple high risk factors especially during perinatal and post neonatal periods. The main causes were perinatal asphyxia, icterus, and twin pregnancy. Spastic diplegia was more common in this group (70.81%), followed by athetosis and mixed of spastic and athetosis. The characteristic of neuroimaging findings was periventricular leukomalacia (PVL).ConclusionFor cerebral palsy of premature children, pematurity is an important cause of cerebral palsy and brain damages are often occurred during perinatal and post neonatal periods, main type is spastic diplegia, and main pathological change is PVL.
ABSTRACT
Microfilariae (mff) obtained from the peritoneal cavities of infected jirds (Meriones unguiculatus) were injected intravenously into 6 mouse strains: SMMC/B, BALB/cCR, LACA, ICR/JCL, 615 and Kunming strain. The mff in the peripheral blood of the 6 mouse strains in the above sequence were detectable within 1-150, 24-80, 30-60, 3-96, 12-45 and 45-60 days after inoculation of 2 ? 105 mff per mouse. The survival period of mff was longer in SMMC/B mice than in mice of the other strains, and the density of mff in blood was also higher in the former than in the latter. Out of 18 SMMC/B mice 13 remained microfilaria-positive on the 60th day after inoculation. The duration and level of microfilaraemia were proportional to the dose of parasites injected Microfilariae disappeared from the peripheral blood of all mice 3 days after injection of 1 ?104 mff, but were still detectable 60 days after injection of 2 ? 105 mff. In addition, mff disappeared much faster from the peripheral blood of SMMC/B mice after the second inoculation than after the first one. Although the mff had already disappeared from the peripheral blood of the infected and reinfected mice for about 1 to 2 months, they could still be found in the internal organs, mostly in the small blood vessels of the lungs (about 90%). The mff maintained a nocturnal sub-periodicity in the recipient mice, similar to those observed in the donor jirds, with a peak density hour between 2:28 and 5: 48 a.m.The results show that this mouse model might be a simple and useful system in which various factors controlling the fate of mff can be studied independently.
ABSTRACT
Male mice weighting 25-32g were infected with larvae of Trichinella spiralis. Skin administrations of mebendazole composite cream were carried out on the mice in 3 different experiment groups. It was found that there were the reduction rate of worms at 97.3%, 100% and 99. 7% in the adult worm group (50 mg/kg x 1 d), in the invasive larvae group (25 mg/kg x 7 d) and in the encysted larvae group (25 mg/kg x 7 d), respectively. These results indicate that mebendazole composite cream is very effective against both intestinal and muscular phases of T. spiralis.
ABSTRACT
This paper deals with the susceptibility of 8 inbred and 1 outbred mouse strains infected with L. donovani. Each mice was inoculated intraperitoneally with 3?106, 9?106, 2?107 amastigotes and was killed on 29-30 th, 48-49 th, 58-59 th day after infection for examination respectively .Except one of C57BL strain received 3 ? 106 amastigotes,the results showed that all mice of 615 ,C57BL ,SMMC/C?615 strains became positive at autopsy with a highly intensive infection .The greater the amastigotes was inoculated,the havier the infection would be.The 3 strains, therefore, were susceptibility to acute infection of L.donovani.The other mouse strains failed to be infected(SMMC/B, SMMC/C, ICR/JCI and Kunming strains)or only showed mild infectons(SMMC/A and SMMC/D), indicating that these 6 mouse strains were relatively resistant to infection with the parasites. In the light of the origin of these mouse strains it seems that the genetic control is highly concerned in the host susceptibility to L. donovani.
