Objective To explore the features of clinical manifestations and electrophysiology of spinal muscular atrophy(SMA) in children.Methods The clinical features and laboratory data were analyzed in 32 children with SMA,electromyography tests were carried out in 28 patients and the muscle biopsy were performed in 24 cases.Results The 32 cases were subdivided into 3 clinical groups,15 cases were SMAⅠ,12 cases were SMAⅡ,5 cases were SMAⅢ.They were all characterized by progressive muscle weakness associated with hyptonia and atrophy.The clinical distinction between SMAⅠto SMAⅢ reflected different age of onset and disease severity.All cases of SMAⅠhad symptoms of respiratory disability,only 1 case of SMAⅡ had paradoxical breathing and none of SMAⅢ had similarly symptoms.Electromyographic studies showed a pattern of denervation with no sensory involvement.The rate of spontaneous potential was 87%,with gentle strain,the duration of motor unit was extended(30%-150%) and the amplitude of it was increased(90%-450%),the motor nerve conduction velocity was reduced slightly in 28% patients.The muscle biopsy provided evidence of skeletal muscle denervation with groups of atrophy.Conclusions The clinical features,the changes of electromyography and the muscle biopsy are valuable for diagnosis of SMA.Respiratory management will prolong survival and improve the quality of life for these patients.

ObjectiveTo investigate the effect of nickel-titanium(Ni-Ti) shape memory alloy embracing internal fixer on oblique or spiral fracture.Methods23 cases with spiral or oblique fracture accepted internal fixation with Ni-Ti shape memory alloy embracing.The time of bone healing,articular function,the appearance and function of the wound extremity were evaluated after 9～34 months follow-up.ResultsAll fractures healed in 4～16 weeks after operation.None infection,nonunion,embracing emersion or break had been found. The fine rate was 91.3%.ConclusionThe effect of Ni-Ti shape memory alloy embracing internal fixer on long spiral or long oblique fracture is satisfactory.

The levels of triglyceride(TG)and free fatty acid(FFA)in serum,liver,skeletal muscle,and pancreas of lipoprotein lipase gene knockout heterozygous(LPL+/-)mice and C57 mice were determined.Intraperitoneal glucose tolerance test(IPGTT)was performed to evaluate insulin sensitivity and β-cell function.The results showed that the Iipid content in 16 weeks LPL+/- group did not increase significantly.The TG and FFA contents in 28 weeks LPL+/- group were significantly higher than those in control and 16 weeks LPL+/-group(all P<0.05).In 50 weeks LPL+/- group,FFA levels in serum and pancreas,and TG content in pancreas increased significantly compared with other three groups(all P<0.05).The IPGTT result showed that the blood glucose levels increased from 15 to 120 min,not at 0 and 5 min.The blood glucose levels during 30-120 min increased significantly in 50 weeks LPL+/- group compared with other three groups(P<0.05).Fasting insulin(FINS),homoestasis assessment of insulin resistance(HOMA-IR)and pancreatic β cell function also increased gradually with age.FINS and HOMA-IR in 28 weeks LPL+/- group were higher than those in control and 16 weeks LPL+/- group.These results suggest that LPL is a key enzyme in lipid metabolism and plays a crucial role in the development of insulin resistance and diabetes.

A novel biosensor for aflatoxin B1 detecting has been reported. The biosensor electrode for AFB1 detecting was assembled by immobilized aflatoxin-oxidoreductase using open-ended multi-walled carbon nanotubes as matrix. Its linear range was between 0.16?M and 3.2?M. And if the specific anti-aflatoxin B1 antibody and aflatoxin oxidoreductase were both immobilized on the electrode with Multi-Walled carbon nanotubes, the detection limit of the modified electrode could be 16 nM with a 10 times improved sensitivity. The aflatoxin enzyme biosensor assembled this way strode one step forward its practical application.

ObjectiveTo investigate the current situation of intensive care unit (ICU) inpatients in Infectious Disease Hospital of Nanning to provide a reference for the prevention and control of infectious diseases and construction and development of ICU in such a hospital.Methods The clinical data of inpatients from January 2011 to December 2015 in the Infectious Disease Hospital Affiliated to Guangxi Medical University (that is the Fourth People's Hospital of Nanning City) were retrospectively analyzed, and the distributions of patients with various diseases, ages, of the characteristics of children severe infectious diseases in ICU, the numbers of patients with infectious diseases in general ward and ICU, the average time and daily cost of hospitalization and mortality were conducted.Results During 2011 to 2015, 855 cases in ICU were treated, including 709 cases of infectious diseases, 146 cases of non-infectious disease. The top 5 infectious diseases were ranked as follows: tuberculosis, human acquired immune deficiency syndrome (AIDS), hand-foot-mouth disease (HFMD), viral hepatitis, tetanus, accounting for 96.47% of the total infectious disease inpatients in ICU; there were 25 cases of other legal infectious diseases, accounting for 3.53%, including dengue fever, measles, malaria, chicken pox, mumps, rabies, typhoid fever, paratyphoid fever, scrub typhus, bacillary dysentery, leptospirosis, human infections with highly pathogenic H7N9 avian influenza, epidemic hemorrhagic fever, A H1N1 influenza, and besides, critically ill patients carrying virus (viral hepatitis B and AIDS) in 7 pregnant women, 22 surgical patients, and 117 patients with internal medicine diseases were also admitted and treated. The top 4 infectious diseases causing deaths in ICU were tuberculosis, AIDS, viral hepatitis and HFMD: The infectious diseases with top 6 high mortalities in ICU were as follows: rabies, viral hepatitis, AIDS, tuberculosis and tetanus. The age range was wide in this study, from 73 days to 97 years, among which there were 167 cases of pediatric infectious diseases from pediatric department, accounting for 23.55% of ICU inpatients, being mainly severe HFMD, tuberculosis and severe varicella. From 2011 to 2015, the number of hospitalized patients showed a rising trend, and the average length of stay of patients in general wards presented a downward tendency, but the average time of hospitalization of inpatients with infectious disease in ICU, mortality and daily cost of hospitalization revealed a gradually increasing trend year by year.Conclusions It is of far-reaching significance to master the spectrum of dangerous severe infectious diseases to deal with the infectious disease epidemic situation and outburst with public health events.

Objective To summarize the clinical characteristics and causes of ischemic cerebrovascular disease(ICD)in children.Methods A retrospective analysis was conducted on the clinical data of 53 cases with ICD from Feb.2002 to Jun.2008 at the department of neurology in Wuhan Children's Hospital.The self-designed questionnaire of children with ICD was used,whose items included patients' age,gender,personal history,clinical features,cerebrospinal fluid examination,neurological imaging,immunologic examination,metabolic examination,and so on.Results Of 53 children with ICD,30 cases(56.6%)were male,and 23 cases(43.4%)were female.Patients' age varied from 9 months to 12 years old,in which 45 cases(84.9%)were less than 6 years old.Patients from rural area(60.4%)were more than those from city(39.6%).Ratio of limb paralysis was 75.5%(40 cases)in first clinical symptomatology of children with ICD,including hemiplegia in 32 cases(60.4%),alternate hemiplegia in 5 cases(9.4%)and monoplegia in 3 cases(5.7%).Skull CT/MRI scan was performed to reveal 27 cases(50.9%)with basal ganglia region infarction and secondly 15 cases(28.3%)with multi-lobar infarction.Forty cases were found in abnormal cerebrovascular image by means of magnetic resonance angiography/digital subtraction angiography,in which middle cerebral artery and its branches were involved in 21 cases(52.5%).There were 41 cases(77.4%)of patients to be found with clear causes,of which 13 cases(24.5%)were of infections,8 cases(15.1%)of moyamoya disease,5 cases(9.4%)of cerebral vascular malformations,4 cases(7.5%)of head trauma.However,another 12 cases(22.6%)of patients had unknown etiology.Conclusions Children with ICD had characteristics themselves.The limb paralysis was mostly the first symptoms,and the middle cerebral artery and its branches lesions were the most common locations in children with ICD,and next the internal carotid artery involvement,anterior cerebral artery involvement,posterior cerebral artery involvement,cerebral vascular malformations,and so on.Their major cause was infection,followed by Moyamoya disease,cerebrovascular malformations and head trauma,and there were still some unknown causes.
