Objective To investigate the effect of nutritional guidance on the energy intake and body weight of patients with gastric cancer chemotherapy. Methods The experimental study was used to study the 144 cases with gastric cancer for the first time of chemotherapy. They were randomly divided into the experimental group and the control group, 72 cases in each group. Routine healthy guidance was used in the control group, while the patients in the experimental group were treated by the nutrition prescription, the nutrition guidance, the purpose and the significance of the chemotherapy, and the follow-up of the patients after discharge. The body weight of patients was collected before chemotherapy, and the dietary questionnaire was used for second days after first days of dietary intake, and the changes of energy consumption and body weight were compared between the two groups. Results The mean values of energy intake within 24 hours in the first 3 days after the chemotherapy in the experimental group was 5 068.92 kJ, which was 51%of the RNI. The mean values of energy intake within 24 hours in the first 3 days after the chemotherapy in the control group was 3 439.25 kJ, which was 38%of the RNI. The difference between the two groups was significant (P<0.01). The weight of patients in the experimental group at the time point of before the 5th and 6th time of chemotherapy were significant higher than those in the control group (P<0.05). Energy intake had influenced the patients′weight, high energy intake with low decrease of body weight. Conclusions Nutritional guidance can effectively improve the energy intake of patients with gastric cancer when chemotherapy, so that the weight remained stable during chemotherapy.

Objective To explore the clinical features,genetic causes and prognosis of intellectual disability with epilepsy(ID-E)in children.Methods The data of unknown causes of ID-E children(n=40)who were identified in Department of Pediatrics,Xiangya Hospital of Central South University from March 2015 to March 2016 were respectively analyzed,and follow-up studies were performed to investigate the epilepsy control and intellectual deve-lopment.Results Forty unexplained ID-E included 25(62.5％)male,and 34(85.0％)cases were severe intellectual disability patients.The onset age of epilepsy was 0.16 to 8.00 years old,median age was 1.5 years old.Twenty cases(50.0％)had slow electroencephalogram background,and 22 cases(55.0％)had focal spikes.Ten cases(25.0％)had abnormal cranial images,with brain dysplasia or atrophy.Follow-up lasted from 0.58 to 1.58 years,and 19 cases(47.5％)had seizure control.Twenty-five cases(62.5％)had used at least 2 anti-epilepsy drugs during follow-up,and 19 cases(47.5％)had drug refractory epilepsy.Improvement of mental or motor development in epilepsy controlled group and the uncontrolled group were 12 cases(63.2％)and 2 cases(9.5％).There were separately 8 cases(8/40 cases,20.0％)and 3 cases(3/16 cases,18.8％)diagnosed respectively by whole genome-wide analysis of copy number variants(CNVs)and gene-panel whose CNVs test findings were negative.Conclusions ID-E patients of unknown causes have the following clinical features:they were mostly found in male patients with severe intellectual disability,and drug refractory epilepsy patients have rather high percentage;well controlling of epilepsy is useful for improvement of mental and motor development.Genetic analysis is significant for control and prognosis of ID-E patients,and genome-wide CNVs have high positive rates which can be used as first-tier test to detect genetic etiology of ID-E of unknown cause.

Objective To analyze the clinical characteristics and treatment of children with tuberous sclerosis (TSC) complicated with epilepsy,so as to improve the level of diagnosis and treatment and improve the prognosis of children with TSC.Methods The clinical data of TSC children complicated with epilepsy diagnosed and followed up in Xiangya Hospital of Central South University were collected and analyzed retrospectively.Results Of the 51 children,49 (96.1％) had their first visit because of epileptic seizures.Their electroencephalogram (EEG) showed epileptiform discharges during the epileptic period.The therapeutic effect of vigabatrin on TSC patients with spastic seizures was significantly different from that of antiepileptic drugs alone or in combination.Conclusions Epileptic seizure is the most common reason for first visit and seizure control will affect the prognosis of children to a large extent.Vigabatrin had remarkable effect on TSC patients with spasm seizure,and rapamycin has broad prospects in the treatment of children with TSC.

This patient presented with fever,seizure and bulging fontanelle when he was 6-month-old.According to the investigations,white blood cell (WBC),erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) increased significantly,and Streptococcus Pneumonia grew in both blood and cerebrospinal fluid (CSF).He responded to standard antibiotic treatment poorly even it lasted long enough.At the same time,the inflammation seemed to be over-activated,the WBC level was still elevated,high fever continued.Thus they thought of primary immunodeficiency and sent blood sample for gene panel testing (Sanger sequencing) but got negative result.At last,they added steroid together with anti-tuberculosis drug therapy,his temperature as well as the intracranial pressure became better ever since.At the age of 1 year and 1 month,he got another Streptococcus Pneumonia meningitis,while he was still on anti-tuberculosis drug therapy and tapering off steroid.At this time,he presented with coarse hair,hypohidrosis and delayed eruption of teeth,which strongly indicated Anhidrotic Ectodermal Dysplasia with Immunodeficiency (EDA-ID).NEMO is the most common gene responsible for EDA-ID and locates on X chromosome.It has a pseudogene named IKBKGP which locates downstream of NEMO.IKBKGP and NEMO share 3-10 exons with the homology of 99.8％,which makes it difficult to find out most real mutations within NEMO with Sanger sequencing.Then they performed PCR with the primer starting upstream of the shared exons.Finally,they found out the pathogenic mutation [c.505G ＞ C(p.A169P)] of NEMO,which has been reported.This finding led us to make the right diagnosis as well as the proper treatment and the prognosis for this patient.

Objective To explore the effects of improved intubation in preventing accidental PICC intubation into internal jugular vein. Methods 180 patients with PICC were randomly divided into two groups:control and trial group.In the control group, the routine intubation with head sided was performed,and in the trial group,the intubation was done with gauze of different size accord-ing to the space between the neck and shoulder pressed downward and inward at the spot of internal jugular vein to the bottom and meanwhile having the patient turn the head aside and press the gauze with their draw when the tube head was inserted 15 cm deep.The two groups were compared in terms of the rate of PICC intubation into internal jugular vein.Result The incidence of catheterization by accident into the internal jugular veinin the trial group was significantly lower than that of the control group (P＜0.05). Conclusion The intubation with gauze pressed at the internal jugular vein can obviously reduce the incidence of catheterization by accident into the internal jugular vein.This method is worthy of clinical popularization and application.

Objective: To investigate the clinical features, diagnosis and treatment of febrile infection-related epilepsy syndrome (FIRES). Methods: The clinical data of 12 children with FIRES admitted to Xiangya Hospital of Central South University from 2015 to 2018 were retrospectively analyzed. The basic information, clinical manifestations, electroencephalogram, imaging examination, treatment and prognosis were analyzed. Results: Of the 12 patients, 7 were male and 5 were female. The age of onset was (7.0±3.7)years (1.3 year to 13 years). The average hospitalization time (34-86 days, median 52 days). Twelve patients were healthy before the disease, and had fever before convulsion. The interval between fever and seizure was (3.5±1.7)days (1-7 days). The status epilepticus and consciousness deficit were the main clinical manifestations. The electrogram of 8 patients showed status epilepticus when admitted. 12 patients had disturbance of consciousness; the acute episodes were focal seizures (100%, 12/12) and generalized tonic-clonic seizures (41.7%, 5/12). All patients used 3-5 antiepileptic drugs (median 4), all treated with hormones and gamma globulin. 4 patients with ketogenic diet (KD) were treated within 2 weeks of onset, and the average duration from onset to electroencephalogram (EEG) improvement was (19.2±5.0)days. In 8 patients who did not use KD within 2 weeks of onset, the average duration from onset to EEG improvement was (29.9±9.6)days. Conclusions FIRES is more common in normal children with school age. The main manifestation is refractory status epilepticus in the days after acute fever, focal episodes of seizures, anti-epileptic drug resistance. Early initiation of KD produces a favorable prognosis.

Autoimmune encephalitis(AE) is one of the most rapidly developing research fields in pediatric neurology.Previous studies have indicated that delayed-use or non-use of immunotherapy will lead to poor prognosis.Therefore, this article summarizes the current opinion of immunotherapy and prognostic factors for AE in order to provide treatment guidance for clinicians.

Objective To investigate the effect of schisandrin (SCH) treatment on learning and memory abilities and their mechanism in APP/PS1 dual transgenic dementia mice,and explore the effect of Chinese medicine on Alzheimer's disease (AD).Methods Thirty-five APP/PS1 dementia mouse models were randomly assigned into APP/PS1 model group (n=17) and APP/PS1+SCH group (n=18);another 10 male C57BL/6J mice were chosen as blank control group.The mice in the APP/PS1+SCH group were given intragastric administration of SCH at 2.6 mg/(kg· d) for 30 d;the mice in the APP/PS1 model group and blank control group were treated with distilled water for 30 d.The learning and memory abilities of these APP/PS1 mice (n=7) were detected by Morris water maze.Mice from the three groups were sacrificed;Nissl staining was used to observe Nissl bodies of neurons in brain tissues;real-time fluorescence quantitative PCR (qPCR) was used to detect the mRNA content of terminal glycosylationend products receptor (RAGE) in brain tissues;Western blotting was used to detect the expressions of RAGE and phosphorylated P38 mitogen-activated protein kinase (p-p38) in brain tissues.Results (1) The results of water maze space exploration experiment showed that the times of crossing the platform area in the three groups were statistically significant (P＜0.05);as compared with the APP/PS1 modelgroup,the times of crossing the platform area in the APP/PS1+SCH group were significantly increased (P＜0.05).(2) Nissl staining results showed that the contents of Nissl bodies in the hippocampal CA1 area and cortical neurons of the APP/PS 1 model group were significantly reduced,with light staining and cell body atrophy;the lesions in mice of the APP/PS1+SCH group were less severe than those of APP/PS1 model group,some neurons were atrophic,and the content of the neuronal nileite bodies in the hippocampal CA1 region was relatively abundant.(3) The qPCR results showed that there were statistically significant differences in RAGE mRNA expression levels in the cortex and hippocampus of the three groups (P＜0.05);as compared with the APP/PS1 model group,the APP/PS1+SCH group had significantly reduced RAGE mRNA expression in the hippocampal area (P＜0.05).(4) Western blotting results showed that RAGE and p-p38 protein expression levels in two parts of mice of APP/PS1+SCH group were significantly reduced as compared with those in the APP/PS1 model group (P＜0.05).Conclusion SCH may improve the functional status of hippocampal and cortical neurons and improve the spatial exploratory memory ability of APP/PS1 mice by down regulating the RAGE and P38 expressions.

Abnormal fatty acid metabolism is one of the unique metabolic ways in which malignant cells maintain their growth needs and plays a crucial role in tumor progression.Acetyl-CoA carboxylase (ACC) is the rate-limiting enzyme in fatty acid synthesis and oxidative metabolism.More and more researches confirm that ACC is highly expressed in many tumors,and is closely related to tumor progression and prognosis of patients,which makes ACC as a potential marker for clinical diagnosis and prognosis.Tumor cell fatty acid synthesis can be blocked and fatty acid β oxidation can be stimulated by inhibiting the activity of ACC,resulting in serious lipid consumption of tumor,and then inhibit tumor growth and proliferation.Investigating the effect and molecular mechanisms of ACC in the genesis and development of tumors can provide a new insight into cancer targeted molecular therapy.
