Objective To detect the levels of high mobility group box 1 protein HMGB1),tumor necrosis factor-α (TNF-α),interleukin-6 (IL-6),C-reactive protein (CRP) in order to explore the clinical significance of HMGB1 in patients with severely traumatic brain injury.Methods A total of 75 patients composed of 40 male and 35 female with severely traumatic brain injury were hospitalized from March 2011 through March 2012.The scores of Glasgow Coma Scale (GCS) were 5-8 within 12 hours after brain injury.Casualties with history of hypertension,diabetes,severe diseases of heart,liver and kidney,and with concurrent trauma of other parts of body were excluded.Another 50 healthy subjects were enrolled as controls.Serum samples were taken from both patients and controls at admission.The levels of HMGB1,TNF-α and IL-6 were measured by using enzyme-linked immunosorbent assay (ELISA).The level of CRP was measured by using automatic biochemistry analyzer.Comparisons of the levels of HMGB1,TNF-α,IL-6and CRP between casuahies and healthy controls were carried out.The correlations of HMGB1 with TNF-α,IL-6,CRP in patients with severe traumatic brain injury were analyzed.Thereafter,75 patients were divided into two groups post hoc:the death group and the survival group.On the 1st day,the 3rd day and the 7th day after trauma,serum HMGB1 was detected.The comparison of HMGB1 was made between death group and survival group by using t-test.Results Serum HMGB1 level in the traumatic patients was higher than that of healthy controls (P ＜ 0.01).Correlative analysis showed that there was a positive correlation between HMGB1 and TNF-α (r =0.365,P＜0.05),IL-6 (r=0.530,P＜0.05),CRP (r=0.661,P＜0.05) in patients with severe traumatic brain injury.Serum HMGB1 level in the death group was higher than the survival group (P ＜ 0.01).Conclusions Increased serum HMGB1 level was found after severe traumatic brain injury.There were positive correlations between HMGB1 and three inflammatory factors,TNF-α,IL-6and CRP.Serum HMGB1 should be used as reliable hiomarker to judge the prognosis of patients with severe traumatic brain injury.

Objective To investigate the causes of a suspected outbreak of lower respiratory tract infection (LR-TI)caused by carbapenem-resistant Acinetobacter baumannii (CRAB)in the general intensive care unit(ICU)of a hospital,and provide scientific evidence for effective control of healthcare-associated infection(HAI).Methods Epi-demiological investigation on patients infected with CRAB and on-site monitoring on ICU environmental hygiene from March 4 to 23,2014 were performed,active prevention and control measures were taken.Results A total of 7 patients developed CRAB infection,the total length of stay during epidemic period were 160 days,the infection density of LRTI was 43.75‰(7/160),4 of 5 patients at No.02 bed had CRAB LRTI.Univariate analysis revealed that adopting conventional sputum suction procedure was a risk factor;the qualified rate of bacterial count on the object surfaces was 31 .75% (20/63).CRAB was also isolated from outer frame of suction device of No.02 bed, which had the same antimicrobial pattern as CRAB from 7 patients’sputum.After taking a series of controlling measures,there was no CRAB infection case after March 24,2014,this outbreak was effectively controlled. Conclusion This suspected HAI outbreak may be caused by inadequate disinfection of outer frame of suction device contaminated by CRAB,and horizontally transmitted through manipulation of sputum suction by health care workers.Clean and disinfection of ICU environmental object surfaces is of great importance for preventing HAI.

Radiological evaluation is a key step for donor's preoperative evaluation in living donor liver transplantation(LDLT).There are many powerful functions in multi-slice computed tomography (MSCT)which can suit all-in-one radiological evaluation before donor's operation.By referring to the articles from home and abroad in recent years,from viewpoint of surgeon,this artical reviews the application status of multi-slice CT for preoperative assessment in LDLT,which can help to provide theory support for choice of radiological examination in LDLT donor.

Blood C-peptide,first-void fasting urinary C-peptide/creatinine ratio ( UCPCR ),second-void fasting UCPCR,and 24 h urinary C-peptide (UCP) were determined in 90 type 2 diabetics and 30 health volunteers.The results showed that first-void fasting UCPCR and second-void fasting UCPCR were positively related to 24 h UCP and the index of islet β-cell function( all P＜0.01 ).

This article reported a case of a male patient with primary hyperparathyroidism(PHPT) caused by an ectopic parathyroid adenoma in the anterior superior mediastinal. Hospital routine examinations indicated hyperlipidemia, hyperuricemia, type 2 diabetes with nephropathy, chronic kidney disease in stage Ⅳ, elevated PTH, hypercalcemia, hypophosphatemia, clinically highly suspected hyperparathyroidism. There was no obvious abnormality of parathyroid ultrasound, while 18F-FDG systemic metabolic imaging and 99mTc-MIBI dual-phase parathyroid imaging suggested that an ectopic parathyroid gland in the anterior superior mediastinal which was hyperactive. Evaluations of anterior pituitary function, pancreas, and endocrine-related hormones showed no obvious abnormalities, and thus we ruled out the possibility of multiple endocrine adenomas, combined with the patient′s symptoms and previous medical history, and ruled out the possibility of tertiary hyperparathyroidism, the patient was diagnosed as PHPT caused by the anterior superior mediastinal ectopic parathyroid adenoma. To restore the blood calcium to normal, the patient was treated with intravenous rehydration, diuresis, calcitonin to promote urinary calcium excretion, and zoledronic acid to inhibit bone resorption. Further thoracoscopic mediastinal tumor resection was performed, and the diagnosis of parathyroid adenoma was confirmed by pathology. All the indicators were normal and no recurrence of hyperparathyroidism was found during the follow-up. Integration of the patient′s clinical manifestations, biochemical indicators, and imaging examinations are necessary to diagnose PHPT qualitatively and location-specifically. In particular, it is necessary to pay attention to whether there is the possibilities of ectopic adenoma and multiple endocrine adenomas, to reduce the rates of missed diagnosis and recurrence.

Objective:To investigate the clinical and genetic features of 3-methylglutaconic aciduria, dystonia-deafness, hepatopathy, encephalopathy, Leigh-like syndrome(MEGDHEL syndrome) caused by SERAC1 gene variation. Methods:This study retrospectively described the clinical and molecular features and prognosis of a baby boy who was transferred to Children's Hospital of Fudan University and later diagnosed with MEGDHEL syndrome in August 2016. A summary of the clinical and genetic manifestations of MEGDHEL syndrome cases reported in China and foreign areas was conducted through a literature review.Results:(1) Case report: The 2-day-old patient was transferred to Children's Hospital of Fudan University due to hyperlactic acidemia after birth. Physical examination revealed scattered petechiae and ecchymoses of the skin. Laboratory examination showed coagulation disorders and cranial MRI revealed abnormal signals in both basal ganglia. A homozygous variation of c.442C>T(p.Arg148*) in the SERAC1 gene was detected in the patient, which is a pathogenic variant included in the Human Gene Mutation Database. Both of his parents were heterozygous carriers, thereby the diagnosis of MEGDHEL syndrome was confirmed. Followed up to the age of three years and 11 months, he was found to have psychomotor retardation, spasticity, dystonia, deafness, and loss of language ability. (2)Literature review: Together with the case reported in this study, a total of 88 cases were retrieved, involving 57 different variants. The clinical features were homogenous, with onset mostly in the neonatal period (72%, 62/86), and severe reversible liver dysfunction (49%, 38/77) and neonatal hypoglycemia (44%, 35/80) were the main features. Nervous system was affected since infancy and common symptoms, included hypotonia (86%, 68/79), progressive spasticity (82%, 67/82), dystonia (80%, 66/82), intellectual disability (88%, 58/66) and sensorineural hearing impairment (74%, 59/80). Furthermore, bilateral basal ganglia involvement on cranial MRI (93%,70/75) and 3-methylglutaconic aciduria (98%,80/82) were also seen. Supportive care is currently the main management, however, the prognosis is extremely poor. Conclusions:MEGDHEL syndrome should be highly suspected when reversible neonatal liver dysfunction or hypoglycemia of unknown reasons in neonatal period, followed by progressive deafness-dystonia syndrome in infancy. As the prognosis of these patients is usually poor, genetic testing may provide an early diagnosis in neonatal period.
