To establish the experts consensus on the management of delirium in critically ill patients.A special committee was set up by 15 experts from the Chinese Critical Hypothermia-Sedation Therapy Study Group.Each statement was assessed based on the GRADE (Grading of Recommendations Assessment,Development,and Evaluation) principle.Then the Delphi method was adopted by 36 experts to reassess all the statements.(1) Delirium is not only a mental change,but also a clinical syndrome with multiple pathophysiological changes.(2) Delirium is a form of disturbance of consciousness and a manifestation of abnormal brain function.(3) Pain is a common cause of delirium in critically ill patients.Analgesia can reduce the occurrence and development of delirium.(4) Anxiety or depression are important factors for delirium in critically ill patients.(5) The correlation between sedative and analgesic drugs and delirium is uncertain.(6) Pay attention to the relationship between delirium and withdrawal reactions.(7) Pay attention to the relationship between delirium and drug dependence/ withdrawal reactions.(8) Sleep disruption can induce delirium.(9) We should be vigilant against potential risk factors for persistent or recurrent delirium.(10) Critically illness related delirium can affect the diagnosis and treatment of primary diseases,and can also be alleviated with the improvement of primary diseases.(11) Acute change of consciousness and attention deficit are necessary for delirium diagnosis.(12) The combined assessment of confusion assessment method for the intensive care unit and intensive care delirium screening checklist can improve the sensitivity of delirium,especially subclinical delirium.(13) Early identification and intervention of subclinical delirium can reduce its risk of clinical delirium.(14) Daily assessment is helpful for early detection of delirium.(15) Hopoactive delirium and mixed delirium are common and should be emphasized.(16) Delirium may be accompanied by changes in electroencephalogram.Bedside electroencephalogram monitoring should be used in the ICU if conditions warrant.(17) Pay attention to differential diagnosis of delirium and dementia/depression.(18) Pay attention to the role of rapid delirium screening method in delirium management.(19) Assessment of the severity of delirium is an essential part of the diagnosis of delirium.(20) The key to the management of delirium is etiological treatment.(21) Improving environmental factors and making patient comfort can help reduce delirium.(22) Early exercise can reduce the incidence of delirium and shorten the duration of delirium.(23) Communication with patients should be emphasized and strengthened.Family members participation can help reduce the incidence of delirium and promote the recovery of delirium.(24) Pay attention to the role of sleep management in the prevention and treatment of delirium.(25) Dexmedetomidine can shorten the duration of hyperactive delirium or prevent delirium.(26) When using antipsychotics to treat delirium,we should be alert to its effect on the heart rhythm.(27) Delirium management should pay attention to brain functional exercise.(28) Compared with non-critically illness related delirium,the relief of critically illness related delirium will not accomplished at one stroke.(29) Multiple management strategies such as ABCDEF,eCASH and ESCAPE are helpful to prevent and treat delirium and improve the prognosis of critically ill patients.(30) Shortening the duration of delirium can reduce the occurrence of long-term cognitive impairment.(31) Multidisciplinary cooperation and continuous quality improvement can improve delirium management.Consensus can promote delirium management in critically ill patients,optimize analgesia and sedation therapy,and even affect prognosis.

Objective To investigate the clinical features of patients with acute ST-segment elevation myocardial infarction (STEMI) comorbid with diabetes mellitus (DM) and to analyze the prognosis within 12 months after primary percutaneous coronary intervention (pre-PCI). Methods A total of 375 STEMI patients were divided into the diabetes group (n=140) and the normal blood glucose group(n=235) according to whether they met the diagnostic criteria of DH. The clinical data,characteristics of coronary artery lesions,type of stent implant,rate of coronary slow flow or no-reflow after pre-PCI, and the prognosis within 12 months after PCI of the two groups were investigated.Results Patient in the diabetes group presented with higher mean age ,higher comorbid rates of hypertension , hyperlipidemia and heart function of Killip class Ш and above than patients in the normal blood glucose group (all P<0.05). patients in the diabetes group had higher rates of slow reflow /no-reflow after PCI(12.9% vs.5.5%,P=0.013),higher percentages of 3-ressel disease(40.7% vs. 28.9%,P=0.019)and lef t main lesions(13.6% vs. 7.2%,P=0.044). The in-hospital mortality rates(6.4% vs.1.7%,P=0.020),revascularization rates within 12 months(7.9% vs.0.9%,P=0.001)and incidence of heart failure(7.9% vs. 2.6%,P=0.017)were all higher in the diabetes group. Conclusions STEMI patients comorbid with DM were relatively older, had higher comorbidities of hypertension,hyperlipidemia, three-vessel disease, left main coronary lesions and higher mortality during hospitalization. No significant increase in cardiac death and recurrent myocardial infarction were deserved during the follow-up period. These patients may benefit more from early intervention.

Sodium taurocholate cotransporting polypeptide (NTCP) deficiency is an inborn error of bile acid metabolism caused by mutations of SLC10A1 gene. This paper reports the clinical and genetic features of a patient with this disease. A 3.3-month-old male infant was referred to the hospital with the complaint of jaundiced skin and sclera over 3 months. Physical examination revealed moderate jaundice of the skin and sclera. The liver was palpable 3.5 cm below the right subcostal margin with a medium texture. Serum biochemistry analysis revealed markedly elevated bilirubin (predominantly direct bilirubin) and total bile acids (TBA), as well as decreased 25-OH-VitD level. On pathological analysis of the biopsied liver tissue, hepatocyte ballooning and cholestatic multinucleate giant cells were noted. The lobular architecture was distorted. Infiltration of inflammatory cells, predominantly lymphocytes, was seen in the portal tracts. In response to the anti-inflammatory and liver protective drugs as well as fat-soluble vitamins over 2 months, the bilirubin and transaminases levels were improved markedly while the TBA kept elevated. Because of persisting hypercholanemia on the follow-up, SLC10A1 gene analysis was performed at his age of 17.2 months. The child proved to be a homozygote of the reportedly pathogenic variant c.800C>T (p. Ser267Phe), while the parents were both carriers. NTCP deficiency was thus diagnosed. The infant was followed up until 34.3 months old. He developed well in terms of the anthropometric indices and neurobehavioral milestones. The jaundice disappeared completely. The liver size, texture and function indices all recovered. However, the hypercholanemia persisted, and the long-term outcome needs to be observed.

The aim of this study was to investigate the clinical features and DGUOK gene mutations of an infant with mitochondrial DNA depletion syndrome (MDS). The patient (more than 7 months old) manifested as hepatosplenomegaly, abnormal liver function, nystagmus and psychomotor retardation. Genetic DNA was extracted from peripheral blood samples of the patient and her parents. Targeted Exome Sequencing was performed to explore the genetic causes. Sanger sequencing was carried out to confirm the detected mutations. The sequencing results showed that the patient was a compound heterozygote for c.679G>A and c.817delT in the DGUOK gene. The former was a reportedly pathogenic missense mutation of maternal origin, while the latter, a frameshift mutation from the father, has not been described yet. The findings in this study expand the mutation spectrum of DGUOK gene, and provide molecular evidence for the etiologic diagnosis of the patient as well as for the genetic counseling and prenatal diagnosis in the family.

OBJECTIVETo explore the role of heterogeneous nuclear ribonucleoprotein(hnRNP) K regulating autophagy in the drug resistance of acute myeloid leukemia, so as to provide a new molecular marker for treatment of leukemia.

METHODSThe relationship between the expression level of hnRNP K and the drug resistance of myeloid leukemia was verified by fluorescence quantitative PCR; the expression of autophagy related protein LC3I/ II was detected by Western blot after the hnRNP K was modulated by RNA interference technology; the sensitivity of leukemia cells to doxorubicin was analyzed before and after the expression of hnRNP K were modulatd.

RESULTSThe expression of hnRNP K and LC3I/II significantly increased in bone marrow nonremission patients and in drug resistant cell line, however, the expression of LC3I/ II decreased when the expression of hnRNP K were reduced, while the sensitivity of cells to adriamycin could be recovered.

CONCLUSIONhnRNP K may be involved in the formation of adriamycin resistance in acute myeloid leukemia by regulating autophagy.

Objective: To investigate the influence of lactulose on immunity of hepatocellular carcinoma (HCC) patients with hepatocirrhosis and hypersplenism after double-interventional therapies. Methods: A total of 40 HCC patients with hepatocirrhosis and hypersplenism, hospitalized during January 2013 to June 2014, were enrolled and randomized into control group and observation group. Both groups received partial splenic embolization combined with transcatheter arterial chemoembolization. Besides, observation group orally took lactulose 30 mL/d. Four days before interventional therapies and at days 1, 3, 7 and 14 after therapies, fasting venous blood was collected to detect white blood cell count, red blood cell count (RBC), and platelet count (PLT). Four days before therapies and at days 7 and 14 after therapies, the levels of alanine aminotransferase, aspartate transaminase, total bilirubin, malondialdehyde, super-oxide dismutase (SOD), IFN-γ, and IL-4 as well as the distribution of T cell subsets in peripheral blood were tested. Complications were observed after interventional therapies. Results: Before interventional therapies the levels of white blood cell count, PLT and RBC in both groups showed no difference, while after interventional therapies the levels of PLT and RBC in both groups showed an increasing tendency (P < 0.05). At day 14 after interventional therapies, the level of blood cell as well as that of SOD, IFN-γ and IL-4 in serum were significantly higher than that before therapies; meanwhile, the levels of alanine aminotransferase and total bilirubin of observation group after therapies were significantly lower than before and control group (P < 0.05), the levels of CD4

OBJECTIVETo investigate the protective effect of retarded removal of the unilateral necrotic testis after long-time (> 24 h) spermatic cord torsion on the contralateral testis in rats.

METHODSThirty-three male SD rats aged 21 -42 days were divided into a sham-operation group (n = 11), a torsion-reservation group (n = 12) and a torsion-orchiectomy group (n = 10). The rats of the sham-operation group received dartos pouch orchidopexy on the left testis, while those of the latter two groups underwent 720 degrees unilateral spermatic cord torsion on the left side. Ninety-six hours later, the rats of the torsion-reservation group received detorsion with the ipsilateral testis preserved, while those of the torsion-orchiectomy group underwent orchiectomy. Three months after operation, blood samples were obtained from the rats for measurement of serum testosterone and antisperm antibodies by ELISA, and meanwhile testes and epididymides were harvested for determination of the volumes of various structures and the diameter of seminiferous tubules with stereological methods.

RESULTSThere were no significant differences in the level of serum testosterone among the three groups. Anti-sperm antibody positive was found in only 1 animal in the torsion-reservation group. The Leydig cell nuclei in the contralateral testis appeared larger in the torsion groups than in the sham-operation group. Marked morphological changes were observed in 1, 3 and 0 of the animals in the sham-operation, torsion-reservation and torsion-orchiectomy group, respectively, mainly including atrophy of seminiferous tubules and reduced number of spermatogenic cells. The volume of the contralateral testis was increased by 19% and 21% in the torsion-reservation and torsion-orchiectomy group, respectively, in comparison with that in the sham-operation group (P < 0.05). No significant differences were observed in the volume of seminiferous tubules of the contralateral testis among the sham-operation, torsion-reservation and torsion-orchiectomy groups ([1.15 +/- 0.07], [1.30 +/- 0.04] and [1.35 +/- 0.05] cm3). The volume of the interstitial tissue was significantly increased in the latter two groups ([0.36 +/- 0.02 and 0.34 +/- 0.03] cm3) as compared with the former ([0.25 +/- 0.02] cm3) (P < 0.05). The diameters of the seminiferous tubules exhibited no significant differences among the three groups ([226.00 +/- 7.00], [223.00 +/- 6.00] and [221.00 +/- 3.0] microm).

CONCLUSIONLong-time unilateral spermatic cord torsion may result in compensatory hypertrophy of the contralateral testis, and orchiectomy does not significantly affect the histology of the contralateral testis and epididymis.

This study was aimed to investigate the effect of homoharringtonine (HHT) on K562 cell proliferation, apoptosis and expression of BCL-2 and NF-κB proteins. The cells proliferation was assayed with MTT method, the cell apoptosis, cell cycle and BCL-2 expression were analyzed with flow cytometry, NF-κB protein expression was detected with Western blot. The results showed that HHT concentration-dependently inhibited proliferation of K562 cells, the IC50 at 48 h was 43.89 ng/ml. Treated with HHT 10 ng/ml for 48 h, K562 cell apoptosis significantly increased, cell cycle was blocked at G0/G1, the expression level of BCL-2 and NF-κB proteins was lower than that in control group (P < 0.05). It is concluded that HHT may inhibit the proliferation of K562 cells, and down-regulating expression levels of BCL-2 and NF-κB may be one of its anti-CML mechanisms.
