With the rapid development of critical care medicine (CCM) in China, there are increases in the number of intensive care units (ICUs), the scale of one center ICU and the team. Subspecialty construction of CCM is of great concerns for personnel training as well as discipline development, and is currently one of the urgent problems that need to be resolved. Experience of CCM subspecialty construction from Europe and the United States is lacking and it is necessary to propose some opinions on innovation to construct CCM subspecialties with Chinese characteristics. We believe that CCM sub-specialties construction should be based on the core knowledge (pathophysiology) and skill (organ monitoring and support). The following 7 sub-specialties can be set up: ① acute lung injury and mechanical ventilation; ② shock, hemodynamic monitoring and treatment; ③ acute kidney injury and blood purification; ④ sepsis and anti-infective therapy; ⑤ stress, sedation and analgesia; ⑥ nutrition and metabolic support; ⑦ coagulation, immune and inflammation. The core knowledge and skills of critical care medicine will constantly be updated and enriched. Therefore, sub-specialty settings should be constantly updated as well.

Objective To investigate the effects of silencing of the human cerebral 21 .5 kDa myelin basic protein (MBP) gene on the proliferation and apoptosis of the glioma U251 cells .Methods The 21 .5 kDa MBP sequence‐specific short hair‐pin RNA (shR‐NA) recombinant plasmids pGenesil‐1‐MBP‐3 were transfected into the human glioma cell line(U251) ,the cells of U251 was used as MBP silencing group ,the cells transfected with negative control plasmids used as negative control group ,and the cells transfected with liposomes used as blank control group .Real‐time PCR and Westernblot were used to detect the expression levels of the 21 .5 kDa MBP mRNA and protein in each group ,and the cell proliferation curve was measured by CCK‐8 assay ,the apoptosis rate was a‐nalysised by Flow cytometry .Results Both the mRNA and the protein expression levels of the 21 .5 kDa MBP of MBP silencing group were significantly lower than those in the control groups (P<0 .05);the cellular proliferation activity of the MBP silencing group decreased significantly (P<0 .05)while the cellular apoptotic rate increased significantly (P<0 .05) .Conclusion Silencing of the human cerebral 21 .5 kDa MBP gene may playa dual role in the inhibition of proliferation and the promotion of apoptosis of the glioma U251 cells .

Objective To explore the clinical value of clara cell protein 16 (Cc 16) in the early diagnosis of ARDS in critically ill patients.Methods A total of 55 critically ill patients admitted between March 2013 and December 2013 in the Intensive Care Unit were enrolled for study.The inclusion criteria were as follows:sepsis,pneumonia,multiple injuries,patients after emergency or elective operation and non-cardiogenic diseases,whereas the exclusion criteria were cardiogenic pulmonary edema,age ≤ 18 years or≥80 years and disease course prolonged over one week.The level of serum Cc16 was detected with enzyme linked immunosorbent assay (ELISA).In addition,data of other biochemical examinations,the Acute Physiology and Chronic Health Evaluation (APACHE]Ⅱ) score and the relevant medical data were documented.The patients were divided into ARDS groups and non-ARDS groups based on clinical data met Berlin definition.Results The sensitivity and specificity of serum Cc16 for diagnosis of ARDS were 92％ and 80％,respectively with the area under the curve being 0.92,which were better than those of APACHE Ⅱ score,D-dimer,C-reactive protein,N-terminal pro-brain natriuretic peptide and serum albumin detected by the means of receiver operating characteristic curve,and cut off value was 20.62 ng/L.The bivariate analysis showed there was negative correlation between Cc16 and oxagenation index in ARDS patients and the Pearson correlation coefficient of serum Cc16 with oxygenation index was r =-0.342 (P =0.04).The results of one-way analysis of variance showed difference in level of Cc16 between subgroups (F =15.76,P =0.005 17).The level of Ccl6 in severe ARDS group was (64.18 ± 12.95) ng/L which was higher than that in mild ARDS group (35.87 ± 11.28) ng/L (P =0.001 14),and in moderate ARDS group (38.66 ± 20.14) ng/L (P =0.004 9),and in non-ARDS group (16.72 ± 8.74) ng/L (P =0.000 32).There was no statistically significant difference in Cc16 level between mild ARDS group and moderate ARDS group (P =0.682).The level of serum Ccl6 did not correlate with type or days of respiratory ventilation support,28-day survival rate or 120-hour survival rate and days of ICU stay and hospital stay.Conclusions The diagnostic value of serum Cc16 is very high in determining the presence and severity of ARDS in addition to the Berlin criteria in critically ill patients accurately assessing degree of lung injury.

Objective The effect of combined treatment of statins and calcium channel blockers(CCB) in elderly patients with isolated systolic hypertension(ISH) are not well understood.The purpose of the present study was to assess the additive effect of benidipine-atorvastatin combination therapy in old patients with ISH.Methods Ninety patients with ISH were randomized to receive: placebo(n=15),benidipine treatment(4-8 mg/d,n=25),atorvastatin(20 mg/d,n=25) and benidipine plus atorvastatin treatment(4-8 mg/d+20 mg/d,n=25) for 5 months.Serum concentrations of IL-6,IL-8,hsCRP,flow-mediated dilatation of the brachial artery,urine microalbumin,left ventricular mass index(LVMI),carotid intima-media thickness(CIMT),BP and plasma lipids profiles were examined before and after treatment.Results After 5-months of treatment,the combination treatment significantly reduced IL-6(IL-6 reduction magnitude,combination group: 6.5+6.3 ng/L vs benidipine group: 3.1?3.2 ng/L vs atorvastatin group: 3.3?2.3 ng/L,P

A 28-year-old male patient presented with a 4-year history of a solitary brown mass, and a 1-year history of multiple small papules on the left chest. Skin examination showed a quasi-round brown firm mass measuring about 1.2 cm × 1.1 cm × 1.0 cm in size on the left chest, and several brown papules with diameters ranging from 3 to 5 mm on the right side of the mass; no enlarged lymph nodes were detected in the left axilla on palpation. The mass and papules were completely resected, and histopathological examination showed clustered nevus cells in the superficial dermis of the mass and small papules, and the diagnosis of intradermal nevus was considered. There was a desmoplastic nodule in the mass, nevus cells were scattered among the fibers in the nodule, and giant nevus cells were also observed; the nevus cells in the nodule were relatively larger, epithelioid or spindle-shaped with round or spindle-shaped nuclei, obvious nucleoli, and rare mitotic figures. Immunohistochemical study showed that the nevus cells in both the intradermal nevus and proliferative nodule were positive for S100; the nevus cells in the superficial dermis of the intradermal nevus were positive for Melan-A and HMB45, while the nevus cells in the proliferative nodule were negative for Melan-A and HMB45; both the intradermal nevus and proliferative nodule tissues showed a Ki-67 index of 1%, positive staining for CD34, but negative staining for P16 and P63. Finally, the patient was diagnosed with intradermal nevus associated with desmoplastic nodule.

Epilepsy is one of the most common chronic diseases of the central nervous system,many epilepsy patients need lifelong medication.Epidemiological studies have shown that 3‰-5‰ neonates born by women suffering from epilepsy.Treatment become more challenging because not only the patients themselves but also the breastfed in fants should be taken into consideration.This paper reviewed how to choose lactation antiepileptic drug.In short,choosing drugs which transport less to milk and have less side effects to infants,using the lowest effective dose and avoiding combination if possible can ensure the safety of breastfeeding.

Aim The protective effect of total salvianolic acids (Sal) on cerebral hypoxia inmice was studied. Methods Acute cerebral hypoxia was induced by sodium nitrite scand decapitation.The effect of Sal on acute cerebral hypoxia in mice and neuronalhypoxia injury induced by sodium dithionite in primary cultures were ob-served. Results Sal in the doses of 10, 20 mg?kg-1 iv protected mice against theacute cerebral hypoxia and inhibited the production of lipid peroxidation in brain tis-sue of mice caused by cerebral hypoxia. Sal in the doses of 1~10 ?g? L-1 reduced therate of cell death and the content of MDA and lowered LDH content in extra-cellularbathing media in oxygen deprived cortical cultures.Conclusions Sal protects miceagainst cerebral hypoxia by suppressing the generation of lipid peroxide.

Objective To investigate the characteristics and plausible mechanisms of attention network impairments in hyperthyroid patients.Methods 34 hypertyroid patients and 33 normal controls performed the attention network test (ANT),which was used for assessing three components of attentional networks including alerting,orienting,and executive control.Results The mean scores for alerting and orienting networks were significantly shorter (P ＜ 0.01) in hyperthyroid patients (respectively,(20.00 ± 22.47) ms,(35.26 ± 22.65) ms)than those in normal controls (respectively,(35.70 ± 17.62) ms,(50.61 ± 23.66) ms).The mean reaction time for executive control network was significantly longer(P ＜ 0.01) in hyperthyroid patients((116.71 ± 40.36)ms)than those in controls ((93.00 ± 29.34)ms).Triiodothyronine(T3) and thyroxine(T4) were positively correlated with the scores for executive control network (respectively,r=0.350,P＜ 0.05; r=0.417,P＜ 0.05) in hyperthyroid patients,whereas no relationship was found between thyroid stimulating hormone(TSH) and the value of executive control network.T3,T4 and TSH were not correlated with the value of alerting and orienting network in hyperthyroid patients.Conclusion Hypertyroid patients have extensive impairments in various kinds of attentional network,rather than a specific deficit.The recession of executive control network accompanies with enhancement of serum levels of T3,T4 in hyperthyroid patients.
