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 .

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.

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.
