Objective To assess the value of pulmonary vascular permeability index in differentiating acute lung injury (ALI) from cardiac pulmonary edema. Methods Critically ill patients with acute pulmonary edema were included from May, 2004 to September, 2008. Patients were divided into two groups, the ALI group and the cardiac pulmonary edema group (C group). Pulmonary vascular permeability index (PVPI) , intrathoracic blood volume (ITBVI) were determined by pulse indicator continuous cardiac output(PiCCO) system. Results ( 1 ) Thirty-four patients were enrolled, 22 cases in ALI group and 12 cases in C group. (2) The PVPI in patients of ALI group (2.7 ± 1.4) was higher than that of C group (1.9 ±0.6 ;P<0.05). EVLWI and ITBVI did not have the significant difference between the two groups (P >0. 05). (3) PVPI was positively correlated with EVLWI(r = 0. 762) , negatively correlated with PaO2/ FiO2(r= -0.478). (4)ARDS was diagnosed in 13 cases, including 8 pulmonary cause(ARDSp) and 5 extra-pulmonary cause ( ARDSexp). PVPI, EVLW/ITBV and EVLWI of patients with ARDSexp were obviously higher than those with ARDSp. Conclusions PVPI may be useful for differentiating the types of pulmonary edema in the critically ill.

Objective To investigate the modulatory effects of glycyrrhizin (GL) on the expressions of nu-clear factor kappa B (NF-κB), glucocorticoid receptor (GR) and cytokines in serum, and to explore the protective mechanism of GL in acute lung injury (ALI) induced by lipopolysaecharide (LPS). Method Twenty-four male Sprague-Dawley rats were randomly(random number) divided into three groups (n = 8 in each) : normal group, ALI group and GL treatment group. Rats in the ALI group and GL treatment group were administered with LPS (5 mg/kg) intravenously. In GL treatment group, rats were treated with GL (20 mg/kg) one hour before LPS injec-tion. The animals were sacrificed 4 hours after injection of LPS, and then the lung wewt/dry ratio and PaO_2 were measured, the histopathology of lung injury was observed under light microscope, the expressions of NF-κB mRNA and GR mRNA in lung tissues were detected by using RT-PCR, and the levels of NF-κB protein and GR protein were determined by using Western blot. The levels of TNF-α and IL-10 in serum were observed by using ELISA.Data were analyzed with SPSS version 13.0 software, and means were compared with analysis of variance and Stu-dent-Newman-Keuls test. Results (1) TNF-α levels in normal group, ALI group and GL treatment group were (43.96±7.57), (153.68±20.42), and (87.23±7.52) ng/L, respectively, and IL-10 levels were (24.72±8.03), (42.48±6.81) and (58.33±9.62) ng/L, respectively (F = 183.70, all P <0.01). (2) NF-κB mRNA expressions in normal group, ALI group and GL treatment group were (0.432±0.085), (3.414±0.521) and (1.894±0.272), respectively, and NF-κB protein levels were (45.6±7.3), (254.7±16.4)and (133.5 ±11.7) ng/L, respectively, and comparison between groups showed statistical significant (F = 187.82 and 1466.53, ALL P < 0.01). GR mRNA expressions in normal group, ALI group and GL treatment group were (0.434±0.013), (0.152±0.025) and (0.308±0.033), respectively, and GR protein levels were(54.6±6.5), (11.5±2.3)and (28.2±5.6) ng/L, respectively (F = 246.00 and 260.92, all P < 0.01). (3) Com-pared with normal group, infiltration of PMNs, capillary congestion and swelling were found in ALI group, and treatment with GL could attenuate the lung injury. Conclusions Glycyrrhizin has a protective effects on rats with ALI induced by LPS maybe through down-regulating the expressions of NF-κB mRNA and TNF-α mRNA, and up-regulating the expression of GR mRNA and level of IL-10 protein.

BACKGROUND:The electrospinning technique has been used to prepare biological scaffolds to simulate nano-fiber structure of extracelular matrix; therefore, widespread attention has been paid to the electrospinning technique in the field of regenerative medicine and tissue engineering. OBJECTIVE: To review the articles about increasing electrospun nanofiber scaffold porosity, enlarging pore diameter, promoting cel infiltration with related technologies, in order to discover the most practical and economical technology. METHODS:The first author retrieved CNKI database, Wanfang database and PubMed with the keywords of “cel infiltration, 3D scaffold, electrospinning” in Chinese and English, respectively. Literature retrieval period was from January 2004 to October 2014. RESULTS AND CONCLUSION:Electrospinning technology is the most effective method for preparation of nanofiber scaffolds. Electrospinning scaffolds as tissue engineering scaffolds have become an issue of concern in the basic research year by year. However, the internal nano-scale pore of nanofiber scaffolds limits the cels to grow on the surface, so recent research has been focused on highly porous three-dimensional structure which can promote the permeable growth of cels instead of two-dimensional scaffolds. Several techniques have been used, which go from the adjustment of materials and speed of electrospinning to the applications of various kinds of complicated machines. However, the existing researches are stil not mature and stable, the majority of which are applied onlyin vitro as cel implantation or subcutaneous implantation in smal animals. The above-mentioned methods stil need long-term comparative studies to confirm the feasibility in the tissue-engineered repair of organs.

OBJECTIVETo analyze epidemiological characteristics of norovirus variant of GII.4 Sydney from January 2012 to June 2014 in sentinel hospitals of Guangdong province, as well as the outbreaks caused by norovirus variant of GII.4 Sydney.
METHODSDuring January 2012 to June 2014, a total of 10 750 fecal samples were obtained from 22 hospitals of surveillance sites in Guangdong province. Those samples were sent to the local municipal CDCs for extracting and detecting norovirus nucleic acid. Then, all the positive samples were delivered to Guangdong provincial CDC that used Random Number Method to draw 855 positive samples for norovirus genotyping, and 690 samples were successfully sequenced. Chi-square tests were used to compare norovirus infection status of diarrhea cases in different age groups as well as during different periods. Epidemiological data of 13 outbreaks which were caused by norovirus variant of GII.4 Sydney from January 2012 to June 2014 were collected from the Public Health Emergency Management Information System of Guangdong Province, and the epidemiological characteristics were analyzed.
RESULTSThe norovirus variant of GII.4 Sydney was first detected in August 2012 and the detection rate was 13/15 in November 2012. During November 2012 to January 2013 (period T1), the norovirus positive rate of each month was 23.8% (100/421), 15.9% (61/383) and 19.2% (95/495), respectively. During November 2013 to January 2014 (period T2), the norovirus positive rate of each month was 17.0% (90/529), 8.7% (37/426) and 11.2% (46/409), respectively which were significantly lower than that of period T1 (χ² alue was 6.65, 9.93 and 10.74. P value was 0.010, 0.002, and 0.001, respectively). In period T1, the norovirus positive rate of people ages 15 and older was 26.3% (143/543) and the rate of people under 15 was 14.9% (113/756) (χ² = 2.90, P < 0.001). In period T2, the norovirus positive rate of people ages 15 and older was 10.1% (52/516) and the rate of people under 15 (14.3% (121/848)) (χ²= 5.09, P = 0.024). The foodborne transmission was the infection source for ten of thirteen outbreaks.
CONCLUSIONThe norovirus variant of GII.4 Sydney was first detected in August 2012. The epidemic began to occur in the community since November 2012, and the strength of the epidemic declined 1 year later. The foodborne transmission was the main infection sources for the outbreaks caused by norovirus variant of GII.4 Sydney.

Informatization plays an important role in the management of clinical diagnosis and treatment. However, due to the specialty of the discipline, the informatization construction of critical care medicine(CCM)is faced with such problems as the inefficient application of data, the low compliance of diagnosis and treatment operation, and the lack of intelligent quality control tools. The authors discussed the new mode of CCM information management based on data driven. By upgrading clinical information system, establishing single disease control system, introducing comprehensive intelligent analysis platform and building open remote platform, the bottleneck of CCM informatization was broken. The information collection and interaction in ICU was realized, the automatic monitoring and early warning of diagnosis and treatment process was realized, the operation of medical staff according to the guidelines was effectively improved, and the ability of diagnosis and treatment and management efficiency was improved.Furthermore, the homogenization of regional critical medical information could be promoted.

OBJECTIVETo evaluate the cost-effectiveness of two breast cancer screening modalities conducted in Minhang district of Shanghai, China.
METHODSAn organized and an opportunistic breast screening programs were implemented among women aged 35-74 years in Minhang district of Shanghai between May 2008 and Oct 2010, and were compared with the results obtained without screening. Costs related to screening were obtained by access to finance data of the screening programs, and costs of first treatment were collected through patient survey and medical reimbursement system query. Information on breast cancer stage was obtained from Shanghai Cancer Registry and confirmed by medical chart review. The effectiveness of screening was evaluated by breast cancer stage improvement.Cost-effectiveness ratios (CERs) were computed as costs of gaining a stage improvement from a specified screening strategy when compared with the results obtained without screening. Incremental cost-effectiveness (ICER) which compares the two screening strategies was calculated by dividing the difference in total net costs and the difference in stages improved between the two screening strategies.
RESULTSThirty-five, one hundred and ninety-three and four hundred and seventy-nine breast cancer cases were identified in the organized screening, opportunistic screening and control groups, with an early detection rate of 46.9%, 40.7% and 38.9%, respectively. The costs of screening were 208 yuan per person or 72 453 yuan per case detected in the organized screening group and were 21 yuan per person or 11 640 yuan per case detected in the opportunistic screening group. The total cost was 103 650 yuan per case in the organized screening group, significantly higher than 50 712 yuan in the opportunistic screening group and 35 413 yuan in the control group. However, the average direct medical cost was significantly lower in the organized screening group than that in the opportunistic screening group and control group, with median costs of 11 024 yuan, 13 465 yuan and 14 243 yuan per case, respectively (P<0.001). The additional cost per case detected was 68 237 yuan for the organized screening and 15 299 yuan for opportunistic screening. The CERs were 135 291 yuan and 152 179 yuan per stage improved in the organized screening and opportunistic screening relative to the control group, with ICER of organized versus opportunistic screening being 131 086 yuan per stage improved.
CONCLUSIONSThe organized screening modality and the opportunistic one are both effective in early detecting breast cancer in Chinese women. The organized screening costs more than opportunistic screening, but with a better cost-effectiveness. It may be used as an option in economically developed areas of China.

OBJECTIVETo investigate the value of C-reactive protein (CRP) on transplantation day in predicting early post-transplant infections and outcomes of allogeneic hematopoietic stem cell transplantation (allo-HSCT).
METHODSWe retrospectively analyzed the clinical data of 78 recipients undergoing allo-HSCT. The clinical reference value of CRP on transplantation day was determined, and its sensitivity and specificity for diagnosing bacteremia was analyzed using receiver-operating characteristic curve (ROC). The incidence of transplant-related complications, overall survival, and relapse rate of the patients were analyzed with respect to the CRP level.
RESULTSThe clinical reference value of CRP for diagnosing bacteremia was 23.3 mg/L (AUC=0.735 [95% CI: 0.623-0.848], P=0.001), which had a diagnostic sensitivity and specificity of 0.793 and 0.592, respectively. Compared with the patients with low CRP levels, the patients with high CRP levels tended to have delayed neutrophil reconstitution and platelet engraftment by 0.71 days (P=0.237) and 4.09 days (P=0.048), respectively, and had a significantly higher incidence of bacteremia (17.1% vs 53.5%, P=0.001) and CMV viremia (37.1% vs 72.1%, P=0.003) within 100 days following the transplantation; the incidences of EBV viremia, pulmonary invasive fungal infection, or acute graft versus host disease (aGVHD) showed no significant difference between the two groups (41.9% vs 22.9%, P=0.094; 14.0% vs 5.7%, P=0.285; 51.2% vs 45.7, P=0.656, respectively). During the follow-up for a median of 318 (7-773) days in high-CRP group and for 299 (78-747) days in low-CRP group, the high-CRP group showed a significantly lower 2-year overall survival than the low-CRP group (42.5% vs 78.4%, P=0.022), and tended to have a higher 2-year cumulative relapse rate (52.3% vs 19.8%, P=0.235). Logistic multivariate analysis identified a high CRP level on transplantation day as the independent risk factor for post-transplant bacteremia within 100 days (OR=5.090 [95% CI: 1.115 -23.229], P=0.036).
CONCLUSIONA high CRP level on transplantation day can be indicative of a high risk of early post-transplant bacteremia and CMV viremia and also a poor prognosis following allo-HSCT.

Objective To explore the practical feasibility of the weaving technique for pectus carinatum. Methods From January 2011 to December 2018, a total of 51 patients with pectus carinatum, including 47 males and 4 females at age of 9-29 (13.7±2.9) years, were applied with minimally invasive waving technique for the correction. The steel plate was inserted through the subcutaneous layer, intercostal space and over the sternal surface under direct thoracoscopic vision. The number of implanted steel plates was determined by the degree of chest wall deformity. The steel plate was removed 2 years after surgery. Results All the operations were successfully completed, the average operation time was 63.9±15.8 min, the amount of bleeding was 19.8±8.8 mL, and the duration of postoperative hospitalization was 4.6±1.6 d. The adverse events included intercostal artery injury (n=2), pneumothorax (n=4), pleural effusion (n=3) and skin rupture (n=1). And there were 29 patients of moderate pain (numerical rating scale 4-6 points) on the first day after surgery, but no patient was asked to remove the steel palate due to intolerable discomfort. All patients were followed up after plate placement. Of the 51 patients, the plates were removed in 37 patients until 2 years after placement, and the duration of postoperative hospitalization was 1.4±0.5 d. After 33 (1-48) months of routine follow-up after the removal of the plate, 22 patients achieved excellent outcomes and 9 patients with good outcomes. Besides, there were 5 patients with fair outcome and 1 patient with poor outcome. No adverse effect was found in growth and development after the steel plate placement. Conclusion Minimally invasive weaving technique is a safe, feasible, effective and individualized operation for pectus carinatum with substantial thoracic reconstruction.
