Pulmonary edema frequently occurs after severe burn. It not only impairs pulmonary function directly, but also can induce or exacerbate other pulmonary complications such as lung infection, acute lung injury ( ALI), and ARDS. Extravascular lung water (EVLW) is closely related to the pulmonary edema. Dynamical monitor of EVLW has been used to predict and quantify the degree of pulmonary edema clinically. This review focuses on the recent progresses at home and abroad on the formation mechanism, monitoring approach, and prevention and treatment of EVLW after severe burn injury.

ObjectiveTo summarize the clinical characteristics of pt osis,one of complications after double eyelid blepharoplasty, and to explore i ts causes and attempt for the resolutions. MethodsThe clinica l symptoms were divided into three types based on the degrees of the ptosis afte r double eyelid blepharoplasty. The causations in 25 cases of different degree o f ptosis after double eyelid blepharoplasty were investigated and analyzed durin g operations. The local adhesive deformities were analyzed so as to take differe nt resolutions for the complication. Results It seemed that th e operative damage to the aponeurosis was the main reason for the complication. So it caused the scar adhesive deformities between the palpabralis aponeurosis a nd the orbital membrane or the skin of upper eyelid, resulting in the difficult y of the palpabralis muscle's contract and unablility of the muscle function in different degrees. Conclusion The ptosis can surely be av oided if we have good knowledge about the mechanism of double fold formation and the anatomy of eyelids and perform the operation meticulously.

Objective To observe the oculocardiac reflex during the ocular plasty and to study its possible mechanism. Methods A total of 132 cases were studied by dynamic electrocardiography to analyze the changing of heart rate before and after operations. Results Heart rate decreasing by over 10 times during operations was regarded as the positive standard of the oculocardiac reflex. Of all cases the oculocardiac reflex appeared in 41 cases and 53 times were observed including of continual two times happened in 6 cases. In all the reflex ,9 cases was observed in injection of anaesthetic, 5 cases in pulling eyelids, the orbicular muscle and the palpabralis muscle, 21 cases in resecting orbital fats,6 cases in stressing the eyeball after operations. The incidence of oculocardiac reflex was 31.1%. Conclusion Some steps in the process in ocular plasty are more possible to elicit the reflex, such as dragging peripheral eyeball muscles,stressing eyeball and pulling eyelid. The reflex will result in heart rate decreasing, heart rhythm and respiratory changing,even render heart to sudden stop . Therefore, we should operate gentlely and accurately,and also avoid overly stress on eyeball to elicit the oculocardiac reflex.

Objective To explore the mechanism of sulfotanshinone sodium injection in treatment of patients with sudden deafness (SD).Methods Sixty patients with SD admitted to the Department of Otorhinolaryngology of Wuxi Traditional Chinese and Western Medicine Hospital from January to December 2016 were enrolled, and they were randomly divided into a study group and a control group (each 30 cases). The same basic treatment was given in the two groups, the patients in the study group were treated with sulfotanshinone sodium 40 mg intravenous (IV) drip, while the patients in the control group were treated with vinpocetine sodium chloride 20 mg IV drip, once a day for consecutive 14 days to complete a therapeutic course, and two courses were carried out in bothgroups. Before and after treatment, the changes of hearing threshold, indexes of hemorheology and immune function were compared between the patients in the two groups, and the clinical efficacy and adverse reactions in the two groups were observed.Results After treatment, the hearing threshold, hemorheology indexes, immune function index of CD8+ were significantly lower than those before treatment, while the CD3+, CD4+, CD4+/CD8+ ratio were significantly higher than those before treatment in the two groups, and the above changes of indexes were more obvious in the study group than those in the control group hearing [threshold (dB): 16.63±2.04 vs. 17.15±1.88, plasma viscosity (PV, mPa·s): 1.27±0.14 vs. 1.31±0.11, whole blood middle shearing viscosity (mPa·s): 4.77±0.33 vs. 4.95±0.28, whole blood high shearing viscosity (mPa·s): 3.86±0.25 vs. 4.00±0.31, erythrocyte aggregation index (EAI): 1.57±0.29 vs. 1.72±0.34, CD3+: 0.70±0.05 vs. 0.64±0.05, CD4+: 0.43±0.04 vs 0.37±0.03, CD8+: 0.32±0.04 vs. 0.34±0.03, CD4+/CD8+: 1.36±0.32 vs. 1.18±0.27]; the degree of whole blood low shearing viscosity (mPa·s: 6.72±0.80 vs. 7.01±1.13) and hematocrit (HCT: 0.38±0.04 vs. 0.40±0.03) decreasing weremore significant in the control group than those in the study group. The total effective rate was higher in study group than that in the control group [86.67% (26/30) vs. 83.33% (25/30)], but the difference between the two groups was not statistically significant (P > 0.05); the incidence of adverse reactions in the study group was markedly lower than that in the control group [3.33% (1/30) vs. 20.00% (6/30),P < 0.05].Conclusions Sulfot anshinone sodium injection can effectively enhance the SD patients' hearing, and improve their hemorheology indexes and immune function; the therapeutic results of sulfotanshinone sodium injection in safety and improvement in immune function are superior to those of vinpocetine sodium chloride injection.

Objective To explore the value of glypican-3(GPC-3)mRNA and paternally expressed 10(PEG10)mRNA in peripheral blood in diagnosis of metastasis in hepatocellular carcinoma(HCC). Methods With SYBR Green I as fluorescence signal,real-time fluorescent quantitative reverse transcription-polymerase chain reaction was employed to detect the expression of GPC-3 mRNA and PEG10 mRNA in peripheral blood from patients with HCC with metastasis(n=8),HCC without metastasis(n=12)and hepatic cirrhosis(n=11),and receiver operator characteristics curve(ROC)and specific parameters were adopted to analyse their value in predictive and exclusive diagnosis. Results The expression of GPC-3 mRNA and PEG10 mRNA in HCC with metastasis was significantly higher than that in HCC without metastasis and in hepatic cirrhosis(P<0.05),while there was no significant difference in the expression of GPC-3 mRNA and PEG10 mRNA between HCC without metastasis and hepatic cirrhosis.In single test,the sensitivities in the differential diagnosis between HCC with metastasis and HCC without metastasis were 66.7%for GPC-3 mRNA and 72.2%for PEG10 mRNA,and the specificities were 91.7%and 91.7%.respectively.The areas under ROC were 0.748 for GPC-3 mRNA and 0.812 for PEG10 mRNA.With two markers in parallel test,the sensitivity,specificity,negative likelihood and diagnostic accuracy were 90.7%,84.O%,0.11 and 83.3%,respectively.In serial test,the sensitivity,specificity,positive likelihood and diagnostic accuracy were 60.5%,98.7%,45.5 and 73.3%,respectively. Conclusion Detection of GPC-3 mRNA and PEG10 mRNA in peripheral blood may help to predict blood metastasis and extrahepatic metastasis of HCC,and PEG10 mRNA works better than GPC-3 mRNA.The serial test of GPC-3 mRNA and PEG10 mRNA is helpful to the predictive diagnosis of peripheral blood metastasis of HCC.
