High flow nasal cannulae(HFNC),a new mode of noninvasive respiratory support,by high-flow nasal cannula transports humidified,warmed and high flow maxed oxygen above the flow of 1 ~2 L/min. In the application of Neonatology,the higher oxygen flow and the smaller body type of newborn cause the stron-ger the expansion pressure by HFNC,and following the change of the amount of oxygen leaking along the con-duit.The effect of HFNC in improving respiratory parameters (such as neonatal tidal volume and respiratory function)was similar to nasal continuous positive airway pressure(NCPAP),but the effectiveness is limited to the flow less than 2L/min.A growing number of evidence suggests that HFNC as an alternative method for pre-term non-invasive alternative ventilation is available,but the effect and safety of applications in preterm still need further research.HFNC is not recommended popularized in preterm until more randomized trials to confirm.

This study was aimed to compare different preparation methods of Wei-Chang Fu-Yuan (WCFY) De-coction, which is a self-made traditional Chinese medicine (TCM) decoction of our hospital, through the investiga-tion of difference in recovery time of gastrointestinal function after gynecological abdominal surgery. A total of 120 cases after gynecological abdominal surgery in our hospital between 2011 and 2012 were randomly divided into the treatment group and the control group, with 60 cases in each group. The hospital self-made WCFY Decoction was given to patients 8 hours after surgery in the treatment group and control group. Decoctions given to two groups were prepared with different methods. Decoction given to the treatment group was by the decoction ma-chine of multiple decoctions preparation. Decoction given to the control group was prepared as the traditional sin-gle dose decoction. The first anus flatus time was observed in both groups. The results showed that the flatus time of treatment group was 16 h and that of the control group was 13 h. The flatus time of patients from two groups was in skewed distribution, so the distance between the median and quartile was used to describe. The non-para-metric tests (Kolmogorov-Smirnov method) were used in the comparison of flatus time of two groups. There was statistical significance between two groups (P < 0.05). It was concluded that different preparation methods affect the clinical efficacy of WCFY Decoction. Compared with the traditional single dose decoction, the fist flatus time was postponed 3 hours by the decoction machine of multiple decoctions preparation. Therefore, with the widely using of decoction machine of multiple decoctions preparation today, the function of decoction machine should be improved and the program should be perfected in order to increase the clinical efficacy of this preparation method.

Objective To evaluate the value of immature granulocytes count in diagnosing and monitoring the systemic inflam-matory response for patients with systemic inflammatory response syndrome,and to provide a new indicator of systemic inflammato-ry response.Methods 207 patients suspected of systemic inflammatory response syndrome were enrolled.The dynamic changes of immature granulocytes counts and the disease situation were recorded for all subjects.The blood samples were collected in vacuum tubes with EDTA-K2 anticoagulant.Blood cell count and immature granulocytes count were performed in Sysmex XE-2100 hema-tology analyzer.The determination of C-reactive protein and procalcitonin were also completed.The performance of immature granu-locytes in diagnosing systemic inflammatory response syndrome was evaluated by receiver operating characteristic curve analysis. Results The area under the curve of immature granulocyte count (IG #)was 0.78 in diagnosing systemic inflammatory response syndrome,with a sensitivity of 62.2 % and a specificity of 73 % at IG #> 0.1 65.The area under the curve of immature granulo-cyte percent (IG%)was 0.771 in diagnosing systemic inflammatory response syndrome,with a sensitivity of 54.1 % and a specifici-ty of 94.6 % at IG%>2.55 %.The area under the curve of C-reactive protein was 0.71 6 in diagnosing systemic inflammatory re-sponse syndrome,with a sensitivity of 67.6% and a specificity of 75.7 % at C-reactive protein> 64.15 mg/L.The area under the curve of procalcitonin was 0.772 in diagnosing systemic inflammatory response syndrome,with a sensitivity of 75.7 % and a speci-ficity of 70.3 % at procalcitonin> 0.33 mg/L.Conclusion Immature granulocyte count is beneficial for the diagnosis and the as-sessment of prognosis of systemic inflammatory response syndrome.

Objective This study was designed to determine the influence of acute ethanol intoxication (AEI) on brain edema and aquaporin-4(AQP-4) levels after traumatic brain injury(TBI) in rots. The underlying mechanism was also investigated. Method Severe traumatic brain injury models were made using the Feeny method; acute ethanol intoxication models were established by gavagy. One hundred and ninety-two male SD rats were randomly divided(random number) into four groups, namely the sham operation group(A ), the acute ethanol intoxication group( B ), the traumatic brain injury group(C) and the combination of acute ethanol intoxication with traumatic brain injury group(D). Each group was further divided into four sub-groups according to the time interval between injury and death of the rats. After brain tissue was fixed by affusing paraformaldehyde, the expression of AQP-4 was detected by immunohistochemistry. Water content was detected by dry-wet analysis, and AQP-4 mRNA and protein were detected by RT-PCR and western blotting respectively after the brain tissue was got by rapid decapitation. Data were analyzed by one-way ANOVA. Results The water content of brain tissue and expression level of AQP-4 were not significantly different between groups A and B( P > 0.05); however both were significantly increased in groups C and D relative to group A( P < 0.05). The water content of brain tissue in group D increased by mere than that in group C( P < 0.05), while the expression level of AQP-4 in group D was lower than that in group C(P<0.05). Conclusions Acute ethanol intoxication inhibited the expression of AQP-4,which induced a more severe cerebral edema after traumatic brain injury.

Objective To dynamically observe the effect of mild hypothermia on concentration of plasma S-100B protein in patients with acute severe brain injuries so as to further explore its role in treat-ment of acute severe brain injury. Methods A total of 120 patients with acute severe brain injuries were randomly divided into mild hypothermia group and general group. The patients in mild hypothermia group were treated with mild hypothermia besides conventional therapy, with maintenance of rectal tem-perature at 33℃-35℃ for 3-5 days. Serial concentration of S-IOOB protein in serum was measured in all patients from 6 hours to 6 days after hospitalization. GOS evaluation was done three months after treat-ment. Results The concentration of S-100B protein in serum of mild hypothermia group and general group was significantly higher than of normal group (P <0.05), with significant lower level in mild hypo-thermia group than general group(P <0.05). Mild hypothermia could improve prognosis of patients with acute severe brain injury. Conclusions Early use of mild hypothermia can decrease concentration of S-100B protein in serum, protect neurofunction and improve prognosis, as may be related to its function in alleviating damnification brain cell inflammation reaction mediated by S-100B protein.

Objective To observe the CT features of ovary Brenner tumor. Methods CT manifestations of 5 patients with ovary Brenner tumor confirmed with pathology and clinical follow-up were retrospectively analyzed, and the masses were described for location, size, configuration, enhancement pattern, presence of calcification and metastatic spread. Results There were 7 tumors in 5 patients, 3 patients had unilateral tumors and 2 had bilateral Brenner tumors (left side 3 and right side 4), with tumor size ranging from 1.52 to 16.25 cm (mean 7.36 cm). Five masses in 4 patients were benign, 2 (bilateral tumors in 1 patient) were malignant. All tumors had well-defined margin. One patient with bilateral benign tumors had large pleural effusion and seroperitoneum. Five tumors in 4 patients (5/7, 71.43%) were solid and had calcification, 2 tumors in 1 patients (2/7, 28.57%) were mainly cystic, with septa in the tumors. The solid part of all tumors were inhomogeneous and had mild enhancement. Conclusion CT findings of ovary Brenner tumor have some characteristics. Combining with clinical manifestations, CT is helpful for the diagnosis of ovary Brenner tumor.

Objective To explore the optimal power of experimental pancreatic endoscopic ultrasonography (EUS)-guided radiofrequency ablation (RFA) therapy.Methods Six healthy live minipigs were randomly divided into two groups according to random number table,which received RFA under EUS or in laparotomy.Each pig in each group was randomly allocated to received RFA at different power (5 W,10 W,15 W).The impedance was monitored and the time for each therapy was recorded.The width diameter of coagulation necrosis from RFA was measured by EUS and gross pathology.Results RFA was completed in all pigs smoothly with stable life signs and without complications.Gross and micro pathologic observation confirmed formation of coagulation necrosis lesions.The width diameter of lesions from EUS-RFA was similar to that from surgery RFA,both having a maximum value at 10 W power (11 nun VS 10 mm).Conclusion The optimal power of experimental pancreatic EUS-RFA in pig is 10W,which should be further explored for the clinical purpose.
