Objective To gather observational data on resting energy expenditure(REE)of children with newly diagnosed malignant solid tumor, and to examine factors that might be relevant to their energy expenditure change. Methods It is a retrospective study. Data from sixty-one patients with newly diagnosed malignant tumor admitted to department of pediatric surgery in Xinhua Hospital were reviewed in this study. Resting energy expenditure was measured by indirect calorimetry. Patients with benign tumor admitted during the same period were used as the control group. Results The difference of percentage of patients with normal, decreased, or increased REE between benign and malignant groups was not significant(χ2 = 0.466, P = 0.792). Patients with one or more gastrointestinal symptoms had higher percent of Pre-REE compared with patients without any gastrointestinal symptoms, but no significant difference existed(119.8±80.4 vs 91.1±27.2, Z = 0.746, P = 0.456). Different tumor types were associated with different effects on REE. There was no significant difference in REE levels between patients with decreased diet intake and those without(Z = 0.528, P = 0.598). Conclusions It is confirmed that not all patients with malignant tumor have an increased REE. Moreover, the tumor site might be an independent factor affecting patients' REE level.

BACKGROUND:Studies have shown that ankle-foot orthosis can increase the feedback on the input information from receptors in the skin of the foot and leg to improve the ankle joint position sense, and promote brain function reorganization.
OBJECTIVE:To systematical y evaluate the effect of ankle-foot orthosis on the improvement of walking in hemiplegic patients.
METHODS:The Chinese Biomedical Literature Database, CNKI, WanFang Data and VIP database were searched for reports of randomized control ed trials of ankle-foot orthosis to improve walking ability in hemiplegic patients, from the date of establishment of each database to June 2013. The randomized control ed trials which met the criteria were included for the Meta-analysis.
RESULTS AND CONCLUSION:A total of 9 randomized control ed trials involving 456 patients were included. Meta-analysis showed that, compared with conventional treatment and drug therapy, ankle foot orthosis via the continuous treatment shows certain advantages to improve lower extremity motor function in hemiplegic patients, life skil s and 10-meter maximum walking speed. Due to a limited number of included documents, the remaining indicators such as walking speed, stride difference and balance function were only for appropriate descriptive analysis. The results suggested that, by improving abnormal gait, walking speed, stride frequency, gait cycle, space asymmetry, ankle muscle spasms and balancing, the ankle-foot orthosis could achieve the goal of improving walking function. Ankle-foot orthoses could not be confirmed to exert the role in the fol owing indicators, including time asymmetry, double support phase prolongation and stride length. This evidence shows that ankle-foot orthoses in hemiplegic patients may promote recovery of motor function of the lower limbs and activities of daily living to a certain extent, but the more high-quality, multi-center randomized control ed trials with large samples are necessary.

It is very necessary to apply case-teaching method to Emergency Medicine in Universities of TCM. To establish the case-teaching system,we ourselves have written teaching materials,trained teachers, and designed all sorts of the medical records. Moreover, we have deployed other methods and principles to put this teaching into practice, used clinical skill practising as a essential supplement of teaching effect. Comparing with the traditional teaching method, it is clear that case-teaching method could make students' learning initiative and positivity improved significantly, their test scores promoted obviously. Thus, carrying out case-teaching method in Emergency Medicine could advance students capability of acquisition of knowledge and their clinical thinking .

BACKGROUND: Spherical Toric intraocular lens can effectively correct the preoperative astigmatism of cataract patients, but it is unclear whether the aspheric Toric lens is better than the spherical Toric lens to improve the quality of vision. OBJECTIVE: To evaluate the optical quality after implantation of aspheric toric intraocular lens in cataract surgery. METHODS: Seventy-three cataract patients with corneal astigmatism (80 eyes) were enrol ed, including 37 males and 36 females, aged 47-83 years. Among them, 36 cases were implanted with aspheric Toric intraocular lens (test group), and the other 37 cases were implanted with spherical Toric intraocular lens (control group). Postoperative examinations were performed at 3 months, including axial intraocular lens, uncorrected visual acuity, corrected visual acuity, residual astigmatism, contrast sensitivity, and wavefront aberration. RESULTS AND CONCLUSION: Three months after implantation, the axial view, uncorrected visual acuity, corrected visual acuity and residual astigmatism showed no differences between the two groups; no shape deviation and lens decentration occurred; there was no case required to remove the lens or subjected to secondary adjustment. In the test group, the moderate and high spatial frequency contrast sensitivity at the scotopic or scotopic glare state was significantly higher than that in the control group (P < 0.05), the total higher order aberrations and spherical aberrations at a pupil diameter of 5.0 mm and spherical aberration at a pupil diameter of 3.0 mm were significantly less than those in the control group (P < 0.05). Additional y, there were no differences in scattering index, cut-off frequency of the modulation transfer function, Strehl ratio and visual acuity at 9%, 20% and 100% contrast between the two groups. These findings indicate that the aspheric and spherical toric intraocular lenses have similar effects in improving the astigmatism and raising the uncorrected visual acuity, but the former one is superior to the latter one in improving scotopic vision, and total higher order aberrations and spherical aberrations.

Objective To investigate the combined detection of serum vascular endothelial growth factor (VEGF),squamous cell carcinoma antigen (SCC-Ag)and cytokeratin 19 fragment (CYFRA21-1)value in assessing the efficacy of chemotherapy in patients with advanced squamous cell carcinoma of the lung.Methods 60 cases of lung squamous cell carcinoma patients in January 2011 between June 2013 to be admitted to hospital were treated with gemcitabine plus cisplatin or carboplatin chemotherapy.Detected the levels of serum VEGF,SCC-Ag and CYFRA21-1 expression in 60 cases before and after 1 cycle of chemotherapy in patients using ELISA and immunoradiometric assay,and evaluated the efficacy evaluation with reference to RECIST criteria after 2 cycle of chemotherapy.Results Effective group serum VEGF and CYFRA21-1 levels were 413± 114 pg/ml and 14.7±9.6 ng/ml;serum VEGF and CYFRA21-1 levels after one cycle of chemotherapy were 272±131 pg/ml and 10.8±7.1 ng/ml,which decreased after chemotherapy (P<0.01).Progress group serum VEGF and CYFRA21-1 levels were 472±207 pg/ml and 18.9±17.6 ng/ml;serum VEGF and CYFRA21-1 levels after one cycle of chemotherapy were 537±219 pg/ml and 21.5±20.2 ng/ml,which increased after chemotherapy (P<0.01).Stable group serum VEGF CYFRA21-1 levels and were 419±246 pg/ml and 17.0±12.9 ng/ml;serum VEGF and CYFRA21-1 levels after one cycle of chemotherapy were 421±252 pg/ml and 16.8±11.7 ng/ml,which had no changes before and after treatment (P>0.05). Serum SCC-Ag levels before and after each treatment group difference was not statistically significant (P>0.05).Multiple regression analysis showed that serum VEGF,CYFRA2 1-1 levels and the efficacy of lung squamous were related changed (t=5.86,P<0.001;t=2.26,P=0.027),and there was no significant correlation between SCC-Ag levels changes and the effect of chemotherapy (t=1.52,P=0.133).Conclusion Serum VEGF and CYFRA21-1 expression level changes associat-ed with squamous cell carcinoma of the lung chemotherapy effect,which can advance understanding of the effect of chemo-therapy,combined with advanced squamous cell carcinoma detection of serum VEGF and chemotherapy assessment CY-FRA2 1-1 has a certain reference value.

OBJECTIVE:To provide reference for promoting rational use of vancomycin in the clinic. METHODS:Referring to vancomycin instruction,Guiding Principles for Clinical Use of Antibacterials (2015 edition) and Chinese Expert Consensus on Clinical Use of Vancomycin (2011 edition),720 inpatient medical records of vancomycin were collected from our hospital during Jan. 2013-Dec. 2014,and then drug use of those inpatients were analyzed retrospectively. RESULTS:Among 720 cases,male (428 cases)was more than female(292 cases),and most of them aged 41-65(45.83%). There were 50 cases of prophylactic drug use(6.94%)and 670 cases of therapeutic drug use(93.06%). The patients came from 36 departments. Among 720 cases,the dose of 19 cases were higher than 2 g/d,and there were 13 ADR cases(1.81%). Among 670 cases of therapeutic drug use,587 cases of microbiological samples (87.61%) were detected,and other antibacterials were used in 522 cases additionally (77.91%). DUI of vancomycin was equal to 0.96 in 549 cases no younger than 18 years old of herapeutic drug use. There were 240 cases of unsuit-able drug use (33.33%) in total,including 192 cases of unsuitable solvent (26.67%),28 cases of unsuitable usage and dosage (3.89%)and 20 cases of unsuitable drug combination(2.78%). CONCLUSIONS:The use of vancomycin in our hospital is basi-cally rational;vancomycin is widely used in departments;drug combination is a common phenomenon;the inspection rate of mi-crobiological samples is qualified;no drug abuse is found. However,there still is inappropriate use in the clinic. It is recommended to strengthen special evaluation and training about rational use of vancomycin,and further standardize monitoring for vancomycin use so as to guarantee the safety of drug use.

Objective To investigate the reliability of the integrated method for kinetic assay of substrate in the presence of product inhibition using glutathione-S-transferase(GST) as model.Methods Purified GST from pig liver was used to catalyze the conjugation of reduced glutathione(GSH) to 1-chloro-2,4-dinitrobenzene(CDNB)(final concentration at 1.0mmol/L),and reaction curve was monitored by product absorbance at 340nm.Maximal product absorbance after the completion of reaction was predicted by the integrated method.Results The optimization of product inhibition constant conferred to resistance to the variation of residual substrate concentration on the estimation of maximal product absorbance.This integrated method for kinetic substrate assay was also resistant to common source of errors.The recovery for extra GSH in rat liver homogenate was above 98% with linear response ranged from 2.0?mol/L to 90 ?mol/L.The concentration of GSH in rat liver was consistent to previous reports.Conclusion The integrated method is valid for kinetic assay of substrate when there is product inhibition,and it exhibits some universality as a kinetic method for enzymatic analysis with obvious advantages.
