AIM： To investigate the feasibility of treatment for upper gastrointestinal fistula and leakage with personal stage nutrition support. METHODS： Forty-three patients with upper gastrointestinal fistula and leakage were randomly divided into two groups. Patients in group A were treated with personal stage nutrition support and patients in group B were treated with total parental nutrition （TPN） in combination with operation. Nutritional states of the candidates were evaluated by detecting albumin （AIb） and pre-AIb. The balance between nutrition and hepatic function was evaluated by measurement of aspartate aminotransferase （AST）, alanine aminotransferase （ALT） and total bilirubin （Tbill） before and after operation. At the same time their complications and hospitalized time were surveyed. RESULTS： Personal stage nutrition support improved upper gastrointestinal fistula and leakage. The nutrition state and hepatic function were better in patients who received personal stage nutrition support than in those who did not receive TPN. There was no significant difference in the complication and hospitalized time in the two groups of patients. CONCLUSION： Upper gastrointestinal fistula and leakage can be treated with personal stage nutrition support which is more beneficial for the post-operation recovery and more economic than surgical operation.

AIM： To investigate factors associated with responses to intravitreal bevacizumab （IVB） in naive idiopathic choroidal neovascularization （iCNV） by high domain optical coherence tomography （OCT）. METHODS： We retrospectively reviewed clinical data of 40 eyes of iCNV patients who received a single or multiple IVB on an as-needed basis （1.25 mg/0.05 mL）. One month after the first injection, subretinal fluid （SRF） volume was evaluated and the eyes were divided into 3 groups based on responses to IVB. Good, moderate, and poor responses were defined as 61%-99%, 30%-60%, and 〈30% resolution of SRF on OCT after IVB in iCNV, respectively. OCT findings were analyzed to find factors associated with difference in response levels. Comparisons were made using Wilcoxon＇s matched- pairs signed-rank test, the Mann-Whitney U test for means with continuous data and Fisher＇s exact test for categorical data. RESULTS： The mean number of IVB was 1.28±1.50 and mean follow up time was 3.60±1.20mo. At postoperative 1too, there were 8 （20%） eyes in good response, 20 （50%） in moderate response and 12 （30%） eyes in poor response group and at last visit there were 28 good responders （70%）, 8 （20%） moderate responders and 4 （10%） poor responders. Statistically significant difference was detected between good responders and non good responders in choroidal neovessels thickness （P=0.029）, SRF height （P=0.049） and SRF volume （P=0.031） at post treatment 1 mo. CONCLUSION： OCT is a valuable diagnostic tool. Decrease in choroidal neovessels thickness, SRF height and volume predicts favorable response of iCNV to IVB therapy.

The Jaynes–Cummings model with or without rotating-wave approximation plays a major role to study the interaction between atom and light. We investigate the Jaynes–Cummings model beyond the rotating-wave approximation. Treating the counter-rotating terms as periodic drivings, we solve the model in the extended Floquet space. It is found that the full energy spectrum folded in the quasi-energy bands can be described by an effective Hamiltonian derived in the highfrequency regime. In contrast to the Z_(2) symmetry of the original model, the effective Hamiltonian bears an enlarged U(1)symmetry with a unique photon-dependent atom-light detuning and coupling strength. We further analyze the energy spectrum, eigenstate fidelity and mean photon number of the resultant polaritons, which are shown to be in accordance with the numerical simulations in the extended Floquet space up to an ultra-strong coupling regime and are not altered significantly for a finite atom-light detuning. Our results suggest that the effective model provides a good starting point to investigate the rich physics brought by counter-rotating terms in the frame of Floquet theory.

In order to investigate the structure-odor relationship of odoriferous compounds and search for new aroma chemicals, seven acetals of 4-trimethylsilyl-3-cyclohexenone and their carbon counterparts were synthesized by Birch reduction of 4-substituted anisoles and then acetalization. Seven acetals of 4-trimethylsilylcyclohexanone and their carbon counterparts were synthesized similarly. Structures of all new compounds were determined by MS, IR and ~1H NMR, and their characteristic odors were evaluated as well. The characteristic odors of the acetals formed by 4-substituted-3-cyclohexenone and 1, 2-diols are fruity and woody. The acetals formed from 1, 3-diols are woody, and formed with 1, 4-diols are very faint in odor. Odors of acetals of 4-substituted cyclohexanone are all very weak. As a whole, odors of organosilicon compounds are weaker, but somewhat more delicate than their carbon counter- parts.

The polarizations of dielectronic recombination satellite lines for hydrogenlike F to U ions are calculated including the generalized Breit interaction(GBI). The calculated values of the asymmetry parameter are compared with other theoretical results and good agreements are obtained for all lines except for those from the level 2s2p3P1. The GBI effects on the polarization become much stronger as the atomic number increases. However, for different lines, the GBI effects on the polarization are different.
