AIM： To describe the clinical features of congenital double elevator palsy（CDEP） and to evaluate various surgical outcomes between the standard Knapp and augmented Knapp procedures, based on improvements in primary eye position and ocular ***： Twenty-two patients with CDEP at Shanghai Children＇s Hospital were enrolled from July 2014 to January 2018. The forced duction test（FDT） was negative in 21 patients, aged 8 mo to 12 y（mean 5.4 y）. Patients were divided into two treatment groups： 16 patients underwent the standard Knapp procedure（group A）, with or without horizontal squint procedure; and 5 patients underwent the augmented Knapp procedure（Foster procedure; group B）. One patient underwent inferior rectus recession in the affected eye and superior rectus recession in the sound eye because of a positive FDT. The pre-and postoperative vertical deviations in the primary position and ocular motility were compared in the two ***： Twenty-one eyes of the 22 patients（95%） were aligned within 10 prism diopters（PD）, and all patients（100%） reached ≥25% elevation improvement after surgery. The average corrected vertical deviation in group B was statistically better than that of group A. For group A, the vertical deviation in the primary position decreased from 24.75Δ±8.35Δ to 4.56Δ±8.07Δ after surgery, for an improvement of 23.06Δ±6.51Δ（P〈0.05）. In group B, the decrease was from 35.00Δ±5.00Δ（range 30Δ-40Δ） to 1.00Δ±2.24Δ, for an improvement of 34.00Δ±4.18Δ（P〈0.05）. There were significant differences between the pre-and postoperative elevation in each group（group A, P〈0.05; group B, P〈0.05）. The average scale of improved elevation in group B（1.80±0.45） was not significantly better than that of group A（1.69±0.87; Z=-0.732, P=0.548）. The average follow-up periods lasted 21 mo in group A and 18 mo in group ***： For vertical deviations 〈30Δ, the standard Knapp procedure can be chosen. For deviations greater than 30Δ-40Δ, the Foster procedure should

A new model on predicting the density of hot-rolled multi-phased medium-Mn steel has been presen ted on the basis of thermodynamic calculations. This is an integrated model, which includes one for calculating the retained austenite （RA） fraction and the other for volume expansion during the aus tenite-to martensite transformation, because both of them are key parameters for calculating the den- sity of steel at ambient temperature. The existing empirical equations for calculating Mx temperature and lattice constants of both martensite and austenite have been all rcassessed by the XRD measure ments on the microstructures of seven hot-rolled medium-Mn steels. Finally, the densities ot seven steels were calculated merely from compositions and compared with the measured ones. The differ ence between them is no more than 1 %, suggesting that the presented model should be of good value in designing the low density steels.

We report a^19F nuclear magnetic resonance(NMR)study on single-crystal KCa2 Fe4As4F2(Tc^33.3 K).The 19F NMR spectral shape of KCa2Fe4As4F2 is weakly dependent on temperature and the Knight shift is small,which implies weak coupling between the Ca F layer and the Fe As *** temperature dependence of 1/^19T1 shows a hump below Tc,however the 1/^75T1 decreases just below Tc,which implies that there are strong in-plane magnetic fluctuations in the Ca F layers than in the Fe As *** may be caused by the motion of *** absence of the coherence peak suggests unconventional superconductivity in KCa2Fe4As4F2.

The incidence of multiple primary cancers involving trachea is rare. We present a case of synchronous double primary cancer of trachea and esophagus in a 70-year-old woman, with a special symptom of ventricular tachycardia and no/a/story of smoking and alcohol drinking. Biopsies （tom multiple loci demonstrated the patient had primary small cell cancer of trachea and squamous cell carcinoma in situ of esophagus. The patient was successfully treated with four cycles of chemotherapy consisting of etoposide and earboplatin （EC） followed by thoracic radiotherapy （60 Gy in 30 fractions, in 6 weeks）, and was evaluated to have complete response of tumor. To our knowledge, there is no synchronous cancer of trachea and esophagus has been reported in English literature, and our experience showed sequential EC chemotherapy and radiotherapy provided an effective treatment to control both cancers.
