AIM：To examine the effects of patient age,canalicular obstruction,mode of anesthesia,and duration of nasolacrimal intubation on the outcomes of endoscopic endonasal dacryocystorhinostomy（DCR）. METHODS： Totally 56 eyes of 46 patients with prolonged epiphora underwent minimally invasive endoscopic endonasal DCR.A successful surgical outcome was defined as a significant improvement in symptoms,adequate water passage from the puncta to the nasal cavity,and patency of the DCR *** outcomes were assessed at least 6mo after ***＇s exact test was used to discuss the factors,and then the logistic regression analysis was made by SAS9.4 ***： The overall success rate was 75.0%,and complete resolution was observed in 27 *** success rate was higher for patients with ≥6mo intubation than for those with 〈6mo ***,there were no significant differences in outcomes between groups stratified by age（〈65 or ≥65y）,presence or absence of canalicular obstruction,mode of anesthesia（local or general）,and use or nonuse of a radiowave *** patient developed subcutaneous emphysema around the eye and nose and one developed subcutaneous hemorrhage after surgery. CONCLUSION： Endoscopic endonasal DCR can be considered safe and minimally invasive with reasonable success rates,particularly when the duration of nasolacrimal intubation is ≥6mo.

In 1956, Tong established an asymptotic formula for the mean square of the error term of the summatory function of the Piltz divisor function d3（n）. The aim of this paper is to generalize Tong＇s method to a class of Dirichlet series L（s） which satisfies a functional equation. Let a（n） be an arithmetical function related f t to a Dirichlet series L（s）, and let E（x） be the error term of ∑＇n≤x a（n）. In this paper, after introducing a class of Diriclet series with a general functional equation （which contains the well-known Selberg class）, we establish a Tong-type identity and a Tong-type truncated formula for the error term of the Riesz mean of the coefficients of this Dirichlet series L（s）. This kind of Tong-type truncated formula could be used to study the mean square of E（x） under a certain assumption. In other words, we reduce the mean square of E（x） to the problem of finding a suitable constant σ＊ which is related to the mean square estimate of L（s）. We shall represent some results of functions in the Selberg class of degrees 2 -4.

This study investigates the effects of addition of oxygen on the oxidative dehydrogenation （ODH） of methanol when a fluorotetrasilicic mica ion-exchanged with palladium （Pd2^＋-TSM） was used as the catalyst. The reaction proceeded at a very low temperature in the presence of oxygen, and HCOOCH3 was obtained at high selectivity. By calculating the equilibrium conversion, it has been shown that substantial ODH took place for HCOOCH3 production. Consequently, this reaction would make dehydrogenation the dominant reaction at equilibrium. Not all the H dissociated from CH3OH was converted to H20 by oxidation. It has been shown that the H2O was not produced from oxidative dehydrogenation by the direct reaction of CH3OH and O2 when an attempt was made to carry out oxidative dehydrogenation using an isotope oxygen trace method in the gas phase. Therefore, when CHaOH was converted to CO2 and dehydrogenated to HCOOCH3, the C-O bonds were not dissociated.

Advances in molecular diagnostic tools have allowed the identification of lymph node micrometastasis(LNM),including isolated tumor cells,in cancer patients. While immunohistochemistry and reverse transcription-polymerase chain reaction have been used to identify LNM in patients with gastric cancer,the clinical significance of this finding remains unclear. Recently,minimally invasive treatments,such as endoscopic submucosal dissection and laparoscopic surgery,are widely performed to help improve postsurgical quality of life(QOL). However,it is important to maintain the balance between QOL and curability when making treatments decision for patients with gastric cancer. If minimally invasive surgery based on accurate intraoperative LNM diagnosis was established,it could be performed safely. Therefore,we reviewed the clinical significance of LNM detected by molecular techniques as an important target for treatment decision making with gastric cancer patients.

In the present paper the attention is focused on the relation between vortex shedding phenomena and acoustic resonance which occurred in the two-dimensional model of boiler. There were tube banks with in-line arrangement for small tube pitch ratio. We measured the sound pressure level, the phase delay of acoustic pressures, the spectrum of velocity fluctuation and the gap velocity. As a result, we found two peak frequencies of sound pressure level with different Strouhal numbers St, mainly about 0.26 and 0,52, The noise of St=0.26 was the resonance of transverse mode and St=0.52 was longitudinal mode. The vortex shedding of St=0.15 was generated inside the tube banks without acoustic resonance. As gap velocity increased, we observed that the peak level of spectrum was weak and broad-banded, The onset velocity of the acoustic resonance of longitudinal mode was lower than that of transverse mode.
