A graphically oriented interactive program for assignments of rotationally resolved molecular spectra has been devised. The program functions by grouping spectral lines in term of the second difference principle. and graphing spectral intensity versus frequency in a bar graph of the selected groups, distinguished by color and/or line-type. This allows for easy detection of regular patterns buried in the observed spectrum. Furthermore, it includes a Loomis-Wood view for assisting in spectral assignments. As an example, the program was applied in assigning the molecular spectrum of the production in the discharge of PCl3 buffered by helium gas, which may belong to several species. The results suggest that the program is highly efficient and quite useful in the assignment and the analysis of molecular spectra, especially those of symmetric top, slightly asymmetric top and linear molecules. The accuracy and efficiency of this program will likely ensure its wide application in the processing of molecular spectra.

Original article： Perichondrium/cartilage composite graft for repairing large tympanic membrane perforations and hearing improvement

A multifunctional inverse opal-like TiO electron transport layer(IOT-ETL) has been designed for efficient hybrid perovskite solar cells by a simple template-assistant method. Compared to the traditional TiO photoelectrodes consisting of both compact layer and mesoporous scaffold layer, the unitary inverse opal-like structure can not only enhance the light trapping ability but also prevent the recombination of carriers between the perovskite layers and FTO. The IOT-ETL based perovskite solar cell shows a high power conversion efficiency(PCE) of 13.11 %. Light-harvesting efficiency(LHE) measurement demonstrates that the porous structure could enhance light trapping ability of IOT-ETL film, which improves the generation of photo-excited electrons and further enlarges the short-circuit current density(Jsc). The room temperature photoluminescence(PL) spectrum and dark current density(J) – voltage(V) characteristics illustrate the necessity of the bottom in IOT-ETL film, which could restrict the charge recombination and improve open-circuit potential(V). Such unique morphological advantages and simple fabrication process make the IOT-ETL a promising electrode candidate for high-performance and low-cost perovskite solar cells. Moreover, it will pave the way for light management by introducing photonics structure in perovskite solar cells.

Background The main risk factors for postoperative failure in tympanoplasties are large perforations that are difficult to repair, annular perforations, and a tympanic membrane （TM） with extensive granular myringitis that require middle ear exploration and mastoidectomy. The aim of this study was to investigate a novel technique of perichondrium/cartilage composite graft for repairing the large TM perforation in the patient of otitis media. Methods Retrospective chart reviews were conducted for 102 patients with large tympanic membrane perforations, who had undergone tympanoplasty from August 2005 to August 2008. Tympanoplasty or tympanomastoidectomy using a perichondrium/cartilage composite graft was analyzed. The tragal or conchal perichondrium/cartilage was used to replace the tympanic membrane in patients. Results Patients aged from 13 to 67 years were followed up in average for 24 months （10-36 months）. Seventy-four ears （72.61%） were used the tragal perichondrium/cartilage as graft material and 27 ears （27.39%） were used the conchal perichondrium/cartilage. Graft take was successful in all patients. Postoperative complications such as wound infection, hematoma, or sensorineural hearing loss were not identified. Nine patients （8.82%） had the partial ossicular replacement prosthesis, 14 patients （13.72%） using the autologous curved incus and 79 patients （77.45%） without prosthesis. Successful closure occurred in 92% of the ears. A total of 85.8% patients achieved a postoperative hearing improvement. Conclusions The graft underlay tympanoplasty using perichondrium/cartilage composite is effective for the majority of patients with large perforation. The hearing was improved even if the mastoidectomy was required in the patients with otitis media with extensive granulation.

Background Off-pump coronary artery bypass surgery （OPCAB） has been widely applied in recent years as a less invasive method of myocardial revascularization. This study evaluated the sequential bilateral internal mammary artery grafting combined with selective arterialization of the coronary venous system during *** From April 2004 to August 2010, patients with diffuse right coronary lesions were studied retrospectively and divided into two groups. Group 1 included seventeen patients who underwent this surgery while group 2 included twenty-one patients without right coronary artery surgical therapy. All patients presented with symptoms of angina. Blood flow of bridged vessels was measured. The perioperative ventricular parameters including left ventricular ejection fraction and end diastolic diameter were compared. During follow-up, myocardial nuclide imaging and coronary angiography were carried *** Off-pump coronary artery bypass was performed with an average of 3.6 grafts per patient. Hospital mortality was zero. At the time of follow-up, the patients in group 1 recovered better than in group 2 （P〈0.05）. In both groups, the mean New York Heart Association （NYHA） class and ejection fraction increased significantly （P〈0.001） and the mean left ventricular end-diastolic diameter decreased significantly （P 〈0.05）. Myocardial blood supply of inferior wall in group 1 was obviously improved by myocardial nuclide imaging. Coronary angiography for eight patients in group 1 verified that there was blood flow to myocardium in the arterialized *** Sequential bilateral internal mammary artery grafting combined with selective arterialization of the coronary venous system can be performed during OPCAB. A postoperative improvement in the cardiac functions and the quality of life was documented, increasing our expectation for extensive application.
