目的分析多排螺旋CT在腰部肌群形态学参数与临床症状严重程度的关系。方法选取本院2015年1月~2023年12月收治的60例下腰痛症状患者,所有患者均接受多排螺旋CT扫描,于患者L3椎体最长横突水平测定腰大肌、腰方肌、竖脊肌的横断面积以及CT值;观察组患者接受日本骨科协会评估治疗指数(JOA)评估,其中患者依据JOA评分分为轻度组、中度组和重度组。比较不同临床症状严重程度的患者一般资料及腰部肌群形态学参数。结果依据JOA评分,评分在17~23分之间27患者纳入为轻度组,评分在8~17分的20例患者纳入为中度组,评分≤8分的13例患者纳入为重度组。不同临床症状严重程度患者临床资料比较差异无统计学意义(P>0.05),但不同临床症状严重程度患者腰大肌、腰方肌、竖脊肌的横断面积及CT值均存在差异(P>0.05);Spearman相关性分析显示,腰大肌、腰方肌、竖脊肌的横断面积、CT值与临床症状严重程度呈显著负相关(P<0.05);经多因素Logistic回归分析结果显示,腰大肌、腰方肌、竖脊肌的横断面积、CT值为临床症状严重程度的影响因素(P<0.05)。结论多排螺旋CT下的腰部肌群形态学参数与腰痛患者症状严重程度存在明显相关性。

We present a room temperature nonlinear mass sensing based on a hybrid spin-nanoresonator system with the microwave pump–probe technique and the spin readout technique, which includes a single spin of nitrogen–vacancy (NV) center in diamond and a nanomechanical cantilever. The resonance frequency of the nanoresonator can be measured with the nolinear Kerr spectrum, and the parameters that influence the nolinear Kerr spectrum are also investigated. Further, according to the relationship between frequency shifts and variable mass attached on the nanoresonator, this system can also be used to detect the mass of DNA molecules with the nolinear Kerr spectrum. Benefiting from the single spin of the NV center in diamond has a long coherence time at 300 K, the hybrid system can realize room temperature mass sensor, and the mass response rate can reach 2600 zg/Hz.

The hydrogen-bonded interaction between acylamine and chloromethane was studied using theoretical calculation methods. Looking the interaction system as a hydrogen-bonded complex, the geometric optimization of the interaction system was performed with HF and B3LYP methods at 6-311＋＋G^＊＊ level. Stable structures of these complexes were obtained. Binding energies and some other physical chemistry parameters of them were computed and compared. According to the calculation results, it can be identified that DMA （DMF or DEF） can form stable complex with chloromethane by the hydrogen-bonded interaction between them. The stable orders of these hydrogen-bonded complexes were obtained and described as： DMF-CHCl3〉DMF-CH2Cl2〉 DMF-CH3Cl, DEF-CHCl3 〉 DEF-CH2Cl2 〉 DEF-CH3Cl, DMA-CHCl3 〉 DMA-CH2Cl2 〉 DMA-CH3Cl, respectively.

1 Introduction Traditional Chinese medicine (TCM) is "the traditional medicine that originated in China,and is characterized by holism and treatment based on pattern identification/syndrome differentiation" (WHO,2007).In China,traditional medicine accounts for around 40％ of all healthcare delivered;in the West,TCM is increasingly adopted by medical practitioners as a form of complementary and altemative medicine (CAM) (WHO,2002).Both in China and in the West,scientists are attempting to bring the ancient heritage of TCM into line with modem standards,through the scientific development of TCM in the direction of evidence-based medicine (Qiu,2007).There is a pressing need for the digital preservation and global access of TCM knowledge assets.

The effects of waves on Surface Drag Coefficient （SDC） and surface mixing length were analyzed and discussed by carrying out three-dimensional current modeling for the Bohai Sea in the present work. A threedimensional coupled hydrodynamical-ecological model for regional and shelf seas （COHERENS） incorporating the influences of wave-current interactions was coupled with the third-generation wave model swan taking into account time-varying currents. The effects of waves on currents were included in the SDC, surface mixing length and bottom drag coefficient. Firstly, the formulations in Donelan were incorporated into the COHERENS to account for wave-dependent SDC. In order to compare simulation results for the wave-dependent SDC, the simulation for wind-dependent SDC was also carried out. Second, Wave-Induced Surface Mixing Length （described as WISML sometimes in this paper） was incorporated into the COHERENS. Four numerical experiments were conducted to discuss the effects of two kinds of wave processes. Generally, the values of time series of current velocity and water surface elevation given by the simulation with all of the three wave processes have a good agreement with observed data. The existence of WISML changes obviously current vertical profiles and the existence of the wave dependent SDC modifies the current field of both top and bottom layers with the wind-dependent SDC.
