The purpose of this paper is to provide parameters of physiological functions in elite athletes of track andfield, swimming, volleyball and gymnasts with reference to criteria for recruitment. Tests were made on 811males and 761 females for 14 physiological indices, including pulse rate, blood pressure and step test. Significant correlations were found between the performance level of track and field and swimming on theone hand and the athletes' vital capacity and Vo_2max on the other. Players of the national women volleyballteam were found to be more responsive in nervous reflexes and possess a lower percentage of body fat and agreater lean body weight than their counterparts on other teams. The gymnasts were found to be inferior incardiopulmonary function, which might be one of their pnysiological characteristics. In most items the subjects'parameters were mean?one SD. It is believed that for better performances an athelet must improve his cardio-pulmonary function.

0.05). Conclusions The expression of XAF1 decreases in both malignant and benign colo-rectal tumors and is significantly lower in colorectal carcinomas than in adenomas/polyps. Thus, XAF1 may have the potential role in differentiating colorectal cancer from benign tumors.

Aim To investigate the behavioral changes of the pain related neuromodulation and neurotransmission in peripheral and central nervous systems in rats with trigeminal neuralgia (TN)and provide a disease relevant animal model for mecha-nism study of TN.Methods The male SD rats were randomly divided into sham operation group and TN surgical group.The latter group was further divided into model group and gabapentin group (100 mg · kg-1 ). TN was induced by intravenous erythrosine B injection and laser irradiation.The pain behavior of rats was evaluated using mechanical pain threshold measured with Von Frey hairs.Fluorescence quantitative PCR technique was deployed to study the change of Tac1 mRNA expressions in trigeminal ganglia.Utilizing microdialysis technique followed by high performance liquid chromatography fluorescence detection (HPLC-FLD),the extracellular striatum fluid was collected and glutamate(Glu)concentration was determined.Results In the model group,the average mechanical pain threshold in facial ar-ea innervated by the trigeminal nerve remained below 4g after 7 days post surgery.The mechanical threshold of the model group (1.63 ±1.27)g was significantly lower (P<0.01)than the control group (24.17 ±4.49)g on day10 post surgery.In gen-eral,the mechanical withdraw threshold was decreased from the preoperative value of 26g to the postoperative value of (1.60 ± 1.74)g (P<0.01),and maintained stable at (0.71 ±1.24) g during the whole dynamic monitoring period from day7 to day60.The successful rate of this model was 63%.After sur-gery,Tac1 mRNA expression in trigeminal ganglia and extracel-lular Glu levels in striatum were significantly up-regulated (P<0.05 ) in the model group. Animals receiving Gabapentin showed significant improvement in pain symptoms,as well as re-ductions of Tac1 mRNA expression in trigeminal ganglia and ex-tracellular Glu concentration in striatum (P<0.05 ).Conclu-sions The above described photochemically induced TN rat model can partially mimic the clinical TN symptoms and its pathophysiology.Considering its overall high stability,it is very likely that this model could be used in preclinical mechanism study or drug screening of TN.

Objective To investigate the clinical efficacy of Kirschner wire,reconstruction plate and locking compression plate internal fixation in the treatment of Robinson type 2A and 2B midshaft clavicle fracture.Methods One hundred and fifty patients with midshaft clavicle fracture in the hospital from August 2006 to August 2015 were selected and divided into the group A,B and C.The group A adopted Kirschner wire,group B adopted the reconstruction plate and group C adopted the locking compression plate internal fixation.Then the incision length,operative time,intraoperative blood loss,fracture healing time,postoperative Constant-Murley scores and DASH scores and postoperative complications incidence rate were compared among the three groups.Results The incision length,operative time and intraoperative blood loss in the group A and C were significantly better than those in the group B(P＜0.05).The fracture healing time,postoperative activity,muscle strength and daily life score,postoperative complications incidence rate,postoperative DASH score in the group C were significantly better than those in the group A and B(P＜0.05).Conclusion The locking compression plate in the treatment of Robinson type 2A and 2B midshaft clavicle fracture can effectively reduce the surgical trauma,shortens the fracture healing time and decreases the postoperative complications.

Objective:To evaluate the reliability of cardiac late iodine enhancement dual-energy CT (LIE-DECT) multiparameter post-processing technique for evaluating the presence, location, and extent of cardiac scars in patients with heart failure (HF), using cardiac MR (CMR) late gadolinium enhancement (LGE) as a reference standard.Methods:Thirty-nine HF patients who underwent cardiac LIE-DECT and LGE-CMR examinations in the Second Affiliated Hospital of Nantong University from November 2019 to November 2021 were prospectively collected, all enrolled HF patients underwent LIE-DECT post-processing to reconstruct monoenergetic plus (Mono+) map (40 keV), iodine map and Rho/Z map, to evaluate the enhancement degree, location and extent of left ventricular myocardial LIE on the left ventricular short-axis map, respectively, and compared with LGE-CMR. Cohen′s Kappa test was used to assess the intra-and inter-observer consistency of LIE by DECT multiparameter technique and the consistency of LIE presence and location by DECT multiparameter technique and by CMR. The diagnostic efficacy of DECT multiparameter technique in diagnosing myocardial scar was calculated.Results:Of the 39 patients included, 32 patients were detected by CMR with LGE in 147 segments, including 37 subendocardial patterns, 19 transmural patterns, 74 mid-wall patterns, and 17 epicardial patterns. The intra-observer consistency Kappa values of 40 keV Mono+map, iodine map and Rho/Z map were 0.878, 0.930 and 0.835 ( P all<0.001), respectively. The inter-observer consistency Kappa values were 0.838, 0.892 and 0.808 ( P all<0.001), respectively. The LIE of 40 keV Mono+map, iodine map and Rho/Z map were in good agreement with CMR, Kappa values were 0.903, 0.883 and 0.810 ( P all<0.001), respectively. For the per-patient analysis, the accuracies of 40 keV Mono+map, iodine map and Rho/Z map were 92.3% (36/39), 92.3% (36/39) and 82.1% (32/39), respectively. For the segment-based analysis, the accuracies of 40 keV Mono+map, iodine map and Rho/Z map accuracy were 96.1% (492/512), 95.3% (488/512) and 92.6% (474/512), respectively. In Bland-Altman analysis, the consistency bias between scar extent measured by 40 keV Mono+map, iodine map, Rho/Z map and that measured by LGE-CMR were -2.03%, -2.21%, -2.65%, and the 95% limit of agreement were -12.20%-8.14%, -12.69%-8.28% and -14.85%-9.58%, respectively. Conclusion:LIE-DECT multiparameter technique can detect myocardial scar in HF patients well, which is consistent with LGE-CMR.

With the continuous development of traditional Chinese medicine （TCM）， the requirement for the quality of Chinese medicines has become increasingly higher since they have been widely used in clinical practice. Chinese medicinal materials are the material basis for the inheritance and development of TCM， and their quality directly affects the clinical efficacy. Studying the quality of Chinese medicinal materials is the key to ensure the quality and realize the large-scale application. As one of rare Chinese medicinal materials， Cistanches Herba has the functions of tonifying kidney yang， invigorating blood and essence， moistening intestines to relieve constipation. High-quality Cistanches Herba is characterized by glossy appearance， high density， fleshy and soft texture， and sweet taste. With the reduction of wild resources， the products from cultivated Cistanche deserticola or C. tubulosa become dominant on the market of Cistanches Herba. The cultivation areas are widely distributed， mainly concentrated in Gansu， Inner Mongolia， and Xinjiang. However， the cultivated products have varied quality due to the differences in germplasm， producing region， cultivation method， harvesting， and processing. According to the theories of quality evaluation based on morphological characteristics and excellent appearance indicating high quality， this paper reviewed the literature on the quality evaluation， growth， development， and processing of Cistanches Herba in the last decade to explore the main factors （genetic characteristics， environmental conditions， and harvesting and processing factors） affecting the quality of Cistanches Herba. The review aims to explore the factors for the high quality and provide a reference for the producing region screening， directional cultivation， and production of Cistanches Herba.

Colorectal cancer (CRC) is highly heterogeneous, but traditional TNM staging cannot distinguish the heterogeneity of CRC well, which can no longer meet the treatment needs. Integrating the clinical features, molecular genetic changes in cancer tissue, transcriptome and proteome changes, as well as immune matrix characteristics, the consensus molecular subtype (CMS) of CRC is by far the best description of its heterogeneity. This paper first discusses the molecular genetic changes of three types of CRC cancer tissues (chromosomal instability, microsatellite instability, and CpG island methylation phenotype). Then it systematically elaborates on the clinical characteristics, treatment directions, and prognosis evaluation of CRC patients with different CMS subtypes, as well as their relationship with immunotherapy and changes in gut microbiota. With the continuous improvement of sequencing technology and the prospective precision medicine clinical trial exploration, the "multi-molecule — multi-drug" treatment model based on CMS typing will become the core of future precision medicine and personalized medicine.

Recent advancement in natural language processing (NLP) and medical imaging empowers the wide applicability of deep learning models. These developments have increased not only data understanding, but also knowledge of state-of-the-art architectures and their real-world potentials. Medical imaging researchers have recognized the limitations of only targeting images, as well as the importance of integrating multimodal inputs into medical image analysis. The lack of comprehensive surveys of the current literature, however, impedes the progress of this domain. Existing research perspectives, as well as the architectures, tasks, datasets, and performance measures examined in the present literature, are reviewed in this work, and we also provide a brief description of possible future directions in the field, aiming to provide researchers and healthcare professionals with a detailed summary of existing academic research and to provide rational insights to facilitate future research.
