Objective To investigate the variety and clinical value of the neutrophil volume and cytoplasm-nucleus complex in patients with bacterial infection, cardiovascular or cerebrovascular accident and major surgery operation. Methods 125 patients with bacterial infection, 64 patients with acute cardiovascular or cerebrovascular accident, 66 patients after major surgery operation and 69 normal subjects were selected in the study. Total WBC counts (WBC), percentage of neutrophils (NE), and the VCS parameters of neutrephils including the mean channels of cell volume ( NEV), conductivity ( NEC), light scatter(NES) and the SD of these parameters( NEVSD, NECSD, NESSD)were measured by automatic blood cell analyzing instrument. The sensitivity and specificity of the WBC, NE and the VCS parameters of neutrophils were analyzed with receive operating characteristic (ROC) curve. Results The levels of NEV, NES and NEVSD in acute bacterial infection group were 154.3 ± 15.2, 135.7 ± 9.9, 26.8 ± 4.2 respectively. The levels of NEV, NES and NEVSD in post major surgery operation group were 147.2±8.9, 141.5 ± 7.7, 23.0 ± 2. 8 respectively. The levels of NEV, NES and NEVSD in acute cardiovascular or cerebruvascular accident group were 144.9 ± 5. 2, 146.0 ±5.0, 19. 6±1.6 respectively. The levels of NEV, NES and NEVSD in healthy control group were 139.7±4.6, 145.0±3.8, 18.2±1.3 respectively. The differences of these parameters among these groups had statistical significance ( F = 17. 650, 38. 122, 54. 604,P<0. 05). And the changes of NEV, NES and NEVSD in bacterial infection group were most obvious among those three groups. The levels of NEV, NES and NEVSD were 146.5±9.5, 144.3 ± 9.4, 21.3 ± 3.3 respectively in stress diseases groups which included acute cardiovascular or cerebrovascular accident group and post major surgery operation group. The differences of these parameters between stress diseases group and acute bacterial infection group had statistical significance ( t = - 2.840, 7.533, - 8.999,P<0.01). The areas under the ROC curve of NEVSD, NEC, NES and NECSD were 0.893, 0. 845, 0. 833 and 0. 849 respectively. The sensitivity of 83. 3% and specificity of 82. 0% could be achieved by selecting the cut-off equal to or greater than 24. 0. Conclusions The variety of neutrophil volume, nuclear size and cytoplasmic granularity changed obviously in patients with acute bacterial infection and common stress diseases, and the variety in acute bacterial infection is more obvious than that in common stress diseases. The sensitivity and specificity of VCS parameters of neutrophils are higher than those of WBC or NE for predicting infection, and the NEVSD is the most predictable indicator of acute bacterial infection.

The “conception vessel， governor vessel and thorough vessel sharing the same origin” theory refers to the concept that the conception vessel， governor vessel and thorough vessel all originate from the same source within the uterus and emerge from the perineum. Based on the modern research of McNeal's prostate zonal anatomy theory， it is believed that the conception vessel， governor vessel and thorough vessel have the closest relationship with the prostate in terms of their origin and running course. It is proposed that the essential meaning of the ‘conception vessel， governor vessel and thorough vessel sharing the same origin’ theory in relation to the prostate is that the conception vessel， governor vessel and thorough vessel respectively connect to the transition zone， peripheral zone， and central zone of the prostate. Moreover， the differences in the yin-yang attributes of the conception vessel， governor vessel and thorough vessel exhibit distinct functional characteristics in different zones of the prostate， which serve as an important basis for the physiological and pathological differences in various prostate zones. Based on this premise， a prostate meridian， qi and blood syndrome differentiation method is further proposed， wherein the differences in the meridian characteristics of the conception vessel， governor vessel and thorough vessel determine the differences in the yin-yang aspects of qi and blood in different prostate zones. When clinical diagnosis is conducted， the inherent physiological differences of the different prostate zones should be fully taken into account， as well as the pathological characteristics of the disease， in order to guide the diagnosis and treatment of related clinical conditions.

ObjectiveTo analyze the characteristics of tradition Chinese medicine (TCM) syndromes in patients with urolithiasis. MethodA syndrome questionnaire was developed to collect the general data and four diagnosis information on 296 patients with urolithiasis who were treated from September 2021 to September 2022. Tongue images, pulse images, symptoms, and signs were statistically analyzed, and the characteristics of syndrome were explored by association rule analysis, factor analysis, and cluster analysis. Result① In the distribution of tongue images, the single tongue images with a frequency of more than 20% were white fur, red tongue, thick fur, greasy fur, and yellow fur. In the distribution pf pulse images, the single pulse with the frequency of more than 20% was fine pulse, string pulse, slippery pulse, and sinking pulse. There were 27 symptoms and signs with a frequency of more than 10%. The characteristic symptoms of acute onset such as lumbar and abdominal pain and nausea, frequent urination, hematuria, and poor urination were relatively common, and other symptoms were chill and fever, defecation, and digestion. ② Among the 14 strong association rules, 5 were yang-deficiency and cold-dampness syndromes, 4 were yin-deficiency and heat syndromes, 1 was kidney-deficiency syndrome, and 3 were renal colic with accompanying symptoms. ③ Sixteen common factors were extracted by factor analysis, and the main elements of the disease location were represented by spleen and kidney. The main elements of disease natures were Yin deficiency, Yang deficiency, dampness, and heat, and often mixed with deficiency-excess in complexity. Six syndromes were obtained by cluster analysis, and the represented syndromes were mainly kidney deficiency and dampness and stasis, Qi stagnation and heat accumulation, Yin deficiency and dampness heat, spleen-kidney Yang deficiency, spleen deficiency and dampness, and dampness-heat accumulation. ConclusionThe syndrome manifestations of urolithiasis are chill and fever, defecation, sweating, and digestive tract symptoms. The deficiency syndromes are mainly Yin deficiency, Yang deficiency, kidney deficiency, and spleen deficiency. The excess syndromes are mainly wet and heat. The deficiency and excess syndromes often exist simultaneously. The spleen deficiency is the important pathogenesis of urolithiasis besides the kidney deficiency.

Objective:To quantify the fat of extraocular muscle in TAO patients with MRI fat-water separation technique.Methods:66 patients (129 eyes) with TAO were included in this study from November 2017 to July 2019. The age, gender, course of disease, disease activity and severity were collected. Fat fraction(FF) of the heaviest inflamed extraocular muscle was used as FFmax, the average FF of each orbital was recorded as FFmean. FF differences between groups of severity and activity were compared, the correlation between FF and clinical characteristics was also analyzed. Meanwhile, the changes of FF in follow-up patients before and after treatment were compared.Results:FFmean and FFmax of mild group were higher than moderate-to-severe as well as sight-threatening group. In male patients, active group′s FFmean and FFmax were lower. FF was different in groups which based on disease course ( P<0.05). Spearman correlation analysis showed a positive correlation between FF and disease course. Besides, there was a negative correlation between FF, disease activity, and disease severity ( P < 0.05). FF increased after treatment(FFmean: 34.03%±6.75% vs 32.26%±6.06%, P=0.040; FFmax: 33.43%±9.44% vs 29.04%±8.45%, P=0.006). Conclusion:MRI fat fraction can quickly and objectively quantify the fat of extraocular muscle, providing a new reference index for TAO′s disease evaluation.
