ABSTRACT

Objective: To investigate the clinicopathological characteristics of testicular biopsies from Klinefelter syndrome (KS) patients. Methods: The testicular biopsy specimens of 87 patients with KS (a total of 107 biopsy specimens) were collected from the Department of Pathology, Peking University Third Hospital, Beijing, China from January 2017 to July 2022. All patients were diagnosed as KS by peripheral blood karyotyping analysis. The testicular histopathologic features, testicular volume and hormone levels were evaluated retrospectively. The histopathologic analysis was used to assess the quantity and morphology of Leydig cells, the spermatogenic state of seminiferous tubules, the thickening of the basement membrane of seminiferous tubules and the changes of stroma. Results: Leydig cell proliferative nodules were seen in 95.3% (102/107) of KS testicular biopsy tissues. The eosinophilic inclusion bodies and lipofuscin in Leydig cells were found in 52.3% (56/107) and 57.9% (62/107) of specimens, respectively. The Sertoli cell only seminiferous tubules and the hyalinized tubules were found in 66.4% (71/107) and 76.6% (82/107) of the examined tissues, respectively. The tubules with complete spermatogenic arrest were found in 15.9% (17/107) of specimens, and 5.6% (6/107) of the specimens showed low spermatogenesis or incomplete spermatogenic arrest. In 85.0% (91/107) of the specimens, increased thick-walled small vessels with hyaline degeneration were identified. Conclusions: The most common features of KS testicular specimens are Leydig cell proliferative nodules, hyaline degeneration of seminiferous tubules and proliferation of thick-walled blood vessels. Testicular biopsy specimens of KS are rare. The pathologists can make a tentative diagnosis of KS based on the histological findings, combined with the ultrasound and laboratory results, which is helpful for further diagnosis and treatment of KS.

ABSTRACT

In order to clarify the chemical constituents in Qiliqiangxin capsule, a rapid ultra-performance liquid chromatography/orthogonal acceleration time-of-flight mass spectrometry (UPLC-Q-TOF/MS(E)) method was established. Forty peaks were identified on line using this method. The herbal sources of these peaks were assigned. The results implied that triterpenoid saponins, flavonoid glycosides, C21-steroids and phenolic acids were included in the main components of Qiliqiangxin capsule. The method is simple and rapid for elucidation of the constituents of Qiliqiangxin capsule and the results are useful for the quality control of Qiliqiangxin capsule.

ABSTRACT

<p><b>OBJECTIVE</b>To observe the clinical efficacy of shensong yangxin capsule (SYC) on ventricular premature beat (VPB) differentiated in TCM as palpitation of Qi-yin deficiency syndrome or Xin collateral stagnation syndrome, and cardiovascular autonomic nervous function in patients with coronary heart disease (CHD).</p><p><b>METHODS</b>The randomized, double-blind, parallel contrast method was adopted, patients were randomly assigned by 3:1 ratio into two groups. One hundred and sixty-five patients in SYC treated group and 56 in the control group (treated with Xinlvning tablet), and the therapeutic course for both groups was 4 weeks.</p><p><b>RESULTS</b>The clinical efficacy on VPB and in improving TCM syndromes was better in SYC group than that in the control group (P < 0.01). After treatment, the heart rate variability (HRV) and QT dispersion in the two groups were improved in a certain degree. The changes of SDNN, SDANN, SDNN Index and PNN50 in the two groups were significantly different (P < 0.05, P < 0.01), the efficacy in the treated group was superior to that in the control group.</p><p><b>CONCLUSION</b>SYC has definite effect on VPB and TCM Syndromes, it can obviously meliorate the activity of cardiovascular autonomic nervous system in the patients with CHD.</p>
