Objective: To observe the effect of Juebi capsule (JBC) on experimental prostatic hyperplasia. Methods: Experimental prostatic hyperplasia was induced by castration testicular nourmone in the mice and rats respectively and the isolated bladder trigone muscle of the rabbit was used for contraction inhibition. Results: For mice, JBC 10 20g/kg was administered intragastrically for 10 days; for rats, JBC 1 2g/kg was taken for 3 weeks. The results showed that JBC can significantly inhibite prostatic hyperplasia and decrease wet weight of the gland, DNA content and the activity of serum acid phosphatase. Otherwise, 0.25%, 0.50% and 0.75% water suspension of JBC also can inhibite the contraction induced by norepinephrine in isolated bladder trigone muscle of the rabbit. The inhibition rates were 29.17%, 41.72% and 62.29%.Conclusion: JBC can significantly inhibit experimental prostatic hyperplasia and decrease contraction of bladder trigone muscle induced by ? adrenoceptor agonist.

Objective To clone and express the human asialoglycoprotein receptor(ASGPR) H1 subunit, purify and identify the immunoreactivity of the recombinant protein, and establish the enzyme linked immunosorbent assay (ELISA) to detect anti-ASGPR antibodies in diagnosis of autoimmune hepatitis. Methods The CRDHI cDNA (435 bp) was subcloned into eukaryotic vector PEGH, and the recombinant protein expression was induced by D (+)-Galactose. The recombinant CRDH1 was purified with Glutathione Sepharose 4B, and its immunoreactivity was identified by SDS-PAGE and western blot as well as MALDI-TOF. ELISA was established to detect the anti-ASGPR antibodies in serum samples of 45 patients with AIH, 30 patients with SLE, 30 patients with RA, 10 patients with SS and 30 normal controls. Results The sequencing of recombinant plasmid showed the CRDH1 gene was successfully inserted to the eukaryotic expression vector with correct sequence and open reading frame. The fusion protein showed a molecular weight of 42 500 Da on SDS-PAGE gel and confirmed to be the human ASGPR by MALDI-MS through peptide mass fingerprint analysis with Mascot in human protein database. It shared 98. 34% homology with ASGPR H1 subunit. Western blot analysis showed that the fusion protein had the same immunoreactivity as human ASGPR. The results of ELISA indicated that the positive rate of anti-ASGPR was 35.6% ( 16/45 ), but the ELISA was negative in other control. There was significant difference of positivity of the autoantibodies between AIH and non-AIH controls (χ2 = 31.85,P < 0. 01 ). Conclusions The human plasmid containing ASGPR is successfully clone into Saccharomyces cerevisiae Y258. The recombinant autoantigen owns good antigenicity and specificity. ELISA established with the purified protein shows good specificity for diagnosis of AIH.

To clarify the effect of the sympathetic nerves on the body's physiopathological changes and acupuncture effect by the alphal-AR mediation in the past 30 years.The paper has referred to the database of CNKI and Pubmed,and systematically reviewed the publications in the past 30 years about the research of the alphal-AR mediation of the sympathetic nerves to the body's physiological andpathological changes and acupuncture effect.Alphal-AR not only mediated the sympathetic nerves on the inotropic change of the heart,and the contraction of the vascular smooth muscles,bladder sphincter,and uterine smooth muscles and other physiological effect,but also mediated cardiac arrhythmia,myocardial hypertrophy and other pathological process.In addition,Alphal-AR also mediated the acupuncture signal transmission,and acupuncture was able to adjust the sympathetic nervous tension.The body's physiopathological changes are closely related to alpha1-AR and subtype alteration.The in-depth study of alphal-AR helps to explain physiopathological mechanism of the body,as well as provide theoretical basis and the corresponding pharmacological models for better selective drugs.Studying Alpha1-AR on meridians contributes to the discovery of meridian essence and the substantial basis of acupuncture effects.

OBJECTIVETo explore the change pattern of hypothalamic-pituitary-adrenal (HPA) axis and related neurotransmitters under simulated weightlessness.

METHODSA total of 40 clean-grade male Wistar rats were randomly divided into a normal group, a tail-suspension group, an electroacupuncture (EA) at Neiguan (PC 6) group, an EA at Sanyinjiao (SP 6) group, 10 rats in each group. Rats in the tail-suspension group, EA at "Neiguan" (PC 6) group and EA at "Sanyinjiao" (SP 6) group were treated with tail suspension to simulate weightlessness effect. Rats in the normal group were treated with normal diet. Rats in the tail-suspension group were treated with tail suspension for 28 d. During the time of tail suspension, rats in the EA at "Neiguan" (PC 6) group were treated with EA at "Neiguan" (PC 6), 30 min per treatment, once every two days for 14 treatments, while rats in the EA at "Sanyinjiao" (SP 6) group were treated with EA at "Sanyinjiao" (SP 6), 30 min per treatment, once every two days for 14 treatments. Samples were all collected after 4 weeks. The contents of corticotropin releasing hormone (CRH) , adrenocorticotropic hormone (ACTH), corticosterone (CORT) in as well as 5-hydroxy tryptamine (5-HT), dopamine (DA), norepinephrine (NE) were measured by using radioimmunoassay.

RESULTSCompared with the normal group, in the tail-suspension group the content of ACTH in pituitary was significantly decreased (P< 0.05), and the content of 5-HT in hypothalamus was significantly decreased (P < 0.01); the content of CRH and 5-HT in hypothalamus was significantly decreased (P < 0.01, P < 0.05) in the EA at "Neiguan" (PC 6) group; the content of CRH and 5-HT in hypothalamus was significantly decreased (P < 0.01), and the content of CORT in serum was significantly decreased (P < 0.05) in the EA at "Sanyinjiao" (SP 6) group. Compared with the tail-suspension group, the content of ACTH in hypothalamus was significantly decreased (P< 0.05) in the EA at "Neiguan" (PC 6) group; the content of CRH, ACTH and CORT was significantly decreased (P < 0.01, P < 0.05) in the EA at "Sanyinjiao" (SP 6) group. Compared with the EA at "Neiguan" (PC 6) group, the content of CORT was decreased (P < 0.05) in the EA at "Sanyinjiao" (SP 6) group.

CONCLUSIONEA can regulate the content of 5-HT in hypothalamus in tail-suspension rats, inhibit the hyperactivity of the HPA axis, in which EA at "Sanyinjiao" (SP 6) had more significant effects than "Neiguan" (PC 6), but no obvious effects on NE and DA were observed.

Objective To investigate the nutrition status, sleep quality, anxiety and depression in patients with chronic heart failure (CHF), and to analyze the relationships between them. Method Hospital anxiety and depression scale (HADS), mini nutritional assessment (MNA) and Pittsburgh sleep quality index (PSQI) were used to assess anxiety and depression, nutrition status and sleep quality in 118 CHF patients who were selected by convenience sanpling respectively. Results The score of anxiety of the patients was with a median of 5 (3, 8) and the score of depression was with a median of 5 (2, 8). Anxiety was present in 47 cases (39.8％). Depression was present in 48 cases (40.7％).MNA score was with an average of 21.5 ±3.5, 19 patients (16.1％) were malnourished, 59 patients (50.0％) were at risk of malnutrition and 40 (33.9％)well nourished. The MNA scores of patients with anxiety or depression were significantly lower than those with no anxiety or depression (P<0.001). The PSQI score in 118 patients was 6(4, 10), where 42(35.6％) were with sleep disorder and patients with depression and anxiety were higher than those without (P<0.01). The MNA score was negatively correlated with anxiety and depression (all P<0.001). The PSQI score was positively related with anxiety and depression (all P<0.01). Conclusions The prevalence of anxiety and depression was high in CHF patients. Both nutrition status and sleep quality were related to them. In the clinic work, medical workers should pay attention to the treatment of heart failure and the assessment of psychological status in heart failure patients with malnutrition or sleep disorders.

Objective:To analyze clinicopathological features of thyroid nodules and to assess preoperative diagnostic methods for the nature of nodules.Methods:The clinical and pathological data of 2 132 patients [456 males and 1 676 females with a mean age of (48.7±11.4) year] with thyroid nodules who underwent surgical treatment in our hospital from January 2017 to December 2019 were retrospectively analyzed. Among all patients, 433 nodules had complete fine needle aspiration biopsy cytology (FNAC) and ultrasound results were selected for further assessment. According to preoperative high-resolution ultrasound images, the nodules were classified by Kwak thyroid imaging and reporting data systems (Kwak TI-RADS) and American College of Radiology TI-RADS (ACR TI-RADS). ROC curve was used to assess the diagnostic efficacy of the two ultrasound modes and FNAC.Results:In 2 132 patients with thyroid nodules, 743 were benign and 1 389 were malignant. In all malignant cases 1 119 were females, accounting for 80.56%. In newly diagnosed benign nodules, 67.97% (505/743) were found by examination, and 32.03% (238/743) were self-found. In malignant nodules, 48.67% (676/1 389) were detected by examination, 51.33% (713/1 389) were self-found. The malignant rate of nodule diameter≤1 cm was the lowest in 1 118 patients with complete thyroid ultrasound data. In 628, 722 and 782 patients who underwent surgical treatment in 2017, 2018 and 2019, the proportion of malignant nodules was 56.37% (354/628), 66.48% (480/722) and 70.97% (555/782); the proportion of benign nodules was 43.63% (274/628), 33.52% (242/722) and 29.03% (227/782), respectively. Among all malignant nodules, papillary carcinoma accounted for 95.18% (1 322/1 389), followed by follicular carcinoma 4.32% (60/1 389), myeloid carcinoma 0.43% (60/1 389) and undifferentiated carcinoma 0.07%(1/1 389). Among all benign nodules, the proportion of nodular goiter was the highest (95.56%, 710/743). The proportion of patients undergoing preoperative FNAC in 2017, 2018 and 2019 was 57.96% (364/628), 63.43% (458/722) and 69.44% (543/782), respectively;the coincidence rate of preoperative FNAC and postoperative pathological diagnosis was 46.15% (168/364), 52.18% (239/458) and 62.06% (337/543), respectively. Among 433 nodules with both FNAC and ultrasound data, the areas under the ROC curve(AUC)of FNA, ACR TI-RADS and Kawk TI-RADS were 0.91, 0.74 and 0.59, respectively ( P<0.05). The sensitivity of ACR TI-RADS and Kawk TI-RADS was 84.34%, 37.35% ( P<0.05) and specificity was 56.29% and 79.14% ( P=0.075). Conclusions:The study reveals that from 2017 to 2019, both the number of cases and malignant rate of thyroid nodules shows a rising trend, meanwhile the application rate of preoperative FNAC and its coincidence rate with postoperative pathology shows an increasing trend. FNAC, ACR Ti-RADS and Kawk TI-RADS have certain diagnostic efficacy in differentiating benign and malignant thyroid nodules, and the diagnostic value of FNAC is the highest followed by ACR TI-RADS and Kawk TI-RADS.
