ABSTRACT

Objective:To investigate the impact of the interval period between biopsy and MR examination on tumor detection and extraprostatic extension (EPE) assessment for prostate cancer (PCa) using multi-parametric MRI (mpMRI).Methods:The study was cross-sectional and retrospectively included 130 patients with PCa who underwent RP and preoperative systematic biopsies followed by mpMRI between January 2021 and December 2022 in the First Medical Center of Chinese PLA General Hospital. Patients were divided into 3 groups according to interval following biopsy (group A,<3 weeks, 31 cases; group B, 3-6 weeks, 67 cases; group C,>6 weeks, 32 cases). The percentages of hemorrhage volume in the total prostate were drawn on T 1WI and calculated. The junior, senior and expert radiologists independently localized the index lesions and calculated the accuracy for tumor detection, in addition to assessing the probabilities of EPE according to EPE grade. The correlation between the hemorrhage extent and interval was analyzed using the Spearman correlation coefficient. The accuracy for tumor detection was compared using χ2 test among groups. The diagnostic performance of the radiologists for EPE prediction was assessed using the receiver operating characteristic curve, and the differences between the corresponding area under the curve (AUC) were compared using the DeLong test. Results:The percentage of hemorrhage was correlated with the interval between biopsy and MR examination ( r=-0.325, P<0.001). The detection accuracy of junior radiologist was 83.9% (26/31), 76.1% (51/67), and 78.1% (25/32) in group A, B and C, respectively; no differences were observed in the detection accuracy among three groups ( χ2=0.76, P=0.685). The detection accuracy of senior radiologist was 83.9% (26/31), 80.6% (54/67), and 71.9% (23/32) in 3 groups with no differences ( χ2=1.53, P=0.464). The detection accuracy of expert radiologist was 80.6% (25/31), 77.6% (52/67), and 93.8% (30/32) with no differences ( χ2=3.95, P=0.139). The AUC (95% CI) for predicting EPE were 0.830 (0.652-0.940), 0.704 (0.580-0.809), 0.800 (0.621-0.920) in the group A, B and C for junior radiologist; 0.876 (0.708-0.966), 0.768 (0.659-0.863), 0.896 (0.736-0.975) for senior radiologist; and 0.866 (0.695-0.961), 0.813 (0.699-0.895), 0.852 (0.682-0.952) for expert radiologist, respectively. No differences were observed among the subgroups in each radiologist ( P>0.05). Conclusion:The interval period does not significantly affect the detection accuracy and EPE assessment of PCa using mpMRI. There is probably no necessity for prolonged intervals following systematic biopsy to preserve the clarity of MRI interpretation for PCa.

ABSTRACT

OBJECTIVE@#To evaluate the trend of notified incidence of pulmonary tuberculosis (PTB) in China at different periods by population and region and to explore the effect of TB prevention and control in recent years.@*METHODS@#Using pooled data on TB cases reported by the TB Information Management Reporting System (TBIMS) from 2005 to 2020, we calculated the annual percentage change (APC) using the Joinpoint regression model.@*RESULTS@#From 2005 to 2020, a total of 16.2 million cases of PTB were reported in China, with an average notified incidence of 75.5 per 100,000 population. The age standardization rate (ASR) continued to decline from 116.9 (/100,000) in 2005 to 47.6 (/100,000) in 2020, with an average annual decrease of 5.6% [APC = -5.6, 95% confidence interval ( CI): -7.0 to -4.2]. The smallest decline occurred in 2011-2018 (APC = -3.4, 95% CI: -4.6 to -2.3) and the largest decrease in 2018-2020 (APC = -9.2, 95% CI: -16.4 to -1.3). From 2005 to 2020, the ASR in males (159.8 per 100,000 in 2005, 72.0 per 100,000 in 2020) was higher than that in females (62.2 per 100,000 in 2005, 32.3 per 100,000 in 2020), with an average annual decline of 6.0% for male and 4.9% for female. The average notified incidence was the highest among older adults (65 years and over) (182.3/100,000), with an average annual decline of 6.4%; children (0-14 years) were the lowest (4.8/100,000), with an average annual decline of 7.3%, but a significant increase of 3.3% between 2014 and 2020 (APC = 3.3, 95% CI: 1.4 to 5.2); middle-aged (35-64 years) decreased by 5.8%; and youth (15-34 years) decreased by an average annual rate of 4.2%. The average ASR in rural areas (81.3/100,000) is higher than that in urban areas (76.1/100,000). The average annual decline in rural areas was 4.5% and 6.3% in urban areas. South China had the highest average ASR (103.2/100,000), with an average annual decline of 5.9%, while North China had the lowest (56.5/100,000), with an average annual decline of 5.9%. The average ASR in the southwest was 95.3 (/100,000), with the smallest annual decline (APC = -4.5, 95% CI: -5.5 to -3.5); the average ASR in the Northwest China was 100.1 (/100,000), with the largest annual decline (APC = -6.4, 95% CI: -10.0 to -2.7); Central, Northeastern, and Eastern China declined by an average of 5.2%, 6.2%, and 6.1% per year, respectively.@*CONCLUSIONS@#From 2005 to 2020, the notified incidence of PTB in China continued to decline, falling by 55%. For high-risk groups such as males, older adults, high-burden areas in South, Southwest, and Northwest China, and rural regions, proactive screening should be strengthened to provide timely and effective anti-TB treatment and patient management services for confirmed cases. There is also a necessity to be vigilant about the upward trend of children in recent years, the specific reasons for which need to be further studied.

ABSTRACT

Objective@#To conduct a systematic review and meta-analysis of studies evaluating the oncological and fertility outcomes of early-stage endometrial cancer (EC) treated with the levonorgestrel-releasing intrauterine system (LIUS)-based regimens. @*Methods@#The Meta-analyses Of Observational Studies in Epidemiology statement for meta-analyses was followed. Searches were conducted on MEDLINE, Embase, PubMed, Preprints, and the Cochrane Central Register of Controlled Trials from January 1990 to August 4, 2022. The Joanna Briggs Institute Critical Appraisal Checklist was used for quality assessment. The primary endpoint was the complete response (CR) rate and the secondary endpoints were relapse, pregnancy, and live birth rate. @*Results@#A total of 25 studies (821 women) were included. The CR rate of LIUS-based regimens was 63.4% (95% confidence interval [CI]=52.3%–73.2%), with 29.6% (95% CI=23.3%–36.8%) of cases experiencing recurrence during follow-up. In sensitivity analyses, patients younger than 45 years of age with a body mass index <30 kg/m2 who were treated with LIUS-based regimens achieved a high CR rate of 84.6% (95% CI=80.3%–88.1%) over a median follow-up of more than 24 months. Overall pregnancy and live birth rates were 37.9% (95% CI=24.1%–53.9%) and 39.3% (95% CI=24.0%–57.0%), respectively. No statistical differences were apparent in CR or relapse rates among the LIUS+GnRH agonist, LIUS+oral progesterone, or hysteroscopic resection followed by LIUS subgroups. @*Conclusion@#LIUS-based therapies are viable for the conservative management of early-stage endometrioid EC on CR and fertility outcome.

ABSTRACT

Objective:To build a simple, rapid and accurate visual prediction model for identifying the ST-segment elevation myocardial infarction (STEMI) patients with high risk of no reflow during the primary percutaneous coronary intervention (PPCI).Methods:A retrospective study of STEMI patients treated by PPCI in China-Japan Friendship Hospital from January 2018 to June 2019 was performed. The clinical data including sex, age, comorbidities, personal history, Killip classification and laboratory examinations were collected. Whether the patients had no reflow during the PPCI were retrospective observed. Multivariable logistic regression analysis was used to identify risk factors. A nomogram was developed to predict no reflow risk among STEMI patients. C-index and Hosmer-Lemeshow goodness-of-fit test were used to verify the differentiation, consistency and clinical applicability of the model. Internal verification of the model was used by Bootstrap validation.Results:Of the included 280 patients, the prevalence of no flow rate was 30.7%. Killip class Ⅲ or Ⅳ ( OR=3.537, 95% CI: 1.665-7.514, P=0.002), mean platelet volume≥9 fL ( OR=4.003, 95% CI: 1.091-14.689, P=0.037), Glucose ≥7.8 mmol/L ( OR=2.315, 95% CI: 1.318-4.066, P=0.003) and time from symptoms to hospital ( OR=5.594, 95% CI: 2.041-15.328, P=0.002) were the independent risk factors of no flow (all P<0.05). The AUC of ROC curve in the prediction model was 0.731 (95% CI: 0.668-0.795). The calibration curves were close to the standard curve. Conclusions:The visual prediction model constructed in this study can early identify STEMI patients with high risk of no reflow, and may be helpful for physicians to provide prospective pre-treatment before the occurrence of no reflow during PPCI.

ABSTRACT

Objective:To investigate the potential factors influencing the extent of coronary artery lesion in acute coronary syndrome (ACS) patients with an emphasis on the role of serum SIRT1.Methods:We assessed the clinical data from 81 ACS patients admitted to China-Japan Friendship Hospital. Serum SIRT1 was detected by enzyme linked immunosorbent assay (ELISA), and the extent of coronary artery lesion was evaluated by SYNTAX score before revascularization. All the patients were divided into two groups: high SYNTAX score (severe coronary artery lesion, n=38) and low SYNTAX score (moderate coronary artery lesion, n=43), by means of the median of SYNTAX score. Potential factors influencing SYNTAX score were analyzed through multiple linear regression analysis. Results:Compared with the low SYNTAX score group, patients in the high SYNTAX score group had higher serum SIRT1 level [379.38 (490.14) ng/L vs. 242.95 (173.85) ng/L, P<0.001] and frequency of coronary artery disease family history (42.11% vs. 20.93%, P=0.039). There was no statistical difference among other factors between the two groups. Serum SIRT1 was positively correlated with SYNTAX score in ACS patients ( R=0.452, P<0.010). Serum SIRT1 (ln adjusted), age and estimated glomerular filtration rate were independently correlated with SYNTAX score (ln adjusted) in multiple linear regression analysis (Adjusted R2=0.330, P<0.001). Conclusions:For the first time, we discussed the correlation of serum SIRT1 with extent of coronary artery lesion in ACS patients. Cardiologists should pay more attention to high-risk patients in order to improve the prognosis of ACS patients through timely revascularization strategies.

ABSTRACT

Objective Hilar cholangiocarcinoma (HC) is invariably fatal without surgical resection. The primary aim of the current study was to determine the safety of variable surgical resections for patient with HC and their survival after surgical resection. In addition, prognostic factor for the overall survival was also evaluated. Methods The study included 59 consecutive patients who were newly diagnosed with HC and underwent surgical resections with curative intend between February 2009 and February 2017. Patients were followed up at 3-6 months intervals after hospital discharge. Postoperative complications and overall survival were determined. Associations of clinicopathologic and surgeon-related factors with overall survival were evaluated through univariate analysis and Cox regression analysis. Results Of patients with Bismuth and Corlette (B & C) type Ⅲ (=19) and Ⅳ (=25) HC lesions, 33 (55.9%) were treated with hilar resection combined with major liver resection (MLR), while the other 11 patients with type Ⅲ and Ⅳ, and those with type Ⅰ (=8) and Ⅱ (=7) HC lesions were treated with hilar resection. The overall surgical mortality was 5.1% and surgical morbidity was 35.6%. There was no statistical difference in the mortality between MLR group and hilar resection group (6.1% 3.8%; =0.703, =0.145). The median follow-up period was 18 months (range, 1-94 months). The 1-, 3-, 5-year survival rate was 59.3%, 36.5%, and 17.7%, respectively. The overall survival after resections was 18 months. In HC patients with B & C type Ⅲ and Ⅳ lesions, the median survival was 23 months for hilar resection with MLR and 8 months for hilar resection alone; the 1-, 3-, 5-year cumulative survival rate was 63.9%, 23.3%, and 15.5%, respectively for hilar resection with MLR, and 11.1%, 0, and 0, respectively for hilar resection alone, with significant differene observed (, 9.902; 95% , 2.636-19.571, =0.001). Four factors were independently associated with overall survival: preoperative serum Ca19-9 (, 7.039; 95% , 2.803-17.678, <0.001), histopathologic grade (, 4.964; 95% , 1.046-23.552, =0.044), surgical margins (=0.031), and AJCC staging (=0.015). Conclusions R0 resection is efficacious in surgical treatment of HC. MLR in combination with caudate lobe resection may increase the chance of R0 resection and improve survival of HC patients with B & C type Ⅲ and Ⅳ lesions. Preoperatively prepared for biliary drainage may ensure the safety of MLR in most HC patients. Novel adjuvant therapies are needed to improve the survival of HC patients with poor prognostic factors.

ABSTRACT

Objective To analyze the epidemic trend of hepatitis B virus (HBV) in 18 minority nationalities in Yunnan Province from 2009 to 2018, so as to explore the ethnic differences in the incidence of HBV in Yunnan Province. Methods Based on the reported incidence data of hepatitis B in China's disease prevention and control information system from 2009 to 2018, descriptive epidemiology method was used to describe and analyze the incidence of hepatitis B in different ethnic groups, and K-means clustering method was used to explore and analyze the annual average incidence of hepatitis B in different ethnic groups. Results From 2009 to 2018, the average incidence of hepatitis B in Yunnan Province was 44.26/100 000, which was much lower than the overall level of China every year; the average incidence of hepatitis B in ethnic groups was 41.27/100 000, slightly lower than the overall level of Yunnan every year. The prevalence of hepatitis B was different in different ethnic groups. The average incidence of Wa was significantly higher than others (95.26/100 000), and Jingpo was the lowest (22.51/100 000). According to the incidence of hepatitis B, different ethnic groups were divided into three categories: high incidence ethnic group, middle incidence ethnic group and low incidence ethnic group. Conclusion There are ethnic differences in the incidence of hepatitis B in Yunnan Province. The incidence of hepatitis B in some ethnic groups is higher than that in the whole country all the year round, which is the key population in the prevention and control of hepatitis B.

ABSTRACT

Objective:To explore the effective ability and strategy of improving in-hospital emergency in large general hospitals through investigating and analyzing the epidemiological characteristics and outcomes of patients treated by rapid response team (RRT) in the Fourth People's Hospital of Shenyang.Methods:The clinical data of 145 patients treated by RRT in the Fourth People's Hospital of Shenyang from April 1st to June 30th in 2019 were retrospectively analyzed. The clinical data including gender, age, RRT response time, disease type, direct cause of RRT initiation, the incidence of cardiac arrest, intensive care unit (ICU) admission rate and outcome were statistically analyzed. The correlation between indicators was analyzed by Pearson correlation. Pareto diagram was used to analyze the direct cause of RRT initiation.Results:A total of 145 patients were treated by RRT within 3 months. The ratio of male ( n = 85) to female ( n = 60) was 1.42∶1. The age of patients treated by RRT was (72.83±14.84) years old, and the response time was (3.27±1.42) minutes. The incidence of cardiac arrest was 23.4% (34/145), and the ICU admission rate was 29.7% (43/145). The hospital mortality was 40.0% (58/145), and the rescue success rate was 60.0% (87/145). Correlation analysis showed that there was a significant positive correlation between the incidence of cardiac arrest and hospital mortality ( r = 0.545, P < 0.01). According to the disease type of patients treated by RRT analysis, respiratory system diseases ( n = 44, 30.3%) accounted for the most, followed by circulatory system diseases ( n = 43, 29.7%), nervous system diseases ( n = 25, 17.2%), digestive system diseases ( n = 19, 13.1%), trauma ( n = 5, 3.4%), endocrine system diseases ( n = 3, 2.1%), urinary system diseases ( n = 2, 1.4%) and others ( n = 4, 2.8%). Further analysis showed that patients aged between 85 years old and 94 years old were prone to the respiratory system diseases, accounting for 48.5% (16/33) of the population in this age group, while the cardiovascular system diseases were the most common in patients older than 55 years old, accounting for 31.0% (40/129) of the population in this age group. Pareto diagram showed that the percentages of direct causes of RRT initiation ranked from high to low, the cumulative percentage of pneumonia ( n = 30, 20.7%), acute myocardial infarction ( n = 26, 17.9%), stroke ( n = 20, 13.8%), septic shock ( n = 14, 9.7%), heart failure ( n = 10, 6.9%), respiratory and cardiac arrest ( n = 9, 6.2%), and gastrointestinal bleeding ( n = 7, 4.8%), which were the main direct causes of RRT initiation with a total of 80%. Conclusions:Respiratory system and circulatory system diseases are the main causes for RRT treatment in first-aid patients in the Fourth People's Hospital of Shenyang. The hospital mortality significantly increases once patients suffered cardiac arrest. The RRT can provide effective intervention earlier and faster, and establish a complete RRT emergency strategy, which is helpful to improve the in-hospital emergency ability in large general hospitals.

ABSTRACT

This paper aims to investigate the effect of oral administration of Tripterygium Glycosides Tablets combined with traditional Chinese medicine on immune inflammatory index in patients with rheumatoid arthritis,in order to explore the compatibility mode of traditional Chinese medicine in the treatment of rheumatoid arthritis. Medical records of hospitalized patients with rheumatology at the First Affiliated Hospital of Anhui University of Traditional Chinese Medicine from June 2012 to December 2017 were collected. The combined administration of Tripterygium Glycosides Tablets and traditional Chinese medicine was adopted for the experimental group,while the simply administration of Tripterygium Glycosides Tablets were adopted for the control group. SPSS 21. 0 was used to analyze the changes of general conditions and immune inflammatory metabolic indexes in the two groups of RA patients. The association rules were analyzed by SPSS Clementine 14. 2 software Apriori module,and the random walk model was evaluated by ORACLE 10 g tool. The results showed that a total of 1 220 patients with rheumatoid arthritis met the requirements of this study,including 322 in the experimental group and 898 in the control group. Before treatment,there was no significant difference in age and duration between the two groups. The difference value of Ig A,Ig G,RF,CCP-AB,hs-CRP and ESR in the two groups of RA patients decreased before and after treatment,and the experimental group was superior to the control group in reduction of Ig A,Ig G,RF,CCP-AB,hs-CRP and ESR.The control group was superior to the experimental group in reduction of Ig M( P<0. 01 or P<0. 05). Compared with before treatment,ALT,AST,ALP,GGT,CREA,BUN,b-MG,MA,TRU and Ig U all increased,with statistically significant differences( P<0. 01).The UA of the two groups of RA patients decreased after treatment,with statistically significant differences( P<0. 01). The experimental group was superior to the control group in reduction of UA,with statistically significant differences( P < 0. 05 or P < 0. 01). The herbs adopted in the prescriptions of 1 220 patients were mainly classified into four categories,namely spleen-sweating herbs,blood-activating and stasis-relieving herbs,phlegm and phlegm-relieving herbs,and heat-clearing and antidote herbs. The results of association rule analysis indicated a significant correlation between the single-flavored Tripterygium Glycosides Tablets,oral Chinese medicine and immune inflammation,and improvement of liver and kidney function indexes. The results of the random walk model analysis indicated that the experimental group's Ig M and hs-CRP were superior to those of the control group in terms of random fluctuation maximum,walking positive growth rate,comprehensive evaluation index increasing rate,comprehensive improvement rate,comprehensive evaluation index recording times,and expected improvement value. The results of this study showed that the single administration of Tripterygium Glycosides Tablets can effectively improve the immune inflammatory metabolic index of patients with rheumatoid arthritis,and the combined administration of Tripterygium Glycosides Tablets and traditional Chinese medicine could alleviate the immune inflammatory index of RA patients and reduce liver and kidney dysfunction compared with simple oral administration. The comprehensive evaluation Ig M and hs-CRP in the group of combined administration of Tripterygium Glycosides Tablets and traditional Chinese medicine were better than those in the group of the Tripterygium Glycosides Tablets. There was a long-term correlation between the comprehensive evaluation index and the intervention measures of the two groups of patients.

ABSTRACT

The effect of triptolide( TP) on VEGFA,SDF-1,CXCR4 pathway were investigated in vitro to explore the mechanism in improving platelet activation in patients with ankylosing spondylitis( AS). Peripheral blood mononuclear cells( PBMC) were used for the experiment and divided into 4 groups: normal group( NC),model group( MC),triptolide group( TP),and AMD3100 group. The optimal concentration of TP was measured by the MTT method. The expressions of TNF-α,IL-1β,IL-4,IL-10,VEGFA and VEGFR were detected by ELISA. The expressions of SDF-1,CXCR4 and VEGFA were detected by real-time quantitative PCR( RT-qPCR).The expressions of SDF-1,CXCR4,VEGFA and VEGFR were detected by Western blot. The expression levels of CD62 p,CD40 L and PDGFA were detected by immunofluorescence. MTT results showed that medium-dose TP had the strongest inhibitory effect on cells at24 h. The results of ELISA and PCR showed that TP inhibited mRNA expressions of IL-1β,TNF-α,VEGFA,VEGFR and SDF-1,CXCR4 and VEGFA. The results of Western blot indicated that TP inhibited SDF-1,CXCR4 and VEGFA,VEGFR protein expressions; immunofluorescence results indicate that TP can inhibit the expressions of CD62 p,CD40 L,PDGFA. TP may regulate platelet activation by down-regulating SDF-1,CXCR4,VEGFA and VEGFR mRNA expressions,thereby down-regulating IL-1β and TNF-αexpressions,and up-regulating the expressions of IL-4 and IL-10 cytokines.

ABSTRACT

To evaluate the effect of traditional Chinese medicine(TCM) invigorating spleen unit therapy on inflammatory markers of osteoarthritis(OA) patients by random walk model. The patient information was collected by the data processing system of medical records of the First Affiliated Hospital of Anhui University of Traditional Chinese Medicine. In-patient information of the department of rheumatology of the hospital between June 2012 and December 2016 was collected and summarized. Based on the use of traditional Chinese medicine decoction and hospital-prepared compound Qiyi Capsules(Xinfeng Capsules),the patients were divided into the unit therapy group and the simple endotherapy group. The random walk model was used to evaluate the effect of traditional Chinese medicine invigorating spleen unit therapy on TCM spleen therapy unit(ESR) and high sensitive C reactive protein(hs-CRP). A total of 3 517 cases of OA patients met the study requirements. The simple endotherapy group had 1 771 cases(50. 36%),while the unit therapy group had 1 746 cases(49. 64%). The baseline data analysis showed that the general information of the cases,the TCM oral intake frequency and the core prescription information had no statistically significant difference,with comparability. The unit therapy group showed the maximum ESR stochastic volatility at 924,walking step number of 1 771,forward walking growth rate at 0. 264 5,ratio at3. 78,random fluctuation power law at 0. 306 5± 0. 076 8,positive increase rate of comprehensive evaluation index at 0. 264 5,and comprehensive evaluation index record number of 1 771; whereas the simple endotherapy group showed the maximum ESR random fluctuation value at 478,walking step number of 1 399,forward walking growth rate at 0. 152 4,ratio at 6. 56,random fluctuation power law at 0. 347 4±0. 101 7,positive increase rate of comprehensive evaluation index at 0. 152 4,and comprehensive evaluation index record number of 1 399. The unit therapy group showed the maximum hs-CRP random fluctuation value at 391,walking step number of1 081,forward walking growth rate at 0. 178 1,ratio at 5. 62,random fluctuation power law at 0. 343 6±0. 094 7,positive increase rate of comprehensive evaluation index at 0. 178 1,and comprehensive evaluation index record number of 1 081; while the simple endotherapy groups showed the maximum hs-CRP random fluctuation value at 210,walking step number of 797,forward walking growth rate at0. 113 2,ratio at 8. 83,random fluctuation power law at 0. 382 6±0. 109,positive increase rate of comprehensive evaluation index at0. 113 2,and comprehensive evaluation index record number of 797. According to our department of rheumatism,there was a longrange correlation between the two groups in the comprehensive evaluation index and the intervention measures. TCM spleen strengthening unit therapy has a better effect in alleviating the inflammatory index of OA than traditional Chinese medicine.

ABSTRACT

This study is to investigate the effect of antidepressant medicine prescription Dingzhi Xiaowan (DZ) on miR-16 expression levels in vitro and in vivo, and to explore the mechanism of DZ elevated levels of 5-HT from the perspective of post transcriptional regulation. Firstly, a chronic unpredictable mild moderate stimulation (CUMS) combined with solitary rising depression rat model was established, the behavior changes were detected after different doses of DZ (600, 300, 150 mg·kg⁻¹) given for 3 weeks, high performance liquid chromatography (HPLC) was used to detect 5-HT level in hippocampal, PCR method was used to observe the effect of DZ on the expression of SERT mRNA and miR-16 in hippocampus of CUMS rat. The effects of DZ (10, 100, 200, 500 mg·L⁻¹) on the expression of miR-16 and SERT mRNA in the cell model induced by miR-16 silencing and corticosterone or glutamate injury were observed in primary cultured hippocampal neurons of rats in vitro. It was found that 300 mg·kg⁻¹ and 600 mg·kg⁻¹ DZ could significantly improve the behavioral score of CUMS rats, increase the level of 5-HT in hippocampus, and increase the expression of miR-16 and decrease the expression of SERT in the hippocampus of rats. At the same time, in primary cultured hippocampal neurons, 100, 200, 500 mg·L⁻¹ of DZ could significantly increase the expression level of miR-16 in miR-16 silencing and corticosterone or glutamate injury cell model, and decrease the expression level of SERT significantly. So DZ could inhibit the reuptake of 5-HT by inhibiting the expression of SERT by up regulating the expression level of miR-16, and finally increase the level of 5-HT in the brain and exert antidepressant effect.

ABSTRACT

To observe the effect of antidepressant medicine prescription, Kaixinsan (KXS) on monoamine oxidase (MAO) activity, and explore the mechanism of KXS in elevating the levels of monoamine neurotransmitter from the perspective of metabolism, in vitro enzyme reaction system and C6 neuroglial cells, the effect of KXS at different concentrations on MAO-A and MAO-B activity was observed. In animal studies, the effect of KXS at different concentrations on MAO-A and MAO-B activities of brain mitochondrialin normal rats and solitary chronic unpredictable moderate stress (CMS) model rats after intragastric administration for 1, 2, 3 weeks. Results showed that 10 g•L⁻¹ KXS could significantly reduce the activity of MAO-A and MAO-B in enzyme reaction system; and in C6 cells, KXS within 0.625-10 g•L⁻¹ concentration range had no significant effect on the activity of MAO-A, but had obvious inhibitory effect on the activity of MAO-B in a dose dependent manner. KXS had no significant effect on the activity of MAO-A and MAO-B in brains of normal rats after action for 1, 2, 3 weeks. After 2 and 3 weeks treatment with 338 mg•kg⁻¹ dose KXS, MAO-A activity in the brain of CMS rats was decreased as compared with the model group (P<0.05), while KXS had no significant effect on MAO-B activity after 1, 2, 3 weeks of treatment. The results indicated that KXS had certain effect on in vitro MAO-A and MAO-B activity, had no effect on brain MAO-A and MAO-B activity in vivo in normal rats, and had certain inhibitory effect on MAO-A activity in brains of CMS rats.

ABSTRACT

To study the anti-radiation effect and mechanism of ethanol extracts from Spatholobus suberectus and its active component catechin, ICR mice were exposed to 6Gy irradiation and randomly divided into normal group, model group, positive control group (amifostine, 43.6 mg•kg⁻¹, iv 30 min before irradiation), SSD group (10, 20, 40 g•kg⁻¹) and catechin group (50, 100, 200 mg•kg⁻¹). The mice were administered the appropriate drugs once a day after irradiation for 28 consecutive days. Blood samples were collected from the tail end and the number of peripheral blood cells was counted before irradiation and on day 1, 3, 7, 14, 21 and 28 using a microcell counter. Changes of thymus and spleen index of mice on day 7 were observed. The serum SOD, GSH-Px activity and MDA level were detected by the colorimetric method. The colony forming ability of bone marrow hematopoietic progenitor cells on day 7 was detected by semi solid culture method. The HE staining was adopted to observe the pathological changes. The apoptosis of bone marrow cells was detected by flow cytometry. The expression of cleaved caspase-3 and Bax of bone marrow cells were measured separately by western-blotting and immunohistochemistry method. SSD and catechin can both significantly revert the irradiated-induced decline in hematological parameters (RBC, WBC, PLT, Hb), improve thymus and spleen index, significantly enhance serum SOD and GSH-Px activity and decrease the MDA level. The proliferation and differentiation of hematopoietic progenitor cells in bone marrow were promoted, the apoptosis of bone marrow cells was significantly up-regulated and the expression of cleaved caspase-3 and Bax was significantly reduced in SSD and catechin group. SSD and catechin have significant anti-radiation effect and its mechanism may be related to hematopoietic promoting, antioxidant and anti-apoptotic effects.

ABSTRACT

BACKGROUND:Some control studies attempt to answer the advantages and disadvantages of high-dose methylprednisolone sodium succinate therapy for acute spinal cord injury in adults, but have arrived at different conclusions. OBJECTIVE:To explore the therapeutic efficacy of high-dose methylprednisolone sodium succinate therapy on acute spinal cord injury in adults by Meta analysis. METHODS:PubMed, Embase, Cochranel Library, CBMdisc, VIP and WanFang Databases were searched by computer, and relevant Chinese and English orthopedic journals were retrieved by hand. Controled trials related to high-dose methylprednisolone sodium succinate therapy of acute spinal cord injury in adults were included. The methodology quality of included trials was criticaly assessed. RevMan 5.0 software was used for data analysis. RESULTS AND CONCLUSION:Nine clinical controled trials were included. Meta-analysis results showed that compared with the conventional therapy, the neurological recovery rate after 24 hours of administration, pneumonia incidence and gastrointestinal reactions increased significantly after high-dose methylprednisolone sodium succinate therapy. However, there were no statistical differences in the rate of urinary tract infection, nonunion rate and stress ulcer incidence between these two therapies. These findings indicate that the high-dose methylprednisolone sodium succinate therapy on acute spinal cord injury in adults has better outcomes in neurological function recovery, but can lead to higher incidence of lung infection and gastrointestinal reactions. Therefore, lung infection and gastrointestinal reactions should be avoided as much as possible during the course of treatment.

ABSTRACT

Dingzhi Xiaowan is a widely used traditional Chinese medicine in treating depression, which is a similar formula of Kaixinsan. In this research, a rapid ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF/MS(E)) method was established to analyze the metabolites of Dingzhi Xiaowan in depressive model rat plasma, bile, urine and feces. After we established Chronic unpredictable mild stress (CUMS) model rats and orally administrated Dingzhi Xiaowan, rat plasma, bile, urine and feces samples were collected and prepared. Using Waters Cortects UPLC C18 column (2.1 mm x 50 mm, 1.6 μm), acetonitrile-0.1% formic acid mobile phase gradient, these samples were analyzed and 33 metabolites of nine bioactive compounds were detected and tentatively identified by Metabolynx. Among the 33 metabolites, three metabolites were identified from plasma sample, three came from bile sample, and 27 metabolites were identified from urine and feces samples. This approach provided a rapid method for characterizing the metabolites of Dingzhi Xiaowan and gave the truly active structures and the action mechanism of their antidepressant effects.
