ABSTRACT
The mild-natured and bitter-flavored traditional Chinese medicines (MB-TCMs) are an important class of TCMs that have been widely used in clinical practice and recognized as safe long-term treatments for chronic diseases. However, as an important class of TCMs, the panorama of pharmacological effects and the mechanisms of MB-TCMs have not been systemically reviewed. Compelling studies have shown that gut microbiota can mediate the therapeutic activity of TCMs and help to elucidate the core principles of TCM medicinal theory. In this systematic review, we found that MB-TCMs commonly participated in the modulation of metabolic syndrome, intestinal inflammation, nervous system disease and cardiovascular system disease in association with promoting the growth of beneficial bacteria Bacteroides, Akkermansia, Lactobacillus, Bifidobacterium, Roseburia as well as inhibiting the proliferation of harmful bacteria Helicobacter, Enterococcus, Desulfovibrio and Escherichia-Shigella. These alterations, correspondingly, enhance the generation of protective metabolites, mainly including short-chain fatty acids (SCFAs), bile acid (BAs), 5-hydroxytryptamine (5-HT), indole and gamma-aminobutyric acid (GABA), and inhibit the generation of harmful metabolites, such as proinflammatory factors trimethylamine oxide (TAMO) and lipopolysaccharide (LPS), to further exert multiplicative effects for the maintenance of human health through several different signaling pathways. Altogether, this present review has attempted to comprehensively summarize the relationship between MB-TCMs and gut microbiota by establishing the TCMs-gut microbiota-metabolite-signaling pathway-diseases axis, which may provide new insight into the study of TCM medicinal theories and their clinical applications.
ABSTRACT
Objective:To observe the clinical efficacy of micro-needle therapy combined with Biotrisse BTS Lumin OX and Biotrisse BTS Brightline in the treatment of melasma.Methods:From September 2019 to June 2021, 80 patients with facial chloasma, aged 28-48 (37.3±4.9) years, were selected from Nanjing Jiangning Guze Clinic. The micro-needle therapy was combined with lumin OX and brightline for 6 times, and the observation time was 120 days. The mMASI score and VISIA photos before and after treatment were used to improve the results.Results:Eighty patients with refractory melasma on the face were treated with micro-needle therapy for 7 times (1 time per week for the first 5 times, and twice a week for the 9th and 10th weeks). The photos before and after treatment were compared and the mMASI of the patients' facial chloasma was compared. The scores were analyzed statistically, and the melasma were improved to varying degrees. Before treatment, the mMASI score was 5.4±3.22; 90 days later, the mMASI was 3.22±2.16, and the score decreased significantly ( t=5.9, P<0.05); after 120 days, mMASI score was 1.6±0.68, and the score decreased significantly ( t=7.55, P<0.05). Pigmentation occurred in one patient after treatment, and hypopigmentation after repair treatment; none of the patients had adverse reactions such as hypopigmentation. All the 80 patients had different degrees of improvement in pores and skin texture. Conclusions:The combination of micro-needling with lumin OX and brightline in the treatment of chloasma has a definite effect without obvious side effects. It provides a new method for the treatment of chloasma.
ABSTRACT
OBJECTIVE@#To explore the prognostic value of early multiple detection indicators in combination with sequential organ failure assessment (SOFA) in sepsis patients.@*METHODS@#A retrospective analysis was conducted. Patients with sepsis admitted to the department of critical care medicine of Huanggang Central Hospital of Yangtze University from May 2020 to May 2022 were selected as the research subjects. Coagulation indicators, inflammatory factors, blood routine, liver and kidney function, and blood gas analysis were collected at admission. Organ dysfunction was assessed based on the SOFA score within 24 hours after admission. Patients were divided into a survival group and a death group according to the outcome of 28 days in ICU. Differences in the above indicators between the two groups were compared. Multifactorial Logistic regression analysis was used to analyze prognostic factors of 28-day mortality in sepsis patients. Receiver operator characteristic curve (ROC curve) was drawn to analyze the predictive performance of various indicators, the SOFA score, and the combine model for the 28-day outcome in patients with sepsis.@*RESULTS@#A total of 101 patients with sepsis were enrolled, 56 patients survived and 45 patients died. Compared to the survival group, patients in the death group were older, the proportion of patients with septic shock was larger, the SOFA score, and the proportion of pulmonary infection were higher, the prothrombin time (PT) and activated partial thromboplastin time (APTT) were significantly prolonged, the prothrombin activity (PTA) was significantly shortened, and antithrombin (AT) was significantly decreased, the levels of hypersensitivity C-reactive protein (hs-CRP), blood urea nitrogen (BUN), total bilirubin (TBil), and lactic acid (Lac) were significantly increased, while the platelet count (PLT) was significantly decreased. Multifactorial Logistic regression analysis showed that pulmonary infection [odds ratio (OR) = 0.010, 95% confidence interval (95%CI) was 0.001-0.164, P = 0.001], AT (OR = 0.944, 95%CI was 0.910-0.978, P = 0.002), hs-CRP (OR = 1.008, 95%CI was 1.001-1.015, P = 0.017), Lac (OR = 1.619, 95%CI was 1.195-2.193, P = 0.002), and SOFA score (OR = 1.363, 95%CI was 1.076-1.727, P = 0.010) were independent prognostic factors for 28-day mortality in patients. A combined model was constructed using pulmonary infection, AT, hs-CRP, Lac, and SOFA score. ROC curve analysis showed that the area under the ROC curve (AUC) for the combine model in predicting sepsis prognosis was 0.936 (95%CI was 0.869-0.975, P < 0.001), which was higher in value compared to single indicators (AUC of AT, hs-CRP, Lac, and SOFA score were 0.775, 0.666, 0.802, 0.796, respectively, all P < 0.05).@*CONCLUSIONS@#The predictive ability of the SOFA score for sepsis patient outcomes is limited. The combine model combining infection site, AT, hs-CRP, and Lac shows better predictive ability.

OBJECTIVE@#Gut microbiome is an intricate micro-ecosystem mediating the human health and drug efficacy. Physalis alkekengi (PAL) is an edible and time-honored traditional Chinese medicine. Several pharmacological effects of PAL have been verified and gut bacteria are implied in its therapeutic actions. However, the detailed modulation of PAL on gut bacterial species and on gut fungi remains largely unknown. We, therefore, designed a preliminary experiment in normal mice to reveal the modulation effect of PAL on both gut bacteria and fungi, and explore the interaction between them.@*METHODS@#Herein, the aqueous extract of PAL was orally administrated to normal C57BL/6 mice for four weeks. The full-length 16S rRNA and ITS1/2 gene sequencing were explored to detect the taxa of gut bacteria and gut fungi after PAL treatment, respectively.@*RESULTS@#Oral administration of PAL notably enriched anti-inflammatory bacterial species such as Duncaniella spp. and Kineothrix alysoides, whereas decreased pro-inflammatory species such as Mucispirillum schaedleri. Simultaneously, PAL increased the abundance of gut fungi Aspergillus ochraceus, Cladosporium sp. and Alternaria sp., and decreased Penicillium janthinellum. Correlation network analysis identified two co-existing microbial groups (groups 1 and 2) that were negatively associated with each other. The group 1 comprised PAL-enriched bacteria and fungi, while group 2 was mainly normal chow-enriched bacteria and fungi. In group 1, Antrodia monomitica, Aspergillus clavatus, Mortierella kuhlmanii and Sarcinomyces sp. MA 4787 were positively correlated with Bifidobacterium globosum, Romboutsia ilealis and so on. In group 2, Chaetomium subspirilliferum, Septoria orchidearum and Cephaliophora tropica were positively related to Lactobacillus spp.@*CONCLUSION@#Altogether, this preliminary study first demonstrated the modulation effect of PAL on both gut bacteria and gut fungi, which may shed light on the elucidation of PAL's pharmacological mechanism.
ABSTRACT
Objective:To evaluate the differential diagnostic efficacy of a predictive model of breast imaging reporting and data system (BI-RADS) classification combined with mammography radiomics classifier for various X-ray phenotype of breast lesions.Methods:A retrospective analysis was performed on 2 055 female patients who underwent mammography examination and were confirmed by pathology from May 2013 to August 2020 in Zhongda Hospital, Southeast University. Breast lesion was classified into mass or non-mass according to the fifth edition of BI-RADS. The mass was further divided into small mass (maximum diameter ≤ 2 cm) and large mass (maximum diameter>2 cm), the non-mass was further divided into asymmetric, calcification and structural distortions. By manually segmenting the region of interest of the lesion, the radiomics features were extracted and the model was constructed. Receiver operating characteristic curve and area under the curve (AUC) were used to assess the diagnostic efficacy of the BI-RADS classification, the radiomics model and the combined model for various phenotypes of breast lesions. Differences among the AUC were analyzed by the DeLong test.Results:The AUCs based on the BI-RADS classification, the radiomics model and the combined model were 0.924±0.006, 0.827±0.009 and 0.947±0.005 respectively. Compared with BI-RADS classification and the radiomics model, AUC of the combined model was the highest, and the differences were statistically significant ( Z=9.29, 14.94, P<0.001). For large mass, small mass and non-mass, combined model (AUC=0.958±0.007, 0.933±0.013, 0.939±0.008) showed the best performance when compared to the BI-RADS classification (AUC=0.937±0.010, 0.896±0.020, 0.916±0.011; Z=5.32, 3.90, 5.08, P<0.001) or the radiomics model (AUC=0.872±0.012, 0.851±0.021, 0.758±0.016; Z=7.86, 4.53, 12.13, P<0.001). The AUC of the combined model for benign and malignant asymmetric breast lesions (0.897±0.017) was higher than that of the BI-RADS classification (AUC=0.866±0.020, Z=4.27, P<0.001) and the radiomics model (AUC=0.633±0.029, Z=7.44, P<0.001); however, the AUC of the combined model for benign and malignant calcification and structural distortion of breast lesions (0.971±0.010, 0.811±0.057, respectively) was only higher than that of the radiomics model (AUC=0.827±0.021, 0.586±0.075, Z=7.40, 3.15, P<0.001), and there was no significant difference with the BI-RADS classification (AUC=0.959±0.012, 0.800±0.061, Z=1.87, 0.39, P>0.05). Conclusion:The combined model shows better differential diagnostic performance, which is valued in the clinical application.
ABSTRACT
Objective:To investigate the expression levels of serum soluble triggering receptor expressed on myeloid cells 2(sTREM2)in patients with vascular dementia(VD)and its relationship with β-amyloid 1-42(Aβ1-42)and lipoprotein-associated phospholipase 2(Lp-PLA2), as well as its value in diagnosis and differential diagnosis.Methods:A total of 152 patients with ischemic stroke receiving routine treatment in our hospital from January 2018 to January 2020 were included and divided into a VD group(n=76)and a non-VD group(n=76)according to evaluation from subsequent visits at 3 months.General data, Mini-Mental State Examination Scale(MMSE), Hachinski Ischemic Scale(HIS)scores, and the levels of biochemical indicators were compared and analyzed for the two groups.Results:There were statistically significant differences in lesion size between the VD group and the non-VD group( P<0.05). The MMSE score in the VD group was significantly lower than that in the non-VD group.The HIS score, serum levels of sTREM2[(3.34±1.18)μg/L and(2.78±1.25)μg/L, t=2.121, P=0.036], Aβ1-42[(93.69±14.45)ng/L and(81.24±14.21)ng/L, t=4.003, P<0.001]and Lp-PLA2 levels[(58.67±14.15)μg/L and(43.18±13.86)μg/L, t=5.096, P<0.001]were significantly higher in patients with VD than in patients without VD( P<0.05). Serum sTREM2 was positively correlated with Aβ1-42( r=0.723, P<0.001)and Lp-PLA2( r=0.714, P<0.001), and Aβ1-42 was positively correlated with Lp-PLA2( r=0.698, P<0.001)in VD patients.The cut-off value, sensitivity, specificity, and area under the curve of serum sTREM2 for differentiating VD from non-VD were 3.96 μg/L, 81.30%, 78.40%, and 0.838, respectively. Conclusions:Serum sTREM2 is abnormally elevated in VD patients, and is significantly correlated with Aβ1-42 and LP-PLA2, thus STREM2 may be an indicator in the differential diagnosis of VD and non-VD.

ABSTRACT
Objective:To investigate the risk factors for 90 d death after endovascular mechanical thrombectomy (MT) in patients with acute anterior circulation large-artery occlusive stroke.Methods:From October 2015 to March 2018, patients with acute anterior circulation large-artery occlusive stroke treated with MT in People's Hospital of Shanghai Pudong New Area and the Second Affiliated Hospital of Soochow University were enrolled retrospectively. The primary outcome events were defined as death within 90 d after operation. Univariate and multivariate logistic regression models were used to identify the independent risk factors for death within 90 d after operation. Results:A total of 116 patients were enrolled, 23 (19.8%) of them died within 90 d after operation. Univariate analysis showed that there were significant differences in age, baseline National Institutes of Health Stroke Scale (NIHSS) score, the Alberta Stroke Program Early CT Score (ASPECTS), and the proportion of the baseline NIHSS score classification (≤8, 9-15, ≥16), ASPECTS ≤7, the number of attempts to pass >3 times, modified Thrombolysis in Cerebral Infarction (mTICI) blood flow grade 2b/3, hemorrhagic transformation (HT), and symptomatic HT in the death group compared with the survival group (all P<0.05). Multivariate analysis showed that after adjusting for age, fasting blood glucose, baseline NIHSS score, number of attempts to pass >3, and mTICI grade 2b/3, lower ASPECTS (odds ratio [ OR] 0.647, 95% confidence interval [ CI] 0.456-0.917; P=0.014), longer time from onset to vascular recanalization ( OR 1.004, 95% CI 1.000-1.007; P=0.046) and symptomatic HT ( OR 13.522, 95% CI 2.719-67.258; P=0.001) were the independent predictors of death within 90 d. Conclusion:The ASPECTS, time from onset to recanalization, and symptomatic HT were the independent risk factors for death within 90 d after MT in patients with acute anterior circulation large-artery occlusive stroke.
ABSTRACT
Objective To comparatively analyze the safety and efficacy of direct mechanical thrombectomy and bridging therapy for patients with acute anterior circulation large-artery occlusive stroke.Methods A total of 116 patients with acute anterior circulation large-artery occlusive stroke,admitted to our hospitals from October 2015 to March 2018,were chosen in our study;their clinical data were analyzed retrospectively.Among them,63 patients accepted direct mechanical thrombectomy and 53 accepted bridging therapy.The preoperative baseline data and the diagnoses and treatments of the two groups were analyzed;the degrees of modified thrombolysis in cerebral infarction (mTICI),incidences of hemorrhage transformation and symptomatic intracranial hemorrhage,and modified Rankin scale (mRS) scores and mortality rate 90 d after operation were compared between the two groups.Results The preoperative Alberta stroke program early CT scale (ASPECTS) and Glasgow Coma Scale (GCS) scores of the direct mechanical thrombectomy group were significantly lower than those of the bridge therapy group (P<0.05),and the time from onset to admission was significantly longer than that of the bridging therapy group (P<0.05).The incidence of postoperative hemorrhage transformation in the direct mechanical thrombectomy group was significantly higher than that in the bridging therapy group (34.9% vs.17.0%,P<0.05),but there were no significant differences in the effective recanalization rate (69.8% vs.79.3%),intracranial symptomatic hemorrhage rate (15.9% vs.7.6%),favorable outcome rate (28.6% vs.35.9%) and mortality (22.2% vs.17.0%) between the two groups (P>0.05).Conclusion The clinical efficacy and safety of direct mechanical thrombectomy and bridging therapy for patients with acute anterior circulation large-artery occlusive stroke are similar.
ABSTRACT
Objective:To explore the influencing factors for intracranial hemorrhage (ICH) in patients with acute large vessel occlusion stroke (ALVOS) of anterior circulation after mechanical thrombectomy (MT).Methods:From October 2015 to March 2018, the clinical data of 116 patients with ALVOS of anterior circulation accepted MT were analyzed retrospectively in our hospitals. These patients were divided into ICH group ( n=31) and non-ICH group ( n=85) according to whether there was ICH after operation. Univariate and multivariate Logistic regression models were used to analyze the independent influencing factors for ICH after MT. Results:Univariate analysis showed that there were significant differences in preoperative Alberta Stroke Program Early CT (ASPECT) scores, baseline systolic pressure, and preoperative blood glucose level between ICH group and non-ICH group ( P<0.05). Multivariate analysis showed that after adjusting baseline Glasgow coma scale scores, preoperative ASPECT scores ( OR=0.770, 95%CI: 0.610-0.0.971, P=0.027), baseline systolic pressure ( OR=1.029, 95%CI: 1.005-1.054, P=0.017), preoperative blood glucose level ( OR=1.177, 95%CI: 1.010-1.372, P=0.036) were independent influencing factors for ICH. Conclusion:The patients with low preoperative ASPECT scores, high baseline systolic pressure, and high blood glucose are prone to have ICH after MT in patients with ALVOS of anterior circulation.

ABSTRACT
Objective The purpose of this study was to compare the self-evaluation and doctor-patient orientation between medical students and residents before the courses in different communication sections,and gave guide to different objects for their targeted teaching.Methods We set a sample made of 331 medical students and 308 residents who were trained in Clinical communication skills course in Peking Union Medical College from Oct.2009 to Oct.2013.Before the course,they were investigated by two self-assessment questionnaires.One is communication skills and occupation practice confidence;the other is doctor-patient orientation.Their result data were analyzed and handled by SPSS 17.0 software,adopting an independent samples t test.Results The order of the different aspects of doctor patient communication skills was same in two groups,gathering complete history [(4.340 ± 0.756) vs.(4.050 ± 0.707)] first,and establishing good doctor patient relationship [(4.310 ±0.740) vs.(4.030 ±0.790)],discussing a therapeutic plan with patient [(4.050 ± 0.812) vs.(3.600 ± 0.823)],informing bad news [(3.850 ± 0.897) vs.(3.260 ± 0.907)] followed.According to the self-assessment,residents were more confident than medical students in all these aspects above mentioned and establishing good doctor patient relationship.The doctorpatient orientation scale indicated that the residents group is more inclined to doctor-centric mode than the medical students group.Conclusion This study suggested that the residents is more confident in doctorpatient communication skills than medical students,while is less inclined to patient-centric mode than them.The focus of the communication teaching is similarity in the distribution of the two groups.Medical students' communication curriculum needs to take into account the limited clinical experiences,and training for residents needs to emphasize the capacity of empathy and perspective-taking.
ABSTRACT
Objective@#To evaluate the effect of zinc ions on human umbilical vein endothelial cells biological functions.@*Methods@#The primary human umbilical vein endothelial cells were cultured with the ECM medium, and cells were divided into 8 groups: the control group(routine culture,n=3), 20 μmol/L zinc group(20 μmol/L zinc chloride solution was added into the cell medium, n=3), 40 μmol/L zinc group(40 μmol/L zinc chloride solution was added into the cell medium, n=3),80 μmol/L zinc group(80 μmol/L zinc chloride solution was added into the cell medium, n=3), 100 μmol/L zinc group(100 μmol/L zinc chloride solution was added into the cell medium, n=3), 200 μmol/L zinc group(200 μmol/L zinc chloride solution was added into the cell medium, n=3),300 μmol/L zinc group(300 μmol/L zinc chloride solution was added into the cell medium, n=3), 500 μmol/L zinc group(500 μmol/L zinc chloride solution was added into the cell medium, n=3). The cell proliferation curve was derived from real time cell analysis (RTCA). The viability value was obtained via CCK-8 reagent, and the migration distance was tested by scratch-wound assay while the adhesion function was detected by RTCA.@*Results@#(1)After 18 hours, RTCA showed that the proliferation cell indexes were 4.5±0.6, 3.7±0.4, 3.6±0.3, 2.5±0.4, and 2.5±0.4 in the 20, 40, 80, 100, and 200 μmol/L zinc groups, as compared with 3.5±0.3 in the control group (all P<0.05). Proliferation cell indexes were 0 in both of the 300 μmol/L and 500 μmol/L zinc groups. (2)After 96 hours, the viability were 1.21±0.05, 1.10±0.03, 0.99±0.05, 0.62±0.02, 0.45±0.04, 0.11±0.01, and 0.12±0.06, respectively in the 20, 40, 80, 100, 200, 300, and 500 μmol/L zinc groups, as compared with 0.75±0.05 in the control group (all P<0.05). (3)After 12 hours, the migration distances were (0.56±0.11),(0.96±0.07),(0.49±0.02), and (0.29±0.01)mm in the 20, 40, 80, and 100 μmol/L zinc groups, as compared with (0.24±0.04)mm in the control group (all P<0.05). (4)After 18 hours, the adhesion cell index were 0.40±0.05, 0.31±0.01, 0.38±0.05, and 0.40±0.03 in the 20, 40, 80, and 100 μmol/L zinc groups, as compared with 0.24±0.04 in the control group (all P>0.05).@*Conclusions@#Zinc ions at lower concentration (≤80 μmol/L) can promote proliferation, viability and migration of human umbilical vein endothelial cells, but the adhesion function was not significantly affected by zinc ions. Zinc ions at higher concentration (≥200 μmol/L) can inhibit the cellular function of the human umbilical vein endothelial cells.

ABSTRACT
<p><b>OBJECTIVE</b>Augmentation rhinoplasty is a commonly procedure in clinical work for a plastic surgeon. Autologous costal cartilage is widely used in aesthetic rhinoplasy because of the abundant in quality. However, the cartilage may warp, and it is not easy-handling for inexperienced plastic surgeons. We-used diced cartilage combined with thin strips as columellar struts, which can be easily shaped, and reduce the warping incidence.</p><p><b>METHODS</b>From July 2012 to March 2014, 61 patients were performed diced costal cartilage for nasal augmentation via endonasal approach. Standardized photographs are obtained before and after surgery. Postoperative outcome is graded by patient's self-evaluation of the nasal appearance with a satisfaction scale.</p><p><b>RESULTS</b>Among the 61 cases, 25 were revision cases. The follow-up time was no less than 6 months, with an average time of 10.9 months. 28 patients reported improved or better nasal appearance. One patient required revision surgery because of overcorrection. Supratip step-off was observed in one patient and corrected by external reshaping. No warping, infection, irregularity, absorption, airway obstruction, or donor-site morbidity were observed. All patients were satisfied with the final appearance.</p><p><b>CONCLUSIONS</b>Diced costal cartilage is a reliable option for nasal augmentation and revision rhinoplasty. Good outcomes can be achieved postoperatively, with aesthetically pleasing appearance and simple procedure.</p>

Objective:To explore diagnostic value of soluble tumor necrosis factor - like weak inducer of apoptosis (sTWEAK) and interleukin (IL) -6 concentrations in patients with acute coronary syndrome (ACS) .Methods:A total of 170 ACS patients hospitalized in our hospital from Jan 1st ,2014 to Jun 31st ,2014 were selected as ACS group ,mean‐while ,80 inpatients with stable angina pectoris (SAP) confirmed by coronary angiography (CAG) or coronary CT were se‐lected as SAP group ,and another 80 patients excluded for coronary heart disease (CHD) by CAG were regarded as normal control group .ACS group was further divided into ST elevation myocardial infarction (STEMI) group (n=45) ,non -STEMI (NSTEMI) group (n=52) and unstable angina pectoris (UAP) group (n=73) .Plasma sTWEAK and serum IL‐6 concentrations were compared among all groups .Results:Compared with normal control group and SAP group ,there were significant rise in concentrations of plasma sTWEAK [ (120.32 ± 10.15) ng/L vs .(123.86 ± 15.23) ng/L vs .(140.05 ± 17.51) ng/L] and serum IL‐6 [ (110.34 ± 26.01) pg/ml vs .(112.38 ± 25.74) pg/ml vs .(245.23 ± 68.58) pg/ml] (P0.05. There were no significant difference in plasma sTWEAK and serum IL‐6 concentrations among UAP group ,NSTEMI group and STEMI group , P>0.05 all .Conclusion:Plasma sTWEAK and serum IL‐6 concentrations significantly rise in ACS patients ,which possesses certain diagnostic value for ACS .
ABSTRACT
Objective:To measure serum levels of salusins and catestatin and analyze their correlation in patients with essential hypertension (EH) .Methods :A total of 90 EH patients were selected as hypertension group .According to blood pressure level ,they were further divided into hypertension stage 1 group (n=31) ,hypertension stage 2 group (n=30) and hypertension stage 3 group (n=29) .Another 40 normotensive subjects undergoing physical examina‐tion were selected as normal control group .Enzyme linked immunosorbent assay (ELISA) was used to measure ser‐um levels of salusins and catestatin , and the correlation between serum levels of salusins and catestatin was analyzed . Results :Compared with normal control group ,there were significant reductions in serum levels of salusins [ (3.01 ± 0.66) ng/ml vs .(1.44 ± 0.42) ng/ml ,(1.35 ± 0.89) ng/ml ,(1.41 ± 0.32) ng/ml] and catestatin [(132.24 ± 7.55) ng/ml vs .(89.22 ± 6.12) ng/ml vs .(82.51 ± 8.37) ng/ml ,(83.34 ± 4.47) ng/ml] in hypertension stage 1 ,stage 2 and stage 3 group , P0.05 all) .Pearson correlation analysis indicated that serum salusins level had no correlation with catestatin level ( r=0.363 , P>0.05) in normal control group ,while serum salusins level was significant positively correlated with catestatin level (r=0.723 ,P<0.01) in hypertension group .Conclusion:Serum levels of salusins and catestatin significantly reduce and they is positive correlation in patients with hyperten‐sion .Along with blood pressure level rises ,serum catestatin level reduces .
