ABSTRACT

The study was a retrospective study. The clinical data of 866 patients with IgA nephropathy (IgAN) in Beijing Anzhen Hospital, Capital Medical University from March 2010 to March 2021 were analyzed, to investigate the clinical pathology and renal prognosis of IgAN patients with intrarenal arteriolosclerosis, and to preliminarily explore whether abnormal activation of complement system is involved in the injury of arteriolosclerosis. The patients were divided into renal arteriolar lesions group and non-renal arteriolar lesions group according to the renal histopathology, and the differences of clinical pathological manifestations, prognosis between the two groups were compared. The results showed that, compared with the non-renal arteriolar lesions group ( n=236), IgAN patients in the renal arteriolar lesions group ( n=630) had higher proportions of hypertension and malignant hypertension, higher levels of urinary albumin-creatinine ratio, 24-hour urine protein quantification and serum uric acid, lower estimated glomerular filtration rate, and more severe MEST-C lesions of the Oxford classification (all P < 0.05). Cox regression analysis results showed that intrarenal arteriolosclerosis was the independent risk factor affecting the progression of IgAN to ESRD ( HR=6.437, 95% CI 2.013-20.585, P=0.002). Renal histopathology showed that the deposition of complement C3c on the wall of intrarenal arterioles in the renal arteriolar lesions group ( n=98) was stronger than that in non-renal arteriolar lesions group ( n=18, P < 0.05). IgAN patients with renal arteriolosclerosis present with serious clinical and pathological manifestations, and renal prognosis. Abnormal activation of complement system may be involved in the pathogenesis of intrarenal arteriolosclerosis.

ABSTRACT

Objective:To investigate the influencing factors of non-remission of proteinuria in patients with nephrotic syndrome (NS) and idiopathic membranous nephropathy (IMN).Methods:The study was a retrospective observational study. The clinical data of patients with NS who were diagnosed as IMN by renal biopsy and serum albumin recovered normal after six months of treatment were collected from Beijing Anzhen Hospital, Capital Medical University from June 1, 2010 to January 31, 2022. Patients were divided into proteinuria remission group and non-proteinuria remission group according to whether urinary protein < 3.5 g/24 h and decreased 50% from the onset. The differences of clinical and pathological characteristics between the two groups at baseline were compared. The logistic regression model was used to analyze the influencing factors of non-remission of proteinuria.Results:Ninety-five NS patients with renal pathology of IMN were included in this study, with age of 57(43, 65) years old and 50 males (52.6%). There were 75 patients in the proteinuria remission group and 20 patients in the non-proteinuria remission group. Compared with the proteinuria remission group, the non-proteinuria remission group had higher baseline body mass index [(26.83±4.03) kg/m 2vs. (24.68±3.97) m 2, t=-2.149, P=0.034] and proportion of overweight (85.0% vs. 58.7%, χ2=4.765, P=0.029), and larger waist circumference [88.5(85.3, 101.5) cm vs. 87.0(77.5, 92.0) cm, Z=2.362, P=0.018]. Renal pathological results showed that the proportions of diabetes nephropathy (10.0% vs. 0, P=0.043) and glomerular hypertrophy (45.0% vs. 20.0%, χ2=5.227, P=0.022) were higher, and the average diameter of hypertrophic glomeruli was longer [(197.96±6.37) μm vs. (193.51±8.50) μm, t=2.029, P=0.041] in the proteinuria remission group than those in the non-proteinuria remission group. Multivariate logistic regression analysis results showed that waist circumference was an independent influencing factor of non-proteinuria remission in patients with IMN under waist circumference > 90 cm in men and >85 cm in women ( OR=1.083, 95% CI 1.005-1.168, P=0.037). Conclusion:Abdominal obesity is an independent risk factor of non-remission of proteinuria in NS patients with IMN after early treatment.

ABSTRACT

OBJECTIVE To establish the methods to identify the chemical components of Ixeris chinensis, and determine the contents of 7 components (chlorogenic acid, luteolin, quercetin, rutin, protocatechuic acid, isochlorogenic acid A, luteoloside). METHODS HPLC-Q-Exactive-MS was used to identify the chemical components of I. chinensis. The contents of 7 components in I. chinensis, including chlorogenic acid, were determined by HPLC-MS/MS. RESULTS A total of 45 components were identified in I. chinensis, including 20 organic acids, 13 flavonoids, 4 fatty acids, 4 amino acids, 3 nucleosides, and 1 coumarin. The linear range of chlorogenic acid, luteolin, quercetin, rutin, protocatechuic acid, isochlorogenic acid A and luteoloside were 503.00- 25 150.00, 42.00-2 100.00, 5.05-252.50, 20.05-1 002.50, 25.10-1 255.00, 750.00-37 500.00, 196.00-9 800.00 ng/mL (r≥0.999 2), respectively. RSDs of precision, stability and reproducibility tests were all less than 3.00% (n=6), and average recovery ranged from 96.72% to 105.84% (all RSD<4.00%, n=6). The contents of 7 components in 3 batches of I. chinensis were 1 145.77- 3 261.25, 23.75-97.90, 0.92-2.12, 1.06-23.18, 9.35-21.85, 833.25-1 045.58, 199.56-1 869.78 μg/g, respectively. CONCLUSIONS The established methods for identification and content determination are rapid and simple, and can be used for the identification of chemical components and the content determination of 7 components in I. chinensis.

ABSTRACT

Objective:To investigate the role of complement activation in the pathogenesis of primary malignant hypertension (MHT) with nephrosclerosis complicated with severe cardiorenal injury.Methods:Data of MHT patients with nephrosclerosis proven by biopsy from January 2010 to December 2020 in the Beijing Anzhen Hospital, Capital Medical University were retrospectively analyzed. The expressions of complement-related component C4d, C1q, complement factor H-related protein 5, C3c and C5b-9 were detected by immunohistochemical staining. According to whether the patients were complicated with acute heart failure (AHF) and/or acute kidney injury (AKI), they were divided into severe cardiorenal injury group and non-severe cardiorenal injury group. The differences of clinicopathological data between the two groups were compared. According to the degree of C4d deposition in renal tissues, patients were divided into C4d diffused deposition group and non-C4d diffused deposition group. The severity of cardiorenal injury and the pathological characteristics of thrombotic microangiopathy in renal tissues were compared between the two groups.Results:A total of 33 patients were enrolled in this study, of which 17 cases (51.5%) were complicated with severe cardiorenal injury; AHF occurred in 16 patients (48.5%), AKI occurred in 8 patients (26.7%), and AHF and AKI were combined in 7 patients (21.2%). Compared with non-severe cardiorenal injury group, patients in severe cardiorenal injury group had higher levels of baseline lactate dehydrogenase [326.0 (217.0, 366.0) IU/L vs 197.0 (165.0, 220.0) IU/L, Z=37.000, P=0.002] and hemoglobin [(143.6±24.0) g/L vs (106.4±24.7) g/L, t=38.500, P<0.001], lower levels of 12 h urinary incontinence osmolality [400.0 (342.5, 504.0) mmol/L vs 476.0 (432.3, 616.5) mmol/L, Z=72.000, P=0.021] and serum albumin [(36.2±9.4) g/L vs (43.2±6.2) g/L, t=6.423, P=0.017], and thicker left ventricular posterior wall [(14.0±2.1) mm vs (12.1±1.1) mm, t=6.552, P=0.018]. The immunohistochemical results of kidney tissue showed that the proportions of C4d and C5b-9 diffused deposition in severe cardiorenal injury group were significantly higher than those in non-severe cardiorenal injury group (5/16 vs 0/15, P=0.043; 12/16 vs 5/15, P=0.032). Compared with non-C4d diffused deposition group, C4d diffused deposition group had higher incidence of AHF (5/5 vs 10/26, P=0.018), poorer heart function, more severe ventricular remodeling, and shorter history of hypertension [2.0 (0, 12.0) months vs 48.0 (9.5, 84.0) months, Z=22.500, P=0.022]. Conclusions:The incidence of severe cardiorenal injury in MHT patients with nephrosclerosis is about 51.5%. The proportion of diffuse deposition of complement activated components in renal tissues in patients with severe cardiorenal injury is higher than that in patients with non-severe cardiorenal injury. Overactivation of complement may be involved in the pathogenic process of severe heart and kidney injury caused by MHT.

ABSTRACT

Objective:To investigate the intention to obtain disease related information and its influencing factors among the elderly at their end-of-life stage.Methods:A cross-sectional survey was conducted among 414 elderly people aged ≥60 in 7 long-term residential care facilities and 15 communities in the central urban area of Fuzhou using the late-life care preference questionnaire from October 2016 to June 2017. Univariate analysis, multiple linear regression analysis and ordered multi-classification logistic regression analysis were used to identify information preference of the disease-related information and influencing factors among the elderly.Results:The level of disease-related information needs of the elderly was scored (17.1±4.9); 48.8% (202/414) preferred detailed or maximum information; 30.7% (127/414) wanted selective and partial information; 20.5% (85/414) did not want to know any information. Multiple linear regression analysis showed that age, education, and whether or not they had received or seen other life-sustaining treatments were the main factors affecting the level of disease-related information needs (standardized regression coefficients were -0.141, 0.116, 0.115, all P<0.05); ordered multi-classification logistic regression analysis showed that age (compared with 60-69 years old, 70-79 years old: OR=0.544, 95% CI: 0.310-0.957; 80-89 years old: OR=0.526, 95% CI: 0.289-0.956), education level (compared with primary school and below, college or above: OR=2.166, 95% CI: 1.093-4.290), main sources of living expenses (compared with other allowance, family support: OR=7.303, 95% CI: 1.157-46.108, pension: OR=9.288, 95% CI: 1.502-57.415; provident fund scheme/saving: OR=15.676, 95% CI: 2.122-115.793), whether or not they had received or seen other life-sustaining treatments (compared with yes, OR=1.985, 95% CI: 1.150-3.425) were the main factors affecting the level of disease-related information needs. Conclusions:Most of the elderly prefer to know disease-related information. Age, educational level, main sources of living expenses and whether or not they had received or seen other life-sustaining treatments are the main influencing factors.

ABSTRACT

Objective:To evaluate the efficacy and tolerability of the dual therapy of dolutegravir (DTG) plus lamivudine (3TC) as a switch simplified strategy in treatment-experienced human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) patients.Methods:Treatment-experienced HIV/AIDS patients who switched to a dual therapy containing DTG (50 mg, once daily) plus 3TC (300 mg, once daily) were included in Beijing You′an Hospital, Capital Medical University from September 2016 to May 2019. HIV RNA, CD4 + T lymphocyte count, blood lipid indexes, renal function indexes were collected when patients changed the treatment regimen (baseline) and after 48 weeks of treatment. Efficacy (HIV RNA<50 copies/mL) and safety of the dual therapy were analyzed. Statistical comparisons were performed using the Wilcoxon matched-pairs signed rank test. Results:The reasons for 33 patients switching the treatment regimen were virologic failure (four cases, 12.1%), simplification of regimen (11 cases, 33.3%), and drug toxicity (18 cases, 54.5%). The patients were treated with anti-retroviral therapy (ART) for 2.13 (1.05, 4.23) years before regimens switching. Twenty-nine (87.9%) patients were virologically suppressed at baseline, and four (12.1%) patients were virological failure. After switching to DTG plus 3TC, all 33 patients showed HIV RNA<50 copies/mL after 48 weeks of treatment. The baseline CD4 + T lymphocyte count was 543 (363, 595)/μL. After switching the treatment regimens for 48 weeks, CD4 + T lymphocyte count was significantly increased to 625 (455, 651)/μL, and the difference was statistically significant ( Z=3.14, P=0.002). Compared with baseline, low-density lipoprotein-cholesterol was increased after 48 weeks of treatment (2.35(1.80, 3.08) mmol/L vs 3.12(2.74, 3.87) mmol/L), while triglyceride (2.21(1.27, 4.37) mmol/L vs 1.61(1.20, 2.22) mmol/L), the ratio of total cholesterol to high-density lipoprotein-cholesterol (5.02 (4.13, 6.40) vs 4.70 (3.55, 5.35)) and estimated glomerular filtration rate (106.4(78.2, 118.2) mL/(min·1.73 m 2) vs 88.6 (75.7, 107.9) mL/(min·1.73 m 2)) were decreased. The differences were all statistically significant ( Z=4.89, 2.37, 2.09 and 2.83, respectively, all P<0.050). No patient discontinued due to adverse events. Conclusions:The use of dual therapy containing DTG and 3TC is effective and well-tolerated in treatment-experienced HIV/AIDS patients under any prior ART without significant adverse events.

ABSTRACT

OBJECTIVE: To screen the hepatoprotective active fractions from Ixeris chinensis and study its chemical constituents. METHODS:The petroleum ether,ethyl acetate,n-butanol and residual water fractions from 70% ethanol extract of I.chinensis were extracted by systematic solvent method. Human hepatocytes HL-7702 were induced by acetaminophen to induce liver injury model. MTT method was used to detect the protective effect of the above fractions(40 μg/mL,by the dosage of crude drug)on injured cells,and the active fractions were screened. The active fractions were separated and purified by silica gel column and Sephadex column chromatography. The structure of the compounds were identified by physical and chemical properties and spectral data (hydrogen spectrum,carbon spectrum). RESULTS:After treated with different fractions of I. chinensis,the cell survival rate of each administration group was increased significantly,compared with model group(P<0.01),and the n-butanol and water fractions had the strongest activity (the cell survival rates were 49.3% and 52.2% ,respectively). Six compoundswere isolated from n-butanol fraction and identified as sonchifolignan A(Ⅰ),apigenin-7-O-β-D-glucopyranoside methyl ester(Ⅱ),luteolin-7-O-β-D-glucuronopyranoside methyl ester (Ⅲ),luteolin-7-O-β-D-glucopyranoside (Ⅳ),apigenin-7-O-β-Dglucopyranoside(Ⅴ)and luteolin(Ⅵ). CONCLUSIONS:The n-butanol fraction is regarded as an effective position for protecting liver,and flavonoids are the main active omponents.KEYWORDS Ixeris chinensis;Hepatoprotective activi

ABSTRACT

Acute respiratory failure due to acute hypoxemia is the major manifestation in severe coronavirus disease 2019 (COVID-19) induced by severe acute respiratory syndrome coronavirus 2 infection. Rational and effective respiratory support is crucial in the management of COVID-19 patients. High-flow nasal cannula (HFNC) has been utilized widely due to its superiority over other non-invasive respiratory support techniques. To avoid HFNC failure and intubation delay, the key issues are proper patients, timely application and improving compliance. It should be noted that elder patients are vulnerable for failed HFNC. We applied HFNC for oxygen therapy in severe and critical COVID-19 patients and summarized the following experiences. Firstly, to select the proper size of nasal catheter, to locate it at suitable place, and to confirm the nose and the upper respiratory airway unobstructed. Secondly, an initial flow of 60 L/min and 37℃ should be given immediately for patients with obvious respiratory distress or weak cough ability; otherwise, low-level support should be given first and the level gradually increased. Thirdly, to avoid hypoxia or hypoxemia, the treatment goal of HFNC should be maintained the oxygen saturation (SpO) above 95% for patients without chronic pulmonary disease. Finally, patients should wear a surgical mask during HFNC treatment to reduce the risk of virus transmission through droplets or aerosols.

ABSTRACT

Objective To investigate the current state of psychological distress of lymphoma patients'caregivers, and analyze its influencing factors. Methods From October 2017 to February 2018, 96 pairs (patients and their caregivers) from the department of lymphoma were enrolled. Distress Thermometer and self-designed general scale were adopted to conduct survey. Results The psychological distress score of lymphoma caregivers was as high as (4.76 ± 2.28) points, which was significantly higher than the patient's score (3.81±2.33) points, the difference was statistically significant (t=4.070,P<0.05 ). Different ages, economic status, and patient's disease of caregivers had different psychological distress, and the difference was statistically significant (P<0.05). Meta-linear regression analysis showed that age and patient psychological distress were the main influencing factors of psychological distress of lymphoma patients'caregivers, which could explain the variability of 32.7%(P<0.05). Conclusions The psychological distress of lymphoma patients'caregiver is at a moderate level, which is affected by their age and psychological distress of the patients. It suggests that clinical medical staff should pay attention to the psychological distress of patients and strengthen the psychological support of caregivers to better promote patient care.

ABSTRACT

Objective To evaluate the diagnostic value of pathological features of atypical membranous nephropathy (AMN). Methods Ninety - one patients with AMN diagnosed by renal biopsy during 2011 and 2017 were enrolled in this study. On the basis of M - type phospholipase A2 receptor (PLA2R) and thrombospondin type - 1 domain - containing 7A protein (THSD7A) by immunohistochemistry, patients were divided into AMN group (25 cases without PLA2R and THSD7A) and idiopathic membranous nephropathy (IMN) group (66 cases with positive PLA2R or THSD7A). The results of immunofluorescence (IF), light microscopy (LM) and electron microscopy (EM) of these two groups were compared, and the parameters with statistical difference were screened out in order to assess their value in the diagnosis of AMN in fourfold table. Results IF results showed that in AMN group the proportions of IgG deposition on capillary wall and mesangial area as well as positive otherIgG subclasses and complement C1q but negative IgG4 were significantly higher than those in IMN group (respectively, 56.0% vs 12.1% , 44.0% vs 0, both P<0.05). Their diagnostic specificities for AMN were 87.9% and 100.0%, respectively. However, the positive rates of IgG accompanied with IgA and/or IgM, predominant IgG4 with other IgG subclasses and complement C1q in two groups were not significantly different (all P>0.05). LM results showed that the proportions of false double track sign on basement membrane and fuchsinophilic proteins under epithelium, endothelium, basement membrane and mesangial region in AMN group were significantly higher than those in IMN group (respectively, 36.0% vs 0, 44.0% vs 1.5%, both P<0.05). Their diagnostic specificities for AMN were 100.0% and 98.5% , respectively. However, the scores of mesangial cell proliferation of these two groups showed no significantly difference (P>0.05). EM results showed that the rate of endothelial electron dense deposits in AMN group was significantly higher than that in IMN group (36.0% vs 1.5%, P<0.05), and its diagnostic specificity for AMN was 98.5%. Conclusions IgG deposition on both capillary wall and mesangial area, positive other IgG subclasses and C1q with negative IgG4, false -double contour sign, multi - site fuchsinophilic deposits and endothelial electron dense deposits may help for the AMN diagnosis in the absence of PLA2R and THSD7A related data.

ABSTRACT

Objective To explore the effects of high-frequency electromagnetic radiation exposure on the mood-cognitive behaviors of mice, and to provide an experimental basis for the study on radiation damage mechanism and protection. Methods The electromagnetic reverberation chamber can produce continuous and uniform high-frequency electromagnetic waves. Different groups of ICR mice were exposed to high-frequency electromagnetic radiation in this chamber for 1 d, 3 d and 7 d, and then series of behavioral tests were conducted to observe the changes in locomotor activities,depressive-like and anxiety-like behaviors, and cognitive function of the mice. Results After exposed to the high-frequency electromagnetic radiation(3 GHz,SAR 4 W/kg)4 h/d for 7 d,there was no obvious change in locomotor activity(times of grid crossing and standing up in the open field test)of the mice,while the times of entering the central region(P< 0.05)and the time duration(P< 0.05)were significantly decreased. Compared with the unexposed group, the percentage of the times of entering the open arm in the elevated-plus maze(P< 0.05)and the time duration in the open arm(P< 0.01)of the mice in the radiation group were significantly decreased. Meanwhile, the immobility time in the forced-swimming test(P< 0.01)and the tail suspension test(P < 0.05)of the mice exposed to electromagnetic radiation was significantly increased, and the discrimination index of new objects in the new object recognition test was significantly reduced(P < 0.001). Conclusions Continual exposure to high-frequency electromagnetic radiation(3 GHz,SAR 4 W/kg)can lead to anxious-depression behaviors and cognitive impairment of mice in a time-dependent manner,which provides an experimental basis for the relevant study of prevention and therapy techniques.

ABSTRACT

Objective To investigate whether the clinical and pathological injury of kidney in IgA nephropathy (IgAN) patients with hypertension is associated with circadian blood pressure rhythm change, particularly with elevated nocturnal blood pressure (BP). Methods This study was a retrospective cross-sectional study. Clinic and renal histopathological injury data were obtained from 83 IgAN patients with hypertension. First, 24 h ambulatory BP monitoring (ABPM) data were analyzed. Second, all these IgAN patients were divided into two groups, elevated nocturnal BP group and nocturnal normotensive BP group, and the clinical and pathological differences between this two groups were analyzed. Third, logistic regression analysis was used to analyze the influencing factors of renal tubulointerstitial injury in IgAN patients with hypertension. At last, all these IgAN patients were divided into two groups according to the level of estimated glomerular filtration rate (eGFR), group of patients with eGFR≥60 ml·min-1·(1.73 m2)-1 and the other group with eGFR<60 ml·min-1·(1.73 m2)-1, and the 24 h ABPM data were compared. Results (1) The proportion of non-dipper circadian rhythm of BP in IgAN patients with hypertension was 79.5%. (2) Compared with nocturnal normotensive BP group, patients in elevated nocturnal BP group had significantly higher levels of 24-hour urinary protein quantity and blood uric acid (both P<0.05), and lower eGFR and urine osmotic pressure clinically (both P<0.05). Index of interstitial fibrosis and tubular atrophy was significantly higher in nocturnal normotensive BP group (P<0.05), while the proportion of glomerular ischemia lesion was not significantly different between two groups. (3) Multivariate logistic regression analysis showed that elevated nocturnal BP was an independent risk factor for severe tubulointerstitial injury of IgAN (OR=1.113, 95%CI 1.038-1.192, P=0.002). (4) Compared with the group of eGFR≥60 ml·min-1·(1.73 m2)-1, 24-hour systolic blood pressure (SBP) and diastolic blood pressure (DBP), daytime SBP and DBP, nocturnal SBP and DBP were significantly higher in group of eGFR<60 ml·min-1·(1.73 m2)-1 (all P<0.05). Conclusion The proportion of non-dipper circadian rhythm of BP in IgAN patients with hypertension is as high as 79.5%. Elevated nocturnal BP is associated with the severity of renal damage, and elevated nocturnal BP is an independent risk factor for severe tubulointerstitial injury in IgAN patients with hypertension. Therefore, 24 h ABPM should be emphasized, and elevated nocturnal BP should be well controlled to slow the progression of IgAN.

ABSTRACT

Objective To explore the causes of nocturnal hemodialysis (NHD) patient dropout and the risk factors for dropout.Methods We collected the clinical data of patients receiving NHD for more than 3 months,of whom 47 patients dropped out and 64 kept receiving NHD from Feb.2009 to Nov.2016 in Changzheng Hospital of Second Military Medical University.We investigated the general conditions;and we compared the differences of the blood parameters between the two groups when the patients received NHD for the first time and for the last time,including hemoglobin,platelet,albumin,ferritin,serum calcium,serum phosphorus and parathyroid hormone.We also analyzed the risk factors for NHD dropout or for death using Cox regression analysis model.Results Among 111 patients,47 patients had withdrawn from NHD,with their average time for NHD being (31.55±20.30) months,and the causes for dropout included death,transferring to other hospitals,turning to conventional hemodialysis (CHD),renal transplantation and others.Univariate Cox regression analysis showed that hypertensive nephropathy (P=0.007,HR=2.913,95%CI:1.348-6.293) and diabetic nephropathy (P=0.047,HR=2.401,95%CI:1.014-5.685) were risk factors for NHD patient dropout,while chronic nephritis syndrome (P<0.001,HR=0.095,95%CI 0.046-0.195) was a protective factor;blood albumin (P=0.007,HR=0.904,95%CI:0.840-0.973) and age (P=0.027,HR=1.052,95%CI:1.006-1.101) were risk factors for NHD patient dropout.Multivariate Cox regression analysis showed that albumin level (P=0.007,HR=0.911,95%CI:0.848-0.991) was an independent risk factor for death in NHD patients.Conclusion Hypertensive nephropathy and diabetic nephropathy are the risk factors for NHD patients dropout,while chronic nephritis syndrome was a protective factor.Low serum albumin level is an independent risk faetor for death in NHD patients.

ABSTRACT

Objective To investigate the expression of CXCR4 and CXCL12 in the labial gland of patients with primary Sj?gren's syndrome (pSS), and to explore their role in the pathogenesis of pSS. Methods The expression of CXCR4 and CXCL12 in labial gland tissues was detected by immunohistochemistry in 32 cases of newly diagnosed pSS and 30 cases of oral mucosa cysts or trauma patients. The expression level, intensity and location were analyzed and compared statistically. χ2 test and Spearman correlation analysis were used for statistical analysis. Results The positive rate of CXCR4 in the test group was 91%(n=29), which was significantly higher than that in the control group (33%, n=10, χ2=21.77, P=0.001). The positive rate of CXCL12 in the test group was 97%(n=31), which was significantly higher than that in the control group 40%(n=12), and the difference was statistically significant ( χ2=23.57, P=0.001). Conclusion CXCR4 and CXCL12 are highly expressed in labial gland of pSS patients, this suggests that they participate in the pathological process of pSS local inflammatory response and play an important role in pSS pathogenesis.

ABSTRACT

Objective To investigate whether Helicobacter pylori (H.pylori) infection correlated with primary infertility,whether H.pylori infection caused the abnormal elevation of pro-inflammatory cytokines in primary infertility women,and whether cytotoxin associated gene A (CagA) protein played a key role in it.Methods From September 2015 to August 2016,213 patients with primary infertility (infertility group) and 97 healthy individuals (control group) were selected.According to the common etiologies,patients with primary infertility were divided into groups with single-factor infertility,multifactorial infertility and unexplained reason groups.Serum H.pylori IgG antibody and CagA antibody were examined by H.pylori antibody type test kits.The levels of interleukin (IL)-2,IL-4,IL-5,IL-6,IL-8,IL-10,IL-13,IL-18,IL-1β,granulocyte-macrophage-colony stimulating factor (GM-CSF),interferon-γ (IFN-γ),tumor necrosis factor-a (TNF-a) and IL-12p70 were tested by ProcartaPlex Immunoassays.Chi square test and independent sample t test were performed for statistical analysis and risk was assessed.Results The positive rate of serum H.pylori IgG antibody of patients with primary infertility was higher than that of healthy control group (74.0%,37/50 vs 56.7%,55/97),and the difference was statistically significant (odds ratio (OR) =2.173,95 % confidence interval (CI) 1.028 to 4.595,x2=4.216,P =0.040).There was no statistically significant difference in the positive rate of CagA antibody between primary infertility group and healthy control group (71.7 %,91/127 vs 74.5 %,41/55,OR=0.863,95%CI0.421 to1.772,P>0.05).The serum levels ofIL-8,IL-18 andIFN-γ of H.pylori positive primary infertility patients were (35.14 ± 12.16),(11.83 ± 4.01) and (11.05 ±3.17) ng/L,respectively,which were all higher than those of H.pylori positive healthy control group ((21.44±12.35),(9.89±2.23) and (8.90±1.45) ng/L,respectively) and H.pylori negative primary infertility group ((11.45±8.63),(7.90±0.99) and (8.18±1.10) ng/L,respectively),and the differences were statistically significant (t=6.947,3.366 and 4.811;15.596,8.900 and 8.068;all P<0.05).The levels of IL-8,IL-18 and IFN-γ of H.pylori positive unexplained reason primary infertility group were (39.97 ± 11.52),(13.12±4.61) and (13.06±3.70) ng/L,respectively,which were all significantly higher than those of single-factor infertility group ((31.65 ±11.20),(11.12 ± 3.46) and (10.14 ± 2.41) ng/L,respectively) and multifactorial infertility group ((30.47±8.49),(11.13±3.79) and (10.07±2.50) ng/L,respectively);and the differences were statistically significant (t=4.217,2.942 and 5.738;5.138,2.562 and 5.218;all P<0.05).In H.pylori positive primary infertility group,the levels of IL-8,IL-18 and IFN-γ of CagA positive patients were (40.42 ± 13.80),(13.04 ± 4.19) and (11.51± 3.41) ng/L,respectively,which were all significantly higher than those of CagA negative patients ((23.49 ± 11.57),(9.08 ± 1.43) and (10.04 ± 2.29) ng/L,respectively) and CagA positive individuals in healthy control group ((21.85 ± 12.14),(10.20 ± 2.29) and (9.31 ± 2.38) ng/L,respectively);and the differences were statistically significant (t =6.507,5.533 and 2.380;7.417,4.069 and 3.738;all P<0.05).Conclusion CagA positive H.pylori infection can increase the level of serum pro-inflammatory cytokines,which may be a risk factor of primary infertility.To patients with unexplained primary infertility,this may be the cause of infertility.

ABSTRACT

Objective To discuss the adjustment effects of kidney reinforcing medicine on growth and development and the content of choline acetyl transferase (CHAc) in rats with kidney-deficiency constitution. Methods The method of cats scare rats was used to build composite offspring rat models with deficiency and acquired dystrophy, and then the models were divided into model group, Zuogui Pill group and Yougui Pill group. The rats in blank group came from normal pregnant rats. Baby rats were scared and received gavage at the same time. All administration groups received suspension of Zuigui Pills or Yougui Pills. Blank group and model group received the same amount of normal saline, once a day, for 3 months. Growth and development of rats were observed. Weight and food utilization of rats aged 5–8 weeks in each group were recorded. The content of brain CHAc was detected by ELISA. Results When offspring were 5–8 weeks old, weights of rats in the model group were lower than blank group (P<0.01); while weights of rats in Zuogui Pill group and Yougui Pill group increased significantly (P<0.05) and the food utilization was positively correlated with weight; the CHAc content in the model group decreased significantly compared with blank group (P<0.05, P<0.01); while the CHAc content in Zuogui Pill group and Yougui Pill group increased significantly compared with the model group (P<0.01). Conclusion Kidney reinforcing medicine can improve backward growth and development of rats with kidney-deficiency constitution and adjust CHAc in the brain, so as to promote the learning and memory ability of rats with kidney-deficiency constitution.
