Traditional Chinese Medicine Syndrome of Primary Sjögren's Syndrome Patients with Interstitial Lung Disease / 中国实验方剂学杂志

ObjectiveTo summarize the characteristics of traditional Chinese medicine （TCM） syndrome in primary Sjögren's syndrome （pSS） patients with interstitial lung disease （ILD） and to explore associated factors. MethodA survey was conducted and pSS patients who were treated in TCM department of rheumatism at China-Japan Friendship Hospital from December 2018 to April 2022 were included. Tongue manifestations and syndromes of patients were recorded. pSS patients with ILD were classified into the pSS-ILD group and those without the ILD were included in the pSS-non-ILD group. The tongue manifestations， syndromes， and laboratory indexes were compared between the two groups， and logistic regression was used to explore the factors associated with pSS-ILD. ResultA total of 200 pSS patients were included， with 186 （93.0%） females， median age of 57 years， and median disease course of 60 months， of which 44 （22%） had pSS-ILD. In terms of tongue manifestations， pSS-ILD patients generally had dark/purple/stasis tongue， fissured tongue， and tongue with little fluid， thick coating， yellow coating， and greasy coating. The proportion patients with yellow coating was higher in pSS-ILD group than in the pSS-non-ILD group （χ2=4.799，P<0.05）. In terms of syndrome， more than 40% of pSS-ILD patients had Qi deficiency， Yin deficiency， phlegm-dampness， Qi stagnation， and/or blood stasis syndrome. As for Yin deficiency， liver-kidney Yin deficiency syndrome ranked the first. For Qi deficiency， lung Qi deficiency syndrome was most commonly seen. The proportion of patients with lung Qi deficiency was higher in the pSS-ILD group than in the pSS-non-ILD group （χ2=18.667，P<0.01）. As to laboratory indexes， compared with the pSS-non-ILD group， pSS-ILD group had high proportion of anti-SSA-positive patients （P<0.05） and high levels of C-reactive protein （CRP） （P<0.01）， complement C3 （χ2=4.332，P<0.05）， and complement C4 （P<0.05）. Logistic regression analysis showed that pSS with ILD was positively associated with lung Qi deficiency ［odds ratio （OR）=6.079， 95% confidence interval （CI） 2.585-14.298， P<0.01）］ and yellow coating （OR=5.260， 95% CI 1.337-20.692， P<0.05） and negatively associated with low C4 （OR=0.199， 95% CI 0.070-0.564， P<0.01）. ConclusionAbout 22% of pSS patients had ILD， and patients with pSS-ILD generally have Qi deficiency， Yin deficiency， phlegm-dampness， Qi stagnation， and/or blood stasis syndrome. Yellow coating， lung Qi deficiency and C4 level are factors associated with pSS combined with ILD.

Clinical Characteristics of Geographic Tongue in Patients with Primary Sjögren's Syndrome / 中国实验方剂学杂志

ObjectiveTo analyze the clinical characteristics of geographic tongue in patients with primary Sjögren's syndrome （pSS）. MethodPatients with pSS treated in the China-Japan Friendship Hospital from December 2018 to October 2021 were enrolled and divided into different groups according to the presence of geographic tongue or the severity. Phi correlation analysis，Chi-square test， and Mann-Whitney test were used to analyze the clinical characteristics of patients with geographic tongue. ResultA total of 182 pSS patients were included in this study，including 75 （41.2%） patients with geographic tongue and 107 （58.8%） without geographic tongue. Partial exfoliation was more common than total exfoliation， and the anterior part of the tongue was the most common exfoliation site. The number of patients with severe geographic tongue was more than those with mild-to-moderate geographic tongue. Compared with pSS patients without geographic tongue，those with geographic tongue were more common in fissured tongue （92.0%/41.1%，χ2=48.491，P<0.05），red or crimson tongue （48.0%/23.3%，χ2=12.009，P<0.05），Yin deficiency syndrome （100.0%/43.9%，χ2=62.739，P<0.05），and Qi deficiency syndrome （94.7%∶50.5%，χ2=40.046，P<0.05），less common in phlegm-dampness syndrome （33.3%/72.0%，χ2=26.709，P<0.05），and showed higher proportions in hyperglobulinemia （89.3%/65.4%，χ2=13.547，P<0.01），ANA ≥1∶160 （78.1%/57.3%，χ2=8.227，P<0.01），and positive RF （51.4%/36.5%，χ2=3.877，P<0.05）. Compared with pSS patients with mild geographic tongue，pSS patients with moderate-to-severe geographic tongue had higher proportions in hyperglobulinemia （98.1%/68.2%，χ2=14.617，P<0.01），positive anti-CENP-B （26.0%/4.8%，χ2=4.214，P<0.05），and reduced complement 3 （26.4%/4.5%，χ2=4.647，P<0.05）. The geographic tongue was positively associated with fissured tongue （φ=0.531），Yin deficiency syndrome （φ=0.587），and Qi deficiency syndrome （φ=0.469），negatively associated with phlegm-dampness syndrome （φ=-0.447），and weakly associated with tongue color （φ<0.4）. There was no statistical difference in the disease activity index between patients with or without geographic tongue and severity. ConclusionMore than 40% of pSS patients had geographic tongue accompanied by fissured tongue. Geographic tongue is positively associated with Yin deficiency syndrome and Qi deficiency syndrome，and negatively associated with phlegm-dampness syndrome， indicating that treatment should be based on tonifying Qi and nourishing Yin. Compared with pSS patients without geographic tongue， those with geographic tongue may have higher positive rate of some immune indicators，which deserves further exploration.

Characteristics of Tongue Manifestations and Syndromes of Patients with Primary Sjögren's Syndrome of Different Time / 中国实验方剂学杂志

ObjectiveTo explore the characteristics of tongue manifestations and traditional Chinese medicine （TCM） syndromes in patients with primary Sjogren's syndrome （pSS） of different time. MethodpSS patients who visited TCM Department of Rheumatism in China-Japan Friendship Hospital from December 2018 to October 2021 were included and grouped according to the disease courses （short<5 years， medium 5-10 years， long > 10 years）. Chi-square test was used for comparison between three groups and Bonferroni method for multiple comparisons. In the pairwise comparison， P<0.017 indicated significant difference. Chi-square test was performed on the syndrome and specific tongue manifestations with inter-group differences to analyze the trend of tongue manifestations and TCM syndromes over time （interval： two years）. ResultA total of 193 pSS patients were enrolled， with 85 （44.0%） of short disease course， 69 （35.8%） of medium disease course， and 39 （20.2%） of long disease course. The common tongue manifestations were crimson tongue， fissured tongue， thin tongue， lack of fluid， and dry coating， which showed no significant difference among the three groups. Higher proportion of patients with light red tongue was observed in the group with short disease course than in group with medium disease course （χ2=6.407， P<0.017）. Higher proportions of patients with thick coating （χ2=6.784， P<0.017） and phlegm-dampness syndrome （χ2=11.545， P<0.017） and lower proportion of patients with Qi deficiency syndrome （χ2=12.706， P<0.017） were found in the group with short disease course than in the group with long disease course. Patients with medium （χ2=6.358， P<0.017） and long （χ2=8.279， P<0.017） disease course tended to have exfoliated coating compared with those with short disease course， and the proportion of patients with exfoliated coating rose and the proportion of patients with thick greasy coating decreased over time （Ptrend<0.05）. In addition， the proportion of patients with phlegm-dampness syndrome decreased and that with Qi deficiency syndrome increased over time （Ptrend<0.05）. ConclusionIn the early stage， patients with pSS often show both dryness and dampness， as manifested by the thick greasy coating and phlegm-dampness syndrome. In the medium and late stage， patients often have Qi-Yin deficiency， as evidenced by exfoliated coating and Qi deficiency. In the clinical practice， medicines should be prescribed based on tongue manifestations and TCM syndrome of patients.

Effect of Huashi Runzao Prescription on Primary Sjögren's Syndrome / 中国实验方剂学杂志

ObjectiveTo observe the efficacy and safety of Huashi Runzao prescription for patients with primary Sjögren's syndrome （pSS） of combined dryness and dampness pattern. MethodA total of 105 eligible patients were randomized into the experimental group （65 cases） and control group （40 cases）， and they were respectively treated with Huashi Runzao prescription and hydroxychloroquine for 12 weeks. Visual Analogue Scale （VAS） was employed to assess the symptoms. The symptoms of dryness， fatigue， and pain， European League Against Rheumatism （EULAR） Sjögren's Syndrome Patient Reported Index （ESSPRI）， EULAR Sjögren's syndrome disease activity index （ESSDAI）， and immune inflammatory indicators before and after treatment were compared between the two groups， and adverse reactions were observed. ResultAfter treatment， the ESSPRI score was lower than that before treatment in the experimental groups （P<0.01） and was lower in the experimental group than in the control group （P<0.05）. The VAS scores of dry mouth， dry eyes， overall dryness， fatigue， and pain in the experimental group decreased compared with those before treatment （P<0.01）， and the experimental group had lower VAS scores of dry mouth and overall dryness than the control group （P<0.01）. After treatment， the ESSDAI score of both groups decreased compared with that before treatment （P<0.05， P<0.01）， but there was no significant difference between the groups. After treatment， the level of immunoglobulin M （IgM） decreased （P<0.01） and the level of complement C3 increased （P<0.01） in the experimental group， while the level of complement C3 decreased in the control group （P<0.05）. There was no significant difference in the laboratory indexes between groups. During the treatment， stomachache occurred to one case in the experimental group， which was alleviated after the treatment， and no adverse reaction was observed in the control group. According to the chi-square test， the occurrence of adverse reactions was insignificantly different between the two groups. ConclusionHuashi Runzao prescription can alleviate the symptoms of dryness， fatigue， and pain， and reduce disease activity without associated side effects in pSS patients with combined dampness and dryness pattern.

Effect of Huashi Runzao Prescription on Structure and Function of Submandibular Gland in Sjögren's Syndrome Model Mice / 中国实验方剂学杂志

ObjectiveTo investigate the effects of Huashi Runzao prescription （HRP） on the histopathological injury and function of submandibular gland in naive non-obese diabetic （NOD/Ltj） mouse model of Sjögren's syndrome （SS） and its regulatory effect on aquaporin 5 （AQP5） expression in submandibular gland cells. MethodThe SS model was induced in NOD/Ltj mice. The NOD/Ltj female mice aged nine weeks were selected and randomly assigned into model group，HRP group （7.15 g·kg-1·d-1），and hydroxychloroquine （HCQ） group （1.30 g·kg-1·d-1）， and female BALB/c mice in the same age were selected and assigned into the normal group， with six mice in each group. Drug intervention lasted eight weeks. The water consumption and salivary flow rate （SFR） of each group were recorded. The pathological staining results of the submandibular gland of mice in each group were observed and scored. AQP5 expression was determined by immunohistochemistry （IHC） and Western blot. ResultCompared with the normal group， the model group showed increased water consumption （P<0.05） and reduced SFR （P<0.05）. Compared with the model group， the HRP group showed decreased water consumption （P<0.05） and increased SFR （P<0.05）， and the HCQ group showed increased SFR （P<0.05）. In terms of histopathological results of the submandibular gland，compared with the normal group，the model group showed increased pathological score， number of lymphocyte infiltration foci，and percentage of lymphatic infiltration area （P<0.05）. Compared with the model group， the HRP group showed reduced pathological scores and number of lymphocyte infiltration foci （P<0.05）， and the HRP group and the HCQ group showed reduced percentage of lymphatic infiltration area（P<0.05）. The results of IHC and Western blot showed that compared with the normal group，the model group showed down-regulated expression level of AQP5 protein （P<0.05）， and compared with the model group and the HCQ group，the HRP group showed up-regulated expression level of AQP5 protein （P<0.05）. ConclusionHRP can improve the secretion function of submandibular gland acinous cells and glandular structure injury in SS model mice， and its mechanism may be related to the up-regulation of AQP5 protein expression level in submandibular gland cells.

Values of serum cystatin C, serum and glucocorticoid-regulated kinase 1 and homocysteine in predicting postoperative lymph node metastasis in patients with lung cancer / 肿瘤研究与临床

Objective:To explore the correlation of serum cystatin C (CysC), serum and glucocorticoid-regulated kinase 1 (SGK1) and homocysteine ??(Hcy) with postoperative lymph node metastasis in patients with lung cancer and their predictive values.Methods:One hundred and thirty-one patients with stage Ⅰ-Ⅲ A non-small cell lung cancer (NSCLC) who underwent tumor resection and systematic lymph node dissection in Meishan Hospital of Traditional Chinese Medicine from November 2016 to June 2018 were prospectively selected. Patients received a 3-year follow-up after surgery, and were classified into metastasis group (42 cases) and non-metastasis group (89 cases) according to the presence or absence of lymph node metastasis during the follow-up period. Serum CysC, SGK1 and Hcy levels were detected at the 1st day after surgery, and the levels of the three indicators were compared among patients with different TNM stages, differentiation degrees and histological types. Meantime, the clinicopathological characteristics and levels of the three indicators were also compared between metastasis group and non-metastasis group. Spearman analysis was conducted to discuss the correlation between the three indicators and clinicopathological characteristics of patients. Multivariate logistic regression analysis was performed to screen the factors affecting postoperative lymph node metastasis (the median levels of CysC, SGK1 and Hcy were used as the cut-off values, > the median level was a high level). Taking the pathological examination results as the gold standard, receiver operating characteristic (ROC) curve was applied to evaluate the predictive value of level of the three indicators alone or in combination for postoperative lymph node metastasis. Results:The serum levels of CysC, SGK1 and Hcy in patients with TNM stage Ⅲ A were higher than those in patients with stageⅠ-Ⅱ; the serum levels of CysC, SGK1 and Hcy in patients with poorly differentiated tumors were higher than those in patients with medium and well-differentiated tumors; the serum levels of CysC, SGK1 and Hcy in patients with non-squamous cell carcinoma were higher than those in patients with squamous cell carcinoma; the differences were statistically significant (all P < 0.05). Spearman correlation analysis showed that serum CysC, SGK1 and Hcy levels were correlated with TNM stage ( r values were 0.454, 0.672 and 0.645), differentiation degree ( r values were -0.399, -0.403 and -0.451), histological type ( r values were 0.528, 0.760 and 0.611) (all P < 0.001). Compared with non-metastasis group, an elevation was found in serum levels of CysC, SGK1 and Hcy in metastasis group [(1.37±0.30) mg/L vs. (1.16±0.25) mg/L, (53±4) pg/ml vs. (41±3) pg/ml, (18.3±2.3) mol/L vs. (15.4±1.8) mol/L] (all P < 0.001). Multivariate logistic regression analysis showed that TNM stage Ⅲ A ( OR = 2.944, 95% CI 1.556-6.847, P = 0.004) and high level of CysC (> 1.23 mg/L, OR = 2.431, 95% CI 1.402-5.226, P = 0.008), high level of SGK1 (>50 pg/ml, OR = 4.010, 95% CI 1.815-11.748, P = 0.004), high level of Hcy (> 16.8 μmol/L, OR = 3.742, 95% CI 1.747-9.142, P = 0.001) were independent risk factors for postoperative lymph node metastasis. ROC curve analysis showed that for predicting postoperative lymph node metastasis, the area under the curve (AUC) of serum CysC, SGK1 or Hcy level alone was 0.769, 0.808 and 0.816, the AUC of CysC+Hcy, CysC+SGK1 and Hcy+SGK1 was 0.889, 0.890 and 0.910, and the AUC of the three indicators was 0.936. Conclusions:Levels of serum CysC, SGK1 and Hcy in NSCLC patients with postoperative metastasis are higher than those in patients without metastasis, and the levels of the three are positively correlated with the TNM stage and histological type, and negatively correlated with the differentiation degree. The combined detection of the three has good predictive value for postoperative lymph node metastases in NSCLC patients.

Analysis of factors related to hemocytopenia and interstitial lung disease secondary to primary Sj?gren's syndrome / 中华风湿病学杂志

Objective:To detect the factors related to hemocytopenia and interstitial lung disease (ILD) secondary to primary Sj?gren's syndrome (pSS) in in-patients.Methods:Clinical characteristics of patients with pSS hospitalized in China-Japan Friendship Hospital from March 2014 to October 2020 were retrospectively analyzed. Patients were divided into different groups according to hemocytopenia and ILD. Chi-square test and Mann-Whitney U test were used to compare data in subgroups, and logistic regression were used to detect factors related to hemocytopenia and ILD secondary to pSS. Results:Five hundred and seventy-one inpatients with pSS were included in this study and the female: male ratio was 8∶1. Two hundred and seventy five of included patients had hemocytopenia (48.2%) and 180 patients had ILD (31.5%). Compared with patients without hemocytopenia, patients with hemocytopenia had higher ratio in low C3 [ OR=2.326, 95% CI(1.483, 3.650), P<0.01] and elevation of erythrocyte sedimentation rate (ESR) [ OR=1.912, 95% CI(1.233, 2.964), PP<0.01) . Compared with patients without ILD, patients with ILD showed higher ratio in male[ OR=2.509, 95% CI(1.269, 4.959), P<0.01) and fatigue [ OR=5.190, 95% CI(5.190, 13.931), P<0.01) , lower positive rate of anti-SSA antibody [ OR=0.392, 95% CI(0.230, 0.668), P<0.01) and anti-CENPB [ OR=0.337, 95% CI(0.145, 0.782), P<0.01] antibodies, and lower ratio in low C3[ OR=0.332, 95% CI(0.189, 0.582), P<0.01]. Conclusion:Low C3 and high ESR may be risk factors for developing hemocytopenia in patients with pSS. Men with pSS may be susceptible to ILD, while pSS patients with ILD may have lower ratio in positive anti-SSA antibody, positive anti-CENPB antibody and low C3. All of these findings are yet to be validated by future prospective cohort studies.

Objective To investigate the effect of all-trans retinoic acid (at-RA) on fetal alveolar epithelial type Ⅱ cells (fAEC Ⅱ s) proliferation and the expression of pulmonary surfactant C (SPC) as well as aquaporin 5 (AQP5).Methods fAEC Ⅱ s were isolated and purified from fetal lung of pregnant SD rats (19 days).After being cultured for 1 day,and the fAEC Ⅱ s were interfered by at-RA for 1,2 and 3 days.Cell proliferation,viability as well as growth state,expressions of SPC mRNA as well as AQP5 mRNA and expressions of protein SPC as well as AQP5 were respectively detected by using 4,5-dimethylthiazol-2-yl-2,5-diphenyltetrazolium bromide (MTT),inverted microscope,real-time fluorescence quantitative PCR (RT-PCR) and Western blot.Results (1) When fAEC Ⅱ s were treated with at-RA for 1 day,and the cell proliferation and viability did not change (P ＞ 0.05),while the proliferation and viability were significantly improved in 2 days (P ＜ 0.05),and the difference was the most obvious (P ＜ 0.05) at 3 days.(2)Compared with the control group,the cell growth state was better,and the cell adherence was tighter and the refraction was higher in at-RA group.(3) Compared with the control group,at-RA up-regulated the expressions of AQP5 mRNA and AQP5 protein(t =-19.58,-10.44,-16.01,-46.25,-12.79,-27.96,all P ＜ 0.05),and the percentages of control group were 281.07％,766.67％,1 163.33％ and 792.65％,1 310.52％,1 561.56％ in 1,2 and 3 days respectively.(4) Compared with control group,the expressions of SP-C mRNA and SPC protein were up regulated when cells were exposed to at-RA for 1 and 3 d,but while they were down-regulated at 2 days(protein:the percentages of control group were 615.480％,369.450％ and 11.269％,respectively ; mRNA:728.33 ％,400.83 ％,66.57％,respectively)(t=-26.34,-25.26,13.80,-25.25,-31.71,9.12,all P＜0.05).Conclusions at-RA can promote the proliferation and differentiation of fAEC Ⅱs,enhance the fAEC Ⅱ s viability,and improve the expression of SPC and AQP5.

Effects of T-2 Toxin on Testosterone Biosynthesis in Primary Cultured Leydig Cells of Mice / 环境与健康杂志

Objective To investigate the effects of T-2 toxin on testosterone biosynthesis in primary cultured Leydig cell derived from the mouse testis.Methods Leydig cells isolated from Kunming male mice were adjusted to 5?105/ml and the purity was identified by the modified 3?-hydroxysteroid dehydrogenase(HSD) staining method.Blank control group(treated with 0 ng/ml hCG and 0 mol/L T-2 toxin),inductive control group(treated with 10 ng/ml hCG and 0 mol/L T-2 toxin),low dose T-2 toxin exposure group(treated with 10 ng/ml hCG and 10-9 mol/L T-2 toxin),middle dose T-2 toxin exposure group(treated with 10 ng/ml hCG and 10-8 mol/L T-2 toxin) and high dose T-2 toxin exposure group(treated with 10 ng/ml hCG and 10-7 mol/L T-2 toxin) were designed,respectively.The testosterone level was measured after 24 h of incubation.Results After 24 hours culture in liquid medium contained serum,the fresh isolated Leydig cells grew well and the purity exceeded 90%.Through 10 ng/ml hCG induce,the testosterone level of Legdig cells increased significantly and the difference compared to blank control was of statistical sense(P

Thyroxine treatment for elderly patients with heart failure and sick euthyroid syndrome / 老年心脏病学杂志（英文版）

Objectives To evaluate the effect of thyroid hormone therapy with low dose of thyroxin on cardiac function in elderly patients with heart failure and sick euthyroid syndrome. Methods Forty-seven patients (33 males and 14 females, mean age 85.9+4.6 years,ranging from 80 to 99 years) with chronic heart failure (NYHA Ⅱ-Ⅳ) and low triiodothyronine (T3) state were randomly allocated to the treatment group or control group. The treatment group patients received oral administration of levothyroxine sodium (Euthyrox) 25-50mg/d in addition to conventional therapy of heart failure, whereas patients in control group were given conventional therapy only. Serum level of total T3 (TT3), free T3 (FT3), total thyroxine (TT4), free thyroxine (FT4), and thyroid-stimulating hormone (TSH) were determined. For both groups, left ventricular ejection fraction (LVEF) and stroke volume (SV) were assessed by two-dimensional echocardiography before and at 8 weeks after treatment. The changes of these parameters after the treatment were evaluated by adjusting heart rate in the two groups. Results The reduced serum T3 level in the treatment group was corrected after thyroid hormone therapy,and these patients had a significant improvement in cardiac function after treatment. By contrast, in the control group only changes of serum TT3 and TT4 levels and SV and LVEF after treatment were statistically significant. The heart rate-adjusted mean SV and LVEF in both groups were also increased, which was significantly greater in the treatment group than in the control group. Conclusion In the elderly patients with heart failure and sick euthyroid syndrome, addition of thyroxine at a low dosage to the conventional treatment could effectively improve the low T3 state and cardiac function independent of changes of heart rate.

Diagnosis and treatment of primary small bowel tumors / 中国普通外科杂志

Objective　To study the clinical manifestation of small bowel tumors and the prognostic factors. Methods　Retrospective analysis of the clinical data were made on 42 cases of primary small bowel tumors (except periampullary tumors) admitted to our hospital from 1974 to 1999. Results　In this series, there were 6 cases of benign small bowel tumors, 5 of them were leiomyoma and 1 adenoma. Of the 36 cases of malignant 　tumors, there were malignant lyphoma in 17 cases (47.2%), adenocarcinoma in 11 (30.6%),　 leiomyosarcoma in 6(16.7%), carcinoid tumor in 1 (2.8%) and neurofibrosarcoma in 1 (2.8%). There was no characteristic clinical sign in small bowel tumors; endoscopy and barium series were the main diagnostic methods. About 50 per cent of patients with malignancy had metastasis, and only 18 cases (50%) received radical resection. Follow-up were available on 36 cases. The overall 5-year survival rate in the patients with malignant small bowel tumors was 47.3%. Multivariate analysis showed that metastasis and diameter of tumors were the main prognostic factors of the 5-year survival. Conclusions　Early diagnosis and early treatment play the key roles in improving the prognosis of malignant small bowel tumors. Radical resection should be taken if no metastasis is found.
