RESUMO

BACKGROUND: About 25% of pregnant women experience bleeding in the early stage, and half of them eventually progress to pregnancy loss. Progesterone serves as a useful biomarker to predict miscarriage in threatened miscarriage, yet its performance is still debated. AIM: To evaluate the performance of single serum progesterone predicting miscarriage in early pregnant patients with threatened miscarriage. METHOD: The online database was searched to yield the literature using the terms of 'Abortion', 'Miscarriage', and 'serum Progesterone', including PubMed, Scopus, Embase, Cochrane library, and China national knowledge infrastructure. Receiver operating characteristic (ROC) curve, likelihood ratio (LLR) and diagnostic odds ratio (DOR) and 95% confidence interval (CI) were computed. Publication bias was assessed by the deeks funnel plot asymmetry test. Subgroup analyses were conducted according to the progesterone level (< 12 ng/mL), recruited location and region, progesterone measurement method, exogenous progesterone supplement and follow up. RESULTS: In total, 12 studies were eligible to be included in this study, with sample sizes ranging from 76 to 1087. The included patients' gestational age was between 4 and 12 weeks. No significant publication bias was detected from all included studies. The threshold of progesterone reported ranged from 8 to 30 ng/ml. The synthesized area under the ROC curve (0.85, 95% CI 0.81 to 0.88), positive LLR (6.2, 4.0 to 9.7) and DOR (18, 12 to 27) of single progesterone measurement distinguishing miscarriage were relatively good in early pregnant patients with threatened miscarriage. When the threshold of < 12 ng/mL was adapted, the progesterone provided a higher area under the ROC curve (0.90 vs. 0.78), positive LLR (8.3 vs. 3.8) and DOR (22 vs.12) than its counterpart (12 to 30 ng/mL). CONCLUSION: Single progesterone measurement can act as a biomarker of miscarriage in early pregnant patients with threatened miscarriage, and it has a better performance when the concentration is <12 ng/mL. TRIAL REGISTRATION: PROSPERO (CRD42021255382).

RESUMO

OBJECTIVES: To quantify the effect of carnitine on glucose and lipid metabolic profiles and fertility outcomes in women with Polycystic ovary syndrome (PCOS). DESIGN: A systematic review and meta-analysis were conducted. PATIENTS: Women with PCOS diagnosed by Rotterdam or Androgen Excess Society (AES) criteria and taking carnitine supplement were assessment. MEASUREMENTS: Fertility outcomes (ovulation, clinical pregnancy, live birth, and miscarriage), lipid parameters (BMI, triglyceride, total cholesterol, high-density lipoprotein, low-density lipoprotein), fasting glucose and insulin, and Homeostatic Model Assessment for Insulin Resistance (HOMA-IR). RESULTS: In total, 839 participants were included in this analysis. The dosage of carnitine and treatment duration reported by studies varied from 250 mg to 3000 mg daily and 84 to 90 days, respectively. The publication bias was absent. Compared with placebo, carnitine significantly improved ovulation rates (RR 3.42, 95% CI 2.39 to 4.89, I2 = 0%) and pregnancy rates (RR 11.05, 95% CI 1.21 to 100.58, I2 = 79%). None of included studies reported live birth. After treatment, carnitine resulted in significant reductions relative to baseline in body mass index (BMI, MD -0.93 kg/m2, 95% CI -1.15 to -0.70, I2 = 55.0%), insulin levels (MD -2.47 mIU/L, 95% CI -4.49 to -0.45, I2 = 0%) and the Homeostasis Model Assessment index (MD -0.67, 95% CI -1.20 to -0.14, I2 = 0%) than placebo, but not for lipid profiles including triglyceride, total cholesterol, and low-density lipoprotein. CONCLUSION: With the available literature, carnitine seems to improve ovulation and clinical pregnancy and insulin resistance, BMI in women with PCOS. These effects are warranted to be further validated, due to insufficient statistical power.

RESUMO

In this study, ultra-high performance liquid chromatography-linear ion trap/electrostatic field orbit trap combined-type mass spectrometry(UPLC-LTQ-Orbitrap-MS) was used to analyze the main active components of Huangqi Guizhi Wuwu Decoction(HQGZ). A total of 50 active components were identified from HQGZ and 108 potential targets of the components related to the treatment of rheumatoid arthritis were retrieved based on network pharmacology, including 87 key targets, followed by Gene Ontology(GO) term enrichment and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment of the targets. The result indicated that HQGZ may exert therapeutic effects mainly through the sphingolipid signaling pathway, tumor necrosis factor(TNF) signaling pathway, as well as the positive regulation of ribonucleic acid(RNA) polymerase Ⅱ promoter transcription, inflammatory response and other biological processes. At the same time, cell experiment was performed to verify the key proteins in the TNF signaling pathway. The results demonstrated that HQGZ significantly reduced the expression of caspase-3(CASP3), TNF, relaxed(RELA) protein, and IkappaB kinase beta(IKBKB) in fibroblast-like synoviocytes induced by TNF-α. The results of UPLC-LTQ-Orbitrap-MS, network pharmacology and cell experiment showed that the active components in HQGZ may inhibit inflammatory response and regulate immune function and cell apoptosis by modulating key proteins in TNF signaling pathway to treat rheumatoid arthritis.

RESUMO

Gastrointestinal failure is a kind of severe systemic inflammatory response, and often complicated with multiple organ dysfunction syndrome. Integrated traditional Chinese and Western medicine have a better curative effect in treating it. This study collected the famous veteran TCM physician Yu Guoyou's 175 prescriptions for treating 89 cases of gastrointestinal failure, calculated the frequency of traditional Chinese medicines and their categories, and analyzed the medication regularity with system clustering method, so as to summarize Yu's frequently used drugs and prescriptions. The results showed the top three most frequently used drugs aremagnolia bark, bitter orange, and rhubarb, which are components of Xiaochengqi decoction; Among the traditional Chinese medicines, medicines of tonifying deficiency, regulating qi, clearing heat, eliminating phlegm and dissipating dampness are most commonly used. Among the tonic medicines, those for tonifying Qi accounted for 2/3, which was the largest proportion; At the same time, some new prescriptions and new drug combinations were excavated and could be used as the reference for clinical medication. According to the findings, when differentiating syndromes of gastrointestinal failure, Yu regards the spleen and stomach Qi deficiency as the root cause and the heat toxin, blood stasis, Qi stagnation and dampness as the symptoms. In the treatment of gastrointestinal function failure, Yu gives priority to strengthening spleen, regulating Qi and purgation, prescribes medicines for dissolving blood stasis and detoxication, dissipating dampness, clearing heat and eliminating phlegm according to syndrome types. In other words, the treatment is based on syndrome differentiation, and the prescription is modified according to symptoms. In particular, Yu attaches importance to stomach-Qi recuperation and gastrointestinal function recovery in the process of treatment.

RESUMO

The ralationship between traditional Chinese medicine (TCM) and intestinal microecology is increasingly being given more and more attention. Combined with the devolopment of intestinal microecology disciplines, effects of TCM on regulation of intestinal microecology have been gradually explained. Both clinical studies and animal experiments have confirmed that TCM can maintain the balance of intestinal microecology and regulate the intestinal flora. The author arrangemented the documents related to Chinese herbal compound adjusting intestinal flora in the recent ten years, summarized that the Chinese herbal compound which can strength spleen and replenish Qi, relax bowels and regulate Qi, dissipate dampness and check diarrhea, clear away heat and toxic materials, promote digestion and relieve stasis had certain regulation effects on intestinal microecology, providing basis for revealing the TCM essence of intestinal microecology.

RESUMO

Nitrogen-doped TiO2 nanopowders have been successfully synthesized by a one-step hydrothennal route under soft-chemistry conditions (150 degrees, 8 h) without high-temperature calcination using seven different types of nitrogen dopants: methylamine, ethylamine, diethylamine, ethylenediamine, triethylamine, triethanolamine and ammonia. X-ray diffraction, transmission electron microscopy, ultraviolet-visible spectroscopy, X-ray photoelectron spectroscopy, N2 adsorption-desorption isothenns and Fourier transform infrared spectroscopy were used to analyse the as-synthesized TiO2 powders. The results indicated that nitrogen was doped effectively and the structure and morphology of the titania samples were strongly influenced by the nitrogen sources. Among the investigated nitrogen sources, the diethylamine system was clearly superior to the other small-molecule amine or ammonia systems due to the broad-spectrum response (between 400 and 700 nm) of the interstitial nitrogen-doped TiO2 nanopowders. The diethylamine N-doped TiO2 had the largest pore volume (0.39 ml x g(-1)) and showed a well-aligned anatase phase. The visible-light photocatalytic degradation of liquid X-3B used as a probe reaction demonstrated that the removal rate over the diethylamine material reached 99.7% in 90 min.

RESUMO

OBJECTIVE: To observe the effect of Yangyin Yiqi Huoxue Recipe (YYHR) on expression of interferon-gamma (IFN-gamma), IL-2, IL-4, IL-10, and immune balance of Th1/Th2 in serum and submaxillary glands of non-obese diabetic (NOD) mice with Sjogren's syndrome (SS), and to explore its mechanisms. METHODS: Totally 32 NOD mice were randomly into 4 groups, i.e., the model group, the Chinese medicine group [CM, administered with YYHR at the dose of 0.4 mL by gavage (100 g/kg)], the Western medicine group [WM group, administered with hydroxychloroquine 0.4 mL by gavage (60 mg/kg)], and the combined group [administered with YYHR (50 g/kg) and hydroxychloroquine (60 mg/kg) 0.4 mL by gavage], 8 mice in each group. Eight Balb/C mice were recruited as the normal control group. Mice were sacrificed to withdraw blood after 8 weeks. The submaxillary gland was excised. Serum levels of IFN-gamma, IL-2, IL-4, and IL-10 were detected by ELISA. Protein expression of IFN-gamma, IL-2, IL-4, and IL-10 in submaxillary glands was detected by SP method. RESULTS: Compared with the normal group, levels of IFN-gamma, IL-2, IL-4, and IL-10 in serum and submaxillary glands all increased in the model group (P < 0.05). Levels of IFN-gamma and IL-10 in serum in the CM group and the combined group were lower than those of the WM group (P < 0.05). Serum levels of IFN-gamma and IL-2 in submaxillary glands in combined group were lower than those of the WM group (P < 0.05). The ratio of IFN-gamma/IL-4 in serum and submaxillary glands in the model group were higher than that of the rest groups (P < 0.05). Besides, it was the nearest to that of the normal group. CONCLUSIONS: YYHR could decrease the levels of Th1 and Th2 related cytokines and the ratio of IFN-gamma/IL-4 in serum and submaxillary glands of NOD mice with SS. It could achieve therapeutic effects through adjusting immune balance of Th1/Th2 in SS mice.

RESUMO

OBJECTIVE: To observe effect of prescriptions replenishing vital essence, tonifying Qi and activating blood on expression of tumor necrosis factor-alpha (TNF-alpha) and interleukin-IP (IL-1beta) in serum and submaxillary gland of non-obese diabetic (NOD) mice with Sjogren's syndrome. METHOD: Thirty-two NOD mice were divided into four groups at random: the model group, the traditional Chinese medicine (TCM) group, the hydroxychloroquine group, the TCM and western medicine (WM) group, with 8 mice in each group. Eight Balb/C mice were taken as the normal normal control group. The TCM group was orally administered with 0.4 mL decoction replenishing vital essence, tonifying Qi and activating blood (100 g x kg(-1)) everyday; the hydroxychloroquine group were given 0.4 mL hydroxychloroquine (60 mg x kg(-1)) everyday; the TCM WM group were given 0.4 mL decoction, replenishing vital essence tonifying Qi and activating blood (50 g x kg(-1)) and hydroxychloroquine (60 mg x kg(-1)) everyday. Mice were sacrificed after eight weeks, and their arterial blood and tissues of submaxillary gland were collected. The levels of TNF-alpha, IL-1beta in serum were detected by ELISA. Expressions of TNF-alpha, IL-1beta protein in submaxillary gland were detected by immunohisto-chemistry. RESULT: Compared with other groups, TNF-alpha, IL-1beta in serum and submaxillary gland in the model group were higher (P < 0.05). The normal group showed lower serum TNF-alpha level than other groups (P < 0.05), but without statistical significance compared with the TCM group. IL-1beta in serum in the TCM group and the TCM WM group were lower than that of the hydroxychloroquine group (P < 0.05), but without statistical significance compared with the normal group. TNF-alpha protein expression in the TCM group and the TCM WM group showed no significant difference compared with the normal group, whereas the TCM WM group were notably lower than that of the hydroxychloroquine group (P < 0.05). IL-1beta expression in the TCM WM group showed no significant difference compared with the normal group. CONCLUSION: The decoction replenishing vital essence, tonifying Qi and activating blood can decrease the levels of TNF-alpha, IL-1beta in serum and submaxillary gland of NOD mice with Sjogren's syndrome. It may improve pathological damage of submaxillary gland by regulating Th1/Th2 cell factors, in order to achieve the therapeutic effect on SS.

RESUMO

OBJECTIVE: To observe the effect of nourishing Yin, strengthening Qi and activating blood decoction on Fas/FasL in salivary glands of NOD mice with Sjogren's syndrome and their mRNA expression. METHOD: Thirty-two NOD mice were randomly divided into the model group, the traditional Chinese medicine group (TCM group, orally given 0.4 mL nourishing Yin, strengthening Qi and activating blood decoction as per 100 g x kg(-1) everyday), the hydroxychloroquine group (given 0.4 mL hydroxychloroquine as per 60 mg x kg(-1) everyday), the traditional Chinese medicine and western medicine group (TCM WM group, given nourishing Yin, Strengthening Qi and activating blood decoction 50 g x kg(-1) and hydroxychloroquine 60 mg x kg(-1), 0.4 mL everyday), with eight mice in each group. Eight Balb/C mice were selected as the normal control group (normal group). All of mice were killed after eight weeks, and their submaxillary glands were dissected. The expression levels of Fas/FasL were examined by immunohistochemical method, and the FasL mRNA was detected by RT-PCR. RESULT: The expression levels of Fas/FasL in salivary glands of the model group were higher than that of other groups (P < 0.05). The expression level of FasL of the normal group was much lower than that in the hydroxychloroquine group (P < 0.05). The relative expression level of Fas mRNA in salivary glands of the model group was higher than that in other groups, but the control group was notably lower than other groups (P < 0.05). The expression level of FasL mRNA in salivary glands of the model group was higher than that in TCM and TCM WM groups (P < 0.05). But the expression level in TCM WM group was notably lower than the hydroxychloroquine group (P < 0.05). CONCLUSION: The nourishing Yin, strengthening Qi and activating blood decoction could down-regulate the expression level of Fas/FasL in salivary glands of NOD mice with Sjogren's syndrome and their mRNA expression, and had a better efficacy after being combined with hydroxychloroquine. The nourishing Yin, strengthening Qi and activating blood decoction might treat the Sjogren's Syndrome by reducing apoptosis which is regulated by Fas/FasL

RESUMO

OBJECTIVE: To supply evidence for establishing the standard for Chinese medicine (CM) syndrome differentiation by investigating the distribution and characteristics of CM syndromes in patients with nonalcoholic fatty liver disease (NAFLD). METHODS: 928 NAFLD patients' symptoms, signs, tongue and pulse parameters were studied by clinical epidemiologic survey. And the results were analyzed by the cluster analysis and factor analysis. RESULTS: The results of cluster analysis showed that the CM syndrome typings of fatty liver patients were mainly classified as dampness heat accumulation, Pi deficiency with dampness phlegm, Gan-qi stagnation and Pi deficiency, phlegm stasis accumulation, and Gan-Shen insufficiency, which were in accordance with clinical practice. The results of factor analysis indicated that overweight/obesity, abdominal distension, hypochondriac pain, discomfort in the hepatic region were common "condition factors" of fatty liver patients. The 5 "syndrome factors" such as dampness heat accumulation, Pi deficiency with dampness phlegm, Gan-qi stagnation and Pi deficiency, phlegm stasis accumulation, and Gan-Shen insufficiency showed identification significance in syndrome typing. CONCLUSIONS: The basic CM syndrome typings of NAFLD were dampness heat accumulation, Pi deficiency with dampness phlegm, Gan-qi stagnation and Pi deficiency, phlegm stasis accumulation, and Gan-Shen insufficiency. The four parameters of fatty liver patients could be classified by statistical analysis as condition factors and syndrome factors (which could reflect CM syndrome characteristics), which could provide certain evidence for establishing CM syndrome differentiation standards.

RESUMO

The present study has evaluated effect of fluroxypyr concentrations 0-0.8 mg l(-1) (a widely-used herbicide for controlling annual or perennial weeds growth) on selected metabolic and stress-related parameters in Oryza sativa plants after 6 days of exposure. Increasing concentrations decreased shoot growth and accumulation of chlorophylls but had no effect on root biomass. Increasing doses led also to increase in superoxide radical, hydrogen peroxide and proline accumulation, while malondialdehyde, an indicator of lipid peroxidation, was constitutively elevated. Histochemical staining with nitroblue tetrazolium and 3, 3-diaminobenzidine were positively correlated with the generation of superoxide radical and H(2)O(2). The fluroxypyr-induced oxidative stress triggered significant changes in activities of superoxide dismutase, catalase, ascorbate peroxidase and peroxidase (POD). Activities of the antioxidant enzymes show a general increase at low fluroxypyr concentrations and a decrease at high fluroxypyr levels (except for POD). Analysis of naturing polyacrylamide gel electrophoresis confirmed these results. These data support the observation that fluroxypyr-triggered oxidative stress was responsible for the disturbance of the growth in the rice plants.

RESUMO

Napropamide is a widely used herbicide for controlling weeds in crop production. However, extensive use of the herbicide has led to its accumulation in ecosystems, thus causing toxicity to crops and reducing crop production and quality. Salicylic acid (SA) plays multiple roles in regulating plant adaptive responses to biotic and environmental stresses. However, whether SA regulates plant response to herbicides (or pesticides) was unknown. In this study, we investigated the effect of SA on herbicide napropamide accumulation and biological processes in rapeseed (Brassica napus). Plants exposed to 8 mg kg(-1) napropamide showed growth stunt and oxidative damage. Treatment with 0.1 mM SA improved growth and reduced napropamide levels in plants. Treatment with SA also decreased the abundance of O (2) (-.) and H(2)O(2) as well as activities of superoxide dismutase (SOD), catalase (CAT), and ascorbate peroxidase (APX), and increased activities of guaiacol peroxidase (POD) and glutathione-S-transferase (GST) in napropamide-exposed plants. Analysis of SOD, CAT, and POD activities using nondenaturing polyacrylamide gel electrophoresis (PAGE) confirmed the results. These results may help to understand how SA regulates plant response to organic contaminants and provide a basis to control herbicide/pesticide contamination in crop production.

RESUMO

Primary Sjögren's syndrome (pSS) is a chronic autoimmune disease with a long duration of illness, for which there is no cure. Patients often suffer from anxiety and depression due to various reasons, exhibiting a decline in their quality of life. Chinese medicine (CM) has certain advantages in the treatment of pSS, which not only helps relieve clinical symptoms and improve treatment outcomes, but also reduces anxiety and depression and improves the quality of life. Therefore, CM should be considered as early as possible given its effectiveness and synergistic effects in treating pSS.

RESUMO

PURPOSE: To investigate the effect of total glucoside of paeony (TGP) on gut microbiota in NOD mice with Sjögren's syndrome (SS), using high-throughput sequencing of 16SrRNA gene. METHODS: Twenty-four NOD mice were randomly assigned to 4 groups (n = 6 per group): sham group receiving deionized water (0.4 ml), hydroxychloroquin group receiving hydroxychloroquin (0.4 ml), TGP group receiving TGP (0.4 ml), and TGP + hydroxychloroquin group receiving 0.4 ml TGP and 0.4 ml hydroxychloroquin. Balb/c mice (n = 6) receiving 0.4 ml deionized water were used as a control group. After intragastric injection of drugs for 8 weeks, feces were collected for high-throughput sequencing of 16SrRNA gene. RESULTS: The sequencing of 16SrRNA gene resulted in 3686 OTUs, and 10 phyla and 69 genera were identified. Compared with the control group, the indices of Chao, Ace and Shannon in the other 4 groups were significantly lower (P < 0.05), and the Simpson index were significantly higher in the TGP, hydroxychloroquine, and sham groups (P < 0.05). Compared with the sham group, the indices of Chao, Ace and Shannon were significantly higher (P < 0.05), whereas the Simpson index was significantly lower (P < 0.05) in the TGP and TGP + hydroxychloroquine groups. At phylum level, Bacteroidetes was least abundant (36.1%), and Firmicutes was most abundant (56.28%) in the TGP + hydroxychloroquine group. Compared with the other 4 groups, Bacteroidetes was significantly less abundant (P < 0.05) and Firmicutes was significantly more abundant (P < 0.05) in the TGP + hydroxychloroquine group. Verrucomicrobia was most abundant (12.26%) in the hydroxychloroquine, and was significantly more abundant compared with the other 3 groups (P < 0.05). At genus level, compared with the control group, the abundance of Lactobacillus and Incertae of Phylum Firmicutes and Desulfovibrio of Phylum Proteobacteria was significantly increased, and the abundance of Bacteroides and Alloprevotella of Phylum Bacteroidetes and Pseudoflavonifractor of Phylum Firmicutes was significantly decreased in the TGP + hydroxychloroquine group (P < 0.05). Compared with the hydroxychloroquine group, the abundance of Akkermansia of Phylum Verrucomicrobia was significantly decreased in the TGP and TGP + hydroxychloroquine groups (P < 0.05). The abundance of Alistipes of Phylum Bacteroidetes and Desulfovibrio of Phylum Proteobacteria was significantly increased in the TGP + hydroxychloroquine group (P < 0.05). CONCLUSIONS: TGP increases the growth of many key beneficial bacteria, inhibits the growth of dominant pathogenic bacteria, and increases the diversity and abundance of gut microorganisms, especially when combined with hydroxychloroquine. Our findings suggest that TGP may be effective to treat SS by improving the microecological structure of the gut.

RESUMO

OBJECTIVE: To observe the effect of Yangyin Jiedu Huoxue Recipe (YJHR) on the degree of activity integral of systemic lupus erythematosus (SLEDAI) and plasma osteopontin (OPN), and its effect for hormone withdrawal in patients with systemic lupus erythematosus (SLE). METHODS: Seventy-eight patients were randomly assigned by a randomizing digital table to two groups, 42 patients in the treated group and 36 in the control group, all were treated with conventional Western medical treatment, and YJHR was given additionally to the treated group. Changes of SLEDAI and OPN, as well as the daily dosage of prednisone used were observed after 2 courses of treatment. RESULTS: SLEDAI and OPN were lowered in both groups, but the lowering in the treated group [9.17 +/- 4.12, (117.69 +/- 78.50) microg/L] was more significant than that in the control group [11.60 +/- 4.05, (151.09 +/- 83.90) microg/L, P<0.05]. The two indices were positively correlated. The dosage of prednisone daily used in the treated group (10.03 +/- 4.29) was reduced more than that in the control group (15.14 +/- 6.67, P<0.05). SLEDAI of all the patients before and after treatment had a positive relationship with OPN respectively (r=0.44, 0.39) (P<0.05). CONCLUSIONS: YJHR can suppress the activity of disease and be helpful for early withdrawal of prednisone in treating SLE. Plasma level of OPN is related with the activity of the disease.

RESUMO

BACKGROUND: The de Winter electrocardiography (ECG) pattern is a sign that implies proximal left anterior descending coronary artery occlusion in patients with chest pain. The previous view was that the de Winter ECG pattern is static. CASE SUMMARY: A 65-year-old man presented with sudden chest pain at rest associated with diaphoresis for 55 min. The first ECG showed only T-wave inversion in III and aVF leads. Another ECG was performed at the 100th minute, showing upsloping ST segments depressed with tall and symmetrical T waves in the precordial leads; the J point was raised by 0.1 mV at the aVR lead. The patient was referred to our catheterization laboratory. A third ECG showed ST segment elevation by 0.2 mV in the I and aVL leads. The patient underwent emergency coronary angiography, which revealed complete proximal left anterior descending coronary (LAD) occlusion. The second patient presented with a 1-h history of sudden-onset, severe, substernal crushing chest pain. The first ECG showed ST-segment elevation (0.1-1.7 mV) in I, aVL, and precordial leads. The patient was referred to the catheterization laboratory. On arrival, his symptoms alleviated, and ECG showed that the ST-segments had significantly fallen back. The third ECG showed a typical de Winter pattern. Coronary angiography revealed 99% stenosis of the middle LAD. CONCLUSION: The de Winter ECG pattern is transient and dynamic, and it reflects proximal or mid-LAD subtotal occlusion rather than total occlusion.

RESUMO

OBJECTIVE: To explore the change of intestinal microecology in patients with primary Sjogren's syndrome (pSS) and correlation with disease activity, and also discuss the therapy effect of Yangyin Yiqi Huoxue Recipe (, YYHD). METHODS: Sixteen pSS patients were enrolled in the present study, who received 3-month treatment of YYHR, 200 mL orally twice daily. Their pre-and post-test ESSDAI scores, erythrocyte sedimentation rate (ESR) and serum immunoglobulin G (IgG) levels were measured respectively. The 16SrDNA metagenomic sequencing was used to detect and analyze the abundance and diversity of intestinal bacteria flora and the proportion of bacteria at the levels of phylum, family, and genus, in comparision with those of 6 healthy subjects in the control group. RESULTS: The abundance and diversity of intestinal bacteria flora in pSS patients were lower than those of healthy subjects (P<0.05). After the treatment with YYHD, patients' ESSDAI score and levels of IgG and ESR have decreased significantly (P<0.05). At the phylum level, the proportions of Actinobacteria, Firmicutes, Fusobacteria and Proteobacteria have reduced sharply, while the proportions of Bacteroidetes, Teneriquetes and Candidate-division-TM7 have increased significantly by treatment (all P<0.05). At the classification level, such treatment has caused a significant decrease in the proportions of Bacteroidaceae, Ruminococcaceae, Veillonellaceae, and Enterobacteriacea (all P<0.05), but a significant increase in the proportion of Lachnospiraceae (P<0.05). At the genus level, the treatment has significantly decreased the proportions of Bifidobacterium, Bacteroides, Escherichia-Shigella, Faecalibacterium and Prevotella (all P<0.05), but significantly increased the proportion of Clostridia (P<0.05), close to the levels of healthy subjects (P>0.05). CONCLUSIONS: There exists an imbalance of intestinal microecology in pSS patients, which can be improved through the treatment with YYHD. Besides, such treatment can also improve the disease activity and adjust the diversity of intestinal bacteria flora, the composition and the abundance of intestinal flora.

RESUMO

As a new dosage form, TCM injection is commonly used in clinical practice. But the increasing events of adverse drug reactions (ADRs) could even seriously endanger patients' lives. The causes of TCM injection inducing ADRs might be the unstable quality of preparation; the irrational clinical use and operation; the sensitive physique of patient and the change of patients' primary illness, etc. For preventing the occurrence of ADRs, based on guaranteeing the stable quality of product, putting stress on accurate usages and normalized operations in clinical practice, enhancing the monitor on ADRs and the precautionary awareness in medical units are very important.
