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).

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.

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 â ¡ 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.

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.

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
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.

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.

Wound healing is a complex pathophysiological process that occurs frequently in everyday pathology and remains a challenge during the treatment of trauma. Previously, we prepared silver nanoparticle/chitosan oligosaccharide/poly(vinyl alcohol) (PVA/COS-AgNP) nanofibers via an electrospinning technique. These nanofibers promoted the proliferation of human skin fibroblasts (HSFs) and the expression of transforming growth factor TGF-ß1 in the early stage of wound repair, although the specific mechanisms remain unclear. Therefore, considering that TGF-ß1 has emerged as a major modulator of wound healing, the objective of this study was to further understand whether the molecular mechanisms responsible for PVA/COS-AgNP nanofiber-mediated wound healing include the TGF-ß1/Smad signal transduction pathway. In this study, we used human skin fibroblasts (HSFs) to investigate the molecular and cellular mechanisms underlying PVA/COSAgNP nanofiber-mediated wound healing. Cell adhesion and proliferation experiments, immunofluorescence staining, hydroxyproline content measurements, flow cytometry, quantitative real-time PCR (qRT-PCR), and western blotting (WB) were used to analyze the wound healing mechanisms of human skin fibroblasts treated with various concentrations of PVA/COS-AgNP nanofibers and the combined application of silver nanofibers and SB431542 (an inhibitor of the TGF-ß1 receptor kinase). Our study showed that PVA/COS-AgNP nanofibers markedly promoted fibroblast proliferation, collagen synthesis, and cell adherence. We also found that treating fibroblasts with PVA/COS-AgNP nanofibers stimulated cell cycle progression from G1 into the S and G2 phases, reducing the proportion of cells in the G0/G1 phase and inducing S and G2/M arrest. Importantly, the cell factors associated with the TGF-ß1/Smad signal transduction pathway, such as TGF-ß1, TGFßRI, TGFßRII, pSmad2, pSmad3, collagen I, collagen III, and fibronectin were also up-regulated. Moreover, this enhancing effect was markedly inhibited by the TGFßRI receptor inhibitor, SB431542. Therefore, the PVA/COS-AgNP nanofibers used to accelerate wound healing do so by activating the TGF-ß1/Smad signal transduction pathway.

Wound healing occupies a remarkable place in everyday pathology and remains a challenging clinical problem. In our previous study, we prepared a silver nanoparticle/chitosan oligosaccharide/poly(vinyl alcohol) (PVA/COS-AgNPs) nanofiber via electrospinning and revealed that it could promote wound healing; however, the healing mechanism remained unknown. Therefore, we aimed to clarify the mechanism underlying the accelerated healing effect of the PVA/COS-AgNPs nanofiber. The TGFß1/Smad signaling pathway is actively involved in wound healing. Considering the key role of this signaling pathway in wound healing, our preliminary study showed that the TGFß1 level was significantly increased during the early stage of wound healing. Thus, in this study, hematoxylin-eosin, Masson's trichrome, immunofluorescent staining, hydroxyproline content, quantitative real-time polymerase chain reaction, and Western blot analyses were used to analyze the wound healing in a rat model treated with gauze, the PVA/COS-AgNPs nanofiber, and the nanofiber plus SB431542 (an inhibitor of TGFß1 receptor kinase). The results showed that the PVA/COS-AgNPs nanofiber promoted wound healing and upregulated the expression levels of cytokines associated with the TGFß1/Smad signaling pathway such as TGFß1, TGFßRI, TGFßRII, collagen I, collagen III, pSmad2, and pSmad3. Inhibiting this pathway with SB431542 resulted in prevention of the PVA/COS-AgNPs nanofiber-associated salutary effects on the early stage of wound healing and relative cytokines expression. In conclusion, the wound healing effect of the PVA/COS-AgNPs nanofiber involves activation of the TGFß1/Smad signaling pathway.

OBJECTIVE: To investigate the effect of Chinese herbal medicines for nourishing yin, supplementing qi, and activating blood on the reproductive endocrine-immune network and its mechanisms in patients with primary Sjogren's syndrome (pSS). METHODS: Seventy pSS patients were randomly assigned to two groups using a randomized digital table: the integrative therapy group (36 cases) and the control group (34 cases). Thirty healthy subjects were taken as a normal group. The control group was treated with hydroxychloroquine sulfate tablets alone, and the integrative therapy group was treated by Chinese herbal medicines for nourishing yin, supplementing qi, and activating blood combined with hydroxychloroquine sulfate tablets. The treatment course was 6 months for both groups. Before and after treatment, serum estradiol (E2), testosterone (T), luteinizing hormone (LH), prolactin (PRL) by radioimmunoassay and immunoglobulin (IgG) by immunodiffusion, erythrocyte sedimentation rate (ESR) by Westergren, interferon-γ (IFN-γ) and interleukin-4 (IL-4) by enzyme linked immunosorbent assay were determined. RESULTS: E2 and T levels in all patients were lower than those of normal subjects before treatment (P<0.05) and were increased significantly after 6-month treatment (P<0.05). ESR, FSH, LH, IgG, IFN - γ, IL - 4 and ratios of E2/T, and IFN -γ/IL in the patients were higher than those of normal subjects before the treatments (P<0.05), and were reduced significantly after the treatments (P<0.05). The T and IFN - γ levels and E2/T ratio in the patients treated with integrative therapy were reduced significantly compared with the control group (P<0.05). However, the PRL levels before and after treatment were not significantly changed in the two groups (P>0.05). The ratios of E2/T and IFN -γ/IL-4, and levels of IgG and ESR were positively correlated before and after treatment (P<0.05). CONCLUSIONS: The ratios of E2/T and IFN -γ/IL-4 might be used as indicators of pSS activity. Chinese herbal medicines for nourishing yin, supplementing qi, and activating blood combined with Western medicine could improve the therapeutic effect by regulating the reproductive endocrine-immune network in pSS patients.

OBJECTIVE: To research the application and clinical effect of titanium elastic nails (TEN) for the treatment of closed clavicular fracture in elder children. METHODS: From October 2010 to December 2012,16 elderly children with clavicular fracture of elder children were treated with internal fixation, including 9 boys and 7 girls with an average age of 14.2 yeats old ranging from 9 to 17 years. The mean time between injury and surgery was 2 to 6 days. Thirteen patients had a transverse fractures; 3 patients had a oblique fractures, excluding the long-oblique patients. Neer function score after 3 months follow-up and the shoulder activity degree after 3 weeks followed were compared respectively between the injured side and healthy side. Fracture reduction and healing were followed up by X-rays to analyze internal fixation with TEN technique. RESULTS: All patients were healed well after surgery. There were 2 cases with soft tissue irritation. No cases of infection, TEN broken, delayed healing or skin bursting were observed. All patients were followed up for 3 to 10 months,with an average of 7.2 months. There were no significant differences (t=2.12, P>0.05) between the healthy side (98.75±2.70) and injured side(96.69±6.22)of Neer score at 3 months during followed up. The shoulder activity at 3 weeks during followed up was different between both sides (P<0.05). The intramedullary nail was removed after X-rays at 12-18 weeks during followed up showed good bone healing,and the shoulder function was recovered well. CONCLUSION: Internal fixation with TEN for the treatment of clavicular fracture has advantages of a limited invasion, beauty, safety and reliability. This technique provides an ideal fixation option for the treatment of clavicular fracture in elder children.

OBJECTIVE: To observe the effect of Chinese herbal medicine for nourishing yin, supplementing qi, and activating blood on the expression of interferon-γ (IFN-γ)/interleukin-4 (IL-4) in peripheral blood and disease activity in primary Sjogren's syndrome (pSS) patients, and to study the relationship between the immune balance of Th1/Th2 and the disease activity. METHODS: A total of 66 pSS patients were randomized with tossing coins method into two groups: the integrative therapy group (34 cases) and the control group (32 cases); and 28 healthy subjects were taken as the normal group. The integrative therapy group was treated by Chinese herbal medicines for nourishing yin, supplementing qi, and activating blood combined with hydroxychloroquine sulfate tablets and the control group was treated with hydroxychloroquine sulfate tablets. The treatment course was 3 months for both groups. The levels of serum immunoglobulin G (IgG), erythrocyte sedimentation rate (ESR), IFN-γ and IL-4 in peripheral blood were measured before and after treatment. RESULTS: Compared with the normal group, the levels of IgG, ESR, IFN-γ and IL-4 were significantly increased in pSS patients (P<0.05). Remarkably, after 3 months of treatment, these levels were dramatically decreased in both the integrative therapy group and the control group, although still higher than the normal group. The levels of IgG, ESR, IFN-γ and IL-4 in the integrative therapy group were lower than the control group and the same group before treatment (P<0.05). The ratio of IFN-γ/IL-4 also significantly decreased after treatment. Moreover, the level of IFN-γ and the ratio of IFN-γ/IL-4 in the integrative therapy group were significantly lower than the control group (P<0.05). For all patients the ratio of IFN-γ/IL-4 before and after treatment was positive correlated with the levels of IgG and ESR. CONCLUSION: Chinese herbal medicine for nourishing yin, supplementing qi, and activating blood can alleviate the disease activity of pSS by regulating the immune balance of Th1/Th2.

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.

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.

Textile dye effluents are typically characterized by strong color and recalcitrance, even at very low concentration. The process of enrichment of anionic azo dye on the surface of TiO(2) fibers followed by photosensitization degradation under ambient air conditions was extensively investigated. Adsorption isotherms and zeta potentials were used to describe the "dye/TiO(2) surface" interface, taking into account the effects of pH on the nature and population of the surface groups on the TiO(2) fibers. The extent of the photocatalytic degradation of dye on TiO(2) surface was determined by FTIR. N(2) adsorption isotherms and optical spectra were employed to investigate the effect of photosensitization. The adsorption of dyes on the TiO(2) surface occurs via electrostatic attraction through the formation of single- or multidentate-coordinated surface complexes. Almost complete photobleaching of the absorption band at 534 nm is achieved in ~4 h. Dye-sensitized TiO(2) fiber could absorb part of the visible light spectrum (λ < 600 nm). Interfacial electron transfer can potentially alter the degradation efficiency. The regenerated TiO(2) fiber could be reused for subsequent decolorization without a decline in adsorption efficiency compared with freshly prepared TiO(2) samples, which may be attributed to preservation of the hierarchical pore structure and restoration of the original surface properties. In summary, we propose an efficient "adsorption-photoregeneration-reuse" process applying TiO(2) fibers for the degradation of dyes in water.

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
