ABSTRACT
As an effective prescription for the treatment of rheumatoid arthritis (RA), Huangqin Qingre Chubi capsule (HQC) is still blank in quality control. This study aims to explore quality markers (Q-markers) for HQC in the treatment of RA by integrating network pharmacology and pharmacokinetics. By constructing the visualization network of "pharmacodynamic ingredient-target-pathway", the potential Q-Marker of HQC treatment for RA was preliminatively predicted. A rat model of rheumatic heat obstruction syndrome collagene-induced arthritis (CIA) was established to elucidate the dynamic quantification law of pharmacodynamic components of HQC in the disease state of rats. To establish the inflammatory model of RA synovial fibroblasts (MH7A) induced by tumor necrosis factor-α (TNF-α) in vitro. The effects of active ingredients on protein expression of sphingosin kinase-1 (Sphk1) and p-SphK1 were detected. The network pharmacological results showed that baicalin, geniposide, luteolin, coixol and amygdalin were the important active components of HQC treatment for RA. Quantitative analysis results further verified the measurability of these five components. The expression of Sphk1 and p-SphK1 was significantly inhibited by geniposide and baicalin by Western blotting. The above studies determined that the above 5 components could be used as Q-markers in the treatment of RA by HQC. This experiment was approved by the Experimental Animal Ethics Committee of Anhui University of Chinese Medicine (approval number: AHUCM-rats-2021049). All procedures were conducted in strict accordance with the principles of animal use and care.
ABSTRACT
Rheumatoid arthritis (RA) is an autoimmune disease with angiogenesis, inflammatory factor infiltration and joint destruction as the main pathological features. Angiogenesis promotes the development of RA and plays an important role in its pathogenesis. The hypoxia-inducible factor (HIF)-vascular endothelial growth factor (VEGF)-angiopoietin-2 (Ang-2) signal transduction is a critical pathway to induce synovial angiogenesis. Targeting HIF-VEGF-Ang-2 signal transduction to inhibit synovial angiogenesis is a promising approach for RA treatment. This article reviews the role and mechanism of HIF-VEGF-Ang-2 signal transduction-mediated synovial angiogenesis in RA, in order to provide a new target and strategy for RA treatment.
ABSTRACT
Gastrointestinal stromal tumors(GISTs)in the stomach,duodenum,and rectum have low occurrence,and the coexistence GISTs in three parts with neurofibromatosis type Ⅰ(NF-Ⅰ)is even rare.This paper reports a case of GISTs with a family history of NF-Ⅰ.There were multiple nodular masses of different sizes on the patient's face,trunk,and limbs.The patient was admitted due to chest tightness for 5 days and black stools for 1 day.Enhanced CT examination of the abdomen suggested multiple space-occupying lesions in the upper abdomen with multiple small nodules under the abdominal wall,and neurofibromatosis and intestinal stromal tumor cannot be excluded.Finally,surgical pathology confirmed that the multiple tumors in the abdominal cavity were GISTs.The case was confirmed as wild-type GISTs by genetic testing,and the patient recovered well nearly one year after the operation.

ABSTRACT
Orthostatic intolerance(OI)is the most common type of neurally mediated syncope in children. At present,the pathogenesis of OI in children is not yet clear,but in recent years,studies have found that the deficiency or lack of calcium,vitamin D are correlated with OI. Calcium ion is a second messenger that participates in the process of intercelluar communication. It has a wide range of biological effects in many tissues and cells in the body. Calcium ion plays an important role in children′s OI and other cardiovascular diseases. Calcium,vitamin D deficiency or abnormality of channel protein kinase may influence the occurrence and outcome of OI by influencing the activation of cardiac mus-cle cells,vascular endothelial cells and platelet. In this paper,the relationship between calcium,vitamin D and OI and its possible mechanism of action are discussed.
ABSTRACT
In order to study the chemical constituents of n-butanol fraction of ethanol extract from Chinese agarwood induced by artificial holing, various chromatographic techniques were carried out to isolate compounds, and the structures of compounds were determined through a combined analysis of physicochemical properties and spectroscopic evidence. Seven compounds were obtained and identified as selina-3,11-dien-9,15-diol (1), aquilarone D (2), 5α,6β,7α,8β-tetrahydroxy-2-[2-(2-hydroxyphenyl)ethyl]-5,6,7,8-tetrahydrochromone (3), 6,7-dimethoxy-2-[2-(4-methoxyphenyl)ethyl]chromone (4), syringin (5), methyl (Z)-p-coumarate (6), and 4'-methoxycinnamic acid (7), among which compound 1 was a new compound and compounds 5-7 were isolated from agarwood for the first time. The bioactivity assay results concluded that compounds 6 and 7 showed certain nematicidal activity against Panagrellus redivivus, and compounds 4, 6 and 7 exhibited cytotoxicity against BEL-7402, SGC-7901 and A549 carcinoma cell lines.
ABSTRACT
<p><b>OBJECTIVE</b>To observe the effects of ginsenoside Rb1 (GRb1) on the oxidative stress in the skeletal muscles of rats with postoperative fatigue syndrome (POFS) and to study its anti-fatigue mechanisms.</p><p><b>METHODS</b>The POFS model was established using resection of 70% of mid-small intestine. Ninety-six Sprague-Dawley (SD) rats were screened using grasping test. The rats were randomly divided into the control group, the model group, and the GRb1 treated group (at 10 mg/kg) by the body weight. The maximum grip strength of rats was detected on the 1st, 3rd, 7th, and 10th day after operation, respectively. The contents of malondialdehyde (MDA), the activities of superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GSH-PX) were detected.</p><p><b>RESULTS</b>Compared with the model group, the maximum grip strength was obviously enhanced on the postoperative day 7 and 10 (P < 0. 05), the MDA content obviously decreased on the postoperative day 3 and 7 (P < 0.05), the SOD activity obviously increased in the GRb1 treated group (P < 0.05). There was no obvious change in the activities of CAT and GSH-PX among the three groups at each time point (P > 0.05).</p><p><b>CONCLUSION</b>GRb1 could reduce the oxidative stress injury in the skeletal muscles, improve the activities of antioxidant enzymes, and enhance the functions of the skeletal muscles in POFS rats, which may be important reasons for fighting against POFS.</p>

<p><b>OBJECTIVE</b>To explore the mechanism of postoperative fatigue syndrome(POFS) by detecting the change of central monoamine neurotransmitters in a rat model after major abdominal surgery.</p><p><b>METHOD</b>Eighty-four rats were randomly divided into fatigue assessment groups (including model group and sham group) and experimental groups (including postoperative day 1, 3, 5, 7, and 14 recovery groups and the corresponding control groups). Postoperative fatigue was evaluated after surgery. The brains were removed thereafter to detect the levels of 5-hydroxytryptamine (5-HT), norepinephrine (NE), dopamine (DA) in the hippocampus, midbrain, hypothalamus by high performance liquid chromatography. Serum free tryptophan (f-Trp) and branched-chain amino acids (BCAA) were measured.</p><p><b>RESULTS</b>The level of 5-HT increased to the highest at postoperative day 3, but reduced rapidly to the minimum at postoperative day 5, and then gradually recovered to the preoperative level. There was significant difference of 5-HT among experimental groups (P<0.05), also between the postoperative 24 hrs group and control groups (P<0.05). f-Trp and the ratio of f-Trp/BCAA increased in the early postoperative period, reduced to minimum at postoperative day 5. f-Trp was still lower compared to the control group at postoperative day 14, while the ratio of f-Trp/BCAA and BCAA restored to control level. Both of them were significantly different among experimental groups (P<0.05), also between the experimental groups and control groups (P<0.05).</p><p><b>CONCLUSION</b>Changes of f-Trp, the ratio of f-Trp/BCAA, and central 5-HT may play an important role in the development of POFS.</p>

To compare the efficacy of interferon and thymosin alpha-1 combination therapy with interferon monotherapy for HBeAg positive chronic hepatitis B. The relevant randomized controlled trials were searched throughout PubMed, EBSCO, Cochrane Library, CBMdisc, VIP, WanFang since Janurary 1990. Studies were included if patients were followed up for at least 6 months after cessation of treatment. Meta-analysis was carried out with RevMan5.0 software. Subgroup analyses were used at different time of observation. Seven randomized controlled trials were included(535 patients in total). According to the results of meta-analysis, the combination therapy was remarkably more effective than monotherapy both at the end of the treatment and the follow-up in terms of HBV-DNA negative rate (54.9% vs 36.3%, OR=2.39, 95% CI=1.64-3.49, P value is less than 0.01; 58.6% vs 30.7%, OR=3.68, 95% CI=2.51-5.41, P value is less than 0.01, respectively), ALT normalization rate (74.5% vs 60.9%, OR=1.94, 95% CI=1.26-3.00, P value is less than 0.01; 74.0% vs 55.6%, OR=2.36, 95% CI=1.54-3.62, P value is less than 0.01, respectively), HBeAg loss rate (56.9% vs 36.7%, OR=2.38, 95% CI=1.61-3.51, P value is less than 0.01; 62.2% vs 33.2%, OR=3.42, 95% CI=2.31-5.06, P value is less than 0.01, respectively) , and HBeAg seroconversion rate (40.1% vs 29.0%, OR=1.65, 95% CI=1.10-2.47, P value is less than 0.05; 47.0% vs 29.5%, OR=2.13, 95% CI=1.43-3.16, P value is less than 0.01, respectively); the HBsAg loss rate of the combination therapy group was significantly higher than that of the monotherapy group only at the end of the follow-up (9.8% vs 3.7%, OR=2.92, 95% CI=1.09-7.76, P value is less than 0.05). Interferon and thymosin alpha-1 combination therapy achieves superior effect with no increase in the adverse effects as compared to interferon monotherapy for HBeAg positive chronic hepatitis B.

<p><b>OBJECTIVE</b>To evaluate the effect of the combined use of Shenmai Injection (SMI) and enteral nutrition on postoperative fatigue syndrome (POFS) in patients with gastric cancer (GC).</p><p><b>METHODS</b>Fifty-eight GC patients were randomized into the parenteral nutrition group (PNG, 19 cases), enteral nutrition group (ENG, 19 cases) and combined treatment group (CTG, 20 cases). The post-operative recovery in patients was observed; patients' conditions of fatigue, mood and sleep were evaluated respectively by visual analogue scale of fatigue, profile of mood states (POMS) and Pittsburgh sleep quality index (PSQI). Meanwhile, nutritional variables, such as serum contents of total protein, albumin, pre-albumin, were measured at different time points: before operation (d0) and the 1st, 5th, and 9th day (d1, d5 and d9) after operation. Immune variables such as subsets of lymphocytes (CD3, CD4, CD8), serum immunoglobulins (IgG, IgM, IgA) were also determined.</p><p><b>RESULTS</b>Conditions of recovery, POMS and PSQI were better and the postoperative fatigue reduced more significantly in CTG than those in the other two groups (P < 0.05). On d9, levels of pre-albumin, CD3, CD4, CD4/CD8 in CTG were significantly higher than those in the PNG and ENG (P < 0.05), meantime, levels of albumin and IgA were higher in CTG than those in PNG (P < 0.05).</p><p><b>CONCLUSION</b>Combined treatment of SMI and enteral nutrition can regulate mood and sleep to some extents, and reduce the postoperative fatigue through improving nutritional status and immune function, thus speeding up the recovery of patients.</p>
