OBJECTIVETo observe effects and mechanism of Dinggui gel paste analgesic anti-inflammatory.
METHODSEighty-four male KM mice weighted from 18 to 22 g and aged 4 to 5 weeks were randomly divided into 7 groups, named blank group, model group, matrix control group, Votalin group, high dosage of Dinggui gel paste group with group, equivalent dosage of Dinggui gel paste group, Dinggui gel paste group, 12 mice in each group. Except blank and model group, the other groups were paste ointment for 7 days, and one time a day, matrix control group were pasted isodose blank matrix gel patch. Pain threshold were tested at 30, 60, 90 and 120 min after the last ad-ministration. Hot plate test were performed by injection of 5% formalin for 20 µL on right hindfoot sole after the last administration. The cumulative time of mice licking right rear foot were observed at stage of I and II, and content of IL-1, TNF-α were tested by ELISA method. Differences of weight between right and left ears were measured by ear swelling method and anti-inflammation experiment.
RESULTSIn hot plate test at 90 min, pain threshold in equivalent dosage of Dinggui gel paste group was (24.87 ± 14.67) s and (15.28 ± 8.23) s in model group; (26.33 ± 15.45) s in high dosage of Dinggui gel paste group and (15.31 ± 5.02) s in model group at 120 min in hot plate test, there were no statistical differences between two groups. Pain period at stage I, licking cumulative time in high dosage of Dinggui gel paste group was (66.70 ± 22.83) s and (101.80 ± 33.65) s in model group,and had significant differences between two groups; there were statistical differences in licking cumulative time at stage I of pain period among high dosage of Dinggui gel paste group (51.30 ± 43.60)s, equivalent dosage of Dinggui gel paste group (64.00 ± 47.27) sand model group (109.50 ± 36.78) s. Content of IL-1 in model group was (28.70 ± 8.24) ng/L and (13.33 ± 2.20) ng/L in high dosage of Dinggui gel paste group, there was obvious meaning between two groups; There were significant differences in TNF-α content among model group (93.60 ± 23.65) ng/L,high dosage of Dinggui gel paste group (63.21 ± 10.54)ng/L and equivalent dosage of Dinggui gel paste group (72.69 ± 16.26) ng/L; while there were no statistical meaning in ear swelling degree among model group (5.73 ± 0.80) mg,high dosage of Dinggui gel paste group (5.42 ± 0.68) mg and equivalent dosage of Dinggui gel paste group (4.98 ± 1.52) mg.
CONCLUSIONDinggui gel paste could increase pain threshold, reduce licking accumulative time, and decrease ear swelling degree, and relief pain by regulating level of TNF-α and IL-1.

Objective:To observe the changes in percentages and subsets of invariant nature kiler T (iNKT) cells in adipose and related tissues at different stages of obesity, and analyze the role of iNKT cells during chronic inflammation in adipose tissues in a mouse model of obesity established with high-fat diet.Methods:Changes in mouse body weight, mental state, glucose tolerance and insulin tolerance were recorded. Hematoxylin and eosin (HE) staining was used to observe pathological changes in adipose tissues. Flow cytometry was performed to detect the percentages and subsets of iNKT cells as well as the percentages and subtypes of macrophages. The levels of cytokines in serum samples and the culture supernatants of lymphocytes in adipose tissues were detected with CBA. The expression of related proteins in adipose tissues was detected by Western blot.Results:(1) The volume of adipose cells increased significantly after four weeks of high-fat feeding, but the infiltration of inflammatory cells was not obvious. Significantly increased infiltration of inflammatory cells was observed after 12 weeks of high-fat feeding. (2) High-fat feeding could reduce the percentage of iNKT cells, increase the proportion of iNKT1 subgroup and decrease the proportion of iNKT10 subgroup in adipose tissues. The proportion of iNKT1 subgroup in thymus increased, but that of iNKT2 subgroup decreased. The percentage of macrophages and the proportion of M1 subgroup in adipose tissues increased, while the proportion of M2 subgroup decreased, which were more obvious after 12 weeks of high-fat feeding. (3) High-fat feeding resulted in decreased expression of E4BP4 and arginase-1 (Arg-1) in adipose tissues and increased expression of inducible nitric oxide synthase (iNOS). (4) High-fat feeding significantly increased the pro-inflammatory cytokines and decreased the anti-inflammatory cytokines in mouse serum and culture supernatants of lymphocytes in adipose tissues with more significant changes observed after 12 weeks of high-fat feeding.Conclusions:Increased iNKT1 and decreased iNKT10 in obese adipose tissues might be closely related to the increased M1 polarization and the imbalance of iNKT subsets might be involved in the progression of chronic inflammation in obese adipose tissues.

OBJECTIVETo evaluate the short term clinical results of scaling and root planning (SRP) only, SRP combined with amoxicillin (AMX) and metronidazole (MTZ) after supragingival scaling or after SRP in the treatment of aggressive periodontitis (AgP).
METHODSA total of 45 patients with AgP were randomly divided into SRP group, SRP with AMX + MTZ after supragingival scaling group and AMX + MTZ after SRP group. Subgingival scaling and root planning were performed one week after supragingival scaling and finished within 1 month. AMX and MTZ were given for 7 days immediately after supragingival scaling or the last time of SPR. Clinical examinations including probing depth (PD), attachment level (AL) and bleeding index (BI) were performed at baseline and 8 weeks after non-surgical periodontal treatment by the same examiner.
RESULTSThere were more PD reduction and AL gain in both AMX + MTZ after supragingival scaling group and AMX + MTZ after SRP group compared with SRP group [2.5 (1.8, 3.3) mm, 2.3 (1.9, 2.7) mm vs. 1.8 (1.3, 2.1) mm, P < 0.05]; [0.9 (0.5, 1.4) mm, 0.8 (0.4, 1.3) mm vs. 0.4 (0.2, 1.0) mm, P < 0.05]. In sites PD ≥ 7 mm, PD reduction was more in AMX + MTZ after supragingival scaling group than AMX + MTZ after SRP group [4.0 (3.0, 5.0) mm vs. 4.0 (3.0, 4.0) mm, P < 0.05)].
CONCLUSIONSThe combined use of AMX and MTZ during non-surgical periodontal treatment for patients with AgP was effective in short term. In patients with most sites PD ≥ 7 mm, AMX and MTZ could be taken after supragingival scaling, but the long-term clinical effects needs further investigation.

We used metabolomics to investigate the ability of a traditional Mongolian medicine called modified Tabusen-2 (MT-2) to improve kidney yang deficiency (KYD) in rats. All animal experiments were conducted under the guidance and standards of the Medical Ethics Committee of Inner Mongolia Medical University. SD rats were divided into 6 groups of six rats: a normal group, a model group, Jinkuishenqi pill administration group (1.26 g·kg-1), and MT-2 administration in high-, medium- and low-dose groups (1.512, 0.756, and 0.378 g·kg-1). KYD was established by intramuscular injection of hydrocortisone (HC) and biochemical indicators and clinical characterization was used to confirm that KYD was established. All groups received intragastrically administered drug (Jinkuishenqi pill or MT-2) or saline. Serum from each group was collected after 8 weeks and analyzed by UPLC-Q-exactive-MS to measure various biochemical indicators. The biomarkers affected by MT-2 were identified and the metabolic pathways of KYD regulated by MT-2 were analyzed by metabolomic analysis. The results show that MT-2 can decrease serum creatinine (Cr) in KYD rats and significantly increase (

OBJECTIVETo compare magnetic resonance imaging (MRI) and radiography in detecting arthropathies in patients with hemophilia.
METHODSOf 41 symptomatic joint images in the 14 patients with hemophilia, each joint was examined with both radiography and MRI within the same day. Imaging findings with both two modes were compared.
RESULTSSoft tissue swelling or joint effusion was observed in 33 joints by radiographs and in 34 joints by MRI. Joint erosions were demonstrated in 34 joints by MRI and in 20 joints by radiographs. Joint cysts were shown in 21 joints by MRI and in 9 joints by radiographs. Significant differences in the detection of erosion and cyst were found between radiography and MRI (P < 0. 05). MRI showed improvement for detecting more foci of both erosion and cyst than radiography. Bone marrow edema in 14 joints, hemorrhage in 34 joints, and synovial hypertrophy in 27 joints were revealed only by MRI.
CONCLUSIONMRI is superior to conventional radiography in detecting the abnormal changes, and should be considered as the imaging mode of choice in evaluating hemophilic arthropathies.

OBJECTIVETo elucidate whether ZFP580 is involved in the cardioprotective effects of intermittent hypobaric hypoxia (IHH) against myocardial ischemia/reperfusion (I/R) injury.
METHODSThirty two male Wistar rats were randomly divided into 2 groups (n = 16): normoxia control group and IHH preconditioning group. Rats in IHH group were exposed in a hypobaric chamber (equivalent to an altitude of 5 000 m) for a 6 h period each day for 42 d. Plasma was collected and lactate dehydrogenase (LDH) and creatine kinase-MB (CK-MB) were measured after 2 h of myocardial I/R injury. ZFP580 protein expression in myocardial tissue was assayed by Western blot. Other 8 rats in each group were used to evaluate I/R-induced cardiac infarction by TTC staining. Lentivirus-mediated gene transfection was performed in H9c2 cells 72 h prior to simulated ischemia/reperfusion (SI/R) exposure. The degree of cell apoptosis was determined by annexin V/7-AAD staining and flow cytometry analysis.
RESULTSCompared with normoxia control group, adaptation to IHH attenuated infarct size and plasma leakage of LDH and CK-MB. In addition, ZFP580 expression in the myocardium was up-regulated by IHH. The results of gene transfection showed that ZFP580 overexpression significantly inhibited cells apoptosis induced by SI/R.
CONCLUSIONOur findings demonstrate that the cardioprotective effect of IHH against I/R injury is mediated via ZFP580, a novel transcription factor, with anti-apoptotic roles in myocardial cells.
