Objective To compare the computed orthopantomography(COPT)with Sh?ller radiography(SR),film orthopantomography(FOPT)and other traditional radiographic techniques in the radiography of temporomandibular joint(TMJ).Methods Ninty-eight cases were randomly divided into 3 groups,and the open and close positions of TMJs of both sides were examined with SR,FOPT,and COPT, respectively.The satisfactory rates of the X-ray pictures were statistically analyzed with Pearson chi-square in SPSS10.0,and the satisfactory rates were analyzed with q test between the groups.Results One hundred and forty-four of the open and close positions of 144 TMJ pictures of the COPT group,128 of 128 of the FOPT group,and 6 of 120 of the SR group were satisfactory in the mandible ramus of the TMJ,with satisfactory rate being 100%,100%,and 5%,respectively(P0.01),respectively between FOPT and COPT groups.The difference was not statistically significant.The exposure was as follows:COPT,99—113 mAs;FOPT,210—225 mAs;and SR,48—75 mAs.Therefore,COPT and FOPT were superior to SR in the pictures of the mandible ramus,coronoid process,and incisure,but inferior in the joint space pictures.The satisfactory rates of the condylar process and articular tubercle were same in the 3 groups.The exposure of the FOPT group was greater than that of the COPT and SR groups.Conclusion COPT is superior to SR and FOPT in TMJ radiography,and should be applied widely in the clinic.

AIM: To study the effect of Ginkgo biloba extract (GbE) on the expression of connective tissue growth factor (CTGF) in the initiating stage of pulmonary fibrosis of rats after administration of bleomycin (BLM).METHODS: The expression of CTGF in lungs was detected by Western blotting. The content of hydroxyproline was assayed by the method of chloramines T. The content of malondialdehyde (MDA) in plasma was investigated by colorimetry.RESULTS: On day 14 after administration of BLM, the contents of CTGF in lungs and MDA in plasma in BLM+NS group were higher than those in NS group, respectively (P

The role of interleukin-17 (IL-17) in autoimmune hepatitis (AIH) was investigated. A mouse model of experimental autoimmune hepatitis was established, and the syngeneic S-100 antigen emulsified in complete Freud's adjuvant was injected intraperitoneally into adult male C57BL/6 mice. The IL-17 expression in serum and the livers of the mice models was detected by using ELISA and immunohistochemistry, respectively. IL-17 neutralizing antibody was used to study the biological effect of IL-17 in the experimental AIH. IL-17 neutralizing antibody in vivo administration alleviated the hepatic inflammation and ALT level in the AIH model. IL-17 in the peripheral blood mononuclear cells (PBMC) of AIH patients was measured by using real-time PCR method. The results showed that IL-17 level was significantly up-regulated in AIH patients and mice models. It was concluded that IL-17 contributed to the development of AIH and might be a potential therapeutic target of AIH.

Objective To explore the effect of Zhengu Pills ( a kidney-tonifying and blood-activating Chinese medicine) and Guci Fengshi Pills ( a dampness-dispelling and blood-activating Chinese medicine) on bone remodeling of cell model in vitro. Methods MC3T3-E1 and RAW264.7 cells were differentiated into osteoblasts ( OB) and osteoclasts ( OC) after stimulated by different inductive agents respectively, and then OB and OC were co-cultured. Immunocytochemical staining was applied to identify the construction of co-cultured OB and OC system. The serum containing corresponding medicine was prepared after the rats were given intragastric administration of Diacerein, Zhengu Pills and Guci Fengshi Pills. And then the obtained serum was used for treatment of co-cultured cells separately. At the end of experiment, Western blotting and real-time polymerase chain reaction (PCR) tests were carried out. Results The osteoprotegerin (OPG) expression was increased and gene expression of glycoprotein 130 (gp130) was decreased in co-cultured cells after treatment with the serum containing Zhengu Pills and Guci Fengshi Pills ( P<0.05) . Conclusion Zhengu Pills and Guci Fengshi Pills have therapeutic effects on osteoarthritis ( OA) by inhibiting the bone resorption function of OC by the down-regulation of gp130 and by enhancing bone formation and increasing the bone density through recombinant murine’s RANK ligand (RANKL) -RANK-OPG system.

Objective To observe and evaluate the predictive value of electroencephalogram (EEG) abnormalities of the EEG monitoring of patients with brain dysfunction in the intensive care unit (ICU).Methods Total of 58 cases with brain dysfunction under EEG were collected from the ICU of the XiangYa Hospital,Central South University from January 2014 to December 2015.EEG was performed to monitor those patients and data was collected,analyzed and classified according to both Synek and Young EEG scales to evaluate its predictive value.The statistical analysis was performed with SPSS 23.0 software (MAC,USA) and statistical significant was considered as P ＜0.05.Numerical values were given as means ± SD and t-test was performed to compare data of different groups.Kaplan-Meier survival estimator was used to draw the survival curve,and the survival analysis was postulated by COX regression analysis.Results Data from 58 patients were collected and classified according to both Synek and Young EEG scales,positive waveforms as periodic discharge or delta-predominant background were found among 50 patients,electrographic seizures were found in 7 patients,patients with EEG abnormality possessed a high level of SI00β and showed statistical differences.The 28-day mortahty was independently associated with Acute Physiology and Chronic Health Evaluation (APACHE]] score) (OR:1.08;95％ CI [1.03 to 1.14])、Synek Grade ＞2 (OR:0.17;95％ CI [0.03 to 0.80])、electrographic seizures (OR:23.70;95％ CI [2.02 to 277.73]) and slow rhythm (OR:8.54;95％ CI [1.72 to 42.32]).Conclusions The 28-day mortality of patients under EEG with brain dysfunction was independently associated with Synek Grade ＞ 2,electrographic seizures and slow EEG rhythm.

This study was aimed to establish a stable animal model of left ventricular hypertrophy (LVH) to provide theoretical and experimental basis for understanding the development of LVH. The abdominal aorta of male Wistar rats (80-100 g) was constricted to a diameter of 0.55 mm between the branches of the celiac and anterior mesenteric arteries. Echocardiography using a linear phased array probe was performed as well as pathological examination and plasma B-type natriuretic peptide (BNP) measurement at 3, 4 and 6 weeks after abdominal aortic constriction (AAC). The results showed that the acute mortality rate (within 24 h) of this modified rat model was 8%. Animals who underwent AAC demonstrated significantly increased interventricular septal (IVS), LV posterior wall (LVPWd), LV mass index (LVMI), cross-sectional area (CSA) of myocytes, and perivascular fibrosis; the ejection fraction (EF), fractional shortening (FS), and cardiac output (CO) were consistently lower at each time point after AAC. Notably, differences in these parameters between AAC group and sham group were significant by 3 weeks and reached peaks at 4th week. Following AAC, the plasma BNP was gradually elevated compared with the sham group at 3rd and 6th week. It was concluded that this modified AAC model can develop LVH, both stably and safely, by week four post-surgery; echocardiography is able to assess changes in chamber dimensions and systolic properties accurately in rats with LVH.

OBJECTIVETo investigate the significance of clinicopathological stage of chronic idiopathic myelofibrosis (CIMF) in WHO classification of 2001.

METHODSHistopathological analysis of bone marrow biopsy plastic-embedded sections stained with H-G-E and Gomori's stains and clinical features of 113 cases previously diagnosed as primary myelofibrosis (PMF) and 48 cases MPD-U (total of 161 cases which including male 79 and female 82) were studied retrospectively.

RESULTSThere was no significant differences on the clinical features among the cellular phase, collagen fiber phase, sclerotic phase and osteomyelosclerosis of 113 previously diagnosed patients. According to WHO classification 2001 of CIMF, previously diagnosis in 48 cases with MPD-U was WHO pre-CIMF, and in 113 cases with PMF was WHO CIMF-Fs. There were significant differences between of WHO pre-CIMF and WHO CIMF-Fs about clinicopathological features except age. The percentage of immature granulocytes, normoblasts, lymphocytes in peripheral blood, the size of hepatosplenomegaly, and the percent age of tear drop-like red blood cells in pre-CIMF were significantly lower than those in CIMF-Fs (P < 0.05). However, the number of hemoglobin and platelets in patients with pre-CIMF were significantly higher than that with CIMF-Fs (P < 0.01).

CONCLUSIONpre-CIMF and CIMF-Fs in clinical and histopathological features were different development stage of CIMF, while osteomyelosclerosis is a variant of CIMF, but not an independent disease.

The results of previous studies on the menstrual-related sleep changes were inconsistent. The menstrual-related circadian sleep-wake and rest-activity rhythms changes are still uncertain. Using actigraphic monitoring of wrist activity, we investigated the sleep-wake and rest-activity patterns of 12 normally cyclic healthy women during reproductive life. Multivariate analyses were performed during the four phases of the menstrual cycle: menstrual phase (lst to 5th day of menstrual cycle), late follicular/peri-ovulation phase (11th to 15th day), early to mid luteal phase (18th to 23rd day) and late luteal phase (25th to 28th day), respectively. The variables of circadian sleep-wake pattern were similar in the four phases, except an increased tendency of the sleep latency in peri-ovulation phase compared with the early to mid-luteal phase (19+/-18 vs 9+/-6), but unfortunately no statistical significance were found (P<0.10). Concerning the circadian patterning of rest and activity, the interdaily stability (IS) in menstrual phase was significantly higher than the early to mid luteal phase (P<0.05). In early to mid luteal phase, the M10 onset time was significantly earlier compared with that of the late follicular/peri-ovulation phase (P<0.05), and the cosinor peak time was significantly earlier compared with that of the late luteal phase (P<0.05). The circadian periodogram calculated the period length of the rhythm of average woman. The average length was (24.01+/-0.29) h, and there was no significant difference among the four menstrual phases. The results suggest that the phase of circadian rest-activity rhythm may be modulated by the menstrual cycle, but the quantity and quality of the rest-activity rhythm have no essential different, and that menstrual cycle may have no effects on the circadian sleep-wake rhythm in normally cyclic healthy women.

OBJECTIVE: To compare several noninvasive indices of fibrosis in chronic viral hepatitis B, including liver shear-wave velocity (SWV), hyaluronic acid (HA), collagen type IV (CIV), procollagen type III (PCIII), and laminin (LN). MATERIALS AND METHODS: Acoustic radiation force impulse (ARFI) was performed in 157 patients with chronic viral hepatitis B and in 30 healthy volunteers to measure hepatic SWV (m/s) in a prospective study. Serum markers were acquired on the morning of the same day of the ARFI evaluation. Receiver operating characteristic (ROC) analysis was performed to evaluate and compare the accuracies of SWV and serum markers using METAVIR scoring from liver biopsy as a reference standard. RESULTS: The most accurate test for diagnosing fibrosis F ≥ 1 was SWV with the area under the ROC curve (AUC) of 0.913, followed by LN (0.744), HA (0.701), CIV (0.690), and PCIII (0.524). The best test for diagnosing F ≥ 2 was SWV (AUC of 0.851), followed by CIV (0.671), HA (0.668), LN (0.562), and PCIII (0.550). The best test for diagnosing F ≥ 3 was SWV (0.854), followed by CIV (0.693), HA (0.675), PCIII (0.591), and LN (0.548). The best test for diagnosing F = 4 was SWV (0.965), followed by CIV (0.804), PCIII (0.752), HA (0.744), and LN (0.662). SWV combined with HA and CIV did not improve diagnostic accuracy (AUC = 0.931 for F ≥ 1, 0.863 for F ≥ 2, 0.855 for F ≥ 3, 0.960 for F = 4). CONCLUSION: The performance of SWV in diagnosing liver fibrosis is superior to that of serum markers. However, the combination of SWV, HA, and CIV does not increase the accuracy of diagnosing liver fibrosis and cirrhosis.
