Expressions of interleukin-6 (IL-6) and its receptor (gp80、gp130) in 8 patients with Graves' disease (GD) were compared with those in 8 euthyroid patients with nodular goiter or benign thyroid adenoma. The thyroid tissues of GD expressed significantly higher IL-6 mRNA, gp130 mRNA and IL-6 protein than those of the control group, suggesting that activated IL-6/gp130 signal pathway in the thyroid tissue may contribute to the pathogenesis of GD.

AIM:To observe the efficacy of intravitreal conbercept injection for chronic central serous chorioretinopathy (CSC).METHODS: Nine eyes of 9 patients diagnosed as chronic CSC between October 2015 to May 2016 were treated with an intravitreal injection of conbercept (0.5mg/0.05mL) (six patients were given the same does of intravitreal injection again at 1mo after the first injection).Follow-up observation was at 1, 2, and 6mo after injection.Observed indicators included best-corrected visual acuity (BCVA), intraocular pressure, optical coherence tomography (OCT), fundus fluorescein angiography (FFA), choroidal indocyanine green angiography (ICGA), macular fovea thickness (CMT), subfoveal choroidal thickness (SFCT).RESULTS:Seven of the 9 patients responded significantly to the drug, while 2 patients had no response.The CMT was 373.12±72.43μm at baseline, which decreased significantly to 332.05±67.13μm, 282.24±62.30μm and 225.56±71.08μm at 1, 2 and 6mo after the intravitreal injection.The mean thickness of SFCT was 422.11±64.82μm before treatment.The choroidal thickness of non-responsive patients before treatment was below average, respectively 353μm and 365μm.The SFCT of 1, 2, and 6mo after treatment was 391.45±75.24μm, 365.53±63.07μm, 355.40±66.65μm.Before treatment and 1mo after, there was no significant difference (P=0.074), but there was statistically significant (P<0.01) between those of before and 2mo and 6mo after.The mean BCVA of the prior treatment was 0.53±0.32, the after treatment was 0.65±0.20, there was no different between the two(P>0.05).CONCLUSION: Intravitreal conbercept injection in chronic CSC may have some effect in accelerating subertinal fluid resolution and decreasing the CMT.The SFCT within 6mo after treatment was significantly lower than pretreatment.The SFCT may be an indicator of whether patients respond.

BACKGROUND: Proximal femoral nail anti-rotation is widely used to treat various intertrochanteric fractures. Although its operation trauma is small, and the blood loss of perioperative period is still large. Tranexamic acid has been gradually used to reduce the bleeding of intertrochanteric fracture. The effectiveness and safety of reducing blood loss during perioperative period were not reported. OBJECTIVE: To explore the safety and efficacy of tranexamic acid on perioperative blood loss in patients with intertrochanteric fracture undergoing proximal femoral nail anti-rotation. METHODS: One hundred and eight patients with intertrochanteric fracture undergoing proximal femoral nail anti-rotation were selected from First Affiliated Hospital, Guangzhou University of Chinese Medicine between January 2015 and January 2017. Among all the subjects, 52 patients who received the operation before January 2016 served as the control group and 56 patients who received the operation after January 2016 were selected as the treatment group. Half an hour before operation, patients in the treatment group received 1 g tranexamic acid dissolved in 250 mL normal saline by intravenous dropping; patients in the control group just received 250 mL normal saline by intravenous dropping. The bleeding volume, blood transfusion volume, hemoglobin, hematocrit, coagulation index, D-dimer levels and complications were compared between the two groups. RESULTS AND CONCLUSION: (1) During perioperative period, actual blood loss, intraoperative blood loss, dominant blood loss, recessive blood loss, volume of drainage, blood transfusion volume and blood transfusion rate were lower in the treatment group than in the control group (P < 0.05). (2) There was no statistically significant difference in the hemoglobin and hematocrit between the two groups before operation (P > 0.05). The hemoglobin and hematocrit of the two groups gradually decreased after the operation, and there was a slight improvement in the fifth day after surgery. At postoperative 2 hours, 1, 3 and 5 days, the hemoglobin and hematocrit of the treatment group were higher than in the control group (P < 0.05). At preoperation and each time point postoperation, prothrombin time, activated partial thromboplastin time, and fibrinogen levels were not statistically significant between the two groups (P > 0.05). Postoperative D-dimer levels in the two groups were significantly higher than preoperation, and there was a return on the fifth day. There was no statistically significant difference between groups at preoperation and each time point of postoperation (P > 0.05). (3) The results suggest that the tranexamic acid can effectively reduce the dominant and recessive blood loss in patients with the intertrochanteric fracture, and it is safe and effective.

OBJECTIVETo evaluate the feasibility and efficacy of Narcotrend (NT) monitor in monitoring the depth of anesthesia in severely burned patients with target-controlled infusion (TCI) of remifentanil hydrochloride and propofol during perioperative period.

METHODSEighty patients with severe burn hospitalized from February to November 2011, to whom eschar excision was performed within one week after injury, were enrolled. They were classified into II to III grade according to the American Society of Anesthetists classification, and their total burn area ranged from 31% to 50%TBSA, or full-thickness burn area from 11% to 20% TBSA. Patients were divided into trial group (monitoring depth of anesthesia with routine method and NT monitor) and control group (monitoring depth of anesthesia with routine method) according to the random number table, with 40 cases in each group. All patients received TCI of remifentanil hydrochloride and propofol to induce and maintain anesthesia. During the operation, the anesthesia level of NT monitor used in the trial group was maintained from grade D1 to E0, while the fluctuation of mean arterial pressure (MAP) and heart rate of patients in control group was maintained around the basic values within a range of 20%, and on the basis of which, concentrations of two narcotics were adjusted. Concentrations of remifentanil hydrochloride and propofol during maintenance of anesthesia were recorded. The duration from drug withdrawal to waking from anesthesia (including the duration from drug withdrawal to eye opening by calling and the duration from drug withdrawal to orientation recovery) of patients was recorded. Values of MAP and heart rate at admission into the operation room, loss of consciousness, 2 min after intubation, before operation, 2, 15, and 30 min after the beginning of operation, and the end of operation were recorded. The prediction probability (P(k)) of NT stage (NTS) and NT index (NTI) in trial group, and that of MAP and heart rate in control group for two durations from drug withdrawal to waking form anesthesia were recorded. The administration of vasoactive drugs and intraoperative awareness of patients in two groups were recorded. Data were processed with t test, analysis of variance, and chi-square test, and the relationship between NTS, NTI, MAP, heart rate and their corresponding P(k) for the duration from drug withdrawal to orientation recovery was processed with Spearman correlation analysis.

RESULTSMaintained target effect-site concentration of remifentanil hydrochloride and target plasma concentration of propofol of patients were obviously lower in trial group [(2.62 ± 0.35) ng/mL, (3.84 ± 0.22) µg/mL] than in control group [(2.95 ± 0.21) ng/mL, (4.16 ± 0.31) µg/mL, with t values respectively -5.113 and -5.324, P values all below 0.01]. The duration from drug withdrawal to eye opening by calling and the duration from drug withdrawal to orientation recovery were obviously shorter in trial group [(10.2 ± 0.7) min, (11.1 ± 1.0) min] than in control group [(11.3 ± 1.0) min, (13.1 ± 0.7) min, with t values respectively -5.740 and -10.806, P values all below 0.01]. The MAP (except for 2 min after intubation) and the heart rate of patients in both groups were lower at the time points from loss of consciousness to the end of operation than at the time of entering operation room (with F values respectively 12.074, 36.425, P values all below 0.01 in trial group and F values respectively 21.776, 35.759, P values all below 0.01 in control group). The statistically significant difference between two groups in MAP level was only observed at the time of loss of consciousness (t = 3.985, P < 0.01). MAP level was close in two groups at other time points. Heart rates of patients in two groups were close during perioperative period. P(k) values of NTS and NTI for the duration from drug withdrawal to eye opening by calling (0.937 ± 0.025, 0.899 ± 0.049) were obviously higher than those of MAP and heart rate for this duration (0.579 ± 0.057, 0.536 ± 0.039, F = 900.337, P < 0.01). P(k) values of NTS and NTI for the duration from drug withdrawal to the orientation recovery (0.901 ± 0.031, 0.868 ± 0.046) were significantly higher than those of MAP and heart rate for this duration (0.532 ± 0.060, 0.483 ± 0.044, F = 890.895, P < 0.01). NTS, NTI, MAP, and heart rate were respectively negative, positive, positive and positive in correlation with their P(k) values for the duration from drug withdrawal to the orientation recovery (with r values from -0.734 to 0.682, P values all below 0.01). There was no statistically significant difference between two groups in administration of vasoactive drugs. No intraoperative awareness occurred.

CONCLUSIONSApplication of Narcotrend monitor in monitoring the depth of anesthesia in severely burned patients during perioperative period with TCI of remifentanil hydrochloride and propofol is beneficial to reducing dosage of narcotics and shortening duration of recovery from anesthesia, and it can accurately predict the level of consciousness of patients at the time of withdrawal of anesthesia.

OBJECTIVETo explore the associations between fasting serum lipids and high-sensitivity C-reactive protein (hsCRP).

METHODSSerum triglyceride (TG), high-density lipoprotein cholesterol (HDL-C) and hsCRP were measured in residents of Chengdu, China. Subjects with potential factors which might influence lipids and hsCRP were excluded, 580 subjects [mean age (62.3 ± 6.6) years; male: 58.7%] were finally recruited by random sampling methods.

RESULTSThere was a weak positive relationship between TG and hsCRP (r = 0.108, P = 0.01) and a weak negative relationship between HDL-C and hsCRP (r = -0.197, P < 0.001), this was also true in the sub-group with BMI < 24 kg/m(2) (r = 0.236, -0.140 respectively, all P < 0.001). In subjects with BMI < 24 kg/m(2), the hsCRP concentration was significantly higher in subjects with higher TG or lower HDL-C (all P < 0.05). hsCRP increased in proportion with the degree of dyslipidemia. After adjusting for gender, age, TC, LDL-C, fasting blood glucose, systolic blood pressure, diastolic blood pressure, history of hypertension and diabetes, smoking and alcohol drinking, logistic regression analysis showed that the odds ratio for increased hsCRP was 1.970 in subjects with either increased TG or lower HDL-C (P = 0.105) and 9.098 in subjects with both higher TG or lower HDL-C levels (P = 0.031). However, the observed relationship between TG, HDL-C and hsCRP in subjects with BMI < 24 kg/m(2) could not be observed in subjects with subjects with BMI > 24 kg/m(2) despite significant more cardiovascular risk factors in these subjects.

CONCLUSIONSA weak positive correlation between TG and hsCRP as well as a weak negative correlation between HDL-C and hsCRP was evidenced in the whole cohort suggesting dyslipidemia might be related to enhanced inflammatory status. However, this relationship is not observed in subjects with BMI > 24 kg/m(2) despite existence of more cardiovascular risk factors in these subjects.

Objective To identify heart failure(HF) symptom clusters and their transformation through the progress of disease. Methods A convenient sample of 200 HF patients were recruited in this longitudinal study. The Chinese version of Memorial Symptom Assessment Scale-Heart Failure(MSAS-HF) was used to collect data before admission,3 months after discharge,and 6 months after discharge. At each time point,symptoms with incidence rate above 15% were chosen for cluster analysis. Results HF symptoms before admission were divided into 4 clusters:emotional and digestive cluster,ischemic cluster,weary cluster,and congestive edema cluster. Symptoms at 3 months after discharge and 6 months after discharge fell into 2 clusters:sickness cluster and weary cluster. Dry mouth was not included in either clusters. Conclusion The distribution and structure of HF symptom clusters had changed a lot at different stages of disease. It suggests that pertinent interventions might be taken according to the pattern of changes of HF symptom clusters through the progress of the disease.

Objective:To investigate the effect of inhibiting of HOXB7 gene expression on proliferation and apoptosis of colon cancer cells.Methods:The synthetic negative control siRNA (negative control group) and HOXB7-siRNA (HOXB7 transfection group) were transfected into human colon cancer SW480 cells by LipofectamineTM2000 liposome mediated method,untreated cells as blank group.RT-PCR and Western blot were used to detect the mRNA and protein expression of HOXB7 after transfected 48 h respectively;cell proliferation was detected by CCK8 assay after transfected 24,48,72,96 h;cells apoptosis was detected by flow cytometry after transfected 48 h;the expression of apoptosis related proteins Bcl-2,Bax and Notch1 signaling pathway Notch1 and Hes1 were detected by Western blot.Results:The mRNA and protein expression of HOXB7 in HOXB7 transfected group was significantly lower than that in blank group(P<0.05);OD value was no statistical significance in the three groups after transfected 24 h(P>0.05), while after transfected 48,72,96 h,compared with the control group,OD value in HOXB7 group was significantly decreased(P<0.05);compared with the blank group,the apoptosis rate in HOXB7 transfection group increased significantly,and the expression of Bcl-2, Notch1 and Hes 1 proteins was down regulated,and the expression of Bax protein was up-regulated(P<0.05).Conclusion:RNA inter-ference in the expression of HOXB7 gene in colon cancer can inhibit the proliferation of cancer cells and induce apoptosis by inhibiting of the Notch1 signaling pathway.

The study was aimed to investigate the effects of emodin on the proliferation and apoptosis of adriamycin-resistant HL-60/ADR cells, and to explore the underlying mechanism. The cell viability and colony formation were detected by MTT assay and colony formation assay respectively. Apoptotic cells were tested by means of cell cycle analysis, mitochondrial transmembrane potential levels, caspase-3 activity detection, Annexin V FITC/PI staining and TUNEL labeling. RT-PCR was used to analyze the bcl-2 and c-myc mRNA expressions. The protein expressions of Bcl-2, c-Myc and caspase-3 precursor were determined by Western blot. The results showed that HL-60/ADR cell growth was significantly inhibited by emodin in dose and time dependent manners. Cell colony formation obviously decreased with IC50 5.79 micromol/L. G0/G1 phase cell population increased while G2/M phase cells decreased in 40 and 80 micromol/L groups compared with control group (p < 0.01), and no significant difference of cell cycle was observed in 20 micromol/L group (p > 0.05). The typical hypo-diploid peak (apoptotic peak) appeared in each dose group. The levels of mitochondrial transmembrane potential of HL-60/ADR cells decreased and caspase-3 activity increased when incubated with emodin for 12 and 24 hours respectively. Apoptosis occurred in a dose-dependent manner, and its earlier and later stages were identified by Annexin-V FITC/PI staining and TUNEL labeling methods respectively. The expressions of bcl-2, c-myc mRNA and Bcl-2, c-Myc, caspase-3 precursor protein were all down-regulated in a time-dependent manner after treatment with emodin at different times. It is concluded that emodin efficiently inhibits growth and induces apoptosis on HL-60/ADR cells, which may be related with the down-regulation of mitochondrial transmembrane potential and expressions of bcl-2 and c-myc, as well as up-regulation of caspase-3 activity.
