Objective To investigate the alteration of nuclear factor kappa B( NF-κB) and tumor necrosis factor-a (TNF-α) mRNA and protein in hippocampus in chronic constrictive injury (CCI) model of rats. Methods Seventy-six male Wistar rats were randomly divided into 2 groups ( n = 38): the CCI group which received the chronic constriction injury and the sham group which received the sham operation as control. The mechanical and thermal nociceptive thresholds were assessed with paw withdrawal latency (PWL) to von Frey filaments and radiant heat at 1d before and ld,4d,7d,14d and 28d after CCI operation. Five animals were sacrificed at each time point for real-time polymerase chain reaction (real-time PCR) and another three animals sacrificed at 7d postoperation for immunofluorescence histochemical staining. Results The thresholds to mechanical and thermal stimuli decreased obviously after operation in CCI group. The expressions of TNF-α and NF-κB mRNA began to increase at ld( (2.079 ±0. 104)times and 4d( ( 1.640 ± 0.064) times) after operation and reached the peak at 7d ((2.748 ±0.147)times, (2.010 ±0.096)times) ,then the expressions of TNF-a mRNA began to decrease,while the expressions of NF-kB mRNA maintained at a high level throughout the experiment. The result of immunofluorescence histochemical staining revealed that NF-kB and TNF-α protein expressions at 7 day increased significantly on the hippocampus,which was consisted with NF-κB and TNF-a mRNA levels. Conclusion The activation NF-κB and TNF-α in hippocampus may be involved in the procession of neuropathic pain.

Background and purpose: Gap junctions(GJ) could enhance cytotoxicity induced by chemotherapeutic agents. However, whether or not GJ composed of connexin 43 (Cx43) could increase etoposide cytotoxicity remains unclear. The aim of this study was to explore the effect of GJ composed of Cx43 on etoposide cytotoxicity in testicular cancer cells. Methods: Eighteen-glycyrrhetinic acid and siRNA were used to inhibit GJ function. Retinoid acid was used to enhance GJ function.“Parachute”dye-coupling assay was used to examine dye spread through GJ composed of Cx43 in MLTC-1 cells. “Standard colony-forming assay” was used to examine cell survivals of MLTC-1 cells treated with etoposide. Results: Assayed by “parachute” dye-coupling assay, the dye spread through GJ in MLTC-1 cells was significantly decreased by 18-glycyrrhetinic acid however increased by retinoid acid. Cx43 expression and GJ function in MLTC-1 cells were inhibited by Cx43-siRNA. Results from “standard colony-forming assay” showed that etoposide cytotoxicity was decreased by 18-glycyrrhetinic acid and siRNA, however enhanced by GJ function enhancer retinoid acid. Conclusion:The function inhibition of Cx43 composed GJ in MLTC-1 cells could decrease etoposide cytotoxicity. The enhancement of GJ composed of Cx43 in MLTC-1 could increase etoposide cytotoxicity.

Objective: To understand the gender disparity and influencing factors for in-hospital mortality in patients with ST-segment elevation myocardial infarction (STEMI) at secondary hospitals in China. Methods: A total of 5525 in-hospital STEMI patients from 99 secondary hospitals of 15 provinces or autonomous regions between 2011-09 to 2014-06 were recruited including 1649 female and 3876 male. The in-hospital mortalities were compared between 2 genders and the relevant inlfuencing factors were studied by multiple Logistic regression analysis. Results: There were about 29.8% female and 70.2% male STEMI patients were studied. The in-hospital mortalities in female and male were 13.2% and 5.9%,P<0.01; gender disparity was obviously existing regardless of age, history of MI, hypertension and diabetes mellitus. The mortality in female was higher than male even without diseases history and cardiovascular risk factors. Compared with male gender, female patients were usually having elder age and likely complicated with cardiovascular risk factors; they were with lower incidence to receive ECG, drug therapy and thrombolysis within 10 minutes of admission. With adjusted confounding factors, multiple regression analysis presented that female STEMI patients had the higher mortality than male (OR:1.7, 95% CI:1.4-2.0). Conclusion: The in-hospital mortality for STEMI patients was higher in female than male at secondary hospitals in China. Female patients were usually having elder age, complicated with more cardiovascular risk factors, while with less chances to receive ECG, drug therapy and thrombolysis within 10 minutes of admission.

Objective: To analyze the current status of anticoagulant therapy for in-hospital patients with acute coronary syndromes (ACS) at county hospitals of China and to explore the relationship between anticoagulant therapy and clinical outcomes in real medical environment. Methods: 99 county hospitals from15 provinces of China were selected for this prospective registry study and 12373 eligible ACS patients without interventional therapy admitted from 2011-09 to 2014-06 were enrolled. The basic condition, previous history, initial assessment, anticoagulants (unfractionated heparin/low molecular weight heparin) application, severe bleeding events and in-hospital mortality were collected in all patients. Multiple logistic regression analysis was conducted to explore the relationship between anticoagulant therapy and clinical outcomes including in-hospital mortality, severe bleeding events and combined endpoints; meanwhile, possible confounders were adjusted. Results: A total of 9985/12373 ACS patients received anticoagulant therapy and 2388 did not. Anticoagulant therapy was conducted in 92.7% (4237/4570) patients with ST-segment elevation myocardial infarction (STEMI), 90.8% (1639/1805) with non-ST-segment elevation myocardial infarction (NSTEMI) and 68.5% (4109/5998) with unstable angina (UA); there were differences by regions and genders,P<0.01and no difference by age. Multivariable analysis indicated that anticoagulant therapy decreased the risk of in-hospital mortality in ACS patients at 53% (OR= 0.47, 95% CI 0.36-0.62), such reduction in STEMI patients was at 55% (OR=0.45, 95% CI 0.32-0.64), in NSTEMI patients was at 58% (OR=0.42, 95% CI 0.24-0.75); while it had no real effect in UA patients,P>0.05. Meanwhile, it did not increase the risk of severe bleeding events in ACS patients,P>0.05. Conclusion: Anticoagulant therapy has been widely used in STEMI and NSTEMI patients at county hospitals of China and obviously decreased the in-hospital mortality; while the application rate was relatively low in UA patients. The general safety of anticoagulant therapy has been good in ACS patients.

Objective:To test the HIV virus nucleic acid using immunoblot method (Western blotting, WB) and to follow-up with the negative and indeterminate samples in the Dujiangyan area, compare the WB and nucleic acid results before and after followed-up, and try to reduce the WB band′s false-negatives and false-positives.Methods:The 286 suspected HIV infection samples in the Dujiangyan region from January to October 2021 were confirmed by WB, the HIV virus load were tested for the samples that were WB negative and WB indeterminate, those patients were followed-up with epidemiological history and viral load results, and the results before and after tracking were compared.Results:In the 286 samples of suspected HIV infection included in this study, we reported 213 (74.48%) WB positive, 37 WB negative (12.94%), and 36 WB indeterminate (12.58%); 10 of 37 WB negative samples were followed-up; 18 of 36 WB indeterminate samples were followed-up. Among the followed-up WB negative and indeterminate samples, 17 of them had virus nucleic acid detection prior to the follow-up, and all of them turned positive after following-up. The others with no previous virus nucleic acid detection were confirmed to be negative.Conclusions:Among the followed-up samples, 2 samples were false-negative in WB negative results, and 3 were false-positive in WB indeterminate results. The viral nucleic acid must be tested and followed-up in WB negative and indeterminate samples.

Objective:To investigate the prognoses of pulmonary adenocarcinoma patients with leptomeningeal metastases (LM) and explore their influencing factors.Methods:A retrospective analysis was performed. The clinical data, imaging features and treatment plans of pulmonary adenocarcinoma patients with LM admitted to our hospital from January 2010 to June 2021 were collected. Overall survival (OS) was used as the prognostic evaluation criterion and patients were divided into good prognosis group (OS≥6 months) and poor prognosis group (OS<6 months) accordingly. Logistic regression analysis was used to evaluate the influencing factors for prognoses of pulmonary adenocarcinoma patients with LM. These patients were grouped according to different Karnofsky performance status (KPS) scores and different treatment methods, and survival curves were drawn to compare their OS.Results:A total of 173 pulmonary adenocarcinoma patients with LM were enrolled in the study, including 75 with good prognosis and 87 with poor prognosis. There were significant differences in the KPS scores, pulmonary adenocarcinoma lesion controlled status, giving third generation tyrosine kinase inhibitor (TKI) therapy or not, giving systemic chemotherapy and/or whole brain radiotherapy or not between the two groups ( P<0.05). Multivariate Logistic regression analysis showed that KPS scores and pulmonary adenocarcinoma lesion controlled status were independent influencing factors for prognoses ( OR=4.186, 95%CI: 1.583-11.070, P=0.004; OR=4.198, 95%CI: 1.499-11.760, P=0.006). Survival curves showed median OS of 8.2 months for all patients ( 95%CI: 6.5-9.8). The OS in patients with low-risk(KPS scores≥60) was significantly higher than that in patients with high-risk(KPS scores<60), that in patients accepted TKI treatment was significantly higher than that in patients not accepted TKI treatment, and that in patients accepted TKI and systemic chemotherapy was significantly higher than that in patients accepted TKI alone ( P<0.05). Conclusion:Patients with high KPS scores and controlled pulmonary adenocarcinoma can have relatively good prognosis; TKI treatment and combination therapy may prolong OS of these patients.
