Methods Following LPS or SEB was administered intraperitoneally,the expression of proliferating cell nuclear antigen(PCNA) of splenic cells and IL\|1 receptor type Ⅰ in PVN and SON were observed by using immunocytochemistry.Double fluorescent labeling technique was used to determine the relationship of IL\|1 receptor type Ⅰ co\|expressions with arginine vasopressin or oxytocin. Results 1.Compared with the controls,the expression of PCNA of mouse splenic cells was significantly enhanced by LPS or SEB ( P

Objective To investigate the clinical effect of non-steroidal anti-inflammatory drugs and αl-adrenergic antagonist on treating patients with ureteral stones.Methods A total of 128 patients with ureteral colic due to ureteral stones were randomly divided into control and treatment group,and 64 cases in each group.Both two groups were treated with tamsulosin 0.4 mg oral,intravenous injection of saline 1000 mL Patients in treatment group were received intramuscular non-steroidal anti-inflammatory drugs(10 mg) and patients in control group were received pethidine hydrochloride(10 mg).Ultrasound exam were performed after 6-8 h to evaluate the stone expulsive rate.Extracorporeal shock wave lithotripsy and other treatment were underwent when the stone was still not discharge.Results The effective rate of analgesia was 96.9％ (62/64) in treatment group and 100％ (64/64) in control group(x2 =2.03,P =0.50).The stone expulsion rate in treatment group was 28.1％ (18/64),higher than that in control group(12.5％ (8/64),x2 =4.83,P =0.05).Conclusion It is effective to relive ureteral cohc with non-steroidal anti-inflammatory drugs only,and it is better than pethidine in promote stone expulsion when they both used with α1-adrenergic antagonist.

Objective To study the expressions of IL-1 receptor type Ⅰ(IL-1RI) mRNA and IL-1? protein in the rat carotid body. Methods In situ hybridization,immunofluorescence double staining and Western blotting methods were used. Results The result of in situ hybridization showed that the positive signal of IL-1? mRNA was mainly located in the glomus cells of the carotid body.The result of immunofluorescence double staining showed that IL-1? protein also expressed in the glomus cells of the organ.The Western blotting proved that the IL-1? immunoreactive band appeared at 18kD,consistent with the molecular weight of the cytokine.Conclusion The glomus cells of the rat carotid body not only express IL-1RI mRNA,but also IL-1?.

Objective To determine whether there is correlation between intracranial and extracranial arterial stenosis in patients with ischemic stroke,and to understand the difference of the main risk factors between them.Methods One hundred and sixty-eight patients with symptomatic ischemic stroke were selected in order to analyze the correlation and risk factors of intracranial arterial stenosis and extracranial arterial stenosis.Results In the 168 cases,123 patients(73.2%)were with abnormal artery(include intimal thickening)and 100 patients(59.5%)were diagnosed with artery stenosis,including 33 cases of intracranial artery stenosis,48 cases of extracranial artery stenosis and 19 cases of intracranial and extracranial stenosis.The rate of extracranial artery stenosis(39.9%)was higher than that of intracranial artery stenosis(31.0%),but there was no significant difference between them(χ2 =2.93,P=0.11).There was no definite correlation between them(χ2 =0.35,P=0.61)and there were statistically significant differences in age and arterial pressure between patients with intracranial and mean extracranial artery stenosis(t=1.98,P=0.05;t=5.42,P<0.001),but the gender,blood pressure,blood glucose and dyslipidemia rate showed no significant difference (χ2 =1.15,3.41,0.43,0.81,P>0.05).Conclusion Extracranial arterial stenosis may not predict the possibility of intracranial arterial stenosis,and extracranial arterial stenosis may be more likely to cause ischemic stroke.

Objective: To investigate the safety and efficacy of transthoracic minimally invasive patent ductus arteriosus (PDA) occlusion in infants and young children.
Methods: We retrospectively analyzed 105 infants and young children who received the transthoracic minimally invasive PDA occlusion in our hospital from 2012-10 to 2014-10. According to PDA diameter, patients were divided into 2 groups:Group A, the patients with PDA diameter ≥ 4 mm,n=64 and group B, the patients with 2 mm ≤ PDA diameter < 4 mm,n=41. All patients received the left third parasternal intercostal incision under suprasternal echocardiography guidance. The operative effect was evaluated by transthoracic echocardiography, and the follow-up study was performed at 1 month, 3 months, 6 months period and then annually after the operation by echocardiography.
Results: All 105 patients had successfully implanted PDA occluders. The patients’ gender, age, body weight, tracheal intubation time and the in-hospital time were similar between 2 groups,P>0.05. Compared with Group B, Group A had the larger diameters of PDA (5.7 ± 1.4) mm vs (2.7 ± 0.6) mm, P<0.001, PDA occluders (10.6 ± 1.8) mm vs (7.2 ± 1.3) mm, P<0.001, and the higher rates of moderate and severe post-operative thrombocytopenia 10.9% (7/64) vs 0% (0/41),P=0.028, immediate post-operative residual shunt as 15.6% (10/64) vs 2.4% (1/41),P=0.031. There was 1 patient in Group A suffered from pericardial tamponade due to hemorrhage at 2 days after operation and he was cured by emergent pericardial drainage. The patients were followed-up for (11.6 ± 7.8) months. The 1 month post-operative residual shunt was similar between 2 groups as 1.6% (1/64 ) vs 0% (0/41),P=0.421, and there was no residual shunt at 3 months after the operation. There were no complications of occluder detachment, hemolysis, pericardial effusion, left pulmonary artery or descending aortic stenosis occurred during the follow-up period.
Conclusion: Transthoracic minimally invasive PDA occlusion is a safe and effective method to treat the relevant infants and young children, while the post-operative residual shunt and thrombocytopenia should be closely observed in patients with large PDA.

Objective: To evaluate the changes in the endoplasmic reticulum stress in the spinal cord of rats with diabetic neuropathic pain (DNP). Methods: Clean-grade healthy male Sprague-Dawley rats, aged 8 weeks, weighing 120-160 g, were fed a high-fat and high-glucose diet for 8 weeks, then diabetes mellitus was induced by intraperitoneal streptozotocin 35 mg/kg and confirmed by blood glucose level >16.7 mmol/L 3 days later.The mechanical paw withdrawal threshold (MWT) and thermal paw withdrawal latency (TWL) were measured at day 14 after injection.The establishment of DNP model was considered successful when MWT and TWL were lower than 85% of the baseline value.Fifteen rats in which the DNP model was successfully established served as DNP group, 15 rats in which the DNP model was not successfully established served as non-NDNP group (NDNP), and another 15 normal rats were selected and served as control group (group C). The MWT and TWL were measured at 3, 7 and 14 days after successful establishment of the model.The rats were then sacrificed, and the lumbar enlargement segments (L_4-6) of the spinal cord were harvested to detect the expression of inositol-requiring enzyme-1α, phosphorylated JNK (p-JNK) and Beclin1 by Western blot. Results: Compared with C and NDNP groups, the MWT was significantly decreased and the TWL was shortened at 3, 7 and 14 days after successful establishment of the model, and the expression of inositol-requiring enzyme-1α, p-JNK and Beclin1 was up-regulated in DNP group (P<0.05). Conclusion The mechanism of development and maintenance of DNP may be related to aggravated endoplasmic reticulum stress in the spinal cord and to autophagy induced by up-regulated expression of p-JNK in rats.

Objective:To compare iodine nutritional status of different populations consuming iodized salt and non-iodized salt in iodine adequate areas, and to provide a basis for formulating iodine supplementation strategies.Methods:In October 2021, Luyi County in Henan Province was selected as an iodine adequate area consuming iodized salt, while Ningling County was selected as an iodine adequate area consuming non-iodized salt. Stratified by water iodine (50 - 59, 60 - 69, 70 - 79, 80 - 89, 90 - 100 μg/L), one village was selected from each layer. One hundred children aged 8 - 10, one hundred adults, and 20 pregnant women were selected from each village to collect their urine and salt samples for testing salt and urinary iodine, and their thyroid gland was measured by ultrasound.Results:A total of 600 salt samples in Luyi County were collected, with the coverage rate of iodized salt (99.8%, 599/600) and the consuming rate of qualified iodized salt (95.5%, 573/600). A total of 1 008 salt samples in Ningling County were collected, with the rate of non-iodized salt (93.8%, 946/1 008). The median urinary iodine of children in Luyi County ( n = 240) was higher than that in Ningling County ( n = 468, 305.0 vs 232.0 μg/L, Z = - 8.10, P < 0.001). There was no statistically significant difference in median urinary iodine between pregnant women in Luyi County ( n = 120) and Ningling County ( n = 53, 240.0 vs 236.0 μg/L, Z = - 1.02, P = 0.306). The median urinary iodine of adults in Luyi County ( n = 238) was higher than that in Ningling County ( n = 486, 289.0 vs 178.5 μg/L, Z = - 11.14, P < 0.001). Children's urinary iodine ( r s = 0.21, P = 0.001) in Luyi County and adults' urinary iodine ( r s = 0.17, P < 0001) in Ningling County were positively correlated with water iodine. There was no statistically significant difference in the incidence of thyroid enlargement in children between Luyi County (0.8%, 2/240) and Ningling County (0.4%, 2/468, χ 2 = 0.80, P = 0.586), but the incidence of thyroid nodules in children in Luyi County (11.2%, 27/240) was higher than that in Ningling County (1.7%, 8/468, χ 2 = 27.36, P < 0.001). The incidence of thyroid nodules in pregnant women in Luyi County (23.3%, 28/120) was lower than that in Ningling County (46.5%, 33/71, χ 2 = 10.99, P = 0.001). There was no statistically significant difference in the incidence of adult thyroid nodules between Luyi County and Ningling County (χ 2 = 0.86, P = 0.354), with a ratio of 29.6% (71/240) to 32.9% (160/486). Conclusions:Providing population with non-iodized salt in iodine adequate areas, the overall iodine nutrition is at an appropriate level. However, children consuming iodized salt in iodine adequate areas have high level of iodine nutrition, and it is necessary to consider supplying non-iodized salt or reducing the concentration of iodized salt. Pregnant women in iodine adequate area should maintain the current policy of supplying iodized salt unchanged.
