The aim of this study was to explored the mechanism of inhibitory effect of chloroquine on IL-6 release induced synergistically by bacterial DNA and endotoxin. Before experiment mice were sensitized for 1 hour with D-GalN by I.P. injection. Mortality within seven days was observed after mice were challenged with CpG ODN or LPS with or without chloroquine treatment. ANA-1 cell line cells were cultivated in vitro. We investigated the influence of chloroquine on IL-6 release induced by both EC DNA and LPS. Expressions of TLR4 and TLR9 and activation of NF-?B p65 were investigated in cultured THP-1 cells pretreated with chloroquine and stimulated by EC DNA and LPS. The results showed that all mice died within 4 hours after challenged with CpG ODN and LPS. Only 4 or 5 mice pretreated with chloroquine (30mg/kg) died after challenged with CpG ODN and LPS (P

Following the increasing of amount and improving of management year by year,the management of scientific research funds must be informationized.We established an information management system of scientific research funds,according to the management standards of different departments which were the sources of funds.The system including two main modules.:budget management and expenditure management.The main functions of the system as follows:establishing the budget,expensing according to the budget,inquiring the feedback data,etc.The system increased the accuracy and effectiveness of management of scientific research funds.

Objective To study the relationship among insulin-like growth factor 1 (IGF-1), insulin-like growth factor binding protein 3(IGFBP-3) and birth weight, length and placental weight and to discuss the endocrine factors which affected fetal growth by assaying levels of IGF-1、IGFBP-3 in umbilical cord serum.Methods The neonates were divided into appropriate for gestational age infant(AGA) and small for gestational age infant(SGA) according to birth weight and gestation. The birth weight, length and placental weight of neonates were measured and at meantime the levels of IGF-1 and IGFBP-3 were assayed by immunoradiometric assay.Results 1.There were 105 neonates, including 79 AGA and 26 SGA. There were significantly statistical differences in birth weight, length and placental weight (all, P

OBJECTIVE To investigate clinical features and etiology of inhalation pneumonia.METHODS Totally 108 cases of inhalation pneumonia during from Jan 2000 to Dec 2005 were completely surveyed and analyzed. RESULTS There were underlying diseases and susceptible factors, and it was not typical in their clinical signs and symptoms.Totally 177 pathogens were isolated from sputa. There were 96 strains of Gram-negative bacilli (54.2%), 41 strains (23.2%) of Gram-positive cocci, and 40 strains (22.6%) of fungi. The 45 cases (41.7%) were with polyinfections, and 19 cases (17.6%) with double infections.CONCLUSIONS We should enhance diagnosis of inhalation pneumonia, make rational use of antibiotic, and take vigorous precautions against inhalation pneumonia.

Objective:To detect serum levels of placenta growth factor(PIGF)throughout normal pregnancy and in patients with pregnancy-induced hypertension(PIH)as well as to explore the relationship between P1GF and pathogenesis of PIH. Methods: Serum specimens were collected from 51 healthy pregnant women as a control group and 33 women suffered from PIH as third trimester of normal pregnancy(P＜0.001).There was a trend that serum levels of P1GF in PIH group decreased with the severity of PIH(P＜0.001).Conclusion:PlGF play important roles in placental angiogenesis throughout pregnancy, and decreased serum levels of PlGF is associated with PIH.

Objective: To study the examination of coronary sinus (CS) and blood flow by transthoracic echocardiography(TTE) and transesophageal echocardiography(TEE).Methods: Thirty patients with supraventricular tachycardia were studied by TTE and TEE. The CS was visualized using modified 4 chamber view. The position of the probe was optimized until the coronary sinus with its ostium into the right atrium could be visualized. CS flow recordings were performed by TEE with Doppler sample volume placed in the CS within a distance of no more than 10 mm from its ostium. Results: In all patients the angle between the doppler beam and the long axis of the CS was <30°. The CS was fully displayed in 18 patients by TTE and 28 patients by TEE. The length and width of the CS were (16.53±2.57) mm and (4.51±1.30) mm by TTE, (24.11±2.46) mm and (5.06±0.97) mm by TEE.The CS flow was characterized by biphasic flow.Its flow velocity was (39±7.8), (31±6.1) and (21±4.7) cm/s respectively. The CS flow velocity-imeintegral was(43±11.6),(43±13.0),(27±8.2) cm/s. Conclusion: Echocardiography is reliable for detecting CS and its flow. TTE is more feasible for detecting CS and its flow than TEE.

A new organic-soluble co-reactant of N,N,N’,N’-tetrakis(propyl)-pentanediamine (TPPD) was synthesized and co-immobilized with tris ( 2, 2’-bipyridine ) ruthenium ditetrakis ( 4-chlorophenyl ) borate ([Ru(bpy)3][4-(Clph)4B]2) on an indium tin oxide (ITO) electrode for electrochemiluminescent (ECL) study. The hydrophobicity of TPPD prevented its leakage from the electrode surface, thus the long-term stability of the ECL electrode was enhanced. The TPPD/[Ru(bpy)3][4-(Clph)4B]2 modified-ITO electrode exhibited strong, stable and reproducible ECL signal. The ECL signal could be quenched efficiently by phenol with a quenching efficiency of 95. 4% in the presence of 0. 1 mmol/L phenol, demonstrating the potential of the modified electrode in determination of phenolic compounds. The transient-state of the electrogenerated chemiluminescence reaction was also investigated, which revealed that the TPPD/[Ru(bpy)3][4-(Clph)4B]2 modified-ITO electrode had a longer lifetime than conventional TPA-Ru(bpy)2+3 co-reactant system.

AIM: To evaluate the efficacy of phacoemulsification and intraocular lens implantation surgical intervention of complicated cataract in patients with uveitis.
●METHODS:Retrospective study. A total of 57 cases (57 eyes ) with complicated cataract with uveitis were involved in the study from Jan. 2015 to Dec. 2015. All cases underwent phacoemulsification and intraocular lens implantation surgery successfully. The postoperative reaction, effect, complications and so on were retrospectively analyzed after phacoemulsification and intraocular lens implantation surgery. The date of visual outcome was analyzed using Non - parametric Wilcoxon test.
●RESULTS: lris were bleed in 21 eyes ( 37%) , 4 eyes ( 7%) with posterior capsule rapture and posterior chamber intraocular lens was not implanted in 4 eyes ( 7%) . The uncorrected visual acuity ( UCVA ) was significantly increased after surgery. The UCVA of 8 eyes (14%) were 0. 1 or better before surgery, and the UCVA of 42 eyes (74%) were 0. 1 or better 3mo after surgery, the difference was statistically significant ( Z=23. 42, P<0. 001). The corneal edema (17 eyes, 30%), uveitis (2 eyes, 4%) and intraocular hypertension ( 1 eyes, 2%) were appeared in postoperative 1d. The corneal edema (3 eyes, 5%) was appeared in postoperative 1wk. The uveitis ( 1 eyes, 2%) was appeared in postoperative 1mo. The corneal edema (1 eyes, 2%), uveitis (2 eyes, 4%) , intraocular hypertension ( 1 eyes, 2%) and after-cataract ( 3 eyes, 5%) were appeared in postoperative 3mo.
● CONCLUSION: The phacoemulsification combined intraocular lens implantation surgical intervention of complicated cataract in patients with uveitis has good effect and fewer complications.

Objective:To evaluate the character of cardiac valvular calcification in uremia patients and its effect on cardiac structure and function.Methods:Thirty five cases with mitral and aortic valve calcification were selected from 326 uremia patients.Control group consisted of 33 uremia patients without valvular calcification.Their age,LVEDD,LAD,AOD,LVWT,LVEF and blood pressure matched with calcification group.The observing indexs included distribution of calcification,degree of regurgitation,LVEDD,LAD,AOD,LVWT and LVEF.The observing duration was one year.Results:The results showed that characters of valvular calcification with uremia were similar to elder valvular calcification.The degree of regurgitation was more greater in calcification group than in control group after one year.The LAD was greater in calcification group after one year.Conclusion:Cardiac valvular calcification of uremia may cause the increase of regurgitation and enlarge LAD.
