OBJECTIVETo develop a life quality scale suitable for idiopathic pulmonary fibrosis (IPF) patients, objectively reflecting its changes.

METHODSAuthors first put forward a theoretical structure model of a scale according to patient-reported outcome (PRO) scale formulation principle by combining basic theories of Chinese medicine (CM). Then authors developed an initial scale on the basis of various life quality scales for respiratory disease patients by using structural decision making. Totally 34 patients with confirmed diagnosis of IPF were tested by questionnaire. Items were screened using expert importance scoring method, factor analysis, correlation coefficient method, Cronbach's alpha coefficient method. IPF patient reported outcomes (IPF PRO, IP) were finally defined.

RESULTSA new IP scale was developed covering three areas and 38 items. Pearson correlation coefficient for correlation analysis of clinical symptom scores in ST-George Respiratory Questionnaire and IP scale was 0.828 (P < 0.01). Pearson correlation coefficient for correlation analysis of activity ability scores was 0.929 (P < 0.01). Pearson correlation coefficient for correlation analysis of total scores was 0.862 (P < 0.01). By reliability of IP scale itself (reliability) analysis, Cronbach's alpha coefficient was 0.713. By using factor analysis method for data analysis, KMO statistics was 0.902.

CONCLUSIONIP scale fully reflected the connotation of IPF patients' quality of life, so it could be used as CM clinical therapeutic effect evaluation tool.

Objective To investigate the effects of three procedures for hysterectomy.Methods The clinical characteristics of 370 cases who respectively received hysterectomy by total transabdominal hysterectomy(TAH,150 cases),transvaginal hysterectomy(TVH,120 cases),or laparoscopically assisted vaginal hysterectomy(LAVH,100 cases)were analyzed and their effects and outcomes and the expenses for medical treatment were compared from 2000 January to 2005 December.Results The average operation time of TAH,TVH and LAVH was(78?28) minutes,(102?35)minutes,(119?28)minutes respectively.The average operation time of TAH was significantly shorter than that of TVH and LAVH groups(P＜0.01).The volume of hemorrhage during operation in TAH group was less than that of other two groups significantly[TAH(53?29)ml,TVH(110?35)ml,LAVH(93?50 )ml](P＜0.01).The average time of bowel function recovery in TAH group[(42?7)hours]was significantly longer than that of TVH[(23?5)hours]or LAVH[(25?4) hours]groups(P＜0.01).The average hospital stay after opera- tion in TAH[(8.9?1.1)days]group was significantly longer than that of TVH[(5.7?2.4)days]or LAVH [(6.3?1.9)days] groups(P＜0.01).The average expenses for medical treatment in LAVH[(7273?938)yuans] group was significantly more than that of TAH[(5594?308)yuans]or TVH[(5450?167)yuans]groups(P＜0.01).But the lesion and the complication after operation of three groups had no difference.Conclusion Different procedures for total hysterectomy have their own advantage and disadvantage.The operation procedure must take ac- count of the economy,echnique of medical treatment and the condition of the hospital.

Objective To assess the diagnostic value of delayed CT contrast enhancement patterns in hilar cholangiocarcinoma based on two phased dynamic incremental CT scanning. Methods Fifty two patients with suspected hilar tumor and bile duct obstruction underwent spiral CT scan. The scan time for one revolution of the X ray tube was 1 second. To elucidate the delay time for optimal imaging, all proved cholangiocarcinoma with delayed (6、8、10、15、20、30 minutes) post equilibrium phase contrast enhanced CT scans were acquired with unenhanced, dynamic contrast enhanced, and delayed images. Degree of delayed enhancement was compared with that of surrounding liver parenchyma. Results (1) 8～15 minutes after IV injection of contrast material was the delay time for optimal imaging. (2) Of 29 cholangiocarcinomas, the early CT showed hypoattenuating (lower than that of liver parenchyma) in 23 tumors, isoattenuating (equal to that of the liver) in 4 tumors, and hyperattenuating (higher than that of liver) in 2 tumors. The delayed CT scan showed isoattenuating in 8 tumors, hyperattenuating in 21 tumors, and no hypoattenuating. Most of delay imaging of hilar cholangiocarcinoma may appear hyperattenuating ( U=-4.307 3, P

Posterior capsular opacification (PCO) is the most common complication that leads to loss of vision after cataract surgery.Neodymium doped:Yttrium-Aluminum-Garnet (Nd:Yag) laser capsulotomy is a common treatment for PCO, but still associated with several complications.In the past decades, the prevention and treatment of PCO have always been a hot spot of research in ophthalmology.This review will address the advances in the prevention and treatment of PCO in the aspects of surgical techniques and types of intraocular lens (IOL).

Objective To investigate signal transduction mechanism of phospholipase C?1 (PLC?1) in colorectal cancer cells. Methods Gel electrophoresis mobility shift assay (EMSA), immunocytochemistry, zymography and RT-PCR were performed to investigate the function of PLC?1 on nuclear factor-Kappa B (NF-?B), matrix metalloproteinase-2 (MMP-2) and tissue inhibitor of metalloproteinase-2 (TIMP-2) in LoVo cell. Results Compared with control group, nuclear positive rate of cells treated with epidermal growth factor (EGF) increased significantly (from 26.91%?2.84% to 40.83%?4.36%), while that of cells treated with 2.5mol/L U73122 decreased to 12.20%?1.89%. Meanwhile, pretreatment with 2.5mol/L U73122 before EGF treatment decreased nuclear positive rate of cells from 40.83%?4.36% to 18.21%?1.34%. The results of EMSA further verified that PLC?1 can regulate the activity of NF-?B. RT-PCR results showed that EGF, PLC?1 or NF-?B had no significant effect on the expression of MMP-2, TIMP-2 at mRNA level. Furthermore, zymography indicated that the activity of MMP-2 did not change dramatically by EGF, PLC?1 or NF-?B. Conclusion These data suggested that EGF-PLC?1-NF-?B signaling pathway was operative in LoVo cell, but MMP-2 and TIMP-2 may not be regulated by EGFR-PLC?1-NF-?B signaling pathway.

OBJECTIVETo study the differences in the toxicity of vinegar-processed Kansui Radix on normal and cancerous ascites model rats.

METHODNormal and cancerous ascites model rats were taken as the research objects and orally administered with different doses of vinegar-processed Kansui Radix for 7 d. Pathological sections were prepared to observe the damages in liver, stomach, intestinal tissues in rats and detect the impacts on serum, liver, stomach and intestinal tissues and the oxidative damage index.

RESULTCompared with the blank group, all of normal administration groups and model groups showed significant damages in liver, stomach and intestinal tissues. Compared with the model groups, all of normal administration groups revealed notable alleviation in damages. Compared with the blank group, the model groups showed significant increases in AST, ALT and MDA in serum and liver (P < 0.01) and a significant decrease in GSH in serum and liver, stomach, intestinal tissues (P < 0.01). Compared with the blank group, the results showed significant decreases in ALT, AST in serum and ALT in liver in model low, medium and high dose groups and AST activity in liver tissues in the normal high dose group (P < 0.05, P < 0.01); significant decreases in GSH in serum and stomach tissues in normal low, medium and high dose groups and GSH content in liver and intestinal tissues in normal medium and high dose groups (P < 0.05, P < 0.01); notable rises in MDA in liver tissues in normal low, medium and high dose groups and MDA content in serum and stomach and intestinal tissues in normal medium and high dose groups (P < 0.05, P < 0.01). Compared with model groups, data revealed significant decreases in ALT, AST in serum in model low, medium and high dose groups, AST in liver tissues of model medium and high dose groups and ALT activity in liver in the model high dose group (P < 0.05, P < 0.01); significant increases in GSH content in serum and stomach tissues of model low, medium and high dose groups, GSH in liver tissues in model medium and high dose groups and GSH in intestinal tissues in the high dose groups (P < 0.05, P < 0.01); and notable declines in MDA content in serum in model low, medium and high dose groups, MDA in liver tissues of model medium and high dose groups and MDA in stomach and intestinal tissues the high dose group (P < 0.05, P < 0.01).

CONCLUSIONAccording to the study, vinegar-processed Kansui Radix showed a significant lower toxicity liver, stomach, and intestines of cancerous ascites model rats, which provided a basis for clinical safe application of vinegar-processed Kansui Radix based on symptom-based prescription theory.

Objective: To evaluate the association between autoimmune diseases (ADs) and thyroid dysfunction using a Mendelian randomization (MR) approach. Methods: Genetic predictors of hypothyroidism and hyperthyroidism were collected through the UK Biobank, including 337 159 individuals and 10 894 596 single nucleotide polymorphisms (SNPs). Genetic predictors of 6 ADs including systemic lupus erythematosus (SLE), ankylosing spondylitis (AS), type 1 diabetes mellitus (T1DM), rheumatoid arthritis (RA), primary biliary cholangitis (PBC), and multiple sclerosis (MS) were collected through the GWAS Catalog database, including 14 267 individuals and 7 071 163 SNPs, 22 647 individuals and 99 962 SNPs, 24 840 individuals and 12 783 129 SNPs, 58 284 individuals and 13 108 512 SNPs, 13 239 individuals and 1 124 241 SNPs, and 38 589 individuals and 156 632 SNPs. MR analysis was performed using the inverse-variance weighted (IVW) method. The horizontal pleiotropy was assessed using the MR-Egger regression, and sensitivity analysis was conducted with the leave-one-out. Results: IVW results showed that a higher risk of hypothyroidism was associated with T1DM (OR=1.007, 95%CI: 1.003-1.011, P<0.05), SLE (OR=1.005, 95%CI: 1.002-1.009, P<0.05), and RA (OR=1.013, 95%CI: 1.009-1.016, P<0.05); a higher risk of hyperthyroidism was associated with T1DM (OR=1.002, 95%CI: 1.001-1.003, P<0.05) and SLE (OR=1.002, 95%CI: 1.001-1.003, P<0.05). Conclusions Genetically predicted ADs are associated with an increased risk of thyroid dysfunction. A higher risk of hypothyroidism is associated with T1DM, SLE and RA; a higher risk of hyperthyroidism is associated with T1DM and SLE.

Objective To investigate the maturation status of monocytes and their responses to the stimulation of toll like receptor (TLR) ligands during primary HIV-1 infection, and to further understand the correlation between functional status of monocytes and disease progression during primary HIV -1 infection. Methods Peripheral blood mononuclear cells ( PBMCs) were collected from 35 subjects with primary HIV-1 infection and 13 HIV-negative healthy subjects to isolate monocytes .Monocytes were stimulated with LPS and Pam3CSK4, respectively, and cultured for 20 hours.The expression of activaion/inhibitory markers on monocytes were analyzed by flow cytometry before and after stimulation .The secretion of proinflammatory cy-tokines ( IL-1β, TNF-αand IL-6) by stimulated monocytes were detected by ELISA .Results The expres-sion of activation markers CD80, CD86, CD40 and inhibitory marker PD-L1 on monocytes were increased in subjects with primary HIV-1 infection (P<0.001 except for CD86 P=0.01).The level of CD40 was posi-tively correlated with viral load in plasma (P<0.001, R=0.553).Compared with control group, primary HIV-1 infection group showed a less increase in the expression of HLA-DR, CD80, CD86 and PD-L1 on monocytes after stimulation with LPS and Pam3CSK4 (P<0.001), but the secretion of proinflammatory cyto-kines TNF-α(LPS:P=0.004, Pam3CSK4:P=0.012) and IL-6 (LPS:P=0.006) were enhanced in mono-cytes from patients with primary HIV-1 infection.Conclusion Monocytes were activated during primary HIV-1 infection.They secreted higher level of proinflammatory cytokines after stimulation with TLR ligands , indicating monocytes might play a role in microbial translocation and immune activation during HIV -1 infection .
