Objective To assess the long term effects of combined oral contraceptive pills use on the mean of serum TG, TC, HDL C, LDL C, ApoA1, ApoB and Lp(a). Methods The study was carried out in 446 women grouped as combined norethisterone containing ethinylestradiol (EE) 35 ?g and norethisterone 625 ?g; combined 18 metayl norethisterone (norgestrel) containing EE 30 ?g and 18 metayl norethisterone 300 ?g for using 5～25 years, and control subjects wearing IUD for the corresponding period. The three groups were similar in age, body mass index (BMI), continued period of contraceptives use and income. Results The data showed that changes of varying degree of lipid and lipoprotein parameters were obvious in women of long term taking low dose combined norethisterone and norgestrel, compared with the control. The mean of TG, HDL C, ApoA1 were significantly increased simultaneously ( P

AIM To explore the radioprotective function of Xihuang Capsules (Bovis Calculus artijactus,Moschus,Olibanum,Myrrha) in patients with acute radiation-induced oral mucositis and its mechanisms.METHODS Eighty patients with nasopharyngeal carcinoma undergone radiotherapy were randomized into two groups:treatment group (radiation plus Xihuang Capsules) and control group (radiation alone).The comparison of two groups in the onset and the tolerated dose of mucositis was made according to the acute radiation injury classification standard.The levels of TNF-α and IL-6 in saliva were detected by ELISA.RESULTS After the treatment with Xihuang Capsules,the onset of oral mucositis delayed significantly and the tolerated dose elevated markedly comparing with the control group (t =2.180,12.930,P ＜ 0.05).The morbidity rate of Ⅲ-N-degree of oral mucositis in the treatment group was lower than that of the control group at the dosage of 40 Gy and 70 Gy,respectively (Z =3.661,4.270,P ＜0.01).Furthermore,there was no difference in the levels of TNF-α and IL-6 in the pre-treatment in the two groups (t =1.010,1.469,P ＞ 0.05).With the increase in radiant dose,the levels of TNF-α and IL-6 in the two groups both elevated dramatically,and peaked at the dose of 40 Gy,but both levels in the treatment group were lower than those of the control group (t =8.305,6.069,P ＜ 0.05).When DT =70 Gy,the levels of TNF-α and IL-6 were lower than pre-radiation,and the levels of TNF-α and IL-6 in the treatment group were lower than those in the radiation alone group (t =3.835,2.488,P ＜ 0.05).CONCLUSION Xihuang Capsules can delay and reduce acute radiation-induced oral mucositis and improve radiation tolerated dose,so it may involve the release of TNF-oα and IL-6 in saliva.

Objective:To study the impact of rotary cell culture system(RCCS) on the quality and activity of fetal islets of pancreas after cryopreservation and resuscitation.Methods:The fetal islets of pancreas were assigned into three groups averagely,experiment group 1,2 and control group.In experiment group1 and 2,fetal islets of pancreas were cultivated in RCCS and common culture respectively.While in control group,fresh fetal islets of pancreas were cultivated in RCCS all the time.We resected the fetal pancreas and digested with Collagenase V and purified with ficoll solution.Then standard cryopreservation step was adopted,and after resuscitation,the islets of pancreas were cultivated continuously.And the quantity,quality and activity of the islets of pancreas,and insulin stimulation test results in all groups were detected.Results:After purification,islets got from one fetal pancreas reached 2,331.98-5,115.43 IEQ(average 3,551.27? 253.76 IEQ) .The survival rate,the insulin release and stimulation index in islets of pancreas of group 1 incubated in RCCS were higher than those in common culture.Conclusion:RCCS are good for the growth and proliferation of islets of pancreas,and the islets of pancreas cultivated in RCCS have better insulin secreting capacity.RCCS combined standard cryopreservation method may further improve the cryopreservation effect.

Objective To explore the correlation between cytomegalovirus pneumonia (CMV-IP) and viral load in renal transplant recipients and to find out the threshold value of viral load for predicting CMV-IP. Methods The blood samples of 56 renal transplant recipients were taken weekly for the first 2 months and every 2 weeks for 2-6 months after transplantation.Real-time PCR were used to quantify the plasma CMV DNA.The mean viral loads of CMV-IP group and non-CMV-IP group in each time were compared using Wilcoxon test.Different cut-off values were tested to find the suitable values to predict the CMV-IP. Results Of the 56 recipients,8 (14.3%) developed CMV-IP.The viral loads were near zero in the first 4 weeks in both groups;from week 5 the viral load of CMV-IP group increased gradually and reached the climax at week 8 and then declined,but the load of non-CMV-IP group fluctuated at a low level.During weeks 5-11,the viral loads of CMV-IP group were higher than those of non-VMV-IP group.At 5,7 and 9 weeks,the differences of the viral loads between the 2 groups were significant (P

Objective To evaluate a new TNM staging system inclusive of intraperitoneal free cancer cells in terms of postoperative survival of patients with gastric cancer. Methods Free cancer cells (FCC) in the peritoneal washes of gastric cancer patients were estimated by measuring CEA mRNA levels using real-time RT-PCR. After 5-year follow-up, we get the cut-off value of CEA mRNA level by using MedCalc software to analyze the ROC curve. When CEA levels are more than the cut-off value, it may considered as FCC(+), and then using FCC(+) as distant metastasis (MI) to make a new TNM staging and analyze patients life-span. Results (1) Under the ROC curve analysis, when the cut-off value of CEA mHNA level was at 31.21 copies/ml, the Youden's index is the highest. (2) When FCC (+) considered as M1 to make a new TNM staging, the 5-year survival rate showed as below: Ⅰ-Ⅱ, P=0. 134; stage Ⅱ-Ⅲ P=0.004 and Ⅲ-Ⅳ P=0.022,repecetively. Conclusion (1) The best cut-off value of CEA mRNA levels for FCC in peritoneal washes is 31.2 copies/ml. (2) Our study demonstrated that application of FCC(+) in the TNM staging may have a better estimation of prognosis of patients suffering from advanced gastric cancer.

Objective:To investigate the application of Coronary Artery Disease-Reporting and Data System (CAD-RADS) in the diagnosis of coronary atherosclerotic heart disease(CAD) and its risk factors,and to clarify the effective strength of different risk factors in the diagnosis of CAD by using CAD-RADS.Methods:All the data of 266 patients,who were initially suspected with CAD and underwent CT angiography,were collected and diagnosed by using CAD-RADS and were divided into CAD group(n=174) and non-CAD group(n=69).The informations of age,gender,hypertension,hyperlipemia,diabetes,smoking,serum uric acid (UA) levels,and plasma fibrinogen (FIB) levels of the patients in two groups were analyzed;single factor analysis and multivariate Logstic regression analysis were used to analyze the risk factors of CAD diagnosed by CAD-RADS.Results:Compared with non-CAD group,the ratios of male,hypertension,diabetes,smoking of the patients in CAD group were increased (P<0.05),and the age and the level of UA of the patients in CAD group were also increased (P<0.05).The Logistic regression analysis results showed that age and diabetes were the independent risk factors for CAD diagnosed by CAD-RADS.Conclusion:There are many independent risk factors for CAD diagnosed by CAD-RADS,and age and diabetes are the most correlated risk factors for CAD.

BACKGROUND:There is lack of effective diagnostic methods for early knee osteoarthritis. Proteomics refers to the large-scale experimental analysis of proteomes from the overal level of intracel ular protein compositioon, expression and modification, based on which, we can understand protein-protein interaction and relationship, thereby revealing protein functions and cel activity patterns. OBJECTIVE:To apply the isobaric tags for relative and absolute quantitation (iTRAQ) to identify proteins differential y in serums of osteoarthritis Kel gren-Lawrence classification at each stage, and to find out potential molecular markers at each stage of osteoarthritis. METHODS:Sixty patients with knee osteoarthritis were enrol ed, and according to Kel gren-Lawrence (K-L) grading, they were subdivided into K-L 0, II and IV groups. There were 10 males and 10 females randomly selected in each group. Proteins differential y regulated in serums were identified by the stable isotopes 116, 117, 118 of the iTRAQ labeled, reversed-phase column separation, mass spectrometry and Swissport database search, after the serums were subjected to high abundance proteins depletion. Final y, we analyzed the proteins identified by using bioinformatics software. RESULTS AND CONCLUSION:Total y 169 proteins were identified through iTRAQ peptides experiments of different sample tags, Q-star mass spectrum identification and MASCOT library search. 153 proteins were identified as K-L 0 to K-L IV, 153 proteins were identified as K-L 0 to K-L II, and 145 proteins were identified as K-L II to K-L IV. iTRAQ technology may help to identify novel serum markers for early diagnosis of knee osteoarthritis, indicating iTRAQ technology for proteomics serum biomarkers of osteoarthritis study has good application prospect.

Objective To establish a more sensitive method to detect free cancer cells in peritoneal washings of gastric cancer cases during surgery. Methods The CEAmRNA levels in peritoneal washings in 65 cases of gastric cancer were detected by Real-time RT-PCR. PLC was applied simultaneously to detect free cancer cells. Negative controls included the peritoneal washings from 5 cases of benign gastric diseases and the blood samples from 5 cases of healthy adult volunteers. Results (1)CEAmRNA was not found in peritoneal washings in benign gastric diseases and in blood of healthy adult volunteers. (2)The positive percentage of free cancer cells detected by Real-time RT-PCR was 47.7%, while PLC′s was only 12.3%.(3)The positive rate of CEAmRNA showed a significant difference between gastric cancer with serosal invasion and without serosa invasion groups, between peritoneal metastasis group and no peritoneal metastasis groups, and also between stages I+II and III+IV diseases(all P

To evaluate the efficacy and safety of Chinese patent medicines in the treatment of ankylosing spondylitis(AS) by frequency network Meta-analysis. Randomized controlled trials(RCTs)of Chinese patent medicines for AS were retrieved from CNKI, Wanfang, VIP, CBM, PubMed, EMbase and Cochrane Library databases from the time of database establishment to January 2021. The quality of the included RCTs was evaluated according to the Cochrane bias risk standard, and the data was analyzed by RevMan 5.3 and Stata/MP 15.1. A total of 12 kinds of Chinese patent medicines in 55 RCTs were included. According to Meta-analysis, in term of the effectiveness, the top three optimal medication regimens were Biqi Capsules, Yishen Juanbi Pills and Yaobitong Capsules combined with western medicine. The top three interventions to reduce the erythrocyte sedimentation rate(ESR)were Yishen Juanbi Pills, Xianling Gubao Capsules and Fufang Xuanju Capsules combined with western medicine. The top three interventions to reduce the C-reactive protein(CRP)were Biqi Capsules, Xianling Gubao Capsules and Fufang Xuanju Capsules combined with western medicine. In terms of the safety, top three optimal medication regimens were Total Glucosides of Paeony Capsules, Yishen Juanbi Pills, and Wangbi Tablets combined with western medicine. This network Meta-analysis suggests that Chinese patent medicines combined with conventional western medicine can effectively improve the joint pain symptoms of AS patients and reduce the acute inflammatory indicators, with high safety. However, the literature included in this study is generally of low methodological quality, and the conclusion needs to be verified by high-quality research.
