This study was aimed to investigate the curative effect on external application and rectal instillation with Chinese medicine in the treatment of chronic renal failure (CRF) with acute gouty arthritis (GA). A total of 82 CRF patients with acute GA from the First People's Hospital of Hengyang City were randomly divided into the study group (n = 42), which was treated with external application and rectal instillation with Chinese medicine, and the control group (n = 40), which was treated with prednisone. The comparison was made on symptoms and body signs of GA, blood uric acid, creatinine, creatinine clearance, adverse reaction, and recurrence rate between two groups. The re-sults showed that there was no significant difference on alleviating of joint swelling and pain between the study group and the control group. Compared with pretreatment, the blood uric acid and creatinine were significantly decreased after treatment in the study group (P< 0.01). The creatinine clearance was obviously increased (P < 0.05). There were no significant differences on blood uric acid, creatinine and creatinine clearance in the control group before and after treatment. There was no adverse reaction in the study group. In the one-month follow-up, there were only three recurrent cases in the study group, which were obviously better than the control group (P< 0.01). It was concluded that external application and rectal instillation with Chinese medicine had a good curative effect on CRF with acute GA in the near future with low recurrence rate and no adverse reaction, which was worthy of popularizing in the clinical practice.

Objective To evaluate the vaccine effectiveness ( VE) in children who received one dose of live attenuated varicella vaccine. Methods A questionnaire-based 1 ∶ 2 matching case-control study was conducted during May, 2015 to April, 2016 to evaluate the VE based upon the demographic data, vacci-nation status and clinical symptoms of 127 children with varicella and 254 healthy subjects under 12 years old. Results Compared with the healthy subjects, 83. 46% of the patients with varicella were immunized with one dose of varicella vaccine, which was lower than that of the control group (90. 55%) (χ2=4. 08, P<0. 05). The overall protective rate of one dose of varicella vaccine reached 64. 29% (95% CI:42. 00%-78. 00%). Of the 127 cases of varicella, 83. 46% were breakthrough cases immunized with one dose of var-icella vaccine. Primary cases presented more severe clinical symptoms than breakthrough cases. The longer the interval between vaccination and varicella-zoster virus infection was, the more severe the breakthrough cases would be. Conclusion Varicella vaccine is effective for preventing varicella, but the VE of one dose of varicella vaccine is limited. A two-dose varicella vaccination strategy should be proposed in our country as soon as possible.

Objective To investigate the usage of oral cardio-cerebrovascular Chinese patent medicine in Tiantan Community Health Service Center of Beijing (hereinafter referred to as “the centre”) during 2010-2015. Methods Varieties, dosage and sales amount of oral cardio-cerebrovascula Chinese patent medicine during 2010-2015 were analyzed through hospital information system database of the centre. DDDs, DDC and B/A values were calculated. Results Oral cardio-cerebrovascular Chinese patent medicine accounted for 23.67% of all kinds of medicine during 2010-2015. The average annual growth rate of the amount of sales was 11.96%, accounting for 48.73% of total sales. DDDs showed an upward trend over six years, including DDDs of Compound Danshen Dirpping Pills ranking the first. DDC and B/A also showed the daily cost of most of oral cardio-cerebrovascular Chinese patent medicine was less than 10 yuan. B/A value was approximately equal to 1, indicating that these kinds of medicine had better synchronization, and high frequency of usage. Oral cardio-cerebrovascular Chinese patent medicine dominated in all kinds of Chinese patent medicine during 2010-2015, which was related to the reason that most patients were old people. The frequentness during 2010-2015 in the centre did not changed much, and the structure was relatively stable. Conclusion The usage of oral cardio-cerebrovascular Chinese patent medicine in the center is reasonable, with some problems, which need to be further supervised.

Objective To investigate the effects and mechanisms of prostaglandin E2 receptor subtype 3 (EP3) on transforming growth factor β1 (TGF-β1)-induced mouse mesangial cells damage. Methods Primary mouse mesangial cells were separated and cultured. Three siRNAs were synthesized and transfected into mesangial cells for silencing EP3 by LipofectamineTM 2000 and the best one was chosen. MCs were grouped into: (1)control group; (2)TGF-β1 (10 μg/L) group; (3)NC-siRNA plus TGF-β1 (10 μg/L) group; (4) EP3-siRNA group; (5)EP3-siRNA plus TGF-β1 (10 μg/L). Then the proliferation of MCs was evaluated by CCK-8 assay. The expression of PGE2 and cAMP in cell supernatant were detected by ELISA. The mRNA and protein expression of fibronectin (FN), connective tissue growth factor (CTGF), cyclooxygenase-2 (COX2), membrane-bound prostaglandin E2 synthase 1 (mPGES1) were detected by real - time quantitative PCR and Western blotting. The phosphorylation of p38 MAPK and ERK1/2 was decected by Western blotting. Results Compared with control group, the cell proliferation induced by TGF-β1 was increased (P<0.05), the expression of PGE2 and cAMP were improved, mRNA and protein expression of FN, CTGF, COX2 and mPGES1 were up-regulated (all P<0.05). Compared with TGF-β1 group, the cell proliferation in EP3-siRNA plus TGF-β1 group was reduced, the expression of FN, CTGF, COX2 and mPGES1 mRNA and protein were downregulated (all P<0.05), the phosphorylation of ERK1/2, p38 MAPK were also declined (P<0.05). Conclusion EP3-siRNA may reduce TGF-β1-induced cell damage through upregulating the expression of cAMP, repressing the activity of ERK1/2 and p38 MAPK, inhibiting the expression of COX2 mPGES1 and PGE2 by feedback, then decreased the expression of FN and CTGF.

Objective:To compare the difference between the combined diagnostic effect of plasma Septin9(SEPT9) and polyligand Syndecan-2(SDC2) methylation with four serum tumor markers in the diagnosis of colorectal cancer.Methods:In this study, 128 patients who were treated in the affiliated Hospital of Xuzhou Medical University from March to December in 2019 were selected for a case-control study.All the subjects were examined by gastroenteroscopy.According to the pathological results, they were divided into three groups: colorectal cancer group( n=74) and colorectal adenoma group( n=7). The patients with no abnormal or inflammatory polyps or proliferative polyps examined by gastroenteroscopy were taken as the control group( n=47). The methylation levels of SEPT9 gene and SDC2 gene were detected by Roche Lightcycler 480 II real-time fluorescence quantitative polymerase chain reaction, and the concentrations of alpha-fetoprotein, carcinoembryonic antigen, carbohydrate antigen 125 and carbohydrate antigen 199 were detected by Roche Cobas 8000 electrochemiluminescence instrument.Chi-square test was used to compare the positive rate of each marker in the three groups.Medcalc was used to draw the receiver operating characteristic curve (ROC) curve of the subjects′ working characteristic curve, and the value of each index in the diagnosis of colorectal cancer was analyzed. Results:The positive rates of SEPT9 gene and SDC2 gene methylation were 81.1%(60/74) and 67.6%(50/74) respectively in colorectal cancer group, and increased to 85.1%(63/74) after combined detection.The positive detection rates of alpha-fetoprotein, carcinoembryonic antigen, carbohydrate antigen 125 and carbohydrate antigen 199 in colorectal cancer group were 1.4%(1/74), 33.8%(25/74), 6.8%(5/74) and 13.5%(10/74), respectively.When the four tumor markers were detected together, the positive detection rates were only increased to 43.2%(32/74), except for AFP and carbohydrate antigen 125(χ 2=3.847, 2.430, all P>0.05). The differences were statistically significant (χ 2=48.230, 30.487, 43.285, 3.847, 8.788, 6.988, 8.722, all P<0.05). The area under the curve (AUC) of SEPT9 methylation, SDC2 methylation, alpha fetoprotein, carcinoembryonic antigen, carbohydrate antigen 125 and carbohydrate antigen 199 were 0.854 (0.781, 0.910), 0.795 (0.715, 0.861), 0.575 (0.485, 0.662), 0.685 (0.597, 0.764), 0.603 (0.513, 0.689) and 0.631 (0.541, 0.715), respectively.The AUC of combined detection of two DNA methylation markers was better than that of alpha fetoprotein, carcinoembryonic antigen, carbohydrate antigen 125 and carbohydrate antigen 199, and the differences were statistically significant (alpha fetoprotein: Z=4.990, P<0.001; carcinoembryonic antigen: Z=3.743, P<0.001; carbohydrate antigen 125: Z=4.951, P<0.001; carbohydrate antigen 199: Z=3.983, P<0.001). The combined detection of two kinds of gene methylation was better than the combined detection of four kinds of serum markers in the diagnosis of colorectal cancer, and the difference was statistically significant ( Z=3.334, P<0.001). Conclusion:The combined detection of SEPT9 gene and SDC2 gene methylation in plasma is more suitable for non-invasive diagnosis of colorectal cancer than the combined detection of 4 serum tumor markers.

Objective To explore the diagnostic value of four tumor markers analyzed with Logistic regression and receiver operator characteristic (ROC) curve in patients with lung cancer.Methods The serum levels of carcinoembryonic antigen (CEA) 、carbohydrate antigen 125 (CA125),cytokeratin 19 fragment (CYFRA21-1) and neuron specific enolase (NSE) were determined by radioimmunoassay in 112 patients with lung cancer and 74 patients with benign pulmonary disease.Four tumor markers were analyzed by Logistic regression and ROC curve.Results The serum levels of CEA,CA125,CYFRA21-1 and NSE in lung cancer patients were [4.53(2.22-11.53)ng/ml,28.97 (11.39-62.10) U/ml,4.05(2.29-8.18)ng/ml,14.11 (11.35-24.12) ng/ml],respectively,which were significantly higher than those in health adults[2.08 (1.45-2.52) ng/ml,12.90 (9.80-19.44) U/ml,1.53 (1.21-2.17) ng/ml,11.38 (9.07-12.80) ng/ml] (all P ＜ 0.01).According to regression equation Y =1/[1 + EXP (4.902-0.394X1-0.627X2-0.165X3)],the area under the ROC curve (AUC),sensitivity,specificity,and accuracy of new variable Y were 0.915 ± 0.020,79.46％,93.24％,and 84.95％,respectively.Conclusions Application of logistic regression and ROC curve increases diagnostic accuracy in lung cancer.

[Summary] A total of 215 pregnant women at mid-gestation were enrolled, and their serum 25-hydroxyvitamin D levels were measured. Of them, 38 (17. 7%) were classified as cases with vitamin D sufficiency, 70 (32. 5%) as insufficiency, and 107 (49. 8%) as deficiency. Compared with the sufficient group, parathyroid hormone level increased and osteocalcin level decreased significantly in the deficient group. Therefore, vitamin D deficiency is highly prevalent among pregnant women and is associated with their potential disorder of bone turnover.

Objective To explore the distribution characteristics of ankle-brachial index ( ABI) examination for peripheral arterial dis-ease in diabetic patients, and to provide basis for clinical diagnosis. Methods Randomly selected 110 cases of patients who were admitted into our hospital from February 2014 to January 2015, and divided them into the observation group (34 cases with diabetic lower extremity peripheral vascular lesions) and the control group (76 cases without diabetic lower extremity peripheral vascular lesions). Measured the ABI of the two groups, and analyzed the value of ABI data range for the diagnosis of diabetic lower extremity peripheral vascular lesions. Mean-while, analyzed the risk factors of peripheral arterial disease in diabetic patients according to ABI. Results The sensitivity of ABI for diag-nosis of diabetic lower extremity peripheral vascular lesions was 91. 18%, and the coincidence rate was 95. 36%, the specificity was 98. 68%, the misdiagnosis rate was 8. 82%, and the omission diagnostic rate was 8. 82%. ABI of the observation group was obviously lower than that of the control group, and the difference was statistically significant (P<0. 05). Conclusion ABI examination could be basis of clinical diagnosis and important standard of disease assessment for peripheral arterial disease in diabetic patients. It is suggested to strengthen the control of blood glucose, blood pressure and weight of patients with diabetes in order to reduce the risk of morbidity.

OBJECTIVETo evaluate the value of three preoperative imaging methods in the anterolateral thigh flap (ALT) transplantation.

METHODSAccording to preoperative imaging, patients who underwent the ALT flap transplantation were divided into three groups: computed tomography angiography (CTA) group, digital subtract angiography ( DSA) group and magnetic resonance angiography (MRA) group. There were fifteen cases in each group. We compared the imaging quality of the ALT artery among these groups and recorded the parameters of lateral femoral circumflex artery, descending branches and perforators including type, course and size. The results from images were compared with intraoperative findings. The success rate and complications were also recorded.

RESULTSThe preoperative imaging accuracy of the types of the lateral femoral circumflex artery and descending branch was more than 92.3%, with no significant different between any two of three groups (P > 0.05). The difference in diameters of descending branches and perforators from preoperative measurement and from intraoperative measurement was also not significant between any two of the three groups; the success rate and complications were not also obviously different (P > 0.05 , P > 0.05, respectively).

CONCLUSIONSPreoperative mapping using CTA, DSA and MRA is a feasible and reliable method for the flap design in ALT transplantation. As a preoperative evaluation means, CTA and MRA may replace DSA in the ALT transplantation.
