Objective To sum up the experience on diagnosis and treatment of Hashimoto disease and its concurrent thyropathy. Methods Clinical data were analyzed on 52 cases of Hashimoto disease(HD) surgically found to have concurrent thyropathy from Jan 1984 to Jun 2001 out of 138 HD cases undergoing surgery. Results Thyroid nodules were found in all 52 HD cases, among which 17 were with thyroid cancer, 2 with malignant lymphoma, 5 with thyroid adenoma, 2 with hyperthyroidism, and 26 with nodular goiter. Thyroidectomy of different extent was performed. Postoperatively all cases were given thyroxine. On follow-up a patient with malignant lymphoma died, and one patient suffered hypothyroidism. Conclusion HD is a ubiquitous disease. The clinical diagnosis of is still difficult. HD cases complicated with thyroid nodules should be treated surgically to exclude malignant tumors. Intraoperative frozen section is a reliable diagnostic method and may guide the surgical modality.

Objective To asses the effects of Gamma nail and DHS/Richard (dynamic hip screw) in the treatment of proximal femoral fractures. Methods A meta analysis of all the relevant randomized controlled trials (RCTs) was performed. We included randomized and quasi randomized controlled trials in patients with proximal femoral fracture to compare Gamma nail and DHS/Richard. Results First we identified 88 papers on comparison of Gamma nail and DHS/Richard in the treatment of proximal femoral fractures published from 1969 to 2003. 7 trials involving 1256 patients were identified as meeting all the eligibility criteria. 3 investigators independently graded study quality and abstracted relevant data, including information on mortality rates, wound infection, function, revision in patients with a proximal femoral fracture. 4 trials, which included a total of 621 patients, provided detailed information on mortality rates over the first 6 postoperative months. We found there was no significant difference in the relative risk of death in the first 6 months postoperative between treatments of Gamma nail and those of compression hip screw (relative risk 1.17;P=0.51). 6 trials that included a total of 1083 patients provided data on operative complications. The risk of operative complications from Gamma nail fixation appeared to be higher than that from compression screw and side plate fixation but not higher than that from compression hip screw (relative risk 1.41; P=0.02). We also found an obvious increase in the relative risk of fracture of femoral shaft between Gamma nail and compression hip screw (relative risk 6.99; P=0.00). Patients treated with Gamma nail had a higher rate of revision compared with those with compression hip screw, but there was no significant difference between the two groups (relative risk 1.85; P=0.20). In addition, wound infection, operative blood loss and functional recovery were similar between the tow groups(relative risk 0.98 for wound infection and 1.02 for function). Operating time for Gamma nail patients was significantly less than that for DHS/Richard ones (P

AIM: Anti-atherosclerosis effects of Momordica charantia L was further studied in a New Zealand rabbit atherosclerotic model at the basis of anti-inflammation and antioxidant effects. METHODS: Animals were divided into 3 groups: normal group (normal rabbit diet), atherosclerosis group(diet containing 2% cholesterol), and Momordica charantia L group(diet containing 2% cholesterol and 1 5% sarcocarp of Momordica charantia L ). Ninety days later, all animals were sacrificed. The effect of Momordica charantia L on atherosclerosis was evaluated by measuring serum lipid and total cholesterol content of artery wall, observing fatty liver degree, aorta arteriosclerotic area, and the thickness of intima. RESULTS: The level of total serum cholesterol and LDL-C in Momordica charantia L treatment group were obviously lower than those in atherosclerosis group, so were the total cholesterol content of artery wall, fatty liver degree, atherosclerotic area, intima thickness and I/M ratio, but no significantly difference was found between the two groups in TG level. The level of HDL-C in Momordica charantia L treatment group was evidently lower than that in normal control group. CONCLUSION: Momordica charantia L has an anti-atherosclerosis action in rabbits.

Objective:To investigate the expression of aromatase of renal tissue in systemic lupus erythematosus(SLE)model mice.Methods:BALB/c mice were induced SLE with homologuous splenic cell activated with ConA after being ovariectomized,and in the same time administered different doses of benzestrofol.E2 in peripheral blood and renal tissue was detected by ELISA and the expression of mRNA of aromatase in renal tissue was detected by RT-PCR in the 4th,6th,8th and 10th weeks.Results:The level of E2 of peripheral blood and renal tissue of SLE model mice became higher as benzestrofol exogenously administered heightened.Compared with control mice,the level of E2 in SLE model mice increased,and the expression of mRNA of aromatase of renal tissue increased with E2 increment.Conclusion:E2 promotes development of SLE through regulating expression of aromatase mRNA.

Objective: To understand the molecular characteristics of hemagglutinin (HA) and neuraminidase (NA) as well as the disease risk of influenza virus A H7N9 in Guizhou province. Methods: RNAs were extracted and sequenced from HA and NA genes of H7N9 virus strains obtained from 18 cases of human infection with H7N9 virus and 6 environmental swabs in Guizhou province during 2014-2017. Then the variation and the genetic evolution of the virus were analyzed by using a series of bioinformatics software package. Results: Homology analysis of HA and NA genes revealed that 2 strains detected during 2014-2015 shared 98.8%-99.2% and 99.2% similarities with vaccine strains A/Shanghai/2/2013 and A/Anhui/1/2013 recommended by WHO, respectively. Two strains detected in 2016 and 14 strains detected in 2017 shared 98.2%-99.3% and 97.6%-98.8% similarities with vaccine strain A/Hunan/02650/2016, respectively. Other 6 stains detected in 2017 shared 99.1%-99.4% and 98.9%-99.3% similarities with strain A/Guangdong/17SF003/2016, respectively. Phylogenetic analysis showed that all the strains were directly evolved in the Yangtze River Delta evolution branch, but they were derived from different small branch. PEVPKRKRTAR↓GLF was found in 6 of 24 strains cleavage site sequences of HA protein, indicating the characteristic of highly pathogenic avian influenza virus. Mutations A134V, G186V and Q226L at the receptor binding sites were found in the HA. All the strains had a stalk deletion of 5 amino acid residue "QISNT" in NA protein, and drug resistance mutation R294K occurred in strain A/Guizhou-Danzhai/18980/2017. In addition, potential glycosylation motifs mutations NCS42NCT were found in the NA of 9 of 24 strains. Conclusions: HA and NA genes of avian influenza A (H7N9) virus showed genetic divergence in Guizhou province during 2014-2017. The mutations of key sites might enhance the virulence of the virus, human beings are more susceptible to it. Hence, the risk of infection is increasing.

Objective To compare the effect of three methods in diagnosis of plague by detecting of Yersina pestis F1 antigen. Methods In natural foci of plague, wild animal samples, such as blood, liver, spleen,and lymphoid tissue were collected, and the three methods of enzyme linked immunosorbent assay (ELISA),reverse indirect hemagglutination assay(RIHA) and gold-immunochromatography assay(GICA) were employed to detect F1 antigen of Yersina pestis. Results Total of 414 infused organ samples of natural death and captured wild animals in natural foci of plague were determined. Positive samples detected by GICA and ELISA were the same,the positive rates were 5.31%(22/414), both positive and negative coincidence rates were consistently 100%. Only 18 samples were positive by retrial in 186 samples with more than 2 holes aggregation by preliminary examination of RIHA, with nonspecific agglutination rate of 40.6% (168/414) and positive rate of 4.35% (18/414). The positive coincidence rate was 81.82% (18/22) between RIHA with GICA and ELISA, and negative coincidence rate was statistically significant(t = 4.379, P ＜ 0.01). Conclusions ELISA, RIHA and GICA can be used for early diagnosis of plague by detecting F1 antigen. The results of RIHA have quantitative significance, with higher non-specific agglutination rate, and heavy workload of re-examination; GICA and ELISA has the same specificity and sensitivity, but the results of GICA is only qualitative. ELISA excluded the defect of RIHA and GICA, and combines the advantages of both methods.

Objective To analyse the feasibility of detecting F1 antibody to Yersinia pestis in flushing fluid of heart blood of Rhombomys opimus with enzyme linked immunosorbent assay(ELISA) method and its application value in surveillance of the disease. Methods Serum, flushing fluid of heart blood and infusion fluid of liver and spleen of Rhombomys opimus, which were caught by capture in the plague focus of Zunger basin in 2007, were taken to carry out detection for F1 antibodies to Yersinia pestis with ELISA method. The data were processed with SPSS 17.0. Results Positive rate and average titer of serum were 12.35%(11/162) and 25.35, of flushing fluid of heart blood were 10.49%(17/162) and 23.75 and of the infusion fluid of liver and spleen 6.79%(17/162) and 2240,respectively. No statistical difference was found in positive detection rate when it was compared between serum and flushing fluid of heart blood(χ2 = 1.333, P ＞ 0.05), but it was obviously different between serum and infusion fluid of liver and spleen(χ2 = 7.111, P ＜ 0.01 ) and between flushing fluid of heart blood and infusion fluid of liver and spleen(x2 = 6.250, P ＜ 0.05). There was a significant difference in average titer between serum, flushing fluid of heart blood and infusion fluid of liver and spleen(t = 2.290, 3.612, P ＜ 0.05 or ＜ 0.01 ). The plague F1 antibody positive coincidence rate of serum and flushing fluid of heart blood was 85.0%(17/20), of serum and infusion fluid of liver and spleen was 55.0% (11/20), and of flushing fluid of heart blood and infusion fluid of liver and spleen was 64.7%(11/17). Conclusions The ELISA method can detect Fl antibody in flushing fluid of heart blood,and the method is feasible in plague surveillance.
