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 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.

Nitric oxide (NO) is a short-life free radical that acts as the small biological molecule, and exists in body extensively. Since its discovery over 20 years ago, NO has been found to play an important regulation role in angiogenesis, nerve and immune system. The subsequent studies also showed that NO exerted an important biological action in wound repairing and healing, which involved in the following phases of wound repair, inflammation, cell proliferation, matrix deposition and remodeling. This paper reviews recent findings from in vitro & in vivo studies of NO in wound repair, and the biological function and mechanisms of NO in wound repair.

Objective:
To analyze the characteristics and influencing factors of the newly diagnosed cases locally infected with HIV through sexual contact in Jinhua,so as to provide reference for AIDS prevention and control.
Methods:
An epidemiological survey was conducted among the HIV/AIDS cases diagnosed in 2017 in Jinhua to collect the information about demographic characteristics,local infection and sexual behaviors. The logistic regression model was used to analyze the related factors for local HIV infection.
Results:
A total of 438 HIV/AIDS cases infected through sexual contact were recruited,with 272(62.10%)cases infected in Jinhua. The proportion of local infection was 86.67%,79.47%,63.04%,69.09%,77.46% and 77.97%,respectively,among those people aged 60 years or over,permanent residents in Jinhua,employees / students,farmers,those who had lived in Jinhua for more than five years,and those who had a HIV testing in one year. The Results of the multivariate logistic regression analysis showed that heterosexual transmission cases who were permanent residents in Jinhua(OR=3.437,95%CI:1.250-9.451),who had lived in Jinhua for more than five years(OR=3.609,95%CI:1.403-9.284),who had commercial heterosexual behaviors in Jinhua(OR=5.463,95%CI:2.529-11.803)were more likely to be infected with HIV in Jinhua;homosexual transmission cases who were permanent residents in Jinhua(OR=4.812,95%CI:1.744-13.275)and who had non-commercial,temporary homosexual behaviors in Jinhua(OR=10.641,95%CI:4.369-25.916)were more likely to be infected with HIV in Jinhua.
Conclusion
Among the HIV/AIDS cases diagnosed in 2017 infected through sexual contact in Jinhua,having permanent residence,long-term residence,commercial heterosexual behaviors and non-commercial,temporary homosexual behaviors were risk factors for local infection.
