Objective To evaluate the correlating clinical factors of coronary artery calcification score(CACS).Methods 141 patients suspected of coronary artery disease were included.They underwent multi-slice row computed tomography,pulse wave velocity ( PWV ),UCG and blood biochemistry within a period of 3 months.The subjects were divided into three groups according to CAC score:A(CACS =0-10),B ( CACS = 11-400),C ( CACS > 400).Results CACS was significantly associated with age,history of hypertension and diabetes mellitus.It was also associated with the presence of mitral annular calcification and aortic valve calcification,low ankel brachial pressure index(ABI) and high mean artery pressure(MAP) as well as high values of brachial ankel PWV (baPWV) and Upstroke time (UT).Muhifactorial logistic regression analysis showed that the presence of aortic valve calcification and mitral annular calcification,the history of diabetes mellitus and high value of UT were independently correlated with severe coronary artery calcification.Conclusions Aortic valve calcification,mitral annular calcification,history of diabetes mellitus,high value of UT were independently correlated with severe coronary artery calcification.Measurement of PWV and UCG should be performed before muhi-slicerow computed tomography,because the assessment of coronary artery lumen narrowing with multi-slice row computed tomography can not be carried out accurately in the presence of severe coronary artery calcification.

BACKGROUNDTotal hip arthroplasty (THA) in developmental dysplasia of the hip (DDH) is more complex than the normal hip, with large replacement risks and many complications. Although nonosteotomy THA is convenient to perform, femoral osteotomy shortening can avoid blood vessel and nerve traction injuries. This study aimed to compare osteotomy THA with nonosteotomy to determine reasonable options for operative management of DDH.
METHODSData on 48 DDH patients who underwent THA were analyzed retrospectively. The patients were divided into two groups: Group A 29 cases (nonosteotomy), and group B 19 cases (osteotomy). Harris and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores, limb length discrepancy (LLD), radiological data on the hip, and claudication were evaluated. Data were analyzed by using paired-sample Student's t-test, independent-sample Student's t-test, and Pearson's Chi-square test; the test level was α =0.05.
RESULTSPostoperative Harris (90.7 ± 5.1) and WOMAC scores (88.0 ± 10.6) were significantly improved compared with preoperative Harris (44.8 ± 5.7) and WOMAC scores (42.0 ± 5.3) in group A (P < 0.05). Postoperative Harris (90.4 ± 2.8) and WOMAC scores (88.2 ± 5.9) were significantly improved compared with preoperative Harris (44.4 ± 4.2) and WOMAC scores (43.2 ± 4.3) in group B (P < 0.05). One case of dislocation occurred in group A; after closed reduction, dislocation did not recur. In group A, 2 patients developed cutaneous branch injury of the femoral nerve, which spontaneously recovered without treatment. Postoperative LLD >2 cm was seen in one case in group A and five cases in group B. Postoperative claudication showed no significant difference between the two groups (P > 0.05). No patients developed infection; postoperative X-rays showed that the location of the prosthesis was satisfactory, and the surrounding bone was not dissolved.
CONCLUSIONSTHA is effective and safe for DDH. For unilateral high dislocation DDH patients with limb lengthening ≤4 cm and good tissue conditions, THA without femoral osteotomy may be considered.

Objective To compare the response measures and outcomes of SARS-CoV(2003), H1N1 influenza(2009), H7N9 influenza(2013)and COVID-19(2020)in Shanghai and provide scientific evidence for the emergency response of public health emergencies. Methods We compared the response measures and outcomes of the four epidemics in Shanghai in the aspects of government response, prevention and control system, scientific and technological support, social mobilization and prevention effects, using critical incident analysis based on the time axis of the epidemics from literature review. Results In response to the four epidemics of infectious diseases occurred in 2003-2020, Shanghai has generally made some significant effort and flexible measures in the first month of the epidemics, including"closure of live poultry markets"and"three closed-loops and four 100% coverage"and other specific prevention and control measures, which have enhanced the prevention and control system. However, we identified that the construction of prevention and control system for public health emergencies remained inefficient, compared to rapid economic development. The majority of the construction measures were principally post-epidemic. In addition, there were many challenges, such as passive response, temporary response teams and measures, and difficulties in the flexible bottom-up response for residents, families and industries without standard operating procedure and guidelines. Conclusion It may be an effective measure for the prevention and control of infectious diseases to build joint prevention and control measures with mass participation and regular drills, in the perspectives of strategic, tactical and operational levels of epidemic prevention and control.

BACKGROUNDAfter establishing a murine model of aminoglycoside antibiotic (AmAn) induced ototoxicity, the sensitivity of AmAn induced ototoxicity in three murine strains and the effect of kanamycin on the expression of Na-K-2Cl cotransporter-1 (NKCC1) in stria vascularis were investigated.
METHODSC57BL/6J, CBA/CaJ, NKCC1(+/-) mice (24 of each strain) were randomly divided into four experimental groups: A: kanamycin alone; B: kanamycin plus 2, 3-dihydroxybenzoate; C: 2, 3-dihydroxybenzoate alone; and D: control group. Mice were injected with kanamycin or/and 2, 3-dihydroxybenzoate twice daily for 14 days. Auditory brainstem response (ABR) was measured and morphology of cochlea delineated with succinate dehydrogenase staining. Expression of NKCC1 in stria vascularis was detected immunohistochemically.
RESULTSAll three strains in groups A and B developed significant ABR threshold shifts (P < 0.01), which were accompanied by outer hair cell loss. NKCC1 expression in stria vascularis was the weakest in group A (A cf D, P < 0.01) and the strongest in groups C and D (P < 0.05). CBA/CaJ mice had the highest sensitivity to AmAn.
CONCLUSIONSAdministration of kanamycin established AmAn induced ototoxicity. Kanamycin inhibited the expression of NKCC1 in stria vascularis. 2, 3-dihydroxybenzoate attenuated AmAn induced ototoxicity-possibly by enhancing the expression of NKCC1. Age related hearing loss did not show additional sensitivity to AmAn induced ototoxicity in murine model.

BACKGROUNDThe Akt2 protein kinase is thought to be a key mediator of the insulin signal transduction process. Akt2 is suggested to play a role in glucose metabolism and the development or maintenance of proper adipose tissue and islet mass. In order to determine whether the Akt2 gene plays a role in the pathogenesis of type 2 diabetes characterized by insulin resistance, and to further identify if variations in this gene have a relationship with type 2 diabetes, we sequenced the entire coding region and splice junctions of Akt2 and made a further case-control study to explore the association between single-nucleotide polymorphisms (SNPs) in this gene and type 2 diabetes in the Chinese Han population.
METHODSWe selected 23 probands with a type 2 diabetic pedigree whose family members' average onset age was within 25 to 45 years old. The body mass index of all the participants was lower than 28 kg/m(2) and all of them were insulin-resistant (the fasting insulin level > 100 pmol/L or 16 µIU/ml). The entire coding region and splice junctions of Akt2 were directly sequenced in these 23 probands. SNPs with a frequency of minor allele over 20 percent were selected to be further studied in a case-control study. We chose 743 non-diabetic subjects as the control group and 742 type 2 diabetic patients as the case group. All these subjects were genotyped. A Snapshot Technology Platform (Applied Biosystems) was used for genotyping.
RESULTSThe Akt2 genes from all 23 subjects were successfully sequenced. We did not identify any mutation in the type 2 diabetic pedigree. Two SNPs were identified, 13010323T > C and 13007939G > T. 13010323T > C was in intron 9, which was the location of rs2304188 reported in Genbank. Its minor allele frequency was 13.04%. 13007939G > T was in the 3'-untranslated region (UTR) of exon 14, which was the location of rs2304186 reported in Genbank. Its minor allele frequency was 34.78%. The allele frequency of rs2304188 and rs2304186 were consistent with the frequency reported in Genbank. In the case-control study with 742 patients and 743 controls, there was no significant difference between the two groups for the allele frequency of rs2304186 (odd ratio: 0.96, 95% confidence interval: 0.82 - 1.12, P = 0.597).
CONCLUSIONSThe Akt2 gene is not a major cause of diabetes in a non-obese Chinese Han population characterized by insulin resistance. There is no significant relationship between rs2304186 and type 2 diabetes in the Chinese Han population.
