Objective To investigate the therapeutic efficacies for pure galactoma by injecting absolute ethanol compared with the pure pouch cavity puncture separately pulls out the fluid law.Methods Patients of pure galactoma examined by ultrasonography were divided into two groups from March of 2005 to February of 2007 in mammary gland special clinic of our hospital.Absolute ethanol jet method and the pure pouch cavity puncture separately pulls out the fluid law were given respectively and the effect was evaluated within one year after operation.Results Of 89 cases pure galactoma using absolute ethanol jet method,71cases(79.78%)were convalesced,15cases(16.85%)were effective and 3 cases(3.37%)were noneffective.The effectiveness was 96.63 %.Of 86 cases using pure pouch cavity puncture separately pulls out the fluid law,44cases(51.16%)were convalesced,33 cases(38.37%)were effective and 9 cases(10.47%)were noneffective.The effectiveness was 89.53%.The cured rates of two groups had significant difference through chi-square test,?2=15.38,P

Objective To observe the efficacy of proparacaine hydrochloride in preoperative venipuncture. Methods Two hundred and furty patients hospitalized for preoperative venipuncture, between June 2015 to December 2015 in Jiangmen Central Hospital, were equally randomized into the intervention group and control group: the former was treated with proparacaine hydrochloride and the control group used traditional method. Visual analogue scale (VAS) was adopted to assess the effects of the anesthesia effect. At the same time the one-time success rate of puncturing and the adverse reactions were observed and compared between the two groups. Results Patients of the intervention group felt significantly less painful than that the control one (P<0.05). The successful rate of the intervention group was significantly higher than that of the control group (P<0.05). Conclusion Proparacaine hydrochloride is safe and effective for preoperative which reduces pain.

Escherichia coli (E. coli) FadR regulator plays dual roles in fatty acid metabolism, which not only represses the fatty acid degradation (fad) system, but also activates the unsaturated fatty acid synthesis pathway. Earlier structural and biochemical studies of FadR protein have provided insights into interplay between FadR protein with its DNA target and/or ligand, while the missing knowledge gap (esp. residues with indirect roles in DNA binding) remains unclear. Here we report this case through deep mapping of old E. coli fadR mutants accumulated. Molecular dissection of E. coli K113 strain, a fadR mutant that can grow on decanoic acid (C10) as sole carbon sources unexpectedly revealed a single point mutation of T178G in fadR locus (W60G in FadRk113). We also observed that a single genetically-recessive mutation of W60G in FadR regulatory protein can lead to loss of its DNA-binding activity, and thereby impair all the regulatory roles in fatty acid metabolisms. Structural analyses of FadR protein indicated that the hydrophobic interaction amongst the three amino acids (W60, F74 and W75) is critical for its DNA-binding ability by maintaining the configuration of its neighboring two β-sheets. Further site-directed mutagenesis analyses demonstrated that the FadR mutants (F74G and/or W75G) do not exhibit the detected DNA-binding activity, validating above structural reasoning.

OBJECTIVE: To carry out prenatal diagnosis and genetic analysis for a fetus with disorders of sex development (DSDs). METHODS: A fetus with DSDs who was identified at the Shenzhen People's Hospital in September 2021 was selected as the study subject. Combined molecular genetic techniques including quantitative fluorescence PCR (QF-PCR), multiplex ligation-dependent probe amplification (MLPA), chromosomal microarray analysis (CMA), quantitative real-time PCR (qPCR), as well as cytogenetic techniques such as karyotyping analysis and fluorescence in situ hybridization (FISH) were applied. Ultrasonography was used to observe the phenotype of sex development. RESULTS: Molecular genetic testing suggested that the fetus had mosaicism of Yq11.222qter deletion and X monosomy. Combined with the result of cytogenetic testing, its karyotype was determined as mos 45,X[34]/46,X,del(Y)(q11.222)[61]/47,X,del(Y)(q11.222),del(Y)(q11.222)[5]. Ultrasound examination suggested hypospadia, which was confirmed after elective abortion. Combined the results of genetic testing and phenotypic analysis, the fetus was ultimately diagnosed with DSDs. CONCLUSION This study has applied a variety of genetic techniques and ultrasonography to diagnose a fetus with DSDs with a complex karyotype.
