Objective To explore the clinical manifestation, imaging examination, treatment and prognosis of Alagille syndrome in a child combined with hepatocellular carcinoma. Method The clinical manifestation, assistant examination and diagnosis of Alagille syndrome combined with hepatocellular carcinoma were analyzed in the child, and the pertinent literature were reviewed. Results The 6-year-old girl was admitted to hospital for repeated jaundice, and had a history of cardiac surgery. After admission, the patient was found to have a typical face look such as frontal bossing, sunken eyes, pointed chin and hypertrophy of nasal tip. Blood biochemistry showed intrahepatic cholestasis and increased alpha-fetoprotein. Abdominal ultrasonography revealed diffuse multiple solid lesions in the liver. And magnetic resonance imaging of the liver indicated that the liver was enlarged and multiple solid space occupying masses. Jagged 1 gene detection showed heterozygosis mutation of c.1205delC. Conclusion Alagllie syndrome complicated with hepatocellular carcinoma in childhood is extremely rare, and early diagnosis and long-term follow-up are of positive significance for its treatment and prognosis.

Hair follicle (HF), one of the skin appendages, has received a lot of attention to be a new target and pathway for drug delivery. The development of hair follicle targeted drug delivery system (HFTDDS) through percutaneous permeation is particularly important for skin diseases derived from HF such as acne, hair loss, and folliculitis for their on-site action. This review describes the structure and physiological function of HF, the microenvironment of HF, and factors affecting HF permeation. Multiple nanoformulations used to improve the HF permeation and technologies to characterize the HF permeation were introduced. The latest advance of HFTDDS based on nanoformulations were systematically summarized and analyzed in the treatment of acne and hair loss. Finally, the challenges of formulating HFTDDS were discussed. The review is expected to provide some ideas and references for developing delivery systems for treating skin diseases derived from HF.

Abstract: Objective This study aims to explore the prevalence and risk factors of metabolic syndrome (MS) among the adults in Hainan Province, and to provide scientific basis for MS prevention and control. Methods A multi-stage cluster random sampling method was applied to select 3 690 permanent residents aged 18 years and above in Hainan Province. The survey was conducted by trained investigators using household appointments and centralized surveys. A questionnaire survey, physical measurement, and laboratory examination were conducted after the collection of blood samples. The processed samples were then tested by a quality-controlled laboratory. Finally, we analysed the prevalence of metabolic syndrome (MS) and its relationship with population characteristics and health-related behaviors. Results The crude prevalence of MS in the population aged 18 and above in Hainan province was 19.46% and the standardized prevalence was 13.21%, with a higher rate in urban areas (22.21%) than in rural areas (18.13%). The prevalence of MS increased with age (P<0.001), and there were significant differences in MS prevalence among different marital and occupational statuses (P<0.01). Logistic regression results indicated that the age groups of 40-<50 years (OR=2.986, 95%CI:1.355-6.580), 50-<60 years (OR=3.739, 95%CI: 1.715-8.151), 60-<70 years (OR=3.890, 95%CI: 1.769-8.556), 70 years and above (OR=3.927, 95%CI: 1.758-8.771), technical, transportation and production personnel (OR=1.579, 95%CI: 1.033-2.412), retired (OR=1.788, 95%CI: 1.415-2.259), unemployed (OR=1.503, 95%CI: 1.044-2.165), smoking cessation (OR=1.582, 95%CI: 1.162-2.154), insufficient intake of fruits and vegetables (OR=1.196, 95%CI: 1.005-1.422), and insufficient physical activity (OR=1.437, 95%CI: 1.155-1.787) were all associated with the prevalence of MS. Among the investigated subjects, 30.22% of them had one abnormal component, with hyperglycemia being the highest (54.44%); 24.25% of them had two abnormal components, with "hyperglycemia + hypertension" being the highest (33.30%); and 19.46% had three or more components, with "overweight/obesity + hyperglycemia + hypertension" being the highest (24.79%). Conclusions The prevalence of MS in Hainan Province is on the rise, and effective lifestyle intervention measures are needed to reduce the risk of MS.

In order to mutate a carbofuran degrading strain CFDS-1,transposon of pSC123 was introduced into the genomic DNA of strain CFDS-1 by conjugation with E.coli DH5? (pSC123) as donor and strain CFDS-1 as recipient,6 mutants which lost carbofuran degrading ability were obtained with a kanamycin resistant gene in the middle of transposon and the disappearance of a red compound during the degrading of carbofuran as preliminary selecting marks,they were designated as CFDS-M1~CFDS-M6. UV scanning and GS assay results also proved their mutations. PCR was carried out respectively with primers designed according to the sequence of transposon and genomic DNA of 6 mutants as templates,restriction analysis of PCR products showed that the mutation of carbofuran degrading genes of these mutants was caused by transposon insertion.

Abstract: Objective This paper aims to explore the effect of live attenuated varicella vaccine on the sensitivity of tuberculin skin test(TST), and to provide reference for tuberculin skin test in the future. Methods TST and emergency varicella vaccine were administered to students in grade one of a high school in Wuxi, Jiangsu province, who had both TB and varicella cases. Independent-samples t test was used to analyze the mean diameter of induration of TST in day 0, day 83 and day 195. The retrospective cohort study was used to analyze the effect of live attenuated varicella vaccine on TST. Results The mean induration diameter of 45 students who participated in three TST tests on day 0, day 83 and day 195 were analyzed by independent sample t test. On day 0, there was a difference in the mean diameter of TST induration between the unvaccinated and vaccinated groups(1.630±2.837 vs 5.818±4.530) (t=-3.692, P=0.001). On day 83, there was no difference in the mean diameter of TST induration between the two groups(0.001±0.001 vs 0.114±0.533) (t=-1.000, P=0.329). On day 195, there was a difference in the mean diameter of TST induration between the two groups(1.913±3.774 vs 5.023±5.126) (t=-2.309, P=0.026). Moreover, the retrospective cohort study showed that the mean diameter of TST induration changed more significantly after inoculation with varicella vaccine, RR=6.071, 95%CI (1.667-22.116), P<0.05; After inoculation with varicella vaccine, the mean diameter of TST test did not change significantly from day 0 to day 195 with no statistical significance RR=3.474, 95%CI (0.333-36.240), P>0.05. Conclusions Live attenuated varicella vaccine may temporarily affect the sensitivity of tuberculin skin test.
