ABSTRACT
Objective To investigate the expression of platelet-derived growth factor B(PDGF-B) and PDGFR-α mRNA in the skin lesion of recurrent condyloma acuminatum(CA) and to explore its relationship with recurrent condyloma acuminatum.Methods The expressions of PDGF-B and PDGFR-α mRNA in the lesions of recurrent CA and Nonrecurrent CA were investigated by Real-Time-PCR,and the normal foreskins weretaken as controls.Results The PDGF-B and PDGFR-α mRNA levels in the re current CA group and non-recurrent CA group were significantly higher than those in the normal control group,the differences were statistically significant(P＜0.05).The expressions of PDGF-B and PDGFR-α mRNA in the recurrent CA group were higher than those in the non-recurrent CA group(P＜0.01).Furthermore,the expressions of PDGF-B and PDGFR-α mRNA before treatment in the recurrent CA group were higher than those after treatment(P＜0.01).Conclusion PDGF-B and PDGFR-α mRNA might haue a certain relation with CA recurrence.
ABSTRACT
Objective To investigate the predisposing factors and clinical features of disseminated herpes zoster, and to explore factors influencing postherpetic neuralgia. Methods Clinical data were collected from 53 patients with disseminated herpes zoster and 809 patients with common herpes zoster between 2012 and 2015, and analyzed retrospectively. Logistic regression analysis was used to assess factors influencing the occurrence of and pain intensity in disseminated herpes zoster, as well as the occurrence of postherpetic neuralgia. Results No significant difference in patients′age was observed between the disseminated and common herpes zoster groups(56.66 ± 17.24 vs. 56.50 ± 15.51 years, t=0.071, P>0.05), but there was a significant difference in the gender ratio between the two groups(χ2 = 8.16, P = 0.004). The incidence rates of bullae, pustules and fever were all significantly higher in the disseminated herpes zoster group than in the common herpes zoster group(15.09%vs. 3.58%,χ2=16.04, P<0.01;47.17%vs. 26.82%,χ2=10.20, P<0.01;30.19%vs. 8.03%,χ2=28.68, P<0.01). The disseminated herpes zoster group also showed significantly higher pain scores at admission compared with the common herpes zoster group (Median[P25- P75]: 6[4- 7.5] vs. 5[3- 7], Z =-3.460, P = 0.001). Logistic regression analysis revealed that gender, age, fatigue and HIV infection were significantly associated with the occurrence of disseminated herpes zoster (all P<0.05). Additionally, HIV infection(OR=5.570, 95%CI:1.196-25.939, P=0.029), gender(OR=0.166, 95%CI:0.029-0.945, P=0.043), age(OR=1.064, 95%CI:1.010-1.119, P=0.019)and the number of days that antiviral therapy lasted(OR=0.669, 95%CI:0.505-0.885, P=0.005)were all factors influencing the occurrence of postherpetic neuralgia. Conclusion Male, old age, fatigue and especially HIV infection are risk factors for the occurrence of disseminated herpes zoster, and male, old age and antiviral therapy duration may be associated with the occurrence of postherpetic neuralgia.
ABSTRACT
<p><b>OBJECTIVE</b>To detect mutation of ADAR1 gene in a family affected with dyschromatosis symmetrica hereditaria.</p><p><b>METHODS</b>Clinical data and blood samples of the family were collected. Potential mutation of the ADAR1 gene were scanned in 3 patients and 3 unaffected members by PCR amplification and direct sequencing. The coding sequences of the ADAR1 were also screened in 50 normal controls.</p><p><b>RESULTS</b>A frameshift mutation (c.2252insG) of the ADAR1 gene was identified in all of the 3 patients. The same mutation was not found in the 3 unaffected members and 50 normal cases.</p><p><b>CONCLUSION</b>The frameshift mutation of ADAR1 gene (c.2252insG) is probably responsible for the disease in this family.</p>

Objective To evaluate the incidence of and risk factors for syphilis seroconversion amomg drug addicts during methadone maintenance treatment (MMT).Methods A retrospective study was performed on drug addicts receiving MMT at MMT clinics in Maanshan,who were seronegative for syphilis before the treatment and followed up by serological tests for syphilis for more than two years.The incidence of and risk factors for syphilis seroconversion during the two years of follow up were analyzed in all the subjects.Results A total of 161 drug addicts were included in this study,of whom,15 experienced seroconversion for syphilis with the average seroconversion rate being 4.66 per 100 person-years.The seroconversion tended to occurr in the early stage of MMT.Both Chi-square analysis and multivariate logistic regression analysis showed that syphilis seroconversion was independently associated with nonuse of condoms during the last sexual behavior before receiving MMT.Conclusions Interventions should be undertaken as early as possible to promote safe sexual behaviors among drug addicts at methadone clinics,and to promote condom use is especially important for blocking sexual transmission of diseases.
ABSTRACT
AIM: To determine the mycoplasma infection and the drug resistance in outpatients with NGU. METHODS: Mycoplasma culture, identification and drug sensitivity assay were carried out with samples of 472 NGU patients by using one complex mycoplasma kit. RESULTS: 153 in 472 cases showed mycoplasma positive. The total positive rate was 32.4%. The positive cases of Uu, Mh and mixed both infection were 112( 23.7%), 11( 2.3%), and 30( 6.4%), respectively. The female positive rate was found significantly higher than that of male (? 2= 4.157,P
