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.

Objective To analyze five kinds of allogenic acellular peripheral nerve by different meth-ods and try to establish a standard method for preparing nerve materials. Methods Five kinds of nerve ma-terial prepared by different chemical extractions according to nowaday articles were examined by HE staining. Irmnunohistochemistry and protein ratio was studied by allogenic nerves by virtue of Kjeldahl method in order to know the efficiency of these methods in removal of SCs axons and integrality of the basilar membrane. Results Myelin sheath and cytoblast in group 2 that nerves were extracted by Triton X-100 and Sodium de-oxycholate consecutively twice were completely removed, which was well demonstrated in HE staining. Per-ineurium in red staining were arranged wave-like longitudinally, axons and myelin sheath were replaced by column-like spacing. Col I staining were positive in all groups, structure of basilar membrane became loose slightly in the first and second group, and the structure of the other groups were relatively regular. Group 1 and 2 were negative in S-100 staining. There was no difference between group 2 and group 1,3,4 and 5 in sheath removal demonstrated by TEM. Protein ratio in group 2 was the lowest in the measurement with Kjel-dahl method. Conclusion The method used in group 2 that nerves were extracted by Triton X-100 and Sodium deoxycholate consecutively twice was the best in allogenic acellular peripheral nerve preparations.

Objective To investigate the expressions of HOXA11 and β-catenin proteins in colorectal serrated lesions and their roles in carcinogenesis. Methods A total of 252 cases of colorectal biopsy specimens in Shanxi Dayi Hospital from January 2012 to December 2016 were analyzed retrospectively, including 97 serrated lesions, 46 common adenomas, 109 adenocarcinomas, and 24 normal colorectal mucosa tissues were selected as controls. The expressions of HOXA11 and β-catenin proteins were detected by immunohistochemical EnVision method. Methylation of HOXA11 gene was detected by specific methylation polymerase chain reaction (MSP) in 25 paraffin-embedded adenocarcinoma tissues. Results In 97 serrated lesions, 29 (29.9％) occurred in the left colon;in 46 common adenomas, 27 (58.7％) occurred in the left colon;in 109 adenocarcinomas, 76 (69.7％) occured in the left colon. The difference of the occurrence location among three groups was statistically significant (χ2 = 34.75, P< 0.01). The heterotopic expression rate ofβ-catenin protein in serrated lesions, common adenomas and adenocarcinomas was significantly higher than that in normal mucosae [96.9％ (94/97), 82.6％ (38/46), 86.2％ (94/109) vs. 0 (0/24), P < 0.01]. The heterotopic expression of β-catenin protein was found in serrated lesions and the co-expression of cytoplasm and nucleus was found in common adenomas and adenocarcinomas. The normal expression rate of HOXA11 protein in serrated lesions, common adenomas and adenocarcinomas was lower than that in normal mucosae [33.0％ (32/97), 67.4％ (31/46), 48.6％ (53/109) vs. 100.0％ (24/24), all P< 0.05]. The methylation rate of HOXA11 gene was 84.0％ (21/25). Conclusion The ectopic expression of β-catenin in colorectal serrated lesions suggests that it is associated with serrated lesions, and the low expression of HOXA11 may be an early event in the carcinogenesis of serrated lesions.
