With the development of underground rail transit, the concept of intelligent tunnel construction has been proposed and promoted. High-quality networking during tunnel construction is a prerequisite for this, making it highly urgent to establish networking during tunnel construction. When studying intra-tunnel networking, it is necessary to consider the propagation characteristics of radio waves in the tunnel.

- The study investigates immune persistence after switching from trivalent oral poliovirus vaccine (tOPV) to a new immunization schedule (IPV and bOPV) since 2016.
- Blood samples were collected from 1104 participants at various ages to measure antibody levels against polioviruses.
- Results showed that while type 1 and type 3 antibody rates were similar across groups, the 2-specific antibody rates were much higher in the IPV-IPV-tOPV group compared to others, indicating some schedules did not effectively maintain immunity against poliovirus type 2.
To provide a basis for further optimization of the polio sequential immunization schedule, this study evaluated the effectiveness of booster immunization with one dose of bivalent oral poliovirus vaccine (bOPV) at 48 months of age after different primary polio immunization schedules. At 48 months of age, one dose of bOPV was administered, and their poliovirus types 1-3 (PV1, PV2, and PV3, respectively)-specific neutralizing antibody levels were determined. Participants found to be negative for any type of PV-specific neutralizing antibody at 24, 36, or 48 months of age were re-vaccinated with inactivated polio vaccine (IPV).

Objective: To determine the prevalence of herpes simplex virus (HSV) and its correlates among HIV/AIDS patients in a county of Shanxi.
Methods: All HIV-infected patients in a county in Shanxi province who were receiving antiretroviral treatment (ART) were included in this study. Participants were interviewed using standard questionnaires.

Objective: To assess the adherence, immunologic and survival responses in HIV-infected patients receiving free antiretroviral therapy (ART).
Methods: All adult HIV-infected patients in Wenxi county who started antiretroviral treatment (ART) between 01 July 2001 and 31 December 2006 and aged above 18 years were included in this study. Epidemiological survey and laboratory tests were performed before, 0.
Objective: To investigate the value of using an AMACR/34betaE12/p63 cocktail and double-staining for the diagnosis of small focal protatic carcinoma and precarcinomatous lesions.
Methods: A total of 130 consecutive cases were examined over a 3-month period, including 105 prostate needle biopsy samples, 6 radical prostatectomy specimens and 19 benign prostatic hyperplasia specimens which were excised transurethra or above pubis. 262 paraffin blocks of all the 1030 ones were stained with hematoxylin and eosin and by immunostains for AMACR, 34betaE12, p63, and an antibody cocktail comprising all the three with double-chromogen reaction.
