Objective: To explore the advantages and effectiveness of preoperative 3D printing planning technology combined with orthopedic surgical robot-assisted screw placement in the minimally invasive treatment of pelvic fractures compared to orthopedic surgical robot-assisted screw placement alone.
Methods: A retrospective analysis of the clinical data of 29 patients with unstable pelvic fractures treated with orthopedic surgical robot-assisted percutaneous screw fixation from July 2021 to August 2023 was conducted. Among them, 13 patients who underwent preoperative 3D printing technology for screw planning were assigned to the experimental group, and the remaining 16 patients were assigned to the control group.
[Prevalence of occult hepatitis B virus infection and its phylogenetic features among mother-teenager pairs].

March 2013
Article Synopsis
- The study aimed to investigate the prevalence of occult hepatitis B virus (OBI) in a group of mothers and their teenage children, focusing on HBV S gene variations.
- Researchers followed up with 102 mother-teen pairs after collecting questionnaires and blood samples to detect HBV infection levels using various methods like ELISA and PCR.
- Results showed a higher prevalence of OBI in mothers (10%) compared to teenagers (2%), and different genotypes were identified, with a notable proportion of genotype-C strains present in occult HBV cases.

Objective: To compare the difference of effects on hearing injury between punching machine noise and steady state noise.
Methods: The subjects of present study were 100 workers, included 38 workers exposed to punching machine noise from forging shops and 62 workers exposed to steady state noise from drawbench or abrasive dust workshops. The individual noise dosimetries were used to detect noise that workers exposed, and cumulative noise exposure (CNE) was then calculated.
[Expression and significance of RhoA and NF-ΚB in human gastric carcinoma].

April 2011
Article Synopsis
- The study aims to investigate the expression of RhoA and NF-κB in gastric carcinoma and how they relate to various clinical and pathological features, as well as to identify prognostic factors affecting long-term survival of patients.
- Tissue samples from 189 gastric carcinoma cases, along with adjacent and normal tissues, were analyzed using immunohistochemistry to quantify RhoA and NF-κB expression levels.
- Results showed significantly higher expression levels of both proteins in gastric carcinoma compared to adjacent and normal tissues, with RhoA and NF-κB associated with factors like depth of invasion and lymph node metastasis; ultimately identifying NF-κB expression, lymph node metastasis, and depth of invasion as independent prognostic factors
