[Penile cancer with perineural invasion is more prone to postoperative recurrence].

Objective: To explore the correlation between perineural invasion and postoperative recurrence in patients surgically treated for penile cancer.

Methods: We conducted a retrospective analysis of the clinical data on 18 penile cancer patients surgically treated in our hospital from January 2018 to December 2021, 8 with postoperative recurrence (the recurrence group) and the other 10 without (the non-recurrence control group). We compared the two groups of patients in the age of onset, tumor-node-metastasis (TNM) stages, American Joint Committee on Cancer (AJCC) prognosis stages, surgical methods, perineural invasion and recurrence time.

[Biological and phylogenetic analysis of first isolate of Tahyna virus in China].

In 2006, the first Chinese Tahyna virus isolate (XJ0625) was obtained in Xinjiang province and human infection were found in the same region. In this study, cell culture, animal experiments, electron microscopy, immunofluorescence assay and cross neutralization tests were performed to see the cell susceptibility, animal pathogenicity, morphology and antigenic and other biological characteristics of XJ0625. In addition, molecular biology software was used to analyze the characteristics of molecular evolution.

[Effects of intrathecal escin and clonidine in the treatment of neuropathic pain in rats].

Objective: To investigate the effects of intrathecal escin and clonidine, used alone or in combination, in the treatment of neuropathic pain in rats and the possible mechanism.

Methods: Ninety-six male SD rats weighing 250-300 g were chronically implanted with lumbar intrathecal catheters. One week later, the left L5 and L6 spinal nerve roots were ligated to establish the model of spinal nerve ligation neuropathic pain (SNL).

Tahyna virus and human infection, China.

In 2006, Tahyna virus was isolated from Culex spp. mosquitoes collected in Xinjiang, People's Republic of China. In 2007, to determine whether this virus was infecting humans, we tested serum from febrile patients.

[Comparison of target controlled propofol infusion and sevoflurane inhalational anesthesia in laparoscopic cholecystectomy].

Objective: To compare the effects of propofol target controlled infusion (TCI) and sevoflurane inhalational anesthesia on the hemodynamics and postoperative recovery in patients undergoing laparoscopic cholecystectomy.

Methods: Sixty ASA IorII patients scheduled for laparoscopic cholecystectomy were randomized into propofol TCI group (group P) and sevoflurane inhalational anesthesia group (group S). In group P, TCI propofol was maintained after intubation until incision closure with the target concentration at 3 microg/ml.

[Acute normovolemic hemodilution combined with controlled hypotension in patients undergoing liver tumorectomy].

Objective: To evaluate the effects of acute normovolemic hemodilution (ANH) combined with controlled hypotension on reducing heterogeneous transfusion and safety during liver tumorectomy.

Methods: Thirty patients undergoing elective liver tumorectomy were randomly divided into 3 groups (10 each), namely ANH group (group A), ANH combined with controlled hypotension group (group B) and control group (group C). All the patients were anesthetized via endotracheal intubation.
