Objective To investigate the relationship between Helicobacter pylori (Hp) infection and disease severity and pathological type of intestinal polyps in inpatients. Methods The data of 303 inpatients with intestinal polyps in the hospital from August 2022 to February 2025 were collected and analyzed. The clinical characteristics of patients were analyzed, and the influencing factors of pathological types of polyps were explored. Results Among the 303 inpatients with intestinal polyps, there were 135 Hp positive cases and 168 Hp negative cases. The number of polyps, maximum polyp diameter, number of ileocecus/ascending colon/transverse colon polyps, number of descending colon/sigmoid colon/rectal polyps and adenomatous polyps in the Hp-positive group were higher than those in the Hp-negative group (P<0.05). Multivariate logistic regression analysis indicated that age [OR (95%CI)=1.03 (1.01-1.05)] and positive Hp[OR (95%CI)=2.61 (1.62-4.20)] were independent risk factors of occurrence of adenomatous polyps (P<0.05). ROC curve results revealed that the AUCs of age, positive HP and combination in the diagnosis of adenomatous polyps were 0.574, 0.608 and 0.646, and the 95%CI values were 0.509-0.638, 0.545-0.672 and 0.584-0.708 respectively. The efficiency of combination of the two indexes was higher than that of single diagnosis. Conclusion Hp infection is associated with disease severity in inpatients with intestinal polyps, and it may be involved in the occurrence and development of adenomatous polyps.

The brain pericyte is a unique and indispensable part of the blood-brain barrier (BBB), and contributes to several pathological processes in traumatic brain injury (TBI). However, the cellular and molecular mechanisms by which pericytes are regulated in the damaged brain are largely unknown. Here, we show that the formation of neutrophil extracellular traps (NETs) induces the appearance of CD11b⁺ pericytes after TBI. These CD11b⁺ pericyte subsets are characterized by increased permeability and pro-inflammatory profiles compared to CD11b^- pericytes. Moreover, histones from NETs by Dectin-1 facilitate CD11b induction in brain pericytes in PKC-c-Jun dependent manner, resulting in neuroinflammation and BBB dysfunction after TBI. These data indicate that neutrophil-NET-pericyte and histone-Dectin-1-CD11b are possible mechanisms for the activation and dysfunction of pericytes. Targeting NETs formation and Dectin-1 are promising means of treating TBI.

Objective:To determine the difference of curative effects of gamma knife treatment and microsurgery on patients with recurrent trigeminal neuralgia (TN) after microvascular decompression (MVD).Methods:From January 2011 to December 2018, 65 patients with recurrent TN after MVD were enrolled in the study; 40 patients received gamma knife treatment and 25 patients received secondary microsurgical treatment. Barrow Neurological Institute (BNI) proposed pain grading was used to evaluate the efficacies right after treatment and 3 years after follow-up in all patients, and grading I-III was defined as pain relief.Results:Patients received gamma knife treatment had pain relief within 4-10 weeks of treatment and disappeared gradually; patients received secondary microsurgical treatment had disappeared facial pain immediately after waking up from anesthesia or completely alleviated facial pain within one week of treatment. Up to 3 years after surgery, follow-up results showed that 17 patients (68.0%) in the gamma knife treatment group had pain relief, and 16 patients (94.1%) in the microsurgical treatment group had pain relief; the difference in pain relief rate between the two groups was statistically significant ( χ2=4.100, P=0.043). Facial numbness was noted in the gamma knife treatment group, with an incidence of 24.0%; in the microsurgical treatment group, hemiplegia was noted in one patient and facial numbness was noted in the left ones, with complication rate of 29.4%; and the difference in complication rate between the two groups was not statistically significant ( χ2=0.010, P=0.921). Conclusion:For patients with recurrent TN after MVD, secondary microsurgical treatment and gamma knife treatment are safe and effective, among which secondary microsurgical treatment is more effective than gamma knife treatment.

Objective To study the factors influencing prognosis in the patients with recurrent glioblastoma muhiforme (GBM) and to investigate the effect of retreatemt.Methods The retrospective analysis method was adopted to collect the clinical and follow up data in 36 cases of recurrent GBM retreatment in the neurosurgery department of this hospital from March 2008 to March 2013.The prognosis influencing factors were analyzed.Results The univariate analysis results showed that the gender,resection degree,treatment mode and initial scheme had the influence on the progression free survival(P＜0.05).The resection degree had an impact on the overall survival(P＜0.05).The multivariate analysis results showed that KPS score,resection degree and treatment mode had effect on the progression free survival(P＜0.05).The resection degree had an influence on the overall survival (P＜0.05).Conclusion If the patients with recurrent GBM still hasthe chance of operation whole excision,the re-treatment can reach the effect for relieving the symptoms,improving the quality of life and prolonging the survival period.

Objective To investigate the clinical effect of using uninterrupted vacuum sealing drainage combined with routine debridement and pedicled periosteal flap sealing frontal sinusitis in treating frontal sinusitis after craniotomy.Methods The clinical data in 31 cases of frontal sinusitis after craniotomy in our hospital from January 2006 to December 2014 were retrospectively analyzed.Seventeen cases adopted simple debridement and drainage treatment and 14 cases were treated with continuous vacuum sealing drainage combined with routine debridement treatment.Postoperative follow up lasted over 1 year.Results In simple debridement and drainage,12 cases were cured,the other 5 cases recurred after operation,and the cure rate was 70.6 ％.But in the continuous vacuum sealing drainage combined with routine debridement treatment,14 cases were cured,no case recurred after operation,and the cure rate was 100％.Therefore,the cure rate of continuous vacuum sealing drainage treatment combined with routine debridement was higher than that of simple debridement and drainage treatment(P＜0.05).Conclusion Adopting vacuum sealing drainage combined with routine debridement and pedicled periosteal flap sealing frontal sinusitis can promote the infection focus clearance and wound healing,and increases the cure rate.

Objective To analyze TORCH infection situation in 6 027 cases of pregnant women,puerperae and neonates.Methods The TORCH IgM and IgG was detected by using ELISA for 6 027 cases of pregnant women,puerperae and neonates,and the positive rates of the antibodies to variant TORCH pathogens were analyzed.Results The positive rates of HSVⅠ-IgM,HSVⅡ-IgM,RV-IgM,TOXO-IgM and CMV-IgM were 0.02%,0.02%,0.12%,0.12% and 0.20% respectively.The positive rates of HSVⅠ-IgG,HSVⅡ-IgM,RV-IgM,TOXO-IgM,and CMV-IgM were 63.32%,13.31%,52.83%,12.68% and 58.57% respective-ly.Positive rate of CMV-IgM in neonates was higher than that in pregnant women,the difference was statistically significant(P <0.05).There were totally 28 cases of neonataes detected with acute CMV infection.Conclusion TORCH screening in pregnant women,puerperae and neonates helps the detection of infection disease in perinatal period.
