Objective To investigate the risk factors for post-traumatic hydrocephalus ( PTH) after traumatic brain injury ( TBI ) . Methods A retrospective case control analysis was made on the clinical data of 794 patients with acute TBI admitted to Shenzhen Second People's Hospital between January 2007 and January 2017. There were 639 males and 155 females, aged 1-90 years [(40. 5 ± 18. 6)years]. All patients were followed up for 1 years, and the patients were divided into PTH group (n=46) and non-PTH group (n=748) according to their prognosis. The following information including Glasgow coma score ( GCS ) on admission, pupil reflex, midline shift and cistern compression, subarachnoid hemorrhage ( SAH ) , operation method, decompressive craniectomy, hydrocephalus after operation, intracranial infection, timing of cranioplasty were analyzed using univariate analysis and Logistic regression. Results PTH occurred in 46 patients (5. 8％). Univariate analysis showed that GCS, midline shift, decompressive craniectomy, subdural effusion, timing of cranioplasty and SAH were significantly related to PTH (P<0. 05 or 0. 01). Logistic regression identified low GCS (OR=3. 778), decompressive craniectomy (OR=2. 508), subdural effusion (OR=2. 269), timing of cranioplasty (≥3 months)(OR=10. 478) and SAH (OR=23. 391) as the independent risk factors for PTH (P<0. 05 or 0. 01). Conclusion PTH is a common serious complication of traumatic brain injury, affected by low GCS, decompressive craniectomy, subdural effusion, delayed cranioplasty and SAH.

Objective To study the therapeutic effect of anti-CD80 bivalent antibody on mouse lu-pus nephritis and to explore the possible molecular mechanism. Methods A mouse model of lupus nephritis was established through intraperitoneal injection of 0. 5 ml of pristine in female C57BL/6J mice. Appearance of urinary protein and significantly increased levels of peripheral antinuclear antibody ( ANA) and anti-doub-le-stranded DNA ( anti-dsDNA) antibody in the fourth month after injection indicated that the mouse model was established successfully. Then the mice were divided into two groups including anti-CD80 bivalent anti-body intervention group (injected with 200μg of anti-CD80 bivalent antibody at day 1, 3, 5, 8 and 15, fol-lowed by three times of injection with an interval of one month) and model group ( injected with the same protein using the same strategy). A normal control group was set up accordingly. Albustix test paper was used to monitor the dynamic changes in mouse urinary protein. Flow cytometry was used to analyze the acti-vation of immune-related cells in spleen. Levels of autoantibodies ( ANA and anti-dsDNA) and levels of IFN-γ and IL-4 in serum were detected by indirect immunofluorescence assay. Renal tissue samples were an-alyzed with hematoxylin and eosin ( HE) staining and immunocomplex ( IC) assay. Results Urinary pro-tein level of the anti-CD80 bivalent antibody intervention group was significantly lower than that of the model group (P<0. 05). Activated macrophages, dendritic cells, neutrophils and B cells in spleen tissues of the anti-CD80 bivalent antibody intervention group were significantly less than those of the model group ( P<0. 05), and the numbers of CD4+ and CD154+ T cells were significantly less than those of the model group (P<0. 05). Positive rates and titers of ANA and dsDNA in serum samples of the intervention group were lower than those of the model group (P<0. 05). Levels of IFN-γand IL-4 in serum samples of the interven-tion group were decreased as compared with those of the model group (P<0. 05). HE staining and immuno-fluorescence assay showed that glomerular inflammatory injury and necrosis were alleviated and kidney im-mune complex deposition was reduced after anti-CD80 bivalent antibody intervention. Conclusion Anti-CD80 bivalent antibody specifically binds to the CD80 molecule on antigen presenting cell surface, blocks the CD80/CD28 co-stimulatory signaling pathway and down-regulates the body′s immune response, which al-leviates and reverses the lupus-like nephritis-induced pathological damages in mice.

Background:With the emergence of bacterial resistance,the efficacy of Helicobacter pylori(Hp)eradication therapy is decreasing in recent years. After the previous failed course of eradication therapy,the possibility of failure of re-eradication therapy is greater. Therefore,choosing the rescue therapy for Hp re-eradication is particularly important. Aims:To investigate the efficacy of levofloxacin-based triple therapy combined with probiotics as a rescue therapy for Hp re-eradication. Methods:A total of 192 patients with a previous failed course of standard triple therapy for Hp eradication were enrolled and randomly assigned into four groups. Group A:lansoprazole 30 mg + amoxicillin 1 000 mg + levofloxacin 200 mg bid for 14 days;group B:regimen of group A with the addition of bismuth potassium citrate 600 mg bid for 14 days;group C:bifidobacterium and lactobacillus triple live bacteria 2 000 mg tid for 14 days followed by regimen of group A for 14 days;group D:regimen of group A with the addition of bifidobacterium and lactobacillus triple live bacteria 2 000 mg tid for 14 days. At 4 weeks after end of treatment,Hp eradication was assessed by 13 C-urea breath test. Adverse effects during the course of treatment were recorded. Results:A total of 177(92. 2% )patients completed the study,the completion rates in group A,B,C and D were 87. 5%(42 / 48),83. 3%(40 / 48),97. 9%(47 / 48)and 100% , respectively;the completion rates in group C and D were significantly higher than those in group A and B(P < 0. 05). By intention-to-treat(ITT)analysis,the eradication rates of group A,B,C and D were 60. 4% ,68. 8% ,81. 3% and 83. 3% ,respectively;the eradication rates in group C and D were significantly higher than that in group A(χ2 = 5. 042, P = 0. 045;χ2 = 6. 235,P = 0. 013). By per-protocol(PP)analysis,the eradication rates of group A,B,C and D were 69. 0% ,82. 5% ,83. 0% and 83. 3% ,respectively;no statistically significant differences were found among the four groups(P > 0. 05). Adverse effects included constipation,taste distortion,bloating and anorexia,the incidences of adverse effects in group A,B,C and D were 79. 2% ,95. 8% ,29. 2% and 22. 9% ,respectively;the incidences in group C and D were significantly lower than those in group A and B(P < 0. 05). Conclusions:Levofloxacin-based triple therapy combined with bifidobacterium and lactobacillus triple live bacteria can decrease the adverse effects of traditional triple and quadruple therapies and improve the patient compliance,thus increases the efficacy of rescue therapy for Hp re-eradication.
