METHODS: Fifty-three patients with LC and 26 healthy control subjects were enrolled in the study. The intestinal permeability value is expressed as the percentage of polyethylene glycol (PEG) 400 and 3350 retrieval in 8-h urine samples as determined by high performance liquid chromatography. Serum TNF-α concentrations and urine NO metabolites were determined using an enzyme-linked immunosorbent assay (ELISA) and Greiss reaction method, respectively. RESULTS: The intestinal permeability index wassignificantly higher in patients with LC with ascites than in healthy control subjects or patients with LC without ascites (0.88 ± 0.12 vs 0.52 ± 0.05 or 0.53 ± 0.03, P 〈 0.05) and correlated with urine nitrite excretion (r = 0.98). Interestingly, the serum TNF-α concentration was significantly higher in LC without ascites than in control subjects or in LC with ascites (198.9 ± 55.8 pg/mL vs 40.9 ± 12.3 pg/mL or 32.1 ± 13.3 pg/mL, P 〈 0.05). Urine nitrite excretion was significantly higher in LC with ascites than in the control subjects or in LC without ascites( 1170.9± 28.7 μmol/L vs 903.1 ± 55.1 μmol/L or 956.7 ± 47.7 μmol/L, P 〈 0.05). COMCLUSIOM: Increased intestinal macromolecular permeability and NO is probably of importance in the pathophysiology and progression of LC with ascites, but the serum TNF-α concentration was not related to LC with ascites.展开更多

Methods: We retrospectively analyzed the clinical data of 32 patients with TSH developing into CSDH and reviewed related literature. Results: 16.7% of TSH developed into CSDH in this study. The time of evolution was from 22 to 100 days after head injury. All the patients were cured with hematoma drainage. Conclusions: TSH is one of the origins of CSDH. The clinical characteristics of TSH developing into CSDH follow that the ages of the patients are polarized, that the evolution often happens in the patients with small chronic hydromas and being treated conservatively, that the patients are usually injured deceleratedly and that the accompanying cerebral damage is often very mild.展开更多

Methods: From October 1988 to June 2002 a total of 358 patients with CSDH were treated with trepanation and drainage in our hospital. Among them 15 patients had recurrence of CSDH after operation. The data of the 15 patients were reviewed retrospectively. Results: Of the 15 patients, 13 were cured by retrepanation and redrainage, one cured by removal of hematoma by craniotomy with bone flap, and one, a 1 year old child, gave up reoperation due to severe encephalatrophy. Conclusions: Most CSDHs which recur after trepanation and drainage can be cured by retrepanation and redrainage. For the patients with repeated recurrence of CSDH removal of hematoma capsule can be considered. The causes of recurrence of CSDH are related to disease course, the thickness of hematoma capsule, the severity of encephalatraphy and whether the hematoma cavity is drained or irrigated completely, and operation methods.展开更多

Methods:Retrospective study was made on 135 patients with traumatic EDH admitted into our hospital from June 2002 to August 2005.Sixty-five patients were treated with mini-invasive negative pressure drainage (treatment group),70 patients with comparable condition used traditional craniotomy(control group).The mean time of operation,average days in hospital,expenditure and prognosis of two groups were recorded and analyzed. Results:There was no significant difference in therapeutic efficacy between two groups.Patients in treatment group had a shorter hospital stay and less expenditure than those in control group. Conclusion:Mini-invasive negative pressure drainage is simple,effective,economical and applicable to some traumatic EDH patients.展开更多

We attempt to make the surgical procedure less invasive by treating selected pediatric patients with trephination minicraniectomy. Methods: We retrospectively reviewed the clinical courses, radiological findings, surgical procedures, and prognoses of the pediatric patients who were treated in our departments for traumatic PFEDH from January 2010 to January 2015. Results: During this period, a total of 17 patients were surgically treated for PFEDH and 7 were managed with trephination mini-craniectomy for hematoma evacuation. The outcomes were good in all 7 patients as evaluated with Glasgow Outcome Score. There was no mortality in this series. The on average 30-month clinical follow-up showed that patients experienced satisfactory recoveries without complications. Conclusion: Our results suggest that trephination mini-craniectomy is a safe surgical technique for selected PFEDH patients with moderate hematoma volume and stabilized neurological functions. However, standard craniectomy is recommend when there are rapid deteriorations in patients' neurological functions or the hematomas are large and exerted severe mass effects.展开更多
