Objective To summarize the therapeutic effect of recombinant human growth hormone and early enteral nutrition in severely burned patients. Methods 35 cases were randomly divided into group EN and group PN.Group EN was treated with early enteral nutrition(EEN) and recombiant human growth hormone(rhGH) ,while group PN was given parenteral nutrition. The plasma levels of pre-albumin (PA), C-reactive protein (CRP) , tunmor necrosis factor α(TNFα) ,fasting blood glucose(FBG) were measured after burn injury. Comparision was made in length of hospital stay, wound healing time,incidence of burn sepsis, gastrointestinal stress ulcer bleeding and enteral nutrition intoleranc. Results Incidence of burn sepsis,gastrointestinal stress ulcer bleeding and enteral nutrition intoleranc in group EN were significantly lower than those of group PN(P ＜ 0.05). The serum levels of CRP、TNFα、FBG in group EN were significantly lower than those of group PN (P ＜ 0.05). The serum PA was decreased at all times in two periods and was markedly decreased in group EN(P ＜0.05). Length of hospital stay and the healing time of donor site, deep partial thickness burn wound, skin transplantion area were significantly shortened in group EN compared with group PN. Conclusion Early enteral nutrition was beneficial for the improving of nutrition state of the burn patients,and the reduction of the incidence of burn sepsis and the hospitalization time.

OBJECTIVETo review the influencing factors of the early complication after carotid endarterectomy (CEA).

METHODSRetrospective analysis of clinical data of 509 cases received CEA in Xuan Wu Hospital of Capital Medical University, Liaocheng People's Hospital and Dalian Central Hospital from January 2001 to December 2011. There are 422 male patients and 72 female patients among the 494 patients, 15 patients underwent CEA by stages. The patients were between 35-84 years old,and the mean age was (64 ± 9) years. The complications within 30 days after CEA were analyzed, and find the risk factors for the major adverse events. Chi-square analysis was performed to analyze the correlation between the each variable of the basic characteristics of population, clinical features and intraoperative data and early adverse events after CEA. Logistic regression analysis was used to assess the relationship between a variety of factors and the postoperative complications within 30 days.

RESULTSTechnical complete rate of 98.6%, 7 cases of near-total occlusion patients could not been recanalized. Major complications in 30 days after CEA occurred in 20 cases (3.9%), including 6 cases of deaths (1.2%), 9 cases of cerebral infarction (1.8%) and 5 cases of cerebral hemorrhage (1.0%). Secondary complications occurred in 120 cases (23.6%). Univariate analysis showed modified Rankin scale (mRS) ≥ 3 on the incidence of early postoperative complication had significantly difference (χ² =20.517, P < 0.01), multivariate logistic regression analysis revealed that smoking (OR=2.667, 95% CI: 1.048-6.791, P=0.040) and mRS ≥ 3 (OR=8.690, 95% CI: 3.279-23.031, P=0.000) were the significant predictors of 30 days of the end event.

CONCLUSIONThe complications after CEA are uncommon, the security is proved. Smoking and mRS ≥ 3 can increase the risk of CEA.

Objective:To evaluate the diagnosis and treatment of abdominal cocoon.Methods:The clinical data of 8 patients with abdominal cocoon in our hospital from Jan 2015 to Dec 2021 were retrospectively reviewed including clinical and imaging manifestations, treatment and follow-up.Results:One case was asymptomatic, and the other 7 cases suffered from recurrent abdominal pain with complete or incomplete intestinal obstruction. The median course of disease was 6 months (15 days to 40 years). Six cases underwent laparcoscopic cocoon membrane resection and intestinal adhesion lysis, of which 2 cases underwent laparotomy, one case was converted to open surgery, 4 cases underwent concomitant appendectomy. Follow-up ranged from 3 to 69 months, there were 2 cases complicating early inflammatory intestinal obstruction, 1 case suffred wound fat liquefaction and infection, 1 case with a colic 5 months after operation, and the others were doing well.Conclusions:The clinical characteristics of abdominal cocoon disease are not typical. Surgery is the main treatment. The prognosis of the disease is generally fair.

Endogenously eliminating the hematoma is a favorable strategy in addressing intracerebral hemorrhage (ICH). This study sought to determine the role of retinoid X receptor-α (RXR-α) in the context of hematoma absorption after ICH. Our results showed that pharmacologically activating RXR-α with bexarotene significantly accelerated hematoma clearance and alleviated neurological dysfunction after ICH. RXR-α was expressed in microglia/macrophages, neurons, and astrocytes. Mechanistically, bexarotene promoted the nuclear translocation of RXR-α and PPAR-γ, as well as reducing neuroinflammation by modulating microglia/macrophage reprograming from the M1 into the M2 phenotype. Furthermore, all the beneficial effects of RXR-α in ICH were reversed by the PPAR-γ inhibitor GW9662. In conclusion, the pharmacological activation of RXR-α confers robust neuroprotection against ICH by accelerating hematoma clearance and repolarizing microglia/macrophages towards the M2 phenotype through PPAR-γ-related mechanisms. Our data support the notion that RXR-α might be a promising therapeutic target for ICH.
