PurposeTo investigate the effect of gasoline on the skin barrier function.MethodsA rat skin model in vitro was used in this study. The amount of 3H-water penetrated throught the skin was applied as the index of evaluating the barrier function.ResultsThe results showed that the amount of 3H-water was not obviously increased in those exposed to gasoline for 0.5,1 and 2 h(P > 0.05), but the 3H-water penetration amount through the skin increased linearly with the time. In the group exposed to gasoline 4 h, the 3H-water penetration amount through the skin was significantly higher than that in the control group (P 0.05). The skin barrier function of the group (expopsed to gasoline 4 h) was disrupted.Conclusions Gasoline may disrupt the skin barrier function. Gasoline would remove the lipids within the intercellular domains of the stratum corneum and then lead to damage the skin.

The clinical characteristics of patients who presented in poor clinical grade due to ruptured middle cerebral artery aneurysms (MCAAs) associated with large sylvian hematomas (SylH) were analyzed and an ingenious designed prophylactic hinged craniectomy was introduced. Twenty-eight patients were graded into Hunt-Hess grades IV-V and emergency standard micro-neurosurgeries (aneurysm clipping, hematoma evacuation and prophylactic hinged craniectomy) were performed, and their clinical data were retrospectively analyzed. 46.43% of the patients reached encouraged favorable outcomes on discharge. The favorable outcome group and the poor outcome group significantly differed in terms of patients' anisocoria, Hunt-Hess grade before surgery, extent of the midline shift and time to the surgery after bleeding (P<0.05). There were no significant differences in age, sex, volume and location of the hematoma, size of aneurysm between the favorable and poor groups (P>0.05). However, ingenious designed prophylactic hinged craniectomy efficiently reduced the patients' intracranial pressure (ICP) after surgery. It was suggested that preoperative conditions such as Hunt-Hess grading, extent of the midline shift and the occurrence of cerebral hernia affect the prognosis of patients, but time to the surgery after bleeding and prophylactic hinged craniectomy are of significant importance for optimizing the prognosis of MCAA patients presenting with large SylH.

OBJECTIVETo search the forming cause and the correlation between the clinical phenotype and chromosome band by the cytogenetic analysis on a case of ring chromosome 21 syndrome.

METHODSIdentification and location of 21 ring chromosome were performed with the G-banding, C-banding, N-banding, high-resolution banding and fluorescence in situ hybridization (FISH) techniques.

RESULTSIt was found that the karyotypes of the patient's parents are normal. The patient's karyotype is 46,XY, r(21)[91]/46,XY,r(21;21)(p11q22.3;p11q22.3) [5]/45,XY,-21[4].

CONCLUSIONThe clinical phenotype of ring chromosome 21 syndrome is related to the deletion of distal segment of 21q, and the abnormal sexual development of male is related with the deletion of 21q22.3.

OBJECTIVETo observe the protection of Qingyuan Shenghua Decoction (QSD) on multiple organs of sepsis patients after bone trauma, and to preliminarily explore its mechanism.

METHODSTotally 60 sepsis patients after bone trauma were randomly assigned to the treatment group and the control group according to random digit table, 30 in each group. All patients received routine Western medical treatment. Patients in the treatment group additionally took QSD or were nasally fed with QSD, one dose per day for 1 week. Changes of WBC, oxygenation index (PaO2/FiO2), serum creatinine (SCr), total bilirubin (TBIL), aspartate aminotransferase (AST), fibrinogen (FIB), D-dimer (DD), activated partial thromboplastin time (APTT), pro-calcitonin (PCT), C-reactive protein (CRP), heart rate (HR), mean arterial pressure (MAP), intra-abdominal pressure, scores for Acute Physiology and Chronic Health Evaluation II (APACHE II), sequential organ failure assessment (SOFA) scores were observed before treatment and on day 1, 3 and 7 after treatment.

RESULTSCompared with the control group at the same time point, MAP increased at post-treatment day 1 and 3; CRP, APTT, HR, SCr, TBIL, AST, intra-abdominal pressure at post-treatment day 3 obviously decreased in the treatment group (P < 0.05, P < 0.01). WBC, SOFA scores, PCT, CRP, APACHE II, APTT, D-D, HR, SCr, TBIL, AST and intra-abdominal pressure significantly decreased; FIB, MAP and PaO2/FiO2 obviously increased at post-treatment day 7 (P < 0.05, P < 0.01).

CONCLUSIONQSD had good protective effect on multiple organ function in sepsis patients after bone trauma, and its mechanism might be related with effectively clearing endotoxin, alleviating inflammatory reactions, and fighting against coagulation dysfunction.

Objective To observe the effect of different doses of pregabalin and self-control analgesia (PCA) in early postoperative pain in orthopedic lumbar spine surgery patitens.Methods A total of 54 patients with lumbar spinal canal stenosis lumbar vertebrae decompression surgery were randomly divided into high,middle and low dose groups,each group 18 cases.High,middle and low dose groups were orally given pregabalin 300,150,75 mg at 2 h before anesthesia.The patient controlled analgesia (PCA) was used after surgery.The visual analogue score (VAS) at 2,6,12,24 h after surgery,the analgesia drug dosage within 24 h of self-control,incidence of adverse drug reactions were observed in two groups.Results The VAS at 2 h after surgery in high,middle and low dose groups were 3.72 ± 1.27,3.67 ± 1.14,4.78 ± 1.31,with significant difference between high dose and low dose groups(P ＜0.05).The VAS at 6 h after surgery in high,middle and low dose groups were 3.06 ± 0.80,3.28 ± 1.49,4.00 ± 0.69,with significant difference between high dose and low dose groups (P ＜ 0.05).The VAS at 12 h after surgery in high,middle and low dose groups were 2.28 ± 0.67,3.11 ± 1.28,3.33 ± 0.84,with significant difference (P ＜ 0.05).The VAS at 24 h after surgery in high,middle and low dose groups were 2.17 ±0.62,2.83 ± 1.10,2.83 ±0.71,with no significant difference (P ＞0.05).There were 1 case of dizziness,nausea and vomiting,1 case of somnolence,1 case of nausea and vomiting,with the incidence of 16.67％ (3/18 cases).There was 1 case of nausea and vomiting respectively in middle dose and low dose group,with the incidence of 5.56％ (1/18 cases).There was no significant difference in the incidence among three groups (P ＞ 0.05).Conclusion Lyrica drugs prior to application in orthopedic surgery,early postoperative analgesic effect is good,with low incidence of adverse reactions,300 mg of drug delivery in advance can be a good solution.

Objective To evaluate the feasibility and advantages ofmidfrontai keyhole approach for treatment of hypertensive ventricular hemorrhage cast. Methods Thirty patients with hypertensive ventricular hemorrhage cast were randomized into 2 groups to receive ventricular drainage (group A) or microsurgical hematoma elimination through midfrontal keyhole approach (group B). The clinical outcomes of the patients were assessed according to the Glasgow Outcome Scale (GOS) after 3-6 months of follow-up. Results IngroupA, 6 patients had GOS grade l, 6 had grade 2-3, and 3 had grade 4-5 outcomes. In group B, 1 patient had GOS grade 1, 2 had grade 2-3, and 12 had grade 4-5 outcomes. The patients in group B had significantly better outcomes than those in group A. Conclusion Microsurgical hematoma elimination through the midfrontal keyhole approach produces better therapeutic effect than ventrieular drainage in the treatment of hypertensive ventricular hemorrhage cast.

Objective To investigate the risk factors of recurrent stroke in IS patients with CHF.Methods A total of 235 elderly IS patients with CHF admitted to Northern Jiangsu People's Hospital from January 2021 to January 2023 were enrolled in this study.According to LVEF clas-sification,they were divided into reduced ejection fraction HF group(HFrEF,LVEF＜40％,80 patients),intermediate ejection fraction HF group(HFmrEF,40％≤LVEF＜50％,57 patients),and preserved ejection fraction HF group(HFpEF,LVEF≥50％,98 patients).After all of them were followed up for 12 months,the patients with recurrent IS were assigned into the recurrent IS group(42 patients)and those without into the non-recurrent IS group(193 patients).Their gener-al data,laboratory results,clinical endpoint events and other indicators were compared in the above groups.Multivariate logistic regression analysis was applied to identify the related risk fac-tors for recurrent stroke in elderly patients with CHF and IS.Results There were significant differences in women ratio,age,history of smoking and drinking,peripheral vascular disease,RBC count,hemoglobin,hematocrit,LDL-C,prothrombin time,international standardized ratio,BNP,LVEF,LVEDD and LVESD among the three groups(P＜0.05,P＜0.01).The recurrent IS group had obviously larger proportion of diabetes mellitus,longer thrombin time,and larger LAD and RAD when compared with the non-recurrent IS group(P＜0.05,P＜0.01).Multivariate logistic regression analysis showed that diabetes(OR=0.251,95％CI:0.1 96-1.494,P=0.031)and LAD(OR=1.085,95％CI:1.008-1.169,P=0.031)were independent risk factor for recurrent stroke in elderly patients with CHF and IS.There were no significant differences in follow-up period and incidence of clinical endpoints among the three groups(P＞0.05).Conclusion Diabetes and LAD are independent risk factors for recurrent IS in elderly CHF patients with IS.

Objective To explore the influences of family-centered health education on compliance of segregation in children with respiratory infectious disease. Methods The patients of observation group received family-centered health education and included 247 children with respiratory infectious disease who were hospitalized in Hu′nan Children′s Hospital from August to December in 2014 and their parents. The patients of control group received normal health education and included 285 children with respiratory infectious disease who were hospitalized from January to July in 2014 and their parents. The compliance of segregation of the children and their parents were compared between two groups. Results The cognition of the awareness, category and requirement of the segregation, as well as parents′ effective segregate practice of the observation group were significantly higher than that of the control group (χ2 =38. 7,57. 71,30. 36;P<0. 01). Conclusions Family-centered health education can highly improve the compliance of segregation in children with respiratory infectious disease. It can also prevent cross infection and ensure children′s health.

OBJECTIVETo compare differences of angiogenesis among collagen- chitosan, collagen-sulfonated carboxymethyl chitosan porous scaffolds and acellular dermal matrix after these three different scaffolds with silicone membrane were transplanted on the wounds of full thickness burn, and the wound repair of different scaffolds with epidermis grafting on.

METHODSAngiogenesis in different dermal scaffolds, the wound surface and epidermis survival were observed in 1, 2, and 3 weeks after the three different scaffolds were respectively transplanted on wounds of full thickness burn with debridement in 6 Bama miniature pigs (total 18 pigs in 3 groups). At the same time, CD34 positive signals (neo-forming microvessels) were detected by immunohistochemical staining. The wounds without any scaffold transplantation were studied as the control.

RESULTSAngiogenesis had been fundamentally finished in 2 weeks after implantation of collagen- sulfonated carboxymethyl chitosan porous scaffold. And fundamental angiogenesis in collagen- chitosan porous scaffolds and acellular dermal matrix needed at least 3 weeks. Neo-forming micro-vessels perpendicular to wound beds with these three different scaffolds were more than those in the control wounds without scaffold. CD34 positive signals (neo-forming micro-vessels) were significantly higher in wounds at the second week than those in wounds at the first week. And those in wounds at the third week were significantly higher than those in wounds at the second week in all wounds with different scaffold transplantations and the control wounds. CD34 positive signals in the group of sulfonated carboxymethyl chitosan porous scaffold on the 1st, 2nd and 3rd week after the scaffold transplantation were significantly higher than those corresponding signals in the other three groups. Epidermis on the sulfonated carboxymethyl chitosan porous scaffold which had been transplanted on burn wound for 1 week could survive perfectly, however, epidermis on the collagen- chitosan porous scaffold or acellular dermal matrix could not survive until these two scaffolds had been transplanted on the burn wounds for at least 2 weeks.

CONCLUSIONSThese three different scaffolds could repair the full thickness skin defects caused by burn, and angiogenesis of sulfonated carboxymethyl chitosan porous scaffold is the best.
