Objective To investigate the methods and the therapeutic effects of groin flap and stylus recurrent branch of radial artery flap for the repair of severely contracture of the first web space. Methods From March 2007 to six 2009,45 patients with severely contracture of the first web space received treatment of groin flaps and stylus recurrent branch of radial artery flaps, with 6 to 12 months clinical observation. Among then, 33 patients received treatment of groin flaps, 12 patients received treatment of stylus recurrent branch of radial artery flaps, and 28 patients received the first web space widening as well as functional reconstruction of thumb abduction. Results Most of the flaps healed by first intention but also with distal necrosis for 3 stylus recurrent branch of radial artery flaps and 1 groin flap. And the weth of the first web space of all patients were more than 90% of comparison. From clinical observation,function of opposition recovered well. While some groinflaps got a litte fat and clumsy .The color of most flaps was as similar as normal besides, some groin flaps occurrenced pigmentation. Conclusion Children and adults below 50 yesrs should choose the groin flap, and aged people and adults more than 50yesrs shuould choose the stylus recurrent branch of radial artery flap firstly.

Objective The purpose of this study is to explore the clinical value of CT angiography( CTA) in the diagnosis of multiple intracranial aneurysms.Methods The data of CTA and DSA from 74 patients with multiple intracra-nial aneurysms from July 2011 to March 2015 were reviewed retrospectively.Results One hundred seventy-seven aneu-rysms were detected by DSA, and 175 aneurysms were detected by CTA.Among the aneurysms identified by CTA, 4 aneu-rysms were false positive and the correct detection rate of CTA was 96.6%.One hundred sixty-five aneurysms identified by CTA were confirmed by DSA and the correct diagnostic rate of CTA was 96.5%.CTA failed to detect 6 aneurysms and mis-diagnosed 10 aneurysms.Conclusions The correct detection rate and diagnostic rate of CT angiography ( CTA) in multiple intracranial aneurysms is relatively high.But previous surgery, spasm of the vessels, the size and number of aneurysms, radiologists'experience can influence the accuracy of ( CTA) in the diagnosis of multiple intracranial aneurysms, indicating that we should combine CTA with DSA to avoid the misdiagnosis and missed diagnosis.

OBJECTIVETo introduce the Ages and Stages Questionnaires, Third Edition (ASQ-3), to China, created ASQ-Chinese (ASQ-C) and carried out studies of its national norm and the psychometrical properties in the children aged 1-66 months in the mainland of China in collaboration with the author of the ASQ System and under the authorizations from its publisher on translation, researches, publication and distribution of the ASQ-3.

METHODThe ASQ-3 questionnaires were translated and adapted into a Simplified Chinese version, the ASQ-C, with six steps such as translation, back-translation and adaptation and so on to ensure consistency with the core of the original document and to have the cultural relevance in China.A stratified cluster sampling method was utilized to recruit children aged 1-66 months with respect to demographic characteristics such as the proportion of population in each administrative region and in urban and rural areas and so on that are representative of 2010 China census data.A sample size of over 200 was collected for each ASQ-C age interval.Children were excluded from the normative sample who (1) are from communities or villages at an elevation of 2 000 m or above and(or) where simplified Chinese is not the official language, or (2) had been diagnosed as having a developmental delay by any authoritative organizations.The national normative sample for the ASQ-C had a total sample size of 4 452, sample size within each age interval ranged from 218 to 227, including 2 230 male cases and 2 222 female cases, 2 236 urban cases and 2 216 rural cases.A convenience sample was recruited from the normative sample to examine inter-rater reliability and test-retest reliability in all six administrative regions.Researchers completed the ASQ-C on the same child with their parents for 162 children for inter-rater reliability(the size of each ASQ-C age interval was 5-9); parents of 168 children completed another age-appropriate ASQ-C for test-retest reliability during 10-15 days after they completed the normative ASQ-C(The size of each ASQ-C age interval is 6-10). Another convenience sample was recruited from the follow-up of low birth weight infants for the concurrent validity of the ASQ-C in comparison with the Beijing Gesell.Parents of 198 children completed age-appropriate ASQ-C and professional administered to the children with the Beijing Gesell.In the ASQ-C norm and test-retest reliability, parents completed the age-appropriate ASQ-C, independently or with needed assistance. In inter-rater reliability, researchers completed the same ASQ-C after parents. In validity test, after parents completing age-appropriate ASQ-C, professional tested children with the Beijing Gesell.Data were analyzed using SPSS version 13.0 software.The mean and standard deviation of the national normative sample were calculated, reliability and validity of the ASQ-C was examined.

RESULTThe demographic characteristics of this Chinese sample match the 2010 China census data on gender, urban or rural location, and family income.All 20 intervals of the ASQ-C were standardized on 21 national normative samples.Cronbach's alpha coefficient for the whole measure was 0.8.The Pearson correlation coefficient between the ASQ-C total scores of the two raters was 0.8.The Pearson correlation coefficient between the ASQ-C total scores of the two times was 0.8 (all P<0.000 1). The sensitivity of ASQ-C was 87.50% and the specificity of ASQ-C was 84.48%.The percentage of the agreement between the ASQ-C and the Beijing Gesell was 84.74%.

CONCLUSIONThese findings indicate that the ASQ-C is a reliable and valid measure with a representative national sample aged 1-66 months.It can be used to screen and monitor the development of children in the mainland of China.

Background: and Purpose The optimal management of patients with acute basilar artery occlusion (BAO) is uncertain. We aimed to evaluate the safety and efficacy of endovascular thrombectomy (EVT) compared to medical management (MM) for acute BAO through a meta-analysis of randomized controlled trials (RCTs). Methods: We performed a systematic review and meta-analysis of RCTs of patients with acute BAO. We analyzed the pooled effect of EVT compared to MM on the primary outcome (modified Rankin Scale [mRS] of 0–3 at 3 months), secondary outcome (mRS 0–2 at 3 months), symptomatic intracranial hemorrhage (sICH), and 3-month mortality rates. For each study, effect sizes were computed as odds ratios (ORs) with random effects and Mantel-Haenszel weighting. Results: Four RCTs met inclusion criteria including 988 patients. There were higher odds of mRS of 0-3 at 90 days in the EVT versus MM group (45.1% vs. 29.1%, OR 1.99, 95% confidence interval [CI] 1.04–3.80; P=0.04). Patients receiving EVT had a higher sICH compared to MM (5.4% vs. 0.8%, OR 7.89, 95% CI 4.10–15.19; P<0.01). Mortality was lower in the EVT group (35.5% vs. 45.1%, OR 0.64, 95% CI 0.42–0.99; P=0.05). In an analysis of two trials with BAO patients and National Institutes of Health Stroke Scale (NIHSS) <10, there was no difference in 90-day outcomes between EVT versus MM. Conclusion In this systematic review and meta-analysis, EVT was associated with favorable outcome and decreased mortality in patients with BAO up to 24 hours from stroke symptoms compared to MM. The treatment effect in BAO patients with NIHSS <10 was less certain. Further studies are of interest to evaluate the efficacy of EVT in basilar occlusion patients with milder symptoms.

AIM: To investigate the clinical features of acute exacerbation chronic obstructive pulmonary disease (AECOPD) of complicated with type 2 diabetes mellitus (T2DM), and analyze the related clinical features and risk factors. METHODS: This was a single-center cross-sectional study. From March 2020 to January 2023, 479 hospitalized patients with AECOPD in the department of respiratory and critical care medicine, Suining Central Hospital were included. There were 215 patients in AECOPD group and 60 patients in AECOPD with T2DM group. The collected variables included demographic data, complications, blood routine, infection index, random blood glucose, blood gas analysis and lung function. The adoption rate and constituent ratio of the basic description classification data were expressed as mean standard deviation for the normal distribution measurement data and median interquartile range for the skew distribution measurement data. T-test was used for normal distribution and non - parameter test was used for non-normal distribution. The categorical variables were tested by chi-square test. Rank sum test was used for rank variable data. Binary logistic regression model was used to investigate the independent factors associated with T2DM in patients with AECOPD. Finally, the results of logistic regression were verified and visualized by nomogram, validation curve, ROC curve and DCA curve. P<0.05 was a significant statistical difference. RESULTS: Univariate analysis showed that there were significant differences in body mass index (BMI), essential hypertension, coronary heart disease, atrial fibrillation (AF), pulmonary function (GOLD stage), blood neutrophil (NS), blood lymphocyte (LYM), arterial blood gas PaCO2, Alanine transaminase (ALT) and random blood glucose (RBG) between the two groups (P<0.05). The binary logistic regression model (C-index=0.847) was constructed with the above 10 variables, the results showed that BMI (OR=1.309), Af (OR= 8.188), LYM counts (OR=0.474), PaCO2 (OR=1.082) and RBG (OR=1.434) were independently associated with type 2 diabetes in patients with AECOPD (all P>0.05). The results of logistic regression were verified and visualized by Nomogram and its-associated ccurves. The MAE and AUC curves were 0.021 and 0.847 respectively, indicating that the model had good prediction consistency and accuracy. The DCA curve showed that Nomogram's risk threshold ranged from 0.01 to 0.99, suggesting that nomogram's model had better clinical predictive value. CONCLUSION: Our results showed that increased BMI, PaCO2 and random glucose, decreased blood lymphocyte, and atrial fibrillation is an independent clinical feature of AECOPD with T2DM. These results suggest that the immune function of patients with AECOPD and T2DM are more severely impaired and more likely to be accompanied by atrial fibrillation, which is a potential cause of poor prognosis in these patients. Meanwhile, this conclusion needs to be further verified in multicenter study with large sample size.

The condition of patients with severe traumatic brain injury (sTBI) complicated by corona virus 2019 disease (COVID-19) is complex. sTBI can significantly increase the probability of COVID-19 developing into severe or critical stage, while COVID-19 can also increase the surgical risk of sTBI and the severity of postoperative lung lesions. There are many contradictions in the treatment process, which brings difficulties to the clinical treatment of such patients. Up to now, there are few clinical studies and therapeutic norms relevant to sTBI complicated by COVID-19. In order to standardize the clinical treatment of such patients, Critical Care Medicine Branch of China International Exchange and Promotive Association for Medical and Healthcare and Editorial Board of Chinese Journal of Trauma organized relevant experts to formulate the Chinese expert consensus on clinical treatment of adult patients with severe traumatic brain injury complicated by corona virus infection 2019 ( version 2023) based on the joint prevention and control mechanism scheme of the State Council and domestic and foreign literatures on sTBI and COVID-19 in the past 3 years of the international epidemic. Fifteen recommendations focused on emergency treatment, emergency surgery and comprehensive management were put forward to provide a guidance for the diagnosis and treatment of sTBI complicated by COVID-19.

OBJECTIVE To investigate the effect and mechanism of Poria cocos polysaccharides on the regulation of blood glucose in type 2 diabetes mellitus （T2DM）model rats by phosphatidylinositol 3-kinase（PI3K）/protein kinase B （Akt）/forked box transcription factor O 1（FoxO1）pathway. METHODS SD rats were randomly divided into blank control group （no modeling ，no administration），model group （modeling，no administration ），metformin group （modeling，200 mg/kg）and P. cocos polysaccharide low-dose，medium-dose and high-dose groups （modeling，100，200，400 mg/kg），8 in each group. Except for blank control group ， other groups were given high fat diet combined with streptozotocin to construct the model of T 2DM rats. At the same time ， administration groups were given relevant dose of medicine intragastrically ，and blank control group and model group were given constant volume of water intragastrically ，once a day ，for consecutive 42 days. During the experiment ，general condition and bodyweight of rats were observed every day ；fasting blood glucose （FBG）of rats were collected ，and oral glucose tolerance test were conducted and area under curve （AUC）was calculated the day before last administration. After last medication ，the heart ，liver， kidney organ index were calculated ；the levels of HbA 1c，TC，TG，MDA，SOD，GSH-Px and hepatic glycogen content were detected. HE staining was used to observe the pathological changes of liver and pancreatic tissue ，and the pathological grade score was calculated. Western blot assay was used to detect the protein expressions of p-PI 3K，p-Akt，p-FoxO1， PEPCK and G 6Pase in liver tissues. RESULTS Compared with blank control group ，the rats of model group suffered cc1965@163.com from polydipsia ，polyphagia and polyuria ；the body weight ， the levels of SOD and GSH-Px ，the protein expressions of p-PI 3K，p-Akt and p-FoxO 1 were significantly decreased （P＜0.05）；liver and kidney organ index ，blood glucose level at 0，0.5 and 2 hours after intragastric administration of glucose solution ，AUC， FBG，HbA1c，serum levels of MDA ，TC，TG and hepatic glycogen content ，liver and pancreatic pathological grade score ，the protein expressions of PEPCK and G 6Pase were all increased significantly （P＜0.05）. Compared with model group ，the general condition of rats in P. cocos polysaccharide groups were all improved ，and all of above indicators had been reversed to varying degrees. CONCLUSIONS P. cocos polysaccharide can downregulate protein expressions of PEPCK and G 6Pase which are key enzymes of gluconeogenesis ，inhibit hepatic gluconeogenesis ，effectively decrease blood glucose levels and regulate glucolipid metabolism in T 2DM model rats by weakening oxidative stress and upregulating PI 3K/Akt/FoxO1 pathway.
