Objective To explore the relationship between the levels of plasminogen activator inhibitor-1(PAI-1) and type 2 diabetes mellitus (T2DM) with vascular complication. Methods The plasma concentrations of PAI-1 were determined by ELISA in 34 control subjects (Control group) and 134 diabetic patients (T2DM group),which were further subdivided into 4 subgroups based on body mass index (BMI) and with or without macro-vascular complication. Results The PAI-1 levels in four diabetic subgroups were significantly increased compared with those of the control. The PAI-1 level in T2DM with macroangiopathy was significantly higher than that in T2DM patients without macroangiopathy (P

Objective:To determine the basic characteristics and clinical manifestations of hospitalized patients with psoriasis in Hunan, and to provide reasonable reference for the etiology and treatment of psoriasis.
Methods:Totally 190 patients with psoriasis from January 1, 2012 to December 31, 2012 treated in the Department of Dermatology, the Second Affiliated Hospital of Central South University were retrospectively analyzed. The data were analyzed by SPSS17.0.
Results:The ratio of male to female inpatient numbers was 3.13:1, aged was between 40 and 70 years. The most common subtype of psoriasis was psoriasis vulgaris (64.73%), followed by psoriatic erythroderma (18.42%). The distribution of the subtype of psoriasis did not differ by gender. Nineteen patients recalled clearly the cause of proriasis, 5 of which were caused by medicine, and 4 by drinking. Totally 96 cases accompanied with other diseases, 24.21%of which accompanied with cardiovascular system disease.
Conclusion:There is no season difference in the hospitalization of patients with psoriasis. there are more male than female inpatients. Treatment of psoriasis should consider clinical classification, drug adverse reactions, and individual factors for individual treatment.

Objective To evaluate the effects of the laryngeal mask airway for spontaneous breath-ing in short pediatric operation under Sevoflurane inhalation anesthesia.Methods Eighty children undergo-ing hernia surgery, of whom ASA Ⅰ or Ⅱ, in accordance with the random number table, were randomly divided into two groups( each 40 cases):the laryngeal mask airway for spontaneous breathing with Sevoflu-rane inhalation anesthesia in group A,and tracheal intubation for controlled ventilation with Sevoflurane inha-lationa nesthesia in group B.Children in the two groups were fasting for 6 hours and without drinking for 4 hours before anesthse ia.Anestheis a was induced with Sevoflurane inhalation fro all patients.The laryngela mask airway was insertde soon afet r induction of anesthesia with Sevoflurane inhalation,and anse thesia main-tained with Sevoflurane in halta ion in gor up A.P atients in gruo p B wereg iven cisatracurium 0.15 mg/kg intravenous injectio n before tracheal intubation, and anesthesia maintained with Sevoflurane inhalation, 40 minutes before the end of the surgeryt o sot p using muscle relaxant.Ten minutes before the end of the operation to stop Sevoflurane inhalation,in two groups.The end-tidal carbon dioxide partial pressure(PETCO2 ), mean blood pressure,heart rate,respiratory rate,pulse oxygen saturation and end-tidal sevoflurane partial pres-sure(PETSev) were recorded one minute before the induction of anesthesia,15 min,30 min,45 min,and 60 min after the induction of anesthesia.Both the time to regain consciousness and the time to remove laryngeal mask airway or tracheal catheter were recorded in two groups.Results The mean blood pressure, heart rate decreased in two groups after the induction of anesthesia(P<0.05).The value of PaCO2 increased and that of base excess decreased in 30 min after the induction of anesthesia in group A(P<0.05).The value of PETCO2 increased, and that of pH decreased in 45 min after the induction of anesthesia in group A (P<0.05).The movements of the limbs and head induced by operative stimulation in group A were more than those in group B(P<0.05),but the incidences of cough and laryngospasm induced by removing the laryngeal mask airw ay or tracheal catheter in group B were higher than those in group A(P<0.05).Both the time to regain consciousness and the time to remove laryngeal mask airway or tracheal catheter were shorter in group A than those in group B ( P<0.05 ) .Conclusion It is safe that the laryngeal mask airway for spontaneous breathing with Sevoflurane inhalation anesthesia in short pediatric operation.The time of anesthe-sia is beyond half an hour during operation and the artificial respiration sholu d be implemented.

Background: Tumor markers are widely used in clinical practice and have become important indicators in assessing cancer progress. There is increasing concern that chemotherapy combined with traditional Chinese medicine has effects in decreasing the level of tumor markers. Objective: To investigate the effects of chemotherapy combined with Kangliu Zengxiao Decoction (KLZX), a compound Chinese herbal drug, on tumor markers carbohydrate antigen 50 (CA 50), cytokeratin 19 fragment (CYFRA21-1) and carcinoembryonic antigen (CEA) in patients with advanced non-small-cell lung cancer (NSCLC) and to explore the relationships between clinical efficacy and tumor markers. Design, setting, participants and interventions: Patients were included from Punan Hospital of Shanghai Pudong New District and Longhua Hospital between October 2008 and December 2009. Seventy-four subjects with advanced NSCLC were randomly assigned into treatment group (n=37) and control group (n=37). Patients in the control group were treated with chemotherapy alone while patients in the treatment group were treated with chemotherapy combined with KLZX. Chemotherapy of NP (vinorelbine + cisplatin) was given for two cycles and patients in the treatment group were administered with KLZX during chemotherapy. Main outcome measures: Levels of CA50, CYFRA21-1 and CEA before and after treatment were evaluated and the relationship between changes in levels of tumor makers and tumor size, clinical symptoms and living condition score (Karnofsky score) was analyzed. Results: No patients achieved a complete remission. The disease control rates (complete remission (CR)+partial remission (PR)+no change (NC)) were 89.20% (33/37) and 70.30% (26/37) in the treatment and control group respectively (P<0.05). The levels of CA50, CYFRA21-1 and CEA were clearly decreased in the treatment group after treatment (P<0.05) while also decreased in the patients without progression of disease. There were no obvious changes of CA50, CYFRA21-1 and CEA in the control group, and there was even a trend of increase. Furthermore, the improvement rates of clinical syndrome were 51% (19/37) vs 11% (4/37) (P<0.05) in the treatment group and control group respectively. The total response rates of quality of life were 91.89% (34/37) vs 56.76% (21/37) (P<0.01) in the treatment and control group respectively. Conclusion: Combined chemotherapy with KLZX in treating advanced NSCLC can acquire better stabilizing tumor foci, decrease levels of tumor markers and improve the clinical symptoms and Karnofsky score.

Objective To examine the possible factors affecting the attainment of target serum trough concentration of vancomycin in premature newborns for optimization of clinical dosing regimens.Methods The vancomycin trough concentration data were collected retrospectively from preterm newborns who received intravenous infusion of vancomycin from December 2016 to March 2021.According to the Evidence-based Guideline for Therapeutic Drug Monitoring of Vancomycin:2020 Update by the Division of Therapeutic Drug Monitoring,Chinese Pharmacological Society,the patients were assigned to failure(＜5 mg/L)or success(5-15 mg/L)in target attainment,or beyond target group(＞15 mg/L)base on vancomycin trough concentration.Statistical software SPSS was used to analyze differences in clinical characteristics between different groups,and profile various factors that may affect attainment of target serum trough concentration of vancomycin.Results The median(interquartile range)trough concentration of vancomycin was 12.50(7.95-18.05)mg/L in 82 preterm newborns.The target trough concentration of vancomycin was attained in 47 preterm newborns(57.32％),and the corresponding trough concentration of vancomycin was 10.90(7.80-13.30)mg/L.The trough concentration of vancomycin was beyond target in 27 preterm newborns(32.93％).The corresponding median trough concentration of vancomycin was 21.80(18.00-23.80)mg/L.Serum trough concentration of vancomycin failed to achieve the target in only 8 preterm newborns(9.75％).The corresponding median trough concentration was 4.10(2.48-4.60)mg/L.Univariate analysis showed that there were statistically significant differences(P＜0.05)in postmenstrual age and current weight between the patients succeeded in attaining target trough concentration and those who failed to attain the target.Baseline serum creatinine and dosing interval showed statistically significant differences(P＜0.01)between the newborns who attained the target concentration and those with higher trough concentration beyond the target.Multivariate regression analysis showed that baseline serum creatinine(OR=1.063,95％CI 1.024-1.102,P=0.001,cutoff:62 pmol/L)and dosing interval(OR=6.693,95％CI 1.604-27.920,P=0.009)were independent risk factors for excessively high vancomycin trough concentrations.Conclusions The dosing regimens as recommended in the current package insert only enable the attainment of target serum trough concentration of vancomycin in half of the premature newborns.The dosing regimen of vancomycin should be optimized by taking postmenstrual age,current weight,baseline serum creatinine and dosing interval into account.Therapeutic drug monitoring is necessary to ensure safety and effectiveness.
