Objective To investigate the effect of targeted monitoring on the control of central venous catheter associated infection, study the difference of CVC?RI infection rate and the distribution of pathogenic bacteria in the general hospital and the maternal and child hospital, and analyse the main pathogenic bacteria drug resistance characteristics. Methods From January 2013 to December 2014,685 cases patients with central venous catheterization in the Port Hospital of Hebei Port Group Company Limited,and four cooperative hospitals ( Affiliated Hospital of North China University of Science and Technology, People′s Hospital of Tangshan, Tangshan Port Economic Development District Hospital, Maternal and Child Health Care Hospital of Laoting County) were selected as the research objects. The difference of infection rate before and after the targeted monitoring in 2014 was compared. The tip of the catheter and the peripheral blood were cultured in the patients with suspected infection,bacterial identification and drug sensitivity test were carried out using Compact VITEK2 automatic bacteria identification/drug sensitivity analyzer. Results The infection rate of CVC?RI of five hospitals was 18. 75%( 60/320 ) in 2013, 11. 51%( 42/365 ) in 2014, the difference of infection rate was statistically significant before and after the implementation of the target monitoring(χ2=7. 059,P<0. 05) . The CVC?RI infection rate was 15. 52%(81/522) in the general hospital,12. 88%(21/163) in the maternal and child hospital,the difference was not statistically significant(P>0. 05). In 102 cases of CVC?RI,105 bacterial strains were detected in 91 cases,gram positive bacteria accounted for 51. 43%( 54/105) ,gram negative bacilli accounted for 40. 95%( 43/105) ,fungi accounted for 7. 62%( 8/105) . There was no significant difference in the proportion of pathogenic bacteria in the general hospital and the maternal and child hospital(P>0. 05). Grampositive cocci were mainly staphylococcus aureus and coagulase negative staphylococci,they were completelysensitive to linezolid, quinupristin/ dalfopristin, tigecycline, and vancomycin. They were high sensitivity torifampicin,while highly resistant to gentamicin, tetracycline, penicillin; Gram negative bacilli were mainlypseudomonas aeruginosa and escherichia coli,they were high sensitivity to meropenem,imipenem,while resistantto multiple antimicrobia1s. Conclusion Adhere to the implementation of targeted monitoring help to reduce theoccurrence of CVC?RI. The isolation of pathogenic bacteria from multiple drug resistance should be paid moreattention.

Objective To investigate the feasibility, rationality and efficacy of the autologous dermal-fat composite tissue used as filling materials in the repair of nasal dorsum collapse.Methods The dermal fat composite tissue block (7.0 cm× 1.0 cm × 1.0 cm) was removed from the buttocks or abdoman as filling materials. 13 cases of nasal dorsum and nasal-shaped misfits were treated by using an umbrella graft of the auricular cartilage plus dermal-fat composite tissue graft to reconstruct natual shape of nasal dorsum and tip. Results The nasal dorsum and tip were repaired in 13 patients with collapsed nasal dorsum. The dermal-fat composite tissue survived well, and the incisions were healed in stage Ⅰ and the incision trace was not obvious. After follow-up for one year, the shape of nose was much satisfactory. Conclusion It is a well-accepted and easy-going procedure to repair collapsed nasal dorsum with autologous dermal-fat or a combination of composite ear cartilage tissue graft, with satisfactory effect and no rejection reactions.

Oxidative stress is a redox imbalance in the body, which is one of the important factors leading to tissue damage and diseases. The nuclear factor E2-related factor 2 (Nrf2)-Kelch like ECH-associated protein 1 (Keap1) signaling pathway is not only an important defense system against oxidative damage, but also one of the key signaling pathways of the antioxidant capacity. Numerous studies have shown that targeting the Keap1-Nrf2 signaling pathway to activate Nrf2 has become an effective strategy for the treatment of oxidative stress and related diseases. Using small molecules to directly block the Keap1-Nrf2 protein-protein interaction (PPI) is one of the important directions for activating Nrf2 and exerting the cytoprotective effect, which can avoid the potential side effects of covalent modification of Nrf2. On the other hand, the Keap1 is an efficient E3 ubiquitin ligase that has been used in the design of proteolysis targeting chimeras (PROTACs). This review summarizes the research progresses of Keap1-Nrf2 protein interaction inhibitors and degraders based on the Keap1 E3 ubiquitination system in recent years.

Objective The 4-and 16-hydroxylated metabolites of estrogens have been implicated in carcinogenesis,whereas its 2-hydroxylated metabolites have been shown to have antiangiogenic effects.We aimed to examine whether the polymorphisms of catechol-O-methyltransferase(COMT)involved in the estrogen metabolism are associated with endometrial cancer risk.Methods Polymerase chain reaction- restrictive fragment length polymorphism(PCR-RFLP)analysis was used to study the variant allele frequency distributions of COMT Val158Met genetic polymorphism in a population based case-control study with 132 endometrial cancer cases and 110 controls.Odds ratios(OR)and 95% confidence intervals(CI) were estimated by unconditional logistic regression after adjustment for known or suspected risk factors for endometrial cancer.Results The most frequent genotype was COMT~(Val/Val)(47.2%,52/110)in control group and COMT~(Mal/Met)(58.3%,77/132)in endometrial cancer group.The difference between the two groups was of statistical significance(P

In the past few decades,Chinese government attempted to reduce the economic burden of chronic diseases and lower family fmancial risk of patients by establishing a nationwide coverage of Social Health Insurance system.However,the payment mode of Social Health Insurance varies across Chinese healthcare settings,and the effectiveness of each mode differs.This study aimed to evaluate the effects of integrated case payment on medical expenditure and readmission of inpatients with chronic obstructive pulmonary disease (COPD),a complex,multicomponent,chronic condition.A nonrandomized,comparative method was used in this study.Inpatients with COPD before (n=1569) and after the integrated case payment reform (n=4764) were selected from the inpatient information database of the New Cooperative Medical Scheme Agency of Xi County.The integrated case payment comprises the case payment (including price-cap case payment and fixed-reimbursement case payment) and clinical pathway (including clinical pathway A,clinical pathway B and clinical pathway C).Effects of integrated case payment were evaluated with indicators of per capita total medical expense and readmission within 30 days.A multivariate linear regression and a binary logistic regression were used to conduct statistical analysis.The results showed that case payment,comprising price-cap case payment (β=2382.988,P＜0.001) and fixed-reimbursement case payment (β=2613.564,P＜0.001),and clinical pathway C (β=1996.467,P＜0.001) were risk factors of per capita total medical expenses.Clinical pathway A (β=1443.409,P＜0.001) and clinical pathway B (β=-1583.791,P＜0.001) were protective factors.The interactive effects of case payment with hospital level (β=0.710,P＜0.001) lowered the readmission rate within 30 days.Meanwhile,clinical pathways A (β=18.949,P＜0.001),B (β=-19.752,P＜0.001) and C (β=-1.882,P＜0.1) were associated with the rate increase.The findings revealed that integrated case payment ensured the quality of care for inpatients with COPD to some extent.However,this payment mode increased the per capita total medical expense.Further,policy-makers should set reasonable reimbursement standards of case payment,unify the type of case payment,and strengthen the supervision of the reform to enhance its function on medical cost control.

Objective To observe the clinical efficacy of acupuncture plus hyperbaric oxygen in treating depression after cerebral stroke.Method A total of 120 patients with depression after cerebral stroke were randomized into a treatment group of 60 cases and a control group of 60 cases. The treatment group was intervened by acupuncture plus hyperbaric oxygen, while the control group was intervened by Fluoxetine. Before the treatment, and respectively after 14-d and 28-d treatments, the patients were evaluated by Hamilton Depression Scale (HAMD) and National Institute of Health Stroke Scale (NIHSS), and the therapeutic efficacies were compared between the two groups. Result The treatment group was significantly superior to the control group in comparing therapeutic efficacy (P<0.01). After 1 course of treatment, the HAMD and NIHSS scores dropped significantly in the treatment group (P<0.01); the scores in the control group showed a declining tendency but without statistical significances (P>0.05). After 2 treatment courses, the HAMD and NIHSS scores were significantly different from those before the treatment in both groups (P<0.01), and the differences were more significant in the treatment group (P<0.01).Conclusion Acupuncture plus hyperbaric oxygen is effective in treating depression after cerebral stroke, and it can obviously improve the neural function.

Objective To evaluate the application value of hyperinsulinemic euglycemic clamp in the diagnosis and treatment of newly-onset diabetic patients. Methods Totally 11 newly-onset diabetic inpatients (10 patients with type 2 diabetes mellitus and 1 patient with latent autoimmune diabetes of adulthood) who were diagnosed in the Department of Endocrinology of Peking Union Medical College Hospital from January 2009 to August 2009 were included in this study. Hyperinsulinemic euglycemic clamp was applied to measure the glucose disposal rate (M value). Afterwards insulin pump therapy was applied and the total insulin dosage per day to get to the target of the fasting and postprandial blood glucose was calculated. Final]y the relationships between insulin dosage per day and the M value, body mass index (BMI) , fasting blood glucose, fasting insulin level were separately analyzed. Results The insulin dosage was only negatively correlated with M value (r = - 0. 83, P = 0. 003), and was not significantly correlated with BMI (r = 0.54, P = 0.106), fasting blood glucose (r = - 0. 16, P =0. 657) , and fasting insulin (r = 0. 16, P = 0. 659). The formula of insulin dosage and M value according to the mathematic model as follows: insulin dosage per day = - 3. 327 M + 49. 849. Conclusion Hyperinsulinemic euglycemic clamp can effectively evaluate the insulin sensitivity in the newly-onset type 2 diabetic patients, and thus can be a useful tool in deciding the clinical insulin dosage.
