To evaluate the charasteristics and risk factors of hospital infections in patients with contagious diseases, 489 patients with contagious diseases were analyzed. Among 18 patients who contracted hospital infections, 17 were suffering from chronic hepatitis. 77 78% of them were over 40 years old. Infection of ascitic fluid, lower respiratory tract, and blood stream comprised 77 78% of the infections. Most of the doctors used antibiotics empirically. The survey showed that patients over 40 years old in an infectious diseases hospital were vulnerable to hospital infections. Hospital infection often occurred in the abdomen, lower respiratory tract, and blood stream. Abdominal paracentesis liver puncture biopsy, and lumbar puncture were the first three exogenous risk factors.

OBJECTIVE To discuss management in the prevention and treatment of infectious diseases and influenza A(H1N1) the according to law.METHODS The requirements of prevention and treatment for infectious diseases and influenza A(H1N1),were set out according to "Communicable Disease Prevention Act" and other relevant laws and regulations.RESULTS The prevention and control strategies and measures of influenza A(H1N1) still existed some problems.CONCLUSIONS The key doing a good job of prevention and control for infectious diseases and influenza A(H1N1) is according to the law scientificly and orderly.

The epidemic situation of influenza A(H1N1) throughout the world had evoked close attention of the World Health Organization(WHO).WHO director-general pointed out that the pandemic alert level had been set at 3,which was then raised by WHO from 3 to 4 and from 4 to 5 two days later.The present paper focused on the finding of influenza virus,the influenza prevalence in history,and introduced the scientific countermeasures for influenza A(H1N1),including the spreading of influenza virus,the clinical features,treatment,main measures of prevention and control,etc.

Objective To investigate the effects of omega-3 polyunsaturated fatty acids (ω-3 PUFA) on inflammatory response,nerve damage,and outcomes in patients with severe traumatic brain injury (sTBI).Methods Altogether 120 sTBI patients were selected from January 2013 to September 2014 in Jinjiang Hospital of Traditional Chinese Medicine and divided with a random number table into experimental group (with ω-3 PUFA supplementation,n =60) and control group (without ω-3 PUFA supplementation,n =60).Sixty blood samples from healthy people visiting the physical examination clinic were collected as normal controls.The serum levels of tumor necrosis factor-α (TNF-α),interleukin (IL)-1,IL-6,S100B and neuron-specific enolase (NSE) were detected with enzyme-linked immunosorbent assay (ELISA).Glasgow Coma Scale (GCS) score,Acute Physiology and Chronic Health Evaluation (APACHE) Ⅱ score and outcomes of the two groups were compared.Results The serum levels ofTNF-α,IL-1,IL-6,S100B,and NSE protein significantly increased in patients with sTBI compared with the normal controls (all P ＜ 0.05).Compared with the control group,the serum levels of inflammatory related factors (TNF-α,IL-1,IL-6) in the experimental group were significantly decreased on the 3rd day [(213.81 ±29.33) μg/L vs.(267.76 ±31.35) μg/L,(121.81 ± 10.63) μg/L vs.(152.60 ± 11.45) μg/L,(81.89 ± 8.34) μg/L vs.(106.62 ± 10.35) μg/L,all P ＜ 0.05],S100B and NSE protein expressions were significantly decreased on the 7th day [(1.32 ± 0.09) μg/L vs.(1.67 ± 0.12) μg/L,(12.57 ± 1.53) μg/L vs.(17.57 ±2.30) μg/L,both P ＜0.05].Compresd with the control group,the experimental group showed significantly higher GCS scores (9.32 ± 1.64 vs.7.14 ± 1.30,P =0.02) and significantly lower APACHE Ⅱ scores (14.37 ± 2.27 vs.17.00 ± 1.85,P =0.04) on the 14th day.Compresd with the control group,the experimental group showed lower mortality during the follow-up [11.7％ (7/60) vs.15.0％ (9/60)],but with no significant differences (P =0.49).Conclusion Supplementation of ω-3 PUFA could exert neuroprotective effect by effectively regulating inflammatory response and reducing the damages to glia and neurons in patients with sTBI,which is a promising agent for clinical application.

Antibody-drug conjugates(ADCs)are a new type of targeting antibodies that conjugate with highly toxic anticancer drugs via chemical linkers to exert high specificity and efficient killing of tumor cells,thereby attracting considerable attention in precise oncology therapy.Cetuximab(Cet)is a typical antibody that offers the benefits of good targeting and safety for individuals with advanced and inoperable cutaneous squamous cell carcinoma(cSCC);however,its anti-tumor activity is limited to a single use.Cisplatin(CisPt)shows good curative effects;however,its adverse effects and non-tumor-targeting ability are major drawbacks.In this study,we designed and developed a new ADC based on a new cytotoxic platinum(Ⅳ)prodrug(C8Pt(Ⅳ))and Cet.The so-called antibody-platinum(Ⅳ)prodrugs conjugates,named Cet-C8Pt(Ⅳ),showed excellent tumor targeting in cSCC.Specifically,it accurately delivered C8Pt(Ⅳ)into tumor cells to exert the combined anti-tumor effect of Cet and CisPt.Herein,metabolomic analysis showed that Cet-C8Pt(Ⅳ)promoted cellular apoptosis and increased DNA damage in cSCC cells by affecting the vitamin B6 metabolic pathway in tumor cells,thereby further enhancing the tumor-killing ability and providing a new strategy for clinical cancer treatment using antibody-platinum(Ⅳ)prodrugs conjugates.

Objective: To investigate the clinical research of Guo's Liulian therapy in treating acute pancreatitis intestinal mucosal barrier dysfunction and provide reference for the patients with acute pancreatitis. Methods: The 68 patients with acute pancreatitis who were admitted to our hospital from September 2016 to May 2018 were selected as study subjects. According to the random number table method, the patients were divided into the observation group and the control group, with 34 cases in each group. The patients in the control group were treated with conventional western medicine. The patients in the observation group were treated with Guo's Liulian therapy on the basis of the above treatment. The time of intestinal paralysis was compared between the two groups. The changes of intestinal mucosal barrier function and serum inflammatory factor related indexes before and after treatment were analyzed in the two groups. The difference of therapeutic effects between the two groups was observed. Results: In the observation group, the abdominal pain relief time, abdominal distention relief time, bowel sound recovery time, and first bowel anus defecation time were significantly lower than those in the control group (t=7.621, 5.332 6.625, 8.762, all Ps<0.01). After treatment, serum LPS, DAO, ET, D-lactic acid, TNF-α, IL-1, IL-6, IL-8, and IL-10 and urine L/M were significantly lower in the observation group, while the serum ITF and MFG-E8 were significantly higher in the observation group (t=9.856, 6.974, 9.784, 16.068, 9.550, 12.506, 22.343, 16.625, 6.774, 23.469, 20.118, 23.031, all Ps<0.01). Conclusions The Guo's Liulian therapy treatment of acute pancreatitis in patients with intestinal mucosal barrier dysfunction can reduce the palsy remission time, reduce inflammation, increase serum ITF, MFG-E8 levels, repair of intestinal permeability, and improve the intestinal barrier function.

Objective:To investigate the status quo of knowledge, attitude and practice of enterostomal therapists (ET) in chronic wound pain management and analyze its influencing factors, so as to provide references and suggestions for continuous improvement of wound pain management.Methods:The convenient sampling method was used to investigate 260 ET objects. The survey tools were a self-designed General Information Questionnaire and questionnaires on knowledge, attitude and practice of ET on chronic wound pain.Results:A total of 260 questionnaires were distributed and 238 were valid. The score of ET on chronic wound pain knowledge questionnaire was (5.90±1.49) , the score of ET on chronic wound pain attitude questionnaire was (25.74±3.57) and the score of ET on chronic wound pain management practice questionnaire was (53.28±12.52) . The results of multiple linear regression showed that professional title, working years in wound care and working experience in relevant departments of oncology were the influencing factors of knowledge, attitude and practice of ET in chronic wound pain management ( P<0.05) . Conclusions:ET lacks knowledge of chronic wound pain and has acceptable attitudes, and his practical behaviors need to be strengthened urgently.Hospital administrators vigorously develop full-time ET and implement multidisciplinary collaboration to manage wound pain. When selecting ET training personnel, it is recommended that nurses at or above the intermediate level be the target of training. For ET, it is necessary to continuously improve professional titles and re-learn, and continuously accumulate experience in practice. For ET schools, a wound pain training knowledge system based on job competence should be established, and corresponding training should be carried out for wound specialist nurses.
