Objective In order to explore the application and effects of PBL in integrated nursing course for senior vocational nursing students. Methods Nursing students were randomly divided into the experimental group( 122 students) and the control group( 189 students). PBL was applied to the experimental group while traditional method was applied to the control group during the course. All the students fulfilled the Critical Thinking Disposition Inventory-Chinese Version (CTDI-CV) before and after the course. Theory and practical examinations were administrated after the course. Results The experimental group was better in theory and practical examinations than the control group. There were significant differences in total score and some subscale scores of CTDI-CV between the two groups after the course, and also between the beginning and the end of PBL for the experimental group. Conclusions The application of PBL in integrated nursing course can effectively promote the mastery of knowledge and skills, and can improve the critical thinking ability.

In recent years, the research hot in the field of solid tumor and blood tumor focuses on the myeloid-derived suppressor cells (MDSCs).In tumors, MDSCs not only exert immunosuppression by inhibiting T cell proliferation, destroying the functions of natural killer cells and recruiting regulatory T cells, but also play non-immunosuppression roles in the promotion of angiogenesis and tumor metastasis.All of these hinder the anti-tumor therapy, and particularly affect the curative effect, which are related with a poor clinical prognosis.MDSCs can be used as prognostic markers, which provide new targets for immunotherapy.

ObjectiveTo study the feasibility and technique in liver transplantation (LT) in an adult with situs inversus (SI) and reviewed the medical literature on this subject.MethodsA 45-year-old male with complete SI,suffered from progressive hepatic failure secondary to hepatolithiasis,obstructive jaundice,portal hypertension and liver cirrhosis.He underwent liver transplantation in July 2004.His anatomy was studied by preoperative CT scan and three-dimensional liver reconstruction imaging and angiography.LT was performed using the modified piggyback technique.The donor right liver was rotated 45 degree to the left,making the donor left liver pointing to the left paracolic sulcus and the donor right liver was in the recipient hepatic fossa.The donor suprahepatic vena cava was anastomosed end-to-side to the recipient vena cava,and the infrahepatic vena cava was closed by oversewing.ResultThe patient recovered uneventfully.His liver function was stable during a follow-up of 75 months.ConclusionLT in patients with SI is safe and feasible.Exact determination of the anatomy,comprehensive preoperative planning,and good technique in liver transplantation play important roles in LT for patients with SI.

Objective To study the effect of hyperbaric oxygen(HBO) treatment on plasma endotoxin,sCD14 and plasma endotoxin inactivation capacity(EIC) in acute necrotizing pancreatitis(ANP) in rats and its possible mechanism.Methods SD rats were randomly divided into control group,sham operation group,ANP group and ANP+HBO group.Rat ANP models were made by retrograde injection of 3.5% sodium(taurocholate)(2.5mL/kg) into the pancreatic duct.Thirty minues after models had been made,ANP+HBO group was treated by hyperbaric oxygen for 2h.At 3h,6h,and 10h after establishment of rat models,the plasma endotoxin,sCD14,EIC,TXB_2 and 6-K-PGF_(1a) leves were determined in each group.Results At 3h and 6 h after rat models were established,the levels of endotoxin,sCD14,and TXB_2 in ANP+HBO group were significantly lower than those in ANP group(P

Objective To investigate the method and effectiveness of the digital artery series and parallel of island flap for repairing degloved injuries of the fingertip of thumb or adjacent finger Methods Between September 2008 and July 2012,the finger artery series retrograde island flaps tiled in the repair of finger degloving injury in 13 cases,repair of adjacent finger tip degloving injury in 11 cases; 8 cases of degloved injuries of the fingertip were tiled with the digital artery parallel island flap from ulnaris middle finger and radialis ring finger of arteria digitalis communis pedicled which were from the same palm side.The size of skin and soft tissue defect ranged from 2.0 cm × 1.8 cm-7.2 cm ×5.5 cm,gutted flap minimum ranged from 1.1 cm × 1.0cm-1.5 cm × 1.3cm,and the maximum ranged from 3.0 cm × 2.2 cm-5.5 cm × 4.5 cm.The donor sites were repaired with the intermediate split thickness free skin grafts and performed with pressure dressing.Results The group of 32 cases,in 1 case the flap vasospasm occurred in operation of free process,the symptoms disappeared after local application of papaverine and hot compress ; 1 case of flap occurred disturbance of blood circulation after operation because of tight suturing for pedicle,the symptoms relieved after removing the stitches at intervals; 2 cases blisters appeared after operation,disappeared after a week.All skin flaps were survived,incision and skin graft donor sites healed by first intention.Twenty patients were followed-up from 6 to 12 months after operation.All flaps presented the satisfactory appearance and texture,recovered protective feeling.At last follow-up,the two-point discrimination was 7 to 10mm,and the flexion and extension function of wounded fingers recovered to normal.According to the functional assessment criteria of upper limb formulated by the Hand Surgery Branch of Chinese Medical Association,there were excellent in 19 cases,good in 10 cases,and moderate in 3 cases.No significant loss to the donor shape and function.Conclusion The surgery by adopted the digital artery series or parallel of island flap for repairing degloved injuries of the fingertip of thumb or adjacent finger,not only has the advantages of simpleness,safety and reliability,but also can satisfy the patients who aren't willing to accept or because of physical reasons can't accept the treatment of abdominal skin tube or nail flap from hallux toe,which performs in both high-end and low level hospitals,and deserves of general application.

Objective To explore the theory of curriculum contents for gerontological nurse practitioner training which is suitable for the situation of our country. Method Delphi technique was used in this research to build content indicators of gerontological nurse practitioner training curricu-lum, and calculate the variation coefficient. Results The theory training curriculum includes founda-tions of gerontological nursing, geriatric syndrome, facilitating physiological balance and general gero-tological care modules and 41 core indexs. Every coefficient of variation is less than 20 percent [(4.35±0.71), (4.63±0.57), (4.55±0.57), (4.67±0.55)]. The mean values of the importance (4.54± 0.622) and general characteristics are more than four. Conclusion The content setting of the geron-tological nurse practitioner training theory course not only highlights the training characteristics of the geriatric care, but also has comprehensive and systematic content, reflects humanistic care spirit and pays attention to developing nurses’clinical practice ability. Therefore, it is worthy of reference and promotion.

Objective To investigate the application and evaluation of objective structured clinical examination( OSCE)in the Comprehensive Nursing Skills and Clinical Thinking Course. Methods We set OSCE assessment program in the Comprehensive Nursing Skills and Clinical Thinking Course,and applied to 214 high vocational nursing students to analyze their exam results,critical thinking ability and the evaluation of OSCE with the method of questionnaire. The differences were compared between the assessment results of OSCE and traditional single course. Results In each OSCE station,the nursing basic skills gained the tiptop score (92. 14 ± 6. 14),while case study gained the lowest score(72. 71 ± 10. 12). There were statistical significance in four OSCE stations performances(F = 261. 171,P < 0. 05). Critical thinking ability score was(263. 85 ± 22. 71),which did not reached positive. The satisfaction score of students to OSEC evaluation method was 88. 26% higher than 85. 45% of traditional one(t = - 3. 995,P < 0. 05). Conclusions OSCE can objectively reflect the weak aspect of students clinical competence,and the students perform it high acceptation. It can provide an evidence for the further improvement of high vocational education.

Objective To evaluate the correlation between microvascular invasion(MVI) and prognosis in patients with hepatocellular carcinoma (HCC),and to analyse the influencing factors of MVI in patients with HCC.Methods Total of 81 patients with hepatocellular carcinoma treated in Beijing Hospital from January 2014 to December 2016 were retrospectively studied.There were 65 males and 16 females.The mean age was 59.6± 12.7 years,and the age ranged from 21 to 87 years old.Pathological examination showed presence of MVI in 35 patients.Results Total of seventy-six patients with hepatocellular carcinoma were followed-up.The 1-,2-,3-and 4-year overall survival rates in the 35 patients with microvascular invasion of hepatocellular carcinoma were 78.6％,55.4％,38.3％,and 32.2％,respectively.The 1-,2-,3-,and 4-year overall survival rates of the 41 patients without microvascular invasion were 93.4％,76.5％,68.2％ and 68.2％,respectively.The difference was significant (P＜0.05).Cox multivariate regression analysis showed that microvascular invasion was an independent risk factor of overall survival after surgery (HR=3.071,95％ CI:1.239～7.610,P＜0.05).Sub-group analysis was done on patients with microvascular invasion based on pathological results which included the number of MVI lesions,the call number in the MVI lesion,the distance of the MVI to the primary liver cancer,and the gradings of MVI.There were no significant differences in the overall survival outcomes (P＞0.05).Multivariate logistic regression analysis showed the maximum diameter of tumor ＞ 5 cm (OR =6.340,95％ CI:2.000 ～ 20.096),preoperative total bilirubin (TBil) ＞ 17 μmol/L (OR =5.067,95％CI:1.386 ～ 18.525),and preoperative alpha-fetoprotein (AFP) ＞400 μg/L (OR =6.042,95％ CI:1.435 ～ 25.444) were independent risk factors of microvascular invasion (P＜ 0.05).Conclusion Hepatocellular carcinoma patients with microvascular invasion had poor prognosis.Preoperative AFP,preoperative TBil,and diameter of tumor were independent risk factors of microvascular invasion in patients with hepatocellular carcinoma.

Objective:To understand the prevention knowledge of brucellosis among permanent residents in the agricultural area of Hulunbuir City, Inner Mongolia Autonomous Region, and to provide a scientific basis for formulating brucellosis prevention strategies and measures.Methods:From May to December 2018, Daur Autonomous Banner of Morin Dawa and Arun Banner in the agricultural area of Hulunbuir City were selected as the survey sites. Three townships were selected from each banner, and one administrative village from each township was selected as the survey village. The permanent residents aged ≥14 who had lived in the survey village for at least one year were selected as the survey subjects. Serum was separated by the examiner and the rose-bengal plate agglutination test (RBPT) was conducted. The positive sera were further tested by tube agglutination test (SAT).Questionnaires were conducted by investigators in the form of face-to-face case interview, including general demographic information, family information, brucellosis prevention knowledge awareness status, epidemiological contact history, prevention status, general behavior, etc., to calculate the awareness rate of brucellosis prevention knowledge.Results:A total of 880 sera were isolated, of which 185 were positive for RBPT. Further examination of SAT showed that the positive rate of SAT was 17.27% (152/880). The overall awareness rate of brucellosis prevention knowledge was 46.73% (16 450/35 200). The awareness rates of males and females were 47.82% (8 473/17 720) and 45.64% (7 977/17 480), respectively. The 21 - 40 years old group had the highest awareness rate [60.94% (3 705/6 080)]. The awareness rates of primary school and below, junior high school, senior high school and above were 45.96% (11 969/26 040), 48.79% (3 962/8 120) and 49.90% (519/1 040), respectively. The awareness rate of people with livestock raising behavior in the year before the survey was 47.35% (8 011/16 920), while the awareness rate of people without such behavior was 46.17% (8 439/18 280).Conclusions:The overall awareness rate of brucellosis prevention knowledge among permanent residents in the agricultural area of Hulunbuir City is low. It is necessary to strengthen the training of relevant knowledge and strengthen the publicity and education of people with low awareness rate.
