Objective: To explore the application of grid health education model in improving college students health literacy. Methods: The clustered stratified random sampling method was used among the pre-formative education freshmen in a Xi-an university, with 1 123 students randomly selected totally. The intervention group (578) received health literacy education based on grid health education model, while the control group (545) receuved the original health education model. The effect of gird model of health education on health literacy was compared between two groups of college students after one-semester intervention. Results: Insufficient health literacy was found among freshmen participants in Xi an(17.12%, 17.61%); health literacy on prevention and treatment of chronic diseases (15.92%, 16.70%) was significantly lower than the national average level of urban residents(22.73%). Health literacy of the two groups of college students was significantly improved(47.75%, 27.71%, χ 2=20.50, 5.47, P<0.05). The grid health education model had significant effects in improving health literacy among college students, except for health literacy on safety and emergency(P<0.05). Conclusion Health literacy of college students is insufficient compared to that of urban residents in China. Grid model of health education model is superior to conventional health education model, which is in line with the requirements of health education in colleges in the new era.

Objective:To improve the standardized training effects of the first year graduate new nurses by the mini clinical evaluation exercise (Mini-CEX) .Methods:By cluster sampling, a total of 91 new nurses hired in 2017 of Xinqiao Hospital Affiliated to Army Medical University were in control group; and 120 new nurses hired in 2018 were in experimental group. Control group carried out routine training method. On the basis of that, experimental group implemented the Mini-CEX based clinical nursing core competence training and operational skill training once a month after changing routine teaching rounds and operational training, lasting 12 times. The scores of Mini-CEX for the first and twelfth time of experimental group were compared by paired sample t-test, the theoretical achievements and skill performances of new nurses between two groups were compared by independent sample t-test. Results:The scores of Mini-CEX of clinical nursing core competence training and operational skill training in experimental group for the twelfth time were (6.27±0.46) and (6.73±1.10) respectively, higher than those for the first time with statistical differences ( t=-8.48, -7.64; P<0.01) . Among new nurses in standardized training of the first year, the theoretical achievements and skill performances of department in experimental group were (87.70±11.32) and (92.90±8.22) , those of hospital were (85.50±11.83) and (89.67±8.99) respectively, higher than those in control group with statistical differences ( t=-2.71, -2.09, -2.24, -3.22; P<0.05) . Conclusions:Mini-CEX has significant effects in training for the first year among new nurses .

Objective: To evaluate combined robotic and endoscopic surgery in the third space for gastric submucosal tumors(SMTs). Methods: Combined surgery in 4 patients were compared with 19 patients who underwent laparoscopic wedge resection between Aug 2017 and Feb 2018. Results: R₀ resection was achieved in all combined surgery patients. The operation time was longer (112±29 )min vs. (93±11 ) min (t=2.338, P<0.05), but less blood loss, (11±6)ml vs.(59±6)ml (t=15.102, P<0.01). In combined surgery group, there was a larger tumor over resected tissue percentage, 65.4%±28.2% vs.22.8%±19.6% ( t=3.680, P<0.05). Combined surgery group patients were with earlier first breaking wind (3±1.4) d vs.(4.1±0.9) d (t=2.026, P>0.05), and shorter hospital stay (6.5±1.3) d vs.( 8.5±0.6) d (t=4.902, P<0.01), but a little higher hospitalization costs(57 651±10 097)rmb vs.(42 620±5 086)rmb (t=4.508, P<0.01). There were no major postoperative complications occurred in neither groups, nor tumor recurrences after 3-month follow-up. Conclusion Combined robotic and endoscopic surgery in the third space for submucosal gastric tumors is a novel operation with short operation time, less blood loss and good result.

OBJECTIVETo evaluate the efficacy of hepatitis B viruse (HBV) vaccination and its influencing factors among children in rural area of Jiangsu province.

METHODSTwenty-five hundred and twenty-two children born after 1998 in rural area were selected as the study population using multistage cluster sampling method. HBsAg and anti-HBs were detected by enzyme linked immunoassay (ELISA) and radio-immunoassay (RIA), respectively. Anti-HBs negative children were boosted using different hepatitis B vaccines and the efficacy was compared. Factors causing HBV infection in HBsAg positive children were also investigated.

RESULTSHBsAg positive rates in 1-7 year olds were 0.28%-1.28%, and the anti-HBs positive rates decreased from 76.7% to 45.5%. The HBsAg positive rate in children not timely vaccinated was significantly higher than those with HBV vaccine injection within 24 hours after birth (1.4% vs. 0.5%, P = 0.031). More than 90% of the anti-HBs negative children had protective level of anti-HBs after boosted with HBV vaccine.

CONCLUSIONHBsAg positive rate in children born after 1998 in rural area of Jiangsu province decreased significantly, with an average of 0.8%. The reason for HBsAg carriage in children might be attributed to mother-to-infant transmission or not timely HBV vaccination.

Currently, pediatric emergency medicine (PEM) as practiced in many developed countries is different from ours in China. Chinese pediatric emergency medicine is just children's internal medicine and does not include general surgery, ear-nose-throat, etc. If children have an emergency condition that require specialized treatments they need to go to different departments. However in Canada, the pediatric emergency physicians will first treat the patients whatever the condition, then, if it is a complicated sub specialty problem, they will consult the specialist or let the patient see the specialist later. In addition, resuscitation is done in the pediatric intensive care unit (PICU) in China, but it is done in the emergency room in Canada. This article compares the differences in the pediatric emergency systems in Canada and China and also introduces the international standard system of pediatric triage.

OBJECTIVETo investigate the expression of VEGF-C and VEGF-D and their correlations with lymphangiogenesis and angiogenesis in gallbladder carcinoma.

METHODSFifty cases of gallbladder carcinoma with complete clinical and pathological data were analyzed. The expression of VEGF-C and -D, D2-40, CD31 was assayed by immunohistochemical staining, with 10 samples of normal gallbladder tissues away from cancer and 19 samples of chronic cholecystitis as controls, and their correlation with clinicopathological findings were analyzed retrospectively.

RESULTSThirty-two (64.0%) of the 50 gallbladder cancers were positive for VEGF-C protein expression by immunohistochemistry and the positive rate of VEGF-D protein expression was 62.0% (31/50). The protein expression of VEGF-C and VEGF-D in tumor tissues was significantly higher than that in normal gallbladder tissues away from the tumor (P < 0.05), but no correlation with that in chronic cholecystitis (P < 0.05). The VEGF-C expression correlated with the patient age and lymph node metastasis (both P < 0.05). The VEGF-D expression only correlated with lymph node metastasis (P < 0.05). In the 50 gallbladder cancers, the MLVD was 6.9 + or - 3.6 and the MVD was 36.1 + or - 12.8. The MLVD in both VEGF-C and -D positive groups was significantly higher than that in the negative groups (P = 0.000), and the lymph node metastasis also increased. MVD in both VEGF-C and -D positive groups was higher than that in the negative groups (P < 0.05), and it was also correlated with tumor differentiation (P < 0.05). A significant positive correlation was also found between VEGF-C and VEGF-D expression (r = 0.498, P < 0.01).

CONCLUSIONVEGF-C and VEGF-D are involved in the lymphangiogenesis and angiogenesis in gallbladder carcinoma, promote lymph node metastasis of the tumor, and both are important in the regulation of lymphangiogenesis and angiogenesis in this cancer. VEGF-C and VEGF-D are of clinical significance in evaluating lymph node metastatic potency and estimation of prognosis in gallbladder carcinoma.
