Objective To investigate the level of professional commitment of nursing baccalaureate students,and explore the relationship between the professional commitment and communication ability.Methods Questionnaires were used to investigate 430 nursing baccalaureate students who were studying in the school.Results The professional commitment of nursing students was in the middle level.Correlation analysis revealed that the communication ability was correlated with the professional commitment.Conclusions We should take measures to improve the competency of professional commitment of nursing undergraduate students,strengthen their communication ability,promote the construction of nursing staff.

Objective To know the influence of preoperative respiratory function exercise on the postoperative pulmonary function among patients with lung cancer. Methods Divided 80 patients with lung cancer into the observation group and the control group, there were 40 cases in the each group. Routine perioperative nursing cares was used in the control group, while a two weeks respiratory function exercise was used in the observation group. Compared the incidence rate of complications be-tween the two groups after the intervention, some indexes which can indicate the respiratory function were compared before and after the exercise in the observation group. Results The indexes such as PaO_2, SpO_2, MVV, TCL and FEV in the observation group after the respiratory function exercise were better than before significantly. The incidence rate of complications in the control group was more than in the observa-tion group. Conclusions Strengthen respiratory function exercise can effective improve the respiratory func-tion for patients with lung cancer when cured by thoractomy, which can promote patients' compliance, and then avoid certain postoperative complications.

Objective: To investigate the clinical value of serum adiponectin in patients with preeclampsia and its relationship with insulin resistance. Methods: From May 2017 to May 2018, 80 cases of preeclampsia diagnosed and treated in obstetrics department of the Second People′s Hospital of Liaocheng were selected in the research.According to the severity of the disease, they were divided into severe preeclampsia group and mild preeclampsia group, with 40 cases in each group, and 40 healthy pregnant women in the same period were selected as the control group.The serum adiponectin level and insulin resistance index (HOMA-IR) were detected and compared among the groups, and the correlation between them was analyzed. Results: The serum adiponectin and HOMA-IR in the severe preeclampsia group were (5.08 ±1.13)mg/L, (3.08 ±1.54), respectively, which in the mild preeclampsia group were (6.55±1.46)mg/L, (2.62±1.34), respectively, which in the control group were (11.67±3.53)mg/L, (1.13±0.53), respectively.there were statistically significant difference among the three groups (all P<0.05). The serum adiponectin level in the severe preeclampsia group was lower than that in the mild preeclampsia group and control group(P<0.05), and the HOMA-IR in the severe preeclampsia group was higher than that in the mild preeclampsia group and control group (P<0.05). The serum adiponectin level in the mild preeclampsia group was lower than that in the control group, and the HOMA-IR was higher than that in the control group, the differences were statistically significant (all P<0.05). The serum adiponectin level of preeclampsia patients with insulin resistance was (4.89±1.25)mg/L, which was significantly lower than that of non-insulin resistance patients[(6.78±1.75)mg/L], and the difference was statistically significant (t=6.254, P<0.05). Pearson correlation analysis showed that serum adiponectin level was negatively correlated with HOMA-IR (r=-0.617, P<0.05). Conclusion The serum adiponectin level and insulin resistance index of preeclampsia patients are significantly decreased, and there is a significant negative correlation between them.

Cellulases are relatively costly enzymes that are sold in large volumes for use in different industrial applications, and a significant reduction in cost will be important for their commercial use in biorefineries. The production of cellulase is a major factor in the hydrolysis of cellulosic materials. Hence it is essential to make the process economically viable. A strain (L-06) with high cellulase activity was screened from rice straw compost and classified as Penicillium decumbens by the analysis of its morphology and 18S rRNA gene sequences. Different conditions of liquid fermentation medium including nitrogen source, carbon source, surfactant, temperature, initial pH, inoculation quantity for the production of cellulase had been studied. The maximal beta-1, 4-glucosidase(BGL) activity was 1662 u/mL which is 1.49 times of the previous and the maximal exo-beta-1, 4-glucanases(CBH) activity was 2770 u/mL which is 1.36 times of the previous, cultured in the optimal condition for three days. And the maximal endo-beta-1, 4-glucanases (EG) activity was 18064 u/mL which is 1.87 times of the previous and the maximal filter paper enzyme(FPase) activity was 4035 u/mL which is 1.47 times of the previous, cultured in the optimal condition for four days. In the optimization experiments, the EG and CBH in the culture condition (pH10) maintained 70% and 43% activity. In the culture condition (50 degrees C) EG and CBH maintained 59% and 68% activity, which showed heat and alkali resistant characteristics.
