Objective:To investigate the efficacy and safety of cedilanid in the treatment of severe pneumonia in infants and the value of preventing heart failure.Methods:A total of 80 children with severe pneumonia admitted to Dezhou Maternal and Child Health Hospital from January 2019 to December 2020 were selected and randomly divided into the control group and the observation group, with 40 cases in each group. The control group received comprehensive treatment, while the observation group was treated with cedilanid (0.01 mg/kg, one-time intravenous injection) on the basis of the control group. The efficacy of both groups was observed after 5 d of treatment. The incidence of heart failure, correction time of heart failure, improvement time of symptoms and signs, and length of hospitalization time were compared between the two groups; the inflammatory markers, myocardial markers and arterial blood gas indexes were compared between the two groups before and after the treatment.Results:The total effective rate in the observation group was higher than that in the control group, and the incidence of heart failure in the observation group was lower than that in the control group: 90.0% (36/40) vs. 72.5% (29/40), 32.5%(13/40) vs. 10.0%(4/40), the differences were statistically significant ( χ2 = 4.02, 4.10, P<0.05). The improvement time of symptoms and signs (restlessness elimination, respiratory improvement, heart rate improvement and disappearance of rhonchus in lung) in the observation group were less than those in the control group ( P<0.05). The levels of procalcitonin (PCT) and N-terminal pro-brain natriuretic peptide (NT-ProBNP), myocardial troponin I(cTnI), and creatine kinase isoenzyme (CK-MB) in the observation group after treatment were lower than those in the control group: (6.15 ± 1.03) μg/L vs. (10.85 ± 2.12) μg/L, (112.02 ± 30.09) ng/L vs. (215.39 ± 55.08) ng/L, (0.68 ± 0.17) μg/L vs. (1.12 ± 0.34) μg/L, (19.05 ± 6.11) U/L vs. (28.97 ± 7.82) U/L, P<0.05. The levels of oxygen partial pressure (PaO 2), blood oxygen saturation (SaO 2) and oxygenation index (PaO 2/FiO 2) in the observation group after treatment were higher than those in the control group: (6.15 ± 1.03) μg/L vs. (10.85 ± 2.12) μg/L, (112.02 ± 30.09) ng/L vs. (215.39 ± 55.08) ng/L, (0.68 ± 0.17) μg/L vs. (1.12 ± 0.34) μg/L, (19.05 ± 6.11) U/L vs. (28.97 ± 7.82) U/L, P<0.05. Conclusions:Early application of small dose of cedilanid in infants with severe pneumonia can effectively reduce the occurrence of heart failure, improve the clinical symptoms and blood gas indicators, with significant curative effect, which is worthy of promotion.

Objective: This study aimed to explore the existing knowledge about midwives' views and experiences of providing care for women in the context of task shifting.Methods: We conducted a qualitative systematic review using meta-ethnography to describe the views and experiences of midwives on providing care in the context of task shifting. Comparative textual analysis of published qualitative studies involved translation of first-order key concepts and meanings from included studies to generate second-and third-order concepts. A grid was made to identify core findings and compare them reciprocally. Results: Thirty-six qualitative studies met the inclusion criteria. The literature comprised of 32 first key concepts. Eight second-order constructs emerged, and three third-order interpretations were generated. The three overarching themes were: (1) midwives perceived themselves as providing culturally competent and high quality women-centered care; (2) they valued their profession but saw it as complex and challenging; (3) as health professionals, they reported a variety of organizational, cultural, and professional barriers to providing women-centered care. Conclusions: While performing a specific task in the task shifting context, midwives perceived their crucial roles and responsibilities, along with achieved value and reward. However, due to a range of existing barriers, the caring task posed great challenges in completely implementing women-centered care. It is essential for systems to identify and eliminate these barriers early, to consider midwives' emotional well-being, and to develop overall strategies to better support the midwifery workforce. Policy makers and administrators should establish a supportive environment to facilitate midwives to perform women-centered caring tasks in more effective and efficient ways.

OBJECTIVE: To explore the suitable process for prenatal screening and diagnosis for women with advanced maternal age. METHODS: From January 2014 to November 2017, the indications and distributions of prenatal diagnosis for women with advanced maternal age only or accompanying with positive maternal serum test screening and non-invasive prenatal testing (NIPT), abnormal fetal ultrasound, one harboring chromosomal abnormalities or anomalous reproductive history were analyzed. The rate of fetal chromosomal abnormalities was compared between different groups. RESULTS: The 351 pregnant women with fetal chromosomal abnormalities have included 196 cases with advanced maternal age, 26 with positive maternal serum test, 96 with high-risk by NIPT, 14 with abnormal fetal ultrasound, 15 with one partner harboring chromosomal abnormalities, and 4 with anomalous reproductive history. Assuming that all pregnant women had undergone maternal serum test screening or NIPT without amniocentesis, the detection rate of fetal chromosome abnormality would be 51.0% and 69.2%, respectively. However, should these women have received both tests, the detection rate would be as high as 84.6%. Should those with one partner harboring chromosomal abnormalities undergone maternal serum test screening or NIPT without amniocentesis, the detection rate of fetal chromosomal abnormality would only be 6.7%. CONCLUSION Should pregnant women with advanced maternal age undergo both maternal serum test and NIPT, the detection rate of fetal chromosomal abnormality will be higher than those receiving only maternal serum test screening or NIPT. Couples with one partner harboring chromosomal abnormalities should undergo prenatal diagnosis by amniocentesis.

Objective: To detect the expression of CRLF2 in adult Ph negative acute B lymphocytic leukemia (B-ALL) in newly diagnosed cases, and to investigate the relationship between CRLF2 and the general clinical characteristics, efficacy and prognosis. Methods: 103 cases of newly diagnosed adult B-ALL patients were investigated from Apr 2016 to Dec 2017 in the Department of Hematology, Henan Cancer Hospital. Bone marrow samples was used to detect the expression of CRLF2 in leukemic cells. The expression of CRLF2 ≥20% was defined as CRLF2-high group and <20% was defined as CRLF2-low group. The clinical characteristics and prognosis of the two groups were compared. Results: The Median overall survival (OS) and disease free survial (DFS) in CRLF2-high group were 9.0 months and 4.25 months, respectively. CRLF2-low group were 15.5 months and 10.25 months, respectively. There was a statistically significant difference in median OS and DFS between the two groups (P=0.007, P=0.000) . The 18-month OS and DFS in CRLF2-high group were 38.6% and 25.1%, respectively. CRLF2-low group were 57.8% and 42.3%, respectively. Multivariate analysis showed high expression of CRLF2 was an independent risk factor for OS (HR=2.991, 95% CI 1.429-6.261, P=0.004) and DFS (HR=2.374, 95%CI 1.146-4.960, P=0.041) in patients. Conclusion Patients with high expression of CRLF2 had poor prognosis.

OBJECTIVE: To analyze the clinical significance of ocular vestibular evoked myogenic potentials (oVEMP) and cervical vestibular evoked myogenic potentials (cVEMP) in primary unilateral benign paroxysmal positional vertigo (BPPV). METHOD: Fifty-two patients with unilateral primary BPPV (BPPV group) and 38 normal subjects (control group) received ocular vestibular evoked myogenic potential (oVEMP) and cervical vestibular evoked myogenic potential (cVEMP) test using tone burst stimuli. The response rate, latency and amplitude were analyzed. RESULT: In BPPV group, the response rate of oVEMP was 46.15% in lesioned side and 48.08% in healthy side, respectively. The response rate of cVEMP was 67.31% in lesioned side and 65.38% in healthy side, respectively. In control group, the response rate on the left ear was 84.21% for oVEMP and 92.11% for cVEMP. On the right ear, was 81.58% for oVEMP and 94.74% for cVEMP in control group, there was no significant difference in cVEMP and oVEMP P1, N1 N1-P1 latency and amplitude between left and right ear. The interaural amplitude ratio and asymmetry of cVEMP and oVEMP was significantly different between BPPV group and control group (P<0.05). CONCLUSION Unilateral primary BPPV with bilateral impaired vestibular otolith pathways function can be objectively evaluated by oVEMP and cVEMP detection. Abnormal oVEMP responses were more frequently detected than cVEMP.

Objective To determine the serum KL-6 level in patients with pancreatic carcinoma and investigate its diagnostic value. Methods The data of 53 pancreatic carcinoma (PC) patients; 68 chronic pancreatitis (CP) patients and 51 patients with high risks of pancreatic cancer (HR) with complete follow-up data were studied, and 50 healthy volunteers were used as controls. ELISA was used to measure the serum levels of KL-6, MUC4, and CA50. Radioimmunoassay methods were used to measure the serum CA19-9 levels. The sensitivity and specificity of KL-6 for the diagnosis of PC were determined, and the relationship between its levels and clinicopathologic parameters, patients' outcome were analyzed. Results The serum KL-6 levels were (753±548), (135±93), (105±55) and (99±50) U/ml in PC group, CP group, HR group and control group, and the value in PC group was significantly higher than those in other 3 groups (P <0.01). Using >232 U/ml as the cut-off point, the sensitivity and specificity of KL-6 for the diagnosis of PC was 96% and 94%. Using >244 U/ml as the cut-off point, the sensitivity and specificity of KL-6 for the diagnosis of PC was 97% and 91%. The clinical value of KL-6 was higher than those of CA19-9, CASO and MUC4. The serum level of KL-6 was not associated with clinicopathologic parameters. The median survival of patients with serum level of KL-6 =300 U/ml was (9.3 ±1.2) months, which was significantly longer than that in patients with serum level of KL-6 >300 U/ml [ (4.6 ±0.7) months, P =0.006]. Conclusions KL-6 might be a useful serological marker of pancreatic cancer, and it may play a role in the differential diagnosis between pancreatic cancer and chronic pancreatitis.

Objective To analyze the relationship between blood glucose level, blood pressure and weight with pancreatic cancer genesis. Then to explore the metabolism associated risk factors in pancreatic cancer genesis. Methods Form December 2002 to September 2009 in Ruijin Hospital, 548 pancreatic cancers with pathology diagnosis after pancreatectomy were collected for the study with retrospective analysis method. The association of pancreatic cancer with blood glucose level, blood pressure, weight and other metabolic factors were analyzed. Results With principal component analysis, it suggested that there were strong correlation between blood glucose level, blood pressure and weight index (BMI) increasing with pancreatic cancer. The contribution rates were 3. 614%,25. 236%, 15. 418% and 12. 918%, respectively. Single factor analysis indicated that the association between pancreatic cancers and new onset diabetes mellitus (duration≤ 2 years) was stronger than that of long-term diabetes mellitus. The occurrence rate of pancreatic cancer in patients with long-term diabetes whose blood glucose level was not well controlled recently while well controlled previously (44.6 % ) was significant hister than that in patients without diabetes (5. 6% , P＜0.05). The fasting blood glucose level of these PC patients ( 13.87± 3. 49 mmol/L) was significantly higher than new onset and other long-term diabetes patients, the comparative risk was 13.46 (95% CI 4. 560,39. 731). BMI increasing was a risk factor of pancreatic cancer, but there was no significant statistical difference between risk degree and BMI increasing level. All above metabolic diseases were risk factors of pancreatic cancer, but for pathology, location and stage of pancreatic cancer there was no statistical difference in theses factors. Conclusion This study suggested diabetes, BMI increasing and hypertension were high risk factors of pancreatic cancer genesis. New onset and long-term diabetes patients whose blood glucose not controlled well recently should be watched carefully for pancreatic cancer. Early treatment and intensive follow-up of metabolic disease might be helpful to early diagnosis and prognosis of pancreatic cancer.
