Objective To evaluate the effect of care bundle in improving the hand hygiene compliance of neonatal intensive care unit staffs. Methods We implemented care bundle strategy through QCC activity: strengthening training and management to improve the hand hygiene awareness of the medical staffs, environmental and workflow reform,improving the hand washing method and facilities and creating hand hygiene atmosphere, all staffs participated and supervised each other to ensure right way of washing hands. The hand hygiene compliance rate of medical staff after entering the neonatal intensive care unit (NICU) and before touching the neonates before and after the intervention were compared. Results After care bundle intervention, the hand hygiene compliance rate of medical staff after entering the NICU and before touching the neonates raised obviously from 32.1% to 97.4% and from 92.0% to 99.3%. The occurrence of nosocomial infection reduced from 2.22% to 1.38%. Conclusions Care bundle can significantly improve the hand hygiene compliance of medical staff, and prevent nosocomial infection.

Objective: To develop a narcissistic personality questionnaire for non-clinical Chinese people. Methods: The questionnaire was developed on the basis of data from open questionnaire, interview and Narcissistic Personality Inventory. Six hundred and twelve participants finished a Narcissism Questionnaire, Self-Esteem Scale, Trait Anxiety Inventory, and Satisfaction with Life Scale. Results: ①An exploratory factor analysis revealed three factors labeled authority, superiority, and selfadmiration; and a confirmatory factor analysis suggested that the goodness-of-fit indexes of this three-factor model was satisfactory; ②Cronbach alpha coefficients of narcissism questionnaire and its three factors ranged from 0.796 to 0.929; ③Consistent with previous studies, males were more narcissistic than females; ④Narcissism was pos- itively correlated with self-esteem, negatively correlated with anxiety and was not associated with satisfaction of life; selfesteem mediated the relationship between narcissism and anxiety. Conclusion: The self developed questionnaire illustrated satisfactory internal consistency reliability, construct validity, and criterion-related validity.

OBJECTIVE: To explore the clinical characteristic, the CT, MRI features, diagnosis and treatment of low grade myofibroblastic sarcoma in head and neck. METHOD: Six cases of low grade myofibroblastic sarcoma in head and neck were diagnosis and reviewed retrospectively. Routine preoperative CT and MRI examination were performed. RESULT: All cases were operated one case with radiotherapy before operation was given with a total dose of 60 Gy. The patients were follow-up for 6 months to 5 year and no recurrence was found. No complications occurred in 6 cases. CONCLUSION It has been confirmed in this research that LGMS is a low-grade malignangt tumor. It was difficult to make early diagnosis through frozen section. The final diagnosis depend on paraffin section and immunohistochemisty. Extended local excision with tumor-free margin is the treatment of choice.

Objective To investigate the current situation of iodine deficiency disorders and the effect of control measures in Changzhou City, Jiangsu Province, and to provide a basis for making up targeted control measures for iodine deficiency disorders. Methods In 2012, proportional probability sampling method(PPS) was used to select 30 primary schools in seven counties of Changzhou City;50 students aged 8-10 in each school were randomly selected to examine thyroid, and their urine and household salt samples were collected to detect iodine. Thirty pregnant and 15 lactation women were selected to detect their urine iodine in the town where the school was located in. Two drinking water samples were collected to detect iodine in the village where the school was located in. The questionnaire survey of health education was carried out among the children and the housewives. Results A total of 1 500 children were surveyed, and the rate of goiter was 0.07%(1/1 500); the median of urinary iodine was 224.81 μg/L. Five hundred and seventy-two pregnant women and 328 lactation women were surveyed, and the median of urinary iodine was 148.93 μg/L and 147.48 μg/L, respectively. Fifteen hundred salt samples were detected, and the coverage rate of iodized salt was 99.47%(1 492/1 500); the edible rate of qualified iodized salt was 97.67%(1 465/1 500); and the median of salt iodine was 25.46 mg/kg. Sixty water samples were collected, and the median of water iodine was 3.63 μg/L. The health education awareness rates were 77.8%(2 100/2 700) and 88.0%(396/450) of students and housewives, respectively. Conclusion The control effect of iodine deficiency disorders is significant in Changzhou City, and monitoring of iodine nutrition level of special populations should be strengthened.

SAαt2,6 and SAα2,3 linked sialic acid molecules on epithelial cell membrane served as receptors for influenza virus, which axe specifically recognized by human and avian influenza viruses, respectively. The distribution of these two species of sialic acids in human respiratory tract from different anatomical sites and different age groups was investigated. The results showed that SAα2,3Gal species was prevalent in respiratory bronchiole and lung alveolar epithelium, but was infiequent in trachea, bronchus and bronchiole. On the contrary, the SAα2,6Gal species was more common in the trachea and bronchus and to a lesser degree in the alveolar epithelium. When compared the expression levels of SAα2,6Gal and α2,3Gal in the respiratory tract among different age groups, no significant difference was found. In the ex vivo H5N1 virus infection study, alveolus epithelium were found to be more susceptible to avian influenza than trachea and bronchus epithelial cells. These results suggest that the human respiratory tract, to some extent, is permissive for avian influenza viruses. The currently-observed limited human to human transmission of H5N1 virus may be associated with the different abundance of SAα2,3Gal linkages in human upper respiratory tract among individuals.

Qi arrival is the meridian qi response to acupuncture stimulation. Through analyzing the relevant concepts of qi arrival and summarizing the general understanding of it in clinic and on the basis of the collection of the relevant literature at home and abroad on the determination of qi arrival and its strength, the characteristics are analyzed on the present method and the method for the determination of qi arrival and its strength is discussed in terms of the results in the needling sensation scale. It is believed that the needling sensation and its strength can be used to determine whether the qi is arrived or not and its strength. The components of different types of needling sensation are much better applicable for the analysis on the characteristics and rules on the influence on qi arrival. This method is in compliance not only with the theoretic connotation of qi arrival, but also with the clinical general understanding, which lays the foundation for the analysis on the scale results.

Objective To explore the optimized method of venous anastomosis for right donor kidney transplantation in rats.Methods Sprague Dawley (SD) rats were used as donors and recipients for homologous rat kidney transplantation.Both bilateral kidneys were harvested from the donor rats (n =45).Ninety rats were used as recipients and divided into 4 groups according to randomly digital table:In groups AC (n =15 each),the right donor kidneys were transplanted into the left nephridial pit of recipients,and endto-side,venous bypass and modified end-toend (donor's proximal end of vena cava was anastomosed to recipients renal Vein followed by ligation of its distal end) venous anastomosis was done,respectively; In the control group (n =45),the left donor kidneys were transplanted into the same side of the recipients,and the conventional end-to-end venous anastomosis was used.Then the intra-operative findings,successful operation rate and postoperative complications were compared between two groups.Results The venous anastomosis time in group B was longer than in groups A,C and control group (P＜0.05),which significantly increased warm ischemia time of donor kidneys and operative time of recipients (P＜0.05).The venous anastomosis time,warm ischemia time of donor kidneys and operative time of recipients showed no significant difference between groups A or C and control group (P＞0.05).The successful operation rate in group C (93.3％)was similar to that in control group (86.7％) (P＞0.05),but higher than in group A (53.3％) and group B (53.3％) (P＜0.05).There was no significant difference in postoperative complications between group A and group C.Conclusion For right donor kidney transplantation,the method of harvesting the right donor kidney with a part of vena cava,and then anastomosing the proximal end to recipients renal vein and ligating the distal end,is highly feasible,efficient and economic.

Objective:To investigate the impact of abnormal patterns of 75 g oral glucose tolerance test (OGTT) in the second trimester on the risk of large for gestational age (LGA) newborn deliveries.Methods:General clinical data and OGTT results of 66 290 pregnant women who received regular prenatal care and delivered in Guangdong Maternal and Child Health Hospital from December 24, 2016 to July 26, 2022 were collected. According to the results of OGTT, the pregnant women were divided into 8 groups: normal blood glucose group (normal fasting blood glucose, 1-hour and 2-hour after oral glucose, 54 518 cases), gestational diabetes mellitus (GDM) 0 group (only abnormal fasting blood glucose, 1 430 cases), GDM 1 group (only abnormal blood glucose at 1-hour after oral glucose, 2 150 cases), GDM 2 group (only abnormal blood glucose at 2-hour after oral glucose, 3 736 cases), GDM 0+1 group (both fasting blood glucose and 1-hour after oral glucose were abnormal, 371 cases), GDM 0+2 group (both fasting blood glucose and 2-hour after oral glucose were abnormal, 280 cases), GDM 1+2 group (abnormal blood glucose at 1-hour and 2-hour after oral glucose, 2 981 cases) and GDM 0+1+2 group (abnormal fasting blood glucose, 1-hour and 2-hour after oral glucose, 824 cases). Multivariate logistic regression was used to analyze the effects of different abnormal OGTT patterns on LGA. In addition, the blood glucose measurements at the three time points of OGTT were combined and used as continuous variables in the receiver operating characteristic (ROC) curve to evaluate the predictive value of each blood glucose measurement mode for LGA and the area under the curve (AUC) was compared.Results:(1) Multivariate logistic regression analysis showed that the risks of LGA were significantly increased in GDM 0 group ( OR=1.76, 95% CI: 1.50-2.08; P<0.001), GDM 0+1 group ( OR=2.29, 95% CI: 1.72-3.04; P<0.001), and GDM 0+1+2 group ( OR=1.98, 95% CI: 1.61-2.43; P<0.001). (2) ROC curve analysis showed that fasting blood glucose, 1-hour after oral glucose, 2-hour after oral glucose, fasting+1-hour after oral glucose, fasting+2-hour after oral glucose, 1-hour+2-hour after oral glucose, and fasting+1-hour+2-hour after oral glucose had certain predictive value for LGA (all P<0.001). The AUC of fasting blood glucose measurement was higher than that of 2-hour blood glucose measurement in predicting LGA, and the difference was statistically significant ( P<0.05). There was no significant difference in the AUC between fasting blood glucose and other blood glucose measurement modes for predicting LGA (all P>0.05). Conclusions:In the abnormal OGTT patterns, pregnant women with abnormal fasting blood glucose, abnormal fasting+1-hour after oral glucose, and abnormal fasting+1-hour+2-hour after oral glucose have an increased risk of LGA. Fasting blood glucose measurement is of great significance for the prediction of LGA, and could be used as an optimal indicator to evaluate the risk of LGA in clinical practice.

Purpose: This study aims to explore whether neoadjuvant chemotherapy with immunotherapy (NACI) leads to different tumor shrinkage patterns, based on magnetic resonance imaging (MRI), compared to neoadjuvant chemotherapy (NAC) alone in patients with triple-negative breast cancer (TNBC). Additionally, the study investigates the relationship between tumor shrinkage patterns and treatment efficacy was investigated. Methods: This retrospective study included patients with TNBC patients receiving NAC or NACI from January 2019 until July 2021 at our center. Pre- and post-treatment MRI results were obtained for each patient, and tumor shrinkage patterns were classified into three categories as follows: 1) concentric shrinkage (CS); 2) diffuse decrease; and 3) no change.Tumor shrinkage patterns were compared between the NAC and NACI groups, and the relevance of the patterns to treatment efficacy was assessed. Results: Of the 99 patients, 65 received NAC and 34 received NACI. The CS pattern was observed in 53% and 20% of patients in the NAC and NACI groups, respectively. Diffuse decrease pattern was observed in 36% and 68% of patients in the NAC and NACI groups. The association between the treatment regimens (NAC and NACI) and tumor shrinkage patterns was statistically significant (p = 0.004). The postoperative pathological complete response (pCR) rate was 45% and 82% in the NAC and NACI groups (p < 0.001), respectively. In the NACI group, 17% of patients with the CS pattern and 56% of those with the diffuse decrease pattern achieved pCR (p = 0.903). All tumor shrinkage patterns were associated with achieved a high pCR rate in the NACI group. Conclusion Our study demonstrates that the diffuse decrease pattern of tumor shrinkage is more common following NACI than that following NAC. Furthermore, our findings suggest that all tumor shrinkage patterns are associated with a high pCR rate in patients with TNBC treated with NACI.
