ABSTRACT
Adhering to and strengthening the Party′s overall leadership is the primary guarantee for promoting the high-quality development of public hospitals. How to comprehensively strengthen the internal audit led by the Party and improve the efficiency of internal audit governance in public hospitals, so as to play the role of internal audit in effectively promoting the high-quality development of public hospitals, is an urgent problem to be solved. The author analyzed the current situation and practical reasons of the internal audit under the Party′s control in public hospital in China, constructed the mechanism framework of the internal audit under the Party′s control, and further analyzed and processed the implementation path of the internal audit under the Party′s control from three aspects: establishing the Party Committee Audit Committee to strengthen the top-level design of the internal audit, linking the three major audits to give full play to the supervision force of the internal audit, and implementing the eight major restructuring to achieve the closed-loop governance of the internal audit under the Party′s control.
ABSTRACT
Retinal blood vessels are the only circulatory system that can be observed under non-invasive conditions. By observing the morphological changes of retinal blood vessels, the changes of blood circulation can be indirectly reflected. The occurrence, development and evolution of different diseases can be discovered. With the development of new detection technologies, especially the wide application of fundus photography and optical coherence tomography, a more intuitive and non-invasive quantitative index is provided for retinal vascular measurement. It is important for the diagnosis, guiding treatment and follow-up of related vascular diseases. This article reviews the development of retinal vessel diameter measurement methods and related applications in clinical diagnosis and treatment.
ABSTRACT
To investigate the effect and mechanism of psoralen on calvarial osteoblasts injuries caused by tricalcium phosphate (TCP) wear particles in vitro. Primary osteoblasts were obtained from the calvaria of neonatal SD rat by the series of digestion and were identified with ALP staining. Calvarial osteoblasts were treated with TCP wear particles for 48 h to establish the in vitro model of osteoblasts injuries. The rat osteoblasts were randomly divided into control group, TCP wear particles (0.1 mg/ml) group, psoralen treated (at the concentrations of 10, 10, 10 mol/L) groups. WST assay and the flow cytometry were used to detect the cell viability of osteoblasts and apoptosis, respectively. Chemical colorimetry was performed to examine ALP activity of osteobalsts. When the osteoblasts were treated for 14 day, mineral nodules formation was observed with alizarin red S staining. Western blot was applied to examine protein expressions of glucose regulated protein78/94(GRP78/94), inositol dependent enzyme 1 alpha (IREα), spliced X-box binding protein 1 (XBP1s) and phosphorylated c-Jun N-terminal kinase (p-JNK) in calvarial osteoblasts. Compared with control group, the cell viability of osteoblasts, ALP activity and mineral nodules formation in TCP group were decreased significantly (P＜0.05), while the percentage of apoptosis and protein expressions of GRP78/94, IRE1α, XBP1 and p-JNK were obviously increased in calvarial osteoblasts (P＜0.05). Compared with TCP group, the injuries of calvarial osteoblasts and cell apoptosis in psoralen treated groups were obviously decreased (P＜0.05), and the expression levels of GRP78/94, IRE1α, XBP1 and p-JNK were down-regulated remarkably (P＜0.05). Psoralen prevents osteoblasts injuries caused by TCP wear particles through IRE1α-XBP1s-JNK signaling pathway activation.

Objective To explore the impact of family single room practices in NICU on maternal anxiety and breastfeeding status and neuropsychological development in preterm infants. Methods One-hundred NICU-born preterm infants were divided into the experimental group (n= 48) and the control group (n=52) according to random number table. Neonates in the experimental group were guaranteed parental care in the family ward for at least 4 hours a day during hospitalization in NICU, while the control group used a traditional video-based approach for daily scheduled visits. Finally, the results of exclusive breastfeeding, nosocomial infection, maternal anxiety, parental satisfaction, and full-term NBNA score after correction of gestational age were collected and recorded. Results The rates of exclusive breastfeeding were 82.50%(33/40),42.50%(17/40)during hospitalization and six months old in the experimental group, and 17.07%(7/41),12.20%(5/41)in the control group. The difference between the two groups was statistically significant during hospitalization and at 6 months of age (χ2=32.25, 9.40,P <0.01). The score of maternal anxiety was 33.00(31.00, 41.75)in the experimental group, and 43.00(34.50, 46.00)in the control group. The difference between the two groups was statistically significant (Z=-2.97, P =0.003).The NBNA score in the experimental group was 38.50(38.00, 40.00), and 37.00(36.00, 39.00)in the control group. The difference between the two groups was statistically significant(Z=-2.86, P<0.01). Conclusions The development of family ward is conducive to raising the rate of exclusive breastfeeding, reducing the incidence of nosocomial infection, relieving the anxiety of mother-infant separation and enhancing the satisfaction of parents, which can promote the behavioral and neuropsychological development of preterm infants.

ABSTRACT
The 24 h normal developing zebrafish embryos were used to evaluate the acute toxicity and the compounds of respective fractions were analyzed by UFLC-Q-TOF-MS simultaneously. Nine concentration groups with respective concentration and a blank control group were designed for each fraction to investigate their effect on survival rates of zebrafish embryos 96 h after drug administration, and calculate the median lethal concentration (LC₅₀) of different fractions to zebrafish embryos. The results showed that all of the fractions had acute toxicity to zebrafish embryos except VEKD, and the order was as follows: VEKB, VEKC, VEKA and VEKD. According to the results of UFLC-Q-TOF-MS, the chemical ingredients contained in VEKB and VEKC were mainly composed of ingenane-type and japhane-type diterpenoids, respectively. It could be speculated that japhane-type diterpenoids might be the active compounds with lower toxicity associated with the results of toxicity study, providing some references for the further research on effective material basis of Kansui stir-baked with vinegar according to the principle of "drastic medicine, no death risks".

OBJECTIVE@#To evaluate the efficacy and safety of a short course of nebulized budesonide via transnasal inhalation in chronic rhinosinusitis with nasal polyps.@*METHOD@#Thirty patients with severe eosinophilic nasal polyps were randomized into experimental group (n=15) and control group (n=15). The experimental group received nebulised budesonide suspension (1 mg twice daily) via transnasal inhalation for one week and control group-received budesonide nasal spray (256 microg twice daily). Visual analogue scales (VAS)of nasal symptoms (including nasal obstruction, nasal discharge, loss of smell, and headache/facial pain) and endoscopic polyp scores (Kennedy scores) and morning serum cortisol concentration were performed to both groups before and after the treatment.@*RESULT@#Nebulized budesonide inhalation caused a significant improvement in all nasal symptoms especially nasal obstruction (baseline: 8.4 +/- 0.7; after treatment: 4.0 +/- 0.8, P<0.01) and reduced polyp size compared with before treatment. Additionally, the patients treated with nebulized budesonide showed more obvious improvement in nasal symptoms and polyp size than control group. The morning serum cortisol concentration was mild decreased after one week treatment in nebulized steroid group [baseline: (17.6 +/- 2.4) microg/dl, after treatment: (14.8 +/- 2.6) microg/dl, P<0.01], but all values still were located in normal range (normal range: 5-25 microg/dl).@*CONCLUSION@#A short course of nebulized budesonide transnasal inhalation can rapidly improve nasal symptoms, reduce polyp size, and does not cause obvious HPA axis suppression. Based on these, it is recommend that transnasal inhalation with nebulized budesonide suspension should be performed as a pre-operative routine in patients with nasal polyp.

Objective To investigate the prevalence and pattern of androgenetic alopecia (AGA) in Shanghai through a community-based survey. Methods A cluster sampling survey was done among the residents in Beixinjing Community, Changning District, Shanghai. All the subjects were asked to fill a questionnaire to provide their general information, including sex, age, native place, physical status, life habit, family history, etc. The diagnosis of AGA was made by dermatologists. To determine the pattern of hair loss,Norwood-Hamilton classification system and Ludwig classification system were used for male AGA and female AGA, respectively. All the data were statistically analyzed by EpiData and SPSS11.5 software. Results Totally, 7056 subjects completed the questionnaire, including 3519 males and 3537 females, and the response rate was 72.5%. AGA was diagnosed in 809 patients, consisting of 701 males aging from 19 to 91 years (mean 64.16±11.9 years) and 108 females aging from 35 to 91 years (mean 70.46±18.89 years). The standardized prevalence (SP) was 9.47% in total, 15.73% in males and 2.73% in females; the difference was significant between males and females (χ2=356.00, P<0.001). A family history of AGA was observed in 52.7% of all subjects including 391 (55.78%) males and 35 (32.41%) females. Type Ⅲ vertex involvement was the most common type in men aging from 20 to 70 years old, and type Ⅵ in those over 70 years old. Grade Ⅰ and Ⅱ predominated in female AGA. Conclusions The results of this survey indicate that the prevalence of AGA is remarkably higher in men than that in women. Furthermore, the prevalence is steadily increased with advancing age in Shanghai.
