This paper reports the nursing care of 7 patients with liver cirrhosis during pregnancy and childbirth. During the pregnancy period,nursing care focused on integrated management,monitoring of the dynamic changes of liver cirrhosis and individualized care. During delivery and perioperative period,supportive treatment was implemented and complications such as upper gastrointestinal hemorrhage,postpartum hemorrhage and infections were prevented. The 7 patients got through the perinatal period safely.

Objective To explore the establishment of skin photoaging model and the protective effects of nitroxide tempol on skin in guinea pig. Methods The guinea pig skin photoageing model was established by using solar-simulaten radiation (SSR). Dermal structure was observed with hematoxylin-eosin staining. The structure and expression of elastic fiber were analyzed by Weigert's staining. The uhrastructure of dermal fibroblasts and elastic fiber were observed by electron microscopy. Tempol was used before each exposure at the concentration of 5 mg/ml or 0. 5 mg/ml, and the protective effects of tempol on skin were assessed. Results After seventeen weeks' exposure, there was typical "solar elastosis" damage in the upper dermis. Mature elastic fibers were severely degraded and there was large amount of elastotic material accumulated in the upper dermis. Dermal fibroblasts appeared metabolically hyperactive and mitochondria in the cells were damaged. Some cells even broke up. Tempol at the concentration of 5 mg/ml or 0. 5 mg/ml could prevent photodamage of the photoageing model in the dermis, and Tempol at the concentration of 5 mg/ml had stronger protective effects. Conclusions Guinea pig can be applied as an useful animal model of skin photoageing. Antioxidant tempol has photoprotective effects on photodamage of the photoageing model in guinea pig and can be used as an anti-photoageing agent.

Objective To study the status quo of nursing human resource configuration and structure of neonatology department in China's economically developed areas.Methods Using judgment sampling and multi-stage stratified sampling,investigations were conducted by the self-designed questionnaire in letter in 2012.Results In 2012,both the bed nurse ratio(1:0.79) and doctor nurse ratio (1: 1.22) met the Health Ministry's standards (1:0.58-0.61 and 1: 2) respectively.Age distribution of neonatology nursing staff was from 25 to 34 years old (55%).The distribution of wordng experience was average.Nurses with junior college degree as the main body took up 48%,with primary title as the main body 66%,and the appointment system accounted for 42%.The nursing personnel with young ages,senior skilled,higher education degree,and advanced titles were concentrated in Grade Ⅲ-A hospitals and public hospitals of women and children.In terms of distribution equity,two Gini coefficients of geographical and population distribution were both less than 0.35 and near zero,which indicated relatively perfect equity.Conclusions The stock and per capita of neonatology nursing human resources in China's economically developed areas were insufficient in the long run and showed imbalanced allocation among hospitals with different levels.The allocation structure failed to meet the needs of nursing disciplinary development.

Objective:To understand the viral genomic characteristics of a 2019-novel coronavirus (2019-nCoV) strain in the first COVID-19 patient found in Hangzhou, China.Methods:Viral RNA was extracted in throat swab and sputum sample of the patient and was performed real-time reverse transcription PCR detection and obtained viral genome by high-throughput sequencing method. Phylogenetic analysis was conducted using 29 2019-nCoV genomes and 30 β-coronavirus genomes deposited in NCBI GenBank. Fifteen genomes from Wuhan were grouped by mutation sites and others were identified by Wuhan's or specific mutation sites.Results:A 29 833 bp length genome of the first 2019-nCoV strain in Hangzhou was obtained, covering full length of the coding regions of coronavirus. Phylogenetic analysis showed that the genome was closest to the genome of a bat SARS-like coronavirus strain RaTG13 with an identity of 96.11% (28 666/29 826). Among the genes between two genomes, E genes were highly conserved (99.56%), while S genes had lowest identity (92.87%). The genome sequence similarities among 29 strains from China (Hangzhou, Wuhan, and Shenzhen), Japan, USA, and Finland, were all more than 99.9%; however, some single nucleotide polymorphisms were identified in some strains.Conclusion:The genome of Hangzhou 2019-nCoV strain was very close to the genomes of strains from other cities in China and overseas collected at early epidemic phase. The 2019-nCoV genome sequencing method used in this paper provides an useful tool for monitoring variation of viral genes.

Descriptive epidemiological methods were used to analyze the epidemiological characteristics of the local cluster of COVID-19 in the logistic park of Yuhang District in Hangzhou in March 2022. The cluster epidemic was detected by a case who actively visited the fever clinic. The epidemic lasted for 8 days, and a total of 58 cases (53 workers, 2 students, 1 farmer, 1 teacher and 1 unemployed) were found, including 40 males and 18 females. The age was (33.29±12.22) years. There cases were mainly in Yuhang District (48 cases, 82.77%) and Shangcheng District (7 cases, 12.07%) of Hangzhou. The real-time regeneration number peaked at 2.31 on March 10 th and decreased to 0.37 on March 15 th. The sequencing result of the indicated case was 100% homologous with the sequence uploaded from South Korea on March 4 th, 2022.
