Analysis on the status quo of 0-14 years old children′s cross-provincial medical treatment in Shandong province / 中华医院管理杂志

Objective:To analyze the current situation and problems of cross-provincial medical treatment for children in Shandong province, and put forward corresponding countermeasures.Methods:The FUTang Updating medical REcords(FUTURE)database established by Futang Children′s Medical Development Research Center was selected to extract the data of 0-14 years old children who were discharged outside Shandong province from January 1, 2019 to December 31, 2020 and whose current address was in Shandong province, and the data of hospitalized children in a children′s hospital in Shandong province during the same period were selected for comparison. The SPSS 22.0 software was used to establish the database, and statistics and analysis were made on the number of cases, main flow direction, departments, types of diseases and hospitalization cost of children.Results:A total of 13 071 cases accepted cross-provincial medical treatment were included, and the main flow of medical treatment was Beijing Children′s Hospital. The data of 87 742 children admitted to a children′s hospital in Shandong province at the same time were included. The proportion of female and school-age children in children accepted cross-provincial medical treatment was higher than that of local patients, and the hospitalization cost was higher than that of local patients. The main diseases for children seeking medical treatment outside the province were tumors, immune diseases and other serious diseases or chronic diseases, while the main diseases for children seeking medical treatment in the province were respiratory diseases such as pneumonia.Conclusions:The proportion of tumors and immune diseases among children aged 0-14 years accepted cross-provincial medical treatment is relatively high. Hospitals in Shandong province should pay attention to the construction of key specialties, actively develop new technologies and new businesses, and enhance the core competitiveness of hospitals. At the same time, we should improve the medical service system and guide patients to seek medical care reasonably through policies.

[Effect of recombinant human parathyroid hormone 1-34 on mandibular distraction osteogenesis in rabbits].

OBJECTIVE: To explore the effect of recombinant human parathyroid hormone 1-34 [rhPTH(1-34)] on bone regeneration rabbit mandible during distraction osteogenesis (DO). METHODS: 40 Japanese white rabbit (weight 2.0-2.5 kg) were randomly divided into control group and groups. The experimental groups were divided inito 12.5, 25 and 50 µg/kg group according to the dosage of rhPTH (1-34) in each group. Each group involved 10 rabbits, and unilateral DO models were established at the right mandible of the rabbits. From the first day of distraction to the day of execution, the rabbits in the experimental groups were injected subcutaneously rhPTH (1-34) of the corresponding dose respectively, and the rabbits in the control group were injected subcutaneously 2% heat inactivated rabbit serum 1 ml respectively.. Five rabbits in each group were executed respectively at 1 week and 3 weeks after completion of distraction, and the specimens of DO were harvested. The gross observation, X-ray examination, and histological study were performed. RESULTS: Gross appearance: At the first week of consolidation, the dense and opaque white tissue was seen in the distraction gap of the 50 µg/kg group, and the white translucent tissue was seen in the distraction gaps of the rest groups. At the third week of consolidation, the greyish white tissue was seen in the distraction gap of the control group, while the cartilage-like tissue was seen in the buccal side of the distraction gap of the 12.5 µg/kg group, the color of new-formed tissues was close to that of normal bone tissue in the lingual side. The buccal tissue at the edge of the distraction gap of the 25 µg/kg group fitted together with the primary bone tissue in its two sides. It was difficult to distinguish the boundaries between the distraction gap and the bone tissues in its two sides in the 50 µg/kg group. X-ray findings: At the first week of consolidation, a sparse opaque image was seen in the distraction gap of the 50 µg/kg group, and a low-density image was seen in the distraction gap of the rest groups. At the third week of consolidation, a sparse bone image was seen in the control group, and the edge of the bone was not continuous. With the increase of the dose in the experimental groups, the image of the distraction gap became more and more opaque, and the image of the distraction gap in the 50 µg/kg group was close to that of the normal bone tissue. HISTOLOGICAL FINDINGS: At the first week of consolidation, few osteoblasts were present at the edge of the distraction gap of the control group. A large number of bone cells and bone trabecular were present in the distraction gap of the 12.5 µg/kg group, the network of the bone trabecula was present in the 25 µg/kg group, and a few new bones were found in the 50 µg/kg group. At the third week of consolidation, the network of the trabecular bone was present in the distraction gap of the control group, while the network of the bone trabecula was present in the 12.5 µg/kg group, a lot of bone-like tissues in the 25 µg/kg group, and near-mature bone in the 50 µg/kg group. CONCLUSIONS: rhPTH(1-34) can promote the formation of new bone in the distracted gap during mandibular DO in rabbits.

The effect of rosiglitazone on non-alcoholic fatty liver in experimental rats / 中国糖尿病杂志

Objective To investigate the effect of rosiglitazone on non-alcoholic fatty liver (NA and to explore the relationship between insulin resistance and NAFL. Methods Animal model of NAFL was established by feeding Sprague-Dawley rats a high-fat diet for 8 weeks. The model rats were then randomized into rosiglitazone-treated and untreated groups. The animals were sacrificed after being treated with rosiglitazone or vehicle for 4 weeks. The histological changes of liver were examined, and liver function, fasting plasma glucose, fasting serum insulin, serum lipid profile, leptin, and adiponectin were measured. Results As compared with untreated group, hepatic steatosis and liver function were significantly improved in rosiglitazone-treated group. Alanine aminotransferase (ALT) was 54±19 U/L vs 101±24 U/L, aspartic acid aminotransferase (AST) 151±37 U/L vs 198±48 U/L, and alkaline phosphatase (ALP) 87±16 U/L vs 115±39 U/L, respectively (P<0.01). Serum adiponectin level was higher, and serum leptin level and insulin resistance index (HOMA-IR) were lower in rosiglitazone-treated group than in untreated group. HOMA-IR was 6.9±1.8 vs 12.0±1.2 (P<0.01). Serum triglyceride, total cholesterol and low density lipoprotein-cholesterol level were significantly decreased in rosiglitazone-treated group as compared with untreated group (P<0.01). Conclusions Insulin resistance might play important role in the pathogenesis of NAFL. Rosiglitazone effectively reverses NAFL in animal model.
