The "Medium and Long-term Plan for the Prevention and Control of Chronic Non-communicable Diseases in Shanghai (2018-2030)" was officially released in August 2018.From the perspective of public health, this paper analyzes the background of the plan from the epidemic situation, response and challenges Shanghai City is facing, expounds the comprehensive prevention and control system of chronic diseases including four functional systems, and explains the key preventive and control measures on the different stages of chronic diseases, comparing the evaluation indicators with those of the national plan.This paper will help to better understand the new blueprint for the prevention and control of chronic diseases in Shanghai in the next ten years.

OBJECTIVETo compare the clinical effects of two methods of internal fixation in treating unstable femoral intertrochanteric fractures in elderly patients.

METHODSFrom August 2009 to August 2014, 68 elderly patients with unstable femoral intertrochanteric fracture treated with locking proximal femur plate and auxiliary short reconstructed plate (reconstructing calcar group) and proximal femoral nail antirotation (PFNA group) with clinical course from 1 to 3 days were retrospectively analyzed. In reconstructing calcar group, there were 30 patients including 8 males and 22 females, aged from 63 to 85 years old with an average of (73.41±5.12) years old, the fractures were classified to type AO 31-A2.2 in 12 cases, A2.3 in 11 cases, A3.3 in 7 cases according to AO/ASIF classification. In PFNA group, there were 38 patients including 10 males and 28 females, aged from 65 to 90 years old with an average of (74.26±4.53) years old, the fractures were classified to type AO 31-A2.2 in 15 cases, A2.3 in 13 cases, A3.3 in 10 cases. All fracture were caused by injury, leading pain and swelling. Femoral intertrochanteric fracture was confirmed by X ray films. The data of each group were collected for statistical analysis on the following aspects: the incision length, operation time, blood loss volume, postoperative partial weight bearing standing time, clinical healing time of fracture, postoperative complications, and hip functional score of Harris.

RESULTSAll incisions were healed at stage I. In the aspect of postoperative complications, there were 1 case of screw blade cutting and 1 case of deep venous thrombosis in PFNA group; there was 1 case of deep venous thrombosis in the reconstructing calcar group (²=0.000,=1.000). Patients were followed up from 20 to 24 months with an average of 22.5 months. There were no significant in postoperative partial weight bearing standing time, postoperative complications, hip functional score of Harris between two group. There were significant in the incision length, operation time, blood loss volume, clinical healing time of fracture. In the incision length, operation time, blood loss volume, clinical healing time of fracture, the PFNA group was significantly differently less than that of the reconstructing calcar group (<0.001). In the clinical healing time of fracture, the PFNA group was significantly differently less than that of the reconstructing calcar group (<0.05).

CONCLUSIONSFor the treatment of unstable femoral intertrochanteric fractures in elderly patients, reconstructing calcar and PFNA are both effective, and proximal femoral intramedullary nails may be the best choice, which can be simpler operation, smaller incision and less healing time.

ObjectiveThere are few reports about abnormal oligonucleotide binding fold domain protein genes (OBGs) affecting the initiation of DNA replication in hepatocellular carcinoma through the microchromosome maintenance (MCM) complex. This study aims to explore the roles of reverse-transcription-related genes (RTGs) in Hepatocellular Carcinoma cells (HCC) and the correlation between gene polymorphisms and abnormal gene expression.Methods We created a mouse model by injecting hepatocellular carcinoma cell line H22 (logarithmic growth phase) and dissected the tumor bodies from tumor-forming mice. The control group was treated by isotonic saline without H22. The healthy liver tissue cells were taken from the control mice. The total RNA of the H22 group and control group were extracted, and differentially expressed genes were analyzed. Screening of differentially expressed reverse transcription-related DEGs (RDEGs), GO and KEGG analysis of RDEGs. The interaction analysis of RDEGs encoded proteins, and the correlation analysis of RDEGs polymorphism and gene expression.ResultsThere were 193 differentially expressed RTGs in HCCs, which were involved in two biological procedures, three cell components, one molecular function, three signal pathways, and three functional sites; Its function is mainly concentrated in DNA replication, especially the construction of MCM complex and telomere complex in which OBGs participate in the initiation of replication. Most related genes had OB fold domains. The results also showed that both AS and SNV caused gene polymorphism was positively correlated with gene expression, and most OBGs in HCC had SNV phenomenon, but not occurred in healthy liver tissue.Conclusion Collectively, AS and SNV may be important regulatory factors for gene expression. SNV may particularly affect the function of OBGs in the MCM complex to abnormally initiate DNA replication in HCC.
