In recent years, the systematic treatment of liver cancer has made significant progress, but surgical resection remains as main treatment to obtain long-term survival for patients with liver cancer. With the rapid development of liver surgery, the complexity of liver anatomy and surgical operation are no longer the main obstacles to liver surgery. The insufficient future liver remnant (FLR) after hepatectomy has become the main limit of liver surgery. In clinical practice, most patients with liver cancer cannot undergo one-stage radical resection and can only receive non-surgical treatment, with poor long-term prognosis. The associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) provides hope for the treatment of liver cancer patients with insufficient FLR. ALPPS can induce significant hypotrophy of the FLR in a short period of time, and the radical tumor resection rate is as high as 90% to 100%, which significantly improves the prognosis of patients. However, in the early stages of the practice, there were considerable controversies on the safety of the operation. In recent years, with the continuous advancement of technology, the safety of ALPPS has been greatly improved. The authors synthesize the latest literatures and elaborate on the latest progress of ALPPS.

Objective To study the therapeutic effect of Fe3O4 nanometer magnetic fluid-induced hyperthermia on implanted liver cancer in nude mice under alternating magnetic field. Methods Nude mice model bearing implanted HepG2 was established. Mice were then randomly divided into 3 groups: the blank control group; the magnetic field group; nanometer magnetic fluid group. The magnetic field group were just put under the magnetic field; Nanometer magnetic fluid group received injection of PEG-PEI/Fe3O4 nanometer magnetic fluid under the alternating magnetic field. At the frequency of 40 kHz, and magnetic field of 5 kA/m, 15 minutes one day in the next 14 days. On the 7th day and the 15th day, the changes of tumor volume and weight were recorded, cell apoptosis were observed and recorded and pathological examination was done. Results On the 7th and the 15th day, in the nanometer magnetic fluid group, tumors' volume was smaller and the weight was lighter than other groups, and the tumor inhibitory rate of 54. 20% (t = 14. 506,P ＜0. 01 ) was significantly higher than the control group and the magnetic field group 22. 66% ( t = 7.497, P ＜ 0. 05 ). In the control group, tumor cells grew well, high density, the nucleus engrained, the shape irregular, the nuclear fission clear; compared with the control group, in the magnetic field group, tumor cells scatter thinly, intercellular substance increases, and necrosis area formed;in the nanometer magnetic fluid group, many of tumor cells died, their cell nucleus broke up and vanished,the blood vessel reduced obviously, and the tumor cell spread thinly. Conclusions Under the alternating magnetic field, PEG-PEI/Fe3O4 nanometer magnetic fluid inhibits liver cancer growth in nude mice model of HepG2.

The construction of featured specialties is the current development strategy of community health service institutions to improve the service scope and to meet the health needs of residents. The rehabilitation medicine has undergone 12 years of development and become a relatively mature featured specialty in Fenglin Community Health Service Center. Based on the Fenglin′s experience, this article discusses the development status and restriction bottlenecks of general practice, and the development status and trend of rehabilitation medicine in the community; and also explores the integrated development model of community-featured specialty with general practice.

Community health institutions have entered a new development stage of featured specialty construction. After 12 years of development, rehabilitation medicine now is the featured specialty of Fenglin Community Health Service Center. This article presents the train of thought and key points of specialty construction in primary care institutions based on the Fenglin′s experience. The positioning of featured specialty should be based on the community. The construction process should include 7 elements, namely, the standard operation procedure(SOP)of service system construction, the detailed publicity and implementation of the collaboration of specialists, prevention and control knowledge promotion for general practitioners, prevention and control knowledge education for community residents, service list, clinical efficacy evaluation, and clinical database. In the later iterations, the head of the department should always focus on the service system construction SOP and clinical database construction, and the rest parts can be assigned to the relevant team members.

Objective: To investigate the pathogen spectrum distribution and drug resistance of febrile neutropenic patients with hematological diseases in Shanghai. Methods: A retrospective study was conducted on the clinical isolates from the febrile neutropenic patients hospitalized in the departments of hematology in 12 general hospitals in Shanghai from January 2012 to December 2014. The drug susceptibility test was carried out by Kirby-Bauer method. WHONET 5.6 software was used to analyze pathogenic bacteria and drug susceptibility data. Results: A total of 1 260 clinical isolates were collected from the febrile neutropenic patients. Gram-positive bacteria accounted for 33.3% and Gram-negative bacteria accounted for 66.7%. Klebsiella pneumoniae (12.5%) , Stenotrophomonas maltophilia (9.5%) , Escherichia coli (9.1%) , Pseudomonas aeruginosa (8.7%) , Acinetobacter baumannii (6.6%) , Staphylococcus aureus (5.6%) and Enterococcus faecium (5.0%) were ranked in the first 7 of all pathogens. In the respiratory tract secretions specimens, non-fermented strains accounted for 56.2%. Stenotrophomonas maltophilia accounted for 15.2%. Enterobacteriaceae and coagulase-negative Staphylococci accounted for 42.3% (104/246) and 32.6% (85/246) respectively in blood samples. Enterobacteriaceae and Enterococcus bacteria accounted for 39.4% (76/193) and 28.5% (55/193) respectively in pus specimens. The detection rates of methicillin resistant Staphylococcus aureus (MRSA) and methicillin resistant coagulase negative Staphylococci (MRCNS) were 54.3% and 82.5%, respectively. Staphylococcus bacterial strain was not found to be resistant to linezolid, vancomycin and teicoplanin. The detection rate of Enterococcus vancomycin-resistant strains was 8.9%. Enterococcus was not detected resistance to oxazolidinone strains. Enterobacteriaceae bacteria were highly sensitive to carbapenems. The resistance rate of Pseudomonas aeruginosa to imipenem and meropenem was 34.1% and 15.8%, respectively. Stenotrophomonas maltophilia was more sensitive to minocycline hydrochloride, levofloxacin and sulfamethoxazole. The resistance rate of Acinetobacter baumannii only to cefoperazone-sulbactam was less than 10.0%. The antibiotic resistance rate of Klebsiella pneumoniae, Stenotrophomonas maltophilia, Pseudomonas aeruginosa and Acinetobacter baumanii to most of common antibiotics was lower than that of the CHINET surveillance. Conclusions The pathogenic strain distribution in common infection sites of febrile neutropenic patients was characterized. Bacterial resistance surveillance was better than the CHINET nationwide large sample surveillance in China.
