BACKGROUND:Studies have shown that bone loss can lead to a series of diseases, such as osteoporotic fractures, thus seeking to increase bone mass has become a goal of the majority of researchers.
OBJECTIVE:To summarize the current studies of improving bone mass by using stem cel transplantation, hoping to the extensive application of stem cel transplantation in the clinical treatment of osteoporosis as early as possible.
METHODS:A computer-based search of PubMed and CNKI was performed by the first author to retrieve articles relevant to stem cel therapy for osteoporosis published from January 1997 to October 2014. The keywords were“to improve bone mass, regenerative medicine, bone marrow mesenchymal stem cel transplantation, stem cel therapy”in Chinese and English, respectively, which appeared in the title, abstract or keywords. Articles published recently or in authoritative journals were preferred, and final y 28 articles were included in result analysis.
RESULTS AND CONCLUSION:Bone marrow mesenchymal stem cel s which are isolated and cultured easily can proliferate rapidly and have multi-lineage differentiation potential. Studies have shown that the osteogenic differentiation of bone marrow mesenchymal stem cel s can real y improve bone mass, and obtain more achievements in the treatment of orthopedic disorders. This new cel therapy can help to accelerate bone healing and reduce treatment time, offering a new therapeutic choice for orthopedic surgery, plastic surgery, oral and maxil ofacial surgery, and therefore, it has broad application prospects.

ObjectiveThe trial was to examining the effectiveness and cost effects of family intervention for rehabilitating chronic outpatients with schizophrenia in the country.Methods90 subjects were randomly assigned to the family intervention group and the control group. Both groups received the same treatments, but the family intervention courses mainly containing mental health education were given to the family intervention group for one year. During the time, all subjects were evaluated with standard rating scales and self made criteria. ResultsThe family intervention group demonstrated clinical results significantly superior to those of the control group on overall improvement according to the scores on the SDSS, the SAPS, the SANS and the MRSS. Substantially, the direct and indirect average cost in the family intervention group was significantly lower than those of the control group. Conclusions Family intervention is effective not only in making the schizophrenics recover from illness but also in both increasing their social functions and reducing their medical cost.

ObjectiveTo evaluate the clinical outcome of new proximal femoral nail antirotation (PFNA) in treatment of subtrochanteric fractures. MethodsThere were 31 patients with traumatic subtrochanteric fractures intramedullarily fixed with PFNA. The patients included 14 males and 17 fe-males at a mean age of 54.6 years (range 34-90 years). According to Seinsheimer classification of sub-trochanteric fractures, 14 patients were with type Ⅱ fractures (including four patients with type ⅡA,seven with type ⅡB and three with type ⅡC), 12 with type Ⅲ fractures (including eight with type ⅢA and four with type ⅢB), two with type Ⅳ fractures and three with type Ⅴ fractures. Close reduction was performed under traction and C-arm fluoroscopy in 26 patients and open reduction through a mini-incision before inserting the nail in five patients due to difficult close reduction. ResultsThe operation lasted for a mean time of 72.5 minutes (range 45-120 minutes), with mean blood loss of 127.5 ml (range 100-350 ml). Of all, 27 patients (87.1%, 27/31) were followed up for a mean duration of 14.3 months (range 8-24 months), which showed fracture union in all patients, with a mean union period of 17.4 weeks (range 10-21 weeks). According to Harris Hip Rate Scale, the results were. excellent in 21 pa-tients, good in two and fair in four, with excellence rate of 85.2% (23/27). ConclusionsPFNA is an effective device for treatment of subtrochanteric fracture, with a high union rate and a low complication rate, for it has advantages of easy use and minor trauma, low bleeding and stable fixation in operation.

Objective: To explore the possible mechanism of Duhuo Jisheng Tang in relieving knee osteoarthritis based on protein kinase R-like endoplasmic reticulum kinase (PERK)/immunoglobulin-binding protein (Bip) signaling pathway.Method: A model of knee osteoarthritis was established by cold stimulation.Rats were randomly divided into blank group,model group,celecoxib group (0.021 g·kg^-1),low,medium and high-dose Duhuo Jisheng Tang groups (8.37,16.72,33.48 g·kg^-1).Blank group and model group were given equal volume of physiological saline.The changes of knee joint diameter were recorded.The pathological changes of rat articular cartilage were observed by hematoxylin-eosin (HE) staining.The expressions of tumor necrosis factor-alpha (TNF-α),interleukin-1β(IL-1β) and hyaluronic acid (HA) in serum were detected by enzyme-linked immunosorbent assay (ELISA).The mRNA and protein expression levels of PERK,Bip and cysteinyl as parates pecific protein-9(Caspase-9) in cartilage were detected by Real-time PCR and Western blot.Result: The knee joint redn ess and the joint diameter of celecoxib group and high-dose Duhuo Jisheng Tang group were improved,and the joint diameter was reduced significantly (P<0.01).The local fractures of knee joint cartilage in the celecoxib group and the high-dose Duhuo Jisheng Tang group were significantly improved.Compared with blank group,the expression levels of TNF-α,IL-1β and HA were increased in model group (P<0.01).The gene and protein expression levels of PERK,Bip and Caspase-9 in cartilage of the model group were increased (P<0.05,P<0.01).Compared with model group,the expressions of TNF-α,IL-1β and HA in serum of celecoxib group and high-dose Duhuo Jisheng Tang group were decreased (P<0.05,P<0.01).The mRNA and protein expression levels of PERK,Bip and Caspase-9 in cartilage of celecoxib group and high-dose Duhuo Jisheng Tang group were decreased (P<0.05,P<0.01).Conclusion: Duhuo Jisheng Tang can alleviate the symptoms of knee osteoarthritis model rats,and its mechanism may be related to the regulation of PERK/Bip signaling pathway in rat cartilage.

Objective:The objective of the study was systematically summarized the current status of the hepatocellular carcinoma (HCC) screening guidelines, and evaluated the HCC screening guidelines according to the authoritative framework of cancer screening guidelines of authoritative institutions, which provided important value for the formulation of HCC screening evidence-based guidelines.Methods:Literature search was conducted in multiple databases from their inception dates to January 3, 2019. In addition, we sought relevant websites further was searched to identify potentially eligible studies. Two reviewers independently screened literature and extracted data. Qualitative description of the basic information, recommendations of HCC screening, source of evidence and update progress of the HCC screening guidelines was conducted.Results:At present, there were no independent HCC screening guidelines worldwide. There were only 17 clinical practice HCC guidelines briefly provided the recommendation of HCC screening. Current HCC screening guidelines only recommended screening for high-risk groups of HCC. All guidelines have identified patients with chronic hepatitis B, hepatitis C and cirrhosis as high-risk groups for HCC. Most of guidelines recommended screening intervals was 6 months. The latest guidelines in Europe and the United States recommended ultrasound for screening HCC. The combination of ultrasound and AFP was recommended in the Asian guidelines. Currently, HCC screening guidelines mainly recommended screening strategies based on factors such as risk of HCC, accuracy of screening modality, screening cost, etc.. The key factors such as screening efficacy and safety have not yet been considered comprehensively. Conclusions:There were no independent HCC screening guidelines worldwide. Only some clinical practice HCC guidelines briefly mentioned HCC screening. Currently, the guidelines only recommend screening for high-risk groups of HCC, with a screening interval of 6 months. There are differences in screening modalities recommended by European, American and Asian guidelines for screening HCC. It is suggested that the relevant institutions should formulate the evidence-based HCC screening guidelines by referring to the theoretical framework of other authoritative other cancer screening guidelines.
