AIM To observe the effects of Guhoukang Granules (Eucommiae Cortex,Dipsaci Radix,Corni Fructus,etc.) on bone metabolism indexes of the geriatric femoral intertrochanteric fracture.METHODS A total of eighty patients meeting the inclusion criteria,cured with fixed operation of proximal femoral anti-rotation nail and given basic care,were divided randomly and equally into two groups:experiment group (Guhoukang Granules ) and control group (calcium carbonate D3 tablets).Three months made a course.Osteocalcin (OC),calcitonin (CT),bone-specific alkaline phosphatase (BALP),total procollagen type 1 aminoterminal propeptide (tPINP),β isomer of the C-terminal telopeptide of type Ⅰ collagen (β-CTX),and intact parathyroid hormone (iPTH),were examined before and after three months,respectively.RESULTS There were no significant statistical difference in the levels of OC,CT,BALP,tPINP,β-CTX and iPTH before operation in both groups.The levels of OC,CT,BALP,tPINP in the experiment group obviously increased and the levels of β-CTX,iPTH markedly decreased after the operation,and were better than those in the experiment group pre-operation and in the control group after the operation.The control group had no improvement in bone metabolism indexes pre-and post-operation.CONCLUSION Guhoukang Granules can improve bone metabolism of the geriatric femoral intertrochanteric fracture and facilitate the recovery of the fracture.

Objective To explore the effect of psychological resilience and mood on mental health of leftbehind children.Methods Positive and Negative Affect schedule (PANAS),the Resilience Scale for Chinese Adolescent (RSCA) and Mental Health Scale of Middle School Student (MSSMHS) were administrated to 796 left-behind children.Results ①Positive/negative emotions could significantly predict psychological resilience (β=0.875,P＜0.01 ; β=-0.713,P＜0.01).②Psychological resilience had significantly negatively forecast mental health (β=-0.759,P＜0.01).③The relationship between negative affect and mental health was partially mediated by psychological resilience (P＜0.01).The relationship between positive affect and mental health was completely mediated by psychological resilience.Conclusion Psychological resilience plays an important role in the relationship between positive/negative emotions and mental health.Positive affect can improve mental health of left-behind children through psychological resilience.

Objective To analyze the space-time characteristics of hand-foot-mouth disease (HFMD) in Shijiazhuang by using geographic information system (GIS).Methods The data of HFMD during 2009 to 2011 in Shijiazhuang were collected and GIS database was created.Special map was drawn by PHGIS software to analyze the space-time characteristics of HFMD in Shijiazhuang.Results The epidemic situation of HFMD in Shijiazhuang appeared sporadic with local centralization.The attack ranked alternately rise year after year and high epidemic areas were geographically complimentary.Overall epidemic levels tend dropping from 2009 to 2011 and there were differences among areas.The high-attack areas of HFMD changed over time.Conclusions GIS can provide direct-viewing of the space-time characteristics of HFMD and further understand the prevalence of HFMD,which could help to provide the scientific basis of HFMD control in Shijiazhuang.

Objective To use clustering analysis to help physicians detect abnormal parameters in radiotherapy treatment plans and improve the efficiency of plan verification. Methods From 2010 to 2015, 835 breast cancer treatment plans for using 4?field hybrid intensity?modulated radiotherapy from MOSAIQ were collectted. Fractional dose, beam angle, and monitor unit were used as featured parameters of a treatment plan to generate a dataset. The K?means clustering algorithm based on principal component analysis was used to perform a clustering analysis of the dataset and divide the dataset into different clusters. The outliers of clusters were automatically detected based on the distance threshold. The outlier?contained treatment plans were manually verified by physicians to determine the accuracy of clustering analysis in detection of abnormal plans. Results In the clustering analysis, the sample space composed by parameters of treatment plans for breast cancer was divided into 4 clusters, 3 of which had outliers detected. In the targeted treatment plans, 3 plans became outliers because of special target volume and the other 4 plans needed improvement. Conclusions Clustering analysis is effective to help physicians to independently verify treatment plans.

Numbers of nerve cells in CA1 and CA3 area were calculated under the microscope to calculate the density of nerve cell.MAIN OUTCOME MEASURES: ① Density of nerve cell in cerebral hippocampus of mice in each group; ② Ultrastructure of nerve cell in cerebral hippocamp us of mice in each group.RESULTS: Totally 30 mice entered the final analysis. ① Density of nerve cell in hippocampal CA1 and CA3 area of brain: Density in zishen prescription group and vitamin E group was higher than that in control group [CA1: (3 707±495), (3 812±281), (257±372) mm-2; CA3:(2 746±262),(2 397±366), (1 992±307) mm-2, t=2.68-8.30, P ＜ 0.05-0.01]. ② Aging of mitochondrion was decreased, deposition of lipofuscin and aging of lysosome in cytoplasm were reduced in zishen prescription group and vitamin E group.CONCLUSION: Granule of nourishing kidney and tonifying brain can defer density decrease of nerve cell and aging of cell in hippocampla area of mice' brain.

Objective To investigate the clinical characteristics of alcoholic severe acute pancreatitis (SAP). Methods Clinical data of 166 cases of SAP in Fujian Provincial Hospital from January 2001 to December 2008 were collected and analyzed retrospectively. Cases were divided into alcoholic SAP group (43cases) and control group ( 123 cases) depending on deoholic intake volue whithin 12～48 hours. Age, gender,CT scores, APACHE Ⅱ score, serum glucose, serum triglyceride (TG), serum calcium, serum albumin,morbidity, later infection rate and mortality rate of the two groups were compared. Results There was no significant difference in terms of age, but the proportion of male in alcoholic SAP group (39/43) was higher than that in control group (58/123, P<0.01 ). CT score, serum glucose and calcium were not significantly different between the two groups. The APACHEⅡ score and serum TG in alcoholic SAP group [19.16±5.38,(5.06±4.03)mmol/L] were significantly higher than those in control group [16.02±5.09, (3.12±2.95)mmol/L]. The albumenjolevel in alcoholic SAP group (25.23±7.12)g/L) was lower than that in control group [(30.68±8.35 ) g/L, P<0.01]. The incidences of ARDS and upper gastroenterologic bleeding were not significantly different between the two groups. But the incidences of acute kidney failure (44.2%), liver failure (41.9%), heart failure (37.2%), shock (39.5%), infection (27.9%) and mortality (30.2%) in alcoholic SAP were significantly higher than those in control group (26.0%,30.9%, 20.3%, 16.3%,16.3%, 7.3%, P<0.05 or<0.01). Conclusions Males predominates alcoholic SAP patients with high mortality and morbidity. Alcohol abstinence is effective to prevent alcoholic SAP ocurrence.

ObjectiveTo investigate the effects of Yinhuang solution on the bladder mucosal before and/or after mucosal injury.Methods32 SPF female SD rats were randomly divided into 4 groups with 8 rats in each group. Group A was used for the normal control group, group B for the model control group, group C for preventive group, group D for preventive and therapeutic group. Injured rats were created by hydrochloric acid applied on bladder mucosa. After the models were established or before and after the models were established, bladders were perused with Yinhuang solution. Severity of inflammatory infiltration were observed by HE staining, histological score and heat shock protein 70 (HSP70) expressed in the mucosa.ResultsEndoscopic pathological change showed that group B had a large number of inflammatory cell infiltration, significant expansion of capillary, epithelial cell necrosis. Group C had a small amount of expansion of capillary, inflammatory cell infiltration. Group D scattered in expansion of capillary, a small amount of inflammatory cell infiltration. Concerning the results of histological score and HSP70 expression, there was a significant difference between group A and groups B, C or D (P<0.01); there was a significant difference between group B and groups C or D (P<0.01); there was a significant difference between group C and group D (P<0.05).ConclusionYinhuang solution can evidently improve the repair capability of bladder mucosa after injury.

BACKGROUND: As a micro-injurying and reduplicative treatment of osteoarthritis,the arthroscopic debridement has got the affirmation of numerous scholars. But as one of the standard procedures in artnroscopic debridement,synovectomy is called in question recently.OBJECTIVE: To explore the applied value of synovectomy in the arthroscopic debridement of osteoarthritis.DESIGN: Retrospective controlled analysis.SETTING: Department of Orthopaedics, Fushun Central Hospital.PARTICIPANTS: Sixty-five patients received synovectomy in the arthroscopic debridement of knee joint osteoarthritis in the Department of Orthopaedics,Fushun Central Hospital from February 1997 to December 2000.Thirty-two among them,with complete data and over 1 year's followup,were taken for synovectomy group. Forty-eight patients received the arthroscopic debridement of knee joint osteoarthritis without synovectomy in the Department of Orthopaedics,Fushun Central Hospital from January 2001 to November 2003.Thirty among them,with complete data and over 1 year's follow-up,were taken for control group.METHODS: Synovectomy was taken as the factor of intervention in the operation to perform grouping. The analysis of curative effect was performed to control with joint douching,corpus liberum removal,osteophyma cleaning,meniscus fitting,cartilage gouging,synovectomy and without synovectomy or part synovectomy. Lysholm evaluation standard of knee joint osteoarthritis was used to the knee joint functional evaluation beween preoperation and postoperative 1 year in two groups. And operative time,postoperative draining quantity,postoperative 7-day visual analog score,postoperative 1-year Lysholm score of knee joint, were recorded.MAIN OUTCOME MEASURES: Preoperative and postoperative 1-year Lysholm score of knee joint,operative time,postoperative draining quantity,postoperative 7-day visual analog score.RESULTS: Sixty-two patients were included and all of them entered the result analysis.The preoperative patients in two groups were comparable with each other and the differences of Lysholm score were not significant (t=0.127,P=0.899).The operative time was longer in synovectomy group than in control group,the differences were significant (t=9.547,P ＜ 0.001)and the postoperative draining quantity was more in synovectomy group.The postoperative visual analog score was bigger in synovectomy group than in control group and the differences were significant [the scores of synovectomy and control groups were respectively (4.6±1.1),(2.8±1.4),t=6.206,P ＜ 0.001].The differences of knee joint score in 1-year follow-up were not significant [the scores of synovectomy and control groups were respectively (77.6±11.9),(79.0± 10.3),t=0.562,P=0.576].CONCLUSION: Synovectomy can not increase the curative effect in the near future in the arthroscopic debridement of osteoarthritis. On the contrary,the operative time was longer,the operative wound was larger and postoperative reaction was more serious. It should not be used in the debridement generally.
