Objective To establish a histological classification system for osteophytes by Masson staining and immunohistochemical staining for collagen type II. Methods Osteophytes were collected from knee joints in os?teoarthritis patients after joint replacement surgery. To develop an osteophyte classification ,serial tissue sections were identified using histological(hematoxylin and eosin,Masson ' s trichrome,toluidine blue)and immunohisto?chemical staining(collagen typeⅡ). Joint function was assessed by WOMAC score and radiological findings was measured by Kellgren?Lawrence grading. The consistency between the osteophyte classification and WOMAC/Kell?gren?Lawrence grading were evaluated. Results 31 patients and 101 osteophyte samples were included in this study. Based on the histological and immunohistochemical evaluation,osteophytes can be divided into type A (4.9%),type B(4.0%),type C(26.7%)and type D(64.4%). This histological classification system had better consistency with joint function score(χ2 = 0.108,P = 0.947)and Kellgren?Lawrence grading(χ2 = 3.205,P =0.201). Conclusions This trial establishes a histological classification system for osteoarthritis osteophytes ,types A and B indicating early osteophyte and types C and D indicating advanced osteophyte. The system is helpful in clini?cal and basic research on osteoarthritis.

OBJECTIVETo investigate the effects of prostate stromal cells from different zones of normal prostate tissue on the growth of prostate cancer cells and their action mechanisms.

METHODSWe extracted stromal cells in the fresh normal prostatic tissue derived from the peripheral zone (PZ) or transitional zone (TZ), amplified them in vitro, and used the supernatants of the cells as conditioned media to culture hormone-resistant prostate cancer DU145 cells. We measured the growth curve of the tumor cells using the CCK8 method, determined the number and viability of the cells by trypan blue staining, evaluated their invasiveness by scratch test, and detected the effects of the stromal cells on the key enzymes in the glycolysis of the tumor cells by Western blot.

RESULTSThe conditioned medium with the PZ-derived stromal cells promoted, while that with the TZ-derived stromal cells inhibited the growth of the tumor cells. The former significantly increased, while the latter markedly decreased the expressions of the key enzymes hexokinase 2 (HK-2), pyruvate kinase 2 (PKM-2), lactate dehydrogenase (LDHA), and pyruvate dehydrogenase (PDH) in the glycolysis of the tumor cells.

CONCLUSIONProstate stromal cells from different zones exert different influences on the growth of tumor cells, which may be associated with their different effects on the glycolysis of tumor cells.

Objective:To study the effect of naoxintong capsules combined with nerve growth factor on the serum levels of interleukin-6 (IL-6),matrix metalloproteinase-9 (MMP-9) and S100B of patients with hypertensive intracerebral hemorrhage.Methods:88 patients with hypertensive intracerebral hemorrhage who were treated in our hospital from August 2015 to July 2016 were selected and randomly divided into the observation group and the control group The patients in the control group were treated with nerve growth factor,while the patients in the observation group were treated with naoxintong capsules combined with nerve growth factor.Then the clinical efficacy,GCS,GOS score,serum levels ofIL-6,MMP-9 and S100B were observed and compared between the two groups.Results:After treatment,the total effective rate in the observation group was significantly higher than that the control group (P＜0.05).After treatment,the GCS and GOS scores of the two groups were significantly higher than before,and the GCS and GOS of the observation group were higher than those of the control group (P＜0.05).After treatment,the serum levels of IL-6,MMP-9 and S100B in the two groups were significantly lower than before,and the observation group were lower than those of the control group (P＜0.05).There was adverse reactions in the two groups.Conclusion:Naoxintong capsule combined with nerve growth factor can reduce the serum levels of IL-6,MMP-9 and S100B in patients with hypertensive intracerebral hemorrhage,with obvious clinical curative effect and high safety.

Objective To explore the therapeutic effects of early short time venous-venous hemofiltration(SVVH) on severe acute pancreatitis(SAP) with acute lung injury(ALI).Methods Twenty-there patients with SAP and ALI were treated by routine project,and among them twelve patients accepted SVVH therapy.During the therapy,life sign、PaO2/FiO2 and APACHEII score were registered.Results Compared with control group,the clinical representation and organ function of SVVH group meliorated. PaO2/FiO2 were raised, APACHEII score and death risk were declined.Conclusions The early short time venous-venous hemofiltration(SVVH) on severe acute pancreatitis(SAP) with acute lung injury(ALI) could improve clinical symptom ,protect the organ dysfunction and decline the death risk.

Objective:To investigate the local application of exogenous VEGF on survival of rats random flaps after radiotherapy.Methods:45 four-month old Wistar rats were taken as experimental objects and divided into 3 groups randomly to construct animal models of random flaps and simulated radiotherapy with 60Co radioactive source with 6 Gy,500 cGy/min.All the rats were killed 28 days after radiotherapy were carried out.The vitality of flaps was observed 7 days and 28 days after radiotherapy.Flaps were evaluated with cytological staining experiments,histopathological experiments and SDH measurements.Results:The group which applied VEGF was greatly distinguished from control groups(P

Objective To probe into nursing management methods of replantation of amputated finger patients accepting brachial plexus block analgesia and patient-controlled sedation (PCS) after operation.Methods 48 patients of replantation of amputated fingers accept continuous brachial plexus block analgesia and PCS after operation,Analgesia was 0.2% ropivaeaine,sedation was 0.05% midazolam or compositive liquid mixed 0.05% midazolam and 0.0005% fentanyl,the visual analogue scale (VAS),sedation scores and the changes of vital signs and side effocts after operation were recorded before the operation and at time intervals of 6,12,24,48,72 hours after the operation.Results The visual analogue scale(VAS)in the post-operation was obviously lower than the pre-operation,the Ramsay scores of PCS were higher than the pro-operation.There was no inadequate or excessive sedation.No influence was seen on respiration,circulation system and no other side effects happened.Conclusions Brachial plexus block analgesia and patient-controlled sedation (PCS) can offer a good Analgesia and sedation effect for patients of amputated fingers replantation,in period of analgesia and sedation,we should strengthen nursing and monitoring of vital signs to avoid accident.

Objective: To explore the burden of spouse caregivers of patients with dementia at home and factors having influence.Methods:Forty-two patients with dementia were collected from psychiatric out-clinic consecutively. Trained investigators did home visit to collect data on severity of the disease (CDR, MMSE), pathological behavior (BEHAVE-AD), activity of daily living (ADCS-ADL) and burdens of their spouse as caregiver (CBI). The caregivers' anxiety, depression (Zung's Anxiety Scale and Depression Scale) and knowledge about dementia were also collected.Results:The caregivers felt big burden (BDI total score: 30.7?15.1). Nearly half of them (42.9%) were in depression and one quarter (23.8%) were anxious. They were lack of knowledge about dementia and unskillful in care-giving. 26.2% caregivers thought dementia is curable or equal to normal aging, 57.1% of them did not believe it is an improving disease. The burden of caregivers was correlated positively with pathological behavior of patients (r=0.40, P
