Objective To investigate the imaging appearances of non-ossifying fibromas in healing stage and its clinical value.Methods The imaging features of non-ossifying fibroma in healing stage in 10 cases followed-up clinically(2 cases of them were verified by pathology after operation) were analyzed. All of the cases were examined by radiography,4 cases were examined by CT, 1 case underwent MRI. Results All of the cases were located in long bone of lower extremity. 8 cases were in tibia,2 cases were in femur. 5 cases were shown as homogeneous sclerosis,lucent areas were presented in sclerotic foci in 5 cases. 5 cases were unchangeable after followed-up 1 to 4 years .Conclusion The non-ossifying fibroma is being sclerotic stabilized foci after puberty , no operation is necessary for the healed form non-ossifying fibroma.

Objective To explore the prognostic value of the content of lentil lectin-reactive alphafetoprotein-L3(AFP-L3)in early-stage hepatocellular carcinoma(HCC).Methods According to the content of alpha.fetoprotein(AFP)and AFP-L3 before the treatment,97 patients with early-stage HCC were divided into group A(AFP＞20 μg/L & AFP-L3＜15%,n=29),group B(15%≤AFP-13≤50% & 20 μg/L≤AFP≤200 μg/L,n=16),group C(AFP-13＞50%& AFP＞200 μg/L,n=13),group D(AFP-L3＞50% & 20 μg/L≤AFP≤200 μg/L,n=24)and group E(15%≤AFP-L3≤50%& AFP＞200 μg/L,n=15).The degree of tumor differentiation,the 1-,2-,3-year survival rates and tumor-free survival rates of the patients were analyzed.Results The degree of tumor differentiation.3-year survival rate and tumor-free survival rate of patients in group A were significantly higher than those in the other 4 groups(χ2=21.051,10.043,4.450,6.977,25.566,P＜0.05).The degree of tumor differentiation,1-,2-,3-year survival rates and tumor-free survival rates of the patients in group C and D were significantly lower than those in other 3 groups(χ2=7.938,3.488,9.085.P＜0.05).Conclusions The increase of AFP-L3 content is closely related to poorly differentiated HCC and bad prognosis.especially when the AFP Ievel is low.The detection of AFP-L3 content before and after operation is beneficial to the evaluation of the prognosis of HCC patients.

OBJECTIVETo study the syndrome of inappropriate ADH secretion (SIADH) after allogeneic hematopoietic stem cell transplantation (allo-HSCT) and the possible etiology.

METHODSThe clinical manifestation, laboratory examination, treatment and outcome of a patient with refractory anemia with excess blasts after allo-HSCT were presented.

RESULTSHyperacute graft-versus-host disease (GVHD) was developed in the patient after allo-HSCT followed by severe hyponatraemia (lowest serum sodium 103.7 mmol/L), natriuresis, hypo-osmolality of plasma, hyper-osmolality of urine, coma and twitch at day 17 after allo-HSCT. SIADH was diagnosed. The clinical condition was improved after restriction of water and administration of hypertonic saline, but SIADH was not controlled completely. Afterwards, graft failure was developed. Hyperacute GVHD and graft rejection occurred again after the second transplant. The patient died of secondary infection.

CONCLUSIONSIADH after allo-HSCT is a rare fatal acute complication of central nervous system. Numerous transplant-related causes are probably associated with the development of SIADH. Early accurate diagnosis and treatment promptly is of great importance.

Objective To investigate the effect of electroacupuncture on the expressions of in-terleukin(IL)-33 and ST2 in spinal cord and dorsal root ganglion in rats with neuropathic pain. Methods Forty adult female SD rats were randomly divided into sham operation group (group Sham),model group (group MC),ipsilateral electroacupuncture group (group SE)and contralateral electroacupuncture group (group VE).Each group had 10.The sciatic nerve injury models were es-tablished.The rats in group SE and group VE were respectively accepted electrical acupuncture treat-ment in Yanglingquan and Zusanli in the right and left limbs.Respectively,before treatment (T0 ), treated for 7 d (T1 ),3 d (T2 )and 7 d (T3 )after treatment,the MWT and TWL of rats in the four groups were measured.At T3 ,the expressions of IL-33 in spinal cord and dorsal root ganglion in rats were detected by using quantitative PCR.Results Compared with T0 ,MWT and TWL in group MC, group SE and group VE at T1-T3 were decreased significantly (P < 0.05).Compared with sham group,MWT in group SE and group VE,TWL in group MC,group SE and group VE at T1-T3 were decreased significantly (P <0.05).Compared with group MC,MWT and TWL in group SE and group VE at T2 ,T3 were increased significantly (P <0.05).Compared with sham group,the relative expression levels of IL-33 mRNA and ST2 mRNA in spinal cord and dorsal root ganglion in the group MC,group SE and group VE were elevated,the differences were statistically significant (P <0.05). Compared with group MC,the relative expression levels of IL-33 mRNA and ST2 mRNA in spinal cord and dorsal root ganglion group SE and group VE were decreased,the differences were statistical-ly significant (P <0.05).Conclusion The electroacupuncture treatment could significantly reduce the pain symptoms of neuropathic pain in rats,possibly via inhibiting the expressions of IL-33 and ST2 in spinal cord and dorsal root ganglion and blocking the IL-33/ST2 mediated inflammatory to play role.

OBJECTIVETo evaluate the functional outcomes of modified limited "L" incision beside the Achilles tendon with distraction bone block arthrodesis in treatment of subtalar osteoarthritis.

METHODSFrom March 2009 to September 2012, a total of 22 cases of old calcaneus fractures with subtalar osteoarthritis were treated with modified limited "L" incision and distraction bone block arthrodesis including 13 males and 9 females with a mean age of 35.3 years old (ranged 22 to 49). The mean time from calcaneal fracture was 21 months (ranged 11 to 32). According to the Stephens-Sanders classification, 16 cases were type II and 6 were type III. The modified-AOFAS ankle-hindfoot score was used for functional outcomes evaluation.

RESULTSThere was one incision necrosis and no infection, implant failure, bone-graft absorbed or talus necrosis was note at the follow-up time. A total of 21 cases were followed up for a mean time of 29 months (ranged from 18 to 46 months). All of the cases reached a bony union within 4 months postoperation. The mean modified-AOFAS ankle-hindfoot score was 82.6 points (ranged from 66 to 92 points),reached a significantly improvement in comparing with the mean preoperative score (50.8 points,ranged from 32 to 65 points, P < 0.01).

CONCLUSIONThe modified limited"L" incision beside the Achilles tendon with distraction bone block arthrodesis is an acceptable and alternative treatment method for subtalar osteoarthritis. This method is easy to use and with less complication. It can correct the main pathological changes and reach good functional outcomes.

Objective To explore the mechanism of anti-tumor effects of transferring tumor-specif-ic lymphocytes obtained from pre-immunized BALB/c mice with inactive rolL-21 tumor vaccine (mIL-21-Sp2/0)to syngeneic mice, associated with mIL-21 tumor vaccine immunization, in the condition of cyclo-phosphamide (Cy)-induced lymphopenia. Methods Activated lymphocytes of spleen and lymph nodes ob-tained from pre-immunlzed syngeneic mice with irradiated mIL-21-Sp2/0 cells were infused into BALB/cmice treated with Cy 2 days before, subsequently vaccinated with mlL-21 tumor vaccine, after 7 days, chal-lenged with Sp2/0 tumor cells, observed the growth of tumor of mice. T lymphocyte subsets differentiation was measured by flow cytometry (FCM) analysis. The proliferation and cytotoxie activities of activated lym-phocytes were analyzed by FCM, respectively, staining with CFSE and 7-AAD. The number of IFN-γ-secre-ting cells was evaluated by ELISPOT. Results The lymphopenic mice were transferred with activated lym-phocytes and inoculated with raiL-21 tumor vaccine might provide superior anti-tumor immunoprotection, re-tard tumor growth of the mice. The proliferating capabilities and killing rate of transferred tumor Ag-specific lymphocytes enhanced obviously, the number of IFN-γ-secreting cells was significantly higher compared with the control groups. Conclusion Under Cy-induced lymphopenia condition, tumor Ag-specific lymphocytes sensitized by raiL-21 tumor vaccine were transferred to mice and immunized with mlL-21 tumor vaccine at the same time, benefit the proliferation of transferred effective cells and immune cells itself, assist to form and sustain special anti-tumor effects.
