Tumor-derived heat shock protein-peptide complex 96 (HSPPC-96) containing tumor antigenic peptides can elicit po-tent tumor-specific and protective immunity. Autologous HSPPC-96 vaccine has been shown to effectively prolong recurrence-free sur-vival and increase the overall survival of many tumors, thereby suggesting extensive future applications. However, as an autologous tu-mor-derived individual vaccine, the development of HSPPC-96 vaccine is challenged by the lack of an adequate autologous tumor, lim-ited efficacy for advanced-stage cancer, etc. This paper summarized the progress, future perspectives, and challenges in the clinical de-velopment of HSPPC-96 vaccine immunotherapy.

Subclavian artery occlusion is a common peripheral artery occlusion disease of various causes,with incidence of 1.9％.The most common symptoms are dizziness,ataxia,and hemiplegia that are caused by subclavian steal syndrome.Surgery is the only therapeutic method for symptomatic patients.Open surgery remains an important role despite of the rapid progress in endovascular surgery.Main surgical method includes carotid-subclavian transposition (CST),carotid-subclavian bypass (CSB) and axillary-axillary bypass.Each one is suitable for different lesions and anatomies.Both the effectiveness and safety have been testified.

The purpose of this study is to investigate the effect of Tetramethylpyrazin (TMP) on blood volume (△Er) and Hb oxygen sufficiency(F) of gastric mueosal su. perficial microcirculation in rat by reflectance spectrophotometry, on the formation of stress ulcer and on gastric mucosal blood flow (GMBF) by H_2 gas clearance. The results showed that TMP had no visible effect on △Er and F of normal anethetized rat. In hemorrhagic shock rat, F of gastric mucosa was increased from 13?10 to 22?5 (P

AIM: To contrast the effect of small incision phacoemulsification and non-phacoemulsification to treat cataract.
METHODS: Totally 172 patients with cataract were divided into 2 groups ( n = 86 ) randomly. Patients in Group Phaco were treated with phacoemulsification and, while those in Group Siecs were treated with small incision extracapsular cataract surgery and intraocular lens implantation. They were all followed up for 1-3y. Functional examinations were made at 3d;1,6mo and last follow - up. The visual acuity, intraocular pressure, anterior chamber depth, average corneal power ( ACP ) , cylinder ( CYL ) , surface asymmetry index ( SAI ) and complications were contrasted between groups.
RESULTS: At 3d after operation, the visual acuity of Group Phaco was better than that of Group Siecs ( P<0-05), and CYL, SAI and intraocular pressure of Group Phaco were all significantly lower than those of Group Siecs (P<0. 05). At 1mo after operation, the visual acuity of Group Phaco was better than that of Group Siecs ( P<0-05), and CYL, SAI and intraocular pressure of Group Phaco were slightly lower than those of Group Siecs ( P<0. 05);there was no difference between the two group. At 6mo after operation, the visual acuity of Group Phaco was still better than that of Group Siecs (P<0. 05), and CYL, SAI and intraocular pressure of Group Phaco were flat as those of Group Siecs (P<0. 05); there was no difference between groups in those indexes above ( P > 0. 05 ). Furthermore, the APC and anterior chamber depth of each point- in - time had no significant difference between groups (P>0. 05). The incidences of complication were similar in two groups ( P> 0. 05 ); but with individual differences, patients of GradeII and Ⅲ in Group Phaco got lower complication rate (P<0. 05), while those of Grade Ⅳ higher (P<0. 05) than those of Group Siecs.
CONCLUSION: Our research shows that phacoemulsification has high effect in the treatment of patients with GradeII and Ⅲ nuclear hardness, while small incision extracapsular cataract surgery has high effect in the treatment of patients with Grade Ⅳ nuclear hardness.

Non-invasive coronary artery angiography is one of the hotspots of imaging.This article reviewed the status and the relevant advancement of the cardiac EBCT, DSCT, MSCT and MR imaging.

Objective To evaluate the value of color Doppler flow imaging(CDFI) in the diagonosis of placental site trophoblastic tumor(PSTT). Methods After being examined by transvaginal CDFI, four of six patients underwent curettage and two of them had hysterectomy and attached by chemical treatment. All the patients were verified to have a PSTT by pathology. Results The image of PSTT in CDFI included different size at different site, low resistence index (RI) of vessel around the lesion, and absence of vessel in the lesion. Conclusions The characteristic image in CDFI is helpful to the diagnosis of PSTT.

AIM: To observe the effect of thichosanthes injection on the expression of proliferating cell nuclear antigen (PCNA) of vascular smooth muscle cell (SMC). METHODS: The expression of PCNA of cultured rabbit aortic SMC was examined with LSAB immunohistochemical technique, and [ 3H]-thymidine([ 3H]-TdR) incorporation data of SMC and the contents of superoxide dismutase (SOD), lipid peroxide (LPO), prostacyclin (PGI 2) and cyclic AMP (cAMP) in medium were simultaneously determined. RESULTS: Thichosanthes injection has an effects of increasing SOD activity, decreasing LPO, elevating PGI 2 and cAMP, reducing [ 3H]-TdR incorporation and expression of PCNA (all P

Asymmetric dimethylarginine(ADMA)is an endogenous inhibitor of nitric oxide synthase(NOS).it reduces nitric oxide production. ADMA is correlated with the risk factors of atherosclerosis, such as hypercholesterolemia, hypertension and hyperglycaemia. Accumulating evidence suggests that a derangement of the NOS pathway plays a critical role in atherogenesis and ADMA may participate in the process.

To investigate the correlation between cerebral infarction and carotid atherosclerosis.Methods:Bilateral carotid atherosclerotic plaques,intima-media thickness (IMT),and stiffness coefficient (β) in 60 patients with cerebral infarction were detected by high-frequency color Doppler imaging,and they were compared with the control group (n=60).Results:The detection rate of plaque in the cerebral infarction group was significantly higher than that in the control group (90% vs 28%,P<0.005); the constituent ratio of soft plaques in the cerebral infarction group was significantly higher than that in the control group (P <0.01),and the constituent ratio of flat and hard plaques was significantly lower than that in the control group (P<0.005); IMT and β values in the cerebral infarction group were significantly higher than those in the control group (P<0.01).Furthermore,IMT had significant positive correlation with β values (P<0.01).Conclusions:Carotid atherosclerosis is closely correlated with cerebral infarction.

A total of 17 hip joint lesion patients (24 hips) combined with ankylosing spondylitis and severe osteoporosis from March 1996 to March 2003.They.received autologous impaction bone graft and cementless total hip replacement.They were 20-52 years old,averagely 35 years.Harris score and X-ray method were used to evaluate clinical outcomes.A total of 17 patients (24 hips) were followed up for 36-120 months,averagely 87 months.Harris score increased from averagely 34 points (preoperation) to averagely 86.4 points (postoperation),resulting in an excellent and good rate of 87.5%.Radiograph showed that femoral prosthesis was closely fixed to proximal segment of the femur,without prosthetic infection or dislocation.One hip suffered from 5-mm prosthetic subsidence within 1 year following replacement,and no further subsidence following over 5-year follow up.The prosthesis showed good contact to sclerotin,without loose.It is suggested that bone mass has great effects on cementtess prosthetic replacement.Autologous impaction bone graft for bone remodeling provides a good method for total hip replacement in patients combined with ankylosing spondylitis and severe osteoporosis.The clinical outcome is satisfactory.
