PFTK1,an important member of cyclin dependent kinase Cdc2 family,is over expressed in many malignancies.PFTK1 involves in multiple processes,such as regulation of cell cycle,tumor invasion and metastasis,and the Wnt signal transduction pathway,which has a significant impact on prognosis of tumor.

Objective To provide a clinical anatomic basis for the bi-pedicled gastrocnemius myocuta- neous flap which is to be used to repair defects of the Achilles tendon and posterior skin of the ankle.Methods In anatomic study,out of 30 cadaver specimens,bi-pedicled V-Y gastrocnemius myoeutaneous flaps were harvested to measure the downward sliding lengths of the flap when the knee was at flexion of different degrees.In clinic,12 patients with the Achilles tendon and posterior ankle skin defects were repaired with the bi-pedicled gastrocnemius myocutaneous flaps.The areas of composite defects ranged from 10 cm?6 cm to 6 cm?4 cm.They were followed up for four months to 12 years.Results The maximal sliding length of the flap reached (9.2?0.9)cm when the knee was at flexion of 90?.All the clinical flaps survived and ambulation of the patients recovered.The dorsiflexion and plantarflexion of the ankles reached 11.0??1.4?and 35.0??4.6?respectively.Conclusion This flap is suitable for one-stage repair of composite Achilles tendon defects.

A 69-year-old man presented with a 3-year history of scattered erythematous patches, perifollicular papules, acneiform lesions(such as milia, cysts) on the head, trunk and limbs as well as alopecia and peripheral eosinophilia. Histopathological examination revealed chronic focal dermal and perifollicular inflammatory infiltration with vascular proliferation and presence of a small number of eosinophils. He was initially diagnosed with folliculitis, and treated with antihistamines and antibiotics. Thereafter, lesional inflammation and pruritus were attenuated. However, plaques and alopecia developed in the occipital area 3 months later. The second histopathology of biopsy specimens revealed a dense dermal infiltrate of lymphoid cells and eosinophils, perifollicular infiltrate with numerous lymphoid cells, eosinophils and atypical lymphocytes migrating into hair follicles. Alcian blue stain showed epidermal mucinosis in follicles. Immunohistochemical examination showed positive staining of atypical cells for CD3, CD4, CD5, CD2, CD43 and ubiquitin carboxyl-terminal esterase L1 (UCHL1), but negative staining for CD20, CD79a, Epstein-barr virus, CD56, phosphoglucomutase-1, myeloperoxidase, CD7, or AE1 and AE3 monoclonal anti-keratin antibodies. T-cell receptor gene rearrangement was undetected. He was diagnosed with folliculotropic mycosis fungoides. Novel skin lesions still emerged after treatment with photochemotherapy (PUVA) plus acitretin. Follow up of the patient still continued.

Objective To study the effects of mild hypothermia on cardiomyocyte contractility improvement after ischemia-repeffusion injury and on the preservation of well-functioning mitochondrial respiratory capability.Methods A total of 50 newborn SD rats 1 ～ 2 days after delivery were sacrificed and their hearts taken to preserved in 4 ℃ cold D-hanks buffer solution with 0.12％ pancreatic proteinase and collagenase and then processed with 37 ℃ water bath to collect the cardiomyocytes cultured in DMEM medium with 10％ FBS for 5 days.The cardiomyocytes of rats were subjected to ischemia/reperfusion,in vitro,by oxygen and glucose deprivation(OGD)/oxygen and glucose restoration(OGR).The cardiomyocytes of rats after ischemia/reperfusion were divided into three groups:control group,hypothemia group and normothermia group.Contractile frequency and velosity were determined before OGD and 0 h,0.5h,1 h,1.5 h and 2 h after OGR.Ultrastructure changes of cardiomyocytes and mitochondrion were observed under transmission electron microscope(TEM)0 h and 2 h after OGR as well as assessment ot respiratory rate and respiratory control rate(RCR)with Clark oxygen electrode in each group.All data were analyzed with statistical software of SPSS 13.0.Results Contractile function of cardiomyocytes in hypothermia group and normothermia group declined to nadir at 0 h after OGR(P =0.000)and the contractile function of cardiomyocytes in hypothermia group was improved one hour later,compared with the normothermia group(P =0.000).Obvious swelling of mitochondrion was observed under TEM in normothermia group with little alteration after OGR.The RCR assessments indicated respiratory function in normothermia group was impaired after OGR(P =0.000)and this may be responsible for contractility dysfunction.Conclusions Mild hypothemia used after ischaemia can optimize the contractility of cardiomyocytes after a normothermia OGR,and the well-functioning respiratory capability of mitochondrion may be preserved in this process.

Objective To compare the changes of physiological parameters after cardiac arrest caused by asphyxia with that of cardiac arrest induced by ventricular fibrillation in rats and assess the values of the parameters on predicting ROSC and 24 h survival rate. Method Two groups of Sprague-Dwaley rats, which randomly (ramdom number) included 30 animals in each group, were investigated. Cardiac arrest were induced by asphyxia (AS group) or ventricular fibrillation(VF group). PETCO2, aortic pressure, left ventricular pressure and ECG of limb lead Ⅱ were recorded continuously, dP/dt4o was calculated with the windaq software. The parameters were compared between the two groups at baseline, precordial compression(PC) 10 s, PC 1 min, PC 3 min, ROSC 1 h and ROSC 2 h. The relations were explored between the parameters and ROSC/24 h survival rate. Results PETCO2,aortic pressure, left ventricular pressure and ECG have distinctive changes in the two groups. In group VF, PETCO2 of ROSC rats at BL, PC 1 min and PC 3 min were higher than those of Non-ROSC rats (P ＜ 0.05); PETCO2of 24 h survival rats at ROSC 1 h and ROSC 2 h were higher than those of 24 h death rats (P ＜ 0.05), which were not observed in the group AS. dP/dt40 and - dP/dt40 at ROSC 1 h and ROSC 2 h in group VF were higher than those in group AS (P ＜ 0.05). Conclusions Physiological parameters after cardiac arrest caused by asphyxia or that of cardiac arrest induced by ventricular fibrillation in rats have unique features respectively. PETCO2 in cardiac arrest caused by ventricular fibrillation may predict ROSC and 24 h survival rate. Researchers have to select the appropriate cardiac arrest model according their research purposes and clinical requirments.

Objective:To introduce recent progress on diagnosis and treatment of benign symmetric lipomatosis(BSL).Method:Detailed clinical data of 6 patients with BSL were reviewed and analyzed.We present a summary of the clinical symptoms,physical sign,diagnosis and therapeutic methods of BSL. And related literatures were discussed together.Result:All of 6 patients have excessive subcutaneous fat deposit predominantly around neck.One patients had upper extremity localizations. Six patients had the complication of left ventricular diastolic function changes,glucose intolerance or diabetes mellitus, chronic hepatopathy, hyperuricemia and sleep apnea syndrome in one or more. One patients with several symptoms occur simultaneously, another one female patient was accompanied by all symptoms but chronic hepatopathy. Five male patient were alcohol abusers. Tatal neck lipentomy and abstinence from alcohol were performed on 5 patients. One patient refused treatment.During a follow-up of 3 months to 4 years, one patients was relapsed again,and no recurrence was seen in another 4 patients. All pathological results were nonencapsulated fat. Conclusion:BSL is a lipodystrophy caused by diffuse fatty tissue, symmetry deposition in the neck and shoulder subcutaneous fascia space or deep fascial space .The highest incidence favors to middle-aged man who is alcoholist. Chronic alcohol addiction and typical clinical symptoms help to diagnosis BSL. Lipectomy represents a successful procedure in treating BSL.

BACKGROUND:Currently, literatures about autologous vein transplantation are few, and the research on the effect of different parts of autologous vein transplantation are not found yet. OBJECTIVE:To summarize the experiences of establishing the fistula using autologous vein transplantation so as to investigate the method of improving the success rate of surgery. METHODS:We analyzed retrospectively the data of 40 cases of establishing the fistula using autologous vein transplantation, and then compared the successful rate of autologous vein transplantation fistula, blood flow and operating time, thereby analyzing the influence of diabetes melitus on the successful rate of autologous vein transplantation fistula. RESULTS AND CONCLUSION:The successful rates of autologous vein transplantation fistula at different parts ranging from high to low were as folows: the cephalic vein, great saphenous vein, basilic vein and smal saphenous vein. Blood flow of the upper limb for vein transplantation fistula was obviously higher than that of the lower limb (P < 0.05). The operating time of autologous vein transplantation fistula was longer in the upper limbs than in the lower limbs (P < 0.01). For patients with diabetes melitus, the successful rate of autologous vein transplantation was markedly lower than those with no diabetes melitus (P < 0.01). For the hemodialysis patients with poor upper limb superficial vein, autologous vein transplantation is a better way of establishing the vascular access. Vein transplantation of the upper limbs is better than that of the lower limbs in success rate and operating time. Autologous vein transplantation fistula is not suitable for the patients with diabetes melitus.

Human cytomegalovirus (HCMV) is a DNA virus and serious opportunistic pathogen for both newborn and immunocompromised individuals.To research technique for gene silence and antiviral agents, ribozyme M1GS-T6 was constructed from external guide sequences(EGSs)that consist of a sequence complementary to HCMV UL54 gene RNA and M1 RNA, the catalytic RNA subunit of RNase P from Escherichia coli. The results showed that M1GS can efficiently cleave the mRNA sequence encoding UL54 protein in vitro.

Objective To investigate the clinical value for treatment of diabetic foot with PTA and PTA combined cinepazide maleate.Methods In 24 cases of diabetic associated vascular disease of lower limb,12 cases were treated with PTA and other 12 cases were treated with PTA combined einepazide maleate,We analysed and compared clinical effects before and after the procedure,together with 3 months follow up.Results In patients treated with PTA,the clinical symptom scores of posttreatment and follow-up decreased;ABI and TcPO_2 increased significantly.The clinical symptom score and ABI of follow-up remained,stable,but TcPO_2 decreased significantly.Control angiography showed improvement in degree of vascular stenosis and peripheral staining of 11 patients after treatment.The vascular patency remained in 12 patients and the peripheral staining decreased in 7 patients on follow-up.In patients treated with VIA combined cinepazide maleate,the clinical symptom score,ABI and TcPO_2 after treatment and on follow-up showed no signifcant changes compared with those in patients treated by PTA.F,Control angiography showed that the degree of vascular stenosis and peripheral staining were improved in 12 patients after treatment.The vascular pateney was maintained and peripheral staining was improved on follow-up.Before and after treatment,there were no significant differences in clinical symptom score.ABI and TcPO_2 between patients treated with PTA and PTA combined cinepazide maleate,however,there were significant differences in clinical symptom score and TcPO_2 on follow-up.Conclusion PTA can significantly improve clinical symptom of diabetic foot and the application of cinepazide maleate is a benefitial and necessary supplement.PTA combined cinepazide maleate can be taken as one of the conventional treatment plans for diabetic foot.(J Intervent Radiol,2007,16:811-815)

OBJECTIVETo compare the efficacy difference in the treatment of functional dyspepsia between acupuncture at the acupoints selected by pattern/syndrome differentiation and domperidone.

METHODSSeventy cases were randomized into an acupuncture group (35 cases) and a western medication group (35 cases). In the acupuncture group, Zusanli (ST 36) and Neiguan (PC 6) were selected. Taichong (LR 3) and Neiting (ST 44) were added for excess syndrome while Gongsun (SP 4) and Yinlingquan (SP 9) were added for deficiency syndrome. A pair of electrodes was attached to one acupoint and an assistant point (2 mm next to the acupoint centripetally) and stimulated with disperse-dense wave at 2 Hz/100 Hz, once a day. In the western medication group, domperidone was prescribed for oral administration, 10 mg each time, three times a day. In the two groups, the treatment of 5 days made one session and 4 sessions were required totally. Nepean dyspepsia index (NDI) was compared after treatment, 1, 2, 3, 4 and 5 months after treatment between the two groups respectively.

RESULTSThe score of symptom and score of life quality in NDI after treatment and at each follow-up time point were improved obviously in the acupuncture group as compared with those before treatment (all P < 0.01). In the western mediation group, the score of symptom and the score of life quality in NDI after treatment and in follow-up of 1, 2 and 3 months were improved obviously as compared with those before treatment (all P < 0.01), but the differences were not significant in follow-up of 4 and 5 months (both P > 0.05). Compared with the western medication group, the symptom score of NDI was reduced obviously after treatment and in each time point of follow-up in the acupuncture group (P < 0.05, P < 0.01), and the score of life quality was increased obviously (P < 0.05, P < 0.01).

CONCLUSIONAcupuncture at the acupoints selected by pattern/syndrome differentiation and domperidone are effective in the treatment of functional dyspepsia. Domperidone is unsatisfactory in the long-term effect, but acupuncture achieves the positive short-term and long-term effects on functional dyspepsia.
