Objective: To compare the long-term outcomes in ST-elevation myocardial infarction (STEMI) patients who underwent early or late delayed percutaneous coronary intervention (PCI) using drug-eluting stents (DES). Methods: This study was a retrospective, observational and single-center study. Consecutive STEMI patients (n=977), who admitted to Fuwai Hospital in 2013 and underwent successful selective PCI using drug-eluting stents (DES) within 3 to 35 days after symptom onset were enrolled and divided into the early delayed PCI (3-14 d) group (n=495) and the late delayed PCI (15-35 d) group (n=482). General clinical data of the patients and related data of coronary angiography and interventional therapy were collected, and the endpoint events were followed up. The primary endpoint was 2-year major adverse cardiac and cerebrovascular events (MACCE) including cardiac death, recurrent myocardial infarction, definite or probable stent thrombosis and ischemic stroke. The secondary endpoint was 2-year ischemia-driven target vessel revascularization. The incidence of endpoint events of the two groups was compared, and it was compared again after the primary baseline characteristics such as age and gender were matched by the propensity scoring method at a 1∶1 ratio. Results: A total of 910 (93.1%) patients who underwent delayed PCI were transferred from other hospitals, and 292 (29.9%) patients received thrombolysis before PCI. The time interval before PCI was 14 (10, 20) days. The incidence of 2-year MACCE (3.0%(15/495) vs. 2.3%(11/482), P=0.468) and ischemia-driven target vessel revascularization (3.8%(19/495) vs. 5.0%(24/482), P=0.385) were similar between the two groups. The incidence of 2-year MACCE (3.3%(15/453 vs. 2.4%(11/453), P=0.426) and ischemia-driven target vessel revascularization (4.2% (19/453) vs. 4.9%(22/453), P=0.632) were also similar between the two groups after matching propensity score. Conclusion The long-term clinical outcomes after early delayed PCI using DES is statistically equivalent to those of late delayed PCI using DES for STEMI patients who missed the time window for emergency PCI.

Objective To illustrate the clinical and pathological features of Chinese upper tract urothelial carcinoma (UTUC) patients and to investigate the regional difference and the possible prognostic factors.Methods A retrospective study was performed on 2 628 patients from 9 centers of three different regions (Beijing:2 centers with 1 022 cases,Shanghai:1 center with 814 cases,Sichuan:6 center with 792 cases).The median age was 68 (range 20 to 93) and the mean age was 66.3.There were 1 447 male patients (55.1％) and 1 181 female patients (44.9％).The clinical information,pathological outcomes and prognosis were collected and analyzed based on South (Shanghai and Sichuan) and North (Beijing)region.Results The distribution of Ta + T1,T2,T3 and T4 was 914 (34.8％),715 (27.2％),857(32.6％) and 142(5.4％).Patients from North were more likely to be female (55.9％ vs.38.0％,P＜0.001) and suffer from ureteral tumors (43.4％ vs.35.9％,P ＜ 0.001);while in patients from South higher tumor stage(T3 or T4,42.5％ vs.31.0％,P ＜ 0.001),high grade(72.0％ vs.34.0％,P ＜0.001) and larger tumor size [(3.73 ±2.17) cm vs.(3.36 ±2.02) cm,P＜0.001] were more prevalent.Subgroup indicated that female patients in North had obviously lower tumor stage (T3 or T4,27.2％ vs.35.9％,P =0.014),while relatively higher tumor stage were noticed in female patients in South (T3 or T4,48.2％ vs.38.9％,P =0.004).The median follow-up was 41 (1-206) months,and 963 patients (36.6％) died including 815 (31.0％) died from cancer.In North female patients had better 5-year overall survival (75.5％ vs.62.2％,P ＜0.001) and cancer-specific survival (78.3％ vs.65.0％,P＜0.001),but in South gender had no impact on overall survival (58.5％ vs.60.1％,P =0.927) or cancer-specific survival (62.0％ vs.65.8％,P =0.345).Conclusions This study demonstrated that in Chinese patients with UTUC,those from North were featured for lower tumor stage and grade,higher proportion of females and females had better survival.High age,high tumor stage and grade,large tumor diameter,and the presence of lymph node metastasis or lymphovascular invasion were risk factors for poor prognosis in Chinese UTUC patients.

Objective To study the clinical effect of the secondary prevention of chronic ankle instability (CAI) for nursing staff.Methods From September 2014 to January 2015, we screened 100 nurse with functional ankle instability in Shandong Provincial Hospital .The subjects were divided into the intervention group ( n=51 ) and the control group ( n =49 ) by random number table .The nurses of intervention group accepted measures of the secondary prevention , including bundle health education , bracing and rehabilitation , while the nurses of control group received only routine health education .Before intervention and 4 months later , we evaluated the ankle instability by Chinese version Cumberland ankle instability tool ( CAIT) in two groups and compared the intervention effects and relevant knowledge of the two groups .Results Before the intervention, the CAIT score of intervention group was (19.0 ±4.8), and was (28.2 ±3.0) after intervention ( t=9.210,P<0.05);the CAIT score in the control group was (19.0 ±5.1) before intervention and (21.3 ± 5.2) after intervention (t=1.509,P>0.05); after intervention, the difference of two groups had statistical significance (t=9.317,P<0.05).Conclusions The secondary prevention of CAI can improve CAI nurse staff′s ankle stability and the recognition level of CAI prevention knowledge , and promote the clinical symptom prevention effectively , so it has significance for the improvement of nurse′s ankle function .

Objective To evaluate the intervention effects of systemic rehabilitation training on postoperative disuse shoulder dysfunction in hand injury patients received abdominal pedicled skin flap transplantation. Methods The 92 patients received same operation of abdominal pedicled skin flap surgery for unilateral hand in Hand and Foot Surgery Department of Provincial Hospital Affiliated to Shandong University and were divided into two groups, in which 45 patients as control group from March to April 2014 and 47 patients as experimental group from June to July 2014. The patients of control group received conventional therapy and nursing, while the ones of experimental group received systematic rehabilitation training by nurses and doctors before, during and after operation. Shoulder function was scored at the day 1 and day 7 after the pedicle division operation according to the shoulder joint function assessment scale, and we employed SPSS 20. 0 to analyze the results. Results The shoulder function scores of experimental group patients were (72. 96 ± 4. 72) and (87. 91 ± 4. 74) at the day 1 and day 7 after the pedicle division operation, which were better than the scores of control group patients, [(65. 11 ± 6. 74) and (79. 38 ± 7. 31)] (t =6. 492,6. 677;P <0. 01). Conclusions The systemic rehabilitation training program, which requirements were definite, and guidance was standard and easy to perform, can significantly improve the shoulder function of the patients received abdominal pedicled skin flap transplantation.

Objective To analyze features of the lateral leg peroneal artery perforator free flap,and study the clinical application of free peroneal artery perforator flap transplantation for repairing forefoot defects.Methods Retrospectively analyzed 9 patients with forefoot defects which had been repaired with free lateral leg peroneal artery perforator flap transplantation.In this group,the skin and soft tissue defects size were 4.5 cm ×4.0 cm-13.5 cm × 6.5 cm,Focused on analyzing the features of forefoot skin and soft tissue defects,the design and harvesting of lateral leg peroneal artery perforator flap,and vascular anastomosis and vessel matching,meanwhile,follow-up the survival condition and appearance of the flap,the function of foot and ankle after operation.Results In the 9 cases,the larger myocutaneous perforator arising from peroneal artery,accompanying 2 vena comitans,were found slightly above the midpoint of the line between fibula head and lateral malleolus in lateral leg.The flaps transfered to repair forefoot defects,artery end-end anastomosis:in 5 cases cutaneous branch of peroneal artery to dorsal artery of foot,in 4 cases by cutaneous branch of peroneal artery to dorsal metatarsal artery;vein end-end anastomosis:in 1 case 2 accompanying veins of peroneal artery cutaneous branch to 2 accompanying veins of dorsal artery of foot,in 5 cases 1 accompanying vein of peroneal artery cutaneous branch to 1 accompanying vein of dorsal artery of foot or metatarsal,in 3 cases 1 accompanying vein of peroneal artery cutaneous branch to 1 accompanying vein of dorsal artery of foot or metatarsal,simultaneously,the another accompanying vein of peroneal artery cutaneous branch to 1 dorsal superficial vein of the foot.All the 9 flaps survived,and no vessel articulo happened.The venous return of flaps had no significant difference between repairing 1 vein and 2 veins in gross appearance.All wounds healed in one-period.Followed-up 2-6 months postoperative,1 patient was performed flap reshaping due to flap fat and clumsy at 5 months postoperative,others,the skin texture and appearance of the flaps were good and satisfactive.Conclusion Free transplantation of the lateral leg peroneal artery perforator flap broke away from the bondage of pedicled flap,had more freedom in flap design,and effectively controlled the trauma of donor and recipient site.The flap have the merits,blood vessel anatomy is relatively stable,blood supply is reliable,harvesting is simple,skin texture is similar to the forefoot and the effect is better,operation of the donor and recipient sites can accomplish under a identical anaesthesia and tourniquet.Thus,the lateral leg peroneal artery perforator free flap is an effective metheod in reparation of the forefoot defects.

Objective To investigate the differential gene expression in chronic hepatitis B (CHB) patients with typical syndromes of traditional Chinese medicine ( TCM) syndromes, and to explore the relationship between TCM syndromes and gene expression. Methods Peripheral blood samples were collected from CHB patients and healthy volunteers before treatment. After total RNA of leukocytes was isolated, the gene expression profiles were detected by microarray. The expression levels of partial genes were tested by real-time quantitative reverse transcription-polymerase chain reaction (RT-PCR) . Results Microarray analysis results showed that there were significant differences of gene expression between CHB patients and healthy volunteers, and among CHB patients with the syndrome of liver-qi stagnation and spleen deficiency, syndrome of damp-heat accumulation, and syndrome of liver-kidney yin deficiency. The results of gene ontology ( GO) and signal pathway analysis between the healthy control and CHB patients with various syndromes showed that the specially-regulated genes of CHB patients with liver-qi stagnation and spleen deficiency were mainly related to cytokinetic process, those in patients with dampness-heat accumulation were mainly related to the positive regulation of lipid storage, and those of patients with liver-kidney yin deficiency were mainly related to the activities of nitric oxide synthase regulator. The real time RT-PCR for partial genes presented the similar results with those of gene microarray. Conclusion There are specific expression profiles of differential genes and significant differential genes in CHB patients with the syndrome of liver-qi stagnation and spleen deficiency, syndrome of damp-heat accumulation, and syndrome of liver-kidney yin deficiency, which may be the molecular foundation for the classification of TCM syndromes of CHB patients.

To investigate the differential gene expression profile in two typical traditional Chinese medicine (TCM) syndromes of patients with chronic hepatitis B (CHB), and to find the relationship between TCM syndromes and gene expressions.

ObjectiveTo introduce the new method of full reconstruction for Ⅰ to Ⅲ-degree finger defect.MethodsFor reconstruction of Ⅰ to Ⅱ-degree finger defect, the surgery procedure was as follows:Harvest part of nail,skin and dorsal part of distal phalanx from hallux to form a composite flap,and then the flap was transplanted to the finger stump to reconstruct the defect part of the finger.The design of the composite flap was according to the recipient part. For reconstruction of Ⅲ-degree finger defect, the skin included in the flap could be designed according to the recipient part, but the bone can only be harvested from the fibulodoral part of the hallux and far from the insertion of the extensor hallucis longus tendon, which means the length was limited.If the bone length was not enough,one bone mass with appropriate size and shape was harvested from the iliac bone and connected with the bone of the composite flap. Some cases of Ⅲ-degree finger defect were reconstructed by harvesting interphalangeal joints from the second toes to reconstruct distal interphalangeal joints(DIP). The bone defect was reconstituted by bone mass from the iliac bone to conserve the contour of the second toe.The hallux wound was covered by a local flap or free flap transplantation.ResultsOne hundred and eighteen cases (126 fingers) of Ⅰ-degree defect, one hundred and eighty-seven cases (201 fingers) of Ⅱ-degree defect and 90 cases (111 fingers) of Ⅲ-degree finger defect were applied full reconstruction. All the reconstructed fingers survived completely and the configurations were similar to real fingers. Followed up our work on 150 fingers from a number of patients, between 1 and 11 years after the original surgery.Total ranges of motion of the reconstructed fingers got to over 180°.The reconstructed DIP joints had the range of motion of 15°-40°. The donor halluxes and toes were conserved with the normal length,relatively primary appearance and full function. ConclusionFull reconstruction for Ⅰ to Ⅲ-degree finger defect has great advantages in that the reconstructed finger has very realistic configuration as well as ideal function and the donor hallux is conserve well.

ObjectiveTo explore methods of donor repair of the great toe-nail flap in finger reconstruction surgery.MethodsFrom December 1998 to December 2010, various kinds of flaps were used in 511 donor sites to repair the great toe-nail flaps,including:32 dorsal pedal artery flaps;twenty-four first dorsal metatarsal artery flaps;twenty-one second dorsal metatarsal artery flaps;forteen anterior malleolar flaps;seventeen medial tarsal artery flaps;seventy-nine lateral tarsal artery flaps;one hundred and six plantar metatarsal flaps,seventy-nine flaps from second toe;fifteen flaps from mid/lower leg and 124 freed flaps.ResultsAfter postoperative 6 months to 11 years of follow-up, repaired donor sites of great toe-flaps all survived successfully,with ideal outlook and function.ConclusionThere are many kinds of methods for donor site repair of the great toe-nail flap,and each kind of method has its own advantages and disadvantages. Among these flaps, plantar pedal artery flap and free groin flap are amony the best ones.

The use of the accessory nerve as a donor is one of the best possibilities for treatment of the brachial plexus in case of paralysis due to root avulsion. In this paper, a brief history of the use of accessory nerve tran sfer for treatment of brachial plexus injury and recent development in the anato my of accessory nerve are introduced. The nerve transfer methods and the effects of the accessory nerve are discussed in particular. The progress in and the dev elopment trend of the accessory nerve transfer methods are also analyzed. It is advisable that the accessory nerve is transferred to restore the suprascapular n erve so as to obtain shoulder abduction. And it is a clinical trend that the dis tal terminal branch of the accessory nerve is used and the function of the upper part of the trapezius muscle is preserved in the transfer. At last, the factors affecting functional outcome in accessory nerve transfer are discussed.
