ObjectiveTo compare the effect of salt bag compression and arterial compressor haemostat for patients after cerebral angiography.Methods Four hundred and ninety-five patients undergoing cerebral angiography were divided into two groups according to the methods of arterial compression:salt bag compression group (243 cases) and arterial compressor haemostat group (252 cases) in which 131 patients used the YM-GU-1229 arterial compressor haemostat and 121 patients used the NZ-1 arterial compressor haemostat.The associated complications within 3 days were recorded.ResultsThe incidence of complications in salt bag compression group was 3.70％(9/243),in arterial compressor haemostat group was 9.92％ (25/252),and there was significant difference between the two groups(P ＜ 0.01 ).The incidence of complications in YM-GU-1229 arterial compressor haemostat was 12.21％ ( 16/131 ),in NZ-1 arterial compressor haemostat was 7.44％(9/121 ),and there was no significant difference between the two arterial compressor haemostats (P ＞ 0.05).ConclusionThe incidence of complications of arterial compressor haemostat is higher than that of salt bag compression.

Objective To study the operation design and surgical methods for terminal surgical reconstruction of severe post-midfacial fracture deformities. Methods From July 1997 to December 2002,11 cases of severe and complex post-midfacial deformities were reconstructed. There were four cases with Le Fort Ⅰ, Ⅱ and Ⅲ fractures,five with Le Fort Ⅰ and Ⅲ fractures and two with Le Fort Ⅰ and Ⅱ fractures combined with right orbital-zygomatic fractures. Typical bicoronal and subcilliary incisions and intra-oral approach were employed to expose all the fractured sites. The displaced orbito-zygomatic bone fragments were repositioned firstly in order to reconstruct the outer midfacial framework. Then, the malunited maxilla was reduced to its proper position after osteotomy of Le Fort Ⅰ fractures under the guidance of mandible through inter-maxilla fixation. The depressed naso-orbital region were reconstructed using autogeneous outer cranial table. Meanwhile, nasal framework reconstruction, medial canthal tendon reapproximation and plasty, and fractured orbital walls repairing were performed to correct the enophathalmos. Results All the cases recovered well and the post-operative facial appearance and occlusal function were improved obviously. Conclusions Complex midfacial fractures, usually involving orbital-zygomatic bone, naso-orbit and maxillary bone, can be well improved through osteotomy and reduction, internal rigid fixation with mini-plates and screws, autogenenous bone grafting and framework reconstruction.

Objective To introduce a new method for correcting square face deformity.Methods This operation consists of malar reduction (MR)and mandibular angle osteotomy (MAO),which could be done simutaneously or at different time.Results A total of 21 patients with square face deformity accepted MR and MAO in which 12 cases were done simutaneously and 9 cases at different time.After this procedure, the width of the mid face and the lower face reduced by 15.3?3.2mm and 14.2?2.5mm, respectively. A11 the cases achieved satisfactory results without complications.Conclusion This method can effectively correct square face deformity by reducing the width and protrusion of the mid face and the width of the lower face.

Objective To explore the correlation between Parkinson's disease(PD) and living habits.Methods 114 PD cases from ongoing PD prevalence survey in Beijing region and the neurological clinic center of Beijing Union Hospital and 205 controls matched on gender, race and residence were recruited in this study. Through in-person questionnaire interview, general data and living habits such as smoking, tea drinking and alcohol drinking were obtained and analyzed by population-based case control study.Results We observed reduced risk for PD in smokers(OR:0.538; 95%CI: 0.290, 0.998) and tea-drinkers(OR:0.199; 95%CI:0.114,0.346). There was no significant correlation between alcohol drinking and PD.Conclusion An inverse correlation exists in PD with smoking or tea drinking except for alcohol drinking.

Objective To evaluate the gastroesophageal reflux symptom in patients who underwent continuous ambulatory peritoneal dialysis (CAPD) and the efficacy of proton pump inhibitor (PPI) in treating gastroesophageal reflux. Methods Fifty-eight CAPD patients with good clinical and complete dialyzed eondition,who was admitted to the hospital between Jan. 2008 and July 2008, were inquired about their gastroesophageal reflux symptoms using reflux disease questionnaire (RDQ). The patients who had RDQ≥6 and <12 were received esomeprazole 20 mg daily, while those with RDQ≥12 were received esomeparzole 20 mg twice daily. RDQ score was reevaluated 4 weeks after treatment.Results The common symptom was regurgitation (64.70%), followed by acid reflux (52.9 %), non-cardic chest pain (47.1. %) and heart burn (17. 6%). After 4-week treatment, the RDQ was significantly decreased (P< 0. 05). But there was no difference in outcome of treatment between patients with RDQ≥ 12 and RDQ< 12 (P=0. 059). Conclusion The gastroesophageal reflux symptom in CAPD patients can be relieved by PPI administration, but a larger clinical trial is needed to evaluate the course and efficacy of treatment.

The prognosis of malignant tumors of the digestive system is still a matter of close attention in the medical and health field. At present, evaluating the prognosis of patients with digestive system malignant tumors is mainly based on the TNM staging of the tumor after surgery. As one of the ten characteristics of cancer, inflammatory indicators have certain guiding significance for the prognosis and treatment of patients with malignant tumors of the digestive system. As a new type of inflammation index, the systemic inflammatory response index is significantly better than other traditional inflammatory indexes in evaluating the prognosis of patients with digestive system malignant tumors. This article reviews the related studies on the systemic inflammatory response index in evaluating the prognosis of digestive system malignant tumors.

BACKGROUND: Enophthalmos deformity is the most common complication caused by orbital blow-out fractures, and others are diplopia and worsening of visual acuity. Since the therapeutic result of orbital blow-out is not satisfactory and many complications exist after operation, it is still a dispute to select implantation materials and therapeutic regimens.OBJECTIVE: To observe the therapeutic effect and assess the improvement of visual function by surgical reconstruction with porous high-density polyethylene (Medpor) for the correction of enophthalmos deformity caused by orbital blow-out fractures.DESIGN: A pre-and postoperative controlled study.SETTING: Beauty Center for Trauma Repair,Plastic Surgery Hospital,Peking Union Medical College, Chinese Academy of Medical Science .PARTICIPANTS: Totally 56 patients with orbital blow-out fractures who had enophthalmos deformity caused by fists or traffic accidents, treated at Beauty Center for Trauma Repair,Plastic Surgery Hospital, Peking Union Medical College, Chinese Academy of Medical Science, were selected in this study from December 1996 to March 2004. Final diagnosis were made with case history, X-ray film, two-demensional and three-dimensional CT before operation. 24 cases were accompanied with other areas fractures such as zygoma and nasal bone, 34 cases with diplopia, 35 cases with visual acuity worsening after injured.METHODS: ①Material implantation: Exposure of the orbital floor, inferior and medial walls could be performed through a 2 mm inferior subciliary incision of 3 cm long. To approach the orbital rim via a dissection plane anterior to the orbital septum, sub-periosteal dissection was then performed over the orbital rim, and along the orbital floor to the orbital apex. Mobilized the soft tissue from the bone throughout the entire area of fractures and re-position it to its proper position. Took Medpor (Type 6331) sheets as the implantation materials, trimmed Medpor sheets according to the radian and anatomic form, and 2 mm larger than the defect rim was needed.If other operations were needed during the operation, they could be done.Mannitol and dexamethasone should be used just postoperatively to decrease edema of the orbital contents and reduce inner orbital excessive pressure. ②Functional evaluation standard: Diplopia: completely disappear meant recovered, less diplopia residual meant improvement, no improvement meant inefficacy. Enophthalmos: marked improvement meant the degree of enophthalmos stabilizated at below 2 mm, less improvement meant stabilizated at above 2 mm.MAIN OUTCOME MEASURES: ①Improvement of enophthalmos; ②Improvement of diplopia ; ③Improvement of visual acuity.RESULTS: ①All 56 cases of enophthalmos deformities caused by orbital blow-out fractures improved greatly. ② Of all the 34 patients with diplopia, 27 recovered. ③ 9 patients' visual acuity of 35 improved with different degrees. No diplopia or visual acuity worsening occurred. With a follow-up ranging from 2 months to 5 years, the degree of enophthalmos stabilizated at below 2 mm, and no relapse and other complications occurred.CONCLUTION: Medpor has such advantages as better histocompatibility,fewer complications and better visual function improvement, so it is the preferred implantation material for correcting enophthalmos deformity caused by orbital blow-out fractures.
