IgG4-Related Tumefactive Lesions at the Pulmonary Artery Causing Stenosis of Bilateral Primary Branches and Resultant Pulmonary Hypertension.

IgG4-related disease (IgG4-RD) is a newly recognized but rare entity involving multiple organs, with autoimmune pancreatitis, retroperitoneal mass, and the inflammation of glands being typical in most cases. IgG4-related perivascular lesions, although uncommon, have been increasingly reported in recent years. Diagnosis of IgG4-RD relies on comprehensive consideration of characteristic histopathological and immunostaining results, clinical and imaging findings, and serological results according to several widely recognized diagnostic criteria.

Interaction between alcohol consumption and CYP 2C19 gene polymorphism in relation to oesophageal squamous cell carcinoma.

Objectives: The purpose of this study is to explore the relationship between the interactions of CYP2C19 gene polymorphisms and several environmental factors and oesophageal squamous cell carcinoma (OSCC).

Methods: In a case-control study of OSCC patients (n = 350) and healthy controls (n = 350), we investigated the roles of polymorphism in the CYP2C19 gene by the use of polymerase chain reaction--restriction fragment length polymorphism (PCR - RFLP) analysis.

Results: The CYP2C19(*)3 AG+AA genotype was significantly more prevalent in OSCC patients (10.

[Controlled clinical trials of initial observation on therapeutic effects of moxibustion for osteoarthritis of the knee: multi-center clinical effect].

Objective: To compare therapeutic effects between moxibustion and infrared therapy for the treatment of knee osteoarthritis.

Methods: From January 2007 to June 2008 period, 65 patients with knee osteoarthritis were divided into treatment and control groups randomly uniform random number table generated from SAS statistical software. Among 35 patients in the treatment group, 17 patients were male and 18 patients were female, ranging in age from 45 to 75 years, with an average of (61.

[Evaluation of the clinical effect of knee osteoarthritis treated with moxibustion according to WHOQOL-BREF].

Objective: To investigate and research WHOQOL-BREF evaluation of the clinical effect of application of moxibustion for treatment of knee osteoarthritis, to provide clinical according for the treatment.

Methods: From January 2007 to June 2008, 90 cases of knee osteoarthritis were randomly divided into treatment group and control group. In treatment group there were 45 cases included 16 males and 29 females with an average age of (62.

[Effect of moxibustion in treating knee joint osteoarthritis and its relation with contents of hyaluronic acid in serum and synovial fluid].

Objective: To investigate the clinical effects of moxibustion (Mox) in treating knee joint osteoarthritis, and to detect the change of hyaluronic acid (HA) level in serum and synovial fluid (SF) for evaluating its significance.

Methods: Thirty OA patients were treated with Mox applied on inner and outer hsiyens and Ashi point for 10 min once a day, 5 times a week for 3 months and the therapeutic efficacy was evaluated. Serum and SF levels of HA were measured by radio-immunoassay before and after the 3-month treatment, and compared with those from 30 non-OA persons for normal control.

Three-dimensional finite element analysis of lumbar vertebra loaded by static stress and its biomechanical significance.

Objective: To explore the mechanical behavior of lumbar spine loaded by stress and provide the mechanical basis for clinical analysis and judgement of lumbar spine fracture classification, mechanical distribution and static stress.

Methods: By means of computer simulation method, the constructed lumbar spine three-dimensional model was introduced into three-dimensional finite element analysis by software Ansys 7.0.

Shape memory Ni-Ti alloy swan-like bone connector for treatment of humeral shaft nonunion.

From August 1990 to December 2007, 156 patients with humeral shaft nonunion were treated with our patented Ni-Ti shape memory alloy swan-like memory pressure connector (SMC). The SMC device cooled with ice before implantation was warmed to 40-50 degrees C after implantation to produce balanced axial and compression forces to stabilise the fracture three-dimensionally. This combined with autologous bone grafting achieved bone tissue regeneration in the fracture and promoted smooth recovery of joint function, with a nonunion healing rate of 98.

[Treatment of severe crush syndrome caused by earthquake: a report of 35 cases].

Objective: To discuss the diagnosis and treatment of the crush syndrome in the earthquake.

Methods: Thirty-five patients with crush syndrome caused by earthquake were involved the retrospective study. The role of nutritional support, active wound treatment and hemodialysis on the patients' recovery was observed.

[Diagnosis and treatment of peripheral nerve injury in Wenchuan earthquake: a report of 14 cases].

Objective: To discuss the diagnosis and treatment of peripheral nerve injury in the earthquake.

Methods: Fourteen patients with peripheral nerve injury injured in the earthquake were involved the retrospective study. All cases accepted the timely diagnosis and treatment including anastomosis and repair of the nerve and other conservative treatments.

[Analysis of traumatic conditions on casualties evacuated from Wenchuan earthquake area].

Objective: To investigate and analyze the traumatic conditions on the casualties evacuated from Wenchuan earthquake area.

Methods: Traumatic conditions of 34 patients evacuated to Changhai hospital were investigated. Meanwhile, classification of traumatic conditions and therapeutic methods was analyzed.

[Treatment of the aged wounded patients evacuated from Wenchuan earthquake area].

Objective: To explore the therapeutic strategies of the aged wounded patients evacuated from Wenchuan earthquake area.

Methods: The characteristics of traumatic conditions and therapeutic methods of 14 aged wounded patients evacuated from Wenchuan earthquake area were retrospectively analyzed.

Results: All cases accepted the effective treatment for 4 to 8 weeks and attained good recovery.

[Reconstruction of condyle in treatment of refractory condylar nonunion and defect of humerus].

Objective: To discuss the strategy of condylar reconstruction in the treatment of refractory condylar nonunion and defect of humerus.

Methods: From September 1998 to September 2005, 18 patients with refractory condylar nonunion concomitant withdefect of humerus were treated. The series included 12 males and 6 females, aged 18 to 60 years.
