BACKGROUND: Ischemic osteonecrosis of femoral head can cause dysfunction of the patients and the most frequently advocated treatment for advanced osteonecrosis of femoral head is total hip arthroplasty. But the reason is unknown. A potential cause in patients with osteonecrosis of femoral head is abnormal cancellous bone in the proximal femur which is short of further investigation.OBJECTIVE: To probe into proximal femoral change of patients with ischemic osteonecrosis of the femoral head.DESIGN: A non-randomized concurrent controlled study based on the patients.SETTING: Department of Traumatic Surgery, Affiliated Hospital of Medical College of Qingdao UniversityPARTICIPANTS: This study was done at the Department of Traumatic Surgery, Affiliated Hospital of Medical College of Qingdao University from September 1999 to May 2003. Eighteen patients with osteonecrosis of the femoral head including 12 males and 6 females with the average age of (50 ± 5) years and eighteen patients with osteoarthritis of the hip attended including 10 males and 8 female with the average age of(62 ±3)years were involved in this study.METHODS: Histological examination of the femoral heads and cancellous bone biopsies from four regions of the proximal femur in 18 patients with osteonecrosis of the femoral head following total hip arthroplasty was perforned. Eighteen patients with osteoarthritis were set as control group. All histological specimens were examined in a double-blinded fashion.MAIN OUTCOME MEASURES: The femoral neck, the greater trochanter, the lesser trochanter, the necrosis scoring and necrosis positive rate of shaft of femur of the patients in the two groups.RESULTS: Extensive osteonecrosis was found in the proximal femur up to 4 cm below the lesser trochanter in the group with osteonecrosis. The osteonecrosis scoring was 82 and 16 in the osteonecrosis group and control group respectively and the osteonecrotic positive rate was 63.89% and 19.44% respectively, There was an overall statistically significant difference in the extent of osteonecrosis death in the proximal femur between the two groups ( P < 0. 001 ).CONCLUSION: Bone change of proximal femur might be one of the reasons for the early failure of total hip replacement reported in patients with osteonecrosis of the femoral head.

Objective To study the clinical features,diagnosis and treatment of Dieulafoy′s disease.Methods The clinical characteristics,diagnosis,methods of treatment and efficacy of treatment of 19 cases of (Dieulafoy′s) disease were analyzed retrospectively.Results All cases presented as abrupt upper gastrointestinal bleeding.12 cases(63.2%) were diagnosed at the first,and 4 cases (21.1%) at the second ecdoscopic examination,and 3 cases(15.8%) were diagnosed at exploratory operation.Hemorrhage stopped successfully after one endoscopic treatment in 14 cases and after 2 endoscopic treatments in 1 case.4 cases were cured by operation(including 1 case with re-bleeding 72 hours after endoscopic treatment).Conclusions Emergency endosopic examination is the best way to diagnose Dieulafoy′s disease and endoscopic treatment is the method of choice to treat it.If hemorrhage fails to stop after endoscopic treatments,surgical operation should be (performed) immediately.

Objective To evaluate the effect of dexmedetomidine on the postoperative pulmonary function in patients undergoing laparoscopic operation.Methods Eighty American Society of Anesthesiologists physical status Ⅰ or Ⅱ patients,aged 45-64 yr,weighing 45-70 kg,undergoing laparoscopic radical resection of rectal cancer,were divided into 2 groups (n =40 each) using a random number table:control group (group C) and dexmedetomidine group (group Dex).General anesthesia combined with epidural anesthesia was used.In group Dex,dexmedetonidine was intravenously infused as a bolus of 0.3 μg/kg over 10 min after epidural catheterization and before induction of general anesthesia,followed by an infusion of O.4 μg · kg-1 · h-1 starting from the end of tracheal intubation until 30 min before the end of operation.The equal volume of normal saline was given instead in group C.After epidural catheterization and before infusion of dexmedetomidine (T0),immediately before termination of pneumoperitoneum (T1) and at 1,6 and 24 h after operation (T2-4),blood samples were taken from the peripheral vein for determination of concentrations of serum interleukin-6 (IL-6),IL-10,tumor necrosis factor-alpha and malondialdehyde,and arterial blood gas analysis was performed simultaneously.Respiratory index and oxygenation index (OI) were calculated,and the occurrence of OI ≤ 300 mmHg was recorded.Results Compared with group C,the serum IL-6 and tumor necrosis factor-alpha concentrations and respiratory index were significantly decreased,and IL-1O concentrations and OI were increased at T1-4,and malondialdehyde concentrations were decreased at T1-3,and the incidence of OI ≤ 300 mmHg was decreased in group Dex (P<0.05).Conclusion Dexmedetomidine can inhibit inflammatory responses and improve the postoperative pulmonary function in patients undergoing laparoscopic operation.
