OBJECTIVETo review and investigate the optimal preoperative diagnostic means and treatment principles of hepatic angiomyolipoma (HAML).

METHODSThe clinical features, treatment, prognostic and follow-up data of 169 HAML patients treated between January 1992 and May 2010 were retrospectively analyzed. The median age of the patients, including 46 male and 123 female (male/female, 1/2.7), was 45 years (range, 17 - 73 years). The mean case history was 0.54 year with a range of 2 d to 16 years.

RESULTSAmong the 169 patients, 149 patients (88.2%) had a solitary tumor and 96 patients (56.8%) were detected in the right lobe. The overall preoperative diagnostic rate was 13.6% and 119 patients (70.4%) were misdiagnosed as hepatocellular carcinoma or hepatic cavernous hemangioma. The diagnostic accuracy of MRI is higher than CT in distinguishing the nature of the tumor (χ² = 5.508, P = 0.019). One hundred and sixty-eight patients received surgical resection and one received percutaneous microwave coagulation therapy. One patient occurred postoperative hemorrhage and 3 patients developed hydrothorax. The postoperative mortality and recurrence for all the patients were 0. Postoperative pathology confirmed the diagnosis of hepatic angiomyolipoma. Follow-up study showed a benign course and no signs of recurrence.

CONCLUSIONSMRI is the main diagnostic means of HAML. Treatment strategies of HAML depends largely on tumor size, location and growth rate. Surgical management is suggested to patients with the following criteria: (1) tumor size greater than 5 cm; (2) with clinical symptoms; (3) faster tumor growth; (4) the tumor located at 1, 4, 5, 8 segments of liver.

OBJECTIVETo investigate the protective effect of inhibition of stress (lytic cocktail) on lung injury in severe burn rats at early stage.

METHODSSprague-Dawley rats inflicted with 30% TBSA full-thickness burn were randomly divided into A group (n = 36, fluid resuscitation with administration of lytic cocktail), B group (n = 36, fluid resuscitation only). Lung function was evaluated by partial pressure of oxygen (PaO2) in arterial blood and histopathologic changes on 3, 5, 7, 10 post burn day (PBD). The levels of malonyldialdehyde (MDA), myeloperoxidase (MPO), tumor necrosis factor-alpha(TNF-alpha) and interferon-gamma (IFN-gamma) in lung tissue were measured at the same time points.

RESULTSThe PaO2 level in A group on 3 PBD (12.58 +/- 0.41 kPa) was significantly higher than that in B group (8.86 +/- 0.23 kPa, P < 0.01). Compared with those in B group, the levels of MDA and MPO were significantly decreased in A group at each time point (P < 0.05 or 0.01), the levels of TNF-alpha on 3, 5, 7 PBD (P < 0.05 or 0.01) and IFN-gamma on 5, 7, 14 PBD (P < 0.01) were also decreased in A group. Swollen lung mesenchyme was alleviated, infiltration of inflammatory cell was lessened in A group.

CONCLUSIONLytic cocktail combined with immediate fluid resuscitation can inhibit stess response, downregulate the expression of inflammatory factor, ameliorate lung function in severe burn rat at early stage.

OBJECTIVETo probe into the clinical effect of needle-pricking therapy for treatment of polycystic ovarial syndrome.

METHODSOne hondred and twenty-one cases of polycystic ovarial syndrome were divided into a needle-pricking therapy group of 61 cases and a medication group of 60 cases with randomized and controlled method. The needle-pricking therapy group were treated by needle-pricking therapy at sacral plexus stimulating points on both sides of the spine and lateral points of Dazhui (CV 14), and the medication group by oral administration of domiphen and intramuscular injection of chorionic gonadotropin (HCG). Levels of hormones and symptoms in the patients before treatment, after treatment of 3 cycles and at the sixth cycle after treatment were investigated.

RESULTSAfter treatment of 3 cycles, the level of hormone and B type ultrasound examination were significantly improved in the two groups (P < 0.01). At the sixth cycle after treatment, the conditions of the patients in the medication group were returned to the original levels before treatment, while the conditions in the needle-pricking therapy group still kept at the post-therapeutic level, and their menstruation and ovulation restored to normal state, and the ovulation mucosa and the pregnancy rate were significantly higher than those in the medication group (all P < 0.01).

CONCLUSIONNeedle-pricking therapy has obvious effect on polycystic ovarial syndrome, and has a good long-term therapeutic effect.

OBJECTIVETo investigate the biological characteristics of dermal fibroblasts of the diabetic rats with deep partial thickness scald, and to explore its relationship with delayed wound healing due to diabetes.

METHODSSprague-Dawley rats weighing 250 g were randomly divided into control (NM, n=40) and STZ-induced diabetic (DM, n=50) groups, and then deep partial thickness scald involving 10% TBSA were reproduced in the two groups. Skin samples were harvested from the wounds on 0, 3, 7, 14 and 21 post scald day (PSD) for the determination of certain histological characteristics.

RESULTSThe thickness of dermis layer in DM group before injury was obviously thinner than that in NM group (P < 0.01). There was an infiltration of a large amount of chronic inflammatory cells and increased content of cutaneous glucose in the dermal tissue in DM group (2.77 mg/g) compared with 0.85 mg/g in NM group, (P < 0.01). An accumulation of advanced glycation end products (AGEs) was found in the dermal tissue in DM group. After the scalding, the percentage of fibroblasts in S phase and hydroxyproline synthesis in DM group was evidently lower than those in NM group. But the apoptosis rate of fibroblasts was much higher in DM group than that in NM group (P < 0.05 or 0.01).

CONCLUSIONIt is found that the high contents of glucose and AGEs in diabetic skin exert untoward effects on biological characteristics of dermal fibroblast, probably constituting one of the underlying mechanisms of delay wound healing of scald in diabetic rats.
