Objective To detect the mutations of ATP2C1 gene in patients with Hailey-Hailey dis- ease (HHD).Methods PCR and direct sequencing were performed in 17 patients and 120 healthy controls to screen the mutations in the exons of ATP2C1 gene.Results Eight mutations were identified in nine probands, including three deletion mutations (nt1464-1487 del/nt1462-1485del,1523delAT,2375delTTGT),three splice site mutations (360—2A→G,1415—2A→T,2243+2T→C) and two missence mutations (C920T and G1942T).None of the above mutations was found in the controls.Conclusion Eight specific novel mutations were identified in nine probands of HHD,which could be causative factors of the disease.

Objective To observe the anatomic and imaging morphology ofjugnlar bulb and its relationship with the surrounding structures, and to investigate the classification ofjugnlar bulb and its clinical significance. Methods We dissected 30 human temporal bones and studied multi-slice spiral CT imaging data of temporal bone of 120 cases and blood vessel cast mould specimen of the jugular bulb of 6 cases, to observe the morphology of jugnlar bulb and its spatial relationship with the surrounding structures. We made an imagined sagittal plane on the medial well of the tympanic cavity, with a horizontal tangent line of the proximal wall of the tympanic cavity and a vertical tangent line of the posterior wall of the tympanic cavity as coordinate axes (X axis and Y axis), respectively, so the 4 quadrants ( Ⅰ , Ⅱ, Ⅳ, Ⅳ) were formed. The jugular bulb was classified intro 4 types according to the quadrant where its top was projected and subtyped according to its position on the inner or outer side of the plane. The operation via mastoid approach was simulated on specimen to observe the effect of jugnlar bulb on the operation route. Results Some jugular bulbs were flat type and others were prominent types. The classification in the group of CT image: type Ⅰ , 11 case (9%);type Ⅱ, 63 cases (53%);type Ⅲ, 25 cases (21%);type Ⅳ, 21cases (17%). The classification in the group of specimen: type Ⅰ, 1 case (3%);type Ⅱ, 11 cases (37%);type Ⅲ, 8 cases (27%);type Ⅳ, 10 cases (33%). Each type of the jugular bulb had different effects on the operative approach. Conclusions The classification method with the 4 quadrants is a simple and three-dimensional way to describe the position of the jugular bulb for imaging diagnosis or operative scheme design.

OBJECTIVETo investigate the biological characters of human skin fibroblasts in fibroblast populated collagen lattice (FPCL).

METHODSThe human fibroblasts were cultured in 3D and the collagen of the rat tail was also prepared. They were examined with the comprising cell cycle and apoptosis, mRNA expression of TGF beta1, and fibronectin, and cell morphology.

RESULTSThe flow cytometry showed that the G0/G1, stage cells were 79% +/- 3%, 87% +/- 2% after the 7 days and 14 days separately, and there were not apoptosis peak observed. RT-PCR analysis revealed that the mRNA expression of TGF beta1, and fibronectin had no difference between human skin fibroblasts cultured in 3D and 2D. Electron microscope showed the cells were plenty of chromatin and organelles.

CONCLUSIONSThe proliferation of the human skin fibroblasts in FPCL is slow, but its biological viability is better.

OBJECTIVETo evaluate the efficacy of sublingual immunotherapy (SLIT) with dermatophagoides farinae drops in patients with allergic rhinitis (AR).

METHODSTwo hundred and six patients with AR aged from 4 to 60 years were included in this study. Among them, 123 patients completed more than one year treatment, the number of patients completed one year, one year and a half, two years were 61, 41, 21 cases. Rhinitis symptom scores and medication scores of the three groups before and after treatment were compared. And rhinitis symptom scores and medication scores of patients with one year drug withdrawal after one and two years treatment were aslo compared.

RESULTSAfter SLIT one year, one year and a half, two years treatment, the symptoms in these patients were significantly improved compared with before. The symptom scores (x±s) were reduced from 6.00±2.27, 7.39±1.99 and 6.29±2.14 to 2.95±1.82, 3.28±2.58, 2.48±1.99. The differences were statistically significant (t value was 8.19, 10.29, and 5.97, all P<0.01). The proportion of patients without drug treatment of the three group were 68.9%, 73.2% and 80.9%, there was statistical significance before and after treatment in every group (value was 50.391, 43.619, 27.776, all P<0.01). Symptom improvement of sneezing, runny nose, nasal congestion, nasal itching were similar after one year, one year and a half, two years SLIT treatment, the differences were not statistically significant (F values were 1.200, 1.276 and 2.333, all P>0.05). The proportion of patients without drug treatment in the group which stopped medication one year after two year SLIT (76.2%) was higher than group stopped medication one year after one year SLIT (61.3%). There was no statistical significance (χ2=1.263, P>0.05).

CONCLUSIONThe dust mite drops can relieve symptoms after one year treatment, but the proposed two years treatment is important for the consolidation of improved symptoms, especially for the effect of reducing the use of symptomatic medication.

OBJECTIVETo investigate the effects of Bushen Huoxue Fang (BSHX) on the apoptosis of epithelial cells in the prostatic ductal system of rats with benign prostatic hyperplasia (BPH) and its possible action mechanism.

METHODSOne hundred 3- month-old male Wistar rats were randomly divided into four groups of equal number (control, castrated, BPH model, and BSHX). BPH models were made by subcutaneous injection of testosterone following castration; the rats in the BSHX group were treated intragastrically with BSHX at 2.34 g/ml after modeling, while those in the other two groups with equal volume of saline, all for 37 days. On the 38th day, all the rats were sacrificed and their prostates harvested for detection of the distribution of TGF-beta1 and alpha-actin and the count of positive cells in the prostatic ductal system by immunohistochemical staining. The apoptosis rate of epithelial cells in the prostatic ductal system was determined by TUNEL assay.

RESULTSThe expression of TGF-beta1 was significantly increased in the rats of the BSHX group as compared with the BPH models in both the proximal prostatic duct ([15.28 +/- 4.30]% vs [36.42 +/- 8.10]%, P < 0.01) and the distal prostatic duct ([4.42 +/- 2.07]% vs [8.71 +/- 2.28 ]%, P < 0.05), while the expression of alpha-actin in the proximal duct was remarkably higher in the BSHX-treated rats than in the models ([28.14 +/- 7.43]% vs [18.28 +/- 4.07]%, P < 0.01), but lower than in the control animals ([33.57 +/- 6.85]%, P < 0.05). Compared with the control group, the BPH models and BSHX-treated rats both exhibited markedly decreased apoptosis of epithelial cells in the proximal prostatic duct ([39.42 +/- 9.20]% vs [3.86 +/- 1.34]%, P < 0.01, and [31.14 +/- 5.64]%, P < 0.01) and distal prostatic duct ([17.60 +/- 4.86]% vs [3.07 +/- 1.14]%, P < 0.01, and [12.37 +/- 2.25]%, P < 0.05). The apoptosis rate of epithelial cells in the prostatic ductal system was significantly higher in the BSHX-treated rats than in the BPH models (P < 0.01).

CONCLUSIONBy upregulating the expression of TGF-beta, BSHX can suppress the reduction of smooth muscle cells in the proximal prostatic duct, promote the apoptosis of prostatic epithelial cells, and thus effectively inhibit benign prostatic hyperplasia.

OBJECTIVETo investigate the relationship between insulin resistance and carotid atherosclerosis in patients with potential hyperglycemia.

METHODSA total of 221 patients were recruited among those with potential hyperglycemia. All participants underwent physical examination, medical history interview, and 75 g oral glucose tolerance test. Venous blood was sampled for measurement of insulin and cholesterol levels. The intima-media thickness (IMT) in bilateral common carotid arteries was observed by B-mode ultrasound. Insulin resistance index was calculated by homeostasis model assessment (HOMA-IR). Subjects were stratified in quintiles according to HOMA-IR values. Risk factors and atherosclerotic parameters were analyzed.

RESULTSWith HOMA-IR value increase, incidence of impaired glucose tolerance, diabetes mellitus, hypertension, and coronary artery disease increased, the levels of triglyceride (TG), low density lipoprotein cholesterol (LDL-C), fasting plasma glucose, 2 hour plasma glucose, and fasting insulin increased as well, while the level of high density lipoprotein cholesterol (HDL-C) decreased. Meanwhile, all atherosclerotic parameters increased. Multivariate regression analysis showed that TG, total cholesterol, HDL-C, LDL-C levels, and ln(HOMA-IR) were related to IMT, hence were risk factors for IMT increase.

CONCLUSIONInsulin resistance is implicated in atherogenesis.

OBJECTIVETo evaluate the incidence of postoperative hemorrhage in children undergoing adenoidectomy, and to discuss its possible causes.

METHODSIncluded in this study were children who underwent adenoid and/or tonsil surgery at Shenzhen Children's Hospital between January 2004 and November 2009. The change of hemoglobin (Hb) and hematocrit (Hct) were retrospectively analysed. The blood loss was estimated by the change of Hct.

RESULTSThere were 2078 cases that accomplished the inclusion criteria in the period of study. Ten children bled 0.5 - 4.0 hours after surgery, without superfluous hemorrhage during the operation and post-tonsillectomy. This represented an incidence of 0.48%of immediate postoperative haemorrhage among the 2078 procedures analyzed. Statistical differences were found between boys (0.21%) and girls (1.10%, χ² = 5.597, P < 0.05). The change of Hb and Hct was positively correlated (r = 0.95, P < 0.01), the blood loss was positively correlated with the bleeding time (r = 0.66, P < 0.05). The causes of postoperative hemorrhage were coagulation system deficits, chronic nasopharyngitis, deficient hemostasis and immoderate ravage. To control the postoperative hemorrhage, 2 postnasal packing under topical anaesthesia and 8 electrocautery under general anaesthesia were applied.

CONCLUSIONSPoor operative technique and deficient hemostasis are the major causes of primary hemorrhage. Prompt operation to control the postoperative bleeding should be done 2 hours after bleeding under general anesthesia in order to avoid severe complications.
