OBJECTIVETo recognize the clinical features of the bronchiolitis obliterans.

METHODClinical manifestation, chest X-ray, computed tomography (CT) and pulmonary function of 4 cases with bronchiolitis obliterans were retrospectively analyzed.

RESULTTwo cases were after Stevens-Johnson syndrome (SJS), the other 2 were after severe pneumonia, including one suffered from adenovirus pneumonia. Cough, tachypnea and wheezing persisted in all the 4 patients. The symptoms lasted for at least 6 weeks, in one case for over one year. Crackles and wheezing were present in all the 4 cases. Hyperinflation was seen in chest radiographs in all cases. On pulmonary CT/high-resolution CT (HRCT), patchy opacity and bronchial wall thickening were seen in each patient. Areas of air trapping were seen in three cases. Bronchiectasis was seen in 2 cases, atelectasis and mosaic perfusion were seen respectively in one case. PO(2) was low in all the four cases. Wheezing was not responsive to beta(2) agonist and other bronchodilating therapy. Prednisone was used at a dose of 1 mg/(kg.d) in 3 cases. Two cases were followed up for 3 months. The clinical condition of one case was improved, whose wheezing and bronchiolar constriction disappeared, cough and dyspnea were also relieved. However, the condition of one patient was not improved, although the wheezing disappeared. The HRCT of these two cases showed no improvement.

CONCLUSIONClinical symptoms of BO were cough, tachypnea, and wheezing after acute lung injury. Crackles and wheezing were the most common signs in the BO. Chest radiographs showed hyperinflation. Pulmonary CT showed bronchial wall thickening, bronchiectasis, atelectasis, and mosaic perfusion. Pulmonary function tests suggested obstruction of small airway.

OBJECTIVETo explore the reliability and validity of digital pulse wave analyzing method in evaluating arterial compliance in population-based study.

METHODSAll 415 adults (132 men and 283 women) aged 20 to 86 years old were selected from urban (220 persons) and rural (195 persons) areas, respectively by a stratified randomly sampling method. Arterial compliance, evaluated by stiffness index (SI), was measured by using digital pulse wave analyzing method from the Pulse trace machine (Micro medical, London), and the SI value was determined accordingly.

RESULTSIn the study on both repeatability and stability, there was a perfect correlation between the frequent measurements for one individual either on one occasion or on two 40-days-apart occasions. The SI values were not significantly different between the urban and the rural, men and women. Multiple stepwise regressions showed that systolic blood pressure and age were positively correlated with SI value, respectively (both P values were less than 0.001). The correlation kept unchanged after taking account of gender, BMI and heart rate. The mean SI values for people aged 20 to 29, 30 to 39, 40 to 49, 50 to 59 and > or = 60 were 7.35, 8.84, 10.41, 10.95 and 12.01 m/s (P < 0.01), respectively.

CONCLUSIONSBoth systolic blood pressure and age should be contributed as the main influencing factors of arterial compliance. Digital pulse wave analyzing method is a preferable measurement in evaluating arterial compliance in population-based study due to its better repeatability and stability.

Methods In vitro fertilization of Mongo?lian gerbil was performed with the self?prepared capacitation solution and semen, and the 2?cell embryos of Mongolian ger?bils were cultured in vitro using an improved KSOM culture medium. Results The in vitro fertilization rate of gerbils was over 60%, and some gerbil 2?cell embryos could develop further in vitro. Conclusions An in vitro fertilization and embry?o development system of Mongolian gerbil has been established, but it needs further optimization.

OBJECTIVEGenetic factors are thought to be involved in the development of vitiligo. The aim of this study is to explore the possible genetic model of vitiligo by analyzing the genetic characteristics of 815 patients from Zhejiang province.

METHODSData for 815 patients with vitiligo together with their first- and second-degree relatives were obtained using a standardized questionnaire. All these information was requested to confirm the answers about family history in order to reduce the possibility of 'recall' bias. The 815 probands would include 411 (50.43%) males and 404 (49.57%) females with a varied age from 2 months to 71 years old. Since the information on general prevalence of vitiligo in this area was absent, a control group was set up to facilitate the calculations of heritability degree. 468 persons of the control group were from non-vitiligo population with a sex ratio of 241(male): 227(female) with varied age of 4 months to 80 years old. Both gender and age were comparable between the vitiligo and the control population. The inheritance pattern estimation, heritability calculation and complex segregation analysis were performed with Penrose method, Falconer regression method and SAGE-REGTL program.

RESULTSIn 815 vitiligo probands, 128 had and 687 had not family histories, with a heritability rate of 15.7%. The vitiligo prevalence in proband's first degree relatives was 2.580%, higher than the prevalence of 0.618% in second degree relatives, and both of them were higher than general prevalence: 0.192%. By Penrose method, the rates on different catagories were as follows: sibling prevalence rates s = 0.080 18; population prevalence rate q = 0.001 92; s/q = 41.76. The ratio of s/q did not approach 1/2q (260.42) or 1/4q (130.21), but approached 1/square root of q(22.82), suggesting vitiligo was consistent with a mode of polygenic inheritance. Using Falconer's method, heritabilities of vitiligo in first-and second degree relatives of probands were 59.61% (95% confidence interval 65.37-53.84) and 55.20% (95% confidence interval 43.88-66.52), respectively. The weighted average of heritability in all relatives was 58.7% (95% confidence interval 53.56-63.83). The results of complex segregation analysis suggested that major gene model including the Mendelian dominant, recessive and additive hypotheses were not rejected (P > 0.05). Purely environmental model and no transmission model were rejected at a 0. 001 significance level. According to AIC, Mendelian dominant inheritance was the best-fitted hypothesis.

CONCLUSIONGenetic factors played an important role in the occurrence of vitiligo, and the genetic model of vitiligo could serve as the polygenetic or multifactorial inheritance with major gene trait.

OBJECTIVETo evaluate the therapeutic effect of retained copper wires combined with pingyangmycin (PYM) injection for complicated cavernous venous malformation.

METHODSThe location of venous malformation was detected by physical examination and MRI. The copper wires in 0.2 mm width were used to puncture the lesion repeatedly and retained in the lesion to form a net. After that, 8 mg PYM was injected into the residue malformed veins. 8-10 days later, the copper wires were taken out and necrotic tissue was squeezed out. The wounds of punctual holes healed through dressing. The patients received postoperative MRI to evaluate the therapeutic effect.

RESULTSFrom Jan. 2002 to Dec. 2008, 45 cases were treated. The patients were followed up for 1-3 years. 51.1% (23/45) of the lesions shrinked markedly or even disappeared. 42.2% (19/45) of the lesions reduced. 6.67% (3/45) of the lesions didn't change. There was no complication like invasive infection.

CONCLUSIONSIt is very effective to treat complicated cavernous venous malformation with retained copper wires combined with pingyangmycin injection.

AIM To prepare and characterize SiO2 solid dispersions of Curcumae longae Rhizoma extract.METHODS For the solid dispersions prepared by solvent evaporation method,its ratio of extract to carrier (SiO2) was screened by in vitro dissolution test,and the characterization was achieved by determination of particle size,specific surface area,porosity,micromorphology observation,infrared spectroscopy and X-ray.RESULTS When the ratio of extract to carfer was 1:8,three main components (bisdemethoxycurcumin,demethoxycurcumin and curcumin) in the extract reached the highest accumulative dissolution rates.Compared with physical mixture,the solid dispersions demonstrated lower particle size,specific surface area and porosity.Extract was dispensed in the carrier in an amorphous state.CONCLUSION SiO2 solid dispersions can obviously improve the dissolution rates of the main components in Curcumae longae Rhizoma extract.

Objective To investigate the role of microRNA-10b (miR-10b) in the proliferation and invasion potential of osteosarcoma cell lines MG-63 and the exact underlying mechanism.Methods The expression level of miR-10b in human osteosarcoma tissue samples and adjacent normal bone tissues were detected by relative quantitative real-time PCR (qRT-PCR).miR-10b mimic and siRNA against Twist (Twist siRNA) were transfected into human osteosarcoma cell lines MG-63 respectively using lipofactamine 2000, and RT-PCR was used to detect the mRNA expression levels of miR-10b and Twist, and Twist protein expression level was detected by Western blot.The effect of miR-10b mimic and Twist siRNA on proliferation of MG-63 were detected by MTT[3- (4, 5-dimethylthiazol-2-yl) -5- (3-carboxymethoxyphenyl) -2- (4-sulfophenyl) -2 H-tetrazolium].The in-vitro cell invasion ability was determined by Transwell invasion assays after up-regulating miR-10b or knocking down of Twist.Results The expression levels of miR-10b was higher in human osteosarcoma tissue samples compared with adjacent normal bone tissues, the differences were extremely statistical significance (P＜0.01).miR-10b directly up regulated the mRNA and protein expression levels of Twist, the differences were significant (P＜0.05).In addition, miR-10b had enhanced the cell invasion and the proliferation (P＜0.05), whereas the proliferation and invasion ability of MG-63 which transfected by both miR-10b mimic and Twist siRNA were significantly reduced than that transfected by miR-10b mimic (P＜0.05).Conclusion miR-10b in MG-63 promotes the proliferation and invasion potential of human osteosarcoma cell lines MG-63, at least partly through the upregulation of Twist gene.
