OBJECTIVETo investigate the method and clinical outcome of reconstructing large pulp defects of the fingertips with a homodigital neurovascular island flap.
METHODSForm June 2007 to October 2009, 16 patients with the defects of pulp were repaired by the spiral flap that was a homodigital neurovascular island flap with a unique spiral advancement and transposition design allowed pulp reconstruction using sensate glabrous skin while restricting donor morbidity to the injured digit. There were 12 males and 4 females with an average age of 37 years ranging from 18 to 49 years. The defect were caused by machine crush injury 11 cases, pressure injury by heavy objects in 2 cases, crush injury by door of car 1 case, injury by saw in 2 cases. The defect was located in the index finger in 5 cases, the middle finger in 9 cases,the ring finger in 2 cases. All injuries had large pulp defects averaging 1.6 cm (long) x 1.2 cm (wide) to 2.5 cm (long) x 1.7 cm (wide). Short-term results for all patients were reviewed. Outcome measures included static 2-point discrimination, total active motion, and hypersensitivity or cold intolerance.
RESULTSAll flaps achieved primary healing with no complications. Sensory recovery was excellent with an average 2-point discrimination of 5.1 mm. All patients were followed-up for 8 to 20 months (averaged 12 months) with highly satisfactory with both aesthetic and functional outcome. There was no hypersensitivity or cold intolerance. According to the evaluation of total active motion (TAM) scales, the results were excellent in 7 cases, good in 8 cases (9 lesions) and fair in 1 case.
CONCLUSIONThe spiral advancement-transposition flap is suitable for resurfacing large pulp defects with excellent short-term functional and aesthetic results and high patient satisfaction.

OBJECTIVETo evaluate the value of flexible fiberoptic bronchoscopy in diagnosis and treatment of pulmonary atelectasis in children.
METHODTotally 104 patients with pulmonary atelectasis, who were admitted to this department, received flexible fiberoptic bronchoscopy from January 2006 to May 2010, were enrolled in a retrospective analysis.
RESULTThe analysis on causes of pulmonary atelectasis showed that 76 cases (73%) of the 104 patients had sputum obstructions, which was the main cause of atelectasis. Thirteen cases (13%) had bronchopulmonary dysplasia, 9 cases among these were infants. Twelve cases (12%) had foreign body aspiration, 8 cases among these were under the age of 3-year. After flexible fiberoptic bronchoscopy, 100 cases got expansion of pulmonary atelectasis. Sixty-five of the sputum obstruction cases got atelectasis reexpansion after one time of flexible fiberoptic bronchoscopy. Eight of the sputum obstruction cases got atelectasis reexpansion after two times of flexible fiberoptic bronchoscopy. Two of the sputum obstruction cases got atelectasis reexpansion after three times of flexible fiberoptic bronchoscopy. The rate of atelectasis reexpansion after one time of alveolus lavement was higher in the cases whose courses of disease were under 3 weeks, than in the cases whose courses of disease were beyond 3 weeks.
CONCLUSIONEtiology of pulmonary atelectasis varied at different age. The morbidity of bronchopulmonary dysplasia was high in infants. Foreign body aspiration was the common cause of pulmonary atelectasis in children from 1 to 3-year of age. Sputum obstruction was the main cause of pulmonary atelectasis in over 3-year-old children. Most cases got atelectasis reexpansion after alveolar lavage. The patients who had shorter course of disease might have higher rate of atelectasis reexpansion after alveolar lavage once. Flexible fiberoptic bronchoscopy plays an important role in diagnosis and treatment of pulmonary atelectasis.

OBJECTIVETo examine how the thymidine phosphorylase (TP) gene expression is upregulated by interferon-alpha (IFN-alpha) in human hepatocellular carcinoma SMMC-7721 cells.
METHODSTP mRNA levels were determined by RT-PCR. Whether the JAK-STAT cascade mediates IFN-alpha-induced TP mRNA expression was studied by pretreatment with Janus Kinase (JAK) inhibitor, AG-490. Effects of IFN-alpha on TP mRNA stability were detected with additional actinomycin D.
RESULTSThe expression of TP mRNA was induced by IFN-alpha in a dose- and time-dependent manner in SMMC-7721 (human hepatocellular carcinoma) cells. TP mRNA levels rose at 8 h, reached the peak value at 12 h, and remained at a high level up to 72 h in SMMC-7721 cells treated with IFN-alpha 10000 U/ml. IFN-alpha at a dose of 5000 or 10000 U/ml up-regulated TP expression about 3 fold compared with that of non-treated cells (P < 0.05). Induction of TP mRNA expression by IFN-alpha was significantly inhibited in SMMC-7721 cells by pretreatment with AG-490, in comparison with that treated with IFN-alpha alone. Pretreatment of SMMC-7721 cells with IFN-alpha 10000 U/ml for 24 h caused a substantial stabilization of TP mRNA, with a half-live of 35.8 h, compared with 8.5 hr in the control SMMC-7721 cells.
CONCLUSIONIFN-alpha at certain doses upregulates TP mRNA expression via both JAK-STAT transcriptional activation and post-transcriptional mRNA stabilization in human hepatocellular carcinoma SMMC-7721 cells.

OBJECTIVETo verify the clinical efficacy on mild cognitive impairment (MCI) treated with electroacupuncture (EA) intervention based on the principle as "promoting the circulation of the Governor Vessel and regulating the marrow" and plan to provide the A-grade evidence of the evidence-based medicine for the clinical treatment of this disease with acupuncture and moxibustion.
METHODSThe multi-center randomized controlled trial (RCT) was adopted. One hundred and ninety-two cases of MCI were randomized into an EA group and a nimodipine group, 96 cases in each one. In the EA group, EA was applied to Shenting (GV 24), Baihui (GV 20), Sishen cong (EX-HN 1) and Fengchi (GB 20), once every other day. In the nimodipine group, Nimodipine was pre scribed for oral administration. Four weeks constituted one course, the treatment of 8 weeks was required. The minimum mental state examination (MMSE) and the graphic recognition test (GRT) were applied before and in the 1st and 2nd session of treatment separately. The follow-up visit of MMSE scale was provided in the 1st, 3rd and 6th months after treatment separately.
RESULTSThe total effective rate was 50.0% (47/94) in the EA group, which was superior to 34.4% (32/93) in the nimodipine group (P < 0.05). At the end of the 1st session treatment, the differences in MMSE total score and the cognitive, memory and speech dimensional scores were not significant statistically between two groups (all P > 0.05). At the end of the 2nd session treatment, the MMSE total score and the cognitive, memory, visual-space skill dimensional scores were improved in comparison before treatment (all P < 0.05). The results in the EA group were superior to those in the nimodipine group (all P < 0.05). But the difference in the speech dimensional score was not significant statistically between the two groups (P > 0.05). In the EA group, the GRT score was improved significantly after 2 sessions of treatment as compared with that before treatment (P < 0.01) and was superior to that in the nimodipine group (P < 0.05). In the 1st, 3rd and 6th month after treatment, the MMSE scale total scores were different significantly in statistics between the two groups (all P < 0.01). The long-term efficacy in the EA group was superior to that in the nimodipine group.
CONCLUSIONBoth of the EA therapy based on the principle as "promoting the circulation of the Governor Vessel and regulating the marrow" and the nimodipine program improve significantly the cognitive function of MCI patients. Compared with the nimodipine program, the EA therapy improves the comprehensive cognitive and the short-term memory abilities much more significantly and is especially advantageous at improving cognitive, memory and visual-space skill dimensions for MCI patients. In the half a year follow-up visit after the end of treatment, the long-term efficacy of EA is better than that of Nimodipine.

OBJECTIVETo investigate the association of calcitonin receptor (CTR) gene polymorphism with bone mineral density (BMD) in premenopausal and postmenopausal women.
METHODSCTR genotypes were determined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) in 184 premenopausal women and 199 postmenopausal women in Shanghai area. BMD at lumbar spine (L2-4) and femoral neck (FN) were measured by dual-energy X-ray absorptiometry (DEXA).
RESULTSThe distribution of CTR genotypes in 383 Shanghai women were CC genotype 83.8%, TC genotype 14.6%, TT genotype 1.6%, respectively. BMD at FN of CC genotype was significantly higher than TC and TT genotypes (P < 0.01) in postmenopausal women. But there was no difference in BMD of different CTR genotypes in premenopausal women. Multiple regression analysis showed that CTR genotypes were associated with FN BMD in postmenopausal women (P < 0.05).
CONCLUSIONSThe polymorphism of CTR gene was associated with BMD in postmenopausal women.

OBJECTIVETo investigate the relative contribution of fat mass and lean mass on bone mineral density (BMD) in premenopausal healthy women.
METHODSThe BMD at lumbar spine, proximal femur and total body, together with fat mass and lean mass was determined by dual-energy X-ray absorptiometry (DEXA), the body height, weight, waist, and hip circumference were also measured, and body mass index (BMI) and waist-hip ratio were calculated in 282 premenopausal women.
RESULTSFat mass was a major determinant for BMI, BMI and lean mass were positively related with L2-4, proximal femur and total body BMD (P = 0.000 for all), and lean mass were the only independent factor contributing to L2-4 (standardized coefficient beta = 0.282, P = 0.000), proximal femur (beta = 0.336, P = 0.000) and total body BMD (beta = 0.361, P = 0.000) in stepwise regression analysis. The relationship between BMI and BMD was further improved after controlling fat mass, while decreased or even lost when controlling lean mass.
CONCLUSIONSLean mass was an important factor determining BMD in premenopausal women.

OBJECTIVETo analyze the serum total cholesterol level and the prevalence of hypercholesterolemia and borderline high cholesterolemia among urban-resident adults in China from 2010 to 2012.
METHODSData were from Chinese Nutrition and Health Surveillance in 2010-2012. Multi-stage stratified proportion to the population cluster random sampling method was conducted to determine 54 042 adult residents in 34 big cities and 41 small and medium-sized cities. Serum total cholesterol was measured by cholesterol oxidase method. Hypercholesterolemia and borderline high cholesterolemia were evaluated by Guidelines on Prevention and Treatment of Blood Lipid Abnormality in Chinese Adults 2007 edition. Standardized cholesterol level (x ± Sx) and prevalence of hypercholesterolemia and borderline high cholesterolemia were calculated through weighted complex sampling processing by population data released by the National Bureau of Statistics in 2009.
RESULTSThe mean level of urban-resident adults's erum total cholesterol was (4.58 ± 0.05)mmol/L, (4.58 ± 0.05)mmol/L for both male and female. The cholesterol concentration level in big cities and small and medium-sized cities were (4.66 ± 0.04)mmol/L and (4.57 ± 0.06) mmol/L, respectively. It increased with age gradually from the minimum level, which was (4.18 ± 0.05)mmol/L in aged 18 to 29 group, till reached the maximum, which was (4.94 ± 0.05)mmol/L in aged 60 to 69 group, and then it declined to (4.92 ± 0.06)mmol/L in aged 70 group. The prevalence of hypercholesterolemia and borderline high cholesterolemia were 5.6%(95%CI:4.5%-6.6%) and 24.7%(95%CI:21.6%-27.9%) totally; 5.1% (95%CI:4.1%-6.1%) and 24.4% (95%CI:21.0%-27.6%) for male, 6.0% (95%CI:4.7%-7.3%) and 25.1%(95%CI:21.8%-28.4%) for female; 6.0%(95%CI: 5.0%-7.0%) and 27.7%(95%CI:24.9%-30.6%) in big cities, while 5.5%(95%CI: 4.2%-6.7%) and 24.2%(95%CI:20.5%-27.9%) in small and medium-sized cities. The minimum prevalence of hypercholesterolemia was in aged 18 to 29 group and maximum in aged 70 group, which were 2.2%(95%CI: 1.4%-3.0%) and 10.3%(95%CI: 7.1%-13.4%), respectively; while the lowest borderline high cholesterolemia prevalence was in aged 18 to 29 group and the highest in aged 60 to 69 year group, which were 12.9%(95%CI: 10.4%-15.4%) and 37.6% (95%CI: 33.6%-41.6%), respectively.
CONCLUSIONThe serum total cholesterol level and the prevalence of hypercholesterolemia and borderline high cholesterolemia were high among urban adults in China from 2010 to 2012, and more attention should be paid for high serum total cholesterol level among older adults.
