Objective To explore the relationship between lung function and bone mineral density (BMD) in nonsmoking women. Method The healthy women who came to our hospital for physical examination from June 2013 to March 2014 were chosen. Totally 508 cases, average age 49.33±8.66 years , were included through the questionnaire and further examination. The lumbar BMD was measured with dual energy X-ray absorption, the subjects were divided into normal bone mass group, osteopenia group, and osteoporosis group according to the diagnostic criteria of WHO. Through questionnaires, the human body composition analyzer, pulmonary function test apparatus were used to acquire their general information, body mass index (BMI) and pulmonary ventilation function. The data were compared by analysis of variance, Pearson correlation analysis and multiple linear stepwise regression analysis were applied to explore the relationship among the pulmonary ventilation function and bone mineral density of lumbar spine and lumbar bone area (BA). Result BMI, forced vital capacity rate of one second (FEV1/FVC) were not significantly different among the three groups (F values were 0.192, 0.296;All P>0.05);the other indicators of pulmonary function including forced vital capacity (FVC),FVC percent predicted (FVC%), forced expiratory volume in first second(FEV1), FEV1 percent predicted(FEV1%),peak expiratory flow rate(PEF)decreased markedly in osteoporosis group compared with normal group and osteopenia group (F=15.313, 5.508, 18.890, 5.440, 6.763;all P<0.05). The lumbar spine BMD and lumbar BA declined significantly in osteoporosis group and osteopenia group comparing with normal group(F=169.053, 205.660, 224.567, 201.086, 276.927, 3.550;all P<0.05). Pearson correlation analysis showed that FVC, FVC%, FEV1, FEV1%, PEF were negatively correlated with age (all P<0.01);FVC, FVC%were negatively correlated with BMI (all P<0.05) , FEV1/FVC was positively correlated with BMI P<0.05);FVC was positively correlated with lumbar BMD and lumbar BA (P<0.01). FEV1 were positively correlated with lumbar BMD and lumbar BA(all P<0.01). Multiple regression showed that age, BMI, and lumbar BA were correlated with FVC, FVC%, FEV1, FEV1/FVC(All P<0.01). Conclusion In healthy nonsmoking women, age, BMI, and lumbar BA are the main influencing factors of pulmonary function;except for FEV1/FVC, the other indicators of pulmonary function decreased markedly in osteoporosis group.

Objective To compare the curative effects between minimally invasive and standard direct approach of pri?mary total hip arthroplasty (THA) in elderly patients. Methods One hundred and eighteen geratic patients with hip disease were divided into minimally invasive group (n=61) and standard group (n=57). All the patients were followed up from 15 months to 3 years. The length of incision, surgical duration, intraoperative blood loss, postoperative drainage, number of blood transfusion, hospitalization time and the Harris hip scores were compared between two groups. Results The length of incision, intraoperative blood loss, postoperative drainage, number of blood transfusion and hospitalization time were signifi?cantly lower in minimally invasive group than those in standard group, but the Harris hip scores were significantly higher 3 months after the operation in minimally invasive group than those in standard group (P<0.05). First intention wound healing was found in all patients in two groups. The postoperative complications were significantly lower in minimally invasive group than those in standard group (3.28%vs 15.79%, P<0.05). Conclusion Compared with standard incision of primary total hip arthroplasty , minimally invasive direct lateral approach has its advantages, including small surgical trauma, less hospitaliza?tion time, fewer complications, and which can help restore joint function quickly, making the curative effect satisfied in elderly patients.

Objective To investigate the therapeutic effects of varied operative for the treatment of intrahepatic bile duct stones.Methods The clinical data of 176 consecutive cases of hepatolithiasis surgically treated in the past 3 years in our hospital were retrospectively analyzed.There were 45 type Ⅰ patients,25 type Ⅱ a patients,25 type Ⅱ b patients,3 type Ⅱ c patients,52 type Ea patients,19 type Eb patients,and 7 type Ec patients.These 176 patients were divided into 4 groups according to modus operandi:choledocholithotomy and T-tube drainage in 71 patients (type Ea 31 patients,type Ⅰ 15 patients,type Ⅱ a 25 patients) ; choledocholithotomy and choledochojejunostomy in 25 patients (type Ea 14 patients,type Eb 7 patients,type Ec 4 patients) ; choledocholithotomy and hepaticojejunostomy in 10 patients (type Ⅱb 5 patients,type Ⅱ c 3 patients,type Ea 2 patients) ; hepatectomy plus T-tube drainage or choledochojejunostomy in 70 patients (type Ⅰ 30 patients,type Ⅱ b 20 patients,type Ea 5 patients,type Eb 12 patients,type Ec 3 patients).The postoperative residual stone rate,perioperative complications and long term results were compared between groups.Results Patients undergoing hepatectomy have less postoperative residual stone rate,higher rate of good long term efficacy as compared with those who did not undergo hepatectomy (17.1％ (12/70) vs 43.4％ (46/106),91.4％ (53/58) vs 77.0％ (67/87)).Though patients undergoing hepatectomy had higher rate of perioperative complications (37.1％ (26/70) vs 14.2％ (15/106)).Conclusions Hepatectomy is the most effective procedure for the treatment of type Ⅰ and type Ⅱ b hepatolithiasis.Hepaticojejunostomy is the main procedure for the treatment of type Ⅱ c hepatolithiasis.

Objective To evaluate the necessity of concomitant bladder cuff and the possibility of distal ureter sparing surgery during radical nephroureterectomy of low-level upper urinary tract tumors. Methods Clinical data of 73 patients with low-level (Tis-T3 M0 N0 ) tumors of the proximal upper urinary transitional epithelial cancer treated in radical nephroureterectomy in our hospital from 2000 to 2007 were analyzed retrospectively. The medical charts and pathologic specimens of 35 patients with, and 38 patients without, concomitant bladder cuff were reviewed. Results In the 35 patients with concomitant bladder cuff resection, 8 cases (22.9%) recurrence was observed; in the 38 patients without concomitant bladder cuff resection, 8 cases (21.1%) recurrence was observed. There was no difference between both groups(P>0.05). In the 19 patients suffered renal pelvis tumors with concomitant bladder cuff resection, 4 cases (21.1%) recurrence was observed; In the 16 patients suffered ureter tumors with concomitant bladder cuff resection, 4 cases (25 %) recurrence was observed.There is no difference between patients of renal pelvis tumors and of ureter tumors with concomitant bladder cuff(P>0.05). In the 27 patients suffered renal pelvis tumors without concomitant bladder cuff resection, 3 cases (11.1 %) recurrence was observed; in the 11 patients suffered ureter tumors with concomitant bladder cuff, 5 cases (45.5%) recurrence was observed. There was significant different between patients of renal pelvis tumors and of ureter tumors without concomitant bladder cuff (P<0. 05). Conclusion Concomitant bladder cuff resection confers a favorable prognosis to the patients with ureter tumors, but not to the patients with renal pelvis tumors.

AIM:To investigate the effects of peroxiredoxin 4 ( Prdx4) protein expression levels on the migra-tion and invasion of human cervical cancer HeLa cells.METHODS:The plasmid pcDNA3.0-HA-Prdx4 was transfected into HeLa cells.The HeLa cells were infected with LV-Prdx4 RNAi vector to establish stable Prdx4 shRNA HeLa cells. The change in the expression of Prdx4 protein was validated by Western blotting.The wound-healing assay, and Transwell migration and invasion assays were performed to detect the migration and invasion of HeLa cells, respectively.RESULTS:The expression of Prdx4 protein was up-regulated in the HeLa cells after transfection with pcDNA3.0-HA-Prdx4 plasmid ( P<0.05), whereas it was down-regulated in the Prdx4 shRNA HeLa cells (P<0.05).The abilities of migration and inva-sion were significantly increased in Prdx4-overexpressing HeLa cells compared with non-transfected and mock plasmid trans-fected control groups ( P<0.01) .When Prdx4 was knocked down by shRNA, the migration and invasion of the HeLa cells were remarkably repressed compared with blank control group and negative control group ( P<0.01 ) .CONCLUSION:The up-regulation of Prdx4 expression facilitates the migration and invasion of HeLa cells, and the down-regulation of Prdx4 expression inhibits the migration and invasion of HeLa cells, indicating that Prdx4 may be a potential molecular target for cervical cancer therapy.

Objective To investigate the efficacy of gelatin sponge particles(GSP)or polyvinyl alcohol particles (PVA) for hemoptysis secondary to bronchiectasis or pulmonary tuberculosis. Methods The clinical data on 271 patients with bronchiectasis- or tuberculosis-induced hemoptysis were retrospectively analyzed. The efficacy and rates of recurrence and complications were analyzed. Results A total 271 patients were included in this study, 176 of whom suffered from bronchiectasis and the rest 95 had tuberculosis. One-week cure rate was signifi-cantly higher in bronchiectasis group than in tuberculosis group(73.3%vs. 46.3%,P<0.05),and one-year recur-rence rate was significantly lower in bronchiectasis group(17.6%vs. 26.3%,P<0.05). One-year recurrence rate was slightly higher in patients receiving GSP than in those undergoing PVA(bronchiectasis group:22.2%vs. 10.3%, P<0.05;tuberculosis group:28.8%vs. 22.2%,P>0.05). No severe complications occurred. Conclusions In-terventional artery embolization therapy for hemoptysis secondary to bronchiectasis is better than tuberculosis-induced hemoptysis,and PVA is more effective than GSP. Recurrence of massive hemoptysis mostly occurrs within one month ,and most of the patients are complicated with blood supply and have a history of hemoptysis.

Objective:To investigate the effects of two SNP sites of delta-like ligand protein-1 (DLL1) gene rs2738822 (C>T) and rs9459988 (T>G) and gene expression on bone marrow suppression after neoadjuvant chemotherapy for breast cancer.Methods:Breast cancer patients who received neoadjuvant chemotherapy were selected as study subjects, including 90 patients with severe bone marrow suppression and 72 patients with mild bone marrow suppression. Patient’s demographic characteristics and laboratory test indicators were collected. Two SNP sites of DLL1, rs2738822 and rs9459988, were genotyped by capillary electrophoresis and section analysis (SNaPshot) . The relative mRNA expression of DLL1 gene was detected by quantitative reverse polymerase chain reaction (QRT-PCR) method.Results:For The rs2738822 of DLL1 gene, the genotype distribution difference between severe and mild bone marrow suppression groups was statistically significant ( χ2=8.622, P=0.013) . Compared with CC genotype, CT and TT genotype carriers had a higher risk of severe bone marrow suppression, with an OR value of 2.746 (1.335-6.882) and 3.054 (1.282-8.143) , respectively. The dominant model results showed that TT OR CT carriers had a significantly higher risk of severe bone marrow suppression than THOSE with CC genotype [ OR=2.976 (1.231-4.963) ]. For rs9459988, there was no significant difference in genotype distribution between severe bone marrow suppression group and mild bone marrow suppression group ( χ2=2.149, P=0.342) . Results of the dominant model showed that TG or GG carriers had a significantly higher risk of severe bone marrow suppression than TT carriers, with an OR value of 2.046 (1.053-5.611) . The relative mRNA expression level of DLL1 gene was 1.15±0.23 in patients with severe bone marrow suppression, which was significantly lower than that in patients with mild bone marrow suppression (2.64±0.51) ( t=6.381, P<0.001) . For rs2738822, with the increase of T allele, the relative mRNA expression level of DLL1 gene decreased gradually ( P<0.05) . For rs9459988, the relative mRNA expression level of DLL1 gene in patients with mutant allele G was also significantly lower than that in wild-type CC carriers ( P<0.05) . Conclusion:Mutations of DLL1 genes rs2738822 and rs9459988 are related to the occurrence of severe bone marrow suppression after neoadjuvant chemotherapy for breast cancer, and can be used as a genetic marker to predict the degree of bone marrow suppression after neoadjuvant chemotherapy for breast cancer patients.

To identify the structure of three related substances in potassium sodium dehydroandrographolide succinate (PSDS), an HPLC preparation method was used to separate the impurities. These main impurities were identified using LC-ESI/TOFMS, LC-ESI/MSn, NMR, UV and IR. One of the main impurities was a hydrolyzed and oxidized product of PSDS, which has not been reported previouely. The other two impurities were hydrolyzed products of PSDS after losing different succinic acids. The results indicate that PSDS can be easily hydrolyzed and oxidized. It should be stored at cool and dry places.
