OBJECTIVETo observe the therapeutic effect of the low molecular weight heparin calcium (LMWHC) combined with Yinxin Damo Injection (YDI) on the prevention of deep venous thrombosis (DVT) after the operation of intertrochanteric fracture.

METHODSSixty-two patients with intertrochanteric fracture were randomly assigned to the control group and the combined group, 31 in each group. Patients in the control group were subcutaneously injected with 6 000 IU LMWHC, twice daily. On this basis of the aforesaid treatment, patients in the combined group were intravenously dripped with YDI at the daily dose of 20 mL, once daily. The treatment lasted for 10 days in both groups. The DVT incidence rate, postoperative drainage amount of blood, activated partial thromboplastin time (APTT), plasma prothrombin time (PT), platelet count, and the maximal swelling rate of lower limbs after surgery were compared between the two groups after operation.

RESULTSIn the control group DVT occurred in 5 cases (16. 1%) while it occurred in 2 cases (6.5%) in the combined group, showing significant differences (P < 0.05). Both APTT and PT were shortened in the two groups on the 2nd day after medication (P < 0.01). Compared with the control group, it was more obvious in the combined group, showing statistical significance (P < 0.05). Both APTT and PT were shortened in the control group on the 10th day after medication when compared with before treatment (P < 0.01). But they were postponed in the combined group when compared with before medication, showing statistical difference when compared with the control group (P < 0.05). The platelet count increased in the combined group on the 10th day after medication. Besides, it was higher than that in the control group, showing statistical difference (P < 0.05). The platelet counts were in the normal range.

CONCLUSIONSLMWSC combined with YDI could not only reduce the incidence of DVT after the operation of intertrochanteric fracture, but also change the state of higher blood coagulation. It showed significant effect on preventing DVT after the operation of intertrochanteric fractures.

There is controversy regarding the roles of Ureaplasma urealyticum (U. urealyticum) colonization in the development of bronchopulmonary dysplasia (BPD). This study explored the association between U. urealyticum and bronchopulmonary dysplasia at 36 weeks post-menstrual age (BPD36). Studies published before December 31, 2013 were searched from Medline, Embase, Ovid, Web of Science, and Cochrane databases, with the terms "Ureaplasma urealyticum", "chronic lung disease", or "BPD36" used, and English language as a limit. The association between U. urealyticum colonization and BPD36 was analyzed with RevMan 4.2.10 software, using the odds ratio (OR) and relative risk (RR) for dichotomous variables. Out of the enrolled 81 studies, 11 investigated the BPD36 in total 1193 infants. Pooled studies showed no association between U. urealyticum colonization and subsequent development of BPD36, with the OR and RR being 1.03 (95% CI=0.78-1.37; P=0.84) and 1.01 (95% CI= 0.88-1.16, P=0.84), respectively. These findings indicated no association between U. urealyticum colonization and the development of BPD36.

OBJECTIVETo investigate the application of free anterolateral thigh myocutaneous flap in the reconstruction of tongue and mouth floor defect after radical resection of tongue carcinoma.

METHODSFrom June 2006 to April 2009, 14 cases with tongue carcinoma underwent radical resection, leaving tongue and mouth floor defects which were reconstructed by anterolateral thigh myocutaneous flaps at the same stage. These 14 cases included tongue carcinoma at lingual margin (n=9), at ventral tongue (n=3) and at mouth floor (n=2). The flap size ranged from 7 cm x 9 cm to 5 cm x 7 cm.

RESULTSAll the 14 flaps survived completely with primary healing. There was no functional morbidity in the lower extremities. The patients were followed up for 12-26 months with satisfied esthetic and functional results in reconstructed tongue. Only one case (T4 N1 M0) died of metastasis carcinoma 14 months after operation. No local recurrence happened.

CONCLUSIONSThe anterolateral thigh myocutaneous flap has abundant tissue volume to reconstruct the tongue and mouth floor defect, while leaving less morbidity at donor site. Both satisfied esthetic and functional results can be achieved.

OBJECTIVETo evaluate the roles of total prostate specific antigen (tPSA), PSA density (PSAD) and biopsy Gleason score in predicting the pathologic stage of prostate cancer.

METHODSWe retrospectively analyzed the clinical data of 124 cases of pathologically confirmed prostate adenocarcinoma, and divided them into Groups A (n=48) and B (n=76) based on the results of bone scanning, CT, MRI, tPSA, PSAD and postoperative biopsy Gleason score, the former with extraprostatic infiltration or distant metastasis, while the latter without. We compared the above parameters between the two groups, screened the main factors that influenced the pathologic staging of prostate cancer by multivariate logistic regression analysis, and appraised the value of each of the parameters in predicting the pathologic stage of prostate cancer with a relative operating characteristic (ROC) curve.

RESULTSThe tPSA level and biopsy Gleason score were significantly higher in Group A than in B (P < 0.05). Multivariate logistic regression analysis showed that only tPSA could predict the pathologic stage of localized prostate cancer. The ROC curve exhibited that the combined use of tPSA and Gleason score had a better predicting value than other parameters (Gleason score + tPSA > tPSA > PSAD + tPSA + Gleason score).

CONCLUSIONTotal PSA remains a valuable predictor of the pathologic stage of prostate cancer, and its combination with Gleason score can further improve the predictive accuracy and contribute much to the treatment and prognosis of the disease.

BACKGROUNDThe Taq/B, Msp/ and I405V polymorphisms of cholesteryl ester transfer protein (CETP), an important regulatory factor of lipid metabolism, have been attracted much more attention by the researchers. In this study, we investigated the associations between these 3 polymorphisms of CETP gene and variations in plasma lipid and lipoprotein levels in patients with coronary heart disease (CHD).

METHODSGenomic DNA was extracted from leukocytes of 203 CHD patients and 100 control subjects using the salting out method. Genotyping of the CETP gene was performed using polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP) techniques. Statistical analysis was conducted using the SPSS 10.0 software package.

RESULTSThe distribution of allele and genotype frequencies of the Taq/B, MspI, and I405V polymorphisms was similar in the CHD patient group and the control group. The B1B1 genotype of the Taq/B polymorphism was associated with significantly higher TC (P=0.039) and LDL-C (P=0.044) levels than the B2B2 genotype in CHD patients, and with significantly higher LDL-C (P=0.034) levels than the B2B2 genotype in controls. Homozygotes of the I405V polymorphism exhibited significantly higher HDL-C levels than VV homozygotes among control subjects (P=0.023). In male CHD patients with unambiguously assigned haplotypes, B2-M2-V/B2-M2-I patients demonstrated significantly higher HDL-C concentrations than B1-M2-V/B1-M2-I (P=0.023) and B1-M2-V/B1-M2-V patients (P=0.047).

CONCLUSIONSGenetic variations in the CETP gene may account for a significant proportion of the differences in plasma lipid and lipoprotein concentrations among the general population. The B1B1 genotype of the Taq/B polymorphism is probably a genetic risk factor for CHD in the study population.
