Objective To explore the expression of tissue inhibitor of metalloproteinases-2(TIMP-2) in peripheral blood lymphocytes in patients with chronic obstructive pulmonary diseases(COPD) and the association of smoking and TIMP-2 mRNA. Methods The expression of TIMP-2 mRNA in peripheral blood lymphocytes was measured by reverse transcription-polymerase chain reaction(RT-PCR) in 44 patients with COPD and 42 healthy smokers.The correlation analysis was then conducted between TIMP-2 mRNA expression and smoking index. Results The expression of TIMP-2 mRNA was 0.753?0.154 and 1.170?0.196,respectively,in patients with COPD and healthy smokers(P

Objective To report our clinical outcomes of treating tibial defects combined with soft tissue defects using Ilizarov technique.Methods From May 2010 to February 2015,52 patients with combined bone and soft tissue defects of the tibia were treated at our department.They were 41 males and 11 females,aged from 19 to 65 years (average,37.7 years).By Gustilo classification,49 cases were type ⅢB and 3 type ⅢC.The areas of soft tissue defect ranged from 7 cm ×3 cm to 28 cm × 15 cm,and the tibial defects ranged from 5 cm to 15 cm in length (average,12.6 cm).The schemes of Ilizarov technique depended on the location and size of the tibial defects.Open wound dressing combined with bone transport was adopted in 21 cases,limb shortening followed by bone lengthening with compression at the fracture ends in 12 cases,and tissue flap transplantation combined with bone transport or lengthening in 19 cases.Results The follow-up time of the 52 patients ranged from 13 to 61 months (average,27.1 months).The distance of bone transport or lengthening ranged from 5.0 cm to 13.6 cm (average,10.8 cm);the bone transport speed averaged 0.81 mm/day.The tibiae united in all the 52 patients;the time for external fixation ranged from 13 to 21 months (average,15.3 months);the external fixation index was 2.3 months/cm.According to the Paley functional criteria,23 cases were excellent,19 good,9 fair,and one poor,yielding an excellent to good rate of 80.7%.Conclusion According to the location and size of the bone and soft tissue defects of the tibia,the 3 schemes of Ilizarov technique can be rationally chosen to obtain fine clinical outcomes.

OBJECTIVETo investigate the indication of Fuzheng Huayu Capsule (FHC) against hepatic fibrosis and its non-invasive efficacy evaluation parameters.
METHODSData involving hepatic fibrotic patients received twice liver biopsy before and after FHC treatment were received from multi-center, randomized, double-blind, controlled clinical trials and analyzed. The changes of indexes related to inflammation of hepatic tissue and liver function, serological and virologic parameters of fibrosis, blood routine test, hepatic ultrasonic test as well as clinical symptoms and signs of patients were compared between patients alleviated (assigned to the effective group) and un-alleviated (assigned to the ineffective group) by the treatment.
RESULTS(1) The degree of liver fibrosis, ALT activity and the scores of symptoms of hypochondriac pain and dry mouth before treatment were remarkably higher in the effective group than those in the ineffective group. (2) Level of ALT activity decreased in both groups after treatment. In the effective group, the grading scores of hepatic inflammatory significantly decreased after treatment (P < 0.01), levels of AST and GGT decreased after 3 months' treatment, and levels of GGT and PT significantly decreased after treated for 6 months, as compared to those in the ineffective group, showing significant difference. (3) Levels of serum hyaluronic acid (HA) and collagen type III (P-III-P) remarkably decreased after 12 weeks' treatment in the effective group. (4) Symptoms and signs were improved at various degrees in the two groups, but the improvement in dim and blackish complexion was more significant in the effective group than that in the ineffective group. (5) The changes in virologic parameters of hepatitis B virus, blood routine and hepatic ultrasonic test between the two groups showed no significant difference respectively.
CONCLUSIONS(1) FHC showed better effect against hepatic fibrosis in patients of fibrotic stage around S3, with obvious active hepatic inflammation and symptoms of hypochondriac pain and dry mouth, which could be taken as a referential index in clinical practice for indication decision. (2) The increase of serum albumin, decrease of GGT, AST, PT, HA, and P-III-P as well as the improvement of signs of dim and blackish complexion could be regarded as the referential indexes of effectiveness of FHC against hepatic fibrosis. These parameters are valuable non-invasive indices for diagnosis of hepatic fibrosis and efficacy evaluation of its treatment.

Objective To establish real-time PCR with SYBR Green Ⅰ for quantification the gene of survivin.Methods The components and conditions of PCR system were optimally determined by fluorescence intensity,cycle threshold(Ct),melting curve,coefficiency and slope of the standard curve.The means to eliminate the contaminating fluorescence of primer-dimers and the mode for Ct value determination were also optimized.Using the developed PCR system,we quantificated the survivin gene in 43 patients with gastric carcinoma.Results The optimized condition for PCR amplification of survivin were 2 mmol/L of MgCl_2,2.5 U/100 ?l of Taq DNA polymerase,0.2 ?mol/L of primers,and the optimized annealing temperatures for PCR were 58℃.The influence of primer dimmer can be eliminated by setting the fluorescence collecting temperature below the Tm of the specific amplicon by 2℃.The second derivative maximum mode,instead of fit point mode,was a feasible method to determine the Ct value for quantification.The sensitivity of this method was 10 copies/?l,and a good linearity was found from 10~1 to 10~4 copies/?l(r = 0.999 7).The inter-experimental coefficient of variation was 1.13%-1.91%,whereas the coefficient of variation between runs was 3.31%-4.50%.Using the optimized PCR system,we quantificated the gene of survivin,the result indicated that survivin gene was amplified in 13.9% of gastric carcinomas.Conclusions The optimal real-time PCR with SYBR Green Ⅰ,as a cost-effective and feasible DNA quantitative method,is fit for quantification of the survivin with satisfactory repeatability and high sensitivity.
