Objective To find out evidences for the identification of Ajuga decumbens Thunb.(Jinchuangxiaocao) and Pogostemon cablin (Blanco.) Benth.(Guanghuoxiang) . Methods Fresh stems and leaves of the two species were collected and used as the samples. We used stereoscopy to observe and compare the macroscopic appearance of the original plants, and used light microscope to observe the stem cross-section, petiole cross-section, leaf epiderm and powder of the two species for microscopic identification. Results The results of macroscopic character identification showed that the petiole of Jinchuangxiaocao had narrow wing, while that of Guanghuoxiang had no narrow wing; the angles between leaf main vein and lateral vein of Jinchuangxiaocao were less than 45°, while the angles of Guanghuoxiang were more than 45°. In respect of microscopic identification, Jinchuangxiaocao had the glandular scales with multicellular head, and Guanghuoxiang had the glandular scales with one-celled head; the intercellular space and crystals were found in the cortex of Guanghuoxiang stems and mesophyll, while Jinchuangxiaocao has no such structures. Jinchuangxiaocao had diacytic and anomocytic stomata, and Guanghuoxiang only had diacytic stomata. Conclusion The appearance and microscopic differences can be used for the identification of Jinchuangxiaocao from Guanghuoxiang.

Objective To investigate whether the single nucleotide polymorphisms (SNP) in DNA repair gene XRCC1(X-ray repair cross-complementing 1) were associated with the survival of cisplatin based combination concurrent chemoradiotherapy in esophagus cancer. Methods Overall 286 esophagus cancer patients receiving cisplatinum based chemotherapy were investigated. 5' nuclease allelic discrimination assay (TaqMan) and real-time PCR were taken to assess XRCC1 genotypes. Efficacies and adverse-effects were analyzed individually according to their genotype. Results Short-time effects showed the RR rate in patients with Arg/Arg and Arg/GIn genotypes(A group) was 93.56 %, significantly higher than 69.81% (P<0.05) in patients with GIn/GIn genotype (B group). The 1-year and 3-year survival rates were 82.8 %, 41.2 % in A group, significantly (P<0.05) different from 58.5 %, 26.4 % in B group, respectively. No statistically differences were found on adverse effects. Conclusion Significant relationships are found between single nucleotide polymorphisms in XRCC1 and outcome in esophagus cancer receiving cisplatin based concurrent chemoradiotherapy.

Background Spectral-domain optical coherence tomography (SD-OCT) can quantitatively analyze some ocular parameters in vivo.Although human ocular parameters have been obtained by SD-OCT,few studies were performed in animal experiment.Objective This study was to investigate the anterior and posterior segment parameters of C57BL/6 mice and pigmented rabbits using SD-OCT in vivo.Methods Some anterior and posterior segment ocular parameters,including the central corneal thickness (CCT),anterior chamber depth (ACD),white-to-white (WTW),optic nerve head (ONH) depth/width and retinal thickness,were measured in 8 eyes of 4 health SPF C57BL/6 mice and 12 eyes of 6 health SPF pigmented rabbits using SD-OCT.Results For C57BL/6 mice,Cornea,iris,lens in pupil area were clearly exhibited by SD-OCT.Mean CCT,ACD and WTW were (96±9)μm,(460±8) μm and (2.86 ± 0.41) mm pre-mydriasis,respectively,the corresponding values of post-mydriasis were (96±8) μm,(356±20)μm and (2.87±0.62)mm.There were no statistical differences of CCT and WTW between pre-and post-mydriasis (t =0.478,P =0.647 ; t =-0.737,P =0.485).ACD of post-mydriasis was significantly shallower than that of baseline (t =-13.022,P＜0.001).For the pigmented rabbits,the thickness of corneal thinnest point,retinal thickness,ONH depth and width were (370 ± 10) μm,(175 ± 4) μm,(1.35 ± 0.51) mm and (4.52±0.82) mm,respectively.Conclusions As a non-contact and non-invasive technology,SD-OCT can provide not only high resolution cross-sectional ocular images,but also high precise quantitative parameters for both C57BL/6 mouse and pigmented rabbit in vivo.

Objective To observe the incidence and transformation of pyuria and bacteriuria in different time point after TURP and supply the evidence for antibiotic application.Methods From March,2011 to May,2012,84 patients with BPH admitted in our hospital.Their ages ranged from 61 to 87 years old,mean (71.9±7.6) years.The volume of prostate in those patients ranged from 27.8 to 118 ml,mean (70.8±24.1) ml.The procedure of TURP was undergone in all of them.In one week after the operation,two urine specimens from each patient,one for urine routine examination and one for urine culture,were collected 24 h after the catheter have been withdrawn.The catheter was also cultured.During the following-up,urine routine examination and urine culture were regularly performed in 1,2,3 months after surgery.If the patient had both pyuria and bacteriuria,he should be excluded the study.Results The pyuria rate on one week,one month,two months and three months were 54.8％ (46/84),100.0％ (82/82),65.8％ (48/ 73),34.2％ (25/73),respectively.There is a significance difference among those groups (P＜0.05).It seemed that the pyuria would appear in all patients.However,the incidence would gradually decrease.It seemed that the pyuria has the tendency of self-recovery.A significant difference of prostatic resection volume after 3 months could be observed in the pyuria group (31.4±15.2 ml) and non-pyuria group (24.8±11.6 ml) (P＜0.05).The bacteriuria rate on one week,1,2,3 months were 7.1％ (6/84),11.0％ (9/82),6.8％ (5/73)and 0,respectively.There is no significance difference among the groups (P＞0.05).Conclusions Pyuria will appear after TURP and the incidence reduced gradually following the time.The pyuria alone without the bacteriuria may be explained by inflammation,that antibiotics were unnecessary.The bacteriuria alone without the pyuria may be considered as asymptomatic bacteriuria or bacterial colonization,antibiotics were unnecessary,either.

Objective: To observe the clinical effect of integrated traditional and western medicine in treating chronic idiopathic thrombocytopenic purpura (CITP) elderly patients. Methods: Sixty patients were divided randomly into the treatment group (n=30) and the control group (n=30), the former was treated with danazol combining with prednisone and Chinese drugs, while the latter was treated with VCR. Results: The total effective rate of the treatment group was better than that of the control group, the difference between those two groups was significant (P

Objective To examine the expressions of serum growth hormone (ghrelin), leptin (LP), in sulin-like growth factor-1 (IGF-1) and insulin-like growth factor binding protein-3 (IGFBP3) in children with id-iopathic short stature (ISS), and their significance. Methods A total of 40 patients with ISS were selected from May. 2012 to Oct. 2014 in Fuyang Maternal and Child Health Hospital, while a total of 40 children in good health were selected as the control group. Serum ghrelin and LP levels were measured by ELISA. Serum IGF-1 and IGF-BP3 levels were detected by chemiluminescence immune assay. Results were analyzed statistically. Results The height, weight, BMI, GH, serum LP, IGF-1, and IGFBP3 levels in the observation group were significantly lower than those in the control group, while serum ghrelin expression level was significantly higher than that in the control group(P<0.05). The correlation analysis showed that ghrelin and LP were negatively correlated(r=-0.611, P<0.01), ghrelin and IGF-1 levels were negatively correlated(r=-0.520, P<0.05), Ghrelin and IGFBP3 were pos-itively correlated (r=0.586, P<0.01), IGF-1 and IGFBP3 was negatively correlated (r=-0.576, P<0.01), and LP and IGFBP3 were negatively correlated (r=-0.609, P<0.01). Conclusions It shows that ghrelin, LP, IGF-1, and IGFBP3 levels in children with ISS are related to growth hormone secretion status. The interactions between ghre-lin and insulin-like growth factor axis regulate growth and development of children.
