Objective To study the intra- tumor basis of pleural indentation (P I) and find the influential factors correlated with PI in peripheral lung cancer . Methods Eighty-six cases of peripheral lung cancer (includin g experimental gr oup of 34 cases with PI and control group of 52 cases without PI) were subjected to identify the constitution in tumoral interstitium. And 7 variables (includin g intra-tumor fibrosis, tumor-chest wall distance, histological type, diameter o f tumor, differentiated degree, lymphatic metastases, sex, etc.) were investigat ed about PI by single factor analysis and multiple factor analysis of Logistic r egression model. Results(1)Collagenous fibers were the mai n fiber in tumoral interstitium, and were higher in experimental group than that in control group ( t=3074, P005). Conclusion Collagen Ⅰfibers are the main type of interstiti al fibers, and myofibroblasts are the main type of interstitial cells in PI asso ciated peripheral lung cancer. Intra-tumor fibrosis, tumor-chest wall distance , and histological types are the main influential factors in PI formation, and int ra-tumor fibrosis is the basic and inside factor. The histological types affect PI formation. Tumor-chest wall distance plays an important outside role in PI f ormation.

Objective To predict the occurrence of hypoparathyroidism following total thyroidectomy. Methods In this study, 124 patients underwent total thyroidectomy, 46 for thyroid cancer and 78 for multinodular goiter, additional neck dissection was performed on cancer patients. Serum calcium and parathyroid hormone (PTH) levels were examined preoperatively and at 1 h, 1 d and 2 d postoperatively. The occurrence of postoperative hypoparathyroidism was observed. Receiver operating characteristic curve analysis was employed to identify the best indicator to early predict the occurrence of clinical hypocalcemic symptoms. Results Fifty-eight (46.8%) patients suffered from postoperative transient hypoparathyroidism, with 22 ( 47. 8% ) cases in thyroid cancer group and 36 ( 46. 2% ) in multinodular goiter group ( λ2 = 0. 033, P = 0. 857). One (0.8%) patient in cancer group had permanent hypoparathyroidism. 90 patients (72.6%) had postoperative hypocalcaemia, 58 (46. 8% ) had subnormal serum PTH levels, 40 (32. 3% ) had hypocalcaemia symptoms. Postoperative serum calcium (F=21. 358,P =0. 000) and PTH ( F = 18.253, P =0.000) levels decreased more in cancer group than in goiter group.Receiver operating characteristic curve analysis demonstrated that the percentage of serum PTH level decline at 1 h postoperatively was most predictive and 76. 6% decline was the best cut-off value for the occurrence of clinical hypocalcaemia symptoms ( area under the curve being 0.933 ) with a sensitivity of 89. 7% and a specificity of 87.9%. Conclusions Neck dissection added to total thyroidectomy can decrease the postoperative serum calcium and PTH levels more seriously, but may not increase the incidence of postoperative transient hyperparathyroidism. The percentage of serum PTH level decline at 1 h postoperatively predicts the occurrence of clinical hypocalcaemia symptoms.

Objective To detect the relationship between XPD Lys751Gln polymorphism and the risk of adult acute leukemia (AL). Methods 100 adult AL patients and 100 controls were chose as case and Lys751Gln were genotyped by polymerase chain reaction-restriction fragment length polymorphism (PCRRFLP) analysis in peripheral blood. Results The genotype frequency of Lys/Lys, Lys/Gln, Gln/Gln were 83 %, 16 %, 1% in case group and 90 %, 10 %, 0 in control group, respectively. The difference the two groups was no signficant difference (x2=1.44, P =0.49). No significantly increased risk for adult AL was observed for those carrying variant genotype with OR analysis (x2 = 2.10, P =0.15, OR =1.84; 95 % CI 0.80-4.25). Individuals with the variant genotype of XPD Lys751Gln might enhance the risk of adult AL (OR =2.77, 95 % CI 0.99-7.73). Conclusion XPD Lys751Gln polymorphism is found to have relationship with adult acute lymphocytic leukemia.

30 kg/m2 served as obesity group.Using Gross formula,the true total blood loss was calculated depending on the height,body mass and pre-and post-operative Hct,and hidden blood loss was gotten by subtracting the visible blood loss from total loss.③The correlation between visible and hidden blood loss was observed.RESULTS:All 41 patients undergoing THA and 37 TKA were involved in the result analysis.①Following THA,the mean total loss was 1 520 mL and the hidden blood loss 482 mL(32%).Following TKA,the mean total loss was 1 508 mL and the hidden blood loss was 776 mL(52%).The hidden blood loss between THA and TKA was significantly different(P 0.05).CONCLUSION:①The hidden blood loss in TKA is far higher than THA.It is very important to supplement the blood volume during TKA for the insufficiency to regain general circulation although using blood re-infusion.②It may improve clinical evaluation capabilities to estimate hidden blood loss and thus result in better patient care after joint arthroplasty.

Background The characteristics of anisometropic amblyopia in ocular morphology are becoming a hot topic in amblyopia field.And the interocular difference in corneal parameters of anisometropic amblyopia is to be understood here.Corneal topography is a non-invasive method for in vivo corneal examination and applied in our study.Objective This study was to investigate the interocular difference of corneal topography in anisometropic amblyopic patients Methods This was a serial cases observation.Thirty anisometropic amblyopes were selected in Center for Optometry and Visual Science,People's Hospital of Guangxi Zhuang Autonomous Region.The patients were divided into amblyopic eye group and fellow eye group based on the best corrected distance visual acuity.Corneal topography was examined with Orbscan Ⅱ z,and corneal morphological parameters such as Diff values of the anterior and posterior corneal surface,Sim K 's astigmatism,Kmax,angle kappa and central corneal thickness (CCT) were measured.The interocular differences in these parameters were evaluated by paired t test,and the correlations in these parameters between the amblyopic eyes and the fellow eyes were analyzed by Pearson linear correlation and simple regression analysis.Results The Diff values of the anterior corneal surface were (0.011±0.006)mm and (0.011±0.017)mm,and those in the posterior corneal surface were (0.031 ±0.012)mm and (0.026 ±0.008)mm in the amblyopic eye group and the fellow eye group,respectively.In addition,Sim K's astigmatism were (1.8± 1.1)D and (1.1 ±0.6) D,JCC were (77±80) °and (100±80) °,J0 values were (-0.17±0.72) D and (0.02±0.41) D,J45 values were (-0.16±0.79) D and (0.13 ±0.48) D,CCT values were (551 ±37) μm and (551 ±31) μm,angle kappa values were (6.4± 1.4) ° and (4.9 ± 1.2) ° in the amblyopic eye group and the fellow eye group,respectively.Significant differences were found in the Diff values of the anterior and posterior corneal surface,Sim K's astigmatism and angle kappa between the two groups (t=-3.041,P=0.005 ;t=-4.317,P=0.000 ;t=-4.571,P=0.000).Pearson's linear correlation test demonstrated significant interocular positive correlations in parameters such as the anterior corneal surface Diff values (r =0.444),J0 (r =0.383),posterior Diff values (r =0.600),and Sim K 's astigmatism (r =0.479),and CCT (r =0.948,P＜0.05).The linear regression equation between the two groups was Y =-0.005 +1.392X (R2 =0.197,F=6.858,P=0.014) in the Diff values in the anterior corneal surface,Y =-0.013+0.421X (R2=0.360,F=15.761,P=0.000) in the Diff values in the posterior corneal surface,Y =0.616+0.27X (R2=0.230,F=8.348,P=0.007) in the Sim K's astigmatism,Y=0.060+0.219X (R2 =0.147,F=4.814,P=0.037) in theJo and Y=i08.289+0.804X (R2 =0.899,F=250.293,P=0.000) in CCT.Conclusions Corneal morphological interocular differences exist significantly in anisometropic amblyopic patients.

The effects of continuous subcutaneous insulin injection (CSII, n=306) and multiple subcutaneous insulin injection (MSII, n=310)on hyperglycemia in patients with diabetes mellitus were compared. The results suggest that the effect of CSII is more prompt and efficient with lower incidence of hypoglycemia as compared with MSII.

Objective·To explore the biologic effect and mechanism of adenanthin (Aden) on multiple myeloma (MM) cells. Methods·MM cells, H929 and U266 were treated with various dose of Aden for different time, and the density and viability of MM cells were detected by trypan blue exclusion assay. After H929 and U266 cells were treated with various dose of Aden for 24 hours, cell growth inhibition was examined by CCK8 assay, and cell apoptosis was examined by AnnexinV-APC/PI staining assay. Apoptosis related proteins, NF-κB signaling pathway associated proteins and the NF-κB regulated proteins were detected by Western blotting. The effect of Aden on the thermal stability of IKKβ protein was determined by CETSA assay. Results·Trypan blue exclusion results showed that Aden inhibited cell growth and reduced cell viability in concentration and time dependent manners. U266 was more sensitive than H929 when exposed to the same concentration of Aden. The CCK8 results showed that Aden inhibited the growth of H929 and U266 cells in a concentration dependent manner. Flow cytometry results suggested that Aden induced a low apoptosis rate of MM cells. Moreover, cleavage of caspase3 and PARP were detected in U266 cells but not in H929 cells. CETSA assay indicated that Aden decreased the thermal stability of IKKβ. Expression of p-p65 and p-IκBα proteins decreased in MM cells treated with Aden. Conclusion·Aden significantly inhibits MM cell proliferation by inhibiting NF-κB activation through interacting with IKKβ. Aden has little effect on apoptosis of MM cells.
