ABSTRACT
To investigate the clinical significance of serum soluble programmed cell death ligand-1 (PD-L1) in adult patients with community-acquired pneumonia (CAP). A total of 44 CAP patients, 54 severe CAP patients and 30 healthy volunteers were recruited in this study. Serum soluble PD-L1 were detected. Univariate and multivariate regression analyses were used to assess the influence of multiple clinical variables on prognosis. Serum soluble PD-L1 level in severe CAP group was 98.20(57.94, 128.90) ng/L, which was significantly higher than that in the CAP group [59.32(33.55, 92.58) ng/L] and healthy controls [20.44(12.15, 36.20) ng/L] (all P<0.001). PD-L1 level was positively correlated with CRUB-65( r=0.481, P<0.001) and the pneumonia severity index (PSI) score ( r=0.442, P<0.001). Univariate regression analysis showed that CURB-65 ( HR=2.544, 95% CI 1.324-4.889, P=0.005), PSI score ( HR=1.036, 95% CI 1.012-1.061, P=0.004), soluble PD-L1( HR=1.013, 95% CI 1.001-1.026, P=0.041) were risk factors of mortality during hospitalization. Multivariate regression analysis suggested that PSI score ( HR=1.042, 95% CI 1.012-1.073, P=0.005), soluble PD-L1 ( HR=1.011, 95% CI 1.002-1.071, P=0.020) were independent predictors for mortality risk in CAP patients. CAP patients with soluble PD-L1≥98.20 ng/L had a significantly lower survival rate than those with soluble PD-L1<98.20 ng/L ( P=0.033). In conclusion, this study indicates that serum soluble PD-L1 level in CAP patients is correlated with the survival prognosis.
ABSTRACT
Objective To investigate the expressions of homeobox gene 10 (HOXD10) and analyze its clinical significance. Methods Expressions of HOXD10 protein was detected by immunohistochemistry SP method in 53 cases of colorectal carcinoma tissues and corresponding normal tissues which was fixed by 4% formalin and embedded by paraffin.It was analyzed that the relationship between the expression of HOXD10 protein and clinico-pathological features. Results The positive staining rate of HOXD10 protein in normal colorectal mucosal tissue (5.7%)was significantly lower than that incolorectal carcinoma tissue(64.2%),the difference was statistically sig-nificant(P<0.05). In colorectal cancer tissue,the positive rate of HOXD10 protein in high differentiation(53.8%), T1+T2(38.5%),Ⅰ+Ⅱ(54.3%)and no lymph node metastasis(55.3%)was lower than that in low differentiation (73.0%),T3+T4(72.5%),Ⅲ+Ⅳ(83.3%)and lymph node metastasis,the difference was statistically significant (P < 0.05). However,it was not statistically significant between the positive rate of HOXD10 protein and the gender,age,primary site and tumor size in colorectal cancer patients(P>0.05). Conclusion The expression of HOXD10 protein is closely related to the invasion and metastasis of colorectal cancer.

ABSTRACT
Objective To study the expression and function of miR-145 in papillary thyroid carcinoma (PTC).Methods PTC tissues and adjacent tissues were collected from 43 cases.Expression of miR-145 in PTC tissues and adjacent tissues was detected with RT-PCR.miR-145 analogue was used to transfect TPC-1cell to upregulate miR-145 expression.Brdu-ELISA method was used to detect the proliferation of TPC-1 cell.Flow cytometry instrument was used to detect the apoptosis and cell cycle of TPC-1 cell.Results RT-PCR test showed that relative expression of miR-145 in thyroid carcinoma tissue was 0.369±0.082,significantly lower than 1.029-±0.365 in tissue adjacent,and the difference was statistically significant (t=3.129,P=0.000).The expression of miR-145 in patients whose biggest tumor size ≥ 1 cm was lower than patients whose biggest tumor size ＜1 cm.Compared with patients with single tumor,the expression of miR-145 in patients with multiple tumor was lower,and the dif ferences were statistically significant (P＜0.05).miR-145 expression was enhanced by miR-145 analogue.Compared with negative control,the proliferative ability of thyroid cancer cell TPC-1 was suppressed significantly,and the difference was statistically significant (P＜0.05).In addition,up-regulation of miR-145 expression could block thyroid cancer TPC-1 in G2/M phase.The apoptosis rate of thyroid cancer cell TPC-1 increased significantly (P＜0.05).Conclusions miR-145 expression is decreased significantly in PTC tissue,and is associated with clinical pathological features.Up-regulation of miR-145 expression can inhibit thyroid cancer cell proliferation,block the cell cycle,and promote apoptosis,miR-145 may play an important role in occurrence and development of thyroid cancer.
ABSTRACT
Objective To investigate the application value of anatomic segmental hepatectomy in treatment of left hepatolithus.Methods The 80 patients with left hepatolithuswere divided into the control group (n =40)and the observation group (n =40)in accordance with dif-ferent surgical methods,and they were given traditional surgery and precise pedicle anatomic segmental hepatectomy respectively.Operation index levels,postoperative complications and stress reaction levels before and after surgery of the two groups were compared.Results The blood loss,operative time,the time of drainage tube remove,time of analgesic drug use,and postoperative hospital stay of the observation group were significantly less than the control group,and the difference was statistically significant (P 0.05).During the surgery,epinephrine,cortisol,IL-6 and CRP levels of patients decreased after a slight increase, while NK cell levels of patients decreased firstly and then increased.There were statistically significant differences in trems of the above inde-xes immediately after surgery to 24 hours after surgery (P <0.05),and the rangeability of the observation group was less than the control group (P <0.05).Until 48 hours after surgery the above indexes recovered to the preoperative level.Followed up for 3 to 24 months,the calculi recurrence rate and abdominal ache recurrence rate of the observation group were lower than the control group,and the difference was statistically significant(P <0.05).Conclusion Precise pedicle anatomic segmental hepatectomy applied in the treatment of left hepatolithus showed makedly curative effect,and it has little effect on the stress response of patients.
