Objective To investigate the operational timing and manner for the digestive tract reconstruction after Hartmann procedure and the prevention for the postoperative complications in the patients with left colorectal cancer.Methods The data of twenty-four cases with digestive tract reconstruction were analysed retrospectively containing the cause of Hartmann procedure for left colorectal cancer,preoperative evaluation of the digestive tract reconstruction,operation timing,operation manner,postoperative complications and length of hospital stay and so on.Results Three of 24 patients gave up the digestive tract reconstruction due to the results of their distant metastasis detection in the preoperative evaluation.As a commonly manner of digestive tract reconstruction,rectum-sigmoid colon or sigmoid-descending colon end-end anastomosis was used for 17 patients.Meanwhile,ascending colon-sigmoid colon end-side anastomosis was used for 4 patients.The incidence of postoperative complications was 14.29 ％ (3/21),and the mean time of postoperative hospital stay was 10.5 days.Conclusions In patients undergoing Hartmann procedure for left colorectal cancer,adequate assessment of the tumor recurrence and metastasis is necessary.In addition,the optimal timing of surgery should be selected after completion of chemotherapy,and operational manner should be determined by the situation of intraoperative exploration.

BACKGROUND:In total hip arthroplasty, the accurate placement of the acetabulum is needed to guarantee the survival rate of the prosthesis and improve the prognosis. In order to ensure the accurate placement of the acetabulum, the accurate measurement of the abduction angle and the anteversion angle of the acetabulum is needed. OBJECTIVE:To investigate the application value of C-arm X-ray displacement measurement of acetabular anteversion angle and abduction angle in total hip arthroplasty. METHODS:Total y 63 cases undergoing total hip arthroplasty were divided into two groups according to their wil . Patients in the control group (n=30) were implanted with traditional acetabular prosthesis locator. Patients in the observation group (n=33) were implanted with acetabular prosthesis after C-arm X-ray displacement measurement. Acetabular anteversion angle, abduction angle and pelvic inclination were measured before, during and after arthroplasty. Acetabular anteversion angle and abduction angle were measured in both groups after arthroplasty. Pain score and hip function Harris score were recorded in both groups at different time points. RESULTS AND CONCLUSION:(1) No significant difference in acetabular anteversion angle, abduction angle and pelvic inclination was detected before, during and after arthroplasty (al P>0.05). (2) No significant difference in abduction angle was determined between the two groups after arthroplasty (P>0.05), but acetabular anteversion angle was significantly smal er in the observation group than in the control group (P<0.05). (3) At 7 days after arthroplasty, Visual Analog Scale scores were less in the observation group than in the control group (P<0.05). (4) Compared with that before arthroplasty, Harris score was significantly higher after arthroplasty in both groups (P<0.05). Harris score was higher in the observation group than in the control group at 3 and 12 months after arthroplasty (P<0.05). (5) Results indicated that during total hip arthroplasty, C-arm X-ray machine can measure acetabular anteversion angle and abduction angle, and effectively correct pelvic inclination, internal and external rotation, abduction and adduction, improve the accuracy of acetabular cup placement and the quality of replacement surgery, and improve the prognosis of the patients.

Objective To study the levels of soluble thrombomodulin (sTM)in patients with acute coronary syndrome (ACS) and evaluate its clinical significance. Method Measured the sTM levels with enzyme linked immunosorbent assay, and described the characteristics of coronary arteriography, risk factors of coronary heart disease, and adverse events in a case-control study of 48 ACS patients (ACS group)and 10 normal people (control group). Results The level of sTM in ACS group was (3.67±1.71) μg/L, and (2.34±0.43)μg/L in control group (P<0.05). The level of sTM in the patients of risk factors or impaired vessels number more than 2 increased significantly than those in the patients of risk factors or impaired vessols number inferior or equal to 2, (4.93±2.76) μg/Lvs (3.13±0.81) μg/L, P<0.05, (4.60± 2.83) μg/L vs (2.91±0.23) μg/L, P < 0.05 respectively. The incidence of cardiac events in the patients of sTM more than 3.2 μg/L (70.0%)was higher significantly than that in the patients of sTM inferior or equal to 3.2 μg/L(35.7%), P< 0.05. Conclusions The levels of sTM are valuable markers to evaluate the impaired degree and scope of endothelial cells in ACS. They are also associated with the number of risk factors, and useful in predicting the extent and prognosis of the disease.

Objective To investigate the correlation between type H hypertension and the development of coronary atherosclerosis.Methods From January 2015 to December 2016,three hundred and sixty patients with essential hypertension complicated with coronary atherosclerosis were treated in First Hospital of Shijiazhuang were selected,according to the level of serum homocysteine (Hcy),the patients were divided into the observation group (n =197 cases,Hcy ≥ 10 μ mol/L) and the control group (n =163 cases,Hcy＜10 μmol/L),all patients underwent coronary angiography and intravascular ultrasound.Results The cross-sectional area of extravascular elastic membrane (EEMCSA),plaque area (PA) and plaque burden(PB) of the observed group were (15.10±0.91) mm2,(8.80±0.99) mm2 and (62.03±3.20)％,wrere obviously higher than thoseat of the control group((13.72±0.96) mm2、(7.92±0.89) mm2、(56.87 ±3.37) ％),and the difference was statistically significant (t =14.079,、8.864,and 14.983,P＜0.05),and the minimum lumen cross section area (MLA) was (5.40 ±0.64) mm2,were obviously lower than that of the control group ((5.89 ± 0.52) mm2),and the difference was statistically significant (t =-7.937,P＜0.05);The Gensini score of the coronary artery in the observation group was (67.64± 13.19) points,which was significantly higher than that in the control group ((55.34± 12.20) points),and the difference was statistically significant (t =9.190,P＜0.05);the Serum Hcy were positively correlated with PA,PB and Gensini scores in the observation group (r =0.873,0.732and 0.856,P ＜ 0.05),which was negatively correlated with MLA (r =-0.773,P＜0.05).Conclusion There is a certain correlation between the severity of coronary atherosclerosis and the level of serum Hcy in patients with type H hypertension,which is worthy of further study.

Objective To analyze the dosimetric features of chest wall radiotherapy after modified radical mastectomy for left breast cancer using the beam’s eye view (BEV) in intensity-modulated radiation therapy (B-IMRT). Methods A total of 13 patients treated with modified radical mastectomy for left breast cancer in the Liaocheng People’s Hospital from May 2020 to November 2020 were recruited. They were treated with postoperative radiotherapy using the plans of B-IMRT or tangential fields in intensity-modulated radiation therapy (T-IMRT). The mean dose, conformity index and homogeneity index of the target field, and dose volume parameters of left lung and heart were compared between two groups. Results Compared with those of T-IMRT group, B-IMRT significantly improved the conformity and homogeneity of the target field (P < 0.05), and their mean dose of target field was similar. In addition, V₅, V₁₀, V₂₀, V₃₀ and D_mean of the left-side lung, and V₅, V₁₀, V₃₀ and D_mean of the heart in B-IMRT group were significantly reduced compared with those of T-IMRT group (P < 0.05). In comparison to those of T-IMRT, B-IMRT decreases V₅, V₁₀, V₂₀, V₃₀ and D_mean of the left-side lung by 9.23%, 13.29%, 9.54%, 8.28% and 10.35%, respectively, which decreases V₅, V₁₀, V₃₀ and D_mean of the heart by 27.62%, 29.72%, 21.45% and 24.88%, respectively. Conclusion Compared with T-IMRT planning, B-IMRT presents dosimetric advantages in the conformity and homogeneity of the target field in the postoperative radiotherapy of patients treated with modified radical mastectomy for left breast cancer, especially in reducing the radiation dose and volume of the heart and lungs.

Renal tubulointerstitial fibrosis is the common ending of progressive renal disease. It is worth developing new ways to stop the progress of renal fibrosis. Peroxisome proliferator-activated receptor-γ (PPARγ) agonists have been studied to treat diabetic nephropathy, cisplatin-induced acute renal injury, ischemia reperfusion injury and adriamycin nephropathy. In this study, unilateral ureteral obstruction (UUO) was used to establish a different renal fibrosis model. PPAR? agonist pioglitazone was administrated by oral gavage and saline was used as control. At 7th and 14th day after the operation, mice were sacrificed for fibrosis test and T lymphocytes subsets test. Unexpectedly, through MASSON staining, immunohistochemistry for α-SMA, and Western blotting for a-SMA and PDGFR-β, we found that pioglitazone failed to attenuate renal fibrosis in UUO mice. However, flow cytometry showed that pioglitazone down-regulated Th1 cells, and up-regulated Th2 cells, Th17 cells and Treg cells. But the Th17/Treg ratio had no significant change by pioglitazone. Real-time PCR results showed that TGF-β and MCP-1 had no significant changes, at the same time, CD4(+) T cells associated cytokines were partially regulated by pioglitazone pretreatment. Taken together, pioglitazone failed to suppress renal fibrosis progression caused by UUO.
