OBJECTIVEThe study aimed to review the treatment and prognosis of acute obstruction of colorectal cancers and to compare different treatment strategies of those cancers, and to evaluate the risk factors affecting perioperative complications.

METHODSClinical data of 184 patients with acute obstruction of colorectal cancer undergone operation were analyzed retrospectively.

RESULTSA total of 184 patients with acute obstruction of colorectal cancer was collected in this study, including 58 patients with proximal and 126 patients of distal colorectal cancers. Perioperative death occurred in 2/58 patients (3.4%) with distal colorectal cancer and 6/126 cases (4.8%) of distal colorectal cancer (P > 0.05). The overall perioperative complications in the two groups were not significantly different (P = 0.794). Among the 58 patients with proximal colorectal cancer, one patient underwent colostomy, but among the 126 patients with distal colorectal cancer, 41 patients underwent colostomy, showing a significant difference between the two groups (P = 0.002). ASA scores (grade 3 - 4), elderly age (≥ 70 years) and colon perforation peritonitis were independent prognostic factors associated with perioperative mortality and morbidity. Patients in the self-expandable metallic stent (SEMS) group had a significantly shorter hospital stay (25.4 ± 8.3) d than that in the emergency surgery group (32.8 ± 16.4) d, (P = 0.039).

CONCLUSIONSEndoscopic stent implantation provides an acceptable modality of palliation for acute proximal large bowel obstruction caused by malignancies. In acute colorectal cancer obstruction, SEMS can provide a minimally invasive management compared with surgical intervention.

Objective: To examine the expression of glucocorticoid receptor in human colon cancinoma tis-sues and call lines and to explore the survival of colon cancer cell lines treated with dexamethasone alone or in combination with 5-Fu and L-OHP in a way of dexamethasone pretreatment or co-administration in vitro.Methods: The expression of glucocorticoid receptor was detected in 61 cases of colon cancer tissue samples and 4 types of colon cancer cell lines by immunohistochemistry. Apoptosis was detected by Hoechst33342 staining and flow cytometry. MTT assay was employed to detect the chemosensitivity of colon carcinoma cells to L-OHP and 5-Fu with dexamethasone pretreatment for 24 hours or co-administretion. Results: Positive GR expression was found in 57.3% colon cancer tissue samples and in Lovo and HCT-116 cell lines, not in HT-29 and SW-480. Apoptosis was detected in GR-expressed Lovo and HCT-116 cells at 72 hours after 1×10~(-4)mol/L Dex treatment, and the rates of apoptosis were higher than those in the control groups without Dex (P<0.01),GR-negative cells, HT-29 and SW-480 even treated with 1 × 10~(-4)mol/L Dex for 72 hours. Pretreatment and co-administration for Lovo cells with 1×10~(-4)mol/L Dex could decrease the IC50 of L-OHP from 13.7±1:1.3μg/mL to 5.9±0.6μg/mL and 4.8±0.7μg/mL, respectively. IC50 of 5-Fu was decreased from 72.2±8.1 μg/mL to 21.1±4.1μg/mL and 18.6±4.0μg/mL, respectively. Conclusion: There is expression of glucocorticoid receptor in part of colon carcinoma tissue samples and cell lines. Apoptosis does occur in GR-expressed Lovo and HCT-116 cells induced by dexamethasone in vitro. Pretreatment for 24h and co-administration with Dex can increase the chemosensitivity of Lovo cells to L-OHP and 5-Fu.

Objective To investigate the value of magnetic resonance imaging(MRI)in the evaluation of microwave ablation(MA)for liver cancer.Methods The clinical data of 51 patients with liver cancer who received MA at the General Hospital of PLA from November 2005 to June 2009 were retrospectively analyzed.The MRI findings of 65 nodules before and after the treatment of MA were evaluated by serological examination and needle biopsy of liver.Results All patients received MRI within 1 month after MA.Of all nodules.63 were presented with high signal intensity on T_1-weighted images(T_1 WI)and low signal intensity on T_2-weighted images (T_2 WI)and with peripheral ring-like enhancement.They were diagnosed as complete coagulation necrosis,and the alpha-fetoprotein(AFP)level of the patients decreased from 333.83μg/L before MA to 37.68 μg/L after MA.Two nodules were presented with low signal intensity on T_1 WI and high signal intensity on T_2 WI,and they were diagnosed as local residual.All patients were followed up l month after MA,and 5 nodules showed enhancement with the same image characteristics as local residual.They were diagnosed as local recurrence of liver cancer by needle biopsy of liver and AFP level detection.New intrahepatic nodules in 23 patients and an abdominal nodule in 1 patient were detected with an increase of AFP level(mean,120.16 μg/L).Conclusion MRI Can exactly evaluate the efficacy of MA in the treatment of liver cancer.

OBJECTIVEThe aim of this study was to review the etiology and pathogenesis of patients who underwent surgery for mechanical bowel obstruction. The treatment and prognosis of bowel obstructions caused by intra-abdominal tumors were compared with those due to other causes.

METHODSThe clinical data of 203 patients with mechanical bowel obstruction undergoing operation were analyzed retrospectively. The tumor cases were classified as group I, and all other cases as group II. A range of factors were investigated to estimate the postoperative outcome: gender, age, comorbidities, symptoms and findings of physical and radiological examinations, sites of the obstruction, etiology, therapeutic approach, postoperative complications and mortality.

RESULTSGroup I included 73 patients and Group II 130. Large bowel carcinoma and peritoneal adhesions were the most common causes of Group I and II, contributing 58 and 86 of all cases, respectively. There was no significant difference in terms of gender between the two groups, but the rate of elderly (≥ 70 years) patients was significantly higher (53.4%) than that of the < 70 years old patients (35.4%) (P = 0.012). There was a significant difference between the patients with previous surgical operation history in the tumor group (23.3%) and non-tumor group (58.5%) (P < 0.001). In the 73 cases of the tumor group, the obstruction was located in the large bowel in 58 cases (79.5%), small bowel in 12 cases (16.4%), both small and large bowels in 2 cases (2.7%) and gastric cancer invading the splenic flexure of colon in 1 case, while in the non-tumor group, 111 cases (85.4%) of the obstruction was located in the small bowel and 19 cases (14.6%) and in the large bowel (P < 0.001). Sixty-six cases (90.4%) of the tumor-group underwent intestinal segment excision and 21 cases (28.8%) underwent intestinal fistulation in the tumor group, but in the non-tumor group 61 cases (46.9%) underwent intestinal segment excision and 5 cases (3.8%) underwent intestinal fistulation (all P < 0.001). The hospital stay was (18 ± 6) days in the tumor group and (11 ± 3) days in the non-tumor group (P < 0.01). The complication rate (P = 0.104) and mortality rate (P = 0.187) were not significantly different between the two groups.

CONCLUSIONSTumor mechanical bowel obstruction is more frequently seen in patients in elder age, with colorectal location and without previous operation history. CT scan may provide effective diagnosis and ascertain the presence of the malignant obstruction. Intestinal fistulation is more often needed in patients with tumor intestinal obstruction and endoscopic stenting is a safe option in selected patients with tumor intestinal obstruction.

Objective:To explore the feasibilitv of stereotactic minimally invasive aspiration of small thalamic bemorrhage.Methods:Twenty-two patients with small thalamic hemowhage(5 to 10 mL)were divided into two groups:a stereotactic group(n=10)and a control group(n= 12).The patients in the stereotactic group received stereomctic minimally invasive puncture and drainage of hematomas.According to the condition,repeated infusion of urokinase(10-20 kU) into the hematoma cavities were administered 12 hours after the procedure,and the hematomas were irrigated and drained so as to removal of them completely after retaining for 2-4 hours, The appropriate symptomatic treatment was administered in the patients in both groups.National Institutes of Health Stroke Scale(NIHSS)scores were determined 14 and 30 days before and after the treatment in all the patients.The reductiom of the NIJSS scores (as compared with those before treatment)were calculated at day 14 and 30 respectively after the treatment. Results:The reductiom of the NIHSS scores in the stereotactic group at day 14 and 30 were significantly higher than those in the control group.It was suggested that the neurological functional recovery of the patients was faster after stereotmtic minimally invasive puncture and drainage of intracranial hematorna in the stereotactic group.Concision:The stereotactic minimally invasive puncture and drainage of intracranial hematoma may significantly improve the outcome in patients with small thalamic hemorrhage.

Objective : To explore the relationship between alcohol consumption and hypertension in adults of Zhejiang Province, so as to provide scientific evidence for the prevention and control of hypertension. Methods: Data were collected from 10 national surveillance sites in Zhejiang Province in the 2018 China Chronic Disease and Risk Factors Surveillance. The multivariate logistic regression model was used to explore the relationship between alcohol consumption and hypertension in adults of Zhejiang Province. Results : Among 5 908 people included, 2 641 were males, accounting for 50.38%; and 3 267 were females, accounting for 49.62%. There were 2 721 cases of hypertension ( 28.54% ). The number of the cases with no, light and excessive alcohol consumption was 3 945, 1 117 and 846, accounting for 66.28%, 23.65% and 10.07%, respectively, after complex sampling weighting. The results of the multivariate logistic regression model showed that compared with those with no alcohol consumption, the adults with excessive alcohol consumption had higher risk of hypertension ( OR=2.126, 95%CI: 1.649-2.741 ); men with light ( OR=1.875, 95%CI: 1.075-3.270 ) and excessive alcohol consumption ( OR=2.752, 95%CI: 2.021-3.748 ) had higher risk of hypertension; the 18-<45-year-old adults with light ( OR=2.441, 95%CI: 1.171-5.087 ) and excessive alcohol consumption ( OR=3.368, 95%CI: 1.609-7.049 ), and the ≥60-year-old adults with excessive alcohol consumption ( OR=1.632, 95%CI: 1.174-2.269 ) had higher risk of hypertension. Conclusions Light and excessive alcohol consumption are associated with hypertension in Zhejiang adults. The association is stronger between excessive alcohol consumption and hypertension than between light alcohol consumption and hypertension.

Objective: To investigation the correlation between sleep duration and hypertension among adults in Zhejiang Province, and to provide scientific evidence for the prevention and control of hypertension. Methods: Permanent residents at age of 18 years and older were enrolled from 10 surveillance sites for risk factors of chronic diseases included in the 2018 China Chronic Diseases and Risk Factors Surveillance Program. Subjects' demographic characteristics, smoking, alcohol consumption, sleep duration and development of hypertension were collected, and following complex weighting calculations, the association between sleep duration and hypertension were examined using a multivariable logistic regression model. Results: Totally 5 770 adults were included, including 2 952 men (50.72%) and 3 178 women (49.28%), and the prevalence of hypertension was 29.39% (2 702 cases). There were 712 (8.37%), 1 077 (18.77%), 1 582 (28.68%), 1 717 (34.60%) and 682 adults (9.57%) with sleep duration of <6 h/d, 6 to 7 h/d, 7 to 8 h/d, 8 to 9 h/d and 9 h/d and longer, respectively. Taking the sleep duration of 7 to 8 h/d as a reference, multivariable logistic regression analysis identified a significant association between sleep duration of <6 h/d and the risk of hypertension (OR=1.709, 95%CI: 1.184-2.466), a significant association between sleep duration of 9 h/d and longer and the risk of hypertension (OR=1.369, 95%CI: 1.006-1.862) in men, significant associations between sleep duration of <6 h/d (OR=2.174, 95%CI: 1.528-3.093) and 6 to 7 h/d (OR=1.412, 95%CI: 1.078-1.850) and the risk of hypertension in women, and significant associations between sleep duration of <6 h/d (OR=3.095, 95%CI: 1.025-9.347) and 6 to 7 h/d (OR=2.046, 95%CI: 1.156-3.622) and the risk of hypertension in residents at ages of 18 to 44 years. Conclusions Short sleep duration may increase the risk of hypertension among adults at ages of 18 to 44 years in Zhejiang Province. Short sleep duration may increase the risk of hypertension in women and long sleep duration may increase the risk of hypertension in men.

OBJECTIVETo explore the feasibility and the related surgical techniques of laryngeal function preservation in surgical treatment of pyriform sinus cancer.

METHODSTwo hundred and thirty cases (stage I, 6; stage II, 10; stage III, 91; stage IV, 123) with pyriform sinus cancer were treated surgically from 1978 to 1996 in the Department of Otorhinolaryngology of Qilu Hospital of Shandong University. The methods of removing tumor and repairing surgical defects were depended on the extension of lesions. The laryngeal and pharyngeal functions were rebuilt by normal tissue preserved with lesions entirely removed. One hundred and fifty-eight cases were surgically treated with laryngeal functions preserved and 72 cases total laryngectomy. The most of the cases received postoperative radiotherapy.

RESULTSThe overall 3 and 5 year survival rates were 67.4% (155/230) and 48.3% (111/230) respectively. For stage I, the survival rate was 5/6; stage 11, 70.0% (7/10); stage III, 57.1% (52/91) and stage IV, 38.2% (47/123); the 3 and 5 year survival rates in functionally preserved group were 67.7% (107/158) and 50.0% (79/158), while in none functional group were 66.7% (48/72) and 43.1% (31/72), respectively. 75.3% (119/158) patients have laryngeal functions (voice,respiration and deglutition) completely restored and 24.7% (39/ 158) partially restored(voice and deglutition).

CONCLUSIONSThe preservative surgery is feasible for the selected pyriform sinus cancer cases. Choosing and following optimum surgical methods is a prerequisite for improving the quality of life of the cases.
