Objective To analyse the affecting factor of iatrogenic preterm labor and the prognosis of premature infants. Methods 44 cases of iatrogenic preterm labor and 64 cases of preterm labor of caesarean section because of/in our hospital other reasons from 1998 to 2001 were enrolled in this study. The risk factors of the two groups of pregnant woman and the prognosis of their premature infants were analyzed. Results Iatrogenic preterm labor was related with multiple factors. Regular antenatal care and proper treatment may get a better pregnant result in the inevitable iatrogenic preterm delivery. Conclusion Selective caesarean section and intensive care after birth will reduce the complications and the mortality of the premature infants.

Ninety elderly patients with coronary heart disease were randomly divided into 2 groups:in study group (n = 45) the cognitive-behavioral intervention as well as conventional medical treatment were performed and in control group ( n = 45 ) only conventional treatment was given. Short Form-36 ( SF-36),symptom checklist 90(SCL-90), Hamilton anxiety scale( HAMA), Hamilton depression scale( HAMD)were evaluated before and after intervention, the serum total cholesterol (TC), triglyceride (TG)and body mass index (BMI)were measured, the smoking and drinking behaviors were recorded. After 6-month of intervention the smoking [(0. 6 ± 0. 2)cigarettes/d] and drinking [(10. 1 ± 2. 3)g/d] behaviors, the scores of SF-36 (85 ± 16), SCL-90 (104 ±4), HAMA (10 ±4) and HAMD (12 ±3), the systolic blood pressure [( 123 ± 11 ) mm Hg ( 1 mm Hg = 0. 133 kPa)], diastolic blood pressure [(77 ± 5 ) mm Hg], the fasting blood glucose [(4. 2 ± 2. 6 ) mmol/L] and BMI ( 22.5 ± 0. 5 ) in study group were significantly improved compared to control group ( P ＜ 0. 01 ). The results indicate that cognitive-behavioral intervention can improve the mental state and quality of life in elderly patients with coronary heart disease.

Objective To explore the effects of behavioral intervention on mental heath and quality of life of inpatients with coronary heart disease. Methods Eighty cases with coronary heart disease were randomly divid-ed into intervention group(n=40) and the drug treatment group(n=40). SF-36,SCL-90,EPQ,HAMA,HAMD were applied to assess the mental health state and quality of life. Results After 6-months, the score of SF-36,SCL-90,EPQ,HAMA, HAMD,and N score of EPQ in intervention group were more significantly proved than the drug treatment group SF-36:(84.7±16.2)vs(68.3±10.6); P <0.01; SCL-90:(83.5±4.2)vs(148.6±3.2)], P<0.05;EPQ-N:(43.8±4.2)vs(52.8±3.1), P<0.01;HAMA:(10.4±3.4)vs(15.1±5.1), P <0.01; HAMD: (11.4±3.8) vs (17.9±4.6), P< 0.01). Conclustion Behavioral intervention effectively im-proves mental state and quality of life of patients with coronary heart disease.

Activity of IL-1 produced by peripheral blood monocytes stimulated with lipopolysaccharide in vitro was detected from 17 acute cases, 14 chronic cases and 19 advanced cases of schistosomiasis japonica. It was found that the level of IL-1 was significantly increased and positively related to the body tempereture in the group with acute schistosomiasis. The activity of IL-1 was statistically reduced in the chronic and advanced groups, especially in the latter. After inhibiting the synthesis of prostaglandin with indomethacin, the level of IL-1 was significantly increased in three groups of patients, but no apparent change in the normal contro group. The results indicate that IL-1 may play an important role in inducing the inflammatory reaction in patients with acute schistosomiasis japonica and in the immunoregulation in the chronic stage. The changes of IL-1 activity in patients with schistosomiasis japonica may be closely related to prostaglandin.

Objective: To detect the level of peripheral blood UL16 binding protein 2 (ULBP2) in patients with colorectal cancer, and study its value on early diagnosis and prognosis evaluation. Methods: Eighty patients with colorectal cancer (colorectal cancer group) and 60 healthy subjects (healthy control group) from May 2016 to May 2019 in Affiliated Dongfeng Hospital, Hubei University of Medicine were selected. Serum expression level of ULBP2 was detected by enzyme-linked immunosorbent assay. The diagnostic efficacy of serum ULBP2 in colorectal cancer was evaluated by receiver operating characteristic (ROC) curve. The influencing factors of survival in patients with colorectal cancer were analyzed by Cox regression model. Kaplan-Meier method was used for drawing the survival curve, and log-rank test method was used for comparison. Results: The serum ULBP2 level in colorectal cancer group was significantly higher than that in healthy control group: (85.52 ± 12.18) ng/L vs. (66.20 ± 8.28) ng/L, and the serum ULBP2 level of stage Ⅰ to Ⅱ in colorectal cancer group was also significantly higher than that in healthy control group: (76.44 ± 7.56) ng/L vs. (66.20 ± 8.28) ng/L, and there were statistical differences (P<0.05). ROC curve analysis result showed that the optimal cut off value of serum ULBP2 for colorectal cancer diagnosis was 79.53 ng/L, and area under curve (AUC) was 0.869, with a sensitivity of 73.75% and a specificity of 91.67%; the optimal cut off value of serum ULBP2 for stage Ⅰ to Ⅱ colorectal cancer diagnosis was 71.86 ng/L, and AUC was 0.827, with a sensitivity of 78.57%, and a specificity of 78.33%. According to the median serum ULBP2 level, the patients were divided into ULBP2 high expression (ULBP2>85.52 ng/L, 38 cases) and ULBP2 low expression (42 cases). The serum expression level of ULBP2 was related to lymph node metastasis and tissue differentiation (P < 0.05). Univariate Cox regression analysis result showed that lymph node metastasis, distant metastasis, tissue differentiation and serum ULBP2 were risk factors of poor prognosis in patients with colorectal cancer (P<0.01 or <0.05); multivariate Cox regression analysis result showed that serum ULBP2 was the independent risk factor of poor prognosis in patients with colorectal cancer (HR = 0.194, 95% CI 0.077 to 0.490, P = 0.001). The median survival time in patients with serum ULBP2 high expression was significantly shorter than that in patients with serum ULBP2 low expression (28 months vs. 50 months), and there was statistical difference (P<0.05). Conclusions Serum ULBP2 can be used as an indicator for early diagnosis and prognostic evaluation in patients with colorectal cancer.

Objective To compare the clinical effects of RPH combined with Milligan and PPH in the treatment of severe mixed hemorrhoids. Methods 168 patients with severe mixed hemorrhoids were assigned to a study group or a control group,84 patients for each group. The control group received PPH therapy,while the study group received RPH combined with Milligan procedure. Results The procedures were completed successfully in all the patients. The postoperative hospital stay and surgical duration were shorter and the amount of bleeding was smaller in the study group than in the control group(P<0.05). Three months after surgery,the rate of compli-cations including urinary retention,anal incontinence,anorectal stenosis,and secondary anal fissure was lower in the study group than in the control group(P < 0.05). The total effective rate was 97.6% in the study group and 85.7% in the control group,with a higher rate in the study group(P<0.05). Anal PSV and EDV values were lower in both groups three months after the procedures as compared with one day before the procedures(P<0.05),and the values were smaller in the study group than in the control group(P<0.05). Conclusions Milligan combined with RPH in the treatment of severe mixed hemorrhoids can reduce hemorrhoids blood flow. This procedure is mini-mally invasive and it can reduce the development of postoperative complications and improve efficacy.
