OBJECTIVE:To observe the efficacy and safety of carboprost and Foley catheter for the expand cervix before hys-teroscopic electric resection. METHODS:80 patients with hysteroscopic operation were randomly divided into research group and control group. Research group was placed inside the vagina carboprost 1 mg 30 minutes before operation;control group was placed inside the Foley catheter 12 hour before operation. The relaxation degree of the cervix,average operative time,preoperative pain, postoperative morbidity and incidence of adverse reactions in 2 groups were observed. RESULTS:There were no significant differ-ences in the relaxation degree of the cervix,postoperative morbidity and incidence of adverse reactions between 2 groups(P>0.05). The average operative time and preoperative pain in research group were significantly better than control group,the differ-ence was statistically significant(P<0.05). CONCLUSIONS:Carboprost and Foley catheter have good efficacy and safety for ex-pand cervix before hysteroscopic electric resection,however,carboprost is better than Foley catheter in terms of average operative time and preoperative pain.

Objective To investigate the effects of DRD1 rs265981,rs4532,rs686 and rs265976 polymorphisms on response to clozapine in resistant schizophrenic patients.Methods DRD1 genotype was determined by SNaPshot SNP technique for 154 patients with resistant schizophrenia.Clinical symptoms were evaluated by Positive and Negative Syndrome Scale (PANSS),and the responder was defined as a reduction of 50％ on PANSS score from baseline after the patients were administered orally clozapine for 8 weeks.Results The frequencies of rs265981 genotypes,alleles and rs265976 genotypes had significant differences between clozapine responder group (88 cases) and nonresponder group(66 cases) in total clinical efficacy ( x2 =10.215,P =0.004 ; x2 =4.082,P =0.041 ; x2 =14.083,P =0.007 ).The frequencies of rs265976 genotypes had significant differences between clozapine response (58 cases) and nonresponse (96 cases) to negative symptom ( x2 =9.805,P =0.046).Conclusion The polymorphisms of DRD1 gene rs265981 and rs265976 may relate with clinical response to clozapine in resistant schizophrenias.rs265981 T/T,allele T and rs265976 genotype A/A are likely to be predictive factors to the improvement of total clozapine therapeutic effects.rs265976 genotype A/A are likely to be predictive factors of negative symptom with treatment of clozapine.

Objective To explore the cytotoxicity of the cytotoxic T lymphocyte (CTL) induced by SW480 sonicate sensitized dendritic cells (DC) on the colon cancer cell line SW480. Methods PBMC were separated from the HLA-A*0201 donor and DC were cultured with rhGM-CSF, rhIL-4 and rhTNF-α. The same donor's primary CTL were stimulated by DC loaded with SW480 sonicate. The cytotoxicity of CTL on SW480 (HLA-A*0201 positive) and K562 (HLA-A*0201 negative) was determined by the MTT method. Results The cytotoxicity of the CTL on SW480 was stronger than that on K562 (P ＜0.05). Conclusion The DC vaccine can stimulate specific CTL which can trigger cytotoxic activity on the target cells and this cytotoxicity is related to MHC restriction.

Objective To study the expressions of metadherin (MTDH) and cyclinD1 in esophageal squamous cell carcinoma (ESCC) and their clinical significances. Methods The protein expressions of MTDH and cyclinD1 were detected by immunohistochemistry in 78 cases of ESCC. Results The positive expression rate of MTDH in ESCC was 71.79%(56/78) and the positive expression rate of cyclinD1 in ESCC was 74.36%(58/78). The expressions of MTDH and cyclinD1 were significantly correlated with the degree of differentiation and lymph node metastasis (both P< 0.05), but not with the age, gender of patients and depth of tumor invasion (all P> 0.05). Conclusion The over expressions of MTDH and cyclinD1 protein may involve in the occurrence and development of esophageal carcinoma, which play important roles in the invasion and metastasis of esophageal cancer.

The influence of exercise at high temperature on adult males' routine blood indexes and biochemical indexes and the expression of HSP72 in peripheral blood lymphocytes (PBLs) was studied in order to provide theoretical ground for health supervision of adults receiving exercise at high temperature. 180 adult males were selected and divided into exercise group and control group, in which the exercise group was subdivided into subgroup 1 and subgroup 2 receiving exercise at high temperature in the afternoon and in the morning, respectively. Peripheral venous blood was phlebotomized before and after the exercise to examine routine blood indexes and blood biochemical indexes. The expression levels of HSP72 in PBLs were detected by flow cytometry. The results showed that the routine blood indexes and biochemical indexes in each group were within the range of normal values of male adults. There was no significant difference between each exercise group and control group in indexes before exercise. After exercise, the expression levels of HSP72 in PBLs in exercise groups were higher than those before exercise, and HSP72 expression levels in subgroup 1 were obviously higher than those in subgroup 2 and control group. The contents of ALT, urea, Na+, Cl-, Ca2+ and K+ in subgroups 1 and 2 were lower than those in control group, but CK level was higher than in control group (P<0.05). The contents of Na+ and Cl- in subgroup 1 were relatively lower than those in subgroup 2 (P<0.05). It was concluded that while receiving exercise at high temperature, adult males' HSP72 levels in PBLs could be increased and the biochemical indexes changed. Attention should be paid to health supervision to avoid obvious body injuries at high temperature.

Objective To explore the clinical effect of free postnatal delivery in the second stage of labor, and to provide evidence for clinical midwifery. Methods From March 2016 to November 2017, 120 maternity patients from the First People′s Hospital of Hefei were selected and divided into research group and control group, using simple random grouping and the method of random number table, with 60 cases in each group. At the second stage of delivery, the research group used free body position at different stages, while the control group took the position of supine bladder lithotomy position. The delivery outcome, duration of the second stage, postpartum vaginal bleeding within two hours, newborn asphyxia rate, degree of perineal laceration, perineum incision rate, delivery comfort and satisfaction and midwives job satisfaction were compared. Results The vaginal delivery rate of the research group was 96.7％(58/60), which was higher than that of the control group 86.7％ (52/60). The difference was statistically significant (χ2=3.93, P<0.05). The duration of the second stage in the research group was (31.97 ± 9.85) minutes, and that of the control group was (39.50 ± 12.19) minutes. There was a statistically significant difference between the two groups (t=-3.357, P<0.05). There was no significant difference in neonatal asphyxia rate and the amount of postpartum vaginal bleeding within 2 hours between the two groups (P>0.05). The perineum integrity rate in the research group was 10.4％(6/58), higher than that in the control group, which was 0. Perineal side cut rate in the research group was 0, lower than that in the control group, which was 21.1％(11/52). The difference was statistically significant (χ2=11.31, 13.63, P<0.05). Deliverycomfort, delivery satisfaction and midwives job satisfaction in the research group were 91.7％ (55/60), 100.0％ (60/60) and 100.0％ (60/60) respectively, while delivery comfort, delivery satisfaction and midwives job satisfaction in the control group were 38.3％(23/60), 83.3％(50/60) and 76.7％(46/60). The differences were statistically significant (χ2=37.51, 10.91, 15.85, P<0.05). Conclusion The second labor stage free position is effective safe childbirth way of delivery, which can improve the natural births, shorten the labor, lighten the perineal injury, improve the puerpera childbirth comfort and satisfaction, it also raised the midwives job satisfaction, and had no adverse effect on maternal and infant outcomes, so the method has clinical application and dissemination value.

Background and purpose: It has been reported that epidermal growth factor receptor (EGFR) and epidermal growth factor receptor variant Ⅲ (EGFRv Ⅲ) play important roles in the progression of various cancers. This research was to detect the expression and relation of EGFR and epidermal growth factor receptor variant Ⅲ (EGFRv Ⅲ) to human esophageal carcinoma. Methods: In 66 human esophageal carcinoma tissues, the expression of EGFR and EGFRv Ⅲ were detected by imrnunohistochemistry and western-blot. The expression of EGFR and EGFRv Ⅲ along with the patients' clinicopathologic factors was retrospectively analyzed. Correlation analysis between EGFRv Ⅲ and EGFR was analyzed by Pearson correlation coefficient. Results: The average gray scale values of EGFR in esophageal carcinoma and normal tissues by immunohistochemistry were 25.4±3.2 and 5.0±3.5, which showed a significant difference (t=5.574, P=0.000). And the average gray scale values of EGFRv Ⅲ in esophageal carcinoma and normal tissues were 22.5±4.2 and 5.5±3.0, which also showed a significant difference (t=6.701,P=0.000). The average gray scale values of EGFR in esophageal carcinoma and normal tissues respectively by western-blot were 1.37±0.41 and 0.21±0.09, which showed a significant difference (t=10.704, P=0.000) And the average gray scale values of EGFRv Ⅲ respectively were 0.828±0.15 and 0.083±0.049, which had a significant difference (t=9.362, P=0.000). Significant differences were observed in TNM-stage, lymphatic metastasis and tumor classification in both the expression of EGFR (P<0.05) and EGFRv Ⅲ (P<0.05), and but there were no obvious differences in gender, age, minor size, growth pattern in both the expression of EGFR (P<0.05) and EGFRvⅢ (P<0.05). Correlation analysis showed that there was strong association of the expression between EGFR and EGFRv Ⅲ both detected by immunohistochemistry (r=0.701,P<0.0001) and western-blot respectively(r=0.556, P=0.031). Conclusion: Our data suggests that EGFRvⅢ is over-expressed in human esophageal carcinoma. Combination of EGFR and EGFRvⅢ could be useful markers for tumorgenesis and differentiation of human esophageal carcinoma.
