OBJECTIVETo analyze the mutations of the RUNX2 gene in a family with cleidocranial dysplasia (CCD).

METHODSThe general health status of family members with CCD was investigated through propositus verification method. Oral specialized examination and radiological examination were performed. The peripheral venous blood of the proband and her parents and sisters was collected. Genomic DNA was extracted, and the RUNX2 gene from this DNA was amplified by polymerase chain reaction (PCR). DNA sequences were analyzed with the Blastn program.

RESULTSAfter Blastn analysis, heterozygous C to T transition mutation at nucleotide 568 occurred in exon 2, which converted arginine to tryptophane at codon 190 (c.568C>T, CGG-->TGG).

CONCLUSIONRUNX2 gene is responsible for the CCD in the Chinese family under study. The c.568C>T mutation is the molecular basis of the CCD in the family.

At present,surgery is still the best way to treat resectable non-small cell lung cancer (NSCLC).For clinicians,TNM stage is the main indicator to judge surgical outcomes,but the prognosis of patients with same stages still has big differences.The related studies have shown that the prognostic factors for patients with NSCLC after surgical treatment include poor lung function,the suffering from cardiovascular diseases,male,advanced age,comorbidities,advanced TNM stage,non-adenocarcinoma and pneumonectomy.Many results of prognostic factors research are controversial;meanwhile,the effects of molecular biological factors,neoadjuvant therapy and adjuvant therapy on prognosis still need further study.

Objective: To explore the value of the constructed prognostic prediction model of resectable lung cancer in predicting the survival and prognosis of patients. Methods: A total of 2 267 patients with primary lung cancer in Shanxi Provincial Cancer Hospital from January 2007 to September 2018 were selected. All patients underwent primary lung cancer surgery without a second primary tumor. Gender, age, occupation, tumor site, pathological type, surgical path, surgical method, tumor stage and treatment were selected as the prognostic factors. A Cox proportional hazard model was used to construct a prognostic index (PI) equation to calculate the PI value of each patient. According to the different ranges of PI values, the low-, intermediate- and high-risk prognosis groups were divided, and the survival status of three groups were evaluated. Results: Gender (RR= 0.684, P= 0.001), age (RR= 0.591, P < 0.01), occupation (RR= 1.439, P= 0.001), pathological type (RR= 3.694, P < 0.01), surgical path (RR= 0.734, P= 0.001), tumor stage (RR= 0.352, P= 0.007) were independent factors affecting the prognosis of patients with resectable lung cancer. Female, ≤65 years old, thoracoscopic surgery, and tumor stage Ⅰ were prognostic protective factors, and their risks of poor prognosis were reduced by 31.6%, 40.9%, 26.6%, and 64.8%, respectively. Farmer and adenosquamous carcinoma were prognostic risk factors, and their risks of poor prognosis were increased by 43.9% and 269.4%, respectively. The PI equation was ∑β_ix_i=-0.380 X₁-0.526 X₂+0.364 X₃₁+1.307 X₅₅-0.309 X₆-1.045 X₈₁ (X₁ was the gender, X₂ was the age, X₃₁ was the occupation as a farmer, X₅₅ was the pathological type of adenosquamous carcinoma, X₆ was the surgical path, X₈₁ was the tumor stage Ⅰ). PI <-1 was the low-risk group, PI ≥-1 and ≤-0.5 was the intermediate-risk group, PI >-0.5 was the high-risk group, and the differences of their survival rates were statistically significant (P < 0.05). The 1-, 3-, and 5-year survival rates for the low-, risk groups were 96.8%, 87.0% and 77.9%; the intermediate-risk group were 91.8%, 82.2% and 61.7%; the high-risk group were 86.5%, 61.7% and 50.3%. respectively. Conclusion The prognostic prediction model of resectable lung cancer can predict the prognosis risk and the corresponding survival rate of patients with resectable lung cancer, and it can help clinicians to evaluate the prognosis and formulate subsequent treatment plans.

Objective To evaluate the clinical diagnostic application and operative efficacy of the expression of NKG2D in peripheral blood CD+8 NKT cell and its ligand sMICA in patients with esophageal or cardiac carcinoma.Methods The peripheral blood NKG2D positive CD+8 NKT cell percentage was concomitantly determined by flow cytometry in 53 preoperative patients including 29 postoperative patients with esophageal or cardiac carcinoma and 30 healthy controls.The serum sMICA was determined by ELISA.Results The peripheral blood NKG2D positive CD+8 NKT cell percentage in patients was significantly lower than that in controls [(77.632±8.972) % vs (89.053±6.515) %] (t = -6.113,P ＜0.05); with stage Ⅱ,Ⅲ,Ⅳ,it decreased significantly in order (F = 99.251,P ＜0.01);with lymph node metastasis lower than that without lymph node metastasis (t = -10.384,P ＜0.01); squamous carcinoma was higher than adenocarcinoma (t =9.899,P ＜0.01); postoperative was significantly higher than preoperative (t =-4.319,P ＜0.01).The level of serum sMICA in patients was significantly higher than that in controls [(326.28±85.407) pg/ml vs (210.00±92.560) pg/ml](t =7.292,P ＜0.01); with stage Ⅱ,Ⅲ,Ⅳ,it increased significautly in order (F =63.355,P ＜0.01); with lymph node metastasis higher than that without lymph node metastasis (t =7.770,P ＜0.01); squamous carcinoma was lower than adenocarcinoma (t =-7.593,P＜0.01); postoperative was significantly lower than preoperative (t =7.027,P ＜0.01).Serum sMICA could inhibit peripheral blood CD+8 NKT cell activation receptor NKG2D (F =142.773,P ＜0.05),determination coefficient R2 = 0.7368.Conclusion The level of peripheral blood CD+8NKT cell activation receptor NKG2D and serum sMICA in patients could be an assistant indicator for

Objective To investigate the application of bundles of intervention in the treatment of postoperative delirium in esophageal cancer.Methods Thirty-six cases of delirium associated with esophageal cancer(study group)after the application of bundles of intervention in the Affiliated Huaian No.1 People's Hospital of Nanjing Medical University from November 2015 to August 2016 were analyzed,and 41 cases of postoperative delirium(control group)from January 2015 to October 2015 were treated by routine treatment.Results The mean duration of postoperative delirium was(3.6±0.8)d in the study group and(4.7± 1.2)d in the control group,and the difference was statistically significant(t =4.783,P<0.01).The incidence rates of other complications in the study group and control group were 19.4％(7/36)and 34.1％(14/41),respectively,and there was no significant difference(χ2=2.089,P=0.148).The incidence rates of accidental events in the study group and control group were 13.9％(5/36)and 31.7％(13/41),respectively,and the difference was statistically significant(χ2= 4232,P= 0.040).There was no significant difference in the postoperative exhaust time and removal of chest tube drainage time between the two groups(both P＞ 0.05),but there was a significant difference in postoperative hospital stay and hospital costs between the two groups(t values were 4.726 and 2.065,both P<0.05).Conclusions In the treatment of postoperative delirium in esophageal cancer,applying the bundles of intervention concept is feasible and effective.It can significantly reduce postoperative delirium duration and accelerate the rehabilitation of patients.

Objective:To investigate the clinical application value of radiochemotherapy conversion therapy in unresectable locally advanced esophageal cancer.Methods:A total of 298 patients with unresectable locally advanced esophageal cancer who received radiochemotherapy with or without surgery from 2010 to 2016 were screened in the U.S. Surveillance, Epidemiology, and End Results (SEER) 18 oncology database, and the patients were divided into the conversion therapy group (received surgery after radiotherapy, 83 cases) and the radiochemotherapy group (215 cases) according to whether they were operated after radiotherapy. A 1∶1 propensity matching analysis was conducted on the two groups of patients using R language. The information of age, gender, race, T stage, G stage, pathological type and N stage of the patients in the two groups before and after matching was compared. The Kaplan-Meier method was used for survival analysis to compare the cancer specific survival and overall survival (OS) between the two groups before and after matching. A multivariate Cox proportional hazards model was used to analyze the influencing factors of prognosis of patients with unresectable locally advanced esophageal cancer.Results:There were statistically significant differences in gender, race, G stage, pathological type, T stage, and N stage between the conversion therapy group and the radiochemotherapy group before matching (all P < 0.05). There was no statistically significant difference in clinicopathological characteristics between the conversion therapy group and the radiochemotherapy group after matching (all P > 0.05). Before matching, the median OS time of patients in the conversion therapy group was 23 months; the 1-year, 2-year, 3-year, and 5-year OS rates were 68.9%, 42.9%, 24.7%, and 19.8%, respectively; the 1-year, 2-year, 3-year, and 5-year cancer specific survival rates were 68.9%, 45.0%, 28.0%, and 28.0%, respectively. The median OS time of patients in the radiochemotherapy group was 12 months; the 1-year, 2-year, 3-year and 5-year OS rates were 44.5%, 20.5%, 14.0%, and 6.0%, respectively; the 1-year, 2-year, 3-year and 5-year cancer specific survival rates were 46.4%, 21.8%, 14.9%, and 9.1%, respectively. Compared with the radiochemotherapy group, patients in the conversion therapy group had a better cancer specific survival ( χ2 = 15.01, P = 0.001) and OS ( χ2 = 14.85, P < 0.001). After matching, cancer specific survival ( χ2 = 5.06, P = 0.024) and OS ( χ2 = 6.12, P = 0.013) of the conversion therapy group were still superior to the radiochemotherapy group. The results of multivariate Cox regression analysis showed that the cancer specific survival risk and overall survival risk in the radiochemotherapy group were 1.874 times (95% CI 1.275-2.755, P = 0.001) and 1.790 times (95% CI 1.235-2.593, P = 0.002) higher than those in the conversion therapy group. Conclusions:Radiochemotherapy conversion therapy can improve the prognosis of patients with unresectable locally advanced esophageal cancer.
