Objective:To elucidate the factors influencing the differences in the survival rates of esophageal squamous cell carcinoma (ESCC) patients between the rural and urban regions in China. Methods:A total of 36,723 ESCC patients derived from the clinical data-bases containing 500,000 esophageal and gastric cardia carcinoma cases (1973-2015) of the Henan Key Laboratory for Esophageal Can-cer Research of the First Affiliated Hospital, Zhengzhou University, were analyzed. Of these patients, 33,625 were from the rural re-gions (91.6%), comprising 20,906 male patients with an average age of 58.98 ± 8.71 years and 12,719 females with an average age of 59.59 ± 8.53 years. The remaining 3,098 were from the urban regions and composed of 2,089 male patients with an average age of 60.84±9.10 years and 1,009 females with an average age of 62.46 ± 9.14 years. All the patients underwent radical esophagectomy, de-tailed histopathological diagnosis, and TNM staging. Chi square test, Kaplan-Meier, Log-rank, and Cox proportional hazards regression model were used to analyze the differences between ESCC patients from rural regions and those from urban regions and among the risk factors in prognosis. Results:Kaplan-Meier and Log-rank analysis results showed that the ESCC patients from the rural regions had significantly higher overall survival than the urban patients (χ2=12.971, P=0.000). Further analysis showed that rural patients≥50 years old and diagnosed with stage IIa and IIb (middle stage) ESCC had higher survival rates than urban patients in males and females (male:χ2=16.188, P<0.001;female:χ2=5.019, P=0.025). However, the survival rates of rural and urban patients with stage 0,Ⅰa,Ⅰb (early stage) and Ⅲa, Ⅲc, and Ⅳ (late stage) were similar (P>0.05). The results of Cox proportional hazards regression model analysis showed that age, gender, and TNM stages were independent risk factors for rural and urban ESCC patients. When the rural and urban ESCC patients were both considered, the Cox proportional hazards regression model analysis results showed that male ESCC patients≥50 years old, urban residence, and TNM stages were independent risk factors. Conclusion:Rural ESCC patients have significantly high-er overall survival than urban patients. Male, age of≥50 years old, urban residence, and TNM stages were independent risk factors for ESCC patient survival.

Objective: The present study aims to summarize the clinical experience in the surgical treatment of thoracic aortic dissecting aneurysm.Methods: We retrospectively analyzed the clinical data of 115 cases of thoracic aortic dissecting aneurysm treated by surgery from December 1995 to December 2006.Thirty-eight of them were DeBakey type I aortic dissection,18 type Ⅱ,and 59 type Ⅲ.Of the 38 DeBakey type I patients,30 underwent ascending aorta with total aortic arch replacement(2 cases of total thoracic aortic artificial vessel replacement,25 Wheat procedure and 3 aortic valvuloplasty) and the other 8 received ascending aorta with semi-aortic arch replacement.Of the 59 DeBakey type Ⅲ patients,36 underwent descending aortic aneurysm resection with artificial vessel replacement via left posterolateral thoracic incision by left heart bypass or aorta to artery bypass(using Cott tubes),while the other 23 received endovascular stent-graft exclusion in descending aorta via the femoral artery.Results: All the patients were successfully treated except 5 that died during the perioperative period.The survivors were followed up for 3-118 months,among whom 2 died long-term death after the operation and the others were living healthy.Conclusion: Surgical treatment improves the clinical outcome of thoracic aortic dissecting aneurysm.Bilateral perfusion via the carotid artery in aortic arch replacement has a definite cerebral protective effect.Surgical procedures can be simplified by using the modified elephant trunk technique.Endovascular stent-graft exclusion is safe and effective in the treatment of DeBakey type Ⅲ aortic dissection.

Objective:To explore the application value in cerebral blood perfusion status of dynamic susceptibility contrast enhanced perfusion weighted imaging (DSC-PWI) in ischemic cerebrovascular disease (ICVD).Methods:Retrospective analysis of 31 cases ICVD head magnetic resonance imaging (MRI), diffusion weighted imaging (DWI), magnetic resonance angiography (MRA) and DSC-PWI image in clinical diagnosis, and selectively analyze parameters including relative cerebral blood flow (rCBF), relative cerebral blood volume (rCBV), mean transit time (MTT) and time to peak (TTP) for generalize its characteristics.Results:31 cases of ICVD, 16 cases hypoperfusion, rCBF decreased significantly, rCBV decreased, MTT and TTP prolonged, include 7 cases of large vessel disease and 5 cases of small vessel disease. The collateral circulation formed 9 cases, including 3 cases with good compensation, rCBF normal, rCBV normal, MTT and TTP prolonged, 6 cases with bad compensation, rCBF decreased, rCBV normal or increased, MTT and TTP prolonged. The blood reperfusion in 3 cases, rCBF normal or slightly increased, rCBV increased, MTT shortened or normal, and TTP shortened. The excessive perfusion in 3 cases, rCBF significantly increased and rCBV significantly increased, with MTT and TTP shortened.Conclusions:DSC-PWI can reliably reflect the perfusion state and collateral circulation compensation of ICVD, so as to guide the selection of clinical treatment program and significantly improve the prognosis of patients.

Objective To analyze the efficacy and safety of tetrandrine in the adjuvant treatment of relapsed/refractory acute leukemia (except M3).Methods A total of 58 patients with relapsed/refractory acute leukemia (except M3) admitted to six tertiary hospitals in Jiangsu Province from January 2015 to December 2017 were included in this study.The tetrandrine-adjuvant standard chemotherapy regimen and standard chemotherapy regimen were given to treatment and control groups respectively.There were 17 and 41 patients in treatment and control groups.The treatment group was given tetrandrine for 5 days before the use of standard chemotherapy.The dose of tetrandrine was 4 mg ·kg-1 ·d-1,and patients had continuous oral administration of 5 days.After that,the patients in the treatment group started chemotherapy immediately.On the other side,the control group received standard chemotherapy without any other multidrug reversal medicine.Then the clinical efficacy and safety outcomes in both groups were analyzed.Results In the treatment group,5,3,and 9 cases achieved complete remission (CR),partial remission (PR),and nonremission (NR) respectively,and the total effective (CR+PR) rate was 47.06 ％ (8/17);in the control group,14,10,and 17 cases achieved CR,PR,and NR,and the total effective rate was 58.54 ％ (24/41).There was no significant difference in the total effective rate between the two groups (x2 =0.64,P =0.424).There was no significant difference in the efficacy between the two groups of patients with different genders (P ＞ 0.05).When the disease duration was 6-11 months,the difference of efficacy between the two groups was statistically significant (P =0.041).There was no significant difference in the proportion of myeloid leukemia cells,white blood cell count,platelet count,red blood cell count,and hemoglobin between the two groups before and after treatment (all P ＞ 0.05).There was no significant difference in clinical safety indicators (urine,faecal routine,liver and kidney function,and electrocardiogram) between the two groups (all P ＞ 0.05).Conclusions Tetrandrine is more effective in patients with relapsed/refractory acute leukemia (except M3) with shorter duration of disease.Compared with chemotherapy alone,the clinical efficacy of adding tetrandrine in chemotherapy cannot be considered superior to the former.

Objective:To explore the clinical features, surgical treatments and treatment effects of children with skull defect.Methods:Sixty children with skull defect, admitted to our hospital from January 2010 to December 2020, were chosen in our study. These children were divided into encephalocele group ( n=28) and non-encephalocele group ( n=32) according to the imaging results (whether brain tissues were 1.5 cm higher than the bone window plane or not). The time and area of skull defect were compared between the two groups. Titanium mesh or polyether ether ketone material were used to repair the skull defect; 24 children without nerve fiber bundle distribution from encephalocele group underwent resection of the encephalocele tissues additionally. All children were followed up for 3-10 years in the outpatient department, and the prognoses of children from the two groups were evaluated by Glasgow Outcome Scale (GOS) one year after surgery. Results:As compared with the non-encephalocele group, children in the encephalocele group had significantly younger age accepted skull removal, significantly longer skull defect course, significantly higher incidence of epilepsy, significantly more common secondary changes in the brain tissues around the defect, but statistically smaller skull defect area ( P<0.05). There was no bleeding, severe edema, wound infection or cerebrospinal fluid leakage after surgery in both groups, and primary healing was achieved. In the encephalocele group, 16 children were complicated with epilepsy; 10 got complete seizure control, and 6 got seizure improvement. In the non-encephalocele group, 8 children were complicated with epilepsy; 6 got complete seizure control, and 2 got seizure improvement. Postoperative follow-up showed that GOS scores in the non-encephalocele group were significantly higher than those in encephalocele group ( P<0.05). Conclusion:As ompared with skull defect children without encephalocele, skull defect children with encephalocele have earlier defect age, longer course of disease, higher incidences of ventricular perforation malformation and epilepsy, and a relatively poorer prognosis.
