ABSTRACT
Objective To study the effect of Sildenafil in the treatment of hypoxemia after operation of cyanotic congenital heart disease.Methods A total of 34 cases with hypoxemia after operation of cyanotic congenital heart disease were collected between January 2009 to January 2015.They took Sildenafil with the dosage of 0.3-0.5 mg/kg every 6 hour.The change of heart rate (HR),systolic blood pressure (SBP),central venous pressure (CVP),pulmonary artery pressure (PAP),arterial partial pressure of oxygen [pa (O2)],arterial partial pressure of carbon dioxide [Pa (CO2)],oxygenation index [pa (O2)/FiO2],peak airway pressure (Ppeak),positive inotropic drug score (PIDS) and the lower bound of liver were observed at 4 time points,including before taking the medicine,after taking the medicine for 1 hour,after taking the medicine 1 day and after the ventilator was removed.Based on the data,the therapeutic effects of Sildenafil were studied.Results All 34 cases were cured.At the time point of 1 hour after taking Sildenafil,PAP,CVP and Ppeak decreased significantly,but pa (O2) and pa (O2)/FiO2 increased significantly (P ＜ 0.05).At the time point of 1 day after taking Sildinafil,SBP increased steadily,but PAP and CVP continued to get lower,and PIDS decreased significantly,while the liver lower bound was significantly reduced (P ＜ 0.05).At the time point of removing the ventilator,pa (O2) reached to (144.12 ± 26.25) mmHg,and hypoxemia was corrected,but PAP was reduced to (37.47 ± 3.77) mmHg,PIDS decreased to (17.56-± 1.94) scores,and heart failure was corrected.Compared with the previous 3 time points,there were statistically significant differences (P ＜ 0.05).Conclusion Sildenafil can highly selectively decrease pulmonary vascular resistance and obviously promote the correction of hypoxemia after operation of cyanotic congenital heart disease.
ABSTRACT
Objective To study the mutation of FLCN gene in Chinese patients with sporadic and familial primary spontaneous pneumothorax. Methods A complete genetic analysis of FLCN by use of SSCP-PCR was performed in 102 unrelated Chinese patients with isolated PSP. Results Three novel mutations (c. 924_926del, c. 1611_1631del and c. 1740C.T) and a previously reported mutation (c. 1733insC) were identified in five familial and five sporadic PSP patients. Of the 21 family members of patients with PSP including 3 previous considered as sporadic, 4 ( 19% ) had history of at least one episode of PSP and 9 (43% ) were FLCN mutant carriers without PSP. Seven of the nine (78% ) mutant carriers had pulmonary cysts detected by high-resolution computed tomography ( HRCT) . Although c. 924_926del and c. 1611 _1631 del were found in eight patients from the same geographic district, haplotype analysis demonstrated that they did not share the same affected haplotype,thus excluding common ancestry. Conclusion This study first demonstrates that FLCN mutation contributes to not only familial but also apparently sporadic' patients with isolated PSP. It suggests that mutation analysis and HRCT scan may be recommended for first-degree family members of PSP patients with FLCN mutations, irrespective of their family history status of PSP.
ABSTRACT
Cervical anastomosis by the thoracic approach for the treatment of upper esophageal cancer can simplify surgical steps and reduce incidence of anastomotic leak. This approach has been used for 26 patients with upper esophageal cancer who were admitted to the Jiangsu Cancer Hospital from July 2006 to August 2009. The mean length between lesion and incisor was 23.3 cm. General anesthesia and double-lumen intubation through left posterolateral incision in the fifth intercostal space was adopted. The stomach was dissociated with the technique of "in situ dissociation", and esophagus was dissociated conventionally. Double purse-string suture was adopted to fix the esophageal mucosa onto the supportive base of the stapler, and make purse-string suture to fix stomach on the center pole of the stapler. There was one failure case which has been converted to the manual cervical anastomosis, and the operations for the rest 25 cases were completed successfully, without anastomotic leakage and positive margin. The average blood loss was (352 ±211 )ml, and the average operation time was (3.7 ±0.6 )hours.
ABSTRACT
<p><b>BACKGROUND</b>To summarize the surgical treatment for locally advanced lung cancer invading heart and great vessels.</p><p><b>METHODS</b>One hundred and eighteen cases of lung cancer accepting cardiovascular plasty operation from 1980 to 2001 were reviewed.</p><p><b>RESULTS</b>The operations included partial resection of left atrium in 38 cases, pulmonary artery resection and restruction in 48 cases, replacement or partial resection of superior vena cava in 25 cases, partial resection of pulmonary conus in 3 cases, and lober replantation in 4 cases respectively. There was no perioperative death, and the 1-, 3-, 5- and 10 year survival rate was 72.68%, 55.20%, 28.62% and 20.36% respectively.</p><p><b>CONCLUSIONS</b>Cardiovascular plasty in the surgical treatment of locally advanced lung cancer invading heart or great vessels can remarkably increase the long-term survival and improve the life quality of the patients.</p>
ABSTRACT
Nutrients have an important role in the progression of digestive tract cancer.The progress is regulated by the aberrant DNA,apoptosis,et al.This review is about the associated genes of methylation,nutrients,and molecular regulating mechanisms in esophageal cancer.
