ABSTRACT

About 1/3 of patients with colorectal cancer have a genetic background. Familial colorectal cancer type X refers to colorectal cancer clinically in line with Amsterdam criteria Ⅱ, but genetic testing of which does not show microsatellite instability or DNA mismatch repair gene mutations. Its tumor cell gene is microsatellite stable. Attention should be paid to the differen-tiation from Lynch syndrome. Familial colorectal cancer type X is highly heterogeneous, without unclear etiology so far. It is recommended to refer to sporadic colorectal cancer for diagnosis, treatment, follow-up and prevention. The authors introduce the diagnosis and treatment of a case of familial colorectal cancer type X, in order to provide references for clinical diagnosis of this disease.

ABSTRACT

Objective: To explore clinical features and prognosis of anastomotic leak (AL) after anterior resection following neoadjuvant chemoradiotherapy for rectal cancer patients. Methods: A retrospective cohort study was performed. Data were retrieved from colorectal cancer database of the Sixth Affiliated Hospital, Sun Yat-sen University. The clinical data of 470 patients with rectal cancer who underwent anterior resection after neoadjuvant chemoradiotherapy at our department from September 2010 to December 2018 were enrolled. Clinical features and outcome of postoperative AL were analyzed. The primary outcomes were the short-term and long-term incidence and severity of AL (ISREC grading standard was adopted). The secondary outcomes were the prognostic indicators of AL, including the secondary chronic presacral sinus, anastomotic stenosis and persistent stoma. Patients received regular follow-up every 3-6 months after surgery, including physical examination, blood test, colonoscopy and image; those received follow-up once a year after postoperative 2-year; those who did not return to our hospital received telephone follow-up. Data of this study were retrieved up to January 2020. Univariate χ(2) test and multivariate logistic analysis were used to identify risk factors of AL and prognostic factors of persistent stoma. Results: There were 331 males (70.4%) with the average age of (53.5±11.6) years. Distance from tumor to anal verge ≤ 5 cm was found in 228 (48.5%) patients. The diverting stoma was performed in 440 (93.6%) patients. After a median follow-up of 28 months, AL was found in 129 (27.4%) patients, including 67 (14.3%) patients with clinical leak (ISREC grade B-C). The median time for diagnosis of AL was 70 days (2-515 days) after index surgery. Common symptoms included sacrococcygeal pain (27.9%, 36/129), purulent discharge through anus (25.6%, 33/129), and rectal irritation (17.8%, 23/129). Sixty five point one percent (84/129) of the defect site was at the posterior wall of the anastomosis. Transanal incision and drainage or lavage (27.9%, 36/129) and percutaneous drainage under ultrasound or CT (17.1%, 22/129) were the most common management. Chronic presacral sinus tract could not be evaluated in 12 patients because imaging was performed more than 1 year after the operation. Evaluation beyond 1 year showed that 73 of 458 eligible patients (15.9%) were found with chronic presacral sinus, accounting for 62.4% (73/117) of patients with AL; 69 of 454 (15.2%) were diagnosed with anastomotic stenosis, of whom 49 were secondary to AL; 59 of 470 (12.6%) had persistent stoma due to AL. Univariate analysis showed that male, operative duration > 180 minutes, intraoperative blood loss >150 ml, and pelvic radiation injury were associated with AL (all P<0.05). Multivariate analysis showed that male (OR=1.72, 95% CI: 1.04-2.86, P=0.036), intraoperative blood loss > 150 ml (OR=1.82, 95% CI: 1.11-2.97, P=0.017), and pelvic radiation injury (OR=4.90, 95% CI: 3.09-7.76, P<0.001) were independent risk factors of AL after anterior resection. For patients with AL, clinical leak (ISREC grade B-C) (OR=9.59, 95% CI: 3.73-24.69, P<0.001), age ≤55 years (OR=3.35, 95% CI: 1.35-8.30, P=0.009), distance from tumor to anal verge ≤ 5 cm (OR=3.33, 95% CI: 1.25-8.92, P=0.017), and pelvic radiation injury (OR=3.29, 95% CI: 1.33-8.14, P=0.010) were independent risk factors of persistent stoma. Conclusions: AL after anterior resection following neoadjuvant chemoradiotherapy for rectal cancer patients is common. Among patients with AL, the proportion of those needing persistent stoma is high. Pelvic radiation injury is significantly associated with occurrence of AL and subsequent persistent stoma. Sphincter-preserving surgery for rectal cancer should be selectively used based on the risk of pelvic radiation injury, which is beneficial to reduce the incidence of AL and improve the quality of life.

ABSTRACT

Aim To study the effects of daidzein on sodium channel current ( /Na) in ventricular myocytes of rats and the mechanism of its antiarrhythmia. Methods The effect of daidzein on the viability of ventricular myocytes was delected by MTT assay; single ventricular myocytes from rats were isolated by single enzymatic hydrolysis; the changes of /N, and its dynamic characteristics in rat ventricular myocytes before and after administration of daidzein were observed, recorded and analyzed by cell patch clamp technique. Results MTT experiments showed that the ICjo of daidzein was 30 to 100 jjimol • L"1 ,so the concentration of 0. 3 - 10 jimol • L"1 was chosen for the subsequent experiments. When daidzein was given 0. 3,1,3,10 pjnol • L"',the /Nb amplitude of ventricular myocytes in rats showed a concentration-dependent inhibition. The concentration of daidzein 0. 3 imol • L"1 also had certain effect on the time course of /Nt. The /Nl, peak decreased gradually over time. The 1,3,10 jimol • L"1 daidzein raised the I-U curve obviously. Under the same condition, the activation curve moved to the direction of depolarization. The steady-state inactivation curve shifted toward hyperpolarization, and the t value of the recovery curve was prolonged after inactivated state. Conclusions Daidzein significantly inhibited the Na∗ channel of ventricular myocardium in rats, which may l)e one of its mechanisms of anti-arrhythmia.

ABSTRACT

Background:Small intestinal bleeding is difficult to diagnose and treat because of its complex etiology and limit to examination method. Aims:To analyze the etiology,diagnosis,treatment and prognosis of small intestinal bleeding. Methods:The clinical data of 118 consecutive patients with small intestinal bleeding admitted from Oct. 2006 to Oct. 2016 at Daping Hospital,the Third Military Medical University were retrospectively analyzed. Results:Melena was the most common manifestation of small intestinal bleeding (41. 5%),followed by dark bloody stool,positive fecal occult blood test,hematochezia,and anemia with unknown cause. The major causes of bleeding were benign or malignant tumors (43. 2%),vascular lesions (28. 0%)and inflammatory lesions (15. 3%). Diagnosis was made by means of capsule endoscopy,colonoscopy,digital subtraction angiography (DSA),barium meal examination,multi-slice CT (MSCT)and CT enterography (CTE). Forty-one patients were treated by surgical operation,7 by selective arterial embolization,2 by endoscopic therapy,56 by conservative therapy,and all these patients achieved hemostasis. One patient died of massive hemorrhage and 11 were discharged with giving up of treatment. Conclusions:The leading cause of small intestinal bleeding is tumor,followed by vascular and inflammatory lesions. Capsule endoscopy is able to make definite diagnosis with high accuracy,and MSCT is the most widely used diagnostic approach. In addition to conventional treatment,surgical operation,interventional and endoscopic therapies also play important roles in treating small intestinal bleeding.

ABSTRACT

To investigate the effects of isovitexin Ⅳ on transient outward potassium current in rat ventricular myocytes. In this study, MTT assay was used to investigate the safe range of isovitexin. The results showed that the IC₅₀ of the drug was in the range of 10-30 μmol•L⁻¹, and the drug concentration of 1-3 μmol•L⁻¹ for the patch clamp test was within the safe range. In addition, the single ventricular myocytes were obtained by single-enzymatic hydrolysis through aortic retrograde perfusion. The transient outward potassium current (Ito) of rat ventricular myocytes was guided and measured by whole-cell patch-clamp technique and the changes of current characteristics were recorded after isovite was applied. When the concentration of IV was less than 0.1 μmol•L⁻¹, there was no significant effect on Ito. However, with the increase in the concentration of IV (≥0.3 μmol•L⁻¹), the peak of Ito was decreased gradually, from (32.32±2.9) pA/pF to (25.83±4.3) pA/pF, 1 μmol•L⁻¹ IV and (19.51±3.5) pA/pF, 3 μmol•L⁻¹ IV respectively, with an inhibition effect in a concentration-dependent manner. In the range of 1-3 μmol•L⁻¹, IV down-regulated the I-V curve of Ito significantly. The activation curve showed that IV can enable the maximum half activation potential (V1/2) to move to the positive direction, and the V1/2 was increased from (19.59±1.6) mV to (22.81±1.7) mV and (28.86±1.4) mV at concentration of 1, 3 μmol•L⁻¹, meanwhile the activation curve moved to the right. However, the maximum half inactivating potential (V1/2) of the steady-state inactivation curve of Ito was significantly decreased from (-51.43±0.99) mV to (-61.81±1.3) mV with concentration of 1 μmol•L⁻¹ and (-71.50±1.4) mV with concentration of 3 μmol•L⁻¹. The inactivation time constant of recovery from inactivation (τ) was up-regulated significantly from (94.89±0.73) ms to (118.5±1.5) ms and (162.4±1.4) ms at concentration of 1, 3 μmol•L⁻¹ respectively. Meanwhile IV could enable the inactivation recovery curve to move to the right, which suggested that it can prolong the recovery time from inactivation of the transient outward potassium channel. In conclusion, isovitexin had a high inhibitory effect on Ito in rat ventricular myocytes.
