Objective To observe the short-term clinical efficacy of modified transanal Soave surgery on infants with hirschsprung′s disease (HD) in initial radial resection, and to analyze the influencing factors. Methods 132 HD infants were selected. After initial radial resection with modified transanal , Soave surgery was conducted under general or sacral anesthesia. Postoperative antibiotics were routinely given. Results 19-56 cm intestinal canal samples were excised, with average length of (35.07 ± 3.15) cm. The average surgical duration and intra-operative hemorrhagic volume were (120.48 ± 18.34) min and verage was (45.74 ± 8.14) mL. All infants′ gastrointestinal function was recovered in 24 h postoperatively. The total excellent and effective rate of anal function in 6 months was 90.90% postoperatively. Cox modal multivariate analysis suggested that anastomotic orifice stenosis and enteritis were the two factors that greatly influenced the excellent and effective rate of anal function 6 months after the surgery (P < 0.05). Conclusion The modified transanal Soave surgery has small trauma and low complication rate on HD infants in initial radial resection , and the postoperative enteritis and anastomotic orifice stenosis are independent influencing factors for the short-term efficacy.

OBJECTIVETo study whether previously intravenous injection of anisodamine can prevent endotoxemia of heat stroke of rats.

METHODSExperimental animals were randomly divided into two groups, their average artery pressure, heart rate, survival time, survival rate and rectal temperature were measured at an environmental temperature of 38 degrees C-40 degrees C and 50%-60% retative humidity. Blood samples for endotoxins analyses were taken both before and after heat-stress.

RESULTSDuring heat stress, the animals of rectal temperature of the experimental and control groups continuously increased and two hours later, separately to (42.7 +/- 0.6) degree C and (43.1 +/- 0.5) degree C, without statistic difference(P > 0.05), and to (44.6 +/- 0.4) degree C and (44.2 +/- 0.3) degree C prior to death, with statistic difference(P < 0.05). Before the experiment, the contents of endotoxins of portal vein blood were (45.7 +/- 5.2) pg/ml and (42.6 +/- 5.4) pg/ml, and that of systemic blood was (14.8 +/- 4.5) pg/ml and (13.9 +/- 7.2) pg/ml, without statistic difference(P > 0.05). Two hours later, the contents of portal vein blood separately increased to (122.2 +/- 16.7) pg/ml and (49.7 +/- 10.2) pg/ml, obviously higher than that before heat-stress(P < 0.01). And there were clear statistic difference between the two groups(P < 0.01). The changing tendency of the heart rhythm is almost the same in two groups, that is, first rose and then fell. But it is without statistic difference before and two hours later(P > 0.05): before heat-stress, the average artery pressures were (13.3 +/- 0.6) kPa and (13.6 +/- 0.5) kPa, without statistic difference(P > 0.05), and two hours later, were (9.6 +/- 0.5) kPa and (8.6 +/- 0.6) kPa, with obvious statistic difference(P < 0.01). The survival time of the animals were (166.5 +/- 16.9) min and (144.5 +/- 18.2) min with obvious statistic difference(P < 0.01), the survival rate of heat stressed rats in the experimental group were obviously higher than control group(P < 0.01 or P < 0.05).

CONCLUSIONSAnisodamine can prevent endotoxemia in rats suffering heat stroke.

BACKGROUND AND OBJECTIVEFast track surgery (FTS) is a systematical method to accelerate the recovery of surgical patients by reducing the physical and mental trauma stress of them. The research is to investigate the feasibility of FTS application in lung cancer surgery.

METHODSA total of 80 cases of lung cancer patients with single leaf lobotomy resection were randomized into two groups. While the experimental group was treated with the conception of FTS, and the control group was treated with the traditional methods. The incident rate of post-operation pain degrees, telecasts, pleural effusion, the post-operation time stay in hospital time and the total cost during hospitalization in two groups were compared respectively.

RESULTSIn FTS group: the VAS score of post-operation pain at 1 h, 6 h, 12 h, 24 h and 48 h all significantly decreased compared to the traditional therapy group. The incidence rate of telecast was 10.53%. The incidence rate of pleural effusion was 26.31%. The length of stay after operation was (4 +/- 1) d and the total cost was RMB 15 600 +/- 7 600. In the control group, the above values were 77.78%, 33.33%, 22.22%, (9 +/- 1) d, RMB 23 600 +/- 5 400, respectively. The post operation pain (VAS method) of FTS group was remarkablely below the control group. There has significant difference of the incident rate of telecasts, stay time in hospital and the total cast in two groups (P < 0.05). No significant difference was observed in the incident rate ofpleural effusion.

CONCLUSIONThe new methods of FTS can apparently accelerates recovery after lung cancer resection, reduces complications, shorten timestay in hospital and cut down the total cost.

Objective:To evaluate the clinical application value of MR amide proton transfer weighted imaging (APTWI) in predicting the pathological grade of brainstem glioma (BSG).Methods:The data of 41 BSG patients in Beijing Tiantan Hospital, Capital Medical University from August 2019 to June 2020 who underwent both MRI and APTWI 2 weeks before surgery and had pathological grading results were retrospectively analyzed. According to the pathological results, 41 patients were classified into high-grade BSG (20 patients) and low-grade BSG (21 patients). Combined with conventional MR images, the signal intensity (%) of amide proton transfer (APT) in the parenchymal area of the tumor was obtained on APTWI images. χ 2 test or independent sample t-test was used to analyze the differences in gender distribution, age and APT signal intensity between patients with high and low grade BSG. Receiver operating characteristic (ROC) curve was drawn to predict the efficacy of APT signal intensity in the differential diagnosis of high and low grade BSG, and Youden index was calculated to obtain the optimal diagnostic threshold; the predictive ability of APT signal intensity was analyzed in combination with Hosmer-Lemeshow goodness of fit test. Results:There was no significant difference in age [(23±18) years, (20±17) years, t=0.97, P=0.340] and gender distribution (9/11, 9/12 for males/females, χ 2=0.02, P=0.890) between high-grade and low-grade BSG patients. The APT signal intensity of high-grade BSG [(3.9±0.9)%] was significantly higher than that of low-grade BSG [(2.8±0.9)%], and the difference had statistical significance ( t=4.16, P<0.001). The area under the ROC curve of APT signal intensity to distinguish high-grade and low grade BSG was 0.836, and with 2.85% as the optimal diagnostic threshold of APT signal intensity, its sensitivity for the diagnosis of high-grade BSG was 90.0% and specificity was 71.4%. The Hosmer-Lemeshow test showed that APTWI had a good predictive ability for BSG grade (χ 2=13.33, P=0.101). Conclusion:APTWI can be applied in distinguishing high grade BSG from low grade BSG, and has clinical value in predicting glioma grading.

Objective:To explore the diagnostic value of quantitative 99Tc m-hydrazinonicotinamide(HYNIC)-prostate specific membrane antigen (PSMA) SPECT/CT in patients with prostate cancer. Methods:From November 2018 to March 2021, the data of 56 patients ((69.8±8.0) years) with clinically suspected prostate cancer, who had elevated radioactive uptake in prostate on 99Tc m-HYNIC-PSMA SPECT/CT images in Henan Provincial People′s Hospital, were retrospectively analyzed. According to the pathological results, patients were divided into prostate cancer group ( n=45) and non-prostate cancer group ( n=11). The xSPECT-QUANT software was used to quantitatively analyze the high uptake area of the prostate, and SUV max was measured. The independent-sample t test, Mann-Whitney U test, ROC curve and Spearman correlation analysis were used for data analysis. Results:The prostate cancer group had higher SUV max than non-prostate cancer group (10.79±5.96 vs 3.60±1.27; t=7.43, P<0.001). When SUV max≥6.46, the AUC of prostate cancer was 0.887, with the diagnostic sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and accuracy of 73.3%(33/45), 11/11, 100%(33/33), 47.8%(11/23), 78.6%(44/56), respectively. The SUV max of prostate cancer group was positively correlated with Gleason score ( rs=0.632, P<0.001). The SUV max of 29 patients with Gleason score≥8 was higher than that of 16 patients with Gleason score≤7 ( z=-3.89, P<0.001). There was no statistical difference in PSA level between patients with Gleason score≤ 7 and patients with non-prostate cancer ( z=-1.63, P=0.110), but the SUV max was significantly different ( z=-2.22, P=0.026). The SUV max of 23 patients with metastases was higher than that of 22 patients without metastasis (12.99±5.85 vs 8.50±5.28; t=2.69, P=0.010). ROC analysis showed that the AUC was 0.709; with SUV max≥13.02 as the threshold, the sensitivity for diagnosing prostate cancer metastases was 56.5%(13/23), the specificity was 86.4%(19/22), and the accuracy was 71.1%(32/45). Conclusions:The 99Tc m-HYNIC-PSMA SPECT/CT quantitative analysis is feasible in patients with prostate cancer. SUV max of 99Tc m-HYNIC-PSMA can be used in the diagnosis of prostate cancer, assessment of the malignancy and prediction of metastasis.
