Objective:To analyze the clinical characteristics of invasive intervention-related intestinal fistula in patients with acute pancreatitis (AP).Methods:We retrospectively analyzed the clinical data of 177 moderately severe acute pancreatitis (MSAP) or severe acute pancreatitis (SAP) patients who received invasive intervention in Peking Union Medical College Hospital from January 2003 to December 2022. Patients were divided into fistula group and non-fistula group based on the presence or absence of fistula after or during receiving invasive interventions. The age, gender, etiology, systemic inflammatory response syndrome(SIRS), impairment of organ function, revised Atlanta classification, bedside index of severity of acute pancreatitis(BISAP), Balthazar CT classification, extra-pancreatic involvement and secondary infection of local complications, indications, timing and modalities of invasive interventions, length of hospitalization, length of intensive care and outcomes were recorded. The differences on clinical characteristics were compared between the two groups.Results:Intestinal fistulae were found in 21(11.9%) cases during or after invasive intervention, including 8 during or after percutaneous drainage and 13 during or after surgeries. 51 cases received endoscopic drainage or debridement and no intestinal fistula occurred after endoscopic management. Compared to patients without fistula, the median age was younger in the fistula group (36 vs 45 years, P=0.014), and the occurrence of SIRS (95.2% vs 59.6%, P=0.001), extra-pancreatic invasion (100.0% vs 67.3%, P=0.002), and secondary infection (71.4% vs 36.5%, P=0.002) were higher. Patients with fistula had a longer median length of hospitalization (71 vs 40 days, P=0.016) and intensive care (8 vs 0 days, P=0.002). All patients in the fistula group had peri-pancreatic, abdominal and retroperitoneal involvement seen on imaging or intraoperatively. The intestinal fistulae mainly occurred in the colon ( n=13, 61.9%) and the duodenum ( n=6, 28.6%). The confirmed diagnosis of fistulae was based on transfistula imaging ( n=11) or digestive tract imaging ( n=5). Among 13 cases with colonic fistulae, nonsurgical treatment was preferred in 9 cases, and surgeries of fistula repairmen or proximal ostomy were preferred in 4 cases. Among 8 cases with non-colonic fistulae, nonsurgical treatment was preferred in 7 cases, and only 1 case repaired the fistula immediately during the intraoperative detection. Conclusions:Intestinal fistula is an important complication of severe AP, and it is closely associated with invasive interventions. Improved invasive intervention strategies may help prevent intestinal fistula formation; timely and effective management of intestinal fistula may help avoid complications and shorten hospitalization.

BACKGROUND:Intertrochanteric fracture of femur often occurs in the elderly,and there will be a large amount of hidden blood loss after surgery.Reducing hidden blood loss can decrease complications and hospital stay. OBJECTIVE:To evaluate the effect of prolonged use of tranexamic acid on hidden blood loss after proximal femoral nail antirotation implantation in senile intertrochanteric fractures. METHODS:From January 2022 to May 2023,62 elderly admitted patients with intertrochanteric fracture of femur were selected from Zigong Fourth People's Hospital.All of them were treated with proximal femoral nail antirotation implantation after closed reduction on the traction bed.According to the use time of tranexamic acid,they were divided into two groups.In the control group(n=38),1 g tranexamic acid was given intravenically 15-30 minutes before incision,and 1 g was added 3 hours later.Based on the control group,the trial group(n=24)was given 1 g tranexamic acid intravenously once for 12 hours on the first day after surgery.Blood routine examinations were performed before surgery,on the day after surgery,and on the first,third and fifth days after surgery.Hemoglobin and hematocrit were counted.The theoretical total blood loss was calculated by Cross equation,and the incidence of complications in the two groups was recorded. RESULTS AND CONCLUSION:(1)Through statistical analysis,there was no significant difference in the amount of dominant blood loss between the two groups(P>0.05).(2)The number of grams of hemoglobin decreased,total blood loss and hidden blood loss in the trial group during perioperative period were lower than those in the control group,and the differences were statistically significant(P<0.05).(3)The hemoglobin values of the trial group on day 3 after surgery,and the hematocrit values on days 1 and 3 after surgery were higher than those of the control group,with statistical significance(P<0.05).(4)The hemoglobin and platelet count showed a downward trend after surgery,and the hemoglobin value was the lowest value on day 3,and the platelet value was the lowest value on day 1 after surgery,and then began to rise in both groups.(5)There was no significant difference in postoperative complications between the two groups(P>0.05).(6)The results show that prolonging use of tranatemic acid can effectively reduce the hidden blood loss in the treatment of femoral intertrochanteric fracture with proximal anti-rotation intramedullary nail,and does not increase the risk of complications.

Objective To evaluate the predictive ability and influencing factors of individualized drug administration adjuvant decision-making system Java PK? for Desktop(JPKD)for tacrolimus blood concentration in kidney transplant recipients.Methods The monitoring data of tacrolimus blood concentration from 149 recipients early after kidney transplantation were collected.The trough blood concentration of tacrolimus was predicted by JPKD.The absolute weighted deviation and relative prediction deviation between the actual and predicted concentration were calculated.The influencing factors of the absolute weighted deviation were analyzed by univariate and multivariate logistic regression analyses,and the predictive values of these influencing factors on the accuracy of software prediction were assessed by delineating the receiver operating characteristic(ROC)curve.Results Two hundred and sixty-six samples of tacrolimus blood concentration data were collected from 149 patients.The measured blood concentration of tacrolimus was(6.5±3.0)ng/mL(1.1-16.6 ng/mL),and the predicted value calculated by JPKD was(5.6±2.5)ng/mL(1.4-14.4 ng/mL).The absolute weighted deviation of the calculated data was 28.38％,and the relative prediction deviation was-13.55％.Univariate analysis showed that gender,albumin,changes in hematocrit,cytochrome P450(CYP)3A5*3 genotype and C3435T genotype were associated with the inaccurate prediction results.Multivariate logistic regression analysis found that CYP3A5*3 genotype of AA and the changes in hematocrit were the independent risk factors affecting the accuracy of tacrolimus blood concentration predicted by JPKD.ROC curve analysis showed that when the changes in hematocrit exceeded 2.25％,the risk of inaccurate software prediction was increased.Conclusions JPKD possesses certain accuracy in predicting the blood concentration of tacrolimus in kidney transplant recipients,which may improve the qualified rate of tacrolimus blood concentration.Nevertheless,CYP3A5*3 genotype and the changes of hematocrit may affect the accuracy of predictions.

Objective: To investigate the association between maternal parenting styles and quality of life among preschools，to provide a scientific theoretical basis for interventions targeting at prmoting early life health. Methods: From May to July, 2021, a stratified cluster sampling method was used to enroll 4 233 child mother dyads from 14 preschools in Chengdu. An online questionnaire survey was administered to collect socio demographic information, maternal parenting styles, and children s quality of life. Results: The overall score of quality of life was (80.17±9.81) among preschool children in Chengdu. In the multivariate linear regression models, maternal emotional warmth were significantly associated with higher scores in emotional functioning, social functioning, school functioning, psychosocial health summary score, and total scores ( β coefficients in the high level group were 2.63 , 4.95 , 12.05, 6.54,4.88, P <0.05). In contrast, both maternal rejection and overprotection were significantly associated with lower scores in physical functioning, emotional functioning, social functioning, school functioning, psychosocial health summary score, and the total scores of children s quality of life (for rejection: β coefficients in the high level group were -9.39, -10.82, -7.12 , -6.04 , -8.00, and -8.35 , respectively; for overprotection: β coefficients in the high level group were -6.71, -5.85, -3.08 , -2.39 , -3.77, and - 4.51 , respectively， P <0.05). The associations between high level of maternal rejection and children s emotional functioning showed significant gender differences( β =-3.23, P <0.05). Conclusion Maternal parenting style has a significant impact on children s quality of life. Interventions targeting at maternal parenting styles may be beneficial to improve the quality of life in preschool children.

The latter 3 patients underwent second operation under CPB, after then, 1 patient had mild AR and 2 patients had moderate AR. The follow-up time was 13.1±4.6 months. At the latest follow-up, 12 patients had mild AR and 5 patients had moderate AR, and no patient had reoperation. Conclusion    A combined technical system for BAV repair can be used effectively and safely with an acceptable short and middle-term result.

OBJECTIVE To observe the efficacy and safety of albumin-bound paclitaxel in the treatment of advanced non- small cell lung cancer （NSCLC）. METHODS Clinical data of patients with advanced NSCLC treated in our hospital from January 2018 to December 2021 were selected. According to their chemotherapy regimen，they were divided into albumin-bound paclitaxel group and paclitaxel group， with 100 patients in each group. Both groups received chemotherapy regimen containing Paclitaxel for injection （albumin-bound） or Paclitaxel injection for at least 2 cycles （every 21 days as a cycle）. The progression-free survival （PFS） and efficacy of the two groups were compared，and the occurrence of toxic and side effects were recorded. RESULTS The patients in albumin-bound paclitaxel group completed 430 cycles of chemotherapy， with an average of 4.3 cycles； patients in paclitaxel group completed 476 cycles of chemotherapy， with an average of 4.8 cycles. The median PFS （4.0 months） and the response rate （13.00%） of albumin-bound paclitaxel group were not significantly different from those of paclitaxel group （4.0 months，9.00%） （P＞0.05）. The disease control rate （99.00%） was significantly higher than that in paclitaxel group （89.00%）， and the incidences of leukopenia， neutropenia， thrombocytopenia，anemia， sensory neuropathy， fatigue，nausea and vomiting，joint myalgia in albumin-bound paclitaxel group were significantly lower than those in paclitaxel group （P＜0.05）. CONCLUSIONS Albumin-bound paclitaxel is effective in the treatment of advanced NSCLC， and it can better control the progression of the disease and is safer than ordinary paclitaxel.
