Objective:To investigate the preventive effect of postoperative pancreatic fistula by pedicled omentum wrapping pancreaticojejunostomy in pancreaticoduodenectomy.Methods:The clinical data of 78 patients who underwent pancreaticoduodenectomy in Songjiang Hospital Affiliated to Shanghai Jiao Tong University from September 2017 to August 2020 were retrospectively analyzed. Patients were divided into the modified pancreaticojejunostomy group (conventional approach group, n=43) and the pedicled omentum wrapping pancreaticojejunostomy group (omentum wrapping group, n=35) according to the surgical mode. Postoperative pancreatic fistula, postoperative abdominal bleeding, delayed gastric emptying and postoperative hospital stay were compared between the two groups. Results:Compared with the conventional approach group, the postoperative pancreatic fistula rate in omentum wrapping group was significantly reduced (2.9% vs 18.6%), and the difference was statistically different ( P=0.030); postoperative abdominal bleeding rate(0 vs 4.7%)and the delayed gastric emptying rate were significantly reduced (8.6% vs 25.6%), but both of them were not statistically different ( all P value>0.05); the length of postoperative hospital stay was significantly reduced [(11.3±2.9) days vs (12.8±3.5)days], and the difference was statistically different ( P=0.045). Conclusions:The pedicled omentum wrapping pancreaticojejunostomy was simple and convenient, which can significantly reduce the rate of postoperative pancreatic fistula. It can shorten the time of the length of hospital stay after surgery.

[摘 要] 目的：探讨肝内胆管癌（intrahepatic cholangiocarcinoma，ICCA）围手术期外周血中性粒细胞与淋巴细胞比率（neutrophil-to-lymphocyte ratio，NLR）和血小板与淋巴细胞比率（platelet-to-lymphocyte ratio，PLR）对患者预后的预测价值。方法：收集2015年1月至2018年1月在上海市松江区中心医院接受肝切除术治疗的ICCA患者97例作为ICCA组，选择同期在本院做健康体检的志愿者100例作为正常对照组。检测两组受试者术前1 d、术后3 d和7 d外周血的NLR、PLR，采用单因素、多因素分析ICCA患者术后随访期死亡的危险因素，采用Kaplan-Meier生存曲线分析术后3 d的NLR和PLR对ICCA患者术后生存时间的影响，采用受试者工作特征曲线（receiver operating characteristic curve，ROC）分析术后3 d的NLR和PLR水平对患者术后随访期死亡的预测价值。结果：ICCA组患者术前1 d、术后3和7 d外周血的NLR、PLR均高于正常对照组（均P<0.05），术前1 d和7 d外周血NLR、PLR差异无统计学意义（P>0.05），术后3 d外周血NLR、PLR水平最高（P<0.05）。多发肿瘤、合并淋巴结转移、TNM分期Ⅲ~Ⅳ、CA199水平增高、术后3 d的NLR和PLR较高分别是ICCA患者随访期死亡的独立危险因素（均P<0.05）。ROC曲线显示，术后3 d的NLR和PLR高低对ICCA患者术后生存时间具有预测价值。Kaplan-Meier生存曲线显示，低NLR[（50.32±3.69） vs （30.12±2.36）个月]和低PLR[（53.6±3.75） vs （37.6±2.96）个月]患者生存时间均长于高NLR和PLR的ICCA患者（均P<0.05）。结论：ICCA术后3 d的NLR和PLR异常增高是患者肝切除术后死亡的独立危险因素，其对患者生存时间具有早期预测价值。

Objective To investigate the correlation between the severity of alcoholic fatty liver disease and the amount of fat in the abdominal cavity and the serum inflammatory factor IL-18 and IL-8. Methods From October 2016 to October 2017,one hundred and twenty patients with AFLD in the First Hospital of Hebei Medical University were divided into light,medium,heavy groups according to the severity of fatty lesions by color Doppler Ultrasound. There were 40 mild patients,50 moderate patients and 30 severe patients. Forty healthy subjects were selected as controls. All the participants underwent CT scanning. The intra-abdominal fat area (VAT),abdominal subcutaneous fat area (SAT) and total abdominal fat area (TA) were measured. The liver function was measured by biochemical analyzer and enzyme-linked immunoassay (ELISA). (ELSIA) IL-18 was detected and IL-8 was detected by radioimmunoassay. Results The VAT of the healthy control group and the mild,medium and severe AFLD group were (70. 28±10. 19),(114. 38 ± 9. 97),(146. 73±10. 19),(163. 38±12. 69) cm2. The TA of the healthy control group and the mild, medium and severe AFLD group were ( 256. 72± 34. 56),( 332. 19 ± 33. 28),( 387. 49± 32. 28),( 478. 19 ±31. 02) cm2. The SAT of the healthy control group and the light,medium and severe AFLD group were (156. 23±28. 19),(203. 43±27. 12),(246. 19±26. 89),(271. 19 ±27. 94) cm2,respectively. Aspartate aminotransferase (AST) of the healthy control group and the mild,medium and severe AFLD group were (18. 50±1. 12),(23. 50±1. 21),(25. 50±1. 24),(29. 50± 1. 43) U/L. Alanine aminotransferase (ALT) of the healthy control group and the light, medium and severe AFLD group were ( 18. 50 ± 2. 14), ( 26. 50 ±2. 22),(35. 50±2. 34),(38. 50±2. 11) U/L. γ-glutamyltransferaseof the healthy control group and the light,medium and severe AFLD group were ( 16. 50 ± 2. 11), ( 32. 50 ± 2. 23), ( 47. 50 ± 2. 31), ( 48. 00 ±2. 43) U/L,respectively. Compared with the healthy control group,VAT,TA,SAT,AST,ALT andγ-GT in the light,medium and heavy AFLD group showed statistically significant differences ( P＜0. 05) . Compared with the mild AFLD group, VAT, TA, SAT, AST, ALT and γ-GT in the medium and heavy AFLD group showed statistically significant differences ( P＜0. 05) . Compared with the moderate AFLD group,the VAT, TA,SAT, AST, ALT, and γ-GT of the severe AFLD group showed statistically significant differences ( P＜0. 05). The data of the three AFLD groups showed that the concentration of all indicators were increasing as the severity of fat deepened. IL-18 of the healthy control group and the light,medium and severe AFLD group were (45. 67±4. 51),(52. 18±5. 09),(59. 87±4. 98),(64. 18±5. 12) ng/L; IL-8 of the healthy control group and the light, medium and severe AFLD group were ( 78. 92 ± 5. 07), ( 115. 62 ± 4. 89), ( 223. 76 ± 6. 78),(286. 42±7. 02) g/L. Compared with every group,IL-18 and IL-8 of light,medium and severe AFLD group showed statistically significant differences (F＝1035. 67,2. 93×105,P＜0. 001); compared with mild AFLD group,IL-18 and IL-8 of medium and heavy group showed statistically significant differences;compared with moderate AFLD group,IL-18 and IL-8 of severe group AFLD showed statistically significant differences ( P＜0. 001) . The levels of inflammatory factors IL-18 and IL-8 increased with the severity of steatosis. The severity of AFLD was significantly positively correlated with VAT,TA,SAT,IL-18 and IL-8 ( r 0. 415(P＜0. 001), 0. 435 ( P＜0. 001), 0. 512 ( P＜0. 001), 0. 274 ( P＜0. 001 ), 0. 689 ( P ＜0. 001). Conclusion Fat control is an important measure to prevent AFLD. IL-18 and IL-8 can reflect the severity of liver injury in AFLD and have important significance in judging prognosis.

Wilms′ tumor is a common malignant tumor in children.Most patients have a good prognosis, but its pathogenesis is not yet clear.In recent years, some non-coding RNAs have been found to have a close relationship with the development of this tumor.Some non-coding RNAs may serve as biomarkers for the diagnosis, predictors indicators, or targets for gene therapy.This paper studied the relationship between some non-coding RNAs associated with nephroblastoma is now available.

Objective: To explore the safety and feasibility of transumbilical single channel laparoscopic cryptorchidopexy with conventional instruments in treatment of cryptorchidism in children. Methods: Thirty-five children with cryptorchidism were treated by transumbilical single channel laparoscopic cryptorchidopexy with conventional instruments from November 2017 to March 2018 at Department of Pediatric Surgery, the First Affiliated Hospital of Guangxi Medical University.Clinical data were recorded including the general information, operation time, intraoperative blood loss, postoperative testicular position and postoperative complications, etc. Results: All 35 patients completed the cryptorchidopexy in one operation.Among those 35 patients, 28 patients had unilateral lesions and 7 patients had bilateral lesions, with a total of 42 sides.Twenty-six patients were of groin type(33 sides), 9 patients abdominal type(9 sides). The average operation time was (40.4±8.2) min for unilateral lesion, and (62.5±15.3) min for bilateral lesions; the average intraoperative blood loss was (3.0±1.8) mL; and the average postoperative hospital stay was (6.4±2.1) h. Testis of 32 patients (40 sides) were fixed in the middle and bottoms of the scrotum, and testis of 2 patients (2 sides) were fixed on the top of the scrotum.One case had poor healing of naval incision, which was recovered in 1 week after dressing change.There were no postoperative complications such as scrotum hematoma, infection of incision, testicular epididymitis, testicular necrosis, testicular retraction or testicular atrophy, etc.No obvious visible scar was found in the abdomen review 2 weeks postoperatively, with the incidence of complications was 2.9%(1/35 cases). Conclusions Transumbilical single channel laparoscopic cryptorchidopexy with conventional instruments in treatment of cryptorchidism is characterized by small trauma, quick recovery, low complication rate and visible scar free result, which is worthy of clinical promotion, but the operation is relatively complex and the correct procedures are required.

BACKGROUND:Umbilical cord mesenchymal stem cells are plentifully and conveniently obtained with a high proliferative ability, and have opened up a new way to treat patients with liver failure as they can differentiate into hepatocyte-like cells.OBJECTIVE:To observe the safety and efficacy in the treatment of chronic liver failure by transplanting umbilical cord mesenchymal stem cells.METHODS:Using parallel contrast method, 50 patients with chronic liver failure were divided into two groups, namely a stem cell group and a control group, containing 25 patients in each group. For the first group, transplantation of umbilical cord mesenchymal stem cells, (1.4-2.3)×106/kg, 100 mL, was given on the basis of medical comprehensive treatment,while for the second group only simple medical comprehensive treatment was given. The injection was done every 15 days, totally three times. Liver functions, prothrombin activity, Model for End-Stage Liver Disease (MELD) score, clinical symptoms, survival and side effects of the patients were observed before and 2, 4, 12 and 24 weeks after the treatment.RESULTS AND CONCLUSION:Compared with the control group, the albumin level and prothrombin activity were significantly increased in the stem cell group 12 and 24 weeks after treatment (P < 0.05), while the MELD score was significantly decreased in the stem cell group at 4, 12 and 24 weeks after treatment (P < 0.05). There was no significant difference in alanine aminotransferase and total bilirubin levels between the two groups (P > 0.05). Four weeks after treatment, clinical symptoms of the stem cell group improved significantly in comparison with the control group (P < 0.05).During the 24-week follow-up, the survival rate in the stem cell group was significantly higher than that in the control group (P < 0.05). Additionally, there were no adverse reactions and liver cancer associated with the stem cell therapy.Results show that it is safe and effective to treat patients with chronic liver failure through the transplantation of umbilical cord mesenchymal stem cells, and the cell transplantation can significantly improve patients' survival rate.

Objective To evaluate the curative effectiveness and safety of human chorionic gonadotropin(HCG) treatment on children with microphallic hypospadias.Methods A total of 48 consecutive children with microphalic hypospadias were enrolled in the study,and the children were randomized into the experiment group(HCG treatment) and the control group with the research randomizer.The patients in experiment group were treated with HCG prior to surgery,and the control group did not received any hormone therapy preoperatively.All children in the experiment group and the control group underwent hypospadias repair by using transverse preputial island flap (Duckett technique) urethroplasty.Penile length,diameter of glans penis,bone age,serum testosterone level,and secondary effects were recorded before and after therapy in the experiment group.Postoperative complications were assessed with respect to fistulas,urethral strictures,diverticula,meatal stenosis,and glanular dehiscence in both groups.Results (1)Mean penile length and diameter of the experiment group increased significantly by (1.08±0.47) cm (t=-5.196,P<0.05) and (0.31±0.06) cm and there was a significant difference between before and after treatment (t=-5.080,P<0.05).(2)Urethrocutaneous fistulas were observed in 8 patients in the control group compared to 2 patients in the experiment group with a statistically significant difference (χ2=4.547,P<0.05).There was a significant difference between the overall reoperation rates of control group (9 patients) and the experiment group (3 patients,χ2=4.000,P<0.05).The penile tissue of the patients in the experiment group was soft and able to be easily separated and released during the operation and the flap had more blood supply.Conclusions Pretreatment with HCG therapy prior to hypospadias repair is beneficial to children with microphallic hypospadias.Significant penile growth was seen in the children treated with HCG and there was no obvious side effect.Moreover,pretreatment with HCG is beneficial to decrease the complications and reoperation rates of hypospadias repair which proves to be effective and safe.
