Objective:To investigate the clinical efficiency of lumbar hernia repair based on path planning.Methods:The retrospective and descriptive study was conducted. The clinical data of 35 patients with lumbar hernia who were admitted to The First Affiliated Hospital of University of Science and Technology of China from November 2016 to March 2024 were collected. There were 14 males and 21 females, aged (61±8)years. According to preoperative computerized tomography examination of the hernia defect diameter, patients with a defect diameter <4 cm underwent enhan-ced field laparoscopic total extraperitoneal repair (eTEP), patients with a defect diameter of 4-8 cm underwent laparoscopic partial extraperitoneal repair (TAPE), and patients with a defect diameter >8 cm underwent open preperitoneal mesh repair (Sublay). Measurement data with normal distribu-tion were represented as Mean± SD, and comparison of three groups were conducted using the one-way ANOVA or Kruskal Wallis test, and Bonferroni correction was used for pariwise comparison. Measurement data with skewed distribution were represented as M(range). Count data were descri-bed as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test or Fisher exact probability. Results:(1) Operation conditions. Of 35 patients, there were 15 cases undergoing eTEP, of 7 males and 8 females and 12 cases of left hernia and 3 cases of right hernia, with operation time of (92±44)minutes and the duration of postoperative hospital stay of (5.6±2.8)days. There were 17 cases undergoing TAPE, of 5 males and 12 females and 9 cases of left hernia, 7 cases of right hernia and 1 case of bilateral hernia, with operation time of (114±56)minutes and the duration of postoperative hospital stay of (6.4±3.0) days. There were 3 cases undergoing Sublay, of 2 males and 1 female and 1 case of left hernia and 2 cases of right hernia, with operation time of (150±55)minutes and the duration of postoperative hospital stay of (12.3±7.8)days. There were significant differences in the duration of postoperative hospital stay among the three groups ( F=4.83, P<0.05). (2) Follow-up. All 35 patients were followed up for 40.5(range, 3.0-91.0)days. None of patient underwent postoperative complications such as serous swelling, incision infection, intestinal fistula, intestinal obstruction, or puncture hematoma, and no recurrence of lumbar hernia occurred. One patient who underwent TAPE had postoperative abdominal distension, and was cured by symptomatic treatment. Cases with acute pain within postoperative 3 months were 0, 5, 2 in patients undergoing eTEP, TAPE, Sublay, respectively, showing significant differences among them ( χ2=8.69, P<0.05). Results of pariwise comparison showed that there was a significant difference in acute pain within postoperative 3 months between patients undergoing eTEP and Sublay ( P<0.05), and there was a significant difference in acute pain within postoperative 3 months between patients undergoing eTEP and TAPE ( P<0.05); Cases with chronic pain after postoperative 3 months were 0, 1, 1 in patients undergoing eTEP, TAPE, Sublay, respectively, showing no significant difference among them ( χ2=4.00, P>0.05). Conclusion:It is safe and feasible to formulate the surgical method according to the defect diameter of lumbar hernia.

Background and Aims:Parastomal hernia is a common complication after colostomy,with a high incidence rate.Laparoscopic Sugarbaker repair is currently the mainstream surgical approach for treating parastomal hernia.However,compared to other abdominal wall hernia repair techniques,the recurrence rate of parastomal hernia after laparoscopic Sugarbaker repair remains relatively high.Furthermore,the recurrence rate after surgery for recurrent parastomal hernias is significantly higher than that after the initial surgery,with inadequate lateral mesh coverage being one of the major contributing factors.This study was performed to analyze the efficacy of two-point mark-guided laparoscopic Sugarbaker repair in patients with terminal colostomy parastomal hernia,so as to provide evidence-based references for clinical practice. Methods:The clinical data of 120 patients with terminal colostomy parastomal hernia,who underwent laparoscopic Sugarbaker repair guided by the two-point mark of mesh at the Department of Hernia and Obesity Surgery,the First Affiliated Hospital of the University of Science and Technology of China,from January 2015 to December 2023,were retrospectively collected.The parastomal hernias were classified according to the European Hernia Society classification.Postoperative symptomatic and radiological recurrence rates were analyzed,as well as the incidence of complications such as bowel obstruction,stoma infection,and intestinal fistula in recurrent and non-recurrent patients. Results:Of the 120 patients,2(1.7％)were lost to follow-up.The mean follow-up duration was 48(6-96)months.The postoperative symptomatic recurrence rate was 5.1％(6/118),and the radiological recurrence rate was 6.8％(8/118).There were no statistically significant differences between recurrent(n=8)and non-recurrent patients(n=110)in terms of sex,age,body mass index(BMI),or hernia defect size(all P＞0.05),but the operative time in recurrent patients was longer than that in non-recurrent patients(P＜0.05).The overall postoperative complication rate was 8.5％(10/118),including stoma skin-mucosa separation(3 cases),stoma infection(2 cases),delayed bowel obstruction(2 cases),early bowel obstruction(1 case),hernia sac effusion(1 case),and delayed fistula formation in the hernia sac cavity(1 case).According to the Clavien-Dindo classification,there were 6 cases of grade Ⅱ,3 cases of gradeⅢa,and 1 case of grade Ⅳ complications.There were no statistically significant differences between patients with and without complications regarding sex,BMI,hernia defect size,operative time,and comorbidities(all P＞0.05);however,patients with complications were older than those without(P＜0.05). Conclusion:The application of laparoscopic Sugarbaker repair under the guidance of two-point mesh identification can effectively reduce the recurrence rate of parastomal hernia and It has high clinical applicability.

ObjectiveAgrobacterium tumefaciens-mediated transformation （ATMT） of Clonostachys rosea， an endophytic fungus of Glycyrrhiza uralensis seeds， was established and optimized， and orthogonal test was designed to optimize the colonization conditions of C. rosea for G. uralensis seeds， so as to lay foundation for the development of biofertilizer and the breeding of high-quality G. uralensis. MethodThe conditions of ATMT were optimized from three aspects， including the concentration of acetosyringone， co-culture time and the concentration of conidia of recipient fungi. Then， high-quality transformants were selected. Orthogonal test was used to optimize the colonization conditions by taking co-culture temperature， co-culture time and spore concentration as factors and colonization rate as index. ResultWhen spore concentration was 1×10⁷ cfu·mL^-1， acetosyringone concentration was 150 μmol·L^-1 and the co-culture time was 60 h， the transformation efficiency of C. rosea was the highest， which was 135 transformants per 1×10⁷ recipient fungal spores. The accuracy and stability of the transformations were tested by cloning the marker gene green fluorescent protein （GFP） and β-glucuronidase （GUS） staining. When co-culture temperature was 25 ℃， co-culture time was 36 h and the spore concentration was 1×10⁶ cfu·mL^-1， the colonizing rate for C. rosea back dyeing into G. uralensis seeds by seed soaking method was the highest， which was 71.11%. ConclusionThis study successfully establishes stable and efficient technical systems not only of ATMT in C. rosea， but also of colonization of the transformants into G. uralensis seeds， which can lay a foundation for the development of biofertilizer of G. uralensis.

OBJECTIVE: To explore the molecular basis for two brothers affected with globozoospermia. METHODS: Whole exome sequencing was carried out for both patients. Candidate variant was verified by Sanger sequencing and quantitative real-time PCR (qRT-PCR). RESULTS: Whole exome sequencing, Sanger sequencing and qRT-PCR verification revealed a heterozygous c.384dup (p.Glu129*) variant in the DPY19L2 gene in the two brothers and their mother. A large heterozygous deletion, spanning approximately 164.5 kb and encompassing the entire DPY19L2 gene, was detected on chromosome 12 of the two patients and their father. CONCLUSION The c.384dup (p.Glu129*) variant and deletion of the DPY19L2 gene probably underlie the pathogenesis of globozoospermia in the two patients, which was in keeping with the autosomal recessive inheritance of disease in this pedigree.

Objective To study the renal prognosis with the type and proportion of crescentic in adult Henoch Schonlein purpura nephritis (HSPN).Methods A total of 275 HSPN cases diagnosed in the First Affiliated Hospital of Zhejiang University were retrospectively analyzed.According to the pathological results,they were divided into four groups:99 patients in none crescent group (NC),35 patients in segmental crescents group (SC),122 patients with circumferential crescent ＜25％ (C1),and 19 patients with circumferential crescent≥25％ (C2).Renal prognostic events were defined as estimated glomerular filtration rate (eGFR) decreased by 30％ over baseline within 2 years,doubling of serum creatinine or end-stage renal disease during follow-up.Kaplan-Meier survival analysis was used to compare the renal survival rate of each group.Univariate and multivariate Cox regression model was used to recognize the risk factor of poor renal outcome.Results There was no significant difference in age,extra renal organ performance and mean arterial pressure among groups.Among NC group,SC group,C1 group and C2 group,difference in serum creatinine (P=0.001),eGFR (P=0.003) and proteinuria levels (P ＜ 0.001) were statistically significant.There was no significant difference in the ratio of global sclerosis,mesangial hypercellularity and interstitial inflammation/fibrosis among the groups.The patients were followed up for 86(58,116) months.The renal survival rates of NC group,SC group,C1 group and C2 group were 96％,100％,83.6％ and 68.4％ respectively.Kaplan-meier survival analysis showed significant differences (Log Rank=23.24,P＜ 0.001).Cox multivariate regression analysis indicated that presence of circumferential crescent (HR=3.59,95％CI 1.34-9.62,P=0.008) and low eGFR (HR=0.979,95％ CI 0.968-0.989,P ＜ 0.001) were independent prognostic factors.Conclusion The presence of circumferential crescent and low eGFR level are independent risk factors for poor renal prognosis in HSPN patients.

Objective: To investigate the assessment and treatment strategy of patients with renal cell carcinoma. Methods: The clinical data of 43 patients with renal cell carcinoma and bone metastases admitted to the First Affiliated Hospital of Nanjing Medical University from January 2006 to December 2018 were retrospectively analyzed. The follow-up time was 6 years, with an average age of 55.4 years (21-87 years). There were 29 males, 14 females, 22 cases of limb bone metastasis, 12 cases of spinal metastasis, 9 cases of multiple bone metastasis, 21 cases of Fuhrman grade 1 and 2, 19 cases of T₁, and 20 cases of N₀. All patients were confirmed by postoperative pathological examination or imaging data suggesting that bone metastasis are from renal cell carcinoma. Forty-three patients underwent primary renal surgery, and molecular targeted therapy was used after the operation. The treatment process was smooth, no obvious discomfort, and postoperative pathology showed clear cell carcinoma.22 patients with limb bones metastasis and 12 patients with spinal metastasis included in the study all met the indications for secondary surgery after the disease assessment. After communicating with the patient, 13 patients with limbs metastasis and 6 patients with spinal metastasis received local treatment, including complete resection of the extremities and spinal fixation, the remaining 15 patients and 9 patients with multiple bone metastasis were treated conservatively. There were 19 patients in the local treatment group, 13 patients with limbs bone metastasis, 6 patients with spinal bone metastasis, the average age was 54.9 years, the average diameter of the primary tumor was 4.7 cm. There were 24 patients in the conservative treatment group, 9 patients with limbs metastasis, 6 patients with spinal metastases and 9 cases with multiple bone metastasis, with an average age of 56 years and a primary tumor diameter of 5.6 cm. Limb metastatic lesions were evaluated according to the patient's general condition, bone pain, fracture risk, and bone metastasis. Spinal lesions were evaluated according to Tokuhashi score, Harrington score, Tomita score, vertebral stability assessment, and molecular targeted therapy. Aminokinase inhibitors, conservative treatment with local radiotherapy and bisphosphonate treatment. Results: During the follow-up period, the 1-year overall survival rate of the local treatment group was 100.0%, the 2-year overall survival rate was 89.4%, and the 5-year overall survival rate was 73.7%. The 1-year overall survival rate of the conservative treatment group was 87.5%, and the 2-year overall survival rate was 62.5%. The 5-year overall survival rate was 16.7%. The 2-year and 5-year survival rates of the local treatment group were statistically different (P=0.044, P=0.000) compared with the conservative treatment group. For patients with limb bone metastasis, the 5-year survival rate was significantly higher in patients receiving topical treatment than in the conservative treatment group (P=0.011). For spinal metastasis, spinal pain in the local treatment group was alleviated to varying degrees. No spinal instability and spasticity were observed after follow-up. In the spine patients who received conservative treatment, 3 patients developed paraplegia, which was statistically different from local treatment (P=0.046). Another 9 patients with multiple bone metastases did not undergo local surgery, and all died after multiple organ failure. Conclusions At the same time of molecular targeted therapy, according to the evaluation results, selective treatment of bone metastases with secondary surgical indications, including complete resection of the extremities and spinal fixation, can significantly improve the survival and quality of life of those patients.

Objective To summarize the experiences of diagnosing and treating acute pancreatitis (AP) after kidney transplantation .Methods From September 2007 to December 2017 , clinical data were retrospectively analyzed for 12 AP patients after kidney transplantation .Results They were diagnosed as AP within 72 h after an onset of abdominal pain .Among 4 recurrent cases within 1 week post-transplantation ,the curative interventions included non-operative therapy (n=2) and peripancreatic puncture & drainage (n=2) .AP occurred at 1 year post-transplantation (n=8) . Three cases were cured non-surgically while another 5 cases underwent surgery . The procedures included laparoscopic cholecystectomy ( n = 1 ) , endoscopic retrograde cholangiopancreatography (ERCP) for cholelithiasis (n=1) and peripancreatic puncture & drainage (n= 2) .One patient died after surgical debridement for adjacent pancreatic tissue .Conclusions After kidney transplantation , the occurrence of AP may be associated with immunosuppressants interfering with triglyceride metabolism and pancreatic microcirculation .For those with cholelithiasis-related pancreatitis ,surgical removal of precipitating factor is required .Mini-invasive puncture and drainage are preferred for severe non-gallstone pancreatitis while surgery is performed whenever necessary .
