Objective To investigate the clinical features of pedistric Littre hernia.Methods Clinical data of 11 cases of Littre hermia admitted from January 2002 to December 2010 was studied retrospectively.Results The diagnosis of Littre hernia was all established by laparotomy.All of the 11 cases were boys,the median age was 1.2 years (22 days to 3 years and 7 months).The main clinical features were:painful,irregular and nonresetable mass in the groin area (11/11),vomiting in 6 cases (6/11 ),fever (＞38.5 ℃ ) in 4 cases (4/11 );X-ray showed intestinal obstruction in 9 cases (9/11 ),Ultrasound found mixed mass in the groin area in 11 cases ( 11/11 ),pouch-like structure were found in 6 cases (6/11).Eight cases (8/11) presented with elevated WBC ( ＞ 10000).Palpable lobulated structure were fell in 5 cases (5/11).All cases of Littre hernia were successfully operated on,Meckel diverticulum perforation was found in 2 cases ( 2/11 ),Meckel diverticulum adhered to the hernia sac in 8 eases (8/11).All patients were cured by surgery,and postoperative follow-up (10ms-8y) found no recurrence.Conclusions Pediatric Littre hernia is rare,preoperative diagnosis is difficult.Avoiding preoperative violent reduction and intraoperative injuring Meekel's diverticulum or the small bowel helps improve the cure rate of Littre hernia in children.

Objective To study the clinical value of tamsulosin in prevention of urinary retention after radical hysterectomy.Methods Sixty-six patients after radical hysterectomy were enrolled in this study, and divided into two groups in random.Thirty-three cases in the treatment group were treated with tamsulosin 0.2 mg once every night,3 days before the catheter was drawn.While 33 cases in the control group only with placebo.Catheter keeping days, residual urine volume at first extraction,the rate of urinary retention and urinary tract infection,hospitalization time and drug adverse reaction were compared in two groups.Results Catheter keeping days and hospitalization time were shorter in the treatment group than those in the control group(P< 0.05).The residual urine volume at first extraction was(38.2 ± 5.6) ml in the treatment group and (168.5 ± 11.8) ml in the control group,there was significant difference between two groups (P< 0.05).The rate of urinary retention was 18.2%(6/33) in the treatment group and 36.4%(12/33) in the control group,there was significant difference between two groups (P <0.05).There was no adverse reaction resulted from tamsulosin in the treatment group.Conclusion Tamsulosin is an effective drug which could prevent and treat the urinary retention after radical hysterectomy.

Objective To evaluate the efifcacy and safety of hemostatics of injected gelatin matrix (HIGM) under the guidance of contrast-enhanced ultrasound (CEUS) for treating splenic trauma in canine model. Methods A total of 24 commercial hybrid dogs underwent celiotomy with creation of uniformly blunt splenic trauma lesion of 4.0 cm×4.0 cm×2.5 cm (length, width and depth, respectively) by hemostatic clamp. Subjects were prospectively randomized into two groups. The treatment group was treated with HIGM under the guidance of CEUS and the positive control group received thrombin solution. Conventional ultrasound and CEUS were performed to record the ascites and the splenic lesion areas at 1st, 3rd, 7th, 14th and 21st day. The ifne needle biopsy and splenectomy were performed for histopathologic examination. The weight, free intraperitoneal lfuid and injury site were compared with t test between HIGM and postive group. Results All animals in two groups survived. All dogs stopped hemorrhage after injection of HIGM under CEUS guidance. The area of injury site was (12.91±0.89) cm2, (4.45±0.75) cm2 and (1.38±0.23) cm2 at 1st, 3rd and 7th day and splenic lesions were not found at 14th and 21st day in all dogs (n=12) of HIGM group. The splenic lesion was (16.74±0.91) cm2, (11.26±0.99) cm2, (8.02±0.82) cm2 and (1.58±0.36) cm2 in the postive group at 1st, 3rd, 7th and 14th day and splenic lesions were not found at 21st day in all dogs (n=12). At 7th and 14th day post-injection, lesion areas were statistically significant between two groups (t=27.162, P=0.008;t=15.129, P=0.001). Free intraperitoneal lfuid was (0.91±0.05) cm at 1st day detected by conventional ultrasound and free intraperitoneal fluid was not found at 3rd, 7th, 14th and 21st day in all dogs (n=12) of HIGM group. The free intraperitoneal fluid in thepositive group was (1.96±0.17) cm, (1.30±0.11) cm and (0.81±0.12) cm at 1st, 3rd and 7th day and free intraperitoneal lfuid was not found at 14th and 21st day in all dogs (n=12). At 1st, 3rd and 7th day post-injection, free intraperatitoneal lfuid was statistically significant between two groups (t=20.934, P=0.003; t=41.310, P=0.000; t=22.520, P=0.000). Histopathological examination showed that there was no foreign body and foreign body granuloma and the structure of red pulp was recovered at 7th, 14th and 21st day. Gross anatomy showed that the splenic injury site was recovered completely without complications. Conclusion This study explored the value of HIGM for splenic trauma and provided a preliminary experimental evidence for clinical treatment.

OBJECTIVETo examine serum concentration of interleukin-18 (IL-18) and IL-18 mRNA expression in peripheral blood mononuclear cells (PBMCs) in children with primary nephrotic syndrome (PNS) and explore the possible role of IL-18 in steroid-resistant nephrotic syndrome (SRNS).

METHODSSixty-six children with newly diagnosed PNS, including 39 cases of steroid sensitive nephrotic syndrome (SSNS) and 27 cases of SRNS, were enrolled. Forty healthy children were used as a normal control group. Blood samples were collected before and 8 weeks after glucocorticoid treatment. Serum concentration of IL-18 was measured using ELISA. IL-18 mRNA expression in PBMCs was detected by the RT-PCR method. The amount of 24-hr urine protein was measured by the biuret method. Serum contents of total cholesterol (T-Ch), triglyceride (TG), low density lipoprotein (LDL), total protein (TP), and albumin (Alb) were measured by the automatic biochemistry analyzer.

RESULTSSerum concentration of IL-18 and IL-18 mRNA expression in PBMCs in the SSNS and the SRNS groups were significantly higher than those in the normal control group before treatment (P< 0.05). The SRNS group had increased serum protein concentration of IL-18 and IL-18 mRNA expression in PBMCs compared with the SSNS group before treatment (P< 0.05). Serum LDL content in the SRNS group was also significantly higher than that in the SSNS group before treatment (P< 0.05). After treatment, serum concentration of IL-18 and IL-18 mRNA expression in PBMCs in the SRNS group were significantly higher than those in the SSNS and the normal control groups (P< 0.05). Serum concentration of IL-18 and IL-18 mRNA expression in PBMCs in the SSNS group were significantly reduced after treatment, but the alterations of IL-18 were not observed in the SRNS group after treatment.

CONCLUSIONSSRNS was associated with increased serum IL-18 concentration and IL-18 mRNA expression in PBMCs. Over-production of IL-18 may play a role in the development of SRNS.

Objective:To investigate the clinical safety and efficacy of robot-assisted laparoscopic ventral onlay lingual mucosal graft ureteroplasty for ureteral stricture.Methods:The clinical data of 6 patients with ureteral stricture admitted to the Guizhou Provincial People's Hospital from December 2020 to August 2022 were retrospectively analyzed. There were 3 males and 3 females, with an average age of (40.2±11.5) years old. The status of ureteral stricture and hydronephrosis was measured by ultrasonography, CT urography and ureteral retrograde angiography. There were 2 cases of left ureteral stricture and 4 cases of right ureteral stricture, including 4 cases of upper segment stricture and 2 cases of middle segment stricture. The separation of the renal pelvis on the affected side was 3.2 (2.1, 4.2) cm. The length of ureteral stricture was 3.8 (2.5, 4.3) (1.0-5.0) cm, and the preoperative blood creatinine was 90(71, 97)μmol/L. Robot-assisted laparoscopic ventral onlay lingual mucosal graft ureteroplasty was performed in all cases under general anesthesia. The strictured ureter segment was separated and longitudinally cut during the operation. The lingual mucosal grafts 2.5-5.0 cm in length and 1.0-1.5 cm in width was cut according to the stricture. Then the lingual mucosal grafts were harvested and placed in the strictured ureter as a ventral onlay. One double J tube was placed in the affected side in all cases during operation. The perioperative outcomes and complications were analyzed. The blood creatinine and renal pelvis separation on the affected side after surgery were compared with the preoperation.Results:All the surgeries were successfully completed. The average operative time was (190.8 ± 59.0) min, median blood loss was 40 (20, 63) ml, postoperative indwelling time of the drainage tube was 6 (4, 6) days, gastrointestinal function recovery time was 3 (2, 3) days, postoperative hospital stay was 6 (6, 7) days. The patients had clear pronunciation and lingual incision recovered 1 week post-operatively. The urine tube was removed 2 weeks after surgery, and the double J tube was removed 8 (6, 10) weeks post-operatively. Radiological examination revealed significant difference in hydronephrosis on the affected side 3 months post-operatively compared with the preoperation, and the separation of the renal pelvis on the affected side was 1.2 (1.2, 1.4) cm after surgery. The blood creatinine was 79(71, 104)μmol/L at 3 month after surgery, which was also improved compared with preoperative.Conclusions:Robot-assisted laparoscopic ventral onlay lingual mucosal graft ureteroplasty is a feasible and safe option for the treatment of ureteral stricture with less trauma, rapid recovery, and less complications.

OBJECTIVETo study serum concentration and mRNA expression of interleukin-13 (IL-13) in children with steroid-responsive nephrotic syndrome (SRNS) and the effect of methylprednisolone pulse therapy (MPT) on IL-13 expression.

METHODSTwenty-eight children with SRNS were enrolled in this study. Serum protein level of IL-13 was measured using ELISA and IL-13 mRNA expression in peripheral blood mononuclear cells (PBMC) was detected with RT-PCR before MPT, 2 and 5 days after MPT, and 2 weeks after disappearance of proteinuria following MPT. Twenty-four urinary protein was measured with the biuret assay. Twenty healthy children were used as controls.

RESULTSSerum IL-13 levels (38.48 +/- 13.01 pg/mL vs 5.18 +/- 2.71 pg/mL) and PBMC IL-13 mRNA expression (1.31 +/- 0.23 vs 0.36 +/- 0.07) before MPT in SRNS patients were significantly higher than in the controls. After 5 days of MPT and 2 weeks after disappearance of proteinuria following MPT, serum IL-13 levels (15.33 +/- 7.81 and 5.35 +/- 2.12 pg/mL respectively) and PBMC IL-13 mRNA expression (0.89 +/- 0.26 and 0.33 +/- 0.08 respectively) were significantly reduced (P < 0.01). Serum IL-13 levels and PBMC IL-13 mRNA expression in SRNS patients 2 weeks after disappearance of proteinuria following MPT were reduced to control levels, but remained at a higher level than controls 5 days after MPT. A positive correlation was found between serum levels of IL-13 and 24-hour urinary protein in SRNS patients before (r=0.75, P < 0.01) and after 2 and 5 days of MPT (r=0.68, r=0.71 respectively; P < 0.05).

CONCLUSIONSSerum IL-13 levels and PBMC IL-13 mRNA expression in children with SRNS increase. MPT can inhibit the expression of protein and mRNA of IL-13 in these patients.

OBJECTIVETo clone the coding gene of the stage-specific antigen cC1 from Cysticercus cellulosae and express high levels of soluble cC1 in E.coli.

METHODSThe cC1 gene was amplified from Cysticercus cellulosae by RT-PCR and cloned into pMD18-T vector, followed by subcloning into the prokaryotic expression plasmid pET28a. The recombinant plasmid was transformed into E.coli BL21(DE3) and the expression conditions were optimized. The expressed product was purified by Ni(+)-affinity chromatography, analyzed by high-performance liquid chromatography (HPLC), and identified with SDS-PAGE and Western blotting.

RESULTSThe fragment length of the amplification product by RT-PCR was 1056 bp. Comparison of the amplified gene sequence with the cC1 gene in Genbank identified a samesense point mutation at 423 position in the gene cloned into the expression plasmids. After a 6-h induction with 0.05 mmol/L IPTG at 37 degrees celsius;, the expression of the 40 kd soluble fusion protein exceeded 60% of the total bacterial protein, and the fusion protein was recognized by Cysticercus-infected human sera. The purity of the fusion protein was about 94% after purification by affinity chromatography.

CONCLUSIONThe stage-specific antigen cC1 from Cysticercus cellulosae has been successfully cloned and the soluble protein efficiently expressed in E.coli, which provides the basis for its further study and application.

OBJECTIVETo evaluate the clinical use of virtual endoscopy in the traumatic ossicular chain disruption with intact tympanum pre- and post-operation.

METHODSThe series consisted of 17 cases with temporal bone fracture and 4 cases with tympanum contusion. All were examinated with a high resolution spiral CT by axial and oblique coronal planes of the temporal bone. Three-dimensional reconstruction was processed using the virtual endoscopy software. Ten cases of traumatic ossicular chain disruption were performed with intact canal wall epitympanum approach Ossicular reposition. Eleven patients with facial paralysis were performed ossiculoplasty and facial nerve decompression. Nine cases re-examinated virtual endoscopy after operation.

RESULTSSeventeen cases with temporal bone fractures and traumatic ossicular chain disruption, including 3 cases with the long process of the incus fracture, 9 cases with incus bone dislocation, and 5 cases with incus shedding. In the 4 cases of tympanum contusion, 2 cases with incus bone dislocation, 2 cases with incus bone shedding. The axial plane of temporal bone CT could only showed the fracture line and the hammer and incus bone irregular shape. Perioperatively virtual endoscopy showed hammer incus joint separation, incus stirrup dislocation and joint deformation. Surgery confirmed that the incus body was torn off below the hammer following bone displacement, soft tissue wrapped articular surface, incus and stapes just connected with soft tissue. During the tympanum contusion operation could see incus bone-shedding was valgus. Three to six months after surgery, re-examinated virtual endoscopy showed incus bone dislocation ossicular chain was restored to normal, temporal bone shedding ossicular chain connecting almost intact Hearing increased significantly to the level of practical hearing. The coincidence of traumatic disruption of the ossicular chain by virtual endoscopy and surgery was 100%.

CONCLUSIONVirtual endoscopy was valuable for providing accurate assessment and individual program for treating and following-up the traumatic ossicular chain disruption.
