Abstract
BACKGROUND Robotic surgery is a cutting-edge minimally invasive technique that overcomes many shortcomings of laparoscopic techniques, yet few studies have evaluated the use of robotic surgery to treat Hirschsprung’s disease (HSCR).
AIM To analyze the feasibility and medium-term outcomes of robotic-assisted proctosigmoidectomy (RAPS) with sphincter- and nerve-sparing surgery in HSCR patients.
METHODS From July 2015 to January 2022, 156 rectosigmoid HSCR patients were enrolled in this multicenter prospective study. Their sphincters and nerves were spared by dissecting the rectum completely from the pelvic cavity outside the longitudinal muscle of the rectum and then performing transanal Soave pull-through procedures. Surgical outcomes and continence function were analyzed.
RESULTS No conversions or intraoperative complications occurred. The median age at surgery was 9.50 months, and the length of the removed bowel was 15.50 ± 5.23 cm. The total operation time, console time, and anal traction time were 155.22 ± 16.77, 58.01 ± 7.71, and 45.28 ± 8.15 min. There were 25 complications within 30 d and 48 post-30-d complications. For children aged ≥ 4 years, the bowel function score (BFS) was 17.32 ± 2.63, and 90.91% of patients showed moderate-to-good bowel function. The postoperative fecal continence (POFC) score was 10.95 ± 1.04 at 4 years of age, 11.48 ± 0.72 at 5 years of age, and 11.94 ± 0.81 at 6 years of age, showing a promising annual trend. There were no significant differences in postoperative complications, BFS, and POFC scores related to age at surgery being ≤ 3 mo or > 3 mo.
CONCLUSION RAPS is a safe and effective alternative for treating HSCR in children of all ages; it offers the advantage of further minimizing damage to sphincters and perirectal nerves and thus providing better continence function.

Abstract
BACKGROUND Most commonly, cyst excision and Roux-en-Y hepaticojejunostomy reconstruction are the optimal treatment for choledochal cysts (CC). Robotic surgery (RS) is being conducted with increasing frequency to treat CC. It is unclear whether RS can overcome the limitations of laparoscopic surgery (LS) and improve the prognosis of patients. In terms of efficacy, evidence concerning which minimally invasive surgery is preferred is, however, sparse. Our objective is to further compare the efficacy of RS and LS in children with CC and draw a useful clinical conclusion. METHODS Studies meeting inclusion criteria were identified from a series of databases, consisting of PubMed, Embase, Scopus, Web of Science, the Cochrane Library and their reference list of articles up to May 2022. Eligible articles comprised at least five objects that were younger than 18 years of age and the language was limited to English. Two authors independently evaluated selected studies and extracted data for analysis. RESULTS Forty studies were selected for analysis, with thirty-six reporting data on LS and eight containing data on RS. The pooled conversion rate and pooled postoperative complication rate of RS were lower than those of LS, but none of them was statistically significant. Moreover, comparisons of the following detailed postoperative complication rates were not statistically significant, such as intestinal obstruction or ileus, anastomotic bleeding, anastomotic or bile leakage, and anastomotic stenosis. However, the intraoperative blood loss and the postoperative hospital stay in RS group were significantly lower than those in LS group. CONCLUSIONS RS is a safe and feasible option for children with CC. Further studies with more cases, long-term efficacy and health economics analysis are needed to confirm whether RS is more advantageous.

Abstract
BACKGROUND Though conventional thoracoscopic plication is a favorable option of diaphragmatic eventration (DE), ribs limited the movement of trocars, making it difficult to suturing, knot-tying and time-consuming. The purpose of this study was to evaluate delicate surgical maneuvers and suturing time for the management of DE in robot-assisted thoracoscopic plication (RATP). METHODS From January 2015 to November 2019, 20 patients (14 males; mean age: 10.5 ± 5.2 months; mean weight: 8.6 ± 4.5 kg) who underwent diaphragmatic plication for DE were reviewed at our institution. There were 13 patients with congenital diaphragmatic eventration and 7 patients with acquired diaphragm eventration after congenital heart surgery. RATP was performed on 9 patients (3 on the left and 6 on the right), and conventional thoracoscopic plication (CTP) was applied to 11 patients (5 on the left and 6 on the right). Demographics, the suturing time and complications were respectively evaluated. RESULTS There was no difference between 2 groups with respect to gender, age at surgery and weight (p > 0.05). No conversion to thoracotomy was needed. The suturing time in RATP group was shorter than CTP group (27.7 ± 3.4 min vs 48.1 ± 4.2 min, p < 0.001). One patient (9.09%) experienced recurrence in CTP group and none was found in RATP group. CONCLUSIONS Diaphragmatic plication with robot-assisted thoracoscopy or conventional thoracoscopy in DE has minimally invasive and good effect on children. RATP overcome the intercostal limitations to complete delicate suturing and free knot-tying, and has better ergonomics. LEVEL OF EVIDENCE Level III.

Abstract
BACKGROUND A one-stage laparoscopic operation has recently been considered a favorable option for the management of patients with Hirschsprung's disease (HD) due to its superior cosmetic results. One-stage transanal endorectal pull-through for the treatment of rectosigmoid HD has been widely used in newborns without complications. However, enterostomy is required in some HD cases for enterocolitis and dilated colon. Our transumbilical enterostomy (TUE) and two-stage laparoscopy-assisted anorectoplasty were effective and achieved a similar cosmetic effect to one-stage laparoscopy on the abdominal wall in patients with anorectal malformation, but the effect in patients with HD is unclear.
AIM To evaluate the safety, efficacy and cosmetic results of TUE in two-stage laparoscopy-assisted pull-through for HD.
METHODS From June 2013 to June 2018, 53 patients (40 boys, 13 girls; mean age at enterostomy: 5.5 ± 2.2 mo) who underwent enterostomy and two-stage laparoscopy-assisted pull-through for HD with stoma closure were reviewed at our institution. Two enterostomy approaches were used: TUE in 24 patients, and conventional abdominal enterostomy (CAE) in 29 patients. Eleven patients with rectosigmoid HD had severe preoperative enterocolitis or a dilated colon. 26 patients had long-segment HD, and 16 patients had total colonic aganglionosis (TCA). The patients with left-sided HD underwent the two-stage laparoscopic Soave procedure, and the patients with right-sided HD and TCA underwent the laparoscopic Duhamel procedure. Demographics, enterostomy operative time, complications and cosmetic results were respectively evaluated.
RESULTS There were no differences between the groups with respect to gender, age at enterostomy, weight and clinical type (P > 0.05). No conversion to open technique was required. Two patients experienced episodes of stomal mucosal prolapse in the TUE group and 1 patient in the CAE group (8.33% vs 3.45%, P > 0.05). No parastomal hernia was observed in either of the two groups. Wound infection at the stoma was seen in 1 case in the TUE group, and 2 cases in the CAE group (4.17% vs 6.90%, P > 0.05). No obstruction was noted in any of the patients in the TUE group, whereas obstruction was found in 1 patient in the CAE group. Enterocolitis was observed in 3 and 5 patients in the TUE and CAE group, respectively (12.50% vs 17.24%, P > 0.05). There was no significant difference between the TUE group and CAE group in terms of the incidence of soiling and constipation (P > 0.05). The cosmetic result using the scar score in the TUE group was better than that in the CAE group (6.83 ± 0.96 vs 13.32 ± 1.57, P < 0.05).
CONCLUSION TUE is a safe and feasible method for the treatment of HD, and the staged enterostomy and two-stage laparoscopy-assisted pull-through achieved a similar cosmetic effect to the one-stage laparoscopic procedure.

Abstract
A new coordination polymer [Cd(C10H8N2)2 (C10H4O8)]
n
(C10H8N2 = 2,2′-bipyridine and C10H4O8 = 2,5-dicarboxybenzene-1,4-dicarboxylate) has been hydrothermally synthesized and characterized by elemental analysis, infrared spectroscopy, thermal gravimetric analysis and single-crystal X-ray diffraction. Crystal structural analysis reveals that the CdII cation is coordinated by two 2,5-dicarboxybenzene-1,4-dicarboxylate ligands and two 2,2′-bipyridine molecules, forming a distorted octahedral CdN4O2 coordination geometry. The 2,5-dicarboxybenzene-1,4-dicarboxylate ligands link the CdII cations to generate a one-dimensional metal-organic structure running along the [0 1 0] direction. Adjacent chains are further connected by carboxyl-carboxyl O–H···O hydrogen bonds, resulting in a two-dimensional supermolecular architecture running parallel to the (1 0 0) plane in the solid state. The fluorescence properties of the complex were investigated.

Abstract
In the complex cation of the title salt, [Co(C12H8N2)3](C10H5O8)2·H2O, the CoII cation is situated on a twofold rotation axis and is coordinated in a distorted octahedral manner by six N atoms from three chelating 1,10-phenanthroline (phen) ligands. In the crystal, the non-coordinating 2,4,5-tricarboxybenzoate anions interact with each other via O—H...O hydrogen bonds, generating a two-dimensional network parallel to (100). Adjacent sheets are connected by waterO—H...Ocarboxylate hydrogen bonds, resulting in a three-dimensional network structure that surrounds the complex cations.

Abstract
AIM To assess the diagnostic value of a laparoscopic finding of a hepatic subcapsular spider-like telangiectasis (HSST) sign in biliary atresia.
METHODS A retrospective study was conducted first and then a validation set was used to investigate the value of an HSST sign in predicting biliary atresia (BA). In the retrospective study, laparoscopic images of the liver surface were reviewed in 126 patients with infantile cholestasis (72 BA patients and 54 non-BA cholestasis patients) and a control group of 38 patients with non-hepatic conditions. Analysis was first made by two observers separately and finally, a consensus conclusion was achieved. Then, the diagnostic value of the HSST sign was validated in an independent cohort including 45 BA and 45 non-BA patients.
RESULTS In the retrospective investigation, an amplified HSST sign was found in all BA patients, while we were unable to detect the HSST sign in 98.1% of the 54 non-BA patients. There was no HSST sign in any of the control subjects. In the first review, the sensitivity and specificity from one reviewer were 100% and 98.1%, respectively, and the results from the other reviewer were both 100%. The consensus sensitivity and specificity were 100% and 98.1%, respectively. The HSST sign was defined as being composed of several enlarged tortuous spider-like vascular plexuses with two to eight branches distributed on all over the liver surface, which presented as either a concentrated type or a dispersed type. In the independent validation group, the sensitivity, specificity, positive predictive value and negative predictive value of the HSST sign were 100%, 97.8%, 97.8% and 100%, respectively.
CONCLUSION The HSST sign is characteristic in BA, and laparoscopic exploration for the HSST sign is valuable in the diagnosis of BA.

Abstract
Objective: To discuss the correlation of permeability surface (PS) with hematoma and edema volume in acute spontaneous putaminal and thalamic hematoma using CT perfusion imaging. Methods: A total of 48 acute spontaneous putaminal and thalamic hemorrhage patients were enrolled in this study during October 2015 and December 2016 at the First Affiliated Hospital of Wenzhou Medical University. At the image slice with maximum size of hematoma, PS was measured by drawing various regions of interest (ROI) including"hot spots", perihematomal regions, outward regions, hemisphere regions and contralateral mirror regions. The relative PS (rPS) was calculated as the ratio of ipsilateral to contralateral PS value in each ROI. Hematoma and edema volumes were traced and obtained with commercial software. Results: The"hot spots"PS ((2.8±1.5) ml·100 g(-1)·min(-1)) and perihematomal PS ((2.1±1.4) ml·100 g(-1)·min(-1)) were both significantly higher than the PS of the contralateral mirror regions ((1.1±0.5) ml·100 g(-1)·min(-1)) (P<0.001). There was no significant difference in outward regions PS and contralateral mirror regions PS (P>0.05), nor in hemisphere regions PS and contralateral mirror regions PS (P>0.05). There was no significant difference in"hot spots"rPS and perihematomal rPS (P=0.218). The"hot spots"rPS and Perihematomal rPS were both higher than the rPS of the outward and hemisphere regions (P<0.01). There was no significant difference in the outward and hemisphere regions (P<0.01). The median hematoma volume was 12.63 ml and the median edema volume was 12.36 ml. The edema volume had a positive association with the hematoma volume(r=0.799, P<0.001) and perihematomal PS(r=0.465, P=0.001). Perihematomal PS had a positive association with the hematoma volume (r=0.386, P=0.007). Conclusion: The damage of blood-brain barrier around acute spontaneous hematoma can be measured via CT perfusion imaging. Perihematomal PS was associated with the hematoma and edema volume.

Abstract
BACKGROUND Increased defecation frequency and soiling are common complications of surgery for right-sided Hirschsprung's disease (HD). Though the laparoscopic Duhamel procedure is a favorable option in right-sided HD, the conventional laparoscopic technique is time consuming and has complications that are associated with the reservoir. In this study, we described a modified laparoscopic Duhamel technique with ex-anal rectal transection combined with the Deloyer's procedure for right-sided HD. MATERIALS AND METHODS Between March 2010 and January 2015, 18 right-sided HD underwent this modified laparoscopic Duhamel procedure (MLDP). The main modifications were to mobilize the colon and to dissect the retrorectal space under laparoscopy, pull out, and transect ex-anally by using a linear stapling device through a transverse incision on posterior wall of the rectum. Seven age-matched patients who underwent a conventional laparoscopic Duhamel procedure (CLDP) between March 2008 and December 2010 were included as the control group. Demographics, surgical procedures, operative data, postoperative complications, and clinical outcomes were compared between these two groups. RESULTS Operative time was significantly shorter in the MLDP group (150 minutes versus 195 minutes; P = .03). There was no significant difference in mean timespan to obtain a normal defecation frequency (3.8 months versus 3.6 months), incidence of soiling (11.1% versus 14.3%; P = .34), and constipation (5.6% versus 14.3%; P = .69). Pouchitis were not found in the MLDP group, whereas 2 patients in the CLDP group (28.6%) presented with pouchitis and intractable diarrhea, requiring spur division. The incidence of postoperative enterocolitis was not significantly different in the two groups (11.1% in MLDP versus 14.3% in CLDP; P = .68). All 22 patients had a normal defecation over 4 years of age. CONCLUSIONS Laparoscopic Duhamel with ex-anal rectal transection is a simple, easy-to-learn, and effective procedure for right-sided HD. It has low postoperative pouchitis because of a short pouch.

Abstract
OBJECTIVE To investigate the optimal anticoagulation methods and monitoring strategy for Chinese patients undergoing heart valve replacement, which is potentially quite different from western populations. METHODS In this multicenter prospective cohort study, the anticoagulation and monitoring strategy data was acquired from 25 773 in-hospital patients in 35 medical centers and 20 519 patients in outpatient clinic in 11 medical centers from January 1st, 2011 to December 31th, 2015. RESULTS As for in-hospital patients, mean age of study population was (48.6±11.2) years old; main etiology of valve pathology was rheumatic (87.5%) origin among study cohort; 94.8% of study population received mechanical valve implantation; international normalized ratio (INR) monitoring (in all the study centers) and low-intensity anticoagulation strategy (31 hospitals chose target INR range of 1.5-2.5, and actual values of INR among 89.2% of 100 069 in-hospital monitoring samples were 1.5-2.5), with mean actual INR values of 1.84±0.53, and warfarin dosage of (2.82±0.93) mg/d were widely adopted among the study centers; strategies of in-hospital warfarin administration were similar in all the study centers; complication rates of low-intensity anticoagulation strategy were low in severe hemorrhage (0.02%), thrombosis (0.05%), and thromboembolism (0.05%) events, without anticoagulation-related death.As for 18 974 outpatient clinic patients, the follow-up rate was 92.47%, with a total of 30 012 patient-years (Pty). Anticoagulation-related morbidity and mortality rates were 0.67% and 0.15% Pty; major hemorrhage morbidity and mortality rates were 0.25% and 0.13% Pty; thromboembolism morbidity and mortality rates were 0.45% and 0.03% Pty.The mean dosage of warfarin daily dosage was (2.85±1.23) mg/d and INR value was 1.82±0.57.No significant regional difference in the intensity of anticoagulation therapy was noted during the study. CONCLUSIONS INR can be used as a normalized indicator for intensity of anticoagulation therapy in China.The optimal anticoagulation intensity with INR range from 1.5 to 2.5 is safe and effective for Chinese patients with heart valve replacement, and there is no significant regional difference in the intensity of anticoagulation therapy.

Abstract
Objective: To investigate the change of cerebral microcirculation of chronic cerebral circulation insufficiency(CCCI) patients and the relationship between CCCI and crossed cerebellar diaschisis(CCD)by using 320-detector row of low-dose volume CT perfusion imaging. Methods: A total of 158 patients (103 males, 55 females, from 45 to 82 years old, the mean age was 62.9) with symptoms of CCCI were admitted to the First Affiliated Hospital of Wenzhou Medical University from June 2013 to January 2016. Low-dose CTP imaging of whole brain was performed to them using 320-detector row volume CT scanner. The perfusion parameters such as cerebral blood flow(CBF), cerebral blood volume(CBV), mean transit time(MTT), time to peak(TTP) and DLY in both cerebral blood supply areas and cerebellum were got, so were the 4-dimensional CTA images, and rCBF, rCBV, rMTT and rTTP were calculated by ipsilateral/contralateral value. Comparative t-test and independent t-test were applied to analyzing these parameters quantitatively.Chi-square test and Logistic regression model were applied to analyzing the related clinical risk factors. Results: (1) All 108 patients in CCCI group showed asymmetric perfusion within two cerebral hemispheres in CTP images. The CBF, CBV of diseased side were lower than the contralateral mirror area (t(CBF)=-12.89, t(CBV)=-7.031, P(CBF, CBV)<0.001); the MTT of the diseased side was shorter than the contralateral mirror area (t(MTT) =13.310, P(MTT)<0.001); the TTP of the diseased side was longer than the contralateral mirror area (t(TTP)=-4.012, P(TTP)<0.001). The rCBF and rCBV of CCCI group were lower than that in non-CCCI group (t(rCBF)=3.079, t(rCBV)=2.760, P(rCBF, rCBV)<0.01), while the rTTP of CCCI group was longer than that in non-CCCI group (t(rTTP)=4.846, P(rTTP)<0.001). (2)The results of Chi-square test showed that the differences of gender (χ(2)=4.036, P=0.045), hyperlipidemia (χ(2)=7.687, P=0.006), as well as smoking (χ(2)=11.868, P=0.001) had statistical significance between CCCI group and non-CCCI group.Multi-factor Logistic regression analysis showed that hyperlipidemia (OR value=3.736, P=0.016) and smoking (OR value=4.641, P=0.01) were the risk factors of CCCI, while gender had no relationship with it.(3)The incidence of CCD was 18.5% in the CCCI group, and at the same time, the supratentorial corresponding blood supply areas were classified.A total of 10(34.5%) cases were in blood supply area of posterior cerebral artery, 6(20.7%) cases were in blood supply area of middle cerebral artery, 12(41.4%) cases were of anterior cerebral artery, while only 1(3.5%) case was of basal ganglia, in which 4 cases were in blood supply area of posterior cerebral artery, another 4 cases were middle cerebral artery, 7 cases were of anterior cerebral artery and no case of basal ganglia respectively leading CCD alone. Conclusions: CTP could display the microcirculation situation of abnormal brain tissue perfusion area intuitively and quantitatively. Additionally, it could reflect the degree of relationship between cerebral several blood supply areas and cerebellum.

Abstract
Biliary atresia (BA) is characterized by progressive inflammation of the biliary system leading to liver cirrhosis, necessitating liver transplantation in pediatric patients. Various cell types have been reported to participate in the proinflammatory response in rhesus rotavirus (RRV)-induced BA mouse models, including T helper (Th) 1, Th2, Th17, CD8+ T cells, and natural killer cells. The immune suppressive regulatory T (Treg) cells, on the contrary, were reported not to function properly. The underlying mechanism is largely unknown. Focusing on the impaired suppressive function of Treg, we found methylation status of CpG islands within the Foxp3 promoter region of Treg cells in BA patients and murine models were both increased. Moreover, by injecting 5-aza-2'-deoxycytidine (Aza) as DNA-methylation inhibitor to RRV-infected mice, BA phenotypes were alleviated. Furthermore, Treg cells isolated from "RRV+Aza"-injected mice had better suppressive function than Treg cells from mice injected with RRV only, both in vivo and ex vivo. Thus we concluded that aberrant increased methylation status of "Foxp3 promoter" in Treg cells leads to impaired Treg suppressive function, exacerbating inflammatory injury in BA.

Abstract
To investigate the changes in the proportion of γδ T cells and Foxp3(+) Treg cells in children with BA (biliary atresia). The distribution of γδ T cells in the liver tissues and the proportion of γδ T cells and Foxp3(+) Treg cells were observed and detected in BA Group (32 cases) and control group (CG) (12 cases) by using immunohistochemical methods and flow cytometry. The periportal bile duct of liver in BA Group was surrounded by a large number of γδ T cells and a certain degree of Foxp3(+) Treg cells infiltration. Additionally, the proportion of γδ T cells and Foxp3(+) Treg cells was significantly higher than that in CG (P<0.05). And significantly negative correlation was revealed in the proportion of γδ T cells and Foxp3(+) Treg cells (P<0.05). The increase of γδ T cells or inhibition of Foxp3(+) Treg cell proliferation in liver tissues of patients with biliary atresia exacerbated the progressive inflammatory injury of bile ducts.

Abstract
AIM: To report the clinical outcomes and ergonomics analysis of three laparoscopic approaches in the management of Hirschsprung’s disease (HD).
METHODS: There were 90 pediatric patients (63 boys, 27 girls; mean age: 3.6 ± 2.7 mo; range: 1.0-90.2 mo) who underwent laparoscopic endorectal pull-through Soave procedures for short- and long-segment HD in our hospital. Three laparoscopic approaches were used: conventional laparoscopic pull-through (CLP) in 30 patients between 2009 and 2013, single-incision laparoscopic pull-through (SILP) in 28 patients between 2010 and 2013, and hybrid single-incision laparoscopic pull-through (H-SILP) in 32 patients between 2011 and 2013. We applied the hybrid version of the single-incision approach in 2011 to preserve the cosmetic advantage of SILP and the ergonomic advantage of CLP. We retrospectively analyzed the clinical data, cosmetic results, and ergonomics of these three approaches to have a better understanding of the selection of one approach over another.
RESULTS: The CLP, SILP, and H-SILP groups were similar in regard to age, sex, transition zone, blood loss, hospital stay, and intraoperative complications. Early and late postoperative results were not different, with equal daily defecation frequency and postoperative complications. No conversion to open technique was needed and none of the patients had recurrent constipation. With proper training, the ergonomics challenges were overcome and similar operative times were registered for the general operative time in the patients < 1 year of age and the short-segment HD patients. However, significantly shorter operative times were registered compared to SILP for patients > 1 year of age (CLP and H-SILP: 120 ± 15 min and 119 ± 12 min, respectively, vs 140 ± 7 min; P < 0.05) and for long-segment HD patients (152 ± 3.5 min and 154 ± 3.6 min, respectively, vs 176 ± 2.3 min; P < 0.05). The best cosmetic result was registered with the SILP (scarless), followed by the H-SILP (near scarless appearance) and the CLP (visible scars) procedures.
CONCLUSION: Based on the results, we believed that the laparoscopic approach should be selected according to the age, transition zone, and desired cosmetic result.

Abstract
The importance of the ROP small GTPase signaling pathway in the regulation of cellular polarity growth in eukaryotes has been thoroughly studied. In this study, we examined the LeROP small GTPase (related to Arabidopsis thaliana genome LeROP GTPase in tomato) signaling of cell polarity growth in the mutant (M-1) tomato. Interestingly, we detected expansive growth of epidermis cells in M-1, in which the leaves appeared slightly lobed shaped. However, we observed jigsaw puzzle shaped and deeply lobed shaped leaves in wild-type leaf epidermis cells. The t-test showed significant difference (P < 0.05). Based on previous studies of the AtROP gene in Arabidopsis leaf epidermis cells, we hypothesized that the growth of mutant M-1 tomato leaf epidermis cell is related to AtROP gene signal transmission. The results of reverse transcription-polymerase chain reaction showed the expression of LeROP2, LeROP4, and LeROP7 in M-1 mutants were stronger than in wild-type cells. At the flowering stage, LeROP2 GTPase showed no expression in wild-type cells, but was expressed in mutant cells. This study revealed a link between the low-energy ion beam and the ROP GTPase signaling pathway in tomato. In addition, the ROP gene changes analyzed suggest a new mechanism for mutations following low-energy ion beam implantation.

Abstract
BACKGROUND Trans-umbilical colostomy (TUC) has been previously created in patients with Hirschsprung's disease and intermediate anorectal malformation (ARM), but not in patients with high-ARM. The purposes of this study were to assess the feasibility, safety, complications and cosmetic results of TUC in a divided fashion, and subsequently stoma closure and laparoscopic assisted anorectoplasty (LAARP) were simultaneously completed by using the colostomy site for a laparoscopic port in high-ARM patients. METHODS Twenty male patients with high-ARMs were chosen for this two-stage procedure. The first-stage consisted of creating the TUC in double-barreled fashion colostomy with a high chimney at the umbilicus, and the loop was divided at the same time, in such a way that the two diverting ends were located at the umbilical incision with the distal end half closed and slightly higher than proximal end. In the second-stage, 3 to 7 months later, the stoma was closed through a peristomal skin incision followed by end-to-end anastomosis and simultaneously LAARP was performed by placing a laparoscopic port at the umbilicus, which was previously the colonostomy site. Umbilical wound closure was performed in a semi-opened fashion to create a deep umbilicus. RESULTS TUC and LAARP were successfully performed in 20 patients. Four cases with bladder neck fistulas and 16 cases with prostatic urethra fistulas were found. Postoperative complications were rectal mucosal prolapsed in three cases, anal stricture in two cases and wound dehiscence in one case. Neither umbilical ring narrowing, parastomal hernia nor obstructive symptoms was observed. Neither umbilical nor perineal wound infection was observed. Stoma care was easily carried-out by attaching stoma bag. Healing of umbilical wounds after the second-stage was excellent. Early functional stooling outcome were satisfactory. CONCLUSIONS The umbilicus may be an alternative stoma site for double-barreled colostomy in high-ARM patients. The two-stage laparoscopic approaches for high-ARM, TUC and stoma closure with simultaneously LAARP are both technically feasible and safe with excellent cosmetic result.

Abstract
This study aimed to isolate mesenchymal stem cells from bone mesenchymal stem cells (BMSCs), determine their therapeutic potential for treating rats with acute liver failure (ALF), further explore the factors that induce liver failure mechanisms, and elucidate the role of bone marrow stem cell therapy and BMSCs on liver homing. We found that differentiation potential was present in BMSCs expressing high levels of CD29 and CD90. These cells improved liver functioning in vivo after transplantation into rat livers with D-galactosamine damage, as evidenced by the levels of alanine aminotransferase and aspartate aminotransferase returning to normal (low levels) in recipient ALF rats. A significant improvement in the liver functional test and histological findings was observed in the transplantation group after 120 and 168 h of transplantation (P < 0.05). Histological data revealed that hepatocyte cell apoptosis was lower in the transplantation group compared to the control groups (P < 0.05), and that the transplantation of BMSCs reduced liver inflammation, decreased hepatic denaturation and necrosis, and promoted liver regeneration. These ameliorations were not recorded in the control groups. The results of in situ hybridization, immunofluorescence staining, and Western blot confirmed the presence of transplanted BMSCs in recipient rat livers. Stromal cell derived factor-1 alpha and vascular endothelial growth factor were significantly upregulated after the intraportal transplantation of BMSCs, with significantly higher levels being found in the portal vein and the tail vein groups (P < 0.05). In conclusion, BMSCs have a therapeutic effect against ALF rats, evoke endogenous repair mechanisms in the liver, and may represent a novel form of therapeutic intervention for the disease. Furthermore, intraportal transplantation serves as a more effective pathway compared to tail vein transplantation.

Abstract
The title compound, [Cu(SO4)(C12H8N2)2]·C4H10O2, is comprised of neutral monomeric complex and butane-2,3-diol solvent molecules. In the complex, the CuII ion is in a distorted square-pyramidal coordination environment defined by four N atoms from two chelating 1,10-phenanthroline ligands and one O atom from a monodentate sulfate anion; the O atom is at the apex. The two chelating N2C2 groups subtend a dihedral angle of 85.8 (4)°. In the crystal, the neutral monomeric complex and butane-2,3-diol solvent molecules are held together by O—H⋯O hydrogen bonding, which leads to additional stabilization of the structure. The presence of pseudosymmetry in the structure suggests the higher symmetry space group C2/c, but attempts to refine the structure in this space group resulted in an unsatisfactory model and high R and wR values. The sulfate anion is disordered over two sets of sites with occupancies of 0.55 (1) and 0.45 (1).

Abstract
BACKGROUND Transanal endorectal pull-through was described by De la Torre-Mondragon's technique. In the original transanal pull-through procedure, a long rectal muscular cuff was dissected and left for anocolic anastomosis, which would sometimes lead to postoperative obstructive symptoms and enterocolitis. While a modified short mucosal dissection may increase the risk of injury to pelvic and perirectal nerves and other structures when dissected on the outside of the rectum deep in the pelvis. We report early and late results of the modified transanal procedure for Hirschsprung's disease (HD) over 8 years. METHODS The clinical course of all children with aganglionic rectum or sigmoid colon receiving the modified transanal pull-through between May 2003 and April 2011 were reviewed. The main modifications were rectal mucosa dissection with a long cuff, coloanal anastomosis with a short cuff and a V-shaped partial resection in the posterior wall of the muscular cuff. Children with preliminary stoma or total colonic disease were excluded. RESULTS Short- and long-term follow-up was obtained in 137 patients with HD operated upon by the same surgeon. The aganglionic segment was located in the rectum or sigmoid colon in all patients. The mean age at surgery was 165 ± 74 days. The mean operating time was 108 ± 38 min. Mean intra-operative blood loss was estimated to be 15 ± 10 ml. No patient required a blood transfusion. Mean postoperative hospital stay was 7 ± 2 days. Early postoperative complications included perianal excoriation in 38 patients (27.7 %), enterocolitis in two patients (1.4 %), and anastomotic leak in two patients (1.4 %). Late postoperative complications included perianal excoriation in 16 patients (11.7 %), anal stricture in two patients (1.4 %), constipation in four patients (2.8 %), enterocolitis in 10 patients (7.3 %), and soiling problems in six patients (4.4 %). Mean follow-up was 56 months (6 months-9 years). In patients older than 4 years, 85.4 % of them had excellent/good bowel function, 9.4 % had fair bowel function, and 5.2 % of patients had bad bowel function. CONCLUSION Transanal endorectal pull-through with a long cuff dissection and a short V-shaped resected cuff anastomosis is a safe and effective procedure for HD. It reduced incidence of anastomotic stricture and constipation without an increased soiling incidence.

Abstract
OBJECTIVE The study aimed to build a 3-dimensional (3D) reconstruction of pelvic magnetic resonance images and evaluate the clinical value in anorectal malformations (ARMs). METHODS Magnetic resonance imaging (MRI) examinations were performed on a 1.5-T magnet. Sagittal, coronal, and transverse turbo spin-echo T1-weighted and fast spin-echo T2-weighted images of the pelvic region were obtained in 22 children. A 3D reconstruction was made on a computer and assisted by the 3D-Doctor software (Trial Version, Able Software Corp). The level and type of ARM and the developmental state of the striated muscle complex (SMC) were analyzed with 3D reconstruction image. RESULTS The 3D images of the pelvic were confirmed in 22 cases. Three-dimensional reconstructed images perfectly displayed the anatomical relationships of the SMC and the rectal atresia in these spaces. The 3D configuration of the SMC was different in each of the high- and low-type cases. The high-type malformation of SMCs differed particularly from the descriptions. CONCLUSIONS Pelvic magnetic resonance 3D reconstructed images were able to show the dimensional anatomical relations of pelvis, bladder, urethra, rectum, and SMC. Both a 3D image and positional information with MRI offers the surgeon a simulated operative profile of the SMC superior to MRI slices alone, which will help in providing morphological data for image diagnosis and operation of the ARM.

Abstract
The genetic variations of FUT1 gene at nucleotide position 307 of its open reading frame were investigated by PCR-RFLP in a total of 245 pigs from 3 exotic pig breeds and 3 Chinese native pig breeds. Results showed that the genetic polymorphisms of the FUT1 locus were only detected in the 3 exotic pig breeds. There were 3 different genotypes and the majority were the susceptible forms including GG and AG. All Chinese native pig breeds only presented the susceptible genotype GG. Univariate analysis of variance components indicated that FUT 1 gene and the type of breeds significantly affected total number born, whereas parities did not. None of these factors significantly affected the number of liveborns.

Abstract
QTLs with epistatic effects and environmental interaction effects for final height of rice were studied by mixed-model based QTL mapping with a doubled haploid population from IR64/Azucena in four environments. The results demonstrated the importance of epistasis as a genetic basis of the quantitative traits and also revealed several important features of this phenomenon. In the results, 100 per cent of QTLs were involved in epistasis, of which 64 per cent were found with significant additive effects. This might mean that the usual estimates of the QTL additive effects could be confounded by epistatic interactions and result in biased estimation unless epistatic effect is separated. The other 36 per cent did not have any significant additive effects of their own but were involved in 48 per cent of the identified epistatic interactions. Such loci might play the role of modifying agents that tend to activate other loci or modify the action of other loci. The other features of epistasis include as follows: it was fairly common for the same locus to get involved in interactions with more than one locus; the QTLs with relatively high magnitude of effects might also be involved in epistasis; and epistasis was sensitive to environmental interactions for their expression. QTL x environment (QE) interaction effects were detected more often than QTL main effects for plant height behavior, as might indicate that gene expression could be greatly affected by environments.
