Objective To discuss the reasons,surgical procedures and prognosis of multiple-operations for intra-and extrahepatic cholangiolithiasis.Methods The retrospective cohort study was adopted.The clinical data of 85 patients with intra-and extrahepatic cholangiolithiasis who underwent multiple-operations at the Second Affiliated Hospital of Anhui Medical University from January 2006 to January 2015 were collected.Individualized operations were determined according to the distribution of stones and liver functional reserve,including stones removal by incising bile duct and external biliary drainage,Roux-en-Y hepaticojejunostomy and hepatolobectomy or segmental hepatectomy.The treatment followed the principles as complete removal of stones,complete resection of lesions,correction of stenosis and adequate drainage.Bile was extracted during operation for bacilli culture.Patients received the postoperative symptomatic treatments,including anti-inflammation,hemostasis,liver protection,acid inhibition and nutritional support.The observation indicators included reoperation reasons,operation method,operation time,volume of intraoperative blood loss and transfusion,hepatic inflow occlusion,stone clearance rate,postoperative complications and treatments,bacilli culture of bile,results of pathological examination and duration of hospital stay,results of follow-up.The follow-up using outpatient examination and telephone interview was performed to detect postoperative living conditions and results of abdominal ultrasound once every 3 or 6 months in patients without stone residue and once every 1 month in patients with stone residue from postoperative week 6 to December 2015.Measurement data with normal distribution and with skewed distribution were represented as x ± s and M (range),respectively.Results (1) Reasons of reoperation:85 patients had stone residue or recurrence,including 7 combined with stenosis of bilioenteric anastomosis,5 with secondary malignant biliary tumors and 2 with gastrointestinal stromal tumor invading intrahepatic bile duct.(2) Intraoperative status of reoperation:of 85 patients,25 received partial hepatectomy + stones removal by incising common bile duct + choledochoscopy exploration + T-tube drainage,21 received partial hepatectomy + stones removal by incising common bile duct + choledochoscopy exploration + Roux-en-Y hepaticojejunostomy,13 received stones removal by incising common bile duct + choledochoscopy exploration + T-tube drainage,8 received stones removal by incising common bile duct + choledochoscopy exploration + Roux-en-Y hepaticojejunostomy,5 received partial hepatectomy + removal of former bilioenteric anastomosis + choledochoscopy exploration + T-tube drainage,4 received former intestinal Y-loop resection + stones removal by choledochoscopy + Roux-en-Y hepaticojejunostomy,3 received stones removal by incising intrahepatic bile duct + choledochoscopy exploration + T-tube drainage,3 received partial hepatectomy + residual gallbladder resection + stones removal by incising common bile duct + choledochoscopy exploration + Roux-en-Y hepaticojejunostomy,2 received partial hepatectomy + residual gallbladder resection + stones removal by incising common bile duct + choledochoscopy exploration + T-tube drainage and 1 received residual gallbladder resection + removal of former bilioenteric anastomosis + choledochoscopy exploration + Roux-en-Y hepaticojejunostomy.Operation time and volume of intraoperative blood loss of the 85 patients were (259 ± 66) minutes and (180 ± 142) mL,respectively.Seven patients underwent intraoperative blood transfusion and 17 underwent first hepatic hilum occlusion.ALl the 85 patients received intraoperative choledochoscopy exploration.The immediate and final stone clearance rates were 62.4% (53/85) and 87.0% (67/77).(3) Postoperative status of reoperations:of 85 patients,45 had postoperative complications.Sixteen patients with incision infection were improved by wound drainage and dressing,anti-infection and supporting treatments without other treatments.Ten patients with pleural effusion were out of hospital after effective anti-infection and nutritional support treatments.Eight patients with biliary fistula were discharged from hospital after abdominal drainage.Six patients with incision infection combined with pleural effusion were discharged from hospital after wound drainage and dressing,anti-infection and nutritional support treatments.Among 5 patients with bile duct bleeding,1 was self-healing,1 underwent reoperation and 3 were improved by conservative treatment.The bacilli culture of bile in 68 patients was positive,and bacteria mainly consisted of Escherichia coli,Enterobacter cloacae,Pseudomonas aeruginosa and Klebsiella pneumoniae.Of 85 patients,78,5 and 2 patients were respectively confirmed with hepatolithiasis,bile duct cell adenocarcinoma combined with stone recurrence and choledocholithiasis combined with interstitialoma by pathological examination.Duration of hospital stay was (21 ±8)days.(4) Results of follow-up:77 patients were followed up for a median time of 32 months (range,6-108 months) with an overall follow-up rate of 90.6% (77/85).During follow-up,50 patients had good survival,27 had poor survival including 11 with stone residue,9 with stone recurrence and 7 with bile duct canceration,and 7 died of no operation of secondary tumors.Conclusions Stone residue and recurrence are the main reasons for reoperation.The individualized surgical methods are determined according to preoperative stone distribution,with or without atrophy of liver lobe,with or without canceration and condition of liver function,which can increase the stone clerance rate,reduce the stone residue and recurrence rates and avoid reoperation.

Journal of Shanghai Jiaotong University(Medical Science) 2020;40(7):916-922
Objective: To compare the clinical efficacy of cross puncture technique with traditional puncture technique in the treatment of osteoporotic vertebral compression fracture (OVCF). Methods: Patients with OVCF treated with percutaneous vertebroplasty (PVP) were selected. According to the puncture method, the patients were divided into cross puncture group and traditional puncture group, with 70 cases in each group. The clinical data, imaging parameters, pain score, dysfunction score, overall satisfaction and related complications of the two groups were compared before and after operation, and the clinical efficacy of the two groups was evaluated. Results: Compared with the traditional puncture group, the wedge angle in the cross puncture group decreased at 6 and 12 months after operation (both P=0.000), while the leading edge height increased (P=0.012, P=0.000). During the follow-up, there was no significant difference in pain score and dysfunction score between the two groups. Compared with the traditional puncture group, the proportion of the excellent and great grades (Odom standard) of patients in the cross puncture group was higher (P=0.000, P=0.003), and the incidence of vertebral collapse, kyphosis deformity and spinal stenosis were lower (P=0.000, P=0.002, P=0.031). Conclusion: At 6 and 12 months after operation of cross puncture PVP, the follow-up changes of wedge angle and leading edge height of vertebral body were smaller than those of traditional puncture technique, that is, more stable. The incidence of vertebral collapse was lower, and the overall satisfaction of the curative effect was higher.

ObjectiveTo evaluate the curative effect difference between Tong's anterior mesh suspension and modified tension-free vaginal tape-obturator (TVT-O). Methods75 SUI cases were random divided into two groups: Group A (35 cases) were accepted Tong's anterior mesh suspension and group B (40cases) were accepted modified tension-free vaginal tape- obturator. Curative effects, operation safety,and complications and so on, were recorded and compared. ResultsThere had no statistical differences between these two groups on operation time, bleeding lose, operation injury, immediate postoperative urinary retention andcure rates, but the operation expense of group A was cheaper than group B [ (980. 74 ±212.45)yuan vs (2879.06 ±467. 13)yuan , P <0.05). ConclusionThe curative effect between two methods were similar. It's a little complicated and fit to be popularized in large hospital to modified tensionfree vaginal tape-obturator. Tong's anterior mesh suspension was performed under completely direct vision,not through pelvic cavity, and it was an economic, convenient and easy way, which not only fit to be popularized in basic hospital, but also a surgical remedial measure to the failures who accepted these operations,such as TVT, SPARC, IVS, MONARC, TOT, TVT-O, etc.

OBJECTIVETo study the relationship between clinical syndromes and X-ray manifestation of knee osteoarthritis (KOA), so as to provide evidence for clinical diagnosis and treatment.
METHODSSeventy-eight patients (108 knees) with KOA from out-patient clinic of orthopedic were collected, aged from 41 to 77, including 65 females (89 knees) and 13 males (19 knees). Questionnair investigation of Lequesne index was performed among all these patients and the Lequesne index was calculated. And all these patients were divided into two groups, mild group (Lequesne index < or = 8) and severe group (Lequesne index > 8). Weight-bearing anteriorposterior and lateral plain film of knee joint and patellofemoral Skyline plain flim was taken. Joint space narrowing, osteophyte formation, subchondral osteosclerosis and subchondral cystic degeneration were evaluated. The lower limb alignment and lateral patella angle were detected. The correlation of the Lequesne index and X-ray manifestation was analyzed by logistic regression analysis.
RESULTSThere were significant differences between mild and severe groups in the following indexes: lateral tibiofemoral joint space narrowing, the medial retropatellar space narrowing, medial and lateral tibia osteophytes, medial and tibial femur femur osteophytes, medial and lateral trochlea osteophytes, lateral patella osteophytes, tibia introcondylar osteophytes (P<0.05). The results of the logistic regression analysis showed that the lateral femur osteophytes were the most important radiologic manifestation to evaluate the severity degree of KOA,with the minimum associated probability (0.009) and the maximum wald value (6.779).
CONCLUSIONWhen evaluating the severity degree of KOA,the joint space narrowing and osteophytes are the most sigenificant radiologic manifestation which includs the lateral tibiofemoral joint space narrowing, the medial retropatellar space narrowing, medial and lateral tibia osteophytes, medial and lateral femur osteophytes, medial and lateral trochlea osteophytes, lateral patella osteophyte, tibial intercondylar osteophyte.

OBJECTIVETo explore a method of isolation, culture and chondrogenic phenotype differentiation of mesenchymal stem cell (MSCs) from the bone marrow of rats in vitro and to offer experimental reference for the resources of seeding cells in cartilage tissue engineering.
METHODSMSCs were isolated from bone marrow and purified by density gradient centrifuge and cultured in vitro. The MSC adherence formed and those in passage 3 were chosen to induce into chondrogenic differentiation. After 7, 14, 21 days, immunohistochemical techique was applied to detect the expression of collagen type II. The differentiated cells were implanted on the CPP/PLLA composites. After the cell-scaffold complex was cultured in vitro for one week, the ultrastructure of the scaffold was observed with scanning electron microscopy.
RESULTSThe differentiated cells changed from a spindle-like fibroblastic appearance to a polygonal shape, the capability of proliferation was down markedly. Immunohistochemical staining of collagen II were positive for the pass age, especially in the 21st days. Induced MSCs were well adherent to the scaffold composites and the cells were embedded by the cell-matrix.
CONCLUSIONUnder the induced medium, MSCs can differentiate into chondrogenic phenotype and secrete specificity matrix of cartilage in vitro. MSCs can likely be served as optimal cell source for cartilage tissue engineering.
