PURPOSE: The most popular surgical approach to manage Lisfranc fracture-dislocations is the double-incision approach, which frequently causes a variety of complications, such as skin necrosis, rotational malreduction of the first tarsometatarsal joint (TMTJ) and lateral column dorsoplantar malreduction of the TMTJ. We introduce a three-incision approach to treat Lisfranc fracture-dislocations with only minor postoperative complications and good foot function. METHODS: We prospectively selected 30 previously healthy patients, ranging from 18 to 60 years of age, but only 23 patients completed the follow-up and thus were finally included, with an average age of 38.1 ± 12.9 years. All patients have sustained Lisfranc fracture-dislocations involving all three-column; 13.0% (3/23) were Myerson classification type A (medial), 47.8% (11/23) were type A (lateral), and 39.1% (9/23) were type C2. All patients were treated via a three-incision approach: a long incision made along the lateral border of the second ray was used as a working incision to visualize and reduce the first three TMTJs, as well as to apply internal fixation instrumentation; a 2 cm medial incision was made at the medial side of the first TMTJ as an inspecting incision, ensuring good reduction of the first TMTJ in medial and plantar view; another 1 cm inspecting incision was made at the dorsal side of the fourth/fifth TMTJ to prevent sagittal subluxation of the lateral column. Mean ± SD was used for quantitative data such as operation time, follow-up time and foot function scores. Postoperative complications were documented, and foot function was evaluated using the American orthopaedic foot & ankle society score, foot function index and Maryland foot score at follow-up. The foot function of the injured foot and contralateral foot of the same patient was at the end of follow-up, and independent sample t-test was used for statistical analysis. RESULTS: The median operation time was 117.9 ± 14.6 min (range 93 - 142 min). All complications occurred within three months after the operation, and included delayed wound healing (17.4%), superficial infection (8.7%), complex regional pain syndrome (4.3%) and neuroma (4.3%). There was no case of postoperative skin necrosis or malreduction. At the end of follow-up of 14.1 ± 1.2 months (range 12-16 months), the median American orthopaedic foot & ankle society score of the operated foot was 89.7 ± 5.7, the median foot function index was 21.7 ± 9.9, and the median Maryland foot score was 88.7 ± 4.8. There were no significant differences between the operated and contralateral sides, in terms of foot function, at the end of followup (p > 0.05). CONCLUSION The three-incision approach can provide adequate visualization of all TMTJs to ensure anatomical reduction and offer sufficient working space to apply internal fixation instrumentation, which is effective in treating three-column Lisfranc fracture-dislocations with minor soft tissue complications and satisfactory functional recovery.

Objective:To investigate and compare the therapeutic effect of Foley catheter balloon dilation and the traditional open reduction in the treatment of intussusception in children.Methods:A total of 68 children with intussusception treated by Foley catheter balloon dilatation by laparoscopic surgery or traditional open reduction in Department of Pediatric Surgery, the Second Hospital of Lanzhou University from August 2015 to July 2019 were retrospectively analyzed.Among them, there were 32 cases in the Foley catheter group and 36 cases in the traditional laparotomy group.Foley catheter group were treated with laparoscopic Foley catheter balloon dilatation, while the traditional open group were treated with traditional open surgery which was performed with finger dilatation.The results of surgical treatment, postoperative recovery, short-term complications, patient satisfaction and long-term complications were compared between the two groups.Results:Among the indexes of surgical treatment effect, the operation time[(0.4±1.1) h], intraoperative bleeding volume[(10.2±3.4) mL], incision size[(0.5±0.4) cm] and incidence of the rupture of intestine[6.3%(2/32 cases)] in the Foley catheter group were significantly lower than those in the traditional open group[(1.3±2.9) h, (40.5±2.1) mL, (5.1±0.7) cm, 30.6%(11/36 cases)], and the differences were statistically significant (all P< 0.05). Among the indexes of postoperative recovery and short-term complications, recovery time of gastrointestinal function[(1.2±3.1) d], length of hospital stay[(6.7±1.8) d], incidence of incision infection[9.4%(3/32 cases)]and incidence of incisional hernia(0) in the Foley catheter group were significantly lower than those in the traditional open group[(3.3±6.4) d, (7.3±0.9) d, 36.1%(13/36 cases), 16.7%(6/36 cases)], and the differences were statistically significant (all P<0.05). Among the indexes of family satisfaction and long-term complications, the score of family satisfaction in the Foley catheter group [(8.7±1.2) scores]was significantly higher than that in the traditional open group[(6.6±3.1) scores], and the incidence of adhesive intestinal obst-ructionin the Foley catheter group (0)was significantly lower than that in the traditional open group[0 vs.19.4%(7/36例)], and the differences were statistically significant(all P<0.05). Conclusions:Compared with traditional open reduction in the treatment of intussusception in children, Foley catheter balloon dilation has the advantages of short operation time, safe operation, low incidence of intestinal injury, less bleeding, and so on, and also has the advantages of small incision, fast recovery, short hospitalization time, high satisfaction of parents.In addition, the Foley catheter balloon dilation has a lower incidence of incisional infection, incisional hernia, postoperative intestinal adhesion and other complications.

Pyroptosis is a form of new programmed cell death which is dependent on Caspase-1 in recent years.When it' s stimulated by various dangerous signals from hepatic ischemia-reperfusion injury,the intracellular pattern recognition receptors are assembled into inflammasomes and Caspase-1 which was transformed into active form.Activated Caspase-1 promotes the maturation and secretion of pro-inflammatory cytokines IL-1β and IL-18,initiates the innate immunity rapidly and then induces severe inflammatory reaction.In addition,Caspase-1 can also cleave Gasdermin D and release its N-terminal domain triggering pyroptosis.Many studies showed that pyroptosis play a crucial role in hepatic ischemia-reperfusion injury.In this review,we discussed the activation mechanism and research progress of pyroptosis in hepatic ischemia-reperfusion injury.

Shortage of donors is a major obstacle for liver transplantation.Lee innovated dual graft living donor liver transplantation in 2001,obtained graft from two donors,and it was conducted in various parts of the world.At present,South Korea has the biggest numbers in operation,China,Japan,and Germany.Turkey,Romania,and other countries are relatively less;current clinical liver donor liver transplantation is mainly based on single graft living donor liver transplantation,and in some complicated cases,single graft liver transplantation cannot be completed due to various factors,at this situation dual grafts living donor liver transplantation can complete the treatment.Although dual donor liver transplantation can only be carried out in a few areas due to complex surgical procedures,it can enrich the treatment of liver transplantation and promotes the development of liver transplantation.

The anoikis resistance confers the ability of cancer cells to survive and metastasize in the blood circulation without adhesion,but its effect and mechanism in intrahepatic and distant metastasis of hepatocellular carcinoma has not been fully elucidated.Recent studies have shown that certain factors or drugs may inhibit anoikis of hepatoma cells through some signaling pathways.These signaling pathways are not completely separated,they are interconnected to promote metastasis of hepatocellular carcinoma.Liver is the metabolic center of many substances,and many related factors can promote metastasis of hepatocellular carcinoma through inhibiting anoikis.In this review,we summarized the signaling pathways of anoikis resistance of hepatocellular carcinoma.

OBJECTIVE： To investigate and evaluate perioperative medication in elective surgery elderly patients， and to provide reference for perioperative medication management of clinical pharmacists for elderly patients. METHODS： Totally 210 elective surgery elderly patients were selected from Beijing Tsinghua Chang Gung Hospital during Oct. 2015 to Oct. 2016. Pharmacists carried out drug reconstitution， obtained information about their diseases and medication， analyzed and evaluated perioperative medication （indication， usage and dosage， interaction， drug selection， if these drugs should be stopped before surgery） according to Optimal Guidelines for Preoperative Evaluation of Elderly Patients so as to put forward related medication suggestions. RESULTS： Among 210 patients， there were 132 males （62.86％） and 78 females （37.14％） with an average age of （69.96±7.67） years； 43.81％ of patients had more than 3 kinds of diseases， and 13.33％ of patients suffered from more than 5 kinds of diseases； 31.43％ of patients took more than 5 kinds of drug for long term before surgery； 38.10％ patients had more than 2 drug-induced risks； The preoperative medication of 110 patients （52.38％） included drugs that should be avoided before surgery （such as antiplatelet aggregation agents）， 23 patients （10.95％） had potentially inappropriate medication （such as proton pump inhibitors）， 12 patients （5.71％） should use drugs （such as aspirin） cautiously， 35 patients （16.67％） should use drugs （β receptor blocker） continuously during perioperative period. The pharmacists provided 177 times of medication suggestions such as stopping some medications for patients and physicians through medication reconciliation and preoperative medication evaluation （71 times for patients， 106 times for physicians）； the final adoption rates were 100％ and 95.28％， respectively. CONCLUSIONS： The elderly patients have many preoperative complications， various risk factors， multiple medications， so it is vital for their preoperative medication management. The medication reconciliation is an effective way to evaluate preoperative medication in elderly patients， preoperative medication evaluation and analysis in elderly patients is of great significance to ensure the safety of clinical medication.

Endoscopic retrograde cholangiopancreatography (ERCP) is an irreplaceable measure with minimally invasive diagnosis and treatment of endoscopy for biliary and pancreatic diseases, but the related complications associated with ERCP are the highest among the endoscopic procedures. Post-ERCP pancreatitis (PEP) is one of the most common complications with life-threatening in severe cases. Early active prevention can effectively reduce the incidence of post-ERCP pancreatitis. At present, measures including preoperative rectal non-steroidal anti-inflammatory drugs and prophylactic pancreatic stent placement, have definite effective strategy in clinic. Aggressive hydration with lactated Ringer's solution is also a safe and effective way to prevent PEP.

Objective To detect the plasma concentration of tacrolimus and the survival time of rats after small-volume liver transplantation,and to investigate the criteria for immunological rejection after small-volume liver transplantation.Methods Lewis rats and Brown Norway rats were used to establish a small volume and normal liver volume transplantation model,which were divided into 7 groups:whole liver transplantation group (WI),small volume allogeneic liver transplantation group (SI),and whole liver allograft group (WA),small volume allogeneic liver transplantation group (SA),whole liver allograft immunotherapy group (WAT),small volume allogeneic liver transplantation immunotherapy group (SAT),small volume allogeneic liver transplantation immunotherapy modulation group (SATa).Morphological and functional changes of liver tissue were studied postoperatively,AST and tacrolimus plasma concentrations were detected,and survival was recorded.Results Compared with the WA group,the inflammatory cells infiltrated in the portal area of the SA group,the inflammatory changes of the sinusoidal endothelial cells,and the proportion of TCRpositive lymphocytes increased.Four days after transplantation,peripheral blood tests showed that CD4+CD25+ double positive lymphocytes were significantly lower in the allograft group than in the allograft group,and the positive expression rate in the SA group (0.6％) was significantly lower than that in the WA group (1.8％).The differences were statistically significant (P＜0.05).In the SAT group,the blood concentration of tacrolimus was significantly higher than that in the WAT group at each time point (P＜0.05).The blood concentration of tacrolimus in the SATa group was relatively stable,and the plasma concentration of the SATa group was stable.And AST was significantly lower than the SAT group,the differences were statistically significant (P＜0.05).Compared with WAT group,the proliferation and apoptosis rate of hepatocytes in SAT group and SATa group were significantly increased.The proliferation of hepatocytes in SATa group was significantly higher than that in SAT group (P＜0.05).Survival analysis showed that the cumulative survival rate of the WA group was 85.7％,which was significantly higher than that of the SAT group (28.6％).The difference was statistically significant (P＜0.05).The cumulative survival rate of the SATa group was 51.7％.The survival time of WAt group was (57.4±25.0) days,SAT group was (28.0±29.10) days,SATa group was (39.7± 29.0) days,which were longer than untreated groups.The ratio of proliferation to apoptosis (PRA) increased with increasing time of tacrolimus.Regardless of blood concentration,tacrolimus plasma concentration was positively correlated with AST (R =0.758,P＜0.05),indicating RPA was inversely correlated with AST (R=-0.962,P＜0.05).Conclusion The use of tacrolimus significantly prolonged the survival time of small-volume allogeneic liver transplantation rats.Adjusting the amount of tacrolimus under the guidance of tacrolimus plasma concentration and AST serum value equation TD =-0.494TC-0.0035AST+ 260.487 to make the blood concentration relatively stable,it can further extend the allogeneic liver transplantation rat time to live.

Objective: To evaluate the effectiveness and to explore the releated factors of antiretroviral therapy among HIV/AIDS patients in Liangshan Yi Autonomous Prefecture, Sichuan Province. Methods: The method of convenience sampling was adopted in July 2017 to select the research objects who were accepted antiretroviral therapy (ART) over 6 months, older than 18 years and had HIV viral load in 2016, totally 400 cases. A retrospective study was used to collect the data, including social demography, medicine use, information of medical service acquisition, their own behaviors and cognition. 395 questionnaires were effectively recovered. χ² test and logistic regression were performed to examine relationships between factors and effects. Results: All of the 395 respondents were Yi-nationality. The average age of all cases was (39.23±7.52) years old and 223 were male (56.5%). Among 395 cases patients who were detect Viral load in 2016, 221 cases were under the number of 400 copies, thze effective rate of ART was 55.9%. Multivariate analysis showed that HIV/AIDS patients who missed the medication during the antiviral therapy had poor antiviral effects. Compared to those who adhered to medication, the treatment-ineffective OR (95%CI) of the patients missing the medication during the therapy was 7.06 (3.67-13.58); Compared to those who had adverse reactions that affect the therapy, the treatment-ineffective OR (95%CI) of the patients with mild adverse reactions that did not affect the therapy was 0.45 (0.23-0.87); Compared to the patients who used drugs during the treatment, the treatment-ineffective OR (95%CI) value of the antiretroviral therapy effect of non-drug users was 0.39 (0.16-0.91);Compared to the patients who have a correct cognition that insisting on taking medicine correctly can extend their life expectancy as a common person, the treatment-ineffective OR (95%CI) values for those who hold the view that could be prolonged by 10-20 years and not/unknown were 4.18 (1.59-10.99) and 6.64 (2.67-16.53). Conclusion The HIV/AIDS patients who receive ART were less effective in Liangshan, Prefecture. Missings drugs is one of the main influencing factors for the ineffective treatment.
