Objective To determine the perioperative risks of partial hepatectomy by determining the preoperative liver functional reserve in patients with hepatocellular carcinoma (HCC),and to compare the model for end-stage liver disease (MELD) score with the Child-Pugh classification in predicting prognosis.Methods We reviewed the clinical data of 202 patients with HCC who underwent partial hepatectomy.The MELD score and the Child-Pugh classification were determined preoperatively.Results The incidence of postoperative liver dysfunction happened in 44.0% of Child A patients,50% in Child B patients,41.6%in patients with a MELD score below 14,and 91.7% in patients with a MELD score of > 14.The difference between the rates of postoperative liver dysfunction in patients with a preoperative MELD score above 14 and below 14 was significant (P < 0.05),while that between patients with Child-Pugh A and B was insignificant (P > 0.05).The incidences of postoperative liver dysfunction in patient with a MELD < 8,8 ≤ MELD ≤ 14,MELD > 14 were 38.2%,57.6% and 91.7%,respectively,indicating that there was a positive co-relationship between the MELD score and the incidences of liver dysfunction.The Spearman rank correlation test showed the MELD score was significant correlated with the Child-Pugh score (r =0.404 ; P < 0.05).The areas under the ROC curves of the MELD score and the Child-Pugh score were 0.703 and 0.587 (P < 0.05).Conclusions The MELD score predicted postoperative liver dysfunction more accurately than the Child-Pugh classification.HCC patients undergoing partial hepatectomy with a preoperative MELD score > 14 had a high perioperative risk.To ensure the safety of partial hepatectomy,HCC patients with a preoperative MELD score > 14 requires active preoperative preparation,bringing the score near to or less than 14.

BACKGROUNDMagnetic anchored surgical instruments (MASI), relying on magnetic force, can break through the limitations of the single port approach in dexterity. Individual characteristic abdominal wall thickness (ICAWT) deeply influences magnetic force that determines the safety of MASI. The purpose of this study was to research the abdominal wall characteristics in MASI applied environment to find ICAWT, and then construct an artful method to predict ICAWT, resulting in better safety and feasibility for MASI.
METHODSFor MASI, ICAWT is referred to the thickness of thickest point in the applied environment. We determined ICAWT through finding the thickest point in computed tomography scans. We also investigated the traits of abdominal wall thickness to discover the factor that can be used to predict ICAWT.
RESULTSAbdominal wall at C point in the middle third lumbar vertebra plane (L3) is the thickest during chosen points. Fat layer thickness plays a more important role in abdominal wall thickness than muscle layer thickness. "BMI-ICAWT" curve was obtained based on abdominal wall thickness of C point in L3 plane, and the expression was as follow: f(x) = P1 × x 2 + P2 × x + P3, where P1 = 0.03916 (0.01776, 0.06056), P2 = 1.098 (0.03197, 2.164), P3 = -18.52 (-31.64, -5.412), R-square: 0.99.
CONCLUSIONSAbdominal wall thickness of C point at L3 could be regarded as ICAWT. BMI could be a reliable predictor of ICAWT. In the light of "BMI-ICAWT" curve, we may conveniently predict ICAWT by BMI, resulting a better safety and feasibility for MASI.

Endometrial receptivity refers to the ability of endometrium to accept and accommodate endometrial implantation in the process of embryo implantation in implantation window period. It is an important factor affecting the rate of blastocyst implantation in assisted reproduction. It is worth mentioning that ovulation-promoting drugs in current assisted reproduction technology could reduce endometrial receptivity and inhibit blastocyst implantation, greatly affecting the success rate of assisted reproduction. By searching Chinese Scientific Citation Database, it was found that 121 studies from 2006 to 2017 showed that Chinese Bushen Huoxue prescriptions could significantly improve the development of pinopodes in the implantation window, promote the expression of endometrial receptors ER, PR, integrinβ3, LIF, LPA3 and other molecules, and thus enhancing endometrial receptivity and improving embryo implantation. In the theory of traditional Chinese medicine, kidney deficiency is an important factor causing infertility. Chinese Bushen Huoxue prescriptions could nourish the kidney-essence, and promote blood circulation, playing an important role in treating infertility with combined application of western medicine and traditional Chinese medicine. These studies suggest that Chinese Bushen Huoxue prescriptions could improve endometrial receptivity, and their mechanisms are worth further investigation. This article has summarized the research progress of Chinese Bushen Huoxue prescriptions in the field of assisted reproduction, summarized the deficiency of current researches, and preliminarily discussed the potential application prospect of Chinese Bushen Huoxue prescriptions in the treatment of infertility.

Objective To evaluate the clinical efficacy of endoscopic retrograde cholangiopancreatography (ERCP)-based comprehensive minimally invasive treatment for biliary anastomotic stenosis (BAS) after liver transplantation. Methods Clinical data of 60 BAS recipients after liver transplantation were retrospectively analyzed, 54 male and 6 female, aged (48±10) years. ERCP was initially carried out. If it succeeded, plastic or metallic stents were placed into the biliary tract. If it failed, percutaneous transhepatic cholangial drainage (PTCD) or single-operator cholangioscopy (SpyGlass) was adopted to pass through the stenosis. If all these procedures failed, magnetic anastomosis or other special methods were delivered. The incidence and treatment of BAS after liver transplantation were summarized. The efficacy, stent removal and recurrence were observed. Results The median time of incidence of BAS after liver transplantation was 8 (4, 13) months. Within postoperative 1 year, 1-2 years and over 2 years, 39, 16 and 5 recipients were diagnosed with BAS, respectively. All 60 BAS recipients after liver transplantation were successfully treated, including 56 cases initially receiving ERCP, and 41 completing BAS treatment, with a success rate of 73%. The failure of guide wire was the main cause of ERCP failure. The success rates of PTCD, SpyGlass and magnetic anastomosis were 5/9, 5/7 and 7/8, respectively. Two recipients were successfully treated by percutaneous choledochoscope-assisted blunt guide wire technique and stent placement in the biliary and duodenal fistula. After 3 (3, 4) cycles of ERCP and 13 (8, 18) months of stent indwelling, 38 recipients reached the stent removal criteria, including 25 plastic stents and 13 metallic stents. The indwelling time of plastic stents was longer than that of metallic stents (

Objective:To investigate the clinical efficacy of 3D printed guide plate-assisted hematoma puncture and catheter drainage in the treatment of a moderate volume of hypertensive intracerebral hemorrhage in the basal ganglia.Methods:The clinical data of 42 patients with a moderate volume of hypertensive intracerebral hemorrhage in the basal ganglia who received treatment with 3D printed guide plate-assisted hematoma puncture and catheter drainage in Dazhu Hospital of North Sichuan Medical College from January 2016 to January 2021 were retrospectively analyzed. In the traditional puncture group, there were 19 patients who received traditional punctures according to preoperative cranial CT findings (traditional puncture group). In the 3D printed guide plate puncture group, there were 23 patients who received hematoma puncture and catheter drainage assisted by a 3D printed guide plate. Preoperative preparation time (from admission to operation), operative time, the number of hematoma punctures, hematoma clearance rate, postoperative indwelling time of drainage tube, residual hematoma rate, the occurrence of puncture canal bleeding, intracranial infection, Glasgow Coma Scale score measured at 3 and 7 days after surgery, and Glasgow Outcome Scale score measured at 1, 3 and 6 months after surgery were compared between the two groups.Results:There were no significant differences in preoperative preparation time and operative time between the two groups ( t = 0.25, 0.40, both P > 0.05). 3D-printed guide plate-assisted hematoma puncture reduced the probability of reveiving one more hematoma puncture during the surgery. There was no significant difference in the number of hematoma puncture between the two groups ( χ2= 0.48, P > 0.05). There were no significant differences in the probabilities of puncture canal bleeding and intracranial infection between the two groups ( χ2 = 0.05, 0.03, both P > 0.05). Postoperative indwelling time of the drainage tube in the 3D printed guide plate puncture group was significantly shorter than that in the traditional puncture group [(3.10 ± 0.38) vs. (3.46 ± 0.52) days, t = 2.65, P < 0.05]. The residual hematoma rate in the 3D printed guide plate puncture group was significantly lower than that in the traditional puncture group [(32.04 ± 5.33)% vs. (37.37 ± 5.51)%, χ2 = 3.20, P < 0.05]. There were significant differences in Glasgow Coma Scale score measured at 3 and 7 days after surgery between the two groups [(12.04 ± 1.19) points vs. (11.26 ± 0.93) points, (13.65 ± 0.88) points vs. (12.94 ± 0.97) points, t = 2.33, 2.46, both P < 0.05]. Glasgow Outcome Scale score measured at 1, 3, and 6 months after surgery in the 3D printed guide plate puncture group was 18, 21, and 22 points, respectively, which was significantly higher than 9, 11, and 12 points in the traditional puncture group ( χ2 = 4.34, 4.69, 5.17, all P < 0.05). Conclusion:3D printed guide plate assisted hematoma puncture and catheter drainage for treatment of a moderate volume of hypertensive intracerebral hemorrhage in the basal ganglia can increase the accuracy of puncture, decrease hematoma residual rate, improve short- and long-term prognosis, does not prolong preoperative preparation time. Moreover, it costs low, is safe, and is easy to learn.

Objective:To study on the association between vasoactive-inotropic score(VIS) and mortality of total arch replacement in Stanford type A aortic dissection(TAAD) patients.Methods:Data of TAAD patients admitted from January 2018 to November 2018 were analyzed retrospectively. According to the inclusion and exclusion criteria, 187 patients were finally included in the analysis. 30-day mortality was calculated and the patients were divided into death group(18 cases) and non-death group(169 cases). The VIS at each time point and perioperative indexes of the two groups were compared. The value of VIS in predicting mortality was analyzed.Results:The 30-day mortality was 9.63%(18/187). The operation time, cardiopulmonary bypass time, ventilator assistance time, the incidence of tracheotomy and major postoperative complications in the death group were significantly higher than those in the non-death group( P<0.05). VIS of death group was significantly higher than that of non-death group( P<0.05). At each time point, the area under ROC curve(AUC) of VIS was greater than 0.500( P<0.05), among which AUC of ICU 48 h VIS was the largest(0.817), and the best cut-off point of ICU 48 h VIS was determined to be 9, sensitivity 61.1%, specificity 92.3%. Logistic regression analysis showed that ICU 48 h VIS was an independent risk factor for predicting the death of total arch replacement in TAAD patients( OR=1.465, 95% CI: 1.194-1.796, P<0.001). Conclusion:When ICU 48 h VIS≥9, the risk of death was increased in patients with total arch replacement of TAAD. VIS may be a useful reference index for predicting the mortality of total arch replacement in TAAD patients in the early postoperative period.
