Objective:To investigate the relationship of osteoporotic vertebral body compression fracture(OVCF)with multifidus muscle and intervertebral disc degeneration in the lower lumbar spine and the lumbar-pelvic parameters in elderly women.Methods:Clinical data of a total of 108 elderly women with osteoporosis were retrospectively analyzed.They were divided into the fracture group(n=56)and the control group(n=52)according to the presence of vertebral body compression fractures.Age, body mass index(BMI)and bone mineral density(BMD)were collected in two groups.The angle of pelvic incidence(PI), angle of pelvic tilt(PT), low lumbar lordosis(LLL)and sacral slope(SS)were measured by the standing lumbar lateral X-ray photography.The degree of degeneration of intervertebral disc L 3-S 1 and multifidus muscle were detected by using the lumbar MRI.These parameters were compared between the two groups. Results:The age, BMI and BMD had no significant difference between the two groups( P>0.05). The degree of intervertebral disc degeneration of L 3-L 4 and L 4-L 5 was statistically significant higher in the fracture group than in the control group( Z=-4.656 and -2.675, P=0.000 and 0.007), while the degree of intervertebral disc degeneration of L 5-S 1 had no statistically significant difference between the two groups( Z=-1.784, P=0.075). There were statistically significant higher multifidus muscle degeneration of L 3-L 4 and L 4-L 5 in the fracture group than in the control group( Z=-3.248 and -4.073, P=0.001 and 0.000), while no significant difference between the two groups in multifidus muscle degeneration of L 5-S 1( Z=-1.096, P=0.282). No statistically significant differences were found in PI, PT, SS and LLL between the two groups( t=1.162, 0.827, -0.082 and -0.677, P=0.248, 0.410, 0.935 and 0.500). Conclusions:The degeneration of intervertebral disc and multifidus muscle of L 3-L 4 and L 4-L 5 is positively correlated with OVCF in elderly women.

Objective To investigate the protective effect and mechanism of irbesartan and edaravone on the rat liver transplantation model using small-for-size graft during acute phase of reperfusion.MethodsWe used 300 S-D rats for small-for-size graft liver transplantation,and the light rats were used as donors.Survived recipients were divided into five groups according table of random number:group A,control group; group B,edaravone treatment group; group C,irbesartan treatment group; group D,irbesartan and edaravone treatment group; group E,sham operation group.The rat 30% small-for-size graft model was established.Six rats in each group were sacrificed randomly at 6th and 24th h after reperfusion respectively. The survival rate of animals and portal pressure were investigated.The rats in every group were sacrificed and blood samples were collected for liver function measurement.The contents of SOD and MDA in liver tissues were measured.Fresh liver tissue was used to detect the mRNA expression of Egr-1,ET1 and Bax by RT-PCR. Paraffinembedded liver specimens were used to assay apoptosis (TUNEL).Six rats at each time point in each group were studied.Results(1) One-week survival rate in the groups A,B,C,D and E was 8.33%(1/12),33.3% (4/12),58.7% (7/12),83.3% (10/12),and 100% (12/12),respectively,P<0.05; (2) There was significant difference in the portal pressure,ALT,AST,MDA,SOD,Egr-1,ET-1,Bax,and the apoptotic index between treatment groups and control group,especially in the group D,P<0.05 or P<0.01.Conclusion Irbesartan and edaravone could protect small-for-size graft in partial liver transplantation probably by reducing portal vein pressure and diminishing ischemia reperfusion injury.The combined use of Irbesartan and edaravone is more effective than irbesartan or edaravone used alone.

ObjectiveTo investigate the clinical significance of admission hemoglobin (Hb) value for posttransplantation early respiratory complications in cirrhotic hepatocellular carcinoma (HCC) patients undergoing liver transplantation (LT).MethodsBetween April 2001 and February 2010,the medical record of 100 consecutive liver recipients at First Affiliated Hospital of Guangxi Medial University were retrospectively reviewed. Pulmonary complications developed in 45 patients after LT. Using bivariate correlation analysis between the admission Hb value and pulmonary complications screened for the threshold value of admission Hb value affecting early-phase pulmonary complications.According to the threshold value of admission Hb,LT recipients could be divided into two groups. Twenty-seven peri-operative clinical parameters were analyzed in the two groups.ResultsAdmission Hb ≤ 100 g/L was the threshold value affecting postoperative pulmonary complications.The duration of time to initial passage of flatus and the ICU length of stay were significantly prolonged in patients with admission Hb values ≤ 100 g/L,in which poorer arterial blood gas analyses were common. ConclusionsThe admission Hb value of patients with cirrhosisassociated hepatocellular carcinoma affects the early-phase prognosis after LT.

Objective To assess the efficacy of orthotopic liver transplantation (OLT) for hepatocellular carcinoma (HCC) and the effect of recipient selection on postoperative survival. Methods The clinical data of 63 patients with primary HCC receiving OLT in this hospital from June 2000 to February 2007 were retrospectively analyzed. The cumulative survival rate after transplantation was analyzed by the Kaplan-Meier method. Results The 1-, 3- and 5-year cumulative survival rates of the 63 patients were 77.4%, 59.3%, 48. 9%, respectively. The rates in conformation with Milan criteria, UCSF criteria and beyond UCSF criteria were 93.8%, 80.8%, 80.8%; 92.1%, 79.2%,79.2%; 29.2%, 8.3%, 0, respectively. The 1-, 3-, 5-year cumulative recurrent rate of patients meeting Milan criteria, UCSF criteria and beyond UCSF criteria was 6.2%, 15.5%, 19. 2%; 7. 9%,15.9%, 20. 8% ; 70. 8%, 87. 5%, 91.7%, respectively (P<0.01). However, tumor recurrence and survival rates were similar for patients meeting UCSF and Milan criteria (P>0. 05). Conclusion Expansion of OLT criteria is justified for HCC and does not adversely impact the posttransplant prognosis by the UCSF criteria as compared with the Milan criteria.

Objective To investigate the correlation between interleukin-6 (IL-6) and future liver remnant (FLR) growth after associating liver partition and portal vein ligation for staged hepatectomy (ALPPS).Methods The retrospective cross-sectional study was conducted.The clinicopathological data of 15 patients who underwent ALPPS at the First Affiliated Hospital of Guangxi Medical University between March 2017 and May 2018 were collected.Observation indicators:(1) intraoperative situations in the first staged ALPPS and the second staged ALPPS;(2) postoperative situations:① postoperative complications and duration of hospital stay,② results of pathological examination;(3) IL-6 concentration in the peripheral blood before and after operation;(4)follow-up situations.Follow-up using outpatient examination,telephone interview and internet was performed to detect life quality and survival of patients.Imaging examination was done to detect tumor recurrence and metastasis.Follow-up was done up to May 2018.Measurement data with normal distribution or similar normal distribution were represented as (x)±s.Measurement data with skewed distribution were described as M (range).Repeated measures data were analyzed by the repeated measures ANOVA.Correlation comparison was done using Pearson bivariate correlation test.Results (1) Intraoperative situations.① The first staged ALPPS:15 patients had liver parenchymal transection via anterior approach combined with selective hepatic vascular exclusion,without allogenic blood transfusion.The operation time,volume of intraoperative blood loss,FLR at postoperative 16 days,interval time to the second staged ALPPS,growth rate of liver volume,ratio of FLR and standard liver volume (SLV) were respectively 324 minutes (range,240-387 minutes),356 mL (range,200-600 mL),(582± 134) cm3,24 days (range,9-34 days),35%±20% and 53%±7%.② The second staged ALPPS:of 15 patients,13 underwent the second staged ALPPS successfully including 11 undergoing middle hepatic vein preserved right hepatectomy and 2 undergoing expanded right hemihepatectomy or right trisegmentectomy,1 underwent transcatheter arterial chemoembolization (TACE) due to FLR/SLV =31%,1 was detected yellow-white nodules at left lobe and confirmed as hepatocellular carcinoma by frozen section pathological examination,and then improved and discharged after 5-FU abdominal local chemotherapy combined with postoperative TACE.The operation time,volume of intraoperative blood loss of 13 patients undergoing the second staged ALPPS were 324 minutes (range,140-515 minutes) and 639 mL(range,100-1 400 mL).Two patients had blood transfusion including 1 with 800 mL of fresh frozen plasma and 4.0 U of red cells and 1 with 600 mL of plasma and 9.5 U of de-leucocytes and red cells.(2) Postoperative situations.① Postoperative complications and duration of hospital stay:15 patients had no perioperative death,9 and 6 were detected grade A and grade B liver failure respectively,15 had grade Ⅰ complications of Clavien-Dindo classification and no patient had grade Ⅱ and above complications,10 had pleural effusion including 1 with volume of effusion >500 mL.Of 13 patients undergoing the second staged ALPPS,4 and 9 were detected grade A and grade B liver failure respectively,8 and 5 had grade Ⅰ and Ⅱ complications of Clavien-Dindo classification and no patient had grade Ⅲ and above complications,11 had few pleural effusion with volume of effusion <500 mL.Patients with grade B liver failure and grade Ⅱ complications were recovered and discharged after treatments of liver protection,gastric protection,reinforced dressing change,continuous use of Alb,fresh frozen plasma transfusion.The patient with volume of pleural effusion > 500 mL was improved after closed thoracic drainage and other patients with pleural effusion were improved after symptomatic and supportive treatment.Duration of total hospital stay was 31 days (range,22-49 days) in 15 patients.② Results of pathological examination:13 patients undergoing complete ALPPS were diagnosed as hepaticocellular carcinoma with R0 resection and without cancer cells involving surgical margin,including 7 with grade Ⅱ portal vein tumor thrombus.Ishak score for postoperative pathological fibrosis and liver cirrhosis was 7.7±1.4 in 15 patients,including 1 case of 5,1 case of 6,2 case of 7,6 case of 8,5 case of 9.(3) IL-6 concentration in the peripheral blood before and after operation:IL-6 concentration in the peripheral blood before surgery was (8±3)ng/L in 15 patients,and (207±150)ng/L,(104±65)ng/L,(45±38)ng/L,(26±9)ng/L,(18±10)ng/L at 1,3,5,7,10 days after the first staged ALPPS,showing a statistically significant difference in changing trend before and after surgery (F=25.877,P<0.05) and statistically significant differences in paired comparison between 1,3,5,7,10 days after the first staged ALPPS and before surgery respectively (P<0.05).There was correlation between IL-6 concentration in the peripheral blood at 1,3 days after the first staged ALPPS and growth of FLR (r=0.766,0.881,P<0.05),and also between IL-6 concentration in the peripheral blood at 1,3 days after the first staged ALPPS and growth rate of FLR (r =0.810,0.879,P< 0.05).(4) Follow-up:15 patients were followed up for 1-14 months with a median time of 7 months.Of the 15 patients,1 without the second staged ALPPS died of multiple organ dysfunction syndrome at 7 months after the first staged ALPPS,14 survived and took care of theirselves in daily life during follow-up with improved life quality,including 1 detected multiple lung metastases at 12 months after complete ALPPS with mild increased AFP and 13 undetected new lesions in the remnant liver on contrast-enhanced CT and liver contrast-enhanced ultrasonography with normal AFP.Conclusion The peak of IL-6 concentration in peripheral blood at 1,3 days after the first staged ALPPS is significantly correlated with the hyperplasia of FLR,which may be used to predict the hyperplasia of FLR.

Background::Sentinel lymph node (SLN) biopsy is gradually accepted as the standard of care in breast cancer patients with down-staged axillary disease after neoadjuvant chemotherapy (NAC). However, it is still difficult to precisely define pre-NAC clinical node-positive (cN1) and post-NAC clinical node-negative (ycN0). This prospective single-center trial was designed to evaluate the feasibility and accuracy of standard targeted axillary dissection (TAD) after NAC in highly selective pre-NAC cN1 patients (not considering ultrasound-based axillary ycN staging).Methods::This prospective trial included patients with initial pre-NAC cT1–3N1M0 invasive breast cancer but with a rigorous definition of cN1 from the Affiliated Cancer Hospital of Zhengzhou University. When NAC was effective (including complete and partial responses) and preoperative axillary palpation was negative, preoperative ultrasound-based axillary staging was not considered, and all patients underwent TAD followed by axillary lymph node (LN) dissection. The detection rate (DR) and false-negative rate (FNR) of TAD were calculated.Results::A total of 82 patients were included, and 77 of them were eligible for data analysis. The DR for TAD was 94.8% (73/77). There were 26 patients with one abnormal LN at the time of diagnosis based on ultrasound, 45 patients with two, and 2 patients with three. One patient had one TAD LN, four patients had two TAD LNs, and 68 patients had three or more TAD LNs. Preoperative axillary palpation yielded negative results for all 73 patients who successfully underwent TAD. Preoperative ultrasound-based ycN0 and ycN+ conditions were detected for 52 and 21 cases, respectively. The FNR was 7.4% (2/27) for standard TAD (≥3 SLNs), which was lower than that of all successful TAD (≥1 SLN; 10.0%, 3/30).Conclusions::In rigorously defined pre-NAC cN1 breast cancer patients, standard TAD is feasible for those with negative axillary palpation after NAC, and FNR is also less than 10%.Registration::chictr.org.cn, ChiCTR2100049093
