RESUMEN
Objective:To investigate the prognostic value of baseline peripheral blood inflammatory biomarkers for prognosis in patients with advanced hepatocellular carcinoma (HCC) receiving immunotherapy combined with targeted therapy.Methods:The clinical data of a total of 120 patients with advanced HCC who received immunotherapy combined with targeted therapy at Cancer Center of Renmin Hospital of Wuhan University from December 2019 to March 2022 were analyzed retrospectively. Receiver operating characteristic (ROC) curve was used to calculate the optimal cut-off values of neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), lymphocyte-to-monocyte ratio (LMR), systemic immune inflammation index (SII) and prognostic nutritional index (PNI). According to the optimal cut-off values, the study objects were divided into high value group and low value group. The Kaplan-Meier method was used for survival analysis. Cox proportional hazard regression model was applied to analyze the factors associated with prognosis.Results:By the end of follow-up, 74 patients died and 46 survived. The median follow-up time was 23.0 months, the median overall survival (mOS) was 15.6 months, and the median progression-free survival (mPFS) was 13.1 months. ROC curve analysis showed that the optimal cut-off values of NLR, PLR, SII, LMR and PNI were 3.45, 131.87, 626.21, 2.12 and 43.30, respectively. The mPFS (18.3 months vs. 8.7 months) and mOS (26.6 months vs. 10.9 months) of patients in the low-NLR group ( n=75) were longer than those of the high-NLR group ( n=45), and there were statistically significant differences ( χ2=55.64, P<0.001; χ2=64.14, P<0.001). The mPFS (17.9 months vs. 10.9 months) and mOS (24.5 months vs. 13.5 months) of patients in the low-PLR group ( n=55) were longer than those of the high-PLR group ( n=65), and there were statistically significant differences ( χ2=5.27, P=0.023; χ2=11.84, P<0.001). The mPFS (18.0 months vs. 10.7 months) and mOS (25.7 months vs. 12.8 months) of patients in the low-SII group ( n=75) were longer than those of the high-SII group ( n=45), and there were statistically significant differences ( χ2=24.46, P<0.001; χ2=25.42, P<0.001). The mPFS (18.2 months vs. 10.9 months) and mOS (26.6 months vs. 13.2 months) of patients in the high-LMR group ( n=56) were longer than those of the low-LMR group ( n=64), and there were statistically significant differences ( χ2=19.25, P<0.001; χ2=19.92, P<0.001). The mPFS (17.9 months vs. 10.9 months) and mOS (25.4 months vs. 13.4 months) of patients in the high-PNI group ( n=62) were longer than those of the low-PNI group ( n=58), and there were statistically significant differences ( χ2=13.69, P<0.001; χ2=19.07, P<0.001). Univariate analysis showed that Barcelona clinic liver cancer (BCLC) stage ( HR=1.83, 95% CI: 1.17-2.87, P=0.008), Child-Pugh grade ( HR=2.21, 95% CI: 1.47-3.34, P<0.001), modified albumin-bilirubin (mALBI) grade ( HR=1.35, 95% CI: 1.01-1.81, P=0.045), extrahepatic metastases ( HR=2.18, 95% CI: 1.47-3.25, P<0.001), NLR ( HR=1.40, 95% CI: 1.28-1.54, P<0.001), PLR ( HR=1.00, 95% CI: 1.00-1.01, P=0.001), SII ( HR=1.00, 95% CI: 1.00-1.00, P<0.001), LMR ( HR=0.64, 95% CI: 0.51-0.79, P<0.001) and PNI ( HR=0.95, 95% CI: 0.93-0.98, P=0.001) were correlated with PFS; BCLC stage ( HR=2.18, 95% CI: 1.21-3.91, P=0.009), Child-Pugh grade ( HR=2.57, 95% CI: 1.61-4.09, P<0.001), Eastern Cooperative Oncology Group performance status score ( HR=1.59, 95% CI: 1.01-2.51, P=0.044), mALBI grade ( HR=1.60, 95% CI: 1.17-2.17, P=0.003), extrahepatic metastasis ( HR=2.51, 95% CI: 1.59-3.96, P<0.001), NLR ( HR=1.45, 95% CI: 1.32-1.60, P<0.001), PLR ( HR=1.01, 95% CI: 1.01-1.01, P<0.001), SII ( HR=1.01, 95% CI: 1.01-1.01, P<0.001), LMR ( HR=0.57, 95% CI: 0.40-0.72, P<0.001) and PNI ( HR=0.92, 95% CI: 0.89-0.96, P<0.001) were correlated with OS. Multivariate analysis showed that extrahepatic metastasis ( HR=1.78, 95% CI: 1.10-2.87, P=0.018) and NLR ( HR=1.46, 95% CI: 1.24-1.73, P<0.001) were independent influencing factors for PFS; extrahepatic metastasis ( HR=2.09, 95% CI: 1.21-3.61, P=0.009), NLR ( HR=1.56, 95% CI: 1.29-1.88, P<0.001), SII ( HR=1.00, 95% CI: 1.00-1.00, P=0.025), LMR ( HR=0.59, 95% CI: 0.45-0.78, P=0.008) and PNI ( HR=0.93, 95% CI: 0.88-0.99, P=0.013) were independent influencing factors for OS. Conclusion:NLR and extrahepatic metastasis can be regarded as important indicators to predict PFS in patients with advanced HCC receiving immunotherapy combined with targeted therapy, and NLR, SII, LMR, PNI and extrahepatic metastasis can be regarded as important indicators to predict OS in patients with advanced HCC receiving immunotherapy combined with targeted therapy. High NLR, high SII, low LMR, low PNI and extrahepatic metastasis indicate poor prognosis of HCC patients.

Problem based learning(PBL) is a teaching mode which is based on the autonomous learning of students in small groups.Due to the limited conditions,PBL method can not be widely applied in Guangzhou Medical University.Teaching and research section of pharmacology established a web based PBL teaching mode (W-PBL) in the school through Blackboard net platform,which enlarged the teaching scope and provided students and teachers with a teaching mode having updated learning patterns and high efficiency.Results of this practice were satisfactory and teaching effect was improved significantly.
RESUMEN
Objective To study the optimum combination of orientation parameter of total hip prosthesis and acetabular safe zone on condition that the range of motion for activities of daily living (ADL) is fulfilled.Methods A three-dimensional generic parametric and visually kinematic simulation module of THA was developed.Range of motion ( ROM ) of hip flexion ≥ 110°,internal-rotation ≥30° at 90° flexion,extension ≥30° and external rotation ≥40° were defined as the normal criteria for ADL.ROM of hip flexion ≥ 120°,internal-rotation ≥45° at 90° flexion,extension ≥30° and external rotation ≥40° were as the severe criteria.The ranges of changes in general ratios (GRs) of head-neck,femoral neck antevemion ( FNA ),operative inclination (OI) and anteversion (OA) of acetabulur components were 2.0-2.92,0°-30°,10°-60°,and 0°-70° respectively.Within the limits of the upper two activity criteria,the synchronous OA of acetabulur components was calculated with every 5°change in OI of the cup,and the collodiaphyseal angle ( CDD ) was set as 135°.The safe-zone of combination of acetabulur operative anteversion (OA) and inclination (OI) was defined as the area that fulfilled the two mentioned criteria of ROM without cup-neck impingement.All parameters were analyzed by using SAS 6.12 software.Results The safe zone of acetabdar angle rose with the increase of GRs of head-neck and the safe zone of severe criteria was smaller than that of normal criteria.When the CDD angle was 135°,the sum of average aeetabular OA and acetahular OI plus 0.816 times of the FNA equaled to 84.76° innormal criteria; and the sum of average acetabular OA and acetabular OI plus 0.873 times of the FNA equaled to 92.04° in severe criteria.Conclusions A high GR of head-neck greatly increases the size of safe-zone of acetabular angle.The higher demand of ROM of hip joint requires the smaller safe zone of acetabular angle,as can be corrected by increasing the GR of head-neck.The optimum combination between the sum of average acetabular OA and acetabular OI ( Y) plus FA (X)in the normal criteria and severe criteria can be estimated by using the following formulae:Y1 =-0.816X1 + 84.76 (R2 =0.993 ),Y2 =-0.873X2 + 92.04( R2 =0.999) respectively.
RESUMEN
For non-invasive blood glucose detection through near-infrared spectroscopy, it is very important to ensure the data quantity and reliability of calibration model. In this paper, the method of sampling blood by tubing pump in OGTT (Oral Glucose Tolerance Test) is used to get reliable and adequate reference data of blood glucose concentration for calibration model, and the non-invasive blood detection system based on the AOTF (Acousto-Optic Tunable Filter) ranging from 1100 nm to 1700 nm is designed. 3 experiments were performed by the above system and method. The results showed that based on the PLS (Partial Least Square) calibration models constructed by analyzing all individual experimental data, the correlation coefficients were 0.986, 0.971 and 0.985, respectively, and the RMSEP (Root Mean Square Error of Prediction) estimated by Full Cross Validation were 0.550 mmol/l, 0.456 mmol/l and 0.520 mmol/l; respectively. The results also showed that the prediction error of the model decreased when the number of effective model data increased.

Objective To explore the etiology of and timing for operation of acalculous biliary acute pancreatitis(ABAP).MethodsWe retrospectively analyzed the etiology study and treatment experience of 38 cases of ABAP.ResultsThirteen cases underwent a surgery, including 6 early operations for complicated biliary tract infection without morbidity and mortality, 5 middle staged patients (5～14 days after onset of ABAP) underwent surgery because of intraabdominal indications with one postoperative death and 2 late operations for severe acute pancreatitis (SAP) resulted in one postoperative death of sepsis. The total postoperative mortality rate was 15%( 2/13). Four SAP cases were managed conservatively with one death of MOF. The remaining 21 cases of acute edematous pancreatitis (AEP) were cured by nonoperative methods.ConclusionWhereas an early exploration is indicated, when complicated by biliary tract infections, it is judicious to try a conservative therapy first for ABAP patients.
