Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) could induce extensive and rapid future liver remnant hypertrophy. However, the morbidity for ALPPS is very high. This paper reports a modified ALPPS (associating microwave ablation and portal vein ligation for staged hepatectomy, AMAPS), which was successfully applied in the treatment of huge hepatocellular carcinoma with cirrhosis, and the procedure of operation was greatly simplified. Hence, AMAPS is feasible and safe in selected patients with primary hepatocellular carcinoma and cirrhosis.

Objective:To analyze the relationship between systemic immune-inflammatory index (SII) and clinical characteristics of pancreatic cancer patients and the factors influencing SII.Methods:To retrospectively analyze the data of 98 pancreatic cancer patients with R 0 resection in the Department of Hepatobiliary Surgery, Affiliated Hospital of Guizhou Medical University, from January 2018 to January 2023, of whom 54 were male and 44 were female at the age of (59.2±10.7) years. All patients were divided into the high SII group ( n=49) and the low SII group ( n=49) based on the median SII of 668. Preoperative albumin, proportion of tumor located in the head of the pancreas, preoperative total bilirubin, and length of hospitalization were compared between the two groups. The correlation between SII and clinical features was analyzed. The SII influencing factors of pancreatic cancer patients were analyzed by linear regression with univariate and multivariate analysis. Results:The preoperative albumin of pancreatic cancer patients in the high SII group was lower than that of the low SII group, while the proportion of tumors located in the head of the pancreas, the preoperative total bilirubin, and the length of hospital stay were higher than that of the low SII group, and the differences were all statistically significant (all P<0.05). Correlation analysis showed a negative correlation between preoperative albumin and SII ( r=-0.28, P=0.050), while a positive correlation between preoperative total bilirubin and SII ( r=0.36, P<0.001), as well as between hospitalization time and SII ( r=0.28, P=0.050). The SII of patients with tumors located in the head of the pancreas ( n=81) and the tail of the pancreatic body ( n=17) were 734 (418, 1 241) and 431 (276, 613), respectively, and the SII of patients who survived ( n=92) and died ( n=4) at the time of discharge were 628 (383, 1 113) and 1 283 (1 176, 1 507), respectively, and the differences in SII of patients with different tumor locations and different discharge status were all significant. The SII of the patients were compared, and the differences were statistically significant ( Z=-2.51, 2.05, P=0.012, 0.038). Screening variables in the univariate linear regression model showed that admission total bilirubin, tumor volume, and preoperative albumin were associated with SII levels (all P<0.05). When the above variables were included in the multivariate linear regression, the higher the preoperative total bilirubin ( β=2.74, 95% CI: 1.48-4.00, P<0.001) as well as the larger the tumor volume ( β=2.34, 95% CI: 1.04-3.63, P<0.001) in pancreatic cancer patients, the higher the value of SII. Conclusions:SII in pancreatic cancer patients was associated with preoperative albumin, tumor location, preoperative total bilirubin, length of hospital stay, and survival or death at discharge. Preoperative total bilirubin and tumor volume were influential factors of SII in patients with pancreatic cancer.

OBJECTIVETo study the relationship between polymorphisms of interleukin 10 (IL10QX) promoter and serum levels of lipoprotein in the healthy Chinese Han population.
METHODSPCR restriction fragment length polymorphism assay was used to detect the distribution of genotypes of IL10 -592,-819,-1082 in 200 healthy Chinese Han subjects. Serum levels of total cholesterol (TC), triglyceride (TG), high density lipoprotein-cholesterol (HDL-C), low density lipoprotein-cholesterol (LDL-C) and very low-density lipoprotein (VLDL) in all subjects were measured to analyze the relationship with the polymorphisms of IL10 promoter.
RESULTSComparing with AA genotype, the group with GA genotype at IL10 promoter -1082 position had a significant elevation of serum HDL-C level [(1.514+/-0.501) mmol/L vs. (1.261+/-0.346) mmol/L, t=-2.225, P=0.028] and a lower serum TG level[(1.701+/-1.836) mmol/L vs. (0.981+/-0.314) mmol/L,Z=-2.096,P=0.036]. The TG, TC, HDL-C, LDL-C and VLDL levels did not show any statistically significant differences among different genotypes (CC, AA, CA) of the IL10 -592, as well as the genotypes (TT, TA, AA) ofIL10 -819 (P>0.05).
CONCLUSIONThe results suggest that in the Chinese Han population, the polymorphism at position -1082 in the promoter region of IL10 gene may be associated with the serum HDL-C level and TG level.

The aim of this study was to investigate effects of IAT and MAT chemotherapeutic regimens treating patients with refractory and relapsed acute myeloid leukemia (AML). 99 patients with refractory and relapsed AML received IAT regimen or MAT regimen as study objects were retrospectively analyzed (56 patients with refractory AML and 43 patients with relapsed AML). Among of them, 28 patients were treated with IAT regimen, and 71 patients received with MAT regimen. The results showed that in 2 groups mentioned above the OR was 65.7%, CR was 49.5%, PR was 16.2%; in IAT group the OR was 64.3%, CR was 46.4%; in MAT group the OR was 66.2%, CR was 50.7%, no statistical difference was found between these 2 groups; The 2 years overall survival was 25% in IAT group and 15.5% in MAT group. Serious infection in IAT and MAT regime groups was 25% and 9.9%, respectively. It is concluded that both IAT and MAT regimens are effective methods for inducing CR in patients with refractory of relapsed AML. IAT and MAT regimens can be used in treatment of the refractory or relapsed MAL patients who were not respond to other regimen.

Objective To explore the epidemiological status of abnormal glucose metabolism and its influential factors among middle and aged population with hypertension in Chengdu area. Methods In 2008, after adopting the methods of stratified cluster sampling, the authors investigated 4685 subjects of the middle and aged population between the age of 40-79 in Chengdu urban and rural area by checking blood pressure and oral glucose tolerance test (OGTY). Patients with previously known diabetes mellitus (DM) were only asked to perform fasting glucose and to carry out a questionnaire. Comparison of the prevalence rates of abnormal glucose metabolism in hypertensive and non-hypertensive subjects was carried out. The prevalence rates of isolated impaired glucose tolerance (I-IGT) and isolated postprandial hyperglycemia (IPH) among middle and aged subjects with hypertension were acquired and the influential factors of abnormal glucose metabolism among middle and aged subjects with hypertension were analyzed. Results The prevalence rate of abnormal glucose metabolism in the hypertensive subjects was obviously higher than that in the non-hypertensive subjects; without using OGTT, 72.9% of the pre-diubetic and 54. 4% of the new diagnosed DM patients would remain undiagnosed if fasting plasma glucose detection was used alone. Age, diabetic history of first degree relatives ,overweight or obesity were the risk factors for the development of abnormal glucose metabolism among middle and aged male subjects with hypertension in Chengdu area. Exercise training and high education level were the protective factors. Age, diabetic history of first degree relatives,abdominal obesity and hypertriglyceridemia were the risk factors for the development of abnormal glucose metabolism among middle and aged female subjects with hypertension in Chengdu area. Conclusions More than 50% of middle and aged subjects with hypertension in Chengdu area has accompanying abnormal glucose metabolism. OGTT easily discloses the abnormal status and should be a routine procedure in the diagnosis of pre-diabetes or DM in such population. Appropriate exercise, learning diabetes-related knowledge to take reasonable lifestyle, and intervention of metabolic factors such as overweight or obesity are advised. Abdominal obesity and hypertriglyceridemia play important roles in leading to abnormal glucose metabolism among middle and aged population with hypertension.

BACKGROUNDThe treatment for long bone defects has been a hot topic in the field of regenerative medicine. This study aimed to evaluate the therapeutic effects of calcium sulfate (CS) combined with platelet-rich plasma (PRP) on long bone defect restoration.
METHODSA radial bone defect model was constructed through an osteotomy using New Zealand rabbits. The rabbits were randomly divided into four groups (n = 10 in each group): a CS combined with PRP (CS-PRP) group, a CS group, a PRP group, and a positive (recombinant human bone morphogenetic protein-2) control group. PRP was prepared from autologous blood using a two-step centrifugation process. CS-PRP was obtained by mixing hemihydrate CS with PRP. Radiographs and histologic micrographs were generated. The percentage of bone regenerated bone area in each rabbit was calculated at 10 weeks. One-way analysis of variance was performed in this study.
RESULTSThe radiographs and histologic micrographs showed bone restoration in the CS-PRP and positive control groups, while nonunion was observed in the CS and PRP groups. The percentages of bone regenerated bone area in the CS-PRP (84.60 ± 2.87%) and positive control (52.21 ± 4.53%) groups were significantly greater than those in the CS group (12.34 ± 2.17%) and PRP group (16.52 ± 4.22%) (P < 0.001). In addition, the bone strength of CS-PRP group (43.10 ± 4.10%) was significantly greater than that of the CS group (20.10 ± 3.70%) or PRP group (25.10 ± 2.10%) (P < 0.001).
CONCLUSIONCS-PRP functions as an effective treatment for long bone defects through stimulating bone regeneration and enhancing new bone strength.
