Comprehensive treatment dominated by surgery is the mainstay in the treatment of hepatic cancer,and hepatectomy is still the most effective treatment method.Bile duct reconstruction after hepatectomy is still the difficult point for the treatment of hepatic cancer complicated by bile duct invasion.A 45-year-old patient with hepatic cancer and gallstone was admitted to the Affiliated Hospital of Guiyang Medical College,magnetic resonance cholangiopancreatography and enhanced computed tomography indicated that intrahepatic duct was dilated and tumor had invaded both left and right hepatic ducts.Cholecystectomy,mesohepatectomy,duct to duct anastomosis of left hepatic duct and common hepatic duct,duct to duct anastomosis of right hepatic duct and cystic duct were performed during the operation.The patient was cured 2 weeks after surgery.

Objective:To optimize the best molding process of Jinpuju Qingrelishi Granules.Methods:Based on the single factor test, the relative density of clear ointment and the amount of diluent (dextrin∶lactose=2∶1) are used as investigating factors, and the overall evaluation of the molding rate and angle of repose overall desirability (OD) is used as the evaluation index. The effect surface method is used to optimize the best molding process of Jinpuju Qingrelishi Granules.Results:The best molding process conditions: the relative density of the clear paste is 1.20 (60 ℃) and the amount of diluent is 3 times that of the clear paste. After mixing the clear paste and diluent, make soft material, pass through a 14-mesh sieve to granulate, dry in an oven (55 ℃) for 1 hour, and sizing to obtain. The molding rates of the three batches of verification test granules were 93.73%, 93.03%, 95.59%, respectively, the predicted OD value was 0.928, the verification value was 0.936, and the deviation from the predicted value was -0.86%.Conclusion:The molding process of this experiment is stable and reliable, with good repeatability, which can provide a reference for the follow-up research of Jinpuju Qingrelishi Granules.
3.Association between the ratio of dietary vitamin A to body weight and hypertension in children
Chinese Journal of School Health 2024;45(2):267-272
Objective:
To explore the relationship between the ratio of dietary vitamin A (VitA) to body weight and hypertension among children, so as to provide a reference for blood pressure control through dietary nutritional interventions and childhood hypertension prevention.
Methods:
Utilizing the baseline survey and followup sample data from the Healthy Children Cohort established in urban and rural areas of Chongqing from 2014 to 2019, structured quantitative dietary questionnaire and selfdesigned questionnaire were used to investigate the information of dietary intake and socioeconomic characteristics of 15 279 children, as well as blood pressure, height, weight measurement. The ratio of dietary VitA to body weight was divided into four groups based on quartiles [≤P25(Q1), >P25~P50(Q2), >P50~P75(Q3), >P75(Q4)]. Generalized linear regression models and Logistic regression models were used to analyze the correlation between ratio of dietary VitA to body weight with blood pressure levels and prevalence of hypertension.
Results:
The results of the 2014 baseline survey indicated that, after adjusting for confounding factors such as demographic indicators and nutritional intake, significant differences were observed in systolic blood pressure (SBP), diastolic blood pressure (DBP), and mean arterial pressure (MAP) among different groups categorized by the ratio of dietary VitA to body weight (F=157.57, 44.71, 95.92, P<0.01). The baseline ratio of dietary VitA to body weight in children exhibited a negative correlation with DBP, SBP and MAP at baseline and in 2019[baseline: β(95%CI)=-0.65(-0.89--0.42), -0.22(-0.42--0.01), -0.36(-0.56--0.16); 2019: β(95%CI)=-0.77(-1.34--0.19), -0.62(-1.21--0.02), -0.77(-1.34--0.19), P<0.05]. Compared to Q1 group, the risk of hypertension decreased among children in Q4 at baseline and followup in 2019 [OR(95%CI)=0.63(0.49-0.81), 0.18(0.08-0.42), P<0.01].
Conclusions
The ratio of dietary VitA to body weight is significantly negatively correlated with blood pressure levels among children, and dietary VitA deficiency is an independent risk factor for hypertension among children. Measures should be taken to actively adjust childrens dietary nutrition and reduce the risk of childhood hypertension.

Objective:To study the multi-locus sequence typing (MLST) gene characteristics of Brucella isolates in Guizhou Province. Methods:Brucella strains, which were isolated from 2017 to 2021 in Guizhou Province (preserved in the Bacterial and Viral Seed Bank of Guizhou Center for Disease Control and Prevention) were identified Brucella and species/types by BCSP31-PCR and AMOS-PCR methods, respectively. MLST method was used for genotyping, and Biometrics 8.0 software was used for cluster analysis of the typing results. Results:A total of 32 strains of Brucella were isolated in Guizhou Province and identified as Brucella melitensis ( B.melitensis) by BCSP31-PCR and AMOS-PCR methods. These strains were classified into 2 ST types (ST8 and ST39) by MLST method, with 28 strains of ST8 type(87.5%) and 4 strains of ST39 type (12.5%). The 28 strains of ST8 type were distributed in 7 cities (prefectures) of Guizhou Province, while the 4 strains of ST39 type were only found in Qianxinan Buyi and Miao Autonomous Prefecture. The cluster analysis results showed that ST8 and ST39 types strains were clustered in a group with the reference strain of B.melitensis, and there was only one nucleotide site difference between ST39 and ST8 types in the glk gene, indicating a close genetic relationship. Conclusions:B.melitensis is the main pathogen of the brucellosis epidemic in Guizhou Province in recent years. ST8 is the dominant MLST genotype in Guizhou Province.
