Objective To establish a model that integrates ultrasound features and immunological characteristics for predicting the efficacy of neoadjuvant chemotherapy(NAC)in breast cancer patients.Methods A total of 203 breast cancer patients undergoing preoperative NAC at the Fifth Medical Center of the PLA General Hospital between July 2021 and July 2024 were screened.In line with the inclusion/exclusion criteria,177 patients were included.Data on ultrasound and immunohistochemistry was collected.These patients were divided into pathological complete response(pCR)and non-pathological complete response(non-pCR)groups based on postoperative pathology.Factors with P＜0.0 1 in univariate analysis were evaluated using multivariate Logistic regression.Independent predictive factors were used to construct and validate the ultrasound-immunohistochemical model via Bootstrap.Results The reduction rateof the maximum diameter of lesions,posterior echo attenuation,PR status and HER-2 status were identified as independent predictors of pCR(all P＜0.05).The model proved to be highly accurate and stable.Conclusion The model that combines ultrasound and immunohistochemical features can effectively evaluatep CR after NAC in breast cancer patients.

Objective To establish an HPLC method for the determination of alkaloids(epiberberine,coptisine,palma-tine,berberine)and catalpol in different ratios(1∶1,1∶10)of ancient and modern Qianjin Huanglian Pills,and to compare the differences in their contents.The content differences were compared to preliminarily evaluate the differences in the efficacy of Qianjin Huanglian Pills in the treatment of diabetes under different preparation processes and different ratios.Methods The alkaloid solvent was methanol∶ hydrochloric acid(100∶1).The detection conditions were as follows:C18 column,acetonitrile-0.05 mol·L-1 potassium dihydrogen phosphate solution(50∶50),detection wavelength 345 nm,column temperature 30℃,flow rate 1 mL·min-1,injection volume 10 μL.The catalpol solution was methanol∶ water(20∶80).The detection conditions were as follows:chromatographic column C18 column,methanol-0.1%phosphoric acid solution(1∶ 99),detection wavelength 210 nm,column temperature 30℃,flow rate 1 mL·min-1,injection volume 10 μL.Results The established method was spe-cific,and the separation effect of the five components was good.It exhibited a good linear relationship(R2＞0.999)in their respec-tive linear ranges.The repeatability,precision,stability,and sample recovery rate all met the requirements.The content of four alka-loids in the ancient method 1∶1 was the highest,and the content of catalpol was the lowest.The content of four alkaloids in the ancient method 1∶10 was the lowest;the content of 1∶1 in the present method was higher than that in the ancient method 1∶10,and the content of berberine in the present method 1∶10 was slightly lower than that in the present method 1∶1,and the rest were higher than that in the present method 1∶1.The PCA results showed that the chemical composition contents of the four kinds of Qianjin Huanglian pills were very different.Conclusion The method is simple,accurate,and reproducible,making it suitable for the quality control of Qianjin Huanglian Pills.It provides a theoretical basis for exploring the difference in efficacy of Qianjin Huanglian Pills.

Objective:To investigate the expression, prognostic value of acylphosphatase 1 (ACYP1) and its relationship with hepatocellular carcinoma (HCC) immune cell infiltration.Methods:The expression of ACYP1 in 374 cases of HCC was analyzed by using The Cancer Genome Atlas (TCGA) database. According to the median expression level of ACYP1 in HCC, the patients were divided into high expression (187 cases) and low expression group (187 cases). Fifty normal liver tissue were used as negative control. The differential expression, Kaplan-Meier survival analysis, univariate and multivariate Cox analysis were performed to evaluate the role of ACYP1 in the diagnosis and prognosis of HCC. The relationship between the expression level of ACYP1 and immune cell infiltration and immune checkpoint were analyzed through the TIMER database.Results:The expression level of ACYP1 in HCC (2.18±0.69) was higher than that in normal liver tissue (1.02±0.31), and the difference was statistically significant ( t=11.76, P<0.001). The survival of HCC patients with high ACYP1 was shorter than those HCC patients with low ACYP1 expression, and high expression of ACYP1 was an independent risk factor for poor prognosis of HCC patients ( HR=2.402, 95% CI: 1.483-3.891, P<0.05). The area under the curve of ACYP1 expression level in diagnosis of HCC was 0.965. The expression level of ACYP1 was significantly positively correlated with immune cell infiltration and immune checkpoints programmed cell death protein 1( r=0.288, P<0.001) and cytotoxic T lymphocyte-associated antigen 4 ( r=0.311, P<0.001). Conclusion:ACYP1 is a potential biomarker for HCC diagnosis and prognosis , as well as a potential therapeutic target.

Objective To investigate the related factors and preventive measures of delayed gastric emptying after operation for esophageal and cardiac carcinoma.Methods A total of 45 patients with delayed gastric emptying after operation for esophageal and cardiac carcinoma were selected as observation group,and 45 patients without delayed gastric emptying after operation for esophageal and cardiac carcinoma were selected as control group.Differences in the relevant factors were compared between the two groups.Results Single factor analysis showed that older age,high body mass index,short time education,malnutrition,poor mental state,rural residence,surgical incision,blood loss,long operation time,postoperative analgesia pump application,and the large amount of fluid volume were related risks of delayed gastric emptying (P ＜ 0.05).The Logistic regression analysis showed that older age (OR =4.15,95 ％ CI:1.89 ～ 26.30),bad psychological reaction (OR =3.96,95％ CI:1.38 ～ 25.38),long operation time (OR =3.40,95％ CI:1.11 ～ 20.28) and malnutrition (OR =3.02,95％ CI:1.09 ～ 19.35) were independent factors of delayed gastric emptying.Conclusion Delayed gastric emptying is one of the common complications after operation for esophageal and cardiac carcinoma,and the influencing factors are complex.

Objective To investigate the clinical effect of magnesium sulfate combined with nifedipine in the treatment of patients with pregnancy induced hypertension( HDCP) .Methods Retrospective study was used in this study and 116 patients with HDCP from January 2013 to July 2015 in department of obstetrics and gynecology from our hospital were divided into two groups, including routine group of 62 patients who received routine treatment +magnesium sulfate) and combination group of 54 patients who received routine treatment +magnesium sulphate +nifedipine.The clinical effect was analyzed after five days’ continuous treatment.Results The systolic blood pressure, diastolic blood pressure,24h urinary protein, random urine protein /creatinine,serum homocysteine (Hcy) and CRP values in combination group were lower than routine group (P<0.05).There were no statistical difference in maternal uterine inertia, neonatal asphyxia, fetal distress, postpartum hemorrhage rate between the two groups after the treatment.But the rate of cesarean section in the combination group(50.00%)was significantly lower than that in the routine group(68.25%)(P <0.05).Conclusion Magnesium sulfate combined with nifedipine in the treatment of patients with HDCP had better antihypertensive effect, and would not increase fetal adverse birth outcomes incidence and significantly reduce the rate of cesarean section.

BACKGROUND: Several studies have demonstrated that many American women who are at high risk of developing osteoporosis have higher levels of serum phosphorus. This indicates that some substances which can lower the serum level of phosphorus will supply a new and effective method to prevent and treat osteoporosis.OBJECTIVE: To observe the influences of porcine bone protein on bone mineral density (BMD) and serum levels of calcium and phosphorus in a rat model of osteoporosis.METHODS: Wistar rat models of osteoporosis were established by intramuscular injection of dexamethasone. Rat models were randomly divided into physiological saline, Jiegu Qili tablet, 50, 100, 200 mg/kg porcine bone protein groups. Rats that did not receive any treatments served as normal controls. After 12 weeks of treatment, serum was collected and serum levels of phosphorus and calcium were determined by biochemistry method. At the same time, tibia sections were made to determine tibial DMD by QDR-400 dual energy X-ray absorptiometry and to observe tibia marrow cavity by hematoxylin-eosin staining.RESULTS AND CONCLUSION: There was no significant difference in serum level of calcium among groups (P＞0.05).Compared with the physiological saline group, serum level of phosphorus in the 50, 100, 200 mg/kg porcine bone protein groups was significantly decreased (P ＜ 0.05). BMD was significantly higher in the 50, 100, 200 mg/kg porcine bone protein, Jiegu Qili tablet groups than in the physiological saline group (P ＜ 0.05). The tibia marrow cavity was smallest in the normal control group and largest in the physiological saline group. The tibia marrow cavity was larger in the 50, 100, 200 mg/kg porcine bone protein,Jiegu Qili tablet groups than in the physiological saline group. These results indicate that porcine bone protein cannot change the serum level of calcium, but it lowers serum level of phosphorus, and increases BMD, in a rat model of osteoporosis. However, the dose-dependent effect of porcine bone protein was not observed within the present experimental dosage. In addition, porcine bone protein can also reduce the marrow cavity of the tibia of rats with osteoporosis.

OBJECTIVETo identify the relationship between coagulation factor V (FV) gene single nucleotide polymorphisms (SNPs) and venous thromboembolism (VTE).

METHODSThe FV clotting activity (FV: C) and FV antigen (FV: Ag) in plasma of VTE group (111 patients) and normal control (110 patients) were detected using one-stage clotting assay and ELISA, respectively. Five pairs of primers of the F V polymorphisms including Asp79His, Arg306The, Arg306Gly, Arg506Gln and Ile359The/His1299 Arg were synthesized and amplified by PCR. The PCR products were digested by restriction enzyme using PCR-RFLP. The detected polymorphisms were confirmed by direct sequencing. The samples containing the polymorphisms were screened for coding regions of all F V exons with direct sequencing.

RESULTSThe plasma levels of F V: C and F V: Ag of VTE group and normal control were (106.9 +/- 28.0)%, (110.4 +/- 33.3)% and (102.4 +/- 30.9)%, (102.1 +/- 24.1)%, respectively. The plasma level of FV: Ag was significantly different between VTE group and normal control. However, there was no difference in F V: C levels. Polymorphisms for the fore mentioned 5 primer pairs were not found in either patients or normal controls. Polymorphism of His1299Arg was identified in 5 patients with VTE and 3 normal controls. And these 5 cases also combined Met1736Val polymorphism, 3 of them combined another Asp2194Gly polymorphism.

CONCLUSIONThe higher plasma level of F V: Ag contribute to venous thromboembolism. There is no relationship between polymorphisms of Asp79His, Arg306The, Arg306Gly, Arg506Gln, Ile359The and venous thromboembolism in Chinese studied. Polymorphism His1299Arg is higher in VTE group than in normal control, but has no statistical difference. Polymorphisms of His1299Arg, Met1736Val and Asp2194Gly are linked disequilibrium in Chinese Han population.
