Chinese Journal of Primary Medicine and Pharmacy 2023;30(6):862-866
Objective:To investigate the relationship between peripheral blood lipid levels and hepatitis B-related liver cancer, and to provide a theoretical basis for the early prevention and treatment of liver cancer.Methods:A total of 188 patients with hepatitis B-related liver cancer who received treatment in The First Hospital of Shanxi Medical University from June 2018 to June 2021 met the inclusion and exclusion criteria and had complete data, were included in this study. They were divided into three groups: chronic hepatitis B group ( n = 72), hepatitis B cirrhosis group ( n = 62), and hepatitis B-related liver cancer group ( n = 54) according to different stages of the disease. All patients' medical records were obtained from the medical data room. Fasting venous blood was collected in all patients on the second day after admission to detect peripheral blood lipid, liver function, and other relevant indicators. General data and biochemical indicators were collected. The Kruskal-Wallis test was performed to compare the measurement data among groups. The chi-squared test was performed to compare the count data among groups. Spearman's correlation (bivariate) was performed. Binary logistic regression was performed to analyze the influential factors of liver cancer. Results:There were significant differences in the levels of total cholesterol (TC), triacylglycerol (TG), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C) among the three groups ( F = 32.14, 27.59, 10.88, 34.09, all P < 0.05). TC and LDL-C levels in the hepatitis B-related liver cancer group were significantly higher than those in the hepatitis B cirrhosis group ( F = -32.31, -50.19, both P < 0.05). There were no significant differences in TG and HDL-C levels between hepatitis B-related liver cancer and hepatitis B cirrhosis groups ( F = -10.69, 4.46, both P > 0.05). TC, TG, HDL-C and LDL-C levels in the hepatitis B cirrhosis group were significantly lower than those in the chronic hepatitis B group ( F = 53.30, 46.98, 24.61, 48.57, all P < 0.05). LDL-C level was positively correlated with the occurrence of liver cancer ( r = 0.20, P < 0.05). HDL-C level was negatively correlated with the occurrence of liver cancer ( r = -0.15, P < 0.05). LDL-C was an independent risk factor for liver cancer ( OR = 3.35, P < 0.05), and HDL-C was a protective factor for liver cancer ( OR = 0.12, P < 0.05). Conclusion:Compared with patients with chronic hepatitis B and hepatitis B cirrhosis, patients with hepatitis B-related liver cancer had abnormal peripheral blood lipid levels, which may be related to the abnormal lipid metabolism of tumor cells. Moreover, peripheral blood lipid levels may affect the occurrence and development of tumor cells.

Objective:To explore the effect of intravascular sodium nitroprusside (SNP) combined with hyaluronidase (HAase) plus urokinase (UK) in treating rat abdominal wall skin flap ischemia caused by HA induced artery embolism, and to compare the difference between thrombolysis with and without addition of sodium nitroprusside.Methods:Forty male Sprague-Dawley rats were injected with 10 μl of hyaluronic acid (HA) into the left inferior epigastric arteries, constructing the superficial epigastricl artery skin flap ischemic model in rats. The rats were randomly divided into four groups: a control group, and experimental groups A, B and C. Control and experimental groups A, B and C were treated with the following solutions 45 minutes after hyaluronic acid injection: physiological saline plus glucose was injected into the rats (control group); hyaluronidase (HAase) plus glucose injection was injected into the rats (experimental group A), hyaluronidase (HAase) plus urokinase (UK) was injected into the rats (experimental group B), hyaluronidase (HAase), urokinase (UK) plus sodium nitroprusside were injected into the rats (experimental group C). The changes of flaps were observed at 0 min, 3 days, 5 days and 7 days after operation. The difference of the area percentage of unperfused flap in the four groups was compared 7 days after operation. This study was carried out from July 2020 to March 2021 in the Medical Laboratory Animal Center of Weifang Medical University.Results:The unperfused area of flaps for the control group, experimental groups A, B and C were (100.00±0.00) %, (44.68±7.90)%, (34.01±8.77)% and (24.12±4.58)%, respectively. In the experimental group C, the scabby necrosis area was smaller than that of the experimental group A ( P<0.05); in the experimental group C, the scabby necrosis area was smaller than that of the experimental group B ( P<0.05); in the experimental group B, the scabby necrosis area was smaller than that of the experimental group A ( P<0.05). HE staining revealed that size and density of the embolus was significantly decreased after the addition of sodium nitroprusside. Conclusions:Sodium nitroprusside combined with hyaluronidase and urokinase can effectively improve the ischemia of the flap caused by HA induced artery embolism, increase the tissue perfusion, and reduce the necrotic area of the flap.

The present study was intend to clone and express the cDNA encoding Cyclophilin B (CyPB) of Schistosoma japonicum, its preliminary biological function and further immunoprotective effect against schistosome infection in mice. RT-PCR technique was applied to amplify a full-length cDNA encoding protein Cyclophilin B (Sj CyPB) from schistosomula cDNA. The expression profiles of Sj CyPB were determined by Real-time PCR using the template cDNAs isolated from 7, 13, 18, 23, 32 and 42 days parasites. The cDNA containing the Open Reading Frame of CyPB was then subcloned into a pGEX-6P-1 vector and transformed into competent Escherichia coli BL21 for expressing. The recombinant protein was renaturated, purified and its antigenicity were detected by Western blotting, and the immunoprotective effect induced by recombinant Sj CyPB was evaluated in Balb/C mice. The cDNA containing the ORF of Sj CyPB was cloned with the length of 672 base pairs, encoding 223 amino acids. Real-time PCR analysis revealed that the gene had the highest expression in 18-day schistosomula, suggesting that Sj CyPB was schistosomula differentially expressed gene. The recombinant protein showed a good antigenicity detected by Western blotting. Animal experiment indicated that the vaccination of recombinant CyPB protein in mice led to 31.5% worm and 41.01% liver egg burden reduction, respectively, compared with those of the control. A full-length cDNA differentially expressed in schistosomula was obtained. The recombinant Sj CyPB protein could induce partial protection against schistosome infection.

Objective:To deeply analyze differences in characteristics of neurosyphilis between male and female patients with neurosyphilis, as well as between patients with symptomatic neurosyphilis and those with asymptomatic neurosyphilis, and to provide reference for the prevention and control, clinical diagnosis and treatment of neurosyphilis.Methods:A total of 131 inpatients with neurosyphilis were collected from Department of Dermatology and Venereology, the First Affiliated Hospital of Anhui Medical University from June 2015 to December 2019, and their clinical manifestations and laboratory findings were retrospectively analyzed. These patients were grouped according to gender and neurological/psychiatric symptoms. Measurement data were compared by using two-independent-sample t test or Mann-Whitney U test, and enumeration data were compared by using chi-square test and Fisher′s exact test, to analyze differences in clinical characteristics and laboratory indicators between different groups. Results:Among the 131 patients, there were 72 with asymptomatic neurosyphilis (asymptomatic group) and 59 with symptomatic neurosyphilis (symptomatic group). The proportion of patients receiving syphilis treatment was significantly lower in the symptomatic group (10.17%) than in the asymptomatic group (98.61%, OR = 0.002, P < 0.001). The misdiagnosis rate at the first clinical visit was significantly higher in the male patients (50.00%) than in the female patients (24.49%, OR = 3.08, P = 0.004), as well as in the symptomatic patients (89.83%) than in the asymptomatic patients (0, OR = 13.00, P < 0.001). The proportion of symptomatic patients was significantly higher in male patients (57.32%) than in female patients (14.64%, OR = 4.14, P = 0.003). Compared with the female patients, the male patients showed significantly increased positive rates of toluidine red unheated serum test (TRUST) in the cerebrospinal fluid samples (52.44% vs. 26.54%, OR = 3.05, P = 0.004), increased proportions of patients with elevated levels of total protein (> 0.5 g/L) in cerebrospinal fluids (79.27% vs. 59.18%, OR = 2.64, P = 0.01), increased total protein levels in cerebrospinal fluids (0.76 ± 0.41 g/L vs. 0.56 ± 0.25 g/L, P = 0.002), and increased detection rates of brain magnetic resonance imaging abnormalities (72.22% vs. 44.90%, OR = 2.13, P = 0.039). The age at diagnosis of the symptomatic female patients (50.82 ± 9.31 years) was significantly higher than that of the asymptomatic female patients (42.30 ± 12.18 years, P = 0.038). The positive rate of TRUST in the cerebrospinal fluid samples was significantly higher in the patients with symptomatic neurosyphilis (55.93%) than in those with asymptomatic neurosyphilis (31.94%, OR = 2.70, P = 0.006), and so was the total protein level in cerebrospinal fluids (0.79 ± 0.46 g/L vs. 0.60 ± 0.24 g/L, P = 0.003) . Conclusion:The misdiagnosis rate of neurosyphilis is high at the first clinic visit; the condition of male patients is more serious than that of female patients; anti-syphilitic treatment history, gender and age may play some role in the development of neurosyphilis.
