The relationship between the inhibitory effect of tetrandrine ( Tet ) on neutrophil ( Nen ) lysomal enzyme ( ?-glu-curonidasc , P-G ) release & calcium ion were studied. It was found that calcium ion added to the medium increased p-G release from Neu During incubation. After intracellular calcium was depleted by EGTA, P-G release was signifcantly decreased. While calcium was added, increase in P-G release reappeared. It indicated that both intracellular & extracellular calcium may be involved in P-G release. Tet & v erapamil ( Ver ) not only inhibited ?-G release induced either by calcium or serum opsonized zymOsan, but also inhibited potential operated channel of Neu. It was concludted that the inhibitory effect of Tet on Neu lysomal enzyme release was concerned with its calcium antagonism.

Objective:
We aimed to evaluate changes towards liver fibrosis during entecavir(ETV)treatment by non-invasive fibrosis markers in chronic hepatitis B (CHB) patients who need antiviral therapy.
Methods:
Totally 303 HBeAg negative treatment-naive CHB patients were enrolled and liver biopsy was performed before starting antiviral therapy in this study. Totally 196 patients who need antiviral therapy were treated with ETV for at least 3 years. A clinical and virological evaluation was performed at baseline and again after 1, 2 and 3 years during ETV treatment. AST-to-platelet ratio index (APRI) was used to assess dynamic changes of liver fibrosis in HBeAg negative CHB patients after 1, 2, 3 years of ETV treatment.
Results:
All enrolled patients experienced liver biopsy at baseline. According to Metavir fibrosis stages, F1, F2, F3 and F4 patients were 107, 125, 54 and 17, respectively. The APRI score enabled the correct identification of patients with severe fibrosis (METAVIR F3-F4). The APRI values significantly decreased in F2 and F3 patients after 1 year ETV therapy (

Objective To explore the clinical features of chronic myelogenous leukemia (CML) combined with solid malignant neoplasms. Methods The clinical data of 8 CML patients with solid malignant neoplasms who were admitted to the Affiliated Tumor Hospital of Zhengzhou University, the Central Hospital of Nanyang City, the First Affiliated Hospital of Science and Technology University of Henan, and the Central Hospital of Xinxiang City from August 2006 to August 2018 were analyzed retrospectively. The clinical features, treatment and prognosis of the patients were summarized with the review of literature. Results Among the 8 patients, 3 were male and 5 female, aged 40-76 years, with a median of 50 years old. Seven cases were in CML chronic phase, and 1 was in accelerated phase. Seven patients were treated with tyrosine kinase inhibitor (TKI), and only 1 patient was treated with hydroxyurea. In 8 patients, two cases presented with synchronous multiple primary cancer (SMPC), 6 cases presented with heterochrony multiple primary cancer (HMPC). two patients received the operation, 1 patient received the operation and chemotherapy, 4 patients received chemotherapy, and 1 patient received the isotope treatment. One SMPC patient died and another one was under treatment, and 6 HMPC patients were under treatment. ConclusionsThe relationship between CML and solid malignant neoplasm is under discussion, but patients with CML and solid malignant neoplasm are not unusual. Clinicians should raise awareness to avoid misdiagnosis. The treatment should follow the two main lines that are comprehensive treatment and individualized treatment.

Objective:To investigate the feasibility, effectiveness and safety of indocyanine green (ICG) navigation in the surgical resection of abdominal wall endometriosis (AWE).Methods:Seven women undergoing surgery for AWE in First Affiliated Hospital of Sun Yat-sen University (from July 1, 2021 to October 1, 2021) were collected. After exposure of the focus, ICG were used intravenously (0.25 mg/kg) as fluorescent dye for the intraoperative evaluation of AWE vascularization. Resection of the AWE was guided by direct visualization of the focus under standard laparoscopy with a near-infrared (NIR) camera head. Surgical margin around the AWE (3, 6, 9 and 12 point) and the margin under the focus were obtained for postoperative pathological examination of endometriosis. Time from injection to fluorescence visualization, the proportion of fluorescence visualization, time of fully resection of AWE, side effects related to the use of ICG, perioperative complications as well as the pathological result of the surgical margins were recorded.Results:ICG fluorescence of the AWE were seen in 5 patients (5/7). The mean time from injection to fluorescence visualization was (46.7±9.8) s. The mean time of fully resection of AWE was (16.4±7.0) minutes. There were no side effects related to the use of ICG. The rate of class-A wound healing was 7/7. All of the surgical margins were confirmed endometriosis-negative by postoperative pathological examination.Conclusion:ICG fluorescence visualization could conduct accurate resection of AWE, which is clinically safe and effective.
