Objective To observe the effect of ginsenosides (GS) on the action of glucocorticoid (GC) in down-regulating glucocorticoid receptor (GR), and to explore the mechanism. Methods The rat model with hepatic artery ligation (HAL) was established and treated with GS and dexamethasone (DEX). Serum corticosterone level, maximal GK binding capacity (GR Bmax), K<,d> and GR mRNA in liver cells were detected 12 h after HAL. Results The levels of corticosterone in GS group and model group were higher than those in GS + DEX group, DEX group and normal group (all P < 0.01). The levels of corticosterone in GS + DEX group and DEX group were higher than that of normal group (both P <0.01). Compared to model group, GR Bmax in GS group was higher (P < 0.05), GR Bmax in GS + DEX group was lower (P < 0.05), but higher than that of DEX group (P <0.01). The expression of GR mRNA in GS group was significantly higher than model group (P < 0.01), but GR mRNA expression in DEX group was lower than that in model group, normal group and GS + DEX group (P <0.01). Conclusion GS partially reverses the down-regulation of GC on GR Bmax and GR mRNA, but it has no effect on serum corticosterone level in the rat model with HAL.

To investigate the effects of a formula of components from Shengmai Powder, a compound traditional Chinese herbal medicine, on glucocorticoid receptor (GR) in rats after thermal injury.

Impaired clearance of apoptotic cells is important in the pathogenesis of autoimmune disease.C-reactive protein (CRP) is an acute phase protein that plays a major role in the regulation of the autoimmune and inflammatory response .CRP has a role in the clearance of bacteria and dying and altered cells through binding to phosphocholine and might also have more complex immunomodulatory functions . CRP function as opsonins for pathogens and dying and apoptotic cells through activation of the complement pathway and through binding to Fcγreceptors , and is associated with the clearance of apoptotic cells and nuclear antigen , thus becoming a protective molecule against pathogenic autoimmune responses in general . Measurement of serum CRP level is in widespread clinical use as a sensitive marker of inflammation and autoimmune disease , particularly in relation to the use of the CRP-based disease activity score in the evaluation of rheumatoid disease.

OBJECTIVE: To establish a multidrug-resistant cell line BEL-7402/5-FU of hepatocellular carcinoma (HCC). METHODS: BEL-7402/5-FU was induced by pulse therapy combined with continuous stepwise exposure to 5-fluorouracil in vitro. MTT assay was used to determine its multidrug resistance (MDR). Biological characteristics of the BEL-7402/5-FU cell line were observed including morphological changes, cell growth curve, population doubling time, plate cloning efficiency, adherence rate, cell cycle distribution, chromosome and tumorigenicity. Accumulation amount of adriamycin (ADM) in cytoplasm was measured by flow cytometry. The protein expression of thymidylate synthase (TS) was evaluated by immuno-cytochemical method. RESULTS: The acquired MDR cell line of BEL-7402/5-FU was established successfully. The BEL-7402/5-FU cells showed cross-resistance to ADM, vincristine (VCR), methotrexate (MTX) and oxaliplatin (OHP), whereas still sensitive to hydroxycamptothecin (HCPT). The BEL-7402/5-FU cells tended to grow in clusters in vitro. It was found that the population doubling time of BEL-7402/5-FU cells was longer than that of its parental cells. The plate cloning efficiency and the adherence rate of BEL-7402/5-FU cells at the 2nd and 3rd hour were both lower than those of the parental cells. The distributing proportion of BEL-7402/5-FU cells in G(0)/G(1) phase was less than that of the parental cells, whereas the distributing proportion of BEL-7402/5-FU cells in S phase was higher than that of the parental cells. The accumulation amount of ADM in cytoplasm of BEL-7402/5-FU cells was significantly lower while the expression level of TS protein of which was highly up-regulated as compared with those of the parental cells. CONCLUSION: Establishment of the human HCC cell line BEL-7402/5-FU might be beneficial to the studies of 5-Fluorouracil acquired MDR mechanisms and the selection of reversal modifiers.

Objective : To investigate the epidemiological and clinical characteristics of cases with pertussis in Yiwu City, Zhejiang Province, so as to provide insights into pertussis diagnosis and control. Methods: A total of 186 patients with definitive diagnosis of pertussis in medical institutions in Yiwu City from November 1, 2020 to August 31, 2022 were recruited, and subjects' demographic, clinical symptoms and history of pertussis vaccination were collected using questionnaire surveys. The temporal, population, and spatial distribution and clinical symptoms of pertussis were analyzed using a descriptive epidemiological method, and the clinical characteristics of pertussis patients with different doses of pertussis vaccination were compared. Results: Pertussis was found to predominantly occur during the period between July and November (101 cases, 54.30%), and the three highest-incidence regions included Jiangdong Street, Beiyuan Street and Choujiang Street (87 cases, 46.77%). The 186 pertussis cases included 105 males (56.45%) and 81 females (43.55%), and included 144 cases with age of onset under 7 year (77.42%). Preschool and diaspora children were predominant among all pertussis cases, and the main clinical symptoms included spasmodic cough (97 cases, 52.15%), post-tussive vomiting (82 cases, 44.09%) and aggravated cough at night (77 cases, 41.40%). Routine blood tests measured 119 cases with abnormal white blood cell counts (63.98%), 137 cases with abnormal lymphocyte counts (73.66%), 39 cases with abnormal neutrophil counts (20.97%), 21 cases with abnormal platelet counts (11.29%) and 111 cases with abnormal hemoglobin concentrations (59.68%). There were 55 cases that were unvaccinated (29.57%), 23 cases that were not fully vaccinated (12.37%), and 108 cases that were fully vaccinated (58.06%). There were significant differences among pertussis cases with different doses of vaccination in terms of age, incidence of post-tussive vomiting, percentage of abnormal platelet counts and percentage of hemoglobin concentrations (all P<0.05). Conclusions The majority of pertussis cases are preschool and diaspora children in Yiwu City from November 1, 2020 to August 31, 2022, and the clinical symptoms mainly include spasmodic cough, post-tussive vomiting and aggravated cough at night, with atypical symptoms. The capability for differential diagnosis of pertussis is required to be improved in medical institutions.

Objective To evaluate the mid-term and long-term effects of early endovascular emboli-zation in treating ruptured posterior communicating artery aneurysm. Methods Early endovascular embolization therapy was carried out in 36 patients with ruptured posterior communicating artery aneurysm (36 aneurysms in total), and the effects of embolization therapy were evaluated by using Raymond grading method. The unified imaging review program was formulated, and the mid-term and long-term effects were evaluated at half, 1, 2, 3 and 5 years after the treatment. Results The technical success rate was 100% in 36 patients (36 aneurysms in total). Raymond grading evaluation showed that gradeⅠwas seen in 32 patients, gradeⅡ in 2 patients, and grade Ⅲ in 2 patients. Recurrence of aneurysm was found in 5 patients (13.89%) at half (n=1), 2 (n=1), 3 (n=1) and 5 years (n=2) after the treatment. Re-rupture of the recurrent aneurysm was seen in one patient (2.78%). No death occurred during the following-up period. Conclusion Early endovascular embolization for ruptured posterior communicating artery aneurysm can effectively improve the prognosis of subarachnoid hemorrhage, and regular imaging examination can promptly detect the recurrence of aneurysm. Effective interventions are helpful for preventing deterioration and rupture of aneurysm.
