Objective To investigate the relationship between serum nitric oxide (NO) and bone metabolism in streptozotocin induced early diabetic (STZ DM) rats. Methods Twenty SD rats were divided into 2 groups, 12 STZ DM rats and 8 controls. Fasting blood glucose, HbA 1c , serum insulin, bone mineral density (BMD) (whole body, lumbar and femoral bone), bone metabolic parameters 〔such as serum calcium, vitamin D 3, parathyroid hormone (PTH), calcitonin, osteocalcin, and urinary pyridinoline/creatinine〕, as well as serum NO were measured. Results Compared with the controls, serum NO in STZ DM group significantly elevated 〔(51.3?11.9 vs 38.1?12.0)?mol/L, P

Objective To study the relationship between ATP level changes detected by hepatic 31P MRS with the pathologic changes of liver in rabbits and to investigate the diagnostic value of ATP level changes in acute hepatic radiation injury. Methods A total of 30 rabbits received different radiation doses ( ranging from 5,10,20 Gy) to establish acute hepatic injury models. Blood hepatic function tests, 31P MRS and pathological examinations were carried out 24 h after irradiation The degree of injury was evaluated according to hepatocyte pathology. Ten healthy rabbits served as controls. The MR examination was performed on a 1.5 T imager using a 1H-31P surface coil with 2D chemical shift imaging technique. The relative quantities of phosphomonoesters (PME), phosphodiesters (PDE), inorganic phosphate (Pi) and adenosine triphosphate (ATP) were measured. Analysis of variance was used to compare the results of 31P MRS and histopathology under various acute hepatic radiation injuries, and SNK was used further to conduct comparison between each other if there was significant difference. Results The ATP relative quantification in control( n= 10), mild ( n = 12), moderate ( n = 11 ), and severe ( n = 7 ) injury groups according to pathological grading were 1.83 ± 0. 33, 1.58 ± 0. 25, 1.32 ± 0. 07 and 1.02 ± 0. 18, with significant differences among them (F =22. 878 ,P ＜0. 01 ), and it decreased progressively with the increased degree of injury. The PDE index showed no significant trend for the evaluation of hepatic radiation injury. The area under the peak of β-ATP decreased with the increased severity of radiation injury. Conclusions The relative quantification of hepatic ATP levels can reflect the pathological severity of acute hepatic radiation injury. The decreasing hepatic ATP levels may be used as biomarker of acute liver injury following radiation.

Objective To study the expression and the clinical significance of glyican-3 (GPC3)in hepatocellular carcinoma (HCC)tissues.Methods Immunohistochemical method was performed to evaluate the expression of GPC3 in 54 cases of HCC tissues,46 cases of para-carcinoma tissues,22 cases of cirrhosis tissues,12 cases of normal liver tissues,the correlation between expression levels of GPC3 and clinicopathologic factors was analyzed.Results GPC3 protein was not expressed in normal livers tissues,the levels of GPC3 (7.39±3.64)and the positive rate (81.48%)in HCC tissues were significantly higher than para-carcinoma tissues (1.15±0.99,13.04%),cirrhosis tissues (0.32±0.56,4.54%),the difference was sta-tistically significant (P <0.05);with the increase of clinical stage ofHCC,the levels of GPC3 were increased,stage Ⅲ/Ⅳ(10.05±3.59)compared with stage Ⅰ (4.31±3.41),stage Ⅱ (7.14±3.63),and the difference was statistically signifi-cant (P <0.05).The positive rate of GPC3 was also increased(stage Ⅰ 69.23%,stage Ⅱ 81.81%,stage Ⅲ/Ⅳ 89.47%) and the difference was not statistically significant (P >0.05);the positive rate in HCC tissues was independent of sex,age, serum HBsAg,alpha-fetoprotein (AFP),tumor diameter,metastasis,clinical stage (P >0.05),only related to the cirrhosis (P <0.05).The high expression rate of GPC3 in HCC tissues was correlated with AFP,tumor diameter,cirrhosis,metasta-sis,clinical stage (P <0.05).Conclusion GPC3 has important clinical significance in the diagnosis of HCC,the expression level of GPC3 associated with the progression of HCC.

OBJECTIVE: To investigate the information acquired through the four diagnostic methods of traditional Chinese medicine in patients with bronchial asthma, and to classify the syndrome types. METHODS: Four hundred and thirty patients with bronchial asthma were randomly investigated. The information acquired through the four diagnostic methods was recorded and the database was established by Amos software, and then the data were analyzed by confirmatory factor analysis (CFA). RESULTS: After analyzing the data with 4 factors, 5 factors and 6 factors, we found that the results of CFA with 6 factors were in accordance with clinical practical experience. CONCLUSION: According to the results of CFA with 6 factors and with the standard regression coefficient 0.4 as primary and secondary critical points, the syndromes in patients with bronchial asthma can be classified into 5 types, which are syndromes of cold fluid retained in lung, phlegm-heat obstructing lung, wind-phlegm blocking lung, qi deficiency of lung and kidney and qi deficiency of spleen.

AIM To investigate the anti-neuroinflammation effects of 4-hydroxybenzyl aldehyde (4-HBAL) from Gastrodia elata Blume on acute cerebral ischemic injury in rats and its nechanism of action.METHODS The rat model of acute cerebral ischemic injury was induced by injecting arachidonic acid via intracarotid artery.Brain tissue samples were taken from the animals 3 h after the model of acute cerebral ischemic injury.Tumor necrosis factor-alpha (TNF-α) and interleukin-1 beta (IL-1β) were detected in brain tissue to evaluate the effects of 4-HBAL in vivo.Lipopolysaccharid (LPS)-induced activation of BV-2 microglia cells model was used to explore the anti-neuroinflammation mechanism of 4-HBAL.RESULTS The experimental results showed that 4-HBAL had a significant protective effect on acute cerebral ischemic injury.It could significandy decrease the contents of tumor necrosis factor-alpha (TNF-α) and interleukin-1 beta (IL-1β),and obviously inhibit the production of nitric oxide (NO),prostaglandin E2 (PGE2) and TNF-α in LPS-stimulated BV-2 cell,and increase the production of interleukin-10 (IL-10) and transforming growth factors-β (TGF-β) in BV-2 cell.CONCLUSION The mechanism of 4-HBAL may be related to the suppression of the excessive activation of microglia after cerebral ischemia and the promotion of the transformation of microglia into anti-inflammatory phenotype.

OBJECTIVE: To evaluate the efficacy and safety of the sublingual immunotherapy with dermatophagoides farinae drops on patients with allergic rhinitis. METHOD: One hundred and twelve cases were collected from adult patients with dust-mite allergic rhinitis of our hospital who could adhere to treatment and regular follow-up. These patients were randomly allocated to receive either sublingual immunotherapy (SLIT group, n = 56) or medical treatment (Control group, n = 56). To evaluate the clinical efficacy by side effects which were registered, symptom and medication scores which were assessed and rhinoconjunctivitis quality of life questionnaire (RQLQ) which was completed in the baseline and two years after treatment. RESULT: Dropouts after the 2 years' treatment were 5 of SLIT group and 4 of Control group respectively. SLIT group induced the significant reductions on both the symptom scores (7.81 ± 3.14 to 3.89 ± 2.01, P < 0.0 1) and the medication scores (2.86 ± 0.75 to 0.44 ± 0.06, P < 0.01). Meanwhile, Control group induced the reductions on both the symptom scores (8.01 ± 3.32 to 5.20 ± 2.43) and the medication scores (2.95 ± 0.80 to 1.75 ± 0.40). There were significant differences (P< 0. 01) in symptom and medication scores between the two groups after 2-year treatment. The patients in SLIT group had fewer symptoms and lower intake of medication. There were statistically significant differences in RQLQ between SLIT group [19 (15,22)] and Control group [36 (26,47)] after two years treatment (Z = -5. 21, P < 0.01). SLIT group also had significant improvement in RQLQ (Z = -6.10, P < 0.01) between before and after the treatment. There were 4 patients who showed adverse reactions in SLIT group (3 occurred in increment period, and 1 occurred in the maintenance period). The incidence of adverse reactions was 7.14%. No severe systemic side effects were registered. CONCLUSION SLIT with standardized dermatophagoides farinae drops in China is safe and effective to patients with allergic rhinitis.

OBJECTIVETo assess the anxiolytic effect of Anshenfang granules (ASF), a compound traditional Chinese medicinal preparation, on anxiety in rats and the mechanism of its actions.

METHODSMale Wistar rats with anxiety induced by chronic emotional stress were randomized to receive treatments with diazepam or ASF at high, medium or low doses. The behavioral changes of the rats were evaluated using plus-maze test, after which the rats in normal control group, model group, and medium AFS dose group were sacrificed to measure the hippocampal contents of glutamic acid and γ-aminobutyric acid (GABA) using high-performance liquid chromatography (HPLC); immunohistochemistry was employed to evaluate the expressions of GABAA receptor and N-methyl-D-aspartate receptor 1 (NMDAR1).

RESULTSPlus-maze test showed obvious anxiety behaviors in the model group, which were significantly meliorated by diazepam and ASF, especially at the medium dose. Hippocampal glutamate levels increased and GABA decreased significantly in the model group, and such changes were obviously attenuated, by comparable amplitudes, by treatments with diazepam and medium-dose ASF. The model group showed significantly diminished GABAA receptor-positive cells and increased NMDAR1-positive cells, which were improved by diazepam and ASF at the medium dose.

CONCLUSIONASF produces strong anxiolytic effect in rats by increasing the content of GABA in the brain, enhancing GABAA receptor expression, reducing glutamic acid content, and decreasing NMDAR1 expression.

Objective:To explore the risk factors of deep vein thrombosis (DVT) in hospitalized rehabilitation patients.Method:Clinical data of 1 130 patients, 737 males and 393 females with the mean age of 63.0 (54.0, 73.0) years, admitted in the Department of Rehabilitation Medicine of the Second Hospital of Jiaxing from August 2021 to September 2022 were retrospectively analyzed. Patient underwent vascular color ultrasound examination, DVT was detected in 194 cases (DVT group) and not detected in 936 cases (control group). The general clinical data, venous thromboembolism (VTE) risk stratification and traditional VTE risk factors of patients were documented. The risk factors of DVT formation were analyzed with multivariate logistic regression.Results:Compared with the control group, the DVT group had a higher proportion of patients with older age, longer length of hospital stay, and positive D-dimer (all P<0.001). The proportion of patients with high risk of VTE in the DVT group was 49.5% (96/194), which was higher than that in the control group (27.0% (253/936), P<0.01). The proportion of patients with age≥70 years, previous venous thromboembolism, and history of recent (≤1 month) trauma or surgery in the DVT group was significantly higher than that in the control group (all P<0.001). The proportion of patients with primary diagnoses of quadriplegia, hemiplegia or other motor disorders in the DVT group was significantly higher than that in the control group ( P<0.01). Multivariate logistic regression analysis showed that old age ( OR=1.014, 95% CI: 1.012-1.016), length of hospital stay ( OR=1.001, 95% CI: 1.001-1.002), positive D-dimer ( OR=2.508, 95% CI: 2.368-2.655), high risk of VTE ( OR=1.178, 95% CI: 1.10-1.250), quadriplegia ( OR=2.776, 95% CI: 2.552-3.021), hemiplegia ( OR=3.232, 95% CI: 2.996-3.488), motor disorders ( OR=2.308, 95% CI: 2.110-2.525), paraplegia ( OR=1.878, 95% CI: 1.622-2.175), previous venous thromboembolism ( OR=1.385, 95% CI: 1.314-1.460), history of recent (≤1 month) trauma or surgery ( OR=1.987, 95% CI: 1.886-2.093) (all P<0.001) were independent risk factors for DVT in rehabilitation inpatients. Conclusion:Age, length of hospital stay, primary diagnosis of quadriplegia, hemiplegia, paraplegia or other motor disorders, positive D-dimer, high risk of VTE, previous venous thromboembolism, and history of recent trauma or surgery are independent risk factors for DVT in rehabilitation specialty inpatients.

Objective To investigate the apolipoprotein (a) [apo(a)] polymorphism in the patients with type 2 diabetes mellitus and its relationship with complications.Methods In this study, we tested apo(a) phenotype via modified Utermann and Guo method in the 40 non-diabetic controls and 176 subjects with type 2 diabetes and analyzed the relationship between apo(a) phenotypes and micro- and macrovascular complications, including nephropathy, neuropathy, retinopathy, hypertension, coronary heart disease and cerebral infarction.Results Among the 40 non-diabetic controls, the frequencies of S3S2, S4 and S4S2 were 20%, 70% and 10% respectively and the serum lipoprotein(a) [Lp(a)] level was 0.08±0.07 mg/L. While the frequencies of S2, S3, S3S2, S4, S4S2, S4S3 were 18.18%, 20.45%, 17.05%, 34.09%, 4.55% and 5.68% in the diabetics and the Lp(a) concentration was 0.13±0.11 mg/L, with significant difference between the diabetics and non-diabetic controls. In comparison with the diabetics without complications, the frequency of apo(a) phenotype significantly differed in patients with nephropathy, nephropathy, hypertension, coronary heart disease and cerebral infarction except for diabetic retinopathy. In comparison with patients with S2 phenotype, the levels of fasting plasma glucose (FPG), 2-hour postprandial plasma glucose (2hPG) and glycated hemoglobin A1c (HbA1c) were lower in patients with S4 phenotype. The concentration of Lp(a) and urine albumin index (Alb/Cr) were significantly different among diabetics with different apo(a) phenotype, the highest being in patients with S2, secondly S3, and the lowest S4.Conclusion There were significant differences in the frequency of apo(a) phenotype between subjects with type 2 diabetes and non-diabetic controls, and also in diabetics with or without microvascular and macrovascular diseases. The underlying linkage might be microalbuminuria and insulin resistance.
