Objective To investigate the clinical effects of treatment of chronic pulmonary heart disease (CPHD) at acute stage with sodium ferulate and Ciwujia injection. Methods 90 cases of CPHD at acute stage were recruited into treatment group 1, treatment group 2 and control group. The control group was treated with consistent inhalation of oxygen,antibiotics, and symptomatic therapies like relieving cough, removing sputum, and stopping wheeze. The treatment group 1was treated with sodium ferulate, Ⅳ 0.2g, once daily for successive 14days, in addition to the conventional treatment. The treatment group 2 was treated with Ciwujia Injection, 100ml Ⅳ, once daily for successive 14 days. Observe the curative effect and the changes of blood gas analysis indexes (PAo2, PaCO2, SAO2) and bemorheological indexes (whole blood high-cutting viscosity, whole blood low-cutting viscosity, whole blood recovery viscosity, erythrocyte aggregation index, and HCT) before and after treatment. Result Compared with the control group, both treatment groups got improvement in blood gas analysis indexes and hemorheological indexes and curative effect, but no significant difference between the two groups (P＞0.05).Conclusion both sodium ferulate and Ciwujia injection had good results in treating CPHD at acute stage, and there was no difference between the two medicines in terms of curative effects.

Objective To study the clinical efficacy of electromyography biofeedback on dystonia after hepatolenticular degeneration.Methods 40 patients with dystonia after hepatolenticular degeneration were divided into treatment group (n=20) and control group (n=20).All patients were treated with copper-cleaning, clonazepam and benzhexol hydrochloride etc., and acupuncture. The treatment group wastreated with electromyographic biofeedback in addition. They were assessed with modified Ashworth scale, modified Barthel index, and ankledorsiflexion active range of motion. Results The lower extremities function of all patients improved after treatment (P<0.05) and thetreatment group improved more than the control group (P<0.05). Conclusion Electromyography biofeedback is more effective to improvethe lower extremities function and activity of daily living in patients with hepatolenticular degeneration following dystonia.

Objective To investigate early renal damage of chronic hepatitis B (CHB) patients and the risk factors related to their renal function. Methods CHB patients who visited the second people’s hospital but did not receive systemic treatment were enrolled in our study. Those who visited for general check-up with no hepatic findings during the same period were selected as control group. Glomerular filtration rate (GFR) of all the participants were estimated by simplified MDRD equation and CKD-EPI equation (designated as M-eGFR and C-eGFR respectively). Influence factors of eGFR were statistically analyzed. Results In the total 528 cases in CHB group, 88 (16.67%) and 62 (11.74%) suffered declined M-eGFR and C-eGFR respectively. By contrast, 10 (8.77%) and 6 (5.26%) cases in the total 114 cases in control group present declined M-eGFR and C-eGFR ac?cordingly. Percentages of renal function impairment, estimated by both M-eGFR and C-eGFR, were higher in the CHB group than those in control group. The difference was statistically significant (χ2=4.518, P<0.05;χ2=4.156, P<0.05). Multiple linear regression analysis indicated that age, HBsAg and body mass index (BMI) were risk factors of M-eGFR while age, HBsAg, gender and serum albumin were risk factors of C-eGFR. On the other hand, HBV-DNA and HBeAg were not risk factors for M-eGFR or C-eGFR. Conclusion HBV infection can lead to early renal damage. Age and HBsAg are main risk factors of renal function impairment. Therefore, renal function should be scrutinized in CHB patients.

ObjectiveTo verify the therapeutic efficacy of acupuncture plus speech training and psychological intervention in treating dysarthria in hepatolenticular degeneration (Wilson’s disease).MethodSixty patients were randomized into a control group, a treatment group, and a combined group, 20 in each group. The three groups all received conventional treatments including removal of copper, liver protection, and brain protection, based on which, the control group also received speech training, the treatment group received acupuncture based on the treatments given to the control group, and the combined group received psychological intervention based on the treatments given to the treatment group.ResultAfter 2-month treatment, in comparing the Frenchay Dysarthria Assessment, the combined group showed a more significant improvement than the treatment group and control group (P<0.05); the total effective rate was 75% in the combined group, versus 25% in the treatment group and 10% in the control group, and the total effective rate of the combined group was significantly higher than that of both treatment group and control group (P<0.05).ConclusionAcupuncture plus speech training and psychological intervention can markedly improve the dysarthria symptoms of patients with Wilson’s disease, and recover their speech function and help them to go back to society.

ObjectiveTo study the clinical efficcacy of combined therapy of acupuncture, transcutaneous electrical nerve stimulation and swallowing function training in the treatment of dysphagia for hepatolenticular degeneration.MethodsSixty patients with dysphagia for hepatolenticular degeneration were divided into three groups: group A treated with acupuncture, transcutaneous electrical nerve stimulation and swallowing function training, group B treated with acupuncture and swallowing function training, and group C treated with transcutaneous electrical nerve stimulation and swallowing function training. The three groups had all been treated for two courses of treatment(30 d).ResultsThe therapeutic effect of group A outweighed groups B and C and the socres of water swallow test and standardized bedside swallowing assessment(SSA) were higher in group A than in groups B and Cafter the first course of treatment(P＜0.01), while there were no significant difference among the three groups (P>0.05) after the second course of treatment.ConclusionCombined therapy of acupuncture, transcutaneous electrical nerve stimulation and swallowing function training is effective to improve the swallowing function of hepatolenticular degeneration following dysphagia.

An approach was proposed to evaluate preparation technology by means of fingerprint-peak matching technology of high performance liquid chromatography with diode array detector (HPLC-DAD).Similarity and hierarchical clustering analysis (HCA) were applied to identify the 15 batches of Xiaochaihu granules from different manufacturers and our laboratory,and peak pattern matching between the composite formulae and Radix Bupleuri Chinensis,which was one of the main ingredients of Xiaochaihu granules,was utilized to evaluate the preparation technology of Xiaochaihu granules via the indexes of the relative deviation of retention time (RT) and UV spectrum feature similarity of their corresponding peaks.Eleven matching peaks were found between Xiaochalhu granules and Radix Bupleuri Chinensis.However,the saikosaponin A and saikosaponin D,which are the important active components in Radix Bupleuri Chinensis,were not found in Xiaochaihu granules from any manufacturers.The peak areas of 11 characteristic peaks of Xiaochaihu granules samples formed a matrix of 11 × 15.The result of HCA showed that Xiaochaihu granules samples were divided into four kinds of category.Xiaochaihu granules samples from the same manufacturer were basically clustered of the same category.The results suggested that the saikosaponin A and saikosaponin D are prone to structural transformation under the condition of decoction and in the presence of the organic acidic components.These active components,existing in raw herb,might transform to a series of non-active secondary saikosaponin due to unfavourable preparation technology.So the conventional decoction-based preparation technology of Xiaochaihu granules might greatly affect its quality and therapeutic effectiveness. This study demonstrates that fingerprint-peak matching technology can not only be used for quality control of this composite formulae,but also provide some guidance for preparation technology of Xiaochaihu granules.

Objective To evaluate the significance of serum 8-hydroxy-deoxyguanosine acid ( 8-OHdG) in the diagnosis of nonalcoholic steatohepatitis ( NASH).Methods Patients or healthy subjects were enrolled at the Second Hospital of Tianjin Medical University and the Second People ′s Hospital of Tianjin from May 2013 to December 2015.A total of 41 patients with nonalcoholic fatty liver disease were enrolled in the study , including 20 nonalcoholic simple fatty liver ( NAFL) patients and 21 NASH patients whose diagnosis were proven by liver biopsy.The other 32 healthy subjects were studied as controls.Serum 8-OHdG, ALT, AST and GGT were tested.Nonalcoholic fatty liver disease activity score ( NAS ) and expression of 8-OHdG in liver was investigated between NAFL patients and NASH patients.The correlations between serum 8-OHdG and serum ALT , AST, GGT, and 8-OHdG in liver tissue in NASH group were investigated.In addition , the receiver operating characteristic ( ROC) curve analyses for ALT and 8-OHdG levels were performed in NAFL patients and NASH patients , and the cut-off value was determined.Results Serum 8-OHdG values in healthy controls , NAFL and NASH patients were (0.19 ±0.16) μg/L, (0.22 ±0.16) μg/L, (0.42 ±0.21) μg/L respectively.The serum 8-OHdG and serum ALT, GGT and 8-OHdG in liver tissue were all positively correlated in NASH group with respective correlation coefficient r values as 0.454 7, 0.382 9, and 0.497 6.AUC of 8-OHdG was 0.901 with cut-off value 0.39 μg/L.Its sensitivity was 88.3%and specificity was 81.5%, which were higher than those of ALT.Conclusion The value of serum 8-OHdG would be used as a marker for the diagnosis of NASH.

Objective To study the therapeutic effect of anti-CD80 bivalent antibody on mouse lu-pus nephritis and to explore the possible molecular mechanism. Methods A mouse model of lupus nephritis was established through intraperitoneal injection of 0. 5 ml of pristine in female C57BL/6J mice. Appearance of urinary protein and significantly increased levels of peripheral antinuclear antibody ( ANA) and anti-doub-le-stranded DNA ( anti-dsDNA) antibody in the fourth month after injection indicated that the mouse model was established successfully. Then the mice were divided into two groups including anti-CD80 bivalent anti-body intervention group (injected with 200μg of anti-CD80 bivalent antibody at day 1, 3, 5, 8 and 15, fol-lowed by three times of injection with an interval of one month) and model group ( injected with the same protein using the same strategy). A normal control group was set up accordingly. Albustix test paper was used to monitor the dynamic changes in mouse urinary protein. Flow cytometry was used to analyze the acti-vation of immune-related cells in spleen. Levels of autoantibodies ( ANA and anti-dsDNA) and levels of IFN-γ and IL-4 in serum were detected by indirect immunofluorescence assay. Renal tissue samples were an-alyzed with hematoxylin and eosin ( HE) staining and immunocomplex ( IC) assay. Results Urinary pro-tein level of the anti-CD80 bivalent antibody intervention group was significantly lower than that of the model group (P<0. 05). Activated macrophages, dendritic cells, neutrophils and B cells in spleen tissues of the anti-CD80 bivalent antibody intervention group were significantly less than those of the model group ( P<0. 05), and the numbers of CD4+ and CD154+ T cells were significantly less than those of the model group (P<0. 05). Positive rates and titers of ANA and dsDNA in serum samples of the intervention group were lower than those of the model group (P<0. 05). Levels of IFN-γand IL-4 in serum samples of the interven-tion group were decreased as compared with those of the model group (P<0. 05). HE staining and immuno-fluorescence assay showed that glomerular inflammatory injury and necrosis were alleviated and kidney im-mune complex deposition was reduced after anti-CD80 bivalent antibody intervention. Conclusion Anti-CD80 bivalent antibody specifically binds to the CD80 molecule on antigen presenting cell surface, blocks the CD80/CD28 co-stimulatory signaling pathway and down-regulates the body′s immune response, which al-leviates and reverses the lupus-like nephritis-induced pathological damages in mice.

For the high-risk population, early screening and diagnosis are important measures to achieve good control of liver cancer and reduce the burden of liver cancer, and determining the high-risk population of liver cancer and formulating appropriate liver cancer screening strategies are the key to realizing the early screening and diagnosis of liver cancer. The risk assessment model for liver cancer is an important method for rapid and convenient identification of the high-risk population of liver cancer. Based on the risk stratification of liver cancer, the methods such as imaging technology, serological markers, liquid biopsy, metabolomics, and glycomics can be used for accurate early screening and diagnosis of liver cancer, so as to achieve the goal of early treatment.

Objective:To evaluate the effect of long-term intake of ω-3 polyunsaturated fatty acids (ω-3 PUFAs) on the activation of hippocampal microglia in a mouse model of postoperative cognitive dysfunction (POCD).Methods:Ninety-six clean-grade healthy male C57BL/6 mice, aged 8 weeks, weighing 18-24 g, were stratified according to body weight and divided into 4 groups ( n=24 each) by a random number table method: control diet group (group C), ω-3 PUFAs group (group ω), control diet plus POCD group (group C+ P) and ω-3 PUFAs plus POCD group (group ω+ P). Mice were fed a special ω-3 PUFAs diet (DHA 0.14 g/100 g, EPA 0.03 g/100 g) for 12 weeks in group ω and group ω+ P, while mice were fed with a control diet for 12 weeks in group C and group C+ P.Tibial fracture procedures were performed under isoflurane anesthesia to develop the POCD model after 12 weeks of feeding.The fear conditioning test and Y maze test were performed on 1st and 3rd days after developing the model.The mice were sacrificed after behavioral tests, and the hippocampal tissues were removed for determination of the contents of docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) (by gas chromatography-mass spectroscopy), density of Iba-1 positive microglia (by immunofluorescence staining), and expression of mature brain-derived neurotrophic factor (mBDNF) and precursor brain-derived neurotrophic factor (pro-BDNF) (by Western blot), and contents of interleukin-1beta (IL-1β) and interleukin-6 (IL-6) (by enzyme-linked immunosorbent assay). Results:Compared with group C, the contents of DHA and EPA were significantly increased, the percentage of freezing time in the contextual test was increased, mBDNF/pro-BDNF ratio was increased ( P<0.05), no significant change was found in the rotation accuracy in Y maze test, density of Iba-1 positive microglia and contents of IL-1β and IL-6 in hippocampus ( P>0.05) in group ω ( P<0.05), and no significant change was found in the contents of DHA and EPA ( P>0.05), the percentage of freezing time in the contextual test and accuracy of rotation in Y maze test were decreased on 1st and 3rd days after operation, the density of Iba-1 positive microglia and contents of IL-1β and IL-6 were increased, and mBDNF/pro-BDNF ratio was decreased in group C+ P ( P<0.05). Compared with group C+ P, the contents of DHA and EPA were significantly increased, the percentage of freezing time in the contextual test and accuracy of rotation in Y maze test were increased on 1st and 3rd days after operation, the density of Iba-1 positive microglia and contents of IL-1β and IL-6 were decreased, and mBDNF/pro-BDNF ratio was increased in group ω+ P ( P<0.05). Conclusions:Long-term intake of ω-3 PUFAs can improve cognitive function in a mouse model of POCD, and the mechanism may be related to inhibition of activation of hippocampal microglia, reduction of inflammatory responses, and thus increasing the mBDNF/Pro-BDNF ratio.
