Objective To investigate the therapeutic value of Shuxuetong injection in patients with acute coronary syndrome(ACS).Methods 89 ACS patients were divided randomly into two groups: control group(n =44) and experimental group(n=45).The conventional therapy was used in the control group while Shuxuetong was added in the experimental group.The course of treatment was two weeks.Thromboxane B2(TXB2) and 6-keto-prosta-glandin F1a (6-K-PGF1a) were detected by radio-immunity before and after therapy.Homocysteine were tested by corpuscle enzyme linked immunosorbent assay.Results TXB2 was obviously lower in the experimental group [(554.2±303.2) ng/L] and the control group [(737.2±299.3 ) ng/L ] after treatment than that before treatment (P<0.05).Homocysteine was obviously lower in the experimental group [(10.42±2.99 )μmol/L ] and the control group [(16.39±2.29) μmol/L ] after treatment than that before treatment (P < 0.05 ).6-K-PGF1a was obviously higher in the experimental group[(328.4±99.6) ng/L] and the control group[ (234.5±96.2) ng/L] after treat-ment than that before treatment (P<0.05).TXB2 and homoeysteine in the experimental group were obviously lower than those in the control group after treatment(P<0.05). 6-K-PGF1 a in the experimental group was obviously high-er than those in the control group after treatment (P<0.05).Conclusion Shuxuetong injection could degrade the level of TXB2 and HCY, increase the level of PGF1 a and improve the balance of TXB2/PGF1a, so Shuxuetong is ef-fective in treating acute coronary syndrome.

Objective To summarize the lung HRCT findings of lung Langerhans cell histiocytosis (LCH) in children. Methods A total of 54 children with lung LCH pathologically proved in our institute from September 2006 to December 2014 were retrospectively reviewed. Patients were subdivided into two subgroups, diffuse type (n=29) and localized type (n=25). In addition, 32 children with LCH but without pulmonary infiltration were selected as control group. HRCT findings of 54 LCH with lung involvement were reviewed and analyzed for distribution pattern. The age of onset, illness duration and pulmonary function were compared between the lung LCH group and the control group. The differences of HRCT findings in LCH patients between diffuse type and localized type were compared with χ2 test. The differences on the onset age, illness duration and pulmonary function between the LCH group with lung involvement and control group were compared with non-parametric test(Mann-Whitney U Test). The differences of pulmonary function between the LCH group with lung involvement and control group were compared with Fisher exact probability test. Results The signs of pulmonary LCH on HRCT included lobular hyperinflation (n=26), interlobular septa thickening (n=11), cystic lesions (n=11), ground?glass opacity (n=10), nodules (n=9), and centrilobular nodules (n=6). The signs presented in 21, 8, 7, 9, 4 and 6 cases in diffuse type group respectively and 5, 3, 4, 1, 5, 0 in localized type group. Among them, lobular hyperinflation, ground?glass opacity and centrilobular nodules were more prevalent in the diffuse group. The difference was statistically significant (χ2=14.77,2.01,0.55,4.84,0.06 and 3.91, P<0.05). The onset age of LCH group with lung involvement was younger than the other (Z=-2.40, P<0.05). However, there was no statistically significant difference in the illness duration (Z=-1.46, P>0.05) and pulmonary function between two groups (P>0.05). Conclusions Lobular hyperinflation, ground glass opacity and centrilobular nodules are the most common manifestations in LCH patients with lung involvement and the distribution is mostly diffuse. Nodules, cystic lesions and interlobular septa thickening may exist. Several signs may coexist simultaneously. Younger children with LCH are more vulnerable to lung involvement.

Objective: To investigate the mechanisms of curative effect of Tongxinluo capsule(通心络胶囊) on patients with coronary artery disease and angina pectoris.Methods: One hundred and twelve cases in accord with the diagnostic criteria of coronary heart disease of World Health Organization(WHO) were(randomly) divided into two groups: treatment group(n=60) and control group(n=52).The patients in both groups were treated with routine therapy including ?receptor retardant and ester of nitric acid etc.(Additionally),the treatment group was treated with Tongxinluo capsules,2 capsules each time and 2 times(per day) for 2 months consecutively.The clinical manifestations before and after treatment,the changes of(electrocardiogram)(ECG),microcirculation of nail bed and hemorrheology were observed in all the patients in both groups.Results: The total clinical effective rate and the rate of total improvement in ECG changes were 86.67% and 80.00% respectively after treatment in the treatment group,and compared with the control group(78.85% and 69.23%) the differences were significant(both P

OBJECTIVE: To investigate the available operation method of special type tracheobronchial foreign bodies removal. METHOD: Sixty one patients of special type tracheobronchial foreign bodies were extracted with some special instruments and methods depend on foreign body types. The features of operation on different kinds of foreign bodies were analyzed. RESULT: All patients were operated successfully by using foreign body hook (31 cases), pencil or writing screw brush extracted (11 cases), foreign body cage (13 cases), slender inverse claw esophagus foreign body clamp (3 cases) and so on. No complications and died cases were found. Only 5 patients were undertaken trachea incision before operation. CONCLUSION Suitable instruments and technique chose for every individual cases is the key to successful operation.

Objective:To grasp the distribution of fine antigenic epitope profiles of nucleoprotein (NP) and glycoprotein (GP) fragments of Crimean-Congo hemorrhagic fever virus (CCHFV) and to clarify the value of dominant antigenic epitopes in laboratory testing of Crimean-Congo hemorrhagic fever (CCHF).Methods:In a minimal synthetic short peptide consisting of 8 amino acids was segmentally expressed by CCHFV YL04057 strain using a modified bio-peptide synthesis method from 2014 to 2021 in the laboratory of Xinjiang University, College of Life Sciences. Using CCHFV polyclonal antibody or monoclonal antibody 14B7 (IgM) or CCHFV-positive sheep serum as antibodies, the minimal antigenic epitopes (BCEs) with antigenic activity on NP and GP fragments were identified by immunoblotting, and the obtained BCEs with sequence polymorphism were spatially clustered with CCHFV from different regions using the neighbor-joining method to determine the combination mode of BCEs with geographical correlation of regional distribution, to explore its application in establishing serological diagnosis. A prokaryotic expression plasmid (pET-32a), an E. coli expression plasmid (pGEX-KG) and a prokaryotic expression plasmid with an incomplete glutathione (GST188) tag (pXXGST-ST-1) were used to construct and express six dominant antigenic epitopes of different peptide lengths on NP fragments, and an indirect Enzyme-linked immunosorbent assay (ELISA) was established. CCHF sheep serum identified by immunofluorescence assay (IFA) was used as a control, and the specificity, sensitivity and overall compliance of the recombinant proteins with different peptide lengths of antigenic epitopes with IFA assay results were statistically analyzed. Results:CCHFV, NP and GP fragments had a total of 30 antigenically active BCEs, among which the core intermediate fragment NP2 (aa 170 th-305 th), which had a concentration of antigenic epitopes in the NP fragment, has 6 BCEs, and the NP1 (aa 1 st-200 th) and NP3 (aa 286 th-482 nd) at both ends have 9 BCEs; the Gc (aa 1 st-558 th) and Gn (aa 533 th-708 th) fragments of the GP fragment have 14 BCEs and a long antigenic peptide (AP) containing 15 amino acids, and the amino acid sequence homology of the NP fragment BCEs was 97.1% and that of the GP fragment BCEs was 89.1%. There was a significant difference ( P=0.0281, P<0.05). Among the 9 BCEs with sequence polymorphism in the GP fragment, 6 combined BCEs from GnEc1, GnE2, GnE4, GcE3, GcE6 and GcAP-4 (Ap) could cluster 15 CCHFV strains from different regions of the world into 5 geographical taxa, AsiaⅠ, AsiaⅡ, AficaⅠ, AficaⅡ and Europe. The constructs expressing PET-32a-NP (full length), PGEX-KG-NP2 (aa 170 th-305 th), pGEX-KG-NP2-1 (aa 235 th-275 th), PGEX-KG-NP2-1-1 (aa 237 th-256 th), pXXGST-1-NP2-1-2 (aa 250 th-265 th) and PGEX KG-NP2-1-3 (aa 260 th-276 th), six recombinant proteins CCHFV NP rabbit polyclonal antiserum (pAb) Western Blotting reaction positive, 33 sheep sera tested by IFA XHF as a reference, the sensitivity of the assay established by indirect ELISA using the recombinant proteins constructed from two fragments of NP2 and NP2-1 as antigens. The sensitivity, specificity and overall compliance were the best, with 73.4% (11/15) and 66.7% (10/15) for sensitivity, 100% (18/18) and 94.4% (17/18) for specificity, and 87.9% (29/33) and 81.8% (27/33) for overall compliance. Conclusion:CCHFV NP and GP are distributed with a high number of BCEs with antigenic immunoreactivity, among which the dominant antigenic epitopes are of high value in the laboratory serological diagnosis of CCHF.
