OBJECTIVE: To investigate clinical effects of intraoperative arthrography monitoring assisted closed reduction and internal fixation for intercondylar fracture of humerus in children. METHODS: From January 2013 to July 2018, 18 children with intercondylar fracture of humerus were treated by operation, including 13 males and 5 females aged from 3 to 12 years old with an average age of (8.50±2.57) years old. According to Toniolo & Wilkinson classification, 8 children were typeⅠand 10 children were typeⅡ. During the operation, closed reduction and internal fixation were performed under the monitoring of intraoperative radiography, open reduction and internal fixation were performed in necessity. Mayo score of elbow joint was used to evaluate clinical effect at 6 months after operation. RESULTS: All children were underwent arthrography monitoring during operation, 5 children were treated with closed reduction and internal fixation for intraoperative arthrography found no fracture of articular cartilage, 11 children by closed reduction and internal fixation because of fracture of articular cartilage involving the joint space with displacement less than 2 mm, and 2 children by closed or open reduction and internal fixation for fracture of articular cartilage surface with displacement above 2 mm, which 1 child with smooth of joint surface was performed closed reduction and internal fixation, 1 child without smooth of joint surface and displacement above 2 mm was performed open reduction and internal fixation. All children were followed up from 8 to 26 months with an average of (20.28±4.40) months. All factures were healed from 6 to 9 weeks with an average of (7.33±0.77) weeks. Postoperative Mayo score of elbowjoint at 6 months was (89.44±11.36), and 12 patients got excellent results, 5 good and 1 poor. One patient occurred partial limitation of flexion or extension of elbow joint. No elbow deformity and other complications occurred. CONCLUSION The treatment of intercondylar fracture of humerus in children under monitoring of intraoperative radiography could reduce opertaion injuries and complications, confirm the reduction effect of articular surface of cartilage in time and clearly, and promote recovery of elbow joint function.

OBJECTIVE: To study the protective effects of ginkgo biloba extract on the right ventricular hypertrophy. METHODS: Seventy-two SD male rats were randomly divided into 3 groups: control group(CON), monocrotaline-induced right ventricular hypertrophy group (MCT) and ginkgo biloba extract treated group (EGB) (n=24 in each group). Group MCT and group EGB were intraperitoneally injected with 2%MCT at the dose of 60 mg /kg on the first day. From the second day, group MCT was injected with 2 ml 0.9% sodium chloride, and 60 mg/kg ginkgo leaf extract was administered to the stomach in group EGB. The control group was injected with 2 ml 0.9% sodium chloride on the first day. After 3 weeks, in each group,cardiac hemodynamic changes were measured, heart weight index was calculated, and myocardial pathological changes were observed by HE staining. The expression of TRPC6 was detected by real-time polymerase chain reaction (real-time -PCR) and Western blot. RESULTS: Compared with the control group, the right ventricular systolic pressure (RVSP) was increased significantly in the MCT group(P＜0.01), the maximum or decline rate of descent (RV ±dp/dt) of the right ventricle pressure was increased significantly(P＜0.01), while the EGB group had the same trend as all the indexes in the group MCT, but the amplitude of all indicators in group EGB were decreased significantly than those of group MCT(P＜0.01), and the right ventricular hypertrophy index (RVMI) in group EGB was significantly lower than that in group MCT(P＜0.01).Group MCT showed typical myocardial hypertrophy performance by HE staining, and the right ventricular myocytes in group EGB were significantly improved than that in group MCT, and the mRNA and protein expression levels of TRPC6 in the right ventricle of group MCT and group EGB were increased(P＜0.01), while the EGB group was significantly lower than that of the MCT group(P＜0.01). CONCLUSION Ginkgo biloba extract may inhibit the signal pathway of CaN / NFAT in cardiac myocytes by reducing the expression of TRPC6 protein, and then play an early protective effect on myocardial hypertrophy.

This study was designed to evaluate the anti-inflammatory effect of recombinant human kallistatin (Kal) on ulcerative colitis (UC) in the mouse model. Acute colitis was induced by administration of 4% dextran sodium suffate (DSS) to KM mice for 7 days. The mice were then randomized into 5 groups:model control, Kal 0.2 mg·kg^-1·d^-1, 1.0 mg·kg^-1·d^-1 and 2.0 mg·kg^-1·d^-1 group, salazosulfapyridine (SASP) group. Ten age-matched normal KM mouse were administered with saline in the normal control. The weight, colon length, inflammation factor (MPO/SOD/MDA) and TNF-α/IL-10 levels among the five groups of mice were determined. The results showed that histological index score and MPO/MDA/TNF-α levels of high-dose Kal treatment group and SASP group were significantly lower compared with the model group (P<0.01), but the weight, colon length, IL-10 level and SOD activity were significant higher than the model group (P<0.01), approaching the normal group. These parameters showed that Kal can significantly relieve the UC state in a dose-dependent manner. This study demonstrates that Kal significantly remits UC in mice, and participates in the regulation of inflammatory cytokines TNF-α/IL-10 levels and has some antioxidant activity.

Objective:To observe the clinical efficacy of modified Shenling Baizhu San combined with thyroxine tablets in the treatment of Hashimoto's thyroiditis (HT). Method:The 68 patients with HT were randomly divided into treatment group and control group, with 34 patients in each group. Control group was treated with thyroxine tablets alone, while treatment group was treated with modified Shenling Baizhu San in addition to the therapy of control group. Free triiodothyronine (FT₃), free Thyroxine (FT₄), thyroid stimulating hormone (TSH), serum thyroid peroxidase antibody (TPOAb) and thyroglobulin were observed before and after treatment in the two groups of HT patients. The changes of thyroglobulin antibody (TgAb) and traditional Chinese medicine (TCM) syndrome score, and the safety of TCM prescription were observed. Result:After 3 months of treatment, the effective rate of treatment group was 91.2%, which was significantly higher than 70.6% of control group, with statistically significant difference (P<0.05); after 3 months of treatment, the scores of TCM syndromes in two groups were significantly lower than those before treatment (P<0.05), and the scores of TCM syndromes in treatment group were significantly lower than those in control group (P<0.05). FT₃ and FT₄ in treatment group and control group increased significantly after 3 months of treatment (P<0.01), but treatment group increased more significantly than control group (P<0.01); TSH, TgAb and TPOAb in treatment group and control group decreased significantly after 3 months of treatment (P<0.05), and treatment group decreased more significantly than before treatment (P<0.05), with no adverse reaction during the treatment. Conclusion:Modified Shenling Baizhu San combined with thyroxine tablets in the treatment of HT is more effective than simple thyroxine tablets, which is worthy of further clinical and experimental study.

OBJECTIVETo study the expression of P57(kip2) and Maspin in the pathological scar and their possible role in the pathogenesis of abnormal scars.

METHODSImmunohistochemistry integrated image analysis and reverse transcription polymerase chain reaction (RT-RCR) were performed to detect the expression of P57(kip2) and Maspin in hypertrophic scar, keloid, mature scar and normal skin. Statistics was used to analyze the datas.

RESULTSThe expression of P57(kip2) protein was fixed to fibroblast intranuclear in abnormal scar, and the expression of P57(kip2) protein and P57(kip2) mRNA decreased (P < 0.05). The expression of Maspin protein was fixed to fibroblast cytoplasm and intranuclear in abnormal scar, and the expression of Maspin protein and Maspin mRNA decrease, compared with that in normal group (P < 0.05). There was positive correlation between P57(kip2) protein and Maspin protein expression (P < 0.01).

CONCLUSIONSThe decreased expression of P57(kip2) and Maspin in abnormal scar shows that they are cicatrix-related genes. There is a positive relationship between the two genes. It may be one of the mechanisms of pathogenesis of abnormal scar. It makes effect through fibroblasts.

To explore the effect of digital breast tomosynthesis (DBT) on the classification of breast imaging-reporting and data system (BI-RADS) and its significance.
 Methods: A total of 832 patients with breast diseases, who came from Second Clinical College of Fujian Medical University from May 2013 to November 2013, were collected. The patients were examined by double position radiography (including craniocaudol and mediolateral oblique) and COMBO mode [including DBT and full-field digital mammography (FFDM)]. Meanwhile, the results of FFDM and DBT were classified. The number of glands, the characteristics of mass and other indirect signs were compared by COMBO and FFDM modes. Paired Wilcoxon rank sum text was adopted to investigate the differences between COMBO mode and FFDM mode in the 832 patients, and receiver operator characteristic curve (ROC) was applied to analyze the 79 patients with the pathological results.
 Results: The patients with large amount of glands (including Class c and Class d) accounted for 87.6% in the 832 patients, while the patients with small amounts of glands (including Class a and Class b) accounted for 11.7%. In estimating the content of glands, more details about the distribution of glands were found in the COMBO mode compared with those in the FFDM mode. According to the results of paired Wilcoxon rank sum test, there was significant statistical difference in BI-RADS classcification in breast masses between the COMBO mode and the FFDM mode (P<0.05), though the overall classification of the COMBO mode is higher than that of the FFDM mode. The pathology was served as a standard to estimate the diagnostic efficiency. The area under ROC curve was 0.805 in the FFDM mode, while that in the COMBO mode was 0.941. The optimal sensibility in the COMBO mode was 82.9%, which was higher than that in the FFDM mode. However, the specificity was 93.2% in both COMBO mode and the FFDM mode.
 Conclusion: DBT has a high clinical significance in BI-RADS classification for breast X-ray examination.
