Objective To investigate the clinical efficacy of TongluoShu Liquid in treating rheumatoid arthritis at early stage. Methods 100 cases were randomly recruited into a control group and a treatment group with 50 cases in each group. The treatment group was given TongluoShu liquid, 150ml / time, twice a day; and the control group was given Diclofenac Sodium Sustained Release Tablets (Deegan), one granule for each time, twice a day, and Methotrexate 7.5mg / time, once per week. Results In the treatment group, symptoms, signs and biochemical indicators were significantly improved, and the swelling of the soft tissue around the joints in stage Ⅰ and Ⅱ were also reduced. Besides, osteoporosis was controlled and the progress of destruction to the cartilage of stage Ⅲ was detained, though there was no statistical difference between the two groups after the treatment. Conclusion ShuTongluo liquid is a safe and effective medicine with less adverse reactions in treating rheumatoid arthritis.

Objective: To explore the treatment outcome of triangular osteosynthesis (TOS) for the treatment of unilateral Isler type II lumbosacral junction injuries (LSJIs). Methods: Data of sixteen patients with unilateral Isler type II LSJIs surgically who were treated in our Hospital from March 2015 to February 2017 were retrospectively analyzed. There were 13 males and 3 females with an average age of 35.5 years (range, 24-61 years). Seven patients were multiple injuries including head, thoracic, musculoskeletal and nerve injuries. According to Isler classification of LSJIs, there were 5 cases of type IIa, 9 of type IIb and 2 of type IIc. All the LSJIs combined with ipsilateral sacral fractures. The sacral fractures were classified by Denis classification with 1 case of zone I, 13 cases of zone II and 2 cases of zone III. According to Tile classification of pelvic fractures, there were 3 cases of type B2, 11 of type C1 and 2 of type C3. There were 3 cases combined with sacral nerve injury among which there were 2 cases of grade II and 1 case of grade III according to Gibbons classification of neurologic deficits. All cases were surgically treated with triangular osteosynthesis. There were 14 cases combined with iliosacral screws fixation in S₁ and 2 cases combined with posterior locking plates. Results: All patients were followed up for 20.6 months (range, 16-30 months). CT scan was conducted 12 to 24 months after surgery which showed all the sacral fractures were union, and 2 cases achieved bony fusion in L₅S₁ facets while the other 14 didn’t. According to Majeed’s pelvic injury evaluation, clinical outcomes were rated with excellent in 12 cases, good in 2 cases, fair in 2 cases. The excellent and good rate was 87.5% (14/16) . According to Mears-Velyvis evaluation criterion, there were 14 cases with anatomical reduction and 2 cases with satisfactory reduction. Among the 3 cases with sacral nerve injury, 2 cases were improved from Gibbons grade II to grade I and the other 1 case was improved from Gibbons grade III to grade II, still feeling numbness on the lateral foot. There were no intraoperative complications in all patients such as neurovascular injuries. No incision infection, fat liquefaction and other incision related complications occurred postoperatively. Irritation and pain in iliac spine about prominent implant occurred in 1 case and lumboscaral stiffness in 1 case, in which the symptom relieved and disappeared after implants removal. Conclusion Triangular osteosynthesis can provide enough stabilization for Isler type II LSJIs and achieve satisfactory outcomes.

Objectives: To explore the expression regulation of type 1 and type 2 (Th1 and Th2) cytokines from serum of coal miners and the evaluation in surveillance of coal workers' pneumoconiosis, 630 coal miners were studied. Methods: A total of 90 male patients diagnosed as coal workers' pneumoconiosis (CWP) in a institute for occupational health and 19 male workers newly diagnosed as CWP patients was chosen as CWP group with simple random sampling method from a coal mine group from January 2013 to December in 2015. 180 male coal miners with abnormal but not diagnosed as CWP were selected as CWP suspected group with simple random sampling methods, meanwhile 180 male coal miners with normal chest X-ray photograph was as dust-exposed group by 1∶1 matched as age. And 161 healthy males accepted pre-employed examination were selected as control group, CWP suspected group, dust-exposed group and control group called as non-CWP group. According to screening test and diagnosis test, the basic information and occupational history of all subjects were collected, and cytokines including IL-1β, IL-8, IFN-γ, IL-6 and IL-10 of serum were detected. Receiver operator characteristic (ROC) curve was used to determine the optimal cutoff value of each cytokine. Area under curve (AUC), the validity and reliability were calculated and judged. Results: The average age of control group, dust-exposed group, CWP suspected group and CWP group were (27.4±5.0) , (43.4±10.7) , (48.2±6.2) , (64.7±7.0) years old, respectively. The median level of IL-1β, IL-8, IFN-γ and IL-6 in cases group (1 638.30, 2 099.49, 815.18,140.32 pg/ml) were higher than that of non-cases group (1 445.57, 1 402.26, 736.38, 95.73 pg/ml) (P<0.05) . The level of IL-8 (1 503.99 pg/ml) in CWP suspected group was higher than that of control group (1 295.67 pg/ml) and dust-exposed group (1 376.94 pg/ml) , but the level of IL-10 (654.08 pg/ml) was lower than that of control group (596.64 pg/ml) . The ratio of IFN-γ/IL-6 ranged from 5 to 8, and the ratio in CWP group (5.87) was lower than that of non-CWP group (7.61) . The IL-6 and IL-8 among the subjects of dust-exposed group in terms of the age distribution of among had reached statistical significance. According to ROC, the cutoff value of IL-1β, IL-6, IL-8, IL-10 and INF-γ reached 1 582.65, 116.53, 1 791.54, 581.08 and 792.69 pg/ml, respectively. The AUC was 0.668, 0.895, 0.859, 0.716 and 0.637, respectively. It was found that IL-6 and IL-8 could be used as biomarkers in detecting CWP, the sensitivity and specificity was 82.6% and 84.6%, 78.0% and 84.8%, respectively; Youden's index was 0.674 and 0.628 and the consistency rate was 84.3% and 83.7%, while Kappa value was 0.55 and 0.52. Conclusion There was Type 1 and type 2 cytokine dysregulation in CWP patients. IL-6 and IL-8 can be used as effective biomarkers to forecast lung injury before X-ray changes.
