Objective To investigate the mechanism that mediates the inhibitory effect of Xinfeng Capsule(XFC)on interleukin(IL)-1β-induced impairment of chondrocytes.Methods XFC-medicated serum was collected from SD rats with XFC gavage,and its optimal concentration for chondrocyte treatment was determined using Cell Counting Kit-8 assay and flow cytometry.Dual luciferase reporter analysis was performed to analyze the targeting relationship between miR-502-5p and TRAF2.In cultured human chondrocytes induced with IL-1β,the effects of transfection with miR-502-5p inhibitor and XFC-medicated serum,alone or in combination,on expression levels of IL-1β,tumor necrosis factor-α(TNF-α),IL-4,and IL-10 were examined with ELISA,and the changes in the expressions of collagen type Ⅱ alpha 1(COL2A1),matrix metalloproteinase 13(MMP13),adisintegrin and metalloproteinase with thrombospondin motifs 5(ADAMTS5),and miR-502-5p/TRAF2/NF-κB axis gene expression were detected using RT-qPCR,Western blotting,and immunofluorescence assay.Results In cultured human chondrocytes,treatment with IL-1β significantly decreased the cell viability,increased cell apoptosis rate,lowered miR-502-5p,IL-4,IL-10,and COL2A1 expressions,and enhanced IL-1β,TNF-α,ADAMTS5,MMP13,TRAF2,and NF-κB p65 expressions(P<0.05),and these changes were significantly improved by treatment with XFC-medicated serum at the optimal concentration of 20％(P<0.05).Transfection of the chondrocytes with miR-502-5p inhibitor resulted in elevated expressions of IL-1β,TNF-α,ADAMTS5,MMP13,TRAF2,and NF-κB p65 and lowered expressions of miR-502-5p,IL-4,IL-10,and COL2A1,and XFC-medicated serum obviously reversed the effects of miR-502-5p inhibitor.Conclusion XFC can inhibit IL-1β-induced inflammatory response and ECM degradation in cultured human chondrocytes possibly by regulating the miR-502-5p/TRAF2/NF-κB axis.

Juvenile idiopathic arthritis (JIA)is a type of chronic rheumatism in children. It is mainly charac-terized by joint damage,accompanied by systemic symptoms and result in significant morbidity. The application of bio-logical agents has altered the traditional treatment pattern of JIA and significantly improved the condition of JIA pa-tients. JIA is a heterogeneous disease. Treatment recommendations issued by American College of Rheumatology(ACR) in 2011 have become an important reference for JIA treatment. There is a best response window for JIA treatment. Thus, the clinic application of biological agents should be used as soon as possible after the diagnosis of JIA. Meantime,it should be noted when a preparation is invalid,it need to use another possible biological agent in time to control disease progression.

OBJECTIVE:To preliminarily study the stability of 3 pieces of Chinese medicinal formula(CMF)after decoction, and provide reference for guaranteeing storage quality of decocted liquid and improving safety of drug use. METHODS:3 represen-tative formulas of Gegen Huangqin Huanglian decoction(A formula),Wuling powder(B formula)and Didang decoction(C for-mula)from Shanghan Zabing Lun were selected,the decocted liquid were stored under ambient temperature(25 ℃)and refrigerat-ed temperature (4 ℃) after decocting by automatic boiling-machine and packing. The microorganism,precipitation,pH and con-tents of total flavonoids,alkaloid,polysaccharide,total protein after 1,7,14,21,28 d were detected. RESULTS:Compared with the first day,contents of total flavonoids,polysaccharide in formula A at ambient temperature group were significantly in-creased on the 28th(P<0.05),content of polysaccharide in refrigerated temperature group was significantly increased(P<0.05). Content of polysaccharide in formula B at ambient temperature group was significantly decreased(P<0.05). The pH and content of total flavonoids in formula C at ambient temperature group and refrigerated temperature group were significantly increased (P<0.05 or P<0.01). Other indexes showed no obvious changes during the trial period. CONCLUSIONS:Under ambient temperature and refrigerated temperature,liquid ingredients of above decocted CMF will change when storing for 4 weeks. It indicates that the storage time of decocted CMF should not be more than 3 weeks.

OBJECTIVE: To investigate the efficacy and safety of NovaSure system for dysmenorrhea and abnormal uterine bleeding of adenomyosis.
 METHODS: A retrospective analysis on 30 patients with adenomyosis, who treated by NovaSure, were carried out. We collected related clinical data before operation and collected postoperative information about dyemenorrhea, menstruation, anemia and uterine volume by visiting outpatient or telephone.
 RESULTS: All patients were followed up for 7 to 31 months after the operation. The relief rate of menstrual pain was 83.3%. All patients got obvious improvements in menstruation and anemia (P<0.05). After operation, uterine volume was significantly decreased (P<0.05). Only one case received intervention in 2 years (3.3%).
 CONCLUSION NovaSure can relieve symptoms of menorrhagia and alleviate dysmenorrhea symptoms. It is a new way for the treatment of uterine adenomyosis.

Gestational trophoblastic tumors (GTTs) are malignant lesions that often cause abnormal genital bleeding and may present with hemoptysis, intraperitoneal bleeding or acute neurologic deficits. GTTs are generally highly chemosensitive with more favorable outcomes than other comparable malignancies. Here we report a rare case of invasive mole (FIGO stage IV, WHO score16) presenting with renal subcapsular hematoma due to bleeding renal metastasis. The patient had a pretreatment β-human chorionic gonadotrophin (β-HCG) level of 462 047 mIU/ml and received combined chemotherapy with etoposide, methotrexate, actinomycin-D, cyclophosphamide and vincristine with also adjuvant surgeries including hysterectomy and nephrectomy. The patient recovered well and the tumor has remained in complete remission for one year and a half.

BACKGROUNDHemifacial spasm (HFS) is a facial nerve disorder characterized by episodic involuntary ipsilateral facial muscle contraction. Information on Chinese patients with HFS has not been well-characterized. This study aimed to evaluate the clinical feature and the treatment status of HFS across China.

METHODSA cross-sectional study including 1003 primary HFS patients had been carried out in 15 movement disorder clinics in China in 2012. The investigated information was acquired from questionnaires and medical records including demographic data, site of onset, aggravating and relieving factors, treatments prior to the investigation, etc.

RESULTSIn this study, the ratio of male to female was 1.0:1.8, the mean age at onset was (46.6 ± 11.5) years. About 1.0% patients were bilaterally affected. The most often site of initial onset was the orbicularis oculi muscle. The most often affected sites were orbicularis oculi, zygomatic, and orbicularis oris muscles. Stress/anxiety and relaxation were most often aggravating and relieving factors, respectively; 2.3% patients had family history, 28.4% cases were combined with hypertension, and 1.4% patients were with trigeminal neuralgia. Botulinum toxin type A (BTX-A) injection was the most commonly used treatment, followed by acupuncture and oral medication. BTX-A maintained the highest repeat treatment ratio (68.7%), while 98.4% patients gave up acupuncture. The mean latency of BTX-A effect was (5.0 ± 4.7) days, the mean total duration of the effect was (19.5 ± 11.7) weeks, and 95.9% patients developed improvements no worse than moderate in both severity and function. The most common side effect was droopy mouth.

CONCLUSIONSThe onset age of HFS in China is earlier than that in western countries. The most often used two treatments are BTX-A injection and acupuncture, while the latter kept the poor repeat treatment ratio because of dissatisfactory therapeutic effect.
