Objective To report the results using endoscopic techniques in ce rvical discectomy and intervertebral fusion. Methods From October 2002 to August 2003, 26 patients underwent cervical discectomy and intervertebral fusion using endoscopic techniques. 16 patients had been followed-up more than 3 months, inc luding 4 females and 12 males. The average age was 53.2 years (range, 23 to 65 y ears). The disorders lasted from 3 to 14 months before surgery. There were 3 cas es of cervical injury associated cervical disc herniation (CDH), 8 of cervical s pondylotic myelopathy (CSM), 2 of solitary ossification of the posterior longitu dinal ligament (OPLL), and 3 of radiculopathy. The mean preoperative ADL of Japa nese Orthopedic Association (JOA) score was 7.2. The working channel was inserte d through a 2 cm long incision, the protruded discs or ossified posterior longit udinal ligaments were excised for complete decompression, then an appropriate in tervertebral PEEK fusion cage was implanted. Results All patients obtained endos copic cervical discectomy and interbody fusion successfully. None of cases was c onverted to open procedures. The surgery lasted an average of 120 min (range, 50 to 150 min), mean blood loss was 110 ml (range, from 40 to 140 ml). There was n o complication during operation and no any stimulating symptoms on laryngopharyn x after surgery. However, postoperative hemorrhage of the incision occurred in 1 case, then an injury of a thyroid vessel was found during immediate exploration . The follow-up period extended from 3 to 8 months (mean, 6.5 months), the aver age preoperative ADL of JOA score was 13.1 while the improvement rate was 60.2%. Conclusion The cervical discectomy and intervertebral fusion through endoscopi c approach is able to reduce the soft tissue injury and the incidence of stimula ting symptoms on laryngopharynx, which makes the surgery more safe. The indicati ons for this procedure include cervical disc herniation, cervical myelopathy, ra diculopathy, and traumatic cervical disc injury on C3,4 to C5,6 segments.

Background The mitochondrial Na+/Ca2+exchanger, NCLX, plays an important role in the balance between Ca2+influx and efflux across the mitochondrial inner membrane in endothelial cells. Mitochondrial metabolism is likely to be affected by the activity of NCLX because Ca2+activates several enzymes of the Krebs cycle. It is currently believed that mitochondria are not only centers of energy produc-tion but are also important sites of reactive oxygen species (ROS) generation and nucleotide-binding oligomerization domain receptor 3 (NLRP3) inflammasome activation. Methods&Results This study focused on NCLX function, in rat aortic endothelial cells (RAECs), induced by glucose. First, we detected an increase in NCLX expression in the endothelia of rats with diabetes mellitus, which was induced by an injection of streptozotocin. Next, colocalization of NCLX expression and mitochondria was detected using confocal analysis. Suppression of NCLX expression, using an siRNA construct (siNCLX), enhanced mitochondrial Ca2+influx and blocked efflux induced by glucose. Un-expectedly, silencing of NCLX expression induced increased ROS generation and NLRP3 inflammasome activation. Conclusions These findings suggest that NCLX affects glucose-dependent mitochondrial Ca2+signaling, thereby regulating ROS generation and NLRP3 in-flammasome activation in high glucose conditions. In the early stages of high glucose stimulation, NCLX expression increases to compensate in order to self-protect mitochondrial maintenance, stability, and function in endothelial cells.

Objective To investigate the role of interleukin-27 (IL-27) in proliferation and differentiation of CD4+ T cells in ankylosing spondylitis(AS).Methods CD4+ T cells were separated from peripheral blood which collected from AS patients and health controls(HCs).Cells proliferation was detected by CCK-8 kit,and cytokines were analyzed by ELISA.Real-time PCR was used to determine the mRNA expression of T-bet and GATA3.Results Serum IL-27 level in patients with AS was obviously higher than that in HCs(P ＜0.01).The proliferation rate of CD4+ T cells and the level of IFN-γin cultured medium in AS were higher than those in HCs group after IL-27 stimulation (P ＜ 0.01).IL-27 could induce T-bet mRNA expression in CD4+ T cells in AS (t =14.3,P ＜ 0.01),but no change was found in GATA3 mRNA expression.Conclusions IL-27 could induce the proliferation of CD4+ T cells and the activation of T-bet pathway in AS.Furthermore,Th1 immune response and related cytokines could be induced by IL-27 in AS.These implicate that IL-27 may play an important role in AS related inflammation.

Objective To analyze the epidemic characteristics of multidrug-resistant tuberculosis(MDR-TB)in Hunan Province from 2013 to 2016,and provide theoretical basis for the prevention and control of tuberculosis.Methods Information about TB patients in Hunan Province reported by China Information System for Disease Control and Prevention between January 2013 and December 2016 was analyzed retrospectively.Results From 2013 to 2016,the total drug resistance registration rate in Hunan Province was 5.53/million(1 496/270 330 000),multidrug registration rate was 5.40/million(1 459/270 330 000),drug resistance rate and multidrug resistance rate showed an upward trends(trend x2 =113.605,96.590,respectively,both P<0.001).Among MDR-TB patients,male were more than females(74.09%vs 25.91%),most were more than 25 years of age,especially 45～age group(27.07%);the proportion of patients with MDR-TB retreatment was higher than that of the initial treatment(69.91%vs 30.09%).From 2013 to 2016,distribution range of MDR registration rates in different regions were 4.07/million-7.23/million.Conclusion MDR-TB in Hunan Province in 2013-2016 is increasing year by year,and mainly concentrate on young people over 20 years old.There are more cases of male and retreatment;it is necessary to strengthen regular treatment and prevention of key population,enhance the ability to identify and diagnose MDR-TB patients,and reduce the spread of MDR-TB.
