MicroRNAs(miRNAs) are a class of highly conserved,endogenous,small,non-coding RNAs that reg-ulate RNAi and are key regulators of tumorigenesis and development.miR-338 is abnormally expressed in most tumors. Aberrant expression of miR-338 can affect the proliferation, invasion, metastasis, angiogenesis and other physiological activities of tumor cells and play a vital role in the regulation on one or more target-genes.

BACKGROUND:There is no literature about the treatment according to the mechanism of cervical spine injury classification, especial y for the treatment of extension type cervical fracture/dislocation with merger cases of posterior composite structure damage, whether simple anterior approach can meet the needs of the treatment has no detailed elaboration. This article may analyze from the aspect of cervical spine injury mechanism. OBJECTIVE:To observe the short-term effect of anterior cervical Cage-assisted fusion combined with locking titanium plate internal fixation for the treatment of extension type cervical fracture. METHODS:A retrospective analysis was performed in 15 extension type cervical spine fracture dislocation patients treated with decompression anterior cervical intervertebral disc resection plus bone graft with cage-fusion locking titanium plate internal fixation from June 2006 to March 2011 in the Department of Orthopedics, Xianning Central Hospital, including 10 cases of single segment injury and treatment, and five cases of multiple segment injury and treatment. Japanese Orthopaedic Association score and the neck disability index were compared before and after treatment;the cervical flexion and height were measured according to the antersposterior X-ray film taken before fixation, 1 week after fixation and final fol ow-up.RESULTS AND CONCLUSION:The patients were fol owed-up for 8-37 months. One case had Cage mild sinking and shift, and there was no internal fixation breakage or loosening in al the patients. Transient pharyngeal discomfort was observed in 11 patients. Compared with the preoperation, the Japanese Orthopaedic Association score, neck dysfunction index, fusion segment cervical flexion and fusion segment intervertebral disc height were significantly improved at 1 week after fixation and final fol ow-up (P<0.05). There were no significant differences between 1 week after fixation and final fol ow-up (P>0.05). The short-term effect of decompression anterior cervical intervertebral disc resection plus bone graft with cage-fusion locking titanium plate internal fixation for the treatment of extension-type cervical fracture is good.

With patients' general situation, medication use, occurrence time of adverse drug reaction/event (ADR/ADE), clinical manifestations and prognosis as reference items, a retrospective study was made for 315 cases with ADR/ADE induced by Gastrodin in Chongqing from January 2008 to June 2014, in order to analyze the characteristics of ADR/ADE and provide reference for rational clinical medication. The results showed that among the 315 cases with ADR/ADE, 143 cases (45.4%) were males and 172 cases (54.6%) were females, most of them (74.9%) were aged above 45; 60 cases (19.0%) with ADE were caused by off-label indications and 66 cases (21.0%) with ADE were caused by over dosage; ADR/ADE cases induced by intravenous drip mainly happened within 30 min (85.5%), ADR/ADE cases induced by oral administration mainly happened within 2 h (74.4%), and all of ADR/ ADE cases induced by intramuscular injection happened within 10 min. Totally 593 ADR/ADE cases were reported, which were mainly damages in gastrointestinal system, skin and its adnexa; And 61.9% of ADR/ADE cases were newly reported. It is suggested that medical workers shall learn about the regularity and characteristics of ADR/ADE induced by gastrodin, apply it in clinic with standards, pay close attention to changes of patients' situations and attach importance to the monitoring of ADR/ADE, so as to enhance the safety of medication.

Objective To establish an experimental subarachnoid hemorrhage(SAH)model with endo- cerebrovascular peroration.Method The right external carotid artery of SD rats were isolated,leaving a stump of approximately 3 to 4 mm.A-3-O monofilament nylon suture was inserted up through the stump of external carotid artery to the internal carotid artery for about 18~19 mm.A small resistance was usually felt,and the suture was then advanced 2 mm further and the suture was immediately withdrawn.Two hours or two days after SAH induction,SAH extension was observed.Two days after SAH induction,the diameter of the basilar artery was measured.Results SAH extends from the ipsilateral artery to the eontralateral artery after SAH induction.The diameters of basilar arteries in SAH animals were smaller than those of control rats,indicating the present of cerebrovascular spasm in SAH animals.Conclusions The endo-cerebrovascular perforation technique for establishing a non-craniotomy SAH model is reliable.

Objective To observe the clinical efficacy of long-snake moxibustion in treating asthma due to deficiency of lung and spleen. Method Seventy patients were randomized into a treatment group and a control group. The treatment group was intervened by using long-snake moxibustion, while the control group was by regular acupuncture treatment. The therapeutic efficacy was evaluated after 1-month treatment. Result In the treatment group, 22 subjects showed marked efficacy, 27 showed effective, 6 failed, and the total effective rate was 89.1%; in the control group, 18 subjects showed marked efficacy, 25 showed effective, 12 failed, and the total effective rate was 78.2%. The therapeutic efficacy of the treatment group was significantly higher than that of the acupuncture group(P<0.05). Conclusion Long-snake moxibustion can produce a higher therapeutic efficacy than regular acupuncture in treating asthma due to deficiency of lung and spleen.

OBJECTIVE:
Dynamic observation of Epstein-Barr virus (EBV) DNA load before and after the treatment in patients with Nasopharyngeal carcinoma (NPC), predicting the incidence of distant metastasis and offering more personalised choice of therapies.
METHOD:
Fifty-four cases of patients with NPC were taken by fluorescence quantitative PCR assay of EBV DNA load before and after the treatment, all patients were followed up according to plan and carried out the progression-free survival (PFS) and overall survival (OS).
RESULT:
EBV DNA load in plasma of patients with NPC can partly reflect the clinical characteristics of patients; EBV DNA load in some patients with distant metastasis was higher than those patients with continuous remission when they were not started treatment (P < 0.05); For those patients whose EBV DNA copies were lower than 20,000 copies/mI before the treatment, the progression-free survival and overall survival rates were higher than those high expression patients, and the difference were statistically significant (PF < 0.01 and P < 0.05).
CONCLUSION
The EBV DNA load in the plasma of NPC patients can partly predict the occurrence of distant metastases before treatment.
