Artemisinin and its derivative is a kind of efficient,quick and low toxicity of anti-malarial drug.In recent years,we find that artemisinin drugs can not only against malaria,but also have pharmacological effects of immunosuppression,antiviral and anticancer.A number of studies have confirmed that artemisinin and its derivatives have the radiosensitization effects in nasopharyngeal carcinoma,cervical cancer,lung cancer and glioma,and their mechanisms are related to decreasing Weel protein expression,increasing Cyclin B1 protein expression,blocking G2-M phase and cell apoptosis.

Objective To observe the clinical effects and safety of scalp-body acupuncture and spine-manipulation therapy on preventively treating cervical cancer patients with postoperative urinary retention. Methods A total of 160 cases of cervical cancer patients with postoperative urinary retention were randomized into treatment group and control group, 80 cases in each group. Both groups were given conventional western medical treatment including preoperative indwelling of urethral catheter, clamping of urethral catheter 5 d after operation and release of the urine every 2-3 h, and trying to remove the urethral catheter 10-12 d after operation. Additionally, the treatment group received scalp acupuncture in the foot motor sensory area, body acupuncture of bilateral Shenshu (BL23) , Pangguangshu (BL28) , Ciliao (BL32) acupoints, and spine-manipulation therapy 5 d after operation. The clinical outcomes covered the incidence of urinary retention, residual urine volume, reset rate of catheter, and the clinical effect and safety in the two groups were evaluated. Results ( 1) The therapeutic effect of the treatment group was superior to that of the control group, and then the difference was significant (P<0.05). (2) After treatment, the incidence of urinary retention, residual urine volume, reset rate of catheter and average hospitalization days were less in the treatment group than those in the control group, the differences being significant ( P<0.05). ( 3) There was no adverse reaction during the treatment course. Conclusion Scalp acupuncture in the foot motor sensory area combined with body acupuncture and spine-manipulation therapy can promote the recovery of micturation function, and have satisfactory clinical effect and high safety in preventively treating cervical cancer with postoperative urinary retention.

Objective To explore the correlation of liver depression grading with estrogen receptor alpha and beta(ERα,ERβ)and G protein-couple receptor 30(GPR30)of the perimenopausal women suffering from non-organic insomnia. Methods A total of 127 perimenopausal women suffering from non-organic insomnia were enrolled into the study. The data collected by four diagnostic methods and the scores of Pittsburgh Sleep Quality Index(PSQI)were used for the scoring and grading of liver depression according to Syndrome Element Differentiation. The mRNA and protein expression levels of ERα,ERβand GPR30 in the mononuclear cells of peripheral blood from the patients were detected with real-time fluorescence quantitative polymerase chain reaction (RT-qPCR) and Western blot (WB)method respectively. Results (1)The differences of mRNA levels of ERα,ERβ and GPR30 were insignificant among the patients with different degrees of liver depression (P > 0.05). ERα mRNA/ERβ mRNA ratio was decreased with the increase of liver depression grading,the differences being significant (F = 6.710, P < 0.001). (2) The differences of protein levels of ERα, ERβ and GPR30 were insignificant among the patients with different degrees of liver depression (P > 0.05);ERα/ERβ protein gray value ratio was decreased with the increase of liver depression grading, and the differences were significant (P < 0.05) . Conclusion The decline of ERα/ERβ is probably contributed to the pathological basis of liver depression in perimenopausal non-organic insomnia women.

BACKGROUNDThe concept of minimally invasive techniques is to make every effort to reduce tissue damage. Certainly, reducing skin incision is an important part of these techniques. This study aimed to investigate the clinical feasibility of Mast Quadrant-assisted modified transforaminal lumbar interbody fusion (TLIF) with a small single posterior median incision.

METHODSDuring the period of March 2011 to March 2012, 34 patients with single-segment degenerative lumbar disease underwent the minimally invasive modified TLIF assisted by Mast Quadrant with a small single posterior median incision (single incision group). The cases in this group were compared to 37 patients with single-segment degenerative lumbar disease in the double incision group. The perioperative conditions of patients in these two groups were statistically analyzed and compared. The Oswestry Disability Index (ODI) scores, Visual Analog Scale (VAS) scores, and sacrospinalis muscle damage evaluation indicators before operation and 3, 12 months postoperation were compared.

RESULTSA total of 31 and 35 cases in the single incision and double incision groups, respectively, completed at least 12 months of systemic follow-up. The differences in perioperative conditions between the two groups were not statistically significant. The incision length of the single incision group was significantly shorter than that of the double incision group (P < 0.01). The ODI and VAS scores of patients in both groups improved significantly at 3 and 12 months postoperation. However, these two indicators at 3 and 12 months postoperation and the sacrospinalis muscle damage evaluation indicators at 3 months postoperation did not differ significantly between the two groups (P ≥ 0.05).

CONCLUSIONSMast Quadrant-assisted modified TLIF with a small single posterior median incision has excellent clinical feasibility compared to minimally invasive TLIF with a double paramedian incision.

Bronchial asthma is a kind of respiratory disease which affects people 's life quality seriously. Many factors in-volved in the occurrence and development of such disease, of which the aberrant expression of E-cad plays a critical role in it. Research found that E-cad is an important cell adhesion molecu-lar, and its main function is to maintain the structural integrity of cells and participate in the improvement of airway remodeling as well as restoration of immune function. Further study showed that the role of mucosal barrier of airway epithelial cells in bronchial asthma patients was often damaged. Moreover, the protein ex-pression of E-cad decreased significantly in mucosal molecular, which suggested that the abnormal expression of E-cad was in-volved in the development of bronchial asthma. A review on the relations between the abnormal expression of E-cad protein and bronchial asthma has been discussed in this paper, also it in-cludes the discussion about the mechanisms of E-cad’ s disorder-induced bronchial asthma as well as explores the strategies of bronchial asthma treatment, which may provide references for the follow-up research and clinical treatment.

Objective To observe the effect of Kidney-nourishing, Blood-activating, Phlegm-resolving and Resuscitation-inducing Decoction(KBPRD)on the expression of N-methyl-D-aspartate(NMDA)receptor subtype 1,2A,2B(NR1,NR2A,NR2B)in the cochlear spiral ganglion neurons(SGN)of tinnitus rats and to explore its mechanism, thus to provide experimental evidence for the treatment of tinnitus with KBPRD. Methods Sixty rats were randomly divided into normal group,model group,western medicine group,and low-,middle-,and high-dose Chinese medicine groups, 10 rats in each group. Rats were given intraperitoneal injection of sodium salicylate combined with water deprivation to induce tinnitus model. After successful establishment of the model, the rats in low-,middle-,and high-dose Chinese medicine groups were given gastric administration of KBPRD in the dosage of 5.5, 11, 22 g·kg-1·d-1 respectively, the rats in western medicine group were given gastric administration of 5 mg·kg-1·d-1 of carbamazepine,and rats in the model group and normal group were given gastric administration of 2 mL of normal saline,once every day,treatment time covering 8 weeks. The expression levels of NR1,NR2A,and NR2B in the cochlear SGN was detected by immunoblotting and real-time quantitative reverse transcription-polymerase chain reaction(qRT-PCR)after 8 weeks of treatment. Results Compared with the normal group,the expression levels of NR1, NR2A and NR2B in the model group were increased, the difference being significant (P < 0.05). Compared with the model group,the expression of NR1,NR2A and NR2B in low-,middle-,and high-dose Chinese medicine groups were significantly decreased(P<0.05).Conclusion KBPRD is effective on relieving tinnitus of rats, and its mechanism is correlated with lowering the increased expression of NR1,NR2A and NR2B in SGN of tinnitus rats.

BACKGROUNDUnstable pelvic fractures are complex and serious injuries. Selection of a fixation method for these fractures remains a challenging problem for orthopedic surgeons. This study aimed to compare the stability of Tile C pelvic fractures fixed with two iliosacral (IS) screws and minimally invasive adjustable plate (MIAP) combined with one IS screw.

METHODSThis study was a biomechanical experiment. Six embalmed specimens of the adult pelvis were used. The soft tissue was removed from the specimens, and the spines from the fourth lumbar vertebra to the proximal one-third of both femurs were retained. The pubic symphysis, bilateral sacroiliac joints and ligaments, bilateral hip joints, bilateral sacrotuberous ligaments, and bilateral sacrospinous ligaments were intact. Tile C pelvic fractures were made on the specimens. The symphysis pubis was fixed with a plate, and the fracture on the posterior pelvic ring was fixed with two kinds of internal fixation in turn. The specimens were placed in a biomechanical machine at a standing neutral posture. A cyclic vertical load of up to 500 N was applied, and displacement was recorded. Shifts in the fracture gap were measured by a grating displacement sensor.

STATISTICAL ANALYSIS USEDPaired-samples t-test.

RESULTSUnder the vertical load of 100, 200, 300, 400, and 500 N, the average displacement of the specimens fixed with MIAP combined with one IS screw was 0.46, 0.735, 1.377, 1.823, and 2.215 mm, respectively, which was significantly lower than that of specimens fixed with two IS screws under corresponding load (P < 0.05). Under the vertical load of 500 N, the shift in the fracture gap of specimens fixed with MIAP combined with one IS screw was 0.261 ± 0.095 mm, and that of specimens fixed with two IS screws was 0.809 ± 0.170 mm. The difference was significant (P < 0.05).

CONCLUSIONThe stability of Tile C pelvic fractures fixed with MIAP combined with one IS screw was better than that fixed with two IS screws.
