OBJECTIVETo compare the efficacy differences between needle-knife therapy and acupuncture-cupping for treatment of cervical spondylosis (CS) of cervical type.

METHODSSixty cases of CS were randomly divided into a needle-knife group (30 cases) and an acupuncture-cupping group (30 cases). The needle-knife therapy was applied at points among superior nuchal line of occipital bone, bilateral neck muscle, neck centerline, trapezius and medial border scapula for only once. In the acupuncture-cupping group, acupuncture was applied at Fengchi (GB 20), Fengfu (GV 16), Tianzhu (BL 10), Dazhui (GV 14), Jianjing (GB 21), Jiaji (Ex-B2, from C4 to C6), Houxi (SI 3) and Ashi point, followed by cupping on local skin, once every other day for totally six times. The score of neck stiffness and visual analogue scale (VAS) were observed before and after treatment, in follow-up of 1, 3 and 6 months after treatment in the two groups, and the efficacy was compared.

RESULTSIn the needle-knife group, 9 cases were cured, 12 cases were markedly effective, 8 cases were effective and 1 case was failed; the total effective rate was 96.7% (29/30) and the cured and markedly effective rate was 70.0% (21/30). In the acupuncture-cupping group, 8 cases were cured, 9 cases were markedly effective, 11 cases were effective and 2 cases were failed; the total effective rate was 93.3% (28/30) and the cured and markedly effective rate was 56.7% (17/30). The difference of total effective rate in the two groups was not statistically significant (P > 0.05), but the cured and markedly effective rate of needle-knife group was significantly superior to that of acupuncture-cupping group (P < 0.05). The needle-knife therapy was significantly superior to acupuncture-cupping on improvement of neck stiffness in the follow-up of 1, 3, 6 months after treatment (P < 0.05, P < 0.001); both treatments were effective on relief of neck pain, but the needle-knife group had better effects in the follow-up of 3 and 6 months after treatment compared with acupuncture-cupping group (both P < 0.01).

CONCLUSIONThe needle-knife therapy has better effects on neck stiffness and pain relief than acupuncture-cupping, and it is more treatment time saving.

Based on the research of risk assessment of medical equipment safety and operation to formulate evaluation criteria and methods of how to use the practical management work. Objective to evaluate the practical method is to use and the risk of adverse events of medical equipment in operation risk in order to find the risk, control risk, ensure safety in time, so that Improve the level of risk management of medical equipment.

Clustered regulatory interspaced short palindromic repeats (CRISPR) found in bacteria and archaea genome that contains multiple short repeats loci, provides acquired immunity against invading foreign DNA via RNA-guided DNA cleavage. The first inkling of this hot new genetic engineering tool turned up in 1987, when a research team observed an oddly repetitive sequence at one end of a bacterial gene. Now three types of CRISPR/Cas system have been identified: types I, II and III. In the type II CRISPR/Cas9 system, short segments of foreign DNA termed 'spacers' are integrated within the CRISPR genomic loci, transcribed and processed into short CRISPR RNA (crRNA). These crRNAs anneal to trans-activating crRNA (tracrRNA) and direct sequence-specific cleavage in that a double-strand break (DSB) is generated by Cas proteins. Based on these findings, various genetic methods, including gene targeting (Gene disruption), gene insertion, gene correction etc., are being designed to manipulate the genomes of different species at specific loci. Compared with zinc finger nucleases (ZFN) and transcription activator-like effector nucleases (TALEN), CRISPR/Cas9 is simpler with higher specificity and less toxicity. This review summarizes recent progress, discusses the prospects of CRISPR/Cas9 system, with an emphasis on its structure, principle, applications and potential challenges, and provides a useful reference for researchers who are interested in this new technique.

Multimedia teaching was not often used in pediatric surgery teaching in department of pediatrics.We used multimedia courseware to assist teaching in clinical teaching for 2007 grade seven-year-program students in Chongqing medical university.Results showed that this method improved students' learning enthusiasm,initiative and interests and laid a good foundation for the smooth development of their clinical practice.

Objective To explore the characteristics of approach and avoidance behaviors among subthreshold depressed adolescents. Methods 27 subthreshold depressed adolescents and 29 healthy con?trol teenagers completed the approach?avoidance task,and the reaction time at approach and avoidance task of the two groups was compared. At the same time,their differences were analyzed between the two groups on the Behavioral Inhibition/Activation System Scale scores. Results ( 1 ) Subthreshold depression group (1208.18±338.92)ms) had significantly longer reaction time than those in healthy control group((1058.40 ±204.22)ms) when approaching happy expression ( t=2.02, P<0.05). (2) Subthreshold depression group (37.33±4.46) had significantly lower behavioral activation system scale scores than those in healthy control group ((39.76±3.75), t=-2.21, P<0.05); and the score of reward responsiveness was marginally signifi?cant lower in subthreshold depression group (12.63±1.67) than that in healthy control group ((13.41± 1.30), t=-1.97, P=0.054). Conclusion To activate the approach behaviors of subthreshold depression adolescents may be helpful for reducing the symptoms of depression.

Subcortical ischemic vascular dementia is a subtype of vascular cognitive impairment. Its major pathological features are lacunar infarcts and deep white matter changes, and its major clinical manifestation is executive function impairment. Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) provides an opportunity for the study of pure subcorticai ischemic vascular dementia in the absence of Alzheimer's disease. There is currently lack of the gold standard for diagnosing subcortical ischemic vascular dementia. Imaging examination plays an important role in its diagnosis, while the treatment must first consider the control of vascular risk factors, especially hypertension.

The plasma levels of atrial natriuretic factor (ANF), angiotension II (AII, vaso-pressin (VP) and endogenous digitalis-like factor (EDLF) were determined in 23 patients with mi-tral stenosis before and after percutaneous balloon mitral valvuloplasty (PBMV). Before PBMV, the plasma levels of ANF and EDLF were elevated in all patients with lower level of All than nor-mal. After the procedure, with a concomitant decrease of left atrial pressure, the plasma ANF de-creased at 15 minutes (from 317. 4?96. 2 to 164. 9?56. 8ng/L , P

Focal adhesion kinase (FAK), a type of protein tyrosine kinase in the cytoplasm, is highly expressed in many types of malignant tumors. FAK is named as such because of its close relationship with the cell adhesion function. Recent studies show that FAK is expressed in many tumor cells and has a definite relationship with cancer progress, metastasis, and prognosis. Accordingly, FAK has become one of the new tumor therapeutic targets that will bring new methods for tumor therapy.
