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.

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 evaluate the effect of hyperuricemia on vascular complications of type 2 diabetes and analysis of the possible mechanism. Methods 586 cases with T2DM were divided into two groups: normal serum uric acid (n=397) and hyperuricemia (n=189).The morbidity of macrovascular and microvascular complications and the serum levels of CRP,TNF,IL-1,IL-2,IL-6,IL-8 and PAI-1 were detected. Results (1)Hyperuricemia group showed higher BMI, blood pressure, TG,TC,LDL,WHR ratio and lower serum HDL-C than the group with normal uric acid (all P<0.05).(2)Group with hyperuricemia showed higher morbidities of macrovascular and microvascular complications than the group with normal uric acid (all P<0.05).(3) Group with hyperuricemia had higher levels of CRP,TNF,IL-6,IL-8,PAI-1 (all P<0.05). Conclusions (1) Hyperuricemia is associated with obesity and dyslipidemia.(2) Hyperuricemia may cause atherosclerosis by inflammation of vascular endothelium, resulting macrovascular and microvascular complications.

Objective Identifying the factors of psychological pressure from medical disputes on clinical doctors and possible solutions. Methods Self-rating Anxiety Scale (SAS) and the Occupational Stress Indicator (OSI) were called into play, to study 52 clinical doctors in a tertiary hospital in a city, who had encountered medical disputes in recent two years. In parallel, 63 clinical doctors without such disputes and 50 non-clinical workers were randomly selected as the control group for questionnaires. Results Clinical doctors with such an experience were commonly found to be anxious, and their SAS score (58. 27±11.38)averaged higher than those in the control group. Doctor-patient relationship, legal liabilities and clinical positions were found to be positively correlated to psychological pressure of clinical doctors. Conclusions Medical disputes tend to add to psychological pressure of the doctors. Clinical doctors deserve psychological counseling and training and improvement of their working conditions.

Objective To investigate the expressions of COX-2 and VEGF-C in breast carcinoma and their correlation with lymphangiogenesis and lymph node metastasis. Methods The expressions of COX-2 and VEGF-C and D2-40 were evaluated in 46 cases of breast carcinoma by immunohistochemical staining SP methods. The lymphatic vessels density (LVD) in tumor was counted through the special marker D2-40. Results The positive rate of COX-2 and of VEGF-C was 73.91% (34/46) and 71.74% (33/46) respectively in breast carcinoma tissues. The positive rate of COX-2 and VEGF-C was 86.48% (32/37) and 81.08% (30/37), and LVD was (13.350?3.097)/?200 in the lymph node metastasis group, while that in non-lymph-node metastasis group was 22.22% (2/9), 33.33% (3/9) and (9.560?2.031)/?200 respectively, with significant difference between the two groups (P

Objective:To investigate the relationship of TNF-A-863 and CGRP979 gene polymorphisms with the susceptibility to severe chronic periodontitis in Chinese.Methods:Buccal swabs were collected from 100 adult patients with severe chronic periodontitis and 118 healthy adult controls.DNA was extracted from each subjects of the two groups.PCR-LDR technique was used to identify the genotypes of TNF-A-863 and CGRP979.The difference in the genotypes between the two groups was analyzed by statistics software.Results:The genotype of TNF-A-863 was mainly TNF-A-863 A/C in patients with severe chronic periodontitis and TNF-A-863 C/C in healthy controls.There were significant differences in TNF-A-863 distribution between the two groups(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.
