隐蔽分组方法和过程:
|
顺序号、随机号、组别将由专人放入不透光信封密封,得到A01-A56等56个信封,并交由专人保存,每次有符合纳入标准的患者入组时电话通知,打开相应顺序的信封,确定进入1组或者是2组。管理信封人员不知道1、2组代表的含义;同理得到B01-B20等20个B组信封;C01-C20等20个C组信封。三组信封共有96个,分别分发给各中心,其中中医院56例,另外两个中心各20例患者。所有患者进入两干预组的机会均等,得到对照组48例和治疗组48例。

Process of allocation
concealment:
|
The sequence number random number and group will be sealed in opaque envelopes by special personnel and 56 envelopes such as A01-A56 will be kept by special personnel. Every time a patient who meets the inclusion criteria enters the group he will be notified by telephone and the envelopes in the corresponding sequence will be opened to determine whether to enter the first group or the second group. Envelope managers don't know the meaning of group 1 and group 2 representatives; In the same way 20 group B envelopes such as B01-B20 are obtained. C01-C20 and other 20 group C envelopes. There were 96 envelopes in three groups which were distributed to various centers including 56 cases in Chinese medicine hospitals and 20 cases in the other two centers. All patients have equal opportunities to enter the two intervention groups and 48 cases in the control group and 48 cases in the treatment group were obtained.

盲法:
|
本研究由于干预措施不能对患者社盲,故在纳入病例及随访评估方面对相应研究人员设盲,尽量减小信息偏移。由于三个中心分别纳入患者,各自接诊医师纳入患者入组时不知道随机数字表编号方式,也不知道纳入的顺序号,只有负责信封的专人知道纳入的顺序号,只有打开信封揭盲后才知道患者的组别。管理药物、指导功法、手法治疗的研究人员进行各自操作,治疗前后由观察表填写医师,进行表格填写,并由非治疗与非功法人员进行数据录入及数据分析。接诊、功法指导、手法治疗人员、随访人员、数据分析人员不知道分组名单;信封管理人员不接触患者;功法指导人员不填写评估报告;填写报告表的医师不进行治疗及指导。

Blinding:
|
In this study because the intervention measures can't be blind to the patients' society we should be blind to the corresponding researchers in the aspects of case inclusion and follow-up evaluation so as to minimize the information deviation. As patients are included in the three centers respectively the attending doctors do not know the numbering method of the random number table or the sequence number when they are included in the group. Only the person in charge of the envelope knows the sequence number and the group of patients is not known until the envelope is opened. The researchers who manage drugs instruct manual therapy and manual therapy perform their own operations. Before and after treatment the observation form is filled in by doctors the form is filled in and the data is entered and analyzed by non-therapeutic and non-manual therapy personnel. Reception exercise guidance manual therapy personnel follow-up personnel and data analysis personnel do not know the grouping list; Envelope managers do not touch patients; The instructor does not fill in the evaluation report; Doctors who fill in the report form do not give treatment and guidance.

揭盲或破盲原则和方法:
|
CRF表格录入完毕后可揭盲。当发生的不良事件处理有赖于所用药物的种类时,由主要研究者决定拆阅,并做好相应的记录,该受试者将被终止试验,并作脱落病例处理,同时将处理结果通知监查员。
|
Rules of uncover or
ceasing blinding:
|
Blind can be revealed after CRF form is entered. When the treatment of adverse events depends on the type of drugs used, the principal investigator will decide to open them and make corresponding records, and the subject will be terminated, and the case will be treated, and the supervisor will be informed of the treatment results.

统计方法名称:
|
将符合研究方案,符合纳入标准的腰椎间盘突出症患者、同时不符合排除标准、不符合剔除标准、完成治疗方案的病例集合数据集(PPS),由经统一培训录入人员,以主持单位采用双人双输的办法进行临床观察表数据的录入、校对、数据库链接和转化,生成SPSS19.0数据库文件。年龄、VAS、JOA、Oswestry数据作为入组基线标准,用均数±标准差(`x±s)表示;患者的年龄、用药量、评分数值计量资料采用T检验或非参数检验;性别、两组治疗总体有效率等计数资料采用χ2检验,并使用CMH卡方检验、协方差分析矫正中心效应,比较两组治疗前后的总体有效率,p<0.05为具有统计学差异,p<0.01为具有显著统计学差异。

Statistical method:
|
The case set data set (PPS) of patients with lumbar disc herniation who meet the research scheme, the inclusion criteria, the exclusion criteria and the treatment scheme are not met, and the data of clinical observation table are entered, proofread, linked and transformed by the host unit with the method of double lose, and the SPSS19.0 database file is generated. The data of age, VAS, JOA, and Oswestry were used as the baseline criteria, which were expressed by the mean standard deviation (x±s). T test or nonparametric test was used to measure the patient's age, dosage and score. The statistical data such as gender and the total effective rate of the two groups were tested by χ2 test, and the central effect was corrected by CMH chi-square test and covariance analysis. The total effective rate of the two groups before and after treatment was compared, with p<0.05 being statistically different and p<0.01 being statistically different.

参照2012年国家中医药 管理局发布的《中医病证诊断疗效标准》中LDH的疗效标准:①治愈:腰腿痛消失,直腿抬高70°以上,能恢复原工作;②好转:腰腿痛减轻,腰部活动功能改善;③未愈:症状、体征无改善。总有效率(%)=(治愈例数+好转例数)/总例数×100%。
1、日本矫形外科协会腰椎治疗评价表(Japanese orthopaedic association, JOA) 测定:其内容包括主观症状 9分(腰部疼痛 3 分,腿痛或麻 3 分,步行能力 3 分)、体征 6 分(直腿抬高 2 分,感觉障碍 2 分,运动障碍 2 分)、日常生活活动能力受限 14 分(包括卧位转身、站立、洗漱、身体前倾、坐 1 小时、举物、持物等)和膀胱功能 6 分(正常:0 分,轻度失控:3分,严重失控:6 分)。满分为 29 分,<10分,差;10-15分中度;16-24 良好;25-29 优。分别在治疗前后进行评定。
2、Oswestry 功能障碍指数(Oswestrydisabilityindex,ODI) 测定:每项评分是 0~5 分,最高得分为 45 分,考虑到国人对“性功能”指标的保守性,这一项剔除在外,否则满分为50分。因其是一种单项、主观指标,方便简单,清晰易懂,受试者通常在5分钟内完成,1分钟就能计算出分数。
3、VAS疼痛评分测定:0 分为无痛;1~3 分为轻度疼痛;4~6 分为中度疼痛;7~l0 分为重度疼痛。

Calculated Results ater
the Study Completed:

According to the therapeutic standard of LDH in the "Therapeutic Standard for Diagnosis of TCM Diseases and Syndrome" issued by state administration of traditional chinese medicine in 2012: ① Cure: the pain in waist and legs disappears, and the straight leg can be raised by more than 70 degrees, and the original work can be resumed; ② Improvement: Lower back and leg pain is relieved, and the function of waist movement is improved; ③ Not healed: symptoms and signs have not improved. Total effective rate (%) = (cured cases+improved cases)/total cases ×100%.
1. Japanese Orthopaedic Association (JOA) measurement: Its contents include 9 points for subjective symptoms (3 points for waist pain, 3 points for leg pain or numbness, 3 points for walking ability) and 6 points for physical signs (2 points for straight leg elevation and 2 points for sensory disturbance. Dyskinesia score 2), limited ability of daily living score 14 (including turning around, standing, washing, leaning forward, sitting for 1 hour, lifting and holding things, etc.) and bladder function score 6 (normal: 0, mild out of control: 3, severe out of control: 6). Full score is 29, < 10, poor; 10-15 points are moderate; 16-24 Good; 25-29 excellent. They were evaluated before and after treatment.
2. Determination of Oswestry Disability Index (ODI): Each score is 0 ~ 5, with the highest score of 45. Considering the conservatism of Chinese people on the "sexual function" index, this item is excluded, otherwise the full score is 50. Because it is a single and subjective index, it is convenient, simple, clear and easy to understand. Subjects usually finish it in 5 minutes, and the score can be calculated in 1 minute.
3. VAS pain score measurement: 0 is painless; 1 ~ 3 is divided into mild pain; 4 ~ 6 is divided into moderate pain; 7 ~ l0 is classified as severe pain.
