Comparative example 1
The difference from example 1 is that the raw material was pulverized and sieved through a 80 mesh sieve.
Comparative example 2
The difference from example 1 is that the fine drug powder and the base are mixed at a rotation speed of 100 r/min.
Comparative example 3
The difference from example 1 is that the mixing time of the drug fine powder and the base is 20 min.
Comparative example 4
The difference from example 1 is that the matrix ratio is 95% and the drug is 5%.
Comparative example 6
The difference from example 1 is that the ratio of the matrix is 80% and the drug is 20%.
The prepared traditional Chinese medicine external patch has overlarge viscosity, and poor application effect and body feeling.
Comparative example 7
The difference from example 1 is that the heating temperature in step (4) is 72 ℃.
The heating time is too long, so that the viscosity of the matrix material is changed, and the effect of the prepared traditional Chinese medicine external patch is weakened.
Firstly, clinical curative effect observation:
the effect of the patch of the present invention (examples 1 to 4) and the patch of the control group (comparative examples 1 to 7) and the patch of the traditional Chinese medicine for external use (control group) for treating gouty joint pain sold in the pharmacy were observed and verified on the treatment effect of gouty joint pain.
1100 gouty arthritis patients were selected and randomly divided into 11 groups of 100 patients each. There was no statistical difference in age, sex, course of disease, and level of joint pain for each group (p > 0.05).
The treatment method comprises the following steps:
the patch is directly applied to the joint, 1 day, and 12 days is a treatment course.
And (3) judging standard:
1. and (3) healing: the pain of the joints disappears or basically disappears, the joint movement returns to normal, and the joint swelling phenomenon does not exist;
2. the method has the following advantages: the joint pain is improved, the joint movement is slightly limited, and the slight joint swelling phenomenon can be accompanied;
3. and (4) invalidation: joint pain is not obviously improved or even aggravated, joint movement is limited, operation is strong, and severe joint swelling can be caused.
And (3) test results:
the statistical results of the clinical efficacy of each test group after 12 days of treatment are shown in table 1 below.

The patients have routine treatment before and after treatment, and have no abnormality in liver and kidney function and electrocardio. The gout treated by the patch prepared by the invention is not subjected to late revisitation, and joint swelling and nodules caused by gout do not appear.
As can be seen from Table 1, after 12 days of treatment, the patients who used the patch of the present invention were substantially cured, while the effective rates of comparative examples 1 to 7 of the patch which was not prepared according to the preparation method of the present invention were substantially 90% or less, indicating that the patch of the present invention for treating gouty joint pain was more effective after the treatment according to the specific preparation method of the present invention. The treatment effect of the patch sold in a pharmacy after 12 days is obviously poor.
Secondly, ibuprofen is generally given to patients with gouty arthritis for treatment in the present clinic, and in order to verify the effect of the patch prepared by the invention, the following verification is carried out:
70 patients with acute gouty arthritis (all male) were selected and randomized into control (ibuprofen alone) and treatment (the patch prepared in example 1 was used in conjunction with ibuprofen) groups of 35. The treatment time is 12 days, and laboratory indexes (erythrocyte sedimentation rate (ESR), blood Uric Acid (UA), C-reactive protein (CRP)) before and after treatment of the patient, traditional Chinese medicine symptom evaluation, joint swelling, activity degree and other evaluations, pain reaction of the patient and adverse reaction conditions are observed.
The results show that:
1) after treatment, the ESR, UA and CRP levels of the patients in the two groups are lower than those before treatment (P < 0.05), and the difference between the groups has no statistical significance.
2) Compared with traditional Chinese medicine symptom evaluation, the treatment group is lower than the control group (P < 0.05).
3) Joint swelling and mobility evaluation, and the difference between groups has no statistical significance.
4) The time for complete relief of joint pain is shorter in the treatment group than in the control group (P < 0.05).
5) The blood, urine and feces before and after treatment of the two groups of patients are conventional, and the liver and kidney function and the electrocardio function are not abnormal.
The clinical treatment results show that when the ibuprofen is combined to treat acute gouty arthritis, the clinical symptoms of patients can be obviously improved, the course of disease is shortened, the traditional Chinese medicine external patch prepared by the invention has a good treatment effect on gouty joint swelling and pain, and if the oral administration of a medicine is not needed, the patch can be selected to have a treatment effect; or the composition is used together with oral medicines, so that the course of disease is shortened, the pain is reduced, and the selection range of patients is enlarged.
Case (2):
wangzhi, female age 45, gouty joint pain of 3 years, limb joint pain, inconvenient movement and great pain. After the patch is used for 6 days, the swelling disappears, the pain is relieved, and after the patch is used for 6 days, the patch is recovered to be normal and the patient is cured clinically.
Li Zeng, male, 38 years old, acute gout for 1 year, and has no significant effect when taking Chinese and Western medicines. When the patch is used for 1 patch every day, the pain is relieved after 3 days, the symptoms are obviously improved after the patch is continuously used for 9 days, the pain basically disappears, and the symptoms disappear after the patch is continuously used for one month.
Qianzhi, a man aged 58 years old, suffered from osteoarthritis for 5 years, had swelling and pain in joints of limbs, and was unable to walk. The pain disappears after the patch is used for 12 days, and the pain moves freely after 1 treatment course.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included therein.
