OBJECTIVE: To quantitatively study the biomechanical parameters of Bachuorounian manipulation in the treatment of humeral epicondylitis, and discuss the effects of individual characteristics on the biomechanical parameters were discussed. METHODS: From July 2019 to February 2020, 40 patients with external humeral epicondylitis were selected, including 18 males and 22 females, ranging in age from 20 to 50 years old, with an average of (34.37±8.41) years old;and the course of disease ranged from 1 to 11 months, with a mean of (6.05±2.71) months. The biomechanical parameters of the elbow joint of the affected side were measured by using the biomechanical sensor. At thesame time, the individual characteristic parameters of patients were collected to analyze the influence of different individual characteristics of patients on biomechanical parameters. RESULTS: The results of mechanical analysis in each stage of the bachuorounian manipulation were as follows:the rolling back rotation force was (31.17±2.99) N;the buckling bending drawing force was (44.99±2.38) N;the rolling pre rotation force was (31.03±2.75) N;and stretching drawing force was (48.75±2.09) N. The correlation analysis between the parameters showed that there was a significant positive correlation between the buckling bending drawing force and the stretching drawing force parameters, and a significant positive correlation between the rolling force back-rotation force and the rolling pre-rotation force parameters. The multivariate linear regression analysis on the parameters of influencing factors and manipulative biomechanics showed that there was a significant correlation between body weight and rolling back-rotation force, significant correlation between elbow tenderness and the buckling bending drawing force, and significant correlation between disease duration and the stretching drawing force. CONCLUSION The bachuorounian manipulation of humeral epicondylitis has a certain range of operating force. Manipulation of each stage has a correlation and systematic. The patient's weight, elbow tenderness and disease course are important factors affecting the bachuorounian manipulation.

OBJECTIVETo study the efficacy and safety of voluntary rehabilitation exercise in the treatment of knee osteoarthritis, based on the traditional Chinese medicine theory of "treating muscle for bone".

METHODSNinety participants with early knee osteoarthritis were randomly divided into experimental group (=45) and control group (=45). Patients in experimental group were treated with voluntary rehabilitation exercise combined with isometric extension of quadriceps femoris. Patients in control group were treated with apparatus training combined with isometric extension of quadriceps femoris. The treatment course lasted for two weeks. Visual analogue scale (VAS), Lysholm score and total therapeutic effect were evaluated before and after treatments.

RESULTSAfter two weeks of treatment, cure-remarkable-effective rate in experimental group (86.67%) was higher than that in control group (71.11%). The VAS scores and Lysholm scores were significantly improved in both two groups (<0.05). The results were significantly better in experimental group those in control group (<0.05). There were no serious adverse events.

CONCLUSIONSVoluntary rehabilitation exercise combined with isometric extension of quadriceps femoris was effective and safe in the treatment of early knee osteoarthritis.

OBJECTIVESTo study the effects of Sanqi qisodium hyaluronate gel on collagen-I and collagen-III expression in the process of rabbits' epidural scar formation after operation.

METHODSNinety-six white rabbits with 6-month-old, half males and half females, weighted from 2 to 2.5 kg, which were randomly divided into normal saline group (A), Sanqi group (B), qisodium hyaluronate group (C) and Sanqi qisodium hyaluronate gel group (D). The laminectomy of rabbits were performed in group A, B, C, D, the duras were surrounded with normal saline, Sanqi liquid, qisodium hyaluronate and Sanqi qisodium hyaluronate gel respectively. Animals of each group were killed at 1, 2, 4, 8 weeks after operation. Use Masson staining for histological observation of collagen, and in situ hybridization staining for the analysis of collagen-I and collagen-III expression.

RESULTSIn the Masson staining, Sanqi qisodium hyaluronate gel group was more regular than the control group in the shape of collagen texture. As to the expression of collagen-I, and Sanqi qisodium hyaluronate gel group was lower than normal saline group, the Sanqi group and qisodium hyaluronate group at 4 weeks after using medicine (P < 0.01); while the Sanqi qisodium hyaluronate gel group was higher than normal saline group, Sanqi group and qisodium hyaluronate group in the collagen-III expression (P < 0.01).

OBJECTIVETo provide a quantitative base for diagnosing cervical vertigo by establishing a biomechanics method.

METHODSFrom July 2004 to Nov 2005, the static posturography (SPG) of normal 86 health individuals and 75 patients with cervical vertigo were quantitatively measured and qualitative diagnosis respectively in closed and open eyes. There were 40 male and 46 female in health adults, ranging from 20 to 74 years old (mean 30 years). There were 16 male and 59 female in vertigo patients, ranging from 20 to 74 years old (mean 44.5 years). In contrast to current diagnosis method of patients with cervical vertigo, the clinical value was evaluated.

RESULTSUnder the state of closed eyes, the sensitivity of SPG diagnosing cervical vertigo was 76%; the specificity was 93%; the Youden index was 69%; the coincidence was 85.1%; the positive predictive value was 90.5%; the negative predictive value was 93%; the positive and negative likelihood ratio were 10.893 and 0.258 respectively. Under the state of open eyes, the sensitivity was 49.3%; the specificity was 87.2%; the Youden index was 38.6%; the coincidence was 69.6%; the positive predictive value was 77.1%; the negative predictive value was 87.2%; the positive likelihood ratio was 3.857; the negative one was 0.581. Regardless of closed or open eyes, foreword-backward type shift orbit was the with cervical vertigo.

CONCLUSIONThe patients with cervical vertigo and normal individuals can be diagnosed objectively and quantitatively with SPG under the state of closed eyes, which can achieve the basic requirements of diagnosing cervical vertigo with validity, reliability and good clinical application. However, the rate of missed diagnosis with SPG under the state of open eyes is too high to meet the diagnostic needs.

OBJECTIVETo observe the efficacy and features of treating early-to-middle stage nontraumatic osteonecrosis of femoral head (NONFH) patients by Jianpi Huogu Recipe (JHR).

METHODSUsing retrospective paired control method, early-to-middle stage NONFH patients treated by JHR and followed-up for 2 years were recruited as the test group (47 cases). Those accepted surgery of core decompression, focus debridement and bone graft were recruited as the control group (48 cases). Radiographic images and clinical data of patients were collected before and after treatment. The stable rate and excellent rate of Harris score were taken as efficacy evaluation indicators.

RESULTS(1) There was no statistical difference in excellent rate of Harris score between the two groups (95.74% vs. 79.17%, P > 0.05). But better effects were obtained in the test group in relieving pain, improving joint deformation, joint mobility, and total Harris score (P < 0. 05, P < 0. 01). There was no statistical difference in the stable rate of radiography between the two groups (74.47% vs. 75.00%, P > 0.05). (2) There was no statistical difference in the stable rate of radiography at phase II and Ill [staging by Association Research Circulation Osseous (ARCO)] between the two groups (82.05% vs. 80.00%, 37.50% vs. 50.00%, P > 0.05). (3) The stable rate of radiography and excellent rate of Harris score were obviously higher in ARCO phase II patients than in ARCO phase Il patients (82.05% vs. 37.50%,97.44% vs. 87.50%, P < 0.01).

CONCLUSIONSEquivalent stable rate of radiography to that of surgery could be obtained in treating early-to-middle stage NONFH patients by JHR. But it was better than surgery in relieving pain, improving joint deformation and joint mobility.

OBJECTIVETo observe the X-ray features of bone damage in patients with moderate endemic skeletal fluorosis and the changes of X-ray after treatment with herbal therapy.

METHODSFrom 2007.12 to 2009.8,114 patients with moderate endemic skeletal fluorosis were randomly divided into treatment group and control group by central randomization system. There were 60 patients in treatment group including 26 males and 34 females,aged from 39 to 60 years with an average of (51.68 +/- 4.98) years; There were 54 patients in control group included 30 males and 24 females, aged from 39 to 60 years with an average of (52.15 +/- 4.86) years. Both treatment and control groups were treated with basic treatment including calcium supplementation and preparation stage with herb decoction. Patients were orally given 600 mg Caltrate everyday for calcium suptrointestinal function and promoting the digestion and absorption of herb decoction for 3 days. Patients in treatment group were rally given Guo's Maqian decoction(200 ml,twice daily) for 8 weeks. Eight weeks later,Guo 's Maqian decoction was replaced y Guokangning capsule (0.44 g per cansule,2 capsules,three times daily) for 4 weeks. The treatment course lasted 12 weeks. The time for followed-up after treatment was 24 weeks. When the treatment finished, 7 experts on orthopaedics and radiology evaluated and statistically analyzed the X-ray features pre and post treatment,using expert evaluation scale (including the appearance and changes of osteosclerosis,osteoporosis softening,joint changes close to the bone and mixed changes) designed referring endemic skeletal fluorosis X-ray findings and sub-degree standard(WS192-2008).

RESULTSAll X-ray features of endemic skeletal fluorosis appeared in the X-ray of the 114 patients with moderate endemic skeletal fluorosis. Osteosclerosis: 4 cases in forearm, 7 in calf,4 in pelvis,4 in lumbar vertebrae ;Osteoporosis and bone softening: 23 cases in forearm patients, 23 in calf, 5 in pelvis, 8 in lumbar vertebrae; Mixed changes: 6 cases in forearm, 9 in calf, 10 in pelvis, 1 in lumbar vertebrae patients; oint changes: 107 cases in forearm, 47 in calf, 28 in pelvis, 19 in lumbar vertebrae. There were X-ray no changes before and after the treatment in all of parts in control group. In treatment group, there were only 2 patients showed extraperiostealin and joint changes after the treatment, in which one showed better ossification of interosseous membrane of leg and another one showed disappearance of the lateral hyperplasia of the left pelvic acetabulum. There were no changes between before and after treatment in X-ray of all parts in the rest patiens of the treatment group. There was no significant difference between before and after treatment in both groups (P > 0.05).

OBJECTIVETo explore the reason,diagnose outline,therapeutic tool of the incisions deep infections at early stage after lumber internal fixation.

METHODSFrom January 2001 to December 2011, 10 patients with incisions deep infections at the early stage after the posterior lumber internal fixation were treated with intervertebral space lavaging. There were 1 male and 9 females with an average age of 63 years, and an average infection started at the 6th day after operation. The main clinical features including backleg pain aggravating, fervescence, fresh seepage from the wound, and blood inflammatory index increased, etc. According to whether the wound could heal at the first treatment stage as a evaluation standard of curative effect.

RESULTSTen cases were followed up with an average period of 17 months. The wounds of 9 cases healed at the first stage and no recurrence and complications were found. One case underwent debridgement of many times with the therapic period of 7 months,at last,after taking out the vertebral pedicle bolt,the wound healed,and no recurrence after follow-up of 18 months.

CONCLUSIONThe deep wound infections after the lumber internal fixation should receive intervertebral space lavaging as soon as possible. The method can finally remain internal fixations and obtain satisfactory effects, but avoiding too much tissue cutting and tube setting in the deep intervertebral space are the keys to the successful fixation.
