Mutual promotion, mutual assistance and mutual inhibition are commonly for the compatibility of Chinese herbs, but they are also existed among the acupoints. In the paper, the relevant literature on acupoint, compatibility was collected and the mutual promotion, mutual assistance and mutual inhibition relationships of acupoints were described. The laws of the above mentioned combinations, the theoretic evidences and modern researches were summarized briefly. The mutual promotion and mutual assistance refer to the coordination of acupoints, presenting the relationship of the primary and the secondary about the mutual assistance. Hereby, the acupoints could be divided into the simple assistant acupoints and the acupoints from the affected meridians. The mutual inhibition is used to describe the antagonism effect in acupoint combination. There are more researches on the mutual promotion of acupoint combination but less ones on the mutual inhibition and its mechanism is just hypothetic. It is very important to have the deep study on those compatibility relationships for the improvement of acupuncture efficacy and to elaborate the effect mechanism.

BACKGROUND:There are many kinds of ways to obtain osteoblasts at present, but how to get high-purity osteoblasts in a easy and fast way has become a hot research.
OBJECTIVE:To explore a method to get massive and high purified osteoblasts effectively by comparing three common primary osteoblast culture methods, and to observe the biological characteristics of the osteoblasts from the skul of neonatal rabbit.
METHODCalvarias were dissected from newborn New Zealand white rabbits within 24 hours, and osteoblasts were isolated with bone tissue method, col agenase digestion method and modified tryptase and col agenase sequential digestion method respectively, then the cells were subcultured in vitro. Osteoblast proliferation and osteogenic activity were identified by inverted microscope for morphology observation. The rate of living osteobalsts was counted with trypan blue staining. The growth curve of the cells was drawn with MTT method. Alizarin red staining was applied to detect alkaline phosphatase and osteocalcin protein in the cellculture supernatants. Col agen I and col agen III immunohistochemical staining was also performed. RT-PCR was used to determine the expression of osteocalcin and col agen I mRNA expression.
RESULTS AND CONCLUSION:The cultured cells showed highly homogeneous appearance with active proliferation, and they had the typical features of osteoblasts. Alizarin red staining and col agen I immunohistochemical staining were both positive, while col agen III immunohistochemical staining was negative. Alkaline phosphatase and osteocalcin protein expression in the cellculture supernatants can be detected. The expression of osteocalcin and col agen I mRNA was positive in the RT-PCR test. Compared with col agenase digestion method, the modified tryptase and col agenase I sequential digestion method cost less time, presented higher production of osteoblasts and higher cellsurvival rate (P<0.05). Bone tissue method was the easiest method and did the least damage to osteoblasts, but it presented lowest production of osteoblasts and cost the maximum time among the three methods. So it cannot be used in large-scale osteoblast culture. A large quantity of high purity osteoblasts were obtained by modified trypsase and col agenase I sequential digestion method, which can be used as a reliable and efficient way to obtain the original generation osteoblasts in vitro.

Objective To evaluate the possible effect of percutaneous transluminal coronary angioplasty(PTCA) on myocardial injury. Methods Serum cTnI and CK MB levels were measured in 173 patients with coronary artery disease undergone PTCA before and 6, 12, 24, 48 and 72 hours after the procedure. Cardiac events during follow up in these patients were recorded. Results Serum cTnI level was increased after PTCA in 42 patients, remained normal in 84, and was over baseline level before and after the procedure in 47. Serum CK MB level was above baseline before and after the procedure in one patient and increased in 10. Compared with normal cTnI group, elevated cTnI was related to total balloon inflation time, total pressure, number of dilation and stents deployed, contrast medium dose and occurrence of angina during balloon inflation ( P 0.05). Conclusion cTnI was more sensitive and specific than CK MB in identifying minor myocardial injury during PTCA. This injury was related to the intensity of PTCA, but not enough to make worse influence on overall outcome.

BACKGROUND: It has become a hot issue to treat malignant tumors with retroviral mediated cytokines. But it remains a controversy whether retroviral mediated γ-interferon(IFN-γ) is valid in killing glioma cells and prolonging the survival of tumor carriers.OBJECTIVE: To observe the effect of retrovital mediated γ-interferon on the growth of glioma and the survival of tumor-carrying rats.DESIGN: Completely ramdomized trial based on animals.SETTING: Neurosurgery department of a hospital affiliated to a university.MATERIALS: The trial was conducted in the Neurosurgery Institute of Harbin Medical Unicersity from July 2002 to July 2004. The subjects were 60 male Wistar rats provided by the Animal Center of the First Affiliated Hospital of Harbin Medical Unicersity. They were randomly assigned into 3groups: C6 control group, C6/PA317neo control group and C6/PA317IFN-γ treatment group, 20 in each group.INTERVENTIONS: Retroviral vector containing murine IFN-γ gene was transferred into retroviral package cell PA317. A high titer PA317IFN-γ cell line was obtained after G418 resistance screening. In the right basal ganglion area 1 × 106 C6 cells was injected in each of the rats. The rats in C6groups received no more intervention. Those in C6/PA317neo control group received injection of 1 × 106 PA317IFN-γ cells in the right basal ganglion 4days after C6 injection. Those in C6/PA317IFN-γ treatment group received injection of 1 × 106 PA317IFN-γ cells in the right basal ganglion 4 days after selected from each group to be kill, and the brains were taken out to make frozen sections for SABC immunohistochemical staining. The CD4 and CD8 T was measured with imaging processing software under microscope.RESULTS: The mean survival time of rats in C6 and C6/PA317neo control groups was(27.10 ± 0.82) days and (26.60 ± 0.93) days respectively( P ＞ 0.05), while that in treatment group was(49.30 ± 4. 17) days and there were five rats outlived beyond 60 days( P ＜ 0.01 vs the two controls). The tumor volume in the two control groups was of no difference but the tumor volume in treatment was significantly smaller than that in control groups( P ＜ 0. 01 ) . The CD4 and CD8 lymphocytes infiltration in treatment group was more than that in control groups( P ＜ 0.01) and there was no difference between the two controls( P ＞ 0.05) . It was also revealed through immunohistochemical examination that in treatment group there was Brdu positive cells on the 7th day and they disappeared on the 16th day. But there was no Brdu positive cells in the control groups.CONCLUSION: Intratumor injection of PA317IFN-γ induces anti-tumor immunal reaction in rats. Retroviral mediated IFN-γ inhibits tumor growth and prolongs rat survival.

Objective To evaluate the short-middle term clinical effects of the fixed platform stabilized prosthesis in the treatment of the elderly patients with rheumatoid arthritis(RA).Methods The clinical data of 53 cases elderly RA patients who were admitted to the People's Hospital of Liuzhou from January 2009 to January 2013 and were treated with fixed platform and stable prosthesis in 62 knees were retrospective analyzed.Results Fifty-three patients were followed up for 24.0-43.0 months with average (25 ± 2.1)months.At the last follow-up,the degree of knee motion was improved significantly compared with the preoperative((116.0±6.0) ° vs.(46.0±7.0)°),the difference was significant(t=35.323,P＜0.01).The HSS score was significantly improved compared with the preoperative ((85.3±7.6) points vs.(50.2±11.3)points),the difference was significant (t=4.002,P＜0.05).At the last follow-up,35 cases (66.0％) of excellent,11 cases (20.8％) of good,and 7 cases (13.2％) of normal.After the operation,all patients obtained obvious improvement in joint pain,swelling,dysfunction,deformity and so on.Conclusion The fixed platform stabilized prosthesis is simple,effective,and less postoperative complications,and it is a better choice for the elderly patients with high flexion activity.

Objective:To determine whether ox-LDL (oxdized low-density lipoprotein) is highly deposited on the uremic vessel wall and its influence on the vascular remodeling. Methods: Segments of radial arteries were obtained from 21 uremic subjects during the operation of A-V fistula prior to hemodialysis. Segments of internal thoracic arteries of similar diameter were obtained from patients with benign chest tumors as control.The vascular lesions and ox-LDL, CD68,MCP-1, eNOS,ET-1, PCNA,FN on the vessel wall were determined by means of H-E stain and immunohistochemistry. Results： With H-E stain,atherosclerotic plaques were found in the radial arteries of 4 uremic patients. The middle layer of the arteries in uremic patients were obviously thickened, and the T/D　(thickness of the wall/external diameter) ratio was significantly higher than those in control group(P<0.01). ox-LDL,CD68,MCP-1, ET-1, PCNA,FN on the vessel wall in uremic patients were much higher than those in control group (P<0.01). Moreover, ox-LDL on the vessel wall was positively related to the expression of other above mentioned substances on the vessel wall (P<0.01). Whereas the expression of eNOS on the vessel wall was lower than control group (P<0.01),and was negatively related to ox-LDL on the vessel wall(P<0.01). Conclusion: ox-LDL is an important factor contributing to uremic vascular remodeling by increasing the migration,adhesion and infiltration of monocyte,the proliferation of vascular smooth muscle cell and dysfunction of endothelia.

Objective:To explore the efficacyof direct anterior approach (DAA) combined with direct posterior approach (DPA) for the treatment of Pipkin IV fracture.Methods:Data of 18 patients with Pipkin IV fracture treated through DAA combined with DPA from January 2016 to April 2019 was retrospectively analyzed. There were 13 males and 5 females, with an average age of 43.2 years (range,19-56 years). Fractures were caused by traffic accident in 15 and by falling in 3. The fracture lines of 13 cases were located below the fovea of the femoral head and 5 cases were located above the fovea. According to Letournel-Judet classification for acetabular fractures, there were 14 cases of posterior acetabular wall fractures, 2 cases of posterior wall fractures involving posterior column, and 2 transverse plus posterior wall fractures. The operation was performed through DAA approach to treat the femoral head fractures, and DPA approach was used to treat acetabular fractures. Radiographs and CT scans of the pelvis were reexamined after surgery, and fracture reduction, healing, and complications such as femoral head necrosis, sciatic nerve injury, superior gluteal neurovascular injury and heterotopic ossification were evaluated. Quality of acetabular reduction was evaluated according to the criteria proposed by Matta. Thompson-Epstein scoring system was used to evaluate hip function.Results:The average operation time was 133 min (range, 75-205 min). And the average blood loss was 371 ml (range, 240-600 ml). All 18 patients were followed up for 6 to 36 months, with an average period of 15.7 months. All fractures healed 10 to14 weeks after surgery. Three patients had symptoms of sciatic nerve injury after the injury, who recovered 6 to 12 weeks after the operation. All femoral head fractures were reduced. According to Matta criteria of reduction quality, anatomic reduction was gained in 13 cases, and satisfactory reduction was obtained in 3 cases, while unsatisfactory reduction was found in 2 cases, and the overall satisfactory rate was 88.9%(16/18). Two patients had Brooker I level heterotopic ossification. There was no iatrogenic vascular injury, avascular necrosis of femoral head, infection, internal fixation failure or other complications. According to the Thompson-Epstein scoring system at the latest follow-up, the functional results of the affected hip were excellent in 7 cases, good in 8, fair in 2 and poor in 1.Conclusion:Treatment of Pipkin IV fractures through DAA combined with DPA approach reduces surgical invasion. And it can directly reduce and fix the femoral head and posterior acetabular fracture, and protect the important structures such as the arteriae circumflexa femoris medialis, sciatic nerve and lateral femoral cutaneous nerve, and reduce the occurrence of complications such as femoral head necrosis and heterotopic ossification. Therefore, DAA combined with DPA is aneffective method for the treatment of Pipkin IV fractures.
